Grumbling over overregulation aside, a good number of the biggest European hedge funds appear to have accepted the U.S. Securities and Exchange Commission requirement that HF advisers register, the Financial Times reports. All this information is available from the SEC web site, where the required Form ADV is posted. Perhaps the most interesting entry on the form is Item 5-F, which states a firm's total assets and number of accounts. Among the big names on the SEC database are Bluecrest Capital Management (US$6.666 billion AUM, 20 accounts), Brevan Howard Asset Management (US$8.6 billion, 2), Cheyne Capital Management (US$24.9 billion, 5), The Children's Investment Fund (US$6.9 billion, 5), CQS (US$4.5 billion, 6), Marshall Wace (US$6.1 billion, 9) and Sloane Robinson (US$7.9 billion, 9). Still missing in action, says FT, is GLG Partners, which currently has its hands full with an investigation by the U.K. Financial Services Authority. Meanwhile, the FSA says it will work closely with the SEC to "minimize the impact on U.K.-regulated firms, noting that the SEC said it would alert it before any inspections of a U.K. firm.
