Except as provided in paragraphs (2) and (4), any amounts allocated to a metropolitan city or an urban county pursuant to the preceding provisions of this section which are not received by the city or county for a fiscal year because of failure to meet the requirements of subsection (a), (b), (c), or (d) of section 5304 of this title , or which become available as a result of actions under section 5304(e) or 5311 of this title, shall be reallocated in the succeeding fiscal year to the other metropolitan cities and urban counties in the same metropolitan area which certify to the satisfaction of the Secretary that they would be adversely affected by the loss of such amounts from the metropolitan area. The amount of the share of funds reallocated under this paragraph for any metropolitan city or urban county shall bear the same ratio to the total of such reallocated funds in the metropolitan area as the amount of funds awarded to the city or county for the fiscal year in which the reallocated funds become available bears to the total amount of funds awarded to all metropolitan cities and urban counties in the same metropolitan area for that fiscal year, except that—
(A) in determining the amounts awarded to cities or counties for purposes of calculating shares pursuant to this sentence, there shall be excluded from the award of any city or county any amounts which become available as a result of actions against such city or county under section 5311 of this title ;
(B) in reallocating amounts resulting from an action under section 5304(e) of this title or section 5311 of this title , a city or county against whom any such action was taken in a fiscal year shall be excluded from a calculation of share for purposes of reallocating, in the succeeding year, the amounts becoming available as a result of such action; and
(C) in no event may the share of reallocated funds for any metropolitan city or urban county exceed 25 per centum of the amount awarded to the city or county under subsection (b) for the fiscal year in which the reallocated funds under this paragraph become available.
Any amounts allocated under subsection (b) which become available for reallocation and for which no metropolitan city or urban county qualifies under this paragraph shall be added to amounts available for allocation under such subsection (b) in the succeeding fiscal year.
