For example, the store will need an initial (year-0) investment in working capital of .20 × 34,000 × $40 = $272,000. Plant and equipment necessary to establish the Giftware business will require an additional investment of $212,000. This investment will be depreciated using MACRS and a 3-year life. After 4 years, the equipment will have an economic and book value of zero. The firm's tax rate is 30%. What is the net present value of the project? The discount rate is 20%.
