For financial reporting purposes, depreciation is recognised on a straight line basis, over 20 years for buildings (estimated residual value $250,000), eight years for plant and 10 years for equipment. For tax purposes, straight line depreciation is applied over 40, 10 and eight years respectively. 2. After reviewing all relevant information, the directors determined that, at 30 June 2018, the plant was impaired by $250,000 (this is not reflected in the amounts presented in the trial balance). 3.
