CA Gov't Code Section 17221.5

(a)

The Controller, with the approval of the Pooled Money Investment Board, may fix a maturity date for registered warrants. To the extent legally permissible, the Controller shall pick a date that does not interfere with the payment of bonds, revenue anticipation notes, reimbursement warrants, and refunding warrants.

(b)

Notwithstanding subdivision (a), a registered warrant may be redeemed at the option of the committee prior to the maturity date of the warrant at a redemption price not to exceed the principal amount of the warrant plus the amount of interest, calculated as of the date when the committee calls for the redemption. The Treasurer shall pay the redemption price for the registered warrant from any unapplied money in the General Fund that is available on that redemption date.
