The Consequences to Directors for Deploying Poison Pills
Abstract
Using director-specific, within-firm variation in poison pills, we find that pill-adopting non-executive directors experience a decrease in shareholder votes, an increase in termination rates across all their directorships, and a decrease in the likelihood of new board appointments. These consequences are not due to poor firm performance, active bid resistance, or hedge fund activism, and accrue especially when the adopted pill is relatively costly to the firm. Firms have positive stock price reactions when pill-associated directors die unexpectedly, compared to negative returns for other directors. We conclude that pill-adopting directors experience a decrease in the value of their services.
