The duties of presidents of corporations vary greatly. In some corporations, the president is the active executive head with supervision of entire business of the company, while in others he is little more than the presiding officer of the board of directors. In large corporations the president is assisted by several vice-presidents among whom a large portion of the executive duties are divided. There are also, frequently a chairman, of the board of directors, and a chairman of the finance committee.
