[company_age]34.0[/company_age][employees]2-10 employees[/employees][description]FONSEA is a pre-existing pension fund established in 1989 to provide additional pension benefits to its subscribers. It operates in a defined contribution scheme, where the amount of pension benefit is determined by the contributions made and their yields. FONSEA was formed through an agreement between SEA Airport and regional unions' secretariats to provide social security and social interventions to SEA staff. The initiative was later extended to other airports. In 1996, FONSEA was separated from the outreach activities (health care) managed by the Health Fund, in accordance with the rules laid down in Leg. Dec. No. 124/1993. FONSEA is registered with the pension supervisory authority COVIP under No. 1126.[/description][ps]Pension fund[/ps]
