Such premium shall be prorated to July first next, or such other date fixed by the retirement board as is appropriate, and shall be paid to the retirement system in equal installments over the period of the loan. Thereafter, a premium not to exceed one percent per annum of the present value of the outstanding loan as of July first, or such other appropriate date, shall be paid in the same manner each succeeding year until such loan is repaid or the member is retired.
The retirement board shall, at least annually, review such premium rate, and may, in its discretion, increase or reduce the premium, modify the terms or conditions of coverage, or discontinue the insurance of loans. In no event shall this subdivision impose any obligation upon the retirement board to continue to insure loans of members upon the terms and conditions herein provided or upon any other terms or conditions.
