Bernard Charlès, CEO of Dassault Systèmes and Member of the Board, announces having sold a large number of Dassault Systèmes shares during 4th quarter 2012 and filed the transaction with the AMF (information available on AMF website). The funds generated by the sale will serve to pay his taxes.

Commenting on the announcement, Bernard Charlès declared: “This transaction was necessary, given that Dassault Systèmes shares represent the lion’s share of my belongings; the sole reason for the transaction was to enable me to pay my taxes, according to the new, recently voted fiscal rules. The distribution of my assets is not changing after these transactions and I remain very optimistic about the future of Dassault Systèmes.”
