If performance is being measured by ROI, both Division A and Division C probably would reject the 15% investment opportunity. These divisions’ ROIs currently exceed 15%; accepting a new investment with a 15% rate of return would reduce their overall ROIs. Division B probably would accept the 15% investment opportunity because accepting it would increase the division’s overall rate of return.
If performance is measured by residual income, both Division A and Division B probably would accept the 15% investment opportunity. The 15% rate of return promised by the new investment is greater than their required rates of return of 14% and 10%, respectively, and would therefore add to the total amount of their residual income. Division C would reject the opportunity because the 15% return on the new investment is less than its 16% required rate of return
