ZURICH, Switzerland – Credit Suisse Group on Thursday slashed previously released 2007 profit figures because of an internal investigation into securities valuations and said it doesn't expect to post a profit for the first quarter. Credit Suisse said it has determined that the pricing errors "were, in part, the result of intentional misconduct by a small number of traders. The bank, Switzerland's second largest, said it revised its fourth-quarter net profit downward to 540 million Swiss francs ($541 million) from the previously stated 1.33 billion francs. The full-year net profit figure now forecast is 7.76 billion francs ($7.8 billion), down from the previously stated 8.5 billion francs. "With regard to 2008, including these valuation reductions, Credit Suisse was profitable through the end of February," a company statement said. "However, in light of the difficult market conditions in March, at this time, Credit Suisse believes it is unlikely to be profitable in the first quarter."
