Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill

The Company has two reporting units: (1) Unified Service Delivery and (2) Test Optimization. As of September 30, 2014 and March 31, 2014, goodwill attributable to the Unified Service Delivery reporting unit was $199.1 million and $201.0 million, respectively. Goodwill attributable to the Test Optimization reporting unit was $2.4 million as of September 30, 2014 and March 31, 2014. 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 unit below its carrying value.

The change in the carrying amount of goodwill for the six months ended September 30, 2014 is due to the impact of foreign currency translation adjustments related to asset balances that are recorded in currencies other than the U.S. Dollar.

The changes in the carrying amount of goodwill for the six months ended September 30, 2014 are as follows (in thousands):

Intangible Assets

The net carrying amounts of intangible assets were $54.5 million and $58.5 million as of September 30, 2014 and March 31, 2014, 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.

During the fiscal year ended March 31, 2014, the Company acquired certain rights to Accanto Systems, S.r.l. (Accanto) software not previously purchased as part of the acquisition transaction in fiscal year 2013 for $500 thousand. This amount is included within developed technology and is being amortized using the economic benefit method and a useful life of 6.3 years.

During the fiscal year ended March 31, 2014, the Company acquired a certain technology license for $300 thousand. This amount is included within developed technology as of March 31, 2014 and is being amortized using the economic benefit method and a useful life of 3 years.
