Recently Issued Accounting Standards	Recently Issued Accounting Standards In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. In adopting ASU 2014-09, companies may use either a full retrospective or a modified retrospective approach. Additionally, this guidance requires improved disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for the first interim period within annual reporting periods beginning after December 15, 2017, and early adoption is permitted but not before the original effective date (for annual reporting periods beginning after December 15, 2016). We are evaluating what impact (if any) ASU 2014-09 will have on our financial position or results of operations. In February 2016, the FASB issued ASU 2016-02 - Leases (ASC 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard 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. 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 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. The ASU is expected to impact our consolidated financial statements as we have certain operating lease arrangements. ASC 842 supersedes the previous leases standard, ASC 840 Leases. The standard is effective on January 1, 2019, with early adoption permitted. We are in the process of evaluating the impact of this new guidance. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which is intended to improve the accounting for share-based payment transactions. Under the new standard, companies can withhold shares up to the maximum individual statutory tax rate in the applicable jurisdiction as participants vest in stock and maintain equity classification of the entire award. Also under the new standard, forfeitures for stock awards may be recorded when they occur (the prior guidance required estimating forfeitures when recording stock compensation costs). Finally, the standard requires classifying cash paid when remitting cash to the tax authorities for stock compensation withholding as financing activity in the statement of cash flows. We adopted this standard effective January 1, 2016. Upon adoption, we revised our policy to account for stock compensation forfeitures as they occur, which resulted in a $185,000 increase in our accumulated deficit for the cumulative effect of change in accounting principle. Also, we will be reclassifying in our statement of cash flows, from operating activities to financing activities, $2.1 million and $3.1 million for the years ended December 31, 2015 and 2014, respectively, for cash paid to taxing authorities for shares withheld.
