Credit Suisse Group Thursday struck an upbeat tone for its private banking arm and its investment bank, and said its strong capital position would allow for surplus cash to be returned to shareholders, according to slides from an investor presentation.

"Capital strength already positions us well to face changing industry regulation while providing flexibility to grow the franchise and achieving attractive returns, with the potential to return excess capital to shareholders," Credit Suisse financial head Renato Fassbind is set to tell investors in Bad Ragaz, Switzerland at a conference sponsored by independent brokerage Helvea.
