At this level of shareholdings, the controlling shareholder-and-managers gain significant control over the firm and may utilize this power to divert corporate resources to his own interests. When their ownership is extremely concentrated at higher than 75%, the ownership is positively associated with Tobin’s q. Even though the result is weakly significant at the 13% level, it implies that for managers who own a larger fraction of the firms’ shares, the results of non-value maximization activities will be finally borne by themselves according to the proportion of their stakes. Consequently, the interests of owner managers and outside shareholders converge.
