4. If Karp had used FIFO instead of LIFO, Karp’s retained earnings as of 31 December 2009 would have been higher by an amount closest to:
选项：
A. $117 million.
B. $124 million.
C. $155 million.
解释：
B is correct.
Karp’s retained earnings (RE) under FIFO equals Karp’s retained earnings under LIFO plus the after-tax LIFO reserve. Therefore, for the year ended 31 December 2009, Karp’s retained earnings under FIFO equals:
RE (FIFO method) = RE (LIFO method) + LIFO reserve × (1 – Tax rate) = $787 million + 155 million × (1 – 20%) = $911 million
Therefore, the increase in retained earnings is:
Increase in RE = RE (FIFO method) – RE (LIFO method) = $911 million – 787 million = $124 million
