BUSINESSOur BusinessWe develop, market, license, and support enterprise software applications that help organizations transform the way they engage with their customers and processand complete work across their enterprise. We license our no-code Pega Platform™ for rapid application development to clients that wish to build and extend theirown business applications. Our cloud-architected portfolio of customer engagement and digital process automation applications leverages artificial intelligence(“AI”), case management, and robotic automation technology, built on our unified no-code Pega Platform, empowering businesses to quickly design, extend, andscale their enterprise applications to meet strategic business needs.To grow our business, we intend to:•grow market share by developing and delivering market-leading applications for marketing, sales, service, and operations that can work togetherseamlessly with maximum differentiation and minimal customization;•execute new-market growth initiatives, further expanding sales coverage within the Global 3000; and•continue to scale our digital platform and invest in awareness marketing to support the way today’s clients want to buy products and services.Whether we are successful depends, in part, on our ability to:•successfully execute our marketing and sales strategies;•appropriately manage our expenses as we grow our organization;•effectively develop new products and enhance our existing products; and•successfully incorporate acquired technologies into our applications and unified Pega Platform.Our ProductsPega Infinity™, the latest version of our platform, helps connect enterprises to their customers in real-time across channels, streamline business operations, andadapt to meet changing requirements.Our applications and platform intersect with and encompass several software markets, including:•Customer Engagement, including Customer Relationship Management (“CRM”);•Digital Process Automation (“DPA”), including Business Process Management (“BPM”);5•Robotic Process Automation (“RPA”);•Business Rules Management Systems (“BRMS”);•Dynamic Case Management (“DCM”);•Decision Management, including predictive and adaptive analytics;•No-code and low-code application development platforms, including Mobile Application Development Platforms (“MADP”); and•Vertical-Specific Software (“VSS”) market of industry solutions and packaged applications.Customer engagementOur omni-channel customer engagement applications are designed to maximize the lifetime value of customers and help reduce the costs of serving customerswhile ensuring a consistent, unified, and personalized customer experience. At the center of our customer engagement applications is the Pega Customer DecisionHub™, our real-time AI engine, which can predict a customer’s behavior and recommend the “next-best-action” to take across channels in real-time.•Pega Marketing ™ is designed to enable enterprises to improve customer acquisition and experiences across inbound, outbound, and paid media channels.It incorporates AI in the form of predictive and machine-learning analytics, as well as business rules, and executes these decisions in real-time to evaluatethe context of each customer interaction and dynamically deliver the most relevant action, offer, content, and channel.•Pega Sales Automation ™ automates and manages the entire sales process, from prospecting to product fulfillment. It allows enterprises to capture bestpractices, and leverages AI to guide sales teams through the sales and customer onboarding processes.•Pega Customer Service ™ is designed to anticipate customer needs, connect customers to the right people and systems, and automate or intelligently guidecustomer interactions, to rapidly and continuously evolve the customer service experience and to allow enterprises to deliver consistent interactions acrosschannels and improve employee productivity. The application consists of a contact center desktop, case management for customer service, chat,knowledge management, mobile field service, omni-channel self-service, AI-powered virtual assistants, and industry-specific processes and data models.Digital process automationWe offer industry-specific software applications built on the Pega Platform. These applications provide businesses with robust capabilities to automate industry-specific business processes. As they are built on the Pega Platform, these applications deliver flexibility beyond traditional, “off-the-shelf” products. Ourapplications allow our clients to offer differentiated service and value to their customers. The Pega Platform empowers organizations to implement new processesquickly, refine customer experiences, bring new offerings to market, and provide customized or specialized automated processing.Our CapabilitiesWe drive better business outcomes in two ways:•Making decisions: delivering real-time customer engagement, powered by real-time, omni-channel AI•Getting work done: making customer and employee-facing processes more efficient through end-to-end automation and roboticsReal-time, omni-channel AIAI has been around for many years, in many forms, yet only in the past decade have businesses started using its practical applications, fueled by the newabundance of data to power decisions and ever-increasing customer expectations. Our customer engagement and other applications built on the Pega Platformleverage predictive and adaptive analytics to deliver more personalized customer experiences and maximize business objectives. The Pega Customer DecisionHub, a centralized, always-on “brain”, unleashes the power of predictive analytics, machine learning, and real-time decisioning across our clients’ data, systems,and touchpoints - orchestrating engagement across customer interaction channels.End-to-end robotic automationWe bring together both human-assisted robotic desktop automation and unattended robotic process automation with our unified DPA and case managementcapabilities. This gives our platform and applications the ability to automate both customer-facing and back-office operational processes from “end-to-end”,connecting across organizational and system silos to seamlessly connect customers and employees to successful customer experiences.Journey-centric rapid deliveryOur customer engagement and DPA solutions are designed to improve targeted customer outcomes, quickly and with out-of-the-box functionality that connectsenterprise data and systems to customer experience channels. From there, organizations can scale, one customer experience at a time, to realize greater value whiledelivering increasingly consistent and personalized customer experiences.6Software That Writes Your Software ® Our approach bypasses the error-prone and time-consuming process of manually translating requirements into code. Users design software in no-code visualmodels that reflect the needs of the business. The software application is created and optimized automatically and directly from the model, helping to close thecostly gap between vision and execution. Changes to the code are made by altering the model, and application documentation is generated directly from the model.The Pega Platform is standards-based and can leverage a client’s existing technology to create new business applications that cross technology silos and bridge thefront and back-office.Unified future-proof platformWe offer a unified DPA platform, combining robotics, process automation, and case management together in a unified architecture. We build in powerful decisionanalytics, designed to allow our clients to automate any process while working faster and smarter. Our no-code architecture is designed to empower organizationsto scale across all dimensions of their business, including product lines, departments, and geographies, by reusing components and avoiding the traditional methodof deploying multiple customer engagement and DPA instances that lead to even more silos and disjointed customer experiences.Cloud choicePega Cloud ® allows clients to develop, test, and deploy, on an accelerated basis, our applications and the Pega Platform using a secure, flexible internet-basedinfrastructure, minimizing cost while focusing on core revenue generating competencies.The Pega Platform and applications are deployable on other cloud architectures, including client or partner-managed clouds. This cloud choice gives our clients theability to select, and change as needed, the best cloud architecture for the security, data access, speed-to-market, and budget requirements of each application theydeploy.Our Services and SupportWe offer services and support through our Global Client Success, Global Service Assurance, Global Client Support, and Pega Academy ™ groups.

Our customer engagement, clinical, and pharmacovigilance applications are designed to deliver customerengagement, safety and risk management, and regulatory transparency.CompetitionThe markets for our offerings are intensely competitive, rapidly changing, and highly fragmented, as current competitors expand their product offerings and newcompanies enter the market. See "Item 1A. Risk Factors" of this Annual Report for additional information.We encounter competition from:•Customer engagement, including CRM application vendors;•DPA, including BPM vendors, no-code and low-code application development platforms, and service-oriented architecture middleware vendors;•Case management vendors;•Decision management, data science and AI vendors, as well as vendors of solutions that leverage decision making and data science in managing customerrelationships and marketing;•Robotic automation and workforce intelligence software providers;•Companies that provide application-specific software for financial services, healthcare, insurance, and other specific markets;•Mobile application platform vendors;8•Co-browsing software providers;•Social listening, text analytics, and natural language processing vendors;•Professional service organizations that develop their own products or create custom software in conjunction with rendering consulting services; and•Clients’ in-house information technology departments, which may seek to modify their existing systems or develop their own proprietary systems.Competitors vary in size, scope, and breadth of the products and services they offer and include some of the largest companies in the world, such asSalesforce.com, Microsoft Corporation, Oracle Corporation, SAP SE, and International Business Machines Corporation (“IBM”).We have been most successful competing for clients whose businesses are characterized by a high degree of change, complexity, or regulation. We believe theprincipal competitive factors within our market include:•product adaptability, scalability, functionality, and performance;•proven success in delivering cost-savings and efficiency improvements;•proven success in enabling improved customer interactions;•ease-of-use for developers, business units, and end-users;•timely development and introduction of new products and product enhancements;•establishment of a significant base of reference clients;•ability to integrate with other products and technologies;•customer service and support;•product price;•vendor reputation; and•relationships with systems integrators.We believe we are competitively differentiated as our unified Pega Platform is designed to allow client business and IT staff, using a single, intuitive user interface,to build and evolve enterprise applications in a fraction of the time it would take with disjointed architectures and tools offered by our competitors. In addition, ourapplications, built on the Pega Platform, provide the same level of flexibility and ability to adapt to our clients’ needs as our Pega Platform. We believe wecompete favorably due to our expertise in our target industries and our long-standing client relationships. We believe we compete less favorably on some of theabove factors against our larger competitors, many of which have greater sales, marketing, and financial resources, more extensive geographical presence, andgreater name recognition than we do. In addition, we may be at a competitive disadvantage against our larger competitors with respect to our ability to provideexpertise outside our target industries.Intellectual PropertyWe rely primarily on a combination of copyright, patent, trademark, and trade secrets laws, as well as confidentiality and intellectual property agreements toprotect our proprietary rights. We have obtained patents relating to our system architecture and products in strategic global markets. We enter into confidentiality,intellectual property ownership, and license agreements with our employees, partners, clients, and other third parties. We also control access to and ownership ofsoftware, services, documentation, and other proprietary information to protect our proprietary rights.Sales and MarketingWe sell our software and services primarily through a direct sales force. In addition, strategic partnerships with management consulting firms and major systemsintegrators are important to our sales efforts, because they influence buying decisions, help us identify sales opportunities, and complement our software andservices with their domain expertise and consulting capabilities. We also partner with technology providers and application developers.To support our sales efforts, we conduct a broad range of marketing programs, including awareness advertising, client and industry-targeted solution campaigns,trade shows, including our PegaWorld ® user conference, solution seminars and webinars, industry analyst and press relations, web and digital marketing,community development, social media presence, and other direct and indirect marketing efforts. Our consulting employees, business partners, and other thirdparties also conduct joint and separate marketing campaigns that generate sales leads for us.Research and DevelopmentOur research and development organization is responsible for product architecture, core technology development, product testing, and quality9assurance. Our product development priority is to continue expanding the capabilities of our technology. We intend to maintain and extend the support of ourexisting applications, and we may choose to invest in additional strategic applications which incorporate the latest business innovations. We also intend to maintainand extend the support of popular hardware platforms, operating systems, databases, and connectivity options to facilitate easy and rapid deployment in diverse ITinfrastructures. Our goal with all products is to enhance product capabilities, ease of implementation, long-term flexibility, and the ability to provide improvedclient service.EmployeesAs of January 31, 2019 , we had 4,650 employees worldwide, of which 1,919 were based in North America, 960 were based in Europe, and 1,771 were based inAsia-Pacific.BacklogAs of December 31, 2018 , we expected to recognize $631 million in revenue in future periods from backlog on existing contracts. We must fulfill certainconditions related to these agreements prior to recognizing revenue, and there can be no assurance when, if ever, we will be able to satisfy all such conditions.See "Remaining Performance Obligations" in Item 7 of this Annual Report for additional information.Corporate InformationPegasystems Inc. was incorporated in Massachusetts in 1983.

RISK FACTORSThe risks and uncertainties described below are not the only ones we face. Other events that we do not currently anticipate or that we currently deem immaterialmay also affect our results of operations, cash flows, and financial condition.Risks Related to Our Business and IndustryWe may not be able to achieve the key elements of our strategy and grow our business as anticipated.We currently intend to grow our business by pursuing strategic initiatives. Key elements of our strategy include growing our market share by developing anddelivering robust applications that can work together seamlessly with maximum differentiation and minimal customization, offering versatility in our PegaPlatform and application deployment and licensing options to meet the specific needs of our clients, growing our network of partner alliances, and developing thetalent and organizational structure capable of supporting our revenue and earnings growth targets. We may not be able to achieve one or more of our keyinitiatives. Our success depends on our ability to appropriately manage our expenses as we grow our organization, successfully execute our marketing and salesstrategies, successfully incorporate acquired technologies into our unified Pega Platform and develop new products or product enhancements. If we are not able toexecute on these actions, our business may not grow as we anticipated, and our operating results and financial condition could be adversely affected.We depend on key personnel and must be able to attract and retain qualified personnel in the future.Our business is dependent on key, highly skilled technical, managerial, consulting, sales, and marketing personnel, including our Chief Executive Officer who isalso our founder and majority stockholder. The loss of key personnel could be disruptive to our operations and adversely affect financial performance. We do nothave any significant key-person life insurance on any officers or employees and do not plan to obtain any. Our success will depend in large part on the ability toattract and retain qualified personnel, and rapidly replace and develop new management. The number of potential employees who have the extensive knowledgeneeded to develop, sell, and maintain our offerings is limited, and competition for their services is intense, and there can be no assurance that we will be able toattract and retain such personnel. If we are unable to do so, our business, operating results, and financial condition could be materially adversely affected.10The timing of our license and cloud revenue is difficult to predict accurately, which may cause our operating results to vary considerably.A change in the size or volume of license and cloud arrangements, or a change in the mix between perpetual licenses, term licenses, and cloud arrangements cancause our revenues and cash flows to fluctuate materially between periods. Should a client choose to enter into a cloud arrangement revenue and cash flows aretypically recognized and received over the service period of the cloud arrangement. In contrast with a perpetual or term license the revenue is typically recognizedupfront when the license rights become effective .Factors which may influence the predictability of our license and cloud revenue include:•changes in clients’ budgets and decision-making processes that could affect both the timing and size of transactions;•deferral of license revenue to future periods due to the timing of the execution of an agreement or our ability to deliver the products or services;•changes in our business model; and/or•our ability to execute on our marketing and sales strategies.We budget for our selling and marketing, product development, and other expenses based upon anticipated future bookings and revenue. If the timing or amount ofrevenue fails to meet our expectations in a given period, our financial performance is likely to be adversely affected because only a small portion of our expensesvary with revenue. Other factors which may cause our operating results to vary considerably include changes in foreign currency exchange rates, income taxeffects, and the impact of new accounting pronouncements.As a result, period-to-period comparisons of our operating results are not necessarily meaningful and should not be relied upon to predict future performance. If ourrevenues and operating results do not meet the expectations of our investors or securities analysts or fall below guidance we may provide to the market, or due toother factors discussed elsewhere in this section, the price of our common stock may decline.The number of license and cloud arrangements has been increasing, and we may not be able to sustain this growth unless our partners and we can providesufficient high-quality consulting, training, and maintenance resources to enable our clients to realize significant business value from our software.Our clients typically request consulting and training to assist them in implementing our license and cloud offerings. Our clients also typically purchasemaintenance on our perpetual and term licenses. As a result, an increase in the number of license and cloud arrangements is likely to increase demand forconsulting, training, and maintenance related to our offerings. Given that the number of our license and cloud arrangements has been increasing, we will need toprovide our clients with more consulting, training, and maintenance to enable them to realize significant business value from our software. We have beenincreasing our partner and client enablement through training to create an expanded ecosystem of people that are skilled in the implementation of our products.However, if we and our partners are unable to provide sufficient high-quality consulting, training, or maintenance resources to our clients, our clients may notrealize sufficient business value from our offerings to justify follow-on sales, which could impact our future financial performance. In addition, the investmentsrequired to meet the increased demand for our consulting services could strain our ability to deliver our consulting engagements at desired levels of profitability,thereby impacting our overall profitability and financial results.We may not be able to maintain our retention rate for cloud clients.In recent periods, an increasing percentage of our revenue has been derived from our cloud offerings. Our clients have no obligation to renew their cloudsubscriptions, although historically most have elected to do so. If our retention rate for those clients were to decrease, our business, operating results, and financialcondition could be materially and adversely affected.We are investing heavily in sales and marketing, research and development, and support resources in anticipation of continued growth in license and cloudarrangements, and we may experience decreased profitability or losses if we do not continue to increase the value of our license and cloud arrangements tobalance our growth in expenses.We have been expanding our sales and marketing capacity to meet increasing demand for our software and to broaden our market coverage by hiring additionalsales and marketing personnel. We anticipate that we will need to provide our clients with more maintenance support because of this increase in demand and havebeen hiring additional personnel in this area. We continue to invest significantly in research and development to expand and improve the Pega Platform andapplications. These investments have resulted in increased fixed costs that do not vary with the level of revenue. If the increased demand for our offerings does notcontinue, we could experience decreased profitability or losses because of these increased fixed costs. Conversely, if we are unable to hire sales and marketingpersonnel to meet future demand or research and development personnel to enhance our current products or develop new products, we may not be able to achieveour sales and profitability targets .11We face risks from operations and clients based outside of the U.S.We market our products and services to clients based outside of the U.S., which represent an average of 44% of our total revenue over the last three fiscal years.We have established offices in the Americas, Europe, Asia, and Australia. We believe that growth will necessitate expanded international operations, resulting inincreased managerial attention and costs. We anticipate hiring additional personnel to accommodate increased international market demand, and we may also enterinto agreements with local distributors, representatives, or resellers. If we are unable to do one or more of these things in a timely and effective manner, the growth,if any, of our international operations may be restricted, and our business, operating results, and financial condition could be materially and adversely affected. Additional risks inherent in our international business activities generally include:•laws and business practices favoring local competitors;•compliance with multiple, conflicting, and changing governmental laws and regulations, including employment, tax, privacy and data privacy andprotection, and increased tariffs and other trade barriers;•the costs of localizing offerings for local markets, including translation into foreign languages and associated expenses;•longer payment cycles and credit and collectability risk on our foreign trade receivables;•economic and political uncertainty around the world, such as the U.K.’s referendum in which voters approved an exit from the European Union (EU),commonly referred to as “Brexit”;•difficulties in enforcing contractual and intellectual property rights;•heightened fraud and bribery risks;•treatment of revenue from international sources and changes to tax codes, including being subject to foreign tax laws, being liable for paying withholdingincome or other taxes in foreign jurisdictions, and other potentially adverse tax consequences (including restrictions on repatriating earnings and the threatof “double taxation”);•management of our international operations, including increased accounting, internal control, and compliance expenses;•heightened risks of political and economic instability; and•foreign currency exchange rate fluctuations and controls.There can be no assurance that one or more of these factors will not have a material adverse effect on our international operations, and, consequently, on ourbusiness, operating results, and financial condition.We rely on certain third-party relationships.We have a number of relationships with third parties that are significant to our sales, marketing, support, and product development efforts, including hostingfacilities for our cloud offering. We rely on software and hardware vendors, large system integrators, and technology consulting firms to supply marketing andsales opportunities for our direct sales force and to strengthen our products using industry-standard tools and utilities. We also have relationships with third partiesthat distribute our products. There can be no assurance that these companies, many of which have far greater financial and marketing resources than we do, will notdevelop or market offerings that compete with ours in the future or will not otherwise end or limit their relationships with us. Further, the use of third-party hostingfacilities requires us to rely on the functionality and availability of the third parties’ services, as well as their data security, which despite our due diligence, may beor become inadequate.We are exposed to fluctuations in currency exchange rates that could negatively impact our financial results and cash flows.Because a significant portion of our business is conducted outside the U.S., we face exposure to adverse movements in foreign currency exchange rates. Ourinternational sales are usually denominated in foreign currencies. The operating expenses of our foreign operations are also primarily denominated in foreigncurrencies, which partially offset our foreign currency exposure on our international sales. Our results of operations and cash flows are subject to fluctuations dueto changes in foreign currency exchange rates, particularly changes in the U.S. dollar, the Euro, and the Australian dollar relative to the British Pound. Theseexposures may change over time as business practices evolve.We have used in the past, but do not currently use foreign currency forward contracts to hedge our exposure to changes in foreign currency exchange ratesassociated with our foreign currency denominated cash, accounts receivable, and intercompany receivables and payables held by our U.S. parent company and itsU.K. subsidiary. We may enter into hedging contracts again in the future if we believe it is appropriate. Our realized gain or loss with respect to foreign currency fluctuations will generally depend on the size and type of cross-currency exposures that we enter into, thecurrency exchange rates associated with these exposures and changes in those rates, whether we have12entered into forward contracts to offset these exposures, and other factors. All of these factors could materially impact our operating results, financial condition,and cash flows.Our consulting revenue is significantly dependent upon our consulting personnel implementing new license and cloud arrangements .We derive a substantial portion of our consulting revenue from implementations of new licenses and cloud arrangements managed by our consulting personnel andconsulting for partner and client-led implementation efforts. Our strategy is to support and encourage partner-led and client-led implementations to increase thebreadth, capability, and depth of market capacity to deliver implementation services to our clients. Accordingly, if our consulting personnel’s involvement in futureimplementations decreases, this could adversely affect our consulting revenue.We frequently enter into a series of license or cloud arrangements that are each focused on a specific purpose or area of operations. If we are not successful inobtaining follow-on business from these clients, our financial performance could be adversely affected.Once a client has realized the value of our software, we work with the client to identify opportunities for follow-on sales. However, we may not be successful indemonstrating this value for a number of reasons, including the performance of our products, the quality of the services and support provided by us and ourpartners, or external factors. Also, some of our smaller clients may have limited additional sales opportunities available. We may not obtain follow-on sales, or thefollow-on sales may be delayed, and our future revenue could be limited. This could lower the total value of all transactions and adversely affect our financialperformance.We will need to acquire or develop new products, evolve existing ones, address any defects or errors, and adapt to technology changes.Technical developments, client requirements, programming languages, and industry standards change frequently in the markets in which we operate. As a result,our success will depend upon our ability to enhance current products, address any product defects or errors, acquire, or develop and introduce new products thatmeet client needs, keep pace with technology changes, respond to competitive products, and achieve market acceptance. Product development requires substantialinvestments for research, refinement, and testing. We may not have sufficient resources to make necessary product development investments. We may experiencetechnical or other difficulties that will delay or prevent the successful development, introduction, or implementation of new or enhanced products. We may alsoexperience technical or other difficulties in the integration of acquired technologies into our existing platform and applications. Inability to introduce or implementnew or enhanced products in a timely manner could result in loss of market share if competitors are able to provide solutions to meet client needs before we do,give rise to unanticipated expenses related to further development or modification of acquired technologies, and adversely affect future financial performance.The market for our offerings is intensely and increasingly competitive, rapidly changing, and highly fragmented .We compete in the CRM, including marketing, sales, and customer service, DPA, including BPM, case management, decision management, robotic automation,co-browsing, social engagement, and mobile application development platform software markets, as well as in markets for the vertical applications we provide(e.g. Pega KYC™ for Financial Services, Pega Underwriting™ for Insurance). These markets are intensely competitive, rapidly changing, and highly fragmented,as current competitors expand their product offerings and new companies enter the market.We encounter significant competition from other technology vendors, as well as clients’ internal information systems departments, that seek to modify theirexisting systems or develop their own proprietary systems, and professional service organizations that develop their own products or create custom software inconjunction with rendering consulting services. Competition for market share and pressure to reduce prices and make sales concessions are likely to increase.Many of our competitors, such as IBM, Oracle Corporation, Microsoft Corporation, SAP SE, and Salesforce.com, have far greater resources than we do and maybe able to respond more quickly and efficiently to new or emerging technologies, programming languages, or standards, or to changes in client requirements orpreferences. Competitors may also be able to devote greater managerial and financial resources to develop, promote, and distribute products and to provide relatedconsulting and training services. There can be no assurance that we will be able to compete successfully against current or future competitors or that thecompetitive pressures faced by us will not materially adversely affect our business, operating results, and financial condition. See "Competition" in Item 1 of thisAnnual Report for additional information.The continued uncertainties in the global economy may negatively impact our sales to, and the collection of receivables from, our clients.Our sales to, and our collection of receivables from, our clients may be impacted by adverse changes in global economic conditions. The U.S. and other keyinternational economies have experienced cyclical downturns from time to time, during which economic activity has been impacted by falling demand for goodsand services, restricted credit, poor liquidity, reduced corporate profitability, volatility in credit, equity, and foreign exchange markets, bankruptcies, and economicuncertainty. These changes in global economic conditions could impact the ability and willingness of our clients to make investments in technology, which in turnmay delay or13reduce the purchases of our software and services. These factors could also impact the ability and willingness of these clients to pay their trade obligations andhonor their contractual commitments. These clients may also become subject to increasingly restrictive regulatory requirements, which could limit or delay theirability to proceed with technology purchases and may result in longer sales cycles, increased price competition, and reductions in sales of our products andservices. The financial uncertainties facing many of our clients and the industries in which they operate could negatively impact our business, operating results, andfinancial condition.We have historically sold to the financial services, healthcare, insurance, and communications markets, and rapid changes or consolidation in these marketscould affect the level of demand for our products.We have historically derived a significant portion of our revenue from clients in the financial services, healthcare, insurance, and communications markets, andsales to these markets are important for our future growth. Competitive pressures, industry consolidation, decreasing operating margins, regulatory changes, andprivacy concerns affect the financial condition of our clients and their willingness to buy. In addition, clients’ purchasing patterns in these industries for largetechnology projects are somewhat discretionary. The financial services and insurance markets continue to undergo intense domestic and internationalconsolidation, and consolidation has increased in the healthcare and communications markets. Consolidation may interrupt normal buying behaviors and increasethe volatility of our operating results. In recent years, several of our clients have merged or consolidated, and we expect this to continue in the future. Futuremergers or consolidations may cause a decline in revenues and adversely affect our future financial performance. All of these factors affect the level of demand forour products from clients in these industries, and could adversely affect our business, operating results, and financial condition.Risks Related to Information Technology Resilience and SecurityWe face risks related to outages, data losses, and disruptions of our online services if we fail to maintain an adequate operations infrastructure.The increasing user traffic for our cloud offering demands more computing power. It requires that we maintain an internet connectivity infrastructure that is robustand reliable within competitive and regulatory constraints that continue to evolve. Inefficiencies or operational failures, including temporary or permanent loss ofclient data, power outages, or telecommunications infrastructure outages, by us or our third-party service providers could diminish the quality of our userexperience resulting in contractual liability, claims by clients and other third parties, damage to our reputation, loss of current and potential clients, and harm to ouroperating results and financial condition.Security of our systems and of global client data is a growing challenge on many fronts. Cyber-attacks and security breaches may expose us to significant legaland financial liabilities.Our cloud offering provides Pega Platform environments that are provisioned, monitored, and maintained for individual clients to create and deploy Pega-basedapplications using an Internet-based infrastructure. These services involve the storage and transmission of clients’ data and other confidential information. Securitybreaches could expose us and our clients to a risk of loss or misuse of this information. Any security breach could result in a loss of confidence in the security ofour services, damage our reputation, disrupt our business, lead to legal liability, and negatively impact our future sales. High-profile security breaches at othercompanies have increased in recent years, and security industry experts and government officials have warned about the risks of hackers and cyber-attackerstargeting information technology products and businesses. Threats to IT security can take a variety of forms. Individual hackers, groups of hackers, andsophisticated organizations including state-sponsored organizations or nation-states themselves, may take steps that pose threats to our clients and to our ITstructure.Our security measures, and those of our clients, may be breached because of third-party actions, or that of employees, consultants, or others, including intentionalmisconduct by computer hackers, system error, human error, technical flaws in our products, or otherwise. The techniques used to obtain unauthorized access or tosabotage systems change frequently and generally are not recognized until launched against a target. While we have invested in the protection of our data andsystems and of our clients’ data to reduce these risks, there can be no assurance that our efforts will prevent breaches. We carry data breach insurance coverage tomitigate the financial impact of a breach, though this may prove insufficient in the event of a breach.Our cloud offering involves the hosting of clients’ applications on the servers of third-party technology providers. We also rely on third-party systems andtechnology, including encryption, virtualized infrastructure and support, and we employ a shared security model with our clients and our third-party technologyproviders. Because we do not control the configuration of Pega applications by our clients, the transmissions between our clients and our third-party technologyproviders, the processing of data on the servers at third-party technology providers, or the internal controls maintained by our clients and third-party technologyproviders that could prevent unauthorized access or provide appropriate data encryption, we cannot fully ensure the complete integrity or security of suchtransmissions processing or controls. In addition, privacy, security, and data transmission concerns in some parts of the world may inhibit demand for our cloudoffering or lead to requirements to provide our products or services in configurations that may increase the cost of serving such markets.To defend against security threats, we need to continuously engineer products and services with enhanced security and reliability features, improve the deploymentof software updates to address security vulnerabilities, apply technologies that mitigate the risk of14attacks, and maintain a digital security infrastructure that protects the integrity of our network, products, and services. The cost of these steps could negativelyimpact our operating results.We may experience significant errors or security flaws in our products and services, and could face privacy, product liability, and warranty claims as a result.Despite quality testing prior to its release, our software frequently contains errors or security flaws, especially when first introduced or when new versions arereleased. Errors in our software could affect its ability to work with hardware or other software or could delay the development or release of new products or newversions of our software. Additionally, the detection and correction of any security flaws can be time consuming and costly. Errors or security flaws in our softwarecould result in the inadvertent disclosure of confidential information or personal data relating to our clients, employees, or third parties. Software errors andsecurity flaws in our products or services could expose us to privacy, product liability, and/or warranty claims as well as harm our reputation, which could impactour future sales of products and services. Typically, we enter into license agreements that contain provisions intended to limit the nature and extent of our risk ofproduct liability and warranty claims. There is a risk that a court might interpret these terms in a limited way or could hold part or all of these terms to beunenforceable. Also, there is a risk that these contract terms might not bind a party other than the direct client. Furthermore, some of our licenses with our clientsare governed by non-U.S. law, and there is a risk that foreign law might give us less or different protection. Although we have not experienced any materialproduct liability claims to date, a product liability suit or action claiming a breach of warranty, whether meritorious, could result in substantial costs and a diversionof management’s attention and our resources.Risks Related to Government Regulation and Intellectual PropertyThe formal notification by the U.K. of its intention to withdraw from the EU (commonly referred to as “Brexit”) could have a material impact on our business,including our relationships with existing and future clients, suppliers, and employees, which could have an adverse effect on our financial results andoperations.Pursuant to the U.K.’s referendum in June 2016, in which a majority voted in favor of the U.K.’s exit from the EU, the British government is negotiating the futureterms of the U.K.’s relationship with the EU. The final terms of the U.K.’s relationship with the EU after exit are not currently known. We have material operationsin the U.K. and larger EU. The ultimate effects, or perceived effects, of the U.K.’s decision could potentially disrupt the markets we serve and the tax jurisdictionsin which we operate. In addition, Brexit could lead to legal uncertainty as the U.K. determines which EU laws to replace or replicate.We are subject to increasingly complex U.S. and foreign laws and regulations, requiring costly compliance measures, and any failure to comply with theselaws and regulations could subject us to, among other things, penalties and legal expenses that could harm our reputation or have a material adverse effect onour business, financial condition, and results of operations.We are subject to extensive federal, state, and foreign laws and regulations, including but not limited to the U.S. Foreign Corrupt Practices Act, the U.K. BriberyAct, data privacy and security laws, and similar laws and regulations. The Foreign Corrupt Practices Act, the U.K. Bribery Act, and similar foreign anti-briberylaws generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business. Similar laws andregulations exist in many other countries throughout the world in which we do or intend to do business. Data privacy laws and regulations in Europe, Australia,Latin America and elsewhere are undergoing rapid transformation toward increased restrictions.In April 2016, the European Parliament adopted the General Data Protection Regulation (“GDPR”). It became effective in May 2018. The GDPR extends the scopeof European privacy laws to any entity which controls or processes personal data of EU residents in connection with the offer of goods or services or themonitoring of behavior and imposes new compliance obligations concerning the handling of personal data. Complying with the GDPR and other emerging andchanging requirements caused us to incur additional costs in fiscal year 2018 and may cause us to incur substantial additional costs or require us to change ourbusiness practices. Compliance also depends on how regulators choose to interpret and apply the new requirements. Moreover, non-compliance, or if regulatorsassert we have not complied, with GDPR could result in significant monetary penalties of up to the higher of 20 million Euro or 4% of annual worldwide revenue,private lawsuits, and damage to our reputation, which could have a material adverse effect on our business, operating results, and financial condition.We have developed and implemented a compliance program based on what we believe are current best practices, including the background checking of our currentpartners and prospective clients and partners. We cannot guarantee, however, that we, our employees, our consultants, our partners, or our contractors are or will becompliant with all federal, state, and foreign regulations, particularly as we expand our operations outside of the U.S. If we or our representatives fail to complywith any of these laws or regulations, a range of fines, penalties, and/or other sanctions could be imposed on us, which could have a material adverse effect on ourbusiness, financial condition, and results of operations. Even if we are determined not to have violated these laws, government inquiries into these issues typicallyrequire the expenditure of significant resources and generate negative publicity, which could also have an adverse effect on our business. In addition, regulation ofdata privacy and security laws is increasing worldwide, including various restrictions on cross-border access or transfer of data, including personal data of ouremployees, our clients, and customers of15our clients. Compliance with such regulations may increase our costs and there is a risk of enforcement of such laws resulting in damage to our brand, as well as,financial penalties and potential loss of business, which could be significant.We may have exposure to greater than anticipated tax liabilities.The determination of our worldwide provision for income taxes and other tax liabilities requires estimation and significant judgment, and there are manytransactions and calculations where the ultimate tax determination is uncertain. Like many other multinational corporations, we are subject to tax in multiple U.S.and foreign jurisdictions. Our determination of our tax liability is always subject to audit and review by applicable domestic and foreign tax authorities, and we arecurrently undergoing a number of inquiries , audits, and reviews by taxing authorities throughout the world. Any adverse outcome of any such audit or reviewcould harm our business, and the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financialresults in the period or periods for which such determination is made. While we have established reserves based on assumptions and estimates that we believe arereasonable to cover such eventualities, these reserves may prove to be insufficient.In addition, our future income taxes could be adversely affected by a shift in our jurisdictional earning mix, by changes in the valuation of our deferred tax assetsand liabilities, as a result of changes in tax laws, regulations, or accounting principles, as well as by certain discrete items.In light of continuing fiscal challenges in many jurisdictions, various levels of government are increasingly focused on tax reform and other legislative action toincrease tax revenue, including corporate income taxes. A number of U.S. states have attempted to increase corporate tax revenues by taking an expansive view ofcorporate presence to attempt to impose corporate income taxes and other direct business taxes on companies that have no physical presence in their state, andtaxing authorities in foreign jurisdictions may take similar actions. Many U.S. states are also altering their apportionment formulas to increase the amount oftaxable income or loss attributable to their state from certain out-of-state businesses. Similarly, in Europe, and elsewhere in the world, there are various tax reformefforts underway designed to ensure that corporate entities are taxed on a larger percentage of their earnings.If it becomes necessary to repatriate any of our foreign cash balances to the United States, we may be subject to increased income taxes, other restrictions, andlimitations .As of December 31, 2018 , approximately $63.9 million of our cash and cash equivalents was held in our foreign subsidiaries. If we are unable to reinvest this cashoutside of the U.S., we may have to repatriate some of our foreign cash to the U.S. which would increase our income tax liability. If it becomes necessary torepatriate these funds, we may be required to pay U.S. state and local taxes, as well as foreign taxes, upon repatriation. We consider the earnings of our foreignsubsidiaries to be permanently reinvested and, as a result, U.S. state, U.S. local, and foreign taxes on such earnings have not been provided. It is impractical toestimate the amount of U.S. state, U.S. local, and foreign tax we would have to pay upon repatriation due to the complexity of the income tax laws and the effectsof the Tax Reform Act and other factors.We face risks related to intellectual property claims or appropriation of our intellectual property rights.We rely primarily on a combination of copyright, trademark, and trade secrets laws, as well as intellectual property and confidentiality agreements to protect ourproprietary rights. We also try to control access to and distribution of our technologies and other proprietary information. We have obtained patents in strategicallyimportant global markets relating to the architecture of our systems. We cannot assure that such patents will not be challenged, invalidated, or circumvented or thatrights granted thereunder, or the claims contained therein will provide us with competitive advantages. Moreover, despite our efforts to protect our proprietaryrights, unauthorized parties may attempt to copy aspects of our software or to obtain the use of information that we regard as proprietary. Although we generallyenter into intellectual property and confidentiality agreements with our employees and strategic partners, despite our efforts our former employees may seekemployment with our business partners, clients, or competitors, and there can be no assurance that the confidential nature of our proprietary information will bemaintained. In addition, the laws of some foreign countries do not protect our proprietary rights as effectively as they do in the U.S. There can be no assurance thatour means of protecting our proprietary rights will be adequate or that our competitors will not independently develop similar technology.Other companies or individuals have obtained proprietary rights covering a variety of designs, processes, and systems. There can be no assurance that third parties,including clients, will not claim infringement by us with respect to current or future products. Although we attempt to limit the amount and type of our contractualliability for infringement of the proprietary rights of third parties and assert ownership of work product and intellectual property rights as appropriate, there areoften exceptions, and limitations may not be applicable and enforceable in all cases. Even if limitations are found to be applicable and enforceable, our liability toour clients for these types of claims could be material given the size of certain of our transactions. We expect that software product developers will increasingly besubject to infringement claims as the number of products and competitors in our industry segment grows and the functionality of products in different industrysegments overlaps. Any such claims, with or without merit, could be time-consuming, result in costly litigation, cause product shipment and delivery delays,require us to enter into royalty or licensing agreements, or be precluded from making and selling the infringing software, if such proprietary rights are found to bevalid. Royalty or licensing agreements, if required, may not be available on terms acceptable to us or at all, which could have a material adverse effect upon ourbusiness, operating results, and financial condition.16ITEM 1B.

Revenue fromcloud arrangements is generally recognized over the service period, while revenue from license arrangements is generally recognized upfront when the licenserights become effective.Subscription revenueThe decrease in term license revenue in 2018 , and increase in 2017 , was primarily due to $35.3 million of revenue recognized in the three months ended March31, 2017 from a large term license renewal. The increases in cloud revenue in 2018 and 2017 reflect the shift in client preferences to cloud arrangements fromother types of arrangements.

See "Our consulting revenue is significantly dependent upon our consulting personnelimplementing new license and cloud arrangements" in Item 1A of this Annual Report for additional information.Consulting revenue was substantially consistent in 2018 with 2017 as a decrease in billable hours in 2018 from a large project which began in the second half of2016 was offset by an increase in revenue from a large number of other projects. The increase in consulting revenue in the 2017 was primarily due to an increase inbillable hours driven by the same large project which began in the second half of 2016.Gross profit(Dollars in thousands) Change2018 2017 2016 2018 vs. 2017 2017 vs. 2016Software license$282,95098% $334,20999% $292,34198% (15)%14%Maintenance239,31091% 214,41588% 193,13088% 12 %11%Cloud45,21855% 27,32653% 18,34045% 65 %49%Consulting22,3389% 32,84413% 19,1629% (32)%71%Total gross profit$589,81666% $608,79469% $522,97369% (3)%16%The recent shift in our revenue mix toward cloud arrangements may result in slower total gross profit growth in the near term as our cloud business continues togrow and scale.

We historically used foreign currency forward contracts to hedge our exposure to fluctuations in foreign currency exchange ratesassociated with our foreign currency denominated cash, accounts receivable, and intercompany receivables and payables held primarily by our U.S. parentcompany and its U.K. subsidiary. The total change in the fair value of our foreign currency forward contracts recorded in other income (expense), net, during 2017and 2016 was a gain of $0.3 million and a loss of $5.6 million, respectively.

The Company expects that the changes in the unrecognized benefits within the next twelve months will be approximately $0.5 million due to alapse of applicable statute of limitations.2017 Compared to 2016The decrease in our effective income tax rate was primarily due to an increase in excess tax benefits on share-based payments recognized in income tax expensealong with an additional benefit of $14.2 million recorded in 2017 to re-measure our deferred income taxes under ASC 606 to the new U.S. statutory tax rate as aresult of the Tax Cuts and Jobs Act.As of December 31, 2017 and 2016 , we had $19.2 million and $22.7 million , respectively, of total unrecognized tax benefits, which would decrease our effectivetax rate if recognized.LIQUIDITY AND CAPITAL RESOURCES(in thousands)2018 2017 2016Cash provided by (used in): Operating activities$104,356 $158,235 $39,874Investing activities(48,196) (14,759) (7,172)Financing activities(101,460) (54,229) (51,716)Effect of exchange rate on cash and cash equivalents(2,557) 2,438 (3,418)Net (decrease) increase in cash and cash equivalents$(47,857) $91,685 $(22,432) December 31,(in thousands)2018 2017 2016Held in U.S. entities$143,533 $136,444 $82,008Held in foreign entities63,890 87,304 51,753Total cash, cash equivalents, and marketable securities$207,423 $223,748 $133,761We believe that our current cash, cash equivalents, marketable securities, and cash flow from operations will be sufficient to fund our operations, quarterly cashdividends, and stock repurchases for at least the next 12 months.If it becomes necessary to repatriate foreign funds, we may be required to pay U.S. state and local taxes, as well as foreign taxes, upon repatriation. Due to thecomplexity of income tax laws and regulations, it is impracticable to estimate the amount of taxes we would have to pay. See "If it becomes necessary to repatriateany of our foreign cash balances to the United States, we may be subject to increased income taxes, other restrictions, and limitations" in Item 1A of this AnnualReport for additional information.Cash provided by operating activitiesWe expect client preferences to continue to shift in favor of cloud arrangements, which could result in slower operating cash flow growth in the near term. Cashfrom cloud arrangements is typically collected over the service period, while cash from perpetual license arrangements is typically collected upfront, shortly afterthe license rights become effective.The primary cash drivers during 2018 were net income of $10.6 million and $25.8 million from accounts receivable, largely due to increased cash collections andthe timing of billings.The primary cash driver during 2017 was net income of $98.5 million .The primary cash driver during 2016 was net income of $45 million .26Cash used in investing activitiesCash used in investing activities is primarily driven by the timing of investment maturities and purchases of new investments.During 2018 , we purchased $69.5 million of investments, primarily marketable debt securities, and made investments of $11.9 million in property and equipment,partially offset by proceeds received from maturities of investments, including called investment securities of $34 million .During 2017 , we purchased $27.7 million of investments, primarily marketable debt securities, and made investments of $13.7 million in property and equipment,partially offset by proceeds received from maturities of investments, including called investment securities of $27 million.During 2016 , we acquired OpenSpan, Inc. for $48.8 million, net of cash acquired, and invested $19.1 million primarily in internally developed software andleasehold improvements at our corporate headquarters and our office in Hyderabad, India, partially offset by proceeds received from the sales of investments of$62.2 million.Cash used in financing activitiesWe used cash primarily for repurchases of our common stock under our stock repurchase programs, stock repurchases for tax withholdings for the net settlement ofour equity awards, and the payment of our quarterly dividend.Net cash used in financing activities during 2018 , 2017 , and 2016 was primarily for repurchases of our common stock and the payment of our quarterly dividend.Dividends(in thousands)2018 2017 2016Dividend payments to shareholders$9,432 $9,277 $9,174It is our current intention to pay a quarterly cash dividend of $0.03 per share, however, the Board of Directors may terminate or modify this dividend program atany time without prior notice.Stock repurchase program (1) Remaining authority under existing programs is:(in thousands)2018January 1,$34,892Authorizations27,003Repurchases(55,275)December 31,$6,620(1) Purchases under these programs have been made on the open market.

Properties" of this Annual Report for additional information.CRITICAL ACCOUNTING ESTIMATES AND SIGNIFICANT JUDGMENTSManagement’s discussion and analysis of the financial condition and results of operations is based upon our consolidated financial statements, which have beenprepared in accordance with accounting principles generally accepted in the U.S. and the rules and regulations of the SEC for annual financial reporting. Thepreparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses,and related disclosure of contingent assets and liabilities. We base our estimates and judgments on historical experience, knowledge of current conditions andbeliefs of what could occur in the future given available information.We believe that, of our significant accounting policies, which are described in “ 2. Significant Accounting Policies ” in Item 8 of this Annual Report, the followingaccounting policies are most important to the portrayal of our financial condition and require the most subjective judgment. Accordingly, these are the policies webelieve are the most critical to aid in fully understanding and evaluating our consolidated financial condition and results of operations. If actual results differsignificantly from management’s estimates and projections, there could be a material effect on our financial statements.Revenue recognitionWe account for revenue in accordance with ASC 606. Our revenue recognition policies require us to make significant judgments and estimates.Our clients’ contracts with us typically contain promises by us to provide multiple products and services. Specifically, contracts associated with sales of theCompany Pega Platform and other software applications, sold either as licenses to use functional intellectual property or as a cloud-based solution, typicallyinclude various forms of consulting. Determining whether such products and services within a client contract are considered distinct performance obligations thatshould be accounted for separately requires significant judgment. We review client contracts to identify all separate promises to transfer goods and services thatwould be considered performance obligations. Judgment is also required in determining whether an option to acquire additional products and services within aclient contract represents a material right that the client would not receive without entering into the contract.We allocate the transaction price to the distinct performance obligations, including options in contracts that are determined to represent a material right, based onrelative standalone selling price of each performance obligation. Judgment is required in estimating standalone selling prices. We maximize the use of observableinputs by maintaining pricing analysis that includes our pricing policies, historical standalone sales when they exist, and historical renewal prices charged toclients. We have concluded that the standalone selling prices of certain performance obligations, specifically the standalone selling prices for software licenses andcloud arrangements, are highly variable. In these instances, we estimate the standalone selling prices using the residual approach, determined based on totaltransaction price minus the standalone selling price of other performance obligations promised in the contract. We update our standalone selling price analysisperiodically, which includes a re-assessment as to whether the residual approach used to determine the standalone selling prices for software licenses and cloudarrangements remains appropriate.Changes in the assumptions or judgments used in determining the performance obligations in client contracts and used in determining standalone selling pricescould have a significant impact on the timing and amount of revenue we report in a particular period.28Goodwill and intangible assets impairmentOur goodwill and intangible assets result from our previous business acquisitions. Goodwill and intangible assets with indefinite useful lives are not amortized butare tested for impairment at least annually or as circumstances indicate their value may no longer be recoverable. We do not carry any intangible assets withindefinite useful lives other than goodwill. We perform our annual goodwill impairment as of November 30th of each fiscal year. To assess if goodwill is impaired,we first perform a qualitative assessment to determine whether further impairment testing is necessary. If, based on the qualitative assessment, we consider it more-likely-than-not that the fair value of our reporting unit is less than its carrying amount, we perform a quantitative impairment test in a two-step process. For the firststep, we screen for impairment, and if any possible impairment exists, we undertake a second step of measuring such impairment by performing discounted cashflow analysis. This analysis is based on cash flow assumptions that are consistent with the plans and estimates being used to manage our business. In the first step,we review the carrying amount of our reporting unit compared to the “fair value” of the reporting unit. An excess carrying value over fair value would indicate thatgoodwill may be impaired. If we determined that goodwill may be impaired, then we would compare the “implied fair value” to the carrying value of the goodwill.We periodically re-evaluate our business and have determined that we have one operating segment and one reporting unit. If our assumptions change in the future,we may be required to record impairment charges to reduce the carrying value of our goodwill. Changes in the valuation of goodwill could materially impact ouroperating results and financial position. We evaluate our intangible assets for impairment whenever events or changes in circumstances indicate that the carryingamount of such assets may not be recoverable. In evaluating potential impairment of these assets, we specifically consider whether any indicators of impairmentare present, including, but not limited to:•whether there has been a significant adverse change in the business climate that affects the value of an asset;•whether there has been a significant change in the extent or way an asset is used; and•whether there is an expectation that the asset will be sold or disposed of before the end of its originally estimated useful life.If indicators of impairment are present, we compare the estimated undiscounted cash flows that the specific asset is expected to generate to its carrying value. Thekey assumptions of the cash flow model involve significant subjectivity. If such assets are impaired, the impairment recognized is measured by the amount bywhich the carrying amount of the asset exceeds its fair value.As of December 31, 2018 , we had $72.9 million of goodwill and $21.2 million of intangible assets. If our estimates or the related assumptions change in thefuture, we may be required to record impairment charges to reduce or eliminate the carrying value of these assets. Changes in the valuation of long-lived assetscould materially impact our operating results and financial position. To date, there have been no impairments of goodwill or intangible assets.Accounting for income taxesSignificant judgment is required in determining our provision for income taxes and income tax assets and liabilities, including evaluating uncertainties in theapplication of accounting principles and complex tax laws. Changes in tax laws or our interpretation of tax laws and the resolution of any tax audits couldsignificantly impact our financial statements.We regularly assess the need for a valuation allowance against our deferred tax assets. Future realization of our deferred tax assets ultimately depends on theexistence of sufficient taxable income within the available carryback or carryforward periods. We record a valuation allowance to reduce our deferred tax assets toan amount we believe is more likely than not to be realized. Changes in our valuation allowance impact income tax expense in the period of adjustment. Ourdeferred tax valuation allowance requires significant judgment and uncertainties, including assumptions about future taxable income that are based on historicaland projected information.We assess our income tax positions and record tax benefits based upon management’s evaluation of the facts, circumstances, and information available at thereporting date. For those tax positions where it is more-likely-than-not that a tax benefit will be sustained, we record the largest amount of tax benefit with a greaterthan 50 percent likelihood of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevant information. For those incometax positions where it is not more-likely-than-not that a tax benefit will be sustained, no tax benefit is recognized in the financial statements.As a global company, we use significant judgment to calculate and provide for income taxes in each of the tax jurisdictions in which we operate. In the ordinarycourse of our business, there are transactions and calculations undertaken whose ultimate tax outcome cannot be certain. Some of these uncertainties arise as aconsequence of transfer pricing for transactions with our subsidiaries and nexus and tax credit estimates. In addition, the calculation of acquired tax attributes andthe associated limitations are complex. We estimate our exposure to unfavorable outcomes related to these uncertainties and estimate the probability of suchoutcomes.Although we believe our estimates are reasonable, no assurance can be given that the final tax outcome will not be different from what is reflected in our historicalincome tax provisions, returns, and accruals. Such differences, or changes in estimates relating to potential differences, could have a material impact on our incometax provision and operating results in the period in which such a determination is made.See "15.

We also have audited the Company’s internal control over financial reporting as of December 31, 2018 ,based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017 , andthe results of its operations and its cash flows for each of the three years in the period ended December 31, 2018 , in conformity with accounting principles generally accepted inthe United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018 ,based on criteria established in Internal Control – Integrated Framework (2013) issued by COSO.Basis for OpinionsThe Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of theeffectiveness of internal control over financial reporting, included in the accompanying Management’s Report on and Changes in Internal Control over Financial Reporting. Ourresponsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are apublic accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to theCompany in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance aboutwhether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintainedin all material respects.Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, andperforming procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements.Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financialstatements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a materialweakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such otherprocedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.Change in Accounting PrinciplesAs discussed in "Note 2. Significant Accounting Policies" to the financial statements, the Company adopted Accounting Standards Codification (ASC) Topic 606, “Revenuefrom Contracts with Customers,” using the full retrospective adoption method on January 1, 2018.Definition and Limitations of Internal Control over Financial ReportingA company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation offinancial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes thosepolicies 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 thecompany; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally acceptedaccounting 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 materialeffect 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 tofuture 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 maydeteriorate./s/ DELOITTE & TOUCHE LLPBoston, MassachusettsFebruary 20, 2019We have served as the Company’s auditor since 2000.32PEGASYSTEMS INC.CONSOLIDATED BALANCE SHEETS (1) (in thousands, except per share amounts) December 31, 2018 2017Assets Current assets: Cash and cash equivalents$114,422 $162,279Marketable securities93,001 61,469Total cash, cash equivalents, and marketable securities207,423 223,748Accounts receivable180,872 222,735Unbilled receivables172,656 160,084Other current assets49,684 41,135Total current assets610,635 647,702Long-term unbilled receivables151,237 160,708Goodwill72,858 72,952Other long-term assets147,823 131,391Total assets$982,553 $1,012,753 Liabilities and Stockholders’ Equity Current liabilities: Accounts payable$16,487 $17,370Accrued expenses45,506 45,508Accrued compensation and related expenses84,671 66,040Deferred revenue185,145 165,850Total current liabilities331,809 294,768Deferred income tax liabilities6,939 38,463Other long-term liabilities22,274 23,652Total liabilities361,022 356,883Commitments and Contingencies (Note 19) Stockholders’ equity: Preferred stock, $0.01 par value, 1,000 shares authorized; none issued— —Common stock, $0.01 par value, 200,000 shares authorized; 78,526 and 78,081 shares issued and outstanding atDecember 31, 2018 and 2017, respectively785 781Additional paid-in capital123,205 152,097Retained earnings510,863 509,697Accumulated other comprehensive loss: Net unrealized loss on available-for-sale marketable securities, net of tax(249) (232)Foreign currency translation adjustments(13,073) (6,473)Total stockholders’ equity621,531 655,870Total liabilities and stockholders’ equity$982,553 $1,012,753(1) On January 1, 2018, the Company adopted the ASC 606 revenue recognition standard and adjusted prior periods to conform.

BASIS OF PRESENTATIONBusinessThe Company develops, markets, licenses, and supports customer engagement and digital process automation software applications in addition to the PegaPlatform™ for clients that wish to build and extend their own applications. The Company provides consulting, training, support, and hosting services to facilitatethe use of its software.Management estimates and reportingThe preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S.”) requires managementto make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of thefinancial statements and the reported amounts of revenues and expenses during the periods presented. Actual results could differ from those estimates. Accountswith reported amounts based on significant estimates and judgments include, but are not limited to, revenue, unbilled receivables, deferred revenue, deferredincome taxes, deferred contract costs, income taxes payable, intangible assets, and goodwill.On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”, using thefull retrospective method which required that each prior reporting period presented be adjusted to reflect the application of this ASU. See "Note 2. SignificantAccounting Policies" for additional information.Principles of consolidationThe Company’s consolidated financial statements reflect Pegasystems Inc. and subsidiaries in which the Company holds a controlling financial interest.2. SIGNIFICANT ACCOUNTING POLICIESRevenueThe Company’s revenue is primarily derived from:•software license revenue from sales of the Company’s Pega Platform and software applications. Software licenses represent functional intellectualproperty and are delivered separately from maintenance and services.•maintenance revenue from client support including software upgrades (on a when and-if available basis), telephone support, and bug fixes or patches.•services revenue from cloud revenue, which is sales of the Company’s hosted Pega Platform and software applications, and consulting revenue, which isprimarily related to new software license implementations, training, and reimbursable costs.Performance ObligationsThe Company’s software license and cloud arrangements often contain multiple performance obligations. For contracts with multiple performance obligations, theCompany accounts for individual performance obligations separately if they are distinct. Transaction price is allocated to the separate performance obligations on arelative stand-alone selling price basis. If the transaction price contains discounts or the Company expects to provide a future price concession, these elements areconsidered when determining the transaction price prior to allocation. The Company’s policy is to exclude from the determination of transaction price sales andsimilar taxes collected from clients.38The Company’s typical performance obligations are:Performance Obligation How Standalone Selling Price is TypicallyDetermined When Performance Obligation is TypicallySatisfied When Payment is TypicallyDuePerpetual license Residual approach Upon transfer of control to the client, defined whenthe client can use and benefit from the license (pointin time) Effective date of the licenseTerm license Residual approach Upon transfer of control to the client, defined whenthe client can use and benefit from the license (pointin time) Annually, or more frequently,over the term of the licenseMaintenance Consistent pricing relationship as a percentage of therelated license and observable in stand-alone renewaltransactions (1) Ratably over the term of the maintenance (over time) Annually, or more frequently,over the term of maintenanceConsulting- time and materials Observable hourly rate for time and materials-basedservices in similar geographies for similar contractsizes Based on hours incurred to date MonthlyConsulting- fixed price Observable hourly rate for time and materials-basedservices in similar geographies for similar contractsizes multiplied by estimated hours for the project Based on hours incurred as a percentage of totalestimated hours As contract milestones areachievedCloud Residual approach Ratably over the term of the service (over time) Annually, or more frequently,over the term of the service(1) Technical support and software updates are considered distinct services but accounted for as a single performance obligation, as they have the same pattern of transfer to theclient.The Company utilizes the residual approach for performance obligations since the selling price is highly variable and stand-alone selling price is not discerniblefrom past transactions or other observable evidence. Periodically, the Company reevaluates whether the residual approach remains appropriate. As required theCompany evaluates its residual approach estimate compared to all available observable data in order to conclude the estimate is representative of its standaloneselling price.If the contract grants the client the option to acquire additional products or services, the Company assesses whether the option represents a material right to theclient that the client would not receive without entering into that contract. Discounts on options to purchase additional products and services that are in excess ofdiscounts available to similar clients are accounted for as an additional performance obligation.Variable considerationThe Company’s arrangements can include variable fees, such as the option to purchase additional usage of a previously delivered software license. In addition, theCompany may provide pricing concessions to clients, a business practice that also gives rise to variable fees in contracts. The Company includes in thedetermination of total transaction price an estimate of variable fees if it is probable that a significant reversal of cumulative revenue recognized will not occur. TheCompany uses the expected value method to estimate variable consideration and the estimates are based on expected purchase volumes and the level of historicalprice concessions offered to clients.Significant financing componentsThe Company generally does not intend to provide financing to its clients, as financing arrangements are not contemplated as part of the negotiated terms ofcontracts between the Company and its clients. Although there may be instances with an intervening period between the delivery of the license and the payment,typically in term license arrangements, the purpose of that timing difference is to align the client’s payment with the timing of the use of the software license orservice.In certain circumstances, however, there are instances where the timing of revenue recognition differs from the timing of payment due to extended payment termsor fees that are non-proportional to the associated usage of software licenses. In these instances, the Company evaluates whether a significant financing componentexists. This evaluation includes determining the difference between the consideration the client would have paid at the time the performance obligation wassatisfied and the amount of consideration actually paid. Contracts that include a significant financing component are adjusted for the time value of money at therate inherent in the contract, the client’s borrowing rate, or the Company’s incremental borrowing rate depending upon the recipient of the financing.During 2018, 2017 and 2016, significant financing components were not material.Contract modificationsThe Company assesses contract modifications to determine:•if the additional products and services are distinct from the products and services in the original arrangement; and•if the amount of consideration expected for the added products and services reflects the stand-alone selling price of those products and services.39A contract modification meeting both criteria is accounted for as a separate contract. A contract modification not meeting both criteria is considered a change to theoriginal contract and is accounted for on either:•a prospective basis as a termination of the existing contract and the creation of a new contract; or•a cumulative catch-up basis.Deferred contract costsThe Company recognizes an asset for the incremental costs of obtaining a client contract, primarily related to sales commissions, if the Company expects to benefitfrom those costs for more than one year . Deferred contract costs are allocated to each performance obligation within the contract and amortized over the expectedbenefit period of the related performance obligations. The expected benefit period is determined based on the length of the client contracts, client attrition rates, theunderlying technology life-cycle, and the influence of the competitive marketplace in which the products and services are sold. Deferred costs for maintenancerenewals and cloud arrangements are amortized over an average expected benefit period of five years . Deferred costs for software licenses and consulting areamortized over a period that is consistent with the pattern of transfer of control for the related products and services.Financial instrumentsThe principal financial instruments held by the Company consist of cash equivalents, marketable securities, receivables, and accounts payable. The Companyconsiders debt securities that are readily convertible to known amounts of cash with maturities of three months or less from the purchase date to be cashequivalents. Interest is recorded when earned. All of the Company’s investments are classified as available-for-sale and are carried at fair value. Unrealized gainsand losses considered to be temporary in nature are recorded as a component of accumulated other comprehensive loss, net of related income taxes. The Companyreviews all investments for reductions in fair value that are other-than-temporary. When such reductions occur, the cost of the investment is adjusted to fair valuethrough recording a loss on investments in the consolidated statements of operations. Gains and losses on investments are calculated based upon the specificinvestment.See "Note 4. Receivables, Contract Assets, And Deferred Revenue" and "Note 11. Fair Value Measurements" for additional information.Property and equipmentProperty and equipment are recorded at cost. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of theassets, which are three years for computer equipment and five years for furniture and fixtures. Leasehold improvements are amortized over the lesser of the term ofthe lease or the useful life of the asset. Repairs and maintenance costs are expensed as incurred.Internal-use softwareThe Company capitalizes and amortizes certain direct costs associated with computer software developed or purchased for internal use incurred during theapplication development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. The Company amortizescapitalized software costs generally over three to five years, commencing on the date the software is placed into service.GoodwillGoodwill represents the residual purchase price paid in a business combination after the fair value of all identified assets and liabilities have been recorded.Goodwill is not amortized. The Company has a single reporting unit. The Company performed a qualitative assessment as of November 30, 2018 , 2017 , and 2016, and concluded that there was no impairment since it was not more likely than not that the fair value of its reporting unit was less than its carrying value.Intangible and long-lived assetsAll of the Company’s intangible assets are amortized using the straight-line method over their estimated useful life. The Company evaluates its long-lived tangibleand intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.Impairment is assessed by comparing the undiscounted cash flows expected to be generated by the intangible asset to its carrying value. If impairment exists, theCompany calculates the impairment by comparing the carrying value of the intangible asset to its fair value as determined by discounted expected cash flows.The Company did not have any impairments in the 2018 , 2017 , or 2016 .Business combinationsThe Company uses its best estimates and assumptions to accurately assign fair value to the tangible and intangible assets acquired and liabilities assumed at theacquisition date. The Company’s estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year fromthe acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with thecorresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially established in connection with a businesscombination as of the acquisition date. The40Company continues to collect information and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminaryestimates to goodwill provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of thefair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s consolidated statements ofoperations.Research and development and software development costsResearch and development costs are expensed as incurred. Capitalization of computer software developed for resale begins upon the establishment of technologicalfeasibility, generally demonstrated by a working model or an operative version of the computer software product. Such costs have not been material to date, astechnological feasibility is established within a short time frame from the software’s general availability and, as a result, no costs were capitalized in 2018 , 2017 ,or 2016 .Stock-based compensationThe Company recognizes stock-based compensation expense associated with equity awards based on the fair value of these awards at the grant date. Stock-basedcompensation is recognized over the requisite service period, which is generally the vesting period of the equity award and is adjusted each period for anticipatedforfeitures. See "Note 13. Stock-Based Compensation" for discussion of the Company’s key assumptions included in determining the fair value of its equity awardsat the grant date.Foreign currency translation and remeasurementThe translation of assets and liabilities for the Company’s subsidiaries with functional currencies other than the U.S. dollar are made at period-end exchange rates.Revenue and expense accounts are translated at the average exchange rates during the period transactions occurred. The resulting translation adjustments arereflected in accumulated other comprehensive income. Realized and unrealized exchange gains or losses from transactions and remeasurement adjustments arereflected in foreign currency transaction gain (loss) in the accompanying consolidated statements of operations.Accounting for income taxesThe Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based ontemporary differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differencesare expected to reverse. The Company regularly assesses the need for a valuation allowance against its deferred tax assets. Future realization of the Company’sdeferred tax assets ultimately depends on the existence of sufficient taxable income within the available carryback or carryforward periods. Sources of taxableincome include taxable income in prior carryback years, future reversals of existing taxable temporary differences, tax planning strategies, and future taxableincome. The Company records a valuation allowance to reduce its deferred tax assets to an amount it believes is more-likely-than-not to be realized. Changes in thevaluation allowance impacts income tax expense in the period of adjustment. The Company’s deferred tax valuation allowance requires significant judgment anduncertainties, including assumptions about future taxable income that are based on historical and projected information. The Company recognizes excess taxbenefits when they are realized, as a reduction of the provision for income taxes.The Company assesses its income tax positions and records tax benefits based upon management’s evaluation of the facts, circumstances, and informationavailable at the reporting date. For those tax positions where it is more-likely-than-not that a tax benefit will be sustained, the Company records the largest amountof tax benefit with a greater than 50 percent likelihood of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevantinformation. For those income tax positions where it is not more-likely-than-not that a tax benefit will be sustained, no tax benefit is recognized in the financialstatements. The Company classifies liabilities for uncertain tax positions as non-current liabilities unless the uncertainty is expected to be resolved within one year.The Company classifies interest and penalties on uncertain tax positions as income tax expense.As a global company, the Company uses significant judgment to calculate and provide for income taxes in each of the tax jurisdictions in which it operates. In theordinary course of the Company’s business, there are transactions and calculations undertaken whose ultimate tax outcome cannot be certain. Some of theseuncertainties arise as a consequence of transfer pricing for transactions with the Company’s subsidiaries and nexus and tax credit estimates. In addition, thecalculation of acquired tax attributes and the associated limitations are complex. See "Note 15. Income Taxes" for additional information.Advertising expenseAdvertising costs are expensed as incurred. Advertising costs were $6.9 million , $6.1 million , and $8.9 million during 2018 , 2017 , and 2016 , respectively.41Revenue Standard AdoptedOn January 1, 2018, the Company adopted the ASC 606 revenue recognition standard and has adjusted prior periods to conform to the new standard.The most significant adoption impacts were:•Perpetual licenses with extended payment terms and term licenses - Revenue from perpetual licenses with extended payment terms and term licenses isnow recognized when control is transferred to the client, which is defined as the point in time when the client can use and benefit from the license.Previously, the Company recognized revenue over the term of the agreements as payments became due or earlier if prepaid. Any unrecognized licenserevenue from these arrangements is recognized in the period that control transfers or as a cumulative adjustment to retained earnings as of January 1,2016. Unbilled receivables in the Company’s consolidated balance sheets increased significantly upon adoption due to the revenue from term licensesbeing recognized prior to amounts being due, or prepaid, by clients and perpetual licenses with extended payment terms.•Allocation of future credits and significant discounts - Perpetual and term licenses are a separate performance obligation and the Company is nowrequired to allocate any future credits and discounts to performance obligations in the arrangement based upon their relative stand-alone selling prices,determined using the residual approach.•Deferred contract costs - Sales incentive programs and other incremental costs to obtain a contract were previously expensed when incurred. ASC 340-40requires these costs be recognized as an asset when incurred and expensed over the period of expected benefit, which is on average five years . Thischange primarily impacts the Company’s contracts related to multi-year cloud offerings, maintenance on term and perpetual licenses, and multi-year termand perpetual licenses with client usage rights that increase over time.For additional information on the Company’s accounting policies because of the adoption of ASC 606 and ASC 340-40 see "Note 2.

A modified retrospectivetransition approach is required, applying the new standard to all leases existing at the date of initialapplication. An entity may choose to use either: (1) its effective date or (2) the beginning of the earliestcomparative period presented in the financial statements as its date of initial application.The Company implemented a new lease management system, which included an assessment of the impact ofthe new guidance on the Company’s financial position and results of operation. The Company will use theeffective date as the date of initial application. As part of adoption the Company does not expect to utilizethe hindsight practical expedient but does expect to utilize the package of transition practical expedientsavailable under the standard to not:1. Reassess whether any expired or existing contracts are or contain leases.2. Reassess the lease classification for any expired or existing leases (that is, all existing leases that wereclassified as operating leases in accordance with Topic 840 will be classified as operating leases, and allexisting leases that were classified as capital leases in accordance with Topic 840 will be classified asfinance leases).3. Reassess initial direct costs for any existing leases.On adoption, the Company expects to recognize additional operating liabilities for the Company’s existingoperating leases, principally composed of office leases, that are currently not recognized on the Company’sconsolidated balance sheets with a corresponding right of use assets based on the present value of theremaining minimum rental payments under current leasing standards for existing operating leases. TheCompany does not expect a material impact to its results of operations from adoption. January 1, 2019ASU No. 2016-13, “FinancialInstruments—Credit Losses(Topic 326): Measurement ofCredit Losses on FinancialInstruments” This standard requires the measurement and recognition of expected credit losses for financial assetsmeasured at amortized cost, including trade accounts receivable, upon initial recognition of that financialasset using a forward-looking expected loss model, rather than an incurred loss model for credit losses.Credit losses relating to available-for-sale debt securities should be recorded through an allowance for creditlosses when the fair value is below the amortized cost of the asset, removing the concept of “other-than-temporary” impairments.The Company is currently evaluating the effect this ASU will have on its consolidated financial statementsand related disclosures.

STOCKHOLDERS’ EQUITYPreferred stockThe Company has 1 million authorized shares of preferred stock. The Board of Directors has the authority to issue the shares of preferred stock in one or moreseries, to establish the number of shares to be included in each series, and to determine the designation, powers, preferences, and rights of the shares of each seriesand the qualifications, limitations, or restrictions thereof, without any further vote or action by the stockholders. The issuance of preferred stock could decrease theamount of earnings and assets available for distribution to holders of common stock, and may have the effect of delaying, deferring, or defeating a change incontrol of the Company. The Company had not issued any shares of preferred stock through December 31, 2018 .47Common stockThe Company has 200 million authorized shares of common stock, $0.01 par value per share, of which 78.5 million shares were issued and outstanding atDecember 31, 2018 .Dividends declared (per share)2018 2017 2016Dividends Declared$0.12 $0.12 $0.12Dividend payments(in thousands)2018 2017 2016Dividend payments to shareholders$9,432 $9,277 $9,174It is the Company’s current intention to pay a quarterly cash dividend of $0.03 per share, however, the Board of Directors may terminate or modify this dividendprogram at any time without prior notice.Stock repurchases(in thousands)2018 2017 2016Shares Amount Shares Amount Shares AmountAuthorization remaining, beginning of period $34,892 $39,385 $40,534Authorizations $27,003 $— $25,879Repurchases paid980 $(54,276) 96 $(4,335) 1,078 $(27,028)Repurchases unsettled21 $(999) 3 $(158) — $—Authorization remaining, end of period $6,620 $34,892 $39,385On June 21, 2018, the Company announced that its Board of Directors extended the expiration date of the current stock repurchase program to June 30, 2019 andincreased the amount of common stock the Company is authorized to repurchase to $50 million between June 15, 2018 and June 30, 2019 (the “CurrentProgram”). Under the Current Program, purchases may be made from time to time on the open market or in privately negotiated transactions. Shares may berepurchased in such amounts as market conditions warrant, subject to regulatory and other considerations. The Company has established a pre-arranged stockrepurchase plan, intended to comply with the requirements of Rule 10b5-1 under the Exchange Act, and Rule 10b-18 under the Exchange Act (the “10b5-1 Plan”).All stock repurchases under the Current Program during closed trading window periods will be made pursuant to the 10b5-1 Plan.11. FAIR VALUE MEASUREMENTSAssets and liabilities measured at fair value on a recurring basisThe Company records its cash equivalents, marketable securities, and investments in privately-held companies at fair value on a recurring basis. Fair value is anexit price, representing the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between marketparticipants based on assumptions that market participants would use in pricing an asset or liability.As a basis for classifying the fair value measurements, a three-tier fair value hierarchy, which classifies the fair value measurements based on the inputs used inmeasuring fair value, was established as follows:•Level 1 - observable inputs such as quoted prices in active markets for identical assets or liabilities;•Level 2 - significant other inputs that are observable either directly or indirectly; and•Level 3 - significant unobservable inputs on which there is little or no market data, which require the Company to develop its own assumptions. Thishierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fairvalue.The Company’s cash equivalents are composed of money market funds and time deposits, which are classified within Level 1 and Level 2, respectively, in the fairvalue hierarchy. The Company’s marketable securities, which are classified within Level 2 of the fair value hierarchy, are valued based on a market approach usingquoted prices, when available, or matrix pricing compiled by third party pricing vendors, using observable market inputs such as interest rates, yield curves, andcredit risk. The Company’s investments in privately-held companies are classified within Level 3 of the fair value hierarchy and are valued using model-basedtechniques, including option pricing models and discounted cash flow models.If applicable, the Company will recognize transfers into and out of levels within the fair value hierarchy at the end of the reporting period in which the actual eventor change in circumstance occurs. There were no transfers between levels during 2018 , 2017 , or 2016 .48The Company’s assets and liabilities measured at fair value on a recurring basis were: December 31, 2018(in thousands)Level 1 Level 2 Level 3 TotalCash equivalents$10,155 $10,000 $— $20,155Marketable securities: Municipal bonds$— $44,705 $— $44,705Corporate bonds— 48,296 — 48,296Total marketable securities$— $93,001 $— $93,001Investments in privately-held companies (1)$— $— $3,390 $3,390(1) Included in other long-term assets.

STOCK-BASED COMPENSATIONThe following table presents the stock-based compensation expense included in the Company’s consolidated statements of operations:(in thousands)2018 2017 2016Cost of revenues$16,862 $14,573 $11,459Selling and marketing23,237 15,720 12,464Research and development15,274 13,618 10,043General and administrative8,489 9,402 6,513Acquisition-related— — 342 $63,862 $53,313 $40,821Income tax benefit$(13,383) $(12,113) $(12,198)The Company periodically grants stock options and restricted stock units (“RSUs”) for a fixed number of shares upon vesting to50employees and non-employee Directors.Most of the Company’s stock-based compensation arrangements generally vest over five years with 20% vesting after one year and the remaining 80% vesting inequal quarterly installments over the remaining four years. The Company’s stock options have a ten -year term. The Company recognizes stock-basedcompensation using the accelerated attribution method, treating each vesting tranche as if it were an individual grant. The amount of stock-based compensationrecognized during a period is based on the value of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, ifnecessary, in subsequent periods if actual forfeitures differ from those estimates. Ultimately, the Company recognizes the actual expense over the vesting periodonly for the shares that vest.Employees may elect to receive 50% of their target incentive compensation under the Company’s Corporate Incentive Compensation Plan (the “CICP”) in the formof RSUs instead of cash. If elected by an employee, the equity amount is equal in value on the date of grant to 50% of his or her target incentive opportunity, basedon the employee’s base salary. The number of RSUs granted is determined by dividing 50% of the employee’s target incentive opportunity by 85% of the closingprice of its common stock on the grant date, less the present value of expected dividends during the vesting period. If elected, the award vests 100% on the CICPpayout date of the following year for all participants. Vesting is conditioned upon the performance conditions of the CICP and on continued employment; ifthreshold funding does not occur, the RSUs will not vest. The Company considers vesting to be probable on the grant date and recognizes the associated stock-based compensation expense over the requisite service period beginning, on the grant date and ending on the vesting date.The Company grants awards that allow for the settlement of vested stock options and RSUs on a net share basis (“net settled awards”). With net settled awards, theemployee does not surrender any cash or shares upon exercise. Rather, the Company withholds the number of shares to cover the exercise price (in the case ofstock options) and the minimum statutory tax withholding obligations (in the case of stock options and RSUs) from the shares that would otherwise be issued uponexercise or settlement. The exercise of stock options and settlement of RSUs on a net share basis results in fewer shares issued by the Company.Share-based compensation plans:2004 Long-Term Incentive Plan (as amended and restated)In 2004, the Company adopted the 2004 Long-Term Incentive Plan (as amended and restated, the “2004 Plan”) to provide employees, non-employee Directors, andconsultants with opportunities to purchase stock through incentive stock options and non-qualified stock options. Subsequent amendments to the plan increased thenumber of shares authorized for issuance under the plan to 30 million , extended the term of the plan to 2026, and limited annual compensation to any non-employee Director to $0.5 million .As of December 31, 2018 , approximately 9.6 million shares were subject to outstanding options and stock-based awards under the 2004 Plan.2006 Employee Stock Purchase PlanIn 2006, the Company adopted the 2006 Employee Stock Purchase Plan (the “2006 ESPP”) pursuant to which the Company’s employees are entitled to purchaseup to an aggregate of 1 million shares of common stock, at a price equal to at least 85% of the fair market value of the Company’s common stock on either thecommencement date or completion date for offerings under the plan, whichever is less, or such higher price as the Company’s Board of Directors may establishfrom time to time. Until the Company’s Board of Directors determines otherwise, the Board has set the purchase price at 95% of the fair market value on thecompletion date of the offering period. As a result, the 2006 ESPP is non-compensatory and is tax qualified. Therefore, as of December 31, 2018 , no compensationexpense related to shares issued under the plan had been recognized. In October 2012, the Company’s Board of Directors amended the term of the 2006 ESPP suchthat it will continue until there are no shares remaining to be issued under the plan or until the plan is terminated by the Board of Directors, whichever occurs first.As of December 31, 2018 , approximately 0.4 million shares had been issued thereunder.Shares available for issuanceAs of December 31, 2018 , there were approximately 8.3 million shares available for issuance for future equity grants under the Company’s stock plans, consistingof approximately 7.7 million shares under the 2004 Plan and approximately 0.6 million shares under the 2006 ESPP.Grant activityDuring 2018 , the Company issued approximately 1.4 million shares to its employees and directors under the Company’s share-based compensation plans.Stock optionsThe Company estimates the fair value of stock options using a Black-Scholes option valuation model. Key inputs used to estimate the fair value of stock optionsinclude the exercise price of the award, expected term of the option, expected volatility of the Company’s common stock over the option’s expected term, risk-freeinterest rate over the option’s expected term, and the Company’s expected51annual dividend yield. The exercise price for stock options is greater than or equal to the fair market value of the shares at the grant date.The weighted-average grant-date fair value for stock options granted in 2018 , 2017 , and 2016 , was $18.03 , $13.79 , and $8.31 per share, respectively.The weighted-average assumptions used in the Black-Scholes option valuation model are: 2018 2017 2016Expected annual volatility (1)34% 35% 40%Expected term in years (2)4.5 4.5 4.4Risk-free interest rate (3)2.6% 1.9% 1.2%Expected annual dividend yield (4)0.4% 0.5% 0.6%(1) The expected annual volatility for each grant is determined based on the average of historical daily price changes of the Company’s common stock over a period whichapproximates the expected option term.(2) The expected option term for each grant is determined based on the historical exercise behavior of employees and post-vesting employment termination behavior.(3) The risk-free interest rate is based on the yield of U.S. Treasury securities with a maturity that is commensurate with the expected option term at the time of grant.(4) The expected annual dividend yield is based on the weighted-average of the dividend yield assumptions used for options granted during the applicable period.The following table summarizes the combined stock option activity under the Company’s stock option plans for 2018 : Shares(in thousands) Weighted-averageExercise Price Weighted-averageRemainingContractual Term (inyears) Aggregate IntrinsicValue(in thousands)Options outstanding as of January 1, 20187,130 $26.10 Granted1,705 58.42 Exercised(1,422) 20.88 Forfeited(442) 35.50 Options outstanding as of December 31, 20186,971 $34.47 Vested and expected to vest as December 31, 20185,841 $33.23 7.0 $99,999 Exercisable as of December 31, 20182,893 $22.16 5.7 $74,650The aggregate intrinsic value of stock options exercised (i.e., the difference between the market price at exercise and the price paid by the employee at exercise) in2018 , 2017 , and 2016 was $56.8 million , $62.6 million , and $19.9 million , respectively. The aggregate intrinsic value of stock options outstanding andexercisable as of December 31, 2018 is based on the difference between the closing price of the Company’s stock of $47.83 and the exercise price of the applicablestock options.As of December 31, 2018 , the Company had unrecognized stock-based compensation expense related to the unvested portion of stock options of approximately$21.1 million that is expected to be recognized as expense over a weighted-average period of approximately 2.3 years.RSUsRSUs deliver to the recipient a right to receive a specified number of shares of the Company’s common stock upon vesting. The Company values its RSUs at thefair value of its common stock on the grant date, which is the closing price of its common stock on the grant date, less the present value of expected dividendsduring the vesting period, as the recipient is not entitled to dividends during the requisite service period.52The weighted-average grant-date fair value for RSUs granted in 2018 , 2017 , and 2016 was $58.52 , $46.07 , and $25.54 , respectively.The following table summarizes the combined RSU activity for all grants, including the CICP, under the 2004 Plan for 2018 : Shares (in thousands) Weighted- Average Grant-Date Fair Value Aggregate Intrinsic Value (in thousands)Nonvested as of January 1, 20182,901 $31.97 Granted1,212 58.52 Vested(1,144) 31.88 Forfeited(318) 36.74 Nonvested as of December 31, 20182,651 $43.69 $126,781Expected to vest as of December 31, 20181,938 $44.83 $92,661The fair value of RSUs vested in 2018 , 2017 , and 2016 was $66.5 million , $59.0 million , and $29.2 million , respectively.

The Tax Reform Act makessignificant changes in the U.S. tax code including the following:•reduction of the corporate federal income tax rate from 35% to 21%;•repeal of the domestic manufacturing deduction;•repeal of the corporate alternative minimum tax;•a one-time transition tax on accumulated foreign earnings (if any);•a move to a territorial tax system; and•acceleration of business asset expensing.The Tax Reform Act provided for a one-time deemed mandatory repatriation of post-1986 undistributed foreign subsidiary earnings and profits through December31, 2017. The Company has concluded that it is not be subject to the one-time transition tax due to our foreign subsidiaries being in a net accumulated deficitposition.The Company completed its accounting for the tax effects of enactment of the Tax Reform Act recording a final net benefit amount of $14.2 million pertaining tothe enactment of the Tax Reform Act and the impact of the reduction of the tax rates on our deferred tax attributes; all of which was recorded in 2017 as acomponent of tax expense.Beginning in 2018, the Company was subject to immaterial incremental U.S. tax resulting from global intangible low taxed income (“GILTI”) inclusions.Companies must make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future yearsor to provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. The Company has elected to account for GILTI in theyear the tax is incurred as a period cost.54Deferred income taxesSignificant components of net deferred tax assets and liabilities are: December 31,(in thousands)2018 2017Deferred tax assets: Net operating loss carryforwards$40,736 $52,311Accruals and reserves17,576 14,668Software revenue— —Depreciation2,874 2,558Tax credit carryforwards14,896 13,056Other176 52Total deferred tax assets76,258 82,645Valuation allowances(27,954) (27,994)Total net deferred tax assets48,304 54,651Deferred tax liabilities: Software revenue(36,510) (70,347)Intangibles(5,748) (8,527)Total deferred tax liabilities(42,258) (78,874)Deferred income taxes$6,046 $(24,223)The Company regularly assesses the need for a valuation allowance against its deferred tax assets. In making that assessment, the Company considers both positiveand negative evidence related to the likelihood of realization of the deferred tax assets to determine, based on the weight of available evidence, whether it is more-likely-than-not that some or all of the deferred tax assets will not be realized. This determination requires significant judgment, including assumptions about futuretaxable income that are based on historical and projected information. In 2018, there was no material change in the valuation allowance.At December 31, 2018 the Company’s net operating losses and credit carryforwards are:(in thousands)Federal StateNet operating losses (1)$81,206 $2,210Net operating losses due to acquisitions$81,206 $665Credit carryforwards (2)$7,480 $1,937Credit carryforwards due to acquisitions$640 $324(1) Excludes federal and state net operating losses of $60.2 million and $0.8 million , respectively, and federal and state tax credits of $0.1 million and $7.4 million ,respectively, that the Company expects will expire unutilized,(2) Carryforward losses and credits expire between 2019 and 2037 except for $0.9 million of state credits that have an unlimited carryforward period.At December 31, 2018 , the Company had foreign net operating losses of $46.1 million , all of which the Company expects will expire unutilized.The Company’s India subsidiary is a development center in an area designated as a Special Economic Zone (“SEZ”) and is entitled to a tax holiday in India.

EXECUTIVE COMPENSATIONThe information required by this item is contained in the 2019 proxy statement under the headings “Director Compensation”, “Compensation Discussion andAnalysis”, and “Executive Compensation” and is incorporated herein by reference.ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERSInformation required by this item with respect to stock ownership of certain beneficial owners and management is contained in the 2019 proxy statement under theheading “Security Ownership of Certain Beneficial Owners and Management” and is incorporated herein by reference.Equity Compensation Plan InformationThe following table provides certain information with respect to our equity compensation plans in effect as of December 31, 2018 :(in thousands, except per share amounts)Number of Shares of Common Stock to be Issued Upon Exercise of Outstanding Stock Options and Vesting ofRSUs (3) (4) Weighted-average Exercise price per Share of Outstanding Stock Options (5) Number of Shares ofCommon StockRemaining Availablefor Future Issuance(excluding those incolumn (a)) (6) Equity compensation plans approved bystockholders (1)9,621 $34.47 8,250Equity compensation plans not approved bystockholders (2)1 $13.81 —(1) We currently maintain two equity compensation plans: the 2004 Long-Term Incentive Plan as amended and restated, the (“2004 Plan”) and the 2006 Employee StockPurchase Plan as amended (“2006 ESPP”). In addition to the issuance of stock options, the 2004 Plan allows for the issuance of stock purchase rights and other stock-basedawards, including RSUs. Our stockholders previously approved each of these plans and all amendments that were subject to stockholder approval. See "13. Stock-BasedCompensation" in Item 8 of this Annual Report for additional information.(2) These stock options were assumed in connection with our acquisition of Chordiant in 2010 and were originally granted under the Chordiant Software, Inc. 2005 EquityIncentive Plan (“2005 Plan”). No additional awards were or may be granted under the 2005 Plan following the date of acquisition. This plan was not approved by ourstockholders since it was adopted on the date of acquisition. In connection with our acquisition of Chordiant, all outstanding equity awards issued under the 2005 Plan withan exercise price of $3.00, on a post-split basis, or lower were assumed by us and converted into the right to receive 0.13 shares of Pegasystems common stock for everyshare of Chordiant common stock covered by such awards. All other outstanding equity awards issued under the 2005 Plan were cancelled. The 2005 Plan was approved byChordiant’s stockholders and provided for the grant of incentive stock options, nonstatutory stock options, stock purchase awards, RSAs, RSUs, and other forms of equitycompensation. Awards granted under the 2005 Plan generally expire four to ten years after the grant date and generally become exercisable over a period of two to fouryears, with either yearly or monthly vesting.(3) The number of shares of common stock issued upon exercise of vested stock options and vesting of RSUs will be less than the 9.6 million shown above because of the “netsettlement” feature of most of these stock options and RSUs. This feature enables the Company to withhold shares to cover the cost to exercise stock options and, ifapplicable, to cover taxes due (in the case of stock options and RSUs) based on the fair value of the shares at the exercise date (in the case of stock options) or vesting date(in the case of RSUs), instead of selling all of the shares on the open market to satisfy these obligations. The settlement of exercised stock options and vested RSUs on a netshare basis will result in fewer shares issued by the Company.(4) During 2018 , stock option and RSU holders net settled stock options and RSUs representing the right to purchase a total of 2.5 million shares, of which only 1.4 millionwere issued to the stock option and RSU holders, and the balance of the shares were surrendered to the Company to pay for the exercise price (in the case of stock options)and the applicable taxes (in the case of stock options and RSUs).(5) The weighted-average exercise price does not consider the shares issuable upon vesting of outstanding RSUs, which have no exercise price.(6) Includes approximately 0.6 million shares remaining available for issuance as of December 31, 2018 under the 2006 ESPP.ITEM 13.
