((a)) ** Establishment of campaign fund** There is hereby established on the books of the Treasury of the United States a special fund to be known as the “Presidential Election Campaign Fund”. The Secretary of the Treasury shall, from time to time, transfer to the fund an amount not in excess of the sum of the amounts designated (subsequent to the previous Presidential election) to the fund by individuals under section 6096. There is appropriated to the fund for each fiscal year, out of amounts in the general fund of the Treasury not otherwise appropriated, an amount equal to the amounts so designated during each fiscal year, which shall remain available to the fund without fiscal year limitation.

((b)) ** Payments from the fund** Upon receipt of a certification from the Commission under section 9005 for payment to the eligible candidates of a political party, the Secretary of the Treasury shall pay to such candidates out of the fund the amount certified by the Commission. Amounts paid to any such candidates shall be under the control of such candidates.

((c)) ** Insufficient amounts in fund** If at the time of a certification by the Commission under section 9005 for payment to the eligible candidates of a political party, the Secretary determines that the moneys in the fund are not, or may not be, sufficient to satisfy the full entitlements of the eligible candidates of all political parties, he shall withhold from such payment such amount as he determines to be necessary to assure that the eligible candidates of each political party will receive their pro rata share of their full entitlement. Amounts withheld by reason of the preceding sentence shall be paid when the Secretary determines that there are sufficient moneys in the fund to pay such amounts, or portions thereof, to all eligible candidates from whom amounts have been withheld, but, if there are not sufficient moneys in the fund to satisfy the full entitlement of the eligible candidates of all political parties, the amounts so withheld shall be paid in such manner that the eligible candidates of each political party receive their pro rata share of their full entitlement. In any case in which the Secretary determines that there are insufficient moneys in the fund to make payments under subsection (b), section 9008(i)(2), and section 9037(b), moneys shall not be made available from any other source for the purpose of making such payments.
