Assessments collected from the Federal Home Loan Banks shall not exceed the amounts sufficient to provide for the costs and expenses described in subsection (a) relating to the Federal Home Loan Banks.
The annual assessment shall be payable semiannually for each fiscal year, on October 1 and April 1.
The Director may adjust the amounts of any semiannual payments for an assessment under subsection (a) that are to be paid pursuant to subsection (b) by a regulated entity, as necessary in the discretion of the Director, to ensure that the costs of enforcement activities under this Act for a regulated entity are borne only by such regulated entity.
If at any time, as a result of increased costs of regulation of a regulated entity that is not classified (for purposes of subchapter II) as adequately capitalized or as the result of supervisory or enforcement activities under this Act for a regulated entity, the amount available from any semiannual payment made by such regulated entity pursuant to subsection (b) is insufficient to cover the costs of the Agency with respect to such entity, the Director may make and collect from such regulated entity an immediate assessment to cover the amount of such deficiency for the semiannual period. If, at the end of any semiannual period during which such an assessment is made, any amount remains from such assessment, such remaining amount shall be deducted from the assessment for such regulated entity for the following semiannual period.
Except with respect to amounts collected pursuant to subsection (a)(3), if any amount from any annual assessment collected from an enterprise remains unobligated at the end of the year for which the assessment was collected, such amount shall be credited to the assessment to be collected from the enterprise for the following year.
At the end of each year for which an assessment under this section is made, the Director shall remit to each regulated entity any amount of assessment collected from such regulated entity that is attributable to subsection (a)(3) and is in excess of the amount the Director deems necessary to maintain a working capital fund.
Notwithstanding any other provision of law, any amounts remaining in the Federal Housing Enterprises Oversight Fund established under this section (as in effect before the effective date of the Federal Housing Finance Regulatory Reform Act of 2008, and any amounts remaining from assessments on the Federal Home Loan Banks pursuant to section 1438(b)  of this title), shall, upon such effective date, be treated for purposes of this subsection as amounts received from assessments under this section.
Pursuant to a request under subparagraph (A), the Secretary of the Treasury shall invest such amounts in Government obligations guaranteed as to principal and interest by the United States with maturities suitable to the needs of the Agency and bearing interest at a rate determined by the Secretary of the Treasury taking into consideration current market yields on outstanding marketable obligations of the United States of comparable maturity.
