SUBSCRIBER NOTE: Platts updates volume reflected in Latin America crudes

Following a consultation period which began January 28, 2016, please note that Platts has updated its Latin American crude oil methodology and specifications to align with typical volumes of crude cargoes considered in the assessment process, with effect April 1, 2016.

Through this revised methodology, Platts assessments will reflect the updated typical volumes (in barrels) as follows:

- Escalante (PCAGC00) - 1 million - Roncador (AAQTL00) - 750,000 - Loreto (PCAGH00) - 400,000 - Oriente (PCADE00) - 360,000 - Napo (AAMCA00) - 720,000 - Marlim (AAITF00) - 750,000 - Castilla Blend (AAVEQ00) - 1 million - Vasconia (PCAGI00) - 500,000

Platts will continue to reflect typical volumes of 350,000 barrels for Santa Barbara (AAITD00) and Mesa 30 (AAITB00), and 300,000 barrels for Magdalena (AAWFR00) crude oil.

In addition, Platts will continue to consider other traded volume sizes reported in the market, but such trades may be normalized to reflect the updated volumes.
