Automatic summary, not yet reviewed
- Surplus revenue that funds contributory Social Security benefits goes on a priority basis to the Reserve Fund. The law explains how that budget surplus is calculated each year.
- The Council of Ministers decides, at least once a year, how much is contributed to the fund and how it is invested. The fund's money can only be used to pay contributory pensions, and only if the system has a deficit, capped at 3% per year and requiring prior approval from the Council of Ministers.
- The fund is invested in securities issued by public legal entities. Three bodies are created: a Management Committee that directs and oversees the fund, an Investment Advisory Commission that advises it, and a Monitoring Commission with union and business representatives that reviews the fund's performance every six months.
- Buying and selling the fund's assets is an off-budget operation, recorded in the budget of the General Treasury of Social Security on the last business day of the year. The Government also submits an annual report on the fund to the Cortes Generales (Spanish Parliament).
Who it affects
- Social Security: Its contributory surpluses feed the fund, which it can only use in deficit situations to pay contributory pensions.
- The Government and the Council of Ministers: They decide each year how much goes into the fund and authorize the use of its assets.
- The Cortes Generales (Spanish Parliament): They receive an annual report on the fund's performance and composition.
