2019 RESULTS

In 2019, ManTech’s revenue rose 13 percent over 
the past year to $2.2 billion, our fourth consecutive 
year of strong organic growth. We reported operating 
income of $138 million and net income of $114 million.
Diluted earnings per share was $2.83. Operating
cash flow was $221 million, and the company had $9
million in cash and cash equivalents and $37 million in 
outstanding borrowings on its $500 million revolving-
credit facility.

Total contract awards reached $2.9 billion, driving a
healthy book-to-bill ratio of 1.3 and demonstrating 
strong market demand for ManTech’s expertise across 
the full span of our technology solutions. Among the 
leading awards in 2019:

• $746 million in awards by the Intelligence 

Community for enterprise IT and cyber, systems 
engineering, and intelligence lifecycle support. 

• $322 million five-year contract to provide mission
IT, systems integration, cyber operations and
analytics of geospatial intelligence for the U.S.
Marine Corps Expeditionary Operating Forces and 
the Intelligence Community.

• $279 million seven-year contract by an agency of 
the Department of Defense to provide cyber and 
enterprise IT services. 

• $176 million in contracts with the Navy and 

Marine Corps Public Health Center and Defense
Health Agency (DHA) for solutions that accelerate
healthcare delivery for active duty military,
reservists and their families.

To build on this impressive record of success, ManTech
invested in the future. Significant acquisitions
positioned the company for rapid expansion in the
fast-growing markets of healthcare IT and intelligence
support. 

ManTech International Corporation

In April we acquired Kforce Government Solutions
(KGS), a seasoned provider of transformation
management, data management and analytics in 
support of federal health and defense missions, 
notably the Department of Veterans Affairs. In August 
we acquired the H2M Group, a respected company 
in geospatial analysis, imagery and full motion video 
analysis for the Intelligence Community. These 
strategic acquisitions expanded our talent pool, 
complemented our proven technology capabilities, and 
will contribute to continued growth in these sectors in
the years ahead. 

LEADERSHIP AND RECOGNITION

ManTech places strong emphasis on leadership that 
inspires our people to deliver stellar performance, and
creates new opportunities for them to advance their 
careers. We continue to attract the best and brightest
executives to drive strategic objectives.

In May 2019, we welcomed a new member to
our Board of Directors, Peter LaMontagne, an 
accomplished private equity executive with more 
than 20 years of leadership experience at technology 
companies including ManTech that serve the U.S. 
government. We also named Daniel E. Payne as Senior 
Vice President and Chief Security Officer, in charge of 
our ManTech Secured initiative.

ManTech leadership aggressively pursued initiatives 
that inspire our people to greatness. Through our 
education partner, Purdue University Global, we
launched our bachelor of science degree program in 
analytics, the third such curriculum made available
tuition-free to eligible employees, and hailed 
graduates from our first two Purdue programs, in
cyber and cloud. We also partnered with Skillsoft 
to give all employees free access to thousands of 
courses in technology and business management.

These initiatives succeeded in attracting and 
retaining the finest talent to advance our strength in 
today’s most lucrative fields of technology. In 2019,
Washingtonian Magazine named ManTech one of the 
“50 Great Places to Work,” and Military Times ranked 
us a “Best for Vets Company.” Such distinctions led to 

Great People, Innovative Technology

the type of honor that resonates with customers, as well:
the 2019 American Security Today ‘ASTORS’ Platinum 
Homeland Security Award for ACRETM as Best Breach 
and Attack Simulation Platform in cybersecurity.

2020 VISION

ManTech has focused on and is positioned at the heart 
of core technologies and solutions supporting missions
of national significance. With the GFY20 federal budget 
in place and approved GFY21 budget levels, the federal 
market remains strong.  Our focus on national and
homeland security, as well as the security of critical
systems and data, will position ManTech for continued 
growth. We remain committed to investing in the best 
talent and enabling technologies needed to respond 
to our customers’ need for agility, speed, and security 
in the digital age.  We aim to harvest the power of 
technology to secure the future.

Our customers' successes are the end result of the hard work of our talented and dedicated employees.  At year end, our 
workforce consisted of approximately 8,900 employees, 68% of whom hold security clearances and approximately 45% of whom 
are veterans.  

Our Customers

We derive the vast majority of our revenues from U.S. government customers.  We have successful, long-standing relationships 

with these customers, having supported many of them for almost half a century. 

Backlog

At December 31, 2019, our backlog was $9.1 billion, of which $1.3 billion was funded backlog.  At December 31, 2018, our 

backlog was $8.4 billion, of which $1.3 billion was funded backlog.

We define backlog as our estimate of the remaining future revenue from existing signed contracts, assuming the exercise of 
all options relating to such contracts and including executed task orders issued under Indefinite Quantity/Indefinite Delivery (ID/
IQ) contracts.  We also include an estimate of revenue for solutions that we believe we will be asked to provide in the future under 
the terms of ID/IQ contracts for which there are established patterns of revenues.

We define funded backlog as 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.  

6

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 over a much longer period 
of time.

A variety of circumstances or events may cause changes in the amount of our backlog and funded backlog, including the 
execution of new contracts, the extension of existing contracts, the non-renewal or completion of current contracts, 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.

Seasonality

Our business is not seasonal.  However, in order to avoid the loss of unexpended fiscal year funds it is not uncommon for 
U.S. government agencies to award extra tasks or complete other contract actions in the weeks before September 30, which is the 
end of the government fiscal year.  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 revenue in the first and fourth quarters of our fiscal 
year. 

Competitive Landscape

We compete in a market shaped by customer requirements and federal budget priorities and constraints.  Our key competitors 
currently include divisions of large defense contractors, as well as a number of large and 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 we bid 
against these companies in other situations.

Item 1A. 

Risk Factors 

Set forth below are the risks that we believe are material to our investors.  You should carefully consider the following risks, 
together with the other information contained in or incorporated by reference into this Annual Report on Form 10-K, including 
our consolidated financial statements and notes thereto.  Any of the following risks could materially and adversely affect our 
business, financial condition, results of operations and prospects, as well as the actual outcome of matters as to which forward-
looking statements are made in this Annual Report.

The risks described below are not the only risks we face.  Additional risks and uncertainties not currently known to us, or 
those we currently deem to be immaterial, may also materially and adversely affect our business, financial condition or results of 
operations.    This  section  contains  forward-looking  statements.    You  should  refer  to  the  explanation  of  the  qualification  and 
limitations of forward-looking statements set forth at the beginning of this Annual Report.

Risks Related to Our Business

We depend on contracts with the U.S. government for substantially all of our revenues.  If our relationships with the U.S. 
government are harmed, our business, future revenues and growth prospects could be adversely affected.

We derive the vast majority of our revenues from U.S. government customers, and we anticipate that U.S. government contracts 
will be the primary source of our revenues for the foreseeable future. Any issue that compromises our relationship with the U.S. 
government generally, or any U.S. government agency that we serve, could adversely and materially harm our business, prospects, 
financial condition or operating results.  Among the key factors in maintaining our relationships with U.S. government agencies 
are our performance on our contracts and task orders, the strength of our professional reputation, compliance with applicable laws 
and regulations, and the strength of our relationships with our customers and client personnel. To the extent our reputation or 
relationships with U.S. government agencies is impaired, our revenue and operating profits could materially decline. 

7

  
We may fail to attract and retain skilled and qualified employees with requisite specialized skill sets or security clearances, 
which could impair our ability to effectively serve our clients, require more subcontracting work than is optimal, impact our 
profitability and limit our growth prospects.

Our business depends in large part upon our ability to attract and retain sufficient numbers of employees who have advanced 
IT and technical services skills.  Often, these employees must also have some of the highest security clearances in the United 
States. Cleared employees are in great demand (particularly as it relates to the limited supply of cleared personnel with certain IT 
and technical service skills), and we compete intensely for such qualified personnel with other U.S. government contractors, the 
U.S. government and private industry. The government and industry have recognized that the current process for obtaining security 
clearances is time-consuming, inefficient and can present a risk to customer mission. While some improvements have been made 
to the process in the last couple of years, security clearances at the highest levels may still take months or even years to complete. 
We anticipate that such personnel may remain a limited resource for the foreseeable future. If we are unable to hire a sufficient 
number of qualified employees or cannot obtain their appropriate security clearances in a timely manner, our ability to serve our 
clients could be harmed, and we may not be able to grow our business.  Additionally, if we cannot hire sufficient qualified employees 
to staff our contracts, we may be required to engage more contracted personnel, which could reduce our profit margins. Even if 
we are able to attract the requisite skilled employees, intense competition for such employees may result in attrition in our employee 
ranks, and we may need to expend additional resources to hire, train and replace such personnel.

U.S. government spending and mission priorities could change in a manner that adversely affects our future revenues and 
limits our growth prospects.

We depend on continued expenditures by the U.S. government on programs that we support.  Spending levels on programs 
that we support (including those related to intelligence, defense, homeland security, and federal health IT missions) have varied 
over time, and our customers may reduce expenditures for our services for any number of reasons, to include changing mission 
priorities, the availability of discretionary spending in light of the country’s growing debt and long-term fiscal challenges, and the 
implementation of efficiency and cost reduction efforts. A reduction in U.S. government spending levels, or changes in spending 
priorities, could adversely affect our business and impact our future revenues. 

We encounter intense competition to win contracts and most of our contracts are awarded through competitive bidding processes; 
our revenue and profitability may be adversely impacted if we fail to compete effectively for such awards, or if there are delays 
as a result of our competitors' protests of contract awards that we receive.

We operate in a highly competitive industry, with contract awards typically subject to competitive bidding processes. We may 
not be able to continue to win competitively awarded contracts at historic levels. We compete with larger companies who have 
significant financial resources, as well as smaller, more specialized companies that may be able to concentrate their resources into 
highly-skilled niche markets. Our competitors may be able to provide our customers with more desirable capabilities or better 
contract terms than we can provide, including price, technical qualifications, past contract experience, geographic presence and 
the availability of qualified professional personnel.  

Our failure to compete effectively in competitive procurements could adversely impact our future revenues. Participating in 
the competitive bidding process also involves costs, risks and uncertainties, including the cost, time and effort required to prepare 
bids  and  proposals  for  contracts  that  may  not  ultimately  be  awarded  to  us;  the  need  to  expend  resources  or  make  financial 
commitments (such as procuring leased premises) in advance of an award decision, or the need to bid on programs prior to the 
completion of their design, which may result in execution challenges, cost overruns, or in the case of unsuccessful competitions, 
the loss of committed costs; and the ability to accurately estimate the resources and costs structure required to service any contract 
we are awarded. The loss of business to our competitors could adversely impact our revenues and, if we are forced to reduce our 
prices, adversely impact our profitability.

In recent years, the competitive environment has also resulted in an increase in bid protests from unsuccessful bidders on 
contract awards. It can take months to resolve protests by one or more of our competitors relating to contracts that are awarded 
to us. Even where the protest is unsuccessful and the award to us is upheld, the resulting delay in startup and funding of the work 
under such contracts may adversely impact our revenues and profitability. 

Cyber attacks and other security threats could disrupt our business and impair our ability to effectively provide services to our 
customers; as a leading provider of cyber security services to our customers, any significant cyber incident could damage our 
reputation and have a material adverse effect on our business and financial results. 

We create, implement and maintain IT and engineering systems, and provide services that are often critical to our customers' 

8

operations, some of which involve classified or other sensitive information in intelligence, national security and other classified 
or sensitive customer functions. Our network and systems are subject to continuous exposure to cyber and other security threats, 
including computer viruses, attacks by individual and state-sponsored computer hackers and physical break-ins. We also face a 
heightened risk of a security breach or disruption due to our custody of classified and other sensitive information. We, like other 
government contractors, are regularly the target of cyber incidents, and these attempted cyber intrusions are expected to continue 
to proliferate. 

If we are unable to protect our network and systems from significant cyber attacks, or if we are unable to detect intrusion 
attempts  or  other  cyber  incidents  quickly  and  remediate  those  incidents  successfully,  we  may  experience  one  or  more  of  the 
following adverse effects:

• 
• 

• 
• 

• 

loss of revenue due to adverse customer reaction;
exposure to claims for damages, or the incurrence of significant costs related to upgrading systems, networks and 
our cyber security program generally;
loss of revenue due to the redeployment of staff for remediation efforts instead of work on billable contracts;
damage to our reputation, which could adversely impact our ability to attract or retain customers or market our 
services that relate to the creation or maintenance of secure IT systems; and
be unable to successfully market services that rely on the creation and maintenance of secure IT systems.

While we maintain cyber risk insurance to provide some coverage for certain risks arising from cybersecurity breaches, there 
is  no  assurance  that  such  insurance  would  cover  all  or  a  significant  portion  of  the  costs  or  consequences  associated  with  a 
cybersecurity breach.  In addition to these costs and the adverse effects described in this risk factor, a significant cyber breach 
could result in one or more of our customers terminating or reducing the scope of our contracts with them.

Security breaches in customer systems could adversely affect our business.

Many  of  the  programs  we  support  and  the  systems  we  develop,  install  and  maintain  involve  managing  and  protecting 
information involved in intelligence, national security and other classified or sensitive customer functions.  Losses from a security 
breach in one of these systems could cause serious harm to our business, damage our reputation and impact our eligibility for 
further work on critical systems for our current customers or for other U.S. government customers generally.  Losses could also 
exceed the policy limits of our errors and omissions and product liability insurance coverage.  If our reputation is damaged or our 
eligibility to compete for additional work is compromised our revenues could be adversely affected.

Congress may fail to approve budgets on a timely basis for the federal agencies we support which 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 government fiscal year on September 30, Congress 
typically funds government operations pursuant to a continuing resolution, which allows federal government agencies to operate 
at spending levels approved in the previous budget cycle. When the government operates under a continuing resolution, funding 
we expect to receive from customers for current work may be delayed and new initiatives may be delayed or even canceled. The 
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. A  prolonged  delay  in  Congressional  budget  approval  could  delay  our  customers’ 
procurement of our services and adversely impact our business and results of operations.

Our earnings and profitability may vary based on the mix of our contracts, and may be adversely affected if we fail to accurately 
estimate and manage our costs, time and resources.

We generate revenues under different types of government contracts, including cost-reimbursable, time-and-materials and 
fixed-price contracts. Our earnings and profitability may vary depending on changes in the amount of revenues we derive from 
each type of contract, the nature of services or solutions provided, or the level of achievement of performance objectives required 
to  receive  award  fees.  For  example,  cost-reimbursable  contracts  generally  offer  lower  margin  opportunities  than  fixed-price 
contracts, but tend to minimize financial risk. However, to varying degrees, each contract type involves some risk of underestimating 
the costs and resources necessary to fulfill the contract obligations. Our profitability is adversely impacted when we incur contract 
costs that we cannot bill to our customers. While fixed-price contracts allow us to benefit from cost savings, these contracts also 
increase our exposure to the risk of cost overruns. When bidding on proposals involving fixed-price contracts, we rely heavily on 
our estimates of costs and the time required to complete the associated projects and make assumptions regarding technical issues. 
Our failure to accurately estimate these costs or the resources and technology necessary to perform these contracts, or to effectively 
manage and control our costs during performance of work could result, and in some instances has resulted, in reduced profits or 
9

in losses. More generally, any increased or unexpected costs or unanticipated delays in connection with performing our contracts 
(including costs and delays caused by factors outside of our control) could make our contracts less profitable than expected.

U.S. government contracts contain provisions giving our customers a variety of rights that are unfavorable to us, including 
the ability to terminate a contract at any time for convenience.

U.S. government contracts contain provisions and are subject to laws and regulations that provide the government with rights 
and remedies not typically found in commercial contracts. Among other rights, these contracts give the government the ability to:

• 
• 
• 
• 
• 
• 
• 

terminate existing contracts for convenience, as well as for default;
reduce orders under, or otherwise modify, contracts or subcontracts;
decline to exercise an option to renew multi-year contracts or issue task orders under multiple award contracts;
suspend or debar us from doing business with the U.S. government or with a government agency;
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 are subject to complex laws and regulations, and if we fail to comply with these laws and regulations, we could be subject 
to severe penalties and sanctions and harm our business.

As a government contractor, we are subject to numerous laws and regulations that govern how we conduct business with our 

customers. The following are among the more noteworthy laws and regulations:

• 

the  Federal  Acquisition  Regulation  and  the  Defense  Federal  Acquisition  Regulation  Supplement,  which 
comprehensively regulate the formation, administration and performance of U.S. government contracts; 

•  Truthful Cost or Pricing Data, 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-reimbursable U.S. government contracts;
laws, regulations and executive orders restricting the use and dissemination of information classified for national 
security purposes and the export of certain products, services and technical data;

•  U.S. export controls, which apply when we engage in international work; 
• 
• 

the Foreign Corrupt Practices Act; and 
the False Claims Act, which prohibits the submission of fraudulent claims to the government for payment or 
approval. Actions under the False Claims Act may be brought by either the government or by individuals 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 be subject to contractual damages, fines, civil or criminal penalties 
or administrative sanctions, and could harm our reputation. For more severe misconduct, sanctions and penalties may include the 
termination of contracts, forfeiture of profits, the triggering of price reduction clauses, suspension of payments, fines and the 
suspension or debarment from doing business with federal government agencies, any of which could adversely affect our business, 
financial condition, operating results and future prospects.

Unfavorable  results  of  U.S.  government  audits  or  other  investigations  could  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),  Defense  Contract  Management Agency  (DCMA)  and  other  government 
agencies  routinely  audit  and  investigate  government  contracts  and  contractor  systems.  These  agencies  review  our  contract 
performance, cost structure and compliance with applicable laws, regulations and standards. The DCAA and DCMA also review 
the  adequacy  of,  and  compliance  with,  internal  control  systems  and  policies,  including  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, 
10

while such costs already reimbursed must be refunded. If our internal control systems or policies are found to be non-compliant 
or inadequate, payments may be withheld or suspended, or we may be subject to increased government scrutiny and approval 
requirements that could delay or adversely affect our ability to invoice and receive timely payment for services we perform on 
our contracts.  Adverse findings by DCAA or DCMA may also impair our ability to compete for and win new contracts with the 
U.S. government.  

We  may  acquire  businesses,  and  these  transactions  involve  numerous  risks  and  uncertainties  that  could  adversely  impact 
ongoing operations.

As part of our operating strategy, we selectively pursue acquisitions. These transactions pose many risks, including:

• 
• 

• 
• 
• 
• 

our inability to identify suitable acquisition candidates at prices we consider attractive;
our inability to compete successfully for an identified acquisition candidate, consummate an acquisition or accurately 
estimate the financial effect of acquisitions on our business;
difficulty retaining an acquired company's key employees, customers or contracts;
difficulty integrating acquired businesses, resulting in unforeseen difficulties and greater expense than anticipated;
our failure to discover or adequately assess liabilities of a business that we acquire; and 
the need to record write-downs from future impairments of intangible assets, which could reduce our future reported 
earnings.

Acquired entities may not achieve to the level of profitability or revenue that we anticipate. Additionally, we may not realize 

anticipated synergies. If our acquisitions perform poorly, our business and financial results could be adversely affected.

We face risks associated with our international business, and our business operations in foreign countries involve considerable 
risks and hazards.  

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; business practices and customs that are unfamiliar or inconsistent with business practices in the U.S.; requirements 
to provide up-front performance bonds (guaranteed by a letter of credit from our lender); difficulties in collecting receivables and 
the lack of legal remedies in the event of contract disputes; adverse tax treatment; and additional compliance requirements relating 
to international and U.S. laws.

We also provide services to the U.S. government in foreign countries that may be experiencing political unrest, war or terrorism. 
In connection with these deployments, we may be exposed to increased risk of incurring liabilities arising from incidents involving 
our employees or third parties. We may also incur additional costs in connection with such deployments, such as increased insurance 
costs, the cost of liabilities that are in excess of or not covered by our insurance policies, or the costs of repatriation of our employees 
or executives for reasons beyond our control.

Goodwill represents a significant asset on our balance sheet, and changes in future business conditions could cause these 
investments to become impaired, requiring substantial write-downs that would reduce our operating income.

As of December 31, 2019, our goodwill was $1.2 billion.  The amount of our recorded goodwill may substantially increase 
in the future as a result of any acquisitions that we make.  We evaluate the recoverability of recorded goodwill amounts annually, 
or when evidence of potential impairment exists.  Impairment analysis is based on several factors requiring judgment and the use 
of estimates, which are inherently uncertain and based on assumptions that may prove to be inaccurate.  Additionally, material 
changes in our financial outlook, as well as events outside of our control, such as deteriorating market conditions for companies 
in our industry, may indicate a potential impairment.  When there is an impairment, we are required to write down the recorded 
amount of goodwill, which is reflected as a charge against operating income.

Covenants in the instruments governing our revolving credit facility may restrict our financial and operating flexibility.

We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as administrative agent.  The credit 
agreement provides for a $500 million revolving credit facility.  The maturity date for the credit agreement is August 17, 2022.  
The credit agreement requires us to comply with specified financial covenants, including the maintenance of certain consolidated 
total leverage ratios and a certain fixed charge coverage ratio, and contains negative covenants that, among other things, may limit 
or impose restrictions on the ability of us to incur additional indebtedness, make investments, make acquisitions and undertake 
certain other actions.  Additionally, an event of default under the credit agreement could result in our creditors exercising rights 
that could have a material adverse effect on our business.

11

Changes in tax law could adversely impact our results of operations. 

We are subject to taxation in the U.S. and certain other foreign jurisdictions. Any future changes in applicable federal, state 
and local, or foreign tax laws and regulations or their interpretation or application, including those that could have a retroactive 
effect, could result in us incurring additional tax liabilities in the future. Any final determination of tax audits or related litigation 
may be materially different than our current provisional amounts, which could materially affect our tax obligations and effective 
tax rate. 

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.  In addition to the risk factors 
already identified in this section of our Form 10-K, a number of additional factors could cause our revenues, cash flows and 
operating results to vary from quarter-to-quarter, including:

• 
• 
• 
• 

fluctuations in revenues earned on fixed-price contracts and contracts with a performance-based fee structure;
timing of significant bid and proposal costs;
seasonal or quarterly fluctuations in our workdays and staff utilization rates; and
changes in the volume of purchase requests from customers for equipment and materials.

Because most of our expenses are fixed, cash flows from our operations may vary significantly as a result of changes in the 
level  of  services  we  provide  under  existing  contracts,  as  well  as  the  number  of  contracts  that  are  commenced,  completed  or 
terminated during any quarter. Depending on the nature of the contract, we may incur significant operating expenses during the 
start-up and early stages of large contracts and not receive corresponding payments from the customer 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.

We have maintained a regular cash dividend program since 2011. We anticipate continuing to pay quarterly dividends during 
2020. However, any future payment of dividends, including the timing and amount of any such dividends, is at the discretion of 
our Board of Directors and may depend upon our earnings, liquidity, financial condition, alternate capital deployment opportunities 
or any other factors that our Board considers relevant. A change in our regular cash dividend program could have an adverse effect 
on the market price of our common stock.

Mr. Pedersen, our Executive Chairman and Chairman of the Board, effectively controls us, and his interests may not be aligned 
with those of other stockholders.

As of December 31, 2019, Mr. Pedersen owned approximately 33% 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. As of December 31, 2019, Mr. Pedersen beneficially owned 13,187,195 shares of Class B common and controlled 
approximately 83% of the combined voting power of our stock. Accordingly, Mr. Pedersen controls the vote on substantially 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 us, regardless of whether a premium is offered over then-current market prices. Mr. Pedersen will also be 
able to cause a change of control of us. 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 adversely affect the trading 
price of our stock.

12

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 us, 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 our Board to issue preferred stock; the inability of stockholders to take action by written consent; 
and advance notice requirements relating to director nominations or other proposals submitted by our stockholders.

Item 1B. 

Unresolved Securities and Exchange Commission 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 do not own any facilities or real estate that are material to our operations. 

Item 3. 

Legal Proceedings 

We are subject to certain legal proceedings, government audits, investigations, claims and disputes that arise in the ordinary 
course of our business.  Like most large government defense contractors, our contract costs are audited and reviewed on a continual 
basis by an in-house staff of auditors from the DCAA.  In addition to these routine audits, we are subject from time-to-time to 
audits and investigations by other agencies of the U.S. government.  These audits and investigations are conducted to determine 
if our performance and administration of our government contracts are compliant with contractual requirements and applicable 
federal statutes and regulations.  An audit or investigation may result in a finding that our performance, systems and administration 
are  compliant  or,  alternatively,  may  result  in  the  government  initiating  proceedings  against  us  or  our  employees,  including 
administrative  proceedings  seeking  repayment  of  monies,  suspension  and/or  debarment  from  doing  business  with  the  U.S. 
government or a particular agency or civil or criminal proceedings seeking penalties and/or fines.  Audits and investigations 
conducted by the U.S. government frequently span several years. 

Although we cannot predict the outcome of these and other legal proceedings, investigations, claims and disputes, based on 
the information now available to us, we do not believe the ultimate resolution of these matters, either individually or in the aggregate, 
will have a material adverse effect on our business, prospects, financial condition or operating results.

PART II

Item 5. 

Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information 

Our Class A common stock has been quoted on the Nasdaq Stock Market under the symbol “MANT” since our initial public 
offering on February 7, 2002.  There is no established public market for our Class B common stock.  As of February 19, 2020, 
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 years 2019 and 2018, we declared and paid quarterly dividends, each in the amount of $0.27 and $0.25 per 
share, respectively, on all issued and outstanding shares of common stock.  For 2020, we anticipate we will continue paying 
quarterly dividends, and on February 19, 2020, the Board of Directors declared a quarterly cash dividend in the amount of $0.32
per share; however any future dividends declared will be at the discretion of our Board of Directors and will depend, among other 
factors, upon our earnings, liquidity, financial condition, alternate capital allocation opportunities or any other factors our Board 
of Directors deems relevant. 

Recent Sales of Unregistered Securities 

We did not issue or sell any securities in fiscal year 2019 that were not registered under the Securities Act of 1933. 

Equity Compensation Plan Information 

Information regarding our equity compensation plans and the securities authorized for issuance thereunder is incorporated 
by reference in Item 12 “Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.” 

Purchase of Equity Securities

We did not purchase equity securities during the year ended December 31, 2019.

(1) On January 1, 2019, we adopted Accounting Standards Codification (ASC) 842, Leases, using the modified retrospective 
method at the beginning of the period of adoption, January 1, 2019, through the recognition of a lease obligation and 
corresponding right of use asset.  Results for reporting periods beginning after January 1, 2019 are presented under ASC 842, 
while prior periods amount were not adjusted and continue to be reported in accordance with ASC 840, Leases. 

(2) On January 1, 2018, we adopted ASC 606, Revenue from Contracts with Customers, using the modified retrospective 
method applied to those contracts that were not substantially complete as of January 1, 2018.  Results for reporting periods 
beginning after January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to 
be reported in accordance with ASC 605, Revenue Recognition.

(3) The Tax Cuts and Jobs Act, enacted on December 22, 2017, reduces the U.S. corporate tax rate from 35% to 21%
beginning in 2018.  Due to the enactment of the Tax Cuts and Jobs Act, our income tax expense was reduced by $50.6 million
for the year ended December 31, 2017 from the re-measurement of our existing deferred tax assets and liabilities.

(4) Over the past five years, we completed 7 acquisitions.  In aggregate, these acquisitions have added $343.6 million in
goodwill.  For additional information on our recent acquisitions, see Note 5 to our consolidated financial statements in Item 8.

Item 7. 

Management's Discussion and Analysis of Financial Condition and Results of Operations 

The following discussion of our financial condition and results of operations should be read together with the consolidated 
financial statements and the notes to those statements included in Item 8 “Financial Statements and Supplementary Data."  This 
discussion contains forward-looking statements that involve risks and uncertainties.  For a description of these forward-looking 
statements, refer to Part I “Cautionary Note Regarding 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 those discussed elsewhere in this Annual Report.

Overview 

We provide mission-focused technology solutions and services for U.S. defense, intelligence community and federal civilian 
agencies.  We excel in full-spectrum cyber, data collection & analytics, enterprise IT, systems and software engineering solutions 
that support national and homeland security. 

16

Approximately 98% of our revenues during the year ended December 31, 2019 were generated from contracts with the U.S. 
government, or through prime contractors supporting the U.S. government.  The U.S. government is the largest consumer of 
services and solutions in the U.S.  In government fiscal year (GFY) 2019, the U.S. government obligated approximately $355 
billion on contracted services, a 6% increase from the prior year.  Our business is impacted by the overall U.S. government budget 
and the alignment of our capabilities and offerings with the U.S. government's spending priorities.  The Department of Defense 
(DoD) is the largest purchaser of services and solutions in the U.S. government.  Federal spending, particularly the DoD, has 
experienced six years of consecutive growth.  In July 2019, Congress passed, and the President signed, legislation that increased 
budgetary control caps for GFY 2020 and GFY 2021 above limits previously set by the Budget Control Act of 2011, effectively 
ending the possibility of sequestration.  The legislation also included an extension of the federal debt limit to July 2021.  In 
December 2019, Congress passed and the President signed into law, two appropriation bills funding the government through GFY 
2020.  The appropriations bill contained $705 billion excluding emergency funding in GFY 2020 for defense.  The continued 
budget clarity over the last few years has resulted in our customers making more award decisions and procuring services to meet 
mission needs on a more regular and predictable basis.  We believe the current appropriations and the Administration's stated 
priorities for national and homeland security aligns favorably with our capabilities and offerings. 

We continually monitor U.S. government spending and budgetary priorities to align our investments in new capabilities to 
drive organic growth.  We will selectively pursue acquisitions that broaden our domain expertise and service offerings and/or 
establish relationships with new customers.  In 2019 we acquired Kforce Government Solutions (KGS), a provider of services, 
IT solutions, transformation and management consulting and data analytics - most notably in the healthcare IT market.  During 
2019, we also acquired H2M Group (H2M), a provider of intelligence and analysis services and solutions primarily to the National 
Geospatial-Intelligence Agency.  Since going public in 2002, we have acquired and integrated 30 businesses into our operations.    

Our industry remains competitive on price.  While there has been a trend away from the lowest-price technically acceptable 
procurement model for a majority of our customers, contracts continue to be awarded through a competitive bidding process 
(including indefinite delivery, indefinite quantity and other multi-award contracts), which could increase pricing pressure.  To 
ensure our cost structure remains competitive, we continually evaluate and adjust our levels of indirect spending to stay in line 
with the expected business opportunities.  Our industry also remains competitive with respect to attracting and retaining employees 
with the necessary skills and security clearances to perform certain services that are a priority for our customers.  

We classify indirect costs incurred as cost of services and general and administrative expenses in the same manner as such 
costs are defined in our disclosure statements under the government's Cost Accounting Standards.  Effective January 1, 2019, we 
updated our disclosure statements with the DCMA, resulting in certain costs being classified differently either as cost of services 
or as general and administrative expenses on a prospective basis.  This change has caused a net increase in the reported cost of 
services and a net decrease in reported general and administrative expenses in 2019 as compared to 2018; however, total operating 
costs were not affected by this change.

Revenues

Substantially all of our revenues are derived from services and solutions provided to the U.S. government or to prime contractors 
supporting the U.S. government, including services provided by our employees and our subcontractors, and solutions that include 
third-party hardware and software that we purchase and integrate as a part of our overall solutions.  Customer requirements may 
vary from period-to-period depending on specific contract and customer requirements. 

We provide our services and solutions under three types of contracts: cost-reimbursable; time-and-materials; and fixed-price.  
In general, cost-reimbursable contracts are the least profitable of our government contracts but offer the lowest risk of loss.  Under 
time-and-materials contracts, to the extent that our actual labor costs are higher or lower than the billing rates under the contract, 
our profit under the contract may either be greater or less than we anticipated or we may suffer a loss under the contract.  In general, 
we realize a higher profit margin on work performed under time-and-materials contracts than cost-reimbursable contracts.  Fixed-
price contracts generally offer higher profit margin opportunities but can involve greater financial risk because we bear the impact 
of cost overruns in return for the full benefit of any cost savings.  

Cost of Services 

Cost of services primarily includes direct costs incurred to provide services and solutions to our 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.  

17

Changes in the mix of services and equipment provided under our contracts can result in variability in the proportion that cost 
of services bears to revenues.  As we typically earn higher profits on our own labor services, we expect the ratio of cost of services 
as a percentage 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 increases relative to our own labor services, 
we expect the ratio of cost of services as a percentage of revenues to increase.  

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 business 
development, bid and proposal, contracts administration, finance and accounting, legal, corporate governance and executive and 
senior management.  In addition, we included stock-based compensation, as well as depreciation and amortization expenses related 
to the general and administrative function.  Depreciation and amortization expenses include the depreciation of computers, furniture 
and  other  equipment,  the  amortization  of  third-party  software  used  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 on our debt 

and deferred financing charges. 

Interest Income

Interest income is primarily from cash on hand and late invoice payments by the government.

Revenues

The primary driver of our increase in revenues relates to revenues from new contract awards, growth on existing contracts 
and the acquisitions we completed during the year.  These increases were offset by contracts and tasks that ended during the year 
and reduced scope of work on some contracts including contracts with variable material purchase requirements.  We expect revenues 
to increase in 2020 due to recent and future new contract awards and growth on existing programs.

Cost of services 

The increase in cost of services was primarily due to increases in revenues.  As a percentage of revenues, direct labor costs 
remained stable at 47% for the years ended December 31, 2019 and 2018.  As a percentage of revenues, other direct costs, which 
include subcontractors and third party equipment and materials used in the performance of our contracts, also remained stable at 
39% for the years ended December 31, 2019 and 2018.  In 2020, we expect cost of services as a percentage of revenues to be 
comparable to 2019.

General and administrative expenses 

The increase in general and administrative expenses was primarily due to increases to support the growth of our business, 
infrastructure improvements, bad debt expense and legal matters.  These increases were partially offset by lower amortization on 
acquired intangibles and the reclassification of certain allocable expenses from general and administrative expenses to cost of 
services related to a change in disclosed cost accounting practices with the Defense Contract Management Agency.  As a percentage 
of revenues, general and administrative expenses increased for the year ended December 31, 2019 as compared to the same period 
in 2018.  In 2020, we expect general and administrative expenses as a percentage of revenues to be comparable to 2019. 

Provision for income taxes

Our effective tax rate is affected by recurring items, such as the relative amount of income we earn in various taxing jurisdictions 
and their tax rates.  It is also affected by discrete items that may occur in any given year, but are not consistent from year-to-year.  
Our effective income tax rate was 16% and 26% for the years ended December 31, 2019 and 2018, respectively.  The reduction 
in our effective tax rate is due to an increase in research and development credits we claimed on previously filed tax returns and 
will be claimed on our 2019 tax return.  The increase in research and development credits is the result of a project we completed 
during the fourth quarter of 2019 to improve the method by which we identify expenditures that qualify for the research and 
development tax credit.  We recognized $9.4 million in research and development credits related to tax years 2015-2018 and $2.5 
million related to the 2019 tax year.  While we expect this method to provide continued benefits in 2020, we expect our effective 
tax rate to increase in relation to 2019 due to the research and development credits to be recognized being limited to a single tax 
year.  For additional information concerning the research and development tax credit, see Note 13 to our consolidated financial 
statements in Item 8. 

Year Ended December 31, 2018 Compared to Year Ended December 31, 2017 

To review the comparison of our results of operations for the fiscal year ended December 31, 2018 with our results of operations 
for the fiscal year ended December 31, 2017, please refer to the section titled “Management’s Discussion and Analysis of Financial 
Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

Backlog 

For the years ended December 31, 2019 and 2018 our backlog was $9.1 billion and $8.4 billion, respectively, of which $1.3 
billion and $1.3 billion , respectively, was funded backlog.  The increase in our backlog is due to our receipt of new contract awards 
and our acquisitions.  We believe our backlog, together with new contract awards, will support continued growth in our business.  
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, 2019, our cash and cash equivalents balance was $8.9 million.  There were $36.5 million in outstanding 

19

borrowings under our revolving credit facility at December 31, 2019.  At December 31, 2019, we were contingently liable under 
letters of credit totaling $5.8 million, which reduced our ability to borrow under our revolving credit facility by that amount.  The 
maximum available borrowings under our revolving credit facility at December 31, 2019 were $457.7 million.

Generally, cash provided by operating activities is adequate to fund our operations, including payments under our regular 
cash dividend program.  Due to short-term fluctuations in our cash flows and level of operations, it may become necessary from 
time-to-time to increase borrowings under our revolving credit facility to meet cash demands.  

Cash Flows from Operating Activities 

Our operating cash flow is primarily affected by our ability to invoice and collect from our clients in a timely manner, our 
ability to manage our vendor payments and the overall profitability of our contracts.  We bill most of our customers monthly after 
services are rendered.  Our accounts receivable days sales outstanding (DSO) were 59 and 73 for the quarters ended December 31, 
2019 and 2018, respectively.  For the years ended December 31, 2019 and 2018, our net cash flows from operating activities were 
$221.4 million and $93.4 million, respectively.  The increase in net cash flows from operating activities during the year ended 
December 31, 2019 when compared to the same period in 2018 was primarily due to timing of receivable collections and an 
increase in operating income.

Cash Used in Investing Activities

Our cash used in investing activities consists primarily of business combinations, purchases of property and equipment and 
investments in capitalized software for internal use.  For the years ended December 31, 2019 and 2018, our net cash used in 
investing activities were $214.9 million and $44.3 million, respectively.  For the year ended December 31, 2019, our net cash used 
in investing activities were primarily due to the acquisitions of Kforce Government Solutions and H2M Group and the purchase 
of equipment to support managed IT service contracts, infrastructure and capitalized software for internal use.  For the year ended 
December 31, 2018, our net cash used in investing activities were primarily due to capital expenditures.

Cash Flows Used in Financing Activities 

For the years ended December 31, 2019 and 2018, our net cash used in financing activities were $2.9 million and $53.3 
million, respectively.  For the year ended December 31, 2019, our net cash used in financing activities were primarily due to 
dividends paid, offset by net borrowings under our revolving credit facility to fund our acquisitions this year and proceeds from 
the exercise of stock options.  For the year ended December 31, 2018, our net cash used in financing activities were primarily due 
to repayment of borrowings and payments of dividends, which were partially offset by proceeds from the exercise of stock options.

Revolving Credit Facility 

We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as sole administrative agent.  The 
credit agreement provides for a $500 million revolving credit facility, with a $75 million letter of credit sublimit and a $30 million
swing line loan sublimit.  The credit agreement also includes an accordion feature that permits us to arrange with the lenders for 
the provision of additional commitments.  The maturity date is August 17, 2022. 

Borrowings under our credit agreement are collateralized by substantially all the assets of us and our Material Subsidiaries 
(as defined in the credit agreement) and bear interest at one of the following variable rates as selected by us at the time of borrowing: 
a London Interbank Offer Rate (LIBOR) based rate plus market spreads (1.25% to 2.25% based on our consolidated total leverage 
ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on our consolidated total leverage ratio). 

The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain 
conditions.  The credit agreement requires us to comply with specified financial covenants, including the maintenance of certain 
consolidated leverage ratios and a certain consolidated coverage ratio.  The credit agreement also contains various covenants, 
including affirmative covenants with respect to certain reporting requirements and maintaining certain business activities, and 
negative  covenants  that,  among  other  things,  may  limit  or  impose  restrictions  on  our  ability  to  incur  liens,  incur  additional 
indebtedness, make investments, make acquisitions and undertake certain other actions.  As of, and during the fiscal years ending 
December 31, 2019 and 2018, we were in compliance with our financial covenants under the credit agreement.  

There  was  $36.5  million  and  $7.5  million  outstanding  on  our  revolving  credit  facility  at  December 31,  2019  and  2018, 

respectively. 

20

Capital Resources

We believe the capital resources available to us from cash on hand, our remaining 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.  We anticipate 
financing our external growth from acquisitions and our longer-term internal growth through one or more of the following sources: 
cash from operations; use of our revolving credit facility; and additional borrowings of debt or issuance of equity.  

Cash Management

To the extent possible, we invest our available cash in short-term, investment grade securities in accordance with our investment 
policy.  Under our investment policy, we manage our investments in accordance with the priorities of maintaining the safety of 
our principal, maintaining the liquidity of our investments, maximizing the yield on our investments and investing our cash to the 
fullest extent possible.  Our investment policy provides that no investment security can have a final maturity that exceeds six 
months and that the weighted average maturity of the portfolio cannot exceed 60 days.  Cash and cash equivalents include cash 
on hand, amounts due from banks and short-term investments with maturity dates of three months or less at the date of purchase.

Dividend

During the years ended December 31, 2019 and 2018, we declared and paid quarterly dividends in the amount of $0.27 and 
$0.25 per share on both classes of common stock.  On February 19, 2020, we declared a quarterly cash dividend in the amount of 
$0.32 per share, to be paid on March 20, 2020.  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 of Directors deems relevant. 

Off-Balance Sheet Arrangements 

In the ordinary course of business, we use letters of credit to satisfy certain contractual terms with our customers.  As of 
December 31, 2019, $5.8 million in letters of credit were issued but undrawn.  We have an outstanding performance bond in 
connection with a contract between ManTech MENA, LLC and Jadwalean International Operations and Management Company 
to fulfill technical support requirements for the Royal Saudi Air Force.  This performance bond is guaranteed by a letter of credit 
in the amount of $5.7 million. 

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 U.S. 
generally accepted accounting principles (GAAP).  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 account for a contract when both we and the customer approve and commit; our rights and those of the customer are 
identified, payment terms are identified; the contract has commercial substance; and collectability of consideration is probable.  
At contract inception, we identify the distinct goods or services promised in the contract, referred to as performance obligations. 
Then we determine the transaction price for the contract; the consideration to which we can expect in exchange for the promised 
goods or services in the contract.  The transaction price can be a fixed or variable amount.  It is common for our contracts to contain 
award fees, incentive fees or other provisions that can either increase or decrease the transaction price.  These variable amounts 
generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based 
upon customer discretion.  We estimate variable consideration at the most likely amount to which we expect to be entitled.  We 
include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue 
recognized will not occur when the uncertainty associated with the variable consideration is resolved.  Our estimates of variable 
consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment 
of our anticipated performance and historical, current and forecasted information that is reasonably available to us.  The transaction 
price is allocated to each distinct performance obligation using our best estimate of the standalone selling price for each distinct 
good or service promised in the contract.  The primary method used to estimate standalone selling price is the expected cost plus 
21

a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate 
margin for that distinct good or service promised.  Revenue is recognized when, or as, the performance obligation is satisfied.

We recognize revenue over time when there is a continuous transfer of control to our customer.  For our U.S. government 
contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the U.S. government 
to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any 
work in process.  When control is transferred over time, revenue is recognized based on the extent of progress towards completion 
of the performance obligation.  Based on the nature of the products and services provided in the contract, we use our judgment to 
determine if an input measure or output measure best depicts the transfer of control over time.  For services contracts, we typically 
satisfy our performance obligations as services are rendered.  We typically use a cost-based input method to measure progress.  
Contract costs include labor, material and allocable indirect expenses.  Revenue is recognized proportionally as contract costs are 
incurred plus estimated fees.  For time-and-material contracts, we bill the customer per labor hour and per material, and revenue 
is recognized in the amount invoiced since the amount corresponds directly to the value of our performance to date.  For stand-
ready service contracts, a time-elapsed output method is used to measure progress, and revenue is recognized straight-line over 
the term of the contract.  If a contract does not meet the criteria for recognizing revenue over time, we recognize revenue at a point 
in time.  Revenue is recognized at the point in time when control of the good or service is transferred to our customer.  We consider 
control to transfer when we have a present right to payment and our customer has legal title.  Determining a measure of progress 
and when control transfers requires us to make judgments that affect the timing of when revenue is recognized.  Essentially all of 
our contracts satisfy their performance obligations over time.

Contracts are often modified to account for changes in contract specifications and requirements.  Contract modifications 
impact the contact when the modification either creates a new performance obligation or changes the existing enforceable rights 
and obligations. The effect of a contract modification on the transaction price and our measure of progress for the performance 
obligation to which it relates is recognized as a cumulative adjustment to revenue and profit.  Furthermore, a significant change 
in one or more estimates could affect the profitability of our contracts.  We recognize adjustments in estimated profit on contracts 
in the period identified.  The impact of adjustments in contract estimates can be reflected in either revenue or operating expenses 
on our consolidated statement of income. 

We have an Estimate at Completion process in which management reviews the progress and execution of our performance 
obligations.  As part of this process, management reviews information including, but not limited to, any outstanding key contract 
matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes 
in estimates of revenue and costs.  The risks and opportunities include management’s judgment about the ability and cost to achieve 
the contract milestones and other technical contract requirements.  Management must make assumptions and estimates regarding 
labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to 
complete the performance obligation, execution by our subcontractors, the availability and timing of funding from our customer 
and overhead cost rates, among other variables.  A significant change in one or more of these estimates could affect the profitability 
of our contracts. 

Results for periods prior to January 1, 2018 were reported in accordance with ASC 605.  Revenue for cost-reimbursable 
contracts were recorded as reimbursable costs were incurred, including an estimated share of the applicable contractual fees earned.  
For performance-based fees under cost-reimbursable contracts, we recognized the relevant portion of the expected fee to be awarded 
by  the  customer  at  the  time  such  fee  can  be  reasonably  estimated,  based  on  factors  such  as  our  prior  award  experience  and 
communications with the customer regarding performance, or upon approval by the customer.  For time-and-materials contracts, 
revenue was recognized to the extent of billable rates times hours delivered plus materials and other reimbursable costs incurred.  
For long-term fixed-price contracts, revenue was recognized at a rate per unit as the units were delivered or by other methods to 
measure services provided.  Revenue from other long-term fixed-price contracts were recognized ratably over the contract period 
or by other appropriate methods to measure services provided.  Contract costs were 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, Revenue 
Recognition - Construction-Type and Production-Type Contracts, we applied the percentage of completion method.  Under the 
percentage of completion method, income was 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 required estimating the total revenue and total 
contract cost at completion of the contract.  These estimates were periodically reviewed and revisions were made as required using 
the cumulative catch-up method.  The impact on revenue and contract profit as a result of these revisions was included in the 
periods in which the revisions were made.  Estimated losses on contracts at completion were recognized when identified. In certain 
circumstances, revenue was recognized when contract amendments were not finalized. 

Accounting for Business Combinations, Goodwill and Other Intangible Assets

The purchase price of an acquired business is allocated to the tangible assets, financial assets and separately recognized 

22

 
 
intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as goodwill.  
Determining the fair value of assets acquired and liabilities assumed requires significant judgment, which includes, among other 
factors, analysis of historical performance and estimates of future performance.  These factors may cause final amounts to differ 
materially from original estimates. In some cases, we use discounted cash flow analyses, which are based on our best estimate of 
future revenue, earnings and cash flows as well as our discount rate adjusted for risk. 

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.  

In reviewing goodwill for impairment, we have the option to first assess qualitative factors to determine whether the existence 
of events or circumstances leads to a determination that it is more likely than not that the estimated fair value of a reporting unit 
is less than its carrying amount.  If we elect to perform a qualitative assessment and determine that an impairment is more likely 
than not, the entity is then required to perform the existing two-step quantitative impairment test (described below), otherwise no 
further analysis is required.  We also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-
step quantitative impairment test.   

The goodwill impairment test is a two-step process performed at the reporting unit level.  The first step of the goodwill 
impairment test compares the fair value of a reporting unit with its carrying value (including goodwill).  If the reporting unit's fair 
value exceeds its carrying value, no further procedures are required.  However, if the reporting unit's fair value is less than its 
carrying value, an impairment of goodwill may exist, requiring a second step to be performed.  Step two of this test measures the 
amount of the impairment loss, if any.  Step two of this test requires the allocation of the reporting unit's fair value to its assets 
and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of 
goodwill as if the reporting unit were being acquired in a business combination.  If the implied fair value of goodwill is less than 
the carrying value, the difference is recorded as a goodwill impairment charge in operations.  

The fair values of the reporting units are determined based on a weighting of the income approach, market approach and 
market transaction approach.  The income approach is a valuation technique in which fair value is based from forecasted future 
cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and 
debt capital as of the valuation date.  The forecast used in our estimation of fair value was developed by management based on a 
contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty 
in government spending, pricing pressure and opportunities).  The discount rate utilizes a risk adjusted weighted average cost of 
capital.  The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an 
actual arm's length transaction.  The technique consists of undertaking a detailed market analysis of publicly traded companies 
that provides a reasonable basis for comparison to us.  Valuation ratios, which relate market prices to selected financial statistics 
derived from comparable companies, are selected and applied to us 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 provides a reasonable basis for comparison to us.  Valuation ratios, which relate market 
prices to selected financial statistics derived from comparable companies, are selected and applied to us 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 our market capitalization (per share stock price 
times the number of shares outstanding) and calculate an implied control premium (the excess of the sum of the reporting units' 
fair values over the market capitalization), and then assess the reasonableness of our implied control premium.

We have elected to perform our annual review as of October 31st of each calendar year.  The results of our annual goodwill 
impairment test as of October 31, 2019 indicated that the estimated fair value of each reporting unit substantially exceeded its 
respective carrying value.  In addition, management monitors events and circumstances that could result in an impairment.  A 
significant amount of judgment is involved in determining if an indicator of impairment has occurred between annual testing dates.  
Events that could cause the fair value of our long-lived assets to decrease include: changes in our business environment or market 
conditions; a material change in our financial outlook, including declines in expected revenue growth rates and operating margins; 
or a material decline in the market price for our stock.  If any impairment were indicated as a result of a review, we would recognize 
a loss based on the amount by which the carrying amount exceeds the estimated fair value.

Due to the many variables inherent in the estimation of a reporting unit's fair value and the relative size of our recorded 

goodwill, differences in assumptions may have a material effect on the results of our goodwill impairment analysis.

23

 
Accounting for 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% likelihood of being realized upon ultimate settlement 
with the relevant tax authority.  The determination that a tax position meets the "more likely than not" criteria requires a significant 
amount of judgment, which may differ significantly from what is ultimately accepted by the relevant taxing authority.

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, 2019, we had $36.5 million outstanding 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 a $0.2 million effect on our interest 
expense for the year ended December 31, 2019.

We do not use derivative financial instruments for speculative or trading purposes.  When we have excess cash, we invest in 
short-term, investment grade, interest-bearing securities.  Our investments are made in accordance with an investment policy.  
Under this policy, no investment security can have a maturity exceeding six months and the weighted average maturity of the 
portfolio cannot exceed 60 days.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of ManTech International Corporation

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  ManTech  International  Corporation  and  subsidiaries  (the 
"Company") as of December 31, 2019 and 2018, 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, 2019, and the related notes 
and the schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial 
statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and 
the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity 
with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2019, based on criteria established in 
Internal  Control  -  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission and our report dated February 21, 2020, expressed an unqualified opinion on the Company's internal control over 
financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on 
the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error 
or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether 
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting 
principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial 
statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that 
were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are 
material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective,  or  complex  judgments.  The 
communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and 
we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the 
accounts or disclosures to which they relate.

Income Taxes - Unrecognized Tax Benefits - Refer to Notes 2 and 13 to the financial statements

Critical Audit Matter Description

The Company’s other long-term liabilities includes unrecognized tax benefits related to research and development tax credits. 
During the year ended December 31, 2019, the Company recognized an increase in unrecognized tax benefits of approximately 
$7.7 million related to an increase in research and development tax credits available for tax years 2016-2018 and $1.8 million for 
the 2019 tax year. The Company is subject to examination by the Internal Revenue Service (“IRS”) for years subsequent to 2014.   

The Company’s measurement of unrecognized tax benefits involves significant estimates and management judgment and includes 
complex considerations of the Internal Revenue Code, related regulations, case law, and prior-year audit settlements. Given the 
complexity and the subjective nature of the research and development tax credits that remain open for examination by the IRS, 
evaluating management’s estimates relating to their determination of unrecognized tax benefits required extensive audit effort and 
a high degree of auditor judgment, including involvement of our income tax specialists.

26

How the Critical Audit Matter Was Addressed in the Audit

Our principal audit procedures to evaluate management’s estimates of unrecognized tax benefits related to research and development 
tax credits included the following, among others:

•  We evaluated the appropriateness and consistency of management’s methods and assumptions used in the identification, 
recognition, measurement, and disclosure of unrecognized tax benefits, which included testing the effectiveness of the related 
internal controls.

•  With the assistance of our income tax specialists:

  We read and evaluated management’s documentation, including relevant accounting policies and information obtained 
by management from outside tax specialists, that detailed the computational basis of the unrecognized tax benefits.
  We evaluated the reasonableness of management’s judgments regarding the future resolution of the unrecognized tax 

benefits, including an evaluation of the technical merits of the unrecognized tax benefits.

  We evaluated whether management had appropriately considered new information that could significantly change the 

recognition, measurement or disclosure of the unrecognized tax benefits.

  We evaluated the reasonableness of management’s estimates by considering how tax law, including statutes, regulations 

and case law, impacted management’s judgments.

•  We tested the mathematical accuracy of management’s calculations. 

Revenue Recognition - Refer to Notes 2 and 3 to the financial statements

Critical Audit Matter Description 

The Company recognizes revenue on contracts over time when there is a continuous transfer of control to the customer over the 
duration of the contract as the services are rendered. The accounting conclusions for contracts involves judgment, particularly as 
it relates to determining the amount, timing and presentation of revenue that will be recognized for each performance obligation 
within the contract, and the distinct number of performance obligations represented by the contract. 

On certain contracts, revenue is recognized over time using a cost-based input method that measures the extent of progress towards 
completion  of  a  performance  obligation.  Contract  costs  include  labor,  material  and  allocable  indirect  expenses.  Revenue  is 
recognized proportionally as contract costs are incurred plus estimated fees. Management must make assumptions and estimates 
regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length 
of time to complete the performance obligation, execution by subcontractors, the availability and timing of funding from our 
customer and overhead cost rates, among other variables. A significant change in one or more of these estimates could affect the 
profitability of the Company’s contracts. 

Given the judgments necessary to determine the amount, timing and presentation of revenue and to estimate total costs and fees 
for the performance obligations that recognize revenue using a cost-based input method, auditing such estimates required extensive 
audit effort due to the volume and complexity of these contracts and a high degree of auditor judgment when performing audit 
procedures  and  evaluating  the  results  of  those  procedures.  For  all  contracts,  understanding  and  differentiating  the  number  of 
performance obligations contained in the contract represented a high degree of auditor judgment because of the variety of contracts 
and services promised and the interrelationship among those elements. 

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s conclusion on amount, timing and presentation of revenue recognition, as well as 
the estimates of total costs and fees for the performance obligations that recognize revenue using a cost-based input method 
included the following, among others: 

•  We tested the effectiveness of controls over contract revenue, including management’s controls over the initial setup of new 

contract arrangements and the estimates of total costs and fees for performance obligations.

•  We developed an expectation of revenue and compared it to the recorded balance.
• 

For a selection of contracts we performed elements of the following for each contract:
  Evaluated the terms and conditions of each contract and the appropriateness of the accounting treatment in accordance 

with generally accepted accounting principles by: 

Inspecting the executed contract to test that the facts on which management’s conclusions were reached were 
consistent with the actual terms and conditions of the contract.

  Evaluating the contract within the context of the five-step model prescribed by ASC 606, Revenue from Contracts 
with Customers, and evaluating whether management’s conclusions were appropriate by evaluating the nature 
of the promises within the contract, the interrelationship of the promised services provided, the pattern by which 
obligations are fulfilled, the number of performance obligations identified, and which party is responsible for 

27

 
fulfillment.
Involving industry experts in evaluating the appropriateness of management’s conclusions.

  Compared the transaction price to the consideration expected to be received based on current rights and obligations under 

the contracts and any modifications that were agreed upon with the customers.

  Tested the accuracy and completeness of the costs incurred to date for the performance obligation.
  Evaluated the estimates of total cost and fees for the performance obligation by: 

  Comparing costs incurred to date to the costs management estimated to be incurred by that date.
  Evaluating management’s ability to achieve the estimates of total cost and fees by performing corroborating 
inquiries with the Company’s project managers, and comparing the estimates to management’s work plans.
  Comparing  management’s  estimates  for  the  selected  contracts  to  costs  and  fees  of  similar  performance 

obligations, when applicable.

  Tested the mathematical accuracy of management’s calculation of revenue for the performance obligation. 

•  We analyzed adjustments in contract estimates recorded during the year to assess whether such adjustments were the result 

of changes in facts and circumstances and not estimates that were previously inaccurate.

Valuation of Acquired Intangible Assets - Refer to Notes 2 and 5 to the financial statements

Critical Audit Matter Description 

During 2019 the Company completed the acquisitions of Kforce Government Solutions, Inc. and H2M for approximately $114.6 
million  and  $38.5  million,  respectively  (collectively  referred  to  as  “the  acquired  entities”). The  Company  accounted  for  the 
acquisitions under the acquisition method of accounting for business combinations. Accordingly, the purchase price was allocated 
to the assets acquired and liabilities assumed based on their respective fair values, including customer relationship and backlog 
intangible assets with an aggregate fair value of $46.6 million. The Company estimated the fair value of the customer relationship 
and backlog intangible assets using the excess earnings method (income approach), which is a specific discounted cash flow 
method. The fair value determination of the customer relationship and backlog intangible assets required management to make 
significant estimates and assumptions related to future revenue, earnings and cash flows, as well as discount rates adjusted for 
risk. 

We identified the customer relationship and backlog intangible assets for the acquired entities as a critical audit matter because 
of the significant estimates and assumptions management made to determine the fair value these assets. This required a high degree 
of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists, when performing 
audit procedures to evaluate the reasonableness of management’s forecast of future revenue, earnings and cash flows, and the 
selection of discount rates adjusted for risk. 

How the Critical Audit Matter Was Addressed in the Audit 

Our audit procedures related to the forecast of future cash flows and the selection of customer attrition rates and discount rates 
for the customers relationships and backlog intangible assets for the acquired entities included the following, among others:

•  We tested the effectiveness of controls over the valuation of the customer relationship and backlog intangible assets, including 

management’s controls over forecasts of future cash flows and the selection of discount rates.

•  We assessed the reasonableness of management’s forecast of future cash flows by comparing the projections to historical 

results. 

•  With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) valuation methodologies and (2) 
discount rates, which included testing the source information underlying the determination of the discount rates, testing the 
mathematical accuracy of the calculations, and developing a range of independent estimates and comparing those to the 
discount rates selected by management.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Years Ended December 31, 2019, 2018 and 2017 

1.  Description of the Business 

ManTech International Corporation (depending on the circumstances, “ManTech” “Company” “we” “our” “ours” or “us”) 
provides mission-focused technology solutions and services for U.S. defense, intelligence community and federal civilian agencies.  
We  excel  in  full-spectrum  cyber,  data  collection  &  analytics,  enterprise  IT,  systems  engineering  and  software  application 
development solutions that support national and homeland security. 

2.  Summary of Significant Accounting Policies 

Principles  of  Consolidation  -  Our  consolidated  financial  statements  include  the  accounts  of  ManTech  International 
Corporation, subsidiaries we control and variable interest entities that are required to be consolidated.  All intercompany accounts 
and transactions have been eliminated. 

Use of Accounting Estimates - We prepare our consolidated financial statements in conformity with U.S. GAAP, which 
requires 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 us.  Therefore, actual amounts could differ from these estimates. 

Business Combinations - The accounting for our business combinations consists of allocating the purchase price to tangible 
and intangible assets acquired and liabilities assumed based on their estimated fair values, with the excess recorded as goodwill. 
We have up to one year from the acquisition date to use information as of each acquisition date to adjust the fair value of the 
acquired assets and liabilities, which may result in material changes to their recorded values with an offsetting adjustment to 
goodwill.  Determining the fair value of assets acquired and liabilities assumed requires significant judgment, which includes, 
among other factors, analysis of historical performance and estimates of future performance.  In some cases, we have used discounted 
cash flow analyses, which were based on our best estimate of future revenue, earnings and cash flows as well as our discount rate, 
adjusted for risk, and estimated attrition rates.   

Fair Value of Financial Instruments - The carrying value of our cash and cash equivalents, accounts receivable, accounts 

payable and accrued expenses approximate their fair value because of the short-term nature of these amounts. 

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. 

Contract Assets  - Amounts  are  invoiced  as  work  progresses  in  accordance  with  agreed-upon  contractual  terms,  either  at 
periodic intervals or upon achievement of contractual milestones.  Generally, revenue recognition occurs before billing, resulting 
in contract assets.  These contract assets are referred to as unbilled receivables and are reported within receivables, net on our 
consolidated balance sheet.

Billed Receivables - Amounts billed and due from our customers are classified as billed receivables and are reported within 
receivables, net on the consolidated balance sheet.  The portion of the payments retained by the customer until final contract 
settlement is not considered a significant financing component because the intent is to protect the customer.

Goodwill - The purchase price of an acquired business is allocated to the tangible assets, financial assets and separately 
recognized intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as 
goodwill.  We review goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying 
value of long-lived assets may not be fully recoverable.  We have elected to perform this annual review as of October 31st of each 
calendar year.

In reviewing goodwill for impairment, we have the option to first assess qualitative factors to determine whether the existence 
of events or circumstances leads to a determination that it is more likely than not that the estimated fair value of a reporting unit 
is less than its carrying amount.  If we elect to perform a qualitative assessment and determine that an impairment is more likely 
than not, the entity is then required to perform the existing two-step quantitative impairment test (described below), otherwise no 
further analysis is required.  We also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-
step quantitative impairment test. 

35

The goodwill impairment test is a two-step process performed at the reporting unit level.  The first step of the goodwill 
impairment test compares the fair value of a reporting unit with its carrying amount (including goodwill).  If the reporting unit's 
fair value exceeds its carrying value, no further procedures are required.  However, if the reporting unit's fair value is less than its 
carrying value, an impairment of goodwill may exist, requiring a second step to be performed.  Step two of this test measures the 
amount of the impairment loss, if any.  Step two of this test requires the allocation of the reporting unit's fair value to its assets 
and liabilities, including any unrecognized intangible assets in a hypothetical analysis that calculates the implied fair value of 
goodwill as if the reporting unit were being acquired in a business combination.  If the implied fair value of goodwill is less than 
the carrying value, the difference is recorded as a goodwill impairment charge in operations.  

The fair values of the reporting units are determined based on a weighting of the income approach, market approach and 
market transaction approach.  The income approach is a valuation technique in which fair value is based from forecasted future 
cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and 
debt capital as of the valuation date.  The forecast used in our estimation of fair value was developed by management based on a 
contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty 
in government spending, pricing pressure and opportunities).  The discount rate utilizes a risk adjusted weighted average cost of 
capital.  The market approach is a valuation technique in which the fair value is calculated based on market prices realized in an 
actual arm's length transaction.  The technique consists of undertaking a detailed market analysis of publicly traded companies 
that provides a reasonable basis for comparison to us.  Valuation ratios, which relate market prices to selected financial statistics 
derived from comparable companies, are selected and  applied to us 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 provides a reasonable basis for comparison to us.  Valuation ratios, which 
relate  market  prices  to  selected  financial  statistics  derived  from  comparable  companies,  are  selected  and  applied  to  us  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 our market capitalization (per 
share stock price times the number of shares outstanding) and calculate an implied control premium (the excess of the sum of the 
reporting units' fair values over the market capitalization) and then assess the reasonableness of our implied control premium.   

Other Intangible Assets - Contract rights and other intangible assets are amortized primarily using the pattern of benefits 

method over periods ranging from one year to twenty-five years.  

We  account  for  the  cost  of  computer  software  developed  or  obtained  for  internal  use  in  accordance  with ASC  350-985, 

Intangibles - Goodwill and Other - Software.  These capitalized software costs are included in other intangible assets, net. 

We account for software development costs related to software products for sale, lease or otherwise marketed in accordance 
with Accounting Standards Codification (ASC)  985-20, Software - 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 period of five years or other such shorter period as may 
be required.  

Leases - We adopted ASC 842, Leases, on January 1, 2019. We elected to apply the provisions of the standard as of the date 
of adoption, and, therefore, have not restated prior comparative periods. Upon adoption, we recorded operating lease obligations 
of $129.6 million and operating lease right of use (ROU) assets of $118.7 million.  We elected the practical expedient to recognize 
the lease payments related to short-term leases as profit or loss on a straight-line basis over the lease term and variable lease 
payments in the period in which the obligation for those payments are incurred. We also elected the following transition related 
practical expedients: not to reassess whether expired or existing contracts are or contain leases, not to reassess lease classification 
as determined under ASC 840 and not to reassess initial direct costs from any existing lease.  We elected the practical expedient 
as an accounting election not to separate nonlease components from lease components on all classes of underlying assets.  Our 
leases  include  nonlease  components  such  as  common  area  maintenance,  utilities  and  operating  expenses. Additionally,  we 
implemented internal controls and key system functionality to enable the preparation of financial information upon adoption.  ASC 
842 had a material impact on our consolidated balance sheet, but did not have an impact on our consolidated income statement. 
The most significant impact was the recognition of ROU assets and lease obligations for operating leases, while our accounting 
for finance leases remained substantially unchanged.

We determine if a contract is or contains a lease at inception. A contract is or contains a lease if the contract conveys the right 
to control the use of identified property or equipment (an identified asset) for a period of time in exchange for consideration.  We 
have the right to control the use of the identified asset when we have both of the following: the right to obtain substantially all of 
36

the  economic  benefits  from  use  of  the  identified  asset  and  the  right  to  direct  the  use  of  the  identified  asset.    In  making  this 
determination, we consider all relevant facts and circumstances.  We reassess whether a contract is or contains a lease only if the 
terms and conditions of the contract are changed.  We account for lease components and nonlease components associated with a 
lease as a single lease component. Operating leases are included in Operating lease right of use assets, Operating lease obligations
—current and Operating lease obligations—long term on our consolidated balance sheets. Finance leases are included in Property 
and equipment—net, Accounts payable and other accrued expenses and Other long-term liabilities on our consolidated balance 
sheets.

Our ROU asset is recognized as the lease obligation, any initial indirect costs and any prepaid lease payments, less any lease 
incentives. Our lease obligations are recognized based on the present value of the future minimum lease payments over the lease 
term at commencement date.  Our lease payments consist of amounts relating to the use of the underlying asset during the lease 
term, specifically fixed payments, payments to be made in optional periods when we are reasonably certain to exercise an option 
to extend the lease or not to exercise an option to terminate the lease and the amounts probable of being owed by us under residual 
guarantees.  Our variable lease payments are excluded in measuring ROU assets and lease obligations because they do not depend 
on an index or a rate or are not in substance fixed payments.  We exclude lease incentives and initial direct costs incurred from 
our lease payments.  Our leases typically do not provide an implicit rate, we use our incremental borrowing rate based on the 
information available at the commencement date in determining the present value of future payments.

For operating leases, after lease commencement, we measure our lease obligation for each period at the present value of any 
remaining lease payments, discounted by using the rate determined at lease commencement.  In our consolidated statement of 
income, we recognize a single operating lease expense calculated on a straight-line basis over the remaining lease term.  The 
depreciation of the ROU asset increases each year as a result of the declining lease obligation balance.  Variable lease payments 
are not recognized in the measurement of the lease obligation; they are recognized in the period in which the related obligation 
has been incurred.

For finance leases, after lease commencement, we measure our lease obligation by using the effective interest rate method.  
In each period, the lease obligation will be increased to reflect the interest that is accrued on the related lease obligation by using 
the appropriate discount rate, offset by a decrease in the lease obligation resulting from the periodic lease payments.  We recognize 
the ROU asset at cost, reduced by any accumulated depreciation.  The ROU asset is depreciated on a straight-line basis.  Together, 
the  interest  expense  and  depreciation  expense  result  in  a  front-loaded  expense  profile.   We  will  present  interest  expense  and 
depreciation expense separately on our consolidated statement of income.

In our consolidated statement of income, we recognize lease expense within general and administrative expense or cost of 
goods sold depending on the use of the underlying lease. For leases classified as financing, the interest on lease obligations is 
classified within interest expense.

Property and Equipment - Property and equipment are recorded at original cost to us.  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. 

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, Compensation - General - 
Deferred Compensation - Rabbi Trust, 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 us.  The assets held by the rabbi 
trusts are recorded at cash surrender value in our consolidated financial statements as Employee supplemental savings plan assets 
with a related liability to employees recorded as a deferred compensation liability in accrued retirement. 

Investments - Investments where we have the ability to exercise significant influence, but we do not control, are accounted 
for under the equity method of accounting and are included in Other assets on our consolidated balance sheets.  Significant influence 
typically exists if we have a 20% to 50% ownership interest in the investee.  Under this method of accounting, our share of the 
net earnings (losses) of the investee is included in Equity in earnings (losses) of unconsolidated subsidiaries on our consolidated 
statement of income.

Investments where we have less than 20% ownership interest in the investee and lack the ability to exercise significant influence 
are accounted for under the cost method.  Under the cost method, we recognize our investment in the stock of an investee as an 
asset.  The investment is measured initially at cost.  We recognize as income dividends received that are distributed from net 
accumulated earnings.  Dividends received in excess of earnings are considered a return of investment and are recorded as reductions 
of costs of the investment.  Impairment is assessed at the individual investment level.  An investment is impaired if the fair value 
37

of the investment is less than its costs.  If it is determined that the impairment is other than temporary, then an impairment loss is 
recognized in earnings.  The fair value of the investment would become the new cost basis of the investment and will not be 
adjusted for subsequent recoveries in fair value.

Deferred Contract Costs - Costs of obtaining or fulfilling a contract that meet the criteria in ASC 340, Other Assets and 
Deferred Costs, are capitalized and amortized on a systematic basis that is consistent with the transfer of goods or services to the 
customer.  Deferred contracts costs are reported on our consolidated balance sheet within current or non-current other assets based 
on the expected life of the related contract.  At December 31, 2019, we had $9.4 million of deferred contract costs related to the 
fulfillment of future contract obligations.  For the year ended December 31, 2019 we recorded amortization expense of $2.5 million. 

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 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. 

Contract Liabilities - We receive advances and milestone payments from our customers on selected contracts that exceed 
revenue earned to date, resulting in contract liabilities.  Contract liabilities typically are not considered a significant financing 
component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect 
us from the customer failing to adequately complete some or all of its obligations under the contract.  Contract liabilities are 
reported on our consolidated balance sheet on a net contract basis at the end of each reporting period.

Revenue Recognition - On January 1, 2018, we adopted ASC  606, Revenue from Contracts with Customers, using the modified 
retrospective method applied to those contracts that were not substantially complete as of January 1, 2018.  ASC 606 outlines a 
five-step model whereby revenue is recognized as performance obligations within the contract are satisfied. ASC 606 also requires 
new, expanded disclosures regarding revenue recognition.  We recognized the cumulative effect of adopting ASC 606 as an increase 
to the 2018 opening balance of retained earnings in the pretax amount of $0.8 million, with the impact primarily related to fixed-
price contracts.  Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period 
amounts were not adjusted and continue to be reported in accordance with ASC 605, Revenue Recognition.  Revenue for the year 
ended December 31, 2018 increased $2.4 million as a result of applying ASC 606.

We account for a contract when: both we and the customer approve and commit; our rights and those of the customer are 
identified, payment terms are identified; the contract has commercial substance; and collectability of consideration is probable.  
At contract inception, we identify the distinct goods or services promised in the contract, referred to as performance obligations. 
Then we determine the transaction price for the contract; the consideration to which we can expect in exchange for the promised 
goods or services in the contract.  The transaction price can be a fixed or variable amount.  It is common for our contracts to contain 
award fees, incentive fees or other provisions that can either increase or decrease the transaction price.  These variable amounts 
generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based 
upon customer discretion.  We estimate variable consideration at the most likely amount to which we expect to be entitled.  We 
include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue 
recognized will not occur when the uncertainty associated with the variable consideration is resolved.  Our estimates of variable 
consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment 
of our anticipated performance and historical, current and forecasted information that is reasonably available to us.  The transaction 
price is allocated to each distinct performance obligation using our best estimate of the standalone selling price for each distinct 
good or service promised in the contract.  The primary method used to estimate standalone selling price is the expected cost plus 
a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate 
margin for that distinct good or service promised.  Revenue is recognized when, or as, the performance obligation is satisfied.

We recognize revenue over time when there is a continuous transfer of control to our customer.  For our U.S. government 
contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the U.S. government 
to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any 
work in process.  When control is transferred over time, revenue is recognized based on the extent of progress towards completion 
of the performance obligation.  Based on the nature of the products and services provided in the contract, we use our judgment to 
determine if an input measure or output measure best depicts the transfer of control over time.  For services contracts, we typically 
satisfy our performance obligations as services are rendered.  We typically use a cost-based input method to measure progress.  
Contract costs include labor, material and allocable indirect expenses.  Revenue is recognized proportionally as contract costs are 
incurred plus estimated fees.  For time-and-material contracts, we bill the customer per labor hour and per material, and revenue 
is recognized in the amount invoiced since the amount corresponds directly to the value of our performance to date.  For stand-
ready service contracts, a time-elapsed output method is used to measure progress, and revenue is recognized straight-line over 
the term of the contract.  If a contract does not meet the criteria for recognizing revenue over time, we recognize revenue at a point 
38

in time.  Revenue is recognized at the point in time when control of the good or service is transferred to our customer.  We consider 
control to transfer when we have a present right to payment and our customer has legal title.  Determining a measure of progress 
and when control transfers requires us to make judgments that affect the timing of when revenue is recognized.  Essentially all of 
our contracts satisfy their performance obligations over time.

Contracts are often modified to account for changes in contract specifications and requirements.  Contract modifications 
impact the contract when the modification either creates a new performance obligation or changes the existing enforceable rights 
and obligations. The effect of a contract modification on the transaction price and our measure of progress for the performance 
obligation to which it relates is recognized as a cumulative adjustment to revenue and profit.  Furthermore, a significant change 
in one or more estimates could affect the profitability of our contracts.  We recognize adjustments in estimated profit on contracts 
in the period identified.  The impact of adjustments in contract estimates can be reflected in either revenue or operating expenses 
on our consolidated statement of income. 

We have an Estimate at Completion process in which management reviews the progress and execution of our performance 
obligations.  As part of this process, management reviews information including, but not limited to, any outstanding key contract 
matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes 
in estimates of revenue and costs.  The risks and opportunities include management’s judgment about the ability and cost to achieve 
the contract milestones and other technical contract requirements.  Management must make assumptions and estimates regarding 
labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to 
complete the performance obligation, execution by our subcontractors, the availability and timing of funding from our customer 
and overhead cost rates, among other variables.  A significant change in one or more of these estimates could affect the profitability 
of our contracts.  For the year ended December 31, 2019, the aggregate impact of adjustments in contract estimates increased our 
revenue by $11.3 million.  No adjustment on any one contract was material to our consolidated financial statements for the year 
ended December 31, 2019.

Results for 2017 were reported in accordance with ASC 605.  Revenue for cost-reimbursable contracts were recorded as 
reimbursable costs were incurred, including an estimated share of the applicable contractual fees earned.  For performance-based 
fees under cost-reimbursable contracts, we recognized the relevant portion of the expected fee to be awarded by the customer at 
the time such fee can be reasonably estimated, based on factors such as our prior award experience and communications with the 
customer regarding performance, or upon approval by the customer.  For time-and-materials contracts, revenue was recognized 
to the extent of billable rates times hours delivered plus materials and other reimbursable costs incurred.  For long-term fixed-
price contracts, revenue was recognized at a rate per unit as the units were delivered or by other methods to measure services 
provided.    Revenue  from  other  long-term  fixed-price  contracts  were  recognized  ratably  over  the  contract  period  or  by  other 
appropriate methods to measure services provided.  Contract costs were 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, Revenue Recognition 
- Construction-Type and Production-Type Contracts, we applied the percentage of completion method.  Under the percentage of 
completion method, income was 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 required estimating the total revenue and total contract cost at 
completion of the contract.  These estimates were periodically reviewed and revisions were made as required using the cumulative 
catch-up method.  The impact on revenue and contract profit as a result of these revisions were included in the periods in which 
the revisions were made.  Estimated losses on contracts at completion were recognized when identified. In certain circumstances, 
revenue was recognized when contract amendments were not finalized. 

Contract Costs - Contract costs include direct labor, direct materials, overhead and, when applicable, general and administrative 
expenses.  Incremental costs of obtaining a contract that we expect to recover are recognized as deferred contract costs and are 
amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services.  Other incremental 
costs are expensed when incurred.  Costs of fulfilling a contract that relate directly to a contract or to an anticipated contract that 
can be specifically identified, generate or enhance resources that will be used in satisfying future performance obligations and are 
expected to be recovered are recognized as deferred contract costs and amortized on a systematic basis that is consistent with the 
transfer of the goods or services to the customer.  Other costs of fulfilling a contract (costs of wasted materials, labor or other 
resources to fulfill the contracts that were not reflected in the price of the contract and costs that relate to satisfied performance 
obligations in the contract) are expensed when incurred. 

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 include stock-based compensation, as well as 
depreciation  and  amortization  expenses  related  to  the  general  and  administrative  function.    We  recognize  interest  related  to 
unrecognized tax benefits within interest expense and penalties related to unrecognized tax benefits in general and administrative 
39

 
expenses.   

We classify indirect costs incurred as cost of services and general and administrative expenses in the same manner as such 

costs are defined in our disclosure statements under U.S. Government Cost Accounting Standards.

Depreciation and Amortization Method - Furniture and office equipment are depreciated using the straight-line method with 
estimated useful lives ranging from one year to seven years.  Leasehold improvements are amortized using the straight-line method 
over the shorter of the asset's useful life or the term of the lease. 

Stock-based Compensation - We account for stock-based compensation in accordance with ASC 718, Compensation - Stock 
Compensation, which 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 of stock options on the dates of grant for our stock options.  
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.  The grant date fair value of the restricted stock is equal to the closing market price of our 
common stock on the date of grant.  The compensation expense for restricted stock is recognized over the service period and is 
based on the grant date fair value of the shares.  The grant date fair value of the restricted stock unit (RSU) is equal to the closing 
market price of our common stock on the grant date less the present value of dividends expected to be awarded during the service 
period.  We recognize the grant date fair value of RSUs of shares we expect to issue as compensation expense ratably over the 
requisite service period.  We account for forfeitures as they occur.   

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% likelihood of being realized upon ultimate settlement 
with the relevant tax authority.  

Foreign-Currency Translation - All assets and liabilities of foreign subsidiaries are translated into U.S. dollars at fiscal year-
end exchange rates.  Income and expense items are translated at average monthly exchange rates prevailing during the fiscal year.  
The resulting translation adjustments are recorded as a component of accumulated other comprehensive income (loss). 

Comprehensive Income (Loss) - Comprehensive income (loss) consists of net income; translation adjustments, net of tax; 

and actuarial gain (loss) on defined benefit pension plan, net of tax.

Recently Adopted ASUs

ASU 2016-02, Leases (ASC 842) supersedes the leases requirements in ASC 840, Leases.  The objective of ASC 842 is to 
establish the principles that lessees and lessors should apply to report useful information to users of financial statements about the 
amount, timing and uncertainty of cash flows arising from a lease.  We elected to adopt using the modified retrospective method 
at the beginning of the period of adoption, January 1, 2019, through the recognition of a lease obligation and corresponding right 
of use asset.  We elected the following transition related practical expedients; not to reassess whether any expired or existing 
contracts are or contain leases, not to reassess lease classification as determined under ASC 840 and, not to reassess initial direct 
costs for any existing lease.  We have also elected not to apply the recognition and measurement requirements to short-term leases 
(less than 1 year).  Additional details are included in Note 4 below.  

Other ASUs adopted during the year ended December 31, 2019 did not have a material impact on our consolidated financial 

statements.

ASUs effective after December 31, 2019 are not expected to have a material effect on our consolidated financial statements.

3.  Revenue from Contracts with Customers

40

We derive revenue from contracts with customers primarily from contracts with the U.S. government in the areas of defense, 
intelligence, homeland security and other federal civilian agencies.  Substantially all of our revenue is derived from services and 
solutions provided to the U.S. government or to prime contractors supporting the U.S. government, including services by our 
employees and our subcontractors, and solutions that include third-party hardware and software that we purchase and integrate 
as a part of our overall solutions.  Customer requirements may vary from period-to-period depending on the  contract.  We provide 
our services and solutions under three types of contracts: cost-reimbursable, fixed-price and time-and-materials.  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 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.  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  have  one  reportable  segment.    Our  U.S.  government  customers  typically  exercise  independent  decision-making  and 
contracting authority.  Offices or divisions within an agency or department of the U.S. government may directly, or through a 
prime contractor, use our services as a separate customer as long as the customer has independent decision-making and contracting 
authority within its organization.  We treat sales to U.S. government customers as sales within the U.S. regardless of where the 
services are performed.  We generated 99%, 98% and 98% from revenue generated in the U.S. for the years ended December 31, 
2019, 2018 and 2017, respectively.    

The following tables disclose revenue (in thousands) by contract type, customer and prime or subcontractor for the periods 

presented.  Year ended December 31, 2017 amounts have not been adjusted under the modified retrospective method.

million, of which 100% is related to receivables from sales to the U.S. government or from contracts in which we acted as a 
subcontractor to other contractors selling to the U.S. government. We do not believe that we have significant exposure to credit 
risk as billed receivable and unbilled receivables are primarily due from the U.S. government.  The allowance for doubtful accounts 
represents our estimate for exposure to compliance, contractual issues and bad debts related to prime contractors.

We elected to adopt ASC 842 using the modified retrospective method at the beginning of the period of adoption, January 1, 
2019, through the recognition of a lease obligation and corresponding right of use asset. We elected the following transition related 
practical expedients: not to reassess whether any expired or existing contracts are or contain leases, not to reassess lease classification 
as determined under ASC 840, Leases, and, not to reassess initial direct costs for any existing lease. We have also elected not to 
apply the recognition and measurement requirements to short-term leases (less than 1 year).  Prior to the adoption of ASC 842, 
we accounted for leases under the requirements of ASC 840.  The amounts for years prior to the adoption on January 1, 2019 have 
not been adjusted under the modified retrospective method.

ASC 842 Accounting

Our operating leases are primarily made up of real estate. Our variable lease payments do not depend on an index or a rate 
or are not in substance fixed payments. Our leases have remaining lease terms of 1 month to 11 years, some of which include 
options to extend the leases for up to 14 years, and some of which include options to terminate the leases within 1 year. Our 
transportation vehicles and equipment leases include a residual value guarantee, which is a guarantee made to the lessor that the 
value of the underlying asset returned to the lessor at the end of the lease will be at least a specific amount.  We sublease some of 
our real estate space. Sublease income is immaterial and is presented net with the corresponding lease expense. We do not have 
any leases that have not yet commenced due to construction or design of the underlying asset. We recognize payments related to 
short-term leases (less than one year) as expense on a straight-line basis over the lease term and variable lease payments in the 
period in which the obligation for those payments were incurred.  As such, our short-term lease expense for the year ended December 
31, 2019 was $5.4 million.  For the year ended December 31, 2019, we incurred variable lease costs of $2.4 million.

H2M Group (H2M)—On August 8, 2019, we completed the acquisition of H2M through a membership interest purchase 
agreement by and among H2M Group, HHM Holding LLC, and the Members and ManTech International Corporation.  H2M is 
a provider of intelligence and analysis services and solutions primarily to the National Geospatial-Intelligence Agency (NGA). 
This  acquisition  strengthens  our  ability  to  help  key  government  agencies  implement  new  automation  techniques  that  enable 
intelligence  analysts  to  more  efficiently  navigate  large  amounts  of  data  and  distill  critical  information  to  inform  actionable 
intelligence and make mission-critical decisions.

The acquisition was accounted for as a business combination. The results of H2M's operations have been included in our 
consolidated financial statements since that date.  We funded the acquisition with cash on hand and borrowings on our revolving 
credit facility.  

The purchase price of $38.5 million, which includes the finalized working capital adjustment, was preliminarily allocated to 
the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The excess of the purchase price 
over the fair value of assets acquired and liabilities assumed was recorded as goodwill.  As we are still in the process of reviewing 
the fair value of the assets acquired and liabilities assumed, the purchase price allocation for H2M is not complete as of December 31, 
2019.  In accordance with ASC 805, Business Combinations, we expect to finalize our purchase price allocation within one year 
of the acquisition date.

Determining the fair value of assets acquired and liabilities assumed requires significant judgment, which includes, among 
other factors, analysis of historical performance and estimates of future performance of H2M's contracts.  In some cases, we have 

44

used discounted cash flow analyses, which were based on our best estimate of future revenue, earnings and cash flows as well as 
our discount rate adjusted for risk.  

Recognition of goodwill is largely attributed to the value paid for H2M's capabilities to support government agencies in the 
implementation of high-quality geospatial and professional services. The goodwill recorded for this transaction will be deductible 
for  tax  purposes  over  15  years.    The  components  of  other  intangible  assets  associated  with  the  acquisition  were  customer 
relationships and backlog valued at $9.6 million and $2.3 million, respectively. The fair values of the customer relationships and 
backlog were determined using the excess earnings method (income approach) in which the value is derived from an estimation 
of  the  after-tax  cash  flows  specifically  attributable  to  backlog  and  customer  relationships.   Assumptions  used  in  the  analysis 
included revenue and expense forecasts, contributory asset charges, tax amortization benefit and discount rates. Customer contracts 
and  related  relationships  represent  the  underlying  relationships  and  agreements  with  H2M's  existing  customers.    Customer 
relationships  are  amortized  using  the  pattern  of  benefits  method  over  their  estimated  useful  lives  of  approximately  20  years.  
Backlog  is  amortized  using  the  pattern  of  benefits  method  over  its  estimated  useful  life  of  2  years.    The  weighted-average 
amortization period for other intangible assets is 17 years.

For the year ended December 31, 2019, we incurred approximately $0.3 million of acquisition costs related to the H2M 

transaction, which are included in general and administrative expenses in our consolidated statement of income.

Kforce Government Solutions (KGS)—On April 1, 2019, we completed the acquisition of KGS.  KGS was a wholly owned 
subsidiary of the publicly traded commercial technology and staffing company KForce, Inc.  The acquisition was completed 
through  an  equity  purchase  agreement  dated  February 28,  2019,  by  and  among  Kforce  Government  Solutions,  Inc  and  other 
beneficiaries  and  ManTech  International  Corporation.    KGS  provides  services,  IT  solutions,  transformation  and  management 
consulting and data analytics - most notably in the healthcare IT market.  This acquisition expands our presence with important 
customers such as the Department of Veteran Affairs (VA).

The acquisition was accounted for as a business combination. The results of KGS's operations have been included in our 
consolidated financial statements since that date.  We funded the acquisition with cash on hand and borrowings on our revolving 
credit facility.  

The purchase price of $114.6 million, which includes the finalized working capital adjustment, was allocated to the underlying 
assets and liabilities based on their estimated fair value at the date of acquisition.  The excess of the purchase price over the fair 
value of assets acquired and liabilities assumed was recorded as goodwill.  The purchase price allocation of KGS is complete as 
of December 31, 2019.

Determining the fair value of assets acquired and liabilities assumed requires significant judgment, which includes, among 
other factors, analysis of historical performance and estimates of future performance of KGS’s contracts.  In some cases, we have 
used discounted cash flow analyses, which were based on our best estimate of future revenue, earnings and cash flows as well as 
our discount rate adjusted for risk.  

Recognition of goodwill is largely attributed to the value paid for KGS's capabilities to support customers in IT solutions, 

45

transformation and management consulting and data analytics.  A majority of the goodwill recorded will not be deductible for tax 
purposes.  

The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at 
$33.1 million and $1.6 million, respectively.  The fair values of the customer relationships and backlog were determined using the 
excess earnings method (income approach) in which the value is derived from an estimation of the after-tax cash flows specifically 
attributable to backlog and customer relationships.  Assumptions used in the analysis included revenue and expense forecasts, 
contributory asset charges, tax amortization benefit and discount rates. Customer contracts and related relationships represent the 
underlying relationships and agreements with KGS's existing customers.  Customer relationships are amortized using the pattern 
of benefits method over their estimated useful lives of approximately 20 years.  Backlog is amortized straight-line over its estimated 
useful life of 1 year.  The weighted-average amortization period for other intangible assets is 19 years.

For  the  year  ended  December 31,  2019,  we  incurred  approximately  $0.9  million  of  acquisition  costs  related  to  the  KGS 

transaction, which are included in general and administrative expenses in our consolidated statement of income.

6.  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 our Certificate of Incorporation, the holders of the common stock are entitled 
to participate ratably, on a share-for-share basis as if all shares of common stock were of a single class, in such dividends, as may 
be declared by the Board of Directors.  During the years ended December 31, 2019, 2018 and 2017, we declared and paid quarterly 
dividends, in the amount of $0.27, $0.25 and $0.21 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 have 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. 

46

The net income available to common stockholders and weighted average number of common shares outstanding used to 
compute basic and diluted earnings per share for each class of common stock are as follows (in thousands, except per share 
amounts):

Revolving Credit Facility - We maintain a credit agreement with a syndicate of lenders led by Bank of America, N.A., as sole 
administrative agent.  The credit agreement provides for a $500 million revolving credit facility, with a $75 million letter of credit 
sublimit and a $30 million swing line loan sublimit.  The credit agreement also includes an accordion feature that permits us to 
arrange with the lenders for the provision of additional commitments.  The maturity date is August 17, 2022. 

Borrowings under our credit agreement are collateralized by substantially all of our assets and our Material Subsidiaries (as 
defined in the credit agreement) and bear interest at one of the following variable rates as selected by us at the time of borrowing: 
a LIBOR based rate plus market spreads (1.25% to 2.25% based on our consolidated total leverage ratio) or Bank of America's 
base rate plus market spreads (0.25% to 1.25% based on our consolidated total leverage ratio).  The aggregate annual weighted 
average interest rates were 4.11% and 3.91% for the years ended December 31, 2019 and 2018, respectively.

The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain 

48

conditions.  The credit agreement requires us to comply with specified financial covenants, including the maintenance of certain 
leverage  ratios  and  a  certain  consolidated  coverage  ratio.    The  credit  agreement  also  contains  various  covenants,  including 
affirmative covenants with respect to certain reporting requirements and maintaining certain business activities, and negative 
covenants that, among other things, may limit or impose restrictions on our ability to incur liens, incur additional indebtedness, 
make investments, make acquisitions and undertake certain other actions.  As of, and during the fiscal years ending, December 31, 
2019 and 2018, we were in compliance with our financial covenants under the credit agreement.  

There  was  $36.5  million  and  $7.5  million  outstanding  on  our  revolving  credit  facility  at  December 31,  2019  and  2018, 
respectively.  The weighted average borrowings under the revolving portion of the facility during the years ended December 31, 
2019 and 2018 were $37.0 million and $34.2 million, respectively.  The maximum available borrowing under the revolving credit 
facility  at  December 31,  2019  was  $457.7  million.   At  December 31,  2019  and  2018,  we  had  $5.8  million  and  $9.6  million, 
respectively, outstanding on our letter of credit that reduces our availability to borrow under our revolving credit facility.

10.  Commitments and Contingencies 

Contracts with the U.S. government, including subcontracts, are subject to extensive legal and regulatory requirements and, 
from time-to-time, agencies of the U.S. government, in the ordinary course of business, investigate whether our operations are 
conducted in accordance with these requirements and the terms of the relevant contracts.  U.S. government investigations of us, 
whether related to our U.S. government contracts or conducted for other reasons, could result in administrative, civil, or criminal 
liabilities, including repayments, fines or penalties being imposed upon us, or could lead to suspension or debarment from future 
U.S. government contracting activities.  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 has completed our incurred cost audits through 
2016 with no material adjustments.  The remaining audits for 2017 through 2019 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, except for the matter noted below.

An officer of our Company was party to an arbitration proceeding with a former employer relating to a breach of a contract 
claim.  Pursuant to indemnification arrangements we have with this officer, we were exposed to a loss related to this claim.  During 
2019, we settled the claim.  The settlement amount was not material to our consolidated financial statements.

We have $5.8 million outstanding on our letter of credit, of which $5.7 million is related to an outstanding performance bond 
in connection with a contract between ManTech MENA, LLC and Jadwalean International Operations and Management Company 
to fulfill technical support requirements for the Royal Saudi Air Force.

11.  Stockholders' Equity and Stock-Based Compensation 

Common Stock - We have 150,000,000 shares of authorized Class A common stock, par value $0.01 per share.  We have 
50,000,000 shares of authorized Class B common stock, par value $0.01 per share.  On December 31, 2019, there were 26,991,747
shares of Class A common stock outstanding, 244,113 shares of Class A common stock recorded as treasury stock and 13,187,195
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 Executive Chairman and Chairman of the Board), his affiliates, his direct and indirect permitted 
transferees or a group, generally including Mr. Pedersen, such affiliates and permitted transferees, seek to buy all outstanding 
shares), as to which each share of Class A common stock and Class B common stock are entitled to one vote per share.  The Class A 
common stock and the Class B common stock vote together as a single class on all matters submitted to a vote of stockholders, 
including the election of directors, except as required by law.  Holders of common stock do not have cumulative voting rights in 
the election of directors. 

Stockholders are entitled to receive, when and if declared by the Board of Directors from time-to-time, such dividends and 
other distributions in cash, stock or property from our assets or funds legally and contractually available for such purposes subject 
to any dividend preferences that may be attributable to preferred stock that may be authorized.  Each share of Class A common 
stock and Class B common stock is equal in respect to 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 
49

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 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, 2019 and 2018, 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 2016 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees.  The types of 
awards available under the Plan include stock options, restricted stock and RSUs, among others.  Equity 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, 2020, there were 602,681 additional shares 
made available for issuance under the Plan.  Through December 31, 2019, the Board of Directors has authorized the issuance of 
up to 15,148,321 shares under this Plan.  Through December 31, 2019, the remaining aggregate number of shares of our common 
stock available for future grants under the Plan was 6,416,141.  The Plan expires in March 2026.

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, 2019, 2018 and 2017, we recorded $7.5 million, $5.1 
million and $6.3 million of stock-based compensation expense, respectively.  No compensation expense of employees with stock 
awards was capitalized during the years ended December 31, 2019, 2018 and 2017.  For the year ended December 31, 2019, 2018 
and 2017 we recorded $2.1 million, $3.4 million and $2.7 million, respectively, to income tax benefit related to the exercise of 
stock options, vested cancellations and the vesting of restricted stock and restricted stock units.  

Stock Options - Under the Plan, we have issued stock options.  A stock option granted gives the holder the right, but not the 
obligation to purchase a certain number of shares at a predetermined price for a specific period of time.  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, 2019, 2018 and 2017, 
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 
stock option awards on the 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, 2019, 2018

and 2017:

•  Volatility - The expected volatility of the options granted was estimated based upon historical volatility of our share price 

through weekly observations of our trading history.

•  Expected life of options - The expected life of options granted to employees was determined from historical exercises of 
the grantee population.  The options had graded vesting over three years in equal installments beginning on the first 
anniversary of the date of the grant and a contractual term of five years.

•  Risk-free interest rate - The yield on zero-coupon U.S. Treasury strips was used to extrapolate a forward-yield curve. 
This “term structure” of future interest rates was then input into a numeric model to provide the equivalent risk-free rate 
to be used in the Black-Scholes-Merton model based on the expected term of the underlying grants.  

50

•  Dividend yield - The Black-Scholes-Merton valuation model requires an expected dividend yield as an input.  For the 
years ended December 31, 2019, 2018 and 2017, we have calculated our expected dividend yield based on an expected 
annual cash dividend of $1.08 per share, $1.00 per share and $0.84 per share, respectively.

The following table summarizes weighted-average assumptions used in our calculations of fair value for the years ended

Stock Option Activity - The weighted-average fair value of options granted during the years ended December 31, 2019, 2018
and 2017, as determined under the Black-Scholes-Merton valuation model, was $12.07, $10.42 and $6.75, respectively.  Option 
grants that vested during the years ended December 31, 2019, 2018 and 2017 had a combined fair value of $2.5 million, $1.5 
million and $1.7 million, respectively.

Unrecognized compensation expense related to outstanding stock options was $7.4 million as of December 31, 2019, which 

is expected to be recognized over a weighted-average period of 2 years and will be adjusted for forfeitures as they occur.

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 stock issued to members of 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.  The grant date fair value of the restricted stock is equal to the 
closing market price of our common stock on the date of grant.

RSUs - Under the Plan, we issued performance-based and time-based RSUs.  RSUs are not actual shares, but rather a right 
to receive shares in the future.  The shares are not issued and the employee cannot sell or transfer shares prior to vesting and has 
no voting rights until the RSUs vest.  Employees who are granted RSUs do not receive dividend payments during the vesting 
period.  The employees' performance-based RSUs will result in the delivery of shares if (a) performance criteria is met and (b) 
the employee remains employed, in good standing, through the date of the performance period of two years.  The employees' time-
based RSUs will result in the delivery of shares in one-third increments on the first, second and third anniversaries of the date of 
grant. The grant date fair value of the RSUs is equal to the closing market price of our common stock on the grant date less the 
present value of dividends expected to be awarded during the service period. We recognize the grant date fair value of RSUs of 
shares we expect to issue as compensation expense ratably over the requisite service period.

52

RSU Activity - For performance-based RSUs that vested in 2019 and 2018, each RSU awarded resulted in the issuance of 1.5
shares, which were issued net of applicable payroll tax withholdings. The following table summarizes the RSU activity during 
the years ended December 31, 2019 and 2018:

As of December 31, 2019, 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 we 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 $26.7 million, 
$23.5 million and $20.6 million for the years ended December 31, 2019, 2018 and 2017, respectively. 

As of December 31, 2019, we also maintained an Employee Supplemental Savings Plan (ESSP), which is a nonqualified 
deferred compensation plan for certain key employees.  Under this plan, eligible employees could 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 us for 
benefit of the participating employees.  The trust investments are in the form of variable universal life insurance products, which 
are owned by us.  These investments seek to replicate the return of the participant investment elections.  Employee contributions 
to this plan were approximately $3.4 million, $3.4 million and $3.0 million for the years ended December 31, 2019, 2018 and 
2017, respectively.

We maintained a nonqualified supplemental defined benefit pension plan for certain retired employees of an acquired company 
as of December 31, 2019.  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, 2019 and 2018, 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 was $0.7 million and $0.8 million at December 31, 2019 and 2018, respectively.

At  December 31,  2019,  we  had  state  and  foreign  net  operating  losses  of  approximately  $12.2  million  and  $7.9  million, 
respectively.  The state net operating losses expire beginning 2027 through 2038.  We recorded a full valuation allowance against 
the foreign net operating losses and a partial valuation allowance against the state net operating losses, as we do not believe those 
losses will be fully utilized in the future. 

A reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits is as follows 

(in thousands):

The total liability for gross unrecognized tax benefits as of December 31, 2019, 2018 and 2017 includes $9.6 million, $0.4 
million and $0.2 million, respectively, of unrecognized net tax benefits which, if ultimately recognized, would reduce our annual 
effective tax rate in a future period.  These liabilities, along with liabilities for interest and penalties, are included in accounts 
payable and accrued expenses and Other long-term liabilities in our consolidated balance sheet.  Interest, which is included in 
Interest expense in our consolidated statement of income, was not material for all years presented.

During the year ended December 31, 2019, we recognized an increase in unrecognized tax benefits of approximately $7.7 
million related to an increase in research and development tax credits available to us for tax years 2016-2018 and $1.8 million for 
the 2019 tax year.

We are 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.  We are no longer subject to U.S. federal or 
non-U.S.  income  tax  examinations  by  tax  authorities  for  the  years  before  2015.   We  are  no  longer  subject  to  U.S.  state  tax 
examinations by tax authorities for the years before 2014.  We believe it is reasonably possible that within the next year our  
unrecognized tax benefits may decrease by $1.9 million due to the acceptance of a portion of our amended research and development 
credits.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

We have had no disagreements with our 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 

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, does 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 us have been detected.  These inherent limitations include the realities that judgments in decision-making can be faulty 
and that breakdowns can occur because of a simple error or mistake.  Additionally, controls can be circumvented by the individual 
acts of some persons, by collusion of two or more people, or by management's override of the control.  The design of any system 
of controls also is based in part upon certain assumptions about the likelihood of future events and there can be no assurance that 
any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate 
because of changes in conditions or the degree of compliance with the policies or procedures may deteriorate.  Because of the 
inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. 

Scope of the Assessments - The assessment by our principal executive officer and our principal financial officer of our disclosure 
controls and procedures and the assessment by our management of our internal control over financial reporting included a review 
of procedures and documents and discussions with other employees in our organization in order to evaluate the adequacy of our 
internal control system design.  In the course of the evaluation, we sought to identify exposure to unprevented or undetected data 
errors, control problems or acts of fraud and to confirm that appropriate corrective action, including process improvements, were 
being undertaken.  The assessment also included testing of properly designed controls to verify their effective performance.  Our 
management used the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission in the Internal 
Control-Integrated Framework (2013) to assess the effectiveness of our internal control over financial reporting. 

We assess our disclosure controls and procedures and our internal control over financial reporting on an ongoing basis so that 
the conclusions concerning controls effectiveness can be reported in our Quarterly Reports on Form 10-Q and Annual Reports on 
Form 10-K.  We consider the results of these assessment activities as we monitor our disclosure controls and procedures and our 
internal control over financial reporting.  Our intent is to ensure that disclosure controls and procedures and internal control over 
financial reporting will be maintained and updated as conditions warrant.  Among other matters, we sought in our assessment to 
determine whether there were any “material weaknesses” in our internal control over financial reporting, or whether we had 
identified any acts of fraud involving senior management, management or other personnel who have a significant role in our 
internal  control  over  financial  reporting.   This  information  was  important  both  for  the  assessment  generally  and  because  the 
57

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, 2019, our disclosure controls and procedures 
were effective at the reasonable assurance level described above. 

Management's  Report  on  Internal  Control  over  Financial  Reporting  -  Management  is  responsible  for  establishing  and 
maintaining adequate control over financial reporting.  Management used the criteria issued by the Committee of Sponsoring 
Organizations of the Treadway Commission in the Internal Control-Integrated Framework (2013) to assess the effectiveness of 
our internal control over financial reporting.  Based upon the assessments, our management has concluded that, as of December 31, 
2019, 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, 2019, 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 shareholders and the Board of Directors of ManTech International Corporation

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of ManTech International Corporation and subsidiaries (the 
“Company”) as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) 
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on 
criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2019, of the Company 
and our report dated February 21, 2020 expressed an unqualified opinion on those financial statements.

Basis for Opinion 

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 are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. 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.

Definition and Limitations of Internal Control over Financial Reporting

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

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

All statements and assumptions contained in this Annual 
Report that do not relate to historical facts constitute “forward-
looking statements.” These statements can be identified by the 
fact that they do not relate strictly to historical or current facts. 
Forward-looking statements often include the use of words 
such as “may,” “will,” “expect,” “intend,” “anticipate,” “believe,” 
“estimate,” “plan,” and words and terms of similar substance 
in connection with discussions of future events, situations 
or financial performance. While these statements represent 
our current expectations, no assurance can be given that the 
results or events described in such statements will be achieved.

These forward-looking statements are inherently subject to 
risks and uncertainties, and 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: failure to maintain our relationship with the U.S. 
government, or the failure to compete effectively for new 
contract awards or to retain existing U.S. government contracts; 
inability to recruit and retain a sufficient number of employees 
with specialized skill sets or necessary security clearances who 
are in great demand and limited supply; adverse changes in 
U.S. government spending for programs we support, whether 
due to changing mission priorities, socio-economic policies 
or federal budget constraints generally; failure to compete 
effectively for awards procured through the competitive 
bidding process, and the adverse impact of delays resulting 
from our competitors’ protests of new contracts that are 
awarded to us; disruptions to our business or damage to our 
reputation resulting from cyber attacks and other security 
threats; failure to obtain option awards, task orders or funding 
under our contracts; the government renegotiating, modifying 
or terminating our contracts; failure to comply with, or adverse 
changes in, complex U.S. government laws and procurement 
regulations; adverse results of U.S. government audits or 
other investigations of our government contracts; failure to 
successfully integrate acquired companies or businesses into 
our operations or to realize any accretive or synergistic effects 
from such acquisitions; failure to mitigate risks associated 
with conducting business internationally; and adverse changes 
in business conditions that may cause our investments in 
recorded goodwill to become impaired. These and other risk 
factors are more fully discussed in the section entitled “Risk 
Factors” in ManTech’s Annual Report on Form 10-K previously 
filed with the Securities and Exchange Commission on Feb. 
21, 2020, 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 
Annual Report. We undertake no obligation to update any 
forward-looking statement made herein following the date of 
this Annual Report, whether as a result of new information, 
subsequent events or circumstances, changes in expectations 
or otherwise.
