Directors at David Harding’s Winton Capital Group hedge fund shared dividends totaling 311 million pounds ($453 million) for 2015 after the payout was boosted by 145 percent from a year earlier as assets under management rose.

The firm’s 11 directors also received a total of 23.1 million pounds in pay, with the best rewarded receiving 11 million pounds, according to accounts filed by the quantitative hedge fund manager in London. Dividends for one of the directors was paid to a family trust, the filing published on Thursday shows. A spokesman for London-based Winton declined to identify the highest-paid director and to comment on the accounts.

Harding owns about 54 percent of the hedge fund’s total shares, according to a separate filing by the firm in October. Assets overseen by the firm increased to $33.8 billion from $28.4 billion a year earlier as investor inflows rose and trading performance was positive, according to the accounts. The company’s headcount rose to 420 from 339, and a further increase is planned this year, the filing shows.

The group received a dividend of 125 million pounds from its Winton Capital Management unit in March.

Harding founded Winton Capital in 1997. He has given at least $5.1 million to a group campaigning for the U.K. to remain part of the European Union in the June 23 referendum on membership of the 28-member bloc.
