Old-age and survivors' insurance (OASI)
Old-age and survivors' insurance (OASI) is the cornerstone of the Swiss social insurance system. It grants pensions of two basic types: old age pensions to people of retirement age, and so called survivors' pensions to spouses or dependent children of a deceased insured person. Old-age pensions should enable their beneficiaries to retire with a considerable measure of financial autonomy. Survivors' pensions aim to ensure that families already burdened by the death of a close family member are spared financial hardship.
