Transaction - ISDA Provision
What exactly counts as a Transaction under an ISDA Master Agreement is a matter of some moment, because it will determine what you need to take into account when applying close-out netting, and (unless you’ve specified a narrower range of Covered Transactions) the values you need to calculate when making collateral calls under a 1995 CSA.
Unusually, for a document so outrageously verbose in most other respects, the ISDA Master Agreement has little to say on the subject, the 1992 ISDA leaving it entirely to the preamble:
... one or more transactions (each a “Transaction”) that are or will be governed by this Master Agreement.
And the 2002 ISDA not going much further.
“Transaction” has the meaning specified in the preamble.
The 2002 ISDA Equity Derivatives Definitions also define “Transaction”, to no apparent point.
