On January 1, 2019, Zui Corporation purchased a building and equipment that had the following useful lives, residual values, and costs:

Building: 40-year estimated useful life, $50,000 residual value, $1,200,000 cost
Equipment: 12-year estimated useful life, $10,000 residual value, $130,000 cost

The building was depreciated under the double-declining-balance method through 2022. In 2023, the company decided to switch to the straight-line method of depreciation because of a change in the pattern of benefits received. In 2023, Zui decided to change the equipment’s total useful life to 15 years, with a residual value of $5,000 at the end of that time. The equipment is depreciated using the straight-line method.

Instructions

a. Prepare the journal entry(ies) necessary to record the depreciation expense on the building in 2023. (Ignore income tax effects.)

b. Calculate the depreciation expense on the equipment for 2023. (Ignore income tax effects and round to the nearest dollar.)

c. Assume the role of Zui’s auditor, and discuss any issues related to the above changes in estimate.
