Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The Company’s significant accounting policies are described in Note 2 to its audited consolidated financial statements for the year ended December 31, 2016, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC on March 30, 2017. Except as discussed below, these accounting policies have not significantly changed during the three months ended March 31, 2017. Warrant Accounting As more fully described in Note 10, the Company issued warrants to purchase shares of the Company’s common stock in connection with a private placement transaction that closed on March 29, 2017. These warrants contain a feature that could require the transfer of cash in the event of a Fundamental Transaction, as defined in such warrants (other than a Fundamental Transaction not approved by the Company’s Board of Directors). The warrant holders do not control the Company’s Board of Directors, and therefore, since potential future cash settlement is deemed to be within the Company’s control, the warrants are classified in stockholder’s equity in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity. Recent Accounting Pronouncements In May 2014, the FASB issued new accounting guidance related to revenue recognition. This new standard replaces all current U.S. GAAP guidance on this topic and eliminates all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. This guidance, including all subsequent clarifications, is effective for the Company for annual and interim reporting periods in fiscal years beginning after December 15, 2017 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company performed a preliminary assessment of the impact of the new standard on the consolidated financial statements, and considered all items outlined in the standard. In assessing the impact, the Company has outlined all revenue generating activities, mapped those activities to performance obligations and traced those performance obligations to the standard. The Company is now assessing what impact the change in standard will have on those performance obligations. The Company will continue to evaluate the future impact and method of adoption of the new standard and related amendments on the consolidated financial statements and related disclosures throughout 2017. The Company will adopt the new standard beginning January 1, 2018. In July 2015, the FASB issued new accounting guidance, which changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value for entities that do not measure inventory using the last-in, first-out or retail inventory method. The guidance also eliminates the requirement for these entities to consider replacement cost or net realizable value less an approximately normal profit margin when measuring inventory. The guidance is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company adopted the standard for reporting periods beginning January 1, 2017. In February 2016, the FASB issued new accounting guidance, which changes several aspects of the accounting for leases, including the requirement that all leases with durations greater than twelve months be recognized on the balance sheet. The guidance is effective for annual periods and interim periods in fiscal years beginning after December 15, 2018. The Company is evaluating the impact of adopting this new accounting standard on its financial statements. In March 2016, the FASB issued new accounting guidance, which changes several aspects of the accounting for share-based payment award transactions, including accounting and cash flow classification for excess tax benefits and deficiencies, forfeitures, and tax withholding requirements and cash flow classification. The guidance is effective for annual periods and interim periods in fiscal years beginning after December 15, 2016. The Company adopted the standard for reporting periods beginning January 1, 2017. In August 2016, the FASB issued new accounting guidance, which eliminates the diversity in practice related to the classification of certain cash receipts and payments in the statement of cash flows, by adding or clarifying guidance on eight specific cash flow issues. The guidance is effective for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted. The amendments in this update should be applied retrospectively to all periods presented, unless deemed impracticable, in which case, prospective application is permitted. The Company is currently evaluating the new guidance and has not determined the impact this standards update may have on its financial statements.
