A truck was acquired on July 1, 2008, at a cost of $216,000. The truck had a six-year useful life and an estimated salvage value of $24,000. The straight-line method of depreciation was used. On January 1, 2011, the truck was overhauled at a cost of $20,000, which extended the useful life of the truck for an additional two years beyond that originally estimated (salvage value is still estimated at $24,000). In computing depreciation for annual adjustment purposes, expense is calculated for each month the asset is owned.
