In some cases, you can identify these so-calledforward-looking statements by words like “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” or“continue” or the negative of those words and other comparable words. You should be aware that those statements only reflect our predictions and are subjectto risks and uncertainties. Actual events or results may differ substantially. Important factors that could cause our actual results to be materially different fromthe forward-looking statements include (but are not limited to) the following: (1)the impact of the general economy and economic and political uncertainty on our business;(2)risks associated with potential changes to federal, state, local and foreign laws, regulations, and policies;(3)risks associated with the operation of our business generally, including:a. client demand for our services and solutions;b. maintaining a balance of our supply of skills and resources with client demand;c. effectively competing in a highly competitive market;d. protecting our clients’ and our data and information;e. risks from international operations including fluctuations in exchange rates;f. changes to immigration policies;g. obtaining favorable pricing to reflect services provided;h. adapting to changes in technologies and offerings;i. risk of loss of one or more significant software vendors;j. making appropriate estimates and assumptions in connection with preparing our consolidated financial statements;k. maintaining effective internal controls; andl. changes to tax levels, audits, investigations, tax laws or their interpretation;(4)risks associated with managing growth organically and through acquisitions;(5)risks associated with servicing our debt, the potential impact on the value of our common stock from the conditional conversion features of our debtand the associated convertible note hedge transactions;(6)legal liabilities, including intellectual property protection and infringement or the disclosure of personally identifiable information; and(7)the risks detailed from time to time within our filings with the Securities and Exchange Commission (the “SEC”).

We also serve as a sales channel for our partners, helping them market and sell theirsoftware products.

As of December 31, 2018, we had 58 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.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, 2018, we had 3,060 employees, 2,556 of which were billable (excluding 239 billable subcontractors) and 504 of which wereinvolved in sales, administration, and marketing. None of our employees are represented by a collective bargaining agreement, and we have neverexperienced a strike or similar work stoppage. We are committed to the continued development of our employees.Sales and Marketing. As of December 31, 2018, we had a 108-person direct solutions-oriented sales force. We reward our sales force for developingand maintaining relationships with our clients, seeking follow-up engagements, and leveraging those relationships to forge new relationships in differentareas of the business and with our clients’ business partners. Approximately 79% of our services revenues are executed by our direct sales force.

Thesecompanies are key vendors of open standards-based software commonly referred to as middleware application servers, enterprise application integrationplatforms, business process management, cloud computing applications, business activity monitoring and business intelligence applications, and enterpriseportal server software. 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 are dedicated to hiring, developing, and retaining experienced, motivated technology professionals who combine a depth ofunderstanding of current Internet and legacy technologies with the ability to implement complex and cutting-edge solutions. We believe in an employee-centered environment that is built on a culture of respect.6Retention.

We focus on a core set of digital experience, business optimization, and industry solutions, applications, and software platforms and our commitmentto our employees’ career development through continued training and advancement opportunities sets us apart as an employer of choice.Compensation.

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.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 and political conditions and the effects of theseconditions on our clients’ businesses and levels of business activity.Global macroeconomic and political conditions affect our clients’ businesses and the markets they serve. Developments such as economicdownturns, trade disputes, recessions, instability and inflationary risks in the United States, Europe, Canada, China and India, among other developments,may have an adverse effect on our clients’ businesses and, consequently, on our results of operations, revenue growth and profitability.Volatile, negative or uncertain economic and political conditions in the markets we serve have undermined, and could in the future undermine,business confidence and cause our clients to reduce or defer their spending on new technologies or initiatives or terminate existing contracts, which wouldnegatively affect 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. Differingeconomic and political conditions and patterns of economic growth and contraction in the geographical regions in which we operate and the markets weserve have affected, and may in the future affect, demand for our services. For the year ended December 31, 2018, 99% of our revenues were derived from ourclients in North America. Weakening demand in this market could have a material adverse effect on our results of operations. Ongoing economic andpolitical volatility and uncertainty affects our business in a number of other ways, including making it more difficult to accurately forecast client demandbeyond the short term and effectively build our revenue and resource plans, particularly in consulting. This could result, for example, in us not having thelevel of appropriate personnel where they are needed or having to use involuntary terminations as means to keep our supply of skills and resources inbalance.Economic and political volatility and uncertainty is particularly challenging because it may take some time for the effects and resulting changes indemand patterns to manifest themselves in our business and results of operations. Changing demand patterns from economic and political volatility anduncertainty could have a significant negative impact on our results of operations.We face risks associated with potential changes to federal, state, local and foreign laws, regulations and policies.7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, international trade, laborand employment law, immigration and health care, which individually or in the aggregate could materially and adversely affect our business, results ofoperations 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 economic andpolitical conditions have adversely affected, and could in the future adversely affect, client demand for our services and solutions. In addition, developmentsin the markets we serve, which may be rapid, could shift demand to services and solutions where we are less competitive, or might require significantinvestment by us to upgrade, enhance or expand our services and solutions to meet that demand. Companies in the markets we serve sometimes seek toachieve economies of scale and other synergies by combining with or acquiring other companies. If one of our current clients merges or consolidates with acompany that relies on another provider for its consulting, systems integration and technology, or outsourcing services, we may lose work from that client orlose the opportunity to gain additional work if we are not successful in generating new opportunities from the merger or consolidation. Many of ourconsulting contracts are less than 12 months in duration, and often contain 10 to 30 day termination provisions. If a client is dissatisfied with our services andwe are unable to effectively respond to its needs, the client might terminate existing contracts, or reduce or eliminate spending on the services and solutionswe provide. Additionally, a client could choose not to retain us for additional stages of a project, try to renegotiate the terms of its contract or cancel or delayadditional planned work. When contracts are terminated or not renewed, we lose the anticipated revenues, and it may take significant time to replace the lostrevenues or we may be unsuccessful in our attempt to recover such revenues. Consequently, our results of operations in subsequent periods could bematerially lower than expected. The specific business or financial condition of a client, changes in management and changes in a client’s strategy also are allfactors that can result in terminations, cancellations or delays. It could also result in pressure to reduce the cost of our services.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 our8work profitably could suffer. If the utilization rate of our professionals is too high, it could have an adverse effect on employee engagement and attrition, thequality of the work performed and our ability to staff projects. If our utilization rate is too low, our profitability and the engagement of our employees couldsuffer. The costs associated with recruiting and training employees are significant. An important element of our global business model is the deployment ofour 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 increasedregulation of immigration or work visas, including limitations placed on the number of visas granted, limitations on the type of work performed or location inwhich it can be performed, and new or higher minimum salary requirements, it could be more difficult to staff our employees on client engagements andcould 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 orgeographic locations. In these situations, we must evaluate voluntary attrition and use reduced levels of new hiring and increased involuntary terminations asmeans to keep our supply of skills and resources in balance with client demand in those markets.The markets in which we operate are highly competitive, and we might not be able to compete effectively.The markets in which we operate are highly competitive, ever evolving, and subject to rapid technological change. Our competitors include: largemultinational providers that offer some or all of the services that we do; offshore service providers in lower-cost locations that offer services similar to thosewe offer, often at highly competitive prices and on more aggressive contractual terms; niche solution and service providers or local competitors that competewith us in a specific geographic market, industry segment or service area, including companies that provide new or alternative products, service or deliverymodels; accounting firms that are expanding or building their capabilities to provide certain consulting services, including through acquisitions; and in-house departments of large corporations that use their own resources, rather than engage an outside firm for the types of services we 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.9We could have significant liability or our reputation could be damaged if we fail to protect client and Company data or information systems or if ourinformation systems 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 or human error could lead to shutdowns or disruptions of oursystems and potential unauthorized disclosure of confidential information. There has been a global increase in information technology security threats andincreasingly sophisticated cyber attacks. Given the uncertainty of such attacks, our infrastructure may be vulnerable to attacks and disputes. In providingservices to clients, we are also required at times to manage, utilize, and store sensitive or confidential client or employee data. As a result, we are subject tonumerous laws and regulations designed to protect this information, such as various U.S. federal and state laws and foreign laws governing the protection ofpersonally identifiable information. If any person, including any of our employees, negligently disregards or intentionally breaches our established controlswith respect to such data or otherwise mismanages or misappropriates that data, we could be subject to monetary damages, regulatory enforcement actions,fines, and/or criminal prosecution. Unauthorized disclosure of sensitive or confidential client or employee data, whether through systems failure, human erroror negligence, cyber attacks, security breaches, fraud or misappropriation could damage our reputation and cause us to lose clients. Similarly, unauthorizedaccess to or through our information systems or those we develop for our clients, whether by our employees or third parties, could result in negative publicity,significant remediation costs, legal liability, and damage to our reputation and could have a material adverse 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 to security breaches, cyber-attacks and other relatedbreaches.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.Servicing our debt may require a significant amount of cash. We may not have sufficient cash flow from our business to pay our indebtedness, and wemay not have the ability to raise the funds necessary to settle for cash conversions of the Notes or to repurchase the Notes for cash upon a fundamentalchange, which could adversely affect our business and results of operations.In September 2018, we issued $143.8 million in aggregate principal amount of 2.375% Convertible Senior Notes Due 2023 (the “Notes”) in aprivate offering. The Notes bear interest at a rate of 2.375% per year. Interest is payable in cash on March 15 and September 15 of each year, beginning March15, 2019. Our ability to make payments of the principal, to pay interest on or to refinance our indebtedness, including the Notes, depends on our futureperformance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flows fromoperations in the future that are sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flows, we maybe required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional debt financing or equity capital on terms thatmay be onerous or highly dilutive. Our ability to refinance any future indebtedness will depend on the capital markets and our financial condition at suchtime. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debtobligations.Holders of the Notes have the right to require us to repurchase their notes upon the occurrence of a fundamental change (as defined in the indenturegoverning the Notes (the “Indenture”)) at a cash repurchase price equal to the principal amount of the10Notes to be repurchased, plus accrued and unpaid interest, if any. Upon conversion, unless we elect to deliver solely shares of our common stock to settlesuch conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the Notes beingconverted. We may not have enough available cash or be able to obtain financing at the time we are required to make repurchases in connection with suchconversion and our ability to pay may additionally be limited by law, by regulatory authority or by agreements governing our future indebtedness. Ourfailure to repurchase the Notes at a time when the repurchase is required by the Indenture or to pay any cash payable on future conversions as required by theIndenture would constitute a default under the Indenture. A default under the Indenture or the fundamental change itself could also lead to a default underagreements governing our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or graceperiods, we may not have sufficient funds to repay the indebtedness and repurchase the Notes or make cash payments upon conversions thereof. The conditional conversion feature of the Notes, if triggered, may adversely affect our financial condition and operating results.In the event the conditional conversion feature of the Notes is triggered, holders of Notes will be entitled to convert the Notes at any time duringspecified periods at their option. If one or more holders elect to convert their Notes, unless we elect to satisfy our conversion obligation by delivering solelyshares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of ourconversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert theirNotes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Notes as a current rather thanlong-term liability, which would result in a material reduction of our net working capital.Transactions relating to our Notes may affect the value of our common stock.Our Notes may become in the future convertible at the option of their holders under certain circumstances. If holders of our Notes elect to converttheir notes, we may settle our conversion obligation by delivering to them a significant number of shares of our common stock, which would cause dilutionto our existing stockholders.In addition, in connection with the issuance of the Notes, we entered into privately negotiated convertible note hedge transactions (the “NotesHedges”) with certain of the initial purchasers or their respective affiliates and/or other financial institutions (the “Option Counterparties”). If the Companyexercises the Notes Hedges, the aggregate amount of cash received from the Option Counterparties will cover the aggregate amount of cash that the Companywould be required to pay to the holders of the Notes, less the principal amount thereof. Also in connection with the issuance of the Notes, we sold net-share-settled warrants (the “Notes Warrants”) in privately negotiated transactions with the Option Counterparties. The Notes Hedges and Notes Warrants areexpected generally to reduce the potential dilution to our common stock upon any conversion or settlement of the Notes and/or offset any cash payments weare required to make in excess of the principal amount of converted Notes, as the case may be, with such reduction and/or offset subject to a cap.We are subject to counterparty risk with respect to the Notes Hedges.The Option Counterparties are financial institutions, and we will be subject to the risk that one or more of the Option Counterparties might defaultunder their respective Note Hedges. Our exposure to the credit risk of the Option Counterparties will not be secured by any collateral. Global economic andpolitical conditions could result in the actual or perceived failure or financial difficulties of financial institutions. If any Option Counterparty becomessubject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under ourtransactions with such Option Counterparty.Our exposure will depend on many factors, but, generally, the increase in our exposure will be correlated to the increase in the market price and inthe volatility of our common stock. In addition, upon a default by any Option Counterparty, we may suffer adverse tax consequences and more dilution thanwe currently anticipate with respect to our common stock. We can provide no assurances as to the financial stability or viability of any of the OptionCounterparties.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 operations11in these countries or with international operations generally. We may also face difficulties integrating new facilities in different countries into our existingoperations, as well as integrating employees that we hire in different countries into our existing corporate culture.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 8% 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 under the current administration of the U.S. federal government or disruption as a result of government shutdowns. If we areunable to obtain all of the H1-B visas for which we apply, our growth may be hindered.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 and12cost necessary to deliver such services and solutions, which might be based on limited data and could turn out to be materially inaccurate. If we do notaccurately estimate the level of effort or cost, our contracts could yield lower profit margins than planned, or be unprofitable. We could face greater risk whennegotiating fees for our contracts that involve the coordination of operations and workforces in multiple locations and/or utilizing workforces with differentskill sets and competencies. There is a risk that we will underprice our contracts, fail to accurately estimate the costs of performing the work, or fail toaccurately assess the risks associated with potential contracts. In particular, any increased or unexpected costs, delays or failures to achieve anticipated costsavings, or unexpected risks we encounter in connection with the performance of services, including those caused by factors outside our control, could makethese contracts less profitable or unprofitable, which could have 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, Microsoft, Adobe, Oracle, Salesforce, Pivotal and Sitecore. 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. 13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(including meritless claims) asserted against us. These claims may harm our reputation, cause our management to expend significant time in connection withany defense, and cost us money. We may be required to indemnify clients for any expense or liabilities they incur resulting from claimed infringement andthese expenses could exceed 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, and harmful to our reputation.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, purchase14accounting related fair value measurements, contingent consideration, fair value of convertible debt and income taxes. We base our estimates on historicalexperience, contractual commitments and on various other assumptions that we believe to be reasonable under the circumstances at the time they are made.These estimates and assumptions involve the use of our judgment and can be subject to significant uncertainties, some of which are beyond our control. If ourestimates, or the assumptions underlying such estimates, are not correct, actual results may differ materially from our estimates, and we may need to, amongother things, adjust revenues or accrue additional charges that could adversely affect our results of operations.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.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 13, Income Taxes, in the Notes to 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, treaties, or regulations, or their interpretation or enforcement, may be unpredictable and could materially adversely affect our taxposition.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 Canadian dollar, Indian rupee, Chinese yuan, 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 pound15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 agreater degree from such a decrease and can, as a result, deliver services at a lower cost. In addition, our currency hedging activities are themselves subject torisk. These include risks related to counterparty performance under hedging contracts, risks related to ineffective hedges and risks related to currencyfluctuations. We also face risks that extreme economic conditions, political instability, hostilities or natural disasters could impact or perhaps eliminate theunderlying exposures that we are hedging. Such an event could lead to losses being recognized on the currency hedges then in place that are not offset byanticipated changes 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.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;•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;16•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;•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.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, 2018, we had unrestricted cash and cash equivalents totaling $45.0 million and a borrowing capacity of $125.0 million, with$124.8 million unused capacity available, and a commitment from our lenders to increase our borrowing capacity by $75.0 million. Of the $45.0 million ofcash and cash equivalents at December 31, 2018, $5.8 million was held by our Canadian, Indian and United Kingdom subsidiaries and is considered to beindefinitely reinvested in those operations. As of December 31, 2018, $1.3 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 31% 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, Delaware law and certain provisions of our convertible notes could make it difficult for a third party to acquire us, even if doing sowould be beneficial to our stockholders. Our certificate of incorporation and bylaws may discourage, delay, or prevent a merger or acquisition that astockholder may consider favorable by authorizing the issuance of “blank check” preferred stock. In addition, provisions of the Delaware GeneralCorporation Law also restrict some business combinations with interested stockholders. These provisions are intended to encourage potential acquirers tonegotiate with us and allow the Board of Directors the opportunity to consider alternative proposals in the interest of maximizing stockholder value.Additionally, certain provisions of our convertible notes could make it more difficult or more expensive for a third party to acquire us. These provisions mayalso discourage acquisition proposals, or delay or prevent a change in control, which could harm our stock price.Item 1B.Unresolved Staff Comments.None.17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.18PART IIItem 5.Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of EquitySecurities.Our common stock is quoted on The Nasdaq Global Select Market under the symbol “PRFT.” There were approximately 402 stockholders of recordof our common stock as of February 14, 2019, including 347 restricted account holders.We have never declared or paid any cash dividends on our common stock. Our credit facility currently restricts the payment of cash dividends. SeeNote 12, Long-term Debt, in the Notes to Consolidated Financial Statements for further information regarding the restrictions. Any future determination as tothe declaration and payment of dividends will be made at the discretion of our board of directors and will depend on our earnings, operating and financialcondition, capital requirements and other factors deemed relevant by our board of directors, including the applicable requirements of the Delaware GeneralCorporation 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 SecuritiesOn October 29, 2018, the Company acquired Elixiter. The consideration paid in this transaction included 64,846 shares of Company common stockissued at closing with an aggregate value of approximately $1.7 million based on the average closing sales prices for the 30 consecutive trading days endingon the date immediately before the acquisition’s closing date. We relied on Section 4(a)(2) of the Securities Act of 1933, as amended, as the basis forexemption from registration of this issuance. These shares were issued in a privately negotiated transaction and not pursuant to a public solicitation.Issuer Purchases of Equity SecuritiesPrior to 2018, the Company's Board of Directors authorized the repurchase of up to $135.0 million of Company common stock. On February 20,2018, the Board of Directors authorized the expansion of the stock repurchase program by authorizing the repurchase of up to an additional $25.0 million ofCompany common stock and extended the expiration date of the program from December 31, 2018 to December 31, 2019. On August 15, 2018, the Board ofDirectors authorized an additional $75.0 million, for a total repurchase program of $235.0 million. The program could be suspended or discontinued at anytime, based on market, economic, or business conditions. The timing and amount of repurchase transactions will be determined by management based on itsevaluation of market conditions, share price, and other factors.Since the program’s inception on August 11, 2008, we have repurchased approximately $199.4 million (14.7 million shares) of our outstandingcommon stock through December 31, 2018.PeriodTotal Numberof SharesPurchased Average PricePaid Per Share (1) Total Number ofShares Purchased as Partof Publicly AnnouncedPlans or Programs Approximate DollarValueof Shares thatMay Yet Be PurchasedUnder the Plans orProgramsBeginning balance as of October 1, 201814,193,919 $13.16 14,193,919 $48,208,814October 1-31, 2018268,572 26.06 268,572 $41,208,824November 1-30, 2018200,000 25.10 200,000 $36,188,726December 1-31, 201825,000 24.46 25,000 $35,577,309Ending balance as of December 31, 201814,687,491 $13.58 14,687,491 (1)Average price paid per share includes commission.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, 2018, has been preparedin accordance with U.S. generally accepted accounting principles.

The most significant impact upon adoption was to third-party software and hardwarerevenue, which was primarily recorded on a gross basis as the principal in the transaction through December 31, 2017 and presented on a net basis as theagent beginning on January 1, 2018. Since the change in presentation was applied prospectively and prior period results were not restated, the adoption ofthe new standard resulted in significantly lower software and hardware revenues and costs for the year ended December 31, 2018 as compared to the yearsended December 31, 2017 and 2016. The impact of adopting ASC Topic 606 to services revenues and costs was immaterial.Services RevenuesServices revenues are derived from professional services that include developing, implementing, integrating, automating and extending businessprocesses, technology infrastructure, and software applications. Professional services revenues are recognized over time as services are rendered. Most of ourprojects are performed on a time and materials basis, while a portion of our revenues is derived from projects performed on a fixed fee or fixed fee percentcomplete basis. For time and material projects, revenues are recognized and billed by multiplying the number of hours our professionals expend in theperformance of the project by the hourly rates. For fixed fee contracts, revenues are recognized and billed by multiplying the established fixed rate per timeperiod by the number of time periods elapsed. For fixed fee percent complete projects, revenues are generally recognized using an input method based on theratio of hours expended to total estimated hours. Fixed fee percent complete engagements represented approximately 8% of our services revenues for the yearended December 31, 2018 compared to 8% and 11% for the years ended December 31, 2017 and 2016, respectively. On most projects, we are reimbursed forout-of-pocket expenses including travel and other project-related expenses. These reimbursements are included as a component of the transaction price of therespective professional services contract. The aggregate amount of reimbursed expenses will fluctuate depending on the location of our clients, the totalnumber of our projects that require travel, and whether our arrangements with our clients provide for the reimbursement of such expenses. In conjunction withservices provided, we occasionally receive referral fees under partner programs. These referral fees are recognized at a point in time when earned and recordedwithin services revenues.Software and Hardware RevenuesSoftware and hardware revenues are derived from sales of third-party software and hardware resales, in which we are considered the agent, and salesof internally developed software, in which we are considered the principal. Revenues from sales of third-party software and hardware are recorded on a netbasis, while revenues from internally developed software sales are recorded on a gross basis. Software and hardware revenues are expected to fluctuatedepending on our clients’ demand for these products. 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 costs of services and software and hardware costs. Costs of services consists primarily of cash and non-cashcompensation and benefits (including bonuses and non-cash compensation related to equity awards), costs associated with subcontractors, reimbursableexpenses and other 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 information21technology related equipment. Upon adoption of ASC Topic 606 on January 1, 2018, sales of third-party software and hardware were presented on a net basis,and as such, third-party software and hardware costs are no longer presented within cost of revenue in the current year.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.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.United States Tax ReformThe Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”) was signed into law on December 22, 2017. The law included significant changes to theU.S. corporate income tax system, including a federal corporate tax rate reduction from 35% to 21%, limitations on the deductibility of interest expense andexecutive compensation, and the transition of U.S. international taxation from a worldwide tax system to a territorial tax system. This change may result in aU.S. tax liability on those earnings which have not previously been repatriated to the U.S., with future foreign earnings potentially not subject to U.S. incometaxes when repatriated. The majority of the provisions had an impact on the Company beginning in fiscal year 2018. However, there were 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. See Note 13, Income Taxes, in the Notes to Consolidated Financial Statements for further information regardingthe impact of the 2017 Tax Act.The SEC 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. During the third quarter of 2018, the Company finalized and filed its 2017 income tax return. There were no materialchanges to the original estimate, and the one-year measurement period is now closed.Lease Accounting Standard Adopted January 1, 2019In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2016-02, Leases, which supersedes ASC Topic 840,Leases, and creates a new topic, ASC Topic 842, Leases. During the year end December 31, 2018, the FASB issued ASU No. 2018-10, CodificationImprovements to Topic 842, Leases, ASU No. 2018-11, Leases – Targeted Improvement, and ASU No. 2018-20, Leases (Topic 842): Narrow ScopeImprovements for Lessors which further amended ASU22No. 2016-02. These updates require lessees to recognize lease liabilities and right of use (“ROU”) assets for all leases, including operating leases, with a termgreater than 12 months on its balance sheet. The Company adopted the standard on January 1, 2019 using the modified retrospective method, and will befully presented in the Company’s Quarterly Report on Form 10-Q for the three months ended March 31, 2019. On January 1, 2019, the Company recognizedROU assets of approximately $22 million and lease liabilities of approximately $23 million related to its existing operating leases on the date of adoption.The difference between the ROU assets and lease liabilities primarily represents the existing deferred rent liabilities balance, resulting from historical straight-lining of operating leases, which was effectively reclassified upon adoption to reduce the measurement of the ROU assets. As the Company adopted ASU No.2016-02 using the modified retrospective method, the recognition of the ROU assets and lease liabilities will not impact the comparative period consolidatedbalance sheet. The impact from the adoption of ASU No. 2016-02 on the Company's consolidated statement of operations was immaterial. The adoption ofASU No. 2016-02 and its amendments will also result in additional disclosures around weighted average remaining lease terms, weighted average discountrates, variable lease payments and significant judgments and practical expedients used by the Company. Current minimum commitments undernoncancellable operating leases are disclosed in Note 16, Commitments and Contingencies, in the Notes to Consolidated Financial Statements.Results of OperationsThe following table summarizes our results of operations as a percentage of total revenues:Revenues:2018 2017 2016Services99.1% 92.0 % 89.7 %Software and hardware0.9 8.0 10.3Total revenues100.0 100.0 100.0Cost of revenues (exclusive of depreciation and amortization, shown separately below): Cost of services64.2 59.8 60.0Software and hardware costs— 6.9 8.9Total cost of revenues64.2 66.7 68.9Selling, general and administrative23.8 22.3 20.8Depreciation and amortization4.1 4.0 3.7Acquisition costs0.4 0.3 0.3Adjustment to fair value of contingent consideration0.3 0.7 (0.3)Income from operations7.2 6.0 6.6Net interest expense0.7 0.4 0.3Net other expense— — —Income before income taxes6.5 5.6 6.3Provision for income taxes1.6 1.8 2.1Net income4.9% 3.8 % 4.2 %Year Ended December 31, 2018 Compared to Year Ended December 31, 2017Revenues.

The increase in services revenues was due to acquisitions as well as an increase in our base business. Services revenues attributable to our base businessincreased $12.5 million while services revenues attributable to acquired companies was $34.9 million, resulting in a total increase of $47.4 million.Software and hardware revenues decreased 89% to $4.4 million for the year ended December 31, 2018 from $38.6 million for the year endedDecember 31, 2017 as a result of the net presentation of third-party software and hardware sales upon adoption of ASC Topic 606.Cost of Revenues (exclusive of depreciation and amortization, discussed separately below). Total cost of revenues decreased 1% to $319.8 millionfor the year ended December 31, 2018 from $323.7 million for the year ended December 31, 2017. Cost of services increased 10% to $319.8 million for theyear ended December 31, 2018 from $290.5 million for the year ended December 31, 2017 primarily due to higher headcount in response to higher servicesrevenues and acquisitions. Services costs as a percentage of services revenues decreased to 64.7% for the year ended December 31, 2018 from 65.0% for theyear ended December 31, 2017 primarily driven by an increase in utilization. The average bill rate for our professionals decreased to $124 per hour for theyear ended December 31, 2018 from $126 per hour for the year ended December 31, 2017.Selling, General and Administrative. SG&A expenses increased 10% to $118.5 million for the year ended December 31, 2018 from $108.2 millionfor the year ended December 31, 2017 primarily due to acquisitions completed during 2018, increased variable compensation expense related to bonus costsand the fluctuations in expenses as detailed in the following table. SG&A expenses, as a percentage of services revenues, decreased to 24.0% for the yearended December 31, 2018 from 24.2% for the year ended December 31, 2017.Selling, General and Administrative Expense(in millions)For the Year EndedDecember 31, 2018 For the Year EndedDecember 31, 2017 Increase(Decrease) PercentageChangeSalary expense$45.2 $43.7 $1.5 3 %Sales-related costs11.0 10.5 0.5 5 %Office costs10.3 9.4 0.9 10 %Stock compensation expense10.2 9.3 0.9 10 %Variable compensation expense9.3 5.2 4.1 79 %Travel & entertainment6.2 5.4 0.8 15 %Benefits expense6.1 6.5 (0.4) (6)%IT/Infrastructure5.2 5.2 — — %Bad debt expense0.4 0.9 (0.5) (56)%Other14.6 12.1 2.5 21 %Total$118.5 $108.2 $10.3 10 %Depreciation. Depreciation expense decreased 14% to $4.1 million for the year ended December 31, 2018 from $4.7 million for the year endedDecember 31, 2017. The decrease in depreciation expense is primarily attributable to certain property and equipment becoming fully depreciated. Depreciation expense as a percentage of total revenues was 0.8% for the year ended December 31, 2018 and 1.0% for the year ended December 31, 2017.24Amortization. Amortization expense increased 9% to $16.4 million for the year ended December 31, 2018 from $15.0 million for the year endedDecember 31, 2017. The increase in amortization expense was due to the addition of intangible assets from the 2018 and 2017 acquisitions, partially offsetby intangible assets from previous acquisitions becoming fully amortized. Amortization expense as a percentage of total revenues was 3.3% for the yearended December 31, 2018 and 3.1% for the year ended December 31, 2017.Acquisition Costs. Acquisition-related costs of $1.9 million were incurred during 2018 compared to $1.4 million during 2017. 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 adjustment of $1.8 million was recorded during the year ended December 31, 2018which represents the net impact of the fair market value adjustments to the Clarity Consulting, Inc. and Truth Labs, LLC (together, “Clarity”) and Southportrevenue and earnings-based contingent consideration liabilities based on favorable performance compared to the original estimates in addition to theaccretion of the fair value estimate for the revenue and earnings-based contingent consideration related to the acquisitions of Clarity, Southport, StoneTemple and Elixiter. An adjustment of $3.2 million was recorded during the year ended December 31, 2017 which represented the net impact of the fairmarket value adjustments to the Clarity, RAS Associates, LLC (“RAS”), and Bluetube, LLC (“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.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 24.1% for the year ended December 31, 2018 from 31.5% for the year ended December 31, 2017. Thedecrease in the effective rate is primarily due to the reduction of the federal corporate tax rate beginning in 2018 as a result of the 2017 Tax Act.Year Ended December 31, 2017 Compared to Year Ended December 31, 2016Revenues. Total revenues decreased less than 1% to $485.3 million for the year ended December 31, 2017 from $487.0 million for the year endedDecember 31, 2016.

Services revenues attributable to our base business decreased $24.5 million whileservices revenues attributable to acquired companies was $34.0 million, resulting in a total increase of $9.6 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.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. Cost of services decreased 1% to $290.5 million for the year ended December31, 2017 from $292.1 million for the year ended December 31, 2016. Services costs as a percentage of services revenues25decreased to 65.0% for the year ended December 31, 2017 from 66.8% for the year ended December 31, 2016 primarily driven by improvements in the NorthAmerican average bill rate and utilization, as well as a $1.0 million cost reduction related to labor incentives earned by the Company’s Louisiana and Chinaoperations. The average bill rate for our professionals decreased to $126 per hour for the year ended December 31, 2017 from $127 per hour for the yearended December 31, 2016 primarily due to the impact of a higher mix of lower bill rate offshore resources.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 services revenues, increased to 24.2% for the year ended December 31, 2017 from 23.2% for the yearended December 31, 2016.Selling, General and Administrative Expense(in millions)For the Year EndedDecember 31, 2017 For the Year EndedDecember 31, 2016 Increase(Decrease) PercentageChangeSalary expense$43.7 $41.8 $1.9 5 %Sales-related costs10.5 9.5 1.0 11 %Office costs9.4 9.0 0.4 4 %Stock compensation expense9.3 8.9 0.4 4 %Benefits expense6.5 5.4 1.1 20 %Travel & entertainment5.4 6.2 (0.8) (13)%IT/Infrastructure5.2 4.3 0.9 21 %Variable compensation expense5.2 2.0 3.2 160 %Bad debt expense0.9 1.1 (0.2) (18)%Other12.1 13.1 (1.0) (8)%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 fully depreciated. 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 2017 and 2016 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 Pup Group, Inc. d/b/a Enlighten (“Enlighten”) revenue and earnings-based contingent considerationliability partially offset by the accretion of the fair value estimate for the revenue and earnings-based contingent consideration related to the acquisition ofZeon Solutions Incorporated and certain related entities (collectively, “Zeon”), Market Street Solutions, Inc. (“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 tax26caused by passage of the 2017 Tax Act. These favorable items were partially offset by an increase in our unrecognized tax benefits.Liquidity and Capital ResourcesSelected measures of liquidity and capital resources are as follows (in millions): As of December 31, 2018 2017 2016Cash and cash equivalents (1)$45.0 $6.3 $10.1Working capital (including cash and cash equivalents) (2)$103.0 $67.9 $76.4Amounts available under credit facilities$124.8 $69.7 $93.0(1)The balance at December 31, 2018 includes $5.8 million held by our Canadian, Indian and United Kingdom subsidiaries which is not available tofund domestic operations unless deemed repatriated.

The primary components of operating cash flows for the year ended December 31, 2016 were net income of $20.5 million plus net non-cash charges of $35.1 million and reductions in net operating assets of $7.7 million, primarily driven by reductions in accounts receivable.Net Cash Used in Investing ActivitiesDuring the year ended December 31, 2018, we used $26.6 million for acquisitions and $4.7 million to purchase property and equipment and todevelop software. During the year ended December 31, 2017, we used $37.9 million for acquisitions and$4.3 million to purchase property and equipment andto develop software. During the year ended December 31, 2016, we used $7.5 million for acquisitions and $6.0 million to purchase property and equipmentand to develop software. During the year ended December 31, 2016, we also purchased and subsequently sold short-term investments of $0.9 million andsettled $2.8 million of Company-owned life insurance (“COLI”) policies, the proceeds of which were used to fund new COLI policies.Net Cash Provided By Financing ActivitiesFor the year ended December 31, 2018, we received $138.9 million of proceeds from the issuance of the Notes, net of issuance costs, received $12.1million of proceeds from the sale of the Notes Warrants and paid $20.7 million for the privately negotiated Notes Hedges. We drew down $161.0 million fromour line of credit, repaid $216.0 million on our line of credit, used $64.4 million to repurchase shares of our common stock through the stock repurchaseprogram, used $5.1 million to remit taxes withheld as part of a net share settlement of restricted stock vesting and we received proceeds from sales of stockthrough the Employee Stock Purchase Plan of $0.1 million. We also used $4.0 million to settle the contingent consideration for the purchase of Clarity.

We also used $2.2 million to settle the contingent consideration for the purchase of Zeon and paid $0.2 million in feesrelated to our credit facility.Availability of Funds from Credit Facility27On 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 provides for revolving credit borrowings up to a maximum principal amountof $125.0 million, subject to a commitment increase of $75.0 million. All outstanding amounts owed under the Credit Agreement become due and payableno 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, 2018, the Company had one outstanding letter of credit for$0.2 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 (5.50% on December 31, 2018) plus a marginranging from 0.00% to 0.50% or one-month LIBOR (2.50% on December 31, 2018) 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, 2018, the Company had $124.8 million of unused borrowing capacity.At December 31, 2018, we were in compliance with all covenants under the Credit Agreement.Stock Repurchase ProgramPrior to 2018, the Company's Board of Directors authorized the repurchase of up to $135.0 million of Company common stock. On February 20,2018, the Board of Directors authorized the expansion of the stock repurchase program by authorizing the repurchase of up to an additional $25.0 million ofCompany common stock and extended the expiration date of the program from December 31, 2018 to December 31, 2019. On August 15, 2018, the Board ofDirectors authorized an additional $75.0 million, for a total repurchase program of $235.0 million. The program could be suspended or discontinued at anytime, based on market, economic, or business conditions. The timing and amount of repurchase transactions will be determined by management based on itsevaluation of market conditions, share price, and other factors. Since the program’s inception on August 11, 2008, the Company has repurchasedapproximately $199.4 million (14.7 million shares) of outstanding common stock through December 31, 2018.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. Contractual ObligationsFor the year ended December 31, 2018, there were no material changes outside the ordinary course of business in lease obligations or othercontractual obligations. See Note 16, Commitments and Contingencies, in the Notes to Consolidated Financial Statements for further description of ourcontractual obligations.As of December 31, 2018, there was no balance outstanding under the Credit Agreement as compared to $55.0 million as of December 31,2017. Balances outstanding under the Credit Agreement are classified as “Long-term debt” within the Consolidated Balance Sheet and will become due andpayable no later than the final maturity date of June 9, 2022. Additionally, there were $120.1 million of outstanding Notes, net of unamortized debt discountand issuance costs, as of December 31, 2018 compared to zero as of December 31, 2017. The amount is classified as “Long-term debt” within theConsolidated Balance Sheets as of December 31, 2018 and will become due and payable no later than the final maturity date of September 15, 2023.We have incurred commitments to make future payments under contracts such as leases, the Credit Agreement and the Notes, as well asnoncancellable purchase obligations, which primarily relate to multi-year third-party software sales. Maturities under these contracts are set forth in thefollowing table as of December 31, 2018 (in thousands):28 Payments Due by PeriodContractual ObligationsTotal Less Than1 Year 1-3Years 3-5Years More Than5 YearsOperating lease obligations$26,120 $7,375 $11,848 $5,477 $1,420Total debt120,067 — — 120,067 —Purchase obligations5,530 2,123 2,355 1,052 —Total$151,717 $9,498 $14,203 $126,596 $1,420ConclusionIf 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, 2018 of $45.0 million, approximately $5.8million 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, as well as the proceeds from the Notes issuance in the third quarter of 2018. Therefore, the Company has no current plans to repatriate cash from theseforeign subsidiaries in the foreseeable future. As of December 31, 2018, the aggregate unremitted earnings of the Company’s foreign subsidiaries for which adeferred income tax liability has not been recorded was approximately $8.5 million, and the unrecognized deferred tax liability on unremitted earnings wasapproximately $0.5 million. As of December 31, 2018, $1.3 million of the total cash and cash equivalents was held by the Company's Chinese subsidiary.During the year ended December 31, 2017, the Company determined that the Chinese subsidiary's earnings were no longer permanently reinvested and mayrepatriate available earnings from time to time.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,convertible debt, and income taxes.Revenue Recognition and Allowance for Doubtful AccountsPrior to January 1, 2018, the Company recognized revenue under ASC Subtopic 985-605, Software - Revenue Recognition, ASC Subtopic 605-25,Revenue Recognition - Multiple-Element Arrangements, and ASC Section 605-10-S99 (Staff Accounting Bulletin Topic 13, Revenue Recognition). OnJanuary 1, 2018, the Company adopted ASC Topic 606, which replaced most existing revenue recognition guidance. The most significant impact uponadoption was to third-party software and hardware revenue, which was primarily recorded on a gross basis as the principal in the transaction throughDecember 31, 2017 and presented on a net basis as the agent as of January 1, 2018. Refer to Note 2, Summary of Significant Accounting Policies, in the Notesto Consolidated Financial Statements for additional information on the impact of adoption.The following discussion relates to the Company’s revenue recognition policy, effective January 1, 2018, under ASC Topic 606.The Company’s revenues consist of services and software and hardware sales. In accordance with ASC Topic 606, revenues are recognized whencontrol of these services or goods are transferred to clients, in an amount that reflects the consideration the Company expects to be entitled to in exchange forthose services or goods.Services revenues are primarily comprised of professional services that include developing, implementing, automating and extending businessprocesses, technology infrastructure, and software applications. The Company’s professional services span29multiple industries, platforms and solutions; however, the Company has remained relatively diversified and does not believe that it has significant revenueconcentration within any single industry, platform or solution.Professional services revenues are recognized over time as services are rendered. Most projects are performed on a time and materials basis, while aportion of revenues is derived from projects performed on a fixed fee or fixed fee percent complete basis. For time and material contracts, revenues aregenerally recognized and invoiced by multiplying the number of hours expended in the performance of the contract by the hourly rates. For fixed feecontracts, revenues are generally recognized and invoiced by multiplying the fixed rate per time period established in the contract by the number of timeperiods elapsed. For fixed fee percent complete contracts, revenues are generally recognized using an input method based on the ratio of hours expended tototal estimated hours, and the client is invoiced according to the agreed-upon schedule detailing the amount and timing of payments in the contract. Clientsare typically 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 thetime is worked and approved at the end of a fiscal period and the invoice has not yet been sent to the client, the amount is recorded as revenue once theCompany verifies all other revenue recognition criteria have been met, and the amount is classified as a receivable as the right to consideration isunconditional at that point. Amounts invoiced and collected in excess of revenues recognized are contract liabilities, which are classified as deferredrevenues in the Consolidated Balance Sheet. The term between invoicing and payment due date is not significant. Contracts for professional services providefor 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. Certain contracts may includevolume discounts or holdbacks, which are accounted for as variable consideration, but are not typically significant. The Company estimates variableconsideration based on historical experience and forecasted sales and includes the variable consideration in the transaction price.Other services revenues are comprised of hosting fees, partner referral fees, maintenance agreements, training and internally developed software-as-a-service (“SaaS”) sales. Revenues from hosting fees, maintenance agreements, training and internally developed SaaS sales are generally recognized over timeusing a time-based measure of progress as services are rendered. Partner referral fees are recorded at a point in time upon meeting specified requirements set byeach partner to earn the respective fee.On many professional service projects, the Company is also reimbursed for out-of-pocket expenses including travel and other project-relatedexpenses. These reimbursements are included as a component of the transaction price of the respective professional services contract and are invoiced as theexpenses are incurred. The Company structures its professional services arrangements to recover the cost of reimbursable expenses without a markup.Software and hardware revenues are comprised of third-party software and hardware resales, in which the Company is considered the agent, and salesof internally developed software, in which the Company is considered the principal. Third-party software and hardware revenues are recognized and invoicedwhen the Company fulfills its obligation to arrange the sale, which occurs when the purchase order with the vendor is executed and the customer has accessto the software or the hardware has been shipped to the customer. Internally developed software revenues are recognized and invoiced when control istransferred to the customer, which occurs when the software has been made available to the customer and the license term has commenced. Revenues fromthird-party software and hardware sales are recorded on a net basis, while revenues from internally developed software sales are recorded on a gross basis.There are no significant cancellation or termination-type provisions for the Company’s software and hardware sales, and the term between invoicing andpayment due date is not significant.Arrangements with clients may contain multiple promises such as delivery of software, hardware, professional services or post-contract supportservices. These promises are accounted for as separate performance obligations if they are distinct. For arrangements with clients that contain multipleperformance obligations, the transaction price is allocated to the separate performance obligations based on estimated relative standalone selling price, whichis estimated by the expected cost plus a margin approach, taking into consideration market conditions and competitive factors. Since the duration ofcontracts that contain multiple performance obligations is typically short given contract cancellation provisions, the allocation of the transaction price to theseparate performance obligations is not considered a significant estimate.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 judgment30is used in assessing the ultimate realization of these receivables, including reviewing the financial stability of the client, evaluating the successful mitigationof service delivery disputes, and gauging current market conditions. If the evaluation of service delivery issues or a client’s ability to pay is incorrect, futurereductions to revenue or bad debt expense may be incurred.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 initial 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 initialcontingent consideration is then valued using a Monte Carlo simulation. The Company finalizes the purchase price allocation once certain initial accountingvaluation estimates are finalized, and no later than 12 months following the acquisition date.Convertible DebtIn accordance with accounting for debt with conversion and other options, the Company bifurcated the principal amount of the Notes issued onSeptember 11, 2018 into liability and equity components. The initial liability component of the Notes was valued based on the contractual cash flowsdiscounted at an appropriate comparable market non-convertible debt borrowing rate at the date of issuance of 5.7%. The equity component representing theconversion option and calculated as the residual amount of the proceeds was recorded as an increase in additional paid-in capital within stockholders’ equity,partially offset by the associated deferred tax effect. The amount recorded within additional paid-in capital is not to be remeasured as long as it continues tomeet the conditions for equity classification. The resulting debt discount is being amortized to interest expense using the effective interest method over theperiod from the issuance date through the contractual maturity date of September 15, 2023. The Company utilizes the treasury stock method to calculate theeffects of the Notes on diluted earnings per share.In connection with the issuance of the Notes, the Company entered into Notes Hedges with the Option Counterparties. The Notes Hedges providethe Company with the option to acquire, on a net settlement basis, shares of common stock equal to the number of shares of common stock that notionallyunderlie the Notes and corresponds to the conversion price of the Notes. If the Company elects cash settlement and exercises the Notes Hedges, the aggregateamount of cash received from the Option Counterparties will cover the aggregate amount of cash that the Company would be required to pay to the holders ofthe Notes, less the principal amount thereof. The Notes Hedges do not meet the criteria for separate accounting as a derivative as they are indexed to theCompany’s stock and are accounted for as freestanding financial instruments. The Notes Hedges were recorded as a reduction in additional paid-in capitalwithin stockholders’ equity, partially offset by the associated deferred tax effect.Additionally, in connection with the issuance of the Notes, the Company sold the Notes Warrants in privately negotiated transactions with theOption Counterparties. The strike price of the Notes Warrants is subject to certain adjustments under the terms of the Notes Warrants. As a result of the NotesWarrants and related transactions, the Company is required to recognize incremental dilution of earnings per share to the extent the average share price isover the strike price of the Notes Warrants for any fiscal quarter. The Notes Warrants may be settled in net shares of common stock or net cash at theCompany’s election. The Notes Warrants were recorded as an increase in additional paid-in capital within stockholders’ equity.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 13, Income Taxes, in the Notes toConsolidated Financial Statements for additional information regarding the 2017 Tax Act.31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 16, 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, 2018, we were exposed to changes in exchange rates between the U.S.dollar and the Canadian dollar, Indian rupee, Chinese yuan, 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 14, Derivatives, in the Notes toConsolidated Financial Statements for further discussion.Interest Rate SensitivityAs of December 31, 2018, there was no outstanding balance and $124.8 million of available borrowing capacity under our credit facility. To theextent we have outstanding borrowings under the credit facility, our interest expense will fluctuate as the interest rate for the line of credit floats based, at ouroption, on the prime rate plus a margin or the one-month LIBOR rate plus a margin.During the third quarter of 2018, we issued Notes which have a fixed interest rate of 2.375%. The fair value of the Notes may increase or decrease forvarious reasons, including fluctuations in the market price of our common stock, fluctuations in market interest rates and fluctuations in general economicconditions. Based upon the quoted market price as of December 31, 2018, the aggregate fair value of the Notes was approximately $128.3 million.We had unrestricted cash and cash equivalents totaling $45.0 million at December 31, 2018 and $6.3 million at December 31, 2017. Theunrestricted cash and cash equivalents are primarily held for working capital purposes and acquisitions. We do not enter into investments for trading orspeculative purposes.32Item 8.Financial Statements and Supplementary Data.PERFICIENT, INC.CONSOLIDATED BALANCE SHEETS December 31, 2018 2017ASSETS(In

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.Certain prior period financial statement amounts have been reclassified to conform to current period presentation. This reclassification relates toreimbursable expenses, which have been combined with services revenues and cost of services within revenues and cost of revenues in the ConsolidatedStatements of Operations.2. Summary of Significant Accounting PoliciesUse of EstimatesThe preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management tomake estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of thefinancial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates, andsuch differences could be material to the financial statements.Revenue RecognitionAs of January 1, 2018, the Company recognizes revenues in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue fromContracts with Customers. See Note 3, Revenues, for information regarding the Company’s revenue recognition accounting policies.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 CompensationStock-based compensation is accounted for in accordance with ASC Topic 718, Compensation – Stock Compensation. Under this guidance, theCompany recognizes share-based compensation ratably using the straight-line attribution method over the requisite service period, which is generally threeyears. In addition, the Company has elected to estimate the amount of expected forfeitures when calculating share-based compensation, instead of accountingfor forfeitures as they occur. The fair value of restricted stock awards is based on the value of the Company’s common stock on the date of the grant.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,40classification, treatment of interest and penalties, and disclosure of such positions. On December 22, 2017, the U.S. government enacted the Tax Cuts andJobs Act of 2017 (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 13, Income Taxes, for additional information regarding the 2017Tax 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. The Company has one reporting unit forpurposes of the goodwill impairment review. ASC Topic 350 permits an assessment of qualitative factors to determine whether it is more likely than not thatthe fair value is less than the carrying amount of the Company before applying the quantitative goodwill impairment test. If it is more likely than not that thefair value is less than the carrying amount of the Company, the quantitative goodwill impairment test will be conducted to detect and measure anyimpairment. Based upon the Company’ s qualitative assessment, it is more likely than not that the fair value of the Company is greater than its carryingamount. No impairment charges were recorded for 2018, 2017 or 2016.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 2018, 2017 or 2016.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 initial 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 initial contingent consideration is measured. Based upon these assumptions, thecontingent consideration is then valued using a Monte Carlo simulation. The Company finalizes the purchase price allocation once certain initial accountingvaluation estimates are finalized, and no later than 12 months following the acquisition date.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 related to its 2.375% Convertible Senior Notes Due 2023 (the “Notes”) arecarried at their principal amount less unamortized debt discount41and issuance costs, and are not carried at fair value at each period end. See Note 12, Long-Term Debt, for information regarding the Company’s convertibledebt accounting policies.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 14, Derivatives, foradditional information regarding our derivative financial instruments.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. Approximately 98% of our revenues were derived from clients in the United Statesduring each of the years ended December 31, 2018, 2017 or 2016. 1% and 2% of the Company’s non-current assets were located outside the United States forthe years ended December 31, 2018 and 2017, respectively.Recent Accounting PronouncementsIn May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue fromContracts with Customers (ASC Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer ofpromised goods or services to customers. ASU No. 2014-09 replaced most existing revenue recognition guidance in U.S. GAAP. In 2015, the FASB deferredthe 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-Scope Improvements and Practical Expedients and ASU No. 2016-20,Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, all of which further amended ASU No. 2014-09. TheCompany adopted the standard on January 1, 2018 using the modified retrospective method which requires a cumulative-effect adjustment to the openingbalance of retained earnings within stockholders’ equity. The Company has determined that the most significant impact upon adoption was to third-partysoftware and hardware revenue, which was primarily recorded on a gross basis as the principal in the transaction through December 31, 2017 and presented ona net basis as the agent as of January 1, 2018. The adoption of the standard also resulted in minor changes to the timing of revenue recognition. As the agent,revenue from multi-year sales of third-party software and support is recognized upfront as the performance obligation is fulfilled, rather than annually asinvoiced to the customer. Additionally, variable consideration related to service contracts, such as volume discounts and holdbacks, are recognized earlierunder the new standard in certain instances. The impact from these timing changes was immaterial as of January 1, 2018, and therefore, did not result in acumulative-effect adjustment to the opening balance of retained earnings. The adoption of the standard also resulted in increases to accounts receivable, netand deferred revenue within other current liabilities for those contracts under which the Company’s right to consideration is unconditional. Additionally, theupfront revenue recognition of multi-year sales of third-party software and support resulted in increases to accounts receivable, net and other non-currentassets for the portion of the consideration that had not yet been billed to the client and increases to accounts payable and non-current liabilities for amountsnot yet due to the third-party software vendor. Refer to Impacts of ASC Topic 606 Adoption on Current Period Results below for the impact of adopting ASCTopic 606 on the Consolidated Balance Sheet as of December 31, 2018 and the Consolidated Statement of Operations for the year ended December 31, 2018.There was no material impact on the Consolidated Statement of Cash Flows for the year ended December 31, 2018. The adoption of ASU No. 2014-09 and itsamendments also resulted in additional disclosures around the nature and timing of performance obligations, contract costs, and deferred revenue, as well assignificant judgments and practical expedients used by the Company.

During the year end December 31, 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, ASU 2018-11, Leases –Targeted Improvement, and ASU 2018-20, Leases (Topic 842): Narrow Scope Improvements for Lessors which further amended ASU No. 2016-02. Theseupdates require lessees to recognize lease liabilities and right of use (“ROU”) assets for all leases, including operating leases, with a term greater than 12months on its balance sheet. The Company adopted the standard on January 1, 2019 using the modified retrospective method, and will be fully presented inthe Company’s Quarterly Report on Form 10-Q for the three months ended March 31, 2019. On January 1, 2019, the Company recognized ROU assets ofapproximately $22 million and lease liabilities of approximately $23 million related to their existing operating leases on the date of adoption. Thedifference between the ROU assets and lease liabilities primarily represents the existing deferred rent liabilities balance, resulting from historical straight-lining of operating leases, which was effectively reclassified upon adoption to reduce the measurement of the ROU assets. As the Company adopted ASU No.2016-02 using the modified retrospective method, the recognition of the ROU assets and lease liabilities will not impact the comparative period consolidatedbalance sheet. The impact from the adoption of ASU No. 2016-02 on the Company’s consolidated statement of operations was immaterial. The adoption ofASU No. 2016-02 and its amendments will also result in additional disclosures around weighted average remaining lease terms, weighted average discountrates, variable lease payments and significant judgments and practical expedients used by the Company. Current minimum commitments undernoncancellable operating leases are disclosed in Note 16, Commitments and Contingencies.433. RevenuesPrior to January 1, 2018, the Company recognized revenue under ASC Subtopic 985-605, Software - Revenue Recognition, ASC Subtopic 605-25,Revenue Recognition - Multiple-Element Arrangements, and ASC Section 605-10-S99 (Staff Accounting Bulletin Topic 13, Revenue Recognition). OnJanuary 1, 2018, the Company adopted ASC Topic 606, which replaced most existing revenue recognition guidance. The most significant impact uponadoption was to third-party software and hardware revenue, which was primarily recorded on a gross basis as the principal in the transaction throughDecember 31, 2017 and presented on a net basis as the agent as of January 1, 2018. Refer to Note 2, Summary of Significant Accounting Policies, foradditional information on the impact of adoption.The following discussion relates to the Company’s revenue recognition policy, effective January 1, 2018, under ASC Topic 606.The Company’s revenues consist of services and software and hardware sales and is recognized in accordance with ASC Topic 606. Under thisguidance, revenues are recognized when control of these services or goods are transferred to clients, in an amount that reflects the consideration the Companyexpects to be entitled to in exchange for those services or goods.Service RevenuesServices revenues are primarily comprised of professional services that include developing, implementing, automating and extending businessprocesses, technology infrastructure, and software applications. The Company’s professional services span multiple industries, platforms and solutions;however, the Company has remained relatively diversified and does not believe that it has significant revenue concentration within any single industry,platform or solution.Professional services revenues are recognized over time as services are rendered. Most projects are performed on a time and materials basis, while aportion of revenues is derived from projects performed on a fixed fee or fixed fee percent complete basis. For time and material contracts, revenues aregenerally recognized and invoiced by multiplying the number of hours expended in the performance of the contract by the hourly rates. For fixed feecontracts, revenues are generally recognized and invoiced by multiplying the fixed rate per time period established in the contract by the number of timeperiods elapsed. For fixed fee percent complete contracts, revenues are generally recognized using an input method based on the ratio of hours expended tototal estimated hours, and the client is invoiced according to the agreed-upon schedule detailing the amount and timing of payments in the contract.Clients are typically billed monthly for services provided during that month, but can be billed on a more or less frequent basis as determined by thecontract. If the time is worked and approved at the end of a fiscal period and the invoice has not yet been sent to the client, the amount is recorded as revenueonce the Company verifies all other revenue recognition criteria have been met, and the amount is classified as a receivable as the right to consideration isunconditional at that point. Amounts invoiced and collected in excess of revenues recognized are contract liabilities, which are classified as deferredrevenues in the Consolidated Balance Sheet. The term between invoicing and payment due date is not significant. Contracts for professional services providefor 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. Certain contracts may includevolume discounts or holdbacks, which are accounted for as variable consideration, but are not typically significant. The Company estimates variableconsideration based on historical experience and forecasted sales and includes the variable consideration in the transaction price.Other services revenues are comprised of hosting fees, partner referral fees, maintenance agreements, training and internally developed software-as-a-service (“SaaS”) sales. Revenues from hosting fees, maintenance agreements, training and internally developed SaaS sales are generally recognized over timeusing a time-based measure of progress as services are rendered. Partner referral fees are recorded at a point in time upon meeting specified requirements set byeach partner to earn the respective fee.On many professional service projects, the Company is also reimbursed for out-of-pocket expenses including travel and other project-relatedexpenses. These reimbursements are included as a component of the transaction price of the respective professional services contract and are invoiced as theexpenses are incurred. The Company structures its professional services arrangements to recover the cost of reimbursable expenses without a markup.Software and Hardware Revenues44Software and hardware revenues are comprised of third-party software and hardware resales, in which the Company is considered the agent, and salesof internally developed software, in which the Company is considered the principal. Third-party software and hardware revenues are recognized and invoicedwhen the Company fulfills its obligation to arrange the sale, which occurs when the purchase order with the vendor is executed and the customer has accessto the software or the hardware has been shipped to the customer. Internally developed software revenues are recognized and invoiced when control istransferred to the customer, which occurs when the software has been made available to the customer and the license term has commenced. Revenues fromthird-party software and hardware sales are recorded on a net basis, while revenues from internally developed software sales are recorded on a gross basis.There are no significant cancellation or termination-type provisions for the Company’s software and hardware sales, and the term between invoicing andpayment due date is not significant.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.Arrangements with Multiple Performance ObligationsArrangements with clients may contain multiple promises such as delivery of software, hardware, professional services or post-contract supportservices. These promises are accounted for as separate performance obligations if they are distinct. For arrangements with clients that contain multipleperformance obligations, the transaction price is allocated to the separate performance obligations based on estimated relative standalone selling price, whichis estimated by the expected cost plus a margin approach, taking into consideration market conditions and competitive factors. Since the duration ofcontracts that contain multiple performance obligations is typically short given contract cancellation provisions, the allocation of the transaction price to theseparate performance obligations is not considered a significant estimate.Contract CostsIn accordance with the terms of the Company’s sales commission plan, commissions are not earned until the related revenue is recognized.Therefore, sales commissions are expensed as they are earned. Certain sales incentives are accrued based on achievement of specified bookings goals. Forthese incentives, the Company applies the practical expedient that allows the Company to expense the incentives as incurred, since the amortization periodwould have been one year or less.Deferred RevenueThe Company’s deferred revenue balance as of December 31, 2017 was $3.3 million, which increased to $6.1 million as of January 1, 2018 due tothe adoption of ASC Topic 606. Substantially all of the December 31, 2017 deferred revenue balance was recognized in revenue during the year endedDecember 31, 2018. The deferred revenue balance as of December 31, 2018 was $8.1 million. Deferred revenue balances assumed in the Company’sacquisitions during the year ended December 31, 2018 were $0.8 million.Transaction Price Allocated to Remaining Performance Obligations Due to the ability of the client or the Company to cancel or terminate the contract within a given period of time (generally 10 to 30 days’ notice isrequired), the majority of the Company’s contracts have a term of less than one year. Perficient does not disclose the value of unsatisfied performanceobligations for contracts with an original maturity date of one year or less or time and materials contracts for which the Company has the right to invoice forservices performed. Revenue related to unsatisfied performance obligations for remaining contracts as of December 31, 2018 was immaterial. 45Disaggregation of RevenueThe following table presents revenue disaggregated by revenue source and pattern of revenue recognition (in thousands): Year Ended December 31, 2018 Over Time Point In Time Total RevenuesTime and materials contracts$339,708 $— $339,708Fixed fee percent complete contracts38,234 — 38,234Fixed fee contracts84,374 — 84,374Reimbursable expenses13,348 — 13,348Total professional services fees475,664 — 475,664Other services revenue*14,814 3,523 18,337Total services490,478 3,523 494,001Software and hardware— 4,374 4,374Total revenues$490,478 $7,897 $498,375* Other services revenue primarily consists of hosting fees, maintenance, training, internally developed SaaS and partner referral fees.The following table presents revenue disaggregated by geographic area, as determined by the billing address of customers (in thousands): Year Ended December 31,2018United States$487,849Canada3,481Other countries7,045Total revenues$498,3754. 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 2018, 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 for the years ended December 31, 2018 and 2017, and approximately 6% of totalrevenues for the year ended December 31, 2016.5. Stock-Based CompensationStock PlansThe Company’s Second Amended and Restated Perficient, Inc. 2012 Long Term Incentive Plan (as amended, the “Incentive Plan”) allows for thegranting of various types of stock awards to eligible individuals. The Compensation Committee of the Board of Directors administers the Incentive Plan anddetermines the terms of all stock awards made under the Incentive Plan. The Company may issue stock awards of up to 7.0 million shares of Common Stockpursuant to the Incentive Plan. As of December 31, 2018, there were 2.6 million shares of Common Stock available for issuance under the Incentive Plan.Restricted stock activity for the year ended December 31, 2018 was as follows (in thousands, except fair value information):46 Shares Weighted-AverageGrant DateFair ValueRestricted stock awards outstanding at December 31, 20171,436 $18.12Awards granted (1)747 $23.62Awards vested (2)(669) $18.17Awards forfeited(104) $17.68Restricted stock awards outstanding at December 31, 20181,410 $20.95 (1)The weighted average grant date fair value of shares granted during 2017 and 2016 was $18.68 and $16.79, respectively.(2)The total fair value of restricted shares vested during the years ended December 31, 2018, 2017 and 2016 was $15.8 million, $12.0 million and $10.8million, respectively. The Company recognized $16.4 million, $14.7 million and $14.2 million of share-based compensation expense during 2018, 2017 and 2016,respectively, which included $2.7 million, $2.5 million and $2.4 million of expense for retirement savings plan contributions, respectively. The associatedcurrent and future income tax benefit recognized during 2018, 2017 and 2016 was $3.3 million, $4.6 million and $4.3 million, respectively. As of December31, 2018, there was $22.2 million of total unrecognized compensation cost, net of estimated forfeitures, related to non-vested share-based awards. This cost isexpected to be recognized over a weighted-average period of two years. Generally restricted stock awards vest over a three year service period.Employee Stock Purchase PlanThe Employee Stock Purchase Plan (the “ESPP”) is a broadly-based stock purchase plan in which any eligible employee may elect to participate byauthorizing the Company to make payroll deductions in a specific amount or designated percentage to pay the exercise price of an option. In no event willthe ESPP permit an employee to purchase common stock with a fair market value in excess of $25,000 in any calendar year and the Compensation Committeeof the Company has set the current annual participation limit at $12,500. During the year ended December 31, 2018, approximately 7,473 shares werepurchased under the ESPP.There are four three-month offering periods in each calendar year beginning on January 1, April 1, July 1, and October 1, respectively. The purchaseprice of shares offered under the ESPP is an amount equal to 95% of the fair market value of the common stock on the date of purchase (occurring on,respectively, March 31, June 30, September 30, and December 31). The ESPP is designed to comply with Section 423 of the Internal Revenue Code of 1986,as amended (the “Code”), and thus is eligible for the favorable tax treatment afforded by Section 423.6. 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):47 Year Ended December 31, 2018 2017 2016Net income$24,559 $18,581 $20,459Basic: Weighted-average shares of common stock outstanding32,415 33,016 34,023Shares used in computing basic net income per share32,415 33,016 34,023 Effect of dilutive securities: Restricted stock subject to vesting672 488 493Contingently issuable shares (1)— — 2Shares issuable for acquisition consideration (2)415 562 483Shares used in computing diluted net income per share33,502 34,066 35,001 Basic net income per share$0.76 $0.56 $0.60Diluted net income per share$0.73 $0.55 $0.58(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.(2)For the year ended December 31, 2018, this represents the shares held in escrow pursuant to: (i) the Asset Purchase Agreement with BioPharm Systems,Inc.

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 Code. The Company, at its discretion, matches a portion ofthe employee’s contribution under a predetermined formula based on the level of contribution and years of service. For 2018, the Company made matchingcontributions of 50% (25% in cash and 25% in Company stock) of the first 6% of eligible compensation deferred by the participant. The Companyrecognized $5.6 million, $4.9 million and $4.8 million of expense for the matching cash and Company stock contribution in 2018, 2017 and 2016,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, 2018 and 2017, the deferredcompensation liability balance was $4.5 million and $4.7 million, respectively. The Company funds the deferred compensation plan through company-owned life insurance (“COLI”) policies.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, 2018 and 2017, the defined benefit plan liability, which is unfunded, was immaterial.12. Long-term DebtRevolving Credit FacilityOn June 9, 2017, the Company entered into a Credit Agreement, as amended (the “Credit Agreement”), with Wells Fargo Bank, NationalAssociation, as administrative agent and the other lenders parties thereto. The Credit Agreement provides for revolving credit borrowings up to a maximumprincipal amount of $125.0 million, subject to a commitment increase of $75.0 million. All outstanding amounts owed under the Credit Agreement becomedue 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, 2018, the Company had one outstanding letter of credit for$0.2 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 (5.50% on December 31, 2018) plus a marginranging from 0.00% to 0.50% or one-month LIBOR (2.50% on December 31, 2018) 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, 2018, the Company had $124.8 million of unused borrowing capacity.The Company is required to comply with various financial covenants under the Credit Agreement. Specifically, the Company is required to maintaina ratio of earnings before interest, taxes, depreciation, and amortization (“EBITDA”) plus stock compensation to interest expense for the previous fourconsecutive fiscal quarters of not less than 3.00 to 1.00 and a ratio of54indebtedness to EBITDA plus stock compensation (“Leverage Ratio”) of not more than 3.00 to 1.00. Additionally, the Credit Agreement currently restrictsthe payment of dividends that would result in a pro-forma Leverage Ratio of more than 2.00 to 1.00.At December 31, 2018, the Company was in compliance with all covenants under the Credit Agreement.Convertible Senior Notes due 2023On September 11, 2018, the Company issued $143.8 million aggregate principal amount of the Notes in a private placement to qualifiedinstitutional purchasers pursuant to an exemption from registration provided by Section 4(a)(2) and Rule 144A under the Securities Act of 1933, as amended.The net proceeds from the offerings, after deducting the initial purchasers’ discount and issuance costs of $4.4 million, were $139.4 million. The Companyused (i) $49.0 million of the net proceeds to pay down the Company’s revolving credit facility, (ii) $38.8 million of the net proceeds to repurchase 1.3million shares of the Company’s common stock concurrently with the pricing of the Notes offering in privately negotiated transactions and (iii) $8.6 millionof the net proceeds to fund the cost of entering into the Notes Hedges (as defined below), after such cost was partially offset by the proceeds that theCompany received from entering into the Notes Warrants (as defined below). The remaining proceeds will be used for working capital or other generalcorporate purposes.The Notes bear interest at a rate of 2.375% per year. Interest will be payable in cash on March 15 and September 15 of each year, beginningMarch 15, 2019. The Notes mature on September 15, 2023, unless earlier converted, redeemed or repurchased in accordance with their terms prior to suchdate. The initial conversion rate is 26.5957 shares of the Company’s common stock per $1,000 principal amount of Notes, which is equivalent to an initialconversion price of approximately $37.60 per share of common stock. After consideration of the Notes Hedges and Notes Warrants, the conversion rate iseffectively hedged to a price of $46.62 per share of common stock. The conversion rate, and thus the conversion price, may be adjusted under certaincircumstances as described in the indenture governing the Notes (the “Indenture”). The Company may settle conversions by paying or delivering, asapplicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election, based on the applicableconversion rate(s). If a “make-whole fundamental change” (as defined in the Indenture) occurs, then the Company will in certain circumstances increase theconversion rate for a specified period of time. The Company’s intent is to settle the principal amount of the Notes in cash upon conversion.A Note may be converted at the holder’s option prior to the close of business on the business day immediately preceding September 15, 2023, butonly under the following circumstances:•during any calendar quarter commencing after the calendar quarter ending on December 31, 2018, if the last reported sale price per share of theCompany’s common stock exceeds 130% of the conversion price for each of at least 20 trading days during the 30 consecutive trading days endingon, and including, the last trading day of the immediately preceding calendar quarter;•during the five consecutive business days immediately after any 10 consecutive trading day period (such 10 consecutive trading day period, the“measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on suchtrading day;•upon the occurrence of certain corporate events or distributions on the Company’s common stock described in the Indenture; and•at any time from, and including, March 15, 2023 until the close of business on the second scheduled trading day immediately before the maturitydate.The Company may not redeem the Notes at its option before maturity. If a “fundamental change” (as defined in the Indenture) occurs, then, except asdescribed in the Indenture, noteholders may require the Company to repurchase their notes at a cash repurchase price equal to the principal amount of theNotes to be repurchased, plus accrued and unpaid interest, if any.As of December 31, 2018, none of the conditions permitting holders to convert their Notes had been satisfied and no shares of the Company’scommon stock had been issued in connection with any conversions of the Notes. Based on the closing price of our common stock of $22.26 per share onDecember 31, 2018, the conversion value of the Notes was less than the principal amount of the Notes outstanding on a per Note basis.In accordance with accounting for debt with conversion and other options, the Company bifurcated the principal amount of the Notes into liabilityand equity components. The initial liability component of the Notes was valued at $122.9 million based on the contractual cash flows discounted at anappropriate comparable market non-convertible debt borrowing rate at the date of issuance of 5.7%. The equity component representing the conversionoption and calculated as the residual amount of the proceeds was recorded as an increase in additional paid-in capital within stockholders’ equity of $20.9million, partially offset by the55associated deferred tax effect of $5.4 million. The amount recorded within additional paid-in capital is not to be remeasured as long as it continues to meetthe conditions for equity classification. The resulting debt discount of $20.9 million is being amortized to interest expense using the effective interestmethod with an effective interest rate of 5.7% over the period from the issuance date through the contractual maturity date of September 15, 2023. TheCompany utilizes the treasury stock method to calculate the effects of the Notes on diluted earnings per share.Issuance costs totaling $4.8 million were allocated pro rata based on the relative fair values of the liability and equity components. Issuance costs of$4.1 million attributable to the liability component were recorded as a direct deduction from the carrying value of the Notes and are being amortized tointerest expense using the effective interest method over the term of the Notes. Issuance costs of $0.7 million attributable to the equity component wererecorded as a charge to additional paid-in capital within stockholders’ equity, partially offset by the associated deferred tax effect of $0.2 million. Theunamortized issuance costs are being amortized over a weighted-average remaining period of approximately five years.The liability and equity components of the Notes consisted of the following (in thousands): As of December 31, 2018Liability component: Principal$143,750 Less: Unamortized debt discount(19,806) Unamortized debt issuance costs(3,877)Net carrying amount$120,067 Equity component: Debt discount for conversion option, net of taxes$15,547 Less: Issuance costs, net of taxes(523)Net carrying amount$15,024Interest expense for the year ended December 31, 2018 related to the Notes consisted of the following (in thousands): Year Ended December 31, 2018Coupon interest$1,043Amortization of debt discount1,111Amortization of debt issuance costs252 Total interest expense recognized$2,4062023 Convertible Notes HedgesIn connection with the issuance of the Notes, the Company entered into privately negotiated convertible note hedge transactions (the “NotesHedges”) with certain of the initial purchasers or their respective affiliates and/or other financial institutions (the “Option Counterparties”). The Notes Hedgesprovide the Company with the option to acquire, on a net settlement basis, approximately 3.8 million shares of common stock at a strike price of $37.60,which is equal to the number of shares of common stock that notionally underlie the Notes and corresponds to the conversion price of the Notes. If theCompany elects cash settlement and exercises the Notes Hedges, the aggregate amount of cash received from the Option Counterparties will cover theaggregate amount of cash that the Company would be required to pay to the holders of the Notes, less the principal amount thereof. The Notes Hedges do notmeet the criteria for separate accounting as a derivative as they are indexed to the Company’s stock and are accounted for as freestanding financialinstruments. The Notes Hedges were recorded as a reduction in additional paid-in capital within stockholders’ equity of $20.7 million, partially offset by thedeferred tax effect of $5.3 million.2023 Convertible Notes WarrantsIn connection with the issuance of the Notes, the Company also sold net-share-settled warrants (the “Notes Warrants”) in privately negotiatedtransactions with the Option Counterparties. The strike price of the Notes Warrants was approximately $46.62 per share, and is subject to certain adjustmentsunder the terms of the Notes Warrants. As a result of the Notes Warrants and related transactions, the Company is required to recognize incremental dilutionof earnings per share to the extent the average share price is over $46.62 for any fiscal quarter. The Notes Warrants expire over a period of 100 trading dayscommencing on56December 15, 2023 and may be settled in net shares of common stock or net cash at the Company’s election. The Notes Warrants were recorded as anincrease in additional paid-in capital within stockholders’ equity of $12.1 million.13. Income TaxesThe Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Internal Revenue Service (the“IRS”) has completed examinations of the Company’s U.S. income tax returns or the statute of limitations has passed on returns for the years through 2010.The Company’s 2011 through 2015 U.S. income tax returns are currently under examination by the IRS. The IRS has sought to disallow research credits inthe total amount of $2.5 million on the Company’s 2011, 2012 and 2013 U.S. income tax returns. The Company has exhausted all administrative appealsand formal mediation and has filed suit to resolve this dispute. The Company is awaiting a new court date to be set by the U.S. Tax Court for the 2011through 2013 returns. The Company believes the research credits taken are appropriate and intends to vigorously defend its position. An amount ofadjustment, if any, and the timing of such adjustment are not reasonably possible to estimate at this time. The total amount of research credits taken orexpected to be taken in the Company’s income tax returns for 2011 through December 31, 2018 is $10.6 million.As of December 31, 2018, the Company had U.S. federal tax gross net operating loss carry forwards of approximately $1.5 million that will begin toexpire in 2023 if not utilized. Utilization of net operating losses may be subject to an annual limitation due to the “change in ownership” provisions of theCode. The annual limitation may result in the expiration of net operating losses before utilization.Significant components of the provision for income taxes are as follows (in thousands): Year Ended December 31, 2018 2017 2016Current: Federal$4,030 $9,095 $3,733State1,222 1,262 720Foreign1,183 2,345 1,207Total current6,435 12,702 5,660 Deferred: Federal835 (3,726) 3,487State250 (684) 642Foreign293 270 261Total deferred1,378 (4,140) 4,390Total provision for income taxes$7,813 $8,562 $10,050The components of pretax income for the years ended December 31, 2018, 2017 and 2016 are as follows (in thousands): Year Ended December 31, 2018 2017 2016Domestic$27,613 $21,285 $24,564Foreign4,759 5,858 5,945Total$32,372 $27,143 $30,509For the years ended December 31, 2018, 2017 and 2016 foreign operations included India, China, Canada and the United Kingdom.Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reportingpurposes and the amounts used for income tax purposes. Significant components of the Company’s deferred taxes as of December 31, 2018 and 2017 are asfollows (in thousands):57 December 31, 2018 2017Deferred tax assets: Accrued liabilities$1,617 $2,027Allowance for doubtful accounts208 328Net operating losses375 483Deferred compensation liability2,443 2,579Intangible assets5,769 4,097Total deferred tax assets10,412 9,514Deferred tax liabilities: Prepaid expenses933 902Accounting method change711 1,366Goodwill and intangible assets17,170 13,975Property and equipment851 631Total deferred tax liabilities19,665 16,874Net deferred tax liability$9,253 $7,360Management regularly assesses the likelihood that deferred tax assets will be recovered from future taxable income. To the extent managementbelieves that it is more likely than not that a deferred tax asset will not be realized, a valuation allowance is established. Management believes it is morelikely than not that the Company will generate sufficient taxable income in future years to realize the benefits of its deferred tax assets.The federal corporate statutory tax rate is reconciled to the Company’s effective income tax rate as follows: Year Ended December 31, 2018 2017 2016Federal statutory rate21.0 % 35.0 % 35.0 %State taxes, net of federal benefit4.5 3.3 3.9Effect of foreign operations1.5 1.9 (2.1)Foreign toll charge - U.S. tax reform— 4.1 —Stock compensation2.0 1.9 2.4Non-deductible acquisition costs0.2 — —Research and development tax credit(5.0) (1.0) (5.0)U.S. domestic production deduction(0.1) (1.6) (1.4)Adjustment to deferred tax rate - U.S. tax reform— (12.3) —Other— 0.2 0.1Effective tax rate24.1 % 31.5 % 32.9 %The effective income tax rate decreased to 24.1% for the year ended December 31, 2018 from 31.5% for the year ended December 31, 2017 primarilydue to the reduction of the federal corporate tax rate in 2018 as a result of the 2017 Tax Act. The effective rate for the year ended December 31, 2017included the effects of certain foreign withholding taxes, a foreign toll charge on historic foreign earnings, and a revaluation of ending deferred income taxescaused by passage of the 2017 Tax Act.In general, it is the Company’s practice and intention to reinvest the earnings of the Company’s foreign subsidiaries in those operations. 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. The Company may repatriate available earnings from time to time.Management intends to continue to permanently reinvest all other remaining current and prior earnings 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 31,2018, the aggregate unremitted58earnings of the Company’s foreign subsidiaries for which a deferred income tax liability has not been recorded was approximately $8.5 million, and theunrecognized deferred tax liability on unremitted earnings was approximately $0.5 million.Under the provisions of the ASC Section 740-10-25, the Company had an unrecognized tax benefit of $3.2 million (excluding $0.3 million ofinterest) and $2.7 million (excluding $0.2 million of interest) as of December 31, 2018 and 2017, respectively. If the Company’s assessment of unrecognizedtax benefits is not representative of actual outcomes, the Company’s consolidated financial statements could be significantly impacted in the period ofsettlement or when the statute of limitations expires.The following table is a reconciliation of beginning and ending balances of total amounts of gross unrecognized tax benefits (in thousands): December 31, 2018 2017Balance at beginning of year$2,680 $1,164Additions based on tax positions related to current year554 464Additions based on tax positions related to prior years— 1,151Reductions for tax positions of prior years(69) (99)Balance at end of year$3,165 $2,680U.S. Tax ReformOn December 22, 2017, the U.S. government enacted the 2017 Tax Act. 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 were 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.The SEC 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. During the third quarter of 2018, the Company finalized and filed its 2017 income tax return. There were no materialchanges to the original estimate, and the one-year measurement period is now closed.14. DerivativesIn 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 loss of $0.1 million during the year ended December 31, 2018, and a net gain of $0.1 million during the yearended December 31, 2017. Gains and losses on these contracts are recorded in net other expense (income) and net interest expense in the ConsolidatedStatements 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):59 December 31, 2018 2017Derivatives not designated as hedges Foreign exchange contracts$3,195 $3,979Total derivatives not designated as hedges$3,195 $3,979Derivatives 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.15. Fair Value MeasurementsThe fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable.Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sourceswhile unobservable inputs reflect a reporting entity’s pricing 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 principally from orcorroborated 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 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.All highly liquid investments with maturities at date of purchase of three months or less are considered to be cash equivalents. Based on their short-term nature, the carrying value of cash equivalents approximate their fair value. As of December 31, 2018, $37.7 million of the Company’s cash and cashequivalents balance related to money-market fund investments. These short-term money-market funds are considered Level 1 investments.The Company estimates the fair value of each foreign exchange forward contract by using the present value of expected cash flows. The estimatetakes into account the difference between the current market forward price and contracted forward price for each foreign exchange contract and applies thedifference in the rates to each outstanding contract. Valuations for all derivatives fall within Level 2 of the GAAP valuation hierarchy. The fair value of theCompany’s derivative instruments outstanding as of December 31, 2018 was immaterial.The Company has contingent consideration liabilities related to acquisitions which are measured on a recurring basis and recorded at fair value,determined using the discounted cash flow method. The inputs used to calculate the fair value of the contingent consideration liabilities are considered to beLevel 3 inputs due to the lack of relevant market activity and significant management judgment. An increase in future cash flows may result in a higherestimated fair value while a decrease in future cash flows may result in a lower estimated fair value of the contingent consideration liabilities.Remeasurements to fair value are recorded in adjustment to fair value of contingent consideration in the Consolidated Statements of Operations. Refer toNote 7, Balance Sheet Components, for the estimated fair value of the contingent consideration liabilities as of December 31, 2018 and 2017.60The fair value of the Notes is measured using quoted price inputs. The Notes are not actively traded, and thus the price inputs represent a Level 2measurement. As the quoted price inputs are highly variable from day to day, the fair value estimates could significantly increase or decrease.The Notes are carried at their principal amount less unamortized debt discount and issuance costs, and are not carried at fair value at each period end.The original debt discount was calculated at a market interest rate for nonconvertible debt at the time of issuance, which represented a Level 3 fair valuemeasurement. The approximate fair value of the Notes as of December 31, 2018 was $128.3 million, which is estimated on the basis of inputs that areobservable in the market and is considered a Level 2 fair value measurement.16. 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.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 under various operating lease agreements. The Company has the option to extend the term of certain leaseagreements.

Our audit of internal control over financialreporting of the Company also excluded an evaluation of the internal control over financial reporting of the Acquired Businesses.Adoption of New Accounting PronouncementAs discussed in Note 2 to the consolidated financial statements, the Company changed its method of accounting for revenue and certain costs in 2018 due tothe adoption of ASC Topic 606, Revenue from Contracts with Customers.Basis for OpinionsThe Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting,and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on InternalControl over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on theCompany’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company AccountingOversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securitieslaws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonableassurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internalcontrol over financial reporting was maintained in all material respects.Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financialstatements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis,evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles usedand significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internalcontrol over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weaknessexists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performingsuch other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.Definition and Limitations of Internal Control over Financial ReportingA company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reportingand the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. 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, MissouriFebruary 26, 201963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.
