Effective Friday, July 21, 2006 two new fields will be added at the end of the type "P" (Product Master) record in the expanded-format SPAN® file.  They are being added for information only in response to customer requests, and firm implementations of SPAN may ignore them.  The first field is the Valuation Method, in the five bytes beginning in position 117, and the Settlement Method, in the five bytes beginning position 122.  The first field identifies how the cash associated with trade prices, and price moves, is handled, and the second one indicates whether products are cash-settled or physically-delivered. 

The updated layout for the type "P" record is at http://www.cme-ch.com/span/spanl30p.htm.   Beginning Friday, July 21st, the two new fields will be present at the end of the type "P" records in the CBOT-CME SPAN file, available on the Internet at ftp.cme.com/pub/span/data/ccl. 

Effective immediately, the two new fields are available every day in a "test" version of the CBOT-CME SPAN file, available at ftp.cme.com/pub/span/data/ccl/test.  This is the production file except that (a) it has these two new fields and (b) the weighted price risk for Eurodollars and Fed Funds is provided on the type "S" record as method "2" instead of method "3".
