Certain benefit options are only available to married participants. Before Retirement, a married participant can choose from a 50%, 75%, or 100% Husband-and-Wife Pension form of payment. If, before retiring, you die before beginning your pension benefit, your surviving spouse may be eligible to receive a survivor benefit (see Survivor Benefits for more details). After Retirement, your pension benefit is not affected if you marry after payments have begun. Once you start receiving pension benefits, you cannot change your form of payment.
