Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09) to provide guidance on revenue recognition. ASU 2014-09 requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance. These may include 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. In August 2015, the FASB issued Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers (ASU 2015-14) to defer the effective date for ASU 2014-09 to the first quarter of 2018 for public companies. Early adoption up to the first quarter of 2017 is permitted. Upon adoption, ASU 2014-09 can be applied retrospectively to all periods presented or only to the most current period presented with the cumulative effect of changes reflected in the opening balance of retained earnings in the most current period presented. The Company is currently evaluating the method of adoption and the impact of adopting ASU 2014-09 on its consolidated financial statements. In May 2015, the FASB issued Accounting Standards Update No. 2015-03, Interest - Imputation of Interest (ASU 2015-03) to provide guidance on the presentation of debt issuance costs. ASU 2015-03 requires a company to present debt issuance costs as a reduction from the carrying amount of the financial liability and not recorded as separate assets. ASU 2015-03 is effective for the Company in the first quarter of 2016. Early adoption is permitted. Upon adoption, ASU 2015-03 should be applied retrospectively to all periods presented. The Company's adoption of ASU 2015-03 would have resulted in a decrease in Other long-term assets, Convertible notes, and Term loan—long-term portion of $2.8 million as of September 30, 2015. In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Inventory (ASU 2015-11) to provide guidance on simplifying the measurement of inventory. ASU 2015-11 requires a company to measure inventory at the lower of cost and net realizable value. ASU 2015-11 is effective for the Company in the first quarter of 2017. Early adoption is permitted. Upon adoption, ASU 201511 should be applied prospectively. The Company is currently evaluating the method of adoption and the impact of adopting ASU 2015-11 on its consolidated financial statements.
