modified internal rate of return (MIRR) is the discount rate that causes the PV of a project’s terminal value (TV) to equal the PV of costs
a project’s terminal value (TV) is found by compounding inflows at WACC
MIRR assumes cash inflows are reinvested at WACC, which is reasonable. rule is that we Accept the project if MIRR > rWACC
For 2 mutually exclusive projects of equal size and the same life, NPV and MIRR will always lead to the same decision
The profitability index (PI) is the present value of future cash flows divided by the initial cost. it's the scale version of NPV. measures the “bang for the buck"
with pi, To accept a project, PI > 1. when PI > 1 its equivalent to NPV > 0
pi = pv of project's cf / inital cost
the Payback period is the number of years required to recover a project’s cost, or how long it takes to get the business’s money back
firms establish a benchmark payback period; projects whose payback exceeds this benchmark are rejected
strengths of the payback method include:
Indicates a project’s risk and liquidity
Easy to calculate and understand
Weaknesses of the payback method:
Ignores the time value of money (tvm)
Ignores CFs occurring after the payback period
Not necessarily related to investor wealth
the discounted payback period is Defined as the number of years required to recover the investment from discounted net cash flows
Projects with shorter payback periods are preferred to those with longer ones
As an indicator of how long funds are to be tied up in a project, payback methods measure the project’s liquidity and risk
NPV is the single most important method, directly measuring the dollar benefit of the project to shareholders. IRR is ranked second
IRR, MIRR, and PI all contain information about a project’s “safety margin. MIRR avoids the multiple IRR problem and PI indicates the project’s risk
PB and discounted PB indicate both the risk and the liquidity.
equivalent annual annuity (eaa) measurement should only be used for unequal life projects
