Interval Fund: Illiquid Assets With Quarterly Exit Windows

Key Takeaways

• Interval funds offer quarterly redemption windows capped at 5–25% of outstanding shares; oversubscribed quarters result in pro-rata partial exits.
• Daily pricing is not daily liquidity; investors who misread this feature were trapped in multiple real-estate and private-credit funds during 2022–2023.
• Investors comparing interval fund yields to BDC yields ignore the gating risk: a BDC allows daily exit at market price, an interval fund does not.
• Total expense ratios above 3%, plus incentive fees on some strategies, mean the portfolio must consistently earn above that before investors benefit.

What It Is

Interval funds are organized under the Investment Company Act of 1940 and operate under SEC Rule 23c-3. The rule requires the fund to make periodic offers to repurchase a set percentage of outstanding shares at NAV. The repurchase schedule, percentage, and pricing mechanics are disclosed in the prospectus.

Shares are bought from the fund at NAV each business day. There is no exchange price. When an investor wants to exit, they must wait for the next repurchase window and tender their shares.

The Intuition

Daily-liquid mutual funds face a mismatch when the underlying assets are slow to sell. Private credit loans, direct real estate, and private equity can take weeks or months to liquidate. Forcing daily redemptions on such portfolios creates a risk that fleeing investors hit the fund during stress, forcing fire sales that harm remaining holders.

The interval fund structure solves that mismatch by fixing the liquidity terms in advance. Investors know up front that they can exit only on quarterly dates and only up to a capped percentage of the fund. In exchange, the portfolio manager can hold less liquid, higher-yielding assets without a run risk.

How It Works

Under Rule 23c-3, the fund's board adopts a fundamental policy that commits to repurchase offers at fixed intervals. The rule allows:

Interval length:    3, 6, or 12 months (quarterly most common)
Repurchase size:    5% to 25% of outstanding shares per offer
Pricing date:       within 14 days after the notice date
Payment:            within 7 days of the pricing date

Most interval funds choose quarterly intervals and a 5 percent repurchase size. That means in any given quarter, the fund commits to buy back at least 5 percent of its shares at NAV. If tender requests exceed the offered size, requests are prorated. An investor who wanted to redeem 100,000 dollars when tenders are oversubscribed may only receive, for example, 60,000 dollars that quarter, with the rest rolled or resubmitted.

Fees are typically higher than in traditional mutual funds, reflecting the cost of managing private-market assets. All-in expenses of 2 to 3.5 percent, plus incentive fees on some strategies, are common.

Worked Example

Consider a hypothetical private-credit interval fund with 1 billion dollars in NAV offering the standard 5 percent quarterly repurchase.

Shares outstanding:           100M shares at $10 NAV
Quarterly repurchase cap:     5% = 5M shares = $50M

Suppose in a quiet quarter 2 million shares are tendered. All tenders are honored at that quarter's NAV.

Now suppose in a stressed quarter, 12 million shares are tendered. The fund can only honor 5 million. The proration factor is 5 million divided by 12 million, or about 41.7 percent. An investor who tendered 100,000 dollars of shares receives about 41,700 dollars at NAV. The remaining 58,300 dollars stays invested unless the investor resubmits at the next window, where they will compete with whoever else wants out.

Over four consecutive oversubscribed quarters, an investor who tendered 100 percent each time might exit roughly 20 percent per year, meaning a full exit could take several years.

Common Mistakes

1. Assuming liquidity equals a mutual fund. The marketing for many interval funds emphasizes daily pricing. Daily pricing is not daily liquidity. Exit is only available at scheduled windows, capped at the repurchase size, and subject to proration.

2. Ignoring the 5 percent cap during stress. In 2022 and 2023, several prominent real-estate and private-credit interval funds saw tender requests exceed the 5 percent cap for multiple consecutive quarters. Investors who planned to exit found themselves rationed out, sometimes for a year or more.

3. Comparing yields to liquid peers without adjusting for illiquidity. An interval fund yielding 9 percent on private credit is not the same proposition as a BDC yielding 9 percent on publicly traded private credit. The BDC gives daily market liquidity (at the cost of price volatility). The interval fund gives NAV liquidity (at the cost of gating risk).

4. Missing the tax reporting nuance. Most interval funds issue a 1099-DIV, not a K-1, because they are registered investment companies rather than partnerships. Distributions are often a mix of ordinary income, capital gains, and return of capital. The character is disclosed in the 19a-1 notice each distribution.

5. Underestimating fees. Total expense ratios above 3 percent, plus incentive fees, are a high hurdle. A portfolio needs to earn above that consistently before any return accrues to the investor.

Frequently Asked Questions

Q: What is an interval fund in simple terms? An interval fund is a registered closed-end fund that does not trade on an exchange. Instead, it offers shareholders the ability to sell shares back to the fund at NAV during scheduled repurchase windows, typically quarterly, with a cap on how many shares the fund will buy in each window.

Q: How does an interval fund affect investment decisions? The illiquidity premium from private credit or real estate holdings may add yield versus liquid alternatives, but investors must accept that exit is gated. In stressed markets, those gates can trap investors for multiple quarters, making the fund unsuitable for any money that may be needed on short notice.

Q: What is a real-world example of interval fund gating? A $1B fund offering 5% quarterly repurchase receives 12M shares tendered in a stressed quarter against a 5M share cap. The proration factor is 41.7%, so a $100,000 redemption request gets only $41,700. The remaining $58,300 must wait for the next quarter and compete again.

Q: How can investors evaluate an interval fund before buying? Check the repurchase percentage in the prospectus (5% is common), read the fund's track record during periods of high redemption demand, compare the all-in expense ratio to public market alternatives, and only invest money with a multi-year horizon that can survive proration.

Q: How is an interval fund different from a traded BDC? A BDC trades daily on an exchange at a market price that can deviate from NAV; exit is immediate but at whatever the market will pay. An interval fund exits at NAV on quarterly dates but caps the volume. BDCs have price volatility risk; interval funds have liquidity and gating risk.
