On April 7, 2024, Scoop Corporation purchased two excavators at an auction for a combined total cost of $330,000. The excavators were listed in the auction catalogue at $125,000 for excavator A and $270,000 for excavator B. Immediately after the auction, Scoop had the excavators professionally appraised so it could purchase adequate insurance coverage. The appraisal put a fair value of $111,000 on excavator A and $259,000 on excavator B.
On April 10, Scoop paid a total of $4,000 in transportation charges for the two excavators. On April 28, Scoop paid $9,000 for improvements to excavator B and no further expenditures were made for excavator A. On April 30, 2024, both excavators were ready to be used.
The company expects excavator A to last eight years and to have a residual value of $7,500 when it is removed from service, and it expects excavator B to be useful for six more years and have a residual value of $17,800 at that time. Due to the different characteristics of the two excavators, different depreciation methods will be used for them: excavator A will be depreciated using the double-diminishing-balance method and excavator B using the straight-line method.
