SUBJECT:	Verification of ATOM Tax Data

The Board of Trade Clearing Corporation is preparing for ATOM® 2000 TEFRA processing. As part of this preparation the Clearing Corporation provides brokers the opportunity to review taxpayer addresses and identification numbers maintained in the ATOM system. It is important that you verify tax information in the ATOM system before it is reported to the Internal Revenue Service (IRS). To verify the W-9 information maintained in the ATOM system, the Clearing Corporation has produced a special broker tax information report:

BFR00061 - Broker Tax Data Confirmation

This report will be available in Market Information, Suite 336A, on Friday, January 5, 2001.

To update or change tax information, you will be required to complete a new W-9 form. These forms are available at the Board of Trade Clearing Corporation, Business Systems Office, Suite 1430. All changes must be received prior to 5:00 PM January 11, 2001.
