Shareholders holding more than 15% of Credit Suisse stock want to oust the board's risk committee chairman, Andreas Gottschling, after investments imploded, the Financial Times reported on Monday, following a similar call by proxy adviser Glass Lewis. Credit Suisse is raising capital, and has halted share buybacks, cut its dividend and revamped management after the Swiss lender lost at least $4.7 billion from the collapse of family office Archegos, and after the bank suspended funds linked to insolvent supply chain finance company Greensill.
