Pub. Util. Code, § 50110

With the consent of the board, the general manager may:

(a) Authorize the trust department of any state or national bank in this State, or a trust company authorized to act as such in this State, to receive as his agent deposits of any securities acquired by the district.

(b) Place and maintain for safekeeping as a trust deposit with the trust department of any state or national banks in this State, or a trust company authorized to act as such in this State, any securities owned by the district.

The bank or trust company selected shall have a total paid-in capital of at least one million dollars ($1,000,000). The general manager shall take from the trust department or trust company a receipt for the securities, and neither the general manager nor the district is responsible for the custody and safe return of the securities until they are withdrawn from the trust department or trust company by the general manager. Any trust department or trust company to which securities are delivered, either as agent or depository for the general manager, shall make such disposition of the securities as the general manager directs and is responsible only for strict compliance with written instructions given to it by the general manager. All such securities are at all times subject to the order of the general manager.
