current costs. The unit cost of these earlier layers may be much lower if
LIFO has been used than if FIFO has been used because they represent
much earlier acquisitions. Therefore, the company may actually record
lower cost of goods sold using LIFO than using FIFO, resulting in higher
Q13-11 This is because of the mechanics of the LIFO and FIFO methods. Under
LIFO, the most recent costs of inventory purchases are charged off to cost
of goods sold. Older costs are reported as ending inventory. When prices

the inventory must be written down to the lower value. The purpose of this
