Dear BATS Europe Participants,

Effective Friday 4th February 2011, BATS Europe will make the following
change to the Symbol Reference Data CSV file available at:

Addition of a matching_unit column - This column indicates the matching
unit for the instrument. Matching units are used to divide instruments
into multicast groups for transmission on the Multicast PITCH market
datafeed.

It is recommended that anyone utilising the BATS Europe Symbol Reference
Data file should confirm proper processing of the additional column
prior to the final release on Friday 4th February 2011.
