Exercise #4: Change in Estimate At the very beginning of 2019, Robotics, Inc. acquired a manufacturing facility for $12 million $9 million of the purchase price was allocated to the building. Depreciation for 2019 and 2020 was calculated using the double-declining balance method, a 25-year useful life, and a $1 million residual value. In 2021, the estimates of useful life and residual value were changed to 20 years and $500,000, respectively Required: Calculate depreciation on the building for 2021. Round calculations to the nearest whole dollar. Exercise #5: Change in Depreciation Method Refer back to Exercise 4. Assume that instead of changing the useful life and residual value in 2021 the company switched to the straight-line method of depreciation Required: How should Robotics account for the change? What is depreciation on the building for 20212 Round calculations to the nearest whole dollar
