42 U.S. Code § 15042 - Allotments and payments
To assist States in meeting the requirements of section 15043(a) of this title, the Secretary shall allot to the States the amounts appropriated under section 15045 of this title and not reserved under paragraph (6). Allotments and reallotments of such sums shall be made on the same basis as the allotments and reallotments are made under subsections (a)(1)(A) and (e) of section 15022 of this title, except as provided in paragraph (2).
Notwithstanding paragraphs (1) and (2), if the aggregate of the amounts to be allotted to the States pursuant to such paragraphs for any fiscal year exceeds the total amount appropriated for such allotments under section 15045 of this title for such fiscal year, the amount to be allotted to each State for such fiscal year shall be proportionately reduced.
In a State in which the system is housed in a State agency, the State may use not more than 5 percent of any allotment under this subsection for the costs of monitoring the administration of the system required under section 15043(a) of this title.
Notwithstanding any other provision of law, the Secretary shall pay directly to any system in a State that complies with the provisions of this part the amount of the allotment made for the State under this section, unless the system specifies otherwise.
Any amount paid to a system under this part for a fiscal year and remaining unobligated at the end of such year shall remain available to such system for the next fiscal year, for the purposes for which such amount was paid.
