A company invests $1,750,000 in MACRS GDS 5-year property. Measured in constant dollars, the investment yields net revenue of $300,000 the first year; thereafter, net annual revenue increases 8% per year for 5 years and remains at that level for the balance of the 10-year planning horizon, at which time the equipment has a constant dollar salvage value of $500,000. Inflation is anticipated to equal 2% per year over the planning horizon. Section 179 expense deduction and 50% bonus depreciation are available. A real required return on investment of 6% is used by the company in performing economic justifications. Based on an income tax rate of 25%, calculate the value of the a) after-tax real external rate of return, b) economic value added from the investment, and c) after-tax discounted payback period. Show all work, including BOYBV and yearly EVA values measured in then-current dollars. Interpolate DPBP to two decimal places.
