The ABC Company purchased a solar powered electrical generator on March 9, 2005 for \$1.5 million. At that time, it was estimated that the generator would have a useful life of 20 years and a salvage value of \$50,000. Over its life span, it was estimated that the generator would produce 30M gigawatts of electricity. In the 2005 year, the generator produced 800,000 gigawatts; in the 2006 year – 1.2M gigawatts, and finally in the 2007 year – 1.0M gigawatts (i.e. 500,000 gigawatts up to July 17).

On July 17, 2007, during a management meeting, the senior engineer notified the Controller that there were actually 35 years of useful life remaining on the generator (or 35M gigawatts of electricity) now that a \$300,000 retrofit had been completed. In addition, the engineer stated that the generator would likely have a salvage value of only \$10,000. After further research, the Controller agreed with the engineer’s stated information and realized that a “change of accounting estimate”, in respect of the amortization expense, would be required.
