Account reconciliation

trading accounts carries the account code, custodian, external account ID, currency, owner counterparty and active flag. position snapshots keeps dated provider ledger and available balances for the account. reconciliation items records provider events, occurrence dates, amounts and matching state. Together they let the team explain a provider movement against a confirmed instruction.

• Record. A match requires the exact requested amount, a confirmed occurrence date and the same linked account. An item with a different amount or date remains Unmatched or becomes Exception. The team uses the dated snapshot as the balance source and reviews signed confirmed movements against it.
• Decision. Agree the provider statement format, date basis and treatment of corrections before a pilot. Verify that account identifiers are stable across imported snapshots and movement items. Assign a reviewer to resolve exceptions and retain the event reference used for each conclusion.
• Evidence. Keep the provider event ID, dated snapshot and linked instruction available when a reviewer explains the matched state or an exception.

Agree the provider statement format, the date that controls matching and the treatment of corrections. Check that each external account ID maps to the intended trading account before importing movements. Give the Independent Finance Reviewer a dated provider sample with an event that matches exactly and another with a different date. Decide who investigates an exception and where the provider clarification is retained. The balance snapshot should carry its as-of date; do not use a later balance to explain an earlier movement without showing the intervening events.

A provider item shows the same amount as an instruction but a different occurrence date. The item stays Unmatched or Exception while the reviewer checks the source statement; it is not marked Matched just because the amount agrees. Another item with the right date but a different account also needs investigation. At handoff, the reviewer opens the provider event ID, the linked account and the instruction confirmation. They explain which date established the match and show the request amount on the same case. If the source statement later corrects the event, preserve the original movement and record the correction in the evidence trail. The Auditor should be able to follow the decision without guessing from an account total.

• Unmatched movements — See provider events by account, amount and state before choosing one to investigate.
• Confirmed instructions — Open the instruction and its evidence when testing a movement against the confirmed date.

Follow instruction review, provider confirmation and account reconciliation to see how this work joins the next stage.
