Southeastern Asset Management
http://www.longleafpartners.com/Southeastern Asset Management manages more than $43 billion in assets, including the Longleaf Partners Funds, a group of mutual funds that consistently ranks among the nation's best performers.
Southeastern Asset Management seeks to achieve superior long-term performance by acquiring equity securities of financially strong, well-managed companies run by capable managements at market prices significantly below its assessment of their business value. Southeastern Asset Management sells stocks when they approach their appraisal. Equities purchased at prices substantially less than their intrinsic worth protect capital from significant permanent loss and also appreciate substantially once the market recognizes the company's economic value.
Southeastern Asset Management was founded by Otis "Mason" Hawkins in 1975.
