The Pronghorn Transportation Company uses a responsibility reporting system to measure the performance of its three investment centers: Planes, Taxis and Limos. Segment performance is measured using a system of responsibility reports and return on investment calculations. The allocation of resources within the company and the segment managers' bonuses are besed in part on the results shown in these reports. Recently, the company was the victim of a computer virus that deleted portions of the company's accounting records.
