The subscription agreement is the document through which an investor formally applies to invest in a private fund. Most managers treat it as boilerplate — something to be copied from a prior fund's documents and sent out with minimal attention. This is a mistake. The subscription agreement serves three distinct legal functions: establishing investor suitability and qualification under applicable securities exemptions, satisfying regulatory compliance requirements across multiple regimes, and creating contractual commitments that bind the investor to the fund's terms. Getting it wrong exposes the fund to regulatory liability, ERISA complications, FATCA withholding obligations, and potential securities law violations.

The Investor Qualification Function

Every private fund offering depends on a securities law exemption — and that exemption depends on investors meeting specific qualification criteria. The subscription agreement is where those criteria are established through investor representations.

For funds relying on Rule 506(b) under Regulation D, investors must be accredited investors (with an allowance for up to 35 non-accredited but sophisticated investors). The subscription agreement collects the investor's self-certification of accredited investor status through a questionnaire. Under 506(b), the manager may rely on investor representations if it has no reason to believe they are false — the standard is reasonable belief, not verification.

For funds relying on Rule 506(c) — where general solicitation is permitted — self-certification is insufficient. The manager must take reasonable steps to verify accredited investor status, and reliance on investor representations alone does not satisfy the verification requirement. The subscription agreement for a 506(c) offering must collect documentation or direct the verification process: review of tax returns, W-2s, bank statements, or a written confirmation from a licensed attorney, CPA, registered investment adviser, or registered broker-dealer.

For Section 3(c)(7) funds (100 or fewer investors under Section 3(c)(1) is the other common Investment Company Act exemption), investors must be "qualified purchasers" — individuals with $5 million in investments, and institutions with $25 million in investments. The subscription agreement must collect the information necessary to establish QP status, which is a separate and higher threshold than accredited investor status.

ERISA: The 25% Limitation

The Employee Retirement Income Security Act creates significant compliance obligations for funds that accept investment from employee benefit plans — pension funds, 401(k) plans, IRAs, and similar vehicles. If "benefit plan investors" (as defined under ERISA and Department of Labor regulations) own 25% or more of any class of equity interest in a fund, the fund's assets are treated as "plan assets" — meaning the fund manager becomes an ERISA fiduciary and the fund's investments are subject to ERISA's prohibited transaction rules.

Plan asset status is generally undesirable for private fund managers. ERISA fiduciary obligations are stringent, prohibited transaction rules are complex and carry excise taxes, and the administrative burden is significant. Most fund documents are structured to stay below the 25% benefit plan investor threshold.

The subscription agreement must collect ERISA status information from every investor and track it across the investor base. Managers must monitor the 25% threshold on an ongoing basis — not just at initial closing. An investor that is not a benefit plan investor at the time of subscription may become one later through corporate restructuring, and a fund that drifts above 25% without notice is in violation.

The subscription agreement should include representations about ERISA status, the percentage of assets constituting "plan assets" for entities that are themselves funds, and an obligation to notify the manager of any change in ERISA status.

FATCA and CRS: The Tax Documentation Function

FATCA — the Foreign Account Tax Compliance Act — requires the fund to obtain tax status certifications from its investors. U.S. investors must provide a Form W-9 (certifying U.S. person status and taxpayer identification number). Non-U.S. investors must provide the appropriate W-8 form: W-8BEN for individuals, W-8BEN-E for entities, or other variants for specific entity types (such as W-8IMY for intermediaries and flow-through entities).

Without valid W-8 or W-9 documentation, the fund may be required to apply 30% FATCA withholding to U.S.-source payments made to the investor. Subscription agreements should require investors to provide the applicable IRS form and to update it upon request or upon a change in circumstances that renders the prior certification inaccurate.

For funds with non-U.S. investors, the Common Reporting Standard (CRS) — the international automatic exchange of financial information regime — may also require self-certification. CRS applies in over 100 jurisdictions and requires financial institutions (which can include some fund structures) to collect residency information from account holders and report to local tax authorities. The subscription agreement should collect CRS self-certification from non-U.S. investors in affected jurisdictions.

Anti-Money Laundering: Source of Funds and KYC

Private funds are not directly subject to the Bank Secrecy Act's AML program requirements in the same way banks are, but prudent fund management requires investor due diligence. The subscription agreement should collect source of funds and source of wealth representations — where the investor's capital originated and how the investor acquired their overall wealth. These representations serve both AML compliance purposes and provide a documentary basis for the fund's knowledge of its investor base.

For offshore funds or funds accepting non-U.S. investors — common for Miami-based managers with LATAM clients — enhanced due diligence is appropriate for politically exposed persons (PEPs) and investors from jurisdictions identified as higher-risk by FATF. The subscription agreement should include PEP representations and identify jurisdictions that require enhanced diligence.

FinCEN's beneficial ownership rules, applicable to registered investment advisers with AML programs, require identification of natural persons who own 25% or more of a legal entity investor. The subscription agreement should collect this information for entity investors.

The Representations About Fund Documents

A standard subscription agreement includes representations from the investor that it has received and reviewed the fund's private placement memorandum and limited partnership agreement (or operating agreement), that it understands the risks of the investment, and that it is making the investment based on its own review rather than in reliance on any oral representations from the manager. These representations are legally significant: they support the fund's securities law exemptions, and they limit the investor's ability to later claim it was misled about the nature of the investment.

A subscription agreement that simply says the investor "acknowledges receipt" of the PPM — without confirming the investor has reviewed and understood it — is weaker protection than one that contains a substantive representation about the investor's diligence process.

Common Manager Mistakes

Outdated questionnaires. Accredited investor definitions and qualified purchaser thresholds change periodically. A subscription agreement drafted in 2018 may not reflect the 2020 SEC amendments expanding the accredited investor definition to include certain knowledgeable employees and holders of professional certifications. Using outdated forms creates qualification risk.

Inadequate ERISA tracking. Managers who collect ERISA representations at subscription but never aggregate them across the investor base are flying blind on the 25% threshold. A simple spreadsheet tracking each investor's ERISA status and the percentage of each class held by benefit plan investors is a minimum requirement.

Insufficient FATCA documentation. Accepting subscriptions from non-U.S. investors without collecting W-8 forms creates withholding exposure. This is particularly common in funds with LATAM investors where the subscription process is handled informally.

Not updating subscription documents when strategy changes. A fund that originally invested in equity securities but has shifted to lending or hybrid instruments may need to revisit whether its subscription agreement adequately describes the risk profile of the current strategy and whether the applicable securities exemption still fits.
