Step-by-step explanation:
Ratios that measure a firm's financial leverage are known as long-term solvency ratios. These ratios are used to assess a firm's ability to meet its long-term obligations and can be indicative of the level of risk the firm is taking on through its use of debt. The most common long-term solvency ratios include the debt-to-equity ratio, the debt ratio, and the interest coverage ratio. These ratios help investors and creditors understand the long-term financial stability of a company.
