Special Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q, or the Quarterly Report, and the exhibits hereto, contains or incorporates by reference estimates, predictions, opinions, projections and other statements that may be interpreted as “forward-looking statements” within the meaning of, and are made pursuant to the safe harbor provisions of, Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act and other applicable federal U.S. and U.K. laws, regulations and other legal principles. All statements other than statements of historical fact in this Quarterly Report are forward-looking statements. The forward-looking statements are contained principally in Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and Part II, Item 1A, “Risk Factors,” but are also contained elsewhere in this Quarterly Report. In some cases, you can identify forward-looking statements by the words “may,” “might,” “will,” “would,” “could,” “should,” “intend,” “plan,” “contemplate,” “expect,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “target,” “potential,” “continue,” and “ongoing” and other comparable expressions intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements involve substantial known and unknown risks, uncertainties and other factors that may cause our actual results, level of activity, operations, condition, liquidity, prospects, opportunities, performance, achievements and industry results, as well as those of the markets we serve or intend to serve, to differ materially from those currently anticipated. Forward-looking statements are not assurances of future performance. Although we believe that we have a reasonable basis for each forward-looking statement contained in this Quarterly Report, we caution you that these statements are based on a combination of facts and factors currently known by us, and our expectations of the future, about which we cannot be certain and that involve substantial risks and uncertainties. Such risks and uncertainties include, but are not limited to:

●

given our prior history of losses, our ability to achieve and sustain profitability and our ability to manage our growth;

●

our ability to continue to sell our T-SPOT.TB at current prices if, for example, our customers or prospective customers are unwilling to pay for our tests at current pricing levels or as a result of increased competition generally;

●

our ability to further develop, commercialize and achieve market acceptance of our current and future products;

●

our dependence on certain of our customers, suppliers and service providers;

●

potential changes in social, political, regulatory and economic conditions or laws and policies governing the health care system, tax laws of the United States, or the U.S., and laws and regulations impacting foreign trade in the U.S. and abroad, including the ongoing trade dispute between the U.S. and China, immigration, manufacturing, development and investment in the U.S. and in other territories and countries where we or our customers and suppliers operate;

Notes to Unaudited Condensed Consolidated Financial Statements

June 30, 2020

1. Business and basis of presentation

Description of business

Oxford Immunotec Global PLC, or the Company, is a global, high-growth diagnostics company focused on developing and commercializing proprietary tests for immunology and infectious disease by leveraging the technological, product development, manufacturing, quality, regulatory, and sales and marketing capabilities it has developed over its seventeen year history. The Company’s proprietary T-SPOT.TB test utilizes its T-SPOT technology platform to test for tuberculosis, which is the leading cause of infectious disease death worldwide.

Unaudited interim financial statements

The consolidated balance sheet presented as of December 31, 2019, has been derived from the Company’s audited consolidated financial statements as of that date. The consolidated financial statements and notes included in this Quarterly Report should be read in conjunction with the 2019 consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the Securities and Exchange Commission on March 6, 2020, or the 2019 Form 10-K.

Cash, cash equivalents, and restricted cash

The Company considers all highly liquid investments purchased with maturities at acquisition of three months or less to be cash equivalents. Cash equivalents consist of amounts invested in money market funds and tri-party reverse repurchase agreements that are collateralized by U.S. Treasury and agency securities of at least 102% of the principal amount. The Company has a policy that the collateral has at least the prevailing credit rating of U.S. Government Treasuries and Agencies. In a tri-party reverse repurchase agreement, a third-party custodian bank is used to manage the exchange of funds and ensure that collateral received is maintained of at least 102% of the value of the reverse repurchase agreements on a daily basis thereby minimizing risk and exposure to both parties. The Company does not record an asset or liability as the Company is not permitted to sell or re-pledge the associated collateral. The reverse repurchase agreements have stated maturities of 90 days or less and are included in cash equivalents due to their high liquidity and relatively low risk.

The Company holds bank accounts in the United States, the United Kingdom, Germany, Japan, China and South Korea. The Company maintains deposits in government insured financial institutions in excess of government insured limits. Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

Restricted cash relates to collateral for procurement cards issued by a U.S. commercial bank.

Software developed for internal use

The Company accounts for the costs of software obtained or developed for internal use in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 350, Intangibles – Goodwill and Other, or ASC 350. Computer software development costs are expensed as incurred, except for internal use software costs that qualify for capitalization as described below and include the cost of computer software and costs incurred in developing features and functionality. These capitalized costs are included in property and equipment, net in the condensed consolidated balance sheets. The Company expenses costs incurred in the preliminary project and post implementation stages of software development and capitalizes costs incurred in the application development stage and costs associated with significant enhancements to existing internal use software applications. Software costs are amortized using the straight-line method over estimated useful lives commencing when the software project is ready for its intended use.

Revenues

The Company’s revenues include product and service revenues. Product revenue from diagnostic test kit sales and related accessories is typically recognized at a point in time based upon the amount of consideration to which the Company expects to be entitled. For sales made with variable consideration, such as discounts, refunds, incentives, or other similar items, changes to the transaction price will be re-assessed at each reporting period until a final outcome is determined. Service revenue is recorded based upon contractually established billing rates and recognized upon delivery of test results to the customer. See Note 2. Revenue for disaggregation of revenue by geography.

For each arrangement that results in revenues, the Company first identifies all performance obligations. Then, in order to determine the transaction price, the Company estimates the amount of variable consideration at the outset of the contract either utilizing the expected value or most likely amount method, depending on the facts and circumstances relative to the contract. The Company constrains (reduces) the estimates of variable consideration such that there is only a remote possibility that a significant reversal of previously recognized revenue will occur. When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period.

For the three and six months ended June 30, 2020, the Company had no material bad-debt expense and there were no material contract assets, contract liabilities or deferred contract costs recorded on the condensed consolidated balance sheet as of June 30, 2020. The Company generally expenses sales commissions when incurred because the amortization period would be less than one year.

Revenue expected to be recognized in any future year related to remaining performance obligations is not material.

Taxes assessed by governmental authorities on revenue, including sales and value added taxes, are recorded on a net basis (excluded from revenue) in the consolidated statements of operations.

Income taxes

The Company calculates its interim income tax provision in accordance with ASC 270, Interim Reporting, and ASC 740, Accounting for Income Taxes. At the end of each interim period, the Company estimates its annual effective tax rate and applies that rate to its ordinary quarterly earnings to calculate the tax related to ordinary income. The tax effects for other items that are excluded from ordinary income are discretely calculated and recognized in the period in which they occur.

The remainder of the significant accounting estimates and policies used in preparation of the condensed consolidated financial statements disclosed in Note 1. Description of business and significant accounting policies to the consolidated financial statements in the 2019 Form 10-K remain unchanged.

Recently adopted accounting pronouncements

In January 2017, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2017-04, Intangibles – Goodwill and Other, or ASU 2017-04. ASU 2017-04 simplifies subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The Company adopted ASU 2017-04 as of January 1, 2020 on a prospective basis. The adoption of ASU 2017-04 has not had a material impact on the Company’s results of operations, financial position or related disclosures.

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, or ASU 2018-13, which modifies certain disclosure requirements on fair value measurements. The amendments regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are required to be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments are required to be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 as of January 1, 2020. The adoption of ASU 2018-13 has not had a material impact on the Company’s disclosures.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software: Customers Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, or ASU 2018-15, which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted ASU 2018-15 as of January 1, 2020 using the prospective transition approach, which allows the Company to change the accounting method without restating prior periods or recording a cumulative adjustment. The adoption of ASU 2018-15 has not had a material impact on the Company’s results of operations, financial position or related disclosures.

In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842) Codification Improvements, or ASU 2019-01, to clarify certain requirements of Accounting Standards Codification 842, Leases. The Company adopted ASU 2019-01 as of January 1, 2020. The adoption of ASU 2019-01 has not had a material impact on the Company’s results of operations, financial position or related disclosures.

Recently issued but not yet adopted accounting pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses, or ASU 2016-13. ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. Under current U.S. GAAP, a company only considered past events and current conditions in measuring an incurred loss. Under ASU 2016-13, the information that a company must consider is broadened in developing an expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss. The new guidance is to be effective for smaller reporting companies for interim and annual periods beginning after December 15, 2022. Early adoption is permitted. The guidance is applied using a modified retrospective, or prospective approach, depending on a specific amendment. The Company is currently evaluating ASU 2016-13.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, or ASU 2019-12, which includes amendments to simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC 740, Income Taxes, or ASC 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The new guidance will be effective for the Company for interim and annual periods beginning after December 15, 2020. Early adoption of the amendments is permitted. The Company is currently evaluating ASU 2019-12.

3. Fair value measurement

As a basis for determining the fair value of certain of the Company’s financial instruments, the Company utilizes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1—Observable inputs such as quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs, other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The carrying amount of certain of the Company’s financial instruments, including cash, accounts receivable, prepaid expenses and other assets, accounts payable, and accrued liabilities approximate fair value due to their short term nature.

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the entire fair value measurement requires management to make judgments and consider factors specific to the asset or liability.

The tables below present information about the Company’s financial assets measured at fair value on a recurring basis as of the respective dates and indicate the level of the fair value hierarchy utilized to determine such fair values. The Company had no financial liabilities measured at fair value on a recurring basis as of the dates indicated.

During the six-month period ended June 30, 2020, the Company issued 24,447 ordinary shares upon the exercise of options and 41,990 ordinary shares were issued upon the vesting of restricted share units, or RSUs. During the year ended December 31, 2019, the Company issued 394,078 ordinary shares upon the exercise of options and 65,405 ordinary shares were issued upon the vesting of RSUs.

In 2019, the Company’s Board of Directors authorized the repurchase of up to $100 million of its ordinary shares in the aggregate (including commissions), subject to the approval of its shareholders by an ordinary resolution at its 2019 Annual General Meeting, or the share repurchase program. The share repurchase program was approved by the Company’s shareholders at its Annual General Meeting held on June 18, 2019. The Company began repurchasing shares in September 2019. For the four month period ended December 31, 2019, the Company purchased a total of 478,856 shares for a total cost of $7.0 million. During the three-month period ended March 31, 2020, the Company repurchased 530,890 ordinary shares at a total cost of $7.7 million.

General and administrative		591			331		1,087		966
Total share-based compensation	$	610		$	846	$	1,567	$	1,691

In November 2013, in connection with the Company’s initial public offering, the Company adopted the 2013 Share Incentive Plan, or the 2013 Plan, which provides for the grant of share options, restricted shares, RSUs, and other share-based awards to employees, officers, directors and consultants of the Company. The 2013 Plan was amended at the Company’s 2017 Annual General Meeting of shareholders.

During the three-month period ended June 30, 2020, the Company granted 102,925 share options with exercise prices ranging from $10.88 to $12.96 per share under the 2013 Plan. The weighted-average grant date fair value related to share options granted under the 2013 Plan during the three-month period ended June 30, 2020 was $5.25 per share. During the six-month period ended June 30, 2020, the Company granted to certain employees and directors 450,401 share options with exercise prices ranging from $10.88 to $12.96 per share under the 2013 Plan. The weighted-average grant date fair value related to share options granted under the 2013 Plan during the six-month period ended June 30, 2020 was $5.07 per share. Share options generally vest based on the grantee’s continued service with the Company during a specified period following the vesting start date and expire after ten years.

During the three-month period ended June 30, 2020, the Company awarded 48,267 RSUs. During the six-month period ended June 30, 2020, the Company awarded 299,924 RSUs. RSUs generally vest based on the grantee’s continued service with the Company during a specified period following grant as follows: 40% on the second anniversary of the vesting start date; 30% on the third anniversary of the vesting start date; and 30% on the fourth anniversary of the vesting start date. Share-based compensation expense for these RSUs is calculated based on the grant date market price of the shares and is being recognized over the vesting period.

For the three-month period ended June 30, 2020, the Company incurred shared-based compensation expense related to share options and RSUs of $456,000 and $154,000, respectively. For the three-month period ended June 30, 2019, the Company incurred shared-based compensation expense related to share options and RSUs of $627,000 and $219,000, respectively. For the six-month period ended June 30, 2020, the Company incurred shared-based compensation expense related to share options and RSUs of $1.1 million and $475,000, respectively. For the six months ended June 30, 2019, the Company incurred shared-based compensation expense related to share options and RSUs of $1.3 million and $415,000, respectively.

As of June 30, 2020, there was $4.7 million and $5.1 million of total unrecognized compensation cost related to unvested share options and RSUs, respectively. These costs are expected to be recognized over weighted-average periods of 2.5 years for share options and 2.8 years for RSUs.

12. Leases

Operating leases

The Company has operating leases for real estate and non-real estate in the United States, United Kingdom, China, Japan, Singapore, and South Korea. One such operating lease is a sublease for real estate. The Company does not have any material finance leases.

In March 2020, the Company entered into a lease for new space in Marlborough, Massachusetts, which extends through November 2028 that will allow it to combine its warehousing and office space, currently located in Norwood, Massachusetts, with its U.S. corporate headquarters that is currently located in a separate location in Marlborough, Massachusetts, into a single facility. As of June 30, 2020, the property was not yet available for use by the Company and no right-of-use asset and corresponding lease liability were therefore recorded. The rent will commence on the earlier of the date on which the landlord delivers the property to the Company or the date on which the Company commences to operate its business in the property. The base rent on the facility over the remainder of the lease term will range from $30,000 per month to $38,000 per month.

On June 1, 2020, the Company entered into a lease extension for its property at 94C Milton Park, Abingdon U.K. The lease has been extended by a maximum of two years from the original agreement. The lease may be terminated by the Company at any time, without penalty, with three months’ notice. Annual rent during the extension period is £128,490 for January 1, 2021 to December 31, 2021, and £256,980 for January 1, 2022 to December 31, 2022.

13. Discontinued operations

In September 2018, the Company and certain of its subsidiaries entered into a Limited Liability Company Interest Purchase Agreement, or the Purchase Agreement, with Quest Diagnostics, Incorporated, or Quest, pursuant to which the Company sold its U.S. Laboratory Services Business to Quest, or the Transaction, for gross proceeds of $170 million in cash. Of this amount, approximately $32.3 million was paid directly to MidCap Financial Trust in settlement of all amounts due under the Company’s debt financing agreement, which included prepayment and exit fees of approximately $2.3 million.

At the time of sale, the U.S. Laboratory Services Business had a carrying value of $27.9 million. The Company recorded a gain of $146.0 million in connection with the Transaction, which amount was included in income from discontinued operations before income taxes in the Company’s consolidated statement of operations during the three months ended December 31, 2018.

Additionally, pursuant to the terms of the Purchase Agreement, the parties entered into certain ancillary agreements as of the Closing Date, including: (i) a transitional services agreement, or TSA, that was concluded in 2019, (ii) a technology license agreement that will remain in effect until the date of expiration or lapse of the last “Blood Stability Patent” to expire or lapse, and (iii) a long-term supply agreement, or the Supply Agreement, pursuant to which Quest agreed to purchase T-SPOT.TB test kits and related accessories. The Supply Agreement will last for a period of seven years after the effective date unless terminated earlier by a party to the Supply Agreement. In addition, the parties entered into a strategic collaboration agreement to drive continued growth of T-SPOT.TB testing in the U.S. that will remain in effect until the expiration or termination of the Supply Agreement.

For the six months ended June 30, 2020, the Company recorded a net charge from discontinued operations of $798,000 that included a correction of an immaterial prior period error of $907,000 related to a state tax assessment along with current taxes of $38,000, partially offset by a $147,000 adjustment on the remaining proceeds due from the Transaction.

During the second quarter of 2020, the Company received a payment of $4.5 million related to funds placed in escrow at the closing of the Transaction.

14. Income taxes

The Company recognized an income tax benefit of $136,000 for the three months ended June 30, 2020, representing an effective income tax rate of 1.4%. Intraperiod tax allocation rules require the Company to allocate the provision for income taxes between continuing operations and other categories of earnings, such as discontinued operations and other comprehensive income. In periods in which the Company has a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of earnings, we must allocate the tax provision to the other categories of earnings. As a result, the Company recorded a discrete expense in other comprehensive income related to unrealized gains on foreign currency translation adjustments in the U.K and a tax benefit for the three months ended June 30, 2020 through continuing operations. The Company’s effective income tax rate for the three months ended June 30, 2020 differs from the Company’s U.K statutory rate, primarily because the majority of its U.K. loss cannot be benefited due to the full valuation allowance position. The Company recorded an income tax benefit of $76,000 for the three months ended June 30, 2019.

For the six months ended June 30, 2020, the Company recognized an income tax expense of $73,000 representing an effective income tax rate of (0.5)%. The income tax expense for the six months ended June 30, 2020 was primarily related to discrete adjustments recorded in the period for an increase in valuation allowance on certain U.S state attributes and the write down of prepaid taxes, partially offset by the tax benefit recorded through continuing operations as a result of the intraperiod tax allocation rules. The Company’s effective income tax rate for the six months ended June 30, 2020 differs from the Company’s U.K statutory rate, primarily because the majority of its U.K. loss cannot be benefited due to the full valuation allowance position. The Company recorded an income tax benefit of $1.6 million for the six months ended June 30, 2019.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, was enacted in response to the COVID-19 pandemic. The CARES Act, among other provisions, permits carryovers and carrybacks of net operating losses generated in 2018 through 2020 to offset 100% of taxable income. In addition, the CARES Act allows net operating losses incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The Company continues to evaluate the impact of the CARES Act, but at present does not expect it to have a material impact on its financial statements.

Overview

We are a global, high-growth diagnostics company focused on developing and commercializing proprietary tests for immunology and infectious disease by leveraging the technological, product development, manufacturing, quality, regulatory, and sales and marketing capabilities we have developed over our seventeen year history. Our proprietary T-SPOT.TB test utilizes our T-SPOT technology platform to test for tuberculosis, which is the leading cause of infectious disease death worldwide.

We have incurred significant losses from inception and as of June 30, 2020 had an accumulated deficit of $101.3 million. Our revenue for the six months ended June 30, 2020 and 2019 was $19.7 million and $34.4 million, respectively. Our net loss for the six months ended June 30, 2020 was $15.7 million compared to a net loss of $906,000 for the six months ended June 30, 2019.

Impact of COVID-19 on our business

As the COVID-19 pandemic continues to spread and impact global populations and economies, we continue to evaluate the impact of COVID-19 on both the broad diagnostics market, and on the Company’s operations and financial condition more particularly. Given the importance of supporting patients with tuberculosis, which continues to be the leading cause of infectious disease death worldwide, we continue to diligently work with our suppliers, healthcare providers and partners to provide patients with access to our diagnostic tests, while taking into account regulatory, institutional, and government guidance, policies and protocols. COVID-19 has affected the global economy as a whole, including the economies and industries in which we operate. Uncertainties regarding the scope and impact of the outbreak of COVID-19 has caused a re-prioritization of public health activities. COVID-19 has also impacted our sales, sources of supply and operations, along with the operations of our suppliers, other partners and customers, particularly as COVID-19 protocols and resources have restricted patient access to hospitals, physicians’ offices and other testing sites. Additionally, COVID-19 has restricted our sales representatives’ access to these sites. As a result, COVID-19 has impacted our current performance and continues to represent a risk to our future performance.

The ultimate impacts of COVID-19 on our business are currently unknown and the challenges posed by COVID-19 on our business are expected to evolve rapidly. We note that the impacts from or expectations for any phasing out of restrictions may be temporary if further spread of infections requires any phasing out processes to be halted or reversed. We are actively monitoring the situation and may take precautionary and preemptive actions that we determine are in the best interests of our business. We cannot predict the effects that such actions may have on our business or on our financial results, in particular with respect to demand for our products.

Financial operations overview

Revenue

We generate revenue mainly from sales associated with our T-SPOT technology platform via our direct sales force and also through distributors. Our T-SPOT.TB test is our first commercialized product based on this technology.

We currently offer our T-SPOT.TB test as both an in vitro diagnostic kit and a service. In the former, we sell test kits and associated accessories to distributors for resale and directly to institutions and laboratories that perform tuberculosis, or TB, testing. In the latter, we have an established clinical testing laboratory in the U.K., where we perform our T-SPOT.TB test on samples sent to us by customers. For the majority of our customers, we primarily negotiate pricing directly with our customers; our prices are influenced to some degree by the mechanism and level of funding our customers receive for performing tests for TB infection.

Revenue by geography

We have a direct sales force in the U.S., certain European countries, China and Japan. Additionally, we market and sell our products through distributors in various countries, including some where we also have direct sales forces. As a result, our revenue is denominated in multiple currencies.

Second quarter revenue was significantly impacted by the COVID-19 pandemic, primarily due to a significant decline in testing demand in various countries, as responses to COVID-19 have restricted patient access to hospitals, physicians’ offices and other testing sites and caused a re-prioritization of public health activities.

The following table reflects revenue by geography (United States, Europe and rest of world, or Europe and ROW, and Asia) and as a percentage of total revenue, based on the billing address of our customers.

Sales and marketing expense

Our sales and marketing expense includes costs associated with our sales organization, including our direct sales force and sales management, and our marketing, customer service and business development personnel. These expenses consist principally of salaries, commissions, bonuses and employee benefits for these personnel, including share-based compensation, as well as travel costs related to sales, marketing costs, including the cost of obtaining marketing data, customer service activities, medical education activities and overhead expenses. We expense all sales and marketing costs as incurred.

During the three months ended June 30, 2020 and 2019, our sales and marketing expense represented 94% and 38%, respectively, of our total revenue. For the six months ended June 30, 2020 and 2019, our sales and marketing expense represented 64% and 40%, respectively, of our total revenue.

Settlement expense

Settlement expense of $104,000 for the three months ended June 30, 2019 and $203,000 for the six months ended June 30, 2019 related to the June 30, 2017 Release and Settlement Agreement with Statens Serum Institut, or SSI, or the SSI Settlement Agreement, we entered into to resolve outstanding disputes arising from a license agreement with SSI. The terms of the SSI Settlement Agreement are confidential.

Interest income

Interest income includes interest income on our available cash balances, which are primarily invested in money market funds and reverse repurchase agreements, primarily in U.S. government and agency securities, and bank savings accounts in the U.S., U.K., Germany, Japan, China and South Korea. Essentially all our cash is in the U.S. and the U.K.

Foreign exchange gains (losses)

Foreign exchange gains (losses) largely resulted from U.S. dollar denominated bank accounts, accounts receivable, and accounts payable reflected on the books of Oxford Immunotec Limited, which has a functional currency of the U.K. Pound Sterling. We are exposed to foreign exchange rate risk because we currently operate in three major regions of the world: the United States, Europe and ROW, and Asia, and our revenue is denominated in multiple currencies. Sales in the U.S. and South Korea are denominated in U.S. dollars while sales in Europe are denominated primarily in the U.K. Pound Sterling and Euro. As we grow Europe and ROW sales outside the U.K. and the Euro Zone, we may be subject to risk from additional currencies. Sales in China are denominated in Chinese Yuan. Sales in Japan are denominated in Yen.

Monetary assets and liabilities that are denominated in foreign currencies are remeasured at the period-end closing rate with resulting unrealized exchange fluctuations. Realized exchange fluctuations result from the settlement of transactions in currencies other than the functional currencies of our businesses. The functional currencies of our businesses are U.S. dollars, Pounds Sterling, Euros, Japanese Yen and Chinese Yuan, depending on the entity.

Other income (expense)

Other income (expense) includes other income and expense items.

Revenue

Revenue decreased by 70% to $5.8 million for the three months ended June 30, 2020 from $19.6 million for the same period in 2019, reflecting the impact of COVID-19.

U.S. revenue decreased by 85% to $1.2 million for the three months ended June 30, 2020 from $7.8 million for the same period in 2019, reflecting the impact of COVID-19.

Asia revenue decreased by 62% to $3.6 million for the three months ended June 30, 2020 from $9.6 million for the same period in 2019, reflecting the impact of COVID-19. On a non-generally accepted accounting principles, or non-GAAP, constant currency basis, revenue for Asia would have decreased by 63%.

Europe and ROW revenue decreased by 54% to $1.0 million for the three months ended June 30, 2020 from $2.2 million for the same period in 2019, reflecting the impact of COVID-19. On a non-GAAP constant currency basis, revenue for Europe and ROW would have decreased by 53%.

Changes in revenue include the impact of changes in foreign currency exchange rates. We use the non-GAAP financial measure “constant currency basis” in our filings to show changes in our revenue without giving effect to period-to-period currency fluctuations. Under U.S. GAAP, revenues received in local (non-U.S. dollar) currencies are translated into U.S. dollars at the average exchange rate for the period presented. When we use the term “constant currency basis”, it means that we have translated local currency revenues for the prior reporting period into U.S. dollars using the same average foreign currency exchange rates for the conversion of revenues into U.S. dollars that we used to translate local currency revenues for the comparable reporting period of the current year. We then calculate the change, as a percentage, from the prior period revenues using the current period exchange rates versus the current period revenues. This resulting percentage is a non-GAAP measure referring to a change as a percentage on a “constant currency basis”.

This non-GAAP financial measure may be different from non-GAAP financial measures used by other companies, limiting its usefulness for comparison purposes. Moreover, presentation of revenue on a constant currency basis is provided for year-over-year comparison purposes, and investors should be cautioned that the effect of changing foreign currency exchange rates has an actual effect on our operating results. We consider the use of a period over period revenue comparison on a constant currency basis to be helpful to investors, as it provides a revenue growth measure free of positive or negative volatility due to currency fluctuations.

Table of Contents

Cost of revenue and gross margin

Cost of revenue decreased by 60% to $2.2 million for the three months ended June 30, 2020 compared to the same period in 2019, due largely to decreased revenue in 2020. Gross margin for the three months ended June 30, 2020 was 63% compared to 72% for the same period in 2019.

Research and development expense

Research and development expense increased to $2.5 million for the three months ended June 30, 2020 from $2.1 million for the same period in 2019. The increase was mainly due to automation projects. As a percentage of total revenue, research and development expense was 42% for the three months ended June 30, 2020 compared to 11% for the same period in 2019.

Sales and marketing expense

Sales and marketing expense decreased to $5.5 million for the three months ended June 30, 2020 from $7.5 million for the same period in 2019. The decrease included $774,000 in salary and wages, which resulted from changes in headcount and credits for share-based compensation from departing employees, $650,000 in travel and entertainment due to COVID-19, and $447,000 for the timing of certain marketing expenses. As a percentage of total revenue, sales and marketing expense increased to 94% for the three months ended June 30, 2020 compared to 38% for the same period in 2019.

General and administrative expense

General and administrative expense increased slightly to $5.6 million for the three months ended June 30, 2020 from $5.5 million for the same period in 2019. As a percentage of total revenue, general and administrative expense increased to 95% for the three months ended June 30, 2020 from 28% for the same period in 2019.

Settlement expense

Settlement expense of $104,000 for the three-month period ended June 30, 2019 related to the Settlement Agreement with SSI to resolve outstanding disputes arising from our previous license agreement. The terms of the Settlement Agreement are confidential. There was no settlement expense for the three months ended June 30, 2020.

Interest income

Interest income was $86,000 and $1.2 million for the three months ended June 30, 2020 and 2019, respectively. Interest income declined primarily due to significantly reduced rates on our investments in U.S. Government money market funds and in tri-party reverse repurchase agreements.

Foreign exchange gains (losses)

We recorded foreign exchange losses of $124,000 for the three months ended June 30, 2020, substantially all as a net result of U.S. dollar denominated bank accounts, accounts receivable, and accounts payable reflected on the books of Oxford Immunotec Limited, which has a functional currency of the U.K. Pound Sterling. For the three months ended June 30, 2019, we recorded foreign exchange gains of $291,000. Approximately 20% of our sales for the three months ended June 30, 2020 were in the U.S., which are denominated in U.S. dollars. Sales in South Korea are also denominated in U.S. dollars. Sales in Europe are denominated primarily in the U.K. Pound Sterling and the Euro. As we grow Europe and ROW sales outside the United Kingdom and the Euro Zone, we may be subject to risk from additional currencies. Sales in China are denominated in Chinese Yuan. Sales in Japan are denominated in Yen.

Our expenses are generally denominated in the currencies in which our operations are located, which are primarily in the U.S., the U.K., Japan, Europe, China, Singapore, and South Korea.

As we continue to grow our business outside the U.S., our results of operations and cash flows will be subject to fluctuations due to changes in foreign currency exchange rates, which could harm our business in the future. To date, we have not entered into any foreign currency hedging contracts, although we may do so in the future.

Interest income

Interest income was $705,000 and$2.4 million for the six months ended June 30, 2020 and 2019, respectively. Interest income declined primarily due to significantly reduced rates on our investments in U.S. Government money market funds and in tri-party reverse repurchase agreements.

Foreign exchange gains (losses)

We recorded foreign exchange gains of $839,000 for the six months ended June 30, 2020, substantially all as a net result of U.S. dollar denominated bank accounts, accounts receivable, and accounts payable reflected on the books of Oxford Immunotec Limited, which has a functional currency of the U.K. Pound Sterling.

Our expenses are generally denominated in the currencies in which our operations are located, which are primarily in the U.S., the U.K., Japan, Europe, China, Singapore, and South Korea.

Discontinued operations

Discontinued operations relate to the U.S. Laboratory Services Business that we sold to Quest on November 6, 2018. For financial statement purposes, the results of operations for the discontinued operations were segregated from those of our continuing operations and presented in our consolidated financial statements as discontinued operations.

Liquidity and capital resources

Sources and uses of funds

Since our inception, we have incurred significant losses and negative cash flows from operations. For the six months ended June 30, 2020, we had a net loss of $15.7 million and used $9.3 million of cash for operating activities. As of June 30, 2020, we had an accumulated deficit of $101.3 million.

In 2019, our Board of Directors authorized the repurchase of up to $100 million of our ordinary shares in the aggregate (including commissions), subject to the approval of our shareholders by an ordinary resolution at our 2019 Annual General Meeting, or the share repurchase program. The share repurchase program was approved by our shareholders at our Annual General Meeting held on June 18, 2019. We began repurchasing shares in September 2019. During the three-month period ended March 31, 2020, we repurchased 530,890 shares at a total cost of $7.7 million. No shares were repurchased during the second quarter of 2020, as the share repurchase program has been paused. At June 30, 2020, $85.3 million of ordinary shares remain eligible for repurchase. The share repurchase program may be suspended, modified or terminated at any time. We have no obligation to repurchase any amount of our ordinary shares under the program. Unless terminated by our Board of Directors, the share repurchase program will be valid for up to five years from the date of inception of the program.

As of June 30, 2020, we had cash, cash equivalents, and restricted cash of $165.6 million. We maintain our available cash balances in cash, money market funds and reverse repurchase agreements primarily invested in U.S. government and agency securities, and bank savings accounts in the U.S., U.K., Germany, Japan, China and South Korea. Essentially all of our cash is in the U.S. and the U.K.

Cash flows for the six months ended June 30, 2020 and 2019

Operating activities from continuing operations

Net cash used in operating activities from continuing operations was $9.3 million during the six months ended June 30, 2020, which included a net loss from continuing operations of $14.9 million, non-cash expenses of $2.7 million, and cash provided by changes in operating assets and liabilities of $2.9 million. The non-cash items included share-based compensation expense of $1.6 million, depreciation and amortization expense of $926,000, and a provision for inventory of $455,000, partially offset by a change in deferred income taxes of $312,000. The cash provided by changes in operating assets and liabilities included a decrease in accounts receivable of $8.5 million and a decrease in prepaid expenses and other assets of $1.2 million, partially offset by a decrease in accounts payable and accrued liabilities of $3.9 million and an increase in inventory of $2.9 million. The decrease in accounts receivable reflects the decrease in sales resulting from the impact of COVID-19 and the timing of collections. The decrease in prepaid expenses and other assets reflects the timing of certain payments. The decrease in accounts payable and accrued liabilities was primarily due to lower business activity and to the timing of payments. The increase in inventory reflects timing.

Net cash used in operating activities from continuing operations was $8.2 million during the six months ended June 30, 2019, which included a net loss of $906,000, non-cash expenses of $1.1 million, and cash used for changes in operating assets and liabilities of $8.4 million. The non-cash items included share-based compensation expense of $1.7 million, depreciation and amortization expense of $900,000, and non-cash rent expense of $112,000, partially offset by credits of $1.5 million for deferred income taxes and $100,000 for non-cash interest income. The cash used for changes in operating assets and liabilities included an increase in accounts receivable of $4.7 million, an increase in inventory of $2.2 million, and an increase in prepaid expenses and other assets of $858,000, and a decrease in accounts payable and accrued liabilities of $718,000, partially offset by an increase in deferred income of $88,000. The increase in accounts receivable reflects increased revenue and timing. The increase in inventory reflects timing. The increase in prepaid expenses and other assets reflects the timing of certain payments. The decrease in accounts payable and accrued liabilities was largely due to payments in the first six months of 2019 for royalties on intellectual property and bonuses that were accrued for at December 31, 2018, as well as the timing of payments.

Investing activities from continuing operations

Net cash used in investing activities from continuing operations was $2.4 million and $520,000 during the six months ended June 30, 2020 and 2019, respectively, and consisted of purchases of property and equipment.

Financing activities from continuing operations

Net cash used in financing activities of continuing operations during the six months ended June 30, 2020 was $7.8 million and included $7.7 million used for the repurchase of our ordinary shares as permitted under the share repurchase program and $165,000 used to pay taxes withheld on exercises of options and vesting of restricted share units.

During the six months ended June 30, 2019, net cash provided by financing activities from continuing operations was $3.2 million, largely due to cash received on exercises of share options.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company’s exposure to market risk from interest rate fluctuations, capital market fluctuations, and foreign currency exchange rate fluctuations has not materially changed from its exposure as of December 31, 2019, as described in Part II, Item 7A of our 2019 Form 10-K.

Item 4. Controls and Procedures

(a)

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this Quarterly Report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to our management, including our Chief Executive and Chief Financial Officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2020 at the reasonable assurance level.

(b)

Changes in Internal Control Over Financial Reporting

There have been no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the period covered by this Quarterly Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1. Legal Proceedings

None.

Item 1A. Risk Factors

There have been no material changes in the risk factors described in Part I, Item 1A. “Risk Factors” of the 2019 Form 10-K aside from the risk factor included below:

The scale and scope of the COVID-19 pandemic is unknown and poses a significant threat to public health and infrastructure throughout the world, which could continue to have a negative impact on our business.

The global spread of COVID-19 has created significant volatility, uncertainty and economic disruption on a global scale, and particularly in geographies where we conduct a significant portion of our business, including the U.S., China, Japan and Europe. The extent to which the COVID-19 pandemic impacts our business, operations and financial results will depend on numerous evolving factors that we may not be able to accurately predict, including: the duration and scope of the pandemic; governmental, business and individuals’ actions that have been and continue to be taken in response to the pandemic; the impact of the pandemic on economic activity and actions taken in response; the effect on patients, healthcare providers and business partners; demand for, and our ability to supply, our products, including as a result of travel restrictions, social distancing, quarantines and other containment measures; the enrollment or monitoring of patients in clinical trials, along with potential delays in our research and development programs as a result of delays or interruptions in suppliers of equipment and reagents, or access to samples; the ability to obtain or deliver sufficient and timely supplies if our or our suppliers’ production capabilities are disrupted; disruptions in regulatory oversight and actions if regulators and industry professionals are expending significant and unexpected resources addressing COVID-19; the availability of coverage and reimbursement from government and health administration authorities, private health insurers and other third-party payors if the system becomes overly strained; and any closures of our and our partners’ offices, operations and facilities.

For example, we have seen a significant decline in testing demand in various countries, as COVID-19 protocols and resources have restricted patient access to hospitals, physicians’ offices and other testing sites and caused a re-prioritization of public health activities. Further, work from home policies, tailored to local rules and circumstances, have been issued by various countries for employees whose functions can be undertaken remotely. These efforts may not be as successful as traditional, in-person interactions, and are vulnerable to disruptions that may occur if the digital infrastructures are insufficient to accommodate the increased usage as social distancing is implemented on a global scale. Additionally, the COVID-19 pandemic has interrupted access by and effectiveness of our sales, marketing and medical affairs activities which will have an unknown impact on our ability to gain and maintain customers.

Also, we have been approached by certain third parties requesting that we join them in investigating the potential role of a T-cell based T-SPOT COVID-19 test. Although we are just beginning work on that subject, including with the launch of the T-SPOT Discovery SARS-CoV-2 research use only test kit, and have not yet expended significant resources pursuing such matters, any such explorations may be costly and divert resources that may have been more effectively deployed in other initiatives. Further, given the very early stages of these explorations and discussions, we cannot make any predictions or guarantees that any such explorations or discussions will progress, or result in any viable testing alternative.

In addition, essential laboratory, manufacturing and related support activities have been, and will continue to be, subject to heightened precautions to ensure safety of employees and the continuation of highest priority activities, but there is no guarantee these precautions will be adequate to prevent the spread of COVID-19 among our employees or other business disruptions. The scope and scale of COVID-19 is unprecedented and its duration and impact cannot be predicted with any certainty. Its impact could have a material and adverse impact on our revenues and operations, which could cause a decline in our stock price.

2.3	Section 6.4 is hereby added to the Purchase Agreement as follows:

“6.4 The Parties agree that for the kits sold in the RuO Field under the permission granted in Section 2.3 (iv) , the Buyer will pay to Seller ten percent (10%) of the Net Sales (as defined below) in addition to the Price paid for the Antibodies as set out in Schedule 3.

Description of business

Unaudited interim financial statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the interim condensed consolidated financial statements reflect all adjustments, of a normal recurring nature, necessary for a fair statement of the financial position at June 30, 2020, the results of operations for the three and six months ended June 30, 2020 and 2019, and the cash flows for the six-month periods ended June 30, 2020 and 2019. Interim results are not necessarily indicative of results for a full year.

The consolidated balance sheet presented as of December 31, 2019, has been derived from the Company’s audited consolidated financial statements as of that date. The consolidated financial statements and notes included in this Quarterly Report should be read in conjunction with the 2019 consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the Securities and Exchange Commission on March 6, 2020, or the 2019 Form 10-K.

Cash, cash equivalents, and restricted cash

The Company considers all highly liquid investments purchased with maturities at acquisition of three months or less to be cash equivalents. Cash equivalents consist of amounts invested in money market funds and tri-party reverse repurchase agreements that are collateralized by U.S. Treasury and agency securities of at least 102% of the principal amount. The Company has a policy that the collateral has at least the prevailing credit rating of U.S. Government Treasuries and Agencies. In a tri-party reverse repurchase agreement, a third-party custodian bank is used to manage the exchange of funds and ensure that collateral received is maintained of at least 102% of the value of the reverse repurchase agreements on a daily basis thereby minimizing risk and exposure to both parties. The Company does not record an asset or liability as the Company is not permitted to sell or re-pledge the associated collateral. The reverse repurchase agreements have stated maturities of 90 days or less and are included in cash equivalents due to their high liquidity and relatively low risk.

The Company holds bank accounts in the United States, the United Kingdom, Germany, Japan, China and South Korea. The Company maintains deposits in government insured financial institutions in excess of government insured limits. Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

Restricted cash relates to collateral for procurement cards issued by a U.S. commercial bank.

Software developed for internal use

The Company accounts for the costs of software obtained or developed for internal use in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 350, Intangibles – Goodwill and Other, or ASC 350. Computer software development costs are expensed as incurred, except for internal use software costs that qualify for capitalization as described below and include the cost of computer software and costs incurred in developing features and functionality. These capitalized costs are included in property and equipment, net in the condensed consolidated balance sheets. The Company expenses costs incurred in the preliminary project and post implementation stages of software development and capitalizes costs incurred in the application development stage and costs associated with significant enhancements to existing internal use software applications. Software costs are amortized using the straight-line method over estimated useful lives commencing when the software project is ready for its intended use.

Revenues

The Company’s revenues include product and service revenues. Product revenue from diagnostic test kit sales and related accessories is typically recognized at a point in time based upon the amount of consideration to which the Company expects to be entitled. For sales made with variable consideration, such as discounts, refunds, incentives, or other similar items, changes to the transaction price will be re-assessed at each reporting period until a final outcome is determined. Service revenue is recorded based upon contractually established billing rates and recognized upon delivery of test results to the customer. See Note 2. Revenue for disaggregation of revenue by geography.

For each arrangement that results in revenues, the Company first identifies all performance obligations. Then, in order to determine the transaction price, the Company estimates the amount of variable consideration at the outset of the contract either utilizing the expected value or most likely amount method, depending on the facts and circumstances relative to the contract. The Company constrains (reduces) the estimates of variable consideration such that there is only a remote possibility that a significant reversal of previously recognized revenue will occur. When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period.

For the three and six months ended June 30, 2020, the Company had no material bad-debt expense and there were no material contract assets, contract liabilities or deferred contract costs recorded on the condensed consolidated balance sheet as of June 30, 2020. The Company generally expenses sales commissions when incurred because the amortization period would be less than one year.

Revenue expected to be recognized in any future year related to remaining performance obligations is not material.

Taxes assessed by governmental authorities on revenue, including sales and value added taxes, are recorded on a net basis (excluded from revenue) in the consolidated statements of operations.

Income taxes

The Company calculates its interim income tax provision in accordance with ASC 270, Interim Reporting, and ASC 740, Accounting for Income Taxes. At the end of each interim period, the Company estimates its annual effective tax rate and applies that rate to its ordinary quarterly earnings to calculate the tax related to ordinary income. The tax effects for other items that are excluded from ordinary income are discretely calculated and recognized in the period in which they occur.

The remainder of the significant accounting estimates and policies used in preparation of the condensed consolidated financial statements disclosed in Note 1. Description of business and significant accounting policies to the consolidated financial statements in the 2019 Form 10-K remain unchanged.

Recently adopted accounting pronouncements

In January 2017, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2017-04, Intangibles – Goodwill and Other, or ASU 2017-04. ASU 2017-04 simplifies subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The Company adopted ASU 2017-04 as of January 1, 2020 on a prospective basis. The adoption of ASU 2017-04 has not had a material impact on the Company’s results of operations, financial position or related disclosures.

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, or ASU 2018-13, which modifies certain disclosure requirements on fair value measurements. The amendments regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are required to be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments are required to be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 as of January 1, 2020. The adoption of ASU 2018-13 has not had a material impact on the Company’s disclosures.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software: Customers Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, or ASU 2018-15, which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted ASU 2018-15 as of January 1, 2020 using the prospective transition approach, which allows the Company to change the accounting method without restating prior periods or recording a cumulative adjustment. The adoption of ASU 2018-15 has not had a material impact on the Company’s results of operations, financial position or related disclosures.

In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842) Codification Improvements, or ASU 2019-01, to clarify certain requirements of Accounting Standards Codification 842, Leases. The Company adopted ASU 2019-01 as of January 1, 2020. The adoption of ASU 2019-01 has not had a material impact on the Company’s results of operations, financial position or related disclosures.

Recently issued but not yet adopted accounting pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses, or ASU 2016-13. ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. Under current U.S. GAAP, a company only considered past events and current conditions in measuring an incurred loss. Under ASU 2016-13, the information that a company must consider is broadened in developing an expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss. The new guidance is to be effective for smaller reporting companies for interim and annual periods beginning after December 15, 2022. Early adoption is permitted. The guidance is applied using a modified retrospective, or prospective approach, depending on a specific amendment. The Company is currently evaluating ASU 2016-13.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, or ASU 2019-12, which includes amendments to simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC 740, Income Taxes, or ASC 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The new guidance will be effective for the Company for interim and annual periods beginning after December 15, 2020. Early adoption of the amendments is permitted. The Company is currently evaluating ASU 2019-12.

Significant Accounting Policies (Policies)	6 Months Ended
Significant Accounting Policies (Policies)	Jun. 30, 2020
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Unaudited interim financial statements The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the interim condensed consolidated financial statements reflect all adjustments, of a normal recurring nature, necessary for a fair statement of the financial position at June 30, 2020, the results of operations for the three and six months ended June 30, 2020 and 2019, and the cash flows for the six-month periods ended June 30, 2020 and 2019. Interim results are not necessarily indicative of results for a full year. The consolidated balance sheet presented as of December 31, 2019, has been derived from the Company’s audited consolidated financial statements as of that date. The consolidated financial statements and notes included in this Quarterly Report should be read in conjunction with the 2019 consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the Securities and Exchange Commission on March 6, 2020, or the 2019 Form 10-K.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Cash, cash equivalents, and restricted cash The Company considers all highly liquid investments purchased with maturities at acquisition of three months or less to be cash equivalents. Cash equivalents consist of amounts invested in money market funds and tri-party reverse repurchase agreements that are collateralized by U.S. Treasury and agency securities of at least 102% of the principal amount. The Company has a policy that the collateral has at least the prevailing credit rating of U.S. Government Treasuries and Agencies. In a tri-party reverse repurchase agreement, a third-party custodian bank is used to manage the exchange of funds and ensure that collateral received is maintained of at least 102% of the value of the reverse repurchase agreements on a daily basis thereby minimizing risk and exposure to both parties. The Company does not record an asset or liability as the Company is not permitted to sell or re-pledge the associated collateral. The reverse repurchase agreements have stated maturities of 90 days or less and are included in cash equivalents due to their high liquidity and relatively low risk. The Company holds bank accounts in the United States, the United Kingdom, Germany, Japan, China and South Korea. The Company maintains deposits in government insured financial institutions in excess of government insured limits. Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. Restricted cash relates to collateral for procurement cards issued by a U.S. commercial bank.
Internal Use Software, Policy [Policy Text Block]	Software developed for internal use The Company accounts for the costs of software obtained or developed for internal use in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 350, Intangibles – Goodwill and Other, or ASC 350. Computer software development costs are expensed as incurred, except for internal use software costs that qualify for capitalization as described below and include the cost of computer software and costs incurred in developing features and functionality. These capitalized costs are included in property and equipment, net in the condensed consolidated balance sheets. The Company expenses costs incurred in the preliminary project and post implementation stages of software development and capitalizes costs incurred in the application development stage and costs associated with significant enhancements to existing internal use software applications. Software costs are amortized using the straight-line method over estimated useful lives commencing when the software project is ready for its intended use.
Revenue [Policy Text Block]	Revenues The Company’s revenues include product and service revenues. Product revenue from diagnostic test kit sales and related accessories is typically recognized at a point in time based upon the amount of consideration to which the Company expects to be entitled. For sales made with variable consideration, such as discounts, refunds, incentives, or other similar items, changes to the transaction price will be re-assessed at each reporting period until a final outcome is determined. Service revenue is recorded based upon contractually established billing rates and recognized upon delivery of test results to the customer. See Note 2. Revenue for disaggregation of revenue by geography. For each arrangement that results in revenues, the Company first identifies all performance obligations. Then, in order to determine the transaction price, the Company estimates the amount of variable consideration at the outset of the contract either utilizing the expected value or most likely amount method, depending on the facts and circumstances relative to the contract. The Company constrains (reduces) the estimates of variable consideration such that there is only a remote possibility that a significant reversal of previously recognized revenue will occur. When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period. For the three and six months ended June 30, 2020, the Company had no material bad-debt expense and there were no material contract assets, contract liabilities or deferred contract costs recorded on the condensed consolidated balance sheet as of June 30, 2020. The Company generally expenses sales commissions when incurred because the amortization period would be less than one year. Revenue expected to be recognized in any future year related to remaining performance obligations is not material. Taxes assessed by governmental authorities on revenue, including sales and value added taxes, are recorded on a net basis (excluded from revenue) in the consolidated statements of operations.
Income Tax, Policy [Policy Text Block]	Income taxes The Company calculates its interim income tax provision in accordance with ASC 270, Interim Reporting, and ASC 740, Accounting for Income Taxes. At the end of each interim period, the Company estimates its annual effective tax rate and applies that rate to its ordinary quarterly earnings to calculate the tax related to ordinary income. The tax effects for other items that are excluded from ordinary income are discretely calculated and recognized in the period in which they occur. The remainder of the significant accounting estimates and policies used in preparation of the condensed consolidated financial statements disclosed in Note 1. Description of business and significant accounting policies to the consolidated financial statements in the 2019 Form 10-K remain unchanged.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently adopted accounting pronouncements In January 2017, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2017-04, Intangibles – Goodwill and Other, or ASU 2017-04. ASU 2017-04 simplifies subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The Company adopted ASU 2017-04 as of January 1, 2020 on a prospective basis. The adoption of ASU 2017-04 has not had a material impact on the Company’s results of operations, financial position or related disclosures. In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, or ASU 2018-13, which modifies certain disclosure requirements on fair value measurements. The amendments regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are required to be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments are required to be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 as of January 1, 2020. The adoption of ASU 2018-13 has not had a material impact on the Company’s disclosures. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software: Customers Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, or ASU 2018-15, which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted ASU 2018-15 as of January 1, 2020 using the prospective transition approach, which allows the Company to change the accounting method without restating prior periods or recording a cumulative adjustment. The adoption of ASU 2018-15 has not had a material impact on the Company’s results of operations, financial position or related disclosures. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842) Codification Improvements, or ASU 2019-01, to clarify certain requirements of Accounting Standards Codification 842, Leases. The Company adopted ASU 2019-01 as of January 1, 2020. The adoption of ASU 2019-01 has not had a material impact on the Company’s results of operations, financial position or related disclosures. Recently issued but not yet adopted accounting pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses, or ASU 2016-13. ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. Under current U.S. GAAP, a company only considered past events and current conditions in measuring an incurred loss. Under ASU 2016-13, the information that a company must consider is broadened in developing an expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss. The new guidance is to be effective for smaller reporting companies for interim and annual periods beginning after December 15, 2022. Early adoption is permitted. The guidance is applied using a modified retrospective, or prospective approach, depending on a specific amendment. The Company is currently evaluating ASU 2016-13. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, or ASU 2019-12, which includes amendments to simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC 740, Income Taxes, or ASC 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The new guidance will be effective for the Company for interim and annual periods beginning after December 15, 2020. Early adoption of the amendments is permitted. The Company is currently evaluating ASU 2019-12.
