Key Takeaways
- • Cambridge Associates defines a fund's vintage year as the year of its first cash flow, the first LP capital call, and fund selectors must confirm which convention a data source uses before benchmarking a fund against its cohort.
- • According to DealEdge data cited by Advisor Perspectives, median buyout IRR rose from 11% in 2000 to 25%, 40% and 47% in the following three years, and from 9% in 2007-2008 to 24%, 18% and 19% after the global financial crisis.
- • A Commonfund (2025) study of the 2000-2020 cohort found that avoiding the three worst buyout and growth equity vintages would have yielded only a marginal performance improvement, making manager selection the more significant lever.
- • In venture capital, the top-to-bottom quartile spread exceeds 30 percentage points in most vintages, roughly three times wider than in buyout, per Cambridge Associates (2025).
- • Commitment pacing across several subsequent vintages is presented as the practical response to vintage dispersion, rather than attempting to predict the best vintage.
Summary
The vintage year determines the cohort against which a private equity fund's IRR is measured, and therefore how that IRR should be interpreted. Cambridge Associates defines the vintage as the year of a fund's first cash flow, meaning the first capital call from limited partners. Other databases use the year of legal inception of the vehicle, which can precede the first drawdown by one or two years. According to the article, that difference can place two funds labeled "vintage 2019" in different market phases with different entry multiples, so verifying the data convention is the first step in due diligence.
The article argues that vintage conditions the macro and pricing environment in which a fund invests and exits. Citing DealEdge data as reported by Advisor Perspectives (2025), it notes that median buyout IRRs were 11% in 2000 before the tech bubble burst and then rose to 25%, 40% and 47% over the following three years. A similar pattern followed the global financial crisis, with median IRR at 9% in 2007-2008 and 24%, 18% and 19% in the subsequent three years. Institutional LPs often label post-correction vintages "opportunity vintages" for this reason.
The article stresses, however, that vintage alone is not the dominant driver. A Commonfund (2025) study of the 2000-2020 cohort found that even perfect timing in avoiding the three worst buyout and growth equity vintages would have produced only a marginal improvement. Manager selection remains the larger lever. Cambridge Associates (2025) data cited in the article show venture capital top-to-bottom quartile spreads above 30 percentage points in most vintages, about three times wider than in buyout. In buyout, the median premium over public markets has compressed from a historical 200-400 basis points to 100-200 basis points in the most recent five-year period.
On cash flows, the article notes that each vintage passes through a J-curve in which capital calls initially exceed distributions. Secondary strategies are described as a way for institutional allocators to shorten this effect, with distributions typically starting one to three years earlier than primary commitments, NAV discounts of roughly 5-20%, and immediate diversification across vintages and GPs (PitchBook, 2025). The article recommends a commitment pacing program that allocates capital regularly across several vintages, cautioning that overly conservative pacing causes structural under-allocation while overly aggressive pacing creates liquidity risk in stress periods.
The article also addresses the 2022-2023 vintages, which it says are drawing attention because the rate-hike cycle slowed LP distributions and shifted re-up discussions toward DPI rather than TVPI. Cambridge Associates data cited in the piece put median US DPI for 2012-2015 buyout vintages at 1.4x to 1.7x as of Q3 2024, and LPs generally expect at least 1.5x DPI by the eighth year for buyout funds. Some institutional allocators view the 2022-2023 cohorts as potentially favorable on a historical basis, though the article emphasizes that confirmation will only come once those funds reach harvesting.
