ABC Inc. is considering the replacement of an old printing machine with a new one that will increase revenue by $3,000 per year (A revenue = $3,000/year). The new machine costs $15.000, has an estimated life of 6 years, and can be depreciated straight line to a zero salvage value over the next 6-year period. The new machine is expected to have a disposal value of $3,000 at the end of its estimated life. The old machine was bought 4 years ago at $5,000 and is being depreciated under the straight-line method to a zero salvage value (original life = 10 years). The old machine, however, is not likely to have any disposal value at the end of its useful life (6 years from now) but has a current market value of $2,000. The applicable corporate tax rate is 25%, and the firm's WACC is 10%. a) Should the new machine replace the old one? Assume that the old machine can be used for another six years if not replaced. b) Create a two-way data table showing the sensitivity of NPV with respect to the change in annual revenue generated by the new machine, and the expected disposal value of the new machine (at the end of its 6-year expected life). Use a $2,500 to $3,500 range for both the change in annual revenue and the disposal value of the new machine (with a $100 increment).
