Fund Formation and Timelines
MFN provisions govern access to certain terms; co-investment rights govern opportunities beside the fund. The details determine what you owe.
A most-favoured-nation provision can let an investor elect certain rights granted to another investor, subject to the agreed scope, thresholds and exclusions. A co-investment provision can create a right or process for investing alongside the fund. Neither should be understood from its label alone. Review the documents, who is eligible, how elections or allocations work and who tracks the obligations. Counsel can help translate the negotiated rights into a process the firm can actually run.
Five mechanics. The first two are where the negotiation happens and the last two are where the work happens.
The practical consequence for a first fund is that every side letter concession is potentially a concession to everybody at or below that commitment size. A manager who grants something once to close an investor has, in effect, priced it for the rest of the fund. That is the discipline the mechanism imposes, and it is a reason to say no early rather than to negotiate the election later.
The tradeoffs run in one direction: the harder the right, the more capital it can attract and the less flexibility you retain. Read each option with what it costs you.
Four checks, and the first is the one most often skipped.
Co-investors and electing investors both end up with information rights, and the constraint is the same in each case.
A manager cannot grant information they are not free to give. Portfolio company confidentiality, securities law constraints on material non-public information, and obligations to other investors all limit what may be passed on, and Cooley's commentary treats the preservation of confidentiality carve-outs as the manager's own protection rather than as a concession.
The failure mode is a right granted in a side letter, elected by several investors through a most favoured nation provision, and then unperformable because the underlying company will not consent. The cost of that is not legal, it is relational, and it lands every quarter.
Both mechanisms are a proxy for whether the manager understands their own obligations.
It publishes no investor's election, no side letter, and no position any allocator has taken, because those are confidential to the parties.
It also states no market standard for tiering thresholds, election periods, or co-investment terms. The figures it quotes, including the thirty-day election period and the fee and carry arrangement on co-investment vehicles, are one law firm's published observations, attributed and dated, rather than requirements.
This page is educational and general. It is not legal advice. What a most favoured nation provision covers and what a co-investment right obliges you to do are determined by your fund documents and your executed side letters, and they should be settled with fund counsel.
