In Switzerland, the term “Old Age and Survivors Insurance” or “OASI” refers to a government-regulated pension scheme run by regional social security offices.
The scheme guarantees a basic old-age pension to its members when they reach legal retirement age. It also guarantees a basic pension to surviving dependents in the event of death.
Membership in this scheme is obligatory for all individuals residing in Switzerland, regardless of whether residents are employed, self-employed or unemployed.
When OASI members are employed, contributions to the scheme are shared evenly between the employee and the employer.
