SUBSCRIBER NOTE: Most USGC gasoline assessments flip to 11.5 RVP on or around September 9

Please note that the assessments for US Gulf Coast conventional 87 unleaded gasoline (M grade), premium conventional grade gasoline (V grade) CBOB (A grade), Premium CBOB (D grade), and unleaded 89 gasoline will all reflect 11.5 RVP on or about September 9, 2019, after the end of scheduling for Colonial Pipeline's 51st shipping cycle of the year.

This date reflects the RVP transition calendar maintained by Colonial Pipeline as well as feedback from market sources.

RVP transitions for other grades to 11.5 RVP will be addressed in separate subscriber notes.
