E11-12B (Depreciation Computation—Addition, Change in Estimate) In 1992, Lincoln Company completed the construction of a building at a cost of $4,000,000 and first occupied it in January 1995. It was estimated that the building will have a useful life of 40 years and a salvage value of $200,000 at the end of that time.
Early in 2002, an addition to the building was constructed at a cost of $1,500,000. At that time it was estimated that the remaining life of the building would be, as originally estimated, an additional 32 years, and that the addition would have a life of 32 years, and a salvage value of $20,000.
In 2016, it is determined that the probable life of the building and addition will extend to the end of 2054 or 10 years beyond the original estimate.
