After the effective date of suspension of the operation of this chapter, the operations of the commission shall be concluded and any and all moneys remaining held by the commission, collected by assessments and not required to defray the expenses of concluding 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 the pro rata refund to these persons, any such moneys remaining and any moneys remaining after payment of all expenses of winding up and terminating operations shall be withdrawn from the approved depository and paid into the University of California for continued research on cherries.
