The procedure of voting for a company’s directors; each shareholder is entitled one vote per share times the number of directors to be elected. This is sometimes known as ‘proportional voting’.

A strategy used by corporations to discourage hostile takeovers. With a poison pill, the target company attempts to make its stock less attractive to the acquirer. There are two types of poison pills: 1. A “flip-in” allows existing shareholders (except the acquirer) to buy more shares at a discount. 2. A “flip-over” allows stockholders to buy the acquirer’s shares at a discounted price after the merger. Investopedia explains Poison Pill 1. By purchasing more shares cheaply (flip-in), investors get instant profits and, more importantly, they dilute the shares held by the acquirer. This makes the takeover attempt more difficult and more expensive. 2. An example of a flip-over is when shareholders gain the right to purchase the stock of the acquirer on a two-for-one basis in any subsequent merger.

This results in increased shareholder value. POSION PILL GOOD FOR SHH D.Golden Parachute: What Does Golden Parachute Mean?
