Αρχικά υπέθεσα ότι αναφέρεται σε διάρκεια, κάτι σαν extension clause ή agreement. Συνεχίζοντας λίγο το κείμενο και την έρευνα βρήκα και τον όρο long-form clause ή agreement.
What is a long-form agreement?
The long-form confirmation lists the commercial terms of a transaction that would usually be found in a transaction confirmation, in addition to relationship terms that would typically be found in an ISDA Schedule, such as additional termination events (ATEs) and events of default.
