Weinberger previously served as the global and Americas head of tax. He has been a senior advisory partner for many of EY's largest clients and also served on the global markets executive and global public policy committees.

At the same time, EY is taking the opportunity to simplify its brand name and redesign its logo.

"From 1 July we will be called EY. Shortening our name will provide consistency and ease of use for EY practices and clients around the world. We have also redesigned our logo, reflecting our new brand name clearly in the design. Our new brand name and logo demonstrate clearly and boldly who we are and reflects the traits we need to have the best brand in our profession. Our brand name and logo are important indicators of who we are and what we stand for. Now we are taking the opportunity to strengthen and modernise how we represent ourselves in markets around the world to our clients, our people and the communities in which we operate," said Weinberger.

EY is represented in Switzerland by Ernst & Young, Basel, with ten offices across Switzerland, and in Liechtenstein by Ernst & Young AG, Vaduz.
