Side Letters in a Private Fund

The short answer

A side letter is a separate agreement between the fund or its sponsor and a particular investor that gives that investor terms different from the standard documents, such as a lower fee, extra reporting, or a right to transfer. Side letters are common for larger investors. Each one must be consistent with the fund documents and disclosed as the PPM requires, since undisclosed preferences can create conflicts with other investors and anti-fraud exposure.

Common side letter terms

Most favored nation clauses

A most favored nation (MFN) clause lets an investor elect the better terms granted to other investors in comparable circumstances. Sponsors usually limit it by size of commitment, timing and type of investor, so a smaller investor cannot claim a larger investor's special terms. The sponsor should track all side letters and apply the MFN process carefully, since missing an election right can be a breach.

When an investor asks

A first-time sponsor may feel pressure to grant whatever a large investor asks. Resist agreeing to terms that conflict with the fund documents or cannot be delivered. For the underlying document terms see key terms of the governing agreement and what a PPM contains.

Only if the operating agreement allows and the sponsor has authority. Otherwise it may be ineffective or a breach.

Do other investors have to know about side letters?

Not individually, but the PPM should disclose that side letters may be granted and what types.

What is an MFN election?

A right for an investor to choose the more favorable terms given to others, within limits stated in their letter.
