This new standard will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount it expects to receive for those goods and services. This ASU requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and estimates and changes in those estimates. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers: Deferral of the Effective Date" that delayed the effective date of ASU 2014-09 by one year to January 1, 2018, as the Company’s annual reporting period begins after December 15, 2017. In March 2016, the FASB issued ASU 2016-08, "Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net)" which clarifies the implementation guidance on principal versus agent considerations and includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. ASU 2014-09 allows for both retrospective and modified retrospective methods of adoption. The Company is in the process of determining the method of adoption it will elect and is currently assessing the impact of this ASU on its consolidated financial statements and footnote disclosures. In February 2016, the FASB issued ASU No. 2016-02, "Leases," which amends existing guidance to require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. The ASU is effective for the Company January 1, 2019 and interim periods within that reporting period. The ASU requires a modified retrospective method upon adoption. The Company is in the process of assessing the impact of this ASU on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-07, "Investments - Equity Method and Joint Ventures: Simplifying the Transition to the Equity Method of Accounting," which eliminates the requirement to apply the equity method of accounting retrospectively when a reporting entity obtains significant influence over a previously held investment. ASU 2016-07 is effective for the Company January 1, 2017 and interim periods within that reporting period. The adoption of ASU 2016-07 is not expected to have a material effect on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting,” which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company has elected to adopt this accounting standard as of January 1, 2016. The impact of the prospective adoption of the provisions related to the recognition of excess tax benefits in income tax expense was a $2 million income tax benefit during the three months ended April 2, 2016. Additionally, as a result of the adoption of this accounting standard, excess tax benefits on share-based compensation have been reported as a component of operating cash rather than within financing cash flows as previously presented, while the payment of withholding taxes on the settlement of share-based awards has been reported as a component of financing cash flows rather than within operating cash flows as previously presented. The change in presentation of withholding taxes within the condensed consolidated statements of cash flows has been adopted retrospectively, thereby increasing operating cash flows and reducing financing cash flows by $9 million and $5 million for the three months ended April 2, 2016 and April 4, 2015. The presentation of excess tax benefits on share-based compensation has been adjusted prospectively within the condensed consolidated statement of cash flows, increasing operating cash flow and decreasing financing cash flow by $2 million for the three months ended April 2, 2016. In April 2015, the FASB issued ASU No. 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." Under this guidance, debt issuance costs related to a recognized debt liability are required to be presented in the balance sheet as a direct reduction from the carrying amount of such debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this guidance. We have retrospectively adopted ASU 2015-03 effective January 1, 2016. As a result, debt issuance costs which were previously capitalized in other assets in the condensed consolidated balance sheet have been presented as a reduction to long-term debt. As of April 2, 2016 and December 31, 2015, $40 million and $41 million, respectively, have been presented as a component of long-term debt.
