4.3 Trade Corrections and Error Accounts

Trade Corrections, Adjustments & As/Of Trade Processing

In broker-dealer back-office operations, trade reconciliation routines continuously identify discrepancies between internal execution tickets, counterparty clearing confirmations, and customer account allocations. Correcting these discrepancies requires standardized accounting adjustments and trade reporting modifications.

"As/Of" Trade Processing

An "as/of" trade is a transaction executed on a prior business date that was not reported or submitted to clearing on the actual trade date.

• Operational Scenarios: Common causes include temporary communications outages, manual floor execution tickets held for allocation verification, delayed block trade breakdowns from institutional investment advisers, or off-hours trading sessions.
• Reporting Mechanics: When submitting an "as/of" execution to the TRF, ORF, or TRACE, operations specialists must append the regulatory "as/of" trade modifier. The electronic report must include both the actual historical trade date and time of execution as well as the current reporting timestamp.
• Clearing Impact: "As/of" trades do not settle regular-way from the reporting date; instead, they are routed to the clearing corporation (NSCC/DTCC) with instructions to accelerate settlement or post immediate book-entry cash and position movements to reconcile the historical trade date.

Post-Settlement Date Adjustments

When operational breaks or incorrect trade bookings remain undetected until after regular-way settlement (T+1), determine the applicable clearing correction process; some adjustments require manual or special handling:

• Operations specialists must execute post-settlement journal entries across firm settlement accounts and customer sub-ledgers.
• The firm must adjust its master stock record to reflect the proper ownership entitlements and box/depository locations.
• Under SEC Rule 10b-10, the broker-dealer must cancel the original trade confirmation and transmit an amended confirmation clearly marked "Corrected Confirmation" to the customer, displaying the revised settlement dates, pricing, or share quantities.

Cancellations and Rebills: FINRA Rule 4515 Mandates

A cancellation and rebill (cancel/rebill) is an internal operational procedure wherein an executed trade is canceled out of one customer account and re-entered (rebilled) into another customer account.

Common Operational Triggers

• Account Number Transposition: A registered representative or order entry clerk transposes numbers when typing the customer account identifier (e.g., entering account 123-45678 instead of 123-45687).
• Bunched Order Allocations: An institutional investment manager executes a block order across multiple managed client sub-accounts and provides an erroneous post-trade allocation breakdown to the carrying broker-dealer.
• Name Confusion: An order is erroneously entered under a client's individual account rather than their joint account, trust, or corporate entity.

Strict Supervisory Requirements under FINRA Rule 4515

Under FINRA Rule 4515 (Approval and Documentation of Changes in Account Name or Designation), member firms are subject to strict regulatory controls before changing the account designation on any order:

1. Written Principal Approval: No change in account name, number, or designation can be made on an order ticket or customer ledger without the prior or contemporaneous written approval of a registered principal (such as a General Securities Principal - Series 24).
2. Investigation of Cause: The registered principal must personally investigate the circumstances surrounding the requested change and determine that the correction is bona fide, justified, and legitimate.
3. Documented Written Explanation: The firm must create and preserve a comprehensive written record detailing the exact reason for the change in account designation, signed or authenticated by the approving principal.
4. Three-Year Record Retention: Pursuant to SEC Rule 17a-4, all documentation supporting cancellation and rebill approvals must be retained for at least three years, the first two years in an easily accessible place.
5. Absolute Prohibition of Unilateral Rep Changes: Registered representatives and operational staff are strictly prohibited from changing account designations on their own authority. This prevents representatives from concealing trading losses, hiding unauthorized trades, parking positions, or engaging in tax fraud by transferring losing trades between client accounts.

Broker-Dealer Error Accounts: Operational Framework & Close-Out

Despite automated systems, human and algorithmic trading errors occur. Every carrying and clearing broker-dealer maintains a dedicated proprietary account known as an Error Account to isolate, manage, and resolve execution blunders.

Common Broker-Dealer Trading Errors

• Wrong Security Symbol: Buying 1,000 shares of MRK (Merck) when the customer explicitly instructed buying MSFT (Microsoft).
• Incorrect Order Quantity: Executing 5,000 shares when the customer entered an order for 500 shares.
• Execution on Wrong Side of Market: Selling 200 shares when the customer ordered a purchase of 200 shares.
• Order Type Mismanagement: Executing a customer's limit order as a market order at a price inferior to the customer's specified limit.
• Duplicate Execution: System latency causes an order desk to submit an order twice, filling double the customer's intended position.

Step-by-Step Error Resolution Protocols

1. Customer Remediation: Preserve the original instructions and escalate to the designated supervisor. Determine the customer’s proper treatment and any firm-funded price adjustment; do not fabricate a historical market execution. Record a current hedge or replacement execution separately from the approved customer adjustment.
2. Journaling to the Error Account: The erroneous or excess securities are removed from the customer's account and transferred directly into the broker-dealer's proprietary error account.
3. Prompt Risk Resolution: Follow approved procedures to close or hedge error exposure and document responsibility. There is no universal rule requiring every error position to be liquidated instantly regardless of market conditions. Do not use an error account as an unauthorized speculative account.
4. Firm Expense Absorption: All financial losses resulting from error liquidations must be absorbed completely by the broker-dealer as a business operating expense.
5. Regulatory Prohibitions Regarding Error Profits and Losses:
   • No Customer Loss Allocation: A broker-dealer cannot charge or pass through any loss from an error account to a customer.
   • No Rep Account Allocation: A firm cannot allocate error account losses or profits to a registered representative's personal account, nor can a firm offset representative payroll compensation against trading losses without formal contractual agreements compliant with labor and supervisory rules.
   • Error Profits: Allocate profits and losses under the approved error-resolution policy and customer obligations. Do not cherry-pick profitable errors for an employee or selectively place losses on customers.
