x-flat

4. „Dirty price“ mark

As of January 23rd , 2006, WM („Wertpapier-Mitteilungen“) has introduced the following
new keys for field „GD311“ (Specialties along with interest resp. divident payments):
· V interest rate variable and x-flat
· W x-flat, additional interests possible
· X x-flat
Along with these marks, not only will the accrued interest calculation be suspended in
XONTRO, but beyond that any correction of the market value based on indexed coefficients,
pool factors, or any other factors will not be performed (“dirty price”). The mark
may be set along with insufficient base data delivery by the instrument issuer, or, if the
instrument demands calculations that are not available for XONTRO. This last instance is
true for the so called “Argentina Bonds”, i.e. for bonds with “cash paid interest” and
“capitalization interest”.
The mark will be introduced beginning March 6th , 2006. In a first step, the instruments
identified by their WKNs: A0DUDE, A0DUDF, A0DUDG, A0DUDH, and A0D27J will be
affected.
