The predecessor regulations entered into force in 1958 and ensure that persons working and living in different member states do not lose benefits or receive them from multiple states simultaneously, according to official sources. The rules also govern how pensions are calculated when a person has earned pension from multiple member states. The proposal for revised regulations was presented by the European Commission in December 2016.
The agreement covers six areas, though specific changes have not been detailed. It remains unclear when the revised regulations will take effect and which member states supported or opposed the agreement.
