Whenever any money has been deposited in trust in the Treasury by any state agency because it has remained unclaimed, or the claimant cannot be found, the Treasurer shall hold it for the claimant for a period of two years and if it is not paid within that period, the amount so deposited shall revert to and become a part of the General Fund, except that the face amount of each unclaimed warrant deposited pursuant to Section 16373 shall revert and be credited by the Controller to the fund against which the warrant was drawn.
