Business Combinations

6 Months Ended

Business Combinations

(4) Business Combinations—For each business we acquire, the excess of the fair value of the consideration transferred over the fair value of the net tangible assets acquired and net tangible liabilities assumed has been allocated to various identifiable intangible assets and goodwill. Identifiable intangible assets typically consist of purchased technology and customer-related intangibles, which are amortized to expense over their useful lives. Goodwill, representing the excess of the purchase consideration over the fair value of net tangible and identifiable intangible assets, is not amortized.

During the six months ended July 31, 2011, we acquired one privately-held company, which was not material to the financial statements, for a total consideration of $1,890.

The separate results of operations for the acquisition during the six months ended July 31, 2011 were not material to the financial statements compared to our overall results of operations and accordingly, pro-forma financial statements of the combined entities have been omitted.
