The first audit of the books of Swift Limited was recently carried out for the year ended December 31, 2021. Swift follows IFRS. In examining the books, the auditor found that certain items had been overlooked or

might have been incorrectly handled in the past:

1. At the beginning of 2019, the company purchased a machine for $420,000 (residual value of $30,000) that had a useful life of six years. The bookkeeper used straight-line depreciation but failed to deduct the residual value in calculating the depreciation base for the three years.

2. Swift purchased another company early in 2017 and recorded goodwill of $500,000. Swift amortized $30,000 of goodwill in 2017, and $60,000 in each subsequent year. The tax treatmenf for goodwill was properly applied.

Assuming the company has a tax rate of 30%.

Instructions
