 of comprehensive loss in the stockholders’ equity until realized. Realized gains and losses on sales of marketable securities, if any, are determined on the specific identification method and are reclassified from accumulated other comprehensive loss to results of operations as “Other expense, net.” Realized gains and losses were not significant for the years ended December 31, 2024 and 2023, respectively.For the Company’s available-for-sale debt securities in an unrealized loss position, the Company determines whether a credit loss exists. In this assessment, among other factors, the Company considers the extent to which the fair value is less than the amortized cost, any changes to the rating of the security by a rating agency and adverse conditions specifically related to the security.

Actual collection losses may differ from management’s estimates, and such differences could be material to the Company’s financial position and results of operations.Inventory Valuation and Supplier Purchase CommitmentsInventory, which primarily consists of finished goods purchased from CMs or ODMs, is stated at the lower of cost (determined by the first-in, first-out method) and net realizable value. Inbound shipping costs and tariffs are included in the cost of inventory. In addition, from time to time, the Company procures component inventory primarily as a result of manufacturing discontinuation of critical components by suppliers or a change in suppliers.
