Ala. Code § 9-14A-13
The proceeds derived from the sale of each series of the bonds issued pursuant to this chapter by the Alabama State Parks System Improvement Corporation other than refunding bonds shall be paid into the State Treasury upon receipt thereof, and the State Treasurer shall keep such proceeds, as well as all income received from the investment and reinvestment of such proceeds (including income derived from the investment and reinvestment of previously derived income), in a special fund in the State Treasury, designated "The Alabama State Parks System Improvement Fund," pending the expenditure of such proceeds and income for the purposes hereinafter authorized and as required by said amendment. All proceeds so deposited in the State Treasury shall be continuously invested by the State Treasurer in permitted investments, and as and when income from the investment of such proceeds is received, such income shall be kept continuously invested in the same manner as such proceeds. The State Treasurer, on the advice of the officers of the corporation, acting on projections of expenditures provided by the Director of Finance, shall keep all such proceeds, together with the income derived from the investment and reinvestment thereof, invested in investments which shall mature or otherwise be subject to liquidation on such terms as will provide cash when required for the purposes for which bonds may be issued pursuant to this chapter.
