FINRA Series 7Processes and Confirms TransactionsMedium

A broker-dealer's operations department receives a trade confirmation from a contra-broker showing a quantity that does not match the firm's own trade blotter. What should the firm send to the contra-broker to formally dispute the trade details?

  1. AA Regulation SHO locate confirmation
  2. BA written complaint filed under FINRA Rule 4530
  3. CA Don't Know (DK) notice
  4. DAn amended Form U4
Show answer & explanation

Correct answer: C. A Don't Know (DK) notice

A DK (Don't Know) notice is sent between broker-dealers when one party does not recognize or agree with the details of a trade reflected on a confirmation received from the contra-party, prompting reconciliation before settlement.

Why the other options are wrong

  • A. Reg SHO locates pertain to short sale borrowing confirmation, not trade matching disputes.
  • B. FINRA Rule 4530 involves customer complaint reporting, not inter-dealer trade discrepancies.
  • D. Form U4 relates to registered representative registration, not trade discrepancies.

DK (Don't Know) Notice

A notice sent by a broker-dealer to a contra-party when it does not recognize or cannot verify the details of a trade shown on a received confirmation.

  • Used for inter-dealer trade discrepancies
  • Prompts reconciliation before settlement
  • Distinct from customer complaint procedures

Memory trick: DK = 'I Don't Know this trade' — send it back to fix the mismatch.
