Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2: SIGNIFICANT ACCOUNTING POLICIES New Accounting Pronouncements Not Yet Adopted In March 2016, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance on stock compensation which changes how companies account for certain aspects of stock-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. We plan to adopt this guidance in the third quarter of 2016. For the six months ended June 30, 2016, we recognized net tax benefits totaling $3 million as additional paid-in capital on our Unaudited Condensed Consolidated Balance Sheet. Under the new accounting guidance this amount would have instead been recorded to provision for income taxes on our Unaudited Condensed Consolidated Statements of Operations, and will be reclassified in the third quarter of 2016. In addition, the excess tax benefits from stock-based award settlements that are currently reported as cash flows from financing activities on our Unaudited Condensed Consolidated Statement of Cash Flows totaling $6 million for the six months ended June 30, 2016 will instead, be reported as cash flows from operating activities and reclassified in the third quarter of 2016. Finally, we plan to account for forfeitures as they occur rather than continue to estimate expected forfeitures. The net cumulative effect of this change will be recorded to retained earnings upon adoption. The changes described above will be made retroactively as of January 1, 2016. In February 2016, the FASB issued new accounting guidance on leases that is intended to provide enhanced transparency and comparability by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet. The new guidance will continue to classify leases as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. In May 2014, the FASB issued new accounting guidance on revenue from contracts with customers. The new guidance 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 customers. This new guidance also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In March 2016, the FASB issued additional guidance which clarifies principal versus agent considerations and in April 2016, the FASB issued further guidance which clarifies the identification of performance obligations and the implementation guidance for licensing. The updated guidance will replace most existing revenue recognition guidance in GAAP when it becomes effective and permits the use of either a full retrospective approach or a modified retrospective approach, which requires the initial cumulative effect to be recognized at the date of initial application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017 and early adoption is permitted for fiscal years beginning after December 15, 2016. We have not yet selected a transition method and are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. Recently Adopted Accounting Pronouncements In April 2015, the FASB issued new accounting guidance which clarifies the accounting for fees paid by a customer in a cloud computing arrangement. This standard clarified whether a customer should account for a cloud computing arrangement as an acquisition of a software license or as a service arrangement by providing characteristics that a cloud computing arrangement must have in order to be accounted for as a software license acquisition. 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 the arrangement does not include a software license, the customer should account for a cloud computing arrangement as a service contract. The company prospectively adopted this guidance in the first quarter of 2016. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. In September 2015, the FASB issued new accounting guidance which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which they determine the amounts, including the effect on earnings of any amounts that would have been recorded in previous periods if the accounting had been completed at the acquisition date. The Company adopted this guidance in the first quarter of 2016. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. There have been no material changes to our significant accounting policies since December 31, 2015. For additional information about our critical accounting policies and estimates, refer to “Note 2: Significant Accounting Policies”, in the notes to our consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2015.
