(a) Unless prohibited by will, deed, trust, court order, or other instrument establishing the fiduciary relationship or unless another mode of investment is prescribed by any such instrument, trustees, guardians, and personal representatives, in addition to methods of investment now authorized by law, may invest all funds held in trust or for investment as provided in this chapter.

(b) In addition to other investments authorized by law for the investment of funds held by a fiduciary, or by the instrument governing the fiduciary relationship, and notwithstanding any other provision of law, a bank or trust company acting as a fiduciary, agent, or otherwise may, in the exercise of its investment discretion or at the direction of another person authorized to direct investment of funds held by a bank or trust company as fiduciary, invest and reinvest in the securities of an open-end or closed-end management investment company or investment trust registered under the Investment Company Act of 1940, 15 U.S.C. § 80a-1 et seq., as amended, so long as the portfolio of the investment company or investment trust consists substantially of investments not prohibited by the governing instrument.

(c) The fact that such a bank or trust company or an affiliate of the bank or trust company provides services to the investment company or investment trust such as that of an investment advisor, custodian, transfer agent, registrar, sponsor, distributor, manager, or otherwise and is receiving reasonable compensation for those services shall not preclude the bank or trust company from investing or reinvesting in the securities of the open-end or closed-end management investment trust registered under the Investment Company Act of 1940, 15 U.S.C. § 80a-1 et seq., as amended.
