Fanning Electronics is considering investing in manufacturing equipment expected to cost $250,000. The equipment has an estimated useful life of four years and a salvage value of $ 19,000. It is expected to produce incremental cash revenues of $125,000 per year. Fanning has an effective income tax rate of 40 percent and a desired rate of return of 12 percent. (PV of $1 and PVA of $1) (Use appropriate factor(s) from the tables provided.) Required a. Determine the net present value and the present value index of the investment, assuming that Fanning uses straight-line depreciation for financial and income tax reporting. b. Determine the net present value and the present value index of the investment, assuming that Fanning uses double-declining- balance depreciation for financial and income tax reporting. d. Determine the payback period and unadjusted rate of return (use average investment), assuming that Fanning uses straight-line depreciation. e. Determine the payback period and unadjusted rate of return (use average investment), assuming that Fanning uses double- declining-balance depreciation. (Note: Use average annual cash flow when computing the payback period and average annual income when determining the unadjusted rate of return.) X Answer is complete but not entirely correct.
