FORWARD-LOOKING STATEMENTS

        This Annual Report on Form 20-F for the year ended December 31, 2018 (this "Annual Report") contains certain forward-looking statements concerning plans and objectives of management for future operations or economic performance, or assumptions related thereto, including our financial forecast. In addition, we and our representatives may from time to time make other oral or written statements that are also forward-looking statements. Such statements include, in particular, statements about our plans, strategies, business prospects, changes and trends in our business, and the markets in which we operate as described in this Annual Report. In some cases, you can identify the forward-looking statements by the use of words such as "may," "could," "should," "would," "expect," "plan," "anticipate," "intend," "forecast," "believe," "estimate," "predict," "propose," "potential," "continue" or the negative of these terms or other comparable terminology. These forward-looking statements reflect management's current views only as of the date of this Annual Report and are not intended to give any assurance as to future results. As a result, unitholders are cautioned not to rely on any forward-looking statements.

        Forward-looking statements appear in a number of places in this Annual Report and include statements with respect to, among other things:

Table of Contents

        Forward-looking statements in this Annual Report are made based upon management's current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties, including those risks discussed in "Item 3. Key Information—Risk Factors." The risks, uncertainties and assumptions involve known and unknown risks and are inherently subject to significant uncertainties and contingencies, many of which are beyond

KNOT Offshore Partners' control. KNOT Offshore Partners cautions that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.

        KNOT Offshore Partners undertakes no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible to predict all of these factors. Further, KNOT Offshore Partners cannot assess the impact of each such factor on its business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statement. KNOT Offshore Partners makes no prediction or statement about the performance of its common units. The various disclosures included in this Annual Report and in KNOT Offshore Partners' other filings made with the Securities and Exchange Commission (the "SEC") that attempt to advise interested parties of the risks and factors that may affect KNOT Offshore Partners' business, prospects and results of operations should be carefully reviewed and considered.

Please read "—Non-U.S. GAAP Financial Measures" below.

Non-U.S. GAAP Financial Measures

        EBITDA and Adjusted EBITDA.    EBITDA is defined as earnings before interest, depreciation and taxes. Adjusted EBITDA is defined as earnings before interest, depreciation, taxes, goodwill impairment charges and other financial items (including other finance expense, realized and unrealized gain (loss) on derivative instruments and net gain (loss) on foreign currency transactions). EBITDA is used as a supplemental financial measure by management and external users of financial statements, such as our lenders, to assess our financial and operating performance and our compliance with the financial covenants and restrictions contained in our financing agreements. Adjusted EBITDA is used as a supplemental financial measure by management and external users of financial statements, such as investors, to assess our financial and operating performance. We believe that EBITDA and Adjusted EBITDA assist our management and investors by increasing the comparability of our performance from period to period and against the performance of other companies in our industry that provide EBITDA and Adjusted EBITDA information. This increased comparability is achieved by excluding the potentially disparate effects between periods or companies of interest, other financial items, taxes, goodwill impairment charges and depreciation, as applicable, which items are affected by various and possibly changing financing methods, capital structure and historical cost basis and which items may significantly affect net income between periods. We believe that including EBITDA and Adjusted EBITDA as financial measures benefits investors in (1) selecting between investing in us and other investment alternatives and (2) monitoring our ongoing financial and operational strength in assessing whether to continue to hold common units.

        EBITDA and Adjusted EBITDA should not be considered alternatives to net income or any other indicator of our performance calculated in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). EBITDA and Adjusted EBITDA exclude some, but not all, items that affect net income, and these measures may vary among other companies. Therefore, EBITDA and Adjusted EBITDA as presented below may not be comparable to similarly titled measures of other companies. The following table reconciles EBITDA and Adjusted EBITDA to net income, the most directly comparable U.S. GAAP measure, for the periods presented.

        Not applicable.

        Some of the following risks relate principally to the industry in which we operate and to our business in general. Other risks relate principally to the securities market and to ownership of our common units. The occurrence of any of the events described in this section could significantly and negatively affect our business, financial condition, operating results or cash available for distributions or the trading price of our common units.

Risks Inherent in Our Business

We may not have sufficient cash from operations following the establishment of cash reserves and payment of fees and expenses to enable us to pay the minimum quarterly distribution on our common units.

        We may not have sufficient cash from operations to pay the minimum quarterly distribution on our common units. Furthermore, distributions to the holders of our common units are subject to the prior distribution rights of any holders of our preferred units outstanding. As of April 10, 2019, there were 3,750,000 Series A Preferred Units issued and outstanding. Under the terms of our partnership agreement, we are prohibited from declaring and paying distributions on our common units until we declare and pay (or set aside for payment) full distributions on the Series A Preferred Units. The amount of cash we can distribute on our units principally depends upon the amount of cash we generate from our operations, which may fluctuate from quarter to quarter based on the risks described in this section, including, among other things:

        In addition, the actual amount of cash we have available for distribution depends on other factors, including:

7


Table of Contents

        The amount of cash we generate from our operations may differ materially from our profit or loss for the period, which is affected by non-cash items. As a result of this and the other factors mentioned above, we may make cash distributions during periods when we record losses and may not make cash distributions during periods when we record net income.

Our ability to grow and to meet our financial needs may be adversely affected by our cash distribution policy.

        Our cash distribution policy, which is consistent with our partnership agreement, requires us to distribute all of our available cash (as defined in our partnership agreement) each quarter. Accordingly, our growth may not be as fast as businesses that reinvest their available cash to expand ongoing operations.

        In determining the amount of cash available for distribution, our board of directors approves the amount of cash reserves to set aside, including reserves for future maintenance and replacement capital expenditures, working capital and other matters. We also rely upon external financing sources, including commercial borrowings, to fund our capital expenditures. Accordingly, to the extent we do not have sufficient cash reserves or are unable to obtain financing, our cash distribution policy may significantly impair our ability to meet our financial needs or to grow.

We must make substantial capital expenditures to maintain the operating capacity of our fleet, which reduces cash available for distribution. In addition, each quarter we are required to deduct estimated maintenance and replacement capital expenditures from operating surplus, which may result in less cash available to unitholders than if actual maintenance and replacement capital expenditures were deducted.

        We must make substantial capital expenditures to maintain and replace, over the long-term, the operating capacity of our fleet. Maintenance and replacement capital expenditures include capital expenditures associated with the removal of a vessel from the water for inspection, maintenance and/or repair of submerged parts (or drydocking) and modifying an existing vessel or acquiring a new vessel to the extent these expenditures are incurred to maintain or replace the operating capacity of our fleet. These expenditures could vary significantly from quarter to quarter and could increase as a result of changes in:

        Our partnership agreement requires our board of directors to deduct estimated, rather than actual, maintenance and replacement capital expenditures from operating surplus each quarter in an effort to reduce fluctuations in operating surplus (as defined in our partnership agreement). The amount of estimated maintenance and replacement capital expenditures deducted from operating surplus is subject

Table of Contents

to review and change by our board of directors and our conflicts committee at least once a year. In years when estimated maintenance and replacement capital expenditures are higher than actual maintenance and replacement capital expenditures, the amount of cash available for distribution to unitholders may be lower than if actual maintenance and replacement capital expenditures were deducted from operating surplus. If our board of directors underestimates the appropriate level of estimated maintenance and replacement capital expenditures, we may have less cash available for distribution in future periods when actual capital expenditures exceed our previous estimates.

If capital expenditures are financed through cash from operations or by issuing debt or equity securities, our ability to make cash distributions may be diminished, our financial leverage could increase, or our unitholders may be diluted.

        Use of cash from operations to expand or maintain our fleet reduces cash available for distribution to unitholders. Our ability to obtain bank financing or to access the capital markets for future offerings may be limited by our financial condition at the time of any such financing or offering as well as by adverse market conditions resulting from, among other things, general economic conditions and contingencies and uncertainties that are beyond our control. Our failure to obtain the funds for future capital expenditures could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders. Even if we are successful in obtaining necessary funds, the terms of such financings could limit our ability to pay cash distributions to unitholders. In addition, incurring additional debt may significantly increase our interest expense and financial leverage, and issuing additional equity securities may result in significant unitholder dilution and would increase the aggregate amount of cash required to maintain our current level of quarterly distributions to unitholders, both of which could have a material adverse effect on our ability to make cash distributions.

Our debt levels may limit our flexibility in obtaining additional financing, pursuing other business opportunities and paying distributions to our unitholders.

        As of December 31, 2018, we had consolidated debt of approximately $1,077.3 million. We have the ability to incur additional debt. Please read "Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources." Our level of debt could have important consequences to us, including the following:

        Our ability to service our debt depends upon, among other things, our future financial and operating performance, which is affected by prevailing economic conditions and financial, business,

regulatory and other factors, some of which are beyond our control. If our operating results are not sufficient to service our current or future indebtedness, we will be forced to take actions such as reducing distributions, reducing or delaying our business activities, acquisitions, investments or capital expenditures, selling assets, restructuring or refinancing our debt, or seeking additional equity capital or bankruptcy protection. We may not be able to effect any of these remedies on satisfactory terms, or at all.

Financing agreements containing operating and financial restrictions may restrict our business and financing activities.

        The operating and financial restrictions and covenants in our financing agreements and any future financing agreements could adversely affect our ability to finance future operations or capital needs or to engage, expand or pursue our business activities. For example, the financing agreements may restrict the ability of us and our subsidiaries to:

        In addition, our financing agreements require us to comply with certain financial ratios and tests, including, among others, maintaining a minimum liquidity, maintaining positive working capital, ensuring that EBITDA exceeds interest payable, maintaining a minimum collateral value, and maintaining a minimum book equity ratio. Our ability to comply with the restrictions and covenants, including financial ratios and tests, contained in our financing agreements is dependent on future performance and may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired.

        If we are unable to comply with the restrictions and covenants in the agreements governing our indebtedness or in current or future debt financing agreements, there could be a default under the terms of those agreements. If a default occurs under these agreements, lenders could terminate their commitments to lend and/or accelerate the outstanding loans and declare all amounts borrowed due and payable. This could lead to cross-defaults under other financing agreements and result in obligations becoming due and commitments being terminated under such agreements. We have pledged our vessels as security for our outstanding indebtedness. If our lenders were to foreclose on our vessels in the event of a default, this may adversely affect our ability to finance future operations or capital needs or to engage in, expand or pursue our business activities. If any of these events occur, we cannot guarantee that our assets will be sufficient to repay in full all of our outstanding indebtedness, and we may be unable to find alternative financing. Even if we could obtain alternative financing, that financing might not be on terms that are favorable or acceptable. Any of these events would adversely affect our ability to make cash distributions to our unitholders and cause a decline in the market price of our common units. Please read "Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources."

Restrictions in our debt agreements may prevent us or our subsidiaries from paying distributions.

        The payment of principal and interest on our debt reduces cash available for distribution to us and on our units. In addition, our and our subsidiaries' financing agreements prohibit the payment of distributions upon the occurrence of the following events, among others:

The failure to consummate or integrate acquisitions in a timely and cost-effective manner could have an adverse effect on our financial condition and results of operations.

        Acquisitions that expand our fleet are an important component of our strategy. We believe that acquisition opportunities may arise from time to time, and any such acquisition could be significant. Any acquisition of a vessel or business may not be profitable after the time of acquisition and may not generate cash flows sufficient to justify the investment. In addition, our acquisition growth strategy exposes us to risks that may harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders, including risks that we may:

        In addition, unlike newbuilds, existing vessels typically do not carry warranties as to their condition. While we generally inspect existing vessels prior to purchase, such an inspection would normally not

11


Table of Contents

provide us with as much knowledge of a vessel's condition as we would possess if it had been built for us and operated by us during its life. Repairs and maintenance costs for existing vessels are difficult to predict and may be substantially higher than for vessels we have operated since they were built. These costs could decrease our cash flows and reduce our liquidity.

        Certain acquisition and investment opportunities may not result in the consummation of a transaction. In addition, we may not be able to obtain acceptable terms for the required financing for any such acquisition or investment that arises. We cannot predict the effect, if any, that any announcement or consummation of an acquisition would have on the trading price of our common units. Our future acquisitions could present a number of risks, including the risk of incorrect assumptions regarding the future results of acquired vessels or businesses or expected cost reductions or other synergies expected to be realized as a result of acquiring vessels or businesses, the risk of failing to successfully and timely integrate the operations or management of any acquired vessels or businesses and the risk of diverting management's attention from existing operations or other priorities. We may also be subject to additional costs related to compliance with various international laws in connection with such acquisition. If we fail to consummate and integrate our acquisitions in a timely and cost-effective manner, our business, financial condition, results of operations and cash available for distribution could be adversely affected.

Our charters are subject to early termination under certain circumstances and any such termination could have a material adverse effect on our results of operations and cash available for distribution to unitholders.

        As of April 10, 2019, our fleet consists of sixteen shuttle tankers. If any of our vessels are unable to generate revenues as a result of the expiration or termination of its charter or sustained periods of off-hire time, our results of operations and financial condition could be materially adversely affected. Each of our charters terminates automatically if the applicable vessel is lost or missing or damage to the vessel results in a constructive total loss. The customer, under certain circumstances, may also have an option to terminate a time charter if the vessel is requisitioned by any government for a period of time in excess of the time period specified in the time charter or if at any time we are in default under the time charter. In addition, either party may usually terminate a charter in the event of the outbreak of war between specified countries. Under our bareboat charters, the charter is deemed terminated as of the date of any compulsory acquisition of the vessel or requisition for title by any governmental or other competent authority. For more information regarding the termination of our charters, please read "Item 4. Information on the Partnership—Business Overview—Charters—Termination."

We may experience operational problems with vessels that reduce revenue and increase costs.

        Shuttle tankers are complex and their operation is technically challenging. Marine transportation operations are subject to mechanical risks and problems. Operational problems may lead to loss of revenue or higher than anticipated operating expenses or require additional capital expenditures. Any of these results could harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

We currently derive all of our time charter and bareboat revenues from seven customers, and the loss of any such customers could result in a significant loss of revenues and cash flow.

        We currently derive all of our time charter and bareboat revenues from seven customers. For the year ended December 31, 2018, Eni Trading and Shipping S.p.A.

        If we lose a key customer, we may be unable to obtain replacement long-term charters and may become subject to the volatile spot market, which is highly competitive and subject to significant price fluctuations. In addition, if a customer exercises its right to terminate a charter, we may be unable to re-charter such vessel on terms as favorable to us as those of the terminated charter. The loss of any of our key customers could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholder

        Oil prices can be volatile, and this could affect the equity value of many of our customers. The combination of a reduction of cash flow resulting from lower prices, a reduction in borrowing under related credit facilities and the limited or lack of availability of debt or equity financing could potentially reduce the ability of our customers to make charter payments, which in turn could harm our business, results of operations and financial condition.

We depend on subsidiaries of KNOT to assist us in operating our businesses and competing in our markets.

        We and our operating subsidiaries have entered into various services agreements with certain subsidiaries of KNOT, including KNOT Management. Under these agreements the subsidiaries provide us with certain administrative, financial and other services. Our operating subsidiaries are provided with substantially all of their crew, technical and commercial management services (including vessel maintenance, periodic drydocking, cleaning and painting, performing work required by regulations and human resources and financial services) and other advisory and technical services, including the sourcing of new contracts and renewals of existing contracts. Our operational success and ability to execute our growth strategy depends significantly upon the satisfactory performance of these services by the KNOT subsidiaries. Our business will be harmed if such subsidiaries fail to perform these services satisfactorily or if they stop providing these services to us or our operating subsidiaries.

        Our ability to compete to enter into new charters and expand our customer relationships depends largely on our ability to leverage our relationship with KNOT and its reputation and relationships in the shipping industry. If KNOT suffers material damage to its reputation or relationships, it may harm the ability of us or our subsidiaries to:

        If our ability to do any of the things described above is impaired, it could have a materially adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Our growth depends on continued growth in demand for shuttle tanker transportation services.

        Our growth strategy focuses on expansion in the shuttle tanker sector. Accordingly, our growth depends on continued growth in the demand for offshore oil transportation services. Factors beyond our control that affect the offshore oil transportation industry may have a significant impact on our business, financial condition, results of operations and ability to make cash distributions to our unitholders. Fluctuations in the hire rate we can charge our customers result from changes in the supply of carrying capacity and demand for the crude oil carried. If a sustained period of reduced demand for crude oil and offshore oil transportation services were to occur it would have a material adverse effect on our future growth and could harm our business, results of operations and financial condition. The factors affecting supply and demand for shuttle tankers and supply and demand for

crude oil transported by shuttle tankers are outside of our control, and the nature, timing and degree of changes in industry conditions are unpredictable.

        The factors that influence the demand for shuttle tanker capacity include:

        The factors that influence the supply of shuttle tanker capacity include:

Declines in oil prices may adversely affect our growth prospects and results of operations.

        Any significant decline in oil prices may adversely affect our business, results of operations and financial condition and our ability to make cash distributions, as a result of, among other things:

Table of Contents

The current state of the global financial markets and current economic conditions may impair our customers' and suppliers' ability to pay for our services and could have a material adverse effect on our revenue, profitability and financial position.

        We depend on our customers' willingness and ability to fund operating and capital expenditures to provide crude oil shuttle tankers for new or expanding offshore projects. Existing and future adverse economic conditions, including low oil prices, may lead to a decline in our customers' operations or ability to pay for our services, which could result in decreased demand for our vessels. There has historically been a strong link between the development of the world economy and demand for energy, including oil and natural gas.

        Global financial markets and economic conditions have been severely disrupted and volatile in recent years and remain subject to significant vulnerabilities, such as the deterioration of fiscal balances and the rapid accumulation of public debt, continued deleveraging in the banking sector and a limited supply of credit. Credit markets as well as the equity and debt capital markets were exceedingly distressed during 2008 and 2009 and while these markets have subsequently recovered, periods of volatility have subsequently occurred. Uncertainty surrounding the continuing sovereign debt crisis in Greece and other European Union member countries, turmoil and unrest in the Middle East, Africa, Korea, the Ukraine and elsewhere and the socioeconomic and political crisis in Venezuela have led to increased volatility in global credit and equity markets. An extended period of adverse development in the outlook for European countries or Brazil could reduce the overall demand for oil and have a negative impact on our customers. Potential developments, or market perceptions concerning these and related issues, could affect our business, financial position, results of operations and ability to make cash distributions to our unitholders.

        Any global financial or credit crisis or disruption may further reduce the availability of liquidity and credit to fund the continuation and expansion of industrial business operations worldwide. Shortage of liquidity and credit combined with uncertainty in worldwide equity markets could lead to an extended worldwide economic recession. Such deterioration of the worldwide economy could result in reduced demand for oil and natural gas, exploration and production activity and transportation of oil and natural gas that could lead to a decrease in the hire rate earned by our vessels and a decrease in new charter activity. In addition, any adverse development in the global financial markets or deterioration in economic conditions might adversely impact our ability to issue additional equity at prices that will not be dilutive to our existing unitholders or preclude us from issuing equity at all.

        We also cannot be certain that additional financing will be available if needed and to the extent required, on acceptable terms or at all. As a result of the disruptions in the credit markets and higher capital requirements, many lenders have increased margins on lending rates, enacted tighter lending standards, required more restrictive terms (including higher collateral ratios for advances, shorter maturities and smaller loan amounts), or have refused to refinance existing debt at all. Furthermore, certain banks that have historically been significant lenders to the shipping industry have reduced or ceased lending activities in the shipping industry. If additional financing is not available when needed, or is available only on unfavorable terms, we may be unable to meet our obligations as they come due or we may be unable to expand our existing business, complete shuttle tanker acquisitions or otherwise take advantage of business opportunities as they arise.

        Furthermore, any uncertainty in the financial markets could have an impact on our customers and/or suppliers including, among other things, causing them to fail to meet their obligations to us. Similarly, any shortage of credit could affect lenders participating in our financing agreements, making them unable to fulfill their commitments and obligations to us. Any reductions in activity owing to such conditions or failure by our customers, suppliers or lenders to meet their contractual obligations to us could adversely affect our business, financial position, results of operation and ability to make cash distributions to our unitholders.

The results of the United Kingdom's ("U.K.'s") referendum on withdrawal from the European Union ("EU") may have a negative effect on global economic conditions, financial markets and our business.

        In June 2016, a majority of voters in the U.K. elected to withdraw from the EU in a national referendum, and in March 2017, the government of the U.K. formally initiated the process. The referendum was advisory, and the terms of any withdrawal are subject to a negotiation period that could last at least two years after the March 2017 initiation. There is currently no agreement in place regarding the withdrawal, creating significant uncertainty about the future relationship between the U.K. and the EU, including with respect to the laws and regulations that will apply as the U.K. determines which EU derived laws to replace or replicate in the event of a withdrawal. Additionally, it remains possible that the U.K.'s membership in the EU ends without any agreement between the U.K. and the EU on the terms of their relationship going forward. The referendum has also given rise to calls for the governments of other EU member states to consider withdrawal. These developments, or the perception that any of them could occur, have had and may continue to have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly reduce global market liquidity and restrict the ability of key market participants to operate in certain financial markets. Any of these factors could depress economic activity and restrict our access to capital, which could have a material adverse effect on our business, financial condition and operating results.

Our growth depends on our ability to expand relationships with existing customers and obtain new customers, for which we face substantial competition.

        One of our principal objectives is to enter into additional long-term, fixed-rate charters. The process of obtaining new long-term charters is highly competitive, usually involving an intensive screening process and competitive bids and extending for several months. Shuttle tanker charters are awarded based upon a variety of factors relating to the vessel operator, including:

        Our ability to win new charters depends upon a number of factors, including our ability to:

16


Table of Contents

        We expect substantial competition for providing services for potential shuttle tanker projects from a number of experienced companies. This increased competition may cause greater price competition for charters. As a result of these factors, we may be unable to expand our relationships with existing customers or to obtain new customers on a profitable basis, if at all, which would have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

An increase in the global supply of shuttle tanker capacity without a commensurate increase in demand may have an adverse effect on hire rates and the values of our vessels, which could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

        The supply of shuttle tankers in the industry is affected by, among other things, assessments of the demand for these vessels by oil companies. Any over-estimation of demand for vessels may result in an excess supply of new shuttle tankers. This may, in the long term when existing contracts expire, result in lower hire rates and depress the values of our vessels. In such an event, our business, financial condition, results of operations and ability to make cash distributions to our unitholders may be adversely affected.

        During periods of high utilization and high hire rates, industry participants may increase the supply of shuttle tankers by ordering the construction of new vessels. This may result in an over-supply of shuttle tankers and may cause a subsequent decline in utilization and hire rates when the vessels enter the market. Lower utilization and hire rates could adversely affect revenues and profitability. Prolonged periods of low utilization and hire rate could also result in the recognition of impairment charges on shuttle tankers if future cash flow estimates, based upon information available at the time, indicate that the carrying value of these shuttle tankers may not be recoverable. Such impairment charge may cause lenders to accelerate loan payments under our financing agreements, which could adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

The required drydocking of our vessels could be more expensive and time consuming than we anticipate, which could adversely affect our cash available for distribution to unitholders.

        We must periodically drydock each of our vessels for inspection, repairs and maintenance and any modifications required to comply with industry certification or governmental requirements. Generally, we drydock each vessel every 60 months until the vessel is 15 years old and every 30 months thereafter. The required drydocking of our vessels could be more expensive and time consuming than we anticipate, which could adversely affect our cash available for distribution. The drydocking of our vessels requires significant capital expenditures and results in loss of revenue while our vessels are off-hire. Any significant increase in the number of days of off-hire due to such drydocking or in the costs of any repairs could have a material adverse effect on our ability to pay distributions to our unitholders. Although we do not anticipate that more than one of the vessels in our current fleet will be out of service at any given time, we may underestimate the time required to drydock any of our vessels or unanticipated problems may arise. If more than one of our vessels is required to be out of service at the same time, if a vessel is drydocked longer than expected or if the cost of repairs during drydocking is greater than budgeted, our cash available for distribution to unitholders could be adversely affected.

We may be unable to re-charter our vessels upon termination or expiration of their existing charters.

        We are dependent upon charters for our vessels to generate revenues and we may be adversely affected if we fail to renew or are unsuccessful in winning new charters, or if our existing charters are terminated. Our ability to re-charter our shuttle tankers following expiration of existing charters and

17


Table of Contents

the rates payable upon any renewal or replacement charters depends upon, among other things, the state of the shuttle tanker market. For example, an oversupply of shuttle tankers can significantly reduce their charter rates. A termination or renegotiation of our existing charters or a failure to secure new employment at the expiration of our current charters may have a negative effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Compliance with safety and other vessel requirements imposed by classification societies may be very costly and may adversely affect our business.

        The hull and machinery of every large, oceangoing commercial vessel must be classed by a classification society authorized by its country of registry. The classification society certifies that a vessel is safe and seaworthy in accordance with the applicable rules and regulations of the country of registry of the vessel and the International Convention for Safety of Life at Sea ("SOLAS"). All our vessels are certified either by DNV GL Group AS ("DNV GL") or by the American Bureau of Shipping ("ABS").

        As part of the certification process, a vessel must undergo annual surveys, intermediate surveys and special surveys. In lieu of a special survey, a vessel's machinery may be on a continuous survey cycle, under which the machinery would be surveyed periodically over a five-year period. Each of the vessels in our existing fleet is on a planned maintenance system approval, and as such the classification society attends onboard once every year to verify that the maintenance of the equipment onboard is done correctly. Each of the vessels in our existing fleet is required to be qualified within its respective classification society for drydocking once every five years subject to an intermediate underwater survey done using an approved diving company in the presence of a surveyor from the classification society.

        If any vessel does not maintain its class or fails any annual survey, intermediate survey or special survey, the vessel will be unable to trade between certain ports and will be unemployable. We would lose revenue while the vessel was off-hire and incur costs of compliance. This would negatively impact our revenues and reduce our cash available for distribution to unitholders.

The value of our vessels may decline, which could adversely affect our operating results.

        Vessel values for shuttle tankers can fluctuate substantially over time due to a number of different factors, including:

        If operation of a vessel is not profitable, or if we cannot redeploy a vessel at attractive rates upon termination of its charter, rather than continue to incur costs to maintain and finance the vessel, we may seek to dispose of it. Our inability to dispose of the vessel at a reasonable value could result in a loss on its sale and adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders. Additionally, lenders may accelerate loan repayments should there be a loss in the market value of our vessels. Such repayment could adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

18


Table of Contents

        Further, if we determine at any time that a vessel's future useful life and earnings require us to impair its value on our financial statements, we may need to recognize a significant charge against our earnings. We review vessels and equipment for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable, which occurs when the asset's carrying value is greater than the future undiscounted cash flows the asset is expected to generate over its remaining useful life.

Climate change and greenhouse gas restrictions may adversely impact our operations and markets.

        Due to concern over the risk of climate change, a number of countries and the International Maritime Organization (the "IMO"), the United Nations agency that regulates international shipping, have adopted, or are considering the adoption of, regulatory frameworks to reduce greenhouse gas emissions from vessels. These regulatory measures include, among others, adoption of cap and trade regimes, carbon taxes, increased efficiency standards and incentives or mandates for renewable energy. The Paris Agreement, which was announced by the Parties to the United Nations Framework Convention on Climate Change in December 2015, does not cover international shipping. However, in 2016, the IMO reaffirmed its strong commitment to continue to work to address greenhouse gas emissions from ships engaged in international trade and in 2018 adopted an initial strategy designed to reduce the emission of greenhouse gases from vessels, including short-term, mid-term and long-term candidate measures with a vision of reducing and phasing out greenhouse gas emissions from vessels as soon as possible in the 21st Century. Compliance with changes in laws, regulations and obligations relating to climate change could increase our costs related to operating and maintaining our vessels and require us to install new emission controls, acquire allowances or pay taxes related to our greenhouse gas emissions or administer and manage a greenhouse gas emissions program. Revenue generation and strategic growth opportunities may also be adversely affected.

        Adverse effects upon the oil industry relating to climate change, including growing public concern about the environmental and other impacts of climate change, may also adversely affect demand for our shuttle tanker services. Although we do not expect that demand for oil will lessen dramatically over the short term, in the long term climate change may reduce the demand for oil or increased regulation of greenhouse gases may create greater incentives for use of alternative energy sources. Any long-term material adverse effect on the oil industry could have a significant financial and operational adverse impact on our business that we cannot predict with certainty at this time.

Our international operations expose us to political, governmental and economic instability, which could harm our operations.

        Our operations are conducted in various countries, and they may be affected by economic, political and governmental conditions in the countries where we engage in business or where our vessels are registered. Any disruption caused by these factors could harm our business, including by reducing the levels of oil exploration, development and production activities in these areas. We may derive some of our revenues from shipping oil from politically unstable regions. Conflicts in these regions have included attacks on ships and other efforts to disrupt shipping. Hostilities or other political instability in regions where we operate or where we may operate could have a material adverse effect on the growth of our business, financial condition, results of operations and ability to make cash distributions to our unitholders. In addition, tariffs, trade embargoes and other economic sanctions by the United States or other countries as a result of terrorist attacks, hostilities or otherwise may limit trading activities with those countries, which could also harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders. Finally, a government could requisition one or more of our vessels, which is most likely during war or national emergency. Any such requisition would cause a loss of the vessel and/or a termination of the charter and could harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Marine transportation is inherently risky, particularly in the extreme conditions in which our vessels operate. An incident involving significant loss of product or environmental contamination by any of our vessels could harm our reputation and business.

        Vessels and their cargoes and the oil production facilities we service are at risk of being damaged or lost because of events such as:

        The Bodil Knutsen, the Hilda Knutsen, the Torill Knutsen and the Ingrid Knutsen currently operate in the North Sea. Harsh weather conditions in this region and other regions in which our vessels operate may increase the risk of collisions, oil spills or mechanical failures.

        An accident involving any of our vessels could result in any of the following:

        Any of these results could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders. In addition, any damage to, or environmental contamination involving, oil production facilities serviced could suspend that service and result in loss of revenues.

Our insurance may not be sufficient to cover losses that may occur to our property or as a result of our operations.

        The operation of shuttle tankers is inherently risky. All risks may not be adequately insured against, and any particular claim may not be paid by insurance. Any claims relating to our operations covered by insurance would be subject to deductibles, and since it is possible that a large number of claims may be brought, the aggregate amount of these deductibles could be material. Certain insurance is maintained through mutual protection and indemnity associations ("P&I clubs"), and as a member of such associations we may be required to make additional payments over and above budgeted premiums if member claims exceed association reserves

        We may be unable to procure adequate insurance at commercially reasonable rates in the future. For example, more stringent environmental regulations have led in the past to increased costs for, and in the future may result in the lack of availability of, insurance against risks of environmental damage

or pollution. A catastrophic oil spill or marine disaster could exceed the insurance, and any uninsured or underinsured loss could harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders. In addition, the insurance may be voidable by the insurers as a result of certain actions, such as vessels failing to maintain certification with applicable maritime self-regulatory organizations.

        Changes in the insurance markets attributable to terrorist attacks may also make certain types of insurance more difficult to obtain. In addition, the insurance that may be available may be significantly more expensive than existing coverage.

Terrorist attacks, piracy, increased hostilities or war could lead to further economic instability, increased costs and disruption of business.

        Terrorist attacks, piracy and the current conflicts in the Middle East, and other current and future conflicts, may adversely affect our business, financial condition, results of operations and ability to raise capital and future growth. Continuing hostilities in the Middle East may lead to additional armed conflicts or to further acts of terrorism and civil disturbance in the United States or elsewhere, which may contribute further to economic instability and disruption of oil production and distribution, which could result in reduced demand for our services.

        In addition, oil production facilities, shipyards, vessels, pipelines, oil fields or other infrastructure could be targets of future terrorist attacks and our vessels could be targets of pirates or hijackers. Any such attacks could lead to, among other things, bodily injury or loss of life, vessel or other property damage, increased vessel operational costs, including insurance costs, and the inability to transport oil to or from certain locations. Terrorist attacks, war, piracy, hijacking or other events beyond our control that adversely affect the distribution, production or transportation of oil to be shipped by us could entitle customers to terminate their charters, which would harm our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Acts of piracy on ocean-going vessels have recently increased in frequency, which could adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

        Acts of piracy have historically affected ocean-going vessels trading in regions of the world such as the South China Sea and the Gulf of Aden off the coast of Somalia. If such piracy attacks result in regions in which our vessels are deployed being named on the Joint War Committee Listed Areas, war-risk insurance premiums payable for such coverage could increase significantly and such insurance coverage might become more difficult to obtain. In addition, crew costs, including costs that may be incurred to the extent we employ onboard security guards, could increase in such circumstances. We may not be adequately insured to cover losses from these incidents, which could have a material adverse effect on us. In addition, hijacking as a result of an act of piracy against our vessels, or an increase in cost or unavailability of insurance for our vessels, could have a material adverse impact on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

Vessels transporting oil are subject to substantial environmental and other regulations, which may significantly limit operations or increase expenses.

        Our operations are affected by extensive and changing international, national and local environmental protection laws, regulations, treaties and conventions in force in international waters and the jurisdictional waters of the countries in which our vessels operate, as well as the countries of our vessels' registration, including those governing oil spills, air emissions, discharges to water and the handling and disposal of hazardous substances and wastes. Many of these requirements are designed to reduce the risk of oil spills and other pollution.

21


Table of Contents

        In addition, we believe that the heightened environmental, safety and security concerns of insurance underwriters, regulators and charterers will generally lead to additional regulatory requirements, including enhanced risk assessment and security requirements and greater inspection and safety requirements on vessels. These requirements are likely to add incremental costs to our operations and the failure to comply with these requirements may affect the ability of our vessels to obtain the required certificates for entry into the different ports where we operate and could also impact our ability to obtain insurance. We expect to incur substantial expenses in complying with these laws and regulations, including expenses for vessel modifications and changes in operating procedures.

        These requirements can affect the resale value or useful lives of our vessels, require a reduction in cargo capacity, ship modifications or operational changes or restrictions, lead to decreased availability of insurance coverage for environmental matters or result in the denial of access to certain jurisdictional waters or ports or detention in certain ports.

        Under local, national and foreign laws, as well as international treaties and conventions, we could incur material liabilities, including cleanup obligations, natural resource damage claims and fines and penalties in the event that there is a release of petroleum or hazardous substances from our vessels or otherwise in connection with our operations. We could also become subject to personal injury or property damage claims relating to the release of petroleum or hazardous substances associated with our operations. In addition, oil spills and failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions or the suspension or termination of our operations, including, in certain instances, seizure or detention of our vessels. Please read "Item 4. Information on the Partnership—Business Overview—Environmental and Other Regulation."

Exposure to currency exchange rate fluctuations results in fluctuations in cash flows and operating results.

        Our reporting currency and the functional currency of our operating subsidiaries is the U.S. Dollar. Certain of our operating subsidiaries are party to technical management agreements with KNOT Management, which govern the crew, technical and commercial management of the vessels in our fleet. Under the technical management agreements, KNOT Management is paid for reasonable direct and indirect expenses incurred in providing the services, including operating expenses relating to our fleet. A majority of the operating expenses are in currencies other than the U.S. Dollar. Fluctuating exchange rates may result in increased payments by us under the services agreements if the strength of the U.S. Dollar declines relative to such other currencies.

Many seafaring employees are covered by collective bargaining agreements and the failure to renew those agreements or any future labor agreements may disrupt operations and adversely affect our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

        A significant portion of seafarers that crew certain of our vessels are employed under collective bargaining agreements. We and our operating subsidiaries may become subject to additional labor agreements in the future. We and our operating subsidiaries may suffer labor disruptions if relationships deteriorate with the seafarers or the unions that represent them. The collective bargaining agreements may not prevent labor disruptions, particularly when the agreements are being renegotiated. Salaries for seafarers are typically renegotiated annually or bi-annually, and higher compensation levels will increase our costs of operations. Although these negotiations have not caused labor disruptions in the past, any future labor disruptions could harm our operations and could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

KNOT may on our behalf be unable to attract and retain qualified, skilled employees or crew necessary to operate our business or may have to pay substantially increased costs for its employees and crew.

        Our success depends in large part on KNOT's ability to attract, hire, train and retain highly skilled and qualified personnel. In crewing our vessels, we require technically skilled employees with specialized training who can perform physically demanding work. Competition to attract, hire, train and retain qualified crew members is intense, and crew manning costs continue to increase. If we are not able to increase our hire rates to compensate for any crew cost increases, our business, financial condition, results of operations and ability to make cash distributions to our unitholders may be adversely affected. Any inability we experience in the future to attract, hire, train and retain a sufficient number of qualified employees could impair our ability to manage, maintain and grow our business.

Our current and incoming Chief Executive Officer and Chief Financial Officer face conflicts in the allocation of their time to our business.

        John Costain, our Chief Executive Officer and Chief Financial Officer, also serves as the Finance Director for Tankers (UK) Agencies Ltd. Gary Chapman, who will become our Chief Executive Officer and Chief Financial Officer on June 1, 2019, will also serve as as the Chief Financial Officer of Biggin Hill Airport Ltd. Each of these companies conducts substantial businesses and activities of its own in which the Partnership has no economic interest. As a result, there is competition for the time and effort of Mr. Costain and Mr. Chapman.

Maritime claimants could arrest our vessels, which could interrupt our cash flow.

        If we are in default on some kinds of obligations, such as those to our lenders, crew members, suppliers of goods and services to our vessels or shippers of cargo, these parties may be entitled to a maritime lien against one or more of our vessels. In many jurisdictions, a maritime lien holder may enforce its lien by arresting a vessel through foreclosure proceedings. In a few jurisdictions, claimants could try to assert "sister ship" liability against one vessel in our fleet for claims relating to another of our vessels. The arrest or attachment of one or more of our vessels could interrupt our cash flows and require us to pay to have the arrest lifted. Under some of our present charters, if the vessel is arrested or detained as a result of a claim against us, we may be in default of our charter and the charterer may terminate the charter. This would negatively impact our revenues and reduce our cash available for distribution to unitholders.

Lack of diversification and adverse developments in the shuttle tanker market or the conventional oil tanker market would negatively impact our results.

        Although our vessels also are able to operate as conventional oil tankers, we are focused on dynamic positioning shuttle tankers. Due to our lack of diversification, any adverse development in the shuttle tanker market and/or the conventional oil tanker market could have a material adverse effect on our business, financial condition, results of operations and ability to make cash distributions to our unitholders.

If in the future our business activities involve countries, entities and individuals that are subject to restrictions imposed by the U.S. or other governments, we could be subject to enforcement action and our reputation and the market for our common units could be adversely affected.

        The tightening of U.S. sanctions in recent years has affected non-U.S. companies. In particular, sanctions against Iran have been significantly expanded. In 2012, for example, the U.S. signed into law the Iran Threat Reduction and Syria Human Rights Act of 2012 ("TRA"), which placed further restrictions on the ability of non-U.S. companies to do business or trade with Iran and Syria. A major provision in the TRA is that issuers of securities must disclose to the SEC in their annual and quarterly

23


Table of Contents

reports filed after February 6, 2013 if the issuer or "any affiliate" has "knowingly" engaged in certain activities involving Iran during the timeframe covered by the report. This disclosure obligation is broad in scope in that it requires the reporting of activity that would not be considered a violation of U.S. sanctions as well as violative conduct and is not subject to a materiality threshold. The SEC publishes these disclosures on its website and the President of the United States must initiate an investigation in response to all disclosures.

        In addition to the sanctions against Iran, the U.S. also has sanctions that target other countries, entities and individuals. These sanctions have certain extraterritorial effects that need to be considered by non-U.S. companies. It should also be noted that other governments have implemented versions of U.S. sanctions. We believe that we are in compliance with all applicable sanctions and embargo laws and regulations imposed by the U.S., the United Nations or European Union countries and intend to maintain such compliance. However, there can be no assurance that we will be in compliance in the future, particularly as the scope of certain laws may be unclear and may be subject to changing interpretations. Any such violation could result in fines or other penalties and could result in some investors deciding, or being required, to divest their interest, or not to invest, in our common units. Additionally, some investors may decide to divest their interest, or not to invest, in our common units simply because we may do business with companies that do business in sanctioned countries. Investor perception of the value of our common units may also be adversely affected by the consequences of war, the effects of terrorism, civil unrest and governmental actions in these and surrounding countries.

Failure to comply with the U.S. Foreign Corrupt Practices Act, the UK Bribery Act, the anti-corruption provisions in the Norwegian Criminal Code and other anti-bribery legislation in other jurisdictions could result in fines, criminal penalties, contract termination and an adverse effect on our business.

        We may operate in a number of countries throughout the world, including countries known to have a reputation for corruption. We are committed to doing business in accordance with applicable anti-corruption laws and have adopted a code of business conduct and ethics. We are subject, however, to the risk that we, our affiliated entities or our or their respective officers, directors, employees and agents may take actions determined to be in violation of anti-corruption laws, including the U.S. Foreign Corrupt Practices Act of 1977, the Bribery Act 2010 of the Parliament of the United Kingdom and the anti-corruption provisions of the Norwegian Criminal Code of 1902. Any such violation could result in substantial fines, sanctions, civil and/or criminal penalties, curtailment of operations in certain jurisdictions, and might adversely affect our business, results of operations or financial condition. In addition, actual or alleged violations could damage our reputation and ability to do business. Furthermore, detecting, investigating, and resolving actual or alleged violations is expensive and could consume significant time and attention of our senior management.

A cyber-attack could materially disrupt our business

        We rely on information technology systems and networks, the majority of which are provided by KNOT Management, in our operations and the administration of our business. Our operations could be targeted by individuals or groups seeking to sabotage or disrupt our information technology systems and networks, or to steal data. A successful cyber-attack could materially disrupt our operations, including the safety of our operations, or lead to unauthorized release of information or alteration of information on our systems. Any such attack or other breach of our information technology systems could have a material adverse effect on our business, results of operations, financial condition, our reputation, or cash flows. We may be required to incur additional costs to modify or enhance our information technology systems or to prevent or remediate any such attacks.

Our business is subject to complex and evolving laws, directives and regulations regarding privacy and data protection.

        We are subject to laws, directives, and regulations relating to the collection, use, retention, disclosure, security and transfer of personal data ("data protection laws"). These data protection laws, and their interpretation and enforcement, continue to evolve and may be inconsistent from jurisdiction to jurisdiction. For example, the General Data Protection Regulation ("GDPR"), which regulates the use of personally identifiable information, went into effect in the European Union ("EU") on May 25, 2018, applies globally to all of our activities conducted from an establishment in the EU, to related products and services that we offer to EU customers and to non-EU customers which offer services in the EU. Complying with the GDPR and similar emerging and changing data protection laws may cause us to incur substantial costs or require us to change our business practices. Noncompliance, or perceived noncompliance, with our legal obligations relating to data protection laws could result in penalties, fines, legal proceedings by governmental entities or others, loss of reputation, legal claims by individuals and customers and significant legal and financial exposure and could affect our ability to retain and attract customers. As noted above, we are also subject to the possibility of cyber attacks, which themselves may result in a violation of these laws.

Risks Inherent in an Investment in Us

KNOT and its affiliates may compete with us.

        Pursuant to the omnibus agreement, we entered into with KNOT at the time of our IPO (the "Omnibus Agreement"), KNOT and its controlled affiliates (other than us, our general partner and our subsidiaries) generally have agreed not to acquire, own, operate or charter certain shuttle tankers operating under charters of five years or more. The Omnibus Agreement, however, contains significant exceptions that may allow KNOT or any of its controlled affiliates to compete with us, which could harm our business. Please read "Item 7. Major Unitholders and Related Party Transactions—Related Party Transactions—Omnibus Agreement—Noncompetition."

Unitholders have limited voting rights, and our partnership agreement restricts the voting rights of Norwegian Resident Holders and unitholders owning more than 4.9% of our common units.

        Unlike the holders of common stock in a corporation, holders of common units have only limited voting rights on matters affecting our business. We hold a meeting of the limited partners every year to elect one or more members of our board of directors and to vote on any other matters that are properly brought before the meeting. Common unitholders are entitled to elect only four of the seven members of our board of directors. The elected directors are elected on a staggered basis and generally serve for four-year terms. Our general partner in its sole discretion appoints the remaining three directors and sets the terms for which those directors serve. Our partnership agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting our unitholders' ability to influence the manner or direction of management. Unitholders have no right to elect our general partner, and our general partner may not be removed except by a vote of the holders of at least 662/3% of the outstanding common units, including any units owned by our general partner and its affiliates, voting together as a single class.

        Our partnership agreement further restricts unitholders' voting rights by providing that Norwegian Resident Holders are not eligible to vote in the election of elected directors. Further, if any person or group owns beneficially more than 4.9% of any class of units then outstanding, any such units owned by that person or group in excess of 4.9% may not be voted on any matter and are not considered to be outstanding when sending notices of a meeting of unitholders, calculating required votes (except for purposes of nominating a person for election to our board of directors), determining the presence of a

25


Table of Contents

quorum or for other similar purposes, unless required by law. The voting rights of any unitholders not entitled to vote on a specific matter are effectively redistributed pro rata among the other common unitholders. Our general partner, its affiliates and persons who acquire common units with the prior approval of our board of directors are not subject to the 4.9% limitation except with respect to voting their common units in the election of the elected directors.

KNOT and its affiliates own a substantial interest in us and have conflicts of interest and limited fiduciary and contractual duties to us and our common unitholders, which may permit them to favor their own interests to the detriment of our unitholders.

        As of April 10, 2019, KNOT owned 26.2% of our common units and owned and controlled our general partner, which owns a 1.85% general partner interest in us and 0.3% of our common units. Certain of our directors are directors of KNOT or its affiliates, and, as such, they have fiduciary duties to KNOT or its affiliates that may cause them to pursue business strategies that disproportionately benefit KNOT or its affiliates or which otherwise are not in the best interests of us or our unitholders. Conflicts of interest may arise between KNOT and its affiliates (including our general partner), on the one hand, and us and our unitholders, on the other hand. As a result of these conflicts, our general partner and its affiliates may favor their own interests over the interests of our unitholders. Please read "—Our partnership agreement limits our general partner's and our directors' fiduciary duties to our unitholders and restricts the remedies available to unitholders for actions taken by our general partner or our directors." These conflicts include, among others, the following situations:

26


Table of Contents

        Although a majority of our directors have been elected by common unitholders, our general partner has substantial influence on decisions made by our board of directors. Please read "Item 7. Major Unitholders and Related Party Transactions."

Our partnership agreement limits our general partner's and our directors' fiduciary duties to our unitholders and restricts the remedies available to unitholders for actions taken by our general partner or our directors.

        Our partnership agreement provides that our general partner irrevocably delegates to our board of directors the authority to oversee and direct our operations, management and policies on an exclusive basis, and such delegation is binding on any successor general partner of the Partnership. Our partnership agreement also contains provisions that reduce the standards to which our general partner and directors would otherwise be held by Marshall Islands law. For example, our partnership agreement:

        In order to become a limited partner of our partnership, a common unitholder is required to agree to be bound by the provisions in our partnership agreement, including the provisions discussed above.

        Our partnership agreement provides that our general partner delegates all its management activities in relation to us to our board of directors, and arrangements are in place such that any activities that would otherwise constitute regulated activities under the Financial Services and Markets Act 2000 (Regulated Activities Order) 2001 were they to be performed in the United Kingdom (and that would not fall within a suitable exemption) are performed outside of the United Kingdom.

27


Table of Contents

However, there can be no assurance that this will not change (deliberately or otherwise) over time, and there is no current intention for our general partner, us or any of our subsidiaries to seek authorization from the Financial Conduct Authority in the United Kingdom, which would be required for any person to lawfully carry out such regulated activities in the United Kingdom.

Fees and cost reimbursements, which affiliates of KNOT determine for services provided to us and our subsidiaries, are substantial, payable regardless of our profitability and reduce our cash available for distribution to our unitholders.

        Pursuant to technical management agreements, our subsidiaries that own vessels operating under time charters pay fees for services provided to them by KNOT Management and reimburse KNOT Management for all expenses incurred on their behalf. These fees and expenses include all costs and expenses incurred in providing the crew, technical and commercial management of the vessels in our fleet to our subsidiaries. Additionally our subsidiaries that own vessels operating under bareboat charters have entered into management and administration agreements with either KNOT Management or KNOT Management Denmark pursuant to which these companies provide general monitoring services for the vessels in exchange for an annual fee.

        In addition, pursuant to an administrative services agreement, KNOT UK provides us with certain administrative services. KNOT UK is permitted to subcontract certain of the administrative services provided to us under this agreement to KOAS UK, KOAS and KNOT Management. We reimburse KNOT UK, and KNOT UK reimburses KOAS UK, KOAS and KNOT Management, as applicable, for their reasonable costs and expenses incurred in connection with the provision of the services subcontracted to KOAS UK, KOAS and KNOT Management under the administrative services agreement. In addition, KNOT UK pays to KOAS UK, KOAS and KNOT Management, as applicable, a service fee in U.S. Dollars equal to 5% of the costs and expenses incurred in connection with providing services.

        For a description of the technical management agreements, management and administration agreements and the administrative services agreement, please read "Item 7. Major Unitholders and Related Party Transactions." The fees and expenses payable pursuant to the technical management agreements, management and administration agreements and the administrative services agreement are payable without regard to our business, results of operation and financial condition. The payment of fees to and the reimbursement of expenses of affiliates of KNOT could adversely affect our ability to pay cash distributions to our unitholders.

Our partnership agreement contains provisions that may have the effect of discouraging a person or group from attempting to remove our current management or our general partner, and even if public unitholders are dissatisfied, they are unable to remove our general partner without KNOT's consent, unless KNOT's ownership interest in us is decreased, all of which could diminish the trading price of our common units.

        Our partnership agreement contains provisions that may have the effect of discouraging a person or group from attempting to remove our current management or our general partner.

28


Table of Contents

        The effect of these provisions may be to diminish the price at which the common units trade.

The control of our general partner may be transferred to a third party without unitholder consent.

        Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets without the consent of our unitholders. In addition, our partnership agreement does not restrict the ability of the members of our general partner from transferring their respective membership interests in our general partner to a third party.

Substantial future sales of our common units or the issuance of additional preferred units in the public market could cause the price of our common units to fall.

        The market price of our common units could decline due to sales of a large number of units, or the issuance of debt securities or warrants, in the market, or the perception that these sales could occur. These sales could also make it more difficult for us to sell equity securities in the future at a time and price that we deem appropriate to raise funds through future offerings of common units.

        We have granted registration rights to KNOT and certain of its affiliates. These unitholders have the right, subject to some conditions, to require us to file registration statements covering any of our common or other equity securities owned by them or to include those securities in registration statements that we may file for ourselves or other unitholders. As of April 10, 2019, KNOT and our general partner owned 26.5% of the common units and all of the incentive distribution rights. We have also entered into a registration rights agreement with the holders of the Series A Preferred Units,

29


Table of Contents

pursuant to which we filed a registration statement to register resales of the common units underlying the Series A Preferred Units. Following their registration and sale, these securities will become freely tradable. By exercising their registration rights and selling a large number of common units or other securities, our securityholders with registration rights could cause the price of our common units to decline.

Our common units are subordinated to our existing and future indebtedness and our Series A Preferred Units.

        Our common units are equity interests in us and do not constitute indebtedness. The common units rank junior to all indebtedness and other non-equity claims on us with respect to the assets available to satisfy claims, including a liquidation of the Partnership. Additionally, holders of the common units are subject to the prior distribution and liquidation rights of the holders of the Series A Preferred Units and any other preferred units we may issue in the future.

        As long as our outstanding Series A Preferred Units remain outstanding, distribution payments relating to our common units are prohibited under our partnership agreement until all accrued and unpaid distributions are paid on the Series A Preferred Units.

KNOT, as the holder of all of the incentive distribution rights, may elect to cause us to issue additional common units to it in connection with a resetting of the target distribution levels related to its incentive distribution rights without the approval of the conflicts committee of our board of directors or holders of our common units. This may result in lower distributions to holders of our common units in certain situations.

        KNOT, as the holder of all of the incentive distribution rights, has the right, at a time when it has received incentive distributions at the highest level to which it is entitled (48.0%) for each of the prior four consecutive fiscal quarters, to reset the initial cash target distribution levels at higher levels based on the distribution at the time of the exercise of the reset election. Following a reset election by KNOT, the minimum quarterly distribution will be reset to an amount equal to the average cash distribution per common unit for the two fiscal quarters immediately preceding the reset election (such amount is referred to as the "reset minimum quarterly distribution"), and the target distribution levels will be reset to correspondingly higher levels based on the same percentage increases above the reset minimum quarterly distribution.

        In connection with resetting these target distribution levels, KNOT will be entitled to receive a number of common units equal to that number of common units whose aggregate quarterly cash distributions equaled the average of the distributions to it on the incentive distribution rights in the prior two quarters. We anticipate that KNOT would exercise this reset right in order to facilitate acquisitions or internal growth projects that would not be sufficiently accretive to cash distributions per common unit without such conversion; however, it is possible that KNOT could exercise this reset election at a time when it is experiencing, or may be expected to experience, declines in the cash distributions it receives related to its incentive distribution rights and may therefore desire to be issued our common units, rather than retain the right to receive incentive distributions based on the initial target distribution levels. As a result, a reset election may cause our common unitholders to experience dilution in the amount of cash distributions that they would have otherwise received had we not issued additional common units to KNOT in connection with resetting the target distribution levels related to KNOT's incentive distribution rights. Please read "Item 8. Financial Information—Consolidated Statements and Other Financial Information—Our Cash Distribution Policy—Incentive Distribution Rights."

Table of Contents

We may issue additional equity securities, including a limited amount of securities senior to the common units, without the approval of our unitholders, which would dilute their ownership interests.

        We may, without the approval of our unitholders, issue an unlimited number of additional common units. In addition, we may issue units that are senior to the common units in right of distribution, liquidation and voting, provided that the aggregate amount of our Series A Preferred Units and any other securities on parity with the Series A Preferred Units, pro forma for such issuance, does not exceed 33.33% of the book value of the sum of our then outstanding aggregate amount of parity securities and junior securities (including the common units). The consent of the holders of the Series A Preferred Units will be necessary for us to issue any parity securities (or securities senior to our Series A Preferred Units) in excess of such pro forma book value.

        The issuance by us of additional common units or other equity securities of equal or senior rank will have the following effects:

A substantial number of our common units may be issued upon conversion of our Series A Preferred Units or as redemption payments in respect of our Series A Preferred Units, which issuances could reduce the value of our common units.

        Our Series A Preferred Units will be convertible, under certain circumstances, at the then applicable conversion rate, which will be subject to adjustment under certain circumstances. The conversion rate will be redetermined on a quarterly basis, such that the conversion rate will be equal to $24.00 (the "Issue Price") divided by the product of (x) the book value per common unit at the end of the immediately preceding quarter (pro-forma for per unit cash distributions payable with respect to such quarter) multiplied by (y) the quotient of (i) the Issue Price divided by (ii) the book value per common unit on the initial issuance date of the Series A Preferred Units.

        The Series A Preferred Units are generally convertible, at the option of the holders of the Series A Preferred Units, into common units at the then applicable conversion rate. In addition, we may redeem the Series A Preferred Units at any time before February 2, 2027 at the redemption price applicable on any such redemption date, provided, however, that upon notice from us to the holders of Series A Preferred Units or our intention to redeem, such holders may elect, instead, to convert their Series A Preferred Units into common units at the then applicable conversion rate. In addition, subject to certain conditions, we may convert the Series A Preferred Units into common units at the then applicable conversion rate. Upon a change of control of the Partnership, the holders of Series A Preferred Units may require us to redeem the Series A Preferred Units, in cash, at 100% of the Issue Price. Further, the holders of Series A Preferred Units may cause us to redeem the Series A Preferred Units on February 2, 2027 in, at our option, (i) cash at a price equal to 70% of the Issue Price or (ii) common units such that each Series A Preferred Unit receives common units worth 80% of the Issue Price. The value (and, therefore, the number) of the common units to be delivered pursuant thereto will be determined based on the volume-weighted average trading price, as adjusted for splits, combinations and other similar transactions, of our common units as reported on the NYSE for the 30-trading day period ending on the fifth trading day immediately prior to the redemption date.

        If a substantial portion of the Series A Preferred Units are converted into common units or redeemed under certain circumstances, common unitholders could experience significant dilution. Furthermore, if holders of such Series A Preferred Units were to dispose of a substantial portion of

31


Table of Contents

these common units in the public market following such a conversion, whether in a single transaction or series of transactions, it could adversely affect the market price for our common units. These sales, or the possibility that these sales may occur, could make it more difficult for us to sell our common units in the future.

        The number of our common units issuable upon conversion or redemption under certain circumstances of the Series A Preferred Units will be impacted by, among other things, the level of our quarterly cash distributions, as the conversion rate is redetermined each quarter, based on the pro forma per unit cash distributions we make on our common units (as described above) and the market price of our common units. Accordingly, the number of common units issuable upon conversion or redemption under certain circumstances could be substantial, especially during periods of significant declines in market prices of our common units or if we experience certain events, such as, among other things, a decline in the value of our vessels that results in an impairment or write-down of the value of our vessels or a write-off of any goodwill, decline in the fair value of our derivative instruments, change in accounting principle that results in a decline in our book value, or other event that results in a decline in our book value.

        The issuance of common units upon conversion or redemption under certain circumstances of our Series A Preferred Units may have the following effects:

        The market price of our common units is likely to be influenced by the Series A Preferred Units. For example, the market price of our common units could become more volatile and could be depressed by:

Our Series A Preferred Units have rights, preferences and privileges that are not held by, and are preferential to the rights of, holders of our common units.

        Our Series A Preferred Units rank senior to all our common units with respect to distribution rights and liquidation preference. These preferences could adversely affect the market price for our common units or could make it more difficult for us to sell our common units in the future.

        In addition, distributions on the Series A Preferred Units accrue and are cumulative. Our obligation to pay distributions on our Series A Preferred Units, or on the common units issued following conversion of such Series A Preferred Units, could impact our liquidity and reduce the amount of cash flow available for working capital, capital expenditures, growth opportunities, acquisitions, and other general partnership purposes. Our obligations to the holders of Series A Preferred Units could also limit our ability to obtain additional financing or increase our borrowing costs, which could have an adverse effect on our financial condition.

32


Table of Contents

In establishing cash reserves, our board of directors may reduce the amount of cash available for distribution to our unitholders.

        Our partnership agreement requires our board of directors to deduct from operating surplus cash reserves that it determines are necessary to fund our future operating expenditures. These reserves also affect the amount of cash available for distribution to our unitholders. As described above in "—Risks Inherent in Our Business—We must make substantial capital expenditures to maintain the operating capacity of our fleet, which reduces cash available for distribution. In addition, each quarter we are required to deduct estimated maintenance and replacement capital expenditures from operating surplus, which may result in less cash available to unitholders than if actual maintenance and replacement capital expenditures were deducted," our partnership agreement requires our board of directors each quarter to deduct from operating surplus estimated maintenance and replacement capital expenditures, as opposed to actual maintenance and replacement capital expenditures, which could reduce the amount of available cash for distribution. The amount of estimated maintenance and replacement capital expenditures deducted from operating surplus is subject to review and change by our board of directors at least once a year, provided that any change must be approved by the conflicts committee of our board of directors.

Our general partner has a limited call right that may require our unitholders to sell their common units at an undesirable time or price.

        If at any time our general partner and its affiliates own more than 80.0% of the common units, our general partner has the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price not less than the then-current market price of our common units. Our general partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon the exercise of this limited call right. As a result, our unitholders may be required to sell their common units at an undesirable time or price and may not receive any return on their investment. Our unitholders may also incur a tax liability upon a sale of their units.

        As of April 10, 2019, KNOT and our general partner owned 26.5% of our common units.

Our unitholders may not have limited liability if a court finds that unitholder action constitutes control of our business.

        As a limited partner in a partnership organized under the laws of the Marshall Islands, our unitholders could be held liable for our obligations to the same extent as a general partner if our unitholders participate in the "control" of our business. Our general partner generally has unlimited liability for the obligations of the Partnership, such as its debts and environmental liabilities, except for those contractual obligations of the Partnership that are expressly made without recourse to our general partner. In addition, the limitations on the liability of holders of limited partner interests for the obligations of a limited partnership have not been clearly established in some jurisdictions in which we do business.

We can borrow money to pay distributions, which would reduce the amount of credit available to operate our business.

        Our partnership agreement allows us to make working capital borrowings to pay distributions. Accordingly, if we have available borrowing capacity, we can make distributions on all our units even though cash generated by our operations may not be sufficient to pay such distributions. Any working capital borrowings by us to make distributions reduces the amount of working capital borrowings we can make for operating our business. For more information, please read "Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources."

Increases in interest rates may cause the market price of our common units to decline.

        An increase in interest rates may cause a corresponding decline in demand for equity investments in general, and in particular for yield-based equity investments such as our common units. Any such increase in interest rates or reduction in demand for our common units resulting from other relatively more attractive investment opportunities may cause the trading price of our common units to decline.

We are exposed to market risks relating to the announced phase-out of the London Interbank Offered Rate ("LIBOR")

        We are exposed to a market risk relating to increases in interest rates because the amounts borrowed under our existing loan and credit facilities bear interest at rates based on LIBOR. On July 27, 2017, the United Kingdom Financial Conduct Authority ("FCA"), which regulates LIBOR, announced that it intends to stop persuading or compelling banks to submit rates for the calculation of LIBOR to the administrator of LIBOR after 2021 ("FCA Announcement"). The FCA Announcement indicates that the continuation of LIBOR on the current basis is not guaranteed after 2021. Significant increases in LIBOR or uncertainty surrounding its phase out after 2021 could adversely affect our business, financial condition, operating results and cash flows. We use interest rate swaps to reduce our exposure to interest rate risk and hedge a portion of our outstanding indebtedness. There is no assurance that our derivative contracts will provide adequate protection against adverse changes in interest rates or that our bank counterparties will be able to perform their obligations.

Unitholders may have liability to repay distributions.

        Under some circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under the Marshall Islands Limited Partnership Act (the "Marshall Islands Act"), we may not make a distribution to our unitholders if the distribution would cause our liabilities, other than liabilities to partners on account of their partnership interest and liabilities for which the recourse of creditors is limited to specified property of ours, to exceed the fair value of our assets, except that the fair value of property that is subject to a liability for which the recourse of creditors is limited will be included in our assets only to the extent that the fair value of that property exceeds that liability. Marshall Islands law provides that for a period of three years from the date of the impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Marshall Islands law will be liable to the limited partnership for the distribution amount. Assignees who become substituted limited partners are liable for the obligations of the assignor to make contributions to the limited partnership that are known to the assignee at the time it became a limited partner and for unknown obligations if the liabilities could be determined from our partnership agreement.

We have been organized as a limited partnership under the laws of the Marshall Islands, which does not have a well-developed body of partnership law.

        Our partnership affairs are governed by our partnership agreement and by the Marshall Islands Act. The provisions of the Marshall Islands Act resemble provisions of the limited partnership laws of a number of states in the United States, most notably Delaware. The Marshall Islands Act also provides that it is to be applied and construed to make it, with respect to the subject matter thereof, uniform with the laws of the State of Delaware and, for non-resident limited partnerships such as ours, so long as it does not conflict with the Marshall Islands Act or decisions of the High and Supreme Courts of the Marshall Islands, the non-statutory law (or case law) of the State of Delaware is adopted as the law of the Marshall Islands. There have been, however, few, if any, court cases in the Marshall Islands interpreting the Marshall Islands Act, in contrast to Delaware, which has a fairly well-developed body of case law interpreting its limited partnership statute. Accordingly, we cannot predict whether Marshall Islands courts would reach the same conclusions as the courts in Delaware. For example, the rights of

34


Table of Contents

our unitholders and the fiduciary responsibilities of our general partner under Marshall Islands law are not as clearly established as under judicial precedent in existence in Delaware. As a result, unitholders may have more difficulty in protecting their interests in the face of actions by our general partner and its officers and directors than would unitholders of a similarly organized limited partnership in the United States.

Because we and KNOT UK are Marshall Islands entities, our operations may be subject to economic substance requirements of the European Union, which could harm our business.

        On December 5, 2017, following an assessment of the tax policies of various countries by the Code of Conduct Group for Business Taxation of the European Union (the "COCG"), the Council of the European Union (the "Council") approved and published Council conclusions containing a list of "non-cooperative jurisdictions" for tax purposes (the "2017 Conclusions"). On March 12, 2019, the Council adopted a revised list of non-cooperative jurisdictions (the "2019 Conclusions"). In the 2019 Conclusions, the Republic of the Marshall Islands, among others, was placed by the E.U. on its list of non-cooperative jurisdictions for tax purposes for failing to implement certain commitments previously made to the E.U. by the agreed deadline. E.U. member states have agreed upon a set of measures, which they can choose to apply against the listed countries, including increased monitoring and audits, withholding taxes, special documentation requirements and anti-abuse provisions. The European Commission has stated it will continue to support member states' efforts to develop a more coordinated approach to sanctions for the listed countries in 2019. E.U. legislation prohibits E.U. funds from being channeled or transited through entities in non-cooperative jurisdictions.

        We are a Marshall Islands partnership and KNOT UK is a Marshall Islands limited liability company. At present, the impact of being included on the list of non-cooperative jurisdictions for tax purposes is unclear. Certain jurisdictions have enacted or may enact economic substance laws and regulations in response to the listing and the Marshall Islands may enact similar laws and regulations with which we may be obligated to comply. If we fail to comply with our obligations under any such laws and regulations, we could be subject to financial penalties and spontaneous disclosure of information to foreign tax officials, or could be struck from the register of companies.

        We do not know: if the E.U. will remove the Marshall Islands from the list of non-cooperative jurisdictions; what actions the Marshall Islands may take, if any, to remove itself from the list; how quickly the E.U. would react to any changes in legislation of the Marshall Islands; or how E.U. banks or other counterparties will react while we or KNOT UK remain as entities organized and existing under the laws of the Marshall Islands. The effect of the E.U. list of non-cooperative jurisdictions, and any noncompliance by us with any legislation adopted by the Marshall Islands to achieve removal from the list, could have a material adverse effect on our business, financial conditions and operating results.

Because we are organized under the laws of the Marshall Islands, it may be difficult to serve us with legal process or enforce judgments against us, our directors or our management.

        We are organized under the laws of the Marshall Islands, and substantially all of our assets are located outside of the United States. In addition, our general partner is a Marshall Islands limited liability company, and our directors and officers generally are or will be non-residents of the United States, and all or a substantial portion of the assets of these non-residents are located outside the United States. As a result, it may be difficult or impossible for our unitholders to bring an action against us or against these individuals in the United States if our unitholders believe that their rights have been infringed under securities laws or otherwise. Even if our unitholders are successful in bringing an action of this kind, the laws of the Marshall Islands and of other jurisdictions may prevent or restrict our unitholders from enforcing a judgment against our assets or the assets of our general partner or our directors or officers.

Tax Risks

        In addition to the following risk factors, you should read "Item 4. Information on the Partnership—Business Overview—Taxation of the Partnership" and "Item 10. Additional Information—Taxation" for a more complete discussion of the expected material U.S. federal and non-U.S. income tax considerations relating to us and the ownership and disposition of our common units.

We are subject to taxes, which reduces our cash available for distribution to our unitholders.

        We and our subsidiaries may be subject to tax in the jurisdictions in which we are organized or operate, reducing the amount of cash available for distribution. In computing our tax obligations in these jurisdictions, we are required to take various tax accounting and reporting positions on matters that are not entirely free from doubt and for which we have not received rulings from the governing authorities. We cannot assure you that, upon review of these positions, the applicable authorities will agree with our positions. A successful challenge by a tax authority could result in additional tax imposed on us or our subsidiaries, further reducing the cash available for distribution. In addition, changes in our operations or ownership could result in additional tax being imposed on us or our subsidiaries in jurisdictions in which operations are conducted.

A change in tax laws in any country in which we operate could adversely affect us.

        Tax laws and regulations are highly complex and subject to interpretation. Consequently, we and our subsidiaries are subject to changing tax laws, treaties and regulations in and between countries in which we operate. Our income tax expense is based on our interpretation of the tax laws in effect at the time the expense was incurred. A change in tax laws, treaties or regulations, or in the interpretation thereof, could result in a materially higher tax expense or a higher effective tax rate on our earnings. Such changes may include measures enacted in response to the ongoing initiatives in relation to fiscal legislation at an international level, such as the Action Plan on Base Erosion and Profit Shifting of the Organization for Economic Co-operation and Development.

U.S. tax authorities could treat us as a "passive foreign investment company," which would have adverse U.S. federal income tax consequences to U.S. unitholders.

        A non-U.S. entity treated as a corporation for U.S. federal income tax purposes will be treated as a "passive foreign investment company" (a "PFIC") for U.S. federal income tax purposes if at least 75% of its gross income for any taxable year consists of "passive income" or at least 50% of the average value of its assets produce, or are held for the production of, "passive income." For purposes of these tests, "passive income" includes dividends, interest, gains from the sale or exchange of investment property, and rents and royalties other than rents and royalties that are received from unrelated parties in connection with the active conduct of a trade or business. For purposes of these tests, income derived from the performance of services does not constitute "passive income." U.S. unitholders of a PFIC are subject to a disadvantageous U.S. federal income tax regime with respect to the income derived by the PFIC, the distributions they receive from the PFIC, and the gain, if any, they derive from the sale or other disposition of their interests in the PFIC.

        Based on our current and projected method of operation, we believe that we were not a PFIC for any prior taxable year, and we expect that we will not be treated as a PFIC for the current or any future taxable year. We believe that more than 25% of our gross income for each taxable year was or will be non-passive income, and more than 50% of the average value of our assets for each such year was or will be held for the production of non-passive income. This belief is based on certain valuations and projections regarding our income and assets, and its validity is based on the accuracy of such valuations and projections. While we believe these valuations and projections to be accurate, the

36


Table of Contents

shipping market is volatile, and no assurance can be given that they will continue to be accurate at any time in the future.

        Moreover, there are legal uncertainties involved in determining whether the income derived from time-chartering activities constitutes rental income or income derived from the performance of services. In Tidewater Inc. v. United States, 565 F.3d 299 (5th Cir. 2009), the United States Court of Appeals for the Fifth Circuit (the "Fifth Circuit") held that income derived from certain time-chartering activities should be treated as rental income rather than services income for purposes of a provision of the Internal Revenue Code of 1986, as amended (the "Code"), relating to foreign sales corporations. In that case, the Fifth Circuit did not address the definition of passive income or the PFIC rules; however, the reasoning of the case could have implications as to how the income from a time charter would be classified under such rules. If the reasoning of this case were extended to the PFIC context, the gross income we derive or are deemed to derive from our time-chartering activities may be treated as rental income, and we would likely be treated as a PFIC. In published guidance, the Internal Revenue Service (the "IRS") stated that it disagreed with the holding in Tidewater and specified that time charters similar to those at issue in the case should be treated as service contracts. We have not sought, and we do not expect to seek, an IRS ruling on the treatment of income generated from our time-chartering activities. As a result, the IRS or a court could disagree with our position. No assurance can be given that this result will not occur. In addition, although we intend to conduct our affairs in a manner to avoid, to the extent possible, being classified as a PFIC with respect to any taxable year, we cannot assure you that the nature of our operations will not change in the future, or that we will not be a PFIC in the future. If the IRS were to find that we are or have been a PFIC for any taxable year (and regardless of whether we remain a PFIC for any subsequent taxable year), our U.S. unitholders would face adverse U.S. federal income tax consequences. Please read "Item 10. Additional Information—Taxation—U.S. Federal Income Taxation of U.S. Holders—PFIC Status and Significant Tax Consequences" for a more detailed discussion of the U.S. federal income tax consequences to U.S. unitholders if we are treated as a PFIC.

We may have to pay tax on U.S. source income, which would reduce our cash flow.

        Under the Code, U.S. source gross transportation income generally is subject to a 4% U.S. federal income tax without allowance for deduction of expenses, unless an exemption from tax applies under a tax treaty or Section 883 of the Code and the Treasury Regulations promulgated thereunder. U.S. source gross transportation income consists of 50% of the gross shipping income that is attributable to transportation that begins or ends, but that does not both begin and end, in the United States.

        We expect that our vessel-owning subsidiaries will qualify for an exemption from U.S. tax on any U.S. source gross transportation income under the Convention Between the United States of America and the Kingdom of Norway with Respect to Taxes on Income and Property (the "U.S.-Norway Tax Treaty"), and we intend to take this position for U.S. federal income tax purposes. However, if we acquire interests in vessel-owning subsidiaries in the future that are not Norwegian residents for purposes of the U.S.-Norway Tax Treaty, U.S. source gross transportation income earned by those subsidiaries would generally be subject to a 4% U.S. federal income tax unless the exemption under Section 883 of the Code applied. In general, the Section 883 exemption provides that if a non-U.S. corporation satisfies the requirements of Section 883 of the Code and the Treasury Regulations thereunder, it will not be subject to the 4% U.S. federal income tax referenced above on its U.S. source gross transportation income. The Section 883 exemption does not apply to income attributable to transportation that begins and ends in the United States.

        The vessels in our fleet do not currently engage in transportation that begins and ends in the United States, and we do not expect that our subsidiaries will in the future earn income from such transportation. If, notwithstanding this expectation, our subsidiaries earn income in the future from transportation that begins and ends in the United States, that income would not be exempt from U.S.

Table of Contents

federal income tax under Section 883 of the Code and may not be exempt from U.S. federal income tax under the U.S.-Norway Tax Treaty and therefore may be subject to net income tax in the United States (currently at a 21% rate).

        The imposition of U.S. federal income tax on our income could have a negative effect on our business and would result in decreased earnings available for distribution to our unitholders.

Our unitholders may be subject to income tax in one or more non-U.S. jurisdictions as a result of owning our common units if, under the laws of any such jurisdiction, we are considered to be carrying on business there. Such laws may require our unitholders to file a tax return with, and pay taxes to, those jurisdictions.

        We conduct our affairs and cause each of our subsidiaries to operate its business in a manner that minimizes income taxes imposed upon us and our subsidiaries. Furthermore, we conduct our affairs and cause each of our subsidiaries to operate its business in a manner that minimizes the risk that unitholders may be treated as having a permanent establishment or taxable presence in a jurisdiction where we or our subsidiaries conduct activities simply by virtue of their ownership of our common units. However, because we are organized as a partnership, there is a risk in some jurisdictions, including Norway, that our activities or the activities of our subsidiaries may rise to the level of a taxable presence that is attributed to our unitholders for tax purposes. We have obtained confirmation from the United Kingdom HM Revenue & Customs that unitholders should not be treated as trading in the United Kingdom merely by virtue of their ownership of our common units. If our unitholders are attributed such a taxable presence in a jurisdiction, our unitholders may be required to file a tax return with, and to pay tax in, that jurisdiction based on our unitholders' allocable share of our income. In addition, we may be required to obtain information from our unitholders in the event a tax authority (including in the United Kingdom) requires such information to submit a tax return. We may be required to reduce distributions to our unitholders on account of any tax withholding obligations imposed upon us by that jurisdiction in respect of such allocation to our unitholders. The United States may not allow a tax credit for any foreign income taxes that our unitholders directly or indirectly incur by virtue of an investment in us.

Item 4.    Information on the Partnership

General

        KNOT Offshore Partners LP is a publicly traded limited partnership formed on February 21, 2013 to own, operate and acquire shuttle tankers under long-term charters, which we define as charters of five years or more. On April 18, 2013, we completed our initial public offering ("IPO") of 8,567,500 common units. In connection with our IPO, through KNOT UK, a 100% owned limited liability company formed under the laws of the Marshall Islands, the Partnership acquired a 100% ownership interest in KNOT Shuttle Tankers AS, which as of February 27, 2013 directly or indirectly owned (1) 100% of Knutsen Shuttle Tankers XII KS, the owner of the Recife Knutsen and the Fortaleza Knutsen, (2) 100% of Knutsen Shuttle Tankers XII AS, the general partner of Knutsen Shuttle Tankers XII KS, and (3) the Windsor Knutsen and the Bodil Knutsen and all of their related charters, inventory and long-term debt. In establishing the new KNOT Shuttle Tankers AS structure, KNOT formed three new Norwegian subsidiaries, which acquired 90% of Knutsen Shuttle Tankers XII KS, 100% of the Windsor Knutsen and 100% of the Bodil Knutsen, respectively.

General

        We were formed to own and operate shuttle tankers under long-term charters. Our primary business objective is to increase quarterly distributions per unit over time by growing our business through accretive acquisitions of shuttle tankers and by chartering our vessels pursuant to long-term charters with high quality customers that generate long-term stable cash flows. All of the vessels in our current fleet are chartered to Equinor, Transpetro, Repsol, Shell, ExxonMobil, Galp and ENI under long-term charters. Our charters have an average remaining term of 3.4 years as of March 31, 2019 (including guaranteed option periods).

        Since our IPO, we have increased our quarterly distribution from $0.375 per unit to $0.52 per unit for the quarter ended December 31, 2018.

        We intend to leverage the relationships, expertise and reputation of KNOT, a leading independent owner and operator of shuttle tankers, to pursue potential growth opportunities and to attract and retain high-quality, creditworthy customers. As of April 10, 2018, KNOT and our general partner owned our general partner interest, all of our incentive distribution rights and 26.5% of our common units. KNOT intends to utilize us as its primary growth vehicle to pursue the acquisition of long-term, stable cash-flow-generating shuttle tankers.

Business Strategies

        Our primary business objective is to increase quarterly distributions per unit over time by executing the following strategies:

        We can provide no assurance, however, that we will be able to implement our business strategies described above. For further discussion of the risks that we face, please read "Item 3. Key Information—Risk Factors."

Shuttle Tanker Market

        A shuttle tanker is a specialized vessel designed to transport crude oil and condensates from offshore oil field installations to onshore terminals and refineries. Shuttle tankers are equipped with sophisticated loading systems and dynamic positioning systems that allow the vessels to load cargo safely and reliably from oil field installations, even in harsh weather conditions.

        Shuttle tankers are often described as "floating pipelines," because these vessels typically shuttle oil from offshore installations to onshore facilities in much the same way a pipeline would transport oil along the ocean floor. Shuttle tankers can be either purpose-built or converted from existing conventional oil tankers.

        The advantages of shuttle tankers as compared to pipelines include:

        Shuttle tankers primarily differ from conventional oil tankers based on two significant features. First, shuttle tankers are fitted with position-keeping equipment enabling them to remain in a position without the assistance of tugs or mooring to installations. Second, shuttle tankers are equipped with bow-loading equipment and, in some cases, also fitted with equipment for submerged turret loading. Conventional oil tankers load from an offshore field installation usually through a taut hawser (mooring line onboard the discharging unit) operation and/or with tug assistance. In certain cases, dedicated shuttle tanker newbuilds are required to service the specific requirements of oil fields and installations. At times, conventional oil tankers can be converted to shuttle tankers after a substantial upgrade and investment in equipment.

        A time charter is a contract for the use of a specified vessel for a fixed period of time at a specified daily rate. Under time charters, the shipowner is responsible for providing crewing and other vessel operating services, the cost of which is included in the daily rate, while the customer is responsible for substantially all of the voyage expenses. A bareboat charter is a contract for the use of a specified vessel for a fixed period of time at a specified daily or annual rate. Under bareboat charters, the shipowner is not responsible for providing crewing or other operational services, while the customer is responsible for all vessel operating expenses and voyage expenses. In addition, bareboat charters also provide that the shipowner is responsible for repairs or renewals occasioned by latent defects in the vessel existing at the time of delivery, provided such defects have manifested themselves within 18 months after delivery. However, under bareboat charters, the customer is responsible for ordinary repair and maintenance, including drydocking.

        The initial term for a time charter or bareboat charter commences upon the vessel's delivery to the customer. Our time charters include options, exercisable by the customer, to extend the charter's initial term. Under the time charters, the customer may also extend the term for periods in which the vessel is off-hire, as described below. Customers under each of our time charters and bareboat charters have rights to terminate the charter prior to expiration of the original or any extended term in specified circumstances.

        Hire rate refers to the basic payment from the customer for the use of the vessel. Under our time charters, the majority of hire rate is payable monthly in advance, in U.S. Dollars. The hire rate payable under our time charters is either a fixed amount for the firm period of the time charter with escalations to be made in case of option periods or increases annually based on a fixed percentage increase or fixed schedule, in order to enable us to offset expected increases in operating costs. Under our time charters, hire rate payments may be reduced if the vessel does not perform to certain of its specifications, such as if the average vessel speed falls below a guaranteed speed or the amount of fuel consumed to power the vessel under normal circumstances exceeds a guaranteed amount.

        The hire rate payable under our bareboat charters is fixed and payable monthly in advance, in U.S. Dollars. The customer is also required to maintain minimum levels of insurance to protect the interests of the customer, the shipowner and mortgagees, if any.

        Under our time charters, when the vessel is off-hire, or not available for service, the customer generally is not required to pay the hire rate, and the shipowner is responsible for all costs. Prolonged off-hire may lead to a termination of the time charter. A vessel generally will be deemed off-hire if there is a loss of time due to, among other things:

        Our bareboat charters do not contain provisions for off-hire.

        Under our time charters, the shipowner is responsible for the technical management of the vessel and for maintaining the vessel, periodic drydocking, cleaning and painting and performing work required by regulations. KNOT Management and KNOT Management Denmark provide these services to our subsidiaries for all our vessels under time charters. Please read "Item 7. Major Unitholders and Related Party Transactions—Related Party Transactions." Under our bareboat charters, the shipowner is not responsible for providing crewing or other operational services and the customer is responsible for all vessel operating expenses and voyage expenses. However, Transpetro has elected to subcontract the technical operation and management of the Fortaleza Knutsen, the Recife Knutsen, the Dan Cisne and the Dan Sabia to an affiliate of KNOT.

        Each of our time charters and bareboat charters terminates automatically if the applicable vessel is lost or missing. In addition, under certain circumstances, the customer may have an option to terminate the time charter if the vessel is requisitioned by any government for a period of time in excess of the time period specified in the time charter or if at any time the shipowner is in default under the time charter. Under the bareboat charters, the charter is deemed terminated as of the date of any compulsory acquisition of the vessel or requisition for title by any governmental or other competent authority. In addition, the shipowner is generally entitled to suspend performance (but with the continuing accrual to its benefit of hire rate payments and default interest) and terminate the charter if the customer defaults in its payment obligations. Under the time charters and bareboat charters, either party may also terminate the charter in the event of war in specified countries.

        However, under the bareboat charters, in the event of war, hire shall continue to be paid in accordance with the charter until redelivery. In addition, under the bareboat charters, the shipowner has the right to terminate the charter if the customer (1) does not take immediate steps to have the necessary repairs done within a reasonable time or (2) does not arrange and keep certain insurance.

Competition

        The shuttle tanker industry is capital intensive and operational expertise is critical, which create high barriers to entry. The shuttle tanker industry is viewed as an integral part of offshore oil production creating a market with few alternative suppliers and therefore a low risk of substitution. A company with a solid track record, knowledge of the market and an experienced, well-trained crew is preferred to a new entrant since the cost and impact of vessel downtime is significant for the customer. Furthermore, the systems in place for operational procedures, such as offshore loading and vetting, have significant value when negotiating contracts with new and existing customers.

        According to Fearnresearch, as of April 1, 2019, there were approximately 88 vessels in the world shuttle tanker fleet (including 15 newbuilds on order). Teekay Offshore Partners L.P. is the largest owner in the shuttle tanker market with approximately 32 shuttle tankers (including 6 newbuilds on order). KNOT is the second largest owner of shuttle tankers with 32 shuttle tankers (including our vessels and 3 newbuilds on order). American Eagle Tankers (AET) is the third largest owner of shuttle tankers with 11 vessels (including 7 newbuilds on order). Petrobras, which owns two vessels, employs a total of 24 shuttle tankers (including 3 newbuilds on order) through long-term bareboat and time charters. There are other shuttle tanker owners in the industry, but most of such owners have a limited fleet size and have chartered vessels out for the long term.

Classification, Inspection and Maintenance

        Every large, commercial seagoing vessel must be "classed" by a classification society. The classification society certifies that the vessel is "in class," signifying that the vessel has been built and

44


Table of Contents

maintained in accordance with the rules of the classification society. In most cases, the classification society is authorized by the flag state to certify that the vessels also comply with applicable rules and regulations of the vessel's country of registry and the international conventions of which that country is a member. In addition, where surveys are required by international conventions and corresponding laws and ordinances of a flag state, the classification society may undertake them on application or by official order, acting on behalf of the authorities concerned. The classification society also undertakes on request other surveys and checks that are required by regulations and requirements of the flag state. These surveys are subject to agreements made in each individual case and/or to the regulations of the country concerned. For maintenance of the class, regular and extraordinary surveys of hull, machinery, including the electrical plant, and any special equipment classed are required to be performed by the classification society as follows:

        All of the vessel's areas subject to survey as defined by the classification society are required to be surveyed at least once per class period, unless shorter intervals between surveys are prescribed elsewhere. The period between two subsequent surveys of each area must not exceed five years.

        A vessel's underwater parts are required to be inspected every 24 to 36 months by the classification society. Drydocking of vessels is done, at the minimum, every 60 months until the vessel is 15 years old and every 30 months thereafter. If any defects are found, the classification surveyor will issue a condition of class that must be rectified by the shipowner.

        Most insurance underwriters make it a condition for insurance coverage that a vessel be certified as "in class" by a classification society that is a member of the International Association of Classification Societies. All of our vessels have been awarded International Safety Management certification and are certified as being "in class" by DNV GL or ABS, the Norwegian and American classification societies, respectively. All new and secondhand vessels that we purchase must be certified prior to their delivery under the standard purchase contracts and memoranda of agreement. If the vessel is not certified on the date of closing, we will have no obligation to take delivery of the vessel.

        KNOT, through certain of its subsidiaries, operates as our ship manager, and carries out inspections of the ships on a regular basis, both at sea and while the vessels are in port, as well as carrying out inspections and ship audits to verify conformity with managers' reports. The results of these inspections result in a report containing recommendations for improvements to the overall condition of the vessel, maintenance, safety and crew welfare. Based in part on these evaluations, we create and implement a program of continual maintenance and improvement for our vessels and their systems.

Safety, Management of Ship Operations and Administration

        Safety and environmental compliance is our top operational priority. Our vessels are operated in a manner intended to protect the safety and health of our employees, the general public and the environment. We actively manage the risks inherent in our business and are committed to eliminating incidents that threaten the safety and integrity of our vessels, such as groundings, fires, collisions and petroleum spills. We are also committed to reducing emissions and waste generation. We have established key performance indicators to facilitate regular monitoring of our operational performance. We set targets on an annual basis to drive continuous improvement, and we review performance indicators monthly to determine if remedial action is necessary to reach our targets. KNOT's shore staff performs a full range of technical, commercial and business development services for us. This staff also provides administrative support to our operations in finance, accounting and human resources.

        KNOT, through certain of its subsidiaries, assists us and our operating subsidiaries in managing our ship operations. DNV GL, a Norwegian classification society, has approved KNOT's safety management system, which has been implemented on all our ships, as complying with the IMO's International Management Code for the Safe Operation of Ships and Pollution Prevention (the "ISM Code"), International Standards Organization ("ISO") 9001 for Quality Assurance, ISO 14001 for Environment Management Systems and OHSAS 18001, for Occupational Health and Safety Management System. As part of KNOT's ISM Code compliance, all the vessels' safety management certificates are being maintained through ongoing internal audits performed by KNOT's certified internal auditors and external audits performed by DNV GL or the respective flag state. Subject to satisfactory completion of these internal and external audits, certification is valid for five years.

        KNOT provides, through certain of its subsidiaries, expertise in various functions critical to the operations of our operating subsidiaries. We believe this arrangement affords a safe, efficient and cost-effective operation. KNOT's subsidiaries also provide to us access to human resources, financial and other administrative functions pursuant to technical management agreements. Please read "Item 7. Major Unitholders and Related Party Transactions—Related Party Transactions—Technical Management Agreements."

        Critical ship management functions that are provided by KNOT or its subsidiaries through various of its offices around the world include:

46


Table of Contents

        These functions are supported by onboard and onshore systems for maintenance, inventory, purchasing and budget management. In addition, KNOT's day-to-day focus on cost control will be applied to our operations. We believe that the adoption of common standards should also result in operational efficiencies, including with respect to crew training and vessel management, equipment operation and repair, and spare parts ordering.

Risk of Loss, Insurance and Risk Management

        The operation of any vessel, including shuttle tankers, has inherent risks. These risks include mechanical failure, personal injury, collision, property loss, vessel or cargo loss or damage and business interruption due to political circumstances in foreign countries or hostilities. In addition, there is always an inherent possibility of marine disaster, including explosion, spills and other environmental mishaps, and the liabilities arising from owning and operating vessels in international trade. We believe that our present insurance coverage is adequate to protect us against the accident-related risks involved in the conduct of our business and that we maintain appropriate levels of environmental damage and pollution insurance coverage consistent with standard industry practice. However, not all risks can be insured, and there can be no guarantee that any specific claim will be paid, or that we will always be able to obtain adequate insurance coverage at reasonable rates.

        We have obtained hull and machinery insurance on all our vessels to insure against marine and war risks, which include the risks of damage to our vessels, salvage or towing costs, and also insure against actual or constructive total loss of any of our vessels. However, our insurance policies contain deductible amounts for which we are responsible. We have also arranged additional total loss coverage for each vessel. This coverage, which is called hull interest and freight interest coverage, provides us additional coverage in the event of the total loss or the constructive total loss of a vessel.

        We have also obtained loss of hire insurance to protect us against loss of income in the event one of our vessels cannot be employed due to damage that is covered under the terms of our hull and machinery insurance. Under our loss of hire policies, our insurer will pay us the hire rate agreed in respect of each vessel for each day, in excess of a certain number of deductible days, for the time that the vessel is out of service as a result of damage, for a maximum of 180 days. The number of deductible days for the vessels in our fleet is 14 days per vessel.

        All of our hull and machinery, hull interest and freight interest and loss of hire insurance policies are written on the Norwegian Marine Insurance Plan ("NMIP"), which through the hull and maintenance coverage also offers comprehensive collision liability coverage of up to the insured hull and maintenance value of the vessel. NMIP is based on an "all risk principle" and offers what is considered to be the most comprehensive insurance obtainable in any of the world's marine markets today. The agreed deductible on each vessel averages $150,000 for the shuttle tankers in our fleet.

        Protection and indemnity insurance, which covers our third-party legal liabilities in connection with our shipping activities, is provided by a P&I club. This includes third-party liability and other expenses related to the injury or death of crew members, passengers and other third-party persons, loss or damage to cargo, claims arising from collisions with other vessels or from contact with jetties or wharves and other damage to other third-party property, including pollution arising from oil or other substances, and other related costs, including wreck removal. Subject to the capping discussed below, our coverage, except for pollution, is unlimited.

        Our current protection and indemnity insurance coverage for pollution is $1 billion per vessel per incident. The 13 P&I clubs that comprise the International Group of Protection and Indemnity Clubs insure approximately 90% of the world's commercial tonnage and have entered into a pooling agreement to reinsure each association's liabilities. Each P&I club has capped its exposure in this pooling agreement so that the maximum claim covered by the pool and its reinsurance would be approximately $1 billion per accident or occurrence. We are a member of Norwegian P&I Club Skuld.

47


Table of Contents

As a member of these P&I clubs, we are subject to a call for additional premiums based on the clubs' claims record, as well as the claims record of all other members of the P&I clubs comprising the International Group. However, our P&I clubs have reinsured the risk of additional premium calls to limit our additional exposure. This reinsurance is subject to a cap, and there is the risk that the full amount of the additional call would not be covered by this reinsurance.

        The insurers providing the covers for hull and machinery, hull interest and freight interest, protection and indemnity and loss of hire insurances have confirmed that they will consider the shuttle tankers as vessels for the purpose of providing insurance.

        We use in our operations KNOT's risk management program that includes, among other things, risk analysis tools, maintenance and assessment programs, a seafarers competence training program, seafarers workshops and membership in emergency response organizations. We benefit from KNOT's commitment to safety and environmental protection as certain of its subsidiaries assist us in managing our vessel operations.

        KNOT has achieved certification under the standards reflected in ISO 9001 for quality assurance, ISO 14001 for environment management systems and the ISM Code on a fully integrated basis.

Environmental and Other Regulation

        Our business and the operation of our vessels are significantly affected by international conventions and national, state and local laws and regulations in the jurisdictions in which our vessels operate, as well as in the country or countries of their registration. Because these conventions, laws and regulations change frequently, we cannot predict the ultimate cost of compliance or their impact on the resale price or useful life of our vessels. While we believe that we are in substantial compliance with the current environmental laws and regulations that apply to our operations, there is no assurance that such compliance or compliance with amended or newly adopted laws and regulations can be maintained in the future. Additional conventions, laws, and regulations may be adopted that could limit our ability to do business or increase the cost of our doing business and that may materially adversely affect our operations. We are required by various governmental and quasi-governmental agencies to obtain permits, licenses and certificates with respect to our operations. Subject to the discussion below and to the fact that the kinds of permits, licenses and certificates required for the operations of the vessels we own depend on a number of factors, we believe that we will be able to continue to obtain all permits, licenses and certificates material to the conduct of our operations.

        The IMO is the United Nations' agency responsible for developing measures to improve the safety and security of international shipping and to prevent marine pollution from ships. IMO regulations relating to pollution prevention for oil tankers have been adopted by many of the jurisdictions in which our tanker fleet operates. Under IMO regulations and subject to limited exceptions, a tanker must be of double-hull construction, a mid-deck design with double-side construction or another approved design ensuring the same level of protection against oil pollution. All of our tankers are double-hulled.

        Many countries, but not the United States, have ratified and follow the liability regime adopted by the IMO and set out in the International Convention on Civil Liability for Oil Pollution Damage, 1969, as updated by the 1992 Protocol (the "CLC"). Under this convention, a vessel's registered owner is strictly liable for pollution damage caused in the territorial waters of a contracting state by discharge of persistent oil (e.g. crude oil, fuel oil, heavy diesel oil or lubricating oil), subject to certain defenses. The right to limit liability to specified amounts that are periodically revised is forfeited under the CLC when the spill is caused by the owner's actual fault or when the spill is caused by the owner's intentional or

48


Table of Contents

reckless conduct. Vessels trading to contracting states must provide evidence of insurance covering the limited liability of the owner. In jurisdictions where the CLC has not been adopted, various legislative regimes or common law governs, and liability is imposed either on the basis of fault or in a manner similar to the CLC. IMO regulations also include SOLAS, including amendments to SOLAS implementing the International Security Code for Ports and Ships (the "ISPS"), the ISM Code and the International Convention on Load Lines of 1966. The IMO Marine Safety Committee has also published guidelines for vessels with dynamic positioning systems, which would apply to shuttle tankers. SOLAS provides rules for the construction of and equipment required for commercial vessels and includes regulations for safe operation. Flag states that have ratified the CLC generally utilize the classification societies, which have incorporated SOLAS requirements into their class rules, to undertake surveys to confirm compliance.

        SOLAS and other IMO regulations concerning safety, including those relating to treaties on training of shipboard personnel, lifesaving appliances, radio equipment and the global maritime distress and safety system, are applicable to our operations. Non-compliance with IMO regulations, including SOLAS, the ISM Code, and the ISPS, or the requirements for shuttle tankers under their flag regulations, may subject us to increased liability or penalties, may lead to decreases in available insurance coverage for affected vessels and may result in the denial of access to or detention in some ports. For example, the U.S. Coast Guard and European Union (the "EU") authorities have indicated that vessels not in compliance with the ISM Code will be prohibited from trading in U.S. and EU ports.

        The requirements contained in the ISM Code govern our operations. Among other requirements, the ISM Code requires vessel operators to obtain a safety management certification for each vessel they manage, evidencing the shipowner's development and maintenance of an extensive safety management system. Each of the existing vessels in our fleet is currently ISM Code-certified, and we expect to obtain safety management certificates for each newbuild upon delivery.

        The International Labour Organization (the "ILO") is a specialized agency of the United Nations with headquarters in Geneva, Switzerland. The ILO has adopted the Maritime Labor Convention 2006 (the "MLC 2006") to improve safety onboard merchant vessels. A Maritime Labor Certificate and a Declaration of Maritime Labor Compliance is required to ensure compliance with the MLC 2006 for all ships above 500 gross tons in international trade. On August 20, 2012, the required number of countries ratified the MCL 2006 and it came into force on August 20, 2013. The MLC 2006 requires us to develop new procedures to ensure full compliance with its requirements. Each of the existing vessels in our fleet is currently MLC 2006-certified, and we expect to obtain MLC 2006 certificates for each newbuild upon delivery.

        The IMO has adopted the International Convention for the Prevention of Pollution from Ships ("MARPOL"), including Annex VI to MARPOL that sets limits on sulfur dioxide and nitrogen oxide emissions from ship exhausts and prohibits deliberate emissions of ozone depleting substances. Annex VI applies to all ships and, among other things, imposes a global cap on the sulfur content of fuel oil and allows for specialized areas to be established internationally with even more stringent controls on sulfur emissions. For vessels 400 gross tons and greater, platforms and drilling rigs, Annex VI imposes various survey and air pollution prevention certification requirements. Moreover, Annex VI regulations impose progressively stricter limitations on sulfur emissions from ships. As of January 2, 2015, these limitations require that fuels of vessels in covered Emission Control Areas ("ECAs") contain no more than 0.1% sulfur. For non-ECA areas, the capped sulfur limitations decrease progressively until they reach the global limit of 0.5% that applies on and after January 1, 2020. MARPOL Annex VI also establishes new tiers of stringent nitrogen oxide emissions standards for new marine engines, depending on their date of installation. All of our vessels are in compliance with these requirements.

49


Table of Contents

        In addition, there are several other regulatory requirements to use low sulfur fuel or restrict or regulate emissions from vessels that are either already in force or are upcoming. The EU Directive 33/2005 requiring the use of low sulfur fuel came into force on January 1, 2010. Under this legislation, vessels are required to burn fuel with sulfur content below 0.1% while berthed or anchored in an EU port. The California Air Resources Board requires vessels to burn fuel with 0.1% sulfur content or less within 24 nautical miles of California as of January 1, 2014. Currently, the only grade of fuel meeting 0.1% sulfur content requirement is low sulfur marine gas oil. All of our vessels are able to comply with applicable low sulfur fuel requirements.

        The IMO has negotiated international conventions that impose liability for oil pollution and other environmental harms in international waters and the territorial waters of the signatory to such conventions such as the International Convention for the Control and Management of Ships' Ballast Water and Sediments (the "BWM Convention"). The BWM Convention's implementing regulations call for a phased introduction of mandatory ballast water exchange requirements (which began in 2009), to be replaced in time with a requirement for mandatory ballast water treatment. The BWM Convention entered into force on September 8, 2017. As referenced below, the U.S. Coast Guard issued new ballast water management rules on March 23, 2012. Under the requirements of the BWM Convention for units with ballast water capacity more than 5,000 cubic meters that were constructed in 2011 or before, ballast water management exchange or treatment were accepted until 2016. From 2016 (or not later than the first intermediate or renewal survey after 2016), only ballast water treatment will be accepted by the BWM Convention. Installation of ballast water treatment systems will be needed on our vessels. Although the cost to comply with IMO ballast water treatment regulations for our vessels is difficult to estimate, it is anticipated to be approximately $1.5-$2.0 million per vessel for the Fortaleza Knutsen, Recife Knutsen, Bodil Knutsen, Windsor Knutsen, Carmen Knutsen, Dan Cisne and Dan Sabia. The Anna Knutsen, the Brasil Knutsen, the Lena Knutsen, the Torill Knutsen, the Hilda Knutsen, the Ingrid Knutsen, the Raquel Knutsen the Vigdis Knutsen and the Tordis Knutsen have all installed IMO approved ballast water treatment system.

        The International Convention on Civil Liability for Bunker Oil Pollution 2001 (the "Bunker Convention") provides a liability, compensation and compulsory insurance system to protect and reimburse the victims of oil pollution damage in jurisdictional waters of ratifying states caused by discharges of bunker fuel. The Bunker Convention became effective in 2008 and imposes strict liability on shipowners for certain pollution damage. Registered owners of any seagoing vessel and seaborne craft over 1,000 gross tonnage, of any type whatsoever, and registered in a signatory state (a "State Party"), or entering or leaving a port in the territory of a State Party, will be required to maintain insurance that meets the requirements of the Bunker Convention and to obtain a certificate issued by a State Party attesting that such insurance is in force. The state-issued certificate must be carried onboard at all times. P&I clubs in the International Group issue the required Bunkers Convention "Blue Cards" to enable signatory states to issue certificates. All of our vessels have received "Blue Cards" from their P&I club and are in possession of a CLC State-issued certificate attesting that the required insurance coverage is in force.

        The IMO continues to review and introduce new regulations. It is impossible to predict what additional regulations, if any, may be passed by the IMO and what effect, if any, such regulation may have on our operations.

        In waters of the EU, our vessels are subject to regulation EU-level directives implemented by the various nations through laws and regulations adopting these requirements. These laws and regulations prescribe measures to prevent pollution, protect the environment, support maritime safety and set out civil and criminal penalties that are being progressively incorporated into domestic legislation. For instance, the EU has adopted legislation (EU Directive 2009/16/EC) that: bans from EU waters

50


Table of Contents

manifestly sub-standard vessels (defined as vessels that have been detained twice by EU port authorities, in the preceding two years, after July 2003); creates obligations on the part of EU member port states to inspect at least 24% of vessels using these ports annually; provides for increased surveillance of vessels posing a high risk to maritime safety or the marine environment; and provides the EU with greater authority and control over classification societies, including the ability to seek to suspend or revoke the authority of negligent societies. If deficiencies are found that are clearly hazardous to safety, health or the environment, the state is required to detain the vessel until the deficiencies are addressed. Member states are also required to implement a system of penalties for breaches of these standards. EU Directive 2009/16/EC introduced a harmonized and coordinated regime for port state control inspections and from January 1, 2011 an on-line register to make public both the poorly performing shipping companies (who will attract more intensive and coordinated inspections) and those with good records. Like the IMO, the EU has adopted regulations phasing out single-hull tankers. All of our tankers are double-hulled.

        Several regulatory requirements to use low sulfur fuel are in force or upcoming. See discussion of "low sulfur fuel" regulations above.

        The EU is currently considering other proposals to further regulate vessel operations. We cannot predict what additional legislation or regulations, if any, may be promulgated by the EU or any other country or authority. The trend, however, is towards increasing regulation and our expectation is that requirements will become more extensive and more stringent over time. If more stringent requirements are put in effect in the future, they may require, individually or in the aggregate, significant expenditures and could increase our operating costs, potentially affecting financial performance.

        Our shuttle tankers currently operate in the North Sea and Brazil.

        In addition to the regulations imposed by the IMO and the EU, countries having jurisdiction over North Sea areas impose further regulatory requirements on operations in those areas, including Maritime and Coastguard Agency regulations in the United Kingdom and Norwegian Maritime Directorate regulations in Norway. These regulatory requirements, together with additional requirements imposed by operators in North Sea oil fields, require that we make further expenditures for sophisticated equipment, reporting and redundancy systems on the shuttle tankers and for the training of seagoing staff. Additional regulations and requirements may be adopted or imposed that could limit our ability to do business or further increase the cost of doing business in the North Sea.

        In Norway, the Norwegian Pollution Control Authority requires the installation of volatile organic compound emissions ("VOC") control equipment, on most shuttle tankers serving the Norwegian continental shelf. The license holders of the oil field are responsible for the costs to ensure that shuttle tankers operating in the field are using appropriate VOC control equipment. In recent contracts, the charterers have requested owners to install such equipment against an increase in the hire rate. We have installed the VOC control equipment required to operate on the Norwegian continental shelf in each of the Fortaleza Knutsen, the Recife Knutsen, the Bodil Knutsen, the Windsor Knutsen, the Hilda Knutsen, the Torill Knutsen and the Ingrid Knutsen.

        In Brazil, the field operator and in most cases Petrobras where it is involved are required to establish internal procedures to manage pollution risks, which must be approved by the competent environmental authority. Brazilian environmental law includes international treaties and conventions to which Brazil is a party, as well as federal, state and local laws, regulations and permit requirements related to the protection of health and the environment. The petroleum industry in Brazil is subject to extensive regulations by several governmental agencies, including the National Agency of Petroleum,

51


Table of Contents

the Brazilian Navy and the Brazilian Institute of the Environment and Renewable Natural Resources. Failure to comply may subject us to administrative, criminal and civil liability, with strict liability in administrative and civil cases.

        In the United States, federal and state laws and regulations that require vessel owners and operators to obtain and maintain specified permits or governmental approvals; control the discharge of materials into the environment; remove and cleanup materials that may harm the environment; and otherwise comply with regulations intended to protect the environment. Vessel operations are subject to the jurisdiction of the U.S. Coast Guard, the National Transportation Safety Board, the U.S. Customs and Border Protection, the Department of Interior, the Bureau of Ocean Energy Management, and the Bureau of Safety and Environmental Enforcement, as well as classification societies such as the American Bureau of Shipping. The United States has enacted an extensive regulatory and liability regime for the protection and cleanup of the environment from oil spills, including discharges of oil cargoes, bunker fuels or lubricants, primarily through the Oil Pollution Act of 1990 ("OPA 90") and the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA").

        Oil Pollution Act and CERCLA.    CERCLA applies to the discharge of "hazardous substances" rather than "oil" and imposes strict joint and several liability upon the owners, operators or bareboat charterers of vessels for cleanup costs and damages arising from discharges of hazardous substances. We believe that petroleum products should not be considered hazardous substances under CERCLA, but additives to oil or lubricants used on vessels might fall within its scope.

        OPA 90 affects all owners, bareboat charterers and operators whose vessels trade to the United States or its territories or possessions or whose vessels operate in U.S. waters, which include the U.S. territorial sea and 200-mile exclusive economic zone around the United States.

        Under OPA 90, vessel owners, operators and bareboat charterers are "responsible parties" and are jointly, severally and strictly liable (unless the oil spill results solely from the act or omission of a third party, an act of God or an act of war and the responsible party reports the incident and reasonably cooperates with the appropriate authorities) for all containment and cleanup costs and other damages arising from discharges or threatened discharges of oil from their vessels. These other damages are defined broadly to include:

        OPA 90 limits the liability of responsible parties in an amount it periodically updates. The liability limits do not apply if the incident was proximately caused by violation of applicable U.S. federal safety, construction or operating regulations, including IMO conventions to which the United States is a signatory, or by the responsible party's gross negligence or willful misconduct, or if the responsible party fails or refuses to report the incident or to cooperate and assist in connection with the oil removal activities. Liability under CERCLA is also subject to limits unless the incident is caused by gross negligence, willful misconduct or a violation of certain regulations. We currently maintain for each of our vessel's pollution liability coverage in the maximum coverage amount of $1 billion per

52

incident. A catastrophic spill could exceed the coverage available, which could harm our business, financial condition and results of operations.

        Under OPA 90, with limited exceptions, all newly built or converted tankers delivered after January 1, 1994 and operating in U.S. waters must be double-hulled. All of our tankers are double-hulled. OPA 90 also requires owners and operators of vessels to establish and maintain with the U.S. Coast Guard evidence of financial responsibility in an amount at least equal to the relevant limitation amount for such vessels under the statute. The U.S. Coast Guard has implemented regulations requiring that an owner or operator of a fleet of vessels must demonstrate evidence of financial responsibility in an amount sufficient to cover the vessel in the fleet having the greatest maximum limited liability under OPA 90 and CERCLA. Evidence of financial responsibility may be demonstrated by insurance, surety bond, self-insurance, guaranty or an alternate method subject to approval by the U.S. Coast Guard. Under the self-insurance provisions, the shipowner or operator must have a net worth and working capital, measured in assets located in the United States against liabilities located anywhere in the world, that exceeds the applicable amount of financial responsibility. We have complied with the U.S. Coast Guard regulations by using self-insurance for certain vessels and obtaining financial guaranties from a third party for the remaining vessels. If vessels in our fleet trade to the United States in the future, we expect to provide guaranties through self-insurance or obtain guaranties from third-party insurers.

        OPA 90 and CERCLA permit individual U.S. states to impose their own liability regimes with regard to oil or hazardous substance pollution incidents occurring within their boundaries, and some states have enacted legislation providing for unlimited strict liability for spills. Several coastal states, such as California, Washington and Alaska require state-specific evidence of financial responsibility and vessel response plans. We intend to comply with all applicable regulations in the ports where our vessels call.

        Owners or operators of vessels, including tankers operating in U.S. waters are required to file vessel response plans with the U.S. Coast Guard, and their tankers are required to operate in compliance with their U.S. Coast Guard approved plans. Such response plans must, among other things:

        In addition, we conduct regular oil spill response drills in accordance with the guidelines set out in OPA 90. The U.S. Coast Guard has announced it intends to propose similar regulations requiring certain vessels to prepare response plans for the release of hazardous substances. OPA 90 and CERCLA do not preclude claimants from seeking damages resulting from the discharge of oil and hazardous substances under other applicable law, including maritime tort law. The application of this doctrine varies by jurisdiction.

        Clean Water Act.    The United States Clean Water Act ("CWA") prohibits the discharge of oil or hazardous substances in United States navigable waters unless authorized by a permit or exemption, and imposes strict liability in the form of penalties for unauthorized discharges. The CWA also imposes substantial liability for the costs of removal, remediation and damages and complements the remedies available under OPA 90 and CERCLA. The U.S. Environmental Protection Agency (the "EPA") has enacted rules governing the regulation of ballast water discharges and other discharges incidental to the normal operation of vessels within U.S. waters. The EPA authorized these incidental discharges pursuant to a permit the EPA designated as the Vessel General Permit for Discharges Incidental to the

53


Table of Contents

Normal Operation of Vessels (the "VGP"), which incorporated the current U.S. Coast Guard requirements for ballast water management as well as supplemental ballast water requirements, and includes limits applicable to 26 specific discharge streams, such as deck runoff, bilge water and gray water.

        The EPA updated the VGP in 2013 to incorporate numeric effluent limits for ballast water expressed as the maximum concentration of living organisms in ballast water, as opposed to the prior non-numeric requirements. These requirements correspond with the IMO's requirements under the BWM Convention, as discussed above. The permit also contains maximum discharge limitations for biocides and residuals. The numeric effluent limits in the new VGP will not apply to all vessels. Those that will be required to comply with the numeric limits will do so under a staggered implementation schedule. Certain existing vessels must achieve the numeric effluent limits for ballast water by the first drydocking after January 1, 2014 or January 1, 2016, depending on the vessel size. Newbuilds are subject to the numeric limits upon the effective date of the new permit. Vessels that have deferred deadlines for meeting the numeric standards must meet Best Management Practices, which are substantially similar to the requirements under the previous VGP.

        The VGP includes a tiered requirement for obtaining coverage based on the size of the vessel and the amount of ballast water carried. Vessels that are 300 gross tons or larger and have the capacity to carry more than eight cubic meters of ballast water must submit notices of intent ("NOIs") to receive permit coverage between six and nine months after the permit's issuance date. Vessels that do not need to submit NOIs are automatically authorized under the permit. In December 2018, the Vessel Incidental Discharge Act ("VIDA") was signed into law and restructured the EPA and the U.S. Coast Guard programs for regulating incidental discharges from vessels. Rather than requiring CWA permits, the discharges will be regulated under a new CWA Section 312(p) establishing Uniform National Standards for Discharges Incidental to Normal Operation of Vessels. Under VIDA, VGP provisions and existing U.S. Coast Guard regulations will be phased out over a period of approximately four years and replaced with National Standards of Performance ("NSPs") to be developed by EPA and implemented and enforced by the U.S. Coast Guard. The scheduled expiration date of the 2013 VGP was December 18, 2018, but under VIDA the provisions of the VGP will remain in place until the new regulations are in place.

        In addition to the requirements in the VGP (to be replaced by the NSPs established under VIDA), vessel owners and operators must meet 25 sets of state-specific requirements under the CWA's § 401 certification process. Because the CWA § 401 process allows tribes and states to impose their own requirements for vessels operating within their waters, vessels operating in multiple jurisdictions could face potentially conflicting conditions specific to each jurisdiction that they travel through.

        While we do not believe that the costs associated with complying with the existing VGP permits and the NSPs that will be promulgated, including meeting related treatment requirements, will be material, it is difficult to predict the overall impact of CWA requirements on our business at this stage. In addition, state-specific requirements under the CWA's § 401 and any similar restrictions enacted in the future could increase our costs of operating in the relevant waters.

        National Invasive Species Act ("NISA").    In March 2012, the U.S. Coast Guard issued a final rule establishing standards for the allowable concentration of living organisms in ballast water discharged in U.S. waters and requiring the phase-in of U.S. Coast Guard approved ballast water management systems. The rule went into effect in June 2012 and set ballast water discharge standards for vessels calling on U.S. ports and intending to discharge ballast water equivalent to those set in IMO's BWM Convention. The final rule requires that ballast water discharge have no more than ten living organisms per milliliter for organisms between ten and 50 micrometers in size. For organisms larger than 50 micrometers, the discharge can have no more than ten living organisms per cubic meter of

discharge. New ships constructed on or after December 1, 2013 must comply with these ballast water treatment standards and some existing ships must comply by their first drydock after January 1, 2014.

        Clean Air Act.    The United States Clean Air Act requires the EPA to promulgate standards applicable to emissions of volatile organic compounds and other air contaminants. Our vessels are subject to vapor control and recovery requirements for certain cargoes in regulated port areas and emission standards for so-called "Category 3" marine diesel engines operating in U.S. waters. The marine diesel engine emission standards are equivalent to those adopted set forth in Annex VI to MARPOL. Compliance with these standards may cause us to incur costs to install control equipment on our vessels in the future.

        Trends in Environmental Regulation in the United States.    Numerous governmental agencies issue regulations to implement and enforce the laws of the applicable jurisdiction, which often involve lengthy permitting procedures, impose difficult and costly compliance measures, particularly in ecologically sensitive areas, and subject operators to substantial administrative, civil and criminal penalties or may result in injunctive relief for failure to comply. Some of these laws contain criminal sanctions in addition to civil penalties. Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent and costly compliance or limit contract drilling opportunities, including changes in response to a serious marine incident that results in significant oil pollution or otherwise causes significant adverse environmental impact, such as the April 2010 Macondo well blowout incident, could adversely affect our financial results. Although significant capital expenditures may be required to comply with these governmental laws and regulations, such compliance has not materially adversely affected our earnings or competitive position. We believe that we are currently in compliance in all material respects with the environmental regulations to which we are subject.

        We may also be affected by or subject to permitting and other requirements under a variety of other environmental laws not discussed above, such as the Endangered Species Act, Marine Mammal Protection Act and National Environmental Policy Act.

        In February 2005, the Kyoto Protocol to the United Nations Framework Convention on Climate Change (the "Kyoto Protocol") entered into force. Pursuant to the Kyoto Protocol, adopting countries are required to implement national programs to reduce emissions of greenhouse gases ("GHGs"). Currently, the emissions of greenhouse gases from international shipping are not subject to the Kyoto Protocol or to the more recently announced Paris Agreement.

        On July 15, 2011, the IMO approved mandatory measures to reduce emissions of greenhouse gases from international shipping. The amendments to Annex VI to MARPOL for the prevention of air pollution from ships add a new Chapter 4 to Annex VI on energy efficiency requiring the Energy Efficiency Design Index ("EEDI") for new ships, and the Ship Energy Efficiency Management Plan ("SEEMP") for all ships. The regulations apply to all ships of 400 gross tonnage and above and are entered into force on January 1, 2013. These rules will likely affect the operations of vessels that are registered in countries that are signatories to Annex VI to MARPOL or vessels that call upon ports located within such countries. The IMO also adopted a mandatory data collection system requirement in October 2016 ("IMO DCS") that requires ships of 5000 gross tonnage and above to record and report their fuel oil consumption, indirectly addressing carbon dioxide emissions data. The requirement was entered into force on March 1, 2018. These requirements could cause us to incur additional compliance costs.

        The IMO is also considering the development of a market-based mechanism for greenhouse gas emissions from ships. At the October 2016 Marine Environmental Protection Committee ("MEPC") session, the IMO adopted a roadmap for developing a comprehensive IMO strategy on reduction of

55


Table of Contents

GHG emissions. In April 2018, the MEPC adopted an initial strategy designed to reduce the emission of greenhouse gases from vessels, including short-term, mid-term and long-term candidate measures with a vision of reducing and phasing out greenhouse gas emissions from vessels as soon as possible in the 21st Century. The EU has indicated that it intends to implement regulation in an effort to limit emissions of greenhouse gases from vessels if such emissions are not regulated through the IMO.

        In the United States, the EPA issued an "endangerment finding" regarding greenhouse gases under the Clean Air Act. While this finding in itself does not impose any requirements on our industry, it authorizes the EPA to regulate directly greenhouse gas emissions through a rule-making process. The EPA has already been petitioned by the California Attorney General to regulate greenhouse gas emissions from oceangoing vessels. In addition, climate change initiatives have been or are being considered in the United States Congress and by individual states. In June 2013, the European Commission developed a strategy to integrate maritime emissions into the overall European Union strategy to reduce greenhouse gas emissions. In accordance with this strategy, in April 2015 the European Parliament and Council adopted regulations (EU Directive 2015/757 or EU MRV Regulation) requiring vessels exceeding 5,000 gross tons using European Union ports to monitor, report and verify their carbon dioxide emissions beginning in January 2018, with the first reports due in 2019. In February 2019, the European Commission adopted a proposal to amend the EU MRV Regulation to harmonize the requirements of the EU MRV Regulation and the IMO DCS. Although, at present, the EU MRV Regulation is for monitoring, reporting and verification only, but it is anticipated that in the future the EU may move from requiring reporting of emissions to regulations aimed at reducing them.

        Any passage of climate control legislation or other regulatory initiatives by the IMO, the United States, the EU, Norway, Brazil or other countries where we operate, that restrict emissions of greenhouse gases could have a significant financial and operational impact on our business, including requiring us to make significant financial expenditures that we cannot predict with certainty at this time. For example, the Paris Agreement could lead to increased regulation of greenhouse gases or other concerns relating to climate change. In addition, even without such regulation, our business may be indirectly affected to the extent that climate change results in sea level changes or more intense weather events.

        Since the terrorist attacks of September 11, 2001, there have been a variety of initiatives intended to enhance vessel security. On November 25, 2002, the Maritime Transportation Security Act of 2002 (the "MTSA"), came into effect in the United States. To implement certain portions of the MTSA, in July 2003, the U.S. Coast Guard issued regulations requiring the implementation of certain security requirements aboard vessels operating in waters subject to the jurisdiction of the United States. Similarly, in December 2002, amendments to SOLAS created a new chapter of the convention dealing specifically with maritime security. The new chapter came into effect in July 2004 and imposes various detailed security obligations on vessels and port authorities, most of which are contained in the ISPS. The ISPS is designed to protect ports and international shipping against terrorism. After July 1, 2004, to trade internationally, a vessel must maintain an International Ship Security Certificate ("ISSC") from a recognized security organization approved by the vessel's flag state.

        Among the various requirements are:

56


Table of Contents

        The U.S. Coast Guard regulations, intended to align with international maritime security standards, exempt non-U.S. vessels from the MTSA vessel security measures provided such vessels have onboard a valid ISSC that attests to the vessel's compliance with SOLAS security requirements and the ISPS. KNOT has implemented the various security measures addressed by the MTSA, SOLAS and the ISPS.

Legal Proceedings

        From time to time we have been, and expect to continue to be, subject to legal proceedings and claims in the ordinary course of our business, principally personal injury and property casualty claims. These claims, even if lacking merit, could result in the expenditure of significant financial and managerial resources. We are not aware of any legal proceedings or claims that we believe will have, individually or in the aggregate, a material adverse effect on us.

Taxation of the Partnership

        Certain of our subsidiaries are subject to taxation in the jurisdictions in which they are organized, conduct business or own assets. We intend that our business and the business of our subsidiaries will be conducted and operated in a manner designed to minimize the tax imposed on us and our subsidiaries. However, we cannot assure this result as tax laws in these or other jurisdictions may change or we may enter into new business transactions relating to such jurisdictions, which could affect our tax liability.

        Because we and our subsidiaries do not conduct business or operations in the Republic of the Marshall Islands, neither we nor our subsidiaries are subject to income, capital gains, profits or other taxation under current Marshall Islands law, other than taxes, fines or fees due to (i) the incorporation, dissolution, continued existence, merger, domestication (or similar concepts) of legal entities registered in the Republic of the Marshall Islands, (ii) filing certificates (such as certificates of incumbency, merger, or redomiciliation) with the Marshall Islands registrar, (iii) obtaining certificates of good standing from, or certified copies of documents filed with, the Marshall Islands registrar, (iv) compliance with Marshall Islands law concerning vessel ownership, such as tonnage tax, or (v) non-compliance with requests made by the Marshall Islands Registrar of Corporations relating to our books and records and the books and records of our subsidiaries. As a result, distributions KNOT UK receives from its subsidiary, distributions that such subsidiary receives from the operating subsidiaries, and distributions we receive from KNOT UK, are not expected to be subject to Marshall Islands taxation.

        We have elected to be treated as a corporation for U.S. federal income tax purposes. As a result, we are subject to U.S. federal income tax to the extent we earn income from U.S. sources or income that is treated as effectively connected with the conduct of a trade or business in the United States unless such income is exempt from tax under an applicable treaty or Section 883 of the Code. Because

57


Table of Contents

our fleet is owned by subsidiaries resident in Norway, we expect that we qualify for an exemption from U.S. federal income tax on any U.S. source gross transportation income we earn by virtue of the application of the U.S.-Norway Tax Treaty, and we intend to take this position for U.S. federal income tax purposes.

        We are treated as fiscally transparent for Norwegian tax purposes and expect to organize our affairs and conduct our business in a manner such that we, and our remaining subsidiaries that are not organized under the laws of the Kingdom of Norway, are not subject to a material amount of Norwegian taxes.

        Our vessel-owning subsidiaries have been organized under the laws of the Kingdom of Norway, and we have elected to be subject to the tonnage tax regime in Norway. Pursuant to this regime, our vessel-owning subsidiaries will be subject to Norwegian tax based upon the net tonnage of their available cargo space rather than income generated from operating the vessels (i.e., operating income), which is tax free. Based upon the cargo space of our current vessels and the applicable rate of taxation, we expect our Norwegian subsidiaries to be liable for approximately $250,000 of Norwegian tonnage tax for the year ended December 31, 2018. In addition, under the tonnage tax regime, other income such as net financial income and expense (i.e. income not generated from operating the vessels) is subject to the regular corporate income tax rate.

        On December 14, 2017, the Norwegian government concluded negotiations with the EFTA Surveillance Authority regarding the Norwegian tonnage tax regime, which has been approved for another ten years until 2027. Pursuant to the approval, Norway has introduced restrictions that eliminate the ability of companies that own vessels under certain bareboat charters to qualify for the Norwegian tonnage tax regime. Companies that no longer qualify for the Norwegian tonnage tax regime will instead be subject to Norwegian corporate income tax. However, there are no limitations on intra-group bareboat chartering, as well as bareboat charters where crewing services are carried out by a related party. In order to constitute a related party, a minimum of 25% ownership/control is required according to the Norwegian General Taxation Act Section 8-13, paragraph 6. Due to the fact that KNOT owns more than 25% of our partnership interests and owns 100% of KNOT Management and KNOT Management Denmark (which provide these crewing services to us), our bareboat charters are effectively seen as time charter services to the customer. If this related party situation is ended, other alternatives and possibly mitigating measures would need to be evaluated by the Partnership. If there is a Brexit some of the existing UK flagged vessels will be reflagged to EU/EEA flag in order to meet any future national flag requirements.

        In case of a UK Brexit, dividend payments from KNOT Shuttle Tankers AS to KNOT UK will not be subject to withholding tax in Norway since KNOT UK owns more than 10% of the capital in KNOT Shuttle Tankers AS, c.f. the double tax treaty between Norway and the UK, article 10, paragraph 2.

        Although we are managed and controlled in the United Kingdom, we have obtained confirmation from HM Revenue & Customs that we are treated as a transparent partnership for United Kingdom tax purposes. Accordingly, we are not subject to UK tax in our own name, but rather any partners subject to UK tax will be taxed on their share of our profits.

        Our general partner and KNOT UK expect to be a resident of the United Kingdom for taxation purposes subject to tax on ordinary income. Nonetheless, these companies are primarily expected to earn dividend income from our controlled affiliates, which should generally be exempt from United Kingdom taxation under applicable exemptions for distributions from subsidiaries.

Employees

        We directly employ one onshore employee and no seagoing employees. As of December 31, 2018, KNOT employed (directly and through ship managers) approximately 502 seagoing staff to serve on our vessels. KNOT and its affiliates may employ additional seagoing staff to assist us as we grow. KNOT, through certain of its subsidiaries, provides onshore advisory, commercial, technical and operational support to our operating subsidiaries pursuant to the technical management agreements and management and administration agreements. Please read "Item 7. Major Unitholders and Related Party Transactions—Related Party Transactions."

        We and KNOT regard attracting and retaining motivated seagoing personnel as a top priority. KNOT offers seafarers competitive employment packages and opportunities for personal and career development, which relates to a philosophy of promoting internally. The officers operating our vessels are engaged on individual employment contracts, and we have entered into collective bargaining agreements that cover substantially all of the sailing personnel that operate the vessels in our current fleet, which are flagged in Norway, the Isle of Man, Malta, Denmark, United Kingdom or the Bahamas. We believe our relationships with these labor unions are good. Our commitment to training is fundamental to the development of the highest caliber of seafarers for our marine operations. KNOT's cadet training approach is designed to balance academic learning with hands-on training at sea. KNOT trains personnel mainly in Norway and the Philippines and at institutions that utilize ship handling, dynamic positioning and cargo handling simulators. After receiving formal instruction at one of these institutions, our seafarers' training continues onboard one of KNOT's vessels. Additional vessel and equipment training and courses are arranged in accordance with our training policies and the training requirements of our charterers. We believe that high-quality crewing and training policies will play an increasingly important role in distinguishing the larger, independent shipping companies with shuttle tanker experience from those that are newcomers and lack experienced, in-house staff and established expertise on which to base their customer service and safety operations.

        We are a publicly traded limited partnership formed on February 21, 2013.

Overview

        We were formed in February 2013 as a limited partnership under the laws of the Republic of the Marshall Islands to own and operate shuttle tankers under long-term charters. Our initial fleet of shuttle tankers was contributed to us by KNOT, a leading independent owner and operator of shuttle

tankers. Our current fleet consists of sixteen shuttle tankers. Under the Omnibus Agreement, we have the right to purchase from KNOT any shuttle tankers operating under charters of five or more years.

        On April 18, 2013, we completed our IPO. In connection with our IPO, we sold 8,567,500 common units to the public, through the underwriters, at a price of $21.00 per unit, and issued to KNOT 8,567,500 subordinated units and all of our incentive distribution rights. On May 18, 2016, all of the subordinated units converted into common units on a one for one basis. As of April 10, 2019, KNOT owned 26.2% of our common units, our general partner and our incentive distribution rights and our general partner owned a 1.85% general partner interest in us and 0.3% of our common units.

Significant Developments in 2018

        On January 30, 2018, the Partnership's subsidiary, Knutsen Shuttle Tankers 15 AS, which owns the vessel Torill Knutsen, closed a new $100 million senior secured term loan facility with a consortium of banks, in which The Bank of Tokyo-Mitsubishi UFJ acted as agent (the "Torill Facility"). The Torill Facility refinanced a $117 million loan facility associated with the Torill Knutsen that bore interest at a rate of LIBOR plus a margin of 2.5% and was due to be paid in full in November 2018. The Torill Facility is repayable in twenty-four (24) consecutive quarterly installments with a balloon payment of $60.0 million due at maturity. The Torill Facility bears interest at a rate per annum equal to LIBOR plus a margin of 2.1%. The facility matures in January 2024.

        On March 1, 2018, KNOT Shuttle Tankers AS acquired KNOT Shuttle Tankers 30 AS ("KNOT 30"), the company that owns the shuttle tanker Anna Knutsen from KNOT, for a purchase price of $120.0 million, less approximately $106.8 million of outstanding indebtedness related to the Anna Knutsen plus approximately $1.4 million for certain capitalized fees related to the financing of the Anna Knutsen and plus other purchase price adjustments of $5.3 million. On the closing of the acquisition, KNOT 30 repaid approximately $32.3 million of the indebtedness, leaving an aggregate of approximately $74.4 million of debt outstanding under the secured credit facility related to the vessel. The purchase price was settled in cash.

        On July 13, 2018, Shell exercised its option to extend the time charter of the Windsor Knutsen by one additional year until October 2019. Following the exercise of the option, Shell has four one-year options to extend the time charter.

        On December 17, 2018, the Partnership's subsidiary that owns the Windsor Knutsen and Shell agreed to suspend the vessel's time charter contract for a minimum of 10 months and a maximum of 12 months. The suspension period commenced March 4, 2019. During the suspension period, the Windsor Knutsen will operate under a time charter contract with Knutsen Shuttle Tankers Pool AS, a wholly owned subsidiary of KNOT, on the same terms as the existing time charter contract with Shell. The Partnership agreed to the suspension of the contract with Shell and the substitute time charter in order to accommodate the mutual needs of Shell and Knutsen Shuttle Tankers Pool AS.

        On August 3, 2018, the Partnership entered into an amended time charter with Eni, extending the duration of the Hilda Knutsen time charter for four years until August 2022, with options to extend until 2025.

        On September 5, 2018, Eni, exercised its option to extend the time charter of the Torill Knutsen by one additional year until November 2019. Following the exercise of the option, Eni has four one-year options to extend the time charter.

        On September 20, 2018 the Partnership's subsidiaries which own the Windsor Knutsen, the Bodil Knutsen, the Fortaleza Knutsen, the Recife Knutsen, the Carmen Knutsen and the Ingrid Knutsen (the "Vessels"), refinanced their existing bank debt, entering new long-term senior secured credit facilities (the "Multi-vessels Facility"). The new senior secured credit facilities consist of a term loan of $320 million and a $55 million revolving credit facility.

        The term loan is repayable in 20 consecutive quarterly installments, with a balloon payment of $177 million due at maturity in September 2023. The term loan bears interest at a rate per annum equal to LIBOR plus a margin of 2.125%. The revolving credit facility will mature in September 2023, and bears interest at LIBOR plus a margin of 2.125%. There is a commitment fee of 0.85% payable on the undrawn portion of the revolving credit facility. The loans are guaranteed by the Partnership and secured by mortgages on the Vessels. The Multi-vessels Facility refinanced previously existing term loans and a revolving credit facility previously secured by the Vessels.

        On November 9, 2018, Equinor ASA exercised its option to extend the time charter of the Bodil Knutsen by one additional year until May 2020. Following the exercise of the option, Equinor has four one-year options to extend the time charter.

Market Overview and Trends

        As of April 2019, the shuttle tanker market consisted of approximately 88 vessels (including 15 newbuilds on order) characterized by long-term charters with offshore oil producers. Most shuttle tankers operate in the North Sea or offshore Brazil. Demand for shuttle tankers is based on offshore oilfield development and prior to mid-2014, higher oil prices and a positive long-term offshore oil outlook led to increased activity. In the past four years, oil companies delayed oil production start-ups in both the North Sea and Brazil. Project startups are increasing, and the existing fleet is aging. Due to the age structure of the fleet and the relatively high number of projects under development, we believe the medium to long-term outlook continues to be positive and tendering activity for new projects is expected in 2019. For 2018, two new shuttle tankers were ordered to operate in the North Sea. In addition, there were 7 new shuttle tanker contracts awarded for Brazilian operations during 2018

        Oil prices declined significantly in the latter part of 2014 and in 2015 due to an increase in US shale oil production, coupled with increased production from certain OPEC states. Oil prices recovered to a certain degree in 2016 and this continued throughout 2017 and 2018. Existing offshore oil production projects under development where shuttle tankers are required, are unaffected by the volatility in oil prices. Longer term reductions in oil prices could impact the rate of growth of offshore oil production activity when existing projects and projects under development are completed.

Factors Affecting Our Results of Operations

        We believe the principal factors that will affect our future results of operations include:

        Please read "Item 3. Key Information—Risk Factors" for a discussion of certain risks inherent in our business.

Important Financial and Operational Terms and Concepts

        We use a variety of financial and operational terms and concepts when analyzing our performance. These include the following:

        Time Charter and Bareboat Revenues.    Revenues from time charters and bareboat charters are recognized as operating leases on a straight-line basis over the term of the charter, net of any commissions. Under time charters, revenue is not recognized during days a vessel is off-hire. Revenue is recognized from delivery of the vessel to the charterer until the end of the lease term. Under time charters, we are responsible for providing the crewing and other services related to the vessel's operation, the cost of which is included in the daily hire rate, except when off-hire. Under bareboat charters, we provide a specified vessel for a fixed period of time at a specified hire rate. Revenues are

67


Table of Contents

affected by hire rates and the number of days a vessel operates as well as the mix of business between time charters and bareboat charters.

        Voyage Expenses.    Voyage expenses are all expenses unique to a particular voyage, including any bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls and agency fees. Voyage expenses are typically paid by the customer under time charters and bareboat charters. Voyage expenses are paid by the shipowner during spot contracts and periods of off-hire and are recognized when incurred.

        Vessel Operating Expenses.    Vessel operating expenses include crewing, repairs and maintenance, insurance, stores, lube oil and communication expenses. Vessel operating expenses are generally paid by the shipowner under time charters and spot contracts and are recognized when incurred. Vessel operating expenses are paid by the customer under bareboat charters.

        Off-hire.    Under our time charters, when the vessel is off-hire, or not available for service, the customer generally is not required to pay the hire rate, and the shipowner is responsible for all costs. Prolonged off-hire may lead to a termination of the time charter. A vessel generally will be deemed off-hire if there is a loss of time due to, among other things, operational deficiencies, drydocking for repairs, maintenance or inspection, equipment breakdowns, delays due to accidents, crewing strikes, certain vessel detentions or similar problems or the shipowner's failure to maintain the vessel in compliance with its specifications and contractual standards or to provide the required crew. Our bareboat charters do not contain provisions for off-hire. We have obtained loss of hire insurance to protect us against loss of income in the event one of our vessels cannot be employed due to damage that is covered under the terms of our hull and machinery insurance. Under our loss of hire policies, our insurer generally will pay us the hire rate agreed in respect of each vessel for each day in excess of 14 days and with a maximum period of 180 days.

        Drydocking.    We must periodically drydock each of our vessels for inspection, repairs and maintenance and any modifications required to comply with industry certification or governmental requirements. In accordance with industry certification requirements, we drydock our vessels at least every 60 months until the vessel is 15 years old, after which drydocking takes place at least every 30 months thereafter as required for the renewal of certifications required by classification societies. For vessels operating on time charters, we capitalize the costs directly associated with the classification and regulatory requirements for inspection of the vessels and improvements incurred during drydocking that increase the earnings capacity or improve the efficiency or safety of the vessels. We expense costs related to routine repairs and maintenance performed during drydocking or as otherwise incurred. For vessels operating on bareboat charters, the customer bears the cost of any drydocking. The number of drydockings undertaken in a given period and the nature of the work performed determine the level of drydocking expenditures.

        Depreciation.    Depreciation on vessels and equipment is calculated on a straight-line basis over the asset's estimated useful life of 25 years for the hull and equipment, less an estimated residual value. Drydocking cost is depreciated on a straight-line basis over the period until the next planned drydocking takes place. For vessels that are newly built or acquired, an element of the cost of the vessel is allocated initially to a drydock component and depreciated on a straight-line basis over the period until the next planned drydocking. When significant drydocking expenditures occur prior to the expiration of this period, we expense the remaining balance of the original drydocking cost in the month of the subsequent drydocking.

        Impairment of Long-Lived Assets.    Vessels and equipment, vessels under construction and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, we first compare the

68


Table of Contents

undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

        Other Finance Expense.    Other finance expense includes external bank fees, financing service fees paid to related parties and guarantee commissions paid to external and related parties in connection with our debt and other bank services.

        Revenue Days.    Revenue days are the total number of calendar days our vessels were in our possession during a period, less the total number of off-hire days during the period associated with major repairs, or drydockings. Consequently, revenue days represent the total number of days available for the vessel to earn revenue. Idle days, which are days when the vessel is available to earn revenue, yet is not employed, are included in revenue days. We use revenue days to highlight changes in net voyage revenues between periods.

        Average Number of Vessels.    The historical average number of vessels consists of the average number of owned vessels that are in our possession during the periods presented. We use average number of vessels primarily to highlight changes in vessel operating expenses, hire rate expense and depreciation and amortization.

Insurance

        Hull and Machinery Insurance.    We have obtained hull and machinery insurance on all our vessels to insure against marine and war risks, which include the risks of damage to our vessels, salvage and towing costs, and also insures against actual or constructive total loss of any of our vessels. However, our insurance policies contain deductible amounts for which we are responsible. We have also arranged additional total loss coverage for each vessel. This coverage, which is called hull interest and freight interest coverage, provides us additional coverage in the event of the total loss or the constructive total loss of a vessel.

        Loss of Hire Insurance.    We have obtained loss of hire insurance to protect us against loss of income in the event one of our vessels cannot be employed due to damage that is covered under the terms of our hull and machinery insurance. Under our loss of hire policies, our insurer will pay us the hire rate agreed in respect of each vessel for each day, in excess of a certain number of deductible days, for the time that the vessel is out of service as a result of damage, for a maximum of 180 days. The number of deductible days for the vessels in our fleet is 14 days per vessel.

        All of our hull and machinery, hull interest and freight interest and loss of hire insurance policies are written on the NMIP, which through the hull and maintenance coverage also offers comprehensive collision liability coverage of up to the insured hull and maintenance value of the vessel. NMIP is based on an "all risk principle" and offers what is considered to be the most comprehensive insurance obtainable in any of the world's marine markets today. The agreed deductible on each vessel averages $150,000.

        Protection and Indemnity Insurance.    Protection and indemnity insurance, which covers our third-party legal liabilities in connection with our shipping activities, is provided by a P&I club. This includes third-party liability and other expenses related to the injury or death of crew members, passengers and other third-party persons, loss or damage to cargo, claims arising from collisions with other vessels or from contact with jetties or wharves and other damage to other third-party property, including pollution arising from oil or other substances, and other related costs, including wreck removal. Our current protection and indemnity insurance coverage is unlimited, except for pollution, which is limited to $1 billion per vessel per incident.

        Time Charter and Bareboat Revenues.    Time charter and bareboat revenues for the year ended December 31, 2018 were $278.2 million, an increase of $65.7 million compared to $212.5 million for the year ended December 31, 2017. This increase was mainly due to increased revenues of $57.9 million resulting from the Anna Knutsen, the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen and the Tordis Knutsen being included in our results of operations from March 1, 2018, December 15, 2017, September 30, 2017, June 1, 2017 and March 1, 2017, respectively, and full earnings from the Windsor Knutsen and the Carmen Knutsen due to planned drydocking in 2017. The increase was partially offset by a $2.8 million decrease in time charter revenues due to drydocking of the Hilda Knutsen, the Torill Knutsen and the Ingrid Knutsen in 2018 and by a $0.4 million decrease due to an accrual for estimated underperformance of the Hilda Knutsen and the Torill Knutsen in 2017.

        Loss of hire insurance recoveries.    Loss of hire insurance recoveries for the year ended December 31,2018 were $0.5 million compared to $5.2 million for the year ended December 31,2017. The loss of hire insurance recoveries were related to a technical default with the Raquel Knutsen's controllable pitch propeller and a default with the Carmen Knutsen's propeller shaft.

        Other Income.    Other income for the year ended December 31, 2018 was $0.8 million, a decrease of $0.7 million compared to $1.5 million for the year ended December 31, 2017. In October 2015, the Windsor Knutsen commenced operating under a new time charter. The hire rate for the new charter is below the initial charter hire rate and the difference between the new hire rate and the initial rate was paid by KNOT until April 2018. During the year ended December 31, 2018, $0.8 million was recognized as other income pursuant to this guarantee for the Windsor Knutsen compared with $1.2 million in 2017. In addition, $0.3 million was recognized as other income in 2017 connected to the reimbursement for repairs and lost hire from KNOT for the Vigdis Knutsen due to a hull damage incident in June 2017.

        Vessel Operating Expenses.    Vessel operating expenses for the year ended December 31, 2018 were $56.7 million, an increase of $10.0 million from $46.7 million in the year ended December 31, 2017. The increase was primarily due to (i) an increase of $15.0 million from the Anna Knutsen, the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen and the Tordis Knutsen being included in the results of operations from March 1, 2018, December 15, 2017, September 30, 2017, June 1, 2017 and March 1, 2017, respectively and (ii) an increase of $0.8 million related to bunkers consumption in connection with the drydocking of the Brasil Knutsen in the end of the first quarter of 2018. The increase was partially offset by $0.6 million related to bunkers consumption in connection with the drydocking of the Windsor Knutsen in 2017 and by $5.2 million related to the insurance claim and drydocking of the Carmen Knutsen.

        Depreciation.    Depreciation for the year ended December 31, 2018 was $88.8 million, an increase of $17.2 million from $71.6 million in the year ended December 31, 2017. This increase was mainly due to the Anna Knutsen, the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen and the Tordis Knutsen being included in results of operations from March 1, 2018, December 15, 2017, September 30, 2017, June 1, 2017 and March 1, 2017, respectively.

        General and Administrative Expenses.    General and administrative expenses for the year ended December 31, 2018 were $5.3 million, compared to $5.6 million for 2017. The decrease is mainly due to lower activity due to incremental expenses incurred in connection with the common and preferred unit offerings in 2017. The decrease was partly offset by increased costs due to the acquisitions of the Anna Knutsen, the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen and the Tordis Knutsen.

        Interest Income.    Interest income for the year ended December 31, 2018 was $739,000 compared to $248,000 for 2017.

        Interest Expense.    Interest expense for the year ended December 31, 2018 was $50.0 million, an increase of $19.2 million from $30.7 million for the year ended December 31, 2017. The increase was mainly due to additional debt incurred in connection with the acquisitions of the Anna Knutsen, the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen and the Tordis Knutsen, the refinancing of the Hilda Knutsen and the Torill Knutsen and higher LIBOR during the year ended December 31, 2018 compared to the year ended December 31, 2017.

        Other Finance Expense.    Other finance expense for the year ended December 31, 2018 was $1.3 million, a decrease of $0.1 million from $1.4 million for the year ended December 31, 2017. Other finance expenses are primarily related to bank fees and guarantee commissions.

        Time Charter and Bareboat Revenues.    Time charter and bareboat revenues for the year ended December 31, 2017 were $212.5 million, an increase of $39.6 million compared to $172.9 million for the year ended December 31, 2016. This increase was mainly due to increased revenues of $48.9 million resulting from the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen, the Tordis Knutsen and the Raquel Knutsen being included in our results of operations from December 15, 2017, September 30, 2017, June 1, 2017, March 1, 2017 and December 1, 2016, respectively, and full earnings from the Bodil Knutsen due to planned drydocking in 2016. The increase was partially offset by a $8.7 million decrease in time charter revenues due to drydocking and repairs of the Carmen Knutsen and drydocking of the Windsor Knutsen in 2017 and by a $0.4 million decrease due to an accrual for estimated underperformance of the Hilda Knutsen and the Torill Knutsen in 2017.

        Loss of hire insurance recoveries.    Loss of hire insurance recoveries for the year ended December 31,2017 were $5.2 million compared to $nil million for the year ended December 31,2016. The loss of hire insurance recoveries were related to a technical default with the Raquel Knutsen's controllable pitch propeller and a default with the Carmen Knutsen's propeller shaft.

        Other Income.    Other income for the year ended December 31, 2017 was $1.5 million, an increase of $0.7 million compared to $0.8 million for the year ended December 31, 2016. Pursuant to the Omnibus Agreement, KNOT agreed to guarantee the payment of the hire rate that is equal to or greater than the hire rate payable under the initial charters of the Bodil Knutsen and Windsor Knutsen for a period of five years from the closing date of the IPO. In October 2015, the Windsor Knutsen commenced operating under a new time charter. The hire rate for the new charter is below the initial charter hire rate and the difference between the new hire rate and the initial rate was paid by KNOT. During the year ended December 31, 2017, $1.2 million was recognized as other income pursuant to this guarantee for the Windsor Knutsen compared with $0.8 million in 2016. In addition, $0.3 million connected to the reimbursement for repairs and lost hire from KNOT for the Vigdis Knutsen due to a hull damage incident in June 2017 was recognized as other income.

        Vessel Operating Expenses.    Vessel operating expenses for the year ended December 31, 2017 were $46.7 million, an increase of $15.8 million from $30.9 million in the year ended December 31, 2016. The increase was primarily due to an increase of $11.5 million due to the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen, the Tordis Knutsen and the Raquel Knutsen being included in the results of operations from December 15, 2017, September 30, 2017, June 1, 2017, March 1, 2017 and

Table of Contents

December 1, 2016, respectively. $2.9 million of the increase is due to incidents and insurance claims relating to the Raquel Knutsen, the Tordis Knutsen, the Vigdis Knutsen and the Carmen Knutsen and $1.4 million of the increase is due to bunkers consumption in connection with the drydocking of the Carmen Knutsen and the Windsor Knutsen.

        Depreciation.    Depreciation for the year ended December 31, 2017 was $71.6 million, an increase of $15.4 million from $56.2 million in the year ended December 31, 2016. This increase was mainly due to the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen, the Tordis Knutsen and the Raquel Knutsen being included in results of operations from December 15, 2017, September 30, 2017, June 1, 2017, March 1, 2017 and December 1, 2016, respectively.

        General and Administrative Expenses.    General and administrative expenses for the year ended December 31, 2017 were $5.6 million, compared to $4.4 million for 2016. The increase is mainly due to incremental expenses incurred in connection with the common unit offerings, private placements of Series A Preferred Units and the acquisitions of the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen, the Tordis Knutsen and the Raquel Knutsen.

        Interest Income.    Interest income for the year ended December 31, 2017 was $248,000 compared to $24,000 for 2016.

        Interest Expense.    Interest expense for the year ended December 31, 2017 was $30.7 million, an increase of $9.8 million from $20.9 million for the year ended December 31, 2016. The increase was mainly due to additional debt incurred in connection with the acquisitions of the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen, the Tordis Knutsen and the Raquel Knutsen, the refinancing of the Hilda Knutsen and the drawdowns of the revolving credit facilities and higher LIBOR during the year ended December 31, 2017 compared to the year ended December 31, 2016.

        Other Finance Expense.    Other finance expense for the year ended December 31, 2017 was $1.4 million, an increase of $0.1 million from $1.3 million for the year ended December 31, 2016. Other finance expenses are primarily related to bank fees and guarantee commissions.

B.    Liquidity and Capital Resources

Liquidity and Cash Needs

        We operate in a capital-intensive industry, and we expect to finance the purchase of additional vessels and other capital expenditures through a combination of borrowings from commercial banks, cash generated from operations and debt and equity financings. In addition to paying distributions, our other liquidity requirements relate to servicing our debt, funding investments (including the equity portion of investments in vessels), funding working capital and maintaining cash reserves against fluctuations in operating cash flows. We believe our current resources are sufficient to meet our working capital requirements for our current business. Generally, our long-term sources of funds are cash from operations, long-term bank borrowings and other debt and equity financings. Because we distribute our available cash, we expect to rely upon external financing sources, including bank borrowings and the issuance of debt and equity securities, to fund acquisitions and other expansion capital expenditures.

        Our funding and treasury activities are intended to maximize investment returns while maintaining appropriate liquidity. Cash and cash equivalents are held primarily in U.S. Dollars with some balances held in NOK, British Pounds and Euros. We have not made use of derivative instruments other than for interest rate and currency risk management purposes, and we expect to continue to economically hedge our exposure to interest rate fluctuations in the future by entering into new interest rate swap contracts.

        We estimate that we will spend in total approximately $42.6 million for drydocking and classification surveys for the twelve vessels under time charters in our fleet as of March 31, 2019 between 2019 and 2023. As our fleet matures and expands, our drydocking expenses will likely increase. Ongoing costs for compliance with environmental regulations are primarily included as part of our drydocking and society classification survey costs or are a component of our vessel operating expenses. We are not aware of any regulatory changes or environmental liabilities that we anticipate will have a material impact on our current or future operations. There will be further costs related to voyages to and from the drydocking yard that will depend on the distance from the vessel's ordinary trading area to the drydocking yard.

        On January 30, 2018, the Partnership's subsidiary, Knutsen Shuttle Tankers 15 AS, which owns the vessel Torill Knutsen, closed a new $100 million senior secured term loan facility with a consortium of banks, in which The Bank of Tokyo-Mitsubishi UFJ acted as agent. The Torill Facility refinanced a $117 million loan facility associated with the Torill Knutsen that bore interest at a rate of LIBOR plus a margin of 2.5% and was due to be paid in full in November 2018.

        On March 1, 2018, KNOT Shuttle Tankers AS acquired KNOT 30, the company that owns the shuttle tanker Anna Knutsen from KNOT, for a purchase price of $120.0 million, less approximately $106.8 million of outstanding indebtedness related to the Anna Knutsen plus approximately $1.4 million for certain capitalized fees related to the financing of the Anna Knutsen and plus other purchase price adjustments of $5.3 million. On the closing of the acquisition, KNOT 30 repaid approximately $32.3 million of the indebtedness, leaving an aggregate of approximately $74.4 million of debt outstanding under the secured credit facility related to the vessel. The purchase price was settled in cash.

        On September 20, 2018, the Partnership's subsidiaries which own the Windsor Knutsen, the Bodil Knutsen, the Fortaleza Knutsen, the Recife Knutsen, the Carmen Knutsen and the Ingrid Knutsen refinanced their existing bank debt, entering new long-term senior secured credit facilities, the Multi-vessels Facility. The Multi-vessels Facility consists of a term loan of $320 million and a $55 million revolving credit facility.

        As of December 31, 2018, the Partnership had available liquidity of $70.4 million, which consisted of cash and cash equivalents of $41.7 million and availability under the revolving credit facilities of $28.7 million. As of April 10, 2019, the revolving credit facilities had an aggregate undrawn capacity of $28.7 million.

        The consolidated financial statements have been prepared assuming that the Partnership will continue as a going concern. As of December 31, 2018, the Partnership's net current liabilities were $76.0 million. Included in current liabilities are short term loan obligations that mature before December 31, 2019 and are therefore, presented as current debt.

        The Partnership expects that its primary future sources of funds will be available cash, cash from operations, borrowings under any new loan agreements and the proceeds of any equity financings. The Partnership believes that these sources of funds (assuming the current rates earned from existing charters) will be sufficient to cover operational cash outflows and ongoing obligations under the Partnership's financing commitments to pay loan interest and make scheduled loan repayments and to make distributions on its outstanding units. Accordingly, the Partnership believes that its current resources, including amounts available to be drawn under the revolving credit facilities of $28.7 million, are sufficient to meet working capital requirements for its current business for at least the next twelve months.

Capital Expenditures

        We reserve cash from operations for future maintenance capital expenditures, working capital and other matters. Because of the substantial capital expenditures we are required to make to maintain our fleet, our annual estimated maintenance and replacement capital expenditures are $55.5 million, which is comprised of $47.0 million for replacing our current vessels at the end of their useful lives and $8.5 million for drydocking maintenance and classification surveys.

Net Cash Provided by Operating Activities

        Net cash provided by operating activities decreased by $5.9 million to $148.6 million for the year ended December 31, 2018 compared to $154.6 million for 2017. The decrease was mainly due to changes in working capital elements, especially in amounts due to and from related parties, and increase drydocking expenditures of $12.4 million for the scheduled drydocking of the Brasil Knutsen, the Hilda Knutsen, the Torill Knutsen and the Ingrid Knutsen in 2018 compared to drydocking expenditures of $6.9 million for the scheduled drydocking of the Windsor Knutsen and Carmen Knutsen in 2017. The decrease was partially offset by higher earnings from the Anna Knutsen, the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen and the Tordis Knutsen being included in our results of operations as of March 1, 2018, December 15, 2017, September 30, 2017, June 1, 2017 and March 1, 2017, respectively.

        Net cash provided by operating activities increased by $46.1 million to $154.6 million for the year ended December 31, 2017 compared to $108.5 million for 2016. The increase was mainly due to higher earnings through the contributions from the Brasil Knutsen, the Lena Knutsen, the Vigdis Knutsen, the Tordis Knutsen and the Raquel Knutsen being included in our results of operations as of December 15, 2017, September 30, 2017, June 1, 2017, March 1, 2017 and December 1, 2016, respectively. The increase was partially offset by increased drydocking expenditures of $6.9 million for the scheduled drydocking of the Windsor Knutsen and Carmen Knutsen in 2017 compared to drydocking expenditures of $2.5 million for the scheduled drydocking of the Bodil Knutsen in 2016.

Net Cash Used in Investing Activities

        Net cash used in investing activities was $15.5 million for the year ended December 31, 2018 compared to $94.9 million for the year ended December 31, 2017. Net cash used in investing activities in 2018 of $15.5 million was mainly due to the acquisition of the Anna Knutsen for which we paid a net cash amount to cover the difference between the purchase consideration of $120.0 million less $106.8 million of outstanding indebtedness plus approximately $1.4 million for certain capitalized fees related to the financing of the vessel and plus other purchase price adjustments of $5.3 million. Net cash used in investing activities is net of cash acquired from the acquisition of the Anna Knutsen of $4.5 million.

        Net cash used in investing activities was $94.9 million for the year ended December 31, 2017 compared to $14.0 million for the year ended December 31, 2016. Net cash used in investing activities in 2017 of $94.4 million related to the following acquisitions:

        The Anna Facility also identifies various events that may trigger mandatory reduction, prepayment and cancellation of the facility, including total loss or sale of a vessel and customary events of default. As of December 31, 2018, the borrower and the guarantors were in compliance with all covenants under this facility.

        In August 2017, KNOT Shuttle Tankers AS entered into an unsecured revolving credit facility of $25 million with NTT Finance Corporation. The facility will mature in August 2019, bears interest at LIBOR plus a margin of 1.8% and has a commitment fee of 0.5% on the undrawn portion of the facility.

        We use derivative instruments to reduce the risks associated with fluctuations in interest rates. We have a portfolio of interest rate swap contracts that exchange or swap floating rate interest to fixed rates, which, from a financial perspective, hedges our obligations to make payments based on floating interest rates. As of December 31, 2018, the Partnership's net exposure to floating interest rate fluctuations on its outstanding debt was approximately $490.1 million based on total interest-bearing debt outstanding of $1,087.3 million, less interest rate swaps of $555.5 million, less cash and cash equivalents of $41.7 million. Our interest rate swap contracts mature between July 2020 and August 2027. Under the terms of the interest rate swap agreements, we will receive from the counterparty interest on the notional amount based on three-month and six-month LIBOR and will pay to the counterparty a fixed rate. For the interest rate swap agreements above, we will pay to the counterparty a weighted average interest rate of 1.86%.

        We enter into foreign exchange forward contracts in order to manage our exposure to the risk of movements in foreign currency exchange rate fluctuations. As of December 31, 2018, the total contract amount in foreign currency of our outstanding foreign exchange forward contracts that were entered into to economically hedge our outstanding future payments in currencies other than the U.S. Dollar was NOK 244.2 million. We do not apply hedge accounting for derivative instruments.

Critical Accounting Estimates

        The preparation of the Partnership's consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures about contingent assets and liabilities. We base these estimates and assumptions on historical experience and on various other information and assumptions that we believe to be reasonable. Our critical accounting estimates are important to the portrayal of both our financial condition and results of operations and require us to make subjective or complex assumptions or estimates about matters that are uncertain. Significant accounting policies are discussed in Note 2—Summary of Significant Accounting Policies in the consolidated financial statements included in this Annual Report. We believe that the following are the critical accounting estimates used in the preparation of our Partnership's consolidated financial statements. In addition, there are other items within the Partnership's consolidated financial statements that require estimation.

88


Table of Contents

        Description.    The carrying value of vessels and equipment represent its historical acquisition or construction cost, including capitalized interest, supervision and technical and delivery cost, net of accumulated depreciation and impairment loss, if any. Expenditures for subsequent conversions and major improvements are capitalized, provided that such costs increase the earnings capacity or improve the efficiency or safety of the vessels. We depreciate the original cost, less an estimated residual value, of our vessels on a straight-line basis over each vessel's estimated useful life. Depreciation on our shuttle tankers is calculated using an estimated useful life of 25 years, commencing at the date the vessel was originally delivered from the shipyard. However, the actual life of a vessel may be different than the estimated useful life, with a shorter actual useful life resulting in an increase in the depreciation and potentially resulting in an impairment loss. The estimated useful life of our vessels takes into account design life, commercial considerations and regulatory restrictions. The carrying value of our vessels may not represent their market value at any point in time, because the market prices of second-hand vessels tend to fluctuate with changes in hire rates and the cost of newbuilds.

        We review vessels and equipment for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable, which occurs when the asset's carrying value is greater than the future undiscounted cash flows the asset is expected to generate over its remaining useful life. For a vessel under charter, the discounted cash flows from that vessel may exceed its market value, as market values may assume the vessel is not employed on an existing charter. If the estimated future undiscounted cash flows of an asset exceed the asset's carrying value, no impairment is recognized even though the fair value of the asset may be lower than its carrying value. If the estimated future undiscounted cash flows of an asset are less than the asset's carrying value and the fair value of the asset is less than its carrying value, the asset is written down to its fair value. Fair value may be determined through various valuation techniques but is generally calculated as the net present value of estimated future cash flows.

        Our business model is to employ our vessels on fixed-rate charters with major energy companies. These charters typically have original terms between five to ten years in length. Consequently, while the market value of a vessel may decline below its carrying value, the carrying value of a vessel may still be recoverable based on the future undiscounted cash flows the vessel is expected to obtain from servicing its existing and future charters.

        Judgments and Uncertainties.    Our estimates of future cash flows involve assumptions about future hire rates, vessel utilization, operating expenses, drydocking expenditures, vessel residual values and the remaining estimated life of our vessels. Our estimated hire rates are based on rates under existing vessel charters and market rates at which we expect we can re-charter our vessels. Our estimates of vessel utilization, including estimated off-hire time and the estimated amount of time our shuttle tankers may spend operating in the spot market when not being used in their capacity as shuttle tankers, are based on historical experience of KNOT and our projections of future shuttle tanker voyages. Our estimates of operating expenses and drydocking expenditures are based on historical operating and drydocking costs of KNOT and our expectations of future cost and operating requirements. Vessel residual values are a product of a vessel's lightweight tonnage and an estimated scrap rate. The remaining estimated lives of our vessels used in our estimates of future cash flows are consistent with those used in the calculation of depreciation. Certain assumptions relating to our estimates of future cash flows are more predictable by their nature in our experience, including estimated revenue under existing charter terms, ongoing operating costs and remaining vessel lives. Certain assumptions relating to our estimates of future cash flows require more discretion and are inherently less predictable, such as future hire rates beyond the firm period of existing charters and vessel residual values, due to factors such as the volatility in hire rates and vessel residual values. We believe that the assumptions used to estimate future cash flows of our vessels are reasonable at the

89


Table of Contents

time they are made. We can make no assurances, however, as to whether our estimates of future cash flows, particularly future hire rates or vessel residual values, will be accurate.

        Effect If Actual Results Differ from Assumptions.    If we conclude that a vessel or equipment is impaired, we recognize a loss in an amount equal to the excess of the carrying value of the asset over its fair value at the date of impairment. The fair value at the date of the impairment becomes the new cost basis and will result in a lower depreciation expense than for periods before the vessel or equipment impairment.

        In "—Vessel Lives and Impairment" above, we discuss our policy for assessing impairment of the carrying value of our vessels. During the past few years, the market values of certain vessels in the worldwide fleet have experienced particular volatility, with substantial declines in many vessel classes. There is a future risk that the sale value of certain of our vessels could decline below those vessels' carrying value, even though we would not impair those vessels' carrying value under our accounting impairment policy, due to our belief that future undiscounted cash flows expected to be earned by such vessels over their operating lives would exceed such vessels' carrying value.

        In connection with monitoring compliance with our credit facilities and as a general business matter, we periodically monitor the market value of our vessels, including obtaining various broker valuations as of specific dates. We generally do not include the impact of market fluctuations in vessel prices in our financial statements. We do, however, monitor our business and assets on a regular basis for potential asset impairment as described above. The total carrying value of our vessels was $1,767 million as of December 31, 2018. With respect to the vessels, based on broker valuations as of December 31, 2018 on a charter free basis, we believe the aggregate market value of these vessels was less than their aggregate carrying value as of that date. We believe the aggregate amount of this deficit as of December 31, 2018 for the vessels was approximately $144 million. These vessels do, however, have fixed rates charters contracts. We did not identify any impairment indicators for our vessels as of December 31, 2018, and accordingly, we have not performed an undiscounted cash flow test or recorded impairment charges.

        Description.    We drydock each of our vessels periodically for inspection, repairs and maintenance and for any modifications to comply with industry certification or governmental requirements. For vessels operating on time charters, we capitalize the costs directly associated with the classification and regulatory requirements for inspection of the vessels, major repairs and improvements incurred during drydocking that increase the earnings capacity or improve the efficiency or safety of the vessels. Drydocking cost is amortized on a straight-line basis over the period until the next planned drydocking. We expense costs related to routine repairs and maintenance performed during drydocking or as otherwise incurred. For vessels that are newly built or acquired, an element of the cost of the vessel is allocated initially to a drydock component and amortized on a straight-line basis over the period until the next planned drydocking. When significant drydocking expenditures occur prior to the expiration of this period, we expense the remaining unamortized balance of the original drydocking cost in the month of the subsequent drydocking. For vessels operating on bareboat charters, the charterer bears the cost of any drydocking.

        Judgments and Uncertainties.    Amortization of capitalized drydock expenditures requires us to estimate the period of the next drydocking or estimated useful life of drydock expenditures. While we typically drydock our vessels every 60 months until the vessel is 15 years old and every 30 months thereafter, we may drydock the vessels at an earlier date.

Table of Contents

        Effect if Actual Results Differ from Assumptions.    A change in our estimate of the useful life of a drydock will have a direct effect on our amortization of drydocking expenditures.

        Description.    We allocate the cost of acquired companies to the identifiable tangible and intangible assets and liabilities acquired, with the remaining amount being classified as goodwill. Certain intangible assets, such as above-market contracts, are being amortized over time. Our future operating performance will be affected by the amortization of intangible assets and potential impairment charges related to goodwill or intangible assets. Accordingly, the allocation of purchase price to intangible assets and goodwill may significantly affect our future operating results. Goodwill is not amortized, but reviewed for impairment annually, or more frequently if impairment indicators arise. The process of evaluating the potential impairment of goodwill is highly subjective and requires significant judgment at many points during the analysis. No goodwill or intangible assets arose as a result of acquisitions carried out for the years ended December 31, 2018, 2017 and 2016.

        Judgments and Uncertainties.    The allocation of the purchase price of acquired companies requires management to make significant estimates and assumptions, including estimates of future cash flows expected to be generated by the acquired assets and the appropriate discount rate to value these cash flows. In addition, the process of evaluating the potential impairment of goodwill and intangible assets is highly subjective and requires significant judgment at many points during the analysis. We test goodwill for impairment using a two-step analysis, with the option of performing a qualitative assessment before performing the first step of the two-step analysis, whereby the carrying value of the reporting unit is compared to its fair value in the first step. If the carrying value of the reporting unit is greater than its fair value, the second step is performed, where the implied fair value of goodwill is compared to its carrying value. An impairment charge is recognized for the amount by which the carrying amount of goodwill exceeds its fair value. The fair value is estimated using the net present value of discounted cash flows of the reporting unit. The estimates and assumptions regarding expected future cash flows and appropriate discount rates are in part based upon existing contracts, future shuttle tanker rates, historical experience, financial forecasts and industry trends and conditions.

        Description.    We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized.

        Judgments and Uncertainties.    We record a valuation allowance for deferred tax assets when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. The future realization of deferred tax assets depends on the existence of sufficient taxable income of the appropriate character in the carry forward period. This analysis requires, among other things, the use of estimates and projections in determining future reversals of temporary differences and forecasts of future profitability and evaluating potential tax-planning strategies. The valuation allowances as of December 31, 2018 were related to the financial loss carry forwards and other net deferred tax assets for Norwegian tonnage tax. In assessing the realizability of deferred tax assets, we considered all the positive and negative evidence available. Given our cumulative loss position for tonnage tax, we determined it was more likely than not that some of the benefit from the deferred tax assets would not be realized based on the weight of available evidence. As of December 31, 2018, we determined that the deferred tax assets are likely to not be realized, and the booked value was, therefore, zero.

        Effect If Actual Results Differ from Assumptions.    If we determined that we were able to realize a net deferred tax asset in the future, in excess of the net recorded amount, an adjustment to decrease the valuation allowance related to the deferred tax assets would typically increase our net income (or

91


Table of Contents

decrease our loss) in the period such determination was made. As of December 31, 2018 and 2017, we had a valuation allowance for deferred tax assets of $17.0 million and $15.7 million, respectively.

        In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606), as subsequently updated by the FASB, which provides new authoritative guidance on the methods of revenue recognition and related disclosure requirements. This new standard supersedes existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. This update creates a five-step model and requires a company to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligation in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue as each performance obligation is satisfied. Under the new standard, additional qualitative and quantitative disclosures are required. Effective January 1, 2018, the Partnership adopted the requirements of ASC 606 to new and existing contracts not yet completed as of January 1, 2018, using the modified retrospective approach where the cumulative effect of initially applying the standard is recorded as an adjustment to the opening balance of equity. The Partnership made an assessment on the various implementation aspects of ASU 2014-09 and its amendments, and since there are no changes to the timing or amount of revenue recognized, the Partnership has concluded that the effect of the implementation of this new standard will cause no material cumulative effect to the Partnership's historical or future financial position, results of operations or cash flows.

        In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Partnership adopted this ASU prospectively from January 1, 2018. As a result, this increases the likelihood that future dropdowns of Vessels may be considered the acquisition of an asset rather than a business combination.

        On March 1, 2018, the partnership's wholly owned subsidiary, KNOT Shuttle tankers AS, acquired KNOT's 100% interest in KNOT Shuttle Tankers 30 AS ("KNOT 30"), the company that owns and operates the Anna Knutsen. Following the adoption of ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, the Partnership accounted for this acquisition as an acquisition of an asset. The cost of the group of assets acquired in the asset acquisition has been allocated to the individual assets acquired or liabilities assumed based on their relative fair values. See the Note 21—Acquisitions.

        In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The new guidance clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The Partnership adopted this ASU on January 1, 2018. The Partnership's adoption of this standard did not have a material impact on the Partnership's consolidated statement of cash flows or related disclosures.

        In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash, which requires that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts presented on the statement of cash flows. The standard eliminates the presentation of transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. Additional disclosures are required for the nature of the restricted cash and restricted cash equivalents. The Partnership adopted this ASU on January 1, 2018 under a retrospective approach. The Partnership's adoption of this standard did not have a material impact on the Partnership's consolidated statement of cash flows or related disclosures.

        There are no other recent accounting pronouncements, whose adoption had a material impact on the consolidated financial statements in the current year.

        In February 2016, the FASB issued ASU 2016-02, Leases (ASC 842). The objective is to establish the principles that lessors and lessees shall apply to report useful information to users of financial statements about the amount, timing and uncertainty of cash flows arising from a lease. The Partnership is the lessor for its Vessels that operate on time charters and bareboat charters. Accounting by a lessor is largely unchanged from the previous standard. The Partnership does not have any material leased assets. A lessee will be required to recognize in its balance sheet a lease liability to make lease payments and a right-of-use asset. The standard requires a modified retrospective transition method for all entities and the standard provides for optional practical expedients in implementing the standard under the modified retrospective approach.

        In July 2018, the FASB issued targeted improvements to the leasing guidance allowing for an additional optional transition method that allow entities to initially apply the new lease standard and its disclosures at the transition date and recognize a cumulative-effect adjustment to the opening balance of retained earnings. The Partnership has elected to use this optional transition approach. The standard is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. The Partnership will adopt ASC 842 and implement the revised guidance as of January 1, 2019. The Partnership will apply the package of practical expedients, but not the hindsight practical expedients since the use of hindsight practical expedient only impacts lease classification if the package of practical expedients is not elected. The Partnership will not reassess whether any expired or existing contracts are, or contain leases, will not reassess lease classification, and will not reassess initial direct costs for any existing leases. Additionally, the practical expedient of disregarding short-term leases for agreements with lease terms of 12 months or less as a lessee and the expedient of not separating lease components from non-lease components will be used for all classes of underlying assets in the Partnership. Based upon assessments performed to date, the Partnership does not expect material effects on the accounting for existing leases applied in the consolidated financial statements where the Partnership is the lessor. Under ASU 2016-02, the Partnership will recognize a right-of-use asset and a lease liability on the balance sheet for certain leases where the Partnership is the lessee based on the present value of future minimum lease payments, whereas currently no right-of-use asset or lease liability is recognized. Based on the analysis performed by the Partnership to date, the right of use asset and lease liability to be recognized on January 1, 2019 is expected not to be material.

        Not applicable.

General

        Our partnership agreement provides that our general partner irrevocably delegates to our board of directors the authority to oversee and direct our operations, management and policies on an exclusive basis, and such delegation is binding on any successor general partner of the Partnership. Our general partner, KNOT Offshore Partners GP LLC, is wholly owned by KNOT. Our officers manage our day-to-day activities consistent with the policies and procedures adopted by our board of directors.

        Our current board of directors consists of seven members, Trygve Seglem, Richard Beyer, Takuji Banno, Hans Petter Aas, Edward A. Waryas, Jr., Andrew Beveridge and Simon Bird. Mr. Seglem, Mr. Beyer and Mr. Bannno and have been appointed by our general partner. Mr. Aas, Mr. Waryas, Mr. Beveridge and Mr. Bird were elected by our common unitholders. Directors appointed by our general partner serve as directors for terms determined by our general partner. Directors elected by our common unitholders are divided into four classes serving staggered four-year terms. Mr. Beveridge is designated as the Class II elected director and will serve until our annual meeting of unitholders in 2019, Mr. Bird is designated as our Class III elected director and will serve until our annual meeting of unitholders in 2020, Mr. Aas is designated as our Class IV elected director and will serve until our annual meeting of unitholders in 2021. Mr. Waryas is designated as the Class I elected director and will serve until our annual meeting of unitholders in 2022. At each annual meeting of unitholders, directors will be elected to succeed the class of director whose term has expired by a plurality of the votes of the common unitholders. Directors elected by our common unitholders will be nominated by our board of directors or by any limited partner or group of limited partners that holds at least 10% of the outstanding common units.

        Each outstanding common unit is entitled to one vote on matters subject to a vote of common unitholders. However, if at any time, any person or group owns beneficially more than 4.9% or more of any class of units then outstanding (excluding units held by Norwegian Resident Holders in the election of the elected directors as discussed below), any such units owned by that person or group in excess of 4.9% may not be voted (except for purposes of nominating a person for election to our board of directors). The voting rights of any such unitholders in excess of 4.9% will effectively be redistributed pro rata among the other common unitholders holding less than 4.9% of the voting power of such class of units. Our general partner, its affiliates and persons who acquire common units with the prior approval of our board of directors are not subject to this 4.9% limitation except with respect to voting their common units in the election of the elected directors.

        In addition, common unitholders that are Norwegian Resident Holders will not be eligible to vote in the election of the elected directors. The voting rights of any Norwegian Resident Holders will effectively be redistributed pro rata among the remaining common unitholders (subject to the limitation described above for 4.9% common unitholders) in these elections.

        The Series A Preferred Units do not have any right to nominate, appoint or elect any member of our board of directors unless distributions payable on the Series A Preferred Units have not been declared and paid for four consecutive quarters (a "Trigger Event"). Upon a Trigger Event, holders of Series A Preferred Units together with the holders of any other series of preferred units upon which like rights have been conferred and are exercisable, will have the right to replace one of the board members appointed by our general partner with a person nominated by such holders, such nominee to serve until all accrued and unpaid distributions on the preferred units have been paid.

Committees

        We have an audit committee that, among other things, reviews our external financial reporting, engages our external auditors and oversees our internal audit activities and procedures and the

98


Table of Contents

adequacy of our internal accounting controls. Our audit committee is comprised of Hans Petter Aas, Andrew Beveridge and Edward A. Waryas, Jr. Our board of directors has determined that each of Mr. Aas, Mr. Beveridge and Mr. Waryas satisfies the independence standards established by the NYSE. Mr. Aas qualifies as an "audit committee financial expert" for purposes of SEC rules and regulations.

        We also have a conflicts committee comprised of Mr. Waryas and Mr. Aas. The conflicts committee is available at our board of directors' discretion to review specific matters that our board of directors believes may involve conflicts of interest. The conflicts committee may determine if the resolution of the conflict of interest is fair and reasonable to us. The members of the conflicts committee may not be officers or employees of us or directors, officers or employees of our general partner or its affiliates and must meet the independence standards established by the NYSE to serve on an audit committee of a board of directors and certain other requirements. Any matters approved by the conflicts committee will be conclusively deemed to be fair and reasonable to us, approved by all of our partners and not a breach by our directors, our general partner or its affiliates of any duties any of them may owe us or our unitholders.

Exemptions from NYSE Corporate Governance Rules

        Because we qualify as a foreign private issuer under SEC rules, we are permitted to follow the corporate governance practices of the Marshall Islands (the jurisdiction in which we are organized) in lieu of certain of the NYSE corporate governance requirements that would otherwise be applicable to us. The NYSE rules do not require a listed company that is a foreign private issuer to have a board of directors that is comprised of a majority of independent directors. Under Marshall Islands law, we are not required to have a board of directors comprised of a majority of directors meeting the independence standards described in the NYSE rules. In addition, the NYSE rules do not require limited partnerships like us to have boards of directors comprised of a majority of independent directors. The NYSE rules do not require foreign private issuers or limited partnerships like us to establish a compensation committee or a nominating/corporate governance committee.

        Similarly, under Marshall Islands law, we are not required to have a compensation committee or a nominating/corporate governance committee. Accordingly, we do not have a compensation committee or a nominating/corporate governance committee. For a listing and further discussion of how our corporate governance practices differ from those required of U.S. companies listed on the NYSE, please read "Item 16G. Corporate Governance."

        Employees of affiliates of KNOT provide services to our subsidiaries pursuant to the technical management agreements, the management and administration agreements and the administrative services agreement. As of December 31, 2018, we directly employed one onshore employee and no seagoing employees. As of December 31, 2018, KNOT, through subsidiaries and affiliated companies, employed approximately 502 seagoing staff to serve on our vessels. Certain affiliates of KNOT, including KNOT Management, provide commercial and technical management services, including all necessary crew-related services, to our subsidiaries pursuant to the technical management agreements and the management and administration agreements.

        Each outstanding common unit is entitled to one vote on matters subject to a vote of common unitholders. However, if at any time, any person or group owns beneficially more than 4.9% or more of any class of units then outstanding (excluding units held by Norwegian Resident Holders in the election of the elected directors as discussed below), any such units owned by that person or group in excess of 4.9% may not be voted (except for purposes of nominating a person for election to our board of directors). The voting rights of any such unitholders in excess of 4.9% will effectively be redistributed pro rata among the other common unitholders holding less than 4.9% of the voting power of such class of units. Our general partner, its affiliates and persons who acquire common units with the prior approval of our board of directors are not subject to this 4.9% limitation except with respect to voting their common units in the election of the elected directors.

        In addition, common unitholders that are Norwegian Resident Holders will not be eligible to vote in the election of the elected directors. The voting rights of any Norwegian Resident Holders will

effectively be redistributed pro rata among the remaining common unitholders (subject to the limitation described above for 4.9% common unitholders) in these elections.

        As of April 10, 2019, we had 3,750,000 Series A Preferred Units issued and outstanding, of which 2,083,333 units, 1,250,000 units and 416,677 units are held by OMP AY Preferred Limited, Pierfront Capital Mezzanine Fund Pte. Ltd. and Tortoise Direct Opportunities Fund, LP., respectively.

Upon a Trigger Event, holders of Series A Preferred Units together with the holders of any other series of preferred units upon which like rights have been conferred and are exercisable, will have the right to replace one of the board members appointed by our general partner with a person nominated by such holders, such nominee to serve until all accrued and unpaid distributions on the preferred units have been paid. The Series A Preferred Units are entitled to vote with our common units as a single class, so that the Series A Preferred Units are entitled to one vote for each common unit into which the Series A Preferred Units are convertible at the time of voting. The 4.9% limitation described above applies to the holders of the Series A Preferred Units with respect to the voting of the Series A Preferred Units on an as-converted basis with the common units.

        KNOT exercises influence over the Partnership through our general partner, a wholly owned subsidiary of KNOT, which in its sole discretion appoints three directors to our board of directors. Please read "Item 6. Directors, Senior Management and Employees—Board Practices." KNOT also exercises influence over the Partnership through its ownership of 26.5% of our common units as of April 10, 2019.

        From time to time we have entered into agreements and have consummated transactions with certain related parties. We may enter into related party transactions from time to time in the future. In connection with our IPO, we established a conflicts committee, comprised entirely of independent directors, which must approve all proposed material related party transactions. The related party transactions that we have entered into or were party to since January 1, 2016 are discussed below.

Omnibus Agreement

        Upon the closing of our IPO, we entered into an Omnibus Agreement with KNOT, our general partner and certain of our other subsidiaries. The following discussion describes certain provisions of the Omnibus Agreement.

        Pursuant to the Omnibus Agreement, KNOT agreed, and caused its controlled affiliates (other than us, our general partner and our subsidiaries) to agree, not to acquire, own, operate or charter any shuttle tanker operating under a charter for five or more years. For purposes of this section, we refer to these vessels, together with any related charters, as "Five-Year Vessels" and to all other shuttle tankers, together with any related charters, as "Non-Five-Year Vessels." The restrictions in this paragraph do not prevent KNOT or any of its controlled affiliates (other than us and our subsidiaries) from:

101


Table of Contents

        If KNOT or any of its controlled affiliates (other than us or our subsidiaries) acquires, owns, operates or charters Five-Year Vessels pursuant to any of the exceptions described above, it may not subsequently expand that portion of its business other than pursuant to those exceptions. However, such Five-Year Vessels could eventually compete with our vessels upon their re-chartering.

        In addition, pursuant to the Omnibus Agreement, we agree, and cause our subsidiaries to agree, to acquire, own, operate or charter Five-Year Vessels only. The restrictions in this paragraph do not:

102


Table of Contents

        If we or any of our subsidiaries acquires, owns, operates or charters Non-Five-Year Vessels pursuant to any of the exceptions described above, neither we nor such subsidiary may subsequently expand that portion of our business other than pursuant to those exceptions.

        Upon a change of control of us or our general partner, the noncompetition provisions of the Omnibus Agreement terminate immediately. Upon a change of control of KNOT, the noncompetition provisions of the Omnibus Agreement applicable to KNOT terminate at the time of the change of control. On the date on which a majority of our directors ceases to consist of directors that were (1) appointed by our general partner prior to our first annual meeting of unitholders and (2) recommended for election by a majority of our appointed directors, the noncompetition provisions applicable to KNOT terminate immediately.

        Pursuant to the Omnibus Agreement, we and our subsidiaries granted to KNOT a right of first offer on any proposed sale, transfer or other disposition of any Five-Year Vessels or Non-Five-Year Vessels owned by us. Pursuant to the Omnibus Agreement, KNOT agreed, and caused its subsidiaries to agree, to grant a similar right of first offer to us for any Five-Year Vessels they might own. These rights of first offer do not apply to a (1) sale, transfer or other disposition of vessels between any affiliated subsidiaries or pursuant to the terms of any current or future charter or other agreement with a charterparty or (2) merger with or into, or sale of substantially all of the assets to, an unaffiliated third party.

        Prior to engaging in any negotiation regarding any vessel disposition with respect to a Five-Year Vessel with an unaffiliated third party or any Non-Five-Year Vessel, we or KNOT, as the case may be, will deliver a written notice to the other relevant party setting forth the material terms and conditions of the proposed transaction. During the 30-day period after the delivery of such notice, we and KNOT, as the case may be, will negotiate in good faith to reach an agreement on the transaction. If we do not

103


Table of Contents

reach an agreement within such 30-day period, we or KNOT, as the case may be, will be able within the next 180 calendar days to sell, transfer, dispose or re-charter the vessel to a third party (or to agree in writing to undertake such transaction with a third party) on terms generally no less favorable to us or KNOT, as the case may be, than those offered pursuant to the written notice.

        Upon a change of control of us or our general partner, the right-of-first-offer provisions of the Omnibus Agreement terminate immediately. Upon a change of control of KNOT, the right-of-first-offer provisions applicable to KNOT pursuant to the Omnibus Agreement terminate at the time of the change of control. On the date on which a majority of our directors ceases to consist of directors that were (1) appointed by our general partner prior to our first annual meeting of unitholders and (2) recommended for election by a majority of our appointed directors, the provisions related to the rights of first offer granted to us by KNOT terminate immediately.

        Pursuant to the Omnibus Agreement, KNOT indemnified us until April 15, 2018 (and KNOT indemnifies us for a period of at least three years after our purchase of the Hilda Knutsen, the Torill Knutsen, the Ingrid Knutsen and the Raquel Knutsen, as applicable) against certain environmental and toxic tort liabilities with respect to the assets contributed or sold to us to the extent arising prior to the time they were contributed or sold to us. Liabilities resulting from a change in law after the closing of our IPO are excluded from the environmental indemnity. There is an aggregate cap of $5 million on the amount of indemnity coverage provided by KNOT for environmental and toxic tort liabilities. No claim may be made unless the aggregate U.S. Dollar amount of all claims exceeds $500,000, in which case KNOT is liable for claims only to the extent such aggregate amount exceeds $500,000.

        KNOT also indemnifies us for liabilities related to:

        The Omnibus Agreement may not be amended without the prior approval of the conflicts committee of our board of directors if the proposed amendment will, in the reasonable discretion of our board of directors, adversely affect holders of our common units.

        If at any time until April 15, 2018, the Bodil Knutsen was not receiving from any charterer a hire rate equal to or greater than the hire rate payable under the initial Bodil Knutsen charter, then KNOT was required to pay us such hire rate that would have been in effect and payable under the initial Bodil Knutsen charter; provided, however, that in the event that, if at any time until April 15, 2018, the Bodil Knutsen was chartered under a charter other than the initial Bodil Knutsen charter and the hire rate being paid under such charter was lower than the hire rate that would have been in effect and payable under the initial Bodil Knutsen charter during any such period, then KNOT was required to pay us the difference between the hire rate that would have been in effect and payable under the initial Bodil

104


Table of Contents

Knutsen charter during such period and the hire rate then in effect and payable under such other charter.

        If at any time until April 15, 2018, the Windsor Knutsen was not receiving from any charterer a hire rate that is equal to or greater than the hire rate payable under the initial Windsor Knutsen charter, then KNOT was required to pay us such hire rate that would have been in effect and payable under the initial Windsor Knutsen charter; provided, however, that in the event that, if at any time until April 15, 2018, the Windsor Knutsen was chartered under a charter other than the initial Windsor Knutsen charter and the hire rate being paid under such charter was lower than the hire rate that would have been in effect and payable under the initial Windsor Knutsen charter during any such period, then KNOT was required to pay us the difference between the hire rate that would have been in effect and payable under the initial Windsor Knutsen charter during such period and the hire rate then in effect and payable under such other charter; provided, further, that the hire rate that would have been in effect and payable under the initial Windsor Knutsen charter during the period between the final termination date of the initial Windsor Knutsen charter (assuming that all extension options thereunder would have been exercised) and the last day of the five-year period following the closing date of our IPO was be deemed to have been the hire rate that would have been in effect and payable during the last option extension period under the initial Windsor Knutsen charter (assuming that all extension options thereunder would have been exercised).

Windsor Knutsen Charter with Knutsen Shuttle Tankers Pool AS

        On December 17, 2018, our subsidiary that owns the Windsor Knutsen, KNOT Shuttle Tankers 18 AS, entered into a time charter contract with Knutsen Shuttle Tankers Pool AS, a wholly owned subsidiary of KNOT. Under the time charter contract with Knutsen Shuttle Tankers Pool AS, the Windsor Knutsen will operate on the same terms as its existing time charter contract with Shell during the 10 to 12 month period that the time charter contract with Shell is suspended. The suspension period under the time charter contract with Shell commenced March 4, 2019.

Administrative Services Agreement

        Effective as of February 26, 2013, in connection with our IPO, we entered into an administrative services agreement with KNOT UK, pursuant to which KNOT UK provides certain management and administrative services to us. The agreement had an initial term of five years. The services provided under the administrative services agreement are provided in a diligent manner, as we may reasonably direct. KNOT UK is permitted to subcontract certain of the administrative services provided under this agreement to KOAS UK and KOAS, each of which is a wholly owned subsidiary of TSSI and KNOT Management. On May 7, 2015, we entered into an amendment to the administrative services agreement, which allows KNOT UK to also subcontract administrative services to KNOT Management. Effective as of February 26, 2018, we entered into a second amendment to the administrative services agreement extending the term of the agreement indefinitely.

        The administrative services agreement may be terminated by any party upon 90 days' notice for any reason. Under the administrative services agreement, John Costain, as an officer of KNOT UK, provides executive officer functions for our benefit. Mr. Costain is responsible for our day-to-day management subject to the direction of our board of directors. Our board of directors has the ability to terminate the arrangement with KNOT UK regarding the provision of executive officer services to us with respect to Mr. Costain at any time in its sole discretion. Beginning on June 1, 2019, Gary Chapman will provide executive officer services for our benefit as an officer of KNOT UK under the administrative services agreement. Mr. Chapman will be responsible for our day-to-day management subject to the direction of our board of directors. Our board of directors will have the ability to terminate the agreement with KNOT UK regarding the provision of executive officer services to us with respect to Mr. Chapman at any time in its sole discretion.

In addition, included in trade accounts payable, trading balances due to KOAS were $0.4 million and trading balances due to KNOT were $0.5 million for the year ended December 31, 2018. Outstanding balances are settled on a monthly basis.

        As a result of our relationships with KNOT and its affiliates, we, our general partner and our subsidiaries have entered into various agreements that were not the result of arm's length negotiations. We generally refer to these agreements and the transactions that they provide for as "affiliated transactions" or "related party transactions."

        Our partnership agreement sets forth procedures by which future related party transactions may be approved or resolved by our board of directors. Pursuant to our partnership agreement, our board of

110


Table of Contents

directors may, but is not required to, seek the approval of a related party transaction from the conflicts committee of our board of directors or from the common unitholders. Affiliated transactions that are not approved by the conflicts committee of our board of directors and that do not involve a vote of unitholders must be on terms no less favorable to us than those generally provided to or available from unrelated third parties or be "fair and reasonable" to us. In determining whether a transaction or resolution is "fair and reasonable," our board of directors may consider the totality of the relationships between the parties involved, including other transactions that may be particularly advantageous or beneficial to us. If the above procedures are followed, it will be presumed that, in making its decision, our board of directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the Partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption. When our partnership agreement requires someone to act in good faith, it requires that person to reasonably believe that he is acting in the best interests of the Partnership, unless the context otherwise requires.

        Our conflicts committee is comprised of at least two members of our board of directors. The conflicts committee is available at our board of directors' discretion to review specific matters that our board of directors believes may involve conflicts of interest. The conflicts committee may determine if the resolution of the conflict of interest is fair and reasonable to us. The members of the conflicts committee may not be officers or employees of us or directors, officers or employees of our general partner or its affiliates, and must meet the independence standards established by the NYSE to serve on an audit committee of a board of directors and certain other requirements.

Distributions to KNOT

        We have declared and paid quarterly distributions totaling $22.1 million and $21.8 million to KNOT for each of the years ended December 31, 2018 and 2017, respectively.

        Not applicable.

Item 8.    Financial Information

        Please read "Item 18. Financial Statements" for additional information required to be disclosed under this item.

Legal Proceedings

        From time to time we have been, and expect to continue to be, subject to legal proceedings and claims in the ordinary course of our business, principally personal injury and property casualty claims. These claims, even if lacking merit, could result in the expenditure of significant financial and managerial resources. We are not aware of any legal proceedings or claims that we believe will have, individually or in the aggregate, a material adverse effect on us.

Our Cash Distribution Policy

        Our cash distribution policy reflects a judgment that our unitholders will be better served by our distributing our available cash (after deducting expenses, including estimated maintenance and replacement capital expenditures and reserves) rather than retaining it. Because we believe we will generally finance any expansion capital expenditures from external financing sources, we believe that our investors are best served by our distributing all of our available cash. Our cash distribution policy is

111


Table of Contents

consistent with the terms of our partnership agreement, which requires that we distribute all of our available cash quarterly (after deducting expenses, including estimated maintenance and replacement capital expenditures and reserves).

        There is no guarantee that unitholders will receive quarterly distributions from us. Our distribution policy is subject to certain restrictions and may be changed at any time, including:

112


Table of Contents

        Our ability to make cash distributions to our unitholders depends on the performance of our subsidiaries and their ability to distribute cash to us. The ability of our subsidiaries to make distributions to us may be restricted by, among other things, the provisions of existing and future indebtedness, applicable limited partnership and limited liability company laws in the Marshall Islands and Norway and other laws and regulations.

        The Series A Preferred Units rank senior to the common units as to the payment of distributions and amounts payable upon liquidation, dissolution or winding up. The Series A Preferred Units have a liquidation preference of $24.00 per unit, plus any unpaid Series A cash distributions, plus all accrued but unpaid distributions on such Series A Preferred Unit with respect to the quarter in which the liquidation occurs to the date fixed for the payment of any amount upon liquidation. The Series A Preferred Units are entitled to cumulative distributions from their initial issuance date, with distributions being calculated at an annual rate of 8.0% on the stated liquidation preference and payable quarterly in arrears within 45 days after the end of each quarter, when, as and if declared by the board of directors of the Partnership.

        During the year ended December 31, 2018, the aggregate amount of cash distributions paid to the holders of the Series A Preferred Units was $7.2 million.

        Common unitholders are entitled under our partnership agreement to receive a minimum quarterly distribution of $0.375 per unit to the extent we have sufficient cash on hand to pay the distribution, after establishment of cash reserves, distribution payments on the Series A Preferred Units and payment of fees and expenses. There is no guarantee that we will pay the minimum quarterly distribution on the common units in any quarter. Even if our cash distribution policy is not modified or revoked, the amount of distributions paid under our policy and the decision to make any distribution is determined by our board of directors, taking into consideration the terms of our partnership agreement. We are prohibited from making any distributions to unitholders if it would cause an event of default, or an event of default is then existing, under our financing agreements. Please read "Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources" for a discussion of the restrictions contained in our credit facilities and lease arrangements that may restrict our ability to make cash distributions to our unitholders.

        During the year ended December 31, 2018, the aggregate amount of cash distributions paid to common unitholders was $70.8 million.

        Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels have been achieved. KNOT currently holds the incentive distribution rights. The incentive distribution rights may be transferred separately from any other interest, subject to restrictions in our partnership agreement. Any transfer by KNOT of the incentive distribution rights would not change the percentage allocations of quarterly distributions with respect to such rights.

Table of Contents

        The following table illustrates the percentage allocations of the additional available cash from operating surplus among our unitholders, our general partner and the holders of the incentive distribution rights up to the various target distribution levels. The amounts set forth under "Marginal Percentage Interest in Distributions" are the percentage interests of our unitholders, our general partner and the holders of the incentive distribution rights in any available cash from operating surplus we distribute up to and including the corresponding amount in the column "Total Quarterly Distribution Target," until available cash from operating surplus we distribute reaches the next target distribution level, if any. The percentage interests shown for our unitholders, our general partner and the holders of the incentive distribution rights for the minimum quarterly distribution are also applicable to quarterly distributions that are less than the minimum quarterly distribution. The percentage interests set forth in the table below assume that our general partner owns a 1.85% general partner interest and that we do not issue additional classes of equity securities.

        We are not aware of any governmental laws, decrees, regulations or other legislation, including foreign exchange controls, in the Republic of the Marshall Islands that may affect the import or export of capital, including the availability of cash and cash equivalents for use by the Partnership, or the remittance of dividends, interest or other payments to non-resident holders of our securities.

        The following is a discussion of the material U.S. federal income tax considerations that may be relevant to current and prospective unitholders. This discussion is based upon provisions of the Code, Treasury Regulations and current administrative rulings and court decisions, all as in effect or existence on the date of this Annual Report and all of which are subject to change, possibly with retroactive effect. Changes in these authorities may cause the tax consequences of unit ownership to vary substantially from the consequences described below. Unless the context otherwise requires, references in this section to "we," "our" or "us" are references to KNOT Offshore Partners LP.

        The following discussion applies only to beneficial owners of common units that own the common units as "capital assets" within the meaning of Section 1221 of the Code (i.e., generally, for investment purposes) and is not intended to be applicable to all categories of investors, such as unitholders subject to special tax rules (e.g., financial institutions, insurance companies, broker-dealers, tax-exempt organizations, retirement plans, individual retirement accounts, persons who own (actually or constructively) 10% or more of the vote or value of our equity or former citizens or long-term residents of the United States), persons who hold the units as part of a straddle, conversion, constructive sale or other integrated transaction for U.S. federal income tax purposes, or persons that have a functional currency other than the U.S. Dollar, each of whom may be subject to tax rules that differ significantly from those summarized below. If a partnership or other entity classified as a partnership for U.S. federal income tax purposes holds our common units, the tax treatment of its partners generally will depend upon the status of the partner and the activities of the partnership. If you are a partner in a partnership holding our common units, you should consult your own tax advisor regarding the tax consequences to you of the partnership's ownership of our common units.

        No ruling has been or will be requested from the IRS regarding any matter affecting us or current and prospective unitholders. The statements made herein may be challenged by the IRS and, if so challenged, may not be sustained upon review in a court.

        This discussion does not contain information regarding any U.S. state or local, estate, gift or alternative minimum tax considerations concerning the ownership or disposition of common units. This discussion does not comment on all aspects of U.S. federal income taxation that may be important to particular unitholders in light of their individual circumstances, and each prospective unitholder is urged to consult its own tax advisor regarding the U.S. federal, state, local and other tax consequences of the ownership or disposition of common units.

Election to be Treated as a Corporation

        We have elected to be treated as a corporation for U.S. federal income tax purposes. As a result, U.S. Holders (as defined below) will not be directly subject to U.S. federal income tax on our income, but rather will be subject to U.S. federal income tax on distributions received from us and dispositions of units as described below.

U.S. Federal Income Taxation of U.S. Holders

        As used herein, the term "U.S. Holder" means a beneficial owner of our common units that is:

        Subject to the discussion below of the rules applicable to PFICs, any distributions to a U.S. Holder made by us with respect to our common units generally will constitute dividends to the extent of our current and accumulated earnings and profits, as determined under U.S. federal income tax principles. If we make distributions to U.S. Holders in excess of our earnings and profits, the excess portion of those distributions will be treated first as a nontaxable return of capital to the extent of the U.S. Holder's tax basis in its common units and thereafter as capital gain. U.S. Holders that are corporations generally will not be entitled to claim a dividends-received deduction with respect to distributions that they receive from us. Dividends received with respect to our common units generally will be treated as "passive category income" for purposes of computing allowable foreign tax credits for U.S. federal income tax purposes.

        Dividends received with respect to our common units by a U.S. Holder that is an individual, trust or estate (a "U.S. Individual Holder") generally will be treated as "qualified dividend income," which is taxable to such U.S. Individual Holder at preferential tax rates provided that: (1) our common units are readily tradable on an established securities market in the United States (such as the NYSE, on which our common units are traded); (2) we are not a PFIC for the taxable year during which the dividend is paid or the immediately preceding taxable year (which we do not believe we are, have been or will be, as discussed below under "—PFIC Status and Significant Tax Consequences"); (3) the U.S. Individual Holder has owned the common units for more than 60 days during the 121-day period beginning 60 days before the date on which the common units become ex-dividend (and has not entered into certain risk limiting transactions with respect to such common units); and (4) the U.S. Individual Holder is not under an obligation to make related payments with respect to positions in substantially similar or related property. Because of the uncertainty of these matters, including whether we are or will be a PFIC, there is no assurance that any dividends paid on our common units will be eligible for these preferential rates in the hands of a U.S. Individual Holder, and any dividends paid on our common units that are not eligible for these preferential rates will be taxed as ordinary income to a U.S. Individual Holder.

        Special rules may apply to any amounts received in respect of our common units that are treated as "extraordinary dividends." In general, an extraordinary dividend is a dividend with respect to a common unit that is equal to or in excess of 10% of a unitholder's adjusted tax basis (or fair market value upon the unitholder's election) in such common unit. In addition, extraordinary dividends include dividends received within a one-year period that, in the aggregate, equal or exceed 20% of a unitholder's adjusted tax basis (or fair market value). If we pay an "extraordinary dividend" on our common units that is treated as "qualified dividend income," then any loss recognized by a U.S. Individual Holder from the sale or exchange of such common units will be treated as long-term capital loss to the extent of the amount of such dividend.

119


Table of Contents

        Subject to the discussion of PFIC status below, a U.S. Holder generally will recognize capital gain or loss upon a sale, exchange or other taxable disposition of our units in an amount equal to the difference between the amount realized by the U.S. Holder from such sale, exchange or other taxable disposition and the U.S. Holder's adjusted tax basis in such units. The U.S. Holder's initial tax basis in its units generally will be the U.S. Holder's purchase price for the units and that tax basis will be reduced (but not below zero) by the amount of any distributions on the units that are treated as non-taxable returns of capital (as discussed above under "—Distributions"). Such gain or loss will be treated as long-term capital gain or loss if the U.S. Holder's holding period is greater than one year at the time of the sale, exchange or other taxable disposition. Certain U.S. Holders (including individuals) may be eligible for preferential rates of U.S. federal income tax in respect of long-term capital gains. A U.S. Holder's ability to deduct capital losses is subject to limitations. Any such capital gain or loss generally will be treated as U.S. source income or loss, as applicable, for U.S. foreign tax credit purposes.

        Certain U.S. Holders, including individuals, estates and trusts, will be subject to an additional 3.8% Medicare tax on, among other things, dividends and capital gains from the sale or other disposition of equity interests. For individuals, the additional Medicare tax applies to the lesser of (1) "net investment income" or (2) the excess of "modified adjusted gross income" over $200,000 ($250,000 if married and filing jointly or $125,000 if married and filing separately). "Net investment income" generally equals the taxpayer's gross investment income reduced by deductions that are allocable to such income. Unitholders should consult their tax advisors regarding the implications of the additional Medicare tax resulting from their ownership and disposition of our common units.

        Adverse U.S. federal income tax rules apply to a U.S. Holder that owns an equity interest in a non-U.S. corporation that is classified as a PFIC for U.S. federal income tax purposes. In general, we will be treated as a PFIC with respect to a U.S. Holder if, for any taxable year in which the holder held our units, either:

        Income earned, or treated as earned (for U.S. federal income tax purposes), by us in connection with the performance of services would not constitute passive income. By contrast, rental income generally would constitute "passive income" unless we were treated as deriving that rental income in the active conduct of a trade or business under the applicable rules.

        Based on our current and projected methods of operation, we believe that we were not a PFIC for any prior taxable year, and we expect that we will not be treated as a PFIC for the current or any future taxable year. We believe that more than 25% of our gross income for each taxable year was or will be non-passive income, and more than 50% of the average value of our assets for each such year was or will be held for the production of non-passive income. This belief is based on certain valuations and projections regarding our income and assets, and its validity is based on the accuracy of such

120


Table of Contents

valuations and projections. While we believe these valuations and projections to be accurate, the shipping market is volatile and no assurance can be given that they will continue to be accurate at any time in the future.

        Moreover, there are legal uncertainties involved in determining whether the income derived from time-chartering activities constitutes rental income or income derived from the performance of services. In Tidewater Inc. v. United States, 565 F.3d 299 (5th Cir. 2009), the Fifth Circuit held that income derived from certain time-chartering activities should be treated as rental income rather than services income for purposes of a provision of the Code relating to foreign sales corporations. In that case, the Fifth Circuit did not address the definition of passive income or the PFIC rules; however, the reasoning of the case could have implications as to how the income from a time charter would be classified under such rules. If the reasoning of the case were extended to the PFIC context, the gross income we derive from our time-chartering activities may be treated as rental income, and we would likely be treated as a PFIC. In published guidance, the IRS stated that it disagreed with the holding in Tidewater and specified that time charters similar to those at issue in this case should be treated as service contracts.

        Distinguishing between arrangements treated as generating rental income and those treated as generating services income involves weighing and balancing competing factual considerations, and there is no legal authority under the PFIC rules addressing our specific method of operation. Conclusions in this area therefore remain matters of interpretation. We are not seeking a ruling from the IRS on the treatment of income generated from our time-chartering operations. Thus, it is possible that the IRS or a court could disagree with our position. In addition, although we intend to conduct our affairs in a manner to avoid being classified as a PFIC with respect to any taxable year, we cannot assure unitholders that the nature of our operations will not change in the future and that we will not become a PFIC in any future taxable year.

        As discussed more fully below, if we were to be treated as a PFIC for any taxable year (and regardless of whether we remain a PFIC over the subsequent taxable years), a U.S. Holder would be subject to different taxation rules depending on whether the U.S. Holder makes an election to treat us as a "Qualified Electing Fund," which we refer to as a "QEF election." As an alternative to making a QEF election, a U.S. Holder should be able to make a "mark-to-market" election with respect to our common units, as discussed below. In addition, if a U.S. Holder owns our common units during any taxable year that we are a PFIC, such holder must file an annual report with the IRS.

        If a U.S. Holder makes a timely QEF election (or an Electing Holder), then, for U.S. federal income tax purposes, that holder must report as income for its taxable year its pro rata share of our ordinary earnings and net capital gain, if any, for our taxable years that end with or within the taxable year for which that holder is reporting, regardless of whether or not the Electing Holder received distributions from us in that year. The Electing Holder's adjusted tax basis in the common units will be increased to reflect taxed but undistributed earnings and profits.

        Distributions of earnings and profits that were previously taxed will result in a corresponding reduction in the Electing Holder's adjusted tax basis in common units and will not be taxed again once distributed. An Electing Holder generally will recognize capital gain or loss on the sale, exchange or other disposition of our common units. A U.S. Holder makes a QEF election with respect to any year that we are a PFIC by filing IRS Form 8621 with its U.S. federal income tax return. If contrary to our expectations, we determine that we are treated as a PFIC for any taxable year, we will provide each U.S. Holder with the information necessary to make the QEF election described above. Although the QEF election is available with respect to subsidiaries, in the event we acquire or own a subsidiary in the future that is treated as a PFIC, no assurances can be made that we will be able to provide U.S. Holders with the necessary information to make the QEF election with respect to such subsidiary.

121


Table of Contents

        If we were to be treated as a PFIC for any taxable year in which a U.S. Holder holds our common units and, as we anticipate, our units were treated as "marketable stock," then, as an alternative to making a QEF election, a U.S. Holder would be allowed to make a "mark-to-market" election with respect to our common units, provided the U.S. Holder completes and files IRS Form 8621 in accordance with the relevant instructions and related Treasury Regulations. If that election is made, the U.S. Holder generally would include as ordinary income in each taxable year the excess, if any, of the fair market value of the U.S. Holder's common units at the end of the taxable year over the holder's adjusted tax basis in the common units. The U.S. Holder also would be permitted an ordinary loss in respect of the excess, if any, of the U.S. Holder's adjusted tax basis in the common units over the fair market value thereof at the end of the taxable year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. A U.S. Holder's tax basis in its common units would be adjusted to reflect any such income or loss recognized. Gain recognized on the sale, exchange or other disposition of our common units would be treated as ordinary income, and any loss recognized on the sale, exchange or other disposition of the common units would be treated as ordinary loss to the extent that such loss does not exceed the net mark-to-market gains previously included in income by the U.S. Holder. The mark-to-market election generally will not be available with respect to subsidiaries. Accordingly, in the event we acquire or own a subsidiary in the future that is treated as a PFIC, the mark-to-market election generally will not be available with respect to such subsidiary.

        If we were to be treated as a PFIC for any taxable year in which a U.S. Holder holds our common units, a U.S. Holder that does not make either a QEF election or a "mark-to-market" election for that year (or a Non-Electing Holder) would be subject to special rules resulting in increased tax liability with respect to (1) any excess distribution (i.e., the portion of any distributions received by the Non-Electing Holder on our common units in a taxable year in excess of 125% of the average annual distributions received by the Non-Electing Holder in the three preceding taxable years, or, if shorter, the Non-Electing Holder's holding period for the common units) and (2) any gain realized on the sale, exchange or other disposition of the units. Under these special rules:

        These penalties would not apply to a qualified pension, profit sharing or other retirement trust or other tax-exempt organization that did not borrow money or otherwise utilize leverage in connection with its acquisition of our common units. If we were treated as a PFIC for any taxable year and a Non-Electing Holder who is an individual dies while owning our common units, such holder's successor generally would not receive a step-up in tax basis with respect to such units.

U.S. Federal Income Taxation of Non-U.S. Holders

        A beneficial owner of our common units (other than a partnership or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not a U.S. Holder is referred to as a Non-U.S. Holder. If you are a partner in a partnership (or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holding our common units, you should consult your own tax advisor regarding the tax consequences to you of the partnership's ownership of our common units.

        Distributions we pay to a Non-U.S. Holder will not be subject to U.S. federal income tax or withholding tax if the Non-U.S. Holder is not engaged in a U.S. trade or business. If the Non-U.S. Holder is engaged in a U.S. trade or business, our distributions will be subject to U.S. federal income tax to the extent such distributions constitute income effectively connected with the Non-U.S. Holder's U.S. trade or business (provided, in the case of a Non-U.S. Holder entitled to the benefits of an income tax treaty with the United States, such distributions also are attributable to a U.S. permanent establishment). The after-tax amount of any effectively connected distributions received by a Non-U.S. Holder that is a corporation for U.S. federal income tax purposes may also be subject to an additional U.S. branch profits tax at a rate of 30% (or, if applicable, a lower treaty rate).

        In general, a Non-U.S. Holder is not subject to U.S. federal income tax or withholding tax on any gain resulting from the disposition of our common units provided the Non-U.S. Holder is not engaged in a U.S. trade or business. A Non-U.S. Holder that is engaged in a U.S. trade or business will be subject to U.S. federal income tax in the event the gain from the disposition of units is effectively connected with the conduct of such U.S. trade or business (provided, in the case of a Non-U.S. Holder entitled to the benefits of an income tax treaty with the United States, such gain also is attributable to a U.S. permanent establishment). The after-tax amount of any effectively connected gain of a Non-U.S. Holder that is a corporation for U.S. federal income tax purposes may also be subject to an additional U.S. branch profits tax at a rate of 30% (or, if applicable, a lower treaty rate). However, even if not engaged in a U.S. trade or business, individual Non-U.S. Holders may be subject to tax on gain resulting from the disposition of our common units if they are present in the United States for 183 days or more during the taxable year in which those units are disposed and they meet certain other requirements.

Backup Withholding and Information Reporting

        In general, payments to a non-corporate U.S. Holder of distributions or the proceeds of a disposition of common units will be subject to information reporting. These payments to a non-corporate U.S. Holder also may be subject to backup withholding if the non-corporate U.S. Holder:

        Non-U.S. Holders may be required to establish their exemption from information reporting and backup withholding by certifying their status on IRS Form W-8BEN, W-8BEN-E, W-8ECI or W-8IMY, as applicable.

123


Table of Contents

        Backup withholding is not an additional tax. Rather, a unitholder generally may obtain a credit for any amount withheld against its liability for U.S. federal income tax (and obtain a refund of any amounts withheld in excess of such liability) by timely filing a U.S. federal income tax return with the IRS.

        In addition, individual citizens or residents of the United States holding certain "foreign financial assets" (which generally includes stock and other securities issued by a foreign person unless held in an account maintained by a financial institution) that exceed certain thresholds (the lowest being holding foreign financial assets with an aggregate value in excess of: (1) $50,000 on the last day of the tax year or (2) $75,000 at any time during the tax year) are required to report information relating to such assets. Significant penalties may apply for failure to satisfy the reporting obligations described above. Unitholders should consult their tax advisors regarding their reporting obligations, if any, that would result from their purchase, ownership or disposition of our units.

Non-United States Tax Considerations

        Unless the context otherwise requires, references in this section to "we," "our" or "us" are references to KNOT Offshore Partners LP.

        Because we and our subsidiaries do not and do not expect to conduct business, transactions or operations in the Republic of the Marshall Islands, under current Marshall Islands law, unitholders that are neither citizens nor residents of the Marshall Islands and do not maintain offices in nor engage in business, transactions or operations in the Republic of the Marshall Islands will not be subject to Marshall Islands taxation or withholding on distributions, including upon distribution treated as a return of capital, we make to them as unitholders. In addition, such unitholders will not be subject to Marshall Islands stamp, capital gains or other taxes on the purchase, ownership or disposition of common units, and they will not be required by the Republic of the Marshall Islands to file Marshall Islands tax returns relating to their ownership of common units.

        Current and prospective unitholders who are resident in Norway for taxation purposes are urged to consult their own tax advisors regarding the potential Norwegian tax consequences to them of an investment in our common units. For this purpose, a company incorporated outside of Norway will be treated as resident in Norway in the event its central management and control is carried out in Norway.

        The discussion that follows is based upon existing Norwegian legislation and current Norwegian Tax Administration practice. Changes in these authorities may cause the tax consequences to vary substantially from the consequences of unit ownership described below. Unless the context otherwise requires, references in this section to "we," "our" or "us" are references to KNOT Offshore Partners LP.

        Under the Tax Act on Income and Wealth, persons not resident in Norway for taxation purposes ("Non-Norwegian Holders") will not be subject to any taxes in Norway on income or profits in respect of the acquisition, holding, disposition or redemption of the common units, provided that:

124


Table of Contents

        A Non-Norwegian Holder that carries on a business in Norway through a partnership is subject to Norwegian tax on income derived from the business if managed from Norway or carried on by the Partnership in Norway.

        While we expect to conduct our affairs in such a manner that our business will not be treated as managed from or carried on in Norway at any time in the future, this determination is dependent upon the facts existing at such time, including (but not limited to) the place where our board of directors meets and the place where our management makes decisions or takes certain actions affecting our business. Our Norwegian tax counsel has advised us regarding certain measures we can take to limit the risk that our business may be treated as managed from or carried on in Norway and has concluded that, provided we adopt these measures and otherwise conduct our affairs in a manner consistent with our Norwegian tax counsel's advice, which we intend to do, our business should not be treated as managed from or carried on in Norway for taxation purposes, and consequently, Non-Norwegian Holders should not be subject to tax in Norway solely by reason of the acquisition, holding, disposition or redemption of their common units. Nonetheless, there is no legal authority addressing our specific circumstances, and conclusions in this area remain matters of interpretation. Thus, it is possible that the Norwegian taxation authority could challenge, or a court could disagree with, our position.

        While we do not expect it to be the case, if the arrangements we propose to enter into result in our being considered to carry on business in Norway for the purposes of the Tax Act on Income and Wealth, unitholders would be considered to be carrying on business in Norway and would be required to file tax returns with the Norwegian Tax Administration and, subject to any relief provided in any relevant double taxation treaty (including, in the case of holders resident in the United States, the U.S.-Norway Tax Treaty), would be subject to taxation in Norway on any income considered to be attributable to the business carried on in Norway.

        The following is a discussion of the material United Kingdom tax consequences that may be relevant to prospective unitholders who are persons not resident in the United Kingdom for taxation purposes and who do not acquire their units as part of a trade, profession or vocation carried on in the United Kingdom, which we refer to as "Non-UK Holders."

        Prospective unitholders who are resident or domiciled in the United Kingdom for taxation purposes, or who hold their units through a trade, profession or vocation in the United Kingdom are urged to consult their own tax advisors regarding the potential United Kingdom tax consequences to them of an investment in our common units and are responsible for filing their own UK tax returns and paying any applicable UK taxes (which may be due on amounts received by us but not distributed). The discussion that follows is based upon current United Kingdom tax law and what is understood to be the current practice of HMRC as at the date of this document, both of which are subject to change, possibly with retrospective effect.

        Taxation of income and disposals.    We expect to conduct our affairs so that Non-UK Holders should not be subject to United Kingdom income tax, capital gains tax or corporation tax on income or gains arising from our partnership. Distributions may be made to Non-UK Holders without withholding or deduction for or on account of United Kingdom income tax.

        Stamp taxes.    No liability to United Kingdom stamp duty or stamp duty reserve tax should arise in connection with the issue of units to unitholders or the transfer of units in our partnership.

Item 11.    Quantitative and Qualitative Disclosures About Market Risk

        We are exposed to various market risks, including interest rate, foreign currency exchange rate and concentration of credit risks. Historically, we have entered into certain derivative instruments and contracts to maintain the desired level of exposure arising from interest rate and certain foreign currency exchange rate risks.

        Our policy is to economically hedge our exposure to risks, where possible, within boundaries deemed appropriate by management.

        A portion of our debt obligations and surplus funds placed with financial institutions are subject to movements in interest rates. It is our policy to obtain the most favorable interest rates available without increasing our foreign currency exposure. In keeping with this, our surplus funds may in the future be placed in fixed deposits with reputable financial institutions that yield better returns than bank deposits. The deposits generally have short-term maturities so as to provide us with the flexibility to meet working capital and capital investments.

        We have historically used interest rate swap contracts to manage our exposure to interest rate risks. Interest rate swap contracts were used to convert floating rate debt obligations based on LIBOR to a fixed rate in order to achieve an overall desired position of fixed and floating rate debt. The extent to which interest rate swap contracts are used is determined by reference to our net debt exposure and our views regarding future interest rates. Our interest rate swap contracts do not qualify for hedge accounting, and movements in their fair values are reflected in the statements of operations under "Realized and unrealized gain (loss) on derivative instruments." Interest rate swap contracts that have a positive fair value are recorded as "Other current assets," while swaps with a negative fair value are recorded as "Derivative liabilities."

        As of December 31, 2018, we were party to interest rate swap contracts with a combined notional amount of approximately $555.5 million. Under the terms of the interest rate swap contracts, we

126


Table of Contents

receive LIBOR-based variable interest rate payments and make fixed interest rate payments at fixed rates between 1.38% per annum and 2.89% per annum for all periods. The interest rate swap contracts mature between July 2020 and August 2027. The notional amount and fair value of our interest rate swap contracts recognized as net derivative liabilities as of December 31, 2018 are as follows:

 
  December 31, 2018  
(U.S. Dollars in thousands)
  Notional Amount   Fair Value (asset)  

Interest rate swap contracts

  $ 555,541   $ 15,943  

        As of December 31, 2018, our net exposure to floating interest rate fluctuations on our outstanding debt was approximately $490.1 million, based on our total interest-bearing debt of approximately $1,087.3 million, less the notional amount of our floating to fixed interest rate swap contracts of approximately $555.5 million, less cash and cash equivalents of $41.7 million. A 1% change in short-term interest rates would result in an increase or decrease to our interest expense of approximately $4.9 million on an annual basis as of December 31, 2018. Please read Note 10—Derivative Instruments—Interest Rate Risk Management in the consolidated financial statements included in this Annual Report.

        We and our subsidiaries have the U.S. Dollar as our functional and reporting currency, because all of our revenues and the majority of our expenditures, including the majority of our investments in vessels and our financing transactions, are denominated in U.S. Dollars. We could, however, earn revenue in other currencies, and we currently incur a portion of our expenses in other currencies. Therefore, there is a risk that currency fluctuations could have an adverse effect on the value of our cash flows.

        Our foreign currency risk arises from:

        As of December 31, 2018, we had entered into foreign exchange forward contracts, selling a total notional amount of $30.0 million against NOK at an average exchange rate of NOK 8.14 per 1 U.S. Dollar, which are economic hedges for certain vessel operating expenses and general expenses in NOK. We did not apply hedge accounting to our foreign exchange forward contracts.

        The market for our services is the offshore oil transportation industry, and our customers consist primarily of major oil and gas companies, independent oil and gas producers and government-owned oil companies. As of December 31, 2018 and 2017, seven customers accounted for substantially all of our revenues. Ongoing credit evaluations of our customers are performed and generally do not require collateral in our business agreements. Typically, under our time charters and bareboat charters, the customer pays for the month's charter the first day of each month, which reduces our level of credit risk. Provisions for potential credit losses are maintained when necessary.

        We have bank deposits that expose us to credit risk arising from possible default by the counterparty. We manage the risk by using credit-worthy financial institutions.

Item 15.    Controls and Procedures

Disclosure Controls and Procedures

        We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the U.S. Securities and Exchange Act of 1934, as amended (the "Exchange Act")) that are designed to ensure that (i) information required to be disclosed in our reports that are filed or submitted under the Exchange Act, are recorded, processed, summarized, and reported within the time periods specified in the U.S. Securities and Exchange Commission's rules and forms, and (ii) information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

        We conducted an evaluation of our disclosure controls and procedures under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer. Based on the evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of December 31, 2018.

        The Chief Executive Officer and Chief Financial Officer does not expect that our disclosure controls or internal controls will prevent all errors and all fraud. Although our disclosure controls and procedures were designed to provide reasonable assurance of achieving their objectives, a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Partnership have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Management's Annual Report on Internal Control over Financial Reporting

        Our management is responsible for establishing and maintaining for us adequate internal controls over financial reporting.

        Our internal controls were designed to provide reasonable assurance as to the reliability of our financial reporting and the preparation and presentation of the consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States. Our internal controls over financial reporting include those policies and procedures that: 1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; 2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the financial statements in accordance with generally accepted accounting

129


Table of Contents

principles, and that our receipts and expenditures are being made in accordance with authorizations of management and the directors; and 3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

        We conducted an evaluation of the effectiveness of our internal control over financial reporting based upon the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation.

        Because of its inherent limitations, internal controls over financial reporting may not prevent or detect misstatements even when determined to be effective and can only provide reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate. However, based on the evaluation, management has concluded that our internal controls over financial reporting were effective as of December 31, 2018.

        There were no changes in our internal controls that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the year ended December 31, 2018.

Attestation Report of the Registered Public Accounting Firm

        The effectiveness of the Partnership's internal control over financial reporting as of December 31, 2018 has been audited by Ernst & Young AS, an independent registered public accouting firm, as stated in its report which appears on page F-3 of our consolidated financial statements.

Changes in Internal Control over Financial Reporting

        There were no changes in our internal control over financial reporting that occurred during the period covered by this Annual Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 16G.    Corporate Governance

Overview

        Pursuant to an exemption under the NYSE listing standards for foreign private issuers, the Partnership is not required to comply with the corporate governance practices followed by U.S. companies under the NYSE listing standards. However, pursuant to Section 303A.11 of the NYSE Listed Company Manual, we are required to state any significant differences between our governance practices and the practices required by the NYSE for U.S. companies. We believe that our established

131


Table of Contents

practices in the area of corporate governance are in line with the spirit of the NYSE standards and provide adequate protection to our unitholders. The significant differences between our corporate governance practices and the NYSE standards applicable to listed U.S. companies are set forth below.

Independence of Directors

        The NYSE rules do not require a listed company that is a foreign private issuer to have a board of directors that is comprised of a majority of independent directors. Under Marshall Islands law, we are not required to have a board of directors comprised of a majority of directors meeting the independence standards described in the NYSE rules. In addition, the NYSE rules do not require limited partnerships like us to have boards of directors comprised of a majority of independent directors. However, our board of directors has determined that each of Hans Petter Aas, Edward A. Waryas, Jr., Simon Bird and Andrew Beveridge satisfies the independence standards established by the NYSE as applicable to us.

Executive Sessions

        The NYSE requires that non-management directors of a listed U.S. company meet regularly in executive sessions without management. The NYSE also requires that all independent directors of a listed U.S. company meet in an executive session at least once a year. As permitted under Marshall Islands law and our partnership agreement, our non-management directors do not regularly hold executive sessions without management and we do not expect them to do so in the future.

Nominating/Corporate Governance Committee

        The NYSE requires that a listed U.S. company have a nominating/corporate governance committee of independent directors and a committee charter specifying the purpose, duties and evaluation procedures of the committee. As permitted under Marshall Islands law and our partnership agreement, we do not currently have a nominating or corporate governance committee.

Compensation Committee

        The NYSE requires that a listed U.S. company have a compensation committee of independent directors and a committee charter specifying the purpose, duties and evaluation procedures of the committee. As permitted under Marshall Islands law and our partnership agreement, we do not currently have a compensation committee.

Corporate Governance Guidelines

        The NYSE requires listed U.S. companies to adopt and disclose corporate governance guidelines. The guidelines must address, among other things: director qualification standards, director responsibilities, director access to management and independent advisers, director compensation, director orientation and continuing education, management succession and an annual performance evaluation. We are not required to adopt such guidelines under Marshall Islands law, and we have not adopted such guidelines.

        We make available a statement of significant differences on our website (www.knotoffshorepartners.com).

        We believe that our established corporate governance practices satisfy the NYSE listing standards.

Item 16H.    Mine Safety Disclosure

        Not applicable.

Report of Independent Registered Public Accounting Firm

To the Unitholders and the Board of Directors of KNOT Offshore Partners LP

Opinion on the Financial Statements

        We have audited the accompanying consolidated balance sheets of KNOT Offshore Partners LP (the "Partnership") as of December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive income, partners' capital and cash flows for each of the three years in the period ended December 31, 2018 and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Partnership at December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Partnership's internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated April 10, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

        These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on the Partnership's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

        We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Partnership's auditor since 2013.

        The Partnership's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Controls over Financial Reporting. Our responsibility is to express an opinion on the Partnership's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

        We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

        Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements

1) Description of Business

        KNOT Offshore Partners LP (the "Partnership") was formed as a limited partnership under the laws of the Republic of the Marshall Islands. The Partnership was formed for the purpose of acquiring 100% ownership interests in four shuttle tankers owned by Knutsen NYK Offshore Tankers AS ("KNOT") in connection with the Partnership's initial public offering of its common units (the "IPO"), which was completed on April 15, 2013.

        Pursuant to the Partnership's Amended and Restated Agreement of Limited Partnership (the "Partnership Agreement"), KNOT Offshore Partners GP LLC, a wholly owned subsidiary of KNOT, and the general partner of the Partnership (the "General Partner"), has irrevocably delegated to the Partnership's board of directors the power to oversee and direct the operations of, manage and determine the strategies and policies of the Partnership. During the period from the Partnership's IPO until the time of the Partnership's first annual general meeting ("AGM") on June 25, 2013, the General Partner retained the sole power to appoint, remove and replace all members of the Partnership's board of directors. From the first AGM, four of the seven board members became electable by the common unitholders and accordingly, from this date, KNOT, as the owner of the General Partner, no longer retained the power to control the Partnership's board of directors and, hence, the Partnership. As a result, the Partnership is no longer considered to be under common control with KNOT and as a consequence, the Partnership accounts for acquisitions of businesses and assets under the purchase method of accounting and not as transfers of equity interests between entities under common control. All acquisitions have been consolidated into the Partnership's results as of the date of acquisition. Please read Note 2—Summary of Significant Accounting Policies and Note 21—Acquisitions.

        As of December 31, 2018, the Partnership had a fleet of sixteen shuttle tankers, the Windsor Knutsen, the Bodil Knutsen, the Recife Knutsen, the Fortaleza Knutsen, the Carmen Knutsen, the Hilda Knutsen, the Torill Knutsen, the Dan Cisne, the Dan Sabia, the Ingrid Knutsen, the Raquel Knutsen, the Tordis Knutsen, the Vigdis Knutsen, the Lena Knutsen, the Brasil Knutsen and the Anna Knutsen, each referred to as a "Vessel" and, collectively, as the "Vessels". The Vessels operate under fixed long-term charter contracts to charterers, with expiration dates between 2019 and 2025. Please see Note 6—Operating Leases.

        The consolidated financial statements have been prepared assuming that the Partnership will continue as a going concern.

        On March 1, 2018, the Partnership's wholly owned subsidiary, KNOT Shuttle Tankers AS, acquired KNOT Shuttle Tankers 30 AS, the company that owns the Anna Knutsen, from KNOT. The acquisition of the Anna Knutsen was accounted for as an acquisition of an asset. As a result, the Partnership has recorded the results of operations of the Anna Knutsen in its consolidated statement of operations from March 1, 2018. See Note 21—Acquisitions.

        The Partnership expects that its primary future sources of funds will be available cash, cash from operations, borrowings under any new loan agreements and the proceeds of any equity financings. The Partnership believes that these sources of funds (assuming the current rates earned from existing charters) will be sufficient to cover operational cash outflows and ongoing obligations under the Partnership's financing commitments to pay loan interest and make scheduled loan repayments and to make distributions on its outstanding units. Accordingly, as of April 10, 2019, the Partnership believes that its current resources, including the undrawn portion of its revolving credit facilities of $28.7 million, are sufficient to meet working capital requirements for its current business for at least the next twelve months.

Notes to Consolidated Financial Statements (Continued)

2) Summary of Significant Accounting Policies

(a)
Basis of Preparation

        The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). All intercompany balances and transactions are eliminated.

        The consolidated financial statements include the financial statements of the entities listed in Note 4—Subsidiaries.

(b)
Business Combinations and Asset Acquisitions

        Business combinations are accounted for under the purchase method of accounting. On acquisition, the identifiable assets, liabilities and contingent liabilities are measured at their fair values at the date of acquisition. Any excess of the cost of acquisition over the fair values of the identifiable net assets acquired is recognized as goodwill. The consideration transferred for an acquisition is measured at fair value of the consideration given. Acquisition related costs are expensed as incurred. The results of operations of the acquired businesses are included in the consolidated results as of the date of the applicable acquisition.

        Dependent on the facts and circumstances, the assessment of a transaction may be considered the acquisition of an asset, when substantially all of the fair value of assets acquired is concentrated in a single identifiable asset, rather than a business combination. Asset acquisitions are accounted for by allocating the cost of the acquisition to the individual assets acquired and liabilities assumed on a relative fair value basis. Acquisition related costs are capitalized as a component of the assets acquired.

(c)
Reporting Currency

        The consolidated financial statements are prepared in the reporting currency of U.S. Dollars. The functional currency of the vessel-owning Partnership subsidiaries is the U.S. Dollar, because the subsidiaries operate in the international shipping market, in which all revenues are U.S. Dollar-denominated and the majority of expenditures are made in U.S. Dollars. Transactions involving other currencies during the year are converted into U.S. Dollars using the exchange rates in effect at the time of the transactions. As of the balance sheet dates, monetary assets and liabilities that are denominated in currencies other than the U.S. Dollar are translated to reflect the year-end exchange rates. Resulting gains or losses are reflected separately in the accompanying consolidated statements of operations.

(d)
Use of Estimates

        The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives and impairment of Vessels, drydocking, purchase price allocation and income taxes.

(e)
Revenues and Operating Expenses

        The Partnership recognizes revenues from time charters and bareboat charters as operating leases on a straight-line basis over the term of the charter, net of any commissions. Under time charters, revenue is not recognized during days the Vessel is off-hire. Revenue is recognized from delivery of the Vessel to the charterer, until the end of the contract period. Under time charters, the Partnership is

Notes to Consolidated Financial Statements (Continued)

2) Summary of Significant Accounting Policies (Continued)

responsible for providing the crewing and other services related to the Vessel's operations, the cost of which is included in the daily hire rate, except when off-hire. Under bareboat charters, the Partnership provides a specified Vessel for a fixed period of time at a specified day rate. Where the term of the contract is based on the duration of a single voyage, the partnership evaluates whether the voyage contain leases and if so recognize lease revenue as described above, and when not, recognizes revenue ASC 606 over time on a load-to-discharge basis.

        Voyage expenses are all expenses unique to a particular voyage, including bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls and agency fees. Voyage expenses are paid by the customer under time charter and bareboat charters. Voyage expenses are paid by the Partnership for spot contracts and during periods of off-hire and are recognized when incurred.

        Vessel operating expenses include crewing, repairs and maintenance, insurance, stores, lube oils and communication expenses. Vessel operating expenses are paid by the Partnership for time charters, spot contracts and during off-hire and are recognized when incurred.

        As further discussed in Note 18—Related Party Transactions, related parties have provided the management services for the Vessels and employ the crews that work on the Vessels. The Partnership has no direct employees and, accordingly, is not liable for any pension or post-retirement benefits.

(f)
Financial Income (Expense)

        Other finance expense includes external bank fees, commitment fees paid on undrawn revolving credit facility, financing service fees paid to related parties and guarantee commissions paid to external and related parties in connection with the Partnership's debt and other bank services.

(g)
Cash and Cash Equivalents

        The Partnership considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

(h)
Restricted Cash

        Restricted cash consists of bank deposits, which may only be used to settle principal payments under the Partnership's Vessel financing arrangements.

(i)
Trade Accounts Receivable

        Accounts receivable are recorded at the invoiced amount and do not bear interest. Under terms of the current time charters and bareboat charters, the customers are committed to pay for the full month's charter the first day of each month. See Note 2(s)—Prepaid Charter. The allowance for doubtful accounts is the Partnership's best estimate of the amount of probable credit losses in existing accounts receivable. The Partnership establishes provisions for doubtful accounts on a case-by-case basis when it is unlikely that required payments of specific amounts will occur. In establishing these provisions, the Partnership considers the financial condition of the customer as well as specific circumstances related to the receivable. Receivable amounts determined to be unrecoverable are written-off. There were no allowances for doubtful accounts or amounts written off against the allowance for doubtful accounts as of December 31, 2018 and 2017. The Partnership does not have any off-balance-sheet credit exposure related to its customers.

(j)
Inventories

        Inventories, which are comprised principally of lubricating oils, are stated at the lower of cost or net realizable value. For vessels on time charters or bareboat charters, there are no bunkers, as the charterer supplies the bunkers, which principally consist of fuel oil. Cost is determined using the first-in, first-out method for all inventories.

(k)
Other Current Assets

        Other current assets principally consist of prepaid expenses and other receivables.

(l)
Vessels and Equipment

        Vessels and equipment are stated at the historical acquisition or construction cost, including capitalized interest, supervision and technical and delivery cost, net of accumulated depreciation and impairment loss, if any. Expenditures for subsequent conversions and major improvements are capitalized, provided that such costs increase the earnings capacity or improve the efficiency or safety of the vessels.

        Generally, the Partnership drydocks each vessel every 60 months until the vessel is 15 years old and every 30 months thereafter, as required for the renewal of certifications issued by classification societies. For vessels operating on time charters, the Partnership capitalizes the costs directly associated with the classification and regulatory requirements for inspection of the vessels and improvements incurred during drydocking. Drydock cost is depreciated on a straight-line basis over the period until the next planned drydocking takes place. The Partnership expenses costs related to routine repairs and maintenance performed during drydocking or as otherwise incurred. For vessels that are newly built or acquired, an element of the cost of the vessel is initially allocated to a drydock component and depreciated on a straight-line basis over the period until the next planned drydocking. When significant drydocking expenditures occur prior to the expiration of this period, the Partnership expenses the remaining balance of the original drydocking cost in the month of the subsequent drydocking. For vessels operating on bareboat charters, the charterparty bears the cost of any drydocking.

        Depreciation on vessels and equipment is calculated on a straight-line basis over the asset's estimated useful life, less an estimated residual value, as follows:

 
  Useful Life

Hull

  25 years

Anchor-handling, loading and unloading equipment

  25 years

Main/auxiliary engine

  25 years

Thruster, dynamic positioning systems, cranes and other equipment

  25 years

Drydock costs

  2.5 - 5 years

        A Vessel is depreciated to its estimated residual value, which is calculated based on the weight of the ship and estimated steel price. Any cost related to the disposal is deducted from the residual value.

(m)
Capitalized Interest

        Interest expense incurred on the Partnership's debt during the construction of the Vessels exceeding one year is capitalized during the construction period.

(n)
Impairment of Long-Lived Assets

        Vessels and equipment, vessels under construction and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Partnership first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

(o)
Goodwill and Intangibles

        The Partnership allocates the cost of acquired companies to the identifiable tangible and intangible assets and liabilities acquired, with the remaining amount being classified as goodwill. Goodwill is not amortized but is reviewed for impairment annually or more frequently if impairment indicators are identified.

        The Partnership tests goodwill for impairment using a two-step analysis, with the option of performing a qualitative assessment before performing the first step of the two-step analysis, whereby the carrying value of the reporting unit is compared to its fair value in the first step. If the carrying value of the reporting unit is greater than its fair value, the second step is performed, where the implied fair value of goodwill is compared to its carrying value. An impairment charge is recognized for the amount by which the carrying amount of goodwill exceeds its fair value. The fair value is estimated using the net present value of discounted cash flows of the reporting unit. The Partnership has only one reporting unit.

        Intangible assets represent contractual rights for charters obtained in connection with business and asset acquisitions that have favorable contractual terms relative to market as of the acquisition dates. Contract liabilities represent contractual rights obtained in connection with business acquisitions that have unfavorable contractual terms relative to market as of the acquisition dates. The favorable and unfavorable contract rights have definite lives and are amortized to revenues over the period of the related contracts. Intangible assets with a definite life are tested for impairment whenever events or circumstances indicate that their carrying amount may not be recoverable. An impairment loss is recognized if the carrying amount exceeds the estimated fair value of the asset.

        The contract related intangible assets and liabilities and their amortization periods at acquisition dates are as follows:

Intangible category
  Amortization
Period

Above market time charter—Tordis Knutsen

  4.8 years

Above market time charter—Vigdis Knutsen

  4.9 years

Unfavorable contractual rights—Fortaleza Knutsen

  12 years

Unfavorable contractual rights—Recife Knutsen

  12 years

        The intangible for the above market value of the time charter contract associated with the Tordis Knutsen is amortized to time charter revenue on a straight line basis over the remaining term of the

contract of approximately 4.8 years as of the acquisition date. The intangible for the above market value of the time charter contract associated with the Vigdis Knutsen is amortized to time charter revenue on a straight line basis over the remaining term of the contract of approximately 4.9 years as of the acquisition date.

        The unfavorable contractual rights for charters associated with Foraleza Knutsen and Recife Knutsen were obtained in connection with a step acquisition in 2008 that had unfavorable contractual terms relative to market as of acquisition date. The Fortaleza Knutsen and the Recife Knutsen commenced on their 12 years' fixed bareboat charters in March 2011 and August 2011, respectively. The unfavorable contract rights related to Fortaleza Knutsen and Recife Knutsen are amortized to bareboat revenues on a straight line basis over the 12 years' contract period that expires in March 2023 and August 2023, respectively.

(p)
Debt Issuance Costs

        Debt issuance costs, including fees, commissions and legal expenses, are deferred and presented net of debt. Debt issuance costs of term loans are amortized over the term of the relevant loan. Amortization of debt issuance costs is included in interest expense. These costs are presented as a deduction from the corresponding liability, consistent with debt discount.

(q)
Derivative Instruments

        The Partnership uses derivatives to reduce market risks associated with its operations. The Partnership uses interest rate swaps for the management of interest risk exposure. The interest rate swaps effectively convert a portion of the Partnership's debt from a floating to a fixed rate over the life of the transactions without an exchange of underlying principal.

        The Partnership seeks to reduce its exposure to fluctuations in foreign exchange rates through the use of foreign currency forward contracts.

        All derivative instruments are initially recorded at fair value as either assets or liabilities in the accompanying consolidated balance sheets and subsequently measured to fair value. The Partnership does not apply hedge accounting to its derivative instruments. Changes in the fair value of the derivative instruments are recognized in earnings. Gains and losses from the interest rate swap contracts of the Partnership related to long-term mortgage debt and foreign exchange forward contracts are recorded in realized and unrealized gain (loss) on derivative instruments in the consolidated statements of operations. Cash flows related to interest rate swap contracts are presented as cash flows provided by operating activities. Cash flows related to foreign exchange forward contracts entered into to economically hedge operating expenses in currencies other than U.S. Dollars are presented as cash flows provided by operating activities in the consolidated statements of cash flows, while cash flows related to foreign exchange forward contracts entered into to hedge contractual obligations to pay the shipyard in currencies other than functional currency of U.S. Dollars are presented as cash flows used in investing activities in the consolidated statements of cash flows.

(r)
Income Taxes

        Historically, part of the Partnership's activities were subject to ordinary taxation and taxes were paid on taxable income (including operating income and net financial income and expense), while part of the activities were subject to the Norwegian Tonnage Tax Regime (the "tonnage tax regime"). Under the tonnage tax regime, the tax is based on the tonnage of the vessel, and operating income is tax free.

F-14

KNOT OFFSHORE PARTNERS LP

Notes to Consolidated Financial Statements (Continued)

2) Summary of Significant Accounting Policies (Continued)

The net financial income and expense remains taxable as ordinary income tax for entities subject to the tonnage tax regime. Income taxes arising from the part of activities subject to ordinary taxation are included in income tax expense in the consolidated statements of operations. For the portion of activities subject to the tonnage tax regime, tonnage taxes are classified as vessel operating expenses while the current and deferred taxes arising on net financial income and expense are reflected as income tax expense in the consolidated statements of operations. The amounts of tonnage tax included in operating expenses for the years ended December 31, 2018, 2017 and 2016 were $0.3 million, $0.2 million and $0.2 million, respectively.

        The Partnership accounts for deferred income taxes using the liability method. Under the liability method, deferred tax assets and liabilities are recognized for the anticipated future tax effects of temporary differences between the financial statement basis and the tax basis of the Partnership's assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. A valuation allowance for deferred tax assets is recorded when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized.

        Recognition of uncertain tax positions is dependent upon whether it is more-likely-than-not that a tax position taken or expected to be taken in a tax return will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. If a tax position meets the more-likely-than-not recognition threshold, it is measured to determine the amount of benefit to recognize in the financial statements based on U.S. GAAP guidance. The Partnership recognizes interest and penalties related to uncertain tax positions in income tax expense.

(s)
Prepaid Charter

        Under terms of the time charters and bareboat charters, the customer pays for the month's charter the first day of each month that is recorded as prepaid charter revenues.

(t)
Commitments, Contingencies and Insurance Proceeds

        Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. See Note 19—Commitments and Contingencies.

        Insurance claims for property damage for recoveries up to the amount of loss recognized are recorded when the claims submitted to insurance carriers are probable of recovery. Claims for property damage in excess of the loss recognized and for loss of hire are considered gain contingencies, which are generally recognized when the proceeds are received.

(u)
Fair Value Measurements

        The Partnership utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Partnership determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value

measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

Recently Adopted Accounting Standards

        In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606), as subsequently updated by the FASB, which provides new authoritative guidance on the methods of revenue recognition and related disclosure requirements. This new standard supersedes existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. This update creates a five-step model and requires a company to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligation in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue as each performance obligation is satisfied. Under the new standard, additional qualitative and quantitative disclosures are required. Effective January 1, 2018, the Partnership adopted the requirements of ASC 606 to new and existing contracts not yet completed as of January 1, 2018, using the modified retrospective approach where the cumulative effect of initially applying the standard is recorded as an adjustment to the opening balance of equity. The Partnership made an assessment on the various implementation aspects of ASU 2014-09 and its amendments, and since there are no changes to the timing or amount of revenue recognized, the Partnership has concluded that the effect of the implementation of this new standard will cause no material cumulative effect to the Partnership's historical or future financial position, results of operations or cash flows.

        In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Partnership adopted this ASU prospectively from January 1, 2018. As a result, this increases the likelihood that future dropdowns of Vessels may be considered the acquisition of an asset rather than a business combination.

        On March 1, 2018, the partnership's wholly owned subsidiary, KNOT Shuttle tankers AS, acquired KNOT's 100% interest in KNOT Shuttle Tankers 30 AS ("KNOT 30"), the company that owns and operates the Anna Knutsen. Following the adoption of ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, the Partnership accounted for this acquisition as an acquisition of an asset. The cost of the group of assets acquired in the asset acquisition has been allocated to the individual assets acquired or liabilities assumed based on their relative fair values. See the Note 21—Acquisitions.

2) Summary of Significant Accounting Policies (Continued)

        In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The new guidance clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The Partnership adopted this ASU on January 1, 2018. The Partnership's adoption of this standard did not have a material impact on the Partnership's consolidated statement of cash flows or related disclosures.

        In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash, which requires that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts presented on the statement of cash flows. The standard eliminates the presentation of transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. Additional disclosures are required for the nature of the restricted cash and restricted cash equivalents. The Partnership adopted this ASU on January 1, 2018 under a retrospective approach. The Partnership's adoption of this standard did not have a material impact on the Partnership's consolidated statement of cash flows or related disclosures.

        There are no other recent accounting pronouncements, whose adoption had a material impact on the consolidated financial statements in the current year.

(w)
New Accounting Standards Not Yet Adopted

        In February 2016, the FASB issued ASU 2016-02, Leases (ASC 842). The objective is to establish the principles that lessors and lessees shall apply to report useful information to users of financial statements about the amount, timing and uncertainty of cash flows arising from a lease. The Partnership is the lessor for its Vessels that operate on time charters and bareboat charters. Accounting by a lessor is largely unchanged from the previous standard. The Partnership does not have any material leased assets. A lessee will be required to recognize in its balance sheet a lease liability to make lease payments and a right-of-use asset. The standard requires a modified retrospective transition method for all entities and the standard provides for optional practical expedients in implementing the standard under the modified retrospective approach.

        In July 2018, the FASB issued targeted improvements to the leasing guidance allowing for an additional optional transition method that allow entities to initially apply the new lease standard and its disclosures at the transition date and recognize a cumulative-effect adjustment to the opening balance of retained earnings. The Partnership has elected to use this optional transition approach. The standard is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. The Partnership will adopt ASC 842 and implement the revised guidance as of January 1, 2019. The Partnership will apply the package of practical expedients, but not the hindsight practical expedients since the use of hindsight practical expedient only impacts lease classification if the package of practical expedients is not elected. The Partnership will not reassess whether any expired or existing contracts are, or contain leases, will not reassess lease classification, and will not reassess initial direct costs for any existing leases. Additionally, the practical expedient of disregarding short-term leases for agreements with lease terms of 12 months or less as a lessee and the expedient of not separating lease components from non-lease components will be used for all classes of underlying assets in the Partnership. Based upon assessments performed to date, the Partnership does not expect material effects on the accounting for existing leases applied in the consolidated financial statements where the Partnership is the lessor. Under ASU 2016-02, the Partnership will recognize a right-of-use asset and a lease liability on the balance sheet for certain leases where the Partnership is the lessee

based on the present value of future minimum lease payments, whereas currently no right-of-use asset or lease liability is recognized. Based on the analysis performed by the Partnership to date, the right of use asset and lease liability to be recognized on January 1, 2019 is expected not to be material.

5) Significant Risks and Uncertainties Including Business and Credit Concentrations

        Each of the Vessels is employed under long-term fixed rate charters, which mitigates earnings risk. The Partnership's operational results are dependent on the worldwide market for shuttle tankers and timing of entrance into long-term charters. Market conditions for shipping activities are typically volatile, and, as a consequence, the hire rates may vary from year to year. The market is mainly dependent upon two factors: the supply of vessels and the overall growth in the world economy. The general supply of vessels is impacted by the combination of newbuilds, demolition activity of older vessels and legislation that limits the use of older vessels or new standards for vessels used in specific trades.

        As of December 31, 2018, all of the Partnership's Vessel crews, which are employed through KOAS were represented by collective bargaining agreements that are renegotiated annually, or bi-annually.

        The Partnership did not incur any loss relating to its customers during the years ended December 31, 2018, 2017 and 2016.

        The following table presents time charter and bareboat revenues and percentage of revenues for customers that accounted for more than 10% of the Partnership's revenues during the years ended December 31, 2018, 2017 and 2016. All of these customers are subsidiaries of major international oil companies.

        The Partnership has financial assets that expose it to credit risk arising from possible default by a counterparty. The Partnership considers its counterparties to be creditworthy banking and financial institutions and does not expect any significant loss to result from non-performance by such counterparties. The maximum loss due to credit risk that the Partnership would incur if counterparties failed completely to perform would be the carrying value of cash and cash equivalents, and derivative assets. The Partnership, in the normal course of business, does not demand collateral from its counterparties.

6) Operating Leases

        The time charters and bareboat charters of the Vessels with third parties are accounted for as operating leases. The minimum contractual future revenues to be received from time charters and bareboat charters as of December 31, 2018, were as follows:

7) Segment Information

        The Partnership has not presented segment information as it considers its operations to occur in one reportable segment, the shuttle tanker market. At December 31, 2018, the Partnership's fleet operated under twelve time charters and four bareboat charters. At December 31, 2017, the Partnership's fleet operated under eleven time charters and four bareboat charters and at December 31, 2016, the Partnership's fleet operated under seven time charters and four bareboat charters. See Note 5—Significant Risks and Uncertainties Including Business and Credit Concentrations for revenues from customers accounting for over 10% of the Partnership's consolidated revenue. In both time charters and bareboat charters, the charterer, not the Partnership, controls the choice of which trading areas the Vessels will serve. Accordingly, the Partnership's management, including the chief operating decision makers, does not evaluate performance according to geographical region.

8) Insurance Proceeds

Raquel Knutsen

        In February 2017, the Raquel Knutsen damaged its propeller hub. As a result, the Vessel was off-hire from February 22, 2017 to May 15, 2017 for repairs. Under the Partnership's loss of hire policies, its insurer will pay the Partnership the hire rate agreed in respect of each vessel for each day, in excess of 14 deductible days, for the time that the Vessel is out of service as a result of damage, for a maximum of 180 days. For the year ended December 31, 2017, the Partnership received payments for loss of hire insurance of $3.4 million which was recorded as a component of total revenues since day rates are recovered under terms of the policy.

        In addition, for the year ended December 31, 2017, the Partnership recorded $3.9 million for recoveries up to the amount of loss under hull and machinery insurance for the repairs as a result of the propeller hub damage to the Raquel Knutsen. This is classified under vessel operating expense along

with cost of the repairs of $4.2 million for the period, resulting in a net expense of $0.3 million. See Note 19—Commitments and Contingencies.

Carmen Knutsen

        During the fourth quarter of 2017, the Carmen Knutsen undertook her 5-year special drydocking survey. During dismantling for overhaul, a technical default with her controllable pitch propeller was found. As a result, the Vessel went to a different yard to complete the repair. Repairs were completed and the Vessel was back on hire on January 1, 2018. The additional off-hire and technical costs were subject to an insurance claim. Under its loss of hire insurance policies, the Partnership's insurer is expected to pay the hire rate agreed in respect of the Carmen Knutsen for each day in excess of 14 deductible days while the Vessel was off-hire as a result of the repairs of the controllable pitch propeller. For the years ended December 31, 2018 and 2017, the Partnership recorded $0.45 million and $1.75 million, respectively, for loss of hire which were recorded as a component of total revenues since day rates are recovered under the terms of the policy.

        For the year ended December 31, 2017, the Partnership recorded $2.40 million to vessel operating expense as an estimate of the cost of repairs of the controllable pitch propeller. During 2018, an additional repair cost of $0.15 million was recorded to vessel operating expenses. As of December 31, 2018, the Partnership has received payments and recorded $2.25 million for hull and machinery repairs, resulting in a net expense of $0.30 million. See Note 19—Commitments and Contingencies.

10) Derivative Instruments

Interest Rate Risk Management

        The consolidated financial statements include the results of interest rate swap contracts to manage the Partnership's exposure related to changes in interest rates on its variable rate debt instruments and the results of foreign exchange forward contracts to manage its exposure related to changes in currency exchange rates on its operating expenses, mainly crew expenses, in currency other than the U.S. Dollar and on its contract obligations. The Partnership does not apply hedge accounting for derivative instruments. The Partnership does not speculate using derivative instruments.

        By using derivative financial instruments to economically hedge exposures to changes in interest rates, the Partnership exposes itself to credit risk and market risk. Derivative instruments that economically hedge exposures are used for risk management purposes, but these instruments are not designated as hedges for accounting purposes. Credit risk is the failure of the counterparty to perform under the terms of the derivative instrument. When the fair value of a derivative instrument is positive, the counterparty owes the Partnership, which creates credit risk for the Partnership. When the fair value of a derivative instrument is negative, the Partnership owes the counterparty, and, therefore, the Partnership is not exposed to the counterparty's credit risk in those circumstances. The Partnership minimizes counterparty credit risk in derivative instruments by entering into transactions with major banking and financial institutions. The derivative instruments entered into by the Partnership do not contain credit risk-related contingent features. The Partnership has not entered into master netting agreements with the counterparties to its derivative financial instrument contracts.

        Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates, currency exchange rates or commodity prices. The market risk associated with interest rate contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.

        The Partnership assesses interest rate risk by monitoring changes in interest rate exposures that may adversely impact expected future cash flows and by evaluating economical hedging opportunities.

        The Partnership has historically used variable interest rate mortgage debt to finance its vessels. The variable interest rate mortgage debt obligations expose the Partnership to variability in interest payments due to changes in interest rates. The Partnership believes that it is prudent to limit the variability of a portion of its interest payments. To meet this objective, the Partnership entered into London Interbank Offered Rate ("LIBOR") based interest rate swap contracts to manage fluctuations in cash flows resulting from changes in the benchmark interest rate of LIBOR. These swaps change the variable rate cash flow exposure on the mortgage debt obligations to fixed cash flows. Under the terms of the interest rate swap contracts, the Partnership receives LIBOR-based variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent of fixed rate debt for the notional amount of its debt hedged.

        As of December 31, 2018 and 2017, the total notional amount of the Partnership's outstanding interest rate swap contracts that were entered into in order to hedge outstanding or forecasted debt obligations were $555.5 million and $650.5 million, respectively. As of December 31, 2018 and 2017 the carrying amount of the interest rate swaps contracts were net assets of $15.9 million and $9.7 million, respectively. See Note 11—Fair Value Measurements.

        Changes in the fair value of interest rate swap contracts are reported in realized and unrealized gain (loss) on derivative instruments in the same period in which the related interest affects earnings.

10) Derivative Instruments (Continued)

        The Partnership and its subsidiaries utilize the U.S. Dollar as their functional and reporting currency, because all of their revenues and the majority of their expenditures, including the majority of their investments in vessels and their financing transactions, are denominated in U.S. Dollars. Payment obligations in currencies other than the U.S. Dollar, and in particular operating expenses in NOK, expose the Partnership to variability in currency exchange rates. The Partnership believes that it is prudent to limit the variability of a portion of its currency exchange exposure. To meet this objective, the Partnership entered into foreign exchange forward contracts to manage fluctuations in cash flows resulting from changes in the exchange rates towards the U.S. Dollar. The agreements change the variable exchange rate to fixed exchange rates at agreed dates.

        As of December 31, 2018 and 2017, the total contract amount in foreign currency of the Partnership's outstanding foreign exchange forward contracts that were entered into to economically hedge outstanding future payments in currencies other than the U.S. Dollar were NOK 244.2 million and NOK 249.9 million, respectively. As of December 31, 2018 and 2017, the carrying amount of the Partnership's foreign exchange forward contracts was a net liability of $1.7 million and a net assets of $0.6 million, respectively. See Note 11—Fair Value Measurements.

        The following table presents the realized and unrealized gains and losses that are recognized in earnings as net gain (loss) on derivative instruments for the years ended December 31, 2018, 2017 and 2016:

Carrying amount of long-term debt, current and non-current, above excludes capitalized debt issuance cost of $10.1 million and $6.7 million as of December 31, 2018 and 2017, respectively. The carrying value of trade accounts receivable, trade accounts payable and receivables/payables to owners and affiliates approximate their fair value.

        The fair values of the financial instruments shown in the above table as of December 31, 2018 and 2017 represent the amounts that would be received to sell those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants at that date. Those fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Partnership's own judgment about the assumptions that market participants would use in pricing the asset or liability. Those judgments are developed by the Partnership based on the best information available in the circumstances, including expected cash flows, appropriately risk-adjusted discount rates and available observable and unobservable inputs.

        The following methods and assumptions were used to estimate the fair value of each class of financial instruments:

        As of December 31, 2018, the interest rates on the Partnership's loan agreements were LIBOR plus a fixed margin ranging from 1.8% to 2.4%.

$320 Million Term Loan Facility and $55 Million Revolving Credit Facility

        In September 2018, the Partnership's subsidiaries which own the Windsor Knutsen, the Bodil Knutsen, the Fortaleza Knutsen, the Recife Knutsen, the Carmen Knutsen and the Ingrid Knutsen ("the Vessels"), entered into new senior secured credit facilities (the "Multi-vessels Facility") in order to refinance their existing long term bank debt. The Multi-vessels Facility consists of a term loan of $320 million and a $55 million revolving credit facility. The term loan is repayable in 20 consecutive quarterly installments, with a final payment at maturity in September 2023 of $177 million, which includes the balloon payment and last quarterly installment. The term loan bears interest at a rate per annum equal to LIBOR plus a margin of 2.125%. The revolving credit facility will mature in September 2023, and bears interest at LIBOR plus a margin of 2.125%. There is a commitment fee of 0.85% payable on the undrawn portion of the revolving credit facility. The loans are guaranteed by the Partnership and secured by mortgages on the Vessels. The Multi-vessels Facility refinanced the $220 million facility, the $35 million revolving credit facility, the Fortaleza and Recife loan facility and the Ingrid loan facility.

        The Vessels, assignments of earnings, charterparty contracts and insurance proceeds are pledged as collateral for the Multi-vessel facility. The Partnership and the borrowers (except for the Partnership subsidiary that owns the Recife Knutsen and the Fortaleza Knutsen) are guarantors, and the Multi-vessels Facility is secured by vessel mortgages on the Windsor Knutsen, the Bodil Knutsen, the Fortaleza Knutsen, the Recife Knutsen, the Carmen Knutsen and the Ingrid Knutsen.

        The Multi-vessels Facility contains the following financial covenants:

16) Long-Term Debt (Continued)

        The Multi-vessels Facility also identifies various events that may trigger mandatory reduction, prepayment and cancellation of the facility, including total loss or sale of a vessel and customary events of default. As of December 31, 2018, the borrowers and the guarantors were in compliance with all covenants under this facility.

$220 Million Term Loan Facility and $35 Million Revolving Credit Facility

17) Income Taxes

(a)
Components of Current and Deferred Tax Expense

        All of the income from continuing operations before income taxes was taxable to Norway and UK for the years ended December 31, 2018, 2017 and 2016. The entities and activities taxable to Norway are subject to the Norwegian tonnage tax regime. Under the Norwegian tonnage tax regime, the tax is based on the tonnage of the vessel, and the operating income is tax free. The net financial income and expense remains taxable as ordinary income tax for entities subject to the tonnage tax regime. See Note 2(r)—Income Taxes. The activities taxable to UK relates to KNOT UK and is based on the operating income for the entity.

        The significant components of current and deferred income tax expense attributable to income from continuing operations for the years ended December 31, 2018, 2017 and 2016 are as follows:

        The Partnership records a valuation allowance for deferred tax assets when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. The valuation allowances were $17.0 million and $15.7 million as of December 31, 2018 and 2017, respectively. The valuation allowances relate to the financial loss carry forwards and other deferred tax assets for tonnage tax that, in the judgment of the Partnership, are more-likely-than not to be realized reflecting

the Partnership's cumulative loss position for tonnage tax. In assessing the realizability of deferred tax assets, the Partnership considers whether it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized taking into account all the positive and negative evidence available. As of December 31, 2018, the Partnership determined that the deferred tax assets are likely to not be realized, and the booked value was, therefore, zero. There is no expiration date for losses carried forward.

        After the reorganization of the Partnership's predecessor's activities into the new group structure in February 2013, all profit from continuing operations in Norway is taxable within the tonnage tax regime. The consequence of the reorganization is a one-time entrance tax into the Norwegian tonnage tax regime due to the Partnership's acquisition of the shares in the subsidiary that owns the Fortaleza Knutsen and the Recife Knutsen. The total amount of the entrance tax was estimated to be approximately $3.0 million, which was recognized in the three months ended March 31, 2013. The entrance tax on this gain is payable over several years and is calculated by multiplying the Norwegian tax rate by the declining balance of the gain, which will decline by 20% each year. The Norwegian corporate tax rate was reduced from 24% in 2017 to 23% in 2018 and will be 22% effective as of January 1, 2019. The entrance tax had declined to approximately $2.7 million at December 31, 2013 due to translation effects and tax rate changes and at December 31, 2014 the entrance tax had declined to approximately $1.8 million due to paid entrance tax, change in tax rate and translation effects. At December 31, 2015 the entrance tax had declined to approximately $1.1 million due to paid entrance tax, change in tax rate and translation effects. At December 31, 2016 the entrance tax had declined to approximately $0.9 million due to paid entrance tax, change in tax rate and translation effects. At December 31, 2017 the entrance tax had declined to approximately $0.7 million due to paid entrance tax, change in tax rate and translation effects. At December 31, 2018 the entrance tax had declined to approximately $0.6 million due to paid entrance tax, change in tax rate and translation effects. The taxes payable, mainly related to the entrance tax, are calculated based on a tax rate of 23% for 2018 and 24% for 2017, and the deferred tax liabilities, also mainly related to the entrance tax, are calculated based on a tax rate of 22% and 23% effective as from January 1, 2019 and January 1, 2018, respectively. Income tax expense within the UK of $18,331 and $11,563 for 2018 and 2017, respectively, was calculated by multiplying the tax basis with the UK tax rate of 20%.

        As of December 31, 2018, the total income taxes payable are estimated to be $0.1 million and consist of payable entrance tax and ordinary UK corporation tax. As of December 31, 2017, the total income taxes payable were estimated to be $0.2 million and consist of payable entrance tax and ordinary UK corporation tax.

        As of December 31, 2018, approximately $0.1 million of the estimated entrance tax of $0.6 million is estimated to be payable in the first and second quarter of 2019 and is presented as income taxes payable, while $0.5 million is presented as non-current deferred taxes payable. As of December 31, 2017, approximately $0.2 million of the estimated entrance tax of $0.7 million was estimated to be payable in the first and second quarter of 2018 and was presented as income taxes payable, while $0.5 million was presented as non-current deferred taxes payable. Additionally, a tax liability of approximately $0.1 million was recorded as deferred taxes payable and relates to the acquisition of KNOT Shuttle Tankers 26 AS.

        The tax loss carry forward from ordinary taxation and financial loss carry forwards for tonnage tax have no expiration dates.

17) Income Taxes (Continued)

        The Partnership's Norwegian income tax returns are subject to examination by Norwegian tax authorities going back ten years from 2014. The Partnership had no unrecognized tax benefits as December 31, 2018 and 2017. During the years ended December 31, 2018 and 2017, the Partnership did not incur any interest or penalties on its tax return.

        On December 14, 2017, the Norwegian government concluded the negotiations with the EFTA Surveillance Authority regarding the Norwegian tonnage tax regime, which has been approved for another ten years, until 2027. Pursuant to the approval, Norway has introduced restrictions that eliminates the ability of companies that own vessels under certain bareboat charters to qualify for the Norwegian tonnage tax regime. Companies that no longer qualify for the Norwegian tonnage tax regime will instead be subject to Norwegian corporate income tax. However, there are no limitations on intra-group bareboat chartering, as well as bareboat charters where crewing services are carried out by a related party. In order to constitute a related party, a minimum of 25% ownership/control is required, according to the "associated enterprise" definition in the ATAD directive (Council Directive EU 2016/1164.) Due to the fact that KNOT has an ownership interest in the Partnership that exceeds 25% as well as an ownership interest of 100% in KNOT Management and KNOT Management Denmark AS which provide services to the Vessels owned by the Partnership which operate on bareboat charters, the Vessels operating on bareboat charters are effectively seen as time charter services to the customer. The services are provided to the charterer. If this related party situation is ended, other alternatives and possibly mitigating measures must be evaluated.

18) Related Party Transactions

(a)
Related Parties

        Prior to the IPO, the Partnership's predecessor operated as an integrated part of KNOT. KNOT is owned 50% by TSSI and 50% by Nippon Yusen Kaisha ("NYK").

        The Windsor Knutsen, the Bodil Knutsen, the Carmen Knutsen, the Hilda Knutsen, the Torill Knutsen, the Ingrid Knutsen, the Raquel Knutsen, the Tordis Knutsen, the Vigdis Knutsen, the Lena Knutsen, the Brasil Knutsen and the Anna Knutsen, all of which operate under time charters, are subject to technical management agreements pursuant to which certain crew, technical and commercial management services are provided by KNOT Management or KNOT Management Denmark AS ("KNOT Management Denmark"). Under these technical management agreements, the Partnership's subsidiaries pay fees to and reimburse the costs and expenses of KNOT Management. The Fortaleza Knutsen, the Recife Knutsen, the Dan Cisne and the Dan Sabia operate under bareboat charters and, as a result, the customer is responsible for providing the crew, technical and commercial management of the vessel. However, each of these vessels are subject to management and administration agreements with either KNOT Management or KNOT Management Denmark, a 100% owned subsidiary of KNOT, pursuant to which these companies provide general monitoring services for the vessels in exchange for an annual fee.

        The Partnership is a party to an administrative services agreement with KNOT UK, pursuant to which KNOT UK provides administrative services, and KNOT UK is permitted to subcontract certain of the administrative services provided under the administrative services agreement to KOAS UK and KOAS. On May 7, 2015, the Partnership entered into an amendment to the administrative services agreement, which allows KNOT UK to also subcontract administrative services to KNOT Management. Effective as of February 26, 2018, the Partnership entered into a second amendment to the

Guarantee income from KNOT: Pursuant to the Omnibus Agreement, KNOT agreed to guarantee the payments of the hire rate under the initial charter of the Bodil Knutsen and Windsor Knutsen for a period of five years from the closing date of the IPO (until April 15, 2018). In October 2015, the Windsor Knutsen commenced on a new Shell time charter with a hire rate below the hire rate in the initial charter. The difference between the new hire rate and the initial rate was paid by KNOT until April 15, 2018. The Vigdis Knutsen suffered damages to its hull in connection with a ship-to-ship loading on May 24, 2017 and the vessel went off-hire 6 days in June 2017 due to repairs of the damage. In connection with the Vigdis Knutsen acquisition, KNOT agreed to pay for the repair cost and charter hire lost in connection with the incident. The reimbursement from KNOT for lost charter hire is accounted for as guarantee income. See Note 18(b)—Related Party Transactions—Guarantees and Indemnifications.

Technical and operational management fee from KNOT Management or KNOT Management Denmark to Vessels: KNOT Management or KNOT Management Denmark provides technical and operational management of the vessels on time charter including crewing, purchasing, maintenance and other operational service. In addition, there is also a charge for 24-hour emergency response services provided by KNOT Management for all vessels managed by KNOT Management.

Administration fee from KNOT Management and Knutsen OAS Shipping AS ("KOAS") and Knutsen OAS (UK) Ltd. ("KOAS UK"): Administration costs include the compensation and benefits of KNOT Management's management and administrative staff as well as other general and administration expenses. Some benefits are also provided by KOAS and KOAS UK. Net administration costs are total administration cost plus a 5% margin, reduced for the total fees for services delivered by the administration staffs and the estimated shareholder costs for KNOT that

Administration and management fee from KNOT Management and KNOT Management Denmark: For bareboat charters, the shipowner is not responsible for providing crewing or other operational services and the customer is responsible for all vessel operating expenses and voyage expenses. However, each of the vessels under bareboat charters is subject to a management and administration agreement with either KNOT Management or KNOT Management Denmark, pursuant to which these companies provide general monitoring services for the vessels in exchange for an annual fee.

(5)
Interest expense charged from KNOT: KNOT invoiced interest (expense) income for any outstanding payables to (receivable from) owners and affiliates to the vessel-owning subsidiaries.
(b)
Guarantees and Indemnifications

        Pursuant to the Omnibus Agreement, KNOT agreed to guarantee the payments of the hire rate under the initial charters of each of the Windsor Knutsen and the Bodil Knutsen for a period of five years from the closing date of the IPO (until April 15, 2018).

        In April 2014, the Partnership was notified that Shell would not exercise its option to extend the Windsor Knutsen time charter after the expiration of its initial term. The vessel was re-delivered on July 28, 2014. In order to comply with its obligations under the Omnibus Agreement, on July 29, 2014, KNOT and the Partnership entered into a time charter for the vessel at a rate of hire that would have been in effect during the option period under the previous Shell time charter. This charter was effective until the new Shell time charter commenced in October 2015. The new Shell charter has a hire rate that is lower than the hire rate in the initial charter. The difference between the new hire rate and the initial rate was paid by KNOT until April 15, 2018.

        On June 1, 2017, the Partnership acquired KNOT's 100% interest in KNOT Shuttle Tankers 25 AS, the company that owns and operate the Vigdis Knutsen. Shortly before the closing of the acquisition and on May 24, 2017, the Vigdis Knutsen suffered damages to its hull in connection with a ship-to-ship loading and the vessel went off-hire 6 days in June 2017 due to repairs of the damage. In connection with the Vigdis Knutsen acquisition, KNOT agreed to pay for the repair cost and charter hire lost in connection with the incident.

        Under the Omnibus Agreement, KNOT agreed to indemnify the Partnership until April 15, 2018 (or for a period of at least three years after the purchase of the Hilda Knutsen, the Torill Knutsen, the Ingrid Knutsen and the Raquel Knutsen, as applicable), against certain environmental and toxic tort liabilities with respect to certain assets that KNOT contributed or sold to the Partnership to the extent arising prior to the time they were contributed or sold. However, claims are subject to a deductible of $0.5 million and an aggregate cap of $5 million.

Transactions with Management and Directors

        Trygve Seglem, the Chairman of the Partnership's board of directors and the President and CEO of KNOT, controls Seglem Holding AS, which owns 100% of the equity interest in TSSI, which controls

        The board of directors of the Partnership and the Conflicts Committee of the board approved the purchase price for each transaction described above. The Conflicts Committee retained a financial advisor to assist with its evaluation of each of the transactions. See Note 21—Acquisitions.

19) Commitments and Contingencies

        As of December 31, 2018 and 2017, Vessels with a book value of $1,767 million and $1,723 million, respectively, were pledged as security held as guarantee for the Partnership's long-term debt and interest rate swap obligations. See Note 10—Derivative Instruments, Note 13—Vessels and Equipment and Note 16—Long-Term Debt.

        Under the Partnership's time charters, claims to reduce the hire rate payments can be made if the Vessel does not perform to certain specifications in the agreements. An accrual of $0.4 million for a probable claim was recorded for the year ended December 31, 2017. No accrual for possible claim was recorded for the years ended December 31, 2018 and 2016.

        From time to time, the Partnership is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the consolidated financial position, results of operations or cash flows.

        The Partnership maintains insurance on all the Vessels to insure against marine and war risks, which include damage to or total loss of the Vessels, subject to deductible amounts that average $0.15 million per Vessel, and loss of hire.

19) Commitments and Contingencies (Continued)

        Under the loss of hire policies, the insurer will pay a compensation for the lost hire rate agreed in respect of each Vessel for each day, in excess of 14 deductible days, for the time that the Vessel is out of service as a result of damage, for a maximum of 180 days. In addition, the Partnership maintains protection and indemnity insurance, which covers third-party legal liabilities arising in connection with the Vessels' activities, including, among other things, the injury or death of third-party persons, loss or damage to cargo, claims arising from collisions with other vessels and other damage to other third-party property, including pollution arising from oil or other substances. This insurance is unlimited, except for pollution, which is limited to $1 billion per vessel per incident. The protection and indemnity insurance is maintained through a protection and indemnity association, and as a member of the association, the Partnership may be required to pay amounts above budgeted premiums if the member claims exceed association reserves, subject to certain reinsured amounts. If the Partnership experiences multiple claims each with individual deductibles, losses due to risks that are not insured or claims for insured risks that are not paid, it could have a material adverse effect on the Partnership's results of operations and financial condition.

        In February 2017, the Raquel Knutsen damaged its propeller hub. As a result, the Vessel was off-hire from February 22, 2017 to May 15, 2017 for repairs. Under the Partnership's loss of hire policies, its insurer will pay the Partnership the hire rate agreed in respect of each vessel for each day, in excess of 14 deductible days, for the time that the Vessel is out of service as a result of damage, for a maximum of 180 days. For the year ended December 31, 2017, the Partnership received payments for loss of hire insurance of $3.4 million which was recorded as a component of total revenues since day rates are recovered under terms of the policy.

        In addition, for the year ended December 31, 2017, the Partnership recorded $3.9 million for recoveries up to the amount of loss under hull and machinery insurance for the repairs as a result of the propeller hub damage to the Raquel Knutsen. This is classified under vessel operating expense along with cost of the repairs of $4.2 million for the period, resulting in a net expense of $0.3 million. See Note 8—Insurance Proceeds.

        During the fourth quarter of 2017, the Carmen Knutsen undertook her 5-year special drydocking survey. During dismantling for overhaul, a technical default with her controllable pitch propeller was found. As a result, the Vessel went to a different yard to complete the repair. Repairs were completed and the Vessel was back on hire on January 1, 2018. The additional off-hire and technical costs were subject to an insurance claim. Under its loss of hire insurance policies, the Partnership's insurer is expected to pay the hire rate agreed in respect of the Carmen Knutsen for each day in excess of 14 deductible days while the Vessel was off-hire as a result of the repairs of the controllable pitch propeller. For the years ended December 31, 2018 and 2017, the Partnership recorded $0.45 million and $1.75 million, respectively, for loss of hire which were recorded as a component of total revenues since day rates are recovered under the terms of the policy.

        For the year ended December 31, 2017, the Partnership recorded $2.40 million to vessel operating expense as an estimate of the cost of repairs of the controllable pitch propeller. During 2018, an additional repair cost of $0.15 million was recorded to vessel operating expenses. As of December 31,

20) Earnings per Unit and Cash Distributions (Continued)

(3)
On May 18, 2016, all subordinated units converted into common units on a one-for-one basis.

(4)
Until May 18, 2016, the net income attributable to the IDR holder is included in calculation of earnings per unit for subordinated unitholders, basic and diluted. The IDRs generally were not transferrable by KNOT prior to March 31, 2018. The net income attributable to IDRs for the year ended December 31, 2018, 2017 and 2016 was $2.8 million, $2.6 million and $2.4 million, respectively.

(5)
Refers to cash distributions declared and paid during the period.

(6)
Refers to cash distributions declared and paid subsequent to December 31, 2018.

        As of December 31, 2018, 73.5% of the Partnership's total number of common units outstanding representing limited partner interests were held by the public (in the form of 24,036,226 common units) and 26.2% of such units were held directly by KNOT (in the form of 8,567,500 common units). In addition, KNOT, through its ownership of the General Partner, held a 1.85% general partner interest (in the form of 615,117 general partner units) and a 0.3% limited partner interest (in the form of 90,368 common units).

        Earnings per unit—basic is determined by dividing net income, after deducting the amount of net income attributable to the Series A Preferred Units and the distribution paid or to be made in relation to the period by the weighted-average number of units outstanding during the applicable period.

        The computation of limited partners' interest in net income per common unit—diluted assumes the issuance of common units for all potentially dilutive securities consisting of the Series A Preferred Units. Consequently, the net income attributable to limited partners' interest is exclusive of any distributions on the Series A Preferred Units. In addition, the weigthed average number of common units outstanding has been increased assuming the Series A Preferred Units have been converted to common units using the if-converted method. The computation of limited partners' interest in net income per common unit—diluted does not assume the issuance of Series A Preferred Units if the effect would be anti-dilutive.

        The General Partner's, common unitholders' and subordinated unitholders' interest in net income was calculated as if all net income was distributed according to the terms of the Partnership Agreement, regardless of whether those earnings would or could be distributed. The Partnership Agreement does not provide for the distribution of net income. Rather, it provides for the distribution of available cash, which is a contractually defined term that generally means all cash on hand at the end of each quarter less the amount of cash reserves established by the Partnership's board of directors (the "Board") to provide for the proper conduct of the Partnership's business, including reserves for maintenance and replacement capital expenditures, anticipated credit needs and capital requirements and any accumulated distributions on, or redemptions of, the Series A Preferred Units. In addition, KNOT, as the initial holder of all IDRs, has the right, at the time when there are no subordinated units outstanding and it has received incentive distributions at the highest level to which it is entitled (48.0% for each of the prior four consecutive fiscal quarters), to reset the initial cash target distribution levels at higher levels based on the distribution at the time of the exercise of the reset election. Unlike

available cash, net income is affected by non-cash items, such as depreciation and amortization, unrealized gains and losses on derivative instruments and unrealized foreign currency gains and losses.

        Distributions of available cash from operating surplus for any quarter are required to be made in the following manner:

        The percentage interests set forth above assumed that the General Partner continues to own a 1.85% general partner interest and that the Partnership has not issued additional classes of equity securities.

21) Acquisitions

        During the years ended December 31, 2016 through 2018, the Partnership acquired from KNOT equity interests in certain subsidiaries which own and operate the Raquel Knutsen, the Tordis Knutsen, the Vigdis Knutsen, the Lena Knutsen, the Brasil Knutsen and the Anna Knutsen.

        The board of directors of the Partnership and the Conflicts Committee approved the purchase price for each transaction. The Conflicts Committee retained a financial advisor to assist with its evaluation of the transactions. The cost of the fee paid to the financial advisor was divided equally between the Partnership and KNOT. Acquisition related costs of $0.1 million, $0.2 million and $0.1 million as of December 31, 2018, 2017 and 2016, respectively, were expensed as incurred under general and administrative expenses. The allocation of the purchase price to acquired identifiable assets was based on their estimated fair values at the date of acquisition. The purchase price of each

Vessel and equipment includes allocation to drydocking for the following vessels (in thousands): Anna Knutsen of $2,329, Brasil Knutsen of $260, Lena Knutsen of $2,741, Vigdis Knutsen of $2,709, Tordis Knutsen of $2,753 and Raquel Knutsen of $1,663.

        On March 1, 2018, the Partnership's wholly owned subsidiary, KNOT Shuttle Tankers AS, acquired KNOT's 100% interest in KNOT Shuttle Tankers 30 AS ("KNOT 30"), the company that owns and operates the Anna Knutsen.

The Partnership used $30.0 million of the net proceeds to repay the revolving credit facility, which was drawn in connection with acquisition of the Vigdis Knutsen.

        The Series A Preferred Units rank senior to the common units as to the payment of distributions and amounts payable upon liquidation, dissolution or winding up. The Series A Preferred Units have a liquidation preference of $24.00 per unit, plus any Series A unpaid cash distributions, plus all accrued but unpaid distributions on such Series A Preferred Unit with respect to the quarter in which the liquidation occurs to the date fixed for the payment of any amount upon liquidation. The Series A Preferred Units are entitled to cumulative distributions from their initial issuance date, with distributions being calculated at an annual rate of 8.0% on the stated liquidation preference and payable quarterly in arrears within 45 days after the end of each quarter, when, as and if declared by the Board.

        The Series A Preferred Units are generally convertible, at the option of the holders of the Series A Preferred Units, into common units commencing on February 2, 2019 at the then applicable conversion rate. The conversion rate will be subject to adjustment under certain circumstances. In addition, the conversion rate will be redetermined on a quarterly basis, such that the conversion rate will be equal to $24.00 (the "Issue Price") divided by the product of (x) the book value per common unit at the end of the immediately preceding quarter (pro-forma for per unit cash distributions payable with respect to such quarter) multiplied by (y) the quotient of (i) the Issue Price divided by (ii) the book value per common unit on February 2, 2017. In addition, the Partnership may redeem the Series A Preferred Units at any time between February 2, 2019 and February 2, 2027 at the redemption price specified in the Partnership Agreement, provided, however, that upon notice from the Partnership to the holders of Series A Preferred Units of its intent to redeem, such holders may elect, instead, to convert their Series A Preferred Units into common units at the then applicable conversion rate. For the year ended December 31, 2018, the possible conversion of the Series A Preferred Units into

        Upon a change of control of the Partnership, the holders of Series A Preferred Units will have the right to require cash redemption at 100% of the Issue Price. In addition, the holders of Series A Preferred Units will have the right to cause the Partnership to redeem the Series A Preferred Units on February 2, 2027 in, at the option of the Partnership, (i) cash at a price equal to 70% of the Issue Price or (ii) common units such that each Series A Preferred Unit receives common units worth 80% of the Issue Price (based on the volume-weighted average trading price, as adjusted for splits, combinations and other similar transactions, of the common units as reported on the NYSE for the 30 trading day period ending on the fifth trading day immediately prior to the redemption date) plus any accrued and unpaid distributions. In addition, at any time following February 2, 2019 and subject to certain conditions, the Partnership will have the right to convert the Series A Preferred Units into common units at the then applicable conversion rate if the aggregate market value (calculated as set forth in the partnership agreement) of the common units into which the then outstanding Series A Preferred Units are convertible, based on the then applicable conversion rate, is greater than 130% of the aggregate Issue Price of the then outstanding Series A Preferred Units.

        The Series A Preferred Units have voting rights that are identical to the voting rights of the common units, except they do not have any right to nominate, appoint or elect any of the directors of the Board, except whenever distributions payable on the Series A Preferred Units have not been declared and paid for four consecutive quarters (a "Trigger Event"). Upon a Trigger Event, holders of Series A Preferred Units, together with the holders of any other series of preferred units upon which like rights have been conferred and are exercisable, may replace one of the members of the Board appointed by the General Partner with a person nominated by such holders, such nominee to serve until all accrued and unpaid distributions on the preferred units have been paid. The Series A Preferred Units are entitled to vote with the common units as a single class so that the Series A Preferred Units are entitled to one vote for each common unit into which the Series A Preferred Units are convertible at the time of voting.

        For additional information about the Series A Preferred Units, please read the Partnership's Report on Form 8-A/A filed with the Securities and Exchange Commission on June 30, 2017.

10.                               HOLIDAYS

 

10.1                        The Employee shall be entitled to 30 business days’ paid holiday in each holiday year together with the usual public holidays in England. The Company’s holiday year runs

 

6


 

between 1 January and 31 December. If the Appointment commences or terminates part way through a holiday year, the Employee’s entitlement during that holiday year shall be calculated on a pro-rata basis.

 

10.2                        To the extent reasonably possible, the Employee shall take holiday at such time or times that result in minimal disruption to the business of the Group. The Employee shall not without the written consent of the Board carry forward any accrued but untaken holiday entitlement to a subsequent holiday year.

 

10.3                        The Employee shall have no entitlement to any payment in lieu of accrued but untaken holiday except on termination of the Appointment. Subject to clause 10.4 the amount of such payment in lieu shall be 1/260th of the Employee’s salary for each untaken day of the entitlement under clause 10.1 for the holiday year in which termination takes place and any untaken days carried forward from the preceding holiday year.

 

10.4                        If the Company has terminated or would be entitled to terminate the Appointment under clause 17 or if the Employee has terminated the Appointment in breach of this agreement any payment due under clause 10.3 shall be limited to the Employee’s statutory entitlement under the Working Time Regulations 1998 and any paid holidays (including paid public holidays) taken shall be deemed first to have been taken in satisfaction of that statutory entitlement.

 

10.5                        If on termination of the Appointment the Employee has taken in excess of his accrued holiday entitlement, the Company shall be entitled to recover from the Employee by way of deduction from any payments due to the Employee or otherwise one day’s pay calculated at 1/260th of the Employee’s salary for each excess day.

 

10.6                        If either party has served notice to terminate the Appointment, the Board may require the Employee to take any accrued but unused holiday entitlement during the notice period. Any accrued but unused holiday entitlement shall be deemed to be taken during any period of Garden Leave under clause 18.

 

10.7                        During any continuous period of absence due to Incapacity of one month or more the Employee shall not accrue holiday under this contract and the Employee’s entitlement under clause 10.1 for the holiday year in which such absence takes place shall be reduced pro rata save that it shall not fall below the Employee’s entitlement under the Working Time Regulations 1998.

 

11.                               INCAPACITY

 

11.1                        Subject to the Employee’s compliance with this agreement and the Company’s sickness absence procedures (as amended from time to time), the Employee shall continue to receive his full salary and contractual benefits during any period of

 

7


 

absence due to Incapacity for up to an aggregate of 13 weeks in any 52-week period. Such payment shall be inclusive of any statutory sick pay due in accordance with applicable legislation.

 

11.2                        The Employee agrees to consent to medical examinations (at the Company’s expense) by a doctor nominated by the Company should the Company so require. The Employee agrees that any report produced in connection with any such examination may be disclosed to the Company and the Company may discuss the contents of the report with the relevant doctor.

 

11.3                        If the Incapacity is or appears to be occasioned by actionable negligence, nuisance or breach of any statutory duty on the part of a third party in respect of which damages are or may be recoverable, the Employee shall immediately notify the Board of that fact and of any claim, compromise, settlement or judgment made or awarded in connection with it and all relevant particulars that the Board may reasonably require. The Employee shall if required by the Board, refund to the Company that part of any damages or compensation recovered by him relating to the loss of earnings for the period of the Incapacity as the Board may reasonably determine less any costs borne by him in connection with the recovery of such damages or compensation, provided that the amount to be refunded shall not exceed the total amount paid to the Employee by the Company in respect of the period of Incapacity.

 

11.4                        The rights of the Company to terminate the Appointment under the terms of this Agreement apply even when such termination would or might cause the Employee to forfeit any entitlement to sick pay, permanent health insurance or other benefits.

 

12.                               OUTSIDE INTERESTS

 

12.1                        Subject to clause 12.2, during the Appointment the Employee shall not, except as a representative of the Company or with the prior written approval of the Board, whether paid or unpaid, be directly or indirectly engaged, concerned or have any financial interest in any Capacity in any other business, trade, profession or occupation (or the setting up of any business, trade, profession or occupation).

 

12.2                        Notwithstanding clause 12.1, the Employee may hold an investment by way of shares or other securities of not more than 5% of the total issued share capital of any company (whether or not it is listed or dealt in on a recognised stock exchange) where such company does not carry on a business similar to or competitive with any business for the time being carried on by any Group Undertaking.

 

12.3                        Notwithstanding clauses 4.2(f) and 13.1, the Employee may serve on corporate, industry, civic, religious or charitable boards or committees so long as such activities do not violate the terms of any other clause of this agreement, present a conflict of interest, or interfere in any material respect with the performance of the Employee’s

 

8


 

duties and responsibilities pursuant to this agreement; provided, further that any service by the Employee on a board or committee of a for-profit entity shall be subject to the prior written approval of the Board.

 

13.                               CONFIDENTIAL INFORMATION

 

13.1                        The Employee acknowledges that in the course of the Appointment he will have access to Confidential Information. The Employee has therefore agreed to accept the restrictions in this clause 13.

 

13.2                        The Employee shall not (except in the proper course of his duties), either during the Appointment or at any time after its termination (however arising), use or disclose to any person, company or other organisation whatsoever (and shall use his best endeavours to prevent the publication or disclosure of) any Confidential Information. This shall not apply to:

 

(a)                       any use or disclosure authorised by the Board or required by law;

 

(b)                       any information which is already in, or comes into, the public domain other than through the Employee’s unauthorised disclosure; or

 

(c)                        any protected disclosure within the meaning of section 43A of the Employment Rights Act 1996.

 

14.                               INTELLECTUAL PROPERTY

 

14.1                        The Employee shall give the Company full written details of all Inventions and of all works embodying Intellectual Property Rights made wholly or partially by him at any time during the course of the Appointment. The Employee acknowledges that all Intellectual Property Rights subsisting (or which may in the future subsist) in all such Inventions and works shall automatically, on creation, vest in the Company absolutely. To the extent that they do not vest automatically, the Employee holds them on trust for the Company. The Employee agrees promptly to execute all documents and do all acts as may, in the opinion of the Company, be necessary to give effect to this clause 14.1.

 

14.2                        The Employee hereby irrevocably waives all moral rights under the Copyright, Designs and Patents Act 1988 (and all similar rights in other jurisdictions) which he has or will have in any existing or future works referred to in clause 14.1.

 

14.3                        The Employee irrevocably appoints the Company to be his attorney in his name and on his behalf to execute documents, use the Employee’s name and do all things which are necessary or desirable for the Company to obtain for itself or its nominee the full benefit of this clause.  A certificate in writing, signed by any director or the secretary of the Company, that any instrument or act falls within the authority conferred by this

 

9


 

agreement shall be conclusive evidence that such is the case so far as any third party is concerned.

 

15.                               CEASING TO BE A DIRECTOR

 

15.1                        Except with the prior approval of the Board, or as provided in the articles of association of any Group Undertaking of which he is a director, the Employee shall not resign as a director of any Group Undertaking.

 

15.2                        If during the Appointment the Employee ceases to be a director of any Group Undertaking (otherwise than by reason of his death, resignation or disqualification pursuant to the articles of association of the relevant Group Undertaking, as amended from time to time, or by statute or court order) the Appointment shall continue with the Employee as an employee only and the terms of this agreement (other than those relating to the holding of the office of director) shall continue in full force and effect. The Employee shall have no claims in respect of such cessation of office.

 

16.                               PAYMENT IN LIEU OF NOTICE

 

16.1                        Notwithstanding clause 2, the Company may, in its sole and absolute discretion, terminate the Appointment at any time and with immediate effect by notifying the Employee that the Company is exercising its right under this clause 16.1 and that it will make within 28 days a payment in lieu of notice (Payment in Lieu) to the Employee. This Payment in Lieu will be equal to the basic salary (as at the date of termination) which the Employee would have been entitled to receive under this agreement during the notice period referred to at clause 2 (or, if notice has already been given, during the remainder of the notice period) less income tax and National Insurance contributions. For the avoidance of doubt, the Payment in Lieu shall not include any element in relation to:

 

(a)                       any bonus or commission payments that might otherwise have been due during the period for which the Payment in Lieu is made;

 

(b)                       any payment in respect of benefits which the Employee would have been entitled to receive during the period for which the Payment in Lieu is made; and

 

(c)                        any payment in respect of any holiday entitlement that would have accrued during the period for which the Payment in Lieu is made.

 

16.2                        The Company may pay any sums due under clause 16.1 in equal monthly instalments until the date on which the notice period referred to at clause 2 would have expired if notice had been given.

 

10


 

16.3                        The Employee shall have no right to receive a Payment in Lieu unless the Company has exercised its discretion in clause 16.1. Nothing in this clause 16 shall prevent the Company from terminating the Appointment in breach.

 

16.4                        Notwithstanding clause 16.1 the Employee shall not be entitled to any Payment in Lieu if the Company would otherwise have been entitled to terminate the Appointment without notice in accordance with clause 17. In that case the Company shall also be entitled to recover from the Employee any Payment in Lieu (or instalments thereof) already made.

 

17.                               TERMINATION WITHOUT NOTICE

 

17.1                        The Company may also terminate the Appointment with immediate effect without notice and with no liability to make any further payment to the Employee (other than in respect of amounts accrued due at the date of termination) if the Employee:

 

(a)                       is in breach of the Company’s or any Parent Company’s anti-corruption and bribery policy and related procedures;

 

(b)                       is guilty of any gross misconduct affecting the business of any Group Undertaking;

(e)                        is declared bankrupt or makes any arrangement with or for the benefit of his creditors or has a county court administration order made against him under the County Court Act 1984;

 

(f)                         is convicted of any criminal offence (other than an offence under any road traffic legislation in the United Kingdom or elsewhere for which a fine or non-custodial penalty is imposed);

 

(g)                        becomes of unsound mind (which includes lacking capacity under the Mental Capacity Act 2005), or a patient under any statute relating to mental health;

 

(h)                       ceases to be eligible to work in the United Kingdom;

 

(i)                           is guilty of any fraud or dishonesty or acts in any manner which in the reasonable opinion of the Board brings or is likely to bring the Employee or any Group Undertaking into disrepute or is materially adverse to the interests of any Group Undertaking;

 

(j)                          is guilty of a serious breach of any rules issued by the Company from time to time regarding its electronic communications systems; or

 

11


 

(k)                       is unable by reason of Incapacity to perform his duties under this agreement for an aggregate period of 30 weeks in any 52-week period.

 

17.2                        The rights of the Company under clause 17.1 are without prejudice to any other rights that it might have at law to terminate the Appointment or to accept any breach of this agreement by the Employee as having brought the agreement to an end. Any delay by the Company in exercising its rights to terminate shall not constitute a waiver thereof.

 

18.                               GARDEN LEAVE

 

18.1                        Following service of notice to terminate the Appointment by either party, or if the Employee purports to terminate the Appointment in breach of contract, the Board may by written notice place the Employee on Garden Leave for the whole or part of the remainder of the Appointment.

 

18.2                        During any period of Garden Leave:

 

(a)                       the Company shall be under no obligation to provide any work to the Employee and may revoke any powers the Employee holds on behalf of the Company or any Group Undertaking;

 

(b)                       the Company may require the Employee to carry out alternative duties or to only perform such specific duties as are expressly assigned to the Employee, at such location (including the Employee’s home) as the Company may decide;

 

(c)                        the Employee shall continue to receive his basic salary and all contractual benefits in the usual way and subject to the terms of any benefit arrangement;

 

(d)                       the Employee shall remain an employee of the Company and bound by the terms of this agreement (including any implied duties of good faith and fidelity);

 

(e)                        the Company may exclude the Employee from any premises of the Company or any Group Undertaking; and

 

(f)                         the Company may require the Employee not to contact or deal with (or attempt to contact or deal with) any officer, employee, consultant, client, customer, supplier, agent, distributor, shareholder, adviser or other business contact of the Company or any Group Undertaking.

12


 

(b)                       subject to clause 19.2, immediately deliver to the Company all documents, books, materials, records, correspondence, papers and information (on whatever media and wherever located) relating to the business or affairs of any Group Undertaking or its business contacts, any keys, credit card and any other property of any Group Undertaking, which is in his possession or under his control;

19.2                        Where the Employee has been placed on Garden Leave he shall not be required by clause 19.1 to return until the end of the Garden Leave period any property provided to him as a contractual benefit for use during the Appointment.

 

19.3                        The Employee hereby irrevocably appoints the Company to be his attorney to execute and do any such instrument or thing and generally to use his name for the purpose of giving the Company or its nominee the full benefit of clause 19.1(a).

 

20.                               POST-TERMINATION RESTRICTIONS

 

20.1                        In order to protect the confidential information, trade secrets and business connections of the Company and each Group Undertaking to which he has access as a result of the Appointment, the Employee covenants with the Company (for itself and as trustee and agent for each Group Undertaking) that he shall not for 12 months after Termination:

 

(a)                       solicit or endeavour to entice away from the Company or any Group Undertaking the business or custom of a Restricted Customer with a view to providing goods or services to that Restricted Customer in competition with any Restricted Business;

 

(b)                       in the course of any business concern which is in competition with any Restricted Business, offer to employ or engage or otherwise endeavour to entice away from the Company or any Group Undertaking any Restricted Person;

 

(c)                        in the course of any business concern which is in competition with any Restricted Business, employ or engage or otherwise facilitate the employment or engagement of any Restricted Person, whether or not such person would be in breach of contract as a result of such employment or engagement;

 

13


 

(d)                       be involved in any Capacity with any business concern which is (or intends to be) in competition with any Restricted Business;

 

(e)                        be involved with the provision of goods or services to (or otherwise have any business dealings with) any Restricted Customer in the course of any business concern which is in competition with any Restricted Business, or

 

at any time after Termination, represent himself as connected with the Company or any Group Undertaking in any Capacity, other than as a former employee, or use any registered business names or trading names associated with the Company or any Group Undertaking.

 

20.2                        None of the restrictions in clause 20.1 shall prevent the Employee from:

 

(a)                       holding an investment by way of shares or other securities of not more than 5% of the total issued share capital of any company, whether or not it is listed or dealt in on a recognised stock exchange;

 

(b)                       being engaged or concerned in any business concern insofar as the Employee’s duties or work shall relate solely to geographical areas where the business concern is not in competition with any Restricted Business; or

 

(c)                        being engaged or concerned in any business concern, provided that the Employee’s duties or work shall relate solely to services or activities of a kind with which the Employee was not concerned to a material extent in the 12 months before Termination.

 

20.3                        The restrictions imposed on the Employee by this clause 20 apply to him acting:

 

(a)                       directly or indirectly; and

 

(b)                       on his own behalf or on behalf of, or in conjunction with, any firm, company or person.

 

20.4                        The period for which the restriction in clause 20.1 apply shall be reduced by any period that the Employee spends on Garden Leave immediately before Termination.

 

20.5                        If the Employee receives an offer to be involved in a business concern in any Capacity during the Appointment, or before the expiry of the last of the covenants in this clause 20, the Employee shall give the person making the offer a copy of this clause 20.

 

20.6                        The Company and the Employee entered into the restrictions in this clause 20 having been separately legally advised.

 

20.7                        Each of the restrictions in this clause 20 is intended to be separate and severable. If any of the restrictions shall be held to be void but would be valid if part of their

 

14


 

wording were deleted, such restriction shall apply with such deletion as may be necessary to make it valid or effective.

 

20.8                        If the Employee’s employment is transferred to any firm, company, person or entity other than a Group Undertaking (the “New Employer”) pursuant to the Transfer of Undertakings (Protection of Employment) Regulations 2006, the Employee will, if required, enter into an agreement with the New Employer containing post-termination restrictions corresponding to those restrictions in this clause 20, protecting the confidential information, trade secrets and business connections of the New Employer.

 

20.9                        The Employee will, at the request and expense of the Company, enter into a separate agreement with any Group Undertaking in which he agrees to be bound by restrictions corresponding to those restrictions in this clause 20 (or such of those restrictions as the Company deems appropriate) in relation to that Group Undertaking.

 

21.                               DISCIPLINARY AND GRIEVANCE PROCEDURES

 

21.1                        The Employee is subject to the Company’s disciplinary and grievance procedures. These procedures do not form part of the Employee’s contract of employment.

 

21.2                        If the Employee wants to raise a grievance, he may apply in writing to the Board in accordance with the Company’s grievance procedure.

 

21.3                        If the Employee wishes to appeal against a disciplinary decision he may apply in writing to the Board in accordance with the Company’s disciplinary procedure.

 

21.4                        The Board may suspend the Employee from any or all of his duties for a period of up to 21 days during any period in which the Company is investigating any disciplinary matter involving the Employee or while any disciplinary procedure against the Employee is outstanding.

 

21.5                        During any period of suspension:

 

(a)                       the Employee shall continue to receive his basic salary and all contractual benefits in the usual way and subject to the terms of any benefit arrangement;

 

(b)                       the Employee shall remain an employee of the Company and bound by the terms of this agreement;

 

(c)                        the Board may exclude the Employee from his place of work or any other premises of the Company or any Group Undertaking; and

 

15


 

(d)                       the Board may require the Employee not to contact or deal with (or attempt to contact or deal with) any officer, employee, consultant, client, customer, supplier, agent, distributor, shareholder, adviser or other business contact of the Company or any Group Undertaking.

 

22.                               PENSION

 

Before signing this agreement, the Employee confirmed that, in light of his own existing personal pension arrangements, his intention is to opt out of the Company’s auto enrolment pension scheme (the “Scheme”) and to remain opted out of the Scheme for the duration of the Appointment. The remuneration and benefits package provided to him under the terms of this agreement reflects the Employee’s stated intentions in this regard and the reasons for them.

 

23.                               DATA PROTECTION

 

23.1                        The Employee consents to any Group Undertaking processing data relating to the Employee for legal, personnel, administrative and management purposes and in particular to the processing of any sensitive personal data (as defined in the Data Protection Act 1998) relating to the Employee, including, as appropriate:

 

(a)                       information about the Employee’s physical or mental health or condition in order to monitor sick leave and take decisions as to the Employee’s fitness for work;

 

(b)                       the Employee’s racial or ethnic origin or religious or similar information in order to monitor compliance with equal opportunities legislation; and

 

(c)                        information relating to any criminal proceedings in which the Employee has been involved for insurance purposes and in order to comply with legal requirements and obligations to third parties.

 

23.2                        The Company may make such information available to any Group Undertaking, those who provide products or services to any Group Undertaking (such as advisers and payroll administrators), regulatory authorities, potential or future employers, governmental or quasi-governmental organisations and potential purchasers of the Company or the business in which the Employee works.

 

23.3                        The Employee consents to the transfer of such information to any Group Undertaking and any Group Undertaking’s business contacts outside the European Economic Area in order to further their business interests even where the country or territory in question does not maintain adequate data protection standards.

 

24.                               COLLECTIVE AGREEMENTS

 

There is no collective agreement which directly affects the Appointment.

 

16


 

25.                               RECONSTRUCTION AND AMALGAMATION

 

If the Appointment is terminated at any time by reason of any reconstruction or amalgamation of the Company or any Group Undertaking, whether by winding up or otherwise, and the Employee is offered employment with any concern or undertaking involved in or resulting from the reconstruction or amalgamation on terms which (considered in their entirety) are no less favourable to any material extent than the terms of this agreement, the Employee shall have no claim against the Company or any such undertaking arising out of or connected with the termination.

1) Description of Business

KNOT Offshore Partners LP (the “Partnership”) was formed as a limited partnership under the laws of the Republic of the Marshall Islands. The Partnership was formed for the purpose of acquiring 100% ownership interests in four shuttle tankers owned by Knutsen NYK Offshore Tankers AS (“KNOT”) in connection with the Partnership’s initial public offering of its common units (the “IPO”), which was completed on April 15, 2013.

Pursuant to the Partnership’s Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”), KNOT Offshore Partners GP LLC, a wholly owned subsidiary of KNOT, and the general partner of the Partnership (the “General Partner”), has irrevocably delegated to the Partnership’s board of directors the power to oversee and direct the operations of, manage and determine the strategies and policies of the Partnership. During the period from the Partnership’s IPO until the time of the Partnership’s first annual general meeting (“AGM”) on June 25, 2013, the General Partner retained the sole power to appoint, remove and replace all members of the Partnership’s board of directors. From the first AGM, four of the seven board members became electable by the common unitholders and accordingly, from this date, KNOT, as the owner of the General Partner, no longer retained the power to control the Partnership’s board of directors and, hence, the Partnership. As a result, the Partnership is no longer considered to be under common control with KNOT and as a consequence, the Partnership accounts for acquisitions of businesses and assets under the purchase method of accounting and not as transfers of equity interests between entities under common control. All acquisitions have been consolidated into the Partnership’s results as of the date of acquisition. Please read Note 2—Summary of Significant Accounting Policies and Note 21—Acquisitions.

As of December 31, 2018, the Partnership had a fleet of sixteen shuttle tankers, the Windsor Knutsen , the Bodil Knutsen , the Recife   Knutsen , the Fortaleza Knutsen , the Carmen Knutsen, the Hilda Knutsen, the Torill Knutsen , the Dan Cisne , the Dan Sabia, the Ingrid   Knutsen , the Raquel Knutsen, the Tordis Knutsen, the Vigdis Knutsen, the Lena Knutsen, the Brasil Knutsen and the Anna Knutsen, each referred to as a “Vessel” and, collectively, as the “Vessels”. The Vessels operate under fixed long-term charter contracts to charterers, with expiration dates between 2019 and 2025. Please see Note 6—Operating Leases.

The consolidated financial statements have been prepared assuming that the Partnership will continue as a going concern.

On March 1, 2018, the Partnership’s wholly owned subsidiary, KNOT Shuttle Tankers AS, acquired KNOT Shuttle Tankers 30 AS, the company that owns the Anna Knutsen , from KNOT. The acquisition of the Anna Knutsen was accounted for as an acquisition of an asset. As a result, the Partnership has recorded the results of operations of the Anna Knutsen in its consolidated statement of operations from March 1, 2018. See Note 21—Acquisitions.

The Partnership expects that its primary future sources of funds will be available cash, cash from operations, borrowings under any new loan agreements and the proceeds of any equity financings. The Partnership believes that these sources of funds (assuming the current rates earned from existing charters) will be sufficient to cover operational cash outflows and ongoing obligations under the Partnership’s financing commitments to pay loan interest and make scheduled loan repayments and to make distributions on its outstanding units. Accordingly, as of April 10, 2019, the Partnership believes that its current resources, including the undrawn portion of its revolving credit facilities of $28.7 million, are sufficient to meet working capital requirements for its current business for at least the next twelve months.

Summary of Significant Accounting Policies

2) Summary of Significant Accounting Policies

(a) Basis of Preparation

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany balances and transactions are eliminated.

The consolidated financial statements include the financial statements of the entities listed in Note 4—Subsidiaries.

(b) Business Combinations and Asset Acquisitions

Business combinations are accounted for under the purchase method of accounting. On acquisition, the identifiable assets, liabilities and contingent liabilities are measured at their fair values at the date of acquisition. Any excess of the cost of acquisition over the fair values of the identifiable net assets acquired is recognized as goodwill. The consideration transferred for an acquisition is measured at fair value of the consideration given. Acquisition related costs are expensed as incurred. The results of operations of the acquired businesses are included in the consolidated results as of the date of the applicable acquisition.

Dependent on the facts and circumstances, the assessment of a transaction may be considered the acquisition of an asset, when substantially all of the fair value of assets acquired is concentrated in a single identifiable asset, rather than a business combination. Asset acquisitions are accounted for by allocating the cost of the acquisition to the individual assets acquired and liabilities assumed on a relative fair value basis. Acquisition related costs are capitalized as a component of the assets acquired.

(c) Reporting Currency

The consolidated financial statements are prepared in the reporting currency of U.S. Dollars. The functional currency of the vessel-owning Partnership subsidiaries is the U.S. Dollar, because the subsidiaries operate in the international shipping market, in which all revenues are U.S. Dollar-denominated and the majority of expenditures are made in U.S. Dollars. Transactions involving other currencies during the year are converted into U.S. Dollars using the exchange rates in effect at the time of the transactions. As of the balance sheet dates, monetary assets and liabilities that are denominated in currencies other than the U.S. Dollar are translated to reflect the year-end exchange rates. Resulting gains or losses are reflected separately in the accompanying consolidated statements of operations.

(d) Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives and impairment of Vessels, drydocking, purchase price allocation and income taxes.

(e) Revenues and Operating Expenses

The Partnership recognizes revenues from time charters and bareboat charters as operating leases on a straight-line basis over the term of the charter, net of any commissions. Under time charters, revenue is not recognized during days the Vessel is off-hire. Revenue is recognized from delivery of the Vessel to the charterer, until the end of the contract period. Under time charters, the Partnership is responsible for providing the crewing and other services related to the Vessel's operations, the cost of which is included in the daily hire rate, except when off-hire. Under bareboat charters, the Partnership provides a specified Vessel for a fixed period of time at a specified day rate. Where the term of the contract is based on the duration of a single voyage, the partnership evaluates whether the voyage contain leases and if so recognize lease revenue as described above, and when not, recognizes revenue ASC 606 over time on a load-to-discharge basis.

Voyage expenses are all expenses unique to a particular voyage, including bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls and agency fees. Voyage expenses are paid by the customer under time charter and bareboat charters. Voyage expenses are paid by the Partnership for spot contracts and during periods of off-hire and are recognized when incurred.

Vessel operating expenses include crewing, repairs and maintenance, insurance, stores, lube oils and communication expenses. Vessel operating expenses are paid by the Partnership for time charters, spot contracts and during off-hire and are recognized when incurred.

As further discussed in Note 18—Related Party Transactions, related parties have provided the management services for the Vessels and employ the crews that work on the Vessels. The Partnership has no direct employees and, accordingly, is not liable for any pension or post-retirement benefits.

(f) Financial Income (Expense)

Other finance expense includes external bank fees, commitment fees paid on undrawn revolving credit facility, financing service fees paid to related parties and guarantee commissions paid to external and related parties in connection with the Partnership’s debt and other bank services.

(g) Cash and Cash Equivalents

The Partnership considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

(h) Restricted Cash

Restricted cash consists of bank deposits, which may only be used to settle principal payments under the Partnership’s Vessel financing arrangements.

(i) Trade Accounts Receivable

Accounts receivable are recorded at the invoiced amount and do not bear interest. Under terms of the current time charters and bareboat charters, the customers are committed to pay for the full month’s charter the first day of each month. See Note 2(s)—Prepaid Charter. The allowance for doubtful accounts is the Partnership’s best estimate of the amount of probable credit losses in existing accounts receivable. The Partnership establishes provisions for doubtful accounts on a case-by-case basis when it is unlikely that required payments of specific amounts will occur. In establishing these provisions, the Partnership considers the financial condition of the customer as well as specific circumstances related to the receivable. Receivable amounts determined to be unrecoverable are written-off. There were no allowances for doubtful accounts or amounts written off against the allowance for doubtful accounts as of December 31, 2018 and 2017. The Partnership does not have any off-balance-sheet credit exposure related to its customers.

(j) Inventories

Inventories, which are comprised principally of lubricating oils, are stated at the lower of cost or net realizable value. For vessels on time charters or bareboat charters, there are no bunkers, as the charterer supplies the bunkers, which principally consist of fuel oil. Cost is determined using the first-in, first-out method for all inventories.

(k) Other Current Assets

Other current assets principally consist of prepaid expenses and other receivables.

(l) Vessels and Equipment

Vessels and equipment are stated at the historical acquisition or construction cost, including capitalized interest, supervision and technical and delivery cost, net of accumulated depreciation and impairment loss, if any. Expenditures for subsequent conversions and major improvements are capitalized, provided that such costs increase the earnings capacity or improve the efficiency or safety of the vessels.

Generally, the Partnership drydocks each vessel every 60 months until the vessel is 15 years old and every 30 months thereafter, as required for the renewal of certifications issued by classification societies. For vessels operating on time charters, the Partnership capitalizes the costs directly associated with the classification and regulatory requirements for inspection of the vessels and improvements incurred during drydocking. Drydock cost is depreciated on a straight-line basis over the period until the next planned drydocking takes place. The Partnership expenses costs related to routine repairs and maintenance performed during drydocking or as otherwise incurred. For vessels that are newly built or acquired, an element of the cost of the vessel is initially allocated to a drydock component and depreciated on a straight-line basis over the period until the next planned drydocking. When significant drydocking expenditures occur prior to the expiration of this period, the Partnership expenses the remaining balance of the original drydocking cost in the month of the subsequent drydocking. For vessels operating on bareboat charters, the charterparty bears the cost of any drydocking.

Depreciation on vessels and equipment is calculated on a straight-line basis over the asset’s estimated useful life, less an estimated residual value, as follows:

 

 

 

 

 

    

Useful Life

Hull

 

25 years

Anchor-handling, loading and unloading equipment

 

25 years

Main/auxiliary engine

 

25 years

Thruster, dynamic positioning systems, cranes and other equipment

 

25 years

Drydock costs

 

2.5 – 5 years

 

A Vessel is depreciated to its estimated residual value, which is calculated based on the weight of the ship and estimated steel price. Any cost related to the disposal is deducted from the residual value.

(m) Capitalized Interest

Interest expense incurred on the Partnership’s debt during the construction of the Vessels exceeding one year is capitalized during the construction period.

(n) Impairment of Long-Lived Assets

Vessels and equipment, vessels under construction and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Partnership first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

(o) Goodwill and Intangibles

The Partnership allocates the cost of acquired companies to the identifiable tangible and intangible assets and liabilities acquired, with the remaining amount being classified as goodwill. Goodwill is not amortized but is reviewed for impairment annually or more frequently if impairment indicators are identified.

The Partnership tests goodwill for impairment using a two-step analysis, with the option of performing a qualitative assessment before performing the first step of the two-step analysis, whereby the carrying value of the reporting unit is compared to its fair value in the first step. If the carrying value of the reporting unit is greater than its fair value, the second step is performed, where the implied fair value of goodwill is compared to its carrying value. An impairment charge is recognized for the amount by which the carrying amount of goodwill exceeds its fair value. The fair value is estimated using the net present value of discounted cash flows of the reporting unit. The Partnership has only one reporting unit.

Intangible assets represent contractual rights for charters obtained in connection with business and asset acquisitions that have favorable contractual terms relative to market as of the acquisition dates. Contract liabilities represent contractual rights obtained in connection with business acquisitions that have unfavorable contractual terms relative to market as of the acquisition dates. The favorable and unfavorable contract rights have definite lives and are amortized to revenues over the period of the related contracts. Intangible assets with a definite life are tested for impairment whenever events or circumstances indicate that their carrying amount may not be recoverable. An impairment loss is recognized if the carrying amount exceeds the estimated fair value of the asset.

The contract related intangible assets and liabilities and their amortization periods at acquisition dates are as follows:

 

 

 

 

Intangible category

    

Amortization Period

Above market time charter-Tordis Knutsen

 

4.8 years

Above market time charter-Vigdis Knutsen

 

4.9 years

Unfavorable contractual rights-Fortaleza Knutsen

 

12 years

Unfavorable contractual rights-Recife Knutsen

 

12 years

 

The intangible for the above market value of the time charter contract associated with the Tordis Knutsen is amortized to time charter revenue on a straight line basis over the remaining term of the contract of approximately 4.8 years as of the acquisition date. The intangible for the above market value of the time charter contract associated with the Vigdis Knutsen is amortized to time charter revenue on a straight line basis over the remaining term of the contract of approximately 4.9 years as of the acquisition date.

The unfavorable contractual rights for charters associated with Foraleza Knutsen and Recife Knutsen were obtained in connection with a step acquisition in 2008 that had unfavorable contractual terms relative to market as of acquisition date. The Fortaleza Knutsen and the Recife Knutsen commenced on their 12 years’ fixed bareboat charters in March 2011 and August 2011, respectively. The unfavorable contract rights related to Fortaleza Knutsen and Recife Knutsen are amortized to bareboat revenues on a straight line basis over the 12 years’ contract period that expires in March 2023 and August 2023, respectively.

(p) Debt Issuance Costs

Debt issuance costs, including fees, commissions and legal expenses, are deferred and presented net of debt. Debt issuance costs of term loans are amortized over the term of the relevant loan. Amortization of debt issuance costs is included in interest expense. These costs are presented as a deduction from the corresponding liability, consistent with debt discount.

(q) Derivative Instruments

The Partnership uses derivatives to reduce market risks associated with its operations. The Partnership uses interest rate swaps for the management of interest risk exposure. The interest rate swaps effectively convert a portion of the Partnership’s debt from a floating to a fixed rate over the life of the transactions without an exchange of underlying principal.

The Partnership seeks to reduce its exposure to fluctuations in foreign exchange rates through the use of foreign currency forward contracts.

All derivative instruments are initially recorded at fair value as either assets or liabilities in the accompanying consolidated balance sheets and subsequently measured to fair value. The Partnership does not apply hedge accounting to its derivative instruments. Changes in the fair value of the derivative instruments are recognized in earnings. Gains and losses from the interest rate swap contracts of the Partnership related to long-term mortgage debt and foreign exchange forward contracts are recorded in realized and unrealized gain (loss) on derivative instruments in the consolidated statements of operations. Cash flows related to interest rate swap contracts are presented as cash flows provided by operating activities. Cash flows related to foreign exchange forward contracts entered into to economically hedge operating expenses in currencies other than U.S. Dollars are presented as cash flows provided by operating activities in the consolidated statements of cash flows, while cash flows related to foreign exchange forward contracts entered into to hedge contractual obligations to pay the shipyard in currencies other than functional currency of U.S. Dollars are presented as cash flows used in investing activities in the consolidated statements of cash flows.

(r) Income Taxes

Historically, part of the Partnership’s activities were subject to ordinary taxation and taxes were paid on taxable income (including operating income and net financial income and expense), while part of the activities were subject to the Norwegian Tonnage Tax Regime (the “tonnage tax regime”). Under the tonnage tax regime, the tax is based on the tonnage of the vessel, and operating income is tax free. The net financial income and expense remains taxable as ordinary income tax for entities subject to the tonnage tax regime. Income taxes arising from the part of activities subject to ordinary taxation are included in income tax expense in the consolidated statements of operations. For the portion of activities subject to the tonnage tax regime, tonnage taxes are classified as vessel operating expenses while the current and deferred taxes arising on net financial income and expense are reflected as income tax expense in the consolidated statements of operations. The amounts of tonnage tax included in operating expenses for the years ended December 31, 2018, 2017 and 2016 were $0.3 million, $0.2 million and $0.2 million, respectively.

The Partnership accounts for deferred income taxes using the liability method. Under the liability method, deferred tax assets and liabilities are recognized for the anticipated future tax effects of temporary differences between the financial statement basis and the tax basis of the Partnership’s assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. A valuation allowance for deferred tax assets is recorded when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized.

Recognition of uncertain tax positions is dependent upon whether it is more-likely-than-not that a tax position taken or expected to be taken in a tax return will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. If a tax position meets the more-likely-than-not recognition threshold, it is measured to determine the amount of benefit to recognize in the financial statements based on U.S. GAAP guidance. The Partnership recognizes interest and penalties related to uncertain tax positions in income tax expense.

(s) Prepaid Charter

Under terms of the time charters and bareboat charters, the customer pays for the month’s charter the first day of each month that is recorded as prepaid charter revenues.

(t) Commitments, Contingencies and Insurance Proceeds

Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. See Note 19—Commitments and Contingencies.

Insurance claims for property damage for recoveries up to the amount of loss recognized are recorded when the claims submitted to insurance carriers are probable of recovery. Claims for property damage in excess of the loss recognized and for loss of hire are considered gain contingencies, which are generally recognized when the proceeds are received.

(u) Fair Value Measurements

The Partnership utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Partnership determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

·

Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

·

Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

·

Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

(v) Recently Adopted Accounting Standards

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606), as subsequently updated by the FASB, which provides new authoritative guidance on the methods of revenue recognition and related disclosure requirements. This new standard supersedes existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. This update creates a five-step model and requires a company to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligation in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue as each performance obligation is satisfied. Under the new standard, additional qualitative and quantitative disclosures are required. Effective January 1, 2018, the Partnership adopted the requirements of ASC 606 to new and existing contracts not yet completed as of January 1, 2018, using the modified retrospective approach where the cumulative effect of initially applying the standard is recorded as an adjustment to the opening balance of equity. The Partnership made an assessment on the various implementation aspects of ASU 2014-09 and its amendments, and since there are no changes to the timing or amount of revenue recognized, the Partnership has concluded that the effect of the implementation of this new standard will cause no material cumulative effect to the Partnership’s historical or future financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Partnership adopted this ASU prospectively from January 1, 2018. As a result, this increases the likelihood that future dropdowns of Vessels may be considered the acquisition of an asset rather than a business combination.

On March 1, 2018, the partnership’s wholly owned subsidiary, KNOT Shuttle tankers AS, acquired KNOT’s 100% interest in KNOT Shuttle Tankers 30 AS (“KNOT 30”), the company that owns and operates the Anna Knutsen. Following the adoption of ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, the Partnership accounted for this acquisition as an acquisition of an asset. The cost of the group of assets acquired in the asset acquisition has been allocated to the individual assets acquired or liabilities assumed based on their relative fair values. See the Note 21—Acquisitions.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The new guidance clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The Partnership adopted this ASU on January 1, 2018. The Partnership's adoption of this standard did not have a material impact on the Partnership's consolidated statement of cash flows or related disclosures.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash, which requires that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts presented on the statement of cash flows. The standard eliminates the presentation of transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. Additional disclosures are required for the nature of the restricted cash and restricted cash equivalents. The Partnership adopted this ASU on January 1, 2018 under a retrospective approach. The Partnership's adoption of this standard did not have a material impact on the Partnership's consolidated statement of cash flows or related disclosures.

There are no other recent accounting pronouncements, whose adoption had a material impact on the consolidated financial statements in the current year.

(w) New Accounting Standards Not Yet Adopted

In February 2016, the FASB issued ASU 2016-02, Leases (ASC 842). The objective is to establish the principles that lessors and lessees shall apply to report useful information to users of financial statements about the amount, timing and uncertainty of cash flows arising from a lease. The Partnership is the lessor for its Vessels that operate on time charters and bareboat charters. Accounting by a lessor is largely unchanged from the previous standard. The Partnership does not have any material leased assets. A lessee will be required to recognize in its balance sheet a lease liability to make lease payments and a right-of-use asset. The standard requires a modified retrospective transition method for all entities and the standard provides for optional practical expedients in implementing the standard under the modified retrospective approach.

In July 2018, the FASB issued targeted improvements to the leasing guidance allowing for an additional optional transition method that allow entities to initially apply the new lease standard and its disclosures at the transition date and recognize a cumulative-effect adjustment to the opening balance of retained earnings. The Partnership has elected to use this optional transition approach. The standard is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. The Partnership will adopt ASC 842 and implement the revised guidance as of January 1, 2019. The Partnership will apply the package of practical expedients, but not the hindsight practical expedients since the use of hindsight practical expedient only impacts lease classification if the package of practical expedients is not elected. The Partnership will not reassess whether any expired or existing contracts are, or contain leases, will not reassess lease classification, and will not reassess initial direct costs for any existing leases. Additionally, the practical expedient of disregarding short-term leases for agreements with lease terms of 12 months or less as a lessee and the expedient of not separating lease components from non-lease components will be used for all classes of underlying assets in the Partnership. Based upon assessments performed to date, the Partnership does not expect material effects on the accounting for existing leases applied in the consolidated financial statements where the Partnership is the lessor. Under ASU 2016-02, the Partnership will recognize a right-of-use asset and a lease liability on the balance sheet for certain leases where the Partnership is the lessee based on the present value of future minimum lease payments, whereas currently no right-of-use asset or lease liability is recognized. Based on the analysis performed by the Partnership to date, the right of use asset and lease liability to be recognized on January 1, 2019 is expected not to be material.

3) Formation Transactions and Initial Public Offering

During April 2013, the following transactions occurred in connection with KNOT’s transfer of the interests in KNOT Shuttle Tankers AS and the subsequent IPO:

Capital Contribution

(i)

KNOT contributed to the Partnership’s subsidiary KNOT Offshore Partners UK LLC (“KNOT UK”) its 100% interest in KNOT Shuttle Tankers AS, which directly or indirectly owned (1) Knutsen Shuttle Tankers XII KS, the owner of the Recife Knutsen and the Fortaleza Knutsen , (2) Knutsen Shuttle Tankers XII AS, the general partner of Knutsen Shuttle Tankers XII KS, and (3) the Windsor Knutsen and the Bodil Knutsen and all of their related charters, inventory and long-term debt. This was accounted for as a capital contribution by KNOT to the Partnership.

Recapitalization of the Partnership

(ii)

The Partnership issued to KNOT 8,567,500 subordinated units, representing a 49.0% limited partner interest in the Partnership, and 100% of the incentive distribution rights (“IDRs”), which entitle KNOT to increasing percentages of the cash the Partnership distributes in excess of $0.43125 per unit per quarter.

(iii)

The Partnership issued 349,694 general partner units to the General Partner representing a 2.0% general partner interest in the Partnership.

Initial Public Offering

(iv)

In connection with the IPO, the Partnership issued and sold to the public, through the underwriters, 8,567,500 common units (including 1,117,500 common units sold pursuant to the full exercise of the underwriters’ option to purchase additional units), representing a 49.0% limited partner interest in the Partnership. The price per common unit in the IPO was $21.00. The Partnership received gross proceeds of approximately $179.9 million in connection with the IPO. Expenses relating to the IPO, including, among other things, incremental costs directly attributable to the IPO, were deferred and charged against the gross proceeds of the IPO, whereas other costs were expensed as incurred. The net proceeds of the IPO (approximately $160.7 million, after deducting underwriting discounts, commissions and structuring fees and offering expenses payable by the Partnership) were used by the Partnership to make a cash distribution to KNOT of approximately $21.95 million (which equals net proceeds from the underwriters’ option exercised in full after deducting the underwriting discounts and commissions), to repay approximately $118.9 million of outstanding debt and pre-fund approximately $3.0 million of the Partnership’s one-time entrance tax into the Norwegian tonnage tax regime. The remainder of the net proceeds was made available for general partnership purposes.

Agreements

In connection with the IPO, at or prior to the closing of the IPO, the Partnership entered into several agreements, including:

·

An Administrative Services Agreement with KNOT UK, pursuant to which:

·

KNOT UK agreed to provide to the Partnership administrative services; and

·

KNOT UK is permitted to subcontract certain of the administrative services provided under the administrative services agreement to Knutsen OAS (UK) Ltd. (“KOAS UK”) and Knutsen OAS Shipping AS (“KOAS”), both wholly owned subsidiaries of TS Shipping Invest AS (“TSSI”);

·

Amended Technical Management Agreements with KNOT Management AS (“KNOT Management”), a wholly owned subsidiary of KNOT, that govern the crew, technical and commercial management of the vessels in the fleet;

·

A Contribution and Sale Agreement with KNOT pursuant to which the Partnership acquired the entities that comprised its initial fleet;

·

Amendments to certain of the Partnership’s existing vessel financing agreements to permit the transactions pursuant to which the Partnership acquired its initial fleet in connection with the IPO and to include a $20.0 million revolving credit facility; and

·

An Omnibus Agreement with KNOT, the General Partner and the other parties thereto governing, among other things:

·

To what extent the Partnership and KNOT may compete with each other;

·

The Partnership’s option to purchase the Carmen Knutsen, the Hilda Knutsen , the Torill Knutsen , the Ingrid Knutsen and the Raquel Knutsen from KNOT;

·

Certain rights of first offer on shuttle tankers operating under charters of five or more years;

·

The provision of certain indemnities to the Partnership by KNOT; and

·

KNOT’s guarantee of the payment of the hire rate under the existing Bodil Knutsen and Windsor Knutsen charters for a period of five years following the closing date of the IPO.

5) Significant Risks and Uncertainties Including Business and Credit Concentrations

Each of the Vessels is employed under long-term fixed rate charters, which mitigates earnings risk. The Partnership’s operational results are dependent on the worldwide market for shuttle tankers and timing of entrance into long-term charters. Market conditions for shipping activities are typically volatile, and, as a consequence, the hire rates may vary from year to year. The market is mainly dependent upon two factors: the supply of vessels and the overall growth in the world economy. The general supply of vessels is impacted by the combination of newbuilds, demolition activity of older vessels and legislation that limits the use of older vessels or new standards for vessels used in specific trades.

As of December 31, 2018, all of the Partnership’s Vessel crews, which are employed through KOAS were represented by collective bargaining agreements that are renegotiated annually, or bi-annually.

The Partnership did not incur any loss relating to its customers during the years ended December 31, 2018, 2017 and 2016.

The following table presents time charter and bareboat revenues and percentage of revenues for customers that accounted for more than 10% of the Partnership’s revenues during the years ended December 31, 2018, 2017 and 2016. All of these customers are subsidiaries of major international oil companies.

The Partnership has financial assets that expose it to credit risk arising from possible default by a counterparty. The Partnership considers its counterparties to be creditworthy banking and financial institutions and does not expect any significant loss to result from non-performance by such counterparties. The maximum loss due to credit risk that the Partnership would incur if counterparties failed completely to perform would be the carrying value of cash and cash equivalents, and derivative assets. The Partnership, in the normal course of business, does not demand collateral from its counterparties.

The minimum contractual future revenues should not be construed to reflect total charter hire revenues for any of the years. Minimum contractual future revenues are calculated based on certain assumptions such as operating days per year. In addition, minimum contractual future revenues presented in the table above have not been reduced by estimated off-hire time for periodic maintenance. The amounts may vary given unscheduled future events such as vessel maintenance.

The Partnership’s fleet as of December 31, 2018 consisted of:

7) Segment Information

The Partnership has not presented segment information as it considers its operations to occur in one reportable segment, the shuttle tanker market. At December 31, 2018, the Partnership’s fleet operated under twelve time charters and four bareboat charters. At December 31, 2017, the Partnership’s fleet operated under eleven time charters and four bareboat charters and at December 31, 2016, the Partnership’s fleet operated under seven time charters and four bareboat charters. See Note 5—Significant Risks and Uncertainties Including Business and Credit Concentrations for revenues from customers accounting for over 10% of the Partnership’s consolidated revenue. In both time charters and bareboat charters, the charterer, not the Partnership, controls the choice of which trading areas the Vessels will serve. Accordingly, the Partnership’s management, including the chief operating decision makers, does not evaluate performance according to geographical region.

Raquel Knutsen

In February 2017, the Raquel Knutsen damaged its propeller hub. As a result, the Vessel was off-hire from February 22, 2017 to May 15, 2017 for repairs. Under the Partnership’s loss of hire policies, its insurer will pay the Partnership the hire rate agreed in respect of each vessel for each day, in excess of 14 deductible days, for the time that the Vessel is out of service as a result of damage, for a maximum of 180 days. For the year ended December 31, 2017, the Partnership received payments for loss of hire insurance of $3.4 million which was recorded as a component of total revenues since day rates are recovered under terms of the policy.

In addition, for the year ended December 31, 2017, the Partnership recorded $3.9 million for recoveries up to the amount of loss under hull and machinery insurance for the repairs as a result of the propeller hub damage to the Raquel Knutsen. This is classified under vessel operating expense along with cost of the repairs of $4.2 million for the period, resulting in a net expense of $0.3 million. See Note 19—Commitments and Contingencies.

Carmen Knutsen

During the fourth quarter of 2017, the Carmen Knutsen undertook her 5‑year special drydocking survey. During dismantling for overhaul, a technical default with her controllable pitch propeller was found. As a result, the Vessel went to a different yard to complete the repair. Repairs were completed and the Vessel was back on hire on January 1, 2018. The additional off-hire and technical costs were subject to an insurance claim. Under its loss of hire insurance policies, the Partnership’s insurer is expected to pay the hire rate agreed in respect of the Carmen Knutsen for each day in excess of 14 deductible days while the Vessel was off-hire as a result of the repairs of the controllable pitch propeller. For the years ended December 31, 2018 and 2017, the Partnership recorded $0.45 million and $1.75 million, respectively, for loss of hire which were recorded as a component of total revenues since day rates are recovered under the terms of the policy.

For the year ended December 31, 2017, the Partnership recorded $2.40 million to  vessel operating expense as an estimate of the cost of repairs of the controllable pitch propeller. During 2018, an additional repair cost of $0.15 million was recorded to vessel operating expenses. As of December 31, 2018, the Partnership has received payments and recorded $2.25 million for hull and machinery repairs, resulting in a net expense of $0.30 million.

Interest Rate Risk Management

The consolidated financial statements include the results of interest rate swap contracts to manage the Partnership’s exposure related to changes in interest rates on its variable rate debt instruments and the results of foreign exchange forward contracts to manage its exposure related to changes in currency exchange rates on its operating expenses, mainly crew expenses, in currency other than the U.S. Dollar and on its contract obligations. The Partnership does not apply hedge accounting for derivative instruments. The Partnership does not speculate using derivative instruments.

By using derivative financial instruments to economically hedge exposures to changes in interest rates, the Partnership exposes itself to credit risk and market risk. Derivative instruments that economically hedge exposures are used for risk management purposes, but these instruments are not designated as hedges for accounting purposes. Credit risk is the failure of the counterparty to perform under the terms of the derivative instrument. When the fair value of a derivative instrument is positive, the counterparty owes the Partnership, which creates credit risk for the Partnership. When the fair value of a derivative instrument is negative, the Partnership owes the counterparty, and, therefore, the Partnership is not exposed to the counterparty’s credit risk in those circumstances. The Partnership minimizes counterparty credit risk in derivative instruments by entering into transactions with major banking and financial institutions. The derivative instruments entered into by the Partnership do not contain credit risk-related contingent features. The Partnership has not entered into master netting agreements with the counterparties to its derivative financial instrument contracts.

Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates, currency exchange rates or commodity prices. The market risk associated with interest rate contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.

The Partnership assesses interest rate risk by monitoring changes in interest rate exposures that may adversely impact expected future cash flows and by evaluating economical hedging opportunities.

The Partnership has historically used variable interest rate mortgage debt to finance its vessels. The variable interest rate mortgage debt obligations expose the Partnership to variability in interest payments due to changes in interest rates. The Partnership believes that it is prudent to limit the variability of a portion of its interest payments. To meet this objective, the Partnership entered into London Interbank Offered Rate (“LIBOR”) based interest rate swap contracts to manage fluctuations in cash flows resulting from changes in the benchmark interest rate of LIBOR. These swaps change the variable rate cash flow exposure on the mortgage debt obligations to fixed cash flows. Under the terms of the interest rate swap contracts, the Partnership receives LIBOR-based variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent of fixed rate debt for the notional amount of its debt hedged.

As of December 31, 2018 and 2017, the total notional amount of the Partnership’s outstanding interest rate swap contracts that were entered into in order to hedge outstanding or forecasted debt obligations were $555.5 million and $650.5 million, respectively. As of December 31, 2018 and 2017 the carrying amount of the interest rate swaps contracts were net assets of $15.9 million and $9.7 million, respectively. See Note 11—Fair Value Measurements.

Changes in the fair value of interest rate swap contracts are reported in realized and unrealized gain (loss) on derivative instruments in the same period in which the related interest affects earnings.

The Partnership and its subsidiaries utilize the U.S. Dollar as their functional and reporting currency, because all of their revenues and the majority of their expenditures, including the majority of their investments in vessels and their financing transactions, are denominated in U.S. Dollars. Payment obligations in currencies other than the U.S. Dollar, and in particular operating expenses in NOK, expose the Partnership to variability in currency exchange rates. The Partnership believes that it is prudent to limit the variability of a portion of its currency exchange exposure. To meet this objective, the Partnership entered into foreign exchange forward contracts to manage fluctuations in cash flows resulting from changes in the exchange rates towards the U.S. Dollar. The agreements change the variable exchange rate to fixed exchange rates at agreed dates.

As of December 31, 2018 and 2017, the total contract amount in foreign currency of the Partnership’s outstanding foreign exchange forward contracts that were entered into to economically hedge outstanding future payments in currencies other than the U.S. Dollar were NOK 244.2 million and NOK 249.9 million, respectively. As of December 31, 2018 and 2017, the carrying amount of the Partnership’s foreign exchange forward contracts was a net liability of $1.7 million and a net assets of $0.6 million, respectively. See Note 11—Fair Value Measurements.

11) Fair Value Measurements

(a) Fair Value of Financial Instruments

The following table presents the carrying amounts and estimated fair values of the Partnership’s financial instruments as of December 31, 2018 and 2017. Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The carrying amounts shown in the table above are included in the consolidated balance sheets under the indicated captions. Carrying amount of long-term debt, current and non-current, above excludes capitalized debt issuance cost of $10.1 million and $6.7 million as of December 31, 2018 and 2017, respectively. The carrying value of trade accounts receivable, trade accounts payable and receivables/payables to owners and affiliates approximate their fair value.

The fair values of the financial instruments shown in the above table as of December 31, 2018 and 2017 represent the amounts that would be received to sell those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants at that date. Those fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Partnership’s own judgment about the assumptions that market participants would use in pricing the asset or liability. Those judgments are developed by the Partnership based on the best information available in the circumstances, including expected cash flows, appropriately risk-adjusted discount rates and available observable and unobservable inputs.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments:

·

Cash and cash equivalents and restricted cash: The fair value of the Partnership’s cash balances approximates the carrying amounts due to the current nature of the amounts. As of December 31, 2018 and 2017 there is no restricted cash.

·

Foreign exchange forward contracts: The fair value is calculated using mid-rates (excluding margins) as determined by counterparties based on available market rates as of the balance sheet date. The fair value is discounted from the value at expiration to the current value of the contracts.

·

Interest rate swap contracts: The fair value of interest rate swap contracts is determined using an income approach using the following significant inputs: (1) the term of the swap contract (weighted average of 4.9 years and 4.5 years, as of December 31, 2018 and 2017, respectively), (2) the notional amount of the swap contract (ranging from $10,037 to $50,000), discount rates interpolated based on relevant LIBOR swap curves; and (3) the rate on the fixed leg of the swap contract (rates ranging from 1.38% to 2.89% for the contracts as of December 31, 2018 and rates ranging from 1.25% to 2.49% for the contracts as of December 31, 2017).

·

Long-term debt: With respect to long-term debt measurements, the Partnership uses market interest rates and adjusts for risks such as its own credit risk. In determining an appropriate spread to reflect its credit standing, the Partnership considered interest rates currently offered to KNOT for similar debt instruments of comparable maturities by KNOT’s and the Partnership’s bankers as well as other banks that regularly compete to provide financing to the Partnership.

(b) Fair Value Hierarchy

The following table presents the placement in the fair value hierarchy of assets and liabilities that are measured at fair value on a recurring basis (including items that are required to be measured at fair value or for which fair value is required to be disclosed) as of December 31, 2018 and 2017:

17) Income Taxes

(a) Components of Current and Deferred Tax Expense

All of the income from continuing operations before income taxes was taxable to Norway and UK for the years ended December 31, 2018, 2017 and 2016. The entities and activities taxable to Norway are subject to the Norwegian tonnage tax regime. Under the Norwegian tonnage tax regime, the tax is based on the tonnage of the vessel, and the operating income is tax free. The net financial income and expense remains taxable as ordinary income tax for entities subject to the tonnage tax regime. See Note 2(r)—Income Taxes. The activities taxable to UK relates to KNOT UK and is based on the operating income for the entity.

The significant components of current and deferred income tax expense attributable to income from continuing operations for the years ended December 31, 2018, 2017 and 2016 are as follows:

The Partnership records a valuation allowance for deferred tax assets when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. The valuation allowances were $17.0 million and $15.7 million as of December 31, 2018 and 2017, respectively. The valuation allowances relate to the financial loss carry forwards and other deferred tax assets for tonnage tax that, in the judgment of the Partnership, are more-likely-than not to be realized reflecting the Partnership’s cumulative loss position for tonnage tax. In assessing the realizability of deferred tax assets, the Partnership considers whether it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized taking into account all the positive and negative evidence available. As of December 31, 2018, the Partnership determined that the deferred tax assets are likely to not be realized, and the booked value was, therefore, zero. There is no expiration date for losses carried forward.

After the reorganization of the Partnership’s predecessor’s activities into the new group structure in February 2013, all profit from continuing operations in Norway is taxable within the tonnage tax regime. The consequence of the reorganization is a one-time entrance tax into the Norwegian tonnage tax regime due to the Partnership’s acquisition of the shares in the subsidiary that owns the Fortaleza Knutsen and the Recife Knutsen . The total amount of the entrance tax was estimated to be approximately $3.0 million, which was recognized in the three months ended March 31, 2013. The entrance tax on this gain is payable over several years and is calculated by multiplying the Norwegian tax rate by the declining balance of the gain, which will decline by 20% each year. The Norwegian corporate tax rate was reduced from 24% in 2017 to 23% in 2018 and will be 22% effective as of January 1, 2019. The entrance tax had declined to approximately $2.7 million at December 31, 2013 due to translation effects and tax rate changes and at December 31, 2014 the entrance tax had declined to approximately $1.8 million due to paid entrance tax, change in tax rate and translation effects. At December 31, 2015 the entrance tax had declined to approximately $1.1 million due to paid entrance tax, change in tax rate and translation effects. At December 31, 2016 the entrance tax had declined to approximately $0.9 million due to paid entrance tax, change in tax rate and translation effects. At December 31, 2017 the entrance tax had declined to approximately $0.7 million due to paid entrance tax, change in tax rate and translation effects. At December 31, 2018 the entrance tax had declined to approximately $0.6 million due to paid entrance tax, change in tax rate and translation effects. The taxes payable, mainly related to the entrance tax, are calculated based on a tax rate of 23% for 2018 and 24% for 2017, and the deferred tax liabilities, also mainly related to the entrance tax, are calculated based on a tax rate of 22% and 23% effective as from January 1, 2019 and January 1, 2018, respectively. Income tax expense within the UK of $18,331 and $11,563 for 2018 and 2017, respectively, was calculated by multiplying the tax basis with the UK tax rate of 20%.

As of December 31, 2018, the total income taxes payable are estimated to be $0.1 million and consist of payable entrance tax and ordinary UK corporation tax. As of December 31, 2017, the total income taxes payable were estimated to be $0.2 million and consist of payable entrance tax and ordinary UK corporation tax.

As of December 31, 2018, approximately $0.1 million of the estimated entrance tax of $0.6 million is estimated to be payable in the first and second quarter of 2019 and is presented as income taxes payable, while $0.5 million is presented as non-current deferred taxes payable. As of December 31, 2017, approximately $0.2 million of the estimated entrance tax of $0.7 million was estimated to be payable in the first and second quarter of 2018 and was presented as income taxes payable, while $0.5 million was presented as non-current deferred taxes payable. Additionally, a tax liability of approximately $0.1 million was recorded as deferred taxes payable and relates to the acquisition of KNOT Shuttle Tankers 26 AS.

The tax loss carry forward from ordinary taxation and financial loss carry forwards for tonnage tax have no expiration dates.

The Partnership’s Norwegian income tax returns are subject to examination by Norwegian tax authorities going back ten years from 2014. The Partnership had no unrecognized tax benefits as December 31, 2018 and 2017. During the years ended December 31, 2018 and 2017, the Partnership did not incur any interest or penalties on its tax return.

On December 14, 2017, the Norwegian government concluded the negotiations with the EFTA Surveillance Authority regarding the Norwegian tonnage tax regime, which has been approved for another ten years, until 2027. Pursuant to the approval, Norway has introduced restrictions that eliminates the ability of companies that own vessels under certain bareboat charters to qualify for the Norwegian tonnage tax regime. Companies that no longer qualify for the Norwegian tonnage tax regime will instead be subject to Norwegian corporate income tax. However, there are no limitations on intra-group bareboat chartering, as well as bareboat charters where crewing services are carried out by a related party. In order to constitute a related party, a minimum of 25% ownership/control is required, according to the “associated enterprise” definition in the ATAD directive (Council Directive EU 2016/1164.) Due to the fact that KNOT has an ownership interest in the Partnership that exceeds 25% as well as an ownership interest of 100% in KNOT Management and KNOT Management Denmark AS which provide services to the Vessels owned by the Partnership which operate on bareboat charters, the Vessels operating on bareboat charters are effectively seen as time charter services to the customer. The services are provided to the charterer. If this related party situation is ended, other alternatives and possibly mitigating measures must be evaluated.

(a) Related Parties

Prior to the IPO, the Partnership’s predecessor operated as an integrated part of KNOT. KNOT is owned 50% by TSSI and 50% by Nippon Yusen Kaisha (“NYK”).

The Windsor Knutsen , the Bodil Knutsen , the Carmen Knutsen , the Hilda Knutsen , the Torill Knutsen , the Ingrid Knutsen , the Raquel Knutsen , the Tordis Knutsen, the Vigdis Knutsen, the Lena Knutsen, the Brasil Knutsen and the Anna Knutsen, all of which operate under time charters, are subject to technical management agreements pursuant to which certain crew, technical and commercial management services are provided by KNOT Management or KNOT Management Denmark AS (“KNOT Management Denmark”). Under these technical management agreements, the Partnership’s subsidiaries pay fees to and reimburse the costs and expenses of KNOT Management. The Fortaleza Knutsen , the Recife Knutsen , the Dan Cisne and the Dan Sabia operate under bareboat charters and, as a result, the customer is responsible for providing the crew, technical and commercial management of the vessel. However, each of these vessels are subject to management and administration agreements with either KNOT Management or KNOT Management Denmark, a 100% owned subsidiary of KNOT, pursuant to which these companies provide general monitoring services for the vessels in exchange for an annual fee.

The Partnership is a party to an administrative services agreement with KNOT UK, pursuant to which KNOT UK provides administrative services, and KNOT UK is permitted to subcontract certain of the administrative services provided under the administrative services agreement to KOAS UK and KOAS. On May 7, 2015, the Partnership entered into an amendment to the administrative services agreement, which allows KNOT UK to also subcontract administrative services to KNOT Management. Effective as of February 26, 2018, the Partnership entered into a second amendment to the administrative services agreement extending the term of the agreement indefinitely, subject to termination by any party upon 90 days’ notice for any reason.

The amounts of such costs and expenses included in the consolidated statements of operations for the years ended December 31, 2018, 2017 and 2016 are as follows:

(1)

Guarantee income from KNOT:  Pursuant to the Omnibus Agreement, KNOT agreed to guarantee the payments of the hire rate under the initial charter of the Bodil Knutsen and Windsor Knutsen for a period of five years from the closing date of the IPO (until April 15, 2018). In October 2015, the Windsor Knutsen commenced on a new Shell time charter with a hire rate below the hire rate in the initial charter. The difference between the new hire rate and the initial rate was paid by KNOT until April 15, 2018. The Vigdis Knutsen suffered damages to its hull in connection with a ship-to-ship loading on May 24, 2017 and the vessel went off-hire 6 days in June 2017 due to repairs of the damage. In connection with the Vigdis Knutsen acquisition, KNOT agreed to pay for the repair cost and charter hire lost in connection with the incident. The reimbursement from KNOT for lost charter hire is accounted for as guarantee income. See Note 18(b)—Related Party Transactions—Guarantees and Indemnifications.

(2)

Technical and operational management fee from KNOT Management or KNOT Management Denmark to Vessels: KNOT Management or KNOT Management Denmark provides technical and operational management of the vessels on time charter including crewing, purchasing, maintenance and other operational service. In addition, there is also a charge for 24‑hour emergency response services provided by KNOT Management for all vessels managed by KNOT Management.

(3)

Administration fee from KNOT Management and Knutsen OAS Shipping AS (“KOAS”) and Knutsen OAS (UK) Ltd. (“KOAS UK”): Administration costs include the compensation and benefits of KNOT Management’s management and administrative staff as well as other general and administration expenses. Some benefits are also provided by KOAS and KOAS UK. Net administration costs are total administration cost plus a 5% margin, reduced for the total fees for services delivered by the administration staffs and the estimated shareholder costs for KNOT that have not been allocated. As such, the level of net administration costs as a basis for the allocation can vary from year to year based on the administration and financing services offered by KNOT to all the vessels in its fleet each year. KNOT Management also charges each subsidiary a fixed annual fee for the preparation of the statutory financial statement.

(4)

Administration and management fee from KNOT Management and KNOT Management Denmark: For bareboat charters, the shipowner is not responsible for providing crewing or other operational services and the customer is responsible for all vessel operating expenses and voyage expenses. However, each of the vessels under bareboat charters is subject to a management and administration agreement with either KNOT Management or KNOT Management Denmark, pursuant to which these companies provide general monitoring services for the vessels in exchange for an annual fee.

(5)

Interest expense charged from KNOT: KNOT invoiced interest (expense) income for any outstanding payables to (receivable from) owners and affiliates to the vessel-owning subsidiaries.

(b) Guarantees and Indemnifications

Pursuant to the Omnibus Agreement, KNOT agreed to guarantee the payments of the hire rate under the initial charters of each of the Windsor Knutsen and the Bodil Knutsen for a period of five years from the closing date of the IPO (until April 15, 2018).

In April 2014, the Partnership was notified that Shell would not exercise its option to extend the Windsor Knutsen time charter after the expiration of its initial term. The vessel was re-delivered on July 28, 2014. In order to comply with its obligations under the Omnibus Agreement, on July 29, 2014, KNOT and the Partnership entered into a time charter for the vessel at a rate of hire that would have been in effect during the option period under the previous Shell time charter. This charter was effective until the new Shell time charter commenced in October 2015. The new Shell charter has a hire rate that is lower than the hire rate in the initial charter. The difference between the new hire rate and the initial rate was paid by KNOT until April 15, 2018.

On June 1, 2017, the Partnership acquired KNOT’s 100% interest in KNOT Shuttle Tankers 25 AS, the company that owns and operate the Vigdis Knutsen. Shortly before the closing of the acquisition and on May 24, 2017, the Vigdis Knutsen suffered damages to its hull in connection with a ship-to-ship loading and the vessel went off-hire 6 days in June 2017 due to repairs of the damage. In connection with the Vigdis Knutsen acquisition, KNOT agreed to pay for the repair cost and charter hire lost in connection with the incident.

Under the Omnibus Agreement, KNOT agreed to indemnify the Partnership until April 15, 2018 (or for a period of at least three years after the purchase of the Hilda Knutsen , the Torill Knutsen , the Ingrid Knutsen and the Raquel Knutsen , as applicable), against certain environmental and toxic tort liabilities with respect to certain assets that KNOT contributed or sold to the Partnership to the extent arising prior to the time they were contributed or sold. However, claims are subject to a deductible of $0.5 million and an aggregate cap of $5 million.

(c) Transactions with Management and Directors

Trygve Seglem, the Chairman of the Partnership’s board of directors and the President and CEO of KNOT, controls Seglem Holding AS, which owns 100% of the equity interest in TSSI, which controls KOAS. TSSI owns 50% of the equity interest in KNOT. NYK, which owns 50% of the equity interest in KNOT, has management and administrative personnel on secondment to KNOT.

See the footnotes to Note 18(a)—Related Party Transactions—Related Parties for a discussion of the allocation principles for KNOT’s administrative costs, including management and administrative staff, included in the consolidated statements of operations.

Directors each receive a director fee of $50,000 per year. Members of the audit and conflicts committees each receive a committee fee of $12,000 and the Chairman of such committees receive an additional fee of $3,000 per year.

(f) Acquisitions from KNOT

On December 1, 2016, the Partnership acquired KNOT’s 100% interest in Knutsen Shuttle Tankers 19 AS, the company that owns and operates the Raquel Knutsen . As part of the financing for the purchase of the Raquel Knutsen, KNOT provided the $25.0 million Seller’s Credit and Seller’s Loan. The Seller’s Credit and the Seller’s Loan, including accrued interest were repaid in full in January 2017. This acquisition was accounted for as an acquisition of a business.

On March 1, 2017, the Partnership acquired KNOT’s 100% interest in KNOT Shuttle Tankers 24 AS, the company that owns and operates the Tordis Knutsen. This acquisition was accounted for as an acquisition of a business.

On June 1, 2017, the Partnership acquired KNOT’s 100% interest in KNOT Shuttle Tankers 25 AS, the company that owns and operates the Vigdis Knutsen. This acquisition was accounted for as an acquisition of a business.

On September 30, 2017, the Partnership acquired KNOT’s 100% interest in KNOT Shuttle Tankers 26 AS, the company that owns and operates the Lena Knutsen. This acquisition was accounted for as an acquisition of a business.

On December 15, 2017, the Partnership acquired KNOT’s 100% interest in KNOT Shuttle Tankers 32 AS, the company that owns and operates the Brasil Knutsen. This acquisition was accounted for as an acquisition of a business.

On March 1, 2018, the Partnership acquired KNOT’s 100% interest in KNOT Shuttle Tankers 30 AS, the company that owns and operates the Anna Knutsen. This acquisition was accounted for as an acquisition of assets.

The board of directors of the Partnership and the Conflicts Committee of the board approved the purchase price for each transaction described above. The Conflicts Committee retained a financial advisor to assist with its evaluation of each of the transactions. See Note 21—Acquisitions.

19) Commitments and Contingencies

Assets Pledged

As of December 31, 2018 and 2017, Vessels with a book value of $1,767 million and $1,723 million, respectively, were pledged as security held as guarantee for the Partnership’s long-term debt and interest rate swap obligations. See Note 10—Derivative Instruments, Note 13—Vessels and Equipment and Note 16—Long-Term Debt.

Claims and Legal Proceedings

Under the Partnership’s time charters, claims to reduce the hire rate payments can be made if the Vessel does not perform to certain specifications in the agreements. An accrual of $0.4 million for a probable claim was recorded for the year ended December 31, 2017. No accrual for possible claim was recorded for the years ended December 31, 2018 and 2016.

From time to time, the Partnership is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the consolidated financial position, results of operations or cash flows.

Insurance

The Partnership maintains insurance on all the Vessels to insure against marine and war risks, which include damage to or total loss of the Vessels, subject to deductible amounts that average $0.15 million per Vessel, and loss of hire.

Under the loss of hire policies, the insurer will pay a compensation for the lost hire rate agreed in respect of each Vessel for each day, in excess of 14 deductible days, for the time that the Vessel is out of service as a result of damage, for a maximum of 180 days. In addition, the Partnership maintains protection and indemnity insurance, which covers third-party legal liabilities arising in connection with the Vessels’ activities, including, among other things, the injury or death of third-party persons, loss or damage to cargo, claims arising from collisions with other vessels and other damage to other third-party property, including pollution arising from oil or other substances. This insurance is unlimited, except for pollution, which is limited to $1 billion per vessel per incident. The protection and indemnity insurance is maintained through a protection and indemnity association, and as a member of the association, the Partnership may be required to pay amounts above budgeted premiums if the member claims exceed association reserves, subject to certain reinsured amounts. If the Partnership experiences multiple claims each with individual deductibles, losses due to risks that are not insured or claims for insured risks that are not paid, it could have a material adverse effect on the Partnership’s results of operations and financial condition.

Raquel Knutsen

In February 2017, the Raquel Knutsen damaged its propeller hub. As a result, the Vessel was off-hire from February 22, 2017 to May 15, 2017 for repairs. Under the Partnership’s loss of hire policies, its insurer will pay the Partnership the hire rate agreed in respect of each vessel for each day, in excess of 14 deductible days, for the time that the Vessel is out of service as a result of damage, for a maximum of 180 days. For the year ended December 31, 2017, the Partnership received payments for loss of hire insurance of $3.4 million which was recorded as a component of total revenues since day rates are recovered under terms of the policy.

In addition, for the year ended December 31, 2017, the Partnership recorded $3.9 million for recoveries up to the amount of loss under hull and machinery insurance for the repairs as a result of the propeller hub damage to the Raquel Knutsen. This is classified under vessel operating expense along with cost of the repairs of $4.2 million for the period, resulting in a net expense of $0.3 million. See Note 8—Insurance Proceeds.

Carmen Knutsen

During the fourth quarter of 2017, the Carmen Knutsen undertook her 5‑year special drydocking survey. During dismantling for overhaul, a technical default with her controllable pitch propeller was found. As a result, the Vessel went to a different yard to complete the repair. Repairs were completed and the Vessel was back on hire on January 1, 2018. The additional off-hire and technical costs were subject to an insurance claim. Under its loss of hire insurance policies, the Partnership’s insurer is expected to pay the hire rate agreed in respect of the Carmen Knutsen for each day in excess of 14 deductible days while the Vessel was off-hire as a result of the repairs of the controllable pitch propeller. For the years ended December 31, 2018 and 2017, the Partnership recorded $0.45 million and $1.75 million, respectively, for loss of hire which were recorded as a component of total revenues since day rates are recovered under the terms of the policy.

For the year ended December 31, 2017, the Partnership recorded $2.40 million to vessel operating expense as an estimate of the cost of repairs of the controllable pitch propeller. During 2018, an additional repair cost of $0.15 million was recorded to vessel operating expenses. As of December 31, 2018, the Partnership has received payments and recorded $2.25 million for hull and machinery repairs, resulting in a net expense of $0.30 million. See Note 8—Insurance Proceeds.

(1)

Earnings per unit have been calculated in accordance with the cash distribution provisions set forth in the Partnership Agreement.

(2)

This refers to distributions made or to be made in relation to the period irrespective of the declaration and payment dates and based on the numbers of units outstanding at the record date. This includes cash distributions to the IDR holder (KNOT) for the years ended December 31, 2018, 2017 and 2016 of $2.8 million, $2.6 million and $2.4 million, respectively.

(3)

On May 18, 2016, all subordinated units converted into common units on a one-for-one basis.

(4)

Until May 18, 2016, the net income attributable to the IDR holder is included in calculation of earnings per unit for subordinated unitholders, basic and diluted. The IDRs generally were not transferrable by KNOT prior to March 31, 2018. The net income attributable to IDRs for the year ended December 31, 2018, 2017 and 2016 was $2.8 million, $2.6 million and $2.4 million, respectively.

(5)

Refers to cash distributions declared and paid during the period.

(6)

Refers to cash distributions declared and paid subsequent to December 31, 2018.

As of December 31, 2018, 73.5% of the Partnership’s total number of common units outstanding representing limited partner interests were held by the public (in the form of 24,036,226 common units) and 26.2% of such units were held directly by KNOT (in the form of 8,567,500 common units). In addition, KNOT, through its ownership of the General Partner, held a 1.85% general partner interest (in the form of 615,117 general partner units) and a 0.3% limited partner interest (in the form of 90,368 common units).

Earnings per unit – basic is determined by dividing net income, after deducting the amount of net income attributable to the Series A Preferred Units and the distribution paid or to be made in relation to the period by the weighted-average number of units outstanding during the applicable period.

The computation of limited partners’ interest in net income per common unit – diluted assumes the issuance of common units for all potentially dilutive securities consisting of the Series A Preferred Units. Consequently, the net income attributable to limited partners’ interest is exclusive of any distributions on the Series A Preferred Units. In addition, the weigthed average number of common units outstanding has been increased assuming the Series A Preferred Units have been converted to common units using the if-converted method. The computation of limited partners’ interest in net income per common unit – diluted does not assume the issuance of Series A Preferred Units if the effect would be anti-dilutive.

The General Partner’s, common unitholders’ and subordinated unitholders’ interest in net income was calculated as if all net income was distributed according to the terms of the Partnership Agreement, regardless of whether those earnings would or could be distributed. The Partnership Agreement does not provide for the distribution of net income. Rather, it provides for the distribution of available cash, which is a contractually defined term that generally means all cash on hand at the end of each quarter less the amount of cash reserves established by the Partnership’s board of directors (the “Board”) to provide for the proper conduct of the Partnership’s business, including reserves for maintenance and replacement capital expenditures, anticipated credit needs and capital requirements and any accumulated distributions on, or redemptions of, the Series A Preferred Units. In addition, KNOT, as the initial holder of all IDRs, has the right, at the time when there are no subordinated units outstanding and it has received incentive distributions at the highest level to which it is entitled (48.0% for each of the prior four consecutive fiscal quarters), to reset the initial cash target distribution levels at higher levels based on the distribution at the time of the exercise of the reset election. Unlike available cash, net income is affected by non-cash items, such as depreciation and amortization, unrealized gains and losses on derivative instruments and unrealized foreign currency gains and losses.

Distributions of available cash from operating surplus for any quarter are required to be made in the following manner:

·

first , 98.15% to all common unitholders, pro rata, and 1.85% to the General Partner, until each outstanding common unit has received an amount equal to $0.375 (the “MQD”) for that quarter;

·

second , 98.15% to all common unitholders, pro rata, and 1.85% to the General Partner, until each outstanding common unit has received a total of $0.43125 (the “first target distribution”) for that quarter;

·

third , 85.15% to all common unitholders, pro rata, 1.85% to the General Partner, and 13% to the IDR holders, pro rata, until each outstanding common unit has received a total of $0.46875 (the “second target distribution”) for that quarter;

·

fourth , 75.15% to all common unitholders, pro rata, 1.85% to the General Partner, and 23% to the IDR holders, pro rata, until each outstanding common unit has received a total of $0.5625 (the “third target distribution”) for that quarter; and

·

thereafter , 50.15% to all common unitholders, pro rata, 1.85% to the General Partner, and 48% to the IDR holders, pro rata.

The percentage interests set forth above assumed that the General Partner continues to own a 1.85% general partner interest and that the Partnership has not issued additional classes of equity securities.

On February 2, 2017, the Partnership issued and sold in a private placement 2,083,333 Series A Preferred Units at a price of $24.00 per unit. After deducting fees and expenses, the net proceeds from the sale were $48.6 million. The Partnership used the net proceeds from the sale to fund the cash portion of the purchase price of the Tordis Knutsen and to repay debt and for general partnership purposes.

On June 30, 2017, the Partnership (i) issued and sold in a second private placement 1,666,667 additional Series A Preferred Units at a price of $24.00 per unit and (ii) amended and restated its Partnership Agreement to make certain amendments to the terms of the Series A Preferred Units, including the 2,083,333 Series A Preferred Units issued on February 2, 2017. After deducting estimated fees and expenses, the net proceeds of the sale were $38.9 million. The Partnership used $30.0 million of the net proceeds to repay the revolving credit facility, which was drawn in connection with acquisition of the Vigdis Knutsen.

The Series A Preferred Units rank senior to the common units as to the payment of distributions and amounts payable upon liquidation, dissolution or winding up. The Series A Preferred Units have a liquidation preference of $24.00 per unit, plus any Series A unpaid cash distributions, plus all accrued but unpaid distributions on such Series A Preferred Unit with respect to the quarter in which the liquidation occurs to the date fixed for the payment of any amount upon liquidation. The Series A Preferred Units are entitled to cumulative distributions from their initial issuance date, with distributions being calculated at an annual rate of 8.0% on the stated liquidation preference and payable quarterly in arrears within 45 days after the end of each quarter, when, as and if declared by the Board.

The Series A Preferred Units are generally convertible, at the option of the holders of the Series A Preferred Units, into common units commencing on February 2, 2019 at the then applicable conversion rate. The conversion rate will be subject to adjustment under certain circumstances. In addition, the conversion rate will be redetermined on a quarterly basis, such that the conversion rate will be equal to $24.00 (the “Issue Price”) divided by the product of (x) the book value per common unit at the end of the immediately preceding quarter (pro-forma for per unit cash distributions payable with respect to such quarter) multiplied by (y) the quotient of (i) the Issue Price divided by (ii) the book value per common unit on February 2, 2017. In addition, the Partnership may redeem the Series A Preferred Units at any time between February 2, 2019 and February 2, 2027 at the redemption price specified in the Partnership Agreement, provided, however, that upon notice from the Partnership to the holders of Series A Preferred Units of its intent to redeem, such holders may elect, instead, to convert their Series A Preferred Units into common units at the then applicable conversion rate. For the year ended December 31, 2018, the possible conversion of the Series A Preferred Units into common units are included in the calculation of the diluted earnings per unit. See Note 20—Earnings per Unit and Cash Distributions.

Upon a change of control of the Partnership, the holders of Series A Preferred Units will have the right to require cash redemption at 100% of the Issue Price. In addition, the holders of Series A Preferred Units will have the right to cause the Partnership to redeem the Series A Preferred Units on February 2, 2027 in, at the option of the Partnership, (i) cash at a price equal to 70% of the Issue Price or (ii) common units such that each Series A Preferred Unit receives common units worth 80% of the Issue Price (based on the volume-weighted average trading price, as adjusted for splits, combinations and other similar transactions, of the common units as reported on the NYSE for the 30 trading day period ending on the fifth trading day immediately prior to the redemption date) plus any accrued and unpaid distributions. In addition, at any time following February 2, 2019 and subject to certain conditions, the Partnership will have the right to convert the Series A Preferred Units into common units at the then applicable conversion rate if the aggregate market value (calculated as set forth in the partnership agreement) of the common units into which the then outstanding Series A Preferred Units are convertible, based on the then applicable conversion rate, is greater than 130% of the aggregate Issue Price of the then outstanding Series A Preferred Units.

The Series A Preferred Units have voting rights that are identical to the voting rights of the common units, except they do not have any right to nominate, appoint or elect any of the directors of the Board, except whenever distributions payable on the Series A Preferred Units have not been declared and paid for four consecutive quarters (a “Trigger Event”). Upon a Trigger Event, holders of Series A Preferred Units, together with the holders of any other series of preferred units upon which like rights have been conferred and are exercisable, may replace one of the members of the Board appointed by the General Partner with a person nominated by such holders, such nominee to serve until all accrued and unpaid distributions on the preferred units have been paid. The Series A Preferred Units are entitled to vote with the common units as a single class so that the Series A Preferred Units are entitled to one vote for each common unit into which the Series A Preferred Units are convertible at the time of voting.

For additional information about the Series A Preferred Units, please read the Partnership’s Report on Form 8‑A/A filed with the Securities and Exchange Commission on June 30, 2017.

Originally approved on August 12, 2015, the common unit purchase program authorized the Partnership to repurchase up to 666,667 of its common units and the General Partner to purchase up to 333,333 common units of the Partnership. On August 10, 2016, the boards of directors of the Partnership and the General Partner each authorized an extension of the common unit purchase program to August 31, 2017. On August 9, 2017, the boards of directors of the Partnership and the General Partner authorized a further extension of the program to August 31, 2018. As of December 31, 2015, the Partnership and the General Partner had purchased 180,906 and 90,368 common units, respectively, pursuant to the program at an average purchase price of $12.71 per unit. No additional common units had been purchased by the Partnership or the General Partner as of the expiration date of the program on August 31, 2018.

All purchases are made pursuant to a single program and are allocated approximately two-thirds to the Partnership and one-third to the General Partner. There is no obligation to purchase any specific number of common units and the program may be modified, suspended, extended or terminated at any time. Common units repurchased by the Partnership under the program have been cancelled.

The subordination period for the 8,567,500 subordinated units ended on May 18, 2016. All of the subordinated units, which were owned by KNOT, converted to common units on a one-for-one basis.

24) Subsequent Events

The Partnership has evaluated subsequent events from the balance sheet date through April 10, 2019, the date at which the audited consolidated financial statements were available to be issued, and determined that there are no other items to disclose, except as follows:

On February 14, 2019, the Partnership paid a quarterly cash distribution of $0.52 per common unit with respect to the quarter ended December 31, 2018. The aggregate amount of the paid distribution was was 18.0 million. On February 14, 2019, the Partnership also paid a cash distribution to holders of Series A Preferred Units with respect to the quarter ended December 31, 2018 in an aggregate amount equal to $1.8 million.

On November 29, 2018, the Partnership announced that John Costain has decided to resign as Chief Executive Officer and Chief Financial Officer of the Partnership as of May 31, 2019 in order to pursue other interests. The Partnership's Board has approved the appointment of Gary Chapman as the new Chief Executive Officer and Chief Financial Officer of the Partnership commencing June 1, 2019.

On December 17, 2018, the Partnership's subsidiary that owns the Windsor Knutsen and Shell agreed to suspend the vessel's time charter contract for a minimum of 10 months and a maximum of 12 months. The suspension period commenced March 4, 2019. During the suspension period, the Windsor Knutsen will operate under a time charter contract with Knutsen Shuttle Tankers Pool AS, on the same terms as the existing time charter contract with Shell.

Summary of Significant Accounting Policies (Policies)
12 Months Ended
Dec. 31, 2018
Summary of Significant Accounting Policies  
Basis of Preparation

(a) Basis of Preparation

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany balances and transactions are eliminated.

The consolidated financial statements include the financial statements of the entities listed in Note 4—Subsidiaries.

Business Combinations and Asset Acquisitions

(b) Business Combinations and Asset Acquisitions

Business combinations are accounted for under the purchase method of accounting. On acquisition, the identifiable assets, liabilities and contingent liabilities are measured at their fair values at the date of acquisition. Any excess of the cost of acquisition over the fair values of the identifiable net assets acquired is recognized as goodwill. The consideration transferred for an acquisition is measured at fair value of the consideration given. Acquisition related costs are expensed as incurred. The results of operations of the acquired businesses are included in the consolidated results as of the date of the applicable acquisition.

Dependent on the facts and circumstances, the assessment of a transaction may be considered the acquisition of an asset, when substantially all of the fair value of assets acquired is concentrated in a single identifiable asset, rather than a business combination. Asset acquisitions are accounted for by allocating the cost of the acquisition to the individual assets acquired and liabilities assumed on a relative fair value basis. Acquisition related costs are capitalized as a component of the assets acquired.

Reporting Currency

(c) Reporting Currency

The consolidated financial statements are prepared in the reporting currency of U.S. Dollars. The functional currency of the vessel-owning Partnership subsidiaries is the U.S. Dollar, because the subsidiaries operate in the international shipping market, in which all revenues are U.S. Dollar-denominated and the majority of expenditures are made in U.S. Dollars. Transactions involving other currencies during the year are converted into U.S. Dollars using the exchange rates in effect at the time of the transactions. As of the balance sheet dates, monetary assets and liabilities that are denominated in currencies other than the U.S. Dollar are translated to reflect the year-end exchange rates. Resulting gains or losses are reflected separately in the accompanying consolidated statements of operations.

Use of Estimates

(d) Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives and impairment of Vessels, drydocking, purchase price allocation and income taxes.

Revenues and Operating Expenses

(e) Revenues and Operating Expenses

The Partnership recognizes revenues from time charters and bareboat charters as operating leases on a straight-line basis over the term of the charter, net of any commissions. Under time charters, revenue is not recognized during days the Vessel is off-hire. Revenue is recognized from delivery of the Vessel to the charterer, until the end of the contract period. Under time charters, the Partnership is responsible for providing the crewing and other services related to the Vessel's operations, the cost of which is included in the daily hire rate, except when off-hire. Under bareboat charters, the Partnership provides a specified Vessel for a fixed period of time at a specified day rate. Where the term of the contract is based on the duration of a single voyage, the partnership evaluates whether the voyage contain leases and if so recognize lease revenue as described above, and when not, recognizes revenue ASC 606 over time on a load-to-discharge basis.

Voyage expenses are all expenses unique to a particular voyage, including bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls and agency fees. Voyage expenses are paid by the customer under time charter and bareboat charters. Voyage expenses are paid by the Partnership for spot contracts and during periods of off-hire and are recognized when incurred.

Vessel operating expenses include crewing, repairs and maintenance, insurance, stores, lube oils and communication expenses. Vessel operating expenses are paid by the Partnership for time charters, spot contracts and during off-hire and are recognized when incurred.

As further discussed in Note 18—Related Party Transactions, related parties have provided the management services for the Vessels and employ the crews that work on the Vessels. The Partnership has no direct employees and, accordingly, is not liable for any pension or post-retirement benefits.

Financial Income (Expense)

(f) Financial Income (Expense)

Other finance expense includes external bank fees, commitment fees paid on undrawn revolving credit facility, financing service fees paid to related parties and guarantee commissions paid to external and related parties in connection with the Partnership’s debt and other bank services.

Cash and Cash Equivalents

(g) Cash and Cash Equivalents

The Partnership considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

Restricted Cash

(h) Restricted Cash

Restricted cash consists of bank deposits, which may only be used to settle principal payments under the Partnership’s Vessel financing arrangements.

Trade Accounts Receivable

(i) Trade Accounts Receivable

Accounts receivable are recorded at the invoiced amount and do not bear interest. Under terms of the current time charters and bareboat charters, the customers are committed to pay for the full month’s charter the first day of each month. See Note 2(s)—Prepaid Charter. The allowance for doubtful accounts is the Partnership’s best estimate of the amount of probable credit losses in existing accounts receivable. The Partnership establishes provisions for doubtful accounts on a case-by-case basis when it is unlikely that required payments of specific amounts will occur. In establishing these provisions, the Partnership considers the financial condition of the customer as well as specific circumstances related to the receivable. Receivable amounts determined to be unrecoverable are written-off. There were no allowances for doubtful accounts or amounts written off against the allowance for doubtful accounts as of December 31, 2018 and 2017. The Partnership does not have any off-balance-sheet credit exposure related to its customers.

Inventories

(j) Inventories

Inventories, which are comprised principally of lubricating oils, are stated at the lower of cost or net realizable value. For vessels on time charters or bareboat charters, there are no bunkers, as the charterer supplies the bunkers, which principally consist of fuel oil. Cost is determined using the first-in, first-out method for all inventories.

Other Current Assets

(k) Other Current Assets

Other current assets principally consist of prepaid expenses and other receivables.

Vessels and Equipment

(l) Vessels and Equipment

Vessels and equipment are stated at the historical acquisition or construction cost, including capitalized interest, supervision and technical and delivery cost, net of accumulated depreciation and impairment loss, if any. Expenditures for subsequent conversions and major improvements are capitalized, provided that such costs increase the earnings capacity or improve the efficiency or safety of the vessels.

Generally, the Partnership drydocks each vessel every 60 months until the vessel is 15 years old and every 30 months thereafter, as required for the renewal of certifications issued by classification societies. For vessels operating on time charters, the Partnership capitalizes the costs directly associated with the classification and regulatory requirements for inspection of the vessels and improvements incurred during drydocking. Drydock cost is depreciated on a straight-line basis over the period until the next planned drydocking takes place. The Partnership expenses costs related to routine repairs and maintenance performed during drydocking or as otherwise incurred. For vessels that are newly built or acquired, an element of the cost of the vessel is initially allocated to a drydock component and depreciated on a straight-line basis over the period until the next planned drydocking. When significant drydocking expenditures occur prior to the expiration of this period, the Partnership expenses the remaining balance of the original drydocking cost in the month of the subsequent drydocking. For vessels operating on bareboat charters, the charterparty bears the cost of any drydocking.

Depreciation on vessels and equipment is calculated on a straight-line basis over the asset’s estimated useful life, less an estimated residual value, as follows:

 

 

 

 

 

    

Useful Life

Hull

 

25 years

Anchor-handling, loading and unloading equipment

 

25 years

Main/auxiliary engine

 

25 years

Thruster, dynamic positioning systems, cranes and other equipment

 

25 years

Drydock costs

 

2.5 – 5 years

 

A Vessel is depreciated to its estimated residual value, which is calculated based on the weight of the ship and estimated steel price. Any cost related to the disposal is deducted from the residual value.

Capitalized Interest

(m) Capitalized Interest

Interest expense incurred on the Partnership’s debt during the construction of the Vessels exceeding one year is capitalized during the construction period.

Impairment of Long-Lived Assets

(n) Impairment of Long-Lived Assets

Vessels and equipment, vessels under construction and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Partnership first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

Goodwill and Intangibles

(o) Goodwill and Intangibles

The Partnership allocates the cost of acquired companies to the identifiable tangible and intangible assets and liabilities acquired, with the remaining amount being classified as goodwill. Goodwill is not amortized but is reviewed for impairment annually or more frequently if impairment indicators are identified.

The Partnership tests goodwill for impairment using a two-step analysis, with the option of performing a qualitative assessment before performing the first step of the two-step analysis, whereby the carrying value of the reporting unit is compared to its fair value in the first step. If the carrying value of the reporting unit is greater than its fair value, the second step is performed, where the implied fair value of goodwill is compared to its carrying value. An impairment charge is recognized for the amount by which the carrying amount of goodwill exceeds its fair value. The fair value is estimated using the net present value of discounted cash flows of the reporting unit. The Partnership has only one reporting unit.

Intangible assets represent contractual rights for charters obtained in connection with business and asset acquisitions that have favorable contractual terms relative to market as of the acquisition dates. Contract liabilities represent contractual rights obtained in connection with business acquisitions that have unfavorable contractual terms relative to market as of the acquisition dates. The favorable and unfavorable contract rights have definite lives and are amortized to revenues over the period of the related contracts. Intangible assets with a definite life are tested for impairment whenever events or circumstances indicate that their carrying amount may not be recoverable. An impairment loss is recognized if the carrying amount exceeds the estimated fair value of the asset.

The contract related intangible assets and liabilities and their amortization periods at acquisition dates are as follows:

 

 

 

 

Intangible category

    

Amortization Period

Above market time charter-Tordis Knutsen

 

4.8 years

Above market time charter-Vigdis Knutsen

 

4.9 years

Unfavorable contractual rights-Fortaleza Knutsen

 

12 years

Unfavorable contractual rights-Recife Knutsen

 

12 years

 

The intangible for the above market value of the time charter contract associated with the Tordis Knutsen is amortized to time charter revenue on a straight line basis over the remaining term of the contract of approximately 4.8 years as of the acquisition date. The intangible for the above market value of the time charter contract associated with the Vigdis Knutsen is amortized to time charter revenue on a straight line basis over the remaining term of the contract of approximately 4.9 years as of the acquisition date.

The unfavorable contractual rights for charters associated with Foraleza Knutsen and Recife Knutsen were obtained in connection with a step acquisition in 2008 that had unfavorable contractual terms relative to market as of acquisition date. The Fortaleza Knutsen and the Recife Knutsen commenced on their 12 years’ fixed bareboat charters in March 2011 and August 2011, respectively. The unfavorable contract rights related to Fortaleza Knutsen and Recife Knutsen are amortized to bareboat revenues on a straight line basis over the 12 years’ contract period that expires in March 2023 and August 2023, respectively.

Debt Issuance Costs

(p) Debt Issuance Costs

Debt issuance costs, including fees, commissions and legal expenses, are deferred and presented net of debt. Debt issuance costs of term loans are amortized over the term of the relevant loan. Amortization of debt issuance costs is included in interest expense. These costs are presented as a deduction from the corresponding liability, consistent with debt discount.

Derivative Instruments

(q) Derivative Instruments

The Partnership uses derivatives to reduce market risks associated with its operations. The Partnership uses interest rate swaps for the management of interest risk exposure. The interest rate swaps effectively convert a portion of the Partnership’s debt from a floating to a fixed rate over the life of the transactions without an exchange of underlying principal.

The Partnership seeks to reduce its exposure to fluctuations in foreign exchange rates through the use of foreign currency forward contracts.

All derivative instruments are initially recorded at fair value as either assets or liabilities in the accompanying consolidated balance sheets and subsequently measured to fair value. The Partnership does not apply hedge accounting to its derivative instruments. Changes in the fair value of the derivative instruments are recognized in earnings. Gains and losses from the interest rate swap contracts of the Partnership related to long-term mortgage debt and foreign exchange forward contracts are recorded in realized and unrealized gain (loss) on derivative instruments in the consolidated statements of operations. Cash flows related to interest rate swap contracts are presented as cash flows provided by operating activities. Cash flows related to foreign exchange forward contracts entered into to economically hedge operating expenses in currencies other than U.S. Dollars are presented as cash flows provided by operating activities in the consolidated statements of cash flows, while cash flows related to foreign exchange forward contracts entered into to hedge contractual obligations to pay the shipyard in currencies other than functional currency of U.S. Dollars are presented as cash flows used in investing activities in the consolidated statements of cash flows.

Income Taxes

(r) Income Taxes

Historically, part of the Partnership’s activities were subject to ordinary taxation and taxes were paid on taxable income (including operating income and net financial income and expense), while part of the activities were subject to the Norwegian Tonnage Tax Regime (the “tonnage tax regime”). Under the tonnage tax regime, the tax is based on the tonnage of the vessel, and operating income is tax free. The net financial income and expense remains taxable as ordinary income tax for entities subject to the tonnage tax regime. Income taxes arising from the part of activities subject to ordinary taxation are included in income tax expense in the consolidated statements of operations. For the portion of activities subject to the tonnage tax regime, tonnage taxes are classified as vessel operating expenses while the current and deferred taxes arising on net financial income and expense are reflected as income tax expense in the consolidated statements of operations. The amounts of tonnage tax included in operating expenses for the years ended December 31, 2018, 2017 and 2016 were $0.3 million, $0.2 million and $0.2 million, respectively.

The Partnership accounts for deferred income taxes using the liability method. Under the liability method, deferred tax assets and liabilities are recognized for the anticipated future tax effects of temporary differences between the financial statement basis and the tax basis of the Partnership’s assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. A valuation allowance for deferred tax assets is recorded when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized.

Recognition of uncertain tax positions is dependent upon whether it is more-likely-than-not that a tax position taken or expected to be taken in a tax return will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. If a tax position meets the more-likely-than-not recognition threshold, it is measured to determine the amount of benefit to recognize in the financial statements based on U.S. GAAP guidance. The Partnership recognizes interest and penalties related to uncertain tax positions in income tax expense.

Prepaid Charter

(s) Prepaid Charter

Under terms of the time charters and bareboat charters, the customer pays for the month’s charter the first day of each month that is recorded as prepaid charter revenues.

Commitments, Contingencies and Insurance Proceeds

(t) Commitments, Contingencies and Insurance Proceeds

Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. See Note 19—Commitments and Contingencies.

Insurance claims for property damage for recoveries up to the amount of loss recognized are recorded when the claims submitted to insurance carriers are probable of recovery. Claims for property damage in excess of the loss recognized and for loss of hire are considered gain contingencies, which are generally recognized when the proceeds are received.

Fair Value Measurements

(u) Fair Value Measurements

The Partnership utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Partnership determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

·

Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

·

Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

·

Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

Recently Adopted Accounting Standards and New Accounting Standards Not Yet Adopted

(v) Recently Adopted Accounting Standards

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606), as subsequently updated by the FASB, which provides new authoritative guidance on the methods of revenue recognition and related disclosure requirements. This new standard supersedes existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. This update creates a five-step model and requires a company to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligation in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue as each performance obligation is satisfied. Under the new standard, additional qualitative and quantitative disclosures are required. Effective January 1, 2018, the Partnership adopted the requirements of ASC 606 to new and existing contracts not yet completed as of January 1, 2018, using the modified retrospective approach where the cumulative effect of initially applying the standard is recorded as an adjustment to the opening balance of equity. The Partnership made an assessment on the various implementation aspects of ASU 2014-09 and its amendments, and since there are no changes to the timing or amount of revenue recognized, the Partnership has concluded that the effect of the implementation of this new standard will cause no material cumulative effect to the Partnership’s historical or future financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Partnership adopted this ASU prospectively from January 1, 2018. As a result, this increases the likelihood that future dropdowns of Vessels may be considered the acquisition of an asset rather than a business combination.

On March 1, 2018, the partnership’s wholly owned subsidiary, KNOT Shuttle tankers AS, acquired KNOT’s 100% interest in KNOT Shuttle Tankers 30 AS (“KNOT 30”), the company that owns and operates the Anna Knutsen. Following the adoption of ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, the Partnership accounted for this acquisition as an acquisition of an asset. The cost of the group of assets acquired in the asset acquisition has been allocated to the individual assets acquired or liabilities assumed based on their relative fair values. See the Note 21—Acquisitions.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. The new guidance clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The Partnership adopted this ASU on January 1, 2018. The Partnership's adoption of this standard did not have a material impact on the Partnership's consolidated statement of cash flows or related disclosures.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash, which requires that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts presented on the statement of cash flows. The standard eliminates the presentation of transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. Additional disclosures are required for the nature of the restricted cash and restricted cash equivalents. The Partnership adopted this ASU on January 1, 2018 under a retrospective approach. The Partnership's adoption of this standard did not have a material impact on the Partnership's consolidated statement of cash flows or related disclosures.

There are no other recent accounting pronouncements, whose adoption had a material impact on the consolidated financial statements in the current year.

(w) New Accounting Standards Not Yet Adopted

In February 2016, the FASB issued ASU 2016-02, Leases (ASC 842). The objective is to establish the principles that lessors and lessees shall apply to report useful information to users of financial statements about the amount, timing and uncertainty of cash flows arising from a lease. The Partnership is the lessor for its Vessels that operate on time charters and bareboat charters. Accounting by a lessor is largely unchanged from the previous standard. The Partnership does not have any material leased assets. A lessee will be required to recognize in its balance sheet a lease liability to make lease payments and a right-of-use asset. The standard requires a modified retrospective transition method for all entities and the standard provides for optional practical expedients in implementing the standard under the modified retrospective approach.

In July 2018, the FASB issued targeted improvements to the leasing guidance allowing for an additional optional transition method that allow entities to initially apply the new lease standard and its disclosures at the transition date and recognize a cumulative-effect adjustment to the opening balance of retained earnings. The Partnership has elected to use this optional transition approach. The standard is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. The Partnership will adopt ASC 842 and implement the revised guidance as of January 1, 2019. The Partnership will apply the package of practical expedients, but not the hindsight practical expedients since the use of hindsight practical expedient only impacts lease classification if the package of practical expedients is not elected. The Partnership will not reassess whether any expired or existing contracts are, or contain leases, will not reassess lease classification, and will not reassess initial direct costs for any existing leases. Additionally, the practical expedient of disregarding short-term leases for agreements with lease terms of 12 months or less as a lessee and the expedient of not separating lease components from non-lease components will be used for all classes of underlying assets in the Partnership. Based upon assessments performed to date, the Partnership does not expect material effects on the accounting for existing leases applied in the consolidated financial statements where the Partnership is the lessor. Under ASU 2016-02, the Partnership will recognize a right-of-use asset and a lease liability on the balance sheet for certain leases where the Partnership is the lessee based on the present value of future minimum lease payments, whereas currently no right-of-use asset or lease liability is recognized. Based on the analysis performed by the Partnership to date, the right of use asset and lease liability to be recognized on January 1, 2019 is expected not to be material.

(1)

Guarantee income from KNOT:  Pursuant to the Omnibus Agreement, KNOT agreed to guarantee the payments of the hire rate under the initial charter of the Bodil Knutsen and Windsor Knutsen for a period of five years from the closing date of the IPO (until April 15, 2018). In October 2015, the Windsor Knutsen commenced on a new Shell time charter with a hire rate below the hire rate in the initial charter. The difference between the new hire rate and the initial rate was paid by KNOT until April 15, 2018. The Vigdis Knutsen suffered damages to its hull in connection with a ship-to-ship loading on May 24, 2017 and the vessel went off-hire 6 days in June 2017 due to repairs of the damage. In connection with the Vigdis Knutsen acquisition, KNOT agreed to pay for the repair cost and charter hire lost in connection with the incident. The reimbursement from KNOT for lost charter hire is accounted for as guarantee income. See Note 18(b)—Related Party Transactions—Guarantees and Indemnifications.

(2)

Technical and operational management fee from KNOT Management or KNOT Management Denmark to Vessels: KNOT Management or KNOT Management Denmark provides technical and operational management of the vessels on time charter including crewing, purchasing, maintenance and other operational service. In addition, there is also a charge for 24‑hour emergency response services provided by KNOT Management for all vessels managed by KNOT Management.

(3)

Administration fee from KNOT Management and Knutsen OAS Shipping AS (“KOAS”) and Knutsen OAS (UK) Ltd. (“KOAS UK”): Administration costs include the compensation and benefits of KNOT Management’s management and administrative staff as well as other general and administration expenses. Some benefits are also provided by KOAS and KOAS UK. Net administration costs are total administration cost plus a 5% margin, reduced for the total fees for services delivered by the administration staffs and the estimated shareholder costs for KNOT that have not been allocated. As such, the level of net administration costs as a basis for the allocation can vary from year to year based on the administration and financing services offered by KNOT to all the vessels in its fleet each year. KNOT Management also charges each subsidiary a fixed annual fee for the preparation of the statutory financial statement.

(4)

Administration and management fee from KNOT Management and KNOT Management Denmark: For bareboat charters, the shipowner is not responsible for providing crewing or other operational services and the customer is responsible for all vessel operating expenses and voyage expenses. However, each of the vessels under bareboat charters is subject to a management and administration agreement with either KNOT Management or KNOT Management Denmark, pursuant to which these companies provide general monitoring services for the vessels in exchange for an annual fee.

(5)

Interest expense charged from KNOT: KNOT invoiced interest (expense) income for any outstanding payables to (receivable from) owners and affiliates to the vessel-owning subsidiaries.
