[1] | The goodwill recognized is partially deductible for U.S. income tax purposes. The goodwill was allocated to the Optical Communications and All Other reporting segment in the amount of $213 million and $87 million, respectively.
[2] | As Corning was a 57.5% shareholder at the date of acquisition, immediately preceding the acquisition of Samsung Corning Precision Materials, Corning recognized an asset and respective gain as part of the calculation of its previously held equity investment which included approximately $184 million attributed to its economic interest in the royalty contract.
[3] | In conjunction with the Framework Agreement, the parties agreed to have Samsung Corning Precision Materials distribute all cash and cash equivalents as a dividend to the shareholders of record as of December 31, 2013. The dividend was not part of the purchase price as the agreement was to distribute cash and cash equivalents as a dividend to the shareholders as soon as practicable. As such, at acquisition Corning did not have legal title to the cash to be distributed, although the dividend was distributed subsequent to the acquisition date. Therefore, the portion of Corning's share of the $1.6 billion dividend received was accounted for in Corning's consolidated financial statements as if the dividend occurred at or immediately prior to the date of acquisition at which time Samsung Corning Precision Materials was still an equity method investment in Corning's consolidated financial statements.
