PART I

Item 1. Business:

        International Business Machines Corporation (IBM or the company) was incorporated in the State of New York on June 16, 1911, as the Computing-Tabulating-Recording Co. (C-T-R), a consolidation of the Computing Scale Co. of America, the Tabulating Machine Co. and The International Time Recording Co. of New York. Since that time, IBM has focused on the intersection of business insight and technological innovation, and its operations and aims have been international in nature. This was signaled over 85 years ago, in 1924, when C-T-R changed its name to International Business Machines Corporation. And it continues today: The company creates business value for clients and solves business problems through integrated solutions that leverage information technology and deep knowledge of business processes. IBM solutions typically create value by reducing a client's operational costs or by enabling new capabilities that generate revenue. These solutions draw from an industry leading portfolio of consulting, delivery and implementation services, enterprise software, systems and financing.

STRATEGY

        DespiteIBM's strategy is one of innovation, transformation and a constant evolution to higher value. The company delivers innovative solutions, software and infrastructure to improve client outcomes. The company helps enterprises apply technology to capture new value across their entire organizations, and it provides a differentiated client experience through a highly engaged and skilled global workforce and a broad ecosystem of partners. The ultimate goal of this strategy is to deliver on IBM's purpose of making our company essential to clients, employees, partners, investors and communities.

        Three strategic imperatives shape our approach as we continuously transform IBM and align the volatilitycompany for higher value.

1. Make Markets by Transforming Industries and Professions with Data

        The emergence of big data as the informationworld's new natural resource is the phenomenon of our time. It is being fueled by the proliferation of mobile devices, the rise of social media and the infusion of technology (IT) industry over the past decade, IBM has consistently delivered strong performance,into all things and processes. Today, enterprises must harness data to create competitive advantage. The value for enterprises increases as they apply more sophisticated analytics across more disparate data sources. Their real-time use of data will increasingly become a competitive differentiator. Enterprises will also need cognitive computing capabilities as data continues to grow in all dimensions. Therefore, IBM's strategy is to make markets by transforming industries and professions with a steady track record of sustained earnings per share growth and cash generation.data. The company has shiftedinvested more than $22 billion, including $15 billion on more than 30 acquisitions, to build its capabilities in big data and analytics. One third of IBM's research is focused on data, analytics and cognitive computing. The company is investing $1 billion in Watson solutions to build out the next era of cognitive systems and services. In 2013, the company realized $15.7 billion in business mix, exiting certain segments while increasing its presenceanalytics revenue. The original target for this business was to achieve $16 billion in higher-value areas such revenue in 2015—as services, software and integrated solutions. As parta result of this shift,performance the company has acquired more than 140 companies since 2000, complementingtaken its 2015 objective for business analytics revenue to $20 billion.

2. Remake Enterprise IT for the Era of Cloud

        Enterprises are increasingly relying on cloud, which is being fueled by abundant bandwidth, the emergence of standards and scaling its portfolio of products and offerings.

        IBM's strategy of delivering high value solutionsthe demand for consumability. They are benefitting from cloud by using it to enterprise clients has yielded consistent business results. Working with enterprise clients across the full spectrum oftransform their business and technical opportunities, IBM delivers leadership innovation in technology, high value solutions and insights that improve client and industry outcomes. A highly engaged, global workforce with deep technicalIT and business skills, teamedprocesses into digital services, to reinvent their core business processes and to drive innovation. Enterprises are integrating public and private clouds with back-end systems to create hybrid, dynamic environments. They will increasingly need to manage their cloud environments with the same rigor as an unmatched ecosystem of partners provides a world-class client experience.

        These priorities reflect a broad shift in client spending toward innovation and efficiency, as companies seek higher levels of business value from their IT investments. IBM has been able to deliver this enhanced client value thanks to its industry expertise, understanding of clients' businesses, sustained investment in core and applied research and development (R&D), global reach and the breadth and depth of the company's capabilities.

        New types of solutions, new market opportunities and new decision makers are emerging as clients look to make use of technology to generate innovation and competitive advantage. These opportunities are driven by a new era of computing that is enabled by analytics, cloud computing, Big Data, mobility, social computing and supported by enterprise grade security solutions. The company'son-premise datacenter. Therefore, IBM's strategy is to establish leadershipremake enterprise IT

for the era of cloud. The company has invested over $6 billion to acquire more than 15 companies related to cloud, and is investing more than $1 billion to expand its global footprint to 40 datacenters worldwide. IBM now has more than 100 SaaS offerings, and IBM cloud supports 24 of the top 25 Fortune 500 companies. All of this drove $4.4 billion of revenue for cloud-based solutions in 2013.

3. Enable "Systems of Engagement" for Enterprises and Lead by Example.

        Social, mobile and unprecedented access to data are changing how individuals are understood and engaged. A new class of individual is emerging: one that is empowered with knowledge, enriched by networks and expects value in return for its information. Enterprises must create a systematic approach to engage this new eraclass of smarter computing—computing thatindividual and increase its speed and responsiveness by becoming mobile. Interactions need to be personalized to offer more value. In addition, enterprises will benefit from securing information and increasing trust. Therefore, IBM's strategy is designedto enable "systems of engagement" for Big Data, built on software-defined environmentsenterprises; and open—the company is leading by example. IBM has acquired 20 companies related to mobile, social and security. IBMers are collaborating in order to enhancemore than 200,000 internal social communities and 85 percent of IBM's sellers use the value we deliver, create new marketscompany's Sales Connect portal. In 2013, the company's mobile, social and engage new clients.security portfolio generated double-digit revenue growth with mobile increasing 69 percent, security 19 percent and social business 45 percent.

        To capture the opportunities arising from these market trends,strategic imperatives, IBM is focused on four key growth initiatives: Smarter Planet, Growth Markets, Business Analytics, Cloud Computing and Optimization and Cloud Computing. Each initiative represents a significant growth opportunity with attractive profit margins for IBM.Growth Markets.

Smarter Planet

        Smarter Planet is IBM's vision ofstrategy to lead in a technology-enabled world that is more instrumented, interconnected and intelligent than ever before, enablingallowing people and organizations to tackleaddress significant

business and societal challenges. At the heart of this vision is the opportunitystrategy are solutions that drive innovation and outcomes for meaningful innovation—exploring and clients—extending the boundaries of businesses, industries and communities. It'sIt is about helping the company's clients become better at what they do for their clients. IBM's strategy is to accelerate progress toward a "smarter planet" by equipping clients with thecustomers. IBM does this through advanced, integrated capabilities they need to thrive in this exciting new world that is unfolding before us—solutions based on capabilities such as analytics for business and physical systems, cloud computing, mobile, social business and business process management, social business, mobile computing and cloud computing.management.

        IBM has continuedcontinues to deepen its commitment to understanding and delivering on the promise of Smarter Planet for both line of business andexecutives (CFOs, CHROs, CMOs, etc.) as well as IT executives across a broad range of industries. AnIBM's industry-based approach is central toand solutions are grounded in a deep understanding of the strategy, since every industry confronts a distinct set of challenges and opportunities that are confronting companies and executives in today's constantly transforming world.various industries. Whether "smarter"'smarter' means helping a bank to retain more customers through world-class mobile solutions, a hospital group to deliver improved healthcare,highly individualized care coordinated with social services, a local government to easeanticipate and alleviate traffic congestion before it happens, or a retail chain to executeprovide a successful cross-channel campaign,seamless customer experience across multiple channels, IBM is aggressively developing and investing in a portfolio of replicable industry solutions that helps theseto help clients achieve their goals.goals and drive important outcomes for their customers.

        Three initiativesThere are several areas of focus within the Smarter Planet strategy, including IBM's Social Business, MobileFirst, Smarter Commerce and Smarter Cities initiatives.

        IBM's Social Business initiative helps clients integrate social capabilities across core business processes to drive measurable business results. The Social Business initiative can unlock the intrinsic knowledge of people within an organization to help companies fuel customer-centric innovation, improve productivity and expand sales, loyalty and advocacy. To capitalize on the new market opportunities that arise from a digital economy, IBM Social Business can let clients apply increasingly sophisticated analytics to gain actionable insight and to more effectively engage with customers. Behavioral, human data is the newest form of data and can be used to build a stronger, more agile workforce and reinvent human capital management by applying behavioral sciences across the talent

lifecycle. The Social Business initiative is powered by world class IBM services and software, developed organically by IBM and through acquisitions.

        In 2013, the company launched IBM MobileFirst, a unified approach to help clients and partners deliver best-in-class mobile solutions, take advantage of more commercial opportunities and provide a superior customer experience. IBM has a breadth of expertise and technology to help organizations efficiently build and deploy mobile applications, maintain visibility and control over their mobile infrastructure, engage customers in context and transform the value chain in ways that can drive significant value illustrategrowth and return on investment. The company can help its clients achieve these goals through a complete portfolio of IBM mobile software, services and industry expertise. Throughout 2013, IBM invested in core mobile enterprise capabilities such as IBM Worklight and IBM Rational, while rounding out its portfolio with strategic acquisitions such as Fiberlink, Trusteer, Xtify and The Now Factory. Integrated with 270 patents in wireless innovations and strengthened by thousands of mobile specialists from IBM Mobile Enterprise Services and IBM Interactive, the company has already helped more than 1,000 clients become more mobile enterprises.

        In addition to Social and Mobile, IBM's deep commitment to building a smarter planet:planet can be seen in the ongoing efforts around Smarter Commerce and Smarter Cities and Social Business.Cities. IBM's Smarter Commerce model integratescan integrate and transformstransform how companies manage and adapt their buy, market, sell and service processes placingto place the customer squarelyexperience at the center of their business. IBM's Smarter Cities initiative enableshelps federal, state and local governments to make smarterbetter decisions, anticipate issues and coordinate resources across agencies more effectively while deliveringand deliver citizen-centric services that underpincan drive sustainable economic growth. IBM's Social Business initiative helps clients integrate social technologies and practices into their front-end processes to more effectively create and share knowledge to accelerate innovation, improve customer service, and build a smarter workforce. Each of these initiatives is powered by market-leading IBM innovations and software, developed both by IBM and through acquisitions.

Growth Markets

        The company has benefited from its investments over the past several years in the growth markets. The focus now is on geographic expansion of IBM's presence; on selected industries of the highest impact and opportunity; on countries' build-outs of infrastructure aligned with their national agendas; and, on creating markets and new business models to serve the different requirements that exist in these emerging countries. The company's effort in developing new growth markets within the African continent is a good example of this focus. Many of these initiatives are leading-edge, both in technologies and business models, and are delivering both increased revenue and margin expansion.

        In order to support this growth, IBM continues to invest significantly in these markets to expand capacity, to develop talent and to deepen its R&D capabilities on the ground. At the same time, IBM continues to leverage talent across the growth markets under its globally integrated enterprise model to the benefit of both its clients and the company worldwide.

Business Analytics and Optimization

        Business Analytics and Optimization (BAO) is the category of software, systems and services that helphelps organizations take advantage of all thebig data available to them formake better and faster decision makingdecisions and process optimization. Thisoptimize processes. Big data includes both enterprise data, that is being labeled "Big Data," which iscontent and new data of extreme volume, data being generated at a high velocity,from both structured and newer varieties of data likeunstructured sources: in previously unimaginable volumes (petabytes), with huge variety (from blogs, tweets, pictures, videos unstructured text created byand text), at high velocity (machine-to-machine data from the explosionInternet of social media websitesthings) and the instrumentation of nearly everything. BAO iswith decreasing veracity (from uncertain or incomplete sources). Big data and analytics are core to achieving a smarter planet,the Smarter Planet strategy, helping data-savvy, insight-driven leaders of this new information-centric and insight-driven worldto infuse intelligence into business decisions, processes and client interactions for faster actions and better outcomes.

The company's approach to big data and analytics ishelps organizations to ensure clients have complete end-to-end solutions across industries and functional focus areas like finance, sales, marketing, operations and risk. These solutions are designedsucceed in their industries. IBM recommends organizations do three things to help organizations: 1) align around all their data—both traditional and big data—and establish a strong information foundation; 2) apply analytics to their data so they can anticipate and shape business outcomes, identify patterns and gain insights into future performance; 3) enable workers on the front lines who collectively make thousands and even millions of decisions daily with insight that is immediately actionable so they can make the best possible decision—decisions like what claims to fast track in an insurance call center, or what offer is the best for each individual customer who calls a call center; and 4) createbe successful. First, build a culture that takes action oninfuses analytics everywhere. Second, be proactive about the privacy, security and that truly transforms.governance of their data. Third, invest in the right platform and solutions to harness and analyze all of their data for new insights and outcomes.

        IBM is committed to continually innovating across the spectrum of analyticbig data and analytics capabilities, solutions, systems, research, services, deployment and skills.

Growth Markets

        IBM continues to invest in growth markets where many countries and companies are embracing big data, mobile, social and cloud, often at faster rates than mature countries. In China, for example, 32 percent of consumers make their purchases online, compared to only 14 percent of consumers globally. In Africa, 18 percent of the continent's GDP is expected to be handled through mobile money transfers by 2015, while in Singapore, citizens spend 40 minutes on average each day on Facebook, compared to less than 25 minutes in the United States. IBM is helping clients in growth markets capitalize on these trends. For example:

•

In Mexico, IBM is using its analytics tools to enable Banorte-Ixe Bank to know and service its more than 13 million customers as individuals.



•

Using IBM's Big Data technologies and predictive analytics, Da Nang's (Vietnam) traffic control center is better forecasting and preventing potential congestion and better coordinating city responses to issues like accidents and adverse weather.



•

In Saudi Arabia, the company developed a public health solution for disease management that was implemented with the Saudi Ministry of Health to help manage the risk of infectious and communicable diseases across the Kingdom.



•

Faced with rising fuel costs and a goal to reduce greenhouse emissions, Jet Airways, India's premier international airline, turned to IBM to more accurately calculate, track and report aircraft emissions and reduce fuel usage.

IBM continues to build out its shared services facilities and talent to support its clients in growth markets. In China, the company has increased its Big Data software skills, and it will leverage an IBM Integrated Managed Services Centre to capture the significant growth in cloud. In November 2013, IBM opened its first Africa Research Lab in Kenya, IBM's 12th lab worldwide. The facility will conduct applied and exploratory research into the challenges Africa faces, and deliver commercially viable solutions to help improve the lives of people across the continent.

Summary

        IBM's strategy is one of innovation, transformation and a constant evolution to higher value. The company has steadily remixed its portfolio and business model to reflect its strategic beliefs and pursue its growth initiatives. IBM has a balanced history of exiting commodity businesses that no longer fit the high-value model while investing in strategic acquisitions and organic capabilities. In 2013, the company invested $3.1 billion for acquisitions, $3.8 billion in net capital expenditures and $6.2 billion in research and development. The company has acquired more than 150 companies since 2000 to bolster its portfolio in areas like big data and analytics, cloud and systems of engagement.

        As the company looks ahead to 2014 and beyond, it will continuously transform itself to take advantage of new opportunities and pursue bold new plays in areas such as Watson solutions, new offerings for big data and analytics, the mobile enterprise and high-value cloud services. IBM will continue to deliver differentiated client value based on its sustained investments in research and development, its engaged employee base, industry expertise, global reach, and the breadth and depth of the company's technologies and capabilities.

BUSINESS MODEL

        The company's business model is built to support two principal goals: helping enterprise clients to become more innovative, efficient and competitive through the application of business insight and IT solutions; and providing long-term value to shareholders. The business model has been developed over time through strategic investments in capabilities and technologies that have superior long-term growth and profitability prospects based on the value they deliver to clients.

        The company's global capabilities include services, software, systems, fundamental research and related financing. The broad mix of businesses and capabilities are combined to provide integrated solutions to the company's clients.

        The business model is resilient, adapting to the continuously changing market and economic environment. The company continues to divest certain businesses and strengthen its position through strategic organic investments and acquisitions in higher- value segments like business analytics, Smarter Planet and cloud computing.higher-value areas. In addition, the company has transformed itself into a globally integrated enterprise which has improved overall productivity and is driving investment and expanding participation in the world's fastest growing markets.

        This business model, supported by the company's financial model, has enabled the company to deliver strong earnings, cash flows and returns to shareholders over the long term.

BUSINESS SEGMENTS AND CAPABILITIES

        The company's major operations consists of five business segments: Global Technology Services and Global Business Services, which the company collectively calls Global Services, and Software, Systems and Technology and Global Financing.

        Global Services is a critical component of the company's strategy of providing IT infrastructure and business insight and solutions to clients. While solutions often include industry-leading IBM software and systems, other suppliers' products are also used if a client solution requires it. Approximately 60 percent of external Global Services segment revenue is annuity based, coming primarily from outsourcing and maintenance arrangements. The Global Services backlog provides a solid revenue base entering each year. Within Global Services, there are two reportable segments: Global Technology Services and Global Business Services.

        Global Technology Services (GTS) primarily provides IT infrastructure and business process services, creating business value for clients through unique technology and IP integrated services within its global delivery model.

        Global Financing facilitates clients' acquisition of IBM systems, software and services. Global Financing invests in financing assets, leverages with debt and manages the associated risks with the objective of generating consistently strong returns on equity. The primary focus on the company's offerings and clients mitigates many of the risks normally associated with a financing company. Global Financing has the benefit of both a deep knowledge of its client base and a clear insight into the products and services that are being financed. This combination allows Global Financing to effectively manage two of the major risks (credit and residual value) that are normally associated with financing.

Global Financing Capabilities

        Client Financing: lease and loan financing to end users and internal clients for terms generally between one and seven years. Internal financing is predominantly in support of Global Services' long-term client service contracts. Global Financing also factors a selected portion of the company's accounts receivable, primarily for cash management purposes. All internal financing arrangements are at arm's-length rates and are based upon market conditions.

        Commercial Financing: short-term inventory and accounts receivable financing to dealers and remarketers of IT products.

        Remanufacturing and Remarketing: as equipment is returned at the conclusion of a lease transaction, these assets are refurbished and sold or leased to new or existing clients both externally and internally. Externally remarketed equipment revenue represents sales or leases to clients and resellers. Internally remarketed equipment revenue primarily represents used equipment that is sold internally to Systems and Technology and Global Services. Systems and Technology may also sell the equipment that it purchases from Global Financing to external clients.

        IBM Research also focuses on differentiating IBM's services businesses, providing new capabilities and solutions. It has the world's largest mathematics department of any public company, enabling IBM to create unique analytic solutions and actively engage with clients on their toughest challenges.

        In 2012,2013, IBM was awarded more U.S. patents than any other company for the 20th21st consecutive year. IBM's 6,4786,809 patents awarded in 2012 included2013 represent a diverse range of inventions poised to enable significant innovations that will enable fundamental advancementsposition the company to compete and lead in analytics,strategic areas such as Watson, cloud computing and big data cybersecurity, cloud, mobile, social networkinganalytics. These inventions also will advance the new era of cognitive systems where machines will learn, reason and software defined environments, as well as industry solutions for retail, banking, healthcare, and transportation.interact with people in more natural ways. It was the most U.S. patents ever awarded to one company in a single year.

        The company continues to actively seek intellectual property protection for its innovations, while increasing emphasis on other initiatives designed to leverage its intellectual property leadership. Some of IBM's technological breakthroughs are used exclusively in IBM products, while others are licensed and may be used in either/both IBM products and/or the products of the licensee. While the company's various proprietary intellectual property rights are important to its success, IBM believes its business as a whole is not materially dependent on any particular patent or license, or any particular group of patents or licenses. IBM owns or is licensed under a number of patents, which vary in duration, relating to its products.

Enterprise Transformation

        A key element of the company's strategy has been focusedis becoming a Smarter Enterprise. The transformation to a Smarter Enterprise is built on becoming the premier globally integrated enterprise. The company hasfoundation of internal transformation undertaken in the recent past, where IBM standardized business processes, drove enterprisewide transformation governance, implemented a consistent set of processes and standards worldwide to reduce inefficiencies and improve collaboration. With its processes fully standardized, the company implemented a newglobal operating model, with work shared in global resource centers of excellence located where it made the most business sense. The company has shifted resources toward building client relationshipsinstrumented data, and employee skills, while positioning the company for new market opportunities. During this transformation, IBM pioneered this new operating model, changing from a classic "multinational," with smaller versions of the parent company replicated in countries around the world,connected employees to a global model with one set of processes, shared servicesdrive collaboration across geographic and broadly distributed decision making.functional boundaries.

        The company has now embarked on the next generationSmarter Enterprise is enabled through application of its transformation in which new capabilities and technologies like business analytics, social, mobile and cloud computing will drivetools, approaches and technologies. Analytics enable data-driven insights for faster, smarter decision making. Social tools encourage peer-to-peer interactions, and allow data to be shared within and outside IBM in a social way. Mobile technology allows workers to work seamlessly from anywhere. Cloud infrastructure and services enable application delivery. Collectively these enablers allow IBM to make decisions differently, create value differently and deliver value differently, thereby improving employee engagement and client experience and ultimately driving better business performance. The proven principles of the globally integrated enterprise will be applied to all of the company's spending to continue to drive additional productivity benefits in shared services, end-to-end process transformation and integrated operations. The company primarily reinvests the benefits of its enterprise transformation initiatives in remixing its spending profile and resources to theits higher growth, higher margin initiatives, such as business analytics, Smarter Planet and cloud computing, in addition to improving profitability.

Integrated Supply Chain

        IBM spends approximately $35 billion annually through itshas an extensive integrated supply chain, procuring materials and services globally. In addition, in 2012,2013, the company also managed approximately $20 billion in procurement spending for its clients through the Global Process Services organization. The supply, manufacturing and logistics and customer fulfillmentsales transaction support operations are integrated in one operating unit that has optimized inventories over time. Simplifying and streamlining internal processes has improved sales force productivity and operational effectiveness and efficiency. Continuous improvements to supplySupply chain resiliency againstenables IBM to reduce its risk during marketplace changes and risks have been particularly valuable in maintaining continuity during natural disasters and other disruptive events.changes.

        The company's continuing effortscompany continues to derive business value from its own globally integrated supply chain providesproviding a strategic advantage for the company to create value for clients. IBM leverages its supply chain expertise for clients through its supply chain business transformation outsourcing service to optimize and help operate clients' end-to-end supply chain processes, from procurement to logistics.

        Increasingly theThe company is usinghas expanded its use of analytics to measure, manage and fine tune its supply chain operations, which will help to reshape its operations and create value for clients. The goal is to continue to increase the use of analytics in the five major areas of supply chain: 1) Supply Chain Visibility, 2) Risk Management, 3) Customer Insight, 4) Cost Containment, and 5) Global Supply Chain and Sustainability.

COMPETITION

        The company is a globally-integrated enterprise, operating in more than 170175 countries. The company participates in a highly competitive environment, where its competitors vary by industry segment, and range from large multinational enterprises to smaller, more narrowly focused entities. Overall, across its business segments, the company recognizes hundreds of competitors worldwide.

        Across its business, the company's principal methods of competition are: technology innovation; performance; price; quality; brand; its broad range of capabilities, products and services; client relationships; the ability to deliver business value to clients; and, service and support. In order to maintain leadership, a corporation must continue to invest, innovate and integrate. The company has

been executing a strategy to transform its business, including shifting to higher value market segments and offerings and increasing its capabilities through organic investments and strategic acquisitions. As the company executes its strategy, it enters new markets, such as smarter planet and business analytics, which exposes the company to new competitors. Overall, the company is the leader or among the leaders in each of its business segments.

        A summary of the competitive environment for each business segment is included below:

Global Services:

        The services segments, GTS and GBS, operate in a highly competitive and continually evolving global market. GTS competes in strategic outsourcing, business process outsourcing, cloud services, and a wide range of technical and IT support services. GBS competes in consulting, system integration and application management services. The principal competitive factors in these business segments include: technical skills and capabilities, innovative service and product offerings, industry knowledge and experience, value and speed, price, client relationships, quality of sales and delivery, reliability, security and the availability of resources. The company's competitive advantages in the services business include its global reach and scale, global delivery model, best-of-breed process and industry skills, extensive technology expertise, services assets, an ability to deliver integrated solutions that can address clients' needs in any environment and a strong set of relationships with clients and strategic business partners worldwide. The company competes with broad based competitors including: Accenture, Amazon.com, Inc., Computer Sciences Corporation, Fujitsu and Hewlett-Packard Company (HP); India-based service providers; the consulting practices of public accounting firms; and many companies that primarily focus on local markets or niche service areas.

Software:

        The enterprise management software market is highly competitive, and increasingly technology companies are looking to implement software solutions that will improve business outcomes for their clients. The key competitive factors in this segment include: functionality, ease-of-use, scalability, open standards, total cost-of-ownership and business value. IBM's leadership in each of these areas, and the ability to deliver solutions that drive business results, provides it with competitive advantages. The company's software business includes middleware, solutions offerings and operating systems. The middleware portfolio is the broadest in the industry and covers both mainframe and distributed computing environments. The middleware portfolio also underpins IBM's solutions business and enhances the business value the company brings to clients. The solutions portfolio provides comprehensive business and industry- specific offerings to new types of IT decision makers, such as chief marketing and procurement officers, chief information security officers and chief financial officers. The depth and breadth of the company's software offerings, coupled with itsthe company's global sales and technical support infrastructure, differentiate the software business from its competitors. The company's research and development capabilities and intellectual property patent portfolio also contribute to this segment's leadership. The company's principal competitors in this segment include CA, Inc., Microsoft Corporation, and Oracle Corporation (Oracle). and SAP.

In addition, the company's research and development capabilities and intellectual property patent portfolio contribute significantly to this segment's leadership.

Global Financing:

        Global Financing provides client financing, commercial financing and participates in the remarketing of used equipment. The economic crisis of 2008 and 2009 drove an increase in credit spreads and a tightening supply of credit which have subsequently eased. However, going forward credit spreads may increase and the supply of credit may tighten based on worldwide economic conditions. Global Financing's access to capital and its ability to manage increased exposures provide a competitive advantage for the company. The key competitive factors include price, IT product expertise, client service, contract flexibility, ease of doing business, global capabilities and residual values. In client and commercial financing, Global Financing competes with three types of companies in providing financial services to IT customers: other captive financing entities of companies such as Cisco and HP and non-captive financing entities of companies such as General Electric Company and banks or financial institutions. In remarketing, the company competes with local and regional brokers plus original manufacturers in the fragmented worldwide used IT equipment market.

Item 1A. Risk Factors:

        Downturn in Economic Environment and Corporate ITClient Spending Budgets could impact the Company's Business: If overall demand for systems, software and services decreases, whether due to general economic conditions or a shift in corporateclient buying patterns, the company's revenue and profit could be impacted.

        The Company may not meet its Growth and Productivity Objectives under its Internal Business Transformation and Global Integration Initiatives: On an ongoing basis, IBM seeks to drive greater productivity, flexibility and cost savings by transforming and globally integrating its own business processes and functions to remain competitive and to enable scaling of resources and offerings in both emerging and more established markets. These various initiatives may not yield their intended gains in

quality, productivity and enablement of rapid scaling, which may impact the company's competitiveness and its ability to meet its growth and productivity objectives.

        Failure of Innovation Initiatives could impact the Long-Term Success of the Company: IBM has been moving away from certain segments of the IT industry and into areas in which it can differentiate itself through innovation and by leveraging its investments in R&D. If IBM is unable to continue its cutting-edge innovation in a highly competitive environment or is unable to commercialize such innovations or expand and scale them with sufficient speed, the company could fail in its ongoing

efforts to maintain and increase its market share and its profit margins. In addition, IBM has one of the strongest brand names in the world, and its brand and overall reputation could be negatively impacted by many factors, including if the company does not continue to be recognized for its industry-leading technology and solutions. If the company's brand image is tarnished by negative perceptions, our ability to attract and retain customers could be impacted.

        Risks from Investing in Growth Opportunities could impact the Company's Business: The company continues to invest significantly in strategic growth opportunities, including higher-value segments of enterprise computing, cloud computing, and new and emerging markets and countries, to drive revenue growth and market share gains. Client adoption rates and viable economic models are less certain in the high-value, highly competitive, and rapidly-growing segments, and new delivery models may unfavorably impact demand for our other products or services. In addition, as the company expands to capture emerging growth opportunities, it needs to rapidly secure the appropriate mix of trained, skilled and experienced personnel. In emerging growth countries, the developing nature presents potential political, social, legal and economic risks from evolving governmental policy, inadequate infrastructure, creditworthiness of customers and business partners, labor disruption and corruption, which could impact the company's ability to meet its growth objectives and to deliver to its clients around the world.

        IBM's Intellectual Property Portfolio may not prevent Competitive Offerings, and IBM may not be able to Obtain Necessary Licenses: The company's patents and other intellectual property may not prevent competitors from independently developing products and services similar to or duplicative to the company's, nor can there be any assurance that the resources invested by the company to protect its intellectual property will be sufficient or that the company's intellectual property portfolio will adequately deter misappropriation or improper use of the company's technology. In addition, the company may be the target of aggressive and opportunistic enforcement of patents by third parties, including non-practicing entities. Also, there can be no assurances that IBM will be able to obtain from third parties the licenses it needs in the future. The company's ability to protect its intellectual property could also be impacted by proposed changes to existing laws, legal principles and regulations governing the ownership and protection of patents and other intellectual property.

        Cybersecurity and Privacy Considerations could impact the Company's Business:The company's products, services, and systems may affect critical third party operations or involve the storage, processing and transmission of proprietary information and sensitive or confidential data, including valuable intellectual property and personal information of employees, customers and others. BreachesIn the current environment there are numerous and evolving risks to cybersecurity and privacy, including criminal hackers, state-sponsored intrusions, industrial espionage, employee malfeasance, and human or technological error. Computer hackers and others routinely attempt to breach the security of securitytechnology products, services, and systems, and those of customers, third-parties contractors and vendors, and some of those attempts may be successful. Such breaches could exposeresult in, for example, unauthorized access to, disclosure, modification, misuse, loss, or destruction of company, customer, or other third party data or systems, theft of sensitive or confidential data including personal information and intellectual property, system disruptions, and denial of service. In the event of such breaches, the company, its customers or othersother third parties could be exposed to risks of loss, including the misuse of information or systems, resulting inpotential liability, litigation, and potential liability for the company,regulatory action, as well as the loss of existing or potential customers, and damage to the company's brand and reputation.reputation, and other financial loss. In addition, the cost and operational consequences of responding

to breaches and implementing further data protectionremediation measures could be significant. Also,As these threats develop and grow, the company may also find it necessary to make significant further investments to protect data and infrastructure. As a global enterprise, the company could also be negatively impacted by existing and proposed laws and regulations, as well as government policies and practices related to cybersecurity, privacy and data protection. Additionally, cyber attacks or other catastrophic events resulting in disruptions to or failures in power, information technology, communication systems or other critical infrastructure could result in interruptions or delays to company, customer, or other third party operations or services, financial loss, potential liability, and damage to brand and reputation.

        The Company's Financial Results for Particular Periods are Difficult to Predict:IBM's revenues are affected by such factors as the introduction of new products and services, the length of the sales cycles and the seasonality of technology purchases. Moreover, the company's strategic growth areas involve new products, new customers, and new markets, all of which contribute to the difficulty of predicting the company's financial results. The company's financial results may also be impacted by the structure of products and services contracts and the nature of its customers' businesses; for example, certain of the company's services contracts with commercial customers in regulated industries are subject to periodic review by regulators with respect to controls and processes. As a result of the above-mentioned factors, the company's financial results are difficult to predict. Historically, the company has had lower revenue in the first quarter than in the immediately preceding fourth quarter. In addition, the high volume of products typically ordered at the end of each quarter, especially at the end of the fourth quarter, may affect IBM's ability to successfully ship all orders before the end of the quarter.

        Due to the Company's Global Presence, its Business and Operations could be impacted by Local Legal, Economic, Political and Health Conditions: The company is a globally integrated entity, operating in over 170175 countries worldwide and deriving more than sixty percent of its revenues from sales outside the United States. Changes in the laws or policies of the countries in which the company operates, or

inadequate enforcement of laws or policies, could affect the company's business and the company's overall results of operations. The company's results of operations also could be affected by economic and political changes in those countries and by macroeconomic changes, including recessions, inflation and currency fluctuations between the U.S. dollar and non-U.S. currencies. Further, as the company expands its customer base and the scope of its offerings, both within the U.S. and globally, it may be impacted by additional regulatory or other risks. In addition, any widespread outbreak of an illness, pandemic or other local or global health issue or uncertain political climates, international hostilities, natural disasters, or any terrorist activities, could adversely affect customer demand and the company's operations and its ability to source and deliver products and services to its customers.

        The Company could incur Substantial Costs for Environmental Matters: The company is subject to various federal, state, local and foreign laws and regulations concerning the discharge of materials into the environment or otherwise related to environmental protection, including the U.S. Superfund law. The company could incur substantial costs, including cleanup costs, fines and civil or criminal sanctions, as well as third-party claims for property damage or personal injury, if it were to violate or become liable under environmental laws and regulations. Compliance with environmental laws and regulations is not expected to have a material adverse effect on the company's financial position, results of operations and competitive position.

        Tax Matters could impact the Company's Results of Operations and Financial Condition: The company is subject to income taxes in both the United States and numerous foreign jurisdictions. IBM's provision for income taxes and cash tax liability in the future could be adversely affected by numerous factors including, but not limited to, income before taxes being lower than anticipated in countries with lower statutory tax rates and higher than anticipated in countries with higher statutory tax rates, changes in the valuation of deferred tax assets and liabilities, and changes in tax laws, regulations, accounting principles or interpretations thereof, which could adversely impact the company's results of operations and financial condition in future periods. In addition, IBM is subject to the continuous

examination of its income tax returns by the United States Internal Revenue Service and other tax authorities. The company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on the company's provision for income taxes and cash tax liability.

        The Company's Results of Operations and Financial Condition could be negatively impacted by its U.S. and non-U.S. Pension Plans: Adverse equity market conditions and volatility in the credit markets may have an unfavorable impact on the value of the company's pension trust assets and its future estimated pension liabilities. As a result, the company's financial results in any period could be negatively impacted. In addition, in a period of an extended financial market downturn, the company could be required to provide incremental pension plan funding with resulting liquidity risk which could negatively impact the company's financial flexibility. Further, the company's results of operations and financial results could be negatively impacted by premiums for mandatory pension insolvency insurance coverage outside the U.S. Premium increases can be significant due to the level of insolvencies of unrelated companies in the country at issue. Currently, Canada, Germany, Luxembourg and the United Kingdom require that these premiums be paid directly by the company and not out of plan assets, which could negatively impact the company's earnings. IBM's 20122013 Annual Report to Stockholders includes information about potential impacts from pension funding and the use of certain assumptions regarding pension matters.

        Ineffective Internal Controls could impact the Company's Business and Operating Results:The company's internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility of human error, the circumvention or overriding of controls, or fraud. Even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of financial statements. If the company fails to maintain the adequacy of its internal controls, including any failure to implement required new or improved controls,

or if the company experiences difficulties in their implementation, the company's business and operating results could be harmed and the company could fail to meet its financial reporting obligations.

        The Company's Use of Accounting Estimates involves Judgment and could impact the Company's Financial Results: The application of generally accepted accounting principles requires the company to make estimates and assumptions about certain items and future events that directly affect its reported financial condition. The company's most critical accounting estimates are described in the Management Discussion in IBM's 20122013 Annual Report to Stockholders, under "Critical Accounting Estimates." In addition, as discussed in note M, "Contingencies and Commitments," in IBM's 20122013 Annual Report to Stockholders, the company makes certain estimates including decisions related to legal proceedings and reserves. These estimates and assumptions involve the use of judgment. As a result, actual financial results may differ.

        The Company Depends on Skilled Personnel and could be impacted by the loss of Critical Skills: Much of the future success of the company depends on the continued service, availability and integrity of skilled personnel, including technical, marketing and staff resources. ExperiencedSkilled and experienced personnel in the information technology industryareas where the company competes are in high demand, and competition for their talents is intense. Changing demographics and labor work force trends may result in a loss of knowledge and skills as experienced workers leave the company. In addition, as global opportunities and industry demand shifts, realignment, training and scaling of skilled resources may not be sufficiently rapid. Further, many of IBM's key personnel receive a total compensation package that includes equity awards. New regulations, volatility in the stock market and other factors could diminish the company's use, and the value, of the company's equity awards, putting the company at a competitive disadvantage or forcing the company to use more cash compensation.

        The Company's Business could be impacted by its Relationships with Critical Suppliers:IBM's business employs a wide variety of components, supplies, services and raw materials from a substantial number of suppliers around the world. Certain of the company's businesses rely on single or a limited number of suppliers. Changes in the financialbusiness condition (financial or business conditionotherwise) of these suppliers could subject the company to losses and affect its ability to bring products to market. Further, the failure of the company's suppliers to deliver components, supplies, services and raw materials in sufficient quantities, and in a timely manner, and in compliance with all applicable laws and regulations could adversely affect the company's business. In addition, any defective components, supplies or materials, or inadequate services received from suppliers could reduce the reliability of the company's products and services and harm the company's reputation.

        The Company could be impacted by its Business with Government Clients:The company's customers include numerous governmental entities within and outside the U.S., including the U.S. Federal Government and state and local entities. Some of the company's agreements with these customers may be subject to periodic funding approval. Funding reductions or delays could adversely impact public sector demand for our products and services. Also, some agreements may contain provisions allowing the customer to terminate without cause and providing for higher liability limits for certain losses. In addition, the company could be suspended or debarred as a governmental contractor and could incur civil and criminal fines and penalties, which could negatively impact the company's results of operations and financial results.

        The Company is exposed to Currency and Customer Financing Risks that could impact its Revenue and Business:The company derives a significant percentage of its revenues and costs from its affiliates operating in local currency environments, and those results are affected by changes in the relative values of non-U.S. currencies and the U.S. dollar. Further, inherent in the company's customer financing business are risks related to the concentration of credit, client creditworthiness, interest rate and currency fluctuations on the associated debt and liabilities, the determination of residual values and the financing of other than traditional IT assets. The company employs a number of strategies to manage these risks, including the use of derivative financial instruments; derivativesinstruments, which involve the risk of non-performance by the counterparty. In addition, there can be no assurance that the company's efforts to manage its currency and customer financing risks will be successful.

        The Company's Financial Performance could be impacted by Changes in Market Liquidity Conditions and by Customer Credit Risk on Receivables: The company's financial performance is exposed to a wide variety of industry sector dynamics worldwide. The company's earnings and cash flows, as well as its access to funding, could be negatively impacted by changes in market liquidity conditions. IBM's 20122013 Annual Report to Stockholders includes information about the company's liquidity position. The company's client base includes many worldwide enterprises, from small and medium businesses to the world's largest organizations and governments, with a significant portion of the company's revenue coming from global clients across many sectors. Most of the company's sales are on an open credit basis, and the company performs ongoing credit evaluations of its clients' financial conditions. If the company becomes aware of information related to the creditworthiness of a major customer, or, if future actual default rates on receivables in general differ from those currently anticipated, the company may have to adjust its allowance for credit losses, which could affect the company's consolidated net income in the period the adjustments are made.

        The Company's Reliance on Third Party Distribution Channels could impact its Business:The company offers its products directly and through a variety of third party distributors and resellers. Changes in the financialbusiness condition (financial or business conditionotherwise) of these distributors and resellers could subject the company to losses and affect its ability to bring its products to market. As the company moves into new areas, distributors and resellers may be unable to keep up with changes in technology and offerings, and the company may be unable to recruit and enable appropriate partners to achieve growth objectives. In addition, the failure of third party distributors and resellers to comply with all

applicable laws and regulations may prevent the company from working with them and could subject the company to losses and affect its ability to bring products to market.

        Risks to the Company from Acquisitions, Alliances and AlliancesDispositions include Integration Challenges, Failure to Achieve Objectives, and the Assumption of Liabilities:The company has made and expects to continue to make acquisitions, or enter into alliances.alliances and dispositions. Acquisitions and alliances present significant challenges and risks relating to the integration of the business into the company, and there can be no assurances that the company will manage acquisitions and alliances successfully.successfully or that strategic acquisition opportunities will be available to the company on acceptable terms or at all. The related risks include the company failing to achieve strategic objectives and anticipated revenue improvements and cost savings, as well as the failure to retain key personnel of the acquired business and the assumption of liabilities related to litigation or other legal proceedings involving the acquired business. From time to time, the company disposes or attempts to dispose of assets that are no longer central to its strategic objectives. Any such disposition or attempted disposition is subject to risks, including risks related to the terms and timing of such disposition, risks related to obtaining necessary governmental or regulatory approvals and risks related to retained liabilities not subject to the company's control.

The Company is Subject to Legal Proceedings Risks: As a company with a substantial employee population and with clients in more than 175 countries, IBM is involved, either as plaintiff or defendant, in a variety of ongoing claims, demands, suits, investigations, tax matters and proceedings that arise from time to time in the ordinary course of its business. The risks associated with such legal proceedings are described in more detail in note M, "Contingencies and Commitments," in IBM's 2013 Annual Report to Stockholders. The company believes it has adopted appropriate risk management and compliance programs. Legal and compliance risks, however, will continue to exist and additional legal proceedings and other contingencies, the outcome of which cannot be predicted with certainty, may arise from time to time.

        Risk Factors Related to IBM Securities: The company and its subsidiaries issue debt securities in the worldwide capital markets from time to time, with a variety of different maturities and in different currencies. The value of the company's debt securities fluctuates based on many factors, including the methods employed for calculating principal and interest, the maturity of the securities, the aggregate principal amount of securities outstanding, the redemption features for the securities, the level, direction and volatility of interest rates, changes in exchange rates, exchange controls, governmental and stock exchange regulations and other factors over which the company has little or no control. The company's ability to pay interest and repay the principal for its debt securities is dependent upon its ability to manage its business operations, as well as the other risks described under this Item 1A. entitled "Risk Factors." There can be no assurance that the company will be able to manage any of these risks successfully.

        The company also issues its common stock from time to time in connection with various compensation plans, contributions to its pension plan and certain acquisitions. The market price of IBM common stock is subject to significant volatility, due to other factors described under this Item 1A. entitled "Risk Factors," as well as economic and geopolitical conditions generally, trading volumes, speculation by the press or investment community about the company's financial condition, and other factors, many of which are beyond the company's control. Since the market price of IBM's common stock fluctuates significantly, stockholders may not be able to sell the company's stock at attractive prices.

        In addition, changes by any rating agency to the company's outlook or credit ratings can negatively impact the value and liquidity of both the company's debt and equity securities. The company does not

make a market in either its debt or equity securities and cannot provide any assurances with respect to the liquidity or value of such securities.

Equity Compensation Plan Information

        The material features of each equity compensation plan under which equity securities are authorized for issuance that was adopted without stockholder approval are described below:

2001 LONG-TERM PERFORMANCE PLAN

        The 2001 Long-Term Performance Plan (the "2001 Plan") has been used to fund awards for employees other than senior executives of the company. Awards for senior executives of the company

have been and will continue to be funded from the stockholder-approved 1999 Long-Term Performance Plan (the "1999 Plan"); the 1999 Plan is also used to fund awards for employees other than senior executives. Otherwise, the provisions of the 2001 Plan are identical to the 1999 Plan, including the type of awards that may be granted under the plan (stock options, restricted stock and unit awards and long-term performance incentive awards).

        The 2001 Plan is administered by the Executive Compensation and Management Resources Committee of the Board of Directors, and that Committee may delegate to officers of the company certain of its duties, powers and authority. Payment of awards may be made in the form of cash, stock or combinations thereof and may be deferred with Committee approval. Awards are not transferable or assignable except (i) by law, will or the laws of descent and distribution, (ii) as a result of the disability of the recipient, or (iii) with the approval of the Committee.

        If the employment of a participant terminates, other than as a result of the death or disability of a participant, all unexercised, deferred and unpaid Awards shall be canceled immediately, unless the Award Agreement provides otherwise. In the event of the death of a participant or in the event a participant is deemed by the company to be disabled and eligible for benefits under the terms of the IBM Long-Term Disability Plan (or any successor plan or similar plan of another employer), the participant's estate, beneficiaries or representative, as the case may be, shall have the rights and duties of the participant under the applicable Award Agreement. In addition, unless the Award Agreement specifies otherwise, the Committee may cancel, rescind, suspend, withhold or otherwise limit or restrict any unexpired, unpaid, or deferred Awards at any time if the participant is not in compliance with all applicable provisions of the Award Agreement and the Plan. In addition, Awards may be cancelled if the participant engages in any conduct or act determined to be injurious, detrimental or prejudicial to any interest of the Company.

PWCC ACQUISITION LONG-TERM PERFORMANCE PLAN

        The IBM PWCC Acquisition Long-Term Performance Plan (the "PWCC Plan") was adopted by the Board of Directors in connection with the company's acquisition of PricewaterhouseCoopers Consulting ("PwCC") from PricewaterhouseCoopers LLP, as announced on October 1, 2002. The PWCC Plan has been and will continue to be used solely to fund awards for employees of PwCC who have come over to the company as a result of the acquisition. Awards for senior executives of the company will not be funded from the PWCC Plan. The terms and conditions of the PWCC Plan are substantively identical to the terms and conditions of the 2001 Plan, described above.

IBM DEFERRED COMPENSATION AND EQUITY AWARD PLAN

        The IBM Deferred Compensation and Equity Award Plan (the "DCEAP") was adopted in 1993. Under the DCEAP, non-management directors receive Promised Fee Shares in connection with deferred annual retainer payments. Each Promised Fee Share is equal in value to one share of the company's common stock. Upon a director's retirement or other completion of service as a director, all amounts deferred into Promised Fee Shares are payable in either cash and/or shares of the company's stock at the director's election. (For additional information about the DCEAP, see "General Information—2012 Director Compensation Narrative" in IBM's definitive Proxy Statement to be filed with the Securities and Exchange Commission and delivered to stockholders in connection with the Annual Meeting of Stockholders to be held April 30, 2013).
