New Accounting Pronouncements or Change in Accounting Principle [Line Items]  
New Accounting Pronouncement or Change in Accounting Principle, Description In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This standard focuses on a targeted improvement to reclassify stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”) enacted on December 22, 2017 from Accumulated other comprehensive income/(loss) to Retained earnings/accumulated deficit. The amount of the reclassification would be the difference between the amount initially charged or credited directly to other comprehensive income at the previously enacted U.S. federal corporate income tax rate that remains in Accumulated other comprehensive income/(loss) and the amount that would have been charged or credited directly to Other comprehensive income/(loss) using the newly enacted U.S. federal corporate income tax rate, excluding the effect of any valuation allowance previously charged to Net income/(loss). ASU 2018-02 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. We are currently evaluating the effect that the new accounting guidance will have on our Consolidated Balance Sheet.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]  
New Accounting Pronouncement or Change in Accounting Principle, Description In February 2016, the FASB issued ASC Topic 842, Leases (Topic 842), a replacement of Leases (Topic 840) and updated by various targeted improvements, which requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets. While many aspects of lessor accounting would remain the same, the new standard makes some changes, such as eliminating today’s real estate-specific guidance. As a globally converged standard, lessees and lessors are required to classify most leases using a principle generally consistent with that of International Accounting Standards. The standard also changes what would be considered the initial direct costs of a lease. The standard would be effective for annual periods beginning after December 15, 2018 and interim periods within that year and must be adopted by a modified retrospective method, with elective reliefs, which requires application of the new guidance for all periods presented, or by an optional transition method, which would allow the application of current legacy guidance, including its disclosure requirements, in the comparative periods presented in the year of adoption. The Company has chosen to use the optional transition method when adopting the new standard and has chosen the package of practical expedients to not reassess whether a contract contains a lease, lease classification and accounting for initial direct costs. We have analyzed the impacts of the new standard on our current accounting policies and internal controls and are in the process of completing our testing and optimization of our third-party leasing software that will manage our lease accounting. With almost two-thirds of our store locations involved in an operating lease, the most significant impact of the new standard will be the recognition of both right-of-use assets (ROU) and lease liabilities of $1.0-$1.4 billion on our balance sheet. Included in the range of ROUs and lease liabilities to be recognized is the operating lease ROU and lease liability related to the required new accounting for the failed sale-leaseback of our Home office. Per the transition guidance of the new standard, the failed sale-leaseback will be considered a valid sale and leaseback that will result in the removal of the related real estate assets and financing obligation, and the recognition of the gain on sale recorded in Retained earnings/(accumulated deficit) and the new operating lease ROU and lease liability in the balance sheet.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]  
New Accounting Pronouncement or Change in Accounting Principle, Description In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB Emerging Issues Task Force) (ASU 2016-15). ASU 2016-15 clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods therein. Entities should apply the guidance retrospectively, but if it is impracticable to do so for an issue, the amendments related to that issue may be applied prospectively. We adopted ASU 2016-15 on February 4, 2018 and it did not have a significant impact on our financial statements and related disclosures.
