Key Takeaways
- • Side letters are binding, confidential agreements between fund managers (GPs) and individual limited partners (LPs) that grant specific investors customized terms outside the standard limited partnership agreement (LPA), enabling funds to accommodate institutional capital requirements without modifying terms for all investors.
- • Common side letter provisions address regulatory compliance, internal policy requirements, and bespoke investor needs that the primary LPA does not cover, creating separate contractual obligations that fund administrators must track independently throughout the fund lifecycle to avoid breach of contract.
- • Side letters have become standard practice in private equity and venture capital fundraising, particularly when securing capital from large institutional investors with specific operational or governance requirements that differ from the fund's standard terms.
- • The widespread use of side letters introduces significant operational complexity and administrative burden to fund management, requiring separate tracking systems and governance protocols to manage bespoke obligations alongside general fund operations.
- • Side letters represent a pervasive feature of private equity industry structure, characterized by confidentiality provisions that prevent public disclosure, creating information asymmetries across the investor base and raising governance considerations around transparency and equal treatment of investors.
Summary
Side letters function as supplemental contracts that modify the primary limited partnership agreement (LPA) for individual investors within private equity and venture capital funds. A side letter is a legally binding, confidential agreement between a fund manager (general partner) and a specific limited partner that grants customized rights, terms, or provisions unavailable to other fund investors. This contractual mechanism allows fund managers to secure institutional capital from investors with specialized requirements—including regulatory mandates or internal governance policies—without restructuring the fund's standard terms for the entire investor base.
The practical application of side letters addresses a fundamental tension in institutional fundraising: large institutional investors frequently maintain specific requirements or compliance obligations that standard LPAs do not accommodate. Rather than amend the primary fund agreement, which would necessitate changes to all investor terms, side letters create a separate bargain tailored to individual investor needs. This approach has become standard practice across the private equity industry as a mechanism to close deals with sophisticated capital sources that would otherwise decline fund participation due to operational or regulatory gaps in the LPA.
Common side letter provisions include carve-outs from fee structures, modified reporting requirements, custom governance rights, compliance accommodations, and performance-based terms. These customizations often reflect investor-specific concerns or regulatory frameworks that apply to institutional limited partners but not to other fund participants. Once executed, side letters create discrete contractual obligations that override the LPA for that particular investor, requiring fund administrators to maintain separate tracking systems throughout the fund's lifecycle. Failure to monitor and fulfill these obligations independently can result in contractual breach.
The prevalence of side letters within private equity has generated substantial administrative complexity for fund operations. Fund administrators must implement governance protocols to ensure each side letter's unique provisions are honored separately, including modified fee calculations, distinct reporting schedules, and customized consent or information rights. This fragmentation across the investor base—where different LPs operate under materially different terms—introduces operational risk and requires robust fund administration infrastructure to prevent inadvertent non-compliance.
Side letters remain a defining feature of private equity's structural opacity. As confidential instruments between individual sponsors and investors, side letters are not disclosed publicly and create information asymmetries within fund structures. This secrecy, while protecting competitive commercial relationships, contributes to pervasive opacity within the private equity industry regarding actual investor terms and economic arrangements.
