Basis of Presentation	1. Basis of Presentation The Company American Express Credit Corporation (Credco), together with its subsidiaries, is a wholly owned subsidiary of American Express Travel Related Services Company, Inc. (TRS), which is a wholly owned subsidiary of American Express Company (American Express). Credco is engaged in the business of financing non-interest-earning Card Member receivables arising from the use of American Express charge cards issued in the United States and in certain countries outside the United States. Credco also finances certain interest-earning revolving loans generated by Card Member spending on American Express credit cards issued in non-U.S. markets, although interest-earning revolving loans are primarily funded by subsidiaries of TRS other than Credco. Credco executes material transactions with its affiliates. The agreements between Credco and its affiliates provide that the parties intend that the transactions thereunder be conducted on an arm’s length basis; however, there can be no assurance that the terms of these arrangements are the same as would be negotiated between independent, unrelated parties. American Express provides Credco with financial support with respect to maintenance of its minimum overall 1.25 fixed charge coverage ratio, which is achieved by charging appropriate discount rates on the purchases of receivables Credco makes from, and the interest rates on the loans Credco provides to, TRS and other American Express subsidiaries. Each monthly period, the discount and interest rates are determined to generate income for Credco that is sufficient to maintain its minimum fixed charge coverage ratio. The revenue earned by Credco from purchasing Card Member receivables and loans at a discount is reported as discount revenue on the Consolidated Statements of Income and Retained Earnings. The accompanying Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in Credco’s Annual Report on Form 10-K for the year ended December 31, 2017 (Form 10-K). If not materially different, certain footnote disclosures included therein have been omitted from this Quarterly Report on Form 10-Q. The interim consolidated financial information in this report has not been audited. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim period consolidated financial information, have been made. Results of operations reported for interim periods are not necessarily indicative of results for the entire year. The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These accounting estimates reflect the best judgment of management, but actual results could differ. Recently Issued Accounting Standards In June 2016, the Financial Accounting Standards Board (FASB) issued new accounting guidance for recognition of credit losses on financial instruments, effective January 1, 2020, with early adoption permitted on January 1, 2019. The guidance introduces a new credit reserving model known as the Current Expected Credit Loss (CECL) model, which is based on expected losses, and differs significantly from the incurred loss approach used today. The CECL model requires measurement of expected credit losses not only based on historical experience and current conditions, but also by including reasonable and supportable forecasts incorporating forward-looking information. The guidance also requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption. Credco does not intend to adopt the new standard early and is currently evaluating the impact the new guidance will have on its financial position, results of operations and cash flows; however, it is expected that the CECL model will alter the assumptions used in estimating credit losses on Card Member receivables and loans, and may result in material increases to Credco’s credit reserves as the new guidance involves earlier recognition of expected losses for the life of the assets. American Express has established an enterprise-wide, cross-discipline governance structure to implement the new standard, and continue to identify and conclude on key interpretive issues along with evaluating American Express’ existing credit loss forecasting models and processes in relation to the new guidance to determine what modifications may be required. In February 2018, as a result of the enactment of the Tax Cuts and Jobs Act (the Tax Act), the FASB issued new accounting guidance on the reclassification of certain tax effects from accumulated other comprehensive income (loss) (AOCI) to retained earnings. The optional guidance is effective January 1, 2019, with early adoption permitted. Credco is evaluating whether it will adopt the new guidance along with any impacts on Credco’s financial position, results of operations and cash flows, none of which are expected to be material. Recently Adopted Accounting Standards In January 2016, the FASB issued new accounting guidance on the recognition and measurement of financial assets and financial liabilities, which was effective and adopted by Credco as of January 1, 2018. The guidance makes targeted changes to GAAP; specifically to the classification and measurement of equity securities, and to certain disclosure requirements associated with the fair value of financial assets and liabilities. The adoption of the guidance did not have a material impact on Credco’s financial position, results of operations and cash flows. Credco implemented changes to its accounting policies, business processes and internal controls in support of the new guidance. Such changes were not material. In November 2016, the FASB issued new accounting guidance on the cash flow classification and presentation of changes in restricted cash or restricted cash equivalents, effective January 1, 2018. The guidance provides specifically that amounts generally described as restricted cash and restricted cash equivalents are to be included with cash and cash equivalents on the statement of cash flows. Credco holds a restricted cash balance such that it becomes a material change to the way balances are presented on the statement of cash flows. Beginning with the quarter ended March 31, 2018, Credco’s consolidated statements of cash flows reflect the adoption of the standard using the full retrospective method, which applies the new standard to each prior reporting period presented. In August 2017, the FASB issued new accounting guidance providing targeted improvements to the accounting for hedging activities, effective January 1, 2019, with early adoption permitted in any interim period or fiscal year before the effective date. The guidance introduces a number of amendments, several of which are optional, that are designed to simplify the application of hedge accounting, improve financial statement transparency and more closely align hedge accounting with an entity’s risk management strategies. Effective January 1, 2018, Credco adopted the guidance with no material impact on its financial position, results of operations and cash flows, along with associated changes to its accounting policies, business processes and internal controls in support of the new guidance. Such changes were not material.
