The non-GAAP results the Company provides exclude the effects of accelerated depreciation, asset impairment, inventory write-offs associated with our El Segundo fab closure, restructuring costs, severance costs, impairment of goodwill, amortization of intangibles, the associated net tax effects of these items, and discrete tax provisions and benefits. The Company excludes any tax provisions (benefits) that are not directly related to ongoing operations and which are either isolated or cannot be expected to occur again with any regularity or predictability.

A reconciliation of these non-GAAP measures to the Company’s reported net income (loss), gross margin (referred to as gross profit in attached schedules) and operating income (loss) in accordance with U.S. GAAP are set forth in the attached schedules below and on our web-site at www.investor.irf.com.

September Quarter Outlook

Mr. Khaykin noted: “Looking ahead to the September quarter which is a typical 13-week period, we see modest growth compared with a normalized 13-week June quarter as demand across our end markets remains stable. As such, we continue to see strong gross margin leverage from rising utilization and manufacturing efficiencies. As a result, we currently expect revenue for the September quarter to range between $260 million to $268 million and GAAP gross margin to range between 33% and 34%.”
