Despite the importance of CEO succession planning, firms do not typically disclose much information regarding their CEO succession plans due to fear of incurring proprietary costs. Building on screening theory and the skills based model of leadership, however, I theorize that firm stakeholders may screen firms quarterly earnings calls for signals related to three important CEO succession plan detailswhether the firm intends to promote an insider or outsider to CEO, when CEO succession will occur, and who might take over. Specifically, I argue that executive participation on quarterly earnings calls, as well as changes in executive participation on these calls over time, is related to the aforementioned outcomes. In addition, I also theorize that quarterly earnings call experience prior to becoming CEO impacts financial analysts reactions to CEO succession announcements and that newly appointed CEOs with conference call experience will receive more favorable evaluations from analysts during the early stages of their tenure as CEO.
