Gov. Code, § 16475

At the conclusion of each calendar quarter, all interest earned and other increment derived from investments made pursuant to this article, interest earnings from demand accounts, and interest earnings pursuant to Section 20825 shall, on order of the Controller, be deposited in the Surplus Money Investment Fund. The Controller, after deducting an amount equal to the reasonable costs incurred by the Treasurer, the Controller, and the Department of Finance in carrying out this article, shall apportion, quarterly, to the following funds in the Treasury, interest earned or increment derived for the three calendar months ending with those dates:

(a) The General Fund.

(b) Each fund into which are deposited or which contains moneys collected from any tax now or hereafter imposed by the state upon the manufacture, sale, distribution, or use of motor vehicle fuel, for use in motor vehicles upon the public streets and highways.

(c) Each fund into which are deposited or which contains moneys collected from motor vehicle and other vehicle registration license fees or from any other tax or license fee now or hereafter imposed by the state upon vehicles, motor vehicles or the operation thereof, except those taxes and license fees that, by the provisions of Section 7 of Article XIX of the California Constitution, are exempted from the provisions of Section 2 of Article XIX.

(d) Each fund into which are deposited or that contains moneys collected under any law of this state relating to the protection, conservation, propagation, or preservation of fish, game, mollusks, or crustaceans, and fines imposed by any court for the violation of any of those laws.

(e) Each fund into which are deposited or that contains moneys available for construction, repair, replacement, maintenance or operation of public works of the state, including, but not limited to, the facilities of the State Water Resources Development System, as defined in Section 12931 of the Water Code, toll facilities financed, built, or acquired pursuant to the California Toll Bridge Authority Act (Chapter 1 (commencing with Section 30000) of Division 17 of the Streets and Highways Code), or moneys available for the payment of principal or interest on bonds issued to provide for the construction of those facilities.

(f) Every other fund in respect to which the Director of Finance on the advice of the Attorney General determines that the operation of the California Constitution or the United States Constitution prohibits the expenditure of interest received under this article and allocated on the basis of amounts in that fund for General Fund purposes.

(g) Each fund not included within subdivisions (a) to (f), inclusive.

The apportionments shall be made by the Controller in the following manner:

(1) All money not apportioned to the funds referred to in subdivisions (b), (c), (d), (e), (f), and (g) shall be apportioned to the General Fund.

(2) There shall be apportioned to each of the funds referred to in subdivisions (b), (c), (d), (e), (f), and (g), an amount directly proportionate to the respective amounts transferred from those funds to the Surplus Money Investment Fund and the length of time the amounts remained therein.

(3) Interest accrued or paid to the Pooled Money Investment Account from the proceeds of tax-exempt obligations on loans made pursuant to Section 16312 or 16313, to the extent thereof, shall be deemed apportioned to the State Highway Account or any other accounts that may be designated by the Controller pursuant to Section 16654, but only to the extent of its proportionate earnings as determined under paragraph (2). This paragraph shall neither increase nor decrease the amount of earnings apportioned to any fund or account in accordance with this section. These moneys shall be deemed expended, or applied to reimburse expenditures previously paid, first following the allocation of these interest earnings of the Surplus Money Investment Fund to the State Highway Account or any other accounts that may be designated by the Controller pursuant to Section 16654. It is the intent of the Legislature that this paragraph shall authorize the Treasurer and the Controller to monitor the expenditure of the proceeds of tax-exempt obligations in order to comply with federal tax laws and shall neither increase nor decrease the amount of bonds, notes, or other obligations to be issued by the state or any subdivision thereof, nor shall this paragraph be interpreted to indicate that the allocation is contrary to any bond act.
