Industry Background

Engineers and scientists use instrumentation to observe, understand, and manage the real-world phenomena, events and processes related to their industries or areas of expertise. Instrumentation systems measure and control electrical signals, such as voltage, current and power, as well as temperature, pressure, speed, flow, volume, torque, and vibration. Common general-purpose instruments include voltmeters, signal generators, oscilloscopes, data loggers, spectrum analyzers, cameras, and temperature and pressure monitors and controllers. Some traditional instruments are also highly application-specific, designed with fixed functionality to measure specific signals for particular vertical industries or applications. Instruments used for industrial automation applications include data loggers, strip chart recorders, programmable logic controllers (“PLCs”), and proprietary turn-key devices or systems designed to automate or control specific vertical applications.

Systems that perform measurement and control can be generally categorized as test, measurement, and embedded systems. These systems access real-world phenomena and are used throughout the research, design, manufacture, and service phases of a wide variety of products and applications.

Historically, engineers and scientists have used a variety of high-cost systems that operated independently and could be difficult to customize. Due to the limitations of these systems, adapting them to changing needs can be expensive and time-consuming, and users must often purchase multiple single-purpose instruments, controllers, loggers, and other peripherals.

Our Approach to Measurement and Automation

NI offers a different approach called graphical system design. This approach provides an integrated hardware and software platform for measurement and control systems that can be defined entirely by the customer.  This allows systems to more easily adapt to changing requirements and technologies over time. NI hardware and software also leverage commercially available technology whenever possible to deliver performance and cost benefits to our customers. Therefore these customer-defined systems are more flexible, with higher performance and lower costs, compared to traditional vendor-defined systems.

2  

NI equips engineers and scientists with tools that accelerate productivity, innovation and discovery. Our customers use our platform to develop test, measurement, control and embedded systems throughout various industries from design to production, in advanced research, and in teaching engineering and science.

Compared with traditional solutions, we believe our products and our graphical system design platform provide the following significant benefits to our customers:

Simpler, Faster Development

Customers face changing requirements and technologies while having to create more intelligent systems with fewer resources than ever. Our software-based approach simplifies the complexity of creating these systems by providing higher level interfaces to access changing technology and a way to easily upgrade through software while other fixed function systems require new hardware. When hardware changes are required, our modular, reconfigurable platforms enable users to easily change only the functions they need while preserving software continuity over time. In this way, the graphical system design platform-based approach accelerates the development of any system that needs measurement and control.

Performance and Efficiency

Our software brings the power of commercial computers, handheld devices, networks and the Internet to instrumentation and embedded devices. With features such as graphical programming, automatic code generation, graphical tools libraries, ready-to-use example programs, libraries of specific instrumentation functions, and the ability to deploy applications on a range of platforms, scientists and engineers can quickly build a system that meets individual application needs. Because the continuous performance improvement of personal computers (“PC”), Field Programmable Gate Arrays (“FPGA”) and networking technologies are the core platforms for our approach, scientists and engineers can quickly realize direct performance benefits,  faster execution for measurement and automation applications, shorter test times, faster automation, higher performing embedded systems and higher manufacturing throughput.

Modularity, Reusability and Reconfigurability

Our products include reusable hardware and software modules to provide considerable flexibility in configuring systems. This ability to reconfigure measurement and automation systems allows users to quickly adapt their systems to new and changing needs, eliminate duplicated programming efforts, and ultimately improve their efficiency and productivity. In addition, these features help protect both hardware and software investments against obsolescence.

Lower Total Solution Cost

NI solutions offer price to performance and energy-efficiency advantages over traditional proprietary systems. Graphical system design allows customers to equip powerful industry-standard computers, with reusable system design software and modular cost-effective hardware. In addition, these systems give engineers and scientists the flexibility and portability to adapt to changing needs, while offering a smaller form factor that occupies less space on the manufacturing floor and consumes less energy than traditional instrumentation equipment.

Products, Technology and Services

We offer an extensive line of measurement and control products to work either separately, as stand-alone products or as an integrated solution; however, customers generally purchase our software and hardware together. We believe that the flexibility, functionality and ease of use of our system design software promotes sales of our other software and hardware products. We offer volume licensing that helps customers maximize their software investment by reducing total cost of ownership and simplifying their software budgeting and purchasing.

System Design Software

For more than 25 years, NI has invested in its flagship software product, LabVIEW, which the company believes is the ultimate system design software for measurement and control. LabVIEW promotes problem-solving, accelerates productivity, and empowers innovation. With LabVIEW, users program graphically and can design custom virtual instruments by connecting icons with software wires to create “block diagrams” which are natural design notations for scientists and engineers. Users can customize front panels with knobs, buttons, dials and graphs to emulate control panels of instruments or add custom graphics to visually represent the control and operation of processes.

LabVIEW is a comprehensive development environment with the hardware integration and wide-ranging compatibility that engineers and scientists need to design and deploy measurement and control systems. The LabVIEW programming environment is graphical, with engineering-specific libraries of software functions and hardware interfaces. It also offers data analysis, visualization, and sharing features. Engineers and scientists can bring their vision to life with LabVIEW, and have access to a vast ecosystem of partners and technology alliances, and a global and active user community. When customers use LabVIEW, combined with the modular hardware approach with NI data acquisition, NI CompactRIO and PCI Extensions for Instrumentation (“PXI”) platforms, they are able to quickly integrate system components and do their jobs faster, more efficiently, and at a lower cost.

LabVIEW Real-Time and LabVIEW FPGA are strategic modular software add-ons to LabVIEW. With LabVIEW Real-Time, the user can easily configure their application program to execute using a real-time operating system kernel instead of the Windows operating system, so users can easily build their solutions. In addition, with LabVIEW Real-Time, users can easily configure their programs to operate remotely on embedded processors in PXI-based systems, on embedded processors inside NI CompactRIO distributed I/O systems, or on processors embedded on plug-in PC data acquisition boards. With LabVIEW FPGA, the user can configure their application to execute directly in silicon via a FPGA residing on one of our reconfigurable I/O hardware products. LabVIEW FPGA allows users to build their own highly specialized, custom hardware devices for ultra high-performance requirements or for unique or proprietary measurement or control protocols.

Programming Tools

In addition to LabVIEW, NI offers LabWindows/CVI and Measurement Studio as alternative programming environments.  LabWindows/CVI users use the conventional, text-based programming language of C for creating test and control applications. Measurement Studio consists of measurement and automation add-on libraries and additional tools for programmers who prefer Microsoft’s Visual Basic, Visual C++, Visual C#, and Visual Studio.NET development environments.

Application Software

NI offers a suite of software products, including NI TestStand, NI VeriStand, NI DIAdem and NI Multisim, which are complimentary to LabVIEW.

NI TestStand. NI TestStand is targeted for test and measurement (“T&M”) applications in a manufacturing environment. NI TestStand is a test management environment for organizing, controlling, and running automated prototype, validation, and manufacturing test systems. It also generates customized test reports and integrates product and test data across the customers’ enterprise and across the Internet. NI TestStand manages tests that are written in LabVIEW, LabWindows/CVI, Measurement Studio, C and C++, and Microsoft Visual Basic, so test engineers can easily share and re-use test code throughout their organization and from one product to the next. NI TestStand is a key element of our strategy to broaden the reach of our application software products across the corporate enterprise.

NI VeriStand. NI VeriStand is a ready-to-use software environment for configuring real-time testing applications, including hardware-in-the-loop (“HIL”) test systems.

We believe our prominence in the higher education area can contribute to our future success because students gain experience using our products before they enter the work force.

Sales and Distribution

We sell our software and hardware products primarily through a direct sales organization. We also use independent distributors, OEMs, VARs, system integrators and consultants to market our products. We source a substantial majority of our sales throughout the world from our manufacturing, warehousing and distribution facilities in Debrecen, Hungary and Penang, Malaysia. We have sales offices in the U.S. and sales offices and distributors in key international markets. Sales outside of the U.S. accounted for approximately 62%, 63% and 63%, of our revenues in 2013, 2012 and 2011, respectively. The vast majority of our foreign sales are denominated in the customers’ local currency, which exposes us to the effects of changes in foreign currency exchange rates. We expect that a significant portion of our total revenues will continue to be derived from international sales. (See Note 13 – Segment information of Notes to Consolidated Financial Statements for details concerning the geographic breakdown of our net sales, operating income, interest income and long-lived assets.)

We believe the ability to provide comprehensive service and support to our customers is an important factor in our business. We permit customers to return products within 30 days from receipt for a refund of the purchase price less a restocking charge. Our hardware products are generally warranted against defects in materials and workmanship for one year from the date we ship the products to our customers. Historically, warranty costs and returns have not been material.

The marketplace for our products dictates that many of our products be shipped very quickly after an order is received. As a result, we are required to maintain significant inventories. Therefore, inventory obsolescence is a risk for us due to frequent engineering changes, shifting customer demand, the emergence of new industry standards and rapid technological advances including the introduction by us or our competitors of products embodying new technology. We strive to mitigate this risk by monitoring inventory levels against product demand and technological changes. Additionally, many of our products have interchangeable parts and many have long lives. There can be no assurance that we will be successful in these efforts in the future.

Our foreign operations are subject to certain risks set forth on page 13 under “We are Subject to Various Risks Associated with International Operations and Foreign Economies.”

See discussion regarding fluctuations in our quarterly results and seasonality in ITEM 1A, Risk Factors, “Our Revenues are Subject to Seasonal Variations.”

Competition

The markets in which we operate are characterized by intense competition from numerous competitors, some of which are divisions of large corporations having far greater resources than we have, and we may face further competition from new market entrants in the future. A key competitor is Agilent Technologies Inc. (“Agilent”). In September of 2013, Agilent announced plans to separate into two publicly traded companies, one will retain the Agilent name as well as the life sciences, diagnostics and chemical analysis businesses and the other will be comprised of the electronic measurement (“EM”) business. The Agilent EM business offers hardware and software products that provide solutions that directly compete with our virtual instrumentation products including its own line of PXI based hardware. The Agilent EM business continues to aggressively advertise and market products that are competitive with our products and we believe the Agilent EM business continues to hold a strong position in the instrumentation business and any changes in its marketing strategy or product offerings, whether before or after the announced separation, could have a material adverse effect on our operating results. We cannot predict the impact that the Agilent separation will have on the markets that we serve.

We believe our ability to compete successfully depends on a number of factors both within and outside our control, including:

· general market and economic conditions;

· our ability to maintain and grow our business with our larger customers;

· our ability to meet the volume and service requirements of our larger customers;

· industry consolidation, including acquisitions by our competitors;

· success in developing new products;

· timing of our new product introductions;

· new product introductions by competitors;

· the ability of competitors to more fully leverage low cost geographies for manufacturing and/or distribution;

· product pricing;

· effectiveness of sales and marketing resources and strategies;

· adequate manufacturing capacity and supply of components and materials;

· efficiency of manufacturing operations;

· strategic relationships with our suppliers;

· product quality and performance;

· protection of our products by effective use of intellectual property laws;

· the financial strength of our competitors;

· the outcome of any future litigation or commercial dispute;

· barriers to entry imposed by competitors with significant market power in new markets; and,

· government actions throughout the world.

We currently believe that we compete effectively with respect to the foregoing factors; however, there can be no assurance that we will be able to compete successfully in the future.

Research and Development

We believe that our long-term growth and success depends on delivering high quality hardware and software products on a timely basis. We focus our research and development efforts on enhancing existing products and developing new products that incorporate appropriate features and functionality to be competitive with respect to technology and price/performance characteristics.

Our research and development staff strives to build quality into our products at the design stage in an effort to reduce overall development and manufacturing costs. Our research and development staff also designs proprietary application specific integrated circuits (“ASICs”), many of which are designed for use in several of our different products. The goal of our ASIC design program is to further differentiate our products from competing products, to improve manufacturability and to reduce costs. We seek to reduce our time to market for new and enhanced products by sharing our internally developed hardware and software components across multiple products.

As of December 31, 2013, we employed 2,085 people in product research and development. Our research and development expenses were $235 million, $223 million and $199 million for 2013, 2012 and 2011, respectively.

Intellectual Property

We rely on a combination of patent, trade secret, copyright and trademark law, contracts and technical measures to establish and protect our proprietary rights in our products. As of December 31, 2013, we held 765 U.S. patents (762 utility patents and 3 design patents) and 27 patents in foreign countries (25 patents registered in Europe in various countries; and 2 patents in Japan), and had 211 patent applications pending in the U.S. and foreign countries. 231 of our issued U.S. patents are software patents related to LabVIEW, and cover fundamental aspects of the graphical programming approach used in LabVIEW. Our patents expire from 2014 to 2032. The expiration of any patents in the short term is not expected to have any significant negative impact on our business. No assurance can be given that our pending patent applications will result in the issuance of patents. We also own certain registered trademarks in the United States and abroad. See further discussion regarding risks associated with our patents in ITEM 1A, Risk Factors, “Our Business Depends on Our Proprietary Rights and We are Subject to Intellectual Property Litigation.”

Manufacturing and Suppliers

We manufacture a substantial majority of our products at our facilities in Debrecen, Hungary and Penang, Malaysia. Additional production, primarily RF products and of low volume, complex or newly introduced products is done in Austin, Texas. In 2014, our site in Malaysia is expected to produce approximately 20% to 30% of our global production. This production is being generated by transferring existing products from our Hungarian production facility in support of anticipated growth in our business and introducing new products directly into our Malaysian facility. Our site in Hungary is expected to produce approximately 65% to 75% of our remaining products. Our product manufacturing operations can be divided into four areas: electronic circuit card and module assembly; chassis and cable assembly; technical manuals and product support documentation; and software duplication. Most of the electronic circuit card assemblies, modules and chassis are manufactured in house, although subcontractors are used from time to time. The majority of our electronic cable assemblies are produced by subcontractors; however, we do manufacture some on an exception basis. Our software duplication, technical manuals and product support documentation is primarily produced by subcontractors.

Our manufacturing processes use large volumes of high-quality components and subassemblies supplied by various suppliers in the U.S., Europe and Asia. Several of these components, including custom ASICs and some RF or custom components, are available through limited sources. Any disruption of our supply of limited source components, whether resulting from business demand, quality, production or delivery problems, could adversely affect our ability to manufacture our products, which could in turn adversely affect our business and results of operations. See “Our Business is Dependent on Key Suppliers” at page 15 for additional discussion of the risks associated with limited source suppliers.

See “Our Manufacturing Operations are Subject to a Variety of Environmental Regulations and Costs” at page 18 for discussion of environmental matters as they may affect our business.

Backlog

Backlog is a measure of orders that are received but that are not shipped to customers at the end of a quarter. We typically ship products shortly following the receipt of an order. Accordingly, our backlog typically represents less than 5 days sales. Backlog should not be viewed as an indicator of our future sales.

Employees

As of December 31, 2013, we had 7,114 employees worldwide, including 2,085 in research and development, 3,269 in sales and marketing and customer support, 1,006 in manufacturing and 754 in administration and finance. None of our employees are represented by a labor union and we have never experienced a work stoppage. We consider our employee relations to be good. For fifteen consecutive years, from 1999 to 2014, we have been named among the 100 Best Companies to Work for in America according to FORTUNE magazine. Also, for the third consecutive year, from 2011 to 2013, we were ranked among the top 25 of the World’s Best Multinational Workplaces according to Great Place to Work.

ITEM 1A.    RISK FACTORS  

Uncertain Global Economic Conditions Could Materially Adversely Affect Our Business and Results of Operations.  Our operations and performance are sensitive to fluctuations in general economic conditions, both in the U.S. and globally. Uncertainty about global economic conditions poses a risk as consumers and businesses may postpone spending in response to tighter credit, unemployment, negative financial news, volatile foreign currency markets and declines in income or asset values. For example, the continuing uncertainty regarding the debt limit for the U.S. federal government or the recent uncertainty and currency volatility in emerging economies, could increase volatility in domestic and foreign markets, could adversely affect the liquidity of our investments in U.S Treasuries, our investment in German government bonds and the liquidity of our money market funds. In addition, such uncertainty could cause declines in consumer and business confidence. These domestic and global economic uncertainties could have a material adverse effect on demand for our products and our operating results. Other factors that could adversely influence demand include increases in fuel and other energy costs, unemployment, labor and healthcare costs, access to credit, consumer and business confidence, and other macroeconomic factors affecting spending behavior.

Historically, our business cycles have generally followed the expansion and contraction cycles in the global industrial economy as measured by the PMI. In the three months ended December 31, 2013, the average of the PMI was 52.8 and the average of the new order element of the PMI was 54.2, both indicating expansion. For January 2014, the most recent PMI reading was 52.9, slightly above the most recent quarterly average but slightly below the December 2013 reading of 53.0. For January 2014, the new order element of the PMI was 54.3, also slightly above the most recent quarterly average, but lower than the December 2013 new order element reading of 54.4. During the three month period ended December 31, 2013, the PMI in the U.S. and the Eurozone maintained readings above 50. We are unable to predict whether the industrial economy, as measured by the PMI, will remain above the neutral reading of 50, strengthen or contract during 2014. If the industrial economy as measured by the PMI begins to contract, it could have an adverse effect on the spending patterns of businesses including our current and potential customers which could adversely affect our revenues and result of operations.

10  

Our Product Revenues are Dependent on Certain Industries.Sales of our products are dependent on customers in certain industries, particularly the telecommunications, semiconductor, consumer electronics, automotive, automated test equipment, defense and aerospace industries. As we have experienced in the past, and as we may continue to experience in the future, downturns characterized by diminished product demand in any one or more of these industries may result in decreased sales, and a material adverse effect on our operating results. For example,personal computer (“PC”) shipments declined every quarter during 2013. Continued weakness or further contraction in PC shipments in 2014 could have a material negative impact on our business as it may negatively impact the spending and investment patterns of many of the customers we serve across various industries and regions as many of our products allow our customers to equip industry-standard computers with our system design software and modular hardware.

Orders With a Value of Greater than One Million Dollars Expose Us to Significant Additional Business and Legal Risks that Could Have a Material Adverse Impact on our Business, Results of Operations and Financial Condition. In recent years, we have made a concentrated effort to increase our revenue through the pursuit of orders with a value greater than $1.0 million. During the years ended December 31, 2013, 2012 and 2011, we received $37 million, $76 million and $12 million in new orders from our largest customer, respectively. During the years ended December 31, 2013, 2012 and 2011, we recognized net revenue of $35 million, $68 million and $10 million from these orders, respectively. The timing and amount of these orders is unpredictable and therefore causes unusual variations in the trends of our business. Also, these types of orders expose us to significant additional business and legal risks compared to smaller orders. These very large customers frequently require contract terms that vary substantially from our standard terms of sale. These orders can be accompanied by critical delivery commitments and severe contractual liabilities can be imposed on us if we fail to provide the quantity of product at the required delivery times. These customers may also impose product acceptance requirements and product performance evaluations which create uncertainty with respect to the timing of our ability to recognize revenue from such orders. In addition, these larger orders are more volatile, are subject to greater discount variability and may contract at a faster pace during an economic downturn. These contracts may also have supply constraint requirements which mandate that we allocate large product inventories for a specific contract. These inventory requirements expose us to higher risks of inventory obsolescence and can adversely impact our ability to provide adequate product supply to other customers.

Fulfillment of these contracts can severely challenge our supply chain capabilities at the component acquisition, assembly and delivery stages. Our contracts with such customers may allow the customer to cancel or delay orders without liability which exposes our business and financial results to significant risk. These contracts can require us to develop specific product mitigation plans for product delivery constraints caused by unexpected or catastrophic situations to help assure quick production recovery. We can attempt to manage this risk but there can be no assurance that we will be successful in our efforts. These customers may demand most favored customer pricing, significant discounts, extended payment terms and volume rebates and such terms can adversely impact our revenues, margins, financial results and may also negatively impact our days sales outstanding as these orders become a larger proportion of our overall revenue. These customers may request broad indemnity obligations and large direct and consequential damage provisions in the event their contracts with us are breached, and these provisions may expose us to risk and liabilities in excess of our standard terms and conditions of sale. While we attempt to limit the number of contracts that contain the non-standard terms of sale described above and attempt to contractually limit our potential liability under such contracts, we have been and expect to be required to agree to some or all of such provisions to secure these customers and to continue to grow our business. Such actions expose us to significant additional risks which could result in a material adverse impact on our business, results of operations and financial condition. 

Revenue Derived from Large Orders Could Adversely Affect our Gross Margin and Could Lead to Greater Variability in our Quarterly Results.We define our large order business as orders with a value greater than $100,000. As a percent of our overall business, orders over $100,000 represented 21% of our total orders during 2013 and 2012. These orders may be more sensitive to changes in the global industrial economy, may be subject to greater discount variability, lower gross margins, and may contract at a faster pace during an economic downturn. Historically, our gross margins have been stable from period to period. To the extent that the amount of our revenue derived from larger orders increases in future periods, either in absolute dollars or as a percentage of our overall business, our gross margins could decline, could experience greater volatility and see a greater negative impact from future downturns in the global industrial economy. This dynamic may also have an adverse effect on the historical seasonal pattern of our revenues and our results of operations.

During the year ended December 31, 2013, we recognized net revenue of $35 million from our largest customer. The majority of this revenue relates to a new application in a highly competitive space. As a result, the gross margin for this revenue was significantly below our historical average. These types of orders also make managing inventory levels more difficult as we may have to build large quantities of inventory in anticipation of future demand that may not materialize. For example, during the first quarter of 2013, we increased our inventory by $19 million, primarily to meet anticipated demand from our largest customer. The actual demand from our largest customer was lower than we had anticipated and therefore had to take steps to reduce our inventory levels throughout the remainder of 2013.

11  

Our Current Domestic Cash Position May Not Be Sufficient to Fund our Domestic Cash Needs in the Next Twelve Months and We May Need to Seek Funding from External Sources or Repatriate Foreign Earnings.  At December 31, 2013, we had $393 million in cash, cash equivalents and short-term investments of which $324 million was held in operating and investment accounts of our foreign subsidiaries. On May 9, 2013, we entered into a Loan Agreement (the “Loan Agreement”) with Wells Fargo Bank, National Association (the “Lender”). The Loan Agreement provides for a $50 million unsecured revolving line of credit with a scheduled maturity date of May 9, 2018 (the “Maturity Date”). Proceeds of loans made under the Loan Agreement may be used for working capital and other general corporate purposes. We may choose to borrow funds against this line of credit in future periods in order to have sufficient domestic cash to fund continued dividends to our stockholders, to fund potential acquisitions or other domestic general corporate purposes without the need to repatriate foreign earnings. As of December 31, 2013, we had not utilized any amount available under this line of credit and we were in compliance with all applicable covenants in the Loan Agreement.

We may also seek to pursue additional financing or to raise additional funds by selling equity or debt to the public or in private transactions. If we elect to raise additional funds, we may not be able to obtain such funds on a timely basis on acceptable terms, if at all. If we raise additional funds by issuing additional equity or convertible debt securities, the ownership percentages of our existing stockholders would be reduced. In addition, the equity or debt securities that we issue may have rights, preferences or privileges senior to those of our common stock. We may also choose to repatriate foreign earnings which would be subject to the U.S. federal statutory tax rate of 35% and therefore, would likely have a material adverse effect on our effective tax rate and on our net income and earnings per share. We could also choose to reduce certain expenditures or payments of dividends or suspend our program to repurchase shares of our common stock. Historically, we have not had to rely on debt, public or private, to fund our operating, financing or investing activities.

We Operate in Intensely Competitive Markets.The markets in which we operate are characterized by intense competition from numerous competitors, some of which are divisions of large corporations having far greater resources than we have, and we may face further competition from new market entrants in the future. A key competitor is Agilent Technologies Inc. (“Agilent”). On September 19, 2013, Agilent announced plans to separate into two publicly traded companies, one will retain the Agilent name as well as the life sciences, diagnostics and chemical analysis businesses and the other will be comprised of the electronic measurement (“EM”) business. The Agilent EM business offers hardware and software products that provide solutions that directly compete with our virtual instrumentation products including its own line of PXI based hardware. The Agilent EM business continues to aggressively advertise and market products that are competitive with our products and we believe the Agilent EM business continues to hold a strong position in the instrumentation business and any changes in its marketing strategy or product offerings, whether before or after the announced separation, could have a material adverse effect on our operating results. We cannot predict the impact that the Agilent separation will have on the markets that we serve.

We believe our ability to compete successfully depends on a number of factors both within and outside our control, including: 

· our ability to maintain and grow our business with our very large customers;

· general market and economic conditions, particularly in the Euro zone;

· our ability to meet the volume and service requirements of our very large customers;

· industry consolidation, including acquisitions by our competitors; 

· success in developing new products; 

· timing of our new product introductions; 

· new product introductions by competitors; 

· the ability of competitors to more fully leverage low cost geographies for manufacturing and/or distribution; 

· product pricing; 

· effectiveness of sales and marketing resources and strategies; 

· adequate manufacturing capacity and supply of components and materials; 

· efficiency of manufacturing operations; 

· strategic relationships with our suppliers; 

· product quality and performance; 

· protection of our products by effective use of intellectual property laws; 

· the financial strength of our competitors; 

· the outcome of any future litigation or commercial dispute; 

· barriers to entry imposed by competitors with significant market power in new markets; and, 

· government actions throughout the world. 

There can be no assurance that we will be able to compete successfully in the future.

We Have Established a Budget and Variations From Our Budget Will Affect Our Financial Results.We have established an operating budget for 2014. Our budget was established based on the estimated revenue from sales of our products which are based on economic conditions in the markets in which we do business as well as the timing and volume of our new products and the expected penetration of both new and existing products in the marketplace. If demand for our products in 2014 is less than the demand we anticipated in setting our 2014 budget, our operating results could be negatively impacted. If we exceed the level of expenses established in our 2014 operating budget or if we cannot reduce budgeted expenditures in response to a decrease in revenue, our operating results could be adversely affected. Our spending could exceed our budgets due to a number of factors, including;

· less than expected capacity utilization of our new manufacturing facility in Penang, Malaysia;

· inefficiencies related to start-up operations of our new manufacturing facility in Penang, Malaysia;

· cost overruns related to training a new workforce for our new manufacturing facility in Penang, Malaysia;

· increased manufacturing costs resulting from component supply shortages or component price fluctuations; 

· additional marketing costs for new product introductions or for conferences and tradeshows; 

· the timing, cost or outcome of any future intellectual property litigation or commercial disputes;

· increased component costs resulting from vendors increasing their sales price; or 

· additional costs related to acquisitions, if any.  

Tax Law Changes in U.S. Could Have a Negative Impact on our Effective Tax Rate, Earnings and Results of Operations. In 2013, our effective tax rate benefited from the research tax credit in the U.S. This credit expired at the end of 2013 and unless it is extended, we will not be able to take this credit in 2014 or beyond which will have a material negative impact on our effective tax rate in future periods.

Our Quarterly Results are Subject to Fluctuations Due to Various Factors that May Adversely Affect Our Business and Result of Operations.  Our quarterly operating results have fluctuated in the past and may fluctuate significantly in the future due to a number of factors, including: 

· changes in the global economy or global credit markets, particularly in the Euro zone; 

· increasing concentration in the amount of revenue derived from very large orders and the pricing, margins, and other terms of such orders; 

· changes in capacity utilization including at our new facility in Malaysia; 

· fluctuations in foreign currency exchange rates; 

· changes in the mix of products sold; 

· the availability and pricing of components from third parties (especially limited sources); 

· the difficulty in maintaining margins, including the higher margins traditionally achieved in international sales; 

· changes in pricing policies by us, our competitors or suppliers; 

· the timing, cost or outcome of any future intellectual property litigation or commercial disputes; 

· delays in product shipments caused by human error or other factors; and, 

· disruptions in transportation channels.  

We are Subject to Various Risks Associated with International Operations and Foreign Economies. Our international sales are subject to inherent risks, including:  

· fluctuations in foreign currencies relative to the U.S. dollar;

· difficulties and the high tax costs associated with the repatriation of earnings;  

· fluctuations in local economies;  

· difficulties in staffing and managing foreign operations;  

· greater difficulty in accounts receivable collection;  

· costs and risks of localizing products for foreign countries;  

· unexpected changes in regulatory requirements;  

· tariffs and other trade barriers; and,  

· the burdens of complying with a wide variety of foreign laws.  

13  

In many foreign countries, particularly in those with developing economies, it is common to engage in business practices that are prohibited by U.S. regulations applicable to us such as the Foreign Corrupt Practices Act. Although we have policies and procedures designed to ensure compliance with these laws, there can be no assurance that all of our employees, contractors and agents, including those based in or from countries where practices which violate such U.S. laws may be customary, will not take actions in violation of our policies. Any violation of foreign or U.S. laws by our employees, contractors or agents, even if such violation is prohibited by our policies, could have a material adverse effect on our business. We must also comply with various import and export regulations. The application of these various regulations depends on the classification of our products which can change over time as such regulations are modified or interpreted. As a result, even if we are currently in compliance with applicable regulations, there can be no assurance that we will not have to incur additional costs or take additional compliance actions in the future. Failure to comply with these regulations could result in fines or termination of import and export privileges, which could have a material adverse effect on our operating results. Additionally, the regulatory environment in some countries is very restrictive as their governments try to protect their local economy and value of their local currency against the U.S. dollar.

The vast majority of our sales outside of North America are denominated in local currencies, and accordingly, the U.S. dollar equivalent of these sales is affected by changes in the foreign currency exchange rates. The change in exchange rates had the effect decreasing our consolidated sales by $7.3 million in the year ended December 31, 2013, and decreasing our consolidated sales by $20 million in the year ended December 31, 2012. Since most of our international operating expenses are also incurred in local currencies, the change in exchange rates had the effect of decreasing our consolidated operating expenses by $2.2 million in the year ended December 31, 2013, and decreasing our consolidated operating expenses by $5.8 million in the year ended December 31, 2012.  

During 2013, there was mixed, and at times, significant volatility in the exchange rates between the U.S. dollar and most of the major currencies in the markets in which we do business which included significant strengthening of the U.S. dollar against the Japanese yen. We cannot predict to what degree or how long this volatility in the foreign currency exchange markets will continue. In the past, we have noted that significant volatility in foreign currency exchange rates in the markets in which we do business has had a significant impact on the revaluation of our foreign currency denominated firm commitments, on our ability to forecast our U.S. dollar equivalent revenues and expenses and on the effectiveness of our hedging programs. In the past, these dynamics have also adversely affected our revenue growth in international markets and may pose similar challenges in the future. We recognize the local currency as the functional currency in virtually all of our international subsidiaries.

Our Tax Returns and Other Tax Matters are Subject to Examination by the U.S. Internal Revenue Service and Other Tax Authorities and Governmental Bodies and the Results of These Examinations Could Have a Material Adverse Effect on Our Financial Condition. We account for uncertainty in income taxes recognized in our financial statements using prescribed recognition thresholds and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on our tax returns. These uncertain tax positions are subject to examination by the U.S. Internal Revenue Service and other tax authorities. There can be no assurance as to the outcome of these examinations. If the ultimate determination of our taxes owed is for an amount in excess of amounts previously accrued, our operating results, cash flows, and financial condition could be materially adversely affected.

Tax Law Changes in Hungary Could Have a Negative Impact on our Effective Tax Rate, Earnings and Results of Operations.  The profit from our Hungarian operation benefits from the fact that it is subject to an effective income tax rate that is lower than the U.S. federal statutory tax rate of 35%. Our earnings in Hungary are subject to a statutory tax rate of 19%. The difference between this rate and the statutory U.S. rate of 35% resulted in income tax benefits of $8 million, $12 million and $16 million for the years ended December 31, 2013, 2012 and 2011, respectively. In addition, effective January 1, 2010, certain qualified research and development expenses became eligible for an enhanced tax deduction. The enhanced tax deduction for research and development expenses resulted in income tax benefits to us of $12 million, $17 million and $17 million for the years ended December 31, 2013, 2012 and 2011, respectively. This tax benefit may not be available in future years due to changes in political conditions in Hungary or changes in tax laws in Hungary and in the U.S. The reduction or elimination of these benefits in Hungary or future changes in U.S. law pertaining to the taxation of foreign earnings could result in an increase in our future effective income tax rate which could have a material adverse effect on our operating results. No countries other than Hungary had a significant impact on our effective tax rate. We have not entered into any advanced pricing or other agreements with the Internal Revenue Service with regard to any foreign jurisdictions.   

Our Income Tax Rate could be Affected by the Expiration of a Tax Holiday in Malaysia. Potential future profits from our new manufacturing facility in Penang, Malaysia are free of tax under a 15 year tax holiday effective January 1, 2013. If we fail to satisfy the conditions of the tax holiday, this tax benefit may be terminated early. The expiration of the tax holiday in Malaysia or future changes in U.S. law pertaining to the taxation of foreign earnings could have a material adverse effect on our operating results. 

14  

Our Success Depends on New Product Introductions and Market Acceptance of Our Products.The market for our products is characterized by rapid technological change, evolving industry standards, changes in customer needs and frequent new product introductions, and is therefore highly dependent upon timely product innovation. Our success is dependent on our ability to successfully develop and introduce new and enhanced products on a timely basis to replace declining revenues from older products, and on increasing penetration in domestic and international markets. As has occurred in the past and as may be expected to occur in the future, we have experienced significant delays between the announcement and the commercial availability of new products. Any significant delay in releasing new products could have a material adverse effect on the ultimate success of a product and other related products and could impede continued sales of predecessor products, any of which could have a material adverse effect on our operating results. There can be no assurance that we will be able to introduce new products in accordance with announced release dates, that our new products will achieve market acceptance or that any such acceptance will be sustained for any significant period. Failure of our new products to achieve or sustain market acceptance could have a material adverse effect on our operating results. Moreover, there can be no assurance that our international sales will continue at existing levels or grow in accordance with our efforts to increase foreign market penetration.

Our Revenues are Subject to Seasonal Variations.In previous years, our revenues have been characterized by seasonality, with revenues typically growing from the first quarter to the second quarter, being relatively constant from the second quarter to the third quarter, growing in the fourth quarter compared to the third quarter and declining in the first quarter of the following year from the fourth quarter of the preceding year. This historical trend has been affected and may continue to be affected in the future by broad fluctuations in the global industrial economy as well as the timing of new product introductions or any acquisitions. In addition, the increasing percentage of our revenue derived from very large orders could have a significant impact on our historical seasonal trends as these orders may be more sensitive to changes in the global industrial economy, may be subject to greater discount variability, lower gross margins, and may contract at a faster pace during an economic downturn. For example, in 2013, our sequential revenue growth in the fourth quarter as compared to the third quarter was 4% compared to the previous ten year average of 10%. Most of the weakness during the fourth quarter of 2013 was in larger orders, particularly in the emerging markets. Our historical seasonal variation could be significantly impacted if we cannot maintain or grow our business with our very large orders. We are seeing signs of economic uncertainty in emerging economies. If this uncertainty in the emerging markets continues or if it worsens or negatively affects other economic regions, it may have a material adverse effect on the seasonal patterns described above as well as on our overall results of operations and profitability. Our total operating expenses have in the past tended to increase in each successive quarter and have fluctuated as a percentage of revenue based on the seasonality of our revenue.

Concentrations of Credit Risk and Uncertain Conditions in the Global Financial Markets May Adversely Affect Our Business and Result of Operations.By virtue of our holdings of cash, investment securities and foreign currency derivatives, we have exposure to many different counterparties, and routinely execute transactions with counterparties in the financial services industry, including commercial banks and investment banks. Many of these transactions expose us to credit risk in the event of a default of our counterparties. We continue to monitor the stability of the financial markets, particularly those in the European region and have taken steps to limit our direct and indirect exposure to these markets; however, we can give no assurance that we will not be negatively impacted by any adverse outcomes in those markets. There can be no assurance that any losses or impairments to the carrying value of our financial assets as a result of defaults by our counterparties, would not materially and adversely affect our business, financial position and results of operations.

Our Business is Dependent on Key Suppliers and Distributors and Disruptions in these Businesses Could Adversely Affect our Business and Results of Operations.Our manufacturing processes use large volumes of high-quality components and subassemblies supplied by outside sources. Several of these components are only available through limited sources. Limited source components purchased include custom application specific integrated circuits (“ASICs”), chassis and other components. We have in the past experienced delays and quality problems in connection with limited source components, and there can be no assurance that these problems will not recur in the future. Accordingly, our failure to receive components from limited suppliers could result in a material adverse effect on our revenues and operating results. In the event that any of our limited source suppliers experience significant financial or operational difficulties due to adverse global economic conditions or otherwise, our business and operating results would likely be adversely impacted until we are able to secure another source for the required materials.

In some countries, we use distributors to support our sales channels. In the event that any of our distributors experience significant financial or operational difficulties due to adverse global economic conditions or if we experience disruptions in the use of these distributors, our business and operating results would likely be adversely impacted until we are able to secure another distributor or establish direct sales capabilities in the affected market.

A  Substantial Majority of our Manufacturing, Warehousing and Distribution Capacity is Located Outside of the United States. Our Hungarian and Malaysian manufacturing and warehouse facilities sourced a substantial majority of our sales in 2013 and are expected to source a substantial majority of our sales in 2014.

15  

In order to enable timely shipment of products to our customers we also maintain the vast majority of our inventory at our international locations. In addition to being subject to the risks of maintaining such a concentration of manufacturing capacity and global inventory, these facilities and their operations are also subject to risks associated with doing business internationally, including:

· changing and potentially unstable political environment in Hungary; 

· significant and frequent changes in the corporate tax law in Hungary; 

· the volatility of the Hungarian forint and the Malaysian ringgit relative to the U.S. dollar; 

· difficulty in managing manufacturing operations in foreign countries; 

· difficulty in achieving or maintaining product quality; 

· interruption to transportation flows for delivery of components to us and finished goods to our customers; and

· increasing labor costs. 

No assurance can be given that our efforts to mitigate these risks will be successful. Any failure to effectively deal with the risks above could result in an interruption in the operations of our facilities in Hungary or Malaysia which could have a material adverse effect on our operating results.

Our centralization of inventory and distribution from a limited number of shipping points is subject to inherent risks, including:

· burdens of complying with additional and/or more complex VAT and customs regulations; and, 

· concentration of inventory increasing the risks associated with fire, natural disasters and logistics disruptions to customer order fulfillment. 

Any difficulties with the centralization of our distribution or delays in the implementation of the systems or processes to support this centralized distribution could result in an interruption of our normal operations, including our ability to process orders and ship products to our customers. Any failure or delay in distribution from our facilities in Hungary and Malaysia could have a material adverse effect on our operating results.

The Completion of our Third Manufacturing Facility in Penang, Malaysia Could Adversely Affect our Gross Margin, Results of Operations and Earnings if Anticipated Demand is Not Achieved. Construction of our manufacturing and warehousing facility in Penang, Malaysia was completed in the fourth quarter of 2012. We believe this new facility will support our long term manufacturing and warehousing capacity needs. In 2014, our site in Malaysia is expected to produce approximately 20% to 30% of our global production.This production will mainly be from the transfer of existing production from our Hungarian production facility in support of anticipated growth in our business and introducing new products directly into our Malaysian facility. If demand for our products does not grow as expected or if it contracts in future periods, we will have excess warehousing and manufacturing capacity which will cause an increase in overhead that will likely negatively impact our gross margins and results of operations in future periods. In addition, we could experience other cost overruns with respect to our Malaysian facility including those associated with; 

· inefficiencies related to underutilization of this facility;

· cost overruns related to training a new workforce for this facility; or

· inefficient inventory management.

  We May Experience Component Shortages that May Adversely Affect Our Business and Result of Operations.As has occurred in the past and as may be expected to occur in the future, supply shortages of components used in our products, including limited source components, can result in significant additional costs and inefficiencies in manufacturing. If we are unsuccessful in resolving any such component shortages in a timely manner, we will experience a significant impact on the timing of revenue, a possible loss of revenue, and/or an increase in manufacturing costs, any of which would have a material adverse impact on our operating results.

We Rely on Management Information Systems and Interruptions in our Information Technology Systems Could Adversely Affect our Business.We rely on the efficient and uninterrupted operation of complex information technology systems and networks to operate our business. We rely on a primary global center for our management information systems and on multiple systems in branches not covered by our global center. As with any information system, unforeseen issues may arise that could affect our ability to receive adequate, accurate and timely financial information, which in turn could inhibit effective and timely decisions. Furthermore, it is possible that our global center for information systems or our branch operations could experience a complete or partial shutdown. A significant system or network disruption could be the result of new system implementations, computer viruses, security breaches, facility issues or energy blackouts. If such a shutdown or disruption occurred, it would adversely impact our product shipments and revenues, as order processing and product distribution are heavily dependent on our management information systems. Such an interruption could also result in a loss of our intellectual property or the release of sensitive competitive information or partner, customer or employee personal data. Any loss of such information could harm our competitive position, result in a loss of customer confidence, and cause us to incur significant costs to remedy the damages caused by the disruptions or security breaches. Accordingly, our operating results in such periods would be adversely impacted.

We are continually working to maintain reliable systems to control costs and improve our ability to deliver our products in our markets worldwide. Our efforts include, but are not limited to following: firewalls, antivirus protection, patches, log monitors, routine backups with offsite retention of storage media, system audits, data partitioning and routine password modifications. No assurance can be given that our efforts will be successful.

We are Subject to Risks Associated with Our Website.We devote significant resources to maintain our Website, ni.com, as a key marketing, sales and support tool and expect to continue to do so in the future. However, there can be no assurance that we will be successful in our attempt to leverage the Web to increase sales. Failure to properly maintain our website may interrupt normal operations, including our ability to provide quotes, process orders, ship products, provide services and support to our customers, bill and track our customers, fulfill contractual obligations and otherwise run our business which would have a material adverse effect on our results of operations. We host our Website internally. Any failure to successfully maintain our Website or any significant downtime or outages affecting our Website could have a material adverse impact on our operating results.

Adoption of Complex Health Care Legislation and Related Regulations and Financial Reform Could Increase our Operating Costs and Adversely Affect Our Result of Operations.The adoption of the Patient Protection and Affordable Care Act and the related reconciliation measure, the Health Care and Education Reconciliation Act of 2010, and the regulations resulting from such legislation has increased the costs of providing health care to our employees as well as caused us to incur additional administrative burdens and costs to comply with certain provisions of this legislation. We are unable to predict the ultimate amount or timing of any such increased costs or to what extent we may need to divert other resources to comply with various provisions of this legislation. Additionally, the Dodd-Frank Wall Street Reform and Consumer Protection Act has resulted in increased costs to us as a result of fees as well as incremental efforts we have had to undertake to comply with provisions of this law which are applicable to our derivative contracts or other financial instruments. In addition to the fees and efforts we have already incurred and undertaken to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act, we may incur additional costs in future periods as new rules are published and become effective.

Our Products are Complex and May Contain Bugs or Errors.  As has occurred in the past and as may be expected to occur in the future, our new software products or new operating systems of third parties on which our products are based often contain bugs or errors that can result in reduced sales or cause our support costs to increase, either of which could have a material adverse impact on our operating results.

Our Business Depends on Our Proprietary Rights and We Have Been Subject to Intellectual Property Litigation. Our success depends on our ability to obtain and maintain patents and other proprietary rights relative to the technologies used in our principal products. Despite our efforts to protect our proprietary rights, unauthorized parties may have in the past infringed or violated certain of our intellectual property rights. We from time to time engage in litigation to protect our intellectual property rights. In monitoring and policing our intellectual property rights, we have been and may be required to spend significant resources. We from time to time may be notified that we are infringing certain patent or intellectual property rights of others. There can be no assurance that any future intellectual property dispute or litigation will not result in significant expense, liability, injunction against the sale of some of our products, and a diversion of management’s attention, any of which may have a material adverse effect on our operating results.

Our Reported Financial Results May be Adversely Affected by Changes in Accounting Principles Generally Accepted in the United States.We prepare our financial statements in conformity with accounting principles generally accepted in the U.S. These accounting principles are subject to interpretation by the Financial Accounting Standards Board and the Securities and Exchange Commission. A change in these policies or interpretations could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the announcement of a change.

Our Business Depends on the Continued Service of Key Management and Technical Personnel.  Our success depends upon the continued contributions of our key management, sales, marketing, research and development and operational personnel, including Dr. Truchard, our Chairman and Chief Executive Officer, and other members of our senior management and key technical personnel. We have no agreements providing for the employment of any of our key employees for any fixed term and our key employees may voluntarily terminate their employment with us at any time. The loss of the services of one or more of our key employees in the future could have a material adverse effect on our operating results. We also believe our future success will depend upon our ability to attract and retain additional highly skilled management, technical, marketing, research and development, and operational personnel with experience in managing large and rapidly changing companies, as well as training, motivating and supervising employees. Failure to attract and retain a sufficient number of our key personnel could have a material adverse effect on our operating results.

17  

Our Manufacturing Operations are Subject to a Variety of Environmental Regulations and Costs that May Have a Material Adverse Effect on our Business and Results of our Operations.We must comply with many different governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in our manufacturing operations in the U.S., Hungary, and Malaysia. Although we believe that our activities conform to presently applicable environmental regulations, our failure to comply with present or future regulations could result in the imposition of fines, suspension of production or a cessation of operations. Any such environmental regulations could require us to acquire costly equipment or to incur other significant expenses to comply with such regulations. Any failure by us to control the use of or adequately restrict the discharge of hazardous substances could subject us to future liabilities.

Our Acquisitions are Subject to a Number of Related Costs and Challenges that Could Have a Material Adverse Effect on Our Business and Results of Operations.During the fourth quarter of 2012, we completed three acquisitions. We may in the future acquire additional complementary businesses, products or technologies. Achieving the anticipated benefits of an acquisition depends upon whether the integration of the acquired business, products or technology is accomplished efficiently and effectively. In addition, successful acquisitions generally require, among other things, integration of product offerings, manufacturing operations and coordination of sales and marketing and R&D efforts. These difficulties can become more challenging due to the need to coordinate geographically separated organizations, the complexities of the technologies being integrated, and the necessities of integrating personnel with disparate business backgrounds and combining different corporate cultures. The integration of operations following an acquisition also requires the dedication of management resources, which may distract attention from our day-to-day business and may disrupt key R&D, marketing or sales efforts. Our inability to successfully integrate any of our acquisitions could harm our business. The existing products previously sold by entities we have acquired may be of a lesser quality than our products and/or could contain errors that produce incorrect results on which users rely or cause failure or interruption of systems or processes that could subject us to liability claims that could have a material adverse effect on our operating results or financial position. Furthermore, products acquired in connection with acquisitions may not gain acceptance in our markets, and we may not achieve the anticipated or desired benefits of such transactions.

We Are Subject to the Risk of Product Liability Claims.Our products are designed to provide information upon which users may rely. Our products are also used in “real time” applications requiring extremely rapid and continuous processing and constant feedback. Such applications give rise to the risk that a failure or interruption of the system or application could result in economic damage or bodily harm. We attempt to assure the quality and accuracy of the processes contained in our products, and to limit our product liability exposure through contractual limitations on liability, limited warranties, express disclaimers and warnings as well as disclaimers contained in our “shrink wrap” license agreements with end-users. If our products contain errors that produce incorrect results on which users rely or cause failure or interruption of systems or processes, customer acceptance of our products could be adversely affected. Further, we could be subject to liability claims that could have a material adverse effect on our operating results or financial position. Although we maintain liability insurance for product liability matters, there can be no assurance that such insurance or the contractual limitations used by us to limit our liability will be sufficient to cover or limit any claims which may occur.

Provisions in Our Charter Documents and Delaware Law and Our Stockholder Rights Plan May Delay or Prevent an Acquisition of Us. Our certificate of incorporation and bylaws and Delaware law contain provisions that could make it more difficult for a third party to acquire us without the consent of our Board of Directors. These provisions include a classified Board of Directors, prohibition of stockholder action by written consent, prohibition of stockholders to call special meetings and the requirement that the holders of at least 80% of our shares approve any business combination not otherwise approved by two-thirds of the Board of Directors. Delaware law also imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. In addition, our Board of Directors has the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer. Our Board of Directors adopted a stockholders rights plan on January 21, 2004, pursuant to which we declared a dividend of one right for each share of our common stock outstanding as of May 10, 2004. This rights plan replaced a similar rights plan that had been in effect since our initial public offering in 1995. Unless redeemed by us prior to the time the rights are exercised, upon the occurrence of certain events, the rights will entitle the holders to receive upon exercise thereof shares of our preferred stock, or shares of an acquiring entity, having a value equal to twice the then-current exercise price of the right. The issuance of the rights could have the effect of delaying or preventing a change of control of us.

Compliance With Sections 302 and 404 of the Sarbanes-Oxley Act of 2002 is Costly and Challenging.  As required by Section 302 of the Sarbanes-Oxley Act of 2002, this Form 10-K contains our management’s certification of adequate disclosure controls and procedures as of December 31, 2013. This annual report on Form 10-K also contains a report by our management on our internal control over financial reporting including an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2013. This report on Form 10-K also contains an attestation and report by our external auditors with respect to the effectiveness of our internal control over financial reporting under Section 404. While these assessments and reports did not reveal any material weaknesses in our internal control over financial reporting, compliance with Sections 302 and 404 is required for each future fiscal year end. We expect that ongoing compliance with Sections 302 and 404 will continue to be costly and there can be no assurance that material weaknesses will not be identified in future periods. Any adverse results from such ongoing compliance efforts could result in a loss of investor confidence in our financial reports and have an adverse effect on our stock price.

PART II

ITEM 5.MARKET FOR THE REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock, $0.01 par value, began trading on The NASDAQ Stock Market under the symbol NATI effective March 13, 1995. Prior to that date, there was no public market for our common stock. The high and low closing prices for our common stock, as reported by Nasdaq for the two most recent fiscal years, are as indicated in the following table:

		High		Low
2013
First Quarter 2013	$	32.28	$	25.87
Second Quarter 2013		31.51		26.31
Third Quarter 2013		31.16		27.26
Fourth Quarter 2013		32.13		28.92
2012
First Quarter 2012	$	28.52	$	24.51
Second Quarter 2012		28.40		25.03
Third Quarter 2012		27.87		24.85
Fourth Quarter 2012		25.90		23.37

At the close of business on February 13, 2014, there were approximately 397 holders of record of our common stock and approximately 29,295 beneficial holders of our common stock.

We believe factors such as quarterly fluctuations in our results of operations, announcements by us or our competitors, technological innovations, new product introductions, governmental regulations, litigation, changes in earnings estimates by analysts or changes in our financial guidance may cause the market price of our common stock to fluctuate, perhaps substantially. In addition, stock prices for many technology companies fluctuate widely for reasons that may be unrelated to their operating results. These broad market and industry fluctuations may adversely affect the market price of our common stock.

Our cash dividend payments for the two most recent fiscal years, on a per share basis, are indicated in the following table. The dividends were paid on the dates set forth below:

		Dividend Amount
2013
March 11, 2013	$	0.14
June 3, 2013		0.14
September 3, 2013		0.14
December 3, 2013		0.14
2012
March 5, 2012	$	0.14
May 25, 2012		0.14
August 31, 2012		0.14
December 3, 2012		0.14

Our policy as to future dividends will be based on, among other considerations, our balance of domestic cash, our ability to obtain external financing through a line of credit, or by selling equity or debt securities to the public or to selected investors, our views on changes in tax rates applied to dividend income, potential future capital requirements related to research and development, expansion into new market areas, strategic investments and business acquisitions, share dilution management, legal risks, and challenges to our business model.

On January 30, 2014, our Board of Directors declared a quarterly cash dividend of $0.15 per common share, payable on March 10, 2014, to stockholders of record on February 18, 2014.

See Item 12 for information regarding securities authorized for issuance under our equity compensation plans.

Performance Graph

The following graph compares the cumulative total return to holders of NI’s common stock from December 31, 2008 to December 31, 2013  to the cumulative return over such period of the (i) Nasdaq Composite Index and (ii) Russell 2000 Index. We use the Russell 2000 Index due to the fact that we have not been able to identify a published industry or line of business index that we believe appropriately reflects our industry or line of business. We considered that our primary competitors are divisions of large corporations that have other significant business operations such that any index comprised of such competitors would not be reflective of our industry or line of business. We have also considered using a peer group index but do not believe such index is appropriate as we have not been able to identify other public companies that we believe are principally in the same line of business as we are.

The graph assumes that $100 was invested on December 31, 2008 in NI’s common stock and in each of the other two indices and the reinvestment of all dividends, if any. Stockholders are cautioned against drawing any conclusions from the data contained therein, as past results are not necessarily indicative of future performance.

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

The following “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Any statements contained herein regarding our future financial performance,  operations, or other activities (including, without limitation, statements to the effect that we “believe,” “expect,” “plan,” “may,” “will,” “project,” “continue,” or “estimate” or other variations thereof or comparable terminology or the negative thereof) should be considered forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements as a result of a number of important factors including those set forth under the heading “Risk Factors” beginning on page 10, and elsewhere in this Form 10-K. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. You should not place undue reliance on these forward-looking statements. We disclaim any obligation to update information contained in any forward-looking statement.

Overview  

National Instruments Corporation (“we”, “us” or “our”) designs, manufactures and sells tools to engineers and scientists that accelerate productivity, innovation and discovery. Our graphical system design approach to engineering provides an integrated software and hardware platform that speeds the development of systems needing measurement and control. We believe our long-term vision and focus on technology supports the success of our customers, employees, suppliers and stockholders. We sell to a large number of customers in a wide variety of industries. We have been profitable in every year since 1990. No single customer accounted for more than 3%, 7%, or 4% of our sales in 2013, 2012, or 2011, respectively.

The key strategies that management focuses on in running our business are the following:

Expanding our broad customer base  

We strive to increase our already broad customer base and to grow our large order business by serving a large market on many computer platforms, through a global marketing and distribution network. We also seek to acquire new technologies and expertise from time to time to open new opportunities for our existing product portfolio.  

Maintaining a high level of customer satisfaction  

To maintain a high level of customer satisfaction we strive to offer innovative, modular and integrated products through a global sales and support network. We strive to maintain a high degree of backwards compatibility across different platforms to preserve the customer’s investment in our products. In this time of intense global competition, we believe it is crucial that we continue to offer products with quality and reliability, and that our products provide cost-effective solutions for our customers.  

Leveraging external and internal technology  

Our product strategy is to provide superior products by leveraging generally available technology, supporting open architectures on multiple platforms and by leveraging our core technologies such as custom application specific integrated circuits (“ASICs”) across multiple products.  

We sell into test and measurement (“T&M”) and industrial/embedded applications in a broad range of industries and as such are subject to the economic and industry forces which drive those markets. It has been our experience that the performance of these industries and our performance are impacted by general trends in industrial production for the global economy and by the specific performance of certain vertical markets that are intensive consumers of measurement technologies. Examples of these markets are semiconductor capital equipment, telecom and mobile devices, consumer electronics, defense, aerospace and automotive. 

Leveraging a worldwide sales, distribution and manufacturing network  

We distribute our software and hardware products primarily through a direct sales organization. We also use independent distributors, OEMs, VARs, system integrators and consultants to market our products. We have sales offices in the U.S. and sales offices and distributors in key international markets. Sales outside of the Americas accounted for approximately 59% of our revenues in 2013, 60% of our revenues in 2012 and 60% of our revenues in 2011. The vast majority of our foreign sales are denominated in the customers’ local currency, which exposes us to the effects of changes in foreign currency exchange rates. We expect that a significant portion of our total revenues will continue to be derived from international sales. (See Note 13 - Segment information of Notes to Consolidated Financial Statements for details concerning the geographic breakdown of our net sales, operating income, interest income and long-lived assets).

We manufacture a substantial majority of our products at our facilities in Debrecen, Hungary and Penang, Malaysia. Additional production, primarily of RF products and of low volume, complex or newly introduced products is done in Austin, Texas. In 2014, our site in Malaysia is expected to produce approximately 20% to 30% of our global production. This production is being generated by transferring existing products from our Hungarian production facility in support of anticipated growth in our business and introducing new products directly into our Malaysian facility. Our site in Hungary is expected to produce approximately 65% to 75% of our remaining products. Our product manufacturing operations can be divided into four areas: electronic circuit card and module assembly; chassis and cable assembly; technical manuals and product support documentation; and software duplication. Most of the electronic circuit card assemblies, modules and chassis are manufactured in house, although subcontractors are used from time to time. The majority of our electronic cable assemblies are produced by subcontractors; however, we do manufacture some on an exception basis. Our software duplication, technical manuals and product support documentation is primarily produced by subcontractors.

Delivering high quality, reliable products

We believe that our long-term growth and success depend on delivering high quality software and hardware products on a timely basis. Accordingly, we focus significant efforts on research and development. We focus our research and development efforts on enhancing existing products and developing new products that incorporate appropriate features and functionality to be competitive with respect to technology, price and performance. Our success also is dependent on our ability to obtain and maintain patents and other proprietary rights related to technologies used in our products. We have engaged in litigation and where necessary, will likely engage in future litigation to protect our intellectual property rights. In monitoring and policing our intellectual property rights, we have been and may be required to spend significant resources.

  Our operating results fluctuate from period to period due to changes in global economic conditions and a number of other factors. As a result, we believe our historical results of operations should not be relied upon as indications of future performance. There can be no assurance that our net sales will grow or that we will remain profitable in future periods.

Current business outlook 

Many of the industries we serve have historically been cyclical and have experienced periodic downturns. In assessing our business, we consider the trends in the Global Purchasing Managers’ Index (“PMI”), global industrial production as well as industry reports on the specific vertical industries that we target. In the three months ended December 31, 2013, the average of the PMI was 52.8 and the average of the new order element of the PMI was 54.2, both indicating expansion. For January 2014, the most recent PMI reading was 52.9, slightly above the most recent quarterly average but slightly below the December 2013 reading of 53.0. For January 2014, the new order element of the PMI was 54.3, also slightly above the most recent quarterly average, but lower than the December 2013 new order element reading of 54.4. During the three month period ended December 31, 2013, the PMI in the US and the Eurozone maintained readings above 50. We are unable to predict whether the industrial economy, as measured by the PMI, will remain above the neutral reading of 50, strengthen or contract during 2014.

During the years ended December 31, 2013, 2012 and 2011, we received $37 million, $76 million and $12 million in new orders from our largest customer, respectively. During the years ended December 31, 2013, 2012 and 2011, we recognized net revenue of $35 million, $68 million and $10 million from these orders, respectively. The timing and amount of orders from such customers are unpredictable and therefore can cause unusual variations in the trends of our business. Some of these orders related to a new application in a highly competitive space. As a result, the gross margin for these orders was significantly below our historical average.  

The finish to our results for the fourth quarter of 2013 was weaker than expected, especially in the emerging markets.  For the fourth quarter, our orders were up 4% sequentially.  This is below our historical 10 year average sequential growth rate for the fourth quarter of approximately 10%.  Most of the weakness in the fourth quarter was in larger orders and may have been due to our customers having limited budgets for 2013, leaving little room for year-end spending. In the fourth quarter, we saw 3% year over year growth from orders under $20,000, 1% year over year growth of orders between $20,000 and $100,000, while orders over $100,000 were down 9% year over year. We believe there were two main drivers of the decline in our orders over $100,000; one was the expected decline in orders from our largest customer from $9 million in the fourth quarter of 2012 to $2.8 million in the fourth quarter of 2013, and the other was an unexpected 40% year over year decline of orders over $100,000 in emerging markets.

We are concerned with the economic trends coming from the emerging economies in early 2014. Of particular concern is the sharp devaluation of some of the currencies in these markets compared to the U.S. dollar and the broader impact this may have on economic activity within those economies and whether that may spread to other countries and the impact this may have on the PMI in future periods. If the industrial economy as measured by the PMI begins to contract, it could have an adverse effect on the spending patterns of businesses including our current and potential customers which could adversely affect our revenues and result of operations.

Results of Operations for the years ended December 31, 2013, 2012, and 2011 

Net Sales.  Our net sales were $1,173 million, $1,144 million, and $1,024 million for the years ended December 31, 2013, 2012, and 2011, respectively, an increase of 3% in 2013 following an increase of 12% in 2012. Product sales were $1,091 million, $1,055 million and $956 million for the years ended December 31, 2013, 2012 and 2011, respectively, an increase of 3% in 2013 following an increase of 10% in 2012. The increase in product sales during 2013 is attributed to increased sales volume and growth in the Americas and Europe, offset by decreased sales volume and contraction in East Asia. In 2012, the increase in product sales was attributed to increased sales volume in the Americas, East Asia and Emerging Markets, offset by a slight contraction in Europe. Software maintenance sales were $81 million, $87 million and $82 million for the years ended December 31, 2013, 2012 and 2011, respectively, a decrease of 7% in 2013 following an increase of 7% in 2012. The decrease in software maintenance sales during 2013 is attributed to year over year decreases in sales volume of post contract support services in four of the last five quarters. The increase in software maintenance sales during 2012 was attributed to increased sales volume of post contract support services. For the year ended December 31, 2012, our overall net sales were also positively impacted by our settlement agreement with GSA which was $1.3 million less than the amount previously accrued.

We did not take any significant action with regard to pricing during the years ended December 31, 2013, 2012 and 2011. 

Large orders, defined as orders with a value greater than $100,000, decreased by 3% year over year during 2013 compared to year over year growth of 67% in 2012. A significant amount of our large order growth in 2012 was the result of orders from our largest customer. During 2013, orders from this customer declined by $39 million. Excluding the impact of our largest customer, large orders grew by 22% and 23% during 2013 and 2012. Orders from our largest customer are discussed in more detail below. Large orders were 21%, 21%, and 14% of our total orders for the years ended December 31, 2013, 2012, and 2011, respectively. Larger orders are more volatile, are subject to greater discount variability and may contract at a faster pace during an economic downturn.

With respect to our largest customer, we are serving three different applications for this customer, each involving the use of LabVIEW and the NI PXI platform. Two of the applications we serve for this customer ramped up significantly for initial production in 2012, and as a result, the customer ordered far less units in 2013. The majority of orders from this customer in 2013 related to a new RF test application. During 2013, we received $37 million in new orders from our largest customer and recognized net revenue of $35 million from these orders. During 2012, we received new orders totaling $76 million from this customer, of which $68 million was recognized in revenue during 2012.

We do not typically maintain a large amount of order backlog as orders typically translate to sales quickly. As such, any weakness in orders typically has a pronounced impact on our net sales in the short term.

For the years ended December 31, 2013, 2012 and 2011, net sales in the Americas were $484 million, $455 million and $411 million, respectively, an increase of 6% in 2013 following an increase of 11% in 2012. Sales in the Americas, as a percentage of consolidated sales were 41%, 40% and 40%, respectively, over the three year period. In Europe, net sales were $318 million, $298 million and $309 million, respectively, an increase of 7% in 2013 following a decrease of 4% in 2012. Sales in Europe, as a percentage of consolidated sales were 27%, 26% and 30%, respectively, over the three year period. In East Asia, sales were $260 million, $283 million and $216 million, respectively, a decrease of 8% in 2013 following an increase of 31% in 2012. The 2013 sales trends in East Asia were adversely impacted by a decline in orders from our largest customer as discussed above, compared to the positive impact of this customer in 2012, as well as the impact of the decline of the value of the Japanese Yen. Net sales in East Asia, as a percentage of consolidated sales were 22%, 25% and 21%, respectively, over the three year period. We define East Asia to include greater China, Japan and Korea. In Emerging Markets, net sales were $111 million, $109 million and $89 million, respectively, an increase of 1.5% in 2013 following an increase of 22% in 2012. Sales in Emerging Markets, as a percentage of consolidated sales were 9%, 10% and 9%, respectively, over the three year period. We define Emerging Markets to include Southeast Asia, Africa, the Middle East, and the former Russian Republics.

We expect sales outside of the Americas to continue to represent a significant portion of our revenue. We intend to continue to expand our international operations by increasing our presence in existing markets, adding a presence in some new geographical markets and continuing the use of distributors to sell our products in some countries.  

Almost all of the sales made by our direct sales offices in the Americas (excluding the U.S.), Europe, East Asia, and Emerging Markets are denominated in local currencies, and accordingly, the U.S. dollar equivalent of these sales is affected by changes in foreign currency exchange rates. For the year ended December 31, 2013, in local currency terms, our consolidated net sales increased by $33 million or 3%, Americas sales increased by $30 million or 7%, European sales increased by $18 million or 6%, sales in East Asia decreased by $19 million or 7%, and sales in Emerging Markets increased by $4.7 million or 4%, compared to the year ended December 31, 2012. During this same period, the change in exchange rates had the effect of decreasing our consolidated sales by $7.3 million or 0.6%, with negligible impact in the Americas, increasing European sales by $3.9 million or 1.3%, decreasing East Asia sales by $7.2 million or 2.5%, and decreasing sales in Emerging Markets by $3.1 million or 3%.  

For 2012, in local currency terms, our total sales increased by $138 million or 13%, Americas sales increased by $45 million or 11%, European sales increased by $4.6 million or 1%, sales in East Asia increased by $63 million or 29%, and sales in Emerging Markets increased by $25 million or 28%. During this same period, the change in exchange rates had the effect of decreasing our total sales by $20 million or 2%, decreasing Americas sales by $1.8 million or 0.4%, decreasing European sales by $18 million or 6%, increasing East Asia by $4.0 million or 2% and decreasing Emerging Markets sales by $4.9 million or 6%.

To help protect against changes in U.S dollar equivalent value caused by fluctuations in foreign currency exchange rates of forecasted foreign currency cash flows resulting from international sales, we have instituted a foreign currency cash flow hedging program. We hedge portions of our forecasted revenue denominated in foreign currencies with average rate forward contracts. During 2013, these hedges had the effect of increasing our consolidated sales by $3.2 million. During 2012, these hedges had the effect of increasing our consolidated sales by $2.9 million. (See Note 4 - Derivative instruments and hedging activities of Notes to Consolidated Financial Statements for further discussion regarding our cash flow hedging program and its related impacted on our consolidated sales for 2013 and 2012). 

Gross Profit.For the years ended December 31, 2013, 2012 and 2011, gross profit was $867 million, $863 million and $783 million, respectively. As a percentage of sales, gross profit was 74%, 76% and 77% in 2013, 2012 and 2011, respectively. During 2013, our gross margin was negatively impacted by the incremental overhead related to our new manufacturing facility in Penang, Malaysia.  We continue to focus on cost control and cost reduction measures throughout our manufacturing cycle.

In the years ended December 31, 2013 and 2012, the change in exchange rates had the effect of increasing our cost of sales by $1.5 million and decreasing our cost of sales by $1.2 million, respectively. To help protect against changes in our cost of sales caused by a fluctuation in foreign currency exchange rates of forecasted foreign currency cash flows, we have a foreign currency cash flow hedging program. We hedge portions of our forecasted costs of sales denominated in foreign currencies with average rate forward contracts. During the years ended December 31, 2013 and 2012, these hedges had the effect of decreasing our cost of sales by $118,000 and decreasing our cost of sales by $402,000, respectively. (See Note 4 - Derivative instruments and hedging activities of Notes to Consolidated Financial Statements for further discussion regarding our cash flow hedging program and its related impacted on our consolidated sales for 2013 and 2012).

Operating Expenses. For the years ended December 31, 2013, 2012 and 2011, operating expenses were $769 million, $746 million and $670 million, respectively, an increase of 3% in 2013, following an increase of 11% in 2012. The increase in our operating expenses in 2013 was due to higher personnel related expenses of $30 million which included salaries, commissions, variable compensation and benefits. In addition, the overall increase in 2013 is attributed to higher expenses for building and equipment of $9 million. These increases were offset by a $10 million decrease in other operating expenses including travel, marketing, outside services and software development costs. Over the same period, the net impact of changes in foreign currency exchange rates decreased our operating expense by $2.2 million. In response to slowing growth in our net sales, we took steps to control our operating expenses throughout 2013 resulting in quarter over quarter sequential declines in operating expenses in three of the last four quarters.

During 2012, our operating expenses grew 16% during the first half of the year, compared to the first half of 2011 and grew by 8% during the second half of the year, compared to the second half of 2012. The 8% growth in the second half of the year includes an adjustment to the accrual related to our AWR acquisition of $6.8 million as a result of AWR’s performance exceeding our prior expectations. Overall, the increase in our operating expenses in 2012 was due to higher personnel related expenses of $51 million which included commissions, variable compensation and benefits, higher expenses for building, equipment and supplies of $9 million, higher expenses related to marketing and outside services of $8 million, higher travel related expenses of $7.3 million and higher equity based compensation of $4.6 million. Over the same period, the net impact of changes in foreign currency exchange rates decreased our operating expense by $5.8 million. The increase in personnel expenses is related to a net increase in our headcount of 634 employees during 2012.

We believe that our long-term growth and success depends on developing high quality software and hardware products on a timely basis. As such, we have made investments in research and development and our field sales force a priority. For the years ended December 31, 2013, 2012, and 2011, our sales and marketing expenses were $448 million, $431 million and $389 million, respectively, and research and development expenses were $235 million, $223 million and $199 million, respectively. The increase in sales and marketing expenses in 2013, was primarily driven by an increase in headcount of 139 from December 31, 2012, to December 31, 2013. As a result of our cost control efforts, sales and marketing headcount increased by only 18 from September 30, 2013, to December 31, 2013. The increase in research and development expenses for 2013 was primarily driven by an increase in headcount of 52 from December 31, 2012 to December 31, 2013. As a result of our cost control efforts, research and development headcount decreased by 25 from September 30, 2013, to December 31, 2013.

From a regional perspective, the increase in research and development expenses had a larger impact on the operating expenses of the Americas as the Americas absorbed $9 million of the overall $12 million increase in 2013 and $21 million of the overall $24 million increase in 2012.

Operating Income.  For the years ended December 31, 2013, 2012 and 2011, operating income was $99 million, $117 million and $113 million, respectively, a decrease of 16% in 2013, following an increase of 4% in 2012. As a percentage of net sales, operating income was 8%, 10% and 11%, respectively, over the three year period.  The decline in operating income in absolute dollars and as a percent of sales is attributable to the factors discussed in Net Sales, Gross Profit and Operating Expenses above. Our operating income in 2012 included the negative impact of the adjustment to the accrual related to our AWR acquisition of $6.8 million as a result of AWR’s performance exceeding our prior expectations and the positive impact of a favorable settlement from our GSA contract during the second quarter of 2012. The settlement of this matter was $1.3 million less than what we estimated in 2011.

Interest Income.Interest income was $679,000, $716,000 and $1.3 million for the years ended December 31, 2013, 2012 and 2011, respectively, a decrease of 5% in 2013, following a decrease of 46% in 2012. We continue to see low yields for high quality investment alternatives that comply with our corporate investment policy. We do not expect yields in these types of investments to increase significantly in 2014.   

Net Foreign Exchange Loss.Net foreign exchange loss was $(2.6) million, $(2.2) million, and $(2.8) million for the years ended December 31, 2013, 2012 and 2011, respectively. These results are attributable to movements in the foreign currency exchange rates between the U.S. dollar and foreign currencies in subsidiaries for which our functional currency is not the U.S. dollar. During 2013, there was mixed, and at times, significant volatility in the exchange rates between the U.S. dollar and most of the major currencies in the markets in which we do business which included significant strengthening of the U.S. dollar against the Japanese yen. During 2013, we also saw high volatility in the Euro and British pound against the U.S. dollar as well as a high level of volatility in the broader foreign currency exchange markets.We cannot predict the direction or degree of future volatility in these exchange rates. In the past, we have noted that significant volatility in foreign currency exchange rates in the markets in which we do business has had a significant impact on the revaluation of our foreign currency denominated firm commitments, on our ability to forecast our U.S. dollar equivalent revenues and expenses and on the effectiveness of our hedging programs. In the past, these dynamics have also adversely affected our revenue growth in international markets and may pose similar challenges in the future. We recognize the local currency as the functional currency in virtually all of our international subsidiaries.

We utilize foreign currency forward contracts to hedge our foreign denominated net foreign currency balance sheet positions to help protect against the change in value caused by a fluctuation in foreign currency exchange rates. We typically hedge up to 90% of our outstanding foreign denominated net receivable or payable positions and typically limit the duration of these foreign currency forward contracts to approximately 90 days. The gain or loss on these derivatives as well as the offsetting gain or loss on the hedged item attributable to the hedged risk is recognized in current earnings under the line item “Net foreign exchange loss”. Our hedging strategy increased our foreign exchange losses by $267,000 in 2013, increased our foreign exchange losses by $2.1 million in 2012, and reduced our foreign exchange losses by $959,000 in 2011.

Provision for Income Taxes.  For the years ended December 31, 2013, 2012 and 2011, our provision for income taxes reflected an effective tax rate of 17%, 22% and 15%, respectively. The factors that caused our effective tax rates to change year-over-year are detailed in the table below:

	Years ended

Other operational metrics  

We believe that the following additional unaudited operational metrics assist investors in assessing our operational performance relative to our others in our industry and to our historical results.  

Acquisition related deferred revenue and GSA accrual adjustment excluded from revenue. For the three month periods and years ended December 31, 2013 and 2012, the excluded acquisition related deferred revenue and the reduction of revenue resulting from our GSA accrual were as follows:

(In thousands)		Three Months Ended December 31,				Years Ended December 31,

Total	$	-	$	-	$	-	$	525

In June 2012, we entered into a Settlement Agreement with the General Services Administration (GSA) and paid approximately $11.8 million in settlement of overpayments under our previous agreement with GSA. In September 2011, we established an accrual of $13.1 million related to this matter. We cancelled our contract with GSA in May 2011.

Charges related to stock-based compensation, amortization of acquired intangibles and acquisition related transaction costs. For the three month periods and years ended December 31, 2013 and 2012, the gross charges related to stock-based compensation as a component of cost of sales, sales and marketing, research and development, and general and administrative expenses and the total charges were as follows:

Liquidity and Capital Resources  

Working Capital, Cash and Cash Equivalents and Short-term Investments.  Cash, cash equivalents and short-term investments increased by $58 million to $393 million at December 31, 2013 from $335 million at December 31, 2012. The following table presents our working capital, cash and cash equivalents and short-term investments:    

						Increase/
(In thousands)		December 31, 2013		December 31, 2012		(Decrease)
Working capital	$	603,240	$	522,744	$	80,496

Total cash, cash equivalents and short-term investments	$	393,412	$	335,162	$	58,250
(1) Included in working capital

During the year ended December 31, 2013, our working capital increased by $80 million. Overall, current assets increased by $61 million while current liabilities decreased by $20 million. The increase in our current assets was the result of a $58 million increase in cash, cash equivalents and short-term investments. The decrease in current liabilities was primarily driven by a decrease in accounts payable and accrued compensation of $13 million as well as a decrease in accrued expenses and taxes payable of $12 million. The decreases in these current liability accounts are consistent with the cost control measures we began implementing during the second quarter of 2013.

Accounts receivable decreased by $6.4 million to $181 million at December 31, 2013, from $187 million at December 31, 2012. Days sales outstanding increased to 57 days at December 31, 2013, compared to 55 days at December 31, 2012.

Inventory increased by $2.1 million to $172 million at December 31, 2013, from $170 million at December 31, 2012. As a result of this increase, inventory turns decreased to 1.8 at December 31, 2013 from 1.9 at December 31, 2012.

Prepaid expenses and other current assets increased $992,000 to $49 million December 31, 2013, from $48 million at December 31, 2012.

Our cash and cash equivalent balances are held in numerous financial institutions throughout the world, including substantial amounts held outside of the U.S., however, the majority of our cash and investments that are located outside of the U.S. are denominated in the U.S. dollar with the exception of $17 million U.S. dollar equivalent of German government sovereign debt and $16 million U.S. dollar equivalent of corporate bonds that are denominated in Euro. Our German government sovereign debt holdings have a maximum remaining maturity of 18 months and carry Aaa/AAA ratings. Our short-term investments do not include sovereign debt from any other countries in Europe. At December 31, 2013, we had $393 million in cash, cash equivalents and short-term investments. Approximately $69 million or 18% of these amounts were held in domestic accounts with various financial institutions and $324 million or 82% was held in accounts outside of the U.S. with various financial institutions. At December 31, 2013, we had cash and cash equivalents of $230 million of which $69 million or 30% was held in domestic accounts and $161 million or 70% was held in various accounts of our foreign subsidiaries. At December 31, 2013, we had short-term investments of $163 million which was all held in investment accounts of our foreign subsidiaries. Most of the amounts held outside of the U.S. could be repatriated to the U.S., but under current law, would be subject to U.S. federal income taxes, less applicable foreign tax credits. We have provided for the U.S. federal tax liability on these amounts for financial statement purposes, except for foreign earnings that are considered indefinitely reinvested outside of the U.S. Repatriation could result in substantial additional U.S. federal income tax payments in future years. We utilize a variety of tax planning and financing strategies with the objective of having our worldwide cash available in the locations in which it is needed.

Cash Provided by and (Used in) in the years ended December 31, 2013 and 2012. The following table summarizes the proceeds and (uses) of cash:  

(In thousands)		December 31,
		2013		2012

Cash and cash equivalents at beginning of year		161,996		142,608
Cash and cash equivalents at end of period	$	230,263	$	161,996

31  

For the years ended December 31, 2013 and 2012, cash provided by operating activities was $169 million and $133 million, respectively. Year over year, we had an increase in cash provided by operating assets and liabilities of $47 million offset by a decrease in net income of $10 million.

Investing activities used cash of $58 million during the year ended December 31, 2013, as the result of capital expenditures of $48 million and capitalization of internally developed software and other intangibles of $15 million, offset by the net sale of $10 million of short-term investments. Capital expenditures during year ended December 31, 2013 included payments related to additional land use rights and the finishing stages of the construction of our Malaysian manufacturing facility as well as leasehold improvements, computers, equipment and furniture and fixtures to support operations in our Malaysian manufacturing facility as well as other parts of our business. Investing activities used cash of $78 million during the year ended December 31, 2012, as the result of acquisitions of $25 million, net of cash received, as well as the purchase of property and equipment and other intangibles of $91 million, the capitalization of internally developed software of $12 million, offset by the net sale of $50 million of short-term investments.

Financing activities used cash of $43 million during the year ended December 31, 2013, which was the result of $70 million used to pay dividends to our stockholders, $15 million used to settle deferred payments related to previous acquisitions, offset by $39 million received from the issuance of our common stock from the exercise of employee stock options and from our employee stock purchase plan. Financing activities used cash of $35 million during the year ended December 31, 2012, which was the result of $68 million used to pay dividends to our stockholders offset by $31 million received from the issuance of our common stock from the exercise of stock options and under our employee stock purchase plan as well as a tax benefit of $2.2 million.

From time to time, our Board of Directors has authorized various programs to repurchase shares of our common stock depending on market conditions and other factors. We did not make any purchases under this program during the year ended December 31, 2013. At December 31, 2013, there were 3,932,245 shares remaining available for repurchase under this program. This repurchase program does not have an expiration date.  

During the year ended December 31, 2013, we received more in proceeds from the exercise of stock options compared to the year ended December 31, 2012. The timing and number of stock option exercises and the amount of cash proceeds we receive through those exercises are not within our control. Since 2005, it has been our practice to issue restricted stock units and not stock options to eligible employees which has reduced the number of stock options available for exercise in the future. Unlike the exercise of stock options, the issuance of shares upon vesting of restricted stock units does not result in any cash proceeds to us. There are outstanding options to purchase 287,000 shares remaining of which options for 218,000 shares have contractual expiration dates in 2014. These options have weighted average exercise prices of between $18.95 and $19.92 per share. As such, we will not generate as much cash from the exercise of stock options in 2014 as we did in 2013 and very little if any after 2014.  

Contractual Cash Obligations.    The following summarizes our contractual cash obligations as of December 31, 2013:

We have commitments under non-cancelable operating leases primarily for office facilities throughout the world. Certain leases require us to pay property taxes, insurance and routine maintenance, and include escalation clauses. As of December 31, 2013, we had non-cancelable operating lease obligations of approximately $67 million compared to $63 million at December 31, 2012. Rent expense under operating leases was $19 million, $17 million and $16 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Purchase obligations primarily represent purchase commitments for customized inventory and inventory components. As of December 31, 2013, we had non-cancelable purchase commitments with various suppliers of customized inventory and inventory components totaling approximately $11 million over the next twelve months. At December 31, 2012, we had non-cancelable purchase commitments with various suppliers of customized inventory and inventory components totaling approximately $7 million.

32  

At December 31, 2013, we had outstanding guarantees for payment of customs and foreign grants totaling approximately $5.2 million. At December 31, 2012, we had outstanding guarantees for payment of customs, foreign grants and potential customer disputes totaling approximately $5.0 million.

Loan Agreement. On May 9, 2013, we entered into a Loan Agreement (the “Loan Agreement”) with Wells Fargo Bank, National Association (the “Lender”). The Loan Agreement provides for a $50 million unsecured revolving line of credit with a scheduled maturity date of May 9, 2018 (the “Maturity Date”). Proceeds of loans made under the Loan Agreement may be used for working capital and other general corporate purposes. We may prepay the loans under the Loan Agreement in whole or in part at any time without premium or penalty. Certain of our existing and future material domestic subsidiaries are required to guaranty our obligations under the Loan Agreement. We may choose to borrow funds against this line of credit in future periods to have sufficient domestic cash to fund continued dividends to our stockholders, to fund potential acquisitions or other domestic general corporate purposes without the need to repatriate foreign earnings. As of December 31, 2013, we had not utilized any amount available under this line of credit and we were in compliance with all applicable covenants in the Loan Agreement.

Off-Balance Sheet Arrangements.We do not have any debt or off-balance sheet debt. At December 31, 2013, we did not have any relationships with any unconsolidated entities or financial partnerships, such as entities often referred to as structured finance entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we were engaged in such relationships.  

Prospective Capital Needs.We believe that our existing cash, cash equivalents and short-term investments, together with cash generated from operations as well as from the exercise of employee stock options and the purchase of common stock through our employee stock purchase plan and available borrowings under our loan agreement will be sufficient to cover our working capital needs, capital expenditures, investment requirements, commitments, payment of dividends to our stockholders and repurchases of our common stock for at least the next 12 months, although the use of certain of our funds for domestic purposes may require us to repatriate foreign earnings which would be subject to the U.S. federal statutory tax rate of 35%. We may also seek to pursue additional financing or to raise additional funds by selling equity or debt to the public or in private transactions. If we elect to raise additional funds, we may not be able to obtain such funds on a timely basis on acceptable terms, if at all. If we raise additional funds by issuing additional equity or convertible debt securities, the ownership percentages of our existing stockholders would be reduced. In addition, the equity or debt securities that we issue may have rights, preferences or privileges senior to those of our common stock. We may also choose to repatriate foreign earnings which would be subject to the U.S. federal statutory tax rate of 35% and therefore, would likely have a material adverse effect on our effective tax rate and on our net income and earnings per share. We could also choose to reduce certain expenditures or payments of dividends or suspend our program to repurchase shares of our common stock. Historically, we have not had to rely on debt, public or private, to fund our operating, financing or investing activities.

Although we believe that we have sufficient capital to fund our operating activities for at least the next 12 months, our future capital requirements may vary materially from those now planned. We anticipate that the amount of capital we will need in the future will depend on many factors, including:  

· payment of dividends to our stockholders;

· difficulties and the high tax costs associated with the repatriation of earnings;

· required levels of research and development and other operating costs;

· our business, product, capital expenditure and research and development plans, and product and technology roadmaps; 

· the overall levels of sales of our products and gross profit margins;

· the levels of inventory and accounts receivable that we maintain;

· general economic and political uncertainty and specific conditions in the markets we address, including any volatility in the industrial economy in the various geographic regions in which we do business;

· the inability of certain of our customers who depend on credit to have access to their traditional sources of credit to finance the purchase of products from us, which may lead them to reduce their level of purchases or to seek credit or other accommodations from us;

· acquisitions of other businesses, assets, products or technologies; 

· capital improvements for new and existing facilities; 

· repurchases of our common stock; 

· our relationships with suppliers and customers; and 

· the level of exercises of stock options and stock purchases under our employee stock purchase plan.  

Recently Issued Accounting Pronouncements  

See Note 1 – Operations and Summary of Significant Accounting Policies for discussion regarding recently issued accounting pronouncements.

Critical Accounting Policies

The preparation of our financial statements in conformity with generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Although these estimates are based on management's best knowledge of current events and actions that may impact the company in the future, actual results may be materially different from the estimates.

Our critical accounting policies are as follows:

· Revenue recognition

We sell test and measurement solutions that include hardware, software licenses, and related services. Our sales are generally made under standard sales arrangements with payment terms ranging from net 30 days in the U.S. to net 30 days and up to net 120 days in some international markets. We offer rights of return and standard warranties for product defects related to our products. The rights of return are generally for a period of up to 30 days after the delivery date. Our standard warranties cover periods ranging from 90 days to three years. Our standard sales arrangements do not require product acceptance from the customer.

In recent years, we have made a concentrated effort to increase our revenue through the pursuit of orders with a value greater than $1.0 million. These orders often include contract terms that vary substantially from our standard terms of sale including product acceptance requirements and product performance evaluations which create uncertainty with respect to the timing of our ability to recognize revenue from such orders. These orders may also include most-favored customer pricing, significant discounts, extended payment terms and volume rebates, all of which also may create uncertainty with respect to the amount and timing of revenue recognized from such orders.

Sales of application software licenses include post-contract support services. Other services include customer training, customer support, and extended warranties.

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, and collectability is reasonably assured. Delivery is considered to have occurred when title and risk of loss have transferred to the customer. For most of our hardware and software sales, title and risk of loss transfer upon delivery. For services, we recognize revenue when the service is provided, except for extended warranties for which revenue is recognized ratably over the warranty period.

We enter into certain arrangements in which we deliver multiple products and/or services. These arrangements may include hardware, software, and services. We separate consideration in multiple-deliverable arrangements by allocating to all deliverables using the relative selling price method at the inception of an arrangement. Revenue allocated to each element is then recognized when the basic revenue recognition criteria for that element have been met. The relative selling price method allocates any discount in the arrangement proportionally to each deliverable on the basis of each deliverable’s selling price. The selling price used for each deliverable will be based on vendor-specific objective evidence (“VSOE”) if available, third–party evidence if VSOE is not available, or estimated selling price if neither VSOE nor third-party evidence is available.

Software revenue recognition rules are applied to software sold on a stand-alone basis, and to software sold as part of a multiple element arrangement with hardware where the software is not required to deliver the tangible product's essential functionality. Under these rules, when VSOE of fair value is not available for a delivered element but is available for the undelivered element of a multiple element arrangement, sales revenue is recognized on the date the product is shipped, using the residual method, with the portion deferred that is related to undelivered elements. Undelivered elements related to software are generally restricted to post contract support and training and education. The amount of revenue allocated to these undelivered elements is based on the VSOE of fair value for those undelivered elements. Deferred revenue due to undelivered elements is recognized ratably over the service period or when the service is completed. When VSOE of fair value is not available for the undelivered element of a multiple element arrangement, sales revenue for the entire sales contract value is generally recognized ratably over the service period of the undelivered element, generally 12 months or when the service is completed in accordance with the subscription method.

The application of revenue recognition standards requires judgment, including whether a software arrangement includes multiple elements, and if so, whether VSOE of fair value exists for those elements. Changes to the elements in a software arrangement, the ability to identify VSOE for those elements, the fair value of the respective elements, and changes to a product’s estimated life cycle could materially impact the amount of our earned and unearned revenue. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products.

34  

· Estimating allowances for sales returns

The preparation of financial statements requires that we make estimates and assumptions of potential future product returns related to current period product revenue. We analyze historical returns, current economic trends, and changes in customer demand and acceptance of our products when evaluating the adequacy of our sales returns allowance. Significant judgments and estimates must be made and used in connection with establishing the sales returns allowance in any accounting period. A provision for estimated sales returns is made by reducing recorded revenue by the amount of the allowance. Accounts receivable is reported net of the allowance for sales returns. Our allowance for sales returns was $1.6 million and $2.1 million at December 31, 2013 and 2012, respectively. Material differences may result in the amount and timing of our revenue for any period if we made different judgments or utilized different estimates or if our actual results varied materially from our estimates.

· Estimating allowances, specifically the allowance for doubtful accounts and the adjustment for excess and obsolete inventories

In addition to estimating an allowance for sales returns, we must also make estimates about the uncollectability of our accounts receivables. We specifically analyze accounts receivable and analyze historical bad debts, customer concentrations, customer credit-worthiness and current economic trends when evaluating the adequacy of our allowance for doubtful accounts. Our allowance for doubtful accounts was $2.8 million and $2.8 million at December 31, 2013 and 2012, respectively. We also write down our inventory for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and estimated market value based on assumptions of future demand and market conditions. Our allowance for excess and obsolete inventories was $5.5 million and $3.8 million at December 31, 2013 and 2012, respectively. Significant judgments and estimates must be made and used in connection with establishing these allowances. Material differences may result in the amount and timing of our bad debt and inventory obsolescence if we made different judgments or utilized different estimates or if actual results varied materially from our estimates.

· Accounting for costs of computer software

We capitalize costs related to the development and acquisition of certain software products. Capitalization of costs begins when technological feasibility has been established and ends when the product is available for general release to customers. Technological feasibility for our products is established when the product is available for beta release. Judgment is required in determining when technological feasibility of a product is established. Amortization is computed on an individual product basis for those products available for market and has been recognized based on the product’s estimated economic life, generally three years. At each balance sheet date, the unamortized costs are reviewed by management and reduced to net realized value when necessary. As of December 31, 2013 and 2012, unamortized capitalized software development costs were $23 million and $22 million, respectively.

· Valuation of long-lived and intangible assets

We assess the impairment of identifiable intangibles, long-lived assets and related goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In accordance with FASB ASC 350, Intangibles – Goodwill and Other (FASB ASC 350), goodwill is tested for impairment on an annual basis, and between annual tests if indicators of potential impairment exist, using a fair-value-based approach based on the market capitalization of the reporting unit. Our annual impairment test was performed as of February 28, 2013. No impairment of goodwill and long-lived and intangible assets was identified during 2013 and 2012. Goodwill is deductible for tax purposes in certain jurisdictions. We have defined our operating segment based on geographic regions. We sell our products in four geographic regions. Our sales to these regions share similar economic characteristics, similar product mix, similar customers, and similar distribution methods. Accordingly, we have elected to aggregate these four geographic regions into a single operating segment. As we have one reporting segment, we allocate goodwill to one reporting unit for goodwill impairment testing. Factors considered important which could trigger an impairment review include the following:

· significant underperformance relative to expected historical or projected future operating results;

· significant changes in the manner of our use of the acquired assets or the strategy for our overall business;

· significant negative industry or economic trends; and,

· our market capitalization relative to net book value.

When it is determined that the carrying value of intangibles, long-lived assets and related goodwill may not be recoverable based upon the existence of one or more of the above indicators of impairment, the measurement of any impairment is determined and the carrying value is reduced as appropriate. As of December 31, 2013 and 2012, we had goodwill of approximately $147 million in each year.

35  

· Accounting for income taxes

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position or our results of operations. In estimating future tax consequences, all expected future events are considered other than enactments of changes in tax laws or rates. We account for uncertainty in income taxes recognized in our financial statements using prescribed recognition thresholds and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on our tax returns. Our continuing policy is to recognize interest and penalties related to income tax matters in income tax expense.

The tax position of our Hungarian operations continues to benefit from assets created by the restructuring of our operations in Hungary in 2003. In addition, our research and development activities in Hungary continue to benefit from a tax law in Hungary that provides for an enhanced deduction for qualified research and development expenses. Partial release of the valuation allowance on assets from the restructuring and the enhanced tax deduction for research expenses resulted in income tax benefits of $12 million and $17 million for the years ended December 31, 2013 and 2012, respectively.

Our earnings in Hungary are subject to a statutory tax rate of 19%. The difference between this rate and the statutory U.S. rate of 35% resulted in income tax benefits of $8 million and $12 million for the years ended December 31, 2013 and 2012, respectively. No country other than Hungary had a significant impact on our effective tax rate. We have not entered into any advanced pricing or other agreements with the Internal Revenue Service with regard to any foreign jurisdictions.

For additional discussion about our income taxes including components of income before income taxes, our provision for income taxes charged to operations, components of our deferred tax assets and liabilities, a reconciliation of income taxes at the U.S. federal statutory rate of 35% to our effective tax rate and other tax matters, see Note 9 – Income taxes of Notes to Consolidated Financial Statements.

Loss contingencies

We accrue for probable losses from contingencies including legal defense costs, on an undiscounted basis, when such costs are considered probable of being incurred and are reasonably estimable. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary. Disclosure of a contingency is required if there is at least a reasonable possibility that a loss has been incurred. In determining whether a loss should be accrued we evaluate, among other factors, the degree of probability of an unfavorable outcome and our ability to make a reasonable estimate of the amount of loss. Changes in these factors could materially impact our financial position or our results of operation.

ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Financial Risk Management  

Our international sales are subject to inherent risks, including fluctuations in local economies; fluctuations in foreign currencies relative to the U.S. dollar; difficulties in staffing and managing foreign operations; greater difficulty in accounts receivable collection; costs and risks of localizing products for foreign countries; unexpected changes in regulatory requirements, tariffs and other trade barriers; difficulties and costs in the repatriation of earnings and burdens of complying with a wide variety of foreign laws.  

The vast majority of our sales outside of North America are denominated in local currencies, and accordingly, the U.S. dollar equivalent of these sales is affected by changes in the foreign currency exchange rates. The change in exchange rates had the effect decreasing our consolidated sales by $7.3 million in the year ended December 31, 2013, and decreasing our consolidated sales by $20 million in the year ended December 31, 2012. Since most of our international operating expenses are also incurred in local currencies, the change in exchange rates had the effect of decreasing our consolidated operating expenses by $2.2 million in the year ended December 31, 2013, and decreasing our consolidated operating expenses by $5.8 million in the year ended December 31, 2012.  

During 2013, there was mixed, and at times, significant volatility in the exchange rates between the U.S. dollar and most of the major currencies in the markets in which we do business which included significant strengthening of the U.S. dollar against the Japanese yen. We cannot predict to what degree or how long this volatility in the foreign currency exchange markets will continue. In the past, we have noted that significant volatility in foreign currency exchange rates in the markets in which we do business has had a significant impact on the revaluation of our foreign currency denominated firm commitments, on our ability to forecast our U.S. dollar equivalent revenues and expenses and on the effectiveness of our hedging programs. In the past, these dynamics have also adversely affected our revenue growth in international markets and may pose similar challenges in the future. We recognize the local currency as the functional currency in virtually all of our international subsidiaries.

If the local currencies in which we sell our products strengthen against the U.S. dollar, we may need to lower our prices in the local currency to remain competitive in our international markets which could have a material adverse effect on our gross and net profit margins. If the local currencies in which we sell our products weaken against the U.S. dollar and if the local sales prices cannot be raised due to competitive pressures, we will experience a deterioration of our gross and net profit margins. To help protect against the change in the value caused by a fluctuation in foreign currency exchange rates of forecasted foreign currency cash flows resulting from international sales and expenses over the next one to two years, we have a foreign currency cash flow hedging program. We hedge portions of our forecasted revenue, cost of sales and operating expenses denominated in foreign currencies with foreign currency forward contracts. For forward contracts, when the dollar strengthens significantly against the foreign currencies, the change in the present value of future foreign currency cash flows may be offset by the change in the fair value of the forward contracts designated as hedges. For purchased option contracts, when the dollar strengthens significantly against the foreign currencies, the change in the present value of future foreign currency cash flows may be offset by the change in the fair value of the option contracts designated as hedges, net of the premium paid. Our foreign currency purchased option contracts are purchased “at-the-money” or “out-of-the-money.” We purchase foreign currency forward and option contracts for up to 100% of our forecasted exposures in selected currencies (primarily in Euro, Japanese yen, and Hungarian forint) and limit the duration of these contracts to 40 months or less. As a result, our hedging activities only partially address our risks from foreign currency transactions, and there can be no assurance that this strategy will be successful. We do not invest in contracts for speculative purposes.   

During 2013, our hedges had the effect of increasing our consolidated sales by $3.2 million, decreasing our cost of sales by $118,000, and decreasing our operating expenses by $87,000. During 2012, our hedges had the effect of increasing our consolidated sales by $2.9 million, decreasing our cost of sales by $402,000, and decreasing our operating expenses by $259,000. (See Note 4 - Derivative instruments and hedging activities of Notes to Consolidated Financial Statements for further discussion regarding our cash flow hedging program and its related impacted on our consolidated sales, cost of sales and operating expenses for the years ended December 31, 2013 and 2012).  

Inventory Management  

The markets for our products dictate that many of our products be shipped very quickly after an order is received. As a result, we are required to maintain significant inventories. Therefore, inventory obsolescence is a risk for us due to frequent engineering changes, shifting customer demand, the emergence of new industry standards and rapid technological advances including the introduction by us or our competitors of products embodying new technology. However, our risk of obsolescence may be mitigated as many of our products have interchangeable parts and many have long lives. While we adjust for excess and obsolete inventories and we monitor the valuation of our inventories, there can be no assurance that our valuation adjustments will be sufficient.  

37  

In recent years, we have made a concentrated effort to increase our revenue through the pursuit of orders with a value greater than $1.0 million. Fulfillment of these contracts can severely challenge our supply chain capabilities at the component acquisition, assembly and delivery stages. These contracts can also require us to develop specific product mitigation plans for product delivery constraints caused by unexpected or catastrophic situations to help assure timely production recovery and to comply with critical delivery commitments where severe contractual liabilities can be imposed on us if we fail to provide the quantity of products at the required delivery times. In order to help mitigate the risks associated with these contractual requirements, we may choose to build inventory levels for certain parts or systems. Because our contracts with such customers may allow the customer to cancel or delay orders without liability, such actions expose our business to increased risk of inventory obsolescence.

Market Risk  

We are exposed to a variety of risks, including foreign currency fluctuations and changes in the market value of our investments. In the normal course of business, we employ established policies and procedures to manage our exposure to fluctuations in foreign currency values and changes in the market value of our investments.  

Cash, Cash Equivalents and Short-Term Investments  

At December 31, 2013, we had $393 million in cash, cash equivalents and short-term investments of which $69 million or 18% is held in domestic accounts and $324 million or 82% is held in international accounts. We maintain cash and cash equivalents and short-term investments with various financial institutions located in many countries throughout the world. At December 31, 2013, we had cash and cash equivalents of $230 million of which $142 million or 62% was held in cash in various operating accounts throughout the world and $88 million or 38% was held in money market accounts. The most significant of our operating accounts was our domestic operating account which held approximately $15 million or 6% of our total cash and cash equivalents at a bank that carried A+/A2/AA- ratings. At December 31, 2013, we had short-term investments of $163 million, all of which was held in investment accounts of our foreign subsidiaries. Our short-term investments include $17 million U.S. dollar equivalent of German government sovereign debt and $16 million U.S. dollar equivalent of corporate bonds that are denominated in Euro. Our German government sovereign debt holdings have a maximum remaining maturity of 18 months and carry Aaa/AAA ratings. Our short-term investments do not include sovereign debt from any other countries in Europe.  

We value our available-for-sale short term investments based on pricing from third party pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. We classify all of our fixed income available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of our financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. We believe these sources reflect the credit risk associated with each of our available for sale short term investments.

The goal of our investment policy is to manage our investment portfolio to preserve principal and liquidity while maximizing the return on our investment portfolio through the full investment of available funds. We place our cash investments in instruments that meet credit quality standards, as specified in our corporate investment policy guidelines. These guidelines also limit the amount of credit exposure to any one issue, issuer or type of instrument. Our cash equivalents and short-term investments carried ratings from the major credit rating agencies that were in accordance with our corporate investment policy. Our investment policy allows investments in the following: government and federal agency obligations, repurchase agreements (“Repos”), certificates of deposit and time deposits, corporate obligations, medium term notes and deposit notes, commercial paper including asset-backed commercial paper (“ABCP”), puttable bonds, general obligation and revenue bonds, money market funds, taxable commercial paper, corporate notes/bonds, municipal notes, municipal obligations, variable rate demand notes and tax exempt commercial paper. All such instruments must carry minimum ratings of A1/P1/F1, MIG1/VMIG1/SP1 and A2/A/A, as applicable, all of which are considered “investment grade”. Our investment policy for marketable securities requires that all securities mature in three years or less, with a weighted average maturity of no longer than 18 months with at least 10% maturing in 90 days or less.  

We account for our investments in debt and equity instruments under FASB ASC 320 Investments – Debt and Equity Securities (FASB ASC 320). Our investments are classified as available-for-sale and accordingly are reported at fair value, with unrealized gains and losses reported as other comprehensive income, a component of stockholders’ equity. Unrealized losses are charged against income when a decline in fair value is determined to be other-than-temporary. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The fair value of our short-term investments at December 31, 2013 and 2012, was $163 million and $173 million, respectively. This decrease was due to the net sale of $10 million of short-term investments.   

We follow the guidance provided by FASB ASC 320 to assess whether our investments with unrealized loss positions are other than temporarily impaired. Realized gains and losses and declines in value judged to be other-than-temporary are determined based on the specific identification method and are reported in other income (expense), net, in our Consolidated Statements of Income. There were not any other-than-temporary impairments recognized in other expense during the years ended December 31, 2013.  

38  

Interest Rate Risk  

Investments in both fixed rate and floating rate instruments carry a degree of interest rate risk. Fixed rate securities may have their market value adversely impacted due to an increase in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due to these factors, our future investment income may fall short of expectations due to changes in interest rates or if the decline in the fair value of our publicly traded debt investments is judged to be other-than-temporary. We may suffer losses in principal if we are forced to sell securities that have declined in market value due to changes in interest rates. However, because any debt securities we hold are classified as available-for-sale, no gains or losses are realized in our income statement due to changes in interest rates unless such securities are sold prior to maturity or unless declines in value are determined to be other-than-temporary. These securities are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of stockholders’ equity, net of tax.  

In a declining interest rate environment, as short-term investments mature, reinvestment occurs at less favorable market rates. Given the short-term nature of certain of our investments, the current interest rate environment of low rates has negatively impacted our investment income.  

In order to assess the interest rate risk associated with our investment portfolio, we performed a sensitivity analysis to determine the impact a change in interest rates would have on the value of our investment portfolio assuming a 100 basis point parallel shift in the yield curve. Based on our investment positions as of December 31, 2013, a 100 basis point increase or decrease in interest rates across all maturities would result in approximately a $796,000 increase or decrease in the fair market value of our portfolio. As of December 31, 2012, a similar 100 basis point increase or decrease in interest rates across all maturities would result in approximately  a $844,000 increase or decrease in the fair market value of our portfolio. Such losses would only be realized if we sold the investments prior to maturity or if there is an other-than-temporary impairment. Actual future gains and losses associated with our investments may differ from the sensitivity analyses performed as of December 31, 2013, due to the inherent limitations associated with predicting the changes in the timing and level of interest rates and our actual exposures and positions.  

We continue to monitor the stability of the financial markets, particularly those in the European region and have taken steps to limit our direct and indirect exposure to these markets; however, we can give no assurance that we will not be negatively impacted by any adverse outcomes in those markets. We also continue to weigh the benefit of the higher yields associated with longer maturities against the interest rate risk and credit rating risk, also associated with these longer maturities when making these decisions. We cannot predict when or if interest rates and investment yields will rise. If yields continue to stay at these low levels, our investment income will continue to be negatively impacted.  

Exchange Rate Risk  

Our objective in managing our exposure to foreign currency exchange rate fluctuations is to reduce the impact of adverse fluctuations in such exchange rates on our earnings and cash flow. Accordingly, we utilize purchased foreign currency option and forward contracts to hedge our exposure on anticipated transactions and firm commitments. The principal currencies hedged are the Euro, Japanese yen, Malaysian ringgit, British pound and Hungarian forint. We monitor our foreign exchange exposures regularly to help ensure the overall effectiveness of our foreign currency hedge positions. There can be no assurance that our foreign currency hedging activities will substantially offset the impact of fluctuations in currency exchanges rates on our results of operations and financial position. Based on the foreign exchange instruments outstanding at December 31, 2013 and 2012, an adverse change (defined as 20% in the Asian currencies and 10% in all other currencies) in exchange rates would result in a decline in the aggregate settlement value of all of our instruments outstanding of approximately $15 million and $22 million, respectively. However, as we utilize foreign currency instruments for hedging anticipated and firmly committed transactions, we believe that a loss in settlement value for those instruments will be substantially offset by increases in the value of the underlying exposure. (See Note 4 - Derivative instruments and hedging activities of Notes to Consolidated Financial Statements for a further description of our derivative instruments and hedging activities).

ITEM 9A.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures  

As of the end of the period covered by this Annual Report on Form 10-K, our Chief Executive Officer, Dr. James Truchard, and our Executive Vice President, Chief Operating Officer and Chief Financial Officer, Alex Davern, based on their evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended), required by paragraph (b) of Rule 13a – 15 or Rule 15d – 15, have concluded that our disclosure controls and procedures were effective at the reasonable assurance level, to ensure the timely collection, evaluation and disclosure of information relating to us that would potentially be subject to disclosure under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder, and that such information is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. These disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures include components of our internal control over financial reporting. Our assessment of the effectiveness of our internal control over financial reporting is expressed at the level of reasonable assurance because a control system, no matter how well designed and operated, can provide only reasonable, but not absolute assurance that the control system’s objectives will be met.

Management Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements. We continue to enhance our internal control over financial reporting in key functional areas with the goal of monitoring our operations at the level of documentation, segregation of duties, and systems security necessary, as well as transactional control procedures required under Auditing Standard No. 5 issued by the Public Company Accounting Oversight Board. We discuss and disclose these matters to the audit committee of our board of directors and to our auditors.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2013, which was the end of our fiscal year. Management based its assessment on criteria established in Internal Control – Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management’s assessment included evaluation of such elements as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment. This assessment is supported by testing and monitoring performed by our finance organization and our internal audit department.

Based on this assessment, management has concluded that our internal control over financial reporting was effective as of the end of the fiscal year to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles. We reviewed the results of management’s assessment with the Audit Committee of our Board of Directors.

Our independent registered public accounting firm, Ernst & Young LLP, audited our consolidated financial statements, and independently assessed the effectiveness of our internal control over financial reporting. Ernst & Young LLP has issued their report, which is included in Part II, Item 8 of this Form 10-K.

Changes in Internal Control over Financial Reporting

During the three months ended December 31, 2013, there was no change in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or Rule 15d-15 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B.OTHER INFORMATION

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of National Instruments Corporation:

We have audited the accompanying consolidated balance sheets of National Instruments Corporation as of December 31, 2013 and 2012, and the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of National Instruments Corporation at December 31, 2013 and 2012, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), National Instruments Corporation’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) and our report dated February 20, 2014 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm on Internal Control over Financial Reporting

The Board of Directors and Stockholders of National Instruments Corporation:

We have audited National Instruments Corporation’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). National Instruments Corporation’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, National Instruments Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of National Instruments Corporation as of December 31, 2013 and 2012, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2013 and our report dated February 20, 2014 expressed an unqualified opinion thereon.

NATIONAL INSTRUMENTS CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Operations and summary of significant accounting policies

National Instruments Corporation is a Delaware corporation. We provide flexible application software and modular, multifunction hardware that users combine with industry-standard computers, networks and third party devices to create measurement, automation and embedded systems, which we also refer to as “virtual instruments.” Our approach gives customers the ability to quickly and cost-effectively design, prototype and deploy unique custom-defined solutions for their design, control and test application needs. We offer hundreds of products used to create virtual instrumentation systems for general, commercial, industrial and scientific applications. Our products may be used in different environments, and consequently, specific application of our products is determined by the customer and generally is not known to us. We approach all markets with essentially the same products, which are used in a variety of applications from research and development to production testing, monitoring and industrial control. The following industries and applications are served by us worldwide: advanced research, automotive, commercial aerospace, computers and electronics, continuous process manufacturing, education, government/defense, medical research/pharmaceutical, power/energy, semiconductors, automated test equipment, telecommunications and others. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America.

Principles of consolidation

The Consolidated Financial Statements include the accounts of National Instruments Corporation and its subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Use of estimates

The preparation of our financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Although these estimates are based on management's best knowledge of current events and actions that may impact the company in the future, actual results may be materially different from the estimates.

Cash and cash equivalents

Cash and cash equivalents include cash and highly liquid investments with maturities of three months or less at the date of acquisition.

Short-Term Investments

We value our available-for-sale short term investments based on pricing from third party pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. We classify all of our fixed income available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of our financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. We believe these sources reflect the credit risk associated with each of our available for sale short term investments. Short-term investments available-for-sale consists of debt securities issued by states of the U.S. and political subdivisions of the U.S., corporate debt securities and debt securities issued by U.S. government corporations and agencies as well as debt securities issued by foreign governments. All short-term investments available-for-sale have contractual maturities of less than 35 months.

Our investments are classified as available-for-sale and accordingly are reported at fair value, with unrealized gains and losses reported as other comprehensive income, a component of stockholders’ equity. Unrealized losses are charged against income when a decline in fair value is determined to be other than temporary. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The fair value of our short-term investments in debt securities at December 31, 2013 and December 31, 2012 was $163 million and $173 million, respectively. The decrease was due to the net sale of $10 million of short-term investments. We have $17 million U.S. dollar equivalent of German government sovereign debt and $16 million U.S. dollar equivalent of corporate bonds that are denominated in Euro at December 31, 2013. Our German government sovereign debt holdings have a maximum remaining maturity of 18 months and carry Aaa/AAA ratings.

We follow the guidance provided by FASB ASC 320 to assess whether our investments with unrealized loss positions are other than temporarily impaired. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in other income (expense), net, in our Consolidated Statements of Income. We did not identify or record any other-than-temporary impairments during 2013, 2012 and 2011.

F-9

Accounts Receivable, net

Accounts receivable are recorded net of allowances for sales returns of $1.6 million and $2.1 million at December 31, 2013 and 2012, respectively, and net of allowances for doubtful accounts of $2.8 million and $2.8 million at December 31, 2013 and 2012, respectively. A provision for estimated sales returns is made by reducing recorded revenue based on historical experience. We analyze historical returns, current economic trends and changes in customer demand of our products when evaluating the adequacy of our sales returns allowance. Our allowance for doubtful accounts is based on historical experience. We analyze historical bad debts, customer concentrations, customer creditworthiness and current economic trends when evaluating the adequacy of our allowance for doubtful accounts.

2013	Allowance for doubtful accounts and sales returns	$	4,870	$	(43)	$	396	$	4,431

Inventories, net

Inventories are stated at the lower-of-cost or market. Cost is determined using standard costs, which approximate the first-in first-out (“FIFO”) method. Cost includes the acquisition cost of purchased components, parts and subassemblies, in-bound freight costs, labor and overhead. Market is replacement cost with respect to raw materials and is net realizable value with respect to work in process and finished goods.

Inventory is shown net of adjustment for excess and obsolete inventories of $5.5 million, $3.8 million and $4.2 million at December 31, 2013, 2012 and 2011, respectively.

Year	Description		Balance at Beginning of Period		Provisions		Write-Offs		Balance at End of Period

2013	Adjustment for excess and obsolete inventories	$	3,844	$	3,488	$	1,873	$	5,459

Property and equipment, net

Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from twenty to forty years for buildings, three to seven years for purchased internal use software and for equipment which are each included in furniture and equipment. Leasehold improvements are depreciated over the shorter of the life of the lease or the asset.

Intangible assets, net

We capitalize costs related to the development and acquisition of certain software products. Capitalization of costs begins when technological feasibility has been established and ends when the product is available for general release to customers. Technological feasibility for our products is established when the product is available for beta release. Amortization is computed on an individual product basis for those products available for market and is recognized based on the product’s estimated economic life, generally three years.

We use the services of outside counsel to search for, document, and apply for patents. Those costs, along with any filing or application fees, are capitalized. Costs related to patents which are abandoned are written off. Once a patent is granted, the patent costs are amortized ratably over the legal life of the patent, generally ten to seventeen years.

At each balance sheet date, the unamortized costs for all intangible assets are reviewed by management and reduced to net realizable value when necessary.

Goodwill

The excess purchase price over the fair value of net assets acquired is recorded as goodwill. As we have one operating segment, we allocate goodwill to one reporting unit for goodwill impairment testing. Goodwill is tested for impairment on an annual basis, and between annual tests if indicators of potential impairment exist, using a fair-value-based approach based on the market capitalization of the reporting unit. Our annual impairment test was performed as of February 28, 2013. No impairment of goodwill was identified during 2013 and 2012. Goodwill is deductible for tax purposes in certain jurisdictions.

F-10

Concentrations of credit risk

We maintain cash and cash equivalents with various financial institutions located in many countries throughout the world. At December 31, 2013, $142 million or 62% of our cash and cash equivalents was held in cash in various operating accounts with financial institutions throughout the world, and $88 million or 38% was held in money market accounts. The most significant of our operating accounts was our domestic Wells Fargo operating account which held approximately $15 million or 6% of our total cash and cash equivalents at a bank that carried A+/A2/AA- ratings at December 31, 2013. From a geographic standpoint, approximately $69 million or 30% of our cash was held in various domestic accounts with financial institutions and $161 million or 70% was held in various accounts outside of the U.S. with financial institutions. At December 31, 2013, our short-term investments consist of $17 million or 11% of foreign government bonds, $72 million or 44% of U.S. treasuries and agencies, $71 million or 43% of corporate notes, and $3 million or 2% in time deposits.

The goal of our investment policy is to manage our investment portfolio to preserve principal and liquidity while maximizing the return on our investment portfolio through the full investment of available funds. We place our cash investments in instruments that meet credit quality standards, as specified in our corporate investment policy guidelines. These guidelines also limit the amount of credit exposure to any one issue, issuer or type of instrument. Our cash equivalents and short-term investments carried ratings from the major credit rating agencies that were in accordance with our corporate investment policy. Our investment policy allows investments in the following: government and federal agency obligations, repurchase agreements (“Repos”), certificates of deposit and time deposits, corporate obligations, medium term notes and deposit notes, commercial paper including asset-backed commercial paper (“ABCP”), puttable bonds, general obligation and revenue bonds, money market funds, taxable commercial paper, corporate notes/bonds, municipal notes, municipal obligations, variable rate demand notes and tax exempt commercial paper. All such instruments must carry minimum ratings of A1/P1/F1, MIG1/VMIG1/SP1 and A2/A/A, as applicable, all of which are considered “investment grade”. Our investment policy for marketable securities requires that all securities mature in three years or less, with a weighted average maturity of no longer than 18 months with at least 10% maturing in 90 days or less. (See Note 2 – Cash, cash equivalents, short-term and long-term investments in Notes to Consolidated Financial Statements for further discussion and analysis of our investments).

Concentration of credit risk with respect to trade accounts receivable is limited due to our large number of customers and their dispersion across many countries and industries. The amount of sales to any individual customer did not exceed 3%, 7%, or 4% of revenue for the years ended December 31, 2013, 2012, or 2011, respectively. The largest trade account receivable from any individual customer at December 31, 2013 was approximately $6.1 million.

Key supplier risk

Our manufacturing processes use large volumes of high-quality components and subassemblies supplied by outside sources. Several of these components are available through sole or limited sources. Supply shortages or quality problems in connection with some of these key components could require us to procure components from replacement suppliers, which would cause significant delays in fulfillment of orders and likely result in additional costs. In order to manage this risk, we maintain safety stock of some of these single sourced components and subassemblies and perform regular assessments of suppliers performance, grading key suppliers in critical areas such as quality and “on-time” delivery.

Revenue recognition

We sell test and measurement solutions that include hardware, software licenses, and related services. Our sales are generally made under standard sales arrangements with payment terms ranging from net 30 days in the United States to net 30 days and up to net 120 days in some international markets. We offer rights of return and standard warranties for product defects related to our products. The rights of return are generally for a period of up to 30 days after the delivery date. Our standard warranties cover periods ranging from 90 days to three years. Our standard sales arrangements do not require product acceptance from the customer.

In recent years, we have made a concentrated effort to increase our revenue through the pursuit of orders with a value greater than $1.0 million. These orders often include contract terms that vary substantially from our standard terms of sale including product acceptance requirements and product performance evaluations which create uncertainty with respect to the timing of our ability to recognize revenue from such orders. These orders may also include most-favored customer pricing, significant discounts, extended payment terms and volume rebates, all of which may create uncertainty with respect to the amount and timing of revenue recognized from such orders.

Sales of application software licenses include post-contract support services. Other services include customer training, customer support, and extended warranties.

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, and collectability is reasonably assured. Delivery is considered to have occurred when title and risk of loss have transferred to the customer. For most of our hardware and software sales, title and risk of loss transfer upon delivery. For services we recognize revenue when the service is provided, except for extended warranties for which revenue is recognized ratably over the warranty period.

F-11

We enter into certain arrangements in which we deliver multiple products and/or services. These arrangements may include hardware, software, and services. We separate consideration in multiple-deliverable arrangements by allocating to all deliverables using the relative selling price method at the inception of an arrangement.  Revenue allocated to each element is then recognized when the basic revenue recognition criteria for that element have been met. The relative selling price method allocates any discount in the arrangement proportionally to each deliverable on the basis of each deliverable’s selling price. The selling price used for each deliverable will be based on vendor-specific objective evidence (“VSOE”) if available, third–party evidence if VSOE is not available, or estimated selling price if neither VSOE nor third-party evidence is available.

Software revenue recognition rules are applied to software sold on a stand-alone basis, and to software sold as part of a multiple element arrangement with hardware where the software is not required to deliver the tangible product's essential functionality. Under these rules, when VSOE of fair value is not available for a delivered element but is available for the undelivered element of a multiple element arrangement, sales revenue is recognized on the date the product is shipped, using the residual method, with the portion deferred that is related to undelivered elements. Undelivered elements related to software are generally restricted to post contract support and training and education. The amount of revenue allocated to these undelivered elements is based on the VSOE of fair value for those undelivered elements. Deferred revenue due to undelivered elements is recognized ratably over the service period or when the service is completed. When VSOE of fair value is not available for the undelivered element of a multiple element arrangement, sales revenue for the entire sales contract value is generally recognized ratably over the service period of the undelivered element, generally 12 months or when the service is completed in accordance with the subscription method.

The application of revenue recognition standards requires judgment, including whether a software arrangement includes multiple elements, and if so, whether VSOE of fair value exists for those elements. Changes to the elements in a software arrangement, the ability to identify VSOE for those elements, the fair value of the respective elements, and changes to a product’s estimated life cycle could materially impact the amount of our earned and unearned revenue. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products.

Product revenue

Our product revenue is generated predominantly from the sales of measurement and automation products. Our products consist of application software and hardware components together with related driver software.

Software maintenance revenue

Software maintenance revenue is post contract customer support that provides the customer with unspecified upgrades/updates and technical support.

Shipping and handling costs

Our shipping and handling costs charged to customers are included in net sales, and the associated expense is recorded in cost of sales.

Warranty reserve

We offer a one-year limited warranty on most hardware products and extended two or three-year warranties on a subset of our hardware products, which is included in the sales price of many of our products. Provision is made for estimated future warranty costs at the time of the sale for the estimated costs that may be incurred under the basic limited warranty. Our estimate is based on historical experience and product sales.

The warranty reserve for the years ended December 31, 2013, 2012 and 2011 was as follows:

(In thousands)
		2013		2012		2011
Balance at the beginning of the period	$	1,435	$	1,271	$	921
Accruals for warranties issued during the period		3,737		2,270		2,954
Settlements made (in cash or in kind) during the period		(3,408)		(2,106)		(2,604)
Balance at the end of the period	$	1,764	$	1,435	$	1,271

Loss contingencies

We accrue for probable losses from contingencies including legal defense costs, on an undiscounted basis,  when such costs are considered probable of being incurred and are reasonably estimable. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary.

F-12

Advertising expense

We expense costs of advertising as incurred. Advertising expense for the years ended December 31, 2013, 2012 and 2011 was $13.7 million,  $14.4 million and $14.7 million, respectively.

Foreign currency translation

The functional currency for our international sales operations is the applicable local currency. The assets and liabilities of these operations are translated at the rate of exchange in effect on the balance sheet date and sales and expenses are translated at average rates. The resulting gains or losses from translation are included in a separate component of other comprehensive income. Gains and losses resulting from re-measuring monetary asset and liability accounts that are denominated in a currency other than a subsidiary’s functional currency are included in net foreign exchange loss and are included in net income.

Foreign currency hedging instruments

All of our derivative instruments are recognized on the balance sheet at their fair value. We currently use foreign currency forward and purchased option contracts to hedge our exposure to material foreign currency denominated receivables and forecasted foreign currency cash flows.

On the date the derivative contract is entered into, we designate the derivative as a hedge of the variability of foreign currency cash flows to be received or paid (“cash flow” hedge) or as a hedge of our foreign denominated net receivable positions (“other derivatives”). Changes in the fair value of derivatives that are designated and qualify as cash flow hedges and that are deemed to be highly effective are recorded in other comprehensive income. These amounts are subsequently reclassified into earnings in the period during which the hedged transaction is realized. The gain or loss on the other derivatives as well as the offsetting gain or loss on the hedged item attributable to the hedged risk is recognized in current earnings under the line item “Net foreign exchange loss”. We do not enter into derivative contracts for speculative purposes.

We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking various hedge transactions at the inception of the hedge. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions. We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the hedging instruments are highly effective in offsetting changes in cash flows of hedged items.

We prospectively discontinue hedge accounting if (1) it is determined that the derivative is no longer highly effective in offsetting changes in the fair value of a hedged item (forecasted transactions); or (2) the derivative is de-designated as a hedge instrument, because it is unlikely that a forecasted transaction will occur. When hedge accounting is discontinued, the derivative is sold and the resulting gains and losses are recognized immediately in earnings.

Income taxes

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position or our results of operations. In estimating future tax consequences, all expected future events are considered other than enactments of changes in tax laws or rates. We account for uncertainty in income taxes recognized in our financial statements using prescribed recognition thresholds and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on our tax returns. Our continuing policy is to recognize interest and penalties related to income tax matters in income tax expense.

F-13

Earnings per share

Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net income by the weighted average number of common shares and common share equivalents outstanding (if dilutive) during each period. The number of common share equivalents, which include stock options and restricted stock units (“RSUs”), is computed using the treasury stock method.

The reconciliation of the denominators used to calculate basic EPS and diluted EPS for the years ended December 31, 2013, 2012 and 2011 are as follows:

	Years ended December 31,
(In thousands)	2013	2012	2011
Weighted average shares outstanding-basic	124,558	121,973	119,836
Plus: Common share equivalents
Stock options, restricted stock units	1,013	1,004	1,384
Weighted average shares outstanding-diluted	125,571	122,977	121,220

Stock awards to acquire 43,640 shares, 986,503 shares, and 477,019 shares for the years ended December 31, 2013, 2012, and 2011 were excluded in the computations of diluted EPS because the effect of including the stock awards would have been anti-dilutive.

On January 21, 2011, our Board of Directors declared a 3 for 2 stock split which was effected as a stock dividend, and paid on February 21, 2011, to stockholders of record on February 4, 2011. All per share data and numbers of common shares, where appropriate, have been retroactively adjusted to reflect the stock split.

Stock-based compensation

We account for stock-based compensation plans, which are more fully described in Note 11 – Authorized shares of common and preferred stock and stock-based compensation plans, using a fair-value method and recognize the expense in our Consolidated Statement of Income.

Comprehensive income

Our comprehensive income is comprised of net income, foreign currency translation and unrealized gains and losses on forward and option contracts and securities available-for-sale. Comprehensive income for 2013, 2012 and 2011 was $82.2 million, $94.5 million and $91.3 million, respectively.

Recently Issued Accounting Pronouncements

In February 2013, the FASB issued Accounting Standards Update (“ASU”) No. 2013-02, Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income, which amends ASC 220, Comprehensive Income. The amended guidance requires entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. Additionally, entities are required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amended guidance does not change the current requirements for reporting net income or other comprehensive income. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. We adopted this update in the first quarter of 2013. The adoption of ASU No. 2013-02 did not have a significant impact on the Company’s consolidated financial statements, but did amend the disclosures for accumulated other comprehensive income reclassified into income.

In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which amends ASC 740, Income Taxes. The amendments provide guidance on the financial statement presentation of an unrecognized tax benefit, as either a reduction of a deferred tax asset or as a liability, when a net operating loss carryforward, similar tax loss, or a tax credit carryforward exists. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and may be applied on either a prospective or retrospective basis. The provisions are effective for the Company’s Form 10-K for the year ending December 31, 2014. We do not expect the adoption of these provisions to have a significant impact on the Company’s consolidated financial statements.

Note 3 – Fair value measurements 

We define fair value to be the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market that market participants may use when pricing the asset or liability.   

We follow a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value measurement is determined based on the lowest level input that is significant to the fair value measurement. The three values of the fair value hierarchy are the following:   

Level 1 – Quoted prices in active markets for identical assets or liabilities   

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly   

Level 3 – Inputs that are not based on observable market data   

Assets and liabilities measured at fair value on a recurring basis are summarized below:

We value our available-for-sale short-term investments based on pricing from third party pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. We classify all of our fixed income available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of our financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. We believe all of these sources reflect the credit risk associated with each of our available-for-sale short-term investments. Short-term investments available-for-sale consists of debt securities issued by states of the U.S. and political subdivisions of the U.S., corporate debt securities and debt securities issued by U.S. government organizations and agencies as well as debt securities issued by foreign governments. All short-term investments available-for-sale have contractual maturities of less than 35 months.  

Derivatives include foreign currency forward and option contracts. Our foreign currency forward contracts are valued using an income approach (Level 2) based on the spot rate less the contract rate multiplied by the notional amount. Our foreign currency option contracts are valued using a market approach based on the quoted market prices which are derived from observable inputs including current and future spot rates, interest rate spreads as well as quoted market prices of similar instruments. We consider counterparty credit risk in the valuation of our derivatives. However, counterparty credit risk did not impact the valuation of our derivatives during the year ended December 31, 2013. There were not any transfers in or out of Level 1 or Level 2 in the year ended December 31, 2013.  

Our foreign government bonds consist of German government sovereign debt denominated in Euro with maximum remaining maturities of 18 months. Our short-term investments do not involve sovereign debt from any other country in Europe.  

We did not have any items that were measured at fair value on a nonrecurring basis at December 31, 2013 and December 31, 2012.  

The carrying value of net accounts receivable and accounts payable contained in the Consolidated Balance Sheets approximates fair value.

 Note 4 – Derivative instruments and hedging activities  

We recognize all of our derivative instruments as either assets or liabilities in our statement of financial position at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, we designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation.  

We have operations in over 50 countries. Sales outside of the Americas accounted for approximately 59%, 60%, and 60% of our revenues during the years ended December 31, 201, 2012 and 2011, respectively. Our activities expose us to a variety of market risks, including the effects of changes in foreign currency exchange rates. These financial risks are monitored and managed by us as an integral part of our overall risk management program.  

We maintain a foreign currency risk management strategy that uses derivative instruments (foreign currency forward and purchased option contracts) to help protect our earnings and cash flows from fluctuations caused by the volatility in currency exchange rates. Movements in foreign currency exchange rates pose a risk to our operations and competitive position, since exchange rate changes may affect our profitability and cash flow, and the business or pricing strategies of our non-U.S. based competitors.  

The vast majority of our foreign sales are denominated in the customers’ local currency. We purchase foreign currency forward and option contracts as hedges of forecasted sales that are denominated in foreign currencies and as hedges of foreign currency denominated receivables. These contracts are entered into to help protect against the risk that the eventual dollar-net-cash inflows resulting from such sales or firm commitments will be adversely affected by changes in exchange rates. We also purchase foreign currency forward contracts as hedges of forecasted expenses that are denominated in foreign currencies. These contracts are entered into to help protect against the risk that the eventual dollar-net-cash outflows resulting from foreign currency operating and cost of revenue expenses will be adversely affected by changes in exchange rates.  

We designate foreign currency forward and purchased option contracts as cash flow hedges of forecasted revenues or forecasted expenses. In addition, we hedge our foreign currency denominated balance sheet exposures using foreign currency forward contracts that are not designated as hedging instruments. None of our derivative instruments contain a credit-risk-related contingent feature.  

F-17

Cash flow hedges  

  To help protect against the reduction in value caused by a fluctuation in foreign currency exchange rates of forecasted foreign currency cash flows resulting from international sales over the next one to three years, we have instituted a foreign currency cash flow hedging program. We hedge portions of our forecasted revenue and forecasted expenses denominated in foreign currencies with forward and purchased option contracts. For forward contracts, when the dollar strengthens significantly against the foreign currencies, the change in the present value of future foreign currency cash flows may be offset by the change in the fair value of the forward contracts designated as hedges. For option contracts, when the dollar strengthens significantly against the foreign currencies, the change in the present value of future foreign currency cash flows may be offset by the change in the fair value of the option contracts net of the premium paid designated as hedges. Our foreign currency purchased option contracts are purchased “at-the-money” or “out-of-the-money”. We purchase foreign currency forward and option contracts for up to 100% of our forecasted exposures in selected currencies (primarily in Euro, Japanese yen, Malaysian ringgit, British pound and Hungarian forint) and limit the duration of these contracts to 40 months or less.  

For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive income (“OCI”) and reclassified into earnings in the same line item (net sales, operating expenses, or cost of sales) associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings or expenses during the current period and are classified as a component of “net foreign exchange loss”. Hedge effectiveness of foreign currency forwards and purchased option contracts designated as cash flow hedges are measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the forecasted transaction’s terminal value.  

We held forward contracts with the following notional amounts:

(In thousands)		US Dollar Equivalent
		As of December 31, 2013		As of  December 31, 2012
Euro	$	75,886	$	84,770
Japanese yen		23,284		42,209
Hungarian forint		21,159		36,005
British pound		14,869		-
Malaysian ringgit		4,426		-
Total forward contracts notional amount	$	139,624	$	162,984

The contracts in the foregoing table had contractual maturities of 36 months or less at December 31, 2013 and December 31, 2012.  

At December 31, 2013, we expect to reclassify $157,000 of gains on derivative instruments from accumulated OCI to net sales during the next twelve months when the hedged international sales occur, $910,000 of gains on derivative instruments from accumulated OCI to cost of sales when the cost of sales are incurred and $409,000 of gains on derivative instruments from accumulated OCI to operating expenses during the next twelve months when the hedged operating expenses occur. Expected amounts are based on derivative valuations at December 31, 2013. Actual results may vary as a result of changes in the corresponding exchange rates subsequent to this date.  

We did not record any ineffectiveness from our hedges during the years ended December 31, 2013 and 2012.  

Other Derivatives  

Other derivatives not designated as hedging instruments consist primarily of foreign currency forward contracts that we use to hedge our foreign denominated net receivable or net payable positions to protect against the change in value caused by a fluctuation in foreign currency exchange rates. We typically attempt to hedge up to 90% of our outstanding foreign denominated net receivables or net payables and typically limit the duration of these foreign currency forward contracts to approximately 120 days. The gain or loss on the derivatives as well as the offsetting gain or loss on the hedge item attributable to the hedged risk is recognized in current earnings under the line item “net foreign exchange loss”. As of December 31, 2013 and December 31, 2012, we held foreign currency forward contracts with a notional amount of $70 million and  $69 million, respectively.

Note 7 – Intangible assets 

Intangible assets at December 31, 2013 and December 31, 2012 are as follows:

(In thousands)		December 31, 2013						December 31, 2012
		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount
Capitalized software development costs	$	48,947	$	(25,706)	$	23,241	$	45,064	$	(23,450)	$	21,614

	$	192,980	$	(110,670)	$	82,310	$	186,407	$	(92,494)	$	93,913

Software development costs capitalized during 2013, 2012, and 2011 were $15.6 million, $12.2 million, and $12.6 million, respectively, and related amortization expense was $14.0 million, $14.1 million, and $13.4 million, respectively. Capitalized software development costs for the years ended December 31, 2013, 2012, and 2011 included costs related to stock based compensation of $742,000, $519,000 and $539,000, respectively. The related amounts in the table above are net of fully amortized assets.

Amortization of capitalized software development costs is computed on an individual product basis for those products available for market and is recognized based on the product’s estimated economic life, generally three years. Acquired technology and other intangible assets are amortized over their useful lives, which range from three to eight years. Patents are amortized using the straight-line method over their estimated period of benefit, generally 10 to 17 years. Total intangible assets amortization expenses were $32 million, $28 million, and $25 million for the years ended December 31, 2013, 2012, and 2011, respectively.

F-21

Capitalized software development costs, acquired technology, patents and other had weighted-average useful lives of 1.8 years, 2.1 years, 4.0 years, and 2.3 years, respectively, as of December 31, 2013. The estimated future amortization expense related to intangible assets as of December 31, 2013 was as follows:

		Amount
		(In thousands)
2014	$	32,972
2015		23,050
2016		12,580
2017		5,521
2018		785
Thereafter		7,402
	$	82,310

The overall increase in our acquired technology and other intangible assets can be attributed to our acquisitions in 2012. See Note 17 – Acquisitions of Notes to Consolidated Financial Statements for additional discussion related to these acquisitions.

 Note 8 – Goodwill

The carrying amounts of goodwill for 2012 and 2013 are as follows:

		Amount
		(In thousands)
Balance as of December 31, 2011	$	130,747
Purchase price adjustments		(1,623)
Acquisitions		17,987
Foreign currency translation impact		147
Balance as of December 31, 2012	$	147,258
Purchase price adjustments		(1,463)
Foreign currency translation impact		725
Balance as of December 31, 2013	$	146,520

The excess purchase price over the fair value of assets acquired is recorded as goodwill. During 2013, we adjusted the purchase price for one of our 2012 acquisitions, which resulted in the reduction of goodwill by $1.5 million. As we have one operating segment, we allocate goodwill to one reporting unit for goodwill impairment testing. Goodwill is tested for impairment on an annual basis, and between annual tests if indicators of potential impairment exist, using a fair-value-based approach based on the market capitalization of the reporting unit. Our annual impairment test was performed as of February 28, 2013. No impairment of goodwill was identified during 2013 and 2012. Goodwill is deductible for tax purposes in certain jurisdictions.

A reconciliation of income taxes at the U.S. federal statutory income tax rate to our effective tax rate follows:

	Years Ended December 31,
	2013		2012		2011
U.S. federal statutory rate	35	%	35	%	35	%
Foreign taxes greater (less) than federal statutory rate	2		(5)		(7)

Nondeductible acquisition costs	-		2		-
Domestic production activities deduction	(1)		-		-
Other	2		-		1
Effective tax rate	17	%	22	%	15	%

As of December 31, 2013,  we had a federal net operating loss carryforward of $4.3 million which expires during the years 2030 to 2032, and federal tax credit carryforwards of $2.8 million which expire during the years 2019 to 2030. These carryforwards are subject to limitations following a change in ownership.

As of December 31, 2013, 15 of our subsidiaries had available, for income tax purposes, foreign net operating loss carryforwards of an aggregate of approximately $571 million, of which $2.7 million expires during the years 2018 to 2023 and $568 million of which may be carried forward indefinitely. Our tax valuation allowance relates primarily to our ability to realize certain of these foreign net operating loss carryforwards.

In 2003, we restructured the organization of our manufacturing operation in Hungary. The tax deductible goodwill in excess of book goodwill created by this restructuring resulted in our being required to record a gross deferred tax asset of $91 million. Because we did not expect to have sufficient taxable income in the relevant jurisdiction in future periods to realize the benefit of this deferred tax asset, a full valuation allowance was established. Following the approval of the merger of our Hungarian manufacturing operation with its Hungarian parent company in December 2007, we released $9.7 million, $8.7 million and $18.3 million in 2009, 2008 and 2007, respectively, of the valuation allowance previously established for the excess tax deductible goodwill to reflect the tax benefit we expected to realize in future periods.

Effective January 1, 2010, a new tax law in Hungary provided for an enhanced deduction for the qualified research and development expenses of NI Hungary Software and Hardware Manufacturing Kft. (“NI Hungary”). During the three months ended December 31, 2009, we obtained confirmation of the application of this new tax law for the qualified research and development expenses of NI Hungary. Based on the application of this new tax law to the qualified research and development expense of NI Hungary, we no longer expect to have sufficient future taxable income in Hungary to realize the benefits of these tax assets. As such, we recorded an income tax charge of $21.6 million during the three months ended December 31, 2009, $18.4 million of which was related to a valuation allowance on the previously recognized assets created by the restructuring and $3.2 million of which was related to tax benefits from other assets that we will no longer be able to realize as a result of this change. We do not expect to realize the tax benefit of the remaining assets created by the restructuring and therefore we had a full valuation allowance against those assets at December 31, 2013.

We have not provided for U.S. federal income and foreign withholding taxes on approximately $558 million of certain non-U.S. subsidiaries’ undistributed earnings as of December 31, 2013. These earnings would become subject to taxes of approximately $185 million, if they were actually or deemed to be remitted to the parent company as dividends or if we should sell our stock in these subsidiaries. We intend to permanently reinvest the undistributed earnings.

F-24

We account for uncertainty in income taxes recognized in our financial statements using prescribed recognition thresholds and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on our tax returns. We recognized no material adjustment to the liability for unrecognized income tax benefits. A reconciliation of the beginning and ending amount of unrecognized tax benefit is as follows:

(In thousands)		2013		2012
Balance at beginning of period	$	20,920	$	19,494
Additions based on tax positions related to the current year		3,290		3,150
Additions for tax positions of prior years		337		1,764
Reductions as a result of settlement with taxing authorities		(975)		(285)
Reductions as a result the lapse of the applicable statute of limitations		-		(2,256)
Reduction for tax positions of prior years		-		(947)
Balance at end of period	$	23,572	$	20,920

All of our unrecognized tax benefits at December 31, 2013 would affect our effective income tax rate if recognized.

We recognize interest and penalties related to income tax matters in income tax expense. During the years ended December 31, 2013 and 2012, we recognized interest expense related to uncertain tax positions of approximately $337,000 and $782,000, respectively.

The tax years 2006 through 2012 remain open to examination by the major taxing jurisdictions to which we are subject.  The Internal Revenue Service (“IRS”) commenced an examination of our U.S. income tax returns for 2010 and 2011 in the second quarter of 2013.

Earnings from our operations in Malaysia are free of tax under a tax holiday effective January 1, 2013. This tax holiday expires in 2027. If we fail to satisfy the conditions of the tax holiday, this tax benefit may be terminated early. As our Malaysia manufacturing operation is still in a start-up phase, the tax holiday did not result in any income tax benefit for the year ended December 31, 2013.

Note 10 – Comprehensive income

Our comprehensive income is comprised of net income, foreign currency translation, unrealized gains and losses on forward and option contracts and securities classified as available-for-sale.

Note 11 – Authorized shares of common and preferred stock and stock-based compensation plans  

Authorized shares of common and preferred stock

Following approval by the Company’s Board of Directors and stockholders, on May 14, 2013, the Company’s certificate of incorporation was amended to increase the authorized shares of common stock by 180,000,000 shares to a total of 360,000,000 shares.  As a result of this amendment, the total number of shares which the Company is authorized to issue is 365,000,000 shares, consisting of (i) 5,000,000 shares of preferred stock, par value $.01 per share, and (ii) 360,000,000 shares of common stock, par value $.01 per share.

Stock option plans  

Our stockholders approved the 1994 Incentive Stock Option Plan (the “1994 Plan”) in May 1994. At the time of approval, 13,668,750 shares of our common stock were reserved for issuance under this plan. In 1997, an additional 10,631,250 shares of our common stock were reserved for issuance under this plan, and an additional 1,125,000 shares were reserved for issuance under this plan in 2004. The 1994 Plan terminated in May 2005, except with respect to outstanding awards previously granted thereunder.  

Awards under the plan were either incentive stock options within the meaning of Section 422 of the Internal Revenue Code or nonqualified options. The right to purchase shares under the options vests over a five to ten-year period, beginning on the date of grant. Vesting of ten year awards may accelerate based on the Company’s previous year’s earnings and revenue growth but shares cannot accelerate to vest over a period of less than five years. Stock options must be exercised within ten years from date of grant. Stock options were issued with an exercise price which was equal to the market price of our common stock at the grant date. We estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock compensation expense to be recognized in future periods. During the years ended December 31, 2013, we did not make any changes in accounting principles or methods of estimates related to the 1994 Plan.  

Transactions under all stock option plans are summarized as follows:

	Number of shares under option		Weighted average exercise price
Outstanding at December 31, 2010	2,334,448	$	17.15

The aggregate intrinsic value of stock options at exercise, represented in the table above, was $8.3 million, $2.4 million and $13.0 million for the years ended December 31, 2013, 2012 and 2011, respectively. Total unrecognized stock-based compensation expense related to non-vested stock options was approximately $11,000 as of December 31, 2013, related to approximately 11,765 shares with a per share weighted average fair value of $13.81. We anticipate this expense to be recognized over a weighted average period of approximately 0.56 years.

		Outstanding and Exercisable by Price Range as of December 31, 2013

The weighted average remaining contractual life of options exercisable as of December 31, 2013 was 0.58 years. The aggregate intrinsic value of options outstanding as of December 31, 2013 was $3.9 million. The aggregate intrinsic value of options currently exercisable as of December 31, 2013 was $3.7 million. No options were granted in the years ended December 31, 2013, 2012 and 2011.

Restricted stock plan  

Our stockholders approved our 2005 Incentive Plan (the “2005 Plan”) in May 2005. At the time of approval, 4,050,000 shares of our common stock were reserved for issuance under this plan, as well as the number of shares which had been reserved but not issued under the 1994 Plan (our incentive stock option plan which terminated in May 2005), and any shares that returned to the 1994 Plan as a result of termination of options or repurchase of shares issued under such plan. The 2005 Plan, administered by the Compensation Committee of the Board of Directors, provided for granting of incentive awards in the form of restricted stock and RSUs to directors, executive officers and employees of the Company and its subsidiaries. Awards vest over a three,  five or ten-year period, beginning on the date of grant. Vesting of ten year awards may accelerate based on the Company’s previous year’s earnings and growth but ten year awards cannot accelerate to vest over a period of less than five years. The 2005 Plan terminated on May 11, 2010, except with respect to outstanding awards previously granted thereunder. There were 3,362,304 shares of common stock that were reserved but not issued under the 1994 Plan and the 2005 Plan as of May 11, 2010.  

Our stockholders approved our 2010 Incentive Plan (the “2010 Plan”) on May 11, 2010. At the time of approval, 3,000,000 shares of our common stock were reserved for issuance under this plan, as well as the 3,362,304 shares of common stock that were reserved but not issued under the 1994 Plan and the 2005 Plan as of May 11, 2010, and any shares that are returned to the 1994 Plan and the 2005 Plan as a result of forfeiture or termination of options or RSUs or repurchase of shares issued under these plans. The 2010 Plan, administered by the Compensation Committee of the Board of Directors, provides for granting of incentive awards in the form of restricted stock and RSUs to employees, directors and consultants of the Company and employees and consultants of any parent or subsidiary of the Company. Awards vest over a three,  five or ten-year period, beginning on the date of grant. Vesting of ten year awards may accelerate based on the Company’s previous year’s earnings and growth but ten year awards cannot accelerate to vest over a period of less than five years. There were 3,318,042 shares available for grant under the 2010 Plan at December 31, 2013.  

We estimate potential forfeitures of RSUs and adjust compensation cost recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock compensation expense to be recognized in future periods. During the year ended December 31, 2013, we did not make any changes in accounting principles or methods of estimates related to the 2010 Plan.

Total unrecognized stock-based compensation expense related to non-vested RSUs was approximately $89.4 million as of December 31, 2013, related to 3,506,562 shares with a per share weighted average fair value of $26.23. We anticipate this expense to be recognized over a weighted average period of approximately 5.43 years.

Employee stock purchase plan  

Our employee stock purchase plan permits substantially all domestic employees and employees of designated subsidiaries to acquire our common stock at a purchase price of 85% of the lower of the market price at the beginning or the end of the purchase period. The plan has quarterly purchase periods generally beginning on February 1, May 1, August 1 and November 1 of each year. Employees may designate up to 15% of their compensation for the purchase of common stock under this plan. On May 10, 2011, our stockholders approved an additional 3,000,000 shares for issuance under our employee stock purchase plan, and at December 31, 2013, we had 1,380,751 shares of common stock reserved for future issuance under this plan. We issued 1,191,599 shares under this plan in the year ended December 31, 2013. The weighted average purchase price of the employees’ purchase rights was $22.48 per share and was estimated using the Black-Scholes model with the following assumptions: 

	2013	2012	2011
Dividend expense yield	0.5%	0.5%	0.4%
Expected life	3 months	3 months	3 months
Expected volatility	25%	40%	44%
Risk-free interest rate	0.1%	0.1%	0.1%

During the year ended December 31, 2013, we did not make any changes in accounting principles or methods of estimates with respect to the employee stock purchase plan.  

Weighted average, grant date fair value of purchase rights granted under the Employee Stock Purchase Plan are as follows:

	Number of Shares		Weighted average fair value
2011	940,703	$	6.56
2012	1,122,483	$	5.93
2013	1,191,599	$	5.64

Authorized Preferred Stock and Preferred Stock Purchase Rights Plan  

We have 5,000,000 authorized shares of preferred stock. On January 21, 2004, our Board of Directors designated 750,000 of these shares as Series A Participating Preferred Stock in conjunction with its adoption of a Preferred Stock Rights Agreement (the “Rights Agreement”) and declaration of a dividend of one preferred share purchase right (a “Right”) for each share of common stock outstanding held as of May 10, 2004 or issued thereafter. Each Right will entitle its holder to purchase one one-thousandth of a share of National Instruments’ Series A Participating Preferred Stock at an exercise price of $200, subject to adjustment, under certain circumstances. The Rights Agreement was not adopted in response to any effort to acquire control of National Instruments.  

F-28

The Rights only become exercisable in certain limited circumstances following the tenth day after a person or group announces acquisitions of or tender offers for 20% or more of our common stock. In addition, if an acquirer (subject to certain exclusions for certain current stockholders of National Instruments, an “Acquiring Person”) obtains 20% or more of our common stock, then each Right (other than the Rights owned by an Acquiring Person or its affiliates) will entitle the holder to purchase, for the exercise price, shares of our common stock having a value equal to two times the exercise price. Under certain circumstances, our Board of Directors may redeem the Rights, in whole, but not in part, at a purchase price of $0.01 per Right. The Rights have no voting privileges and are attached to and automatically traded with our common stock until the occurrence of specified trigger events. The Rights will expire on the earlier of May 10, 2014 or the exchange or redemption of the Rights.  

There were not any shares of preferred stock issued and outstanding at December 31, 2013 and December 31, 2012.

Stock repurchases and retirements

       From time to time, our Board of Directors has authorized various programs to repurchase shares of our common stock depending on market conditions and other factors. We did not make any purchases under this program during the year ended December 31, 2013. At December 31, 2013, there were 3,932,245 shares remaining available for repurchase under this program. This repurchase program does not have an expiration date.  

Note 12 – Employee retirement plan

We have a defined contribution retirement plan pursuant to Section 401(k) of the Internal Revenue Code. Substantially all domestic employees with at least 30 days of continuous service are eligible to participate and may contribute up to 15% of their compensation. The Board of Directors has elected to make matching contributions equal to 50% of employee contributions, which may be applied to a maximum of 6% of each participant’s compensation. Employees are eligible for matching contributions after one year of continuous service. Company contributions vest immediately. Our policy prohibits participants from direct investment in shares of our common stock within the plan. Company contributions charged to expense were $5.8 million,  $5.3 million and $4.7 million in 2013, 2012 and 2011, respectively.

Note 13  –Segment information

We determine operating segments using the management approach. The management approach designates the internal organization that is used by management for making operating decisions and assessing performance as the source of our operating segments. It also requires disclosures about products and services, geographic areas and major customers.  

We have defined our operating segment based on geographic regions. We sell our products in four geographic regions. Our sales to these regions share similar economic characteristics, similar product mix, similar customers, and similar distribution methods. Accordingly, we have elected to aggregate these four geographic regions into a single operating segment. Revenue from the sale of our products which are similar in nature and software maintenance are reflected as total net sales in our Consolidated Statements of Income.  

F-29

Total net sales, operating income, interest income and long-lived assets, classified by the major geographic areas in which we operate, are as follows:

Note 14 - Debt

On May 9, 2013, we entered into a Loan Agreement (the “Loan Agreement”) with Wells Fargo Bank, National Association (the “Lender”). The Loan Agreement provides for a $50 million unsecured revolving line of credit with a scheduled maturity date of May 9, 2018 (the “Maturity Date”). Proceeds of loans made under the Loan Agreement may be used for working capital and other general corporate purposes. We may prepay the loans under the Loan Agreement in whole or in part at any time without premium or penalty. Certain of our existing and future material domestic subsidiaries are required to guaranty our obligations under the Loan Agreement. As of December 31, 2013, we had $50 million available for borrowings under this revolving line of credit.

F-30

The loans bear interest, at our option, at a base rate determined in accordance with the Loan Agreement, plus a spread of 0.0% to 0.5%, or a LIBOR rate plus a spread of 1.125% to 2.0%, in each case with such spread determined based on a ratio of consolidated indebtedness to EBITDA, determined in accordance with the Loan Agreement. Principal, together with all accrued and unpaid interest, is due and payable on the Maturity Date. We are also obligated to pay a quarterly commitment fee, payable in arrears, based on the available commitments at a rate of 0.175% to 0.300%, with such rate determined based on the ratio described above. The Loan Agreement contains customary affirmative and negative covenants. The affirmative covenants include, among other things, delivery of financial statements, compliance certificates and notices; payment of taxes and other obligations; maintenance of existence; maintenance of properties and insurance; and compliance with applicable laws and regulations. The negative covenants include, among other things, limitations on indebtedness, liens, mergers, consolidations, acquisitions and sales of assets, investments, changes in the nature of the business, affiliate transactions and certain restricted payments. The Loan Agreement also requires us to maintain a ratio of consolidated indebtedness to EBITDA equal to or less than 3.25 to 1.00, and a ratio of consolidated EBITDA to interest expense greater than or equal to 3.00 to 1.00, in each case determined in accordance with the Loan Agreement.

The Loan Agreement contains customary events of default including, among other things, payment defaults, breaches of covenants or representations and warranties, cross-defaults with certain other indebtedness, bankruptcy and insolvency events, judgment defaults and change in our control, subject to grace periods in certain instances. Upon an event of default, the lender may declare all or a portion of the outstanding obligations payable by us to be immediately due and payable and exercise other rights and remedies provided for under the Credit Agreement. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the Loan Agreement at a per annum rate of interest equal to 2.00% above the otherwise applicable interest rate. As of December 31, 2013, we were in compliance with all covenants in the Loan Agreement.

Note 15 – Commitments and Contingencies  

We have commitments under non-cancelable operating leases primarily for office facilities throughout the world. Certain leases require us to pay property taxes, insurance and routine maintenance, and include escalation clauses. Future minimum lease payments as of December 31, 2013, for each of the next five years are as follows:

		Amount
		(In thousands)
2014	$	19,786
2015		16,664
2016		11,319
2017		7,181
2018		5,545
Thereafter		6,031
	$	66,526

Rent expense under operating leases was approximately $19 million, $17 million and $16 million for the years ended December 31, 2013, 2012 and 2011, respectively.

As of December 31, 2013, we had non-cancelable purchase commitments with various suppliers of customized inventory and inventory components totaling approximately $11 million over the next twelve months.  

As of December 31, 2013, we had outstanding guarantees for payment of customs and foreign grants totaling approximately $5.2 million, which are generally payable over the next twelve months.  

From November 1999 to May 2011, we sold products to the U.S. government under a contract with the General Services Administration ("GSA"). Our previous contract with GSA contained a price reduction or "most favored customer" pricing provision. During 2011 and 2012, we had been in discussions with GSA regarding our compliance with this pricing provision and provided GSA with information regarding our pricing practices. In 2011, GSA conducted an on-site review of our GSA pricing practices and orally informed us that GSA did not agree with our previous determination of the potential non-compliance amount. GSA subsequently requested that we conduct a further analysis of the non-compliance amount based upon a methodology that GSA proposed. This analysis resulted in calculated overpayments (including added interest) by GSA to us of approximately $13.1 million. During the quarter ended September 30, 2011, we established an accrual for $13.1 million which represented the amount of the loss contingency that was reasonably estimable at that time. On June 6, 2012, we entered into a Settlement Agreement with GSA and paid approximately $11.8 million in settlement of the foregoing matters. Due to the complexities of conducting business with GSA, the relatively small amount of revenue we realized from our previous GSA contract, and our belief that we can continue to sell our products to U.S. government agencies through other contracting methods, we cancelled our contract with GSA in April 2011, effective May 2011. To date, we have not experienced any material adverse impact on our results of operations as a result of the cancellation of our previous GSA contract.

Note 16 – Litigation  

We are not currently a party to any material litigation. However, in the ordinary course of our business, we are involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them. We also periodically receive notifications from various third parties related to alleged infringement of patents or intellectual property rights, commercial disputes or other matters. No assurances can be given with respect to the extent or outcome of any future litigation or dispute.

Note 17 - Acquisitions

In the fourth quarter of 2012, we acquired three privately held companies, including Signalion. The companies acquired included a wireless product company with a focus on test and measurement, a network measurements company with an emphasis on next-generation characterization and analysis tools for the high-frequency electronics and communication market, and a leading electrical engineering products company serving students, universities and OEMs worldwide with technology based educational design tools. These acquisitions are expected to accelerate the deployment of our RF and wireless technologies, accelerate our expansion into digital and embedded education, gain access to fast turn, low cost development and manufacturing capabilities, and increase our position in semiconductor academic programs. The combined purchase price of the acquisitions was $42 million consisting of $25 million cash, net of $5 million cash received, and $12 million in future cash payments. We funded the cash portion of the purchase price from existing cash balances.

The allocation of the purchase price was determined using the fair value of assets and liabilities acquired as of the respective closing dates. Our consolidated financial statements include the operating results from the dates of acquisition. Pro-forma results of operations have not been presented because the effects of those operations were not material. The finalization of our purchase price allocation during the fourth quarter of 2013 resulted in a net increase in tangible assets of $1.5 million, a decrease in intangible assets of $1,000, and a decrease in goodwill of approximately $1.5 million. The following table summarizes the allocation of the purchase price of these acquisitions resulting from all adjustments as of December 31, 2013:

		Amount
		(In thousands)
Net tangible assets acquired	$	9,563
Amortizable intangible assets		24,136
Deferred tax liability		(7,899)
Goodwill		16,524
Total	$	42,324

Goodwill is not deductible for tax purposes. Amortizable intangible assets have useful lives of 4 months to 5 years from the date of acquisition. These assets are not deductible for tax purposes for two of the three acquisitions.

AWR Corporation

On June 30, 2011, we acquired all of the outstanding shares of AWR Corporation (AWR), a privately held company that is a leading supplier of electronic design automation software for designing radio frequency and high-frequency components and systems for the semiconductor, aerospace and defense, communications and test equipment industries. The acquisition is expected to improve customer productivity through increased interoperability between upfront design and validation and production test functions. The purchase price of the acquisition was $66 million consisting of $54 million in cash and a three-year earn-out arrangement. We funded the purchase price from existing cash balances. The range of potential undiscounted payments that we could be required to make under the earn-out arrangement is between $0 and $29 million and are payable if AWR achieves certain revenue and operating income targets. The fair value of the earn-out arrangement was estimated at $12 million using the income approach, the key assumptions which included probability-weighted revenue and operating expense growth projections. In July 2012, the Company paid the amount due to the former AWR shareholders based on the first earn-out year performance of AWR. The amount paid was $3.3 million, and it is being recorded as a reduction of the earn-out liability. We re-measure the fair value of the earn-out liability each quarter. In the fourth quarter of 2012, we increased the acquisition earn out accrual by $6.8 million as AWR’s performance exceeded our prior expectations, and in the first quarter of 2013, we subsequently decreased this accrual by $1.3 million. In the third quarter of 2013, we made the second payment to AWR of $14 million. At December 31, 2013, the remaining earn-out accrual was valued at zero. 

F-32

The allocation of the purchase price was determined using the fair value of assets and liabilities acquired as of June 30, 2011. The finalization of our purchase price allocation during the three months ended June 30, 2012 resulted in an increase in acquired deferred tax assets and a decrease in goodwill of approximately $1.6 million. Our consolidated financial statements include the operating results from the date of acquisition.  Pro-forma results of operations have not been presented because the effects of those operations were not material. The following table summarizes the allocation of the purchase price of AWR:

		Amount
		(In thousands)
Net tangible assets acquired	$	10,718
Amortizable intangible assets		31,685
Deferred tax liability		(8,387)
Goodwill		32,379
Total	$	66,395

Goodwill is not deductible for tax purposes. Amortizable intangible assets have useful lives of 5 years from the date of acquisition.

Phase Matrix Inc.

On May 20, 2011, we acquired all of the outstanding shares of Phase Matrix, Inc. (PMI), a privately held company that designs and manufactures radio frequency and microwave test and measurement instruments, subsystems and components. The acquisition is expected to speed our deployment of high-performance RF and wireless technologies to our production test and R&D customers. The purchase price of the acquisition was $40.7 million consisting of $38.9 million in cash and $1.8 million in shares of our common stock. We funded the cash portion of the purchase price from existing cash balances.

The allocation of the purchase price was determined using the fair value of assets and liabilities acquired as of May 20, 2011. Our consolidated financial statements include the operating results from the date of acquisition. Pro-forma results of operations have not been presented because the effects of those operations were not material. The following table summarizes the allocation of the purchase price of Phase Matrix, Inc.:

		Amount
		(In thousands)
Net tangible assets acquired	$	5,624
Amortizable intangible assets		8,331
Goodwill		26,725
Total	$	40,680

Goodwill is deductible for tax purposes. Amortizable intangible assets have useful lives which range from 9 months to 8 years from the date of acquisition. These assets are also deductible for tax purposes.

Note 18 – Subsequent events  

We have evaluated subsequent events through the date the financial statements were issued.  

On January 30, 2014, our Board of Directors declared a quarterly cash dividend of $0.15 per common share, payable March 10, 2014, to stockholders of record on February 18, 2014.
