Directors\u27 and Officers\u27 Liability Insurance and Acquisition Outcomes

We examine the effect of directors\u27 and officers\u27 liability insurance (D&O insurance) on the outcomes of merger and acquisition (M&A) decisions. We find that acquirers whose executives have a higher level of D&O insurance coverage experience significantly lower announcement-period abnormal stock returns. Further analyses suggest that acquirers with a higher level of D&O insurance protection tend to pay higher acquisition premiums and their acquisitions appear to exhibit lower synergies. The evidence provides support for the notion that the provision of D&O insurance can induce unintended moral hazard by shielding directors and officers from the discipline of shareholder litigation
