Table of Contents Notes to Consolidated Financial Statements — (Continued) Becton, Dickinson and Company 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 18. 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 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. 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. Amounts presented in the Company's financial statements for the prior-year periods were not revised and are reflective of the revenue recognition requirements which were in effect for those periods. 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 income, net  on its consolidated income statements for all periods presented. Revisions of prior-year amounts were estimated based upon previously disclosed amounts. 60
