The EUTL shall periodically initiate data reconciliation to ensure that the EUTL's records of accounts, holdings of Kyoto units and allowances match the records of these holdings in the Union registry. For that purpose the EUTL shall record all processes.

The ITL periodically initiates data reconciliation to ensure that the ITL's records of the holdings of Kyoto units match the records of these holdings in the Union registry and every other KP registry.

If during the data reconciliation process referred to in paragraph 1, an irregularity, hereinafter referred to as ‘inconsistency’, is identified by EUTL, whereby the information regarding accounts, holdings of Kyoto units and allowances provided by the Union registry as part of the periodic reconciliation process differs from the information contained in the EUTL, the EUTL shall ensure that no further processes may be completed with any of the accounts, allowances or Kyoto units which are the subject of the inconsistency. The EUTL shall immediately inform the Central Administrator and the administrators of the relevant accounts of any inconsistency.
