Answer: It can lead to dysfunctional decision making.
Step-by-step explanation:
It may lead to a dysfunctional decision making. For example, a division with a current ROI of 30% will not wish to accept a project that offers a ROI of 25%, because it would dilute the current figure it has. However, the 25% ROI may be able to meet or exceed the company’s target.
Return on investment (ROI) increases with the asset age if the net book value (NBV) is used, thereby giving managers incentive to hang on to possibly obsolescent and inefficient machines. It may also encourage the manipulation of the profit and the capital employed figures to improve results, e.g to obtain a bonus payment. The use of different accounting policies can lead to confusion in comparisons e.g. depreciation policy.
