D. Each participating employer shall make annual contributions to the Fund and provide information as determined by VRS. The amount of the contribution for each participating employer shall be determined on a current disbursement basis in accordance with the provisions of this section. For purposes of establishing contribution amounts for participating employers, a member of any fire company or department or rescue squad that has been recognized by an ordinance or a resolution of the governing body of any locality of the Commonwealth as an integral part of the official safety program of such locality shall be considered part of the locality served by the company, department, or rescue squad. If a company, department, or rescue squad serves more than one locality, the affected localities shall determine the basis and apportionment of the required covered payroll and contributions for each company, department, or rescue squad. If any participating employer fails to remit contributions or other fees or costs associated with the Fund, VRS shall inform the State Comptroller and the affected participating employer of the delinquent amount. In calculating the delinquent amount, VRS may impose an interest rate of one percent per month of delinquency. The State Comptroller shall forthwith transfer such delinquent amount, plus interest, from any moneys otherwise distributable to such participating employer.
