Early in 2021, the company made a decision to stop making the items produced by the machinery and buy the items instead. As a result, the remaining useful life was decreased to two years and the residual value was increased to a total of $120,000. At the beginning of 2021, it was determined that the estimated life of the office furniture should be reduced by two years and the residual value decreased by $6,400. The company calculates depreciation using the straight-line method to the nearest month.
