Wimot Trucking Company uses the units-of-production depreciation method because units-of-production best measures wear and tear on the trucks. Consider these facts about one Mack truck in the company’s fleet. When acquired in 2021, the rig cost $360,000 and was expected to remain in service for 10 years or 1,000,000 miles. Estimated residual value was $90,000. The truck was driven 80,000 miles in 2021, 120,000 miles in 2022, and 160,000 miles in 2023. After 44,000 miles, on March 15, 2024, the company traded in the Mack truck for a less expensive Freightliner. Wimot also paid cash of $20,000. Fair market value of the Mack truck was equal to its net book value on the date of the trade.
