(A) The normal cost, determined as a level percentage of covered annual payroll;
(B) The unfunded accrued liability payment; which, for the purposes of this section, means the level amount or the level percentage of covered annual payroll that, when contributed annually to the Fund for a period of not greater than 30 years, would be sufficient to fund the liability for benefits accrued by participants as of the valuation date (“accrued liability”) in excess of the current value of assets of the Fund (“unfunded accrued liability”);

(3)(A) On the basis of the most recent determinations made under paragraph (1) of this subsection, the enrolled actuary shall certify to the Chief Financial Officer each year, at a time specified by the Chief Financial Officer, the following information for the next fiscal year with respect to the Fund:
