9 and may be supplemented or amended from time to time. The senior indenture and the subordinated indenture are substantially similar but differ in some important respects. The material differences between the senior indenture and the subordinated indenture are set forth in the description below under “Description of the Debt Securities.” DESCRIPTION OF THE FIRST MORTGAGE BONDS The following description discusses the general terms and provisions of the first and refunding mortgage bonds that we may offer by this prospectus in one or more distinct offerings. In this prospectus, we refer to the first and refunding mortgage bonds as “first mortgage bonds” or “bonds.” The first mortgage bonds will be an additional series of our secured debt securities created by resolution of our board of directors or the executive committee of the board, or by an action of one or more of our authorized officers, and will be issued under the first mortgage bond indenture, as amended and supplemented by supplemental indentures. The first mortgage bond indenture gives us broad authority to set the particular terms of each series of first mortgage bonds, including the right to modify certain of the terms contained in the first mortgage bond indenture. The particular terms of a series of bonds and the extent, if any, to which the particular terms of the issue modify the terms of the first mortgage bond indenture will be described in the prospectus supplement relating to the bonds.
