Final answer:
Using the DuPont equation, Harrington Inc.'s ROE is calculated to be approximately 13.7%, which is found by multiplying the company's profit margin (0.058), total asset turnover (1.3), and equity multiplier (1.8182).
Step-by-step explanation:
The DuPont equation is a formula that calculates a company's return on equity (ROE) by multiplying three financial ratios: profit margin, total asset turnover, and the equity multiplier. Given Harrington Inc.'s financial details, we can calculate each ratio:
Profit margin = Net Income / Sales = $19,000 / $325,000 = 0.058,
Total asset turnover = Sales / Total Assets = $325,000 / $250,000 = 1.3,
Total-debt-to-total-capital ratio = 45%, which implies an equity ratio of 55% because the firm uses only debt and equity to finance its assets. Therefore, Total equity / Total assets = 55%, or Total assets / Total equity = 1 / 0.55 = 1.8182.
Now, we apply these figures to the DuPont equation:
ROE = Profit Margin × Total Asset Turnover × Equity Multiplier
ROE = 0.058 × 1.3 × 1.8182 ≈ 0.137 or 13.7%
Therefore, based on the DuPont equation, Harrington Inc.'s ROE is approximately 13.7%.
