Debt Issuances and Retirements

2015

In the second quarter of 2015, we issued $375 million of 1.50% senior unsecured notes that mature on May 8, 2018 and $375 million of 2.90% senior unsecured notes that mature on May 15, 2022. The net proceeds of $745 million will be used for general corporate purposes. We can redeem these notes at any time, subject to certain customary terms and conditions.

2014

In the third quarter of 2014, we amended and restated our existing revolving credit facility. The amended facility provides a $2 billion unsecured multi-currency line of credit and expires on September 30, 2019. At December 31, 2015, there were no outstanding amounts on this credit facility. The facility includes affirmative and negative covenants that Corning must comply with, including a leverage (debt to capital ratio) financial covenant. As of December 31, 2015, we were in compliance with all of the covenants.

2013

In the first quarter of 2013, we amended and restated our then-existing revolving credit facility. The 2013 amended facility provided a $1 billion unsecured multi-currency line of credit that would have expired in March 2018. This facility was amended and restated by the $2 billion facility entered into in the third quarter of 2014.

In the first quarter of 2013, Corning repaid the aggregate principal amount and accrued interest outstanding on the credit facility entered into in the second quarter of 2011 that allowed Corning to borrow up to Chinese renminbi (RMB) 4 billion. The total amount repaid was approximately $500 million. Upon repayment, this facility was terminated.

In the second quarter of 2013, the Company established a commercial paper program on a private placement basis, pursuant to which we may issue short-term, unsecured commercial paper notes up to a maximum aggregate principal amount outstanding at any time of $1 billion. Under this program, the Company may issue the notes from time to time and will use the proceeds for general corporate purposes. The maturities of the notes will vary, but may not exceed 390 days from the date of issue. The interest rates will vary based on market conditions and the ratings assigned to the notes by credit rating agencies at the time of issuance. The Company’s revolving credit facility is available to support obligations under the commercial paper program, if needed.
