LPA (limited partnership agreement)
Also called Partnership agreement, Fund agreement.
An LPA, limited partnership agreement, is the contract between a fund's general partner and its limited partners that establishes the partnership and sets its terms: commitments and capital calls, management fee, carried interest and the distribution waterfall, term and extensions, investment restrictions, reporting obligations, key person and GP removal provisions.
Example
The LPA for a $50M fund sets a ten-year term with two one-year extensions, a five-year investment period, a management fee of 2% of commitments during the investment period stepping down to 2% of invested cost afterwards, 20% carried interest over an 8% hurdle through a European waterfall, ten business days to fund a capital call, and a limit of 20% of commitments in any one company. Each of those terms is a calculation the administrator runs. In year six, with $38M of cost still invested, the fee is 2% of $38M, or $760,000, against $1,000,000 in year five.
Confused with
Subscription agreement. The subscription agreement is how an investor joins the fund and agrees to be bound by the LPA. The LPA is what they are bound by.
Side letter. A side letter grants one LP terms outside the LPA. The LPA applies to all of them.
PPM. The PPM describes the offering and summarises the terms. The LPA is the binding version, and where the two differ the LPA controls.
In practice
The LPA is the document the auditor reads to test every fee and carry calculation, and the one counsel reads when something goes wrong. Amendments need the consent threshold it sets, often a majority or supermajority of commitments, so a term that turns out to be unworkable is expensive to change after final close.
