Mo. Rev. Stat. § 537.750: Exhaustion of fund, claims to be prorated.

1. If the fund will be exhausted by the payment of all judgments and claims allowed during a particular fiscal year, amounts paid to each claimant or person obtaining a judgment shall be prorated, with each person receiving an amount equal to the percentage his own payment bears to the total of claims and judgments outstanding and payable from the fund. Any amounts due and unpaid as a result of such proration shall be paid in the following fiscal year.

2. If, at the end of any fiscal year, the fund has a balance exceeding projected needs, and adequate reserves, the board may in its discretion refund on a pro rata basis to all participating public entities an amount based on the contributions of the public entity for the immediately preceding year.
