Michael Cleaners needs a new steam finishing machine that costs $100,000. The company is evaluating whether it should lease or purchase the machine. The equipment falls into the MACRS 3-year class, and it would be used for 4 years and then sold, because the firm plans to move to a new facility at that time. The estimated value of the equipment after 4 years is $10,000. A maintenance contract on the equipment would cost $3,000 per year, payable at the beginning of each year. Alternatively, the firm could lease the equipment for 4 years for a lease payment of $29,000 per year, payable at the beginning of each year. The lease would include maintenance. Due to special circumstances, the firm is in the 20% tax bracket, and it could obtain debt at a before-tax cost of 10%. If there is a positive Net Advantage to Leasing the firm will lease the equipment. Otherwise, it will buy it. MACRS rates for Years 1 to 4 are 0.3333, 0.4445, 0.1481, and 0.0741.

What is the after-tax debt rate that should be used to perform the lease / buy analysis?

What is the after-tax cash flow effect of selling the machine at the end of year 4?

What is the NAL?
