Prior to this legislation, mergers and acquisitions required a unanimous vote in favor from the shareholders of the company. This allowed for just one dissenting shareholder to veto the merger or acquisition, even though it may have been in the best interest of the company. State legislation took away this right, but in turn, gave the shareholders the right to receive the cash payment for their shares instead.
