Exchange Fund
An exchange fund is a pooled investment vehicle that lets holders of concentrated single-stock positions swap their shares into a diversified partnership interest without triggering immediate capital gains tax.
Definition
An exchange fund — sometimes called a swap fund or a “Section 721 fund” after the governing tax provision — is a limited partnership or LLC that accepts contributions of appreciated single-stock positions from multiple investors in exchange for a diversified partnership interest. Because the contribution is structured as a partnership contribution under IRC Section 721, it is not a taxable event at the time of the swap.
Exchange funds are used by holders of concentrated, highly appreciated equity positions to achieve diversification without realizing capital gains.
The mechanics
A simplified version:
- An investor contributes $10 million of appreciated public stock — say, Meta shares with a $1 million basis — to the exchange fund
- The fund pools similar contributions from many investors across many stocks
- The investor receives limited partner interests representing a pro-rata share of the pooled portfolio
- No capital gain is recognized at contribution
- After a seven-year lock-up, the investor may redeem their interest in kind — receiving a diversified basket of underlying stocks, with basis carrying over
- Only when those redeemed stocks are later sold is gain recognized (now spread across a diversified portfolio, often allowing for tax-loss harvesting offsets)
The 20% qualifying asset requirement
For the Section 721 non-recognition to apply, the exchange fund must hold at least 20% “qualifying assets” — generally direct real estate. This is why exchange funds maintain a real estate sleeve (often via investments in real estate operating partnerships). The real estate is not the investment thesis; it is a structural requirement.
The seven-year holding period
Partnership interests in exchange funds are locked up for a statutory seven years. Early redemption triggers full gain recognition on the originally contributed shares. The lock-up is the main friction point and the reason exchange funds historically appealed primarily to older holders or those comfortable with a multi-year commitment.
Who uses exchange funds
Typical participants:
- Post-IPO founders and executives with large concentrated positions they cannot fully sell due to lockups, 10b5-1 timing, or public perception
- Long-time public company employees with decades of accumulated RSU and option gains
- Pre-IPO acquirers whose companies were bought for stock and who now hold large positions in a single acquirer
- Multi-generational families holding inherited positions in a single company
Typical minimums are material — historically $5 million and up, sometimes $10 million or $25 million for specific funds.
Why they are “back”
Exchange funds saw a resurgence in the 2020s after a period on the margin, for two reasons:
- Structural cost of hedging has risen — delta-one hedging of concentrated positions (collars, protective puts) has become expensive enough that exchange funds are competitive
- Product evolution — new sponsors have narrowed minimums, streamlined the lockup experience, and improved transparency relative to the older funds

Comparison to other concentrated-stock strategies
Exchange funds are one of several tools for concentrated-stock diversification. Each has different tax and cash-flow profiles:
| Strategy | Diversification | Tax deferral | Liquidity | Typical minimum |
|---|---|---|---|---|
| Outright sale | Immediate | None | Immediate | None |
| Exchange fund | Gradual (7-year) | Full until redemption sale | Locked 7 years | $5M+ |
| Protective collar | None (hedge only) | None | Maintains position | Varies |
| Charitable remainder trust | Full at funding | Deferred / partial | Income stream | Typically $1M+ |
| Donor-advised fund (for appreciated stock) | Full at funding | Fully avoided (gift) | No personal access | Modest |
| Opportunity Zone fund | Full upon realization | Deferral to 2026 + partial exclusion | Locked 10 years for full benefit | Varies |
| Direct indexing with tax-loss harvesting | Gradual | Partial via loss offsets | Full | $250K+ |
Most sophisticated strategies combine several of these — an exchange fund for the core position, direct indexing for loss offsets, charitable vehicles for a giving sleeve, and outright sales for tax-lot-efficient pieces.
Limitations
- Seven-year lock-up removes optionality
- Pooled outcomes — investors take on the performance of the pool, which may underperform the original position
- Fees — management fees and expenses reduce returns; historically material
- Eligibility — the contributed stock must be on the fund’s qualifying list
- Operational complexity — tax reporting is partnership-level and can be involved
- Concentration in redemption — the in-kind redemption basket may still leave significant single-stock positions requiring further diversification
