Goodwill

The carrying amount of goodwill was $141.4 million and $128.2 million as of June 30, 2011 and March 31, 2011. The Company's goodwill resulted from the acquisition of Psytechnics in April 2011, Network General Central Corporation (Network General) in November 2007, the acquisition of substantially all of the assets of Quantiva, Inc. in April 2005 and the acquisition of NextPoint Networks, Inc. in July 2000.

Intangible Assets

The net carrying amounts of intangible assets were $50.5 million and $47.7 million as of June 30, 2011 and March 31, 2011, respectively. Intangible assets acquired in a business combination are recorded under the acquisition method of accounting at their estimated fair values at the date of acquisition. The Company amortizes intangible assets over their estimated useful lives, except for the acquired trade name resulting from the Network General acquisition, which has an indefinite life and thus is not amortized. The carrying value of the indefinite lived trade name will be evaluated for potential impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired.

 

The following is the expected future amortization expense as of June 30, 2011 for the years ended March 31 (in thousands):
