According to Gottstein, "These initiatives should also help to provide resilience in uncertain markets and deliver further upside when more positive economic conditions prevail." Financial products Credit Suisse endorses a strategy called bancassurance of trying to be a single company that offers every common financial services product. The investment bank is intended for companies and wealthy individuals with more than 50,000 euro. Credit Suisse developed the CreditRisk+ model of risk assessment in loans, which is focused exclusively on the chance of default based on the exogenous Poisson method. As of 2002 about 20 percent of Credit Suisse's revenue was from its insurance business it gained through the 1997 acquisition of Winterthur.
