    Reporting integrity and period locking

    Investor reporting has one property that ordinary software rarely provides: once a number has been sent to an investor, it is a historical fact, and changing it quietly is a governance failure rather than an edit.

    Short answer

    What is period locking in fund reporting?

    Period locking means that once a reporting period is closed, its figures cannot be silently changed. Any later correction is recorded as a restatement, with the original figure, the new figure, the reason and the date all kept. This is what allows a manager to explain, two years later, exactly what was reported and why it changed.

    Why a spreadsheet cannot do this

    A spreadsheet has no memory of what it said last quarter. If a valuation is revised, the cell changes, and the only evidence of the old number is a file called final version three.

    That is fine until somebody asks why an investor's statement from eighteen months ago does not match the current model. At that point you need the original, the change and the reason, and you need them without a forensic exercise.

    • The number as reported, with its date.
    • The number now, and what changed it.
    • Who made the change and when.
    • Whether investors were told, and how.

    Restatements, done properly

    A restatement is not an admission of failure. Valuations get revised, an audit finds an adjustment, a late expense lands. The failure is doing it silently.

    A clean restatement trail is also the fastest way through an audit, because the auditor's usual question is not what the number is, but how it moved.

    How this runs in Reuben AI

    The Reporting Hub holds an overview, a custom report builder and a reporting integrity view. Closing a period locks it.

    After a lock, changes are recorded as restatements with a visible trail, so both the original and the corrected figure remain available and the reason sits with them.

    Because investor reports are generated from the same records, a report can be traced back to the version of the numbers it was issued on rather than to whatever the model says today.

    Audit packs and accountant export packs, single fund or consolidated, are produced from the same source, which is what shortens the quarter end handoff.

    What stays off the platform

    Being honest about the boundary is more useful than claiming everything. Reuben AI is not an auditor, a law firm, a tax agent, a bank or a licensed administrator, and it does not sign anything that those roles have to sign.

    What the platform does is hold the records those people need in a form they can accept, and produce the packs on request rather than at the end of a two week scramble.

    • Audit opinion and assurance work: your auditor.
    • Fund formation documents and legal advice: your counsel.
    • Tax filings and returns: your tax adviser.
    • Holding client money and moving it: your bank and payment providers.
    • Licensed administration or trustee duties where local rules require a licence: your administrator or trustee.

    Common questions

    Can a locked period be reopened?
    Corrections after a lock are handled as restatements with a recorded reason and trail rather than as a silent edit, so the reported history stays intact.
    Does this replace an audit?
    No. It makes the audit faster by giving the auditor the movement history they would otherwise have to reconstruct. The opinion remains the auditor's.
    What is in an audit pack?
    The records the fund ran on for the period, exported in a structured form, alongside the accountant export packs for single or consolidated funds.
