Description of new accounting pronouncements	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to a customer. This guidance will replace most existing revenue recognition guidance and will be effective for the Company beginning in fiscal year 2019, including interim periods within that reporting period, based on the FASB decision in July 2015 (ASU 2015-14, Revenue from Contracts with Customers – Deferral of the Effective Date) to delay the effective date of the new revenue recognition standard by one year, but providing entities a choice to adopt the standard as of the original effective date.

If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. This guidance became effective for the Company beginning in the first quarter of fiscal year 2017.

Description of new accounting pronouncements	In August 2015, the FASB issued ASU 2015-15 which provides additional guidance to ASU 2015-03, which did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. ASU 2015-15 noted that staff of the Securities and Exchange Commission (the SEC) would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. This guidance became effective for the Company beginning in the first quarter of fiscal year 2017 and was applied on a retrospective basis, wherein the condensed consolidated balance sheet of each individual period presented was adjusted to reflect the period-specific effects of applying the new guidance. As a result, the Company reclassed unamortized debt issuance costs related to the Company’s 2020 Notes and the Ex-Im Credit Facility from prepaid expenses and other current assets and from other assets (long-term) to senior notes, net, and other long-term debt, net, respectively, within its consolidated balance sheets as of March 31, 2016. In accordance with ASU 2015-15, the Company has elected to continue to present debt issuance costs related to the Revolving Credit Facility as an asset and subsequently amortize the deferred debt issuance costs over the term of the Revolving Credit Facility arrangement.
