Corporation A produces staplers. The corporation is deciding whether to build a new plant, for an initial investment of $200,000. The corporation projects to receive cashflows of $20,000 a year for 10 years by selling the output of the plant. Moreover, in year 11 the corporation could decide to convert the plant to produce a new product. The conversion would cost $10,000, and the new product would be sold for the following 50 years, with expected cash inflows per year of $50,000. The required rate of return for investments in stapler production is 10% per year, while the one for investments in the production of new products is 15% per year.
