California Code, Business and Professions Code - BPC § 17550.11

(a) “Adequate bond” means a bond executed by an admitted surety insurer in an amount at all times no less than at least equal to the amount required to be held in a trust account pursuant to Section 17550.15 by any seller of travel in conjunction with such transportation, for the benefit of every passenger who sustains a monetary loss as a result of any violation of this article by a seller of travel or any failure by a seller of travel or by any official, agent, or employee of the seller of travel acting in the course or scope of their employment or agency.  A seller of travel filing the bond shall maintain the bond in force in the proper amount as a condition of continuing to engage in business.  The admitted surety insurer issuing the bond shall provide 30 days' written notice before cancellation or termination of the bond to the seller of travel filing the bond and the office of the Attorney General, Consumer Protection Section.  Cancellation of the bond shall not limit or exonerate the surety insurer from claims against the bond arising during the period it was in force.

(b) No passenger may recover upon the bond a sum greater than that which the passenger paid to the seller of travel, provided that this limitation shall not restrict a passenger from recovering sums greater than those paid to the seller of travel from sources other than the bond.
