FORWARD-LOOKING STATEMENTS

Statements in this Quarterly Report on Form 10-Q (“Form 10-Q”) or in documents incorporated by reference that are not historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include statements about (i) our ability to meet our investment objectives and to manage and mitigate market risk with respect to our investments; (ii) the adequacy of our reinsurance program and our ability to diversify risk and safeguard our financial position; (iii) our estimates with respect to tax and accounting matters including the impact on our financial statements; (iv) future dividends, if any; (v) our expectations related to our financing activities; (vi) the sufficiency of our liquidity to pay our insurance company affiliates’ claims and expenses, as well as to satisfy commitments in the event of unforeseen events; (vii) the sufficiency of our capital resources, together with cash provided from our operations, to meet currently anticipated working capital requirements; (viii) the potential effects of the seasonality of our business, including effects on our reinsurance business and financial results; (ix) our intentions with respect to our credit risk investments; and (x) the potential effects of our current legal proceedings.

These statements are based on current expectations, estimates and projections about the industry and market in which we operate, and management’s beliefs and assumptions. Without limiting the generality of the foregoing, words such as “may,” “will,” “expect,” “believe,” “anticipate,” “intend,” “could,” “would,” “estimate,” or “continue” or the negative variations thereof or comparable terminology are intended to identify forward-looking statements. Forward-looking statements are not guarantees of future performance and involve certain known and unknown risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. The risks and uncertainties include, without limitation:

•

the possibility that actual losses may exceed reserves;

•

the concentration of our business in coastal states, which could be impacted by hurricane losses or other significant weather-related events such as northeastern winter storms;

•

our exposure to catastrophic weather events;

•

the fluctuation in our results of operations;

•

increased costs of reinsurance, non-availability of reinsurance, and non-collectability of reinsurance;

•

our failure to identify suitable acquisition candidates; effectively manage our growth and integrate acquired companies;

•

increased competition, competitive pressures, and market conditions;

•

our failure to accurately price the risks we underwrite;

•

inherent uncertainty of our models and our reliance on such models as a tool to evaluate risk;

•

the failure of our claims department to effectively manage or remediate claims;

•

low renewal rates and failure of such renewals to meet our expectations;

•

our failure to execute our diversification strategy;

•

failure of our information technology systems and unsuccessful development and implementation of new technologies;

•

a lack of redundancy in our operations;

•

our failure to attract and retain qualified employees and independent agents or our loss of key personnel;

•

our inability to generate investment income;

•

our inability to maintain our financial stability rating;

•

effects of emerging claim and coverage issues relating to legal, judicial, environmental and social conditions;

•

the failure of our risk mitigation strategies or loss limitation methods;

•

our reliance on independent agents to write voluntary insurance policies;

•

changes in regulations and our failure to meet increased regulatory requirements;

•

our ability to maintain effective internal controls over financial reporting;

•

our status as an “emerging growth company”;

•

the regulation of our insurance operations; and

•

certain characteristics of our common stock.

Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or operating results.

These forward-looking statements are subject to numerous risks, uncertainties and assumptions about us described in our filings with the Securities and Exchange Commission (the “SEC”). The forward-looking statements we make in our Form 10-Q are valid only as of the date of our Form 10-Q and may not occur in light of the risks, uncertainties and assumptions that we describe from time to time in our filings with the SEC. A detailed discussion of these and other risks and uncertainties that could cause actual results and events to differ materially from our forward-looking statements is included in the section entitled “Risk Factors” in Part I, Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2018. Except as required by applicable law, we undertake no obligation and disclaim any obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

In the opinion of the Company’s management, all material intercompany transactions and balances have been eliminated and all adjustments consisting of normal recurring accruals which are necessary for a fair statement of the financial condition and results of operations for the interim periods have been reflected. The accompanying interim condensed consolidated financial statements and related footnotes should be read in conjunction with the Company’s audited consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 Form 10-K”).

Significant accounting policies

The Accounting policies of the Company are set forth in Note 1 to Condensed Consolidated Financial Statements contained in the Company’s 2018 Annual Report on Form 10-K. We include herein certain updates to those policies.

Leases

At the inception of a contract, we assess whether the contract is, or contains, a lease. The assessment is based on (1) whether the contract involves the use of distinct identified assets, (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether the Company has the right to direct the use of the asset.

All significant lease arrangements are generally recognized at lease commencement. A right of use (“ROU”) asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (short term leases) and we recognize lease expense for these leases as incurred over the lease term.

ROU assets represent our right to use an underlying asset during the reasonably certain lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise the option.

Operating lease ROU assets and liabilities are recognized based on the present value of lease payments not yet paid. Lease payments may be fixed or variable, however, only fixed payments or in-substance fixed payments are included in determining the lease liability. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the term of the lease. We have lease agreements with lease and non-lease components, which are generally accounted for separately.

We primarily use our incremental borrowing rates for our operating leases (rates are not readily determinable) and implicit rates for our financing leases in determining the present value of lease payments.

In the first quarter of 2019, the Company adopted ASU 2016 -02 and did not recognize an opening adjustment to retained earnings as a result of the adoption of FASB 842. Refer to Note 5-Leases herein for further information.

Reclassification

Certain prior year amounts have been reclassified to conform to the current year presentation.

Recently Adopted Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) Lease Accounting, which requires that a lessee recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. As with previous guidance, there continues to be a differentiation between finance leases and operating leases, however this distinction now primarily relates to differences in the manner of expense recognition over time and in the classification of lease payments in the statement of cash flows. Lease assets and liabilities arising from both finance and operating leases will be recognized in the statement of financial position. ASU 2016-02 leaves the accounting for leases by lessors largely unchanged from previous GAAP.

We adopted the guidance prospectively during the first quarter of 2019. As part of our adoption, we elected not to reassess historical lease classification or recognize short-term leases on our balance sheet. At implementation, we recorded approximately $2.8 million as right-of-use operating and financing leased assets in other assets and approximately $2.8 million of lease liabilities in accounts payable and other liabilities. We did not recognize an opening adjustment to retained earnings. Adoption of this standard did not materially impact the Company’s Condensed Consolidated Statements of Operations and Other Comprehensive Income and Statements of Cash Flows. See Note 5 to the condensed consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which provided certain improvements to ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01) and ASU 2016-13.

FASB ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, introduces new guidance for the accounting for credit losses on financial instruments in with its scope. The new guidance provides for recognition of expected credit losses on certain types of financial instruments. This ASU requires immediate recognition of management estimates of current expected credit losses (“CECL”) and will apply to: (1) financial assets subject to credit losses which are currently measured at amortized costs; and (2) certain off-balance sheet credit exposures. This includes loans, held-to-maturity and/or available for sale debt securities, loan commitments, financial guarantees, and net investments in leases, as well as reinsurance and trade receivables. The measurement of credit losses for available-for-sale debt securities measured at fair value is not affected except that credit losses recognized are limited to the amount by which fair value is below amortized cost and carrying value adjustment is recognized through a valuation allowance which may change over time but once recorded cannot subsequently be reduced to an amount below zero. The ASU 2016-13 is effective for public entities for interim and annual periods beginning after December 15, 2019, and for most affected instruments must be adopted using a modified retrospective approach, with a cumulative effect adjustment recorded to the beginning retained earnings balance.

The Company’s implementation activities, which remain in process, include the development of models, methodologies, data input and assumptions to be used in estimating expected credit losses. The implementation primarily impacts the Company’s debt securities and reinsurance recoverable balances. The adoption of this standard is not expected to be material to our financial position, results of operations or cash flows.

For information regarding other accounting standards that the Company has not yet adopted, refer to our Annual Report on Form 10-K, filed on March 12, 2019, the section of Note 1 of the notes to the consolidated financial statements entitled the “Accounting Pronouncement Not Yet Adopted”.

U.S. government and agency securities include pledged fixed maturity securities with an estimated fair value of $24.5 million and $31.0 million under the terms and condition of the advance agreement entered into with a financial institution as of September 30, 2019 and December 31, 2018, respectively. The Company is permitted to withdraw or exchange any portion of the pledged collateral over the minimum requirement at any time.

The Company calculates the gain or loss realized on the sale of investments by comparing the sales price (fair value) to the cost or adjusted/amortized cost of the security sold. The Company determines the cost or adjusted/amortized cost of the security sold using the specific-identification method. The following tables detail the Company’s net realized gains (losses) by major investment category for the three and nine months ended September 30, 2019 and 2018.

Gains (losses) on equity investments consists of realized and unrealized holding gains or losses on marketable equity investments and fair value adjustment, including, if any, impairments on nonmarketable equity investments. For the three and nine months ended September 30, 2018, the Company reclassed $128,000 and $927,000 from changes in the fair value of equity investments from Other revenue to Net realized and unrealized gains (losses) to conform to current presentation, respectively.

For the three months ended September 30, 2019 the Company sold no equity securities nor did it hold any marketable equity securities as of that date. For the three months ended September 30, 2018, the Company received proceeds from the sale of marketable equity securities of approximately $428,000. The Company recorded a gross gain of $7,900 and a gross loss from these sales of approximately $14,700.

For the nine months ended September 30, 2019 and 2018, the Company received proceeds from the sale of its holdings in marketable equity securities of approximately $26.5 million and $4.2 million. These sales resulted in a gross gain of $2.4 million and a gross loss of $1.2 million respectively, and a gross gain of approximately $1,100 and a gross loss of $184,500, respectively, related primarily to unrealized holding gains or losses in certain marketable equity securities.

For the nine months ended September 30, 2019, the Company had unrealized net holding gains of $993,600 recognized on nonmarketable other investments still held at September 30, 2019.

The table below summarizes the Company’s fixed maturity securities at September 30, 2019 by contractual maturity periods. Actual results may differ as issuers may have the right to call or prepay obligations, with or without penalties, prior to the contractual maturity of those obligations.

The Company is required to maintain assets on deposit with various regulatory authorities or in trust accounts to support its insurance and reinsurance operations.

As of September 30, 2019, the Company evaluated its fixed maturity securities for impairment and determined that none of its investments in fixed maturity securities that reflected an unrealized loss position were other-than-temporarily impaired. The issuers of the fixed maturity securities in which the Company invests continue to make interest payments on a timely basis and have not suffered any credit rating reductions. The Company does not intend to sell, nor is it likely that it would be required to sell, the fixed maturity securities before the Company recovers its amortized cost basis.

Limited Partnerships, REIT’s and Limited Liability Company Investments

The Company has interests in limited partnerships (“LPs”) that are not registered or readily tradable on a securities exchange. The investments are private equity funds managed by general partners who make financial policy and operational decisions. The Company is not the primary beneficiary and does not consolidate these partnerships. As of September 30, 2019, the estimated fair value of our investments in the LPs interests was $21.0 million. The general partner's objective is to achieve capital appreciation through investments in marketable securities and broad markets, preferred stock, industry-focused and fixed income exchange-traded funds (ETFs).

These funds are carried at net asset value, which approximates fair value with changes in fair value recorded in net realized gains (losses) on the Company’s condensed consolidated statement of income and comprehensive income. Realized gains (losses) on sales of these investments are reported within net realized and unrealized gains (losses) on the Company’s condensed consolidated statement of income and comprehensive income .

The Company has an interest in limited liability companies (“LLCs”) that are not registered or readily tradable on a securities exchange. The investments are in LLCs that maintains a specific ownership account for each investor, similar to a partnership capital account structure, and are viewed as similar to an investment in a LP for purposes of determining whether a noncontrolling investment in an LLC shall be accounted for using the cost method or the equity method. The Company receives monthly returns of capital from the LLCs which reduces the fair value of the Company’s investments. As of September 30, 2019, the estimated fair value of the Company’s investments in the LLCs was $6.4 million. The interest expenses from these funds are recorded to net investment income.

For the nine months ended September 30, 2019, the Company invested $24.9 million in LPs and LLCs. For the comparable period of 2018, the Company did not make acquisition of this category of assets. For the nine month period ended September 30, 2019, the Company recognized net investment gains in LPs in aggregate of $1.0 million. As of the third quarter of 2019 and 2018, the Company received cash distributions, net of allocations from its LLC investments of approximately $272,000 and $94,000, respectively, representing return of capital on its investments. The Company incurred approximately $565,000 of allocated costs during the third quarter of 2019 and $1,300 for the comparable period of 2018.

NOTE 3. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company performs fair value measurements in accordance with FASB Accounting Standards Codification (ASC) 820, Fair Value Measurement. ASC 820 defines fair values as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at the fair values, the Company considers the principal or most advantageous market in which it would transact and consider assumptions that market participants would use when pricing the asset or liabilities, such as inherent risk transfer restrictions and risk of nonperformance. ASC 820 establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset’s or liability’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

For the Company’s investments in U.S. government securities that do not have prices in active markets, agency securities, state and municipal governments, and corporate bonds, the Company obtains the fair values from its third-party valuation service and evaluates the relevant inputs, assumptions, methodologies and conclusions associated with such valuations. The valuation service calculates prices for the Company’s investments in the aforementioned security types on a month-end basis by using several matrix-pricing methodologies that incorporate inputs from various sources. The model the valuation service uses to price U.S. government securities and securities of states and municipalities incorporates inputs from active market makers and inter-dealer brokers. To price corporate bonds and agency securities, the valuation service calculates non-call yield spreads on all issuers, uses option-adjusted yield spreads to account for any early redemption features, then adds final spreads to the U.S. Treasury curve as of quarter end. The inputs the valuation service uses in their calculations are not quoted prices in active markets, but are observable inputs, and therefore represent Level 2 inputs.

As of September 30, 2019, and December 31, 2018, there were no transfers in or out of Level 1, 2, and 3.

Investments excluded from the fair value hierarchy

The Company also invests in real estate investment trusts (“REIT”), private LPs and LLCs. This investment categorization has the potential for higher returns but also the potential for higher degrees of risk, including less than stable rates of returns and may provide less liquidity. Fair value estimates of the LPs and LLCs are based on their net asset values, as reported by the manager of the LP or LLC. The fair value of these investments is measured at net asset value and is excluded from the fair value hierarchy. For the current LPs, the Company may, as of the last day of each calendar quarter, upon at least 65 days’ prior written notice, withdraw all or any portion of the balance in its investment. There is a 3% withdrawal fee if made during the first year of investment that expires in February 2020.

Non-recurring fair value measurements

Assets and liabilities that are measured at fair value on a non-recurring basis include intangible assets and goodwill which are recognized at fair value during the period in which an acquisition is completed, from updated estimates and assumptions during the measurement period, or when they are considered to be impaired. These non-recurring fair value measurements, primarily for intangible assets acquired, were based on Level 3 unobservable inputs. For the quarters ended September 30, 2019 and 2018, these non-recurring fair values inputs consisted of brand, agent relationships, renewal rights, customer relations, trade names, non-compete and goodwill. To evaluate such assets for a potential impairment, we determine the fair value of the goodwill and intangible assets using a combination of a discounted cash flow approach and market approaches, which contain significant unobservable inputs and therefore are considered a Level 3 fair value measurement. The unobservable inputs in the analysis generally include future cash flow projections and a discount rate.

There were no non-recurring fair value adjustments to intangible assets and goodwill during the third quarters of 2019 and 2018. We record any measurement period adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill.

NOTE 4. OTHER COMPREHENSIVE INCOME

Other comprehensive income (loss) was $15.1 million and $(6.4) million for the nine months ended September 30, 2019 and 2018, respectively. The difference between net income as reported and comprehensive income was due to the changes in unrealized gains and losses, net of taxes on fixed maturities securities.

NOTE 5. LEASES

The Company has entered into operating and financing leases primarily for real estate and vehicles. The Company will determine whether an arrangement is a lease at inception of the agreement. The operating leases have terms of one to ten years, and often include one or more options to renew. These renewal terms can extend the lease term from two to ten years, and are included in the lease term when it is reasonably certain that the Company will exercise the option. The Company considers these options in determining the lease term used in establishing our right-of-use assets and lease obligations. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Because the rate implicit in each operating lease is not readily determinable, the Company uses its incremental borrowing rate to determine present value of the lease payments. The Company used the implicit rates within the finance leases.

Components of our lease costs for the three and nine months ended September 30, 2019 are as follows (in thousands):

	Three Months Ended September 30, 2019		Nine Months Ended September 30, 2019
Amortization of ROU assets - Finance leases	$	19	$	58

NOTE 11. INCOME TAXES

For the three months ended September 30, 2019 and 2018, the Company recorded $3.0 million and $3.0 million, respectively, of income tax expenses which corresponds to effective tax rates of 26.6% and 33.4%, respectively. Lower pre-tax income for the prior year quarter had an adverse impact on the effective tax rate due to the impact of permanent tax differences. During the nine months ended September 30, 2019 and 2018, the Company recorded $5.7 million and $9.1 million, respectively, of income tax expense which corresponds to an estimated annual effective tax rate of 26.4% and 28.1%, respectively. Effective tax rates are dependent upon components of pre-tax earnings and the related tax effects. The effective tax rate can fluctuate throughout the year as estimates used in the tax provision are updated as more information becomes available.

At September 30, 2019 and December 31, 2018, we had no significant uncertain tax positions or unrecognized tax benefits that, if recognized, would impact the effective income tax rate.

NOTE 12. REINSURANCE

Overview

The Company’s reinsurance program is designed, utilizing the Company’s risk management methodology, to address its exposure to catastrophes or large non-catastrophic losses. The Company’s program provides reinsurance protection for catastrophes including hurricanes, tropical storms, tornadoes and winter storms. The Company’s reinsurance agreements are part of its catastrophe management strategy, which is intended to provide its stockholders an acceptable return on the risks assumed in its property business, and to reduce variability of earnings, while providing protection to the Company’s policyholders.

In order to limit our potential exposure to catastrophic events, we purchase significant reinsurance from third party reinsurers and sponsor catastrophe bonds issued by Citrus Re Ltd. The catastrophe reinsurance may be on an excess of loss or quota share basis. We also purchase reinsurance for non-catastrophe losses on a quota share, per risk or facultative basis. Purchasing a sufficient amount of reinsurance to consider catastrophic losses from single or multiple events or significant non-catastrophe losses is an important part of our risk strategy, and premiums paid (or ceded) to reinsurers is one of our largest cost components. Reinsurance involves transferring, or “ceding”, a portion of the risk exposure on policies we write to another insurer, known as a reinsurer. To the extent that our reinsurers are unable to meet the obligations they assume under our reinsurance agreements, we remain liable for the entire insured loss.

Our reinsurance agreements are prospective contracts. We record an asset, prepaid reinsurance premiums, and a liability, reinsurance payable, for the entire contract amount upon commencement of our new reinsurance agreements. We generally amortize our catastrophe reinsurance premiums over the 12-month contract period on a straight-line basis, which is June 1 through May 31. Our quota share reinsurance is amortized over the 12-month contract period and may be purchased on a calendar or fiscal year basis.

In the event that we incur losses and loss adjustment expenses recoverable under our reinsurance program, we record amounts recoverable from our reinsurers on paid losses plus an estimate of amounts recoverable on unpaid losses. The estimate of amounts recoverable on unpaid losses is a function of our liability for unpaid losses associated with the reinsured policies; therefore, the amount changes in conjunction with any changes to our estimate of unpaid losses. As a result, a reasonable possibility exists that an estimated recovery may change significantly in the near term from the amounts included in our condensed consolidated financial statements.

Our insurance regulators require all insurance companies, like us, to have a certain amount of capital and reinsurance coverage in order to cover losses and loss adjustment expenses upon the occurrence of a catastrophic event. Our reinsurance program provides reinsurance in excess of our state regulator requirements, which are based on the probable maximum loss that we would incur from an individual catastrophic event estimated to occur once in every 100 years based on our portfolio of insured risks. The nature, severity and location of the event giving rise to such a probable maximum loss differs for each insurer depending on the insurer’s portfolio of insured risks, including, among other things, the geographic concentration of insured value within such portfolio. As a result, a particular catastrophic event could be a one-in-100-year loss event for one insurance company while having a greater or lesser probability of occurrence for another insurance company. We also purchase reinsurance coverage to protect against the potential for multiple catastrophic events occurring in the same year. We share portions of our reinsurance program coverage among our insurance company affiliates.

Significant Reinsurance Contracts

2019-2020 Excess of Loss Reinsurance Programs

Catastrophe Excess of Loss Reinsurance

Effective June 1, 2019, we entered into catastrophe excess of loss reinsurance agreements covering Heritage Property & Casualty Insurance Company (“Heritage P&C”), Zephyr Insurance Company (“Zephyr”) and Narragansett Bay Insurance Company (“NBIC”). The catastrophe reinsurance programs are allocated amongst traditional reinsurers, catastrophe bonds issued by Citrus Re Ltd., a Bermuda special purpose insurer formed in 2014 (“Citrus Re”), the Florida Hurricane Catastrophe Fund (“FHCF”) and Osprey Re Ltd, our captive reinsurer. The FHCF covers Florida risks only and we participate at 90%. Our third-party reinsurers are either rated “A-” or higher by A.M. Best or S&P or are fully collateralized, to reduce credit risk.

The reinsurance program, which is segmented into layers of coverage, protects the Company for excess property catastrophe losses and loss adjustment expenses. The 2019-2020 reinsurance program provides first event coverage up to $1.5 billion for Heritage P&C, first event coverage up to $708.0 million for Zephyr, and first event coverage up to $936.0 million for NBIC. Our first event retention for each insurance company subsidiary follows: Heritage P&C - $20.0 million; Zephyr - $20.0 million; NBIC – $13.8 million.

Our program was placed on a cascading basis which provides greater horizontal protection in a multiple small events scenario and features additional coverage enhancements. This coverage exceeds the requirements established by the ratings agency of our insurance company affiliates, Demotech, Inc., the Florida Office of Insurance Regulation, the Hawaii Insurance Division, and the Rhode Island Department of Business Regulation.

We are responsible for all losses and loss adjustment expenses in excess of our reinsurance program. For second or subsequent catastrophic events, our total available coverage depends on the magnitude of the first event, as we may have coverage remaining from layers that were not previously fully exhausted. An aggregate of $2.6 billion of limit purchased in 2019 includes reinstatement through the purchase of reinstatement premium protection. In total, we have purchased $2.6 billion of potential reinsurance coverage, including our retention, for multiple catastrophic events. Our ability to access this coverage, however, will be subject to the severity and frequency of such events.

The Company's estimated net cost for the 2019-2020 catastrophe reinsurance programs is approximately $249.2 million.

Gross Quota Share Reinsurance

NBIC did not enter into a gross quota share reinsurance program for its fiscal year beginning June 1, 2019. For its previous fiscal year, NBIC purchased an 8% gross quota share reinsurance treaty effective June 1, 2018 which provided ground up loss recoveries of up to $1.0 billion.

Net Quota Share Reinsurance

NBIC’s Net Quota Share coverage is proportional reinsurance for which certain of our other reinsurance inures to the quota share (property catastrophe excess of loss and reinstatement premium protection and the second layer of the general excess of loss). An occurrence limit of $20.0 million for catastrophe losses is in effect on the quota share, subject to certain aggregate loss limits that vary by reinsurer. The amount and rate of reinsurance commissions slide, within a prescribed minimum and maximum, depending on loss performance. The Net Quota Share program was renewed on December 31, 2018 ceding 52% of the net premiums and losses and 10% of the prior year quota share will run off.

Aggregate Coverage

A $931.0 million of limit is structured on an aggregate basis (Top and Aggregate, Layer 1, Layer 2, Layer 3, Layer 4, Layer 5, Stub layers, Multi-Zonal and 2017-1 Notes). To the extent that this coverage is not fully exhausted in the first catastrophic event, it provides coverage commencing at its reduced retention for second and subsequent events where underlying coverage has been previously exhausted. The Company purchased reinstatement premium protection for $627.0 million of this coverage, which can be reinstated one time. Layers (with exception to FHCF) are “net” of a $40.0 million attachment point. Layers inure to the subsequent layers if the aggregate limit of the preceding layer(s) is exhausted, and the subsequent layer cascades down in its place.

NBIC placed 40% of an aggregate contract, which covers all catastrophe losses excluding named storms, on December 31, 2018, expiring May 31, 2019. The limit on the contract is $20.0 million, with a retention of $20.0 million and franchise deductible of $1.0 million.

NBIC placed 100% of an occurrence contract, which covers all catastrophe losses excluding named storms, on December 31, 2018, expiring December 31, 2019. The limit on the contract is $20.0 million with a retention of $20.0 million and has one reinstatement available.

Per Risk Coverage

For southeast losses and northeast commercial residential losses, excluding losses from named storms, the Company purchased property per risk coverage for losses and loss adjustment expenses in excess of $1.0 million per claim. The limit recovered for an individual loss is $9.0 million and total limit for all losses is $27.0 million. There are two reinstatements available with additional premium due based on the amount of the layer exhausted. For Northeast commercial residential losses only, the Company purchased property per risk coverage for losses and loss adjustments expenses in excess of $750,000 per claim. The limit recovered for an individual loss is $250,000 and total limit for all losses is $750,000. There are two reinstatements available with additional premium due based on the amount of the layer exhausted.

In addition, the Company purchased facultative reinsurance for losses in excess of $10.0 million for any properties it insured where the total insured value exceeded $10.0 million. This coverage applies to Southeast losses and Northeast commercial residential losses, excluding losses from named storms.

General Excess of Loss

NBIC’s general excess of loss reinsurance protects NBIC from single risk losses, both property and casualty. The casualty coverage provided by this reinsurance contract also responds on a “Clash” basis, meaning that multiple policies involved in a single loss occurrence can be aggregated into one loss and applied to the reinsurance contract. The coverage is in two layers in excess of NBIC’s retention of the first $400,000 of loss. The first layer is $350,000 excess $400,000 and the second layer is $2.75 million excess $750,000 (Casualty second layer is $1.25 million excess $750,000). Both layers are 100% placed.

Semi-Automatic Facultative Excess of Loss

NBIC’s automatic property facultative reinsurance protects NBIC from single risk losses, for property risks with a total insured value excess of $3.5 million subject to a limit.

2018 – 2019 Reinsurance Program

Catastrophe Excess of Loss Reinsurance

Effective June 1, 2018, we entered into catastrophe excess of loss reinsurance agreements covering Heritage P&C, Zephyr and NBIC. The catastrophe reinsurance programs are allocated amongst traditional reinsurers, catastrophe bonds issued by Citrus Re and FHCF. The FHCF covers Florida risks only and we participate at 45%. Citrus Re, which provides fully collateralized multi-year coverage, covers catastrophe losses incurred by Heritage P&C only through the 2016 Class D and 2017-1 Notes, and covers catastrophe losses incurred by Heritage P&C, Zephyr and NBIC through the 2016 Class E Note. Our third-party reinsurers are either rated “A-” or higher by A.M. Best or S&P or are fully collateralized, to reduce credit risk.

The reinsurance program, which is segmented into layers of coverage, protects the Company for excess property catastrophe losses and loss adjustment expenses. The 2018-2019 reinsurance program provides first event coverage up to $1.6 billion for Heritage P&C, first event coverage up to $801.0 million for Zephyr, and first event coverage up to $1.0 billion for NBIC. Our first event retention for each insurance company subsidiary follows: Heritage P&C - $20.0 million; Zephyr - $20.0 million; NBIC – $12.8 million. Our second and third event retentions for each insurance company subsidiary follows: Heritage P&C - $16.0 million; Zephyr - $16.0 million; NBIC – $8.8 million.

Our program was placed on a cascading basis which provides greater horizontal protection in a multiple small events scenario and features additional coverage enhancements. This coverage exceeds the requirements established by the Companies’ rating agency, Demotech, Inc., the Florida Office of Insurance Regulation, the Hawaii Insurance Division, and the Rhode Island Department of Business Regulation. For the twelve months ending May 31, 2019, no single uncollateralized private reinsurer represented more than 10% of the overall limit purchased from our total reinsurance coverage.

We are responsible for all losses and loss adjustment expenses in excess of our reinsurance program. For second or subsequent catastrophic events, our total available coverage depends on the magnitude of the first event, as we may have coverage remaining from layers that were not previously fully exhausted. An aggregate of $3.4 billion of limit purchased in 2018 includes reinstatement through the purchase of reinstatement premium protection. In total, we have purchased $3.5 billion of potential reinsurance coverage, including our retention, for multiple catastrophic events. Our ability to access this coverage, however, will be subject to the severity and frequency of such events.

The Company's estimated net cost for the 2018-2019 catastrophe reinsurance programs is approximately $252.0 million.

Gross Quota Share Reinsurance

NBIC purchased an 8% gross quota share reinsurance treaty effective June 1, 2018 which provides ground up loss recoveries of up to $1.0 billion. Prior to this treaty, NBIC’s gross quota share treaty was 18.75%.

Net Quota Share Reinsurance

NBIC’s Net Quota Share coverage is proportional reinsurance for which certain of our other reinsurance inures to the quota share (property catastrophe excess of loss and reinstatement premium protection and the second layer of the general excess of loss). An occurrence limit of $20.0 million for catastrophe losses is in effect on the quota share, subject to certain aggregate loss limits that vary by reinsurer. The amount and rate of reinsurance commissions slide, within a prescribed minimum and maximum, depending on loss performance. NBIC ceded 49.5% of net premiums and losses during 2018 to the Net Quota Share and 8% of the 2017 Net Quota Share was in runoff. The Net Quota Share program was renewed on December 31, 2018 ceding 52% of the net premiums and losses and 10% of the prior year quota share will run off.

Aggregate Coverage

A $1.1 billion of limit is structured on an aggregate basis (Top and Aggregate, Layer 1, Layer 2, Layer 3, Layer 4, Stub layers, Multi-Zonal, 2017-1 Notes and 2016 Class E Notes). To the extent that this coverage is not fully exhausted in the first catastrophic event, it provides coverage commencing at its reduced retention for second and subsequent events where underlying coverage has been previously exhausted. The Company purchased reinstatement premium protection for $669.0 million of this coverage, which can be reinstated one time. Layers (with exception to FHCF and 2016 Class D Notes) are “net” of a $40.0 million attachment point. Layers inure to the subsequent layers if the aggregate limit of the preceding layer(s) is exhausted, and the subsequent layer cascades down in its place.

NBIC placed 42.5% of an aggregate contract, which covers all catastrophe losses excluding named storms, on May 31, 2018, expiring December 31, 2018. The limit on the contract is $20.0 million, with a retention of $3.0 million and franchise deductible of $1.5 million.

NBIC placed 92% of an occurrence contract, which covers all catastrophe losses excluding named storms, on May 31, 2018, expiring December 31, 2018. The limit on the contract is $20.0 million with a retention of $20.0 million.

Per Risk Coverage

For southeast losses and northeast commercial residential losses, excluding losses from named storms, the Company purchased property per risk coverage for losses and loss adjustment expenses in excess of $1.0 million per claim. The limit recovered for an individual loss is $9.0 million and total limit for all losses is $27.0 million. There are two reinstatements available with additional premium due based on the amount of the layer exhausted. In addition, the Company purchased facultative reinsurance in excess of $10.0 million for any properties it insured where the total insured value exceeded $10.0 million. This coverage applied to Southeast losses and Northeast commercial residential losses, excluding losses from name storms.

General Excess of Loss

NBIC’s general excess of loss reinsurance protects NBIC from single risk losses, both property and casualty. The casualty coverage provided by this contract also responds on a “Clash” basis, meaning that multiple policies involved in a single loss occurrence can be aggregated into one loss and applied to the reinsurance contract. The coverage is in two layers in excess of NBIC’s retention of the first $300,000 of loss. The first layer is $450,000 excess $300,000 and the second layer is $2.75 million excess $750,000 (Casualty second layer is $1.25 million excess $750,000). Both layers are 92% placed with the gross quota share providing the additional 8% coverage.

Semi-Automatic Facultative Excess of Loss

NBIC’s automatic property facultative reinsurance protects NBIC from single risk losses, for property risks with a total insured value excess of $3.5 million subject to a limit.

The Company’s reinsurance arrangements had the following effect on certain items in the condensed consolidated statement of income for the three and nine months ended September 30, 2019 and 2018:

As of September 30, 2019, the Company reported $208.7 million in unpaid losses and loss adjustment expenses, net of reinsurance which included $158.2 million attributable to IBNR net of reinsurance recoverable, or 75.8% of net reserves for unpaid losses and loss adjustment expenses.

The Company’s losses incurred for the third quarter ended September 30, 2019 and 2018 reflect favorable development of $0.4 million and $3.2 million, respectively, associated with management’s best estimate of the actuarial loss and LAE reserves with consideration given to Company specific historical loss experience. While a portion of the 2018 development includes additional retention for hurricane losses, the majority of the 2018 loss development related to personal lines litigated and assignment of benefit claims from 2016 and 2017 accident years.

NOTE 14. LONG-TERM DEBT

Convertible Senior Notes

In August 2017 and September 2017, the Company issued in aggregate $136.8 million of 5.875% Convertible Senior Notes (“Convertible Notes”) maturing on August 1, 2037, unless earlier repurchased, redeemed or converted. Interest is payable semi-annually in arrears, on February 1, and August 1 of each year, commencing in 2018.

As of September 30, 2019, the Company had $21.1 million of the Convertible Notes outstanding, net of issuance and debt discount costs in aggregate of approximately, $2.3 million. For nine months ended 2019 and 2018, the Company made interest payments of approximately $1.5 million and $7.7 million, respectively on the Convertible Notes.

Debt Extinguishment

On February 19, 2019, the Company reacquired $5.8 million of its outstanding Convertible Notes for approximately $2.9 million, which was paid in cash and the issuance of 285,201 shares of the Company’s common stock valued at $4.2 million. The repurchase resulted in a $48,000 non-operating loss.

Senior Secured Credit Facility

In December 2018, the Company entered into a five-year, $125.0 million credit agreement (the “Credit Agreement”) with a syndicate of lenders consisting of $75.0 million senior secured term loan facility (the “Term Loan Facility”) and a $50.0 million senior secured revolving credit facility (the “Revolving Credit Facility” and together with the Term Loan Facility, the “Credit Facilities”).

Term Loan Facility: The principal amount of the Term Loan Facility amortizes in quarterly installments, beginning with the close of the fiscal quarter ending March 31, 2019, in an amount equal to $1.9 million per quarter, with the remaining balance payable at maturity. As of December 31, 2018, there was $75.0 million in aggregate principal outstanding on the Term Loan Facility. As of September 30, 2019, the balance of the term loan was $71.3 million. For the nine months ended September 30, 2019, the Company made interest payments of approximately $2.3 million on the term loan.

Revolving Credit Facility: The Revolving Credit Facility allows for borrowings of up to $50.0 million inclusive of a $5.0 million sublimit for the issuance of letters of credit and a $10.0 million sublimit for swingline loans. As of December 31, 2018, there was $20.0 million in aggregate principal outstanding under the Revolving Credit Facility. As of September 30, 2019, the Company had $10.0 million of borrowings and no letters of credit outstanding under the Revolving Credit Facility. For the nine months ended September 30, 2019, the Company made interest payments of approximately $421,000 under the credit facility, respectively.

At September 30, 2019, the Company’s effective interest rate for the Term Loan Facility was 5.625% and 5.3125% for the Revolving Credit Facility. The Company monitors the rates prior to the reset date which allows it to establish if the payment is monthly or quarterly payment based on the most beneficial rate used to calculate the interest payment.

Mortgage Loan

In October 2017, the Company and its subsidiary, Skye Lane Properties LLC, jointly obtained a commercial real estate mortgage loan in the amount of $12.7 million, bearing interest of 4.95% per annum and maturing on October 30, 2027. On October 30, 2022, the interest rate shall adjust to an interest rate equal to the annualized interest rate of the United States 5-year Treasury Notes as reported by Federal Reserve on a weekly average basis plus 3.10%. The Company makes monthly principal and interest payments against the loan. For each of the respective nine-month periods ended September 30, 2019 and 2018, the Company made principal and interest payments of approximately $670,000 on the mortgage loan.

FHLB Loan Agreements

In December 2018, a subsidiary of the Company received a fixed interest rate 3.094% cash loan of $19.2 million from the Federal Home Loan Bank (“FHLB”) Atlanta. In connection with the agreement, the subsidiary became a member of FHLB. Membership in the FHLB required an investment in FHLB’s common stock which was purchased in December 2018 and valued at $1.4 million. Additionally, the transaction required securities be pledged as collateral. As of September 30, 2019, the fair value of the collateralized securities was $24.5 million and the equity investment in FHLB common stock was $1.4 million. As of September 30, 2019, the Company made quarterly interest payments of approximately $452,000 per the terms of the agreement. The Company has also purchased common stock from FHLB Des Moines, and FHLB Boston valued at $140,200 and $76,600, respectively.

NOTE 16. STATUTORY ACCOUNTING AND REGULATIONS

State laws and regulations, as well as national regulatory agency requirements, govern the operations of all insurers such as our insurance subsidiaries. The various laws and regulations require that insurers maintain minimum amounts of statutory surplus and risk-based capital, restrict insurers’ ability to pay dividends, restrict the allowable investment types and investment mixes, and subject the Company’s insurers to assessments.

The Company’s insurance subsidiaries must maintain capital and surplus ratios or balances as determined by the regulatory authority of the states in which they are domiciled. Heritage P&C is required to maintain capital and surplus equal to the greater of $15 million or 10% of their respective liabilities. Zephyr is required to maintain a deposit of $750,000 in a federally insured financial institution. NBIC is required to maintain capital and surplus of $3.0 million. The combined statutory surplus for Heritage P&C, Zephyr and NBIC was $337.3 million at September 30, 2019. The combined statutory surplus for Heritage P&C, Zephyr and NBIC was $376.3 million at December 31, 2018. State law also requires the Company’s insurance subsidiaries to adhere to prescribed

premium-to-capital surplus ratios, with which the Company is in compliance. At September 30, 2019, our insurance subsidiaries met the financial and regulatory requirements of the states in which they do business.

NOTE 17. COMMITMENTS AND CONTINGENCIES

The Company is involved in claims-related legal actions arising in the ordinary course of business. The Company accrues amounts resulting from claims-related legal actions in unpaid losses and loss adjustment expenses during the period that it determines an unfavorable outcome becomes probable and it can estimate the amounts. Management makes revisions to its estimates based on its analysis of subsequent information that the Company receives regarding various factors, including: (i) per claim information; (ii) company and industry historical loss experience; (iii) judicial decisions and legal developments in the awarding of damages; and (iv) trends in general economic conditions, including the effects of inflation. When determinable, the Company discloses the range of possible losses in excess of those accrued and for reasonably possible losses.

NOTE 18. RELATED PARTY TRANSACTIONS

The Company has been party to various related party transactions involving certain of its officers, directors and significant stockholders as set forth below. The Company has entered into each of these arrangements without obligation to continue its effect in the future and the associated expense was immaterial to its results of operations or financial position as of September 30, 2019 and 2018.

•

In January 2017, the Company entered into a consulting agreement with Mrs. Shannon Lucas, the wife of the Chairman and CEO, in which she agreed to provide consulting services related to the Company’s catastrophe reinsurance and risk management program at a rate of $400 per hour. The consulting agreement has no specific term and either party may terminate the agreement upon providing written notice. Additionally, she serves as a director of Heritage P&C with an annual compensation of $150,000. For the nine months ended September 30, 2019 and 2018, the Company paid consulting fees to Ms. Lucas of approximately $256,000 and $575,000, respectively.

•

In July 2019, the Board of Directors appointed Mark Berset to the Board of Directors of the Company. Mr. Berset will be entitled to an annual compensation of $150,000. Mr. Berset is also the Chief Executive Officer of Comegys Insurance Agency, Inc. (“Comegys”), an independent insurance agency that writes policies for Company. The Company pays commission to Comegys based upon standard industry rates consistent with those provided to the Company’s other insurance agencies. There are no arrangements or understandings between Mr. Berset and any other persons with respect to his appointment as a director. For the nine months ended September 30, 2019 and 2018, the Company paid agency commission to Comegy of approximately $557,700 and $375,550, respectively.

NOTE 19. EMPLOYEE BENEFIT PLANS

The Company provides a 401(k) plan for substantially all employees. The Company provides a matching contribution of 100% on the first 3% of employees’ contribution and 50% on the next 2% of the employees’ contribution to the plan. The maximum match is 4%. For the three and nine months ended September 30, 2019 and 2018, the contributions made to the plan on behalf of the participating employees were approximately $213,000 and $756,000, and $215,000 and $973,000, respectively.

The Company provides for its employees a partially self-insured healthcare plan and benefits. For the three and nine months ended September 30, 2019 and 2018, incurred medical premium costs amounted to an aggregate of $611,000 and $2.4 million and $1.0 million and $2.3 million, respectively. An additional liability of approximately $391,000 is recorded for unpaid claims as of September 30, 2019. A stop loss reinsurance policy caps the maximum loss that could be incurred by the Company under the self-insured plan. The Company’s stop loss coverage per employee is $150,000 for which any excess cost would be covered by the reinsurer subject to an aggregate limit for losses in excess of $1.5 million which would provide up to $1.0 million of coverage. Any excess of the $1.5 million retention and the $1 million of aggregate coverage would be borne by the Company. The aggregate stop loss commences once our expenses exceed 125% of the annual aggregate expected claims.

NOTE 20. EQUITY

The total amount of authorized capital stock consists of 50,000,000 shares of common stock and 5,000,000 shares of preferred stock.

Upon the Company’s liquidation, dissolution or winding up, the holders of common stock will be entitled to receive ratably its net assets available after the payment of all debts and other liabilities and subject to the prior rights of holders of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. There are no redemption or sinking fund provisions applicable to the common stock.

Stock Repurchase Program

On August 1, 2018, the Company announced that its Board of Directors authorized a stock repurchase program authorizing the Company to repurchase up to $50.0 million of its common stock through December 31, 2020 under our current Rule 10b5-1 trading plan, which allows the Company to purchase shares below a predetermined price per share. For the three months ended September 30, 2019, the Company purchased 316,383 shares of its common stock for $4.5 million. As of September 30, 2019, the Company repurchased in aggregate 821,763 shares of its common stock since authorizing the stock repurchase program for $11.9 million.

At September 30, 2019, the Company has the capacity to repurchase $38.1 million of its common shares until December 2020. In addition, the Company acquired 4,620 shares and 12,620 shares for approximately $68,000 and $118,000 during three and nine months ended September 30, 2019, respectively, that were not part of the publicly announced share repurchase authorization. These shares consisted of shares retained to cover payroll withholding taxes in connection with the vesting of restricted stock awards.

The declaration and payment of any future dividends will be subject to the discretion of the Board of Directors and will depend on a variety of factors including the Company’s financial condition and results of operations.

NOTE 21. STOCK-BASED COMPENSATION

Restricted Stock

The Company has adopted the Heritage Insurance Holdings, Inc., Omnibus Incentive Plan (the “Plan”) effective on May 22, 2014. The Plan authorized 2,981,737 shares of common stock for issuance under the Plan for future grants.

At September 30, 2019 there were 1,326,018 shares available for grant under the Plan. The Company recognizes compensation expense under ASC 718 for its stock-based payments based on the fair value of the awards.

In 2018, the Company granted 155,801 restricted shares vesting over three to five years, to the Company’s executives and other key employees. No restricted stock was granted during the nine months ended September 30, 2019.

The Plan authorizes the Company to grant stock options at exercise prices equal to the fair market value of the Company’s stock on the dates the options are granted. Any options granted would typically have a maximum term of ten years from the date of grant and vest primarily in equal annual installments over a range of one to five-year periods following the date of grant for employee options. If a participant’s employment relationship ends, the participant’s vested awards would remain exercisable for the shorter of a period of 30 days or the period ending on the latest date on which such award could have been exercisable. The fair value of each option grant is separately estimated for each grant date. The fair value of each option is amortized into compensation expense on a straight-line basis between the grant date for the award and each vesting date. The Company estimates the fair value of all stock option awards as of the date of the grant by applying the Black-Scholes-Merton multiple-option pricing valuation model. The application of this valuation model involves assumptions that are judgmental and highly sensitive in the determination of compensation expense. The Company has not granted any stock options since 2015 and all unexercised stock options have since been forfeited.

The Company has also granted shares of its common stock subject to certain restrictions under the Plan. Restricted stock awards granted to employees vest in equal installments generally over a five-year period from the grant date subject to the recipient’s continued employment. The fair value of restricted stock awards is estimated by the market price at the date of grant and amortized on a straight-line basis to expense over the period of vesting. Recipients of restricted stock awards have the right to receive dividends.

Restricted stock activity for the quarter ended September 30, 2019 is as follows:

				Weighted-Average
				Grant-Date Fair
	Number of shares			Value per Share
Non-vested, at December 31, 2018		605,801		$	19.30
Granted		—			—
Vested		(22,647	)		14.28
Canceled and surrendered		(12,620	)		14.24
Non-vested, at September 30, 2019		570,534		$	19.61

Awards are being amortized to expense over the three to five-year vesting period. The Company recognized $4.0 million and $3.9 million of compensation expense for the nine months ended September 30, 2019 and 2018, respectively. There was approximately $6.9 million of unrecognized compensation expense related to the un-vested restricted stock at September 30, 2019. The Company expects to recognize substantially all of remaining compensation expense over the next 1.3 years. For the nine months ended September 30, 2019, 35,267 shares of restricted stock were vested and released, all of which had been granted to employees. Of the shares released to employees, 12,620 shares were withheld by the Company to cover withholding taxes of $186,000. For the comparable period of 2018, no shares were vested and released.

NOTE 22. SUBSEQUENT EVENTS

The Company performed an evaluation of subsequent events through the date the condensed consolidated financial statements were issued and determined there were no recognized or unrecognized subsequent events that would require an adjustment or additional disclosure in the condensed consolidated financial statements as of September 30, 2019.

On October 31, 2019, the Company announced that its Board of Directors declared a $0.06 per share quarterly dividend payable on January 3, 2020 to stockholders of record as of December 16, 2019.

NM= Not Meaningful

Gross premiums written were $237.3 million in third quarter 2019, up 1.6% from $233.6 million in the prior year quarter. The increase reflects 7.9% growth outside Florida, partly offset by a 4.8% exposure management driven decline in Florida, particularly in the state’s Tri-County region. The Florida decline reflects a deceleration from second quarter 2019’s 11.9% decrease.

Premiums-in-force were $926.8 million, up 0.5% from the second quarter of 2019, with the increase stemming from 2.1% growth outside Florida, partly offset by a 1.0% decline in Florida. The Florida decline reflects a deceleration from 2Q19’s 3.4% decline from the first quarter of 2019.

Gross premiums earned

Gross premiums earned were $231.6 million in the third quarter of 2019, down 1.1% from $234.2 million in the prior year quarter. The decrease primarily reflects organic gross premiums written year-over-year declines in the second quarter of 2019 and the third and fourth quarters of 2018, partly offset by positive organic gross premiums written growth in the first and third quarters of 2019.

Ceded premiums earned

Ceded premiums earned were $107.8 million in the third quarter of 2019, down 7.0% from $115.9 million in the prior year quarter. The decrease is primarily attributable to continued NBIC-related reinsurance synergies from the run-off of multi-year contracts prior to acquisition by Heritage, and a reduction in NBIC’s gross quota share reinsurance program, which decreased from 18.75% to 8.0% as of June 1, 2018 and was eliminated as of June 1, 2019. NBIC’s gross quota share reduction was partly offset by additional catastrophe excess-of-loss reinsurance coverage and an increase in NBIC’s net quota share reinsurance program from 49.5% to 52.0% as of December 31, 2018.

Net premiums earned

Net premiums earned were $123.9 million in the third quarter of 2019, up 4.8% from $118.2 million in the prior year quarter. The increase reflects lower ceded premiums earned, partly offset by lower gross premiums earned, as described above.

Net investment income

Net investment income, inclusive of realized investment gains and unrealized gains on equity securities, was $4.5 million in the third quarter of 2019, up 15.4% from $3.9 million in the prior year quarter. The increase was primarily due to unrealized gains on equity securities. Investment income on the fixed income portfolio was relatively flat, as a lower interest rates were mostly offset by a larger invested asset base.

Other revenue

Other revenue was $3.4 million in the third quarter of 2019, up $0.2 million from $3.2 million in the prior year quarter.

Total revenue

Total revenue was $131.7 million in the third quarter of 2019, up 5.1% from $125.3 million in the prior year quarter. The increase primarily stems from higher net premiums earned, as described above.

	For the Three Months Ended September 30,

OPERATING EXPENSES:
Losses and loss adjustment expenses		70,052		58,695		11,357			19	%

Total operating expenses		118,215		111,079		7,136			6	%

Losses and loss adjustment expenses

Losses and loss adjustment expenses (“LAE”) were $70.1 million in the third quarter of 2019, up $11.4 million from $58.7 million in the prior year quarter. The increase primarily stems from lower cost savings from vertically integrated operations, higher current accident year non-hurricane weather losses and less favorable prior year reserve development, partly offset by lower current accident year catastrophe losses.

Policy acquisition costs

Policy acquisition costs were $26.7 million in the third quarter of 2019, in line with $26.6 million in the prior year quarter.

General and administrative expenses

General and administrative expenses were $21.5 million in the third quarter of 2019, down $4.3 million from $25.8 million in the prior year quarter. The decrease is primarily attributable to non-core business acquisition related expenses in the prior year quarter, partly offset by reduced ceding commission income in the current year quarter associated with changes to NBIC’s quota share reinsurance programs, as described above.

Interest and amortization of debt issuance costs

Interest expense and amortization of debt issuance costs was $2.4 million in the third quarter of 2019, down $2.8 million from $5.2 million in the prior year quarter. The decrease reflects a significant year-over-year reduction in long-term debt and a lower blended interest rate on outstanding debt associated with the 2018 debt refinancing transactions.

Provision for income taxes

Provision for income taxes was $3.0 million for both third quarter of 2019 and 2018. The effective tax rate for the current year quarter was 26.6%, 6.8 points below the prior year quarter’s 33.4% rate. Lower pre-tax income in the prior year quarter had an adverse impact on the effective tax rate for the period. Additionally, the third quarter 2018 effective tax rate was elevated due to a tax year 2017 true up of the income tax provision to the income tax return filed in 2018. The effective tax rate can fluctuate throughout the year as estimates used in the quarterly tax provision are updated with additional information throughout the year.

Net income

Net income was $8.1 million ($0.28 per diluted share) in the third quarter of 2019, compared to $6.0 million ($0.23 per diluted share) in the prior year quarter. The increase primarily reflects higher net premiums earned, a lower net expense ratio and lower interest expense, partly offset by a higher net loss ratio, as described above.

Ceded premium ratio

The ceded premium ratio was 46.5% in third quarter of 2019, down 3.0 points from 49.5% in the prior year quarter. The decrease is primarily attributable to reinsurance synergies associated with the renewal of remaining legacy NBIC reinsurance coverage on a consolidated basis and elimination of NBIC’s 8.0% gross quota share reinsurance program as of June 1, 2019, partly offset by additional catastrophe excess-of-loss reinsurance coverage and an increase in NBIC’s net quota share reinsurance program from 49.5% to 52.0% as of December 31, 2018.

Net loss and LAE ratio

The net loss ratio was 56.6% in third quarter of 2019, up 7.0 points from 49.6% in the prior year quarter. The increase primarily relates to lower cost savings from vertically integrated operations, higher current accident year non-catastrophe weather losses and less favorable prior year reserve development, partly offset by lower current accident year catastrophe losses and the beneficial ceded premium ratio impact of NBIC-related reinsurance synergies.

Net expense ratio

The net expense ratio was 38.9% in third quarter of 2019, down 5.4 points from 44.3% in the prior year quarter. The decrease primarily stems from non-core business acquisition related expenses in the prior year quarter and the beneficial ceded premium ratio impact of NBIC-related reinsurance synergies in the current year quarter.

Net combined ratio

The net combined ratio was 95.5% in third quarter of 2019, up 1.6 points from 93.9% in the prior year quarter. The increase stems from a higher net loss ratio, partly offset by a lower net expense ratio, as described above.

Gross premiums written

Gross premiums written were $702.5 million for the nine months ended September 30, 2019, in line with $701.6 million in the prior year period, as growth outside of Florida mostly offset exposure management within Tri-County, Florida.

Gross premiums earned

Gross premiums earned were $690.2 million for the nine months ended September 30, 2019, down 0.3% compared to $692.3 million in the prior year period.

Ceded premiums earned

Ceded premiums earned were $342.5 million for the nine months ended September 30, 2019, down 4.0% from $356.7 million in the prior year period. The decrease is primarily attributable to continued NBIC-related reinsurance synergies and an overall reduction to NBIC’s quota share reinsurance programs.

Net premiums earned

Net premiums earned were $347.6 million for the nine months ended September 30, 2019, up 3.6% from $335.6 million in the prior year period. The increase primarily stems from lower ceded premiums earned.

Net investment income

Net investment income, inclusive of realized investment gains and unrealized gains on equity securities for the nine months ended September 30, 2019, was $14.3 million, up 52.1% from $9.8 million in the prior year period. The increase relates primarily to improved market value on invested assets and a higher average invested asset balance, partly offset by a lower interest rate environment.

Other revenue

Other revenue was $10.9 million for the nine months ended September 30, 2019, relatively flat compared to $10.3 million in the prior year period.

Total revenue

Total revenue was $372.8 million for the nine months ended September 30, 2019, up 4.9% from $355.3 million in the prior year period. The increase primarily stems from higher net premiums earned and net investment income, as described above.

Losses and loss adjustment expenses

Losses and loss adjustment expenses (“LAE”) were $206.5 million for the nine months ended September 30, 2019, up $28.7 million from $177.8 million in the prior year period. The increase stems primarily from lower cost savings from vertically integrated operations and higher retained weather losses, partly offset by better prior year reserve development and lower attritional losses.

Policy acquisition costs

Policy acquisition costs were $79.8 million for the nine months ended September 30, 2019, up $21.6 million from $58.2 million in the prior year period. The increase primarily reflects the favorable impact of NBIC-related purchase accounting on the prior year period. The favorable purchase accounting impact occurred predominantly in the first two quarters of 2018 and was limited thereafter, as acquisition costs increased with new business. Policy acquisition costs also increased due to reduced ceding commission income in the current year period associated with a reduction to NBIC’s overall quota share reinsurance programs. NBIC’s gross quota share reinsurance program was reduced from 18.75% to 8.0% effective June 1, 2018 and was eliminated effective June 1, 2019, while NBIC’s net quota share reinsurance program increased from 49.5% to 52.0% effective December 31, 2018.

General and administrative expenses

General and administrative expenses were $58.5 million for the nine months ended September 30, 2019, down $13.7 million from $72.2 million in the prior year period. The decrease is primarily attributable to non-core business acquisition related expenses, costs associated with infrastructure growth and post-acquisition costs associated with NBIC-related systems implementation in the prior year period, partly offset by reduced ceding commission income in the current year period, as described above.

Interest and amortization of debt issuance costs

Interest expense and amortization of debt issuance costs were $6.5 million for the nine months ended September 30, 2019, down $8.9 million from $15.4 million in the prior year period. The decrease primarily reflects a significant year-over-year reduction in long-term debt and a lower blended interest rate on outstanding debt associated with the 2018 debt refinancing transactions.

Provision for income taxes

Provision for income taxes was $5.7 million and $9.1 million for the nine months ended September 30, 2019 and 2018, respectively. The effective tax rate for the current year is 26.4%, 1.7 points lower than the prior year’s 28.1%. The prior year period’s effective tax rate was elevated due to a tax year 2017 true up to the income tax return filed in 2018. The effective tax rate can fluctuate throughout the year as estimates used in the quarterly tax provision are updated with additional information throughout the year.

Net income

Net income for the nine months ended September 30, 2019 was $15.8 million ($0.54 per diluted share) compared to $23.2 million ($0.88 per diluted share) in the prior year period. The decrease primarily reflects a higher net loss ratio in the current year period and the favorable impact of NBIC-related purchase accounting on the prior year period’s net expense ratio, partly offset by an increase in net premiums earned and investment income and a decrease in interest expense.

Ceded premium ratio

The ceded premium ratio was 49.6% for the nine months ended September 30, 2019, down 1.9 points from 51.5% in the prior year period. The decrease is primarily attributable to continued NBIC-related reinsurance synergies and a reduction to NBIC’s overall quota share reinsurance programs, as described above.

Net loss and LAE ratio

The net loss and LAE ratio was 59.4% for the nine months ended September 30, 2019, up 6.4 points from 53.0% in the prior year period. The increase relates to lower income from vertically integrated operations and higher retained weather losses, partly offset by better prior year reserve development and the beneficial impact of NBIC-related reinsurance synergies.

Net expense ratio

The net expense ratio was 39.8% for the nine months ended September 30, 2019, up 1.0 points from 38.8% in the prior year period. The increase primarily stems from the favorable impact of NBIC-related purchase accounting on the prior year period, partly offset by non-core business acquisition related expenses in the prior year period and the beneficial ceded premium ratio impact of NBIC-related reinsurance synergies on the current year period.

Net combined ratio

The net combined ratio was 99.2% for the nine months ended September 30, 2019, up 7.4 points from 91.8 in the prior year period. The increase stems from higher net loss and expense ratios, as described above.

Liquidity and Capital Resources

As of September 30, 2019, we had $230.0 million of cash and cash equivalents, which primarily consisted of cash and money market accounts. We generally hold substantial cash balances to meet seasonal liquidity needs including amounts to pay quarterly reinsurance installments as well as meet the collateral requirements of Osprey Re Ltd. (“Osprey”), our captive reinsurance company. In addition, we have $13.8 million in restricted cash to meet our contractual obligations related to the catastrophe bonds issued by Citrus Re Ltd. as well as state insurance department depository requirements.

Osprey is required to maintain a collateral trust account equal to the risk that it assumes from our insurance company affiliates. At September 30, 2019, approximately $24 million was held in Osprey’s trust account.

Although we can provide no assurances, we believe that we maintain sufficient liquidity to pay our insurance company affiliates’ claims and expenses, as well as to satisfy commitments in the event of unforeseen events such as inadequate premium rates or reserve deficiencies. We believe our current capital resources, including funds available under our revolving credit facility (as described below), together with cash provided from our operations, will be sufficient to meet currently anticipated working capital requirements for at least the next twelve months. We maintain a comprehensive reinsurance program at levels management considers adequate to diversify risk and safeguard our financial position.

Operating Activities

Net cash provided by operating activities was $116.2 million for the nine months ended September 30, 2019 compared to cash provided of $60.3 million for the comparable period in 2018. The increase in cash from operating activities relates primarily to timing of cash flows associated with claim payment and reinsurance. during the first nine months of 2019 compared to the first nine months of 2018.

Investing Activities

Net cash used in investing activities for the nine months ended September 30, 2019 was $100.6 million as compared to cash provided of $19.1 million for the comparable period in 2018. The cash provided by investing activities in the first nine months of 2018 relates to investments sold during the quarter, primarily to fund payments of hurricane Irma claims pending reinsurance recoveries whereas we increased invested assets during the first nine months of 2019.

Financing Activities

Net cash used in financing activities for the nine months ended September 30, 2019 was $34.1 million, as compared to cash used in financing activities of $20.2 million for the comparable period in 2018. The increase in cash used in financing activities is due primarily to stock repurchased under the stock repurchase program in the current year and principal payments on the revolving credit line during 2019.

Credit Facilities

On December 14, 2018, Heritage Insurance Holdings, Inc. (the “Company”), as borrower, entered into a credit agreement (the “Credit Agreement”) by and among the Company, certain subsidiaries of the Company from time to time party thereto as guarantors, the lenders from time to time party thereto (the “Lenders”), Regions Bank, as Administrative Agent and Collateral Agent, BMO Harris Bank N.A., as Syndication Agent, Hancock Whitney Bank and Canadian Imperial Bank of Commerce, as Co-Documentation Agents, and Regions Capital Markets and BMO Capital Markets Corp., as Joint Lead Arrangers and Joint Bookrunners.

Pursuant to the Credit Agreement, the participating Lenders agreed to provide (1) a five-year senior secured term loan facility in an aggregate principal amount of $75 million (the “Term Loan Facility”) and (2) a five-year senior secured revolving credit facility in an aggregate principal amount of $50 million (inclusive of a $5 million sublimit for the issuance of letters of credit and a $10 million sublimit for swingline loans) (the “Revolving Credit Facility” and together with the Term Loan Facility, the “Credit Facilities”). As of September 30, 2019, the Company had in aggregate $71.3 million principal outstanding under the Term Loan Facility and $10.0 million of borrowings outstanding under the Revolving Credit Facility.

At our option, borrowings under the Credit Facilities bear interest at rates equal to either (1) a rate determined by reference to LIBOR (based on one, two, three or six-month interest periods), adjusted for statutory reserve requirements, plus an applicable margin (equal to 3.25% as of the Closing Date) or (2) a base rate determined by reference to the greatest of (a) the “prime rate” of Regions Bank, (b) the federal funds rate plus 0.50%, and (c) the LIBOR index rate applicable for an interest period of one month plus 1.00%, plus an applicable margin (equal to 2.25%).

The applicable margin for loans under the Credit Facilities varies from 3.25% per annum to 3.75% per annum (for LIBOR loans) and 2.25% to 2.75% per annum (for base rate loans) based on our consolidated leverage ratio. Interest payments with respect to the Credit Facilities are required either on a quarterly basis (for base rate loans) or at the end of each interest period (for LIBOR loans) or, if the duration of the applicable interest period exceeds three months, then every three months. As of September 30, 2019, the borrowing under our Credit Facilities were accruing interest at a rate of 5.625% per annum.

In addition to paying interest on outstanding borrowings under the Revolving Credit Facility, we are required to pay a quarterly commitment fee based on the unused portion of the Revolving Credit Facility, which is determined by our consolidated leverage ratio.

Each of the Revolving Credit Facility and the Term Loan Facility mature on December 14, 2023. The principal amount of the Term Loan Facility amortizes in quarterly installments, which began with the close of the fiscal quarter ended March 31, 2019, in an amount equal to $1,875,000 per quarter, payable monthly or quarterly, with the balance payable at maturity.

The Company may prepay the loans under the Credit Facilities, in whole or in part, at any time without premium or penalty, subject to certain conditions including minimum amounts and reimbursement of certain costs in the case of prepayments of LIBOR loans. In addition, the Company is required to prepay the loan under the Term Loan Facility with the proceeds from certain financing transactions, involuntary dispositions or asset sales (subject, in the case of asset sales, to reinvestment rights).

All obligations under the Credit Facilities are or will be guaranteed by each existing and future direct and indirect wholly owned domestic subsidiary of the Company, other than all of the Company’s current and future regulated insurance subsidiaries (collectively, the “Guarantors”).

The Company and the Guarantors entered into a Pledge and Security Agreement, on December 14, 2018 (the “Security Agreement”), in favor of Regions Bank, as collateral agent. Pursuant to the Security Agreement, amounts borrowed under the Credit Facilities are secured on a first priority basis by a perfected security interest in substantially all of the present and future assets of the Company and each Guarantor (subject to certain exceptions), including all of the capital stock of the Company’s domestic subsidiaries, other than its regulated insurance subsidiaries.

The Credit Agreement contains, among other things, covenants, representations and warranties and events of default customary for facilities of this type. The Company is required to maintain, as of each fiscal quarter (1) a maximum consolidated leverage ratio of 3.25 to 1.00 for each fiscal quarter ending on or before December 31, 2019, stepping down on each of the three anniversaries thereafter; (2) a minimum consolidated fixed charge coverage ratio of 1.20 to 1.00 and (3) a minimum consolidated net worth for the Company and its subsidiaries. Events of default include, among other events, (i) nonpayment of principal, interest, fees or other amounts; (ii) failure to perform or observe certain covenants set forth in the Credit Agreement; (iii) breach of any representation or warranty; (iv) cross-default to other indebtedness; (v) bankruptcy and insolvency defaults; (vi) monetary judgment defaults and material nonmonetary judgment defaults; (vii) customary ERISA defaults; (viii) a change of control of the Company; and (ix) failure to maintain specified catastrophe retentions in each of the Company’s regulated insurance subsidiaries.

Convertible Notes

On August 10, 2017, the Company and Heritage MGA, LLC (the “Guarantor”) entered into a purchase agreement (the “Purchase Agreement”) with Citigroup Global Markets Inc., as the initial purchaser (the “Initial Purchaser”), pursuant to which the Company agreed to issue and sell, and the Initial Purchaser agreed to purchase, $125.0 million aggregate principal amount of the Company’s 5.875% Convertible Senior Notes due 2037 (the “Convertible Notes”) in a private placement transaction pursuant to Rule 144A under the Securities Act, as amended (the “Securities Act”) (the “Offering”). The Purchase Agreement contained customary representations, warranties and agreements of the Company and the Guarantor and customary conditions to closing, indemnification rights and obligations of the parties and termination provisions. The net proceeds from the Offering, after deducting discounts and commissions and estimated offering expenses payable by the Company, were approximately $120.5 million. The Offering was completed on August 16, 2017.

The Company issued the Convertible Notes under an Indenture (the “Convertible Note Indenture”), dated August 16, 2017, by and among the Company, as issuer, the Guarantor, as guarantor, and Wilmington Trust, National Association, as trustee (the “Trustee”).

The Convertible Notes bear interest at a rate of 5.875% per year. Interest began accruing on August 16, 2017 and is payable semi-annually in arrears, on February 1 and August 1 of each year, starting on February 1, 2018. The Convertible Notes are senior unsecured obligations of the Company that rank senior in right of payment to the Company’s future indebtedness that is expressly subordinated in right of payment to the Convertible Notes; equal in right of payment to the Company’s unsecured indebtedness that is not so subordinated; effectively junior to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness or other liabilities incurred by the Company’s subsidiaries other than the Guarantor, which fully and unconditionally guarantee the Convertible Notes on a senior unsecured basis.

The Convertible Notes mature on August 1, 2037, unless earlier repurchased, redeemed or converted.

Holders may convert their Convertible Notes at any time prior to the close of business on the business day immediately preceding February 1, 2037, other than during the period from, and including, February 1, 2022 to the close of business on the second business day immediately preceding August 5, 2022, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2017, if the closing sale price of the Company’s common stock, for at least 20 trading days (whether or not consecutive) in the period of 30 consecutive trading days ending on the last trading day of the calendar quarter immediately preceding the calendar quarter in which the conversion occurs, is more than 130% of the conversion price of the Convertible Notes in effect on each applicable trading day; (2) during the ten consecutive business-day period following any five consecutive trading-day period in which the trading price for the Convertible Notes for each such trading day was less than 98% of the closing sale price of the Company’s common stock on such date multiplied by the then-current conversion rate; (3) if the Company calls any or all of the Convertible Notes for redemption, at any time prior to the close of business on the second business day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events.

During the period from and including February 1, 2022 to the close of business on the second business day immediately preceding August 5, 2022, and on or after February 1, 2037 until the close of business on the second business day immediately preceding August 1, 2037, holders may surrender their Convertible Notes for conversion at any time, regardless of the foregoing circumstances.

The conversion rate for the Convertible Notes was initially 67.0264 shares of common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $14.92 per share of common stock). The conversion rate is subject to adjustment in certain circumstances and is subject to increase for holders that elect to convert their Convertible Notes in connection with certain corporate transactions (but not, at the Company’s election, a public acquirer change of control (as defined in the Convertible Note Indenture)) that occur prior to August 5, 2022.

Upon the occurrence of a fundamental change (as defined in the Convertible Note Indenture) (but not, at the Company’s election, a public acquirer change of control (as defined in the Convertible Note Indenture)), holders of the Convertible Notes may require the Company to repurchase for cash all or a portion of their Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

Except as described below, the Company may not redeem the Convertible Notes prior to August 5, 2022. On or after August 5, 2022 but prior to February 1, 2037, the Company may redeem for cash all or any portion of the Convertible Notes, at the Company’s option, at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Convertible Notes, which means that the Company is not required to redeem or retire the Convertible Notes periodically. Holders of the Convertible Notes are able to cause the Company to repurchase their Convertible Notes for cash on any of August 1, 2022, August 1, 2027 and August 1, 2032, in each case at 100% of their principal amount, plus accrued and unpaid interest to, but excluding, the relevant repurchase date.

The Convertible Note Indenture contains customary terms and covenants and events of default. If an Event of Default (as defined in the Indenture) occurs and is continuing, the Trustee by notice to the Company, or the holders of at least 25% in aggregate principal amount of the Convertible Notes then outstanding by notice to the Company and the Trustee, may declare 100% of the principal of, and accrued and unpaid interest, if any, on, all the Convertible Notes to be immediately due and payable. In the case of certain events of bankruptcy, insolvency or reorganization (as set forth in the Convertible Note Indenture) with respect to the Company, 100% of the principal of, and accrued and unpaid interest, if any, on, the Notes automatically become immediately due and payable.

In the second quarter of 2018, the Company repurchased $10.6 million principal amount of Convertible Notes for cash. In the fourth quarter of 2018 and first quarter of 2019, the Company repurchased Convertible Notes in the aggregate principal amount of $81.6 million for a combination of cash and the issuance of an aggregate of 3,880,653 shares of the Company’s common stock, leaving $23.4 million in aggregate principal amount outstanding. There were no repurchases of Convertible Notes in the third quarter of 2019.

FHLB Loan Agreements

In December 2018, a subsidiary of the Company pledged U.S. government and agency fixed maturity securities with an estimated fair value of $31.0 million as collateral and received $19.2 million in a cash loan under an advance agreement with the Federal Home Loan Bank (“FHLB”) Atlanta. The loan originated on December 12, 2018 and bears a fixed interest rate of 3.094% with interest payments due quarterly commencing in March 2019. The principal balance on the loan has a maturity date of December 13, 2023. In connection with the agreement, the subsidiary became a member of FHLB. Membership in the FHLB required an investment in FHLB’s common stock which was purchased on December 31, 2018 and valued at $1.4 million. The subsidiary is permitted to withdraw any portion of the pledged collateral over the minimum collateral requirement at any time, other than in the event of a default by the subsidiary. The proceeds from the loan was used to prepay the Company’s Senior Secured Notes due 2023 (“Senior Notes”) in 2018. The Company does not have any Senior Notes outstanding as of September 30, 2019.

When we prepare our condensed consolidated financial statements and accompanying notes in conformity with U.S. generally accepted accounting principles (GAAP), we must make estimates and assumptions about future events that affect the amounts we report. Certain of these estimates result from judgments that can be subjective and complex. As a result of that subjectivity and complexity, and because we continuously evaluate these estimates and assumptions based on a variety of factors, actual results could materially differ from our estimates and assumptions if changes in one or more factors require us to make accounting adjustments. During the three and nine months ended September 30, 2019, we reassessed our critical accounting policies and estimates as disclosed within our 2018 Form 10-K. As disclosed in Note 1. Basis of Presentation and Significant Accounting Policies we adopted on January 1, 2019, ASU 2016-02, Leases, and we have made no further material changes or additions with regard to such policies and estimates.

Represents the principal and interest payments per the terms of the Credit Facility debt.

Seasonality of our Business

Our insurance business is seasonal as hurricanes typically occur during the period from June 1 through November 30 each year and winter storms generally impact the first and fourth quarters of each year. With our catastrophe reinsurance program effective on June 1 each year, any variation in the cost of our reinsurance, whether due to changes to reinsurance rates or changes in the total insured value of our policy base, will occur and be reflected in our financial results beginning June 1 of each year, subject to certain adjustments.

Off-Balance Sheet Arrangements

We do not have transactions with unconsolidated entities, such as entities often referred to as structured financial or special purpose entities, whereby we have financial guarantees, subordinated retained interest, derivative instruments, or other contingent arrangements that expose us to material continuing risks, contingent liabilities or any other obligation under a variable interest in an unconsolidated entity that provides financial, liquidity, market risk, or credit risk support to us.

Recent Accounting Pronouncements

The information set forth under Note 1 to the condensed consolidated financial statements under the caption “Basis of Presentation and Significant Accounting Policies” is incorporated herein by reference. We do not expect any recently issued accounting pronouncements to have a material effect on our condensed consolidated financial statements.

JOBS Act

We qualify as an “emerging growth company” under the JOBS Act. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies. We are in the process of evaluating the benefits of relying on other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if as an emerging growth company we choose to rely on such exemptions, we may not be required to, among other things, (i) provide an auditor’s attestation report on our systems of internal controls over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be

adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the condensed consolidated financial statements (auditor discussion and analysis), and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer’s compensation to median employee compensation. These exemptions will apply until we no longer meet the requirements of being an emerging growth company. We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of our initial public offering, (b) in which we have total annual gross revenue of at least $1.07 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (2) the date on which we have issued more than $1 billion in non-convertible debt during the prior three-year period. We expect that we will no longer qualify as an emerging growth company on December 31, 2019, as it will be the last day of the fiscal year following the fifth anniversary of the completion of our initial public offering.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Our investment portfolios at September 30, 2019 included fixed maturity and equity securities, the purposes of which are not for trading or speculation. Our main objective is to maximize after-tax investment income and maintain sufficient liquidity to meet policyholder obligations while minimizing market risk, which is the potential economic loss from adverse fluctuations in securities’ prices. We consider many factors including credit ratings, investment concentrations, regulatory requirements, anticipated fluctuation of interest rates, durations and market conditions in developing investment strategies. Investment securities are managed by a group of nationally recognized asset managers and are overseen by the investment committee appointed by our board of directors. Our investment portfolios are primarily exposed to interest rate risk, credit risk and equity price risk. We classify our fixed maturity securities as available-for-sale and report any unrealized gains or losses, net of deferred income taxes, as a component of other comprehensive income within our stockholders’ equity. We classify our equity securities as available-for-sale and report any unrealized gains or losses in the income statement. As such, any material temporary changes in the fair value of such securities can adversely impact the carrying value of our stockholders’ equity.

Interest Rate Risk

Our fixed maturity securities are sensitive to potential losses resulting from unfavorable changes in interest rates. We manage the risk by analyzing anticipated movement in interest rates and considering our future capital needs.

As of August 31, 2019, the federal funds rate was in the range of 2.00% to 2.25%. On September 18, 2019, the Federal Reserve reduced the federal funds rate 25 basis points to a range of in the range of 1.75% to 2.00%. This is the second time the Federal Reserve has reduced the federal funds rate by 25 basis points in fiscal 2020 after periodically raising the rate from December 2015 through May 2019.

The following table illustrates the impact of hypothetical changes in interest rates to the fair value of our fixed maturity securities at September 30, 2019 (in thousands):

Hypothetical Change in Interest rates	Estimated Fair Value After Change		Change In Estimated Fair Value			Percentage Increase (Decrease) in Estimated Fair Value
300 basis point increase	$	551,298	$	(64,786	)		(10.5	)%
200 basis point increase	$	572,909	$	(43,175	)		(7.0	)%
100 basis point increase	$	594,504	$	(21,580	)		(3.5	)%
100 basis point decrease	$	637,645	$	21,561			3.5	%
200 basis point decrease	$	655,170	$	39,086			6.3	%
300 basis point decrease	$	661,200	$	45,116			7.3	%

Credit Risk

Credit risk can expose us to potential losses arising principally from adverse changes in the financial condition of the issuer of our fixed maturities. We mitigate this risk by investing in fixed maturities that are generally investment grade and by diversifying our investment portfolio to avoid concentrations in any single issuer or market sector. A majority of the securities in an unrealized loss position as of September 30, 2019 held an A+ rating or better. We do not intend to sell these investments until recovery of their amortized cost basis or maturity, and further believe that it is not more-likely-than-not that we will be required to sell these investments prior to that time. Our assessment that an investment is not other-than-temporary impaired could change in the future due to new developments or changes in our strategies or assumptions related to any particular investment.

The following table presents the composition of our fixed maturity portfolio by rating at September 30, 2019 (in thousands):

Comparable Rating	Amortized Cost		% of Total Amortized Cost			Estimated Fair Value		% of total Estimated Fair Value
AAA	$	56,606		9.4	%	$	57,634		9.4	%
AA+	$	212,221		35.1	%	$	214,665		34.9	%

Total	$	604,821		100	%	$	616,084		100	%

Equity Price Risk

Our equity investment portfolio at September 30, 2019 consists of $1.6 million of Federal Home Loan Bank common stock, the investment is recorded at cost and adjusted, if and when subsequent price changes are provided by the institution. Such changes in the basis of the equity investment are recognized in net holding gains and losses on the Company’s consolidated statements of operations. As of September 30, 2019, the Company has not recognized any price changes on the investment.

Foreign Currency Exchange Risk

At September 30, 2019, we did not have any material exposure to foreign currency related risk.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) that are designed to assure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

As required by Exchange Act Rule 13a-15(b), as of the end of the period covered by this Quarterly Report, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2019.

Changes in Internal Control over Financial Reporting

There has been no change in our internal controls over financial reporting during our most recent quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We implemented internal controls to ensure we adequately assessed the impact of the new accounting standards related to leases on our condensed consolidated financial statements to facilitate their adoption on January 1, 2019. There were no significant changes to our internal control over financial reporting due to the adoption of the new standard.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The Company is a party to claims and legal actions arising routinely in the ordinary course of our business. Although we cannot predict with certainty the ultimate resolution of the claims and lawsuits asserted against us, we do not believe that any currently pending legal proceedings to which we are a party will have a material adverse effect on our consolidated financial position results of operations or cash flow.

Item 1A. Risk Factors

The risk factors disclosed in the section entitled “Risk Factors” in our 2018 Form 10-K set forth information relating to various risks and uncertainties that could materially adversely affect our business, financial condition and operating results. Those risk factors continue to be relevant to an understanding of our business, financial condition and operating results. No material changes have occurred with respect to those risk factors.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Issuer purchases of equity securities

During the three months ended September 30, 2019, we purchased 316,383 shares of common stock for an aggregate purchase of $4.5 million under our share repurchase program. In addition, the Company acquired 4,620 shares for a total cost of $68,000 during the three months ended September 30, 2019 that were not part of the publicly announced share repurchase program authorization. These shares were delivered to the Company by employees to satisfy tax withholding obligations in connection with the vesting of restricted stock awards.

A summary of our common stock repurchases during the three months ended September 30, 2019 is set forth in the table below (in thousands, except shares):

	Total Number of Shares Purchased	Average Price Paid Per Share ⁽¹⁾	Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs⁽²⁾	Dollar Value of Shares that May Yet be Purchased Under the Plans or Programs
July 1, 2019 through July 31, 2019	—	$ —	—	$42,655
August 1, 2019 through August 31, 2019	316,383	$14.35	316,383	$38,106
September 1, 2019 September 30, 2019	4,620	$14.01	—	$38,106
Total	321,003		316,383

(1)

Average price paid per share excludes cash paid for commissions.

(2)

On August 1, 2018, the Company announced that its Board of Directors authorized a stock repurchase program authorizing the Company to repurchase up to $50 million of its common stock through December 31, 2020 under our current Rule 10b5-1 trading plan, which allows the Company to purchase shares below a predetermined price per share.

Overview

Significant Reinsurance Contracts

2019-2020 Excess of Loss Reinsurance Programs

Catastrophe Excess of Loss Reinsurance

The Company's estimated net cost for the 2019-2020 catastrophe reinsurance programs is approximately $249.2 million.

Gross Quota Share Reinsurance

Net Quota Share Reinsurance

Aggregate Coverage

Per Risk Coverage

General Excess of Loss

Semi-Automatic Facultative Excess of Loss

NBIC’s automatic property facultative reinsurance protects NBIC from single risk losses, for property risks with a total insured value excess of $3.5 million subject to a limit.

2018 – 2019 Reinsurance Program

Catastrophe Excess of Loss Reinsurance

Our program was placed on a cascading basis which provides greater horizontal protection in a multiple small events scenario and features additional coverage enhancements. This coverage exceeds the requirements established by the Companies’ rating agency, Demotech, Inc., the Florida Office of Insurance Regulation, the Hawaii Insurance Division, and the Rhode Island Department of Business Regulation. For the twelve months ending May 31, 2019, no single uncollateralized private reinsurer represented more than 10% of the overall limit purchased from our total reinsurance coverage.

We are responsible for all losses and loss adjustment expenses in excess of our reinsurance program. For second or subsequent catastrophic events, our total available coverage depends on the magnitude of the first event, as we may have coverage remaining from layers that were not previously fully exhausted. An aggregate of $3.4 billion of limit purchased in 2018 includes reinstatement through the purchase of reinstatement premium protection. In total, we have purchased $3.5 billion of potential reinsurance coverage, including our retention, for multiple catastrophic events. Our ability to access this coverage, however, will be subject to the severity and frequency of such events.

The Company's estimated net cost for the 2018-2019 catastrophe reinsurance programs is approximately $252.0 million.

Gross Quota Share Reinsurance

Net Quota Share Reinsurance

NBIC’s Net Quota Share coverage is proportional reinsurance for which certain of our other reinsurance inures to the quota share (property catastrophe excess of loss and reinstatement premium protection and the second layer of the general excess of loss). An occurrence limit of $20.0 million for catastrophe losses is in effect on the quota share, subject to certain aggregate loss limits that vary by reinsurer. The amount and rate of reinsurance commissions slide, within a prescribed minimum and maximum, depending on loss performance. NBIC ceded 49.5% of net premiums and losses during 2018 to the Net Quota Share and 8% of the 2017 Net Quota Share was in runoff. The Net Quota Share program was renewed on December 31, 2018 ceding 52% of the net premiums and losses and 10% of the prior year quota share will run off.

Aggregate Coverage

Per Risk Coverage

For southeast losses and northeast commercial residential losses, excluding losses from named storms, the Company purchased property per risk coverage for losses and loss adjustment expenses in excess of $1.0 million per claim. The limit recovered for an individual loss is $9.0 million and total limit for all losses is $27.0 million. There are two reinstatements available with additional premium due based on the amount of the layer exhausted. In addition, the Company purchased facultative reinsurance in excess of $10.0 million for any properties it insured where the total insured value exceeded $10.0 million. This coverage applied to Southeast losses and Northeast commercial residential losses, excluding losses from name storms.

General Excess of Loss

Semi-Automatic Facultative Excess of Loss

NBIC’s automatic property facultative reinsurance protects NBIC from single risk losses, for property risks with a total insured value excess of $3.5 million subject to a limit.

The Company’s reinsurance arrangements had the following effect on certain items in the condensed consolidated statement of income for the three and nine months ended September 30, 2019 and 2018:

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements include the accounts of Heritage Insurance Holdings, Inc. (together with its subsidiaries, the “Company”). These statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Certain financial information that is normally included in annual consolidated financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted. In the opinion of the Company’s management, all material intercompany transactions and balances have been eliminated and all adjustments consisting of normal recurring accruals which are necessary for a fair statement of the financial condition and results of operations for the interim periods have been reflected. The accompanying interim condensed consolidated financial statements and related footnotes should be read in conjunction with the Company’s audited consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 Form 10-K”).
Leases	Leases At the inception of a contract, we assess whether the contract is, or contains, a lease. The assessment is based on (1) whether the contract involves the use of distinct identified assets, (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether the Company has the right to direct the use of the asset. All significant lease arrangements are generally recognized at lease commencement. A right of use (“ROU”) asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (short term leases) and we recognize lease expense for these leases as incurred over the lease term. ROU assets represent our right to use an underlying asset during the reasonably certain lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise the option. Operating lease ROU assets and liabilities are recognized based on the present value of lease payments not yet paid. Lease payments may be fixed or variable, however, only fixed payments or in-substance fixed payments are included in determining the lease liability. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the term of the lease. We have lease agreements with lease and non-lease components, which are generally accounted for separately. We primarily use our incremental borrowing rates for our operating leases (rates are not readily determinable) and implicit rates for our financing leases in determining the present value of lease payments. In the first quarter of 2019, the Company adopted ASU 2016 -02 and did not recognize an opening adjustment to retained earnings as a result of the adoption of FASB 842. Refer to Note 5-Leases herein for further information.
Reclassification	Reclassification Certain prior year amounts have been reclassified to conform to the current year presentation.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) Lease Accounting, which requires that a lessee recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. As with previous guidance, there continues to be a differentiation between finance leases and operating leases, however this distinction now primarily relates to differences in the manner of expense recognition over time and in the classification of lease payments in the statement of cash flows. Lease assets and liabilities arising from both finance and operating leases will be recognized in the statement of financial position. ASU 2016-02 leaves the accounting for leases by lessors largely unchanged from previous GAAP. We adopted the guidance prospectively during the first quarter of 2019. As part of our adoption, we elected not to reassess historical lease classification or recognize short-term leases on our balance sheet. At implementation, we recorded approximately $2.8 million as right-of-use operating and financing leased assets in other assets and approximately $2.8 million of lease liabilities in accounts payable and other liabilities. We did not recognize an opening adjustment to retained earnings. Adoption of this standard did not materially impact the Company’s Condensed Consolidated Statements of Operations and Other Comprehensive Income and Statements of Cash Flows. See Note 5 to the condensed consolidated financial statements. Accounting Pronouncements Not Yet Adopted In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which provided certain improvements to ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01) and ASU 2016-13. FASB ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, introduces new guidance for the accounting for credit losses on financial instruments in with its scope. The new guidance provides for recognition of expected credit losses on certain types of financial instruments. This ASU requires immediate recognition of management estimates of current expected credit losses (“CECL”) and will apply to: (1) financial assets subject to credit losses which are currently measured at amortized costs; and (2) certain off-balance sheet credit exposures. This includes loans, held-to-maturity and/or available for sale debt securities, loan commitments, financial guarantees, and net investments in leases, as well as reinsurance and trade receivables. The measurement of credit losses for available-for-sale debt securities measured at fair value is not affected except that credit losses recognized are limited to the amount by which fair value is below amortized cost and carrying value adjustment is recognized through a valuation allowance which may change over time but once recorded cannot subsequently be reduced to an amount below zero. The ASU 2016-13 is effective for public entities for interim and annual periods beginning after December 15, 2019, and for most affected instruments must be adopted using a modified retrospective approach, with a cumulative effect adjustment recorded to the beginning retained earnings balance. The Company’s implementation activities, which remain in process, include the development of models, methodologies, data input and assumptions to be used in estimating expected credit losses. The implementation primarily impacts the Company’s debt securities and reinsurance recoverable balances. The adoption of this standard is not expected to be material to our financial position, results of operations or cash flows. For information regarding other accounting standards that the Company has not yet adopted, refer to our Annual Report on Form 10-K, filed on March 12, 2019, the section of Note 1 of the notes to the consolidated financial statements entitled the “Accounting Pronouncement Not Yet Adopted”.
