The performance of the divisional managers is measured based on the return on investment (ROI) achieved by their division for the year, with a minimum target of 10% ROI. The bonus payment structure for ABC Sdn Bhd, ranges from 1% to a maximum of 20% of the annual salary.

Each divisional manager is paid an average salary of RM180,000 per annum. During the recent management meeting, the new sales and marketing director of ABC Sdn Bhd has commented "It is not fair to use ROI to measure the performance of our divisional managers. Using ROI, we are paying more bonuses to Division X's manager. This is so unfair to Division Y's manager. We should be using residual income in evaluating their performance."
