Segment Information [Abstract]

Segment Information

12. Segment Information

The Company reports in six segments which correspond to the way the Company manages its business and interacts with customers. These reportable segments, which correspond to operating segments include:

Power Management Devices ("PMD") - The PMD segment provides high performance power MOSFETs which include the lowest R_DS(on) and widest range of packages up to 250V within the power management semiconductor industry for a range of applications including power supply, data processing, telecommunications, industrial, and commercial battery-powered systems.  Key products sold by the PMD segment include, Trench HEXFET^®MOSFETs, Discrete HEXFET^®MOSFETs, Dual HEXFET^®MOSFETs, FETKY^®s, and DirectFET^®s.

Energy Saving Products ("ESP") – The ESP segment provides integrated design platforms that enable the Company's customers to add energy-conserving features to help achieve lower operating energy and manufacturing costs.  The Company's integrated design platforms incorporate its silicon packaging technology to help improve system performance.  The ESP segment's primary market applications include motor control appliances, industrial automation, lighting and display, audio and video. The ESP segment's key products include the Company's analog HVICs and IGBT platforms, digital control ICs and IRAM integrated power modules.

Automotive Products ("AP") - The AP segment provides high performance and energy saving solutions for a broad variety of automotive systems, ranging from typical 12V power net applications up to 1200V hybrid electric vehicle applications.  The Company's automotive expertise includes supplying products for various automotive applications including AC and DC motor drives of all power classes, actuator drivers, automotive lighting (such as high intensity discharge lamps), direct fuel injection for diesel and gasoline engines, hybrid electric vehicle power train and peripheral systems for micro, mid, full and plug-in hybrids for electric vehicles, as well as for body electronic systems like glow plugs, Positive Temperature Coefficient ("PTC") heaters, electric power steering, fuel pumps, Heating Ventilation and Air Conditioning ("HVAC") and rear wipers.  The Company's automotive product designs are used in application‑specific solutions, application‑specific integrated circuits ("ASICs") and application‑specific standard parts ("ASSPs") and generic high volume products for multiple original equipment manufacturer ("OEM") platform usage.  Key products sold by the AP segment include HVICs, intelligent power switch ICs, power MOSFETs including DirectFET^® and IGBTs.

Enterprise Power ("EP") – The EP segment's primary applications include servers, storage, routers, switches, infrastructure equipment, notebooks, graphic cards, and gaming consoles.  The Company offers a broad portfolio of power management system products that deliver benchmark power density, efficiency and performance. These products include the Company's DirectFET® discrete products, CHil digital PWM controllers, power monitoring products, XPhase®, SupIRBuckTM, iPOWIR® voltage regulators, Low voltage ICs, and PowIRstagesTM.

HiRel - The HiRel segment provides high-reliability power components and sub-assemblies designed to address power management requirements in mission critical applications including satellites and space exploration vehicles, military hardware and other high reliability applications such as commercial aircraft, undersea telecommunications, and oil drilling in heavy industry and products used in biomedical applications.  The Company's HiRel segment has a legacy of more than thirty years of experience in many of these market segments, has developed strategic relationships with major system integrators worldwide and has the knowledge, technology and processes required to meet the requirements of customers in the high-reliability markets.  Key products of the HiRel segment include RAD-Hard discretes, RAD-Hard ICs, power management modules and DC-DC converters.

Intellectual Property ("IP") - The IP segment includes revenues from the sale and/or licensing of the Company's technologies and manufacturing process know-how, in addition to the operating results of the Company's patent licensing and settlements of claims brought against third parties.  The Company from time to time enters into opportunistic sale and/or licensing arrangements that it believes are consistent with its business strategy.

12. Segment Information (Continued)

The Company does not allocate assets, sales and marketing, information systems, finance and administrative costs and asset impairment, restructuring and other charges to the operating segments, as these are not meaningful statistics to the CEO in making resource allocation decisions or in evaluating performance of the operating segments.  Because operating segments are generally defined by the products they design and sell, they do not make sales to each other.

The Company does not directly allocate assets to its operating segments, nor does the CEO evaluate operating segments using discrete asset information.  However, depreciation and amortization related to the manufacturing of goods is included in gross profit for the segments as part of manufacturing overhead.  Due to the Company's methodology for cost build up at the product level, it is impractical to determine the amount of depreciation and amortization included in each segment's gross profit.

The Company's "Customer Segments" includes PMD, ESP, AP, EP and HiRel reporting segments.

For the three and nine months ended March 24, 2013 and March 25, 2012, revenues and gross margin by reportable segments were as follows (in thousands, except percentages):
