Recording and Reporting an Error, Comparative Statements Beckham Corporation had never been audited before December 31 of Year 4, the current year. Before the arrival of the auditors, the controller prepared comparative financial statements showing the results of Year 3 and Year 4 . The accounts for Year 4 have not been closed. The auditors discovered that an invoice dated January of Year 1 for $14,400 (paid in cash at the time) was debited to Year 1 operating expenses, although it was for the purchase of equipment. The equipment has an estimated useful life of 10 years and no estimated residual value. Reported income on the financial statements prepared by the company (before discovery of the error) was Year 1, \$17,600; Year 2, \$35,200; Year 3, \$48,000; and Year 4, \$52,800. Disregard income tax considerations and assume that Beckham uses straight-line depreciation. Required a. Determine the correct net income for Year 1, Year 2, Year 3, and Year 4. b. Prepare the Year 4 entries to record the (1) correction of the Year 1 error and (2) depreciation expense for Year 4. c. Show how the correction is reported on the Year 4 comparative balance sheet, the Year 4 statement of retained earnings, and the Year 4 income statement.
