Business Overview
PDF Solutions is a leading provider of infrastructure technologies and services to lower the cost of integrated circuit (“IC”) design and manufacturing, enhance time to market, and improve profitability by addressing design and manufacturing interactions from technology development and product design to initial process ramps to mature manufacturing operations. Our technologies and services target the entire “process life cycle,” which is the term we have coined for the time from technology development and the design of an IC through volume manufacturing of that IC. Our solutions combine proprietary software, physical intellectual property (“IP”) in the form of cell libraries for IC designs, test chips, an electrical wafer test system, proven methodologies, and professional services. We analyze yield loss mechanisms to identify, quantify, and correct the issues that cause yield loss. Our analysis drives IC design and manufacturing improvements to enable our customers to optimize the technology development process, to increase initial yield when an IC design first enters a manufacturing line, to increase the rate at which yield improves, and to minimize excursions and process variability that cause yield loss throughout mass production. The result of successfully implementing our solutions is the creation of value that can be measured based on improvements to our customers’ actual yield. Through our gainshare performance incentives component, we have aligned our financial interests with the yield and performance improvements realized by our customers, and we receive revenue based on this value. Our technologies and services have been sold to leading integrated device manufacturers, fabless semiconductor companies, and foundries.
The key benefits of our solutions to our customers are:
Faster Time to Market.
Our solutions are designed to accelerate our customers’ time-to-market and increase product profitability. Our solutions, which can predict and improve product yield even before IC product design is complete, transform the traditional design-to-silicon sequence into a primarily concurrent process, thereby shortening our customers’ time-to-market. Systematically incorporating knowledge of the integration of the design and manufacturing processes into our software modules and physical IP enables our customers to introduce products with higher initial yields faster. Our solutions are designed to decrease design and process iterations and reduce our customers’ up-front costs, and thus provide our customers with early-mover advantages such as increased market share and higher selling prices.
Faster Time to Volume.
After achieving higher initial yields and faster time-to-market, our solutions are designed to enable our customers to isolate and eliminate remaining yield issues to achieve cost efficient volume manufacturing. Once a manufacturing process has been modeled using our solutions, our customers are able to diagnose problems and simulate potential corrections more quickly than using traditional methods. In addition, if process changes are required, improvements can be verified more quickly using our technology than using traditional methods. Our solutions thus enable our customers to quickly reach cost efficient volume, so that they are able to increase margins, improve their competitive position, and capture higher market share.
Increased Manufacturing Efficiencies.
Our solutions for product design, product introduction, yield ramp, and process control are designed to allow our customers to achieve a higher yield at mass production and therefore a lower cost of goods sold. In addition, our solutions, which also include fault detection and classification (“FDC”) software, are designed to provide our customers with the ability to proactively monitor process health to avoid potential yield problems.
3
Our long-term business objective is to maximize IC yield by providing the industry standard in technologies and services for the Process Life Cycle. To achieve this objective, we intend to:
Extend Our Technology Leadership Position.
We intend to extend our technology leadership position by leveraging our experienced engineering staff and codifying the knowledge that we acquire in our solution implementations. For example, we continue to expand and develop new technology that leverages our Characterization Vehicle
®
(CV
®
) methodology to embed test structures on product wafers. This provides valuable insight regarding product yield loss during mass production with minimal or no increase in test time and non-product wafers. In addition, we selectively acquire complementary businesses and technologies to increase the scope of our solutions.
Leverage Our Gainshare Performance Incentives Business Model.
We intend to continue expanding the gainshare performance incentives component of our customer contracts. We believe this approach allows us to form collaborative and longer-term relationships with our customers by aligning our financial success with that of our customers. Working closely with our customers on their core technologies that implement our solutions, with a common focus on their business results, provides direct and real-time feedback for continual improvement of our solutions. We believe that we will generate expanded relationships with customers that engage us on terms that include a significant gainshare performance incentive component.
Focus on Key IC Product Segments and High-Growth Adjacent Markets.
We intend to focus our solutions on high-volume, high-growth IC product segments such as system-on-a-chip, memory, CMOS image sensor, and high-performance central processing units. As a result, we will continue to expand our solutions for technology drivers such as low-k dielectrics, high-k metal gates, immersion lithography, double patterning, SOI, copper, and 300mm wafer fabs, which are all still somewhat new or are relatively complex manufacturing technologies. We believe that these product segments are particularly attractive because they include complex IC design and manufacturing processes where processed silicon is costly and yield is critical. In addition, we have expanded our efforts to penetrate relatively new and potentially high-growth adjacent markets, such as photovoltaic and LED manufacturing, and we are leveraging our yield management system and FDC technology to create products that meet the needs of these markets.
Expand Strategic Relationships.
We intend to continue to extend and enhance our relationships with companies at various stages of the design-to-silicon process, such as process licensors, manufacturing and test equipment vendors, electronic design automation vendors, silicon IP providers, semiconductor foundries, and contract test and assembly houses.
Industry Background
Rapid technological innovation, with increasingly shorter product life cycles, now fuels the economic growth of the semiconductor industry. IC companies historically ramped production slowly, produced at high volume once products gained market acceptance, and slowly reduced production volume when price and demand started to decrease near the end of the products’ life cycles. Now, companies often need to be the first to market and the first to sell the most volume when a product is first introduced so that they have performance and pricing advantages over their competition, or else they lose market opportunity and revenue. Increased IC complexity and compressed product lifecycles create significant challenges to achieve competitive initial yields and optimized performance. For example, it is not uncommon for an initial manufacturing run to yield only 20%, which means that 80% of the ICs produced are wasted. Yield improvement and performance optimization are critical drivers of IC companies’ financial results because they typically lead to cost reduction and revenue generation concurrently, causing a leveraged effect on profitability.
Technology and Intellectual Property Protection
We have developed proprietary technologies for yield simulation, analysis, loss detection, and improvement. The foundation for many of our solutions is our CV infrastructure (“CV
i
”) that enables our customers to characterize the manufacturing process, and establish fail-rate information needed to calibrate manufacturing yield models, prioritize yield improvement activities and speed-up process learning-cycles. Our CV
i
includes proprietary Characterization Vehicle
®
test chips, including designs of experiments and layout designs, and a proprietary and patented highly parallel electrical functional and parametric-test system, comprised of hardware and software designed to provide an order-of-magnitude reduction in the time required to test our Characterization Vehicle
®
test chips. In addition, our technology embodies many algorithms, which we have developed over the course of many years, and which are implemented in our products including
data
POWER
®
, pdCV
tm
, mæstria
®
, and pdBRIX
tm
, among others. Further, our IP includes methodologies that our implementation teams use as guidelines to drive our customers’ use of our CV
®
test chips and technologies, quantify the yield-loss associated with each process module and design block, simulate the impact of changes to the design and/or to the manufacturing process, and analyze the outcome of executing such changes. We continually enhance our core technologies through the codification of knowledge that we gain in our solution implementations.
4
Our future success and competitive position rely to some extent upon our ability to protect these proprietary technologies and IP, and to prevent competitors from using our systems, methods, and technologies in their products. To accomplish this, we rely primarily on a combination of contractual provisions, confidentiality procedures, trade secrets, and patent, copyright, mask work, and trademark laws. We license our products and technologies pursuant to non-exclusive license agreements that impose restrictions on customers’ use. In addition, we seek to avoid disclosure of our trade secrets, including requiring employees, customers, and others with access to our proprietary information to execute confidentiality agreements with us and restricting access to our source code. We also seek to protect our software, documentation, and other written materials under trade secret and copyright laws. As of December 31, 2010, we held 50 U.S. patents. We intend to prepare additional patent applications when we feel it is beneficial. Characterization Vehicle

Products and Services
Our solutions consist of integration engineering services, proprietary software, and other technologies designed to address our customers’ specific manufacturing and design issues.
Services and Solutions
Manufacturing Process Solutions (“MPS”).
The IC manufacturing process typically involves four sequential phases: research and development to establish unit manufacturing processes, such as units for the metal CMP or lithography processes; integration of these unit processes into functional modules, such as metal or contact modules; a yield ramp of lead products through the entire manufacturing line; and volume manufacturing of all products through the life of the process. We offer solutions targeted to each of these phases designed to accelerate the efficiency of yield learning by shortening the learning cycle, learning more per cycle, and reducing the number of silicon wafers required. Our targeted offerings include:
|
|
•
|
Process R&D:
Our process R&D solutions are designed to help customers increase the robustness of their manufacturing processes by characterizing and reducing the variability of unit processes and device performance with respect to layout characteristics within anticipated process design rules.
|
|
|
•
|
Process Integration and Yield Ramp:
Our process integration and yield ramp solutions are designed to enable our customers to more quickly ramp the yield of new products early in the manufacturing process by characterizing the process-design interactions within each key process module, simulating product yield loss by process module, and prioritizing quantitative yield improvement by design block in real products.
|
Volume Manufacturing Solutions (“VMS”).
Our volume manufacturing solutions are designed to enable our customers to extend our yield ramp services through the life of the process by continuing to collect test data and equipment signals during production and improving yield while reducing the overhead of manufacturing separate test wafers.

Design-for-Manufacturability (“DFM”) Solutions.
Our DFM solutions are designed to enable our customers to optimize yields, improve parametric performance, and reduce product ramp time by integrating manufacturability considerations into the design cycle before a design is sent to the mask shop to more quickly and cost-effectively manufacture IC products. We target these solutions to customers’ requirements by providing the following:
|
|
•
|
Logic DFM Solutions:
Logic DFM solutions include software, IP, CV infrastructure, and services designed to validate customers’ process design kit (PDK) and to maximize functional and parametric yield improvements while achieving requirements for density or performance, for example, in the logic portions of an IC design. A CV® optimized to the design style of an IC design provides any necessary design-specific parametric and functional yield models for the design style. Our software helps designers optimize the yield of the logic portion by using process-specific and design style-specific yield models and technology files that enable identification & implementation of IP design building block improvements that result in enhanced yield.

Software.
Our YRS software analyzes an IC design to compute its systematic and random yield loss. YRS software allows design attribute extraction and feature-based yield modeling. YRS software takes as input a layout that is typically in industry standard format and proprietary yield models generated by running and testing our CV test chips. YRS software is designed to estimate the yield loss due to optical proximity effects, etch micro-loading, dishing in CMP, and other basic process issues.
Circuit Surfer
®
Software.
Our Circuit Surfer software estimates the parametric performance yield and manufacturability of analog/mixed-signal/RF blocks in a design, such as RF transmission, PLLs/DLLs and logic critical paths. Using our Circuit Surfer software, a design engineer is able to estimate how manufacturing process variations will impact circuit performance and yield and then optimizes the circuit to reduce or eliminate the impact of those variations.

YA-FDC™ Tools.
Our YA-FDC software tools allow online modeling to create real-time virtual measurements of final product attributes during processing. These models enable optimization decisions for process control, process adjustments, PM scheduling, tool corrective actions, and wafer dispatching. The real-time decision-making based on the models is designed to reduce product variability and cost simultaneously. YA-FDC tools also enable more rapid diagnosis of yield loss mechanisms identified at the end of wafer processing through application of the developed models.
With the exception of

data
POWER
®
and mæstria
®
are primarily licensed separately, they may also be distributed within our Design-to-Silicon-Yield solutions.
Customers
Our current customers are primarily integrated device manufacturers (“IDMs”), but also include fabless semiconductor design companies and foundries. Our customers’ targeted product segments vary significantly, including microprocessors, memory, graphics, image sensor solutions, and communications. We believe that the adoption of our solutions by such companies for usage in a wide range of products validates the application of our Design-to-Silicon-Yield solutions to the broader semiconductor market.
Global Foundries Inc. (“Global Foundries”), Toshiba Corporation (“Toshiba”), Samsung Electronics (“Samsung”) and International Business Machines Corporation (“IBM”), represented 19%, 18%, 12% and 11%, respectively, of our revenues for the year ended December 31, 2010. IBM, Toshiba, and Global Foundries represented 19%, 17%, and 11%, respectively, of our revenues for the year ended December 31, 2009. Toshiba and IBM represented 18% and 16%, respectively, of our revenues for the year ended December 31, 2008. No other customer accounted for 10% or more of our revenues in 2010, 2009, and 2008.
Sales and Marketing
Our sales strategy is to pursue targeted accounts through a combination of our direct sales force, sales representatives in some local markets, and strategic alliances. For sales in the United States, Europe, Japan, and Korea, we rely primarily on our direct sales team. In Taiwan, we use a combination of our direct sales team and a local sales representative, J.I.T. International Co., Ltd. In Singapore, Malaysia, and Indonesia, we use Kromax South Asia PTE LTD, a local sales representative. We expect to continue to establish strategic alliances with process licensors, vendors in the electronic design automation software, capital equipment for IC production, silicon IP and mask-making software segments to create and take advantage of sales channel and co-marketing opportunities.
After we are engaged by a customer and early in the solution implementation, our engineers seek to establish relationships in the organization and gain an understanding of our customers’ business issues. Our direct sales and solution implementation teams combine their efforts to deepen our customer relationships by expanding our penetration across the customer’s products, processes and technologies. This close working relationship with the customer has the added benefit of helping us identify new product areas and technologies in which we should next focus our research and development efforts.
In the year ended December 31, 2010, we derived 65% of our revenues from customers based in Asia compared to 66% for the year ended December 31, 2009 and 55% for the year ended December 31, 2008. In the year ended December 31, 2010, 21% of our revenues were derived from customers located in the United States as compared to 27% in both of the years ended December 31, 2009 and 2008. We base these calculations on the geographic location of the contracting party. Additional discussion regarding the risks associated with international operations can be found under Item 1A, “Risk Factors”.
See our “Notes to Consolidated Financial Statements”, included under Part II, Item 8. “Financial Statements and Supplementary Data” for additional geographic information.
Research and Development
Our research and development focuses on developing and introducing new proprietary technologies, software products and enhancements to our existing solutions. We use a rapid-prototyping paradigm in the context of the customer engagement to achieve these goals. We have made, and expect to continue to make, substantial investments in research and development. The complexity of our Design-to-Silicon-Yield technologies requires expertise in physical IC design and layout, transistor design and semiconductor physics, semiconductor process integration, numerical algorithms, statistics and software development. We believe that our team of engineers will continue to advance our market and technological leadership. We conduct in-house training for our engineers in the technical areas, as well as focusing on ways to enhance client service skills. At any given time, about one quarter of our research and development engineers are operating in the field, partnered with solution implementation engineers in a deliberate strategy to provide direct feedback between technology development and customer needs. Our research and development expenses were $17.2 million, $19.8 million and $34.0 million in 2010, 2009 and 2008, respectively.

Competition
The semiconductor industry is highly competitive and driven by rapidly changing design and process technologies, evolving standards, short product life cycles, and decreasing prices. While the market for process-design integration technologies and services is in its early stages, it is quickly evolving and we expect market competition to continue to develop and increase. We believe the solution to address the needs of IC companies requires a unified system of yield models, design analysis software, CV test chips, physical IP creation, process control software, and yield management software. Currently, we are the only provider of comprehensive commercial solutions for integrating design and manufacturing processes. We face indirect competition from internal groups at IC companies that use an incomplete set of components not optimized to accelerate process-design integration. Some providers of yield management software, inspection equipment, electronic design automation, or design IP may seek to broaden their product offerings and compete with us.
We face competition for some of the point applications of our solutions including some of those used by the internal groups at IC companies. Specifically there are several suppliers of yield management and/or prediction systems, such as KLA-Tencor, Mentor Graphics (through its acquisition of Ponte Solutions), Rudolph Technologies Inc. (“Rudolph”) (through its acquisition of the Yield Dynamics group), Synopsys, Inc. (“Synopsys”), and process control software, such as Applied Materials, Inc. (through its acquisition of the software division of Brooks Automation, Inc.), BISTel Inc., Rudolph, and Trancom Technology, Inc., and MKS Instruments, Inc. ARM Ltd. and Synopsys (through its acquisition of Virage Logic Corporation) provide standard cells in the physical IP space and Tela provides software for standard cell synthesis, each of which could compete with our pdBRIX™ solution. In addition, Synopsys now appears to offer directly competing DFM solutions, while other EDA suppliers provide alternative DFM solutions that may compete for the same budgetary funds.
We believe the principal factors affecting competition in our market include demonstrated results and reputation, strength of core technology, ability to create innovative technology, and ability to implement solutions for new technology and product generations. We believe that our solutions compete favorably with respect to these factors.
Employees
As of December 31, 2010, we had 292 employees worldwide, including 165 on client service teams, 69 in research and development, 30 in sales and marketing, and 28 in general and administrative functions. Of these employees, 135 are located in the US, 110 in Asia, and 47 in Europe. Worldwide, we had 306 employees as of December 31, 2009 and 375 as of December 31, 2008.
None of our employees are represented by a labor union. Our employees in France and Italy are subject to collective bargaining agreements in those countries. We believe our relationship with our employees is good.

It typically takes us a long time to sell our unique solutions to new customers and into new markets, and that can result in uncertainty and delays in generating revenues.
Our gainshare performance incentives business model is unique and our Design-to-Silicon-Yield solutions are often unfamiliar to new customers. This results in a long sales cycle and requires a significant amount of our senior management’s time and effort. Furthermore, we need to target those individuals within a customer’s organization who have overall responsibility for the profitability of an integrated circuit (“IC”). These individuals tend to be senior management or executive officers. We may face difficulty identifying and establishing contact with such individuals. Even after initial acceptance, due to the complexity of structuring the gainshare performance incentives component, the negotiation and documentation processes can be lengthy. It can take nine months or more to reach a signed contract with a customer. Unexpected delays in our sales cycle could cause our revenues to fall short of expectations. Our efforts to leverage our FDC technology in the relatively new market of the solar panel industry may not be successful. Further, ongoing negotiations and evaluation projects with photovoltaic manufacturers may not result in significant revenues for us if we are unable to close new engagements in these markets on terms favorable to us, in a timely manner, or at all, or if we are unable to successfully deliver our products and services to such markets.
We generate a large percentage of our revenues from a limited number of
customers, so decreased volumes at any one of these customers, or the loss of any one of these customers could significantly reduce our
revenue and results of operations below expectations.
Historically, we have had a small number of large customers for our core Design-to-Silicon-Yield solutions and we expect this to continue in the near term. In the year ended December 31, 2010, four customers accounted for 60% of our revenues, with Global Foundries representing 19%, Toshiba representing 18%, Samsung representing 12% and IBM representing 11%. In the year ended December 31, 2009, three customers accounted for 47% of our revenues, with IBM representing 19%, Toshiba representing 17% and Global Foundries representing 11%. We could lose a customer due to its decision not to engage us on future process nodes, its decision not to develop its own future process node, or as a result of industry consolidation. The loss of any of these customers or a decrease in the manufacturing or sales volumes of their products could significantly reduce our total revenue below expectations. In particular, such a loss could cause significant fluctuations in results of operations because our expenses are fixed in the short term and it takes us a long time to replace customers.

If semiconductor designers and manufacturers do not continue to adopt, or they significantly delay adoption of, our
Design-to-Silicon-Yield solutions, our
revenues will suffer.
If semiconductor designers and manufacturers do not continue to adopt our Design-to-Silicon-Yield solutions, both as currently comprised and as we may offer them in the future, our revenues will decline. We may not be successful if we do not continue to enter into agreements with existing customers and new customers that cover a larger number of IC products and processes. If we do not develop new customer relationships with companies that are integrated device manufacturers (“IDMs”), fabless semiconductor companies, and foundries, as well as system manufacturers, the market acceptance of our solutions will suffer. Factors that may limit adoption of our Design-to-Silicon-Yield solutions by semiconductor companies include:
|
|
•
|
our existing and potential customers’ delay in their adoption of the next process technology;
|
|
|
•
|
IDMs of logic ICs discontinuing or significantly cutting back their investment in the development of new process technology as a result of a shift to a model of outsourcing a larger proportion, or all, of the mass production of their ICs;
|
|
|
•
|
our inability to keep pace with the rapidly evolving technologies and equipment used in the semiconductor design and manufacturing processes;
|
|
|
•
|
our customers’ failure to achieve satisfactory yield improvements using our Design-to-Silicon-Yield solutions;
|
|
|
•
|
fewer processes being developed at our customers and, therefore, a reduction in the potential impact our solutions can add at any single customer; and
|
|
|
•
|
our inability to develop, market, or sell effective solutions that are outside of our traditional logic focus of manufacturing process solutions.
|
Revenues from our gainshare performance incentives is dependent on factors outside of
our control, including the volume of ICs that our customers are able
to sell to their customers.
Our gainshare performance incentives fee component ties the profits of our customers to our own. Through this component, revenues for a particular product are largely determined by the volume of that product that our customer is able to sell to its customers, which is outside of our control. Decreased demand for semiconductor products decreases the volume of products our customers are able to sell, which directly decreases our gainshare performance incentives revenues. Also, our customers may unilaterally decide to implement changes to their manufacturing processes during the period that is covered by gainshare performance incentives, which could negatively affect yield results. Since we currently work on a small number of large projects, any product that does not achieve commercial viability or a significant increase in yield, or sustain significant volume manufacturing during the time we receive gainshare performance incentives, revenues from such customers could significantly reduce our revenue and results of operations below expectations. In addition, if we work with two directly competitive products, volume in one may offset volume, and thus any of our related gainshare performance incentives, in the other product.
The semiconductor market is volatile and unpredictable, which limits our ability to forecast our business and could negatively impact our results of operations
.
The rebound experienced in the semiconductor market in 2010 may not continue, which limits our ability to forecast our business. In 2008 and 2009, the semiconductor industry experienced significant challenges as a result of the severe tightening of the credit markets, turmoil in the financial markets, and weakened global economy. The semiconductor industry historically has been volatile with up cycles and down cycles, due to sudden changes in customers’ manufacturing capacity requirements and spending, which depend in part on capacity utilization, demand for customers’ IC products by consumers, inventory levels relative to demand, and access to affordable capital. As a result of these various factors, the timing and length of any cycles can be difficult to predict. Economic uncertainty exacerbates negative trends in consumer spending and may again cause some of our customers to delay or refrain altogether from entering into new engagements, licensing new or additional software products, or renewing maintenance and support for existing licensed software. This will negatively affect our revenues. Difficulties in obtaining capital and deteriorating market conditions may also lead to the inability of some customers to obtain affordable financing for other purchases, which could tie up funds otherwise budgeted for purchases of our solutions and technologies. Customers with liquidity issues may also lead to additional bad debt expense. Further, uncertainty about future global economic conditions and any affect on the semiconductor industry could make it challenging for us to forecast our operating results, make business decisions, and identify the risks that may affect our business, financial condition and results of operations. If we are not able to timely and appropriately adapt to changes resulting from the difficult macroeconomic environment, our business, financial condition, and results of operations may be significantly negatively affected.
10
Our solution implementations may take longer than budgeted, which could cause us
to lose customers and may result in adjustments to our operating results.
Our solution implementations require a team of engineers to collaborate with our customers to address complex yield loss issues by using our software and other technologies. We must estimate the amount of time needed to complete an existing solution implementation in order to estimate when the engineers will be able to commence a new solution implementation. In addition, our accounting for solution implementation contracts, which generate fixed fees, sometimes require adjustments to profit and loss based on revised estimates during the performance of the contract. These adjustments may have a material effect on our results of operations in the period in which they are made. The estimates giving rise to these risks, which are inherent in fixed-price contracts, include the forecasting of costs and schedules, and contract revenues related to contract performance.
If we are not able to attract, retain, motivate, and strategically locate talented employees, including some key executives, our business may suffer.
Our success and competitiveness depend on our ability to attract, retain, motivate, and strategically locate in our offices around the globe, talented employees, including some of our key executives. Achieving this objective may be difficult due to many factors, including fluctuations in global economic and industry conditions, changes in our management or leadership, the hiring practices at our competitors or customers, cost reduction activities, and the effectiveness of our compensation programs, including equity-based programs. Further, we have had, and expect to continue to have, difficulty in obtaining visas permitting entry for some of our employees that are foreign nationals into the United States, and delays in obtaining visas permitting entry into other key countries, for several of our key personnel, which disrupts our ability to strategically locate our personnel. If we lose the services of any of our key executives or a significant number of our engineers, it could disrupt our ability to implement our business strategy. If we do not successfully attract, retain, and motivate key employees, including key executives, we may be unable to realize our business objectives and our operating results may suffer.
If we do not effectively manage, support, and safeguard our worldwide information systems, and integrate recent and
planned growth, our business strategy may fail.
We have experienced in the past, and may experience in the future, interruptions in our information systems on which our global operations depend. Further, we may face attempts by others to gain unauthorized access through the Internet to our information technology systems, to intentionally hack, interfere with, or cause physical or digital damage to or failure of such systems (such as significant viruses or worms), which attempts we may be unable to prevent. We could be unaware of an incident or its magnitude and effects until after it is too late to prevent it and the damage it may cause. The theft or unauthorized use or publication of our trade secrets and other confidential business information as a result of such an incident could negatively affect our competitive position, the value of our investment in product or research and development, and third parties might assert against us or our customers claims related to resulting losses of confidential or proprietary information or end-user data and/or system reliability. In any such event, our business could be subject to significant disruption, and we could suffer monetary and other losses, including reputational harm.
In addition, we must frequently expand our internal information system to meet increasing demand in storage, computing and communication. Our internal information system is expensive to expand and must be highly secure due to the sensitive nature of our customers’ information that we transmit. Building and managing the support necessary for our growth places significant demands on our management and resources. These demands may divert these resources from the continued growth of our business and implementation of our business strategy. Further, we must adequately train our new personnel, especially our client service and technical support personnel, to effectively and accurately, respond to and support our customers. If we fail to do this, it could lead to dissatisfaction among our customers, which could slow our growth.
Our stock price has been volatile in the past, and our earnings per share and other operating results may be unusually high in a
given quarter, thereby raising investors’ expectations, and then unusually low in the
next quarter, thereby disappointing investors, which could cause our stock price to
drop again and increase potential dilution to our stockholders.
Our stock price has fluctuated widely during the last few years, from a low closing price of $0.97 per share during March 2009 to a high closing price of $9.01 per share during January 2008. A factor in the volatility may be that our historical quarterly operating results have fluctuated. Our future quarterly operating results will likely fluctuate from time to time and may not meet the expectations of securities analysts and investors in some future period, which could cause our stock price to decrease again. A significant reduction in our stock price negatively impacts our ability to raise equity capital in the public markets and increases the cost to us, as measured by dilution to our existing shareholders, of equity financing. In addition, the reduced stock price also increases the cost to us, in terms of dilution, of using our equity for employee compensation or for acquisitions of other businesses. A greatly reduced stock price could also have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest, and fewer business development opportunities. Also, significant volatility in the stock price could be followed by a securities class action lawsuit, which could result in substantial costs and a diversion of our management’s attention and resources.
11
If we fail to protect our intellectual property (“IP”) rights, customers or potential
competitors may be able to use our technologies to develop their own solutions which
could weaken our competitive position, reduce our revenue, or increase our costs.
Our success depends largely on the proprietary nature of our technologies. We currently rely primarily on contractual, patent, copyright, trademark, and trade secret protection. Our pending patent applications may not result in issued patents, and even if issued, they may not be sufficiently broad to protect our proprietary technologies. Litigation may be necessary from time to time to enforce our IP rights or to determine the validity and scope of the proprietary rights of others. As a result of any such litigation, we could lose our proprietary rights and incur substantial unexpected operating costs. Litigation could also divert our resources, including our managerial and engineering resources.
Competition in the market for yield improvement solutions and increased integration
between IC design and manufacturing may intensify in the future, which could impede
our ability to grow or execute our strategy.
Competition in our market may intensify in the future, which could slow our ability to grow or execute our strategy and could lead to increased pricing pressure, negatively impacting our revenues. Our current and potential customers may choose to develop their own solutions internally, particularly if we are slow in deploying our solutions or improving them to meet market needs. These and other competitors may be able to operate with a lower cost structure than our engineering organization, which would give any such competitor’s products a competitive advantage over our solutions. We currently face indirect competition from the internal groups at IC companies and some direct competition from providers of yield management or prediction software such as KLA-Tencor, Mentor Graphics (through its acquisition of Ponte Solutions), Rudolph Technologies, Inc. (“Rudolph”) (through its acquisition of Yield Dynamics), and Synopsys, Inc., and process control software, such as Applied Materials, Inc. (through its acquisition of the software division of Brooks Automation), BISTel Inc., MKS Instruments, Inc., Rudolph and Trancom Technology, Inc. Further, ARM Ltd. and Synopsys (through its acquisition of Virage Logic Corporation) provide standard cells in the physical IP space and Tela provides software for standard cell synthesis, each of which could compete with our pdBRIX™ solution. In addition, electronic design automation suppliers provide alternative DFM solutions that may compete for the same budgetary funds. There may be other providers of commercial solutions for systematic IC yield and performance enhancement of which we are not aware. Further, some providers of yield management software or inspection equipment may seek to broaden their product offerings and compete with us. In addition, we believe that the demand for solutions that address the need for better integration between the silicon design and manufacturing processes may encourage direct competitors to enter into our market. For example, large integrated organizations, such as IDMs, electronic design automation software providers, IC design service companies or semiconductor equipment vendors, may decide to spin-off a business unit that competes with us. Other potential competitors include fabrication facilities that may decide to offer solutions competitive with ours as part of their value proposition to their customers. If these potential competitors change the pricing environment or are able to attract industry partners or customers faster than we can, we may not be able to grow and execute our strategy as quickly or at all.
We face operational and financial risks associated with international operations that
could negatively impact our revenue.
We have in the past expanded our non-U.S. operations and may in the future continue such expansion by establishing overseas subsidiaries, offices, or contractor relationships in locations, if and when, deemed appropriate by our management. Thus, the success of our business is subject to risks inherent in doing business internationally, including in particular:
|
|
•
|
some of our key engineers and other personnel are foreign nationals and they may have difficulty gaining access to the United States and other countries in which our customers or our offices may be located and it may be difficult for us to recruit and retain qualified technical and managerial employees in foreign offices;
|
|
|
•
|
greater difficulty in collecting account receivables resulting in longer collection periods;
|
|
|
•
|
language and other cultural differences may inhibit our sales and marketing efforts and create internal communication problems among our U.S. and foreign research and development teams, increasing the difficulty of managing multiple, remote locations performing various development, quality assurance, and yield ramp analysis projects;
|
|
|
•
|
compliance with, inconsistencies among, and unexpected changes in, a wide variety of foreign laws and regulatory environments with which we are not familiar, including, among other issues, with respect to employees, protection of our IP, and a wide variety of operational regulations and trade and export controls under domestic, foreign, and international law;
|
|
|
•
|
currency risk due to the fact that certain of our payables for our international offices are denominated in the local currency, including the Euro, while virtually all of our revenues is denominated in U.S. dollars;
|
|
|
•
|
quarantine, private travel limitation, or business disruption in regions affecting our operations, stemming from actual, imminent or perceived outbreak of human pandemic or contagious disease;
|
12
|
|
•
|
in the event a larger portion of our revenues becomes denominated in foreign currencies, we would be subject to a potentially significant exchange rate risk; and
|
|
|
•
|
economic or political instability, including but not limited to armed conflict, terrorism, interference with information or communication of networks or systems, and the resulting disruption to economic activity and business operations.
|
Revenues generated from customers in Asia accounted for 65% and 66% of our revenues in the years ended December 31, 2010 and 2009, respectively. Thus, in Asia, in particular, we face the following additional risks:
|
|
•
|
a downturn in Asian economies which could limit our ability to retain existing customers and attract new ones in Asia; and
|
|
|
•
|
if the U.S. dollar increases in value relative to local currencies, including for example, the Japanese Yen, the cost of our solutions will be more expensive to existing and potential local customers and therefore less competitive.
|
We use professionals located in Ramallah, Palestine, who provide various software-related development, quality assurance, maintenance, and other technical support services for certain of our software products. The political uncertainty surrounding the region could disrupt these service providers and thus negatively affect the range of services we are able to provide or our cost for such services.
Measurement of our gainshare performance incentives requires data collection and is
subject to customer agreement, which can result in uncertainty and cause quarterly
results to fluctuate.
We can only recognize revenue based on gainshare performance incentives once we have reached agreement with our customers on their level of yield performance improvements. Because measuring the amount of yield improvement is inherently complicated and dependent on our customers’ internal information systems, there may be uncertainty as to some components of measurement. This could result in our recognition of less revenue than expected. In addition, any delay in measuring revenue attributable to our gainshare performance incentives could cause all of the associated revenue to be delayed until the next quarter. Since we currently have only a few large customers and we are relying on gainshare performance incentives as a significant component of our total revenues, any delay could significantly harm our quarterly results.
Changes in the structure of our customer contracts, including the mix between fixed
and variable revenue and the mix of elements, including perpetual and term-based licenses, can adversely affect the amount and
timing of our total revenues.
Our long-term success is largely dependent upon our ability to structure our future customer contracts to include a larger gainshare performance incentives component relative to the fixed fee component. We typically recognize the fixed fee component earlier than the gainshare performance incentives component so if we are successful in increasing the gainshare performance incentives component of our customer contracts, we will experience an adverse impact on our operating results in the short term as we reduce the fixed fee component. Due to acquisitions and expanded business strategies, the mix of elements in some of our contracts has changed recently and the relative importance of the software component in some of our contracts has increased. We have experienced, and may in the future experience, delays in the expected recognition of revenue associated with generally accepted accounting principles regarding the timing of revenue recognition in multi-element software arrangements, including the effect of acceptance criteria as a result of the change in our contracts. If we fail to meet contractual acceptance criteria on time or at all, the total revenues we receive under a contract could be delayed or decline. Further, if we mix term-based licenses with perpetual licenses, it will impact the timing of the recognition of revenue from that customer. In addition, by increasing the gainshare performance incentives or the software component, we may increase the variability or timing of recognition of our revenue, and therefore increase the risk that our total future revenues will be lower than expected and fluctuate significantly from period to period.
We have a history of losses, we may incur losses in the future and we may be unable
to reach, or thereafter maintain, profitability.
We have experienced losses in the fiscal years ended December 31, 2009, 2008 and in the past. We may not maintain profitability if our costs increase more quickly than we expect or if revenues decrease. In addition, virtually all of our operating expenses are fixed in the short term, so any shortfall in anticipated revenue in a given period could significantly reduce our operating results below expectations. Our accumulated deficit was $130 million as of December 31, 2010. We expect to continue to incur significant expenses in connection with:
|
|
•
|
funding for research and development;
|
|
|
•
|
expansion of our solution implementation teams;
|
|
|
•
|
expansion of our sales and marketing efforts; and
|
13
|
|
•
|
additional non-cash charges relating to amortization and stock-based compensation.
|
As a result, if we do not significantly increase revenues to maintain profitability on a quarterly or annual basis, our stock price could decline. We may be subject to additional impairment of our long-lived assets, which could negatively affect our reported results.
Inadvertent disclosure of our customers’ confidential information could result in
costly litigation and cause us to lose existing and potential customers.
Our customers consider their product yield information and other confidential information, which we must gather in the course of our engagement with the customer, to be extremely competitively sensitive. If we inadvertently disclosed or were required to disclose this information, we would likely lose existing and potential customers and could be subject to costly litigation. In addition, to avoid potential disclosure of confidential information to competitors, some of our customers may, in the future, ask us not to work with key competitive products, which could limit our revenue opportunities.
Our technologies could infringe the IP rights of others, causing
costly litigation and the loss of significant rights.
Significant litigation regarding intellectual property rights exists in the semiconductor industry. It is possible that a third party may claim that our technologies infringe their intellectual property rights or misappropriate their trade secrets. Any claim, even if without merit, could be time consuming to defend, result in costly litigation, or require us to enter into royalty or licensing agreements, which may not be available to us on acceptable terms, or at all. A successful claim of infringement against us in connection with the use of our technologies could adversely affect our business.
Our ability to sell our products may depend on the quality of our support and services offerings, and our failure to offer high-quality support and services could negatively affect our sales and results of operations.
Once our software products are integrated within our customers’ hardware and software systems, our customers may depend on our support organization to resolve any issues relating to our products. A high level of support is critical for the successful marketing and sale of our products. If we do not effectively assist our customers in deploying our products, succeed in helping our customers quickly resolve post-deployment issues, and provide effective ongoing support, our ability to sell our software products to existing customers may be negatively affected, and our reputation with potential customers could be harmed. If our software customers have a poor perception of our support and services offerings, they may choose not to renew software support and maintenance when the current period expires. In addition, due to our international operations, our support organization faces challenges associated with delivering support, training, and documentation where the user’s native language may not be English. If we fail to maintain high-quality support and services, our customers may choose our competitors’ products instead of ours in the future.
Defects in our proprietary technologies, hardware and software tools, and the cost of
support to remedy any such defects could decrease our revenue and our competitive
market share.
If the software, hardware, or proprietary technologies we provide to a customer contain defects that increase our customer’s cost of goods sold and time-to-market or damage our customer’s property, these defects could significantly decrease the market acceptance of our solutions. Further, the cost of support resources required to remedy any defects in our technologies, hardware, or software tools could exceed our expectations. Any actual or perceived defects with our software, hardware, or proprietary technologies may also hinder our ability to attract or retain industry partners or customers, leading to a decrease in our revenue. These defects are frequently found during the period following introduction of new software, hardware, or proprietary technologies or enhancements to existing software, hardware, or proprietary technologies. Our software, hardware, and proprietary technologies may contain errors not discovered until after customer implementation of the silicon design and manufacturing process recommended by us. If our software, hardware, or proprietary technologies contain errors or defects, it could require us to expend significant resources to remedy these problems, which could reduce margins and result in the diversion of technical and other resources from our other development efforts.
Failing to maintain the effectiveness of our internal controls over financial reporting could impede our ability to provide accurate and timely financial information, which could cause our investors to lose confidence in the accuracy and completeness of our financial reports and could cause our stock price to decline.
We have identified material weaknesses in connection with the evaluation of the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act (“Section 404”) as of December 31, 2009 and 2010. These control deficiencies resulted in adjustments during the 2009 audit to our consolidated financial statements for the year ended December 31, 2009, and during the 2010 audit to our consolidated financial statements for the year ended December 31, 2010. See Item 9A of this Annual Report for further discussion of our managements' evaluation of the Company's control environment and our management's plan for remediation. In the future, our management may identify additional deficiencies regarding the design and operating effectiveness of our system of internal control. We may not be able to remediate such deficiencies in time to meet the continuing reporting deadlines imposed by Section 404 and the costs of remediation may be substantial. A material weakness in our internal controls could result in a material misstatement not being prevented or detected, which could result in the need for a restatement of past periods. Moreover, our independent registered public accounting firm may continue to deem that we did not maintain, in all material respects, effective internal control over financial reporting if we are unable to remediate deficiencies on a timely basis. If we fail to remediate the material weaknesses, fail to implement required new or improved controls, encounter difficulties in their implementation, or are unable at any time to assert that we maintain effective internal controls, it could harm our operating results, cause us to fail to meet our SEC reporting obligations on a timely basis, result in material misstatements, and our investors could lose confidence in the accuracy and completeness of our financial reports and our stock price could decline.

Changes in effective tax rates could negatively affect our operating results.
We conduct our business globally and, as a result, are subject to taxation in the United States and foreign countries. Our future tax rates could be affected by numerous factors, including changes in tax laws or the interpretation of such tax laws and changes in accounting policies. Our filings are subject to reviews or audit by the Internal Revenue Service and state, local and foreign taxing authorities. We cannot be sure that any final determination in an audit would not be materially different than the treatment reflected in our historical income tax provisions and accruals. If additional taxes are assessed as a result of an audit, there could be a significant negative effect on our income tax provision and our operating results in the period or periods for which that determination is made.
The uncertainty in the credit markets might impact the value of certain auction-rate
securities we have and we might have to record impairment
charges in the future.
Credit concerns in the capital markets have significantly reduced our ability to liquidate auction-rate securities that we classify as non-current investment securities on our balance sheet. The liquidity of the securities has been reduced by the uncertainty in the credit markets and the exposure of these securities to the financial condition of bond insurance companies. All auction-rate securities we hold have been failing to sell at auction since February 2008 due to an insufficient number of bidders. We reviewed the value of these securities for impairment and concluded that these securities were temporarily impaired. Therefore, during the year ended December 31, 2008, we recorded an unrealized loss of $282,000 as a component of accumulated other comprehensive income (loss). We have concluded that there is no additional impairment as of December 31, 2010 and 2009. In future periods, should the estimated fair value of our auction-rate securities decline further based on market conditions, it could result in additional impairment and could result in the need to classify such impairment as other-than-temporary, which will result in a charge to operations.
None.
Our principal executive offices are located in San Jose, California where we lease approximately 39,300 square feet under a lease that expires in September 2013. In addition, we lease laboratory space in San Jose, California under a lease that expires in November 2014. We lease other office space in Pennsylvania and Texas in the United States. In addition, we have offices in France, Germany, Italy, China, Japan, Korea, Singapore, and Taiwan with an aggregate of approximately 34,600 square feet each under various leases that expire at different times through 2013. We believe our existing facilities and those in negotiation are adequate to meet our current needs and are being utilized consistently with our past practice.
From time to time, we are subject to various claims and legal proceedings that arise in the ordinary course of business. Although we currently believe that the ultimate outcome of any of these claims and proceedings, individually and in the aggregate, will not have a material adverse effect on our financial position or overall trends in results of operations, litigation is subject to inherent uncertainty. If an unfavorable ruling occurs in any of the legal proceedings described below, our financial position and results of operations and cash flows could be negatively affected. We accrue for losses related to litigation when a potential loss is probable and the loss can be reasonably estimated in accordance with FASB requirements. With respect to each of the matters below, we have determined a potential loss is not probable at this time and, accordingly, no amount has been accrued at December 31, 2010. As we continue to monitor these matters, however, our determination could change and we may decide a different reserve is appropriate in the future.
Philip Steven Melman filed a complaint against us and our Chief Executive Officer on December 7, 2009 in the Superior Court for Santa Clara County. In the complaint, Mr. Melman alleges wrongful discharge based on discrimination, fraud, breach of contract and similar theories, in connection with the termination of Mr. Melman's employment with us. The complaint seeks compensatory and punitive damages, any other available remedies, as well as attorney's fees and costs. We believe the complaint is without merit and intend to vigorously oppose it.
Global Software Services, Inc., a Palestinian corporation (“GSSI”), filed a complaint against us on February 16, 2010 in the Superior Court for Santa Clara County. In the complaint, GSSI alleged that we failed to pay GSSI amounts owed under a Professional Services Agreement pursuant to which GSSI was providing software-related development and support services to us. In addition, GSSI alleged that we interfered with GSSI’s business relationships and employee relationships and that we engaged in unfair business practices in violation of Business & Professions Code Section 17200. The complaint sought compensatory and punitive damages, disgorgement and restitution, injunctive relief and any other available equitable remedies, as well as attorney's fees and costs. On December 2, 2010, the court dismissed GSSI's action with prejudice.

Overview
We analyze our customers’ IC design and manufacturing processes to identify, quantify, and correct the issues that cause yield loss to improve our customers’ profitability by improving time-to-market, increasing yield and reducing total design and manufacturing costs. We package our solutions in various ways to meet our customers’ specific business and budgetary needs, each of which provides us various revenue streams. We receive a mix of fixed fees and variable, performance-based fees for the vast majority of our yield improvement solutions. The fixed fees are typically reflective of the length of time and the resources needed to characterize a customer’s manufacturing process and receive preliminary results of proposed yield improvement suggestions. The variable fee, or what we call gainshare, usually depends on our achieving certain yield targets by a deadline. Variable fees are currently typically tied to wafer volume on the node size of the manufacturing facility where we performed the yield improvement solutions. We receive license fees and service fees for related installation, integration, training, and maintenance and support services for our software that we license on a stand-alone basis.
History
From our incorporation in 1992 through late 1995, we were primarily focused on research and development of our proprietary manufacturing process simulation and yield and performance modeling software. From late 1995 through late 1998, we continued to refine and sell our software, while expanding our offering to include yield and performance improvement consulting services. In late 1998, we began to sell our software and consulting services, together with our newly developed proprietary technologies, under the term Design-to-Silicon-Yield solutions, reflecting our current business model. In April 2000, we expanded our research and development team and gained additional technology by acquiring AISS. AISS now operates as PDF Solutions, GmbH, a German company, which continues to develop software and provide development services to the semiconductor industry. In July 2001, we completed the initial public offering of our common stock. In 2003, we enhanced our product and service offerings, including increased software applications, through the acquisitions of IDS and WaferYield. In 2006, we further complemented our technology offering by acquiring SiA and adding its FDC software capabilities to our integrated solution. In 2007, we increased our IP solutions portfolio, particularly in logic design technology, through the acquisition of Fabbrix. In 2008, we solidified our market leading position in the FDC software market, particularly in Korea, and now provide complementary technology to our mæstria® product through the acquisition of certain assets of Triant.
Industry Trend
Despite the general economic turmoil beginning in 2008 and continuing through 2009, the semiconductor market rebounded in 2010. We believe that logic foundries were running at or near capacity at times during the year, and a supply constraint at advanced nodes developed. With high utilization rates, foundries appeared to increase spending during the year. This trend resulted in an increase in our business and improved results of operations in 2010. Growth may, however, lessen in 2011.
Generally, the demand for consumer electronics and communications devices continues to drive technological innovation in the semiconductor industry as the need for products with greater performance, lower power consumption, reduced costs and smaller size continues to grow with each new product generation. In addition, advances in computing systems and mobile devices have fueled demand for higher capacity memory chips. To meet these demands, IC manufacturers and designers are constantly challenged to improve the overall performance of their ICs by designing and manufacturing ICs with more embedded applications to create greater functionality while lowering cost per transistor. As a result, both logic and memory manufacturers have migrated to more and more advanced manufacturing nodes, capable of integrating more devices with higher performance, higher density, and lower power. As this trend continues, companies will continually be challenged to improve process capabilities to optimally produce ICs with minimal random and systematic yield loss, which is driven by the lack of compatibility between the design and its respective manufacturing process. We believe that as volume production of deep submicron ICs continues to grow, the difficulties of integrating IC designs with their respective processes and ramping new manufacturing processes will create a greater need for products and services that address the yield loss and escalating cost issues the semiconductor industry is facing today and will face in the future.
Financial Highlights
The following were our financial highlights for the year ended December 31, 2010:
|
|
•
|
Total revenues were $61.7 million, which was an increase of $13.2 million, or 27%, compared to the year ended December 31, 2009. Design-to-Silicon-Yield solutions revenues were $43.1 million, which was an increase of $10.4 million, or 32%, from the year ended December 31, 2009. The increase in Design-to-Silicon-Yield solutions revenues was primarily the result of higher bookings, as customers have begun to increase investment in leading-edge technology. Gainshare performance incentives revenues were $18.6 million, which was an increase of $2.8 million, or 18%, from the year ended December 31, 2009. The increase in revenues from gainshare performance incentives was primarily the result of increased volumes in customer manufacturing facilities.

|
|
•
|
Net income for the year ended December 31, 2010 was $0.2 million, compared to a net loss of $(17.5) million for the year ended December 31, 2009. The move to net income from net loss was primarily attributable to a significant increase in revenues, decreased restructuring expenses and a decrease in salary and facilities expense as the result of decreased headcount due to restructuring activities in the prior year.
|
|
|
•
|
Net income per basic and diluted share was $0.01 for the year ended December 31, 2010 compared to a net loss per basic and diluted share of $(0.66) for the year ended December 31, 2009.
|
|
|
•
|
Cash, cash equivalents and investments increased $3.3 million from $35.6 million at December 31, 2009 to $38.9 million at December 31, 2010, primarily due to cash from operating activities during the period.

Critical Accounting Policies
The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires us to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Note 1 of Notes to Consolidated Financial Statements describes the significant accounting policies and methods used in the preparation of the Consolidated Financial Statements. We consider the accounting policies described below to be our critical accounting policies. These critical accounting policies are impacted significantly by judgments, assumptions, and estimates used in the preparation of the Consolidated Financial Statements and actual results could differ materially from the amounts reported based on these policies.
Revenue Recognition
We derive revenues from two sources: Design-to-Silicon-Yield Solutions, which include Services and Software Licenses, and Gainshare Performance Incentives.
Design-to-Silicon-Yield Solutions
— Revenues that are derived from Design-to-Silicon-Yield solutions comes from services and software licenses. We recognize revenue for each element of Design-to-Silicon-Yield solutions as follows:
Services
— We generate a significant portion of our Design-to-Silicon-Yield solutions revenues from fixed-price solution implementation service contracts delivered over a specific period of time. These contracts require reliable estimation of costs to perform obligations and the overall scope of each engagement. Revenues under contracts for solution implementation services are recognized as services are performed using the cost-to-cost percentage of completion method of contract accounting. Losses on solution implementation contracts are recognized in the period when they become evident. Revisions in profit estimates are reflected in the period in which the conditions that require the revisions become known and can be estimated. If we do not accurately estimate the resources required or the scope of work to be performed, or do not manage the projects properly within the planned period of time or satisfy our obligations under contracts, resulting contract margins could be materially different than those anticipated when the contracts were executed. Any such reductions in contract margin could have a material negative impact on our operating results.
On occasion, we license our software products as a component of our fixed price service contracts. In such instances, the software products are licensed to customers over a specified term of the agreement with support and maintenance to be provided over the license term.
In October 2009, the Financial Accounting Standards Board (“FASB”) amended the accounting standards for multiple-deliverable revenue arrangements to:
|
•
|
provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated, and how the consideration should be allocated;
|
|
•
|
require an entity to allocate revenue in an arrangement using best estimated selling prices (“BESP”) of deliverables if a vendor does not have vendor-specific objective evidence of selling price (“VSOE”) or third-party evidence of selling price (“TPE”); and
|
21
|
•
|
eliminate the use of the residual method and require an entity to allocate revenue using the relative selling price method.
|
We elected to early adopt this accounting standard on April 1, 2010 on a prospective basis for applicable transactions originating or materially modified after January 1, 2010.
This guidance does not generally change the accounting for the Company’s software transactions. It only affects certain revenue arrangements that include both solution implementation services and software products that are not essential to the provision of these services. The amount of product and service revenue recognized in a given period is affected by our judgment as to whether an arrangement includes multiple deliverables and, if so, our determination of the fair value of each deliverable. In general, VSOE does not exist for our solution implementation services and software products. Because our services and products include our unique technology, we are not able to determine TPE. Therefore, we will use BESP in our allocation of arrangement consideration. In determining BESP, we apply significant judgment as we weigh a variety of factors, based on the facts and circumstances of the arrangement. We typically arrive at an BESP for a product or service that is not sold separately by considering company-specific factors such as geographies, internal costs, gross margin objectives, pricing practices used to establish bundled pricing, and existing portfolio pricing and discounting.
After fair value is established for each deliverable, the total transaction amount is allocated to each deliverable based upon its relative fair value. Fees allocated to solution implementation services are recognized using the cost-to-cost percentage of completion method of contract accounting. Fees allocated to software and related support and maintenance are recognized under software revenue recognition guidance.
Prior to the adoption of this new accounting standard, under these arrangements, where VSOE existed for the support and maintenance element, the support and maintenance revenue was recognized separately over the term of the supporting period and the remaining fee was recognized as services are performed using the cost-to-cost percentage of completion method of contract accounting.
The impact on total revenues from the adoption of this new accounting standard is shown in the following table (in thousands). Due to the nature of the arrangements, the Company is currently unable to determine the impact of the adoption of this new accounting standard on future revenues.

Software Licenses
— We also license our software products separately from our solution implementation services. For software license arrangements that do not require significant modification or customization of the underlying software, software license revenue is recognized under the residual method when (1) persuasive evidence of an arrangement exists, (2) delivery has occurred, (3) the fee is fixed or determinable, (4) collectability is probable, and (5) the arrangement does not require services that are essential to the functionality of the software. When arrangements include multiple elements such as support and maintenance, consulting (other than for our fixed price solution implementations), installation, and training, revenue is allocated to each element of a transaction based upon its fair value as determined by our VSOE and such services are recorded as services revenues. VSOE for maintenance is generally established based upon negotiated renewal rates while VSOE for consulting, installation, and training services is established based upon our customary pricing for such services when sold separately. Revenues for software licenses with extended payment terms are not recognized in excess of amounts due. For software license arrangements that require significant modification or customization of the underlying software, the software license revenues are recognized as services are performed using the cost-to-cost percentage of completion method of contract accounting, and such revenues are recorded as services revenue.
22
Gainshare Performance Incentives
— When we enter into a contract to provide yield improvement services, the contract usually includes two components: (1) a fixed fee for performance by us of services delivered over a specific period of time; and (2) a gainshare performance incentives component where the customer may pay a variable fee, usually after the fixed fee period has ended. Revenues derived from gainshare performance incentives represent profit sharing and performance incentives earned based upon our customers reaching certain defined operational levels established in related solution implementation service contracts. Gainshare performance incentives periods are usually subsequent to the delivery of all contractual services and therefore have no cost to us. Due to the uncertainties surrounding attainment of such operational levels, we recognize gainshare performance incentives revenues (to the extent of completion of the related solution implementation services) upon receipt of performance reports or other related information from our customers supporting the determination of amounts and probability of collection. Gainshare performance incentives revenues are dependent on many factors which are outside our control, including among others, continued production of the related ICs by our customers, sustained yield improvements by our customers, and our ability to enter into new Design-to-Silicon-Yield solutions contracts containing provisions for gainshare performance incentives.
Intangible Assets
As of December 31, 2010 and December 31, 2009, the recorded value of our intangible assets was $1.4 million and $3.0 million, respectively. Impairment on acquired intangible assets is evaluated when indicators of impairment exist. In assessing the valuation and recoverability of our long-lived assets, we must make assumptions regarding estimated future cash flows to be derived from the acquired assets. The assumptions used in the fair value calculations change from year to year and include revenue growth rates, operating margins, risk adjusted discount rates and future economic and market conditions. Changes in these estimates based on changed economic conditions or business strategies could result in material impairment charges in future periods. We base our fair value estimates on assumptions we believe to be reasonable. Actual future results may differ from those estimates. If these estimates or their related assumptions change in the future, we may be required to record impairment charges for these assets, which would have a material adverse effect on our operating results. During the year ended December 31, 2010, there were no indicators of impairment related to our intangible assets.
We are currently amortizing our acquired intangible assets over estimated useful lives of one to seven years, which are based on the estimated period of benefit to be derived from such assets. However, a decrease in the estimated useful lives of such assets would cause additional amortization expense or an impairment of such assets in future periods.
Income Taxes
We must assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, we must establish a valuation allowance. Changes in the net deferred tax assets, less offsetting valuation allowance, in a period are recorded through the income tax provision in the consolidated statements of operations. For the year ended December 31, 2008, we concluded that a valuation allowance was required based on our evaluation and weighting of the positive and negative evidence. We continued to carry a valuation allowance against our U.S. and certain foreign deferred tax assets as of December 31, 2010 and 2009. See Note 9 to the consolidated financial statements for further discussion. If, in the future, we determine that these deferred tax assets are more likely than not to be realized, a release of all or part, of the related valuation allowance could result in a material income tax benefit in the period such determination is made.
Our income tax calculations are based on application of the respective U.S. federal, state or foreign tax law. Our tax filings, however, are subject to audit by the respective tax authorities. Accordingly, we recognize tax liabilities based upon our estimate of whether, and the extent to which, additional taxes will be due when such estimates are more-likely-than-not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. To the extent the final tax liabilities are different than the amounts originally accrued, the increases or decreases are recorded as income tax expense or benefit in the consolidated statements of operations.
Stock-Based Compensation
Stock-based compensation is estimated at the grant date based on the award’s fair value and is recognized on a straight-line basis over the vesting periods of the applicable stock purchase rights and stock options, generally four years. As stock-based compensation expense recognized is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
We have elected to use the Black-Scholes-Merton option-pricing model, which incorporates various assumptions including volatility, expected life and interest rates. The expected volatility is based on the historical volatility of our common stock over the most recent period commensurate with the estimated expected life of stock options. The expected life of an award is based on historical experience and on the terms and conditions of the stock awards granted to employees. The interest rate assumption is based upon observed Treasury yield curve rates appropriate for the expected life of stock options.

Design-to-Silicon-Yield Solutions.
Design-to-Silicon-Yield solutions revenues are derived from services (including solution implementations, software support and maintenance, consulting, and training) and software licenses, provided during our customer yield improvement engagements and solution product sales.
Design-to-Silicon-Yield solutions revenues increased $10.4 million for the year ended December 31, 2010 compared to the year ended December 31, 2009, primarily due to an increase of $9.5 million in fixed fee integrated solutions and an increase of $0.6 million in software and software related services. The increases were primarily the result of higher bookings, as customers have begun to invest in leading edge technology as the semiconductor industry has begun to rebound. We booked eight new fixed-price solution implementation service contracts and five extensions to existing service contracts during the year ended December 31, 2010, as compared to five new service contacts and two extensions to existing service contracts during the year ended December 31, 2009. The rebound in the semiconductor industry has been the primary contributor to this increase. Our Design-to-Silicon-Yield revenues may fluctuate in the future and are dependent on a number of factors, including the semiconductor industry’s acceptance of our products, the timing of purchases by existing customers, and our ability to attract new customers and penetrate new markets including photovoltaic and LED, and further penetration of our current customer base.
Gainshare Performance Incentives.
Gainshare performance incentives revenues represent profit sharing and performance incentives earned based upon our customers reaching certain defined operational levels. Revenues derived from gainshare performance incentives increased $2.8 million for the year ended December 31, 2010 compared to the year ended December 31, 2009, primarily due to increases in wafer volumes at our customers’ sites. Revenues from gainshare performance incentives were generated from seven customers and eight engagements for the year ended December 31, 2010 and seven customers and nine engagements for the year ended December 31, 2009.

Costs of Design-to-Silicon-Yield Solutions.
Costs of Design-to-Silicon-Yield solutions consist of costs incurred to provide and support our services, costs recognized in connection with licensing our software, and amortization and impairment of acquired technology.
Direct Costs of Design-to-Silicon-Yield Solutions.
Direct costs of Design-to-Silicon-Yield solutions consist of services costs and software licenses costs. Services costs consist of material, labor, overhead costs, and stock-based compensation charges associated with solution implementations. Costs include purchased materials, employee compensation and related benefits, travel and facilities-related costs. Software license costs consist of costs associated with licensing third-party software sold in conjunction with our software products and expenses incurred to produce and distribute our product documentation. Direct costs of Design-to-Silicon-Yield Solutions increased $1.6 million for the year ended December 31, 2010 compared to the year ended December 31, 2009. The increase was primarily due to an increase of $555,000 in travel expense related to increased project activity, $528,000 in equipment expense related to deployments to new engagements in 2010 and an increase of $436,000 in stock-based compensation charges. The direct costs of Design-to-Silicon-Yield solutions decreased as a percentage of revenues in 2010 to 39%, compared to 47% in 2009. Because certain costs are relatively fixed in nature, even though total costs had increased due to increased engagement activity, the increase in revenues had a greater effect on our gross margin.
Amortization and Impairment of Acquired Technology.
Amortization of acquired technology consists of amortization of intangibles acquired as a result of certain business combinations. Amortization of acquired technology decreased $153,000 for the year ended December 31, 2010 compared to the year ended December 31, 2009, primarily due to certain intangible assets becoming fully amortized. Assuming we acquire no other intangible assets, we anticipate amortization of acquired technology to be $626,000 in 2011 and $261,000 in 2012.

Research and Development.
Research and development expenses consist primarily of personnel-related costs to support product development activities, including compensation and benefits, outside development services, travel, facilities cost allocations, and stock-based compensation charges. Research and development expenses decreased $2.6 million for the year ended December 31, 2010 compared to the year ended December 31, 2009, primarily due to a decrease of $2.1 million in personnel and facilities expenses and a $724,000 decrease in subcontractor expense primarily as the result of our cost control efforts. We anticipate our expenses in research and development will fluctuate in absolute dollars from period to period as a result of cost control initiatives and the timing of when we hire new personnel based on the scope and timing of product development projects.

Selling, general and administrative expenses consist primarily of compensation and benefits for sales, marketing and general and administrative personnel in addition to outside sales commissions, legal and accounting services, marketing communications, travel and facilities cost allocations, and stock-based compensation charges. Selling, general and administrative expenses decreased $572,000 for the year ended December 31, 2010 compared to the year ended December 31, 2009 primarily due to a decrease of $1.7 million in personnel, commissions and facilities expenses as a result of our cost control efforts, partially offset by an increase of $708,000 in legal fees related to ongoing litigation and an increase of $374,000 in accounting fees. We anticipate our selling, general and administrative expenses will fluctuate in absolute dollars from period to period as a result of changes in litigation, cost control initiatives and the need to support sales efforts in the future.

Design-to-Silicon-Yield Solutions.
Design-to-Silicon-Yield solutions revenues decreased $22.5 million for the year ended December 31, 2009 compared to the year ended December 31, 2008, primarily due to a decrease of $13.8 million in fixed fee integrated solutions and a decrease of $8.3 million in software and software related services. The decreases were primarily the result of lower bookings, as customers have delayed purchases for capacity expansion and investment in leading edge technology in anticipation of a significant downturn in the semiconductor industry. We booked five new fixed-price solution implementation service contracts and two extensions to existing service contracts during the year ended December 31, 2009, as compared to seven new service contacts and four extensions to existing service contracts during the year ended December 31, 2008. The dramatic downturn in the semiconductor industry combined with weakness in worldwide economies were the primary contributors to this shortfall.

Impairment on Goodwill and Other Acquired Intangible Assets.
During the three months ended December 31, 2008, we recognized an impairment of $64.0 million on our goodwill and $2.8 million on our other acquired intangible assets (excluding the impairment of acquired technology), as a result of management’s review for potential impairment on the carrying value of such assets due to the deterioration of our operating results and the dramatic downturn in the semiconductor industry combined with weakness in worldwide economies. There was no impairment charge recorded during the year ended December 31, 2009.

Interest and Other Income, Net.
Interest and other income, net, decreased $116,000 for the year ended December 31, 2009 compared to the year ended December 31, 2008, primarily due to decreases in interest income of $834,000 from lower average cash, cash equivalent and investments balances and lower interest rates during the year, partially offset by a loss of $445,000 on the sale of commercial paper from a bankrupt financial institution during the three months ended September 30, 2008, and a gain of $393,000 on debt extinguishment during the three months ended September 30, 2009 associated with the forgiveness of a loan we assumed at the time of acquisition of Si Automation S.A.

Income Tax Provision.
Income tax provision decreased $7.3 million for the year ended December 31, 2009 compared to the year ended December 31, 2008, primarily due to the establishment of a valuation allowance for deferred tax assets for the year ended December 31, 2008. During 2008, a valuation allowance was established for substantially all net deferred tax assets after management concluded that it was more likely than not that, based on the objective evidence available, our net deferred tax assets would not be fully realizable.
Liquidity and Capital Resources
Operating Activities
Cash flows from operating activities consist of net income adjusted for certain non-cash items and changes in assets and liabilities. Net cash provided by operating activities was $2.7 million for the year ended December 31, 2010, a change of $7.3 million compared to cash used in operating activities of $(4.6) million for the year ended December 31, 2009, primarily due to the generation of net income and the reduction in deferred revenue, partially offset by changes in accounts receivable and various accruals.
28
Accounts receivable increased $3.6 million as of December 31, 2010 compared to December 31, 2009, primarily due to increased billings on higher revenues. Accounts receivable decreased $5.2 million as of December 31, 2009 compared to December 31, 2008 primarily due to a decline in revenue. Accrued compensation and related benefits decreased $0.4 million as of December 31, 2010 compared to December 31, 2009 primarily due to paid vacation used in company-wide shutdowns, the result of our cost control efforts. Accrued compensation and related benefits decreased $2.1 million as of December 31, 2009 compared to December 31, 2008 primarily due to paid vacation used in company-wide shutdowns, the result of our cost control efforts. Accrued and other liabilities decreased $1.4 million as of December 31, 2010 compared to December 31, 2009, primarily due to decreases in accrued restructuring, accrued outside sales commissions and accrued legal expenses. Accrued and other liabilities increased $240,000 as of December 31, 2009 compared to December 31, 2008 primarily due to an adjustment to the tax liability for uncertain tax positions partially offset by the amortization of deferred rent. Accounts payable increased $20,000 as of December 31, 2010 compared to December 31, 2009 primarily due to the timing of vendor payments. Accounts payable decreased $392,000 as of December 31, 2009 compared to December 31, 2008 primarily due to the timing of vendor payments.
Investing Activities
Cash flows from investing activities consist of proceeds from investment maturities and sales, offset by payments for investments acquired, payments for businesses acquired, and payments for capital expenditures. Net cash used in investing activities was $(121,000) for the year ended December 31, 2010, a change of $8.6 million compared to net cash provided by investing activities of $8.5 million for the year ended December 31, 2009, primarily due to no sales of available-for-sale securities during the year ended December 31, 2010, partially offset by lower purchases of property and equipment. Net cash provided by investing activities was $8.5 million for the year ended December 31, 2009, a change $11.4 million compared to net cash used in investing activities of $(2.9) million for the year ended December 31, 2009, primarily due to no purchases of investments during the year ended December 31, 2009, partially offset by lower proceeds from maturities and sales of available-for-sale securities. We purchased $27.1 million of available-for-sale securities in the year ended December 31, 2008 while we had no such purchases during the year ended December 31, 2009. We also spent $1.6 million in cash to acquire certain assets from Triant during the year ended December 31, 2008. Proceeds from maturities and sales of available-for sale securities were $9.1 million during the year ended December 31, 2009 compared to $26.9 million during the year ended December 31, 2008.
Financing Activities
Cash flows from financing activities consist of proceeds from sales of shares through employee equity incentive plans, payments for purchase of treasury stock, and principal payments on long-term obligations. Net cash provided by financing activities was $726,000 for the year ended December 31, 2010, an increase of $423,000 compared to $303,000 provided by financing activities for the year ended December 31, 2009, primarily due to higher proceeds from sales of shares through our employee equity incentive plans and lower principal payments on long-term obligations. Net cash provided by financing activities was $303,000 for the year ended December 31, 2009, a change of $6.9 million compared to $(6.6) million used in financing activities for the year ended December 31, 2008, primarily due to repurchases of 2.2 million shares of our common stock for $6.9 million on the open market during the year ended December 31, 2008.
Liquidity
As of December 31, 2010, our working capital was $52.5 million, compared to $45.2 million as of December 31, 2009. Cash, cash equivalents, and short-term investments as of December 31, 2010 were $38.2 million, an increase of $3.3 million compared to $34.9 million as of December 31, 2009, primarily attributable to net cash provided by operating activities. We anticipate that our overall expenses, as well as planned capital expenditures, may constitute a material use of our cash resources. In addition, we may use cash resources to repurchase common stock or fund potential investments in, or acquisitions of, complementary products, technologies or businesses. We believe that our existing cash resources and anticipated funds from operations will satisfy our cash requirements to fund our operating activities, capital expenditures and other obligations for at least the next twelve months. However, in the event that during such period, or thereafter, we are not successful in generating sufficient cash flows from our operations we may need to raise additional capital through private or public financings, strategic relationships or other arrangements, which may not be available to us on acceptable terms or at all, particularly in current capital market environment.
As of December 31, 2010, our non-current investments included auction-rate securities with a fair value of $718,000. The auction-rate securities are measured at fair value using significant unobservable inputs (Level 3 inputs) and accounted for approximately 3% of total assets that are measured at fair value on a recurring basis. See Note 12 to “Notes to Consolidated Financial Statements” in Part IV, and Item 7A. “Quantitative and Qualitative Disclosures About Market Risk” in Part II and Note 2 to “Notes to Consolidated Financial Statements” in Part IV in this Annual Report on Form 10-K for further discussion.
Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements, investments in special purpose entities or undisclosed borrowings or debt, other than operating leases on our facilities. As of December 31, 2010, other than Euro denominated payables, we had no foreign currency contracts outstanding.
We indemnify certain customers from third-party claims of intellectual property infringement relating to the use of our products. Historically, costs related to these guarantees of indemnification have not been significant. We are unable to estimate the maximum potential impact of these guarantees on our future results of operations.

The following discusses our exposure to market risk related to changes in interest rates and foreign currency exchange rates. We do not currently own any equity investments, nor do we expect to own any in the foreseeable future. This discussion contains forward-looking statements that are subject to risks and uncertainties. Actual results could vary materially as a result of a number of factors.
Interest Rate Risk.
As of December 31, 2010, we had cash and cash equivalents of $38.2 million. Cash and cash equivalents consisted of cash and highly liquid money market instruments. We would not expect our operating results or cash flows to be affected to any significant degree by the effect of a sudden change in market interest on our portfolio. A hypothetical increase in market interest rates of 100 basis points from the market rates in effect at December 31, 2010 would cause the fair value of these investments to decrease by an immaterial amount which would not have significantly impacted our financial position or results of operations. Declines in interest rates over time will result in lower interest income and interest expense.
As of December 31, 2010, we held auction-rate securities with a par value of $1.0 million. Auction-rate securities are variable rate debt instruments whose interest rates are reset through a “Dutch” auction process at regular intervals, typically every 28 days. A portion of these securities are insured by third party bond insurers and are collateralized by student loans guaranteed by governmental agencies and private entities. The liquidity of the securities has been negatively impacted by the uncertainty in the credit markets and the exposure of these securities to the financial condition of bond insurance companies. All auction-rate securities we hold have been failing to sell at auction since February 2008 due to an insufficient number of bidders. Therefore we reviewed the value of these securities for impairment. The cumulative impairment for these securities as of December 31, 2010 was $282,000, which is included in other comprehensive income (loss). In future periods, the estimated fair value of our auction-rate securities could decline further based on market conditions, which could result in additional impairment.
Foreign Currency and Exchange Risk.
Certain of our payables for our international offices are denominated in the local currency, including the Euro. Therefore, a portion of our operating expenditures is subject to foreign currency risks. The effect of an immediate 10% adverse change in exchange rates on foreign denominated payables as of December 31, 2010 would result in a loss of an immaterial amount. As of December 31, 2010, we did not have outstanding hedging contracts, although we may enter into such contracts in the future. We intend to monitor our foreign currency exposure. Future exchange rate fluctuations may have a material negative impact on our business.
The consolidated financial statements and supplementary data required by this Item 8 are listed in Item 15(a)(1) of this Form 10-K.

None.
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our "disclosure controls and procedures" as defined in Exchange Act Rules 13a-15(e) and 15d-15(e) as of December 31, 2010 in connection with the filing of this Annual Report on Form 10-K. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2010, in light of the material weaknesses described below, our disclosure controls and procedures were not effective to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in rules and forms of the SEC and accumulated and communicated to our management as appropriate to allow timely decisions regarding required disclosure.
Management's Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, for the Company. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2010. This evaluation was based on the framework established in
Internal Control—Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO").
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis. Based on our assessment, management concluded that the Company did not maintain effective internal control over financial reporting as of December 31, 2010 based on the criteria set forth in
Internal Control—Integrated Framework
issued by COSO because management identified the following material weaknesses that existed as of that date:
Lack of Resources or Expertise to Provide Reasonable Assurance for the Accurate Application of GAAP in Non-routine or Complex Transactions
. We did not maintain appropriate expertise or resources in order to provide reasonable assurance for the accuracy of accounting in accordance with generally accepted accounting principles as to complex or non-routine areas, which also contributed to the additional material weaknesses that follow.
Controls to Provide Reasonable Assurance for the Accuracy of Accounting for Revenue Transactions.
We did not maintain effective controls to provide reasonable assurance for the accuracy of accounting in accordance with generally accepted accounting principles as to percentage of completion contracts, including deferred costs and cost estimates, and certain of our multi-element revenue arrangements.
Controls to Provide Reasonable Assurance for the Accuracy of Stock-based Compensation Transactions.
We did not maintain effective controls to provide reasonable assurance for the accuracy of accounting in accordance with generally accepted accounting principles as to stock-based compensation awards, including terminations and non-routine modifications.
The control deficiencies described above resulted in audit adjustments to the Company's consolidated financial statements for the year ended December 31, 2010 with respect to the following accounts: revenue, accounts receivable, billings in excess of recognized revenues, deferred cost, stock-based compensation expense, additional-paid-in-capital, and accrued and other current liabilities. Additionally, these control deficiencies could result in further misstatements to the aforementioned accounts that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected. Accordingly, management has determined that these control deficiencies constitute material weaknesses as of December 31, 2010.
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.
The effectiveness of the Company's internal control over financial reporting as of December 31, 2010 has been audited by PricewaterhouseCoopers LLP, the Company's independent registered public accounting firm, as stated in their report which appears in this Annual Report on Form 10-K.
Changes in Internal Control over Financial Reporting
There were changes in our internal control over financial reporting that occurred during the fiscal quarter ended December 31, 2010 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting, specifically related to the departure of the Company's Revenue & Reporting Manager and Director of Finance during the quarter.
Management's Plan for Remediation
Management is developing a remediation plan to address the control deficiencies described above. The remediation efforts are expected to include the following:
|
·
|
Hire personnel with requisite experience for non-routine or complex transactions, including with respect to the application of generally accepted accounting principles for percentage of completion contracts, certain multi-element revenue arrangements, and stock-based compensation transactions;
|
|
·
|
Expand controls to include identification of non-routine and complex transactions for increased periodic and on-going review by high-level personnel with the requisite expertise;
|
|
·
|
Implement procedures to ensure that our revenue controls are enhanced to include specific consideration of the accounting for contract costs and the cost estimation process for the Company's design-to-silicon yield services contracts; and,
|
|
·
|
On-going training of our employees on generally accepted accounting principles in general, and existing and new policies and procedures around revenue and stock-based compensation in particular.
|
Management is developing a detailed plan and timetable for the implementation of the foregoing remediation efforts and will monitor the implementation. In addition, under the direction of the Audit and Corporate Governance Committee, management will continue to review and make necessary changes to the overall design of the Company’s internal control environment, as well as to policies and procedures to improve the overall effectiveness of internal control over financial reporting.
Management currently believes the foregoing efforts will effectively remediate these material weaknesses. As we continue to evaluate and work to improve our internal control over financial reporting, our management may determine to take additional measures or to modify the measures described above.
None.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of PDF Solutions, Inc.
In our opinion, the accompanying consolidated balance sheets as of December 31, 2010 and 2009 and the related consolidated statements of operations, of stockholders' equity and comprehensive income (loss), and of cash flows for the years then ended present fairly, in all material respects, the financial position of PDF Solutions, Inc. and its subsidiaries at December 31, 2010 and 2009, and the results of their operations and their cash flows for the years then ended 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) as of and for the years ended December 31, 2010 and 2009 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 did not maintain, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in
Internal Control - Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) because material weaknesses in internal control over financial reporting related to lack of resources or expertise to provide reasonable assurance for the application of GAAP in non-routine or complex transactions, accounting for revenue transactions, and accounting for stock-based compensation transactions existed as of that date. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses referred to above are described in Management’s Report on Internal Control over Financial Reporting, appearing under Item 9A. We considered these material weaknesses in determining the nature, timing, and extent of audit tests applied in our audit of the 2010 consolidated financial statements, and our opinion regarding the effectiveness of the Company’s internal control over financial reporting does not affect our opinion on those consolidated financial statements. The Company’s management is responsible for these consolidated 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 report referred to above. 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 integrated audits. 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
Years Ended December 31, 2010, 2009 and 2008
1. Business and Significant Accounting Policies
PDF Solutions, Inc. (the “Company” or “PDF”), provides infrastructure technologies and services to improve yield and optimize performance of integrated circuits. The Company’s approach includes manufacturing simulation and analysis, combined with yield improvement methodologies to increase product yield and performance.
Basis of Presentation
— The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries after the elimination of all significant intercompany balances and transactions.
Reclassification —
Certain prior period cash flow amounts have been reclassified to conform to the current presentation. These reclassifications did not significantly impact any prior amounts of reported cash from or used by operating activities, investing activities or financing activities, and did not impact the balance sheet, stockholders' equity or results of operation.
Out-of-Period Adjustments
—
In the three months ended December 31, 2010, the Company recorded out-of-period adjustments to record additional sabbatical accrual for $76,000, stock-based compensation expense of $13,000, increase income tax provision of $67,000, reverse a restructuring accrual for $72,000 and increase the liability for uncertain tax positions by $256,000 that were incorrectly recorded in previous periods. The correction of these errors resulted in a decrease to the Company’s net income of $84,000 and $97,000 for the quarter and year ended December 31, 2010, respectively, and a decrease to other comprehensive loss of $256,000 for the year ended December 31, 2010. The resulting errors also decreased net income for the nine months ended September 30, 2010 by $13,000, and decreased net loss for the year ended December 31, 2009 by $97,000. Management has assessed the impact of these adjustments and does not believe that these amounts were material, either individually or in the aggregate, to any prior period financial statements, and the impact of correcting these errors in the three months ended December 31, 2010 is not material to the financial statements for the year ended December 31, 2010.
In the three months ended December 31, 2009, the Company recorded out-of-period adjustments to reverse a bonus accrual for $462,000, reverse stock-based compensation expense of $580,000 and record contract costs of $760,000 that were incorrectly deferred in previous periods. The correction of these errors resulted in a reduction to the Company's net loss of $282,000 and $672,000 for the quarter and year ended December 31, 2009, respectively. The resulting errors also increased net loss for the year ended December 31, 2008 by $672,000 and reduced net loss for the nine months ended September 30, 2009 by $390,000. Management has assessed the impact of these adjustments and does not believe that these amounts were material, either individually or in the aggregate, to any prior period financial statements, and the impact of correcting these errors in the three months ended December 31, 2009 is not material to the financial statements for the year ended December 31, 2009.
Significant Estimates
— The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates in these financial statements include stock-based compensation expense, allowances for doubtful accounts receivable, estimates for useful lives associated with long-lived assets, asset impairment charges, recoverability of intangible assets, restructuring charges, fair value of net assets held for sale and income taxes and tax valuation allowances. Actual results could differ from those estimates.
Certain Significant Risks and Uncertainties
— The Company operates in the dynamic semiconductor and software industries, and accordingly, can be affected by a variety of factors. For example, management of the Company believes that changes in any of the following areas could have a significant negative effect on the Company in terms of its future financial position, results of operations and cash flows: regulatory changes; fundamental changes in the technology underlying software technologies; market acceptance of the Company’s solutions; development of sales channels; litigation or other claims against the Company; the hiring, training and retention of key employees; successful and timely completion of development efforts; integration of newly acquired companies; and new product introductions by competitors.
Concentration of Credit Risk
— Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments, and accounts receivable. The Company maintains its cash and cash equivalents and investments with what it considers high credit quality financial institutions.
The Company primarily sells its technologies and services to companies in Asia, Europe and North America within the semiconductor industry. As of December 31, 2010, six customers accounted for 75% of the Company’s gross accounts receivable and four customers accounted for 60% of the Company’s revenues for 2010. As of December 31, 2009, six customers accounted for 77% of the Company’s gross accounts receivable and three customers accounted for 47% of the Company’s revenues for 2009. See Note 11 for further details. The Company does not require collateral or other security to support accounts receivable. To reduce credit risk, management performs ongoing credit evaluations of its customers’ financial condition. The Company maintains allowances for potential credit losses.
The allowance for doubtful accounts, which was based on management’s best estimates, could be adjusted in the near term from current estimates depending on actual experience. Such adjustments could be material to the consolidated financial statements.
41
Cash, Cash Equivalents and Short-term Investments
— The Company considers all highly liquid investments with an original maturity of 90 days or less or investments with a remaining maturity of 90 days or less at the time of purchase to be cash equivalents.
Investments with maturities greater than three months and less than one year are classified as short-term investments.
Accounts Receivable
— Accounts receivable includes amounts that are unbilled at the end of the period. Unbilled accounts receivable are determined on an individual contract basis and were approximately $6.0 million and $6.4 million at December 31, 2010 and 2009, respectively.
Property and Equipment
— Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the related asset as follows:
|
Computer and equipment
|
3 years
|
|
Software
|
3 years
|
|
Furniture, fixtures, and equipment
|
5-7 years
|
|
Leasehold improvements
|
Shorter of estimated useful life or term of lease
|
|
Assets acquired under capital lease
|
Shorter of estimated useful life or term of lease
|
Long-lived Assets
— The Company’s long-lived assets, excluding goodwill, consist of property and equipment and other acquired intangibles. The Company periodically reviews its long-lived assets for impairment
.
For assets to be held and used, the Company initiates its review whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset group may not be recoverable. Recoverability of an asset group is measured by comparison of its carrying amount to the expected future undiscounted cash flows that the asset group is expected to generate. If it is determined that an asset group is not recoverable, an impairment loss is recorded in the amount by which the carrying amount of the asset group exceeds its fair value.
Goodwill
— Goodwill is measured and tested for impairment on an annual basis and more frequently in certain circumstances. Accordingly, the Company has selected December 31 as the date to perform the annual testing requirements. The Company performs a two-step testing on goodwill impairment. The first step requires that the Company compare the estimated fair value of its single reporting unit to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value of its net assets, the Company is required to complete the second step of impairment test to determine the fair value of goodwill. Impairment is recorded if the carrying value of the goodwill exceeds its fair value.
As discussed in Note 11, the Company considers itself to be in one operating segment. In addition, the Company has determined that its operating segment is also its reporting unit as the operating segment comprises only a single component. To determine the reporting unit’s fair value, the Company used the income valuation approach. In determining its overall conclusion of reporting unit’s fair value, the Company also considers the estimated value derived from the market valuation approach as compared to the valuation under the income approach as one measure that the estimated fair value is reasonable.
The income approach provides an estimate of fair value based on discounted expected future cash flows. Estimates and assumptions with respect to the determination of the fair value of the Company’s reporting unit using the income approach include the Company’s operating forecasts, revenue growth rates, and risk-commensurate discount rates and costs of capital. The Company’s estimates of revenues and costs are based on historical data, various internal estimates and a variety of external sources, and are developed as part of the Company’s routine long-range planning process.
The market approach provides an estimate of the fair value of the Company’s reporting unit using various prices or market multiples applied to the reporting unit’s operating results and then applying an appropriate control premium, which is determined by considering control premiums offered as part of acquisitions in both the Company’s market segment and comparable market segments.
Revenue Recognition
— The Company derives revenue from two sources: Design-to-Silicon-Yield Solutions, which include Services and Software Licenses, and gainshare performance incentives.
Design-to-Silicon-Yield Solutions
— Revenues that are derived from Design-to-Silicon-Yield solutions come from services and software licenses. The Company recognizes revenue for each element of Design-to-Silicon-Yield solutions as follows:
Services
— The Company generates a significant portion of its Design-to-Silicon-Yield solutions revenues from fixed-price solution implementation service contracts delivered over a specific period of time. These contracts require reliable estimation of costs to perform obligations and the overall scope of each engagement. Revenues under contracts for solution implementation services are recognized as services are performed using the cost-to-cost percentage of completion method of contract accounting. Losses on solution implementation contracts are recognized in the period when they become probable. Revisions in profit estimates are reflected in the period in which the conditions that require the revisions become known and can be estimated.
42
On occasion, the Company licenses its software products that are not essential to the provision of these services as a component of its fixed-price service contract. In such instances, the software products are licensed to customers over a specified term of the agreement with support and maintenance to be provided over the license term.
In October 2009, the Financial Accounting Standards Board (“FASB”) amended the accounting standards for multiple-deliverable revenue arrangements to:
|
•
|
provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated, and how the consideration should be allocated;
|
|
•
|
require an entity to allocate revenue in an arrangement using best estimated selling prices (“BESP”) of deliverables if a vendor does not have vendor-specific objective evidence of selling price (“VSOE”) or third-party evidence of selling price (“TPE”); and
|
|
•
|
eliminate the use of the residual method and require an entity to allocate revenue using the relative selling price method.
|
The Company elected to early adopt this accounting standard on April 1, 2010 on a prospective basis for applicable transactions originating or materially modified after January 1, 2010.
The Company's adoption of this guidance does not generally change the accounting for the Company’s software transactions. It only affects certain revenue arrangements that include both solution implementation services and software products that are not essential to the provision of these services. The amount of product and service revenue recognized in a given period is affected by the Company’s judgment as to whether an arrangement includes multiple deliverables and, if so, its determination of the fair value of each deliverable. In general, VSOE does not exist for the Company’s solution implementation services and software products. Because its services and products include its unique technology, the Company is not able to determine TPE. Therefore, the Company will use BESP in its allocation of arrangement consideration. In determining BESP, the Company applies significant judgment as it weighs a variety of factors, based on the facts and circumstances of the arrangement. The Company typically arrives at an BESP for a product or service that is not sold separately by considering company-specific factors such as geographies, internal costs, gross margin objectives, pricing practices used to establish bundled pricing, and existing portfolio pricing and discounting.
After fair value is established for each deliverable, the total transaction amount is allocated to each deliverable based upon its relative fair value. Fees allocated to solution implementation services are recognized using the cost-to-cost percentage of completion method of contract accounting. Fees allocated to software and related support and maintenance are recognized under software revenue recognition guidance.
Prior to the adoption of this new accounting standard, under these arrangements, where VSOE existed for the support and maintenance element, the support and maintenance revenue was recognized separately over the term of the supporting period and the remaining fee was recognized as services are performed using the cost-to-cost percentage of completion method of contract accounting.
The impact on total revenues for the year ended December 31, 2010 from the adoption of this new accounting standard is shown in the following table (in thousands). Due to the nature of the arrangements, the Company is currently unable to determine the impact of the adoption of this new accounting standard on future revenues.

Software Licenses —
The Company also licenses its software products separately from its solution implementations. For software license arrangements that do not require significant modification or customization of the underlying software, software license revenue is recognized under the residual method when (1) persuasive evidence of an arrangement exists, (2) delivery has occurred, (3) the fee is fixed or determinable, (4) collectability is probable, and (5) the arrangement does not require services that are essential to the functionality of the software. When arrangements include multiple elements such as support and maintenance, consulting (other than for its fixed price solution implementations), installation, and training, revenue is allocated to each element of a transaction based upon its fair value as determined by the Company’s VSOE and such services are recorded as services revenue. VSOE for maintenance is generally established based upon negotiated renewal rates while VSOE for consulting, installation, and training services is established based upon the Company’s customary pricing for such services when sold separately. Revenue for software licenses with extended payment terms is not recognized in excess of amounts due. For software license arrangements that require significant modification or customization of the underlying software, the software license revenue is recognized as services are performed using the cost-to-cost percentage of completion method of contract accounting, and such revenue is recorded as services revenue.
Gainshare Performance Incentives
— When the Company enters into a contract to provide yield improvement services, the contract usually includes two components: (1) a fixed fee for performance by the Company of services delivered over a specific period of time; and (2) a gainshare performance incentives component where the customer may pay a variable fee, usually after the fixed fee period has ended. Revenue derived from gainshare performance incentives represents profit sharing and performance incentives earned based upon the Company’s customers reaching certain defined operational levels established in related solution implementation service contracts. Gainshare performance incentives periods are usually subsequent to the delivery of all contractual services and therefore have no cost to the Company. Due to the uncertainties surrounding attainment of such operational levels, the Company recognizes gainshare performance incentives revenue (to the extent of completion of the related solution implementation contract) upon receipt of performance reports or other related information from the customer supporting the determination of amounts and probability of collection.
Software Development Costs
— Costs for the development of new software products and substantial enhancements to existing software products are expensed as incurred until technological feasibility has been established, at which time any additional costs would be capitalized. Because the Company believes its current process for developing software is essentially completed concurrently with the establishment of technological feasibility, no costs have been capitalized to date.
Research and Development
— Research and development expenses are charged to operations as incurred.
Stock-Based Compensation
— Stock-based compensation is estimated at the grant date based on the award’s fair value and is recognized on a straight-line basis over the vesting periods of the applicable stock purchase rights and stock options, generally four years. As stock-based compensation expense recognized is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
Cash flows resulting from excess tax benefits for awards accounted are classified as financing cash flows.
The Company has elected to use the Black-Scholes-Merton option-pricing model, which incorporates various assumptions including volatility, expected life and interest rates. The expected volatility is based on the historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected life of the Company’s stock options. The expected life of an award is based on historical experience and on the terms and conditions of the stock awards granted to employees. The interest rate assumption is based upon observed Treasury yield curve rates appropriate for the expected life of the Company’s stock options.
Income Taxes
– The Company's provision for income tax comprises its current tax liability and change in deferred tax assets and liabilities. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements using enacted tax rates and laws that will be in effect when the difference is expected to reverse. Valuation allowances are provided to reduce deferred tax assets to an amount that in management’s judgment is more likely than not to be recoverable against future taxable income. No U.S. taxes are provided on earnings of non-U.S. subsidiaries, to the extent such earnings are deemed to be permanently invested.
The Company's income tax calculations are based on application of the respective U.S. federal, state or foreign tax laws. The Company’s tax filings, however, are subject to audit by the respective tax authorities. Accordingly, the Company recognizes tax liabilities based upon its estimate of whether, and the extent to which, additional taxes will be due when such estimates are more-likely-than-not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. To the extent the final tax liabilities are different than the amounts originally accrued, the increases or decreases are recorded as income tax expense or benefit in the consolidated statements of operations.
Net Income (Loss) Per Share
–
Basic net income (loss) per share is computed by dividing net income (loss) by weighted average number of common shares outstanding for the period (excluding outstanding stock options and shares subject to repurchase). Diluted net income (loss) per share is computed using the weighted-average number of common shares outstanding for the period plus the potential effect of dilutive securities which are convertible into common shares (using the treasury stock method), except in cases in which the effect would be anti-dilutive.
Dilutive potential common shares consist of incremental common shares issuable upon exercise of stock options, upon vesting of restricted stock units, contingently issuable shares for all periods and assumed issuance of shares under employee stock purchase plan. No dilutive potential common shares are included in the computation of any diluted per share amount when a loss from continuing operations was reported by the Company.

Foreign Currency Translation
— The functional currency of the Company’s foreign subsidiaries is the local currency for the respective subsidiary. The assets and liabilities are translated at the period-end exchange rate, and statements of operations are translated at the average exchange rate during the year. Gains and losses resulting from foreign currency translations are included as a component of other comprehensive income (loss). Gains and losses resulting from foreign currency transactions are included in the consolidated statement of operations.
Comprehensive Income (Loss)
— The Company reports, by major components and as a single total, the change in its net assets during the period from non-owner sources. Comprehensive income (loss) is presented within the consolidated statements of stockholders’ equity and comprehensive income (loss). Accumulated other comprehensive income as of December 31, 2010 and 2009 is comprised of the following components (in thousands):

Recent Accounting Pronouncements
—
In April 2010, the Financial Accounting Standards Board (“FASB”) amended its guidance on share-based payment awards with an exercise price denominated in the currency of a market in which the underlying equity security trades. The amendment clarifies that an employee share-based payment award with an exercise price denominated in the currency of a market in which a substantial portion of the entity’s equity securities trades shall not be considered to contain a condition that is not a market performance, or service condition. Therefore, an entity would not classify such an award as a liability if it is otherwise qualifies as equity. This amendment is effective for fiscal years and interim periods within those fiscal years beginning on or after December 15, 2010. The guidance will be effective for the Company’s interim period ending March 31, 2011. The Company does not expect the implementation to have a material impact on the Company’s consolidated financial statements.
In January 2010 the FASB amended its guidance on fair value measurements. This guidance 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 describe the reasons for the transfers. This guidance also requires disclosure of activity in Level 3 fair value measurements. The new disclosures and clarifications of the existing disclosures are effective for interim and annual 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. Those disclosures are effective for fiscal year beginning after December 15, 2010, and the interim periods within those fiscal years. The Company adopted the guidance related to Level 1 and Level 2 fair value measurements on January 1, 2010. The guidance for Level 3 fair value measurements and disclosures will be effective for the Company’s interim period ending March 31, 2011. The adoption of this standard did not, and is not expected to, have a material impact on the Company’s consolidated financial statement disclosures.
In October 2009, the FASB amended its guidance on software revenue recognition in relation to revenue arrangements that include software elements. This standard removes from the scope of software revenue recognition accounting, revenue arrangements for tangible products that contain both software and non-software components that function together to deliver the tangible products’ essential functionality. It also amends the determination of how arrangement consideration should be allocated to deliverables in a multiple-deliverable revenue arrangement. This update is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010 and allows for early adoption. The Company elected to early adopt this guidance with prospective application effective April 1, 2010. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

During the fourth fiscal quarter of 2008, the Company observed impairment indicators relating to their long-lived assets, including the trading of its common stock below its book value, the anticipated future decline in its operational results, and a further deterioration in the semiconductor industry in which the Company operates, which triggered the necessity of impairment test as of December 31, 2008. As such, the Company assessed the recoverability of its long-lived assets by comparing the carrying value of those intangible assets to the undiscounted cash flows of the asset group. The analysis indicated that the carrying value of those assets exceeded the undiscounted cash flows. As such, the Company determined that certain of the acquired intangible assets were impaired. The Company measured the amount of impairment by calculating the amount by which the carrying value of the assets exceeded their estimated fair values, which were based on projected discounted future net cash flows. As a result of this impairment analysis, the Company recorded an impairment of $6.3 million during the fourth fiscal quarter of 2008. During the years ended December 31, 2010 and 2009, there were no indicators of impairment related to the Company’s intangible assets.
During the year ended December 31, 2008, the Company completed its annual evaluation of the goodwill as of December 31, 2008 and determined that the goodwill was impaired. The Company recorded an impairment charge of $64.0 million for the year ended December 31, 2008. No goodwill impairment was recorded for the years ended December 31, 2010 and 2009 as the goodwill had been written down to zero as of December 31, 2008.

Debt
—As part of the acquisition of Si Automation S.A. (“SiA”), at the time of the acquisition, the Company assumed two separate debt agreements with a government-backed agency in France. In 2004, SiA obtained a €550,000 loan to cover research and development expenses. The loan did not carry interest and its repayment was conditioned on meeting certain revenue targets. During the three months ended September 30, 2009, an amendment to the agreement was executed to forgive €275,000 of the loan due to the partial success of the research project. The loan was fully repaid in 2009. The release of the debt was included in the “Interest and other income”. SiA also entered into a long-term debt agreement in 2005 for a total amount of €400,000. The debt carries a variable interest rate based on the three month average EURIBOR plus 160 basis points. As of December 31, 2010, such rate was 1.47%. The debt is reimbursable in 20 equal principal quarterly installments from January 2007 through October 2011. The debt agreement does not carry any financial covenant. As of December 31, 2010, total future minimum debt payments under the current debt agreement totaled $108,000, which will be payable through October 2011.
Indemnifications
— The Company generally provides a warranty to its customers that its software will perform substantially in accordance with documented specifications typically for a period of 90 days following delivery of its products. The Company also indemnifies certain customers from third-party claims of intellectual property infringement relating to the use of its products. Historically, costs related to these guarantees have not been significant. The Company is unable to estimate the maximum potential impact of these guarantees on its future results of operations.
Purchase obligations
— The Company has purchase obligations with certain suppliers for the purchase of goods and services entered in the ordinary course of business. As of December 31, 2010, total outstanding purchase obligations were $2.1 million which are primarily due within the next 12 months.
Indemnification of Officers and Directors
— As permitted by the Delaware general corporation law, the Company has included a provision in its certificate of incorporation to eliminate the personal liability of its officers and directors for monetary damages for breach or alleged breach of their fiduciary duties as officers or directors, other than in cases of fraud or other willful misconduct.
In addition, the Bylaws of the Company provide that the Company is required to indemnify its officers and directors even when indemnification would otherwise be discretionary, and the Company is required to advance expenses to its officers and directors as incurred in connection with proceedings against them for which they may be indemnified. The Company has entered into indemnification agreements with its officers and directors containing provisions that are in some respects broader than the specific indemnification provisions contained in the Delaware general corporation law. The indemnification agreements require the Company to indemnify its officers and directors against liabilities that may arise by reason of their status or service as officers and directors other than for liabilities arising from willful misconduct of a culpable nature, to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified, and to obtain directors’ and officers’ insurance if available on reasonable terms. The Company has obtained directors’ and officers’ liability insurance in amounts comparable to other companies of the Company’s size and in the Company’s industry. No payments were made during the years ended December 31, 2009 and 2008. During the year ended December 31, 2010, the Company made payments totaling $196,000, a portion of which was associated with these indemnification obligations. Since a maximum obligation of the Company is not explicitly stated in the Company’s Bylaws or in its indemnification agreements and will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the obligations cannot be reasonably estimated.
Litigation
— From time to time, the Company is subject to various claims and legal proceedings that arise in the ordinary course of business. Although the Company's management currently believes that the ultimate outcome of any of these claims and proceedings, individually and in the aggregate, will not have a material adverse effect on the Company's financial position or overall trends in results of operations, litigation is subject to inherent uncertainties. If an unfavorable ruling occurs in any of the legal proceedings described below, the Company's financial position and results of operations and cash flows could be negatively affected. The Company accrues for losses related to the litigation when the Company's management considers a potential loss probable and can reasonably estimate such loss in accordance with FASB requirements. With respect to each of the matters below, the Company's management has determined a potential loss is not probable at this time and, accordingly, no amount has been accrued at December 31, 2010. As the Company's management continues to monitor these matters, however, its determination could change and it may decide a different reserve is appropriate in the future.
Philip Steven Melman filed a complaint against the Company and its Chief Executive Officer on December 7, 2009 in the Superior Court for Santa Clara County. In the complaint, Mr. Melman alleges wrongful discharge based on discrimination, fraud, breach of contract and similar theories, in connection with the termination of Mr. Melman's employment with the Company. The complaint seeks compensatory and punitive damages, any other available remedies, as well as attorney's fees and costs. The Company believes that the complaint is without merit and intends to vigorously oppose it.
Global Software Services, Inc., a Palestinian corporation (“GSSI”), filed a complaint against the Company on February 16, 2010 in the Superior Court for Santa Clara County. In the complaint, GSSI alleged that the Company failed to pay GSSI amounts owed under a Professional Services Agreement pursuant to which GSSI was providing software-related development and support services to the Company. In addition, GSSI alleged that the Company interfered with GSSI’s business relationships and employee relationships and that the Company engaged in unfair business practices in violation of Business & Professions Code Section 17200. The complaint sought compensatory and punitive damages, disgorgement and restitution, injunctive relief and any other available equitable remedies, as well as attorney's fees and costs. On December 2, 2010, the court dismissed GSSI's action with prejudice.

Stock-based compensation is estimated at the grant date based on the award’s fair value and is recognized on a straight-line basis over the vesting periods of the applicable stock purchase rights and stock options, generally four years. As the Company maintains a full valuation allowance against its U.S. deferred tax assets, there are no income tax benefits recognized related to stock-based compensation expense. As stock-based compensation expense recognized is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
The Company has elected to use the Black-Scholes-Merton option-pricing model, which incorporates various assumptions including volatility, expected life and interest rates. The expected volatility is based on the historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected life of the Company’s stock options. The expected life of an award is based on historical experience and on the terms and conditions of the stock awards granted to employees. The interest rate assumption is based upon observed Treasury yield curve rates appropriate for the expected life of the Company’s stock options.
The fair value of equity awards granted was estimated on the date of grant with the following weighted average assumptions:

On December 31, 2010, the Company had in effect the following stock-based compensation plans:
Stock Plans
— In 2001, the Company terminated the 1996 and 1997 Stock Plans with respect to future option grants, and adopted the 2001 Stock Plan. Under the 2001 Stock Plan, on January 1 of each year starting with year 2002, the number of shares in the reserve will increase by the lesser of (1) 3,000,000 shares, (2) 5% of the outstanding common stock on the last day of the immediately preceding year, or (3) the number of shares determined by the board of directors. Under the 2001 Stock Plan, the Company may grant stock purchase rights and stock options to purchase shares of common stock to employees, directors and consultants. The exercise price for stock options must generally be at prices not less than the fair market value at the date of grant for incentive stock options. Stock options generally expire ten years from the date of grant and become vested and exercisable ratably over a four-year period. The 2001 Stock Plan will expire on June 12, 2011, unless amended by the stockholders before such time.
As of December 31, 2010, the Company had authorized 14.3 million shares of common stock for issuance and exercise of options, of which 5.8 million shares were available for grant at that date. As of December 31, 2010, there were no outstanding options that had been granted outside of the Plans.

On June 10, 2008, the Company filed a tender offer on Form SC TO-I (the "2008 Offer") with the SEC under which holders of options with exercise prices equal to or greater than $10.00 per share could tender their options in exchange for restricted stock rights granted under the 2001 Stock Plan based upon a 4.2 options to 1.0 restricted stock right exchange ratio. Restricted stock rights received in exchange for eligible options are subject to new vesting schedules, ranging from 15 months to 51 months, depending on when stock options exchanged were granted.
The Company completed the 2008 Offer on August 18, 2008. As a result, the Company accepted for exchange options to purchase an aggregate of 3.3 million shares of the Company’s common stock from 210 eligible participants, representing approximately 74% of the shares subject to options that were eligible to be exchanged in the 2008 Offer. Upon the terms and subject to the conditions set forth in the 2008 Offer, the Company issued restricted stock rights covering an aggregate of 793,000 shares of the Company’s common stock in exchange for the options surrendered pursuant to the 2008 Offer.
The fair value of the restricted stock rights awarded in the 2008 Offer was measured as the total of the unrecognized compensation cost of the original options tendered and the incremental compensation cost of the restricted stock rights awarded on August 18, 2008, the date of cancellation. The incremental compensation cost was measured as the excess of the fair value of the restricted stock rights awards over the fair value of the options immediately before cancellation based on the share price and other pertinent factors at that date.

On November 17, 2009, the Company filed a tender offer on Form SC TO-I (the “2009 Offer”) with the SEC under which holders of options with exercise prices equal to or greater than $4.75 per share could tender their options in exchange for restricted stock rights granted under the 2001 Stock Plan. The exchange ratio of option shares to restricted stock rights depended on the exercise price of the option as follows:

Restricted stock rights received in exchange for eligible options are subject to new vesting schedules equal to ¼ of the total number of restricted stock rights received on March 15 and September 15 in each of 2010 and 2011, subject to the holder’s continued service through each applicable vesting date.
On December 15, 2009, the Company completed the 2009 Offer. As a result, the Company accepted for exchange stock options to purchase an aggregate of 1.9 million shares of the Company's common stock from 131 eligible participants, representing approximately 60% of the shares subject to options that were eligible to be exchanged in the offer. Upon the terms and subject to the conditions set forth in the 2009 Offer the Company issued restricted stock rights covering an aggregate of 625,000 shares of the Company's common stock in exchange for the options surrendered pursuant to the 2009 Offer. The 2009 Offer was accounted for as a modification of the affected stock options but resulted in no significant incremental charge for the year ended December 31, 2009.

As of December 31, 2010, there was $2.6 million of total unrecognized compensation cost related to restricted stock rights. That cost is expected to be recognized over a weighted average period of 1.43 years. Restricted stock units do not have rights to dividends prior to vesting.
Employee Stock Purchase Plan
— In July 2001, the Company adopted an Employee Stock Purchase Plan (“Purchase Plan”) under which eligible employees can contribute up to 10% of their compensation, as defined in the Purchase Plan, towards the purchase of shares of PDF common stock at a price of 85% of the lower of the fair market value at the beginning of the offering period or the end of the purchase period. The Purchase Plan consists of twenty-four-month offering periods with four six-month purchase periods in each offering period. Under the Purchase Plan, on January 1 of each year, starting with 2002, the number of shares reserved for issuance will automatically increase by the lesser of (1) 675,000 shares, (2) 2% of the Company’s outstanding common stock on the last day of the immediately preceding year, or (3) the number of shares determined by the board of directors. At the annual meeting of stockholders on May 18, 2010, the Company's stockholders approved an amendment to the Purchase Plan to extend it through May 17, 2020. As of December 31, 2010, 3.9 million shares of the Company’s common stock have been reserved for issuance under the Purchase Plan. During 2010, 2009 and 2008, the number of shares issued were 588,000, 450,000 and 152,000, respectively, at a weighted average price of $1.33, $1.27 and $3.87 per share, respectively. As of December 31, 2010, 1.5 million shares were available for future issuance under the Purchase Plan. The weighted average estimated fair value of shares granted under the Purchase Plan during 2010, 2009 and 2008 was $1.55, $0.97 and $2.84 per share, respectively. For the year ended December 31, 2010, the Purchase Plan compensation expense was $395,000.
Stock Repurchase Program
— On October 29, 2007, the Board of Directors approved a program to repurchase up to $10.0 million of the Company’s common stock on the open market. The right to repurchase stock under this program expired on October 29, 2010. On October 19, 2010, the Board of Directors authorized an extension of, and an increase in, the stock repurchase program. Pursuant to such action taken by the Board of Directors, the stock repurchase program has been extended for two more years to October 29, 2012 and the aggregate amount available to repurchase has been increased to $10.0 million of the Company’s common stock.
As of December 30, 2010, 2.7 million shares had been repurchased at the average price of $3.46 per share under this program and $9.95 million remained available for future repurchases.

8. Restructuring
In 2008, the Company announced two restructuring plans to better allocate its resources to improve its operational results in light of current market conditions, one on April 29, 2008 and the other on October 28, 2008.
For the plan announced on April 29, 2008, the Company recorded restructuring charges of $1.5 million during the three months ended June 30, 2008, which primarily consisted of employee severance costs of $1.4 million. All severance costs and related fees were paid out and the activities were completed as of March 31, 2009.
For the plan announced on October 28, 2008, the Company recorded restructuring charges of $7.6 million, primarily consisting of employee severance costs of $4.8 million and facility exit costs of $2.6 million. The facility exit cost consists primarily of the cost of future obligations related to the locations. Discounted liabilities for future lease costs and the fair value of the related subleases of closed locations that are recorded is subject to adjustments as liabilities are settled. In assessing the discounted liabilities for future costs of obligations related to the locations, the Company made assumptions regarding the amounts of future subleases. If these assumptions or their related estimates change in the future, the Company may be required to record additional exit costs or reduce exit costs previously recorded. Exit costs recorded for each period presented include the effect of such changes in estimates. The following table summarizes the activities of these restructuring liabilities (in thousands):

As of December 31, 2010, the Company had federal and California net operating loss carry-forwards (“NOLs”) of approximately $0.4 million and $9.2 million, respectively. The federal loss can be carried forward 20 years and will begin expiring after 2029. The California losses can be carried forward 20 years for tax years beginning on or after January 1, 2008 and will begin expiring after 2031. The California NOLs are suspended through 2011.
In addition, as of December 31, 2010, the Company had federal and state research and experimental and other tax credit (“R&D credits”) carry-forwards of approximately $9.0 million and $9.4 million, respectively. The federal credits begin to expire after 2022, while the California credits have no expiration. The extent to which the federal and state credit carry forwards can be used to offset future tax liabilities, respectively, may be limited, depending on the extent of ownership changes within any three-year period as provided in the Tax Reform Act of 1986 and the California Conformity Act of 1987. In addition, the Company claimed foreign R&D credits of $0.4 million for the year ended December 31, 2010, which are refundable in the future if they are not used to offset future tax liabilities.
Based on the available objective evidence, both positive and negative, including the recent history of losses, forecasted U.S. pre tax income (loss), and the net operating losses that can be carried back to prior taxable years, management concluded as of December 31, 2008, that it is more likely than not that the Company’s deferred tax assets would not be fully realizable. The deferred tax assets balance as of December 31, 2010 and 2009 was $911,000 and $373,000, respectively. These amounts primarily represent foreign deferred tax assets relating to foreign R&D tax credits.

In accordance with the provisions of the accounting standard relating to accounting for uncertain tax positions, the Company classifies its liabilities for income tax exposures as long-term. The Company includes interest and penalties related to unrecognized tax benefits within the Company’s income tax provision. As of December 31, 2010 and 2009, the Company had accrued interest and penalties related to unrecognized tax benefits of $461,000 and $539,000, respectively. In the years ended December 31, 2010, 2009 and 2008, the Company recognized credits for interest and penalties related to unrecognized tax benefits in the consolidated statements of operations of $(78,000), $(23,000) and $(4,000), respectively.
The Company’s total amount of unrecognized tax benefits as of December 31, 2010 was $9.4 million, of which $2.7 million, if recognized, would affect the Company’s effective tax rate. The Company’s total amount of unrecognized tax benefits as of December 31, 2009 was $8.3 million, of which $2.7 million, if recognized, would affect the Company's effective tax rate. As of December 31, 2010, the Company has recognized a net amount of $3.7 million as long-term income taxes payable for unrecognized tax benefits in its consolidated balance sheet. The Company does not expect the change in unrecognized tax benefits over the next twelve months to materially impact its results of operations and financial position.
53
The Company conducts business globally and, as a result, files numerous consolidated and separate income tax returns in the U.S. federal, various state and foreign jurisdictions. Because the Company used some of the tax attributes carried forward from previous years to tax years that are still open, statutes of limitation remain open for all tax years to the extent of the attributes carried forward into tax year 2002 for federal and California tax purposes. The Company is currently subject to income tax examinations in France for 2009 and in California for 2006 and 2007. The Company is not subject to income tax examinations in any other of its major foreign subsidiaries’ jurisdictions.

Undistributed earnings of the Company’s foreign subsidiaries of $2.3 million are considered to be indefinitely reinvested and accordingly, no provision for federal and state income taxes has been provided thereon.
10. Net Income (Loss) Per Share
Basic net income (loss) per share is computed by dividing net income (loss) by weighted average number of common shares outstanding for the period (excluding outstanding stock options and shares subject to repurchase). Diluted net income (loss) per share is computed using the weighted-average number of common shares outstanding for the period plus the potential effect of dilutive securities which are convertible into common shares (using the treasury stock method), except in cases in which the effect would be anti-dilutive. There are no dilutive shares included during the year ended December 31, 2009 and 2008 due to the net loss for the period. Under the treasury stock method, the amount that the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of the tax benefits that would be recorded in additional paid-in capital when the award becomes deductible are assumed to be used to repurchase shares. The following is a reconciliation of the numerators and denominators used in computing basic and diluted net income (loss) per share (in thousands except per share amount):

11. Customer and Geographic Information
Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or group, in deciding how to allocate resources and in assessing performance.
The Company’s chief operating decision maker, the chief executive officer, reviews discrete financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance. Accordingly the Company considers itself to be in one operating segment, specifically the licensing and implementation of yield improvement solutions for integrated circuit manufacturers.

12. Fair Value
Fair value is the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The multiple assumptions used to value financial instruments are referred to as inputs, and a hierarchy for inputs used in measuring fair value is established, that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. These inputs are ranked according to a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels.
|
Level 1 -
|
Inputs are quoted prices in active markets for identical assets or liabilities.
|
|
Level 2 -
|
Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
|
|
Level 3 -
|
Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The Company holds investments in auction-rate securities (“ARS”), which are variable rate debt instruments whose interest rates are reset through a “Dutch” auction process at regular intervals, typically every 28 days. All ARS are backed by pools of student loans guaranteed by governmental agencies and private entities, and were rated AAA/Aaa at the date of acquisition. The liquidity and fair value of these securities has been reduced by the uncertainty in the credit markets and the exposure of these securities to the financial condition of bond insurance companies, as evidenced by the rating downgrade of MBIA (bond insurer on one of the Company’s ARS) from Aaa to A2, by Moody’s Investor Services on June 19, 2008. All ARS have failed to sell at auction since February 2008, and as a result, their interest rates were reset to the maximum LIBOR + 150 basis points. The only activity associated with these instruments since February 2008 was the repurchase of $500,000 of ARS at par by issuers. As a result of these auction failures, there was limited active market with observable prices for these securities. Therefore, the Company computed the fair value of these securities based on a discounted cash flow model, using significant level 3 inputs, to take into account the lack of liquidity. The cumulative impairment for these securities as of December 31, 2010 was $282,000, which is included in other comprehensive income. The Company does not believe that the student loans backing these securities, the principal of these assets, is at risk. Furthermore, the Company intends to hold these securities until the credit markets recover and these securities resume pricing at or near par and it is not more likely than not that the Company will be required to sell the securities before recovery of the principal. As a result, the Company recorded a temporary impairment to other comprehensive income and classified these securities as non-current investments. The valuation may be revised in future periods as market conditions evolve.
There was no change in the beginning and ending balance of assets measured at fair value on recurring basis using significant observable inputs (Level 3) during the year ended December 31, 2010.

13. Employee Benefit Plan
During 1999, the Company established a 401(k) tax-deferred savings plan, whereby eligible employees may contribute up to 15% of their eligible compensation with a maximum amount subject to IRS guidelines in any calendar year. Company contributions to this plan are discretionary; no such Company contributions have been made since the inception of this plan.
