About this data
Holdings as this foundation lists them on its Form 990-PF (Part II, lines 13 and 15). Amounts are year-end fair market value, or book value where it gives no other, not commitments or returns. As of December 31, 2025; new holdings are those not on its return for the year ending December 31, 2024. Source: IRS Form 990-PF. Funds are linked to a manager by name; a match can be wrong, and the original filing is the record. How Hottub reads its sources.
