Okla. Stat. tit. 36, § 36-2917: Contributions to insurer

The attorney or other parties may advance to a domestic

reciprocal insurer upon reasonable terms such funds as it may

require from time to time in its operations. Sums so advanced shall

not be treated as a liability of the insurer, and, except upon

liquidation of the insurer, shall not be withdrawn or repaid except

out of the insurer's realized earned surplus in excess of its

minimum required surplus. No such withdrawal or repayment shall be

made without the advance approval of the Insurance Commissioner.
