Reading 39 - Private Company Valuation - Excess Earnings Method
As per the steps (precise - step-6 on page-558) given in the reading - the numerator should have GROWTH multiplied with Residual Income divided by (r-g).
Specifically, the formula is -
Value of intangible asset = (Residual Income * g) / (r-g)
HOWEVER, in the EOC question 15 solution, GROWTH is NOT considered in the numerator!
in Q15, the normalized earnings provided are a projection of the forecasted year ahead value, which is what you are looking for (and the practical affect of growing current year normalized earnings).
The numbers are a PROJECTION for following year (so g is already implied). This is btw. a common trap in DDM, FCFE, FCFF etc. as well! Always watch out for the reference year.
