Basis of Presentation and Summary of Significant Accounting Policies	1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accompanying Condensed Consolidated Financial Statements have been prepared by NCR Corporation (NCR, the Company, we or us) without audit pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC) and, in the opinion of management, include all adjustments (consisting of normal, recurring adjustments, unless otherwise disclosed) necessary for a fair statement of the consolidated results of operations, financial position, and cash flows for each period presented. The consolidated results for the interim periods are not necessarily indicative of results to be expected for the full year. The 2015 year-end Condensed Consolidated Balance Sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States (GAAP). These financial statements should be read in conjunction with NCR’s Form 10-K for the year ended December 31, 2015. Effective January 1, 2016, NCR began management of its business on a solution basis, changing from the previous model of management on a line of business basis, which resulted in a corresponding change to NCR's reportable segments. We have reclassified prior period segment disclosures to conform to the current period presentation. See Note 13, “Segment Information and Concentrations” for additional information. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the period reported. Actual results could differ from those estimates. Evaluation of Subsequent Events The Company evaluated subsequent events through the date that our Condensed Consolidated Financial Statements were issued. No matters were identified that required adjustment of the Condensed Consolidated Financial Statements or additional disclosure. Reclassifications Certain prior-period amounts have been reclassified in the accompanying Condensed Consolidated Financial Statements and Notes thereto in order to conform to the current period presentation. Pending Divestiture As of December 31, 2015, we determined that it was probable that we would dispose of our Interactive Printer Solutions (IPS) business, which triggered an impairment assessment of the related assets which include long-lived assets and goodwill. The assets related to the IPS business were valued using a market approach based on an independent third-party market price. The assessment resulted in charges to reduce the carrying values of goodwill and property, plant and equipment, net. The remaining assets and liabilities of $85 million and $35 million, respectively, remain classified as held for sale as of March 31, 2016 and are included in other current assets and other current liabilities, respectively, in the Condensed Consolidated Balance Sheets. Related Party Transactions In 2011, concurrent with the sale of a noncontrolling interest in our subsidiary, NCR Brasil - Indústria de Equipamentos para Automação S.A., (NCR Manaus) to Scopus Tecnologia Ltda. (Scopus), we entered into a Master Purchase Agreement (MPA) with Banco Bradesco SA (Bradesco), the parent of Scopus. Through the MPA, Bradesco agreed to purchase up to 30,000 ATMs from us over the 5-year term of the agreement. Pricing of the ATMs will adjust over the term of the MPA using certain formulas which are based on prevailing market pricing. We recognized revenue related to Bradesco totaling $18 million during the three months ended March 31, 2016 and 2015, respectively. As of March 31, 2016 and December 31, 2015, we had $13 million and $11 million, respectively, in receivables outstanding from Bradesco. Recent Accounting Pronouncements Issued In May 2014, the FASB issued a new revenue recognition standard that will supersede current revenue recognition guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Subsequently, the FASB issued clarification standards regarding principal versus agent and identifying performance obligations and licensing. The standards will be effective for the first interim period within annual periods beginning after December 15, 2017, with early adoption permitted for annual periods beginning after December 15, 2016, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. The Company is evaluating the impact that adopting this guidance will have on its consolidated financial statements. In February 2016, the FASB issued a new leasing standard that will supersede current guidance related to accounting for leases. The guidance is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The standard will be effective for the first interim period within annual periods beginning after December 15, 2018, with early adoption permitted. The standard is required to be adopted using the modified retrospective approach. The Company is evaluating the impact that adopting this guidance will have on its consolidated financial statements. In March 2016, the FASB issued a new employee share based payment standard that will supersede current guidance related to accounting for stock-based compensation. The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The standard will be effective for the first interim period within annual periods beginning after December 15, 2016, with early adoption permitted. Adoption approach varies based on the amendment topic. The Company is evaluating the impact that adopting this guidance will have on its consolidated financial statements.
