Non-GAAP Financial Measures

We have reported our financial results in accordance with generally accepted accounting principles (“GAAP”). A reconciliation of the following non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with GAAP are set forth below:

Adjusted Revenue

We discussed the revenue growth for the year ended December 31, 2008 using non-GAAP financial measures. To understand trends in the business, we believe that it is helpful to adjust the revenue growth rates to illustrate the impact of the acquisition of GIS by including their estimated revenue for the comparable 2007 and 2006 periods. We refer to this adjusted revenue as “As Adjusted” in the following reconciliation table. Revenue “As Adjusted” adds GIS’s revenues from January 1, 2006 to May 8, 2007 to our 2006 and 2007 reported revenue. Management believes these measures give investors an additional perspective on revenue trends, as well as the impact to the Company of the acquisition of GIS that was completed in May 2007.

Adjusted Effective Tax Rate

The effective tax rate for the year ended December 31, 2008 is discussed using non-GAAP financial measures that exclude the effects of charges associated with an equipment write-off; second, third and fourth quarter 2008 restructuring and asset impairments; certain litigation matters and the settlement of certain previously unrecognized tax benefits. Management believes that it is helpful to exclude these effects to better understand and analyze the current period’s effective tax rate given the discrete nature of these items.

		Year Ended December 31, 2008
(in millions)		Pre-Tax Income				Income Taxes				Effective Tax Rate
As Reported		$	(114	)		$	(231	)		202.6%
Restructuring and asset impairment charges			426				134
Equipment write-off			39				15
Litigation			774				283
Tax settlements			—				41
As Adjusted		$	1,125			$	242			21.5%

Management believes that these non-GAAP financial measures provide an additional means of analyzing the current period results against the corresponding prior period results. However, these non-GAAP financial measures should be viewed in addition to, and not as a substitute for, the Company’s reported results prepared in accordance with GAAP.
