This paper studies the relationship between corporate leverage and the ultimate corporate ownership structure, particularly the separation of cash flow rights and control rights. We empirically disentangle the three potential effects of the divergence of control rights from cash flow rights on corporate leverage, i.e., the non-dilution entrenchment effect, the bonding role of debt and the fear-of-financial-distress entrenchment effect. Our evidence from the East Asian corporations mainly supports the notion that controlling shareholders with relatively small ownership share tend to increase leverage out of the motive of raising external finance without diluting their shareholding dominance. The separation of cash flow rights and control rights contributes to the risk-taking tendency of the large controlling shareholders in capital structure choice.
