The Association of Private Bausparkassen, located in Berlin, is one of the oldest German associations, re-founded after World War II and even before the foundation of the Federal Republic of Germany. The association currently represents the interests of all 14 private German Bausparkassen. They have contributed to the rehabilitation of Eastern Germany to a significant extend and have expanded to almost all major Eastern European countries since the early 1990s. Due to the impressive success of the Bauspar system in the countries where it has been established, the association is expecting an increasing interest in the system, especially from developing countries and countries in transition.
