How Can a Firm Prove Best Execution for an Asset with No Publicly Quoted Price?

Concept

The obligation to secure best execution for an asset with no publicly quoted price presents a fundamental challenge to conventional compliance frameworks. For liquid, exchange-traded instruments, the process is anchored in a visible, continuous stream of data ▴ a public ledger of price and volume against which execution quality can be quantitatively measured. When this public price signal is absent, as with bespoke over-the-counter derivatives, privately held securities, or unique real-world assets, the very definition of “best” becomes a construct of process rather than a point of comparison. Proving it requires a shift in thinking, moving from a reactive validation against a market feed to a proactive construction of a defensible, documented, and repeatable valuation methodology.

At its heart, this is a problem of information asymmetry and procedural integrity. The firm stands in place of the public market, and its internal processes must therefore replicate the market’s functions of price discovery and fair dealing. This is not a theoretical exercise. Regulators, investors, and auditors require a concrete audit trail demonstrating that the final execution price was the most favorable possible under the prevailing circumstances.

The absence of a ticker symbol does not absolve a firm of this duty; it elevates the importance of the firm’s own internal systems for establishing a fair value benchmark. The core task is to create a price, or a narrow range of justifiable prices, where none existed before, and to do so in a way that is transparent, methodologically sound, and insulated from conflicts of interest.

This endeavor rests upon a foundational principle ▴ that value can be derived and defended even without a continuous public quotation. It necessitates a framework where qualitative judgment is supported by quantitative inputs and where every step of the price discovery journey is meticulously logged. The firm must, in effect, build a private market for the asset at the moment of execution, complete with its own set of rules, participants, and a mechanism for arriving at a price that can withstand subsequent scrutiny. The quality of this internal market-making process becomes the proxy for execution quality itself.

Strategy

A firm’s strategy for demonstrating best execution for illiquid assets must be built on a twin foundation of robust valuation methodologies and a rigorous price discovery protocol. This strategic framework is not a single action but a comprehensive system designed to produce a defensible execution price. The primary goal is to construct a “fair value” benchmark that serves as the yardstick against which the final transaction is measured. This requires a multi-pronged approach that synthesizes internal analysis with external data points, however sparse they may be.

The strategic imperative is to create a documented, evidence-based narrative that justifies the transaction price through a consistent and logical process.

Constructing the Valuation Framework

The initial step is to establish a formal valuation policy specifically for non-publicly priced assets. This policy should stipulate the acceptable methodologies for determining fair value. The choice of methodology is context-dependent, dictated by the nature of the asset and the availability of relevant data. A well-defined hierarchy of valuation techniques ensures consistency and objectivity in the process.

• Comparable Transaction Analysis ▴ This method involves identifying and analyzing recent transactions in similar, though not identical, assets. For a private equity stake, this could mean looking at recent acquisitions of companies in the same industry with similar growth profiles and financial metrics. The key is to make defensible adjustments for differences in size, profitability, market position, and the specific terms of the deal.
• Internal Valuation Models ▴ For assets that generate cash flows, such as a private credit instrument or a real estate holding, discounted cash flow (DCF) models are a cornerstone of valuation. The integrity of a DCF analysis hinges on the quality and justification of its inputs ▴ projected cash flows, the discount rate, and the terminal value. Each input must be documented and its derivation explained.
• Reference Pricing from Proxies ▴ In some cases, a publicly traded instrument can serve as a loose proxy. For instance, the valuation of a private company might be benchmarked against the enterprise value-to-EBITDA multiple of a publicly traded competitor. Adjustments for illiquidity, control premiums, and differences in scale are critical for this method to be credible.

The Price Discovery Mandate

Valuation provides a theoretical price range; price discovery is the practical process of testing that range in the real world. For illiquid assets, this almost always involves a structured, competitive process designed to elicit the best possible terms from a pool of potential counterparties. The strategy here is to create competitive tension where none naturally exists.

A systematic Request for Quote (RFQ) process is a central pillar of this strategy. A firm must solicit bids or offers from multiple independent counterparties. The selection of these counterparties should be deliberate and documented, focusing on entities with a known appetite and capacity for the specific type of asset. Soliciting quotes from a minimum number of dealers (e.g. three to five) is a common best practice that provides a tangible record of the market’s depth and interest at a specific point in time.

Each quote, and the time it was received, must be logged. This process transforms an abstract valuation into a concrete, executable price.

Comparative Strategic Approaches

The following table outlines different strategic frameworks for proving best execution, highlighting their applicability and primary documentation requirements.

Execution

The execution phase is where the strategic framework for best execution is operationalized. It involves the systematic implementation of valuation and price discovery protocols, culminating in a transaction that is supported by a comprehensive and irrefutable audit trail. This is a procedural discipline, requiring meticulous record-keeping and a clear separation of duties within the firm.

An unimpeachable audit trail is the ultimate proof of best execution in the absence of a public market price.

The Operational Playbook for Illiquid Transactions

Executing a transaction in an illiquid asset requires a formal, step-by-step process. This operational playbook ensures that all necessary actions are taken and documented, from the initial valuation to the final settlement. A standing committee, often called the Valuation Committee, should oversee this process, providing independent review and approval at critical junctures.

1. Pre-Trade Valuation and Benchmarking ▴
   • Step 1 ▴ The trading desk or portfolio manager initiates a request for valuation.
   • Step 2 ▴ An independent internal valuation team (or a qualified third-party appraiser) is engaged to prepare a formal valuation report. This report must detail the methodology used, all key assumptions, and the data sources consulted.
   • Step 3 ▴ The Valuation Committee reviews and approves the pre-trade valuation report, establishing a “fair value” range and a target execution price. This becomes the internal benchmark for the transaction.
2. Documented Price Discovery ▴
   • Step 1 ▴ The trading desk identifies a list of potential counterparties based on the firm’s approved counterparty list and their known activity in the asset class. The rationale for selecting these specific counterparties is documented.
   • Step 2 ▴ A formal RFQ is sent to the selected counterparties, specifying the asset and desired transaction details. All communications must be recorded.
   • Step 3 ▴ As quotes are received, they are logged in a centralized system with timestamps. The log should include the counterparty name, the bid or offer price, the quantity, and any specific conditions attached to the quote.
3. Execution and Post-Trade Analysis ▴
   • Step 1 ▴ The trader executes the transaction with the counterparty providing the most favorable price relative to the internal benchmark and other quotes received. If the best quote is not chosen, a detailed justification must be documented (e.g. due to counterparty credit risk or settlement concerns).
   • Step 2 ▴ A post-trade execution report is compiled. This report compares the final execution price to the pre-trade benchmark and all other quotes received. It should calculate and explain any variance.
   • Step 3 ▴ The Valuation Committee reviews the post-trade report to certify that the process was followed correctly and that best execution was achieved. This final certification is attached to the transaction record.

Quantitative Documentation and the Audit Trail

The strength of the best execution case rests on the quality of its documentation. The audit trail must be sufficiently detailed to allow an independent third party, such as an auditor or regulator, to reconstruct the entire transaction lifecycle and arrive at the same conclusion. This requires more than just a summary; it demands granular, quantitative data.

The following table provides an example of a price discovery log for the sale of an illiquid corporate bond. This log is a critical component of the audit trail.

In this example, the firm’s pre-trade benchmark might have been 98.55. By executing at 98.65 with Dealer B, the firm can demonstrate that it achieved a price superior to its own internal valuation and to the other quotes received. The log provides clear, time-stamped evidence of the competitive process, forming the backbone of the best execution defense.

FINRA Rule 5310, for instance, requires firms to use “reasonable diligence” to ascertain the best market, and a documented, competitive process like this is a primary means of demonstrating that diligence. The process itself becomes the evidence.

Reflection

Calibrating the Internal Compass

The framework for proving best execution in the absence of public prices is ultimately a reflection of a firm’s internal culture and operational discipline. It moves the locus of responsibility from the external validation of a market feed to the internal integrity of a firm’s own processes. The systems and procedures a firm builds to value and transact these assets are not merely compliance tools; they are a direct expression of its commitment to its fiduciary duty. The quality of the audit trail is a proxy for the quality of the firm’s judgment.

Considering this, the essential question for any principal or portfolio manager is not “Can we defend this trade?” but rather “Is our valuation and price discovery system fundamentally sound?” A robust system yields defensible trades as a natural output. It fosters a discipline of inquiry, demanding that assumptions be tested, that competition be sought, and that every step be documented. This process transforms the abstract concept of fiduciary duty into a set of concrete, repeatable, and auditable actions. The ultimate advantage lies in building an operational framework so rigorous that it makes the question of best execution self-evident.
