Co-investment opportunities are one of the most valuable tools for LP relationships. They allow select investors to increase their exposure to specific deals alongside the main fund. But co-investment vehicles create their own structural, regulatory, and administrative requirements that many managers underestimate.
What a Co-Investment Vehicle Is
A co-investment vehicle is a standalone entity, usually a Delaware LLC, formed alongside your main fund to invest in a specific deal. One or more LPs commit additional capital to the co-invest vehicle, separate from their fund commitment. The co-invest vehicle and the main fund then invest in the same deal, typically on a pro rata basis.
The co-invest vehicle is a separate legal entity with its own operating agreement, its own investors, and its own regulatory filings. It is not a sub-account of the fund. From a legal and tax perspective, it is an independent investment vehicle that happens to invest alongside your fund.
Some managers use a series LLC to house multiple co-invest vehicles under one umbrella, creating a new series for each deal. Others form a fresh standalone LLC for each co-investment opportunity. The right approach depends on your deal volume and investor preferences.
Why GPs Offer Co-Investment
Co-investment rights are a powerful fundraising tool. LPs increasingly expect co-invest access as a condition of committing to a fund. A 2024 survey by Preqin found that 55% of institutional investors consider co-investment rights when evaluating fund commitments.
Offering co-investment lets you write larger checks on attractive deals without increasing the fund’s concentration. If your fund has a 15% single-asset concentration limit and you find a deal that warrants a larger allocation, a co-invest vehicle provides the additional capital without violating fund restrictions.
Co-investment terms are typically more favorable to LPs than main fund terms. Most co-invest vehicles charge no management fee and either no carried interest or a reduced carry (commonly 10% versus 20% in the main fund). This makes co-investment highly attractive to LPs and strengthens your relationship with your largest supporters.
From a competitive standpoint, the ability to offer co-investment differentiates you in a crowded fundraising market. Anchor LPs who receive co-invest rights are more likely to re-up for subsequent funds.
Structuring the Co-Invest SPV
Most co-invest vehicles are formed as Delaware LLCs. The GP of your main fund (or an affiliate) serves as the manager of the co-invest LLC. This gives you operational control while keeping the vehicle legally separate.
The operating agreement for the co-invest vehicle should address fee terms, carried interest (if any), distribution waterfall, expense allocation between the fund and the co-invest, and the manager’s authority over investment decisions. Keep these terms consistent with what you communicated to LPs during the allocation process.
Fee terms vary by manager and deal. The most common structure is zero management fee with 10% to 20% carried interest above a preferred return. Some managers charge no carry at all on co-investments, using them purely as relationship tools. Whatever you choose, document it clearly and apply it consistently.
Allocation methodology determines how the deal is split between the fund and the co-invest vehicle. The most defensible approach is to set the fund’s allocation first based on portfolio construction targets, then offer the remainder to co-investors. Document your allocation methodology in writing before offering the co-investment. This documentation protects you if allocation decisions are ever questioned.
Regulatory Requirements
Each co-invest vehicle requires its own Form D filing with the SEC. The fund’s Form D does not cover the co-invest entity. You must file within 15 calendar days of the first sale of securities in the co-invest vehicle. Missing this deadline risks your Regulation D exemption for that vehicle.
Blue Sky filings are required in each state where co-invest participants reside. These are separate from the fund’s Blue Sky filings. State filing fees typically range from $0 to $600 per state, and requirements vary. Some states require pre-offering notice; others accept post-sale filings.
Co-invest participants must independently qualify as accredited investors (or qualified purchasers, depending on the exemption you are relying on). An LP’s qualification for the main fund does not automatically extend to the co-invest vehicle. You need a separate subscription agreement and accreditation verification for the co-invest.
If you are a registered investment adviser, the co-invest vehicle is a separate client for purposes of Form ADV reporting. You must include it in your regulatory assets under management calculation and disclose it as a private fund on Schedule D of Form ADV.
Operational Considerations
Capital call timing must be coordinated between the fund and the co-invest vehicle. When the deal closes, both entities need to fund simultaneously. Your administrator should issue capital calls to co-invest participants on the same timeline as the fund’s capital call, adjusted for any differences in notice periods.
Distribution waterfalls in the co-invest vehicle run independently from the fund’s waterfall. If the co-invest has different carry terms, the distribution calculations are entirely separate. Your administrator must track and calculate each waterfall independently, even though the underlying deal is the same.
Investor reporting should be coordinated so that LPs who participate in both the fund and the co-invest receive consistent information. Quarterly reports for the co-invest should reflect the same valuation methodology and reporting period as the fund’s reports. Discrepancies in valuation or timing create confusion and erode LP confidence.
Each co-invest vehicle requires its own K-1 preparation and distribution. An LP who participates in both the fund and a co-invest receives two K-1s. K-1s for the co-invest must be prepared on the same timeline as the fund’s K-1s, with a March 15 deadline for calendar-year entities.
If your fund LPA requires an annual audit, consider whether the co-invest vehicle also requires one. Many co-invest operating agreements do not mandate audits, which reduces costs. But some institutional LPs may require audited financials for any vehicle in which they participate. Clarify this expectation before forming the co-invest entity.
Common Mistakes
Not filing Form D for the co-invest vehicle. This is the most frequent regulatory error. Each co-invest entity is a separate issuer conducting a separate offering. The fund’s Form D does not cover it. Budget for the filing and track the 15-day deadline from the date of first sale.
Inconsistent allocation methodology. If you offer co-investment to some LPs but not others, you need a documented, defensible process for making those decisions. Allocating co-invest based on LP relationships alone, without documented criteria, creates a conflict of interest that regulators and fund auditors will flag. Common defensible criteria include commitment size, speed of decision-making, and strategic value.
Failing to document co-invest selection criteria. Your fund’s PPM or LPA should describe how co-investment opportunities are allocated. If you did not address this in your fund documents, create a written co-investment allocation policy before offering your first co-invest. This policy should describe who is eligible, how allocations are determined, and how conflicts are managed.
