Star Industries owns and operates landfills for several municipalities throughout the Midwestern part of the U.S. Star typically contracts with the municipality to provide landfill services for a period of 20 years. The firm then constructs a lined landfill(required by federallaw) that has capacity for five years. The $9 million expenditure required to construct the new landfill results in negative cash flows at the end of years5, 10, and 15. This change in sign on the stream of cash flows over the20-year contract period introduces the potential for multipleIRRs, soStar's management has decided to use the MIRR to evaluate new landfill investment contracts. The annual cash inflows to Star begin in year 1 and extend through year 20 are estimated to equal $3.3 million(this does not reflect the cost of constructing the landfills every fiveyears). Star uses a 10.4% discount rate to evaluate its newprojects, so it plans to discount all the construction costs every five years back to year 0 using this rate before calculating the MIRR.

b.Is this a good investment opportunity for StarIndustries? Why or whynot?
