with the closure of our graphite electrode manufacturing operations at Caserta, Italy, a $0.5 million charge primarily associated with the relocation of our corporate headquarters from Wilmington, Delaware to Parma, Ohio, an $0.8 million charge associated with the phase out of our graphite electrode machining operations in Clarksville, Tennessee and a $0.4 million charge associated with the closure of our advanced graphite machining operations in Sheffield, United Kingdom, offset by a $1.3 million benefit associated with a change in estimate pertaining to the closure of certain graphite electrode manufacturing operations. For 2005, includes a $2.9 million charge related to the impairment of our long-lived carbon electrode fixed assets in Columbia, Tennessee.

Provision for income taxes in 2005 was a charge of $150.2 million primarily due to a charge resulting from a net change in the total valuation allowance for 2005 of $137.9 million. During the 2005 year end financial accounting closing process, we determined that the timing of when we will generate sufficient U.S. taxable income to realize our U.S. deferred tax assets became less certain; therefore, we recorded valuation allowances.

For 2006, includes a restructuring charge of $10.0 million, pertaining primarily to charges associated with the rationalization of our graphite electrode facilities, including those in France and the United States, a $1.8 million charge associated with the closure of our graphite electrodes manufacturing operations in Caserta, Italy, a $1.4 million charge primarily associated with the relocation of our corporate headquarters from Wilmington, Delaware to Parma, Ohio and a $2.7 million charge associated with severance and other costs related to the shutdown of our carbon electrode production operations in Columbia, Tennessee.

For 2006, includes a $6.6 million impairment charge related to the abandonment of capitalized costs related to our enterprise resource planning system, caused by indefinite delays in the implementation of remaining facilities, a $1.4 million impairment charge related to the write-down of long-lived assets in our former Etoy, Switzerland facility, as the estimated fair value less selling costs exceeded book value, a $0.8 million loss related to the abandonment of certain long-lived assets associated with the accelerated closing of our carbon electrode facility in Columbia, Tennessee, and a $1.7 million loss for the abandonment of certain fixed assets related to our graphite electrode operations.

For 2007, includes a charge related to our incentive compensation program amounting to $23.5 million.

Quarterly Data:

The following quarterly selected consolidated financial data have been derived from the Consolidated Financial Statements for the periods indicated which have not been audited. The selected quarterly consolidated financial data set forth below should be read in conjunction with “Part I. Preliminary Notes–Presentation of Financial, Market and Legal Data,” “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the Consolidated Financial Statements and Notes thereto.

The 2008 second quarter includes a $4.1 million gain on derecognition of debt for the Debentures and a $9.0 million charge for the make-whole payment made in connection with the derecognition of the Debentures.

3

The 2008 third quarter includes a $2.0 million loss on the extinguishment of Senior Notes.

The 2008 fourth quarter includes a $36.2 million write down, net of our equity in earnings, related to our investment in a non-consolidated affiliate. Also includes a $2.1 million increase to our severance reserve.

The 2007 first quarter includes a $0.9 million restructuring charge, primarily pertaining to severance and related costs associated with our former Etoy, Switzerland and Clarksville, Tennessee facilities and a $7.5 million loss on extinguishment of the Senior Notes.

The 2007 second quarter includes a $2.8 million loss on extinguishment of Senior Notes, and a $23.7 million gain from the sale of our Caserta, Italy facility.

The 2007 third quarter includes a $2.8 million loss on the extinguishment of Senior Notes, and a $1.3 million gain on the sale of our Vyazma, Russia facility.

The 2007 fourth quarter includes a $0.6 million restructuring charge, primarily related to changes in estimates of the timing and amounts of severance and related costs to certain employees in Caserta, Italy, and a $4.7 million charge for the settlement of our South Africa pension obligations.

The results for the fourth quarter of 2007 include an adjustment to income tax expense related to an invalid “check the box” tax election that was made in 2004 for our Swiss entity. The invalid “check the box” tax election resulted in an understatement of 2005 income tax expense of $7.2 million and overstatement of fourth quarter 2006 income tax expense of $1.3 million. We corrected this error in the fourth quarter of 2007, which resulted in an overstatement of fourth quarter income tax expense of $1.5 million.

In the fourth quarter of 2006, the gain from the sale of our former cathodes business reported in discontinued operations should have been $2.3 million higher ($0.7 million net of tax) than the actual reported gain, as the amount was incorrectly recorded to the cumulative translation adjustment account in equity in 2006. This error was corrected in the fourth quarter of 2007. This resulted in an understatement of net income of $0.7 million in the fourth quarter of 2006 and a corresponding overstatement of net income in the fourth quarter of 2007.

We have determined that the impact of these items was not material to any of the quarterly or annual periods affected.
