Jantz Corporation purchased a machine on July 1, 2005, for $750,000. The machine was estimated to have a useful life of 10 years with an estimated salvage value of $42,000. During 2008, it became apparent that the machine would become uneconomical after December 31, 2012, and that the machine would have no scrap value. Accumulated depreciation on this machine as of December 31, 2007, was $177,000. What should be the charge for depreciation in 2008 under generally accepted accounting principles?
