Credit Suisse reported a loss in its third quarter 2008 results, driven by significant writedowns in its Investment Bank division. The Investment Bank suffered losses of CHF 3.2 billion due to writedowns of CHF 2.4 billion on exposures to leveraged finance, structured products and commercial mortgages. Trading losses were also incurred due to adverse market conditions in September. However, Credit Suisse's Wealth Management and Corporate and Retail Banking divisions performed resiliently. Credit Suisse also maintained a strong capital position and continued reducing risk exposures in challenging market conditions.
