6.4 DKs, Aged Fails, Buy-ins and Reclamations

In a compressed T+1 settlement environment, back-office operations must operate with heightened vigilance to resolve trade exceptions and settlement failures. When trade terms mismatch, counterparties fail to recognize transactions, or physical and electronic deliveries break down, broker-dealers must follow strict regulatory escalation protocols established by FINRA's Uniform Practice Code (Rule 11000 Series) and SEC financial responsibility rules. Failure to resolve exceptions within statutory timeframes leads to punitive net capital deductions, mandatory open-market close-outs, and significant financial liability.

Trade Comparison Exceptions & Discrepancies

Trade clearance begins with trade comparison—the process of validating that both the buying broker-dealer and the selling broker-dealer agree upon all contractual terms of an executed transaction. Comparison occurs through centralized clearing facilities such as NSCC's trade capture engine or FINRA/exchange trade reporting facilities (TRFs).

Compared vs. Uncompared Trades

• Compared (Locked-In) Trades: When both trading parties submit matching transaction data—including CUSIP symbol, share quantity, execution price, settlement date, and broker capacity—the trade is considered a compared trade. Once compared, it is locked in and flows automatically into NSCC's Continuous Net Settlement (CNS) system.
• Uncompared Trades: If an executed trade cannot be matched against a corresponding submission from the contra-party, it remains uncompared. Uncompared trades arise from:
  1. Quantity Discrepancies: One broker reports 5,000 shares while the other reports 500 shares;
  2. Price Mismatches: Discrepancies in execution price or net contract amount;
  3. Symbol or CUSIP Errors: Conflicting security identifiers;
  4. Omission of Trade Submission: One broker fails to report the execution entirely; or
  5. Capacity or Settlement Disagreements: Conflicting settlement dates or commission/capacity designations.

Operations personnel must investigate and reconcile uncompared trades immediately on trade date (T+0). Under T+1 settlement rules, uncompared trades that remain unresolved by market open on settlement date drop out of automated clearing, forcing the firms into manual, high-risk trade reconciliation.

DK Notices and Confirmation of Aged Fails

A don’t know (DK) notice advises a counterparty that the reported transaction is not recognized or does not match the firm’s records. Promptly compare the order ticket, execution report, counterparty, CUSIP, price, quantity, trade date and settlement terms. A DK does not erase a valid contract or authorize ignoring incoming communications.

Rule 11210 provides comparison/confirmation and voluntary DK procedures, including current trade-date confirmation requirements for covered transactions. Automated systems have their own accept/decline workflows. There is no universal rule that every electronic trade must be DK’d within 20 minutes or that every DK has a four-business-day investigation holiday.

Retain the notice and response, assign a responsible investigator and follow the applicable rule/facility deadline. A mistaken duplicate report calls for a traceable cancellation; an actual missing execution needs booking and confirmation. Staff must not accept a false trade solely to clear an exception queue.

For aged fails, reconcile open contracts with the contra-firm and available clearing-agency repricing/reconfirmation services. Confirm security, amount, original dates, open quantity and price. Investigate items that one firm considers settled while the other still lists as failed. Reconfirmation verifies an outstanding obligation; it is not a new transaction that restarts aging.

If a received 2,000-share trade has no ticket, contact the desk and contra-party immediately. It may be a wrong account, wrong counterparty, duplicate or genuinely missing trade. Document the outcome and adjust every affected reporting and ledger system. Never reset the trade date to hide a late booking.

Fails, Balance-sheet Exposure and Capital Review

A fail to deliver means the selling side has not delivered securities by the due date. A fail to receive means expected securities have not arrived. Record the open security obligation and associated money amount consistently. An FTD monetary receivable and FTR monetary payable are common ledger representations, but the full transaction must be reconciled rather than inferred from an asset/liability label alone.

Aged fails can create market exposure, possession/control deficits, funding needs and net-capital deductions. Their treatment depends on the rule, age, collateral, market value and related positions. There is no universal rule of zero charge for four days, 15% on days 5–20 and 100% on day 21. Refer the actual facts to the FINOP and the applicable Rule 15c3-1 provisions.

A fail’s capital treatment does not replace a Regulation SHO Rule 204 closeout deadline or a customer-delivery requirement under Rule 15c3-3(m). The same position may require several controls. A monetary haircut is not permission to leave a mandatory closeout unperformed.

Maintain an aged-fail report identifying settlement date, business-day age, security, quantity, counterparty, reason, value, control deficit and action. Prioritize items affecting customer assets and upcoming corporate actions. A dividend due bill or stock split can change the quantity or money owed while the original fail remains open.

For a customer entitlement supported by a failed receipt, confirm whether the firm has sufficient eligible shares elsewhere. If not, possession/control remediation may be necessary even though the ledger balances. Preserve recall, borrow, buy-in and extension evidence rather than use a suspense entry as a substitute.

Buy-In Procedures under FINRA Rule 11810

When a selling broker-dealer fails to deliver securities on settlement date, the buying broker-dealer is not obligated to wait indefinitely. Under FINRA Rule 11810 (Buy-in Procedures), the buying broker holds the statutory right to close out the contract by purchasing the securities on the open market at prevailing prices.

Step-by-Step Buy-In Lifecycle

1. Issuance of Buy-In Notice:
   • The buying broker cannot simply execute a buy-in without advance warning.
   • The buyer must deliver a formal written Notice of Buy-In to the failing seller.
   • Notice Timing: The notice must be delivered no later than 12:00 noon Eastern Time, at least two business days prior to the proposed execution date.
2. Re-transmittal of Notice (Liability Notice):
   • If the failing seller is itself failing to receive those identical securities from another broker-dealer (a multi-party chain of fails), the seller can re-transmit the notice to its defaulting contra-party.
   • Follow the rule’s retransmission deadlines and receipt requirements for the actual notice; a universal 1:00 p.m. same-day cutoff is not correct.
3. Execution of Buy-In:
   • Under Rule 11810, the earliest ordinary buy-in is the third business day after delivery was due, with notice delivered by noon ET two business days before the proposed execution. These are different clocks. Clearing-agency/exchange rules and the rule’s exclusions can change the applicable process.
   • Cancellation upon Delivery: If the failing seller tenders good delivery of the securities before the buy-in is executed, the buy-in is immediately canceled.
4. Financial Settlement and Liability:
   • If the open-market purchase price is higher than the original trade price, the failing seller is strictly liable for the entire price differential plus all execution costs and brokerage fees.
   • Reconcile the actual closeout price, contractual difference and expenses under the governing process; do not invent a general “no gain” accounting rule.

Sell-Out Procedures under FINRA Rule 11820

A sell-out is the converse of a buy-in. It occurs when a selling broker-dealer tenders good delivery of securities to the buying broker on or after settlement date, but the buying broker fails or refuses to accept good delivery and pay for the securities.

Operational Characteristics of a Sell-Out

• Immediate Execution: Unlike buy-ins, which mandate a multi-day advance notice requirement, FINRA Rule 11820 authorizes the selling broker to execute a sell-out immediately without an advance waiting period upon the buyer's refusal to accept good delivery.
• Market Execution: The selling broker sells the securities in the open market on the day of refusal or the following business day.
• Defaulting Buyer Liability: The defaulting buyer is strictly liable for any loss resulting from the difference between the original contract price and the lower sale price realized in the open market, plus all associated transaction expenses.

Rejection and Reclamation

Rejection refuses a defective delivery at presentation. Reclamation returns securities or asserts a claim after an accepted delivery because a defect is later discovered. Check the applicable instrument, defect and rule before choosing a deadline.

Rule 11720 provides a 30-month period measured from the contract’s settlement date for irregular delivery, transfer-agent refusal, and lost/stolen/confiscated securities within its scope. It does not impose a general 30-day legal-document limit or one-day limit for all minor irregularities. Other specific rules and non-UPC remedies may apply.

Document the original delivery, defect, certificate details, transfer-agent communication and reclamation notice. Do not return a different certificate or omit quantity and value reconciliation. A transfer-agent refusal after acceptance is a classic reclamation problem; a missing endorsement spotted immediately is a delivery-rejection problem.

A good-delivery dispute does not justify a DK of a trade the firm knows it executed. Separate whether the contract exists from whether delivery satisfies it. Escalate uncertain defects promptly, preserve the claim and avoid allowing a generic deadline table to replace the applicable rule.
