In the first variant, the member’s accrued entitlements are maintained when the member is no longer an active member. A member changing jobs can transfer his entitlements to the new pension fund. Also, upon retirement, the member has the right to exchange the survivor’s pension for extra old age pension.
A risk-based survivor’s pension does not have these advantages, and has the nature of an insurance. So long as the member is active and contribution is paid, his survivors will receive a pension benefit should he die. When the member is no longer active, the survivor loses the right to a pension.
In spite of the advantages of an accrual-based survivor’s pension, it has been losing ground for years (see the Chart), because risk-based survivor’s pensions are cheaper and make for lower pension contributions.
