The Private Fund Adviser Rule has been the regulatory story that won't end. It passed in 2023, was challenged, was partially vacated by the Fifth Circuit, was the subject of staff guidance through 2025, and is now in a stable-but-fragile state that compliance teams are trying to operate against.
Most of the published commentary is written for lawyers. This is written for the COO, CFO, and CTO who have to translate the lawyers' guidance into operational change.
What Survived the Vacatur
The rule's restrictions on certain side letter terms remain limited but not eliminated. Disclosure obligations around fees and expenses remain enhanced relative to pre-2023 baseline. The quarterly statement requirement and the annual audit requirement for private funds did not survive in their original form, but the SEC has indicated through staff guidance that it expects substantively similar disclosure as a matter of best practice.
The practical effect: most large funds have already operationalized the disclosure regime as if the rule were fully in effect. Smaller funds - sub-$500M - have a closer call.
What This Means for Data Infrastructure
Three things every operations team should be doing in Q2 2026:
1. Standardize the fee and expense allocation methodology and document it. The single most common deficiency we see in mock SEC exams is that the firm cannot explain, with reproducible logic, how a particular expense was allocated to a particular fund or LP. The methodology has to live in code that is reviewable. Spreadsheet-driven allocations are a tail risk.
2. Build the LP-level disclosure pack as a recurring product, not a one-off. Whether the rule's quarterly statement requirement applies to your fund or not, sophisticated LPs are increasingly asking for the same content. Treat it as a standing report. The first one is hard. Every subsequent one should be a one-button operation.
3. Tighten side letter tracking. Most funds maintain a side letter inventory in a Word document or a SharePoint folder. This breaks at scale. We are seeing growing demand for structured side letter data - terms tagged, conflicts flagged, reporting obligations triggered - because manual tracking does not survive an SEC document request well.
What's Still Uncertain
The two issues operators ask us about most:
Cross-fund preferential treatment disclosure. The exact contours of what must be disclosed and when remain unsettled. Counsel guidance varies. Most funds are erring on the side of more disclosure to LPs upfront, fewer disclosures in the marketing deck.
Adviser-led secondary transactions. The fairness opinion requirement and timing of LP notification are still being interpreted. Funds running their first GP-led secondary are paying for clean process documentation; funds that have done several before are mostly waiting for the next round of guidance.
The Operator Read
Compliance is increasingly a data infrastructure question, not a legal question. The legal questions are mostly settled or operational; the gap is between what the lawyers say has to happen and what the systems are actually capable of producing.
Funds that have invested in their data layer in the last 24 months are finding the post-vacatur compliance burden manageable. Funds that have not are finding it acute. The cost gap between the two groups is widening.
This is the practical reason we keep being brought in by the COO rather than by the GC. The legal advice the firm is paying for assumes a data infrastructure that the firm does not have. Closing that gap is the operational program of the next 18 months.
