Amortization of intangible assets was $14.1 million and $12.7 million for the three months ended April 30, 2012 and 2011, respectively.There was no impairment of intangible assets for the three months ended April 30, 2012 and 2011.

Intangible assets have been retrospectively adjusted as of January 31, 2012 to reflect measurement period adjustments to the purchase price allocations for several business combinations completed during the fiscal year ended January 31, 2012. These adjustments were identified during the three months ended April 30, 2012, and resulted from new information obtained about facts and circumstances that existed as of the respective acquisition dates. Intangible assets were changed to reduce acquired technology and customer relationships by $0.3 million and $0.4 million, respectively (see Note 5, Business Combinations).
