An index option is a call or put option contract in which the underlying asset is an index of any sort. For example, in a call, a market participant may buy the right to an index on or before the expiration date at a certain strike index.

Some options, both derivatives and non-derivatives, related to physical delivery of gas or electricity are traded on the basis that the option may be exercised against an index or reference price upon its publication.

As the Agency does not intend to publish a list of indexes because most of them are publicly available and can be readily accessed, the Agency recommends that reporting parties use those indexes exactly as advertised by the publisher.

If the index is not public, then market participants should make best efforts to minimise any discrepancy with the other market participant when reporting this information. Market participants may consider using the following convention:

[commodity]-[delivery area]-[delivery period]-[index name]-[publisher name]

1. GAS-NBP-DAYAHEAD-INDEX-PUBLISHERNAME

2. GAS-EU- FRONTMONTH-AVERAGEPRICE-PUBLISHERNAME
