Beneficial owner

Also called ultimate beneficial owner, UBO.

Definition

A beneficial owner is the natural person who ultimately owns or controls an interest in a fund, directly or through one or more entities. The term does two jobs in fund operations: identifying the people behind an investing entity for KYC and AML checks, and counting investors against the Section 3(c)(1) limit of 100 beneficial owners.

Example

An LP subscribing for $3M is an LLC owned 60% by one individual, 30% by a family trust and 10% by a second individual. For KYC, the fund's policy sets an ownership percentage above which it identifies owners, so it collects identification for the first individual and for the trust's trustees and settlor, screens each against sanctions lists, and records that the 10% holder sits below its threshold. For the 3(c)(1) count, the LLC is one beneficial owner, unless it was formed for the purpose of investing in the fund or is itself an investment company with a significant stake, in which case the fund looks through to its owners and counts each of them.

Confused with

Holder of record. The name in the fund's register, often a nominee, trustee or entity. Beneficial ownership looks past the name to the person who gets the economics or holds control.

Control person. AML rules also identify an individual with significant managerial control of an entity, such as its managing member, even if that person owns no equity. Many fund KYC forms ask for both.

In practice

The usual failure is screening the entity and stopping. Banks, auditors and institutional LPs expect the chart down to natural persons, and the chart goes stale: a change in a trust's beneficiaries or a transfer of the LLC's units changes who the fund is dealing with. FATCA and CRS use a related concept, controlling persons, with their own definitions.

KYC and AMLKYC (know your customer) and AML (anti-money-laundering) are the checks a fund performs on each prospective limited partner before accepting their subscription: verifying identity and beneficial ownership, screening against sanctions and politically exposed person lists, and documenting the source of funds, with records kept for audit and regulatory review.
3(c)(1) fundA 3(c)(1) fund is a private fund excluded from the definition of investment company under Section 3(c)(1) of the Investment Company Act because its securities are beneficially owned by no more than 100 persons, or 250 for a qualifying venture capital fund with no more than $12 million in aggregate capital contributions and uncalled commitments, and it does not make a public offering.
FATCA and CRSFATCA (the US Foreign Account Tax Compliance Act) and CRS (the OECD Common Reporting Standard) are automatic tax information exchange regimes under which a fund treated as a financial institution must collect tax residency self-certifications from each investor and report certain account holders to its local tax authority, which passes the information to the investor's home jurisdiction.
