Limited partners and their reported performance
Whose numbers these areEach row is the LP’s own number: its cash flows and its valuation policy as of its reporting date, not the fund’s. Net IRR is printed only when the LP prints one. The vintage is the LP’s definition (CalPERS: year of its first cash flow; WSIB: year of its initial investment).1 public LP report

What these amounts and dates areA commitment date prints only when the source printed one; otherwise the row carries the date of the report that listed it. A foundation’s 990-PF line is a holding at fair value on its return, never a commitment.1 relationship, public pensions and the allocator graph, each counted once
