The empirical part of the study reveals that the leverage ratios defined in short-term debts, long-term debts, total debts and book value of assets are correlated. Similarly, the leverage ratios defined in short-term debts, long-term debts, total debts and market value of assets are correlated. However, book value based and market value based leverage ratios are not correlated. The leverage ratios defined in earnings before interest and taxes over interest and earnings before interest, taxes and depreciation over interest are positively perfectly correlated. Besides, short-term loans are three times more compare to long term debts, firms are reluctant in paying tax and allotment in research and development expenses are insufficient. In addition, industry median average, non-debts tax shield, uniqueness (R&D) positively significantly affects financial leverage and, and size, tangibility, tax rate, dividend pay-out, agency cost, business risk, GDP growth, and money growth negatively significantly affects financial leverage.
