ASC 330, Inventory, and IAS 2, Inventories, are based on the principle that the primary basis of accounting for inventory is cost. Both define inventory as assets held for sale in the ordinary course of business, in the process of production for such sale or to be consumed in the production of goods or services. Permissible techniques for cost measurement,such as retail inventory method, are similar under both US GAAP and IFRS. Further, under both sets of standards, the cost of inventory includes all direct expenditures to ready inventory for sale, including allocable overhead, while selling costs are excluded from the cost of inventories, as are most storage costs and general administrative costs.
