Legislation (eg, California's board racial and ethnic and gender diversity mandates) is not the only route that diversity advocates are employing to diversify the ranks of corporate directors. Moral suasion, together with implicit or explicit voting pressure, is another avenue that some groups are pursuing. One group following this path is the Russell 3000 Board Diversity Disclosure Initiative, which sent a letter to companies on the Russell 3000, urging that they all disclose board racial, ethnic and gender data.
