The paper, Why Do Dual-Class Firms Have Staggered Boards?, which was recently made publicly available on SSRN, identifies a relatively high incidence of the combination of two of the strongest anti-takeover mechanisms: a dual-class capital structure with a staggered board. On its face this combination seems superfluous and redundant. If we already have a dual-class capital structure, why do we need a staggered board?
Even more puzzling are the results of the empirical studies of the combined use of staggered boards and dual class capital structures that find a negative correlation between staggered boards and firm value (as measured by Tobin’s Q) similar to the correlation found in firms with single class capital structures. This statistically significant and economically meaningful correlation persists even when controlling for special cases such as founder firms and family firms. Similarly, there are no significant changes in the results when controlling for effective dual class structures, i.e., dual class structures that grant de jure control and not merely the likelihood of de facto control.
