Alaska Permanent Fund Corporation (APFC): APFC Private Equity Report: Private Equity Fund Commitments & Direct Investments / Co-Investments, as of December 31, 2025. APFC's quarterly Private Equity report ("Private Equity Fund Commitments & Direct Investments / Co-Investments") lists each fund with only its currency, "Vintage Year" and "Commitment (USD)", shown here in whole US dollars as printed. It reports no contributions, distributions, market value, multiple or IRR per fund, so paid-in, distributed, total value, IRR, TVPI and DPI are blank; nothing is derived or estimated. All 454 entries of the report's "Fund Investments" list are included ($17,570,561,197 committed); 15 have the vintage year "TBD" (blank here) and 45 are commitments in another currency that APFC states in US dollars. The report's separate "Direct Investments / Co-Investments" list (56 entries, $2,792,151,600: portfolio companies, co-investment vehicles and manager stakes) is not imported. The two lists add up to the report's printed Total Commitments of $20,362,712,795. For the whole portfolio, including liquidated investments, the report prints Cumulative Contributions of $20,951,089,446, Cumulative Distributions of $22,493,801,627 and a Remaining Fair Market Value of $15,555,575,745. APFC is a state-owned corporation that manages the Alaska Permanent Fund, not a pension plan; its separate Private Income report is not imported. View source

UTIMCO (Permanent University Fund): Permanent University Fund Detail Schedules of Investment Securities, Schedule H: Private Investment Funds, as of August 31, 2025. Holdings only: the audited Schedule H lists each private investment fund held by the Permanent University Fund, which UTIMCO manages, with its fair value at the August 31 fiscal year end and nothing else, so vintage year, commitment, contributions, distributions, total value, IRR and multiples are blank (UTIMCO reports none of them here); each fund's fair value is kept as market_value_usd in whole dollars as printed. Fund names are as printed (capitals, abbreviated). Included are the schedule's Private Equity (159 funds), Venture (165) and Emerging Market Equity (29) sections; its Credit, Infrastructure, Natural Resources and Real Estate sections are not imported, and neither are 24 direct investments in the imported sections, which UTIMCO lists only as numbered "Direct Investment" rows because their names are confidential under Texas Government Code 552.143(c). Covers the Permanent University Fund only: UTIMCO publishes no such schedule for the General Endowment Fund, and it provides its fund-level Private Markets performance reports only in answer to an open records request.
