*** Please Note: ***

* COPS values are weighted averages based on multiple values submitted from participating CBOE TPHs. The weight of each TPH submission is determined by its distance from the median submission.

* MDX will not produce prices on the initial trade date of a new FLEX series; prices for a new series will be posted on the second day such series is listed for trading.

* COPS files are made available to customers via FTP each business day at 3:55 pm Chicago time.
