Inventory

Exam insight

Inventory is one of the most calculation-heavy MCQ topics in FAR: FIFO, LIFO, weighted average, and LCNRV. The AICPA's favorite trick is a LIFO liquidation that asks about gross profit. When LIFO layers run out, older (lower) costs flow to COGS and push gross profit up, and candidates who miss this get it wrong every time. One more thing to lock in: LCNRV is applied item by item, not to the inventory as a whole.
