Ohio Rev. Code Ann. § 145.48 – Rate of employer contribution

(A) Each employer shall pay to the public employees retirement system an amount that shall be a certain per cent of the earnable salary of all contributors to be known as the "employer contribution," except that the public employees retirement board may raise the employer contribution to a rate not to exceed fourteen per cent of the earnable salaries of all contributors.
(B)
1. (1) On the basis of regular interest and of such mortality and other tables as are adopted by the public employees retirement board, the actuary for the board shall determine the liabilities and employer rates of contribution as follows:
  1. (a) The percentage of earnable salary that, when added to the per cent of earnable salary contributed by each member, will cover the costs of benefits to be paid to members for each year of service rendered;
  2. (b) The percentage of earnable salary that, if paid over a period of future years, will discharge fully the system's unfunded actuarial accrued pension liability;
  3. (c) The percentage of earnable salary designated by the board to pay benefits authorized under section 145.58 of the Revised Code.
2. (2) If recognized assets exceed the liabilities for service previously rendered, on approval of the board, a percentage of earnable salary may be deducted from the employer rates of contribution that, if deducted annually over a period of future years, will eliminate the excess.
