Brioche Incorporated is a private company that uses IFRS for financial reporting. The company acquired equipment for $90,000 on 1 January 20X1. At acquisition, Brioche estimated the equipment would have a useful life of 10 years. The residual value was estimated at $6,000. Brioche Incorporated recorded depreciation on the equipment for 4 years using straight-line depreciation. During this period, the equipment had been used with less intensity than anticipated due to unforeseen cash flow which allowed for the purchase of additional equipment which was used to share the load. At the 20X5 reporting date, before recording the annual adjusting entry for depreciation expense, Brioche re-evaluated the estimates concerning this equipment and determined that the original useful life should have been estimated at 12 years and that the residual value is actually $6,500.

Required:

1. Do you think it is reasonable that the estimated useful life and residual value changed at the 20X5 reporting date? Explain your answer.

2. Calculate the adjustment needed for 20X1 to 20X4 for the incorrect depreciation recorded.

3. Calculate annual depreciation expense for 20X5 and provide the required entry.
