At December 31, 2008, Voga decided to change the depreciation method on its office equipment from double-declining balance to straight-line. The equipment has an original cost of $100,000 when purchased on January 1, 2006. it has a 10-year useful life and no salvage value. Depreciation expense recorded prior to 2008 under the double-declining balance method was $36,000. Voga has already recorded 2008 depreciation expense of $12,800 using the double-declining balance method. 4. Before 2008, Voga accounted for its income from long-term construction contracts on the completedcontract basis. Early in 2008, Voga changed to the percentage-of-completion basis for accounting purposes. It continues to use the completed-contract method for tax purposes. Income for 2008 has been recorded using the percentage-of-completion method. The following information (on page 1199) is available.
