Marcus Lim, the cost accountant for Hi-Power Mower Company, recently installed activity-based
costing2 at Hi-Power’s St. Louis lawn tractor (riding mower) plant where three models, – the 8-
horsepower Bladerunner, the 12-horsepower Quickcut, and the 18-horsepower Supercut – are
manufactured. Marcus’s new product costs for those three models show that the company’s traditional
costing system had been significantly under costing the 18-horsepower Supercut. This was due primarily
to the lower sales volume of the Supercut compared to the Bladerunner and the Quickcut.
Before completing his analysis and reporting these results to management, Marcus is approached by his
friend Ray Pon, who is the production manager for the 18-horsepower Supercut model. Ray has heard
from one of Marcus’s staff about the new product costs and is upset and worried for his job because the
new costs show the Supercut to be losing, rather than making, money.
At First Ray condemns the new cost system, whereupon Marcus explains the practice of activity-based
costing and why it is more accurate than the company’s present system. Even more worried now, Ray
begs Marcus, “Massage the figures just enough to save the line from being discontinued. You don’t
want me to lose my job do you? Anyway, nobody will know.”
Marcus holds firm but agrees to recompute all his calculations for accuracy before submitting his costs
to management.
