New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards Implementation Costs in Cloud Computing Arrangements In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract" ("ASU 2018-15"). ASU 2018-15 addresses diversity in practice surrounding the accounting for costs incurred to implement a cloud computing hosting arrangement that is a service contract by establishing a model for capitalizing or expensing such costs, depending on their nature and the stage of the implementation project during which they are incurred. Any capitalized costs are to be amortized over the reasonably certain term of the hosting arrangement and presented in the same line within the statement of operations as the related service arrangement's fees. ASU 2018-15 also requires enhanced qualitative and quantitative disclosures surrounding hosting arrangements that are service contracts. ASU 2018-15 is effective for the Company beginning in its fiscal year ending March 27, 2021 ("Fiscal 2021"), with early adoption permitted, and may be adopted on either a retrospective or prospective basis. Although the impact of adopting ASU 2018-15 will depend on the composition of its cloud computing arrangements in place at that time, other than the new disclosure requirements, the Company does not currently expect that it will have a material impact on its consolidated financial statements. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ("ASU 2018-02"). Existing accounting guidance requires the remeasurement of deferred tax assets and liabilities resulting from a change in tax laws and rates to be presented within net income, including deferred taxes related to items recorded within AOCI. ASU 2018-02 provides an entity with the option to adjust AOCI for the "stranded" tax effect of such remeasurements resulting from the reduction in the U.S. federal statutory income tax rate under the 2017 Tax Cuts and Jobs Act (the "TCJA") through a reclassification to retained earnings. The Company adopted ASU 2018-02 as of the beginning of the first quarter of Fiscal 2020 and elected to reclassify the income tax effect stranded in AOCI related to the TCJA, inclusive of state income tax-related effects, resulting in a $4.9 million increase to its opening retained earnings balance. The Company generally releases income tax effects from AOCI when the corresponding pretax AOCI items are reclassified to earnings. Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"). ASU 2016-13, which was further updated and clarified by the FASB through issuance of additional related ASUs, amends the guidance surrounding measurement and recognition of credit losses on financial assets measured at amortized cost, including trade receivables and investments in debt securities, by requiring recognition of an allowance for credit losses expected to be incurred over an asset's lifetime based on relevant information about past events, current conditions, and supportable forecasts impacting its ultimate collectibility. This "expected loss" model will result in earlier recognition of credit losses than the current "as incurred" model, under which losses are recognized only upon an occurrence of an event that gives rise to the incurrence of a probable loss. ASU 2016-13 is effective for the Company beginning in its Fiscal 2021, with early adoption permitted, and is to be adopted on a modified retrospective basis. The Company is currently evaluating the impact that ASU 2016-13 will have on its consolidated financial statements, if any. Leases In February 2016, the FASB issued ASU No. 2016-02, "Leases." ASU No. 2016-02, along with certain other ASUs that were subsequently issued to clarify and modify certain of its provisions (collectively "ASU 2016-02"), supersedes historical lease accounting guidance and requires that, among its provisions, a lessee's rights and fixed payment obligations under most leases be recognized as ROU assets and lease liabilities on its balance sheet, initially measured based on the present value of its fixed payment obligations over the lease term. Under historical guidance, only those leases classified as capital were recognized on a lessee's balance sheet; operating leases were not recognized on the balance sheet. ASU 2016-02 retains a dual model for classifying leases as either finance (formerly referred to as "capital") or operating, consistent with historical guidance, which governs the pattern of expense recognition reflected in the statement of operations over the lease term. Accordingly, recognition of lease expense in the statement of operations will not significantly change. Additionally, variable lease payments based on performance, such as percentage-of-sales-based payments, are not included in the measurement of ROU assets and lease liabilities and, consistent with historical practice, are recognized as an expense in the period incurred. The standard also requires enhanced quantitative and qualitative lease-related disclosures. The Company adopted ASU 2016-02 as of the beginning of the first quarter of Fiscal 2020 using a modified retrospective approach under which the cumulative effect of initially applying the standard was recognized as an adjustment to its opening retained earnings (discussed further below), with no restatement of prior year amounts. In connection therewith, the Company applied an optional package of practical expedients intended to ease transition to the standard for existing leases by, among its provisions, carrying forward its original lease classification conclusions without reassessment. Upon adoption of ASU 2016-02, the Company recognized initial ROU asset and lease liability balances of approximately $1.60 billion and $1.75 billion, respectively, on its consolidated balance sheet. Additionally, in connection with its adoption of ASU 2016-02, the Company recorded an adjustment to reduce its opening retained earnings balance by $131.6 million, net of related income tax benefits, reflecting the impairment of an ROU asset for a certain real estate lease of which, under historical accounting guidance, the Company was previously deemed the owner for accounting purposes (commonly referred to as a "build-to-suit" lease arrangement). Specifically, although the Company no longer generates revenue or other cash flows from its rights underlying the leased asset given it no longer actively uses the space for commercial purposes, the asset was previously not considered impaired under historical accounting guidance as its fair value, assessed from an ownership perspective (and not from that of a lessee), exceeded its carrying value. However, in accordance with and upon transitioning to ASU 2016-02, the Company derecognized the remaining asset and liability balances previously recognized solely as a result of the arrangement's build-to-suit designation, as the related construction activities that originally gave rise to such designation have since ended, and established initial ROU asset and lease liability balances measured based on the Company's remaining fixed payment obligations under the lease. The initial ROU asset was then assessed for impairment based on the aggregate estimated cash flows that could be generated by transferring the lease to a market participant sublessee for the remainder of its term, which were lower than the aggregate remaining lease payments underlying the measurement of the initial ROU asset. Accordingly, the Company impaired the initial ROU asset by $175.4 million to its estimated fair value which was recorded as a reduction to its opening retained earnings balance, net of related income tax benefits of $43.8 million, upon adoption of ASU 2016-02, as previously noted. The Company also recorded other initial ROU asset impairment adjustments to reduce its opening retained earnings balance upon adoption of the standard related to leases of certain underperforming retail locations for which the carrying value of the respective store's initial operating lease ROU asset exceeded its fair value. These impairments of $49.7 million were recorded as adjustments to reduce the Company's opening retained earnings balance by $37.8 million, net of related income tax effects. Leasehold improvements related to these underperforming retail locations were previously fully-impaired prior to the adoption of ASU 2016-02. See Notes 3 and 13 for further discussion of the Company's lease accounting policy and other related disclosures.
