This document discusses the valuation and accounting of inventory. It defines inventory as assets held for sale, in production, or as supplies. Inventory should be valued at the lower of cost or net realizable value. Cost includes all purchase costs, conversion costs like direct labor and allocated overheads, and other costs to bring inventory to its present condition. Common costing methods are specific identification, FIFO, and weighted average. Disclosures include accounting policies and total inventory carrying amounts.
