Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The Unaudited Pro Forma Condensed Consolidated Statement of Financial Position as of September 30, 2010 has been presented after giving effect to the completion of the Transaction as if it had occurred on September 30, 2010.

The Unaudited Pro Forma Condensed Consolidated Statements of Earnings for the nine months ended September 30, 2010 and 2009 and for the years ended December 31, 2009, 2008, and 2007, have been presented after giving effect to the completion of the Transaction as if it had occurred on January 1, 2007 and do not assume interest income on expected cash proceeds.

The unaudited pro forma condensed consolidated financial statements as of and for the respective periods presented have been derived primarily from the historical audited consolidated financial statements of the Company contained in its Annual Report on Form 10-K for the year ended December 31, 2009 as well as the unaudited consolidated financial statements of the Company contained in its quarterly report on Form 10-Q for the quarter ended September 30, 2010. The unaudited pro forma condensed consolidated financial statements are based upon available information and assumptions that the Company believes are reasonable under the circumstances and were prepared to illustrate the estimated effects of the Transaction, if the Transaction occurred as of and on the dates specified above. As the Transaction has not been completed, the Company has not finalized its accounting for discontinued operations for the periods presented herein, and therefore amounts reported in future financial statements with the Securities and Exchange Commission for the periods presented herein could differ from these pro forma estimates.

The unaudited pro forma condensed consolidated financial statements have been provided for informational purposes and should not be considered indicative of the financial condition or results of operations that would have been achieved had the Transaction occurred as of or for the periods presented. In addition, the unaudited pro forma condensed consolidated financial statements do not purport to indicate financial position or results of operations as of any future date or for any future period, including expected benefits and incremental earnings that may arise, if any, from the Transaction. The unaudited pro forma financial statements, including the related notes, should be read in conjunction with the historical audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009 and the historical unaudited condensed consolidated financial statements included in the Company’s quarterly report on Form 10-Q for the quarter ended September 30, 2010.

The PET business, assets, and technology to be sold by the Company in the Transaction are substantially all of the Performance Polymers segment. Performance Polymers segment operating results will be presented as discontinued operations in the Company’s future filings with the SEC. Corporate costs which were allocated to the Performance Polymers segment will be reallocated to other segments in the Company’s financial statements.
