a. Down. Notice that lower of cost or market is lower than
acquisition
cos
t
(FIFO); current market price is less than
cost.
b. Up. FIFO means last-in, still-here. The last purchases (FIFO =
LISH) cost $44,000 and the earlier purchases (LIFO = FISH) cost
$41,800. Also, lower-of-cost-or-market basis shows acquisition
costs, which are greater than or equal to current cost.
c. LIFO Cost. Other things being equal, the largest income
results from the method that shows the largest increase in
inventory during the year.
Margin = Revenues – Cost of Goods
Sold
= Revenues – Beginning Inventory – Purchases + Ending
Inventory
= Revenues – Purchases + Increase in Inventory.
Because the beginning inventory in 2010 is zero, the method
with the largest closing inventory amount implies the largest
increase and hence the largest income.
d. Lower of Cost or Market. The method with the “largest increase
in inventory” during the year in this case is the method with the
smallest decrease, because all methods show declines in
inventory during 2011. Lower of cost or market shows a
decrease in inventory of only $3,000 during 2011—the other
methods show larger decreases ($3,800; $4,000).
e. Lower of Cost or Market. The method with the largest increase
in inventory: $10,000. LIFO shows a $5,400 increase,
whereas FIFO shows $8,000.
f. LIFO Cost. The lower income for all three years results
from the method that shows the smallest increase in inventory
over the three years. Because all beginning inventories were
zero under all methods, we need merely find the method with
the smallest ending inventory at
2012
year-end.
