On January 1, Year 7, Blette Corp. purchased a machine having an estimated useful life of 8 years and no salvage value. The machine was depreciated by the double-declining-balance (DDB) method for both financial statement and income tax reporting. On January 1, Year 9, Blette justifiably changed to the straight-line method for both financial statement and income tax reporting. Accumulated depreciation at December 31, Year 8, was $525,000. If the straight-line method had been used, the accumulated depreciation at December 31, Year 8 , would have been $350,000. The retroactive adjustment to the accumulated depreciation account on January 1, Year 9 , as a result of the change in depreciation method is $175,000 $525,000 $0 $350,000
