In 2003, Hohn set up his own hedge fund, The Children's Investment Fund. TCI donated regularly to a connected charitable fund, The Children's Investment Fund Foundation, run by his wife. The original formula involved transfers of 0.5 percent of the fund's assets each year, with a further 0.5 per cent of assets for every year during which the fund achieved returns of more than 11 per cent. It is reported that Hohn established the formulaic charitable link in order to motivate himself. More recently, in March 2013, TCI announced that it would stop donating to the foundation because it is "large enough."
