European MTBE normalization process

Platts considers in its European MTBE barge assessment processes transactions where buyer and seller have agreed to a five-day loading range for the barge.

For purposes of measuring the impact of the contango or backwardation in the assessment process, Platts will assign the assessed value of the barge transaction to the middle of the loading date range with effect from December 1, 2009.
