Ohio Revised Code Title XXXIII. Education Libraries § 3307.63

(A) An annuity having a reserve equal to the amount of the member's accumulated contributions at that time;

(B) A pension that shall be the difference between the annuity and an annual amount determined by multiplying the number of years of Ohio service credit of such member, and in addition the number of years and fraction of a year between the effective date of the member's disability retirement and the date the member attained age sixty, assuming continuous service, by two per cent of the member's final average salary. Such disability retirement shall not be less than thirty per cent nor more than seventy-five per cent of the member's final average salary, except that it shall not exceed any limit to which the retirement system is subject under section 415 of the “Internal Revenue Code of 1986,” 100 Stat. 2085, 26 U.S.C.A. 415, as amended.

If the member is not receiving a disability benefit under section 3307.57 of the Revised Code, but is receiving a disability benefit from either the public employees retirement system or the school employees retirement system, then such member shall not be eligible for service credit based upon the number of years and fractions thereof between the date of disability and the date the member attained age sixty as otherwise provided in this section.

A disability retirant under this section whose disability retirement has been terminated, when eligible, may apply for service retirement provided by section 3307.58 of the Revised Code.
