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 is 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.

Acquisitions during the three months ended April 30, 2014

	Total Consideration		Net Tangible Assets Acquired		Identifiable Intangible Assets Acquired		Goodwill
Berkeley Design Automation, Inc.	$	51,303	$	2,335	$	24,770	$	24,198

On March 20, 2014, we acquired for cash all of the outstanding common shares of Berkeley Design Automation, Inc. (BDA), a leader in nanometer analog, mixed signal, and radio frequency circuit verification. The acquisition of BDA aligns with Mentor's goal to deliver technologies with superior performance and automation for the growing challenges of Analog/Mixed-Signal verification. The total cash consideration consisted of $46,832 paid during the quarter ended April 30, 2014 and a deferred payment valued at $4,471.

The identified intangible assets acquired consisted of purchase technology with a fair value of $11,200 and other intangibles with a fair value of $13,570. The fair values of the identified intangible assets were valued using an income approach with significant unobservable inputs (Level 3). The significant unobservable inputs include annual revenue derived from each identified intangible asset and a selected discount rate of 15%. We are amortizing purchased technology to cost of revenues over five years and other intangibles to operating expenses over two to five years. The goodwill created by the transaction is not deductible for tax purposes. Key factors that make up the goodwill created by the transaction include expected synergies from the combination of operations and products and the knowledge and experience of the acquired workforce.

The separate results of operations for the acquisition during the three months ended April 30, 2014 were not material, individually or in the aggregate, compared to our overall results of operations and accordingly pro forma financial statements of the combined entities have been omitted.
