## Concept

A global firm’s [Best Execution Committee](https://prime.greeks.live/area/best-execution-committee/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) does not merely exist to satisfy a line-item on a compliance checklist. Its function is far more integral. It operates as the central cognitive unit for the firm’s entire trading architecture, a system designed to navigate the complex, often divergent, regulatory currents of global markets. Your question regarding the structuring of its [review process](https://prime.greeks.live/question/how-does-the-best-execution-review-process-differ-for-fully-automated-versus-high-touch-orders/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) to address both EU and US nuances is a question of system design.

It presupposes that a single, monolithic process is insufficient. You are correct. The task is to engineer a [governance framework](https://prime.greeks.live/area/governance-framework/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that is both globally coherent and locally responsive, capable of processing and acting upon data from two distinct regulatory philosophies without generating internal friction.

The core challenge originates in the philosophical differences between the European Union’s Markets in Financial Instruments Directive (MiFID II) and the United States’ framework, primarily governed by the [Financial Industry Regulatory Authority](https://prime.greeks.live/area/financial-industry-regulatory-authority/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (FINRA). MiFID II is principles-based and prescriptive, demanding that firms take “all sufficient steps” to achieve the best outcome and requiring extensive data collection and reporting (like RTS 27 and RTS 28 reports) to prove it. The US system, while also principled, is rooted in a “[facts and circumstances](https://prime.greeks.live/area/facts-and-circumstances/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite)” analysis, focusing on “reasonable diligence.” A committee’s review process must therefore be architected to satisfy the EU’s demand for exhaustive evidence while simultaneously respecting the US focus on holistic, case-by-case justification.

> A properly structured committee transforms regulatory compliance from a reactive burden into a source of competitive intelligence and operational efficiency.

This requires moving beyond a simple comparison of rules. It demands the creation of a unified data ontology ▴ a common language for [execution quality](https://prime.greeks.live/area/execution-quality/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) that can be understood across the enterprise. The committee’s review process is the mechanism that translates raw [execution data](https://prime.greeks.live/area/execution-data/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), through this common language, into actionable intelligence.

It identifies inefficiencies in routing, weaknesses in algorithmic strategies, and suboptimal venue choices, feeding these insights back into the trading system for iterative improvement. The structure of this review process, therefore, directly dictates the learning capacity and evolutionary potential of the firm’s entire execution apparatus.

## Strategy

Designing a bicoastal review process for a [Best Execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Committee requires a deliberate strategy that harmonizes data, governance, and reporting. The objective is to create a single, efficient system that produces tailored outputs for different regulatory regimes. This is achieved by building a modular framework with a globally consistent core and jurisdiction-specific analytical modules.

![Precision-engineered multi-layered architecture depicts institutional digital asset derivatives platforms, showcasing modularity for optimal liquidity aggregation and atomic settlement.

## A Unified Governance and Data Framework

The foundation of the strategy is a unified governance charter that defines the committee’s mandate, authority, and composition. This charter must explicitly acknowledge the dual regulatory obligations. The next layer is the [data framework](https://prime.greeks.live/area/data-framework/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The committee must ingest a wide array of execution data, normalized into a consistent format.

This is the single most important strategic decision. Without a common data baseline, any attempt at a unified review is destined for failure.

The system must capture at minimum:

- **Order Characteristics** ▴ Timestamp (nanosecond precision), asset class, instrument, size, order type, and any specific client instructions.

- **Execution Data** ▴ Venue of execution, execution price, execution time, commissions, fees, and any third-party costs.

- **Market Data** ▴ Top-of-book and depth-of-book data from relevant exchanges and liquidity sources at the time of order handling and execution. This must be time-synchronized with the order and execution data.

## What Are the Core Regulatory Differentiators?

The strategic review process must be built around the primary differences between the EU and US regimes. While both aim for client protection, their methodologies diverge significantly. The committee’s analytical process must be designed to address these specific points of divergence.

The EU’s [MiFID II](https://prime.greeks.live/area/mifid-ii/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is notably more prescriptive regarding the factors that must be considered and the evidence required to demonstrate compliance. In contrast, the US framework provides firms with more flexibility in determining the relative importance of execution factors based on the specific context of an order.

The following table outlines the key strategic distinctions that the committee’s review process must be architected to handle.

### Table 1 ▴ Comparative Analysis of EU vs. US Best Execution Principles

| Factor | EU (MiFID II) Framework | US (FINRA Rule 5310) Framework |
| --- | --- | --- |
| Governing Principle | Firms must take “all sufficient steps” to obtain the best possible result. This implies a high and continuous standard of effort. | Firms must use “reasonable diligence” to ascertain the best market for the security and buy or sell so that the resultant price is as favorable as possible under prevailing market conditions. |
| Execution Factors | Explicitly lists price, costs, speed, likelihood of execution and settlement, size, nature, and any other relevant consideration. For retail clients, total consideration (price plus costs) is paramount. | Lists factors including the character of the market, size and type of transaction, number of markets checked, accessibility of the quotation, and the terms and conditions of the order. |
| Venue Analysis | Requires firms to publish annual reports on the top five execution venues used for each class of financial instrument (RTS 28) and for venues to publish execution quality data (RTS 27). | Requires “regular and rigorous” review of execution quality. Less prescriptive on public reporting formats but covered under SEC Rules 605 and 606. |
| Policy & Disclosure | Order execution policy must be detailed, explaining the relative importance of factors and the selection process for venues. Must obtain prior client consent. | Firms must have procedures for ensuring best execution. Disclosure requirements focus on payment for order flow and order routing information. |

## The Modular Review Process

The strategy culminates in a modular review process. The committee conducts a single, unified review of execution quality based on its core data framework. The outputs of this review are then passed through two separate “lenses” or modules for reporting and attestation.

- **The EU Module** ▴ This module generates reports that directly map to MiFID II requirements. It emphasizes total consideration, produces the data needed for [RTS 28](https://prime.greeks.live/area/rts-28/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) summaries, and documents the “sufficient steps” taken for venue and algorithm selection.

- **The US Module** ▴ This module produces documentation demonstrating “reasonable diligence.” It might involve more qualitative write-ups for specific block trades or illiquid instruments, focusing on the “facts and circumstances” of the execution and the rationale for the strategy chosen.

This modular approach ensures efficiency. The core analytical work is done once. The outputs are then tailored to meet specific regulatory demands, allowing the committee to attest compliance in both jurisdictions without duplicating effort.

## Execution

The strategic framework is actualized through a disciplined, data-driven execution process. This operational playbook details the precise mechanics of the Best Execution Committee’s review cycle. The process is designed to be systematic, auditable, and capable of generating the specific evidence required by both EU and US regulators.

## The Quarterly Review Cycle a Procedural Guide

The committee’s work is centered around a recurring quarterly review cycle. This frequency is sufficient to identify trends and address issues in a timely manner without creating an excessive administrative load. The process is broken into distinct phases.

- **Data Aggregation and Preparation (Weeks 1-2)** ▴ The quantitative analysis team gathers and validates all relevant trading data for the preceding quarter. This includes all order, execution, and market data from the firm’s Order Management System (OMS), Execution Management System (EMS), and market data providers. The data is loaded into the firm’s [Transaction Cost Analysis](https://prime.greeks.live/area/transaction-cost-analysis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (TCA) engine.

- **Quantitative Analysis and Report Generation (Weeks 3-4)** ▴ The TCA engine processes the data, calculating a range of execution quality metrics against various benchmarks (e.g. Arrival Price, VWAP, TWAP). The system generates a standardized “[Best Execution Review](https://prime.greeks.live/area/best-execution-review/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Pack” which includes both quantitative dashboards and exception reports.

- **Qualitative Review and Business Unit Feedback (Week 5)** ▴ The review pack is distributed to the heads of the relevant trading desks. They are required to provide written commentary on any flagged exceptions, explain the rationale for specific execution strategies (especially for large or illiquid orders), and document any client instructions that influenced the outcome.

- **Committee Meeting and Deliberation (Week 6)** ▴ The committee convenes. The agenda is structured to move from a high-level overview to a detailed examination of exceptions and policy effectiveness. Decisions, action items, and escalations are formally recorded in the meeting minutes.

- **Action Item Follow-up and Attestation (Weeks 7-12)** ▴ The committee secretary tracks all action items to completion. The final minutes and review pack, along with any supplementary documentation, form the official record for that quarter. This record is used to complete regulatory attestations for both EU and US authorities.

## How Should the Committee Analyze Execution Data?

The core of the review meeting is the analysis of the Best Execution Review Pack. This pack must present a holistic view of execution performance. A key component is the TCA dashboard, which provides a summary of performance across asset classes and regions.

> The committee’s effectiveness is directly proportional to the quality and granularity of the data it reviews.

The following table is a simplified representation of a TCA dashboard that a committee would use. It is designed to provide a top-down view, allowing members to quickly identify areas requiring deeper investigation. The metrics are chosen to satisfy both the EU’s focus on cost and the US’s broader “facts and circumstances” approach.

### Table 2 ▴ Sample Quarterly TCA Dashboard Summary

| Asset Class | Region | Notional (USD MM) | Arrival Price Slippage (bps) | VWAP Slippage (bps) | Reversion (bps) | % Orders Flagged for Review |
| --- | --- | --- | --- | --- | --- | --- |
| Equities | US | 15,450 | -2.1 | +0.5 | -0.8 | 1.5% |
| Equities | EU/UK | 12,800 | -3.5 | -1.2 | -1.5 | 2.2% |
| Fixed Income | US | 25,200 | -1.8 | N/A | -0.5 | 0.8% |
| Fixed Income | EU/UK | 21,500 | -2.4 | N/A | -0.9 | 1.1% |
| FX | Global | 55,100 | -0.5 | N/A | -0.2 | 0.4% |

## Systematizing Venue and Broker Review

A critical function of the committee is the “regular and rigorous” review of execution venues and brokers. This cannot be an informal process. It must be systematized through a quantitative scoring framework.

The committee should maintain a scorecard for all key execution counterparties. This scorecard is updated quarterly as part of the review pack and provides an objective basis for decisions about where to route order flow.

This process directly supports the evidentiary requirements of MiFID II’s RTS 28 and the principles of FINRA 5310. It creates a clear, auditable trail demonstrating that the firm is actively monitoring the quality of its execution partners and making data-driven decisions to fulfill its duty to its clients.

### [How Do Regulators Define the “Most Favorable Terms” in Best Execution?](https://options.greeks.live/question/how-do-regulators-define-the-most-favorable-terms-in-best-execution/)
![A precision optical system with a reflective lens embodies the Prime RFQ intelligence layer.

### [How Do Regulators Define Best Execution for Algorithmic Strategies?](https://options.greeks.live/question/how-do-regulators-define-best-execution-for-algorithmic-strategies/)
![A dark blue, precision-engineered blade-like instrument, representing a digital asset derivative or multi-leg spread, rests on a light foundational block, symbolizing a private quotation or block trade.

Regulators define best execution for algorithmic strategies as a continuous, evidence-based duty of care, embedded in a robust technological and governance framework.

- 
### [How Does the Definition of ‘Cost’ Differ between FINRA and MiFID II for Best Execution Purposes?](https://options.greeks.live/question/how-does-the-definition-of-cost-differ-between-finra-and-mifid-ii-for-best-execution-purposes/)
![A sleek blue and white mechanism with a focused lens symbolizes Pre-Trade Analytics for Digital Asset Derivatives.

FINRA's 'cost' is an implicit result of seeking the best price; MiFID II's is an explicit, itemized 'total consideration' calculation.

- 
### [Can a Firm Be Penalized for Deficient Documentation Even with Favorable Execution Outcomes?](https://options.greeks.live/question/can-a-firm-be-penalized-for-deficient-documentation-even-with-favorable-execution-outcomes/)
![An exposed institutional digital asset derivatives engine reveals its market microstructure. The polished disc represents a liquidity pool for price discovery.

While both aim for client protection, their methodologies diverge significantly. The committee's analytical process must be designed to address these specific points of divergence. The EU's MiFID II is notably more prescriptive regarding the factors that must be considered and the evidence required to demonstrate compliance. In contrast, the US framework provides firms with more flexibility in determining the relative importance of execution factors based on the specific context of an order. "
