Proxy voting is a form of voting whereby some members of a decision-making body may delegate their voting power to other members of the same body to vote in their absence, and/or to select additional representatives. A person so designated is called a "proxy" and the person designating him or her is called a "principal". Proxy appointments can be used to form a voting bloc that can exercise greater influence in deliberations or negotiations. Proxy voting is a particularly important practice with respect to corporations; in the United States, investment advisers often vote proxies on behalf of their client accounts.
