Typically, your master confirmation will set out the resolution method for each type of Index Adjustment Event separately — this figures, since depending on the type of Index Adjustment Event, the range of possibilities open to even the most imaginative Calculation Agent will differ. If the underlying Index has been cancelled, you can’t very just well make an adjustment and carry on, because there is nothing left to pay the performance of. It might have been nice had ISDA’s crack drafting squad™ programmed some of this into the definitions, but blessthem, they didn’t, so let us speculate.

• Index Cancellation: This one, we humbly submit, is likely to be Cancellation and Payment, seeing as
• Index Modification: Here Calculation Agent Adjustment doesn’t really make sense (as it implies a one-off adjustment), which falls to Negotiated Close-out, which is really a wishy-washy way of saying Cancellation and Payment, which, for Index Modifications, gives both parties the option to cancel the trade, but not the obligation to.
• Index Disruption: Index disruiption is likely to be transitory — just a temporary failure to publish an index level — and seeing as the Calculation Agent will be hedging by transacting in the underliers of the Index, so it ought to be able to calculate, near enough, an estimated Index level by reference to the closing prices of the constituents. Here, expect Calculation Agent Adjustment.

In all cases, remember: generally the swap dealer (who is Calculation Agent) does not have a dog in the fight. It will accommodate its customer’s wishes as far as it can — that is only good business — as long as those wishes reflect genuinely hedgeable positions. If the dealer can hedge, it will, and will pass on those economics. If it can’t, it won’t, and will account for the liquidation value of its hedges.
