If monies withheld or required to be withheld pursuant to any stop notice or bonded stop notice are insufficient to pay in full the valid claims of all persons who made claims, the monies withheld or required to be withheld shall be distributed among those persons in the same ratio that their respective claims bear to the aggregate of all such valid claims. This pro rata distribution shall be made among the persons entitled to a share without regard to the order of time in which their respective notices were given or their respective actions, if any, were filed.
