Credit Suisse took control of First Boston in 1988. In the mid 1990s, Credit Suisse renamed itself CS First Boston as Credit Suisse First Boston, or CSFB, worldwide. The terms Credit Suisse First Boston and CSFB are generally used to refer to the global investment bank, and not only the original London franchise.
In 2006, Credit Suisse retired the First Boston name to "allow Credit Suisse to communicate as an integrated organization to clients, employees and shareholders.""Re-naming of Credit Suisse First Boston Entities and New Brand to Launch in January 2006", Business Wire, November 18, 2005
