The Company
 
Vicor Corporation was incorporated in Delaware in 1981. Unless the context indicates otherwise, the term “Company” meansor “Vicor” mean Vicor Corporation and its consolidated subsidiaries. The Company designs, develops, manufactures and markets modular power components and complete power systems, many of which use an innovative, high frequency electronic power conversion technology called “zero current and zero voltage switching.” In April 2003, the Company announced the introduction of a new power system architecture based on an array of proprietary power conversion technologies called Factorized Power Architecture (“FPA”). The Company believes FPA will provide power system designers with enhanced performance at a lower cost than attained with conventional Distributed Power Architecture (“DPA”). The Company’s principal product lines are covered by one or more United States and foreign patents. Power systems, a central element in any electronic system, convert power from a primary power source (e.g., a wall outlet or battery source) into the stable DC voltages that are required by most contemporary electronic circuits.

In 1986, the Company formed Westcor Corporation (“Westcor”). During 1990, Westcor was merged into the Company and became a division. Westcor manufactures configurable products at its location in Sunnyvale, California. In 1987, the Company formed VLT Corporation as its licensing subsidiary. During 2000, the Company reincorporated VLT Corporation in California by merging it with and into VLT, Inc., a wholly owned subsidiary of the Company. In 1990, the Company established a Technical Support Center in Germany. In 1995, the Company established Technical Support Centers in France, Italy, Hong Kong, and England. Also in 1995, the Company established Vicor Integration Architects (“VIAs”), most of which are majority-owned subsidiaries. VIAs provide customers with local design and manufacturing services for turnkey custom power solutions. At December 31, 20052007 there were six (6) VIAs operating in the United States. In 1996, the Company established Vicor B.V., a Netherlands company, which serves as a European Distribution Center. In 1998, the Company acquired the principal assets of the switching power supply businesses owned by the Japan Tobacco, Inc. group and established a direct presence in Japan through a new subsidiary called Vicor Japan Company, Ltd. (“VJCL”). VJCL markets and sells the Company’s products and provides customer support in Japan. In 2001, the Company established Picor Corporation (“Picor”), a subsidiary which designs, develops and markets Power Management Integrated Circuits and related products for use in a variety of power system applications. Picor develops these products to be sold as part of Vicor’s

The Products
 
Power systems are incorporated into virtually all electronic products, such as computers and telecommunications equipment, to convert electric power from a primary source, for example a wall outlet or battery source, into the stable DC voltages required by electronic circuits. Because power systems are arranged in a myriad of application-specific configurations, the Company’s basic strategy is to exploit the density and performance advantages of its technology by offering comprehensive families of economical, component-level building blocks which can be used to configure a power system specific to a user’s needs. In addition to component-level power converters, which serve as modular power system building blocks, the Company also manufactures and sells complete configurable power systems, accessory products, and custom power solutions. The Company operateshas organized its business segments according to its key product lines. The Brick Business Unit segment (“BBU” or “Brick”) designs, develops, manufactures and markets the Company’s modular power converters and configurable products, and includes the operations of the Company’s Westcor division, VIAs and VJCL. The V*I Chip segment consists of V*I Chip Corporation, a wholly owned subsidiary which designs, develops, manufactures and markets the Company’s FPA products. The Picor segment consists of Picor Corporation, a majority-owned subsidiary of Vicor, which designs, develops, manufactures and markets Power Management Integrated Circuits and related products for use in one industry segment: the development, manufacture and salea variety of power conversion components and systems.system applications. Picor develops these products to be sold as part of Vicor’s products or to third parties for separate applications. The Company’s principal product lines include:
Modular Power Converters
Brick Products
 
Modular Power Converters
The Company currently offers four first-generationseven families ofcomponent-level DC-DC power converters: the VI-200, VI-J00, MI-200, MI-J00, Maxi, Mini and MI-J00Micro families. Designed to be mounted directly on a printed circuit board assembly and soldered in place using contemporary manufacturing processes, each family comprises a

comprehensive set of products which are offered in a wide range of input voltage, output voltage and power ratings. This allows end users to select products appropriate to their individual applications. The product families differ in maximum power ratings, performance characteristics, package size and, in certain cases, in target market.
 
Since 1998, the Company has introduced four familiesinput series of its second-generation of high power density,component-level DC-DC converters. converters in three standard packages: the full size (Maxi), the half size (Mini) and the quarter size (Micro), along with military-commercial-off-the-shelf (“MIL-COTS”) products. In 1998, the 48 Volt input familyseries was introduced, which was designed for the telecommunications market as well as for distributed power systems. The products consist of modules with the most popular output voltages in all three of the Company’s second-generation standard packages: the full size (Maxi), the half size (Mini) and the quarter size (Micro). Output power levels from 50 to 500 Watts are covered by these second-generation products. In 1999, this was followed by two additional families:series: a 300 Volt input for off-line (rectified 115 or 230 Volt ac) and distributed power applications, and a 375 Volt input specifically designed for use in power factor corrected systems. This latter familyseries increased the power available to 600 Watts. In 2001, a 24 Volt input familyseries was added to the standard second-generation product line to address additional telecommunications, industrial and defense market opportunities. The Company has undergone a process of converting these products to the new FasTrak platform that was completed in the first quarter of 2006. The conversion to FasTrak has resulted in lower unit costs, improved manufacturing yields, improved field reliability and improved gross margins.
 
The Vicor Design Assistance Computer (“VDAC”), a core component of the Vicor PowerBench tool suite, was introduced for general use in 2000 and is a proprietary system, which enables Vicor’s customers to specify on-line, and verify in real time, the performance and attributes of second-generationits Maxi, Mini, Micro and MIL-COTS DC-DC converters. Using patented technology, VDAC enables the design of second-generation DC-DC converters with any output voltage between 2 and 48 VoltVolts and with any input voltage from 18 to 425 Volt,Volts, with an input voltage range of up to 2.1:1, available in all of the Vicor established brick standards, full-, half- and quarter-size. Output power is selectable over a continuous range of 20 to 500 Watts per module and modules can be configured in fault-tolerant arrays capable of delivering several kilowatts.

Configurable Products
 
Configurable Products
Utilizing its standard converters as core elements, the Company has developed several product families, which provide complete power solutions configured to a customer’s specific needs. These products exploit the benefits of the component-level approach to offer higher performance, higher power densities, lower costs, greater flexibility and faster delivery than traditional competitive offerings.
 
Most process control, information technology (“IT”) and industrial electronic products operate directly off of AC lines. “Off-line” power systems require “front end” circuitry to convert AC line voltage into DC voltage for the core converters. The Company’s off-line AC-DC products incorporate a set of modular front endfront-end subassemblies to offer a complete power solution from AC line input to highly regulated DC output. The product selection includes a low-profile modular design in various sizes and power levels, and a choice of alternatives to conventional “box switchers,” — high power, off-line bulk supplies in industry-standard packages. Voltage and power levels can be either factory or field configurable.
 
Many telecommunications, defense and transportation electronic products are powered from central DC sources (battery plants or generators). The Company’s DC-DC power system choices include a low-profile modular design similar to the corresponding AC-DC system and a rugged, compact assembly for chassis-mounted, bulk power applications.
 
In February 2001, the Company introduced the VIPAC family of power systems, a new class of user defined, modular power solutions. VIPAC is a new type of integrated power system leveraging the latest advances in second-generationMaxi, Mini, and Micro DC-DC converter technology and modular front ends. VIPAC combines application specific front end units, a choice of chassis styles and, in AC input versions, remotely locatedhold-up capacitors to provide fast, flexible and highly reliable power solutions for a wide range of demanding applications.
 
The web-based Vicor Computer Aided Design (“VCAD”), similar in concept to VDAC,tool, also a component of Vicor PowerBench, can be utilized by the customer to specify and verify, in real time, that customer’s desired VIPAC configuration. The VCAD

Vicor PowerBench system enables the design of a custom configured VIPAC product from all available combinations of inputs, outputs, chassis and optional features.
Factorized Power Architecture
Accessory Power System Components
      In April 2003, the Company announced the introduction of a new power system architecture based on an array of proprietary power conversion technologies called Factorized Power Architecture (“FPA”). The Company believes FPA will provide power system designers with enhanced performance at a lower cost than attained with conventional Distributed Power Architecture (“DPA”). Factorized Power maximizes the competitiveness of a power system with a high degree of systems flexibility, power density, conversion efficiency, transient responsiveness, noise performance and reliability. FPA is enabled by power conversion components called V•I Chips or “VICs”. V•I Chips deliver up to 300 Watts of power in a surface-mount (“SMD”) J-lead package occupying less than 0.25 cubic-inch of space, with power densities up to 1,200 Watts per cubic-inch, which represents a seven to eight times improvement over the Company’s second-generation products.
 In May 2003, the Company introduced the first family of products based on this new technology, 48 Volt to 12 Volt Bus Converter Modules (“BCM”) for conventional Intermediate Bus Architecture applications. In July 2003, the Company introduced its first V•I Chiptm Voltage Transformation Module (“VTM”). VTMs are designed to meet the demands of advanced Digital Signal Processors (“DSP”), Field Programmable Gate Arrays (“FPGA”), Application Specific Integrated Circuits (“ASIC”), processor cores and microprocessor applications at the point of load (“POL”) while providing isolation from input to output. They may be paralleled to deliver hundreds of Amperes. In January 2004, the Company announced the availability of the first members of its 48 Volt Intermediate Bus Converter Modules (“IBCs”). Offered in standard 1/4 brick format and operating from a 38-55 Volt DC input, the IBC family consists of ten fixed ratio standard models with nominal outputs from 3 to 48 Volt DC delivering up to 100 Amperes or 600 Watts.

3


      Additional VTM and BCM products were introduced throughout 2004. In November 2004, the Company introduced a new V•I Chip-based product called the “VICBrick”. This consists of a new class of VIC, the Pre-Regulator Module (“PRM”), coupled with a VTM and mounted on an industry standard1/4 brick format printed circuit board. The PRM provides the regulation function and, when combined with the VTM, enables tight control of the voltage delivered to the load. The VICBrick replicates the functionality of standard1/4 brick DC-DC converters while offering the benefits of FPA in a familiar and widely adopted package.
      In 2005, the Company completed the matrix of 48 Volt V•I Chips: the 36-75 Volt input PRM, which can operate from the wide DC input voltages normally encountered in telecommunications systems and the complete line of VTMs compatible with this PRM. With these devices, 48 Volt FPA systems can be implemented with regulated and isolated outputs between 0.8-55 Volt DC. In addition, several V•I Chip specialty products were designed for and delivered to specific customers for them to evaluate for use in potential applications where V•I Chips can enable significant market advantages. Prototypes of the first PRM for the military/defense COTS market were also delivered.
Accessory Power System Components
Accessory power system components, used with the Company’s component-level power converters, integrate other important functions of the power system, facilitating the design of complete power systems by interconnecting several modules. In general, accessory products are used to condition the inputs and outputs of the Company’s modular power components.
 
VI-HAMs (Harmonic Attenuator Modules) are universal-AC-input, power-factor-correcting front ends for use with compatible power converters. VI-AIMs (AC Input Modules) provide input filtering, transient protection and rectification of the AC line. VI-IAMs (Input Attenuator Modules) provide the DC input filtering and transient protection required in industrial and telecommunications markets. VI-RAMs (Ripple Attenuator Modules) condition converter module outputs for extremely low noise systems. In 1998, the Company doubled the power capability of its component-level AC front end, the VI-ARM (AC Rectifier Module). This new front end product is packaged in the same “Micro” package and includes a microcontroller that tracks the AC line to ensure correct operation for domestic or international line voltages. In addition, two accessory products for the 48 Volt input second-generationMaxi, Mini, and Micro family were introduced in 1999: the FiltMod for input filtering and the IAM48 for transient and spike protection. In 2000, the FARM and FIAM were introduced. The FARM combines autoranging AC input capability with filtering to simplify the design of AC-DC systems. The FIAM combines filtering and transient suppression for 48 volt input applications. In 2005, the High-Boost HAM was introduced. This product can be combined with standard second-generationMaxi, Mini and Micro DC-DC converters, greatly improving power density and cost effectiveness in AC-DC designs.
 
Customer Specific Products
Since its inception, the Company has accepted a certain amount of “custom” power supply business. In most cases, the customer was unable to obtain a conventional solution that could achieve the desired level of performance in the available space. By utilizing its component-level power products as core elements in developing most of these products, the Company was able to meet the customer’s needs with a reliable, high power density, total solution. However, in keeping with the Company’s strategy of focusing on sales of standard families of component-level power building blocks, custom product sales have not been directly pursued. The Company has traditionally pursued these custom opportunities through Value-Added-Resellers (“VARs”) and a network of VIAs (see Part I, Item 1 — “Business — The Company”). Most of the VIAs are majority owned by the Company, while VARs are independent businesses. Both VIAs and VARs are distributed geographically and are in close proximity to many of their customers.
V*I Chip Products
In April 2003, the Company announced the introduction of a new power system architecture based on an array of proprietary power conversion technologies called Factorized Power Architecture (“FPA”). The Company believes FPA will provide power system designers with enhanced performance at a lower cost than attained with conventional DPA. Factorized Power maximizes the competitiveness of a power system with a high degree of systems flexibility, power density, conversion efficiency, transient responsiveness, noise performance and reliability. FPA is enabled by power conversion components called V*I Chips or “VICs”. V*I Chips deliver up to 320 Watts of power in a surface-mount (“SMD”) J-lead package occupying less than 0.3 cubic-inch of space, with power densities up to 1,100 Watts per cubic-inch, which represents a seven to eight times improvement over the Company’s Maxi, Mini and Micro products.
In May 2003, the Company introduced the first family of products based on this new technology, 48 Volt to 12 Volt Bus Converter Modules (“BCM”) for conventional Intermediate Bus Architecture applications. In July 2003, the Company introduced its first V*I Chiptm Voltage Transformation Module (“VTM”). VTMs are designed to meet the demands of advanced Digital Signal Processors (“DSP”), Field Programmable Gate Arrays (“FPGA”), Application Specific Integrated Circuits (“ASIC”), processor cores and microprocessor

applications at the point of load (“POL”) while providing isolation from input to output. They may be paralleled to deliver hundreds of Amperes. In January 2004, the Company announced the availability of the first members of its 48 Volt Intermediate Bus Converter Modules (“IBCs”). Offered in standard 1/4 brick format and operating from a38-55 Volt DC input, the IBC family consists of ten fixed ratio standard models with nominal outputs from 3 to 48 Volt DC delivering up to 100 Amperes or 600 Watts.

With these devices, 48 Volt FPA systems can be implemented with regulated and isolated outputs between 0.8-55 Volt DC. In addition, several V•I Chip specialty products were designed for and delivered to specific customers for them to evaluate for use in potential applications where V•I Chips can enable significant market advantages. High voltage (380 volts) BCM products were introduced to provide “power factor correction — to — processor” down conversion. MIL — COTS rated products for defense applications were qualified and released for production in 2007.
Picor Products
In 2002, the MicroRAM (“μµRAM”) was introduced. This product, designed by the Company’s Picor subsidiary, performs a function similar to the VI-RAM product in a smaller package at a lower price. In 2003, Picor introduced two new families of products, the QPO (QuietPowertm — Output Ripple Attenuation SiP) and QPI (QuietPowertm — 12 Amp Active EMI Filter for DC-DC Converters). The QPO performs a similar function to the μRAMµRAM in a smaller, lower cost surface mount package. Different QPO models allow customers to solve unique output noise problems. The QPI filters unwanted Electro-Magnetic Interference (“EMI”) from the input supply bus. The product is targeted at the telecom market and the emerging Advanced Telecommunication Computing Architecture (“ATCA”) segment. In 2004, Picor expanded its QPI product offerings to include several new products targeted at 24 Volt industrial and military COTS voltage bus supplies. In 2005, Picor introduced the QPI-8, the industry’s firstSystem-inSystem-in-a-Package-a-Package (SiP) device designed to integrate the total hot-swap function with an active EMI filter. This integrated device enables live insertion of plug-in cards and simultaneous EMI noise suppression for DC-DC converter applications.

For the years ended December 31, 2005, 20042007, 2006 and 2003,2005, no single customer accounted for more than 10% of net revenues.
Backlog
 
As of December 31, 2005,2007, the Company had a backlog of approximately $38.6$46.7 million compared to $36.3$36.4 million at December 31, 2004.2006. Backlog is comprised of orders for products, which have a scheduled shipment date within the next 12 months. The Company believes that a substantial portion of sales in each quarter is, and will continue to be, derived from orders booked in the same quarter.
Research and Development
 
As a basic element of its long-term strategy, the Company is committed to the continued advancement of power conversion technology and power component product development. The Company’s research and development efforts are focused in four areas: continued enhancement of the Company’s patented technology; expansion of the Company’s families of componentlevel DC-DC converter products; development of the new FPA products and power management integrated circuits; and continued development of configurable products based upon market opportunities. The Company invested approximately $29.5$30.4 million, $26.2$31.4 million and $23.4$29.5 million in research and development in 2005, 20042007, 2006 and 2003,2005, respectively. Investment in research and development represented 16.4%15.5%, 15.3%16.3% and 15.5%16.4% of net revenues in 2005, 20042007, 2006 and 2003,2005, respectively. The Company plans to continue to invest a significant percentage of revenues into research and development.

Manufacturing
 
The Company’s principal manufacturing processes consist of assembly of electronic components onto printed circuit boards, automatic testing of components, wave, reflow and infrared soldering of assembled components, encapsulation of converter subassemblies, final environmental stress screening of certain products and product test using automatic test equipment.
 
The Company continues to pursue itsa strategy based upon the phased acquisitionand/or fabrication, qualification and integration of automated manufacturing equipment to minimize manual assembly processes, reduce manufacturing costs, increase product quality and reliability and ensure its ability to rapidlyenable rapid and effectively

6


expandeffective expansion of capacity, as needed. The strategy is based upon the phased acquisition and/or fabrication, qualification and integration of automated manufacturing equipment. The Company plans to make continuing investments in manufacturing equipment, particularly for the Company’s new FPA products (see Part I, Item I — “The Products — Factorized Power Architecture”). and replacement of aging manufacturing equipment utilized by the Brick Business Unit.
 
Components used in the Company’s products are purchased from a variety of vendors. Most of the components are available from multiple sources. In instances of single source items, the Company maintains levels of inventories it considers to be appropriate to enable it to meet delivery requirements of customers. Incoming components, assemblies and other parts are subjected to several levels of inspection procedures.
 
Compliance by the Company with applicable environmental laws has not had a material effect on the financial condition or results of operations of the Company.
Second-Generation ProductsCompetition
 Revenues of second-generation products increased by 14.1% in 2005 over 2004, unit production increased 8.6%, and orders increased 22.1%. Both first-and second-generation products are sold to similar customers. Gross margins on second-generation products continue to be significantly lower than those of first-generation products, principally due to high depreciation expense associated with second-generation manufacturing equipment. The process of converting second-generation products to the new FasTrak platform is substantially complete, with the last units scheduled for conversion in the first quarter of 2006. The last production and shipment of products based on the original second-generation platform is scheduled for completion in the first quarter of 2006. The conversion to FasTrak has resulted in lower unit costs, improved manufacturing yields, improved field reliability and improved gross margins. The Company is actively working towards continued yield improvement and cost reduction on FasTrak products. There can be no assurance that such volumes, yields or cost reductions can be attained.
Competition
The power conversion industry is highly competitive. Many power supply manufacturers target markets similar to those of the Company. Representative examples of these manufacturers are: Lambda Electronics, a subsidiary of TDK Corporation; the formerLineage Power (formerly Tyco Electronics Power Systems, business unitnow owned by the Gores Group); Artesyn Technologies and Astec Power, subsidiaries of Lucent Technologies, nowEmerson Electric Co., Power-One, Inc., and Murata Power Solutions, a subsidiary of Tyco International, Ltd.; Artesyn Technologies; Astec Power, a subsidiary of Emerson Electric Company; Power-One, Inc.; and C&D Technologies, Inc., Power Electronics Division.Murata Manufacturing Co. Although certain of the Company’s competitors have significantly greater financial and marketing resources and longer operating histories than the Company, the Company believes that it has a strong competitive position, particularly with customers who need small, high density power system solutions requiring a variety of input-output configurations. The Company bases its competitive strategy on technical innovation, product performance, service and technical support, and in offering a broad product line. The principal methods of competition in the markets in which the Company’s products compete are price, performance and the level of service and technical support offered.
Patents
 
The Company believes that its patents afford advantages by building fundamental and multilayered barriers to competitive encroachment upon key features and performance benefits of its principal product families. The Company’s patents cover the fundamental conversion topologies used to achieve the performance attributes of its converter product lines; converter array architectures which are the basis of the products’ “parallelability”; product packaging design; product construction; high frequency magnetic structures; and automated equipment and methods for circuit and product assembly.
 On February 16, 1999, the United States Patent and Trademark Office issued U.S. patent RE36,098 (the “Reissue Patent”) as a reissue of U.S. Patent 4,441,146 (the “Reset Patent”). The Reissue Patent includes original claims 1 through 5 of the Reset Patent plus 38 additional new claims. The claims in the Reissue Patent cover non-coincident active clamp technology in a broadly defined class of single-ended forward converters and enable design of power converters which are smaller and more energy efficient than

7


conventional power supplies. The claims cover, but are not limited to, so-called “zero-voltage switching” technology. The Company believes that its rights under the Reset Patent and the Reissue Patent have been infringed. (see Part I, Item 3 — “Legal Proceedings”).
The Company has been issued 100105 patents in the United States (which expire between 20062008 and 2025), 32and 2 in EuropeFar East (which expire between 2006 and 2017), and 21 in Japan (which expire between 2006 and 2022)2008). The Company also has a number of patent applications pending in the United States, Europe and the Far East. The Company intends to vigorously protect its rights under its patents. Although the Company believes that patents are an effective way of protecting its technology, there can be no assurances that the Company’s patents will prove to be enforceable (see, e.g., Part I, Item 3 — “Legal Proceedings”). While some of the Company’s patents are deemed materially important to the Company’s operations, the Company believes that no one patent is essential to the success of the Company.
Licensing
 
In addition to generating revenue from product sales, licensing is an element of the Company’s strategy for building worldwide product and technology acceptance and market share. In granting licenses, the


7


Company generally retains the right to use its patented technologies, and manufacture and sell its products, in all licensed geographic areas and fields of use. Licenses are granted and administered through the Company’s wholly-owned subsidiary, VLT, Inc., which owns the Company’s patents. Revenues from licensing arrangements have not exceeded 10% of the Company’s consolidated revenues in any of the last three fiscal years.
 On March 28, 2001, the Company announced that its wholly-owned subsidiaries, Vicor Hong Kong Ltd. (“VHK”) and VLT, Inc. (“VLT”), had entered into cooperative agreements with Nagano Japan Radio Company, Ltd. (“NJRC”). On March 18, 2003, NJRC gave VHK and VLT notice of termination of the agreements, effective September 18, 2003. In January 2004, the Company received a final royalty payment from NJRC.
      On October 20, 2003, the Company announced that it entered into a non-exclusive license with Celestica Corporation to manufacture and sell the V•I Chip Product Family. V•I Chips are the building blocks of the new FPA products that Vicor announced in April 2003. In September 2004, the Company was notified that Celestica’s Power Systems division had been acquired by C&D Technologies, Inc. and that the license was being assigned to C&D.
      On June 30, 2004, the Company announced that it had entered into a non-exclusive license with Sony Corporation (“Sony”) to design and manufacture power converters, using V•I Chip technology and Factorized Power, for use within its products and for sale to its customers in certain agreed-upon applications. The license also grants Sony rights to manufacture certain semiconductor components that are used in V•I Chips. Royalties are based upon the value of the licensed converters used or sold.
Employees
 
As of December 31, 2005,2007, the Company employed approximately 1,0701,036 full time and 3078 part time people. The Company believes that its continued success depends, in part, on its ability to attract and retain qualified personnel. Although there is strong demand for qualified technical personnel, the Company has not to date experienced difficulty in attracting and retaining sufficient engineering and technical personnel to meet its needs (see Part I, Item IIA — “Risk Factors”).
 
None of the Company’s employees are subject to a collective bargaining agreement.

Our future operating results are subject to fluctuations.
 
Our future operating results are subject to fluctuations.
Our future operating results may be materially affected by a number of factors, including the level of orders and demand from customers, the timing of new product announcements or introductions by us or our competitors, the ability to achieveand/or maintain yield improvements and cost reductions particularly with FasTrakMaxi, Mini, Micro and FPA products, achieving increased sales of FPA products, changes in the product mix, and changes in economic conditions in the United States and international markets. As a result of these and other factors, we cannot assure you that we will not experience significant fluctuations in future operating results on a quarterly or annual basis.
Our future success depends upon our ability to develop and market leading-edge, cost effective products.
Our future success depends upon our ability to develop and market leading-edge, cost effective products.
 
The power supply industry and the industries in which many of our customers operate are characterized by intense competition, rapid technological change, product obsolescence and price erosion for mature products, each of which could have an adverse effect on our results of operations. If we fail to continue to develop and commercialize leading-edge technologies and products that are cost effective and maintain high standards of quality, our competitive position and results of operations could be materially adversely affected. Specifically, we may not be successful in leveraging the V•V*I Chips in standard products to promote market acceptance of Factorized Power.
Our future operating results are dependent on the growth in our customers’ businesses.
Our future operating results are dependent on the growth in our customers’ businesses.
 
We manufacture modular power components and power systems that are incorporated into our customers’ electronic products. Our growth is therefore dependent on the growth in the sales of our customers’ products as well as the development by our customers of new products. If we fail to anticipate changes in our customers’ businesses and their changing product needs, our results of operations and financial position could be negatively impacted.
If we were unable to use our manufacturing facility in Andover, Massachusetts, we would not be able to manufacture for an extended period of time.
If we were unable to use our manufacturing facility in Andover, Massachusetts, we would not be able to manufacture for an extended period of time.
 
All modular power components, whether for direct sale to customers or for sale to our subsidiaries for incorporation into their respective products, are manufactured at our Andover, Massachusetts production facility. Damage to this facility due to fire, natural disaster, power loss or other events could cause us to cease

manufacturing. Any prolonged inability to utilize all or a significant portion of this facility could have a material adverse effect on our results of operations.
Our conversion of second-generation products to the FasTrak platform may not achieve our anticipated results.
We may not be able to procure necessary key components for our products, or we may purchase too much inventory or the wrong inventory.
 
The process of converting second-generation products to the new FasTrak platform is substantially complete. The conversion to FasTrak has resulted in lower unit costs, improved manufacturing yields, improved field reliability and improved gross margins, while supporting the worldwide RoHS initiative. We cannot assure you that the improved results due to the conversion of second-generation products to the FasTrak platform will continue as expected. During the second quarter of 2005, we provided additional reserves of approximately $1,600,000 for potential obsolete inventory arising from the RoHS initiativepower supply industry, and the conversionelectronics industry as a whole, can be subject to business cycles. During periods of second-generationgrowth, key components required to build our products may become unavailable in the timeframe required for us to the FasTrak platform. The remaining product conversion and RoHS initiativemeet our customers’ demands. Our inability to secure sufficient components to build products for our customers could result in additional reserve requirements and negatively impact our sales and operating results. We may choose to mitigate this risk by increasing the levels of inventory for certain key components. Increased inventory levels can increase the potential risk for excess and obsolescence should our forecasts fail to materialize or if there are negative factors impacting our customers’ end markets. If we purchase too much inventory or the wrong inventory, we may have to record additional inventory reserves or write-off the inventory, which could have a material adverse effect on our gross margins and on our results of operations. Also, once

We depend on third party suppliers and subcontractors to provide components and assemblies used in our products.products, some of which are sole-sourced. If suppliers or subcontractors cannot provide their products or services on time or to our specifications, we may not be able to meet the demand for our products and our delivery times may be negatively affected. In addition, we cannot directly control the quality of the products and services provided by third parties. In order to grow, we may need to find new or change existing suppliers and subcontractors. This could cause disruptions in production, delays in the shipping of product or increases in prices paid to third-parties.
We are exposed to economic, political and other risks through our foreign sales and distributors.
We are exposed to economic, political and other risks through our foreign sales and distributors.
 
International sales have been and are expected to be a significant component of total sales. Dependence on foreign third parties for sales and distribution is subject to special risks, such as foreign economic and political instability, foreign currency controls and market fluctuations, trade barriers and tariffs, foreign regulations and exchange rates. Sudden or unexpected changes in the foregoing could have a material adverse effect on our results of operations.
Our ability to successfully implement our business strategy may be limited if we do not retain our key personnel and attract and retain skilled and experienced personnel.

Our success depends on our ability to retain the services of our executive officers. The loss of one or more members of senior management could materially adversely affect our business and financial results. In particular, we are dependent on the services of Dr. Patrizio Vinciarelli, our founder, Chairman, President and Chief Executive Officer. The loss of the services of Dr. Vinciarelli could have a material adverse effect on our development of new products and on our results of operations. In addition, we depend on highly skilled engineers and other personnel with technical skills that are in high demand and are difficult to replace. Our continued operations and growth depend on our ability to attract and retain skilled and experienced personnel

in a very competitive employment market. If we are unable to attract and retain these employees, our ability to successfully implement our business strategy may be harmed.
We may be unable to adequately protect our proprietary rights, which may limit our ability to compete effectively.
We may be unable to adequately protect our proprietary rights, which may limit our ability to compete effectively.
 
We operate in an industry in which the ability to compete depends on the development or acquisition of proprietary technologies which must be protected to preserve the exclusive use of such technologies. We devote substantial resources to establish and protect our patents and proprietary rights, and we rely on patent and intellectual property law to protect such rights. This protection, however, may not prevent competitors from independently developing products similar or superior to our products. We may be unable to protect or enforce current patents, may rely on unpatented technology that competitors could restrict, or may be unable to acquire patents in the future, and this may have a material adverse affect on our competitive position. In addition, the intellectual property laws of foreign countries may not protect our rights to the same extent as those of the United States. We have been and may need to continue to defend or challenge patents. We have incurred and expect to incur significant costs in and devote significant resources to these efforts which, if unsuccessful, may have a material adverse effect on our results of operations and financial position.
We may face intellectual property infringement claims that could be costly to resolve.
We may face intellectual property infringement claims that could be costly to resolve.
 
We may in the future receive communications from third parties asserting that our products or manufacturing processes infringe on a third party’s patent or other intellectual property rights. In the event a

10


third party makes a valid intellectual property claim against us and a license is not available to us on commercially reasonable terms, or at all, we could be forced to either redesign or stop production of products incorporating that technology, and our operating results could be materially and adversely affected. In addition, litigation may be necessary to defend us against claims of infringement, and this litigation could be costly and divert the attention of key personnel. An adverse outcome in these types of matters could have a material adverse impact on the results of our operations and financial condition.
We may face legal claims and litigation that could be costly to resolve.
We may in the future encounter legal action from customers, vendors or others concerning product warranty or other claims. We have ongoing litigation with several customers and vendors over product warranty matters, which are fully described in Part I, Item 3 — “Legal Proceedings”. Such litigation is costly and diverts the attention of key personnel. An adverse outcome in these current or future matters could have a material adverse impact on the results of our operations and financial condition.
If we fail to develop or maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud or to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified.
Our management determined that we did not maintain effective internal control over financial reporting as of December 31, 2007 and 2006 because a material weakness in internal control over financial reporting existed. A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. Specifically, we determined that our accounting department did not have sufficient experienced personnel and resources with the requisite technical skills to address complex and judgmental accounting, tax and financial reporting matters within the financial statement close process, including accounting for the Company’s related-party investment in Great Wall Semiconductor Corporation, accounting for income taxes, accounting for complex revenue transactions, and accounting for judgmental accrued liabilities.
Our plans to improve the effectiveness of our internal controls and processes are in process. We cannot assure you that the measures we have taken to date or any future measures will remediate the material


10


weaknesses reported by our management. Further, additional deficiencies in our internal controls may be discovered in the future. If we fail to achieve and maintain an effective system of internal controls over financial reporting, we may be unable to accurately report our financial results, prevent or detect fraud, or provide timely and reliable financial information, which could have a material adverse effect on our business, results of operations or financial condition. In fact, the Company did not file its June 30, 2007 and September 30, 2007 quarterly reports onForm 10-Q within the time period specified under the Exchange Act. In addition, in December 2007, the Company’s former Chief Financial Officer transitioned to the position of Vice President of Treasury Services. The Company’s Vice President, Chief Accounting Officer has assumed the role of Interim Chief Financial Officer. The Company is in the process of a search for a new Chief Financial Officer. However, we cannot assure you if or when a new Chief Financial Officer will be hired. Ineffective internal controls could also cause investors to lose confidence in our reported financial information, which would likely have a negative effect on the trading price of our common stock.
If we are unable to obtain required financial information for certain investments on a timely basis, we may not be able to accurately report our financial results in the reports we file or submit under the Exchange Act, within the time periods specified.
The Company is required to account for an investment under the equity method of accounting. The Company has developed processes and controls to ensure proper accounting and reporting for the investment. We cannot assure you that those procedures, processes and controls will be adequate to ensure that we obtain the required information in order to properly account for this investment under the equity method of accounting and allow us to file our reports under the Exchange Act on a timely basis. The lack of timely filing could prevent continued listing of the Company’s common stock on the Nasdaq Global Select Market and could have a significant impact on the trading price of our Common Stock.
The failure of auction rate securities to sell at their reset dates could impact the liquidity of the investment and could negatively impact the carrying value of the investment.
The Company’s short-term investments consist mainly of municipal and corporate debt securities in which a significant portion are invested in auction rate securities, the significant majority of which are student loan backed securities. Auction rate securities are securities that are structured with short-term interest rate reset dates of generally less than ninety days but with longer contractual maturities that range, for our holdings, from 13 to 39 years. At the end of each reset period, investors can typically sell at auction or continue to hold the securities at par. These securities are subject to fluctuations in fair value depending on the supply and demand at each auction. Through March 14, 2008, auctions held for the Company’s auction rate securities with a total aggregate value of approximately $38.0 million failed. As of March 14, 2008, the Company was holding a total of approximately $43.0 million in auction rate securities. While these debt securities are all highly-rated investments, generally with AAA/Aaa ratings, continued failure to sell at their reset dates could impact the liquidity of the investment which in turn could negatively impact the liquidity requirements of the Company. In addition, continued failure to sell at their reset dates could also negatively impact the carrying value of the investment which could lead to impairment charges in future periods should a decline in the value of those securities be other than temporary, which could have a material adverse effect on our financial position and results of operations.
ITEM 1B —Compliance with the EU’s RoHS may not proceed as planned. UNRESOLVED STAFF COMMENTS
 We have elected to comply with the EU directive on the use of certain hazardous substances in electrical and electronic equipment, referred to as RoHS or as the “lead free directive.” We have established a formal plan to make Vicor products compliant with this directive ahead of the designated July 1, 2006 deadline. Compliance will involve working with certain suppliers and customers, may potentially require the redesign of certain products and may require the modification of certain manufacturing processes. As a result, the following situations could negatively impact our results of operations:
Our suppliers may experience increased demand for RoHS compliant components from their customers and therefore, may not be able to meet our specific requirements or delivery schedules, and we may not be able to meet the demand for our products, and our delivery times may be negatively affected.
Customers mandate that they will not accept RoHS directive compliant product, and such requirements could significantly increase the cost of maintaining business with these customers.
Customers’ transition to RoHS compliant product may be unpredictable, and forecast inaccuracy may negatively impact material availability.
The modification of our manufacturing processes may require the additional investment in equipment, which will increase operating expenses. In 2005, we invested approximately $500,000 for new equipment in support of RoHS initiatives.
The conversion over to compliant materials could result in excess supplies of raw materials that are no longer needed for non-compliant products. Additional inventory reserves could be required for such excess materials and would negatively impact our results of operations. During the second quarter of 2005, we provided additional inventory reserves of approximately $600,000 for potential obsolete inventory from the RoHS initiative.
ITEM 1B —UNRESOLVED STAFF COMMENTS
The Company has not received written comments from the Securities and Exchange Commission regarding its periodic or current reports under the Securities Exchange Act of 1934, as amended, that were received 180 days or more before December 31, 20052007 and remain unresolved. There are no unresolved comments from the Securities and Exchange Commission as of December 31, 2007.

ITEM 3 —LEGAL PROCEEDINGS
Vicor and VLT, Inc. (“VLT”), a wholly owned subsidiary of the Company, arehad been pursuing Reset Patent infringement claims directly against Artesyn Technologies (“Artesyn”), Lucent Technologies and Tyco Electronics Power Systems, Inc. (“Lucent / Tyco”) in the United States District Court in Boston, Massachusetts. The lawsuit against Lucent was

11


filed in May 2000 and in April 2001, the Company added Tyco Electronics as a defendant in that lawsuit. The lawsuit against Artesyn was filed in February 2001. In January 2003, the District Court issued a pre-trial decision in each of these patent infringement lawsuits relating to claim construction of the Reset Patent. The District Court’s decisions rejected assertions that the Reset Patent claims are invalid for indefiniteness; and affirmed Vicor’s interpretation of several terms used in the Reset Patent claims. However, the District Court adopted interpretations of certain terms of the Reset Patent claims that are contrary to Vicor’s position. On May 24, 2004, the United States Court of Appeals for the Federal Circuit affirmed the decisions issued in January 2003 by the District Court. Vicor believes that the District Court’s decisions, and the affirmation of these decisions by the Federal Circuit, strengthens its position regarding validity of the patent, but reduces the cumulative amount of infringing power supplies and the corresponding amount of potential damages. The Federal Circuit has referred the proceedings back to the District Court for trials on validity of the Reset Patent and infringement and damages by Lucent, Tyco and Artesyn.
      In the second quarter of 2005,2007, the Company entered into aseparate settlement agreementagreements with Lambda Americas, Inc., successor to Lambda Electronics, Inc.,Artesyn and Lucent/Tyco, under which the Company received a paymentpayments of $2,500,000$1,770,000 in full settlement of the Company’s Reset Patent infringement claims against LambdaLucent/Tyco and Artesyn, and which settled the lawsuits that the Company had filed against Lucent/Tyco in May 2000 and in April 2001, and the lawsuit that the Company had filed against LambdaArtesyn in JuneFebruary 2001.

      In May 2004,settle a lawsuit brought by Ericsson Wireless Communications, Inc. v. Vicor Corporation was filed in Superior Court of the State of California, County of San Diego. The plaintiff has brought an action against the Company claiming unspecified damages for failurein California state court. Under the terms of out-of warranty products previously purchasedthe settlement agreement entered into on March 29, 2007, after a Court ordered mediation, the Company paid $50.0 million to Ericsson, of which $12.8 million was paid by itthe Company’s insurance carriers. Accordingly, the Company recorded a net loss of $37.2 million from the Company. In November 2004,litigation-related settlements in the fourth quarter of 2006.

The Company’s decision to enter into the settlement followed an adverse ruling by the Court in January, 2007 in connection with a settlement between Ericsson filed a First Amended Complaint adding claims againstand co-defendants Exar Corporation a former vendor of the Company. The Company filed cross-claims against Exar,(“Exar”) and third-party claims against Rohm Device USA, LLC (“Rohm”), two of the Company’s component suppliers prior to 2002. The Company’s writ of mandate appeal of this ruling was denied in April, 2007. In September 2007, the Company filed a notice of appeal of the Court’s decision upholding the Ericsson-Exar-Rohm settlement, which is pending.

For the year ended December 31, 20052007 revenues increased to $179,351,000$195,827,000 from $171,580,000 for 2004.$192,047,000 in 2006. The Company had income before taxes of $4,880,000$5,459,000 in 20052007 as compared withto a loss before taxes of $2,403,000$28,090,000 in 2004.2006. The Company reported net income in 20052007 of $3,916,000$5,335,000 as compared withto a net loss of $3,723,000$29,059,000 in 2004,2006, and a diluted income per share of $.09$.13 in 20052007 as compared with a diluted loss per share of $.09$.69 in 2004.2006. The net loss in 2006 was primarily due to a loss from a litigation-related settlement described below.
 
The book to bill ratio for the third and fourth quarters of 20052007 was 1.03:1.17:1 and .95:0.96:1, respectively. The book to bill ratio for the year ended December 31, 20052007 was 1.01:1.05:1 compared with 1.00:0.99:1 in 2004.2006. In light of the fact that bookings and sales can vary significantly from quarter to quarter, the Company does not believe that this quarterly and annual change in the book to bill ratio is indicative of a trend at this time. The Company ended 20052007 with approximately $38.6$46.7 million in backlog compared to $36.3$36.4 million at the end of 2004.2006.
 
The gross margin for 2005 improved2007 decreased to 39.8%40.3% compared with 36.9%42.6% in 2004.2006. The primary components of the decrease in gross margins improved throughoutmargin dollars and percentage were due to product mix and an issue with certain product returns and warranty expense.
As described in Note 7. in the yearNotes to the Consolidated Financial Statements, the Company changed its method of accounting for its investment in GWS from the cost method to the equity method of accounting. As a result, the financial statements for the years ended December 31, 2006, 2005 and 2004 have been retroactively restated to reflect the equity method of accounting, in accordance with APB 18. Loss from equity method investment (net of tax) increased $818,000 to $1,139,000 from $321,000 for 2006. This was principally due to the equity method investment in GWS being adjusted for a decline in value judged to be other than temporary of $620,000 in the second quarter and due to higher levelsequity method investment losses allocated to the Company. Additionally, the Company made an additional $1,000,000 investment in GWS in February 2008. The Company expects that it will take an impairment charge of shipments and increased productivityapproximately $700,000 in the first quarter of 2008 due to manufacturing efficiencies resulting in lower average unit costs, partially offset by an increase in inventory reserves. During the second quarter of 2005, the Company provided additional reserves of approximately $1,600,000 for potential obsolete inventory arising primarily from the EU RoHS initiative and the conversion of second-generation products to the FasTrak platform. In addition, the Company identified other slow-moving and potential obsolete inventory of approximately $1,200,000, of which $300,000 related to raw material inventories in support of pilot production of V•I Chips.investment.
 
In 2005,2007, depreciation and amortization was $17.1$11.6 million, a decrease of approximately $3.8$2.5 million from 2004,2006, and capital additions were $8.9$9.9 million, an increase of approximately $3.9$4.3 million from 2004.2006. Due to assets which either are now or will be fully depreciated in 2006,2008, the Company expects depreciation and amortization to be less in 20062008 than 2005.2007.
 
Inventories decreasedincreased by approximately $9.0$1.1 million or 4.9% to $17.2$23.1 million as compared with $26.2$22.0 million at the end of 2004,2006, primarily due to meet the increased demand.
On February 22, 2007, the Company announced that it had reached an agreement in principle with Ericsson, Inc., to settle a reductionlawsuit brought by Ericsson against the Company in raw materialsCalifornia state court. Under the terms of the settlement agreement entered into on March 29, 2007, after a Court ordered mediation, the Company paid $50.0 million to Ericsson, of which $12.8 million was paid by the Company’s insurance carriers. Accordingly, the Company recorded a net loss of $37.2 million from a concerted effort to reduce inventory levels and an increase in reserves as mentionedthe litigation-related settlements in the gross margin section above.
      Significant attention across many functional areasfourth quarter of the Company continues to be focused on the design, development, introduction and production of the new FPA products (see Part I, Item I — “The Products — Factorized Power Architecture”).

Critical Accounting Policies and Estimates
 
Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates and judgments, including those related to revenue recognition, allowance for doubtful accounts, inventories, investments, intangible assets, income taxes, impairment of long-lived assets, and contingencies and litigation. Management bases its estimates and judgments on historical experience, knowledge of current conditions and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Management believes the following accounting policies involve its more significant judgments and estimates used in the preparation of its consolidated financial statements.
Allowance for Doubtful Accounts
Allowance for Doubtful Accounts
 
The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments, based on assessments of customers’ credit-risk profiles and payment histories. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.
Inventories
Inventories
 
The Company employs a variety of methodologies to estimate allowances for its inventory for estimated obsolescence or unmarketable inventory. Historically, the Company estimated reserves for its inventory, at all significant locations based upon its known backlog and historical usage, and assumptions about future demand and market conditions. InFor the second quarter of 2005, the Company revised its method for estimating inventory reservesCompany’s brick products produced at the Andover location, its principal manufacturing location. The revisedlocation, the model used is based upon a comparison of on-hand quantities to projected demand, such that amounts on hand in excess of three-year projected usage are fully reserved.reserved for inventories of those products. Since V*I Chip products are at a relatively early stage, a one-year projected usage assumption is used. While we have used our best efforts and believe we have used the best available information to estimate future demand, due to uncertainty in the economy and our business and the inherent difficulty in predicting future demand, it is possible that actual demand for our products will differ from our estimates. If actual future demand or market conditions are less favorable than those projected by management, additional inventory reserves for existing inventories may need to be recorded in future periods.
Long-Lived Assets
Short-term and long-term investments
 
The Company’s short-term and long-term investments are classified asavailable-for-sale securities and are recorded at fair value, with the unrealized gains and losses, net of tax, reported in a separate component of stockholders’ equity. The amortized cost of debt securities is adjusted for amortization of premiums and


18


accretion of discounts to maturity. Such amortization, along with interest and realized gains and losses, are included in other income (expense), net. The Company has no trading securities orheld-to-maturity securities.
Through March 14, 2008, auctions held for the Company’s auction rate securities with a total aggregate value of approximately $38.0 million failed. As of March 14, 2008, the Company was holding a total of approximately $43.0 million in auction rate securities, the significant majority of which are student loan backed securities. These municipal and corporate debt securities have their interest rates reset at auction at regular intervals ranging from seven to ninety days. Because of these short term intervals between interest reset dates, the Company monitors the auctions to ensure they are successful, which provides evidence that the recorded values of these investments approximate their fair values. As discussed above, auctions related to substantially all our auction rate securities have failed and if auctions continue to fail such that the securities were deemed to be not liquid, the Company would need to seek other alternatives to determine the fair value of these securities, which may not be based on the quoted market transaction. In addition, due to the Company’s inability to quickly liquidate these investments, the Company may reclassify those investments with failed auctions as long-term assets in its consolidated balance sheet.
Other Investments
The accounting for investment transactions is reviewed for compliance with Accounting Principles Board Opinion No. 18, “The Equity Method for Accounting for Investments in Common Stock” (APB 18) and/or FASB Interpretation No. 46 Revised (FIN 46R), “Consolidation of Variable Interest Entities”. As discussed in Note 7. in the Notes to Consolidated Financial Statements, the Company previously accounted for the investment in Great Wall Semiconductor Corporation (“GWS”) under APB 18 as a cost method investment as management believed it did not have significant influence over GWS. An additional investment in GWS in May 2007 resulted in the Company owning approximately 24% of GWS which management believes, along with other qualitative factors considered, gives the Company significant influence over GWS. As a result of the additional investment, the Company is required to account for the investment in GWS under the equity method of accounting and to retroactively restate its previously issued consolidated financial statements to reflect the equity method of accounting, in accordance with APB 18.
The Company periodically evaluates the investment in GWS to determine if there are any events or circumstances that are likely to have a significant adverse effect on the fair value of the investment, including the net book value of acquired intangible assets and goodwill. Examples of such impairment indicators include, but are not limited to: GWS’ actual results of operations, actual results of operations compared to forecast, working capital requirements, additional third-party equity investment, if any, and other considerations. If we identify an impairment indicator, we will estimate the fair value of the investment and compare it to its carrying value. If the fair value of the investment is less than its carrying value, the investment is impaired and we make a determination as to whether the impairment is other-than-temporary. For other-than-temporary impairments, we recognize an impairment loss equal to the difference between an investment’s carrying value and its fair value. In the second quarter of 2007, the investment was adjusted for a decline in value judged to be other than temporary of $620,000. Deterioration or changes in GWS’ business in the future could lead to such impairment adjustments in future periods and the impairment adjustments may be material. In fact, the Company made an additional $1,000,000 investment in GWS in February 2008, which will increase its ownership in GWS to approximately 30%, for which the Company expects that it will take an impairment charge of approximately $700,000 in the first quarter of 2008.
Long-Lived Assets
Management evaluates the recoverability of the Company’s identifiable intangible assets, goodwill and other long-lived assets in accordance with Statement of Financial Accounting Standards No. 142, “Goodwill

16


and Other Intangible Assets” (FAS 142) and Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (FAS 144), which generally requires that the recoverability of these assets be assessed when events or circumstances indicate a potential impairment. The Company periodically assesses the remaining use of fixed assets based upon operating results and cash flows


19


from operations. Equipment has been written-down as a result of these assessments as necessary. Goodwill is tested for potential impairment at least annually at the reporting unit level.
Stock-Based Compensation
The Company periodically evaluates whether any indicatorsaccounts for stock-based compensation in accordance with Statement of impairment surroundingFinancial Accounting Standards No. 123 (revised 2004), “Share Based Payment” (FAS 123R), which requires that stock-based compensation expense associated with stock options and related awards be recognized in the investmentstatement of income. Determining the amount of stock-based compensation requires us to develop estimates to be used in Great Wall Semiconductor Corporation (“GWS”) are present and, if so, whether any adjustments tocalculating the carryinggrant-date fair value of stock options. We calculate the investmentsgrant-date fair values using the Black-Scholes valuation model. The use of this model requires us to make estimates for the following assumptions: expected volatility, expected term, risk-free interest rate, expected dividend yield and forfeiture rate. Changes in GWS should beany of these assumptions may have an impact on the amount of stock-based compensation recorded. Deterioration or changes in the Company’s or GWS’ business in the future could lead to such impairment adjustments in future periods.
Warranty
Product Warranties
 
The Company generally warrants its products for a period of two years. Vicor maintains allowances for estimated product returns under warranty based upon a review of known or potential product failures in the field and upon historical patterns of product returns. If unforeseen product issues arise or product returns increase above expected rates, additional allowances may be required.
Income Taxes
Income Taxes
 
The Company accounts for income taxes in accordance with Statement of Financial Accounting Standards No. 109, “Accounting for Income Taxes” (FAS 109), which requires that deferred tax assets and liabilities be recognized using enacted rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. FAS 109 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assetassets will not be realized. The Company has assessed the need for a valuation allowance against these deferred tax assets and concluded that a valuation allowance for a significant portion of the deferred tax assets is warranted at December 31, 2005.2007. In reaching this conclusion, the Company evaluated all relevant criteria including the existence of significant temporary differences reversing in the carryforward period, primarily depreciation. The valuation allowance against these deferred tax assets may require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance. In addition, the assessment of the valuation allowance requires the Company to make estimates of future taxable income and to estimate reversals of temporary differences. Changes in the assumptions or other circumstances may require additional valuation allowances if actual reversals of temporary differences differ from those estimates.
 
The Company operatesadopted FASB Interpretation No. 48, “Accounting for Uncertainty in numerous taxing jurisdictions and is, therefore, subject to a variety ofIncome Taxes” (“FIN 48”), on January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income and related taxes. The Company has provided for potential tax liabilities duetaxes recognized in various jurisdictions which it judges to be probable and reasonably estimablean enterprise’s financial statements in accordance with FASB Statement of Financial Accounting Standards No. 5109, “Accounting for Contingencies”Income Taxes”. JudgmentFIN 48 prescribes a two-step process to determine the amount of tax benefit to recognize. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon examination by a tax authority. If the tax position is requireddeemed “more-likely-than-not” to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in determining the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50 percent likelihood of being realized upon ultimate settlement. If the tax position does not meet the “more-likely-than-not” threshold then it is not recognized in the financial statements. In accordance with FIN 48, the Company accrues interest and penalties, if any, related to unrecognized tax benefits as a component of income tax expense and related tax liabilities. In the ordinary courseexpense. The Company’s adoption of business, there are transactions and calculations where the ultimate tax outcome is uncertain. The Company believes it has reasonably estimated its accrued taxes for all jurisdictions for all open tax periods. The Company periodically assesses the adequacyFIN 48 as of its tax and related accruals on a quarterly basis and adjusts appropriately as events warrant and open tax periods close.

Contingencies
Contingencies
From time to time, we receive notices for product failure claims or that our products or manufacturing processes may be infringing the patent or intellectual property rights of others or for other matters. We periodically assess each matter to determine if a contingent liability should be recorded in accordance with Statement of Financial Accounting Standards No. 5, “Accounting for Contingencies” (FAS 5). In making this assessment, we may, depending on the nature of the matter, consult with external legal counsel and technical experts. Based on the information we obtain, combined with our judgment regarding all the facts and

17


circumstances of each matter, we determine whether it is probable that a contingent loss may be incurred and whether the amount of such loss can be reasonably estimated. Should a loss be probable and reasonably estimable, we record a contingent loss in accordance with FAS 5. In determining the amount of a contingentthe loss, we consider advice received from experts in the specific matter, current status of legal proceedings, if any, prior case history and other factors. Should the judgments and estimates made by us be incorrect, we may need to record additional contingent losses that could materially adversely impact our results of operations.operations and financial position.
Year Ended December 31, 20052007 compared to Year Ended December 31, 20042006
 
Net revenues for fiscal 20052007 were $179,351,000$195,827,000, an increase of $7,771,000,$3,780,000, or 4.5%2.0%, as compared to $171,580,000$192,047,000 for the same period a year ago. The increase in net revenues from the prior year resulted primarily from an increase in V*I Chip revenues of $6,099,000 and Picor revenues of $340,000, partially offset by decreases in Brick segment shipments of standard and custom products of $2,657,000. Orders for fiscal year 2007 increased by 8.5% compared with 2006. Subject to continuing demand, the Company expects modest growth in revenues in 2008. The book-to-bill ratio for 2007 was 1.05:1 as compared to 0.99:1 for 2006.
Gross margin for fiscal 2007 decreased $2,827,000, or 3.5%, to $79,009,000 from $81,836,000 in 2006 and decreased as a percentage of net revenues to 40.3% from 42.6%. The primary components of the decrease in gross margin dollars and percentage were due to the product mix and an issue with certain product returns and warranty expense. During the year ended 2007, the Company replaced certain products and established reserves for future replacements of these products, which were manufactured with a purchased component that exhibited an unacceptable failure rate. As a result, gross margin in the year ended December 31, 2007 were negatively impacted by approximately $980,000 from a combination of product returns which affected net revenues and charges to cost of revenues for warranty costs. In addition, cost of revenues increased approximately $713,000 due to the allocation of a portion of Picor non-recurring engineering charges being charged to cost of revenues in 2007 and not research and development.
Selling, general and administrative expenses were $48,919,000 for 2007, an increase of $2,482,000, or 5.3%, over the same period in 2006. As a percentage of net revenues, selling, general and administrative expenses increased to 25.0% from 24.2%. The principal components of the $2,482,000 increase were $1,666,000, or 8.6.%, of increased compensation expense primarily due to annual compensation adjustments in May 2007, $689,000, or 60.1%, of increased audit and tax expenses, $546,000, or 44.6%, of increased travel expenses, $271,000, or 5.8%, of increased commissions due to the increase in net revenues and due to changes in the mix of revenues subject to commissions, $193,000, or 57.3%, of increased outside services and $130,000, or 6.1%, in increased legal fees due to the litigation with Ericsson Wireless Communications, Inc., Exar Corporation and Rohm Device USA, LLC, and Concurrent Computer Corporation (“Concurrent”), which were partially offset by a $718,000 reimbursement payment from its insurance carriers received in the fourth quarter of 2007 in connection with the Concurrent litigation (see Part II — Item 1 — Legal Proceedings). The principal components partially offsetting the above increases were $424,000, or 10.5%, of decreased depreciation and amortization costs, $295,000, or 10.6%, of decreased advertising costs, $151,000, or 35.4%, in decreased employment recruiting expenses and $115,000, or 9.2%, of decreased training expenses.
Research and development expenses decreased $1,009,000, or 3.2%, to $30,372,000 in 2007 from $31,381,000 in 2006 and decreased as a percentage of net revenues to 15.5% from 16.3%. The principal components of the $1,009,000 decrease were $713,000, or 100%, of decreased costs due to the allocation of a portion of Picor non-recurring engineering charges being charged to cost of revenues and not research and development, $425,000, or 16.8%, of decreased costs associated with the VIAs, $155,000, or 8.7%, of


21


decreased facility costs, $119,000, or 7.9%, of decreased depreciation and amortization costs, and $64,000, or 26.6%, of decreased travel expenses. The principal component partially offsetting the above decreases was $529,000, or 2.7%, in increased compensation expense primarily due to annual compensation adjustments in May 2007. The decreased costs associated with the VIAs was primarily due to $397,000 of decreased sub-contract labor costs.
In the second quarter of 2007, the Company entered into separate settlement agreements with Artesyn and Lucent/Tyco, under which, the Company received total payments of $1,770,000 in full settlement of the Company’s Patent infringement claims against Lucent/Tyco and Artesyn, and which settled the lawsuits that the Company had filed against Lucent/Tyco in May 2000 and in April 2001, and the lawsuit that the Company had filed against Artesyn in February 2001. The full amount of the payments, net of a $177,000 contingency fee accrued by the Company for its litigation counsel, has been included in (Gain) loss from litigation-related settlements, net in the accompanying condensed consolidated statement of operations. In December 2007, the Court awarded Exar and Rohm amounts for certain statutory and discovery costs associated with this ruling. The Company accrued $240,000 in the second quarter of 2007 as a result of the Court’s decision, which is included in (Gain) loss from litigation-related settlement, net in the accompanying condensed consolidated statement of operations.
On February 22, 2007, the Company announced that it had reached an agreement in principle with Ericsson, Inc., to settle a lawsuit brought by Ericsson against the Company in California state court. Under the terms of the settlement agreement entered into on March 29, 2007, after a Court ordered mediation, the Company paid $50.0 million to Ericsson, of which $12.8 million was paid by the Company’s insurance carriers. Accordingly, the Company recorded a net loss of $37.2 million from the litigation-related settlements in the fourth quarter of 2006.
The changes in the major components of other income (expense), net were as follows (in thousands):
             
     2006
  Increase
 
  2007  (As restated)  (Decrease) 
 
Interest income $4,484  $5,389  $(905)
Minority interest in net income of subsidiaries  (539)  (562)  23 
Foreign currency gains  186   139   47 
Gain on disposal of equipment  129   67   62 
Other  128   59   69 
             
  $4,388  $5,092  $(704)
             
The decrease in interest income is due to lower average balances on the Company’s cash equivalents and short-term investments, principally due to the $37,200,000 net payment to Ericsson made at the end of March 2007 (see Part II— Item 3- Legal Proceedings). The increase in foreign currency gains is due to favorable exchange rates in 2007 as compared to 2006. The Company’s exposure to market risk for fluctuations in foreign currency exchange rates relates primarily to the operations of Vicor Japan Co. Ltd. (“VJCL”) and changes in the dollar/yen exchange rate. In addition, the functional currency of the Company’s subsidiaries in Europe and Hong Kong is the U.S. dollar.
Income before income taxes was $5,459,000 in 2007 compared to a loss before income taxes of $28,090,000 for 2006.
The benefit for income taxes totaled $(1,015,000) in 2007 as compared to a provision of $648,000 in 2006. The Company’s effective tax rate was (18.6%) and 2.3% in 2007 and 2006, respectively. In 2007, the tax provision includes estimated federal, state and foreign income taxes on the Company’s pre-tax income, estimated federal and state income taxes for certain minority-owned subsidiaries that are not part of the Company’s consolidated income tax returns, and increases in accrued interest for potential liabilities, offset by the expected utilization of foreign net operating loss carryforwards and the release of certain valuation allowances related to temporary book versus tax differences. During the second quarter of 2007 and year ended December 31, 2007, the Company reversed approximately $300,000 of previously unidentified excess


22


tax reserves identified during the quarter. The impact on the second quarter of 2007 and the year ended December 31, 2007, as well as on prior periods, was not material. The expense was also offset by a discrete item of $169,000 representing refunds of interest received and recorded as a benefit during the first quarter of 2007 as final settlement related to the audit of the Company’s federal tax returns for tax years 1994 though 2002 by the Internal Revenue Service and the reduction in the tax reserves discussed below. In 2006, the tax provision included estimated federal, state and foreign income taxes on the Company’s projected annual pre-tax income, estimated federal and state income taxes for certain minority-owned subsidiaries that are not part of the Company’s consolidated income tax returns, offset by the expected utilization of remaining net operating loss carryforwards and certain tax credit carryforwards. For the year ended December 31, 2007 and 2006, the Company reduced its tax reserves by $1,517,000 and $468,000, respectively, due to closing tax periods in certain jurisdictions and other tax reserves no longer considered necessary. The decreases in 2007 and 2006 were partially offset by increases in reserves during the year of approximately $205,000 and $133,000, respectively.
Loss from equity method investment (net of tax) for fiscal year 2007 increased $818,000 to $1,139,000 from $321,000 for 2006. This was principally due to the equity method investment in GWS being adjusted for a decline in value judged to be other than temporary of $620,000 in the second quarter and due to higher equity method investment losses allocated to the Company. As described in Note 7. in the Notes to the Consolidated Financial Statements, the Company changed its method of accounting for its investment in GWS from the cost method to the equity method of accounting. As a result, the financial statements for the years ended December 31, 2006 and December 31, 2005 have been retroactively restated to reflect the equity method of accounting, in accordance with APB 18. The Company made an additional $1,000,000 investment in GWS in February 2008. The Company expects that it will take an impairment charge of approximately $700,000 in the first quarter of 2008 due to the additional investment.
Basic and diluted loss per share was $0.13 for the year ended December 31, 2007, compared to basic and diluted loss per share of $0.69 for the year ended December 31, 2006.
Year Ended December 31, 2006 compared to Year Ended December 31, 2005
Net revenues for fiscal 2006 were $192,047,000, an increase of $12,696,000, or 7.1%, as compared to $179,351,000 for the same period a year ago. The increase in net revenues resulted primarily from an increase in unitBrick segment shipments of standard and custom products of approximately $8,147,000, partially offset by a decrease$11,018,000, along with increases in license revenueV*I Chip and Picor revenues of $376,000.$1,376,000 and $299,000, respectively. Orders for fiscal year 20052006 increased by 6.5%4.6% compared with 2004. Subject to continuing demand and productivity improvements, the Company expects modest growth in revenues and further improvements in gross margins will lead to what we believe will be a profitable 2006.2005. Thebook-to-bill book-to-bill ratio for 20052006 was 1.01:0.99:1 as compared to 1.00:1.01:1 for 2004. Both first- and second-generation products are sold to similar customers.2005.
 
Gross margin for fiscal 20052006 increased $8,119,000,$10,429,000, or 12.8%14.6%, to $81,836,000 from $71,407,000 from $63,288,000 in 20042005 and increased as a percentage of net revenues from 36.9%39.8% to 39.8%42.6%. The primary components of the increase in gross margin dollars and percentage were due to the higher levels of shipments and increased productivity due toincrease in net revenues, an increase in manufacturing efficiencies resulting in lower average unit costs. These increases were partially offset by an increasecosts and significant inventory reserves recorded in inventory reserve expense of approximately $3,700,000 compared to 2004.2005. During the second quarter of 2005, the Company provided additional reserves of approximately $1,600,000 for potential obsolete inventory arising primarily from the EUEuropean Union RoHS initiative and the conversion of second-generation productsMaxi, Mini, Micro and MIL-COTS product families to the FasTrak platform. In addition, the Company identified other slow-moving and potential obsolete inventory of approximately $1,200,000, of which $300,000 was related to raw material inventoriesinventory in support of pilot production of V•V*I Chips.

(“VJCL”) and changes in the dollar/yen exchange rate. In addition, the functional currency of the Company’s subsidiaries in Europe and Hong Kong is the U.S. dollar. The decrease in minority interest in the net income of subsidiaries was due to lower income at certain minority interest entities.

During the third quarter of 2004, the Company provided additional tax expense for potential liabilities related to certain jurisdictions under examination aggregating $950,000, partially offset by a reduction in the tax reserves for certain jurisdictions due to tax periods closing aggregating $650,000. During the fourth quarter of 2003, the Company revised its estimate of the effective tax rate for the year and recorded a tax benefit for a portion of the net operating losses generated in 2003 and, accordingly, revised its estimated effective tax rate applicable to 2003 to an estimated tax benefit of 21.5%. This estimated tax benefit of $5,356,000 was a non-recurring non-cash item representing an increase in the benefit previously estimated by the Company based on the changes in the deductible and taxable temporary differences for 2003. The effect of the change in the estimated effective tax rate on net income was approximately $5,107,000. The corresponding effect on the net income per share was $.12 for the quarter and for the year ended December 31, 2003.

In addition to the amounts shown in the table above, approximately $511,000 of unrecognized tax benefits have been recorded as liabilities in accordance with FIN 48, and we are uncertain as to if or when such amounts may be settled. Related to these unrecognized tax benefits, we have also recorded a liability for potential interest and penalties of approximately $833,000 at December 31, 2007.
The Company’s primary liquidity needs are for making continuing investments in manufacturing equipment, particularly equipment for the Company’s new FPA products.products and replacement of aging manufacturing equipment utilized by the Brick Business Unit. The Company believes that cash generated from operations and the total of its cash and cash equivalents together with other sources of liquidity,and short-term investments will be sufficient to fund planned operations and capital equipment purchases for the foreseeable future. At December 31, 2005,During the quarter ended June 30, 2007, the Company alsomade an additional investment of $1,000,000 in GWS and agreed to a further investment of $1,000,000 if certain conditions were met by November 2007. Those conditions were not met by November 2007. However, the Company did make the additional $1,000,000 investment in February 2008. The additional $1,000,000 investment was approved by the Audit Committee of the Company’s Board of Directors. Additionally, the Company had approximately $929,000$2,047,000 of capital expenditure commitments, principally for manufacturing equipment.equipment as of December 31, 2007.
 
Through March 14, 2008, auctions held the Company’s auction rate securities with a total aggregate value of approximately $38.0 million failed. As of March 14, 2008, the Company was holding a total of approximately $43.0 million in auction rate securities, the significant majority of which are student loan backed securities. These municipal and corporate debt securities have their interest rates reset at auction at regular intervals ranging from seven to ninety days. The funds associated with our auction rate securities that fail auction may not be accessible until a successful auction occurs, a buyer is found outside of the auction process, the security is called, or the underlying securities have matured. Based on our ability to access our cash and other short-term investments and our expected operating cash flows, we do not anticipate the current lack of liquidity will affect our ability to execute our current operating plan.
The Company does not consider the impact of inflation and changing prices on its business activities or fluctuations in the exchange rates for foreign currency transactions to have been material during the last three fiscal years.

ITEM 7A —QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK
The Company is exposed to a variety of market risks, including changes in interest rates affecting the return on its cash and cash equivalents short-term and long-termshort-term investments and fluctuations in foreign currency exchange rates.
 
As the Company’s cash and cash equivalents consist principally of money market securities, which are short-term in nature, the Company’s exposure to market risk on interest rate fluctuations for these investments is not significant. The Company’s short-term and long-term investments consist mainly of municipal and corporate debt securities. These debt securities, are all highly-rated investments, in which a significant portion are invested in auction rate securities, the significant majority of which are student loan backed securities. These auction rate securities have interest rates reset at auction at regular intervals. Through March 14, 2008, auctions held for the Company’s auction rate securities with a total aggregate value of approximately $38.0 million failed. As a result,of March 14, 2008, the Company believeswas holding a total of approximately $43.0 million in auction rate securities. While those debt securities are all highly rated investments, generally with AAA/Aaa ratings, continued failure to sell at their reset dates could negatively

impact the carrying value of the investment which could lead to impairment charges in future periods, should a decline in the value of these securities be other than temporary. The Company does not believe there is minimal market riskwas any impairment to these investments.investments as of December 31, 2007. Our annual interest income would change by approximately $1,000,000$600,000 in 20052007 for each 100 basis point increase or decrease in interest rates.
 
The Company’s exposure to market risk for fluctuations in foreign currency exchange rates relates primarily to the operations of VJCLVicor Japan Company, Ltd. (“VJCL”) and changes in the dollar/yen exchange rate. Relative to foreign currency exposure against the yen existing at December 31, 2005, a 10% unfavorable movement in the dollar/yen exchange rate would increase the foreign currency loss by approximately $200,000. In addition, the functional currency of the Company’s subsidiaries in Europe and Hong Kong is the U.S. Dollar. Therefore, the Company believes that market risk is mitigated since these operations are not materially exposed to foreign exchange fluctuations. Relative to foreign currency exposure against the yen existing at December 31, 2007, a 10% unfavorable movement in the dollar/yen exchange rate would increase foreign currency loss by approximately $200,000.

VICOR CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. DESCRIPTION OF BUSINESS
 
Vicor Corporation (the “Company” or “Vicor”) designs, develops, manufactures and markets modular power converters, power system components, and power systems using a patented, high frequency power conversion technology designated “zero current switching.” The Company also licenses certain rights to its technology in return for ongoing royalties. The principal markets for the power converters and systems are large Original Equipment Manufacturers and smaller, lower volume users which are broadly distributed across several major market areas.
2. SIGNIFICANT ACCOUNTING POLICIES
Principles of consolidation
 
Principles of consolidation
The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation. Certain of the Company’s Vicor Integration Architects (“VIAs”) are not majority owned by the Company. These entities are consolidated by the Company as management believes that the Company has the ability to exercise control over their activities and operations. During 2005, the Company increased the minority interests balance by $697,000, with a corresponding offset to additional paid-in capital, to adjust the balance to reflect the minority interest ownership percentage in the net equity of these subsidiaries.
Revenue recognition
Basis of presentation
 
As described in Note 7., due to an additional investment in Great Wall Semiconductor Corporation (“GWS”) in May 2007, the Company changed its method of accounting for its investment in GWS from the cost method to the equity method of accounting. As a result, the financial statements for the year ended December 31, 2006 and December 31, 2005 have been retroactively restated to reflect the equity method of accounting, in accordance with Accounting Principles Board Opinion No. 18, “The Equity Method of Accounting for Investments in Common Stock”.
Revenue recognition
Product revenue is recognized in the period when persuasive evidence of an arrangement with a customer exists, the products are shipped and title has transferred to the customer, the price is fixed or determinable, and collection is considered probable. License fees are recognized as earned. The Company recognizes revenue on such arrangements only when the contract is signed, the license term has begun, all obligations have been delivered to the customer, and collection is probable. The Company evaluates revenue arrangements with potential multi-element deliverables in accordance with Emerging Issues Task Force (“EITF”) IssueNo. 00-21 “Revenue Arrangements with Multiple Deliverables” (EITF (EITF 00-21).
Foreign currency translation
Foreign currency translation
 
The financial statements of Vicor Japan Company, Ltd. (“VJCL”), for which the functional currency is the Japanese yen, have been translated into U.S. dollars in accordance with FASB Statement No. 52, “Foreign Currency Translation.” All balance sheet accounts have been translated using the exchange rate in effect at the balance sheet date. Income statement amounts have been translated at the average exchange rates in effect during the year. The gains and losses resulting from the changes in exchange rates from year to year have been reported in other comprehensive income. Transaction gains and losses, includingand translation gains (losses) resulting from the remeasurement of foreign currency denominated assets and liabilities of the Company’s foreign subsidiaries where the functional currency is the U.S. dollar are included in other income (expense), net. Foreign currency transaction gains (losses), included in other income (expense), net, were approximately $186,000, $139,000, and ($771,000), $268,000 in 2007, 2006 and $607,000 in 2005, 2004 and 2003, respectively.

2. Cash and cash equivalentsSIGNIFICANT ACCOUNTING POLICIES (Continued)
 
Cash and cash equivalents
Cash and cash equivalents include funds held in checking and money market accounts with banks, certificates of deposit and debt securities with maturities of less than three months when purchased and money market securities. Cash and cash equivalents are valued at cost which approximates market value. The Company’s money market securities, which are classified as cash equivalents on the balance sheet, are purchased and redeemed at par. The estimated fair value is equal to the cost of the securities and due to the

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)
nature of the securities there are no unrealized gains or losses at the balance sheet dates. As of December 31, 2005, approximately $906,000
Restricted cash and short-term investments
Restricted cash and short-term investments represent the amount of cash was restrictedand short-term investments required to be set aside as a guarantee for certain foreign letters of credit. Restricted cash and short-term investments of $1,045,000 as of December 31, 2006, and $906,000 as of December 31, 2005, respectively, were reclassified to conform to the 2007 presentation.
Short-term and long-term investments
Short-term and long-term investments
 
The Company’s short-term and long-term investments are classified asavailable-for-sale securities and are recorded at fair value, with the unrealized gains and losses, net of tax, reported in a separate component of stockholders’ equity. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization, along with interest and realized gains and losses, are included in other income (expense), net. The Company has no trading securities orheld-toheld-to-maturity-maturity securities.
Allowance for doubtful accounts
Through March 14, 2008, auctions held for the Company’s auction rate securities with a total aggregate value of approximately $38.0 million failed. As of March 14, 2008, the Company was holding a total of approximately $43.0 million in auction rate securities, the significant majority of which are student loan backed securities. These municipal and corporate debt securities have their interest rates reset at auction at regular intervals ranging from seven to ninety days. Because of these short term intervals between interest reset dates, the Company monitors the auctions to ensure they are successful, which provides evidence that the recorded values of these investments approximate their fair values. As discussed above, auctions related to substantially all our auction rate securities have failed and if auctions continue to fail such that the securities were deemed to be not liquid, the Company would need to seek other alternatives to determine the fair value of these securities, which may not be based on the quoted market transaction. In addition, due to the Company’s inability to quickly liquidate these investments, the Company may reclassify those investments with failed auctions as long-term assets in its consolidated balance sheet.
 
Allowance for doubtful accounts
The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments, based on assessments of customers’ credit-risk profiles and payment histories. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.
Inventories
Inventories
 
Inventories are valued at the lower of cost (determined using thefirst-in, first-out method) or market. The Company provides reserves for inventories estimated to be excess, obsolete or unmarketable. The Company’s estimation process for such reserves is based upon its known backlog, projected future demand and expected market conditions. If the Company’s estimated demand and or market expectation were to change or if product sales were to decline, the Company’s estimation process may cause larger inventory reserves to be recorded, resulting in larger charges to cost of revenues.

2. Concentrations of credit riskSIGNIFICANT ACCOUNTING POLICIES (Continued)
 
Concentrations of credit risk
Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, short-term and long-term investments and trade accounts receivable. The Company maintains cash and cash equivalents and certain other financial instruments with various high credit, quality financial institutions. The Company’s short-term and long-term investments consist of highly rated (AAA/Aaa) municipal and corporate debt securities in which a significant portion are invested in auction rate securities. As of March 14, 2008, the Company was holding a total of approximately $43.0 million in auction rate securities, the significant majority of which are student loan backed securities. Through March 14, 2008, auctions held for the Company’s auction rate securities with a total aggregate value of approximately $38.0 million failed. The funds associated with our auction rate securities that fail auction may not be accessible until a successful auction occurs, a buyer is found outside of the auction process, the security is called, or the underlying securities have matured. If the credit rating of the issuer of any auction rate security held by us deteriorates, we may be required to adjust the carrying value of the investment for an other than temporary decline in value through an impairment charge. The Company’s investment policy, approved by the Board of Directors, limits the amount the Company may invest in any one type of investment,issuer, thereby reducing credit risk concentrations. Concentrations of credit risk with respect to trade accounts receivable are limited due to the number of entities comprising the Company’s customer base. Credit losses have consistently been within management’s expectations.
Goodwill and intangible assets
Goodwill and intangible assets
 
The Company accounts for its goodwill and other intangible assets in accordance with FASB Statement No. 142, “Goodwill and Other Intangible Assets” (FAS 142), which resulted in the elimination of goodwill amortization beginning in fiscal 2002. The Company performs a test of goodwill for potential impairment at least annually. Values assigned to patents are amortized using the straight-line method over periods ranging from fivethree to twenty years.
Long-lived assets
Long-lived assets
 
In accordance with FASB Statement No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”, long-lived assets such as property, plant and equipment and intangible assets, are included in

impairment evaluations when events or circumstances exist that indicate the carrying amount of those assets may not be recoverable. If the impairment evaluation indicates the affected asset is not recoverable, the asset’s carrying value would be reduced to fair value. No event has occurred that would suggest any impairment in the value of long-lived assets recorded in the accompanying consolidated financial statements.
Other investments
Other investments
 
The accounting for other investment transactions is reviewed for compliance with Accounting Principles Board Opinion No. 18, “The Equity Method for Accounting for Investments in Common Stock” (APB 18) and/or FASB Interpretation No. 46 Revised (FIN 46R), “Consolidation of Variable Interest Entities”. As discussed in Note 7. the Company previously accounted for the investment in Great Wall Semiconductor Corporation (“GWS”) under APB 18 as a cost method investment as management believed it did not have significant influence over GWS. An additional investment in GWS in May 2007 resulted in the Company owning approximately 24% of GWS which management believes, along with other qualitative factors considered, gives the Company significant influence over GWS. As a result of the additional investment, the Company is required to account for the investment in GWS under the equity method of accounting and to retroactively restate its previously issued consolidated financial statements to reflect the equity method of accounting, in accordance with APB 18.

Income taxes
Income taxes
 
The Company accounts for income taxes in accordance with FASB Statement No. 109, “Accounting for Income Taxes” (FAS 109). FAS 109 requires that deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted income tax rates and laws that are expected to be in effect when the temporary differences are expected to reverse. FAS 109 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized. Additionally,

deferred tax assets and liabilities are separated into current and noncurrent amounts based on the classification of the related assets and liabilities for financial reporting purposes or the expected reversal.
Stock-based compensation
The Company usesadopted FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”), on January 1, 2007. FIN 48 clarifies the intrinsic value method in accounting for its employee stock optionsuncertainty in accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (APB 25) and related Interpretations, as permitted under FASB Statement No. 123, “Accounting for Stock-Based Compensation” (FAS 123) and FASB Statement No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure” (FAS 148). Under APB 25, because the exercise price of the Company’s employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized.
      Pro forma information regarding net income (loss) and net income (loss) per share is required by FAS 123, which also requires that the information be determined as if the Company had accounted for its employee stock options granted subsequent to December 31, 1994 under the fair value method describedtaxes recognized in FAS 123. The fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions:
             
Vicor: 2005 2004 2003
       
Risk-free interest rate  3.9%  3.4%  2.6%
Expected dividend yield  .38%      
Expected volatility  .59   .68   .68

Expected dividend yield         
Expected volatility  .43   .43   .45 
Expected lives 6.5 years 6.5 years 6.5 years
      The weighted-average fair value of Vicor options granted was $7.02, $7.05 and $4.62 in 2005, 2004 and 2003, respectively. The weighted-average contractual life for Vicor options outstanding as of December 31, 2005 is 3.2 years.

32


VICOR CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
2. SIGNIFICANT ACCOUNTING POLICIES (Continued)
      The weighted-average fair value of Picor options granted was $.32, $.33 and $.21 in 2005, 2004 and 2003, respectively. The weighted-average contractual life for Picor options outstanding as of December 31, 2005 is 7.1 years.
      The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of subjective assumptions including the expected stock price volatility. Because the Company’s employee stock options have characteristics different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair values of its employee stock options.
      For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options’ vesting period. The following table sets forth a reconciliation of reported net income (loss) to pro forma net income (loss) (in thousands except for earnings per share information):
              
  2005 2004 2003
       
Net income (loss), as reported $3,916  $(3,723) $(19,535)
Total stock-based employee compensation expense determined under fair-value based methods for all awards, net of related tax effects  (845)  (1,983)  (2,935)

Pro forma net income (loss) per share:            
 Basic $.07  $(.14) $(.54)
 Diluted $.07  $(.14) $(.54)
      The above table includes compensation expense for Picor options of $105,000, $96,000 and $60,000 for the years 2005, 2004 and 2003, respectively. The 2004 and 2003 expense has been revised to include these Picor amounts. The fair value of Picor common stock was estimated by obtaining an independent valuation of Picor.
Use of estimates
      The preparation of theenterprise’s financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Comprehensive income
      The Company reports comprehensive income in accordance with FASB Statement No. 130, “Reporting Comprehensive Income” (FAS 130)109, “Accounting for Income Taxes”. FAS 130 requiresFIN 48 prescribes a two-step process to determine the foreign currency translation adjustmentsamount of tax benefit to recognize. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon examination by a tax authority. If the tax position is deemed “more-likely-than-not” to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50 percent likelihood of being realized upon ultimate settlement. If the tax position does not meet the “more-likely-than-not” threshold then it is not recognized in the financial statements. In accordance with FIN 48, the Company accrues interest and penalties, if any, related to VJCL and unrealized gains (losses) on short-term and long-term investments to be included in other comprehensive income, netunrecognized tax benefits as a component of related income tax effects.

In addition, FAS 151 requires that allocation of fixed production overhead to the costs of conversion be based on the normal capacity of the production facilities. The provisions of FAS 151 are effective for fiscal years beginning after June 15, 2005.

FAS 123(R) supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees”, and amends SFAS No. 95, “Statement of Cash Flows”. Generally, the approach in FAS 123(R) is similar to the approach described in FAS 123. However, FAS 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values at the date of grant.

      As permitted by FAS 123, the Company currently accounts for share-based payments to employees using APB Opinion No. 25’s intrinsic value method and, as such, generally recognizes no compensation cost for employee stock options. The Company will be required to adopt FAS 123(R) on January 1, 2006, the commencement of its first quarter of fiscal 2006.

V*I Chip — The Company uses the yield to maturity of a ten-year treasury bond, since all of V*I Chip’s options expire ten years after they are granted.
Expected dividend yield:
Vicor —The Company determines the expected dividend yield by annualizing the most recent prior cash dividends declared by the Company’s Board of Directors and dividing that result by the closing stock price on the date of that dividend declaration. Dividends are not paid on options.
Picor —Picor has not and does not expect to declare and pay dividends in the foreseeable future. Therefore, the expected dividend yield is not applicable.
V*I Chip — V*I Chip has not and does not expect to declare and pay dividends in the foreseeable future. Therefore, the expected dividend yield is not applicable.
Expected volatility:
Vicor —Under FAS 123, Vicor used historical volatility to estimate the grant-date fair value of the options. Under FAS 123(R), Vicor has elected to continue to use historical volatility, using the expected term for the period over which to calculate the volatility (see below). The Company does not expect its future volatility to differ from its historical volatility. The computation of the Company’s volatility is based on a simple average calculation of monthly volatilities over the expected term.
Picor — As Picor is a nonpublic entity, historical volatility information about is not available. As permitted under FAS 123(R), an industry sector index of approximately 5 publicly traded fabless semiconductor firms was developed for calculating historical volatility for Picor. Historical prices for each of the companies in the index based on the market price of the shares on each day of trading over the expected term were used to determine the historical volatility.

Expected term:
Vicor The Company uses historical employee exercise and option expiration data to estimate the expected term assumption for the Black-Scholes grant-date valuation. The Company believes that this historical data is currently the best estimate of the expected term of options, and that generally all groups of our employees exhibit similar exercise behavior.
Picor — Due to the lack of historical information, the “simplified” method prescribed by the Securities and Exchange Commission’s Staff Accounting Bulletin No. 110 was used to determine the expected term.
V*I Chip — Due to the lack of historical information, the “simplified” method prescribed by the Securities and Exchange Commission’s Staff Accounting Bulletin No. 110 was used to determine the expected term.
Forfeiture rate
The amount of stock-based compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. FAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option.
Vicor —The Company currently expects that for Vicor options, based on an analysis of its historical forfeitures, that approximately 80% of its options will actually vest, and therefore has applied an annual forfeiture rate of 7.25% to all unvested options as of December 31, 2007. For 2006, the Company expected 84% of its options would actually vest and applied an annual forfeiture rate of 5.75%. This analysis will be re-evaluated quarterly and the forfeiture rate will be adjusted as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those shares that vest.
Picor — The Company currently expects that for Picor options, based on an analysis of its historical forfeitures, that approximately 89% of its options will actually vest, and therefore has applied an annual forfeiture rate of 3.75% to all unvested options as of December 31, 2007. Since the compensation expense for year ended December 31, 2006 was immaterial, the Company did not apply an estimated forfeiture rate to the compensation expense. This analysis will be re-evaluated quarterly and the forfeiture rate will be adjusted as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those shares that vest.

Through March 14, 2008, auctions held for the Company’s auction rate securities with a total aggregate value of approximately $38.0 million failed. As of March 14, 2008, the Company was holding a total of approximately $43.0 million in auction rate securities, the significant majority of which are student loan backed securities. These municipal and corporate debt securities have their interest rates reset at auction at regular intervals ranging from seven to ninety days. Because of these short term intervals between interest reset dates, the Company monitors the auctions to ensure they are successful, which provides evidence that the recorded values of these investments approximate their fair values. As discussed above, auctions related to substantially all our auction rate securities have failed and if auctions continue to fail such that the securities were deemed to be not liquid, the Company would need to seek other alternatives to determine the fair value of these securities, which may not be based on the quoted market transaction. In addition, due to the Company’s inability to quickly liquidate these investments, the Company may reclassify those investments with failed auctions as long-term assets in its consolidated balance sheet.

7. INVESTMENTS
In August 2003, the Board of Directors approved the investment by the Company of $1,000,000 in non-voting preferred stock of Great Wall Semiconductor Corporation (“GWS”). In March and August 2004, the Audit Committee of the Board of Directors approved additional investments by the Company of $1,000,000 each for a total 2004 investment of $2,000,000 in non-voting preferred stock of GWS. In May 2007, the Audit Committee of the Board of Directors approved an additional investment of $1,000,000 in non-voting convertible preferred stock of Great Wall Semiconductor Corporation (“GWS”) and agreed to an additional investment of $1,000,000 if certain conditions were met by November 2007. Those conditions were not met by November 2007. However, the Company did make the additional $1,000,000 investment in February 2008, which will increase its ownership in GWS to approximately 30%. The additional $1,000,000 investment was approved by the Audit Committee of the Company’s Board of Directors. The Company expects that it will take an impairment charge of approximately $700,000 in the first quarter of 2008. The Company’s total gross investment in GWS was $4,000,000 as of December 31, 2007 and $3,000,000 as of December 31, 2006. GWS designs, develops and manufactures high performance power semiconductors. A director of Vicor is the founder, President, Chairman of the Board, Chief Executive Officer and the majority voting shareholder of GWS. In addition to the investment, the Company and GWS have entered into a cross-license agreement and the Company purchases certain components from GWS. Purchases from GWS were approximately $1,260,000, $387,000, and $384,000 in 2007, 2006 and 2005, respectively. Revenue under the cross-license agreement was not significant in 2007, 2006 and 2005.
The Company considered the requirements of FASB Interpretation No. 46 (revised December 2003 “Consolidation of Variable Interest Entities” (FIN 46R), in accounting for the additional investment in GWS, and determined that GWS is a variable interest entity. However, the Company concluded that it is not the primary beneficiary. As a result, the Company is accounting for the investment under the equity method of accounting in accordance with Accounting Principles Board Opinion No. 18, “The Equity Method for Accounting for Investments in Common Stock” (APB 18). The Company has also considered FIN No. 35, “Criteria for Applying the Equity Method of Accounting for Investments in Common Stock” (FIN 35) andEITF 02-14, “Whether an Investor Should Apply the Equity Method of Accounting to Investments Other Than Common Stock”(EITF 02-14). The additional investment made in May 2007 resulted in the Company owning approximately 24% of GWS which management believes, along with other qualitative factors considered, gives

7. INVESTMENTS (Continued)
the Company significant influence over GWS. In addition, the Company has an option to purchase an additional 1.5% of GWS for $81,000 in connection with technical consulting services. The Company also believes that its investment in GWS represents in-substance common stock. As a result, the additional investment requires the Company to account for the investment in GWS under the equity method of accounting and to retroactively restate its previously issued consolidated financial statements. Previously, the Company accounted for the investment as a cost method investment as management believed it did not have significant influence over GWS. At December 31, 2006 and 2005, the Company owned approximately 17.5% and 18.6%, respectively, of GWS.
In accordance with APB 18, each investment in GWS has been accounted for as a step acquisition using the purchase method of accounting in accordance with Statement of Financial Accounting Standards No. 141, “Business Combinations” (FAS 141). The allocation of the purchase price included acquired intangible assets, including core and developed technology as well as in-process research and development (IPR&D). The excess of the purchase price over the fair value allocated to the net assets is goodwill. The core and developed technology is being amortized over three years. The amounts allocated to IPR&D were charged to expense in accordance with FAS 141, which specifies that the amount assigned to the acquired intangible assets to be used in a particular research and development project that have no alternative future use shall be charged to expense at the acquisition date. The amounts included in other assets in the accompanying consolidated balance sheets related to the net GWS investment were $687,000 and $826,000 as of December 31, 2007 and 2006, respectively, as follows (in thousands):

As a result of the accounting change, retained earnings as of January 1, 2006 decreased by $1,853,000 from $175,660,000 to $173,807,000 due to the expensing of IPR&D of $908,000, the allocation of equity method investment losses of $454,000 and amortization expense for the acquired intangible assets and other of $491,000. This represents the retroactive application of the equity method of accounting for the period from August 2003, the date of the Company’s initial investment in GWS, through December 31, 2005.
The Company periodically evaluates the investment in GWS to determine if there are any events or circumstances that are likely to have a significant adverse effect on the fair value of the investment, including the net book value of acquired intangible assets and goodwill. Examples of such impairment indicators include, but are not limited to: GWS’ actual results of operations, actual results of operations compared to forecast, working capital requirements, additional third-party equity investment, if any, and other considerations. If we identify an impairment indicator, we will estimate the fair value of the investment and compare it to its carrying value. If the fair value of the investment is less than its carrying value, the investment is impaired and we make a determination as to whether the impairment is other-than-temporary. For other-than-temporary impairments, we recognize an impairment loss equal to the difference between an investment’s carrying value and its fair value. During the year ended December 31, 2007, the investment was adjusted for a decline in value judged to be other than temporary of $620,000. Deterioration or changes in GWS’ business in

8. GOODWILL AND OTHER INTANGIBLE ASSETS
The Company accounts for goodwill and other intangible assets under Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets” (FAS 142). Under FAS 142, goodwill and indefinite lived intangible assets are not amortized but are tested for impairment at least annually at the reporting unit level. The Company reassessed the carrying value of its goodwill of approximately $2,000,000 related to the operations of one of its subsidiaries, VJCL, during the fourth quarter of fiscal 2007 as required by the provisions of FAS 142, and determined that there was no impairment to the carrying value. Additionally, the Company has $634,000 and $775,000 of equity method goodwill related to its investment in GWS as of December 31, 2007 and 2006, respectively, as discussed in Note 7 .

The Company has assessed the need for a valuation allowance against its deferred tax assets and concluded that a valuation allowance for a significant portion of the deferred tax assets is warranted at December 31, 20052007 and 2004.2006. In reaching this conclusion, the Company evaluated all relevant criteria including the existence of temporary differences reversing in the carryforward period, primarily depreciation. The valuation allowance against these deferred tax assets may require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance.

The Company filed cross-claims against Exar, and third-party claims against Rohm Device USA, LLC and Rohm Co., Ltd., the original manufacturer(s) of the component which Exar sold to the Company. The Company has denied the claims made against it and intends to vigorously defend the claims made against it.
      On March 4, 2005, Exar filed a declaratory judgment action against Vicor in the Superior Court of the State of California, County of Santa Clara, in which Exar seeks a declaration by the Court that Exar is not obligated to reimburse or indemnify Vicor for any claims brought against Vicor for alleged damages incurred as a result of the use of Exar components in Vicor products. The Company has brought cross-claims against Exar, and third-party claims against Rohm Device USA, LLC and Rohm Co., Ltd., for declaratory judgment. The Company intends to vigorously assert its cross-claims against Exar.
      On August 18, 2005, the Company filed an action in The Superior Court of the Commonwealth of Massachusetts, County of Essex (“the Court”) against Concurrent Computer Corporation (“Concurrent”) in response to a demand made by Concurrent in connection with breach of contract and breach of product warranty claims against the Company. On September 22, 2005, Concurrent filed a Demand For Arbitration with The American Arbitration Association. Concurrent is seeking $1,500,000 in replacement costs, plus incidental, consequential and any other damages to be determined. On March 8, 2006 the Court allowed Concurrent’s motion to compel arbitration. The Company has denied the claims made against it and intends to vigorously defend the claims made against it.
In addition, the Company is involved in certain other litigation and claims incidental to the conduct of its business. While the outcome of lawsuits and claims against the Company cannot be predicted with certainty,

14. SEGMENT INFORMATION
 
Statement of Financial Accounting Standards No. 131, “Disclosures about Segments of an Enterprise and Related Information” (FAS 131), establishes standards for reporting information regarding operating segments in annual financial statements and requires selected information of those segments to be presented in interim financial reports issued to stockholders. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker, or decision-making group, in making decisions on how to allocate resources and assess performance.

VICOR CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
14. SEGMENT INFORMATION (Continued)
The Company’s accounting policies and method of presentation for segments is consistent with that used throughout the consolidated financial statements. Prior to 2007, the Company operated as one business segment.
Upon the incorporation of V*I Chip Corporation as a wholly-owned subsidiary of Vicor in April 2007, the Company has organized its business segments according to its key product lines. The Brick Business Unit segment (“BBU” or “Brick”) designs, develops, manufactures and markets the Company’s modular power converters and configurable products, and includes the operations of the Company’s Westcor division, Vicor Integration Architects (“VIAs”) and Vicor Japan Company, Ltd. (“VJCL”). The V*I Chip segment consists of V*I Chip Corporation, a wholly owned subsidiary which designs, develops, manufactures and markets the Company’s Factorized Power Architecture (“FPA”) products. The Picor segment consists of Picor Corporation, a majority-owned subsidiary of Vicor, which designs, develops, manufactures and markets Power Management Integrated Circuits and related products for use in a variety of power system applications. Picor develops these products to be sold as part of Vicor’s products or to third parties for separate applications.
The segments follow the same accounting policies as described in the Summary of Significant Accounting Policies described in Note 2 of the Notes to Consolidated Financial Statements. The effects of all intersegmentand/or intercompany transactions are eliminated in the consolidated financial statements.
The Company’s chief operating decision maker as defined under FAS 131,evaluates performance and allocates resources based on segment revenues and segment operating income (loss). The operating income (loss) for each segment includes selling, general and administrative and research and development expenses directly attributable to the segment. Certain of the Company’s indirect overhead costs, which include corporate selling, general and administrative expenses, are allocated among the segments based upon an estimate of costs associated with each segment. Assets allocated to each segment are based upon specific identification of such assets, which include accounts receivable, inventories, fixed assets and certain other assets. Corporate assets include cash, cash equivalents, short-term investments, land and buildings associated with operations in Massachusetts, deferred tax assets and other assets.
The following table provides significant segment financial data for the years ended December 31, 2007 and 2006:

ITEM 9A —CONTROLS AND PROCEDURES
Attached as exhibits to thisForm 10-K are certifications of Vicor’s Chief Executive Officer (“CEO”) and Interim Chief Financial Officer (“Interim CFO”), which are required in accordance withRule 13a-14 of the Exchange Act of 1934, as amended (the “Exchange Act”). This “Controls and Procedures” section includes information concerning the controls and controls evaluation referred to in the certifications. Part II, Item 9A(e) of this Form 10-K sets forth the report of Ernst & Young LLP, our independent registered public accounting firm, regarding its audit of Vicor’s internal control over financial reporting and of management’s assessment of internal control over financial reporting set forth below in this section. This section should be read in conjunction with the certifications and the Ernst & Young report for a more complete understanding of the topics presented.
(a)  Evaluation of disclosure controls and procedures.
 
As required byRule 13a-15 under the Exchange Act, the Company’s management conducted an evaluation with the participation of the Company’s CEO and Interim CFO, regarding the effectiveness of the Company’s disclosure controls and procedures, as of the end of the last fiscal year. In designing and evaluating the Company’s disclosure controls and procedures, the Company and its management recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating and implementing possible controls and procedures. Based upon that evaluation, theour management, including our CEO and Interim CFO, has concluded that they believe the Company’sour disclosure controls and procedures are reasonablywere not effective to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.forms because of the material weakness described in item (b) below. A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. We intend to continue to review and document our disclosure controls and procedures, including our internal controls and procedures for financial reporting, and we may from time to time make changes to the disclosure controls and procedures to enhance their effectiveness and to ensure that our systems evolve with our business.
(b)  Management Report on Internal Control Over Financial Reporting
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.
 
Management assessed our internal control over financial reporting as of December 31, 2005,2007, the end of our fiscal year. Management based its assessment on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.Commission (“COSO”). Management’s assessment included evaluation of such elements as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment.

49


 Based on our assessment, management has concluded that our internal control over
As of December 31, 2007, the Company’s accounting department did not have sufficient experienced personnel and resources with the requisite technical skills to address complex and judgmental accounting, tax and financial reporting matters as part of its financial statement close process.
As a result, the Company’s financial statement close process was not effective as of December 31, 20052007 as it relates to provide reasonable assurance regarding the reliability ofevaluating and accounting for complex and judgmental accounting, tax and financial reporting matters, including accounting for the Company’s related-party investment in Great Wall Semiconductor

Corporation, accounting for income taxes, accounting for complex revenue transactions, and the preparationaccounting for judgmental accrued liabilities. Management views these matters as a material weakness as of December 31, 2007 as this control deficiency could have resulted in a material misstatement of our interim or annual consolidated financial statements for externalthat would not have been prevented or detected in a timely manner.
Because of the material weakness discussed above, management has concluded that the Company did not maintain effective control over financial reporting purposesas of December 31, 2007, based on the criteria in accordance with generally accepted accounting principles.the Internal Control — Integrated Framework issued by COSO.
 
Our independent registered public accounting firm, Ernst & Young LLP, audited management’s assessment and independently assessed the effectiveness of the Company’s internal control over financial reporting. Ernst & Young has issued an attestation report which is included at Item 9A(e) of thisForm 10-K.
(c)  Inherent Limitations on Effectiveness of Controls
 
The Company’s management, including the CEO and Interim CFO, does not expect that our Disclosure Controls or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.
(d)  Change in Internal Control Over Financial Reporting
 There
Other than the items noted below, there was no change in the Company’s internal control over financial reporting that occurred during the fiscal quarter ended December 31, 20052007 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
Our remediation efforts related to the material weakness which existed as of December 31, 2006 and noted in Item 9A(b) of the 2006 Annual Report onForm 10-K filed on March 15, 2007 were not complete, though certain objectives under the Company’s remediation plan were accomplished in 2007. This included the addition of two individuals to the accounting staff. One individual began working with the Company in June 2007 and the second individual, a new Vice President, Corporate Controller, began working with the Company at the end of August 2007. In a separate development, though, in December 2007 the Company announced that Mark A. Glazer, Chief Financial Officer, Treasurer, and Secretary transitioned to the position of Vice President of Treasury Services. Richard J. Nagel, Jr., Vice President, Chief Accounting Officer assumed the role of Interim Chief Financial Officer. The Company is in the process of a search for a new Chief Financial Officer, which it expects will take several months to complete.
We have implemented or intend to implement during fiscal 2008, the following measures to remediate the material weakness in internal control over financial reporting noted in Item 9A(b) above:
• Complete the process of hiring a new Chief Financial Officer.
• Perform an overall assessment of the staffing requirements for the accounting department and add resources to our corporate accounting function to assist in evaluating complex and judgmental accounting, tax and financial reporting issues.
As of March 17, 2008, our remediation efforts related to the material weakness which existed as of December 31, 2007 were not complete. Our efforts to remediate the material weakness will continue during fiscal 2008.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders
Vicor Corporation
 
We have audited management’s assessment, included in the accompanying Management Report on Internal Control Over Financial Reporting, that Vicor Corporation maintained effectiveCorporation’s internal control over financial reporting as of December 31, 2005,2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Vicor Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting.reporting included in the accompanying Management Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the company’s internal control over financial reporting based on our audit.
 
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment,assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 
A material weakness is a deficiency, or combination of deficiencies in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment. As of December 31, 2007, the Company’s accounting department did not have sufficient experienced personnel and resources with the requisite technical skills to address complex and judgmental accounting, tax and financial reporting matters as part of its financial statement close process. As a result, the Company’s financial statement close process was not effective as of December 31, 2007 as it relates to evaluating and accounting for complex and judgmental accounting, tax and financial reporting matters, including accounting for the Company’s related-party investment in Great Wall Semiconductor Corporation, accounting for income taxes, accounting for complex revenue transactions and accounting for judgmental accrued liabilities. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2007 consolidated financial statements, and this report does not affect our report dated March 14, 2008 on those consolidated financial statements.
In our opinion, management’s assessment thatbecause of the effect of the material weakness described above on the achievement of the objectives of the control criteria, Vicor Corporation has not maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, Vicor Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005,2007, based on the COSO criteria.
 We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Vicor Corporation as of December 31, 2005 and 2004 and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2005 of Vicor Corporation and our report dated
