Debt Disclosure [Text Block] | 4. Debt Based on borrowing rates currently available to us for loans with similar terms and maturities, the fair value of long-term debt was $4.3 billion at June 30, 2016 and $4.1 billion at December 31, 2015, compared to recorded book values of $3.9 billion at June 30, 2016 and December 31, 2015. The Company measures the fair value of its long-term debt using Level 2 inputs based primarily on current market yields for its existing debt traded in the secondary market. On July 20, 2016, Corning’s Board of Directors approved a $1 billion increase to our commercial paper program, raising it to $2 billion. If needed, this program is supported by our $2 billion revolving credit facility that expires in 2019. At June 30, 2016, Corning had $252 million in outstanding commercial paper as part of the Company’s commercial paper program established in the second quarter of 2013. The estimated fair value of this commercial paper approximates its carrying value due to the short-term maturities. Debt Issuances 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. We can redeem these debentures at any time, subject to certain stipulations.
