PART I

Overview

CSG Systems International, Inc. (the “Company”, “CSG”, or forms of the pronoun “we”) is one of the world’s largest and most established business support solutions providers primarily serving the communications industry. Our proven approach and solutions are based on our broad and deep experience in serving clients in the communications industry as their businesses have evolved from a single product offering to a highly complex, highly competitive, multi-product service offering. Our approach has centered on using the best technology for the various functions required to provide world-class solutions.

Our solutions help service providers streamline and scale operations, introduce and adapt products and services to meet changing consumer demands, and address the challenges and opportunities of a dynamically evolving global business environment. Our broad suite of solutions helps our clients improve their business operations by creating more compelling product offerings and an enhanced customer experience through more relevant and targeted interactions, while at the same time, more efficiently managing the service provider’s cost structure. Over the years, we have focused our research and development (“R&D”) and acquisition investments on expanding our solution set to address the ever expanding needs of communications service providers to provide a differentiated, real-time, and personal experience for their consumers. This extensive suite of solutions includes revenue management, content management and monetization, and customer interaction management platforms.

Our principal executive offices are located at 9555 Maroon Circle, Englewood, Colorado 80112, and the telephone number at that address is (303) 200-2000. Our common stock is listed on the NASDAQ Stock Market LLC (“NASDAQ”) under the symbol “CSGS”. We are a S&P Small Cap 600 company.

Industry Overview

Background. We provide business support solutions (BSS) to the world’s leading communications service providers, as well as clients in several evolving, highly competitive industries. Our solutions coordinate and manage many aspects of a service provider’s customer interactions, from the initial activation of customer accounts, to the support and fulfilment of various products and services, and through the presentment, collection, and accounts receivables management of monthly customer statements. While our heritage is in serving the North American video and satellite market, through acquisition and organic growth, we have broadened and enhanced our solutions to extend our business both globally and to a number of other industries including content distribution, media and entertainment, and telecommunications.

Market Conditions of the Communications Industry. As the majority of our clients operate within the global communications industry sector, the economic state of this industry directly impacts our business.  The global communications industry has undergone significant fluctuations in growth rates and capital investment cycles over the past several years due to multiple competitive and economic factors.  Current economic indices suggest a slow stabilization of the industry, but it is impossible to predict whether this stabilization will persist or be subject to future instability.  In addition, industry consolidation continues as service providers look for ways to expand their markets, increase their revenues, and gain greater scale efficiencies in their operations.

The impact of these market factors has resulted in spending cautiousness with large transformational projects being displaced in favor of more incremental changes to business operations. Globally, mature operators are looking for ways to control costs, streamline operations, roll out new products and services quickly, and expand their scale, while operators in emerging markets are focusing on capitalizing on the growth of new services and the explosion of connected devices. Regardless of the specific situation, companies continue to have an increased focus on investing in those solutions and services that have a demonstrable short-term return on investment, generate new revenues, and help businesses remain competitive and meet rapidly changing consumer demands.

Market Trends of Communications Industry. The communications industry is experiencing heightened competition and a dramatic shift in purchasing power to the consumer as the consumer now has more choices for content, devices, and providers than ever before. There are three key trends that are emerging as communication service providers (“CSPs”) try to evolve and compete in this highly complex ecosystem.

3

Overall, these market trends drive the demand for scalable, flexible, and cost-efficient revenue management and customer interaction management solutions, which we believe will provide us with revenue opportunities. As a result, we have historically invested a significant amount of our revenues in R&D and have acquired companies that enable us to expand our offerings in a more timely and efficient manner. We believe that our scalable, modular, and flexible solutions combined with our rich domain expertise provide the industry with proven solutions to improve their profitability and consumers’ experiences.  We have specifically architected our solutions to provide operators with a more incremental approach to transforming their businesses, thereby reducing the risk associated with this evolution.

Business Strategy

Our goal is to be the most trusted provider of world-class software and services to service providers around the world who depend upon the timely and accurate processing of complex, high-volume transactions to operate their business and deliver a superior customer experience. We believe that by successfully executing on this goal we can grow our revenues and earnings, and therefore, create long-term value, not only for our clients and our employees, but for our stockholders as well. Our strategic focus to accomplish this goal is as follows:

Create Long-Term, Recurring Relationships Within The Communications Industry. Our relentless, relationship-driven, customer-focused business approach is built on a foundation of respect, integrity, and collaboration. As a result, we enjoy long-term relationships with many of the world’s leading service providers based on a true partnership aimed at helping providers enable sustainable growth, create efficiencies, and deliver differentiated services to their customers.

Expand Our Product and Services Portfolio Through Continuous Innovation. We believe that our product technology and pre-integrated suite of software solutions gives service providers a competitive advantage. We continually add new, relevant capabilities to what we do as a company, both in terms of our people and our solutions. By doing this, we build very strong recurring relationships which are difficult for our competitors to displace.

Increase Our Value Proposition Through Continuous Improvement. As discussed earlier, the demands of consumers are significantly increasing as devices and networks continue to feed an insatiable appetite for content, information, and entertainment. In order to continue to help providers better compete in an environment in which network consumption is outpacing revenue generation, we continue to focus on being cost efficient in delivering our solutions, while helping our clients efficiently and effectively manage their business.

Deliver On Our Commitments. Our products and services are business critical. We help our clients manage the entire customer lifecycle, from acquisition to servicing to billing for their end customers. As a result, it is imperative that we deliver on our commitments. For over 30 years, we have been helping blue-chip companies manage periods of explosive and sustained market growth and change – helping them drive revenues, improve their profitability, and deliver positive customer experiences. Our track record of doing what we say we are going to do has enabled us to become embedded in our clients’ operations and be a trusted advisor and integral member of their teams.

4

Bring New Skills and Talents to Market. In order to help our clients manage the pace of change, we invest in our people so that they are prepared to bring the highest quality technical skills, interpersonal skills, and managerial skills to our business and our clients.

In summary, we are focused on helping our clients compete more effectively and successfully in an ever-changing market.

Description of Business

Key Clients. We work with the leading communication providers located around the world. A partial list of those service providers as of December 31, 2015 is included below:

The North American communications industry has experienced significant consolidation over the past decade, resulting in a large percentage of the market being served by a limited number of service providers with greater size and scale, and there are possibilities of further consolidation, illustrated by the current proposed acquisition of Time Warner by Charter, which is currently our fourth largest client. Consistent with this market concentration and our heritage in serving the North American cable and satellite markets, a large percentage of our historical revenues have been generated from our three largest clients, as shown in the table below. Clients that represented 10% or more of our revenues for 2015 and 2014 were as follows (in millions, except percentages):

See the Significant Client Relationships section of our MD&A for additional information regarding our business relationships with these key clients.

Research and Development. Our clients around the world are facing competition from new entrants and at the same time, are deploying new services at a rapid pace and dramatically increasing the complexity of their business operations. Therefore, we continue to make meaningful investments in R&D to ensure that we stay ahead of our clients’ needs and advance our clients’ businesses as well as our own. We recognize these challenges and believe our value proposition is to provide solutions that help our clients ensure that each customer interaction is an opportunity to create value and deepen the business relationship. As a result of our R&D efforts, we have not only broadened our footprint within our client base with many new innovative product offerings, but have also found success in penetrating new markets with portions of our suite of customer interaction management solutions.

Our total R&D expenses for 2015 and 2014 were $102.0 million and $104.7 million, respectively, or approximately 14% of our total revenues. In the near term, we expect that our R&D investment activities will be relatively consistent with that of 2015, with the level of our total R&D spend highly dependent upon the opportunities that we see in our markets.

There are certain inherent risks associated with significant technological innovations. Some of these risks are described in this report in our Risk Factors section below.

Products and Services. Our products and services help companies with complex transaction-centric business models manage the opportunities and challenges associated with accurately capturing, managing, generating, and optimizing the revenue associated with the immense volumes of customer interactions and then manage the intricate nature of those customer relationships. Our primary product solutions include the following:

5

Customer Interaction Management: Our customer interaction management solutions help deliver a unique, personal and relevant quality experience across all customer touch points – whether that is text, e-mail, web, print, or other communications methods. We are an industry leader in interaction management solutions, processing more than one billion interactive voice, SMS/text, print, e-mail, web, and fax messages each year on behalf of our clients.  In summary, we offer a fully integrated, cloud-based revenue and customer management solution, complemented with world-class applications software and customized software solutions, allowing us to provide one of the most comprehensive, flexible, pre-integrated products and services solutions to the communications market. We believe this pre-integrated approach and multiple delivery models allows our clients to bring new product offerings to market quickly and provide high-quality customer service in a cost effective manner. In addition, we also license certain software products (e.g., Singleview, TSM, and WBMS) and provide expert professional services to implement, configure, and maintain these software products.

Historically, a substantial percentage of our total revenues have been generated from ACP and Customer Interaction Management solutions. These products and services are expected to provide a large percentage of our total revenues in the foreseeable future as well.

Business Acquisitions. As noted above, our strategy includes acquiring assets and businesses which provide the technology and technical personnel to expedite our product development efforts, provide complementary products and services, increase market share, and/or provide access to new markets and clients.

Professional Services. We employ professional services experts globally who bring a wide-ranging expertise – including solution architecture, project management, systems implementation, and business consultancy – to every project. We apply a methodology to each of our engagements, leveraging consistent world-class processes, best-practice programs, and systemized templates for all engagements.

Managed Services. We expanded our managed services capabilities and expertise developed in our North American operations to international operators in early 2013. For our managed services clients, we assume long-term responsibility for delivering our software solutions and related operations under a defined scope and specified service levels, generally using our clients’ infrastructure and premises.

Client and Product Support. Our clients typically rely on us for ongoing support and training needs related to our products. We have a multi-level support environment for our clients, which include account management teams to support the business, operational, and functional requirements of each client. These account teams help clients resolve strategic and business issues and are supported by our International Service Desk (“ISD”) and Global Operations Service Management (“GOSM”), which we operate 24 hours a day, seven days a week. Clients call a telephone number, and through an automated voice response unit, have their calls directed to the

6

appropriate ISD or GOSM personnel to answer their questions. We have a full-time training staff and conduct ongoing training sessions both in the field and at our training facilities.

Sales and Marketing. We organize our sales efforts to clients primarily within our geographically dispersed, dedicated account teams, with senior level account managers who are responsible for new revenues and renewal of existing contracts within a client account. The account teams are supported by sales support personnel who are experienced in the various products and services that we provide.

Competition. The market for business support solutions products and services in the communications industry, as well as in other industries we serve, is highly competitive. We compete with both independent providers and in-house developers of customer management systems. We believe that our most significant competitors in our primary markets are Amdocs Limited, NEC Corporation, and Oracle Corporation; network equipment providers such as Ericsson, Huawei, and Alcatel-Lucent; and internally-developed solutions. Some of our actual and potential competitors have substantially greater financial, marketing, and technological resources than us and in some instances we may actually partner and collaborate with our competitors on large opportunities and projects.

We believe service providers in our industry use the following criteria when selecting a vendor to provide customer care and billing products and services: (i) functionality, scalability, flexibility, interoperability, and architecture of the software assets; (ii) the breadth and depth of pre-integrated product solutions; (iii) product quality, client service, and support; (iv) operational excellence and reliability; (v) quality of R&D efforts; and (vi) price. We believe that our products and services allow us to compete effectively in these areas.

Proprietary Rights and Licenses

We rely on a combination of trade secret, copyright, trademark, and patent laws in the United States (“U.S.”) and similar laws in other countries, and non-disclosure, confidentiality, and other types of contractual arrangements to establish, maintain, and enforce our intellectual property rights in our solutions. Despite these measures, any of our intellectual property rights could be challenged, invalidated, circumvented, or misappropriated. Although we hold a limited number of patents and patent applications on some of our newer solutions, we do not rely upon patents as a primary means of protecting our rights in our intellectual property. In any event, there can be no assurance that our patent applications will be approved, that any issued patents will adequately protect our intellectual property, or that such patents will not be challenged by third parties. Also, much of our business and many of our solutions rely on key technologies developed or licensed by third parties, and we may not be able to obtain or continue to obtain licenses and technologies from these third parties at all or on reasonable terms. Our failure to adequately establish, maintain, and protect our intellectual property rights could have a material adverse impact on our business, financial condition, and results of operations. For a description of the risks associated with our intellectual property rights, see “Item 1A - Risk Factors - Failure to Protect Our Intellectual Property Rights or Claims by Others That We Infringe Their Intellectual Property Rights Could Substantially Harm Our Business, Financial Condition and Results of Operations.”

Employees

As of December 31, 2015, we had a total of 3,277 employees, a decrease of 171 employees when compared to the number of employees we had as of December 31, 2014. Our success is dependent upon our ability to attract and retain qualified employees. None of our employees are subject to a collective bargaining agreement, but are subject to various foreign employment laws and regulations based on the country in which they are employed. We believe that our relations with our employees are good.

Available Information

Our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, proxy materials, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act are available free of charge on our website at www.csgi.com. Additionally, these reports are available at the SEC’s Public Reference Room at 100 F Street, NE., Washington, D.C. 20549 or on the SEC’s website at www.sec.gov. Information on the operation of the Public Reference Room can be obtained by calling the SEC at 1-800-SEC-0330.

Code of Business Conduct and Ethics

A copy of our Code of Business Conduct and Ethics (the “Code of Conduct”) is maintained on our website. Any future amendments to the Code of Conduct, or any future waiver of a provision of our Code of Conduct, will be timely posted to our website upon their occurrence. Historically, we have had minimal changes to our Code of Conduct, and have had no waivers of a provision of our Code of Conduct.

We or our representatives from time-to-time may make or may have made certain forward-looking statements, whether orally or in writing, including without limitation, any such statements made or to be made in MD&A contained in our various SEC filings or orally in conferences or teleconferences. We wish to ensure that such statements are accompanied by meaningful cautionary statements, so as to ensure, to the fullest extent possible, the protections of the safe harbor established in the Private Securities Litigation Reform Act of 1995.

Accordingly, the forward-looking statements are qualified in their entirety by reference to and are accompanied by the following meaningful cautionary statements identifying certain important risk factors that could cause actual results to differ materially from those in such forward-looking statements. This list of risk factors is likely not exhaustive. We operate in rapidly changing and evolving markets throughout the world addressing the complex needs of communication service providers, financial institutions, and many others, and new risk factors will likely emerge. Further, as we enter new market sectors such as financial services, as well as new geographic markets, we are subject to new regulatory requirements that increase the risk of non-compliance and the potential for economic harm to us and our clients. Management cannot predict all of the important risk factors, nor can it assess the impact, if any, of such risk factors on our business or the extent to which any risk factor, or combination of risk factors, may cause actual results to differ materially from those in any forward-looking statements. Accordingly, there can be no assurance that forward-looking statements will be accurate indicators of future actual results, and it is likely that actual results will differ from results projected in forward-looking statements and that such differences may be material.

We Derive a Significant Portion of Our Revenues From a Limited Number of Clients, and the Loss of the Business of a Significant Client Could Have a Material Adverse Effect on Our Financial Position and Results of Operations.

Over the past decade, the worldwide communications industry has experienced significant consolidation, resulting in a large percentage of the market being served by a limited number of service providers with greater size and scale, and there are possibilities of further consolidation. Consistent with this market concentration, we generate approximately 50% of our revenues from our three largest clients, which are (in order of size) Comcast, DISH, and Time Warner, which each individually accounted for 10% or more of our total revenues. See the Significant Client Relationships section of MD&A for key renewal dates and a brief summary of our business relationship with these clients.

There are inherent risks whenever a large percentage of total revenues are concentrated with a limited number of clients. One such risk is that a significant client could: (i) undergo a formalized process to evaluate alternative providers for services we provide; (ii) terminate or fail to renew their contracts with us, in whole or in part for any reason; (iii) significantly reduce the number of customer accounts processed on our solutions, the price paid for our services, or the scope of services that we provide; or (iv) experience significant financial or operating difficulties. Any such development could have a material adverse effect on our financial position and results of operations and/or trading price of our common stock.

Our industry is highly competitive, and as a result, it is possible that a competitor could increase its footprint and share of customers processed at our expense or a provider could develop their own internal solutions. While our clients may incur some costs in switching to our competitors or their own internally-developed solutions, they may do so for a variety of reasons, including: (i) price; (ii) if we do not provide satisfactory solutions or service levels; or (iii) if we do not maintain favorable relationships.

We May Not Realize Our Anticipated Growth With Comcast Related to New Customer Account Migration Opportunities.

In July 2014, we entered into an expanded and extended contract with our largest client, Comcast.  The expanded contract provides the framework for Comcast to consolidate its residential business onto our billing solution.  Under the new agreement, Comcast added approximately two million residential customers onto our billing solution in late 2014 and approximately two million more in 2015.  We believe we have the opportunity to migrate up to an additional six million Comcast customer accounts that are currently on one of our competitor’s platforms onto our solution over the next several years as part of Comcast’s future standardization initiatives for their residential business.

Although Comcast has expressed to us their intention to consolidate their residential customer accounts to our platform, they have no financial or legal requirement to do so.  The timing of and the number of customer accounts to be migrated to CSG, if any, is at the discretion of Comcast.  There can be no assurances, therefore, as to the timing or the number of any new customer accounts migrated to us by Comcast.

8

We May Not Be Able to Efficiently and Effectively Implement New Solutions or Convert Clients onto Our Solutions.

Our continued growth plans include the implementation of new solutions, as well as migrating both new and existing clients to our solutions. Such implementations or migrations (collectively referred to hereafter in this section as “implementations”), regardless of whether they involve new solutions or new customers, have become increasingly more difficult because of the sophistication, complexity, and interdependencies of the various software  and network environments impacted, combined with the increasing complexity of the clients’ underlying business processes. In addition, the complexity of the implementations increases when the arrangement includes other vendors participating in the project, including but not limited to, prime and subcontractor relationships with our company. For these reasons, implementations subject our clients’ to potential business disruption, which could cause them to delay or even cancel future implementations.  

As a result, there is a risk that we may experience cancellations of previously scheduled implementations, delays in an implementation, or unexpected costs associated with particular implementations. In addition, our inability to complete implementations in an efficient and effective manner could have a material adverse effect on our results of operations, and could damage our reputation in the market place, reducing our opportunity to grow our business with both new and existing clients.

The Delivery of Our Solutions is Dependent on a Variety of Computing Environments and Communications Networks Which May Not Be Available or May Be Subject to Security Attacks.

Our processing solutions are generally delivered through a variety of computing environments operated by us (collectively referred to hereafter in this section as “Systems”). We provide such computing environments through both outsourced arrangements, such as our current data processing arrangement with Infocrossing LLC (“Infocrossing”), a Wipro Limited company, as well as internally operating numerous distributed servers in geographically dispersed environments. The end users are connected to our Systems through a variety of public and private communications networks, which we will collectively refer to herein as “Networks.” Our solutions are generally considered to be mission critical customer management systems by our clients. As a result, our clients are highly dependent upon the high availability and uncompromised security of our Networks and Systems to conduct their business operations.

Our Networks and Systems are subject to the risk of an extended interruption, outage, or security breach due to many factors such as: (i) planned changes to our Systems and Networks for such things as scheduled maintenance and technology upgrades, or migrations to other technologies, service providers, or physical location of hardware; (ii) human and machine error; (iii) acts of nature; and (iv) intentional, unauthorized attacks from computer “hackers”, or cyber-attacks. Most recently, the marketplace is experiencing an ever-increasing exposure to both the number and severity of cyber-attacks.  In addition, we continue to expand our use of the Internet with our product offerings thereby permitting, for example, our clients’ customers to use the Internet to review account balances, order services or execute similar account management functions. Allowing access to our Networks and Systems via the Internet has the potential to increase their vulnerability to unauthorized access and corruption, as well as increasing the dependency of our Systems’ reliability on the availability and performance of the Internet and end users’ infrastructure they obtain through other third party providers.

The method, manner, cause and timing of an extended interruption, outage, or security breach in our Networks or Systems are impossible to predict. As a result, there can be no assurances that our Networks and Systems will not fail, not suffer a security breach or that our business continuity or remediation plans will adequately mitigate the negative effects of a disruption or security breach to our Networks or Systems. Further, our property and business interruption insurance may not adequately compensate us for losses that we incur as a result of such interruptions or security breaches. Should our Networks or Systems: (i) experience an extended interruption or outage; (ii) have their security breached; or (iii) have their data lost, corrupted or otherwise compromised, it would impede our ability to meet product and service delivery obligations, and likely have an immediate impact to the business operations of our clients. This would most likely result in an immediate loss to us of revenue or increase in expense, as well as damaging our reputation. The loss of confidential information could result in losing the customers’ confidence, as well as imposition of fines and damages. Any of these events could have an immediate, negative impact upon our financial position and our short-term revenue and profit expectations, as well as our long-term ability to attract and retain new clients.

The Occurrence or Perception of a Security Breach or Disclosure of Confidential Personally Identifiable Information Could Harm Our Business.

In providing solutions to our clients, we process, transmit, and store confidential and personally identifiable information (“PII”), including social security numbers and financial information. Our treatment of such information is subject to contractual restrictions and federal, state, and foreign data privacy laws and regulations, which continue to evolve resulting in greater scrutiny over the protection of PII. In response to these evolving restrictions and regulations, we leverage various data encryption strategies and have implemented measures to protect against unauthorized access to such information, and comply with these laws and regulations. These measures include standard industry practices (i.e. ISO-27002 guidelines), periodic security reviews of our systems by independent parties, network firewalls, procedural controls, intrusion detection systems, and antivirus applications. Because of the inherent risks and complexities to defend against cybercrime, these measures may fail to adequately protect this information. Any failure on our part

9

to protect the privacy of personally identifiable information or comply with data privacy laws and regulations may subject us to contractual liability and damages, loss of business, damages from individual claimants, fines, penalties, criminal prosecution, and unfavorable publicity. Even the mere perception of a security breach or inadvertent disclosure of personally identifiable information could damage our reputation and inhibit market acceptance of our solutions. In addition, third party vendors that we engage to perform services for us may unintentionally release personally identifiable information or otherwise fail to comply with applicable laws and regulations. The occurrence of any of these events could have an adverse effect on our business, financial position, and results of operations.

Our Business is Dependent Upon the Economic and Market Condition of the Global Communications Industry.

Since the majority of our clients operate within the global communications industry sector, the economic state of this industry directly impacts our business. The global communications industry has undergone significant fluctuations in growth rates and capital investment cycles in the past decade. Current economic indices suggest a slow stabilization of the industry, but it is impossible to predict whether this stabilization will persist or be subject to future instability. In addition, industry consolidation continues as service providers look for ways to expand their markets and increase their revenues.  A byproduct of this consolidation is that there could be fewer providers in the market, each with potentially greater bargaining power and economic leverage due to their larger size, which may result in our having to lower our prices to remain competitive, retain our market share, or comply with the surviving client’s current more favorable contract terms.

Continued consolidation, a significant retrenchment in investment by communications providers, or even a material slowing in growth (whether caused by economic, geo-political, competitive, or consolidation factors) could cause delays, cancellations or downward pricing pressure on our sales and services. This could cause us to either fall short of revenue expectations or have a cost model that is misaligned with revenues, either or both of which could have a material adverse effect on our financial position and results of operations.  

We expect to continue to generate a significant portion of our future revenues from our North American cable and satellite operators. These clients operate in a highly competitive environment. Competitors range from traditional wireline and wireless providers to new entrants like new digital lifestyle service providers such as Hulu, YouTube, Google, Netflix, Apple, and Amazon. Should these competitors be successful in their strategies, it could threaten our clients’ market share, and thus our source of revenues, as generally speaking these companies do not use our core solutions and there can be no assurance that new entrants will become our clients. In addition, demand for spectrum, network bandwidth and content continues to increase and any changes in the regulatory environment could have a significant impact to not only our clients’ businesses, but in our ability to help our clients be successful.

We May Not Be Able to Respond to Rapid Technological Changes.

The market for business support solutions, such as customer care and billing solutions, is characterized by rapid changes in technology and is highly competitive with respect to the need for timely product innovations and new product introductions. As a result, we believe that our future success in sustaining and growing our revenues depends upon: (i) our ability to continuously expand, adapt, modify, maintain, and operate our solutions to address the increasingly complex and evolving needs of our clients without sacrificing the reliability or quality of the solutions; (ii) the integration of acquired technologies and their widely distributed, complex worldwide operations; and (iii) creating and maintaining an integrated suite of customer care and billing solutions, which are portable to new verticals such as utilities, financial services, and content distribution.  In addition, the market is demanding that our solutions have greater architectural flexibility and interoperability, and that we are able to meet the demands for technological advancements to our solutions at a greater pace. Our attempts to meet these demands subjects our R&D efforts to greater risks.

As a result, substantial and effective R&D and product investment will be required to maintain the competitiveness of our solutions in the market. Technical problems may arise in developing, maintaining, integrating, and operating our solutions as the complexities are increased. Development projects can be lengthy and costly, and may be subject to changing requirements, programming difficulties, a shortage of qualified personnel, and/or unforeseen factors which can result in delays. In addition, we may be responsible for the implementation of new solutions and/or the migration of clients to new solutions, and depending upon the specific solution, we may also be responsible for operations of the solution.

There is an inherent risk in the successful development, implementation, migration, integration, and operation of our solutions as the technological complexities, and the pace at which we must deliver these solutions to market, continue to increase. The risk of making an error that causes significant operational disruption to a client, or results in incorrect customer or vendor data processing that we perform on behalf of our clients, increases proportionately with the frequency and complexity of changes to our solutions and new delivery models. There can be no assurance: (i) of continued market acceptance of our solutions; (ii) that we will be successful in the development of enhancements or new solutions that respond to technological advances or changing client needs at the pace the market demands; or (iii) that we will be successful in supporting the implementation, migration, integration, and/or operations of enhancements or new solutions.

A Reduction in Demand for Our Key Business Support Solutions Could Have a Material Adverse Effect on Our Financial Position and Results of Operations.

Historically, a substantial percentage of our total revenues have been generated from our core outsourced processing product, ACP, and related solutions. These solutions are expected to continue to provide a large percentage of our total revenues in the foreseeable future. Any significant reduction in demand for ACP and related solutions could have a material adverse effect on our financial position and results of operations. Likewise, a large percentage of revenues derived from our software license and services business have been derived from wholesale billing, retail billing and mediation products which are typically associated with large implementation projects. A sudden downward shift in demand for these products or for our professional services associated with these products could have a material adverse effect on our financial position and results of operations.

Variability of Our Quarterly Revenues and Our Failure to Meet Revenue and Earnings Expectations Would Negatively Affect the Market Price for Our Common Stock.

Variability in quarterly revenues and operating results are inherent characteristics of the software and professional services industries. Common causes of a failure to meet revenue and operating expectations in these industries include, among others:

Software license, professional services, and maintenance revenues are a significant percentage of our total revenues. As our total revenues grow, so too does the risk associated with meeting financial expectations for revenues derived from our software licenses, professional services, and maintenance offerings. As a result, there is a proportionately increased likelihood that we may fail to meet revenue and earnings expectations of the investment community. Should we fail to meet analyst expectations, by even a relatively small amount, it would most likely have a disproportionately negative impact upon the market price of our common stock.

Our International Operations Subject Us to Additional Risks.

We currently conduct a portion of our business outside the U.S. We are subject to certain risks associated with operating internationally including the following items:

11

One or more of these factors could have a material adverse effect on our international operations, which could adversely impact our results of operations and financial position.

We May Not Be Successful in the Integration of Our Acquisitions.

As part of our growth strategy, we seek to acquire assets, technology, and businesses which will provide the technology and technical personnel to expedite our product development efforts, provide complementary solutions, or provide access to new markets and clients.

Acquisitions involve a number of risks and difficulties, including: (i) expansion into new markets and business ventures; (ii) the requirement to understand local business practices; (iii) the diversion of management’s attention to the assimilation of acquired operations and personnel; (iv) being bound by acquired client or vendor contracts with unfavorable terms; and (v) potential adverse effects on a company’s operating results for various reasons, including, but not limited to, the following items: (a) the inability to achieve financial targets; (b) the inability to achieve certain operating goals and synergies; (c) costs incurred to exit current or acquired contracts or activities; (d) costs incurred to service any acquisition debt; and (e) the amortization or impairment of acquired intangible assets.

Due to the multiple risks and difficulties associated with any acquisition, there can be no assurance that we will be successful in achieving our expected strategic, operating, and financial goals for any such acquisition.

Our International Operations Require Us To Comply With Applicable U.S. and International Laws and Regulations.

Doing business on a worldwide basis requires our company and our subsidiaries to comply with the laws and the regulations of the U.S. government and various international jurisdictions.  In addition, the number of countries enacting anti-corruption laws and related enforcement activities is increasing. These regulations place restrictions on our operations, trade practices and trade partners. In particular, our international operations are subject to U.S. and foreign anti-corruption laws and regulations such as the Foreign Corrupt Practices Act (“FCPA”), the U.K. Anti-Bribery Act and economic sanction programs administered by OFAC.  

The FCPA prohibits us from providing anything of value to foreign officials for the purposes of influencing official decisions or obtaining or retaining business. In addition, the FCPA imposes accounting standards and requirements on publicly traded U.S. corporations and their foreign affiliates, which are intended to prevent the diversion of corporate funds to the payment of bribes and other improper payments, and to prevent the establishment of “off books” slush funds from which such improper payment can be made. As part of our business, we regularly deal with state-owned business enterprises, the employees of which are considered foreign officials for purposes of the FCPA. In addition, some of the international locations in which we operate lack a developed legal system and have higher than normal levels of corruption. We inform our personnel and third-party sales representatives of the requirements of the FCPA and other anti-corruption laws, including, but not limited to their reporting requirements. We have also developed and will continue to develop and implement systems for formalizing contracting processes, performing due diligence on agents and improving our recordkeeping and auditing practices regarding these regulations. However, there is no guarantee that our employees, third-party sales representatives or other agents have not or will not engage in conduct undetected by our processes and for which we might be held responsible under the FCPA or other anti-corruption laws.

Economic sanctions programs restrict our business dealings with certain countries and individuals. From time to time, certain of our foreign subsidiaries have had limited business dealings with entities in jurisdictions subject to OFAC-administered sanctions. As a result of our worldwide business, we are exposed to a heightened risk of violating anti-corruption laws and OFAC regulations. Violations of these laws and regulations are punishable by civil penalties, including fines, injunctions, asset seizures, debarment from government contracts and revocations or restrictions of licenses, as well as criminal fines and imprisonment.

Our Use of Open Source Software May Subject Us to Certain Intellectual Property-Related Claims or Require Us to Re-Engineer Our Software, Which Could Harm Our Business.

We use open source software in connection with our solutions, processes, and technology. Companies that use or incorporate open source software into their products have, from time to time, faced claims challenging their use, ownership and/or licensing rights associated with that open source software. As a result, we could be subject to suits by parties claiming certain rights to what we believe to be open source software. Some open source software licenses require users who distribute open source software as part of their software to publicly disclose all or part of the source code in their software and make any derivative works of the open source code available on unfavorable terms or at no cost. In addition to risks related to license requirements, use of open source software can lead to greater risks than use of third party commercial software, as open source licensors generally do not provide warranties, support, or controls with respect to origin of the software. Use of open source software also complicates compliance with export-related laws. While we take measures to protect our use of open source software in our solutions, open source license terms may be

12

ambiguous, and many of the risks associated with usage of open source software cannot be eliminated. If we were found to have inappropriately used open source software, we may be required to release our proprietary source code, re-engineer our software, discontinue the sale of certain solutions in the event re-engineering cannot be accomplished on a timely basis, or take other remedial action that may divert resources away from our development efforts, any of which could adversely affect our business, financial position, and results of operations.

We Face Significant Competition in Our Industry.

The market for our solutions is highly competitive. We directly compete with both independent providers and in-house solutions developed by existing and potential clients. In addition, some independent providers are entering into strategic alliances with other independent providers, resulting in either new competitors, or competitors with greater resources. Many of our current and potential competitors have significantly greater financial, marketing, technical, and other competitive resources than our company, many with significant and well-established domestic and international operations. There can be no assurance that we will be able to compete successfully with our existing competitors or with new competitors.

Failure to Protect Our Intellectual Property Rights or Claims by Others That We Infringe Their Intellectual Property Rights Could Substantially Harm Our Business, Financial Position and Results of Operations.

We rely on a combination of trade secret, copyright, trademark, and patent laws in the U.S. and similar laws in other countries, and non-disclosure, confidentiality, and other types of contractual arrangements to establish, maintain, and enforce our intellectual property rights in our solutions. Despite these measures, any of our intellectual property rights could be challenged, invalidated, circumvented, or misappropriated. Further, our contractual arrangements may not effectively prevent disclosure of our confidential information or provide an adequate remedy in the event of unauthorized disclosure of our confidential information. Others may independently discover trade secrets and proprietary information, which may complicate our assertion of trade secret rights against such parties. Costly and time consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position. In addition, the laws of certain countries do not protect proprietary rights to the same extent as the laws of the U.S. Therefore, in certain jurisdictions, we may be unable to protect our proprietary technology adequately against unauthorized third party copying or use, which could adversely affect our competitive position.

Although we hold a limited number of patents and patent applications on some of our solutions, we do not rely upon patents as a primary means of protecting our rights in our intellectual property. In any event, there can be no assurance that our patent applications will be approved, that any issued patents will adequately protect our intellectual property, or that such patents will not be challenged by third parties. Also, much of our business and many of our solutions rely on key technologies developed or licensed by third parties, and we may not be able to obtain or continue to obtain licenses and technologies from these third parties at all or on reasonable terms.

Finally, third parties may claim that we, our clients, licensees or other parties indemnified by us are infringing upon their intellectual property rights. Even if we believe that such claims are without merit, they can be time consuming and costly to defend and distract management’s and technical staff’s attention and resources. Claims of intellectual property infringement also might require us to redesign affected solutions, enter into costly settlement or license agreements or pay costly damage awards, or face a temporary or permanent injunction prohibiting us from marketing or selling certain of our solutions. Even if we have an agreement to indemnify us against such costs, the indemnifying party may be unable to uphold its contractual obligations. If we cannot or do not license the infringed technology on reasonable pricing terms or at all, or substitute similar technology from another source, our business, financial position, and results of operations could be adversely impacted. Our failure to adequately establish, maintain, and protect our intellectual property rights could have a material adverse impact on our business, financial position, and results of operations.

We May Incur Material Restructuring Charges in the Future.

In the past, we have recorded restructuring charges related to involuntary employee terminations, various facility abandonments, and various other restructuring and reorganization activities. We continually evaluate ways to reduce our operating expenses through new restructuring opportunities, including more effective utilization of our assets, workforce, and operating facilities. As a result, there is a risk, which is increased during economic downturns and with expanded global operations, that we may incur material restructuring or reorganization charges in the future.

13

Substantial Impairment of Goodwill and Other Long-lived Assets in the Future May Be Possible.

As a result of various acquisitions and the growth of our company over the last several years, we have approximately $220 million of goodwill, and $111 million of long-lived assets other than goodwill (principally, property and equipment, software, and client contracts) as of December 31, 2015. These long-lived assets are subject to ongoing assessment of possible impairment summarized as follows:

We utilize our market capitalization and/or cash flow models as the primary basis to estimate the fair value amounts used in our goodwill and other long-lived asset impairment valuations. If an impairment was to be recorded in the future, it could materially impact our results of operations in the period such impairment is recognized, but such an impairment charge would be a non-cash expense, and therefore would have no impact on our cash flows.

Failure to Attract and Retain Our Key Management and Other Highly Skilled Personnel Could Have a Material Adverse Effect on Our Business.

Our future success depends in large part on the continued service of our key management, sales, product development, professional services, and operational personnel. We believe that our future success also depends on our ability to attract and retain highly skilled technical, managerial, operational, and sales and marketing personnel, including, in particular, personnel in the areas of R&D, professional services, and technical support. Competition for qualified personnel at times can be intense, particularly in the areas of R&D, conversions, software implementations, and technical support. This risk is heightened with a widely dispersed customer base and employee populations. For these reasons, we may not be successful in attracting and retaining the personnel we require, which could have a material adverse effect on our ability to meet our commitments and new product delivery objectives.

None.

As of December 31, 2015, we were operating in over 30 leased sites around the world, representing over 550,000 square feet.

Our corporate headquarters is located in Englewood, Colorado. In addition, we lease office space in the U.S. in Atlanta, Georgia; Bloomfield, New Jersey; Chicago, Illinois; Columbia, Maryland; Omaha, Nebraska; Oxnard, California; and Philadelphia, Pennsylvania. The leases for these office facilities expire in the years 2016 through 2025. We also maintain leased facilities internationally in Australia, Brazil, Canada, China, Denmark, France, India, Ireland, Lebanon, Malaysia, Philippines, Saudi Arabia, Singapore, South Africa, Sweden, United Arab Emirates, and the U.K. The leases for these international office facilities expire in the years 2016 through 2022. We utilize these office facilities primarily for the following: (i) client services, training, and support; (ii) product and operations support; (iii) systems and programming activities; (iv) professional services staff; (v) R&D activities; (vi) sales and marketing activities; and (vii) general and administrative functions.

Additionally, we lease two statement production and mailing facilities totaling approximately 176,000 square feet. These facilities are located in: (i) Omaha, Nebraska; and (ii) Wakulla County, Florida. The leases for these facilities expire in the 2018 and 2019, respectively.

We believe that our facilities are adequate for our current needs and that additional suitable space will be available as required. We also believe that we will be able to either: (i) extend our current leases as they terminate; or (ii) find alternative space without experiencing a significant increase in cost. See Note 9 to our Financial Statements for information regarding our obligations under our facility leases.

14

From time-to-time, we are involved in litigation relating to claims arising out of our operations in the normal course of business. In the opinion of our management, we are not presently a party to any material pending or threatened legal proceedings.

Not applicable.

Item 6. Selected Financial Data  

The following selected financial data have been derived from our audited financial statements. The selected financial data presented below should be read in conjunction with, and is qualified by reference to, our MD&A and our Financial Statements. The information below is not necessarily indicative of the results of future operations.

On July 1, 2013, we sold a small print operation, and on December 31, 2013, we sold our marketing analytics business marketed under the Quaero brand.  As a result of these divestitures, 2014 revenue levels were approximately $13 million lower when compared to our 2013 revenues generated from these businesses. We sold these businesses for a total of approximately $6 million, and recorded a total loss on the dispositions of approximately $3 million.

In November 2012, we refinanced our Credit Agreement, and as a result, under the refinanced Credit Agreement, we: (i) borrowed $150 million, thus paying down $18 million of outstanding debt; and (ii) extended the term from 2015 to 2017.

See Note 5 to our Financial Statements for additional discussion of our debt.

Forward-Looking Statements

This report contains a number of forward-looking statements relative to our future plans and our expectations concerning our business and the industries we serve. These forward-looking statements are based on assumptions about a number of important factors, and involve risks and uncertainties that could cause actual results to differ materially from estimates contained in the forward-looking statements. Some of the risks that are foreseen by management are outlined above within Item 1A., “Risk Factors”. Item 1A. constitutes an integral part of this report, and readers are strongly encouraged to review this section closely in conjunction with MD&A.

MD&A Basis of Discussion - Impact of Divestitures and Acquisitions

Our Consolidated Statements of Income (“Income Statements” or “Income Statement”) for the years ended December 31, 2015, 2014, and 2013 reflect the results of operations for the following acquisitions and divestitures:

In February 2016, this business was acquired by a third-party.  Based on the terms of our agreement with former management personnel, we have received additional proceeds which were contingent upon a liquidation event, as defined in the agreement, resulting in an additional gain on the sale of approximately $6.6 million.  The additional gain on sale will be recognized in the first quarter of 2016, and will be included in restructuring and reorganization charges in our Income Statement.

As a result of these acquisitions and divestitures, amounts may not be comparable between years due to the timing of the transactions. The comparable differences have been described below where relevant or significant. Overall, the acquisition and divestiture activity was not material to our operating results in 2015, 2014, or 2013.

Management Overview

Results of Operations. A summary of our results of operations for 2015 and 2014, and other key performance metrics are as follows (in thousands, except percentages and per share amounts):

Revenues. Our revenues for 2015 were $752.5 million, a slight increase when compared to $751.3 million for 2014. The increase can be primarily attributed to a 3% increase in our processing revenues, offset by unfavorable foreign currency movements, which had a negative impact to total revenues of approximately $15 million.  The growth in our processing revenues for 2015 was driven largely

22

by the migration of new customer accounts onto ACP, and the continued revenue growth from our Ascendon solution and international managed services offering, offset by some of the challenges we experienced in our software and services revenues.

Operating Results. Operating income for 2015 was $113.1 million, or a 15.0% operating income margin percentage, compared to $75.7 million, or a 10.1% operating income margin percentage for 2014, with the increase due to lower operating expenses (driven primarily by foreign currency movements, focus on cost improvements, and lower restructuring and reorganization charges), and the scale benefits we are achieving from increasing the number of customer accounts and clients on our solutions.

Diluted EPS. Diluted EPS for 2015 was $1.87 compared to $1.06 for 2014 with the increase primarily attributed to the higher operating margin.

Balance Sheet and Cash Flows. As of December 31, 2015, we had cash, cash equivalents, and short-term investments of $240.9 million, as compared to $201.8 million as of December 31, 2014. Cash flows from operating activities for 2015 were $137.0 million, compared to $83.7 million for 2014, with the fluctuations between years caused primarily by timing items within our working capital.  See the Liquidity section below for further discussion of our cash flows.

Capital Planning Activities

In February 2015, we announced a planned increase in our capital allocation to shareholders and an improvement in our capital structure that included the following key items:

In 2016, we plan to continue this capital allocation strategy as follows:

Significant Client Relationships

Comcast. Comcast continues to be our largest client. For 2015 and 2014, revenues from Comcast were $177 million and $162 million, respectively, representing approximately 24% and 22% of our total revenues. This increase is driven primarily by the migration of additional Comcast customer accounts to our platform, as noted below.  Our agreement with Comcast runs through June 30, 2019, with an option to extend the agreement for two consecutive one-year terms by exercising the renewal options no later than January 1, 2019 for the first extension option, and January 1, 2020 for the second extension option.

During the fourth quarter of 2014, Comcast added over two million residential customer accounts onto ACP and approximately two million more during 2015. We believe we have the opportunity to migrate up to an additional six million Comcast customer accounts that are currently on one of our competitor’s platforms onto our solution over the next several years as part of Comcast’s future standardization initiatives for their residential business. However, the timing of and the number of additional customer accounts to be migrated to CSG, if any, is at the discretion of Comcast.  Therefore, there can be no assurances as to the timing or the number of additional customer accounts migrated to us by Comcast, or whether we will experience any further material increase in revenues or profits under the Amended Agreement. See our Risk factors for additional discussion.

A copy of the Comcast agreement and related amendments, with confidential information redacted, is included in the exhibits to our periodic filings with the SEC.

DISH. DISH is our second largest client. For 2015 and 2014, revenues from DISH were $107 million and $112 million, respectively, representing approximately 14% and 15% of our total revenues. Our agreement with DISH runs through December 31, 2017.

The DISH agreement and related amendments, with confidential information redacted, is included in the exhibits to our periodic filings with the SEC.

23

Time Warner. Time Warner is our third largest client. For 2015 and 2014, revenues from Time Warner were $87 million and $83 million, respectively, representing approximately 12% and 11% of our total revenues. Our agreement with Time Warner runs through March 31, 2017, with an option to extend the term for one additional year by exercising the renewal option on or before September 30, 2016.

The Time Warner processing agreement and related amendments, with confidential information redacted, is included in the exhibits to our periodic filings with the SEC.

Critical Accounting Policies

The preparation of our Financial Statements in conformity with accounting principles generally accepted in the U.S. requires us to select appropriate accounting policies, and to make judgments and estimates affecting the application of those accounting policies. In applying our accounting policies, different business conditions or the use of different assumptions may result in materially different amounts reported in our Financial Statements.

We have identified the most critical accounting policies that affect our financial position and the results of our operations. These critical accounting policies were determined by considering our accounting policies that involve the most complex or subjective decisions or assessments. The most critical accounting policies identified relate to: (i) revenue recognition; (ii) impairment assessments of goodwill and other long-lived assets; (iii) income taxes; and (iv) loss contingencies. These critical accounting policies, as well as our other significant accounting policies, are disclosed in the notes to our Financial Statements.

Revenue Recognition. The revenue recognition policy that involves the most complex or subjective decisions or assessments that may have a material impact on our business’ operations relates to the accounting for certain software license and services arrangements.

The accounting for software license arrangements, especially when software is sold in a multiple-element arrangement, can be complex and may require considerable judgment. Key factors considered in accounting for software license and related services include the following criteria: (i) the identification of the separate elements of the arrangement; (ii) the determination of whether any undelivered elements are essential to the functionality of the delivered elements; (iii) the assessment of whether the software, if hosted, should be accounted for as a services arrangement and thus outside the scope of the software revenue recognition literature; (iv) the determination of vendor specific objective evidence (“VSOE”) of fair value for the undelivered element(s) of the arrangement; (v) the assessment of whether the software license fees are fixed or determinable; (vi) the determination as to whether the fees are considered collectible; and (vii) the assessment of whether services included in the arrangement represent significant production,

24

customization or modification of the software. The evaluation of these factors, and the ultimate revenue recognition decision, requires significant judgments to be made by us. The judgments made in this area could have a significant effect on revenues recognized in any period by changing the amount and/or the timing of the revenue recognized. In addition, because software licenses typically have little or no direct, incremental costs related to the recognition of the revenue, these judgments could also have a significant effect on our results of operations.

The initial sale of our software products generally requires significant production, modification or customization and thus falls under the guidelines of contract accounting. In these software license arrangements, the software license and professional services elements of the arrangement fee are typically combined and subject to contract accounting using the percentage-of-completion (“POC”) method of accounting. Under the POC method of accounting, software license and professional services revenues are typically recognized as the professional services related to the software implementation project are performed. We are using hours performed on the project as the measure to determine the percentage of the work completed.

A portion of our professional services revenues does not include an element of software delivery (e.g., business consulting services, etc.), and thus, do not fall within the scope of specific authoritative accounting literature for software arrangements. In these cases, revenues from fixed-price, professional service contracts are recognized using a method consistent with the proportional performance method, which is relatively consistent with our POC methodology. Under a proportional performance model, revenue is recognized by allocating revenue between reporting periods based on relative service provided in each reporting period, and costs are generally recognized as incurred. We utilize an input-based approach (i.e., hours worked) for purposes of measuring performance on these types of contracts. Our input measure is considered a reasonable surrogate for an output measure. In instances when the work performed on fixed price agreements is of relatively short duration, or if we are unable to make reasonably dependable estimates at the outset of the arrangement, we use the completed contract method of accounting whereby revenue is recognized when the work is completed.

Our use of the POC and proportional performance methods of accounting on professional services engagements requires estimates of the total project revenues, total project costs and the expected hours necessary to complete a project. Changes in estimates as a result of additional information or experience on a project as work progresses are inherent characteristics of the POC and proportional performance methods of accounting as we are exposed to various business risks in completing these engagements. The estimation process to support these methods of accounting is more difficult for projects of greater length and/or complexity. The judgments and estimates made in this area could: (i) have a significant effect on revenues recognized in any period by changing the amount and/or the timing of the revenue recognized; and/or (ii) impact the expected profitability of a project, including whether an overall loss on an arrangement has occurred. To mitigate the inherent risks in using the POC and proportional performance methods of accounting, we track our performance on projects and reevaluate the appropriateness of our estimates as part of our monthly accounting cycle.

Revenues are recognized only if we determine that the collection of the fees included in an arrangement is considered probable (i.e., we expect the client to pay all amounts in full when invoiced). In making our determination of collectibility for revenue recognition purposes, we consider a number of factors depending upon the specific aspects of an arrangement, which may include, but is not limited to, the following items: (i) an assessment of the client’s specific credit worthiness, evidenced by its current financial position and/or recent operating results, credit ratings, and/or a bankruptcy filing status (as applicable); (ii) the client’s current accounts receivable status and/or its historical payment patterns with us (as applicable); (iii) the economic condition of the industry in which the client conducts the majority of its business; and/or (iv) the economic conditions and/or political stability of the country or region in which the client is domiciled and/or conducts the majority of its business. The evaluation of these factors, and the ultimate determination of collectibility, requires significant judgments to be made by us. The judgments made in this area could have a significant effect on revenues recognized in any period by changing the amount and/or the timing of the revenue recognized.

Impairment Assessments of Goodwill and Other Long-Lived Assets.

Goodwill. Goodwill is required to be tested for impairment on an annual basis. We have elected to do our annual test for possible impairment as of July 31 of each year. In addition to this annual requirement, goodwill is required to be evaluated for possible impairment on a periodic basis (e.g., quarterly) if events occur or circumstances change that could indicate a possible impairment may have occurred. Goodwill is considered impaired if the carrying value of the reporting unit, which includes the goodwill, is greater than the estimated fair value of the reporting unit. If it is determined that an impairment has occurred, an impairment loss (equal to the excess of the carrying value of the goodwill over its estimated fair value) is recorded.

As of July 31, 2015, we had goodwill of approximately $225 million, which was assigned to a single reporting unit. Since we had only a single reporting unit, we used our public market capitalization as our primary means to estimate the fair value for that single reporting unit. Since our market capitalization exceeded the carrying value of our single reporting unit by a significant margin, we concluded there was no impairment of goodwill.

25

We believe that our approach for testing our goodwill for impairment was appropriate. However, if we experience a significant drop in our market capitalization due to company performance, and/or broader market conditions, it may result in an impairment loss. If a goodwill impairment was to be recorded in the future, it would likely materially impact our results of operations in the period such impairment is recognized, but such an impairment charge would be a non-cash expense, and therefore would have no impact on our cash flows, or on the financial position of our company.

Other Long-lived Assets. Long-lived assets other than goodwill, which for us relates primarily to property and equipment, software, and client contracts, are required to be evaluated for possible impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. A long-lived asset (or group of long-lived assets) is impaired if estimated future undiscounted cash flows associated with that asset, without consideration of interest, are insufficient to recover the carrying amount of the long-lived asset. Once deemed impaired, even if by $1, the long-lived asset is written down to its fair value which could be considerably less than the carrying amount or future undiscounted cash flows. The determination of estimated future cash flows and, if required, the determination of the fair value of a long-lived asset, are by their nature, highly subjective judgments. Changes to one or more of the assumptions utilized in such an analysis could materially affect our impairment conclusions for long-lived assets.

Income Taxes. We are required to estimate our income tax liability in each jurisdiction in which we operate, which includes the U.S. (including both Federal and state income taxes) and numerous foreign countries.

Various judgments are required in evaluating our income tax positions and determining our provisions for income taxes. During the ordinary course of our business, there are certain transactions and calculations for which the ultimate income tax determination may be uncertain. In addition, we may be subject to examination of our income tax returns by various tax authorities which could result in adverse outcomes. For these reasons, we establish a liability associated with unrecognized tax benefits based on estimates of whether additional taxes and interest may be due. We adjust this liability based upon changing facts and circumstances, such as the closing of a tax audit, the closing of a tax year upon the expiration of a statute of limitations, or the refinement of an estimate. Should any of the factors considered in determining the adequacy of this liability change significantly, an adjustment to the liability may be necessary. Because of the potential significance of these issues, such an adjustment could be material.

One of the more complex items within our income tax expense is the determination of our annual research and experimentation income tax credit (“R&D credit”).  We incur more than $100 million annually in R&D expense.  The calculation of the R&D tax credit involves the identification of qualifying projects, and then an estimation of the qualifying costs for such projects.  Because of the size, nature, and the number of projects worked on in any given year, the calculation can become complex and certain judgments are necessary in determining the amount of the R&D credits claimed.  In fact, during the fourth quarter of 2015, we corrected our financial statements for an error in the calculation of R&D credit amounts recorded within our 2014, 2013, and 2012 income tax provisions.  See further discussion below and Note 7 to our Financial Statements for additional information regarding this immaterial correction.

Loss Contingencies. In the ordinary course of business, we are subject to claims (and potential claims) related to various items including but not limited to the following: (i) legal and regulatory matters; (ii) client and vendor contracts; (iii) product and service delivery matters; and (iv) labor matters. Accounting and disclosure requirements for loss contingencies requires us to assess the likelihood of any adverse judgments in or outcomes to these matters, as well as the potential ranges of probable losses. A determination of the amount of reserves for such contingencies, if any, for these contingencies is based on an analysis of the issues, often with the assistance of legal counsel. The evaluation of such issues, and our ultimate accounting and disclosure decisions, are by their nature, subject to various estimates and highly subjective judgments. Should any of the factors considered in determining the adequacy of any required reserves change significantly, an adjustment to the reserves may be necessary. Because of the potential significance of these issues, such an adjustment could be material.

Detailed Discussion of Results of Operations

Total Revenues. Total revenues for: (i) 2015 were $752.5 million, a slight increase from $751.3 million for 2014; and (ii) 2014 increased 1% to $751.3 million, from $747.5 million for 2013.

26

The components of total revenues, discussed in more detail below, are as follows:  

Processing and Related Services Revenues. Processing and related services revenues for: (i) 2015 increased 3% to $577.4 million, from $562.1 million for 2014; and (ii) 2014 increased 5% to $562.1 million, from $537.5 million for 2013.

Additionally, amortization of the investments in client contracts intangible asset (reflected as a reduction of processing revenues) for 2015, 2014, and 2013 was $5.2 million, $6.4 million, and $6.2 million, respectively.

Software and Services Revenues. Software and services revenues for: (i) 2015 decreased 9% to $93.7 million, from $102.6 million for 2014; and (ii) 2014 decreased 14% to $102.6 million, from $119.0 million for 2013.

Maintenance Revenues. Maintenance revenues for: (i) 2015 decreased 6% to $81.4 million, from $86.6 million for 2014; and (ii) 2014 decreased 5% to $86.6 million, from $91.0 million for 2013.

Total Operating Expenses. Our operating expenses for: (i) 2015 decreased 5% to $639.4 million, from $675.6 million for 2014; and (ii) 2014 increased 1% to $675.6 million, from $670.8 million for 2013.

27

The components of total expenses are discussed in more detail below.

Cost of Processing and Related Services (Exclusive of Depreciation). The cost of processing and related services revenues consists principally of the following: (i) data processing and network communications costs; (ii) statement production costs (e.g., labor, paper, envelopes, equipment, equipment maintenance, etc.); (iii) client support organizations (e.g., our client support call center, account management, etc.); (iv) various product delivery and support organizations (e.g., managed services delivery, product management, product maintenance, etc.); (v) facilities and infrastructure costs related to the statement production and support organizations; and (vi) amortization of acquired intangibles. The costs related to new product development (including significant enhancements to existing products and services) are included in R&D expenses.

The cost of processing and related services for: (i) 2015 decreased 2% to $270.7 million, from $277.1 million for 2014; and (ii) 2014 increased 9% to $277.1 million, from $253.8 million for 2013.  Total processing and related services cost of revenues as a percentage of our processing and related services revenues for 2015, 2014, and 2013, were 46.9%, 49.3%, and 47.2%, respectively.

Cost of Software and Services (Exclusive of Depreciation). The cost of software and services revenues consists principally of the following: (i) various product support organizations (e.g., product management and delivery, etc.); (ii) professional services organization; (iii) facilities and infrastructure costs related to these organizations; and (iv) third-party software costs and/or royalties related to certain software products. The costs related to new product development (including significant enhancements to existing products and services) are included in R&D expenses.

The cost of software and services for: (i) 2015 decreased 14% to $68.6 million, from $79.6 million for 2014; and (ii) 2014 decreased 5% to $79.6 million, from $84.2 million for 2013.  

Total cost of software and services as a percentage of our software and services revenues for 2015, 2014, and 2013, were 73.2%, 77.6%, and 70.8%, respectively, with the level and variability of these percentages reflective of the negative impact of two large implementation projects.  In the first quarter of 2014, we incurred a loss of approximately $4 million on a large software and implementation project (to be substantially completed in 2019) due to cost overruns.  In the first quarter of 2015, we incurred a loss of approximately $5 million on another large software and services implementation project (to be substantially completed in 2016) due to estimated cost overruns.  

Variability in quarterly revenues and operating results are inherent characteristics of companies that sell software licenses and perform professional services.  Our quarterly revenues for software licenses and professional services may fluctuate, depending on various factors, including the timing of executed contracts and revenue recognition, and the delivery of contracted solutions.  However, the costs associated with software and professional services revenues are not subject to the same degree of variability (e.g., these costs are generally fixed in nature within a relatively short period of time), and thus, fluctuations in our cost of software and services as a percentage of our software and services revenues will likely occur between periods.  

28

Cost of Maintenance (Exclusive of Depreciation). The cost of maintenance consists principally of the following:  (i) client support organizations (e.g., our client support call center, account management, etc.); (ii) various product support organizations (e.g., product maintenance, etc.); (iii) facilities and infrastructure costs related to these organizations; and (iv) amortization of acquired intangibles.

The cost of maintenance for: (i) 2015 increased 24% to $40.4 million, from $32.6 million for 2014; and (ii) 2014 decreased 17% to $32.6 million, from $39.2 million for 2013. Total cost of maintenance as a percentage of our maintenance revenues for 2015, 2014, and 2013 were 49.6%, 37.7%, and 43.0%, respectively.

R&D Expense (Exclusive of Depreciation). R&D expense for: (i) 2015 decreased 3% to $102.0 million, from $104.7 million for 2014; and (ii) 2014 decreased 5% to $104.7 million, from $110.0 million for 2013.

Our R&D efforts are focused on the continued evolution of our solutions that enable service providers worldwide to provide a more personalized customer experience while turning transactions into revenues. This includes the continued investment in our business support solutions aimed at improving a providers’ time-to-market for new offerings, flexibility, scalability, and total cost of ownership.

As a percentage of total revenues, R&D expense for 2015, 2014, and 2013 was 13.5%, 13.9%, and 14.7%, respectively. We expect that our R&D investment activities in the near-term will be relatively consistent with those of the past few years, with the level of R&D spend highly dependent upon the opportunities that we see in our markets.

Selling, General and Administrative Expense (Exclusive of Depreciation) (“SG&A”). SG&A expense for: (i) 2015 decreased 9% to $139.8 million, from $153.5 million for 2014; and (ii) 2014 increased 1% to $153.5 million, from $152.6 million for 2013.

Additionally, it should be noted that 2014 SG&A expense benefited from a settlement agreement ending litigation that we had asserted against a third party for patent infringement and misappropriation of trade secrets.  In exchange for the release from the lawsuit we initiated, we recorded $3.9 million (net of a time value discount and legal costs incurred) as a reduction of SG&A expenses in that period.

As a percentage of total revenues, SG&A expense for 2015, 2014, and 2013 was 18.6%, 20.4%, and 20.4%, respectively.

Depreciation Expense. Depreciation expense for all property and equipment is reflected separately in the aggregate and is not included in the cost of revenues or the other components of operating expenses. Depreciation expense for:  (i) 2015 was $14.8 million, a slight increase from $14.1 million for 2014; and (ii) 2014 decreased 24% to $14.1 million, from $18.6 million for 2013, with the decrease the result of certain assets becoming fully depreciated, and to a lesser degree, the assets sold as part of our 2013 divestitures.

Restructuring and Reorganization Charges. In 2015, 2014, and 2013, we implemented various cost reduction and efficiency initiatives that resulted in restructuring and reorganization charges of $3.1 million, $14.0 million, and $12.4 million, respectively. These initiatives included: (i) the divestitures of our Invotas cyber security business, our Quaero marketing analytics business, and a small print operation; (ii) the reorganization of our Content Direct solution to facilitate its alignment across our offerings, including

29

management programs and incentives; (iii) reducing our workforce to further align it around our long-term growth initiatives; (iv) the termination of our previously frozen defined benefit pension plan; and (v) the abandonment of space at some of our facility locations. We completed these initiatives in order to better align and allocate our resources around our long-term growth initiatives.

See Note 6 to our Financial Statements for additional information regarding these initiatives.

Operating Income. Operating income and operating income margin for: (i) 2015 was $113.1 million, or 15.0% of total revenues, compared to $75.7 million, or 10.1% of total revenues for 2014; and (ii) 2014 was $75.7 million, or 10.1% of total revenues, compared to $76.7 million, or 10.3% of total revenues for 2013.

Interest Expense and Amortization of Original Issue Discount (“OID”). Our interest expense relates primarily to our 2010 Convertible Notes and our Credit Agreement. See Note 5 to our Financial Statements for additional discussion of our long-term debt, to include the non-cash interest expense related to the amortization of the convertible debt OID.

Interest expense for: (i) 2015 increased slightly to $11.0 million, from $10.5 million for 2014; and (ii) 2014 decreased to $10.5 million, from $11.6 million for 2013.

Income Tax Provision. Our effective income tax rates for 2015, 2014, and 2013 were as follows:

30

Liquidity

Cash and Liquidity. As of December 31, 2015, our principal sources of liquidity included cash, cash equivalents, and short-term investments of $240.9 million, compared to $201.8 million as of December 31, 2014. We generally invest our excess cash balances in low-risk, short-term investments to limit our exposure to market and credit risks.

At December 31, 2015, as part of our 2015 Agreement, we have a $200 million senior secured revolving loan facility (“Revolver”) with a syndicate of financial institutions that expires in February 2020.  As of December 31, 2015, there were no borrowings outstanding on the Revolver. The Credit Agreement contains customary affirmative covenants and financial covenants. As of December 31, 2015, and the date of this filing, we believe that we are in compliance with the provisions of the Credit Agreement.

Our cash, cash equivalents, and short-term investment balances as of the end of the indicated periods were located in the following geographical regions (in thousands):

We generally have ready access to substantially all of our cash, cash equivalents, and short-term investment balances, but may face limitations on moving cash out of certain foreign jurisdictions due to currency controls. As of December 31, 2015, we had $5.0 million of cash restricted as to use to collateralize outstanding letters of credit.

Cash Flows From Operating Activities. We calculate our cash flows from operating activities beginning with net income, adding back the impact of non-cash items or non-operating activity (e.g., depreciation, amortization, amortization of OID, impairments, deferred income taxes, stock-based compensation, etc.), and then factoring in the impact of changes in operating assets and liabilities.

Our primary source of cash is from our operating activities. Our current business model consists of a significant amount of recurring revenue sources related to our long-term managed services arrangements (mostly billed monthly), and software maintenance agreements (billed monthly, quarterly, or annually). This recurring revenue base provides us with a reliable and predictable source of cash. In addition, software license fees and professional services revenues are sources of cash, but the payment streams for these items are less predictable.

The primary use of our cash is to fund our operating activities. Over half of our total operating costs relate to labor costs (both employees and contracted labor) for the following: (i) compensation; (ii) related fringe benefits; and (iii) reimbursements for travel and entertainment expenses. The other primary cash requirements for our operating expenses consist of: (i) data processing and related services and communication lines for our outsourced processing business; (ii) paper, envelopes, and related supplies for our statement processing solutions; (iii) hardware and software; and (iv) rent and related facility costs. These items are purchased under a variety of both short-term and long-term contractual commitments. A summary of our material contractual obligations is provided below.

See “Cash Flows From Investing Activities” and “Cash Flows From Financing Activities” below for the other primary sources and uses of our cash.

Our 2015 and 2014 net cash flows from operating activities, broken out between operations and changes in operating assets and liabilities, for the indicated quarterly periods are as follows (in thousands):  

31

We believe the above table illustrates our ability to generate recurring quarterly cash flows from our operations, and the importance of managing our working capital items.  The quarterly and annual variations in our net cash provided by operating activities are related mostly to the changes in our operating assets and liabilities (related mostly to fluctuations in timing for such things as client payments and changes in accrued expenses), and generally over longer periods of time, do not significantly impact our cash flows from operations.

Significant fluctuations in key operating assets and liabilities between 2015 and 2014 that impacted our cash flows from operating activities are as follows:

Billed Trade Accounts Receivable

Management of our billed accounts receivable is one of the primary factors in maintaining strong quarterly cash flows from operating activities. Our billed trade accounts receivable balance includes significant billings for several non-revenue items (primarily postage, sales tax, and deferred revenue items). As a result, we evaluate our performance in collecting our accounts receivable through our calculation of days billings outstanding (“DBO”) rather than a typical days sales outstanding (“DSO”) calculation. DBO is calculated by taking the average monthly net trade accounts receivable balance for the period divided by billings for the period (including non-revenue items).

Our gross and net billed trade accounts receivable and related allowance for doubtful accounts receivable (“Allowance”) as of the end of the indicated quarterly periods, and the related DBOs for the quarters then ended, are as follows (in thousands, except DBOs):

The increases in gross and net billed accounts receivable at March 31, 2014, June 30, 2014, and September 30, 2014 are primarily related to the timing around certain recurring customer payments that were delayed at each quarter end, thus negatively impacting our DBO for the second and third quarters of 2014.

32

As a global provider of software and professional services, a portion of our accounts receivable balance relates to clients outside the U.S.  As a result, this diversity in the geographic composition of our client base may adversely impact our DBOs as longer billing cycles (i.e., billing terms and cash collection cycles) are an inherent characteristic of international software and professional services transactions.  For example, our ability to bill (i.e., send an invoice) and collect arrangement fees may be dependent upon, among other things: (i) the completion of various client administrative matters, local country billing protocols and processes (including local cultural differences), and/or non-client administrative matters; (ii) us meeting certain contractual invoicing milestones; or (iii) the overall project status in certain situations in which we act as a subcontractor to another vendor on a project.

Unbilled Trade Accounts Receivable

Revenue earned and recognized prior to the scheduled billing date of an item is reflected as unbilled accounts receivable. Our unbilled accounts receivable as of the end of the indicated periods are as follows (in thousands):

The unbilled accounts receivable balances above are primarily the result of several transactions with various milestone and contractual billing dates which have not yet been reached.  Unbilled accounts receivable are an inherent characteristic of certain software and professional services transactions and may fluctuate between quarters, as these type of transactions typically have scheduled invoicing terms over several quarters, as well as certain milestone billing events.

Accrued Employee Compensation

Accrued employee compensation increased $8.2 million to $59.6 million as of December 31, 2015, compared to $51.4 million as of December 31, 2014, with the increase mainly due to an increase in accrued incentive compensation.

Income Taxes Payable/Receivable

For 2015, our cash flows provided by operating activities related to income taxes payable/receivable was $9.0 million, compared to cash flows used in operating activities related to income taxes payable/receivable of $2.3 million for 2014.  This net $11.2 million change is primarily due to the timing of our estimated Federal and state income tax payments.

Cash Flows From Investing Activities. Our typical investing activities consist of purchases/sales of short-term investments, purchases of property and equipment, and investments in client contracts, which are discussed below.

Purchases/Sales of Short-term Investments.

During 2015, 2014, and 2013 we purchased $181.6 million, $190.4 million, and $183.6 million, respectively, and sold or had mature $193.0 million, $197.5 million, and $89.7 million, respectively, of short-term investments. We continually evaluate the possible uses of our excess cash balances and will likely purchase and sell additional short-term investments in the future.

Property and Equipment/Client Contracts.

Our annual capital expenditures for property and equipment, and investments in client contracts were as follows (in thousands):

Our capital expenditures for these periods consisted principally of investments in: (i) computer hardware, software, and related equipment; (ii) facilities and internal infrastructure items; and (iii) statement production equipment.

Our investments in client contracts for 2015, 2014, and 2013 relate primarily to: (i) cash incentives provided to clients to convert their customer accounts to, or retain their customer’s accounts on, our managed services solutions; and (ii) direct and

33

incremental costs incurred for conversion/set-up services related to long-term managed services arrangements where we are required to defer conversion/set-up services fees and recognize those fees as the related services are performed. For 2015, 2014, and 2013 our: (i) investments in client contracts related to cash incentives were $1.8 million, $3.0 million, and $6.5 million, respectively; and (ii) the deferral of costs related to conversion/set-up services provided under long-term managed services contracts were $6.2 million, $2.6 million, and $0.6 million, respectively.

Cash Flows From Financing Activities. Our financing activities typically consist of various debt-related transactions and activities with our common stock, which are discussed below.

Issuance of Common Stock.

Proceeds from the issuance of common stock for 2015, 2014, and 2013 were $1.5 million, $1.4 million, and $1.6 million, respectively, and relates primarily to employee stock purchase plan purchases.

Repurchase of Common Stock.

During 2015, 2014, and 2013, we repurchased approximately 1,838,000, 733,000, and 500,000 shares of our common stock under the guidelines of our Stock Repurchase Program for $56.9 million, $19.1 million, and $10.1 million, respectively.  Of our 2015 stock repurchases, $50 million was repurchased under an ASR Agreement entered into in March 2015.  

Additionally, outside of our Stock Repurchase Program, during 2015, 2014, and 2013, we repurchased from our employees and then cancelled approximately 265,000 shares, 252,000 shares, and 264,000 shares of our common stock for $8.1 million, $6.9 million, and $5.4 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted stock under our stock incentive plans.

Cash Dividends Paid on Common Stock.

During 2015, 2014, and 2013, the Board approved dividend payments totaling $22.9 million, $21.3 million, and $15.2 million, respectively, of which $22.2 million, $20.5 million, and $14.5 million, respectively, had been paid through December 31, 2015, 2014, and 2013 (with the remaining amount attributed to unvested incentive shares to be paid upon vesting).

Long-term debt.

During 2015, 2014, and 2013 we made a total of $7.5 million, $15.0 million, and $15.0 million, respectively, of principal repayments on our long-term debt balance.  Additionally, during 2015 we amended our 2012 Credit Agreement and as a result, we repaid the outstanding principal balance of $120.0 million and borrowed $150.0 million under the 2015 Credit Agreement, resulting in a net increase of available cash of $30.0 million.  As part of this refinancing, we paid $2.7 million of deferred financing costs.  As of December 31, 2015, the total Term Loan balance outstanding was $142.5 million.

See Note 5 to our Financial Statements for additional discussion of our long-term debt.

Contractual Obligations and Other Commercial Commitments and Contingencies

We have various contractual obligations that are recorded as liabilities in our Consolidated Balance Sheets. Other items, such as certain purchase commitments and other executory contracts, are not recognized as liabilities in our Balance Sheet but are required to be disclosed.

The following table summarizes our significant contractual obligations and commercial commitments as of December 31, 2015, and the future periods in which such obligations are expected to be settled in cash (in thousands).

34

The contractual obligation amounts reflected for our long-term debt are as of December 31, 2015, based upon the following assumptions:

Our long-term debt obligations are discussed in more detail in Note 5 to our Financial Statements.

The operating leases are discussed in Note 9 to our Financial Statements. Our purchase obligations consist primarily of our expected minimum base fees under the Infocrossing service agreement (discussed in Note 9 to our Financial Statements), hardware and software maintenance agreements, and business continuity planning services.

The other obligations reflect the requirement for us to pay cash of approximately $17 million ratably over three years related to the deferred income tax liabilities associated with our repurchase of the 2004 Convertible Debt Securities as discussed in Note 7 to our Financial Statements.

Of the total contractual obligations and commercial commitments above, approximately $331 million is reflected on our Balance Sheet.

Capital Resources

The following are the key items to consider in assessing our sources and uses of capital resources:

Current Sources of Capital Resources.

35

Uses/Potential Uses of Capital Resources. Below are the key items to consider in assessing our uses/potential uses of capital resources:

In February 2015, we announced our intent to repurchase up to $150 million under our Stock Repurchase Program over the next three years (2015-2017).  During the year ended December 31, 2015, we repurchased 1.8 million shares of our common stock for $56.9 million (weighted-average price of $31.00 per share) under our Stock Repurchase Program, of which $50 million was repurchased under an ASR plan.  We recently announced our intent to repurchase a minimum of up to $50 million of shares in 2016.  

Under our Stock Repurchase Program, we may repurchase shares in the open market or a privately negotiated transaction, including through an ASR plan or under a SEC Rule 10b5-1 plan.  The actual timing and amount of the share repurchases will be dependent on the then current market conditions and other business-related factors.  Our common stock repurchases are discussed in more detail in Note 10 to our Financial Statements.

We have issued stock warrants to Comcast (the “Warrant Agreement”) for the right to purchase up to approximately 2.9 million shares of our common stock (the “Stock Warrants”) as an additional incentive for Comcast to migrate new customer accounts to ACP.  Once vested, Comcast may exercise the Stock Warrants and elect either physical delivery of common shares or net share settlement (cashless exercise).  Alternatively, the exercise of the Stock Warrants may be settled with cash based solely on our approval, or if Comcast were to beneficially own or control in excess of 19.99% of the common stock or voting of the Company.  As of December 31, 2015, approximately 1 million Stock Warrants had vested based on the terms of the Warrant Agreement, and none of these Stock Warrants have been exercised to date.  The Stock Warrants are discussed in more detail in Note 10 to our Financial Statements.  

Upon any conversion of the 2010 Convertible Notes, we will settle our conversion obligation as follows:  (i) we are required to pay cash for 100% of the par value of the 2010 Convertible Notes that are converted; and (ii) to the extent the value of our conversion obligation exceeds the par value, we can satisfy the remaining conversion obligation in our common stock, cash or any combination of our common stock and cash, at our discretion.  Based on our December 31, 2015 closing stock price of $35.98 per share, the 2010 Convertible Notes would have had a total settlement value of approximately $235 million.  Based on our February 22, 2016 closing stock price of $38.02 per share, the 2010 Convertible Notes would have had a total settlement value of approximately $250 million.  Given the current market value of the 2010 Convertible Notes exceeds the value holders would receive upon conversion if our common stock remains at the current levels, we believe that holders may not have a significant economic incentive to convert at this time.  However, there can be no assurances as to the conversion decisions made by the holders during the conversion period.  If none of the

36

2010 Convertible Notes are converted, our cash debt service for the 2010 Convertible Notes for 2016 is $4.5 million of interest payments.

Our 2015 Credit Agreement mandatory repayments and the cash interest expense (based upon current interest rates) for 2016 is $7.5 million, and $3.9 million, respectively. We have the ability to make prepayments on our 2015 Credit Agreement without penalty.  

Our long-term debt obligations are discussed in more detail in Note 5 to our Financial Statements.  

In summary, we expect to continue to have material needs for capital resources going forward, as noted above. We believe that our current cash, cash equivalents and short-term investments balances and our 2015 Revolver, together with cash expected to be generated in the future from our current operating activities, will be sufficient to meet our anticipated capital resource requirements for at least the next 12 months. We also believe we could obtain additional capital through other debt sources which may be available to us if deemed appropriate.

Market risk is the potential loss arising from adverse changes in market rates and prices. As of December 31, 2015, we are exposed to various market risks, including changes in interest rates, fluctuations and changes in the market value of our cash equivalents and short-term investments, and changes in foreign currency exchange rates. We have not historically entered into derivatives or other financial instruments for trading or speculative purposes.

Interest Rate Risk

Long-Term Debt. The interest rate on our 2010 Convertible Notes is fixed, and thus, as it relates to our convertible debt borrowings, we are not exposed to changes in interest rates.

The interest rates under our Credit Agreement are based upon an adjusted LIBOR rate plus an applicable margin, or an alternate base rate plus an applicable margin. Refer to Note 5 to our Financial Statements for further details of our long-term debt.

A hypothetical adverse change of 10% in the December 31, 2015 adjusted LIBOR rate would not have had a material impact upon our results of operations.

Market Risk

Cash Equivalents and Short-Term Investments. Our cash and cash equivalents as of December 31, 2015 and 2014 were $132.6 million and $81.7 million, respectively. Certain of our cash balances are “swept” into overnight money market accounts on a daily basis, and at times, any excess funds are invested in low-risk, somewhat longer term, cash equivalent instruments and short-term investments. Our cash equivalents are invested primarily in institutional money market funds, commercial paper, and time deposits held at major banks. We have minimal market risk for our cash and cash equivalents due to the relatively short maturities of the instruments.

Our short-term investments as of December 31, 2015 and 2014 were $108.3 million and $120.1 million, respectively. Currently, we utilize short-term investments as a means to invest our excess cash only in the U.S. The day-to-day management of our short-term investments is performed by a large financial institution in the U.S., using strict and formal investment guidelines approved by our Board. Under these guidelines, short-term investments are limited to certain acceptable investments with: (i) a maximum maturity; (ii) a maximum concentration and diversification; and (iii) a minimum acceptable credit quality. At this time, we believe we have minimal liquidity risk associated with the short-term investments included in our portfolio.

Long-Term Debt. The fair value of our 2010 Convertible Notes is exposed to market risk.  We do not carry the 2010 Convertible Notes at fair value but present the fair value for disclosure purposes (see Note 2 to our Financial Statements).  Generally, the fair value of the 2010 Convertible Notes is impacted by changes in interest rates and changes in the price and volatility of our common stock.  As of December 31, 2015, the fair value of the 2010 Convertible Notes was estimated at $237.9 million using quoted market prices.

Foreign Currency Exchange Rate Risk

Due to foreign operations around the world, our balance sheet and income statement are exposed to foreign currency exchange risk due to the fluctuations in the value of currencies in which we conduct business. While we attempt to maximize natural hedges by incurring expenses in the same currency in which we contract revenue, the related expenses for that revenue could be in one or more differing currencies than the revenue stream.

37

During the year ended December 31, 2015, we generated approximately 88% of our revenues in U.S. dollars. We expect that, in the foreseeable future, we will continue to generate a very large percentage of our revenues in U.S. dollars.

As of December 31, 2015 and 2014, the carrying amounts of our monetary assets and monetary liabilities on the books of our non-U.S. subsidiaries in currencies denominated in a currency other than the functional currency of those non-U.S. subsidiaries are as follows (in thousands, in U.S. dollar equivalents):

A hypothetical adverse change of 10% in the December 31, 2015 exchange rates would not have had a material impact upon our results of operations.

Management’s Report on Internal Control Over Financial Reporting

Management of CSG Systems International, Inc. and subsidiaries (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) or 15d-15(f) under the Securities Exchange Act of 1934, as amended. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures that:

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2015. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013).

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

CSG Systems International, Inc.:

We have audited CSG Systems International, Inc.’s (the Company) internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). CSG Systems International Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, CSG Systems International, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of CSG Systems International, Inc. and subsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2015, and our report dated February 26, 2016 expressed an unqualified opinion on those consolidated financial statements.

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).

We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of CSG Systems International, Inc. and subsidiaries as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles.
