[1] For additional discussion on goodwill impairment, see Note 4, “Goodwill and Intangible Assets,” of the Notes to Condensed Consolidated Financial Statements.

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