Jonathan Matthews and James Fauset, money managers at Brevan Howard Asset Management, have left the hedge-fund firm, according to a person with knowledge of their departures and records at the U.K.’s Financial Conduct Authority.

Matthews traded equities and foreign exchange in London and had joined Brevan Howard in 2004 from Citigroup Inc., a year after billionaire Alan Howard started the hedge fund. Fauset, a former Goldman Sachs Group Inc. executive, joined the firm in 2011. Both de-registered from the FCA earlier this month. 

A Brevan Howard spokesman declined to comment on the departures as did Matthews. Fauset did not respond to messages left on his LinkedIn profile and couldn’t be reached at Brevan Howard’s offices.

Brevan Howard’s main macro hedge fund posted a record monthly loss in December, triggering a second successive annual decline. The firm has seen its assets drop to less than $25 billion from $40 billion in 2013, though it remains Europe’s largest macro hedge-fund firm.
