The Children's Investment Fund Management

The Children's Investment Fund Management (UK) LLP (TCI) is a London‐based hedge fund management firm founded by Chris Hohn in 2003 which manages the Children's Investment Master Fund. TCI makes long‐term investments in companies globally. The management company is authorized and regulated in the United Kingdom by the Financial Conduct Authority. Its holding company is TCI Fund Management Limited, based in the Cayman Islands. TCI derives its name from a charitable foundation called the Children's Investment Fund Foundation (CIFF), set up by Chris Hohn and his ex-wife, Jamie Cooper-Hohn, and initially contributed a proportion of profits to the foundation. In January 2022, TCI was named by the Guardian as the world's top-performing hedge fund. It is known as one of the most aggressive activist investors. Like most hedge funds, TCI requires investors to commit their capital for multi-year periods. This long-term horizon allows the fund greater flexibility when trading and investing capital independent of any potential ad hoc time constraints. Charity TCI derives its name from the Children's Investment Fund Foundation (CIFF), a charitable foundation set up by Chris Hohn and his ex-wife, Jamie Cooper-Hohn. In an example of "venture philanthropy", CIFF initially received a portion of TCI's profits and other donations. CIFF focuses on improving the lives of children living in poverty in developing countries, and has grown to be one of the largest charities in the United Kingdom. After suffering a 43% loss during the 2008 calendar year, as of July 2009 the previous financial year had seen a rebound of over 70% profit and revenue for TCI.
