At the completion the Company will have purchased approximately 9 million shares for $650 million since the program was announced on October 9, 2012 using proceeds from the sale of the Coating Resins business.Following completion of the current authorization, the Company has also received approval by its Board of Directors for a new stock buyback authorization of up to $200 million.   David Drillock, Vice President and Chief Financial Officer commented, "We have successfully completed the sale and separation of the Coating Resins business. The new Cytec business portfolio is predominately in growing markets with less demand volatility. It provides Cytec with an overall higher operating margin and we remain an excellent cash flow generator. With the Coatings separation process mostly behind us, mostly stable end markets and our positive outlook for Cytec's future, we feel it is appropriate to reward our shareholders with the remaining excess cash proceeds from the coating resins divestiture."The Company anticipates the new stock buyback authorization to be completed by the end of September 2013.  The extent to which the company repurchases its shares and the timing of such repurchases will depend upon market conditions and other corporate considerations. The repurchases will be made in compliance with, and at such times as permitted by, federal securities law and may be suspended or discontinued at any time.Forward-Looking and Cautionary StatementsExcept for the historical information and discussions contained herein, statements contained in this release may constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.
