Tanner Company purchased equipment on May 1, 2018 for $800,000. It is estimated that the equipment will have a $80,000 residual value at the end of its 6-year useful life. It is also estimated that the equipment will produce 120,000 units over its 6-year life. Assuming 8,000 units of product are produced in 2018 and 12,600 units are produced in 2019, what is the net carrying (book) value of the equipment at December 31, 2019 according to the units-of production depreciation method?
