The school was renamed in 2008 following a $300 million endowment gift to the school by alumnus David G. Booth. The school has the third-largest endowment of any business school. The school belongs to the M7 group of elite MBA programs which recognize each other as peers, consisting of Chicago Booth, Columbia, Harvard, Kellogg, MIT Sloan, Stanford, and Wharton.
