"You can consider these changes to be part of the next step in the implementation of our strategy, a refinement of our investment-bank model by focusing on those areas where we believe we can be successful," Byrne told the news agency.

The closure in Los Angeles will not affect its advice and underwrite debt and equity offerings for corporate clients.
Operating in more than 50 nations, UBS employs approximately 63,000 staff and provides an array of financial products and services, including retail banking, private banking, and wealth management services across the globe.
