All fees shall be deposited promptly by the proration zone agent in a bank which is approved by the Director of Finance, and shall be accounted for immediately to the Director of Food and Agriculture. Each deposit shall be made in the name of the proration zone under which the funds are collected.
Any money which is so deposited may be invested and reinvested by the Treasurer or marketing program committee in any of the securities which are described in Article 1 (commencing with Section 16430) of Chapter 3 of Part 2 of Division 4 of Title 2 of the Government Code, or placed in a depository as provided in Chapter 4 (commencing with Section 16500) of Part 2 of Division 4 of Title 2 of the Government Code, and handled in the same manner as money in the State Treasury. For these purposes, these moneys may also be combined with funds which are determined by the director to be available for investment pursuant to Section 58939. Any increment which is received from investment, reinvestment, or deposit made by the Treasurer shall be remitted to the marketing program committee. The Treasurer may deduct from the remittance an amount equal to the reasonable cost incurred in carrying out this section or may bill the marketing program committee for the costs, and the marketing program committee shall pay the costs from any money which is collected for it pursuant to this chapter.
