New Accounting Pronouncement or Change in Accounting Principle, Description	In March 2016, the Financial Accounting Standards Board (“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 its fiscal year ending February 1, 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.
