(MIRR) 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 federal law) that has capacity for five years. The $9.6 million expenditure required to construct the new landfill results in negative cash flows at the end of years 5, 10, and 15. This change in sign on the stream of cash flows over the 20-year contract period introduces the potential for multiple IRRs, so Star'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 $3.5 million (this does not reflect the cost of constructing the landfills every five years). Star uses a 10.4% discount rate to evaluate its new projects, so it plans to discount all the construction costs every five years back to year 0 using this rate before calculating the MIRR.
a.What are the project's NPV, IRR, and MIRR?
b.Is this a good investment opportunity for Star Industries? Why or why not?
NPV | $ 7.802402 million | or | 7,802,402.09 | $ |
IRR | 24.04% | |||
MIRR | 12.14% |

20 | 3.50 | 3.50 | 0.1382 | 0.48 | ||
NPV | 7.802402 |
Thus NPV = $7.802402 million or $7,802,402.09
IRR: This has been computed using trial and error approach as shown below:
Year (n) | Costs (in $ millions) | Cash inflow (in $ millions) | Net cash flow (in $ millions) | 1+r | PVIF = 1/1+R^n | PV = net cash flow * PVIF |
- | - 9.6 | - 9.6 | 1.1 | 1.0 | - 9.6 | |
1 | 3.5 | 3.5 | 0.9 | 3.2 | ||
2 | 3.5 | 3.5 | 0.8 | 2.9 | ||
3 | 3.5 | 3.5 | 0.7 | 2.6 | ||
4 | 3.5 | 3.5 | 0.7 | 2.4 | ||
5 | - 9.6 | 3.5 | - 6.1 | 0.6 | - 3.7 | |
20 | 3.5 | 3.5 | 0.1 | 0.5 | ||
NPV | 7.802402 |
Thus IRR = 24.04%
MIRR:
MIRR formula is: Present value of costs = Terminal value/(1+MIRR)^n
Present value of costs = 9.6 + 9.6/1.104^5 + 9.6/1.104^10 + 9.6/1.104^15 = 21.20 million
Terminal value = 3.50*(1.104^19)+3.50*(1.104^18)+…..3.50*(1.104^1) + 3.5 = 209.80 million
Thus 21.20 million = 209.80 million/(1+MIRR)^20
Or (1+MIRR)^20 = 9.90
OR 1+Mmirr = 1.1214
Or MIRR = 12.14%
(b): Yes, this is a good investment opportunity because NPV is positive, IRR > hurdle rate of 10.4% and MIRR > hurdle rate of 10.4%
