Section 21172 Of Article 6. Disability Retirement From California Government Code >> Division 5. >> Title 2. >> Part 3. >> Chapter 12. >> Article 6.

. If the retirement allowance of any person retired for disability is canceled for any cause other than reentrance into state service, and if he or she does not reenter state service, an amount that is the actuarial equivalent of his or her annuity at cancellation, based on a disabled life, but not exceeding the amount of his or her accumulated contributions at the time of his or her retirement for disability, shall be credited to his or her individual account, and shall be refunded to him or her unless he or she elects, under Section 20731, to allow his or her accumulated contributions to remain in the retirement fund. The actuarial equivalent under this section shall be adjusted by the board every 10 years, or more frequently, to agree with the interest rate and mortality tables in effect at the commencement of each such 10-year or succeeding interval.
