5) In 1993, Herman Moore Company completed the construction of a building at a cost of $2,000,000 and first occupied it in January 1994. It was estimated that the building will have a useful life of 40 years and a salvage value of $60,000 at the end of that time. Early in 2004, an addition to the building was constructed at a cost of $500,000. At that time, it was estimated that the remaining life of the building would be, as originally estimated, an additional 30 years, and that the addition would have a life of 30 years and a salvage value of $20,000. In 2022, it is determined that the probable life of the building and addition will extend to the end of 2053 or 20 years beyond its original estimate.
