Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill

The Company has two reporting units: (1) Unified Service Delivery and (2) Test Automation. As of September 30, 2013 and March 31, 2013, goodwill attributable to the Unified Service Delivery reporting unit was $200.5 million and $199.5 million, respectively. Goodwill attributable to the Test Automation reporting unit was $2.4 million and $3.0 million as of September 30, 2013 and March 31, 2013, respectively. Goodwill is tested for impairment at a reporting unit level at least annually, or on an interim basis if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting segment below its carrying value.

The changes in the carrying amount of goodwill for the six months ended September 30, 2013 are due to purchase accounting adjustments and the impact of foreign currency translation adjustments related to asset balances that are recorded in non-U.S. currencies.

The changes in the carrying amount of goodwill for the six months ended September 30, 2013 are as follows (in thousands):



	Six months ended

Intangible Assets

The net carrying amounts of intangible assets were $60.9 million and $63.8 million as of September 30, 2013 and March 31, 2013, 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 which resulted from the Network General Central Corporation (Network General) acquisition, which has an indefinite life and thus is not amortized. The carrying value of the indefinite lived trade name is evaluated for potential impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired.

Intangible assets include an indefinite lived trade name with a carrying value of $18.6 million and the following amortizable intangible assets as of September 30, 2013 (in thousands):
