ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Depomed, Inc. (Depomed or the Company) is a specialty pharmaceutical company focused on pain and other central nervous system (CNS) conditions. The products that comprise the Company’s current specialty pharmaceutical business are (i) NUCYNTA® ER (tapentadol extended release tablets), a product for the management of pain severe enough to require daily, around-the-clock, long term opioid treatment, including neuropathic pain associated with diabetic peripheral neuropathy (DPN) in adults, and for which alternative treatment options are inadequate, and NUCYNTA® IR (NUCYNTA) (tapentadol), a product for the management of moderate to severe acute pain in adults, each of which the Company acquired the United States (U.S.) rights to in April 2015, (ii) Gralise® (gabapentin), a once-daily product for the management of postherpetic neuralgia (PHN) that the Company launched in October 2011, (iii) CAMBIA® (diclofenac potassium for oral solution), a product for the acute treatment of migraine attacks that the Company acquired in December 2013, (iv) Zipsor® (diclofenac potassium) liquid filled capsules, a product for the treatment of mild to moderate acute pain that the Company acquired in June 2012, and (v) Lazanda® (fentanyl) nasal spray, a product for the management of breakthrough pain in cancer patients 18 years of age and older who are already receiving and who are tolerant to opioid therapy for their underlying persistent cancer pain that the Company acquired in July 2013.

The Company also has a portfolio of royalty and milestone producing license agreements based on its proprietary Acuform® gastroretentive drug delivery technology with Mallinckrodt Inc. (Mallinckrodt), Ironwood Pharmaceuticals, Inc. (Ironwood) and Janssen Pharmaceuticals, Inc. (Janssen Pharma).

On October 18, 2013, the Company sold its interests in royalty and milestone payments under its license agreements in the Type 2 diabetes therapeutic area to PDL BioPharma, Inc. (PDL) for $240.5 million (the PDL Transaction). The interests sold include royalty and milestone payments accruing from and after October 1, 2013 from (a) Salix Pharmaceuticals, Inc. (Salix) with respect to sales of Glumetza® (metformin HCL extended-release tablets) in the U.S; (b) Merck & Co., Inc. (Merck) with respect to sales of Janumet® XR (sitagliptin and metformin HCL extended-release); (c) Janssen Pharmaceutica N.V. and Janssen Pharma (collectively, Janssen) with respect to potential future development milestones and sales of Janssen’s investigational fixed-dose combination of Invokana® (canagliflozin) and extended-release metformin; (d) Boehringer Ingelheim International GMBH (Boehringer Ingelheim) with respect to potential future development milestones and sales of the investigational fixed-dose combinations of drugs and extended-release metformin subject to the Company's license agreement with Boehringer Ingelheim; and (e) LG Life Sciences Ltd. and Valeant International Bermuda SRL for sales of extended-release metformin in Korea and Canada, respectively.

As of December 31, 2016, the Company has one product candidate under clinical development, cebranopadol for chronic nociceptive and neuropathic pain.

Basis of Presentation

Basis of Preparation

The Company’s consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP and US Securities and Exchange Commission (SEC) regulations for annual reporting.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Depomed Bermuda Ltd (Depo Bermuda), Depo NF Sub, LLC (Depo NF Sub) and Depo DR Sub, LLC (Depo DR Sub). All intercompany accounts and transactions have been eliminated on consolidation.

On November 17, 2015, the Company entered into a definitive agreement to acquire the U.S. and Canadian rights to cebranopadol and its related follow-on compound from Grünenthal GmbH (Grünenthal). The acquisition of these rights closed on December 30, 2015 at which point the Company assigned its rights under the agreement to Depo Bermuda, a Company which was formed in Bermuda on December 22, 2015.

Depo NF Sub was formed on March 26, 2015, in connection with a Note Purchase Agreement dated March 12, 2015 (Note Purchase Agreement) governing the Company’s issuance of $575.0 million aggregate principal amount of Senior Notes on April 2, 2015, for aggregate gross proceeds of approximately $562.0 million. On April 2, 2015, the Company and Depo NF Sub entered into a Pledge and Security Agreement with the Collateral Agent pursuant to which the Company and Depo NF Sub each granted the Collateral Agent (on behalf of the Purchasers) a security interest in substantially all of their assets, other than specifically excluded assets.

Depo DR Sub was formed in October 2013 for the sole purpose of facilitating the PDL Transaction. The Company contributed to Depo DR Sub all of its rights, title and interests in each of the license agreements to receive royalty and milestone payments. Immediately following the transaction, Depo DR Sub sold to PDL, among other things, such rights to receive royalty and milestone payments, for an upfront cash purchase price of $240.5 million.

The Company and Depo DR Sub continue to retain certain administrative duties and obligations under the specified license agreements. These include the collection of the royalty and milestone amounts due and enforcement of related provisions under the specified license agreements, among others. In addition, the Company and Depo DR Sub must prepare a quarterly distribution report relating to the specified license agreements, containing, among other items, the amount of royalty payments received by the Company, reimbursable expenses and set‑offs. The Company and Depo DR Sub must also provide PDL with notice of certain communications, events or actions with respect to the specified license agreements and infringement of any underlying intellectual property.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates are used when accounting for amounts recorded in connection with acquisitions, including initial fair value determinations of assets and liabilities as well as subsequent fair value measurements. Additionally, estimates are used in determining items such as sales discounts and returns, depreciable and amortizable lives, share-based compensation assumptions and taxes on income. Although management believes these estimates are based upon reasonable assumptions within the bounds of its knowledge of the Company’s business and operations, actual results could differ materially from these estimates.

Cash, Cash Equivalents, Short-term Investments and Marketable Securities

The Company considers all highly liquid investments with an original maturity (at date of purchase) of three months or less to be cash equivalents. All marketable securities with original maturities at the date of purchase greater than three months and remaining maturities of less than one year are classified as short-term investments. All marketable securities with original maturities at the date of purchase greater than one year are classified as marketable securities, long term. Cash and cash equivalents consist of cash on deposit with banks, money market instruments and commercial paper. The Company places its cash, cash equivalents, short-term investments and marketable securities with high quality U.S. government and financial institutions and to date has not experienced material losses on any of its balances. The Company records cash and cash equivalents at amortized cost, which approximates the fair value. All marketable securities are classified as available-for-sale since these instruments are readily marketable. These securities are carried at fair value, which is based on readily available market information, with unrealized gains and losses included in accumulated other comprehensive loss within shareholders’ equity.

The Company uses the specific identification method to determine the amount of realized gains or losses on sales of marketable securities. We regularly review all of our investments for other-than-temporary declines in fair value. Our review includes the consideration of the cause of the impairment including the creditworthiness of the security issuers, the number of securities in an unrealized loss position and the severity and duration of the unrealized losses. When we determine that the decline in fair value of an investment is below our accounting basis and this decline is other-than-temporary, we reduce the carrying value of the security we hold and record a loss in the amount of such decline. Realized gains or losses have been insignificant and are included in interest and other income in the consolidated statements of operations.

Accounts Receivable

Trade accounts receivable are recorded net of allowances for cash discounts for prompt payment. To date the Company has not recorded a bad debt allowance since that the majority of its product revenue comes from sales to a limited number of financially sound companies who have historically paid their balances timely. The need for bad debt allowance is evaluated each reporting period based on our assessment of the credit worthiness of our customers or any other potential circumstances that could result in bad debt.

Receivables from collaborative partners represent amounts due from Janssen and Tribute Pharmaceuticals Canada, Inc.

Inventories

Inventories are stated at the lower of cost or market with cost determined by specific manufactured lot. Inventories consist of costs of the active pharmaceutical ingredient, contract manufacturing and packaging costs. The Company writes-off the value of inventory for potentially excess, dated or obsolete inventories based on an analysis of inventory on hand and projected demand.

Recognizing and Measuring Assets Acquired and Liabilities Assumed in Business Combinations at Fair Value

The Company accounts for acquired businesses using the acquisition method of accounting, which requires that assets acquired and liabilities assumed be recorded at date of acquisition at their respective fair values. The fair value of the consideration paid, including contingent consideration, is assigned to the underlying net assets of the acquired business based on their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill or bargain purchase, as applicable.

Significant judgments are used in determining the estimated fair values assigned to the assets acquired and liabilities assumed and in determining estimates of useful lives of long-lived assets. Fair value determinations and useful life estimates are based on, among other factors, estimates of expected future net cash flows, estimates of appropriate discount rates used to present value expected future net cash flows, the assessment of each asset’s life cycle, and the impact of competitive trends on each asset’s life cycle and other factors. These judgments can materially impact the estimates used to allocate acquisition date fair values to assets acquired and liabilities assumed and the resulting timing and amounts charged to, or recognized in current and future operating results. For these and other reasons, actual results may vary significantly from estimated results.

Any changes in the fair value of contingent consideration resulting from a change in the underlying inputs is recognized in operating expenses until the contingent consideration arrangement is settled. Changes in the fair value of contingent consideration resulting from the passage of time are recorded within interest expense until the contingent consideration is settled.

Property and Equipment

Property and equipment are stated at cost, less accumulated depreciation and amortization (See Note 5 of the Notes to the Consolidated Financial Statements). Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, as follows:


Furniture and office equipment		3 - 5 years
Machinery and equipment		5 - 7 years
Laboratory equipment		3 - 5 years
Leasehold improvements		Shorter of estimated useful life or lease term

Intangible Assets

Intangible assets consist of purchased developed technology and trademarks. The Company determines the fair values of acquired intangible assets as of the acquisition date. Discounted cash flow models are typically used in these valuations, which require the use of significant estimates and assumptions, including but not limited to, developing appropriate discount rates and estimating future cash flows from product sales and related expenses. The Company evaluates purchased intangibles for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. Estimating future cash flows related to an intangible asset involves significant estimates and assumptions. If the Company’s assumptions are not correct, there could be an impairment loss or, in the case of a change in the estimated useful life of the asset, a change in amortization expense.

Revenue Recognition

The Company recognizes revenue from the sale of its products, royalties earned, and payments received and services performed under contractual arrangements.

Revenue is recognized when there is persuasive evidence that an arrangement exists, delivery has occurred and title has passed, the price is fixed or determinable and the Company is reasonably assured of collecting the resulting receivable. Revenue arrangements with multiple elements are evaluated to determine whether the multiple elements meet certain criteria for dividing the arrangement into separate units of accounting, including whether the delivered element(s) have stand‑alone value to the Company’s customer or licensee. Where there are multiple deliverables combined as a single unit of accounting, revenues are deferred and recognized over the period that the Company remains obligated to perform services.

Product Sales—The Company sells commercial products to wholesale distributors and retail pharmacies. Products sales revenue is recognized when title has transferred to the customer and the customer has assumed the risks and rewards of ownership, which typically occurs on delivery to the customer.

Product Sales Allowances—The Company recognizes product sales allowances as a reduction of product sales in the same period the related revenue is recognized. Product sales allowances are based on amounts owed or to be claimed on the related sales. These estimates take into consideration the terms of the Company’s agreements with customers, historical product returns, rebates or discounts taken, estimated levels of inventory in the distribution channel, the shelf life of the product and specific known market events, such as competitive pricing and new product introductions. If actual future results vary from the Company’s estimates, the Company may need to adjust these estimates, which could have an effect on product sales and earnings in the period of adjustment. The Company’s sales allowances include:

Product Returns—The Company allows customers to return product for credit with respect to product that is within six months before and up to 12 months after its product expiration date. The Company estimates product returns and associated credit on NUCYNTA ER and NUCYNTA, Gralise, CAMBIA, Zipsor and Lazanda. Estimates for returns are based on historical return trends by product or by return trends of similar products, taking into consideration the shelf life of the product at the time of shipment, shipment and prescription trends, estimated distribution channel inventory levels and consideration of the introduction of competitive products. Under the terms of the Zipsor asset purchase agreement, the Company assumed financial responsibility for returns of Zipsor product previously sold by Xanodyne Pharmaceuticals, Inc. (Xanodyne). Under the terms of the CAMBIA asset purchase agreement, the Company also assumed financial responsibility for returns of CAMBIA® product previously sold by Nautilus. The Company did not assume financial responsibility for returns of NUCYNTA ER and NUCYNTA previously sold by Janssen Pharma or Lazanda product previously sold by Archimedes Pharma US Inc. See Note 13 for further information on the acquisition of NUCYNTA ER and NUCYNTA, CAMBIA, Lazanda and Zipsor.

The shelf life of NUCYNTA ER is 24 months to 36 months and the shelf life of NUCYNTA is 36 months from the date of tablet manufacture. The shelf life of Gralise is 24 to 36 months from the date of tablet manufacture. The shelf life of CAMBIA is 24 to 48 months from the manufacture date. The shelf life of Zipsor is 36 months from the date of tablet manufacture. The shelf life of Lazanda is 24 to 36 months from the manufacture date. Because of the shelf life of the Company’s products and its return policy of issuing credits with respect to product that is returned within six months before and up to 12 months after its product expiration date, there may be a significant period of time between when the product is shipped and when the Company issues credit on a returned product. Accordingly, the Company may have to adjust these estimates, which could have an effect on product sales and earnings in the period of adjustments.

Wholesaler and Retail Pharmacy Discounts — The Company offers contractually determined discounts to certain wholesale distributors and retail pharmacies that purchase directly from it. These discounts are either taken off‑invoice at the time of shipment or paid to the customer on a quarterly basis one to two months after the quarter in which product was shipped to the customer.

Prompt Pay Discounts—The Company offers cash discounts to its customers (generally 2% of the sales price) as an incentive for prompt payment. Based on the Company’s experience, the Company expects its customers to comply with the payment terms to earn the cash discount.

Patient Discount Programs—The Company offers patient discount co‑pay assistance programs in which patients receive certain discounts off their prescriptions at participating retail pharmacies. The discounts are reimbursed by the Company approximately one month after the prescriptions subject to the discount are filled.

Medicaid Rebates—The Company participates in Medicaid rebate programs, which provide assistance to certain low‑income patients based on each individual state’s guidelines regarding eligibility and services. Under the Medicaid rebate programs, the Company pays a rebate to each participating state, generally two to three months after the quarter in which prescriptions subject to the rebate are filled.

Chargebacks—The Company provides discounts to authorized users of the Federal Supply Schedule (FSS) of the General Services Administration under an FSS contract with the Department of Veterans Affairs. These federal entities purchase products from the wholesale distributors at a discounted price, and the wholesale distributors then charge back to the Company the difference between the current retail price and the price the federal entity paid for the product.

Managed Care Rebates—The Company offers discounts under contracts with certain managed care providers. The Company generally pays managed care rebates one to three months after the quarter in which prescriptions subject to the rebate are filled.

Medicare Part D Coverage Gap Rebates—The Company participates in the Medicare Part D Coverage Gap Discount Program under which it provides rebates on prescriptions that fall within the “donut hole” coverage gap. The Company generally pays Medicare Part D Coverage Gap rebates two to three months after the quarter in which prescriptions subject to the rebate are filled.

Royalties—Royalties are recognized as earned in accordance with the contract terms when royalties from licensees can be reliably measured and collectability is reasonably assured.

Royalties received from Mallinckrodt on sales of XARTEMIS™ XR and from Janssen Pharma on sales of NUCYNTA® ER are recognized in the period earned as the royalty amounts can be estimated and collectability is reasonably assured. The Company no longer receives royalties from Janssen Pharma on sales of NUCYNTA® ER in the U.S. for any period after April 2, 2015, the date on which the Company acquired the U.S. rights to NUCYNTA® ER from Janssen Pharma. The Company continues to receive royalties from Janssen Pharma on net sales of NUCYNTA® ER in Canada and Japan.

Until October 1, 2013, the Company received royalties from Salix based on net sales of Glumetza and from Merck based on net sales of Janumet® XR. The royalties were recognized in the period earned as the royalty amounts could be estimated and collectability was reasonably assured.

In October 2013, the Company sold its interests in royalty and milestone payments under its license agreements in the Type 2 diabetes therapeutic area, including the Glumetza royalty and the Janumet® XR royalty , to PDL for $240.5 million. The Company had significant continuing involvement in the PDL transaction until September 30, 2014, primarily due to the Company’s obligation to act as the intermediary for the supply of 1000 mg Glumetza to Salix, the licensee of Glumetza. Under the relevant accounting guidance, because of the Company’s significant continuing involvement, the $240.5 million payment received from PDL was accounted for as debt until September 30, 2014. As a result of debt accounting, even though the Company did not retain the related royalties and milestones under the transaction, the Company was required to record the revenue related to these royalties and milestones in its consolidated statement of operations until September 30, 2014.

Effective October 1, 2014, the Company, Valeant, Salix and PDL executed an amended agreement which eliminated any and all continuing obligations on the part of the Company in the manufacture and supply of 1000 mg Glumetza tablets. Consequently, the entire outstanding balance of the liability related to the sale of future royalties and milestones of approximately $147.0 million was recognized within “Non-cash PDL royalty revenue” during the fourth quarter of 2014.

License and Collaborative Arrangements—Revenue from license and collaborative arrangements is recognized when the Company has substantially completed its obligations under the terms of the arrangement and the Company’s remaining involvement is inconsequential and perfunctory. If the Company has significant continuing involvement under such an arrangement, license and collaborative fees are recognized over the estimated performance period. The Company recognizes milestone payments for its research and development collaborations upon the achievement of specified milestones if (1) the milestone is substantive in nature, and the achievement of the milestone was not reasonably assured at the inception of the agreement, (2) consideration earned relates to past performance and (3) the milestone payment is nonrefundable. A milestone is considered substantive if the consideration earned from the achievement of the milestone is consistent with the Company’s performance required to achieve the milestone or consistent with the increase in value to the collaboration resulting from the Company’s performance; the consideration earned relates solely to past performance; and the consideration earned is reasonable relative to all of the other deliverables and payments within the arrangement. License, milestones and collaborative fee payments received in excess of amounts earned are classified as deferred revenue until earned.

Total revenues are summarized in the following table (in thousands):–

Stock-Based Compensation

Stock‑Based Compensation

Compensation expense for stock-based compensation is based on the single-option approach, includes an estimate for forfeitures and is recognized over the vesting term of the options using the straight-line method. The Company estimates forfeitures based on historical experience. The Company uses historical option exercise data to estimate the expected term of the options.

Research and Development Expense and Accruals

Research and development expenses include salaries, clinical trial costs, consultant fees, supplies, manufacturing costs for research and development programs and allocations of corporate costs. All such costs are charged to research and development expense as incurred. These expenses result from the Company’s independent research and development efforts as well as efforts associated with collaborations. The Company reviews and accrues clinical trial expenses based on work performed, which relies on estimates of total costs incurred based on patient enrollment, completion of patient studies and other events. The Company follows this method since reasonably dependable estimates of the costs applicable to various stages of a research agreement or clinical trial can be made. Accrued clinical costs are subject to revisions as trials progress to completion. Revisions are charged to expense in the period in which the facts that give rise to the revision become known.

Acquired In-Process Research and Development

The initial costs of rights to IPR&D projects acquired in an asset acquisition are expensed as IPR&D unless the project has an alternative future use. Development costs incurred after an acquisition are expensed as incurred.

Shipping and Handling Costs

Shipping and handling costs incurred for product shipments are recorded in cost of sales in the Statements of Operations.

Advertising Costs

Costs associated with advertising are expensed as incurred. Advertising expense for the years ended December 31, 2016, 2015 and 2014 were $4.1 million, $2.3 million and $1.8 million, respectively.

Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes certain changes in equity of the Company that are excluded from net income (loss). Unrealized gains and losses on the Company’s available‑for‑sale securities are reported separately in shareholders’ equity and included in accumulated other comprehensive loss. Comprehensive income (loss) for the years ended December 31, 2016, 2015 and 2014 has been reflected in the consolidated statements of comprehensive income (loss).

Income Taxes

The Company’s income tax policy is to record the estimated future tax effects of temporary differences between the tax bases of assets and liabilities and amounts reported in the Company’s accompanying consolidated balance sheets, as well as operating loss and tax credit carryforwards. The Company follows the guidelines set forth in the applicable accounting guidance regarding the recoverability of any tax assets recorded on the consolidated balance Sheet and provides any necessary allowances as required. Determining necessary allowances requires the Company to make assessments about the timing of future events, including the probability of expected future taxable income and available tax planning opportunities.

The Company is subject to examination of its income tax returns by various tax authorities on a periodic basis. The Company regularly assesses the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of its provision for income taxes. The Company has applied the provisions of the applicable accounting guidance on accounting for uncertainty in income taxes, which requires application of a more-likely-than-not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits the Company to recognize a tax benefit measured at the largest amount of tax benefit that, in the Company’s judgment, is more than 50 percent likely to be realized upon settlement. It further requires that a change in judgment related to the expected ultimate resolution of uncertain tax positions be recognized in earnings in the period of such change.

Segment Information

The Company operates in one operating segment and has operations solely in the United States. To date, all of the Company’s revenues from product sales are related to sales in the United States. The Company has recognized license and royalty revenue from license agreements in the territories of the United States, Canada and Korea.

Concentration of Risk

The Company invests cash that is currently not being used for operational purposes in accordance with its investment policy in low‑risk debt securities of the U.S. Treasury, U.S. government sponsored agencies and very highly rated banks and corporations. The Company is exposed to credit risk in the event of a default by the institutions holding the cash equivalents and available‑for sale securities to the extent recorded on the consolidated balance sheet.

The Company is subject to credit risk from its accounts receivable related to product sales and royalties. The majority of the Company’s trade accounts receivable arises from product sales in the United States. Three wholesale distributors represented 36%, 27% and 25% of product shipments for the year ended December 31, 2016. These three customers individually comprised 39%, 33% and 20%, respectively, of product sales-related accounts receivable as of December 31, 2016. Three wholesale distributors represented 36%, 27% and 24% of product shipments for the year ended December 31, 2015. These three customers individually comprised 38%, 25% and 25%, respectively, of product sales‑related accounts receivable as of December 31, 2015. Three wholesale distributors represented 35%, 27% and 26% of product shipments for the year ended December 31, 2014. These three customers individually comprised 35%, 32% and 33%, respectively, of product sales‑related accounts receivable as of December 31, 2014. Accounts receivable balances related to product sales were $102.1 million and $71.1 million and for the years ended December 31, 2016 and 2015, respectively. The Company relies on a single third‑party contract manufacturer organization in Puerto Rico to manufacture Gralise and one third‑party supplier for the supply of gabapentin, the active pharmaceutical ingredient in Gralise. The Company also relies on single third-party contract suppliers: MiPharm, S.p.A., Accucaps Industries Limited and DPT Lakewood, Inc. for supply of CAMBIA, Zipsor and Lazanda respectively. Janssen Pharmaceuticals is the sole source supplier of NUCYNTA ER and NUCNYTA.

Accounts receivable related to royalties was $0.2 million for the year ended December 31, 2016. Accounts receivable related to royalties was $0.1 million for the year ended December 31, 2015.

To date, the Company has not experienced any losses with respect to the collection of its accounts receivable and believes that its entire accounts receivable balances are collectible.

Recently Issued Accounting Standards

Recent Accounting Pronouncements

In September 2015, the Financial Accounting Standards Board (FASB) issued ASU 2015-16 Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. ASU 2015-16 requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, to record an acquisition-to-date adjustment, in the same period’s financial statements, for the effect on earnings of changes in depreciation, amortization, or other income and to disclose, the amount of such adjustment that related to prior periods. ASU 2015-16 is effective for annual and interim periods beginning after December 15, 2016. The Company adopted the provisions of this guidance in the three months ended March 31, 2016, and the adoption of this guidance did not materially affect our consolidated financial statements.

In November 2015, the FASB issued Accounting Standards Update No. 2015 17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (ASU 2015 17), which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. The updated standard is effective beginning on January 1, 2017 with early application permitted as of the beginning of any interim or annual reporting period. The Company early adopted this standard prospectively as of October 1, 2015.

In April 2015, the FASB issued ASU 2015-05, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40: Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement”. This guidance requires customers in a cloud computing arrangement to evaluate whether the arrangement includes a software license. If the arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for the arrangement as a service contract. ASU 2015-05 is effective for annual and interim periods beginning after December 15, 2015. The Company adopted the provisions of this guidance prospectively in the three months ended March 31, 2016, and the adoption of this guidance did not materially affect our consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11 Inventory (Topic 330): Simplifying the Measurement of Inventory. ASU 2015-11 requires an entity to measure inventory, other than inventory accounted for under last-in, first-out method or retail inventory method, at the lower of cost or net realizable value. ASU 2015-11 is effective for annual and interim periods beginning after December 15, 2016 on a prospective basis. The Company plans to adopt this guidance on January 1, 2017. We do not expect the adoption of ASU 2015-11 to materially affect our consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, "Interest - Imputation of Interest – Simplifying the Presentation of Debt Issuance Costs". This guidance requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this Update. The guidance is effective for annual periods beginning after December 15, 2015, and interim periods thereafter, but requires retrospective adjustment with early adoption permitted. The Company adopted the provisions of this guidance as of January 1, 2016 and, consequently, $5.7 million and $0.5 million of debt issuance costs presented within long term “other assets” in the Company’s consolidated balance sheet as of December 31, 2015 have been reclassified against the long term liability for the Convertible Notes and the Senior Notes, respectively.

In May 2014, the FASB issued Accounting Standards Update (ASU or Update) No. 2014-09, "Revenue from Contracts with Customers". This guidance outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. On July 9, 2015, the FASB deferred the effective date of this Update to fiscal years beginning after December 15, 2017, with early adoption permitted on the original effective date of fiscal years beginning after December 15, 2016. This guidance can be adopted on a full retrospective basis or on a modified retrospective basis. We plan to adopt this guidance on January 1, 2018, using the modified retrospective transition method applied to those contracts which were not completed as of that date. Upon adoption, we will recognize the cumulative effect of adopting this guidance as an adjustment to our opening balance of accumulated deficit. Prior periods will not be retrospectively adjusted. The Company has substantially completed an analysis of existing contracts with its customers and has assessed the differences in accounting for such contracts under this guidance compared with current revenue accounting standards. Based on its review of current customer contracts, the Company does not expect the implementation of this guidance to have a material impact on its consolidated financial statements as the timing of revenue recognition for product sales is not expected to significantly change.

In February 2016, the FASB issued ASU No. 2016-02, "Leases". This guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than twelve months regardless of classification. If the available accounting election is made, leases with a term of twelve months or less can be accounted for similar to existing guidance for operating leases. For a public entity, the amendments in this guidance are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in this guidance is permitted for all entities. The Company is currently evaluating and has not yet determined the impact implementation will have on the Company’s consolidated financial statements.

In March 2016, the FASB issued ASU No 2016-09 “Improvements to Employee Share-Based Payment Accounting”. This guidance simplifies the accounting for the taxes related to stock based compensation, requiring excess tax benefits and deficiencies to be recognized as a component of income tax expense rather than equity. This guidance also requires excess tax benefits and deficiencies to be presented as an operating activity on the statement of cash flows and allows an entity to make an accounting policy election to either estimate expected forfeitures or to account for them as they occur. The Company will adopt this ASU in the first quarter of 2017. The inclusion of excess tax benefits and deficiencies as a component of our income tax expense will increase volatility within our provision for income taxes as the amount of excess tax benefits or deficiencies from stock-based compensation awards are dependent on our stock price at the date the awards vest. The magnitude of such impacts will depend upon future movements in our share price as well as the timing of stock award exercises, which are both difficult to estimate. The Company will elect to account for forfeitures as they occur, rather than estimate expected forfeitures.

In August 2016, the FASB issued guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The guidance is effective for the Company in the first quarter of fiscal 2018 and will be applied on a retrospective basis. Early adoption is permitted. The Company is currently evaluating and has not yet determined the impact implementation will have on the Company’s consolidated financial statements.
