The Commission may, after consultation with and taking into consideration the views of the Federal banking agencies (as defined in section 1813 of title 12), adopt rules and regulations, and issue orders, consistent with the protection of investors, prescribing the conditions under which a bank, or an affiliated person of a bank, either of which is an affiliated person of a principal underwriter for, or depositor of, a registered unit investment trust, may serve as trustee or custodian under subsection (a)(1).
It shall be unlawful for any depositor or trustee of a registered unit investment trust holding the security of a single issuer to substitute another security for such security unless the Commission shall have approved such substitution. The Commission shall issue an order approving such substitution if the evidence establishes that it is consistent with the protection of investors and the purposes fairly intended by the policy and provisions of this subchapter.
In the event that a trust indenture, agreement of custodianship, or other instrument pursuant to which securities of a registered unit investment trust are issued does not comply with the requirements of subsection (a), such instrument will be deemed to meet such requirements if a written contract or agreement binding on the parties and embodying such requirements has been executed by the depositor on the one part and the trustee or custodian on the other part, and three copies of such contract or agreement have been filed with the Commission.
Whenever the Commission has reason to believe that a unit investment trust is inactive and that its liquidation is in the interest of the security holders of such trust, the Commission may file a complaint seeking the liquidation of such trust in the district court of the United States in any district wherein any trustee of such trust resides or has its principal place of business. A copy of such complaint shall be served on every trustee of such trust, and notice of the proceeding shall be given such other interested persons in such manner and at such times as the court may direct. If the court determines that such liquidation is in the interest of the security holders of such trust, the court shall order such liquidation and, after payment of necessary expenses, the distribution of the proceeds to the security holders of the trust in such manner and on such terms as may to the court appear equitable.
For purposes of paragraph (2), the fees and charges deducted under the contract shall include all fees and charges imposed for any purpose and in any manner.
The Commission may issue such rules and regulations to carry out paragraph (2)(A) as it determines are necessary or appropriate in the public interest or for the protection of investors.
