This document discusses accounting for inventories. It covers classifying inventory, determining inventory quantities through physical counts and ownership rules, inventory costing methods including specific identification, FIFO, LIFO, and average cost, and the financial statement effects of using different cost flow assumptions. The key points are determining inventory ownership, applying cost flow assumptions like FIFO and LIFO to value ending inventory balances, and how the choice of assumptions like LIFO can impact reported income during inflationary periods by reducing taxable income.
