Upon termination of the retirement allowance that began to accrue prior to July 1, 1972, the member's individual account shall be credited with amounts that are the actuarial equivalents at that time, as based on the disabled life, where retirement had been for disability, or on the active life where the retirement had been for service of the allowance and annuities being paid from accumulated retirement contributions, accumulated annuity deposit contributions, or accumulated tax-sheltered annuity contributions.  These credited amounts shall not exceed the amount of his or her accumulated contributions as they were in those accounts at the date of retirement.
