Where all the conditions of paragraph 1 are met, a trade repository shall undertake the following steps, using the latest reported value for each of the fields in Table 2 of the Annex as of the preceding working day: **(a)** a trade repository having received a derivative report shall verify whether it has received a corresponding report from or on behalf of the other counterparty; **(b)** a trade repository that has not received a corresponding derivative report as referred to in point (a) shall attempt to identify the trade repository that has received the corresponding derivative report by communicating to all registered trade repositories the values of the following fields of the reported derivative: ‘Unique Transaction Identifier’, ‘Counterparty 1’ and ‘Counterparty 2’; **(c)** a trade repository that determines that another trade repository has received a corresponding derivative report referred to in point (a) shall exchange with that trade repository the details of the reported derivative in an XML format and a template developed in accordance with the ISO 20022 methodology; **(d)** a trade repository shall treat a reported derivative as reconciled where the details of that derivative subject to reconciliation match the details of the corresponding derivative as referred to in point (a) and in accordance with the applicable tolerance limits and relevant dates of application as laid down in Table 2 of the Annex; **(e)** a trade repository shall subsequently assign values for the reconciliation categories for each reported derivatives transaction, as set out in Table 3 of the Annex; **(f)** a trade repository shall conclude the steps in points (a) to (e) at the earliest opportunity and shall take no such steps after midnight Universal Coordinated Time on a given working day; **(g)** a trade repository that cannot reconcile a reported derivative shall seek to match the details of that reported derivative on the following working day. The trade repository shall no longer seek to reconcile the reported derivative thirty calendar days after the derivative is not outstanding. 4. A trade repository shall confirm the total number of paired derivatives and the number of reconciled derivatives with each trade repository with which it has reconciled derivatives at the end of each working day. A trade repository shall have in place written procedures for ensuring the resolution of all discrepancies identified in this process. 5. No later than sixty minutes after the conclusion of the reconciliation process as set out in point (f) of paragraph 3, a trade repository shall provide the report submitting entities with the results of the reconciliation process performed by it on the reported derivatives. A trade repository shall provide those results in an XML format and a template developed in accordance with the ISO 20022 methodology, including information on the fields that have not been reconciled.
