Directors’ and officers’ liability insurance and the cost of equity

Abstract

We examine whether directors׳ and officers׳ (D&O) liability insurance affects a firm’s cost of equity. We find a positive association between D&O insurance and the cost of equity. Information quality and risk-taking appear to be two underlying channels through which D&O insurance affects the cost of equity. Further tests suggest that this positive association is not due to optimal risk-taking, as evidenced by a negative market reaction to an increase in D&O insurance coverage, a lack of improvement in firms׳ cash flow and a low valuation associated with high D&O insurance. Overall, our evidence is consistent with the notion that D&O insurance weakens the disciplining effect of shareholder litigation, leading to an increase in the cost of equity.
