In practice
Equalization is set out in the LPA and handled by the administrator at each subsequent close. The later investor’s payment is usually distributed to earlier investors, and sometimes partly to the fund, rather than kept by the GP. The interest rate varies, often a stated rate or a benchmark plus a spread. Not to be confused with a subscription line, which delays calls, or with fee step-downs.
An example
Round numbers, not a real fundSay an investor joins a fund at its second close, 6 months after the first. It pays its share of earlier calls and fees, plus interest, so it ends up level with first-close investors.
Why it matters
It is why late investors do not get a free ride on early deals, and why later closes can mean a surprise payment.
