In the same statement released on Friday, the group also rejected speculation about a potential compensation claim by some foreign banks against Credit Suisse's involvement with the SAirGroup. Media reports have focused on claims that Credit Suisse continued to extend loans to the SAirGroup during 2001, creating the impression that the aviation conglomerate was still worthy of credit. The bank's CEO and chairman, Lukas Mühlemann, was a member of the SAirGroup board of directors at the time. The statement says Mühlemann was not involved at any time in business relations between the Credit Suisse Group and the SAirGroup. It adds that the Rating agency Standard & Poor's rated the SAirGroup as "investment grade" and confirmed the company's creditworthiness. swissinfo with agencies
