Calculating your Credit Support Amount
How the IA contributes to the Credit support Amount — being the total amount a Transferor actually has to hand over to its counterparty can be mind-boggling. It pans out like for a given counterparty like so:
- First, take your Exposure - the net mark-to-market value of your Transactions under the ISDA not counting, of course, the CSA itself. Call this E.
- Next, add to E the total Independent Amount you are required to pay the other feller. Call this IAt. E + IAt is the total amount you have to hand over as Credit Support if it weren't for ...
- Any Independent Amount the other dude owes you. This we will call IAr. There’s something faintly absurd both parties exchanging Independent Amounts by title transfer — they net off against each other — but that’s as may be. Stupider things have happened[1].
- Any Threshold that applies to the Transferor - being the minimum MTM amount at which it must pony up variation margin in the first place.
This leaves you with a formula as follows:
- Max[0, E + IAt - (IAr + Threshold.)
Let's plug in some numbers. Say:
Your Credit Support Amount is 10,000,000 + 2,000,000 - (0 + 5,000,000) = 7,000,000. Now whether you have to pay anything or receive anything as a result of that calculation - whether there is a Delivery Amount or a Return Amount, in other words — that depends whether your Credit Support Amount is greater or smaller than your Credit Support Balance.
