SUBSCRIBER NOTE: Platts launches methodology change to final monthly natural gas indices for Platts locations

Effective December 1, 2017, S&P Global Platts has launched the following methodology change in final monthly natural gas indices for Platts locations as part of an agreement with Intercontinental Exchange to improve natural gas price transparency and bolster North America price benchmarks.

Final Monthly Indices For Platts Locations:

Platts price reporter trades and non-Platts price reporter ICE Exchange trades are used in these indices. Duplicates will be removed from the ICE trade data and both the buy and sell side of ICE trades will be counted in the indices. For PR trades not done on ICE, only the buy or sell side reported by the price reporter will be counted in the indices. In addition, Platts will continue to screen for outlying data using existing mechanisms as well as verifying trade data that occurs outside of the transparent trading range observed on ICE.
