What a Side-by-Side Account Means in Private Funds

A side-by-side account is a separate investment vehicle that a manager runs alongside a main fund, holding a similar or related strategy but operating under its own terms. It sits next to the commingled fund, not inside it, which means the fees, liquidity, reporting, and even the trade allocation an investor receives can differ from what investors in the main fund get. Anyone reviewing a fund-type product should confirm which vehicle their capital actually sits in, because "managed by the same manager" does not mean "on the same terms." This matters most when a product description blurs the line between a fund and a side vehicle without saying so plainly.

What a Side-by-Side Account Actually Is

A side-by-side account, sometimes called a separately managed account (SMA) when it is set up for a single investor, is a pool of capital that a manager invests using the same or a closely related strategy as their main fund, but as a distinct legal vehicle. The manager runs both at the same time — hence "side by side" — and may buy or allocate similar positions into each.

The key point is legal and economic separation. A side-by-side account is not a share class or sleeve of the main fund. It has its own governing documents, its own investor base (sometimes just one investor), and its own set of terms. Two investors can be exposed to what looks like the same strategy and end up with different outcomes because they are actually in different vehicles.

Side-by-side structures are common in private credit, private equity, and other actively managed strategies where a manager wants to accommodate an investor whose size, mandate, or regulatory situation does not fit the main fund's standard terms. Tokenization does not remove this distinction. A tokenized product can represent an interest in a main fund, in a side account, or in a feeder that only holds an interest in one of the two — the token wrapper does not tell you which.

How a Side-by-Side Account Differs From the Main Fund

The differences are rarely about the underlying strategy itself. They are usually about the terms wrapped around it.

A side-by-side account is not automatically better or worse than the main fund. A large institutional investor might negotiate lower fees and more reporting in exchange for a longer commitment. A strategic partner might get priority allocation into certain deals. The point is that the terms are negotiated separately, and an investor comparing a "return" from one vehicle to another may not be comparing the same thing. Fee and liquidity mechanics work the same way they do in any fund-type RWA product — the terms sit around the underlying performance, not inside it.

Why Managers Set Up Side-by-Side Accounts

Managers create side-by-side vehicles for a handful of recurring reasons, and none of them are inherently a red flag.

• A large investor wants customized terms. A pension fund, sovereign investor, or family office may commit a large enough amount that the manager is willing to negotiate fees, reporting, or liquidity outside the standard fund structure.
• Regulatory or tax constraints. Some investors cannot legally invest through the main fund's domicile or structure, so a parallel vehicle is set up to hold the same or a related strategy in a form that fits their requirements.
• Capacity or strategy limits. A strategy may only support a certain amount of capital before it starts affecting execution or pricing. A side account can let the manager take on additional capital without diluting the main fund's positions.
• Seed or anchor relationships. An early or strategic investor may get a side-by-side account as part of a broader arrangement, sometimes tied to a GP commitment or other alignment terms.

These are legitimate business reasons. The risk for other investors is not that side accounts exist, but that their existence and terms are not disclosed clearly enough to evaluate what it means for the main fund.

Allocation and the Conflict of Interest to Watch

The most important operational question a side-by-side structure raises is allocation: when the manager finds an attractive deal, which vehicle gets it first, or gets more of it?

A manager running both a main fund and a side account has to decide how to split limited opportunities — a specific loan, a specific pre-IPO allocation, a limited supply of a commodity position — between the two. A stated allocation policy (for example, strict pro rata by committed capital, or a rotation system) reduces this conflict. An undisclosed or discretionary policy leaves room for the side account, especially one tied to a large or strategic investor, to receive better access, timing, or pricing than the main fund.

This is not only a fairness question. It affects the return path of the main fund itself. If the best opportunities are consistently allocated first to a side account, the main fund's remaining opportunity set changes, whether or not fund investors ever see the side account's existence. This sits alongside the broader manager due diligence questions worth asking about any fund-type product, and it is a question that a fund's investment committee process should be checking on an ongoing basis, not just at the initial offering.

Liquidity terms create a related conflict. If a side account has more favorable redemption terms than the main fund and both hold similar illiquid positions, the manager may need to sell assets to meet the side account's redemption, which can affect pricing or timing for assets the main fund still holds. This is the same mechanical issue that shows up in any discussion of redemption mechanics in open-end versus closed-end structures, just with an added layer because two separate investor pools are drawing on overlapping assets.

Questions to Ask Before You Invest

Before treating a fund-type product's terms or track record as representative of what you will receive, confirm the following:

1. Am I investing in the main fund, a feeder into the main fund, or a side-by-side account?
2. Does the manager disclose whether side-by-side accounts exist alongside this fund?
3. If side accounts exist, what is the stated allocation policy between them and the main fund?
4. Are the fee and liquidity terms I am being offered the same as, or different from, the main fund's standard terms?
5. Could a side account's redemption terms affect the main fund's asset sales or pricing?
6. Is the track record being shown to me from the main fund, a side account, or a blend of both?

If a product's marketing material cites a track record without specifying which vehicle produced it, that is a gap worth raising before comparing it to any other product. You can review a product's formal documents, structure, and risk disclosures on the BiFu RWA page before deciding whether the terms fit your situation.

FAQ

Is a side-by-side account the same as a fund's share class?

No. A share class is a division within the same legal fund, sharing the same portfolio, while a side-by-side account is a separate legal vehicle with its own documents, investor base, and often its own terms. Two investors in different share classes of one fund own the same underlying assets; two investors split between a main fund and a side account may not.

Does a side-by-side account mean the manager is doing something wrong?

Not by itself. Side accounts are a common and legitimate way for managers to accommodate large investors, regulatory constraints, or capacity limits. The concern is disclosure and allocation policy, not the existence of the structure.

How do I know if an RWA product I am reviewing is a main fund or a side account?

Check the offering or fund documents for the legal name and structure of the vehicle you are actually subscribing to, and compare it to any track record or terms being shown to you. If the documents do not make this clear, that is a question to raise with the manager or platform before you rely on the numbers presented.

Can side-by-side accounts affect the liquidity of the main fund?

Yes, potentially. If a side account has different redemption terms and both vehicles hold overlapping illiquid assets, meeting one account's redemptions can require asset sales that affect pricing or timing for the other. This is one reason allocation and liquidity terms should be reviewed together, not separately.
