We leverage dedicated subject matter experts, a virtual cyber training range, and our longstanding, acclaimed learning center, ManTech University, in developing customized training solutions for our customers. We also provide supply chain management and logistics services involving the use of sophisticated systems that secure the entire supply chain, from supplies to data.
Human Capital Resources
Our talented people have always been and continue to be our greatest asset. Our ability to deliver enduring value to our customers and their critical missions is enabled by the thoughtful innovation, tireless efforts and steadfast dedication of our people. As of December 31, 2021, we employed approximately 9,800 people, 81% of whom hold security clearances and approximately 45% of whom are veterans. The highly-skilled and cleared nature of our talent base enables us to quickly respond to customer needs and provides us with opportunities to understand and help solve our customers’ most challenging national security problems. Security clearance requirements, and the time and processes required to attain and maintain clearances, serve as a significant barrier to entry in our market.
At ManTech, we believe in the abilities and potential of our people. We invest in attracting, developing, and retaining our talented workforce by providing exciting work assignments and opportunities for skill development and career growth, and we recognize and reward our people for their contributions and accomplishments. In turn, our loyal and career-oriented professionals enjoy great trust and success in helping our customers meet the mission-critical needs of our government.
Training and Development
In recognition of our employees’ interest in career mobility and professional development, we have a robust Career Enablement Initiative. ManTech's Career Enablement Initiative is an employee-initiated, leader supported, and enterprise-wide approach to career growth and development. Since inception, we have seen a rapid adoption of the initiative across the enterprise, as management works to incorporate the initiative into our Company’s culture. In addition, we now offer four career path journeys in the areas of Cyber, IT, Program/Project Management, and P&L Leadership, and have seen an increase in mobility of talent across the organization. Our ManTech University training program, established in 2006, serves as a training platform for the entire company, which we augment with our Skillsoft platform that provides a wide variety of training resources for our employees.
Employee Engagement
We continued to focus on the health, safety, and well-being of our employees during the COVID-19 pandemic. We have supported our employees with the accommodations and support that enable them to continue supporting our customers and their missions despite the difficulties of these unprecedented times. We expanded our dedicated team of engagement specialists, both in reach and in scope, to proactively identify areas of vulnerability and connect with potentially affected employees, identify any trends that relate to employee concern, and build engagement strategies to address systemic issues. Always looking to improve, we surveyed our employees to obtain valuable feedback about their experience and our business culture. We formed a COVID-19 task force to monitor and oversee our response to, and management of, challenges related to the pandemic. We developed and issued health and safety protocols and prepared our leaders to support and respond to the needs of our employees. We prioritized the engagement of our employees, providing our employees with timely and transparent communications, demonstrating strong and visible leadership, and reinforcing of our culture of compassion, which we believe helped us maintain business continuity and led to high levels of retention and employee engagement.
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 over half a century. Within the U.S. government, our revenues are well-diversified across a number of intelligence, defense and federal civilian agencies.
Backlog
At December 31, 2021, our backlog was $10.6 billion, of which $1.6 billion was funded backlog. At December 31, 2020, our backlog was $10.2 billion, of which $1.2 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. 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 and days leading up to 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
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.
Our business could be adversely affected by the COVID-19 pandemic or other similar global health pandemics, epidemics and/or other disease outbreaks.
The COVID-19 pandemic (and any future global health pandemics, epidemics and/or other disease outbreaks), and government responses to mitigate the impact of such crises, could adversely impact our ability to operate our business and therefore have a material adverse effect on our business, financial position, results of operations, liquidity and cash flows. Travel restrictions, social distancing guidelines and other preventative measures put in place by health organizations, federal, state, and local governments have altered the manner in which many of our employees work with our customers, and in response, we have modified our operating schedules and staffing and implemented telework or alternate work arrangements where possible. Notwithstanding our implementation of telework and other means of remote work for our employees that support impacted programs and our internal support organizations, some programs we support, by their nature, cannot accommodate remote work. These programs require shiftwork or the implementation of other mitigation strategies that enable us to maintain our workforce in a “mission ready” state, which has resulted in reduced utilization of that portion of the workforce. The COVID-19 pandemic could also affect our contract performance and could also result in increased costs that may not be fully recoverable, adequately covered by insurance, or addressed by the CARES Act or any subsequent legislative or regulatory measures.
Additionally, the COVID-19 pandemic, along with preventative measures put in place by health organizations and federal, state, and local governments, creates ancillary risks to our business, to include the risk of sustained declines in the capital markets, the risk of a sustained economic downturn or recession and other macroeconomic phenomena that could adversely affect customer demand for our services in the future. Furthermore, our business, financial position, results of operations, liquidity and/or cash flows could be adversely and materially affected if the COVID-19 pandemic worsens, lasts significantly longer than anticipated, and/or manifests in additional multiple waves of infection (whether due to new strains of the virus or vaccines providing less protection than expected). Significant and sustained disruptions at our customers could occur, which could in turn have a material adverse effect on our business, financial position, results of operations, liquidity and/or cash flows.
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 hold some of the highest security clearances in the United States. Cleared people 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 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' 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. Like other government contractors, we 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
•inability 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.
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 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.
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.
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 the 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.
Legal and Regulatory Risks
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 may be held 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, 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 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. 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.
Changes in tax laws or unanticipated changes in our tax provision could have a material impact on our profitability and/or operating cash flow.
We are subject to income and other taxes in U.S. and foreign jurisdictions. Changes in applicable U.S. (federal, state and local) or foreign tax laws and regulations, or their interpretation and application have affected and could continue to affect our income tax expense and taxes paid or payable. In addition, we are subject to various audits where depending on the final determination could have a material impact on our tax provision. We are currently under examination by several jurisdictions, including U.S. federal tax years 2016-2018 and amounts submitted for research and development credits for those years.
Beginning in 2022, the Tax Cuts and Jobs Act (TCJA) of 2017 eliminates the option to deduct research and development expenditures currently and requires taxpayers to amortize them over five years pursuant to IRC Section 174. Although Congress is considering legislation that would defer or repeal this provision, we have no assurance this will be enacted. If this provision of the TCJA is not repealed or otherwise modified, it will materially reduce our operating cash flows in 2022.
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. 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 2022. 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 of Directors 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, Chairman Emeritus, effectively controls us, and his interests may not be aligned with those of other stockholders.
As of December 31, 2021, Mr. Pedersen owned approximately 32% 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, 2021, Mr. Pedersen beneficially owned 13,176,695 shares of Class B common stock 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.
Provisions in our charter documents and Delaware law may inhibit potential acquisition bids that our 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 our 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.
General Risk Factors
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, 2021, our goodwill was $1.5 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.

ITEM 3. LEGAL PROCEEDINGS
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.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
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.
The following discussion is intended to provide the readers of our financial statements with a narrative from management’s perspective regarding our financial condition and results of operations, liquidity, and certain other factors that could affect our future results.
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, secure mission & enterprise IT, advanced data analytics, software and systems development, intelligent systems engineering, intelligence mission support and mission operations.
Approximately 99% of our revenues during the year ended December 31, 2021 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) 2021, the U.S. government obligated approximately $387 billion on contracted services. 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.
The President’s GFY 2022 budget proposal included $753 billion for national defense programs. Included in the President’s budget proposal is spending for infrastructure, economic stimulus, and education. In November 2021, the President signed into law the Infrastructure, Investment and Jobs Act (IIJA). To date, the GFY 2022 budget appropriations have not been enacted and continue to be debated by Congress. Since the beginning of GFY 2022, the U.S. government has been, and continues to be, funded through a series of Continuing Resolutions (CR). The current CR is set to expire on March 11, 2022. Absent an approval of GFY 2022 appropriations, or other stop gap spending measures, the U.S. government could experience periodic shutdowns which could materially impact our financial results and liquidity.
In 2021, the U.S. government increased the debt ceiling by nearly $3 trillion. The current debt ceiling is expected to allow the U.S. government to operate into 2023. Exiting 2021, inflation has significantly increased. The Federal Reserve has signaled their intent to increase interest rates over the coming year. Increasing interest rates will increase the amount of the federal budget used to satisfy interest payments on the U.S. debt which could impact the amount of funding allocated to programs that support national defense. While we cannot predict the future of the U.S. government’s spending priorities, we believe the geopolitical aggression of adversarial nations as well as cyber threats from state and non-state actors remain prominent and align well to the services and capabilities we provide to our customers.
COVID-19 Pandemic
In March of 2020, the World Health Organization declared COVID-19 a pandemic. Over the past two years, the pandemic has had a significant impact on the global population and economy. In response to the pandemic, the U.S. government enacted legislation in an attempt to mitigate the economic impacts through stimulus spending. In March 2020, the Coronavirus Aid, Relief and Economic Security (CARES) Act was signed into law. The CARES Act contained a provision (3610) under which government contractors could seek reimbursement for employee's salaries when they are prevented from accessing worksites or are subject to reduced work schedules and cannot telecommute. These provisions were extended through September 30, 2021 when the President signed into law the American Rescue Plan (ARP) Act of 2021. Amounts submitted for reimbursement under the CARES Act diminished significantly in our third quarter of 2021 and costs incurred in our fourth quarter of 2021 were no longer covered.
On September 9, 2021, the President issued an Executive Order requiring all federal employees and contractors supporting
the federal government be vaccinated (or to have an approved accommodation) by December 8, 2021. The vaccination deadline was subsequently extended to January 18, 2022. On December 7, 2021, a federal district judge suspended the enforcement of this order. This suspension is currently under appeal.
We are continuing to monitor impacts of the global outbreak of the COVID-19 pandemic including new variants of the virus, specific impacts and mitigation protocols enacted in regions in which we operate, and the vaccination status of our employees. In preparation of the vaccine mandate and to promote the well-being of our workforce, we have and continue to encourage our employees to get vaccinated (or seek an approved accommodation). We cannot predict the potential impact of the vaccination mandate or the overall evolution of the pandemic and its further impacts on the economy or our business.
Acquisitions
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 2021, we acquired Gryphon Technologies, Inc. (Gryphon) and Technical and Management Assistance Corporation (TMAC). Gryphon provides a broad array of advanced digital and systems engineering capabilities for Department of Defense agencies. TMAC provides advanced data engineering services and solutions that ensure the delivery of vital information to the U.S. Intelligence Community. Since going public in 2002, we have acquired and integrated 34 businesses into our operations.
Pricing
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 expenses either as cost of services or general and administrative in manner consistent with disclosure statements submitted and approved by the Defense Contract Management Agency (DCMA). Effective January 1, 2021, changes in indirect cost allocations reclassified certain expenses from general and administrative to cost of sales (overhead). While this does not impact indirect expenses in total, it does reduce general and administrative as compared to prior periods.
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.
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, which 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 drivers of the increase in our revenues are revenues from new contract awards, growth on existing contracts and the acquisitions we completed in the prior 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 2022 due to our recent acquisitions, growth on existing programs and new contracts.
Cost of services
The increase in cost of services was primarily due to increases in revenues. As a percentage of revenues, direct labor costs were 50% and 49% for the years ended December 31, 2021 and 2020, respectively. As a percentage of revenues, other direct costs, which include subcontractors and third party equipment and materials used in the performance of our contracts, were 36% for both the years ended December 31, 2021 and 2020. With COVID-19 mitigation protocols being reduced or lifted, direct labor has been impacted as employees have begun utilizing paid time off at a normalized level. Profitability has increased due to higher program profits including improved award fees as compared to the prior period.
General and administrative expenses
The decrease in general and administrative expenses was primarily the result of changes in the classification of certain indirect cost allocations of approximately $30.1 million. These decreases were partially offset by a return to more normalized indirect spending compared to 2020, which experienced reduced travel, conference expenses and other indirect expenses due to the impacts of COVID-19. As a percentage of revenues, general and administrative expenses decreased for the year ended December 31, 2021 as compared to the same period in 2020. We expect general and administrative expenses as a percentage of revenue to increase slightly in 2022, due to higher amortization expenses and continued return to normalized indirect spending.
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 26% and 23% for the years ended December 31, 2021 and 2020, respectively. The increase in our effective tax rate is primarily due to an increase in nondeductible executive equity compensation and a reduced research and development credit. 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, 2020 Compared to Year Ended December 31, 2019
To review the comparison of our results of operations for the fiscal year ended December 31, 2020 with our results of operations for the fiscal year ended December 31, 2019, 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, 2020.
Backlog
For the years ended December 31, 2021 and 2020 our backlog was $10.6 billion and $10.2 billion, respectively, of which $1.6 billion and $1.2 billion, respectively, was funded backlog. The increase in our backlog is due to contract awards and acquisitions during the year. 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
Our primary sources of liquidity are cash provided by operations and our credit facilities. On December 31, 2021, our cash and cash equivalents balance was $53.4 million. There were $300.0 million in outstanding borrowings under our credit facilities at December 31, 2021. The maximum available borrowings under our credit facilities at December 31, 2021 were $796.6 million. These sources of liquidity have met the short-term and long-term liquidity needs for financing of acquisitions, working capital, payment under our cash dividend program and capital expenditures.
Cash provided by operating activities has been adequate to fund our operations, including payments under our regular cash dividend program. When there are short-term fluctuations in our cash flows and level of operations, we may from time-to-time increase borrowings under our credit facilities 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 68 and 56 for the quarters ended December 31, 2021 and 2020, respectively. The increase in DSO is primarily due to increases in accounts receivable from companies acquired in December 2021. For the years ended December 31, 2021 and 2020, our net cash flows from operating activities were $212.2 million and $247.2 million, respectively. The decrease in net cash flows from operating activities during the year ended December 31, 2021 when compared to the same period in 2020 was primarily due to the timing of accrued salaries and related expenses and payment of vendors.
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, 2021 and 2020, our net cash used in investing activities were $425.2 million and $150.1 million, respectively. For the year ended December 31, 2021, our net cash used in investing activities were primarily due to the acquisitions of Gryphon and TMAC as well as the purchase of equipment to support our managed IT service contracts and infrastructure investments. For the year ended December 31, 2020, our net cash used in investing activities were primarily due to the acquisitions of Minerva Engineering and Tapestry Technologies and the purchase of equipment to support our managed IT service contracts and infrastructure investments.
Cash Flows Used in Financing Activities
For the year ended December 31, 2021, our net cash flows from financing activities were $225.2 million, primarily due to net borrowing under our credit facilities to fund acquisitions, offset by dividends paid. For the year ended December 31, 2020, our net cash used in financing activities were $64.8 million, primarily due to dividends paid and net repayments under our revolving credit facility, offset by the proceeds from the exercise of stock options.
Credit Facility
On July 20, 2021, we amended and restated our credit agreement (Third Amended and Restated Credit Agreement) with a syndicate of lenders led by Bank of America, N.A., as sole administrative agent. The Third Amended and Restated Credit Agreement includes an aggregate principal amount of up to $1.1 billion made available through (i) a $500 million revolving credit facility with a $100 million letter of credit sublimit and a $50 million swing line loan sublimit and (ii) a $600 million delayed-draw term loan facility. Under the delayed-draw term loan facility, borrowings are available to be drawn prior to the first anniversary of the Third Amended and Restated Credit Agreement in up to three separate drawings in a minimal amount of $50 million. The Third Amended and Restated Credit Agreement also includes an accordion feature that permits us to arrange with the lenders for the provision of additional commitments. The maturity date of the Third Amended and Restated Credit Agreement is July 20, 2026. We have deferred $3.7 million in debt issuance costs, including $3.3 million due to the Third Amended and Restated Credit Agreement, which are being amortized over the term of the new credit agreement.
Borrowings under the Third Amended and Restated Credit Agreement are collateralized by substantially all of our assets and those of our Material Subsidiaries and bear interest at one of the following variable rates as selected by us at the time of borrowing: a London Interbank Offer Rate base rate plus market-rate spreads (1.25% to 2.00% based on our consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.00% based on our consolidated total leverage ratio).
The terms of the Third Amended and Restated Credit Agreement permit prepayment and termination of the loan commitments at any time, subject to certain conditions. The Third Amended and Restated Credit Agreement requires us to comply with specified financial covenants, including the maintenance of certain leverage ratios and a consolidated coverage ratio. The Third Amended and Restated 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, 2021 and 2020, we were in compliance with our financial covenants under the credit agreement.
There was $300.0 million and $15.0 million outstanding on our credit facilities at December 31, 2021 and 2020, respectively.
Contractual Obligations
Our primary contractual obligations include operating lease obligations and debt obligations. Our operating lease obligations as of December 31, 2021 were $96.1 million. These obligations will be paid within the time period of less than one year to more than 5 years. See Note 5 to our consolidated financial statements in Item 8 for additional information regarding leases. Our debt obligations as of December 31, 2021 were $300.0 million. We may elect to pay all of or a portion of this obligation earlier than contractually required. See Note 9 to our consolidated financial statements in Item 8 for additional information regarding debt and related matters.
Capital Resources
We believe the capital resources available to us from cash on hand, our remaining capacity under our credit facilities, 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 credit facilities; 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, 2021 and 2020, we declared and paid quarterly dividends in the amount of $0.38 and $0.32 per share on both classes of common stock. On February 22, 2022, we declared a quarterly cash dividend in the amount of $0.41 per share, to be paid on March 25, 2022. 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.
Critical Accounting Estimates
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). Our significant accounting policies are described in Note 2 to our consolidated financial statements in Item 8. We consider certain of these policies to be critical accounting policies as they require management to make significant 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.
Revenue Recognition and Cost Estimation
At contract inception, we identify our performance obligations; then we determine the transaction price for 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 as the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price when 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.
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. We also 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.
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. 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 years ended December 31, 2021, 2020 and 2019, the aggregate impact of adjustments in contract estimates increased our revenue by $8.8 million, $10.8 million and $11.3 million, respectively. No adjustment on any one contract was material to our consolidated financial statements for the years ended December 31, 2021, 2020 and 2019.
Estimates in Fair Value of Assets Acquired and Liabilities Assumed in Business Combinations
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.
Estimates in Fair Value of Reporting Units in Goodwill Impairment
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.
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.
Estimates in Accounting for Income Taxes
We account for income taxes in accordance with ASC 740, Income Taxes, as a result our 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
Item 7A.Quantitative and Qualitative Disclosures about Market Risk
Our exposure to market risk relates to changes in interest rates for borrowings under our credit facilities. At December 31, 2021, we had $300.0 million outstanding on our credit facilities. Borrowings under our credit facilities bear interest at variable rates. A hypothetical 10% increase in interest rates would have a $0.1 million effect on our interest expense for the year ended December 31, 2021.
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 stockholders 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, 2021 and 2020, 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, 2021, 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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, 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, 2021, 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 25, 2022, 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.
Revenue from Contracts with Customers - 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 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 4 to the financial statements
Critical Audit Matter Description
During 2021 the Company completed the acquisition of Gryphon Technologies, Inc. (“Gryphon”) for approximately $360.8 million. The Company accounted for the acquisition 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 $71.3 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.
We identified the customer relationship and backlog intangible assets for the Gryphon acquisition as a critical audit matter because of the significant estimates and assumptions management made to determine the fair value of 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.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the forecast of future revenue, earnings and cash flows, and the selection of 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 revenue, earnings and cash flows, and the selection of discount rates.
•We assessed the reasonableness of management’s forecast of future revenue, earnings and 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.

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 our control. 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 it is more likely than not that the fair value of the reporting unit is less than its carry amount, then we will perform the quantitative impairment test (described below). We also may bypass the qualitative assessment for any reporting unit in any period and, proceed directly to perform the quantitative impairment test.
The quantitative goodwill impairment test, is used to identify both the existence of impairment and the amount of the impairment loss, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, the goodwill of the reporting unit is not impaired. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss will be recognized in the amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.
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 1 year to 25 years.
We account for the cost of computer software developed or obtained for internal use in accordance with Accounting Standards Codification (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 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 5 years or other such shorter period as may be required.
Leases - We account for leases in accordance with ASC 842, Leases. Upon adoption, 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 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.
We determine whether 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 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, Accrued expenses and other current liabilities and Other long-term liabilities on our consolidated balance sheets.
Our ROU asset is recognized as the lease obligation, any initial direct 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 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 statements of income.
In our consolidated statements 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 ASC 321-10-35, Investments - Equity Securities. Under this topic, our investment equals our cost, less impairment, if any. For investments without a readily determinable fair value, we perform a qualitative assessment to determine if any impairment indicator is present. If an indicator is present, we estimate the fair value to determine if the fair value was less than its carrying value. If the fair value is less than its carrying value or if there is an observable price change through a similar security from the same issuer, we would record an impairment.
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 contract costs are reported on our consolidated balance sheets within current or non-current other assets based on the expected life of the related contract. At December 31, 2021 and 2020, we had $1.9 million and $6.6 million,
respectively, of deferred contract costs related to the fulfillment of future contract obligations. For the year ended December 31, 2021 and 2020, we recorded amortization expense of $4.7 million and $2.8 million, respectively.
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 - 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 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, 2021, 2020 and 2019 the aggregate impact of adjustments in contract estimates increased our revenue by $8.8 million, $10.8 million and $11.3 million, respectively. No adjustment on any one contract was material to our consolidated financial statements for the year ended December 31, 2021.
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 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 of stock options is recognized as operating expenses or is 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
ASUs adopted during the year ended December 31, 2021 did not have a material impact on our consolidated financial statements.
Recently Issued But Not Yet Adopted ASUs
ASUs effective after December 31, 2021 are not expected to have a material effect on our consolidated financial statements.
3.Revenue from Contracts with Customers
We derive revenue from contracts with customers primarily from contracts with the U.S. government in the areas of intelligence, defense, 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 approximately 100%, 99% and 99% from revenue generated in the U.S. for the years ended December 31, 2021, 2020 and 2019, respectively.
The following tables disclose revenue (in thousands) by contract type, customer and prime or subcontractor for the periods presented.

$ 2,553,956 $ 2,518,384 $ 2,222,559
We deliver a broad array of IT and technical services solutions under contracts with the U.S. government, state and local governments and commercial customers. The components of receivables are as follows (in thousands):
December 31, 2021 December 31, 2020
Billed receivables $ 370,115 $ 312,991
Unbilled receivables 118,387 106,007
Allowance for doubtful accounts (12,467) (18,377)
Receivables-net $ 476,035 $ 400,621
Receivables at December 31, 2021 are expected to be substantially collected within one year except for approximately $1.7 million, of which a majority is related to U.S. government receivables. 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 measure future expected credit losses expected to occur over the estimated life or remaining contractual life of an asset (which includes losses that may be incurred in future periods). When we identify receivables with unique risk characteristics, we evaluate such receivables on an individual basis. A change in our assessment of the creditworthiness and collections from a prime contractor on one of our contracts resulted in a decrease in allowance for doubtful accounts during 2021.
The following table discloses contract liabilities (in thousands):
December 31, 2021 December 31, 2020
Contract liabilities $ 36,197 $ 37,218
Changes in the balance of contract liabilities are primarily due to the timing difference between our performance and our customers' payments. For the year ended December 31, 2021, the amount of revenue that was included in the opening contract liabilities balance was $31.0 million.
The remaining performance obligation at December 31, 2021 was $2.4 billion. The following table discloses when we expect to recognize the remaining performance obligation as revenue (in billions):

4. Acquisitions
Technical and Management Assistance Corporation (TMAC)-On December 30, 2021, we completed the acquisition of TMAC through a share purchase agreement by and among ManTech International Corporation, Technical and Management
Assistance Corporation, Project Cipher, Inc, and its Shareholder. TMAC is a leading provider of advanced data engineering services and solutions that ensure the delivery of vital information to the U.S. Intelligence Community.
The acquisition was accounted for as a business combination. The results of TMAC's operations have been included in our consolidated financial statements since that date. We funded the acquisition with cash on hand.
The preliminary purchase price was $30.2 million, which includes an estimated working capital adjustment. The preliminary purchase price 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 TMAC is not complete as of December 31, 2021. In accordance with ASC 805, Business Combinations, we expect to finalize our purchase price allocation within one year of the acquisition date.
Recognition of goodwill is largely attributed to the value paid for TMAC's capabilities, which will broaden our footprint within the U.S. Intelligence Community. The goodwill recorded for this transaction is valued at $13.2 million and 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 $15.3 million and $0.7 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 TMAC'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 1 year. The weighted-average amortization period of other intangibles is 19 years.
For the year ended December 31, 2021, we incurred approximately $0.4 million of acquisition costs related to the TMAC transaction, which are included in general and administrative expenses in our consolidated statement of income.
Gryphon Technologies, Inc. (Gryphon)-On December 9, 2021, we completed the acquisition of Gryphon through a unit purchase agreement by and among ManTech International Corporation, Gryphon Parent, LLC and Gryphon Finance, LLC. Gryphon will further strengthen our long-term competitive position by adding differentiated digital and systems engineering capabilities across the Department of Defense.
The acquisition was accounted for as a business combination. The results of Gryphon's operations have been included in our consolidated financial statements since that date. We funded the acquisition with cash on hand and borrowing under our credit facilities.
The preliminary purchase price was $360.8 million, which includes an estimated working capital adjustment. The preliminary purchase price 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 Gryphon is not complete as of December 31, 2021. In accordance with ASC 805, Business Combinations, we expect to finalize our purchase price allocation within one year of the acquisition date.
Recognition of goodwill is largely attributed to the value paid for Gryphon's capabilities, which will broaden our footprint within the Department of Defense. Pre-existing goodwill recorded for this transaction will be deductible for tax purposes over 13 years. The remainder of goodwill attributable to the acquisition of Gryphon will not be deductible for tax purposes.
The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $65.8 million and $5.5 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 Gryphon'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 of other intangibles is 19 years.

For the year ended December 31, 2021, we incurred approximately $1.1 million of acquisition costs related to the Gryphon transaction, which are included in general and administrative expenses in our consolidated statement of income.
Tapestry Technologies (Tapestry)-On December 11, 2020, we completed the acquisition of Tapestry through a share purchase agreement by and among ManTech International Corporation, Tapestry Technologies, Inc., Project Tribune Holdings, Inc. (Holdco), and all of the shareholders of the Holdco. Tapestry provides unique insight and cybersecurity solutions to the U.S. Defense Information Systems Agency (DISA) and the Department of Defense (DoD). This acquisition broadens our footprint with DISA, serves as a springboard into the broader Defense Department IT marketspace, and provides us access to well-funded DISA and DoD programs.
The acquisition was accounted for as a business combination. The results of Tapestry's operations have been included in our consolidated financial statements since that date. We funded the acquisition with cash on hand and borrowing under our revolving credit facility.
The purchase price of $46.3 million has been 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 for Tapestry was complete as of December 31, 2021.
Recognition of goodwill is largely attributed to the value paid for Tapestry's capabilities, which will broaden our footprint within DISA and the Defense Department IT marketplace. The goodwill recorded for this transaction is valued at $27.0 million and 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 $15.1 million and $1.4 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 Tapestry'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 of other intangibles is 18 years.
For the year ended December 31, 2020, we incurred approximately $0.1 million of acquisition costs related to the Tapestry transaction, which are included in general and administrative expenses in our consolidated statement of income.
Minerva Engineering (Minerva)-On November 9, 2020, we completed the acquisition of Minerva through a membership interest purchase agreement by and among ManTech International Corporation., Minerva Engineering, LLC and NH Holdco LLC. Minerva is a leading provider of advanced cyber services that support the intelligence community, including risk and vulnerability assessment, incident response and cyber intrusion detection, and wireless signal discovery. This acquisition enhances and expands our cyber defense capabilities within the intelligence community, adding new customers, new past performance qualifications, mission-critical contracts, and highly skilled, cleared professionals that increase our deep cyber security talent base.
The acquisition was accounted for as a business combination. The results of Minerva's operations have been included in our consolidated financial statements since that date. We paid for the acquisition with cash on November 9, 2020 and a short-term promissory note that was paid on November 12, 2020.
The purchase price of $32.7 million includes a finalized working capital adjustment and has been 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 for Minerva was complete as of December 31, 2021.
Recognition of goodwill is largely attributed to the value paid for Minerva's capabilities, which will broaden our footprint within the intelligence community through the addition of differentiated capabilities and access to new customers and contracts. The goodwill recorded for this transaction is valued at $19.8 million and 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 $10.5 million and $1.1 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 Minerva'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 18 years.
For the year ended December 31, 2020, we incurred approximately $0.4 million of acquisition costs related to the Minerva transaction, which are included in general and administrative expenses in our consolidated statement of income.
5. Leases
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).
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 10 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 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, 2021, 2020, and 2019 was $5.2 million, $6.3 million, and $5.4 million, respectively. For the year ended December 31, 2021, 2020, and 2019 we incurred variable lease costs of $3.6 million, $2.7 million, and $2.4 million, respectively.

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, 2021, 2020 and 2019, we declared and paid quarterly dividends, in the amount of $0.38, $0.32 and $0.27 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.
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):

For the years ended December 31, 2021, 2020 and 2019, there were 196,735 shares, 223,405 shares and 338,748 shares, respectively, issued from the exercise of stock options.

9.Debt
On July 20, 2021, we amended and restated our credit agreement (Third Amended and Restated Credit Agreement) with a syndicate of lenders led by Bank of America, N.A., as sole administrative agent. The Third Amended and Restated Credit Agreement includes an aggregate principal amount of up to $1.1 billion made available through (i) a $500 million revolving credit facility with a $100 million letter of credit sublimit and a $50 million swing line loan sublimit and (ii) a $600 million delayed-draw term loan facility. Under the delayed-draw term loan facility, borrowings are available to be drawn prior to the first anniversary of the Third Amended and Restated Credit Agreement in up to three separate drawings in a minimal amount of $50 million. The Third Amended and Restated Credit Agreement also includes an accordion feature that permits us to arrange with the lenders for the provision of additional commitments. The maturity date of the Third Amended and Restated Credit Agreement is July 20, 2026. We have deferred $3.7 million in debt issuance costs, including $3.3 million due to the Third Amended and Restated Credit Agreement, which are being amortized over the term of the new credit agreement.
Borrowings under the Third Amended and Restated Credit Agreement are collateralized by substantially all of our assets
and those of our Material Subsidiaries and bear interest at one of the following variable rates as selected by us at the time of borrowing: a London Interbank Offer Rate base rate plus market-rate spreads (1.25% to 2.00% based on our consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.00% based on our consolidated total leverage ratio). The aggregate annual weighted average interest rates were 1.59% and 2.32% for the years ended December 31, 2021 and 2020, respectively.
The terms of the Third Amended and Restated Credit Agreement permit prepayment and termination of the loan commitments at any time, subject to certain conditions. The Third Amended and Restated Credit Agreement requires us to comply with specified financial covenants, including the maintenance of certain leverage ratios and a consolidated coverage ratio. The Third Amended and Restated 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, 2021 and 2020, we were in compliance with our financial covenants under the credit agreement.
There was $300.0 million and $15.0 million outstanding on our credit facilities at December 31, 2021 and 2020, respectively. The weighted average borrowings under the revolving and term portions of the facilities during the years ended December 31, 2021 and 2020 were $35.3 million and $37.3 million, respectively. The maximum available borrowing under the credit facilities at December 31, 2021 was $796.6 million. At December 31, 2021 and 2020, we had $3.4 million and $6.2 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 2018 with no material adjustments. The remaining audits for 2019 through 2020 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.
We have $3.4 million outstanding on our letter of credit, of which $1.6 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, 2021, there were 27,618,928 shares of Class A common stock outstanding, 244,113 shares of Class A common stock recorded as treasury stock and 13,176,695 shares of Class B common stock outstanding.
Holders of Class A common stock are entitled to one vote for each share held of record and holders of Class B common stock are entitled to ten votes for each share held of record, except with respect to any “going private transaction” (generally, a transaction in which George J. Pedersen (our Chairman Emeritus), 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 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, 2021 and 2020, 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, 2022, there were 611,922 additional shares made available for issuance under the Plan. Through December 31, 2021, the Board of Directors has authorized the issuance of up to 16,358,071 shares under this Plan. Through December 31, 2021, the remaining aggregate number of shares of our common stock available for future grants under the Plan was 7,665,322. 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, 2021, 2020 and 2019, we recorded $15.4 million, $11.4 million and $7.5 million of stock-based compensation expense, respectively. No compensation expense of employees with stock awards was capitalized during the years ended December 31, 2021, 2020 and 2019. For the years ended December 31, 2021, 2020 and 2019, we recorded $2.3 million, $1.6 million and $2.1 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 in the past. 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 issued options that vest over 3 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 8 years. During the year ended December 31, 2019, we issued options that expire 5 years from the date of grant. We did not grant any options during the years ended December 31, 2021 and 2020.
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 year ended December 31, 2019:
•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 3 years in equal installments beginning on the first anniversary of the date of the grant and a contractual term of 5 years.
•Risk-free interest rate - The yield on zero-coupon U.S. Treasury strips was used to extrapolate a forward-yield curve. This “term structure” of future interest rates was then input into a numeric model to provide the equivalent risk-free rate to be used in the Black-Scholes-Merton model based on the expected term of the underlying grants.
•Dividend yield - The Black-Scholes-Merton valuation model requires an expected dividend yield as an input. For the year ended December 31, 2019, we have calculated our expected dividend yield based on an expected annual cash dividend of $1.08 per share.
The following table summarizes weighted-average assumptions used in our calculations of fair value for the year ended December 31, 2019:
Volatility 27.21 %
Expected life of options 3 years
Risk-free interest rate 1.98 %
Dividend yield 1.76 %
Stock Option Activity - The weighted-average fair value of options granted during the year ended December 31, 2019, as determined under the Black-Scholes-Merton valuation model, was $12.07. Option grants that vested during the years ended December 31, 2021, 2020 and 2019 had a combined fair value of $2.5 million, $3.6 million and $2.5 million, respectively.

Unrecognized compensation expense related to outstanding stock options was $0.8 million as of December 31, 2021, which is expected to be recognized over a weighted-average period of one year 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.
Restricted Stock Activity - The following table summarizes the restricted stock activity during the years ended December 31, 2021 and 2020:
Number of Shares Weighted Average Fair Value
Non-vested restricted stock at December 31, 2019 24,000 $ 62.66
Granted 24,000 $ 71.11
Vested (24,000) $ 62.66
Non-vested restricted stock at December 31, 2020 24,000 $ 71.11
Granted 24,000 $ 86.01
Vested (24,000) $ 71.11
Non-vested restricted stock at December 31, 2021 24,000 $ 86.01
RSUs - Under the Plan, we have issued restricted stock units (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 have no voting rights until the RSUs vest. Employees who are granted RSUs do not receive dividend payments during the vesting period. Our employees' time-based RSUs generally provide for 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.
RSU Activity - The following table summarizes the RSU activity during the years ended December 31, 2021 and 2020:
Number of Units Weighted Average Fair Value
RSUs at December 31, 2019 210,827 $ 55.31
Granted 266,880 $ 68.83
Vested (73,047) $ 53.85
Forfeited (57,861) $ 64.52
RSUs at December 31, 2020 346,799 $ 64.48
Granted 236,240 $ 78.78
Vested (152,121) $ 61.06
Forfeited (25,564) $ 67.07
RSUs at December 31, 2021 405,354 $ 73.94
12.Retirement Plans
As of December 31, 2021, 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 $40.4 million, $33.0 million and $26.7 million for the years ended December 31, 2021, 2020 and 2019, respectively.
As of December 31, 2021, we maintained an Employee Supplemental Savings Plan (ESSP), which is a nonqualified deferred compensation plan for certain key employees. Prior to January 1, 2020, eligible employees could defer up to 75% of qualified annual base compensation and 100% of bonus. Beginning in the 2020 plan year, additional deferrals were suspended. Contributions made in 2020 relate to deferrals on bonuses earned in 2019 but paid in 2020. 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. There were no employee contributions for the year ended December 31, 2021. Employee contributions to this plan were approximately $0.5 million and $3.4 million for the years ended December 31, 2020 and 2019, respectively.
We maintained a nonqualified supplemental defined benefit pension plan for certain retired employees of an acquired company as of December 31, 2021. 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, 2021 and 2020, 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 $0.6 million and $0.7 million at December 31, 2021 and 2020, respectively.

Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. A summary of the tax effect of the significant components of deferred income taxes is as follows (in thousands):
December 31,
2021 2020
Goodwill and other intangibles $ 185,811 $ 152,412

Less: Valuation allowance 2,008 1,971
Gross deferred tax assets (53,012) (56,820)
Net deferred tax liabilities $ 174,060 $ 141,638
At December 31, 2021, we had federal, state and foreign net operating losses of approximately $3.5 million, $11.9 million and $1.9 million, respectively. The federal and foreign net operating losses may be carried forward indefinitely. The state net operating losses expire beginning 2028 through 2039. 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):
December 31,
2021 2020 2019
Gross unrecognized tax benefits at beginning of year $ 11,708 $ 9,635 $ 490
Increases in tax positions for current year 1,562 1,712 1,839
Decreases in tax positions for prior years (109) - (412)
Lapse in statute of limitations (27) (10) -
Increases in tax positions for prior years - 371 7,718
Gross unrecognized tax benefits at end of year $ 13,134 $ 11,708 $ 9,635
The total liability for gross unrecognized tax benefits as of December 31, 2021, 2020 and 2019 includes $13.1 million, $11.7 million and $9.6 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 accrued expenses and other current liabilities and other long-term liabilities in our consolidated balance sheet. Interest, which is included in interest expense in our consolidated statement of income, was $0.2 million for the year ended December 31, 2021 and not material for the other years presented.
During the year ended December 31, 2021, we recognized an increase in unrecognized tax benefits of approximately $1.4 million, of which $1.3 million relates to an increase in research and development tax credits available to us. During the year ended December 31, 2020, we recognized an increase in unrecognized tax benefits of approximately $2.1 million of which $1.8 million related to an increase in research and development tax credits available to us. During the year ended December 31, 2019 we recognized an increase in unrecognized tax benefits related to available research and development credits of $7.7 million 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 2016. We are currently under examination by the Internal Revenue Services and various state tax authorities for tax years 2016-2018. We are no longer subject to U.S. state tax examinations by tax authorities for the years before 2016. Given the inherent uncertainty surrounding the on-going IRS examination for tax years 2016-2018, we are unable to reasonably estimate the timing or change in amounts of our unrecognized tax benefits.

ITEM 9A. CONTROLS AND PROCEDURES
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 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, 2021, 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. As permitted by the SEC rules, management's assessment and conclusion on the effectiveness of our internal control over financial reporting as of December 31, 2021, excludes an assessment of the internal control over financial reporting of Gryphon Technologies, acquired on December 9, 2021. The assets of Gryphon Technologies constituted 15% of the Company’s consolidated total assets as of December 31, 2021. 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, 2021, 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, 2021, 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.
