Accounting Standards Update and Change in Accounting Principle

Accounting Changes

New Accounting Principles Adopted

In June 2016, the Financial Accounting Standards Board ("FASB") issued a new accounting standard which requires earlier recognition of credit losses on loans and other financial instruments held by entities, including trade receivables. The new standard requires entities to measure all expected credit losses for financial assets held at each reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The Company’s adoption of this accounting standard on October 1, 2020, using the modified retrospective method, did not have a material impact on the Company's consolidated financial statements.

On October 1, 2020, the Company retrospectively adopted an accounting standard update which added, removed and clarified disclosure requirements relating to defined benefit plans and other postretirement plans. The Company’s adoption of this update on October 1, 2020 did not materially impact its disclosures. See Note 9 for the Company’s defined pension plan and other benefit plan disclosures.

In July 2018, the FASB issued accounting standard update (“ASU”) ASU 2018-09, "Codification Improvements", which, among other items, amended an illustrative example of a fair value hierarchy disclosure to indicate that a certain type of investment should not always be considered to be eligible to use the net asset value ("NAV") per share practical expedient. Also, it further clarified that an entity should evaluate whether a readily determinable fair value exists or whether its investments qualify for the NAV practical expedient. The Company early adopted this standard in the fourth quarter of fiscal year 2020 on a prospective basis, which is reflected in the fair value hierarchy classification of pension assets in Note 9, but does not change the fair value measurements of the investments.

In August 2018, the FASB issued a new accounting standard 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 Company early adopted this standard as of April 1, 2020 on a prospective basis. The adoption of this standard did not materially impact the Company's consolidated financial statements.

In February 2016, the FASB issued a new lease accounting standard which requires lessees to recognize lease assets and lease liabilities on the balance sheet, as well as expanded disclosures regarding leasing arrangements. The Company adopted this standard on October 1, 2019, and elected certain practical expedients permitted under the transition guidance, including a transition method which allows application of the new standard at its adoption date, rather than at the earliest comparative period presented in the financial statements. The Company also elected not to perform any reassessments relative to its expired and existing leases upon its adoption of the new requirements. The Company's adoption of this standard did not materially impact its consolidated financial statements. Additional disclosures regarding the Company’s lease arrangements are provided in Note 17.

On October 1, 2018, the Company adopted Accounting Standards Codification Topic 606, "Revenue from Contracts with Customers" ("ASC 606") using the modified retrospective method. Under ASC 606, revenue is recognized upon the transfer of control of goods or services to customers and reflects the amount of consideration to which a reporting entity expects to be entitled in exchange for those goods or services. The Company assessed the impact of this new standard on its consolidated financial statements based upon a review of contracts that were not completed as of October 1, 2018. This accounting standard adoption, which is further discussed in Note 6, did not materially impact any line items of the Company's consolidated income statements and balance sheet.

On October 1, 2018, the Company retrospectively adopted an accounting standard update which requires all components of net periodic pension and postretirement benefit costs to be disaggregated from the service cost component and to be presented on the income statement outside a subtotal of income from operations, if one is presented. Upon the Company's adoption of the accounting standard update, which did not have a material impact on its consolidated financial statements, all components of the Company’s net periodic pension and postretirement benefit costs, aside from service cost, are recorded to Other (expense) income, net on its consolidated income statements for all periods presented.

On October 1, 2018, the Company adopted an accounting standard update which requires that the income tax effects of intercompany sales or transfers of assets, except those involving inventory, be recognized in the income statement as income tax expense (or benefit) in the period that the sale or transfer occurs. The Company adopted this accounting standard update, which did not have a material impact on its consolidated financial statements, using the modified retrospective method.
