Romeo Cerutti, chief legal officer of Switzerland-based Credit Suisse, is one of several senior executives set to step down as the Swiss bank prepares to report first-quarter loss, Reuters and other news outlets are reporting.

The shake-up of senior management is part of new chairman Axel Lehmann's plan to restabilize the embattled bank. Credit Suisse last week said provisions stemming from legal matters that date back more than a decade will force it to increase provisions by around 600 million francs ($631 million) in the first quarter.
