ManTech International
Annual Report 2014

Plain-text annual report

To Our Shareholders For more than 46 years, ManTech has provided advanced technological services to the United States government, staying close to our customers and anticipating their technology needs, hiring highly talented professionals to propel us into the future, and acquiring companies with proven capabilities. We are now applying the lessons learned in areas such as defense, intelligence, and law enforcement to help the private sector protect networks and leverage critical information. We dedicate ourselves to our customers’ missions and act as a trusted partner helping our customers stay ahead of technology, gain efficiencies, and cut costs. ManTech supports more than 50 different government agencies under 1,100 active contracts through 2 operating groups: • Our Mission Solutions & Services (MSS) Group, led by Dan Keefe, provides business support to the Department of Defense (DoD), federal healthcare, homeland security, and civilian agencies. • Our Mission, Cyber, & Intelligence Solutions (MCIS) Group, led by Bill Varner, provides full-spectrum solutions across the cyber domain and offers misssion-critical solutions to intelligence customers. In addition, our emerging ManTech Commercial Services business unit leverages its relationship with global technology leaders SAP, Hadoop, and others, along with ManTech’s expertise in supply chain, big data, and security services for our commercial customers. 2014 RESULTS AND ACCOMPLISHMENTS ManTech’s revenue declined in 2014 as operational requirements in Afghanistan diminished, but the pace is abating as we are nearing a turning point in the market. Consistent with that view, we showed improved awards and excellent cash flow, and our operating margins increased during the year. In addition, we strengthened our overall competitive position by bolstering our capabilities in the growth markets of healthcare and homeland security, investing aggressively in business development, and demonstrating a strong commitment to our customers. Strengthened Position in Healthcare Beginning in 2012, ManTech made a strategic commitment to the federal healthcare market, and, in 2014, we took major strides toward becoming one of the market leaders. With the acquisition of 7Delta, Inc., one of the largest healthcare IT contractors for the Department of Veterans Affairs (VA), ManTech now has strong capability and presence across the entire spectrum of federal healthcare. The VA faces daunting challenges, and the country is committed to caring for our veterans. The VA will get significant new funding, and ManTech is well positioned to respond. Soon after we completed the acquisition, the VA awarded 7Delta its largest award ever ($48 million) to deliver a cloud computing solution that provides computing, storage, and other services on demand, including access to a suite of secure, scalable, and flexible IT infrastructure services. Working on next- generation solutions for the VA positions ManTech well for the future. Accelerated Growth Into Homeland Security We also acquired Allied Technology Group (ATG) as a platform for expanding our presence at the Department of Homeland Security (DHS). MSS has key contracts in training and systems engineering for Customs and Border Protection, and MCIS has an ManTech International Corporation 2014 Annual Report In February, the President forwarded his government FY16 budget request to Congress. The proposed budget recognizes the global security threats and emphasizes many missions where ManTech provides critical support. The total base DoD budget request is $534 billion, which is an almost 8% increase from the FY15 final budget. Within the budget, there are strong increases for operations and maintenance, IT, and cyber. We do not yet know how the new Republican Congress will work with the President and a new Secretary of Defense. What is clear is that the leaders of the House and Senate Armed Services Committees support an expanded defense budget. I expect that we will get some relief and that the days of further reductions in annual defense spending are behind us. If so, we would see stronger and more certain budgets, greater award flow, and a more rapid pick-up in the government services market. With the market poised to rebound, companies that have invested smartly will be the ones who prosper. We believe that the investments that we made in 2014 will help drive growth as we move through this year. Growth will come from proposals we have submitted or will submit soon, including solutions that we have built with our R&D investments. We will also use our balance sheet to fund our growth. Last year, we paid off a $200 million high- yield debt and invested all of our free cash flow in two acquisitions. With stability returning to our market, the acquisition environment is more active. At year’s end, we had $24 million in net cash and an untapped $500 million credit line with Bank of America, which places us in a strong position to make more acquisitions to grow the company, as we have done during the past four decades at ManTech. George J. Pedersen Chairman of the Board and CEO increasing presence with DHS cyber security. ATG adds presence at the Coast Guard and a strong portfolio of contracts that opens a $33 billion sales channel across DHS in IT and engineering support. ManTech is well positioned to help DHS perform its growing cyber mission, secure the nation’s borders, and keep America safe. Invested in Business Development During 2014, we made significant investments to set up growth in 2015 and beyond. We hired new business development leads for both groups and added solution architects to drive innovative solutions in our proposals. We also increased our investments in internal research and development (R&D) in cyber, mobility, and insider threat capabilities. Together, these investments enable us to target larger, more complex efforts. As a result, we submitted $6.8 billion in proposals in 2014, a 61% increase compared to 2013. Going into the year, ManTech has $4.6 billion in pending awards, including many in excess of $100 million. Demonstrated Commitment to Customers Commitment to customers is a bedrock value of ManTech. That commitment extends around the globe, even if that means being forward-deployed in the inhospitable environment and climate of Afghanistan. That commitment is recognized by customers across the federal government. In 2014, NASA’s Jet Propulsion Laboratory (JPL) honored ManTech with its Small Business Industry Awards Large Prime Contractor of the Year award for our use of small businesses and superior performance managing risks. For JPL, we consistently provided top-rated services, including circuit and systems engineering; space and mission environments modeling, simulation, and analysis; environmental requirements development and test engineering; systems safety quality and parts engineering; and IT services. POISED FOR GROWTH To begin 2015, the government passed an omnibus bill to fund the defense department and almost all other federal agencies through the end of the current fiscal year, September 30, 2015. This bill resolved much of the procurement uncertainty that comes with continuing resolutions. Our customers are taking advantage of this bill and moving forward with their acquisition strategies. 1 1 ManTech Surges in Healthcare Market ManTech is a top player in the growing federal healthcare market—one of a handful of technology companies driving innovation in health information technology. With the integration of Evolvent, ALTA Systems, and 7Delta, Inc., into ManTech now complete, ManTech Health is well positioned to deliver proven solutions for the most complex health IT challenges facing the Departments of Defense (DoD), Veteran Affairs (VA), and Health and Human Services (HHS). Under the new leadership of Stephen J. Comber, former Group President of Health for SAIC and Leidos, ManTech Health is expanding the delivery of its services into other federal agencies requiring specialized health IT solutions. ManTech’s defense health expertise includes providing Health Information Exchange and interoperability solutions for the DoD; developing and maintaining the mobile Electronic Health Record software used in operational medicine for our deployed troops; supporting the DoD’s suite of medical logistics systems; and performing analysis and studies of personnel and health data to support policy and care decisions.

ManTech Health’s HHS division provides complex healthcare system solutions and domain-specific capabilities, including health information sharing and analytic solutions. ManTech masters the technology that delivers and manages responsive, efficient, and cost-effective healthcare and health coverage. We perform system development—finding new ways to deliver patient care; integrate, build, and use healthcare IT systems; and provide healthcare systems deployment and support—making health IT available and accessible enterprise-wide. ManTech Health’s VA services division is a leading provider of innovative technology solutions. Our core services for the VA include health IT, program and project management, IT and process analysis, software engineering, operations management and support, enterprise architecture, business process mapping and analysis, and information security. Our VA services organization has a long, successful history of supporting the VA and other federal agencies on large and mission-critical program IT support services projects. ManTech Health supports mission- critical programs, including Veterans Relationship Management (VRM) Technical Integration Services; Cloud Services for Mobile Device Management and Application Environments (MDM/MAE); Standards and Terminology Services (STS); Virtual Training Campus; Virtual Lifetime Electronic Record (VLER); Veterans Benefits Management System (VBMS); and numerous projects supporting the VA’s VistA healthcare management information system. Like most specialized sectors, healthcare has its own special needs and challenges. The proper application of technology can make healthcare more secure, efficient, and affordable. Our efforts help doctors, administrators, and patients communicate better; we help provide our veterans and service members with the care they deserve. ManTech Health will always focus on supporting the immediate needs of its clients—emphasizing cost reduction and improving access to and quality of care for the patient. 2 Ma ManTech International Corporation 2014 Annual Report ManTech Advances Webb Telescope Mission ManTech’s NeXolve subsidiary’s heat shield for the James Webb Space Telescope (JWST)—known as the Sunshield—hit a major milestone in 2014 when its first layer cleared initial testing and fully entered production. NeXolve designed and manufactures the Sunshield as a subcontractor to Northrop Grumman on the JWST project. The Sunshield is tasked with protecting the JWST’s instruments from the sun’s debilitating heat so that the telescope can peer into the darkness for long periods at extremely low-operating temperatures. The five-layer structure uses Kapton® (Kapton is a registered mark of E. I. du Pont de Nemours and Company), a proprietary film that is thinner than a human hair and has a reflective metallic coating. It can unfold when on the station to a size about as large as a tennis court and will allow less than one millionth of the sun’s energy to penetrate the instruments. NeXolve began manufacturing the first flight layers last year after completing the Sunshield’s development work. The first flight layer completed testing last December. The remaining four layers are now in various stages of construction and will be completed in the next year and a half. After assembly, the ManTech team deployed the layer at its Huntsville, Alabama, facility to verify its three-dimensional shape. Using multiple laser systems, a team of engineers compared the measurements to complex analytical computer models to verify that the layer was built to the exact specifications. Each layer of the Sunshield system must maintain a unique, complex shape on-orbit to sustain the optimum environment for the telescope; each layer is composed of at least 55 gores, or individual pieces of Kapton. The first layer will face the sun and withstand the hottest temperatures. The fifth layer will be the farthest from the sun, face the telescope and instruments, and be the coolest. JWST Sunshield Successor to the Hubble Space Telescope, the JWST is the National Aeronautics and Space Administration’s (NASA) largest science mission. It will be the most powerful space telescope ever built—the world’s next- generation space observatory. It will help us observe the most distant objects in the universe, provide images of the first galaxies ever formed, and study planets orbiting distant stars. Named for NASA’s second administrator, it will provide scientists with the earliest view of the formation of our universe. The JWST is a joint project of NASA, the European Space Agency, and the Canadian Space Agency. 3 ManTech’s Key Business Areas: Focused on the Future ManTech has built its business over the past 46 years by anticipating the government’s needs and leading the development of technology that serves the American people and helps keep the nation safe.

ManTech employees use their experience, expertise, and dedication to help overcome those challenges. With more than 7,100 employees located around the world, ManTech solves today’s complex problems for our government, military, space, intelligence, and security communities. Our employees set us apart. Approximately 70% of ManTech employees hold security clearances. Our employees work hard to meet customers’ needs because the stakes are high. We are entrusted with the nation’s most sensitive technology needs in national security, healthcare, cyber, law enforcement, business and citizen services, defense, diplomacy, homeland security, and intelligence. We have to give our best. Veterans Veterans and those with military backgrounds are essential to ManTech and its work for the military, intelligence, and other government agencies. About half of our employees are veterans or have a military background. We believe veterans bring important qualities to the job—like commitment, integrity, drive, and spirit of service. We continue to be an employer of choice for veterans in 2014 and will continue to hire those who have served our country. “Fifty percent of our employees have a military background. The soldier of today is among the most sophisticated warriors the nation has ever had. The technology that they operate and utilize in their missions requires a level of knowledge and training beyond earlier times. Service members also have qualities that we need in the workplace—qualities like responsibility, dedication to mission, perseverance, integrity, teamwork, and of course, leadership. We can teach skills on the job or in a classroom, but character is harder to come by.” - George J. Pedersen Founder, Chairman, and CEO ManTech was honored in 2014 for its veteran hiring programs and support for military families. • ManTech has made G.I. Jobs magazine’s list of the nation’s most military-friendly companies every year since 2006.

We are experts in technology, and we apply our knowledge of different technologies to manage and protect information, support and maintain critical systems, and develop integrated systems to handle complex needs. With more than 45 years of experience in technology, we have earned our stripes in the challenging world of national security, starting with a single U.S. Navy contract and skillfully adapting to changing conditions. Today, we support more than 50 different government agencies under approximately 1,100 current contracts, and we have been entrusted with some of the most sensitive technology needs of our government. Our emerging commercial business includes proprietary cyber security products and integration services for global technology leaders in big data. As a multi-billion-dollar public Company, we apply our knowledge to national security, cyber, healthcare, law enforcement, business and citizen services, as well as to defense, diplomacy, homeland security and intelligence. ManTech was founded in 1968 as a New Jersey corporation and was reincorporated as a Delaware corporation in January 2002, just prior to our Initial Public Offering (IPO) in February 2002. We have grown substantially since going public, from revenues of $0.43 billion at the end of 2001 to revenues of $1.77 billion in 2014. At December 31, 2014, we had approximately 7,100 employees. For additional financial information, see Item 8 “Financial Statements and Supplemental Data.” 3 Industry Background Our primary customer is the U.S. government, the largest consumer of services and solutions in the United States. In government fiscal year (FY) 2014, the U.S. government obligated about $282 billion on contracted services. Our principal focus is on national security and homeland defense customers. The Department of Defense (DoD) is the largest purchaser of services and solutions in the U.S. government. With a government FY 2015 budget of $554 billion, the DoD accounts for approximately 50% of the total discretionary budget. After a decade of uninterrupted growth, federal spending came under pressure in recent years given mounting levels of debt. Moreover, contentiousness in Congress created uncertainty about funding levels, leading to a government shutdown in 2013, and delays in contract awards throughout most of 2014. The market environment is beginning to show signs of improvement. In December of 2014, Congress passed an omnibus funding bill for FY 2015 covering all agencies other than the Department of Homeland Security (DHS), which is funded by a continuing resolution (CR) through February 2015. This bill increases the base defense budget $3.3 billion above the enacted FY 2014 level. Aside from the uncertainty for DHS, these developments are beginning to provide our customers with the visibility necessary to develop and actively execute spending plans. Customers are now making funding and award decisions, which is a positive development for our industry. During 2014, the government continued to implement policies that adversely impact the government services industry. Chief among these was a continued focus on lowest price offers in proposal evaluations among our customers, as well as an increasing emphasis on making awards to small businesses. We expect that many of our customers will continue to factor price over the strength of technical solution in 2015. We expect government funding priorities will continue to evolve as we exit Afghanistan. FY 2014 demonstrated the importance of preserving defense funding as major global threats, including the Islamic State in the Middle East, Russian support of separatists in Ukraine, continued instability in Syria and Iraq and the Ebola outbreak in West Africa, caused serious concern within the Administration and among Members of Congress. As a result, we believe that the U.S. government's spending will remain robust in key areas for which ManTech is well positioned, including national and homeland security programs, cyber security, sophisticated intelligence gathering and information sharing activities required in a dangerous world, and implementation of new healthcare systems and policies. Also, the government is actively looking for secure cloud-based solutions and data center consolidation to save money as well as systems integration and interoperability to enable better coordination and communication within and among agencies and departments. We believe we are also well positioned in these growth markets. Our Strategy We aspire to be our customers' most trusted industry partner, integral to their success. We are a mission-driven Company that is valued by our customers, employees, teammates and investors as the premier provider of technology and engineering services and solutions to the U.S. government market. As industry returns to growth, our strategy to capitalize on the improving market dynamics is comprised of the following: • Invest in Growth Opportunities We maintain an enviable position with our customers. Since our founding in 1968, we have focused on providing technology- based solutions and services for mission-critical national security programs. We have several long standing customer relationships; many of our early customers remain our customers today. Because our personnel work in close proximity to our customers, we understand their requirements and are often able to enhance their operations by rapidly identifying and developing solutions for customer-specific requirements. In addition, in 2014, we derived 89% of our revenues as a prime contractor. As a prime, we are able to enhance the relationship with our customers, ensure overall program success, foresee emerging requirements and manage project resources. Our more than 1,100 current contracts, including large Indefinite Quantity/Indefinite Delivery (ID/IQ) vehicles, allow us to compete for work across a wide variety of customers and service offerings. To leverage this strong competitive position, we are investing in growth opportunities by increasing our business development and bid and proposal spending with a focus on awards in excess of $100 million. During 2014, we submitted more than $6.8 billion in proposals. We also added key solutions architects that enable us to build compelling solutions for large opportunities. 4 In addition, in 2014 we increased our research and development spending to create technology discriminators and differentiated solutions. As part of this initiative, we are investing in taking our capabilities to new customers. Our emerging Commercial Services business unit leverages its relationship with global technology leaders, including Hortonworks, Saffron Technology, and SAP, along with ManTech's core capabilities and industry expertise in big data, security services and supply chain for our commercial customers. ManTech Cyber Solutions International (MCSI) delivers advanced cyber security and information security products to the commercial and federal marketplace. • Wisely Use Our Strong Balance Sheet Our market, business model and financial discipline enable us to generate substantial cash to accelerate our growth and enhance shareholder returns. During FY 2014, we generated $126.9 million in operating cash flow, and as of December 31, 2014, the Company had $24 million in cash and cash equivalents and no debt. During 2014, we paid off our $200 million high-yield debt and we amended and restated our $500 million revolving credit facility, which now has a maturity date of June 13, 2019. The new credit agreement enhances the Company's strong capital position and financial flexibility, providing an increased ability to target high-growth areas organically and through strategic acquisitions. We plan to advance our internal growth by selectively pursuing strategic acquisitions that can cost-effectively broaden our domain expertise and service offerings and establish relationships with new customers. We have successfully acquired 22 businesses since our IPO in February 2002, and in 2014, we completed acquisitions to strengthen our position in federal health care information technology (IT) and homeland security. We will continue to seek out new growth areas. In particular, we intend to focus on providing new or improved solutions in cyber security, information assurance, insider threat detection, enterprise IT and health IT. In addition, we believe that it is important to return some of the cash generated by the business to shareholders as part of a balance cash deployment program. In 2014, we paid dividends of $31.3 million. Given the year-end stock price, the annual dividend yield was 3%. • Enhance our Ability to Deliver Services Efficiently Our customers are increasingly awarding work to service providers who can provide mission-critical services most efficiently. ManTech has always maintained a very competitive cost structure so we are well-positioned in the marketplace and offer a strong value proposition to our customers. We will continue our focus on being cost-competitive and look for ways to create additional efficiencies in delivering our services. We invested in systems enhancements designed to improve efficiency in our infrastructure and processes, to provide management and customers increased visibility into programs, and to support a wider set of IT offerings. • Manage the Drawdown in Afghanistan ManTech has proudly supported the U.S. military in Iraq and Afghanistan over the past decade, reaching peak levels of more than $1.0 billion in annual revenues and approximately 2,000 people in theater. As the military concludes these campaigns, our support has diminished. In 2014, in-theater support represented approximately $198 million in revenues, and we ended the year with approximately 300 people in theater. We will continue to provide unfailing support to vital missions and be ready to reconstitute the capability should the need arise. 5 Our Solutions and Services We combine deep domain understanding and technical capability to deliver comprehensive IT, systems engineering and other services and solutions, primarily in support of mission critical national security programs for the intelligence community; DoD; and the healthcare and space communities. We deploy our broad set of services in custom combinations to best address the requirements of our customers' long-term programs. The following solution sets are aligned with the long-term needs of our customers: • Cyber; • Software and Systems Development; • Enterprise Information Technology; • Multi-Discipline Intelligence; Program Protection and Mission Assurance; • • Systems Engineering; • Test and Evaluation (T&E); • Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR); • Training; • Global Logistics and Supply Chain Management; and • Management Consulting. Cyber Ubiquitous security challenges threaten not just traditional IT, but also national security systems; embedded electronics on ground, sea and aerospace platforms; classified and law enforcement networks and systems; and systems providing critical civilian services, including healthcare. Our security experts tackle the most challenging cyber security problems facing the nation, such as identifying and neutralizing external cyber attacks, engineering tailored defensive security solutions and controls, managing cyber security operations centers (CSOCs), developing robust insider threat detection programs and creating enterprise vulnerability management programs. We have provided computer network operations support to important national security customers for more than a decade, working across the three domains of computer network attack, defense and exploitation. We provide comprehensive cyber warfare and cyber defense security solutions and services to the DoD, agencies in the intelligence community, Department of State, Department of Justice and other federal agencies, as well as commercial clients. We operate 24/7 CSOCs for several key government customers, including the Department of Justice, Federal Bureau of Investigations (FBI), Executive Office of U.S. Attorneys and several intelligence community agencies. We are also trusted partners in the area of information assurance (IA). Our understanding of IT security guidance and policy allows us to assist our customers in ensuring their programs are protected in accordance with that policy and in developing mitigation strategies to reduce the risks of cyber threats. Our vulnerability assessment and penetration testing capabilities allow us to emulate threats to information, whether from wired or wireless networks, software applications or through social engineering. If a customer is unfortunate enough to have experienced a compromise, we can deploy our incident response team, comprised in part of former cyber federal law enforcement agents, around the world to assist them. We operate the DoD IA (Cyber) Range for the Defense Information Systems Agency (DISA) and the Office of the Secretary of Defense (OSD) under the operational control of the Marine Corps. In unclassified and classified venues, we provide a full range of services to train cyber warriors; test programs, systems and products; and exercise cyber warfighters and system operations/ procedures in a low risk/highly realistic environment to prepare for cyber warfare. We develop operationally realistic, scalable and rapidly configurable environments that replicate or emulate the customer's environment. Our DoD IA (Cyber) Range customer interface includes: Cyber Range infrastructure design and hosting; Cyber Range operations development; Cyber exercise support; Immersive Cyber environments; and real and virtual Red Team activities for providing offensive challenges to cyber defenders. Our commercial cyber security business builds upon our skills and capabilities acquired in support of federal agencies. By offering a full service cyber solutions capability for the commercial market, we are able to provide ManTech services which augment our commercial product line, and likewise offer those cyber security products to our federal customers. We currently provide forensics support, advanced persistent threat detection, incident response, malware analysis, threat intelligence and threat management capability to clients in the financial, energy, retail and U.S. critical infrastructure sectors. Our solutions also support unique mission areas such as computer forensics, cyber threat analysis, computer crimes investigations, security operations center management and specialized cyber training. We perform advanced services in the areas of data mining analysis, atypical data recovery techniques and data extraction. For example, in support of a customer, we develop and staff a national level computer forensic laboratory and provide a broad spectrum of subject matter expertise, including reverse 6 engineering and code analysis; forensic signature creation, detection and analysis; damaged media recovery; hidden data processing; protected data processing; forensic software development; and custom training development and implementation. Software and Systems Development We develop, modify and maintain software solutions and complex systems that link together different computing systems and software applications to act as a coordinated whole. This solution set includes a broad array of development activities across the full lifecycle, including requirements analysis, identification of need, planning, design, implementation, integration, enhancement, testing, documentation, deployment and maintenance. Activities cross a variety of development methodologies, including waterfall, prototype model, incremental, iterative, V-Model, Spiral, Agile and Scrum. Supporting disciplines include configuration management, documentation, software quality assurance, embedded systems, project management and user experience. We develop software solutions and systems across many domains and applications. Modern warfare (whether on a physical or cyber battlefield) requires the warfighter to assess and use information from multiple sources quickly and appropriately. Our experienced software engineers and developers design and support the real-time software applications that cyber security programs, C4ISR systems, and other complex defense and weapons systems rely on to function as designed. As the lead systems integrator for the Marine Corps, ManTech uses its Agile methodology to reduce defects, re-work and overhead costs, resulting in rapid, cost- effective systems integration. We implement software development solutions in the federal healthcare market. Our technology solutions empower patients and providers with better, richer, and more timely data, care coordination solutions, and imaging management capabilities and all of our technology solutions are built on interoperable platforms to new national standards. For example, ManTech designed and developed the Healthcare Artifact and Image Management Solution (HAIMS) program that provides awareness of and access to patient artifacts and images (A&I) around the world. HAIMS ingests A&I along with metadata information from repositories worldwide, providing global access to military clinicians for search and retrieval of this data. This solution provides clinicians a logical extension to the current electronic health record and newer web-based user interface platforms so that the presence of A&I will be made apparent in the proper clinical context, including associated encounters, radiological and other specialty reports, and dental documentation. Enterprise IT IT plays an increasingly central role in the missions of our defense, intelligence and federal civilian customers, and as a result, is an important part of many of our solution areas. We develop, implement and sustain solutions that leverage technology across an enterprise to deliver a service to improve mission performance and lower costs for our government customers. Solutions typically involve hardware and software to support the core technology infrastructure, such as data centers, cloud services, e-mail or desktop computing. Specific applications include IT service management, help desk, data center consolidation, enterprise architecture, mobile computing and device management, network operations and infrastructure, virtualization/cloud computing, network and database administration, enterprise systems development and management, and Infrastructure as a Service (IaaS). The backbone of our global capabilities is a comprehensive ISO 9001:2000-certified management and control system designed to provide best value for our customers and to lower the total cost of ownership across the systems' lifecycles. We leverage our strong engineering discipline to aid our customers in moving their IT enterprise infrastructure and applications from disparate instances into cloud and virtual offerings. The migration towards customer private secure cloud architectures is compelling because it enables our customers to integrate their global IT infrastructure optimally, while still providing the geo- specific requirements where necessary. For a DoD customer we are consolidating multiple instances of stove-piped applications onto a single utility cloud backbone, allowing these legacy applications to continue supporting their mission while lowering the overall operations cost. We have spearheaded the development of cloud architecture for the U.S. Army's Distributed Common Ground Systems (DCGS-A) and have provided experienced technical personnel, extensive corporate knowledge and battle-tested system solutions. We support the sustainment of regional and edge clouds today and will continue to field and test innovative cloud concepts and technologies and help the government develop and use them in the future. We also support the FBI's Criminal Justice Information Services (CJIS), where we are providing operations and maintenance support to one of the world's largest data centers. FBI CJIS equips the law enforcement, national security and intelligence community with the criminal justice information they need to protect the United States while preserving civil liberties. ManTech operates, maintains, refreshes and enhances FBI CJIS IT systems required to process and share mission-critical information for members of the law enforcement community in the United States and abroad. ManTech is sustaining systems that support millions of requests each day, including when police check vehicle license plates or look for a fingerprint match against the largest biometrics database in the world. The mission-critical systems we support must be operational and available 24/7; we understand that the 7 impact to police officers, FBI agents, customs agents and government agencies nationwide would be significant, even life- threatening, if the systems were to go down. Specific functions supported include IT system operations and maintenance, database administration, cyber security and hardware and data center support. One area of particular emphasis is the creation of a seamless medical record across the DoD and the Department of Veterans Affairs (VA). The Bidirectional Health Information Exchange (BHIE) has been the primary interoperability platform between the DoD and the VA for many years. Used daily by thousands of providers, it is one of the world's most comprehensive and highest volume Health Information Exchanges (HIEs). ManTech helped migrate the legacy BHIE system toward modern health IT standards by adopting the Nationwide Health Information Network and associated standards wherever possible. The Virtual Lifetime Electronic Record (VLER) effort, which is being carried out in conjunction with the BHIE upgrade project, enables sharing not only between DoD and VA, but also between the government and civilian provider networks and local HIEs. ManTech has developed VLER-Health on behalf of the DoD in conjunction with its work to upgrade the BHIE. Functional domain content for BHIE and VLER-Health overlaps significantly; ManTech is integrating these two projects to share data-access methods and use DoD's Nationwide Health Information Network gateway. ManTech provides the DISA with a unified and secure situational-awareness management environment. ManTech supports the integration of DISA's Operations Support System and its Global NetOps Information Sharing Environment. This enhancement of DISA's NetOps infrastructure will improve the quality and timeliness of collaborative decision-making regarding the employment, protection and defense of the Global Information Grid. Multi-Discipline Intelligence We provide specialized IT solutions and mission support services to national intelligence agencies and other classified customers. Specific solutions include support to strategic and tactical intelligence systems, networks and facilities; development and integration of collection and analysis systems and techniques; and support to the development and application of analytical techniques to counterintelligence, Human-Intelligence operations/training and counterterrorist operations. ManTech provides SIGINT collection, analysis and dissemination, intelligence analysis and linguistics, and computer network operations, including monitoring and protection, cyber operations support, and collaboration tools and analysis to support the intelligence lifecycle. We develop, integrate and maintain advanced signal processing systems to support classified programs and facilities that collect and process intelligence. We provide embedded counterterrorism and counterintelligence analytical expertise to the U.S. Southern Command to skillfully research, corroborate and determine key nodes in threat organizations. The tailored intelligence products produced by our analysts directly contribute to U.S. national security objectives and aid senior decision makers at U.S. Southern Command to develop and carry out effective defense and policy strategies throughout Latin America and the Caribbean. Program Protection and Mission Assurance Highly-classified programs, including intelligence operations and military programs, require secrecy management and security infrastructure services from a trusted and experienced provider. These services can include vulnerability assessment, insider threat protection, exposure analysis, secrecy architecture design, security policy development and implementation, lifecycle acquisition program security, operations security, information assurance, Anti-Tamper, Export Compliance support, foreign disclosure, system security engineering, security awareness and training, comprehensive security support services and technical certification and accreditation services. We provide integrated security support for a number of programs, including the Joint Strike Fighter (JSF) Program, which presents one of the most complex security problem sets of any weapon system in our nation's history due to the numerous highly classified technologies incorporated in its design and international content in both its development and its usage. As part of our program protection support, we provided network architecture planning and implementation services and systems engineering services within secure environments requiring the application of multi-level security policies across the enterprise. Secure enterprise-wide network infrastructures and components include local area network/wide area network architectures, messaging architectures, network management solutions, directory services architecture and web hosting. For example, we developed a state-of-the-art analytic environment that provides access to regional, national and international information with appropriate security level access controls, providing direct operational support to time-sensitive counterterrorism activities in support of an intelligence community customer. In addition, ManTech provides comprehensive mission assurance in the development, acquisition, manufacturing, testing, integration and site support of mission critical systems to include space lift and satellite systems. We provide full spectrum security; reliability, maintainability and availability engineering; systems-safety engineering; hardware and software quality engineering; 8 software assurance practices; and lifecycle support. ManTech personnel develop and review mission assurance and safety requirements and carry out design reviews and analysis, safety analysis, requirements verification, test readiness reviews, integration and test support, and operations support to ensure that those requirements are designed into systems. ManTech provides comprehensive safety, reliability, quality assurance and engineering support to NASA Flight Projects and the U.S. Air Force Space and Missile Systems Center. ManTech specialists troubleshoot safety issues during launch, on orbit, or in flight, and our work has influenced redesign of components and processes to improve safety. Our independent assessment teams solve problems independently for our customers and improve complex procedures and operations. ManTech's metrology teams expertly calibrate the most sophisticated instruments to ensure proper measurement of data and conditions. Some of our specific launch-safety services include basic assessments; specialized risk programs; databases; evaluation of potential impacts to facilities, operations and workers; and other activities critical to both the vehicle and the mission. Systems Engineering Since 1968, ManTech's scientists and engineers have provided disciplined systems engineering support, including process development and implementation; mission analysis and architecture; requirements analysis, development and management; tactical systems development and integration; modeling and simulation; test and evaluation/Independent Validation & Verification (IV&V); concepts of operations, risk management and reliability and maintainability. We currently provide systems engineering support to a wide range of customers, including programs and offices within the DHS, DoD and intelligence community. For example, we perform comprehensive systems engineering services to analyze, develop and integrate solutions for U.S. Navy hardware and software requirements across subsurface, surface, ground, air and space domains; provide acquisition and program management support for the DHS's Customs and Border Protection (CBP) Office of Technology, Innovation and Acquisition; and support current and future space launch operations for the U.S. Air Force Launch and Range Systems Wing with systems engineering and integration services. We also provide scientific, engineering and technical support services to the Department of Energy's SunShot Initiative, which aims to reduce by 75% the cost of utility-scale electricity at the grid by the year 2020. Our proprietary systems engineering toolset, the ManTech Enterprise Framework, provides a regimented and interdisciplinary approach to transition from a stated need to an operationally effective and suitable system, service or capability. Based in “Systems Thinking,” the framework is an overarching and proven process that integrates the full spectrum of project management, systems engineering and acquisition practices necessary to effectively manage a project or system over its lifecycle. Through it, we address a full 360-degree perspective of a program, including disciplines of system, software, hardware, acoustics, communications, reliability, safety and test engineering, as well as modeling, simulation and analysis. Our long-term commitment to the systems engineering discipline is exemplified by our achievement of our Capability Maturity Model® Integration (CMMI) Level 3 rating for Software and Systems Engineering. Test and Evaluation ManTech is a leading provider of Test and Evaluation (T&E) services to a wide range of defense, intelligence, homeland security and space customers. We provide comprehensive T&E services for tactical and strategic C4ISR systems and National Security Systems and Information Technology Systems (NSS/ITS). Our knowledge of DoD testing and evaluation policies and procedures ensures that technical solutions are complete and align with test requirements. Our T&E services are tightly linked with our systems engineering capabilities and include specific competencies in test engineering, preparation and planning; modeling and simulation; test range operations and management; systems and cyber vulnerability; and IV&V. Employing a technical staff with a wide range of practical experience and education, we provide our clients with the right skill sets to support and perform operational and developmental tests. ManTech's developmental T&E professionals verify systems for all types of federal acquisition programs, from planning through reporting phases. Our test engineers develop requirements and assess the technical maturity of systems before those systems are designated as programs of record. We monitor and review vendor testing to verify system performance against the technical specifications, and we plan and conduct developmental testing to ensure that systems are ready for operational testing. Our operational T&E professionals plan and execute a wide array of operational programs to ensure that systems meet requirements for effectiveness, suitability, interoperability and survivability in operational environments. ManTech's test engineers plan and conduct integrated testing to streamline cost, schedule and risk during operational testing. Our approach minimizes "surprise discovery" during Initial Operational T&E (IOT&E). 9 We test complex and mission-critical hardware and software systems used by the Army, Navy and Marine Corps, with many of these customer relationships spanning more than three decades. We have played key roles in improving the performance, reliability, maintainability, supportability and weapons effectiveness of all Navy in-service rotary and fixed wing platforms and their associated systems and ordnance. Likewise, we maintain a facility to support Marine Corps intelligence systems research and development, providing the T&E to ensure these systems meet specified requirements for Marines in the field. We perform independent tests to certify that new or upgraded systems operate in accordance with design requirements and interoperate with legacy systems. For example, ManTech has installed, operated and maintained a large and complex joint test environment for the Joint Interoperability Test Command (JITC) within DISA. ManTech has provided continuous technical and operational support to DISA's JITC for more than 20 years. In that time, it has established itself as a joint testing center of excellence. ManTech performs a broad range of services associated with the Command's overall mission. These services include joint interoperability certification, operational T&E and standards conformance testing on tactical and strategic C41 systems as well as NSS/ITS in support of military operations. We have also performed certification services for aircraft weapon systems in support of U.S. Naval Air Systems Command programs. Additionally, we are the prime contractor supporting the U.S. Army's Electronic Proving Ground at Fort Huachuca, AZ.

Embedded with deployed combat units, our technicians install, integrate and maintain secure satellite communications, IT systems, and electronics equipment. We quickly deploy ManTech personnel and equipment, worldwide, through 23 Army-owned support centers that we operate in six countries. 11 Management Consulting We help organizations improve their performance by providing objective advice, specialized expertise and access to industry "best practices" in the form of organizational change management assistance, process analysis, technology implementation, strategy development or operational improvement services. Specific applications include environmental, range and sustainability services; healthcare analytics, such as population health analyses; and "big data" solutions to drive better decision-making and controls. Our management consulting solutions include a focus on transforming health care by analyzing, designing, implementing, and evaluating information and communication systems that enhance individual and population health outcomes, improve patient care and strengthen the clinician-patient relationship. ManTech collaborates with clinicians in the development of health informatics tools that promote safe, efficient, effective, timely, patient-centered and equitable patient care. We also collect, manage and analyze large amounts of demographic and clinical data to help our customers prevent or treat disease to improve the health and quality of life in communities across the U.S. and worldwide. ManTech is also a leader in the fields of environmental, range and sustainability planning, regulatory compliance, biological resources and policy development. In an increasingly interconnected world with growing demands for limited resources, we provide trusted solutions that meet today's most pressing challenges while securing the future. Our multidisciplinary staff of planners, scientists, analysts and managers brings the education, experience and expertise to develop and execute comprehensive sustainability strategies and environmental compliance programs in support of government and industry. We work with our customer to manage and comply with the nation's most important environmental laws, including the National Environmental Policy Act, the Endangered Species Act and the Marine Mammal Protection Act. We also provide ocean and coastal environmental planning, coastal zone management planning, biological surveys and monitoring, bioacoustics and noise analysis, habitat restoration, invasive species management and solid-waste compliance support. For example, naval training and test ranges can require large areas and are often questioned for their potential impact on sensitive environments. In order to retain the ability to train personnel and test equipment, the Navy has developed an integrated program to assess the impact of its ranges and minimize impact on the environment, populated areas, shipping and navigation. Tactical Training Theater Assessment Program (TAP) is the Navy's comprehensive program focused on environmental planning and sustainability of training and test ranges worldwide. ManTech delivers critical planning solutions to complex environmental and regulatory challenges in order to preserve and enhance the capabilities of Navy and Marine Corps ranges. Our Customers Our primary customers are U.S. government intelligence, military, space and civilian agencies. In addition, we support some state and local governments and commercial customers. We derive most of our revenues from national security and homeland defense customers. We have successful, long-standing relationships with our customers, having supported many of them for over 45 years. Year Ended December 31, 2014 2013 2012 Percentage of Revenues from U.S. Government Customers Percentage of Revenues from National Security and Homeland Defense 98.9% 99.0% 99.2% 92.2% 95.6% 95.4% Our customers include the departments of Defense, State, Homeland Security, Health and Human Services, Veteran Affairs and Justice, including the FBI; the space communities and other U.S. government customers. To provide deep understanding of our customers' missions, we target candidates for employment who have served in the military or as civilian experts in the intelligence community and DoD, as well as those who are leading specialists in their technology disciplines. Since 2006, we have annually been ranked in the Top 10 in the nation on the G.I. Jobs Magazine Military-Friendly Employers list. Our U.S. government customers typically exercise independent contracting authority, and even offices or divisions within an agency or department may directly, or through a prime contractor, use our services as a separate customer so long as that customer has independent decision-making and contracting authority within its organization. For example, under a contract with one of the 12 Army's contracting agencies, program managers throughout the Army and from other services and defense agencies are able to purchase a wide range of our solutions. The U.S. Army Tank-Automotive Armament Command (TACOM) contract accounted for 7.5%, 19.4% and 22.2% of our revenues for the years ended December 31, 2014, 2013 and 2012, respectively. Foreign Operations We treat sales to U.S. government customers as sales within the United States regardless of where the services are performed. U.S. revenues were approximately 99.7%, 99.8% and 99.8% of our total revenues for the years ended December 31, 2014, 2013 and 2012, respectively. International revenues were approximately 0.3%, 0.2% and 0.2% of our total revenues for the years ended December 31, 2014, 2013 and 2012, respectively. Backlog At December 31, 2014, our backlog was $3.3 billion, of which $0.8 billion was funded backlog. At December 31, 2013, our backlog was $3.9 billion, of which $1.1 billion was funded backlog. The decrease in our backlog primarily reflects reduced demand on contracts related to Overseas Contingency Operations (OCO) resulting from the accelerated withdrawal from Afghanistan. We expect that approximately 38% of our total backlog will be recognized as revenues prior to December 31, 2015. We define backlog as our estimate of the remaining future revenues from existing signed contracts, assuming the exercise of all options relating to such contracts and including executed task orders issued under ID/IQ contracts. We also include an estimate of revenues for solutions that we believe we will be asked to provide in the future under the terms of ID/IQ contracts for which we have an established pattern of revenues. We define funded backlog to be the portion of backlog for which funding currently is appropriated and allocated to the contract by the purchasing agency or otherwise authorized for payment by the customer upon completion of a specified portion of work. Our funded backlog does not include the full value of our contracts because Congress often appropriates funds for a particular program or contract on a yearly or quarterly basis, even though the contract may call for performance that is expected to take a number of years. Changes in the amount of our backlog and funded backlog result from potential future revenues following the execution of new contracts or the extension of existing contracts, reductions from contracts that end or are not renewed, reductions from the early termination of contracts and adjustments to estimates for previously included contracts. Changes in the amount of our funded backlog also are affected by the funding cycles of the government. Our estimates of future revenues are inexact and the receipt and timing of any of these revenues is subject to various contingencies, many of which are beyond our control. The actual accrual of revenues on programs included in backlog and funded backlog may never occur or may change because a program schedule could change, a program could be cancelled, a contract could be modified or cancelled, an option that we have assumed would be exercised is not exercised or initial estimates regarding the amount of services that we may provide could prove to be wrong. For the same reason, we believe that period-to-period comparisons of backlog and funded backlog are not necessarily indicative of future revenues that we may receive. Patents, Trademarks, Trade Secrets and Licenses We own a limited number of patents. We also maintain a number of trademarks and service marks to identify and distinguish the goods and services we offer. While we believe protecting our patents, marks, trade secrets and vital confidential information is important, our business does not depend on the existence or protection of such intellectual property. Seasonality Our business is not seasonal. However, it is not uncommon for U.S. government agencies to award extra tasks or complete other contract actions in the weeks before the end of the U.S. government's fiscal year (which is September 30) in order to avoid the loss of unexpended fiscal year funds. Additionally, our quarterly results are impacted by the number of working days in a given quarter. There are generally fewer working days for our employees to generate revenues in the first and fourth quarters of our fiscal year. 13 Competition Our key competitors currently include divisions of large defense contractors, as well as a number of mid-size U.S. government contractors with specialized capabilities. Because of the diverse requirements of U.S. government customers and the highly competitive nature of large procurements, we frequently collaborate with these and other companies to compete for large contracts and bid against these companies in other situations. Company Information Available on the Internet Our Internet address is www.mantech.com. Through links on the Investor Relations section of our website, we make available, free of charge, our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission (SEC). Item 1A. Risk Factors Forward-Looking and Cautionary Statements Set forth below are the risks that we believe are material to our investors. You should carefully consider the following risks together with the other information contained in or incorporated by reference into this Annual Report on Form 10-K, including our consolidated financial statements and notes thereto. The risks described below are not the only risks facing us. Additional risks and uncertainties not currently known to us, or those we currently deem to be immaterial, may also materially and adversely affect our business, financial condition or results of operations. This section contains forward-looking statements. You should refer to the explanation of the qualification and limitations of forward-looking statements set forth at the beginning of this Annual Report. Risks Related to Our Business We depend on contracts with the U.S. government for substantially all of our revenues. If our relationships with the U.S. government were harmed, our business, future revenues and growth prospects could be adversely affected. We derive the vast majority of our revenues from our U.S. government customers. We expect that U.S. government contracts will continue to be the primary source of our revenues for the foreseeable future. Our business, prospects, financial condition or operating results could be materially harmed if: • We are suspended or debarred from contracting with the U.S. government or a significant government agency; • Our reputation or relationship with government agencies is impaired; or • The government ceases to do business with us, or significantly decreases the amount of business it does with us. Among the key factors in maintaining our relationships with U.S. government agencies are our performance on individual contracts and task orders, the strength of our professional reputation and the relationships of our senior management with our customers. U.S. government spending levels for programs we support may change or be delayed in a manner that adversely affects our future results and limits our growth prospects. Our business depends upon continued U.S. government expenditures on intelligence, defense and other programs that we support. These expenditures have not remained constant over time. Over the last couple years, in the face of growing national debt and long-term fiscal challenges facing the nation, spending levels for U.S. government programs generally, and in particular the U.S. defense budget, have come under pressure. Federal budget constraints may affect future levels or timing of expenditures, place pressure on operating margins in our industry, and shift expenditures to programs in areas where we do not currently provide services, thereby adversely impacting our future results of operations. A reduction in the amount of services that we are contracted to provide, or incorporation of less favorable terms in existing or future contracts, could cause an adverse impact on our business and future results of operations. 14 The failure by Congress to approve budgets on a timely basis for the federal agencies we support could delay procurement of our services and solutions and cause us to lose future revenues. On an annual basis, Congress must approve budgets that govern spending by the federal agencies that we support. In years when Congress is not able to complete its budget process before the end of the U.S. government's fiscal year on September 30, Congress typically funds government operations pursuant to a continuing resolution. A continuing resolution allows U.S. government agencies to operate at spending levels approved in the previous budget cycle. When the U.S. government operates under a continuing resolution, it may delay funding we expect to receive from customers on work we are already performing and will likely result in new initiatives being delayed or in some cases cancelled. The U.S. government's failure to complete its budget process, or to fund government operations pursuant to a continuing resolution, may result in a U.S. government shutdown, such as that which occurred during the 2013 fiscal year. We derive most of our revenues from contracts awarded through competitive bidding processes, and our revenue and profitability may be adversely impacted if we fail to compete effectively in such processes, or if there are delays as a result of our competitors' protests of contract awards that we receive. We derive a significant portion of revenues from U.S. government contracts awarded through a competitive bidding process. We do not anticipate that this will change in the foreseeable future. Our failure to compete effectively in this procurement environment would have a material adverse impact on our revenue and profitability. The competitive bidding process involves risk and significant costs to businesses operating in this environment including: • Spending substantial cost and managerial time and effort to prepare bids and proposals for contracts that may not be awarded to us, which may result in reduced profitability; • Expending resources and making financial commitments (such as procuring leased premises) and bidding on programs in advance of the completion of their design, which may result in unforeseen difficulties in execution, cost overruns, or, in the case of unsuccessful competition, the loss of committed costs. • Incurring expense and delays due to protests or challenges of contract awards made to us from unsuccessful bidders, including the risk that any such protest or challenge could result in the resubmission of bids on modified specifications, or in the termination, reduction or modification of the awarded contract, which may result in reduced profitability; • Changes in policy and goals by the government providing set-aside funds to small business, disadvantaged businesses and other socio-economic requirements in the allocation of contracts; and • Failing to accurately estimate the resources and cost structure that will be required to service any contract we are awarded. Additionally, many of our customers have increasingly focused on cost as a key component of the procurement evaluation process. This focus has increased competitive pricing pressures and resulted in a reduction to the profits we expect to earn on our U.S. government contracts. Specifically, the use by the U.S. government of a lowest price/technically acceptable standard for contract awards, may require us to decrease the margin by which we expect our bid price to exceed our costs. If we are unable to win particular contracts that are awarded through the competitive bidding process, in addition to the risk that our operating results may be adversely affected, we may be unable to operate in the market for services that are provided under those contracts for a number of years. 15 We face aggressive competition that can impact our ability to obtain contracts, and therefore affect our future revenues and growth prospects. We operate in highly competitive markets and generally encounter intense competition to win contracts, which are usually subject to competitive bidding processes. We may not be able to continue to win competitively awarded contracts at historic levels. We compete with larger companies that have greater name recognition, financial resources and larger technical staffs than we have. We also compete with smaller, more specialized companies that are able to concentrate their resources on particular areas. To remain competitive, we must provide superior service and performance on a cost-effective basis to our customers. Our competitors may be able to provide our customers with different or greater capabilities or better contract terms than we can provide, including technical qualifications, past contract experience, geographic presence, price and the availability of qualified professional personnel. In particular, increased efforts by our competitors to meet U.S. government requirements for efficiency and cost reduction may necessitate that we become more competitive with respect to price, and thereby potentially reduce our profit margins, in order to win or maintain contracts. In addition, our competitors may consolidate or establish teaming or other relationships among themselves or with third parties to increase their ability to address customers' needs. Our earnings and profitability may be adversely affected if we do not accurately estimate the expenses, time and resources necessary to satisfy some of our contractual obligations. We enter into three types of U.S. government contracts for our services: cost-reimbursable, time-and-materials and fixed- price. Our customers have increasingly procured our services under cost-reimbursable contracts, which tend to offer lower margin opportunities than other contract types. For our last three fiscal years, we derived revenues from such contracts as follows: Cost-reimbursable Fixed-price Time-and-materials Total Year Ended December 31, 2014 2013 2012 68.9% 21.1% 10.0% 100.0% 72.3% 16.8% 10.9% 100.0% 51.0% 16.2% 32.8% 100.0% Each of these types of contracts, to varying degrees, involves some risk that we could underestimate our cost of fulfilling the contract, which may reduce the profit we earn or lead to a financial loss on the contract. • Under cost-reimbursable contracts, we are reimbursed for allowable costs and paid a fee, which may be fixed or performance-based. To the extent that the actual costs incurred in performing a cost-reimbursable contract are within the contract ceiling and allowable under the terms of the contract and applicable regulations, we are entitled to reimbursement of our costs, plus a profit. However, if our costs exceed the ceiling or are not allowable under the terms of the contract or applicable regulations, we may not be able to recover those costs. In particular, there is increasing focus by the U.S. government on the extent to which contractors are able to receive reimbursement for employee compensation. • Under fixed-price contracts, we perform specific tasks for a fixed price. Compared to cost-plus contracts, fixed- price contracts generally offer higher margin opportunities, but involve greater financial risk because we bear the impact of cost overruns, which could result in increased costs and expenses. Because we assume such risk, an increase in the percentage of fixed-price contracts in our contract mix, whether caused by a shift by the U.S. government toward a preference for fixed-price contracts or otherwise, could increase the risk that we suffer losses if we underestimate the level of effort required to perform the contractual obligations. • Under time-and-material contracts, we are reimbursed for labor at negotiated hourly billing rates and for certain expenses. We assume financial risk on time-and-material contracts because we assume the risk of performing those contracts at negotiated hourly rates. Our profits could be adversely affected if our costs under any of these contracts exceed the assumptions we used in bidding for the contract. 16 Many of our U.S. government customers execute their procurement budgets through multiple award contracts under which we are required to compete for post-award orders, or for which we may not be eligible to compete, potentially limiting our ability to win new contracts and increase revenues. Budgetary pressures and reforms in the procurement process have caused many U.S. government customers to purchase goods and services through multiple award ID/IQ contracts and other multiple award and/or government wide acquisition contract vehicles. These contract vehicles require that we make sustained post-award efforts to obtain task orders under the relevant contract. There can be no assurance that we will obtain revenues or otherwise sell successfully under these contract vehicles. Our failure to compete effectively in this procurement environment could harm our operating results. U.S. government contracts contain provisions giving government customers a variety of rights that are unfavorable to us, including the ability to terminate a contract at any time for convenience. U.S. government contracts contain provisions and are subject to laws and regulations that give the government rights and remedies not typically found in commercial contracts. These provisions may allow the government to: • Terminate existing contracts for convenience, as well as for default; • Reduce orders under, or otherwise modify contracts or subcontracts; • Cancel multi-year contracts and related orders if funds for contract performance for any subsequent year become unavailable; • Decline to exercise an option to renew multi-year contracts or issue task orders in connection with multiple award contracts; • • • Suspend or debar us from doing business with the U.S. government or with a government agency; Prohibit future procurement awards with a particular agency as a result of a finding of an organizational conflict of interest based upon prior related work performed for the agency that would give a contractor an unfair advantage over competing contractors; Subject the award of contracts to protest by competitors, which may require the contracting federal agency or department to suspend our performance pending the outcome of the protest and may also result in a requirement to resubmit offers for the contract or in the termination, reduction or modification of the awarded contract; • Terminate our facility security clearances and thereby prevent us from receiving classified contracts; • Claim rights in products and systems produced by us; and • Control or prohibit the export of our products and services. If the government terminates a contract for convenience, we may recover only our incurred or committed costs, settlement expenses and profit on work completed prior to the termination. If the government terminates a contract for default, we may not even recover those amounts and instead may be liable for excess costs incurred by the government in procuring undelivered items and services from another source. If one of our government customers were to unexpectedly terminate, cancel or decline to exercise an option to renew one or more of our significant contracts or programs, our revenues and operating results would be materially harmed. 17 We may not realize as revenue the full value of our backlog, which could adversely affect our expected future revenues and growth prospects. As of December 31, 2014, our backlog was $3.3 billion, of which $0.8 billion was funded. Backlog is our estimate of the remaining future revenues from existing signed contracts, assuming the exercise of all options relating to such contracts and including executed task orders issued under ID/IQ contracts. Backlog also includes estimates of revenues for solutions that we believe we will be asked to provide in the future under the terms of ID/IQ contracts for which we have an established pattern of revenues. Our estimates are based on our experience using such vehicles and similar contracts. However, due to the U.S. government's ability to not exercise contract options, and to terminate or modify our programs and their associated contracts, we cannot assure that all, or any, of such estimated contract revenues will be recognized. Furthermore, the actual receipt of revenue from contracts included in backlog may never occur or may be delayed because: a program schedule could change or the program could be cancelled; or a contract's funding or scope could be reduced, modified, delayed or terminated early, including as a result of a lack of appropriated funds or as a result of cost cutting initiatives and other efforts to reduce U.S. government spending. Our unfunded backlog, in particular, contains management's estimate of amounts expected to be realized on unfunded contract work that may never be realized as revenues. If we fail to realize as revenues those amounts included in our backlog, our future revenues and growth prospects may be adversely affected. Acquisitions could result in operating difficulties, dilution or other adverse consequences to our business. One of our key operating strategies is to selectively pursue acquisitions. Our acquisitions strategy poses many risks, including: • As a result of an acquisition, we may need to record write-downs from future impairments of intangible assets, which could reduce our future reported earnings; • We may have difficulty retaining an acquired company's key employees or customers; • We may have difficulty integrating acquired businesses, resulting in unforeseen difficulties, such as incompatible accounting, information management or other control systems; and • Acquisitions may disrupt our business or distract our management from other responsibilities. In connection with any acquisition that we make, there may be liabilities that we fail to discover or that we inadequately assess. Acquired entities may not operate profitably or result in improved operating performance. Additionally, we may not realize anticipated synergies. If our acquisitions perform poorly, our business and financial results could be adversely affected. Goodwill represents a significant asset on our balance sheet, and changes in future business conditions could cause these investments to become impaired, requiring substantial write-downs that would reduce our operating income. As of December 31, 2014, our goodwill was $851.6 million. The amount of our recorded goodwill may substantially increase in the future as a result of any acquisitions that we make. We evaluate the recoverability of recorded goodwill amounts annually, or when evidence of potential impairment exists. Impairment analysis is based on several factors requiring judgment and the use of estimates, which are inherently uncertain and based on assumptions that may prove to be inaccurate. Additionally, material changes in our financial outlook, as well as events outside of our control, such as deteriorating market conditions for companies in our industry, may indicate a potential impairment. When there is an impairment, we are required to write down the recorded amount of goodwill, which is reflected as a charge against operating income. We recorded a non-cash goodwill impairment charge of $118.4 million for the year ended December 31, 2013. 18 If we fail to comply with complex procurement laws and regulations, we could lose business and be liable for various penalties or sanctions. We must comply with laws and regulations relating to the formation, administration and performance of U.S. government contracts. These laws and regulations affect how we conduct business with our U.S. government customers. In complying with these laws and regulations, we may incur additional costs. Non-compliance could result in the imposition of fines and penalties, including contractual damages. Among the more significant laws and regulations affecting our business are the following: • The Federal Acquisition Regulation, which comprehensively regulates the formation, administration and performance of U.S. government contracts; • The Truth in Negotiations Act, which requires certification and disclosure of all cost and pricing data in connection with contract negotiations; • The Cost Accounting Standards and Cost Principles, which impose accounting requirements that govern our right to reimbursement under certain cost-based U.S. government contracts; • Laws, regulations and executive orders restricting the use and dissemination of information classified for national security purposes and the export of certain products, services and technical data; • U.S. export controls, which apply when we engage in international work; and • The Foreign Corrupt Practices Act. Failure to comply with these laws and regulations can lead to severe penalties, both civil and criminal, and can include debarment from contracting with the U.S. government. Our contracting agency customers periodically review our compliance with procurement laws and regulations, as well as our performance under the terms of our U.S. government contracts. If a government review or investigation uncovers improper or illegal activities, we may be subject to civil or criminal penalties or administrative sanctions, including the termination of contracts, forfeiture of profits, the triggering of price reduction clauses, suspension of payments, fines and the suspension or debarment from doing business with federal government agencies. Additionally, the civil False Claims Act provides for potentially substantial civil penalties where, for example, a contractor presents a false or fraudulent claim to the government for payment or approval. Actions under the civil False Claims Act may be brought by the government or by other persons on behalf of the government (who may then share a portion of any recovery). If we fail to comply with these laws and regulations, we may also suffer harm to our reputation, which could impair our ability to win awards of contracts in the future or receive renewals of existing contracts. If we are subject to civil and criminal penalties and administrative sanctions or suffer harm to our reputation, our current business, future prospects, financial condition or operating results could be materially harmed. Unfavorable U.S. government audits or results of other investigations could subject us to penalties or sanctions, adversely affect our profitability, harm our reputation and relationships with our customers or impair our ability to win new contracts. The Defense Contract Audit Agency (DCAA) and other government agencies routinely audit and investigate government contracts and contractor systems. These agencies review a contractor's performance on its contract, cost structure and compliance with applicable laws, regulations and standards. The DCAA also reviews the adequacy of, and a contractor's compliance with, its internal control systems and policies, including the contractor's accounting, purchasing, estimating, compensation and management information systems. Allegations of impropriety or deficient controls could harm our reputation or influence the award of new contracts. Any costs found to be improperly allocated to a specific contract will not be reimbursed, while such costs already reimbursed must be refunded. In recent years, U.S. government contractors have faced increased scrutiny by the DCAA and other U.S. government agencies. For example, among other matters, the DCAA has begun to focus on the strict adherence by technology support contractors to labor qualification requirements contained in the terms of U.S. government contracts that we support. If any of our internal control systems or policies is found non-compliant or inadequate, payments may be withheld or suspended under our contracts or we may be subjected to increased government scrutiny and approval requirements that could delay or adversely affect our ability to invoice and receive timely payment on our contracts, perform contracts or compete for contracts with the U.S. government. As a result, a DCAA audit could materially affect our competitive position and result in a substantial adjustment to our revenues and adversely affect our profitability. 19 Our failure to maintain strong relationships with other contractors, or the failure of contractors with whom we have entered into a subcontract or prime contract relationship to meet their contractual obligations to us or our clients, could have a material adverse effect on our business and results of operations. As a prime contractor, we often rely on other companies to perform some of the work under a contract, and we expect to continue to depend on relationships with other contractors for portions of our delivery of services and revenue in the foreseeable future. There is a risk that we may have disputes with our subcontractors arising from, among other things, the quality and timeliness of work performed by the subcontractor, client concerns about the subcontractor, our failure to extend existing task orders or issue new task orders under a subcontract, or our hiring of a subcontractor’s personnel. In addition, if any of our subcontractors fail to deliver the agreed-upon supplies or perform the agreed-upon services on a timely basis, our ability to fulfill our obligations as a prime contractor may be jeopardized. Material losses could arise in future periods and subcontractor performance deficiencies could result in a client terminating a contract for default. A termination for default could expose us to liability and have an adverse effect on our ability to compete for future contracts and orders. For the years ended December 31, 2014 and 2013, we derived 11% and 9% of our revenues, respectively, from contracts in which we acted as a subcontractor to other contractors. As a subcontractor, we often lack control over fulfillment of a contract. Poor performance on such contracts could impact our reputation, even if we perform as required. In addition, as a subcontractor, we may be unable to collect payments owed to us by the prime contractor, even if we have performed our obligations under the contract, as a result of, among other things, the prime contractor’s inability to fulfill the contract. Additionally, we occasionally enter into joint ventures so that we can jointly bid and perform on a particular project. The success of these and other joint ventures depends, in large part, on the satisfactory performance of the contractual obligations by our joint venture partners. If our partners do not meet their obligations, the joint ventures may be unable to adequately perform and deliver their contracted services. Under these circumstances, we may be required to make additional investments and provide additional services to ensure the adequate performance and delivery of the contracted services. These additional obligations could result in reduced profits or, in some cases, significant losses for us with respect to the joint venture, which could also affect our reputation in the industries we serve. Internal system or service failures, including those resulting from cyber or other security threats, could disrupt our business and impair our ability to effectively provide our services to our customers, which could damage our reputation and have a material adverse effect on our business and results of operations. We create, implement and maintain information technology and engineering systems, and provide services that are often critical to our customers' operations, some of which involve classified or other sensitive information in intelligence, national security and other classified or sensitive customer functions. As a result, we are subject to systems or service failures, not only resulting from our own failures or the failures of third-party service providers, natural disasters, power shortages or terrorist attacks, but also from continuous exposure to cyber and other security threats, including computer viruses, attacks by computer hackers or physical break-ins. In particular, as a U.S. government contractor, we face a heightened risk of a security breach or disruption with respect to classified or other sensitive information resulting from disclosure of classified operations, an attack by computer hackers, foreign governments or cyber terrorists. Many government contractors have been the target of these types of attacks in the past and future attacks are likely to occur. If successful, these types of attacks on our network or other systems or service failures could have a material adverse effect on our business and results of operations, due to, among other things, the loss of customer or proprietary data, interruptions or delays in our customers' businesses and damage to our reputation. In addition, the failure or disruption of our systems, communications or utilities could cause us to interrupt or suspend our operations, which could have a material adverse effect on our business and results of operations. 20 If our systems, services or other applications have significant defects or errors, are successfully attacked by cyber and other security threats, suffer delivery delays or otherwise fail to meet our customers' expectations, we may: • • • • • • • • lose revenue due to adverse customer reaction; be required to provide additional services to a customer at no charge; incur additional costs related to monitoring and increasing our cyber security; lose revenue due to the deployment of internal staff for remediation efforts instead of customer assignments; receive negative publicity, which could damage our reputation and adversely affect our ability to attract or retain customers; be unable to successfully market services that are reliant on the creation and maintenance of secure information technology systems to U.S. government, international and commercial customers; suffer claims for substantial damages, particularly as a result of any successful network or systems breach and exfiltration of customer information; or incur significant costs complying with applicable federal or state law, including laws governing protection of personal information. In addition to any costs resulting from contract performance or required corrective action, these failures may result in increased costs or loss of revenues if they result in customers postponing subsequently scheduled work or canceling or failing to renew contracts. Our errors and omissions insurance coverage may not continue to be available on reasonable terms or in sufficient amounts to cover one or more large claims or the insurer may disclaim coverage as to some types of future claims. The successful assertion of any large claim against us could seriously harm our business. Even if not successful, these claims could result in significant legal and other costs, may be a distraction to our management and may harm our customer relationships. Security breaches in customer systems could adversely affect our business. Many of the programs we support and systems we develop, install and maintain involve managing and protecting information involved in intelligence, national security and other classified or sensitive customer functions. While we have programs designed to comply with relevant security laws, regulations and restrictions, a security breach in one of these systems could cause serious harm to our business, damage our reputation and prevent us from being eligible for further work on critical systems for our current customers or for other U.S. government customers generally. Losses that we could incur from such a security breach could exceed the policy limits that we have for errors and omissions and product liability insurance coverage. Damage to our reputation or limitations on our eligibility for additional work resulting from a security breach in one of the systems we develop, install and maintain could materially reduce our revenues. If we fail to recruit and retain skilled employees or employees with the necessary skill sets or security clearances, we might not be able to perform under our contracts or win new business and our growth may be limited. To be competitive, we must have employees who have advanced information technology and technical services skills and who work well with our customers in a government or defense-related environment. Often, these employees must have some of the highest security clearances in the United States. These employees are in great demand and are likely to remain a limited resource in the foreseeable future. Recruiting, training and retention costs can place significant demands on our resources. If we are unable to recruit and retain a sufficient number of these employees, our ability to maintain and grow our business could be negatively impacted. If we are required to engage larger numbers of contracted personnel, our profit margins could be adversely affected. In addition, some of our contracts contain provisions requiring us to commit to staff a program with certain personnel the customer considers key to our successful performance under the contract. In the event we are unable to provide these key personnel or acceptable substitutions, the customer may terminate the contract and we may not be able to recover certain incurred costs. 21 Our business depends upon obtaining and maintaining required security clearances. Many of our U.S. government contracts require our employees to maintain various levels of security clearances and we are required to maintain certain facility security clearances complying with the Department of Defense and intelligence community requirements. Obtaining and maintaining security clearances for employees involves a lengthy process and it is difficult to identify, recruit and retain employees who already hold security clearances. If our employees are unable to obtain or retain security clearances or if our employees who hold security clearances terminate employment with us, the customer whose work requires cleared employees could terminate the contract or decide not to renew it upon its expiration. In addition, we expect that many of the contracts on which we will bid will require us to demonstrate our ability to obtain facility security clearances and perform work with employees who hold specified types of security clearances. To the extent we are not able to obtain facility security clearances or engage employees with the required security clearances for a particular contract, we may not be able to bid on or win new contracts, or effectively re-bid on expiring contracts. Covenants in the instruments governing our revolving credit facility may restrict our financial and operating flexibility. We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as administrative agent. The credit agreement provides for a $500 million revolving credit facility. The maturity date for the credit agreement is June 13, 2019. The credit agreement requires the Company to comply with specified financial covenants, including the maintenance of certain consolidated total leverage ratios and a certain fixed charge coverage ratio, and contains negative covenants that, among other things, may limit or impose restriction on the ability of the Company to incur additional indebtedness, make investments, make acquisitions and undertake certain other actions. Additionally, any event of default under the Credit Agreement, could have a material adverse effect on our business if the creditors determine to exercise their rights. Our overall profit margins on our contracts may decrease and our results of operations could be adversely affected if materials and subcontract revenues grow at a faster rate than labor-related revenues. Our revenues are generated both from the efforts of our employees (labor-related revenues) and from the receipt of payments for the cost of materials and subcontracts we use in connection with performing our services (materials and subcontract revenues). Generally, our materials and subcontract revenues have lower profit margins than our labor-related revenues. If our materials and subcontract revenues grow at a faster rate than labor-related revenues, our overall profit margins may decrease and our profitability could be adversely affected. Our business operations involve considerable risks and hazards. An accident or incident involving our employees or third parties could harm our reputation, affect our ability to compete for business, and if not adequately insured or indemnified, could adversely affect our results of operations and financial condition. Our business involves providing services that require some of our employees to operate in countries that may be experiencing political unrest, war or terrorism. As a result, during the course of such deployments we are exposed to liabilities arising from accidents or incidents involving our employees or third parties. Any of these types of accidents or incidents could involve significant potential injury or other claims by employees and/or third parties. It is also possible that we will encounter unexpected costs in connection with additional risks inherent in sending our employees to dangerous locations, such as increased insurance costs, as well as the repatriation of our employees or executives for reasons beyond our control. We maintain insurance policies that mitigate risk and potential liabilities related to our operations. Our insurance coverage may not be adequate to cover those claims or liabilities, and we may be forced to bear substantial costs from an accident or incident. Substantial claims in excess of our related insurance coverage could adversely affect our operating performance and may result in additional expenses and possible loss of revenues. Furthermore, any accident or incident for which we are liable, even if fully insured, may result in negative publicity that could adversely affect our reputation among our customers and the public, which could result in us losing existing and future contracts or make it more difficult to compete effectively for future contracts. This could adversely affect our operating performance and may result in additional expenses and possible loss of revenues. 22 Our employees or subcontractors may engage in misconduct or other improper activities, which could cause us to lose customers or affect our ability to contract with the U.S. government. Because we are a government contractor, should an employee or subcontractor commit fraud or should other misconduct occur, such occurrences could have an adverse impact on our business and reputation. Misconduct by employees, subcontractors or joint venture partners could involve intentional failures to comply with federal laws including: U.S. government procurement regulations; requirements for handling of sensitive or classified information; the terms of our contracts; or proper time-keeping practices. These actions could lead to civil, criminal and/or administrative penalties (including fines, imprisonment, suspension and/or debarment from performing U.S. government contracts) and harm our reputation. The precautions we take to prevent and detect such activity may not be effective in controlling unknown or unmanaged risks or losses. We face risks associated with our international business. Our business operations are subject to a variety of risks associated with conducting business internationally, including: • Changes in or interpretations of foreign laws or policies that may adversely affect the performance of our services; • • Political instability in foreign countries; Imposition of inconsistent laws or regulations; • Conducting business in places where laws, business practices and customs are unfamiliar or unknown; • Imposition of limitations on or increase of withholding and other taxes on payments by foreign subsidiaries or joint ventures; and • Compliance with a variety of U.S. laws, including the Foreign Corrupt Practices Act and U.S. export control regulations, by us or subcontractors. Although such risks have not significantly impacted our business to date, we do not know the impact that these regulatory, geopolitical and other factors could have on our business in the future. 23 Risks Related to Our Stock Our quarterly operating results may fluctuate. Our quarterly revenues and operating results may fluctuate as a result of a number of factors, many of which are outside of our control. For these reasons, comparing our operating results on a period-to-period basis may be of limited significance in some cases, and as such, you should not rely on our past results as an indication of our future performance. While our financial results may be negatively affected by any of the risk factors identified in this section of our Form 10-K, a number of factors could cause our revenues, cash flows and operating results to vary from quarter-to-quarter, including: • Timing of award or performance incentive fee notices; • Fluctuations in revenues earned on fixed-price contracts and contracts with a performance-based fee structure; • Commencement, completion or termination of contracts during any particular quarter; • Reallocation of funds to customers due to priority; • Timing of significant bid and proposal costs; • Variable purchasing patterns under government contracts, blanket purchase agreements and ID/IQ contracts; • • Seasonal or quarterly fluctuations in our workdays and staff utilization rates; Strategic decisions by us or our competitors, such as acquisitions, divestitures, spin-offs and joint ventures; • Changes in Presidential administrations and senior U.S. government officials that affect the timing of technology procurement; • Changes in U.S. government policy or budgetary measures that adversely affect government contracts in general; and • Changes in the volume of purchase requests from customers for equipment and materials. Because a relatively large amount of our expenses are fixed, cash flows from our operations may vary significantly as a result of changes in the volume of services provided under existing contracts and the number of contracts that are commenced, completed or terminated during any quarter. We incur significant operating expenses during the start-up and early stages of large contracts and typically we do not receive corresponding payments in that same quarter. We may also incur significant or unanticipated expenses when a contract expires, terminates or is not renewed. We may change our dividend policy in the future. The Company has maintained a regular cash dividend program since 2011. We anticipate paying quarterly dividends for 2015 pursuant to such program. However, any future payment of dividends, including the timing and amount of any such dividends, will be at the discretion of our Board of Directors and will depend upon our earnings, liquidity, financial condition and such other factors as our Board of Directors considers relevant. A change in our dividend policy could have an adverse effect on the market price of our common stock. Mr. Pedersen, our Chairman and Chief Executive Officer, effectively controls our Company, and his interests may not be aligned with those of other stockholders. As of December 31, 2014, Mr. Pedersen owned approximately 35% of our total outstanding shares of common stock. Holders of our Class B common stock are entitled to ten votes per share, while holders of our Class A common stock are entitled to only one vote per share. Mr. Pedersen beneficially owned 13,192,845 shares of Class B common stock as of December 31, 2014, thus he controlled approximately 85% of the combined voting power of our stock as of December 31, 2014. Accordingly, Mr. Pedersen controls the vote on all matters submitted to a vote of our stockholders. As long as Mr. Pedersen beneficially owns a majority of the combined voting power of our common stock, he will have the ability, without the consent of our public stockholders, to elect all members of our Board of Directors and to control our management and affairs. 24 Mr. Pedersen's voting control may have the effect of preventing or discouraging transactions involving an actual or a potential change of control of the Company, regardless of whether a premium is offered over then-current market prices. Mr. Pedersen will be able to cause a change of control of the Company. Mr. Pedersen's voting control could adversely affect the trading price of our common stock if investors perceive disadvantages in owning stock in a company with such concentrated ownership. Mr. Pedersen could also cause a registration statement to be filed and to become effective under the Securities Act of 1933, thereby permitting him to freely sell or transfer the shares of common stock that he owns, which could have an impact on the trading price of our stock. Provisions in our charter documents and Delaware law may inhibit potential acquisition bids that you and other stockholders may consider favorable, and the market price of our Class A common stock may be lower as a result. There are provisions in our certificate of incorporation and bylaws that make it more difficult for a third party to acquire, or attempt to acquire, control of our Company, even if a change of control were considered favorable by you and other stockholders. Among the provisions that could have an anti-takeover effect, are provisions relating to the following: • The high vote nature of our Class B common stock; • The ability of the Board of Directors to issue preferred stock; • The inability of stockholders to take action by written consent; and • The advance notice requirements for director nominations or other proposals submitted by our stockholders. Item 1B. Unresolved SEC Staff Comments We have not received any written comments from the SEC staff regarding our periodic or current reports under the Exchange Act that remain unresolved. Item 2. Properties We lease our facilities, including offices, warehouses and labs, and we do not own any facilities or real estate materially important to our operations. Our facilities are leased in close proximity to our customers. As of December 31, 2014, we leased 36 facilities throughout the metropolitan Washington, D.C. area and 29 facilities in other parts of the United States, for approximately 1.4 million square feet. We also have employees working at customer sites throughout the United States and in other countries. Our leases expire between 2015 and 2022. We believe our current facilities are adequate to meet our current needs. We do not anticipate any significant difficulty in renewing our leases or finding alternative space to lease upon the expiration of our leases and to support our future growth. Item 3. Legal Proceedings We are subject to certain legal proceedings, government audits, investigations, claims and disputes that arise in the ordinary course of our business. Like most large government defense contractors, our contract costs are audited and reviewed on a continual basis by an in-house staff of auditors from the DCAA. In addition to these routine audits, we are subject from time-to-time to audits and investigations by other agencies of the U.S. government. These audits and investigations are conducted to determine if our performance and administration of our government contracts are compliant with contractual requirements and applicable federal statutes and regulations. An audit or investigation may result in a finding that our performance, systems and administration is compliant or, alternatively, may result in the government initiating proceedings against us or our employees, including administrative proceedings seeking repayment of monies, suspension and/or debarment from doing business with the U.S. government or a particular agency or civil or criminal proceedings seeking penalties and/or fines. Audits and investigations conducted by the U.S. government frequently span several years. Although we cannot predict the outcome of these and other legal proceedings, investigations, claims and disputes, based on the information now available to us, we do not believe the ultimate resolution of these matters, either individually or in the aggregate, will have a material adverse effect on our business, prospects, financial condition or operating results. 25 Item 4. Mine Safety Disclosures Not applicable. 26 PART II Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Market Information Our Class A common stock has been quoted on the Nasdaq Stock Market under the symbol “MANT” since our initial public offering on February 7, 2002. The following table sets forth, for the periods indicated, the high and low prices of our shares of common stock, as reported on the Nasdaq Stock Market. 2014 First Quarter Second Quarter Third Quarter Fourth Quarter 2013 First Quarter Second Quarter Third Quarter Fourth Quarter High $31.10 $31.32 $30.10 $31.06 High $27.54 $28.25 $30.21 $30.45 Low $27.43 $27.78 $26.36 $26.09 Low $23.20 $23.89 $25.53 $27.06 There is no established public market for our Class B common stock. As of February 18, 2015, there were 60 holders of record of our Class A common stock and 3 holders of record of our Class B common stock. The number of holders of record of our Class A common stock is not representative of the number of beneficial holders because many of the shares are held by depositories, brokers or nominees. Dividend Policy During fiscal years 2014 and 2013, we declared and paid quarterly dividends, each in the amount of $0.21 per share, on all issued and outstanding shares of common stock. For 2015, we anticipate we will continue paying quarterly dividends, however any future dividends declared will be at the discretion of our Board of Directors and will depend, among other factors, upon our results of operations, financial condition and cash requirements, as well as such other factors our Board of Directors deems relevant. Recent Sales of Unregistered Securities We did not issue or sell any securities in fiscal year 2014 that were not registered under the Securities Act of 1933. Equity Compensation Plan Information Information regarding our equity compensation plans and the securities authorized for issuance thereunder is incorporated by reference in Item 12 “Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.” Purchase of Equity Securities The Company did not purchase equity securities during the year ended December 31, 2014. 27 Performance Graph The stock performance graph compares the cumulative total shareholder return of ManTech common stock to the Nasdaq Stock Market (U.S.) Index, Standard & Poor's MidCap 400 Index, Russell 2000 Index and North American Tech Services Index. The period measured is December 31, 2009 to December 31, 2014. The graph assumes an investment of $100 in ManTech common stock and each of the indices with reinvestment of all dividends. 28 Item 6.

For additional information on the non-cash goodwill impairment charge, see Note 7 to our consolidated financial statements in Item 8. (3) Over the past five years, we completed 10 acquisitions. In aggregate, these acquisitions have added $482.5 million in goodwill. For additional information on our recent acquisitions, see Note 3 to our consolidated financial statements in Item 8. Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations The following discussion of our financial condition and results of operations should be read together with the consolidated financial statements and the notes to those statements included in Item 8 “Financial Statements and Supplemental Data.” This discussion contains forward-looking statements that involve risks and uncertainties. For a description of these forward-looking statements, refer to Part I “Forward-Looking Statements.” A description of factors that could cause actual results to differ materially from the results we anticipate include, but are not limited to, those discussed in Item 1A “Risk Factors,” as well as discussed elsewhere in this Annual Report. Overview ManTech is a leading provider of innovative technologies and solutions for mission-critical national security programs for the intelligence community; the departments of Defense, State, Homeland Security, Health and Human Services, Veteran Affairs and Justice, including the Federal Bureau of Investigation (FBI); the space communities; and other U.S. government customers. We derive revenues primarily from contracts with U.S. government agencies that are focused on national security and consequently our operational results are affected by U.S. government spending levels in the areas of defense, intelligence and homeland security. Over the past two years, financial performance in our industry has been adversely impacted by public and political pressure regarding government funding levels, uncertainty about the appropriations process and delays in contract awards and spending. In addition, as U.S. forces have withdrawn from Afghanistan, revenues from our contracts in support of Overseas 29 Contingency Operations (OCO) have substantially declined. The delays in contract awards in 2013 and 2014 have had continued impacts on our performance. While we expect an overall reduction in OCO work in 2015 as compared to 2014, we do expect the levels of work that exist as we are exiting 2014 to remain relatively stable through 2015. Despite uncertainties over the past two years, we believe we are well positioned to meet our customers' needs and grow our business as we move beyond 2014. Revenues Substantially all of our revenues are derived from services and solutions provided to the U.S. government or to prime contractors supporting the U.S. government, including services provided by our employees, our subcontractors and through solutions that include third-party hardware and software that we purchase and integrate as a part of our overall solutions. These requirements may vary from period-to-period depending on specific contract and customer requirements. The following table shows revenues from each type of customer as a percentage of total revenues for the periods presented. Department of Defense and intelligence agencies Federal civilian agencies State agencies, international agencies and commercial entities Total Year Ended December 31, 2013 95.6% 3.4% 1.0% 100.0% 2014 92.2% 6.7% 1.1% 100.0% 2012 95.4% 3.8% 0.8% 100.0% Our prime contractor revenues as a percentage of our total revenues are 89%, 91% and 90% for the years ended December 31, 2014, 2013 and 2012, respectively. We provide our services and solutions under three types of contracts: cost-reimbursable; time-and-materials; and fixed-price. Cost-reimbursable contracts-Under cost-reimbursable contracts, we are reimbursed for costs that are determined to be reasonable, allowable and allocable to the contract and paid a fee representing the profit margin negotiated between us and the contracting agency, which may be fixed or performance based. Under cost-reimbursable contracts we recognize revenues and an estimate of applicable fees earned as costs are incurred. We consider fixed fees under cost-reimbursable contracts to be earned in proportion to the allowable costs incurred in performance of the contract. For performance based fees under cost-reimbursable contracts, we recognize the relevant portion of the expected fee to be awarded by the customer at the time such fee can be reasonably estimated, based on factors such as our prior award experience and communications with the customer regarding performance, or upon customer approval. Fixed-price contracts-Under fixed-price contracts, we perform specific tasks for a fixed price. Fixed-price contracts may include either a product delivery or specific service performance over a defined period. Revenues on fixed-price contracts that provide for the Company to render services throughout a period are recognized as earned according to contract terms as the service is provided on a proportionate performance basis. For fixed-price contracts that provide for the delivery of a specific product with related customer acceptance provisions, revenues are recognized as those products are delivered and accepted. Time-and-materials contracts-Under time-and-materials contracts, we are reimbursed for labor at fixed hourly rates and generally reimbursed separately for allowable materials, costs and expenses at cost. We recognize revenues under time-and- materials contracts by multiplying the number of direct labor hours expended by the contract billing rates and adding the effect of other billable direct costs. 30 Our contract mix varies from year-to-year due to numerous factors, including our business strategies and U.S. government procurement objectives. The following table shows revenues from each of these types of contracts as a percentage of total revenues for the periods presented. Cost-reimbursable Fixed-price Time-and-materials Total Year Ended December 31, 2014 2013 2012 68.9% 21.1% 10.0% 100.0% 72.3% 16.8% 10.9% 100.0% 51.0% 16.2% 32.8% 100.0% Under cost-reimbursable contracts, there is limited financial risk, because we are reimbursed for all allowable direct and indirect costs. However, profit margins on this type of contract tend to be lower than on time-and-materials and fixed-price contracts, and as a result of the shift in our contract mix, our profits have been impacted. Cost of Services Cost of services primarily includes direct costs incurred to provide our services and solutions to customers. The most significant portion of these costs are direct labor costs, including salaries and wages, plus associated fringe benefits of our employees directly serving customers, in addition to the related management, facilities and infrastructure costs. Cost of services also includes other direct costs, such as the costs of subcontractors and outside consultants and third-party materials, including hardware or software that we purchase and provide to the customer as part of an integrated solution. Changes in the mix of services and equipment provided under our contracts can result in variability in our contract margins. Since we earn higher profits on our own labor services, we expect the ratio of cost of services as a percent of revenues to decline when our labor services mix increases relative to subcontracted labor or third-party materials. Conversely, as subcontracted labor or third-party material purchases for customers increase relative to our own labor services, we expect the ratio of cost of services as a percent of revenues to increase. The proportion that costs of services bears to revenues varies in part based on our mix of revenues by contract type. In general, cost-reimbursable contracts are the least profitable of our government contracts but offer the lowest risk of loss. Under time-and- materials contracts, to the extent that our actual labor costs are higher or lower than the billing rates under the contract, our profit under the contract may either be greater or less than we anticipated or we may suffer a loss under the contract. In general, we realize a higher profit margin on work performed under time-and-materials contracts than cost-reimbursable contracts. Fixed- price contracts generally offer higher profit margin opportunities but involve great financial risk because we bear the impact of cost overruns in return for the full benefit of any cost savings. General and Administrative Expenses General and administrative expenses include the salaries and wages, plus associated fringe benefits of our employees not performing work directly for customers, and associated facilities costs. Among the functions covered by these costs are corporate business development, bid and proposal, contracts administration, finance and accounting, legal, corporate governance and executive and senior management. In addition, we included stock-based compensation, as well as depreciation and amortization expenses related to the general and administrative function. Depreciation and amortization expenses include the depreciation of computers, furniture and other equipment, the amortization of third party software we use internally, leasehold improvements and intangible assets. Intangible assets include customer relationships and contract backlogs acquired in business combinations, and are amortized over their estimated useful lives. We classify indirect costs incurred as cost of services and general and administrative expenses in the same manner as such costs are defined in our disclosure statements under U.S. Government Cost Accounting Standards. Effective January 1, 2014, we updated our disclosure statements with the Defense Contract Management Agency, resulting in certain costs being classified differently either as cost of services or as general and administrative expenses on a prospective basis. This change has caused a net increase in the reported cost of services and a net decrease in reported general and administrative expenses in 2014 as compared to 2013 and 2012; however, total operating costs were not affected by this change. 31 Interest Expense Interest expense is primarily related to interest expense incurred or accrued under our outstanding borrowings on our debt and deferred financing charges. Interest Income Interest income is primarily from cash on hand and late invoice payments by the government. Results of Operations Year Ended December 31, 2014 Compared to Year Ended December 31, 2013 Consolidated Statements of Income and Loss The following table sets forth certain items from our consolidated statements of income and loss and the relative percentages that certain items of expense and earnings bear to revenues as well as the year-over-year change from December 31, 2013 to December 31, 2014. Year Ended December 31, 2014 2013 2014 2013 Dollars Percentages (dollars in thousands) Year-to-Year Change 2013 to 2014 Dollars Percent REVENUES Cost of services $ 1,773,981 $ 2,310,072 1,524,208 1,995,630 100.0% 85.9% 100.0% $ 86.4% (536,091) (471,422) (23.2)% (23.6)% General and administrative expenses Goodwill impairment OPERATING INCOME Loss on extinguishment of debt Interest expense Interest income Other income (expense), net INCOME FROM OPERATIONS BEFORE INCOME TAXES AND EQUITY METHOD INVESTMENTS Provision for income taxes Equity in losses of unconsolidated subsidiaries NET INCOME (LOSS) Revenues 154,957 — 94,816 (10,074) (5,802) 394 (233) 79,101 (31,525) (282) $ 47,294 $ 173,772 118,427 22,243 — (16,266) 608 (32) 6,553 (11,842) (860) (6,149) 8.8% —% 5.3% 0.6% 0.2% —% —% 4.5% 1.8% —% 2.7% (18,815) (118,427) 72,573 (10,074) 10,464 (214) (201) (10.8)% (100.0)% 326.3 % (100.0)% 64.3 % (35.2)% (628.1)% 72,548 (19,683) 1,107.1 % 166.2 % 7.5% 5.1% 1.0% —% 0.7% —% —% 0.3% 0.5% —% 0.2% $ 53,443 578 (67.2)% 869.1 % The primary driver of our decrease in revenues relates to reduced demand for services supporting Overseas Contingency Operations (OCO) as a result of the withdrawal of U.S. forces and reduction in military operations in Afghanistan. The reduction in our OCO related work in 2014 as compared to the same period in 2013 was primarily due to reduced demand on a sustainment contract for Mine-Resistant Ambush-Protected (MRAP) vehicles and reduced demand for field service support on C4ISR systems. In addition, we had a surge in equipment deliveries in the first quarter of 2013 on a contract for IT infrastructure modernization in the intelligence area as well as programs that ended. These reductions were partially offset by revenues from our recent acquisitions. While we expect an overall reduction in OCO work in 2015 as compared to 2014, we do expect the levels of work that exist as we are exiting 2014 to remain relatively stable through 2015. 32 Cost of services The decrease in cost of services was primarily due to reductions in revenues. As a percentage of revenues, direct labor costs increased to 43.4% for the year ended December 31, 2014, as compared to 37.9% for the same period in 2013. As a percentage of revenues, other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, was 42.5% for the year ended December 31, 2014, compared to 48.5% for the same period in 2013. We expect cost of services as a percentage of revenues to remain relatively stable in 2015. General and administrative expenses The decrease in general and administrative expense was due to cost reduction measures as well as certain costs being classified as cost of services instead of general and administrative expenses in 2014. We classify indirect costs in a manner consistent with disclosure statements filed with and approved by the Defense Contract Management Agency. Effective January 1, 2014, updates to our disclosure statements resulted in changes to the presentation of certain costs. Changes such as these do not impact the overall expense incurred or operating income and are presented prospectively. The reclassification of expenses and cost reductions were partially offset by increased bid and proposal spending in pursuit of larger contract opportunities and research and development expenditures to enhance technologies around our offerings. As a percentage of revenues, general and administrative expenses increased for the year ended December 31, 2014 when compared to the same period in 2013. We expect general and administrative expenses as a percentage of revenues to remain relatively stable or decrease slightly in 2015. Goodwill impairment During the fourth quarter of 2013, multiple events and circumstances indicated a significant reduction in the operating performance outlook of one of our reporting units. These events included being awarded fewer contracts than anticipated on several competitive opportunities, changing mission priorities of the U.S. government in relation to certain of our C4ISR contracts and OCO-related work (primarily on maintenance and sustainment of MRAP vehicles), continued delays in our customers' procurement cycle due, in part, to the U.S. government shutdown, and continued margin pressure on some of our contracts. The culmination of these events led us to conduct an interim impairment analysis on the impacted reporting unit. As a result of this analysis, we recorded a non-cash impairment charge of $118.4 million for the period ending December 31, 2013. For additional information, see Note 7 to our consolidated financial statements in Item 8. Loss on extinguishment of debt On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes. The 7.25% senior unsecured notes were redeemed at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. As a result of the redemption of our 7.25% senior unsecured notes, we recorded a loss on the extinguishment of debt for $10.1 million for the year ended December 31, 2014. Interest expense The decrease in interest expense was primarily due to the redemption of the 7.25% senior unsecured notes on April 15, 2014. We expect minimal interest expense in 2015 due to the redemption of 7.25% senior unsecured notes in 2014. Provision for income taxes Our effective tax rate is affected by recurring items, such as tax rates and the relative amount of income we earn in various taxing jurisdictions. It is also affected by discrete items that may occur in any given year, but are not consistent from year-to-year. Our effective income tax rates were 40.0% and 208.0% for the years ended December 31, 2014 and 2013, respectively. The decrease in the effective tax rate is due to the non-deductible portion of the non-cash goodwill impairment charge in 2013. Absent the effects of the goodwill impairment charge in 2013, our effective tax rate has increased. This increase is largely driven by a reduction of work performed outside the U.S. which is increasing the proportion of our income apportioned to state jurisdictions. In addition, 2013 contained a one time tax basis deduction on an investment. In 2015, we expect our effective tax rate to remain relatively consistent. 33 Equity in losses of unconsolidated subsidiaries Equity in losses of unconsolidated subsidiaries represents earnings or losses from joint ventures that we account for under the equity method. The losses are primarily due to bid and proposal expenditures of our Fluor-ManTech Logistics Solutions, LLC joint venture. For additional information, see Note 14 to our consolidated financial statements in Item 8. Year Ended December 31, 2013 Compared to Year Ended December 31, 2012 Consolidated Statements of Income and Loss The following table sets forth certain items from our consolidated statements of income and the relative percentages that certain items of expense and earnings bear to revenues as well as the year-over-year change from December 31, 2012 to December 31, 2013. Year Ended December 31, 2012 2013 2012 2013 Dollars Percentages (dollars in thousands) REVENUES Cost of services $ 2,310,072 $ 2,582,295 1,995,630 2,213,894 100.0% 86.4% 100.0% $ 85.7% General and administrative expenses Goodwill impairment OPERATING INCOME Interest expense Interest income Other income (expense), net INCOME FROM OPERATIONS BEFORE INCOME TAXES AND EQUITY METHOD INVESTMENTS Provision for income taxes Equity in losses of unconsolidated subsidiaries NET INCOME (LOSS) Revenues 173,772 118,427 22,243 (16,266) 608 (32) 197,413 — 170,988 (16,304) 344 (74) 6,553 (11,842) 154,954 (59,935) (860) — $ (6,149) $ 95,019 7.5% 5.1% 1.0% 0.7% —% —% 0.3% 0.5% —% 0.2% Year-to-Year Change 2012 to 2013 Dollars Percent (272,223) (218,264) (23,641) 118,427 (148,745) 38 264 42 (10.5)% (9.9)% (12.0)% 100.0 % (87.0)% (0.2)% 76.7 % (56.8)% 7.7% —% 6.6% 0.6% —% —% 6.0% 2.3% (148,401) 48,093 (95.8)% (80.2)% —% 3.7% $ (860) (101,168) (100.0)% (106.5)% The primary driver of our decrease in revenues relates to reduced demand for services supporting Overseas Contingency Operations (OCO) as a result of the accelerated withdrawal of U.S. forces and reduction in military operations in Afghanistan. The reduction in our OCO related work in 2013 was primarily due to reduced demand on a sustainment contract for Mine-Resistant Ambush-Protected (MRAP) vehicles and reduced demand for field service support on C4ISR systems. These reductions were partially offset by revenue provided from contracts in the intelligence area, including contracts for IT infrastructure modernization and from growth and healthcare IT programs. Cost of services The decrease in cost of services was primarily due to reductions in revenues. As a percentage of revenues, direct labor costs increased to 37.9% for the year ended December 31, 2013, as compared to 36.1% for the same period in 2012. As a percentage of revenues, other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, was 48.5% for the year ended December 31, 2013, compared to 49.6% for the same period in 2012. 34 General and administrative expenses The decrease in general and administrative expenses was due to cost reduction initiatives, including reductions in indirect support staff and lower stock based compensation expense. As a percentage of revenues, general and administrative expenses were slightly lower for the year ended December 31, 2013 when compared to the same period in 2012. Goodwill impairment Due to a significant reduction in the performance outlook of one of our reporting units during 2013, we recorded a non-cash goodwill impairment charge of $118.4 million during 2013. For additional information, see Note 7 to our consolidated financial statements in Item 8. Provision for income taxes Our effective tax rate is affected by recurring items, such as tax rates and the relative amount of income we earn in various taxing jurisdictions. It is also affected by discrete items that may occur in any given year, but are not consistent from year-to-year. Our effective income tax rates were 208.0% and 38.7% for the years ended December 31, 2013 and 2012, respectively. The increase in the effective tax rate is due to the non-deductible portion of the 2013 non-cash goodwill impairment charge. Equity in losses of unconsolidated subsidiaries We account for our investment in the Fluor-ManTech Logistics Solutions, LLC under the equity method of accounting, which resulted in $(0.9) million and $0 in equity method losses for the years ended December 31, 2013 and 2012, respectively. Net income (loss) The decrease in net income (loss) was due to a non-cash goodwill impairment charge, a reduction in revenues and margin pressure due to a shift to cost-reimbursable contract awards as well as the competitive market place. Backlog For the years ended December 31, 2014, 2013 and 2012 our backlog was $3.3 billion, $3.9 billion and $6.5 billion, respectively, of which $0.8 billion, $1.1 billion and $1.8 billion, respectively, was funded backlog. The decrease in our backlog is primarily due to reduced demand on OCO contracts resulting from the accelerated withdrawal from Afghanistan. Backlog represents estimates that we calculate on a consistent basis. For additional information on how we compute backlog, see “Backlog” in Item 1 “Business.” Liquidity and Capital Resources Historically, our primary liquidity needs have been the financing of acquisitions, working capital, payment under our cash dividend program and capital expenditures. Our primary sources of liquidity are cash provided by operations and our revolving credit facility. On December 31, 2014, our cash and cash equivalents balance was $23.8 million. There were no outstanding borrowings under our revolving credit facility at December 31, 2014. At December 31, 2014, we were contingently liable under letters of credit totaling $0.8 million, which reduces our ability to borrow under our revolving credit facility by that amount. The maximum available borrowings under our revolving credit facility at December 31, 2014 were $499.2 million. On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes. The 7.25% senior unsecured notes were redeemed at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. Generally, cash provided by operating activities is adequate to fund our operations, including payments under our regular cash dividend program. Due to fluctuations in our cash flows and level of operations, it may become necessary from time-to-time to increase borrowings under our revolving credit facility to meet cash demands. 35 Cash Flows from Operating Activities Our operating cash flow is primarily affected by our ability to invoice and collect from our clients in a timely manner, our ability to manage our vendor payments and the overall profitability of our contracts. We bill most of our customers monthly after services are rendered. Our accounts receivable days sales outstanding (DSO) were 83 and 84 for the years ended December 31, 2014 and 2013, respectively. For the years ended December 31, 2014, 2013 and 2012, our net cash flows from operating activities were $126.9 million, $188.3 million and $126.3 million, respectively. The decrease in net cash flows from operating activities during the year ended December 31, 2014 when compared to the same period in 2013 was primarily due to lower amounts of income, excluding the effects of the 2013 non-cash goodwill impairment charge, and a lower volume of sales in 2014. The increase in net cash flows from operating activities during the year ended December 31, 2013 compared to the same period in 2012 was primarily due to the collection of accounts receivable and the timing of payments to our vendors and employees. Cash Flows from Investing Activities Our cash flow from investing activities consists primarily of business combinations, purchases of property and equipment and investments in capitalized software for internal use. For the years ended December 31, 2014, 2013 and 2012 our net cash outflows from investing activities were $135.9 million, $24.8 million and $76.0 million, respectively. For the year ended December 31, 2014, our net cash outflows from investing activities were primarily due to the acquisitions of 7Delta Inc. and Allied Technology Group, Inc. and capital expenditures. For the year ended December 31, 2013, our net cash outflows from investing activities were due to the acquisition of ALTA Systems, Inc. and capital expenditures. For the year ended December 31, 2012, our net cash outflows from investing activities were due to the acquisition of HBGary, Inc. and Evolvent Technologies, Inc. and capital expenditures. Cash Flows from Financing Activities For the years ended December 31, 2014, 2013 and 2012, our net cash outflows from financing activities were $236.3 million, $29.4 million and $29.8 million, respectively. For the year ended December 31, 2014, our net cash outflows from financing activities were due to the repayment of our senior unsecured notes and dividends paid. For the years ended December 31, 2013 and 2012, our net cash outflows from financing activities resulted primarily from dividends paid. Revolving Credit Facility We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as sole administrative agent. The credit agreement provides for a $500 million revolving credit facility, with a $25 million letter of credit sublimit and a $30 million swing line loan sublimit. The credit agreement also includes an accordion feature that permits the Company to arrange with the lenders for the provision of additional commitments. On June 13, 2014, we amended and restated the credit agreement, and extended the maturity date to June 13, 2019. We deferred $3.4 million in debt issuance costs, cumulatively over the agreements, which are amortized over the term of the amended and restated credit agreement. Borrowings under our credit agreement are collateralized by substantially all the assets of ManTech and its Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by the Company at the time of borrowing: a London Interbank Offer Rate (LIBOR) based rate plus market spreads (1.25% to 2.25% based on our consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on our consolidated total leverage ratio). The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain conditions. The credit agreement requires the Company to comply with specified financial covenants, including the maintenance of certain consolidated leverage ratios and a certain consolidated coverage ratio. The credit agreement also contains various covenants, including affirmative covenants with respect to certain reporting requirements and maintaining certain business activities, and negative covenants that, among other things, may limit or impose restrictions on our ability to incur liens, incur additional indebtedness, make investments, make acquisitions and undertake certain other actions. As of, and during, December 31, 2014 and 2013, we were in compliance with our financial covenants under the credit agreement. There were no outstanding balances on our revolving credit facility at December 31, 2014 and 2013. 36 7.25% Senior Unsecured Notes On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes issued on April 13, 2010 for $200.0 million, which were registered under the Securities Act of 1933. The 7.25% senior unsecured notes were redeemed at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. As a result of the redemption of our 7.25% senior unsecured notes, we recorded a loss on the extinguishment of debt for $10.1 million as non-operating income on our consolidated statement of income during the year ended December 31, 2014. Capital Resources We believe the capital resources available to us from cash on hand of $23.8 million at December 31, 2014, our $500 million capacity under our revolving credit facility and cash from our operations are adequate to fund our anticipated cash requirements for at least the next year, including payments under our regular cash dividend program. We anticipate financing our external growth from acquisitions and our longer-term internal growth through one or more of the following sources: cash from operations; use of our revolving credit facility; and additional borrowings of debt or issuance of equity. Short-Term Borrowings From time-to-time, we borrow funds against our revolving credit facility for working capital requirements and funding of operations, as well as acquisitions. Borrowings bear interest at one of the following variable rates as selected by the Company at the time of borrowing: a London Interbank Offer Rate (LIBOR) based rate plus market spreads (1.25% to 2.25% based on our consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on our consolidated total leverage ratio). In the next year we may use, as needed, our revolving credit facility or additional sources of borrowings in order to fund our anticipated cash requirements. Cash Management To the extent possible, we invest our available cash in short-term, investment grade securities in accordance with our investment policy. Under our investment policy, we manage our investments in accordance with the priorities of maintaining the safety of our principal, maintaining the liquidity of our investments, maximizing the yield on our investments and investing our cash to the fullest extent possible. Our investment policy provides that no investment security can have a final maturity that exceeds six months and that the weighted average maturity of the portfolio cannot exceed 60 days. Cash and cash equivalents include cash on hand, amounts due from banks and short-term investments with maturity dates of three months or less at the date of purchase. Dividend During the years ended December 31, 2014 and 2013, we declared and paid quarterly dividends in the amount of $0.21 per share on both classes of common stock. While we expect to continue the regular cash dividend program, any future dividends declared will be at the discretion of our Board of Directors and will depend, among other factors, upon our results of operations, financial condition and cash requirements, as well as such other factors our Board or Directors deems relevant. Off-Balance Sheet Arrangements In the ordinary course of business, we use letters of credit issued to satisfy certain contractual terms with our customers. As of December 31, 2014, $0.8 million in letters of credit were issued but undrawn. As of December 31, 2014, we had no other significant off-balance sheet arrangements other than operating leases. For a description of our operating leases, see Note 9 to our consolidated financial statements in item 8. 37 Critical Accounting Estimates and Policies Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties, and potentially result in materially different results under different assumptions and conditions. Application of these policies is particularly important to the portrayal of our financial condition and results of operations. The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amount of assets, liabilities, revenues and expenses. Actual results may differ from these estimates under different assumptions or conditions. Our significant accounting policies, including the critical policies listed below, are more fully described in the notes to our consolidated financial statements included in this report. Revenue Recognition and Cost Estimation We recognize revenues when persuasive evidence of an arrangement exists, services have been rendered, the contract price is fixed or determinable and collectability is reasonably assured. We have a standard internal process that we use to determine whether all required criteria for revenue recognition have been met. Our revenues consist primarily of services provided by our employees and the pass through of costs for materials and subcontract efforts under contracts with our customers. Cost of services consists primarily of compensation expenses for program personnel, the fringe benefits associated with this compensation and other direct expenses incurred to complete programs, including cost of materials and subcontract efforts. We derive the majority of our revenues from cost-plus-fixed-fee, cost-plus-award-fee, firm-fixed-price or time-and-materials contracts. Revenues for cost-reimbursable contracts are recorded as reimbursable costs are incurred, including an estimated share of the applicable contractual fees earned. For performance-based fees under cost-reimbursable contracts, we recognize the relevant portion of the expected fee to be awarded by the customer at the time such fee can be reasonably estimated, based on factors such as our prior award experience and communications with the customer regarding performance, or upon approval by the customer. For time-and-materials contracts, revenues are recognized to the extent of billable rates times hours delivered plus materials and other reimbursable costs incurred. For long-term fixed-price production contracts, revenues are recognized at a rate per unit as the units are delivered or by other methods to measure services provided. Revenues from other long-term fixed-price contracts are recognized ratably over the contract period or by other appropriate methods to measure services provided. Contract costs are expensed as incurred except for certain limited long-term contracts noted below. For long-term contracts, specifically described in the scope section of ASC 605-35, we apply the percentage of completion method. Under the percentage of completion method, income is recognized at a consistent profit margin over the period of performance based on estimated profit margins at completion of the contract. This method of accounting requires estimating the total revenues and total contract cost at completion of the contract. During the performance of long-term contracts, these estimates are periodically reviewed and revisions are made as required using the cumulative catch-up method of accounting. The impact on revenues and contract profit as a result of these revisions is included in the periods in which the revisions are made. This method can result in the deferral of costs or the deferral of profit on these contracts. Because we assume the risk of performing a fixed-price contract at a set price, the failure to accurately estimate ultimate costs or to control costs during performance of the work could result, and in some instances has resulted, in reduced profits or losses for such contracts. Both the individual changes in contract estimates and aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting were not material to the consolidated statement of operations for all periods presented. Estimated losses on contracts at completion are recognized when identified. In certain circumstances, revenues are recognized when contract amendments have not been finalized. Accounting for Business Combinations, Goodwill and Other Intangible Assets The purchase price of an acquired business is allocated to the tangible assets, financial assets and separately recognized intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as goodwill. Such fair value assessments require judgments and estimates that can be affected by contract performance and other factors over time, which may cause final amounts to differ materially from original estimates. We review goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying value of long-lived assets may not be fully recoverable. We perform this review at the reporting unit level, which is one level below our one reportable segment. The goodwill impairment test is a two-step process performed at the reporting unit level. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (including goodwill). If the reporting unit's fair value exceeds its carrying value, no further procedures are required. However, if the reporting unit's fair value is less than its carrying value, an impairment of goodwill may exist, requiring a second step to be performed. Step two of 38 this test measures the amount of the impairment loss, if any. Step two of this test requires the allocation of the reporting unit's fair value to its assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill as if the reporting unit were being acquired in a business combination. If the implied fair value of goodwill is less than the carrying value, the difference is recorded as a goodwill impairment charge in operations. The fair values of the reporting units are determined based on a weighting of the income approach, market approach and market transaction approach. The income approach is a valuation technique in which fair value is based from forecasted future cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and debt capital as of the valuation date. The forecast used in our estimation of fair value was developed by management based on a contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty in government spending, pricing pressure and opportunities). The discount rate utilizes a risk adjusted weighted average cost of capital. The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an actual arm's length transaction. The technique consists of undertaking a detailed market analysis of publicly traded companies that provides a reasonable basis for comparison to the Company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the Company after consideration of adjustments for financial position, growth, market, profitability and other factors. The market transaction approach is a valuation technique in which the fair value is calculated based on market prices realized in actual arm's length transactions. The technique consists of undertaking a detailed market analysis of merged and acquired companies that provided a reasonable basis for comparison to the Company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the Company after consideration of adjustments for financial position, growth, market, profitability and other factors. To assess the reasonableness of the calculated reporting unit fair values, we compare the sum of the reporting units' fair values to the Company's market capitalization (per share stock price times the number of shares outstanding) and calculate an implied control premium (the excess of the sum of the reporting units' fair values over the market capitalization), and then assess the reasonableness of our implied control premium. Historically, we have elected to perform this review as of June 30th of each calendar year. During the fourth quarter of 2014, we changed the date of our annual goodwill impairment test to October 31st. The change in the annual goodwill impairment testing date is deemed a change in accounting principle, which we believe to be preferable. The change was made to better align with our customers' fiscal year, our year end reporting cycle as well as our annual planning and budgeting process, which is a significant element in the annual goodwill impairment test. This change in accounting principle did not delay, accelerate or avoid a goodwill impairment charge. The goodwill impairment test was performed on June 30, 2014 and on October 31, 2014 such that a period greater than 12 months did not elapse between test dates. The change in the annual goodwill impairment testing date was applied prospectively beginning on October 31, 2014 and had no effect on our consolidated financial statements. This change was not applied retrospectively as it is impracticable to do so because retrospective application would have required the application of significant estimates and assumptions without the use of hindsight. The results of our annual goodwill impairment test as of October 31, 2014 indicated that the estimated fair value of each reporting unit substantially exceeded its respective carrying value. In addition, management monitors events and circumstances that could result in an impairment. A significant amount of judgment is involved in determining if an indicator of impairment has occurred between annual testing dates. Events that could cause the fair value of our long-lived assets to decrease include: changes in our business environment or market conditions; a material change in our financial outlook, including declines in expected revenue growth rates and operating margins; or a material decline in the market price for our stock. If any impairment were indicated as a result of a review, we would recognize a loss based on the amount by which the carrying amount exceeds the estimated fair value. Due to the many variables inherent in the estimation of a reporting unit's fair value and the relative size of our recorded goodwill, differences in assumptions may have a material effect on the results of our goodwill impairment analysis. Accounting Standards Updates In January 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20) - Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items, which eliminates from GAAP the concept of extraordinary items. The Board concluded that the amendments in this ASU will not result in a loss of information because although the amendments will eliminate the requirements in Subtopic 225-20 for reporting entities to consider whether an underlying event or transaction is extraordinary, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The ASU is effective for annual periods ending after December 15, 2015, and interim periods thereafter. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The adoption of ASU 2015-01 is not expected to have a material impact on our results of operations, financial position or cash flows. 39 On August 27, 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern, which provides guidance on determining when and how reporting entities must disclose going-concern uncertainties in their financial statements. The new standard requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date of issuance of an entity's financial statements. Further, an entity must provide certain disclosures if there is substantial doubt about the entity's ability to continue as a going concern. The ASU is effective for annual periods ending after December 15, 2016, and interim periods thereafter; early adoption is permitted. The adoption of ASU 2014-15 is not expected to have a material impact on our results of operations, financial position or cash flows. On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 supersedes existing revenue recognition guidance, including Accounting Standards Codification (ASC) No. 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts. ASU 2014-09 outlines a single set of comprehensive principles for recognizing revenue under U.S. GAAP. Among other things, it requires companies to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time. These concepts, as well as other aspects of ASU 2014-09, may change the method and/or timing of revenue recognition for certain of our contracts. ASU 2014-09 will be effective January 1, 2017, and may be applied either retrospectively or through the use of a modified-retrospective method. We are currently evaluating both methods of adoption as well as the effect ASU 2014-09 will have on our consolidated financial statements. On April 10, 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which amends the definition of a discontinued operation in ASC 205-20 and requires entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued-operations criteria. The ASU is effective prospectively for all disposals (except disposals classified as held for sale before the adoption date) or components initially as held for sale in periods beginning on or after December 15, 2014. Early adoption is permitted. The adoption of ASU 2014-08 is not expected to have a material impact on our results of operations, financial position or cash flows. Contractual Obligations Our contractual obligations as of December 31, 2014 are as follows (in thousands): Payments Due By Period Contractual Obligations Operating lease obligations (1) Other long-term liabilities (2) Accrued defined benefit obligations (3) Total Total Less than 1 Year 1-3 Years 3-5 Years More than 5 Years $ $ 164,161 $ 28,768 $ 47,373 $ 40,693 $ 12,122 1,293 1,255 136 1,521 262 3,058 247 47,327 6,288 648 177,576 $ 30,159 $ 49,156 $ 43,998 $ 54,263 (1) Excludes approximately $11.1 million of deferred rent liabilities. See Note 9 to our consolidated financial statements in Item 8 for additional information regarding operating leases. (2) Includes approximately $11.1 million of deferred rent liabilities as well as gross unrecognized tax benefits of $0.8 million. See Note 9 to our consolidated financial statements in Item 8 for additional information regarding deferred rent liabilities. See Note 12 to our consolidated financial statements in Item 8 for additional information regarding gross unrecognized tax benefits. (3) Includes approximately $1.3 million of unfunded pension obligations related to nonqualified supplemental defined benefit pension plans for certain retired employees of an acquired company, which is included in the accrued retirement amount on our consolidated balance sheets. Excludes liabilities related to one non-qualified deferred compensation plan for certain highly compensated employees, which are included in the accrued retirement amount on our consolidated balance sheets. The funds deferred by the employees are invested and maintained in rabbi trusts, which are reflected in the employee supplemental savings plan assets on our consolidated balance sheets. These liabilities will be satisfied by assets held in rabbi trusts. See Note 11 to our consolidated financial statements in Item 8 for additional information regarding retirement plans. Item 7A. Quantitative and Qualitative Disclosures about Market Risk Our exposure to market risk relates to changes in interest rates for borrowings under our revolving credit facility. At December 31, 2014, we had no outstanding balance on our revolving credit facility. Borrowings under our revolving credit facility bear interest at variable rates. A hypothetical 10% increase in interest rates would have increased our interest expense by $7 thousand for the year ended December 31, 2014. 40 We do not use derivative financial instruments for speculative or trading purposes. When we have excess cash, we invest in short-term, investment grade, interest-bearing securities. Our investments are made in accordance with an investment policy. Under this policy, no investment security can have a maturity exceeding six months and the weighted average maturity of the portfolio cannot exceed 60 days. 41 Item 8. Financial Statements and Supplementary Data Index to Consolidated Financial Statements Report of Independent Registered Public Accounting Firm Consolidated Balance Sheets as of December 31, 2014 and 2013 Consolidated Statements of Income and Loss for the years ended December 31, 2014, 2013 and 2012 Consolidated Statements of Comprehensive Income and Loss for the years ended December 31, 2014, 2013 and 2012 Consolidated Statements of Changes in Stockholders' Equity for the years ended December 31, 2014, 2013 and 2012 Consolidated Statements of Cash Flows for the years ended December 31, 2014, 2013 and 2012 Notes to Consolidated Financial Statements Page(s) 43 44 45 46 47 48 49 42 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders of ManTech International Corporation Fairfax, Virginia We have audited the accompanying consolidated balance sheets of ManTech International Corporation and subsidiaries (the "Company") as of December 31, 2014 and 2013, and the related consolidated statements of income and loss, comprehensive income and loss, changes in stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2014. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits. We conducted our audits 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 the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of ManTech International Corporation and subsidiaries as of December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control- Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 20, 2015 expressed an unqualified opinion on the Company's internal control over financial reporting. /s/ DELOITTE & TOUCHE LLP McLean, Virginia February 20, 2015 43 MANTECH INTERNATIONAL CORPORATION

Description of the Business ManTech International Corporation (depending on the circumstances, “ManTech” “Company” “we” “our” “ours” or “us”) is a leading provider of innovative technologies and solutions for mission-critical national security programs for the intelligence community; the departments of Defense, State, Homeland Security, Health and Human Services, Veteran Affairs, and Justice, including the Federal Bureau of Investigation (FBI); the space communities; and other U.S. government customers. We provide support to critical national security programs for approximately 50 federal agencies through approximately 1,100 current contracts. Our expertise includes cyber; software and systems development; enterprise information technology; multi-discipline intelligence; program protection and mission assurance; systems engineering; test and evaluation (T&E); command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR); training; global logistics and supply chain management; and management consulting. We support major national missions, such as military readiness and wellness, terrorist threat detection, information security and border protection. Our employees operate primarily in the United States, as well as numerous locations internationally. 2. Summary of Significant Accounting Policies Principles of Consolidation-Our consolidated financial statements include the accounts of ManTech International Corporation, subsidiaries we control and variable interest entities that are required to be consolidated. All intercompany accounts and transactions have been eliminated. Investments in entities where we have significant influence, but not control, are accounted for using the equity method. Use of Accounting Estimates-We prepare our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates involve judgments with respect to, among other things, various future economic factors that are difficult to predict and are beyond the control of the Company. Therefore, actual amounts could differ from these estimates. Revenue Recognition-We derive the majority of our revenues from cost-plus-fixed-fee, cost-plus-award-fee, firm-fixed-price or time-and-materials contracts. Revenues for cost-reimbursable contracts are recorded as reimbursable costs are incurred, including an estimated share of the applicable contractual fees earned. For performance-based fees under cost-reimbursable contracts, we recognize the relevant portion of the expected fee to be awarded by the customer at the time such fee can be reasonably estimated, based on factors such as our prior award experience and communications with the customer regarding performance, or upon approval by the customer. For time-and-materials contracts, revenues are recognized to the extent of billable rates times hours delivered plus materials and other reimbursable costs incurred. For long-term fixed-price production contracts, revenues are recognized at a rate per unit as the units are delivered or by other methods to measure services provided. Revenues from other long-term fixed-price contracts are recognized ratably over the contract period or by other appropriate methods to measure services provided. Contract costs are expensed as incurred except for certain limited long-term contracts noted below. For long-term contracts, specifically described in the scope section of ASC 605-35, we apply the percentage of completion method. Under the percentage of completion method, income is recognized at a consistent profit margin over the period of performance based on estimated profit margins at completion of the contract. This method of accounting requires estimating the total revenues and total contract cost at completion of the contract. During the performance of long-term contracts, these estimates are periodically reviewed and revisions are made as required using the cumulative catch-up method of accounting. The impact on revenues and contract profit as a result of these revisions is included in the periods in which the revisions are made. This method can result in the deferral of costs or the deferral of profit on these contracts. Because we assume the risk of performing a fixed-price contract at a set price, the failure to accurately estimate ultimate costs or to control costs during performance of the work could result, and in some instances has resulted, in reduced profits or losses for such contracts. Both the individual changes in contract estimates and aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting were not material to the consolidated statement of operations for all periods presented. Estimated losses on contracts at completion are recognized when identified. In certain circumstances, revenues are recognized when contract amendments have not been finalized. Cost of Services-Cost of services consists primarily of compensation expenses for program personnel, the fringe benefits associated with this compensation and other direct expenses incurred to complete programs, including cost of materials and subcontract efforts. 49 General and Administrative Expenses-General and administrative expenses include the salaries and wages, plus associated fringe benefits of our employees not performing work directly for customers, and associated facilities costs. Among the functions covered by these costs are corporate business development, bid and proposal, contracts administration, finance and accounting, legal, corporate governance and executive and senior management. In addition, we included stock-based compensation, as well as depreciation and amortization expenses related to the general and administrative function. We classify indirect costs incurred as cost of services and general and administrative expenses in the same manner as such costs are defined in our disclosure statements under U.S. Government Cost Accounting Standards. Effective January 1, 2014, we updated our disclosure statements with the Defense Contract Management Agency, resulting in certain costs being classified differently either as cost of services or as general and administrative expenses on a prospective basis. This change has caused a net increase in the reported cost of services and a net decrease in reported general and administrative expenses in 2014 as compared to 2013 and 2012; however, total operating costs were not affected by this change. Cash and Cash Equivalents-For the purpose of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks and short-term investments with maturity dates of three months or less at the date of purchase. Due to the short maturity of cash equivalents, the carrying value on our consolidated balance sheets approximates fair value. Property and Equipment-Property and equipment are recorded at original cost to the Company. Upon sale or retirement, the costs and related accumulated depreciation or amortization are eliminated from the respective accounts and any resulting gain or loss is included in income. Maintenance and repairs are charged to expense as incurred. Depreciation and Amortization Method-Furniture and office equipment are depreciated using the straight-line method with estimated useful lives ranging from one to seven years. Leasehold improvements are amortized using the straight-line method over the term of the lease. Contractual Inventory-Inventory consists of finished goods purchased for a specific contract. Goodwill-The purchase price of an acquired business is allocated to the tangible assets, financial assets and separately recognized intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as goodwill. We review goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying value of long-lived assets may not be fully recoverable. Historically, we have elected to perform this review as of June 30th of each calendar year. During the fourth quarter of 2014, we changed the date of our annual goodwill impairment test to October 31st. The change in the annual goodwill impairment testing date is deemed a change in accounting principle, which we believe to be preferable. The change was made to better align with our customers' fiscal year, our year end reporting cycle as well as our annual planning and budgeting process, which is a significant element in the annual goodwill impairment test. This change in accounting principle did not delay, accelerate or avoid a goodwill impairment charge. The annual goodwill impairment test was performed on June 30, 2014 and on October 31, 2014 such that a period greater than 12 months did not elapse between test dates. The change in the annual goodwill impairment testing date was applied prospectively beginning on October 31, 2014 and had no effect on our consolidated financial statements. This change was not applied retrospectively as it is impracticable to do so because retrospective application would have required the application of significant estimates and assumptions without the use of hindsight. If any impairment was indicated as a result of a review, we would recognize a loss based on the amount by which the carrying amount exceeds the estimated fair value. Other Intangible Assets-Contract rights and other intangible assets are amortized primarily using the pattern of benefits method over periods ranging from one to twenty-five years. We accounted for the cost of computer software developed or obtained for internal use in accordance with ASC 350-985, Software. These capitalized software costs are included in other intangible assets, net. We account for software development costs related to software products for sale, lease or otherwise marketed in accordance with ASC 985-20, Costs of Software to be Sold, Leased, or Marketed. For projects fully funded by us, development costs are capitalized from the point of demonstrated technological feasibility until the point in time that the product is available for general release to customers. Once the product is available for general release, capitalized costs are amortized based on units sold or on a straight-line basis over a five-year period or other such shorter period as may be required. Impairment of Long-Lived Assets-Whenever events or changes in circumstances indicate that the carrying amount of long- lived assets may not be fully recoverable, we evaluate the probability that future undiscounted net cash flows, without interest 50 charges, will be less than the carrying amount of the assets. If any impairment were indicated as a result of this review, we would recognize a loss based on the amount by which the carrying amount exceeds the estimated fair value. Employee Supplemental Savings Plan Assets-We maintain several non-qualified defined contribution supplemental retirement plans for certain key employees that are accounted for in accordance with ASC 710-10-05, Deferred Compensation - Rabbi Trusts, as the underlying assets are held in rabbi trusts with investments directed by the respective employee. A rabbi trust is a grantor trust generally set up to fund compensation for a select group of management and the assets of this trust are available to satisfy the claims of general creditors in the event of bankruptcy of the Company. The assets held by the rabbi trusts are recorded at cash surrender value in our consolidated financial statements as Employee Supplemental Savings Plan assets with a related liability to employees recorded as a deferred compensation liability in accrued retirement. Billings In Excess of Revenue Earned-We receive advances and milestone payments from customers that exceed the revenues earned to date. We classify such items as current liabilities. Stock-based Compensation-We account for stock-based compensation in accordance with ASC 718, Compensation - Stock Compensation. ASC 718 requires the use of a valuation model to calculate the fair value of stock-based awards. We have elected to use the Black-Scholes-Merton pricing model to determine fair value on the dates of grant. The fair value is included in operating expenses or capitalized, as appropriate, straight-line over the period in which service is provided in exchange for the award. Income Taxes-We account for income taxes in accordance with ASC 740, Income Taxes. Under this method, deferred income taxes are determined based on the estimated future tax effects of differences between the financial statement and tax bases of assets and liabilities given the provisions of enacted tax laws. Deferred income tax provisions and benefits are based on changes to the assets or liabilities from year-to-year. In providing for deferred taxes, we consider tax regulations of the jurisdictions in which we operate, estimates of future taxable income and available tax planning strategies. If tax regulations, operating results or the ability to implement tax-planning strategies vary, adjustments to the carrying value of deferred tax assets and liabilities may be required. Valuation allowances are recorded related to deferred tax assets based on the “more likely than not” criteria. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would “more likely than not” sustain the position following an audit. For tax positions meeting the “more likely than not” threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. Foreign-Currency Translation-All assets and liabilities of foreign subsidiaries are translated into U.S. dollars at fiscal year- end exchange rates. Income and expense items are translated at average monthly exchange rates prevailing during the fiscal year. The resulting translation adjustments are recorded as a component of accumulated other comprehensive income (loss). Comprehensive Income (Loss)-Comprehensive income (loss) is presented in our consolidated statements of changes in stockholders' equity. Comprehensive income (loss) consists of net income (loss); translation adjustments, net of tax; and actuarial gain (loss) on defined benefit pension plan, net of tax. Fair Value of Financial Instruments-The carrying value of our cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair value because of the short-term nature of these amounts. Variable Interest Entities-We determine whether we have a controlling financial interest in a Variable Interest Entity (VIE). The reporting entity with a variable interest or interest that provides the reporting entity with a controlling financial interest in a VIE will have both (a) the power to direct the activities of a VIE that most significantly impact the VIE's economic performance and (b) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. We have one entity that has been consolidated as a VIE. The purpose of the entity is to perform on certain U.S. Navy contracts. The maximum amount of loss we are exposed to as of December 31, 2014 was not material to our consolidated financial statements. Equity Method Investments-Investments where we have the ability to exercise significant influence, but we do not control, are accounted for under the equity method of accounting and are included in other assets on our consolidated balance sheets. Significant influence typically exists if we have a 20% to 50% ownership interest in the investee. Under this method of accounting, our share of the net earnings or losses of the investee is included in equity in earnings or losses of unconsolidated subsidiaries on our consolidated statement of income and loss. 51 Accounting Standards Updates In January 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20) - Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items, which eliminates from GAAP the concept of extraordinary items. The Board concluded that the amendments in this ASU will not result in a loss of information because although the amendments will eliminate the requirements in Subtopic 225-20 for reporting entities to consider whether an underlying event or transaction is extraordinary, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The ASU is effective for annual periods ending after December 15, 2015, and interim periods thereafter. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The adoption of ASU 2015-01 is not expected to have a material impact on our results of operations, financial position or cash flows. On August 27, 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-15, Presentation of Financial Statements - Going Concern, which provides guidance on determining when and how reporting entities must disclose going-concern uncertainties in their financial statements. The new standard requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date of issuance of an entity's financial statements. Further, an entity must provide certain disclosures if there is substantial doubt about the entity's ability to continue as a going concern. The ASU is effective for annual periods ending after December 15, 2016, and interim periods thereafter; early adoption is permitted. The adoption of ASU 2014-15 is not expected to have a material impact on our results of operations, financial position or cash flows. On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 supersedes existing revenue recognition guidance, including Accounting Standards Codification (ASC) No. 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts. ASU 2014-09 outlines a single set of comprehensive principles for recognizing revenue under U.S. GAAP. Among other things, it requires companies to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time. These concepts, as well as other aspects of ASU 2014-09, may change the method and/or timing of revenue recognition for certain of our contracts. ASU 2014-09 will be effective January 1, 2017, and may be applied either retrospectively or through the use of a modified-retrospective method. We are currently evaluating both methods of adoption as well as the effect ASU 2014-09 will have on our consolidated financial statements. On April 10, 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which amends the definition of a discontinued operation in ASC 205-20 and requires entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued-operations criteria. The ASU is effective prospectively for all disposals (except disposals classified as held for sale before the adoption date) or components initially as held for sale in periods beginning on or after December 15, 2014. Early adoption is permitted. The adoption of ASU 2014-08 is not expected to have a material impact on our results of operations, financial position or cash flows. 3. Acquisitions 7Delta Inc.-On May 23, 2014, we completed the acquisition of all equity interests in 7Delta Inc. (7Delta). The results of 7Delta's operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated May 23, 2014, by and among ManTech International Corporation, 7Delta, SLS Holdings, Inc. and the stockholders of SLS Holdings, Inc. 7Delta performs critical services such as applications and software development, program management, systems integration, information assurance and security architecture primarily within the healthcare community at the Department of Veteran Affairs (VA). We funded the acquisition through a combination of cash on hand and borrowings under our revolving credit facility. The stock purchase agreement did not contain provisions for contingent consideration. For the year ended December 31, 2014, ManTech incurred approximately $0.5 million of acquisition costs related to the 7Delta transaction, which are included in the general and administrative expenses in our consolidated statement of income. The purchase price of $81.4 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The purchase price allocation for 7Delta is not complete as of December 31, 2014 since acquired receivables and assumed accounts payables and accrued expenses continue to be evaluated. We preliminarily recorded goodwill of $70.0 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition 52 of goodwill is largely attributed to the value paid for 7Delta's capabilities in providing software development, program management, system integration, information assurance and security architecture to the VA. In preliminarily allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of 7Delta's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $4.8 million and $2.9 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with 7Delta's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful life of approximately 10 years. Backlog is amortized straight-line over its estimated useful life of 2 years. The weighted-average amortization period for the intangible assets is 7 years. The following table represents the preliminary purchase price allocation for 7Delta (in thousands): Cash and cash equivalents Receivables Prepaid expenses and other Goodwill Other intangible assets Property and equipment Other assets Accounts payable and accrued expenses Accrued salaries and related expenses Billings in excess of revenue earned Net assets acquired and liabilities assumed 7Delta Inc. $ $ 1,408 9,664 175 69,967 7,762 597 39 (6,617) (1,399) (229) 81,367 We have not disclosed current period, nor pro forma, revenues and earnings attributable to 7Delta as our integration of these operations post acquisition and the entity's accounting methods preacquisition make it impracticable. Allied Technology Group, Inc.-On February 18, 2014, we completed the acquisition of all equity interests in Allied Technology Group, Inc. (ATG). The results of ATG's operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated February 18, 2014, by and among ManTech Advanced Systems International, Inc., Allied Technology Group, Inc. and the stockholders of ATG. ATG is an innovative engineering and information management solution company with strong customer relationships and strategic contracts with the Department of Homeland Security (DHS). ATG provides IT, engineering services, program management and training solutions to a variety of federal customers. The acquisition will enable us to deliver services through their unrestricted prime position on DHS's primary acquisition vehicles: Technical, Acquisition and Business Support Services and Enterprise Acquisition Gateway for Leading Edge Solutions II. We funded the acquisition with cash on hand. The stock purchase agreement did not contain provisions for contingent consideration. For the year ended December 31, 2014, ManTech incurred approximately $0.4 million of acquisition costs related to the ATG transaction, which are included in the general and administrative expenses in our consolidated statement of income. The purchase price of $45.0 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. We recorded goodwill of $28.8 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for ATG's capabilities in providing technology service program management, systems engineering and information technology services to DHS. In allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of ATG's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $6.4 million and $0.6 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with ATG's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful life of approximately 20 years. Backlog is amortized straight-line over its estimated useful life of 1 year. The weighted-average amortization period for the intangible assets is 18 years. 53 The following table represents the purchase price allocation for ATG (in thousands): Allied Technology Group, Inc.

ALTA Systems, Inc.-On January 8, 2013, we completed the acquisition of ALTA Systems, Inc. (ALTA). The results of ALTA's operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated January 8, 2013, by and among ManTech International Corporation, ALTA Holdings LLC and the sole member of ALTA Holding LLC. ALTA is an information technology (IT) and professional services company with valuable applications in healthcare systems and capital planning. ALTA provides a broad range of IT and professional services to government and private industry in three major areas: capital planning and investment control; system design, development and operations; and fraud detection and statistical analysis. The acquisition allows ManTech to deliver technology services through ALTA's prime position on the Centers of Medicare and Medicaid Services (CMS) Enterprise Systems Development (ESD) contract. ManTech funded the acquisition with cash on hand. The stock purchase agreement did not contain provisions for contingent consideration. For the year ended December 31, 2013, ManTech incurred approximately $0.1 million of acquisition costs related to the ALTA transaction, which are included in the general and administrative expenses in our consolidated statement of loss and no acquisition costs were recorded after 2013. The purchase price of $10.2 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. We have recorded total assets of $11.1 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities of $0.9 million. Included in total assets were $0.7 million in acquisition related intangible assets. We recorded goodwill of $9.1 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for ALTA's capabilities in providing technology services to the U.S. government in the health care sector. In allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of ALTA's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $0.6 million and $0.1 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with ALTA's existing customers. Customer relationships and backlog are amortized straight-line over their estimated useful lives of approximately 20 years and 1 year, respectively. The weighted-average amortization period for the intangible assets is 17 years. We have not disclosed current period, nor pro forma, revenues and earnings attributable to ALTA as our integration of these operations post acquisition and the entity's accounting methods preacquisition make it impracticable. HBGary, Inc.-On April 2, 2012, we completed the acquisition of certain assets of HBGary, Inc. (HBGary). The results of HBGary's operations have been included in our consolidated financial statements since that date. The acquisition was completed through an asset purchase agreement dated February 27, 2012, by and among a subsidiary of ManTech International Corporation, HBGary and the shareholders of HBGary. HBGary provides a comprehensive suite of software products to detect, analyze and diagnose Advance Persistent Threats and targeted malware. The company has customers in the financial services, energy, critical 54 infrastructure and technology sectors. This acquisition broadened our cyber security solution capability for customers. ManTech funded the acquisition with cash on hand. The asset purchase agreement did not contain provisions for contingent consideration. For the year ended December 31, 2012, ManTech incurred approximately $0.8 million of acquisition costs related to the HBGary transaction, which are included in the general and administrative expenses in our consolidated statement of income and no acquisition costs were recorded after 2012. The purchase price of $23.8 million was allocated to the underlying assets and liabilities based on their fair value at the date of acquisition. Total assets were $24.6 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $0.8 million. Included in total assets were $3.1 million in acquisition related intangible assets. We recorded goodwill of $20.1 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for HBGary's capabilities in providing cyber service and product solutions to both federal and commercial customers. The components of other intangible assets associated with the acquisition were developed technology, customer relationships and trademark valued at $2.0 million, $0.9 million and $0.2 million, respectively. Developed technology represents the software developed by HBGary to detect, analyze and diagnose Advanced Persistent Threats and targeted malware. Customer relationships represent the underlying relationship with HBGary customers in the financial services, energy, critical infrastructure and technology sectors. Trademark represents the HBGary trade name that is recognized in the industry. Developed technology, customer relationships and trademark are amortized straight-line over their estimated useful lives of approximately 3 years, 2 years and 2 years, respectively. The weighted-average amortization period for the intangible assets is 3 years. We have not disclosed current period, nor pro forma, revenues and earnings attributable to HBGary as our integration of these operations post acquisition and the entity's accounting methods preacquisition make it impracticable. Evolvent Technologies, Inc.-On January 6, 2012, we completed the acquisition of Evolvent Technologies, Inc. (Evolvent). The results of Evolvent's operations have been included in our consolidated financial statements since that date. The acquisition was completed through an equity purchase agreement dated January 6, 2012, by and among ManTech, shareholders and warrantholders of the parent of Evolvent, Evolvent and Prudent Management, LLC in its capacity as the sellers' representative. Evolvent provides services in clinical IT, clinical business intelligence, imaging cyber security, behavioral health, tele-health, software development and systems integration. Its systems and processes enable better decision-making at the point of care and full integration of medical information across different platforms. This acquisition has enabled ManTech to expand its customer relationships and deliver IT solutions through Evolvent's existing relationships with the Department of Defense health organizations, the Veterans Administration and the Department of Health and Human Services. ManTech funded the acquisition with cash on hand. The equity purchase agreement did not contain provisions for contingent consideration. For the year ended December 31, 2012, the Company incurred $0.2 million of acquisition costs associated with the Evolvent transaction, which are included in general and administrative expenses in our consolidated statement of income and no acquisition costs were recorded after 2012. The purchase price of $39.9 million was allocated to the underlying assets and liabilities based on their fair value at the date of acquisition. Total assets were $46.9 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities were $7.0 million. Included in total assets were $3.7 million in acquisition related intangible assets. We recorded goodwill of $33.2 million, which is not deductible for tax purposes. Recognition of goodwill is largely attributed to the highly skilled employees and the value paid for Evolvent's capabilities in providing IT services and solutions to the U.S. government healthcare sector. In allocating the purchase price, we considered among other factors, analyses of historical performance and estimates of future performance of Evolvent's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $3.4 million and $0.3 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with Evolvent's existing customers. Customer relationships and backlog are amortized over their estimated useful lives of 20 years and 1 year, respectively, using the pattern of benefits method. The weighted-average amortization period for the intangible assets is 19 years. We have not disclosed current period, nor pro forma, revenues and earnings attributable to Evolvent as our integration of these operations post acquisition and the entity's accounting methods preacquisition make it impracticable. 55 4. Earnings (Loss) per Share Under ASC 260, Earnings per Share, the two-class method is an earnings (loss) allocation formula that determines earnings (loss) per share for each class of common stock according to dividends declared (or accumulated) and participation rights in undistributed earnings (loss). Under that method, basic and diluted earnings (loss) per share data are presented for each class of common stock. In applying the two-class method, we determined that undistributed earnings (loss) should be allocated equally on a per share basis between Class A and Class B common stock. Under our Certificate of Incorporation, the holders of the common stock are entitled to participate ratably, on a share-for-share basis as if all shares of common stock were of a single class, in such dividends, as may be declared by the Board of Directors. During the years ended December 31, 2014, 2013 and 2012, we declared and paid quarterly dividends, each in the amount of $0.21 per share on both classes of common stock. Basic earnings (loss) per share has been computed by dividing net income (loss) available to common stockholders by the weighted average number of shares of common stock outstanding during each period. Shares issued during the period and shares reacquired during the period are weighted for the portion of the period in which the shares were outstanding. Diluted earnings (loss) per share have been computed in a manner consistent with that of basic earnings (loss) per share while giving effect to all potentially dilutive common shares that were outstanding during each period. The net income (loss) available to common stockholders and weighted average number of common shares outstanding used to compute basic and diluted earnings (loss) per share for each class of common stock are as follows (in thousands, except per share amounts): Distributed earnings Undistributed earnings (loss) Net income (loss) Class A common stock: Basic net income (loss) available to common stockholders Basic weighted average common shares outstanding Basic earnings (loss) per share Diluted net income (loss) available to common stockholders Effect of potential exercise of stock options Diluted weighted average common shares outstanding Diluted earnings (loss) per share Class B common stock: Basic net income (loss) available to common stockholders Basic weighted average common shares outstanding Basic earnings (loss) per share Diluted net income (loss) available to common stockholders Effect of potential exercise of stock options Diluted weighted average common shares outstanding Diluted earnings (loss) per share Year Ended December 31, 2013 $ $ $ $ $ $ $ $ $ $ 31,200 (37,349) (6,149) $ (3,963) $ 23,913 (0.17) $ (3,963) $ — 23,913 (0.17) $ (2,186) $ 13,193 (0.17) $ (2,186) $ — 13,193 2014 31,313 15,981 47,294 30,539 24,047 1.27 30,571 70 24,117 1.27 16,755 13,193 1.27 16,723 — 13,193 1.27 $ (0.17) $ $ $ $ $ $ $ $ $ $ $ 2012 31,050 63,969 95,019 61,065 23,727 2.57 61,103 41 23,768 2.57 33,954 13,193 2.57 33,916 — 13,193 2.57 For the years ended December 31, 2014, 2013 and 2012, options to purchase 2.7 million, 3.2 million and 2.9 million shares, respectively, were outstanding but not included in the computation of diluted earnings (loss) per share because the options' effect 56 would have been anti-dilutive. For the years ended December 31, 2014, 2013 and 2012, there were 158,371 shares, 79,567 shares, and 38,542 shares, respectively, issued from the exercise of stock options. 5. Receivables We deliver a broad array of information technology and technical services solutions under contracts with the U.S. government, state and local governments and commercial customers. The components of contract receivables are as follows (in thousands): Billed receivables Unbilled receivables: Amounts billable Revenues recorded in excess of funding Retainage Allowance for doubtful accounts Receivables-net December 31, 2014 2013 $ 319,065 $ 370,975 50,393 13,082 4,446 (9,830) 377,156 $ 84,582 9,743 2,634 (10,036) 457,898 $ Amounts billable consist principally of amounts to be billed within the next month. Revenues recorded in excess of funding are billable upon receipt of contractual amendments or other modifications. The retainage is billable upon completion of the contract performance and approval of final indirect expense rates by the government. There is a contract with the U.S. Army that represents 2.2% and 15.3% of receivables-net at December 31, 2014 and 2013, respectively. Accounts receivable at December 31, 2014 are expected to be substantially collected within one year except for approximately $1.1 million, of which 89.1% is related to receivables from sales to the U.S. government. The remainder is related to receivables from contracts in which we acted as a subcontractor to other contractors. The Company does not believe it has significant exposure to credit risk as accounts receivable and the related unbilled amounts are primarily due from the U.S. government. The allowance for doubtful accounts represents our estimate for exposure to compliance, contractual issues and bad debts related to prime contractors. 6. Property and Equipment Major classes of property and equipment are summarized as follows (in thousands): Furniture and equipment Leasehold improvements Property and equipment-gross Accumulated depreciation and amortization Property and equipment-net December 31, 2014 2013 $ $ 43,659 $ 35,601 79,260 (53,517) 25,743 $ 50,989 33,535 84,524 (54,368) 30,156 Depreciation and amortization expense related to property and equipment for the years ended December 31, 2014, 2013 and 2012 was $9.0 million, $8.7 million and $30.9 million, respectively. 7. Goodwill and Other Intangible Assets Under ASC 350, Intangibles - Goodwill and Other, goodwill is to be reviewed at least annually for impairment and whenever events or circumstances indicate that the carrying value of goodwill may not be fully recoverable. Historically, we have elected to perform this review as of June 30th of each calendar year. During the fourth quarter of 2014, we changed the date of our annual goodwill impairment test to October 31st. The change in the annual goodwill impairment testing date is deemed a change in accounting principle, which we believe to be preferable. The change was made to better align with our customers' fiscal year, our year end reporting cycle as well as our annual planning and budgeting process, which is a significant element in the annual goodwill 57 impairment test. This change in accounting principle did not delay, accelerate or avoid a goodwill impairment charge. The goodwill impairment test was performed on June 30, 2014 and on October 31, 2014 such that a period greater than 12 months did not elapse between test dates. The change in the annual goodwill impairment testing date was applied prospectively beginning on October 31, 2014 and had no effect on our consolidated financial statements. This change was not applied retrospectively as it is impracticable to do so because retrospective application would have required the application of significant estimates and assumptions without the use of hindsight. In reviewing goodwill for impairment, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the estimated fair value of a reporting unit is less than its carrying amount. If we elect to perform a qualitative assessment and determine that an impairment is more likely than not, the entity is then required to perform the existing two-step quantitative impairment test (described below), otherwise no further analysis is required. We also may elect not to perform the qualitative assessment and, instead, proceed directly to the two- step quantitative impairment test. The goodwill impairment test is a two-step process performed at the reporting unit level. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (including goodwill). If the reporting unit's fair value exceeds its carrying value, no further procedures are required. However, if the reporting unit's fair value is less than its carrying value, an impairment of goodwill may exist, requiring a second step to be performed. Step two of this test measures the amount of the impairment loss, if any. Step two of this test requires the allocation of the reporting unit's fair value to its assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill as if the reporting unit were being acquired in a business combination. If the implied fair value of goodwill is less than the carrying value, the difference is recorded as a goodwill impairment charge in operations. The fair values of the reporting units are determined based on a weighting of the income approach, market approach and market transaction approach. The income approach is a valuation technique in which fair value is based from forecasted future cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and debt capital as of the valuation date. The forecast used in our estimation of fair value was developed by management based on a contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty in government spending, pricing pressure and opportunities). The discount rate utilizes a risk adjusted weighted average cost of capital. The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an actual arm's length transaction. The technique consists of undertaking a detailed market analysis of publicly traded companies that provides a reasonable basis for comparison to the Company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the Company after consideration of adjustments for financial position, growth, market, profitability and other factors. The market transaction approach is a valuation technique in which the fair value is calculated based on market prices realized in actual arm's length transactions. The technique consists of undertaking a detailed market analysis of merged and acquired companies that provided a reasonable basis for comparison to the Company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the Company after consideration of adjustments for financial position, growth, market, profitability and other factors. To assess the reasonableness of the calculated reporting unit fair values, we compare the sum of the reporting units' fair values to the Company's market capitalization (per share stock price times the number of shares outstanding) and calculate an implied control premium (the excess of the sum of the reporting units' fair values over the market capitalization) and then assess the reasonableness of our implied control premium. During the fourth quarter of 2013, multiple events and circumstances indicated a significant reduction in the operating performance outlook of one of our reporting units. These events included lower than expected contract awards on several competitive opportunities, changing mission priorities of the U.S. government in relation to our Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) contracts and Overseas Contingency Operations (OCO) related work, primarily on maintenance and sustainment of Mine-Resistant Ambush-Protected (MRAP) vehicles, delays in our customers' procurement cycle due, in part, to the U.S. government shutdown, and continued margin pressures on some of our contracts. The culmination of these events led us to conduct an interim goodwill impairment test. The results of step one of this test showed the carrying value of one reporting unit was in excess of its fair value, therefore we performed step two of the goodwill impairment test to measure the amount of the impairment loss. Based on the results of the step two analysis, we recorded a non-cash goodwill impairment charge of $118.4 million for the period ending December 31, 2013. 58 The changes in the carrying amounts of goodwill during fiscal years 2014 and 2013 were as follows (in thousands): Goodwill at December 31, 2012 Impairment Acquisitions Goodwill at December 31, 2013 Acquisitions Goodwill at December 31, 2014 $ Goodwill Balance 861,912 (118,427) 9,382 752,867 98,773 $ 851,640 Other intangible assets consisted of the following (in thousands): Other intangible assets: Contract and program intangible assets Capitalized software cost for internal use Other Total other intangible assets-net December 31, 2014 December 31, 2013 Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount $ 266,272 $ 126,619 $ 139,653 $ 251,572 $ 109,586 $ 141,986 35,036 115 $ 301,423 $ 19,500 54 146,173 15,536 61 $ 155,250 34,083 115 285,770 $ $ 23,617 44 133,247 $ 10,466 71 152,523 Amortization expense relating to intangible assets for the years ended December 31, 2014, 2013 and 2012 was $20.4 million, $20.4 million and $20.5 million, respectively. We estimate that we will have the following amortization expense for the future periods indicated below (in thousands): Year ending: December 31, 2015 December 31, 2016 December 31, 2017 December 31, 2018 December 31, 2019 8. Debt $18,839 $16,682 $14,705 $13,208 $11,354 Revolving Credit Facility-We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as sole administrative agent. The credit agreement provides for a $500 million revolving credit facility, with a $25 million letter of credit sublimit and a $30 million swing line loan sublimit. The credit agreement also includes an accordion feature that permits the Company to arrange with the lenders for the provision of additional commitments. On June 13, 2014, we amended and restated the credit agreement, and extended the maturity date to June 13, 2019. We deferred $3.4 million in debt issuance costs, cumulatively over the agreements, which are amortized over the term of the amended and restated credit agreement. Borrowings under our credit agreement are collateralized by substantially all the assets of ManTech and its Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by the Company at the time of borrowing: a London Interbank Offer Rate (LIBOR) based rate plus market spreads (1.25% to 2.25% based on our consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on our consolidated total leverage ratio). The aggregate annual weighted average interest rates were 0.76% and 0.00% for the years ended December 31, 2014 and 2013, respectively. 59 The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain conditions. The credit agreement requires the Company to comply with specified financial covenants, including the maintenance of certain leverage ratios and a certain consolidated coverage ratio. The credit agreement also contains various covenants, including affirmative covenants with respect to certain reporting requirements and maintaining certain business activities, and negative covenants that, among other things, may limit or impose restrictions on our ability to incur liens, incur additional indebtedness, make investments, make acquisitions and undertake certain other actions. As of, and during, December 31, 2014 and 2013, we were in compliance with our financial covenants under the credit agreement. There were no outstanding balances on our revolving credit facility at December 31, 2014 and 2013. The weighted average borrowings under the revolving portion of the facility during the years ended December 31, 2014 and 2013 were $9.1 million and $0, respectively. The maximum available borrowing under the revolving credit facility at December 31, 2014 was $499.2 million. At December 31, 2014 and 2013, we were contingently liable under letters of credit totaling $0.8 million and $0.2 million, respectively, which reduces our availability to borrow under our revolving credit facility. 7.25% Senior Unsecured Notes-On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes issued on April 13, 2010 for $200.0 million, which were registered under the Securities Act of 1933. The 7.25% senior unsecured notes were redeemed at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. As a result of the redemption of our 7.25% senior unsecured notes, we recorded a loss on the extinguishment of debt for $10.1 million as non-operating income on our consolidated statement of income during the year ended December 31, 2014. 9. Commitments and Contingencies Contracts with the U.S. government including subcontracts are subject to extensive legal and regulatory requirements and, from time-to-time, agencies of the U.S. government, in the ordinary course of business, investigate whether our operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government investigations of the Company, whether related to our U.S. government contracts or conducted for other reasons, could result in administrative, civil or criminal liabilities, including repayments, fines or penalties being imposed upon the Company, or could lead to suspension or debarment from future U.S. government contracting. Management believes it has adequately reserved for any losses that may be experienced from any investigation of which it is aware. The Defense Contract Audit Agency (DCAA) has completed our incurred cost audits through 2009, with no material adjustments. The remaining audits for 2010 through 2014 are not expected to have a material effect on our financial position, results of operations or cash flow and management believes it has adequately reserved for any losses. In the normal course of business, we are involved in certain governmental and legal proceedings, claims and disputes and have litigation pending under several suits. We believe that the ultimate resolution of these matters will not have a material effect on our financial position, results of operations or cash flows. We lease office space and equipment under long-term operating leases. A number of the leases contain renewal options and escalation clauses. At December 31, 2014, aggregate future minimum rental commitments under these leases are as follows (in thousands): Office Space Equipment Total Year ending: December 31, 2015 December 31, 2016 December 31, 2017 December 31, 2018 December 31, 2019 Thereafter Total $ 29,625 $ 61 $ 25,514 22,942 22,244 21,391 53,515 $ 175,231 $ 7 1 — — — 69 29,686 25,521 22,943 22,244 21,391 53,515 $ 175,300 Office space and equipment rent expense totaled approximately $42.9 million, $47.6 million and $52.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. 60 We had $11.1 million and $11.0 million of deferred rent liabilities resulting from recording rent expense on a straight-line basis over the life of the respective lease for the years ended December 31, 2014 and 2013, respectively. 10. Stockholders' Equity and Stock-Based Compensation Common Stock-We have 150,000,000 shares of authorized Class A common stock, par value $0.01 per share. We have 50,000,000 shares of authorized Class B common stock, par value $0.01 per share. On December 31, 2014, there were 24,179,401 shares of Class A common stock outstanding, 244,113 shares of Class A common stock recorded as treasury stock and 13,192,845 shares of Class B common stock outstanding. Holders of Class A common stock are entitled to one vote for each share held of record and holders of Class B common stock are entitled to ten votes for each share held of record, except with respect to any “going private transaction” (generally, a transaction in which George J. Pedersen (our Chairman of the Board and CEO), his affiliates, his direct and indirect permitted transferees or a group, generally including Mr. Pedersen, such affiliates and permitted transferees, seek to buy all outstanding shares), as to which each share of Class A common stock and Class B common stock are entitled to one vote per share. The Class A common stock and the Class B common stock vote together as a single class on all matters submitted to a vote of stockholders, including the election of directors, except as required by law. Holders of common stock do not have cumulative voting rights in the election of directors. Stockholders are entitled to receive, when and if declared by the Board of Directors from time-to-time, such dividends and other distributions in cash, stock or property from our assets or funds legally and contractually available for such purposes subject to any dividend preferences that may be attributable to preferred stock that may be authorized. Each share of Class A common stock and Class B common stock is equal in respect of dividends and other distributions in cash, stock or property, except that in the case of stock dividends, only shares of Class A common stock will be distributed with respect to the Class A common stock and only shares of Class B common stock will be distributed with respect to Class B common stock. In no event will either Class A common stock or Class B common stock be split, divided or combined unless the other class is proportionately split, divided or combined. The shares of Class A common stock are not convertible into any other series or class of securities. Each share of Class B common stock, however, is freely convertible into one share of Class A common stock at the option of the Class B stockholder. Upon the death or permanent mental incapacity of Mr. Pedersen, all outstanding shares of Class B common stock automatically convert to Class A common stock. Preferred Stock-We are authorized to issue an aggregate of 20,000,000 shares of preferred stock, $0.01 par value per share, the terms and conditions of which are determined by our Board of Directors upon issuance. The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of holders of any shares of preferred stock that we may designate and issue in the future. At December 31, 2014 and 2013, no shares of preferred stock were outstanding and the Board of Directors currently has no plans to issue a series of preferred stock. Accounting for Stock-Based Compensation: Our 2011 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees. Awards granted under the Plan are settled in shares of Class A common stock. At the beginning of each year, the Plan provides that the number of shares available for issuance automatically increases by an amount equal to 1.5% of the total number of shares of Class A and Class B common stock outstanding on December 31st of the previous year. On January 2, 2015, there were 560,584 additional shares made available for issuance under the Plan. Through December 31, 2014, the remaining aggregate number of shares of our common stock authorized for issuance under the Plan was 3,908,967. Through December 31, 2014, there were 4,793,930 shares of our Class A common stock that were issued and remain outstanding as a result of equity awards granted under the Plan. The Plan expires in May 2021. The Plan is administered by the compensation committee of our Board of Directors, along with its delegates. Subject to the express provisions of the Plan, the committee has the Board of Directors' authority to administer and interpret the Plan, including the discretion to determine the exercise price, vesting schedule, contractual life and the number of shares to be issued. Stock Compensation Expense-For the years ended December 31, 2014, 2013 and 2012, we recorded $4.4 million, $5.2 million and $8.1 million of stock-based compensation expense, respectively. No compensation expense of employees with stock awards, including stock-based compensation expense, was capitalized during the periods. For the years ended December 31, 2014, 2013 and 2012, the total recognized tax deficiency from the exercise of stock options, vested cancellations and the vesting of restricted stock were $3.2 million, $2.3 million and $1.4 million, respectively. 61 Stock Options-We typically issue options that vest over three years in equal installments beginning on the first anniversary of the date of grant. Under the terms of the Plan, the contractual life of the option grants may not exceed eight years. During the years ended December 31, 2014 and 2013, we issued options that expire five years from the date of grant. Fair Value Determination-We have used the Black-Scholes-Merton option pricing model to determine fair value of our awards on date of grant. We will reconsider the use of the Black-Scholes-Merton model if additional information becomes available in the future that indicates another model would be more appropriate or if grants issued in future periods have characteristics that cannot be reasonably estimated under this model. The following weighted-average assumptions were used for option grants during the years ended December 31, 2014, 2013 and 2012: Volatility-The expected volatility of the options granted was estimated based upon historical volatility of our share price through weekly observations of our trading history. Expected Term-The expected term of options granted to employees during fiscal years 2014, 2013 and 2012 was determined from historical exercises of the grantee population. For all grants valued during fiscal years 2014, 2013 and 2012, the options have graded vesting over three years in equal installments beginning on the first anniversary of the date of the grant and a contractual term of five years. Risk-free Interest Rate-The yield on zero-coupon U.S. Treasury strips was used to extrapolate a forward-yield curve. This “term structure” of future interest rates was then input into a numeric model to provide the equivalent risk-free rate to be used in the Black-Scholes-Merton model based on the expected term of the underlying grants. Dividend Yield-The Black-Scholes-Merton valuation model requires an expected dividend yield as an input. We have calculated our expected dividend yield based on an expected annual cash dividend of $0.84 per share. The following table summarizes weighted-average assumptions used in our calculations of fair value for the years ended December 31, 2014, 2013 and 2012: Volatility Expected life of options Risk-free interest rate Dividend yield Year Ended December 31, 2014 28.96% 3 years 0.96% 3.00% 2013 31.92% 3 years 0.56% 3.00% 2012 31.68% 3 years 0.48% 2.70% Stock Option Activity-During the year ended December 31, 2014, we granted stock options to purchase 946,576 shares of Class A common stock at a weighted-average exercise price of $29.12 per share, which reflects the fair market value of the shares on the date of grant. The weighted-average fair value of options granted during the years ended December 31, 2014, 2013 and 2012, as determined under the Black-Scholes-Merton valuation model, was $4.76, $4.84 and $5.19, respectively. These options vest over three years in equal annual installments beginning on the first anniversary of the date of the grant and have a contractual term of five years. Option grants that vested during the years ended December 31, 2014, 2013 and 2012 had a combined fair value of $4.4 million, $6.1 million and $8.3 million, respectively. 62 The following table summarizes stock option activity for the years ended December 31, 2014, 2013 and 2012: Stock options at December 31, 2011 Granted Exercised Cancelled and expired Stock options at December 31, 2012 Granted Exercised Cancelled and expired Stock options at December 31, 2013 Granted Exercised Cancelled and expired Stock options at December 31, 2014 Number of Shares Weighted Average Exercise Price Aggregate Intrinsic Value (in thousands) 2,886,110 $ 986,650 $ (38,542) $ (413,022) $ $ 3,421,196 957,525 $ (79,567) $ (899,034) $ $ 3,400,120 946,576 $ (158,371) $ (797,293) $ $ 3,391,032 41.14 29.24 28.93 39.27 38.61 27.42 22.75 39.84 35.51 29.12 24.78 41.75 32.76 $ $ $ $ $ $ $ 1,096 215 626 400 4,488 754 4,722 The following table summarizes non-vested stock options for the year ended December 31, 2014: Non-vested stock options at December 31, 2013 Granted Vested Cancelled Non-vested stock options at December 31, 2014 Number of Shares Weighted Average Fair Value 1,567,945 $ $ 946,576 (711,806) $ (129,187) $ $ 1,673,528 5.51 4.76 6.20 5.07 4.83 The following table includes information concerning stock options exercisable and stock options expected to vest at December 31, 2014: Stock options exercisable Stock options expected to vest Stock options exercisable and expected to vest Weighted Average Remaining Contractual Life (years) Weighted Average Exercise Price Aggregate Intrinsic Value (in thousands) 2.0 4.0 $ $ 36.86 28.54 $ $ 1,634 2,753 Number of Shares 1,717,504 1,475,948 3,193,452 Unrecognized compensation expense related to outstanding stock options expected to vest as of December 31, 2014 was $5.5 million, which is expected to be recognized over a weighted-average period of 2 years and will be adjusted for any future changes in estimated forfeitures. Restricted Stock-Under the Plan, we have issued restricted stock. A restricted stock award is an issuance of shares that cannot be sold or transferred by the recipient until the vesting period lapses. Restricted shares granted to employees vest over three years in equal installments beginning on the first anniversary of the grant date, contingent upon employment with the Company on the 63 vesting dates. Restricted shares granted to our Board of Directors vest in one year. The related compensation expense is recognized over the service period and is based on the grant date fair value of the stock and the number of shares expected to vest. Restricted Stock Activity-The following table summarizes the restricted stock activity during the years ended December 31, 2013 and 2014: Non-vested restricted stock at December 31, 2012 Granted Vested Forfeited Non-vested restricted stock at December 31, 2013 Granted Vested Forfeited Non-vested restricted stock at December 31, 2014 11. Retirement Plans Number of Shares Grant Date Fair Value (in thousands) 27,333 $ 24,000 (30,333) $ — 21,000 21,000 $ (21,000) $ — 21,000 664 825 643 581 As of December 31, 2014, we maintained a qualified defined contribution plan. Our qualified defined contribution plan covers substantially all employees and complies with Section 401 of the Internal Revenue Code. Under this plan, we stipulated a basic matching contribution that matches a portion of the participants' contribution based upon a defined schedule. Additionally, this plan contains a discretionary contribution component where the Company may contribute additional amounts based on a percentage of eligible employees' compensation. Contributions are invested by an independent investment company. The choice of investment alternatives is at the election of each participating employee. Our contributions to the plan were approximately $18.6 million, $19.3 million and $22.6 million for the years ended December 31, 2014, 2013 and 2012, respectively. We maintained an Employee Stock Ownership Plan (ESOP) as of December 31, 2014. On December 18, 1998, the Board of Directors approved the establishment of a qualified ESOP, effective January 1, 1999, for the benefit of substantially all of our U.S. domestic-based employees and some overseas employees. The ESOP is non-leveraged and is funded entirely through Company contributions based on a percentage of eligible employee compensation, as defined in the plan. Participants must be employees of the Company or eligible Company subsidiaries and must meet minimum service requirements to be eligible for annual contributions. The ESOP specifies a five-year vesting schedule over which participants become vested in the Class A common stock allocated to their participant account. The amount of our annual contribution to the ESOP is at the discretion of our Board of Directors. For the years ended December 31, 2014, 2013 and 2012, we recorded $0, $0.9 million and $3.8 million, respectively, as compensation expense related to ESOP contributions. There were no shares, 31,653 shares and 146,589 shares of Class A common stock contributed to the ESOP for the years ended December 31, 2014, 2013 and 2012, respectively. There were no unearned ESOP shares at December 31, 2014 and 2013, respectively. As required under ASC 714-40, Employee Stock Ownership Plans, compensation expense is recorded for shares committed to be released to employees based on the fair market value of those shares in the period in which they are committed to be released. For the years ended December 31, 2013 and 2012, new shares were issued to satisfy this obligation. As of December 31, 2014, we also maintained an Employee Supplemental Savings Plan (ESSP), a non-qualified deferred compensation plan, for certain key employees. Under this plan, eligible employees may defer up to 75% of qualified annual base compensation and 100% of bonus. In the ESSP, participant deferral accounts are credited with a rate of return based on investment elections as selected by the participant. The assets related to the ESSP are held in a rabbi trust owned by the Company for benefit of the participating employees. The trust investments are in the form of variable universal life insurance products, which are owned by the Company. These investments seek to replicate the return of the participant investment elections. Employee contributions to this plan were approximately $3.0 million, $3.2 million and $5.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. We maintained a nonqualified supplemental defined benefit pension plan for certain retired employees of an acquired company as of December 31, 2014. These plans were informally and partially funded beginning in 1999 through a rabbi trust. Assets held in a rabbi trust are not eligible to be included in the calculation of plan status. At both December 31, 2014 and 2013, 100% of the 64 rabbi trust assets were invested in a money market account with a commercial bank. All covered employees retired prior to 1998. Our benefit obligation was $1.3 million at both December 31, 2014 and 2013. 12. Income Taxes The domestic and foreign components of income operations before income taxes and equity method investments were as follows (in thousands): Domestic Foreign Income from operations before income taxes and equity method investments Year Ended December 31, 2014 2013 2012 $ 79,238 (137) $ 6,768 (215) 155,381 (427) 79,101 $ 6,553 $ 154,954 $ $ The provision for income taxes was comprised of the following components (in thousands): Current provision (benefit): Federal State Foreign Deferred provision (benefit): Federal State Year Ended December 31, 2013 2012 2014 $ 10,375 $ 18,702 $ 37,926 2,499 160 13,034 17,739 4,477 22,216 4,011 86 22,799 (6,557) (1,858) (8,415) (2,755) (970) — (3,725) 31,525 $ (2,009) (522) (11) (2,542) 11,842 $ 5,780 123 43,829 15,241 2,332 17,573 (1,306) (161) — (1,467) 59,935 Non-current provision (benefit) resulting from allocating tax benefits directly to additional paid in capital and changes in liabilities: Federal State Foreign Provision for income taxes $ For the year ended December 31, 2014, the non-current benefit for income taxes includes $(3.3) million arising from the cancellation of vested stock options allocated to equity and valuation differences between grant and vesting dates on restricted stock allocated to equity and $(0.4) million related to liabilities for uncertain tax positions. For the year ended December 31, 2013, the non-current benefit for income taxes includes $(2.4) million arising from the cancellation of vested stock options allocated to equity and valuation differences between grant and vesting dates on restricted stock allocated to equity and $(0.1) million related to liabilities for uncertain tax positions. For the year ended December 31, 2012, the non-current benefit for income taxes includes $(1.4) million arising from the cancellation of vested stock options allocated to equity and valuation differences between grant and vesting dates on restricted stock allocated to equity and $(0.1) million related to liabilities for uncertain tax positions (including $(0.1) million for use of a state net operating loss). 65 The schedule of effective income tax rate reconciliation is as follows: Statutory U.S. Federal tax rate Increase (decrease) in tax rate resulting from: State taxes—net of Federal benefit Excess executive compensation Deferred compensation (ESSP) Section 199 deductions Goodwill impairment Tax basis deduction of investment Provisions of American Taxpayer Relief Act of 2012 Acquisition working capital settlement Other, net Effective tax rate Year Ended December 31, 2013 2012 2014 35.0 % 35.0 % 35.0 % 5.0 % 1.3 % (0.7)% (0.6)% — % — % — % — % — % 40.0 % 18.6 % 16.7 % (24.6)% (6.5)% 200.1 % (15.3)% (10.3)% (5.0)% (0.7)% 208.0 % 3.3 % 0.8 % (0.5)% (0.2)% — % — % — % — % 0.3 % 38.7 % The Company paid income taxes, net of refunds, of $14.3 million, $14.9 million and $43.5 million for the years ended December 31, 2014, 2013 and 2012, respectively. Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. A summary of the tax effect of the significant components of deferred income taxes is as follows (in thousands): Gross deferred tax liabilities: Goodwill and other assets Unbilled receivables Property and equipment Total Gross deferred tax assets: Retirement and other liabilities Allowance for potential contract losses and other contract reserves Federal and state operating loss carryforwards Total Net deferred tax liabilities December 31, 2014 2013 $ 86,242 $ 68,940 14,549 3,931 104,722 10,099 5,442 84,481 (31,851) (3,911) (441) (36,203) 68,519 (33,505) (3,687) (829) (38,021) 46,460 $ $ The tax benefits associated with nonqualified stock options and disqualifying dispositions of incentive stock options reduced the current taxes payable by $0.1 million for the year ended December 31, 2014. These benefits were recorded as an increase to additional paid-in capital. At December 31, 2014, we had state net operating losses of approximately $5.2 million that expire beginning 2016 through 2032. 66 A reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits is as follows (in thousands): 2014 December 31, 2013 2012 Gross unrecognized tax benefits at beginning of year $ 1,207 $ 1,376 $ 1,440 Increases in tax positions for prior years Decreases in tax positions for prior years Increases in tax positions for current year Lapse in statute of limitations Gross unrecognized tax benefits at end of year $ 80 (13) 86 (575) 785 $ 95 (26) 69 (307) 1,207 $ 18 — 141 (223) 1,376 The total liability for gross unrecognized tax benefits as of December 31, 2014, 2013 and 2012 includes $0.6 million, $0.9 million and $1.0 million, respectively, of unrecognized net tax benefits which, if ultimately recognized, would reduce our annual effective tax rate in a future period. The Company is subject to income taxes in the U.S., various state and foreign jurisdictions. Tax statutes and regulations within each jurisdiction are subject to interpretation and require significant judgment to apply. The Company is no longer subject to U.S., state or non-U.S. income tax examinations by tax authorities for the years before 2009. The Company believes it is reasonably possible that $0.3 million of gross unrecognized tax benefits will be settled within the next year due to expirations of statute of limitations. The Company recognizes interest related to unrecognized tax benefits within interest expense and penalties related to unrecognized tax benefits in general and administrative expenses. At December 31, 2014, 2013 and 2012, interest and penalties on the net unrecognized tax benefits were $0.2 million, $0.2 million and $0.2 million, respectively. 13. Business Segment and Geographic Area Information We have one reportable segment. We deliver a broad array of information technology and technical services solutions under contracts with the U.S. government. Our U.S. government customers typically exercise independent contracting authority, and even offices or divisions within an agency or department may directly, or through a prime contractor, use our services as a separate customer so long as that customer has independent decision-making and contracting authority within its organization. The U.S. Army Tank-Automotive Armament Command (TACOM) contract accounted for 7.5%, 19.4% and 22.2% of our revenues for the years ended December 31, 2014, 2013 and 2012, respectively. Revenues from the U.S. government under prime contracts and subcontracts were approximately 98.9%, 99.0% and 99.2% of our total revenues for the years ended December 31, 2014, 2013 and 2012, respectively. We treat sales to U.S. government customers as sales within the United States regardless of where the services are performed. U.S. revenues were approximately 99.7%, 99.8% and 99.8% of our total revenues for the years ended December 31, 2014, 2013 and 2012, respectively. International revenues were approximately 0.3%, 0.2% and 0.2% of our total revenues for the years ended December 31, 2014, 2013 and 2012, respectively. Furthermore, substantially all assets from continuing operations were held in the United States for the years ended December 31, 2014, 2013 and 2012. 67 14. Equity Method Investments On May 24, 2012, Fluor-ManTech Logistics Solutions, LLC (FMLS), a limited liability company, was created with Fluor International, Inc. and ManTech as the investees. Each investee has a 50% ownership interest in FMLS. Because we have the ability to exercise significant influence over FMLS we determined that the equity method of accounting will be used for our investment. Under the operating agreement, we are required to provide additional financial support for losses incurred by FMLS. We recorded $456 thousand, $860 thousand and $0 in equity method losses for the years ended December 31, 2014, 2013 and 2012, respectively. We had no investment balance in FMLS as of December 31, 2014 and 2013. As of December 31, 2014 and 2013, we recorded liabilities for $735 thousand and $438 thousand, respectively, which were owed to FMLS for additional financial support. On July 7, 2011, GenTech Partners Joint Venture (GenTech), was created with Genex Systems, LLC and ManTech as the investees. Genex Systems, LLC's interest in GenTech is 51% and ManTech's interest in GenTech is 49%. Because we have the ability to exercise significant influence over GenTech we determined that the equity method of accounting will be used for our investment. We recorded $141 thousand, $0, and $0 in equity method earnings for the years ended December 31, 2014, 2013, and 2012, respectively. Our investment balance in GenTech was $141 thousand and $0 as of December 31, 2014 and 2013, respectively. 15.

Controls and Procedures We performed an assessment as of December 31, 2014 of the effectiveness of the design and operation of our disclosure controls and procedures and our internal control over financial reporting. This assessment was done under the supervision and with the participation of management, including our principal executive officer and principal financial officer. Included as Exhibits 31.1 and 31.2 to this Annual Report on Form 10-K are forms of “Certification” of our principal executive officer (our Chairman of the Board and Chief Executive Officer) and our principal financial officer (our Chief Financial Officer). The forms of Certification are required in accordance with Section 302 of the Sarbanes-Oxley Act of 2002. This section of the Annual Report on Form 10- K that you are currently reading is the information concerning the assessment referred to in the Section 302 certifications and required by the rules and regulations of the SEC. You should read this information in conjunction with the Section 302 certifications for a more complete understanding of the topics presented. Disclosure Controls and Procedures and Internal Control over Financial Reporting-Management is responsible for establishing and maintaining adequate disclosure controls and procedures and internal control over financial reporting. Disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act, such as this Annual Report on Form 10-K, is accurately recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Internal control over financial reporting is a process designed by, or under the supervision of our principal executive officer and our principal financial officer, and effected by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes those policies and procedures that: • • • pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP and that our receipts and expenditures are being made only in accordance with authorizations of management or our Board of Directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material adverse effect on our financial statements. Limitations on the Effectiveness of Controls-Management, including our principal executive officer and our principal financial officer, do not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no assessment of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management's override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. Scope of the Assessments-The assessment by our principal executive officer and our principal financial officer of our disclosure controls and procedures and the assessment by our management of our internal control over financial reporting included a review of procedures and documents and discussions with other employees in our organization in order to evaluate the adequacy of our internal control system design. In the course of the evaluation, we sought to identify exposure to unprevented or undetected data 70 errors, control problems or acts of fraud and to confirm that appropriate corrective action, including process improvements, were being undertaken. The assessment also included testing of properly designed controls to verify their effective performance. Our management used the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission in the Internal Control-Integrated Framework (2013) to assess the effectiveness of our internal control over financial reporting. We assess our disclosure controls and procedures and our internal control over financial reporting on an ongoing basis so that the conclusions concerning controls effectiveness can be reported in our Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K. We consider the results of these assessment activities as we monitor our disclosure controls and procedures and our internal control over financial reporting. Our intent is to ensure that disclosure controls and procedures and internal control over financial reporting will be maintained and updated as conditions warrant. Among other matters, we sought in our assessment to determine whether there were any “material weaknesses” in our internal control over financial reporting, or whether we had identified any acts of fraud involving senior management, management or other personnel who have a significant role in our internal control over financial reporting. This information was important both for the assessment generally and because the Section 302 certifications require that our principal executive officer and our principal financial officer disclose that information, along with any “significant deficiencies,” to the Audit Committee of our Board of Directors, and to our independent auditors and to report on related matters in this section of the Annual Report on Form 10-K. Assessment of Effectiveness of Disclosure Controls and Procedures-Based upon the assessments, our principal executive officer and our principal financial officer have concluded that as of December 31, 2014 our disclosure controls and procedures were effective at the reasonable assurance level described above. Management's Report on Internal Control over Financial Reporting-Management is responsible for establishing and maintaining adequate control over financial reporting. Management used the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission in the Internal Control-Integrated Framework (2013) to assess the effectiveness of our internal control over financial reporting. Based upon the assessments, our management has concluded that as of December 31, 2014 our internal control over financial reporting was effective. Our independent registered public accounting firm issued an attestation report concerning our internal control over financial reporting, which appears further in this Annual Report. Changes in Internal Control over Financial Reporting-During the three months ended December 31, 2014, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control for financial reporting. Item 9B. Other Information None. 71 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders of ManTech International Corporation Fairfax, Virginia We have audited the internal control over financial reporting of ManTech International Corporation and subsidiaries (the "Company") as of December 31, 2014, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company'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, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 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 by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the 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, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2014 of the Company and our report dated February 20, 2015 expressed an unqualified opinion on those financial statements and financial statement schedule. /s/ DELOITTE & TOUCHE LLP McLean, Virginia February 20, 2015 72 Item 10.
