SUBSCRIBER NOTE: Platts to discontinue Lower Zakum, Umm Shaif assessments from Aug 1

Following feedback on a proposal to discontinue assessments of Abu Dhabi's Umm Shaif and Lower Zakum crude grades announced on April 7, 2014, Platts confirms that it will discontinue assessments of these grades from August 1, 2014. In addition, associated assessments for each of the grades will be discontinued, including yields, netbacks, margins and monthly averages. Both Umm Shaif and Lower Zakum will have been blended together by Abu Dhabi National Oil Corp. to form the new Das Blend crude, which Platts started assessing May 2, 2014. The Umm Shaif and Lower Zakum assessments are currently published on Platts Global Alert pages 2220, 2222 and 1051, and in the Crude Oil Marketwire. The Lower Zakum assessments are published in the Platts assessment database under codes AAKNN00 and AAKUF00, and AAIOT00 and AAILA00 for the monthly OSP of the grade. For Umm Shaif, the daily assessments of the grade are published under the codes AAOUO00 and AAOUP00, with AAIOU00 and AAILB00 for the monthly OSP of the grade.
