A source at Credit Suisse Group AG (NYSE:CS) says the bank will cut 100 more jobs at its U.K. investment operation. DealBook cites an anonymous source who did not want to be identified because the plan hasn’t yet been made public. Those cuts will affect the bank’s fixed income and equities divisions, and they are in addition to previous cuts announced as part of Credit Suisse’s cost-cutting program that’s aimed at slashing $4.3 billion in costs by 2015. This latest round of job cuts is expected to take place within the next three months.

In October, Credit Suisse Group AG (NYSE:CS) announced that it would cut 1,000 to 2,000 jobs. Officials at the bank are not commenting on the job cuts. According to market analysts, Credit Suisse is trying to keep up with an economic and regulatory environment that’s tougher than it was last year. The bank has already increased its cost-cutting targets two times this year.
