Nuke-A-Bird, Inc. sells frozen chicken meals. The company needs to purchase some new freezers for storing inventory. If the freezers are purchased, they will replace old freezers purchased 10 years ago for $105,000, and these are being depreciated on a straight-line basis to a zero book value (15-year depreciable life). The old freezers can be sold for $60,000 today, and $2,000 in 5 years. The new freezers will cost $200,000 installed and will be depreciated on a straight-line basis to a book value of 0. The new freezers will have a salvage value of $25,000 at the end of the 5th year. The firm expects to increase its pre-tax revenues by $50,000 per year if the new freezers are purchased, but cash expenses will also increase by $6,000 because the new freezers require greater electrical expense. If the firm's cost of capital is 10 percent and its tax rate on income and capital gains is 34%, what is the NPV of the new freezers?

a) What is the annual difference in the FCFF from the new project?

b) Should the old ones be replaced?
