Recent Adopted and Issued Accounting Pronouncements [Abstract]
Recent Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Guidance In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires that a lessee recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to certain adjustments. The Company adopted ASU 2016-02 during the first quarter of fiscal 2020 using the optional transition method to apply the standard as of the effective date. As a result of adopting this standard, as of February 1, 2019, the Company recognized operating lease liabilities of $384.5 million and corresponding operating lease assets of $341.2 million. In addition, the Company recorded a $9.6 million impairment of the operating lease assets, net of tax, at adoption. The impairment was recorded as a reduction to retained earnings. In June 2018, the FASB issued ASU 2018-07, “FASB Simplifies Guidance on Nonemployee Share-Based Payments,” which supersedes ASC 505-50 and expands the scope of ASC 718 to include all share-based payment arrangements related to the acquisition of goods and services from both nonemployees and employees. As a result, most of the guidance in ASC 718 associated with employee share-based payments, including most of its requirements related to classification and measurement, applies to nonemployee share-based payment arrangements. The Company adopted ASU 2018-07 during the first quarter of fiscal 2020. The adoption did not have an impact on the Company’s condensed consolidated financial statements. 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,” which provides financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate (or portion thereof) in the Tax Cut and Jobs Act is recorded. The Company adopted ASU 2018-02 during the first quarter of fiscal 2020. The adoption did not have an impact on the Company’s condensed consolidated financial statements.
