Credit Suisse Group said Thursday that first-quarter net profit rose 5%, on healthy fixed-income results at its investment bank and lower costs, as it voiced confidence in its outlook.

The Zurich-based bank said net profit for the three months to March 31 rose to 2.1 billion Swiss francs ($1.96 billion), from two billion francs a year earlier. The result beat analyst estimates, which averaged 2.06 billion francs in a Dow Jones Newswires poll.
