Under US GAAP, inventory-related disclosures are similar to those under IFRS, with key differences. Specifically, US GAAP requires disclosure of the carrying amount of inventories measured at fair value less costs to sell (Option A). However, US GAAP does not permit the reversal of prior-year inventory write-downs, making disclosures related to such reversals (Options B and C) irrelevant under US GAAP. This distinction is critical for analysts evaluating inventory disclosures and understanding the financial reporting framework applicable to a company.
