How to switch fund administrators without missing a quarter

Checked against our editorial standards3 min read

Before you start

Read the exit clause in your current administration agreement. It tells you the notice period, whether there is a termination fee, whether you pay through the notice period, and, if the agreement is well drafted, what the outgoing administrator must hand over and in what format. If it says nothing about handover, assume you will have to ask for everything by name.

Then call the auditor. Not after you have signed with the new provider; before. The transition year is the one where audits go long, and the auditor will tell you which timing they can live with.

Every guide we found on this subject is written by an administrator with a commercial interest in your moving, so the timelines below are their claims. They are consistent enough to plan around.

Step 1. Pick the cutover date

Choose a quarter end, and preferably the one that gives the new administrator a clean start. For a calendar-year fund that means a September 30 cutover so they open the books on October 1 and carry the fund into year end, or a December 31 cutover so the audit works from one set of records. Trident Trust argues for year end. Ocorian argues against, because year end is audit season for everyone. Pick the one your auditor prefers.

Never cut over mid-quarter. The capital accounts have to close on one system and open on the next.

Step 2. Give notice

Written notice, dated, to the contact named in the agreement, with the cutover date and a request for the handover package. Sixty to ninety days is the common requirement. Give it the same day you sign the new engagement so the clocks run together.

Step 3. Define the handover package

Ask for all of it, by name, in machine-readable form:

  • General ledger and trial balance at cutover, and the full transaction history since inception.
  • Capital account statements per LP, every quarter since inception, and the closing balances at cutover.
  • Investment cost basis, valuations and the valuation support.
  • Fee calculations, management fee and carry, with the waterfall logic as applied.
  • Investor records: contacts, commitments, subscription agreements, side letters, tax forms, and the KYC and AML files, which transfer only if your agreement allows it.
  • The document archive: every capital call and distribution notice, quarterly report, K-1 and audit report.
  • Bank statements and reconciliations.

Ocorian's warning is the one to remember: a new provider may want to "draw a line in the sand" and start from the cutover balances without the history. Insist on the history. The auditor and your LPs will.

Step 4. Rebuild and reconcile

The new administrator loads the history and rebuilds the books to cutover. Then three reconciliations: closing capital accounts at the old provider equal opening capital accounts at the new one, per LP, to the cent; the bank balance agrees to the ledger; and the investment schedule agrees to the last quarterly report. FundCore's point is practical: most auditors are not materially affected if the incoming administrator has 60 days to rebuild.

Run one quarter in parallel if you can afford it. Formidium's warning that traditional parallel runs can last six months is a reason to scope the parallel run tightly, not to skip it.

Step 5. Cut over

Transfer capital call authority, portal access and LP communications on the agreed date. Send LPs one note a week before: the date, the new portal, the new contact, what changes for them. Issue nothing from the old provider after cutover. Keep read access to the old portal through the next audit.

Step 6. The transition-year audit

Agree in writing which administrator supports the audit and for which periods. The custody rule still requires audited financials to LPs within 120 days of fiscal year end, or 180 days for a fund of funds under SEC staff relief, and the auditor will not accept "the old administrator has the records" as an answer. NAV states it replicates year-to-date data to support a mid-year audit; ask your new provider for the same commitment in the engagement letter.

The two mistakes that cost a quarter

  • Signing the new provider before reading the old exit clause. The notice period and any termination fee then set your timeline, not you.
  • Accepting cutover balances without history. Every later question from an LP or an auditor about a pre-cutover figure becomes a request to a firm you no longer pay.

Frequently asked questions

How long does it take to switch fund administrators?
The administrators' own guides range from two to four weeks (NAV Fund Services) to 60 to 90 days (FundCore), with a 12-week plan being typical. Formidium notes parallel running in a traditional transition can last six months. Budget a full quarter and be pleased if it takes less.
When is the best time to switch?
At a reporting break, and the sources disagree on which. Trident Trust favours year end so the audit works from one provider's records. Ocorian says avoid audit season and that most migrations happen in the second and third quarters, with Q3 ideal for a calendar-year fund so the new administrator starts the year clean. FundCore says right after Q2 or Q4 reporting. All of them agree: never mid-quarter.
What notice do I have to give?
Whatever your administration agreement says. FundCore reports 60 to 90 days written notice is common and Trident Trust describes 90 days as typical. Some agreements carry termination fees or require payment through the notice period, so read the exit clause before you sign the new engagement.
Who does the audit in the year I switch?
Agree it in writing with both administrators and the auditor before cutover. NAV states it will replicate year-to-date data in its system to support the current-year audit for a mid-year switch; Trident Trust advises agreeing a plan for working with data from both providers. The custody rule still requires audited financials to LPs within 120 days of fiscal year end regardless of who kept the books.
Will LPs notice?
They will notice a new portal login and a new name on notices. Tell them before it happens, in one short note with the date, the new contact and what changes for them. The capital account balance they see on day one at the new provider must equal the last balance from the old one, to the cent.
