Answer: 75%
Explanation:
The fraction of earnings that CCN must be plowing back into the company goes thus:
Growth rate = 9%
Discount rate = 12%
Expected dividend per year = $0.50
Return on equity = 12%
It should be noted that:
Growth rate = plowback ratio × Return on equity
9% = plowback ratio × 12%
Therefore, plowback ratio = 9% / 12%
Plowback ratio = 75%
Therefore, fraction of earnings must CCN be plowing back into the company is 75%.
