The increased amount is payable for the ensuing twelve-month period or until the next increase is granted under this section, whichever is later. Subsequent increases shall be determined from the date of the first increase paid to the former member in the case of an allowance being paid a beneficiary under an option, or from the date of the first increase to the survivor first receiving an allowance or benefit in the case of an allowance or benefit being paid to the subsequent survivors of the former member.
The date of the first increase under this section becomes the anniversary date for any future increases.
If payment of a portion of a benefit is made to one or more beneficiaries under "plan F" under division (B)(3)(e) of section 3309.46 of the Revised Code, each increase under this section granted while the plan of payment is in effect shall be divided among the designated beneficiaries in accordance with the portion each beneficiary has been allocated.
