In practice
Calls fund new investments, fees and fund expenses, and the notice states the amount, purpose and due date. Each investor pays its pro rata share, and the LPA sets the notice period and default remedies, such as forfeiting part of the interest. Funds often bridge calls with a subscription line, which delays the cash needed from investors. Not the same as a distribution.
An example
Round numbers, not a real fundSay an investor has committed $50 million. The fund finds a deal and calls 10%. The investor wires $5 million, and $45 million stays to be called.
Why it matters
Investors have to keep cash ready, and a missed call can carry penalties.
A definition, not advice; where usage varies the entry says so. Something wrong? Tell the desk.
