After the effective date of suspension of the operation of this chapter and of the commission, the operations of the commission shall be concluded and any and all remaining funds held by the commission, collected by assessment and not required to defray the expenses of concluding and terminating the operations of the commission, shall be returned upon a pro rata basis to all persons from whom assessments were collected in the immediately preceding marketing season.
However, if the commission finds that the amounts so returnable are so small as to make impractical the computation and remitting of a pro rata refund to these persons, any such funds remaining and any funds remaining after payment of all expenses of winding up and terminating operations shall be withdrawn from the approved depository and paid into an appropriate state authorized navel orange or citrus program. If no such program exists, the funds shall be paid into a federally authorized navel orange or citrus program. If no such program exists, the funds shall be paid into the State Treasury as unclaimed trust money.
