Investment Income
Investment income or earnings refers to any increase or decrease resulting from interest, dividends or changes in the value of the underlying asset.  This is often referred to as taking a Total Return Approach to investment management which is that used by most university endowment and charitable funds.

This is a better balanced and more comprehensive view of  portfolio management and allows one to potentially increase income (total return) and reduce risk as compared with an approach that focuses on interest and dividends only.
