Abstract (EN)

Having been introduced in the European Union and in many other countries, the equal opportunity rule is seen as protecting investors in the event of a transfer of control. This rule should be analyzed in a context of appropriation of private benefits between the new controlling shareholders and the outside investors. Both parties need to design a new implicit contract to share the firm's ownership. Using a signaling model, we show that the new controlling shareholder issues signals to outside shareholders to deliver private information on a firm's future economic return and her private rate of appropriation. The ownership stake of the controlling shareholder and the premium embedded in the acquisition price are key parameters. In a controlling ownership system, the equal opportunity rule modifies the relative behavior of controlling and outside shareholders. The quality of information deteriorates but the discipline on appropriation may become stronger.
