New Accounting Pronouncement or Change in Accounting Principle, Description													In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (“Topic 326”). For trade receivables, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. This new standard is effective for the Company’s fiscal year ending January 30, 2021 (‘‘Fiscal 2021’’). The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements, but does not expect the impact to be material.
ASU 2016-02
Revenue, Initial Application Period Cumulative Effect Transition [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description													In March 2016, the FASB issued authoritative guidance which modified existing guidance for off-balance sheet treatment of a lessee’s operating leases (“Topic 842”). The standard requires a lessee to recognize assets and liabilities related to long-term leases that were classified as operating leases under previous guidance. An asset is recognized related to the right to use the underlying asset, and a liability is recognized related to the obligation to make lease payments over the term of the lease. These amounts are determined based on the present value of the lease payments over the lease term. The standard also requires expanded disclosures about leases. The Company adopted this standard as of the beginning of Fiscal 2020, electing the transition option that allowed it not to restate the comparative periods in its financial statements in the year of adoption and to carry forward its historical assessment of whether contracts are, or contain, leases, along with its historical assessment of lease classifications and initial direct costs.
