GR Corporation uses the last-in, first out (LIFO) method of accounting for inventory and $70,000 is reported as cost of goods sold (COGS) on their income statement. However, if GR had used first-in, first-out (FIFO), the COGS would have been $60,000. If the ending LIFO reserve (LR) reported in the financial statements is $40,000, the beginning LIFO reserve is:
Beginning LR + ΔLR = Ending LR ΔLR = COGS(LIFO) – COGS(FIFO) = $70,000 – 60,000 = $10,000 Beginning LR = $40,000 – 10,000 = $30,000 |
