Ratio analysis Calculate and interpret the following ratios and measures. 1. Measuring ability to pay current liabilities (Liquidity analysis): Calculate the current ratio and the quick ratio the company for the latest year presented. How easily can the company meet their current obligations? 2. Measuring turnover and cash conversion cycle: Evaluate the ability to sell inventory, collect receivables, and manage payments. (Note: You will need to use some balance sheet balances from three years, even though the balance sheet only includes two years of balances. To find one year earlier than the two years presented on the balance sheet, find the Form 10-K for the earlier year.) 3. Measuring leverage (overall ability to pay debts): Calculate the debt ratio and the times- interest-eamed ratio for the latest year presented. How easily can the company meet its long- term obligations? 4. Measuring profitability: - Calculate or list the following ratios for the latest year presented: Gross margin ratio, Operating income ratio, and Earnings per share. How profitable is the company? - Calculate Retum on Assets for the two most recent years. What is the trend? (Note: You will need to use some balance sheet balances from three years, even though the balance sheet only includes two years of balances. To find one year earlier than the two years presented on the balance sheet, find the Form 10-K for the earlier year.) 5. Analyzing stock as an investment: Calculate the following ratios for the latest year presented: Price- earnings ratio and dividend yield ratio.
