SEC Rule 23c-3

Closed-end funds under the Investment Company Act of 1940 do not continuously offer new shares and are not required to redeem shares on demand — their shares trade on secondary markets at prices determined by supply and demand rather than at NAV, and investors seeking liquidity sell their shares to other investors in the secondary market rather than redeeming directly with the fund. This structure allows closed-end funds to invest in illiquid assets without fear of redemption-driven portfolio disruption — the absence of daily redemption obligations is what makes conventional closed-end funds suitable vehicles for less liquid asset classes. However, closed-end fund shares typically trade at persistent discounts to NAV in the secondary market, because the secondary market price reflects both the NAV of the underlying portfolio and the discount that investors demand for bearing the risk of no guaranteed redemption mechanism.

Interval funds operating under Rule 23c-3 represent a structural innovation that combines the investment flexibility of a closed-end fund — ability to invest in illiquid and alternative assets without daily redemption obligations — with a managed, regulated periodic liquidity mechanism that provides investors with reliable but limited redemption access on a scheduled basis. By committing to make periodic repurchase offers of 5% to 25% of outstanding shares at NAV at specified intervals — monthly, quarterly, or semi-annually in practice — interval funds provide enough liquidity to make their shares attractive to investors who would not accept the total illiquidity of a conventional closed-end fund trading at a secondary market discount, while restricting that liquidity to a level manageable for portfolios of genuinely illiquid alternative assets that cannot be liquidated on a daily basis without significant market impact or adverse price discovery.

The investor protection rationale of Rule 23c-3's framework is to ensure that the periodic liquidity offered by interval funds is delivered transparently, predictably, and fairly — that shareholders receive full NAV for tendered shares without dilution or preferential treatment, that the fund provides adequate advance notice of each repurchase opportunity, that shareholders who tender more shares than the fund can repurchase in a single offer are treated on a pro-rata basis rather than on a first-come-first-served basis that would advantage sophisticated investors, and that the fund's fundamental policy commitment to periodic repurchases creates an enforceable obligation protected from opportunistic suspension.

Statutory Authority and Rulemaking History

Rule 23c-3 derives its statutory authority from Section 23(c) of the Investment Company Act of 1940, which permits registered closed-end management investment companies to purchase shares of their own securities — the statutory basis for all closed-end fund share repurchase activity — and Section 38(a)'s general rulemaking authority. Section 23(c)'s authority over closed-end fund share repurchases provides the foundational statutory basis for Rule 23c-3's comprehensive framework governing the terms, timing, pricing, and disclosure mechanics of interval fund periodic repurchase offers.

Rule 23c-3 was originally adopted August 23, 1993 — Investment Company Act Release No. IC-19696 — as the Commission's regulatory framework for the then-emerging interval fund concept, which had been developed by fund industry participants seeking a vehicle that could offer access to less liquid alternative investments within a regulated investment company structure. The rule was amended several times following its adoption — most recently April 18, 2014 — 79 FR 22344, effective July 18, 2014 — which updated the rule's notice, disclosure, and procedural requirements to reflect the commercial evolution of the interval fund market and the growing sophistication of investors accessing alternative assets through this structure. No changes have been made to Rule 23c-3's operative provisions up to the present time.

Key Provisions and Operative Requirements

Rule 23c-3(b) establishes the periodic repurchase offer framework — the provision that defines the interval fund structure and governs its operation. An interval fund operating under Rule 23c-3(b) must have adopted a fundamental policy — a policy that can be changed only by a vote of a majority of the fund's outstanding voting securities, providing the same entrenchment and investor protection as a fundamental investment restriction — establishing the fund's intent to make periodic repurchase offers of its common stock at net asset value at specified intervals.

The fundamental policy must specify three elements: the frequency of repurchase offers, which may be monthly, quarterly, or semi-annually and which must be consistent across all offers; the dates of repurchase request deadlines or the means of determining those dates; and the maximum number of days between the repurchase request deadline and the repurchase pricing date on which the NAV for tendered shares is determined. The fundamental policy's requirement for majority-vote modification protects investors who selected the fund based on its commitment to periodic liquidity from having management arbitrarily curtail or eliminate that liquidity without the shareholder consent that modification of a fundamental policy requires.

The repurchase offer amount — the percentage of outstanding shares the fund offers to repurchase in each periodic offer — must be between 5% and 25% of the total outstanding shares of the fund on the repurchase request deadline. This 5% to 25% range establishes both a floor and a ceiling on the repurchase offer: the 5% minimum ensures that each periodic offer provides meaningful liquidity — a fund offering to repurchase less than 5% of outstanding shares would provide insufficient liquidity to make the interval fund structure a credible liquidity mechanism — while the 25% maximum prevents interval funds from offering so much periodic liquidity that they would effectively be required to maintain liquid portfolios incompatible with their alternative investment mandates.

Where shareholder tenders exceed the repurchase offer amount, the fund must accept shares for repurchase on a pro-rata basis among all tendering shareholders — a critically important investor protection condition ensuring that all shareholders who wish to tender receive equal treatment regardless of the order in which they submitted their tender requests or the sophistication of their access to the fund's repurchase process. Pro-rationing prevents a first-come-first-served dynamic that would systematically advantage institutional investors and financial intermediaries with faster access to the tender process at the expense of retail investors who are slower to respond. A fund may increase its repurchase offer amount by up to 2% above the stated offer amount to avoid the administrative burden of applying pro-rationing when tenders only slightly exceed the offer amount — permitting the fund to accept all tendering shareholders without the pro-rata calculations that marginally oversubscribed offers would otherwise require.

Shareholder notification requirements are among Rule 23c-3(b)'s most operationally significant provisions. The fund must notify shareholders of each periodic repurchase offer no less than 21 days and no more than 42 days before the repurchase request deadline — a 21-to-42-day advance notice window that provides shareholders with adequate time to evaluate the repurchase offer and make an informed decision about whether to tender, while limiting the advance notice period to prevent an excessively long window during which market conditions might change substantially between the notification date and the pricing date. The notification must specify the repurchase offer amount, the repurchase request deadline, the repurchase pricing date, and the payment date — giving shareholders the information necessary to understand the full mechanics of the offer before deciding whether to tender.

Within three business days of sending shareholder notification of a repurchase offer, the fund must file Form N-23C-3 with the Commission. Form N-23C-3 identifies whether the notification pertains to a periodic repurchase offer under Rule 23c-3(b), a discretionary repurchase offer under Rule 23c-3(c), or both simultaneously — creating the Commission's filing record of each repurchase offer event and enabling the examination programme to monitor interval fund compliance with the rule's offer mechanics and timing requirements.

The repurchase pricing date — the date on which the NAV per share is determined for purposes of pricing the repurchase — must be no later than 14 days after the repurchase request deadline, subject to certain adjustments for national holidays and market closures. Tendering shareholders receive the NAV computed on the repurchase pricing date for the shares they tender, regardless of what price prevailed on the date they submitted their tender request — a forward pricing principle parallel to Rule 22c-1's forward pricing requirement for open-end fund transactions, applied to the interval fund's periodic repurchase context. Payment for tendered shares must be made within seven days of the repurchase pricing date, ensuring that shareholders who tender receive the proceeds of their tender within a commercially reasonable time following NAV determination.

Rule 23c-3(b) imposes a leverage restriction that is unique to the interval fund context and directly connected to the repurchase mechanism's integrity. Any indebtedness that an interval fund incurs must mature or be subject to redemption, repayment, or refinancing prior to the fund's next repurchase pricing date. This leverage maturity restriction prevents interval funds from creating debt obligations that might interfere with their ability to fund periodic repurchase offers — a fund that has outstanding indebtedness maturing after the next repurchase pricing date might be unable to pay repurchasing shareholders if the maturing debt consumes the fund's liquid assets at the same time as the repurchase obligation. The leverage restriction ensures that the fund's debt obligations are structured to preserve the liquidity necessary to honour its periodic repurchase commitment.

Suspension or postponement of a periodic repurchase offer is permitted only under narrowly defined emergency circumstances — specifically where the Commission determines that it is in the public interest and consistent with investor protection to suspend redemptions, or where the board determines in a majority vote — including a majority of disinterested directors — that postponement is warranted by specific emergency conditions involving an inability to determine NAV, a market closure or restriction on share trading, or the determination that repurchase would cause a material adverse effect on other shareholders. This narrow suspension authority ensures that interval funds cannot opportunistically delay or cancel repurchase offers except in genuine market emergencies, protecting shareholders from having their expected periodic liquidity denied at the discretion of management.

Rule 23c-3(c) provides for discretionary repurchase offers — offers made at the board's discretion rather than pursuant to the fundamental policy's scheduled intervals. A discretionary repurchase offer may offer to repurchase any amount of outstanding shares and is not subject to the 5% minimum requirement applicable to periodic offers, but must otherwise comply with the notice, pricing, payment, and filing requirements applicable to periodic offers. Discretionary offers provide interval funds with the flexibility to offer additional liquidity between scheduled periodic offer dates when market conditions or shareholder liquidity needs warrant, without committing the fund to a recurring liquidity obligation beyond the fundamental policy's scheduled intervals.

Scope of Application

Rule 23c-3 applies to registered closed-end management investment companies that elect to use the interval fund structure — the rule is not mandatory for closed-end funds generally but is available as an elective framework for closed-end funds that wish to provide periodic NAV-based liquidity to shareholders in lieu of secondary market trading. Interval funds operating under Rule 23c-3 include some of the most commercially significant alternative investment vehicles currently available to non-institutional investors — private credit funds investing in directly originated loans and private bonds, real estate credit funds providing financing to commercial and residential real estate operators, infrastructure debt funds, insurance-linked securities funds investing in catastrophe bonds and reinsurance sidecars, and multi-alternative funds providing diversified access to hedge fund and private equity-like return streams within a registered, regulated vehicle.

The interval fund's registered fund status under the Investment Company Act distinguishes it from unregistered alternative investment vehicles — hedge funds, private equity funds, and other private funds exempt from Investment Company Act registration under Sections 3(c)(1) or 3(c)(7) — and subjects it to the full disclosure, governance, reporting, and compliance requirements applicable to registered funds, including the Rules 2a-5, 22e-4, 38a-1, and 17a-7 provisions that this dictionary has addressed in preceding entries.

Relationship to Related Rules and Regulations

Rule 23c-3's periodic repurchase framework interacts directly with Rule 2a-5's fair value determination requirements. The NAV at which interval fund shares are repurchased on the repurchase pricing date must be computed pursuant to the fund's Rule 2a-5-compliant fair value determination process — the accuracy of the fund's fair value determination for its illiquid and alternative asset holdings is directly determinative of the fairness of the repurchase price to tendering and non-tendering shareholders alike. A fund that overstates the value of its portfolio holdings on the repurchase pricing date delivers an artificially inflated repurchase price to tendering shareholders at the expense of remaining shareholders; a fund that understates values delivers an artificially depressed price that disadvantages tendering shareholders. Rule 2a-5's governance framework — requiring board oversight of the valuation designee's methodology and periodic testing of fair value determinations — is therefore a foundational investor protection requirement for interval funds, where the quality of fair value determinations directly affects the fairness of the periodic repurchase mechanism.

Rule 22e-4's liquidity risk management framework applies to interval funds in a modified form that acknowledges their distinctive liquidity profile. Unlike conventional open-end mutual funds that must maintain liquidity sufficient to meet daily redemption demands, interval funds must maintain liquidity sufficient to fund their periodic repurchase offers at the stated offer amount — a much more predictable and manageable liquidity obligation whose timing and scale are known in advance through the fund's fundamental policy commitment. The Rule 22e-4 liquidity risk management programme for an interval fund must specifically assess the fund's ability to meet each periodic repurchase obligation at the maximum repurchase offer amount without forced portfolio sales at distressed prices.

Rule 38a-1's compliance programme framework applies to interval funds as registered closed-end management investment companies, requiring that the fund's compliance programme specifically address compliance with Rule 23c-3's periodic repurchase mechanics — including the procedures for ensuring accurate repurchase offer amounts are calculated and notified, the processes for administering pro-rata repurchases when tenders exceed the offer amount, the systems for ensuring timely shareholder notification and Commission filing, and the controls ensuring that repurchase pricing reflects accurate NAV determinations.

Amendment History and Regulatory Evolution

Rule 23c-3 has been amended several times since its 1993 adoption, with each amendment reflecting the progressive commercial development of the interval fund market and the regulatory refinements identified through the Commission's examination experience with the growing number of interval funds in operation. The April 2014 amendment updated notice, disclosure, and procedural requirements in response to the growth of the interval fund market and the increasing sophistication of the alternative investment strategies being pursued through the interval fund structure. No changes have been made to Rule 23c-3's operative provisions up to the present time.

The interval fund market's dramatic growth in the years following the 2014 amendment — driven by institutional asset managers launching retail-accessible private credit, real estate, and multi-alternative interval funds to meet retail investor demand for alternatives exposure — has raised ongoing regulatory questions about whether Rule 23c-3's framework remains adequately calibrated to the increasingly complex and illiquid strategies being pursued through the interval fund structure. The Commission's examination programme has monitored interval fund compliance with the liquidity maintenance requirements, fair value determination practices, and periodic repurchase mechanics with increasing intensity as the market has grown, and has engaged with the fund industry on questions about whether the 5% to 25% repurchase offer range remains appropriate for funds pursuing highly concentrated and illiquid private credit and private equity strategies.

Enforcement Context and SEC Action Patterns

Rule 23c-3 enforcement has concentrated on two categories as the interval fund market has grown. The first involves procedural compliance failures — funds that failed to provide the required 21-to-42-day advance notice to shareholders, that filed Form N-23C-3 notifications after the required three-business-day deadline, or that failed to make payment within the seven-day payment window following the repurchase pricing date. These procedural failures are significant because they directly impair the predictability and reliability of the periodic liquidity mechanism that defines the interval fund structure and on which investors relied in selecting it over other investment vehicles.

The second and more commercially significant enforcement category involves fair value determination failures in the context of repurchase pricing — cases where the NAV used to price periodic repurchases was based on stale, methodologically inadequate, or conflicted fair value determinations that did not accurately reflect the current value of the fund's alternative asset portfolio. These cases implicate both Rule 23c-3's pricing requirements and Rule 2a-5's fair value governance framework, and the Commission has treated NAV accuracy at the time of repurchase pricing as a fundamental investor protection obligation that cannot be compromised by the operational difficulty of frequently valuing complex, illiquid alternative assets.

Examination Relevance and Key Takeaways

Rule 23c-3 is examined at the Series 65 level as the regulatory framework governing the interval fund structure — one of the most commercially significant registered fund innovations of the post-financial crisis era. The fundamental policy commitment to periodic repurchase offers, the 5%-to-25% repurchase offer amount range, the majority-vote requirement for modification, the 21-to-42-day advance notice requirement, the 14-day maximum interval between repurchase request deadline and pricing date, the seven-day payment deadline, the pro-rata treatment of oversubscribed offers, and the 2% increase accommodation for marginally oversubscribed offers are the primary operative parameters examined.

The leverage restriction requiring that interval fund indebtedness mature or be redeemable prior to the next repurchase pricing date is examined as the structural liquidity protection ensuring that debt obligations do not impair the fund's ability to meet periodic repurchase obligations. The distinction between the periodic repurchase offer under Rule 23c-3(b) — mandatory pursuant to the fundamental policy — and the discretionary repurchase offer under Rule 23c-3(c) — optional and not subject to the 5% minimum — is a consistently examined structural distinction.

The key points to retain are these. Rule 23c-3 permits registered closed-end management investment companies to make periodic repurchase offers at NAV — the regulatory framework defining the interval fund structure. An interval fund must adopt a fundamental policy — modifiable only by majority vote of outstanding voting securities — specifying the frequency, repurchase request deadline mechanics, and maximum days between request deadline and pricing date. Each periodic offer must be for 5% to 25% of outstanding shares; oversubscribed offers are satisfied on a pro-rata basis with a permitted 2% increase to avoid pro-rationing of marginally oversubscribed offers. Shareholders must receive 21-to-42 days' advance notice; the repurchase pricing date must be within 14 days of the request deadline; payment must be made within seven days of pricing. The fund must file Form N-23C-3 with the Commission within three business days of shareholder notification. Interval fund indebtedness must mature prior to the next repurchase pricing date. Suspension of periodic offers is permitted only in defined emergency circumstances requiring board approval by majority of disinterested directors. Rule 23c-3 was last amended April 18, 2014 and no changes have been made to its operative provisions up to the present time.
