Launching an interval fund means clearing two SEC gates at once and then running a permanent repurchase program on the schedule the rule dictates. Interval fund SEC registration and Rule 23c-3 requirements work as a package: the fund registers on Form N-2 under both the Investment Company Act of 1940 and the Securities Act of 1933, and it adopts a fundamental policy committing to periodic share buybacks at net asset value on the terms Rule 23c-3 lays out. Everything else, from board composition to liquidity coverage to shareholder notices, flows from those two commitments.
What Rule 23c-3 Requires
Frequency and Offer Size
The fund’s fundamental policy must commit to repurchase intervals of three, six, or twelve months. At each interval, the fund must offer to buy back between 5% and 25% of its outstanding shares at net asset value.1eCFR. 17 CFR 270.23c-3 – Repurchase Offers by Closed-End Companies The percentage and frequency are locked in as a fundamental policy, so a fund committed to quarterly 5% offers cannot quietly switch to annual ones when conditions worsen. Changing the policy requires a majority vote of shareholders.
The Repurchase Timeline
Three dates drive every cycle:
- The repurchase request deadline is the last day a shareholder can submit or modify a tender. After this date, requests cannot be withdrawn.
- The repurchase pricing date is the day the fund calculates the NAV used for the buyback. It can fall up to 14 calendar days after the request deadline.
- The repurchase payment deadline requires the fund to pay tendering shareholders within 7 days after the pricing date.
The full span from request deadline to cash in hand can therefore run up to 21 days, and the NAV a shareholder receives may differ from the NAV on the day of the tender since up to two weeks of market movement can occur in between.
Oversubscription and Pro-Rata Allocation
If shareholders tender more shares than the offered amount plus 2% of outstanding stock, the fund must accept tenders on a pro-rata basis, applying the same proportional reduction to every shareholder regardless of holding size. Oversubscription is common during market stress. A shareholder tendering $100,000 against a 60% pro-rata allocation receives roughly $60,000 in cash and retains shares for the balance.
Repurchase Fees
A fund may deduct a repurchase fee of up to 2% from proceeds, but only if the fee is paid to the fund itself and is reasonably intended to cover the fund’s direct costs of processing the repurchase. Not every fund charges one, so the prospectus is the place to check.
Registration on Form N-2
Before offering shares to the public, an interval fund must register with the SEC under both the Investment Company Act of 1940 and the Securities Act of 1933. The vehicle is Form N-2, filed electronically through EDGAR.2U.S. Securities and Exchange Commission. Investment Company Registration and Regulation Package It’s the same form all closed-end funds use, but interval funds must include additional detail about their repurchase policies.
The form calls for comprehensive disclosure of investment objectives, strategies, risks, and fees. The repurchase policy itself is a fundamental policy of the fund and appears in the registration statement as such.
Continuous Offerings Under Rule 415
Unlike traditional closed-end funds that raise capital in a one-time IPO, interval funds typically register an indefinite number of shares under Rule 415 of the Securities Act.3eCFR. 17 CFR 230.415 – Delayed or Continuous Offering and Sale of Securities This supports continuous share sales, letting the fund take in new investors over time rather than front-loading the capital raise. Many interval funds also charge 12b-1 distribution fees to compensate intermediaries selling shares on an ongoing basis, though this requires exemptive relief from the SEC.
Keeping the Registration Current Under Rule 486
Continuous offerings generate continuous paperwork. The prospectus has to stay current through post-effective amendments. Under Rule 486, an amendment filed by an interval fund operating under Rule 23c-3 becomes effective 60 days after filing. For narrower updates, such as registering additional shares, refreshing financial statements, or making non-material changes, the amendment can take effect immediately on the filing date if the registrant certifies that the amendment qualifies.4eCFR. 17 CFR 230.486 – Effective Date of Post-Effective Amendments and Registration Statements Filed by Certain Closed-End Management Investment Companies A fund can only use these streamlined provisions if a registration statement or post-effective amendment has become effective within the prior two years.
Liquidity Coverage During the Repurchase Window
From the date the fund mails its repurchase notification until the pricing date, it must hold liquid assets equal to at least 100% of the repurchase offer amount.1eCFR. 17 CFR 270.23c-3 – Repurchase Offers by Closed-End Companies Liquid here means assets the fund can sell at approximately their carrying value within the period between the request deadline and the payment date. Cash and short-term government securities qualify; a half-finished real estate project does not.
This is the operational constraint that shapes portfolio construction. A fund with 80% of assets in illiquid holdings cannot offer to repurchase 25% of shares unless the remaining 20% in liquid positions actually covers the full offer. A miscalculation is not just a regulatory problem. The fund also has to pay the shareholders who submitted valid tenders.
Leverage Limits Under Section 18
An interval fund that borrows must maintain asset coverage of at least 300% for debt securities, meaning total assets must be at least three times outstanding debt.5Office of the Law Revision Counsel. 15 USC 80a-18 – Capital Structure of Investment Companies The statute also blocks dividends or other distributions unless the 300% coverage ratio holds after the distribution is accounted for. If illiquid holdings decline and push coverage below the ratio, distributions stop until it recovers.
Shareholder Notifications
Between 21 and 42 days before each repurchase request deadline, the fund must send every shareholder of record and every beneficial owner a written notification. The notice must include:
- The exact percentage of outstanding shares the fund is offering to repurchase
- The repurchase request deadline
- The anticipated repurchase pricing date
- Instructions for tendering shares, including any required forms or electronic submissions
That window is the shareholder’s decision-making period. Missing the request deadline means waiting for the next interval.
Board Governance Standards
Rule 23c-3 requires the fund’s board to meet the fund governance standards defined in ยง 270.0-1(a)(7), which go well beyond a simple majority-independence test:6eCFR. 17 CFR 270.0-1 – Definition of Terms Used in This Part
- At least 75% of directors must be disinterested persons with no significant financial or professional ties to the fund’s adviser. On a three-member board, at least two must be independent.
- An independent director must chair the board and preside over meetings.
- Independent directors select and nominate other independent directors.
- The board must retain independent legal counsel.
- Independent directors meet at least quarterly in sessions where no interested directors are present.
- The board evaluates its own performance and committee structure annually.
Interval fund investors have limited ability to vote with their feet between repurchase windows, so the board carries a heavier oversight role than in a daily-liquidity fund.
Fair Value Oversight Under Rule 2a-5
Because NAV is the price at which repurchases happen, valuation is where 23c-3 compliance most often gets difficult. Many interval fund holdings have no readily available market price. Rule 2a-5 requires the board to determine fair value in good faith, though it can designate the investment adviser as a valuation designee for day-to-day work.7eCFR. 17 CFR 270.2a-5 – Fair Value Determination and Readily Available Market Quotations
When a designee is appointed, the reporting obligations are specific. The designee must provide quarterly reports on material fair value matters, including changes to valuation methodologies and conflicts of interest. Annually, the designee must assess whether the entire valuation process is adequate and effective. And on discovering material errors in NAV calculations or significant deficiencies in the process, the designee must notify the board within five business days.7eCFR. 17 CFR 270.2a-5 – Fair Value Determination and Readily Available Market Quotations
A valuation error moves wealth between departing and remaining shareholders. Overstate NAV by 3%, and tendering investors walk away with money that belongs to the ones who stayed.
When Repurchase Offers May Be Suspended
Mandatory repurchases are the point of the structure, but the rule permits suspension in narrow circumstances. A fund cannot skip or delay a scheduled offer unless a majority of the full board, including a majority of the independent directors, votes to do so, and only for one of these reasons:
- The repurchase would cause the fund to lose its treatment as a regulated investment company under Subchapter M of the Internal Revenue Code.
- The repurchase would cause any listed shares to be delisted.
- The NYSE or the principal market where the fund’s securities trade is closed or trading is restricted beyond normal weekends and holidays.
- An emergency makes it impractical for the fund to sell holdings or to calculate NAV fairly.
- The SEC issues a specific order permitting suspension for investor protection.
If a fund suspends an offer, it must notify shareholders. If the offer is later renewed, a fresh notification must go out. The conditions are intentionally restrictive; the SEC does not want funds treating suspensions as a routine tool.
Ongoing SEC Reporting
Registration is the starting line. Interval funds file continuously across their life, and the volume is substantial.
Form N-PORT collects monthly portfolio holdings data, filed in batches no later than 60 days after the end of each fiscal quarter.8U.S. Securities and Exchange Commission. Form N-PORT The SEC releases data from the third month of each quarter publicly.
Form N-CEN is an annual census due within 75 days of fiscal year-end. It collects fund classification, service provider details, securities lending activity, advisory fees as a percentage of net assets, information about repurchases of outstanding securities, and details on legal proceedings and organizational changes.9U.S. Securities and Exchange Commission. Form N-CEN Combined with continuing post-effective amendments to Form N-2, these filings create a compliance burden well beyond what a typical private fund faces.
A Note on Tender Offer Funds
Tender offer funds look similar but do not fall under Rule 23c-3. Their repurchases are entirely discretionary: the board decides whether to make an offer, how often, and how large, with no minimum frequency, no floor on the percentage offered, and no regulatory liquidity requirement during the offer period. The 5% to 25% offer range, the notification timeline, the 100% liquidity coverage, and the pro-rata allocation rules described above apply only to interval funds registered under Rule 23c-3.1eCFR. 17 CFR 270.23c-3 – Repurchase Offers by Closed-End Companies If a prospectus describes discretionary board-declared tender offers rather than a fundamental policy of periodic repurchases, the fund is running under a different framework.
