On January 1, Year 1, Burnham Company purchased a machine for $2,580,000; however, the cost of the machine was recorded as repairs expense. The machine's useful life was expected to be 12 years with no residual value. Burnham uses straight-line depreciation. What is the amount of the credit to retained earnings in the journal entry to correct the error if the error is discovered during year 4 (after 3 years)? Ignore income tax.
