(b) You are currently reviewing the audit files of two (2) companies. The audit supervisor has summarised the critical audit issues for each of the companies for your attention: 1) ABC changed its depreciation method from straight-line to reducing balance and the company treats it as a change in accounting policy. 2) DEF did not depreciate its freehold land and buildings because the directors argue that the market value of the freehold land and building is greater than its original cost. 6 Required: Critically evaluate and recommend an approriate accounting treatment for each of the above situations.
