EXACT SCIENCES CORPORATION

Notes to Condensed Consolidated Financial Statements

(Unaudited)

(1) ORGANIZATION AND BASIS OF PRESENTATION

Organization

Exact Sciences Corporation (“Exact” or the “Company”) was incorporated in February 1995. Exact is a molecular diagnostics company currently focused on the early detection and prevention of some of the deadliest forms of cancer. The Company has developed an accurate, non-invasive, patient-friendly screening test called Cologuard® for the early detection of colorectal cancer and pre-cancer, and is currently working on the development of tests for other types of cancer.

Basis of Presentation

The accompanying condensed consolidated financial statements, which include the accounts of Exact Sciences Corporation and those of its wholly owned subsidiaries, Exact Sciences Laboratories, LLC, Exact Sciences Finance Corporation, Exact Sciences Europe LTD, Beijing Exact Sciences Medical Technology Company Limited, 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, 2016 included in the Company’s Annual Report on Form 10-K (the “2016 Form 10-K”). 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, all adjustments (consisting only of adjustments of a normal and recurring nature) considered necessary for a fair presentation of the results of operations have been included. 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 2016 Form 10-K.  Management has evaluated subsequent events for disclosure or recognition in the accompanying financial statements up to the filing of this report.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of the Company’s wholly owned subsidiaries, Exact Sciences Laboratories, LLC, Exact Sciences Finance Corporation, Exact Sciences Europe LTD, Beijing Exact Sciences Medical Technology Company Limited, and variable interest entities. All significant intercompany transactions and balances have been eliminated in consolidation.

References to “Exact”, “we”, “us”, “our”, or the “Company” refer to Exact Sciences Corporation and its wholly owned subsidiaries.

Use of Estimates

The preparation of 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.  Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers cash on hand, demand deposits in bank, money market funds, and all highly liquid investments with an original maturity of 90 days or less to be cash and cash equivalents.

7

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 when the Company has the positive intent and ability to hold the securities to maturity. Marketable equity securities and debt securities not classified as held-to-maturity are classified as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and losses, net of tax, reported in other comprehensive loss. 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. Realized gains and losses and declines in value judged to be other-than-temporary on available-for-sale securities are included in investment income. 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.

At June 30, 2017 and December 31, 2016, the Company’s investments were comprised of fixed income investments, and all were deemed available-for-sale. The objectives of the Company’s investment strategy are to provide liquidity and safety of principal while striving to achieve the highest rate of return consistent with these two objectives.  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 support its current operations (including those with a contractual term greater than one year from the date of purchase), are classified as current. All of the Company’s investments are considered current. There were no realized losses for the six months ended June 30, 2017 and 2016. Realized gains were $10,000 and $18,000 for the six months ended June 30, 2017 and 2016, respectively.

We periodically review our investments in unrealized loss positions for other-than-temporary impairments. This evaluation includes, but is not limited to, significant quantitative and qualitative assessments and estimates regarding credit ratings, collateralized support, the length of time and significance of a security’s loss position, our intent not to sell the security, and whether it is more likely than not that we will have to sell the security before recovery of its cost basis. For the six months ended June 30, 2017, no investments were identified with other-than-temporary declines in value.

Available-for-sale securities at June 30, 2017 consisted of the following:

	June 30, 2017

Property and Equipment

Property and equipment are stated at cost and depreciated using the straight-line method over the assets’ estimated useful lives. Maintenance and repairs are expensed when incurred; additions and improvements are capitalized. The estimated useful lives of fixed assets are as follows:

	Estimated
Asset Classification	Useful Life
Laboratory equipment	3 - 5 years
Computer equipment and computer software	3 years
Leasehold improvements	Lesser of the remaining lease term or useful life
Building Improvements	Lesser of the remaining building life or useful life
Furniture and fixtures	3 years
Buildings	30 years

At June 30, 2017, the Company had $9.1 million of assets under construction which consisted of $1.2 million related to leasehold improvements, $2.7 million related to computer equipment and computer software projects and $5.2 million related to machinery and equipment. Depreciation will begin on these assets once they are placed into service. The Company expects to incur an additional $13.2 million to complete the leasehold improvements, $0.3 million to complete the computer equipment and computer software projects, and $10.6 million to complete the machinery and equipment. These projects are expected to be completed in 2017 and 2018. There were no impairment losses for the periods ended June 30, 2017 and December 31, 2016.

Software Capitalization Policy

Software development costs related to internal use software are incurred in three stages of development: the preliminary project stage, the application development stage, and the post-implementation stage. Costs incurred during the preliminary project and post-implementation stages are expensed as incurred. Costs incurred during the application development stage that meet the criteria for capitalization are capitalized and amortized, when the software is ready for its intended use, using the straight-line basis over the estimated useful life of the software.

Patent Costs and Intangible Assets

Patent costs, which have historically consisted of related legal fees, are capitalized as incurred, only if the Company determines that there is some probable future economic benefit to be 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. The Company determined that all patent costs incurred during the six months ended June 30, 2017 should be expensed and not capitalized as the future economic benefit to be derived from the transactions cannot be determined.

Under a technology license and royalty agreement entered into with MDxHealth (“MDx”), dated July 26, 2010 (as subsequently amended, the “License Agreement”), the Company was required to pay MDx milestone-based royalties on sales of products or services covered by the licensed intellectual property. Once the achievement of a milestone occurred or was considered probable, an intangible asset and corresponding liability was reported in other long-term assets and accrued liabilities, respectively. The intangible asset is being amortized over the estimated ten-year useful life of the licensed intellectual property through 2024, and such amortization is reported in cost of sales. The liability was relieved once the milestone was achieved and payment was made. Payment for all remaining milestones under the License Agreement was made as part of the Royalty Buy-Out agreement outlined below.

Effective April 25, 2017, the Company and MDx entered into a Royalty Buy-Out Agreement (“Royalty Buy-Out Agreement”), which terminated the License Agreement.  Pursuant to the Royalty Buy-Out Agreement, the Company paid MDx a one-time fee of $8.0 million in exchange for an assignment of certain patents covered by the License Agreement and the elimination of all ongoing royalties and other payments by the Company to MDx under the License Agreement.  Also included in the Royalty Buy-Out Agreement is a mutual release of liabilities, which includes all

10

amounts previously accrued under the License Agreement.  Concurrently with entering into the Royalty Buy-Out Agreement, the Company entered into a Patent Purchase Agreement (“Patent Purchase Agreement”) with MDx under which it paid MDx an additional $7.0 million in exchange for the assignment of certain other patent rights that were not covered by the License Agreement. The total $15.0 million paid by the Company pursuant to the Royalty Buy-Out Agreement and Patent Purchase Agreement, net of liabilities relieved of $6.6 million, was recorded as an intangible asset and is being amortized over the estimated ten-year useful life of the licensed intellectual property, and such amortization is reported in cost of sales. The $6.6 million of liabilities relieved were related to historical milestones and accrued royalties under the License Agreement.

As of June 30, 2017, an intangible asset of $9.7 million related to historical milestone payments made under the License Agreement and intangible assets acquired as part of the Royalty Buy-Out Agreement and Patent Purchase Agreement is reported in other long-term assets.  As of December 31, 2016, an intangible asset of $1.6 million and a liability of $1.3 million related to historical milestone payments made under the License Agreement, were reported in other long-term assets and accrued liabilities, respectively.  Amortization expense was $0.2 million and $0.1 million for the three months ended June 30, 2017 and June 30, 2016, respectively.  Amortization expense was $0.3 million and $0.1 million for the six months ended June 30, 2017 and June 30, 2016, respectively. 

The estimated remaining useful life of the intangible asset is seven years. The table below represents future amortization expense as of June 30, 2017:

(In thousands)
2017	$	669
2018		1,338
2019		1,338
2020		1,338

Thereafter		3,680
	$	9,701

The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be 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 no impairment losses for the periods ended June 30, 2017 and December 31, 2016.

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 are the same because all outstanding common stock equivalents have been excluded, as they are anti-dilutive due to 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:

	June 30,
(In thousands)	2017	2016
Shares issuable upon exercise of stock options	3,513	5,181
Shares issuable upon the release of restricted stock awards	5,424	5,977
	8,937	11,158

Revenue Recognition

Laboratory Service Revenue.The Company’s laboratory service revenues are generated by performing diagnostic services using our Cologuard test, and the service is completed upon delivery of a test result to an ordering physician. The Company recognizes revenue in accordance with the provisions of ASC 954-605, Health Care Entities - Revenue Recognition.  The Company recognizes revenue on an accrual basis, net of contractual and other adjustments, when amounts that will ultimately be collected can be reasonably estimated. Contractual and other adjustments represent the difference between the list price (the billing rate) and the estimated aggregate reimbursement rate from payers and patients. 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.

The estimates of amounts that will ultimately be collected requires significant judgment by management, and the Company’s judgments will continue to evolve as it gains payment experience with payers and patients.  Historically, in the absence of the ability to reasonably estimate the amount that will ultimately be collected for services, revenue was recognized upon cash receipt. Effective during the first quarter of 2017, the Company determined that it had the ability to reasonably estimate the amount that will ultimately be collected from all payers, including the impact of patient cost-share collections. Accordingly, the Company now recognizes revenue on an accrual basis for all billed claims.

The components of laboratory service revenue, as recognized upon accrual or cash receipt, for the three and six months ended June 30, 2017 and 2016 were as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
(In thousands)	2017		2016		2017		2016
Revenue recognized on an accrual basis	$	57,646	$	19,579	$	101,500	$	33,255
Revenue recognized when cash is received		—		1,606		4,509		2,765
Total	$	57,646	$	21,185	$	106,009	$	36,020

Inventory

Inventory is stated at the lower of cost or market value (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 or has a cost basis in excess of its estimated net realizable value, and records a charge to cost of sales for such inventory, as appropriate. In addition, the Company's products are subject to strict quality control and monitoring which the Company performs throughout the manufacturing process. If certain batches or units of product no longer meet quality specifications or become obsolete due to expiration, the Company records a charge to cost of sales to write down such unmarketable inventory to its estimated net realizable value.

Direct and indirect manufacturing costs incurred during process validation and for other research and development activities, which are not permitted to be sold, have been expensed to research and development. 

Inventory consists of the following:

	June 30,		December 31,
(In thousands)	2017		2016
Raw materials	$	5,009	$	2,408
Semi-finished and finished goods		7,401		4,425
Total inventory	$	12,410	$	6,833

Foreign Currency Translation

For the Company’s international subsidiaries, the local currency is the functional currency. Assets and liabilities of these subsidiaries are translated into United States dollars at the period-end exchange rate or historical rates, as appropriate. Condensed consolidated statements of operations are translated at average exchange rates for the period.

12

The cumulative translation adjustments resulting from changes in exchange rates are included in the condensed consolidated balance sheet as a component of accumulated other comprehensive loss in total Exact Sciences Corporation’s stockholders’ equity. Transaction gains and losses are included in the condensed consolidated statement of operations.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation in the condensed consolidated financial statements and accompanying notes to the condensed consolidated financial statements.

(3) MAYO LICENSE AGREEMENT

Overview

As more fully described in the 2016 Form 10-K, in June 2009 the Company entered into a patent license agreement with MAYO Foundation for Medical Education and Research (“MAYO”). The Company’s license agreement with MAYO was amended and restated in February 2015 and further amended in January 2016. Under the license agreement, MAYO granted the Company an exclusive, worldwide license to certain MAYO patents and patent applications, as well as a non-exclusive, worldwide license with regard to certain MAYO know-how. As expanded by the January 2016 amendment to the license agreement, the scope of the license includes any screening, surveillance or diagnostic tests or tools for use in connection with any type of cancers, pre-cancers, diseases or conditions.

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 products using the licensed MAYO intellectual property, with minimum annual royalty fees of $25,000 each year through 2033, the year the last patent expires. The January 2016 amendment to the MAYO license agreement established various low-single-digit royalty rates on net sales of current and future products and clarified how net sales will be calculated.  As part of the amendment, the royalty rate on the Company’s net sales of Cologuard increased and, if in the future, improvements are made to the Cologuard product, the royalty rate may further increase, but, pursuant to the terms of the January 2016 amendment, would remain a low-single-digit percentage of net sales.

In addition to royalties, the Company is required to pay MAYO cash of $0.2 million, $0.8 million and $2.0 million upon each product reaching $5.0 million, $20.0 million and $50.0 million in cumulative net sales, respectively.

As part of the February 2015 amendment and restatement of the license agreement, the Company agreed to pay MAYO an additional $5.0 million, payable in five annual installments, through 2019. The Company paid MAYO the annual installment of $1.0 million in the first quarter of each of 2015 and 2016. The Company paid MAYO the 2017 installment in December 2016. The Company records the $1.0 million installments to prepaid expenses and other current assets and amortizes each installment over a twelve-month period commencing on February 1 of each year. For the three and six months ended June 30, 2017 and 2016 the Company has recorded $0.3 million and $0.5 million in amortization of the installments, respectively.

In addition, the Company is paying MAYO for research and development efforts. As part of the Company’s research collaboration with MAYO, the Company incurred charges of $1.1 million and $2.2 million for the three and six months ended June 30, 2017, respectively. The Company made payments of $0.5 million and $1.8 million for the three and six months ended June 30, 2017, respectively. The Company recorded an estimated liability of $1.2 million for research and development efforts as of June 30, 2017. The Company incurred charges of $0.8 million and $1.8 million for the three and six months ended June 30, 2016, respectively. The Company made payments of $1.3 million and $2.4 million for the three and six months ended June 30, 2016, respectively. The Company recorded an estimated liability of $0.7 million for research and development efforts as of June 30, 2016.

(4) STOCK-BASED COMPENSATION

Stock-Based Compensation Plans

The Company maintains the 2010 Omnibus Long-Term Incentive Plan (As Amended and Restated Effective April 28, 2015), the 2010 Employee Stock Purchase Plan, the 2015 Inducement Award Plan, the 2016 Inducement Award Plan and the 2000 Stock Option and Incentive Plan (collectively, the “Stock Plans”).

Stock-Based Compensation Expense

The Company records stock-based compensation expense in connection with the amortization of restricted stock and restricted stock unit awards, stock purchase rights granted under the Company’s employee stock purchase plan and stock options granted to employees, non-employee consultants and non-employee directors. The Company recorded $6.1 million and $12.2 million in stock-based compensation expense during the three and six months ended June 30, 2017, respectively. The Company recorded $4.5 million and $10.6 million in stock-based compensation expense during the three and six months ended June 30, 2016, respectively.

Determining Fair Value

Valuation and Recognition – The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. The fair value of each market measure-based award is estimated on the date of grant using a Monte Carlo simulation 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 issued to non-employees, the measurement date is the date when the performance is complete or when the award vests, whichever is the earliest. Accordingly, non-employee awards are re-measured at each reporting period until the final measurement date. The fair value of the award is recognized as stock-based compensation expense over the requisite service period, generally the vesting period. The Black-Scholes and Monte Carlo pricing models utilize 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 used in the Black-Scholes and Monte Carlo valuation models on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent expected term.

Forfeitures – Beginning in 2017, the Company adopted Accounting Standards Update (“ASU”) No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“Update 2016-09”). With the adoption of Update 2016-09, forfeiture estimates are no longer required, and the effects of actual forfeitures are recorded at the time they occur. The impact on the condensed consolidated balance sheet was a cumulative-effect adjustment of $0.4 million, increasing opening accumulated deficit and additional paid-in capital.

Stock Option and Restricted Stock Activity

A summary of stock option activity under the Stock Plans during the six months ended June 30, 2017 is as follows:

				Weighted
		Weighted		Average
		Average		Remaining	Aggregate
		Exercise		Contractual	Intrinsic
Options	Shares	Price		Term (Years)	Value(1)
(Aggregate intrinsic value in thousands)
Outstanding, January 1, 2017	3,505,481	$	7.00	5.5

(1) The aggregate intrinsic value of options outstanding, exercisable and vested and expected to vest is calculated as the difference between the exercise price of the underlying options and the market price of the Company’s common stock for options that had exercise prices that were lower than the $35.37 market price of the Company’s common stock at June 30, 2017.  The total intrinsic value of options exercised during the six months ended June 30, 2017 and 2016 was $2.6 million and $4.6 million, respectively.

15

As of June 30, 2017, there was $49.7 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under all Stock Plans.  Total unrecognized compensation cost will be adjusted for future forfeitures.  The Company expects to recognize that cost over a weighted average period of 2.7 years.

A summary of restricted stock and restricted stock unit activity under the Stock Plans during the six months ended June 30, 2017 is as follows:

(5) FAIR VALUE MEASUREMENTS

The Financial Accounting Standards Board has issued authoritative guidance which requires that 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 the 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.

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.

Fixed-income securities and mutual funds are valued using a third-party pricing agency. The valuation is based on observable inputs including pricing for similar assets and other observable market factors. There has been no material change from period to period.  The estimated fair value of the Company’s long-term debt based on a market approach was approximately $4.6 million and $4.7 million as of June 30, 2017 and December 31, 2016, respectively, and represent Level 2 measurements.  When determining the estimated fair value of the Company’s long-term debt, the Company used market-based risk measurements, such as credit risk.

(6) NEW MARKET TAX CREDIT

As more fully described in the 2016 Form 10-K, 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 one of its Madison, Wisconsin facilities.  This financing arrangement was structured with an unrelated third party financial institution, 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 $2.4 million was recorded in Other Long-Term Liabilities on the consolidated balance sheets. The benefit of this net $2.4 million contribution will be recognized as a decrease in expenses, included in cost of sales, as the Company amortizes the contribution liability over the seven-year compliance period as it is being earned through the Company’s on-going compliance with the conditions of the NMTC program. The Company has recorded $0.1 million and $0.2 million as a decrease of expenses for the three and six months ended June 30, 2017, respectively. At June 30, 2017, the remaining balance of $1.5 million is included in Other Long-Term Liabilities. The Company recorded $0.1 million and $0.2 million as a decrease of expenses for the three and six months ended June 30, 2016, respectively. At June 30, 2016, the remaining balance of $1.9 million was included in Other Long-Term Liabilities. The Company incurred approximately $0.2 million of debt issuance costs related to the above transactions, which are recorded as a direct deduction from the liability. The debt issuance costs are being amortized over the life of the agreements.

(7) LONG-TERM DEBT

During June 2015, the Company entered into a $5.1 million credit agreement with an unrelated third-party financial institution to finance the purchase of a facility located in Madison, Wisconsin. The credit agreement is collateralized by the acquired building.

18

Borrowings under the credit agreement bear interest at 4.15%. The Company made interest-only payments on the outstanding principal balance for the period between July 12, 2015 and September 12, 2015. Beginning on October 12, 2015 and continuing through May 12, 2019, the Company is required to make monthly principal and interest payments of $31,000. The final principal and interest payment due on the maturity date of June 12, 2019 is $4.4 million.

Additionally, the Company has recorded $73,000 in mortgage issuance costs, which are recorded as a direct deduction from the mortgage liability. The issuance costs are being amortized through June 12, 2019. The Company has recorded $4,000 and $9,000 in amortization of mortgage issuance costs for each of the three and six months ended June 30, 2017 and 2016.

(8) 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 if the Company expends $26.3 million in capital investments and establishes and maintains 758 full-time positions in the state of Wisconsin over a seven-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-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-year period.

As of June 30, 2017, the Company has earned $5.9 million of tax credits and has received payment of $1.1 million from the WEDC. The unpaid portion is $4.8 million, of which $1.3 million is reported in prepaid expenses and other current assets and $3.5 million is reported in other long-term assets, reflecting when collection of the refundable tax credits is expected to occur. As of June 30, 2017, the Company also has recorded a $1.3 million liability in other short-term liabilities and a $3.1 million liability in other long-term liabilities, reflecting when the expected benefit of the tax credit amortization will reduce future operating expenses.

During the three and six months ended June 30, 2017, the Company amortized $0.3 million and $0.6 million, respectively, of the tax credits earned as a reduction of operating expenses. During the three and six months ended June 30, 2016, the Company amortized $0.2 million and $0.3 million, respectively, of the tax credits earned as a reduction of operating expenses.

(9) ISSUANCE OF EQUITY

On June 7, 2017, the Company completed an underwritten public offering of 7,000,000 shares of common stock at a price to the public of $35.00 per share. On June 26, 2017, the underwriters partially exercised their over-allotment option in connection with the offering and purchased an additional 450,000 shares of common stock at a price to the public of $35.00 per share. The Company received, in the aggregate, approximately $253.4 million of net proceeds from the offering, after deducting $7.3 million for the underwriting discount and commissions and other stock issuance costs paid by the Company.

19

(10) RELATED PARTY TRANSACTION

In May 2017, the Company entered into a professional services agreement for recruiting and related services with a firm whose principal is a non-employee director. In accordance with the agreement, the Company is expected to make cash payments totaling up to an aggregate of $0.4 million under the agreement during 2017 and 2018. The Company incurred charges of $0.1 million for the three and six months ended June 30, 2017. The Company made payments of $0.1 million for the three and six months ended June 30, 2017.

(11) RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the Financial Accounting Standards Board issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606), (the “New Revenue Standard”) requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Additional disclosures will also be required to enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The New Revenue Standard will replace most existing revenue recognition guidance in GAAP when it becomes effective and permits the use of either the retrospective or modified retrospective method upon adoption. Adoption of the New Revenue Standard is permitted as early as the first quarter of 2017 and is required by the first quarter of 2018. The Company does not plan to early adopt this standard and has not yet selected a transition method. The Company has completed its preliminary evaluation of the potential financial statement impact of the New Revenue Standard on prior and future reporting periods. The Company does not expect material changes to the timing of when the Company recognizes revenue or the method by which the Company measures its single revenue stream, lab service revenue. Further, regarding the contract acquisition cost component of the New Revenue Standard, the Company’s analysis supports use of the practical expedient when recognizing expense related to incremental costs incurred to acquire a contract, as the recovery of such costs is completed in less than one year’s time. Additionally, incremental costs to obtain contracts have been immaterial to date. Accordingly, the Company does not expect any material changes to the timing of when it recognizes expenses related to contract acquisition costs. The Company will continue its evaluation of the New Revenue Standard through the date of adoption.

In February 2016, the Financial Accounting Standards Board issued ASU No. 2016-02, Leases (Topic 842), (“Update 2016-02”) which requires recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP.   The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Early adoption is permitted. The Company is currently evaluating the effects that the adoption of Update 2016-02 will have on the Company’s consolidated financial statements, and anticipate that the new guidance will impact the Company’s consolidated financial statements as it has several leases.

In August 2016, the Financial Accounting Standards Board issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, (“Update 2016-15”). Current GAAP either is unclear or does not include specific guidance on the eight cash flow classification issues included in the amendments in Update 2016-15. The amendments are an improvement to GAAP because they provide guidance for each of the eight issues, thereby reducing the current and potential future diversity in practice.  The amendments in Update 2016-15 are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company has evaluated Update 2016-15 and does not expect the adoption of this guidance to have a material impact on its statements of cash flows.

In October 2016, the Financial Accounting Standards Board issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, (“Update 2016-16”). This amendment improves the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Update 2016-16 is effective for fiscal years and interim periods within those years beginning after December 15, 2017. Early adoption is permitted. The Company does not expect the adoption of Update 2016-16 to have a significant impact on its consolidated financial statements.

20

In October 2016, the Financial Accounting Standards Board issued ASU No. 2016-17, Consolidation (Topic 810): Interests Held through Related Parties That Are Under Common Control, (“Update 2016-17”). The amendments in Update 2016-17 change how a reporting entity that is the single decision maker of a variable interest entity should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that variable interest entity. The amendment is effective for fiscal years and interim periods within those years beginning after December 15, 2016. The Company adopted this guidance during the three months ended March 31, 2017. The impact of adoption did not have an impact on the Company’s consolidated financial statements.

In November 2016, the Financial Accounting Standards Board issued ASU No. 2016-18, Statement of Cash Flows; Restricted Cash, (“Update 2016-18”). Update 2016-18 provides guidance on the classification of restricted cash in the statement of cash flows. The amendments are effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted. The amendments in Update 2016-18 should be adopted on a retrospective basis. The Company does not expect the adoption of this amendment to have a material effect on its consolidated financial statements, as the Company does not have restricted cash.

In January 2017, the Financial Accounting Standards Board issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, (“Update 2017-01”) in an effort to clarify the definition of a business, with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in Update 2017-01 are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In January 2017, the Financial Accounting Standards Board issued ASU No. 2017-03, Accounting Changes and Error Corrections, (“Update 2017-03”) which states that an entity should evaluate ASUs, that have been issued but not yet adopted, to determine the effects of those ASUs on the entity’s financial statements when adopted. If the effect is unknown or cannot be reasonably estimated, then additional qualitative disclosures should be considered, including a description of the effect of the accounting policies that the entity expects to apply, if determined, and a comparison to the entity’s current accounting policies, a description of the status of the entity’s process to implement the new standard and the significant implementation matters yet to be addressed. Transition guidance in certain issued but not yet adopted ASUs was updated to reflect Update 2017-03. Other than enhancements to the qualitative disclosures regarding the future adoption of new ASUs, adoption of Update 2017-03 is not expected to have any impact on the Company’s consolidated financial statements.

In May 2017, the Financial Accounting Standards Board issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting, (“Update 2017-09”). Update 2017-09 provides guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The amendments in Update 2017-09 are effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted. The amendments in Update 2017-09 should be applied prospectively to an award modified on or after the adoption date. The Company is currently evaluating the impact of this amendment on the Company’s consolidated financial statements.

Overview

We are a molecular diagnostics company currently focused on the early detection and prevention of some of the deadliest forms of cancer. We have developed an accurate, non-invasive, patient-friendly screening test called Cologuard, for the early detection of colorectal cancer and pre-cancer, and we are currently working on the development of additional tests for other types of cancer, with the goal of becoming a leader in cancer diagnostics.

22

Our Cologuard Test

Colorectal cancer is the second leading cause of cancer deaths in the United States and the leading cause of cancer deaths in the U.S. among non-smokers. Each year in the U.S. there are approximately:

· 135,000 new cases of colorectal cancer

· 50,000 deaths from colorectal cancer

Colorectal cancer treatment represents a significant, growing healthcare cost. As of 2010, $14 billion was spent annually in the U.S. on colorectal cancer treatment, and the projected annual treatment costs are expected to be $20 billion in 2020. The incidence of colorectal cancer in Medicare patients is expected to rise from 106,000 cases in 2010 to more than 180,000 cases in 2030.

It is widely accepted that colorectal cancer is among the most preventable, yet least prevented cancers. Colorectal cancer can take up to 10-15 years to progress from a pre-cancerous lesion to metastatic cancer and death. Patients who are diagnosed early in the progression of the disease—with pre-cancerous lesions or polyps or early-stage cancer—are more likely to have a complete recovery and to be treated less expensively. Accordingly, the American Cancer Society (“ACS”) recommends that all people age 50 and older undergo regular colorectal cancer screening. Of the more than 80 million people in the U.S. for whom routine colorectal cancer screening is recommended, 38 percent have not been screened according to current guidelines. Poor compliance with screening guidelines has meant that nearly two-thirds of colorectal cancer diagnoses are made in the disease’s late stages. The five-year survival rates for stages 3 and 4 are 67 percent and 12 percent, respectively. We believe the large underserved population of unscreened and inadequately screened patients represents a significant opportunity for a patient-friendly screening test.

Our Cologuard 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. Eleven biomarkers are targeted that have been shown to be strongly associated with colorectal cancer and pre-cancer. Methylation, mutation, and hemoglobin results are combined in the laboratory analysis through a proprietary algorithm to provide a single positive or negative reportable result.

On August 11, 2014 the U.S. Food and Drug Administration (“FDA”) approved Cologuard for use as the first and only sDNA non-invasive colorectal cancer screening test. Our 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%

The competitive advantages of sDNA screening may provide a significant market opportunity. If the test were used by 30-percent of the eligible screening population at a three-year screening interval rate, we estimate the potential U.S. market for sDNA screening would be more than $4 billion, annually.

Our-Cologuard Commercialization Strategy

Our commercialization strategy includes three main elements focusing on physicians, patients, and payers.

Physicians and Patients

Our sales team actively engages with physicians and their staffs to emphasize the need for colorectal cancer screening, educate them on the value of Cologuard, and enroll them in our physician ordering system to enable them to prescribe the test. We focus on specific physicians based on Cologuard order history and on physician groups and larger regional and national health systems.

23

Securing inclusion in guidelines and quality measures is a key part of our physician engagement strategy since many physicians rely on such guidelines and quality measures when making screening recommendations. In June 2016, the US Preventive Services Task Force (“USPSTF”) issued an updated recommendation statement for colorectal cancer screening and gave an “A” grade to colorectal cancer screening starting at age 50 and continuing until age 75. The statement specifies seven screening methods, including FIT-DNA (which is Cologuard).

Many professional colorectal cancer screening guidelines in the U.S., including those of the ACS, the American College of Gastroenterology (“ACG”), the American Gastroenterological Association (“AGA”) and the National Comprehensive Cancer Network (“NCCN”), recommend regular screening by a variety of methods.  Since 2008, joint colorectal cancer screening guidelines endorsed by the ACS have included sDNA screening technology as a screening option for the detection of colorectal cancer in average risk, asymptomatic individuals age 50 and older.  In October 2014, the ACS updated its colorectal cancer screening guidelines to specifically include Cologuard as a recommended sDNA screening test.  In June 2016, the NCCN updated its Colorectal Cancer Screening Guidelines to add sDNA screening, at a once-every-three-years interval, to its list of recommended screening tests.

In October 2016, the National Committee for Quality Assurance (“NCQA”) included Cologuard testing on a three-year interval in the 2017 Healthcare Effectiveness Data and Information Set (“HEDIS”) measures. More than 90 percent of America’s health plans measure quality based on HEDIS.  In April 2017, the Centers for Medicare & Medicaid Services (“CMS”) included Cologuard in its updated 2018 Medicare Advantage Star Ratings program. Medicare Advantage plans are eligible to receive quality credit under the Star Ratings program for Cologuard tests completed in 2014, 2015, 2016 and beyond.

A critical part of the value proposition of Cologuard is our compliance program, which involves active engagement with patients and physicians. This customer-service-oriented activity is focused on helping patients to complete Cologuard tests that have been ordered for them by their physicians and supporting physicians in their efforts to have their patients screened.

After the launch of Cologuard, we initiated a significant public relations effort to engage patients in the United States. We have conducted targeted direct-to-patient advertising campaigns through social media, print and other channels. In 2016 we began a national television advertising campaign. To date, we have focused our efforts on cable television most commonly viewed by our target patient demographic. In 2017, we plan to continue our targeted direct-to-patient advertising initiatives and during the second quarter of 2017 we launched new content for our television advertising campaign, which continues to focus on the ease of use of Cologuard.

Payers

The cornerstone of our payer-engagement strategy was securing coverage from CMS. Medicare covers 47% of patients in the screening population for Cologuard. On October 9, 2014, CMS issued a National Coverage Determination (“NCD”) for Cologuard following a parallel review process with FDA.  Cologuard was the first screening test approved by FDA and covered by CMS through that process. As outlined in the NCD, Medicare Part B covers Cologuard once every three years for beneficiaries who meet all of the following criteria:

· age 50 to 85 years,

· asymptomatic (no signs or symptoms of colorectal disease including but not limited to lower gastrointestinal pain, blood in stool, positive guaiac fecal occult blood test or fecal immunochemical test), and

· at average risk for developing colorectal cancer (e.g., no personal history of adenomatous polyps, colorectal cancer, or inflammatory bowel disease, including Crohn’s Disease and ulcerative colitis; no family history of colorectal cancers or adenomatous polyps, familial adenomatous polyposis, or hereditary non-polyposis colorectal cancer).

In the 2017 Clinical Laboratory Fee Schedule, CMS established reimbursement for Cologuard at $512.43. Payments from CMS are currently subject to sequestration. Under the Protecting Access to Medicare Act of 2014 (“PAMA”), we anticipate that, effective January 1, 2018, the CMS reimbursement rate for Cologuard will be calculated based on the volume-weighted median of private payer rates for Cologuard. The initial data collection period for that

24

purpose was the period between January 1, 2016 and June 30, 2016. The CMS reimbursement rate will subsequently be reset every three years, or every year if the Company applies for, and is granted, Advanced Diagnostic Laboratory Test (“ADLT”) status for Cologuard, based on the volume-weighted median of private payer rates experienced in the applicable six-month data collection period. We submitted data for the initial collection period in March 2017, and our data submission will be subject to review by CMS prior to the finalization of the new reimbursement rate for Cologuard. We currently do not anticipate applying to CMS for ADLT status for Cologuard. Therefore, we anticipate that Cologuard will be treated as a Clinical Diagnostic Laboratory Test (“CDLT”) and that its pricing under PAMA will be established for three-year periods.

In addition to Medicare reimbursement, we believe it is necessary to secure favorable coverage and in-network reimbursement agreements from commercial payers for Cologuard to achieve its full commercial potential. Some commercial payers have issued positive coverage decisions for Cologuard and others have agreed to cover Cologuard as an in-network service. We believe that commercial payers’ reimbursement of Cologuard will depend on a number of factors, including payers’ determination that it is: sensitive and specific for colorectal cancer; not experimental or investigational; approved or recommended by major organizations’ guidelines; reliable, safe and effective; medically necessary; appropriate for the specific patient; and cost-effective. Also, some payers may require that they give prior authorization for a Cologuard test before they are willing to pay for it and other payers may perform post-payment reviews or audits, which could lead to payment recoupments. Prior authorizations and post-payment review or audits may require that we, patients, or physicians provide the payer with extensive medical records and other information.

Coverage of Cologuard may also depend, in whole or in part, on whether payers determine, or courts and/or regulatory authorities determine, coverage is required under applicable federal or state laws mandating coverage of certain colorectal cancer screening services. For example, Section 2713 of the Patient Protection and Affordable Care Act (“ACA”) mandates that certain health insurers cover evidence-based items or services that have in effect a rating of “A” or “B” in the current recommendations of USPSTF without imposing any patient cost-sharing (“ACA Mandate”). Similarly, federal regulations require that Medicare Advantage plans cover “A” or “B” rated preventive services without patient cost-sharing. Following the June 2016 update to the USPSTF colorectal cancer screening recommendation statement, CMS issued an updated Evidence of Coverage notice for Medicare Advantage plans that affirms such plans must include coverage of Cologuard every three years without patient cost-sharing. While we believe the ACA Mandate will require certain health insurers to cover Cologuard without patient cost-sharing (following an initial phase-in period between one and two years from the date of the updated USPSTF recommendation statement depending on the date a given plan year commences), it is possible that certain health insurers will disagree, in which case courts and/or governmental agencies may need to resolve the matter. It is also possible that the ACA Mandate will be repealed or significantly modified in the future.

Similarly, we believe the laws of approximately 30 states currently mandate coverage of Cologuard by certain health insurance plans. While some insurers have agreed with our interpretation with regard to certain states, other insurers have disagreed with regard to other states. In some cases, we have filed lawsuits in an effort to enforce state laws we believe require coverage of Cologuard, and we may file additional suits in the future. We may or may not be successful in any such lawsuit.

We are pursuing a variety of strategies to increase commercial payer coverage for Cologuard, including providing cost effectiveness data to payers to make the case for Cologuard reimbursement. We are focusing our efforts on large national and regional insurers, insurers in states with coverage mandates for colorectal cancer screening, and health plans that have affiliated health systems.

We believe quality metrics may influence payers’ coverage decisions, as well as physicians’ cancer screening procedures. Some government and private payers are adopting pay-for-performance programs that differentiate payments for healthcare services based on the achievement of documented quality metrics, cost efficiencies or patient outcomes. Payers may look to quality measures such as the HEDIS and CMS Star Ratings measures to assess quality of care. We believe inclusion in the HEDIS measures and Star Ratings measures may have a positive impact on payers’ willingness to reimburse Cologuard, as well as on physicians’ willingness to prescribe the test.  

25

Our Clinical Lab Facility

As part of our commercialization strategy, we established a state-of-the-art, highly automated lab facility that is certified pursuant to federal Clinical Laboratory Improvement Amendments (“CLIA”) requirements to process Cologuard tests and provide patient results. Our commercial lab operation is housed in a 50,000 square foot facility in Madison, Wisconsin. At our lab, we currently have the capacity to process approximately one million tests per year. We are currently exploring opportunities to increase our capacity to two million or more tests per year at our existing lab facility, which includes expanding our current lab facility. We are also evaluating options for a second lab facility to increase our total capacity to more than four million tests per year.

Product Pipeline

We also are developing a pipeline of potential future products and services. We are continuing to collaborate with MAYO Foundation for Medical Education and Research (“MAYO”), our development partner for Cologuard, on developing new tests, with the goal of becoming a leader in cancer diagnostics. We believe Cologuard’s technological platform provides a strong foundation for the development of additional cancer diagnostic tests. Through our collaboration with MAYO, we have identified proprietary methylation markers for several major cancers. We have successfully performed validation studies on tissue samples for seven major cancers, including lung cancer, and on blood samples for four major cancers.

The ACS estimates that lung cancer will be diagnosed in 223,000 Americans and cause 156,000 deaths in the United States in 2017. Currently, more than half of lung cancer cases are diagnosed at an advanced stage, after symptoms appear, when the five-year survival rate is in the low single digits. We are currently developing a blood-based biomarker test to aid in the early detection of lung cancer in individuals with lung nodules discovered through a computerized tomography (“CT”) or other scan. Such a test may help reduce the number of unnecessary biopsies and other follow-up procedures, and thereby reduce costs and improve health outcomes. We recently completed a multi-round study of nearly 400 patients, which demonstrated high accuracy for detecting lung cancer at all stages.

We also continue to explore opportunities for improving Cologuard, including improvements that could lower our cost of sales.

How We Recognize Revenue

For tests performed where we have an agreed-upon reimbursement rate or where we can estimate the amount that we will ultimately collect at the time delivery is complete, we recognize the related revenue on an accrual basis upon delivery of a test result to an ordering physician. Accrual rates are based on the established billing rates less contractual and other adjustments, which yields the amount that we expect to ultimately collect. We determine the amount we expect to ultimately collect on a per-payer or per-agreement basis. The expected amount is typically lower than, if applicable, the agreed-upon reimbursement amount due to several factors, such as the amount of any patient co-payments, the existence of secondary payers and claim denials. 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 recognize revenue from claims on an accrual basis and later determine the judgments underlying estimated collections change, our financial results could be negatively impacted in future quarters.  Historically, a portion of our revenue was recognized upon cash receipt when we were unable to reasonably estimate the amount that would ultimately be collected from a payer. Effective during the first quarter of 2017, we determined that we had the ability to reasonably estimate the amount that will ultimately be collected from all payers, including the impact of patient cost-share collections. Accordingly, we now recognize revenue on an accrual basis for all billed claims.

Our average reimbursement per test, as further defined below, was approximately $423 and $386 through June 30, 2017 and 2016, respectively. This cumulative average Cologuard reimbursement rate will change over time due to a number of factors, including medical coverage decisions by payers, changes in the payer mix, the effects of contracts signed with payers, changes in allowed amounts by payers, our ability to successfully win appeals for payment, settlements reached with payers regarding previously denied claims and our ability to collect cash payments from payers and individual patients. Historical average reimbursement is not necessarily indicative of future average reimbursement.

26

We calculate the average Cologuard reimbursement per test on a trailing twelve-month basis for all tests that are at least six months old, since it can take that long, or in some cases longer, to collect from some payers and patients. Thus, the average reimbursement per test represents the total cash collected through June 30, 2017 and 2016 for all tests performed during the relevant periods divided by the number of tests performed during those same periods.

The components of our revenue, as recognized upon accrual or cash receipt, were as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
(In thousands)	2017		2016		2017		2016
Revenue recognized on an accrual basis	$	57,646	$	19,579	$	101,500	$	33,255
Revenue recognized when cash is received		—		1,606		4,509		2,765
Total	$	57,646	$	21,185	$	106,009	$	36,020

Of the revenue recognized in the six months ended June 30, 2017, approximately $4.3 million relates to the one-time impact of certain payers meeting the Company’s revenue recognition criteria for accrual-basis revenue recognition beginning with the period ended March 31, 2017. Approximately $1.0 million of this one-time impact relates to tests completed in the prior year and for which our accrual revenue recognition criteria were not met until 2017.

2017 Priorities

Our top priorities for 2017 are to (1) grow revenue for Cologuard, which includes leveraging Cologuard’s growth towards becoming a standard of care, (2) improve the customer experience and continue to deliver world class service to patients and providers, and (3) expand our product portfolio by developing additional cancer diagnostic tests as further outlined in the product pipeline section above.

Results of Operations

We have generated significant losses since inception and, as of June 30, 2017, we had an accumulated deficit of approximately $812.0 million. We expect to continue to incur losses for the near future, and it is possible we may never achieve profitability.

Laboratory service revenue. Our laboratory service revenue is generated by performing diagnostic services using our Cologuard test. For the three months ended June 30, 2017 and 2016, we completed approximately 135,000 and 54,000 Cologuard tests, respectively, and generated laboratory service revenue of $57.6 million and $21.2 million, respectively. For the six months ended June 30, 2017 and 2016, the Company completed approximately 235,000 and 94,000 Cologuard tests, respectively, and generated laboratory service revenue of $106.0 million and $36.0 million, respectively. The increase in revenue was primarily due to an increase in completed Cologuard tests and an increase in average revenue recognized per test during the current period.

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 test collection kits, royalties and the cost of laboratory services to process tests and provide results to physicians. We incur expense for tests in the period in which the activities occur, therefore, gross margin as a percentage of laboratory service revenue may vary due to costs being incurred in one period that relate to revenues recognized in a later period.

We expect that gross margin for our laboratory services will continue to fluctuate and be affected by Cologuard test volume, operating efficiencies, patient compliance rates, payer mix, the levels of reimbursement, and payment patterns of payers and patients.

27

Cost of Sales. Cost of sales increased to $18.0 million for the three months ended June 30, 2017 compared to $10.1 million for the three months ended June 30, 2016. Cost of sales increased to $35.0 million for the six months ended June 30, 2017 compared to $19.2 million for the six months ended June 30, 2016. The increase in cost of sales is primarily due to the increase in completed Cologuard tests. The Company completed approximately 135,000 and 54,000 Cologuard tests for the three months ended June 30, 2017 and 2016, respectively. The Company completed approximately 235,000 and 94,000 Cologuard tests for the six months ended June 30, 2017 and 2016, respectively.

Research and development expenses. Research and development expenses increased to $9.7 million for the three months ended June 30, 2017 compared to $8.6 million for the three months ended June 30, 2016. Research and development expenses decreased to $17.7 million for the six months ended June 30, 2017 compared to $18.8 million for the six months ended June 30, 2016. The increase in research and development expenses for the three months ended June 30, 2017 compared to the three months ended June 30, 2016 was primarily due to an increase in personnel costs due to an increased headcount and an increase in direct research and development expenses for our pipeline. The decrease in research and development expenses for the six months ended June 30, 2017 compared to the six months ended June 30, 2016 was due to a reduction in direct research and development expenses as a result of one-time validation charges that were incurred in 2016.

General and administrative expenses.  General and administrative expenses increased to $24.6 million for the three months ended June 30, 2017 compared to $17.3 million for the three months ended June 30, 2016. General and administrative expenses increased to $44.7 million for the six months ended June 30, 2017 compared to $35.1 million for the six months ended June 30, 2016. The increase in general and administrative expenses was primarily a result of increased legal and professional fees and personnel costs to support the overall growth of the Company.

Sales and marketing expenses. Sales and marketing expenses increased to $36.7 million for the three months ended June 30, 2017 compared to $30.3 million for the three months ended June 30, 2016. Sales and marketing expenses increased to $75.5 million for the six months ended June 30, 2017 compared to $56.0 million for the six months ended June 30, 2016. The increase in sales and marketing expenses was a result of hiring additional sales and marketing personnel and increasing our advertising and patient marketing efforts as part of the ongoing commercialization of our Cologuard test.

Investment income.  Investment income increased to $0.7 million for the three months ended June 30, 2017 compared to $0.4 million for the three months ended June 30, 2016.  Investment income increased to $1.3 million for the six months ended June 30, 2017 compared to $0.9 million for the six months ended June 30, 2016. The increase in investment income was due to an increase in the average cash and marketable securities balance and an increase in the average rate of return on investments for the three and six months ended June 30, 2017 when compared to the same periods in 2016.

29

Interest income and expense. Net interest expense of $54,000 was realized for the three months ended June 30, 2017 compared to net interest expense of $53,000 for the three months ended June 30, 2016. Net interest expense of $0.1 million was realized for each of the six months ended June 30, 2017 and June 30, 2016. Interest expense is related to the mortgage on one of our facilities in Madison, WI which was entered into in June 2015.

Liquidity and Capital Resources

We have financed our operations since inception primarily through public offerings of our common stock and through revenue generated by the sale of Cologuard. As of June 30, 2017, we had approximately $180.4 million in cash and cash equivalents and approximately $303.9 million in marketable securities.

All 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 $65.5 million for the six months ended June 30, 2017 as compared to $78.0 million for the six months ended June 30, 2016. The principal use of cash in operating activities for the six months ended June 30, 2017 was to fund our net loss. Our net loss decreased from the six months ended June 30, 2016 primarily due to increased sales of Cologuard.

Net cash used in investing activities was $58.9 million for the six months ended June 30, 2017 as compared to net cash provided by investing activities of $84.5 million for the six months ended June 30, 2016.  The increase in cash used in investing activities for the six months ended June 30, 2017 compared to the same period in 2016 was primarily the result of the timing of purchases and maturities of marketable securities. Excluding the impact of purchases and maturities of marketable securities, net cash used in investing activities consisted of purchases of property and equipment of $8.6 million and purchases of intangible assets of $8.4 million for the six months ended June 30, 2017 compared to purchases to property and equipment of $6.4 million and no purchase of intangible assets for the six months ended June 30, 2016. The intangible asset purchase during the six months ended June 30, 2017 was the result of the royalty buy-out and patent purchase from MDx Health in April 2017. The property and equipment purchases during the six months ended June 30, 2017 were primarily the result of increased laboratory equipment purchases, computer equipment and computer software purchases, and assets under construction in order to continue to scale-up our operations.

Net cash provided by financing activities was $255.8 million for the six months ended June 30, 2017, as compared to $1.5 million for the six months ended June 30, 2016. The increase in cash provided by financing activities for the six months ended June 30, 2017 compared to the same period in 2016 was primarily the result of proceeds from our issuance of common stock in an underwritten public offering in June 2017.

We expect that cash and cash equivalents and marketable securities on hand at June 30, 2017 will be sufficient to fund our current operations for at least the next twelve months, based on current operating plans. However, we may need to raise additional capital to fully fund our current strategic plan, which includes successfully commercializing Cologuard and developing a pipeline of future products. 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 additional funds, we cannot assure that our business will ever generate sufficient cash flow from operations to become profitable.

Critical Accounting Policies and 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 States (“GAAP”). The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, tax positions and stock-based compensation. We base our estimates on historical experience and on various other factors

30

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.

While our significant accounting policies are more fully described in Note 2 of our financial statements included in our 2016 Form 10-K, we believe that the following accounting policies and judgments are most critical to aid in fully understanding and evaluating our reported financial results.

Revenue Recognition

Laboratory service revenue. Our laboratory service revenues are generated by performing diagnostic services using our Cologuard test, and the service is completed upon delivery of a test result to an ordering physician. We recognize revenue in accordance with the provisions of ASC 954-605, Health Care Entities - Revenue Recognition.  We recognize revenue on an accrual basis, net of contractual and other adjustments, when amounts that will ultimately be collected can be reasonably estimated. Contractual and other adjustments represent the difference between the list price (the billing rate) and the estimated aggregate reimbursement rate from payers and patients. 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.

The estimates of amounts that will ultimately be collected requires significant judgment by management, and our judgements will continue to evolve as we gain payment experience with payers and patients.  Historically, in the absence of the ability to reasonably estimate the amount that will ultimately be collected for our services, revenue was recognized upon cash receipt. Effective during the first quarter of 2017, we determined that we had the ability to reasonably estimate the amount that will ultimately be collected from all payers, including the impact of patient cost-share collections. Accordingly, we now recognize revenue on an accrual basis for all billed claims.

Inventory.Inventory is stated at the lower of cost or market value (net realizable value). We determine the cost of inventory using the first-in, first out method (“FIFO”). We estimate the recoverability of inventory by reference to internal estimates of future demands and product life cycles, including expiration. We periodically analyze our inventory levels to identify inventory that may expire prior to expected sale or has a cost basis in excess of its estimated net realizable value, and record a charge to cost of sales for such inventory as appropriate. In addition, our products are subject to strict quality control and monitoring which we perform throughout the manufacturing process. If certain batches or units of product no longer meet quality specifications or become obsolete due to expiration, we record a charge to cost of sales to write down such unmarketable inventory to its estimated net realizable value.

Direct and indirect manufacturing costs incurred during process validation and for other research and development activities, which are not permitted to be sold, have been expensed to research and development. 

Stock-Based Compensation.  In accordance with GAAP, all stock-based payments, including grants of employee stock options, restricted stock and restricted stock units, market measure-based awards and shares purchased under an employee stock purchase plan (“ESPP”) (if certain parameters are not met), are recognized in the financial statements based on their fair values. The grant date fair value of market measure-based share-based compensation plans are calculated using a Monte Carlo simulation pricing model. The following assumptions are used in determining fair value for stock options, restricted stock and ESPP shares:

· Valuation and Recognition — The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model. The fair value of each market measure-based award is estimated on the date of grant using a Monte Carlo simulation 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 issued to non-employees, the measurement date is the date when the performance is complete or when the award vests, whichever is the earliest. Accordingly, non-employee awards are re-measured at each reporting period until the final measurement date. The fair value of the award is recognized as stock-based compensation expense over the requisite service period, generally the vesting period. The Black-Scholes and Monte Carlo pricing models utilize the following assumptions:

31

· Expected Term - Expected term is based on our historical life data and is determined using the average of the vesting period and the contractual life of the stock options granted. Expected life of a market measure-based award is based on the applicable performance period.

· Expected Volatility - Expected volatility is based on our historical stock volatility data over the expected term of the awards.

· Risk-Free Interest Rate – We base the risk-free interest rate used in the Black-Scholes and Monte Carlo valuation models on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent expected term.

· Forfeitures – Beginning in 2017, we adopted Accounting Standards Update (“ASU”) No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“Update 2016-09”). With the adoption of Update 2016-09, forfeiture estimates are no longer required, and the effects of actual forfeitures are recorded at the time they occur. The impact on the condensed consolidated balance sheet was a cumulative-effect adjustment of $0.4 million, increasing opening accumulated deficit and additional paid-in capital.

The fair value of each award is estimated on the date of grant based on the assumptions noted above and as further described in Note 4 to our condensed consolidated financial statements.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606), (the “New Revenue Standard”) requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Additional disclosures will also be required to enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The New Revenue Standard will replace most existing revenue recognition guidance in GAAP when it becomes effective and permits the use of either the retrospective or modified retrospective method upon adoption. Adoption of the New Revenue Standard is permitted as early as the first quarter of 2017 and is required by the first quarter of 2018. We do not plan to early adopt this standard and we have not yet selected a transition method. We have completed our preliminary evaluation of the potential financial statement impact of the New Revenue Standard on prior and future reporting periods. We do not expect material changes to the timing of when we recognize revenue or the method by which we measure our single revenue stream, lab service revenue. Further, regarding the contract acquisition cost component of the New Revenue Standard, our preliminary analysis supports the use of the practical expedient when recognizing expense related to incremental costs incurred to acquire a contract, as the recovery of such costs is completed in less than one year’s time. Additionally, incremental costs to obtain contracts have been immaterial to date. Accordingly, we do not expect any material changes to the timing of when we recognize expenses related to contract acquisition costs. We will continue our evaluation of the New Revenue Standard through the date of adoption.

In February 2016, the Financial Accounting Standards Board issued ASU No. 2016-02, Leases (Topic 842), (“Update 2016-02”) which requires recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP.   The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Early adoption is permitted. We are currently evaluating the effects that the adoption of Update 2016-02 will have on our consolidated financial statements, and anticipate that the new guidance will impact our consolidated financial statements, as we have several leases.

In August 2016, the Financial Accounting Standards Board issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, (“Update 2016-15”). Current GAAP either is unclear or does not include specific guidance on the eight cash flow classification issues included in the amendments in Update 2016-15. The amendments are an improvement to GAAP because they provide guidance for each of the eight issues, thereby reducing the current and potential future diversity in practice.  The amendments in Update 2016-15 are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. We have

32

evaluated Update 2016-15 and we do not expect the adoption of this guidance to have a material impact on our statements of cash flows.

In October 2016, the Financial Accounting Standards Board issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, (“Update 2016-16”). This amendment improves the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Update 2016-16 is effective for fiscal years and interim periods within those years beginning after December 15, 2017. Early adoption is permitted. We do not anticipate that the adoption of Update 2016-16 will have a significant impact on our consolidated financial statements.

In October 2016, the Financial Accounting Standards Board issued ASU No. 2016-17, Consolidation (Topic 810): Interest Held through Related Parties That Are Under Common Control, (Update 2016-17”). The amendments in Update 2016-17 change how a reporting entity that is the single decision maker of a variable interest entity should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that variable interest entity. The amendment is effective for fiscal years and interim periods within those years beginning after December 15, 2016. The adoption of Update 2016-17 did not have an impact on our consolidated financial statements.

In November 2016, the Financial Accounting Standards Board issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, (“Update 2016-18”). Update 2016-18 provides guidance on the classification of restricted cash in the statement of cash flows. The amendments are effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted. The amendments in the Update 2016-18 should be adopted on a retrospective basis. We do not expect that adoption of this amendment to have a material effect on our consolidated financial statements, as we do not have restricted cash.

In January 2017, the Financial Accounting Standards Board issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, (Update 2017-01) in an effort to clarify the definition of a business, with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments of Update 2017-01 are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

In January 2017, the Financial Accounting Standards Board issued ASU No. 2017-03, Accounting Changes and Error Corrections, (“Update 2017-03”) which states that an entity should evaluate ASUs, that have been issued but not yet adopted, to determine the effects of those ASUs on the entity’s financial statements when adopted. If the effect is unknown or cannot be reasonably estimated, then additional qualitative disclosures should be considered, including a description of the effect of the accounting policies that the entity expects to apply, if determined, and a comparison to the entity’s current accounting policies, a description of the status of the entity’s process to implement the new standard and the significant implementation matters yet to be addressed. Transition guidance in certain issued but not yet adopted ASUs was updated to reflect Update 2017-03. Other than enhancements to the qualitative disclosures regarding the future adoption of new ASUs, adoption of Update 2017-03 is not expected to have any impact on our consolidated financial statements.

In May 2017, the Financial Accounting Standards Board issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting, (“Update 2017-09”). Update 2017-09 provides guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The amendments in Update 2017-09 are effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted. The amendments in Update 2017-09 should be applied prospectively to an award modified on or after the adoption date. We are currently evaluating the impact of this amendment on our consolidated financial statements.

Off-Balance Sheet Arrangements

As of June 30, 2017, we had no off-balance sheet arrangements.

Item 3. Quantitative and Qualitative Disclosures About Market 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. government and its agencies and in investment-grade, highly liquid investments consisting of commercial paper, bank certificates of deposit, asset backed securities and corporate bonds, which, as of June 30, 2017 were classified as available-for-sale. We place our cash equivalents 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.

Item 4. Controls and 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 June 30, 2017, 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.

During the fiscal quarter covered by this report, there have been no significant changes in internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II - Other Information

Item 1.  Legal Proceedings

We are not currently a party to any pending legal proceedings that we believe will have a material adverse effect on our business, financial condition or results of operations. We may, however, be subject to various claims and legal actions arising in the ordinary course of business from time to time.

Item 1A. Risk 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” on the 2016 Form 10-K.  There have been no material changes to the risk factors described in the 2016 Form 10-K.

ORGANIZATION AND BASIS OF PRESENTATION

ORGANIZATION AND BASIS OF PRESENTATION

(1) ORGANIZATION AND BASIS OF PRESENTATION

Organization

Exact Sciences Corporation (“Exact” or the “Company”) was incorporated in February 1995. Exact is a molecular diagnostics company currently focused on the early detection and prevention of some of the deadliest forms of cancer. The Company has developed an accurate, non-invasive, patient-friendly screening test called Cologuard® for the early detection of colorectal cancer and pre-cancer, and is currently working on the development of tests for other types of cancer.

Basis of Presentation

The accompanying condensed consolidated financial statements, which include the accounts of Exact Sciences Corporation and those of its wholly owned subsidiaries, Exact Sciences Laboratories, LLC, Exact Sciences Finance Corporation, Exact Sciences Europe LTD, Beijing Exact Sciences Medical Technology Company Limited, 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, 2016 included in the Company’s Annual Report on Form 10-K (the “2016 Form 10-K”). 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, all adjustments (consisting only of adjustments of a normal and recurring nature) considered necessary for a fair presentation of the results of operations have been included. 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 2016 Form 10-K.  Management has evaluated subsequent events for disclosure or recognition in the accompanying financial statements up to the filing of this report.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of the Company’s wholly owned subsidiaries, Exact Sciences Laboratories, LLC, Exact Sciences Finance Corporation, Exact Sciences Europe LTD, Beijing Exact Sciences Medical Technology Company Limited, and variable interest entities. All significant intercompany transactions and balances have been eliminated in consolidation.

References to “Exact”, “we”, “us”, “our”, or the “Company” refer to Exact Sciences Corporation and its wholly owned subsidiaries.

Use of Estimates

The preparation of 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.  Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers cash on hand, demand deposits in bank, money market funds, and all highly liquid investments with an original maturity of 90 days or less to be cash and cash equivalents.

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 when the Company has the positive intent and ability to hold the securities to maturity. Marketable equity securities and debt securities not classified as held-to-maturity are classified as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and losses, net of tax, reported in other comprehensive loss. 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. Realized gains and losses and declines in value judged to be other-than-temporary on available-for-sale securities are included in investment income. 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.

At June 30, 2017 and December 31, 2016, the Company’s investments were comprised of fixed income investments, and all were deemed available-for-sale. The objectives of the Company’s investment strategy are to provide liquidity and safety of principal while striving to achieve the highest rate of return consistent with these two objectives.  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 support its current operations (including those with a contractual term greater than one year from the date of purchase), are classified as current. All of the Company’s investments are considered current. There were no realized losses for the six months ended June 30, 2017 and 2016. Realized gains were $10,000 and $18,000 for the six months ended June 30, 2017 and 2016, respectively.

We periodically review our investments in unrealized loss positions for other-than-temporary impairments. This evaluation includes, but is not limited to, significant quantitative and qualitative assessments and estimates regarding credit ratings, collateralized support, the length of time and significance of a security’s loss position, our intent not to sell the security, and whether it is more likely than not that we will have to sell the security before recovery of its cost basis. For the six months ended June 30, 2017, no investments were identified with other-than-temporary declines in value.

Total reclassifications		$	(4)	$	39

Property and Equipment

Property and equipment are stated at cost and depreciated using the straight-line method over the assets’ estimated useful lives. Maintenance and repairs are expensed when incurred; additions and improvements are capitalized. The estimated useful lives of fixed assets are as follows:

	Estimated
Asset Classification	Useful Life
Laboratory equipment	3 - 5 years
Computer equipment and computer software	3 years
Leasehold improvements	Lesser of the remaining lease term or useful life
Building Improvements	Lesser of the remaining building life or useful life
Furniture and fixtures	3 years
Buildings	30 years

At June 30, 2017, the Company had $9.1 million of assets under construction which consisted of $1.2 million related to leasehold improvements, $2.7 million related to computer equipment and computer software projects and $5.2 million related to machinery and equipment. Depreciation will begin on these assets once they are placed into service. The Company expects to incur an additional $13.2 million to complete the leasehold improvements, $0.3 million to complete the computer equipment and computer software projects, and $10.6 million to complete the machinery and equipment. These projects are expected to be completed in 2017 and 2018. There were no impairment losses for the periods ended June 30, 2017 and December 31, 2016.

Software Capitalization Policy

Software development costs related to internal use software are incurred in three stages of development: the preliminary project stage, the application development stage, and the post-implementation stage. Costs incurred during the preliminary project and post-implementation stages are expensed as incurred. Costs incurred during the application development stage that meet the criteria for capitalization are capitalized and amortized, when the software is ready for its intended use, using the straight-line basis over the estimated useful life of the software.

Patent Costs and Intangible Assets

Patent costs, which have historically consisted of related legal fees, are capitalized as incurred, only if the Company determines that there is some probable future economic benefit to be 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. The Company determined that all patent costs incurred during the six months ended June 30, 2017 should be expensed and not capitalized as the future economic benefit to be derived from the transactions cannot be determined.

Under a technology license and royalty agreement entered into with MDxHealth (“MDx”), dated July 26, 2010 (as subsequently amended, the “License Agreement”), the Company was required to pay MDx milestone-based royalties on sales of products or services covered by the licensed intellectual property. Once the achievement of a milestone occurred or was considered probable, an intangible asset and corresponding liability was reported in other long-term assets and accrued liabilities, respectively. The intangible asset is being amortized over the estimated ten-year useful life of the licensed intellectual property through 2024, and such amortization is reported in cost of sales. The liability was relieved once the milestone was achieved and payment was made. Payment for all remaining milestones under the License Agreement was made as part of the Royalty Buy-Out agreement outlined below.

Effective April 25, 2017, the Company and MDx entered into a Royalty Buy-Out Agreement (“Royalty Buy-Out Agreement”), which terminated the License Agreement.  Pursuant to the Royalty Buy-Out Agreement, the Company paid MDx a one-time fee of $8.0 million in exchange for an assignment of certain patents covered by the License Agreement and the elimination of all ongoing royalties and other payments by the Company to MDx under the License Agreement.  Also included in the Royalty Buy-Out Agreement is a mutual release of liabilities, which includes all amounts previously accrued under the License Agreement.  Concurrently with entering into the Royalty Buy-Out Agreement, the Company entered into a Patent Purchase Agreement (“Patent Purchase Agreement”) with MDx under which it paid MDx an additional $7.0 million in exchange for the assignment of certain other patent rights that were not covered by the License Agreement. The total $15.0 million paid by the Company pursuant to the Royalty Buy-Out Agreement and Patent Purchase Agreement, net of liabilities relieved of $6.6 million, was recorded as an intangible asset and is being amortized over the estimated ten-year useful life of the licensed intellectual property, and such amortization is reported in cost of sales. The $6.6 million of liabilities relieved were related to historical milestones and accrued royalties under the License Agreement.

As of June 30, 2017, an intangible asset of $9.7 million related to historical milestone payments made under the License Agreement and intangible assets acquired as part of the Royalty Buy-Out Agreement and Patent Purchase Agreement is reported in other long-term assets.  As of December 31, 2016, an intangible asset of $1.6 million and a liability of $1.3 million related to historical milestone payments made under the License Agreement, were reported in other long-term assets and accrued liabilities, respectively.  Amortization expense was $0.2 million and $0.1 million for the three months ended June 30, 2017 and June 30, 2016, respectively.  Amortization expense was $0.3 million and $0.1 million for the six months ended June 30, 2017 and June 30, 2016, respectively. 

The estimated remaining useful life of the intangible asset is seven years. The table below represents future amortization expense as of June 30, 2017:

(In thousands)
2017	$	669
2018		1,338

The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be 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 no impairment losses for the periods ended June 30, 2017 and December 31, 2016.

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 are the same because all outstanding common stock equivalents have been excluded, as they are anti-dilutive due to 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:

	June 30,
(In thousands)	2017	2016
Shares issuable upon exercise of stock options	3,513	5,181
Shares issuable upon the release of restricted stock awards	5,424	5,977
	8,937	11,158

Revenue Recognition

Laboratory Service Revenue.The Company’s laboratory service revenues are generated by performing diagnostic services using our Cologuard test, and the service is completed upon delivery of a test result to an ordering physician. The Company recognizes revenue in accordance with the provisions of ASC 954-605, Health Care Entities - Revenue Recognition.  The Company recognizes revenue on an accrual basis, net of contractual and other adjustments, when amounts that will ultimately be collected can be reasonably estimated. Contractual and other adjustments represent the difference between the list price (the billing rate) and the estimated aggregate reimbursement rate from payers and patients. 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.

The estimates of amounts that will ultimately be collected requires significant judgment by management, and the Company’s judgments will continue to evolve as it gains payment experience with payers and patients.  Historically, in the absence of the ability to reasonably estimate the amount that will ultimately be collected for services, revenue was recognized upon cash receipt. Effective during the first quarter of 2017, the Company determined that it had the ability to reasonably estimate the amount that will ultimately be collected from all payers, including the impact of patient cost-share collections. Accordingly, the Company now recognizes revenue on an accrual basis for all billed claims.

The components of laboratory service revenue, as recognized upon accrual or cash receipt, for the three and six months ended June 30, 2017 and 2016 were as follows:

	Three Months Ended June 30,				Six Months Ended June 30,

Total	$	57,646	$	21,185	$	106,009	$	36,020

Inventory

Inventory is stated at the lower of cost or market value (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 or has a cost basis in excess of its estimated net realizable value, and records a charge to cost of sales for such inventory, as appropriate. In addition, the Company's products are subject to strict quality control and monitoring which the Company performs throughout the manufacturing process. If certain batches or units of product no longer meet quality specifications or become obsolete due to expiration, the Company records a charge to cost of sales to write down such unmarketable inventory to its estimated net realizable value.

Direct and indirect manufacturing costs incurred during process validation and for other research and development activities, which are not permitted to be sold, have been expensed to research and development. 

Inventory consists of the following:

	June 30,		December 31,
(In thousands)	2017		2016
Raw materials	$	5,009	$	2,408
Semi-finished and finished goods		7,401		4,425
Total inventory	$	12,410	$	6,833

Foreign Currency Translation

For the Company’s international subsidiaries, the local currency is the functional currency. Assets and liabilities of these subsidiaries are translated into United States dollars at the period-end exchange rate or historical rates, as appropriate. Condensed consolidated statements of operations are translated at average exchange rates for the period.

MAYO LICENSE AGREEMENT

MAYO LICENSE AGREEMENT

(3) MAYO LICENSE AGREEMENT

Overview

As more fully described in the 2016 Form 10-K, in June 2009 the Company entered into a patent license agreement with MAYO Foundation for Medical Education and Research (“MAYO”). The Company’s license agreement with MAYO was amended and restated in February 2015 and further amended in January 2016. Under the license agreement, MAYO granted the Company an exclusive, worldwide license to certain MAYO patents and patent applications, as well as a non-exclusive, worldwide license with regard to certain MAYO know-how. As expanded by the January 2016 amendment to the license agreement, the scope of the license includes any screening, surveillance or diagnostic tests or tools for use in connection with any type of cancers, pre-cancers, diseases or conditions.

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 products using the licensed MAYO intellectual property, with minimum annual royalty fees of $25,000 each year through 2033, the year the last patent expires. The January 2016 amendment to the MAYO license agreement established various low-single-digit royalty rates on net sales of current and future products and clarified how net sales will be calculated.  As part of the amendment, the royalty rate on the Company’s net sales of Cologuard increased and, if in the future, improvements are made to the Cologuard product, the royalty rate may further increase, but, pursuant to the terms of the January 2016 amendment, would remain a low-single-digit percentage of net sales.

In addition to royalties, the Company is required to pay MAYO cash of $0.2 million, $0.8 million and $2.0 million upon each product reaching $5.0 million, $20.0 million and $50.0 million in cumulative net sales, respectively.

As part of the February 2015 amendment and restatement of the license agreement, the Company agreed to pay MAYO an additional $5.0 million, payable in five annual installments, through 2019. The Company paid MAYO the annual installment of $1.0 million in the first quarter of each of 2015 and 2016. The Company paid MAYO the 2017 installment in December 2016. The Company records the $1.0 million installments to prepaid expenses and other current assets and amortizes each installment over a twelve-month period commencing on February 1 of each year. For the three and six months ended June 30, 2017 and 2016 the Company has recorded $0.3 million and $0.5 million in amortization of the installments, respectively.

In addition, the Company is paying MAYO for research and development efforts. As part of the Company’s research collaboration with MAYO, the Company incurred charges of $1.1 million and $2.2 million for the three and six months ended June 30, 2017, respectively. The Company made payments of $0.5 million and $1.8 million for the three and six months ended June 30, 2017, respectively. The Company recorded an estimated liability of $1.2 million for research and development efforts as of June 30, 2017. The Company incurred charges of $0.8 million and $1.8 million for the three and six months ended June 30, 2016, respectively. The Company made payments of $1.3 million and $2.4 million for the three and six months ended June 30, 2016, respectively. The Company recorded an estimated liability of $0.7 million for research and development efforts as of June 30, 2016.

Stock-Based Compensation Plans

The Company maintains the 2010 Omnibus Long-Term Incentive Plan (As Amended and Restated Effective April 28, 2015), the 2010 Employee Stock Purchase Plan, the 2015 Inducement Award Plan, the 2016 Inducement Award Plan and the 2000 Stock Option and Incentive Plan (collectively, the “Stock Plans”).

Stock-Based Compensation Expense

The Company records stock-based compensation expense in connection with the amortization of restricted stock and restricted stock unit awards, stock purchase rights granted under the Company’s employee stock purchase plan and stock options granted to employees, non-employee consultants and non-employee directors. The Company recorded $6.1 million and $12.2 million in stock-based compensation expense during the three and six months ended June 30, 2017, respectively. The Company recorded $4.5 million and $10.6 million in stock-based compensation expense during the three and six months ended June 30, 2016, respectively.

Determining Fair Value

Valuation and Recognition – The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. The fair value of each market measure-based award is estimated on the date of grant using a Monte Carlo simulation 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 issued to non-employees, the measurement date is the date when the performance is complete or when the award vests, whichever is the earliest. Accordingly, non-employee awards are re-measured at each reporting period until the final measurement date. The fair value of the award is recognized as stock-based compensation expense over the requisite service period, generally the vesting period. The Black-Scholes and Monte Carlo pricing models utilize 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 used in the Black-Scholes and Monte Carlo valuation models on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent expected term.

Forfeitures – Beginning in 2017, the Company adopted Accounting Standards Update (“ASU”) No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“Update 2016-09”). With the adoption of Update 2016-09, forfeiture estimates are no longer required, and the effects of actual forfeitures are recorded at the time they occur. The impact on the condensed consolidated balance sheet was a cumulative-effect adjustment of $0.4 million, increasing opening accumulated deficit and additional paid-in capital.

The fair value of each option and market measure-based award is based on the assumptions in the following table:

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

(5) FAIR VALUE MEASUREMENTS

The Financial Accounting Standards Board has issued authoritative guidance which requires that 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 the 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.

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.

Fixed-income securities and mutual funds are valued using a third-party pricing agency. The valuation is based on observable inputs including pricing for similar assets and other observable market factors. There has been no material change from period to period.  The estimated fair value of the Company’s long-term debt based on a market approach was approximately $4.6 million and $4.7 million as of June 30, 2017 and December 31, 2016, respectively, and represent Level 2 measurements.  When determining the estimated fair value of the Company’s long-term debt, the Company used market-based risk measurements, such as credit risk.

The following table presents the Company’s fair value measurements as of June 30, 2017 along with the level within the fair value hierarchy in which the fair value measurements in their entirety fall.

As more fully described in the 2016 Form 10-K, 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 one of its Madison, Wisconsin facilities.  This financing arrangement was structured with an unrelated third party financial institution, 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 $2.4 million was recorded in Other Long-Term Liabilities on the consolidated balance sheets. The benefit of this net $2.4 million contribution will be recognized as a decrease in expenses, included in cost of sales, as the Company amortizes the contribution liability over the seven-year compliance period as it is being earned through the Company’s on-going compliance with the conditions of the NMTC program. The Company has recorded $0.1 million and $0.2 million as a decrease of expenses for the three and six months ended June 30, 2017, respectively. At June 30, 2017, the remaining balance of $1.5 million is included in Other Long-Term Liabilities. The Company recorded $0.1 million and $0.2 million as a decrease of expenses for the three and six months ended June 30, 2016, respectively. At June 30, 2016, the remaining balance of $1.9 million was included in Other Long-Term Liabilities. The Company incurred approximately $0.2 million of debt issuance costs related to the above transactions, which are recorded as a direct deduction from the liability. The debt issuance costs are being amortized over the life of the agreements.

WISCONSIN ECONOMIC DEVELOPMENT TAX CREDITS

(8) 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 if the Company expends $26.3 million in capital investments and establishes and maintains 758 full-time positions in the state of Wisconsin over a seven-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-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-year period.

As of June 30, 2017, the Company has earned $5.9 million of tax credits and has received payment of $1.1 million from the WEDC. The unpaid portion is $4.8 million, of which $1.3 million is reported in prepaid expenses and other current assets and $3.5 million is reported in other long-term assets, reflecting when collection of the refundable tax credits is expected to occur. As of June 30, 2017, the Company also has recorded a $1.3 million liability in other short-term liabilities and a $3.1 million liability in other long-term liabilities, reflecting when the expected benefit of the tax credit amortization will reduce future operating expenses.

During the three and six months ended June 30, 2017, the Company amortized $0.3 million and $0.6 million, respectively, of the tax credits earned as a reduction of operating expenses. During the three and six months ended June 30, 2016, the Company amortized $0.2 million and $0.3 million, respectively, of the tax credits earned as a reduction of operating expenses.

In May 2014, the Financial Accounting Standards Board issued ASU No. 2014-9, Revenue from Contracts with Customers (Topic 606), (the “New Revenue Standard”) requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Additional disclosures will also be required to enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The New Revenue Standard will replace most existing revenue recognition guidance in GAAP when it becomes effective and permits the use of either the retrospective or modified retrospective method upon adoption. Adoption of the New Revenue Standard is permitted as early as the first quarter of 2017 and is required by the first quarter of 2018. The Company does not plan to early adopt this standard and has not yet selected a transition method. The Company has completed its preliminary evaluation of the potential financial statement impact of the New Revenue Standard on prior and future reporting periods. The Company does not expect material changes to the timing of when the Company recognizes revenue or the method by which the Company measures its single revenue stream, lab service revenue. Further, regarding the contract acquisition cost component of the New Revenue Standard, the Company’s analysis supports use of the practical expedient when recognizing expense related to incremental costs incurred to acquire a contract, as the recovery of such costs is completed in less than one year’s time. Additionally, incremental costs to obtain contracts have been immaterial to date. Accordingly, the Company does not expect any material changes to the timing of when it recognizes expenses related to contract acquisition costs. The Company will continue its evaluation of the New Revenue Standard through the date of adoption.

In February 2016, the Financial Accounting Standards Board issued ASU No. 2016-02, Leases (Topic 842), (“Update 2016-02”) which requires recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP.   The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Early adoption is permitted. The Company is currently evaluating the effects that the adoption of Update 2016-02 will have on the Company’s consolidated financial statements, and anticipate that the new guidance will impact the Company’s consolidated financial statements as it has several leases.

In August 2016, the Financial Accounting Standards Board issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, (“Update 2016-15”). Current GAAP either is unclear or does not include specific guidance on the eight cash flow classification issues included in the amendments in Update 2016-15. The amendments are an improvement to GAAP because they provide guidance for each of the eight issues, thereby reducing the current and potential future diversity in practice.  The amendments in Update 2016-15 are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company has evaluated Update 2016-15 and does not expect the adoption of this guidance to have a material impact on its statements of cash flows.

In October 2016, the Financial Accounting Standards Board issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, (“Update 2016-16”). This amendment improves the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Update 2016-16 is effective for fiscal years and interim periods within those years beginning after December 15, 2017. Early adoption is permitted. The Company does not expect the adoption of Update 2016-16 to have a significant impact on its consolidated financial statements.

In October 2016, the Financial Accounting Standards Board issued ASU No. 2016-17, Consolidation (Topic 810): Interests Held through Related Parties That Are Under Common Control, (“Update 2016-17”). The amendments in Update 2016-17 change how a reporting entity that is the single decision maker of a variable interest entity should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that variable interest entity. The amendment is effective for fiscal years and interim periods within those years beginning after December 15, 2016. The Company adopted this guidance during the three months ended March 31, 2017. The impact of adoption did not have an impact on the Company’s consolidated financial statements.

In November 2016, the Financial Accounting Standards Board issued ASU No. 2016-18, Statement of Cash Flows; Restricted Cash, (“Update 2016-18”). Update 2016-18 provides guidance on the classification of restricted cash in the statement of cash flows. The amendments are effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted. The amendments in Update 2016-18 should be adopted on a retrospective basis. The Company does not expect the adoption of this amendment to have a material effect on its consolidated financial statements, as the Company does not have restricted cash.

In January 2017, the Financial Accounting Standards Board issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, (“Update 2017-01”) in an effort to clarify the definition of a business, with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in Update 2017-01 are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In January 2017, the Financial Accounting Standards Board issued ASU No. 2017-03, Accounting Changes and Error Corrections, (“Update 2017-03”) which states that an entity should evaluate ASUs, that have been issued but not yet adopted, to determine the effects of those ASUs on the entity’s financial statements when adopted. If the effect is unknown or cannot be reasonably estimated, then additional qualitative disclosures should be considered, including a description of the effect of the accounting policies that the entity expects to apply, if determined, and a comparison to the entity’s current accounting policies, a description of the status of the entity’s process to implement the new standard and the significant implementation matters yet to be addressed. Transition guidance in certain issued but not yet adopted ASUs was updated to reflect Update 2017-03. Other than enhancements to the qualitative disclosures regarding the future adoption of new ASUs, adoption of Update 2017-03 is not expected to have any impact on the Company’s consolidated financial statements.

In May 2017, the Financial Accounting Standards Board issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting, (“Update 2017-09”). Update 2017-09 provides guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The amendments in Update 2017-09 are effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted. The amendments in Update 2017-09 should be applied prospectively to an award modified on or after the adoption date. The Company is currently evaluating the impact of this amendment on the Company’s consolidated financial statements.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of the Company’s wholly owned subsidiaries, Exact Sciences Laboratories, LLC, Exact Sciences Finance Corporation, Exact Sciences Europe LTD, Beijing Exact Sciences Medical Technology Company Limited, and variable interest entities. All significant intercompany transactions and balances have been eliminated in consolidation.

References to “Exact”, “we”, “us”, “our”, or the “Company” refer to Exact Sciences Corporation and its wholly owned subsidiaries.

Use of Estimates

Use of Estimates

The preparation of 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.  Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers cash on hand, demand deposits in bank, money market funds, and all highly liquid investments with an original maturity of 90 days or less to be cash and cash equivalents.

Marketable Securities

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 when the Company has the positive intent and ability to hold the securities to maturity. Marketable equity securities and debt securities not classified as held-to-maturity are classified as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and losses, net of tax, reported in other comprehensive loss. 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. Realized gains and losses and declines in value judged to be other-than-temporary on available-for-sale securities are included in investment income. 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.

At June 30, 2017 and December 31, 2016, the Company’s investments were comprised of fixed income investments, and all were deemed available-for-sale. The objectives of the Company’s investment strategy are to provide liquidity and safety of principal while striving to achieve the highest rate of return consistent with these two objectives.  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 support its current operations (including those with a contractual term greater than one year from the date of purchase), are classified as current. All of the Company’s investments are considered current. There were no realized losses for the six months ended June 30, 2017 and 2016. Realized gains were $10,000 and $18,000 for the six months ended June 30, 2017 and 2016, respectively.

We periodically review our investments in unrealized loss positions for other-than-temporary impairments. This evaluation includes, but is not limited to, significant quantitative and qualitative assessments and estimates regarding credit ratings, collateralized support, the length of time and significance of a security’s loss position, our intent not to sell the security, and whether it is more likely than not that we will have to sell the security before recovery of its cost basis. For the six months ended June 30, 2017, no investments were identified with other-than-temporary declines in value.

Available-for-sale securities at June 30, 2017 consisted of the following:

Total reclassifications		$	(4)	$	39

Property and Equipment

Property and Equipment

Property and equipment are stated at cost and depreciated using the straight-line method over the assets’ estimated useful lives. Maintenance and repairs are expensed when incurred; additions and improvements are capitalized. The estimated useful lives of fixed assets are as follows:

	Estimated
Asset Classification	Useful Life
Laboratory equipment	3 - 5 years
Computer equipment and computer software	3 years
Leasehold improvements	Lesser of the remaining lease term or useful life
Building Improvements	Lesser of the remaining building life or useful life
Furniture and fixtures	3 years
Buildings	30 years

At June 30, 2017, the Company had $9.1 million of assets under construction which consisted of $1.2 million related to leasehold improvements, $2.7 million related to computer equipment and computer software projects and $5.2 million related to machinery and equipment. Depreciation will begin on these assets once they are placed into service. The Company expects to incur an additional $13.2 million to complete the leasehold improvements, $0.3 million to complete the computer equipment and computer software projects, and $10.6 million to complete the machinery and equipment. These projects are expected to be completed in 2017 and 2018. There were no impairment losses for the periods ended June 30, 2017 and December 31, 2016.

Software Capitalization Policy

Software Capitalization Policy

Software development costs related to internal use software are incurred in three stages of development: the preliminary project stage, the application development stage, and the post-implementation stage. Costs incurred during the preliminary project and post-implementation stages are expensed as incurred. Costs incurred during the application development stage that meet the criteria for capitalization are capitalized and amortized, when the software is ready for its intended use, using the straight-line basis over the estimated useful life of the software.

Patent Costs and Intangible Asset

Patent Costs and Intangible Assets

Patent costs, which have historically consisted of related legal fees, are capitalized as incurred, only if the Company determines that there is some probable future economic benefit to be 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. The Company determined that all patent costs incurred during the six months ended June 30, 2017 should be expensed and not capitalized as the future economic benefit to be derived from the transactions cannot be determined.

Under a technology license and royalty agreement entered into with MDxHealth (“MDx”), dated July 26, 2010 (as subsequently amended, the “License Agreement”), the Company was required to pay MDx milestone-based royalties on sales of products or services covered by the licensed intellectual property. Once the achievement of a milestone occurred or was considered probable, an intangible asset and corresponding liability was reported in other long-term assets and accrued liabilities, respectively. The intangible asset is being amortized over the estimated ten-year useful life of the licensed intellectual property through 2024, and such amortization is reported in cost of sales. The liability was relieved once the milestone was achieved and payment was made. Payment for all remaining milestones under the License Agreement was made as part of the Royalty Buy-Out agreement outlined below.

Effective April 25, 2017, the Company and MDx entered into a Royalty Buy-Out Agreement (“Royalty Buy-Out Agreement”), which terminated the License Agreement.  Pursuant to the Royalty Buy-Out Agreement, the Company paid MDx a one-time fee of $8.0 million in exchange for an assignment of certain patents covered by the License Agreement and the elimination of all ongoing royalties and other payments by the Company to MDx under the License Agreement.  Also included in the Royalty Buy-Out Agreement is a mutual release of liabilities, which includes all amounts previously accrued under the License Agreement.  Concurrently with entering into the Royalty Buy-Out Agreement, the Company entered into a Patent Purchase Agreement (“Patent Purchase Agreement”) with MDx under which it paid MDx an additional $7.0 million in exchange for the assignment of certain other patent rights that were not covered by the License Agreement. The total $15.0 million paid by the Company pursuant to the Royalty Buy-Out Agreement and Patent Purchase Agreement, net of liabilities relieved of $6.6 million, was recorded as an intangible asset and is being amortized over the estimated ten-year useful life of the licensed intellectual property, and such amortization is reported in cost of sales. The $6.6 million of liabilities relieved were related to historical milestones and accrued royalties under the License Agreement.

As of June 30, 2017, an intangible asset of $9.7 million related to historical milestone payments made under the License Agreement and intangible assets acquired as part of the Royalty Buy-Out Agreement and Patent Purchase Agreement is reported in other long-term assets.  As of December 31, 2016, an intangible asset of $1.6 million and a liability of $1.3 million related to historical milestone payments made under the License Agreement, were reported in other long-term assets and accrued liabilities, respectively.  Amortization expense was $0.2 million and $0.1 million for the three months ended June 30, 2017 and June 30, 2016, respectively.  Amortization expense was $0.3 million and $0.1 million for the six months ended June 30, 2017 and June 30, 2016, respectively. 

The estimated remaining useful life of the intangible asset is seven years. The table below represents future amortization expense as of June 30, 2017:

(In thousands)
2017	$	669
2018		1,338
2019		1,338
2020		1,338
2021		1,338

The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be 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 no impairment losses for the periods ended June 30, 2017 and December 31, 2016.

Net Loss Per Share

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 are the same because all outstanding common stock equivalents have been excluded, as they are anti-dilutive due to 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:

	June 30,
(In thousands)	2017	2016
Shares issuable upon exercise of stock options	3,513	5,181
Shares issuable upon the release of restricted stock awards	5,424	5,977
	8,937	11,158

Revenue Recognition

Revenue Recognition

Laboratory Service Revenue.The Company’s laboratory service revenues are generated by performing diagnostic services using our Cologuard test, and the service is completed upon delivery of a test result to an ordering physician. The Company recognizes revenue in accordance with the provisions of ASC 954-605, Health Care Entities - Revenue Recognition.  The Company recognizes revenue on an accrual basis, net of contractual and other adjustments, when amounts that will ultimately be collected can be reasonably estimated. Contractual and other adjustments represent the difference between the list price (the billing rate) and the estimated aggregate reimbursement rate from payers and patients. 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.

The estimates of amounts that will ultimately be collected requires significant judgment by management, and the Company’s judgments will continue to evolve as it gains payment experience with payers and patients.  Historically, in the absence of the ability to reasonably estimate the amount that will ultimately be collected for services, revenue was recognized upon cash receipt. Effective during the first quarter of 2017, the Company determined that it had the ability to reasonably estimate the amount that will ultimately be collected from all payers, including the impact of patient cost-share collections. Accordingly, the Company now recognizes revenue on an accrual basis for all billed claims.

The components of laboratory service revenue, as recognized upon accrual or cash receipt, for the three and six months ended June 30, 2017 and 2016 were as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
(In thousands)	2017		2016		2017		2016
Revenue recognized on an accrual basis	$	57,646	$	19,579	$	101,500	$	33,255
Revenue recognized when cash is received		—		1,606		4,509		2,765
Total	$	57,646	$	21,185	$	106,009	$	36,020

Inventory

Inventory

Inventory is stated at the lower of cost or market value (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 or has a cost basis in excess of its estimated net realizable value, and records a charge to cost of sales for such inventory, as appropriate. In addition, the Company's products are subject to strict quality control and monitoring which the Company performs throughout the manufacturing process. If certain batches or units of product no longer meet quality specifications or become obsolete due to expiration, the Company records a charge to cost of sales to write down such unmarketable inventory to its estimated net realizable value.

Direct and indirect manufacturing costs incurred during process validation and for other research and development activities, which are not permitted to be sold, have been expensed to research and development. 

Inventory consists of the following:

	June 30,		December 31,
(In thousands)	2017		2016
Raw materials	$	5,009	$	2,408
Semi-finished and finished goods		7,401		4,425
Total inventory	$	12,410	$	6,833

Foreign Currency Translation

Foreign Currency Translation

For the Company’s international subsidiaries, the local currency is the functional currency. Assets and liabilities of these subsidiaries are translated into United States dollars at the period-end exchange rate or historical rates, as appropriate. Condensed consolidated statements of operations are translated at average exchange rates for the period. The cumulative translation adjustments resulting from changes in exchange rates are included in the condensed consolidated balance sheet as a component of accumulated other comprehensive loss in total Exact Sciences Corporation’s stockholders’ equity. Transaction gains and losses are included in the condensed consolidated statement of operations.

Reclassifications

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation in the condensed consolidated financial statements and accompanying notes to the condensed consolidated financial statements.
