Credit Suisse Group AG appointed Antoinette Poschung to serve as conduct and ethics ombudswoman, a new role aimed at leading the bank's response to cases of sexual harassment, CEO Tidjane Thiam told the group's employees.

The decision stems from a review of the bank's "global approach to the handling of claims of sexual harassment at Credit Suisse," conducted by Lara Warner and Peter Goerke, co-chairs of the group's conduct and ethics board, as well as general counsel Romeo Cerutti, Thiam said in a memo seen by Reuters.

"They have made clear recommendations which we will be implementing with immediate effect," Thiam said.

Poschung, who is head of HR for corporate functions, will be reviewing all claims of sexual harassment at the bank, along with groupwide training practices and global policies, Reuters reported.
