FINRA Rule 4340

Rule 4340 sits within the 4300 Operations section of the 4000 Financial and Operational Rules series. It was adopted by SR-FINRA-2013-035, effective May 1, 2014, simultaneously with FINRA Rules 4314 and 4330, as announced in Regulatory Notice 14-05. Rule 4340 replaced and consolidated prior NYSE Rule 405(a) — Know Your Customer — provisions related to callable securities, and NASD interpretive material addressing partial call allocations. It has not been amended since adoption.

Callable Securities: The Investor Protection Problem

A callable security is one whose terms permit the issuer — a corporation, municipality, or government agency — to retire the obligation before its scheduled maturity date. Issuers exercise call options most commonly when interest rates fall below the coupon rate on the outstanding securities, allowing them to refinance at lower cost. For investors, a call event carries important consequences: they lose an above-market income stream at precisely the moment when reinvestment opportunities are least attractive, they may receive the call price rather than a premium reflecting the security's market value, and they face reinvestment risk in a lower-rate environment.

When a call is partial rather than total — meaning the issuer redeems only a portion of the outstanding securities rather than the entire issue — broker-dealers holding positions for multiple customers in the same CUSIP face a specific operational problem. Not all of the securities held by the broker-dealer's customers will be called. Someone's position will be redeemed, often at a premium or at par; someone else's position will remain outstanding. The question of whose securities are selected for redemption is not determined by the issuer — it is determined by the broker-dealer through its internal allocation process. That allocation process creates a direct opportunity for favoritism: a firm could allocate favorable calls to favored customers or to the firm's own proprietary positions, and unfavorable calls — redemptions at below-market prices or in otherwise disadvantageous circumstances — to less favored customers or away from the firm's own account.

Rule 4340 addresses this conflict systematically. Its three core provisions — the fair and impartial allocation requirement, the favorable redemption prohibition, and the unfavorable redemption prohibition — together prevent a broker-dealer from using its position as allocator to advantage itself or its associated persons at the expense of its customers in either direction.

Allocation Procedures: Establishment, Website Publication, and Customer Notice

Rule 4340(a)(1) requires every member that has in its possession or under its control any callable security to establish procedures by which it will allocate among its customers, on a fair and impartial basis, the securities to be redeemed or selected as called in the event of a partial redemption or call. These procedures must be made available on the member's website.

The fair and impartial standard is not merely aspirational — it is an enforceable requirement with substantive content. Supplementary Material .02 confirms that acceptable allocation procedures include the use of an impartial lottery system, acting on a pro-rata basis allocating the call proportionally across all customer positions in the security, or such other means as will achieve a fair and impartial allocation. The common thread across all acceptable methodologies is that the selection of which customer positions are called must be random or mathematically objective — not based on the identity of the customer, the profitability of the account to the firm, the size of the customer's overall relationship, or any other factor that introduces favoritism. A firm that allocates calls based on relationship value, trading history, or any discretionary judgment not grounded in a pre-established objective methodology has violated the fair and impartial standard.

The website publication requirement is a transparency mechanism. By requiring the allocation procedures to be publicly accessible rather than maintained only in internal compliance documents, Rule 4340 creates accountability — any customer who receives a partial call allocation outcome they believe was unfair can access the firm's stated procedures and evaluate whether the allocation was consistent with them. FINRA examiners can likewise access and evaluate the procedures as published rather than having to reconstruct them from internal records.

Rule 4340(a)(2) requires members to provide written notice — which may be electronic — to new customers at the opening of an account, and to all customers at least once every calendar year, of the manner in which they may access the allocation procedures on the member's website. The notice must also inform customers that they may request hard copies of the allocation procedures, which the member must provide upon request. The annual notice cycle ensures that customers do not lose awareness of their rights over time, and the hard copy provision accommodates customers who lack convenient digital access.

Favorable Redemptions: Customers First

Rule 4340(b) imposes the most commercially significant of the rule's three provisions. Where redemption of callable securities is made on terms that are favorable to the called parties — meaning the called party receives a premium price, a below-market buyout, or any other outcome that is economically better than holding the position to maturity or selling in the market — the member must not allocate the securities to any account in which it or its associated persons have an interest until all other customers' positions in such securities have been satisfied.

The structure of this prohibition is categorical and unqualified. It is not a best-efforts obligation or a preference standard — it is a complete prohibition on favorable call allocation to firm or associated person accounts until every customer position in the security has been satisfied. A firm cannot include its proprietary account or any associated person's account in the pool of positions eligible for a favorable call until there are no remaining customer positions outstanding. Only after every customer has received their favorable call allocation does the firm's or associated person's position become eligible.

The rationale is straightforward and fundamental to securities regulation's conflict-of-interest philosophy. When an issuer makes a favorable call — paying above market, offering a premium, or redeeming in a manner that benefits the called party — that economic benefit should flow to customers before the firm and its personnel capture it. The firm's position as allocator creates an inherent conflict: without the Rule 4340(b) prohibition, a firm could simply ensure that its own proprietary position and the positions of its highest-earning employees always received favorable call treatment, effectively using the firm's custody role as a wealth transfer mechanism from customers to insiders.

Supplementary Material .01 introduces an important nuance regarding associated persons who perform solely clerical and ministerial functions. The rule's prohibition applies to accounts of associated persons as defined in Exchange Act Section 3(a)(18) — but that definition expressly excludes, for certain purposes, persons associated with the member whose functions are solely clerical or ministerial. For favorable redemptions, the rule expressly permits the member to include the accounts of clerical and ministerial associated persons in the pool eligible for favorable call allocation alongside customer accounts. The practical rationale is that clerical and ministerial staff who happen to hold the same securities as customers should not be categorically disadvantaged relative to customers when there is no meaningful conflict of interest driving their inclusion in the standard pool.

Unfavorable Redemptions: No Escape for the Firm

Rule 4340(c) addresses the mirror-image scenario — where redemption of callable securities is made on terms that are unfavorable to the called parties. In this context, a member must not exclude its positions or those of its associated persons from the pool of securities eligible to be called. The firm and its associated persons must participate in the unfavorable call lottery on equal terms with customers.

The unfavorable call provision addresses a subtler conflict of interest than the favorable call provision. In a favorable call context the temptation is to claim the benefit; in an unfavorable call context the temptation is to avoid the harm. Without Rule 4340(c), a firm could simply exclude its own proprietary positions and those of its registered personnel from the pool when an issuer exercises a call at below-market terms, ensuring that only customers' positions were subject to the unwanted redemption. Rule 4340(c) closes this escape route completely — the firm and its associated persons must bear their proportionate share of unfavorable call risk alongside customers.

Supplementary Material .01's treatment of clerical and ministerial associated persons again introduces nuance. For unfavorable redemptions, the rule's exclusion prohibition applies to the accounts of clerical and ministerial associated persons in the same way it applies to other associated persons — a firm shall not exclude those accounts from the pool either. The symmetry is complete: in favorable calls, clerical and ministerial accounts may be included with customers; in unfavorable calls, they may not be excluded from the pool. The direction of the constraint is always consistent with investor protection — customers are never disadvantaged relative to firm insiders in either direction.

Introducing and Clearing Member Arrangements

Supplementary Material .03 addresses the allocation question in the common commercial context where an introducing member has a carrying agreement with a clearing member and the clearing member is conducting the allocation. In this scenario, the accounts of the introducing member and its associated persons are subject to the same favorable and unfavorable call provisions as the carrying member's own accounts and associated persons. The introducing member must identify to the carrying member which accounts are accounts in which the introducing member or its associated persons have an interest, enabling the carrying member to apply the Rule 4340(b) and (c) protections correctly.

This provision prevents a structure where an introducing member could exploit the clearing relationship by failing to identify its own interests and those of its associated persons, effectively concealing those interests from the allocation process and potentially receiving favorable treatment or avoiding unfavorable treatment through obscurity. The identification obligation places affirmative responsibility on the introducing member — not merely the carrying member — to ensure the rule's conflict-of-interest protections function properly across the full account population.

The Relationship to Fair Dealing and Rule 2010

Rule 4340's conflict-of-interest provisions are grounded in the same foundational principle that animates much of the FINRA rulebook — that broker-dealers must treat customers fairly and cannot use their position as market intermediary to advantage themselves at customers' expense. Violations of the favorable and unfavorable call provisions directly implicate FINRA Rule 2010's standards of commercial honor and just and equitable principles of trade. A firm that systematically steered favorable call allocations to its proprietary account or its senior executives' personal accounts while customers' positions went uncalled would have committed an offense that Rule 2010 would independently capture even absent Rule 4340, but Rule 4340 provides the specific, operationally precise standard against which conduct is measured.

The allocation procedures requirement of Rule 4340(a) connects to FINRA Rule 3110's written supervisory procedures mandate. Members must have WSPs that specifically address their callable securities allocation process — how partial call notices are received, how the allocation pool is constructed, how the methodology is applied, how allocations are documented, how the favorable and unfavorable call prohibitions are implemented, and how the annual customer notice is generated and delivered. The website publication requirement creates a public compliance commitment that FINRA examiners can verify against actual allocation records during financial and operational examinations.

Examination Relevance and Key Takeaways

FINRA Rule 4340 is tested on the Series 7 General Securities Representative examination in the context of callable securities, bond features, and the fair treatment obligations that apply when issuers exercise call options. The Series 24 General Securities Principal examination tests the rule in the context of supervisory obligations for operations and the specific conflict-of-interest protections applicable to partial call allocations. The rule appears most commonly in examination questions presenting scenarios involving partial bond calls and asking how the member must allocate the called securities when its own proprietary positions are involved.

The key points to retain are these: FINRA Rule 4340 requires every member holding callable securities to establish fair and impartial allocation procedures for partial redemptions or calls and to make those procedures publicly available on its website; members must notify new customers at account opening and all customers at least once per calendar year of how to access the allocation procedures online and that hard copies are available upon request; acceptable allocation methodologies include impartial lottery, pro-rata allocation, or any other objectively fair method — allocations based on customer relationship value or any discretionary preference basis violate the fair and impartial standard; where a redemption is favorable to the called parties, the member must not allocate any called securities to its own accounts or those of its associated persons until all customer positions in that security have been fully satisfied — accounts of clerical and ministerial associated persons may be included in the pool alongside customers for favorable calls; where a redemption is unfavorable to the called parties, the member must not exclude its own positions or those of its associated persons — including clerical and ministerial personnel — from the pool of securities eligible to be called; in introducing and clearing arrangements, the introducing member must identify to the carrying member all accounts in which the introducing member or its associated persons have an interest so the allocation protections can be properly applied; and written supervisory procedures under Rule 3110 must specifically address the callable securities allocation process including the favorable and unfavorable call conflict-of-interest prohibitions.
