Charlene is evaluating a capital budgeting project that should last for 4 years. The project requires $800,000 of equipment and is eligible for 100% bonus depreciation. She is unsure whether immediately expensing the equipment or using straight-line depreciation is better for the analysis. Under straight-line depreciation, the cost of the equipment would be depreciated evenly over its 4-year life. The companys WACC is 8%, and its tax rate is 25%. a. What would the depreciation expense be each year under each method? b. Which depreciation method would produce the higher NPV, and how much higher would it be?
