DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Bel Fuse Inc. and subsidiaries ("Bel," the "Company," "we," "us," and "our") design, manufacture and sell a broad array of products that power, protect and connect electronic circuits. These products are used in the networking, telecommunication, high-speed data transmission, commercial aerospace, military, e-Mobility, broadcasting, transportation and consumer electronic industries around the world. We manage our operations by product group through our reportable operating segments, Connectivity Solutions, Power Solutions and Protection and Magnetic Solutions, in addition to a Corporate segment.

We amortize finite-lived identifiable intangible assets over the shorter of their stated or statutory duration or their estimated useful lives, ranging from 1 to 16 years, on a straight-line basis to their estimated residual values and periodically review them for impairment. Total identifiable intangible assets comprise 11.9% and 14.5% at December 31, 2021 2020 We use the acquisition method of accounting for all business combinations and do not fourth Impairment and Disposal of Long-Lived Assets For indefinite-lived intangible assets, such as trademarks and trade names, each year and whenever impairment indicators are present, we determine the fair value of the asset and record an impairment loss for the excess of book value over the fair value, if any. In addition, in all cases of an impairment review we re-evaluate whether continuing to characterize the asset as indefinite-lived is appropriate. See Note 4, Depreciation ro m 1 to 33 years for buildings and leasehold improvements, and from 2 to 14 years for ma Derivative Financial Instruments not The Company records all derivatives as assets or liabilities on our consolidated balance sheets at their fair values. Gains and losses from the changes in values of these derivatives are accounted for based on the use of the derivative and whether it qualifies for hedge accounting. The counterparties to our derivative financial instruments consist of several major international financial institutions. We regularly monitor the financial strength of these institutions. While the counterparties to these contracts expose us to credit-related losses in the event of a counterparty’s non-performance, the risk would be limited to the unrealized gains on such affected contracts.
