New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Note 9 – Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” related to revenue recognition. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects to be entitled to in exchange for the goods or services. The standard also requires more detailed disclosures and provides additional guidance for transactions that were not addressed completely in prior accounting guidance. ASU 2014-09 provides alternative methods of initial adoption and was to be effective for fiscal years beginning after December 15, 2016, and interim periods within those annual periods. Early adoption was not permitted. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers: Deferral of the Effective Date”. The amendment in this ASU defers the effective date of ASU No. 2014-09 for all entities for one year. In March, April and May 2016, the FASB issued ASU No. 2016-08, ASU No. 2016-10 and ASU No. 2016-12, respectively, which clarify implementation guidance, including the guidance on principal versus agent considerations, performance obligations and licensing and assessments of collectability and noncash considerations. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to fiscal years beginning after December 15, 2017, including interim reporting periods within that fiscal year. The Company adopted the new revenue recognition standard as of January 1, 2018 using the modified retrospective method, which requires the cumulative effect of adoption, if any, to be recognized as an adjustment to opening accumulated deficit in the period of adoption. The majority of the Company’s revenue relates to the sale of finished products to various customers, and the adoption did not have any impact on revenue recognized from these transactions. The Company completed its analysis of the impact on certain less significant transactions involving third-party arrangements, and as a result of the analysis, the Company accelerated the remaining approximately $278,000 of deferred revenue to be recognized under the Bellco license agreement as of December 31, 2017 and recorded a cumulative effect adjustment to opening accumulated deficit as of January 1, 2018. In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” that modifies certain aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The accounting standard update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption was permitted. The Company adopted this guidance as of January 1, 2018 and the guidance did not have an impact on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows in order to reduce diversity in practice. The guidance was effective for the Company beginning in the first quarter of fiscal year 2018. Early adoption was permitted. The Company adopted the guidance as of January 1, 2018 and the guidance did not have a significant impact on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, “Restricted Cash,” which clarifies how restricted cash is presented and classified in the statement of cash flows. The guidance was effective for the Company beginning in the first quarter of fiscal year 2018. Early adoption was permitted. The Company adopted the guidance as of January 1, 2018 and the guidance did not have an impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, “Clarifying the Definition of a Business,” which clarifies the definition of a business in a business combination. The guidance was effective for the Company beginning in the first quarter of fiscal year 2018. Early adoption was permitted. The Company adopted the guidance as of January 1, 2018 and the guidance did not have an impact on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, “Compensation – Stock Compensation” which requires modification accounting to be used on shared-based payment awards if the fair value, the vesting conditions, or the classification of the award changes as a result of the change in terms or conditions. The guidance was effective for the Company beginning in the first quarter of fiscal year 2018. The Company adopted the guidance as of January 1, 2018 and the guidance did not have an impact on its consolidated financial statements. Recent Accounting Pronouncements, Not Yet Effective In February 2016, the FASB issued ASU No. 2016-02, “Leases,” that discusses how an entity should account for lease assets and lease liabilities. The guidance specifies that an entity who is a lessee under lease agreements should recognize lease assets and lease liabilities for those leases classified as operating leases under previous FASB guidance. Accounting for leases by lessors is largely unchanged under the new guidance. The guidance is effective for the Company beginning in the first quarter of 2019. Early adoption is permitted. 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. The Company is assessing the impact of adopting this guidance on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance is effective for the Company beginning in the first quarter of fiscal year 2020. Early adoption is permitted beginning in the first quarter of fiscal year 2019. The Company is assessing the impact of adopting this guidance on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” which simplifies the test for goodwill impairment. The guidance is effective for the Company beginning in the first quarter of fiscal year 2020. Early adoption is permitted for interim or annual goodwill impairments tests after January 1, 2017. The Company is assessing the impact of adopting this guidance on its consolidated financial statements.
