Corning Inc. recently announced the final results of its previously announced modified Dutch auction tender for its outstanding zero coupon convertible debentures.

Corning has accepted for purchase $834 million aggregate principal amount at maturity of debentures validly tendered and not withdrawn at a purchase price of $747.50 per $1000 of principal amount at maturity.
