A high debt-to-equity ratio can present challenges in the face of falling revenue, which most U.S. oil producers experienced in 2015 because of lower oil prices. A company agrees to the terms of a bank loan or bond issuance to fund projects with the expectation that its activities will generate sufficient revenue to service the debt and eventually repay it. Debt on the balance sheet implies future cash outflows. The need to service large amounts of debt as revenues declined made companies with high debt-to-equity ratios more vulnerable to losses than companies with less leverage in their capital structures.
