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 our 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 twelve months ended January 31, 2015 and a deferred payment valued at $4,471.

The identified intangible assets acquired consisted of purchased 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.

Other acquisitions for the twelve months ended January 31, 2015 consisted of four privately-held companies which were accounted for as business combinations. These acquisitions were not material individually or in the aggregate.

The separate results of operations for the acquisitions during the twelve months ended January 31, 2015 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.
