Vintage Year

How vintage year works

Vintage year is a label, not a measurement. It exists so that a fund's performance can be compared against funds that faced the same entry prices, the same exit window and the same capital markets.

Cambridge Associates defines it precisely: a vintage year is the legal inception year for a private investment fund, which is not always the year in which the first capital is invested. It adds why the label matters, saying vintage year statistics are critical to assessing an individual fund's performance because they provide a similar universe for comparison.

That definition is worth reading twice, because the common shorthand, that vintage year is the year of the first investment, is a different rule that produces a different answer. A fund that holds a final legal close in December and writes its first check the following March can carry one vintage under an inception-date convention and another under a first-investment convention. Data providers do not all use the same rule, so a fund can appear under two different vintages in two different databases. When comparing, confirm which convention the benchmark uses.

Once a fund has a vintage, it is placed in a peer set and ranked.

Quartile rank = the fund's position in the sorted distribution of net returns for all funds of the same strategy, geography and vintage year

Top-quartile threshold = the net return at the 75th percentile of that peer distribution

Benchmark providers publish more than one summary statistic for each vintage, and they answer different questions. Cambridge Associates describes three: pooled return aggregates all cash flows and ending net asset values in a sample to produce a dollar-weighted return; arithmetic mean averages the individual fund IRRs in a vintage year; median is the middle fund IRR of that group. Because the index is derived from cash flows, the largest funds and largest vintages have the most influence on the pooled figure, which is why a vintage dominated by a few very large funds can look unlike the typical fund in it.

The mechanism behind the whole idea is that entry price and exit conditions are set by the calendar rather than by the manager. A fund that closes at the start of a repricing buys at lower entry multiples and holds through a recovery. A fund that closes at a peak deploys at the highest prices available and often faces a closed exit window when its holdings mature. Both managers may be equally skilled. The reported numbers will not be equal.

Vintage year also interacts with fund age. A 2023-vintage fund compared in 2026 is three years into a ten-year life, sitting in the J-curve, with most of its value unrealized and its quartile rank unstable. Rankings for young vintages move a great deal as marks resolve into cash.

Worked example

Suppose a limited partner is evaluating two US venture funds for a re-up decision. All figures below are hypothetical, used to show the mechanics rather than to report real benchmark levels.

Fund A: legal inception 2015, 150 million dollars in commitments, currently reporting 2.4x net TVPI and 18 percent net IRR since inception, with DPI of 1.5x.

Fund B: legal inception 2021, 150 million dollars in commitments, currently reporting 1.4x net TVPI and 12 percent net IRR since inception, with DPI of 0.1x.

Step one: refuse the direct comparison. Fund A is eleven years old and has returned one and a half times contributed capital in cash. Fund B is five years old and has returned almost nothing. Their reported numbers are not measuring the same thing.

Step two: place each in its vintage peer set. Suppose the benchmark book for US venture reports, for the 2015 vintage, a median net IRR of 14 percent and a top-quartile break at 22 percent; and for the 2021 vintage, a median net IRR of 6 percent and a top-quartile break at 13 percent. These are illustrative figures.

Step three: rank within vintage. Fund A's 18 percent is above the 2015 median but below the top-quartile break: second quartile. Fund B's 12 percent is well above the 2021 median and just under that vintage's top-quartile break: high second quartile, close to first.

Step four: notice the inversion. On raw numbers Fund A looks decisively better. Against peers who faced the same entry prices and the same exit window, the two managers rank similarly, and Fund B is arguably outperforming its cohort by more.

Step five: discount Fund B's rank for age. With a DPI of 0.1x, almost all of Fund B's reported performance is unrealized value struck by the manager. Its quartile position is a statement about current marks, and marks move. Fund A's rank is far more settled because most of its value is already cash.

Where it shows up

In benchmark books and index reports, vintage year is the row label. Cambridge Associates publishes pooled, mean, median and quartile statistics by vintage for US private equity and US venture capital, derived from quarterly unaudited and annual audited partnership financial statements provided by managers, and describes fund-level returns in those books as net of fees, expenses and carried interest.

In a private placement memorandum's track record table, prior funds are listed by vintage year with committed capital, DPI, TVPI and net IRR, and usually a quartile or benchmark comparison for each. That table is where a manager's claim of top-quartile performance is made, and the vintage column is what makes the claim checkable.

In a limited partner's portfolio construction and pacing model, vintage year is the diversification axis. A commitment plan sets a target amount to commit each year specifically so that the portfolio is not concentrated in any single entry environment. Vintage diversification is the private markets equivalent of not buying the whole position on one day.

In the limited partnership agreement, the term vintage year usually does not appear. What appears are the initial closing date, the final closing date and the investment period, and those dates are what a provider maps to a vintage. The label is applied from outside the document.

In marketing materials, the Securities and Exchange Commission's marketing rule governs how the related performance in that track record table can be shown, including the requirement that gross performance be accompanied by net performance with equal prominence over the same period.

Common mistakes

• Comparing funds across vintages. This is the error the label exists to prevent, and it happens constantly in fundraising decks and press coverage.
• Assuming vintage means the year of the first investment. Cambridge Associates uses legal inception, which is often a different year, and providers differ.
• Ranking a young vintage as if it were settled. Early quartile positions are driven by unrealized marks and shift materially as holdings realize.
• Reading a strong vintage as a strong manager. Entry environment explains a large share of dispersion between vintages; skill shows up as rank within a vintage.
• Mixing statistics. A fund can beat the median and lose to the pooled return in the same vintage, because pooled returns are dollar-weighted and dominated by the largest funds.
• Ignoring the peer set definition. Same vintage, different strategy or geography, is still the wrong comparison.
• Forgetting survivorship and self-selection. Benchmark datasets are built from managers who report, and a manager that stopped reporting stops appearing.

Related terms

Vintage year is the frame inside which IRR, TVPI, DPI and MOIC become comparable, and it explains why an early J-curve reading should not be ranked against a mature fund. It is central to how a limited partner builds a commitment program, and it is one of the main reasons private equity and venture capital benchmarks are reported separately rather than blended.

Frequently asked questions

What is a vintage year in private equity?

It is the year assigned to a fund for benchmarking, so that its performance is compared only with funds that began investing in the same environment. Cambridge Associates defines it as the fund's legal inception year, which is not necessarily the year the first capital was invested. Every quartile ranking and benchmark comparison in private markets is calculated within a vintage.

How is a fund's vintage year determined?

By the convention of whoever is doing the benchmarking. Cambridge Associates uses legal inception. Other providers and managers use the date of the first capital call or the first portfolio investment. The rules can produce different years for the same fund, particularly for funds that close late in a calendar year, so the convention should be confirmed before comparing.

Why does vintage year matter so much?

Because entry pricing, competition for deals and the exit window available to a fund are largely set by when it deploys, not by who manages it. Two managers of equal ability investing three years apart will report very different numbers. Comparing within a vintage strips out the part of the result that was determined by the calendar and leaves the part attributable to the manager.

What is a top-quartile fund?

A fund whose net return places it in the best 25 percent of its vintage and strategy peer group. The claim is only meaningful with three qualifiers attached: which metric, which peer universe, and as of what date. A fund can be top quartile on IRR and second quartile on TVPI, or top quartile in one provider's dataset and not in another's.

Can a fund change vintage years?

Not normally once assigned, though a fund's vintage can be recorded differently by different data providers from the outset, and a manager can present a different year in its own materials than a benchmark provider uses. Extended fundraising periods are the usual cause, where the first close and the final close fall in different calendar years.

How many vintage years should a limited partner spread commitments across?

There is no fixed answer, and it depends on the size of the program and the pace at which capital returns. The principle is that committing the whole allocation in one or two years concentrates the portfolio in one entry environment, so institutional programs typically commit a planned amount every year across a full market cycle rather than timing entry.
