Interval Fund vs Tender Offer Fund

Interval Funds & Non-Traded Structures

Definition

An interval fund and a tender offer fund are the two forms of unlisted closed-end fund registered under the Investment Company Act of 1940 that give investors periodic liquidity at net asset value. An interval fund adopts, as a fundamental policy changeable only by shareholder vote, an obligation under Rule 23c-3 to offer to repurchase between 5 and 25 percent of its outstanding shares every three, six or twelve months, must compute NAV at least weekly, and must hold liquid assets equal to the offer amount from the notice date to the pricing date. A tender offer fund makes no such commitment; its board decides each period whether to make a tender offer under Rule 13e-4 of the Exchange Act, for how much (typically up to 5 percent of net assets) and at what valuation date, and may skip a period. Because a tender offer fund can restrict itself to qualified clients it can charge a performance fee, and because it need not hold a liquidity reserve or price weekly it can be fully invested in private assets valued monthly or quarterly. Interval funds dominate the retail semi-liquid credit and real estate market, with $1,000 to $25,000 minimums and daily subscriptions; tender offer funds dominate evergreen private equity, secondaries and private credit sold through wealth platforms to accredited investors. Both are regulated investment companies for tax, issue a 1099, report on Forms N-CSR and N-PORT, and are limited to 33 percent leverage through borrowing.

Why it matters

Wealth platforms present both structures under one label, semi-liquid or evergreen, with the same quarterly liquidity bullet, and the difference only matters at the moment it matters most. In a period of heavy redemptions an interval fund's board has to make the 5 percent offer, has the cash set aside to fund it and prices the fund weekly while the queue forms; a tender offer fund's board can reduce the offer, delay the valuation date or make no offer, and its NAV may be a quarter old. The tender offer structure is not a defect; it is what makes a registered private equity fund possible. But an investor who chose a fund for its quarterly liquidity should know which of the two promises they hold, and the answer is on the first page of the prospectus. Fundrise's lineup shows both in one sponsor: its Income Real Estate Fund is an interval fund that has offered the Rule 23c-3 minimum of 5 percent each quarter, including June 2026, and its Innovation Fund used the tender offer structure until it listed on the NYSE as VCX in 2026.

Common misconceptions

  • •They are not interchangeable names for the same thing. The obligation to repurchase is structural in one and discretionary in the other.
  • •An interval fund's 5 to 25 percent range does not mean funds offer 25 percent. Nearly all adopt the 5 percent minimum and offer exactly that.
  • •A tender offer fund is not less regulated. Both are 1940 Act funds with independent boards, audited reports and leverage limits; the difference is in the repurchase mechanism and who may invest.
  • •Neither provides daily liquidity, and neither is a mutual fund; both are closed-end funds that happen to sell shares continuously.

What Rule 23c-3 requires of an interval fund

A fundamental policy stating the interval (3, 6 or 12 months) and the timing of the repurchase request deadline.

Each offer for not less than 5 percent and not more than 25 percent of outstanding shares; the board may also make discretionary offers no more than once every two years.

Repurchase price at the NAV on the repurchase pricing date, which may be no later than 14 days after the deadline (or the next business day).

Payment within seven days after the pricing date.

A repurchase fee, if any, of no more than 2 percent, paid to the fund to compensate it for the costs of the repurchase.

Liquid assets equal to at least 100 percent of the offer amount from the time notice is sent until the pricing date, with board procedures for maintaining them.

NAV computed no less frequently than weekly, and daily on the five business days before the deadline.

Suspension only in enumerated circumstances, by a majority of the independent directors.

What a tender offer fund's offer looks like

Board resolution each quarter authorizing an offer for a stated percentage of net assets or number of shares.

Schedule TO filed with the SEC containing the offer to purchase, the expiration date and the valuation date; the offer must stay open at least 20 business days and give all holders the same terms.

Tenders may be withdrawn until expiry; after expiry the fund accepts shares, prorating if the offer is oversubscribed.

Price is the NAV on the valuation date, usually quarter end, after expiry; an early repurchase fee may be deducted.

Payment in cash or, in some funds, a non-interest-bearing note payable after the quarter-end NAV is finalized.

Amendment to the Schedule TO reporting shares tendered and accepted; a fund's Schedule TO history on EDGAR is its actual liquidity record.

Decision points for an investor

If the strategy is credit, real estate or income and the fund is open to the public with no performance fee, it is almost certainly an interval fund; the question is the share of Level 3 assets against the 5 percent offer.

If the strategy is private equity or secondaries with an incentive fee, it is a tender offer fund; the question is the Schedule TO record and whether inflows have been funding tenders.

In either case, read the proration history in the shareholder reports: repeated full proration at 5 percent means the fund's holders want out faster than the structure allows.

Check the early repurchase fee and who receives it; a fee paid to the manager rather than the fund is a conflict.

Compare total expense ratio from the N-2 fee table, including acquired fund fees and interest expense, not the management fee alone.

For a tender offer fund, confirm you meet the qualified client or accredited standard and understand that the subscription may be monthly with a notice period.

How investors apply the term

Investors usually apply this term by tying the definition back to the controlling documents and then asking which cash flows, rights, restrictions, or valuation assumptions it changes. A useful review looks at the term alongside fees, leverage, liquidity, reporting frequency, and manager discretion rather than treating it as a standalone concept.

The practical diligence test is simple: identify who benefits if the assumption is wrong, who has control when conditions change, and what evidence the investor receives after closing. Terms that cannot be reconciled to documents, cash movements, and monitoring data should be treated as marketing shorthand until proven otherwise.

Frequently asked questions

What is the main difference between an interval fund and a tender offer fund?
Whether the fund has to buy shares back. An interval fund must make a repurchase offer of at least 5 percent of shares on its stated schedule; that obligation is a fundamental policy and cannot be dropped without a shareholder vote. A tender offer fund may make an offer, and its board decides each quarter. Both usually offer 5 percent, so in calm markets they behave the same; in a stressed market the interval fund still owes the offer and the tender offer fund does not.
Which is better for the investor, an interval fund or a tender offer fund?
For liquidity certainty, the interval fund: a mandatory offer, a liquidity reserve covering it and weekly NAV. For access to private equity and other fully illiquid strategies with an incentive-fee manager, only the tender offer fund structure works, which is why those funds use it. The trade is a firmer repurchase promise against a broader asset menu; the price of the second is that the promise becomes an intention.
Can an interval fund refuse to repurchase shares?
Only within narrow limits. Rule 23c-3 allows a fund to suspend or postpone an offer only in specified circumstances, for example when the exchange is closed, when repurchases would cause the fund to lose its tax status or when a majority of the independent directors determines that an emergency makes it impracticable to sell assets or value them fairly. It can and routinely does offer the 5 percent minimum and prorate when more is tendered, which is the practical limit on interval fund liquidity.
Why do private equity evergreen funds use the tender offer structure?
Three constraints of the interval fund structure are fatal to a private equity strategy: weekly NAV for assets that are valued quarterly, a liquid reserve equal to the offer amount that would sit in cash, and the general bar on performance fees for a fund sold to the public. A tender offer fund limited to qualified clients (about $2.2 million net worth) can charge carried interest, hold private companies valued quarterly and keep the repurchase decision with the board.
How can I tell whether a fund is an interval fund or a tender offer fund?
The prospectus on Form N-2 says so on the cover or in the first paragraph. An interval fund states that it has adopted a fundamental policy to make quarterly (or semiannual or annual) repurchase offers under Rule 23c-3 for at least 5 percent of its shares. A tender offer fund states that it intends or expects to conduct quarterly tender offers, that the board may decide not to, and that shares should be considered illiquid. On EDGAR, a tender offer fund files a Schedule TO for every offer; an interval fund does not.
Do interval funds and tender offer funds have the same fees?
Interval funds typically charge a management fee of 1 to 2 percent with no performance fee, and total expense ratios of 2 to 4 percent once interest on leverage and acquired fund fees are included. Tender offer funds sold to qualified clients commonly charge 1 to 1.5 percent plus an incentive fee of 10 to 15 percent of gains, sometimes over a hurdle, and total expenses that can exceed 4 percent for fund-of-funds structures. Both may deduct an early repurchase fee, up to 2 percent under Rule 23c-3 for interval funds and commonly 2 percent within one year for tender offer funds.
