SUBSCRIBER NOTE: Group 3 gasoline reflects 13.5 RVP on or around October 31

Please note that S&P Global Platts Group 3 suboctane and premium suboctane gasoline assessments will reflect 13.5 RVP on or around October 31, 2018.

Platts reflects next-business-day injections into the Magellan Pipeline at Tulsa, Oklahoma, in Group 3 gasoline assessments.

The change is due to seasonal adjustments to RVP levels as required by Magellan Midstream Partners' pipeline system.
