Subject 3. Inventory method changes

Consistency of inventory costing is required under both IFRS and U.S. GAAP. If a company changes an accounting policy, the change must be justifiable and applied retrospectively to the financial statements. An exception to the retrospective restatement is when a company reporting under U.S. GAAP changes to the LIFO method.
