Our Services

ISG specializes in digital transformation services, including automation, cloud and data analytics; sourcing advisory; managed governance and risk services; network carrier services; technology strategy and operations design; change management; market intelligence and technology research and analysis.  ISG supports both private and public sector organizations to transform and optimize their operational environments.  During periods of expansion or contraction, for enterprises large or small, public or private, in the Americas, Europe or Asia Pacific, our services have helped organizations address their most complex operational issues. The functional domain experience of our experts and deep empirical data resources help clients better understand their strategic options. We provide four key lines of service:

 Research.  We utilize our extensive experience and proprietary data assets to provide subscription and custom research services to senior business and IT executives, technology and software vendors and business/IT services providers. Our mission is to help our clients make better business decisions and create new business value through trusted and objective insights into the key market trends and emerging technologies driving real change. Our combined data sources, compiled from over 30 years of servicing global corporations, provide a rich source of benchmark data into the comparative cost and quality of operational alternatives. For enterprise clients, we use these data sources to provide them with in‑depth analysis into the implications of different service strategies, allowing them to compare and contrast and make informed decisions regarding strategic change. For service providers, our views into the buying behaviors, needs and objectives of global corporations examining transformation of their operations provide unique insights that help them tailor and market their offerings to these enterprises. ISG’s research will continue to play a supporting role for digital services with the production of our Index Reports which include coverage of technology providers, SaaS providers, Cloud and automation platforms in addition to the traditional service provider outsourcing industry.

 Consulting.  We help private and public sector organizations transform and optimize their operational environments with a complete range of consulting services, focusing on information technology, business process transformation, program management services and enterprise resource planning. ISG consulting services include: Business Advisory Services, Data & Analytics, Digital Solutions, Network Advisory Services, Operating Model Design & Implementation, Operations Benchmarking, Organizational Change Management, Performance Management, Qualitative Assessment, Renegotiations, RFX Services, Robotic Process and Cognitive Automation, Software Advisory Services, Strategy, Transition and Transformation.   We assist clients with envisioning, designing and implementing change in their operational environments. We evaluate existing practices and operating costs, identifying potential improvement opportunities to enhance service delivery, optimize operations or reduce costs. Solutions are customized by a client situation and may include internal transformation, the adoption of external strategies, or some combination of both. In all cases, we assist with the selection, implementation and ongoing support for these strategic initiatives.

 Managed Services.  Our Managed Services offerings helps clients realize the cost savings and operating efficiencies they expect from their sourcing arrangements. We provide operational governance services to our clients to ensure seamless end‑to‑end service. Our systems, tools and controls are designed to consistently govern third-party agreements, and our expertise in service integration and management helps clients achieve operational excellence in multi-supplier environments.  These offerings assist clients with monitoring and managing their supplier relationships, providing them with real‑time accurate market intelligence and insights into all aspects of provider performance and cost, allowing them to focus on the more strategic aspects of supplier management.

 Events.  ISG Events offers a range of industry-leading conferences including,  the ISG Sourcing Industry Conference (SIC) series, the premier annual event for service and technology providers in the Americas, EMEA and India; the ISG Executive Provider Summit, a high-value gathering of C-suite provider executives and ISG partners; the ISG Digital Business Summit series, regional events focused on emerging business technologies; the ISG Automation Summit, a conference focused on the latest trends in automation; and the ISG Paragon Awards™, honoring organizations for their contributions to the continuing evolution of sourcing.

Our Competitive Advantages

We believe that the following strengths differentiate us from our competition:

 Independence and Objectivity.  We are not a service provider. We are an independent, fact‑based data, analytics and advisory firm with no material conflicting financial or other interests. This enables us to maintain a trusted advisor relationship with our clients through our unbiased focus and ability to align our interests with those of our clients.

 Domain Expertise.  Averaging over 20 years of experience, our strategic consulting teams bring a wealth of industry and domain‑specific knowledge and expertise to address our clients’ most complex transformational needs.

 Strong Brand Recognition.  ISG continues to gain marketplace traction as a leading brand in our industry.  ISG offers an integrated product and service offering for our clients.

 Proprietary Data Assets and Market Intelligence.  We have assembled a comprehensive and unique set of data, analytics and market intelligence built over more than thirty years of data collection and analysis, providing insight into the comparative cost and quality of a variety of operational alternatives.

 Global Reach.  We possess practical experience in global business operations, and we understand the significance of interconnected economies and companies. Our resources in the Americas, Europe and Asia Pacific make us a truly global advisory firm able to consistently serve the strategic and implementation needs of our clients.

We believe that the strengths disclosed above are central to our ability to deal successfully with the challenges that we face.

Our Strategy

We intend to use our competitive strengths to develop new services and products, sustain our growth and strengthen our existing market position by pursuing the following strategies:

 Preserve and Expand Our Market Share Positions.  We expect the trend toward globalization and greater operating efficiency and technological innovation to play an increasing role in the growth of demand for our services.  We plan to leverage our combined operating platform to serve the growing number of private and public enterprises utilizing outside advisors when undertaking transformational projects. We are focused on growing our existing client base with broader services.  In addition, we will seek to continue to expand our products and services and the geographic markets we serve opportunistically as global competition spurs demand for cost savings and value creation.

 Strengthen Our Industry Expertise.  We have strengthened our market facing organization to drive increased revenue around seven key areas — (i) Banking and Financial Services; (ii) Insurance; (iii) Manufacturing, Communications and Multimedia; (iv) Energy, Life Sciences and Healthcare;  (v) Technology; (vi) Consumer Industries Group; (vii) Private Equity; and (viii) Public Sector/Government.

 Expand Geographically.  Historically, we generated the majority of our revenues in North America.  Beginning in 2011, we made significant investments in Europe and Asia Pacific to capitalize on emerging demand for advisory, benchmarking and analytical insight in these geographic regions. During 2018, we realized the benefits of our previous investments in Europe, which resulted in double-digit revenue growth.

 Aggressively Expand Our Market Focus.  We are seeking to drive our service portfolio and relationships with clients further into: Digital Advisory Services including Cloud Solutions, Automation, Business Advisory Services, Strategy, Data & Analytics, Transition and Organization & Operations are all areas where we are investing additional focus to drive increased revenues and expanded relationships with clients.

 Further Develop Digital and Cloud Competency.  There is a nexus of distinct, yet complementary, technology trends that are creating a perfect storm of disruption for some companies. Among the most significant technology trends are the speed with which products get to market, large‑scale digitization, the efficiency of the cloud and the immediacy with which new disruptors can become omnipresent. ISG plans to expand resources and intellectual property (“IP”) around digitization and the cloud. Digitization is the ‘softwarization’ of business. Processes that were once executed over analog channels (such as phone and ‘real life’) increasingly happen over software. Also, digitization has elevated the profile of software. Software no longer merely supports business processes, but is central to the enterprise strategy.   Our purpose in the digital marketplace is to be the trusted advisor, guiding our clients through the digital transformation toward practical innovation of their business models, leveraging strategic partners, emerging technology and thought leadership.

Our digital services now span a volume of offerings and have become embedded as part of even our traditional transaction service. Advancements continue to be made to ‘digitize’ further our traditional services.  For example, we have continued the modernization of our traditional sourcing services toward digital through with the launch of ISG FutureSource TM approach in 2017, which

has brought agility and nimbleness to the process of sourcing, RFP’s and contracting.  We have also expanded the reach of ISG GovernX TM . This proprietary ISG software platform continues to drive broader insights from additional market and performance data, while delivering increased value to our clients.  ISG Governance Services now are deployed using automation, cognitive and other digital technologies to greatly enhance the value and quality of service given to our clients.  Our digital service offerings also include Robotic Process and Cognitive Automation Technology where we help clients navigate the myriad challenges, risks and opportunities from software selection to building their bot workforce to leverage the technology to transform and improve business outcomes.

 Expand Emerging Services .  The focus will be on creating repeatable methods used to drive growth of emerging services including Robotic Process and Cognitive Automation Technology, Engineering Services and Service Providers as a Business.

1. Robotic Process and Cognitive Automation Technology:  ISG’s capabilities and service offerings include implementation services for Robotic Process and Cognitive Automation Technology.  The Automation market size is expected to grow significantly over the next few years.  Robotic Process Automation (“RPA”) is fundamentally reshaping the world of Information Technology Outsourcing (“ITO”) and Business Process Outsourcing (“BPO”). Increasingly mature RPA solutions are enabling automated 24/7/365 execution of business processes at a fraction of the cost of human equivalents, as well as the potential to dramatically reengineer and improve key business processes. We help customers and service providers navigate the myriad risks and seize the significant transformational opportunities offered by robotics and automation.  Our solutions will work to optimize repetitive processes using ‘bots’ instead of human labor.  RPA services will continue to be marketed by industry (e.g. claims processing for insurance) and by back office functions (e.g. accounting).

2. Engineering Services:  We will continue to advance our position, bringing together solutions that leverage digital advancements for engineering services. Our digitally focused engineering services of the future will allow our clients to rapidly harness the power of Internet of Things (“IoT”), enabling the digitization of products, platforms and processes.

3. HR Technology & Delivery Services: Advances in technology are transforming the business of HR. From intuitive and mobile self-service software to predictive analytics and integrated talent management suites, technological solutions are changing the way leaders acquire, develop and engage their employees. New applications, enhanced functionality and competition among software providers make it difficult to stay on top of this ever-evolving space. ISG provides deep subject matter expertise, market data and financial frameworks to help organizations develop and execute HR technology strategies that are right for them.

4. Providers as a Business (“PaaB”):  Historically, ISG had targeted traditional service providers for these types of services, which included a combination of consulting and research solutions.  These services include market intelligence, client retention programs, pursuit effectiveness, satisfaction benchmarking, go-to-market consulting and health checks.

 Expand “Recurring Revenue Streams.”  These include such annuity-based ISG offerings as Managed Services, Research, Software as a Subscription (RPA licenses), Benchmarking as a Subscription and the multi-year Public Sector contracts. All are characterized by subscriptions (i.e., renewal‑centric as opposed to project centric revenue streams) or multi‑year contracts.  As companies begin to recognize the importance of managing the post‑sourcing‑transaction period, managed services has emerged as a revenue driver for us where our offerings are delivered through multi‑year managed services contracts. We believe that our experience with outsourcing transactions and software implementation initiatives make us uniquely equipped to provide research insights and direct support to help our clients manage their transformational projects or act as a third‑party administrator.  We will continue to pursue opportunities to leverage our experience to make research and managed services an even greater revenue generator for us. The U.S. public sector, particularly state governments, local municipalities, and higher education—presents a significant opportunity to ISG. Systems are typically outdated, maintenance is expensive, and the workforce charged with maintenance is ageing. There is a need to refurbish systems to reduce the cost of operations (particularly because governments’ tax revenues are under pressure). We are well-positioned as a third party, objective advisory group with no affiliation to the software providers.  ISG will continue to invest in the digitization of these services, driving up automation, greater profitability and even more value for our clients. ISG continues to invest in the digitization of these services, leveraging automation and cognitive technologies to deliver greater value to our clients

 Consider Acquisition and Other Growth Opportunities.  The business services, information and advisory market is highly fragmented.  We believe we are well‑positioned to leverage our leading market positions and strong brand recognition to expand through acquisitions. Acquiring firms with complementary services and products allows us to further develop and broaden our service offerings and domain expertise.  We will consider and may pursue opportunities to enter into joint ventures and to buy or combine with other businesses.

 Retool Our Resource and Delivery Model.  The goal is to evolve our workforce to achieve a more efficient distribution of resources globally and a more flexible staffing model. This will provide ISG’s clients with better value for their money while also improving ISG’s margins.

Our Proprietary Data Assets and Market Intelligence

One of our core assets is the information, data, analytics, methodologies and other intellectual property the Company possesses. This intellectual property underpins the independent nature of our operational assessments, strategy development, deal‑structuring, negotiation and other consulting services we provide to our clients.

With each engagement we conduct, we enhance both the quantity and quality of the intellectual property we employ on behalf of our clients, thus providing a continuous, evolving and unique source of information, data and analytics.

This intellectual property is proprietary and we rely on multiple legal and contractual provisions and devices to protect our intellectual property rights.  We recognize the value of our intellectual property and vigorously defend it.  As a result, the Company maintains strict policies and procedures regarding ownership, use and protection with all parties, including our employees.

Clients

We operate in over 20 countries and across numerous industries. Our private sector clients operate primarily in the financial services, telecommunications, healthcare and pharmaceuticals, manufacturing, transportation and travel and energy and utilities industries.  Our private sector clients are primarily large businesses ranked in the Forbes Global 2000 companies annually. Our public sector clients are primarily state and local governments (cities and counties) and authorities (airport and transit) in the United States and national and provincial government units in the United Kingdom, Italy and Australia.

Competition

Competition in the sourcing, data, information and advisory market is primarily driven by independence and objectivity, expertise, possession of relevant benchmarking data, breadth of service capabilities, reputation and price. We compete with other sourcing advisors, research firms, strategy consultants and sourcing service providers. A significant number of independent sourcing and advisory firms offer similar services. In our view, however, these firms generally lack the benchmarking data, scale and diversity of expertise that we possess. In addition, most research firms do not possess the data repository of recent, comparable transactions and benchmarking data. Management consultants bring strategic service capabilities to the sourcing and advisory market. However, they generally lack the depth of experience that sourcing, data and advisory firms such as ISG possess. In addition, management consultants do not possess the sourcing and technology implementation expertise nor the benchmarking data capabilities that are critical to implementing and managing successful transformational projects for businesses and governments. Other service providers often lack the depth of experience, competitive benchmarking data and independence critical to playing the role of “trusted advisor” to clients.

Employees

As of December 31, 2018, we employed 1,310 people worldwide.

Our employee base includes executive management, service leads, partners, directors, advisors, analysts, technical specialists and functional support staff.

We recruit advisors from service providers and consulting firms with direct operational experience. These advisors leverage extensive practical expertise derived from experiences in corporate leadership, consulting, research, financial analysis, contract negotiations and operational service delivery.

All employees are required to execute confidentiality, conflict of interest and intellectual property agreements as a condition of employment. There are no collective bargaining agreements covering any of our employees.

Our voluntary advisor turnover rate has ranged between 8% and 22% over the last three years.

sales. Our ability to pay the fixed costs associated with our debt obligations will depend on our operating performance and cash flow, which in turn depend on general economic conditions and the advisory services market. A failure to pay interest or indebtedness when due could result in a variety of adverse consequences, including the acceleration of our indebtedness.  In such a situation, it is unlikely that we would be able to fulfill our obligations under or repay the accelerated indebtedness or otherwise cover our fixed costs. As of December 31, 2018, the total principal outstanding under the term loan facility and revolving credit facility was $95.1 million and $4.0 million, respectively.

Our failure to comply with the covenants in our credit agreement could materially and adversely affect our financial condition and liquidity.

Our credit agreement contains financial covenants requiring that we maintain, among other things, certain levels of debt coverage and fixed charges. Poor financial performance could cause us to be in default of these covenants.  While we were in compliance with these covenants at December 31, 2018, there can be no assurance that we will remain in compliance in the future.  If we fail to comply with the covenants in our credit agreement, this could result in our having to seek an amendment or waiver from our lenders to avoid the termination of their commitments and/or the acceleration of the maturity of outstanding amounts under the credit facility.  The cost of our obtaining an amendment or waiver could be significant, and further, there can be no assurance that we would be able to obtain an amendment or waiver. If our lenders were unwilling to enter into an amendment or provide a waiver, all amounts outstanding under our credit facility would become immediately due and payable.

We have risks associated with acquisitions or investments.

Since our inception, we have expanded through acquisitions. In the future, we plan to pursue additional acquisitions and investments as opportunities arise.  We may not be able to successfully integrate businesses that we acquire in the future without substantial expense, delays or other operational or financial problems. We may not be able to identify, acquire or profitably manage additional businesses.  If we pursue acquisition or investment opportunities, these potential risks could disrupt our ongoing business, result in the loss of key customers or personnel, increase expenses and otherwise have a material adverse effect on our business, results of operations and financial condition.

Difficulties in integrating businesses we have acquired, or may acquire in the future may demand time and attention from our senior management.

Integrating businesses we have acquired, or may acquire in the future may involve unanticipated delays, costs and/or other operational and financial problems. In integrating acquired businesses, we may not achieve expected economies of scale or profitability, or realize sufficient revenue to justify our investment.  If we encounter unexpected problems as we try to integrate an acquired firm into our business, our management may be required to expend time and attention to address the problems, which would divert their time and attention from other aspects of our business.

Our operating results have been, and may in the future be, adversely affected by worldwide economic conditions and credit tightening.

Our results of operations are affected by the level of business activity of our clients, which in turn is affected by the level of economic activity in the industries and markets that they serve. A decline in the level of

business activity of our clients could have a material adverse effect on our revenue and profit margin.  Future economic conditions could cause some clients to reduce or defer their expenditures for consulting services. We have implemented and will continue to implement cost‑savings initiatives to manage our expenses as a percentage of revenue. However, current and future cost‑management initiatives may not be sufficient to maintain our margins if the economic environment should weaken for a prolonged period.

The rate of growth in the broadly defined business information services & advisory sector and/or the use of technology in business may fall significantly below the levels that we currently anticipate.

Our business is dependent upon continued growth in sourcing activity, the use of technology in business by our clients and prospective clients and the continued trend towards sourcing of complex information technology and business process tasks by large and small organizations. If sourcing diminishes as a management and operational tool, the growth in the use of technology slows down or the cost of sourcing alternatives rises, our business could suffer. Companies that have already invested substantial resources in developing in‑house information technology and business process functions may be particularly reluctant or slow to move to a sourcing solution that may make some of their existing personnel and infrastructure obsolete.

Our engagements may be terminated, delayed or reduced in scope by clients at any time.

Our clients may decide at any time to abandon, postpone and/or to reduce our involvement in an engagement.  Our engagements can be terminated, or the scope of our responsibilities may be diminished, with limited advance notice. If an engagement is terminated, delayed or reduced unexpectedly, the professionals working on the engagement could be underutilized until we assign them to other projects. Accordingly, the termination or significant reduction in the scope of a single large engagement, or multiple smaller engagements, could harm our business results.

Our operating results may fluctuate significantly from period to period as a result of factors outside of our control.

Our revenues and operating results may vary significantly from accounting period to accounting period due to factors including:

 fluctuations in revenues earned on contracts;

 commencement, completion or termination of engagements during any particular period;

 additions and departures of key advisors;

 transitioning of advisors from completed projects to new engagements;

 seasonal trends;

 introduction of new services by us or our competitors;

 changes in fees, pricing policies or compensation arrangements by us or our competitors;

 strategic decisions by us, our clients or our competitors, such as acquisitions, divestitures, spin‑offs, joint ventures, strategic investments or changes in business strategy;

 global economic and political conditions and related risks, including acts of terrorism; and

 conditions in the travel industry that could prevent our advisors from traveling to client sites.

We depend on project‑based advisory engagements, and our failure to secure new engagements could lead to a decrease in our revenues.

Advisory engagements typically are project‑based. Our ability to attract advisory engagements is subject to numerous factors, including the following:

 delivering consistent, high‑quality advisory services to our clients;

 tailoring our advisory services to the changing needs of our clients;

 matching the skills and competencies of our advisory staff to the skills required for the fulfillment of existing or potential advisory engagements; and

 maintaining a global business operation.

Any material decline in our ability to secure new advisory arrangements could have an adverse impact on our revenues and financial condition.

If we are unable to achieve or maintain adequate utilization for our consultants, our operating results could be adversely impacted.

Our profitability depends to a large extent on the utilization of our consultants. Utilization of our consultants is affected by a number of factors, including:

 additional hiring of consultants because there is generally a transition period for new consultants;

 the number and size of client engagements;

 the unpredictability of the completion and termination of engagements;

 our ability to transition our consultants efficiently from completed engagements to new engagements;

 unanticipated changes in the scope of client engagements; and

 our ability to maintain an appropriate level of consultants by forecasting the demand for our services.

We could lose money on our fixed‑fee contracts.

As part of our strategy, from time to time, we enter into fixed fee contracts, in addition to contracts based on payment for time and materials. Because of the complexity of many of our client engagements, accurately estimating the cost, scope and duration of a particular engagement can be a difficult task. If we fail to make accurate estimates, we could be forced to devote additional resources to these engagements for which we will not receive additional compensation. To the extent that an expenditure of additional resources is required on an engagement, this could reduce the profitability of, or result in a loss on, the engagement.

Our contracts with contingent-based revenue may cause unusual variations in our operating results.

As part of our strategy, from time to time, we earn incremental revenues, in addition to hourly or fixed fee billings, which are contingent on the attainment of certain contractual milestones or objectives.  Because it is uncertain when the milestones or objectives will be achieved, if ever, any such incremental revenues may cause unusual variations in quarterly revenues and operating results.  Also, whether any contractual milestones or objectives are achieved may become subject to dispute.

We may not be able to maintain our existing services and products.

We operate in a rapidly evolving market, and our success depends upon our ability to deliver high quality advice and analysis to our clients. Any failure to continue to provide credible and reliable information and advice that is useful to our clients could have a significant adverse effect on future business and operating results. Further, if our advice proves to be materially incorrect and the quality of service is diminished, our reputation may suffer and demand for our services and products may decline. In addition, we must continue to improve our methods for delivering our products and services in a cost‑effective manner.

Expanding our service offerings may not be profitable.

We may choose to develop new service offerings because of market opportunities or client demands. Developing new service offerings involves inherent risks, including:

 a  lack of market understanding;

 competition from more established market participants;

 our inability to estimate demand for the new service offerings; and

 unanticipated expenses to hire qualified consultants and to market our new service offerings.

If we cannot manage the risks associated with new service offerings effectively, we are unlikely to be successful in these efforts, which could harm our ability to sustain profitability.

We may not have the ability to develop and offer the new services and products that we need to remain competitive.

Our future success will depend in part on our ability to offer new services and products. To maintain our competitive position, we must continue to enhance and improve our services and products, develop or acquire new services and products in a timely manner, and appropriately position and price new services and products relative to the marketplace and our costs of producing them. These new services and products must successfully gain market acceptance by addressing specific industry and business sectors and by anticipating and identifying changes in client requirements.  The process of researching, developing, launching and gaining client acceptance of a new service or product, or assimilating and marketing an acquired service or product is risky and costly. We may not be able to introduce new, or assimilate acquired, services and products successfully.  Any failure to achieve successful client acceptance of new services and products could have an adverse effect on our business results.

We may fail to anticipate and respond to market trends.

Our success depends in part upon our ability to anticipate rapidly changing technologies and market trends and to adapt our advice, services and products to meet the changing sourcing advisory needs of our clients. Our clients regularly undergo frequent and often dramatic changes.  That environment of rapid and continuous change presents significant challenges to our ability to provide our clients with current and timely analysis, strategies and advice on issues of importance to them. Meeting these challenges requires the commitment of substantial resources.  Any failure to continue to respond to developments, technologies, and trends in a manner that meets market needs could have an adverse effect on our business results.

We may be unable to protect important intellectual property rights.

We rely on copyright and trademark laws, as well as nondisclosure and confidentiality arrangements, to protect our proprietary rights in our methods of performing our services, our data and our tools for analyzing financial and other information.  There can be no assurance that the steps we have taken to protect our intellectual property rights will be adequate to deter misappropriation of our rights or that we will be able to detect unauthorized use and take timely and effective steps to enforce our rights.  If substantial and material unauthorized uses of our proprietary methodologies, data and analytical tools were to occur, we may be required to engage in costly and time‑consuming litigation to enforce our rights.  There can be no assurance that we would prevail in such litigation. If others were able to use our intellectual property or were to independently develop our methodologies or analytical tools, our ability to compete effectively and to charge appropriate fees for our services may be adversely affected.

We face competition and our failure to compete successfully could materially adversely affect our results of operations and financial condition.

The business information services and advisory sector is highly competitive, fragmented and subject to rapid change. We face competition from many other providers ranging from large organizations to small firms and independent contractors that provide specialized services. Our competitors include any firm that provides sourcing or benchmarking advisory services, IT strategy or business process consulting, which may include a variety of consulting firms, service providers, niche advisors and, potentially, advisors currently or formerly employed by us. Some of our competitors have significantly more financial and marketing resources, larger professional staffs, closer client relationships, broader geographic presence or more widespread recognition than us.

In addition, limited barriers to entry exist in the markets in which we do business. As a result, additional new competitors may emerge and existing competitors may start to provide additional or complementary services. There can be no assurance that we will be able to successfully compete against current and future competitors and our failure to do so could result in loss of market share, diminished value in our products and services, reduced pricing and increased marketing expenditures. Furthermore, we may not be successful if we cannot compete effectively on quality of advice and analysis, timely delivery of information, client service or the ability to offer services and products to meet changing market needs for information, analysis or price.

The loss of key executives could adversely affect our business.

The success of our business is dependent upon the continued service of a relatively small group of key executives, including Mr. Connors, Chairman and Chief Executive Officer; Mr. Lavieri, Vice-Chairman; Mr.

Berger, Executive Vice President, Chief Financial Officer; and Mr. Kucinski, Executive Vice President and Chief Human Resources Officer, among others.

Although we currently intend to retain our existing management, we cannot assure you that such individuals will remain with us for the immediate or foreseeable future.  The unexpected loss of the services of one or more of these executives could adversely affect our business.

We rely heavily on key members of our management team.

We are dependent on our management team. We grant restricted stock units (“RSUs”) from time to time to key employees and, in connection with such grants, require recipients to execute a restrictive covenant agreement. Vested and unvested RSUs will be forfeited upon any violation of the restrictive covenant agreement. We may not be able to retain these managers and may not be able to enforce the restrictive covenants. If we were to lose a number of key members of our management team and were unable to replace these people quickly, we could have difficulty maintaining our growth and certain key relationships with large clients and face competition from these former managers if the restrictive covenants are unenforceable.

We depend upon our ability to attract, retain and train skilled advisors and other professionals.

Our business involves the delivery of advisory and consulting services. Therefore, our continued success depends in large part upon our ability to attract, develop, motivate, retain and train skilled advisors and other professionals who have advanced information technology and business processing domain expertise, financial analysis skills, project management experience and other similar abilities.  These advisors could resign and join one of our competitors or provide sourcing advisory services to our clients through their own ventures.

We must also recruit staff globally to support our services and products. We face competition for the limited pool of these qualified professionals from, among others, technology companies, market research firms, consulting firms, financial services companies and electronic and print media companies, some of which have a greater ability to attract and compensate these professionals. Some of the personnel that we attempt to hire may be subject to non‑compete agreements that could impede our short‑term recruitment efforts.  Any failure to retain key personnel or hire and train additional qualified personnel as required supporting the evolving needs of clients or growth in our business could adversely affect the quality of our products and services, and our future business and operating results.

We may have agreements with certain clients that limit the ability of particular advisors to work on some engagements for a period of time.

We provide services primarily in connection with significant or complex sourcing transactions and other matters that provide potential competitive advantage and/or involve sensitive client information. Our engagement by a client occasionally precludes us from staffing certain advisors on new engagements with other clients because the advisors have received confidential information from a client who is a competitor of the new client.  Furthermore, it is possible that our engagement by a client could preclude us from accepting engagements with such client’s competitors because of confidentiality concerns.

We derive a significant portion of our revenues from our largest clients and could be materially and adversely affected if we lose one or more of our large clients.

Our 25 largest clients accounted for approximately 38% of revenue in 2018 and 39% in 2017.  If one or more of our large clients terminate or significantly reduce their engagements or fail to remain a viable business, then our revenues could be materially and adversely affected.  In addition, sizable receivable balances could be jeopardized if large clients fail to remain a going concern.

Our international operations expose us to a variety of risks that could negatively impact our future revenue and growth.

Approximately 42% and 40% of our revenues for 2018 and 2017 were derived from sales outside of the Americas, respectively.  Our operating results are subject to the risks inherent in international business activities, including:

 tariffs and trade barriers;

 regulations related to customs and import/export matters;

 restrictions on entry visas required for our advisors to travel and provide services;

 tax issues, such as tax law changes and variations in tax laws as compared to the United States;

 cultural and language differences;

 an inadequate banking system;

 foreign exchange controls;

 restrictions on the repatriation of profits or payment of dividends;

 crime, strikes, riots, civil disturbances, terrorist attacks and wars;

 nationalization or expropriation of property;

 law enforcement authorities and courts that are inexperienced in commercial matters; and

 deterioration of political relations with the United States.

Air travel, telecommunications and entry through international borders are all vital components of our business.  If a terrorist attack were to occur, our business could be disproportionately impacted because of the disruption a terrorist attack causes on these vital components.

Further, conducting business abroad subjects us to increased regulatory compliance and oversight. For example, in connection with our international operations, we are subject to laws prohibiting certain payments to governmental officials, such as the Foreign Corrupt Practices Act. A failure to comply with applicable regulations could result in regulatory enforcement actions as well as substantial civil and criminal penalties assessed against us and our employees.

We intend to continue to expand our global footprint in order to meet our clients’ needs. This may involve expanding into countries beyond those in which we currently operate.  We may involve expanding into less developed countries, which may have less political, social or economic stability and less developed infrastructure and legal systems. As we expand our business into new countries, regulatory, personnel,

technological and other difficulties may increase our expenses or delay our ability to start up operations or become profitable in such countries.  This may affect our relationships with our clients and could have an adverse effect on our business.

The uncertainty surrounding the implementation and effect of Brexit may cause increased economic volatility, affecting our operations and business.

Given our operations in the United Kingdom and Continental Europe, we face uncertainty surrounding the implementation and effects of the U.K.’s June 2016 referendum in which voters approved the United Kingdom’s exit from the European Union, commonly referred to as “Brexit.” It is possible that Brexit will cause increased regulatory and legal complexities and create uncertainty surrounding our business, including our relationships with existing and future clients, suppliers and employees, which could have an adverse effect on our business, financial results and operations.

Data protection laws and self-regulatory codes may restrict our activities and increase our costs.

Various statutes and rules regulate conduct in areas such as privacy and data protection which may affect our collection, use, storage and transfer of information both abroad and in the United States. Compliance with these laws and self-regulatory codes may require us to make certain investments or may dictate that we not offer certain types of services or only offer such services after making necessary modifications. Failure to comply with these laws and self-regulatory codes may result in, among other things, civil and criminal liability, negative publicity, restrictions on further use of data and/or liability under contractual warranties.

In addition, there is an increasing public concern regarding data and consumer protection issues, with the result that the number of jurisdictions with data protection laws continues to increase and the scope of existing privacy laws and the data considered to be covered by such laws is expanding. Changes in these laws (including newly released interpretations of these laws by courts and regulatory bodies) may limit our data access, use and disclosure, and may require increased expenditures by us or may dictate that we may not offer certain types of services.

The European Union’s General Data Protection Regulation (“GDPR”), which took effect in May 2018, has extra-territorial scope and substantial fines for breaches (up to 4% of global annual revenue or €20 million, whichever is greater).  Additionally, compliance with the GDPR is resulting in operational costs to implement new procedures corresponding to new legal rights granted under the law, but has had little direct impact on ISG products.  ISG is continuing to monitor the development of the EU’s ePrivacy Regulation proposal and industry response and will determine whether to take further action, as needed, following its final adoption.

We operate in a number of international areas which exposes us to significant foreign currency exchange rate risk.

We have significant international revenue, which is predominantly collected in local currency.  We do enter into forward contracts for hedging of specific transactions. All are settled prior to quarter end. It is expected that our international revenues will continue to grow as European and Asian markets adopt sourcing solutions.  The translation of our revenues into U.S. dollars, as well as our costs of operating internationally, may adversely affect our business, results of operations and financial condition.

We may be subject to claims for substantial damages by our clients arising out of disruptions to their businesses or inadequate service and our insurance coverage may be inadequate.

Most of our service contracts with clients contain service level and performance requirements, including requirements relating to the quality of our services. Failure to consistently meet service requirements of a client or errors made by our employees in the course of delivering services to our clients could disrupt the client’s business and result in a reduction in revenues or a claim for damages against us. Additionally, we could incur liability if a process we manage for a client were to result in internal control failures or impair our client’s ability to comply with our own internal control requirements.

Under our service agreements with our clients, our liability for breach of our obligations is generally limited to actual damages suffered by the client and is typically capped at the greater of an agreed amount or the fees paid or payable to us under the relevant agreement.  These limitations and caps on liability may be unenforceable or otherwise may not protect us from liability for damages. In addition, certain liabilities, such as claims of third parties for which we may be required to indemnify our clients or liability for breaches of confidentiality, are generally not limited under those agreements.  Although we have general commercial liability insurance coverage, the coverage may not continue to be available on acceptable terms or in sufficient amounts to cover one or more large claims. The successful assertion of one or more large claims against us that exceed available insurance coverage or changes in our insurance policies (including premium increases or the imposition of large deductible or co‑insurance requirements) could have a material adverse effect on our business.

We could be liable to our clients for damages and subject to liability and our reputation could be damaged if our confidential information or client data is compromised.

We may be liable to our clients for damages caused by disclosure of confidential information. We are often required to collect and store sensitive or confidential client data in order to perform the services we provide under our contracts. Many of our contracts do not limit our potential liability for breaches of confidentiality. If any person, including any of our current or former employees, penetrates our network security or misappropriates sensitive data or if we do not adapt to changes in data protection legislation, we could be subject to significant liabilities to our clients or to our clients’ customers for breaching contractual confidentiality provisions or privacy laws. Also, we could face cyber-based attacks and attempts by hackers and similar unauthorized users to gain access to or corrupt our information technology systems in order to gain access to confidential information and client data. Such attacks could disrupt our business operations, cause us to incur unanticipated losses or expenses, and result in unauthorized disclosures of confidential or proprietary information. Although we seek to prevent, detect and investigate these network security incidents, and have taken steps to mitigate the likelihood of network security breaches, there can be no assurance that attacks by unauthorized users will not be attempted in the future or that our security measures will be effective.  Unauthorized disclosure of sensitive or confidential client data, whether through breach of our processes, systems or otherwise, could also damage our reputation and cause us to lose existing and potential clients. We may also be subject to civil actions and criminal prosecution by government or government agencies for breaches relating to such data. Our insurance coverage for breaches or mismanagement of such data may not continue to be available on reasonable terms or in sufficient amounts to cover one or more large claims against us.

We could have liability or our reputation could be damaged if we fail to protect client and/or our data from security breaches or cyberattacks.

We are dependent on information technology networks and systems to securely process, transmit and store electronic information and to communicate among our locations around the world and with our people, clients, alliance partners and vendors. As the breadth and complexity of this infrastructure continues to grow, including as a result of the use of mobile technologies, social media and cloud-based services, the risk of security breaches and cyberattacks increases. Such breaches could lead to shutdowns or disruptions of or damage to our systems and those of our clients, alliance partners and vendors, and unauthorized disclosure of sensitive or confidential information, including personal data.

Failure to maintain effective internal controls over financial reporting could adversely affect our business and the market price of our Common Stock.

Pursuant to rules adopted by the SEC implementing Section 404 of the Sarbanes Oxley Act of 2002, we are required to assess the effectiveness of our internal controls over financial reporting and provide a management report on our internal controls over financial reporting in all annual reports. This report contains, among other matters, a statement as to whether or not our internal controls over financial reporting are effective and the disclosure of any material weaknesses in our internal controls over financial reporting identified by management.

The Committee of Sponsoring Organizations of the Treadway Commission (COSO) provides a framework for companies to assess and improve their internal control systems. Auditing Standard No. 5 provides the professional standards and related performance guidance for auditors to attest to, and report on, management’s assessment of the effectiveness of internal control over financial reporting under Section 404.  Management’s assessment of internal controls over financial reporting requires management to make subjective judgments and, some of the judgments will be in areas that may be open to interpretation.  Therefore, our management’s report on our internal controls over financial reporting may be difficult to prepare, and our auditors may not agree with our management’s assessment.

While we currently believe our internal controls over financial reporting are effective, we are required to comply with Section 404 on an annual basis. If, in the future, we identify one or more material weaknesses in our internal controls over financial reporting during this continuous evaluation process, our management will be unable to assert such internal controls are effective.  Therefore, if we are unable to assert that our internal controls over financial reporting are effective in the future, or if our auditors are unable to express an opinion on the effectiveness of our internal controls, our investors could lose confidence in the accuracy and completeness of our financial reports, which could have an adverse effect on our business and the market price of our Common Stock.

Impairment to goodwill and other intangible assets could have a material adverse effect on our financial condition and results of operations.

Under generally accepted accounting principles, we are required to perform an annual impairment test at the reporting unit level of our goodwill.  We may need to perform an impairment test more frequently   of goodwill, or perform an impairment test at the asset group level with respect to intangible assets, if events occur or circumstances indicate that the carrying amount of these assets may not be recoverable. These events or circumstances could include a significant change in the business conditions, attrition of key personnel, a prolonged decline in our stock price and market capitalization, legal factors, operating performance indicators, competition and other factors. If the fair market value of our reporting unit is less than the carrying amount of

the related assets, we could be required to record an impairment charge in the future. The valuation of our reporting unit requires judgment in estimating future cash flows, discount rates and other factors.  In making these judgments, we evaluate the financial condition of our reporting unit, including such factors as market performance, changes in our client base and projected growth rates. Because these factors are ever changing, due to market and general business conditions, we cannot predict whether, and to what extent, our goodwill and long-lived intangible assets may be impaired in future periods.  The amount of any future impairment could be significant and could have a material adverse effect on our financial results.

Client restrictions on the use of client data could adversely affect our activities.

The majority of the data we use to populate our databases comes from our client engagements. The insight sought by clients from us relates to the contractual data and terms, including pricing and costs, to which we have access in the course of assisting our clients in the negotiation of our sourcing agreements. Data is obtained through the course of our engagements with clients who agree to contractual provisions permitting us to consolidate and utilize on an aggregate basis such information.  If we were unable to utilize key data from previous client engagements, our business, financial condition and results of operations could be adversely affected.

We may not be able to maintain the equity in our brand name.

We believe that the ISG brand remains critical to our efforts to attract and retain clients and staff and that the importance of brand recognition will increase as competition increases.  We may expand our marketing activities to promote and strengthen our brand and may need to increase our marketing budget, hire additional marketing and public relations personnel, expend additional sums to protect the brand and otherwise increase expenditures to create and maintain client brand loyalty. If we fail to effectively promote and maintain the brand or incur excessive expenses in doing so, our future business and operating results could be adversely impacted.

Our actual operating results may differ significantly from our guidance.

From time to time, we release guidance regarding our future performance that represents our management’s estimates as of the date of release. This guidance, which consists of forward‑looking statements, is prepared by our management and is qualified by, and subject to, the assumptions and the other information contained or referred to in the release. Our guidance is not prepared with a view toward compliance with published guidelines of the Public Company Accounting Oversight Board (United States), and neither our independent registered public accounting firm nor any other independent expert or outside party compiles or examines the guidance and, accordingly, no such person expresses any opinion or any other form of assurance with respect thereto. Guidance is based upon a number of assumptions and estimates that, while presented with numerical specificity, is inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. The principal reason that we release this data is to provide a basis for our management to discuss our business outlook with analysts and investors.  We do not accept any responsibility for any projections or reports published by any such persons.  Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions of the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release.  Actual results will vary from the guidance and the variations may be material. Investors should also recognize that the reliability of any forecasted financial data diminishes the farther in the future that the data is forecast.  In light of the foregoing, investors are urged to put

the guidance in context and not to place undue reliance on it. Any failure to successfully implement our operating strategy or the occurrence of any of the events or circumstances set forth in this Annual Report on Form 10‑K could result in the actual operating results being different than the guidance, and such differences may be adverse and material.

On March 1, 2019, the last reported sale price for our common stock on The Nasdaq Stock Market was $4.39 per share.

As of December 31, 2018, there were 519 holders of record of ISG common stock.  The actual number of stockholders is significantly greater than this number of record holders and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.

Dividend Policy

On December 2, 2014, the Company’s Board of Directors authorized a special dividend of $0.14 per share on the Company’s issued and outstanding shares of common stock.  This cash dividend was paid on January 28, 2015 to shareholders of record as of January 15, 2015. Prior to this special dividend we had not paid any dividends on our common stock. Our Credit Agreement limits our ability to pay dividends.  We amended the Credit Agreement in order to exclude the payment of the special dividend from the calculation of our fixed charge coverage ratio covenant under the Credit Agreement. The payment of dividends in the future will be within the discretion of our Board of Directors and will be contingent upon our revenues and earnings, if any, capital requirements and general financial condition.

Issuer Purchases of Equity Securities

On March 9, 2016, the Company’s Board of Directors approved a share repurchase authorization of up to $15 million.  This new share repurchase program took effect upon completion of the Company’s prior 2014 share repurchase authorization program in 2016.  The shares may be repurchased from time to time in open market transactions at prevailing market prices, in privately negotiated transactions, pursuant to a Rule 10b5-1 repurchase plan or by other means in accordance with federal securities laws. The timing and the amount of any repurchases will be determined by the Company’s management based on its evaluation of market conditions, capital allocation alternatives, and other factors.  There is no guarantee as to the number of shares that will be repurchased, and the repurchase program may be extended, suspended or discontinued at any time without notice at the Company’s discretion.

The following table details the repurchases that were made during the three months ended December 31, 2018.

Securities Authorized for Issuance under Equity Compensation Plan

The following table lists information regarding outstanding options and shares reserved for future issuance under our Amended and Restated 2007 Equity and Incentive Award Plan and our Amended and Restated

Employee Stock Purchase Plan as of December 31, 2018. We have not issued any shares of our common stock to employees as compensation under a plan that has not been approved by our stockholders.

(1) The weighted‑average exercise price includes outstanding options and RSUs, treating RSUs as stock awards with an exercise price of zero.

(2) Includes 440,304 shares available for future issuance under the Company’s Employee Stock Purchase Plan.  Also includes 3,628,021 shares that were available for grant under the Amended and Restated 2007 Equity and Incentive Award Plan as options and SARs and also for restricted stock, restricted stock units or other awards that could provide to the grantee an opportunity to earn the full value of an underlying share (in other words, such earning opportunity is not limited to the appreciation in value of our stock following the grant of the award).

services, including automation, cloud and data analytics; sourcing advisory; managed governance and risk services; network carrier services; technology strategy and operations design; change management; market intelligence and technology research and analysis. Founded in 2006, and based in Stamford, Conn., ISG employs more than 1,300 digital-ready professionals operating in more than 20 countries—a global team known for its innovative thinking, market influence, deep industry and technology expertise, and world-class research and analytical capabilities based on the industry’s most comprehensive marketplace data. For more information, visit www.isg-one.com.

Our strategy is to strengthen our existing market position and develop new services and products to support future growth plans. As a result, we are focused on growing our existing service model, expanding geographically, developing new industry sectors, productizing market data assets, expanding our managed services offerings and growing via acquisitions. Although we do not expect any adverse conditions that will impact our ability to execute against our strategy over the next twelve months, the more significant factors that could limit our ability to grow in these areas include global macro‑economic conditions and the impact on the overall sourcing market, competition, our ability to retain advisors and reductions in discretionary spending with our top client accounts or other significant client events. Other areas that could impact the business would also include natural disasters, legislative and regulatory changes and capital market disruptions.

We principally derive revenues from fees for services generated on a project by project basis. Prior to the commencement of a project, we reach agreement with the client on rates for services based upon the scope of the project, staffing requirements and the level of client involvement. Revenues for services rendered are recognized on a time and materials basis or on a fixed fee or capped fee basis in accordance with accounting and disclosure requirements for revenue recognition.

Revenues for time and materials contracts are recognized based on the number of hours worked by our advisors at an agreed upon rate per hour and are recognized in the period in which services are performed. Revenues for time and materials contracts are billed monthly, semimonthly or in accordance with the specific contractual terms of each project.

We also derive our revenues from recurring revenue streams.  This includes Managed Services, Research, the U.S. Public Sector, subscription services around RPA and analytic benchmarking.  All are characterized by subscriptions (i.e., renewal centric as opposed to project centric revenue streams) or multi-year contracts.  Our digital services now span a volume of offerings and have become embedded as part of even our traditional transaction services.  Digital enablement provides capabilities, digital insights and better engagement with clients and partners.

Our results are impacted principally by our full‑time consultants’ utilization rate, the number of business days in each quarter and the number of our revenue‑generating professionals who are available to work. Our utilization rate can be negatively affected by increased hiring because there is generally a transition period for new professionals that result in a temporary drop in our utilization rate. Our utilization rate can also be affected by seasonal variations in the demand for our services from our clients. The number of business work days is also affected by the number of vacation days taken by our consultants and holidays in each quarter. We typically have fewer business work days available in the fourth quarter of the year, which can impact revenues during that period. Time‑and‑expense engagements do not provide us with a high degree of predictability as to performance in future periods. Unexpected changes in the demand for our services can result in significant variations in utilization and revenues and present a challenge to optimal hiring and staffing. The volume of work performed for any particular client can vary widely from period to period.

EXECUTIVE SUMMARY

2018 was another year of great progress for ISG. Continuing our “Go Digital” journey, we focused our energies on evolving our product and service portfolio to meet the growing digital needs of our clients, while applying those same digital business principles and technologies to improving our own operations.

ISG is in a unique position to help shape the digital future of business for its clients—both buyers and sellers of technology services. Since our founding more than 10 years ago, we have continued to evolve to meet the changing needs of our clients—transforming ourselves from a firm principally focused on sourcing advisory services to one offering a full range of technology research, consulting, managed services and events aimed at helping clients digitally transform their operations for greater efficiency and faster growth.

Clearly, our “Go Digital!” strategy is working. There isn’t a client conversation now that doesn’t include some element of digital, and we are responding by building digital components into each of our service lines. A great example is ISG FutureSource™, our next-generation digital sourcing solution. ISG FutureSource™ reinvents our traditional sourcing services and addresses the need for speed, agility and mastering the increasing complexity of today’s digital sourcing environment.

Some of our services, like ISG Automation, were born digital. ISG Automation is growing in value for both our clients and our firm, as evidenced by the high market valuations being placed on our automation software partners Automation Anywhere, Blue Prism, UiPath and WorkFusion.

Recently we launched ISG Blockchain Now™, a new advisory and sourcing solution that enables our clients to improve the efficiency, accuracy and security of their business processes through distributed ledger technology. We expect our blockchain business to evolve over time, but as with automation, ISG is entering the arena now to create use cases with clients—in preparation for when this technology becomes even more mainstream over the next few years.

We also have been successful growing our recurring-revenue streams. These annuity-like offerings—Managed Services, Research, U.S. Public Sector, Software-as-a-Subscription and Benchmarking-as-a-Subscription. These more predictable revenue streams are highly prized by our shareholders, attract more investment and increase the value of our firm.

ISG Research, meanwhile, continues to bring innovative new solutions to market, including in 2018 alone such new offerings as the ISG Digital Innovation Tour™, ISG Momentum Accelerator™ and the ISG Customer Experience Study. ISG Research also relaunched its ISG Insights™ analyst offering and the enhanced ISG Momentum® Contract KnowledgeBase; continued the global expansion of its ISG Provider Lens™ provider research, and nearly doubled ISG Events. Our research content also is featured on our client-facing ISG Impact™ app, introduced this year. 

on the attainment of certain contractual milestones.  Revenues related to materials (mainly out‑of‑pocket expenses such as airfare, lodging and meals) required during an engagement generally do not include a profit mark‑up and can be charged and reimbursed separately or as part of the overall fee arrangement. Invoices are issued to clients monthly, semimonthly or in accordance with the specific contractual terms of each project.

We operate in one segment, fact‑based sourcing advisory services. We operate principally in the Americas, Europe, and Asia Pacific. Our foreign operations are subject to local government regulations and to the uncertainties of the economic and political conditions of those areas, and the revenue for our foreign operations is predominantly collected in local currency.

Geographical information for the segment is as follows:

Revenues increased by $6.2 million or approximately 2% in 2018.  The increase in revenues in Europe was primarily attributable to growth in our Consulting service line.  The decrease in revenues in the Americas was primarily attributable to a decline in our Consulting service line, including the Public Sector, partially offset by growth attributable to our Managed Services and Events service lines.  The decrease in revenues in Asia Pacific was primarily attributable to a decline in our Managed Services service line.  The translation of foreign currency revenues into U.S. dollars favorably impacted performance compared to the prior year in Europe and Asia Pacific.

Total operating expenses increased by $2.7 million for 2018 with increases in direct costs and expenses for advisors and selling, general and administrative (“SG&A”) expenses partially offset by a decrease in depreciation and amortization.  The increases in SG&A and direct costs and expenses for advisors were due primarily to higher: license expense of $3.6 million, stock compensation of $2.4 million, compensation and benefits of $2.2 million, computer expense of $1.0 million, professional fees of $1.0 million, event expense of

$0.6 million, tax indemnity receivable of $0.5 million and occupancy expense of $0.3 million.    These cost increases were partially offset primarily by lower: contract labor costs of $2.0 million, severance and integration expenses of $0.8 million, travel expense of $0.8 million, acquisition-related costs of $0.6 million and contingent consideration of $0.5 million.  

Compensation costs consist of a mix of fixed and variable salaries, annual bonuses, benefits and retirement plan contributions. Statutory and 401(k) plans are offered to employees as appropriate. Direct costs also include employee taxes, health insurance, workers compensation and disability insurance.

A portion of compensation expenses for certain billable employees are allocated between direct costs and selling, general and administrative costs based on relative time spent between billable and non‑billable activities.

Selling costs consist principally of compensation expense related to business development, proposal preparation and delivery, and negotiation of new client contracts. Selling costs also include travel expenses relating to the pursuit of sales opportunities, expenses for hosting periodic client conferences, public relations activities, participation in industry conferences, industry relations, website maintenance and business intelligence activities. Additionally, we maintain a dedicated global marketing function responsible for developing and managing sales campaigns, brand promotion, the ISG Index and assembling client proposals.

We maintain a comprehensive program for training and professional development with the related costs included in SG&A. Related expenses include product training, updates on new service offerings or methodologies and development of client project management skills. Also included in training and professional development are expenses associated with the development, enhancement and maintenance of our proprietary methodologies and tools and the systems that support them.

Selling, general and administrative expenses consist principally of executive management compensation, allocations of billable employee compensation related to general management activities, IT infrastructure, and costs for the finance, accounting, information technology and human resource functions. General and administrative costs also reflect continued investment associated with implementing and operating client and employee management systems. Because our billable personnel operate primarily on client premises, all occupancy expenses are recorded as general and administrative.

Depreciation and amortization expense in 2018 and 2017 were $7.8 million and $12.7 million, respectively.  The decrease of $4.9 million in depreciation and amortization expense was primarily due to prior year intangible assets that are now fully amortized.  Depreciation expense is generally computed by applying the straight‑line method over the estimated useful lives of assets. We also capitalize some costs associated with the purchase and development of internal‑use software, system conversions and website development costs. These costs are amortized over the estimated useful life of the software or system.

We amortize our intangible assets (e.g., client relationships and databases) over their estimated useful lives. Goodwill related to acquisitions are not amortized but are subject to annual impairment testing.

The total decrease of $0.5 million was primarily the result of a net foreign currency gain and lower interest expense attributable to our lower debt balance.

Income Tax Expense

Our effective tax rate varies from period to period based on the mix of earnings among the various state and foreign tax jurisdictions in which business is conducted and the level of non‑deductible expenses incurred in any given period.  Our effective tax rate for the year ended December 31, 2018 was 7.1% compared to 199.9% for the year ended December 31, 2017.  The variance between the US statutory rate of 21% for the year ended December 31, 2018 was primarily caused by the release of accruals for uncertain tax positions and the impact of the Tax Cuts and Jobs Act “TCJA”.

NON-GAAP FINANCIAL PRESENTATION

This management’s discussion and analysis presents supplemental measures of our performance that are derived from our consolidated financial information but are not presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We refer to these financial measures, which are considered “non-GAAP financial measures” under SEC rules, as adjusted EBITDA, adjusted net income, and adjusted earnings per diluted share, each as defined below. See “Non-GAAP Financial Measures” below for information about our use of these non-GAAP financial measures, including our reasons for including these measures and reconciliations of each non-GAAP financial measure to the most directly comparable GAAP financial measure.

NON-GAAP FINANCIAL MEASURES

We use non-GAAP financial measures to supplement the financial information presented on a GAAP basis.  We provide adjusted EBITDA (defined as net income before net income attributable to non-controlling interest, plus interest, taxes, depreciation and amortization, foreign currency transaction gains/losses, non-cash stock compensation, change in contingent consideration, acquisition-related costs, tax indemnity receivable, severance and integration expense), adjusted net income (defined as net income plus amortization of intangible assets, non-cash stock compensation, foreign currency transaction gains/losses, change in contingent consideration, acquisition-related costs, severance and integration expense, on a tax-adjusted basis) and adjusted net income as earnings per diluted share, excluding the net of tax effect of the items set forth in the table below. These are non-GAAP measures that the Company believes provide useful information to both management and

investors by excluding certain expenses and financial implications of foreign currency translations, which management believes are not indicative of ISG’s core operations. These non-GAAP measures are used by the Company to evaluate the Company’s business strategies and management’s performance.  These non-GAAP financial measures exclude non-cash and certain other special charges that many investors believe may obscure the user’s overall understanding of the Company’s current financial performance and the Company’s prospects for the future. We believe that these non-GAAP measures provide useful information to investors because they improve the comparability of the financial results between periods and provide for greater transparency of key measures used to evaluate the Company’s performance.

(1) Consists of expenses from acquisition-related costs and non-cash fair value adjustments on pre-acquisition contract liabilities.

(2) Marginal tax rate of 32% and 38% applied, respectively.

Capital Resources

The Company’s current outstanding debt, may limit our ability to fund general corporate requirements and obtain additional financing, impact our flexibility in responding to business opportunities and competitive developments and increase our vulnerability to adverse economic and industry conditions.

On December 1, 2016, the Company amended and restated its senior secured credit facility to include a $110.0 million term facility and a $30.0 million revolving facility (the “2016 Credit Agreement”).  The material terms under the 2016 Credit Agreement are as follows:

 Each of the term loan facility and revolving credit facility has a maturity date of December 1, 2021 (the “Maturity Date”).

 The credit facility is secured by all of the equity interests owned by the Company, and its direct and indirect domestic subsidiaries and, subject to agreed exceptions, the Company’s direct and indirect “first-tier” foreign subsidiaries and a perfected first priority security interest in all of the Company’s and its direct and indirect domestic subsidiaries’ tangible and intangible assets.

 The Company’s direct and indirect existing and future wholly-owned domestic subsidiaries serve as guarantors to the Company’s obligations under the senior secured facility.

 At the Company’s option, the credit facility bears interest at a rate per annum equal to either (i) the “Base Rate” (which is the highest of (a) the rate publicly announced from time to time by the administrative agent as its “prime rate”, (b) the Federal Funds Rate plus 0.5% per annum and (c) the Eurodollar Rate, plus 1.0%), plus the applicable margin (as defined below) or (ii) Eurodollar Rate (adjusted for maximum reserves) as determined by the Administrative Agent, plus the applicable margin.  The applicable margin is adjusted quarterly based upon the Company’s quarterly leverage ratio. 

 The Term Loan is repayable in four consecutive quarterly installments of $1,375,000 each, that commenced March 31, 2017, followed by eight consecutive quarterly installments in the amount of $2,062,500 each, that commenced March 31, 2018, followed by seven consecutive quarterly installments of $2,750,000 each, commencing March 31, 2020 and a final payment of the outstanding principal amount of the Term Loan on the Maturity Date.

 Mandatory repayments of term loans shall be required from (subject to agreed exceptions) (i) 100% of the proceeds from asset sales by the Company and its subsidiaries, (ii) 100% of the net proceeds from issuances of debt and equity by the Company and its subsidiaries and (iii) 100% of the net proceeds from insurance recovery and condemnation events of the Company and its subsidiaries.

 The senior secured credit facility contains a number of covenants that, among other things, place restrictions on matters customarily restricted in senior secured credit facilities, including restrictions on indebtedness (including guarantee obligations), liens, fundamental changes, sales or disposition of property or assets, investments (including loans, advances, guarantees and acquisitions), transactions with affiliates, dividends and other payments in respect of capital stock, optional payments and modifications of other material debt instruments, negative pledges and agreements restricting subsidiary distributions and changes in line of business. In addition, the Company is required to comply with a total leverage ratio and fixed charge coverage ratio.

 The senior secured credit facility contains customary events of default, including cross-default to other material agreements, judgment default and change of control.

On February 10, 2017, as required by the 2016 Credit Agreement, the Company entered into an agreement to cap the interest rate at 4% on the LIBOR component of its borrowings under the term loan facility until December 31, 2019. This interest rate cap was not designated for hedging or speculative purposes. The expense related to this interest rate cap was not material.

As of December 31, 2018, the total principal outstanding under the term loan facility and revolving credit facility was $95.1 million and $4.0 million, respectively. The effective interest rate for the term loan facility and revolving credit facility as of December 31, 2018 was 5.5% and 5.3%, respectively.

On December 1, 2016, as part of the merger consideration for the acquisition of Alsbridge, we issued an aggregate of $7.0 million in unsecured subordinated promissory notes (the “Alsbridge Notes”). The Alsbridge Notes accrued interest on the principal amount daily at a rate of 2.0%. At maturity, on September 4, 2018, we paid off the full $7.0 million of principal and $0.2 million of interest outstanding under the Alsbridge Notes.

We anticipate that our current cash and the ongoing cash flows from our operations will be adequate to meet our working capital and capital expenditure needs for at least the next twelve months. The anticipated cash needs of our business could change significantly if we pursue and complete additional business acquisitions, if our business plans change, if economic conditions change from those currently prevailing or from those now anticipated, or if other unexpected circumstances arise that may have a material effect on the cash flow or profitability of our business. If we require additional capital resources to grow our business, either internally or through acquisition, we may seek to sell additional equity securities or to secure debt financing. The sale of additional equity securities or certain forms of debt financing could result in additional dilution to our stockholders. We may not be able to obtain financing arrangements in amounts or on terms acceptable to us in the future.

We believe that cash flows generated from operations, existing cash and cash equivalents and borrowing capacity under our senior secured credit facility are sufficient to finance the requirements of our business during future periods.

Off‑Balance Sheet Arrangements

We do not have any off‑balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets or any obligation arising out of a material variable interest in an unconsolidated entity.

Employee Retirement Plans

For the fiscal years ended December 31, 2018 and 2017, we contributed $2.4 million and $1.5 million, respectively, to the 401(k) plan (the “Savings Plan”). These amounts were invested by the participants in a variety of investment options under an arrangement with a third party asset manager. All current and future financial risks associated with the gains and losses on investments are borne by Savings Plan participants.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires the appropriate application of certain accounting policies, many of which require management to make estimates and assumptions about future events and their impact on amounts reported in our consolidated financial statements and related notes. Since future events and their impact cannot be determined with certainty, the actual results may differ from estimates. Such differences may be material to the consolidated financial statements.

We believe the application of accounting policies, and the estimates inherently required therein, are reasonable. These accounting policies and estimates are periodically reevaluated, and adjustments are made when facts and circumstances dictate a change. Historically, we have found the application of accounting policies to be appropriate, and actual results have not differed materially from those determined using necessary estimates.

Our accounting policies are more fully described in Note 2 “Summary of Significant Accounting Policies” in the “Notes to the Consolidated Financial Statements.” We have identified the following critical accounting estimates:

Revenue Recognition

We recognize our revenues for the sale of services and products by applying the following five steps: (1) identify the contract with the customer; (2) identify the performance obligation(s) in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligation(s); and (5) recognize revenue when (or as) the company satisfies the performance obligations.

We principally derive revenues from fees for services generated on a project‑by‑project basis. Prior to the commencement of a project, we reach agreement with the client on rates for services based upon the scope of the project, staffing requirements and the level of client involvement. It is our policy to obtain written agreements from clients prior to performing services. In these agreements, the clients acknowledge that they will pay based upon the amount of time spent on the project or an agreed upon fee structure. In instances where substantive acceptance provisions are specified in customer contracts, revenues are deferred until all acceptance criteria have been met.

Revenues for time and materials contracts are recognized based on the number of hours worked by our advisors at an agreed upon rate per hour and are recognized in the period in which services are performed.

Revenues for time and materials contracts are billed monthly, semimonthly or in accordance with the specific contractual terms of each project.

Revenues related to fixed fee or capped fee contracts are recognized into revenue as value is delivered to the customer, consistent with the transfer of control to the customer over time. Revenue for these contracts is recognized proportionally over the term of the contract using an input method based on the proportion of labor hours incurred as compared to the total estimated labor hours for the project, which we consider the best available indicator of the pattern and timing in which contract obligations are fulfilled and control transfers to the customer. This percentage is multiplied by the contracted dollar amount of the project to determine the amount of revenue to recognize in an accounting period. The contracted amount used in this calculation typically excludes the amount the client pays for reimbursable expenses. There are situations where the number of hours to complete projects may exceed our original estimate as a result of an increase in project scope or unforeseen events. On a regular basis, we review the hours incurred and estimated total labor hours to complete. The results of any revisions in these estimates are reflected in the period in which they become known.

The agreements entered into in connection with a project, whether on a time and materials basis or fixed fee or capped fee basis, typically allow our clients to terminate early due to breach or for convenience with 30 days’ notice. In the event of termination, the client is contractually required to pay for all time, materials and expenses incurred by us through the effective date of the termination.  For managed service implementation contracts, revenue is recognized over time as a percentage of hours incurred to date as compared to the total expected hours of the implementation, consistent with the transfer of control to the customer.  In addition, from time to time, we enter into agreements with clients that limit our right to enter into business relationships with specific competitors of that client for a specific time period. These provisions typically prohibit us from performing a defined range of services that it might otherwise be willing to perform for potential clients. These provisions are generally limited to six to twelve months and usually apply only to specific employees or the specific project team.

We also derive revenues based on negotiating reductions in network costs of companies with the entity’s related service providers and providing other services such as audits of network and communication expenses, and consultation for network architecture.  These contracts can be fixed in fees or can be based on the level of savings achieved related to its communications costs.  Additionally, these contracts can also have a fixed component and a contingent component that is based on the savings generated by the Company.  For network contingency contracts with termination for convenience clauses, revenue is recognized over time due to the existence of provisions for payment for progress incurred to date plus a reasonable profit margin.  The contract periods range from a few months to in excess of a year.

We also enter into arrangements for the sale of robotics software licenses and related delivery of consulting services at the same time or within close proximity to one another. Such software-related performance obligations include the sale of software licenses and other software-related services.  For software and implementation contracts, revenue associated with the software performance obligation is recognized at the point at which the software is installed, while revenue on the implementation service performance obligation is recognized over the software implementation period as a percentage of hours incurred to date as compared to the total expected hours.

When we recognize revenues in advance of billing, those revenues are recorded as contract assets.  When we receive cash in advance of completing services or earning revenues, those amounts are recorded as contract liabilities.

Accounts Receivable, Contract Assets and Allowance for Doubtful Accounts

Our trade receivables primarily consist of amounts due for services already performed via fixed fee or time and materials arrangements. We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of clients to pay fees or for disputes that affect its ability to fully collect billed accounts receivable. The allowance for these risks is prepared by reviewing the status of all accounts and recording reserves on a specific identification method based on previous experiences and historical bad debts. However, our actual experience may vary significantly from these estimates. If the financial condition of our clients were to deteriorate, resulting in their inability or unwillingness to pay their invoices, we may need to record additional allowances or write‑offs in future periods. To the extent the provision relates to a client’s inability or unwillingness to make required payments, the provision is recorded as bad debt expense, which is classified within selling, general and administrative expense in the accompanying consolidated statement of comprehensive income.

The provision for unbilled services is recorded as a reduction to revenues to the extent the provision relates to fee adjustments and other discretionary pricing adjustments.

Income Taxes

We use the asset and liability method to account for income taxes, including recognition of deferred tax assets and liabilities for the anticipated future tax consequences attributable to differences between financial statement amounts and their respective tax basis. We review our deferred tax assets for recovery. A valuation allowance is established when we believe that it is more likely than not that some portion of its deferred tax assets will not be realized. Changes in the valuation allowance from period to period are included in our tax provision in the period of change.

For uncertain tax positions, we use the prescribed model for assessing the financial recognition and measurement of all tax positions taken or expected to be taken in tax returns. This guidance provides clarification on derecognition, classification, interest and penalties, accounting in interim periods, disclosures and transition. Our provision for income taxes also includes the impact of provisions established for uncertain income tax positions, as well as the related interest.

In December 2017, the Tax Cuts and Jobs Act (the “TCJ Act”) legislation was enacted. The TCJ Act includes significant changes to the U.S. corporate tax system, including a U.S. federal corporate income tax rate reduction from 35% to 21% and other changes. Accounting Standards Codification 740, Income Taxes, requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation was enacted. However, with respect to the TCJ Act, given the significance of the change and the time of year in which it was enacted, guidance was provided that enabled companies to recognize the impacts on a provisional basis.  As such, we have accounted for the tax effects as a result of the enactment of the TCJ Act as of December 31, 2017 on a provisional basis and have updated our provisional assessment of the tax effects of the TCJ Act during the year ended December 31, 2018.

Goodwill

Our goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired at the date of acquisition. Goodwill is not amortized but rather tested for impairment at least annually in accordance with accounting and disclosure requirements for goodwill and other indefinite‑lived intangible

assets. This test is performed by us during our fourth fiscal quarter or more frequently if we believe impairment indicators are present.

A qualitative assessment is performed to determine whether the existence of events or circumstances leads to a determination that it is more likely than not the fair value of the reporting unit is less than its carrying amount. If, based on the evaluation, it is determined to be more likely than not that the fair value is less than the carrying value, then goodwill is tested further for impairment. If the implied fair value of goodwill is lower than their carrying amounts, an impairment loss is recognized in an amount equal to the difference. Subsequent increases in value are not recognized in the financial statements.

The Company adopted Accounting Standards Update (“ASU”) 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" effective December 30, 2017 which has eliminated Step 2 from the goodwill impairment test. Under this update, if an impairment is identified, an entity should record the goodwill impairment as an amount resulting from the comparison of the fair value of a reporting unit with its carrying amount.

There was no impairment of goodwill during the years ended December 31, 2018 and 2017, nor were any indicators identified in 2017 or 2018 that would suggest that it is more likely than not that the Company’s reporting unit is impaired.

Long‑Lived Assets

Long lived assets, excluding goodwill and indefinite lived intangibles, to be held and used by the Company are reviewed to determine whether any significant change in the long-lived asset’s physical condition, a change in industry conditions or a reduction in cash flows associated with the use of the long-lived asset. If these or other factors indicate the carrying amount of the asset may not be recoverable, the Company determines whether impairment has occurred through the use of an undiscounted cash flow analysis at the asset group level, which is the lowest level for which identifiable cash flows exist that are separately identifiable from other cash flows. If impairment has occurred, the Company recognizes a loss for the difference between the carrying amount and the fair value of the asset group. The fair value of the asset group is measured using market prices or, in the absence of market prices, an estimate of discounted cash flows. Cash flows are generally discounted at an interest rate commensurate with our weighted average cost of capital. Assets are classified as held for sale when the Company has a plan for disposal of certain assets and those assets meet the held for sale criteria.

Stock‑Based Compensation

We grant restricted stock units with a fair value that is determined based on the closing price of our common stock on the date of grant.  Such grants generally vest ratably over a four‑year period for employees and a three-year period for directors. Stock‑based compensation expense is recognized ratably over the applicable service period.

We follow the provisions of accounting and disclosure requirements for share‑based payments, including the measurement and recognition of all share‑based compensation under the fair value method.

Recent Accounting Pronouncements

See Note 2 to our consolidated financial statements included elsewhere in this report.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2018, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on the Effectiveness of Controls

Our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud.  A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.  Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.  Because of the inherent limitations in a cost-effective control system, no controls can provide absolute assurance that misstatements due to error or fraud will not occur, and no evaluation of any such controls can provide absolute assurance that control issues and instances of fraud, if any, within our Company have been detected.

These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake.  Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls.  The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.  Projections of any evaluation of controls’ effectiveness to future periods are subject to risks.  Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies and procedures.
