The Impact of Hedge Fund Activism on the Target Firm's Existing Bondholders

In contrast to previous studies documenting positive abnormal returns to target shareholders, we find that hedge fund activism significantly reduces existing bondholders' wealth. Bondholders earn an average excess bond return of -3.9% around the initial 13D filing date, and an additional average excess bond return of -6.4% over the remaining year after the filing date. When examining the reasons behind these results, we find that negative excess bond returns are related to a subsequent decline in cash on hand (loss of collateral effects) and an increase in total debt as a percentage of total assets. In addition, negative bond returns are more prominent when the hedge fund activist conducts a confrontational campaign against the target firm or if the activist gains at least one seat on the target's board within a year of the initial 13D filing. We also find evidence of an expropriation of wealth from the bondholder to the shareholder. We conclude that the intervention of the activist results in the firm taking actions that are deleterious to bondholder wealth
