The balance sheet data as of December 31, 2010, 2009 and 2008 and the statements of operations data for the years ended December 31, 2009 and 2008 shown below were derived from previously issued financial statements, adjusted for applicable discontinued operations and the change in accounting policy for defined benefit pension plans and other postretirement benefit plans described below.

Change in accounting policy regarding pension and other postretirement benefits

Effective January 1, 2013, we elected to change our policy for recognizing actuarial gains and losses and changes in the fair value of plan assets for our defined benefit pension plans and other postretirement benefit plans. We now immediately recognize in operating results net actuarial gains and losses and the change in fair value of plan assets annually in the fourth quarter of each fiscal year and whenever a plan is required to be remeasured. The remaining components of our net periodic benefit cost are recorded on a quarterly basis. For further discussion, see Note 2 - Summary of Accounting Policies in the consolidated financial statements included as Exhibit 99.3 to this Current Report on Form 8-K. Financial information for prior periods has been retrospectively adjusted.
