Schedule of Recognized Identified Assets Acquired and Liabilities Assumed [Table Text Block]

The fair value of consideration transferred to acquire Radiant was allocated to the identifiable assets acquired and liabilities assumed based upon their estimated fair market values as of the date of the Merger as set forth below. This allocation is preliminary and reflects the best estimate for conditions existing as of August 24, 2011. The primary areas of the purchase price allocation that are not yet finalized relate to determining the fair values of deferred taxes and tax contingencies, and calculating any necessary adjustment to the residual goodwill.

In millions
Purchase Consideration		Net Tangible Assets Acquired/(Liabilities Assumed)		Purchased Intangible Assets		Goodwill
$	1,206	$	84	$	319	$	803

Schedule of Finite-Lived Intangible Assets Acquired as Part of Business Combination [Table Text Block]

The intangible assets acquired in the Merger include the following:

	Estimated Fair Value			Weighted Average Amortization Period(1)
	(In millions)			(years)
Reseller Network		88		13
Technology - Software and Hardware		106		6
Trademarks		48		9
Direct customer relationships		74		15
Noncompete agreements		2		2
Internally developed software		1		2
Total acquired intangible assets		$	319

⁽¹⁾  Determination of the weighted average amortization period of the individual categories of intangible assets was based on the nature of the applicable intangible asset and the expected future cash flows to be derived from the intangible asset. Amortization of intangible assets with definite lives is recognized over the period of time the assets are expected to contribute to future cash flows.
