Side letters: which LP negotiations actually move the needle

Every meaningful fundraise generates side letters. An anchor LP, a strategic LP, or a large institutional LP signs the standard subscription agreement and then attaches a side letter that overrides specific provisions of the LPA in that LP's favour. It is normal practice. SEBI does not prohibit it and the LPA typically permits it through a 'side letter authority' clause.

The volume of side letter requests has grown sharply in the last three years. Some of it reflects LPs being more sophisticated about what they can ask for. Some of it reflects template-driven negotiations where the LP's counsel is working from a checklist rather than from the LP's actual concerns.

We help GPs work through side letters during fundraises and the same handful of clauses appear repeatedly. Some of them genuinely matter. Some are negotiating noise. This article sorts which is which.

What a side letter actually does

A side letter is a contract between the fund (or the GP, on behalf of the fund) and a specific LP. It modifies the standard LPA in respect of that LP only. It does not affect other LPs in the fund. The Most Favored Nation (MFN) clause is the mechanism by which other LPs can later opt into another LP's better terms — but only if the MFN is in their own subscription documents.

Common side letter content falls into seven buckets: fee discounts, MFN rights, reporting access, key person provisions, transfer rights, exclusion or opt-out rights, and governance access (observer seats, advisory committee positions).

The clauses that move the needle

Management fee discount. An anchor LP committing ₹100 crore to a ₹500 crore fund typically gets a 25 to 50 basis point discount on the management fee for the life of the fund. On a ten-year fund this is real money — roughly ₹2.5 to ₹5 crore in cumulative fee savings on a ₹100 crore commitment. The GP gives this up because the anchor commitment is what makes first close possible.

MFN rights. The LP gets the right to opt into the better terms of any future LP who joins on more favourable economics. MFN is the single most powerful side letter provision because it compounds: every subsequent LP negotiation has to be evaluated against what it triggers for the MFN holder. We tell GPs to be very careful about who gets MFN. A typical first-fund LPA might have two or three MFN holders. More than that and the GP loses negotiating flexibility.

Key person clause. The LP has the right to suspend further commitment calls if a named investment professional leaves the GP. For Cat II PE funds this is standard. The typical formulation: if the named key person (usually the lead partner) departs, capital calls are suspended for 90 days while LPs vote on whether to continue, dissolve, or replace. This matters because LP commitments are predicated on the GP's investment thesis being driven by specific individuals.

LP-specific reporting. Institutional LPs (insurance companies, pension funds, family offices with sophisticated investment committees) need quarterly reports in a specific format aligned with their internal performance tracking systems. The standard LP report does not work for them. The side letter codifies what additional reporting the LP gets and on what cadence.

The clauses that look important but rarely matter

Governance observer rights. The LP gets the right to send an observer to the GP's investment committee. In ten years of working with funds, we have rarely seen an observer actually attend more than the first one or two meetings. The information asymmetry between the deal team and the observer is too large for the observer to add value. The LP knows this. The clause is symbolic.

Approval rights on conflicts. The LP gets the right to approve transactions where the GP has a conflict of interest. This sounds significant. In practice, conflict transactions are rare in well-run funds and the GP discloses them anyway. The clause adds documentation overhead without changing outcomes.

Pre-emption rights on co-investments. The LP gets the right to co-invest alongside the fund on transactions above a certain size. The right to co-invest is genuinely valuable; the pre-emption (the requirement that the GP offer it first to the LP) is less so. The GP can usually structure around the pre-emption when the co-investment is genuinely scarce.

The clauses worth fighting on

Sole and absolute discretion carve-outs. Some LPs ask for the right to opt out of specific investments if the LP determines (in sole and absolute discretion) that the investment violates the LP's investment policy. This is common for sovereign wealth funds, public pension funds, and ESG-focused LPs. The carve-out makes sense for political or religious restrictions (no alcohol, no defence). It does not make sense for general 'investment quality' opt-outs, which gives the LP a free option on each portfolio company.

Excuse rights with cure mechanism. If an LP excuses itself from an investment, the GP needs to be clear on whether the LP's commitment is reallocated to other LPs (which dilutes their portfolio exposure) or whether the deal size is reduced (which may make the investment uneconomic). The cure mechanism in the side letter resolves this. Without it, every excuse triggers a side conversation with every other LP.

Withdrawal rights. Some LPs (typically those subject to regulatory or tax changes) ask for withdrawal rights if a future regulatory change makes their continued participation untenable. The default position should be a transfer right (the LP can sell its position) rather than a withdrawal right (the fund redeems the LP). Withdrawal damages the fund's NAV because it forces an illiquid asset sale.

The side letter principle we work with: every additional bespoke provision is a future operational cost. The compliance team has to track the variations. The fund administrator has to allocate distributions differently for each LP. After fifteen LPs, with side letters for the top six, the fund's operational complexity becomes the GP's biggest non-investment problem.

How to structure the negotiation

Start the fundraise with a side letter template prepared. The template should pre-approve the three or four side letter terms the GP is comfortable conceding (fee discount on a sliding scale, MFN with named exclusions, standard reporting expansion, key person carve-out). Anchor LPs that take the template terms close faster. LPs that ask for more get scrutinised individually.

The MFN should always have exclusions. Standard exclusions: terms specifically related to the regulatory or tax status of the other LP (a sovereign LP's tax carve-out should not flow through MFN), terms related to commitment size (a ₹200 crore LP's fee discount should not flow to a ₹20 crore LP through MFN), and terms specific to that LP's identity (a brand-name LP's marketing rights).

The negotiation calendar matters. Side letters drafted before first close are reviewed by the GP's counsel as a batch. Side letters drafted after first close get reviewed transactionally and inconsistencies creep in. The MFN tracking spreadsheet that GPs maintain across the fund's life starts on day one of first close.

One letter, many downstream consequences

Side letters are a normal part of fundraising. The mechanics are routine. The downstream operational cost is not. GPs that treat side letters as a routine paperwork exercise end up with a fund that is operationally heavier than it should be. GPs that treat side letters as a structured negotiation, with a template, with pre-approved terms, with explicit MFN exclusions, keep the fund clean. The difference shows up not at first close but in year three, when the compliance team is allocating distributions and trying to remember which LP has which carve-out.
