Sources and method

  • Form ADV Part 1A, Schedule D, Section 7.B.(1), as filed by each adviser with the SEC (IARD) and rendered on IAPD; current Form ADV filings read October 2026. Questions 23 to 28 name the fund's auditor, prime brokers, custodians, administrators and marketers.
  • One record per firm: legal names grouped by a normalized form and by AltStreet's alias table for brands whose entities do not share one. Grouping errors can be reported through the contact page; the filed names are listed above so the grouping can be checked.
  • Gross asset value is Schedule D question 11 for each fund, summed once per fund across the firm's roles; it is the funds' stated value, not assets under the firm's administration or custody.
  • The page records what advisers disclosed. It is not an assessment of the firm, and the firm did not provide or review it.
