During the four fiscal quarters of 2001 and the first quarter of 2002, WorldCom incorrectly capitalized access charges to local networks as assets (as explained in Box 2.3). The amount of costs capitalized were as follows:
First quarter, 2001 ............ $780 million
Second quarter, 2001 ........... $605 million
Third quarter, 2001 ........... $760 million
Fourth quarter, 2001 .......... $920 million
First quarter, 2002 ........... $790 million
Suppose WorldCom amortized these capitalized costs straight-line over five years (20 quarters). Calculate the amount of the overstatement of income before tax for each of the five quarters.
