Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement. In addition, entities will recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Under current guidance, excess tax benefits are not recognized until the deduction reduces taxes payable. Further, the new guidance allows entities to make an accounting policy election to either estimate forfeitures or recognize forfeitures as they occur. If an election is made, the change to recognize forfeitures as they occur must be adopted using a modified retrospective approach with a cumulative effect adjustment recorded to retained earnings or accumulated deficit. The Company adopted ASU 2016-09 on January 1, 2017. Upon adoption, the Company recorded a deferred tax asset of $0.2 million for previously unrecognized excess tax benefits from stock-based compensation, which was fully offset by an equal increase to its valuation allowance resulting in no impact to opening accumulated deficit. In addition and as provided for under this guidance, the Company made an accounting policy election to recognize forfeitures as they occur. The adoption of this aspect of the guidance did not have a material impact on the Company’s condensed consolidated financial statements. ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory simplifies current accounting treatments by requiring entities to measure most inventories at “the lower of cost and net realizable value” rather than using lower of cost or market. This guidance does not apply to inventories measured using the last-in, first-out method or the retail inventory method. The Company adopted ASU 2015-11 on January 1, 2017. The adoption of this new guidance did not have any impact on the Company’s condensed consolidated financial statements. Accounting Pronouncements Issued But Not Yet Effective ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and subsequent amendments to the initial guidance (collectively, “Topic 606”) will replace all current GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle of Topic 606 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. Topic 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation, among others. This guidance will be effective for the Company beginning January 1, 2018. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective method). The Company plans to adopt this guidance as of January 1, 2018, using the modified retrospective method. The Company currently generates all its revenue from a manufacturing and supply agreement (the “supply agreement”) with Endo International Plc (“Endo”) which the Company expects will be terminated before January 1, 2018. The Company is currently assessing the impact of adopting this guidance on its condensed consolidated financial statements and disclosures, including taking into account the anticipated termination of this supply agreement. The Company will continue to monitor any new contracts it enters into with customers for evaluation under ASU 2014-09. ASU 2016-02, Leases (Topic 842) requires lessees to recognize the lease assets and lease liabilities that arise from both capital and operating leases with lease terms of more than 12 months and to disclose qualitative and quantitative information about lease transactions. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the timing and impact of adopting this new accounting standard on its condensed consolidated financial statements and related disclosures. ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amendments in ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The updated guidance requires a prospective adoption. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the timing and impact of adopting this new accounting standard on its condensed consolidated financial statements and related disclosures.

Summary of Significant Accounting Policies

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates.
