Grouped from Form D issuer names (generation, sleeve, jurisdiction and legal-form tokens removed); a name-only match, so abbreviated or renamed vehicles can be missed. Sold and investor figures are each vehicle's latest Form D; sleeves that report the same figure share one family-wide total and are counted once. Performance lines are what a public pension plan reports for its own interest in that fund, net, on the plan's cash flows and valuation date; they are not the general partner's figures.
