Due diligence is defined as the comprehensive investigation an investor performs before committing capital. In private markets, it happens at two levels: LPs diligencing fund managers before investing in a fund, and GPs diligencing companies before making a deal. Both are non-negotiable.
LP Due Diligence on Fund Managers
When a limited partner evaluates a fund, they are underwriting the GP as much as the strategy. The process typically covers five areas:
Team and organization. Who are the key investment professionals? How long have they worked together? What happens if a key person leaves (see key-person clause)? LPs want stability and alignment.
Track record. Historical performance is the single most scrutinized element. LPs examine IRR, MOIC, DPI, and TVPI at the fund level, then drill into deal-level attribution. They want to know which individuals sourced and led the best-performing investments.
Strategy and market. Is the strategy differentiated? Is the target market large enough? How does the GP source deal flow? LPs compare the stated strategy against the actual portfolio to check for style drift.
Terms and alignment. LPs review the LPA, fee structure, GP commitment, distribution waterfall, and governance provisions. Meaningful GP co-investment signals alignment. Standard terms vary by strategy, but anything that deviates warrants explanation.
Operations and compliance. Fund administration, AML/KYC procedures, valuation policies, cybersecurity, and regulatory standing (RIA or ERA status) all come under review.
The Due Diligence Questionnaire
The DDQ is the standardized document GPs prepare to answer common LP questions. Industry templates from organizations like the Institutional Limited Partners Association (ILPA) cover 200+ questions across investment strategy, team, operations, ESG, and compliance. A well-prepared DDQ saves weeks in the fundraise process.
GP Due Diligence on Investments
When a GP evaluates a potential portfolio company, the scope includes:
- Financial diligence - Historical and projected financials, quality of earnings, working capital analysis, debt structure
- Commercial diligence - Market size, competitive positioning, customer concentration, pricing power
- Legal diligence - Contracts, IP, litigation, regulatory exposure
- Operational diligence - Management team, technology, supply chain, scalability
- Tax and structural diligence - Entity structure, tax exposures, cross-border considerations
For leveraged buyouts, lender diligence runs in parallel since the acquisition depends on debt financing.
The Data Room
All diligence materials live in a virtual data room (VDR). For fundraising, the GP populates the VDR with the PPM, DDQ, audited financials, track record detail, team bios, compliance policies, and ESG documentation. For deal diligence, the target company populates it with financial statements, contracts, and corporate records.
A well-organized data room signals professionalism. A messy one raises red flags before the LP has read a single document.
Frequently Asked Questions
How long does due diligence take for a private fund investment?
LP due diligence on a fund typically takes 60 to 120 days from initial meeting to commitment. Large institutional investors like pension funds may take six months or longer due to internal committee processes. The timeline depends on the complexity of the fund, the LP's familiarity with the GP, and whether it is a re-up or a new relationship.
What is the difference between LP due diligence and GP due diligence?
LP due diligence evaluates the fund manager before committing capital. It focuses on team, track record, strategy, and terms. GP due diligence evaluates a specific deal before making an investment from the fund. It focuses on the target company's financials, operations, market position, and risks. Both are essential but occur at different stages of the investment chain.
What documents are reviewed during fund due diligence?
Core documents include the private placement memorandum (PPM), limited partnership agreement (LPA), due diligence questionnaire (DDQ), audited financial statements, track record data with deal-level attribution, reference letters, compliance policies, and ESG documentation. All of these are typically housed in the fund's virtual data room.
