As of May 2015, based on trailing 12-month data, the average long-term debt/equity ratio of airline companies is 91.53. Airline companies are included in the major airlines and regional airlines subsectors, which are a part of the transportation sector.
The debt/equity ratio measures a company's financial stability and leverage and is calculated by dividing a company's total liabilities by its shareholders' equity. If a company has a high debt/equity ratio, it typically indicates that the company has a high debt level per each dollar of shareholders' equity. Therefore, investors favor companies with low debt/equity ratios.
The average long-term debt/equity ratio of companies in the major airline industry is 104.89, which indicates that for every $1 of shareholders' equity, the average company in the industry has $104.89 in total liabilities. Since the major airline industry is highly capital-intensive, companies in this industry tend to have high debt/equity ratios.
Similarly, the average long-term debt/equity ratio of companies in the regional airline industry is 78.16, indicating that the average company in the regional airline industry has $78.16 in debt per $1 of shareholders' equity.
