Final answer:
MIRR is a financial metric used to assess investments, considering cash flows reinvested at the firm's WACC instead of the IRR. The risk level influences the stability of an investment's returns compared to expected returns, and the actual rate of return accounts for all forms of return over a period.
Step-by-step explanation:
The Modified Internal Rate of Return (MIRR) is a financial metric used to evaluate the attractiveness of investments or projects. Unlike the traditional Internal Rate of Return (IRR), which assumes that all cash flows generated by a project are reinvested at the IRR, the MIRR assumes reinvestment at the firm's cost of capital or a different rate that reflects the reality of reinvestment opportunities.
To calculate the MIRR, you need to know the project's initial investment, expected cash flows, and the reinvestment rate (typically the firm's weighted average cost of capital (WACC)).
Risk in investment terms refers to the uncertainty surrounding the actual returns that an investment or project will generate, as opposed to the expected rate of return.
High-risk investments fluctuate widely around their expected returns, while low-risk investments tend to have actual returns that are closer to their expected returns. The actual rate of return includes all forms of return, including capital gains and interest, earned over a period.
