As a result, we have established long-term relationships with many of our clients who continueto engage us for additional projects and serve as references for us.

We have built meaningful relationships with software providers, whose products we use to design andimplement solutions for our clients. These relationships enable us to reduce our cost of sales and sales cycle times and increase win rates byleveraging our partners’ marketing efforts and endorsements. We also serve as a sales channel for our partners, helping them market and sell theirsoftware products. We are an IBM Premier Business Partner, a Microsoft National Solutions Provider and Global NSP Partner, an OraclePlatinum Partner, an Adobe Premium Partner, and a Salesforce Platinum Consulting Partner.

As of December 31, 2017, we had 47 colleagues at the DDC.CompetitionThe market for the services we provide is competitive and has low barriers to entry. We believe that our competitors fall into several categories,including:•small local consulting firms that operate in no more than one or two geographic regions;•boutique consulting firms, such as Prolifics and Avanade;•national consulting firms, such as Accenture, Deloitte Consulting, Publicis.Sapient, EPAM Systems, and Globant;•digital consulting firms/entities such as Accenture Interactive, Deloitte Digital, SapientRazorfish, Edgewater, and Computer Task Group;•in-house professional services organizations of software companies; and•offshore providers, such as Infosys Technologies Limited, Cognizant and Wipro Limited.4 We believe that the principal competitive factors affecting our market include domain expertise, track record and customer references, partnernetwork with leading technology companies, quality of proposed solutions, service quality and performance, efficiency, reliability, scalability and features ofthe software platforms upon which the solutions are based, and the ability to implement solutions quickly and respond on a timely basis to customer needs. Inaddition, because of the relatively low barriers to entry into this market, we expect to face additional competition from new entrants. We expect competitionfrom offshore outsourcing and development companies to continue.Some of our competitors have longer operating histories, larger client bases, greater name recognition, and possess significantly greater financial,technical, and marketing resources than we do. As a result, these competitors may be able to attract customers to which we market our services and adapt morequickly to new technologies or evolving customer or industry requirements.EmployeesAs of December 31, 2017, we had 3,024 employees, 2,362 of which were billable (excluding 216 billable subcontractors) and 446 of which wereinvolved in sales, administration, and marketing.

Our direct sales force works in tandem with the sales and marketing groups of our partners to identify potential new clients andprojects. Our partnerships with these companies enable us to reduce our cost of sales and sales cycle times and increase win rates by leveraging our partners’marketing efforts and endorsements.Talent Acquisition.

We makeavailable free of charge through our website our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendmentsto those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as soon asreasonably practicable after we electronically file such material with, or furnish it to, the SEC. The information contained or incorporated in our website is notpart of this document.Financial Information about Segments and Geographic AreasSee the Consolidated Financial Statements and the Notes to Consolidated Financial Statements appearing in Part II, Item 8.5 Item 1A.Risk Factors.You should carefully consider the following factors together with the other information contained in or incorporated by reference into this AnnualReport on Form 10-K before you decide to buy our common stock. These factors could materially adversely affect our business, financial condition,operating results, cash flows, or stock price. Our business is also subject to general risks and uncertainties that may broadly affect companies, including us.Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also could materially adversely affect our business,financial condition, operating results, cash flows, or stock price.Our results of operations could be adversely affected by volatile, negative or uncertain economic conditions and the effects of these conditions on ourclients’ businesses and levels of business activity.Global macroeconomic conditions affect our clients’ businesses and the markets they serve. Developments such as economic downturns, recessions,instability and inflationary risks in the United States, Europe, Canada, China and India, among other developments, may have an adverse effect on ourclients’ businesses and, consequently, on our results of operations, revenue growth and profitability.Volatile, negative or uncertain economic conditions in the markets we serve have undermined, and could in the future undermine, businessconfidence and cause our clients to reduce or defer their spending on new technologies or initiatives or terminate existing contracts, which would negativelyaffect our business. Growth in markets we serve could be at a slow rate, or could stagnate, in each case, for an extended period of time. Differing economicconditions and patterns of economic growth and contraction in the geographical regions in which we operate and the markets we serve have affected, andmay in the future affect, demand for our services. A material portion of our revenues and profitability is derived from our clients in North America. Weakeningdemand in this market could have a material adverse effect on our results of operations. Ongoing economic volatility and uncertainty affects our business in anumber of other ways, including making it more difficult to accurately forecast client demand beyond the short term and effectively build our revenue andresource plans, particularly in consulting. This could result, for example, in us not having the level of appropriate personnel where they are needed or havingto use involuntary terminations as means to keep our supply of skills and resources in balance.Economic volatility and uncertainty is particularly challenging because it may take some time for the effects and resulting changes in demandpatterns to manifest themselves in our business and results of operations. Changing demand patterns from economic volatility and uncertainty could have asignificant negative impact on our results of operations.We face risks associated with potential changes to federal, state, local and foreign laws, regulations and policies.Significant changes to various federal, state, local and foreign laws, regulations and policies to which the Company is subject are underconsideration by applicable government administrations and agencies. If enacted, these changes may affect our business in a manner that currently cannot bereliably predicted. These uncertainties may include changes in laws, regulations and policies in areas such as corporate taxation (including but not limited tothe recently enacted Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”)), international trade, labor and employment law, immigration and health care,which individually or in the aggregate could materially and adversely affect our business, results of operations or financial condition.We provide services to various clients participating in the healthcare market. Certain cuts in U.S. government healthcare programs and other changeshave been proposed and discussed. These cuts and changes may result in reduced expenditures by our healthcare customers on information technologyprojects, which could materially and adversely affect our business, results of operations or financial condition.Our business depends on generating and maintaining ongoing, profitable client demand for our services and solutions, and a significant reduction insuch demand could materially affect our results of operations.Our revenue and profitability depend on the demand for our services and favorable margins, which could be negatively affected by numerousfactors, many of which are beyond our control and unrelated to our work product. As described above, volatile, negative or uncertain global economicconditions have adversely affected, and could in the future adversely affect, client demand for our services and solutions. In addition, developments in themarkets we serve, which may be rapid, could shift demand to services and solutions where we are less competitive, or might require significant investment byus to upgrade, enhance or expand our services and solutions to meet that demand. Companies in the markets we serve sometimes seek to achieve economiesof scale and other synergies by combining with or acquiring other companies. If one of our current clients merges or consolidates with a company that relieson another provider for its consulting, systems integration and technology, or outsourcing services, we may lose work from that client or lose the opportunityto gain additional work if we are not successful in generating new opportunities from the merger or consolidation. Many of our consulting contracts are lessthan 12 months in duration, and often contain 10 to 30 day termination provisions. If a client is dissatisfied with our services and we are unable to effectivelyrespond to its needs, the client might terminate existing contracts, or reduce or eliminate spending on the services and solutions we provide. Additionally, aclient could choose not to retain us for additional stages of a project, try to renegotiate the terms of its contract or cancel or delay additional planned work.When contracts are terminated or not renewed, we lose the anticipated revenues, and it may take significant time to replace the lost revenues or we may beunsuccessful in our attempt to recover such revenues. Consequently, our results of operations in subsequent periods could be materially lower than expected.The specific business or financial condition of a client, changes in management and changes in a client’s strategy also are all factors that can result interminations, cancellations or delays. It could also result in pressure to reduce the cost of our services.6 If we are unable to keep our supply of skills and resources in balance with client demand and attract and retain professionals with strong leadershipskills, our business, the utilization rate of our professionals and our results of operations may be materially adversely affected.Our success depends, in large part, upon our ability to keep our supply of skills and resources in balance with client demand and our ability to attractand retain personnel with the knowledge and skills to lead our business. Experienced personnel in our industry are in high demand, and there is muchcompetition to attract qualified personnel. We must hire, retain and motivate appropriate numbers of talented people with diverse skills in order to serveclients across North America, respond quickly to rapid and ongoing technology, industry and macroeconomic developments and grow and manage ourbusiness. For example, if we are unable to hire or continually train our employees to keep pace with the rapid and continuing changes in technology and themarkets we serve or changes in the types of services clients are demanding we may not be able to develop and deliver new services and solutions to fulfillclient demand. As we expand our services and solutions, we must also hire and retain an increasing number of professionals with different skills andexpectations than those of the professionals we have historically hired and retained. Additionally, if we are unable to successfully integrate, motivate andretain these professionals, our ability to continue to secure work for our services and solutions in those markets may decline.We are dependent upon retaining our senior executives and other experienced managers, and if we are unable to do so, our ability to develop newbusiness and effectively lead our current projects could be jeopardized. We depend upon identifying, developing, and retaining key employees to provideleadership and direction for our businesses. This includes developing talent and leadership capabilities in emerging markets, where the depth of skilledemployees is often limited and competition for these resources is great. Our geographic expansion strategy in emerging markets depends on our ability toattract, retain and integrate both local business leaders and people with the appropriate skills.Similarly, our profitability depends upon our ability to effectively utilize personnel with the right mix of skills and experience to perform servicesfor our clients, including our ability to transition employees to new assignments on a timely basis. If we are unable to effectively deploy our employees on atimely basis to fulfill the needs of our clients, our ability to perform our work profitably could suffer. If the utilization rate of our professionals is too high, itcould have an adverse effect on employee engagement and attrition, the quality of the work performed and our ability to staff projects. If our utilization rateis too low, our profitability and the engagement of our employees could suffer. The costs associated with recruiting and training employees are significant.An important element of our global business model is the deployment of our employees around the world, which allows us to move talent as needed.Therefore, if we are not able to deploy the talent we need because of increased regulation of immigration or work visas, including limitations placed on thenumber of visas granted, limitations on the type of work performed or location in which it can be performed, and new or higher minimum salary requirements,it could be more difficult to staff our employees on client engagements and could increase our costs.Our equity-based incentive compensation plans are designed to reward high-performing personnel for their contributions and provide incentives forthem to remain with us. If the anticipated value of these incentives does not materialize because of volatility or lack of positive performance in our stockprice, or if our total compensation package is not viewed as being competitive, our ability to attract and retain the personnel we need could be adverselyaffected.There is a risk that at certain points in time and in certain markets, we will find it difficult to hire and retain a sufficient number of employees withthe skills or backgrounds to meet current and/or future demand. In these cases, we might need to redeploy existing personnel or increase our reliance onsubcontractors to fill certain labor needs, and if not done effectively, our profitability could be negatively impacted. Additionally, if demand for our serviceswere to escalate at a high rate, we may need to adjust our compensation practices, which could put upward pressure on our costs and adversely affect ourprofitability if we are unable to recover these increased costs. At certain times, however, we may also have more personnel than we need in certain skill sets orgeographies. In these situations, we must evaluate voluntary attrition and use reduced levels of new hiring and increased involuntary terminations as meansto keep our supply of skills and resources in balance with client demand in those markets.The market for the information technology consulting services in which we operate is highly competitive, and we might not be able to competeeffectively.The market for the information technology consulting services we provide is competitive, ever evolving, and subject to rapid technological change.Our competitors include: large multinational providers that offer some or all of the services that we do; offshore service providers in lower-cost locations thatoffer services similar to those we offer, often at highly competitive prices and on more aggressive contractual terms; niche solution and service providers orlocal competitors that compete with us in a specific geographic market, industry segment or service area, including companies that provide new or alternativeproducts, service or delivery models; accounting firms that are expanding or building their capabilities to provide certain consulting services, includingthrough acquisitions; and in-house departments of large corporations that use their own resources, rather than engage an outside firm for the types of serviceswe provide.Many of the larger regional and national information technology consulting firms have substantially longer operating histories, more establishedreputations and potential vendor relationships, greater financial resources, sales and marketing organizations, market penetration, and research anddevelopment capabilities, as well as broader product offerings, greater market presence, and name recognition.In addition, there are relatively low barriers to entry into this market and therefore new entrants may compete with us in the future. For example, dueto the rapid changes and volatility in our market, many well-capitalized companies, including some of our partners that have focused on sectors of thesoftware and services industry that are not competitive with our business may refocus their activities and deploy their resources to be competitive with us.Our future financial performance is largely dependent upon our ability to compete successfully in the markets we currently serve. If we are unable tocompete successfully, we could lose market share and clients to competitors, which could materially adversely affect our results of operations.In addition, we may face greater competition due to consolidation of companies in the technology sector, through strategic mergers or acquisition.Consolidation activity may result in new competitors with greater scale, a broader footprint, or offerings that are more attractive than ours. We believe thatthis competition could have a negative effect on our ability to compete for new work and skilled professionals. One or more of our competitors may developand implement methodologies that result in superior productivity and price reductions without adversely affecting their profit margins. In addition,competitors may win client engagements by significantly discounting their services in exchange for a client’s promise to purchase other goods and servicesfrom the competitor, either concurrently or in the future. These activities may potentially force us to lower our prices and suffer reduced operating margins.Any of these negative effects could significantly impair our results of operations and financial condition. We may not be able to compete successfully againstnew or existing competitors.7 We could have liability or our reputation could be damaged if we fail to protect client and Company data or information systems or if our informationsystems are breached.We are dependent upon information technology networks and systems to process, transmit, and store electronic information and to communicateamong our locations and with our partners and clients. Security breaches of this infrastructure could lead to shutdowns or disruptions of our systems andpotential unauthorized disclosure of confidential information. In providing services to clients, we are also required at times to manage, utilize, and storesensitive or confidential client or employee data. As a result, we are subject to numerous laws and regulations designed to protect this information, such asvarious U.S. federal and state laws and foreign laws governing the protection of personally identifiable information. If any person, including any of ouremployees, negligently disregards or intentionally breaches our established controls with respect to such data or otherwise mismanages or misappropriatesthat data, we could be subject to monetary damages, regulatory enforcement actions, fines, and/or criminal prosecution. Unauthorized disclosure of sensitiveor confidential client or employee data, whether through systems failure, employee negligence, fraud or misappropriation could damage our reputation andcause us to lose clients. Similarly, unauthorized access to or through our information systems or those we develop for our clients, whether by our employeesor third parties, could result in negative publicity, significant remediation costs, legal liability, and damage to our reputation and could have a materialadverse effect on our results of operations. In addition, our liability insurance might not be sufficient in type or amount to cover us against claims related tosecurity breaches, cyber-attacks and other related breaches.We might not be successful at identifying, acquiring, or integrating other businesses.We have pursued a disciplined acquisition strategy designed to enhance or add to our offerings of services and solutions, or to enable us to expandin certain markets. Depending upon the opportunities available, we may increase our investment in these acquisitions. In that pursuit, we may notsuccessfully identify suitable acquisition candidates, succeed in completing targeted transactions, or achieve desired results of operations. Furthermore, weface risks in successfully integrating any businesses we acquire. Ongoing business may be disrupted and our management’s attention may be diverted byacquisitions, transition or integration activities. In addition, we might need to dedicate additional management and other resources, and our organizationalstructure could make it difficult for us to efficiently integrate acquired businesses into our ongoing operations and assimilate and retain employees of thosebusinesses into our culture and operations.We might fail to realize the expected benefits or strategic objectives of any acquisition we make. We might not achieve our expected return oninvestment, or we may lose money. We may be adversely impacted by liabilities that we assume from a company we acquire, including from that company’sknown and unknown obligations, intellectual property or other assets, terminated employees, current or former clients, or other third parties, and we may failto identify or adequately assess the magnitude of certain liabilities, shortcomings or other circumstances prior to acquisition, which could result inunexpected legal or regulatory exposure, unexpected increases in taxes or other adverse effects on our business and profitability. If we are unable to completethe number and kind of acquisitions for which we plan, or if we are inefficient or unsuccessful at integrating any acquired businesses into our operations, wemay not be able to achieve our planned rates of growth or improve our market share, profitability, or competitive position in specific markets or services.International operations subject us to additional political and economic risks that could have an adverse impact on our business.We maintain global development centers in India and China. We have offices in the United Kingdom and Canada. We are subject to certain risksrelated to expanding our presence into non-U.S. regions, including risks related to complying with a wide variety of national and local laws, restrictions onthe import and export of certain technologies, and multiple and possibly overlapping tax structures. In addition, we may face competition from companiesthat may have more experience with operations in these countries or with international operations generally. We may also face difficulties integrating newfacilities in different countries into our existing operations, as well as integrating employees that we hire in different countries into our existing corporateculture.Furthermore, there are risks inherent in operating in and expanding into non-U.S. regions, including, but not limited to:•political and economic instability, including in connection with the United Kingdom’s exit from the European Union;•global health conditions and potential natural disasters;•unexpected changes in regulatory requirements, including immigration restrictions, tariffs, and other trade barriers and tax regulations, theenforcement of such requirements by applicable governmental authorities and other legal uncertainty;•limitations on our ability to repatriate cash from our international operations;•complexities and additional costs in effectively managing our international operations;•international currency controls and exchange rate fluctuations;•reduced protection for intellectual property rights; and•additional vulnerability from terrorist groups targeting U.S. interests abroad.Any one or more of the factors set forth above could have a material adverse effect on our international operations and, consequently, on ourbusiness, financial condition, and operating results.Immigration restrictions related to H1-B visas could hinder our growth and adversely affect our business, financial condition and results of operations.Approximately 9% of our billable workforce is comprised of skilled foreign nationals holding H1-B visas. We also operate recruiting anddevelopment facilities in India and China to continue to grow our base of H1-B foreign national colleagues. The H1-B visa classification enables us to hirequalified foreign workers in positions that require the equivalent of at least a bachelor’s degree in the U.S. in a specialty occupation such as technologysystems engineering and analysis. The H1-B visa generally permits an individual to work and live in the U.S. for a period of three to six years, with someextensions available. The number of new H1-B petitions approved in any federal fiscal year is limited, making the H1-B visas necessary to bring foreignemployees to the U.S. unobtainable in years in which the limit is reached. The number of H1-B visas available, and the process to obtain them, may besubject to significant change in connection with the change in administrations in the U.S. federal government. If we are unable to obtain all of the H1-B visasfor which we apply, our growth may be hindered.8 Our results of operations could materially suffer if we are not able to obtain favorable pricing.If we are not able to obtain favorable pricing for our services, our revenues and profitability could materially suffer. The rates we are able to chargefor our services are affected by a number of factors, including, but not limited to:•general economic and political conditions;•the competitive environment in our industry, as described below;•our clients’ desire to reduce their costs;•our ability to accurately estimate, attain, and sustain contract revenues, margins, and cash flows over the full contract period; and•procurement practices of clients and their use of third-party advisors.The competitive environment in our industry affects our ability to obtain favorable pricing in a number of ways, any of which could have a materialnegative impact on our results of operations. The less we are able to differentiate our services and solutions and/or clearly convey the value of our servicesand solutions, the more risk we have that they will be seen as commodities, with price being the driving factor in selecting a service provider. In addition, theintroduction of new services or products by competitors could reduce our ability to obtain favorable pricing for the services or products we offer. Competitorsmay be willing, at times, to price contracts lower than us in an effort to enter the market or increase market share. Further, if competitors develop andimplement methodologies that yield greater efficiency and productivity, they may be better positioned to offer services similar to ours at lower prices.If our negotiated fees do not accurately anticipate the cost and complexity of performing our work, then our contracts could be unprofitable.We negotiate fees with our clients by utilizing a range of pricing structures and conditions, including time and materials and fixed fee contracts. Ourfees are highly dependent upon our internal forecasts and predictions about the level of effort and cost necessary to deliver such services and solutions, whichmight be based on limited data and could turn out to be materially inaccurate. If we do not accurately estimate the level of effort or cost, our contracts couldyield lower profit margins than planned, or be unprofitable. We could face greater risk when negotiating fees for our contracts that involve the coordinationof operations and workforces in multiple locations and/or utilizing workforces with different skill sets and competencies. There is a risk that we willunderprice our contracts, fail to accurately estimate the costs of performing the work, or fail to accurately assess the risks associated with potential contracts.In particular, any increased or unexpected costs, delays or failures to achieve anticipated cost savings, or unexpected risks we encounter in connection withthe performance of services, including those caused by factors outside our control, could make these contracts less profitable or unprofitable, which couldhave an adverse effect on our profit margin.Our business could be materially adversely affected if we incur legal liability in connection with providing our services and solutions.We could be subject to significant legal liability and litigation expense if we fail to meet our contractual obligations, or otherwise breachobligations, to third parties, including clients, partners, employees and former employees, and other parties with whom we conduct business, or if oursubcontractors breach or dispute the terms of our agreements with them and impede our ability to meet our obligations to our clients. We may enter intoagreements with non-standard terms because we perceive an important economic opportunity or because our personnel did not adequately follow ourcontracting guidelines. In addition, the contracting practices of competitors, along with the demands of increasingly sophisticated clients, may cause contractterms and conditions that are unfavorable to us to become new standards in the marketplace. We may find ourselves committed to providing services orsolutions that we are unable to deliver or whose delivery will reduce our profitability or cause us financial loss. If we cannot or do not meet our contractualobligations and if our potential liability is not adequately limited through the terms of our agreements, liability limitations are not enforced or a third partyalleges fraud or other wrongdoing to prevent us from relying upon those contractual protections, we might face significant legal liability and litigationexpense and our results of operations could be materially adversely affected. A failure of a client’s system based on our services or solutions could alsosubject us to a claim for significant damages that could materially adversely affect our results of operations. In addition to expense, litigation can be lengthyand disruptive to normal business operations, and litigation results can be unpredictable. While we maintain insurance for certain potential liabilities, thisinsurance does not cover all types and amounts of potential liabilities and is subject to various exclusions as well as caps on amounts recoverable. Even if webelieve a claim is covered by insurance, insurers may dispute our entitlement to recovery for a variety of potential reasons, which may affect the timing andthe amount of our recovery, if any.Our results of operations and ability to grow could be materially negatively affected if we cannot adapt and expand our services and solutions inresponse to ongoing changes in technology and offerings by new entrants.Our success depends upon our ability to continue to develop and implement services and solutions that anticipate and respond to rapid andcontinuing changes in technology and industry developments and offerings by new entrants to serve the evolving needs of our clients. Current areas ofsignificant change include mobility, cloud-based computing, software as a service solutions and the processing and analyzing of large amounts of data.Technological developments such as these may materially affect the cost and use of technology by our clients. Our growth strategy focuses on responding tothese types of developments by driving innovation for our core business as well as through new business initiatives beyond our core business that will enableus to differentiate our services and solutions. If we do not sufficiently invest in new technology and industry developments, or if we do not make the rightstrategic investments to respond to these developments and successfully drive innovation, our services and solutions, our results of operations, and ourability to develop and maintain a competitive advantage and continue to grow could be negatively affected.In addition, we operate in a quickly evolving environment, in which there currently are, and we expect will continue to be, new technology entrants.New services or technologies offered by competitors or new entrants may make our offerings less differentiated or less competitive, when compared to otheralternatives, which may adversely affect our results of operations.The loss of one or more of our significant software vendors could have a material and adverse effect on our business and results of operations.We have significant relationships with software vendors including IBM, Oracle, Microsoft, Salesforce, Adobe and Magento. Our businessrelationships with these companies enable us to reduce our cost of acquiring customers and increase win rates through leveraging our vendors’ marketingefforts and strong vendor endorsements. The loss of one or more of these relationships and endorsements could increase our sales and marketing costs, lead tolonger sales cycles, harm our reputation and brand recognition, reduce our revenues, and adversely affect our results of operations. The financial impact ofthe loss of one or more software vendors is not reasonably estimable. Our services could infringe upon the intellectual property rights of others.We cannot be sure that our services do not infringe on the intellectual property rights of third parties, and we could have infringement claims asserted against us. These claims may harm our reputation, cause our management to expend significant time in connection with any defense, and cost usmoney. We may be required to indemnify clients for any expense or liabilities they incur resulting from claimed infringement and these expenses couldexceed the amounts paid to us by the client for services we have performed. Any claims in this area, even if won by us, could be costly, time-consuming, andharmful to our reputation.9 We have only a limited ability to protect our intellectual property rights, which are important to our success.Our success depends, in part, upon our ability to protect our proprietary methodologies and other intellectual property. Existing laws of somecountries in which we provide services or solutions might offer only limited protection of our intellectual property rights. We rely upon a combination oftrade secrets, confidentiality policies, nondisclosure, and other contractual arrangements to protect our intellectual property rights. These laws are subject tochange at any time and could further restrict our ability to protect our innovations. Our intellectual property rights may not prevent competitors fromindependently developing products and services similar to or duplicative of ours. Further, the steps we take in this regard might not be adequate to prevent ordeter infringement or other misappropriation of our intellectual property by competitors, former employees or other third parties, and we might not be able todetect unauthorized use of, or take appropriate and timely steps to enforce, our intellectual property rights. Enforcing our rights might also requireconsiderable time, money and oversight and we may not be successful in enforcing our rights.Depending upon the circumstances, we might need to grant a specific client greater rights in intellectual property developed in connection with acontract than we otherwise generally do. In certain situations, we might forego rights to the use of intellectual property we help create or knowledgeassociated with such creation, which would limit our ability to reuse that intellectual property or knowledge for other clients. Any limitation on our ability toprovide a service or solution could cause us to lose revenue-generating opportunities and require us to incur additional expenses to develop new or modifiedsolutions for future projects.Our ability to attract and retain business may depend upon our reputation in the marketplace.We believe the Perficient brand name and our reputation are important corporate assets that help distinguish our services from those of ourcompetitors and also contribute to our efforts to recruit and retain talented employees. However, our corporate reputation is potentially susceptible tomaterial damage by events such as disputes with clients, information technology security breaches or service outages, or other delivery failures. Similarly, ourreputation could be damaged by actions or statements of current or former clients, employees, competitors, vendors, as well as members of the investmentcommunity and the media. There is a risk that negative information could adversely affect our business. Damage to our reputation could be difficult and time-consuming to repair, could make potential or existing clients reluctant to select us for new engagements or cause existing clients to terminate our services,resulting in a loss of business, and could adversely affect our recruitment and retention efforts. Damage to our reputation could also reduce the value andeffectiveness of the Perficient brand name and could reduce investor confidence in us, materially adversely affecting our share price.Our profitability could suffer if our cost-management strategies are unsuccessful.Our ability to improve or maintain our profitability is dependent upon our ability to successfully manage our costs. Our cost management strategiesinclude maintaining appropriate alignment between the demand for our services and our resource capacity, optimizing the costs of service delivery andmaintaining or improving our sales and marketing and general and administrative costs as a percentage of revenues. These actions and other cost-management efforts may not be successful, our efficiency may not be enhanced and we may not achieve desired levels of profitability. Because of thesignificant steps taken in the past to reduce costs, we may not be able to continue to deliver efficiencies in our cost management, to the same degree as in thepast. If we are not effective in reducing our operating costs in response to changes in demand or pricing, we might not be able to manage significantly largerand more diverse workforces as we increase the number of colleagues and execute our growth strategy, control our costs or improve our efficiency, and ourprofitability could be negatively affected.We make estimates and assumptions in connection with the preparation of our consolidated financial statements, and any changes to those estimates andassumptions could adversely affect our financial results.Our financial statements have been prepared in accordance with U.S. generally accepted accounting principles. The application of these principlesrequires us to make estimates and assumptions about certain items and future events that affect our reported financial condition, and our accompanyingdisclosure with respect to, among other things, revenue recognition, purchase accounting related fair value measurements, contingent consideration andincome taxes. We base our estimates on historical experience, contractual commitments and on various other assumptions that we believe to be reasonableunder the circumstances at the time they are made. These estimates and assumptions involve the use of our judgment and can be subject to significantuncertainties, some of which are beyond our control. If our estimates, or the assumptions underlying such estimates, are not correct, actual results may differmaterially from our estimates, and we may need to, among other things, adjust revenues or accrue additional charges that could adversely affect our results ofoperations.Our results of operations and share price could be adversely affected if we are unable to maintain effective internal controls.The accuracy of our financial reporting is dependent on the effectiveness of our internal controls. We are required to provide a report frommanagement to our stockholders on our internal control over financial reporting that includes an assessment of the effectiveness of these controls. Internalcontrol over financial reporting has inherent limitations, including human error, the possibility that controls could be circumvented or become inadequatebecause of changed conditions, and fraud. Because of these inherent limitations, internal control over financial reporting might not prevent or detect allmisstatements or fraud. If we cannot maintain and execute adequate internal control over financial reporting or implement required new or improved controlsthat provide reasonable assurance of the reliability of the financial reporting and preparation of our financial statements for external use, we could suffer harmto our reputation, fail to meet our public reporting requirements on a timely basis, be unable to properly report on our business and our results of operations,or be required to restate our financial statements, and our results of operations, our share price and our ability to obtain new business could be materiallyadversely affected.10 Changes in our level of taxes, audits, investigations and tax proceedings, or changes in tax laws or their interpretation or enforcement could have amaterial adverse effect on our results of operations and financial condition.We are subject to income taxes in numerous jurisdictions. We calculate and provide for income taxes in each tax jurisdiction in which we operate.Tax accounting often involves complex matters and requires our judgment to determine our corporate provision for income taxes and other tax liabilities. Weare subject to ongoing tax audits in various jurisdictions. Tax authorities have disagreed, and may in the future disagree, with our judgments, or may takeincreasingly aggressive positions opposing the judgments we make. We regularly assess the likely outcomes of these audits to determine the appropriatenessof our tax liabilities. However, our judgments might not be sustained as a result of these audits, and the amounts ultimately paid could be different from theamounts previously recorded. See Note 10, Income Taxes, in the Notes to the Consolidated Financial Statements for additional information regarding thedisallowance of certain research credits claimed by the Company and the Company’s actions to assert such credits. In addition, our effective tax rate in thefuture could be adversely affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred taxassets and liabilities and changes in tax laws. Tax rates in the jurisdictions in which we operate may change as a result of macroeconomic or other factorsoutside of our control. Increases in the tax rate in any of the jurisdictions in which we operate could have a negative impact on our profitability. In addition,changes in tax laws (particularly the 2017 Tax Act signed into law on December 22, 2017), treaties, or regulations, or their interpretation or enforcement, maybe unpredictable and could materially adversely affect our tax position. This legislation will make significant changes to the U.S. Internal Revenue Code.Such changes include a reduction in the corporate tax rate, limitations on certain corporate deductions and credits, and a one-time repatriation tax on deemedrepatriation of historical earnings of foreign subsidiaries among other changes. The changes included in the 2017 Tax Act are broad and complex. The finaltransition impacts of the 2017 Tax Act may differ from the Company’s estimates, possibly materially, due to, among other things, changes in interpretationsof the 2017 Tax Act, any legislative actions to address questions that arise because of the 2017 Tax Act, any changes in the accounting standards for incometaxes or related interpretations in response to the 2017 Tax Act, or any updates or changes to estimates the Company has utilized to calculate the transitionimpacts, including impacts from changes to current year earnings estimates and foreign exchange rates of foreign subsidiaries. Certain of these changes couldhave a negative impact on our business. Additionally, adverse changes in the underlying profitability and financial outlook of our operations or changes intax law could lead to changes in our valuation allowances against deferred tax assets on our consolidated balance sheets, which could materially affect ourresults of operations. Any of these occurrences could have a material adverse effect on our results of operations and financial condition. See Note 10, IncomeTaxes, in the Notes to the Consolidated Financial Statements for additional information regarding the 2017 Tax Act.Our results of operations could be adversely affected by fluctuations in foreign currency exchange rates.Although we report our results of operations in U.S. dollars, a small portion of our revenues is denominated in currencies other than the U.S. dollar.Unfavorable fluctuations in foreign currency exchange rates could have an adverse effect on our results of operations.Because our consolidated financial statements are presented in U.S. dollars, we must translate revenues and expenses, as well as assets and liabilities,into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, changes in the value of the U.S. dollar against othercurrencies will affect our net revenues, operating income and the value of balance-sheet items, including intercompany payables and receivables,denominated in other currencies. These changes cause our growth in consolidated earnings stated in U.S. dollars to be higher or lower than our growth inlocal currency when compared against other periods. Our currency hedging program, which is designed to partially offset the impact on consolidatedearnings related to the changes in value of certain balance sheet items, might not be successful.As we continue to leverage our global delivery model, certain of our expenses are incurred in currencies other than those in which we bill for therelated services. An increase in the value of certain currencies, such as the Indian Rupee, Chinese Yuan, Canadian dollar, British Pound and Euro, against theU.S. dollar could increase costs for delivery of services at off-shore sites by increasing labor and other costs that are denominated in local currency. Ourcontractual provisions or cost management efforts might not be able to offset their impact, and our currency hedging activities, which are designed topartially offset this impact, might not be successful. This could result in a decrease in the profitability of our contracts that are utilizing delivery centerresources. Conversely, a decrease in the value of certain currencies, such as the Canadian dollar, Indian Rupee, Chinese Yuan, British Pound and Euro,against the U.S. dollar in which our revenue is recorded could place us at a competitive disadvantage compared to service providers that benefit to a greaterdegree from such a decrease and can, as a result, deliver services at a lower cost. In addition, our currency hedging activities are themselves subject to risk.These include risks related to counterparty performance under hedging contracts, risks related to ineffective hedges and risks related to currency fluctuations.We also face risks that extreme economic conditions, political instability, hostilities or natural disasters could impact or perhaps eliminate the underlyingexposures that we are hedging. Such an event could lead to losses being recognized on the currency hedges then in place that are not offset by anticipatedchanges in the underlying hedge exposure.If we do not effectively manage expected future growth, our results of operations and cash flows could be adversely affected.Our ability to operate profitably with positive cash flows depends partially upon how effectively we manage our expected future growth. In order tocreate the additional capacity necessary to accommodate an increase in demand for our services, we may need to implement new or upgraded operational andfinancial systems, procedures and controls, open new offices, and hire additional colleagues. Implementation of these new or upgraded systems, procedures,and controls may require substantial management efforts and our efforts to do so may not be successful. The opening of new offices (including internationallocations) or the hiring of additional colleagues may result in idle or underutilized capacity. We continually assess the expected capacity and utilization ofour offices and colleagues. We may not be able to achieve or maintain optimal utilization of our offices and colleagues. If demand for our services does notmeet our expectations, our revenues and cash flows may not be sufficient to offset these expenses and our results of operations and cash flows could beadversely affected.If we are unable to collect our receivables or unbilled services, our results of operations, financial condition, and cash flows could be adversely affected.Our business depends on our ability to successfully obtain payment from our clients of the amounts they owe us for work performed. We evaluate thefinancial condition of our clients and usually bill and collect on relatively short cycles. We have established allowances for losses of receivables andunbilled services. Actual losses on client balances could differ from those that we currently anticipate and as a result we might need to adjust our allowances.We might not accurately assess the credit worthiness of our clients. Macroeconomic conditions could also result in financial difficulties for our clients,including bankruptcy and insolvency. This could cause clients to delay payments to us, request modifications to their payment arrangements that couldincrease our receivables balance, or default on their payment obligations to us. Recovery of client financing and timely collection of client balances alsodepends upon our ability to complete our contractual commitments and bill and collect our contracted revenues. If we are unable to meet our contractualrequirements, we might experience delays in collection of and/or be unable to collect our client balances, and if this occurs, our results of operations and cashflows could be adversely affected. In addition, if we experience an increase in the time to bill and collect for our services, our cash flows could be adverselyaffected. 11 Our stock price and results of operations could fluctuate and be difficult to predict.Our stock price has fluctuated in the past and could continue to fluctuate in the future in response to various factors. These factors include:•changes in macroeconomic or political factors unrelated to our business;•the effect of the recently enacted 2017 Tax Act;•general or industry-specific market conditions or changes in financial markets;•announcements by us or competitors about developments in our business or prospects;•projections or speculation about our business or that of competitors by the media or investment analysts; and•our ability to meet our growth and financial objectives, including with respect to our overall revenue growth, revenue growth for our priorityemerging markets and earnings per share growth.Our results of operations have varied in the past and could vary significantly from quarter to quarter in the future, making them difficult to predict.Some of the factors that could cause our results of operations to vary include:•the business decisions of our clients to begin to curtail or reduce the use of our services, including in response to changes in macroeconomic orpolitical conditions unrelated to our business or general market conditions;•periodic differences between our clients’ estimated and actual levels of business activity associated with ongoing work, as well as the stage ofcompletion of existing projects and/or their termination or restructuring;•contract delivery inefficiencies, such as those due to poor delivery or changes in forecasts;•our ability to transition employees quickly from completed to new projects and maintain an appropriate headcount in each of our workforces;•acquisition, integration and operational costs related to businesses acquired;•the introduction of new products or services by us, competitors or partners;•changes in our pricing or competitors’ pricing;•our ability to manage costs, including those for our own or subcontracted personnel, travel, support services and severance;•our ability to limit and manage the incurrence of pre-contract costs, which must be expensed without corresponding revenues, which are thenrecognized in later periods without the corresponding costs;•changes in, or the application of changes in, accounting principles or pronouncements under U.S. generally accepted accounting principles,particularly those related to revenue recognition;•currency exchange rate fluctuations;•changes in estimates, accruals or payments of variable compensation to our employees;•global, regional and local economic and political conditions and related risks, including acts of terrorism; and•seasonality, including number of work days and holidays and summer vacations.12 As a result of any of the above factors, or any of the other risks described in this Item 1A, “Risk Factors,” our stock price could be difficult to predict,and our stock price in the past might not be a good indicator of the price of our stock in the future. We may need additional capital in the future, which may not be available to us. The raising of any additional capital may dilute your ownershippercentage in our stock.As of December 31, 2017, we had unrestricted cash and cash equivalents totaling $6.3 million and a borrowing capacity of $125.0 million, with$69.7 million unused capacity available, and a commitment from our lenders to increase our borrowing capacity by $75.0 million. Of the $6.3 million of cashand cash equivalents at December 31, 2017, $3.9 million was held by our Canadian, Indian and United Kingdom subsidiaries and is considered to beindefinitely reinvested in those operations. As of December 31, 2017, $1.8 million in cash and cash equivalents was held by our Chinese subsidiary and isnot considered indefinitely reinvested. We intend to continue to make investments to support our business growth and may require additional funds if ourcapital is insufficient to pursue business opportunities and respond to business challenges. Accordingly, we may need to engage in equity or debt financingsto secure additional funds. If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders couldsuffer dilution, and any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our common stock. Anydebt financing secured by us in the future could involve restrictive covenants relating to our capital raising activities and other financial and operationalmatters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. Inaddition, we may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing onterms satisfactory to us our ability to continue to support our business growth and to respond to business challenges could be significantly limited.Our officers, directors, and 5% and greater stockholders own a large percentage of our voting securities and their interests may differ from otherstockholders.Our executive officers, directors, and 5% and greater stockholders beneficially own or control approximately 34% of the voting power of ourcommon stock. This concentration of voting power of our common stock may make it difficult for our other stockholders to successfully approve or defeatmatters that may be submitted for action by our stockholders. It may also have the effect of delaying, deterring, or preventing a change in control of theCompany.It may be difficult for another company to acquire us, and this could depress our stock price.In addition to the voting securities held by our officers, directors, and 5% and greater stockholders, provisions contained in our certificate ofincorporation, bylaws, and Delaware law could make it difficult for a third party to acquire us, even if doing so would be beneficial to our stockholders. Ourcertificate of incorporation and bylaws may discourage, delay, or prevent a merger or acquisition that a stockholder may consider favorable by authorizingthe issuance of “blank check” preferred stock. In addition, provisions of the Delaware General Corporation Law also restrict some business combinations withinterested stockholders. These provisions are intended to encourage potential acquirers to negotiate with us and allow the Board of Directors the opportunityto consider alternative proposals in the interest of maximizing stockholder value. However, these provisions may also discourage acquisition proposals, ordelay or prevent a change in control, which could harm our stock price.Item 1B.Unresolved Staff Comments.None.Item 2.Properties.We have offices in multiple markets throughout the United States and in China, India, Canada, and the United Kingdom. We do not own any realproperty; all of our office space is leased with varying expiration dates. We believe our facilities are adequate to meet our needs in the near future.Item 3.Legal Proceedings.We are involved from time to time in various legal proceedings arising in the ordinary course of business. Although the outcome of lawsuits or otherproceedings cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot bepredicted accurately, we do not expect any currently pending matters to have a material adverse effect on the financial position, results of operations, or cashflows of the Company.Item 4.Mine Safety Disclosures.Not applicable.13 PART IIItem 5.Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.Our common stock is quoted on The Nasdaq Global Select Market under the symbol “PRFT.” The following table sets forth, for the periodsindicated, the high and low sale prices per share of our common stock as reported on The Nasdaq Global Select Market since January 1, 2016.

Any future determination as to the declaration and payment of dividends will bemade at the discretion of our board of directors and will depend on our earnings, operating and financial condition, capital requirements and other factorsdeemed relevant by our board of directors, including the applicable requirements of the Delaware General Corporation Law.Information on our Equity Compensation Plan has been included in Part III, Item 12 of this Annual Report on Form 10-K.Unregistered Sales of SecuritiesNone.Issuer Purchases of Equity SecuritiesPrior to 2018, our Board of Directors authorized the repurchase of up to $135.0 million of our common stock. On February 20, 2018, our Board ofDirectors authorized the expansion of our stock repurchase program by authorizing the repurchase of up to an additional $25.0 million of our common stockfor a total repurchase program of $160.0 million and extended the expiration date of the program to December 31, 2019. The program could be suspended ordiscontinued at any time, based on market, economic, or business conditions. The timing and amount of repurchase transactions will be determined by ourmanagement based on its evaluation of market conditions, share price, and other factors.Since the program’s inception on August 11, 2008, we have repurchased approximately $135.0 million (12.4 million shares) of our outstandingcommon stock through December 31, 2017.Period Total Numberof SharesPurchased Average PricePaid Per Share(1) Total NumberofSharesPurchased asPartof PubliclyAnnouncedPlans orPrograms ApproximateDollar Valueof Shares thatMay Yet BePurchasedUnder thePlans orPrograms Beginning Balance as of October 1, 2017 11,926,538 $10.59 11,926,538 $8,666,467 October 1-31, 2017 16,500 19.39 16,500 $8,346,459 November 1-30, 2017 260,536 18.69 260,536 $3,478,299 December 1-31, 2017 178,995 19.33 178,995 $17,691 Ending Balance as of December 31, 2017 12,382,569 $10.90 12,382,569 (1)Average price paid per share includes commission.14 Item 6.Selected Financial Data.The selected financial data presented for, and as of the end of, each of the years in the five-year period ended December 31, 2017, has been preparedin accordance with U.S. generally accepted accounting principles.

This Annual Report on Form 10-K may contain certain “forward-looking” information within the meaning of the Private Securities Litigation ReformAct of 1995. This information involves risks and uncertainties. Our actual results may differ materially from the results discussed in the forward-lookingstatements. Factors that might cause such a difference include, but are not limited to, those discussed in “Risk Factors.”OverviewWe are an information technology and management consulting firm serving Forbes Global 2000® and other large enterprise companies with aprimary focus on the United States. We help clients gain competitive advantage by using technology to: make their businesses more responsive to marketopportunities; strengthen relationships with customers, suppliers, and partners; improve productivity; and reduce information technology costs. Our digitalexperience, business optimization and industry solutions enable these benefits by developing, integrating, automating, and extending business processes,technology infrastructure and software applications end-to-end within an organization and with key partners, suppliers, and customers. Our solutions includeanalytics, custom applications, management consulting, commerce, content management, business integration, customer relationship management, portalsand collaboration, platform implementations, and business process management, among others. Our solutions enable our clients to operate a real-timeenterprise that dynamically adapts business processes and the systems that support them to meet the changing demands of an increasingly global, Internet-driven, and competitive marketplace.15 Services RevenuesServices revenues are derived from professional services that include developing, implementing, integrating, automating and extending businessprocesses, technology infrastructure, and software applications. Most of our projects are performed on a time and materials basis, while a portion of ourrevenues is derived from projects performed on a fixed fee basis. Fixed fee engagements represented approximately 8% of our services revenues for the yearended December 31, 2017 compared to 11% for each of the years ended December 31, 2016 and 2015. The decrease in fixed fee revenues is primarilyattributable to an organic decrease in fixed fee engagements overall. For time and material projects, revenues are recognized and billed by multiplying thenumber of hours our professionals expend in the performance of the project by the established billing rates. For fixed fee projects, revenues are generallyrecognized using an input method based on the ratio of hours expended to total estimated hours. Amounts invoiced and collected in excess of revenuesrecognized are classified as deferred revenues. In conjunction with services provided, we occasionally receive referral fees under partner programs. Thesereferral fees are recognized when earned and recorded within services revenues. On most projects, we are also reimbursed for out-of-pocket expensesincluding travel and other project-related expenses. These reimbursements are included as a component of revenues. The aggregate amount of reimbursedexpenses will fluctuate depending on the location of our clients, the total number of our projects that require travel, and whether our arrangements with ourclients provide for the reimbursement of such expenses.Software and Hardware RevenuesSoftware and hardware revenues are derived from sales of third-party and internally developed software and hardware. Revenues from sales of third-party software and hardware are generally recorded on a gross basis provided that we act as a principal in the transaction. Revenues from sales of third-partysoftware-as-a-service arrangements where we are not the primary obligor are recorded on a net basis. Software and hardware revenues are expected to fluctuatedepending on our clients’ demand for these products.If we enter into contracts for the sale of services and software or hardware, management evaluates whether each element should be accounted forseparately by considering the following criteria: (1) whether the deliverables have value to the client on a stand-alone basis; and (2) whether delivery orperformance of the undelivered item or items is considered probable and substantially in our control (only if the arrangement includes a general right ofreturn related to the delivered item). Further, for sales of software and services, management also evaluates whether the services are essential to thefunctionality of the software and whether there is fair value evidence for each deliverable. If management concludes that the separation criteria are met, thenit accounts for each deliverable in the transaction separately, based on the relevant revenue recognition policies. Generally, all deliverables of our multipleelement arrangements meet these criteria and are accounted for separately, with the arrangement consideration allocated among the deliverables using vendorspecific objective evidence of the selling price. As a result, we generally recognize software and hardware sales upon delivery to the customer and servicesconsistent with the policies described herein.Further, delivery of software and hardware sales, when sold contemporaneously with services, can generally occur at varying times depending on thespecific client project arrangement. Delivery of services generally occurs over a period of time consistent with the timeline as outlined in the client contract. There are no significant cancellation or termination-type provisions for our software and hardware sales. Contracts for our professional servicesprovide for a general right, to the client or us, to cancel or terminate the contract within a given period of time (generally 10 to 30 days’ notice is required).The client is responsible for any time and expenses incurred up to the date of cancellation or termination of the contract.Cost of RevenuesCost of revenues consists of cost of services, software and hardware costs, and reimbursable expenses. Cost of services consists primarily of cash andnon-cash compensation and benefits (including bonuses and non-cash compensation related to equity awards), costs associated with subcontractors and otherunreimbursed project-related expenses. Cost of revenues does not include depreciation of assets used in the production of revenues which are primarilypersonal computers, servers, and other information technology related equipment.Our cost of services as a percentage of services revenues is affected by the utilization rates of our professionals (defined as the percentage of ourprofessionals’ time billed to clients divided by the total available hours in the respective period), the salaries we pay our professionals, and the averagebilling rate we receive from our clients. If a project ends earlier than scheduled, we retain professionals in advance of receiving project assignments, ordemand for our services declines, our utilization rate will decline and adversely affect our cost of services as a percentage of services revenues. Software andhardware costs as a percentage of software and hardware revenues (excluding internally developed software) are typically higher than cost of services as apercentage of services revenues, and the mix of services and software and hardware for a particular period can significantly impact our total combined cost ofrevenues as a percentage of total revenues for such period. In addition, software and hardware costs as a percentage of software and hardware revenues canfluctuate due to pricing and other competitive pressures. Selling, General, and Administrative ExpensesSelling, general and administrative (“SG&A”) expenses are primarily composed of sales-related costs, general and administrative salaries, stockcompensation expense, office costs, recruiting expense, variable compensation costs, marketing costs and other miscellaneous expenses. We have access tosales leads generated by our software vendors, most notably IBM, Oracle and Microsoft, whose products we use to design and implement solutions for ourclients. These relationships enable us to optimize our selling costs and sales cycle times and increase win rates through leveraging our partners’ marketingefforts and endorsements.Plans for Growth and AcquisitionsOur goal is to continue to build one of the leading information technology consulting firms by expanding our relationships with existing and newclients and through the continuation of our disciplined acquisition strategy. Our future growth plan includes expanding our business with a primary focus oncustomers in the United States, both organically and through acquisitions. We also intend to further leverage our existing offshore capabilities to support ourfuture growth and provide our clients flexible options for project delivery.When analyzing revenue growth by base business compared to acquired companies in the Results of Operations section below, revenue attributableto base business includes revenue from an acquired company that has been owned for a full four quarters after the date of acquisition.16 United States Tax ReformThe 2017 Tax Act was signed into law on December 22, 2017. The law includes significant changes to the U.S. corporate income tax system,including a federal corporate tax rate reduction from 35% to 21%, limitations on the deductibility of interest expense and executive compensation, and thetransition of U.S. international taxation from a worldwide tax system to a territorial tax system. This change may result in a U.S. tax liability on those earningswhich have not previously been repatriated to the U.S., with future foreign earnings potentially not subject to U.S. income taxes when repatriated. See Note10, Income Taxes, in the Notes to Consolidated Financial Statements for a discussion of the Company’s repatriation of earnings from the Company’s Chinesesubsidiary. The majority of the provisions will have an impact on Perficient beginning in fiscal years 2018 and 2019. However, there are certain transitionalimpacts of the 2017 Tax Act which affected the Company’s tax provision during the fourth quarter of 2017. As part of the transition to the new territorial taxsystem, the 2017 Tax Act imposed a one-time repatriation tax on deemed repatriation of historical earnings of foreign subsidiaries, which produced a $1.1million tax expense payable over eight years. As a result, a $0.1 million current liability and a $1.0 million non-current liability were recorded in theCompany’s consolidated financial statements during the fourth quarter of 2017. The reduction of the federal corporate tax rate caused the Company to adjustits U.S. deferred tax assets and liabilities to the lower federal base rate of 21%. The reduction in the corporate tax rate resulted in a provisional net tax creditof $3.3 million for the fourth quarter of 2017. In addition, as a result of the 2017 Tax Act, changes to the net tax cost of certain China dividends repatriatedduring 2017 created a $1.6 million tax credit during the fourth quarter of 2017. There were no specific impacts of the 2017 Tax Act that could not be reasonably estimated which the Company accounted for under prior tax law. However, the SEC has issued rules that would allow for a measurement period of up to one year after the enactment date of the 2017 Tax Act to finalize therecording of the related tax impacts. Based on a continued analysis of the estimates and further guidance on the application of the law, it is anticipated thatadditional revisions may occur throughout the allowable measurement period. We currently anticipate finalizing and recording any resulting adjustmentswithin a year of the enactment date. See Note 10, Income Taxes, in the Notes to the Consolidated Financial Statements for additional information regardingthe 2017 Tax Act.Revenue Recognition Standard Adopted January 1, 2018In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue fromContracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods orservices to customers. ASU No. 2014-09 replaced most existing revenue recognition guidance in U.S. GAAP. In 2015, the FASB deferred the effective date ofASU No. 2014-09 by one year. In 2016, the FASB issued ASU No. 2016-08, Principal versus Agent Considerations, ASU No. 2016-10, IdentifyingPerformance Obligations and Licensing, ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients and ASU No. 2016-20, TechnicalCorrections and Improvements to Topic 606, Revenue from Contracts with Customers, all of which further amended ASU No. 2014-09. The Companyadopted the standard on January 1, 2018 using the modified retrospective method, which requires a cumulative-effect adjustment to the opening balance ofretained earnings within stockholders’ equity, as will be fully presented in the Company’s Quarterly Report on Form 10-Q for the three months ended March31, 2018. The Company has determined that the most significant impact upon adoption is to third-party software and hardware revenue, which has primarilybeen recorded on a gross basis as the principal in the transaction through December 31, 2017 and will be presented on a net basis as the agent as of January 1,2018. Had the Company historically presented third-party software and hardware revenues on a net basis, software and hardware revenues would have been$5.3 million, $6.4 million, and $5.5 million for the years ended December 31, 2017, 2016, and 2015, respectively. As the Company adopted ASU No. 2014-09 using the modified retrospective method, the gross versus net presentation will not impact the historical presentation, but will impact the 2018presentation. Additionally, as the agent, revenue from multi-year sales of third-party software and support will be recognized upfront as the performanceobligation is fulfilled, rather than annually as invoiced to the customer. The impact from this timing change is expected to be immaterial. Variableconsideration related to service contracts, such as volume discounts and holdbacks, may be recognized earlier under the new standard, and the Company iscurrently evaluating the impact of this change on contracts that are open as of December 31, 2017. The adoption of ASU No. 2014-09 and its amendmentswill also result in additional disclosures around the nature and timing of performance obligations, contract costs, and deferred revenue, as well as significantjudgments and practical expedients used by the Company.Results of OperationsThe following table summarizes our results of operations as a percentage of total revenues:Revenues: 2017 2016 2015 Services revenues 89.5% 85.9% 86.9%Software and hardware revenues 8.0 10.3 9.8 Reimbursable expenses 2.5 3.8 3.3 Total revenues 100.0 100.0 100.0 Cost of revenues (depreciation and amortization, shown separately below): Cost of services 57.3 56.2 55.2 Software and hardware costs 6.9 8.9 8.7 Reimbursable expenses 2.5 3.8 3.3 Total cost of revenues 66.7 68.9 67.2 Selling, general and administrative 22.3 20.8 21.1 Depreciation and amortization 4.1 3.7 3.9 Acquisition costs 0.3 0.3 0.3 Adjustment to fair value of contingent consideration 0.7 (0.3) 0.1 Income from operations 6.0 6.6 7.4 Net interest expense 0.4 0.3 0.4 Net other expense 0.0 0.0 0.1 Income before income taxes 5.6 6.3 6.9 Provision for income taxes 1.8 2.1 2.0 Net income 3.8% 4.2% 4.9%17 Year Ended December 31, 2017 Compared to Year Ended December 31, 2016Revenues.

Services revenues attributable to our base business decreased $17.9 million whileservices revenues attributable to acquired companies was $33.6 million, resulting in a total increase of $15.7 million.Software and hardware revenues decreased 23% to $38.6 million for the year ended December 31, 2017 from $50.0 million for the year endedDecember 31, 2016 primarily due to a decrease in initial and renewal software license sales. Reimbursable expenses decreased 33% to $12.4 million for theyear ended December 31, 2017 from $18.4 million for the year ended December 31, 2016 primarily as a result of a higher mix of projects performed in ouroffices and lower media buy expenses passed through to customers of $2.6 million. We do not realize any profit on reimbursable expenses.Cost of Revenues (exclusive of depreciation and amortization, discussed separately below). Cost of revenues decreased 4% to $323.7 million for theyear ended December 31, 2017 from $335.7 million for the year ended December 31, 2016. The decrease in cost of revenues is primarily related to softwareand hardware costs which decreased 24% to $33.3 million for the year ended December 31, 2017 from $43.6 million for the year ended December 31, 2016,as a result of the decrease in software license sales. Software and hardware costs as a percentage of software and hardware revenues was 86.2% for the yearended December 31, 2017 and 87.2% for the year ended December 31, 2016. Services revenue costs increased 2% to $278.1 million for the year endedDecember 31, 2017 from $273.7 million for the year ended December 31, 2016 due to an increase in service revenue as noted above. Services costs as apercentage of services revenues decreased to 64.0% for the year ended December 31, 2017 from 65.4% for the year ended December 31, 2016 primarilydriven by improvements in the North American average bill rate and utilization, as well as a $1.0 million cost reduction related to labor incentives earned bythe Company’s Louisiana and China operations. The average bill rate for our professionals decreased to $126 per hour for the year ended December 31, 2017from $127 per hour for the year ended December 31, 2016 primarily due to the impact of a higher mix of lower bill rate offshore resources.18 Selling, General and Administrative. SG&A expenses increased 7% to $108.2 million for the year ended December 31, 2017 from $101.3 million forthe year ended December 31, 2016 primarily due to acquisitions completed during the first half of 2017 and the fluctuations in expenses as detailed in thefollowing table. SG&A expenses, as a percentage of total revenues, increased to 22.3% for the year ended December 31, 2017 from 20.8% for the year endedDecember 31, 2016.Selling, General and Administrative Expense (in millions) For the YearEndedDecember 31,2017 For the YearEndedDecember 31,2016 Increase(Decrease) PercentageChange Sales-related costs $30.3 $28.4 $1.9 7%Salary expense 26.3 25.3 1.0 4 Stock compensation expense 9.3 8.9 0.4 4 Office costs 9.2 8.9 0.3 3 Marketing expense 5.9 5.6 0.3 5 Variable compensation expense 5.2 2.0 3.2 160 Recruiting expense 5.1 5.7 (0.6) (11)Bad debt expense 0.9 1.1 (0.2) (18)Other 16.0 15.4 0.6 4 Total $108.2 $101.3 $6.9 7%Depreciation. Depreciation expense decreased 3% to $4.7 million for the year ended December 31, 2017 from $4.9 million for the year endedDecember 31, 2016. The decrease in depreciation expense is primarily attributable to certain property and equipment becoming fullydepreciated. Depreciation expense as a percentage of total revenues was 1.0% for each of the years ended December 31, 2017 and 2016.Amortization. Amortization expense increased 12% to $15.0 million for the year ended December 31, 2017 from $13.4 million for the year endedDecember 31, 2016. The increase in amortization expense was due to the addition of intangible assets from the 2016 and 2017 acquisitions, partially offsetby intangible assets from previous acquisitions becoming fully amortized. Amortization expense as a percentage of total revenues was 3.1% for the yearended December 31, 2017 and 2.7% for the year ended December 31, 2016.Acquisition Costs. Acquisition-related costs of $1.4 million were incurred during 2017 compared to $1.3 million during 2016. Costs were incurredfor legal, accounting, tax, investment bank and advisor fees, and valuation services performed by third parties in connection with merger and acquisition-related activities.Adjustment to Fair Value of Contingent Consideration. An unfavorable adjustment of $3.2 million was recorded during the year ended December31, 2017 which represents the net impact of the fair market value adjustments to the Clarity, RAS, and Bluetube revenue and earnings-based contingentconsideration liabilities in addition to the accretion of the fair value estimate for the revenue and earnings-based contingent consideration related to theacquisition of Bluetube and Clarity. A favorable adjustment of $1.7 million was recorded during the year ended December 31, 2016 which represents the netimpact of the fair market value adjustments to the Enlighten revenue and earnings-based contingent consideration liability partially offset by the accretion ofthe fair value estimate for the revenue and earnings-based contingent consideration related to the acquisition of Zeon, Market Street, Enlighten and Bluetube.Provision for Income Taxes. We provide for federal, state, and foreign income taxes at the applicable statutory rates adjusted for non-deductibleexpenses. The effective income tax rate decreased to 31.5% for the year ended December 31, 2017 from 32.9% for the year ended December 31, 2016. Thedecrease in the effective rate is primarily due to the effects of certain foreign withholding taxes, a foreign toll charge on historic foreign earnings, and arevaluation of ending deferred income tax caused by passage of the 2017 Tax Act. These favorable items were partially offset by an increase in ourunrecognized tax benefits. See Note 10, Income Taxes, in the Notes to the Consolidated Financial Statements for additional information regarding the 2017Tax Act.19 Year Ended December 31, 2016 Compared to Year Ended December 31, 2015Revenues. Total revenues increased 3% to $487.0 million for the year ended December 31, 2016 from $473.6 million for the year ended December31, 2015.

Services revenues attributable to our base business decreased $9.3 million while servicesrevenues attributable to acquired companies was $16.4 million, resulting in a total increase of $7.1 million.Software and hardware revenues increased 7% to $50.0 million for the year ended December 31, 2016 from $46.6 million for the year endedDecember 31, 2015 primarily due to acquisitions. Reimbursable expenses increased 19% to $18.4 million for the year ended December 31, 2016 from $15.5million for the year ended December 31, 2015. The increase in reimbursable expenses is primarily due to the acquisition of Enlighten in which media buyexpenses are passed through to customers. We do not realize any profit on reimbursable expenses.Cost of Revenues (exclusive of depreciation and amortization, discussed separately below). Cost of revenues increased 5% to $335.7 million for theyear ended December 31, 2016 from $318.4 million for the year ended December 31, 2015. The increase in cost of revenues is primarily related to costsassociated with services revenues which increased 5% to $273.7 million for the year ended December 31, 2016 from $261.7 million for the year endedDecember 31, 2015 due to an increase in revenue as noted above. Services costs as a percentage of services revenues increased to 65.4% for the year endedDecember 31, 2016 from 63.6% for the year ended December 31, 2015 primarily driven by a decrease in the average bill rate of our professionals, in additionto higher salaries and subcontractor costs. The average bill rate decreased to $127 per hour for the year ended December 31, 2016 from $134 per hour for theyear ended December 31, 2015 primarily due to the impact of a higher mix of lower bill rate offshore resources combined with a 1% reduction in the NorthAmerican employee bill rate. Software and hardware costs increased 6% to $43.6 million for the year ended December 31, 2016 from $41.2 million for theyear ended December 31, 2015, as a result of the increase in software license sales. Software and hardware costs as a percentage of software and hardwarerevenues was 87.2% for the year ended December 31, 2016 and 88.3% for the year ended December 31, 2015.Selling, General and Administrative. SG&A expenses increased 1% to $101.3 million for the year ended December 31, 2016 from $100.0 million forthe year ended December 31, 2015 primarily due to acquisitions completed during the second half of 2015 and October 2016 and the fluctuations inexpenses as detailed in the following table. SG&A expenses, as a percentage of total revenues, decreased to 20.8% for the year ended December 31, 2016from 21.1% for the year ended December 31, 2015.Selling, General and Administrative Expense (in millions) For the YearEndedDecember 31,2016 For the YearEndedDecember 31,2015 Increase(Decrease) PercentageChange Sales-related costs $28.4 $29.1 $(0.7) (2)%Salary expense 25.3 23.9 1.4 6 Stock compensation expense 8.9 8.7 0.2 2 Office costs 8.9 8.2 0.7 9 Recruiting expense 5.7 6.0 (0.3) (5)Marketing expense 5.6 5.6 0.0 0 Variable compensation expense 2.0 3.4 (1.4) (41)Bad debt expense 1.1 0.4 0.7 175 Other 15.4 14.7 0.7 5 Total $101.3 $100.0 $1.3 1%20 Depreciation. Depreciation expense increased 8% to $4.9 million for the year ended December 31, 2016 from $4.5 million for the year endedDecember 31, 2015. The increase in depreciation expense is primarily attributable to an increase in capital expenditures to support our growth. Depreciationexpense as a percentage of total revenues was 1.0% and 0.9% for the years ended December 31, 2016 and 2015, respectively.Amortization. Amortization expense decreased 3% to $13.4 million for the year ended December 31, 2016 from $13.8 million for the year endedDecember 31, 2015. The decrease in amortization expense was due to intangible assets related to previous acquisitions becoming fully amortized partiallyoffset by the addition of intangible assets from the 2015 and 2016 acquisitions. Amortization expense as a percentage of total revenues was 2.7% for the yearended December 31, 2016 and 2.9% for the year ended December 31, 2015.Acquisition Costs. Acquisition-related costs of $1.3 million were incurred during 2016 compared to $1.2 million during 2015. Costs were incurredfor legal, accounting, tax, investment bank and advisor fees, and valuation services performed by third parties in connection with merger and acquisition-related activities.Adjustment to Fair Value of Contingent Consideration. A favorable adjustment of $1.7 million was recorded during the year ended December 31,2016 which represents the net impact of the fair market value adjustments to the Enlighten revenue and earnings-based contingent consideration liabilitypartially offset by the accretion of the fair value estimate for the revenue and earnings-based contingent consideration related to the acquisition of Zeon,Market Street, Enlighten and Bluetube. An adjustment of $0.4 million was recorded during the year ended December 31, 2015 for the accretion of the fairvalue estimate for the revenue and earnings-based contingent consideration related to the acquisitions of the Zeon, Market Street, and Enlighten.Provision for Income Taxes. We provide for federal, state, and foreign income taxes at the applicable statutory rates adjusted for non-deductibleexpenses. The effective income tax rate increased to 32.9% for the year ended December 31, 2016 from 29.9% for the year ended December 31, 2015. Theincrease in the effective rate is primarily due to an additional research and development tax credit recorded during the year ended December 31, 2015 relatedto the finalization of the Company’s 2014 research and development tax assessment. The increase in the effective rate year ended December 31, 2016 waspartially offset by an incremental research and development tax credit related to the current year and a favorable impact related to the early adoption of ASUNo. 2016-09. See Note 2, Summary of Significant Accounting Policies-Recent Accounting Pronouncements, in the Notes to Consolidated FinancialStatements for additional information regarding the adoption of ASU No. 2016-09.Liquidity and Capital ResourcesSelected measures of liquidity and capital resources are as follows (in millions): As of December 31, 2017 2016 2015 Cash and cash equivalents (1) $6.3 $10.1 $8.8 Working capital (including cash and cash equivalents) (2) $67.9 $76.4 $83.2 Amounts available under credit facilities $69.7 $93.0 $69.0 (1) The balance at December 31, 2017 includes $3.9 million held by our Canadian, Indian and United Kingdom subsidiaries which is not available to funddomestic operations unless deemed repatriated. We currently do not plan or foresee a need to repatriate such funds. The balance also includes $1.8 millionin cash held in our Chinese subsidiary. During the year ended December 31, 2017, the Company determined that the Chinese subsidiary’s earnings were nolonger permanently reinvested and repatriated a total of approximately $9.6 million in cash to the U.S. parent in the second and third quarters of 2017. SeeNote 10, Income Taxes, in the Notes to Consolidated Financial Statements for a discussion of the Company’s repatriation of earnings from the Company’sChinese subsidiary.(2) Working capital is total current assets less total current liabilitiesNet Cash Provided By Operating ActivitiesNet cash provided by operating activities for the year ended December 31, 2017 was $55.2 million compared to $63.3 million and $44.7 million forthe years ended December 31, 2016 and 2015, respectively. For the year ended December 31, 2017, the components of operating cash flows were net incomeof $18.6 million plus net non-cash charges of $33.2 million and reductions in net operating assets of $3.5 million. The primary components of operating cashflows for the year ended December 31, 2016 were net income of $20.5 million plus net non-cash charges of $34.9 million and reductions in net operatingassets of $7.9 million, primarily driven by reductions in accounts receivable. The primary components of operating cash flows for the year ended December31, 2015 were net income of $23.0 million plus net non-cash charges of $31.9 million and investments in net operating assets of $10.2 million.Net Cash Used in Investing ActivitiesDuring the year ended December 31, 2017, we used $37.9 million for acquisitions and $4.3 million to purchase property and equipment and todevelop software. During the year ended December 31, 2016, we used $7.5 million for acquisitions and $6.1 million to purchase property and equipment andto develop software. During the year ended December 31, 2016, we also purchased and subsequently sold short-term investments of $0.9 million and settled$2.8 million of Company-owned life insurance (“COLI”) policies, the proceeds of which were used to fund new COLI policies. For the year ended December31, 2015, we used $37.8 million for acquisitions (net of cash acquired) and $4.4 million to purchase property and equipment and to develop software.Net Cash Provided By Financing ActivitiesFor the year ended December 31, 2017, we received proceeds of $275.0 million from our line of credit and $0.1 million in proceeds from the sales ofstock through the Employee Stock Purchase Plan. In 2017, we made payments of $252.0 million on our line of credit, used $32.6 million to repurchase sharesof our common stock through the stock repurchase program and used $4.2 million to remit taxes withheld as part of a net share settlement of restricted stockvesting. We also used $3.3 million to settle the contingent consideration for the purchase of Market Street, Enlighten and Bluetube and paid $0.4 million infees related to our credit facility. For the year ended December 31, 2016, we received proceeds of $208.5 million from our line of credit and $0.2 million inproceeds from the sales of stock through the Employee Stock Purchase Plan. In 2016, we made payments of $232.5 million on our line of credit, used $18.0million to repurchase shares of our common stock through the stock repurchase program and used $3.7 million to remit taxes withheld as part of a net sharesettlement of restricted stock vesting. We also used $2.1 million to settle the contingent consideration for the purchase of Zeon and paid $0.2 million in feesrelated to our credit facility. For the year ended December 31, 2015, we received proceeds of $266.5 million from our line of credit and we realized a taxbenefit of $1.4 million related to the vesting of stock awards and stock option exercises plus $0.3 million in proceeds from the exercise of stock options and sales of stock through the Employee Stock Purchase Plan. In 2015, we made payments of $264.5 million on our line of credit, used $5.0 million to remit taxeswithheld as part of a net share settlement of restricted stock vesting, used $2.8 million to repurchase shares of our common stock through the stock repurchaseprogram and paid $0.2 million in fees related to our credit facility.21 Availability of Funds from Credit FacilityOn June 9, 2017, we entered into a Credit Agreement, as amended (the “Credit Agreement”), with Wells Fargo Bank, National Association, asadministrative agent and the other lenders parties thereto. The Credit Agreement replaces the Second Amended and Restated Credit Agreement dated as ofJuly 31, 2013 between the Company, Silicon Valley Bank and the other lenders and signatories thereto (the “Prior Credit Agreement”). The new creditfacility was used to repay amounts due under the Prior Credit Agreement and will be used for working capital and general corporate purposes. In connectionwith the new agreement, the Company wrote off $0.2 million in unamortized credit facility fees associated with the Prior Credit Agreement, which wasincluded in “Net interest expense” on the Consolidated Statements of Operations during the year ended December 31, 2017. The Credit Agreement providesfor revolving credit borrowings up to a maximum principal amount of $125.0 million, subject to a commitment increase of $75.0 million. All outstandingamounts owed under the Credit Agreement become due and payable no later than the final maturity date of June 9, 2022.The Credit Agreement also allows for the issuance of letters of credit in the aggregate amount of up to $10.0 million at any one time; outstandingletters of credit reduce the credit available for revolving credit borrowings. As of December 31, 2017, the Company had one outstanding letter of credit for$0.3 million. Substantially all of the Company’s assets are pledged to secure the credit facility.Borrowings under the Credit Agreement bear interest at the Company’s option of the prime rate (4.50% on December 31, 2017) plus a marginranging from 0.00% to 0.50% or one-month LIBOR (1.56% on December 31, 2017) plus a margin ranging from 1.00% to 1.75%. The Company incurs anannual commitment fee of 0.15% to 0.20% on the unused portion of the line of credit. The additional margin amount and annual commitment fee aredependent on the level of outstanding borrowings. As of December 31, 2017, the Company had $69.7 million of unused borrowing capacity.At December 31, 2017, we were in compliance with all covenants under the Credit Agreement.Stock Repurchase ProgramPrior to 2018, our Board of Directors authorized the repurchase of up to $135.0 million of our common stock. On February 20, 2018, our Board ofDirectors authorized the expansion of our stock repurchase program by authorizing the repurchase of up to an additional $25.0 million of our common stockfor a total repurchase program of $160.0 million and extended the expiration date of the program to December 31, 2019. The program could be suspended ordiscontinued at any time, based on market, economic, or business conditions. The timing and amount of repurchase transactions will be determined by ourmanagement based on its evaluation of market conditions, share price, and other factors. From time to time, we establish a written trading plan in accordance with Rule 10b5-1 of the Exchange Act, pursuant to which we make a portion ofour stock repurchases. Additional repurchases will be at times and in amounts as the Company deems appropriate and will be made through open markettransactions in compliance with Rule 10b-18 of the Exchange Act, subject to market conditions, applicable legal requirements, and other factors. Since the program’s inception on August 11, 2008, we have repurchased approximately $135.0 million (12.4 million shares) of our outstandingcommon stock through December 31, 2017.Contractual ObligationsFor the year ended December 31, 2017, there were no material changes outside the ordinary course of business in lease obligations or othercontractual obligations. See Note 12, Commitments and Contingencies, in the Notes to Consolidated Financial Statements for further description of ourcontractual obligations.As of December 31, 2017, there was $55.0 million outstanding under the Credit Agreement as compared to $32.0 million outstanding under the PriorCredit Agreement as of December 31, 2016. The amounts under the Credit Agreement are classified as “Long-term debt” within the Consolidated BalanceSheets and will become due and payable no later than the final maturity date of June 9, 2022.We have incurred commitments to make future payments under contracts such as leases and the Credit Agreement. Maturities under these contractsare set forth in the following table as of December 31, 2017 (in thousands): Payments Due by Period Contractual Obligations Total Less Than1 Year 1-3Years 3-5Years More Than5 Years Operating lease obligations $29,484 $6,535 $12,611 $7,368 $2,970 Software license purchase obligation 835 835 - - - Total debt 55,000 - - 55,000 - Total $85,319 $7,370 $12,611 $62,368 $2,970 22 ConclusionIf our capital is insufficient to fund our activities in either the short- or long-term, we may need to raise additional funds. In the ordinary course ofbusiness, we may engage in discussions with various persons in connection with additional financing. If we raise additional funds through the issuance ofequity securities, our existing stockholders’ percentage ownership will be diluted. These equity securities may also have rights superior to our common stock.Additional debt or equity financing may not be available when needed or on satisfactory terms. If adequate funds are not available on acceptable terms, wemay be unable to expand our services, respond to competition, pursue acquisition opportunities, or continue our operations.Of the total cash and cash equivalents reported on the Consolidated Balance Sheet as of December 31, 2017 of $6.3 million, approximately $3.9million was held by the Company’s Canadian, Indian and United Kingdom subsidiaries and is considered to be indefinitely reinvested in those operations.The Company is able to fund its liquidity needs outside of these subsidiaries, primarily through cash flows generated by domestic operations and our creditfacility. Therefore, the Company has no current plans to repatriate cash from these foreign subsidiaries in the foreseeable future. As of December 31, 2017, theaggregate unremitted earnings of the Company’s foreign subsidiaries for which a deferred income tax liability has not been recorded was approximately $4.9million, and the unrecognized deferred tax liability on unremitted earnings was approximately $0.2 million. See Note 10, Income Taxes, in the Notes toConsolidated Financial Statements for a discussion of the Company’s repatriation of earnings from the Company’s Chinese subsidiary.We believe that the currently available funds, access to capital from our credit facility, and cash flows generated from operations will be sufficient tomeet our working capital requirements and other capital needs for the next 12 months.Critical Accounting PoliciesOur accounting policies are fully described in Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated FinancialStatements. We believe our most critical accounting policies include revenue recognition, purchase accounting and related fair value measurements andincome taxes.Revenue Recognition and Allowance for Doubtful AccountsService revenues are primarily derived from professional services provided on a time and materials basis. For time and material contracts, servicerevenues are recognized and billed by multiplying the number of hours expended in the performance of the contract by the established billing rates. For fixedfee projects, service revenues are generally recognized using an input method based on the ratio of hours expended to total estimated hours. Amountsinvoiced and collected in excess of revenues recognized are classified as deferred revenues. In conjunction with services provided, the Companyoccasionally receives referral fees under partner programs. These referral fees are recognized when earned and recorded within service revenues. Revenuesfrom software and hardware sales are generally recorded on a gross basis considering the Company’s role as a principal in the transaction. Revenues fromsales of third-party software-as-a-service arrangements where the Company is not the primary obligor are recorded on a net basis. On many projects theCompany is also reimbursed for out-of-pocket expenses including travel and other project-related expenses. These reimbursements are included as acomponent of revenues. We did not realize any profit on reimbursable expenses.Unbilled revenues represent the project time and expenses that have been incurred, but not yet billed to the client, prior to the end of the fiscalperiod. For time and materials projects, the client is invoiced for the amount of hours worked multiplied by the billing rates as stated in the contract. For fixedfee arrangements, the client is invoiced according to the agreed-upon schedule detailing the amount and timing of payments in the contract. Clients aretypically billed monthly for services provided during that month, but can be billed on a more or less frequent basis as determined by the contract. If the timeand expenses are worked/incurred and approved at the end of a fiscal period and the invoice has not yet been sent to the client, the amount is recorded asunbilled revenue once the Company verifies all other revenue recognition criteria have been met.Revenues are recognized when the following criteria are met: (1) persuasive evidence of the customer arrangement exists; (2) fees are fixed anddeterminable; (3) delivery and acceptance have occurred; and (4) collectability is deemed probable. The Company’s policy for revenue recognition ininstances where multiple deliverables are sold contemporaneously to the same customer is in accordance with the FASB Accounting Standards Codification(“ASC”) Subtopic 985-605, Software – Revenue Recognition, ASC Subtopic 605-25, Revenue Recognition – Multiple-Element Arrangements, and ASCSection 605-10-S99 (Staff Accounting Bulletin Topic 13, Revenue Recognition). Specifically, if the Company enters into contracts for the sale of servicesand software or hardware, then the Company evaluates whether each element should be accounted for separately by considering the following criteria: (1)whether the deliverables have value to the client on a stand-alone basis; and (2) whether delivery or performance of the undelivered item or items isconsidered probable and substantially in the control of the Company (only if the arrangement includes a general right of return related to the delivered item).Further, for sales of software and services, the Company also evaluates whether the services are essential to the functionality of the software and if it has fairvalue evidence for each deliverable. If the Company has concluded that the separation criteria are met, then it accounts for each deliverable in the transactionseparately, based on the relevant revenue recognition policies. Generally, all deliverables of the Company’s multiple element arrangements meet thesecriteria and are accounted for separately, with the arrangement consideration allocated among the deliverables using vendor specific objective evidence ofthe selling price. As a result, the Company generally recognizes software and hardware sales upon delivery to the customer and services consistent with thepolicies described herein.Further, delivery of software and hardware sales, when sold contemporaneously with services, can generally occur at varying times depending on thespecific client project arrangement. Delivery of services generally occurs over a period of time consistent with the timeline as outlined in the client contract.There are no significant cancellation or termination-type provisions for the Company’s software and hardware sales. Contracts for professionalservices provide for a general right, to the client or the Company, to cancel or terminate the contract within a given period of time (generally 10 to 30 days’notice is required). The client is responsible for any time and expenses incurred up to the date of cancellation or termination of the contract.The Company may provide multiple services under the terms of an arrangement and is required to assess whether one or more units of accounting arepresent. Service fees are typically accounted for as one unit of accounting, as fair value evidence for individual tasks or milestones is not available. TheCompany follows the guidelines discussed above in determining revenues; however, certain judgments and estimates are made and used to determinerevenues recognized in any accounting period. If estimates are revised, material differences may result in the amount and timing of revenues recognized for agiven period. Revenues are presented net of taxes assessed by governmental authorities. Sales taxes are generally collected and subsequently remitted on allsoftware and hardware sales and certain services transactions as appropriate.Allowance for doubtful accounts is based upon specific identification of likely and probable losses. Each accounting period, accounts receivable isevaluated for risk associated with a client’s inability to make contractual payments, historical experience and other currently available information. Billedand unbilled receivables that are specifically identified as being at risk are provided for with a charge to revenue or bad debts as appropriate in the period therisk is identified. Considerable judgment is used in assessing the ultimate realization of these receivables, including reviewing the financial stability of theclient, evaluating the successful mitigation of service delivery disputes, and gauging current market conditions. If the evaluation of service delivery issues ora client’s ability to pay is incorrect, future reductions to revenue or bad debt expense may be incurred.23 Purchase Accounting and Related Fair Value MeasurementsThe Company allocates the purchase price, including contingent consideration, of our acquisitions to the assets and liabilities acquired, includingidentifiable intangible assets, based on their respective fair values at the date of acquisition. Such fair market value assessments are primarily based on third-party valuations using assumptions developed by management that require significant judgments and estimates that can change materially as additionalinformation becomes available. The purchase price allocated to intangibles is based on unobservable factors, including but not limited to, projectedrevenues, expenses, customer attrition rates, royalty rates, a weighted average cost of capital, among others. The weighted average cost of capital uses amarket participant’s cost of equity and after-tax cost of debt and reflects the risk inherent in the cash flows. The approach to valuing the contingentconsideration associated with the purchase price also uses similar unobservable factors such as projected revenues and expenses over the term of thecontingent earn-out period, discounted for the period over which the contingent consideration is measured. Based upon these assumptions, the contingentconsideration is then valued using a Monte Carlo simulation. The Company finalizes the purchase price allocation within 12 months of the acquisition dateas certain initial accounting valuation estimates are finalized.Income TaxesThe Company calculates and provides for income taxes in each jurisdiction in which it operates. Deferred tax assets and liabilities, measured usingenacted tax rates, are recognized for the future tax consequences of temporary differences between financial reporting and tax bases of assets and liabilities. Avaluation allowance reduces the deferred tax assets to the amount that is more likely than not to be realized. The Company has established liabilities orreduced assets for uncertain tax positions when it believes those tax positions are not more likely than not of being sustained if challenged. The Companyevaluates these uncertain tax positions and adjusts the related tax assets and liabilities in light of changing facts and circumstances each quarter. OnDecember 22, 2017, the U.S. government enacted the 2017 Tax Act. The 2017 Tax Act significantly revised the future ongoing U.S. corporate income tax by,among other things, lowering U.S. corporate income tax rates and implementing a territorial tax system. See Note 10, Income Taxes, in the Notes to theConsolidated Financial Statements for additional information regarding the 2017 Tax Act.Recent Accounting PronouncementsRecent accounting pronouncements are fully described in Note 2, Summary of Significant Accounting Policies, in the Notes to ConsolidatedFinancial Statements.Off-Balance Sheet ArrangementsWe have no off-balance sheet arrangements, except operating lease commitments as disclosed in Note 12, Commitments and Contingencies, in theNotes to Consolidated Financial Statements.Item 7A.Quantitative and Qualitative Disclosures About Market Risk.We are exposed to market risks related to changes in foreign currency exchange rates and interest rates. We believe our exposure to market risks isimmaterial.Exchange Rate SensitivityWe are exposed to market risks associated with changes in foreign currency exchange rates because we generate a portion of our revenues and incura portion of our expenses in currencies other than the U.S. dollar. As of December 31, 2017, we were exposed to changes in exchange rates between the U.S.dollar and the Canadian dollar, Chinese Yuan, Indian Rupee, British Pound, and Euro. We hedge material foreign currency exchange rate exposures whenfeasible using forward contracts. These instruments are subject to fluctuations in foreign currency exchange rates and credit risk. Credit risk is managedthrough careful selection and ongoing evaluation of the financial institutions utilized as counter parties. Refer to Note 11, Financial Instruments, in theNotes to Consolidated Financial Statements for further discussion.Interest Rate SensitivityAs of December 31, 2017, there was $55.0 million outstanding and $69.7 million of available borrowing capacity under our credit facility. Ourinterest expense will fluctuate as the interest rate for the line of credit floats based, at our option, on the prime rate plus a margin or the one-month LIBOR rateplus a margin. Based on the $55.0 million outstanding on the line of credit as of December 31, 2017, an increase in the interest rate of 100 basis points wouldadd $550,000 of interest expense per year, which is not considered material to our financial position or results of operations.We had unrestricted cash and cash equivalents totaling $6.3 million at December 31, 2017 and $10.1 million at December 31, 2016. Theunrestricted cash and cash equivalents are held for working capital purposes. We do not enter into investments for trading or speculative purposes.24 Item 8.Financial Statements and Supplementary Data.PERFICIENT, INC.CONSOLIDATED BALANCE SHEETS December 31, 2017 2016 ASSETS (In thousands, except shareinformation) Current assets: Cash and cash equivalents $6,307 $10,113 Accounts receivable, net 112,194 103,702 Prepaid expenses 4,470 3,353 Other current assets 6,237 5,331 Total current assets 129,208 122,499 Property and equipment, net 7,145 8,888 Goodwill 305,238 275,205 Intangible assets, net 51,066 45,115 Other non-current assets 6,403 4,869 Total assets $499,060 $456,576 LIABILITIES AND STOCKHOLDERS’ EQUITY Current liabilities: Accounts payable $23,196 $18,416 Other current liabilities 38,077 27,637 Total current liabilities 61,273 46,053 Long-term debt 55,000 32,000 Other non-current liabilities 16,436 19,058 Total liabilities $132,709 $97,111 Commitments and contingencies (see Note 12) Stockholders’ equity: Common stock (par value $.001 per share; 100,000,000 shares authorized and 47,370,945 shares issued and 33,249,665shares outstanding as of December 31, 2017; 50,000,000 shares authorized and 45,895,086 shares issued and33,865,688 shares outstanding as of December 31, 2016) $47 $46 Additional paid-in capital 403,906 379,094 Accumulated other comprehensive loss (1,822) (2,743)Treasury stock, at cost (14,121,280 shares as of December 31, 2017; 12,029,398 shares as of December 31, 2016) (163,871) (126,442)Retained earnings 128,091 109,510 Total stockholders’ equity 366,351 359,465 Total liabilities and stockholders’ equity $499,060 $456,576 See accompanying notes to consolidated financial statements.25 PERFICIENT, INC.CONSOLIDATED STATEMENTS OF OPERATIONS Year Ended December 31, 2017 2016 2015 Revenues: (In thousands, except per share information) Services $434,253 $418,589 $411,469 Software and hardware 38,642 49,954 46,622 Reimbursable expenses 12,366 18,439 15,530 Total revenues 485,261 486,982 473,621 Cost of revenues (exclusive of depreciation and amortization, shown separately below): Cost of services 278,087 273,682 261,711 Software and hardware costs 33,295 43,581 41,170 Reimbursable expenses 12,366 18,439 15,530 Total cost of revenues 323,748 335,702 318,411 Selling, general, and administrative 108,192 101,264 99,963 Depreciation 4,722 4,867 4,496 Amortization 15,025 13,371 13,819 Acquisition costs 1,359 1,252 1,235 Adjustment to fair value of contingent consideration 3,235 (1,679) 445 Income from operations 28,980 32,205 35,252 Net interest expense 1,838 1,636 2,085 Net other (income) expense (1) 60 332 Income before income taxes 27,143 30,509 32,835 Provision for income taxes 8,562 10,050 9,828 Net income $18,581 $20,459 $23,007 Basic net income per share $0.56 $0.60 $0.69 Diluted net income per share $0.55 $0.58 $0.67 Shares used in computing basic net income per share 33,016 34,023 33,408 Shares used in computing diluted net income per share 34,066 35,001 34,324 See accompanying notes to consolidated financial statements.26 PERFICIENT, INC.CONSOLIDATED STATEMENTS OF COMPREHENSIVE INCOME(In thousands) Year Ended December 31, 2017 2016 2015 Net income $18,581 $20,459 $23,007 Other comprehensive income (loss), net of reclassification adjustments: Foreign benefit plan 88 (34) -

Description of Business and Principles of ConsolidationPerficient, Inc. (the “Company”) is an information technology consulting firm. The Company helps its clients use Internet-based technologies tomake their businesses more responsive to market opportunities and threats; strengthen relationships with customers, suppliers, and partners; improveproductivity; and reduce information technology costs. The Company designs, builds, and delivers solutions using a core set of middleware softwareproducts developed by third-party vendors. The Company’s solutions enable its clients to meet the changing demands of an increasingly global, Internet-driven, and competitive marketplace.The Company is incorporated in Delaware. The consolidated financial statements include the accounts of the Company and its wholly-ownedsubsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.2. Summary of Significant Accounting PoliciesUse of EstimatesThe preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimatesand assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financialstatements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates, and suchdifferences could be material to the financial statements.Revenue RecognitionService revenues are primarily derived from professional services provided on a time and materials basis. For time and material contracts, servicerevenues are recognized and billed by multiplying the number of hours expended in the performance of the contract by the established billing rates. For fixedfee projects, service revenues are generally recognized using an input method based on the ratio of hours expended to total estimated hours. Amountsinvoiced and collected in excess of revenues recognized are classified as deferred revenues. In conjunction with services provided, the Companyoccasionally receives referral fees under partner programs. These referral fees are recognized when earned and recorded within service revenues. Revenuesfrom software and hardware sales are generally recorded on a gross basis considering the Company’s role as a principal in the transaction. Revenues fromsales of third-party software-as-a-service arrangements where the Company is not the primary obligor are recorded on a net basis. On many projects theCompany is also reimbursed for out-of-pocket expenses including travel and other project-related expenses. These reimbursements are included as acomponent of revenues. We did not realize any profit on reimbursable expenses.Unbilled revenues represent the project time and expenses that have been incurred, but not yet billed to the client, prior to the end of the fiscalperiod. For time and materials projects, the client is invoiced for the amount of hours worked multiplied by the billing rates as stated in the contract. For fixedfee arrangements, the client is invoiced according to the agreed-upon schedule detailing the amount and timing of payments in the contract. Clients aretypically billed monthly for services provided during that month, but can be billed on a more or less frequent basis as determined by the contract. If the timeand expenses are worked/incurred and approved at the end of a fiscal period and the invoice has not yet been sent to the client, the amount is recorded asunbilled revenue once the Company verifies all other revenue recognition criteria have been met.Revenues are recognized when the following criteria are met: (1) persuasive evidence of the customer arrangement exists; (2) fees are fixed anddeterminable; (3) delivery and acceptance have occurred; and (4) collectability is deemed probable. The Company’s policy for revenue recognition ininstances where multiple deliverables are sold contemporaneously to the same customer is in accordance with the FASB Accounting Standards Codification(“ASC”) Subtopic 985-605, Software – Revenue Recognition, ASC Subtopic 605-25, Revenue Recognition – Multiple-Element Arrangements, and ASCSection 605-10-S99 (Staff Accounting Bulletin Topic 13, Revenue Recognition). Specifically, if the Company enters into contracts for the sale of servicesand software or hardware, then the Company evaluates whether each element should be accounted for separately by considering the following criteria: (1)whether the deliverables have value to the client on a stand-alone basis; and (2) whether delivery or performance of the undelivered item or items isconsidered probable and substantially in the control of the Company (only if the arrangement includes a general right of return related to the delivered item).Further, for sales of software and services, the Company also evaluates whether the services are essential to the functionality of the software and if it has fairvalue evidence for each deliverable. If the Company has concluded that the separation criteria are met, then it accounts for each deliverable in the transactionseparately, based on the relevant revenue recognition policies. Generally, all deliverables of the Company’s multiple element arrangements meet thesecriteria and are accounted for separately, with the arrangement consideration allocated among the deliverables using vendor specific objective evidence ofthe selling price. As a result, the Company generally recognizes software and hardware sales upon delivery to the customer and services consistent with thepolicies described herein.Further, delivery of software and hardware sales, when sold contemporaneously with services, can generally occur at varying times depending on thespecific client project arrangement. Delivery of services generally occurs over a period of time consistent with the timeline as outlined in the client contract.There are no significant cancellation or termination-type provisions for the Company’s software and hardware sales. Contracts for professionalservices provide for a general right, to the client or the Company, to cancel or terminate the contract within a given period of time (generally 10 to 30 days’notice is required). The client is responsible for any time and expenses incurred up to the date of cancellation or termination of the contract.The Company may provide multiple services under the terms of an arrangement and is required to assess whether one or more units of accounting arepresent. Service fees are typically accounted for as one unit of accounting, as fair value evidence for individual tasks or milestones is not available. TheCompany follows the guidelines discussed above in determining revenues; however, certain judgments and estimates are made and used to determinerevenues recognized in any accounting period. If estimates are revised, material differences may result in the amount and timing of revenues recognized for agiven period. Revenues are presented net of taxes assessed by governmental authorities. Sales taxes are generally collected and subsequently remitted on allsoftware and hardware sales and certain services transactions as appropriate.30 Allowance for Doubtful AccountsAn allowance for doubtful accounts is based upon specific identification of likely and probable losses. Each accounting period, accounts receivableis evaluated for risk associated with a client’s inability to make contractual payments, historical experience, and other currently available information.Stock-Based CompensationThe fair value of restricted stock awards are based on the value of the Company’s common stock on the date of the grant. Stock-based compensationis accounted for in accordance with ASC Topic 718, Compensation – Stock Compensation. Under this guidance, the Company recognizes share-basedcompensation ratably using the straight-line attribution method over the requisite service period, which is generally three years. In addition, pursuant to ASUNo. 2016-09, Improvements to Employee Share-Based Payment Accounting, the Company has continued to elect to estimate the amount of expectedforfeitures when calculating share-based compensation, instead of accounting for forfeitures as they occur.Income TaxesThe Company accounts for income taxes in accordance with ASC Subtopic 740-10, Income Taxes (“ASC Subtopic 740-10”), and ASC Section 740-10-25, Income Taxes – Recognition (“ASC Section 740-10-25”). ASC Subtopic 740-10 prescribes the use of the asset and liability method whereby deferredtax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and aremeasured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Deferred tax assets are subject to tests ofrecoverability. A valuation allowance is provided for such deferred tax assets to the extent realization is not judged to be more likely than not. ASC Section740-10-25 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken orexpected to be taken in a tax return. ASC Section 740-10-25 also provides guidance on derecognition, classification, treatment of interest and penalties, anddisclosure of such positions. On December 22, 2017, the U.S. government enacted the 2017 Tax Act. The 2017 Tax Act significantly revised the futureongoing U.S. corporate income tax by, among other things, lowering U.S. corporate income tax rates and implementing a territorial tax system. See Note 10,Income Taxes, for additional information regarding the 2017 Tax Act.Cash and Cash EquivalentsCash and cash equivalents consist of all cash balances and liquid investments with original maturities of three months or less.Property and EquipmentProperty and equipment are recorded at cost. Depreciation of property and equipment is computed using the straight-line method over the usefullives of the assets (generally one to seven years). Leasehold improvements are amortized over the shorter of the life of the lease or the estimated useful life ofthe assets.Goodwill and Intangible AssetsGoodwill represents the excess purchase price over the fair value of net assets acquired, or net liabilities assumed, in a business combination. Inaccordance with ASC Topic 350, Intangibles – Goodwill and Other (“ASC Topic 350”), the Company performs an annual impairment review in the fourthquarter and more frequently if events or changes in circumstances indicate that goodwill might be impaired. ASC Topic 350 permits an assessment ofqualitative factors to determine whether it is more likely than not that the fair value is less than the carrying amount of the Company before applying thequantitative goodwill impairment test. If it is more likely than not that the fair value is less than the carrying amount of the Company, the quantitativegoodwill impairment test will be conducted to detect and measure any impairment. Based upon the Company’s qualitative assessment, it is more likely thannot that the fair value of the Company is greater than its carrying amount. No impairment charges were recorded for 2017, 2016 or 2015.Other intangible assets include customer relationships, non-compete arrangements, trade names, customer backlog, and internally developedsoftware, which are being amortized over the assets’ estimated useful lives using the straight-line method. Estimated useful lives range from less than one yearto ten years. Amortization of customer relationships, non-compete arrangements, trade names, customer backlog, and internally developed software isconsidered an operating expense and is included in “Amortization” in the accompanying Consolidated Statements of Operations. The Company periodicallyreviews the estimated useful lives of its identifiable intangible assets, taking into consideration any events or circumstances that might result in a lack ofrecoverability or revised useful life. Other intangible assets are evaluated for impairment upon the occurrence of events or changes in circumstancesindicating that the carrying amount of an asset may not be recoverable. No impairment of intangible assets were recorded for 2017, 2016 or 2015.Purchase Accounting and Related Fair Value MeasurementsThe Company allocates the purchase price, including contingent consideration, of our acquisitions to the assets and liabilities acquired, includingidentifiable intangible assets, based on their respective fair values at the date of acquisition. Such fair market value assessments are primarily based on third-party valuations using assumptions developed by management that require significant judgments and estimates that can change materially as additionalinformation becomes available. The purchase price allocated to intangibles is based on unobservable factors, including but not limited to, projectedrevenues, expenses, customer attrition rates, royalty rates, a weighted average cost of capital, among others. The weighted average cost of capital uses amarket participant’s cost of equity and after-tax cost of debt and reflects the risks inherent in the cash flows. The approach to valuing the contingentconsideration associated with the purchase price also uses similar unobservable factors such as; projected revenues and expenses over the term of thecontingent earn-out period, discounted for the period over which the contingent considerations is measured. Based upon these assumptions, the contingentconsideration is then valued using a Monte Carlo simulation. The Company finalizes the purchase price allocation within 12 months of the acquisition dateas certain initial accounting valuation estimates are finalized.Financial InstrumentsCash equivalents, accounts receivable, accounts payable, and other accrued liabilities are stated at amounts which approximate fair value due to thenear term maturities of these instruments. The Company’s long-term debt balance approximates fair market value.The Company, when deemed appropriate, uses derivatives as a risk management tool to mitigate the potential impact of foreign currency exchangerate risk. Both the gain or loss on derivatives not designated as hedging instruments and the offsetting loss or gain on the hedged item attributable to thehedged risk are recognized in current earnings. All derivatives are carried at fair value in the consolidated balance sheets. See Note 11, Financial Instruments, for additional information regarding our derivative financial instruments.31 Treasury StockThe Company uses the cost method to account for repurchases of its own stock.Segment and Geographic InformationThe Company operates as one reportable operating segment according to ASC Topic 280, Segment Reporting, which establishes standards for theway that business enterprises report information about operating segments. The chief operating decision maker formulates decisions about how to allocateresources and assess performance based on consolidated financial results. The Company also has one reporting unit for purposes of the goodwill impairmentanalysis discussed above. Approximately 98% of our revenues were derived from clients in the United States during each of the years ended December 31,2017, 2016 and 2015. Less than 2% of the Company’s non-current assets were located outside the United States for each of the years ended December 31,2017 and 2016.Recent Accounting PronouncementsIn May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount ofrevenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU No. 2014-09 replaced most existing revenuerecognition guidance in U.S. GAAP. In 2015, the FASB deferred the effective date of ASU No. 2014-09 by one year. In 2016, the FASB issued ASU No. 2016-08, Principal versus Agent Considerations, ASU No. 2016-10, Identifying Performance Obligations and Licensing, ASU No. 2016-12, Narrow-ScopeImprovements and Practical Expedients and ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts withCustomers, all of which further amended ASU No. 2014-09. The Company adopted the standard on January 1, 2018 using the modified retrospective methodwhich requires a cumulative-effect adjustment to the opening balance of retained earnings within stockholders’ equity, as will be fully presented in theCompany’s Quarterly Report on Form 10-Q for the three months ended March 31, 2018. The Company has determined that the most significant impact uponadoption is to third-party software and hardware revenue, which has primarily been recorded on a gross basis as the principal in the transaction throughDecember 31, 2017 and will be presented on a net basis as the agent as of January 1, 2018. Had the Company historically presented third-party software andhardware revenues on a net basis, software and hardware revenues would have been $5.3 million, $6.4 million, and $5.5 million for the years ended December31, 2017, 2016, and 2015, respectively. As the Company adopted ASU No. 2014-09 using the modified retrospective method, the gross versus netpresentation will not impact the historical presentation but will impact the 2018 presentation. Additionally, as the agent, revenue from multi-year sales ofthird-party software and support will be recognized upfront as the performance obligation is fulfilled, rather than annually as invoiced to the customer. Theimpact from this timing change is expected to be immaterial. Variable consideration related to service contracts, such as volume discounts and holdbacks,may be recognized earlier under the new standard, and the Company is currently evaluating the impact of this change on contracts that are open as ofDecember 31, 2017. The adoption of ASU No. 2014-09 and its amendments will also result in additional disclosures around the nature and timing ofperformance obligations, contract costs, and deferred revenue, as well as significant judgments and practical expedients used by the Company.In February 2016, the FASB issued ASU No. 2016-02, Leases, which supersedes ASC Topic 840, Leases, and creates a new topic, ASC Topic 842,Leases. This update requires lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12months on its balance sheet. The update also expands the required quantitative and qualitative disclosures surrounding leases. This update is to becomeeffective for the Company on January 1, 2019, with earlier application permitted. This update will be applied using a modified retrospective transitionapproach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. While theCompany is currently assessing the impact ASU No. 2016-02 will have on its consolidated financial statements, the Company expects the primary impactupon adoption will be the recognition, on a discounted basis, of its minimum commitments under noncancellable operating leases on its consolidatedbalance sheets resulting in the recording of right of use assets and lease obligations. Current minimum commitments under noncancellable operating leasesare disclosed in Note 12, Commitments and Contingencies.In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments. This update eliminates thediversity in practice related to the classification of certain cash receipts and payments for debt prepayment or extinguishment costs, the maturing of a zerocoupon bond, the settlement of contingent liabilities arising from a business combination, proceeds from insurance settlements, distributions from certainequity method investees and beneficial interests obtained in a financial asset securitization. ASU No. 2016-15 designates the appropriate cash flowclassification, including requirements to allocate certain components of these cash receipts and payments among operating, investing and financingactivities. This update is to become effective for the Company on January 1, 2018 and requires using a retrospective approach. The Company elected to earlyadopt this update retrospectively on January 1, 2017 since the Company was already in compliance with the new standard. The adoption of ASU No. 2016-15 did not have a material impact on the Company’s consolidated financial statements.In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. This update eliminates Step 2 from the goodwillimpairment test which compares the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. ASU No. 2017-04 does notmake any changes to the impairment indicators or aspects of the qualitative assessment. This update is to become effective for the Company on January 1,2020 and requires using a prospective approach. Early adoption is permitted beginning with interim or annual goodwill impairment tests performed ontesting dates on or after January 1, 2017. The Company elected to early adopt this update prospectively on January 1, 2017. The adoption of ASU No. 2017-04 did not have an impact on the Company’s consolidated financial statements.3. Net Income Per ShareBasic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of common sharesoutstanding during the period. Diluted earnings per share includes the weighted average number of common shares outstanding and the number of equivalentshares which would be issued related to the stock options, unvested restricted stock, and warrants using the treasury method, unless such additionalequivalent shares are anti-dilutive.The following table presents the calculation of basic and diluted net income per share (in thousands, except per share information): Year Ended December 31, 2017 2016 2015 Net income $18,581 $20,459 $23,007 Basic: Weighted-average shares of common stock outstanding 33,016 34,023 33,408 Shares used in computing basic net income per share 33,016 34,023 33,408 Effect of dilutive securities: Restricted stock subject to vesting 488 493 466 Contingently issuable shares (1) - 2 2 Shares issuable for acquisition consideration (2) 562 483 448 Shares used in computing diluted net income per share 34,066 35,001 34,324 Basic net income per share $0.56 $0.60 $0.69 Diluted net income per share $0.55 $0.58 $0.67 Anti-dilutive options and restricted stock not included in the calculation of diluted net income pershare 88 - 28 (1)For the year ended December 31, 2016, this represents the shares issued to Zeon Solutions Incorporated and certain related entities (collectively,“Zeon”) pursuant to the Asset Purchase Agreement.

Concentration of Credit Risk and Significant CustomersCash and accounts receivable potentially expose the Company to concentrations of credit risk. Cash is placed with highly rated financialinstitutions. The Company provides credit, in the normal course of business, to its customers. The Company generally does not require collateral or up-frontpayments. The Company performs periodic credit evaluations of its customers and maintains allowances for potential credit losses. Customers can be deniedaccess to services in the event of non-payment. During 2017, a substantial portion of the services the Company provided were built on IBM, Oracle, andMicrosoft platforms, among others, and a significant number of the Company’s clients are identified through joint selling opportunities conducted with andthrough sales leads obtained from the relationships with these vendors. Due to the Company’s significant fixed operating expenses, the loss of sales to anysignificant customer could negatively impact net income and cash flow from operations. However, the Company has remained relatively diversified, with itslargest customer only representing approximately 5% of total revenues excluding reimbursable expenses for the year ended December 31, 2017,approximately 6% of total revenues excluding reimbursable expenses for the year ended December 31,2016, and approximately 4% of total revenuesexcluding reimbursable expenses for the year ended December 31, 2015.5. Employee Benefit PlansThe Company has a qualified 401(k) profit sharing plan available to full-time employees who meet the plan’s eligibility requirements. This definedcontribution plan permits employees to make contributions up to maximum limits allowed by the Internal Revenue Code of 1986, as amended (the “Code”).The Company, at its discretion, matches a portion of the employee’s contribution under a predetermined formula based on the level of contribution and yearsof service. For 2017, the Company made matching contributions of 50% (25% in cash and 25% in Company stock) of the first 6% of eligible compensationdeferred by the participant. The Company recognized $4.9 million, $4.8 million, and $4.6 million of expense for the matching cash and Company stockcontribution in 2017, 2016, and 2015, respectively. All matching contributions vest over a three-year period of service.The Company has a nonqualified deferred compensation plan for certain U.S. personnel. The plan is designed to allow eligible participants toaccumulate additional income through elective deferrals of compensation which will be paid in the future. As of December 31, 2017 and 2016, the deferredcompensation liability balance was $4.7 million and $3.9 million, respectively. The Company funds the deferred compensation plan through company-owned life insurance (“COLI”) policies. During the year ended December 31, 2016, the Company settled its current COLI policies and funded new COLIpolicies with a different insurance provider.In accordance with Indian law, the Company provides certain defined benefit plans covering substantially all of its Indian employees. The gratuityplan provides a lump-sum payment to vested employees upon retirement or termination of employment in an amount based on each employee’s salary andduration of employment with the Company. The leave encashment plan requires the Company to pay employees leaving the Company a specific formulataking into account earned leaves up to a certain maximum and the employee’s most recent salary. The annual projected cost of these defined benefit plans isactuarially determined. As of December 31, 2017 and 2016, the defined benefit plan liability, which is unfunded was immaterial.32 6.

However,during the second quarter of 2017, the Company determined that as a result of changes in the business and macroeconomic environment, the foreign earningsof the Company’s Chinese subsidiary were no longer permanently reinvested, and the Company repatriated $4.8 million of cash in June 2017 and anadditional $4.8 million of cash in July 2017. A provision for the expected current and deferred taxes on repatriation of these earnings was recorded as adiscrete item in the amount of $2.5 million during the second quarter of 2017. Approximately $1.6 million of this provision was reversed during the fourthquarter of 2017 due to the adoption of the 2017 Tax Act. Management intends to continue to permanently reinvest all other remaining current and priorearnings in its other foreign subsidiaries.Excluding China, foreign unremitted earnings of entities not included in the United States tax return have been included in the consolidatedfinancial statements without giving effect to the United States taxes that may be payable on distribution to the United States because it is not anticipatedsuch earnings will be remitted to the United States. Under current applicable tax laws, if the Company elects to remit some or all of the funds it has designatedas indefinitely reinvested outside the United States, the amount remitted would be subject to applicable non-U.S. withholding taxes. As of December 31,2017, the aggregate unremitted earnings of the Company’s foreign subsidiaries for which a deferred income tax liability has not been recorded wasapproximately $4.9 million, and the unrecognized deferred tax liability on unremitted earnings was approximately $0.2 million.Under the provisions of the ASC Section 740-10-25, Income Taxes - Recognition, the Company had an unrecognized tax benefit of $2.7 and $1.2million as of December 31, 2017 and 2016, respectively.

The 2017 Tax Act significantly revised the future ongoing U.S. corporateincome tax by, among other things, lowering U.S. corporate income tax rates and implementing a territorial tax system.There are certain transitional impacts of the 2017 Tax Act which affected the Company’s tax provision during the fourth quarter of 2017. As part ofthe transition to the new territorial tax system, the 2017 Tax Act imposed a one-time repatriation tax on deemed repatriation of historical earnings of foreignsubsidiaries, which produced a $1.1 million tax expense payable over eight years. As a result, a $0.1 million current liability and a $1.0 million non-currentliability were recorded in the Company’s consolidated financial statements during the fourth quarter of 2017. The reduction of the U.S. corporate tax ratecaused the Company to adjust its U.S. deferred tax assets and liabilities to the lower federal base rate of 21%. The reduction in the corporate tax rate resultedin a provisional net tax credit of $3.3 million for the fourth quarter of 2017. In addition, as a result of the 2017 Tax Act, changes to the net tax cost of certainChina dividends repatriated during 2017 created a $1.6 million tax credit during the fourth quarter of 2017.The changes included in the 2017 Tax Act are broad and complex. The final transition impacts of the 2017 Tax Act may differ from the aboveestimate, possibly materially, due to, among other things, changes in interpretations of the 2017 Tax Act, any legislative action to address questions that arisebecause of the 2017 Tax Act, any changes in the accounting standards for income taxes or related interpretations in response to the 2017 Tax Act, or anyupdates or changes to estimates the Company has utilized to calculate the transition impacts, including impacts from changes to current year earningsestimates and foreign exchange rates of foreign subsidiaries. There were no specific impacts of the 2017 Tax Act that could not be reasonably estimatedwhich the Company accounted for under prior tax law. However, the SEC has issued rules that would allow for a measurement period of up to one year afterthe enactment date of the 2017 Tax Act to finalize the recording of the related tax impacts. Based on a continued analysis of the estimates and furtherguidance on the application of the law, it is anticipated that additional revisions may occur throughout the allowable measurement period. We currentlyanticipate finalizing and recording any resulting adjustments within a year of the enactment date.39 11. Financial InstrumentsIn the normal course of business, the Company uses derivative financial instruments to manage foreign currency exchange rate risk. Currencyexposure is monitored and managed by the Company as part of its risk management program which seeks to reduce the potentially adverse effects that marketvolatility could have on operating results. The Company’s derivative financial instruments consist of non-deliverable foreign currency forward contracts.Derivative financial instruments are neither held nor issued by the Company for trading purposes.Derivatives Not Designated as Hedging InstrumentsBoth the gain or loss on the derivatives not designated as hedging instruments and the offsetting loss or gain on the hedged item attributable to thehedged risk are recognized in current earnings. Realized gains or losses and changes in the estimated fair value of foreign currency forward contracts thathave not been designated as hedges were a net gain of $0.1 million during the year ended December 31, 2017. A net loss of $0.3 million was recognizedduring the year ended December 31, 2016. Gains and losses on these contracts are recorded in net other income (expense) and net interest expense in theConsolidated Statements of Operations and are offset by losses and gains on the related hedged items.The notional amounts of the Company’s derivative instruments outstanding were as follows (in thousands): December 31, 2017 2016 Derivatives not designated as hedges Foreign exchange contracts $3,979 $4,541 Total derivatives not designated as hedges $3,979 $4,541 Fair Value of Derivative InstrumentsThe authoritative guidance defines fair value as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability inan orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a fair value hierarchy that isintended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs tovaluation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participantswould use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’spricing based upon its own market assumptions.The fair value hierarchy consists of the following three levels:•Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities.•Level 2 – Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities inmarkets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principallyfrom or corroborated by observable market data.•Level 3 – Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.The Company estimates the fair value of each foreign exchange forward contract by using present value of expected cash flows. This considers thedifference between the current market forward price and contracted forward price for each foreign exchange contract and applies the difference in the rates toeach outstanding contract. Valuations for all derivatives fall within Level 2 of the GAAP valuation hierarchy. The fair value of the Company’s derivativeinstruments outstanding as of December 31, 2017 was immaterial.Derivatives may give rise to credit risks from the possible non-performance by counterparties. Credit risk is generally limited to the fair value ofthose contracts that are favorable to us. The Company has limited its credit risk by entering into derivative transactions only with highly-rated globalfinancial institutions, limiting the amount of credit exposure with any one financial institution and conducting ongoing evaluation of the creditworthiness ofthe financial institutions with which the Company does business.The Company utilizes standard counterparty master agreements containing provisions for the netting of certain foreign currency transactionobligations and for the set-off of certain obligations in the event of an insolvency of one of the parties to the transaction. Within the Consolidated BalanceSheets, the Company records derivative assets and liabilities at fair value.The carrying value of cash and cash equivalents, accounts receivable, accounts payable, current liabilities and the revolving line of creditapproximate fair value because of the short maturity of these instruments.40 12. Commitments and ContingenciesFrom time to time the Company is involved in legal proceedings, claims and litigation related to employee claims, contractual disputes and taxes inthe ordinary course of business. Although the Company cannot predict the outcome of such matters, currently the Company has no reason to believe thedisposition of any current matter could reasonably be expected to have a material adverse impact on the Company’s financial position, results of operationsor the ability to carry on any of its business activities.In June 2016, the Company entered into an agreement to purchase software licenses for internal use payable over a two-year period. As a result, theCompany has recorded $0.8 million in “Other current liabilities” in the Consolidated Balance Sheet as of December 31, 2017.Certain of the Company’s operating leases contain predetermined fixed escalations of minimum rentals during the original lease terms. For theseleases, the Company recognizes the related rental expense on a straight-line basis over the life of the lease and records the difference between the amountscharged to operations and amounts paid as accrued rent expense.The Company leases office space and certain equipment under various operating lease agreements. The Company has the option to extend the termof certain lease agreements. Future minimum commitments under these lease agreements as of December 31, 2017 are as follows (in thousands): OperatingLeases 2018 $6,535 2019 6,539 2020 6,072 2021 4,595 2022 2,773 Thereafter 2,970 Total minimum lease payments $29,484 Rent expense for the years ended December 31, 2017, 2016, and 2015 was approximately $7.9 million, $7.5 million, and $6.5 million, respectively.13.

A company’s internal controlover financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairlyreflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permitpreparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are beingmade only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention ortimely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate./s/ KPMG LLPWe have served as the Company’s auditor since 2007.St. Louis, MissouriMarch 1, 201843 Item 9.Changes In and Disagreements With Accountants on Accounting and Financial Disclosure.None.Item 9A.Controls and Procedures.Evaluation of Disclosure Controls and ProceduresWe have established disclosure controls and procedures to ensure that material information relating to the Company, including its consolidatedsubsidiaries, is made known to the officers who certify the Company’s financial reports and to other members of senior management and the Board ofDirectors.We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s reports underthe Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such informationis accumulated and communicated to management, including the principal executive officer and principal financial officer of the Company, as appropriate,to allow timely decisions regarding required disclosure.
