Accounting Changes And Error Corrections [Abstract]
New Accounting Standards	Accounting Standards — Recently Adopted: ASU 2016-02 — Leases (Topic 842) The Company adopted ASU 2016-02, “Leases (Topic 842),” and related amendments in the first quarter of fiscal 2020 on a modified retrospective basis. The new standard required lessees to recognize a ROU asset and lease liability for most leases on the balance sheet. The Company elected certain practical expedients permitted under the transition guidance, including the package of practical expedients, which allows the Company to not reassess whether existing contracts contain leases, the lease classification of existing leases, or initial direct costs for existing leases. The Company also elected the transition option that allows entities to only apply the ASU at the adoption date and not apply the provisions to comparative periods; therefore, comparative financial information has not been restated. This transition option allows the recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than the earliest period presented. The Company elected not to separate lease and non-lease components and not to recognize a ROU asset and a lease liability for leases with an initial term of twelve months or less. The Company did not elect the hindsight practical expedient. The Company recognized a cumulative-effect adjustment to increase the opening balance of retained earnings by $1,543,000 as of March 3, 2019, as a result of previous sale leaseback transactions and previous store impairments. The adoption of ASU 2016-02 did not have a material impact on the Company’s consolidated statements of operations or consolidated statements of cash flows for the periods ended November 30, 2019. See Note 2 of the Notes to Consolidated Financial Statements for additional information. ASU 2018-02 — Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-02, “Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” ASU 2018‑02 gives entities the option to reclassify to retained earnings tax effects related to items in accumulated other comprehensive income (“OCI”) that have been stranded in accumulated OCI as a result of the remeasurement of deferred taxes to reflect the lower federal income tax rate enacted as part of the Tax Cuts and Jobs Act of 2017 (“Tax Act”). ASU 2018-02 requires entities to make new disclosures, regardless of whether they elect to reclassify tax effects. The Company adopted the provisions of this guidance in the first quarter of fiscal 2020. The adoption of this guidance did not have a material impact on the Company’s financial statements. An election was made not to reclassify the tax effects of the Tax Act related to items in accumulated OCI. The Company’s policy is to release tax effects related to items in accumulated OCI when an entire portfolio of the type of item is liquidated, sold, or extinguished. Accounting Standards — Pending Adoption: ASU 2016-13 — Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 and related amendments change how entities account for and measure credit losses for most financial assets and certain other instruments. In November 2019, the FASB issued ASU 2019-10, “Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates.” ASU 2019-10 defers the effective date of credit loss standard ASU 2016-13 by two years for smaller reporting companies and permits early adoption. ASU 2016-13 is effective for the Company beginning in fiscal 2024. The Company is evaluating the impact of the adoption of ASU 2016-13 on its financial statements, but does not expect such adoption to have a material impact. ASU 2018-15 — Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In August 2018, the FASB issued ASU 2018-15, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” requiring a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in Accounting Standards Codification 350-40 to determine which implementation costs to capitalize as assets. Capitalized implementation costs related to a hosting arrangement that is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. ASU 2018-15 is effective for the Company beginning in fiscal 2021. The Company is evaluating the impact of the adoption of ASU 2018-15 on its financial statements, but does not expect such adoption to have a material impact. ASU 2019-12 — Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 is effective for the Company beginning in fiscal 2022. The Company is evaluating the impact of the adoption of ASU 2019-12 on its financial statements, but does not expect such adoption to have a material impact.
