Income Return
Income Return is the return on the ordinary dividends paid to shareholders of a security. It is the ratio of the amount of ordinary dividends since the end of the previous period up to and including the end of the period of interest to the price at the end of the previous period. It is similiar to a dividend yield.
Income Return can be derived from Total Return and Capital Appreciation as follows:
iret(t) = tret(t)-aret(t)
where iret is the income return for time t, tret is the total return for time t, and aret is the capital appreciation for time t.
