The usual practise is to give preferences to the Investment Projects with higher MIRR and make a direct comparison of MIRR against the Weighted Average Cost of Capital (WACC).
MIRR is similar to IRR in nature but free from some common IRR issues.
The corporate investment policy usually dictates that:
