When does an audit stop being optional?

A first-time manager treats the annual audit the way they treat most fixed costs in a young fund: something to defer until the fund can absorb it. An institutional LP treats it the opposite way — as a precondition that has to be satisfied before the conversation about committing capital can start. Neither party is unreasonable. They're operating on different clocks, and most managers don't discover which clock matters until they're already fundraising.

Which LPs actually require it, and why

Pension funds, endowments, and insurers don't require audited financials because they're more skeptical than other allocators. They require them because of their own governance and oversight obligations — a pension answering to trustees and state overseers, an endowment to its board and its own auditors, an insurer to regulatory frameworks that generally require audited statements. The audit requirement is driven by the LP's own governance, not by any distrust of the manager.

Family offices and high-net-worth individuals can invest on unaudited financials and a trusted relationship, because they aren't bound by the same fiduciary architecture. Institutional LPs generally don't have that discretion. It's built into how they're allowed to invest at all.

What happens without one

Audited financial statements are a standard diligence request. If they aren't there, the process stops until they are. The manager scrambles to commission an audit in whatever time remains before the investment committee meets — a timetable few firms can realistically accommodate. The capital commitment that prompted the diligence is now waiting on the document that should have existed before the process began.

The upshot for fund formation

The audit doesn't become mandatory because the fund gets bigger. It becomes mandatory the moment the fund wants to raise from investors who require one.
