(b) The comptroller shall provide to each participating institution a notice of the amount of the assessment against the institution.
(c) A participating institution shall remit to the comptroller the amount assessed against it under this section not later than the 45th day after the date the institution receives the notice under Subsection (b).
(d) Money remitted to the comptroller under this section may be appropriated only for the purposes of administering this subchapter.
