In an organization with voting members, the board is accountable to, and might be subordinate to, the organization's full membership, which usually vote for the members of the board. In a stock corporation, non-executive directors are voted for by the shareholders and the board is the highest authority in the management of the corporation. The board of directors appoints the chief executive officer of the corporation and sets out the overall strategic direction. In corporations with dispersed ownership, the identification and nomination of directors (that shareholders vote for or against) are often done by the board itself, leading to a high degree of self-perpetuation. In a non-stock corporation with no general voting membership, the board is the supreme governing body of the institution; its members are sometimes chosen by the board itself.
Other names include board of directors and advisors, board of governors, board of managers, board of regents, board of trustees, or board of visitors. It may also be called "the executive board" and is often simply referred to as "the board".
The legal responsibilities of boards and board members vary with the nature of the organization, and between jurisdictions. For companies with publicly trading stock, these responsibilities are typically much more rigorous and complex than for those of other types.
Typically, the board chooses one of its members to be the chairman (more usually now called the "chair" or "chairperson"), who holds whatever title is specified in the bylaws or articles of association. However, in membership organizations, the members elect the president of the organization and the president becomes the chair of the board, unless the bylaws say otherwise.
