ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

On February 12, 2007, the registrant released the results of operations and financial condition for the three and twelve months ended December 31, 2006. Attached as Exhibit 99, and incorporated herein by reference, is a copy of the registrant's earnings press release dated February 12, 2007.

Included in Exhibit 99 are references to the Company's income (loss) and earnings (loss) per share from continuing operations before cumulative effect of accounting change, which in some cases as noted in such Exhibit, exclude the effects of the impairment and other (gains) and losses recorded during the applicable periods of 2005 and 2006 and additionally in the case of 2006, a charge for the early termination of a supply contract. The Company believes that these non-GAAP financial measures provide comparative information to the original earnings guidance that was provided by the Company throughout the year and therefore is useful to the investment community. Reconciliations of these non-GAAP financial measures to what the Company believes is the most directly comparable U.S. GAAP financial measures are provided in such Exhibit. In addition, guidance for 2007 earnings per share from continuing operations excludes an estimated non-recurring gain. The Company believes this presentation provides guidance for comparison with historical performance.
