There shall at all times be one or more trustees under every indenture qualified or to be qualified pursuant to this subchapter, at least one of whom shall at all times be a corporation organized and doing business under the laws of the United States or of any State or Territory or of the District of Columbia or a corporation or other person permitted to act as trustee by the Commission (referred to in this subchapter as the institutional trustee), which (A) is authorized under such laws to exercise corporate trust powers, and (B) is subject to supervision or examination by Federal, State, Territorial, or District of Columbia authority. The Commission may, pursuant to such rules and regulations as it may prescribe, or by order on application, permit a corporation or other person organized and doing business under the laws of a foreign government to act as sole trustee under an indenture qualified or to be qualified pursuant to this subchapter, if such corporation or other person (i) is authorized under such laws to exercise corporate trust powers, and (ii) is subject to supervision or examination by authority of such foreign government or a political subdivision thereof substantially equivalent to supervision or examination applicable to United States institutional trustees. In prescribing such rules and regulations or making such order, the Commission shall consider whether under such laws, a United States institutional trustee is eligible to act as sole trustee under an indenture relating to securities sold within the jurisdiction of such foreign government.

Such institution ^[1] trustee shall have at all times a combined capital and surplus of a specified minimum amount, which shall not be less than $150,000. If such institutional trustee publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, the indenture may provide that, for the purposes of this paragraph, the combined capital and surplus of such trustee shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

If the indenture to be qualified requires or permits the appointment of one or more co-trustees in addition to such institutional trustee, the rights, powers, duties, and obligations conferred or imposed upon the trustees or any of them shall be conferred or imposed upon and exercised or performed by such institutional trustee, or such institutional trustee and such co-trustees jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed, such institutional trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties, and obligations shall be exercised and performed by such co-trustees.

In the case of certificates of interest or participation, the indenture trustee or trustees shall have the legal power to exercise all of the rights, powers, and privileges of a holder of the security or securities in which such certificates evidence an interest or participation.

No obligor upon the indenture securities or person directly or indirectly controlling, controlled by, or under common control with such obligor shall serve as trustee upon such indenture securities.
