Such formula shall be subject to the review of FHFA, and the OF board of directors shall make any changes to the formula as may be ordered by FHFA from time to time.
(c) Alternative funding method. With the prior approval of FHFA, the OF board of directors may, by contract with a Bank or Banks, choose to be reimbursed through a fee structure, in lieu of or in addition to assessment, for services provided to the Bank or Banks.
(d) Prompt reimbursement. Each Bank from time to time shall promptly forward funds to the OF in an amount representing its share of the reimbursement described in paragraph (b) of this section when directed to do so by the Chief Executive Officer pursuant to the procedures of the OF board of directors.
(e) Indemnification expenses. All expenses incident to indemnification of the members of the OF board of directors, the Chief Executive Officer, and other officers and employees of the OF shall be treated as an expense of the OF to be reimbursed by the Banks under the provisions of this part.
(f) Operating funds segregated. Any funds received by the OF from the Banks pursuant to this section for OF operating expenses promptly shall be deposited into one or more accounts and shall not be commingled with any proceeds from the sale of consolidated obligations in any manner.
