6.3 Institutional Allocation, Affirmation and DVP

Institutional Settlement Mechanics: DVP/RVP & SEC Rule 15c6-2

While retail trades execute and settle directly through the client's single brokerage account, institutional trading involves a tri-party operational model comprising three independent entities:

1. The Institutional Investment Manager (RIA/Fund Manager): Formulates the investment strategy, enters parent orders, and directs portfolio allocations;
2. The Executing Broker-Dealer: Executes trade orders in the public marketplace or alternative trading systems (ATS);
3. The Custodian Bank or Trust Company: Holds legal custody of the institutional client's cash and securities independently of the executing broker.

Delivery Versus Payment (DVP) and Receive Versus Payment (RVP)

Institutional accounts trade on a DVP/RVP basis (historically designated as Cash on Delivery or COD accounts):

• Delivery Versus Payment (DVP): Applies when the institutional client buys securities. The executing broker-dealer delivers the purchased securities to the client's custodian bank against simultaneous payment of cleared cash funds by the custodian bank.
• Receive Versus Payment (RVP): Applies when the institutional client sells securities. The executing broker-dealer receives the sold securities from the client's custodian bank against simultaneous payment of sales proceeds to the custodian bank.
• Linked Settlement: DVP/RVP links securities delivery and payment to reduce principal risk; operational, funding and default risks still need controls.

Institutional Trade Confirmation, Allocation & Electronic Affirmation

Institutional block trades execute through a precise sequence of back-office communications:

1. Block Execution: The investment manager executes an aggregate parent order (e.g., 500,000 shares across multiple underlying funds).
2. Trade Allocation: Following execution, the investment manager transmits an electronic allocation breakdown, apportioning specific share blocks and settlement instructions across individual sub-accounts.
3. Electronic Trade Confirmation (ETC): The executing broker-dealer transmits an electronic confirmation detailing trade terms (CUSIP, quantity, average price, commission/fees) to the manager and custodian bank via DTCC Institutional Trade Processing (ITP) platforms.
4. Electronic Affirmation: The custodian bank (or investment manager acting on its behalf) reviews the trade terms against its internal records and formally affirms the transaction.

Same-day Affirmation and the Industry 9:00 p.m. Cutoff

To eliminate settlement bottlenecks under the compressed T+1 settlement cycle, the SEC adopted SEC Rule 15c6-2:

• Rule Mandate: Broker-dealers engaging in institutional transactions subject to Rule 15c6-1 must either:
  1. Enter into written agreements with relevant institutional counterparties governing trade allocation, confirmation, and affirmation; or
  2. Establish, maintain, and enforce written policies and procedures reasonably designed to ensure completion of allocations, confirmations, and affirmations as soon as technologically practicable and no later than the end of the day on trade date (T+0).
• Industry Processing Cutoff: DTCC’s 9:00 p.m. Eastern trade-date affirmation cutoff supports automated DTC institutional processing. It is an industry processing cutoff, distinct from the rule’s end-of-trade-date standard, and is not a universal CNS netting mandate.
• Missed Cutoff: A late affirmation may require another processing route and closer monitoring. It does not by itself mean the trade has failed or that a securities-law deadline is exactly 9:00 p.m. Reconcile the actual DTC instructions, settlement status and funding needs.

Mismatched Allocation Example

A manager executes 10,000 shares but sends allocations totaling 9,500. Affirming the block without resolving the missing 500 leaves an allocation break. Ask the manager to confirm the complete breakdown, validate account/SSI data, and preserve changes. Do not put the difference in an unrelated client’s account to reach the cutoff.

Confirmation verifies proposed terms; affirmation communicates agreement; settlement exchanges assets and money. A successful affirmation is not proof that payment occurred. Reconcile the depository’s final status and resolve failed legs.

Rule 15c6-2 does not offer a safe harbor for affirming 90% of trades. Its applicable steps concern each transaction within scope, even if a firm meets an industry performance target.
