| • | provisions for electronic issuance of debt securities or for debt securities in uncertificated form; and |

Debt securities of any series may be issued as registered debt securities, bearer debt securities, or uncertificated debt securities, and in such denominations as specified in the terms of the series.
In connection with its original issuance, no bearer security will be offered, sold or delivered to any location in the United States, and a bearer security may be delivered in connection with its original issuance only upon presentation of a certificate in a form prescribed by us to comply with United States laws and regulations.
Securities may be issued under the indenture as discounted debt securities to be offered and sold at a discount from the principal amount thereof. Special United States federal income tax and other considerations applicable thereto will be described in the prospectus supplement relating to such discounted debt securities. “Discounted debt security” means a security where the amount of principal due upon acceleration or redemption is less than the stated principal amount.
We are not obligated to issue all debt securities of one series at the same time and, unless otherwise provided in the prospectus supplement, we may reopen a series, without the consent of the holders of the debt securities of that series, for the issuance of additional debt securities of that series. Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of such series, except for the date of original issuance, the date and amount of the first interest payment, the offering price and any other changes required by law and will have the same CUSIP number unless not fungible with the previously-issued debt securities of such series for federal income tax purposes, and will be consolidated with, and form a single series with, such outstanding debt securities.
Ranking
The debt securities will be unsecured and will rank equally with all of our existing and future unsecured senior debt, which includes indebtedness under our pollution control bonds which totaled approximately $204,498,000 as of June 30, 2017, our 3.3% Senior Notes due December 15, 2022, our 6% Senior Notes due May 15, 2035, our 7.5% Senior Notes due March 15, 2038 and our 5.0% Senior Notes due December 1, 2044, which totaled $1,173,767,000 as of June 30, 2017 (fair value based on estimated market prices for similar issues), and our Rio Grande Resources Trust (“RGRT”) 4.47% Senior Notes, Series B, due August 15, 2017 and 5.04% Senior Notes, Series C, due August 15, 2020 (collectively, the “RGRT Notes”), which totaled $98,075,000 as of June 30, 2017. RGRT is a Texas grantor trust through which we finance a portion of our nuclear fuel for Palo Verde. We guarantee the payment of principal and interest on the RGRT Notes. The debt securities will be senior to any existing and future indebtedness which by its terms is made subordinate to the debt securities.
The debt securities will also rank equally with our $350,000,000 unsecured revolving credit facility (“RCF”). We have the ability to increase the RCF by up to $50 million (up to a total of $400 million) upon the satisfaction of certain conditions, including obtaining commitments from lenders or third party financial institutions. The RCF has a term ending January 2020. We may extend the maturity date for one additional year to January 2021, upon the satisfaction of certain conditions. As of June 30, 2017, we and RGRT had borrowed approximately $178,884,000 under this facility.
The debt securities are unsecured obligations. Our secured debt is effectively senior to the debt securities to the extent of the value of the assets securing such secured debt. As of June 30, 2017, we had no secured debt outstanding.
Certain Covenants
The indenture contains several customary covenants, including covenants relating to payment of principal and interest, our continued corporate existence and the filing of reports with the SEC and the trustee.
