The Federal Social Insurance Office (FSIO) ensures the smooth functioning of the social security system, constantly adapting it to the new challenges which arise. It is responsible for old-age and survivors’ insurance (OASI), invalidity insurance, supplementary benefits, occupational benefits (pension funds), loss of earnings compensation for military and civilian service personnel, maternity payments, transition benefits and family allowances. It is also responsible at federal level for family, children’s, youth and old age issues, generational relations and general socio-political issues. The FSIO also initiates and coordinates reciprocal social security agreements with other countries.
