Public data published by the US Securities and Exchange Commission (US government work). Advisers report these values themselves in Form ADV, and neither the SEC nor the states approve or guarantee them. AUM is regulatory assets under management as the adviser reported it in Form ADV item 5.F, which can differ from the AUM a firm quotes elsewhere. Exempt reporting advisers do not report AUM. Office address, phone and website are the adviser's main office as filed; a firm that files its main office as a private residence shows no street address or phone. An Item 11 disclosure is a reported event, not a finding about the firm today. Details for each firm are on the SEC's Investment Adviser Public Disclosure site.
