The Collins Corporation purchased office equipment at the beginning of 2019 and capitalized a cost of $2,236,000. This cost included the following expenditures:

Purchase price	$	1,980,000
Freight charges		44,000
Installation charges		34,000
Annual maintenance charge		178,000
Total	$	2,236,000

The company estimated an eight-year useful life for the equipment. No residual value is anticipated. The double-declining-balance method was used to determine depreciation expense for 2019 and 2020. In 2021, after the 2020 financial statements were issued, the company decided to switch to the straight-line depreciation method for this equipment. At that time, the companys controller discovered that the original cost of the equipment incorrectly included one year of annual maintenance charges for the equipment.
