F. William McNabb III is chairman and chief executive officer of Vanguard. He joined Vanguard in 1986, took on the role of chief executive officer in 2008, and became chairman of the board of directors and the boards of trustees in 2010.
Let's start by noting a fundamental difference between these two companies. Vanguard is actually owned by the shareholders of its mutual funds. If the company is profitable (and it is), those profits go to the people who own Vanguard funds, not to outside investors. This is an unusual business model, similar in some ways to that of credit unions and other cooperatives that ultimately operate for the benefit of their customer-members.
