How debt affects companies is an issue that has received much attention. The fact that researchers disagree can make it hard for companies to choose a financingpolicy that maximizes the value of the firm and its return on equity. In a world with investors that are seeking to maximize profits the value of the firm can be affected differently by different economic conditions. The intention of this study is to answer these issues with quantitive methods, with focus on year 2010 and 2009, where the value of the firm is defined as P/E and P/B ratio. The outcome showed that liabilities only affected return on equity significant in one of four cases, and liabilites didn’t affect the value of companies significantly in any of these. The return on equity did affect the P/B ratio significantly in year 2010, and the P/E ratio in year 2009, but no significance could be shown in the two other cases.
