6.2.1.2.1. Comparison and Verification of Confirmations
Once a confirmation has been received, each party must compare and verify the confirmation. Sometimes a party will receive a confirmation for a transaction with terms and conditions it does not accept. It may even receive a confirmation for a transaction it does not recognize at all. The party who finds a discrepancy must promptly report it to the other party, and the erring party must send a corrected trade confirmation within one business day following a resolution. If the parties cannot resolve their differences, both should send a written notice of non-recognition (also called a “don’t know” or DK notice).
If a party doesn’t recognize a trade, it must promptly try to determine whether a trade occurred, and if the unrecognized trade confirmation was correct, it must immediately notify the confirming party by phone and send a written trade confirmation within one business day.

The party receiving the DK notice should then check its records, and if it agrees with the other party, it should cancel the trade.
If a party sends a trade confirmation but fails to receive either a trade confirmation or a DK notice from the other party, the first party should determine whether a trade occurred. This determination should occur no earlier than T + 4 and no later than T + 8. If it believes that a trade occured it must immediately notify the other party by phone and send a failure to confirm within one business day. The other party should then try to determine whether a trade occurred, and if they find the transaction did occur, they should immediately phone the other party and send a confirmation within one business day. If they can’t find evidence that it occurred, they should promptly send the other party a DK notice.
If the discrepancies cannot be resolved by c
