Answer:
2.04 percent
Explanation:
Given that,
ROE = 10 percent
Dividend payout ratio = 80 percent
ROE = Net income ÷ Equity
= 10 percent
Retention Ratio = 1 - Dividend payout ratio
= 1 - 80 percent
= 0.2 or 20%
Therefore,
Sustainable growth rate:
= (ROE × Retention Ratio) ÷ [1 - (ROE × Retention Ratio)]
= (10% × 20%) ÷ [1 - (10% × 20%)]
= 0.02 ÷ (1 - 0.02)
= 0.02 ÷ 0.98
= 0.0204 or 2.04%
