This study investigates whether block acquisitions lead to changes in board and CEO compensation characteristics and finds that block purchasers do not play a significant role in improving the firm’s governance practices. However, the majority of professional investors have sold their block within a year, suggesting that they do not own their stock long enough to alter governance policies nor to benefit from such changes. For the smaller number of firms where a new blockholder maintains their investment for more than a year, the use of equity based CEO compensation increases while the use of cash based compensation decreases.
