Four terms recur in private market vehicle evaluations: drawdown, evergreen, interval fund, and BDC. They are often treated as four competing choices on a single menu. They are not. Two of them describe how long a fund lives and how capital enters and exits. The other two describe the legal wrapper a fund uses to make that liquidity promise, and the tax and regulatory obligations that wrapper carries. Separating the two axes lets an advisory firm match a client to the right vehicle at the outset of an evaluation rather than after several iterations.
Key takeaways
- Drawdown and evergreen describe a fund's life cycle. Interval fund and business development company (BDC) describe a fund's legal wrapper. The four terms sit on two different axes, and each axis carries separate consequences for liquidity and tax treatment.
- An interval fund's periodic repurchase offer is a mandatory prospectus-level commitment under SEC Rule 23c-3. A non-traded BDC's liquidity is usually a discretionary tender offer under Exchange Act Rule 13e-4. Both are marketed as evergreen. The distinction becomes material when redemption requests first exceed the stated offer amount.
- Tax reporting tracks the legal wrapper of a fund, not the label. Most interval funds and BDCs elect regulated investment company (RIC) status and issue Form 1099-DIV. Most drawdown funds, and many private evergreen vehicles, are limited partnerships that issue Schedule K-1.
- For a client's IRA or other tax-qualified account, the wrapper can determine whether a fund's leveraged income becomes unrelated to business taxable income. A RIC-taxed vehicle generally blocks that exposure at the entity level. A leveraged partnership generally does not.
- The right structure follows the client's liquidity horizon, account type, and the strategy's own return pattern, not a preference for one wrapper over another.
Two separate decisions inside one term
Every private investment fund a client is offered answers two separate questions. The first question is about fund life: does the vehicle offered have a defined lifetime, or does it run indefinitely? The second question is about the legal wrapper surrounding the fund: is the vehicle a private placement, a registered interval fund, or a business development company?
Two axes: fund life and legal wrapper
| Fixed term (drawdown) | No fixed term (evergreen) |
|---|
| Private placement (Reg D) | Traditional buyout, venture, and private credit funds | Private, non-registered evergreen credit and equity vehicles |
| Registered / regulated wrapper | Uncommon — a registered closed-end structure with a fixed term is rare in practice | Interval funds (Rule 23c-3) and BDCs (Section 54 election) |
Fund life (columns) and legal wrapper (rows) are separate decisions. Evergreen describes the life cycle design; interval fund and BDC describe the wrapper.
The four structures, defined
Drawdown fund
A drawdown fund, also called a traditional closed-end or commitment-based fund, is the dominant structure in traditional buyout, venture, and private credit funds. Drawdown funds are private placement vehicles in which investors commit capital, and the general partner draws down that commitment in tranches (capital calls) over an investment period that typically runs three to five years. The fund then holds and manages those investments through a harvest period and winds down as it exits, usually within a total fund life of ten to twelve years.
Capital is usually illiquid for the life of the commitment: investors have no contractual right to redeem their capital. An investor's only exit routes are a distribution from the fund or a sale of their interest in the secondary market, typically at a discount. Most drawdown funds rely on the private placement exemptions in Section 3(c)(1) or 3(c)(7) of the Investment Company Act, are sold only to accredited investors or qualified purchasers, and are organized as limited partnerships or LLCs that issue Schedule K-1.
Evergreen structure
Evergreen, sometimes called perpetual-life, is not itself a legal wrapper. It is a design choice: an evergreen fund has no fixed termination date, accepts new subscriptions on an ongoing basis, and often reinvests realized gains and income rather than automatically returning them to investors. An evergreen fund can be privately placed or publicly registered.
An evergreen structure funds an investor's capital in full at subscription rather than calling it over time and provides periodic liquidity instead of a fixed exit date. The category includes interval funds, tender offer funds, non-traded BDCs, and non-traded REITs, each layering its own redemption mechanics and regulatory obligations on top of the evergreen design.
Interval fund
An interval fund is a closed-end fund registered under the Investment Company Act of 1940 that commits, in its prospectus, to repurchase a fixed percentage of its outstanding shares at set intervals under SEC Rule 23c-3. Under the rule, that commitment must be between 5% and 25% of shares outstanding, at intervals of three, six, or twelve months, and once adopted, the fund's board can suspend or postpone an offer only in narrow, specified circumstances. If redemption requests exceed the stated repurchase amount, the fund fills them pro rata rather than in full.
Interval funds must also hold liquid assets equal to at least 100% of the repurchase always offer amount, which shapes how much illiquid credit or equity exposure the fund can carry. Because the repurchase commitment is a mandatory, prospectus-level obligation, an interval fund's board carries narrower discretion to skip or resize an offer than the board of a non-traded BDC.
Business development company (BDC)
A BDC is not defined by its liquidity mechanics. It is a specific election under Section 54 of the Investment Company Act of 1940 that a closed-end company makes to invest primarily in U.S. operating businesses. To qualify, a BDC must hold at least 70% of its assets in eligible portfolio companies, which are generally private U.S. operating companies or exchange-listed companies with a market capitalization under $250 million, and must offer those companies significant managerial assistance. In exchange for that mandate, a BDC operates under less restrictive leverage limits than a standard registered closed-end fund, which must maintain 300% asset coverage under Section 18.
A BDC can list on a national exchange, where it trades continuously at a market price that can run above or below its NAV (net asset value), or it can remain non-traded, where it typically offers investors periodic liquidity through a discretionary tender offer under Exchange Act Rule 13e-4.
Tax considerations, structure by structure
Schedule K-1 versus Form 1099-DIV
Drawdown funds and most private evergreen vehicles are organized as limited partnerships or LLCs and file Schedule K-1s. K-1s often arrive later than 1099s, commonly after extended partnership filing deadlines in September or October, which can push a client's own return onto extension. A K-1 can also carry filing obligations in every state where the fund's portfolio companies operate, which for a diversified fund can mean a dozen or more state schedules for a single client.
Interval funds and most BDCs elect regulated investment company (RIC) status under Subchapter M of the Internal Revenue Code. A RIC must distribute at least 90% of its investment company taxable income to shareholders each year to preserve pass-through treatment and typically reports on Form 1099-DIV on the standard individual filing timeline. A separate and stricter rule under Section 4982 requires a RIC to distribute 98% of its ordinary income and 98.2% of its capital gain net income each calendar year; a RIC that falls short owes a 4% excise tax on the shortfall, which is one reason RIC-taxed funds are disciplined about year-end distributions.
1099 reporting is not the same as tax-efficient income
Form 1099 is an administrative simplification, not automatically a more favorable tax outcome. A credit-focused BDC or interval fund earning interest income primarily distributes that income as ordinary dividends, taxed at the client's ordinary income rate, regardless of the 1099 format. K-1 versus 1099 changes when and how a client reports income. It does not change the character of that income by itself.
UBTI and UDFI in qualified accounts
This consideration applies specifically to clients funding a private markets allocation from an IRA, 401(k), or other tax-qualified account. A partnership that borrows money to make investments, or that holds portfolio companies operating as pass-through entities, can generate unrelated business taxable income, specifically unrelated debt-financed income (UDFI), that flows through to a tax-exempt account and triggers a filing obligation and tax liability at the account level, on Form 990-T. A RIC-taxed vehicle is a domestic corporation for tax purposes. Its dividends are generally excluded from UBTI even when the fund uses internal leverage, because the leverage sits inside the corporate entity rather than being attributed to the investor. This is a structural distinction between the interval fund and BDC wrappers and a leveraged drawdown fund held in the same account. The outcome is not automatic in either direction, and the specific fund's tax election and structure warrant confirmation before assuming either result.
A caveat on the word evergreen
Evergreen describes a fund's liquidity design, not its tax election. A private, non-traded evergreen credit fund can still be organized as a partnership and issue a K-1. The specific tax election of any vehicle under review warrants direct confirmation, rather than assuming 1099 treatment follows from the word evergreen.
Understanding these private market investment structures and using the decision tree in practice
No single fund label answers every question a client's situation raises. Working through the questions below in order separates what the client's situation requires from what a given manager is currently raising.
The decision tree
1
Does the client need contractual, periodic access to some portion of this capital within the next one to three years?
Yes
rule out a pure drawdown fund. Continue to question 2.
No
a drawdown fund's fixed term and lack of contractual liquidity are no longer a constraint. Skip to question 4.
2
Does that access need to be reliable and scheduled, or is periodic-but-discretionary access acceptable?
Contractually scheduled
favors an interval fund, where the repurchase offer is a prospectus-level commitment under Rule 23c-3.
Discretionary is acceptable
a non-traded BDC's tender offer program may fit, provided the board can skip or resize an offer.
3
Is the client accessing this allocation through a tax-qualified account, such as an IRA?
Yes
a RIC-taxed vehicle (most interval funds and BDCs) generally avoids passing unrelated business taxable income through to the account. Confirm the specific fund's tax election directly — not every evergreen vehicle elects RIC treatment.
No
UBTI exposure is not a factor, though K-1 versus 1099 reporting still affects the advisory firm's operational load across a book of clients.
4
Does the strategy's return pattern reward patient, concentrated capital, or is it built around a diversified, income-generating portfolio?
[EDITOR: the opening of this answer is missing in the source doc]
better with the underlying investment thesis and avoids forcing a manager to hold cash against redemption risk.
Diversified, income-generating credit
an evergreen wrapper, structured as an interval fund or BDC, is generally designed for this profile.
Illustrative comparison
The table below sets the four structures side by side on the dimensions that may come up in a diligence conversation. The evergreen structure is folded into both the interval fund and BDC columns rather than given its own column, since evergreen is the life cycle design those wrappers implement, not a separate legal structure of its own.
Drawdown, interval fund, and non-traded BDC compared
| Dimension | Drawdown fund | Interval fund (evergreen) | BDC, non-traded (evergreen) |
|---|
| Governing framework | Private placement, Section 3(c)(1) / 3(c)(7); typically unregistered | Registered closed-end fund under the Investment Company Act; Rule 23c-3 | Section 54 election under the Investment Company Act; registered but not exchange-listed |
| Capital funding | Capital calls drawn over a 3–5 year investment period against an unfunded commitment | Fully funded at subscription | Fully funded at subscription |
| Liquidity mechanism | None contractual; distributions only, or a secondary sale, typically at a discount | Mandatory repurchase offer, 5%–25% of shares, set interval, under Rule 23c-3 | Usually a discretionary tender offer under Rule 13e-4; board can skip or resize |
| Typical fund life | 10–12 years (investment, harvest, wind-down) | No fixed term | No fixed term, unless the BDC lists or otherwise exits |
| Tax reporting | Schedule K-1, often on extension; possible multi-state filings | Typically Form 1099-DIV (RIC election) | Typically Form 1099-DIV (RIC election) |
| Leverage limit | Set by the fund's own governing documents and credit facilities; no 1940 Act cap | 300% asset coverage under Section 18 (general registered fund standard) | 200% asset coverage under Section 61(a), or 150% with board/shareholder approval |
| Portfolio requirement | None beyond the fund's stated mandate | None specific to the interval fund rule itself | At least 70% in eligible portfolio companies, plus a managerial assistance offer |
| Typical minimums | $250,000-$1 million or more | $5,000–$25,000 | $5,000–$25,000 or more, fund-dependent |
Illustrative summary of typical features. Terms vary by fund; confirm with the offering documents.
Final takeaways
- Drawdown versus evergreen is a life cycle question. Interval fund versus BDC is a wrapper question. Answer both separately before recommending a structure to a client.
- The drawdown or evergreen wrapper that determines whether a client receives a K-1 or a 1099-DIV. Understand the difference and you can better prepare your clients ahead of tax season.
- 1099 reporting is a paperwork simplification. It says nothing about whether the underlying income is taxed favorably.
- In a tax-qualified account, confirm the fund's specific RIC election before assuming UBTI is or is not a factor. Evergreen design and RIC status are independent choices.
- Match the structure to the client's liquidity horizon, account type, and the strategy's return pattern, in that order. That is what the decision tree tests, not a preference for one wrapper over another.
Frequently Asked Questions
What is the difference between a drawdown fund and an evergreen fund?+
A drawdown fund has a fixed life, typically ten to twelve years, and calls committed capital in tranches over an investment period. An evergreen fund has no fixed termination date, is funded in full at subscription, accepts new subscriptions on an ongoing basis, and offers periodic liquidity instead of a fixed exit date.
Is an interval fund the same as a BDC?+
No. An interval fund is a registered closed-end fund that commits in its prospectus to repurchase 5% to 25% of its shares at set intervals under SEC Rule 23c-3. A BDC is a Section 54 election under the Investment Company Act that requires at least 70% of assets in eligible portfolio companies. A non-traded BDC usually offers liquidity through a discretionary tender offer that its board can skip or resize.
Do evergreen funds issue a K-1 or a 1099?+
It depends on the legal wrapper, not the evergreen label. Most interval funds and BDCs elect RIC status and issue Form 1099-DIV. A private, non-traded evergreen fund organized as a partnership can still issue a Schedule K-1, so confirm the specific fund’s tax election.
Does a 1099-DIV mean the income is taxed more favorably?+
No. Form 1099 simplifies reporting but does not change the character of the income. A credit-focused BDC or interval fund earning interest income distributes it mainly as ordinary dividends, taxed at the client’s ordinary income rate.
Which fund structure works best in an IRA?+
A RIC-taxed vehicle, such as most interval funds and BDCs, generally keeps leveraged income from passing through to the account as UBTI. A leveraged partnership generally does not. Confirm the fund’s specific tax election before assuming either result.
