After the effective date of suspension of this chapter and of the commission, the operations of the commission shall be wound up, and any asset of the commission shall be liquidated and the proceeds, along with any and all moneys remaining held by the commission, collected by assessment and not required to defray the expenses of winding up and terminating operations of the commission, shall be returned upon a pro rata basis to all persons from whom assessments were collected in the immediately preceding current 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to those persons, any moneys remaining after payment of all expenses of winding up and terminating operations shall be withdrawn from the approved depository and paid to any existing state or federally authorized avocado program. If no program exists, the moneys shall be paid into the State Treasury as unclaimed trust moneys.
