4.	LONG-TERM DEBT

Senior notes issuance - In January 2014, we completed a private placement of senior notes, consisting of $300 million of 2.07 percent senior notes due 2019, $300 million of 3.61 percent senior notes due 2024 and $600 million of 4.658 percent senior notes due 2044 (collectively, our “Senior Notes”). The net proceeds from the private placement were approximately $1.19 billion and were used to fund a one-time cash payment to ONEOK of approximately $1.13 billion as part of the separation. The remaining portion of the net proceeds was retained in order to provide sufficient financial flexibility and to support working capital requirements and capital expenditures.

In connection with the issuance of our Senior Notes, we entered into a registration rights agreement, pursuant to which we were obligated to use our commercially reasonable efforts to file with the SEC and cause to become effective a registration statement with respect to an offer to exchange each series of Senior Notes for new notes, with terms substantially identical in all material respects to such series of our Senior Notes. Our registration statement, as amended, was declared effective by the SEC on September 5, 2014. We completed the noncash exchange of our Senior Notes for our registered senior notes in October 2014.

The indenture governing our Senior Notes includes an event of default upon the acceleration of other indebtedness of $100 million or more. Such events of default would entitle the trustee or the holders of 25 percent in the aggregate principal amount of the outstanding Senior Notes to declare those senior notes immediately due and payable in full.

We may redeem our Senior Notes at par, plus accrued and unpaid interest to the redemption date, starting one month, three months, and six months, respectively, before their maturity dates. Prior to these dates, we may redeem these Senior Notes, in whole or in part, at a redemption price equal to the principal amount, plus accrued and unpaid interest and a make-whole premium. The redemption price will never be less than 100 percent of the principal amount of the respective note plus accrued and unpaid interest to the redemption date. Our Senior Notes are senior unsecured obligations, ranking equally in right of payment with all of our existing and future unsecured senior indebtedness.
