This question calculates the value per share of common stock using the residual income valuation model.
To get to this value, the mock exam answer explains a time-consuming calculation to get each year’s book value. After this is done, you would have to calculate each year’s RI and then utilize the RI value equation.
Is there a quicker way to get this? This problem as explained would require at least 5-10 minutes by itself.
