HOUSTON, Dec. 28 /PRNewswire-FirstCall/ -- Colorado Interstate Gas Company (CIG), a majority owned subsidiary of El Paso Corporation (NYSE:EP), announced the expiration and final results of its previously announced cash tender offer to purchase up to $125 million aggregate principal amount of its 5.95-percent Senior Notes due March 15, 2015 (CUSIP No. 196522AH9). The tender offer expired at 12:00 midnight, Eastern Time, on December 27, 2007. $183,525,000 in aggregate principal amount of notes were validly tendered in the tender offer. Because this amount exceeded the tender cap of $125 million, the amount of notes accepted for purchase was prorated among tendering holders in accordance with the terms of the Offer to Purchase dated November 29, 2007. The proration factor applied was approximately 68.1-percent (rounded down to the nearest $1,000 of principal amount for each tendering holder). CIG expects settlement of the tender offer to occur today. Merrill Lynch & Co. and J.P. Morgan Securities Inc. served as the dealer managers for the tender offer and Global Bondholders Services Corporation served as the depositary and information agent for the tender offer.
