Título Who we are

The Constitutional Amendment nº. 20/98, the so-called Social Security Plan Reform, that introduced changes in the specific regimes of the civil servant pension plan programs, including the possibility to create Capitalized Funds to cover these regimes.

The Rio de Janeiro State Government, aware of its duty to provide payment for social security benefits, owed to its civil service employees and their dependents, without compromising funding of its core duties (providing services and infrastructure to the population in general), implemented the measures necessary for organization, and operation of the new capitalized regime to fund its own State Employee Social Security Benefit Program.


Through enactment of Law nº. 3189, of February 22, 1999, the Rio de Janeiro State Single Social Security Fund - RIOPREVIDÊNCIA, an independent self-governing public entity, for the purpose of managing fund´s financial assets, in order to provide funding for payment of stipends, pensions and other social security benefits.

Following the legal requirements set forth in the Constitutional Amendment nº. 41 of December 19, 2003, Law nº. 5109, of October 15, 2007 determined the end of the Rio de Janeiro State Social Security Institute - IPERJ, transferring to RIOPREVIDÊNCIA the authority to authorize, Manage and pay the social security benefits defined in state law, which deals with the social security regime of Rio de Janeiro State civil servants and their dependents. On December 11, 2007, Law nº. 5154 changed Attachments II and III of Law nº. 5109, of October 15, 2007. 



To provide excellent services to our clientele (active and inactive civil servants, pensioners and dependents), with efficient service, credibility, respect and social responsibility, with transparent and effective asset management, to meet current and future social security benefits and contribute to a state fiscal management.



To be the best Specific Social Security Regime manager in Brazil, with proven excellence, with the following directives:
1) Satisfaction in rendering services to its clientele;
2) Good asset and liability management practices;
