In 1998, Oriole Company completed the construction of a building at a cost of $2,400,000 and first occupied it in January 1999. It was estimated that the building will have a useful life of 40 years and a salvage value of $72,000 at the end of that time. Early in 2009, an addition to the building was constructed at a cost of $600,000. 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 $24,000. In 2027 , it is determined that the probable life of the building and addition will extend to the end of 2058 , or 20 years beyond the original estimate.
