Such activities may include subdividing and developing real property and building residential housing or commercial improvements on such property and may also include owning, renting, leasing, managing, operating for income, or selling such property. Investments in real estate subject to section 11-105-401 may, at the bank's option, be included in investments authorized in this subsection (9) and thereby be removed from the restrictions of section 11-105-401.

A state bank that intends to initiate a program of investments under the authority of this subsection (9) shall give sixty days' advance notice to the division of such intent; except that such notice may be waived in the banking board's discretion where such notice is impracticable or unnecessary. The state bank shall also notify the division within ten days after the commencement of the investment program. If similar notices are required by the bank's federal supervisory agency, the same form of notice may be used for purposes of notice under this subsection (9).

(10) A state bank may invest in the securities of, or other interests in, any open-end and closed-end management type investment company or investment trust registered under the federal "Investment Company Act of 1940", 15 U.S.C. section 80(a)-1 et seq., if the portfolio of such investment company or investment trust is limited to United States government obligations thatare backed by the full faith and credit of the United States government and to repurchase agreements fully collateralized by such obligations and if any such investment company or investment trust actually takes delivery of such collateral, either directly or through an authorized custodian.
