Additional information required by this item is incorporated herein by reference to Note 12, “Segment Information,” of the Notes to Consolidated Financial Statements, included in Part IV, Item 15 of this report

Industry Background

High-Performance Interconnect Market Overview

Computing and storage systems such as servers, supercomputers and storage arrays handling large volumes of data require high-performance interconnect solutions which enable fast transfer of data and efficient sharing of

resources. Interconnect solutions are based on ICs that handle data transfer and associated processing which are added to server, storage, communications infrastructure equipment and embedded systems by either integrating the ICs on circuit boards or by inserting adapter cards containing these ICs into slots on the circuit board.

Interconnect solution requirements, such as high-bandwidth, low-latency (response time), reliability, scalability and price/performance, generally depend on the systems and the applications they support. High-performance interconnect solutions are used in the following markets:


	•	Enterprise Data Center or EDC. EDCs are facilities that house both virtualized and non-virtualized servers, storage and communication infrastructure equipment and embedded systems that enable deployment of commercial applications, such as customer relationship management, financial trading and risk management applications, enterprise resource planning,E-commerce and web service applications. EDCs typically provide multiple data processing and storage resources to one or many organizations and are capable of supporting several applications at the same time.

	•	High-Performance Computing or HPC. HPC encompasses applications that utilize the computing power of advanced parallel processing over multiple servers, commonly called a supercomputer. The expanding list of HPC applications includes financial modeling, government research, computer automated engineering, geosciences and bioscience research and digital content creation. HPC systems typically focus data processing and storage resources on one application at a time.

	•	Embedded. Embedded applications encompass computing, storage and communication functions that use interconnect solutions contained in a chassis which has been optimized for a particular environment. Examples of embedded applications include storage and data acquisition equipment, military operations, industrial and medical equipment and telecommunications and data communications infrastructure equipment.

A number of semiconductor-based interconnect solutions have been developed to address different applications. These solutions include proprietary technologies as well as standard technologies, including Fibre Channel, Ethernet and most recently InfiniBand, which was specifically created for high-performance computing, storage and embedded applications.

Trends Affecting High-Performance Interconnect

Demand for computing power and data storage capacity is rising, fueled by the increasing reliance on enterprises on information technology, or IT, for everyday operations. The increase in compute resources for virtual product design, the increase in online banking and electronic medical records for healthcare and government regulations requiring digital records retention require increased IT capacity. Due to greater amounts of information to be processed, stored and retrieved, data centers rely on high-performance computing and high-capacity storage systems to optimize price/performance, minimize total cost of ownership, utilize power efficiently and simplify management. We believe that several IT trends impact the demand for interconnect solutions and the performance required from these solutions. These trends include:


	•	Transition to blade systems, clustered computing and storage using connections among multiple standard components. Historically, enterprises addressed the requirements for high-end computing and storage using monolithic systems, which are based on proprietary components. These systems typically require significant upfront capital expenditures as well as high ongoing operating and maintenance expense. More recently, enterprises have deployed systems with multipleoff-the-shelf standardized servers and storage systems linked by high-speed interconnects, also known as clusters. Clustering enables significant improvements in performance, reliability, scalability, cost and power savings. The need for better utilization of floor space and power consumption has driven the adoption of compact form factor (size and shape) blade servers.

	•	Transition to multiple and multi-core processors in servers. In order to increase processing capabilities, processor vendors have integrated multiple computing cores into a single processor device. In addition, server original equipment manufacturers, or OEMs, are incorporating several multi-core processors into a single server. While this significantly increases the computing capabilities of an individual server, the total performance of a cluster of these servers is impacted by the total input/output, or I/O, bandwidth. Inadequate


		cluster I/O bandwidth results in processor underutilization, thereby reducing the overall capability and performance of the cluster.


	•	Data center infrastructure consolidation. IT managers are increasingly faced with the need to optimize total cost of ownership associated with the data centers they manage. As the demand for I/O to servers increases, so does the need for a unified I/O interconnect. In the past the solution was to add more I/O adapters and cables to each server, which resulted in increased costs, power consumption and management complexity. This has led to a widespread trend of consolidating network infrastructures to reduce costs and generate a higher return on investments.

	•	Increasing deployment of virtualized computing resources. Enterprises are turning to virtualization software, which allows multiple applications to run on a single server, thereby improving resource utilization and requiring increased I/O bandwidth in the EDC.

	•	Cloud computing. Cloud computing is a convergence of two interdependent IT trends — IT efficiency (converting IT costs from capital expenses to operating expenses) and business agility. The recent emergence of massive network bandwidth and virtualization technologies has enabled this transformation to a new services-oriented infrastructure. Cloud computing enables IT organizations to increase their hardware utilization and to scale up to massive capacities in an instant without having to invest in new infrastructure or license new software. With increased I/O bandwidth and lower latency, cloud providers can perform system provisioning, workload migrations and support multiple users’ requests faster and in the most efficient way.

	•	Increasing deployments of mission-critical, latency sensitive applications. There is an increasing number of applications that require extremely fast response times in order to deliver an optimal result or user experience. Reducing latency, the absolute time it takes for information to be sent from one resource to another over a high-performance interconnect, is critical to enhancing application performance in clustered environments. Some examples of applications that benefit from low-latency interconnect include financial trading, clustered databases and parallel processing solutions used in HPC.

	•	Virtual product design. A significant reduction in cost and turn-around time of product design can be accomplished by carrying out the design activities using simulation and optimization tools and reducing the number of prototypes and physical testing. To accomplish this, a detailed representation of the product’s physical properties, high capability simulations software tools and an intensive compute environment are required. Such environments mandate high-speed networking to become effective and carry the compute intensive simulations.

	•	Green computing. With the growth in IT capacity, data centers have become major consumers of electrical energy. Furthermore, data center networks have increased in size and managing a growingmulti-infrastructure has become a daunting task. Enterprise data centers currently use three different networks — Storage Area Networks using Fibre Channel transport for storage access, Local Area Network using Ethernet transport for standard network access and System Area Networks using InfiniBand transport for inter-process communication and high-performance clustering. In order to reduce energy, real estate, management and infrastructure costs of modern data centers, a new field of data center architecture was defined — the green data center. The new architecture leverages from I/O virtualization and consolidation to enable green, simple-managed, highly-utilized modern data centers. The ability to consolidate data center I/O mandates the use of high-throughput networks to deliver the needed bandwidth equal or greater than the sum of the separate networks.

Challenges Faced by High-Performance Interconnect

The trends described above indicate that high-performance interconnect solutions will play an increasingly important role in IT infrastructures and will drive strong growth in unit demand. Performance requirements for interconnect solutions, however, continue to evolve and lead to high demand for solutions that are capable of resolving the following challenges to facilitate broad adoption:


	•	Performance limitations. In clustered computing, cloud computing and storage environments, high bandwidth and low latency are key requirements to capture the full performance capabilities of a cluster.


		With the usage of multiple multi-core processors in server, storage and embedded systems, I/O bandwidth has not been able to keep pace with processor advances, creating performance bottlenecks. Fast data access has become a critical requirement to accommodate microprocessors’ increased compute power. In addition, interconnect latency has become a limiting factor in a cluster’s overall performance.


	•	Increasing complexity. The increasing usage of clustered servers and storage systems as a critical IT tool has led to an increase in complexity of interconnect configurations. The number of configurations and connections have also proliferated in EDCs, making them increasingly complicated to manage and expensive to operate. Additionally, managing multiple software applications utilizing disparate interconnect infrastructures has become increasingly complex.

	•	Interconnect inefficiency. The deployment of clustered computing and storage has created additional interconnect implementation challenges. As additional computing and storage systems, or nodes, are added to a cluster, the interconnect must be able to scale in order to provide the expected increase in cluster performance. Additionally, government attention on data center energy efficiency is causing IT managers to look for ways to adopt more energy-efficient implementations.

	•	Limited reliability and stability of connections. Most interconnect solutions are not designed to provide reliable connections when utilized in a large clustered environment, which can cause data transmission interruption. As more applications in EDCs share the same interconnect, advanced traffic management and application partitioning become necessary to maintain stability and reduce system down time. Such capabilities are not offered by most interconnect solutions.

	•	Poor price/performance economics. In order to provide the required system bandwidth and efficiency, most high-performance interconnects are implemented with complex, multi-chip semiconductor solutions. These implementations have traditionally been extremely expensive.

In addition to InfiniBand, proprietary and other standards-based, high-performance interconnect solutions, including Fibre Channel and Ethernet, are currently used in EDC, HPC and embedded markets. Performance and usage requirements, however, continue to evolve and are now challenging the capabilities of these interconnect solutions:


	•	Proprietary interconnect solutions have been designed for use in supercomputer applications by supporting low latency and increased reliability. These solutions are only supported by a single vendor for product and software support, and there is no standard organization maintaining and facilitating improvements and changes to the technology. The number of supercomputers that use proprietary interconnect solutions has been declining largely due to the availability of industry standards-based interconnects that offer superior price/performance, a lack of compatible storage systems, and the required use of proprietary software solutions.

	•	Fibre Channel is an industry standard interconnect solution limited to storage applications. The majority of Fibre Channel deployments support 2, 4 and 8Gb/s. Fibre Channel lacks a standard software interface, does not provide server cluster capabilities and remains more expensive relative to other standards-based interconnects. There have been industry efforts to support the Fibre Channel data transmission protocol over interconnect technologies including Ethernet (Fibre Channel over Ethernet) and InfiniBand (Fibre Channel over InfiniBand).

	•	Ethernet is an industry-standard interconnect solution that was initially designed to enable basic connectivity between a local area network of computers or over a wide area network, where latency, connection reliability and performance limitations due to communication processing are non-critical. While Ethernet has a broad installed base at 1Gb/s and lower data rates, its overall efficiency, scalability and reliability have been less optimal than certain alternative interconnect solutions in high-performance computing, storage and communication applications. An increase to 10Gb/s, a significant reduction in application latency and more efficient software solutions have improved Ethernet’s capabilities to address specific high-performance applications that do not demand the highest scalability. There are also ongoing efforts to standardize additional features within the Ethernet specification to improve its reliability and scalability in EDCs. These


		enhancements are in the definition and standardization process as part of the IEEE 802.1 Working Group and are generally referred to as Data Center Bridging.

In the HPC, EDC and embedded markets, the predominant interconnects today are 1Gb/s Ethernet and 4Gb/s Fibre Channel. Based on our knowledge of the industry, we believe there is significant demand for interconnect products that provide higher bandwidth and better overall performance in these markets.

Overview of the InfiniBand Standard

InfiniBand is an industry standard, high-performance interconnect architecture that effectively addresses the challenges faced by the IT industry by enabling cost-effective, high-speed data communications. We believe that InfiniBand has significant advantages compared to alternative interconnect technologies. InfiniBand defines specifications for designing host channel adapters, or HCAs, that fit into standard,off-the-shelf servers and storage systems, and switch solutions that connect all the systems together. The physical connection of multiple HCAs and switches is commonly known as an InfiniBand fabric.

The InfiniBand standard was developed under the auspices of the IBTA, which was founded in 1999 and is composed of leading IT vendors and hardware and software solution providers including Mellanox, Fujitsu, Hitachi, IBM, Intel, LSI Corporation, NEC, QLogic Corporation, Sun Microsystems and Voltaire. The IBTA tests and certifies vendor products and solutions for interoperability and compliance. Our products meet the specifications of the InfiniBand standard and have been tested and certified by the IBTA.

Advantages of InfiniBand

We believe that InfiniBand-based solutions have advantages compared to solutions based on alternative interconnect architectures. InfiniBand addresses the significant challenges within IT infrastructures created by more demanding requirements of the high-performance interconnect market. More specifically, we believe that InfiniBand has the following advantages:


	•	Superior performance. In comparison to other interconnect technologies that were architected to have a heavy reliance on communication processing, InfiniBand was designed for implementation in an IC that relieves the central processing unit, or CPU, of communication processing functions. InfiniBand is able to provide superior bandwidth and latency relative to other existing interconnect technologies and has maintained this advantage with each successive generation of products. For example, our current InfiniBand adapters provide bandwidth up to 40Gb/s, and our current switch ICs support bandwidth up to 120Gb/s, which is significantly higher than the 10Gb/s or less supported by competing technologies. The InfiniBand specification supports the design of interconnect products with up to 120Gb/s bandwidth, which is the highest performance industry-standard interconnect specification. In addition, InfiniBand fully leverages the I/O capabilities of PCI Express, a high-speed system bus interface standard.

The following table provides a bandwidth comparison of the various high performance interconnect solutions.


	Proprietary	Fibre Channel	Ethernet	InfiniBand

Supported bandwidth of available solutions	2Gb/s —10Gb/s	2Gb/s —8Gb/s	1Gb/s —10Gb/s	10Gb/s — 40Gb/s server-to-server 10Gb/s —120Gb/s switch-to-switch

Performance in terms of latency varies depending on system configurations and applications. According to independent benchmark reports, latency of InfiniBand solutions was less than half of that of tested 10Gb/s Ethernet and proprietary solutions. Fibre Channel, which is used only as a storage interconnect, is typically not benchmarked on latency performance. HPC typically demands low latency interconnect solutions. In addition, there are increasing numbers of latency-sensitive applications in the EDC and embedded markets, and, therefore, there is a trend towards using industry-standard InfiniBand and 10Gb/s Ethernet solutions that deliver lower latency than Gigabit Ethernet, which is predominantly used today.


	•	Reduced complexity. While other interconnects require use of individual cables to connect servers, storage and communications infrastructure equipment, InfiniBand allows for the consolidation of multiple I/Os on a


		single cable or backplane interconnect, which is critical for blade servers and embedded systems. InfiniBand also consolidates the transmission of clustering, communications and storage and management data types over a single connection.


	•	Highest interconnect efficiency. InfiniBand was developed to provide efficient scalability of multiple systems. InfiniBand provides communication processing functions in hardware, relieving the CPU of this task, and enables the full resource utilization of each node added to the cluster.

	•	Reliable and stable connections. InfiniBand is the only industry standard high-performance interconnect solution which provides reliableend-to-end data connections. In addition, InfiniBand facilitates the deployment of virtualization solutions, which allow multiple applications to run on the same interconnect with dedicated application partitions. As a result, multiple applications run concurrently over stable connections, thereby minimizing down time.

	•	Superior price/performance economics. In addition to providing superior performance and capabilities, standards-based InfiniBand solutions are generally available at a lower cost than other high-performance interconnects.

Our InfiniBand Solution

We provide comprehensive solutions based on InfiniBand, including HCA, switch and gateway ICs, adapter cards, switch and gateway systems and software. InfiniBand enables us to provide products that we believe offer superior performance and meet the needs of the most demanding applications, while also offering significant improvements in total cost of ownership compared to alternative interconnect technologies. For example, our current InfiniBand HCAs provide bandwidth up to 10Gbs (Single Data Rate or SDR), 20Gb/s (Double Data Rate or DDR) and 40Gb/s (Quad Data Rate or QDR) and our switch ICs provide bandwidth up to 120Gb/s per interface, which is significantly higher than the 10Gb/s or less supported by competing technologies. As part of our comprehensive solution, we perform validation and interoperability testing from the physical interface to the applications software. Our expertise in performing validation and testing reduces time to market for our customers and improves the reliability of the fabric solution.

Data provided in the most recent list of the World’s Fastest Supercomputers published by TOP500.org in November 2009 illustrates the benefits of our solutions. TOP500.org is an independent organization that was founded in 1993 to provide a reliable basis for reporting trends in high-performance computing by publishing a list of the most powerful computers twice a year. The number of listed InfiniBand-based supercomputers has grown from 142 as of November 2008 to 182 as of November 2009, which represents a 28% increase. InfiniBand-based clusters represented five of the top 10 and 63% of the top 100. The November 2009 TOP500 list also illustrates that InfiniBand interconnects have continued to replace proprietary interconnects in supercomputers. Proprietary interconnects have declined significantly since the November 2007 list, and represent less than 2% of the latest list. We believe that the majority of these InfiniBand-based supercomputers incorporate our HCA products and that all of them use our switch silicon products. Additionally, we believe the current cluster implementations that incorporate both our HCA and switch silicon products in the November 2009 TOP500 list of the World’s Fastest Supercomputers compare favorably to clusters based on other interconnect technologies.

Our Ethernet Solution

Advances in server virtualization, network storage and compute clusters have driven the need for faster network throughput to address application latency and availability problems in the Enterprise. To service this need, we provide competitive, high bandwidth 10 and 40 Gigabit Ethernet adapters for use in Enterprise Data Centers, High-Performance Computing and Embedded environments. These adapters remove I/O bottlenecks in mainstream servers that are limiting application performance and support hardware-based I/O virtualization, providing dedicated adapter resources and guaranteed isolation and protection for virtual machines within the server.

VPI: Providing Connectivity to InfiniBand and Ethernet

In addition to supporting InfiniBand, our latest generation adapter products also support the industry standard Ethernet interconnect specification at 1Gb/s, 10Gb/s and 40Gb/s. In developing this dual interconnect support, we created VPI. VPI enables us to offer products that concurrently support both Ethernet and InfiniBand with network ports having the ability to auto sense the type of switch to which it is connected and then take on the characteristics of that fabric. In addition, these products extend certain InfiniBand advantages to Ethernet fabrics, such as reduced complexity and superior price/performance, by utilizing existing, field-proven InfiniBand software solutions.

Our Strengths

We apply our strengths to enhance our position as a leading supplier of semiconductor-based, high-performance interconnect products. We consider our key strengths to include the following:


	•	We have expertise in developing high-performance interconnect solutions. We were founded by a team with an extensive background in designing and marketing semiconductor solutions. Since our founding, we have been focused on high-performance interconnect and have successfully launched several generations of InfiniBand products in addition to launching our first Ethernet products. We believe we have developed strong competencies in integrating mixed-signal design and developing complex ICs. We have used these competencies along with our knowledge of InfiniBand to design our innovative, next generation, high-performance products that also support the Ethernet interconnect standard. We also consider our software development capability as a key strength, and we believe that our software allows us to offer complete solutions. We have developed a significant portfolio of intellectual property, or IP, and have 27 issued patents. We believe our experience, competencies and IP will enable us to remain a leading supplier of high-performance interconnect solutions.

	•	We believe we are the leading merchant supplier of InfiniBand ICs with a multi-year competitive advantage. We have gained in-depth knowledge of the InfiniBand standard through active participation in its development. We were first to market with InfiniBand products (in 2001) and InfiniBand products that support the standard PCI Express interface (in 2004) and PCI Express 2.0 interface (in 2007). We have sustained our leadership position through the introduction of several generations of products. Because of our market leadership, vendors have developed and continue to optimize their software products based on our semiconductor solutions. We believe that this places us in an advantageous position to benefit from continuing market adoption of our products.

	•	We have a comprehensive set of technical capabilities to deliver innovative and reliable products. In addition to designing our ICs, we design standard adapter card products and custom adapter card and switch products, providing us a deep understanding of the associated circuitry and component characteristics. We believe this knowledge enables us to develop solutions that are innovative and can be efficiently implemented in target applications. We have devoted significant resources to develop our in-house test development capabilities, which enables us to rapidly finalize our mass production test programs, thus reducing time to market. We have synchronized our test platform with our outsourced testing provider and are able to conduct quality control tests with minimal disruption. We believe that because our capabilities extend from product definition, through IC design, and ultimately management of our high-volume manufacturing partners, we have better control over our production cycle and are able to improve the quality, availability and reliability of our products.

	•	We have extensive relationships with our key OEM customers and many end users. Since our inception we have worked closely with major OEMs, including leading server, storage, communications infrastructure equipment and embedded systems vendors, to develop products that accelerate market adoption of InfiniBand. During this process we have obtained valuable insight into the challenges and objectives of our customers, and gained visibility into their product development plans. We also have established end-user relationships with influential IT executives who allow us access to firsthand information about evolving EDC, HPC and embedded market trends. We believe that our OEM customer and end-user relationships allow us to stay at the forefront of developments and improve our ability to provide compelling solutions to address their needs.

Our Strategy

Our goal is to be the leading supplier ofend-to-end connectivity solutions for servers and storage that optimize data center performance for computing, storage and communications applications. To accomplish this goal, we intend to:


	•	Continue to develop leading, high-performance interconnect products. We will continue to expand our technical expertise and customer relationships to develop leading interconnect products. We are focused on extending our leadership position in high-performance interconnect technology and pursuing a product development plan that addresses emerging customer and end-user demands and industry standards. In order to expand our market opportunity, we have added products that are compatible with the Ethernet interconnect standard in addition to InfiniBand. These products will allow our customers to capture certain advantages of InfiniBand while providing connectivity to Ethernet-based infrastructure equipment. Our unified software strategy is to use a single software stack to support connectivity to InfiniBand and Ethernet with the same VPI enabled hardware adapter device.

	•	Facilitate and increase the continued adoption of InfiniBand. We will facilitate and increase the continued adoption of InfiniBand in the high-performance interconnect marketplace by expanding our partnerships with key vendors that drive high-performance interconnect adoption, such as suppliers of processors, operating systems and other associated software. In conjunction with our OEM customers, we will expand our efforts to promote the benefits of InfiniBand and VPI directly to end users to increase demand for high performance interconnect solutions.

	•	Expand our presence with existing server OEM customers. We believe the leading server vendors are influential drivers of high-performance interconnect technologies to end users. We plan to continue working with and expanding our relationships with server OEMs to increase our presence in their current and future product platforms.

	•	Broaden our customer base with storage, communications infrastructure and embedded systems OEMs. We believe there is a significant opportunity to expand our global customer base with storage, communications infrastructure and embedded systems OEMs. In storage solutions specifically, we believe our products are well suited to replace existing technologies such as Fibre Channel. We believe our products are the basis of superior interconnect fabrics for unifying disparate storage interconnects, including back-end, clustering and front-end connections, primarily due to their ability to be a unified fabric and superior price/performance economics.

	•	Leverage our fabless business model to deliver strong financial performance. We intend to continue operating as a fabless semiconductor company and consider outsourced manufacturing of our ICs and adapter cards to be a key element of our strategy. Our fabless business model offers flexibility to meet market demand and allows us to focus on delivering innovative solutions to our customers. We plan to continue to leverage the flexibility and efficiency offered by our business.

Our Products

We provide complete solutions which are based on and meet the specifications of the InfiniBand standard in addition to products that also support the Ethernet standard. Our InfiniBand products include adapter ICs and cards (InfiniHost^® product family) and switch ICs (InfiniScale^® product family) and systems, gateway ICs (BridgeX^® product family) and gateway systems. Our latest 4th and 5th generation adapters and cards (ConnectX^® and ConnectX-2 product families) also support the Ethernet interconnect standard in addition to InfiniBand. Our gateway devices support bridging capabilities from InfiniBand to Ethernet and Fibre Channel, and from Ethernet to Fibre Channel.

We have registered “Mellanox,” “BridgeX,” “ConnectX,” “InfiniBridge,” “InfiniHost,” “InfiniPCI,” “InfiniRISC” and “InfiniScale” as trademarks in the United States. We have a trademark application pending to register “ “FabricIT” and “CORE-Direct.”

We provide adapters to server, storage, communications infrastructure and embedded systems OEMs as ICs or standard card form factors with PCI-X or PCI Express interfaces. Adapter ICs or cards are incorporated into OEM server and storage systems to provide InfiniBandand/or Ethernet connectivity. All of our adapter products interoperate with standard programming interfaces and are compatible with previous generations, providing broad industry support. We also support server operating systems including Linux, Windows, AIX, HPUX, Solaris and VxWorks.

We also provide our InfiniBand switch ICs to server, storage, communications infrastructure and embedded systems OEMs to create switching equipment that is at the core of InfiniBand fabrics. To deploy an InfiniBand fabric, any number of server or storage systems that contain an HCA can be connected to an InfiniBand-based communications infrastructure system such as an InfiniBand switch. Our 4th generation switch IC (InfiniScale IV) supports up to 120Gb/s InfiniBand throughput. We have also introduced our 40Gb/s InfiniBand switch systems that include 36-port, 108-port, 216-portm, 324-port and 648-port.

The figure below illustrates the components of servers and storage equipment clustered with a high-performance interconnect and how our products are incorporated into the total solution.

Our products generally vary by the number and performance of InfiniBandand/or Ethernet ports supported.

We also offer custom products that incorporate our ICs to select server and storage OEMs that meet their special system requirements. Through these custom product engagements we gain insight into the OEMs’ technologies and product strategies.

We also provide our OEM customers software and tools that facilitate the use and management of our products. Developed in conjunction with the OFA, our Linux- and Windows-based software enables applications to efficiently utilize the features of the interconnect. We have expertise in optimizing the performance of software that spans the entire range of upper layer protocols down through the lower level drivers that interface to our products. We provide a suite of software tools and a comprehensive management software solution, FabricIT, for managing, optimizing, testing and verifying the operation of InfiniBand switch fabrics. We also provide gateway management software, FabricIT BridgeX Manager, which runs on top of our BridgeX gateway systems to manage I/O consolidation from an InfiniBand network to Ethernet and Fibre Channel for cluster, cloud and virtual environments.

We provide an extensive selection of passive and optical cabling and modules to enable InfiniBand and Ethernet connectivity.

Technology

We have technological core competencies in the design of high-performance interconnect ICs that enable us to provide a high level of integration, efficiency, flexibility and performance for our adapter and switch ICs. Our products integrate multiple complex components onto a single IC, including high-performance mixed-signal design, specialized communication processing functions and advanced interfaces.

High-performance mixed-signal design

One of the key technology differentiators of our ICs is our mixed-signal data transmission SerDes technology. SerDes I/O directly drives the interconnect interface, which provides signaling and transmission of data over copper interconnects and cables or fiber optic interfaces for longer distance connections. We are the only company that has shipped field-proven integrated controller ICs that operate with a 5Gb/s SerDes over a ten meter InfiniBand copper cable (up to 60Gb/s connections with 12 SerDes working in parallel on our switch IC). Additionally, we are able to integrate several of these high-performance SerDes onto a single, low-power IC, enabling us to provide the highest bandwidth, merchant switch ICs based on an industry-standard specification. We have developed a 10Gb/s SerDes I/O that is used in our 4th generation ConnectX adapter that supports both InfiniBand and Ethernet, as well as our 4th generation InfiniScale IV switch IC that supports InfiniBand. Our 10Gb/s SerDes enables our ConnectX adapters to support 40Gb/s bandwidth (4 10Gb/s SerDes operating in parallel) in addition to providing a direct 10Gb/s connection to standard XFP and SFP+ fiber modules to provide long range Ethernet connectivity without the requirement of additional components, which saves power, cost and board space. In addition, our 10Gb/s SerDes supports 40Gb/s (4 10Gb/s SerDes operating in parallel) as well as 120Gb/s (12 10Gb/s SerDes operating in parallel) port bandwidth on our InfiniScale IV switch IC.

Specialized communication processing and switching functions

We also specialize in high-performance, low-latency design architectures that incorporate significant memory and logic areas requiring proficient synthesis and verification. Our adapter ICs are specifically designed to perform communication processing, effectively offloading this very intensive task from server and storage processors in a cost-effective manner. Our switch ICs are specifically designed to switch cluster interconnect data transmissions from one port to another with high bandwidth and low latency, and we have developed a packet switching engine and non-blocking crossbar switch fabric to address this.

We have developed a custom embedded Reduced Instruction Set Computer processor called InfiniRISC^{^®} that specializes in offloading network processing from the host server or storage system and adds flexibility, product differentiation and customization. We integrate a different number of these processors in a device depending on the application and feature targets of the particular product. Integration of these processors also shortens development cycles as additional features can be added by providing new programming packages after the ICs are manufactured, and even after they are deployed in the field.

Advanced interfaces

In addition to InfiniBand and Ethernet interfaces, we also provide other industry-standard, high-performance advanced interfaces such as PCI Express and PCI Express 2.0 which also utilize our mixed-signal 2.5Gb/s and5Gb/s SerDes I/O technology. PCI Express is a high-speedchip-to-chip interface which provides a high-performance interface between the adapter and processor in server and storage systems. PCI Express and our high-performance interconnect interfaces are complementary technologies that facilitate optimal bandwidth for data transmissions along the entire connection starting from a processor of one system in the cluster to another processor in a different system. We were among the first to market with an IC solution that integrates the PCI Express interface (in 2004) and PCI Express 2.0 interface (in 2007), and we believe this provides an example of the technical proficiency of our development team.

We currently anticipate that several of these evaluations will result in increased orders for our products as they move into the production stage.

Sales and Marketing

We sell our products worldwide through multiple channels, including our direct sales force, our network of domestic and international sales representatives and independent distributors. We have strategically located sales personnel in the United States, Europe, China, India and Taiwan. Our sales directors focus their efforts on leading OEMs and target key decision makers. We are also in frequent communication with our customers’ and partners’ sales organizations to jointly promote our products and partner solutions into end-user markets. We have expanded our business development team which engages directly with end users promoting the benefits of our products which we believe creates additional demand for our customers’ products that incorporate our products.

Our sales support organization is responsible for supporting our sales channels and managing the logistics from order entry to delivery of products to our customers. In addition, our sales support organization is responsible for customer and revenue forecasts, customer agreements and program management for our large, multi-national customers. Customers within the North America are supported by our staff in California and customers outside of the North America are supported by our staff in Israel.

To accelerate design and qualification of our products into our OEM customers’ systems, and ultimately the deployment of our technology by our customers to end users, we have a field applications engineering, or FAE, team and an internal support engineering team that provide direct technical support. In certain situations, our OEM customers will also utilize our expertise to support their end-user customers jointly. Our technical support personnel have expertise in hardware and software, and have access to our development team to ensure proper service and support for our OEM customers. Our FAE team provides OEM customers with design and review capabilities of their systems in addition to technical training on the technology we have implemented in our products.

Our marketing team is responsible for product strategy and management, future product plans and positioning, pricing, product introductions and transitions, competitive analysis, marketing communications and raising the overall visibility of our company. The marketing team works closely with both the sales and research and development organizations to properly align development programs and product launches with market demands.

Our marketing team leads our efforts to promote our interconnect technology and our products to the entire industry by:


	•	assuming leadership roles within IBTA, OFA, Blade.org and other industry trade organizations;


	•	participating in trade shows, press and analyst briefings, conference presentations and seminars for end-user education; and

	•	building and maintaining active partnerships with industry leaders whose products are important in driving InfiniBand and Ethernet adoption, including vendors of processors, operating systems and software applications.

Research and Development

Our research and development team is composed of experienced semiconductor designers, software developers and system designers. Our semiconductor design team has extensive experience in all phases of complex, high-volume design, including product definition and architecture specification, hardware code development, mixed-signal and analog design and verification. Our software team has extensive experience in development, verification, interoperability testing and performance optimization of software for use in computing and storage applications. Our systems design team has extensive experience in all phases of high-volume adapter card and custom switch designs including product definition and architectural specification, product design, design verification and transfer to production.

We design our products with careful attention to quality, reliability, cost and performance requirements. We utilize a methodology called Customer Owned Tooling, or COT, where we control and manage a significant portion of timing and layout design and verification in-house, before sending the semiconductor design to our third-party manufacturer. Although COT requires a significant up-front investment in tools and personnel, it provides us with greater control over the quality and reliability of our IC products as opposed to relying on third-party verification services, as well as better time to market.

We choose first tier technology vendors for our design tools and continue to maintain long-term relationships with our vendors to ensure timely support and updates. We also select a mainstream silicon manufacturing process only after it has proven its production worthiness. We verify that actual silicon characterization and performance measurements strongly correlate to models that were used to simulate the device while in design, and that our products meet frequency, power and thermal targets with good margins. Furthermore, we insertDesign-for-Test circuitry into our IC products which increases product quality, provides expanded debugging capabilities and ultimately enhances system-level testing and characterization capabilities once the device is integrated into our customers’ products.

Frequent interaction between our silicon, software and systems design teams gives us a comprehensive view of the requirements necessary to deliver quality, high-performance products to our OEM customers. Our research and development expense was $42.2 million in 2009, $39.5 million in 2008 and $24.6 million in 2007.

Manufacturing

We depend on third-party vendors to manufacture, package and production test our products as we do not own or operate a semiconductor fabrication, packaging or production testing facility. By outsourcing manufacturing, we are able to avoid the high cost associated with owning and operating our own facilities. This allows us to focus our efforts on the design and marketing of our products.

Manufacturing and Testing. We use Taiwan Semiconductor Manufacturing Company, or TSMC, to manufacture and Advanced Semiconductor Engineering, or ASE, to assemble, package and production test our IC products. We use Flextronics to manufacture our standard and custom adapter card products and switch systems. We maintain close relationships with our suppliers, which improves the efficiency of our supply chain. We focus on mainstream processes, materials, packaging and testing platforms, and have a continuous technology assessment program in place to choose the appropriate technologies to use for future products. We provide all of our suppliers a12-month rolling forecast, and receive their confirmation that they are able to accommodate our needs on a monthly basis. We have access to on-line production reports that provideup-to-date status information of our products as they flow through the manufacturing process. On a quarterly basis, we review lead-time, yield enhancements and pricing with all of our suppliers to obtain the optimal cost for our products.

Quality Assurance. We maintain an ongoing review of product manufacturing and testing processes. Our IC products are subjected to extensive testing to assess whether their performance exceeds the design specifications. We own an in-house Teradyne Tiger IC tester which provides us with immediate test data and the ability to generate characterization reports that are made available to our customers. Our adapter cards and custom switch system products are subject to similar levels of testing and characterization, and are additionally tested for regulatory agency certifications such as Safety and EMC (radiation test) which are made available to our customers. We only use components on these products that are qualified to be on our approved vendor list.

Requirements Associated with the OCS. Israeli law requires that we manufacture our products developed with government grants in Israel unless we otherwise obtain approval from the Office of the Chief Scientist of Israel’s Ministry of Industry Trade and Labor, or the OCS. This approval, if provided, is generally conditioned on an increase in the total amount to be repaid to the OCS, ranging from 120% to 300% of the amount of funds granted. The specific increase would depend on the extent of the manufacturing to be conducted outside of Israel. The restriction on manufacturing outside of Israel does not apply to the extent that we disclosed our plans to manufacture outside of Israel when we filed the application for funding (and provided the application was approved based on the information disclosed in the application). We have indicated our intent to manufacture outside of Israel on some of our grant applications, and the OCS has approved the manufacture of our IC products outside of Israel, subject to our undertaking to pay the OCS royalties from the sales of these products up to 120% of the amount of OCS funds granted. The manufacturing of our IC products outside of Israel, including those products manufactured by TSMC and ASE, is in compliance with the terms of our grant applications and applicable provisions of Israeli law. Under applicable Israeli law, Israeli government consent is required to transfer technologies developed under projects funded by the government to third parties outside of Israel. Transfer of OCS-funded technologies outside of Israel is permitted with the approval of the OCS and in accordance with the restrictions and payment obligations set forth under Israeli law. Israeli law further specifies that both the transfer of know-how as well as the transfer of IP rights in such know-how are subject to the same restrictions. These restrictions do not apply to exports from Israel or the sale of products developed with these technologies.

Employees

As of December 31, 2009, we had 329 full-time employees and 42 part-time employees located in the United States and Israel including 261 in research and development, 54 in sales and marketing, 28 in general and administrative and 28 in operations. Of our 329 full-time employees, 265 are located in Israel.

Certain provisions of the collective bargaining agreements between the Histadrut (General Federation of Labor in Israel) and the Coordination Bureau of Economic Organizations (including the Industrialists’ Associations) are applicable to our employees in Israel by order of the Israeli Ministry of Labor. These provisions primarily concern the length of the workday, minimum daily wages for professional workers, pension fund benefits for all employees, insurance for work-related accidents, procedures for dismissing employees, determination of severance pay and other conditions of employment. We generally provide our employees with benefits and working conditions above the required minimums.

We have never experienced any employment-related work stoppages and believe our relationship with our employees is good.

Intellectual Property

One of the key values and drivers for future growth of our high-performance interconnect IC products is the IP we develop and use to improve them. We believe that the main value proposition of our high-performance interconnect products and success of our future growth will depend on our ability to protect our IP. We rely on a combination of patent, copyright, trademark, mask work, trade secret and other IP laws, both in the United States and internationally, as well as confidentiality, non-disclosure and inventions assignment agreements with our employees, customers, partners, suppliers and consultants to protect and otherwise seek to control access to, and distribution of, our proprietary information and processes. In addition, we have developed technical knowledge, which, although not patented, we consider to be significant in enabling us to compete. The proprietary nature of

such knowledge, however, may be difficult to protect and we may be exposed to competitors who independently develop the same or similar technology or gain access to our knowledge.

The semiconductor industry is characterized by frequent claims of infringement and litigation regarding patent and other IP rights. We, like other companies in the semiconductor industry, believe it is important to aggressively protect and pursue our IP rights. Accordingly, to protect our rights, we may file suit against parties whom we believe are infringing or misappropriating our IP rights. These measures may not be adequate to protect our technology from third party infringement or misappropriation, and may be costly and may divert management’s attention away fromday-to-day operations. We may not prevail in these lawsuits. If any party infringes or misappropriates our IP rights, this infringement or misappropriation could materially adversely affect our business and competitive position.

As of December 31, 2009, we had 19 issued patents and 30 patent applications pending in the United States, five issued patents in Taiwan and three issued patents and two applications pending in Israel, each of which covers aspects of the technology in our products. The term of any issued patent in the United States is 20 years from its filing date and if our applications are pending for a long time period, we may have a correspondingly shorter term for any patent that may be issued. Our present and future patents may provide only limited protection for our technology and may not be sufficient to provide competitive advantages to us. Furthermore, we cannot assure you that any patents will be issued to us as a result of our patent applications.

The risks associated with patents and intellectual property are more fully discussed under the section entitled “Risk Factors” under Item 1A of this report.

Competition

The markets in which we compete are highly competitive and are characterized by rapid technological change, evolving industry standards and new demands on features and performance of interconnect solutions. We compete primarily on the basis of:


	•	price/performance;

	•	time to market;

	•	features and capabilities;

	•	wide availability of complementary software solutions;

	•	reliability;

	•	power consumption;

	•	customer support; and

	•	product roadmap.

We believe that we compete favorably with respect to each of these criteria. Many of our current and potential competitors, however, have longer operating histories, significantly greater resources, greater economies of scale, stronger name recognition and a larger base of customers than we do. This may allow them to respond more quickly than we are able to respond to new or emerging technologies or changes in customer requirements. In addition, these competitors may have greater credibility with our existing and potential customers. They may be able to introduce new technologies or devote greater resources to the development, marketing and sales of their products than we can. Furthermore, in the event of a manufacturing capacity shortage, these competitors may be able to manufacture products when we are unable.

We compete with other providers of semiconductor-based high performance interconnect products based on InfiniBand, Ethernet, Fibre Channel and proprietary technologies. With respect to InfiniBand products, we compete with QLogic Corporation. In EDCs, products based on the InfiniBand standard primarily compete with two different industry-standard interconnect technologies, namely Ethernet and Fibre Channel. For Ethernet technology, the leading IC vendors include Intel and Broadcom Corporation. The leading IC vendors that provide Ethernet and Fibre Channel products to the market include Emulex Corporation and QLogic Corporation. In HPC, products

based on the InfiniBand standard primarily compete with the industry-standard Ethernet and Fibre Channel interconnect technologies. In embedded markets, we typically compete with interconnect technologies that are developed in-house by system OEM vendors and created for specific applications.

ITEM 1A —	*RISK FACTORS*

Investing in our ordinary shares involves a high degree of risk. You should carefully consider the following risk factors, in addition to the other information set forth in this report, before purchasing our ordinary shares. Each of these risk factors could harm our business, financial condition or operating results, as well as decrease the value of an investment in our ordinary shares.

Risks Related to Our Business

The global recession and the downturn in the semiconductor industry may cause our revenues and profitability to decline.

The general worldwide economic condition has significantly deteriorated due to many factors including credit conditions and liquidity concerns resulting from the financial crisis affecting the banking system and financial markets, slower economic activity, decreased consumer confidence, reduced corporate profits and capital spending and adverse business conditions. Although conditions in the semiconductor market in which we participate have recently improved and general economic conditions have recently shown signs of improvement in the United States and certain other countries, if general global economic conditions do not improve or deteriorate further, it could

adversely affect the semiconductor market and be extremely difficult for us, our customers and our vendors to accurately forecast and plan future business activities, and it could cause U.S. and foreign businesses to reduce spending on our products and services, which would delay and lengthen sales cycles. Furthermore, during challenging economic times, our customers may face issues gaining timely access to sufficient credit, which could impair their ability to make timely payments. We cannot predict the timing, strength or duration of any economic slowdown or subsequent economic recovery, either worldwide, or in the semiconductor industry. If the economy does not improve or if it continues to deteriorate, our customers or potential customers could reduce or delay their purchases of our products, which would adversely impact our revenues and our ability to manage inventory levels, collect customer receivables and, ultimately, our profitability.

We do not expect to sustain our historical revenue growth rate, which may reduce our share price.

Our revenues increased by 73%, 28% and 8% in 2007, 2008 and 2009, respectively. Our revenues increased from $48.5 million to $84.1 million to $107.7 million to $116.0 million for the years ended December 31, 2006, 2007, 2008 and 2009, respectively. Our revenue growth rate has slowed during recent years and we may not be able to sustain this growth rate in future periods. You should not rely on the revenue growth of any prior quarterly or annual periods as an indication of our future performance. If we are unable to maintain adequate revenue growth, we may not have adequate resources to execute our business objectives and our share price may decline.

InfiniBand may not be adopted at the rate or extent that we anticipate, and adoption of InfiniBand is largely dependent on third-party vendors and end users.

While the usage of InfiniBand has increased since its first specifications were completed in October 2000, continued adoption of InfiniBand is dependent on continued collaboration and cooperation among information technology, or IT, vendors. In addition, the end users that purchase IT products and services from vendors must find InfiniBand to be a compelling solution to their IT system requirements. We cannot control third-party participation in the development of InfiniBand as an industry standard technology. We rely on server, storage, communications infrastructure equipment and embedded systems vendors to incorporate and deploy InfiniBand integrated circuits, or ICs, in their systems. InfiniBand may fail to effectively compete with other technologies, which may be adopted by vendors and their customers in place of InfiniBand. The adoption of InfiniBand is also impacted by the general replacement cycle of IT equipment by end users, which is dependent on factors unrelated to InfiniBand. These factors may reduce the rate at which InfiniBand is incorporated by our current server vendor customers and impede its adoption in the storage, communications infrastructure and embedded systems markets, which in turn would harm our ability to sell our InfiniBand products.

We have limited visibility into end-user demand for our products, which introduces uncertainty into our production forecasts and business planning and could negatively impact our financial results.

Our sales are made on the basis of purchase orders rather than long-term purchase commitments. In addition, our customers may defer purchase orders. We place orders with the manufacturers of our products according to our estimates of customer demand. This process requires us to make multiple demand forecast assumptions with respect to both our customers’ and end users’ demands. It is more difficult for us to accurately forecast end-user demand because we do not sell our products directly to end users. In addition, the majority of our adapter card business is conducted on a short order fulfillment basis, introducing more uncertainty into our forecasts. Because of the lead time associated with fabrication of our semiconductors, forecasts of demand for our products must be made in advance of customer orders. In addition, we base business decisions regarding our growth on our forecasts for customer demand. As we grow, anticipating customer demand may become increasingly difficult. If we overestimate customer demand, we may purchase products from our manufacturers that we may not be able to sell and may over-budget our operations. Conversely, if we underestimate customer demand or if sufficient manufacturing capacity were unavailable, we would forego revenue opportunities and could lose market share or damage our customer relationships.

We depend on a small number of customers for a significant portion of our sales, and the loss of any of these customers will adversely affect our revenues.

A small number of customers account for a significant portion of our revenues. In the year ended December 31, 2009, sales to Hewlett Packard accounted for 15% of our total revenues, sales to IBM accounted for 11% of our total revenues and sales to Supermicro Computer Inc. accounted for 10% of our total revenues. In the year ended December 31, 2008, sales to Hewlett-Packard accounted for 19% of our total revenues, sales to Sun Microsystems accounted for 17% of our total revenues, and sales to QLogic Corporation accounted for 11% of our total revenues. In the year ended December 31, 2007, sales to Hewlett-Packard accounted for 19% of our total revenues, sales to Voltaire accounted for 15% of our total revenues, and sales to Cisco Systems and QLogic Corporation each accounted for 11% of our total revenues. Because the majority of servers, storage, communications infrastructure equipment and embedded systems are sold by a relatively small number of vendors, we expect that we will continue to depend on a small number of customers to account for a significant percentage of our revenues for the foreseeable future. Our customers, including our most significant customers, are not obligated by long-term contracts to purchase our products and may cancel orders with limited potential penalties. If any of our large customers reduces or cancels its purchases from us for any reason, it could have an adverse effect on our revenues and results of operations.

We face intense competition and may not be able to compete effectively, which could reduce our market share, net revenues and profit margin.

The markets in which we operate are extremely competitive and are characterized by rapid technological change, continuously evolving customer requirements and declining average selling prices. We may not be able to compete successfully against current or potential competitors. With respect to InfiniBand products, we compete with QLogic Corporation, which introduced its latest generation 40Gb/s switch technology in the fourth quarter of 2009. With respect to 10Gb Ethernet products, we compete with Intel, Broadcom Corporation and QLogic Corporation. We also compete with providers of alternative technologies, including Ethernet, Fibre Channel and proprietary interconnects. The companies that provide IC products for these alternative technologies include Marvell Technology Group, Broadcom Corporation, Intel, Emulex Corporation, QLogic Corporation and Myricom.

Some of our customers are also integrated circuit and switch suppliers and already have similar expertise in-house. The process of licensing our technology to and support of such customers entails the transfer of technology that may enable them to become a source of competition to us, despite our efforts to protect our intellectual property rights. Further, each new design by a customer presents a competitive situation. In the past, we have lost design wins to divisions within our customers and this may occur again in the future. We cannot assure you that these customers will not continue to compete with us, that they will continue to be our customers or that they will continue to buy products from us at the same volumes. Competition could increase pressure on us to lower our prices and could negatively impact our profit margins.

Many of our current and potential competitors have longer operating histories, significantly greater resources, greater economies of scale, stronger name recognition and larger customer bases than we have. This may allow them to respond more quickly than we are able to respond to new or emerging technologies or changes in customer requirements. In addition, these competitors may have greater credibility with our existing and potential customers. If we do not compete successfully, our market share, revenues and profit margin may decline, and, as a result, our business may be adversely affected.

If we fail to develop new products or enhance our existing products to react to rapid technological change and market demands in a timely and cost-effective manner, our business will suffer.

We must develop new products or enhance our existing products with improved technologies to meet rapidly evolving customer requirements. We are currently engaged in the development process for next generation products, and we need to successfully design our next generation and other products for customers who continually require higher performance and functionality at lower costs. The development process for these advancements is lengthy and will require us to accurately anticipate technological innovations and market trends. Developing and

enhancing these products can be time-consuming, costly and complex. Our ability to fund product development and enhancements partially depends on our ability to generate revenues from our existing products.

There is a risk that these developments or enhancements, such as the migration of our next generation products from 90nm to 40nm to lower geometry process technologies, will be late, fail to meet customer or market specifications and will not be competitive with other products using alternative technologies that offer comparable performance and functionality. We may be unable to successfully develop additional next generation products, new products or product enhancements. Our next generation products or any new products or product enhancements may not be accepted in new or existing markets. Our business will suffer if we fail to continue to develop and introduce new products or product enhancements in a timely manner or on a cost-effective basis.

We rely on a limited number of subcontractors to manufacture, assemble, package and production test our products, and the failure of any of these third-party subcontractors to deliver products or otherwise perform as requested could damage our relationships with our customers, decrease our sales and limit our growth.

While we design and market our products and conduct test development in-house, we do not manufacture, assemble, package and production test our products, and we must rely on third-party subcontractors to perform these services. We currently rely on Taiwan Semiconductor Manufacturing Company, or TSMC, to produce our silicon wafers, and Flextronics International Ltd. to manufacture and production test our adapter cards and switches. We also rely on Advanced Semiconductor Engineering, or ASE, to assemble, package and production test our ICs. If these subcontractors do not provide us with high-quality products, services and production and production test capacity in a timely manner, or if one or more of these subcontractors terminates its relationship with us, we may be unable to obtain satisfactory replacements to fulfill customer orders on a timely basis, our relationships with our customers could suffer, our sales could decrease and our growth could be limited. In particular, there are significant challenges associated with moving our IC production from our existing manufacturer to another manufacturer with whom we do not have a pre-existing relationship.

We currently do not have long-term supply contracts with any of our third-party subcontractors. Therefore, they are not obligated to perform services or supply products to us for any specific period, in any specific quantities or at any specific price, except as may be provided in a particular purchase order. None of our third-party subcontractors has provided contractual assurances to us that adequate capacity will be available to us to meet future demand for our products. Our subcontractors may allocate capacity to the production of other companies’ products while reducing deliveries to us on short notice. Other customers that are larger and better financed than we are or that have long-term agreements with these subcontractors may cause these subcontractors to reallocate capacity to those customers, thereby decreasing the capacity available to us.

Other significant risks associated with relying on these third-party subcontractors include:


	•	reduced control over product cost, delivery schedules and product quality;

	•	potential price increases;

	•	inability to achieve sufficient production, increase production or test capacity and achieve acceptable yields on a timely basis;

	•	increased exposure to potential misappropriation of our intellectual property;

	•	shortages of materials used to manufacture products;

	•	capacity shortages;

	•	labor shortages or labor strikes;

	•	political instability in the regions where these subcontractors are located; and

	•	natural disasters impacting these subcontractors.

If we fail to carefully manage the use of “open source” software in our products, we may be required to license key portions of our products on a royalty-free basis or expose key parts of source code.

Certain of our software may be derived from “open source” software that is generally made available to the public by its authorsand/or other third parties. Such open source software is often made available to us under licenses, such as the GNU General Public License, which impose certain obligations on us in the event we were to distribute derivative works of the open source software. These obligations may require us to make source code for the derivative works available to the publicand/or license such derivative works under a particular type of license, rather than the forms of licenses customarily used to protect our intellectual property. In the event the copyright holder of any open source software were to successfully establish in court that we had not complied with the terms of a license for a particular work, we could be required to release the source code of that work to the publicand/or stop distribution of that work.

Our sales cycle can be lengthy, which could result in uncertainty and delays in generating revenues.

We have occasionally experienced a lengthy sales cycle for some of our products, due in part to the constantly evolving nature of the technologies on which our products are based. Some of our products must be custom designed to operate in our customers’ products, resulting in a lengthy process between the initial design stage and the ultimate sale. We also compete for design wins prior to selling products, which may increase the length of the sales process. We may experience a delay between the time we increase expenditures for research and development, sales and marketing efforts and inventory and the time we generate revenues, if any, from these expenditures. In addition, because we do not have long-term supply contracts with our customers and the majority of our sales are on a purchase order basis, we must repeat our sales process on a continual basis, including sales of new products to existing customers. As a result, our business could be harmed if a customer reduces or delays its orders.

The average selling prices of our products have decreased in the past and may do so in the future, which could harm our financial results.

The products we develop and sell are subject to declines in average selling prices. We have had to reduce our prices in the past and we may be required to reduce prices in the future. Reductions in our average selling prices to one customer could impact our average selling prices to other customers. This would cause our gross margin to decline. Our financial results will suffer if we are unable to offset any reductions in our average selling prices by increasing our sales volumes, reducing our costs or developing new or enhanced products with higher selling prices or gross margins.

We expect gross margin to vary over time, and our recent level of product gross margin may not be sustainable.

Our product gross margins vary from quarter to quarter, and the recent level of gross margins may not be sustainable and may be adversely affected in the future by numerous factors, including product mix shifts, product transitions, increased price competition in one or more of the markets in which we compete, increases in material or labor costs, excess product component or obsolescence charges from our contract manufacturers, warranty related issues, or the introduction of new products or entry into new markets with different pricing and cost structures.

Fluctuations in our revenues and operating results on a quarterly and annual basis could cause the market price of our ordinary shares to decline.

Our quarterly and annual revenues and operating results are difficult to predict and have fluctuated in the past, and may fluctuate in the future, from quarter to quarter and year to year. It is possible that our operating results in some quarters and years will be below market expectations. This would likely cause the market price of our ordinary shares to decline. Our quarterly and annual operating results are affected by a number of factors, many of which are outside of our control, including:


	•	unpredictable volume and timing of customer orders, which are not fixed by contract but vary on a purchase order basis;


	•	the loss of one or more of our customers, or a significant reduction or postponement of orders from our customers;

	•	our customers’ sales outlooks, purchasing patterns and inventory levels based on end-user demands and general economic conditions;

	•	seasonal buying trends;

	•	the timing of new product announcements or introductions by us or by our competitors;

	•	our ability to successfully develop, introduce and sell new or enhanced products in a timely manner;

	•	product obsolescence and our ability to manage product transitions;

	•	changes in the relative sales mix of our products;

	•	decreases in the overall average selling prices of our products;

	•	changes in our cost of finished goods; and

	•	the availability, pricing and timeliness of delivery of other components used in our customers’ products.

We base our planned operating expenses in part on our expectations of future revenues, and a significant portion of our expenses is relatively fixed in the short-term. We have limited visibility into customer demand from which to predict future sales of our products. As a result, it is difficult for us to forecast our future revenues and budget our operating expenses accordingly. Our operating results would be adversely affected to the extent customer orders are cancelled or rescheduled. If revenues for a particular quarter are lower than we expect, we likely would not be able to proportionately reduce our operating expenses.

We rely on our ecosystem partners to enhance our product offerings and our inability to continue to develop or maintain such relationships in the future would harm our ability to remain competitive.

We have developed relationships with third parties, which we refer to as ecosystem partners, which provide operating systems, tool support, reference designs and other services designed for specific uses of our products. We believe that these relationships enhance our customers’ ability to get their products to market quickly. If we are unable to continue to develop or maintain these relationships, we might not be able to enhance our customers’ ability to commercialize their products in a timely manner and our ability to remain competitive would be harmed.

We rely primarily upon trade secret, patent and copyright laws and contractual restrictions to protect our proprietary rights, and, if these rights are not sufficiently protected, our ability to compete and generate revenues could suffer.

We seek to protect our proprietary manufacturing specifications, documentation and other written materials primarily under trade secret, patent and copyright laws. We also typically require employees and consultants with access to our proprietary information to execute confidentiality agreements. The steps taken by us to protect our proprietary information may not be adequate to prevent misappropriation of our technology. In addition, our proprietary rights may not be adequately protected because:


	•	people may not be deterred from misappropriating our technologies despite the existence of laws or contracts prohibiting it;

	•	policing unauthorized use of our intellectual property may be difficult, expensive and time-consuming, and we may be unable to determine the extent of any unauthorized use; and

	•	the laws of other countries in which we market our products, such as some countries in the Asia/Pacific region, may offer little or no protection for our proprietary technologies.

Reverse engineering, unauthorized copying or other misappropriation of our proprietary technologies could enable third parties to benefit from our technologies without paying us for doing so. Any inability to adequately protect our proprietary rights could harm our ability to compete, generate revenues and grow our business.

We may not obtain sufficient patent protection on the technology embodied in our products, which could harm our competitive position and increase our expenses.

Our success and ability to compete in the future may depend to a significant degree upon obtaining sufficient patent protection for our proprietary technology. As of December 31, 2009, we had 19 issued patents and 30 patent applications pending in the United States, five issued patents in Taiwan and three issued patent and two applications pending in Israel, each of which covers aspects of the technology in our products. Patents that we currently own do not cover all of the products that we presently sell. Our patent applications may not result in issued patents, and even if they result in issued patents, the patents may not have claims of the scope we seek. Even in the event that these patents are not issued, the applications may become publicly available and proprietary information disclosed in the applications will become available to others. In addition, any issued patents may be challenged, invalidated or declared unenforceable. The term of any issued patent in the United States would be 20 years from its filing date, and if our applications are pending for a long time period, we may have a correspondingly shorter term for any patent that may be issued. Our present and future patents may provide only limited protection for our technology and may not be sufficient to provide competitive advantages to us. For example, competitors could be successful in challenging any issued patents or, alternatively, could develop similar or more advantageous technologies on their own or design around our patents. Also, patent protection in certain foreign countries may not be available or may be limited in scope and any patents obtained may not be as readily enforceable as in the United States and Israel, making it difficult for us to effectively protect our intellectual property from misuse or infringement by other companies in these countries. Our inability to obtain and enforce our intellectual property rights in some countries may harm our business. In addition, given the costs of obtaining patent protection, we may choose not to protect certain innovations that later turn out to be important.

Intellectual property litigation, which is common in our industry, could be costly, harm our reputation, limit our ability to sell our products and divert the attention of management and technical personnel.

The semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights. We have indemnification obligations to most of our customers with respect to infringement of third-party patents and intellectual property rights by our products. If litigation were to be filed against these customers in connection with our technology, we may be required to defend and indemnify such customers.

Questions of infringement in the markets we serve involve highly technical and subjective analyses. Although we have not been involved in intellectual property litigation to date, litigation may be necessary in the future to enforce any patents we may receive and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement or invalidity, and we may not prevail in any such future litigation. Litigation, whether or not determined in our favor or settled, could be costly, could harm our reputation and could divert the efforts and attention of our management and technical personnel from normal business operations. In addition, adverse determinations in litigation could result in the loss of our proprietary rights, subject us to significant liabilities, and require us to seek licenses from third parties or prevent us from licensing our technology or selling our products, any of which could seriously harm our business.

We depend on key and highly skilled personnel to operate our business, and if we are unable to retain our current personnel and hire additional personnel, our ability to develop and successfully market our products could be harmed.

Our business is particularly dependent on the interdisciplinary expertise of our personnel, and we believe our future success will depend in large part upon our ability to attract and retain highly skilled managerial, engineering, finance and sales and marketing personnel. The loss of any key employees or the inability to attract or retain qualified personnel could delay the development and introduction of, and harm our ability to sell our products and harm the market’s perception of us. Competition for qualified engineers in the markets, in which we operate, primarily in Israel where our engineering operations are based, is intense and accordingly, we may not be able to retain or hire all of the engineers required to meet our ongoing and future business needs. If we are unable to attract and retain the highly skilled professionals we need, we may have to forego projects for lack of resources or be unable to staff projects optimally. We believe that our future success is highly dependent on the contributions of our president and chief executive officer and other senior executives. We do not have long-term employment contracts

with our president and chief executive officer or any other key personnel, and their knowledge of our business and industry would be extremely difficult to replace.

In an effort to retain key employees, we may modify our compensation policies by, for example, increasing cash compensation to certain employeesand/or instituting awards of restricted share unitsand/or modifying existing share options. For example, during 2009, we offered eligible employees and contractors the opportunity to exchange certain outstanding share options for a lesser number of replacement options. These modifications of our compensation policies and the requirement to expense the fair value of share options awarded to employees and officers may increase our operating expenses. We cannot be certain that these and any other changes in our compensation policies will or would improve our ability to attract, retain and motivate employees. Our inability to attract and retain additional key employees and the increase in share-based compensation expense could each have an adverse effect on our business, financial condition and results of operations.

We may not be able to manage our future growth effectively, and we may need to incur significant expenditures to address the additional operational and control requirements of our growth.

We are experiencing a period of Company growth and expansion. This expansion has placed, and any future expansion will continue to place, a significant strain on our management, personnel, systems and financial resources. We plan to hire additional employees to support an increase in research and development, as well as increases in our sales and marketing and general and administrative efforts. To successfully manage our growth, we believe we must effectively:


	•	continue to enhance our customer relationship and supply chain management and supporting systems;

	•	implement additional and improve existing administrative, financial and operations systems, procedures and controls;

	•	expand and upgrade our technological capabilities;

	•	manage multiple relationships with our customers, distributors, suppliers, end users and other third parties;

	•	manage the mix of our U.S., Israeli and other foreign operations; and

	•	hire, train, integrate and manage additional qualified engineers for research and development activities, sales and marketing personnel and financial and IT personnel.

Our efforts may require substantial managerial and financial resources and may increase our operating costs even though these efforts may not be successful. If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities, develop new products, satisfy customer requirements, execute our business plan or respond to competitive pressures.

We may experience defects in our products, unforeseen delays, higher than expected expenses or lower than expected manufacturing yields of our products, which could result in increased customer warranty claims, delay our product shipments and prevent us from recognizing the benefits of new technologies we develop.

Although we test our products, they are complex and may contain defects and errors. In the past we have encountered defects and errors in our products. Delivery of products with defects or reliability, quality or compatibility problems may damage our reputation and our ability to retain existing customers and attract new customers. In addition, product defects and errors could result in additional development costs, diversion of technical resources, delayed product shipments, increased product returns, warranty expenses and product liability claims against us which may not be fully covered by insurance. Any of these could harm our business.

In addition, our production of existing and development of new products can involve multiple iterations and unforeseen manufacturing difficulties, resulting in reduced manufacturing yields, delays and increased expenses. The evolving nature of our products requires us to modify our manufacturing specifications, which may result in delays in manufacturing output and product deliveries. We rely on third parties to manufacture our products and currently rely on one manufacturer for our ICs and one manufacturer for our cards and switch systems. Our ability to

offer new products depends on our manufacturers’ ability to implement our revised product specifications, which is costly, time-consuming and complex.

If we fail to maintain an effective system of internal controls, we may not be able to report accurately our financial results or prevent fraud. As a result, current and potential shareholders could lose confidence in our financial reporting, which could harm our business and the trading price of our ordinary shares.

Effective internal controls are necessary for us to provide reliable financial reports and effectively prevent fraud. We have in the past discovered, and may in the future discover, areas of our internal controls that need improvement. Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to report on, and our independent registered public accounting firm to attest to, the effectiveness of our internal control structure and procedures for financial reporting. We have an ongoing program to perform the system and process evaluation and testing necessary to comply with these requirements. We have incurred and expect to continue to incur significant expense and to devote significant management resources to Section 404 compliance. In the event that our chief executive officer, chief financial officer or independent registered public accounting firm determine that our internal control over financial reporting is not effective as defined under Section 404, investor perceptions of our company may be adversely affected and could cause a decline in the market price of our share. In addition, future non-compliance with Section 404 could subject us to a variety of administrative sanctions, including the suspension or delisting of our ordinary shares from The NASDAQ Global Select Market, which could reduce our share price.

We may pursue acquisitions or investments in new or complementary products, technologies and businesses, which could harm our operating results and may disrupt our business.

We may pursue acquisitions of, or investments in, new or complementary products, technologies and businesses. Acquisitions present a number of potential risks and challenges that could, if not met, disrupt our business operations, increase our operating costs and reduce the value to us of the acquisition. For example, if we identify an acquisition candidate, we may not be able to successfully negotiate or finance the acquisition on favorable terms. Even if we are successful, we may not be able to integrate the acquired businesses, products or technologies into our existing business and products. Furthermore, potential acquisitions and investments, whether or not consummated, may divert our management’s attention and require considerable cash outlays at the expense of our existing operations. In addition, to complete future acquisitions, we may issue equity securities, incur debt, assume contingent liabilities or have amortization expenses and write-downs of acquired assets, which could adversely affect our profitability.

We have made, and could make in the future, investments in technology companies, including privately-held companies in a development stage. Many of these private equity investments are inherently risky because the companies’ businesses may never develop, and we may incur losses related to these investments. In addition, we may be required to write down the carrying value of these investments to reflectother-than-temporary declines in their value, which could have a material adverse effect on our financial position and results of operations.

Unanticipated changes in our tax provisions or adverse outcomes resulting from examination of our income tax returns could adversely affect our results of operations.

We are subject to income taxes in the United States and various foreign jurisdictions. Our effective income tax could be adversely affected by changes in tax laws or interpretations of those tax laws, by changes in the mix of earnings in countries with differing statutory tax rates, by discovery of new information in the course of our tax return preparation process, or by changes in the valuation of our deferred tax assets and liabilities. Our effective income tax rates are also affected by intercompany transactions for sales, services, funding and other items. Given the increased global scope of our operations, and the complexity of global tax and transfer pricing rules and regulations, it has become increasingly difficult to estimate earnings within each tax jurisdiction. If actual earnings within a tax jurisdiction differ materially from our estimates, we may not achieve our expected effective tax rate. Additionally, our effective tax rate may be impacted by the tax effects of acquisitions, newly enacted tax legislation, share-based compensation and uncertain tax positions. Finally, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities which may result in the assessment of

additional income taxes. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. However, unanticipated outcomes from these continuous examinations could have a material adverse effect on our financial condition or results of operations.

Changes to financial accounting standards may affect our results of operations and cause us to change our business practices.

We prepare our financial statements to conform to generally accepted accounting principles, or GAAP, in the United States. These accounting principles are subject to interpretation by the Financial Accounting Standards Board, or FASB, the SEC and various bodies formed to interpret and create appropriate accounting policies. A change in those policies can have a significant effect on our reported results and may affect our reporting of transactions completed before a change is announced. Changes to those rules or the questioning of current practices may adversely affect our reported financial results or the way we conduct our business. For example, accounting policies affecting many aspects of our business, including rules relating to employee share option grants, have been revised. The FASB and other agencies have made changes to GAAP that required us, as of our first quarter of 2006, to record a charge to earnings for the estimated fair value of employee share option grants and other equity incentives, whereas under previous accounting rules charges were required only for the intrinsic value, if any, of such awards to employees. We may have significant and ongoing accounting charges under the new rules resulting from option grants and other equity incentive expensing that could reduce our net income. In addition, since historically we have used equity-related compensation as a component of our total employee compensation program, the accounting change could make the use of equity-related compensation less attractive to us and therefore make it more difficult for us to attract and retain employees.

Also, the SEC released a proposed roadmap regarding the potential use by U.S. issuers of financial statements prepared in accordance with International Financial Reporting Standards, or IFRS. Under the proposed roadmap, we may be required to prepare financial statements in accordance with IFRS. The SEC announced it will make a determination in 2011 regarding the mandatory adoption of these new standards. Adoption of IFRS may have material impact on our results of operations.

Our business is subject to the risks of earthquakes, fires, floods and other natural catastrophic events, and to interruption by manmade problems such as computer viruses or terrorism.

Our U.S. corporate offices are located in the San Francisco Bay Area, a region known for seismic activity. A significant natural disaster, such as an earthquake, fire or flood, could have a material adverse impact on our business, operating results and financial condition. In addition, our servers are vulnerable to computer viruses, break-ins and similar disruptions from unauthorized tampering with our computer systems. In addition, acts of terrorism could cause disruptions in our or our customers’ businesses or the economy as a whole. To the extent that such disruptions result in delays or cancellations of customer orders, or the deployment of our products, our business, operating results and financial condition would be adversely affected.

Risks Related to Our Industry

Due to the cyclical nature of the semiconductor industry, our operating results may fluctuate significantly, which could adversely affect the market price of our ordinary shares.

The semiconductor industry is highly cyclical and subject to rapid change and evolving industry standards and, from time to time, has experienced significant downturns. These downturns are characterized by decreases in product demand, excess customer inventories and accelerated erosion of prices. These factors could cause substantial fluctuations in our net revenues and in our operating results. Any downturns in the semiconductor industry may be severe and prolonged, and any failure of this industry to fully recover from downturns could harm our business. The semiconductor industry also periodically experiences increased demand and production capacity constraints, which may affect our ability to ship products. Accordingly, our operating results may vary significantly as a result of the general conditions in the industry, which could cause our share price to decline.

The demand for semiconductors is affected by general economic conditions, which could impact our business.

The semiconductor industry is affected by general economic conditions, and a downturn may result in decreased demand for our products and adversely affect our operating results. Our business has been adversely affected by previous economic downturns. For example, during the global economic downturn in 2002 to 2003, demand for many computer and consumer electronics products suffered as consumers delayed purchasing decisions or changed or reduced their discretionary spending. As a result, demand for our products suffered and we had to implement restructuring initiatives to align our corporate spending with a slower than anticipated revenue growth during that timeframe. Additionally, general worldwide economic conditions have recently experienced a downturn due to market instability, slower economic activity, concerns about inflation and deflation, increased energy costs, decreased consumer confidence, reduced corporate profits and capital spending, adverse business conditions and liquidity concerns. These conditions make it extremely difficult for our customers, our vendors and us to accurately forecast and plan future business activities. We cannot predict the timing, strength or duration of any economic slowdown or subsequent economic recovery, worldwide, or in the semiconductor industry. If the economy or markets in which we operate continue at their present levels, our business, financial condition and results of operations will likely be materially and adversely affected.

The semiconductor industry is highly competitive, and we cannot assure you that we will be able to compete successfully against our competitors.

The semiconductor industry is highly competitive. Increased competition may result in price pressure, reduced profitability and loss of market share, any of which could seriously harm our revenues and results of operations. Competition principally occurs at the design stage, where a customer evaluates alternative design solutions. We continually face intense competition from semiconductor interconnect solutions companies. Some of our competitors have greater financial and other resources than we have with which to pursue engineering, manufacturing, marketing and distribution of their products. As a result, they may be able to respond more quickly to changing customer demands or devote greater resources to the development, promotion and sales of their products than we can. We cannot assure you that we will be able to increase or maintain our revenues and market share, or compete successfully against our current or future competitors in the semiconductor industry.

Risks Related to Operations in Israel and Other Foreign Countries

Regional instability in Israel may adversely affect business conditions and may disrupt our operations and negatively affect our revenues and profitability.

We have engineering facilities and corporate and sales support operations and, as of December 31, 2009, 265 full-time and 42 part-time employees located in Israel. A significant amount of our assets is located in Israel. Accordingly, political, economic and military conditions in Israel may directly affect our business. Since the establishment of the State of Israel in 1948, a number of armed conflicts have taken place between Israel and its Arab neighbors, as well as incidents of civil unrest. During the winter of 2008 and the summer of 2006, Israel was engaged in armed conflicts with Hamas and Hezbollah. These conflicts involved missile strikes against civilian targets in southern and northern Israel, and negatively affected business conditions in Israel. In addition, Israel and companies doing business with Israel have, in the past, been the subject of an economic boycott. Although Israel has entered into various agreements with Egypt, Jordan and the Palestinian Authority, Israel has been and is subject to civil unrest and terrorist activity, with varying levels of severity, since September 2000. Any future armed conflicts or political instability in the region may negatively affect business conditions and adversely affect our results of operations. Parties with whom we do business have sometimes declined to travel to Israel during periods of heightened unrest or tension, forcing us to make alternative arrangements when necessary. In addition, the political and security situation in Israel may result in parties with whom we have agreements involving performance in Israel claiming that they are not obligated to perform their commitments under those agreements pursuant to force majeure provisions in the agreements.

We can give no assurance that security and political conditions will have no impact on our business in the future. Hostilities involving Israel or the interruption or curtailment of trade between Israel and its present trading

partners could adversely affect our operations and could make it more difficult for us to raise capital. While we did not sustain damages from the conflicts with Hamas and Hezbollah referred to above, our Israeli operations, which are located in northern Israel, are within range of Hezbollah missiles and we or our immediate surroundings may sustain damages in a missile attack, which could adversely affect our operations.

In addition, our business insurance does not cover losses that may occur as a result of events associated with the security situation in the Middle East. Although the Israeli government currently covers the reinstatement value of direct damages that are caused by terrorist attacks or acts of war, we cannot assure you that this government coverage will be maintained. Any losses or damages incurred by us could have a material adverse effect on our business.

Our operations may be negatively affected by the obligations of our personnel to perform military service.

Generally, all non-exempt male adult citizens and permanent residents of Israel under the age of 45 (or older, for citizens with certain occupations), including some of our officers, directors and employees, are obligated to perform military reserve duty annually, and are subject to being called to active duty at any time under emergency circumstances. In the event of severe unrest or other conflict, individuals could be required to serve in the military for extended periods of time. In response to increases in terrorist activity, there have been periods of significantcall-ups of military reservists, and some of our employees, including those in key positions, have been called upon in connection with armed conflicts. It is possible that there will be additionalcall-ups in the future. Our operations could be disrupted by the absence for a significant period of one or more of our officers, directors or key employees due to military service. Any such disruption could adversely affect our operations.

Our operations may be affected by negative economic conditions or labor unrest in Israel.

Due to significant economic measures adopted by the Israeli government, there were several general strikes and work stoppages in Israel in 2003 and 2004, affecting all banks, airports and ports. These strikes had an adverse effect on the Israeli economy and on business, including our ability to deliver products to our customers and to receive raw materials from our suppliers in a timely manner. From time to time, the Israeli trade unions threaten strikes or work stoppages, which, if carried out, may have a material adverse effect on the Israeli economy and our business.

We are susceptible to additional risks from our international operations.

We derived 47%, 48% and 64% of our revenues in the years ended December 31, 2007, 2008 and 2009, respectively, from sales outside North America. As a result, we face additional risks from doing business internationally, including:


	•	reduced protection of intellectual property rights in some countries;

	•	difficulties in staffing and managing foreign operations;

	•	longer sales and payment cycles;

	•	greater difficulties in collecting accounts receivable;

	•	adverse economic conditions;

	•	seasonal reductions in business activity;

	•	potentially adverse tax consequences;

	•	laws and business practices favoring local competition;

	•	costs and difficulties of customizing products for foreign countries;

	•	compliance with a wide variety of complex foreign laws and treaties;

	•	licenses, tariffs, other trade barriers, transit restrictions and other regulatory or contractual limitations on our ability to sell or develop our products in certain foreign markets;


	•	foreign currency exchange risks;

	•	fluctuations in freight rates and transportation disruptions;

	•	political and economic instability;

	•	variance and unexpected changes in local laws and regulations;

	•	natural disasters and public health emergencies; and

	•	trade and travel restrictions.

Our principal research and development facilities are located in Israel, and our directors, executive officers and other key employees are located primarily in Israel and the United States. In addition, we engage sales representatives in various countries throughout the world to market and sell our products in those countries and surrounding regions. If we encounter any of the above risks in our international operations, we could experience slower than expected revenue growth and our business could be harmed.

It may be difficult to enforce a U.S. judgment against us, our officers and directors or to assert U.S. securities law claims in Israel.

We are incorporated in Israel. Four of our executive officers and one of our directors, who is also an executive officer, and some of our accountants and attorneys are non-residents of the United States and are located in Israel, and a significant amount of our assets and the assets of these persons are located outside the United States. Two of our executive officers and five of our directors are located in the United States. Therefore, it may be difficult to enforce a judgment obtained in the United States against us or any of these persons in U.S. or Israeli courts based on the civil liability provisions of the U.S. federal securities laws.

In addition, we have been informed by our legal counsel in Israel, Yigal Arnon & Co., that it may be difficult for a shareholder to enforce civil liabilities under U.S. securities law claims in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on a violation of U.S. securities laws because Israel is not the most appropriate forum to bring such a claim. In addition, even if an Israeli court agrees to hear a claim, it may determine that Israeli law, and not U.S. law, is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be proved in court as a fact, which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law. There is little binding case law in Israel addressing the matters described above.

Provisions of Israeli law may delay, prevent or make difficult an acquisition of us, which could prevent a change of control and therefore depress the price of our shares.

Israeli corporate law regulates mergers, requires tender offers for acquisitions of shares above specified thresholds, requires special approvals for transactions involving directors, officers or significant shareholders and regulates other matters that may be relevant to these types of transactions. For example, a merger may not be completed unless at least 50 days have passed from the date that a merger proposal was filed by each merging company with the Israeli Registrar of Companies and at least 30 days from the date that the shareholders of both merging companies approved the merger. In addition, the approval of a majority of each class of securities of the target company is required to approve a merger. Israeli corporate law further requires that any person who wishes to acquire more than a specified percentage of the company’s share capital complies with certain tender offer procedures. In addition, Israeli corporate law allows us to create and issue shares having rights different from those attached to our ordinary shares, including rights that may delay or prevent a takeover or otherwise prevent our shareholders from realizing a potential premium over the market value of their ordinary shares. The authorization of a new class of shares would require an amendment to our articles of association, which requires the prior approval of the holders of a majority of our shares at a general meeting.

These provisions could delay, prevent or impede an acquisition of us, even if such an acquisition would be considered beneficial by some of our shareholders. See “Risk Factors — Provisions of Israeli law could delay or prevent an acquisition of our company, even if the acquisition would be beneficial to our shareholders, and could make it more difficult for shareholders to change management” for a further discussion of this risk factor.

Exchange rate fluctuations between the U.S. dollar and the NIS may negatively affect our earnings.

Although all of our revenues and a majority of our expenses are denominated in U.S. dollars, a significant portion of our research and development expenses are incurred in new Israeli shekels, or NIS. As a result, we are exposed to risk to the extent that the inflation rate in Israel exceeds the rate of devaluation of the NIS in relation to the U.S. dollar or if the timing of these devaluations lags behind inflation in Israel. In that event, the U.S. dollar cost of our research and development operations in Israel will increase and our U.S. dollar-measured results of operations will be adversely affected. To the extent that the value of the NIS increases against the U.S. dollar, our expenses on a U.S. dollar cost basis increase. We cannot predict any future trends in the rate of inflation in Israel or the rate of appreciation of the NIS against the U.S. dollar. The Israeli rate of inflation amounted to 3.4%, 3.8% and 3.9% for the years ended December 31, 2007, 2008 and 2009, respectively. The increase in value of the NIS against the U.S. dollar amounted to 8.9%, 1.1% and 0.7% in the years ended December 31, 2007, 2008 and 2009, respectively. Our operations also could be adversely affected if we are unable to guard against currency fluctuations in the future. Further, because all of our international revenues are denominated in U.S. dollars, a strengthening of the dollar versus other currencies could make our products less competitive in foreign markets and the collection of receivables more difficult. To help manage this risk we have recently been engaged in foreign currency hedging activities. These measures, however, may not adequately protect us from material adverse effects due to the impact of inflation in Israel and changes in value of the NIS against the U.S. dollar.

The government tax benefits that we currently receive require us to meet several conditions and may be terminated or reduced in the future, which would increase our costs.

Some of our operations in Israel have been granted “Approved Enterprise” status by the Investment Center in the Israeli Ministry of Industry Trade and Labor, which makes us eligible for tax benefits under the Israeli Law for Encouragement of Capital Investments, 1959. The availability of these tax benefits is subject to certain requirements, including, among other things, making specified investments in fixed assets and equipment, financing a percentage of those investments with our capital contributions, complying with our marketing program which was submitted to the Investment Center, filing of certain reports with the Investment Center and complying with Israeli intellectual property laws. If we do not meet these requirements in the future, these tax benefits may be cancelled and we could be required to refund any tax benefits that we have already received plus interest and penalties thereon. The tax benefits that our current “Approved Enterprise” program receives may not be continued in the future at their current levels or at all. If these tax benefits were reduced or eliminated, the amount of taxes that we pay would likely increase, which could adversely affect our results of operations. Additionally, if we increase our activities outside of Israel, for example, by acquisitions, our increased activities may not be eligible for inclusion in Israeli tax benefit programs.

The Israeli government grants that we received require us to meet several conditions and may be reduced or eliminated due to government budget cuts, and these grants restrict our ability to manufacture and engineer products and transfer know-how outside of Israel and require us to satisfy specified conditions.

We have received, and may receive in the future, grants from the government of Israel through the Office of the Chief Scientist of Israel’s Ministry of Industry, Trade and Labor, or the OCS, for the financing of a portion of our research and development expenditures in Israel. When know-how or products are developed using OCS grants, the terms of these grants restrict the transfer of the know-how out of Israel. Transfer of know-how abroad is subject to various conditions, including payment of a percentage of the consideration paid to us or our shareholders in the transaction in which the technology is transferred. In addition, any decrease of the percentage of manufacturing performed locally, as originally declared in the application to the OCS, may require us to notify, or to obtain the approval of the OCS and may result in increased royalty payments to the OCS. These restrictions may impair our ability to enter into agreements for those products or technologies without the approval of the OCS. We cannot be certain that any approval of the OCS will be obtained on terms that are acceptable to us, or at all. Furthermore, in the event that we undertake a transaction involving the transfer to a non-Israeli entity of technology developed with OCS funding pursuant to a merger or similar transaction, the consideration available to our shareholders may be reduced by the amounts we are required to pay to the OCS. Any approval, if given, will generally be subject to additional financial obligations. If we fail to comply with the conditions imposed by the OCS, including the

payment of royalties with respect to grants received, we may be required to refund any payments previously received, together with interest and penalties. We have received total grants from the OCS in the amount of $2.8 million. As of December 31, 2008, we concluded all our obligations in respect of royalties payable to the OCS.

Your rights and responsibilities as a shareholder will be governed by Israeli law and differ in some respects from the rights and responsibilities of shareholders under U.S. law.

We are incorporated under Israeli law. The rights and responsibilities of holders of our ordinary shares are governed by our amended and restated articles of association and by Israeli law. These rights and responsibilities differ in some respects from the rights and responsibilities of shareholders in typical U.S. corporations. In particular, a shareholder of an Israeli company has a duty to act in good faith toward the company and other shareholders and to refrain from abusing his, her or its power in the company, including, among other things, in voting at the general meeting of shareholders on certain matters.

Risks Related to Our Ordinary Shares

The price of our ordinary shares may continue to be volatile, and the value of an investment in our ordinary shares may decline.

We sold ordinary shares in our initial public offering in February 2007 at a price of $17.00 per share, and our shares have subsequently traded as low as $6.02 per share. Factors that could cause volatility in the market price of our ordinary shares include, but are not limited to:


	•	quarterly variations in our results of operations or those of our competitors;

	•	announcements by us, our customers or rumors from sources other than the Company related to acquisitions, new products, significant contracts, commercial relationships or capital commitments;

	•	our ability to develop and market new and enhanced products on a timely basis;

	•	disruption to our operations;

	•	geopolitical instability;

	•	the emergence of new sales channels in which we are unable to compete effectively;

	•	any major change in our board of directors or management;

	•	changes in financial estimates, including our ability to meet our future revenue and operating profit or loss projections;

	•	changes in governmental regulations or in the status of our regulatory approvals;

	•	general economic conditions and slow or negative growth of related markets;

	•	commencement of, or our involvement in, litigation;

	•	changes in earnings estimates or recommendations by securities analysts;

	•	continuing international conflicts and acts of terrorism; and

	•	changes in accounting rules.

In addition, the stock markets in general, and the markets for semiconductor stocks in particular, have experienced extreme volatility that often has been unrelated to the operating performance of the issuer. These broad market fluctuations may adversely affect the trading price or liquidity of our ordinary shares. In the past, when the market price of a stock has been volatile and declined, holders of that stock have sometimes instituted securities class action litigation against the issuer. If any of our shareholders were to bring such a lawsuit against us, we could incur substantial costs defending the lawsuit and the attention of our management would be diverted from the operation of our business.

The ownership of our ordinary shares may continue to be highly concentrated, and your interests may conflict with the interests of our significant shareholders.

Our executive officers and directors and their affiliates, together with our current significant shareholders, beneficially owned approximately 29% of our outstanding ordinary shares as of December 31, 2009. Moreover, based on information filed with SEC, two of our major shareholders, Fred Alger Management and Fidelity Management and Research, beneficially owned approximately 19% of our outstanding ordinary shares as of December 31, 2009. Accordingly, these shareholders, acting as a group, have significant influence over the outcome of corporate actions requiring shareholder approval, including the election of directors, any merger, consolidation or sale of all or substantially all of our assets or any other significant corporate transaction. These shareholders could delay or prevent a change of control of our company, even if such a change of control would benefit our other shareholders. The significant concentration of share ownership may adversely affect the trading price of our ordinary shares due to investors’ perception that conflicts of interest may exist or arise.

If we sell our ordinary shares in future financings, ordinary shareholders could experience immediate dilution and, as a result, our share price may go down.

We may from time to time issue additional ordinary shares at a discount from the current trading price of our ordinary shares. As a result, our ordinary shareholders would experience immediate dilution upon the purchase of any ordinary shares sold at such discount. In addition, as opportunities present themselves, we may enter into equity financings or similar arrangements in the future, including the issuance of debt securities, preferred shares or ordinary shares. If we issue ordinary shares or securities convertible into ordinary shares, our ordinary shareholders could experience dilution.

Provisions of Israeli law could delay or prevent an acquisition of our company, even if the acquisition would be beneficial to our shareholders, and could make it more difficult for shareholders to change management.

Provisions of our amended and restated articles of association may discourage, delay or prevent a merger, acquisition or other change in control that shareholders may consider favorable, including transactions in which shareholders might otherwise receive a premium for their shares. In addition, these provisions may frustrate or prevent any attempt by our shareholders to replace or remove our current management by making it more difficult to replace or remove our board of directors. These provisions include:


	•	no cumulative voting; and

	•	an advance notice requirement for shareholder proposals and nominations.

Furthermore, Israeli tax law treats some acquisitions, particularlyshare-for-share swaps between an Israeli company and a foreign company, less favorably than U.S. tax law. Israeli tax law generally provides that a shareholder who exchanges our shares for shares in a foreign corporation is treated as if the shareholder has sold the shares. In such a case, the shareholder will generally be subject to Israeli taxation on any capital gains from the sale of shares (after two years, with respect to one half of the shares, and after four years, with respect to the balance of the shares, in each case unless the shareholder sells such shares at an earlier date), unless a relevant tax treaty between Israel and the country of the shareholder’s residence exempts the shareholder from Israeli tax. Please see “Risk Factors — Provisions of Israeli law may delay, prevent or make difficult an acquisition of us, which could prevent a change of control and therefore depress the price of our shares” for a further discussion of Israeli laws relating to mergers and acquisitions. These provisions in our amended and restated articles of association and other provisions of Israeli law could limit the price that investors are willing to pay in the future for our ordinary shares.

We have never paid cash dividends on our share capital, and we do not anticipate paying any cash dividends in the foreseeable future.

We have never declared or paid cash dividends on our share capital, nor do we anticipate paying any cash dividends on our share capital in the foreseeable future. We currently intend to retain all available funds and any

future earnings to fund the development and growth of our business. As a result, capital appreciation, if any, of our ordinary shares will be your sole source of gain for the foreseeable future.

We may incur increased costs as a result of changes in laws and regulations relating to corporate governance matters.

Changes in the laws and regulations affecting public companies, including rules adopted by the SEC and by The NASDAQ Stock Market, will result in increased costs to us as we respond to their requirements. These laws and regulations could make it more difficult or more costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements.


ITEM 1B —	*UNRESOLVED STAFF COMMENTS*

None.


ITEM 2 —	*PROPERTIES*

Our U.S. business headquarters are located in Sunnyvale, California, and our engineering headquarters are located in Yokneam, Israel. Our facility in Sunnyvale, California comprises of approximately 25,500 square feet and has a lease term that expires on June 4, 2014. Our facilities in Israel comprise an aggregate of approximately 103,700 square feet and have lease terms that expire at various dates through 2012.

We believe that our existing facilities are adequate to meet our current requirements and that suitable additional or substitute space will be available on acceptable terms to accommodate our foreseeable needs.


ITEM 3 —	*LEGAL PROCEEDINGS*

We are not currently involved in any material legal proceedings. We may, from time to time, become a party to various legal proceedings arising in the ordinary course of business. We may also be indirectly affected by administrative or court proceedings or actions in which we are not involved but which have general applicability to the semiconductor industry.

Dividends

We have never declared or paid any cash dividends on our ordinary shares in the past, and we do not anticipate paying cash dividends in the foreseeable future. The Israeli Companies Law, 1999, or the Companies Law, also restricts our ability to declare dividends. We can only distribute dividends from profits (as defined in the Companies Law), or if we do not meet the profit test, with court approval, provided in each case that there is no reasonable concern that the dividend distribution will prevent us from meeting our existing and foreseeable obligations as they come due.

Securities Authorized for Issuance under Equity Compensation Plans

Our equity compensation plan information required by this item is incorporated by reference to the information in Part III, Item 12 of this report. For additional information on our share incentive plans and activity, see Note 10, “Share Option Plans” included in Part IV, Item 15 of this report.

Recent Sales of Unregistered Securities

None.

Use of Proceeds from Registered Securities

Our initial public offering of 6,900,000 ordinary shares was effected through a Registration Statement onForm S-1 (FileNo. 333-137659) that was declared effective by the Securities and Exchange Commission on February 7, 2007. We issued all 6,900,000 shares on February 13, 2007 for gross proceeds of $117,300,000, after which the offering was terminated. The underwriters of the offering were Credit Suisse Securities (USA) LLC, J.P. Morgan Securities Inc., Thomas Weisel Partners LLC and Jefferies & Company, Inc. We paid the underwriters a commission of $8,211,000 and incurred additional offering expenses of approximately $3,136,000. After deducting the underwriters’ commission and the offering expenses, we received net proceeds of approximately $105,953,000. No payments for such expenses were made directly or indirectly to (i) any of our directors, officers or their associates, (ii) any person(s) owning 10% or more of any class of our equity securities or (iii) any of our affiliates. The net proceeds from our initial public offering have been primarily invested into short-term marketable government agency obligations, commercial paper and corporate notes. There has been no material change in the planned use of proceeds from our initial public offering as described in our final prospectus filed with the SEC pursuant to Rule 424(b).

ITEM 7 —	*MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS*

You should read the following discussion of our financial condition and results of operations in conjunction with the financial statements and the notes thereto included elsewhere in this report. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this report, particularly in the “Risk Factors.”

Overview

General

directly on circuit boards or inserting adapter cards into slots on the circuit board. We have been shipping our Infinband products since 2001 and our Ethernet products since 2007. During 2008 we introduced Virtual Protocol Interconnect, or VPI, into our adapter ICs and cards. VPI provides the ability for an adapter to automatically sense whether a communications port is connected to an Ethernet fabric or an InfiniBand fabric. Data centers which use VPI adapters in their servers have the ability to dynamically select the connectivity protocol for use by those servers. We have established significant expertise with high-performance interconnect solutions from successfully developing and implementing multiple generations of our products. Our expertise enables us to develop and deliver products that serve as building blocks for creating reliable and scalable InfiniBand and Ethernet solutions with leading performance at significantly lower cost than products based on alternative interconnect solutions.

We outsource our manufacturing, assembly, packaging and production test functions, which enables us to focus on the design, development, sales and marketing of our products. As a result, our business has relatively low capital requirements. However, our ability to bring new products to market, fulfill customer orders and achieve long-term growth depends on our ability to maintain sufficient technical personnel and obtain sufficient external subcontractor capacity.

We have experienced growth in our total revenues in each of the last three years. Our revenues increased from $48.5 million for the year ended December 31, 2006 to $84.1 million to $107.7 million to $116.0 million for the years ended December 31, 2007, 2008 and 2009, respectively. In order to increase our annual revenues, we must continue to achieve design wins over other InfiniBand and Ethernet providers and providers of competing interconnect technologies. We consider a design win to occur when an original equipment manufacturer, or OEM, or contract manufacturer notifies us that it has selected our products to be incorporated into a product or system under development. Because the life cycles for our customers’ products can last for several years if these products have successful commercial introductions, we expect to continue to generate revenues over an extended period of time for each successful design win.

It is difficult for us to forecast the demand for our products, in part because of the highly complex supply chain between us and the end-user markets that incorporate our products. Demand for new features changes rapidly. Due to our lengthy product development cycle, it is critical for us to anticipate changes in demand for our various product features and the applications they serve to allow sufficient time for product design. Our failure to accurately forecast demand can lead to product shortages that can impede production by our customers and harm our relationship with these customers. Conversely, our failure to forecast declining demand or shifts in product mix can result in excess or obsolete inventory.

Revenues. We derive revenues from sales of our ICs, cards, switch systems and accessories. To date, we have derived a substantial portion of our revenues from a relatively small number of customers. Sales to our top ten customers represented 79%, 79% and 81% of our total revenues for the years ended December 31, 2009, 2008 and 2007, respectively. Sales to customers representing 10% or more of revenues accounted for 36%, 47% and 56% of our total revenues for the years ended December 31, 2009, 2008 and 2007, respectively. The loss of one or more of our principal customers or the reduction or deferral of purchases of our products by one of these customers could cause our revenues to decline materially if we are unable to increase our revenues from other customers.

Cost of revenues and gross profit. The cost of revenues consists primarily of the cost of silicon wafers purchased from our foundry supplier, Taiwan Semiconductor Manufacturing Company, or TSMC, costs associated with the assembly, packaging and production testing of our products by Advanced Semiconductor Engineering, or ASE, outside processing costs associated with the manufacture of our host channel adapters, or HCA cards, and switch systems by Flextronics International Ltd., or Flextronics, royalties due to third parties, including the Office of the Chief Scientist of Israel’s Ministry of Industry, Trade and Labor, or the OCS, and the Binational Industrial Research and Development Foundation, warranty costs, excess and obsolete inventory costs and costs of personnel associated with production management and quality assurance. In addition, after we purchase wafers from our foundries, we also have the yield risk related with manufacturing these wafers into semiconductor devices. Manufacturing yield is the percentage of acceptable product resulting from the manufacturing process, as identified when the product is tested as a finished IC. If our manufacturing yields decrease, our cost per unit increases, which could have a significant adverse impact on our cost of revenues. We do not have long-term pricing agreements with TSMC and ASE. Accordingly, our costs are subject to price fluctuations based on the cyclical demand for

semiconductors. As of December 31, 2008, we had concluded all our obligations in respect of royalties payable to the OCS.

We purchase our inventory pursuant to standard purchase orders. We estimate that lead times for delivery of our finished semiconductors from our foundry supplier and assembly, packaging and production testing subcontractor are approximately three to four months, lead times for delivery from our HCA card manufacturing subcontractor are approximately eight to ten weeks, and lead times for delivery from our switch systems manufacturing subcontractor are approximately twelve weeks. We build inventory based on forecasts of customer orders rather than the actual orders themselves. In addition, as customers are increasingly seeking opportunities to reduce their lead times, we may be required to increase our inventory to meet customer demand.

We expect our cost of revenues to increase over time as a result of the expected increase in our sales volume. We expect our cost of revenues as a percentage of sales to increase in the future as a result of a reduction in the average sale price of our products and a higher percentage of revenue deriving from sales of HCA cards and switch systems, which generally yield lower gross margins. This trend will depend on overall customer demand for our products, our product mix, competitive product offerings and related pricing and our ability to reduce manufacturing costs.

Operational expenses

Research and development expenses. Our research and development expenses consist primarily of salaries, share-based compensation and associated costs for employees engaged in research and development, costs associated with computer aided design software tools, depreciation expense and tape out costs. Tape out costs are expenses related to the manufacture of new products, including charges for mask sets, prototype wafers, mask set revisions and testing incurred before releasing new products. We anticipate these expenses will increase in future periods based on an increase in personnel to support our product development activities and the introduction of new products. We anticipate that our research and development expenses may fluctuate over the course of a year based on the timing of our product tape outs.

We received grants from the OCS for several projects. Under the terms of these grants, if products developed from an OCS-funded project generate revenue, we are required to pay a royalty of 4 to 4.5% of the net sales as soon as we begin to sell such products until 120% of the dollar value of the grant plus interest at LIBOR is repaid. All of the grants we have received from the OCS have resulted in IC products sold by us. We received no grants from the OCS during the years ended December 31, 2009, 2008 and 2007. In total, we have received grants from OCS in the amount of $2.8 million. As of December 31, 2008, we had concluded all our obligations in respect of royalties payable to the OCS.

The terms of OCS grants generally prohibit the manufacture of products developed with OCS funding outside of Israel without the prior consent of the OCS. The OCS has approved the manufacture outside of Israel of our IC products, subject to an undertaking by us to pay the OCS royalties on the sales of our OCS-supported products until such time as the total royalties paid equal 120% of the amount of OCS grants.

Under applicable Israeli law, OCS consent is also required to transfer technologies developed with OCS funding to third parties in Israel. Transfer of OCS-funded technologies outside of Israel is permitted with the approval of the OCS and in accordance with the restrictions and payment obligations set forth under Israeli law. Israeli law further specifies that both the transfer of know-how as well as the transfer of intellectual property rights in such know-how are subject to the same restrictions. These restrictions do not apply to exports of products from Israel or the sale of products developed with these technologies.

Sales and marketing expenses. Sales and marketing expenses consist primarily of salaries, share-based compensation and associated costs for employees engaged in sales, marketing and customer support, commission payments to external, third party sales representatives, advertising and trade shows, promotions and travel. We expect these expenses will increase in absolute dollars in future periods based on an increase in sales and marketing personnel and increased commission payments.

General and administrative expenses. General and administrative expenses consist primarily of salaries and associated costs for employees engaged in finance, human resources and administrative activities and charges for

accounting and corporate legal fees. We expect these expenses will increase in absolute dollars in future periods based on an increase in personnel to support our business activities.

Taxes on Income

Our operations in Israel have been granted “Approved Enterprise” status by the Investment Center of the Israeli Ministry of Industry, Trade and Labor, which makes us eligible for tax benefits under the Israeli Law for Encouragement of Capital Investments, 1959. Under the terms of the Approved Enterprise program, income that is attributable to our operations in Yokneam, Israel will be exempt from income tax for a period of ten years commencing when we first generate taxable income after setting off our losses from prior years. Income that is attributable to our operations in Tel Aviv, Israel will be exempt from income tax for a period of two years commencing when we first generate taxable income and will be subject to a reduced income tax rate (generally 10 to 25%, depending on the percentage of foreign investment in the company) for the following five to eight years. We expect the Approved Enterprise Tax Holiday associated with our Yokneam and Tel Aviv operations to begin in 2011. The Yokneam Tax Holiday is expected to expire in 2020 and the Tel Aviv Tax Holiday is expected to expire between 2015 and 2018.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.

We believe that the assumptions and estimates associated with revenue recognition, allowance for doubtful accounts, fair value of financial instruments, short-term investments, inventory valuation, and impairment of long-lived assets, warranty provision, share-based compensation and income taxes have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates. For further information on all of our significant accounting policies, please see Note 1, “The Company and Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements, included in Part IV, Item 15 of this report.

Revenue recognition

We recognize revenue from the sales of products when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred; (3) the price is fixed or determinable; and (4) collection is reasonably assured. We use a binding purchase order or a signed agreement as evidence of an arrangement. Delivery occurs when goods are shipped and title and risk of loss transfer to the customer. Our standard arrangement with our customers typically includesfreight-on-board shipping point and no right of return and no customer acceptance provisions. The customer’s obligation to pay and the payment terms are set at the time of delivery and are not dependent on the subsequent resale of the product. We determine whether collectibility is probable on acustomer-by-customer basis. When assessing the probability of collection, we consider the number of years the customer has been in business and the history of our collections. Customers are subject to a credit review process that evaluates the customers’ financial positions and ultimately their ability to pay. If it is determined at the outset of an arrangement that collection is not probable, no product is shipped and no revenue is recognized unless cash is received in advance.

A portion of our sales are made to distributors under agreements which contain a limited right to return unsold product and price protection provisions. We recognize revenue from these distributors based on the sell-through method using inventory information provided by the distributor. Additionally, we maintain accruals and allowances for price protection and cooperative marketing programs. We classify the costs of these programs based on the identifiable benefit received as either a reduction of revenue, a cost of sale or an operating expense.

We also maintain inventory, or hubbing, arrangements with certain customers. Pursuant to these arrangements we deliver products to a customer or a designated third party warehouse based upon the customer’s projected needs, but do not recognize product revenue unless and until the customer reports it has removed our product from the warehouse to be incorporated into its end products.

We recognize revenue from the sale of hardware products and software bundled with hardware that is essential to the functionality of the hardware in accordance with general revenue recognition accounting guidance. We recognize revenue in accordance with industry specific software accounting guidance for the following types of sales transactions: (i) standalone sales of software products, (ii) sales of software upgrades and (iii) sales of software bundled with hardware not essential to the functionality of the hardware.

For multiple element arrangements that include a combination of hardware, software and services, such as post-contract customer support, the arrangement consideration is allocated to the separate elements based on fair value. Effective October 1, 2009, we adopted authoritative guidance allowing the allocation of the arrangement consideration using our best estimate of selling price. The change was made prospectively from the beginning of the fiscal year 2009 and did not have a material impact on our consolidated financial statements, including interim consolidated financial statements reported in the year of adoption. If an arrangement includes undelivered elements that are not essential to the functionality of the delivered elements, we defer the fair value or best estimate selling price of the undelivered elements and the residual revenue is allocated to the delivered elements. If the undelivered elements are essential to the functionality of the delivered elements, no revenue is recognized. In the arrangements described above, we recognize revenue upon shipment of each element, hardware or software, assuming all other basic revenue recognition criteria are met, as both the hardware or software are considered delivered elements and the only undelivered element is post-contract customer support. The revenue from the post-contract customer support is recognized ratably over the term of the related contract.

We account for multiple element arrangements that consist of software or software-related products, including the sale of upgrades to previously sold software and post-contract customer support, in accordance with industry specific accounting guidance for software and software-related transactions. For such transactions, revenue on arrangements that include multiple elements is allocated to each element based on the relative fair value of each element, and fair value is generally determined by vendor-specific objective evidence, or VSOE. If we cannot objectively determine the fair value of any undelivered element included in such multiple-element arrangements, we defer revenue until all elements are delivered and services have been performed, or until fair value can objectively be determined for any remaining undelivered elements. When the fair value of a delivered element has not been established, but fair value exists for the undelivered elements, we use the residual method to recognize revenue if the fair value of all undelivered elements is determinable. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is allocated to the delivered elements and is recognized as revenue. Post-contract support is recognized ratably over the term of the related contract.

Costs incurred for shipping and handling expenses to customers are recorded as cost of revenues. To the extent these amounts are billed to the customer in a sales transaction, we record the shipping and handling fees as revenue.

Allowance for doubtful accounts

We estimate the allowance for doubtful accounts based on an assessment of the collectibility of specific customer accounts. If we determine that a specific customer is unable to meet its financial obligations, we provide a specific allowance for credit losses to reduce the net recognized receivable to the amount we reasonably believe will be collected. Probability of collection is assessed on acustomer-by-customer basis and our historical experience with each customer. Customers are subject to an ongoing credit review process that evaluates the customers’ financial positions. We review and update our estimates for allowance for doubtful accounts on a quarterly basis. Our allowance for doubtful accounts totaled approximately $290,000 and $277,000 at December 31, 2009 and 2008, respectively. Our bad debt expense totaled approximately $59,000, $125,000 and $79,000 for the years ended December 31, 2009, 2008 and 2007, respectively.

Fair value of financial instruments

Our financial instruments consist of cash, cash equivalents, short-term investments, accounts receivable, accounts payable and other accrued liabilities. We believe that the carrying amounts of the financial instruments approximate their respective fair values. When there is no readily available market data, we may make fair value estimates, which may not necessarily represent the amounts that could be realized in a current or future sale of these assets.

Short-term investments

We classify short-term investment asavailable-for-sale securities. We view ouravailable-for-sale-portfolio as available for use in current operations.Available-for-sale securities are recorded at fair value, and we record temporary unrealized holding gains and losses as a separate component of accumulated other comprehensive income. We charge unrealized losses against net earnings when a decline in fair value is determined to beother-than-temporary. We review several factors to determine whether a loss isother-than-temporary. These factors include but are not limited to: (1) the length of time a security is in an unrealized loss position, (2) the extent to which fair value is less than cost, (3) the financial condition and near term prospects of the issuer and (4) our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.

Inventory valuation

We value our inventory at the lower of cost or market. Market is determined based on net realizable value. Cost is determined for raw materials on a“first-in, first-out” basis, for work in process based on actual costs and for finished goods based on standard cost, which approximates actual cost on afirst-in, first-out basis. We reserve for excess and obsolete inventory based on forecasted demand generally over a six to twelve months period and market conditions. Inventory reserves are not reversed and permanently reduce the cost basis of the affected inventory until it is either sold or scrapped.

Impairment of long-lived assets

We review long-lived assets, including equipment, furniture and fixtures, equity investments in privately held companies and intangible assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. An impairment loss would be recognized when estimated undiscounted (and without interest charges) future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. We review for impairment charges on a regular basis.

As of December 31, 2009, we held $4.0 million of investments in privately held companies. We account for $3.5 million of these investments under the cost method. To determine if impairment exists, we monitor each privately held company’s revenue and earnings trends relative to pre-defined milestones and overall business prospects, the general market conditions in its industry and other factors related to its ability to remain in business, such as liquidity and receipt of additional funding.

During the fourth quarter of 2009, we identified certain events and changes in circumstances indicating that the fair value of one of our private company investments had been negatively impacted and determined that the impairment of this investment was other than temporary. As a result, we recorded a $0.5 million impairment loss on this investment to reduce the carrying value to an estimated market value of $0.5 million. The impairment loss was included in other income, net on the Consolidated Statements of Operations for the year ended December 31, 2009.

Warranty provision

We provide a limited warranty for periods of up to three years from the date of delivery against defects in materials and workmanship. If a customer has a defective product, we will either repair the goods or provide replacement products at no charge. We record estimated warranty expenses at the time we recognize the associated product revenues based on our historical rates of return and costs of repair over the preceding36-month period. In addition, we recognize estimated warranty expenses for specific defects at the time those defects are identified.

Share-based compensation

We have in effect share incentive plans under which incentive share options have been granted to employees and non-qualified share options have been granted to employees and non-employee members of the Board of Directors. We also have an employee share purchase plan for all eligible employees. We account for share-based compensation expense based on the estimated fair value of the share option awards as of the grant dates.

We estimate the fair value of share option awards using the Black-Scholes option valuation model, which requires the input of subjective assumptions including the expected share price volatility, the calculation of expected term, and the fair value of the underlying ordinary share on the date of grant, among other inputs. Share compensation expense is recognized on a straight-line basis over each optionee’s requisite service period, which is generally the vesting period.

We base our estimate of expected volatility on a combination of our historical volatility and reported market value data for a group of publicly traded companies, which were selected from market indices that we believe would be indicators of our future share price volatility, after consideration of their size, stage of lifecycle, profitability, growth, risk and return on investment. We calculate the expected term of our options using the simplified method as prescribed by the authoritative guidance. The expected term for newly granted options is approximately 6.25 years.

Share-based compensation expense is recorded net of estimated forfeitures. Forfeitures are estimated at the time of grant and this estimate is revised, if necessary, in subsequent periods. If the actual number of forfeitures differs from that estimated, adjustments may be required to share-based compensation expense in future periods.

Income taxes

To prepare our consolidated financial statements, we estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual tax exposure together with assessing temporary differences resulting from the differing treatment of certain items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet.

We must also make judgments regarding the realizability of deferred tax assets. The carrying value of our net deferred tax asset is based on its belief that it is more likely than not that we will generate sufficient future taxable income in certain jurisdictions to realize these deferred tax assets. A valuation allowance has been established for deferred tax assets which we do not believe meet the “more likely than not” criteria. Our judgments regarding future taxable income may change due to changes in market conditions, changes in tax laws, tax planning strategies or other factors. If our assumptions and consequently our estimates change in the future, the valuation allowances we have established may be increased or decreased, resulting in a respective increase or decrease in income tax expense. Our effective tax rate is highly dependent upon the geographic distribution of our worldwide earnings or losses, the tax regulations and tax holidays in each geographic region, the availability of tax credits and carryforwards, and the effectiveness of its tax planning strategies.

We use a two-step approach to recognizing and measuring uncertain tax positions accounted for in accordance with the guidance on judgments regarding the realizability of deferred taxes. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes.

Total revenue	$	116,044	$	107,701		8

Revenues were $116.0 million for the year ended December 31, 2009 compared to $107.7 million for the year ended December 31, 2008, representing an increase of approximately 8%. This increase in revenues resulted primarily from increased unit sales of approximately 6% and an increase in average selling prices of approximately 2%. The increase in unit sales was primarily due to increases in sales to our tier one customers. The increase in average selling price was primarily due to an increase in revenues from adapter cards and switch systems, which have higher average selling price than ICs, and due to an increase in sales of our QDR products, for which we charge higher average selling prices. The 2009 revenues are not necessarily indicative of future results.

Gross Profit and Margin. Gross profit was $87.4 million for the year ended December 31, 2009 compared to $84.3 million for the year ended December 31, 2008, representing an increase of 4%. As a percentage of revenues, gross margin decreased to 75% in the year ended December 31, 2009 from approximately 78% in the year ended December 31, 2008. The decrease in gross margins was primarily due to a decrease in IC sales for which we normally earn higher margins, and an increase in sales of our switch systems for which we typically earn lower margins. Gross margin for 2009 is not necessarily indicative of future results.

Research and Development. Research and development expenses were $42.2 million for the year ended December 31, 2009 compared to $39.5 million for the year ended December 31, 2008, representing an increase of approximately 7%. The increase was primarily attributable to higher share-based compensation of approximately $1.6 million due to new option grants and atrue-up of estimated forfeitures for share-based compensation expense calculation purposes, increased software related expenses of approximately $946,000 primarily due to software licensing and maintenance, higher new product expenses of approximately $607,000 primarily due to non-recurring engineering charges and increased outsourcing expenses of approximately $253,000 offset by lower salary related expenses of approximately $760,000 primarily associated with temporary salary reductions. We expect that research and development expense will increase in absolute dollars in future periods as we continue to devote resources to develop new products, meet the changing requirements of our customers, expand into new markets and technologies and hire additional personnel.

Sales and Marketing. Sales and marketing expenses were $17.0 million for the year ended December 31, 2009, compared to $15.1 million for the year ended December 31, 2008, representing an increase of approximately 13%. The increase was primarily attributable to higher employee-related expenses of approximately $860,000 associated with increased headcount, an increase in share-based compensation of approximately $528,000 primarily due to new option grants and atrue-up of estimated forfeitures for share-based compensation expense calculation purposes and higher equipment related expenses of approximately $391,000 primarily due to customer product evaluations.

General and Administrative. General and administrative expenses were $9.4 million for the year ended December 31, 2009 compared to $8.4 million for the year ended December 31, 2008, representing an increase of approximately 12%. The increase was primarily due to higher professional services of approximately $664,000, an increase in share-based compensation due to new option grants and atrue-up of estimated forfeitures for share-based compensation expense calculation purposes and higher depreciation expenses of approximately $345,000 offset by a decrease in other expenses of approximately $338,000 primarily associated with the elimination of some benefit programs.

Share-based compensation expense. The following table presents details of total share-based compensation expense that is included in each functional line item in our consolidated statements of income:


	Year Ended December 31,
	2009		2008
	(In thousands)

Cost of goods sold	$	305	$	228
Research and development		6,562		4,936
Sales and marketing		2,125		1,597
General and administrative		1,744		1,175

	$	10,736	$	7,936

The amount of unearned share-based compensation currently estimated to be expensed from 2010 through 2013 related to unvested share-based payment awards at December 31, 2009 is $22.7 million. Of this amount, $9.2 million, $7.9 million, $4.7 million and $0.9 million are currently estimated to be recorded in 2010, 2011, 2012 and 2013, respectively. The weighted-average period over which the unearned share-based compensation is expected to be recognized is approximately 2.71 years. If there are any modifications or cancellations of the underlying unvested awards, we may be required to accelerate, increase or cancel any remaining unearned share-based compensation expense. Future share-based compensation expense and unearned share-based compensation

will increase to the extent that we grant additional equity awards to employees or assume unvested equity awards in connection with acquisitions.

Other Income, net. Other income, net consists of interest earned on cash and cash equivalents and short-term investments, foreign currency exchange gains and losses and impairment of our investments in privately held companies. Other income, net was $518,000 for the year ended December 31, 2009 compared to $3.8 million for the year ended December 31, 2008. The decline is primarily attributable to a decrease of $2.9 million in interest income on investments in securities as a result of lower yields, foreign exchange losses of $36,000 compared to foreign exchange gains of $84,000 in the prior year and a reduction in other income of $151,000.

As of December 31, 209, our investment portfolio included investments of $4.0 million in privately held companies. In the years ended December 31, 2009 and 2008, we determined that the decline in our investment in the preferred stock of one of the privately held companies wasother-than-temporary and recorded impairment charges of $0.5 million and $0.5 million, respectively, to reduce the carrying value of this investment. The additional impairment charge in 2009 is a result of the continued deterioration in one of the privately held company’s financial results and prospective business outlook.

Benefit from (Provision for) Taxes on Income. Our tax expense was $6.4 million for the year ended December 31, 2009 as compared to $2.8 million for the year ended December 31, 2008. The higher tax expense was primarily due to increased taxes related to the utilization of deferred tax assets associated with carryforward losses and research and development costs in Israel.

We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available (positive and negative) evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial performance. We currently expect the Approved Enterprise Tax Holiday in Israel to begin in 2011. As a result, we currently expect to utilize approximately $8.2 million of deferred tax assets associated with our carryforward losses and research and developments costs in Israel during the fiscal year 2010. Our effective tax rate for the fiscal year 2010 may be significantly impacted by the utilization of these deferred tax assets if our actual results differ from our projected taxable income.

Our effective tax rate the year ended December 31, 2009 was 33.1% as compared to 11.1% for the year ended December 31, 2008. The increase in the effective tax rate was primarily due to the fact that in 2008 we recorded a benefit from the recognition of additional deferred tax assets associated with net operating losses expected to be utilized in Israel before the Approved Enterprise Tax Holiday begins.

Revenues. Revenues were $107.7 million for the year ended December 31, 2008 compared to $84.1 million for the year ended December 31, 2007, representing an increase of approximately 28%. This increase in revenues resulted primarily from increased unit sales of approximately 7% and an increase in average selling prices of approximately 19%. The increase in unit sales was primarily due to increases in sales to our tier one customers. The increase in average selling price was primarily due to an increase in revenues from adapter cards and switch systems, which have higher average selling prices and due to an increased revenues from our QDR and DDR products for which we charge higher average selling prices. The 2008 revenues are not necessarily indicative of future results.

Gross Profit and Margin. Gross profit was $84.3 million for the year ended December 31, 2008 compared to $62.7 million for the year ended December 31, 2007, representing an increase of 34%. As a percentage of revenues, gross margin increased to 78% in the year ended December 31, 2008 from approximately 75% in the year ended December 31, 2007. This increase in gross margin was primarily due to a reduction in production costs associated with outsourced labor, raw materials and volume discounts. In addition, part of the gross margin improvement was due to increased sales of QDR and DDR products for which we receive higher margins and to the conclusion of our OCS royalty obligation. During 2008 we incurred royalty expenses of $281,000, compared to $1.5 million in 2007. Gross margin for 2008 is not necessarily indicative of future results.

Research and Development. Research and development expenses were $39.5 million for the year ended December 31, 2008 compared to $24.6 million for the year ended December 31, 2007, representing an increase of approximately 60%. The increase was primarily attributable to higher salary related expenses of approximately $8.2 million associated with increased headcount and merit increases, an increase in share-based compensation of approximately $2.9 million primarily due to new option grants, an increase in new product expenses of approximately $1.5 million primarily due to tape out costs and increased depreciation and amortization of equipment, software and intellectual property of approximately $1.0 million arising from purchases of property, equipment and technology licenses..

Sales and Marketing. Sales and marketing expenses were $15.1 million for the year ended December 31, 2008, compared to $12.7 million for the year ended December 31, 2007, representing an increase of approximately 18%. The increase was primarily attributable to higher salary-related expenses of approximately $1.1 million associated with merit increases, an increase in share-based compensation of approximately $733,000 primarily due to new option grants and an increase in trade show and advertising expenses of approximately $393,000 related to expanding our sales and marketing activities, partially offset by a decrease in external sales commission expenses of approximately $306,000 related to the adoption of a new plan.

General and Administrative. General and administrative expenses were $8.4 million for the year ended December 31, 2008 compared to $6.2 million for the year ended December 31, 2007, representing an increase of approximately 34%. The increase was primarily due to higher employee related expenses of approximately $941,000 associated with increased headcount and merit increases, higher share-based compensation of approximately $631,000 due to new option grants, an increase of approximately $400,000 in professional service fees and an increase of approximately $200,000 in audit fees, which was primarily attributable to SOX section 404 implementation costs.

Other Income, net. Other income, net consists of interest earned on cash and cash equivalents and short-term investments, and foreign currency exchange gains and losses. Other income, net was $3.8 million for the year ended December 31, 2008 compared to $6.0 million for the year ended December 31, 2007. The decline is primarily attributable to a decrease of $2.3 million in interest income on investments in securities as a result of lower yields and a loss of $500,000 recognized as a result of the impairment of our equity investment in a privately-held company.

Benefit from (Provision for) Taxes on Income. Provision for taxes was $2.8 million for the year ended December 31, 2008 as compared to a benefit from taxes on income of $10.5 million for the year ended December 31, 2007. In the year ended December 31, 2007, we released a valuation allowance on certain deferred tax assets of $12.1 million primarily related to net operating losses in Israel expected to be utilized before the Approved Enterprise Tax Holiday begins. In the year ended December 31, 2008, we utilized $1.9 million of the deferred tax assets. The $14.0 million difference between the income from taxes recognized as a result of the release of the valuation allowance of $12.1 million on certain deferred tax assets in 2007 and the tax expense of $1.9 million from the utilization of those deferred tax assets in 2008 was the primary reason for the change in our tax results.

Our effective tax rate for the year ended December 31, 2008 was 11.1% as compared to a tax benefit rate of 42.3% for the year ended December 31, 2007. The increase in the effective tax rate was primarily due to the fact that in 2007 we recorded a benefit of $16.7 million from the release of a valuation allowance on certain deferred tax assets and changes to loss carryforwards.

Liquidity and Capital Resources

Since our inception, we have financed our operations through a combination of sales of equity securities and cash generated by operations. As of December 31, 2009, our principal source of liquidity consisted of cash and cash equivalents of approximately $43.6 million and short-term investments of approximately $166.4 million. We expect that our current cash and cash equivalents and short-term investments and our cash flows from operating activities will be sufficient to fund our operations over the next 12 months after taking into account potential business and technology acquisitions, if any, and expected increases in research and development expenses, including tape out costs, sales and marketing expenses, general and administrative expenses, and capital expenditures to support our infrastructure and growth.

Operating Activities

Net cash generated by our operating activities amounted to approximately $32.8 million in the year ended December 31, 2009. Net cash generated by operating activities was primarily attributable to net income of approximately $12.9 million adjusted for non-cash items including $10.7 million for share-based compensation, approximately $4.1 million for depreciation and amortization and deferred taxes of approximately $3.6 million.

Furthermore, net cash generated by operating activities increased due to a decrease in accounts receivable of approximately $3.0 million as a result of improved linearity related to invoicing during the last quarter of 2009, an increase of approximately $2.3 million in accrued liabilities primarily associated with payroll and an increase of approximately $0.5 million in accounts payable, partially offset by an increase in inventory of approximately $3.0 million due to higher safety stock levels and an increase of approximately $1.0 million in prepaid expenses and other assets.

Net cash generated by our operating activities amounted to approximately $31.0 million in the year ended December 31, 2008. Net cash generated by operating activities was primarily attributable to net income of approximately $22.4 million adjusted for non-cash items of approximately $7.9 million for share-based compensation, $3.6 million for depreciation and amortization, deferred taxes of $1.3 million and an impairment of an equity investment of $0.5 million, offset by gains on short-term investments of $2.3 million. Furthermore, net cash generated by operating activities increased due to an increase of approximately $4.7 million in accrued liabilities primarily associated with payroll and an advance payment from a customer, and an increase of approximately $1.6 million in accounts payable, partially offset by an increase in accounts receivable, net of approximately $6.0 million, an increase in inventory of approximately $1.3 million and an increase of $1.3 million in prepaid expenses and other assets.

Net cash generated by our operating activities amounted to approximately $25.9 million in the year ended December 31, 2007. Net cash generated by operating activities was primarily attributable to net income of approximately $35.6 million adjusted for non-cash items of approximately $3.6 million for share-based compensation and $2.1 million for depreciation and amortization offset by an increase in deferred taxes of $12.1 million and gains on short-term investments of $2.3 million. Furthermore, net cash generated by operating activities increased due to an increase of approximately $4.8 million in accrued liabilities primarily associated with payroll and other payables and an increase of approximately $2.2 million in accounts payable, partially offset by an increase in accounts receivables, net of approximately $7.2 million and an increase in inventory of approximately $1.3 million.

Investing Activities

Net cash used in investing activities was approximately $103.7 million in the year ended December 31, 2009. Cash used in investing activities was primarily attributable to net purchases of short-term investments of $94.8 million, acquisitions of property and equipment of $3.7 million, an equity investment in a privately held company of $3.5 million and an increase in restricted cash deposits of $880,000.

Net cash used in investing activities was approximately $24.2 million in the year ended December 31, 2008. Cash used in investing activities was primarily attributable to net purchases of short-term investments of $16.1 million, acquisitions of property and equipment of $4.5 million, an equity investment in a privately held company of $1.5 million and an increase in restricted cash deposits of $1.4 million.

Net cash used in investing activities was approximately $54.7 million in the year ended December 31, 2007. Cash used in investment activities was primarily attributable to purchases of short-term investments of $151.5 million and purchases of property and equipment of $4.0 million, offset by the maturity and sale of short-term investments of $101.6 million.

Financing Activities

Net cash provided by financing activities was approximately $4.4 million in the year ended December 31, 2009. Cash provided by financing activities was attributable to proceeds from the exercise of share awards of $3.7 million and an excess tax benefit from share-based compensation of $1.2 million, partially offset by principal payments on capital lease obligations of $465,000.

Net cash provided by financing activities was approximately $2.7 million in the year ended December 31, 2008. Cash provided by financing activities was attributable to proceeds from the exercise of share awards of $3.7 million and an excess tax benefit from share-based compensation of $1.0 million, partially offset by principal payments on capital lease obligations of $2.1 million.

Net cash provided by financing activities was approximately $108.8 million in the year ended December 31, 2007. Cash provided by financing activities was attributable to proceeds from the initial public offering of $106.0 million, proceeds from the exercise of share options and warrants of $3.5 million and an excess tax benefit from share-based compensation of $1.5 million, partially offset by principal payments on capital lease obligations of $2.1 million.

Contractual Obligations

The following table summarizes our contractual obligations at December 31, 2009 and the effect those obligations are expected to have on our liquidity and cash flow in future periods:


			Payments Due by Period
			Less Than
Contractual Obligations:	Total		1 Year		1-3 Years		3-5 Years
			(In thousands)

Commitments under capital lease	$	1,009	$	535	$	474	$	—
Non-cancelable operating lease commitments		11,597		4,529		6,755		313
Service commitments		1,186		1,021		165		—
Purchase commitments		17,342		17,342		—		—

Total	$	31,134	$	23,427	$	7,394	$	313

At December 31, 2009, we have no contractual obligations expected to have an effect on our liquidity and cash flow in periods beyond five years.

For purposes of this table, purchase and service obligations for the purchase of goods or services are defined as agreements that are enforceable and legally binding and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. Our purchase orders are based on our current manufacturing needs and are fulfilled by our vendors within relatively short time horizons. In addition, we have purchase orders that represent authorizations to purchase rather than binding agreements. We do not have significant agreements for the purchase of raw materials or other goods specifying minimum quantities or set prices that exceed our expected requirements.

The contractual obligation table excludes our unrecognized tax benefit liabilities because we cannot make a reliable estimate of the timing of cash payment. As of December 31, 2009, our unrecognized tax benefits totaled approximately $1.4 million, which would reduce our income tax expense and effective tax rate, if recognized.

Recent accounting pronouncements

In January 2010, the Financial Accounting Standards Board issued updated guidance related to fair value measurements and disclosures, which requires a reporting entity to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and to describe the reasons for the transfers. In addition, in the reconciliation for fair value measurements using significant unobservable inputs, or Level 3, a reporting entity should disclose separately information about purchases, sales, issuances and settlements (that is, on a gross basis rather than one net number). The updated guidance also requires that an entity should provide fair value measurement disclosures for each class of assets and liabilities and disclosures about the valuation techniques and inputs used to measure fair value for both recurring and non-recurring fair value measurements for Level 2 and Level 3 fair value measurements. The updated guidance is effective for interim or annual financial reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances and settlements in the roll forward activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. We do not expect adoption of the updated guidance to have a material impact on our consolidated results of operations or financial condition.

Off-Balance Sheet Arrangements

As of December 31, 2009, we did not have any off-balance sheet arrangements.

Impact of Currency Exchange Rates

Exchange rate fluctuations could have a material adverse effect on our business, financial condition and results of operations. Our most significant foreign currency exposure is the new Israeli shekel, or NIS. We do not enter into derivatives for speculative or trading purposes. In fiscal year 2009, we used foreign currency forward contracts to hedge a portion of operating expenses denominated in NIS. Our derivative instruments are recorded at fair value in assets or liabilities with final gains or losses recorded in other income, net or as a component of accumulated Other Comprehensive Income and subsequently reclassified into operating expenses in the same period in which the hedged operating expenses are recognized. See Note 5, “Derivatives and Hedging Activities,” of the Notes to Consolidated Financial Statements, included in Part IV, Item 15 of this report.


ITEM 7A —	*QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK*

Interest rate fluctuation risk

We do not have any long-term borrowings. Our investments consist of cash and cash equivalents, short-term deposits, money market funds and interest bearing investments in U.S. government debt securities with an average maturity of less than one year. The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing risk. The Company, by policy, limits the amount of its credit exposure through diversification and restricting its investments to highly rated securities. Individual securities are limited to comprising no more than 5% of the portfolio value at the time of purchase, except U.S Treasury or Agency securities. Highly rated securities are defined as having a minimum Moody or Standard & Poor’s rating of A2 or A respectively. The Company has not experienced any significant losses on its cash equivalents or short-term investments. We do not enter into investments for trading or speculative purposes. Our investments are exposed to market risk due to a fluctuation in interest rates, which may affect our interest income and the fair market value of our investments. Due to the short term nature of our investment portfolio, we do not believe an immediate 2% change in interest rates would have a material effect on the fair market value of our portfolio, and therefore we do not expect our operating results or cash flows to be materially affected to any degree by a sudden change in market interest rates.

Foreign currency exchange risk

We derive all of our revenues in U.S. dollars. The U.S. dollar is our functional and reporting currency in all of our foreign locations. However, a significant portion of our headcount related expenses, consisting principally of salaries and related personnel expenses, are denominated in new Israeli shekels, or NIS. This foreign currency exposure gives rise to market risk associated with exchange rate movements of the U.S. dollar against the NIS. Furthermore, we anticipate that a material portion of our expenses will continue to be denominated in NIS. To the extent the U.S. dollar weakens against the NIS, we will experience a negative impact on our profit margins.

To protect against reductions in value and the volatility of future cash flows caused by changes in foreign currency exchange rates, we have established a balance sheet and anticipated transaction risk management program. Currency forward contracts and natural hedges are generally utilized in this hedging program. We do not enter into forward contracts for trading or speculative purposes. Our hedging program reduces, but does not eliminate the impact of currency exchange rate movements (see Part II, Item 1A, “Risk Factors”). If we were to experience a 10% change in currency exchange rates, the impact on assets and liabilities denominated in currencies other than the U.S. dollar, after taking into account hedges and offsetting positions, would result in a loss before taxes of approximately $111,000 at December 31, 2009. There would also be an impact on future operating expenses denominated in currencies other than the U.S. dollar. At December 31, 2009, approximately $2.8 million of our monthly operating expenses were denominated in NIS. As of December 31, 2009, we had forward contracts in place that hedged future operating expenses of approximately 46.8 million NIS, or approximately $12.4 million based upon the exchange rate as of December 31, 2009. The forward contracts cover future NIS denominated operating expenses expected to occur over the next twelve months. Our derivatives expose us to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. We seek to mitigate such risk by limiting our counterparties to major financial institutions and by spreading the risk across a number of major financial

institutions. However, under current market conditions, failure of one or more of these financial institutions is possible and could result in incurred losses.

Inflation related risk

We believe that the rate of inflation in Israel has not had a material impact on our business to date. Our cost in Israel in U.S. dollar terms will increase if inflation in Israel exceeds the devaluation of the NIS against the U.S. dollar or if the timing of such devaluation lags behind inflation in Israel.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Mellanox Technologies, Ltd.

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of convertible preferred shares and shareholders’ equity (deficit) and of cash flows present fairly, in all material respects, the financial position of Mellanox Technologies, Ltd. and its subsidiaries at December 31, 2009 and December 31, 2008, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2009 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our audits (which were integrated audits in 2009 and 2008). We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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 (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.

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 —	THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Company

Mellanox Technologies, Ltd., an Israeli corporation, and its wholly-owned subsidiary in the United States (collectively referred to as the “Company” or “Mellanox”), were incorporated and commenced operations in March 1999. Mellanox is a supplier of high-performance semiconductor interconnect products for computing, storage and communications applications.

Principles of presentation

The consolidated financial statements include the Company’s accounts as well as those of its wholly owned subsidiary after the elimination of all significant intercompany balances and transactions.

Risks and uncertainties

The Company is subject to all of the risks inherent in a company which operates in the dynamic and competitive semiconductor industry. Significant changes in any of the following areas could have a materially adverse impact on the Company’s financial position and results of operations: unpredictable volume or timing of customer orders; the sales outlook and purchasing patterns of the Company’s customers, based on consumer demands and general economic conditions; loss of one or more of the Company’s customers; decreases in the average selling prices of products or increases in the average cost of finished goods; the availability, pricing and timeliness of delivery of components used in the Company’s products; reliance on a limited number of subcontractors to manufacture, assemble, package and production test the Company’s products; the Company’s ability to successfully develop, introduce and sell new or enhanced products in a timely manner; product obsolescence and the Company’s ability to manage product transitions; and the timing of announcements or introductions of new products by the Company’s competitors.

Additionally, the Company has a significant presence in Israel, including research and development activities, corporate facilities and sales support operations. Uncertainty surrounding the political, economic and military conditions in Israel may directly impact the Company’s financial results.

Use of estimates

The preparation of financial statements in accordance with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of net revenue and expenses in the reporting periods. The Company regularly evaluates estimates and assumptions related to revenue recognition, allowances for doubtful accounts, warranty reserves, inventory reserves, share-based compensation expense, long-term asset valuations, investments, deferred income tax asset valuation allowances, uncertain tax positions, litigation and other loss contingencies. These estimates and assumptions are based on current facts, historical experience and various other factors that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs and expenses that are not readily apparent from other sources. The actual results the Company experiences may differ materially and adversely from the Company’s original estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Cash and cash equivalents

The Company considers all highly liquid investments with a maturity of three months or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist of cash on deposit with banks, money market funds, government agency discount notes and commercial paper.

Restricted cash and deposits

The Company maintains certain cash amounts restricted as to withdrawal or use. At December 31, 2009 the Company maintained a balance of approximately $665,000 that represents tenant’s security deposits restricted due to the tenancy agreement and $2.5 million that represents security deposits restricted due to a foreign exchange management agreement with a bank.

The restricted deposits are presented at their cost, including accrued interest at rates of approximately 0.74% per annum.

Fair value of financial instruments

The Company’s financial instruments consist of cash, cash equivalents, short-term investments, accounts receivable, accounts payable and other accrued liabilities. The Company believes that the carrying amounts of the financial instruments approximate their respective fair values. The Company regularly reviews its investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is temporary include: the length of time and extent to which fair value has been lower than the cost basis; the financial condition, credit quality and near-term prospects of the investee; and whether it is more likely than not that the Company will be required to sell the security prior to any anticipated recovery in fair value. When there is no readily available market data, fair value estimates may be made by the Company, which may not necessarily represent the amounts that could be realized in a current or future sale of these assets.

Derivatives

The Company recognizes derivative instruments as either assets or liabilities and measures those instruments at fair value. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. The Company enters into forward contracts designated as cash flow hedges. For a derivative instrument designated as a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of accumulated other comprehensive income, or OCI, and subsequently reclassified into earnings when the hedged exposure affects earnings.

Short-term investments

The Company’s short-term investments are classified asavailable-for-sale securities and are reported at fair value. Unrealized gains or losses are recorded in shareholders’ equity and included in OCI. The Company views itsavailable-for-sale portfolio as available for use in its current operations. Accordingly, the Company has classified all investments in available for sale securities with readily available markets as short-term, even though the stated maturity date may be one year or more beyond the current balance sheet date, because of the intent and ability to sell these securities prior to maturity to meet liquidity needs or as part of a risk management program.

Concentration of credit risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents, short-term investments and accounts receivable. Cash equivalents and short-term investments balances are maintained with high quality financial institutions, the composition and maturities of which are regularly monitored by management. The Company’s accounts receivable are derived from revenue earned from customers located in North America, Europe and Asia. The Company performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral from its customers. The Company maintains an allowance for doubtful accounts receivable based upon the expected collectibility of accounts receivable. The Company reviews its allowance for doubtful accounts quarterly by assessing individual accounts receivable over a specific aging and amount, and all other balances based on historical collection experience and an economic risk assessment. If the Company determines that a specific customer is unable to meet its financial obligations to the Company, the Company provides an allowance for credit losses to reduce the receivable to the amount management reasonably believes will be collected.

The following table summarizes the revenues from customers (including original equipment manufacturers) in excess of 10% of the total revenues:


	Year Ended December 31,
	2009			2008			2007

Hewlett-Packard		15	%		19	%		19	%
IBM		11	%			*			*
Supermicro Computer Inc		10	%			*			*
Sun Microsystems			*		17	%			*
QLogic			*		11	%		11	%
Voltaire			*			*		15	%
Cisco			*			*		11	%


*		Less than 10%

At December 31, 2009, IBM and Hewlett-Packard accounted for 21% and 13%, respectively, of the Company’s total accounts receivable. At December 31, 2008, Hewlett-Packard, Sun Microsystems and Promate Electronics accounted for 24%, 20% and 13%, respectively, of the Company’s total accounts receivable.

Inventory

Inventory includes finished goods,work-in-process and raw materials. Inventory is stated at the lower of cost (principally standard cost which approximates actual cost on afirst-in, first-out basis) or market value. Reserves for potentially excess and obsolete inventory are made based on management’s analysis of inventory levels and future sales forecasts. Once established, the original cost of the Company’s inventory less the related inventory reserve represents the new cost basis of such products.

Property and equipment

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation and amortization is generally calculated using the straight-line method over the estimated useful lives of the related assets, which is three years for computers, software license rights and other electronic equipment, and seven to fifteen years for office furniture and equipment. Leasehold improvements and assets acquired under capital leases are amortized on a straight-line basis over the term of the lease, or the useful lives of the assets, whichever is shorter. Maintenance and repairs are charged to expense as incurred, and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation or amortization are removed from the accounts and any resulting gain or loss is reflected in the results of operations in the period realized.

Intangible assets

Intangible assets consist of license rights that represent technology which the Company has purchased a perpetual right to use. They are amortized over an estimated useful life of three years using the straight-line method.

Investments

The Company has equity investments in privately-held companies. These investments are recorded at cost because the Company does not have the ability to exercise significant influence over the operating and financial policies of the companies. The investments are included in other long-term assets on the accompanying balance sheets. The Company monitors these investments for impairment by considering available evidence generally including financial, operational and economic data and makes appropriate reductions in carrying values when an impairment is deemed to be other than temporary.

Impairment of long-lived assets

Long-lived assets include equipment, furniture and fixtures, equity investments in privately-held companies and intangible assets. Long-lived assets are reviewed for impairment whenever events or changes in circumstances

indicate that the carrying amount of the assets may not be fully recoverable. If the sum of the expected future cash flows (undiscounted and without interest charges) from the long-lived assets is less than the carrying amount of such assets, an impairment loss would be recognized, and the assets would be written down to their estimated fair values. The Company reviews for possible impairment on a regular basis.

Revenue recognition

The Company recognizes revenue from the sales of products when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred; (3) the price is fixed or determinable; and (4) collection is reasonably assured. The Company uses a binding purchase order or a signed agreement as evidence of an arrangement. Delivery occurs when goods are shipped and title and risk of loss transfer to the customer. The Company’s standard arrangement with its customers typically includesfreight-on-board shipping point and no right of return and no customer acceptance provisions. The customer’s obligation to pay and the payment terms are set at the time of shipment and are not dependent on the subsequent resale of the product. The Company determines whether collectibility is probable on acustomer-by-customer basis. When assessing the probability of collection, the Company considers the number of years the customer has been in business and the history of the Company’s collections. Customers are subject to a credit review process that evaluates the customers’ financial positions and ultimately their ability to pay. If it is determined at the outset of an arrangement that collection is not probable, no product is shipped and no revenue is recognized unless cash is received in advance.

A portion of the Company’s sales are made to distributors under agreements which contain a limited right to return unsold product and price protection provisions. The Company recognizes revenue from these distributors based on the sell-through method using inventory information provided by the distributor. Additionally, the Company maintains accruals and allowances for price protection and cooperative marketing programs. The Company classifies the costs of these programs based on the identifiable benefit received as either a reduction of revenue, a cost of revenues, or an operating expense.

The Company also maintain inventory, or hubbing, arrangements with certain customers. Pursuant to these arrangements the Company delivers products to a customer or a designated third party warehouse based upon the customer’s projected needs, but does not recognize product revenue unless and until the customer reports it has removed the Company’s product from the warehouse to be incorporated into its end products.

The Company recognizes revenue from the sale of hardware products and software bundled with hardware that is essential to the functionality of the hardware in accordance with general revenue recognition accounting guidance. The Company recognizes revenue in accordance with industry specific software accounting guidance for the following types of sales transactions: (i) standalone sales of software products, (ii) sales of software upgrades and (iii) sales of software bundled with hardware not essential to the functionality of the hardware.

For multiple element arrangements, that include a combination of hardware, software and services, such as post-contract customer support, the arrangement consideration is allocated to the separate elements based on fair value. Effective October 1, 2009 the Company adopted authoritative guidance allowing the allocation of the arrangement consideration using the Company’s best estimate of selling price. The change was made prospectively from the beginning of the fiscal year 2009 and did not have a material impact on the Company’s consolidated financial statements, including interim consolidated financial statements reported in the year of adoption. If an arrangement includes undelivered elements that are not essential to the functionality of the delivered elements, the Company defers the fair value or best estimate selling price of the undelivered elements and the residual revenue is allocated to the delivered elements. If the undelivered elements are essential to the functionality of the delivered elements, no revenue is recognized. In the arrangements described above, the Company recognizes revenue upon shipment of each element, hardware or software, assuming all other basic revenue recognition criteria are met, as both the hardware or software are considered delivered elements and only undelivered element is post-contract customer support. The revenue from the post-contract customer support is recognized ratably over the term of the related contract.

The Company accounts for multiple element arrangements that consist of software or software-related products, including the sale of upgrades to previously sold software and post-contract customer support, in accordance with industry specific accounting guidance for software and software-related transactions. For such

transactions, revenue on arrangements that include multiple elements is allocated to each element based on the relative fair value of each element, and fair value is generally determined by vendor-specific objective evidence, or VSOE. If the Company cannot objectively determine the fair value of any undelivered element included in such multiple-element arrangements, the Company defers revenue until all elements are delivered and services have been performed, or until fair value can objectively be determined for any remaining undelivered elements. When the fair value of a delivered element has not been established, but fair value exists for the undelivered elements, the Company uses the residual method to recognize revenue if the fair value of all undelivered elements is determinable. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is allocated to the delivered elements and is recognized as revenue. Post-contract support is recognized ratably over the term of the related contract.

Costs incurred for shipping and handling expenses to customers are recorded as cost of revenues. To the extent these amounts are billed to the customer in a sales transaction, the Company records the shipping and handling fees as revenue.

Product warranty

The Company typically offers a limited warranty for its products for periods up to three years. The Company accrues for estimated returns of defective products at the time revenue is recognized based on prior historical activity. The determination of these accruals requires the Company to make estimates of the frequency and extent of warranty activity and estimated future costs to either replace or repair the products under warranty. If the actual warranty activityand/or repair and replacement costs differ significantly from these estimates, adjustments to record additional cost of revenues may be required in future periods. Changes in the Company’s liability for product warranty during the years ended December 31, 2009 and 2008 are as follows:


	December 31,
	2009			2008
	(In thousands)

Balance, beginning of the period	$	997		$	704
New warranties issued during the period		687			1,013
Reversal of warranty reserves		(426	)		(597	)
Settlements during the period		(356	)		(123	)

Balance, end of the period	$	902		$	997

Research and development

Costs incurred in research and development are charged to operations as incurred, including mask sets. The Company expenses all costs for internally developed patents as incurred. Total research and development operating expenses reported in the Consolidated Statement of Operations for the years ended December 31, 2009, 2008 and 2007 were $42.2 million, $39.5 million and $24.6 million, respectively.

Advertising

Cost related to advertising and promotion of products is charged to sales and marketing expense as incurred. Advertising expense was approximately $26,000, $155,000 and $141,000 for the years ended December 31, 2009, 2008 and 2007, respectively.

Share-based compensation

The Company has in effect share incentive plans under which incentive share options have been granted to employees and non-qualified share options have been granted to employees and non-employee members of the Board of Directors. The Company also has an employee share purchase plan for all eligible employees. The Company accounts for share-based compensation expense based on the estimated fair value of the share option awards as of the grant dates.

The Company estimates the fair value of share option awards using the Black-Scholes option valuation model, which requires the input of subjective assumptions including the expected share price volatility, the calculation of expected term, and the fair value of the underlying common share on the date of grant, among other inputs. Share compensation expense is recognized on a straight-line basis over each optionee’s requisite service period, which is generally the vesting period.

The Company bases its estimate of expected volatility on a combination of historical volatility of the Company stock and reported market value data for a group of publicly traded companies, which were selected from market indices that it believes would be indicators of its future share price volatility, after consideration of their size, stage of lifecycle, profitability, growth, risk and return on investment. The Company calculates the expected term of its options using the simplified method as prescribed by the authoritative guidance. The expected term for newly granted options is approximately 6.25 years.

Share-based compensation expense is recorded net of estimated forfeitures. Forfeitures are estimated at the time of grant and this estimate is revised, if necessary, in subsequent periods. If the actual number of forfeitures differs from the estimate, adjustments may be required to share-based compensation expense in future periods.

Comprehensive income

Accumulated other comprehensive income, net of tax, presented in the accompanying balance sheets consists of the accumulated unrealized gains and losses onavailable-for-sale securities, and the accumulated unrealized gains and losses related to derivative instruments accounted for as cash flow hedges (in thousands).


	December 31,

Accumulated net unrealized gain (loss) on:
Available-for-sale securities	$	184	$	341
Derivative instruments		183		(260	)

Total accumulated other comprehensive income	$	367	$	81

The amount of income tax expense allocated to unrealized gain (loss) onavailable-for-sale securities and hedging activities was not material at December 31, 2009 and 2008.

Foreign currency translation

The Company uses the U.S. dollar as its functional currency. Foreign currency assets and liabilities are remeasured into U.S. dollars at theend-of-period exchange rates except for non-monetary assets and liabilities, which are remeasured at historical exchange rates. Revenue and expenses are remeasured each day at the exchange rate in effect on the day the transaction occurred, except for those expenses related to balance sheet amounts, which are remeasured at historical exchange rates. Gains or losses from foreign currency transactions are included in the Consolidated Statements of Operations as part of “Other income, net.”

Net income per share

Basic and diluted net income per share is computed by dividing the net income for the period by the weighted average number of ordinary shares outstanding during the period. The calculation of diluted net income per share excludes potential ordinary shares if the effect is antidilutive. Potential ordinary shares are comprised of ordinary shares subject to repurchase rights, incremental ordinary shares issuable upon the exercise of share options.

The following table sets forth the computation of basic and diluted net income per share for the periods indicated:


	December 31,
	2009		2008		2007
	(In thousands, except per share data)

Net income	$	12,886	$	22,371	$	35,588

Basic and diluted shares:

Dilutive effect on employee stock option plan		1,301		1,407		2,374

Shares used to compute diluted net income per share		33,400		32,843		30,201

Net income per share — basic	$	0.40	$	0.71	$	1.28

Net income per share — diluted	$	0.39	$	0.68	$	1.18

The following table sets forth potential ordinary shares that are not included in the diluted net income per share above because to do so would be antidilutive for the periods indicated:

Segment reporting

The Company has one reportable segment: the development, manufacturing, marketing and sales of inter-connect semiconductor products.

Income taxes

To prepare the Company’s consolidated financial statements, the Company estimates its income taxes in each of the jurisdictions in which it operates. This process involves estimating the Company’s actual tax exposure together with assessing temporary differences resulting from the differing treatment of certain items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the Company’s consolidated balance sheet.

The Company must also make judgments regarding the realizability of deferred tax assets. The carrying value of the Company’s net deferred tax asset is based on its belief that it is more likely than not that the Company will generate sufficient future taxable income in certain jurisdictions to realize these deferred tax assets. A valuation allowance has been established for deferred tax assets which the Company does not believe meet the “more likely than not” criteria. The Company’s judgments regarding future taxable income may change due to changes in market conditions, changes in tax laws, tax planning strategies or other factors. If the Company’s assumptions and consequently its estimates change in the future, the valuation allowances it has established may be increased or decreased, resulting in a respective increase or decrease in income tax expense. The Company’s effective tax rate is highly dependent upon the geographic distribution of its worldwide earnings or losses, the tax regulations and tax holidays in each geographic region, the availability of tax credits and carryforwards, and the effectiveness of its tax planning strategies.

Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. Income tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first subsequent financial reporting period in which that

threshold is no longer met. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of income as income tax expense.

Recent accounting pronouncements

In January 2010, the Financial Accounting Standards Board issued updated guidance related to fair value measurements and disclosures, which requires a reporting entity to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and to describe the reasons for the transfers. In addition, in the reconciliation for fair value measurements using significant unobservable inputs, or Level 3, a reporting entity should disclose separately information about purchases, sales, issuances and settlements (that is, on a gross basis rather than one net number). The updated guidance also requires that an entity should provide fair value measurement disclosures for each class of assets and liabilities and disclosures about the valuation techniques and inputs used to measure fair value for both recurring and non-recurring fair value measurements for Level 2 and Level 3 fair value measurements. The updated guidance is effective for interim or annual financial reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances and settlements in the roll forward activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. The Company does not expect adoption of the updated guidance to have a material impact on its consolidated results of operations or financial condition.

NOTE 3 —	INVESTMENTS AND FAIR VALUE MEASUREMENTS:

Fair value hierarchy:

Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the authoritative guidance establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the Company to develop its own assumptions. This hierarchy requires companies to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The three levels of the fair value hierarchy are described below:

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 — Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and

Level 3 — Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

The following table represents the fair value hierarchy of the Company’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2009:

The contractual maturities of marketable securities classified as short-term investments at December 31, 2009 and 2008 are due in one year or less. Realized gains upon the sale of marketable securities were approximately $827,000 and $2,303,000 for the years ended December 31, 2009 and December 31, 2008, respectively.

Investments in privately-held companies:

As of December 31, 2009, the Company’s investment portfolio included investments of $4.0 million in privately-held companies. The Company accounts for $3.5 million of these investments under the cost method. To determine if impairment exists, the Company monitors the portfolio companies’ revenue and earnings trends relative to pre-defined milestones and overall business prospects, the general market conditions in its industry and other factors related to its ability to remain in business, such as liquidity and receipt of additional funding.

During the fourth quarter of 2009, the Company identified certain events and changes in circumstances indicating that the fair value of the investments in one of the portfolio companies had been negatively impacted and determined that the impairment of this investment was other than temporary. In determining whether a decline in value of its investment has occurred and is other than temporary, an assessment was made by considering available evidence, including the general market conditions in the company’s industry, its financial condition, near-term prospects and subsequent rounds of financing. The valuation also takes into account the company’s capital structure, liquidation preferences for its capital and other economic variables as well as other inputs that require management judgment. As a result of the assessment, the Company recorded a $0.5 million impairment loss on this investment to reduce the carrying value to its estimated market value. The impairment loss was included in other income, net, on the Consolidated Statements of Operations for the year ended December 31, 2009. The carrying value of the Company’s investment was $0.5 million and is classified within other long term assets on the Company’s Consolidated Balance Sheets as of December 31, 2009.

Amortization expense of intangible assets totaled approximately $179,000, $165,000 and $67,000 for the years ended December 31, 2009, 2008 and 2007, respectively. Amortization expense is expected to be $191,000 for each of the years ended December 31, 2010 and 2011, and $46,000 for the year ended December 31, 2012. The intangible assets are expected to be fully amortized in 2012.


NOTE 5 —	DERIVATIVES AND HEDGING ACTIVITIES:

The Company uses derivative instruments primarily to manage exposures to foreign currency. The company enters into forward contracts to manage its exposure to changes in the exchange rate of the New Israeli Shekel (“NIS”) against the U.S. dollar. The Company’s primary objective in entering these arrangements is to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. The program is not designated for trading or speculative purposes. The Company’s forward contracts expose the Company to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. The Company seeks to mitigate such risk by limiting its counterparties to major financial institutions and by spreading the risk across a number of major financial institutions. In addition, the potential risk of loss with any one counterparty resulting from this type of credit risk is monitored on an ongoing basis.

The Company uses forward contracts designated as cash flow hedges to hedge a substantial portion of forecasted operating expenses in NIS. The gain or loss on the effective portion of a cash flow hedge is initially reported as a component of OCI and subsequently reclassified into operating expenses in the same period in which the hedged operating expenses are recognized, or reclassified into other income, net, if the hedged transaction

becomes probable of not occurring. Any gain or loss after a hedge is de-designated because it is no longer probable of occurring or related to an ineffective portion of a hedge, as well as any amount excluded from the Company’s hedge effectiveness, is recognized as other income, net immediately. The net gains or losses relating to ineffectiveness were not material in the year ended December 31, 2009. As of December 31, 2009, the Company had forward contracts in place that hedged future operating expenses of approximately 46.8 million NIS, or approximately $12.4 million based upon the exchange rate as of December 31, 2009. The forward contracts cover future NIS denominated operating expenses expected to occur over the next twelve months.

The Company does not use derivative financial instruments for purposes other than cash flow hedges.

Fair value of Derivative Contracts

The fair value of derivative contracts as of December 31, 2009 and December 31, 2008 was as follows:


	Derivative Assets Reported in				Derivative Liabilities Reported in

Foreign exchange contracts designated as cash flow hedges relate primarily to operating expenses and the associated gains and losses are expected to be recorded in operating expenses when reclassed out of OCI. The Company expects to realize the accumulated OCI balance related to foreign exchange contracts within the next twelve months.

NOTE 6 —	EMPLOYEE BENEFIT PLANS:

The Company adopted a 401(k) Profit Sharing Plan and Trust (the “401(k) Plan”) effective January 2000, which is intended to qualify under Section 401(k) of the Internal Revenue Code. The 401(k) Plan allows eligible employees in the United States to voluntarily contribute a portion of their pre-tax salary, subject to a maximum limit of $16,500 for the year ended December 31, 2009, subject to certain limitations. The Company matches employee

contributions of up to 4% of their annual base salaries. The total expenses for these contributions were approximately $228,000 and $180,000 for the years ended December 31, 2009 and 2008, respectively.

Under Israeli law, the Company is required to make severance payments to its retired or dismissed Israeli employees and Israeli employees leaving its employment in certain other circumstances. The severance pay liability of the Company to its Israeli employees is calculated based on the salary of each employee multiplied by the number of years of such employee’s employment and is presented in the Company’s balance sheet in long-term liabilities, as if it was payable at each balance sheet date on an undiscounted basis. This liability is partially funded by the purchase of insurance policies in the name of the employees. The surrender value of the insurance policies is presented in long-term assets. Severance pay expenses for years ended December 31, 2009, 2008 and 2007 were approximately $419,000, $799,000 and $194,000, respectively, and included gains of $503,000, losses of $277,000 and gains of $322,000, respectively, from investments in severance assets. The severance pay detail is as follows:

NOTE 7 —	COMMITMENTS AND CONTINGENCIES:

Leases

The Company leases office space and motor vehicles under operating leases with various expiration dates through 2014. Rent expense was approximately $2.1 million, $1.8 million and $1.3 million for the years ended December 31, 2009, 2008 and 2007 respectively. The terms of the facility lease provide for rental payments on a graduated scale. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid.

The Company has entered into capital lease agreements for electronic design automation software. The total amount of assets under capital lease agreements within “Property and equipment, net” was approximately $3.3 million and $5.7 million for the years ended December 31, 2009 and 2008, respectively. At December 31, 2009, future minimum lease payments under non-cancelable operating and capital leases totaled approximately $12.6 million. For the years ended December 31, 2009 and 2008, the accumulated amortization for assets under capital lease agreements totaled approximately $2.3 million and $3.0 million, respectively. At December 31, 2009, future minimum lease payments under non-cancelable operating and capital leases, and future minimum sublease rental receipts under non-cancelable operating leases are as follows:

Service commitments

At December 31, 2009, the Company had non-cancelable service commitments of $1.2 million, $1.0 million of which is expected to be paid in 2010 and $165,000 in 2011 and beyond.

Purchase commitments

At December 31, 2009, the Company had non-cancelable purchase commitments of $17.3 million expected to be paid within one year. At December 31, 2009, the Company had no non-cancelable purchase commitments with suppliers beyond one year.

Royalty obligations

Prior to 2003, the Company received funds totaling $600,000 from the Binational Industrial Research and Development Foundation (the “BIRD Foundation”). As a result, the Company is obligated to pay the BIRD Foundation royalties from sales of products in the research and development of which the BIRD Foundation participated by way of grants. Royalty rates range from 1.45% to 2.95% of “qualifying” product revenue. Since the length of time of repayment has exceeded four years, the grant amount to be repaid has increased to $900,000. However, should the Company decide to discontinue sales of the “qualifying” products, no additional amounts are required to be paid. At December 31, 2009, the Company had repaid and accrued approximately $553,000 to the BIRD Foundation, and the contingent liability in respect of royalties payable is approximately $347,000.

The Company has also received and paid off approximately $2.8 million in OCS funding. The terms of the OCS grants require the Company to pay the OCS royalties if products are developed using the OCS funding. For those products that are developed and ultimately result in revenues to the Company, royalties will be paid to the OCS at the rate of 4% of net sales of such OCS-funded products. As of January 1, 2007, that rate increased to 4.5%. Grants from the OCS are repaid with an annual interest rate based on the LIBOR interest rate on the date of payment. The repayment of OCS grants is contingent on future sales of products developed with the support of such grants and the Company has no obligation to refund these grants if future sales are not generated.

The terms of OCS grants generally prohibit the manufacture of products developed with OCS funding outside of Israel without the prior consent of the OCS. The OCS has approved the manufacture outside of Israel by the Company of its IC products, subject to an undertaking by the Company to pay the OCS royalties on the sales of the Company’s OCS-supported products until such time as the total royalties paid equal 120% of the amount of OCS grants.

The Company had concluded all its obligations in respect of royalties payable to the OCS in 2008.

Under applicable Israeli law, OCS consent is also required for the Company to transfer technologies developed with OCS funding to third parties in Israel. Transfer of OCS-funded technologies outside of Israel is permitted with the approval of the OCS and in accordance with the restrictions and payment obligations set forth under Israeli law. Israeli law further specifies that both the transfer of know-how as well as the transfer of intellectual property rights in such know-how are subject to the same restrictions. These restrictions do not apply to exports of products from Israel or the sale of products developed with these technologies. The Company does not anticipate the need to transfer any of its intellectual property rights outside of Israel at this time.

Contingencies

The Company is not currently subject to any material legal proceedings. The Company may, from time to time, become a party to various legal proceedings arising in the ordinary course of business. The Company may also be indirectly affected by administrative or court proceedings or actions in which the Company is not involved but which have general applicability to the semiconductor industry.

(1)		The Series C convertible preferred shares were issued in exchange for software.

Prior to the conversion of the Company’s preferred shares into ordinary shares upon the closing of the Company’s initial public offering on February 7, 2007, the holders of the Company’s preferred shares had various rights and preferences as follows:

Voting

The holders ofSeries A-1 convertible preferred shares(“Series A-1”),Series B-1 convertible preferred shares(“Series B-1”), Series C convertible preferred shares (“Series C”) and Series D mandatorily redeemable convertible preferred shares (“Series D”) had voting rights based on the number of ordinary shares into which theSeries A-1,Series B-1, Series C and Series D shares were convertible. The holders ofSeries A-2 convertible preferred shares(“Series A-2” and together withSeries A-1, “Series A”) andSeries B-2 convertible preferred shares(“Series B-2” and together withSeries B-1, “Series B”) had no voting rights. Certain voting rights of the holders of the preferred shares applied with respect to certain matters, as specified in the Company’s amended and restated articles of association in effect prior to the initial public offering. The Company had to obtain approval from the holders of a majority of theSeries A-1,Series B-1, Series C and Series D shares, voting together as a single class, to increase the authorized number of directors (unless such increase is approved by at least 75% of the board of directors) or effect a merger, consolidation or sale of assets where the existing shareholders retain less than 50% of the voting power of the surviving entity. The Company had to obtain approval from the holders of 67% of theSeries A-1,Series B-1 and Series C, voting together as a single class, to: increase the number of authorized preferred shares; authorize, create or issue any securities senior to the preferred shares; alter the amended and restated articles of association in a manner that adversely affected the preferred shares; repurchase or redeem any ordinary shares other than in connection with termination of employment; or pay any dividends on the ordinary shares. The Company had to obtain approval from the holders of a majority of the Series D shares to: change the authorized number of directors; increase or decrease the number of authorized ordinary shares or preferred shares; authorize, create or issue any securities on parity with or senior to the Series D shares; alter the amended and restated articles of association; alter the rights, preferences, privileges or restrictions of the Series D shares in a manner that adversely affected such shares; repurchase or redeem any ordinary shares or preferred shares other than in connection with termination of employment or the redemption of the Series D shares in accordance with the amended and restated articles of association; pay any dividends on the ordinary shares or preferred shares; or effect a merger, consolidation or sale of assets where the existing shareholders retain less than 50% of the voting power of the surviving entity.

Dividends

The holders of Series D shares were entitled to receive dividends in preference to any dividend on the Series A, Series B, Series C and ordinary shares at an annual rate equal to 7% of their original issue price. Thereafter, holders of Series A, Series B and Series C shares were entitled to receive dividends in preference to any dividend on the ordinary shares at an annual rate equal to 7% of their respective original issue prices. Such dividends on the Series A, Series B, Series C and Series D shares were non-cumulative and would be paid only when and if declared. After payment of such dividends to the holders of Series A, Series B and Series C shares, any additional dividends declared would be distributed among all holders of Series D and ordinary shares in proportion to the number of ordinary shares that would be held by each such holder if the Series D shares were converted into ordinary shares. No dividends on Series A, Series B, Series C or Series D or ordinary shares had been declared by the board from inception through December 31, 2006.

Liquidation

Upon liquidation or dissolution of the Company, the holders of the Series D shares would be entitled to receive, prior and in preference to any other holders of shares of the Company, an amount per share equal to one and a half times their original issue price (subject to adjustment in respect of share splits, share dividends and like events), plus all declared but unpaid dividends. Then, the holders of the Series A, Series B, Series C and Series D shares would be entitled to receive an amount per share equal to one times their respective original issue price (subject to adjustment in respect of share splits, share dividends and like events), plus all declared but unpaid dividends. The remaining assets and funds legally available for distribution, if any, would be distributed equally to the holders of the Series A, Series B and Series C shares (on an as-converted basis) and ordinary shares until such time as the holders of the Series A, Series B and Series C shares received an amount per share equal to two times their respective original issue prices (subject to adjustment in respect of share splits, share dividends and like events).

Conversion

Each share of Series A, Series B, Series C and Series D was, at the option of the holder of such share, at any time, convertible into one ordinary share, subject to certain adjustments. The outstanding Series A, Series B, Series C and Series D shares would automatically convert into ordinary shares upon the closing of an underwritten public offering with at least $15 million (in the case of the Series A) and $50 million (in the case of the Series B, Series C and Series D) in net proceeds to the Company, and an offering price per share of at least $5.25 (in the case of the Series A) and $28.93 (in the case of the Series B, Series C and Series D), subject in each case to adjustments for share splits, dividends, reclassifications and the like (a “Qualified IPO”). In addition, the Series A, Series B, Series C and Series D would be automatically converted into ordinary shares upon the affirmative vote of the holders of the majority of the issued and outstanding Series D shares (including the vote of Bessemer Venture Partners for so long as Bessemer Venture Partners continues to hold at least 324,285 Series D shares) in connection with the consummation of an underwritten public offering in which the offering price per share is less than $28.93 (subject to adjustments for share splits, dividends, reclassifications and the like) or in connection with a liquidation transaction, as described in the Company’s amended and restated articles of association. In addition, theSeries A-2 andSeries B-2 shares would be converted toSeries A-1 andSeries B-1 shares upon the transfer of such shares to a bona fide purchaser unaffiliated with the transferor or immediately prior to the consummation of a Qualified IPO.

Anti-dilution adjustments

The Series D would be protected against dilution if the Company issued any capital shares or securities convertible into or exchangeable for capital shares at a price per share less than the price per share paid by the holders of the Series D, in which case such adjustment would be on a full-ratchet basis. In addition, the per share conversion rate of the Series D was determined by multiplying $11.57, as adjusted for share splits, by 2.5, and dividing by the $17.00 price per share paid in the offering. Therefore, the holders of the Series D received 1.7011 ordinary shares for each share of Series D converted in connection with the initial public offering. The adjustment to the Series D conversion price did not trigger any other antidilution adjustments, nor did it trigger any rights of first offer or other preemptive rights.

Redemption

The Company’sSeries A-1,Series A-2,Series B-1,Series B-2 and Series C preferred shares were considered redeemable for accounting purposes. The Company initially recorded theSeries A-1,Series A-2,Series B-1,Series B-2 and Series C preferred shares at their fair values on the dates of issuance, net of issuance costs. A deemed liquidation event could have occurred as a result of the sale of all or substantially all of the assets of the Company or any acquisition of the Company by another entity by means of a merger or consolidation in which the shareholders of the Company did not hold at least 50% of the voting power of the surviving entity or its parent. Because the deemed redemption event was outside the control of the Company, all preferred shares have been presented outside of permanent equity in accordance with EITF Topic D-98,“Classification and Measurement of Redeemable Securities.”Further, the Company has not adjusted the carrying values of theSeries A-1,Series A-2,Series B-1,Series B-2 and Series C preferred shares to the redemption value of such shares, because it was uncertain whether or when a redemption event would occur.

The Series D shares were required to be redeemed by the Company upon the request of holders of a majority of the outstanding Series D shares at any time after September 30, 2007. The shares were required to be redeemed by the Company at a price equal to the original issue price and declared but unpaid dividends. The difference between the carrying value of the Series D shares and their redemption value was accreted using the effective interest method through the initial public offering.


NOTE 9 —	ORDINARY SHARES:

On February 1, 2007, the Company’s amended and restated articles of association authorized the Company to issue 137,142,857 ordinary shares of nominal value NIS 0.0175 each. A portion of the shares sold prior to the initial public offering were subject to a right of repurchase by the Company subject to vesting, which is generally over a four-year period from the earlier of issuance date or employee hire date, as applicable, until vesting is complete.


NOTE 10 —	SHARE OPTION PLANS:

The Company has four option plans: the 1999 United States Equity Incentive Plan, 1999 Israeli Share Option Plan, 2003 Israeli Share Option Plan (collectively, the “Prior Plans”) and the 2006 Global Share Incentive Plan (the “Global Plan”).

The Global Plan was adopted by the board of directors in October 2006 and approved by shareholders in December 2006. The Global Plan replaces the Prior Plans and became effective on February 6, 2007. The Company has authorized for issuance under the Global Plan an aggregate of 3,428,571 ordinary shares, plus the number of ordinary shares available for issuance under the Prior Plans that are not subject to outstanding options, as of the effective date of the Global Plan. In addition, the number of ordinary shares reserved for issuance under the Global Plan will increase automatically on the first day of each fiscal year, beginning in 2008, by a number of ordinary shares equal to the lower of: (i) 2% of total number of ordinary shares outstanding on a fully diluted basis on the date of the increase, (ii) 685,714 ordinary shares, or (iii) a smaller number determined by the board of directors. In any event, the maximum aggregate number of ordinary shares that may be issued or transferred under the Global Plan during the term of the Global Plan may in no event exceed 15,474,018 ordinary shares. The Global Plan was automatically increased by 685,714, 685,714 and 680,513 shares on January 1, 2010, 2009 and 2008, respectively.

The following table summarizes the activity under the Plans, the Global Plan and other share-based arrangements:

$0.18 - $20.02		6,403,679		7.44	$	8.38		2,698,959	$	5.91

Of the 2,698,959 options exercisable at December 31, 2009, 2,658,668 options were fully vested and 40,291 were unvested but exercisable by U.S. employees under the 1999 Plan.

The total pretax intrinsic value of options exercised in 2009 was $9.0 million. This intrinsic value represents the difference between the fair market value of the Company’s ordinary shares on the date of exercise and the exercise price of each option. Based on the closing price of the Company’s ordinary shares of $18.89 on December 31, 2009, the total pretax intrinsic value of all outstanding options was $67.3 million. The total pretax intrinsic value of exercisable options at December 31, 2009 was $35.0 million.

The Company’s Employee Share Purchase Plan, or ESPP, was adopted by the board of directors in November 2006 and approved by shareholders in December 2006, and became effective immediately prior to the Company’s initial public offering on February 7, 2007. The ESPP is designed to allow eligible employees to purchase the Company’s ordinary shares, at semi-annual intervals, with their accumulated payroll deductions. A participant may contribute up to 15% of his or her base compensation through payroll deductions, and the accumulated deductions will be applied to the purchase of shares on the purchase date, which is the last trading day of the offering period. The purchase price per share will be equal to 85% of the fair market value per share on the start date of the offering period in which the participant is enrolled or, if lower, 85% of the fair market value per share on the purchase date. 571,428 shares have been initially reserved for issuance pursuant to purchase rights under the ESPP. In addition, the number of ordinary shares reserved under the Company’s ESPP will increase automatically on the first day of each fiscal year during the term, beginning in 2009, by a number of ordinary shares equal to the lower of (i) 0.5% of the total number of ordinary shares outstanding on a fully diluted basis on the date of the increase, (ii) 171,428 shares or (iii) a smaller number of shares as determined by the board of directors. In any event, the maximum aggregate number of ordinary shares that may be issued over the term of the ESPP may in no event exceed 2,114,285 shares. In addition, no participant in the ESPP may be issued or transferred more than $25,000 worth of ordinary shares pursuant to purchase rights under the ESPP per calendar year. During the years ended December 31, 2009 and 2008, 206,529 and 160,352 shares, respectively, were issued under this plan at weighted average per share prices of $6.96 and $11.42, respectively. At December 31, 2009, 142,414 shares were available for future issuance under the ESPP.

Share option exchange program

In April 2009, the Company completed an offer to exchange certain employee share options issued under the Global Plan. The option exchange program allowed eligible employees and contractors of the Company to exchange their outstanding options that had an exercise price greater than $13.65 per share for a lesser number of options calculated in accordance with exchange ratios. The ratios were determined using the Black-Scholes option pricing model based on, among other things, the closing price of the Company’s ordinary shares as quoted on The Nasdaq Global Select Market on March 16, 2009 and the exercise prices of the options eligible for exchange. The exchange ratios used were as follows:


			Shares Subject to
	Shares Subject to Option		Replacement Option
Exercise Price Range	Surrendered		Granted

$13.66 to $16.99		1.10		1
$17.00 and above		1.21		1

Pursuant to the program, 255 eligible participants tendered, and the Company accepted for exchange, options to purchase an aggregate of 2,340,334 ordinary shares, representing approximately 96% of eligible options. In exchange, the Company granted 1,983,797 options with an exercise price of $10.23 per share, which was the closing price of the Company’s ordinary shares as reported by the Nasdaq Global Select Market on April 22, 2009.

For options originally granted in 2007, the replacement options granted in the option exchange program vest as follows: one-third (1/3) of the options replaced vest and become exercisable on the one-year anniversary of the replacement grant date, with the remaining shares vesting and becoming exercisable in equal monthly increments over the 24 months following the first anniversary of the replacement grant date. For options originally granted in 2008, the replacement options vest as follows: one-fourth (1/4) of the shares subject to each replacement option vest and become exercisable on the one-year anniversary of the replacement grant date, with the remaining shares vesting and becoming exercisable in equal monthly increments over the 36 months following the first year anniversary of the replacement grant date.

A modification charge resulting from the share option exchange program was immaterial.

Share-based compensation

The Company has in effect share incentive plans under which incentive share options have been granted to employees and non-qualified share options have been granted to employees and non-employee members of the Board of Directors. The Company also has an employee share purchase plan for all eligible employees. Effective January 1, 2006, the Company accounts for share-based compensation expense based on the estimated fair value of the share option awards as of the grant dates.

The following weighted average assumptions are used to value share options granted in connection with the Company’s share incentive plans for the years ended December 31, 2009, 2008 and 2007:


	Employee Stock Options						Employee Stock Purchase Plan

The Company records net deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence,

including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial performance.

At December 31, 2009, the Company had foreign net operating loss carryforwards of approximately $35.7 million. The foreign net operating losses have no expiration date.

The reconciliation of the statutory federal income tax rate to the Company’s effective tax rate is as follows:


	Year Ended December 31,
	2009			2008			2007

Tax at statutory rate		34.0	%		34.0	%		34.0	%

The Company calculates the pool of excess tax benefits available to absorb tax deficiencies recognized using the method under which each award grant is tracked on anemployee-by-employee basis andgrant-by-grant basis to determine if there is a tax benefit situation or tax deficiency situation for such award. The Company then compares the fair value expense to the tax deduction received for each grant and aggregates the benefits and deficiencies to determine whether there is a hypothetical additional paid in capital (APIC) pool (net tax benefit situation). For the years ended December 31, 2009 and 2008, the Company recognized a tax benefit to APIC of $1.2 and $2.9 million, respectively.

The Company’s operations in Israel have been granted “Approved Enterprise” status by the Investment Center in the Israeli Ministry of Industry Trade and Labor, which makes the Company eligible for tax benefits under the Israeli Law for Encouragement of Capital Investments, 1959. Under the terms of the Approved Enterprise program, income that is attributable to the Company’s operations in Yokneam, Israel, will be exempt from income tax for a period of ten years commencing when the Company first generates taxable income (after setting off its losses from prior years). Currently, the Company expects the Approved Enterprise Tax Holiday associated with its Yokneam operations to begin in 2011 and expire in 2020. Income that is attributable to the Company’s operations in Tel Aviv, Israel, will be exempt from income tax for a period of two years commencing when the Company first generates taxable income (after setting off its losses from prior years), and will be subject to a reduced income tax rate (generally10-25%, depending on the percentage of foreign investment in the Company) for the following five to eight years. Currently, the Company expects the Approved Enterprise Tax Holiday associated with its Tel Aviv operations to begin in 2011 and expire between the years 2015 and 2018.

As a multinational corporation, the Company conducts business in many countries and is subject to taxation in many jurisdictions. The taxation of the Company’s business is subject to the application of multiple and sometimes conflicting tax laws and regulations as well as multinational tax conventions. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws themselves are subject to change as a result of changes in fiscal policy, changes in legislation and the evolution of regulations and court rulings. Consequently, taxing authorities may impose tax assessments or judgments against the Company that could materially impact its tax liabilityand/or its effective income tax rate.

The Company uses a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. Upon implementation of this guidance, the Company recognized no material adjustment to the

January 1, 2007 accumulated deficit balance. As of December 31, 2009 and 2008, the unrecognized tax benefits totaled approximately $1.4 million and $1.7 million, respectively, which would reduce the Company’s income tax expense and effective tax rate, if recognized.

The following summarizes the activity related to the Company’s unrecognized tax benefits:


	Year Ended December 31,
	2009			2008
	(In thousands)

Gross unrecognized tax benefits, beginning of the period	$	1,714		$	1,139

Increases in tax positions for current year		393			859
Decreases in tax positions for current year		—			—

Gross unrecognized tax benefits, end of the period	$	1,442		$	1,714

It is the Company’s policy to classify accrued interest and penalties as part of the accrued unrecognized tax benefits liability and record the expense in the provision for income taxes. For the years ended December 31, 2009 and 2008, the amount of accrued interest or penalties related to unrecognized tax benefit totaled $67,000 and $20,000, respectively. For unrecognized tax benefits that existed at December 31, 2009, the Company does not anticipate any significant changes within the next twelve months.

The Company files income tax returns in the U.S. federal jurisdictions, and various states and foreign jurisdictions. The 2005 through 2009 tax years are open and may be subject to potential examination in one or more jurisdictions. The Company is not currently under federal, state or foreign income tax examination.

Undistributed earnings of the Company’s subsidiary, Mellanox Technologies, Inc., are indefinitely reinvested in the respective operations. If its earnings were to be repatriated, the Company would be subject to additional tax.
