Leverage refers to the use of debt to finance assets or operations. It allows for greater potential returns but also greater potential losses if the investment becomes worthless and loan obligations must still be repaid. The degree of financial leverage is measured by the percentage change in earnings per share from a given percentage change in earnings before interest and taxes. Leverage can be measured using ratios like debt-to-equity and debt-to-capital. Cash flow information is important for a company's ability to meet fixed obligations but does not indicate future risk on its own.
