Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Accounting Standards Adopted in Fiscal 2020 Accounting Standards Codification (“ASC”) 842 — Leases (“ASC 842”) In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (“ASU 2016-02”), which requires lessees to include most leases on the balance sheet as lease liabilities with an associated right-of-use ("ROU") asset. Since the issuance of ASU 2016-02, the FASB released several amendments to improve and clarify the implementation guidance, as well as to change the allowable adoption methods. These standards have been collectively codified within ASC 842, Leases (“ASC 842”). We adopted ASC 842 using the modified retrospective method and applied the standard to all leases existing as of September 1, 2019. Information for prior years presented has not been restated and continues to reflect the authoritative accounting standards in effect for those periods. We elected the package of transition practical expedients that allows us to carryforward our historical assessments of whether existing contracts contain leases, determinations of lease classification, and treatments of initial direct costs. As of September 1, 2019, we recognized total operating lease liabilities of $64.7 million in our Consolidated Balance Sheets, of which $49.3 million was recorded within Long-term operating lease liabilities and $15.4 million was recorded within Current operating lease liabilities. We additionally derecognized $5.1 million of previously recorded net deferred rent balances and recorded ROU assets of $59.6 million related to our operating leases, which were reflected within Operating lease right-of-use assets in our Consolidated Balance Sheets. Accounting Standards Yet to Be Adopted In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. ASU 2019-12 is effective for fiscal years beginning after December 15, 2021. Most amendments within the standard are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. We are currently evaluating the impacts of the the provisions of ASU 2019-12 on our financial condition, results of operations, and cash flows. In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (“ASU 2018-15”), which will require customers to apply internal-use software guidance to determine the implementation costs that are able to be capitalized. Capitalized implementation costs will be required to be amortized over the term of the arrangement, beginning when the cloud computing arrangement is ready for its intended use. ASU 2018-15 is effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2019. The standard allows changes to be applied either retrospectively or prospectively. We will adopt the standard as required in fiscal 2021. The provisions of ASU 2018-15 are not expected to have a material effect on our financial condition, results of operations, or cash flows. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires an entity to assess impairment of its financial instruments based on its estimate of expected credit losses. Since the issuance of ASU 2016-13, the FASB released several amendments to improve and clarify the implementation guidance. The provisions of ASU 2016-13 and the related amendments are effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2019. Entities are required to apply these changes through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We will adopt the amendments as required in fiscal 2021. The provisions of ASU 2016-13 are not expected to have a material effect on our financial condition, results of operations, or cash flows. All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable.
