Senior Indebtedness will not include trade accounts payable, accrued liabilities arising in the ordinary course of business or indebtedness to our subsidiaries. Senior Indebtedness will be entitled to the benefits of the subordination provisions in the subordinated indenture irrespective of the amendment, modification or waiver of any term of the Senior Indebtedness. We may not amend the subordinated indenture to change the subordination of any outstanding Senior Indebtedness without the consent of each holder of Senior Indebtedness that the amendment would adversely affect. The subordinated indenture does not limit the amount of Senior Indebtedness that we may issue. Concerning the Indenture Trustee The Bank of New York Mellon Trust Company, N.A., and certain of its affiliates act as trustees for our first and refunding mortgage bonds and certain pollution control bonds issued on our behalf. The Bank of New York Mellon Trust Company, N.A., also is the trustee under an indenture under which our parent, Edison International, may issue debt securities in the future. We maintain bank deposits with The Bank of New York Mellon and may borrow money from the bank from time to time. Gover
