SUBSCRIBER NOTE: Platts to expand basis trades usage in North American natural gas indexes

Following extensive market consultation and feedback, Platts has made the following decisions regarding the use of basis transactions in its daily and monthly indexes:

1. Platts will not include physical basis trades in its daily indexes.

2. Platts will expand the use of physical basis trades in monthly indexes, in all locations, where the price is expressed as a differential to the NYMEX Henry Hub settlement price. Currently, monthly physical basis trades are only included in Platts locations east of the Rocky Mountains. This change will be implemented starting November 26, 2018, for December bidweek.
