A corporation acquired a truck on July 1, 2012, at a cost of $162,000. The truck has a six-year useful life and an estimated salvage value of $18,000. The straight-line method of depreciation was used. On January 1, 2015, the truck was overhauled at a cost of $15,000, which extended the useful life of the truck for an additional two years beyond that originally estimated (salvage value is still estimated at $18,000). In computing depreciation, the corporation uses the nearest full month assumption to calculate depreciation.
Calculate the depreciable base of the truck, before and after the overhaul on January 1, 2015.
