Under the 2005 ISDA Master Give-Up Agreement, a fund may “give up” derivatives it has traded with a broker to its Prime broker. It will usually do this because it does not have an ISDA Master Agreement with the broker. Under this arrangement the hedge fund acts at all times as the prime broker’sagent (it may not be a client of the executing broker at all) and never creates its own principal contract with the executing broker, but simply arranges the contract between the executing broker and the prime broker. The PB then puts on a back-to-back trade with the HF under the ISDA Master Agreement between them. Net result: the PB intermediates between EB and HF. Calling this arrangement a “give-up” is something of a misnomer.
