HCA must install a new $1.4 million computer to track patient records in its multiple service areas. It plans to use the computer for only three years, at which time a brand new system will be acquired that will handle both billing and patient records. The company can obtain a 10 percent bank loan to buy the computer or it can lease the computer for three years. Assume that the following facts apply to the decision: The computer falls into the three-year class for tax depreciation, so the MACRS allowances are 0.33, 0.45, 0.15, and 0.07 in Years 1 through 4. The company's marginal tax rate is 34 percent. Tentative lease terms call for payments of $475,000 at the end of each year.
