Woodward Corporation purchases a new machine for $50,000 on January 1, 2013. The machine has a four-year estimated service life and an estimated salvage value of zero. After paying the cost of running and maintaining the machine, the firm enjoys a $25,000-per-year excess of revenues over expenses (except depreciation and taxes). In addition to the $25,000 from the machine, other pretax income each year is $35,000. Woodward uses straight-line depreciation for financial reporting and depreciates the machine for tax reporting using the following percentages: 33% in the first year, 44% in the second, 15% in the third, and 8% in the fourth. Depreciation is Woodward's only temporary difference. Woodward pays combined federal and local income taxes at a rate of 40% of taxable income.
