The foundation's purpose is to provide occupational pension benefits within the framework of the BVG and its implementing provisions for the employees of the company and economically or financially closely related companies, as well as for their dependents and beneficiaries, against the economic consequences of old age, death, and disability. The affiliation of a related company is made on the basis of a written affiliation agreement, which must be notified to the supervisory authority. The foundation may provide additional benefits beyond the statutory minimum benefits, including support services in cases of need, such as illness, accident, disability, or unemployment. The foundation board shall issue one or more regulations on benefits, organization, management, and financing, as well as on the control of the foundation. It shall define the relationship with the employers, the insured persons, and the beneficiaries in the regulations. The regulations may be amended by the foundation board while preserving the acquired rights of the beneficiaries. The regulations and their amendments must be submitted to the supervisory authority. To achieve its purpose, the foundation may conclude insurance contracts or enter into existing contracts, provided that it is the policyholder and beneficiary itself.
