A capital call is a formal request from a fund's General Partner to its Limited Partners to fund a portion of their previously committed capital, typically issued as investment opportunities arise rather than collecting the full commitment upfront.
Why It Matters
Capital calls are why private fund commitments require active liquidity management on the LP side — an institution that commits $50M to a fund doesn't write that check on day one, but needs to be ready to fund calls (often with 10 business days' notice) over the following years, which is a genuine operational and cash-planning discipline for allocators managing dozens of fund relationships simultaneously.
How It Works in Practice
- 1LPs sign a capital commitment at fund closing but fund it incrementally as the GP calls capital for specific investments or fees
- 2Capital call notices specify the amount due, the purpose, and the deadline (commonly 10 business days)
- 3Failure to fund a capital call on time (an LP default) typically triggers significant penalties under the LPA, including forfeiture of prior contributions in severe cases
- 4Capital call credit facilities (subscription lines) let GPs borrow against LP commitments to fund deals faster, delaying actual capital calls — a practice that affects reported IRR and has drawn LP scrutiny
Common Pitfalls
LPs that overcommit across multiple funds without modeling correlated capital call timing (many GPs call capital during similar market windows) can face genuine liquidity strain
Heavy use of subscription lines by a GP can inflate a fund's headline IRR by shortening the period capital is technically "at work" — LPs increasingly ask for both subscription-line-adjusted and unadjusted IRR
Missing a capital call deadline has real, sometimes severe, contractual consequences, not just a late fee
