Table of Contents Notes to Consolidated Financial Statements — (Continued) Becton, Dickinson and Company Goodwill and Other Intangible Assets Foreign Currency Translation The Company’s unamortized intangible assets include goodwill which arise from acquisitions. The Company currently reviews goodwill for impairment using quantitative models. Goodwill is reviewed at least annually for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment, referred to as a component. The Company’s reporting units generally represent one level below reporting segments. Potential impairment of goodwill is generally identified by comparing the fair value of a reporting unit, estimated using an income approach, with its carrying value. The annual impairment review performed on July 1, 2019 indicated that all identified reporting units’ fair values exceeded their respective carrying values. Amortized intangible assets include developed technology assets which arise from acquisitions. These assets represent acquired intellectual property that is already technologically feasible upon the acquisition date or acquired in-process research and development assets that are completed subsequent to acquisition. Developed technology assets are generally amortized over periods ranging from 15 to 20 years, using the straight-line method. Customer relationship assets are generally amortized over periods ranging from 10 to 15 years, using the straight-line method. Other intangibles with finite useful lives, which include patents, are amortized over periods principally ranging from one to 40 years, using the straight-line method. Finite-lived intangible assets, including developed technology assets, are periodically reviewed when impairment indicators are present to assess recoverability from future operations using undiscounted cash flows. The carrying values of these finite-lived assets are compared to the undiscounted cash flows they are expected to generate and an impairment loss is recognized in operating results to the extent any finite-lived intangible asset’s carrying value exceeds its calculated fair value. Generally, foreign subsidiaries’ functional currency is the local currency of operations and the net assets of foreign operations are translated into U.S. dollars using current exchange rates. The U.S. dollar results that arise from such translation, as well as exchange gains and losses on intercompany balances of a long-term investment nature, are included in the foreign currency translation adjustments in  Accumulated other comprehensive income (loss). The Company recognizes revenue from product sales when the customer obtains control of the product, which is generally upon shipment or delivery, depending on the delivery terms specified in the sales agreement. Revenues associated with certain instruments and equipment for which installation is complex, and therefore significantly affects the customer’s ability to use and benefit from the product, are recognized upon customer acceptance of these installed products. Revenue for certain service arrangements, including extended warranty and software maintenance contracts, is recognized ratably over the contract term. When arrangements include multiple performance obligations, the total transaction price of the contract is allocated to each performance obligation based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. Variable consideration such as rebates, sales discounts and sales returns are estimated and treated as a reduction of revenue in the same period the related revenue is recognized. These estimates are based on contractual terms, historical practices, and current trends, and are adjusted as new information becomes available. Revenues exclude any taxes that the Company collects from customers and remits to tax authorities. Equipment lease transactions with customers are evaluated and classified as either operating or sales-type leases. Generally, these arrangements are accounted for as operating leases and therefore, revenue is recognized at the contracted rate over the rental period defined within the customer agreement. Additional disclosures regarding the Company's accounting for revenue recognition are provided in Note 6. Revenue Recognition 56
