Technical problems in Commerzbank DAX Turbos 

Due to technical problems today, Commerzbank is executing own orders. This
results in Commerzbank appearing as both buyer and seller on these orders. This
occurrence has no impact on pricing. 

Commerzbank is currently working on a solution to this technical problem and
apologizes for any inconvenience caused.
