[2] In the second quarter of fiscal year 2014, the Company made a strategic shift in the allocation of its engineering resources and has reduced its investment in the hardware-based Brocade ADX® products and increased investment in the software-based Brocade ADX products for Layer 4-7 applications. As a result of this change in strategy, the Company expects hardware-based Brocade ADX and related support revenue to be negatively impacted. Based on these changes in estimates, the Company recognized an impairment charge during the second fiscal quarter of 2014 because the book value of its Application Delivery Products (“ADP”) reporting unit net assets, which includes the Brocade ADX products, exceeded the estimated fair value of these assets. The goodwill amount related to the Company’s other reporting units was not impacted.
