BDO is an acronym derived from the names of its three original European founding firms: Binder, Dijker, and Otte.

The Origin of BDO

The name BDO was officially adopted in 1973, stemming from the initial letters of the three key European firms that founded the organization:

  • Binder (from the United Kingdom)
  • Dijker (from the Netherlands)
  • Otte (from Germany)

This unique combination of initials represents the foundational partnership that led to the creation of one of the world's leading global networks of public accounting, tax, and advisory firms.
