SEC Rule 22c-1

A sophisticated investor who knew that the market had risen significantly since the last NAV calculation could submit a purchase order, receive shares at the prior — and now understated — NAV, and immediately benefit from the market appreciation that had occurred before the order was submitted. Conversely, an investor could submit a redemption order immediately before NAV calculation when the market had already declined, locking in the prior higher NAV price while knowing the next calculation would reflect the decline.

This backward pricing dynamic imposed systematic costs on long-term fund shareholders, who effectively subsidised the arbitrage profits of sophisticated market timers. Rule 22c-1 eliminated this dynamic by requiring that every order — purchase, sale, or redemption — be priced at the next NAV computed after the order's receipt, not the prior NAV. 

A purchase order received at 3:45 p.m. for a fund that calculates NAV at 4:00 p.m. Eastern Time will be priced at the 4:00 p.m. NAV, not the prior day's NAV — ensuring that the purchaser pays a price that reflects the market value of the fund's portfolio at the time of the transaction.

The rule's investor protection significance extends beyond its anti-arbitrage function. The forward pricing requirement ensures that every shareholder who submits an order on a given day transacts at the same price — the next computed NAV — creating a uniform, non-discriminatory pricing environment in which no investor receives preferential pricing based on the timing of order submission within the pricing period. 

This uniformity is the foundational fairness principle of the mutual fund pricing model, and Rule 22c-1's enforcement of that principle has operated continuously since its adoption as one of the most durable and commercially critical requirements in registered investment company regulation.

Statutory Authority and Rulemaking History

Rule 22c-1 derives its statutory authority from Section 22(c) of the Investment Company Act of 1940, which authorises the Commission to prescribe the methods by which the current NAV of registered investment company redeemable securities shall be computed for the purpose of distribution, redemption, and repurchase. Section 22(c)'s specific grant of pricing methodology rulemaking authority is the direct statutory foundation for Rule 22c-1's forward pricing requirement and for the NAV computation frequency mandate the rule imposes.

The Commission adopted Rule 22c-1 on October 16, 1968 — Investment Company Act Release No. IC-5519, published at 33 FR 16331 — following its identification of the backward pricing problem as a systematic source of dilution for long-term fund shareholders. 

The rule has been amended several times since its original adoption. The most commercially significant amendment was the November 18, 2016 addition of the swing pricing provision — Investment Company Act Release No. IC-32316, published at 81 FR 82137 — which added Rule 22c-1(a)(3) permitting qualifying open-end funds to adjust their NAV through a swing factor mechanism to pass redemption transaction costs to redeeming shareholders. The most recent formal amendment was April 15, 2022 — 87 FR 22446 — which made conforming technical changes.

The regulatory history of Rule 22c-1 since the swing pricing provision's adoption includes a significant proposed but ultimately withdrawn rulemaking episode. In November 2022, the Commission under Chair Gensler proposed to make swing pricing mandatory for all open-end non-ETF, non-money-market funds and to impose a hard close requirement that would have required all investor orders to be received directly by the fund rather than by intermediaries before the NAV calculation cut-off. 

That proposal generated extensive industry opposition focused on the operational difficulty of the hard close requirement and the concerns about whether swing pricing would cause investor harm in practice. The Commission under Chair Atkins subsequently withdrew the mandatory swing pricing and hard close proposal without adoption, leaving the existing voluntary swing pricing framework of Rule 22c-1(a)(3) intact. No changes have been made to Rule 22c-1's current operative framework up to the present time.

Key Provisions and Operative Requirements

Rule 22c-1(a) establishes the forward pricing requirement and the swing pricing accommodation in a single operative paragraph with multiple sub-components.

The core forward pricing prohibition applies to four categories of persons: registered investment companies issuing redeemable securities; persons designated in the issuer's prospectus as authorised to consummate transactions in such securities; principal underwriters of such securities; and dealers in such securities. Each of these parties is prohibited from selling, redeeming, or repurchasing any redeemable security except at a price based on the current NAV which is next computed after receipt of the tender or order. 

The phrase next computed is the operative requirement — the price at which the transaction occurs must be based on the NAV calculated after the order was received by the fund or its designated agent, not on any previously calculated NAV.

Rule 22c-1(b) establishes the NAV calculation frequency requirement. The current NAV of any redeemable security shall be computed no less frequently than once daily, Monday through Friday, at the specific time or times during the day that the board of directors sets. 

The rule provides limited exceptions to the daily computation requirement: the fund need not compute NAV on days when changes in the value of portfolio securities will not materially affect the NAV, and on days when no security is tendered for redemption and no order to purchase or sell is received. 

In practice, the overwhelming majority of equity and fixed income funds compute NAV once daily at 4:00 p.m. Eastern Time when the major United States stock exchanges close, establishing that closing price as the valuation reference point for the fund's portfolio.

Rule 22c-1(a)(3) establishes the swing pricing accommodation. A registered open-end management investment company — explicitly excluding money market funds regulated under Rule 2a-7 and Exchange-Traded Funds as defined in Rule 22c-1(a)(3)(v)(A) — may use swing pricing to adjust its current NAV per share to mitigate dilution of the value of its outstanding redeemable securities as a result of shareholder purchase or redemption activity, provided it has established and implemented swing pricing policies and procedures satisfying the rule's specific conditions.

The swing pricing mechanism functions by adjusting the NAV at which a fund's shares are priced for a given day's transactions — either upward when net purchases into the fund exceed the swing threshold, or downward when net redemptions exceed the threshold — by a swing factor that reflects the near-term costs the fund would incur to invest or liquidate assets in response to those flows. 

When net redemptions exceed the swing threshold, the fund adjusts its NAV downward by the swing factor before pricing redemption orders, in effect passing the transaction costs of satisfying those redemptions to the redeeming shareholders rather than imposing those costs on the fund's remaining shareholders through the dilution of their NAV. 

When net purchases exceed the threshold, the NAV is adjusted upward, similarly passing investment transaction costs to the purchasing shareholders.

The swing factor must be calculated based only on the near-term costs expected to be incurred by the fund as a result of net purchases or net redemptions on the day the factor is used, including spread costs, transaction fees and charges arising from asset purchases or sales, and borrowing-related costs associated with satisfying redemptions. 

The swing factor may not exceed an upper limit of 2% of NAV per share — a cap designed to prevent the swing pricing mechanism from becoming a punitive levy on redeeming shareholders rather than a cost-allocation mechanism. The swing threshold — the level of net purchases or net redemptions, expressed as a percentage of NAV, that triggers application of the swing factor — must be established in the fund's swing pricing policies and procedures, along with the methodology for calculating the swing factor.

Rule 22c-1(a)(3) requires that any fund using swing pricing adopt written swing pricing policies and procedures that specify the swing threshold or thresholds at which the swing factor applies, the methodology for determining the swing factor, the person or persons responsible for administering the swing pricing programme, and the mechanism for periodically reviewing the policies and procedures and making revisions as appropriate. 

The fund must disclose its use of swing pricing in its prospectus, including the swing threshold or range of thresholds and the upper limit of the swing factor, enabling investors to understand the pricing mechanism that may affect the price at which they purchase or redeem shares.

Rule 22c-1's treatment of Exchange-Traded Funds is structurally significant. ETFs are explicitly excluded from both the forward pricing requirement's practical application and the swing pricing accommodation. 

The ETF exclusion from swing pricing reflects the Commission's recognition that ETFs manage the dilution problem inherent in open-end fund redemption activity through a fundamentally different mechanism — the creation and redemption in-kind process governed by Rule 6c-11 — whose transaction cost allocation does not require NAV adjustment. 

The ETF's exemption from Rule 22c-1's forward pricing requirement, provided by Rule 6c-11's specific exemptive relief, permits ETF shares to trade at market-determined prices in the secondary market rather than at a uniform NAV, the operational distinction that gives ETFs their intraday tradability and price discovery characteristics. Rule 6c-11's exemptive relief from Rule 22c-1 is precisely what enables the secondary market for ETF shares to function — without it, every ETF secondary market transaction would need to occur at NAV, eliminating the ETF's defining characteristic as a market-priced vehicle.

Scope of Application

Rule 22c-1's forward pricing requirement applies to all registered investment companies issuing redeemable securities — the complete universe of open-end mutual funds, money market funds, and Exchange-Traded Funds — along with their principal underwriters, dealers, and any persons designated in the fund's prospectus to consummate transactions. 

The swing pricing provision of Rule 22c-1(a)(3) is available only to open-end management investment companies that are neither money market funds under Rule 2a-7 nor Exchange-Traded Funds under Rule 6c-11 — a framework that limits the swing pricing mechanism to conventional actively managed and index mutual funds that process purchase and redemption orders at a single daily NAV rather than through continuous secondary market trading.

Unit investment trusts are subject to modified application. The core forward pricing principle applies to UIT units, but UITs that hold defined portfolios of eligible securities may value and transact based on the offering side evaluation of those securities determined at any time on the last business day, a pricing accommodation that reflects the definitional and operational characteristics of the UIT structure.

Relationship to Related Rules and Regulations

Rule 22c-1's forward pricing requirement operates as the foundational pricing standard that Rule 2a-5's fair value determination framework serves. 

The accuracy of the NAV that Rule 22c-1 requires to be used for every fund transaction depends entirely on the accuracy of the fair value determinations that Rule 2a-5 governs — a fund that fair values illiquid portfolio holdings inaccurately produces a NAV that misinforms both purchasing and redeeming shareholders, creating the same wealth transfer between shareholder cohorts that Rule 22c-1's forward pricing requirement is designed to prevent. 

The interplay between these two rules makes their compliance frameworks operationally inseparable: Rule 22c-1 requires forward pricing, and Rule 2a-5 ensures that the price being applied is an accurate reflection of portfolio value.

Rule 22c-1's swing pricing exception for money market funds connects directly to Rule 2a-7's comprehensive framework for money market fund NAV calculation, which provides its own pricing methodology through the amortised cost and penny-rounding accommodations that enable stable $1.00 NAV maintenance for qualifying government and retail money market funds, and the floating NAV requirement applicable to institutional prime and institutional tax-exempt money market funds. 

The two rules together govern the complete pricing landscape for registered open-end fund shares — Rule 22c-1's forward pricing requirement establishing the timing principle, and Rule 2a-7's pricing methodology standards establishing the computational framework for money market fund NAV.

Rule 6c-11's exemptive relief from Rule 22c-1 is the legal mechanism that enables the entire Exchange-Traded Fund market structure to function. The ETF's core commercial characteristic — shares tradeable at market-determined prices throughout the trading day — is possible only because Rule 6c-11 exempts ETF shares from Rule 22c-1's requirement that redeemable securities be sold and redeemed only at the next computed NAV. 

Without Rule 6c-11's exemption, ETF shares could not trade at market prices in the secondary market, and the arbitrage mechanism that keeps ETF prices aligned with NAV could not function. Understanding Rule 22c-1 and Rule 6c-11 together is essential to understanding why the ETF's market structure differs fundamentally from a conventional mutual fund's direct purchase and redemption model.

Rule 38a-1's compliance programme framework requires that registered fund compliance programmes specifically address Rule 22c-1 compliance — including the procedures through which fund orders are time-stamped upon receipt, the controls ensuring that orders are priced at the next computed NAV rather than the prior NAV, and, where a fund has adopted swing pricing, the governance and oversight framework through which the swing pricing policies and procedures operate. 

The forward pricing requirement is among the most operationally fundamental Investment Company Act requirements, and adequate compliance programme coverage of Rule 22c-1 is a standard examination focus for the Division of Examinations.

Rule 22e-4's liquidity risk management framework interacts with Rule 22c-1's swing pricing provision — the liquidity classifications that Rule 22e-4 requires funds to maintain for their portfolio holdings are a primary input to the swing factor calculation that swing pricing funds use to determine the cost of satisfying a redemption. A fund whose Rule 22e-4 liquidity classification process accurately reflects the transaction costs associated with liquidating portfolio positions will be better positioned to calculate an accurate swing factor under Rule 22c-1(a)(3) than a fund whose liquidity classifications are imprecise or outdated.

Amendment History and Regulatory Evolution

Rule 22c-1's core forward pricing requirement has been operationally unchanged since its 1968 adoption — the fundamental principle that every fund transaction must be priced at the next computed NAV has remained constant across more than five decades of dramatic changes in the fund industry, market structure, and investor demographics. 

The rule's longevity without substantive amendment to its core requirement reflects both the durability of the anti-dilution principle it embodies and the industry's well-functioning compliance infrastructure built around the 4:00 p.m. Eastern Time NAV calculation that has become the standard throughout the domestic mutual fund industry.

The swing pricing provision added in 2016 represented the first substantive addition to Rule 22c-1 since its adoption. The provision was added following extensive study of the March 2020 COVID-19 liquidity event and with reference to European fund markets where swing pricing has been widely implemented, but it has remained unused — no domestic fund has adopted swing pricing as reported on Form N-CEN — reflecting the operational challenges, investor communication complexity, and market structure differences between the domestic and European fund distribution environments that make swing pricing difficult to implement effectively in the United States.

The withdrawal of the November 2022 mandatory swing pricing and hard close proposal reflects the current Commission's assessment that mandating swing pricing in the domestic market would impose operational and investor protection costs exceeding its benefits in the specific context of the United States fund distribution system, which relies heavily on intermediaries and omnibus accounts through which swing pricing's cost-allocation function cannot be precisely implemented. No changes have been made to Rule 22c-1's current operative framework up to the present time.

Enforcement Context and SEC Action Patterns

Rule 22c-1 enforcement has concentrated on three recurring failure categories. The first is late trading — the practice of accepting purchase or redemption orders after the fund's NAV computation cut-off but pricing those orders at the current day's NAV rather than the next day's NAV, effectively reinstating the backward pricing that Rule 22c-1 was adopted to eliminate. 

The mutual fund market timing scandals of 2003-2004 — which triggered the New York Attorney General's investigation of multiple major fund complexes and the Commission's own enforcement sweep — involved both market timing exploiting stale international NAVs and late trading arrangements in which fund distributors allowed preferred customers to submit orders after 4:00 p.m. 

Eastern Time and receive that day's NAV. The Commission brought enforcement actions against fund advisers, underwriters, and distributing broker-dealers in connection with these violations.

The second category involves intermediary order timing failures — cases where fund orders submitted through broker-dealer intermediaries or omnibus account administrators were incorrectly time-stamped or aggregated in ways that resulted in orders received after NAV cut-off being priced at the current day's rather than the next day's NAV. 

The Commission has addressed these operational failures through enforcement actions against intermediaries and through guidance directing funds to implement controls ensuring that only orders received before NAV cut-off receive that day's NAV.

The third category involves NAV calculation failures — cases where the NAV used for forward pricing was itself inaccurately calculated due to fair value determination failures addressed by Rule 2a-5's framework or due to operational errors in the NAV calculation process.

Examination Relevance and Key Takeaways

Rule 22c-1 is examined at the Series 7 and Series 65 levels as the foundational pricing rule for open-end registered investment company shares. The forward pricing requirement — every transaction priced at the NAV next computed after receipt of the order, not at a prior NAV — is the primary examination concept, together with the daily NAV computation requirement that underlies the forward pricing mechanism's operation.

The ETF exception from Rule 22c-1's forward pricing requirement — enabled through Rule 6c-11's specific exemptive relief — is a consistently examined distinction at both the Series 7 and Series 65 levels, illustrating why ETF shares trade at market-determined prices in the secondary market rather than at a uniform daily NAV. 

The money market fund exception from swing pricing — explicitly excluded from Rule 22c-1(a)(3) alongside ETFs, with money market fund pricing governed instead by the specialised framework of Rule 2a-7 — is examined in the context of understanding the differentiated pricing architecture across the registered fund universe.

The key points to retain are these. Rule 22c-1 requires that all redeemable securities of registered investment companies, including those transacted through principal underwriters and dealers, be sold, redeemed, and repurchased only at a price based on the current NAV next computed after the order is received — the forward pricing requirement eliminating backward pricing and the dilution it causes. 

NAV must be computed no less frequently than once daily at times the board sets, typically 4:00 p.m. Eastern Time for equity and fixed income funds. 

The swing pricing provision of Rule 22c-1(a)(3) permits qualifying open-end management investment companies — excluding money market funds regulated under Rule 2a-7 and Exchange-Traded Funds under Rule 6c-11 — to adjust their NAV by a swing factor not exceeding 2% to pass redemption transaction costs to redeeming shareholders; no domestic funds have adopted swing pricing as reported on Form N-CEN. ETFs are excluded from the forward pricing requirement through the specific exemptive relief granted by Rule 6c-11, enabling secondary market trading at market-determined prices rather than at a uniform daily NAV. Rule 22c-1 was adopted in 1968, the swing pricing provision was added in 2016, and no changes have been made to the rule's operative framework up to the present time.
