Wolfson Corporation has decided to purchase a new machine that costs $2.9 million. The machine will be depreciated on a straight-line basis and will be worthless after four years. The corporate tax rate is 21 percent. The Sur Bank has offered Wolfson a four-year loan for $2.9 million. The repayment schedule is four yearly principal repayments of $725,000 and an interest charge of 7 percent on the outstanding balance of the loan at the beginning of each year. Both principal repayments and interest are due at the end of each year. Cal Leasing Corporation offers to lease the same machine to Wolfson. Lease payments of $840,000 per year are due at the beginning of each of the four years of the lease.
