Debt structure : a solution to the puzzle of capital structure

Purpose: The purpose of this paper is to investigate the relation between debt structure and future external financing and investment. Furthermore, it aims to analyze the association between debt structure and future financial performance. Design/methodology/approach: Volume, maturity, possessing collateral and having priority at the settlement date are the dimensions of debt structure that have been employed in this paper. The sample consists of 1,060 firm-year observations from Tehran Stock Exchange corporations during the period 2009–2018. Findings: The findings reveal that greater reliance on financial leverage (debt volume) and short-term debt are associated with increases in future debt financing as well as future equity financing. Moreover, these two dimensions of debt structure are positively related to future investment. This paper also shows that the positive impact of financial leverage and short-term debt on future financing and investment can finally lead to a favorable financial performance. Regarding other dimensions of debt structure, the results suggest that although collateralized debt with the priority option at the settlement date enhances future external financing, this type of debt can ultimately lead to a reduction in future investment and financial performance. Finally, the findings indicate that uncollateralized debt exacerbates future financial performance. Research limitations/implications: Financial performance can be affected by several factors, including available funds, investment amount, investment efficiency and managerial capability. However, this paper only considers the investment amount and external financing as the channels through which debt structure improves future financial performance. This study has the potential to contribute to one of the most important issues in finance and business fields, despite its probable trivial drawbacks. Practical implications: Financing strategies as one of the most controversial topics have been meticulously scrutinized in this paper and practical implications are made to facilitate the process of decision-making regarding the optimal type of debt financing. Originality/value: This study extends the literature by analyzing the direct link between debt structure and firm performance in firms domiciled in developing markets.
