Cal. Government Code § 8880.64

(a) Expenses of the lottery shall include all costs incurred in the operation and administration of the lottery and all costs resulting from any contracts entered into for the purchase or lease of goods and services required by the lottery, including, but not limited to, the costs of supplies, materials, tickets, independent audit services, independent studies, data transmission, advertising, promotion, incentives, public relations, communications, compensation paid to the lottery game retailers, bonding for lottery game retailers, printing, distribution of tickets or shares, reimbursement of costs of services provided to the lottery by other governmental entities, and for the costs of any other goods and services necessary for effectuating the purposes of this chapter. As a promotional expense, the commission may supplement the prize pool of a game or games upon its determination that a supplement will benefit the public purpose of this chapter. (b) (1) Not more than 13 percent of the total annual revenues accruing from the sale of all lottery tickets and shares from all lottery games shall be expended for the payment of the expenses of the lottery.

(c) This section shall become inoperative on April 1 of the year following notification from the Controller to the Legislature and the Governor that the events described in paragraphs (1) and (2) of subdivision (c) of Section 8880.4.5 have occurred, and as of the following January 1 is repealed, unless a later enacted statute, that is enacted before January 1 of that following year, deletes or extends the dates on which it becomes inoperative and is repealed.
