This document provides data on shareholder proposals, activism, and corporate control measures. It shows that individual investors, social funds, and unions are most active in sponsoring shareholder proposals. Unions tend to sponsor proposals on executive compensation and director elections. Hedge funds commonly seek director or CEO turnover in settlements with companies. While antitakeover protections like poison pills and staggered boards have declined, shareholders can still be rewarded with large takeover premiums in successful mergers and acquisitions. CEOs also often receive large payouts known as "golden parachutes" following a change in control.
