    • Please note of a minor correction to the symbol used for the publication of the TACO special opening quote in the AID attribute. We incorrectly announced in Clearing Advisory Notice 18-163 published on April 20th, that the AID attribute listed as <AID AltID=”SOQ” AltIDSrc=”112”> which is incorrect. 

      The correct symbol attribute is <AID AltID=”SQ1” AltIDSrc=”112”> which is reflected at the bottom of this notice.

      This notice supersedes Clearing Advisory 18-163 published on April 20, 2018. http://www.cmegroup.com/content/dam/cmegroup/notices/clearing/2018/04/Chadv18-163.pdf
