(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Business
Exact Sciences Corporation (together with its subsidiaries, “Exact,” or the “Company”) was incorporated in February 1995. Exact is a leading global cancer diagnostics company. It has developed some of the most impactful brands in cancer screening and diagnostics, including Cologuard® and Oncotype DX®. Exact is currently working on the development of additional tests, for other types of cancer, with the goal of bringing new, innovative cancer tests to patients throughout the world.
Basis of Presentation and Principles of Consolidation
The accompanying condensed consolidated financial statements, which include the accounts of Exact Sciences Corporation and those of its wholly owned subsidiaries and variable interest entities, are unaudited and have been prepared on a basis substantially consistent with the Company’s audited financial statements and notes as of and for the year ended December 31, 20192020 included in the Company’s Annual Report on Form 10-K (the “2019“2020 Form 10-K”). All intercompany transactions and balances have been eliminated upon consolidation. These condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and follow the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. In the opinion of management, the accompanying unaudited condensed financial statements contain all adjustments (consisting only of adjustments of a normal and recurring nature) considered necessary for a fair statement of its financial position, operating results and cash flows for the periods presented. The condensed consolidated balance sheet at December 31, 20192020 has been derived from audited financial statements, but does not contain all of the footnote disclosures from the 20192020 Form 10-K. The results of the Company’s operations for any interim period are not necessarily indicative of the results of the Company’s operations for any other interim period or for a full fiscal year. The statements should be read in conjunction with the audited financial statements and related notes included in the 20192020 Form 10-K.
Use of Estimates
The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Critical accounting policies are those that affect the Company’s financial statements materially and involve difficult, subjective or complex judgments by management, and actual results could differ from those estimates. These estimates include revenue recognition, valuation of convertible notes, valuation of intangible assets and goodwill, and accounting for income taxes among others. The Company’s critical accounting policies and estimates are explained further in the notes to the condensed consolidated financial statements in this Quarterly Report and the 20192020 Form 10-K.
The spread of the coronavirus (“COVID-19”) has affected many segments of the global economy, including the cancer screening and diagnostics industry. The COVID-19 outbreak, which the World Health Organization has classified as a pandemic, has prompted governments and regulatory bodies throughout the world to issue “stay-at-home” or similar orders, and enact restrictions on the performance of “non-essential” services, public gatherings and travel. Health systems, including key markets where the Company operates, have been, or may be, overwhelmed with high volumes of patients suffering from COVID-19.
Due to social distancing, stay-at-home orders, and other actions taken in response to COVID-19, there has been a significant and widespread decline in standard wellness visits and preventive medical services. That decline has negatively impacted Cologuard test orders in the Company’s Screening business, notwithstanding the availability of alternative ordering channels such as telehealth. The Company expects that Cologuard orders and revenues will lag in the second quarter of 2020 and beyond.

The Precision Oncology business is also starting to see weakening underlying conditions because of COVID-19, more notably in the U.S. prostate business and in certain international geographies. The Company’s expects the widespread decrease in preventive services, such as mammograms and prostate cancer screenings, to negatively impact Precision Oncology test volumes in the coming months due to the typical lag between cancer screening and genomic test ordering.
The extent to which COVID-19 impacts the Company’s business and financial results will depend on numerous evolving factors including, but not limited to: the magnitude and duration of COVID-19, the extent to which it will impact worldwide macroeconomic conditions including interest rates, employment rates and health insurance coverage, the speed of the anticipated recovery, access to capital markets, and governmental and business reactions to the pandemic. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of March 31, 20202021 and through the date of the filing of this report.Quarterly Report on Form 10-Q. The accounting matters assessed included, but were not limited to, the Company’s allowance for doubtful accounts and credit losses, equity investments, software, and the carrying value of the goodwill and other long-lived assets. The Company’s future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in additional material impacts to the Company’s consolidated financial statements in future reporting periods.
CashThe pandemic and Cash Equivalentsrelated precautionary measures began to materially disrupt the Company's operations in March 2020 and may continue to disrupt the business for an unknown period of time. As a result, the pandemic impacted the Company's revenues and operating results for the three months ended March 31, 2021.

Marketable Securities
Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Debt securities carried at amortized cost are classified as held-to-maturity whenmitigate its public health effects. As a result, the Company hasis unable to estimate the positive intent and abilityextent to hold the securities to maturity. Debt securities not classified as held-to-maturity are classified as available-for-sale. Available-for-sale securities are carried at fair value. The unrealized gains and losses, net of tax, on the Company’s debt securities are reported in other comprehensive income. Marketable equity securities are measured at fair value and the unrealized gains and losses, net of tax, are recognized in other income (expense) in the condensed consolidated statements of operations. The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretion of discounts to maturity computed under the straight-line method. Such amortization is included in investment income, net. Realized gains and losses and declines in value as a result of credit losses on available-for-sale securities are included in investment income, net. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in investment income, net.
The Company’s investment policy limits investments to certain types of instruments issued by institutions with investment grade credit ratings and places restrictions on maturities and concentration by type and issuer. Investments in which the Company has the ability and intent, if necessary, to liquidate, in order to supportCOVID-19 will negatively impact its current operations (including those with a contractual term greater than one year from the date of purchase), are classified as current.
The Company periodically evaluates its available-for-sale debt securities in unrealized loss positions to determine whether any impairment is a result of a credit lossfinancial results or other factors. This evaluation includes, but is not limited to, significant quantitative and qualitative assessments and estimates regarding credit ratings, significance of a security’s loss position, adverse conditions specifically related to the security, and the payment structure of the security.

AllowanceSignificant Accounting Policies
During the first quarter of 2021, there were no changes to the Company’s significant accounting policies as described in the Company’s Annual Report on Form 10-K for Doubtful Accountsthe year ended December 31, 2020, except as described in the Recently Adopted Accounting Pronouncements section below.
Reclassifications
Certain prior year amounts have been reclassified to conform to the current year presentation in the condensed consolidated financial statements and accompanying notes to the condensed consolidated financial statements.
Recent Accounting Pronouncements
Recently Adopted Accounting Pronouncements
In August 2020, The Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2020-06, Debt – Debt with Conversion and Other Options (subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). This update simplifies the accounting for convertible debt instruments by removing the beneficial conversion and cash conversion separation models for convertible instruments. Under the update, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives or that do not result in substantial premiums accounted for as paid-in capital. The update also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share and the treasury stock method will no longer be available. This standard may be adopted through either a modified retrospective method of transition or a full retrospective method of transition. The amendments in this update are effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020.
The Company estimates an allowance for doubtful accounts against accounts receivable using historical collection trends, agingadopted the standard on January 1, 2021 through application of accounts, current and future implications surrounding the abilityfull retrospective method of transition. This method of adoption was applied to collect suchenhance comparability between the periods presented in the Company’s financial statements. The Company applied the standard to convertible notes outstanding as economic conditions, and regulatory changes. of the date of the first offering of the Company’s outstanding convertible notes as discussed in Note 9.
The allowance for doubtful accounts is evaluated on a regular basis and adjusted when trends, significant events or other substantive evidence indicate that expected collectionsCompany’s convertible debt instruments will be less than applicable accrual rates. At Marchaccounted for as a single liability measured at its amortized cost. The notes are no longer bifurcated between debt and equity, rather accounted for entirely as debt at face value net of any discount or premium and issuance costs. Interest expense is comprised of (1) cash interest payments, (2) amortization of any debt discounts or premiums based on the original offering, and (3) amortization of any debt issuance costs. Gain or loss on extinguishment of convertible notes is calculated as the difference between the (i) fair value of the consideration transferred and (ii) the sum of the carrying value of the debt at the time of repurchase.
As of January 1, 2019, the cumulative effect of adoption resulted in a decrease in additional-paid-in-capital of $260.2 million, a decrease in accumulated deficit of $26.6 million, and an increase to net deferred tax assets of $55.7 million offset by a corresponding increase of $55.7 million in the valuation allowance. As of January 1, 2020, the cumulative effect of adoption resulted in a decrease in additional-paid-in-capital of $227.8 million, an increase in accumulated deficit of $102.6 million, and an increase to the net deferred tax assets of $83.2 million offset by a corresponding increase of $74.7 million in the valuation allowance resulting in a net decrease of $8.5 million in recorded deferred tax liabilities.

InventoryNet Loss Per Share
Basic net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average common shares outstanding during the period. Basic and diluted net loss per share is stated at the lower of cost or net realizable value. The Company determines the cost of inventory using the first-in, first out method (“FIFO”). The Company estimates the recoverability of inventory by reference to internal estimates of future demands and product life cycles, including expiration. The Company periodically analyzes its inventory levels to identify inventory that may expire prior to expected sale, no longer meet quality specifications, or has a cost basis in excess of its estimated realizable value and records a charge to cost of sales for such inventory as appropriate.
Direct and indirect manufacturing costs incurred during process validation with probable future economic benefit are capitalized.

The discounted cash flow model requires assumptions aboutCompany applied the timing and amountstandard to convertible notes outstanding as of future net cash flows, risk, the costdate of capital, terminal values and market participants.
Patent costs are capitalizedthe first offering of the Company’s outstanding convertible notes as incurred, only if the Company determines that there is some probable future economic benefit derived from the transaction. A capitalized patent is amortized over its estimated useful life, beginning when such patent is approved. Capitalized patent costs are expensed upon disapproval, upon a decision by the Company to no longer pursue the patent or when the related intellectual property is either sold or deemed to be no longer of value to the Company. Other than the transactions discussed in Note 5 below,9.
The Company’s convertible debt instruments will be accounted for as a single liability measured at its amortized cost. The notes are no longer bifurcated between debt and equity, rather accounted for entirely as debt at face value net of any discount or premium and issuance costs. Interest expense is comprised of (1) cash interest payments, (2) amortization of any debt discounts or premiums based on the Company determined that all patent costs incurred duringoriginal offering, and (3) amortization of any debt issuance costs. Gain or loss on extinguishment of convertible notes is calculated as the difference between the (i) fair value of the consideration transferred and (ii) the sum of the carrying value of the debt at the time of repurchase.
As of January 1, 2019, the cumulative effect of adoption resulted in a decrease in additional-paid-in-capital of $260.2 million, a decrease in accumulated deficit of $26.6 million, and an increase to net deferred tax assets of $55.7 million offset by a corresponding increase of $55.7 million in the valuation allowance. As of January 1, 2020, the cumulative effect of adoption resulted in a decrease in additional-paid-in-capital of $227.8 million, an increase in accumulated deficit of $102.6 million, and an increase to the net deferred tax assets of $83.2 million offset by a corresponding increase of $74.7 million in the valuation allowance resulting in a net decrease of $8.5 million in recorded deferred tax liabilities. As of December 31, 2020, the cumulative effect of adoption resulted in an increase in the net carrying amount of convertible notes, net, current portion of $57.3 million and convertible notes, net, less current portion of $540.9 million, a decrease in additional-paid-in-capital of $510.3 million and other long-term liabilities of $10.2 million, an increase in accumulated deficit of $77.7 million, and an increase to net deferred tax assets of $146.0 million offset by a corresponding increase of $135.8 million in the valuation allowance resulting in a net decrease of $10.2 million in recorded deferred tax liabilities.

Acquired In-process Research and Development (IPR&D)
Acquired IPR&D represents the fair value assigned to research and development assets that have not reached technological feasibility. The value assigned to acquired IPR&D is determinedthree months ended March 31, 2020 increased by estimating the costs to develop the acquired technology into commercially viable products, estimating the resulting revenues from the projects and discounting the net cash flows to present value. The revenues and cost projections used to value acquired IPR&D are, as applicable, reduced based on the probability of success. IPR&D projects acquired in a business combination that are not complete are capitalized and accounted for as indefinite-lived intangible assets until completion or abandonment of the related R&D efforts. Upon successful completion of the project, the capitalized amount is$0.20 per share.

amortized over its estimated useful life. If a project is abandoned, all remaining capitalized amounts are written off immediately. There are often major risks and uncertainties associated with IPR&D projects as we are required to obtain regulatory approvals in order to be able to market the resulting products. Such approvals require completing clinical trials that demonstrate the products effectiveness. Consequently, the eventual realized value of the IPR&D project may vary from its fair value at the date of acquisition, and IPR&D impairment charges may occur in future periods.
Capitalized IPR&D projects are tested for impairment annually and whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company considers various factors for potential impairment, including the current legal and regulatory environment and the competitive landscape. Adverse clinical trial results, significant delays in obtaining marketing approval, the inability to bring a product to market and the introduction or advancement of competitors' products could result in partial or full impairment of the related intangible assets.
Goodwill​
The Company evaluates goodwill for possible impairment in accordance with Accounting Standards Codification (“ASC”) 350 on an annual basis during the fourth quarter, or more frequently if events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Qualitative factors considered in this assessment include industry and market conditions, overall financial performance, and other relevant events and factors affecting the Company's business. Based on the qualitative assessment, if it is determined that the fair value of goodwill is more likely than not to be less than its carrying amount, the fair value of a reporting unit will be calculated and compared with its carrying amount and an impairment charge will be recognized for the amount that the carrying value exceeds the fair value.
Impairment of Long-Lived Assets
The Company evaluates the fair value of long-lived assets, which include property, plant and equipment, intangible assets, and investments in privately held companies, for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. There were 0 impairment losses for the periods ended March 31, 2020 and December 31, 2019.
Fair Value Measurements
The Financial Accounting Standards Board (“FASB”) has issued authoritative guidance that requires fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under that standard, fair value measurements are separately disclosed by level within the fair value hierarchy. The fair value hierarchy establishes and prioritizes the inputs used to measure fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs. Observable inputs are inputs that reflect the assumptions that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.
Convertible Notes
The Company accounts for convertible debt instruments that may be settled in cash or equity upon conversion by separating the liability and equity components of the instruments in a manner that reflects the Company’s nonconvertible debt borrowing rate. The Company determines the carrying amount of the liability component of the convertible notes by using assumptions that market participants would use in pricing a debt instrument, including

market interest rates, credit standing, yield curves and volatilities. Determining the fair value of the debt component requires the use of accounting estimates and assumptions. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the debt component, and the associated non-cash interest expense.
Leases
The Company acts as lessee under all its lease agreements, which includes operating leases for corporate offices, laboratory space, warehouse space, vehicles and certain laboratory and office equipment. The Company also has finance leases for certain equipment, which are not material to the Company’s condensed consolidated financial statements.
The Company determines whether an arrangement is, or contains, a lease at inception. At the beginning of fiscal year 2019, the company adopted ASC Topic 842. The Company records the present value of operating lease payments as right-of-use (“ROU”) assets and lease liabilities on the condensed consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments based on the present value of lease payments over the lease term. Classification of operating lease liabilities as either current or non-current is based on the expected timing of payments due under the Company’s obligations.
As most of the Company’s leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate is the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term and at an amount equal to the lease payments in a similar economic environment. In order to determine the appropriate incremental borrowing rates, the Company has used a number of factors including the credit rating, and the lease term. Certain vehicle leases include variable lease payments that depend on an index or rate. Those lease payments are initially measured using the index or rate at the lease commencement date.
The ROU asset also consists of any lease incentives received. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. “Reasonably certain” is assessed internally based on economic, industry, company, strategic and contractual factors. The leases have remaining lease terms of 1 year to 15 years, some of which include options to extend the lease for up to 10 years, and some of which include options to terminate the lease within 1 year. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense.
The Company has taken advantage of certain practical expedients offered to registrants at adoption of ASC 842. The Company does not apply the recognition requirements of ASC 842 to short-term leases. Instead, those lease payments are recognized in profit or loss on a straight-line basis over the lease term. Further, as a practical expedient, all lease contracts are accounted for as one single lease component, as opposed to separating lease and non-lease components to allocate the consideration within a single lease contract.
Net Loss Per Share​Share
Basic net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average common shares outstanding during the period. Basic and diluted net loss per share is the same because all outstanding common stock equivalents have been excluded, as they are anti-dilutive as a result of the Company’s losses.

Revenue Recognition​
Revenues are recognized when control of the promised services are transferred to the patient, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. To determine revenue recognition for the arrangements that the Company determines are within the scope of FASB ASC Topic 606, Revenue from Contracts with Customers, the Company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 2 for further discussion.
Foreign Currency Translation
Prior to 2019, the Company’s international subsidiaries functional currency was the local currency and assets and liabilities were translated into U.S. dollars at the period-end exchange rate or historical rates, as appropriate. Condensed consolidated statements of operations were translated at average exchange rates for the period, and the cumulative translation adjustments resulting from changes in exchange rates were included intransaction prices was $1.7 million and $5.4 million for the Company’s condensed consolidated balance sheet as a component of additional paid-in capital. In 2019three months ended March 31, 2021 and 2020, the Company’s international subsidiaries use the U.S. dollar as the functional currency, resulting in the Company not being subject to gains and losses from foreign currency translation of the subsidiary financial statements. The Company recognizes gains and losses from foreign currency transactions in the condensed consolidated statements of operations. Net foreign currency transaction gains or losses were not material to the condensed consolidated statements of operations for the periods presented.
Reclassifications
Certain prior year amounts have been reclassified to conform to the current year presentation in the condensed consolidated financial statements and accompanying notes to the condensed consolidated financial statements including the amortization of acquired intangible assets, which is now presented as a separate line item on the Company's condensed consolidated statements of operations and was previously included in cost of sales, research and development, and general and administrative expenses.

Recent Accounting Pronouncements
Recently Adopted Accounting Pronouncements
In June 2016, the FASBAugust 2020, The Financial Accounting Standards Board issued ASUAccounting Standards Update (“ASU”) No. 2016-13,2020-06, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The updated guidance requires companies to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions,Debt – Debt with Conversion and reasonable supportable forecasts. This replaces the existing incurred loss modelOther Options (subtopic 470-20) and is applicable to the measurement of credit losses on financial assets, including trade receivables. The updates also require available-for-sale debt security credit losses to be recognized as allowances rather than a reduction in amortized cost.The guidance was adopted by the Company on January 1, 2020. The requirements of the ASU did not result in the recognition of a material allowance for current expected credit losses, as the Company’s analysis of collectability looks at historical experience as well as current and future implications surrounding the ability to collect. Adoption of the updated guidance did not have a material impact on the Company’s condensed consolidated financial statements.
In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments –Credit Losses, Topic 815, Derivatives and Hedging and Topic 825, Financial Instruments. The updated guidance provides clarity regarding measurement of securities without readily determinable fair values. The guidance was adopted on January 1, 2020 and did not have a material impact on the Company's condensed consolidated financial statements.
In August 2018, the FASB issued ASU 2018-15, Intangibles –Goodwill and Other –Internal-Use Software(Subtopic 350-40)– Contracts in Entity’s Own Equity (Subtopic 815-40). The updated provided guidance for evaluating the accounting for fees paid by a customer in a cloud computing arrangement that is a service contract. The guidance was adopted on a prospective basis, beginning on January 1, 2020 and it did not have a material impact on the Company's condensed consolidated financial statements.
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820); Disclosure Framework -Changes to the Disclosure Requirements for Fair Value Measurement. The guidance provided an update to the disclosure requirements for fair value measurements under the scope of ASC 820. The updates were adopted on January 1, 2020 and did not have a material impact on the Company’s condensed consolidated financial statements.
In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808). The update provided additional guidance regarding the interaction between Topic 808 on Collaborative Arrangements and Topic 606 on Revenue Recognition. The guidance was adopted on January 1, 2020 and did not have a material impact on the Company's condensed consolidated financial statements.
In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. TheThis update simplifies the accounting for income taxesconvertible debt instruments by removing the beneficial conversion and cash conversion separation models for convertible instruments. Under the update, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives or that do not result in substantial premiums accounted for as paid-in capital. The update also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share and the treasury stock method will no longer be available. This standard may be adopted through removing exceptions related to certain intraperiod allocations and deferred tax liabilities; clarifying guidance primarily related to evaluating the step-up tax basis for goodwilleither a modified retrospective method of transition or a full retrospective method of transition. The amendments in a business combination; and reflecting enacted changes in tax laws or rates in the annual effective tax rate. The amended guidance isthis update are effective for fiscal years beginning after December 15, 2021, including interim and annual periods in 2021, however earlywithin those fiscal years. Early adoption is permitted. permitted, but no earlier than fiscal years beginning after December 15, 2020.
The Company adopted the guidance early,standard on January 1, 2021 through application of the full retrospective method of transition. This method of adoption was applied to enhance comparability between the periods presented in the Company’s financial statements. The Company applied the standard to convertible notes outstanding as of the date of the first offering of the Company’s outstanding convertible notes as discussed in Note 9.
The Company’s convertible debt instruments will be accounted for as a single liability measured at its amortized cost. The notes are no longer bifurcated between debt and equity, rather accounted for entirely as debt at face value net of any discount or premium and issuance costs. Interest expense is comprised of (1) cash interest payments, (2) amortization of any debt discounts or premiums based on the original offering, and (3) amortization of any debt issuance costs.

Net Loss Per Share
Basic net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average common shares outstanding during the period. Basic and diluted net loss per share is the same because all outstanding common stock equivalents have been excluded, as they are anti-dilutive as a result of the Company’s losses.
The following potentially issuable common shares were not included in the computation of diluted net loss per share because they would have an anti-dilutive effect due to net losses for each period:

(2) REVENUE
The Company’s revenue is primarily generated by its laboratory testing services utilizing its Cologuard, and Oncotype DX, and COVID-19 tests. The services are completed upon release of a patient’s test result to the ordering healthcare provider.
The core principle of ASC 606 is that the Company recognizes revenue to depict the transfer of 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. The Company recognizes revenues from its products in accordance with that core principle, and key aspects considered by the Company include the following:
Contracts​
The Company’s customer is the patient, but the Company does not enter into a formal reimbursement contract with a patient. Accordingly, the Company establishes a contract with a patient in accordance with other customary business practices.
Approval of a contract is established via the order submitted by the patient’s healthcare provider and the receipt of a sample in the laboratory.
The Company is obligated to perform its laboratory services upon acceptance of a sample, and the patient and/or applicable payer are obligated to reimburse the Company for services rendered based on the patient’s insurance benefits.
Payment terms are a function of a patient’s existing insurance benefits, including the impact of coverage decisions with CMS and applicable reimbursement contracts established between the Company and payers. However, when an order is received for a patient with no active insurance, the Company requires payment from the patient prior to the commencement of the Company’s performance obligations.
Once the Company releases a patient’s test result to the ordering healthcare provider, the Company is legally able to collect payment and bill an insurer, patient and/or health system, depending on payer contract status or patient insurance benefit status.
The Company’s consideration is deemed to be variable, and the Company considers collection of such consideration to be probable to the extent that it is unconstrained.
Performance obligations
A performance obligation is a promise in a contract to transfer a distinct good or service (or a bundle of goods or services) to the customer. The Company’s contracts have a single performance obligation, which is satisfied upon rendering of services, which culminates in the release of a patient’s test result to the ordering healthcare provider. The Company elects the practical expedient related to disclosure of unsatisfied performance obligations, as the duration of time between sample receipt and the release of a valid test result to the ordering healthcare provider is far less than one year.
Transaction price
The transaction price is the amount of consideration that the Company expects to collect in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties (for example, some sales taxes). The consideration expected from a contract with a customer may include fixed amounts, variable amounts, or both.
The consideration derived from the Company’s contracts is deemed to be variable due to several factors such as the amount of contractual adjustments, any patient co-payments, deductibles or patient adherence incentives, the existence of secondary payers, and claim denials.

(Unaudited)
The Company estimates the amount of variable consideration using the expected value method, which represents the sum of probability-weighted amounts in a range of possible consideration amounts. When estimating the amount of variable consideration, the Company considers several factors, such as historical collections experience, patient insurance eligibility and payer reimbursement contracts.
The Company limits the amount of variable consideration included in the transaction price to the unconstrained portion of such consideration. In other words, the Company recognizes revenue up to the amount of variable consideration that is not subject to a significant reversal until additional information is obtained or the uncertainty associated with the additional payments or refunds is subsequently resolved. Differences between original estimates and subsequent revisions, including final settlements, represent changes in the estimate of variable consideration and are included in the period in which such revisions are made. Revenue recognized from changes in transaction prices was $5.4 million and $1.5 million for the three months ended March 31, 2020 and 2019, respectively.
The Company monitors its estimates of transaction price to depict conditions that exist at each reporting date. If the Company subsequently determines that it will collect more or less consideration than it originally estimated for a contract with a patient, it will account for the change as an increase or decrease in the estimate of the transaction price (i.e., an upward or downward revenue adjustment) in the period identified.
When the Company does not have significant historical experience or that experience has limited predictive value, the constraint over estimates of variable consideration may result in no revenue being recognized upon release of the performance obligations associated with the Company’s tests, with recognition, generally occurring at the date of cash receipt.
Allocate transaction price
The transaction price is allocated entirely to the performance obligation contained within the contract with a patient.
Point in time recognition
The Company’s single performance obligation is satisfied at a point in time, and that point in time is defined as the date a patient’s successful test result is released to the patient’s ordering healthcare provider. The Company considers this date to be the time at which the patient obtains control of the promised test service.

Contract Balances
The timing of revenue recognition, billings and cash collections resultsbalances are reported in billed accounts receivable and deferred revenue on the condensed consolidated balance sheets. Generally, billing occurs subsequent to the release of a patient’s test result to the ordering healthcare provider, resulting in an account receivable. However, the Company sometimes receives advance payment from a patient before a test result is completed, resulting in deferred revenue. The deferred revenue balance is relieved upon release of the applicable patient’s test result to the ordering healthcare provider. As of March 31, 2020 and December 31, 2019, the deferred revenue balance is not material to the Company’s condensed consolidated financial statements.
Practical Expedients
The Company does not adjust the transaction price for the effects of a significant financing component, as at contract inception, the Company expects the collection cycle to be one year or less.
The Company expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within sales and marketing expensesother current liabilities in the Company’s condensed consolidated statementsbalance sheets and were $39.8 million and $25.0 million as of operations.March 31, 2021 and December 31, 2020, respectively. As of March 31, 2021, $38.5 million of the Company’s deferred revenue balance is a result of the billing terms pursuant to the existing COVID-19 laboratory service agreements (“LSAs”) with customers.
The Company incurs certain other costs that are incurred regardlessRevenue recognized for the three months ended March 31, 2021 and 2020, which was included in the deferred revenue balance at the beginning of whether a contract is obtained.

Goodwill
In March 2020, the Company recognized goodwill of $29.7 million from the acquisition of Paradigm Diagnostics, Inc. (“Paradigm”) and Viomics, Inc. (“Viomics”). Refer to the Company’s 2019 10-K for further discussion on goodwill recorded.
The Company evaluates goodwill for possible impairment in accordance with ASC 350 on an annual basis during the fourth quarter, or more frequently if events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Qualitative factors considered in this assessment include industry and market conditions, overall financial performance, and other relevant events and factors affecting the Company's business. Based on the qualitative assessment, if it is determined that the fair value of goodwill is more likely than not to be less than its carrying amount, the fair value of a reporting unit will be calculated and compared with its carrying amount and an impairment charge will be recognized for the amount that the carrying value exceeds the fair value. Due to the impact of COVID-19 on the Company’s operations, the Company performed a qualitative assessment of goodwill to determine if an event indicating impairment was present. No such indicators were identified as of March 31, 2020. There were 0 impairment losses for the periods ended March 31, 2020 and December 31, 2019. During the three months ended March 31, 2021 and 2020.

The three levels of the fair value hierarchy established are as follows:
Level 1    Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2    Pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
Level 3    Unobservable inputs that reflect the Company’s assumptions about the assumptions that market participants would use in pricing the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available.
The following table presents the Company’s fair value measurements as of March 31, 2021 along with the level within the fair value hierarchy in which the fair value measurements, in their entirety, fall.

Construction Loan Agreement
During December 2017, the Company entered into a loan agreement with Fifth Third Bank (formerly MB Financial Bank, N.A.) (the “Construction Loan Agreement”), which provides the Company with a non-revolving construction loan (the “Construction Loan”) of $25.6 million. The Company is using the Construction Loan proceeds to finance the construction of an additional clinical laboratory and related facilities in Madison, Wisconsin. The Construction Loan is collateralized by the additional clinical laboratory and related facilities.
Pursuant to the Construction Loan Agreement, funds drawn will bear interest at a rate equal to the sum of the 1-month LIBOR rate plus 2.25 percent. Regular monthly payments are interest-only for the first 24 months, with further payments based on a 20-year amortization schedule. Amounts borrowed pursuant to the Construction Loan Agreement may be prepaid at any time without penalty. The maturity date of the Construction Loan Agreement is December 10, 2022.
In November 2017, Fifth Third Bank, on behalf of the Company, issued an Irrevocable Standby Letter of Credit in the amount of $0.6 million in favor of the City of Madison, Wisconsin (the “City Letter of Credit”). The City Letter of Credit is deemed to have been issued pursuant to the Construction Loan Agreement. The amount of the City Letter of Credit will reduce, dollar for dollar, the amount available for borrowing under the Construction Loan Agreement.
As a condition to Fifth Third Bank’s initial advance of loan proceeds under the Construction Loan Agreement, the Company was required to first invest at least $16.4 million of its own cash into the construction project. The Company fulfilled its required initial investment and made its first draw on the Construction Loan in Epic Sciences.June 2018. In December 2019, the Company began making monthly payments towards the outstanding principal balance plus accrued interest. As of March 31, 2021 and December 31, 2020, the outstanding balance was $23.4 million and $23.8 million, respectively, from the Construction Loan, including $0.7 million of interest incurred, which is accrued for as an interest reserve and represents a portion of the loan balance. The Company capitalized the $0.7 million of interest to the construction project. The Company incurred approximately $0.2 million of debt issuance costs related to the Construction Loan, which are recorded as a direct deduction from the liability. The debt issuance costs are being amortized over the life of the Construction Loan.
Fair ValueThe carrying amount of Long-Term Debtthe Construction Loan approximates fair value due to the short maturity of this instrument. The Construction Loan is privately held with no public market for this debt and Convertible Notes​therefore is classified as a Level 3 fair value measurement. The change in the fair value during the three months ended March 31, 2021 was due to payments made on the loan resulting in a decrease in the liability.
The Construction Loan Agreement was amended effective June 30, 2020 to include a financial covenant to maintain a minimum liquidity of $250 million and remove the minimum tangible net worth covenant. As of March 31, 2021, the Company is in compliance with the covenant included in the amended agreement.

In the event that the job creation goals are not met, the Company would be required to pay a penalty.
The Company records the earned financial incentives as the full-time equivalent positions are filled. The amount earned is recorded as a liability and amortized as a reduction of operating expenses over a two-year period, which is the timeframe when the TIFs will be repaid through property taxes.
As of December 31, 2019, the Company had earned and received payment of the full $4.6 million from the City of Madison. As of March 31, 2021 and December 31, 2020, the corresponding liability, which reflected when the expected benefit of the tax credit amortization would reduce future operating expenses, has been fully amortized.

Summary of Conversion Features
Until the six-months immediately preceding the maturity date of the applicable series of Notes, each series of Notes is convertible only upon the occurrence of certain events and during certain periods, as set forth in the Indentures filed at the time of the original offerings. On or after the date that is six-months immediately preceding the maturity date of the applicable series of Notes until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert such Notes at any time. The Notes will be convertible into cash, shares of the Company’s common stock (plus, if applicable, cash in lieu of any fractional share), or a combination of cash and shares of the Company’s common stock, at the Company’s election.
It is the Company’s intent and policy to settle all conversions through combination settlement. The initial conversion rate is 13.26, 8.96, and 8.21 shares of common stock per $1,000 principal amount for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively, which is equivalent to an initial conversion price of approximately $75.43, $111.66, and $121.84 per share of the Company’s common stock for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively. The 2025 Notes, 2027 Notes, and 2028 Notes may be convertible in up to 4.2 million, 6.7 million, and 9.4 million shares, respectively. The conversion rate is subject to adjustment upon the occurrence of certain specified events as set forth in the Indentures filed at the time of the original offerings but will not be adjusted for accrued and unpaid interest. In addition, holders of the Notes who convert their Notes in connection with a “make-whole fundamental change” (as defined in the Indenture), will, under certain circumstances, be entitled to an increase in the conversion rate.
If the Company undergoes a “fundamental change” (as defined in the Indenture), holders of the Notes may require the Company to repurchase for cash all or part of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest.
Based on the closing price of the Company’s common stock of $131.78 on March 31, 2021, the if-converted values exceed the principal amount by $235.3 million, $134.7 million, and $93.8 million for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively.
Ranking of Convertible Notes
The Notes are the Company’s senior unsecured obligations and (i) rank senior in right of payment to all of its future indebtedness that is expressly subordinated in right of payment to the Notes; (ii) rank equal in right of payment to each outstanding series thereof and to all of the Company’s future liabilities that are not so subordinated, unsecured indebtedness; (iii) are effectively junior to all of the Company’s existing and future secured indebtedness and other secured obligations, to the extent of the value of the assets securing that indebtedness and other secured obligations; and (iv) are structurally subordinated to all indebtedness and other liabilities of the Company’s subsidiaries.

Stock-Based Compensation ExpenseConstruction Loan Agreement
During December 2017, the Company entered into a loan agreement with Fifth Third Bank (formerly MB Financial Bank, N.A.) (the “Construction Loan Agreement”), which provides the Company with a non-revolving construction loan (the “Construction Loan”) of $25.6 million. The Company is using the Construction Loan proceeds to finance the construction of an additional clinical laboratory and related facilities in Madison, Wisconsin. The Construction Loan is collateralized by the additional clinical laboratory and related facilities.
Pursuant to the Construction Loan Agreement, funds drawn will bear interest at a rate equal to the sum of the 1-month LIBOR rate plus 2.25 percent. Regular monthly payments are interest-only for the first 24 months, with further payments based on a 20-year amortization schedule. Amounts borrowed pursuant to the Construction Loan Agreement may be prepaid at any time without penalty. The maturity date of the Construction Loan Agreement is December 10, 2022.
In November 2017, Fifth Third Bank, on behalf of the Company, issued an Irrevocable Standby Letter of Credit in the amount of $0.6 million in favor of the City of Madison, Wisconsin (the “City Letter of Credit”). The City Letter of Credit is deemed to have been issued pursuant to the Construction Loan Agreement. The amount of the City Letter of Credit will reduce, dollar for dollar, the amount available for borrowing under the Construction Loan Agreement.
As a condition to Fifth Third Bank’s initial advance of loan proceeds under the Construction Loan Agreement, the Company was required to first invest at least $16.4 million of its own cash into the construction project. The Company fulfilled its required initial investment and made its first draw on the Construction Loan in June 2018. In December 2019, the Company began making monthly payments towards the outstanding principal balance plus accrued interest. As of March 31, 2021 and December 31, 2020, the outstanding balance was $23.4 million and $23.8 million, respectively, from the Construction Loan, including $0.7 million of interest incurred, which is accrued for as an interest reserve and represents a portion of the loan balance. The Company capitalized the $0.7 million of interest to the construction project. The Company incurred approximately $0.2 million of debt issuance costs related to the Construction Loan, which are recorded as a direct deduction from the liability. The debt issuance costs are being amortized over the life of the Construction Loan.
The Company recorded approximately $29.6 millioncarrying amount of the Construction Loan approximates fair value due to the short maturity of this instrument. The Construction Loan is privately held with no public market for this debt and $16.2 milliontherefore is classified as a Level 3 fair value measurement. The change in stock-based compensation expensethe fair value during the three months ended March 31, 2021 was due to payments made on the loan resulting in a decrease in the liability.

Tax Increment Financing Loan Agreements
The Company entered into 2 separate Tax Increment Financing Loan Agreements (“TIFs”) in February 2019 and June 2019 with the City of Madison, Wisconsin. The TIFs provide for $4.6 million of financing in the aggregate. In return for the loans, the Company is obligated to create and maintain 500 full-time jobs over a five-year period, starting on the date of occupancy of the buildings constructed. In the event that the job creation goals are not met, the Company would be required to pay a penalty.
The Company records the earned financial incentives as the full-time equivalent positions are filled. The amount earned is recorded as a liability and amortized as a reduction of operating expenses over a two-year period, which is the timeframe when the TIFs will be repaid through property taxes.
As of December 31, 2019, the Company had earned and received payment of the full $4.6 million from the City of Madison. As of March 31, 2021 and December 31, 2020, the corresponding liability, which reflected when the expected benefit of the tax credit amortization would reduce future operating expenses, has been fully amortized.

The Company utilized a portion of the proceeds from the issuance of the 2027 Notes to settle a portion of the 2025 Notes in privately negotiated transactions. In March 2019, the Company used cash of $494.1 million and an aggregate of 2.2 million shares of the Company’s common stock valued at $182.4 million for total consideration of $676.5 million to settle $493.4 million of the 2025 Notes, of which $0.7 million was used to pay off interest accrued on the 2025 Notes. The transaction resulted in a loss on settlement of convertible notes of $187.7 million, which is reflected in accumulated deficit in the Company’s condensed consolidated balance sheets. The loss represents the difference between (i) the fair value of the consideration transferred and (ii) the carrying value of the debt at the time of repurchase.

Summary of Conversion Features
Until the six-months immediately preceding the maturity date of the applicable series of Notes, each series of Notes is convertible only upon the occurrence of certain events and during certain periods, as set forth in the Indentures filed at the time of the original offerings. On or after the date that is six-months immediately preceding the maturity date of the applicable series of Notes until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert such Notes at any time. The Notes will be convertible into cash, shares of the Company’s common stock (plus, if applicable, cash in lieu of any fractional share), or a combination of cash and shares of the Company’s common stock, at the Company’s election.
It is the Company’s intent and policy to settle all conversions through combination settlement. The initial conversion rate is 13.26, 8.96, and 8.21 shares of common stock per $1,000 principal amount for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively, which is equivalent to an initial conversion price of approximately $75.43, $111.66, and $121.84 per share of the Company’s common stock for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively. The 2025 Notes, 2027 Notes, and 2028 Notes may be convertible in up to 4.2 million, 6.7 million, and 9.4 million shares, respectively. The conversion rate is subject to adjustment upon the occurrence of certain specified events as set forth in the Indentures filed at the time of the original offerings but will not be adjusted for accrued and unpaid interest. In addition, holders of the Notes who convert their Notes in connection with a “make-whole fundamental change” (as defined in the Indenture), will, under certain circumstances, be entitled to an increase in the conversion rate.
If the Company undergoes a “fundamental change” (as defined in the Indenture), holders of the Notes may require the Company to repurchase for cash all or part of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest.
Based on the closing price of the Company’s common stock of $131.78 on March 31, 2021, the if-converted values exceed the principal amount by $235.3 million, $134.7 million, and $93.8 million for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively.
Ranking of Convertible Notes
The Notes are the Company’s senior unsecured obligations and (i) rank senior in right of payment to all of its future indebtedness that is expressly subordinated in right of payment to the Notes; (ii) rank equal in right of payment to each outstanding series thereof and to all of the Company’s future liabilities that are not so subordinated, unsecured indebtedness; (iii) are effectively junior to all of the Company’s existing and future secured indebtedness and other secured obligations, to the extent of the value of the assets securing that indebtedness and other secured obligations; and (iv) are structurally subordinated to all indebtedness and other liabilities of the Company’s subsidiaries.

Determining Fair Value
Valuation and Recognition – The fair value of each service-based option award is estimated on the date of grant using the Black-Scholes option-pricing model. The fair value of service-based awards for each restricted stock unit award is determined on the date of grant using the closing stock price on that day. The estimated fair value of these awards is recognized to expense using the straight-line method over the vesting period. For awards that vest when a performance condition is achieved, the Company performs an evaluation of internal and external factors to determine the number of shares that are most likely to vest based on the probability of what performance conditions will be met. The Black-Scholes pricing model utilizes the following assumptions:
Expected Term – Expected life of an option award is the average length of time over which the Company expects employees will exercise their options, which is based on historical experience with similar grants. Expected life of a market measure-based award is based on the applicable performance period.
Expected Volatility - Expected volatility is based on the Company’s historical stock volatility data over the expected term of the awards.
Risk-Free Interest Rate - The Company bases the risk-free interest rate on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent expected term.
Forfeitures - The Company recognizes forfeitures as they occur.
The fair value of each option is based on the assumptions in the following table:

The Investor and its majority owned community development entity are considered Variable Interest Entities (“VIEs”)2010 Employee Stock Purchase Plan, and the Company is2016 Inducement Award Plan (collectively, the primary beneficiary of the VIEs. This conclusion was reached based on the following:“Stock Plans”).
the ongoing activities of the VIEs — collecting and remitting interest and fees and NMTC compliance — were all considered in the initial design and are not expected to significantly affect performance throughout the life of the VIE;
contractual arrangements obligate the Company to comply with NMTC rules and regulations and provide various other guarantees to the Investor and community development entity;
the Investor lacks a material interest in the underlying economics of the project; and
the Company is obligated to absorb losses of the VIEs.
Because the Company is the primary beneficiary of the VIEs, they have been included in the consolidated financial statements. There are no other assets, liabilities or transactions in these VIEs outside of the financing transactions executed as part of the NMTC arrangement.

(12) DEBT
Construction Loan Agreement
During December 2017, the Company entered into a loan agreement with Fifth Third Bank (formerly MB Financial Bank, N.A.) (the “Construction Loan Agreement”), which provides the Company with a non-revolving construction loan (the “Construction Loan”) of $25.6 million. The Company is using the Construction Loan proceeds to finance the construction of an additional clinical laboratory and related facilities in Madison, Wisconsin. The Construction Loan is collateralized by the additional clinical laboratory and related facilities.
Pursuant to the Construction Loan Agreement, funds drawn will bear interest at a rate equal to the sum of the 1-month LIBOR rate plus 2.25 percent. Regular monthly payments are interest-only for the first 24 months, with further payments based on a 20-year amortization schedule. Amounts borrowed pursuant to the Construction Loan Agreement may be prepaid at any time without penalty. The maturity date of the Construction Loan Agreement is December 10, 2022.
In November 2017, Fifth Third Bank, on behalf of the Company, issued an Irrevocable Standby Letter of Credit in the amount of $0.6 million in favor of the City of Madison, Wisconsin (the “City Letter of Credit”). The City Letter of Credit is deemed to have been issued pursuant to the Construction Loan Agreement. The amount of the City Letter of Credit will reduce, dollar for dollar, the amount available for borrowing under the Construction Loan Agreement.
As a condition to Fifth Third’sThird Bank’s initial advance of loan proceeds under the Construction Loan Agreement, the Company was required to first invest at least $16.4 million of its own cash into the construction project. The Company fulfilled its required initial investment and made its first draw on the Construction Loan in June 2018. Starting inIn December 2019, the Company began making monthly payments towards the outstanding principal balance plus accrued interest. As of March 31, 20202021 and December 31, 2019,2020, the outstanding balance was $24.7$23.4 million and $25.0$23.8 million, respectively, from the Construction Loan, including $0.7 million of interest incurred, which is accrued for as an interest reserve and represents a portion of the loan balance. The Company capitalized the $0.7 million of interest to the construction project.

Issuances and Settlements
In January 2018, the Company issued and sold $690.0 million in aggregate principal amount of 1.0% Convertible Notes (the “January 2025 Notes”) with a maturity date of January 15, 2025. The January 2025 Notes accrue interest at a fixed rate of 1.0% per year, payable semi-annually in arrears on January 15 and July 15 of each year, beginning on July 15, 2018. The net proceeds from the issuance of the January 2025 Notes were approximately $671.1 million, after deducting underwriting discounts and commissions and the offering expenses payable by the Company.
In June 2018, the Company issued and sold an additional $218.5 million in aggregate principal amount of 1.0% Convertible Notes (the “June 2025 Notes”). The June 2025 Notes were issued under the same indenture pursuant to which the Company previously issued the January 2025 Notes (the “Indenture”). The January 2025 Notes and the June 2025 Notes (collectively, the “2025 Notes”) have identical terms (including the same January 15, 2025 maturity date) and are treated as a single series of securities. The net proceeds from the issuance of the June 2025 Notes were approximately $225.3 million, after deducting underwriting discounts and commissions and the offering expenses payable by the Company.

The Company utilized a portion of the proceeds from the issuance of the 2027 Notes to settle a portion of the 2025 Notes in privately negotiated transactions. In March 2019, the Company used cash of $494.1 million and an aggregate of 2.2 million shares of the Company’s common stock valued at $182.4 million for total consideration of $676.5 million to settle $493.4 million of the 2025 Notes, of which $0.7 million was used to pay off interest accrued on the 2025 Notes. The transaction resulted in a loss on settlement of convertible notes of $187.7 million, which is reflected in accumulated deficit in the Company’s condensed consolidated balance sheets. The loss represents the difference between (i) the fair value of the consideration transferred and (ii) the carrying value of the debt at the time of repurchase.
In February 2020, the Company issued and sold $1.15 billion in aggregate principal amount of 0.375% Convertible Notes (the “2028 Notes” and, collectively with the 2025 Notes and the 2027 Notes, the “Notes”) with a maturity date of March 1, 2028. The 2028 Notes accrue interest at a fixed rate of 0.375% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2020. The net proceeds from the issuance of the 2028 Notes were approximately $1.13 billion, after deducting underwriting discounts and commissions and the offering expenses payable by the Company.
In February 2020, the Company used $150.1 million of the proceeds from the issuance of the 2028 Notes to settle $100.0 million of the 2025 Notes, of which $0.1 million was used to pay off interest accrued on the 2025 Notes. The transaction resulted in a loss on settlement of convertible notes of $50.8 million, which is recorded in interest expense in the Company’s condensed consolidated statement of operations. The loss represents the difference between (i) the fair value of the consideration transferred and (ii) the carrying value of the debt at the time of repurchase.
Summary of Conversion Features
Until the six-months immediately preceding the maturity date of the applicable series of Notes, each series of Notes is convertible only upon the occurrence of certain events and during certain periods, as set forth in the Indentures filed at the time of the original offerings. On or after the date that is six-months immediately preceding the maturity date of the applicable series of Notes until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert such Notes at any time. The Notes will be convertible into cash, shares of the Company’s common stock (plus, if applicable, cash in lieu of any fractional share), or a combination of cash and shares of the Company’s common stock, at the Company’s election.
It is the Company’s intent and policy to settle all conversions through combination settlement. The initial conversion rate is 13.26, 8.96, and 8.21 shares of common stock per $1,000 principal amount for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively, which is equivalent to an initial conversion price of approximately $75.43, $111.66, and $121.84 per share of the Company’s common stock for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively. The 2025 Notes, 2027 Notes, and 2028 Notes may be convertible in up to 4.2 million, 6.7 million, and 9.4 million shares, respectively. The conversion rate is subject to adjustment upon the occurrence of certain specified events as set forth in the Indentures filed at the time of the original offerings but will not be adjusted for accrued and unpaid interest. In addition, holders of the Notes who convert their Notes in connection with a “make-whole fundamental change” (as defined in the Indenture), will, under certain circumstances, be entitled to an increase in the conversion rate.
If the Company undergoes a “fundamental change” (as defined in the Indenture), holders of the Notes may require the Company to repurchase for cash all or part of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest.
Based on the closing price of the Company’s common stock of $131.78 on March 31, 2021, the if-converted values exceed the principal amount by $235.3 million, $134.7 million, and $93.8 million for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively.
Ranking of Convertible Notes
The Notes are the Company’s senior unsecured obligations and (i) rank senior in right of payment to all of its future indebtedness that is expressly subordinated in right of payment to the Notes; (ii) rank equal in right of payment to each outstanding series thereof and to all of the Company’s future liabilities that are not so subordinated, unsecured indebtedness; (iii) are effectively junior to all of the Company’s existing and future secured indebtedness and other secured obligations, to the extent of the value of the assets securing that indebtedness and other secured obligations; and (iv) are structurally subordinated to all indebtedness and other liabilities of the Company’s subsidiaries.

Pursuant to the Company’s agreement with Mayo, the Company is required to pay Mayo a low-single-digit royalty on the Company’s net sales of current and future products using the licensed Mayo intellectual property each year during the term of the Mayo agreement.
As part of the most recent amendment, the Company agreed to pay Mayo an additional $6.3 million, payable in five equal annual installments through 2024. The annual installments are recorded in research and development expenses in the Company’s condensed consolidated statements of operations.
The license agreement will remain in effect, unless earlier terminated by the parties in accordance with the agreement, until the last of the licensed patents expires in 2038 (or later, if certain licensed patent applications are issued). However, if the Company is still using the licensed Mayo know-how or certain Mayo-provided biological specimens or their derivatives on such expiration date, the term shall continue until the earlier of the date the Company stops using such know-how and materials and the date that is five years after the last licensed patent expires. The license agreement contains customary termination provisions and permits Mayo to terminate the license agreement if the Company sues Mayo or its affiliates, other than any such suit claiming an uncured material breach by Mayo of the license agreement.
In addition to granting the Company a license to the covered Mayo intellectual property, Mayo provides the Company with product development and research and development assistance pursuant to the license agreement and other collaborative arrangements. In September 2020, Mayo also agreed to make available certain personnel to provide such assistance through January 2025. In connection with this collaboration, the Company incurred charges of $1.2 million and $1.0 million for the three months ended March 31, 2021 and 2020, respectively. The charges incurred in connection with this collaboration are recorded in research and development expenses in the Company’s condensed consolidated statements of operations.
John Hopkins University (“JHU”)
Through the acquisition of Thrive, the Company acquired a worldwide exclusive license agreement with JHU for use of several JHU patents and licensed know-how. The license is designed to enable the Company to leverage JHU proprietary data in the development and commercialization of a blood-based, multi-cancer screening test. The agreement terms include single-digit sales-based royalties and sales-based milestone payments of $10.0 million, $15.0 million, $20.0 million and upon achieving calendar year licensed product revenue using JHU proprietary data of $0.50 billion, $1.00 billion, and $1.50 billion, respectively.

(11) PFIZER PROMOTION AGREEMENT
In August 2018, the Company entered into a Promotion Agreement (the “Original Promotion Agreement”) with Pfizer Inc. (“Pfizer”), which was amended and restated in October 2020 (the “Restated Promotion Agreement”). The Restated Promotion Agreement extends the relationship between the Company and Pfizer and restructures the manner in which the Company compensates Pfizer for promotion of the Cologuard test through a service fee, and provision of certain other sales and marketing services related to the Cologuard test. The Restated Promotion Agreement includes fixed and performance-related fees, some of which retroactively went into effect on April 1, 2020. All payments to Pfizer are recorded in sales and marketing expenses in the Company’s condensed consolidated statements of operations.
Under the Original Promotion Agreement, the service fee was calculated based on incremental gross profits over specified baselines during the term. Under the Restated Promotion Agreement, the service fee provides a fee-for-service model that includes certain fixed fees and performance-related bonuses. The performance-related bonuses are contingent upon the achievement of certain annual performance criteria with any applicable expense being recognized ratably upon achievement of the payment becoming probable. The Company incurred charges of $22.7 million and $19.4 million for the service fee for the three months ended March 31, 2021 and 2020, respectively. The Company incurred charges of $26.6 million and $19.5 million for promotion, sales and marketing services performed by Pfizer on behalf of the Company during the three months ended March 31, 2021 and 2020, respectively. During 2022, and contingent upon the achievement of certain Cologuard test revenue metrics during 2021, the Company will pay Pfizer a royalty based on a low single-digit royalty rate applied to actual 2022 Cologuard test revenues. The term of the Restated Promotion Agreement runs through December 31, 2022.

(14)(15) NEW MARKET TAX CREDIT
During the fourth quarter of 2014, the Company received approximately $2.4 million in net proceeds from financing agreements related to working capital and capital improvements at 1 of its Madison, Wisconsin facilities. This financing arrangement was structured with an unrelated third-party financial institution (the “Investor”), an investment fund, and its majority owned community development entity in connection with the Company’s participation in transactions qualified under the federal New Markets Tax Credit (“NMTC”) program, pursuant to Section 45D of the Internal Revenue Code of 1986, as amended. The Company is required to be in compliance through December 2021 with various regulations and contractual provisions that apply to the NMTC arrangement. Noncompliance with applicable requirements could result in the Investor’s projected tax benefits not being realized and, therefore, require the Company to indemnify the Investor for any loss or recapture of NMTC related to the financing until such time as the recapture provisions have expired under the applicable statute of limitations. The Company does not anticipate any credit recapture will be required in connection with this financing arrangement.
The Investor and its majority owned community development entity are considered Variable Interest Entities (“VIEs”) and the Company is the primary beneficiary of the VIEs. This conclusion was reached based on the following:
the ongoing activities of the VIEs — collecting and remitting interest and fees and NMTC compliance — were all considered in the initial design and are not expected to significantly affect performance throughout the life of the VIE;
contractual arrangements obligate the Company to comply with NMTC rules and regulations and provide various other guarantees to the Investor and community development entity;
the Investor lacks a material interest in the underlying economics of the project; and
the Company is obligated to absorb losses of the VIEs.

Because the Company is the primary beneficiary of the VIEs, they have been included in the consolidated financial statements. There are no other assets, liabilities or transactions in these VIEs outside of the financing transactions executed as part of the NMTC arrangement.

(16) WISCONSIN ECONOMIC DEVELOPMENT TAX CREDITS
During the first quarter of 2015, the Company entered into an agreement with the Wisconsin Economic Development Corporation (“WEDC”) to earn $9.0 million in refundable tax credits ifon the condition that the Company expends $26.3 million in capital investments and establishes and maintains 758 full-time positions over a seven-yearseven-year period. The tax credits earned are first applied against the tax liability otherwise due, and if there is no such liability present, the claim for tax credits will be reimbursed in cash to the Company. The maximum amount of the refundable tax credit to be earned for each year is fixed, and the Company earns the credits by meeting certain capital investment and job creation thresholds over the seven-yearseven-year period. Should the Company earn and receive the job creation tax credits but not maintain those full-time positions through the end of the agreement, the Company may be required to pay those credits back to the WEDC.
The Company records the earned tax credits as job creation and capital investments occur. The amount of tax credits earned is recorded as a liability and amortized as a reduction of operating expenses over the expected period of benefit. The tax credits earned from capital investment are recognized as an offset to depreciation expense over the expected life of the acquired capital assets. The tax credits earned related to job creation are recognized as an offset to operational expenses over the life of the agreement, as the Company is required to maintain the minimum level of full-time positions through the seven-yearseven-year period.
As of March 31, 2020,2021, the Company has earned all $9.0 million of the refundable tax credits and has received payment of $5.9$7.5 million from the WEDC. The unpaid portion is $3.1$1.5 million, of which $1.6 million is reported in prepaid expenses and other current assets and $1.5 million is reported in other long-term assets, reflecting when collection of the refundable tax credits is expected to occur. As of March 31, 2021 and December 31, 2020, the Company also has recorded a $1.6 millioncorresponding liability, in other current liabilities, which reflectsreflected when the expected benefit of the tax credit amortization willwould reduce future operating expenses.​expenses, has been fully amortized.
During the three months ended March 31, 2020, and 2019, the Company amortized $0.6 million and $0.6 million, respectively, of the tax credits earned as a reduction of operating expenses.

(1)As each of the convertible instruments may be settled in cash upon conversion, for accounting purposes, they were separated into a liability component and an equity component. The amount allocated to the equity component is the difference between the principal value of the instrument and the fair value of the liability component at issuance. The resulting debt discount is being amortized to interest expense at the respective effective interest rate over the contractual term of the debt. A portion of the 2025 Convertible Notes have been extinguished or converted. The fair value of the liability component at issuance reflected above represents the liability value at issuance for the applicable portion of the 2025 Notes which remain outstanding at March 31 2020 and December 31, 2019. The fair value of the liability component of the 2025 Notes at issuance was $654.8 million with the equity component being $269.7 million.

Issuances and Settlements​
In January 2018, the Company issued and sold $690.0 million in aggregate principal amount of 1.0% Convertible Notes (the “January 2025 Notes”) with a maturity date of January 15, 2025. The January 2025 Notes accrue interest at a fixed rate of 1.0% per year, payable semi-annually in arrears on January 15 and July 15 of each year, beginning on July 15, 2018. The net proceeds from the issuance of the January 2025 Notes were approximately $671.1 million, after deducting underwriting discounts and commissions and the offering expenses payable by the Company.​
In June 2018, the Company issued and sold an additional $218.5 million in aggregate principal amount of 1.0% Convertible Notes (the “June 2025 Notes”). The June 2025 Notes were issued under the same indenture pursuant to which the Company previously issued the January 2025 Notes (the “Indenture”). The January 2025 Notes and the June 2025 Notes (collectively, the “2025 Notes”) have identical terms and will be treated as a single series of securities. The net proceeds from the issuance of the June 2025 Notes were approximately $225.3 million, after deducting underwriting discounts and commissions and the offering expenses payable by the Company.​
In March 2019, the Company issued and sold $747.5 million in aggregate principal amount of 0.375% Convertible Notes (the “2027 Notes”) with a maturity date of March 15, 2027. The 2027 Notes accrue interest at a fixed rate of 0.375% per year, payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2019. The net proceeds from the issuance of the 2027 Notes were approximately $729.5 million, after deducting underwriting discounts and commissions and the offering expenses payable by the Company.​
The Company utilized a portion of the proceeds from the issuance of the 2027 Notes to settle a portion of the 2025 Notes in privately negotiated transactions. In March 2019, the Company used cash of $494.1 million and an aggregate of 2.2 million shares of the Company’s common stock valued at $182.4 million for total consideration of $676.5 million to settle $493.4 million of the 2025 Notes, of which $375.0 million was allocated to the liability component, $300.8 million was allocated to the equity component, and $0.7 million was used to pay off interest accrued on the 2025 Notes. The consideration transferred was allocated to the liability and equity components of the 2025 Notes using the equivalent rate that reflected the borrowing rate for a similar non-convertible debt instrument immediately prior to settlement. The transaction resulted in a loss on settlement of convertible notes of $10.6 million, which is recorded in interest expense in the Company’s condensed consolidated statement of operations. The loss represents the difference between (i) the fair value of the liability component and (ii) the sum of the carrying value of the debt component and any unamortized debt issuance costs at the time of repurchase.
In February 2020, the Company issued and sold $1,150.0 million in aggregate principal amount of 0.375% Convertible Notes (the “2028 Notes” and, collectively with the 2025 Notes and the 2027 Notes, the “Notes”) with a maturity date of March 1, 2028. The 2028 Notes accrue interest at a fixed rate of 0.375% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2020. The net proceeds from the issuance of the 2028 Notes were approximately $1,125.6 million, after deducting underwriting discounts and commissions and the offering expenses payable by the Company.​
In February 2020, the Company used $150.1 million of the proceeds from the issuance of the 2028 Notes to settle $100.0 million of the 2025 Notes, of which $85.5 million was allocated to the liability component, $64.2 million, net of a tax impact of $0.3 million, was allocated to the equity component, and $0.1 million was used to pay off interest accrued on the 2025 Notes. The consideration transferred was allocated to the liability and equity components of the 2025 Notes using the equivalent rate that reflected the borrowing rate for a similar non-convertible debt instrument immediately prior to settlement. The transaction resulted in a loss on settlement of convertible notes of $8.0 million, which is recorded in interest expense in the Company’s condensed consolidated statement of operations. The loss represents the difference between (i) the fair value of the liability component and (ii) the sum of the carrying value of the debt component and any unamortized debt issuance costs at the time of repurchase.​

Summary of Conversion Features​
Until the six-months immediately preceding the maturity date of the applicable series of Notes, each series of Notes is convertible only upon the occurrence of certain events and during certain periods, as set forth in the Indentures. The Notes will be convertible into cash, shares of the Company’s common stock (plus, if applicable, cash in lieu of any fractional share), or a combination of cash and shares of the Company’s common stock, at the Company’s election. On or after the date that is six-months immediately preceding the maturity date of the applicable series of Notes until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert such Notes at any time.
It is the Company’s intent and policy to settle all conversions through combination settlement. The initial conversion rate is 13.26, 8.96, and 8.21 shares of common stock per $1,000 principal amount for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively, which is equivalent to an initial conversion price of approximately $75.43, $111.66, and $121.84 per share of the Company’s common stock for the 2025 Notes, 2027 Notes, and 2028 Notes, respectively. The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. In addition, holders of the Notes who convert their Notes in connection with a “make-whole fundamental change” (as defined in the Indenture), will, under certain circumstances, be entitled to an increase in the conversion rate.​
If the Company undergoes a “fundamental change” (as defined in the Indenture), holders of the Notes may require the Company to repurchase for cash all or part of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest.​
Based on the closing price of our common stock of $58.00 on March 31, 2020, the if-converted values on our Notes do not exceed the principal amount.​
Ranking of Convertible Notes
The Notes are the Company’s senior unsecured obligations and (i) rank senior in right of payment to all of its future indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to all of the Company’s future liabilities that are not so subordinated, unsecured indebtedness; (ii) are effectively junior to all of our existing and future secured indebtedness and other secured obligations, to the extent of the value of the assets securing that indebtedness and other secured obligations; and (iii) are structurally subordinated to all indebtedness and other liabilities of the Company’s subsidiaries.​
While the Notes are currently classified on the Company’s condensed consolidated balance sheets at March 31, 2020 as long-term, the future convertibility and resulting balance sheet classification of this liability will be monitored at each quarterly reporting date and will be analyzed dependent upon market prices of the Company’s common stock during the prescribed measurement periods. In the event that the holders of the Notes have the election to convert the Notes at any time during the prescribed measurement period, the Notes would then be considered a current obligation and classified as such.​
The Company allocates total transaction costs of the Notes to the liability and equity components based on their relative values. Transaction costs attributable to the liability component are amortized to interest expense over the term of the Notes, and transaction costs attributable to the equity component are netted with the equity component in stockholders’ equity. The following table summarizes the original transaction costs at the time of issuance for each set of Notes and the respective allocation to the liability and equity components:

The remaining period overcompany paid $590.2 million in cash on the acquisition date. Of the total consideration for cash, $585.0 million was allocated to the purchase consideration and $5.2 million was recorded as compensation within general and administrative expenses on the acquisition date due to accelerated vesting of legacy Thrive RSU and RSA awards that were cash-settled in connection with the acquisition.
The contingent consideration arrangement requires the Company to pay up to $450.0 million of additional cash consideration to Thrive’s former shareholders upon the achievement of two discrete events, FDA approval and CMS coverage, for $150.0 million and up to $300.0 million, respectively. The fair value of the contingent consideration arrangement at the acquisition date was $352.0 million. The fair value of the contingent consideration was estimated using a probability-weighted scenario based discounted cash flow model. This fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement as defined in ASC 820. The key assumptions are described in Note 7. Of the total fair value of the contingent consideration, $331.3 million was allocated to the consideration transferred, $6.4 million was allocated to the Company’s previous ownership interest in Thrive, and $14.3 million was deemed compensatory as participation is dependent on replaced unvested equity awards vesting which requires future service. Compensation expense related to the unamortized debt discountmilestones could be up to $18.2 million undiscounted and will be recognized in the future once probable and payable. As of March 31, 2021, there were no significant changes in the range of outcomes for the contingent consideration recognized as non-cash interesta result of the acquisition of Thrive, although the recognized amount increased by $2.9 million as a result of the passage of time.
The Company replaced unvested stock options, RSUs, and RSAs and vested stock options with a combination-date fair value of $197.0 million. Of the total consideration for replaced equity awards, $52.2 million was allocated to the consideration transferred and $144.8 million was deemed compensatory as it was attributable to post acquisition vesting. Of the total compensation related to replaced awards, $65.0 million was expensed on the acquisition date due to accelerated vesting of stock options in connection with the acquisition and $79.8 million relates to future services and will be expensed over the remaining service periods of the unvested stock options, RSUs, and RSAs on a straight-line basis. Including expense recognized for accelerated vesting of RSUs and RSAs described above, total expected stock-based compensation expense is 7.92 years, 6.96 years,$166.0 million, of which $86.2 million was recognized immediately to general and 4.80 yearsadministrative expenses in the condensed consolidated statement of operations due to accelerated vesting.
The fair value of the stock options assumed by the Company was determined using the Black-Scholes option pricing model. The fair value of the RSA and RSUs assumed by the Company was determined based on the average of the high and low market price of the Company's shares on the acquisition date. The share conversion ratio of 0.06216 was applied to convert Thrive’s outstanding equity awards for Thrive’s common stock into equity awards for shares of the Company’s common stock.

The company previously held a preferred stock investment of $12.5 million in Thrive and recognized a gain of approximately $30.5 million on the transaction within investment income, net on the Company’s consolidated statement of operations, which represented the adjustment of the Company’s historical investment to the acquisition date fair value. The fair value of the Company’s previous ownership in Thrive was determined based on the pro-rata share payout applied to the Company’s interest combined with the fair value of the Company’s share of the contingent consideration arrangement, as discussed above.

IPR&D represents the fair value assigned to research and development assets that have not reached technological feasibility. The primary basis for determining technological feasibility of these projects is obtaining regulatory approval to market the underlying product and expected commercial release. The amounts capitalized are accounted for as indefinite-lived intangible assets, subject to impairment testing, until completion or abandonment of the research and development efforts associated with the projects. The company recorded $1.25 billion of IPR&D related to a project associated with the development of an FDA approved blood-based, multi cancer screening test. The IPR&D asset was valued using the multiple-period excess earnings method approach, which involves significant unobservable inputs (Level 3 inputs). These inputs include projected sales, margin, required rate of return and tax rate, as well as estimates of achievement probability and timing related to the royalty and milestone obligations due to JHU, as described in Note 10.

We have developed some of the most impactful brands in cancer diagnostics, and we are currently working on the development of additional tests, for other types of cancer, with the goal of bringing new innovative cancer tests to patients throughout the world.
Acquisitions
On January 5, 2021, we completed the acquisition ("Thrive Merger") of Thrive Earlier Detection Corporation (“Thrive”). Thrive is a healthcare company dedicated to developing a blood-based, multi-cancer screening test. We intend to combine Thrive's expertise with our scientific capabilities, clinical organization and commercial infrastructure to establish us as a leading competitor in blood-based, multi-cancer screening.
On January 11, 2021, we acquired a worldwide exclusive license to the proprietary Targeted Digital Sequencing (“TARDIS”) technology from The Translational Genomics Research Institute (“TGen”), an affiliate of City of Hope. We intend to use the TARDIS technology to develop a test to detect small amounts of tumor DNA that may remain in patients’ blood after they have undergone initial treatment, known as minimal residual disease (“MRD”).
On April 14, 2021, we completed the acquisition of all of the outstanding equity interests of Ashion Analytics, LLC (“Ashion”; such transaction the “Ashion Acquisition”) from PMed Management, LLC (“PMed”), which is a subsidiary of TGen. Ashion is a Clinical Laboratory Improvement Amendments (“CLIA”) certified and College of American Pathologists (“CAP”) accredited sequencing lab based in Phoenix, Arizona and developed GEMExTra®, one of the most comprehensive genomic cancer tests available, and provides access to the whole exome, matched germline, and transcriptome sequencing capabilities.
On May 3, 2021, we acquired approximately 90% of the outstanding capital stock of PFS Genomics Inc. (“PFS”; such transaction, the “PFS Acquisition”), pursuant to a share purchase agreement. PFS is a healthcare company focused on personalizing treatment for breast cancer patients to improve outcomes and reduce unnecessary treatment. We expect this acquisition to expand our ability to help guide early stage breast cancer treatment through individualized radiotherapy treatment decisions.
Our Cologuard Test
Colorectal cancer is the second leading cause of cancer deaths in the United States (“U.S.”) and the leading cause of cancer deaths in the U.S.United States among non-smokers. In 2020 in the U.S.United States there are projected to be approximately 148,000 new cases of colorectal cancer and 53,000 deaths from colorectal cancer. It is widely accepted that colorectal cancer is among the most preventable, yet least prevented cancers.
Our CologuardCologuard® test is a non-invasive stool-based DNA (“sDNA”) screening test that utilizes a multi-target approach to detect DNA and hemoglobin biomarkers associated with colorectal cancer and pre-cancer. Upon approval by the U.S. Food and Drug Administration (“FDA”) in August 2014, our Cologuard test became the first and only FDA-approved sDNA non-invasive colorectal cancer screening test. Our Cologuard test is now indicated for average risk adults 45 years of age and older.
Our original premarket approval submission to the FDA for Cologuard included the results of our pivotal DeeP-C clinical trial that had over 10,000 patients enrolled at 90 sites in the U.S. and Canada. The results of our DeeP-C clinical trial for Cologuard were published in the New England Journal of Medicine in April 2014. The peer-reviewed study, “Multi-target Stool DNA Testing for Colorectal-Cancer Screening,” highlighted the performance of Cologuard in the trial population:​
Cancer Sensitivity: 92%
Stage I and II Cancer Sensitivity: 94%
High-Grade Dysplasia Sensitivity: 69%
Specificity: 87%​​
Our Oncotype DXIQ Tests
With our Oncotype IQ Genomic Intelligence Platform we are applying our world-class scientific and commercial expertise and infrastructure to lead the translation of clinical and genomic data into clinically actionable results for treatment planning throughout the cancer patient'spatient’s journey, from diagnosis to treatment selection and monitoring. Our Oncotype IQ Genomic Intelligence Platform is currently comprised of our flagship line of Oncotype DXDX® gene expression tests for breast, prostate and colon cancer, as well as Oncotype DX AR-V7 Nucleus Detect® test, a liquid-based test for advanced stage prostate cancer.
We believe ourIn October 2020, we announced the introduction of the Oncotype DX tests provide informationMAPTM Pan-Cancer Tissue test, which is a rapid, comprehensive tumor profiling panel that has the following benefits:
Improved Quality of Treatment Decisions. We believe our approach to genomic-based cancer analysis improves the quality of cancer treatment decisions by providing an individualized analysis of each patient’s tumor that is correlated to clinical outcome, rather than solely using subjective, anatomic and qualitative factors to determine treatments. Our Oncotype DX testsaids therapy selection for breast cancer, Ductal Carcinoma in Situ (“DCIS”), prostate cancer, and colon cancer have been analytically and clinically validated in multiple published studies. The Recurrence Score® results from our tests have been demonstrated to classify patients into recurrence risk categories different than classifications based primarily on clinical and pathologic features. Additionally, multiple decision impact studies conducted worldwide consistently show that the Recurrence Score result changes treatment decisions in more than 30% of patients. As a result, we believe our tests enable patients and healthcare providers to make more informed decisions about the risks and benefits of various treatments, and consequently design an individualized treatment plan.with advanced, metastatic, refractory, or recurrent cancer.

Improved Health Economics of Cancer Care. We believe that improving the quality of treatment decisions can result in significant economic benefits. The results of a number of clinical studies have demonstrated that by using the Oncotype DX Breast Recurrence Score® test, physicians and patients can better evaluate treatment options, such as whether a patient will or will not benefit from chemotherapy. Patients are benefited when (1) those who aren’t likely to benefit from chemotherapy avoid it and the associated chemotoxicities and (2) those who are likely to benefit from chemotherapy receive it resulting in reduced incidence of distant recurrences. These better clinical outcomes increase survival rates and also save the patient as well as the healthcare system significant costs.
International Business Background and Products
Prior to our combination with Genomic Health, we did not have international revenue. We now commercialize our Oncotype DXIQ tests internationally through employees in Canada, Japan and six European countries, as well as through exclusive distribution agreements. We have provided our Oncotype DXIQ tests in more than 90 countries outside of the United States. We do not offer our Cologuard test or COVID-19 testing outside of the U.S.
United States. Inclusion of our products in guidelines and quality measures will be critical to our international success. The Oncotype DX breast cancer test is recognized in international guidelines issued by the St. Gallen International Breast Cancer Expert Panel and European Society for Medical Oncology and has been included in certain guidelines and recommendations in England, Germany and Japan. We have obtained coverage for our invasive breast cancer test outside of the U.S., including coverage for certain patients in Canada, France, Spain, Germany, Italy, Ireland, Israel, Saudi Arabia, Switzerland, and the United Kingdom. We expect that broadening coverage and reimbursement for our Oncotype DX tests outside of the United States will take years.
Pipeline Research and Development
Our research and development efforts are focused on developing new products and enhancing existing products to address new cancer areas and expand the clinical utility and addressable patient populations for our existing tests. These development efforts may lead to a variety of possible new products, including risk assessment, screening and prevention, early disease diagnosis, adjuvant and/or neoadjuvant disease treatment, metastatic disease treatment selection and patient monitoring.
Through our collaboration with Mayo Foundation for Medical Education and Research, we have successfully performed validation studies on multiple types of cancer using tissue, blood and other samples. We are currently focusing our research and development efforts on building a pipeline of potential future products and services with a focus on improving Cologuard's performance characteristics and on developing blood or other fluid-based (“liquid biopsy”) tests. We expect to advance liquid biopsy through biomarker discovery and validation in tissue, blood, or other fluids.
fluids and to leverage recent business development activities to accelerate our leadership in earlier cancer detection and treatment guidance. We are pursuing the following opportunities:
Colon Cancer Screening. We are seeking opportunities to improve upon Cologuard’sour Cologuard test’s performance characteristics. In October 2019, we and Mayo presented at the American College of Gastroenterology’s 2019 Annual Scientific Meeting findings from a blinded-case control study showing enhanced colorectal cancer and advanced adenoma detection using newly discovered methylation biomarkers and hemoglobin.biomarkers. To establish the performance of the novelan enhanced multi-target stool DNA test, we recently launched the BLUE-C study, a multi-center, prospective study. We expect to enroll more than 10,000 patients 40 years of age and older in theour multi-center, prospective BLUE-C study. The timing of any such enhancements to our Cologuard test is unknown and would be subject to FDA approval. We are also working to develop a blood-based screening test for colorectal cancer.

We intend to combine Thrive's expertise with our scientific capabilities, clinical organization and commercial infrastructure to establish us as a leading competitor in blood-based, multi-cancer screening.
Hepatocellular Carcinoma (HCC) Test Development. We are currently seeking to developdeveloping a blood-based biomarker test to serve as an alternative to ultrasound and alpha-fetoprotein (“AFP”) for use in HCC testing. HCC is the most common type of liver cancer. Our goal is to developprovide a patient-friendly test that performs better than the current standard of care.guideline-recommended testing options. In November 2019, we released the results of a 443-patient450-patient study which demonstrated 80% overall sensitivity for HCC at 90% specificity with a novel combination of six blood-based biomarkers for HCC. The study also showed 71% sensitivity for early stageearly-stage HCC at 90% specificity. The study compared performance to the AFP test, which demonstrated 45% sensitivity at 90% specificity for early stage HCC. We currently expect to offer our test to select offices in the second quarter of 2021.
Minimal Residual Disease (“MRD”) Test Development. In Vitro Device (IVD) Version of Oncotype DX Breast Cancer Test. We believe IVD versions of our  Oncotype DX products that can be performed locally may open up additional international opportunities.January 2021 we acquired an exclusive license to the TGen proprietary TARDIS technology. We are currently developing an IVD versionseeking to utilize this compelling and technically distinct approach to develop a test to detect small amounts of tumor DNA that may remain in patients’ blood after they have undergone initial treatment. In a study published in Science Translational Medicine, TARDIS demonstrated high accuracy in assessing molecular response and residual disease during neoadjuvant therapy to treat breast cancer. TARDIS achieved up to 100-fold improvement beyond the Oncotype DX Breast Recurrence Score test and may explore additional IVD versionscurrent limit of circulating tumor DNA detection. We intend to expand our Oncotype DX tests.precision oncology business to become a leader in minimal residual disease testing, which will leverage our existing foundation to deliver better solutions to patients navigating cancer.
Development Studies for Oncotype DX Products. We may also conduct or fund clinical studies that could support additional opportunities for our Oncotype DX products. For example, we may exploreare exploring clinical studies to expand the use of genomic testing to address additional populations, including higher-risk patients.
We may also use a number of other technologies across various development programs and product implementations. While early-stage cancer continues to be our main focus, we believe we also have an opportunity to expand our business further along the patient’s cancer journey, both through our research and development process and strategic collaborations.
AcquisitionsResearch and development, which includes our clinical study programs, accounts for a material portion of our operating expenses. As we seek to enhance our current product portfolio and expand our product pipeline by developing additional cancer screening and diagnostic tests, we expect that our research and development expenditures will continue to increase.

COVID-19 Testing Business
In late March 2020, we completedbegan providing COVID-19 testing. We have partnered with various customers, including the acquisitionState of allWisconsin Department of Health Services, to administer testing. Customers are responsible for employing trained personnel to collect specimens. Specimens are sent to our laboratory in Madison, Wisconsin, where we run the assay in our laboratories and provide test results to ordering providers. In light of the outstanding equity interests of Paradigm Diagnostics, Inc. (“Paradigm”)uncertainty surrounding the COVID-19 pandemic, we intend to periodically reassess our COVID-19 testing business. As the pandemic abates and Viomics, Inc. (“Viomics”), two privately held companies basedmore people receive vaccinations, we expect declining demand for COVID-19 testing.
2021 Priorities
Our top priorities for 2021 are to (1) get more people tested, (2) advance new solutions, and (3) enhance our customer experience.
Get More People Tested
We are committed to delivering critical answers to patients by getting more people tested with our Cologuard and Oncotype IQ tests. We will also continue to provide COVID-19 testing to support our employees and to improve the country's testing capacity.
Advance New Solutions
In 2021, we are focused on advancing new solutions to provide answers to patients throughout their cancer journeys. We plan to continue investing in Phoenix, Arizona. Paradigm provides comprehensive genomic-based profiling tests that assistongoing and additional clinical trials to support our product development efforts in enhancing existing products. We also plan to bring new products to patients and providers as further discussed in the diagnosisPipeline Research and therapy recommendationsDevelopment section above.
Enhance Our Customer Experience
Another priority for late-stage cancer. Viomics provides a platform2021 is to enhance our customer experience. To establish long-term relationships with patients and providers, we plan to improve customer communications and create new ways to personalize their experiences. Our goal is to become the cancer diagnostic provider of choice for identificationproviders and patients.

Coronavirus (“COVID-19”) PandemicOperations
The spread of COVID-19 has affected many segments of the global economy, including the cancer screening and diagnostics industry. The COVID-19 outbreak, which the World Health Organization has classified as a pandemic, has prompted governments and regulatory bodies throughout the world to issue “stay-at-home” or similar orders, and enact restrictions on the performance of “non-essential” services, public gatherings and travel. Health systems, including in key markets where we operate, have been, or may be, overwhelmed with high volumes of patients suffering from COVID-19.
The pandemic and related precautionary measures began to materially disrupt our business in March 2020 and may continue to disrupt our business for an unknown period of time. As a result, we anticipate significantthe pandemic has continued to have an impact toon our 20202021 operating results, including our revenues, margins, and margins,cash utilization, among other measures.
Beginning in March 2020, we undertook temporary precautionary measures intended to help minimize the risk of the virus to our employees, including temporarily requiring most employees to work remotely, suspending field-based, face-to-face interactions by our sales force, pausing all non-essential travel worldwide for our employees, and limiting employee attendance at industry events and in-person work-related meetings, to the extent those events and meetings are continuing. We may take additional measures, any of which could negatively affect our business. We are also providing COVID-19 testing. We have received a letter from the U.S. Food and Drug Administration (FDA) granting us Emergency Use Authorization for a nasal-swab based test for the detection of SARS-CoV-2, the virus that causes COVID-19.
Due to social distancing, stay-at-home orders, and other actions taken in response to COVID-19, there has beenwas a significant and widespread decline in standard wellness visits and preventive services. That decline has negatively impacted Cologuard test orders in our Screening business, notwithstandingservices beginning at the availabilityend of alternative ordering channels such as telehealth. Additionally, patients have been completing tests at a lower rate. Cologuard test orders declined 63 percent year-over-year during the first 20 days of April 2020. We saw a slight recovery in the last 10 days of April 2020, with orders declining 47 percent year-over-year. We expect that Cologuard orders and revenues will be negatively impacted in the second quarter of 2020 and beyond.

After delivering strong results in the first quarter the Precision Oncology business is also starting to see weakening underlying conditions because of COVID-19, more notably in the U.S. prostate business and in certain international geographies.2020. We expect the widespread decrease in preventive services, such as mammograms and prostate cancer screenings, to negatively impact Precision Oncology test volumes in the coming months due to the typical lag between cancer screening and genomic test ordering.
Despite our efforts, the ultimate impact of COVID-19 depends on factors beyond our knowledge or control, including the duration and severity of the outbreak as well as third-party actions taken to contain its spread and mitigate its public health effects.
2020 Priorities
As a result of COVID-19 and its impact to our business, we have re-prioritized our goals for 2020 with a focus on serving patients who continue to need the healthcare services we provide while aligning our cost structure with the anticipated lower sales volumes and revenues. Our top priorities for 2020 are (1) get people tested, (2) take care of our customers, and (3) preserve financial strength.
Get People Tested
Business continuity plans are in place at all of our sites to help sustain operations and ensure continuity of services for patients during this unprecedented time. Despite the COVID-19 pandemic, many people still need to be screened for colorectal cancer, and treated for breast, colon, and prostate cancers. Our lab facilities presently remain operational so that we can continue to process results of our Cologuard and Oncotype DX tests.
We are also providing COVID-19 testing after the FDA granted us Emergency Use Authorization for a nasal-swab based test for the detection of COVID-19.
Take Care of our Customers
Due to social distancing, stay-at-home orders, and other actions taken in response to COVID-19, there has been a significant and widespread decline in standard wellness visits and preventive services. We have takentook steps to limit exposure to COVID-19 based on recommendations from government and health agencies, including suspendinglimiting field-based, face-to-face interactions by our sales force. The sales team will serve healthcaredecline in field-based, face-to-face interactions with health care providers via telephonenegatively impacted Cologuard test orders beginning in March 2020 in our Screening business, notwithstanding the availability of alternative ordering channels such as telehealth. Order volumes recovered over the course of 2020 and online technologies until it is safeby the first quarter of 2021 exceeded pre-pandemic levels. Our Precision Oncology business started to return tosee weakening underlying conditions in April 2020 because of COVID-19. The widespread decrease in preventive services, including mammograms and prostate cancer screenings, negatively impacted Precision Oncology test volumes beginning in May 2020 and continuing throughout the field.
Preserve Financial Strength
In order to minimize the adverse impacts to our business and operations thus far and anticipated for the remainderthird quarter of 2020 due to the COVID-19typical lag between cancer screening and genomic test ordering. We began to see orders recovering in the fourth quarter of 2020 to near pre-pandemic levels, and that recovery continued in the first quarter of 2021. While we have seen recovery in our Screening and Precision Oncology businesses, the impact of the pandemic is uncertain and subject to factors beyond our control. As a result of the pandemic, we have initiated proactivecontinued to provide COVID-19 testing, the revenue from which has partially offset the pandemic’s impact on our Screening and Precision Oncology testing revenue.

We expect to adjust our precautionary measures at our various locations based on local recovery levels and applicable governmental regulations. For example, a portion of the Company’s and Pfizer’s sales force has recommenced field-based interactions, although access to achieve cost savings. Actionshealthcare providers remains limited and the resumption of normal activities is expected to be gradual. Our business could be negatively affected if we take excessive, ineffective or inadequate precautions.
As our Screening and Precision Oncology businesses have continued to recover throughout the first quarter of 2021, we have taken includecontinued to plan for future growth through investing in our existing operations and through the reduction of base pay for our chief executive officer to effectively zero, elimination of the Board of Directors annual cash retainer, reducing base salaries for our executive team, and reducing the quarterly sales commissions. We implemented a workforce reduction, involuntary furloughs, work schedule reductions, as well as a voluntary furlough program. Additionally, we are reducing our investments in marketing and other promotional activities, pausing certain clinical trial activities, reducing travel and professional services, and delaying or terminating certain capital projects. We also expect a reduction in certain volume based cost of goods sold expenses consistent with the reduction in revenue. We estimate that these items will contribute over $400.0 million of cost savings in 2020, with the majority in reduced operating expense. If we see a faster-than-expected recovery from COVID-19 and re-acceleration of growth, cost savings may be materially lower, as we would invest to support that growth.
Results of Operations​acquisitions further discussed above.
We have generated significant losses since inception and, as of March 31, 2020,2021, we had an accumulated deficit of approximately $1.2$2.08 billion. We expect to continue to incur losses for the near future, and it is possible we may never achieve profitability. As mentioned in further detail above, we expect the recent outbreak of COVID-19 will have an adverse impact on our operations in 2020. ​

Revenue. Our revenue is primarily generated by our laboratory testing services from our Cologuard, Oncotype IQ, and COVID-19 tests. Our Screening revenue, which primarily includes laboratory service revenue from our Cologuard test, was $240.3 million and $219.5 million for the three months ended March 31, 2021 and 2020, respectively. The increase was primarily due to an increase in the number of completed Cologuard tests. Our Precision Oncology revenue, which primarily includes laboratory service revenue from our global Oncotype DXproducts, was $129.4 million and $128.4 million for the three months ended March 31, 2021 and 2020, respectively. The increase was primarily due to an increase in the number of completed Oncotype IQ tests. For the three months ended March 31, 2020 and 2019,2021, we also generated Screening revenue of $219.5$32.3 million and $162.0 million, respectively. Screening includes laboratory servicein revenue from Cologuard and revenue from Biomatrica products. The increase in revenue was primarily due to an increase in completed Cologuard tests during the current period. For the three months ended March 31, 2020, we generated Precision Oncology revenue of $128.4 million. Precision Oncology includes laboratory service revenue from global Oncotype DX and Paradigm products. For the three months ended March 31, 2020, the Company’s revenue was adversely impacted by theour COVID-19 outbreak as further discussed above.testing.
Our cost structure. Our selling, general and administrative expenses consist primarily of non-research personnel salaries, office expenses, professional fees, sales and marketing expenses incurred in support of our commercialization efforts and non-cash stock-based compensation.
Cost of sales includes costs related to inventory production and usage, shipment of collection kits and tissue samples, royalties and the cost of services to process tests and provide results to healthcare providers.
We expect that gross marginrevenue and cost of sales for our services will continue to fluctuate and be affected by the test volume of our products, our operating efficiencies, patient adherence rates, payer mix, the levels of reimbursement, and payment patterns of payers and patients.
Cost of sales (exclusive of amortization of acquired intangible assets). Cost of sales increased to $110.0 million for the three months ended March 31, 2021 compared to $81.6 million for the three months ended March 31, 2020 from $42.8 million for the three months ended March 31, 2019.2020. The increase in cost of sales is primarily due to the increasesan increase in production costs from an increase in completed Cologuard and Oncotype IQ tests and duecosts incurred from our COVID-19 testing including a charge of $6.0 million for a reserve of excess inventory related to our COVID-19 testing. We also incurred an increase in personnel expenses to support the completionincrease in volume and future growth of the combination with Genomic Health in November 2019.our tests.

Liquidity and Capital Resources​Resources
We have financed our operations since inception primarily through public offerings of our common stock and convertible debt and through revenue generated by the sale of theour Cologuard test, and since the completion of our Genomic Health combination, of Oncotype DXIQ tests. As of March 31, 2020,2021, we had approximately $701.1 million$1.10 billion in unrestricted cash and cash equivalents and approximately $530.1$274.2 million in marketable securities.
The majority of our investments in marketable securities consist of fixed income investments, and all are deemed available-for-sale. The objectives of this portfolio are to provide liquidity and safety of principal while striving to achieve the highest rate of return. Our investment policy limits investments to certain types of instruments issued by institutions with investment grade credit ratings and places restrictions on maturities and concentration by type and issuer.
Net cash used in operating activities was $77.2 million for the three months ended March 31, 2021 compared to cash use of $49.8 million for the three months ended March 31, 2020 compared to $74.2 million for the three months ended March 31, 2019.2020. The principal use ofincrease in cash used in operating activities for the three months ended March 31, 20202021 was primarily due to the increase in operating expenses incurred to prepare for future growth in our business and 2019an increase in costs incurred to process our tests due to the increase in volume. This was partially offset by an increase in cash receipts as a result of an increase in revenue. The increase in revenue was driven by an increase in completed Cologuard, Oncotype IQ, and COVID-19 tests.

The cash provided by financing activities for the three months ended March 31, 2019 was primarily the result of proceeds of $729.5 million from our issuance of Convertible Notes with a maturity date of March 15, 2027 (the “2027 Notes”, and, collectively with the 2025 Notes and 2028 Notes, the “Notes”), and we used $493.4 million of cash to settle a portion of the 2025 Notes. In addition, during the three months ended March 31, 2020 we received proceeds of $4.3 million from the exercise of stock options.

$75.0 million on the closing date. On May 3, 2021, we completed the PFS Acquisition, under which we acquired 90% of PFS for cash consideration of $30.6 million, which was paid at closing.
We expect that cash and cash equivalents and marketable securities on hand at March 31, 20202021 will be sufficient to fund our current operations for at least the next twelve months including the cash consideration paid as part of the Ashion Acquisition and PFS Acquisition in April 2021 and May 2021, respectively, based on current operating plans. However, we may need to raise additional capital to fully fund our current strategic plan, which includes successfully commercializing our Cologuard test and Oncotype DXIQ products and developing a pipeline of future products. Additionally, we may enter into transactions to acquire other businesses, products, services, or technologies as part of our strategic plan. If we are unable to obtain sufficient additional funds to enable us to fund our operations through the completion of such plan, our results of operations and financial condition would be materially adversely affected, and we may be required to delay the implementation of our plan and otherwise scale back our operations. Even if we successfully raise sufficient funds to complete our plan, there is no certainty that we cannot assure that our business will ever generatebe successful in generating sufficient cash flow from operations or achieving and maintaining profitable operations in the future to become profitable.​
The spread of COVID-19 and measuresenable us to prevent further spread, have significantly disruptedmeet our business, and may continue to disrupt our business for an unknown period of time. The full impact of the outbreak is uncertain at this time and continues to evolve globally. We do not yet know the extent to which COVID-19 will negatively impact our financial results or liquidity. The outbreak has already disrupted our operations,obligations as well as the operations and behaviors of healthcare providers, patients and suppliers. To the extent that healthcare providers, patients and suppliers continue to be adversely impacted by the pandemic, we could see a material interruption our operations and liquidity. Management continues to monitor and assess the evolving developments with respect to COVID-19.they come due.
A table reflecting certain of our specified contractual obligations as of December 31, 20192020 was provided in the Management’s Discussion and Analysis of Financial Condition and Results of Operation of our 20192020 Form 10-K. During the three months ended March 31, 2020, we issued $1,150.0 million in aggregate principal amount of 0.375% Convertible Notes that will mature on March 1, 2028. The holders of the Notes may convert prior to September 1, 2027 only under certain circumstances and may convert at any time after September 1, 2027. The Notes accrue interest at a fixed rate of 0.375% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2020. Of the cash received upon issuance of the 2028 Notes, approximately $150.1 million was used to repay a portion of the outstanding principal balance and accrued interest of the 2025 Notes held by certain Noteholders. Upon repayment of such portion of the outstanding principal balance of the 2025 Notes, there was $315.0 million in aggregate principal balance remaining under the 2025 Notes. See Note 15 of the condensed consolidated financial statements included in this Quarterly Report for further details. With the exception of this item, thereThere were no material changes outside the ordinary course of our business in our specified contractual obligations during the three months ended March 31, 2020.​2021.
Critical Accounting Policies and Estimates​Estimates
Management’s discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United StatesU.S. (“GAAP”). The preparation of these financial statements requires us to make estimates and assumptions that affect the amounts reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of thein our condensed consolidated financial statements as well as the reported revenues and expenses during the reporting periods.accompanying notes. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, tax positions and stock-based compensation.judgments. We base our estimates on historical experience and on various other factors that are believed to be appropriate under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
OurWhile our significant accounting policies are more fully described in Note 1 of our financial statements included in our 20192020 Form 10-K, as well as our Management’s Discussion and Analysis of Financial Condition and Results of Operations on our 20192020 Form 10-K. There10-K, we believe that the following accounting policies and judgments are most critical to aid in fully understanding and evaluating our reported financial results. Other than the adoption of Accounting Standards Update 2020-06 fully discussed in Note 9 of our condensed consolidated financial statements in this Quarterly Report on Form 10-Q, there have not been any significant changes to our critical accounting policies and estimates during the three months ended March 31, 2020.​2021.

Revenue Recognition. We recognize revenue on theRevenues are recognized when we release of a test result to anthe ordering healthcare provider, for tests performed based on our estimate of thein an amount that reflects the consideration we will ultimatelyexpect to collect at the time the release is complete.in exchange for those services. The amount of revenue we recognize is based on the established billing rates less contractual and other adjustments, which yields the constrained amount that we expect to ultimately collect. We determine the amount we expect to ultimately collect, on a per-payer or per-agreement basis, using historical collections, established reimbursement rates and other adjustments. The expected amount is typically lower than, if applicable, the agreed-
53

uponagreed-upon reimbursement amount due to several factors, such as the amount of any patient co-payments, out-of-network payers, the existence of secondary payers and claim denials. The consideration derived from our contracts is fixed when we contract with a direct bill payer. Our ability to collect is not contingent on the customer’s ability to collect through their downstream billing efforts.
In the case of some of our laboratory service agreements (“LSAs”) with various organizations, the right to bill and collect exists prior to the receipt of a specimen and release of a test result to the ordering healthcare provider, which results in deferred revenue. The deferred revenue balance is generally relieved upon the release of the applicable patient’s test result to the ordering healthcare provider or as of the date the customer has surpassed the window of time in which they are able to exercise their rights for testing services. We believe these points in time represent our fulfillment of our obligations to the customer.
The quality of our billing operations, most notably those activities that relate to obtaining the correct information in order to bill effectively for services provided, directly impacts the collectability of our receivables and revenue estimates. As such, we continually assess the state of our order to cash operations in order to identify areas of risk and opportunity that allow us to appropriately estimate receivables and revenue. Upon ultimate collection, the aggregate amount received from payers and patients where reimbursement was estimated is compared to previous collection estimates and, if necessary, the contractual allowance is adjusted. Finally, should we later determine the judgments underlying estimated collections change, our financial results could be negatively impacted in future quarters.
Convertible Notes. We account for convertible debt instruments that may be settled in cash or equity upon conversion by separating the liabilityBusiness Combinations and equity components of the instruments in a manner that reflects our nonconvertible debt borrowing rate. In February 2020 we issued the 2028 Notes of $1,150.0 million in aggregate principal amount of 0.375% Convertible Notes with a maturity date of March 1, 2028. As part of that issuance, we settled approximately $100.0 million in outstanding 2025 Notes. We determined the carrying amount of the liability component of the 2028 Notes by using assumptions that market participants would use in pricing a debt instrument, including market interest rates, credit standing, yield curves and volatilities. Determining the fair value of the debt component requires the use of accounting estimates and assumptions. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the debt component, and the associated non-cash interest expense.​
For the February 2020 offering, we allocated $346.6 million, net of tax, to the equity component of the convertible debt instrument. That equity component is treated as a discount on the liability component of the Notes, which is amortized over the eight-year term of the 2028 Notes using the effective interest rate method. In addition, debt issuance costs related to the 2028 Notes was $24.4 million. We allocated the costs to the liability and equity components of the 2028 Notes based on their relative values. The debt issuance costs allocated to the liability component are being amortized over the life of the 2028 Notes as additional non-cash interest expense. The transaction costs allocated to the equity component are netted with the equity component of the convertible debt instrument in stockholders’ equity.​
Business Combinations.Asset Acquisitions. Business Combinations are accounted for under the acquisition method in accordance with ASCAccounting Standards Codification (“ASC”) 805, Business Combinations. The acquisition method requires identifiable assets acquired and liabilities assumed and any non-controlling interest in the business acquired be recognized and measured at fair value on the acquisition date, which is the date that the acquirer obtains control of the acquired business. The amount by which the fair value of consideration transferred as the purchase price exceeds the net fair value of assets acquired and liabilities assumed is recorded as goodwill. Acquisitions that do not meet the definition of a business combination under the ASC are accounted for as asset acquisitions. Asset acquisitions are accounted for by allocating the cost of the acquisition to the individual assets acquired and liabilities assumed on a relative fair value basis. Goodwill is not recognized in an asset acquisition with any consideration in excess of net assets acquired allocated to acquired assets on a relative fair value basis. Transaction costs are expensed in a business combination and are considered a component of the cost of the acquisition in an asset acquisition.
In March 2020, we recognized goodwillImpairment of $29.7 million from the acquisitions of Paradigm and Viomics.Long-Lived Assets. We evaluate goodwillthe fair value of long-lived assets, which include property, plant and equipment, intangible assets, and investments in privately held companies, for impairment on an annual basiswhenever events or more frequently should an event or changechanges in circumstance occur that indicatescircumstances indicate that the carrying amount is in excessamounts of the fair value.

Item 3. Quantitative and Qualitative Disclosures About Market Risk​Risk
Interest Rate Risk
Our exposure to market risk is principally confined to our cash, cash equivalents and marketable securities. We invest our cash, cash equivalents, and marketable securities in securities of the U.S. governments and its agencies and in investment-grade, highly liquid investments consisting of commercial paper, bank certificates of deposit, and corporate bonds, which as of March 31, 20202021 and December 31, 20192020 were classified as available-for-sale. We place our cash, cash equivalents, restricted cash, and marketable securities with high-quality financial institutions, limit the amount of credit exposure to any one institution, and have established investment guidelines relative to diversification and maturities designed to maintain safety and liquidity.
Based on a hypothetical ten percent adverse movement in interest rates, the potential losses in future earnings, fair value of risk-sensitive financial instruments, and cash flows are immaterial, although the actual effects may differ materially from the hypothetical analysis. While we believe our cash, cash equivalents, restricted cash, and marketable securities do not contain excessive risk, we cannot provide absolute assurance that, in the future, our investments will not be subject to adverse changes in market value. In addition, we maintain significant amounts of cash, cash equivalents, restricted cash, and marketable securities at one or more financial institutions that are in excess of federally insured limits. Given the potential instability of financial institutions, we cannot provide assurance that we will not experience losses on these deposits. We do not utilize interest rate hedging agreements or other interest rate derivative instruments.
A hypothetical ten percent change in interest rates would not have a material adverse impact on our future operating results or cash flows. All of our significant interest-bearing liabilities bear interest at fixed rates and therefore are not subject to fluctuations in market interest rates; however, because these interest rates are fixed, we may be paying a higher interest rate, relative to market, in the future if circumstances change.
Foreign Currency Risk
Substantially all of our revenues are recognized in U.S. dollars, although a growing percentagesmall portion is denominated in foreign currency as we continue to expand into markets outside of the U.S. Certain expenses related to our international activities are payable in foreign currencies. As a result, factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets will affect our financial results.
Prior to 2019, the functional currency for each of our international subsidiaries was its local currency. For 2019 our international subsidiaries use the U.S. dollar as the functional currency, resulting in us not being subject to gains and losses from foreign currency translation of the subsidiary financial statements. In September 2017, Genomic Health (now a wholly owned subsidiary) started entering into forward contracts to mitigate the impact of adverse movements in foreign exchange rates related to the re-measurement of monetary assets and liabilities and hedge our foreign currency exchange rate exposure. As of March 31, 2020,2021, we had open foreign currency forward contracts with notional amounts of $14.3$26.4 million. Although the impact of currency fluctuations on our financial results has been immaterial in the past, there can be no guarantee that the impact of currency fluctuations related to our international activities will not be material in the future.

Item 4. Controls and Procedures​Procedures
As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based upon that evaluation, our principal executive officer and our principal financial officer concluded that, as of March 31, 2020,2021, our disclosure controls and procedures were effective. Disclosure controls and procedures enable us to record, process, summarize and report information required to be included in our Exchange Act filings within the required time period. Our disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed by us in the periodic reports filed with the SEC is accumulated and communicated to our management, including our principal executive, financial and accounting officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

In November 2019, the CompanyJanuary 2021, we acquired all of the outstanding capital stock of Genomic HealthThrive (see Note 16 to17 of the accompanying condensed consolidated financial statements for additional information). As of March 31, 2020,2021, management is in the process of evaluating and integrating the internal controls of Genomic HealthThrive into the Company’s existing operations. Other than the controls enhanced or implemented to integrate the Genomic HealthThrive business, there have been no significant changes in the Company’s internal controlscontrol over financial reporting during the quarter ended March 31, 20202021 that have materially affected, or are reasonably likely to materially affect, the Company’sour internal controlscontrol over financial reporting.

Part II - Other Information
Item 1. Legal Proceedings​Proceedings
From time to time we are a party to various legal proceedings arising in the ordinary course of our business. Legal proceedings, including litigation, government investigations and enforcement actions could result in material costs, occupy significant management resources and entail civil and criminal penalties.
The United States Department of Justice (“DOJ”)information called for by this item is investigating Genomic Health’s compliance with the Medicare Date of Service billing regulation. In March 2017, Genomic Health received a civil investigative demand (“CID”) from the U.S. Attorney’s Office for the Eastern District of New York in connection with this matter and has produced specific documents in responseincorporated by reference to the CID. In July 2019 and January 2020, Genomic Health received additional subpoenas frominformation in Note 14 of the DOJ relatedNotes to Condensed Consolidated Financial Statements included in Part I of this inquiry and we are cooperating with those requests. An adverse outcome could include our being required to pay treble damages, incur civil and criminal penalties, paying attorney’s fees, entering into a corporate integrity agreement, being excluded from participation in government healthcare programs, including Medicare and Medicaid, and other adverse actions that could materially and adversely affect our business, financial condition and results of operations.Quarterly Report on Form 10-Q.

Item 1A. Risk Factors​Factors
We operate in a rapidly changing environment that involves a number of risks that could materially affect our business, financial condition or future results, some of which are beyond our control. In addition to the other information set forth in this report, the risks and uncertainties that we believe are most important for you to consider are discussed in Part I, “Item 1A. Risk Factors” in the 20192020 Form 10-K and in Part II, “Item 1A. Risk Factors” in our subsequently filed Quarterly Reports on Form 10-Q. Other than the factors set forth below, thereThere have been no material changes to the risk factors described in the 20192020 Form 10-K and in subsequently filed Quarterly Reports on Form 10-Q.
The recent COVID-19 or coronavirus outbreak has and may further materially and adversely affect our business and financial results.
The COVID-19 outbreak, which the World Health Organization has classified as a pandemic, together with related precautionary measures, began to materially disrupt our business in March 2020 and may continue to disrupt our business for an unknown period of time. As a result, we anticipate significant impact to our 2020 operating results, including our revenues, margins, and cash utilization, among other measures.
Beginning in March 2020, we undertook temporary precautionary measures intended to help minimize the risk of the virus to our employees, including temporarily requiring most employees to work remotely, suspending field-based, face-to-face interactions by our sales force, pausing all non-essential travel worldwide for our employees, and limiting employee attendance at industry events and in-person work-related meetings, to the extent those events and meetings are continuing. Our commercial partner for Cologuard, Pfizer, Inc. (“Pfizer”) has taken similar precautions, including suspending face-to-face interactions between sales representatives and healthcare providers. We may take additional measures, any of which could negatively affect our business.
Due to social distancing, stay-at-home orders, and other actions taken in response to COVID-19, there has been a significant and widespread decline in standard wellness visits and preventive services. That decline has negatively impacted Cologuard test orders in our Screening business, notwithstanding the availability of alternative ordering channels such as telehealth. We expect that Cologuard orders and revenues will be negatively impacted in the second quarter of 2020 and beyond then.
Our Precision Oncology business is also starting to see weakening underlying conditions because of COVID-19, more notably in the U.S. prostate business and in certain international geographies. We expect the widespread decrease in preventive services, such as mammograms and prostate cancer screenings, to negatively impact Precision Oncology test volumes in the coming months due to the typical lag between cancer screening and genomic test ordering.
57

The COVID-19 pandemic has materially impacted our business, and may continue to impact our business for an unknown period of time. Such impacts may include the following:
Both our and Pfizer’s sales teams have been, and for an extended period of time may continue to be, prevented from interacting with healthcare providers, and therefore, also prevented from engaging in various types of healthcare provider education activities as contemplated by our and Pfizer’s Cologuard promotion agreement;
We and Pfizer may not be able to perform healthcare provider education and other activities contemplated by the promotion agreement and therefore may not realize the expected benefits from the promotion agreement. Before the pandemic, we were already discussing potential modifications of the promotion agreement with Pfizer, and those discussions have continued and have been affected by the pandemic. Any failure to conclude those negotiations in a manner satisfactory to us and to Pfizer could, among other things, have an adverse impact on our relationship with Pfizer or result in either party electing to terminate the agreement early;
Healthcare providers or patients have canceled, and for an extended period of time may continue to cancel, non-emergency appointments and procedures, contributing to a decline in orders for our products or services;
Restrictions on travel, commerce and shipping may prevent patients and pathologists from shipping samples to our clinical laboratories;
Illnesses, quarantines, financial hardships, restrictions on travel, commerce and shipping, or other consequences of the pandemic, may disrupt our supply chain or other business relationships, and we or other parties may assert rights under force majeure clauses to excuse performance;
We have experienced, and for an extended period of time may continue to experience, reduced volumes at our clinical laboratories and we may need to suspend operations at some or all of our clinical laboratories;
We have taken, and may take additional, cost cutting measures, which may hinder our efforts to commercialize our products or delay the development of future products and services. We might not realize all of the cost savings we expect to achieve as a result of those efforts;
We and our partners have postponed or cancelled clinical studies, which may delay or prevent our launch of future products and services;
Our workforce, much of which has been asked to work remotely in an effort to reduce the spread of COVID-19, may be infected by the virus or otherwise distracted; and
A combination of factors, including infection from the virus, supply shortfalls, and inability to obtain or maintain equipment, could adversely affect our lab capacity and our ability to meet the demand for our testing services.
Despite our efforts to manage and remedy these impacts to the Company, their ultimate impact also depends on factors beyond our knowledge or control, including the duration and severity of the outbreak as well as third-party actions taken to contain its spread and mitigate its public health effects.
Additionally, the anticipated economic consequences of the COVID-19 pandemic have adversely impacted financial markets, resulting in high share price volatility, reduced market liquidity, and substantial declines in the market prices of the securities of most publicly traded companies, including Exact Sciences. Volatile or declining markets for equities could adversely affect our ability to raise capital when needed through the sale of shares of common stock or other equity or equity-linked securities. If these market conditions persist when we need to raise capital, and if we are able to sell shares of our common stock under then prevailing market conditions, we might have to accept lower prices for our shares and issue a larger number of shares than might have been the case under better market conditions, resulting in significant dilution of the interests of our stockholders.
We currently offer COVID-19 testing, but there can be no assurance that we will be able to successfully offer, perform or generate revenues from the test.
In late March 2020, we began providing COVID-19 testing. We have received a letter from the U.S. Food and Drug Administration (FDA) granting us Emergency Use Authorization for a nasal-swab based test for the detection of SARS-CoV-2, the virus that causes COVID-19.
58

While we have entered into a limited number of contracts to provide COVID-19 testing and expect to pursue additional contracts, there can be no assurance that our efforts to offer and perform COVID-19 testing will be successful. The success of our test and our ability to generate revenues from COVID-19 testing will depend on a variety of factors, including:
the level of demand for COVID-19 testing, and the length of time for which that demand persists;
the availability of COVID-19 testing, from other laboratories;
acceptance of our COVID-19 testing in the medical community;
the emergence of other forms of COVID-19 testing (including antibody screening tests) and other collection methods, which healthcare providers and patients may prefer to our test;
the period of time for which the FDA will permit us to offer COVID-19 testing under an Emergency Use Authorization;
our ability to maintain regulatory approvals to perform and market COVID-19 testing and to respond to any changes in regulatory requirements;
the potential for supply disruptions and our reliance on certain single-source suppliers;
the potential for disruption in the delivery of patient samples to our laboratories;
the capacity of our laboratories to satisfy both COVID-19 testing and other testing demands;
the complexity of billing for, and collecting revenue for, our test;
healthcare provider and patient compliance with instructions for performing the nasal swab and providing samples to our laboratories;
our ability to maintain laboratory operations during the COVID-19 pandemic and to perform the test accurately and punctually; and
the ease of use of our ordering and reporting process.
Additionally, we have previously only offered cancer screening and diagnostic tests. The addition of COVID-19 testing may divert resources and distract management’s attention from other projects that may be more profitable or strategic. If we are unable to successfully provide COVID-19 testing while continuing to operate our existing screening and precision oncology business, our results of operations, financial position and reputation may suffer.
Our indebtedness could adversely affect our business, financial condition and results of operations and we may not be able to meet our payment obligations under such indebtedness.
As March 31, 2020, we had outstanding $2.2 billion of convertible notes and a $24.7 million construction loan. This level of debt could have significant consequences on our future operations, including:
increasing our vulnerability to adverse economic and industry conditions;
making it more difficult for us to meet our payment and other obligations;
making it more difficult to obtain any necessary future financing for working capital, capital expenditures, debt service requirements or other purposes;
requiring the dedication of a substantial portion of any cash flow from operations to service our indebtedness, thereby reducing the amount of cash flow available for other purposes, including capital expenditures;
placing us at a possible competitive disadvantage with competitors that are less leveraged than us or have better access to capital than we have; and
limiting our flexibility in planning for, or reacting to, changes in our business and the markets in which we compete.
Any of the above-listed factors could have an adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations under the convertible notes.
Our ability to meet our payment and other obligations under the convertible notes depends on our ability to generate significant cash flow in the future. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that future borrowings will be available to us, in an amount sufficient to enable us to meet our payment obligations under the convertible notes and to fund other
59

liquidity needs. If we are not able to generate sufficient cash flow to service our debt obligations, we may need to refinance or restructure our debt, including the convertible notes, sell assets, reduce or delay capital investments, or seek to raise additional capital. Our ability to implement one of these alternatives will depend on the capital markets, economic conditions, and our financial condition at such time. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations under the convertible notes, and such a default could cause us to be in default on any other currently existing or future outstanding indebtedness.10-K.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
On March 3, 2020,In January 2021, we completed the acquisitionsentered into an amendment to a services and license agreement with The Translational Genomics Research Institute, an affiliate of Paradigm and Viomics.City of Hope (“TGen”), pursuant to which we acquired a worldwide exclusive license to TGen’s proprietary Targeted Digital Sequencing (“TARDIS”) technology.
