New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Guidance	New Accounting Guidance Changes in Accounting Policies In February 2016, the FASB issued a comprehensive new lease standard which superseded previous lease guidance. The standard requires a lessee to recognize an asset related to the right to use the underlying asset and a liability that approximates the present value of the lease payments over the term of contracts that qualify as leases under the new guidance. The standard also requires expanded disclosures surrounding leases. The Company adopted this guidance as of February 3, 2019 using the modified retrospective approach and recorded a cumulative adjustment to increase retained earnings by approximately $0.3 million, net of taxes, with no restatement of prior periods. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allows the Company to carry forward historical lease classification. As of the adoption date, the Company recorded operating lease ROU assets and operating lease liabilities of approximately $1.0 billion. The standard did not materially impact the Company’s consolidated statements of income or cash flows. Refer to Note 9 for the Company’s expanded disclosures on leases. In August 2017, the FASB issued authoritative guidance to better align the results of hedge accounting with an entity’s risk management activities. This guidance eliminated the requirement to separately measure and report ineffectiveness for instruments that qualify for hedge accounting and generally requires that the entire change in the fair value of such instruments ultimately be presented in the same line as the respective hedge item. As a result, there is no interest component recognized for the ineffective portion of instruments that qualify for hedge accounting, but rather all changes in the fair value of such instruments are included in other comprehensive income (loss). The guidance also reduced the overall complexity of the hedge accounting model, including broadening the scope of risks eligible to qualify for hedge accounting, easing documentation and effectiveness assessment requirements, modifying the treatment of components excluded from the assessment of hedge effectiveness and updating disclosure requirements. In October 2018, the FASB clarified the new hedge accounting guidance by allowing the Secured Overnight Financing Rate (“SOFR”) to be eligible as a U.S. benchmark interest rate for purposes of applying hedge accounting. The Company adopted this guidance as of February 3, 2019. The adoption of this guidance resulted in a decrease in retained earnings and a decrease in accumulated other comprehensive loss of approximately $2.0 million. Approximately $1.5 million of this gain was recognized in cost of product sales during fiscal 2020, on a pre-tax basis. In January 2017, the FASB issued authoritative guidance to simplify the testing for goodwill impairment by removing step two from the goodwill testing. Under prior guidance, if the fair value of a reporting unit was lower than its carrying amount (step one), an entity would have calculated an impairment charge by comparing the implied fair value of goodwill with its carrying amount (step two). The implied fair value of goodwill was calculated by deducting the fair value of the assets and liabilities of the respective reporting unit from the reporting unit’s fair value as determined under step one. This guidance instead provides that an impairment charge should be recognized based on the difference between a reporting unit’s fair value and its carrying value. This guidance also does not require a qualitative test to be performed on reporting units with zero or negative carrying amounts. However, entities need to disclose any reporting units with zero or negative carrying amounts that have goodwill and the amount of goodwill allocated to each. The Company early adopted this guidance during the fourth quarter of fiscal 2020. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or related disclosures. Recently Issued Accounting Guidance In June 2016, the FASB issued authoritative guidance related to the measurement of credit losses on financial instruments. This guidance replaces the current “as incurred” loss model with an “expected loss” model which requires the recognition of an allowance for credit losses expected to be incurred over an asset’s lifetime. The measurement of expected credit losses is based on relevant information about past events, current conditions and reasonable and supportable forecasts impacting the collectibility of the reported amounts. This guidance is effective for fiscal years beginning after December 15, 2019, which will be the Company’s first quarter of fiscal 2021. The standard will require entities to record a cumulative-effect adjustment to the balance sheet as of the beginning of the first reporting period in which the guidance is effective. The Company does not expect that the adoption of this guidance will have a material impact on the Company’s consolidated financial statements other than requiring enhanced disclosures. In August 2018, the FASB issued authoritative guidance to modify the disclosure requirements on fair value measurements. This guidance is effective for fiscal years beginning after December 15, 2019, which will be the Company’s first quarter of fiscal 2021 with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s related disclosures. In August 2018, the FASB issued authoritative guidance to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This guidance is effective for fiscal years beginning after December 15, 2020, which will be the Company’s first quarter of fiscal 2022, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard on its related disclosures. In August 2018, the FASB issued authoritative guidance to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The guidance provides criteria for determining which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The capitalized implementation costs are required to be expensed over the term of the hosting arrangement. The guidance also clarifies the presentation requirements for reporting such costs in the entity’s financial statements. This guidance is effective for fiscal years beginning after December 15, 2019, which will be the Company’s first quarter of fiscal 2021, with early adoption permitted. The Company plans to adopt this guidance on a prospective basis and does not expect the adoption of this guidance to have a material impact on the Company’s consolidated financial statements other than requiring a different classification of certain implementation costs within the Company’s consolidated financial statements as well as enhanced disclosures. In December 2019, the FASB issued authoritative guidance that simplifies the accounting for income taxes by eliminating certain exceptions to general principles related to intraperiod tax allocations, ownership changes in foreign investments and calculating income taxes in an interim period when year-to-date losses exceed total anticipated losses. The new guidance also simplifies the accounting for income taxes related to franchise taxes that are partially based on income, the step up in the tax basis of goodwill, allocation of current and deferred tax expense for certain legal entities and enacted changes in tax laws or rates during interim periods, among other improvements. This guidance is effective for fiscal years beginning after December 15, 2020, which will be the Company’s first quarter of fiscal 2022, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures. In March 2020, the FASB issued authoritative guidance to provide temporary optional expedients and exceptions related to contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates, such as SOFR. This guidance may be adopted as of March 12, 2020 through December 31, 2022. This temporary relief cannot be applied to contract modifications after December 31, 2022. The Company is currently evaluating its election options and the impact on its consolidated financial statements and related disclosures.
