Beginning March 25^th, 2003, the expanded version (“PA2”) of the cross-margin customer SPAN® arrays will be using 3 (three) digit Options Clearing Corp. (“OCC”) commodity codes rather than the 2 (two) digit Span-defined codes. The regular version (“PAR”) of the cross-margin arrays will remain unchanged.
