Lewis Health System Inc. has decided to acquire a new electronic health record system for its Richmond hospital. The system receives clinical data and other patient information from nursing units and other patient care areas, then either displays the information on a screen or stores it for later retrieval by physicians. The system also permits patients to call up their health record on Lewis's website. The equipment costs $1,000,000, and, if it were purchased, Lewis could obtain a term loan for the full purchase price at a 10 percent interest rate. The equipment is classified as a special-purpose computer, so it falls into the MACRS three-year class. If the system were purchased, a four-year maintenance contract could be obtained at a cost of $20,000 per year, payable at the beginning of each year. The equipment would be sold after four years. Since real-time display system technology is changing rapidly, the best estimate of its residual value at that time is only $200,000. As an alternative to the borrow-and-buy plan, the equipment manufacturer informed Lewis that Consolidated Leasing would be willing to write a four-year guideline lease on the equipment, including maintenance, for payments of $260,000 at the beginning of each year. Lewis's marginal federal-plus-state tax rate is 40 percent. You have been asked to analyze the lease-versus-purchase decision. Should Lewis Health System lease or purchase the equipment? Please explain and show your work.
