In December 2014, through a series of open market transactions, we repurchased certain of our 4.5% senior notes, 5.95% senior notes and 6.5% senior notes with an aggregate book value of $138 million and recognized a gain of approximately $11 million.

On April 4, 2012, we completed a $1.3 billion long-term debt offering comprised of $750 million of 4.5% senior notes and $550 million of 5.95% senior notes. The net proceeds from this offering were used to repay short-term indebtedness under our commercial paper program and for general corporate purposes.

In 2012, we received sufficient consents to extend the due date for providing our Form 10-Q filings and our 2012 Form 10-K filing to all series of our publicly traded senior notes. We offered a cash payment of $2.50 for each $1,000 in principal amount for those note holders who consented to the extension and we paid approximately $18 million to the holders of our senior notes in connection with this consent solicitation, which was recognized as an increase in interest expense over the remaining terms of the senior notes. We also incurred and expensed in 2012 other costs, including fees and expenses, of $12 million in connection with our debt consent solicitation.
