It was estimated that the building will have a useful life of 40 years and a salvage value of $75,200 at the end of that time. Early in 2009 , an addition to the building was constructed at a cost of $620,000. 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 $24,800. 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.
