Accounting Quality and Debt Concentration: Evidence from Internal Control Weakness Disclosures

Abstract

This paper examines how accounting quality affects the degree of debt concentration in corporate capital structures (i.e., a firm’s tendency to predominantly rely on only a few types of debt). Motivated by theoretical and empirical research that supports a strong link between creditors’ coordination costs and debt concentration and the importance of accounting quality in reducing these coordination costs, we hypothesize that firms with low accounting quality have a more concentrated debt structure. Measuring financial reporting quality by the disclosure of material internal control weaknesses over financial reporting (ICWs), we find that ICWs lead to a significantly more concentrated debt structure. We also show that the effect of ICWs on the degree of debt concentration is stronger for more severe ICW disclosures and for firms with a higher credit risk, further reinforcing the importance of financial reporting quality in determining debt concentration.
