Side Letters, Share Classes, and Fee Terms: Why Fund Interests Can Differ

Not every investor in a fund has the same deal.

That is true in traditional private funds, and it can still be true when a fund interest is tokenized. The token may make ownership easier to record or transfer within platform rules, but it does not erase the legal terms underneath the fund.

Those terms can differ by share class, subscription date, investor type, fee arrangement, and side letter. For RWA users, that means the product summary is not enough. The documents define the deal.

What a Fund Interest Represents

Learning how to read a fund-type RWA product starts here: a fund interest is a legal claim in a fund structure. It is not the same as owning each underlying asset directly.

Each of the parties in an RWA product has a role. The fund owns or controls the portfolio. The manager makes investment decisions. Investors hold interests in the fund and receive rights defined by fund documents. Those rights usually cover economics, reporting, voting or consent rights, transfer rules, redemption terms, and fees.

Tokenization can change how the interest is represented. It may make the fund interest visible as a token in an account. It may support transfer controls, investor whitelisting, and platform-level records. But the token still points back to legal documents.

The two questions are:

1. What legal interest does the token represent?
2. Do all holders of that interest have the same rights?

Three Ways Terms Can Differ

Fund interests can differ in several ways. The most common are share classes, side letters, and fee terms.

"Same fund" does not always mean "same economics."

Share Classes

A share class is a defined category of fund interest. One fund can have multiple classes.

A fund may create different classes for currencies, investor types, minimum sizes, fee levels, or liquidity terms. One class may charge a lower management fee but require a larger subscription. Another may have a longer lock-up, since redemption mechanics differ between open-end and closed-end funds. Another may be denominated in a different currency.

Share classes are not automatically unfair. They are common fund design tools. But they make comparison harder.

If an RWA product gives exposure to a fund, ask which class you are entering. Do not assume the headline fund strategy applies to every class in the same way.

Check:

• Management fee and performance fee for the class
• Currency of the class
• Minimum subscription and eligibility rules
• Lock-up, redemption, and transfer restrictions
• Expense allocation
• Distribution method
• Voting or consent rights

For a deeper fee guide, see fund fees explained.

Side Letters

A side letter is a separate agreement between the manager and one investor or a small group of investors.

Side letters can cover fee discounts, reporting rights, notice periods, excuse rights, most-favored-nation clauses, transfer permissions, regulatory disclosures, or limits on certain investments.

The risk is not that side letters exist. The risk is not knowing what they can change. Some side letter rights are administrative. Others can affect economics, liquidity, or information access.

Questions to ask:

• Are side letters allowed?
• Can side letters create different economic terms?
• Can they create different liquidity or transfer rights?
• Are other investors notified?
• Is there a most-favored-nation process?
• Are smaller investors excluded from side letter benefits?

An MFN clause may allow certain investors to elect terms granted to others. But MFN rights often have limits. They may apply only above a commitment size or exclude regulatory and tax arrangements. Do not assume MFN makes all investors equal.

Fee Terms

Fees are one of the most visible ways fund interests differ.

Two investors can be in the same broad strategy but pay different total fees because they hold different classes, entered at different times, negotiated different terms, or invested through different access vehicles.

The fee rate is only the first layer. The fee base matters too. A 2% management fee charged on committed capital is different from a 2% fee charged on invested capital or NAV.

The result that matters is net of all relevant costs.

Tokenization Does Not Make Terms Uniform

A common mistake is to treat tokenization as standardization.

Tokenization can standardize some operational parts of a product: whitelisting, account records, transfer rules, and investor workflows. It does not automatically standardize legal rights.

If the underlying fund has multiple classes, the token should map to a specific class or defined interest. If side letters exist, they may sit outside the token record. If fee terms differ, token holders need to know which terms apply to them.

A product page may summarize. The documents define.

The Bottom Line

Fund interests can differ. Share classes can change fees, liquidity, currency exposure, and investor rights. Side letters can give specific investors special terms. Fee arrangements can make two investors in the same broad strategy receive different net outcomes.

For RWA users, the rule is direct: do not stop at the product summary. Read the class terms, fee section, side letter disclosure, and transfer rules. You can review RWA product information at Bifu RWA.

The fund name tells you the strategy. The documents tell you your deal.

FAQ

Do all investors in the same fund get the same terms?

Not necessarily. Investors can hold different share classes, subscribe at different times, or have a side letter that grants them different fees, reporting rights, or transfer terms. The fund name and headline strategy describe the strategy, not each investor's specific deal.

What is a side letter in a fund investment?

A side letter is a separate agreement between the manager and one investor, or a small group of investors, that can cover fee discounts, extra reporting, notice periods, or other rights outside the main fund documents. Some side letter terms are administrative, but others can change economics or liquidity, so it matters whether such agreements exist and who they cover.

Does a most-favored-nation (MFN) clause guarantee equal treatment?

No. An MFN clause may let certain investors elect terms granted to others, but it often applies only above a minimum commitment size and can exclude regulatory or tax arrangements. Smaller investors are frequently outside the MFN process entirely.

Does tokenizing a fund interest standardize the terms across investors?

No. Tokenization can standardize operational parts of a product, such as whitelisting, account records, and transfer workflows, but it does not automatically standardize the underlying legal rights. If the fund has multiple share classes or side letters, the token still maps back to whichever specific terms apply to that holder.
