Please be advised that we are moving the publication date of our Market Data Operations Weekly Updates from Mondays to Wednesdays, beginning the week of June 24, 2007.  Recently, a number of issues have arisen after our Monday updates, so we’d like to try a different publication date in the hopes of minimizing the number of notices you receive.

Thank you for your patience while we continue to tweak our process in an effort to make it more efficient.
