SUBSCRIBER NOTE: Platts to publish USGC LOOP Sour differentials September 1

S&P Global Platts will begin publishing differentials for LOOP Sour crude traded in cavern at the Louisiana Offshore Oil Port terminal, versus cash WTI and versus Mars, with effect from September 1, 2017.

The LOOP Sour differentials will be published under the following codes:

LOOP Sour M1 vs WTI M1 AALOM01 LOOP Sour M2 vs WTI M2 AALOM02 LOOP Sour M3 vs WTI M3 AALOM03
