there are some wonderful people like S2000 to answer…but u have to ask very clearly…we are usually so engrossed in ques that we assume the reader is on the same ground
The question is to calculate “the contribution that the terminal value of the residual income stream in 5 years will contribute to the current value of equity”.
As you have already got current year RI = Current NI - Begining BV of Equity capital x Cost of equity = 8 - (12,4% x 20,97) = 5,4
Take this current year to next 5 years = 5,4 x 1.155 as annual growth rate of RI is 15%
