. This is especially likely given that only 7% of surveyed directors indicated that their company had term limits for board members. Nevertheless, 60% of U.S. boards and 58% of European boards have a mandatory retirement age typically around 70. Research reveals that boards rated as least effective by the Corporate Library, a corporate governance research firm, tend to have members serving longer (an average of 9.7 years) than boards rated as most effective (7.5 years). Directors selected by the CEO often feel that they should go along with any proposal the CEO makes. Thus board members find themselves accountable to the very management they are charged to oversee. Because this is likely to happen, more boards are using a nominating committee to nominate new outside board members for the shareholders to elect. Ninety-even percent of large U.S. corporations now use nominating committees to identify potential directors. This practice is less common in Europe where 60% of boards use nominating committees.
