The insurance undertakings active in the motor third party liability insurance branch constitute and administrate together the Swiss National Bureau of Insurance (NBI), which has its own legal personality (art. 74 par. 1 of the Road Traffic Act SVG).

The NBI is established as an association according to art. 60 ff of the Swiss Civil Code (ZGB) (Art. 1 par. 1 of the Constitution of the NBI).

According to the law, the NBI may entrust the execution of its tasks to its members or to third parties and appoint a managing insurer (Art. 76b par. 4 lit. a SVG). The NBI took advantage of this option and appointed a managing insurer for the execution of the technical part of its association tasks. Ever since the formation of the NBI, this task has been executed by Zurich Insurance Company.

The registered office of the NBI is situated at the registered office of the managing insurer in Zurich. Furthermore, the NBI has two registered branch offices, one in Lausanne, and the other in Lugano.
