Step 1: What decides the better return here.
To see which company rewards its shareholders better, we compare Earnings Per Share (EPS), and the concept behind the comparison is trading on equity, using fixed cost debt to boost equity returns when the return earned on capital is higher than the interest paid on that debt.
Step 2: Working out profit after interest and tax.
Capital employed is Rupees 20,00,000 for both firms and ROI is 10 percent, so EBIT for both = 2,00,000. Ratan Ltd, being all equity financed, has no interest to pay, so its EBT stays at 2,00,000; tax at 40 percent = 80,000, leaving EAT of 1,20,000. Lara Ltd has 8,00,000 as 8 percent debentures, so interest = 64,000; EBT becomes 1,36,000, tax at 40 percent = 54,400, leaving EAT of 81,600.
Step 3: Converting profit into EPS.
Ratan Ltd has 20,000 equity shares of Rupees 100 each (since its full 20,00,000 came from shares), giving EPS = 1,20,000 divided by 20,000 = Rupees 6. Lara Ltd has only 12,000 equity shares of Rupees 100 each (60 percent of 20,00,000), giving EPS = 81,600 divided by 12,000 = Rupees 6.8.
Final answer: Option 2, Lara Ltd. will give a higher EPS, because its ROI of 10 percent exceeds the 8 percent cost of debt, so trading on equity works in its favour.
