Credit Suisse apologized after a report described an event last year where a Black employee dressed as a janitor and people wearing afro wigs took to the stage.

A New York Times report on 3 October said then-Chief Executive Tidjane Thiam walked out of the event after the incident. The event was to celebrate Chairman Urs Rohner’s 60th birthday party, where the Times report detailed a Studio 54-themed party featuring 1970s performers and a number of Rohner’s friends wearing the wigs.
