The disability benefit shall be paid in monthly installments. The disability benefit of a generational member shall terminate upon attaining normal retirement age, or if the member commences a disability benefit within five years of normal retirement age, after receiving the disability benefit for five years, and thereafter the member shall receive a retirement benefit. In order to start the retirement benefit, the member shall submit a completed retirement application that includes the benefit option elected by the member. The single life benefit is equal to the amount the member received as a disability benefit.
