Murray's Fish Market, a store that specializes in providing fresh fish to the Nashville, Tennessee, area, installed a new refrigeration unit in January 2012 at a cost of $27,500. The refrigeration unit has an expected life of 8 years and a residual value of $500 when installed. As the fish market's business increased, it became apparent that renovations were necessary so that the capacity of the refrigeration unit could be increased. In January 2014, Murray's spent $18,785 to install an additional refrigerated display unit (that was connected to the original unit) and replace the refrigeration coils. After this addition and renovation, Murray's Fish Market estimated that the remaining useful life of the original refrigeration unit was 12 years and that the residual value was now $1,000.
