To Our Shareholders

As  we  enter  2013,  ManTech  remains  a  trusted  solutions  provider  for 
national security programs working at the forefront of our customers’ most 
important  missions.  Our  dedicated  employees  make  vital  contributions 
to cyber security, global logistics, defense technology for all branches of 
the DoD, intelligence agencies, NSA, Homeland Security and many other 
agencies of the U.S. government. Our staff  ’s outstanding credentials and 
top security clearances enable ManTech to provide exceptional service to 
our customers around the world. 

The government-services market experienced the slowing of contract awards and 
revenue across the entire industry. ManTech’s revenue declined 10% in 2012, primarily 
the result of reduced requirements for materials and subcontractors. Demand for 
our services remained robust, and we grew our direct staff  during the year.  The 
federal budget also aff ected our mergers and acquisitions strategy during 2012.  
We were cautious in our approach to defense acquisitions and have refocused our 
acquisition strategy on healthcare, commercial cyber, and other non-defense-related 
marketplaces.  With our strong balance sheet and visibility into future cash fl ows, we 
expect to be more acquisitive this year.  

We remain strong. At $2.6 billion in revenue, ManTech is one of the largest providers of 
technology and engineering services to the federal government. Record year-end levels 
of funded backlog, bookings, and cash provide tremendous stability. We are rapidly 
adding staff  to some of our most critical programs. During 2012, we also grew our

working capital and stockholder’s equity. With $135 
million in cash, and an untapped $500 million credit 
revolver, we have the balance sheet and financial 
flexibility to position the business advantageously. We 
currently have $200 million in long-term debt. 

The federal government will continue to require 
substantial support for national and homeland 
security programs, sophisticated intelligence-
gathering and information-sharing activities, and new 
healthcare systems and policies. Even with limited 
growth, the market is immense, and we believe that 
we have significant ability to capture market share 
based on a compelling value proposition. Customers 
are more focused on costs—an opportunity for 
price-competitive providers such as ManTech. To 
position ourselves for future growth, we are focusing 
on execution, competing aggressively for new work, 
building business in growth areas, and allocating 
capital prudently.

Focus on ExEcution

Our customers are increasingly focusing their 
constrained resources on their central missions and 
relying on their most trusted prime contractors. 
ManTech has an enviable position; approximately 90% 
of our work is as a prime contractor, and our people 

often work side by side with customers. We can 
anticipate our customers’ emerging requirements and 
craft solutions to improve their operations.

We understand that quality work and a reputation 
for sterling performance is the best marketing. 
Every year we receive hundreds of letters of 
commendation about the dedication, value, and 
impact of our employees to government missions. 
Our commendations from 2012 include AMBIANCE 
and the FBI’s Criminal Justice Information Services 
(CJIS). First, our AMBIANCE contract is at the heart of 
some of the most compelling technology imperatives, 
including cyber, cloud computing, and data analytics. 
We refresh our customer’s analytical environment 
and help spearhead the Intelligence Community’s 
approach to cloud computing. Second, we provide 
operations and maintenance support to the FBI’s 
CJIS—one of the world’s largest data centers. 
ManTech sustains systems that support millions of 
requests each day, including those used by police to 
check license plates or look for fingerprint matches, 
in the largest biometrics database in the world. Both 
programs grew significantly this year as customers 
moved new tasking to ManTech.

COMPETE AGGRESSIVELY FOR NEW WORK

2012 was a banner year for business development, 
with a record $4.8 billion in contract awards. We were 
awarded the largest contract in our history—a $2.9 
billion contract to provide logistics sustainment and 
support for the Mine-Resistant Ambush-Protected 
(MRAP) Family of Vehicles. This award continues 
our long-standing support of mission-critical work 
that has been instrumental to the protection of the 
nation’s warfi ghters. We are also consolidating work 
under this contract from other companies who 
supported these vehicles. Sustaining the large fl eet 
of vehicles should ensure service work for years to 
come.

In addition to these defi nite contract awards, we won 
prime positions on multiple-award contracts with 
an aggregate potential ceiling value of more than 
$51 billion, including two multi-billion-dollar awards. 
The $7 billion Software and Systems Engineering 
Services—Next Generation contract, enables us to 
pursue higher-end services and solutions work while 
preserving our ability to transition our current eff orts 
to this contract in the future. We also formed a joint 
venture with Fluor Corporation and received a $23 
billion basic ordering agreement to manage logistics 
on an installation basis, covering maintenance, 
supply, and transportation. Both of these contracts 
expand ManTech’s footprint in vital and enduring 
Army programs.

With Government-Wide Acquisition Contracts 
(GWACs) becoming increasingly important, we 
established a GWAC center that will enable us to 
drive business through these contracts from all 
organizations across the company. At the end of 2012, 
we were tracking a pipeline of qualifi ed opportunities 
of approximately $29 billion.  

To strengthen our competitive position, we 
aggressively addressed our cost structure by 
implementing shared services for back-offi  ce 
functions and shrinking leased facilities. We strive to 
effi  ciently manage our operations in order to perform 
our customers’ missions eff ectively. 

BUILD BUSINESS IN GROWTH AREAS

In 2012, we entered two new markets—healthcare 
and commercial cyber—with the acquisitions 
of Evolvent Technologies, Inc., and HBGary. The 
healthcare IT and analytics market allows us to take 
skills that we have gained in our core business—
analyzing, manipulating, and protecting massive 
amounts of data—and apply them to new customers 
and issues. Evolvent’s strong capabilities and 
reputation for innovation in the Military Health 
System provides an excellent foundation. In January 
2013, we augmented our capability in healthcare 
IT with the acquisition of ALTA Systems, Inc., which 
provides entry into the Centers for Medicare and 
Medicaid Services. With these two acquisitions, we 

HBGARY 

HBGary provides enterprise incident 
response solutions and services to enable 
organizations to detect zero-days and other 
unknown malware, validate incidents, 
and respond to incidents. Customers 
include Fortune 50 corporations and U.S. 
government agencies.

attractive assets at reasonable multiples. We have the 
capital and integration experience to take advantage 
of that environment. 

POSITIONED FOR THE FUTURE

Our markets are more challenging than they have 
been in more than a decade, but we believe ManTech 
is well-positioned for that challenge. Our core 
business is comprised of high-priority programs, and 
we have emerging business in growth markets. We 
have seen basic changes in our customers’ missions 
in the past, and we transitioned at those times to 
new and expanding marketplaces. We believe we 
have the technology strength, cash fl ow, and market 
position to grow and adapt to change. We expect that 
our fi nancial means will allow us to thrive in the new 
market due to our cash balance and a $500 million 
line of credit. 

George J. Pedersen
Chairman of the Board and CEO

are now actively pursuing more than $4 billion in 
healthcare opportunities.

Using our acquisition of the HBGary business, we 
are building a complete cyber solutions practice 
that combines products and services and addresses 
commercial and federal markets. HBGary provides a 
comprehensive suite of software products to detect, 
analyze, and diagnose advanced persistent threats 
and targeted malware. This acquisition off ers a natural 
synergy that allows us to off er incident-response 
services to HBGary customers. With the expanded 
team and broader services off ering, we will target 
larger opportunities in new and existing markets. 

ALLOCATE CAPITAL PRUDENTLY

ManTech continues to be a great cash generator, 
delivering $126 million in operating cash fl ow, or 
1.3 times net income, against $15 million in capital 
expenditures. As a result, we can support regular cash 
dividends to shareholders and an acquisition program 
for growth.

Our careful decision to preserve cash in 2012 
strategically positions us for 2013. With a record 
year-end cash balance and a strong balance sheet, 
we expect to be more acquisitive this year, as we 
gain experience in our recent investment areas 
and identify new markets to pursue. We expect the 
market to create outstanding opportunities to gather 

EVOLVENT 

Evolvent transforms healthcare through 
a variety of benefi t management, health 
logistics, health IT, and clinical intelligence 
programs. Our solutions empower patients and 
providers by providing better, richer, and more 
timely data, care coordination solutions, and 
imaging management.

MORE THAN A COMPANY

ManTech is a trusted partner because our business is built on absolute dedication to our customers’ 
missions. This dedication is not just a business model—it is a company value. It has helped us build 
partnerships with customers working throughout the United States and in 19 foreign countries. It 
has inspired us to pursue new areas of business and technology, and it helps us attract and retain 
the best talent available.

In this document, unless the context indicates otherwise, the terms “Company” and “ManTech” as well as the words 
“we”,  “our”,  “ours”  and  “us”  refer  to  both  ManTech  International  Corporation  and  its  consolidated  subsidiaries.    The  term 
“registrant” refers only to ManTech International Corporation, a Delaware corporation.

Industry and market data used throughout this Annual Report on Form 10-K were obtained through surveys and studies 
conducted by third parties, industry and general publications and internal company research.  We have not independently verified 
any of the data from third-party sources nor have we ascertained any underlying economic assumptions relied upon therein.  While 
we are not aware of any misstatements regarding the industry data presented herein, estimates involve risks and uncertainties and 
are subject to change based on various factors, including those discussed in Item 1A “Risk Factors.”

Forward-Looking Statements

This Annual Report on Form 10-K contains forward-looking statements that involve substantial risks and uncertainties, 
many of which are outside of our control.  We believe that these statements are within the definition of the Private Securities 
Litigation Reform Act of 1995.  You can identify these statements by the use of words such as “may”, “will”, “expect”, “intend”, 
“anticipate”, “believe”, “estimate”, “continue”, or the negative of these terms or words of similar import.  You should read statements 
that contain these words carefully because they discuss our future expectations, make projections of our future results of operations 
or financial condition or state other “forward-looking” information.  

Although forward-looking statements in this Annual Report reflect our good faith judgment, such statements can only 
be based on facts and factors currently known by us.  Consequently, forward-looking statements are inherently subject to risks 
and uncertainties and actual results and outcomes may differ materially from the results and outcomes discussed in or anticipated 
by  the  forward-looking  statements.  We  believe  that it  is  important to  communicate our  future  expectations to  our  investors.  
However, there may be events in the future that we are not able to predict accurately or control.  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” 
below, as well as those discussed elsewhere in this Annual Report.  We urge you not to place undue reliance on these forward-
looking statements, which speak only as of the date of this Annual Report.  We undertake no obligation to update any forward-
looking  statement  herein  after  the  date  of  this Annual  Report,  whether  as  a  result  of  new  information,  subsequent  events  or 
circumstances, changes in expectations or otherwise.  We also suggest that you carefully review and consider the various disclosures 
made in this Annual Report that attempt to advise interested parties of the risks and factors that may affect our business, financial 
condition, results of operations and prospects.  

Item 1. 

Business

Business and Corporate 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, Energy and Justice, including the Federal 
Bureau of Investigation (FBI); the healthcare and space communities; and other U.S. federal government customers.  

We support critical national security programs for approximately 50 federal agencies through approximately 1,000 current 
contracts.  ManTech supports major national missions, such as military readiness and wellness, terrorist threat detection, information 
security and border protection.    

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 over the last decade, from 
revenues  of  $0.43  billion  at  the  end  of  2001  to  revenues  of  $2.58  billion  for  the  year  ended  December 31,  2012.   We  have 
approximately 9,700 employees.  For additional financial information, see Item 8 “Financial Statements and Supplemental Data.”

Industry Background

Our primary customer is the U.S. federal government, the largest consumer of services and solutions in the United States.  

In 2012, the U.S. federal government spent about $255 billion on contracted services.  

Our principal focus is on national security and homeland defense customers, the largest of which, the Department of 
Defense (DoD), is the largest purchaser of services and solutions in the federal government.  With a government fiscal year 2012 

3

 
budget of $646 billion, the DoD accounts for approximately 54% of the total discretionary budget and nearly 59% of contracted 
services.  Currently, for government fiscal year 2013, the government is operating under a continuing resolution, which keeps 
spending other than for Overseas Contingency Operations essentially unchanged from 2012 levels, with the potential for reductions 
in the event of sequestration as part of the American Taxpayer Relief Act of 2012.  

After a decade of uninterrupted growth, federal spending has come under pressure given continued budget deficits and 
mounting levels of debt.  In addition, the operations and financial welfare of government contractors are impacted as uncertainty 
about funding levels has led certain customers to delay awards and spending.  The government has also adopted policies adverse 
to our industry.  We expect our customers to continue to be motivated by minimizing costs in this challenging environment, which 
we expect to lower margins across the whole industry.  However, we believe this setting may provide opportunities for price 
competitive providers such as ManTech.  

Moreover, we believe that the federal government's spending will remain robust in key areas for which ManTech is well 
positioned,  including  national  and  homeland  security  programs,  sophisticated  intelligence  gathering  and  information  sharing 
activities required in an increasingly dangerous world and implementation of new healthcare systems and policies.  The U.S. is 
committed to maintaining its superiority in capabilities that we support, such as intelligence, surveillance and reconnaissance 
(ISR),  cyber  security  and  intelligence  analysis  and  operations.   With  an  increasing  veteran  population  and  an  aging  national 
population, investments in healthcare will continue.  The government is actively looking for 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.  Based on these priorities, we believe that ManTech remains well positioned.  

Our Strategy

We believe the Company is well positioned to compete in the current market.  We aspire to be recognized by customers, 
employees, job applicants and investors as the premier provider of technology and engineering services and solutions to the federal 
government market.  We are executing a multi-year strategy for achieving this objective, which is comprised of the following:

• 

Provide Direct Support to Our Customers' Most Critical Missions

When resources are constrained, we believe that our customers will increasingly focus on mission and rely on their most 
trusted prime contractors.  Since our founding in 1968, we have focused on providing technology-based solutions and services 
for mission-critical national security programs.  Most of our work centers around our customers' core mission as opposed to support 
functions.  We have several long standing customer relationships; many of our early customers are still our customers today.  
Because our personnel are on-site with, or 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.

The prime contractor position is increasingly important, and we have aggressively pursued new prime positions both 
organically and through acquisitions.  In fiscal year 2012, we derived 89.9% of our revenues as a prime contractor, compared to 
85.6% and 75.9% in fiscal years 2011 and 2010, respectively.  As a prime contractor, we are able to enhance the relationship with 
our customers, ensure overall program success, foresee emerging requirements and manage project resources.

• 

Compete Aggressively on New Opportunities

We  closely  track  our  customers'  requirements  and  funding  and  have  built  our  capability  and  capacity  to  pursue  the 
opportunities that arise.  We intend to capitalize on our global footprint and long-term relationships with our customers and our 
reputation within the intelligence community, DoD and other government agencies to attract new customers and to cross-sell our 
broad array of solutions to our existing customers.  Our successful track record and technical expertise give us credibility with 
our current customers and enhance our ability to gain follow-on contracts and compete for new programs.  In 2012, we won a 
record $4.8 billion in new business awards, and we finished the year with a pipeline of qualified opportunities of $28.8 billion.  

• 

Build Presence in New Growth Markets

We believe the projected growth in government technical services spending will offer opportunities for development and 
delivery of advanced technology solutions for enterprise applications and information systems.  We intend to expand our service 
offerings in such high growth program areas.  In particular, we intend to focus on providing new or improved solutions in cyber 
security, information assurance and command, control, communications, computers, intelligence, surveillance and reconnaissance 
(C4ISR) solutions and services, and health IT, and we have established plans around the potential growth area of border security. 

4

 
We plan to pursue strategic acquisitions of businesses that can broaden our domain expertise and service offerings and 
allow us to establish relationships with new customers.  We have successfully acquired 21 businesses since our IPO in February 
2002.  Since December 31, 2011, we completed the following acquisitions:

•  ALTA Systems, Inc. (ALTA) - On January 8, 2013, we acquired ALTA, a provider of IT and professional services 
with valuable applications in healthcare systems and capital planning.  The acquisition will enable ManTech to 
deliver technology services through ALTA's prime position on the Centers for Medicare and Medicaid Services 
(CMS) Enterprise Systems Development (ESD) contract, an Indefinite Delivery/Indefinite Quantity (ID/IQ) 
contract vehicle with a $4 billion ceiling and period of performance through May 2018. 

HBGary, Inc. (HBGary) - On April 2, 2012, we acquired the business of HBGary, a provider of software products 
to detect, analyze and diagnose Advance Persistent Threat and targeted malware to customers for their cyber 
security needs in the financial services, energy, critical infrastructure and technology sectors. 

Evolvent Technologies, Inc. (Evolvent) - On January 6, 2012, we acquired Evolvent, a provider of services in 
clinical  IT,  clinical  business  intelligence,  imaging  cyber  security,  behavioral  health,  tele-health,  software 
development  and  systems  integration  to  the  DoD  health  organizations,  the Veterans Administration  and  the 
Department of Health and Human Services. 

We will continue to seek out new growth areas.  Our balance sheet and $500.0 million revolving credit facility provide 

us with ample capacity to expand our business through strategic acquisitions. 

• 

Focus on Shareholder Returns

During fiscal year 2012, we generated $126.3 million in operating cash flow and paid $31.0 million in dividends to our 
shareholders.  We believe that ManTech is a compelling investment due to our regular cash dividend program and our strong 
competitive positioning.

We combine deep domain understanding and technical capability to deliver comprehensive IT, systems engineering, 
technical and other services and solutions, primarily in support of mission critical national security programs for the intelligence 
community; DoD; and healthcare and space communities, including the National Aeronautic and Space Administration (NASA).  
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 that we provide are aligned with the long-term needs of our customers: C4ISR solutions and services; 
cyber security; global logistics support; IT modernization and sustainment intelligence/counter-intelligence solutions and support; 
systems engineering; test and evaluation; environmental, range and sustainability services; and healthcare analytics and IT.  

C4ISR Solutions and Services

Military operations increasingly rely on communication and information architectures that offer global connectivity and 
interoperability between joint, interagency and multi-national forces.  We provide the full-spectrum of C4ISR solutions and services 
in support of national defense, intelligence and homeland security missions.  Our C4ISR solutions and services include systems 
engineering, systems integration and software engineering using the latest Agile methodologies.  Our end-to-end lifecycle services 
enable our customers to accomplish critical, complex missions using the latest in technology.  We integrate systems, sensors, multi-
source intelligence information, data dissemination systems and applications to ensure the troops have the right information at the 
right time on the battlefield.  Our support spans the entire lifecycle continuum, from initial requirements assessment and  program 
management  support,  through  engineering,  development  and  integration,  test  and  evaluation,  deployment  and  training  to  the 
ultimate operation and maintenance of C4ISR solutions.  Our experience spans all of the military services, with support provided 
in the U.S. and in deployed locations worldwide.  We are also engaged at Fort Bliss, TX in support of the Army's Network Integration 
Evaluation exercises and provide network engineering and other technical support to the C4ISR lifecycle.

Through various roles from program management and acquisition support to software development and integration, we 
have supported the delivery of C4ISR-related solutions for the U.S. Army Communications-Electronics Command (CECOM), 
the  U.S.  Navy  Space  &  Naval  Warfare  Systems  Command  (SPAWAR)  and  the  U.S.  Marine  Corps  Systems  Command 
(MARCORSYSCOM).  Our experience in delivering new capabilities includes many critical systems such as the Joint Network 
Node (JNN), the Distributed Common Ground Systems-Army (DCGS-A), the Advanced Monitoring Display System (AMDS), 
the EQ-36 RADAR system and many others.  ManTech has a proven record in successful post-development support for C4ISR 

5

 
 
systems.  For major systems like the Army's DCGS-A and Base Expeditionary Targeting and Surveillance Systems-Combined 
(BETSS-C), we provide training, fielding, logistics support and forward maintenance.  

Cyber Security

Ubiquitous  security  challenges  threaten  not  just  traditional  IT,  but  also  C4ISR  and  other  national  security  systems; 
embedded electronics on ground, sea and aerospace platforms; classified and law enforcement networks & systems; health IT; 
and systems providing critical civilian services. Our team of security experts tackles some of 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 security operations centers (SOCs), 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, NASA and other federal agencies.  We operate 24/7 
SOCs for several key government customers, including the departments of Justice and Agriculture and the FBI.

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 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 developed 
and staff a national level computer forensic laboratory and provide a broad spectrum of subject matter expertise, including reverse 
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.  

Global Logistics Support

In recent years the DoD, Department of State and other federal agencies have experienced an increased need for logistics 
support worldwide.  For decades, ManTech has provided a wide range of core services to meet such needs, including supply chain 
management support (such as warehousing, logistics management, shipping/receiving and property management), maintenance 
and reset of ground vehicles and electronics, transportation using contracted and government provided services and other field 
services support (including fielding, training and operations support).

We provide logistics, repair and maintenance services, unique system training and development curriculum support, 
resource management and inventory tracking technologies for complex, critical and specialized customer systems in deployed, 
isolated and remote locations worldwide.  On behalf of the U.S. Army in Southwest Asia, we maintain critical and life-sustaining 
operational  readiness  levels  for  counter-improvised  explosive  device  (IED)  vehicles  and  systems,  including  Mine-Resistant 
Ambush-Protected (MRAP) vehicles and MRAP All-Terrain Vehicles (M-ATV).  To that end, we develop and manage supply 
levels  and  the  streamlined  operation  of  supply-chain  channels,  including  vendor  partnerships  with  original  equipment 
manufacturers to ensure the expedient, unencumbered delivery of systems and parts to forward operating theater locations. 

We also support the U.S. Department of State Global IT Modernization Program by centrally managing the worldwide 
modernization of their computer networks.  We design, support the procurement of and integrate the latest system software and 
hardware technologies including servers, switches, workstations and network printers.  Our installation teams travel to Department 
of State locations worldwide to complete each installation.

IT Modernization and Sustainment

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 design, develop, deploy, modernize, operate and maintain IT systems 
and infrastructure as a stand-alone service offering to improve mission performance and lower costs for our government customers. 
For the Department of State, we modernize classified and unclassified networks and systems in locations around the world.  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.  For the Defense 
Commissary Agency, we provided Network Operations Center services to sustain its global network infrastructure and manage 
hardware and software at remote sites from headquarters.

We  leverage  our  strong  engineering  discipline  to  aid  our  customers  in  moving  their  IT  enterprise  infrastructure  and 
applications from disparate instances into cloud 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  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 24x7; we 
understand that the 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. 

Intelligence/Counter-Intelligence Solutions and Support

We provide robust information technology solutions and mission support services that the national intelligence agencies 
and other classified program customers need to assure continuous operations, improve data gathering and analysis, collaborate 
securely and protect program security. 

The ability to collaborate and share information across non-traditional boundaries in a trusted fashion has become critically 
important for national security.  For example, we developed A-Space, a next-generation analytic sharing and collaboration program 
used  by  intelligence  analysts,  and  the  DoD  Intelligence  Information  Systems  (DoDIIS)  service-oriented  architecture  (SOA) 
framework, which helps intelligence analysts comb through millions of intelligence reports to find relevant and meaningful answers 
to national security questions. 

Our network architecture planning and implementation services and systems engineering services support enterprise-
wide  network  infrastructures  and  components  that  include  local  area  network/wide  area  network  architectures,  messaging 
architectures, network management solutions, directory services architecture and web hosting.  These services are provided within 
secure environments requiring the application of multi-level security policies across the enterprise.  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.

We support strategic and tactical intelligence systems, networks and facilities across the intelligence community and 
DoD.  We develop and integrate collection and analysis systems and techniques.  We also provide support to the development and 
application  of  analytical  techniques  to  counterintelligence,  Human-Intelligence  operations/training  and  counter-terrorist 
operations.  For example, we support intelligence operations designed to counter narcotics trafficking along our nation's southwest 
border.

Highly-classified programs, including intelligence operations and military programs, require secrecy management and 
security  infrastructure  services.   These  services  can  include  vulnerability  assessment,  exposure  analysis,  secrecy  architecture 
design, security policy development and implementation, lifecycle acquisition program security, operations security, information 
7

 
 
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.  

Systems Engineering 

Since 1968, ManTech's scientists and engineers have provided disciplined systems engineering support to a wide range 
of customers that presently includes programs and offices within the Department of Homeland Security (DHS), DoD, intelligence 
community and NASA. 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.  

Moreover, because ManTech is not a major system developer, we provide systems engineering advisory services to our 
government customers without concerns about potential conflicts of interest. In fact, ManTech was one of the first companies to 
have sought and received certification as a “non-conflicted” services provider from the National Reconnaissance Office.

Test and Evaluation

ManTech is a leading provider of test and evaluation services to a wide range of defense, intelligence, homeland security 
and space customers.  Our test and evaluation 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 Independent Validation & Verification (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.  

We test complex and mission-critical hardware and software systems used by the Army, Navy, Marine Corps and NASA, 
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 associated test and evaluation required 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, for the past 24 years ManTech has installed, operated and maintained a large 
and complex joint test environment for the Joint Interoperability Test Command within DISA.  Recently, we built a systems 
integration lab (SIL) for a DoD customer that enables engineers to test new hardware and software on a virtual copy of the enterprise 
architecture.  Once per quarter, virtual snapshots are taken of the servers and placed in the SIL to create an accurate facsimile of 
the production environment.  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.  
ManTech provides support testing for command, control, communications, computers and intelligence, navigation and sensor 
systems for reliability, availability and maintainability, electromagnetic interference/electromagnetic compatibility and security. 
We provide a full spectrum of services including scientific, engineering, technical, administrative, maintenance and logistics. 
8

Other services include instrumentation and hardware/software-related development, as well as laboratory/test bed operations and 
special studies in Aberdeen Proving Ground, MD; Fort Huachuca; Yuma Proving Ground, AZ; Fort Hood and Fort Bliss, TX; Fort 
Lewis, WA; and White Sands Missile Range, NM.

Environmental, Range and Sustainability Services

ManTech is a leader in the fields of range, environmental 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.

Also, ManTech has supported Vandenberg Air Force Base to execute its environmental planning programs for nearly 25 
years.  ManTech has a diverse background in all aspects of launch-support operations and environmental planning for the 30th 
Civil Engineering Squadron Environmental Flight.  We understand both the unique operational conditions and mission requirements 
of this installation and its tenant commands and the demands of sustaining and conserving the natural and cultural resources that 
are found at Vandenberg Air Force Base.  Our support includes a team of highly experienced biologists, ecologists and National 
Environmental Policy Act (NEPA) specialists.  ManTech's support under this program includes sensitive species management 
plans, threatened and endangered species surveys, marine mammal monitoring, invasive species control, construction monitoring, 
habitat restoration plans and implementation, predator control, biological and environmental assessments, mitigation monitoring, 
erosion control, storm water monitoring and solid waste environmental compliance. 

Healthcare Analytics and IT

As a focused healthcare systems integrator with particular strength in federal healthcare systems, ManTech supports a 
wide range of programs that enable clinical intelligence, quality, patient and family centric care, chronic disease management, and 
comparative effectiveness research.  We deliver domain-specific capabilities, including solutions that encompass health information 
sharing and clinical analytic solutions.  Our technology solutions empower patients and providers with better, richer, and more 
timely data, care coordination solutions, and imaging management capabilities-all built on interoperable platforms to new national 
standards.    For  imaging,  informatics,  interoperability  and  integration  challenges,  our  team  provides  a  powerful  ally  in  the 
transformation of health IT.

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).  The legacy BHIE system was so successful that demands placed on 
the system outgrew its original design.  ManTech helped migrate the 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.  VLER relies on the Nationwide Health 
Information Network as the mechanism through which to share standards-based health data between DoD, VA and private sector 
partners.  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.

Our Customers

Our primary customers are U.S. federal 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 40 years.

Our customers include the departments of Defense, State, Homeland Security, Energy and Justice, including the FBI; the 

healthcare and space communities and other U.S. federal 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 federal 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 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 22.2%, 17.0% and 12.2% of our revenues for the years ended December 31, 2012, 2011 and 2010, respectively.  In 
addition, there were no sales to any customers within a single country (except for the United States) where such sales accounted 
for 10% or more of our total revenues.

Foreign Operations

We treat sales to U.S. government customers as sales within the United States, regardless of where services are performed.  
North Atlantic Treaty Organization is the Company's largest international customer.  The percentages of total revenues by geographic 
customer for the last three years were as follows:

At December 31, 2012, our backlog was $6.5 billion, of which $1.8 billion was funded backlog.  At December 31, 2011, 
our backlog was $4.7 billion, of which $1.3 billion was funded backlog.  Backlog represents estimates that we calculate on the 
basis described below.  We expect that approximately 37% of our total backlog will be recognized as revenues prior to December 
31, 2013.

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 indefinite delivery/indefinite quantity (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.

10

 
 
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 canceled, a contract could be modified or canceled, 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, we do not consider our business to be dependent on the existence or protection of such intellectual 
property.

Seasonality

Our business is not seasonal. However, it is not uncommon for federal government agencies to award extra tasks or 
complete other contract actions in the weeks before the end of the federal 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. 

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 team members in other situations.  Major differentiators for ManTech in our markets include our 
distinctive technical competencies, extensive experience supporting mission-critical national security programs, successful past 
contract performance, reputation for quality at a competitive price and key management with domain expertise.

Risk Factors 

Forward-Looking and Cautionary Statements

Set forth below are the risks that we believe are material to investors who purchase our common stock. 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. federal government for substantially all of our revenues.  If our relationships with the 
federal government were harmed, our business, future revenues and growth prospects could be adversely affected. 

We derive the vast majority of our revenues from our federal government customers.  We expect that federal 
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 federal 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. 

12

 
Among  the  key  factors  in  maintaining  our  relationships  with  federal  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. 

Federal 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 federal government expenditures on intelligence, defense and other programs that 
we support.  These expenditures have not remained constant over time.  Today, in the face of growing national debt, and long-
term fiscal challenges facing the nation, spending levels for federal government programs generally, and in particular the U.S. 
defense budget, have come under pressure.  We expect that the focus on minimizing costs will continue for the foreseeable future.  
This  focus  may  affect  future  levels  or  timing  of  expenditures,  place  pressure  on  operating  margins  in  our  industry,  and  shift 
authorizations to programs in areas where we do not currently provide services, thereby adversely impacting our future results of 
operations.  The possibility that automatic spending reductions mandated by the American Tax Payer Relief Act of 2012 may still 
be triggered and uncertainty about how these automatic reductions may be applied, heightens the risk that spending levels for 
programs we support will change in a manner that is adverse to us.  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.

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 federal government's fiscal year on September 
30, Congress typically funds government operations pursuant to a continuing resolution.  A continuing resolution allows federal 
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 canceled.  The federal government's failure to complete its 
budget process, or to fund government operations pursuant to a continuing resolution, may result in a federal government shutdown, 
such as that which occurred during the 1996 fiscal year.

The competitive bidding process can impose substantial constraints and costs upon us and we may lose revenues, or our earnings 
and profitability may be adversely impacted, if we fail to compete effectively, if we are required to minimize our price in order 
to compete effectively, or if there are delays caused by protests or challenges of contract awards.  

We derive significant revenues from federal government contracts that are awarded through a competitive bidding process.  
We expect that a significant portion of our future business will also be awarded through competitive bidding. Competitive bidding 
presents a number of risks, including: 

• 

Incurring expense and delays due to competitor's protest or challenge of contract awards made to us, 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;

•  Bidding on programs in advance of the completion of their design, this may result in unforeseen difficulties in 

execution, cost overruns, or, in the case of unsuccessful competition, the loss of committed costs;

• 

• 

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;

Failing to accurately estimate the resources and cost structure that will be required to service any contract we 
are awarded;

•  Changes to customer bidding practices or government reform of its procurement practices, which may alter the 

prescribed contract requirements relating to contract vehicles, contract types and consolidations; and

•  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.

13

Additionally, the current federal government budget environment has led an increasing number of our customers to focus 
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 federal government contracts.  Continuation of the constrained 
budgetary environment for our customers may lead to additional pricing pressures, which may require us to further minimize our 
price in order for us to successfully bid for contracts, thereby adversely affecting our earnings and profitability.

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.  Even if we win a particular contract through competitive bidding, our profit margins 
may be depressed as a result of the costs incurred through the procurement process.  Additionally, the competitive bidding process, 
and increased use by the federal 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. 

Our earnings and profitability may vary based on the mix of type of contracts we perform and 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 federal government contracts for our services: cost-reimbursable, time-and-materials and 
fixed-price.  Recently, 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

Time-and-materials

Fixed-price

Total Revenues

Year Ended December 31,

2012

2011

50.5%

15.9%

100.0%

20.9%

63.7%

15.4%

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  federal  government  on  the  extent  to  which  contractors  are  able  to  receive 
reimbursement for employee compensation.  

•  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.

•  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 federal 
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.

Our profits could be adversely affected if our costs under any of these contracts exceed the assumptions we used in 

bidding for the contract.  

14

Many of our federal 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. federal 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.  

Federal 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. 

Federal 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 federal 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. 

We may not receive the full amount authorized under our contracts and we may not accurately estimate our backlog, which 
could adversely affect our future revenues and growth prospects. 

As of December 31, 2012, our estimated contract backlog totaled approximately $6.5 billion, of which approximately 
$1.8 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, we cannot assure that all, or any, of such estimated contract revenues will be recognized as revenues.  

15

We historically have not realized all of the revenue included in our total backlog, and we may not realize all of the revenue 
included in our total backlog in the future.  There is a somewhat higher degree of risk in this regard with respect to unfunded 
backlog, since it contains management's estimate of amounts expected to be realized on unfunded contract work that may never 
be realized as revenues.  In addition, there can be no assurance that our backlog will result in actual revenue in any particular 
period, or at all, because the actual receipt, timing, and amount of revenue under contracts included in backlog are subject to 
numerous uncertainties, including congressional appropriations, many of which are beyond our control.  In particular, delays in 
the completion of the U.S. government's budgeting process and the use of continuing resolutions could adversely affect our ability 
to timely recognize revenue under our contracts included in backlog.  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 
canceled; 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 federal government spending.  If we fail to 
realize as revenues those amounts included in our backlog, our future revenues and growth prospects may be adversely affected.  

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.  We compete 
with larger companies that have greater name recognition, financial resources and larger technical staffs.  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 federal 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.

Failure to maintain strong relationships with other contractors could result in a decline in our revenues. 

For the years ended December 31, 2012 and 2011, we derived 10.1% and 14.4% of our revenues, respectively, from 
contracts in which we acted as a subcontractor to other contractors.  Additionally, where we are named as a prime contractor, we 
may sometimes enlist other companies to perform some services under the contract as subcontractors.  We expect to continue to 
depend on such relationships with other contractors for a portion of our revenues for the foreseeable future.  Our business, prospects, 
financial condition or operating results could be harmed if other contractors eliminate or reduce their contracts or joint venture 
relationships with us because they choose to establish relationships with our competitors; they choose to directly offer services 
that compete with our business; we choose to directly compete with them for services; the government terminates or reduces these 
other contractors' programs; or the government does not award them new contracts.  

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.  We have made a number of acquisitions in the 
past and we expect that a portion of our future revenues will continue to come from such transactions.  We evaluate potential 
acquisitions on an ongoing basis.  Our acquisitions strategy poses many risks, including:

•  We may not be able to identify suitable acquisition candidates at prices we consider attractive;

•  We may not be able to compete successfully for identified acquisition candidates, complete future acquisitions 

or accurately estimate the financial effect of acquisitions on our business;

• 

Future acquisitions may require us to issue common stock or spend significant cash, resulting in dilution of 
ownership or additional leverage;

•  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;

•  Acquisitions may disrupt our business or distract our management from other responsibilities; and

16

•  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.

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.

We have substantial investments in recorded goodwill and changes in future business conditions could cause these investments 
to become impaired, requiring substantial write-downs that would reduce our operating income and impact our financial 
position.

As of December 31, 2012, our goodwill was $861.9 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.    During  the  second  quarter,  we  completed  our  annual  goodwill 
impairment test and no impairment losses were identified.  However, 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, events outside of our control, such as deteriorating market conditions for companies in our industry, may indicate a 
potential impairment.  If there is an impairment, we would be required to write down the recorded amount of goodwill, which 
would be reflected as a charge against operating income.  

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  federal 
government contracts.  These laws and regulations affect how we conduct business with our federal 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 federal 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 federal 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 federal 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: 

•  Termination of contracts; 

• 

Forfeiture of profits;

•  Cost associated with triggering of price reduction clauses;

• 

Suspension of payments;

17

• 

• 

Fines; and

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. 

The federal government may change its procurement or other practices in a manner adverse to us.

The federal government may change its procurement practices or adopt new contracting laws, rules or regulations, such 
as cost accounting standards.  For example, it could change its preference for procurement methods and/or contract type in a 
manner that is unfavorable to contractors in our industry generally.  Any such change could potentially place greater pressure on 
our profit margins, and could materially harm our operating results.  Additionally, aspects of the federal government's procurement 
system, such as the number of acquisition personnel available to support the workload imposed by an increasing number of protests, 
could exacerbate delays in the procurement decision making process, thus delaying our ability to generate revenues from proposals 
and  awards.   The  federal  government  could  also  adopt  new  socio-economic  requirements,  which  could  reduce  our  revenues 
opportunities.  Any new contracting methods could be costly or administratively difficult for us to satisfy and, as a result, could 
cause actual results to differ materially and adversely from those anticipated.  

Unfavorable federal 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.  Recently, U.S. government contractors, including our Company, have seen a trend of 
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 
federal  government  contracts  that  we  support.   The  DCAA  has  also  generally  increased  its  examination  of  U.S.  government 
contractors that, like our Company, perform services outside the United States, particularly in Southwest Asia.  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.  DCAA has completed our incurred cost audits through 2002 and the majority of the audits for 2003, 2004 and 2005, 
with no material adjustments.  While we believe that the vast majority of incurred costs will be approved upon final audit, we do 
not know the outcome of any future audits and adjustments and, if any future audit adjustments exceed our estimates, our profitability 
could be adversely affected. 

U.S. government contractors are subject to a greater risk of investigation, criminal prosecution, civil fraud, whistleblower 
lawsuits  and  other  legal  actions  and  liabilities  than  companies  with  solely  commercial  customers.    In  addition  to  increased 
investigation by the DCAA, contractors that provide support services to U.S. forces in Southwest Asia have also come under 
increasing scrutiny by agency inspectors general, other government auditors and congressional committees.  If a government audit 
or other investigation uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative 
sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or debarment 
from doing business with federal government agencies.  More generally, increased scrutiny and investigation into business practices 
and into major programs supported by contractors may lead to increased legal costs and may harm our reputation and profitability 
if we are among the targeted companies, regardless of the underlying merit of the allegations being investigated.

18

Covenants in the instruments governing our indebtedness 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 $500.0 million revolving credit facility.  The maturity date for the credit agreement is October 12, 
2016.  The terms of the credit agreement permit prepayment and termination 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 
total leverage ratios and a certain fixed charge 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 restriction on ability to incur liens, incur additional indebtedness, make 
investments, make acquisitions and undertake certain other actions.

We have $200.0 million in aggregate principal amount of 7.25% senior unsecured notes due April 15, 2018.  These 7.25% 
senior unsecured notes were issued at 100% of the aggregate principal amount and are effectively subordinate to the Company's 
existing and future senior secured debt (to the extent of the value of the assets securing such debt), including any debt outstanding 
under our revolving credit facility.  The indenture governing these notes contains customary events of default, as well as restrictive 
covenants, which, subject to important exceptions and qualifications specified in the indenture, will, among other things, limit our 
ability and the ability of our subsidiaries that guarantee the 7.25% senior unsecured notes to: pay dividends and distributions; 
repurchase equity; prepay subordinated debt or make certain investments; incur additional debt or issue certain disqualified stock 
and preferred stock; incur liens on assets; merge or consolidate with another company or sell all or substantially all assets; and 
allow to exist certain control provisions.  

As a result of such covenants and restrictions in the instruments governing our indebtedness, we will be limited in how 
we conduct our business and we may be unable to raise additional debt or equity financing to take advantage of new business 
opportunities.  In addition, our ability to satisfy the financial ratios required by our instruments of indebtedness can be affected 
by events beyond our control and we cannot assure you that we will meet these ratios.  We cannot assure you that we will be able 
to maintain compliance with these covenants in the future and, if we fail to do so, we may be in default under our revolving credit 
facility or the indenture, and we may be prohibited from undertaking actions that are necessary or desirable to maintain and expand 
our business. 

Default under our revolving credit facility could allow the lenders to declare all amounts outstanding to be immediately 
due and payable.  We have pledged substantially all of our assets to secure the debt under our revolving credit facility.  If the 
lenders declare amounts outstanding under the revolving credit facility to be due, the lenders could proceed against those assets.  
Any event of default, therefore, could have a material adverse effect on our business if the creditors determine to exercise their 
rights. 

Default under the indenture governing our 7.25% senior unsecured notes will allow either the trustee or the holders of at 
least  25%  in  principal  amount  of  the  then  outstanding  7.25%  senior  unsecured  notes  to  accelerate,  or  in  certain  cases,  will 
automatically cause the acceleration of, the amounts due under the 7.25% senior unsecured notes.  Any event of default, therefore, 
could have a material adverse effect on our business if the amounts due are accelerated. 

Our level of indebtedness could materially adversely affect our ability to generate sufficient cash to fulfill our obligations 
under our outstanding indebtedness, our ability to react to changes in our business and our ability to incur additional 
indebtedness to fund future needs.

Our level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay, when due, 

the principal of, interest on or other amounts due in respect of our indebtedness.  Our indebtedness, combined with our other 
financial obligations and contractual commitments, could: 

•  make it more difficult for us to satisfy our obligations with respect to our indebtedness, including our 7.25% 
senior unsecured notes and indebtedness under our credit agreement, and any failure to comply with the 
obligations under any of our debt instruments, including restrictive covenants, could result in an event of 
default under the indenture governing the notes, our revolving credit facility or any agreements governing 
other indebtedness;

• 

require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, 
thereby reducing funds available for working capital, capital expenditures, acquisitions, research and 
development and other corporate purposes;

19

• 

• 

• 

• 

• 

increase our vulnerability to adverse economic and industry conditions, which could place us at a competitive 
disadvantage compared to competitors that have relatively less indebtedness;

limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we 
operate;

limit the rights of the holders of our 7.25% senior unsecured notes to receive payments under the notes if 
secured creditors have not been paid; 

limit our ability to borrow additional funds, or to dispose of assets to raise funds, if needed, for working 
capital, capital expenditures, acquisitions, research and development and other corporate purposes; and 

prevent us from raising the funds necessary to repurchase all of our 7.25% senior unsecured notes tendered to 
us upon the occurrence of certain changes of control, which would constitute a default under the indenture 
governing the notes.

Subject to the restrictions in our revolving credit facility and the indenture governing our senior notes, we may incur 
significant additional indebtedness.  If we incur a substantial amount of additional indebtedness, the related risks that we face 
could become more significant.  Additionally, the terms of any future debt that we may incur may impose requirements or restrictions 
that further affect our financial and operating flexibility or subject us to other events of default.

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. 

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 federal 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. 

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 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 
20

 
 
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.  

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.

If our subcontractors or joint venture partners fail to perform their contractual obligations, our performance and reputation 
as a prime contractor and our ability to obtain future business could suffer. 

As a prime contractor, we often rely significantly upon other companies as subcontractors to perform work we are obligated 
to perform for our customers.  If one or more of our subcontractors fail to perform satisfactorily the agreed-upon services on a 
timely basis, or violate government contracting policies, laws or regulations, our ability to perform our obligations or meet our 
customers' expectations as a prime contractor may be compromised.  In some cases, we have limited involvement in the work 
performed by the subcontractors but are nevertheless responsible for such work.  In extreme cases, performance or other deficiencies 
on the part of our subcontractors could result in a customer terminating our contract for default.  A termination for default could 
expose us to a liability for the agency's costs of reprocurement, damage our reputation and hurt our ability to compete for future 
contracts and task orders. 

Additionally, we often 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.

21

 
 
 
 
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.

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 federal 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: federal 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 federal 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.   

Our business depends upon obtaining and maintaining required security clearances. 

Many of our federal 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. 

22

 
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.

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  federal  government  officials  that  affect  the  timing  of 

technology procurement;

•  Changes in federal 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 

23

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, and we anticipate paying quarterly dividends 
for 2013 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, 2012, Mr. Pedersen owned approximately 36% 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, 
2012, thus he controlled approximately 85% of the combined voting power of our stock as of December 31, 2012.  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. 

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, 2012, we leased 
25 facilities throughout the metropolitan Washington, D.C. area and 47 facilities in other parts of the United States, for approximately 
1,476,000 square feet.  We also have employees working at customer sites throughout the United States and in other countries.  
Our leases expire between 2013 through 2024. 

24

 
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 federal 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 federal 
government or a particular agency or civil or criminal proceedings seeking penalties and/or fines.  Audits and investigations 
conducted by the federal 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.

There is no established public market for our Class B common stock. 

As of February 20, 2013, there were 59 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 year 2012, we declared and paid quarterly dividends, each in the amount of $0.21 per share, on all issued 
and outstanding shares of common stock.  During the year ended December 31, 2011, we declared and paid semi-annual  dividends, 
each in the amount of $0.42 per share on all issued and outstanding shares of common stock.  For 2013, we anticipate paying 
quarterly dividends, each in the amount of $0.21 per share.  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. 

Recent Sales of Unregistered Securities 

We did not issue or sell any securities in fiscal year 2012 that were not registered under the Securities Act of 1933.  The 

issuance of shares to the Employee Stock Ownership Plan did not constitute sales within the meaning of the Securities Act.

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, 2012.

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; departments of Defense, State, Homeland Security, Energy and Justice, including the Federal 
Bureau of Investigation (FBI); healthcare and space communities; and other U.S. federal government customers.  We provide 
support to critical national security programs for approximately 50 federal agencies through approximately 1,000 contracts.  Our 
services  include  the  following  solution  sets  that  are  aligned  with  the  long-term  needs  of  our  customers:  command,  control, 
communications, computers, intelligence, surveillance and reconnaissance (C4ISR) solutions and services; cyber security; global 
logistics support; IT modernization and sustainment; intelligence/counter-intelligence solutions and support; systems engineering; 
test and evaluation; environmental, range and sustainability services; and healthcare analytics and IT.  ManTech supports 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.

We derive revenues primarily from contracts with U.S. government agencies that are focused on national security and as 
a result, funding for our programs is generally linked to trends in U.S. government spending in the areas of defense, intelligence 
and homeland security.  While we believe that spending for national security and other programs we support will continue to be 
a priority, federal spending levels generally have come under pressure given mounting levels of debt.  The uncertainty about 
funding levels has led certain of our customers to delay awards and spending and led the government to policies adverse to our 
industry.  For example, during 2012 federal government service providers experienced an impact on profit margins as a result of  
pricing pressures from government customers.  We expect that our customers will continue to be motivated by minimizing cost, 
which we expect to lower margins across the whole industry.

While budgetary pressures and limitations have created a challenging environment for companies in our industry, we 
believe  that  this  situation  may  provide  opportunities  for  price  competitive  providers  such  as  ManTech  and  that  the  federal 
government's spending will remain robust in key areas for which ManTech is well positioned.  For example, changing mission 
priorities following the end of the Iraq war and the planned withdrawal from Afghanistan have and will continue to result in 
reduced spending in support of overseas contingency operations generally.  This change will impact the outlook for our industry 
overall, however we believe that ManTech is positioned to continue benefiting in the near term from our delivery of C4ISR and 
logistics services around the world, as evidenced by recent significant contract awards in these areas.

Revenues

Substantially all of our revenues are derived from services and solutions provided to the federal government or to prime 
contractors supporting the federal 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.

Several years ago, management decided to pursue a prime position on contracts by bidding as a prime and through the 

acquisition of companies holding a prime position on desired contract vehicles.  As a result, our prime contract revenues as a 
percentage of our total revenues have increased each year since 2008.  The following table shows our revenues as prime 
contractor and as subcontractor as a percentage of our total revenues for the following periods:

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.  

29

 
 
 
 
For cost-reimbursable contracts with performance-based fee incentives that are subject to the provisions of Securities and Exchange 
Commission (SEC) Topic 13, Revenue Recognition, we recognize the relevant portion of the fee upon customer approval.  

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.  

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 is 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.  

Our  contract  mix  varies  from  year-to-year  due  to  numerous  factors,  including  our  business  strategies  and  federal 
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.

The amount of risk and potential reward varies under each type of contract.  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.  Under time-and-material contracts, we assume 
financial risk because our labor costs may exceed the negotiated billing rates.  Profit margins on well-managed time-and material 
contracts tend to be higher than profit margins on cost-reimbursable contracts as long as we are able to staff those contracts with 
people who have an appropriate skill set.  Fixed-price contracts generally offer higher profit margins opportunities, but generally 
involve greater financial risk because we bear the impact of any cost overruns.  Our earnings and profitability may vary depending 
on changes in our contract mix.  Over the past several years, our customers have increasingly procured our services under cost-
reimbursable contracts. 

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-material contracts than cost-reimbursable contracts.  Fixed-price 
contracts generally offer higher profit margins opportunities but involve great financial risk because we bear impact of cost overruns 
in return for the full benefit of any cost savings.

30

 
 
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 
expense 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.

Interest Expense 

Interest expense is primarily related to interest expense incurred or accrued under our outstanding borrowings, our 7.25% 

senior secured notes and deferred financing charges. 

Interest Income

Interest income is primarily from cash on hand and notes receivable.

Revenues

The primary driver of our decrease in revenues relates to reductions on our C4ISR support contracts and contracts that 
have ended.  These reductions were partially offset by revenues provided from new contract awards in the intelligence area.  The 
reduction in C4ISR work is primarily due to reduced demand for field service support and delays in enhancements to existing ISR 
systems.

31

 
 
While there is significant budgetary uncertainty, we expect to perform strongly in 2013 as we take advantage of market 
share expansion opportunities through our competitive positioning in today's highly cost sensitive environment and use our strong 
balance sheet to pursue acquisitions targets in strategically important markets.

Cost of services 

The decrease in cost of services was primarily due to the decrease in revenues.  As a percentage of revenues, direct labor 
costs increased to 36.1% for the year ended December 31, 2012, as compared to 34.2% for the same period in 2011 as a result of 
an  increase  in  our  percentage  of  work  as  a  prime  contractor.   As  a  percentage  of  revenues,  other  direct  costs,  which  include 
subcontractors and third party equipment and materials used in the performance of our contracts, decreased from 51.3% for the 
year ended December 31, 2011 to 49.6% for the same period in 2012 due to a reduction in other direct costs on the C4ISR support 
contracts. 

General and administrative expenses 

The increase in general and administrative expense was primarily due to our acquisitions and facility related costs from 
newly leased office space.  We expect general and administrative expenses as a percentage of revenues in 2013 to decline slightly 
compared to 2012 as we have instituted numerous cost reduction initiatives.

Other income (expense), net

The decrease in other income (expense), net was due to the sale of our investment in NetWitness in April 2011, which 

resulted in a gain of $3.7 million for the year ended December 31, 2011.

Provision for income taxes

Our effective income tax rates were 38.7% and 38.1% for the years ended December 31, 2012 and 2011, respectively.  
Our tax rate is affected by recurring items, such as tax rates and the relative amount of income we earn in jurisdictions, which we 
expect to be fairly consistent in the near term.  It is also affected by discrete items that may occur in any given year, but are not 
consistent from year to year.  The difference between our statutory U.S. federal income tax rate of 35.0%  and our effective tax 
rate is state income taxes and non-deductible compensation.

Net income 

The decrease was due to lower revenues, increased general and administrative expenses and margin pressure on our new 
contracts, both from the shift in contract type to cost-reimbursable and increased competitive market place.  We expect additional 
pressure  on  future  levels  of  net  income  as  a  percentage  of  revenues  as  the  trend  towards  cost-reimbursable  contract  awards, 
increased competition and pricing pressures continue to impact our operating margin.

Revenue growth of $176.8 million came from organic growth due to contract awards and expansion on prime positions 
in our  C4ISR support business,  including the S3 contract vehicle.   Our acquisitions of S&IS,  MTCSC, TranTech and WINS 
contributed revenue growth of $128.8 million.  These increases were partially offset by a decrease in our global logistic services 
contracts.

Cost of services 

The increase in cost of services was primarily due to our acquisitions and continued organic growth.  Direct labor costs, 
which include applicable fringe benefits and overhead, increased 8.2% for the year ended December 31, 2011 over the same period 
in 2010, primarily due to our acquisitions.  As a percentage of revenues, direct labor costs decreased to 34.2% for the year ended 
December 31, 2011, as compared to 34.8% for the same period in 2010.  Other direct costs, which include subcontractors and 
third party equipment and materials used in the performance of our contracts, increased by 13.1% for the year ended December 31, 
2011 over the same period in 2010.  As a percentage of revenues, other direct costs increased from 50.0% for the year ended 
December 31, 2010 to 51.3% for the same period in 2011.  The increase of other direct costs as a percentage of revenues was 
primarily due to increasing subcontractor costs related to our increasing position as a prime on contracts. 

General and administrative expenses 

The increase in general and administrative expense was primarily due our acquisitions, higher bid and proposal expenses 
driven by a few large proposals, higher expenses for non-recurring legal services related to a case in which the Company is the 
plaintiff and stock-based compensation expenses increased due to higher forfeitures in 2010 resulting from the resignation of the 
Company's former Chief Operating Officer.  As a percentage of revenues, general and administrative expenses decreased due to 
the leveraging of our general and administrative expense over a larger base.  

Interest expense 

The increase in interest expense was primarily related to our 7.25% senior unsecured notes being outstanding for all of 
2011 as compared to nine months of  2010.  We incurred $15.0 million of interest expense for the year ended December 31, 2011 
related to our 7.25% senior unsecured notes issued in April 2010. 

33

Other income (expense), net

The increase in other income (expense), net was due to the sale of our investment in NetWitness, which resulted in a gain 

of $3.7 million for the year ended December 31, 2011.

Provision for income taxes

Our effective income tax rates were 38.1% and 38.2% for the years ended December 31, 2011 and 2010, respectively.  

Net income 

The increase in net income was due to higher revenues as well as a gain we recorded due to the sale of an investment.   

Backlog 

For the years ended December 31, 2012, 2011 and 2010 our backlog was $6.5 billion, $4.7 billion and $4.9 billion, 
respectively, of which $1.8 billion, $1.3 billion and $1.6 billion, respectively, was funded backlog.  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, 2012, the Company's cash and cash equivalents balance was $134.9 million.  At December 31, 2012, 
there was no outstanding balance under our revolving credit facility.  At December 31, 2012, we were contingently liable under 
letters of credit totaling $0.2 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, 2012 was $499.8 million.  At December 31, 
2012, we had $200.0 million outstanding of our 7.25% senior unsecured notes.  

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 is necessary from time-to-time to increase 
borrowings under our revolving credit facility to meet cash demands.

Our operating cash flow is primarily affected by our ability to invoice and collect from our customers 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.  Cash flow from operations decreased during the year ended December 31, 2012 compared to the same 
period in 2011 due to decreased billings in excess, lower net income, increased contractual inventory, timing of salaries payable 
and an increase in our days sales outstanding (DSO), which were partially offset by timing of vendor payables and deferred income 
taxes.  Contractual inventory relates to equipment on one of our intelligence contracts that was delivered in 2013.  Our accounts 
receivable DSO ratio, based on fourth quarter sales, was 79 and 71 at December 31, 2012 and 2011, respectively.  Increased cash 
flow  from  operations  during  the  year  ended  December 31,  2011  compared  to  the  same  period  in  2010  was  due  to  increased 
receivables,  depreciation  expense  and  billings  in  excess  of  revenue  earned  primarily  related  to  a  contract  to  provide  mobile 
telecommunication  services  in Afghanistan,  and  net  income,  partially  offset  by  the  timing  of  vendor  payables  and  decreased 
deferred income taxes.

business of HBGary, Inc. for $23.8 million and Evolvent Technologies, Inc. for $38.9 million net of cash acquired and capital 
expenditures of $14.9 million. Cash outflows in 2011 were due to the purchase of property and equipment of $54.5 million primarily 
related to a mobile telecommunication network built for use on one of our contracts in Afghanistan and the acquisition of WINS 
for $87.1 million and TranTech for $20.2 million.  Cash outflows in 2010 were primarily due to the acquisitions of STI, S&IS and

Cash outflow from financing activities during 2012 resulted primarily from the dividends paid of $31.0 million, offset 
by the proceeds from the exercise of stock options for $1.1 million.  Cash outflow from financing during 2011 resulted primarily 
from the dividends paid of $30.8 million and debt issuance costs of $3.9 million for our revolving credit facility, offset by the 
proceeds from the exercise of stock options for $8.2 million. Cash flow from financing during 2010 resulted primarily from the 
issuance of 7.25% senior unsecured notes for $200.0 million and the proceeds from the exercise of stock options for $13.8 million, 
offset by debt issuance costs of $5.0 million. 

Revolving Credit Facility 

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 $500.0 million revolving credit facility, with a $25.0 million letter of credit sublimit and a $30.0 
million swing line loan sublimit.  The credit agreement also contains an accordion feature that permits the Company to arrange 
with the lenders for the provision of up to $250.0 million in additional commitments.  The maturity date for this agreement is 
October 12, 2016.  

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-rate spreads (1.25% to 2.25% based on 
the Company's consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on 
the Company's 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 a certain leverage ratios and a certain fixed charge 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  additional  actions.   As  of,  and  during, 
December 31, 2012 and 2011, we were in compliance with our financial covenants under the credit agreement.  

There was no outstanding balance on our revolving credit facility at December 31, 2012 and 2011.

7.25% Senior Unsecured Notes

We have $200.0 million in aggregate principal amount of 7.25% senior unsecured notes that are registered under the 

Securities Act of 1933, as amended.  The 7.25% senior unsecured notes were issued April 13, 2010.  

The indenture governing the 7.25% senior unsecured notes contains customary events of default, as well as restrictive 
covenants, which, subject to important exceptions and qualifications specified in such indenture, will, among other things, limit 
our ability and the ability of our subsidiaries that guarantee the 7.25% senior unsecured notes to: pay dividends or distributions, 
repurchase equity, prepay subordinated debt or make certain investments; incur additional debt or issue certain disqualified stock 
and preferred stock; incur liens on assets; merge or consolidate with another company or sell all or substantially all assets; and 
allow to exist certain control provisions.  As of December 31, 2012 and 2011, the Company was in compliance with all covenants 
required by the indenture.

Capital Resources

We believe the capital resources available to us from cash on hand of $134.9 million at December 31, 2012, our $500.0 
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; additional senior unsecured notes; and additional borrowing 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 under our revolving credit facility bear interest at one of the following variable 
rate as selected by the Company at the time of the borrowing: a LIBOR based rate plus market spreads (1.25% to 2.25% based 
on the Company's consolidated total leverage ratio) or the Bank of America's base rate plus market spreads (0.25% to 1.25% based 
on the Company's consolidated total leverage ratio).  In April of 2010, we used the proceeds from the issuance of the 7.25% senior 
unsecured notes to repay all outstanding borrowings under our revolving credit facility.  In the next year we may use, as needed, 
our revolving credit facility or additional sources of borrowings in order to fund anticipated cash requirements.

The following table summarizes the activity under our revolving credit facility for the years ended December 31, 

2012, 2011 and 2010:

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 year ended December 31, 2012, we declared and paid quarterly dividends, each in the amount of $0.21 per 
share on all issued and outstanding shares of common stock.  During the year ended December 31, 2011, we declared and paid 
semi-annual dividends, each in the amount of $0.42 per share on all issued and outstanding shares 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

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. 

37

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, that are 
subject to the provisions of ASC 605-35, Construction-Type and Certain Production-Type 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.  For cost-reimbursable contracts 
with performance-based fee incentives that are subject to the provisions of SEC Topic 13, Revenue Recognition, we recognize the 
relevant portion of the fee upon customer approval.  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 and 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 first step of the impairment test does not indicate an impairment, performance of the second step is not required.  

The fair values of the reporting units are determined based on a weighting of the income approach, market approach and 
the market transaction approach.  The income approach is a valuation technique in which fair value is derived 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 is 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 

38

 
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).  We compare 
our implied control premium to the control premiums in comparable transactions to assess the reasonableness of our calculations.   

We have elected to perform our annual review during the second quarter of each calendar year.  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 or circumstances that could cause the fair value 
of our long-lived assets to decrease include changes in our business environment or market conditions.  For example, the U.S. 
government is currently under pressure to decrease its spending, and reductions across our industry may be mandated in connection 
with sequestration.  The impact of reduced government spending on our programs and industry could materially affect our financial 
outlook.  A significant adverse impact to our financial outlook could result in impairments to our long-term assets, such as goodwill 
and other intangible assets.  Additionally, deteriorating market conditions for comparable public companies in our industry, or a 
material decline in the market price for the Company's stock, could result in a reduction in the fair value of our assets.  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 the Company's 

recorded goodwill, differences in assumptions may have a material effect on the results of the Company's impairment analysis.

Accounting Standards Updates

In July 2012, Accounting Standard Update No. 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-
Lived Intangible Assets for Impairment, was issued.  The amendments in this Update apply to all entities, both public and nonpublic, 
that have indefinite-lived intangible assets, other than goodwill, reported in their financial statements.  In accordance with the 
amendments in this Update, an entity has the option first to assess qualitative factors to determine whether the existence of events 
and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired.  If, after assessing 
the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible 
asset is impaired, then the entity is not required to take further action.  However, if an entity concludes otherwise, then it is required 
to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the 
fair value with the carrying amount in accordance with Subtopic 350-30.  An entity also has the option to bypass the qualitative 
assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment 
test.  An entity will be able to resume performing the qualitative assessment in any subsequent period.  In conducting a qualitative 
assessment, an entity should consider the extent to which relevant events and circumstances, both individually and in the aggregate, 
could have affected the significant inputs used to determine the fair value of the indefinite-lived intangible asset since the last 
assessment.  An entity also should consider whether there have been changes to the carrying amount of the indefinite-lived intangible 
asset when evaluating whether it is more likely than not that the indefinite-lived intangible asset is impaired.  An entity should 
consider positive and mitigating events and circumstances that could affect its determination of whether it is more likely than not 
that the indefinite-lived intangible asset is impaired.  An entity should refer to the examples in paragraph 350-30-35-18B(a) through 
(f) for guidance about the types of events and circumstances that it should consider in evaluating whether it is more likely than 
not that an indefinite-lived intangible asset is impaired.  If an entity has made a recent fair value calculation that indicated a 
difference between the fair value and the then carrying amount of an indefinite-lived intangible asset, that difference also should 
be included as a factor in considering whether it is more likely than not that the indefinite-lived intangible asset is impaired.  The 
amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012.  
Early adoption is permitted, including for annual and interim impairment tests performed as of a date before July 27, 2012, if a 
public entity's financial statements for the most recent annual or interim period have not yet been issued or, for nonpublic entities, 
have not yet been made available for issuance.  The adoption of Accounting Standard Update No. 2012-02 is not expected to have 
an impact on the Company's results of operations or financial position.

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, 2012, 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 no effect on our annual interest expense 
for the year ended December 31, 2012.

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.  

39

 
 
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.

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,  2012  and  2011,  and  the  related  consolidated  statements  of  income,  comprehensive  income, 
changes in stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2012.  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, 2012 and 2011, and the results of their operations and their cash 
flows for each of the three years in the period ended December 31, 2012, 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, 2012, based on the criteria established in Internal Control-
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated 
February 22, 2013 expressed an unqualified opinion on the Company's internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Years Ended December 31, 2012, 2011 and 2010 

1. 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; departments of Defense, State, Homeland Security, Energy and Justice, including the Federal Bureau of 
Investigation (FBI); healthcare and space communities; and other U.S. federal government customers.  We provide support to 
critical national security programs for approximately 50 federal agencies through approximately 1,000 current contracts.  Our 
services  include  the  following  solution  sets  that  are  aligned  with  the  long-term  needs  of  our  customers:  command,  control, 
communications, computers, intelligence, surveillance and reconnaissance (C4ISR) solutions and services; cyber security; global 
logistics  support;  information  technology  (IT)  modernization  and  sustainment;  intelligence/counter-intelligence  solutions  and 
support; systems engineering; test and evaluation; environmental, range and sustainability services; and healthcare analytics and 
IT.  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, wholly-owned subsidiaries and other entities, which we control.  Our share of affiliates' earnings (losses) that we do 
not  control  is  included  in  our  consolidated  statements  of  income  using  the  equity  method.   All  inter-company  accounts  and 
transactions have been eliminated. 

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, 2012 was not material to our consolidated financial 
statements.

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,  that  are  subject  to  the  provisions  of ASC  605-35,  Construction-Type  and  Certain  Production-Type  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.  For cost-
reimbursable  contracts  with  performance-based  fee  incentives  that  are  subject  to  the  provisions  of  SEC  Topic  13,  Revenue 
Recognition, we recognize the relevant portion of the fee upon customer approval.  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 

48

 
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. 

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.  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-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  and  Other  Intangibles-net-Goodwill  represents  the  excess  of  cost  over  the  fair  value  of  net  tangible  and 
identifiable intangible assets of acquired companies.  Contract rights and other intangibles 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 intangibles, net. 

Software Development Costs-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.  
We recorded $0, $0 and $0.2 million per year of amortization expense on capitalized software cost for sale for the years ended 
December 31, 2012, 2011 and 2010, respectively.  There were no capitalized software costs for sale included in other intangibles, 
net at December 31, 2012 and 2011. 

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 
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. 

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 have elected to perform our annual review during the second quarter 
of each calendar year.  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.  No adjustments were necessary as a result of our annual review 
during the quarter ended June 30, 2012.

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 
49

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.   See Note 10 for further discussion regarding stock-based compensation.

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-Comprehensive income is presented in our consolidated statements of changes in stockholders' 
equity.  Comprehensive income consists of net income; 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 values. 

Accounting Standards Updates 

In July 2012, Accounting Standard Update No. 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-
Lived Intangible Assets for Impairment, was issued.  The amendments in this Update apply to all entities, both public and nonpublic, 
that have indefinite-lived intangible assets, other than goodwill, reported in their financial statements.  In accordance with the 
amendments in this Update, an entity has the option first to assess qualitative factors to determine whether the existence of events 
and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired.  If, after assessing 
the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible 
asset is impaired, then the entity is not required to take further action.  However, if an entity concludes otherwise, then it is required 
to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the 
fair value with the carrying amount in accordance with Subtopic 350-30.  An entity also has the option to bypass the qualitative 
assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment 
test.  An entity will be able to resume performing the qualitative assessment in any subsequent period.  In conducting a qualitative 
assessment, an entity should consider the extent to which relevant events and circumstances, both individually and in the aggregate, 
could have affected the significant inputs used to determine the fair value of the indefinite-lived intangible asset since the last 
assessment.  An entity also should consider whether there have been changes to the carrying amount of the indefinite-lived intangible 
asset when evaluating whether it is more likely than not that the indefinite-lived intangible asset is impaired.  An entity should 
consider positive and mitigating events and circumstances that could affect its determination of whether it is more likely than not 
that the indefinite-lived intangible asset is impaired.  An entity should refer to the examples in paragraph 350-30-35-18B(a) through 
(f) for guidance about the types of events and circumstances that it should consider in evaluating whether it is more likely than 
not that an indefinite-lived intangible asset is impaired.  If an entity has made a recent fair value calculation that indicated a 
difference between the fair value and the then carrying amount of an indefinite-lived intangible asset, that difference also should 
be included as a factor in considering whether it is more likely than not that the indefinite-lived intangible asset is impaired.  The 
50

 
amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012.  
Early adoption is permitted, including for annual and interim impairment tests performed as of a date before July 27, 2012, if a 
public entity's financial statements for the most recent annual or interim period have not yet been issued or, for nonpublic entities, 
have not yet been made available for issuance.  The adoption of Accounting Standard Update No. 2012-02 is not expected to have 
an impact on the Company's results of operations or financial position.

3. Acquisitions 

Our  acquisitions  have  been  accounted  for  using  the  acquisition  method  of  accounting  under  ASC  805,  Business 

Combinations.    

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 
infrastructure and technology sectors.  This acquisition broadened our cyber security solution capability for customers.  ManTech 
funded  the  acquisition  with  cash  on  hand.   The  preliminary  purchase  price  was  $23.8  million  and  may  increase  or  decrease 
depending  on  the  finalization  of  the  post-closing  working  capital  adjustment. The  asset  purchase  agreement  did  not  contain 
provisions for contingent consideration. 

Revenues were $3.2 million and net loss was $3.2 million for the period from April 2, 2012 to December 31, 2012.  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 expense in our consolidated statement of income. 

The preliminary 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 intangibles 
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 relationship 
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 estimate useful lives of approximately 3 years, 2 years and 2 
years, respectively.  The weighted-average amortization period for the intangible assets is 2.5 years.

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.   

Revenues were $27.9 million and net income was $0.3 million for the period from January 6, 2012 to December 31, 2012.  
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 expense in our consolidated statement of income.   

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 

51

the highly skilled employees and the value paid for Evolvent's capabilities in providing IT services and solutions to the federal 
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 18.5 years. 

Worldwide Information Network Systems, Inc.-On November 15, 2011, we completed the acquisition of Worldwide 
Information Network Systems, Inc. (WINS).  The results of WINS' operations have been included in our consolidated financial 
statements since that date.  The acquisition was completed through a stock purchase agreement dated October 26, 2011, by and 
among a subsidiary of ManTech International Corporation, WINS and its sole shareholder.  WINS provides IT solutions with 
network engineering and cyber security technical expertise to the Department of Defense, Department of State and other agencies.  
WINS' largest customer is the Defense Intelligence Agency (DIA) through its prime position on the Solutions for the Information 
Technology Enterprise (SITE) Indefinite Delivery/Indefinite Quantity contract vehicle.   This acquisition broadened our footprint 
in the high-end defense and intelligence market.  The addition of WINS' IT capabilities, its prime position on the DIA SITE 
contract, support of the Department of State and other contracts will enhance our positioning with important customers and further 
our growth prospects.   ManTech funded the acquisition with cash on hand.  The stock purchase agreement did not contain provisions 
for contingent consideration.  

The Company incurred in fiscal year 2011 approximately $0.6 million of acquisition costs related to the WINS transaction, 
which are included in general and administrative expense in our consolidated statement of income for the year ended December 
31, 2011. 

The purchase price of $90.4 million was allocated to the underlying assets and liabilities based on their fair values at the 
date of acquisition.  Total assets were $100.5 million, including goodwill and intangible assets recognized in connection with the 
acquisition, and total liabilities were $10.1 million.  Included in total assets were $18.7 million in acquired intangible assets.  We 
recorded goodwill of $62.5 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 highly skilled employees and the value paid for WINS' capabilities 
in supporting high-end defense, intelligence and homeland security markets.  

In  allocating  the  purchase  price,  we  consider  among  other  factors,  analyses  of  historical  financial  performance  and 
estimates of future performance of WINS' contracts.  The components of other intangible assets associated with the acquisition 
were customer relationships and backlog valued at $18.0 million and $0.7 million, respectively.  Customer contracts and related 
relationships represent the underlying relationships and agreements with WINS' 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 19.3 years.

TranTech,  Inc.-On  February 11,  2011,  we  completed  the  acquisition  of  TranTech,  Inc.  (TranTech).    The  results  of 
TranTech's operations have been included in our consolidated financial statements since that date.  The acquisition was completed 
through a stock purchase agreement dated February 11, 2011, by and among ManTech International Corporation, TranTech and 
its sole shareholder.  TranTech provides information technology, networking and cyber security services to the federal government.  
This acquisition allows us to continue extending our presence in the defense, security and intelligence communities, and to offer 
comprehensive solutions through a prime position on the Defense Information Systems Agency ENCORE II contract.  ManTech 
funded the acquisition with cash on hand.  The stock purchase agreement did not contain provisions for contingent consideration.   

The  Company  incurred  in  fiscal  year  2011  approximately  $0.3  million  of  acquisition  costs  related  to  the  TranTech 
transaction, which are included in general and administrative expense in our consolidated statement of income for the year ended 
December 31, 2011. 

The purchase price of $21.5 million was allocated to the underlying assets and liabilities based on their fair value at the 
date of acquisition.  Total assets were $23.8 million, including goodwill and intangible assets recognized in connection with the 
acquisition, and total liabilities were $2.3 million.  Included in total assets were $5.0 million in acquired intangible assets.  We 
recorded goodwill of $14.6 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 TranTech's capabilities in supporting high-end defense,

In  allocating  the  purchase  price,  we  consider  among  other  factors,  analyses  of  historical  financial  performance  and 
estimates of future performance of TranTech's contracts.  The components of other intangible assets associated with the acquisition 
were customer relationships and backlog valued at $4.6 million and $0.4 million, respectively.  Customer contracts and related 
relationships represent the underlying relationships and agreements with TranTech'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 intangibles assets is 18.5 years. 

MTCSC, Inc.-On December 23, 2010, we completed the acquisition of MTCSC, Inc. (MTCSC).  The results of MTCSC's 
operations have been included in our consolidated financial statements since that date.  The acquisition was consummated pursuant 
to a stock purchase agreement dated November 19, 2010, by and among ManTech International Corporation and MTCSC, Inc 
and its shareholders.  MTCSC provides C4ISR systems, integration, cyber security and network engineering solutions to U.S. 
government  customers.   The  acquisition allows  us  to  expand  our  work  and  direct  support  to  the  United  States  Marine  Corp.  
ManTech funded the acquisition with cash on hand.  The stock purchase agreement did not contain provisions for contingent 
consideration.

The  Company  incurred  in  fiscal  year  2010  approximately  $0.7  million  of  acquisition  costs  related  to  the  MTCSC 
transaction, which are included in general and administrative expense in our consolidated statement of income for the year ended 
December 31, 2010. 

The purchase price of $76.7 million was allocated to the underlying assets and liabilities based on their fair values at the 
date of acquisition.  Total assets were $94.7 million, including goodwill and intangible assets recognized in connection with the 
acquisition, and total liabilities were $18.0 million.  Included in total assets were $8.7 million in acquired intangible assets.  We 
have recorded goodwill of $60.1 million, which will not be deductible for tax purposes.  Recognition of goodwill is largely attributed 
to the highly skilled employees and the value paid for MTCSC's capabilities in supporting high-end defense, intelligence and 
homeland security markets.  

In allocating the purchase price, we considered among other factors, analysis of historical financial performance and 
estimates of future performance of MTCSC's contracts.  The components of other intangible assets associated with the acquisition 
were customer relationships and backlog valued at $8.1 million and $0.6 million, respectively.  Customer contracts and related 
relationships represent the underlying relationships and agreements with MTCSC'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 18.7 years.

QinetiQ  North  America's  Security  and  Intelligence  Solutions  Business-On  October 8,  2010,  we  completed  the 
acquisition of certain assets of QinetiQ North America, Inc. (QNA) Security and Intelligence Solutions (S&IS) business unit.  The 
results of S&IS's operations have been included in our consolidated financial statements since that date.  The acquisition was 
completed through an asset purchase agreement dated September 29, 2010, by and among a subsidiary of ManTech International 
Corporation; QNA, Inc.; and certain subsidiaries of QNA.  S&IS provides integrated security solutions to the Department of 
Defense and the intelligence community.  The acquisition is consistent with ManTech's long-term strategy to extend our presence 
in the defense and intelligence market, allowing us to offer comprehensive solutions for the full range of security threats from 
physical  through  cyber.    ManTech  funded  the  acquisition  with  cash  on  hand.   The  asset  purchase  agreement  did  not  contain 
provisions for contingent consideration. 

In  fiscal  years  2011  and  2010,  the  Company  incurred  approximately  $0.1  million  and  $0.7  million,  respectively,  of 
acquisition costs related to the S&IS transaction, which are included in general and administrative expense in our consolidated 
statement of income for the years ended December 31, 2011 and 2010. 

The purchase price of $60.0 million was allocated to the underlying assets and liabilities based on their fair values at the 
date of acquisition.  Total assets were $62.0 million, including goodwill and intangible assets recognized in connection with the 
acquisition, and total liabilities were $2.0 million.  Included in total assets were $13.0 million in acquired intangible assets.  We 
have recorded goodwill of $40.3 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 highly skilled employees and the value paid for S&IS's 
capability in supporting high-end defense, intelligence and homeland security markets.  

In allocating the purchase price, we consider among other factors, analysis of historical financial performance and estimates 
of future performance of S&IS's contracts.  The components of other intangible assets associated with the acquisition were customer 
relationships and backlog valued at $11.5 million and $1.5 million, respectively.  Customer contracts and related relationships 
represent the underlying relationships and agreements with S&IS's existing customers.  Customer relationships and backlog are 

53

    
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 17.9 years.

Sensor Technologies Inc.-On January 15, 2010, we completed the acquisition of all outstanding equity interests of Sensor 
Technologies Inc. (STI), a privately-held company.  The results of STI's operations have been included in our consolidated financial 
statements since that date.  The acquisition was consummated pursuant to a stock purchase agreement, dated December 18, 2009, 
by and among ManTech, STI, certain shareholders of STI and certain persons acting as a representative for the shareholders of 
STI.  STI provides mission-critical systems engineering and C4ISR services and solutions to the Department of Defense.  STI's 
largest customer was the U.S. Army through its prime position on the S3 Indefinite Delivery/Indefinite Quantity contract.  The 
acquisition of STI is consistent with our long-term strategy to broaden our footprint in the high-end defense and intelligence 
market, allowing us to expand our work with the Department of Defense and our direct support of the U.S. Army as it continues 
its overseas operations.  ManTech 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.  

In fiscal year 2010, the Company incurred $0.2 million of acquisition costs related to STI transaction, which are included 

in general and administrative expense in our consolidated statement of income for the year ended December 31, 2010. 

The purchase price of $241.4 million was allocated to underlying assets and liabilities based on their estimated fair values 
at the date of acquisition.  The purchase price allocation included goodwill and other intangible assets.  Recognition of goodwill 
was largely attributed to the highly skilled employees of STI, their presence in the high-end defense and intelligence market place.  
Assuming adequate levels of taxable income, the goodwill is deductible for tax purposes over 15 years.  The following table 
represents the purchase price allocation (in thousands):

Pursuant  to  the  stock  purchase  agreement,  the  seller  has  agreed  to  indemnify  the  buyer  for  tax  liabilities  arising  in 
connection with the operation of STI's business on or before January 15, 2010 or owing by any person for which STI may be liable 
as a result of the transactions or circumstances occurring or existing on or before January 15, 2010.  As of January 15, 2010, STI's 
tax liabilities were approximately $0.8 million, resulting in related indemnification assets of $0.8 million.  

In allocating the purchase price, we considered among other factors, analysis of historical financial performance and 
estimates of future performance of STI's contracts.  The components of other intangible assets associated with the acquisition were 
customer relationships, backlog and non-compete agreements valued at $85.2 million, $7.8 million and $0.3 million, respectively.  
Customer contracts and related relationships represent the underlying relationships and agreements with STI's existing customers.  
Non-compete agreements represent the estimated value of the seller not competing with the Company for 4 years.  Customer 
relationships, backlog and non-compete agreements are amortized over their estimated useful lives of 20 years, 1 year and 4 years, 
respectively, using the pattern of benefits method.  The weighted-average amortization period for the intangible assets is 18.4 
years.

Pro Forma Financial Information-We calculated the following unaudited pro forma amounts as if our acquisitions had 
occurred on January 1, 2011.  Our consolidated pro forma revenue would have been $2,584.5 million and $2,980.3 million and 
our consolidated pro forma net income would have been $95.9 million and $130.5 million for the years ended December 31, 2012 
and 2011, respectively.

4. Earnings per Share 

Under ASC 260, Earnings per Share, the two-class method is an earnings allocation formula that determines earnings 
per share for each class of common stock according to dividends declared (or accumulated) and participation rights in undistributed 
earnings.  Under that method, basic and diluted earnings per share data are presented for each class of common stock.

In applying the two-class method, we determined that undistributed earnings should be allocated equally on a per share 
basis between Class A and Class B common stock.  Under the Company's 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 2012, we declared and paid quarterly dividends, each in the 
amount of $0.21 per share on both classes of common stock.  During 2011, we declared and paid semi-annual dividends, each in 
the amount of $0.42 per share on both classes of common stock.  

Basic earnings per share has been computed by dividing net income 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 per share has 
been computed in a manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common 
shares that were outstanding during each period. 

The calculation of numerator and denominator in earnings per share is computed as follows (in thousands):

would have been anti-dilutive.  For the years ended December 31, 2012, 2011 and 2010, shares issued from the exercise of stock 
options were 38,542; 271,165; and 391,176, respectively.

5. Revenues and 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.  Revenues from the U.S. government under prime contracts 
and  subcontracts,  as  compared  to  total  contract  revenues,  were  approximately  99.2%,  99.2%  and  98.7%  for  the  years  ended 
December 31, 2012, 2011 and 2010, respectively.  The components of contract receivables are as follows (in thousands):

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.  Revenues recorded in excess of milestone 
billings on fixed price contracts consist of amounts not expected to be billed within the next month.  The retainage is billable upon 
completion of the contract performance and approval of final indirect expense rates by the government.  Accounts receivable at 
December 31, 2012 are expected to be substantially collected in 2013 except for approximately $1.5 million, of which 91.3% 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 the Company's estimate 
for exposure to compliance, contractual issues and bad debts related to prime contractors.

7. Goodwill and Other Intangibles 

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.  We have elected to 
perform this review during the second quarter of each calendar year.  The goodwill impairment test is a two-step process performed 
at the reporting unit level.  If the first step of the impairment test does not indicate an impairment, performance of the second step 
is not required.  The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount 
(including goodwill).  The fair values of the reporting units are determined based on a weighting of the income approach, market 
approach and market transaction approach.

56

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). We compared 
our implied control premium to the control premiums in comparable transactions to assess the reasonableness of our calculations.  
Based on this comparison the implied control premium appeared reasonable.   

During the second quarter, we completed our annual goodwill impairment test.  The results of step one of this test showed 
the fair value of all reporting units were substantially in excess of their carrying value, therefore, no impairment losses were 
identified and performance of step two was not required.  We continue to monitor events that could impact our financial outlook 
and our assets including potential significant reductions in government spending that could adversely impact our financial results 
and changes in market conditions that could result in a reduction in the fair value of our assets.

Revolving Credit Facility-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 $500.0 million revolving credit facility, with a $25.0 million letter of 
credit sublimit and a $30.0 million swing line loan sublimit.  The credit agreement also contains an accordion feature that permits 
the Company to arrange with the lenders for the provision of up to $250.0 million in additional commitments.  During 2011, we 
incurred $3.9 million in debt issuance costs related to the credit agreement, which have been deferred and amortized over the term 
of the agreement.  The maturity date for this agreement is October 12, 2016.  

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-rate spreads (1.25% to 2.25% based on 
the Company's consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on 
the Company's consolidated total leverage ratio).  The aggregate annual weighted average interest rates were 0.05% and 0.00% 
for the years ended December 31, 2012 and 2011, respectively.

58

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 a certain consolidated leverage ratios and a certain fixed charge 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  additional  actions.   As  of,  and  during, 
December 31, 2012 and 2011, we were in compliance with our financial covenants under the credit agreement.  

On October 12, 2011, we terminated the commitments under our prior credit agreement, dated April 30, 2007.

There was no outstanding balance on our revolving credit facility at December 31, 2012 and 2011.  The weighted average 
borrowings under the revolving portion of the facility during the years ended December 31, 2012 and 2011 were $38 thousand 
and $0, respectively.  The maximum available borrowing under the revolving credit facility at December 31, 2012 was $499.8 
million.  At December 31, 2012 and 2011, we were contingently liable under letters of credit totaling $0.2 million and $1.2 million, 
respectively, which reduces our availability to borrow under our revolving credit facility.

The following table summarizes the activity under our revolving credit facility for the years ended December 31, 2012,

7.25% Senior Unsecured Notes-We have $200.0 million in aggregate principal amount of 7.25% senior unsecured notes 
that are registered under the Securities Act of 1933, as amended.  The 7.25% senior unsecured notes were issued April 13, 2010. 

The 7.25% senior unsecured notes mature on April 15, 2018 with interest payable semi-annually in April and October.   

The 7.25% senior unsecured notes were issued at 100% of the aggregate principal amount and are effectively subordinate to the 
Company's existing and future senior secured debt (to the extent of the value of the assets securing such debt), including debt 
outstanding under our revolving credit facility.  The 7.25% senior unsecured notes may be redeemed, in whole or in part, at any 
time, at the option of the Company, subject to certain conditions specified in the indenture governing the 7.25% senior unsecured 
notes.  The 7.25% senior unsecured notes are guaranteed, jointly and severally, on a senior unsecured basis by each of our 100% 
owned domestic subsidiaries that also guarantees debt obligations under our prior revolving credit facility or will guarantee debt 
obligations under our revolving credit facility.

The fair value of the 7.25% senior unsecured notes as of December 31, 2012 was approximately $211.0 million based 

on quoted market prices.

The Company incurred approximately $4.9 million in issuance costs, which are being amortized to interest expense over 
the contractual life of the 7.25% senior unsecured notes using the effective interest rate method, resulting in an effective rate of 
7.67%.

The indenture governing the 7.25% senior unsecured notes contains customary events of default, as well as restrictive 
covenants, which, subject to important exceptions and qualifications specified in such indenture, will, among other things, limit 
our ability and the ability of our subsidiaries that guarantee the 7.25% senior unsecured notes to: pay dividends or distributions, 
repurchase equity, prepay subordinated debt or make certain investments; incur additional debt or issue certain disqualified stock 
and preferred stock; incur liens on assets; merge or consolidate with another company or sell all or substantially all assets; and 
allow to exist certain control provisions.  An event of default under the indenture will allow either the trustee of the notes or the 
holders of at least 25% in principal amount of the then outstanding notes to accelerate, or in certain cases, will automatically cause 
the acceleration of, the amounts due under the notes.  As of December 31, 2012 and 2011, the Company was in compliance with 
all required covenants under the indenture.

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 the Company's 
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 the Company's 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 2002 and the majority of the audits for 2003, 2004 and 2005, with no material 
adjustments.  The remaining audits for 2003 through 2012 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, 2012, aggregate future minimum rental commitments under these leases are as follows

Office space and equipment rent expense totaled approximately $52.1 million, $55.2 million and $47.9 million for the 

years ended December 31, 2012, 2011 and 2010, respectively. 

We had $9.3 million and $7.1 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, 2012 and 2011, respectively. 

10. Stockholders' Equity and Stock Options 

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, 2012, there were 23,849,719 
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 

60

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, 2012 and 2011, 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 stockholders approved our 2011 Management Incentive Plan (the Plan), which 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, 
2013, there were 555,638 additional shares made available for issuance under the Plan.  Through December 31, 2012, the remaining 
aggregate number of shares of our common stock authorized for issuance under the Plan was 3,048,209.  Through December 31, 
2012, there were 4,512,742 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, 2012, 2011 and 2010, we recorded $8.1 million, $9.2 
million and $7.4 million of stock-based compensation expense, respectively.  No compensation expense for employees with stock 
awards, including stock-based compensation expense, was capitalized during the periods.  For the years ended December 31, 2012, 
2011 and 2010, the total recognized tax deficiency from the exercise of stock options, vested cancellations and vesting of restricted 
stock were $1.4 million, $0.2 million and $0.4 million, respectively.

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, 2012 and 2011, 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, 2012, 

2011 and 2010:

Volatility-The expected volatility of the options granted was estimated based upon historical volatility of the Company's 

share price through weekly observations of the Company's trading history.

Expected Term-The expected term of options granted to employees during fiscal years 2012, 2011 and 2010 was determined 
from historical exercises of the grantee population.  For all grants valued during fiscal years 2012, 2011 and 2010, 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.

61

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 expected term of the underlying grants.  

Dividend Yield-The Black-Scholes-Merton valuation model requires an expected dividend yield as an input.  During 
fiscal year 2011, we initiated a cash dividend program.  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, 2012, 2011 and 2010:

Stock Option Activity-During the year ended December 31, 2012, we granted stock options to purchase 986,650 shares 
of class A common stock at a weighted-average exercise price of $29.24 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, 2012, 2011 
and 2010, as determined under the Black-Scholes-Merton valuation model, was $5.19, $9.14 and $12.87, 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, 2012, 2011 and 2010 had a combined 
fair value of $8.3 million, $7.8 million and $7.7 million, respectively.

Unrecognized compensation expense related to outstanding stock options expected to vest as of December 31, 2012 was 
$7.6 million, which is expected to be recognized over a weighted-average period of 1.9 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 issued 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 vesting dates.  Restricted shares issued 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.

11. Retirement Plans 

As of December 31, 2012, 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 
$22.6 million, $23.8 million and $22.9 million for the years ended December 31, 2012, 2011 and 2010, respectively. 

We maintained an Employee Stock Ownership Plan (ESOP) as of December 31, 2012.  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, 2012, 2011 and 2010, we recorded $3.8 million, $3.6 million and $3.4 
million, respectively, as compensation expense related to ESOP contributions.  Shares contributed to the ESOP for the years ended 
December 31, 2012, 2011 and 2010, were 146,589; 116,087; and 81,730, respectively, of Class A common stock.  There were no 
unearned ESOP shares at December 31, 2012 and 2011, 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, 2012, 2011 and 2010, new 
shares were issued to satisfy this obligation.

As of December 31, 2012, 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.    Participant 
contributions to this plan were approximately $5.1 million, $4.5 million and $4.2 million for the years ended December 31, 2012, 
2011 and 2010, respectively.

We maintained nonqualified supplemental defined benefit pension plan for certain retired employees of an acquired 
company as of December 31, 2012.  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, 2012 and 2011, 
100% of the rabbi trust assets were invested in a money market account with a commercial bank.  All covered employees retired 
prior to 1998.  Our benefit obligation at December 31, 2012 and 2011 was $1.4 million and $1.5 million, respectively.

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).  For the year ended December 31, 2011, the non-current benefit for income taxes includes $0.2 million 
for amounts arising from the exercise of stock options allocated as equity; $(0.4) 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;

The net deferred tax liabilities decreased $2.5 million in the year ended December 31, 2012 for adjustments to the purchase 
accounting related to the January 6, 2012 acquisition of Evolvent.  The net deferred tax liabilities increased $1.3 million in the 
year ended December 31, 2011 for adjustments to the purchase accounting related to the acquisitions of MTCSC on December 23, 
2010 and WINS on November 15, 2011.  

The tax benefits associated with nonqualified stock options and disqualifying dispositions of incentive stock options 
reduced the current taxes payable by $0.2 million for the year ended December 31, 2011.  These benefits were recorded as an 
increase to additional paid-in capital. 

At December 31, 2012, we had state net operating losses of approximately $0.4 million that expire beginning 2015 through 

2031; and federal net operating losses of $8.2 million that expire in 2031 and 2032.

The total liability for gross unrecognized tax benefits as of December 31, 2012, 2011 and 2010 includes $1.0 million, 
$1.1 million and $2.1 million, respectively, of unrecognized net tax benefits which, if ultimately recognized, would reduce the 
Company's 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 

66

 
to U.S., state or non-U.S. income tax examinations by tax authorities for the years before 2008.  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, 2012, 2011 and 2010, interest and penalties 
on the net unrecognized tax benefits were $0.2 million, $0.2 million and $0.4 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, state and local governments and commercial customers.  Our federal 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.    Revenues  from  the  U.S.  government  under  prime  contracts  and 
subcontracts were approximately 99.2%, 99.2% and 98.7% for the years ended December 31, 2012, 2011 and 2010, respectively.  
There were no sales to any customers within a single country (except for the United States) where the sales accounted for 10% or

14. Sale of Investment 

ManTech received approximately $3.2 million in proceeds on April 8, 2011 and $0.2 million was received during the 
year  ended  December 31,  2012  for  the  sale  of  our  investment  of  less  than  5%  in  NetWitness  Corporation  (NetWitness).   At 
December 31, 2012, there was $0.3 million held in escrow, which we expect to collect next year.  The transaction was consummated 
on April 1, 2011 pursuant to an agreement and plan of merger dated March 12, 2011 by and among EMC Corporation, NetWitness 
and certain persons acting as the representative for the shareholders of NetWitness.  The sale of our investment resulted in a pre-
tax gain of approximately $3.7 million, which was recorded in other income in our consolidated statement of income for the year 
ended December 31, 2011.

Management has evaluated subsequent events after the balance sheet date through the financial statements issuance date 

for appropriate accounting and disclosure.     

Acquisition of ALTA Systems, Inc.

On January 8, 2013, we completed the acquisition of ALTA Systems, Inc. (ALTA).  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 practice areas: capital planning and 
investment control; system design, development and operations; and fraud detection and statistical analysis.  The acquisition will 
enable ManTech to deliver technology services through ALTA's prime position on the Centers for Medicare and Medicaid Services 
(CMS) Enterprise Systems Development (ESD) contract.  ManTech funded the acquisition with cash on hand.  The preliminary 
69

 
 
purchase price was $10.2 million and may increase or decrease depending on the finalization of the post-closing working capital 
adjustment.  

Item 9. 

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

The  Company  has  had  no  disagreements  with  its  auditors  on  accounting  principles,  practices  or  financial  statement 

disclosure during and through the date of the financial statements included in this Report. 

Item 9A 

Controls and Procedures 

We performed an assessment as of December 31, 2012 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 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. 

70

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 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 Internal 
Control-Integrated Framework 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, 2012 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 Internal Control-Integrated Framework to assess the effectiveness of our internal 
control over financial reporting.  Based upon the assessments, our management has concluded that as of December 31, 2012 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, 2012, 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.

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, 2012, based on criteria established in Internal Control - Integrated Framework 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, 2012, based on the criteria established in Internal Control - Integrated Framework 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, 2012 of the Company 
and our report dated February 22, 2013 expressed an unqualified opinion on those financial statements and financial statement 
schedule.

Forward-Looking Statement

This summary annual report contains “forward-looking” statements that ManTech believes to be within the definition in the Private Securities Litigation 
Reform Act of 1995.  Such statements involve substantial risks and uncertainties, many of which are outside of our control. Words such as “may,” “will,” “expect,” 
“intend,” “anticipate,” “believe,” or “estimate,” or the negative of these terms or words of similar import are intended to identify forward-looking statements.

Although forward-looking statements in this summary annual report reflect our good-faith judgment, such statements can only be based on facts and 
factors currently known by us and are inherently subject to risks and uncertainties. Actual results and outcomes may differ materially from the results 
and outcomes we anticipate. Factors that could cause actual results to differ materially from the results we anticipate, include, but are not limited to, the 
following: adverse changes or delays in U.S. government spending for programs we support due to cost cutting and efficiency initiatives and other efforts 
to reduce federal government spending generally, uncertainty regarding the timing and nature of government action to complete the budget process 
and otherwise address budgetary constraints, sequestration, or other factors; failure to compete effectively for new contract awards or to retain existing 
U.S.  government  contracts;  failure  to  obtain  option  awards,  task  orders  or  funding  under  contracts;  delays  in  the  competitive  bidding  process  caused 
by competitors’ protests of contract awards received by us; adverse changes in our mix of contract types; renegotiation, modification or termination of 
our  contracts,  or  failure  to  perform  in  conformity  with  contract  terms  or  our  expectations;  failure  to  realize  the  full  amount  of  our  backlog  or  adverse 
changes in the timing of receipt of revenues under contracts included in backlog; failure to maintain strong relationships with other contractors; failure 
to successfully identify and execute future acquisitions; failure to successfully integrate recently acquired companies or businesses into our operations or 
to realize any accretive or synergistic effects from such acquisitions; adverse changes in business conditions that may cause our investments in recorded 
goodwill to become impaired; non-compliance with, or adverse changes in, complex U.S. government procurement laws and regulations; adverse results 
of U.S. government audits or other investigations of our government contracts; adverse changes in our financing arrangements, such as increases in interest 
rates and restrictions imposed by our outstanding indebtedness, including the ability to meet financial covenants, or inability to obtain new or additional 
financing; and disruption of our business resulting from internal systems or service failures or breaches in customer systems, including as a result of cyber 
or other security threats. These and other risk factors are more fully discussed in the section entitled “Risks Factors” in ManTech’s Annual Report on Form 10-K 
previously filed with the Securities and Exchange Commission on Feb. 22, 2013, Item 1A of Part II of our Quarterly Reports on Form 10-Q, and, from time to 
time, in ManTech’s other filings with the Securities and Exchange Commission.

We  urge  you  not  to  place  undue  reliance  on  these  forward-looking  statements,  which  speak  only  as  of  the  date  of  this  summary  annual  report. We 
undertake no obligation to update any of the forward-looking statements made herein, whether as a result of new information, subsequent events or 
circumstances, changes in expectations or otherwise.
