Answer:
a. 5.37%
b. Option A
Step-by-step explanation:
a). ROE = (Sales / Total Assets) *(Net income / Sales) * (Assets/ Equity)
= ($90,000,000 / $150,000,000) * ($10,000,000 / $90,000,000) = 0.0667, or 6.67%
Dividend Rate = Dividend / Net Income = $1,950,000 / $10,000,000 = 0.195, or 19.50%
Retention ratio = (1 - Dividend rate) = 1 - 0.195 = 0.805, or 80.50%
Sustainable growth rate = ROE * Earnings retention ratio
= 6.67% * 0.805 = 5.37%
b). Option "A" is correct.
To maintain a sustainable growth model, one of the assumptions of the model is that proportion of sales and assets remains stable.
Other assumptions are, the firm should maintain a constant net profit margin in proportion to sales achieved, and the capital structure and dividend pay out ratio remains the same.
