In practice
Vintage is used in benchmarking and in LP portfolio reporting, where commitments are grouped by year to spread exposure across market cycles. Definitions vary: some data providers use the first close, the first capital call or the first investment, so the same fund can carry different vintages in different databases. It is not the fund’s formation date or its closing year.
An example
Round numbers, not a real fundSay two funds both started in 2019. Their returns are compared with each other and with other 2019 funds, not with a fund that began after a market crash.
Why it matters
Funds that invested in the same market conditions are the fair comparison, so vintage shapes how a fund is ranked.
A definition, not advice; where usage varies the entry says so. Something wrong? Tell the desk.
