12 CFR § 160.121 - Investment in state housing corporations.
(a) Any Federal savings association to the extent it has legal authority to do so, may make investments in, commitments to invest in, loans to, or commitments to lend to any state housing corporation; provided, that such obligations or loans are secured directly, or indirectly through a fiduciary, by a first lien on improved real estate which is insured under the National Housing Act, as amended, and that in the event of default, the holder of such obligations or loans has the right directly, or indirectly through a fiduciary, to subject to the satisfaction of such obligations or loans the real estate described in the first lien, or the insurance proceeds.
(b) Any Federal savings association that is adequately capitalized may, to the extent it has legal authority to do so, invest in obligations (including loans) of, or issued by, any state housing corporation incorporated in the state in which such savings association has its home or a branch office; provided (except with respect to loans), that:
(1) The obligations are investment grade; or
(2) The obligations are approved by the OCC. The aggregate outstanding direct investment in obligations under paragraph (b) of this section shall not exceed the amount of the Federal savings association's total capital.
(c) Each state housing corporation in which a savings association invests under the authority of paragraph (b) of this section shall agree, before accepting any such investment (including any loan or loan commitment), to make available at any time to the OCC such information as the OCC may consider to be necessary to ensure that investments are properly made under this section.
