No immediate investment is required, but it must raze the existing buildings over a four- year period and at the end of the fourth year invest $2,400,000 for new construction. It will collect all revenues and pay all costs for a period of 10 years, at which time the entire project, and properties thereon, will revert to the city. The net cash flows are estimated to be as follows: Year End Net Cash Flow 1 $500,000 2 300,000 3 100,000 -2,400,000 5 150,000 200,000 250,000 300,000 350,000 400,000 Tabulate the PW versus the interest rate and determine whether multiple IRRs exist.
