Notwithstanding any other law to the contrary and subject to the standard contained in sections 11-50-113 (2) and 15-1-304, C.R.S., a Colorado bank or trust company may invest and reinvest the assets that it maintains in its trust in the securities of any open-end or closed-end management investment company or investment trust registered under the federal "Investment Company Act of 1940", 15 U.S.C. sec. 80a1-64, as amended. A Colorado bank or trust company shall be allowed to make such investment even if it exercises investment discretion as a fiduciary, custodian, managing agent, or otherwise with respect to the investment and reinvestment of assets that it maintains in its trust department. The fact that a Colorado bank or trust company, or any affiliate thereof, is providing services to the investment company or trust as investment advisor, sponsor, distributor, custodian, transfer agent, registrar, or otherwise, and receiving reasonable remuneration for the services, does not preclude such bank or trust company from investing in the securities of such investment company or trust.
