Quidel Corporation
Notes to Consolidated Financial Statements
(Unaudited)
Note 1. Summary of Significant Accounting Policies
Basis of Presentation
The accompanying unaudited consolidated financial statements of Quidel Corporation and its subsidiaries (the “Company”) have been prepared in accordance with generally accepted accounting principles in the United States (“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 GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation (consisting of normal recurring accruals) have been included.
The information at September 30, 2017,March 31, 2020, and for the three and nine months ended September 30, 2017March 31, 2020 and 2016,2019, is unaudited. For further information, refer to the Company’s consolidated financial statements and notes thereto for the year ended December 31, 20162019 included in the Company’s 20162019 Annual Report on Form 10-K. Operating results for any quarter are historically seasonal in nature and are not necessarily indicative of the results expected for the full year.
For 20172020 and 2016,2019, the Company’s fiscal year will end or has ended on January 3, 2021 and December 31, 2017 and January 1, 2017,29, 2019, respectively. For 20172020 and 2016,2019, the Company’s thirdfirst quarter ended on October 1, 2017March 29, 2020 and October 2, 2016,March 31, 2019, respectively. For ease of reference, the calendar quarter end dates are used herein. The three and nine monththree-month periods ended September 30, 2017March 31, 2020 and 20162019 each included 13 and 39 weeks, respectively.
Comprehensive Loss
Comprehensive loss includes foreign currency translation adjustments excluded from the Company’s Consolidated Statements of Operations.weeks.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires the Companymanagement to make estimates and judgmentsassumptions that affect the reported amounts of assets and liabilities revenues and expenses, and related disclosuredisclosures of contingent assets and liabilities. On an on-going basis, management evaluates its estimates, including those related to customer programsliabilities at the date of the financial statements and incentives, bad debts, inventories, intangible assets, income taxes, stock-based compensation, contingenciesthe reported amounts of revenues and litigation. Management bases its estimates on historical experience and on various other assumptions that it believes are reasonable underexpenses during the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.reporting period. Actual results maycould differ from thesethose estimates.
Revenue RecognitionSignificant Accounting Policies
The Company records revenues primarily from product sales. These revenues are recorded net of rebates and other discounts. These rebates and discounts are estimated atDuring the time of sale, and are largely driven by various customer program offerings, including special pricing agreements, promotions and other volume-based incentives. Revenues from product sales are recorded upon passage of title and risk of lossthree months ended March 31, 2020, there have been no changes to the customer. Passage of title to the product and recognition of revenue occurs upon delivery to the customer when sales terms are freeour significant accounting policies as described in our Annual Report on board (“FOB”) destination and at the time of shipment when the sales terms are FOB shipping point and there is no right of return.
A portion of product sales includes revenues for diagnostic kits, which are utilized on leased instrument systems under the Company’s “reagent rental” program. The reagent rental program provides customers the right to use the instruments at no separate cost to the customer in consideration for a multi-year agreement to purchase annual minimum amounts of consumables (“reagents” or “diagnostic kits”). When an instrument is placed with a customer under a reagent rental agreement, the Company retains title to the equipment and it remains capitalized on the Company’s Consolidated Balance Sheets as property and equipment. The instrument is depreciated on a straight-line basis over the life of the instrument. Depreciation expense is recorded in cost of sales included in the Consolidated Statements of Operations. The reagent rental agreements represent one unit of accounting as the instrument and consumables (reagents) are interdependent in producing a diagnostic result and neither has a stand-alone value with respect to these agreements. No revenue is recognized at the time of instrument placement. All revenue is recognized when the title and risk of lossForm 10-K for the diagnostic kits have passed to the customer.fiscal year ended December 31, 2019.

Royalty revenue from the grant of license rights is recognized during the period in which the revenue is earned and the amount is determinable from the licensee.
The Company earns income from grants for research and commercialization activities. On November 6, 2012, the Company was awarded a milestone-based grant totaling up to $8.3 million from the Bill and Melinda Gates Foundation to develop, manufacture and validate a quantitative, low-cost, nucleic acid assay for HIV drug treatment monitoring on the integrated Savanna MDx platform for use in limited resource settings. Upon execution of the grant agreement, the Company received $2.6 million to fund subsequent research and development activities and received milestone payments totaling $2.5 million in 2013. On September 10, 2014, the Company entered into an amended grant agreement with the Bill and Melinda Gates Foundation for additional funding of up to $12.6 million in order to accelerate the development of the Savanna MDx platform in the developing world. Upon execution of the amended grant agreement, the Company received $10.6 million in cash. The Company received payments of $2.4 million in April 2015 and $2.8 million in July 2016 based on milestone achievements for both the original and the amended grant agreements. Under the original and amended grant agreements, the Company recognized grant revenue on the basis of the lesser of the amount recognized on a proportional performance basis or the amount of cash payments that were non-refundable as of the end of each reporting period. The Company recognized $3.8 million and $6.5 million as grant revenue for the three and nine months ended September 30, 2016, respectively. Cash payments received were restricted as to use until expenditures contemplated in the grant were incurred or committed. As of September 30, 2016 all payment related milestones were achieved and all of the grant revenue of $20.9 million was fully recognized. As such, the Company recognized no grant revenue during the nine months ended September 30, 2017.
Fair Value Measurements
The Company uses the fair value hierarchy established in Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, whichrequires that the valuation of assets and liabilities subject to fair value measurements be classified and disclosed by the Company in one of the following three categories:
Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity).
The carrying amounts of the Company’s financial instruments, including cash, receivables, accounts payable and accrued liabilities approximate their fair values due to their short-term nature.
Reclassifications
The Company recorded immaterial reclassifications of acquisition and integration costs totaling $0.2 million and $0.6 million for three and nine months ended September 30, 2016, respectively, from general and administrative expense as previously reported in the Consolidated Statements of Operations to conform to current year presentation. The Company believes these reclassifications provide greater clarity and insight into the consolidated financial statements for the periods presented. The reclassification did not impact the net loss as previously reported or any prior amounts reported on the Consolidated Balance Sheets, Statements of Cash Flows or Statements of Comprehensive Loss.
Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance codified in Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, which amends the guidance in former ASC 605, Revenue Recognition (“ASU 2014-09”). The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under current authoritative guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The FASB has issued several amendments to the new standard, which include clarification of accounting guidance related to identification of performance obligations, intellectual property licenses and principal vs. agent

considerations. The standard will be effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods therein.
The Company has assigned internal resources to assist in the adoption of the new standard and is evaluating the impact of the new standard on its accounting policies, processes and system requirements. The Company has begun the process of identifying, categorizing and analyzing its various revenue streams, but has not yet completed its assessment of the impact. The Company will continue to evaluate the future impact and method of adoption of ASU 2014-09 and related amendments on the Consolidated Financial Statements and related disclosures throughout the remainder of 2017. The Company will adopt the new standard beginning January 2018.
In February 2016, the FASB issued guidance codified in ASU 2016-02 (Topic 842), Leases. The guidance requires a lessee to recognize a lease liability for the obligation to make lease payments and a right-to-use asset representing the right to use the underlying asset for the lease term on the balance sheet. The guidance is effective for fiscal years beginning after December 15, 2018 including interim periods therein, with early adoption permitted. The Company is currently evaluating the impact of this guidance and expects to adopt the standard in the first quarter of 2019.
In March 2016, the FASB issued guidance codified in ASU 2016-09 (Topic 718), Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). This guidance includes provisions to simplify several aspects of accounting for share-based payment transactions, including income tax consequences, accounting for forfeitures, classification of awards as either equity or liability and classification on the statement of cash flows. ASU 2016-09 includes a requirement that the tax effect related to the settlement of share-based awards be recorded within income tax expense or benefit in the income statement. The simplification of income tax accounting for share-based payment transactions also impacts the computation of weighted-average diluted shares outstanding under the treasury stock method. The Company adopted ASU 2016-09 in the first quarter of 2017 and the impact of the adoption resulted in the following:
Upon adoption, the balance of the unrecognized excess tax benefits of $1.8 million was recorded as an increase to deferred tax assets and a corresponding increase to the valuation allowance, resulting in no impact to retained earnings.
Excess tax benefits from share-based arrangements are to be classified within cash flow from operating activities, rather than as cash flow from financing activities. The Company applied this provision on a retrospective basis and the prior period statement of cash flows was adjusted. This adoption did not have a material impact on the Company’s cash flows.
The Company elected to continue to estimate the number of awards expected to be forfeited and adjust the estimate when appropriate, as is currently required. This adoption did not have a material impact on the Company’s consolidated results of operations, financial condition or cash flows.
There was no material impact on the computation of weighted-average diluted shares outstanding.

In January 2017, the FASB issued guidance codified in ASU 2017-04, Intangibles-Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). Under this new guidance, an entity will no longer determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Instead, an entity will compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The guidance is effective for fiscal years beginning after December 15, 2019 including interim periods therein, with early adoption permitted. The Company is currently evaluating the impact of this guidance and expects to adopt the standard in the first quarter of 2020.
Note 2. Computation of Earnings (Loss) Per Share
Basic earnings (loss) per share (“EPS”) is computed by dividing net earnings (loss)income by the weighted-average number of common shares outstanding, including restricted stock units (“RSUs”) vested during the period. Diluted earnings per share (“EPS”)EPS is computed based on the sum of the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of shares issuable from stock options, unvested RSUs and the 3.25% Convertible Senior Notes due 2020 (“Convertible Senior Notes”). Potentially dilutive common shares from outstanding stock options and unvested RSUs are determined using the average share price for each period under the treasury stock method. As discussed in Note 6, it isPotentially dilutive shares from the Company’s intent and policy to settle conversions through combination settlement, which essentially involves repayment of an amount of cash equal toConvertible Senior Notes are determined using the “principal portion” and deliveryif-converted method. Under the provisions of the “share amount”if-converted method, the Convertible Senior Notes are assumed to be converted and included in excessthe denominator of the conversion value overEPS calculation and the principal portioninterest expense, net of tax, recorded in cash or shares of common stock (“conversion premium”). connection with the Convertible Senior Notes is added back to net income.
The Convertible Senior Notes have a dilutive impact when the average market price of the Company’s common stock exceeds the applicable conversion price of the notes. The Senior Convertible Notes became convertible on March 31, 2018 and remained convertible through March 31, 2020.

Potentially dilutive shares excluded from the calculation above represent stock options when the combined exercise price and unrecognized stock-based compensation are greater than the average market price for the Company’s common stock because their effect is anti-dilutive.
Additionally, the number of potentially dilutive shares issuable under the stock options, RSUs and Convertible Senior Notes that would have been included in the diluted EPS calculation if the Company had earnings amounted to 1.8 million and 1.2 million for the three and nine months ended September 30, 2017, respectively. The number of stock options and RSUs that would have been included in the diluted EPS calculation if the Company had earnings amounted to 0.9 million and 0.8 million for the three and nine months ended September 30, 2016, respectively. No conversion premium existed on the Convertible Senior Notes as of September 30, 2016; therefore, there was no dilutive impact from the Convertible Senior Notes to diluted EPS during the three and nine months ended September 30, 2016.

Note 5.4. Income Taxes
The Company calculates its interim income tax provision in accordance with Accounting Standards Codification (“ASC”) 270, Interim Reporting, and ASC 740, Accounting for Income Taxes (together, “ASC 740”). 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 Company recognized income tax expenseprovisions of $0.2$8.6 million and an income tax benefit of $0.3$1.7 million for the three months ended September 30, 2017March 31, 2020 and 2016,2019, respectively. The Company recognized income tax expense of $0.4 million and an income tax benefit of $7.1 million for the nine months ended September 30, 2017 and 2016, respectively. For the three and nine months ended September 30, 2017, the Company recorded income tax expense compared to an income tax benefit in the same periods of 2016 as no tax benefit was provided for losses incurred in United States Federal and certain state jurisdictions

because those losses are offset by a full valuation allowance and the Company has recorded tax expense for foreign jurisdictions and certain state jurisdictions during this time period.
In interim periods when a small change in forecasted information results in a significant change to the estimated annualCompany’s 18% effective tax rate for the three months ended March 31, 2020 and the income tax expense or benefit for an interim period, a discrete6% effective tax rate method may provide a more reliable estimate than applyingfor the annual effective taxthree months ended March 31, 2019 differed from the federal statutory rate methodof 21% primarily due to the year-to-date loss. The discrete methodimpact of calculatingexcess tax deductions from stock-based compensation, the Company's estimated effective tax ratebenefit from research and income tax expense ordevelopment (“R&D”) credits and the benefit uses actual results for the interim period(s), instead of forecasted information. For the third quarter of 2017, the Company used the discrete effective tax rate methodfrom corporate deductions attributable to calculate the income tax expense.Foreign Derived Intangible Income (“FDII”).
The Company is subject to periodic audits by domestic and foreign tax authorities. Due to the carryforward of unutilized net operating loss and credit carryovers,credits, the Company'sCompany’s federal tax years from 2009 and forward are subject to examination by the U.S. authorities. The Company'sCompany’s state and foreign tax years for 2001 and forward are subject to examination by applicable tax authorities. The Company believes that it has appropriate support for the income tax positions taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors, including past experience and interpretations of tax laws applied to the facts of each matter.
The Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted on March 27, 2020. The CARES Act includes, among other things, refundable payroll tax credits, deferment of employer side social security payments and technical amendments regarding the income tax depreciation of qualified improvement property placed in service after December 31, 2017. These amendments allow for retroactive accelerated income tax depreciation on certain of our leasehold improvement assets. We are currently assessing the impact of these provisions to our financial statements.
Note 6.5. Debt

Convertible Senior Notes
In December 2014, the Company issued $172.5 million aggregate principal amount of its 3.25% Convertible Senior Notes. Debt issuance costs of approximately $5.1 million were primarily comprised of underwriters fees, legal, accounting and other professional fees, of which $4.2 million were capitalized and are recorded as a reduction to long-term debt and are being amortized using the effective interest method to interest expense over the six-year term of the Convertible Senior Notes. The remaining $0.9 million of debt issuance costs were allocated as a component of equity in additional paid-in capital. Deferred issuance costs related toThe implied interest rate of the Convertible Senior Notes were $2.3 million and $2.8 million as of September 30, 2017 andwas 6.9%, assuming no conversion option. The Convertible Senior Notes mature on December 31, 2016, respectively.15, 2020.
The Convertible Senior Notes will beare convertible into cash, shares of common stock, or a combination of cash and shares of common stock based on an initial conversion rate, subject to adjustment, of 31.1891 shares per $1,000 principal amount of the Convertible Senior Notes (which represents an initial conversion price of approximately $32.0632.06 per share). The conversion will occur in the following circumstances and to the following extent: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2015, if the last reported sales 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 notes in effect
10


on each applicable trading day; (2) during the five5 consecutive business day period following any five5 consecutive trading day period in which the trading price per $1,000 principal amount of the Convertible Senior Notes for each such trading day was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such day; or (3) upon the occurrence of specified events described in the indenture for the Convertible Senior Notes. On or after September 15, 2020 until the close of business on the second scheduled trading day immediately preceding the stated maturity date, holders may surrender their notes for conversion at any time, regardless of the foregoing circumstances.
It is the Company’s intent and policy to settle conversions through combination settlement, which essentially involves repayment of an amount of cash equal to the “principal portion” and delivery of the “share amount” in excess of the principal portion in shares of common stock or cash. In general, for each $1,000 in principal, the “principal portion” of cash upon settlement is defined as the lesser of $1,000, or the conversion value during the 25-day observation period as described in the indenture for the Convertible Senior Notes. The conversion value is the sum of the daily conversion value, which is the product of the effective conversion rate divided by 25 days and the daily volume weighted-average price (“VWAP”) of the Company’s common stock. The “share amount” is the cumulative “daily share amount” during the observation period, which is calculated by dividing the daily VWAP into the difference between the daily conversion value (i.e., conversion rate x daily VWAP) and $1,000.
The Company pays 3.25% interest per annum on the principal amount of the Convertible Senior Notes semi-annually in arrears in cash on June 15 and December 15 of each year. The Convertible Senior Notes mature on December 15, 2020. During the nine months ended September 30, 2017 and 2016, the Company recorded total interest expense of $8.2 million related to the Convertible Senior Notes, of which $4.1 million related to the amortization of the debt discount and issuance costs and $4.1 million related to the coupon due semi-annually.

If a fundamental change, as defined in the indenture for the Convertible Senior Notes, such as an acquisition, merger or liquidation of the Company, occurs prior to the maturity date, subject to certain limitations, holders of the Convertible Senior Notes may require the Company to repurchase all or a portion of their Convertible Senior Notes for cash at a repurchase price equal to 100% of the principal amount of the Convertible Senior Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the repurchase date.
The Company accounts separately forDuring the liability and equity componentsfirst quarter of 2020, the last reported sales price of the Company’s common stock was greater than 130% of the Convertible Senior Notes in accordance with authoritative guidanceconversion price for 20 or more of the 30 consecutive trading days preceding the quarter-end. Consequently, the Convertible Senior Notes were convertible debt instruments thatas of March 31, 2020. If the Convertible Senior Notes were converted as of March 31, 2020, the if-converted amount would exceed the principal by $0.6 million. The Convertible Senior Notes may be settled at the Company’s option in cash upon conversion. or a combination of cash and shares of common stock.
The guidance requiresCompany pays 3.25% interest per annum on the carryingprincipal amount of the liability component to be estimated by measuringConvertible Senior Notes semi-annually in arrears in cash on June 15 and December 15 of each year. During the fair value of a similar liability that does not have an associated conversion feature. Becausethree months ended March 31, 2020, the Company had no outstanding non-convertible public debt, the Company determined that senior, unsecured corporate bonds traded on the market represent a similar liabilityrecorded total interest expense of $0.2 million related to the Convertible Senior Notes, withoutof which $0.1 million related to the conversion option. Based on market data available for publicly traded, senior, unsecured corporate bonds issued by companies inamortization of the same industry with similar credit ratingsdebt discount and with similar maturity,issuance costs and $0.1 million related to the coupon due semi-annually. During the three months ended March 31, 2019, the Company estimated the impliedrecorded total interest rateexpense of its Convertible Senior Notes to be 6.9%, assuming no conversion option. Assumptions used in the estimate represent what market participants would use in pricing the liability component, which were defined as Level 2 observable inputs. The estimated implied interest rate was applied$1.0 million related to the Convertible Senior Notes of which resulted in a fair value$0.5 million related to the amortization of the liability component of $141.9 million upon issuance, calculated as the present value of implied future payments based on the $172.5 million aggregate principal amount. The $30.7 million difference between the cash proceeds of $172.5 million and the estimated fair value of the liability component was recorded in additional paid-in capital, net of taxdebt discount and issuance costs as the Convertible Senior Notes were not considered redeemable.
During the nine months ended September 30, 2016, the Company repurchased and retired $5.2 million in principal amount of the outstanding Convertible Senior Notes. The aggregate cash used for the transaction was $4.5 million. The repurchase resulted in a reduction in debt of $4.4 million and a reduction in additional paid-in capital of $0.5 million with a gain on extinguishment of Convertible Senior Notes of $0.4 million included in interest expense, net inrelated to the Consolidated Statements of Operations.

As a policy election under applicable guidance related to the calculation of diluted net EPS, the Company elected the combination settlement method as its stated settlement policy and applied the treasury stock method in the calculation of dilutive impact of the Convertible Senior Notes. The Convertible Senior Notes were not convertible as of September 30, 2017 and 2016; therefore there was no dilutive impact during the three and nine months ended September 30, 2017 and 2016. If the Convertible Senior Notes were converted as of September 30, 2017, the if-converted value would not exceed the principal amount.

Senior Credit Agreement
On October 6, 2017,August 31, 2018, the Company entered into aan Amended and Restated Credit Agreement (the “Credit Agreement”), which providedprovides the Company with a $245.0$175.0 million senior secured term loan facility (the “Term Loan”) and a $25.0 million revolving credit facility (the “Revolving Credit Facility”), together (the “Senior Credit Facility”). The Term Loan and the Revolving Credit Facility will mature on October 6, 2022. On the closing date of the Credit Agreement, the Company borrowed the entire

amount of the Term Loan and $10.0 million under the Revolving Credit Facility. The Company used the proceedsThere is no balance outstanding as of the Term Loan along with its cash on hand, to pay (i) the consideration for the cardiovascular and toxicology Triage® MeterPro business (“Triage Business”) and (ii) the fees and expenses incurred in connection with the acquisition of the Triage Business and the Triage® BNP Test for the Beckman Coulter Access Family of Immunoassay Systems (the “BNP Business”). See Note 12 for further discussion of the acquisition of the Triage Business and BNP Business.
March 31, 2020. The Credit Agreement includes an accordion feature that allows the facility to be increased by $50.0 million upon the satisfactionhas a term of certain conditions. The Financing is guaranteed by certain material domestic subsidiaries of the Company (the “Guarantors”)five years and is secured by liensmatures on substantially all of the assets of the Company and the Guarantors, excluding real property and certain other types of excluded assets. If the Company does not consummate a sale leaseback transaction with respect to the Summers Ridge property acquired as part of the Triage Business within 180 days of the closing of the Credit Agreement, the Company will also be required to grant the Lenders a mortgage on the real property associated with the Summers Ridge property.August 31, 2023.
Loans under the Credit Agreement will bear interest at a rate equal to (i) the London Interbank Offered Rate (“LIBOR”) plus the “applicable rate” or (ii) the “base rate” (defined as the highest of (a) the Bank of America prime rate, (b) the Federal Funds rate plus one-half of one percent and (c) LIBOR plus one1 percent) plus the “applicable rate.” The initial applicable rate will be 2.50%was 1.00% per annum for base rate loans and 3.50%2.00% per annum for LIBOR rate loans, and thereafter will be determined in accordance with a pricing grid based on the Company’s Consolidated Leverage Ratio (as defined in the Credit Agreement) ranging from 2.50%1.75% to 3.50%2.50% per annum for LIBOR rate loans and from 1.50%0.75% to 2.50%1.50% per annum for base rate loans. In addition, the Company will paypays a commitment fee on the unused portion of the Credit Agreement based on the Company’s Consolidated Leverage Ratio ranging from 0.10%0.15% to 0.50%0.30% per annum.
The Term LoanCredit Agreement is subject to quarterly amortization of the principal amount on the last business day of each fiscal quarterguaranteed by certain material domestic subsidiaries of the Company (commencing(the “Guarantors”) and is secured by liens on March 30, 2018) in such amounts as are set forth insubstantially all of the Credit Agreement. The Term Loanassets of the Company and the Revolving Credit Facility will mature on October 6, 2022, provided that if any of the Company’s 3.25% Convertible Senior Notes due 2020 (the “Convertible Senior Notes”) remain outstanding on the date that is 91 days prior to the maturity date of the Convertible Senior NotesGuarantors, excluding real property and the Company has not satisfied certain Refinancing Conditions (as defined in the Credit Agreement), then the maturity date for the Term Loan and the Revolving Credit Facility will be the date that is 91 days prior to the maturity date of the Convertible Senior Notes.
The Company must prepay loans outstanding under the Credit Agreement in an amount equal to 50% of Excess Cash Flow (as defined in the Credit Agreement) for each fiscal year (commencing with fiscal 2018) less any amount voluntarily prepaid during such fiscal year, but only if the Consolidated Senior Secured Leverage Ratio (as defined in the Credit Agreement) as of the last day of such fiscal year is greater than or equal to 1.25 to 1.00. The Company must also prepay loans outstanding under the Credit Agreement in an amount equal to 100% of the Net Cash Proceeds (as defined in the Credit Agreement) from (i) certain property dispositions and (ii) the receipt of certain other amounts not in the ordinary coursetypes of business, in each case, if not reinvested within a specified time period as contemplated in the Credit Agreement,excluded assets, and with a carve out of up to 30% of the Net Cash Proceeds of the contemplated sale leaseback transaction relating to the Company’s Summers Ridge property to the extent the excluded amounts are used for specified purposes.
The Credit Agreement contains affirmative and negative covenants that are customary for credit agreements of this
11


nature. The negative covenants include, among other things, limitations on asset sales, mergers, indebtedness, liens, dividends and other distributions, investments and transactions with affiliates. The Credit Agreement contains two2 financial covenants: (i) a maximum Consolidated Leverage Ratio (as defined in the Credit Agreement) as of the last day of each fiscal quarter for the most recently completed four fiscal quarters of (a) 5.00 to 1.00 for the fiscal quarter ending December 31, 2017, (b) 4.25 to 1.00 for the fiscal quarters ending March 31, 2018 through December 31, 2018 and (c) 3.50 to 1.00, for the fiscal quarter ending March 31, 2019 and each fiscal quarter thereafter;which ratio may be increased to 4.50 to 1.00 in case of certain qualifying acquisitions; and (ii) a minimum Consolidated Fixed Charge Coverage Ratio (as defined in the Credit Agreement) of 1.25 to 1.00 as of the end of any fiscal quarter for the most recently completed four fiscal quarters. The Company was in compliance with all financial covenants as of March 31, 2020. 
Interest expense recognized under the Credit Agreement, including amortization of deferred issuance cost, was $0.2 million for the three months ended March 31, 2020 and $0.6 million for the three months ended March 31, 2019.

Note 9.8. Commitments and Contingencies
LegalLeases
We lease administrative, research and development, sales and marketing and manufacturing facilities and certain equipment under various non-cancelable lease agreements. Facility leases generally provide for periodic rent increases, and may contain clauses for rent escalation, renewal options or early termination.
Summers Ridge Lease The Company leases 3 of the 4 buildings that are located on the Summers Ridge Property in San Diego, California with an initial term through January 2033 with options to extend the lease for 2 additional five-year terms upon satisfaction of certain conditions, which have not been included in the determination of the lease term. The lease is subject to must-take provisions related to one additional building, which will have the same lease term as the three buildings originally leased. The remaining building is subject to the expiration of the lease with its current tenant for which the expiration date is not yet known.
As a result of the relocation of the Company’s headquarters to the Summers Ridge Property, the Company entered into a sublease of its former headquarters building in January 2020, with minimum rent of $2.4 million under the sublease agreement. Lease income for the three months ended March 31, 2020 was $0.1 million.
McKellar Court Lease — In 1999, the Company completed a sale and leaseback transaction of its San Diego facility at McKellar Court to a partnership for which the Company is a 25% limited partner. The partnership is deemed to be a variable interest entity (VIE). The Company is not, however, the primary beneficiary of the VIE as it does not have the power to direct the activities of the partnership and does not have the obligation to absorb losses or receive benefits of the partnership that could potentially be significant to the partnership. The McKellar Court lease ends in December 2020 and contains options to extend the lease for 3 additional five-year periods, of which one five-year period is included in the determination of the lease term.
Litigation and Other Legal Proceedings
In Beckman Coulter Inc. v. Quidel Corporation, which was filed in the Superior Court for the County of San Diego, California, on November 27, 2017, Beckman Coulter (“Beckman”) alleges that a provision of an agreement between Quidel and Beckman violates state antitrust laws. Our acquisition of the B-type Naturietic Peptide assay business (“BNP Business”) consisted of assets and liabilities relating to a contractual arrangement with Beckman (the “Beckman Agreement”) for the supply of antibodies and other inputs related to, and distribution of, the Triage® BNP Test for the Beckman Coulter Access Family of Immunoassay Systems. The Beckman Agreement further provides that Beckman, for a specified period, cannot research, develop, manufacture or sell an assay for use in the diagnosis of cardiac diseases that measures or detects the presence or absence of BNP or NT-pro-BNP (a related biomarker) (the “Exclusivity Provision”). In the lawsuit, Beckman asserts that this provision violates certain state antitrust laws and is unenforceable. Beckman contends that it has suffered damages due to this provision and seeks a declaration that this provision is void.
On December 7, 2018, the trial court granted a motion by Beckman for summary adjudication, holding that the Exclusivity Provision is void under California law (the “December 7 Order”). On December 18, 2018, the trial court stayed the effect of the December 7 Order pending a decision on a writ petition Quidel intended to file with the Court of Appeal. Quidel filed its writ petition on January 18, 2019, asking the Court of Appeal to review and reverse the December 7 Order. On February 7, 2019, the trial court stayed all the remaining litigation pending the outcome of the writ petition and vacated all deadlines in the case.
On March 14, 2019, the Court of Appeal issued an order to show cause why the relief sought in Quidel’s petition should not be granted. The Court also stayed the December 7 Order pending a further order from the Court of Appeal. On August 29, 2019, the Court of Appeal issued a written decision ruling in Quidel’s favor and overturning the December 7 Order. Beckman challenged the Court of Appeal’s ruling with a petition for rehearing on September 10, 2019, which was denied on September 13, 2019.
On October 1, 2019, Beckman filed a petition for review of the Court of Appeal’s ruling with the Supreme Court of California (the “Supreme Court”). We subsequently filed an answer to Beckman’s petition, Beckman filed a response to our reply and on November 13, 2019, the Supreme Court granted review of the Court of Appeal ruling, with further action in this matter being deferred pending consideration and disposition of a related issue in Ixchel Pharma v. Biogen, or pending further order of the Supreme Court.

On November 22, 2019, the trial court continued the stay at the trial court level and scheduled a status conference for December 11, 2020.
Quidel denies that the Exclusivity Provision is unlawful, denies any liability with respect to this matter, and intends to vigorously defend itself. There are multiple factors that prevent us from being able to estimate the amount of loss, if any, that may result from this matter including: (1) we are vigorously defending ourselves and believe that we have a number of meritorious legal defenses; (2) there are unresolved questions of law and fact that could be important to the ultimate resolution of this matter, some of which are subject to review by the Supreme Court; and (3) discovery is ongoing. Accordingly, at this time, we are not able to estimate a possible loss or range of loss that may result from this matter or to determine whether such loss, if any, would have a material adverse effect on our financial condition, results of operations or liquidity.
From time to time, the Company is involved in variousother litigation and proceedings, including matters related to product liability claims, commercial disputes and litigationintellectual property claims, as well as regulatory, employment, and other claims related to our business. The Company accrues for legal claims when, and to the extent that, amounts associated with the claims become probable and are reasonably estimable. The actual costs of resolving legal claims may be substantially higher or lower than the amounts accrued for those claims. For those matters from timeas to time inwhich we are not able to estimate a possible loss or range of loss, we are not able to determine whether the ordinary courseloss will have a material adverse effect on our business, financial condition or results of business. operations or liquidity. No accrual has been recorded as of December 31, 2019 and December 31, 2018 related to such matters as they are not probable and/or reasonably estimable.
Management believes that all such current legal actions, in the aggregate, will not have a material adverse effect on the Company. However, the resolution of, or increase in any accruals for, one or more matters may have a material adverse effect on the Company’s results of operations and cash flows.
The Company also maintains insurance, including coverage for product liability claims, in amounts whichthat management believes are appropriate given the nature of its business. No accruals have been recorded as of September 30, 2017 or as of December 31, 2016 related to such matters as they are not probable and/or reasonably estimable.
Licensing Arrangements
The Company has entered into various licensing and royalty agreements, which largely require payments by the Company based on specified product sales as well as the achievement of specified milestones. The Company had royalty and license expenses relating to those agreements of approximately $0.2 million and $0.1 million for the three months ended September 30, 2017 and 2016, respectively. The Company had royalty and license expenses relating to those agreements of approximately $0.5 million and $0.6 million for the nine months ended September 30, 2017 and 2016, respectively.
Research and Development Agreements
The Company has entered into various research and development agreements that provide it with rights to develop, manufacture and market products using the intellectual property and technology of its collaborative partners. Under the terms of certain of these agreements, the Company is required to make periodic payments based on achievement of certain milestones or resource expenditures. These milestones generally include achievement of prototype assays, validation lots and clinical trials. As of September 30, 2017 and December 31, 2016, total future commitments under the terms of these agreements are estimated at $0.4 million and $2.3 million, respectively. The commitments will fluctuate as the Company agrees to new phases of development under the existing arrangements.

The Company used Level 1 inputs to determine the fair value of its cashCash equivalents which primarily consist of funds held in government money market accounts that are valued using quoted prices in active markets for identical instruments. Derivative financial instruments are measured based on observable inputs that are corroborated by market data. Observable inputs include broker quotes and commercial paper. As such,daily market foreign currency rates and forward pricing curves. 
In connection with the carryingacquisition of the BNP Business, the Company pays annual installments of $40.0 million each in deferred consideration through April 2023 and up to $8.0 million each in contingent consideration through April 2022. The fair

value of the deferred consideration is calculated based on the net present value of cash equivalents approximates fair value. During the third quarter of 2017, the Company converted all cash equivalents to cash, and therefore, had no cash equivalents as of September 30, 2017. As of December 31, 2016, the carrying value of cash equivalents was $133.5 million.
In conjunction with the acquisitions of BioHelix Corporation in May 2013, AnDiaTec GmbH & Co. KG in August 2013 and Immutopics, Inc. in March 2016, the Company has recorded contingent consideration of $4.7 million as of September 30, 2017 and $5.2 million as of December 31, 2016.payments using an estimated borrowing rate based on a quoted price for a similar liability. The Company assessesrecorded $1.9 million for the accretion of interest on the deferred consideration during the three months ended March 31, 2020. The fair value of contingent consideration to be settled in cash related to acquisitionsis calculated using a discounted revenueprobability weighted valuation model. Significant assumptions used in the measurement include revenue projections and discount rates. This fair value measurement of contingent consideration is based on significant inputsrates that are not observed in the market and thus represent Level 3 measurements. The discount rate of 4.0% used as of March 31, 2020 was based on estimated borrowing rate for a similar liability.

Note 11. Acquisition10. Derivatives and Hedging
On May 16, 2017In the normal course of business, the Company acquiredis exposed to gains and losses resulting from fluctuations in foreign currency exchange rates. As part of its strategy to manage the InflammaDry®level of exposure to the risk of fluctuations in foreign currency exchange rates, the Company uses designated cash flow hedges in the form of foreign currency forward contracts to mitigate the impact of foreign currency translation on transactions that are denominated primarily in the Euro and AdenoPlus® diagnostic businesses from RPS Diagnostics (“RPS”), a developerthe Chinese Yuan. The Company also uses non-designated forward contracts to hedge non-functional currency denominated balance sheet assets. All hedging relationships for all designated derivative hedges and manufacturerthe underlying hedged items, as well as the risk management objectives and strategies for undertaking the hedge transactions, are formally documented. The duration of rapid, point-of-care (“POC”) diagnostic teststhese forward contracts are generally less than one year. The Company does not use any derivative financial instruments for trading or other speculative purposes.
Such forward foreign currency contracts are carried at fair value in prepaid expenses and other current assets or other current liabilities depending on the eye health and primary care markets, for approximately $13.7 million in cash. The purchase price has been preliminarily allocated as follows: $6.1 million to purchased technology and $7.6 million to goodwill. The acquisition has been accounted for in conformity with ASC Topic 805, Business Combinations. The InflammaDry and AdenoPlus products are rapid, lateral-flow based, POC products for the detection of infectious and inflammatory diseases and conditionsunrealized gain or loss position of the eye. Revenues for these products are reflectedhedged contract as of the balance sheet date.

Acquisitioncredit or market loss. Credit risk represents our gross exposure to potential accounting loss on derivative instruments that are outstanding or unsettled if all counterparties failed to perform according to the terms of Triage and BNP Businesses
On October 6, 2017, the Company acquired the Triage Business and BNP Business from Alere Inc. In connectioncontract, based on then-current currency exchange rates at each respective date. We generally enter into master netting arrangements, which reduces credit risk by permitting net settlement of transactions with the acquisitionsame counterparty. We present our derivative assets and derivative liabilities at their net fair values. We did not have any derivative instruments with credit-risk related contingent features that would require us to post collateral.
The following table summarizes the fair value and notional amounts of the Triage Business, the Company paid $400.0 million in cash (subject to certain inventory related adjustments set forth in the Amendeddesignated and Restated Triage Purchase Agreement)non-designated foreign currency forward contracts as of March 31, 2020 and assumed certain liabilities. These acquisitions significantly enhance the Company's revenue profile and expands the Company's geographic and product diversity. The Company used proceeds from the Term Loan of $245.0 million and cash on hand to pay (i) the consideration for the Triage Business and (ii) fees and expenses incurred in connection with the acquisition of the Triage Business and BNP Business. In connection with the acquisition of the BNP Business, the Company will: (i) pay (subject to certain inventory related adjustments set forth in the Amended and Restated BNP Purchase Agreement) (A) up to $40.0 million in cash, payable in five annual installments of $8.0 million, the first of which will be paid on April 30, 2018, and (B) $240.0 million in cash, payable in six annual installments of $40.0 million each, the first of which will be paid on April 30, 2018; and (ii) assume certain liabilities.

In addition, we intend to continue to evaluate candidates for new product lines, company or technology acquisitions or technology licensing. If we decide to proceed with any such transactions, we may need to incur additional debt or issue additional equity, to successfully complete the transactions.
Our primary source of liquidity, other than our holdings of cash and cash equivalents, has been cash flows from operations.operations and financing. Cash generated from operations provides us with the financial flexibility we need to meet normal operating, investing and financing needs. We anticipate that our current cash and cash equivalents, together with cash provided by operating activities will be sufficient to fund our near termnear-term capital and operating needs for at least the next 12 months. As such, we have not applied for and do not anticipate needing to apply for any loans under the Paycheck Protection Program (the “PPP”), which was established under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”).
Normal operating needs include the planned costs to operate our business, including amounts required to fund working capital and capital expenditures. Our primary short-term needs for capital, which are subject to change, include expenditures related to:
support of commercialization efforts related to our current and future products, including support of our direct sales force and field support resources both in the United Statesresources;
interest on and abroad;
repayments of our Convertible Senior Notes, Senior Credit Facilitydeferred consideration, contingent consideration and lease obligations;
the continued advancement of research and development efforts;
acquisitions of equipment and other fixed assets for use in our current and future manufacturing and research and development facilities; and
the integration of our recent strategic acquisitions and investments; and
potential strategic acquisitions and investments.
In December 2014, we issuedOur Convertible Senior Notes due in the aggregate principal amount of $172.5 million. The Convertible Senior Notes2020 have a coupon rate of 3.25% and are due 2020.

We expect our revenue and operating expenses will significantly impact our cash management decisions. Our future capital requirements and the adequacy of our available funds to service our long-term debt and to fund working capital expenditures and business development efforts will depend on many factors, including:
our ability to successfully integrate our recently acquired businesses and realize revenue growth from our new technologies and create innovative products in our markets;
our outstanding debt and covenant restrictions;
leveragingour ability to leverage our operating expenses to realize operating profits as we grow revenue;
competing technological and market developments; and
the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings.

The major contributors to the use of cash during the nine months ended September 30, 2016 were a$32.9 million reflected net loss $11.9 million, a change in deferred tax assets and liabilitiesincome of $7.4$24.8 million and non-cash adjustments of $18.5 million associated with depreciation, amortization, stock-based compensation and accretion of interest on deferred consideration. Partially offsetting these inflows was a net working capital use of $9.7cash of $11.2 million. Offsetting this use of cash was the add back of non-cash items of $27.7 million related to depreciation, amortization and stock based compensation.
Our investing activities used $27.2$5.9 million during the ninethree months ended September 30, 2017March 31, 2020 primarily related to payments for the acquisition of the InflammaDry and AdenoPlus diagnostic businesses from RPS, as more fully described in Note 11 in the Notes to the Consolidated Financial Statements for approximately $13.7 million. Additionally, we used $12.8 million on productioncomputer equipment, building improvements, Sofia, Solana and SolanaTriage instruments available for lease and intangible assets.manufacturing equipment.

In addition, we used cash for investing activities associated with the acquisitionpurchase of production equipment, building improvementsand Sofia, Solana and Sofia and SolanaTriage instruments availableavailable for lease.
We are currently planning approximately $5.0 $40 million in capital expenditures forfor the remainder of 2017.2020. The primary purpose for our capital expenditures is to acquire Sofia, Solana and Triage instruments, to acquire manufacturing and scientific equipment, to purchase or develop information technology Sofia and Solana instruments and to implement facility improvements. We plan to fund these capital expenditures with the cash on our balance sheet.
Cash provided by financing activities was $14.1$0.7 million during the ninethree months ended September 30, 2017 and wasMarch 31, 2020 primarily related to proceeds from the issuance of common stock of $15.2$2.8 million from stock option exercises, partially offset by the repurchases of common stock of $0.5 million and payments on acquisition-related contingencies of $0.5$2.0 million.

Seasonality
Sales of our infectious diseaserespiratory products are subject to, and significantly affected by, the seasonal demands of the cold and flu seasons, prevalent during the fall and winter. As a result of these seasonal demands, we typically experience lower sales volume in the second and third quarters of the calendar year, and typically have higher sales in the first and fourth quarters of the
21


calendar year. Historically, sales of our infectious diseaserespiratory products have varied from year to year based, in large part, on the severity, length and timing of the onset of the cold and flu seasons.season. Although the impact of COVID-19 on our business is still uncertain, there are early indications that COVID-19 may have some seasonality to its prevalence that could also impact the sales of our respiratory products from quarter to quarter.
Off-Balance Sheet Arrangements
At September 30, 2017March 31, 2020 and December 31, 2016,2019, we did not have any relationships with unconsolidated entities or financial partners, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.
Recent Accounting Pronouncements
Information about recently adopted and proposed accounting pronouncements is included in Note 1 of the Notes to Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report under the heading “Recent Accounting Pronouncements” and is incorporated by reference herein.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosuredisclosures of contingent assets and liabilities. On an on-going basis, management evaluates its estimates, including those related to customer programsrevenue recognition, goodwill and incentives, bad debts, inventories, intangible assets,intangibles, business combinations and income taxes, stock-based compensation, contingencies and litigation.taxes. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
A comprehensive discussion of our critical accounting policies and management estimates is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2016.2019. There were no material changes to our critical accounting policies and estimates during the three months ended March 31, 2020.
ITEM 3. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
We are not subject to interest rate risk on our Convertible Senior Notes as the notesNotes have a fixed interest rate.rate of 3.25%. For fixed rate debt, changes in interest rates will generally affect the fair value of the debt instrument, but not our earnings or cash flows. Under our current policies, we do not use interest rate derivative instruments to manage our exposure to changes in interest rates.
Our current investment policy with respect to our cash and cash equivalents focuses on maintaining acceptable levels of interest rate risk and liquidity. Although we periodicallycontinually evaluate our placement of investments, as of September 30, 2017, we did not have anyMarch 31, 2020, our cash and cash equivalents were placed in funds held inthe Company’s highly liquid operating accounts as well as government money market accounts and commercial paper.accounts.
Foreign Currency Exchange Risk
The majority
We are exposed to foreign currency risks that arise from normal business operations. These risks include the translation of local currency balances of foreign subsidiaries, transaction gains and losses associated with intercompany loans with foreign subsidiaries and transactions denominated in currencies other than a location’s functional currency.
22


During the three months ended March 31, 2020, total revenues increased 18% to $174.7 million, of which approximately $25.2 million in revenue was denominated in currencies other than the U.S. dollar. On a constant currency basis, revenue growth during the three months ended March 31, 2020 was also 18%. We believe constant currency and constant currency growth rate enhance the comparison of our international sales are negotiatedfinancial performance from period-to-period, and to that of our competitors. Constant currency revenue excludes the impact from foreign currency fluctuations, which was an unfavorable $0.5 million for the three months ended March 31, 2020, and paid in U.S. dollars. Nonetheless, these sales are subject to currency risks, since changesis calculated by translating current period revenues using prior period exchange rates, net of any hedging effect recognized in the valuescurrent period. Constant currency revenue growth (expressed as a percentage) is calculated by determining the change in current period constant currency revenues over prior period revenues.
The major currencies to which our revenues are exposed are the Euro and the Chinese Yuan. A 100-basis point move in the average exchange rates (assuming a simultaneous and immediate 100 basis point change for the relevant period) would have resulted in an increase or decrease in our reported revenue for the three months ended March 31, 2020 as follows (in thousands):

The Company has a foreign currency management policy in place that permits the use of foreign currencies relativederivative instruments, such as forward contracts, to the valuereduce volatility in our results of the U.S. dollar can render our products comparatively more expensive. Theseoperations resulting from foreign exchange rate fluctuations could negatively impact international sales of our products, as could changes in the general economic conditions in those markets. Continued change in the values of the Euro, the Japanese Yen and other foreign currencies could have an impact on our business, financial condition and results of operations.fluctuations. We do not currently hedge against exchange rate fluctuations, which means that we are fully exposed to exchange rate changes. In

ITEM 4. Controls and Procedures
Evaluation of disclosure controls and procedures: We have performed an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”). Based on that evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of September 30, 2017March 31, 2020 at a reasonable assurance level to ensure that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
Changes in internal control over financial reporting: There was no change in our internal control over financial reporting during the quarter ended September 30, 2017March 31, 2020 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

The novel coronavirus (COVID-19) global pandemic could adversely affect our business operations, financial performance and results of operations, the extent of which is uncertain and difficult to predict.
In late 2019, a detailed descriptionnovel strain of coronavirus (COVID-19) was reported to have surfaced in Wuhan, China, which has since spread globally. In March 2020, the World Health Organization declared COVID-19 a global pandemic. Further, the

Table of Contents
COVID-19 outbreak has resulted in government authorities throughout the United States and around the world implementing numerous measures to try to reduce the spread of COVID-19, such as travel bans and restrictions, quarantines, shelter in place or total lock-down orders and business limitations and shutdowns. As a result of the COVID-19 outbreak and the related responses from government authorities, our business operations, financial performance and results of operations may be adversely impacted in a number of ways, including, but not limited to, the following:
a slowdown or stoppage in the supply chain of the raw materials and packaging used to manufacture our products;
interruptions or delays in global shipping to transport and deliver our products to our distributors and customers;
interruptions in normal operations of certain end use customers that could result in reductions in demand for non-COVID-19 related healthcare operations and testing;
disruptions to our operations, including a shutdown of one or more of our facilities or product lines; restrictions on our operations and sales, marketing and distribution efforts; and interruptions to our research and development, manufacturing, clinical/regulatory and other important business activities;
shutdown or interruption of one or more of our manufacturing facilities due to contamination and costs incurred to clean and disinfect a facility following contamination;
inefficiencies and increased costs in our production and shipping processes due to premium pay for manufacturing and certain other employees as well as social distancing and personal protective equipment requirements;
delays in operations arising from limitations in the availability of personal protective equipment and clean room equipment and supplies for certain of our manufacturing personnel;
limitations on employee resources and availability, including due to sickness, government restrictions, the desire of employees to avoid contact with large groups of people or mass transit disruptions;
an increase in cyber-attacks given our public profile as a manufacturer of SARS-CoV-2 products;
a fluctuation in foreign currency exchange rates or interest rates could result from market uncertainties;
an increase in the cost or the difficulty to obtain debt or equity financing;
an increase in exposure to credit losses for customers adversely affected by the COVID-19 pandemic;
an increase in regulatory restrictions or continued market volatility could hinder our ability to execute strategic business activities, including acquisitions; and
negatively impact our stock price.
The spread of COVID-19 has caused us to modify our business practices (including employee travel, employee work locations, and cancellation of physical participation in meetings, events and conferences), and we may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, customers, partners, and suppliers. There is no certainty that such measures will be sufficient to mitigate the risks posed by the virus, and our ability to perform critical functions could be harmed.
We are continuing to rapidly and significantly expand our manufacturing capacity, including expanding and scaling our infrastructure to support our COVID-19 test products. This rapid expansion can place significant strain on our management, personnel, operations, systems and financial resources. Failure to successfully manage this expansion could negatively affect our operating results, including due to inefficiencies in implementing such expansion or higher costs for materials, technology, equipment and personnel during the intensity of the COVID-19 pandemic. Moreover, we may not realize the revenue growth and profitability we anticipate for our COVID-19 and other respiratory diagnostic products, which could result, among other factors, in a failure to realize the benefits of our manufacturing capacity expansion and the value of those investments being written down or written off.

Additionally, COVID-19 could negatively affect our internal controls over financial reporting as a portion of our workforce is required to work from home and therefore new processes, procedures, and controls could be required to respond to changes in our business environment. Further, should any key employees become ill from COVID-19 and unable to work, the attention of the management team could be diverted.
The effects of COVID-19 may exacerbate our other risk factors refer to Part II, Item 1A, “Risk Factors,” of our Quarterly Reports on Form 10-Q for the periods ended September 30, 2017 and June 30, 2017 anddiscussed in in Part I, Item 1A, “RiskRisk Factors,” of in our Annual Reportreport on Form 10-K for the year ended December 31, 2016.
Our acquisition of Alere’s Triage® and BNP businesses may present certain risks to our business and operations.
On On October 6, 2017, we acquired the Triage Business and the BNP Business from Alere, Inc. The acquisition of these businesses, and the transition and integration process related thereto, present certain risks to our business and operations, including, among other things, risks that:
we may be unable to successfully transition and integrate the businesses, and we may experience business interruptions during transition and integration;
we may not realize the anticipated benefits of the acquisitions, including those anticipated to arise from reducing costs, making product and process improvements and developing new products;
we may lose management personnel and other key employees and be unable to attract and retain such personnel and employees;
management's attention and our other  resources may be focused on integration activities instead of on day-to-day management activities, including pursuing other beneficial opportunities;
we may incur substantial unexpected integration or transition related costs;
the deferred consideration payable to Alere for the BNP Business will be payable even if BNP sales are significantly reduced, or even terminate, whether as a result of the introduction of a competing product or otherwise, and such payment obligations may significantly exceed the revenues from such business;
we may not be able to successfully or efficiently manage our foreign expansion, and the acquired businesses will increase our exposure and risks related to foreign markets;
we may be subject to claims, litigation, other legal proceedings and liabilities and damages in connection with the businesses and assets acquired in the acquisitions, some of which may not be covered in full, if at all, by the indemnification provisions provided for in the acquisition agreements, and even if indemnified, may be disruptive to our business;

we may not be able to receive required regulatory approvals or clearances relating to the acquired businesses, the acquired products, or may lose previously received regulatory approvals or clearances;
in certain international markets, the marketing authorizations to sell the acquired products will continue to be held by Alere post-closing until the authorizations can be transferred to us through the applicable regulatory process, and such deferred closings have additional risks, including:
we may not timely receive such authorizations, if at all, or may encounter unexpected difficulties and costs in receiving the authorizations;
we may have less control over the acquired businesses until the deferred closings;
completion of the acquisitions may trigger assignment or other provisions in certain commercial contracts to which Alere was a party, such that counterparties may potentially have the right to terminate the contracts; and
launching branding or rebranding initiatives may involve substantial costs and may not be favorably received by customers.
Alere may fail to perform under various transition agreements that were executed as part of our acquisition of the Triage Business and the BNP Business and we may fail to have necessary systems and services in place when certain of the transition agreements expire.
In connection with the acquisition of the Triage Business and the BNP Business, we entered into a number of agreements with Alere, including transition services agreements and a manufacturing and supply agreement. Certain of these agreements will provide for the performance of services by each company for the benefit of the other for a period of time after the closing of the acquisitions of the Triage Business and the BNP Business. If Alere is unable or unwilling to satisfy its payment or performance obligations under these agreements, we could incur operational difficulties or losses which could have a material adverse effect on our profitability and business. In addition, if the costs that we must pay for the services under these agreements significantly increase this could affect our profitability. Moreover, if we do not have our own systems and services in place, or if we do not have agreements in place with other providers of these services when the term of a particular transition service terminates (whether at the end of the term or as a result of an early termination), we may not be able to operate our business effectively, and the cost of such systems and services may be greater than what is provided under the transition services.
As we build our information technology infrastructure and transition the Triage Business and BNP Business to the Company’s own systems, we could incur substantial additional costs and experience temporary business interruptions.
We are installing and implementing information technology infrastructure to support critical business functions relating to the Triage Business and BNP Business, including accounting and reporting, customer service, inventory control and distribution, billing and receivables collection, as well as order entry, warehousing, and other administrative services. Under the transition services agreements with Alere, Alere is required to provide services both inside and outside the United States, including back office services, for up to two years following the closings of the acquisitions of the Triage Business and BNP Business. The services provided include information technology, billing and receivables collection, as well as order entry, warehousing, and certain other administrative services. These transition services agreements allow the Company to operate the Triage Business and BNP Business prior to establishing its back office infrastructure and information technology systems to accommodate the Triage Business and BNP Business. The Company’s failure to avoid operational interruptions as it implements the new systems and information technology could disrupt its integration of the Triage Business and the BNP Business and have a material adverse effect on its profitability.
Risk Factors Related to our Indebtedness
Our substantial debt could materially adversely affect our financial condition and results of operations.
On October 6, 2017, we entered into a $270.0 million five-year senior secured credit facility (the “Senior Credit Facility”), consisting of a $245.0 million Term Loan, all of which was borrowed at the closing, and a $25.0 million Revolving Credit Facility, $10.0 million of which was borrowed at the closing. The Senior Credit Facility includes an accordion feature that allows the borrowings under the Senior Credit Facility to be increased by $50 million upon the satisfaction of certain conditions. See Note 6 of the Notes to the Consolidated Financial Statements for a more detailed description of the Credit Agreement. We also have outstanding indebtedness under our Convertible Senior Notes described in Note 6 of the Notes to the Consolidated Financial Statements, and may incur other indebtedness from time to time.
2019. The degree to which we are leveraged could have important consequences to our potential and current investors, including:
our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions and general corporate purposes may be impaired;

a significant portion of our cash flow from operating activities must be dedicated to the payment of our debt, which reduces the funds available to us for our operations and may limit our ability to engage in acts that may be in our long-term best interests;
some of our debt is and will continue to be at variable rates of interest, which may result in higher interest expense in the event of increases in market interest rates;
our debt agreements may contain, and any agreements to refinance our debt likely will contain, financial and restrictive covenants, and our failure to comply with them may result in an event of default which if not cured or waived, could have a material adverse effect on us;
our level of indebtedness will increase our vulnerability to, and reduce our flexibility to respond to, general economic downturns and adverse industry and business conditions;
as our long-term debt ages, we may need to renegotiate or repay such debt or seek additional financing;
to the extent the debt we incur requires collateral to secure such indebtedness, our assets could be at risk and our flexibility related to such assets could be limited;
our debt service obligations could limit our flexibility in planning for, or reacting to, changes inCOVID-19 impacts our business and industry; and
our level of indebtedness may place us at a competitive disadvantage relative to less leveraged competitors.
We may not be able to generate sufficient cash flow to meet our debt service obligations, and any inability to repay our debt when due would have a material adverse effect on our business,operations, financial conditionperformance and results of operations.
Our ability to generate sufficient cash flow from operating activities to make scheduled or other required payments on our debt obligations and maintain a desired level of capital expenditures depends on our future performance, which is subject to economic, financial, competitive and other factors, many of which are beyond our control. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to undertake these activities may also be restricted by the terms of our various debt instruments then in effect. In addition, our ability to refinance our indebtedness or issue additional equity capitaloperations will depend on future developments, which are highly uncertain, continuously evolving and cannot be predicted, including, but not limited to, the capital marketsduration and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. Any such default on our debt obligations could materially adversely affect our business, financial condition and results of operations.
The Senior Credit Facility is secured by substantially all of our assets and those of our subsidiary guarantors.
Borrowings under the Senior Credit Facility are guaranteed by certain of our material domestic subsidiaries and are secured by liens on substantially all of our assets and thosespread of the guarantor subsidiaries, other than real propertyCOVID-19 outbreak, its severity, the actions to contain the virus or treat its impact, how quickly and certain other types of excluded assets. Under the Senior Credit Facility, the Company is required to use commercially reasonable efforts to effect a sale leaseback transaction with respect to its Summers Ridge property (the “Summers Ridge Sale Leaseback”). If we cannot effect such Summers Ridge Sale Leaseback within 180 days of the closing of the Senior Credit Facility, we must grant a security interest in that property as additional collateral for the Senior Credit Facility. If we default under our secured indebtedness, including our Senior Credit Facility, the holders of such debt could proceed against the collateral securing that indebtedness, which could materially adversely affect our business, financial conditionwhat extent normal economic and results of operations.
The Senior Credit Facility contains certain prepayment requirements that will limit our ability to use our cash flow from operationsoperating conditions can resume and the proceeds of certain assets sales or other monies for other corporate purposes.
Subject to certain limitations, the Company is required to prepay loans outstanding under the Senior Credit Facility out of its excess cash flow and out of the net cash proceeds of property dispositions and certain other amounts received not in the ordinary course of business, such as certain insurance proceeds and condemnation awards. For example, the Company is required to use a substantial portion of the proceeds of the Summers Ridge Sale Leaseback to repay amounts under the Senior Credit Facility. These requirements to prepay the Senior Credit Facility with excess monies will limit the flexibility of the Company to utilize those monies for other purposes that may be in the best interests of the Company.
Borrowings under the Senior Credit Facility will be accelerated if certain conditions are not met prior to the maturity of the Convertible Senior Notes.
Although the regular maturity date for the Senior Credit Facility is October 6, 2022, the maturity will be accelerated and all borrowings under the Senior Credit Facility will become due and payable on the date that is 91 days prior to the maturity of the Convertible Senior Notes, if any of the Convertible Senior Notes remain outstanding on that date and certain liquidity and

refinancing conditions are not satisfied. If the Senior Credit Facility is accelerated under this provision, the Company may not be able to refinance the facility on acceptable terms, and could be forced to sell assets or issue stock in order to obtain money to repay the Senior Credit Facility. Any failure to repay the Senior Credit Facility when due would have a material adverse effect on the Company and its liquidity and financial position.
The agreements relating to our indebtedness contain terms that restrict our ability to operate our business, and as a result may materially adversely affect our results of operations.
Our Senior Credit Facility contains,residual economic and other effects. Because this situation continues to evolve globally, the ultimate impacts to us of our debt agreements may include from time to time, a number of restrictive covenants that impose significant operating and financial restrictions on us and our subsidiaries. Such restrictive covenants significantly limit our ability to:
incur additional debt, including guarantees;
allow other liens on our property;
make certain investments and acquisitions;
sell or otherwise dispose of assets;
engage in mergers or consolidations or allow a change in control to occur;
make distributions to our stockholders;
engage in restructuring activities;
enter into transaction with affiliates;
prepay or amend other indebtedness;
engage in certain sale and leaseback transactions; and
issue or repurchase stock or other securities.
Such agreements also require us to satisfy other requirements, including maintaining certain financial ratios. Our ability to meet these requirements can be affected by events beyond our control and we may be unable to meet them. To the extent we fail to meet anyCOVID-19 are uncertain, but such requirements and are in default under our debt obligations, our financial condition may be materially adversely affected. These restrictions may limit our ability to engage in activities that could otherwise benefit us. To the extent that we are unable to engage in activities that support the growth, profitability and competitiveness of our business, our results of operations may be materially adversely affected.
An event of default under any agreement relating to our outstanding indebtedness or other event that could require outstanding debt to be prepaid or purchased by the Company could cross default other indebtedness, whichimpacts could have a material adverse effect on our business, financial condition and results of operations.
If there were an event of default under any of the agreements relating to our outstanding indebtedness, the holders of the defaulted debt could cause all amounts outstanding with respect to that debt to be due and payable immediately, which default or acceleration of debt could cross default other indebtedness. Our Senior Credit Facility could also be cross defaulted as a result of other events that could require outstanding indebtedness to be prepaid or purchased by the Company. Any cross default with respect to any of our indebtedness would put immediate pressure on our liquidityperformance and financial condition and would amplify the risks described above with regards to being unable to repay our indebtedness when due and payable. We cannot assure you that our assets or cash flow would be sufficient to fully repay borrowings under our outstanding debt instruments if accelerated upon an event of default, and, as described above, any inability to repay our debt when due would have a material adverse effect on our business, financial condition and results of operations.condition.
If interest rates increase, our debt service obligations under our variable rate indebtedness could increase significantly, which would have a material adverse effect on our results of operations.
Borrowings under certain of our facilities from time to time, including under our Senior Credit Facility, are at variable rates of interest and as a result expose us to interest rate risk. If interest rates were to increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. To the extent the risk materializes and is not fully mitigated, the resulting increase in interest expense could have a material adverse effect on our results of operations.
