PART I

Overview

For more than 100 years, business, government, and military leaders have turned to Booz Allen Hamilton to solve their most complex problems. A values-driven organization with a guiding purpose to empower people to change the world, we remain focused on providing long-term solutions to our clients’ emerging and ever-changing challenges. Our people are passionate about their service to our clients and their missions and the communities in which we live and work. This is our heritage, and it is as true today as when the Company was founded in 1914.

A collaborative culture is an integral part of our unique operating model, which encourages our people to bring a diversity of ideas and talent to every client engagement. Building on our legacy of passionate client service and guided by our comprehensive Vision 2020 strategy, we blend deep expertise in management consulting with advanced technical capabilities to deliver powerful solutions. By investing in markets, capabilities, and talent and building new business models, including ventures, partnerships, and product offerings, we believe we are creating sustainable quality growth for the Company.

Through our dedication to our clients' missions, and a commitment to evolving our business to address their needs, we have longstanding relationships with our clients, some more than 75 years. We support critical missions for a diverse base of federal government clients, including nearly all of the U.S. government’s cabinet-level departments, as well as increasingly for top-tier commercial and international clients. We support our federal government clients by helping them tackle their most complex and pressing challenges such as protecting soldiers in combat and supporting their families, advancing cyber capabilities, keeping our national infrastructure secure, enabling and enhancing digital services, transforming the healthcare system, and improving governmental efficiency to achieve better outcomes. We serve commercial clients across industries including aerospace, financial services, health and life sciences, energy, and transportation. Our international clients are primarily in the Middle East, and Southeast Asia.

History and Corporate Structure

We were founded in 1914 by Edwin Booz, one of the pioneers of management consulting. In 1940, we began serving the U.S. government by advising the Secretary of the Navy in preparation for World War II. As the needs of our clients have grown more complex, we have expanded beyond our management consulting foundation to develop deep expertise in the fields of analytics, digital solutions, engineering and cyber.

We are organized and operate as a corporation, but sometimes use the term “partner” to refer to our Chief Executive Officer and our Senior and Executive Vice Presidents. The use of the term “partner” reflects our collaborative culture, and is not meant to imply that we operate our Company as, or have any intention to create a legal entity that is, a partnership.

Booz Allen Holding was incorporated in Delaware in May 2008 to serve as the top-level holding company for the consolidated Booz Allen Hamilton U.S. government consulting business. On July 31, 2008, Booz Allen Hamilton completed the separation of its U.S. government consulting business from its legacy commercial and international consulting business, the spin-off of the commercial and international business, and the sale of 100% of its outstanding common stock to Booz Allen Holding, or the Carlyle Acquisition, which was majority owned by The Carlyle Group and certain of its affiliated investment funds, or Carlyle. Our Company is a corporation that is the successor to the U.S. government consulting business of Booz Allen Hamilton following the separation. Between 2013 and 2016, we registered the offering and sale of common stock by Carlyle, and on December 6, 2016, Carlyle disposed of its remaining shares of the Company's Class A Common Stock in a registered secondary offering.

Our Institution and Operating Model

We operate as a single profit/loss center with a single bonus pool for leadership. Our operating model encourages collaboration allowing us to bring a mix of the best talent to every client engagement. Our partnership-style culture provides the operational flexibility necessary to quickly mobilize people and capabilities to react to market changes faster than our competitors. As a result, we can go to market as a whole firm rather than as a collection of individual competing business units or profit centers. Our operating model also encourages and enables continuous investment in the right markets, capabilities, and talent to position the Company for further growth by anticipating what government and commercial clients will need next.

Across all markets, we address our clients’ complex and evolving needs by deploying multifaceted teams with a combination of deep mission understanding, market-leading functional capabilities, consulting talent, and true technical and engineering expertise. These client-facing teams, which are fundamental to our differentiated value proposition, better position us to create market-relevant growth strategies and plan for and meet current, future, and prospective market needs. They also help us identify and deliver against diverse client needs in a more agile manner. Our significant win rates during fiscal 2019 on new and re-competed contracts of 60% and 83%, respectively, as compared to 63% and 87%, respectively, in fiscal 2018 demonstrate the strength of this approach.

Our People

Our ability to deliver lasting value and results to our clients has always been, and continues to be, a product of the strong character, expertise and tremendous passion of our people. Our approximately 26,100 employees work to solve hard problems by making our clients’ missions their own, combining decades of consulting and domain expertise with functional expertise in areas such as analytics, digital solutions, engineering, and cybersecurity. Our talented people are supported by a culture of innovation, diversity, and inclusion.

Our people at a glance:

• 81 partners

• Nearly 29% are veterans, including 18 partners

• Approximately 85% hold bachelor’s degrees; approximately 40% hold master’s degrees; and approximately 3% hold doctoral degrees

• Approximately 66% hold security clearances

We attract and retain the best people by providing them with opportunities to grow, build skills, and be appreciated for their contributions as they work on our clients’ toughest challenges. We continuously invest in elements of our employee value proposition to ensure we remain an employer of choice in a highly competitive talent marketplace. This value proposition creates a virtuous circle in which our employees know they are making a difference while growing their careers, which furthers their commitment to Booz Allen and makes them ambassadors for future talent. Booz Allen has always recognized the importance of our people and culture, and we continue to build on that strong legacy as we support our employees to meet their full potential.

We also foster the spirit of innovation through events, partnerships, programs, and tools that facilitate collaboration to tackle a common challenge or pitch new products and capabilities. It is the diversity of our employees that fuels this innovation and enhances the way we work by bringing a wealth of experiences and expertise to any challenge. We celebrate difference in all forms, building an environment of diversity and inclusion regardless of ethnicity, religion, gender, sexual orientation, age or disability.

The importance we place on our people continues to receive external recognition. For the ninth consecutive year, Booz Allen has received a perfect score on the Corporate Equality Index (CEI), a national benchmarking survey on corporate policies and practices related to LGBTQ workplace equality administered by the Human Rights Campaign Foundation. In addition, for the fourth consecutive year, Booz Allen received a perfect score on the 2018 Disability Equality Index (DEI), and has been named a DEI "Best Place to Work." Vault.com ranked us as #1 in public sector consulting. Fortune named us as one of the World’s Most Admired Companies and Forbes selected us as one of the Best Employers for Women, a Best Management Consulting Firm, and a Best Employer for New Grads in 2018. We have also been honored with industry awards that showcase our employer brand, including "One of the 9 Best Management Consulting Firms" by Business Insider, "Top-Rated Workplace" and #11 ranked "Hottest Company for Job Seekers" by Indeed, "Best for Vets" by Military Times, "Working Mother Top 100", "Best Place to Work for New Dads" by Fatherly, #18 ranked "Best Places to Work in IT" by Computer World and #17 ranked "Largest Global Defense Contractor" by DefenseNews.

Beyond their client work, our people and our Company demonstrate passionate service in their commitment to our country, military, and communities. Our social impact strategy connects people, organizations, and communities with transformational innovation and technological solutions that power human potential and wider social impact in a spirit of passionate service. For example, we support a variety of organizations assisting veterans and military families, including supporting training in cyber and science, technology, engineering, and math (STEM) careers, and providing data analytics and other technology solutions in support of operations. Our partners include United Service Organization (USO) of Metropolitan Washington-Baltimore, the Hiring Our Heroes program of the U.S. Chamber of Commerce, and the Elizabeth Dole Foundation.

In the past year, we issued 465 "dollars for doers" volunteer service grants to approximately 390 nonprofit groups and schools to recognize employees who volunteered more than 40 hours per year to each of these organizations. Employees recorded more than 88,500 total hours of service during the year and donated generously (with donations matched by the firm) to the American Red Cross National Disaster Relief Fund, Team Rubicon, Good360 and the Booz Allen Foundation for disaster response in communities impacted by recent disasters across the United States. We deployed employees to use their technical and consulting skills to help nonprofits solve their biggest problems through pro bono initiatives for organizations such as the Kennedy Center for the Performing Arts, the Mission Continues, and the National Postal Museum.

Purpose and Values. As one of the first organizations in the United States to adopt a formal code of business ethics, we have always believed that doing what’s right and holding ourselves and others accountable is the only way to do business. Our people exemplify our purpose to "empower people to change the world" and live our values:

•Ferocious Integrity: Do right; hold ourselves accountable

•Unflinching Courage: Speak truth to power; maintain convictions; bring bold thinking

•Passionate Service: Embrace the mission; build community through generosity; make meaningful connections; listen and act with empathy

•Collective Ingenuity: Find the biggest problem and solve it; be resourceful and creative; seek to make the biggest difference; harness the power of diversity; be devoted to the team

•Champion’s Heart: Crave being the best; bring joy to the pursuit; learn from failure; compete with passion

Functional Service Offerings

We offer five functional service offerings, which are supported by continued investment and innovation, that drive our capacity to meet market demand today and into the future. We provide a range of technological capabilities that have had an enduring impact for our clients, our people, and the communities where we live and work.

Our functional service offerings are summarized below:

• Consulting focuses on the talent and expertise needed to solve client problems and develop mission-oriented solutions for specific domains, business strategies, human capital, and operations through new and innovative approaches. We help clients boost organizational performance, deploy new technologies in smart ways, and change and streamline processes to achieve better outcomes.

• Analytics focuses on delivering transformational solutions in the areas of decision analytics (including operations research and cost estimation), automation, and data science (including predictive modeling and machine learning) as well as new or emerging areas such as deep learning and artificial intelligence. We pioneer new approaches to apply analytical technology to clients' problems, draft industry-defining publications, and introduce transformative products such as graphics processing unit (GPU) accelerated deep learning software to the market.

• Digital Solutions combines the power of modern systems development techniques and cloud platforms with the power of machine learning to transform customer and mission experiences. We blend in-depth client mission understanding and digital technical expertise with a consultative approach. We develop, design, and implement powerful solutions built on contemporary methodologies and modern architectures. We accelerate clients to open, cloud native environments, where capability can be securely developed and deployed at scale, and effort allocated toward data management challenges is redirected to analysis and insights.

• Engineering delivers engineering services and solutions to define, develop, implement, sustain, and modernize complex physical systems. We leverage mature engineering methodologies to solve our clients' most complex problems. We bring a holistic understanding of client needs and technical strategy as well as policy experts to deliver purpose-fit solutions to problems. Our engineering capabilities include external industry standard certifications (e.g., International Organization for Standardization 90001 and AS9100).

• Cyber focuses on active prevention, detection, and cost effectiveness. Active prevention includes methods of securing platforms and enterprises against cyber attacks. Detection is the instrumentation of networks to provide lead indicators of penetrations. Cost effectiveness includes our integrated engineering capabilities. Our cyber capabilities are rooted in decades of service to the U.S. federal intelligence community and today afford us the opportunity to maintain technical expertise in network security. With decades of mission intelligence combined with the most advanced tools available, we help clients understand the business value of cyber risk management and prepare for future cybersecurity needs with a lens toward efficiency and effectiveness.

Innovation and Solutions

We are developing transformative solutions that build lasting value for our clients and drive focused innovation to seed next generation businesses in the areas of artificial intelligence, immersive technologies, secure mobility, advanced engineering (such as directed energy), and customer-centric modern digital platforms. We are advancing and creating the infrastructure and mechanics for new and disruptive business models by enabling a vibrant innovation culture, bringing a solutions mindset to our marketplace and sales force, and by building the Company’s presence and brand in the external innovation ecosystem. As a gateway to driving innovation, our solutions combine market-prioritized needs with the Company’s capabilities and products.

5

These solutions enhance future revenue opportunities, monetize the firm's intellectual property, and create differentiated business models and sales channels to drive greater value for our clients.

In addition, we are an essential partner in regional innovation communities all over the country. Through our innovation ecosystem, we are focused on solution co-creation and technology scouting, and are physically co-locating, co-creating, mentoring, incubating, contributing, and investing with organizations in Washington, D.C.; Boston, Massachusetts; Austin, Texas; San Francisco, California; and from Seattle, Washington to San Diego, California (the corridor of venture capitalists and digital powerhouses), with hubs in Herndon, Virginia, Laurel, Maryland, and Charleston, South Carolina. We harness next-generation technologies being created in academic, startup, and big technology firms to imagine and incubate new offerings, solutions, and growth for the Company.

Our Long-Term Growth Strategy

Vision 2020 is a comprehensive strategy to transform Booz Allen and create sustainable quality growth for the Company. Fiscal 2019 was the sixth year of implementing the strategy, but its design reaches back to before the government market began to contract in 2011 and 2012. We anticipated the market downturn and set in place a strategy that would allow us to emerge in a strong position vis-à-vis our competitors. Under Vision 2020, we are:

• Moving closer to the center of our clients’ core missions

• Increasing the technical content of our work

• Attracting and retaining superior talent in diverse areas of expertise

• Leveraging innovation to deliver complex, differentiated, end-to-end solutions

• Creating a broad network of external partners and alliances

• Expanding into the commercial and international markets

The success of our strategy can be seen in:

• Backlog growth, which achieved record levels during fiscal 2019

• Headcount growth and a corresponding shift in our talent portfolio to more technical expertise in disciplines such as systems development, cyber, and analytics

• Continued growth in the global commercial market

• Execution against our capability focused acquisition strategy.

To support our success against our Vision 2020 long-term strategy, we are considering and have taken steps in preparation for the implementation of new financial management systems to, among other things, support business growth and facilitate the exploration of new lines of business in the future.

Our Clients

Booz Allen is committed to solving our clients’ toughest challenges, and we work with a diverse base of public and private sector clients across a number of industries, in the U.S. and internationally.

Our clients call us to work on their hardest problems, such as delivering effective healthcare, protecting soldiers in combat and their families, and keeping our national infrastructure secure. We are investing in markets, capabilities, and talent and are building new business models through strategic ventures, partnerships, and product offerings.

Our government clients include substantially all of the cabinet-level departments of the U.S government. We serve commercial clients across industries including financial services, health and life sciences, energy, and transportation to solve their hardest and most sophisticated challenges, including cybersecurity challenges, and have a thriving portfolio of international clients in the Middle East and Southeast Asia.

A Large Addressable Market

We believe that the U.S government is the world’s largest consumer of management and technology consulting services. The U.S. government’s total spending for its fiscal year ended September 30, 2018 was close to $4.1 trillion, excluding authorizations from Overseas Contingency Operations and supplemental funding for the Department of Defense. Of this amount, approximately $1.4 trillion was for discretionary budget authority, including $701 billion for the Department of Defense and intelligence community and $722 billion for civil agencies. Based on data from the Federal Procurement Data System, approximately $555 billion of the U.S. government’s fiscal year 2018 discretionary outlays were non-intelligence agency funding-related products and services procured from private contractors. We estimate that $137.3 billion of the spending

6

directed toward private contractors in U.S. government fiscal year 2018 was for management, technology, and engineering services, with $76.3 billion spent by the Department of Defense and $61.0 billion spent by civil agencies. The agencies of the U.S. intelligence community that we serve represent an additional market. These numbers also exclude a large addressable market for our services and capabilities in the global commercial markets where we have a modest but growing footprint.

Highlights of Booz Allen’s fiscal 2019 are as follows:

• We derived 96% of our revenue from contracts where the end client was an agency or department of the U.S. government.

• We delivered services under 4,709 contracts and task orders.

• We derived 92% of our revenue in fiscal 2019 from engagements for which we acted as the prime contractor.

• We derived 13% of our revenue in fiscal 2019 from the Navy Marine Corps, which was the single largest client that we served in that year.

Defense and Intelligence Clients

We help our military services take on new missions, tackle acquisition and budgeting challenges, and address the medical needs of soldiers in combat. We also help our defense and intelligence clients adopt innovative technologies by bringing tools, techniques, and expertise to challenges and applying them in innovative ways.

The men and women we hire have served their country and have the experience and determination to help our defense clients keep our nation safe. Our technologists and innovators work alongside our experts in strategy development, acquisition, and operations to help commanders and their staffs in the field share mission-critical information and make crucial battlefield decisions.

We count among our many defense and intelligence clients all four branches of the U.S. military, the Office of the Secretary of Defense, the Joint Staff and members of the intelligence community. Our key defense clients include the Army, Navy/Marine Corps, Air Force, and Joint Combatant Commands. Our key intelligence clients include U.S. intelligence agencies, such as the National Security Agency, National Geospatial-Intelligence Agency, and National Reconnaissance Office, and military intelligence agencies, such as the Defense Intelligence Agency, Service Intelligence Centers, and Intelligence Surveillance Reconnaissance units.

Revenue generated from defense clients was $3.1 billion, or approximately 46.6% of our revenue in fiscal 2019 as compared to $2.8 billion, or approximately 45.9% of our revenue in fiscal 2018. Revenue generated from defense clients also includes foreign military sales to non-U.S. government clients. Revenue generated from intelligence clients was $1.6 billion, or approximately 23.4% of our revenue in fiscal 2019 as compared to $1.5 billion, or approximately 24.2% of our revenue in fiscal 2018.

Civil Clients

Whether ensuring the safety, security, and well-being of citizens, or boosting national competitiveness, we work with leaders in civil government to support their public service missions. We excel at tackling the most complex challenges from reforming financial regulatory oversight and evolving our healthcare system to improving information sharing among law enforcement organizations and supporting green building initiatives.

We work with leaders so they make better decisions and foster better user experiences both inside and outside of their organizations.

Our work spans the full breadth of civil government, including energy and the environment, financial services, health, homeland security, law enforcement, transportation, grants, international development and diplomacy, and benefits and entitlements. Our major civil government clients include the Departments of Homeland Security, Health and Human Services, Veterans Affairs, Treasury, and Justice.

Revenue generated from civil government was $1.8 billion, or approximately 26.3% of our revenue in fiscal 2019 as compared to $1.6 billion, or approximately 26.7% of our revenue in fiscal 2018.

Global commercial clients are comprised of U.S. commercial and international clients.

For our commercial clients, we combine our consulting heritage with cybersecurity practitioner experience gained from cyber incidents and challenges in the public and private sectors to deliver market-leading cyber defense solutions that include consulting and managed service. We serve commercial clients in a variety of industries including aerospace, financial services, health and life sciences, and energy and transportation.

For our international clients, we work alongside public and private sector leaders to help shape and execute their critical agendas.

Following the 2011 expiration of our non-competition agreement with our spun-off commercial business, we re-entered the Middle East and North Africa (MENA) and Southeast Asia (SEA) markets. We originally established our international offices located in MENA more than six decades ago and our offices in SEA more than three decades ago. Since re-entering these markets, our strategy and technology consultants have empowered our clients in these regions with the knowledge and experience they need to build their own local resources and capabilities.

Revenue generated from global commercial clients was $261.6 million, or approximately 3.8% of our revenue in fiscal 2019 as compared to $198.1 million, or approximately 3.2% of our revenue in fiscal 2018.

Contracts

Booz Allen’s approach has long been to ensure that we have prime or subcontractor positions on a wide range of contracts that allow clients maximum opportunity to access our services. Our diverse contract base provides stability to our business. This diversity shows that more than 74% of our revenue for fiscal 2019 was derived from 3,610 active task orders under indefinite delivery/indefinite quantity (IDIQ) contract vehicles. Our top IDIQ contract vehicle represented approximately 8.3% of our revenue in fiscal 2019. Our largest task order under an IDIQ contract vehicle accounted for approximately 3.8% of our revenue in fiscal 2019. Our largest definite contract represented approximately 2.8% of our revenue in fiscal 2019.

The U.S. government procures services through two predominant contracting methods: indefinite contract vehicles and definite contracts. Each of these is described below:

• Indefinite contract vehicles provide for the issuance by the client of orders for services or products under the terms of the contract. Indefinite contracts are often referred to as contract vehicles or ordering contracts. IDIQ contracts may be awarded to one contractor (single award) or several contractors (multiple award). Under a multiple award IDIQ contract, there is no guarantee of work as contract holders must compete for individual work orders. IDIQ contracts will often include pre-established labor categories and rates, and the ordering process is streamlined (usually taking less than a month from recognition of a need to an established order with a contractor). IDIQ contracts often have multiyear terms and unfunded ceiling amounts, thereby enabling but not committing the U.S. government to purchase substantial amounts of products and services from one or more contractors in a streamlined procurement process.

• Definite contracts call for the performance of specified services or the delivery of specified products. The U.S. government procures services and solutions through single award, definite contracts that specify the scope of services that will be delivered and identify the contractor that will provide the specified services. When an agency recognizes a need for services or products, it develops an acquisition plan, which details how it will procure those services or products. During the acquisition process, the agency may release a request for information to determine if qualified bidders exist, a draft request for a proposal to allow the industry to comment on the scope of work and

8

acquisition strategy, and finally a formal request for a proposal. Following the evaluation of submitted proposals, the agency will award the contract to the winning bidder.

Listed below are our top IDIQ contracts for fiscal 2019 and the number of active task orders under these contracts as of March 31, 2019. 

	Fiscal 2019 Revenue		% of Total Revenue		Number of Task Orders as of March 31, 2019	Expiration Date (1)

(1) Expiration date applies to the IDIQ vehicle. Task orders awarded under the IDIQ can run past the expiration of the IDIQ itself.

Under their Category Management initiative, the General Services Administration (GSA) has undertaken an effort to improve its professional service schedule offerings. As a result of this initiative, GSA consolidated multiple contract vehicles under the schedule program. The result for Booz Allen has been the consolidation of the scope of six schedules into one professional services schedule contract. The GSA Schedule contracts to be consolidated under the new professional services schedule are: Advertising and Integrated Marketing Solutions (AIMS), Environmental Services (ES), Financial and Business Services (FABS), Logistics Worldwide (LOGWORLD), Mission Oriented Business Integrated Services (MOBIS), and Professional Engineering Services (PES).

Booz Allen’s migration request was accepted in October 2015 and, as a result, our individual schedules included in the GSA’s consolidation will remain in place through the end of the current option period of each individual contract to prevent the interruption of services. The revenue generated under these individual schedules will begin to decrease during this transition period. We anticipate that the decrease in revenue on the individual schedules will be offset by growth under the new professional service schedule. We anticipate this transition will have negligible impact on future revenues.

Listed below for each specified revenue band is the number of task orders, revenue derived from the task orders, and average duration of the task orders as of March 31, 2019. The table includes revenue earned during fiscal 2019 under all task orders that were active during fiscal 2019 under these IDIQ contracts and the number of active task orders on which this revenue was earned. Average duration reflected in the table below is calculated based on the inception date of the task order, which may be prior to the beginning of fiscal 2019, and the completion date which may have been prior or subsequent to March 31, 2019. As a result, the actual average remaining duration for task orders included in this table may be less than the average duration shown in the table, and task orders included in the table may have been complete on March 31, 2019.

Backlog

We define backlog to include the following three components:

• Funded Backlog. Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts.

• Unfunded Backlog. Unfunded backlog represents the revenue value of orders (including optional orders) for services under existing contracts for which funding has not been appropriated or otherwise authorized.

• Priced Options. Priced contract options represent 100% of the revenue value of all future contract option periods under existing contracts that may be exercised at our clients’ option and for which funding has not been appropriated or otherwise authorized.

Our backlog does not include contracts that have been awarded but are currently under protest and also does not include any task orders under IDIQ contracts except to the extent that task orders have been awarded to us under those contracts.

The following table summarizes the value of our contract backlog as of the respective dates presented:

	As of March 31,
	2019		2018
	(In millions)
Funded	$	3,436	$	2,685
Unfunded	3,687		4,161
Priced options	12,198		9,174
Total backlog	$	19,321	$	16,020

We may never realize all of the revenue that is included in our total backlog, and there is a higher degree of risk in this regard with respect to unfunded backlog and priced options. See “Item 7. Management’s Discussion and Analysis of Financial

10

Condition and Results of Operations — Factors and Trends Affecting Our Results of Operations — Sources of Revenue—Contract Backlog” for additional disclosure regarding our backlog. See also “Item 1A. Risk Factors—Risks Related to Our Business—We may not realize the full value of our backlog, which may result in lower than expected revenue.”

Competition

The government services market is highly fragmented and competition within the government professional services industry has intensified as a result of market pressure and consolidation activity. In addition to professional service companies like ours that focus principally on the provision of services to the U.S. government, other companies active in our markets include large defense contractors; diversified consulting, technology, and outsourcing service providers; and small businesses.

Changing government policies and market dynamics are impacting the competitive landscape. In the past, the government’s focus on organizational conflicts of interest have driven divestitures, which have changed the competitive landscape. More recently, there has been increasing pressure from government clients to utilize small businesses, in large part because of a push by both past and present administrations to bolster the economy by helping small business owners. Finally, as a result of the foregoing factors and the drive in our markets to quickly build competencies in growth areas and achieve economies of scale, we believe that consolidation activity among market participants will continue.

In the course of doing business, we compete and collaborate with companies of all types and sizes. We strive to maintain positive and productive relationships with these organizations. Some of them hire us as a subcontractor, and we hire some of them to work with us as our subcontractors. Our major competitors include: (1) contractors focused principally on the provision of services to the U.S. government, (2) large defense contractors that provide both products and services to the U.S. government, and (3) diversified service providers. We compete based on our technical expertise and client knowledge, our ability to successfully recruit and retain appropriately skilled and experienced talent, our ability to deliver cost-effective multifaceted services in a timely manner, our reputation and relationship with our clients, our past performance, security clearances, and the size and scale of our Company. In addition, to maintain our competitive position, we routinely review our operating structure, capabilities, and strategy to determine whether we are effectively meeting the needs of existing clients, effectively responding to developments in our markets, and successfully building a platform intended to provide the foundation for the future growth of our business.

Patents and Proprietary Information

Our management and technology consulting services business utilizes a variety of proprietary rights in delivering products and services to our clients. We claim a proprietary interest in certain service offerings, products, software tools, methodologies, and know-how and also have certain licenses to third-party intellectual property that may be significant to our business. While we have several patents issued and pending in the United States and in certain foreign countries, we do not consider our overall business to be materially dependent on the protection of such patents. In addition, we have a number of trade secrets that contribute to our success and competitive position, and we endeavor to protect this proprietary information. While protecting trade secrets and proprietary information is important, we are not materially dependent on any specific trade secret or group of trade secrets.

We rely on a combination of nondisclosure agreements and other contractual arrangements, as well as copyright, trademark, patent, and trade secret laws to protect our proprietary information. We also enter into proprietary information and intellectual property agreements with employees, which require them to disclose any inventions created during employment, to convey such rights to inventions to us, and to restrict any disclosure of proprietary information. We have a variety of proprietary marks registered in the United States and certain foreign countries, including "Booz Allen Hamilton." Generally, registered trademarks have perpetual life, provided that they are renewed on a timely basis and continue to be used properly as trademarks. We have registered trademarks related to our name and logo in the United States, with the earliest renewal in March 2020, while the earliest renewal for our trademarks outside of the United States is June 2019.

For our work under U.S. government funded contracts and subcontracts, the U.S. government obtains certain rights to data, software, and related information developed under such contracts or subcontracts. These rights generally allow the U.S. government to disclose such data, software, and related information to third parties, which may include our competitors in some instances. In the case of our work as a subcontractor, our prime contractor may also have certain rights to data, information, and products we develop under the subcontract.

Booz Allen Hamiltonand other trademarks or service marks of Booz Allen Hamilton Inc. appearing in this Annual Report are the trademarks or registered trademarks of Booz Allen Hamilton Inc. Trade names, trademarks, and service marks of other companies appearing in this Annual Report are the property of their respective owners.

Regulation

As a contractor to the U.S. government, as well as state and local governments, we are heavily regulated in most fields in which we operate. We deal with numerous U.S. government agencies and entities, and, when working with these and other entities, we must comply with and are affected by unique laws and regulations relating to the formation, administration, and performance of public government contracts. Some significant laws and regulations that affect us include the following:

• the Federal Acquisition Regulation (the "FAR"), and agency regulations supplemental to the FAR, which regulate the formation, administration, and performance of U.S. government contracts. For example, FAR 52.203-13 requires contractors to establish a Code of Business Ethics and Conduct, implement a comprehensive internal control system, and report to the government when the contractor has credible evidence that a principal, employee, agent, or subcontractor, in connection with a government contract, has violated certain federal criminal laws, violated the civil False Claims Act, or has received a significant overpayment;

• the False Claims Act, which imposes civil and criminal liability for violations, including substantial monetary penalties, for, among other things, presenting false or fraudulent claims for payments or approval;

• the False Statements Act, which imposes civil and criminal liability for making false statements to the U.S. government;

• the Truthful Cost or Pricing Data Statute (formerly known as the Truth in Negotiations Act), which requires certification and disclosure of cost and pricing data in connection with the negotiation of certain contracts, modifications, or task orders;

• the Procurement Integrity Act, which regulates access to competitor bid and proposal information and certain internal government procurement sensitive information, and our ability to provide compensation to certain former government procurement officials;

• laws and regulations restricting the ability of a contractor to provide gifts or gratuities to employees of the U.S. government;

• post-government employment laws and regulations, which restrict the ability of a contractor to recruit and hire current employees of the U.S. government and deploy former employees of the U.S. government;

• laws, regulations, and executive orders restricting the handling, use and dissemination of information classified for national security purposes or determined to be “controlled unclassified information” or “for official use only” and the export of certain products, services, and technical data, including requirements regarding any applicable licensing of our employees involved in such work;

• laws, regulations, and executive orders, regulating the handling, use, and dissemination of personally identifiable information in the course of performing a U.S. government contract;

• international trade compliance laws, regulations and executive orders that prohibit business with certain sanctioned entities and require authorization for certain exports or imports in order to protect national security and global stability;

• laws, regulations, and executive orders governing organizational conflicts of interest that may restrict our ability to compete for certain U.S. government contracts because of the work that we currently perform for the U.S. government or may require that we take measures such as firewalling off certain employees or restricting their future work activities due to the current work that they perform under a U.S. government contract;

• laws, regulations and executive orders that impose requirements on us to ensure compliance with requirements and protect the government from risks related to our supply chain;

• laws, regulations and mandatory contract provisions providing protections to employees or subcontractors seeking to report alleged fraud, waste, and abuse related to a government contract;

• the Contractor Business Systems rule, which authorizes Department of Defense agencies to withhold a portion of our payments if we are determined to have a significant deficiency in our accounting, cost estimating, purchasing, earned value management, material management and accounting, and/or property management system; and

• the Cost Accounting Standards and Cost Principles, which impose accounting and allowability requirements that govern our right to reimbursement under certain cost-based U.S. government contracts and require consistency of accounting practices over time.

Given the magnitude of our revenue derived from contracts with the Department of Defense, the Defense Contract Audit Agency, or DCAA, is our cognizant government audit agency. The DCAA audits the adequacy of our internal control systems

12

and policies including, among other areas, compensation. The Defense Contract Management Agency (DCMA), as our cognizant government contract management agency, may determine that a portion of our employee compensation is unallowable based on the findings and recommendations in the DCAA's audits. In addition, the DCMA directly reviews the adequacy of certain other business systems, such as our purchasing system. See “Item 1A. Risk Factors — Risk Related to Our Industry — Our work with government clients exposes us to additional risks inherent in the government contracting environment, which could reduce our revenue, disrupt our business, or otherwise materially adversely affect our results of operations.” We are also subject to audit by Inspectors General of other U.S. government agencies.

The U.S. government may revise its procurement practices or adopt new contract rules and regulations at any time. To help ensure compliance with these laws and regulations, all of our employees are required to attend ethics training at least annually, and to participate in other compliance training relevant to their position. Internationally, we are subject to special U.S. government laws and regulations (such as the Foreign Corrupt Practices Act), local government regulations and procurement policies and practices, including regulations relating to import-export control, investments, exchange controls, and repatriation of earnings, as well as varying currency, political, and economic risks.

U.S. government contracts are, by their terms, subject to termination by the U.S. government either for its convenience or default by the contractor. In addition, U.S. government contracts are conditioned upon the continuing availability of Congressional appropriations. Congress usually appropriates funds for a given program on a September 30 fiscal year basis, even though contract performance could take many years. As is common in the industry, our Company is subject to business risks, including changes in governmental appropriations, national defense policies, service modernization plans, and availability of funds. Any of these factors could materially adversely affect our Company’s business with the U.S. government in the future.

The U.S. government has a broad range of actions that it can instigate to enforce its procurement law and policies. These include proposing a contractor, certain of its operations or individual employees for debarment or suspending or debarring a contractor, certain of its operations or individual employees from future government business. In addition to criminal, civil and administrative actions by the U.S. government, under the False Claims Act, an individual alleging fraud related to payments under a U.S. government contract or program may file a qui tam lawsuit on behalf of the government against us; if successful in obtaining a judgment or settlement, the individual filing the suit may receive up to 30% of the amount recovered by the government.

See “Item 1A. Risk Factors—Risks Related to Our Business—We are required to comply with numerous laws and regulations, some of which are highly complex, and our failure to comply could result in fines or civil or criminal penalties or suspension or debarment by the U.S. government that could result in our inability to continue to work on or receive U.S. government contracts, which could materially and adversely affect our results of operations.”

Item 1A. Risk Factors

You should consider and read carefully all of the risks and uncertainties described below, as well as other information included in this Annual Report, including our consolidated financial statements and related notes. The risks described below are not the only ones facing us. The occurrence of any of the following risks or additional risks and uncertainties not presently known to us or that we currently believe to be immaterial could materially and adversely affect our business, financial condition, and results of operations. This Annual Report also contains forward-looking statements and estimates that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of specific factors, including the risks and uncertainties described below.

Risks Related to Our Business

We depend on contracts with U.S. government agencies for substantially all of our revenue. If our relationships with such agencies are harmed, our future revenue and operating profits would decline.

13

The U.S. government is our primary client, with revenue from contracts and task orders, either as a prime or a subcontractor, with U.S. government agencies accounting for 96% of our revenue for fiscal 2019. Our belief is that the successful future growth of our business will continue to depend primarily on our ability to be awarded work under U.S. government contracts, as we expect this will be the primary source of substantially all of our revenue in the foreseeable future. For this reason, any issue that compromises our relationship with the U.S. government generally or any U.S. government agency that we serve would cause our revenue to decline. Among the key factors in maintaining our relationship with U.S. government agencies are our performance on contracts and task orders, the strength of our professional reputation, compliance with applicable laws and regulations, and the strength of our relationships with client personnel. In addition, the mishandling or the perception of mishandling of sensitive information, such as our failure to maintain the confidentiality of the existence of our business relationships with certain of our clients, including as a result of misconduct or other improper activities by our employees or subcontractors, or a failure to maintain adequate protection against security breaches, including those resulting from cyber attacks, could harm our relationship with U.S. government agencies. See "—Our employees or subcontractors may engage in misconduct or other improper activities, which could harm our ability to conduct business with U.S. government." Our relationship with the U.S. government could also be damaged as a result of an agency’s dissatisfaction with work performed by us, a subcontractor, or other third parties who provide services or products for a specific project for any reason, including due to perceived or actual deficiencies in the performance or quality of our work, and we may incur additional costs to address any such situation and the profitability of that work might be impaired. Further, negative publicity concerning government contractors in general or us in particular may harm our reputation with federal government contractors. To the extent our reputation or relationships with U.S. government agencies is impaired, our revenue and operating profits could materially decline.

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

Our business depends upon continued U.S. government expenditures on defense, intelligence, and civil programs for which we provide support. These expenditures have not remained constant over time, have been reduced in certain periods and, recently, have been affected by the U.S. government’s efforts to improve efficiency and reduce costs affecting federal government programs generally. Our business, prospects, financial condition, or operating results could be materially harmed, among other causes, by the following:

• budgetary constraints, including Congressionally mandated automatic spending cuts, affecting U.S. government spending generally, or specific agencies in particular, and changes in available funding;

• a shift in expenditures away from agencies or programs that we support;

• reduced U.S. government outsourcing of functions that we are currently contracted to provide, including as a result of increased insourcing by various U.S. government agencies due to changes in the definition of “inherently governmental” work, including proposals to limit contractor access to sensitive or classified information and work assignments;

• further efforts to improve efficiency and reduce costs affecting federal government programs;

• changes or delays in U.S. government programs that we support or related requirements;

• a continuation of recent efforts by the U.S. government to decrease spending for management support service contracts;

• U.S. government shutdowns due to, among other reasons, a failure by elected officials to fund the government (such as that which occurred during government fiscal years 2014, 2018 and 2019) or weather-related closures in the Washington, D.C. area and other potential delays in the appropriations process;

• U.S. government agencies awarding contracts on a technically acceptable/lowest cost basis in order to reduce expenditures;

• delays in the payment of our invoices by government payment offices;

• an inability by the U.S. government to fund its operations as a result of a failure to increase the federal government’s debt ceiling, a credit downgrade of U.S. government obligations or for any other reason; and

• changes in the political climate and general economic conditions, including a slowdown of the economy or unstable economic conditions and responses to conditions, such as emergency spending, that reduce funds available for other government priorities.

In addition, any disruption in the functioning of U.S. government agencies, including as a result of U.S. government closures and shutdowns, terrorism, war, natural disasters, destruction of U.S. government facilities, and other potential

14

calamities could have a negative impact on our operations and cause us to lose revenue or incur additional costs due to, among other things, our inability to deploy our staff to client locations or facilities as a result of such disruptions.

The U.S. government budget deficits, the national debt, and prevailing economic conditions, and actions taken to address them, could negatively affect U.S. government expenditures on defense, intelligence, and civil programs for which we provide support. The Department of Defense is one of our significant clients and cost cutting, including through consolidation and elimination of duplicative organizations and insourcing, has become a major initiative for the Department of Defense. In particular, the Budget Control Act of 2011 (as subsequently amended) provides for automatic spending cuts (referred to as sequestration) totaling approximately $1.2 trillion between 2013 and 2021, including an estimated $500 billion in federal defense spending cuts over this time period. Most recently, the Bipartisan Budget Act of 2018 amended the discretionary spending limits established by the Budget Control Act of 2011, as amended, for the government fiscal 2018 and 2019 budgets across the federal government and increased the prior discretionary spending cap in both defense and non-defense. Pursuant to the Department of Defense and Labor, Health and Human Services, and Education Appropriations Act, 2019 and Consolidated Appropriations Act, 2019, the new Department of Defense spending limit is approximately $674.4 billion for government fiscal 2019, including an allocation of $67.9 billion in overseas contingency operations funding. While recent budget actions reflect a more measured and strategic approach to addressing the U.S. government’s fiscal challenges, there remains uncertainty as to how exactly budget cuts, including sequestration, will impact us, and we are therefore unable to predict the extent of the impact of such cuts on our business and results of operations. However, a reduction in the amount of or reductions, delays, or cancellations of funding for, services that we are contracted to provide to the Department of Defense as a result of any of these related initiatives, legislation or otherwise could have a material adverse effect on our business and results of operations. In addition, in response to an Office of Management and Budget mandate, government agencies have reduced management support services spending in recent years. If federal awards for management support services continue to decline, our revenue and operating profits may materially decline and further efforts by the Office of Management and Budget to decrease federal awards for management support services could have a material and adverse effect on our business and results of operations.

These or other factors could cause our defense, intelligence, or civil clients to decrease the number of new contracts awarded generally and fail to award us new contracts, reduce their purchases under our existing contracts, exercise their right to terminate our contracts, or not exercise options to renew our contracts, any of which could cause a material decline in our revenue.

We are required to comply with numerous laws and regulations, some of which are highly complex, and our failure to comply could result in fines or civil or criminal penalties or suspension or debarment by the U.S. government that could result in our inability to continue to work on or receive U.S. government contracts, which could materially and adversely affect our results of operations.

As a U.S. government contractor, we must comply with laws and regulations relating to the formation, administration, and performance of U.S. government contracts, which affect how we do business with our clients. Such laws and regulations may potentially impose added costs on our business and our failure to comply with them may lead to civil or criminal penalties, termination of our U.S. government contracts, and/or suspension or debarment from contracting with federal agencies. Some significant laws and regulations that affect us include:

• the FAR, and agency regulations supplemental to the FAR, which regulate the formation, administration, and performance of U.S. government contracts. For example, FAR 52.203-13 requires contractors to establish a Code of Business Ethics and Conduct, implement a comprehensive internal control system, and report to the government when the contractor has credible evidence that a principal, employee, agent, or subcontractor, in connection with a government contract, has violated certain federal criminal laws, violated the civil False Claims Act, or has received a significant overpayment;

• the False Claims Act, which imposes civil and criminal liability for violations, including substantial monetary penalties, for, among other things, presenting false or fraudulent claims for payments or approval;

• the False Statements Act, which imposes civil and criminal liability for making false statements to the U.S. government;

• the Truthful Cost or Pricing Data Statute (formerly known as the Truth in Negotiations Act), which requires certification and disclosure of cost and pricing data in connection with the negotiation of certain contracts, modifications, or task orders;

• the Procurement Integrity Act, which regulates access to competitor bid and proposal information and certain internal government procurement sensitive information, and our ability to provide compensation to certain former government procurement officials;

• laws and regulations restricting the ability of a contractor to provide gifts or gratuities to employees of the U.S. government;

15

• post-government employment laws and regulations, which restrict the ability of a contractor to recruit and hire current employees of the U.S. government and deploy former employees of the U.S. government;

• laws, regulations, and executive orders restricting the handling, use and dissemination of information classified for national security purposes or determined to be “controlled unclassified information” or “for official use only” and the export of certain products, services, and technical data, including requirements regarding any applicable licensing of our employees involved in such work;

• laws, regulations, and executive orders regulating the handling, use, and dissemination of personally identifiable information in the course of performing a U.S. government contract;

• international trade compliance laws, regulations and executive orders that prohibit business with certain sanctioned entities and require authorization for certain exports or imports in order to protect national security and global stability;

• laws, regulations, and executive orders governing organizational conflicts of interest that may restrict our ability to compete for certain U.S. government contracts because of the work that we currently perform for the U.S. government or may require that we take measures such as firewalling off certain employees or restricting their future work activities due to the current work that they perform under a U.S. government contract;

• laws, regulations and executive orders that impose requirements on us to ensure compliance with requirements and protect the government from risks related to our supply chain;

• laws, regulations and mandatory contract provisions providing protections to employees or subcontractors seeking to report alleged fraud, waste, and abuse related to a government contract;

• the Contractor Business Systems rule, which authorizes Department of Defense agencies to withhold a portion of our payments if we are determined to have a significant deficiency in our accounting, cost estimating, purchasing, earned value management, material management and accounting, and/or property management system; and

• the FAR Cost Accounting Standards and Cost Principles, which impose accounting and allowability requirements that govern our right to reimbursement under certain cost-based U.S. government contracts and require consistency of accounting practices over time.

In addition, the U.S. government adopts new laws, rules, and regulations from time to time that could have a material impact on our results of operations. Adverse developments in legal or regulatory proceedings on matters relating to, among other things, cost accounting practices and compliance, contract interpretations and statute of limitations, could also result in materially adverse judgments, settlements, withheld payments, penalties, or other unfavorable outcomes.

Our performance under our U.S. government contracts and our compliance with the terms of those contracts and applicable laws and regulations are subject to periodic audit, review, and investigation by various agencies of the U.S. government and the current environment has led to increased regulatory scrutiny and sanctions for non-compliance by such agencies generally. In addition, from time to time we report potential or actual violations of applicable laws and regulations to the relevant governmental authority. Any such report of a potential or actual violation of applicable laws or regulations could lead to an audit, review, or investigation by the relevant agencies of the U.S. government. If such an audit, review, or investigation uncovers a violation of a law or regulation, or improper or illegal activities relating to our U.S. government contracts, we may be subject to civil or criminal penalties or administrative sanctions, including the termination of contracts, forfeiture of profits, the triggering of price reduction clauses, withholding of payments, suspension of payments, fines and suspension, or debarment from contracting with U.S. government agencies. Such penalties and sanctions are not uncommon in the industry and there is inherent uncertainty as to the outcome of any particular audit, review, or investigation. If we incur a material penalty or administrative sanction or otherwise suffer harm to our reputation, our profitability, cash position, and future prospects could be materially and adversely affected.

Further, if the U.S. government were to initiate suspension or debarment proceedings against us or if we are indicted for or convicted of illegal activities relating to our U.S. government contracts following an audit, review, or investigation, we may lose our ability to be awarded contracts in the future or receive renewals of existing contracts for a period of time which could materially and adversely affect our results of operations or financial condition. We could also suffer harm to our reputation if allegations of impropriety were made against us, which would impair our ability to win awards of contracts in the future or receive renewals of existing contracts. See "Item 1. Business — Regulation."

We derive a majority of our revenue from contracts awarded through a competitive bidding process, and our revenue and profitability may be adversely affected if we are unable to compete effectively in the process or if there are delays caused by our competitors protesting major contract awards received by us.

We derive a majority of our revenue from U.S. government contracts awarded through competitive bidding processes. We do not expect this to change for the foreseeable future. Our failure to compete effectively in this procurement environment would have a material adverse effect on our revenue and profitability.

The competitive bidding process involves risk and significant costs to businesses operating in this environment, including:

• the necessity to expend resources, make financial commitments (such as procuring leased premises) and bid on engagements in advance of the completion of their design, which may result in unforeseen difficulties in execution, cost overruns and, in the case of an unsuccessful competition, the loss of committed costs;

• the substantial cost and managerial time and effort spent to prepare bids and proposals for contracts that may not be awarded to us;

• the ability to accurately estimate the resources and costs that will be required to service any contract we are awarded;

• the expense and delay that may arise if our competitors protest or challenge contract awards made to us pursuant to competitive bidding, and the risk that any such protest or challenge could result in the resubmission of bids on modified specifications, or in termination, reduction, or modification of the awarded contract; and

• any opportunity cost of not bidding and winning other contracts we might have otherwise pursued.

In circumstances where contracts are held by other companies and are scheduled to expire, we still may not be provided the opportunity to bid on those contracts if the U.S. government determines to extend the existing contract. If we are unable to win particular contracts that are awarded through the competitive bidding process, we may not be able to operate in the market for services that are provided under those contracts for the duration of those contracts to the extent that there is no additional demand for such services. An inability to consistently win new contract awards over any extended period would have a material adverse effect on our business and results of operations.

The current competitive environment has resulted in an increase in the number of bid protests from unsuccessful bidders on new program awards. It can take many months for the relevant U.S. government agency to resolve protests by one or more of our competitors of contract awards we receive. Bid protests may result in significant expense to us, contract modification or loss of an awarded contract as a result of the award being overturned. Even where we do not lose the awarded contract, the resulting delay in the startup and funding of the work under these contracts may cause our actual results to differ materially and adversely from those anticipated.

A significant majority of our revenue is derived from task orders under indefinite delivery/indefinite quantity, or IDIQ, contract vehicles where we perform in either a prime or subcontract position.

We believe that one of the key elements of our success is our position as the holder of 3,610 active task orders under IDIQ contract vehicles as of March 31, 2019. Our ability to maintain our existing business and win new business depends on our ability to maintain our prime and subcontractor positions on these contracts. The loss, without replacement, of certain of these contract vehicles could have a material adverse effect on our ability to win new business and our operating results. In addition, if the U.S. government elects to use a contract vehicle that we do not hold, we will not be able to compete for work under that contract vehicle as a prime contractor.

We may earn less revenue than projected, or no revenue, under certain of our contracts.

Many of our contracts with our clients are IDIQ contracts. IDIQ contracts provide for the issuance by the client of orders for services or products under the contract, and often contain multi-year terms and unfunded ceiling amounts, which allow but do not commit the U.S. government to purchase products and services from contractors. Our ability to generate revenue under each of these types of contracts depends upon our ability to be awarded task orders for specific services by the client. IDIQ contracts may be awarded to one contractor (single award) or several contractors (multiple award). Multiple contractors must compete under multiple award IDIQ contracts for task orders to provide particular services, and contractors earn revenue only to the extent that they successfully compete for these task orders. A failure to be awarded task orders under such contracts would have a material adverse effect on our results of operations and financial condition.

17

Our earnings and profitability may vary based on the mix of our contracts and may be adversely affected by our failure to accurately estimate or otherwise recover the expenses, time, and resources for our contracts.

We enter into three general types of U.S. government contracts for our services: cost-reimbursable, time-and-materials, and fixed-price. For fiscal 2019, we derived 53% of our revenue from cost-reimbursable contracts, 24% from time-and-materials contracts and 23% from fixed-price contracts.

Each of these types of contracts, to varying degrees, involves the risk that we could underestimate our cost of fulfilling the contract, which may reduce the profit we earn or lead to a financial loss on the contract and adversely affect our operating results.

Under cost-reimbursable contracts, we are reimbursed for allowable costs up to a ceiling and paid a fee, which may be fixed or performance-based. If our actual costs exceed the contract ceiling or are not allowable under the terms of the contract or applicable regulations, we may not be able to recover those costs. In particular, there is increasing focus by the U.S. government on the extent to which government contractors, including us, are able to receive reimbursement for employee compensation, including the adoption of interim rules by federal agencies implementing a section of the Bipartisan Budget Act of 2013 that substantially decreased the level of allowable compensation cost for executive-level employees and further applied the newly reduced limitation to all employees. In addition, there is an increased risk of compensation being deemed unallowable or payments being withheld as a result of U.S. government audit, review or investigation.

Under time-and-materials contracts, we are reimbursed for labor at negotiated hourly billing rates and for certain allowable expenses. We assume financial risk on time-and-materials contracts because our costs of performance may exceed these negotiated hourly rates.

Under fixed-price contracts, we perform specific tasks for a predetermined price. Compared to time-and-materials and cost-reimbursable contracts, fixed-price contracts generally offer higher margin opportunities because we receive the benefits of any cost savings, but involve greater financial risk because we bear the impact of any cost overruns. The U.S. government has generally indicated that it intends to increase its use of fixed price contract procurements. Because we assume the risk for cost overruns and contingent losses on fixed-price contracts, an increase in the percentage of fixed-price contracts in our contract mix would increase our risk of suffering losses.

Additionally, our profits could be adversely affected if our costs under any of these contracts exceed the assumptions we used in bidding for the contract. For example, we may miscalculate the costs, resources, or time needed to complete projects or meet contractual milestones as a result of delays on a particular project, including delays in designs, engineering information, or materials provided by the customer or a third party, delays or difficulties in equipment and material delivery, schedule changes, and other factors, some of which are beyond our control. We have recorded provisions in our consolidated financial statements for losses on our contracts, as required under accounting principles generally accepted in the United States, or GAAP, but our contract loss provisions may not be adequate to cover all actual losses that we may incur in the future.

Our professional reputation and relationships with U.S. government agencies are critical to our business, and any harm to our reputation or relationships could decrease the amount of business the U.S. government does with us, which could have a material adverse effect on our future revenue and growth prospects.

We depend on our contracts with U.S. government agencies for substantially all of our revenue and if our reputation or relationships with these agencies were harmed, our future revenue and growth prospects would be materially and adversely affected. Our reputation and relationship with the U.S. government is a key factor in maintaining and growing revenue under contracts with the U.S. government. In addition, a significant portion of our business relates to designing, developing, and implementing advanced defense and technology systems and products, including cybersecurity products and services. Negative press reports regarding poor contract performance, employee misconduct, information security breaches, engagements in or perceived connections to politically or socially sensitive activities, or other aspects of our business, or regarding government contractors generally, could harm our reputation. In addition, to the extent our performance under a contract does not meet a U.S. government agency’s expectations, the client might seek to terminate the contract prior to its scheduled expiration date, provide a negative assessment of our performance to government-maintained contractor past-performance data repositories, fail to award us additional business under existing contracts or otherwise, and direct future business to our competitors. If our reputation or relationships with these agencies are negatively affected, or if we are suspended or debarred from contracting with government agencies for any reason, such actions would decrease the amount of business that the U.S. government does with us, which would have a material adverse effect on our future revenue and growth prospects.

18

We use estimates in recognizing revenue and if we make changes to estimates used in recognizing revenue, our profitability may be adversely affected.

Revenue from our fixed-price contracts is primarily recognized using the percentage-of-completion method with progress toward completion of a particular contract based on actual costs incurred relative to total estimated costs to be incurred over the life of the contract. Revenue from our cost-reimbursable-plus-award-fee contracts are based on our estimation of award fees over the life of the contract. Estimating costs at completion and award fees on our long-term contracts is complex and involves significant judgment. Adjustments to original estimates are often required as work progresses, experience is gained, and additional information becomes known, even though the scope of the work required under the contract may not change. Any adjustment as a result of a change in estimate is recognized as events become known.

In the event updated estimates indicate that we will experience a loss on the contract, we recognize the estimated loss at the time it is determined. Additional information may subsequently indicate that the loss is more or less than initially recognized, which requires further adjustments in our consolidated financial statements. Changes in the underlying assumptions, circumstances, or estimates could result in adjustments that could have a material adverse effect on our future results of operations.

We may not realize the full value of our backlog, which may result in lower than expected revenue.

As of March 31, 2019, our total backlog was $19.3 billion, of which $3.4 billion was funded. We define backlog to include the following three components:

• Funded Backlog. Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized, less revenue previously recognized on these contracts.

• Unfunded Backlog. Unfunded backlog represents the revenue value of orders (including optional orders) for services under existing contracts for which funding has not been appropriated or otherwise authorized.

• Priced Options. Priced contract options represent 100% of the revenue value of all future contract option periods under existing contracts that may be exercised at our clients’ option and for which funding has not been appropriated or otherwise authorized.

Our backlog does not include contracts that have been awarded but are currently under protest and also does not include any task orders under IDIQ contracts, except to the extent that task orders have been awarded to us under those contracts. For additional disclosure regarding our backlog, please see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Factors and Trends Affecting Our Results of Operations - Sources of Revenue - Contract Backlog."

We historically have not realized all of the revenue included in our total backlog, and we may not realize all of the revenue included in our total backlog in the future. There is a somewhat higher degree of risk in this regard with respect to unfunded backlog and priced options. In addition, there can be no assurance that our backlog will result in actual revenue in any particular period. This is because the actual receipt, timing, and amount of revenue under contracts included in backlog are subject to various contingencies, including congressional appropriations, many of which are beyond our control. In particular, delays in the completion of the U.S. government’s budgeting process and the use of continuing resolutions could adversely affect our ability to timely recognize revenue under our contracts included in backlog. Furthermore, the actual receipt of revenue from contracts included in backlog may never occur or may be delayed because: a program schedule could change or the program could be canceled; a contract’s funding or scope could be reduced, modified, delayed, de-obligated or terminated early, including as a result of a lack of appropriated funds or as a result of cost cutting initiatives and other efforts to reduce U.S. government spending and/or the automatic federal defense spending cuts required by sequestration; in the case of funded backlog, the period of performance for the contract has expired or the U.S. government has exercised its unilateral right to cancel multi-year contracts and related orders or terminate existing contracts for convenience or default; in the case of unfunded backlog, funding may not be available; or, in the case of priced options, our clients may not exercise their options. In addition, consulting staff headcount growth is the primary means by which we are able to recognize revenue growth. Any inability to hire additional appropriately qualified personnel or failure to timely and effectively deploy such additional personnel against funded backlog could negatively affect our ability to grow our revenue. We may also not recognize revenue on funded backlog due to, among other reasons, the tardy submissions of invoices by our subcontractors and the expiration of the relevant appropriated funding in accordance with a predetermined expiration date such as the end of the U.S. government's fiscal year. The amount of our funded backlog is also subject to change, due to, among other factors: changes in congressional appropriations that reflect changes in U.S. government policies or priorities resulting from various military, political, economic or international developments; changes in the use of U.S. government contracting vehicles, and the provisions therein used to procure our services; and adjustments to the scope of services under, or cancellation of contracts, by the U.S. government at any time. Furthermore, even if our backlog results in revenue, the contracts may not be profitable.

19

We may fail to attract, train and retain skilled and qualified employees, which may impair our ability to generate revenue, effectively serve our clients, and execute our growth strategy.

Our business depends in large part upon our ability to attract and retain sufficient numbers of highly qualified individuals who may have advanced degrees in areas such as information technology as well as appropriate security clearances. We compete for such qualified personnel with other U.S. government contractors, the U.S. government, and private industry, and such competition is intense. Personnel with the requisite skills, qualifications, or security clearance may be in short supply or generally unavailable. Our ability to attract and retain skilled and qualified employees may also be impacted by our engagements in, or perceived connections to, politically or socially sensitive activities. In addition, our ability to recruit, hire, and internally deploy former employees of the U.S. government is subject to complex laws and regulations, which may serve as an impediment to our ability to attract such former employees, and failure to comply with these laws and regulations may expose us and our employees to civil or criminal penalties. If we are unable to recruit and retain a sufficient number of qualified employees, or fail to deploy such employees or obtain their appropriate security clearances in a timely manner, our ability to maintain and grow our business and to effectively serve our clients could be limited and our future revenue and results of operations could be materially and adversely affected. Furthermore, to the extent that we are unable to make necessary permanent hires to appropriately serve our clients, we could be required to engage larger numbers of contracted personnel, which could reduce our profit margins.

If we are able to attract sufficient numbers of qualified new hires, training and retention costs may place significant demands on our resources. In addition, to the extent that we experience attrition in our employee ranks, we may realize only a limited or no return on such invested resources, and we would have to expend additional resources to hire and train replacement employees. The loss of services of key personnel could also impair our ability to perform required services under some of our contracts and to retain such contracts, as well as our ability to win new business.

We may fail to obtain and maintain necessary security clearances which may adversely affect our ability to perform on certain contracts.

Many U.S. government programs require contractor employees and facilities to have security clearances. Depending on the level of required clearance, security clearances can be difficult and time-consuming to obtain. If we or our employees are unable to obtain or retain necessary security clearances, we may not be able to win new business, and our existing clients could terminate their contracts with us or decide not to renew them. To the extent we are not able to obtain and maintain facility security clearances or engage employees with the required security clearances for a particular contract, we may not be able to bid on or win new contracts, or effectively rebid on expiring contracts, as well as lose existing contracts, which may adversely affect our operating results and inhibit the execution of our growth strategy.

Our profitability could suffer if we are not able to timely and effectively utilize our employees or manage our cost structure.

The cost of providing our services, including the degree to which our employees are utilized, affects our profitability. The degree to which we are able to utilize our employees in a timely manner or at all is affected by a number of factors, including:

• our ability to transition employees from completed projects to new assignments and to hire, assimilate, and deploy new employees;

• our ability to forecast demand for our services and to maintain and deploy headcount that is aligned with demand, including employees with the right mix of skills and experience to support our projects;

• our employees’ inability to obtain or retain necessary security clearances;

• our ability to manage attrition; and

• our need to devote time and resources to training, business development, and other non-chargeable activities.

If our employees are under-utilized, our profit margin and profitability could suffer. Additionally, if our employees are over-utilized, it could have a material adverse effect on employee engagement and attrition, which would in turn have a material adverse impact on our business.

Our profitability is also affected by the extent to which we are able to effectively manage our overall cost structure for operating expenses, such as wages and benefits, overhead and capital and other investment-related expenditures. If we are unable to effectively manage our costs and expense and achieve efficiencies, our competitiveness and profitability may be adversely affected.

20

We may lose one or more members of our senior management team or fail to develop new leaders, which could cause the disruption of the management of our business.

We believe that the future success of our business and our ability to operate profitably depends on the continued contributions of the members of our senior management and the continued development of new members of senior management. We rely on our senior management to generate business and execute programs successfully. In addition, the relationships and reputation that many members of our senior management team have established and maintain with our clients are important to our business and our ability to identify new business opportunities. The loss of any member of our senior management or our failure to continue to develop new members could impair our ability to identify and secure new contracts, to maintain good client relations, and to otherwise manage our business.

Our employees or subcontractors may engage in misconduct or other improper activities, which could harm our ability to conduct business with the U.S. government.

We are exposed to the risk that employee or subcontractor fraud or other misconduct could occur. Misconduct by employees or subcontractors could include intentional or unintentional failures to comply with U.S. government procurement regulations, engaging in other unauthorized activities, or falsifying time records. Employee or subcontractor misconduct could also involve the improper use of our clients’ sensitive or classified information, or the inadvertent or intentional disclosure of our or our clients' sensitive information in violation of our contractual, statutory, or regulatory obligations. It is not always possible to deter employee or subcontractor misconduct, and the precautions we take to prevent and detect this activity may not be effective in controlling unknown or unmanaged risks or losses, which could materially harm our business. As a result of such misconduct, our employees could lose their security clearance and we could face fines and civil or criminal penalties, loss of facility clearance accreditation, and suspension, proposed debarment or debarment from bidding for or performing under contracts with the U.S. government, as well as reputational harm, which would materially and adversely affect our results of operations and financial condition.

We face intense competition from many competitors, which could cause us to lose business, lower prices and suffer employee departures.

Our business operates in a highly competitive industry, and we generally compete with a wide variety of U.S. government contractors, including large defense contractors, diversified service providers, and small businesses. We also face competition from entrants into our markets including companies divested by large prime contractors in response to increasing scrutiny of organizational conflicts of interest issues. There is also a significant industry trend towards consolidation, which may result in the emergence of companies that are better able to compete against us. Some of these companies possess greater financial resources and larger technical staffs, and others have smaller and more specialized staffs. These competitors could, among other things:

• divert sales from us by winning very large-scale government contracts, a risk that is enhanced by the recent trend in government procurement practices to bundle services into larger contracts;

• force us to charge lower prices in order to win or maintain contracts;

• seek to hire our employees; or

• adversely affect our relationships with current clients, including our ability to continue to win competitively awarded engagements where we are the incumbent.

If we lose business to our competitors or are forced to lower our prices or suffer employee departures, our revenue and our operating profits could decline. In addition, we may face competition from our subcontractors who, from time to time, seek to obtain prime contractor status on contracts for which they currently serve as a subcontractor to us. If one or more of our current subcontractors are awarded prime contractor status on such contracts in the future, it could divert sales from us and could force us to charge lower prices, which could have a material adverse effect on our revenue and profitability.

Our failure to maintain strong relationships with other contractors, or the failure of contractors with which we have entered into a sub- or prime contractor relationship to meet their obligations to us or our clients, could have a material adverse effect on our business and results of operations.

Maintaining strong relationships with other U.S. government contractors, who may also be our competitors, is important to our business and our failure to do so could have a material adverse effect on our business, prospects, financial condition, and operating results. To the extent that we fail to maintain good relations with our subcontractors or other prime contractors due to either perceived or actual performance failures or other conduct, they may refuse to hire us as a subcontractor in the future or to work with us as our subcontractor. In addition, other contractors may choose not to use us as a subcontractor or choose not to perform work for us as a subcontractor for any number of additional reasons, including because they choose to establish relationships with our competitors or because they choose to directly offer services that compete with our business.

21

As a prime contractor, we often rely on other companies to perform some of the work under a contract, and we expect to continue to depend on relationships with other contractors for portions of our delivery of services and revenue in the foreseeable future. If our subcontractors fail to perform their contractual obligations, our operating results and future growth prospects could be impaired. There is a risk that we may have disputes with our subcontractors arising from, among other things, the quality and timeliness of work performed by the subcontractor, client concerns about the subcontractor, our failure to extend existing task orders or issue new task orders under a subcontract, or our hiring of a subcontractor’s personnel. In addition, if any of our subcontractors fail to deliver the agreed-upon supplies or perform the agreed-upon services on a timely basis, our ability to fulfill our obligations as a prime contractor may be jeopardized. Material losses could arise in future periods and subcontractor performance deficiencies could result in a client terminating a contract for default. A termination for default could expose us to liability and have an adverse effect on our ability to compete for future contracts and orders.

We estimate that revenue derived from contracts under which we acted as a subcontractor to other companies represented 8% of our revenue for fiscal 2019. As a subcontractor, we often lack control over fulfillment of a contract, and poor performance on the contract could tarnish our reputation, even when we perform as required, and could cause other contractors to choose not to hire us as a subcontractor in the future. If the U.S. government terminates or reduces other prime contractors’ programs or does not award them new contracts, subcontracting opportunities available to us could decrease, which would have a material adverse effect on our financial condition and results of operations. In addition, as a subcontractor, we may be unable to collect payments owed to us by the prime contractor, even if we have performed our obligations under the contract, as a result of, among other things, the prime contractor’s inability to fulfill the contact. Due to certain common provisions in subcontracts in certain countries, we could also experience delays in receiving payment if the prime contractor experiences payment delays, which could have an adverse effect on our financial condition and results of operations.

Adverse judgments or settlements in legal disputes could result in materially adverse monetary damages or injunctive relief and damage our reputation.

We are subject to, and may become a party to, a variety of litigation or other claims and suits that arise from time to time in the ordinary course of our business. For example, our performance under U.S. government contracts and compliance with the terms of those contracts and applicable laws and regulations are subject to continuous audit, review, and investigation by the U.S. government which may include such investigative techniques as subpoenas or civil investigative demands. As more fully described under "Item 3. Legal Proceedings", the U.S. Department of Justice (the "DOJ") is conducting a civil and criminal investigation of the Company, and the Company has also been in contact with other regulatory agencies and bodies, including the Securities and Exchange Commission, which notified the Company that it is conducting an investigation that the Company believes relates to matters that are also the subject of the DOJ's investigation. The Company may receive additional regulatory or governmental inquiries related to the matters that are the subject of the DOJ's investigation. In accordance with the Company's practice, the Company is cooperating with all relevant government parties. The total cost associated with these matters will depend on many factors, including the duration of these matters and any related finding. Given the nature of our business, these audits, reviews, and investigations may focus, among other areas, on various aspects of procurement integrity, labor time reporting, sensitive and/or classified information access and control, executive compensation, and post government employment restrictions. In addition, from time to time, we are also involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with clients and contractors, intellectual property disputes, and other business matters. Any such claims or investigations may be time-consuming, costly, divert management resources, or otherwise have a material adverse effect on our result of operations.

Additionally, over time, we have had disputes with current and former employees involving alleged violations of civil rights, wage and hour, and worker’s compensation laws. Further, as more fully described under “Item 3. Legal Proceedings,” six former officers and stockholders who had departed the company prior to the Carlyle Acquisition have filed a total of nine suits in various jurisdictions against us and certain of our current and former directors and officers. Each of the suits arises out of the acquisition and alleges that the former stockholders are entitled to certain payments that they would have received if they had held their stock at the time of the Carlyle Acquisition. Three of these suits have been dismissed with all appeals exhausted. Two suits were settled on April 16, 2015. One of the remaining suits had its Petition for Writ of Certiorari to the United States Supreme Court denied and the other three were consolidated and ultimately dismissed. The United States Court of Appeals for the Second Circuit affirmed dismissal of the suit on July 13, 2017, except for one plaintiff's securities fraud claim, which was remanded to give the plaintiff leave to file another amended complaint. On April 6, 2018, the plaintiff filed an amended complaint, alleging that the Company and certain former officers and directors violated Sections 10(b), 20(a) and 14(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). On April 25, 2018, the court entered an order postponing the deadline within which the defendants must answer or move to dismiss the amended complaint.

22

The results of litigation and other legal proceedings, including the other claims described under "Item 3. Legal Proceedings," are inherently uncertain and adverse judgments or settlements in some or all of these legal disputes may result in materially adverse monetary damages or injunctive relief against us. Any claims or litigation, even if fully indemnified or insured, could damage our reputation and make it more difficult to compete effectively or obtain adequate insurance in the future. The litigation and other legal proceedings described under “Item 3. Legal Proceedings” are subject to future developments and management’s view of these matters may change in the future.

We face certain significant risk exposures and potential liabilities that may not be adequately covered by indemnity or insurance.

A significant portion of our business relates to designing, developing, and implementing advanced defense and technology systems and products, including cybersecurity products and services. New technologies may be untested or unproven. We maintain insurance policies that mitigate against risk and potential liabilities related to our operations, including data breaches. This insurance is maintained in amounts that we believe are reasonable. However, our insurance coverage may not be adequate to cover those claims or liabilities, and we may be forced to bear significant costs from an accident or incident. The amount of the insurance coverage we maintain or indemnification to which we may be contractually or otherwise entitled may not be adequate to cover all claims or liabilities. Accordingly, we may be forced to bear substantial costs resulting from risks and uncertainties of our business which would negatively impact our results of operations, financial condition or liquidity.

Systems that we develop, integrate, maintain, or otherwise support could experience security breaches which may damage our reputation with our clients and hinder future contract win rates.

We develop, integrate, maintain, or otherwise support systems and provide services that include managing and protecting information involved in intelligence, national security, and other sensitive or classified government functions. Our systems also store and process sensitive information for commercial clients, including personally identifiable, health and financial information. The cyber and security threats that our clients face have grown more frequent and sophisticated. A security breach in one of these systems could cause serious harm to our business, damage our reputation, and prevent us from being eligible for further work on sensitive systems for U.S. government or commercial clients. Work for non-U.S. government and commercial clients involving the protection of information systems or that store clients' information could also be harmed due to associated security breaches. Damage to our reputation or limitations on our eligibility for additional work or any liability resulting from a security breach in one of the systems we develop, install, maintain, or otherwise support could have a material adverse effect on our results of operations.

Certain services we provide and technologies we develop are designed to detect and monitor threats to our clients and may expose our staff to financial loss or physical or reputational harm.

We help our clients detect, monitor and mitigate threats to their people, information and facilities. These threats may originate from nation states, terrorist or criminal actors, activist hackers or others who seek to harm our clients. Successful attacks on our clients may cause reputational harm to us and our clients, as well as liability to our clients or third parties. In addition, if we are associated with our clients in this regard, our staff, information and facilities may be targeted by a similar group of threat actors and may be at risk for financial loss, or physical or reputational harm.

Internal system or service failures, or those of our vendors, including as a result of cyber or other security threats, could disrupt our business and impair our ability to effectively provide our services to our clients, which could damage our reputation and have a material adverse effect on our business and results of operations.

We create, implement, and maintain information technology and engineering systems and also use vendors to provide services that are often critical to our clients' operations, some of which involve sensitive information and may be conducted in war zones or other hazardous environments, or include information whose confidentiality is protected by law. As a result, we are subject to systems or service failures, not only resulting from our own failures or the failures of third-party service providers, natural disasters, power shortages, or terrorist attacks, but also from continuous exposure to constantly evolving cyber and other security threats, including computer viruses and malware, attacks by computer hackers or physical break-ins. There has been an increase in the frequency and sophistication of the cyber and security threats we face, with attacks ranging from those common to businesses generally to those that are more advanced and persistent, which may target us because, as a cybersecurity services contractor, we hold classified, controlled unclassified and other sensitive information. As a result, we and our vendors face a heightened risk of a security breach or disruption resulting from an attack by computer hackers, foreign governments, and cyber terrorists. While we put in place policies, controls, and technologies to help detect and protect against such attacks, we cannot guarantee that future incidents will not occur, and if an incident does occur, we may not be able to successfully mitigate the impact. We have been the target of these types of attacks in the past and future attacks are likely to occur. If successful, these types of attacks on our network or other systems or service failures could have a material adverse effect on our business and results of operations, due to, among other things, the loss of client or proprietary data, interruptions or delays in our clients' businesses, and damage to our reputation. In addition, the failure or disruption of our systems, communications, vendors, or utilities could cause us to interrupt or suspend our operations, which could have a material

23

adverse effect on our business and results of operations. In addition, if our employees inadvertently do not adhere to appropriate information security protocols, our protocols are inadequate, or our employees intentionally avoid these protocols, our or our clients' sensitive information may be released thereby causing significant negative impacts to our reputation and exposing us or our clients to liability.

If our or our vendors' systems, services, or other applications have significant defects or errors, are successfully attacked by cyber and other security threats, suffer delivery delays, or otherwise fail to meet our clients’ expectations, we may:

• lose revenue due to adverse client reaction;

• be required to provide additional services to a client at no charge;

• incur additional costs related to remediation, monitoring and increasing our cybersecurity;

• lose revenue due to the deployment of internal staff for remediation efforts instead of client assignments;

• receive negative publicity, which could damage our reputation and adversely affect our ability to attract or retain clients;

• be unable to successfully market services that are reliant on the creation and maintaining of secure information technology systems to U.S. government, international, and commercial clients;

• suffer claims by clients or impacted third parties for substantial damages, particularly as a result of any successful network or systems breach and exfiltration of client and/or third party information; or

• incur significant costs, including fines from government regulators related to complying with applicable federal or state law, including laws pertaining to the security and protection of personal information.

In addition to any costs resulting from contract performance or required corrective action, these failures may result in increased costs or loss of revenue if they result in clients postponing subsequently scheduled work or canceling or failing to renew contracts.

The costs related to cyber or other security threats or disruptions may not be fully insured or indemnified by other means. Additionally, some cyber technologies and techniques that we utilize or develop may raise potential liabilities related to legal compliance intellectual property and civil liberties, including privacy concerns, which may not be fully insured or indemnified. We may not be able to obtain and maintain insurance coverage on reasonable terms or in sufficient amounts to cover one or more large claims, or the insurer may disclaim coverage as to some types of future claims. The successful assertion of any large claim against us could seriously harm our business. Even if not successful, these claims could result in significant legal and other costs, may be a distraction to our management, and may harm our client relationships. In certain new business areas, we may not be able to obtain sufficient insurance and may decide not to accept or solicit business in these areas.

As a contractor supporting defense and national security clients, we are also subject to regulatory compliance requirements under the Defense Federal Acquisition Regulation Supplement and other federal regulations requiring that our networks and IT systems comply with the security and privacy controls in National Institute of Standards and Technology Special Publications. To the extent that we do not comply with the applicable security and control requirements, unauthorized access or disclosure of sensitive information could potentially result in a contract termination that has a material adverse effect on our business and financial results and reputational harm.

Implementation of various data privacy and cybersecurity laws could require significant investment into ongoing compliance activities, trigger potential liability under such laws, and limit our ability to use personal data.

Any failure by us, our vendors or other business partners to comply with international, federal, or state laws regarding data privacy or cybersecurity could result in regulatory actions or lawsuits against us, legal liability, fines, damages and other costs. We may also incur substantial expenses in implementing and maintaining compliance with such laws. For example, the General Data Protection Regulation (“GDPR”), implemented on May 25, 2018 across the European Union (“EU”), imposes more stringent data protection obligations on companies that process data in the EU. GDPR has created new compliance obligations, requires investment into ongoing data protection activities and documentation requirements, and creates the potential for significantly increased fines for noncompliance. In addition, California has enacted the California Consumer Protection Privacy Act of 2018 (“CCPA”), which provides new consumer privacy rights to natural persons residing in California. The CCPA is the most prescriptive general privacy law in the United States, and may lead to similar laws being enacted in other U.S. states or at the federal level. It is possible that the CCPA or similar laws will be deemed applicable to some aspects of our business, which would impose new compliance obligations and require additional investment into data protection activities. The CCPA’s effective date deadline is January 1, 2020, and it is anticipated that the California Attorney General will issue implementing regulations at a date that is not yet known. Any obligations that may be imposed on us under CCPA or similar laws may be different from or in addition to those required by GDPR, which may cause additional expense for compliance across various jurisdictions. GDPR, California law, and the laws of other U.S. states also impose obligations to

24

maintain a cybersecurity program at a certain level of quality, as well as obligations to give notice to affected individuals and to certain regulators in the event of a data breach.

Failure to adequately protect, maintain, or enforce our rights in our intellectual property may adversely limit our competitive position.

We rely upon a combination of nondisclosure agreements and other contractual arrangements, as well as copyright, trademark, patent, and trade secret laws to protect our proprietary information. We also enter into proprietary information and intellectual property agreements with employees, which require them to disclose any inventions created during employment, to convey such rights to inventions to us, and to restrict any disclosure of proprietary information. Trade secrets are generally difficult to protect. Although our employees are subject to confidentiality obligations, this protection may be inadequate to deter or prevent misappropriation of our confidential information and/or the infringement of our patents and copyrights. Further, we may be unable to detect unauthorized use of our intellectual property or otherwise take appropriate steps to enforce our rights. Failure to adequately protect, maintain, or enforce our intellectual property rights may adversely limit our competitive position.

Assertions by third parties of infringement, misappropriation or other violations by us of their intellectual property rights could result in significant costs and substantially harm our business and operating results.

In recent years, there has been significant litigation involving intellectual property rights in technology industries. We may face from time to time, allegations that we or a supplier or customer have violated the rights of third parties, including patent, trademark, and other intellectual property rights. If, with respect to any claim against us for violation of third-party intellectual property rights, we are unable to prevail in the litigation or retain or obtain sufficient rights or develop non-infringing intellectual property or otherwise alter our business practices on a timely or cost-efficient basis, our business and competitive position may be adversely affected.

Any infringement, misappropriation or related claims, whether or not meritorious, are time consuming, divert technical and management personnel, and are costly to resolve. As a result of any such dispute, we may have to develop non-infringing technology, pay damages, enter into royalty or licensing agreements, cease utilizing certain products or services, or take other actions to resolve the claims. These actions, if required, may be costly or unavailable on terms acceptable to us.

Our focus on new growth areas for our business entails risks, including those associated with new relationships, clients, talent needs, capabilities, service offerings, and maintaining our collaborative culture and core values.

We are focused on growing our presence in our addressable markets by: expanding our relationships with existing clients, developing new clients by leveraging our core competencies, further developing our existing capabilities and service offerings, creating new capabilities and service offerings to address our clients' emerging needs, and undertaking business development efforts focused on identifying near-term developments and long-term trends that may pose significant challenges for our clients. These efforts entail inherent risks associated with innovation and competition from other participants in those areas, potential failure to help our clients respond to the challenges they face, our ability to comply with uncertain evolving legal standards applicable to certain of our service offerings, including those in the cybersecurity area, and, with respect to potential international growth, risks associated with operating in foreign jurisdictions, such as compliance with applicable foreign and U.S. laws and regulations that may impose different and, occasionally, conflicting or contradictory requirements, and the economic, legal, and political conditions in the foreign jurisdictions in which we operate, including the GDPR. See "—Implementation of various data privacy and cybersecurity laws could require significant investment into ongoing compliance activities, trigger potential liability under such laws, and limit our ability to use personal data." As we attempt to develop new relationships, clients, capabilities, and service offerings, these efforts could harm our results of operations due to, among other things, a diversion of our focus and resources and actual costs, opportunity costs of pursuing these opportunities in lieu of others and a failure to reach a profitable return on our investments in new technologies, capabilities, and businesses, including expenses on research and development investments, and these efforts could ultimately be unsuccessful. Additionally, the possibility exists that our competitors might develop new capabilities or service offerings that might cause our existing capabilities and service offerings to become obsolete. If we fail in our new capabilities development efforts or our capabilities or services fail to achieve market acceptance more rapidly than our competitors, our ability to procure new contracts could be negatively impacted, which would negatively impact our results of operations and financial condition.

In addition, our ability to grow our business by leveraging our operating model to efficiently and effectively deploy our people across our client base is largely dependent on our ability to maintain our collaborative culture. To the extent that we are unable to maintain our culture for any reason, including our effort to focus on new growth areas or acquire new businesses with different corporate cultures, we may be unable to grow our business. Any such failure could have a material adverse effect on our business and results of operations.

In addition, with the growth of our U.S. and international operations, we are now providing client services and undertaking business development efforts in numerous and disparate geographic locations both domestically and

25

internationally. Our ability to effectively serve our clients is dependent upon our ability to successfully leverage our operating model across all of these and any future locations, maintain effective management controls over all of our locations to ensure, among other things, compliance with applicable laws, rules and regulations, and instill our core values in all of our personnel at each of these and any future locations. Any inability to ensure any of the foregoing could have a material adverse effect on our business and results of operations.

We are subject to risks associated with operating internationally.

Our business operations are subject to a variety of risks associated with conducting business internationally, including:

• Changes in or interpretations of laws or policies that may adversely affect the performance of our services;

• Political instability in foreign countries;

• Imposition of inconsistent or contradictory laws or regulations;

• Reliance on the U.S. or other governments to authorize us to export products, technology, and services to clients and other business partners;

• Conducting business in places where laws, business practices, and customs are unfamiliar or unknown; and

• Imposition of limitations on or increase of withholding and other taxes on payments by foreign subsidiaries or joint ventures;

• Volatility in foreign currencies if the United Kingdom exits from the European Union, particularly in countries where the Company has substantial activities; and

• Imposition of tariffs or embargoes, export controls and other trade restrictions, including the recent tariffs imposed by the U.S. and China and the possibility of additional tariffs or other trade restrictions relating to trade.

In addition, we are subject to the U.S. Foreign Corrupt Practices Act, or the FCPA, and other laws that prohibit improper payments or offers of payments to foreign governments and their officials and political parties by business entities for the purpose of obtaining or retaining business. We have operations and deal with governmental clients in countries known to experience corruption, including certain emerging countries in the Middle East and Southeast Asia. Our activities in these countries create the risk of unauthorized payments or offers of payments by one of our employees, consultants or contractors that could be in violation of various laws including the FCPA and other anti-corruption laws, even though these parties are not always subject to our control. Our international operations also involve activities involving the transmittal of information, which may include personal data, that may expose us to data privacy laws in the jurisdictions in which we operate. If our data protection practices become subject to new or different restrictions, and to the extent such practices are not compliant with the laws of the countries in which we process data, we could face increased compliance expenses and face penalties for violating such laws or be excluded from those markets altogether, in which case our operations could be adversely affected. We are also subject to import-export control regulations restricting the use and dissemination of information classified for national security purposes and the export of certain products, services, and technical data, including requirements regarding any applicable licensing of our employees involved in such work.

If we were to fail to comply with the FCPA, other anti-corruption laws, applicable import-export control regulations, data privacy laws, or other applicable rules and regulations, we could be subject to substantial civil and criminal penalties, including fines for our company and incarceration for responsible employees and managers, suspension or debarment, and the possible loss of export or import privileges which could have a material adverse effect on our business and results of operations.

Changes to our operating structure, capabilities or strategy intended to address our clients’ needs, respond to developments in our markets and grow our business may not be successful.

We routinely review our operating structure, capabilities and strategy to determine whether we are effectively meeting the needs of existing clients, effectively responding to developments in our markets and successfully building platforms intended to provide the foundation for the future growth of our business. The outcome of any such review is difficult to predict and the extent of changes to our business following such a review, if any, are dependent in part upon the nature and extent of the review.

The implementation of changes to our operating structure, capabilities, strategy or any other aspect of our business following an internal review, may materially alter various aspects of our business or our business model as an entirety and there can be no assurance that any such changes will be successful or that they will not ultimately have a negative effect on our business and results of operations.

26

Many of our contracts with the U.S. government are classified or subject to other security restrictions, which may limit investor insight into portions of our business.

We derive a substantial portion of our revenue from contracts with the U.S. government that are classified or subject to security restrictions that preclude the dissemination of certain information. In addition, a significant number of our employees have security clearances which preclude them from providing information regarding certain of our clients and services provided to such clients to other of our employees without security clearances and investors. Because we are limited in our ability to provide information about these contracts and services, the various risks associated with these contracts or services or any dispute or claims relating to such contracts or services, you may not have important information concerning our business, which will limit your insight into a substantial portion of our business and therefore may be less able to fully evaluate the risks related to that portion of our business.

If we cannot collect our receivables or if payment is delayed, our business may be adversely affected by our inability to generate cash flow, provide working capital, or continue our business operations.

We depend on the timely collection of our receivables to generate cash flow, provide working capital, and continue our business operations. If the U.S. government or any prime contractor for whom we are a subcontractor fails to pay or delays the payment of invoices for any reason, our business and financial condition may be materially and adversely affected. The U.S. government may delay or fail to pay invoices for a number of reasons, including lack of appropriated funds, lack of an approved budget, lack of revised or final settled billing rates as a result of open audit years or as a result of audit findings by government regulatory agencies. Some prime contractors for whom we are a subcontractor have significantly fewer financial resources than we do, which may increase the risk that we may not be paid in full or that payment may be delayed.

Recent efforts by the U.S. government to revise its organizational conflict of interest rules could limit our ability to successfully compete for new contracts or task orders, which would adversely affect our results of operations.

Recent efforts by the U.S. government to reform its procurement practices have focused, among other areas, on the separation of certain types of work to facilitate objectivity and avoid or mitigate organizational conflicts of interest and the strengthening of regulations governing organizational conflicts of interest. Organizational conflicts of interest may arise from circumstances in which a contractor has:

• impaired objectivity during performance;

• unfair access to non-public information; or

• the ability to set the “ground rules” for another procurement for which the contractor competes.

A focus on organizational conflicts of interest issues has resulted in legislation and a proposed regulation aimed at increasing organizational conflicts of interest requirements, including, among other things, separating sellers of products and providers of advisory services in major defense acquisition programs. In addition, the U.S. government is working to adopt a FAR rule to address organizational conflicts of interest issues that will apply to all government contractors, including us, in Department of Defense and other procurements. A future FAR rule may also increase the restrictions in current organizational conflicts of interest regulations and rules. To the extent that proposed and future organizational conflicts of interest laws, regulations, and rules, limit our ability to successfully compete for new contracts or task orders with the U.S. government, either because of organizational conflicts of interest issues arising from our business, or because companies with which we are affiliated, or with which we otherwise conduct business, create organizational conflicts of interest issues for us, our results of operations could be materially and adversely affected.

We may consummate acquisitions, investments, joint ventures and divestitures, which involve numerous risks and uncertainties.

As part of our operating strategy, we selectively pursue acquisitions, investments, partnerships and joint ventures. These transactions pose many risks, including:

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

• we may not be able to compete successfully for identified acquisition and investment candidates, complete acquisitions and investments, or accurately estimate the financial effect of acquisitions and investments on our business;

• future acquisitions and investments may require us to issue common stock or spend significant cash, resulting in dilution of ownership or additional debt leverage;

• we may have difficulty retaining an acquired company’s key employees or clients;

• we may have difficulty integrating acquired businesses and investments, resulting in unforeseen difficulties, such as incompatible accounting, information management, or other control systems, and greater expenses than expected;

27

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

• as a result of an acquisition or investment, we may incur additional debt and we may need to record write-downs from future impairments of intangible assets, each of which could reduce our future reported earnings; we may have difficulty integrating personnel from the acquired company with our people and our core values; and

• we may not be able to effectively influence the operations of our joint ventures or partnerships, or we may be exposed to certain liabilities if our partners do not fulfill their obligations.

In connection with any acquisition or investment that we make, there may be liabilities that we fail to discover or that we inadequately assess, and we may fail to discover any failure of a target company to have fulfilled its contractual obligations to the U.S. government or other clients. Acquired entities and investments may not operate profitably or result in improved operating performance. Additionally, we may not realize anticipated synergies, business growth opportunities, cost savings, and other benefits, which could have a material adverse effect on our business and results of operations.

In addition, we may divest businesses, including businesses that are no longer a part of our ongoing strategic plan. These divestitures similarly require significant investment of time and resources, may disrupt our business, distract management from other responsibilities and may result in losses on disposal or continued financial involvement in the divested business, including through indemnification, guarantee or other financial arrangements, for a period of time, following the transaction, which could adversely affect our financial results. In addition, we may be unable to complete strategic divestitures on satisfactory terms and conditions, including non-competition arrangements, or within expected time frames.

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 March 31, 2019, the value of our goodwill was $1.6 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. Such non-cash impairment charges could have a material adverse effect on our results of operations in the period in which they are recognized.

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

We are subject to taxation in the U.S. and certain other foreign jurisdictions. Any future changes in applicable federal, state and local, or foreign tax laws and regulations or their interpretation or application, including those that could have a retroactive effect, could result in the Company incurring additional tax liabilities in the future. In particular, we will continue to assess the effect of the Tax Cuts and Jobs Act (the "2017 Tax Act") on our business as it relates to taxes on low taxed intangible foreign income as well as deduction for foreign derived intangible income. Additionally, any final determination of tax audits or related litigation may be materially different than our current provisional amounts, which could materially affect our tax obligations and effective tax rate. For additional information regarding the 2017 Tax Act, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations". For a description of our related accounting policies, refer to Note 2 and Note 14 to our accompanying consolidated financial statements.

Risks Related to Our Industry

Our U.S. government contracts may be terminated by the government at any time and may contain other provisions permitting the government to discontinue contract performance, and if lost contracts are not replaced, our operating results may differ materially and adversely from those anticipated.

U.S. government contracts contain provisions and are subject to laws and regulations that provide government clients with rights and remedies not typically found in commercial contracts. These rights and remedies allow government clients, among other things, to:

• terminate existing contracts, with short notice, for convenience as well as for default;

• reduce orders under or otherwise modify contracts;

• for contracts subject to the Truthful Cost or Pricing Data Statute, reduce the contract price or cost where it was increased because a contractor or subcontractor furnished cost or pricing data during negotiations that was not complete, accurate, and current;

28

• for some contracts, (i) demand a refund, make a forward price adjustment, or terminate a contract for default if a contractor provided inaccurate or incomplete data during the contract negotiation process and (ii) reduce the contract price under certain triggering circumstances, including the revision of price lists or other documents upon which the contract award was predicated;

• terminate our facility security clearances and thereby prevent us from receiving classified contracts;

• cancel multi-year contracts and related orders if funds for contract performance for any subsequent year become unavailable;

• decline to exercise an option to renew a multi-year contract or issue task orders in connection with IDIQ contracts;

• claim rights in solutions, systems, and technology produced by us, appropriate such work-product for their continued use without continuing to contract for our services and disclose such work-product to third parties, including other U.S. government agencies and our competitors, which could harm our competitive position;

• prohibit future procurement awards with a particular agency due to a finding of organizational conflicts of interest based upon prior related work performed for the agency that would give a contractor an unfair advantage over competing contractors, or the existence of conflicting roles that might bias a contractor’s judgment;

• subject the award of contracts to protest by competitors, which may require the contracting federal agency or department to suspend our performance pending the outcome of the protest and may also result in a requirement to resubmit offers for the contract or in the termination, reduction, or modification of the awarded contract;

• suspend or debar us from doing business with the U.S. government; and

• control or prohibit the export of our services.

Recent and potential future budget cuts, the impact of sequestration and recent efforts by the Office of Management and Budget to decrease federal awards for management support services, may cause agencies with which we currently have contracts to terminate, reduce the number of task orders under or fail to renew such contracts. If a U.S. government client were to unexpectedly terminate, cancel, or decline to exercise an option to renew with respect to one or more of our significant contracts, or suspend or debar us from doing business with the U.S. government, our revenue and operating results would be materially harmed.

The U.S. government may revise its procurement, contract or other practices in a manner adverse to us.

The U.S. government may:

• revise its procurement practices or adopt new contract laws, rules, and regulations, such as cost accounting standards, organizational conflicts of interest, and other rules governing inherently governmental functions at any time;

• reduce, delay, or cancel procurement programs resulting from U.S. government efforts to improve procurement practices and efficiency;

• limit the creation of new government-wide or agency-specific multiple award contracts;

• face restrictions or pressure from government employees and their unions regarding the amount of services the U.S. government may obtain from private contractors;

• award contracts on a technically acceptable/lowest cost basis in order to reduce expenditures, and we may not be the lowest cost provider of services;

• adopt new socio-economic requirements, including setting aside procurement opportunities to small, disadvantaged businesses;

• change the basis upon which it reimburses our compensation and other expenses or otherwise limit such reimbursements; and

• at its option, terminate or decline to renew our contracts.

In addition, any new contracting methods could be costly or administratively difficult for us to implement and could adversely affect our future revenue and profit margin. In addition, changes to the procurement system could cause delays in the procurement decision-making process. Any such changes to the U.S. government’s procurement practices or the adoption of new contracting rules or practices could impair our ability to obtain new or re-compete contracts and any such changes or increased associated costs could materially and adversely affect our results of operations.

29

The U.S. government may prefer minority-owned, small and small disadvantaged businesses; therefore, we may have fewer opportunities to bid for.

As a result of the Small Business Administration set-aside program, the U.S. government may decide to restrict certain procurements only to bidders that qualify as minority-owned, small, or small disadvantaged businesses. As a result, we would not be eligible to perform as a prime contractor on those programs and would be restricted to a maximum of 49% of the work as a subcontractor on those programs. An increase in the amount of procurements under the Small Business Administration set-aside program may impact our ability to bid on new procurements as a prime contractor or restrict our ability to recompete on incumbent work that is placed in the set-aside program.

The potential implementation and operation of new financial management systems may have an adverse effect on our business and results of operations.

We, from time to time, modernize and upgrade our management systems. In particular, we are considering and have taken steps in preparation for the implementation of new financial management systems that would be designed to enhance our financial systems and cost accounting practices in order to modernize our financial infrastructure through minimizing manual processes, increasing automation, and providing enhanced business analytics. Preparing for implementation and operation of the new systems requires significant investment of human and financial resources. Should we implement the new systems, we would also expect to incur additional expenses and experience certain one-time impacts to profitability related to the roll-out and operation of the new financial systems, including costs related to training. In addition, any significant deficiency in the implementation or operation could have a material adverse effect on our ability to fulfill and invoice customer orders, apply cash receipts, place purchase orders with suppliers, and make cash disbursements, and could negatively impact data processing and electronic communications among business locations, which may have a material adverse effect on our business, consolidated financial condition or results of operations. We also face the challenge of supporting our legacy systems and implementing necessary upgrades to those systems to support routine government and financial audits while and after we implement our new systems.

Our work with government clients exposes us to additional risks inherent in the government contracting environment, which could reduce our revenue, disrupt our business, or otherwise materially adversely affect our results of operation.

U.S. government agencies routinely audit, review, and investigate government contracts and government contractors’ administrative processes and systems. These agencies review our performance on contracts, pricing practices, cost accounting practices, and compliance with applicable laws, regulations and standards, including applicable government cost accounting standards, as well as our contract costs, including allocated indirect costs. These agencies also review our compliance with government regulations and policies, and the DCAA audits, among other areas, the adequacy of our internal control systems and policies, including our Defense Federal Acquisition Regulation Supplement ("DFARS") required business systems, which is comprised of our purchasing, property, estimating, earned value, accounting and material management and accounting systems. These internal control systems could focus on significant elements of costs, such as executive compensation. Determination of a significant internal control deficiency by a government agency could result in increased payment withholding that might materially increase our accounts receivable days sales outstanding and adversely affect our cash flow. In particular, over time the DCMA has increased and may continue to increase the proportion of executive compensation that it deems unallowable and the size of the executive population whose compensation is disallowed, which will continue to materially and adversely affect our results of operations or financial condition including the requirement to carry an increased level of reserves. Recent legislation and regulations implementing new limitations on the amount of allowable executive compensation costs contribute to increased regulatory scrutiny of the allowability of employee compensation costs, which can lead to greater amounts of employee compensation cost being disallowed. We recognize as revenue, net of reserves, executive compensation that we determine, based on management's estimates, to be allowable; management's estimates in this regard are based on a number of factors that may change over time, including executive compensation survey data, our and other government contractors' experiences with the DCAA audit practices in our industry and relevant decisions of courts and boards of contract appeals. Any costs found to be unallowable under a contract will not be reimbursed, and any such costs already reimbursed must be refunded. Further, the amount of any such refund may exceed reserves established by management based on estimates and assumptions that are inherently uncertain. Moreover, if any of the administrative processes and business systems, some of which are currently certified as effective, are found not to comply with government imposed requirements, we may be subjected to increased government scrutiny and approval that could delay or otherwise adversely affect our ability to compete for or perform contracts or to be paid timely. Unfavorable U.S. government audit, review, or investigation results could subject us to civil or criminal penalties or administrative sanctions, require us to retroactively and prospectively adjust previously agreed to billing or pricing rates for our work, and could harm our reputation and relationships with our clients and impair our ability to be awarded new contracts, which could affect our future sales and profitability by preventing us, by operation of law or in practice, from receiving new government contracts for some period of time. In addition, if our invoicing system were found to be inadequate following an audit by the DCAA, our ability to directly invoice U.S. government payment offices could be eliminated. As a result, we would be required to submit each invoice to the DCAA for approval prior to

30

payment, which could materially increase our accounts receivable days sales outstanding and adversely affect our cash flow. In addition, proposed regulatory changes, if adopted, would require the Department of Defense’s contracting officers to impose contractual withholdings at no less than certain minimum levels based on assessments of a contractor’s business systems. An unfavorable outcome to an audit, review, or investigation by any U.S. government agency could materially and adversely affect our relationship with the U.S. government. If a government investigation uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeitures of profits, withholding of payments, suspension of payments, fines, and suspension or debarment from doing business with the U.S. government. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us. Provisions that we have recorded in our consolidated financial statements as a compliance reserve may not cover actual losses. Furthermore, the disallowance of any costs previously charged could directly and negatively affect our current results of operations for the relevant prior fiscal periods, and we could be required to repay any such disallowed amounts. Each of these results could materially and adversely affect our results of operations or financial condition.

In addition, we are currently considering and have taken steps in preparation for the implementation of new financial management systems, which would likely involve certain changes to our cost accounting practices. This may negatively impact our profitability. In particular, changes to our cost accounting practices could require us to estimate changes in costs for certain contracts at the time of implementation and make payments in connection with such estimates that could be material and not recoverable. To the extent we are unable to fully mitigate the costs associated with changes to our cost accounting practices if we implement the new systems, our business and financial results may be adversely affected.

A delay in the completion of the U.S. government’s budget process could result in a reduction in our backlog and have a material adverse effect on our revenue and operating results.

On an annual basis, the U.S. Congress must approve budgets that govern spending by each of the federal agencies we support. When the U.S. Congress is unable to agree on budget priorities, and thus is unable to pass the annual budget on a timely basis, the U.S. Congress typically enacts a continuing resolution. A continuing resolution allows government agencies to operate at spending levels approved in the previous budget cycle. Under a continuing resolution, funding may not be available for new projects. In addition, when government agencies operate on the basis of a continuing resolution, they may delay funding we expect to receive on contracts we are already performing. Any such delays would likely result in new business initiatives being delayed or canceled and a reduction in our backlog, and could have a material adverse effect on our revenue and operating results. In addition, a failure to complete the budget process and fund government operations pursuant to a continuing resolution may result in a federal government shutdown (such as that which occurred during government fiscal years 2014, 2018 and 2019). A shutdown may result in us incurring substantial costs without reimbursement under our contracts and the delay or cancellation of key programs or the delay of contract payments, which could have a material adverse effect on our revenue and operating results. In addition, when supplemental appropriations are required to operate the U.S. government or fund specific programs and passage of legislation needed to approve any supplemental appropriation bill is delayed, the overall funding environment for our business could be adversely affected.

Risks Related to Our Indebtedness

We have substantial indebtedness and may incur substantial additional indebtedness, which could adversely affect our financial health and our ability to obtain financing in the future as well as to react to changes in our business.

As of March 31, 2019, we had total indebtedness of approximately $1.8 billion and $499.0 million of availability under our revolving credit facility (the “Revolving Credit Facility”) and $400.0 million of availability under the Delayed Draw Facility (as defined below). We are able to, and may, incur additional indebtedness in the future, subject to the limitations contained in the agreements governing our indebtedness. Our substantial indebtedness could have important consequences to holders of our common stock, including:

▪ making it more difficult for us to satisfy our obligations with respect to our Secured Credit Facility, consisting of a $1,038 million term loan facility (“Term Loan A”), a $391 million term loan facility (“Term Loan B” and, together with Term Loan A, the “Term Loans”), a $500 million Revolving Credit Facility, with a sublimit for letters of credit of $100 million, and a $400.0 million delayed draw facility (the “Delayed Draw Facility”), which was fully drawn-down on April 23, 2019, our $350 million in aggregate principal amount of 5.125% Senior Notes due 2025 (the “Senior Notes”) and our other debt;

▪ limiting our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions or other general corporate requirements;

▪ requiring a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, acquisitions and other general corporate purposes;

▪ increasing our vulnerability to general adverse economic and industry conditions

31

▪ exposing us to the risk of increased interest rates as certain of our borrowings, including under the Secured Credit Facility, are at variable rates of interest;

▪ limiting our flexibility in planning for and reacting to changes in the industry in which we compete;

▪ placing us at a disadvantage compared to other, less leveraged competitors or competitors with comparable debt and more favorable terms and thereby affecting our ability to compete; and

▪ increasing our cost of borrowing.

Although the Secured Credit Facility and the indenture governing the Senior Notes contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and the additional indebtedness incurred in compliance with these restrictions could be substantial. These restrictions also will not prevent us from incurring obligations that do not constitute indebtedness. In addition, the Revolving Credit Facility provides for commitments of $500 million, which as of March 31, 2019, had availability of $499.0 million. Additionally, the used portion as it pertains to open standby letters of credit and bank guarantees totaled $1.0 million. Furthermore, subject to specified conditions, without the consent of the then-existing lenders (but subject to the receipt of commitments), the indebtedness under the Secured Credit Facility may be increased by up to (x) $400 million plus (y) an additional amount if, after giving pro forma effect to the incurrence of such additional amount and after giving effect to any acquisition consummated concurrently therewith and all other appropriate pro forma adjustment events, the consolidated net senior secured leverage ratio is equal to or less than 3.50:1.00. If new debt is added to our current debt levels, the related risks that we and the guarantors now face would increase and we may not be able to meet all our debt obligations, including the repayment of the Senior Notes.

We may not be able to generate sufficient cash to service our indebtedness and may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful.

Our ability to make scheduled payments on or refinance our debt obligations will depend on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to financial, business, legislative, regulatory and other factors beyond our control. We might not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness. For information regarding the risks to our business that could impair our ability to satisfy our obligations under our indebtedness, see “— Risks Related to Our Business.”

If our cash flows and capital resources are insufficient to fund our debt service obligations, we could face substantial liquidity problems and could be forced to reduce or delay investments and capital expenditures or to dispose of material assets or operations, seek additional debt or equity capital or restructure or refinance our indebtedness. We may not be able to effect any such alternative measures on commercially reasonable terms or at all and, even if successful, those alternative actions may not allow us to meet our scheduled debt service obligations.

The agreements governing our indebtedness restrict our ability to dispose of assets and use the proceeds from those dispositions and also restrict our ability to raise debt to be used to repay other indebtedness when it becomes due.

We may not be able to consummate those dispositions or to obtain proceeds in an amount sufficient to meet any debt service obligations then due. In addition, under the Secured Credit Facility, we are subject to mandatory prepayments of our Term Loans from a portion of our excess cash flows, which may be stepped down upon the achievement of specified first lien leverage ratios. To the extent that we are required to prepay any amounts under our Term Loans, we may have insufficient cash to make required principal and interest payments on other indebtedness.

Our inability to generate sufficient cash flows to satisfy our debt obligations, or to refinance our indebtedness on commercially reasonable terms or at all, would materially and adversely affect our financial condition and results of operations and our ability to satisfy our obligations under our indebtedness.

If we cannot make scheduled payments on our debt, we will be in default and lenders under our Secured Credit Facility and holders of the Senior Notes could declare all outstanding principal and interest to be due and payable, the lenders under the Revolving Credit Facility could terminate their commitments to loan money, the lenders could foreclose against the assets securing their loans and we could be forced into bankruptcy or liquidation. All of these events could result in you losing some or all of the value of your investment.

The terms of the agreements governing our indebtedness restrict our current and future operations, particularly our ability to respond to changes or to take certain actions, which could harm our long-term interests.

The Secured Credit Facility and the indenture governing the Senior Notes contain covenants that, among other things, impose significant operating and financial restrictions on us and limit our ability to engage in actions that may be in our long-term best interest, including restrictions on our ability to:

▪ incur additional indebtedness, guarantee indebtedness or issue disqualified stock or preferred stock;

32

▪ pay dividends on or make other distributions in respect of, or repurchase or redeem, our capital stock;

▪ prepay, redeem or repurchase subordinated indebtedness;

▪ make loans and investments;

▪ sell or otherwise dispose of assets;

▪ incur liens securing indebtedness;

▪ enter into transactions with affiliates;

▪ enter into agreements restricting our subsidiaries’ ability to pay dividends to us or the guarantors or make other intercompany transfers;

▪ consolidate, merge or sell all or substantially all of our or any guarantor’s assets;

▪ designate our subsidiaries as unrestricted subsidiaries; and

▪ enter into certain lines of business.

These covenants are subject to a number of important exceptions and qualifications. In addition, the restrictive covenants in the Secured Credit Facility require us to maintain a consolidated net total leverage ratio and a consolidated net interest coverage ratio that will each be tested at the end of each fiscal quarter. Our ability to satisfy that financial ratio test may be affected by events beyond our control.

A breach of the covenants under the agreements governing our indebtedness could result in an event of default under those agreements. Such a default may allow certain creditors to accelerate the related debt and may result in the acceleration of any other debt to which a cross-acceleration or cross-default provision applies. In addition, an event of default under the Secured Credit Facility would also permit the lenders under the Revolving Credit Facility to terminate all other commitments to extend further credit under that facility. Furthermore, if we were unable to repay the amounts due and payable under the Secured Credit Facility, those lenders could proceed against the collateral granted to them to secure that indebtedness. In the event the lenders accelerate the repayment of our borrowings, we may not have sufficient assets to repay that indebtedness.

As a result of all of these restrictions, we may be:

• limited in how we conduct our business;

• unable to raise additional debt or equity financing to operate during general economic or business downturns; or

• unable to compete effectively or to take advantage of new business opportunities.

These restrictions might hinder our ability to grow in accordance with our strategy.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Borrowings under the Secured Credit Facility are at variable rates of interest and expose us to interest rate risk. Interest rates are currently at historically low levels but increased in fiscal 2019. If interest rates continue to increase, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed remains the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease.

Based on Term Loans outstanding as of March 31, 2019 and assuming all revolving loans are fully drawn, and after considering interest rate swaps that fixed the interest rate on $600 million of principal of our variable rate debt each quarter point change in interest rates would result in a $3.7 million change in our projected annual interest expense on our indebtedness under the Secured Credit Facility. We have entered into interest rate swaps and may in the future enter into additional interest rate swaps, that involve the exchange of floating for fixed rate interest payments in order to reduce future interest rate volatility of our variable rate indebtedness. However, due to risks for hedging gains and losses and cash settlement costs, we may not elect to maintain such interest rate swaps, and any swaps may not fully mitigate our interest rate risk.

In addition, a transition away from the London Interbank Offering Rate (“LIBOR”) as a benchmark for establishing the applicable interest rate may affect the cost of servicing our debt under the Secured Credit Facility and the Revolving Credit Facility. As of March 31, 2019, we had $1,759.8 million outstanding under the Secured Credit Facility and $499.0 million of availability under the Revolving Credit Facility, each of which incurs interest based on LIBOR. The Financial Conduct Authority of the United Kingdom has announced that it plans to phase out LIBOR by the end of calendar year 2021. Although these borrowing arrangements provide for alternative base rates, such alternative base rates may or may not be related to LIBOR, and the consequences of the phase out of LIBOR cannot be entirely predicted at this time. For example, if any alternative base rate or means of calculating interest with respect to our outstanding variable rate indebtedness leads to an

33

increase in the interest rates charged, it could result in an increase in the cost of such indebtedness, impact our ability to refinance some or all of our existing indebtedness or otherwise have a material adverse impact on our business, financial condition and results of operations.

A downgrade, suspension or withdrawal of the rating assigned by a rating agency to us or our indebtedness could make it more difficult for us to obtain additional debt financing in the future.

Our indebtedness has been rated by nationally recognized rating agencies and may in the future be rated by additional rating agencies. We cannot assure you that any rating assigned to us or our indebtedness will remain for any given period of time or that a rating will not be lowered or withdrawn entirely by a rating agency if, in that rating agency’s judgment, circumstances relating to the basis of the rating, such as adverse changes in our business, so warrant. Any downgrade, suspension or withdrawal of a rating by a rating agency (or any anticipated downgrade, suspension or withdrawal) could make it more difficult or more expensive for us to obtain additional debt financing in the future.

Risks Related to Our Common Stock

Booz Allen Holding is a holding company with no operations of its own, and it depends on its subsidiaries for cash to fund all of its operations and expenses, including to make future dividend payments, if any.

The operations of Booz Allen Holding are conducted almost entirely through its subsidiaries and its ability to generate cash to meet its debt service obligations or to pay dividends is highly dependent on the earnings and the receipt of funds from its subsidiaries via dividends or intercompany loans. Further, the Secured Credit Facility and indenture governing the Senior Notes significantly restricts the ability of our subsidiaries to pay dividends or otherwise transfer assets to us. In addition, Delaware law may impose requirements that may restrict our ability to pay dividends to holders of our common stock.

Our financial results may vary significantly from period to period as a result of a number of factors many of which are outside our control, which could cause the market price of our Class A Common Stock to fluctuate.

Our financial results may vary significantly from period to period in the future as a result of many external factors that are outside of our control. Factors that may affect our financial results and that could cause the market price of our outstanding securities, including our Class A Common Stock, to fluctuate include those listed in this “Risk Factors” section and others such as:

• any cause of reduction or delay in U.S. government funding;

• fluctuations in revenue earned on existing contracts;

• commencement, completion, or termination of contracts during a particular period;

• a potential decline in our overall profit margins if our other direct costs and subcontract revenue grow at a faster rate than labor-related revenue;

• strategic decisions by us or our competitors, such as changes to business strategy, strategic investments, acquisitions, divestitures, spin offs, and joint ventures;

• a change in our contract mix to less profitable contracts;

• changes in policy or budgetary measures that adversely affect U.S. government contracts in general;

• variable purchasing patterns under U.S. government GSA schedules, blanket purchase agreements, which are agreements that fulfill repetitive needs under GSA schedules, and IDIQ contracts;

• changes in demand for our services and solutions;

• fluctuations in the degree to which we are able to utilize our professionals;

• seasonality associated with the U.S. government’s fiscal year;

• an inability to utilize existing or future tax benefits for any reason, including a change in law;

• alterations to contract requirements; and

• adverse judgments or settlements in legal disputes.

We cannot assure you that we will pay special or regular dividends on our stock in the future.

The Board of Directors has authorized and declared a regular quarterly dividend for each quarter in the last several years. The Board of Directors has also authorized and declared special cash dividends from time to time. The declaration of any future dividends and the establishment of the per share amount, record dates and payment dates for any such future dividends are subject to the discretion of the Board of Directors taking into account future earnings, cash flows, financial requirements

34

and other factors. There can be no assurance that the board of directors will declare any dividends in the future. To the extent that expectations by market participants regarding the potential payment, or amount, of any special or regular dividend prove to be incorrect, the price of our common stock may be materially and negatively affected and investors that bought shares of our common stock based on those expectations may suffer a loss on their investment. Further, to the extent that we declare a regular or special dividend at a time when market participants hold no such expectations or the amount of any such dividend exceeds current expectations, the price of our common stock may increase and investors that sold shares of our common stock prior to the record date for any such dividend may forego potential gains on their investment.

Fulfilling our obligations incident to being a public company, including with respect to the requirements of and related rules under the Sarbanes Oxley Act of 2002, is expensive and time consuming and any delays or difficulty in satisfying these obligations could have a material adverse effect on our future results of operations and our stock price.

As a public company, the Sarbanes-Oxley Act of 2002 and the related rules and regulations of the SEC, as well as the New York Stock Exchange rules, require us to implement various corporate governance practices and adhere to a variety of reporting requirements and complex accounting rules. Compliance with these public company obligations requires us to devote significant management time and place significant additional demands on our finance and accounting staff and on our management systems, including our financial, accounting, and information systems. We have accounting and financial staff with appropriate public company reporting experience and technical accounting knowledge. Other expenses associated with being a public company include increased auditing, accounting, and legal fees and expenses, investor relations expenses, increased directors’ fees and director and officer liability insurance costs, registrar and transfer agent fees, listing fees, as well as other expenses.

In particular, the Sarbanes-Oxley Act of 2002 requires us to document and test the effectiveness of our internal control over financial reporting in accordance with an established internal control framework, and to report on our conclusions as to the effectiveness of our internal controls. It also requires an independent registered public accounting firm to test our internal control over financial reporting and report on the effectiveness of such controls. In addition, we are required under the Exchange Act to maintain disclosure controls and procedures and internal control over financial reporting. Because of inherent limitations in any internal control environment, there can be no assurance that all control issues and instances of fraud, errors or misstatements, if any, within our company have been or will be detected on a timely basis. Such deficiencies could result in the correction or restatement of financial statements of one or more periods. Any failure to maintain effective controls or implement new or improved controls, or difficulties encountered in their implementation, could harm our operating results or cause us to fail to meet our reporting obligations. We also rely on third parties for certain calculations and other information that support our accounting and financial reporting, which includes reports from such organizations on their controls and systems that are used to generate this information. The calculations and other information that we receive from such third parties may not be accurate, and we may not receive adequate or timely information related to internal control failures occurring at these organizations. Any failure by such third parties to provide us with accurate information or implement and maintain effective controls may cause us to be unable to meet our reporting obligations as a publicly traded company. In addition, if we implement new financial management systems, we could experience deficiencies in its operation that could have an adverse effect on the effectiveness of our internal control over financial reporting.

If we are unable to conclude that we have effective internal control over financial reporting, or if our independent registered public accounting firm is unable to provide us with an unqualified report regarding the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our consolidated financial statements, which could result in a decrease in the value of our common stock. Failure to comply with the Sarbanes-Oxley Act of 2002 could potentially subject us to sanctions or investigations by the SEC, the New York Stock Exchange, or other regulatory authorities.

Provisions in our organizational documents and in the Delaware General Corporation Law may prevent takeover attempts that could be beneficial to our stockholders.

Our amended and restated certificate of incorporation and amended and restated bylaws include a number of provisions that may have the effect of delaying, deterring, preventing, or rendering more difficult a change in control of Booz Allen Holding that our stockholders might consider in their best interests. These provisions include:

• establishment of a classified Board, with staggered terms;

• granting to the Board the sole power to set the number of directors and to fill any vacancy on the Board;

• limitations on the ability of stockholders to remove directors;

• granting to the Board the ability to designate and issue one or more series of preferred stock without stockholder approval, the terms of which may be determined at the sole discretion of the Board;

• a prohibition on stockholders from calling special meetings of stockholders;

35

• the establishment of advance notice requirements for stockholder proposals and nominations for election to the Board at stockholder meetings;

• requiring approval of two-thirds of stockholders to amend the bylaws; and

• prohibiting our stockholders from acting by written consent.

In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which imposes additional requirements regarding mergers and other business combinations. These provisions may prevent our stockholders from receiving the benefit from any premium to the market price of our common stock offered by a bidder in a takeover context. Even in the absence of a takeover attempt, the existence of these provisions may adversely affect the prevailing market price of our common stock if the provisions are viewed as discouraging takeover attempts in the future.

Our amended and restated certificate of incorporation and amended and restated by-laws may also make it difficult for stockholders to replace or remove our management. These provisions may facilitate management entrenchment that may delay, deter, render more difficult, or prevent a change in our control, which may not be in the best interests of our stockholders.

The market for our Class A Common Stock may be adversely affected by the performance of other companies in the government services market.

In addition to factors that may affect our financial results and operations, the price of our Class A Common Stock may be impacted by the financial performance and outlook of other companies in the government services market. While certain factors may affect all participants in the markets in which we operate, such as U.S. government spending conditions and changes in rules and regulations applicable to government contractors, the market for our Class A Common Stock may be adversely affected by financial results or negative events only affecting other market participants or financial results of such participants. While such events or results may not impact or be indicative of our current or future performance, the price of our securities may nonetheless be adversely affected as a result thereof.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

We do not own any facilities or real estate. Our corporate headquarters is located at 8283 Greensboro Drive, McLean, Virginia 22102. We lease other operating offices and facilities throughout North America, and a limited number of overseas locations. Our principal offices outside of McLean, Virginia include: Annapolis Junction, Maryland; Rockville, Maryland; Laurel, Maryland; San Diego, California; Herndon, Virginia; Charleston, South Carolina; Arlington, Virginia; Alexandria, Virginia; and Washington, D.C. We have a number of Sensitive Compartmented Information Facilities, which are enclosed areas within buildings that are used to perform classified work for the U.S. Intelligence Community. Many of our employees are located in facilities provided by the U.S. government. The total square footage of our leased offices and facilities is approximately 2.65 million square feet. We believe our facilities meet our current needs.

Item 3. Legal Proceedings

The Company is involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with clients and contractors, intellectual property disputes, and other business matters. These legal proceedings seek various remedies, including claims for monetary damages in varying amounts, none of which are considered material, or are unspecified as to amount. Although the outcome of any such matter is inherently uncertain and may be materially adverse, based on current information, we do not expect any of the currently ongoing audits, reviews, investigations, or litigation to have a material adverse effect on our financial condition and results of operations. As of March 31, 2019 and 2018, there were no material amounts accrued in the consolidated financial statements related to these proceedings.

Six former officers and stockholders who had departed the company prior to the acquisition of the Company by the Carlyle Group (the "Carlyle Acquisition") have filed a total of nine suits in various jurisdictions, with original filing dates ranging from July 3, 2008 through December 15, 2009, against us and certain of our current and former directors and officers. Three of these suits were amended on July 2, 2010 and then further amended into one consolidated complaint on September 7, 2010. Another two of the original nine suits were consolidated into one complaint on September 24, 2014. Each of the suits arises out of the Carlyle Acquisition and alleges that the former stockholders are entitled to certain payments that they would have received if they had held their stock at the time of the Carlyle Acquisition. Some of the suits also allege that the acquisition price paid to stockholders was insufficient. The various suits assert claims for breach of contract, tortious

36

interference with contract, breach of fiduciary duty, civil Racketeer Influenced and Corrupt Organizations Act, or RICO, violations, violations of the Employee Retirement Income Security Act, or ERISA, and/or securities and common law fraud. Three of these suits have been dismissed with all appeals exhausted. The two suits that were consolidated into one action on September 24, 2014 were settled on April 16, 2015. One of the remaining suits has been dismissed by the United States District Court for the Southern District of California and such dismissal was upheld by the United States Court of Appeals for the Ninth Circuit. The plaintiff in this suit subsequently filed a Petition for Writ of Certiorari to the United States Supreme Court, which was denied by the United States Supreme Court on January 9, 2017. The other three remaining suits that were previously consolidated on September 7, 2010 have been dismissed by the United States District Court for the Southern District of New York and were on appeal before the United States Court of Appeals for the Second Circuit. On July 13, 2017, the United States Court of Appeals for the Second Circuit affirmed the ruling of the United States District Court for the Southern District of New York, except for one plaintiff's securities fraud claim, which was remanded to the United States District Court for the Southern District of New York to give the plaintiff, Paul Kocourek, leave to file another amended complaint to attempt to plead a securities fraud claim. On April 6, 2018, the plaintiff filed an amended complaint in which Mr. Kocourek, individually, as Trustee of the Paul Kocourek Trust and on behalf of a putative class, alleges that the Company and certain former officers and directors violated Sections 10(b), 20(a) and 14(e) of the Exchange Act. On April 25, 2018, the court entered an order postponing the deadline within which the defendants must answer or move to dismiss the amended complaint. A lead plaintiff has not been appointed. On August 2, 2018, the defendants filed a motion to dismiss the amended complaint. On September 17, 2018, the plaintiff filed an opposition to the defendants’ motion to dismiss the amended complaint. The defendants filed their reply to plaintiff's opposition on October 17, 2018.

As of March 31, 2019, the aggregate alleged damages that will be sought in the remaining suit is unknown. As of March 31, 2019, although the outcome of any of these cases is inherently uncertain and may be materially adverse, based on current information, we do not expect them to have a material adverse effect on our financial condition and results of operations.

On June 7, 2017, Booz Allen Hamilton Inc. was informed that the U.S. Department of Justice (DOJ) is conducting a civil and criminal investigation of the Company. In connection with the investigation, the DOJ has requested information from the Company relating to certain elements of the Company's cost accounting and indirect cost charging practices with the U.S. government. Since learning of the investigation, the Company has engaged a law firm experienced in these matters to represent the Company in connection with this matter and respond to the government's requests. As is commonly the case with this type of matter, the Company has also been in contact with other regulatory agencies and bodies, including the SEC, which notified the Company that it is conducting an investigation that the Company believes relates to the matters that are also the subject of the DOJ's investigation. The Company may receive additional regulatory or governmental inquiries related to the matters that are subject of the DOJ's investigation. In accordance with the Company's practice, the Company is cooperating with all relevant government parties. The total cost associated with these matters will depend on many factors, including the duration of these matters and any related findings. At this stage, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with these matters.

On June 19, 2017, a purported stockholder of the Company filed a putative class action lawsuit in the United States District Court for the Eastern District of Virginia styled Langley v. Booz Allen Hamilton Holding Corp., No. 17-cv-00696 naming the Company, its Chief Executive Officer and its Chief Financial Officer as defendants purportedly on behalf of all purchases of the Company's securities from May 19, 2016 through June 15, 2017. On September 5, 2017, the court named two lead plaintiffs, and on October 20, 2017, the lead plaintiffs filed a consolidated amended complaint. The complaint asserts claims under Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder, alleging misrepresentations or omissions by the Company purporting to relate to matters that are the subject of the DOJ investigation described above. The plaintiffs seek to recover from the Company and the individual defendants an unspecified amount of damages. The Company believes the suit lacks merit and intends to defend against the lawsuit. Motions to dismiss were argued on January 12, 2018, and on February 8, 2018, the court dismissed the amended complaint in its entirety without prejudice. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

On November 13, 2017, a Verified Shareholder Derivative Complaint was filed in the United States District Court for the District of Delaware styled Celine Thum v. Rozanski et al., C.A. No. 17-cv-01638, naming the Company as a nominal defendant and numerous current and former officers and directors as defendants. The complaint asserts claims for breach of fiduciary duties, unjust enrichment, waste of corporate assets, abuse of control, gross mismanagements, and violations of Sections 14(a), 10(b), and 20(a) of the Exchange Act, purportedly relating to matters that are the subject of the DOJ investigation described above. The parties have stipulated to a stay of the proceedings pending the outcome of the securities litigation (described above), which the court ordered on January 24, 2018. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

On April 1, 2018, the Company adopted Topic 606, Revenue from Contracts with Customers, using the full retrospective transition method and adopted retrospectively ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost andNet Periodic Postretirement Benefit Cost. Fiscal 2019, Fiscal 2018 and Fiscal 2017 results reflect the impact of the adoption of the two standards (See Note 2 in our consolidated financial statements). Fiscal 2016 and Fiscal 2015 information has not been restated for the adoption of Topic 606 and ASU 2017-07, in accordance with the standard, and is therefore not comparable to the results from Fiscal 2019, Fiscal 2018 and Fiscal 2017.

(1) Basic earnings per share for the Company has been computed using the weighted average number of shares of Class A Common Stock, Class B Non- Voting Common Stock, and Class C Restricted Common Stock outstanding during the period. The Company’s diluted earnings per share has been computed using the weighted average number of shares of Class A Common Stock, Class B Non-Voting Common Stock, and Class C Restricted Common Stock including the dilutive effect of outstanding common stock options and other stock-based awards. For the purposes of calculating basic and diluted earnings per share, the Company has utilized the two class method, given non-forfeitable dividends declared on unvested Class A Restricted Common Stock. The weighted average number of Class E Special Voting Common Stock has not been included in the calculation of either basic earnings per share or diluted earnings per share due to the terms of such common stock.

Financial and Other Highlights

Effective April 1, 2018, the Company adopted Accounting Standard Codification (ASC) No. 606, Revenue from Contracts with Customers (Topic 606), and Accounting Standard Updates (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, using the full retrospective method. All amounts, percentages and disclosures set forth in this Form 10-K for fiscal 2019, 2018 and 2017 reflect these changes. See Note 2 to our accompanying consolidated financial statements for more information on the impact of the adoption of these accounting standards on revenue and operating income.

During fiscal 2019, the Company generated its highest annual revenue since its initial public offering and reported increases in headcount and backlog for the year. Revenue increased 8.7% from fiscal 2018 to fiscal 2019 primarily driven by continued strength in client demand, which led to increased client staff headcount, and an increase in client staff labor, as well as improved contract performance. Revenue also benefited from higher billable expenses as compared to the prior year.

Operating income increased 15.9% to $602.4 million in fiscal 2019 from $519.7 million in fiscal 2018, which reflects an increase in operating margin to 9.0% from 8.4% in the comparable year. The increase in operating income was primarily driven by the same factors driving revenue growth as well as improved contract performance. During fiscal 2019 the Company also benefited from an $11.2 million reduction in expense as a result of an amendment and associated revaluation of our long term disability plan liability. The Company also incurred incremental legal costs during fiscal 2018 and 2019 in response to the U.S. Department of Justice investigation and matters which purport to relate to the investigation, a portion of which was offset by the receipt of insurance reimbursements. We expect to incur additional costs in the future. Based on the information currently available, the Company is not able to reasonably estimate the expected long-term incremental legal costs or amounts that may be reimbursed associated with this investigation and these related matters.

Non-GAAP Measures

We publicly disclose certain non-GAAP financial measurements, including Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, and Adjusted Diluted Earnings Per Share, or Adjusted Diluted EPS, because management uses these measures for business planning purposes, including to manage our business against internal projected results of operations and measure our performance. We view Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, and Adjusted Diluted EPS as measures of our core operating business, which exclude the impact of the items detailed below, as these items are generally not operational in nature. These non-GAAP measures also provide another basis for comparing period to period results by excluding potential differences caused by non-operational and unusual or non-recurring items. In addition, we use Revenue, Excluding Billable Expenses because it provides management useful information about the Company's operating performance by excluding the impact of costs that are not indicative of the level of productivity of our consulting staff headcount and our overall direct labor, which management believes provides useful information to our investors about our core operations. We also utilize and discuss Free Cash Flow, because management uses this measure for business planning purposes, measuring the cash generating ability of the operating business, and measuring liquidity generally. We present these supplemental measures because we believe that these measures provide investors and securities analysts with important supplemental information with which to evaluate our performance, long-term earnings potential, or liquidity, as applicable, and to enable them to assess our performance on the same basis as management. These supplemental performance measurements may vary from and may not be comparable to similarly titled measures by other companies in our industry. Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow are not recognized measurements under accounting principles generally accepted in the United States, or GAAP, and when analyzing our performance or liquidity, as applicable, investors should (i) evaluate each adjustment in our reconciliation of revenue to Revenue, Excluding Billable Expenses, operating income to Adjusted Operating Income, net income to Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income and Adjusted Diluted Earnings Per Share, and net cash provided by operating activities to Free Cash Flow, (ii) use Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, and Adjusted Diluted EPS in addition to, and not as an alternative to, revenue, operating income, net income or diluted EPS, as measures of operating results, each as defined under GAAP and (iii) use Free Cash Flow in addition to, and not as an alternative to, net cash provided by operating activities as a measure of liquidity, each as defined under GAAP. We have defined the aforementioned non-GAAP measures as follows:

• "Revenue, Excluding Billable Expenses" represents revenue less billable expenses. We use Revenue, Excluding Billable Expenses because it provides management useful information about the Company's operating performance by excluding the impact of costs that are not indicative of the level of productivity of our consulting staff headcount and our overall direct labor, which management believes provides useful information to our investors about our core operations.

• "Adjusted Operating Income" represents operating income before: (i) adjustments related to the amortization of intangible assets resulting from the acquisition of our Company by The Carlyle Group (the “Carlyle Acquisition”), and (ii) transaction costs, fees, losses, and expenses, including fees associated with debt prepayments. We prepare Adjusted Operating Income to eliminate the impact of items we do not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary, or non-recurring nature or because they result from an event of a similar nature.

• "Adjusted EBITDA" represents net income before income taxes, net interest and other expense and depreciation and amortization and before certain other items, including transaction costs, fees, losses, and expenses, including fees associated with debt prepayments. “Adjusted EBITDA Margin on Revenue” is calculated as Adjusted EBITDA divided by revenue. "Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses" is calculated as Adjusted EBITDA divided by Revenue, Excluding Billable Expenses. The Company prepares Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, and Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses to eliminate the impact of items it does not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary or non-recurring nature or because they result from an event of a similar nature.

• "Adjusted Net Income" represents net income before: (i) adjustments related to the amortization of intangible assets resulting from the Carlyle Acquisition, (ii) transaction costs, fees, losses, and expenses, including fees associated with debt prepayments, (iii) amortization or write-off of debt issuance costs and write-off of original issue discount, (iv) release of income tax reserves, and (v) re-measurement of deferred tax assets and

45

liabilities as a result of the Tax Cuts and Jobs Act (the "2017 Tax Act") in each case net of the tax effect where appropriate calculated using an assumed effective tax rate. We prepare Adjusted Net Income to eliminate the impact of items, net of tax, we do not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary, or non-recurring nature or because they result from an event of a similar nature. We view net income excluding the impact of the re-measurement of the Company's deferred tax assets and liabilities as a result of the 2017 Tax Act as an important indicator of performance consistent with the manner in which management measures and forecasts the Company's performance and the way in which management is incentivized to perform.

• "Adjusted Diluted EPS" represents diluted EPS calculated using Adjusted Net Income as opposed to net income. Additionally, Adjusted Diluted EPS does not contemplate any adjustments to net income as required under the two-class method as disclosed in the footnotes to the consolidated financial statements.

• "Free Cash Flow" represents the net cash generated from operating activities less the impact of purchases of property and equipment.

46

Below is a reconciliation of Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow to the most directly comparable financial measure calculated and presented in accordance with GAAP.

Factors and Trends Affecting Our Results of Operations

Our results of operations have been, and we expect them to continue to be, affected by the following factors, which may cause our future results of operations to differ from our historical results of operations discussed under “— Results of Operations.”

Business Environment and Key Trends in Our Markets

We believe that the following trends and developments in the U.S. government services industry and our markets may influence our future results of operations:

• uncertainty around the timing, extent, nature and effect of Congressional and other U.S. government actions to approve funding of the U.S. government, address budgetary constraints, including caps on the discretionary budget for defense and non-defense departments and agencies, as established by the Bipartisan Budget Control Act of 2011 ("BCA") and subsequently adjusted by the American Tax Payer Relief Act of 2012, the Bipartisan Budget Act of 2013, the Bipartisan Budget Act of 2015 and the Bipartisan Budget Act of 2018, and address the ability of Congress to determine how to allocate the available budget authority and pass appropriations bills to fund both U.S. government departments and agencies that are, and those that are not, subject to the caps;

• budget deficits and the growing U.S. national debt increasing pressure on the U.S. government to reduce federal spending across all federal agencies together with associated uncertainty about the size and timing of those reductions;

• cost-cutting and efficiency initiatives, current and future budget restrictions, continued implementation of Congressionally mandated automatic spending cuts and other efforts to reduce U.S. government spending could cause clients to reduce or delay funding for orders for services or invest appropriated funds on a less consistent or rapid basis or not at all, particularly when considering long-term initiatives and in light of uncertainty around Congressional efforts to approve funding of the U.S. government and to craft a long-term agreement on the U.S. government's ability to incur indebtedness in excess of its current limits and generally in the current political environment, there is a risk that clients will not issue task orders in sufficient volume to reach current contract ceilings, alter historical patterns of contract awards, including the typical increase in the award of task orders or completion of other contract actions by the U.S. government in the period before the end of the U.S. government's fiscal year on September 30, delay requests for new proposals and contract awards, rely on short-term extensions and funding of current contracts, or reduce staffing levels and hours of operation;

• delays in the completion of future U.S. government’s budget processes, which have in the past and could in the future delay procurement of the products, services, and solutions we provide;

48

• changes in the relative mix of overall U.S. government spending and areas of spending growth, with lower spending on homeland security, intelligence, defense-related programs as certain overseas operations end, and continued increased spending on cybersecurity, Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR), advanced analytics, technology integration and healthcare;

• legislative and regulatory changes to limitations on the amount of allowable executive compensation permitted under flexibly priced contracts following implementation of interim rules adopted by federal agencies pursuant to the Bipartisan Budget Act of 2013, which substantially further reduce the amount of allowable executive compensation under these contracts and extend these limitations to a larger segment of our executives and our entire contract base;

• efforts by the U.S. government to address organizational conflicts of interest and related issues and the impact of those efforts on us and our competitors;

• increased audit, review, investigation and general scrutiny by U.S. government agencies of government contractors' performance under U.S. government contracts and compliance with the terms of those contracts and applicable laws;

• the federal focus on refining the definition of “inherently governmental” work, including proposals to limit contractor access to sensitive or classified information and work assignments, which will continue to drive pockets of insourcing in various agencies, particularly in the intelligence market;

• negative publicity and increased scrutiny of government contractors in general, including us, relating to U.S. government expenditures for contractor services and incidents involving the mishandling of sensitive or classified information;

• U.S. government agencies awarding contracts on a technically acceptable/lowest cost basis, which could have a negative impact on our ability to win certain contracts;

• increased competition from other government contractors and market entrants seeking to take advantage of certain of the trends identified above, and industry trend towards consolidation, which may result in the emergence of companies that are better able to compete against us;

• cost-cutting and efficiency and effectiveness efforts by U.S. civilian agencies with a focus on increased use of performance measurement, “program integrity” efforts to reduce waste, fraud and abuse in entitlement programs, and renewed focus on improving procurement practices for and interagency use of IT services, including through the use of cloud based options and data center consolidation;

• restrictions by the U.S. government on the ability of federal agencies to use lead system integrators, in response to cost, schedule and performance problems with large defense acquisition programs where contractors were performing the lead system integrator role;

• increasingly complex requirements of the Department of Defense and the U.S. intelligence community, including cybersecurity, managing federal health care cost growth and focus on reforming existing government regulation of various sectors of the economy, such as financial regulation and healthcare; and

• increasing small business regulations across the Department of Defense and civilian agency clients continue to gain traction, agencies are required to meet high small business set aside targets, and large business prime contractors are required to subcontract in accordance with considerable small business participation goals necessary for contract award.

Sources of Revenue

Substantially all of our revenue is derived from services provided under contracts and task orders with the U.S. government, primarily by our consulting staff and, to a lesser extent, our subcontractors. Funding for our contracts and task orders is generally linked to trends in budgets and spending across various U.S. government agencies and departments. We provide services under a large portfolio of contracts and contract vehicles to a broad client base, and we believe that our diversified contract and client base lessens potential volatility in our business; however, a reduction in the amount of services that we are contracted to provide to the U.S. government or any of our significant U.S. government clients could have a material adverse effect on our business and results of operations. In particular, the Department of Defense is one of our significant clients, and the BCA (as amended by the American Taxpayer Relief Act of 2012, the Bipartisan Budget Act of 2013, the Bipartisan Budget Act of 2015, and the Bipartisan Act of 2018), provides for automatic spending cuts (referred to as sequestration) totaling approximately $1.2 trillion between 2013 and 2021, including an estimated $500 billion in federal defense spending cuts over this time period. The Bipartisan Budget Act of 2018 raised BCA spending caps on defense spending

49

by $80 billion for fiscal 2018, and $85 billion for fiscal 2019. For non-defense funding, the Bipartisan Budget Act of 2018 raised BCA spending caps by $63 billion for fiscal 2018 and $67 billion for fiscal 2019. While the American Taxpayer Relief Act of 2012, the Bipartisan Budget Act of 2013, the Bipartisan Budget Act of 2015, and the Bipartisan Budget Act of 2018 all negated and raised budget limits put in place by the BCA for both defense and non-defense spending, those spending limits are due to return in fiscal 2020, and absent another budget deal, could result in significant cuts to the budget levels allowed by the Bipartisan Budget Act of 2018. This could result in a commensurate reduction in the amount of services that we are contracted to provide to the Department of Defense and could have a material adverse effect on our business and results of operations, and given the uncertainty of when and how these automatic reductions required by the BCA may return and/or be applied, we are unable to predict the nature or magnitude of the potential adverse effect.

Contract Types

We generate revenue under the following three basic types of contracts:

• Cost-Reimbursable Contracts. Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract, up to a ceiling based on the amount that has been funded, plus a fixed fee or award fee. As we increase or decrease our spending on allowable costs, our revenue generated on cost-reimbursable contracts will increase, up to the ceiling and funded amounts, or decrease, respectively. We generate revenue under two general types of cost-reimbursable contracts: cost-plus-fixed-fee and cost-plus-award-fee, both of which reimburse allowable costs and provide for a fee. The fee under each type of cost-reimbursable contract is generally payable upon completion of services in accordance with the terms of the contract. Cost-plus-fixed-fee contracts offer no opportunity for payment beyond the fixed fee. Cost-plus-award-fee contracts also provide for an award fee that varies within specified limits based upon the client’s assessment of our performance against a predetermined set of criteria, such as targets for factors like cost, quality, schedule, and performance.

• Time-and-Materials Contracts. Under contracts in this category, we are paid a fixed hourly rate for each direct labor hour expended, and we are reimbursed for billable material costs and billable out-of-pocket expenses inclusive of allocable indirect costs. We assume the financial risk on time-and-materials contracts because our costs of performance may exceed negotiated hourly rates. To the extent our actual direct labor, including allocated indirect costs, and associated billable expenses decrease or increase in relation to the fixed hourly billing rates provided in the contract, we will generate more or less profit, respectively, or could incur a loss.

• Fixed-Price Contracts. Under a fixed-price contract, we agree to perform the specified work for a predetermined price. To the extent our actual direct and allocated indirect costs decrease or increase from the estimates upon which the price was negotiated, we will generate more or less profit, respectively, or could incur a loss. Some fixed-price contracts have a performance-based component, pursuant to which we can earn incentive payments or incur financial penalties based on our performance. Fixed-price level of effort contracts require us to provide a specified level of effort (i.e., labor hours), over a stated period of time, for a fixed price.

The amount of risk and potential reward varies under each type of contract. Under cost-reimbursable contracts, there is limited financial risk, because we are reimbursed for all allowable costs up to a ceiling. However, profit margins on this type of contract tend to be lower than on time-and-materials and fixed-price contracts. Under time-and-materials contracts, we are reimbursed for the hours worked using the predetermined hourly rates for each labor category. In addition, we are typically reimbursed for other contract direct costs and expenses at cost. We assume financial risk on time-and-materials contracts because our labor costs may exceed the negotiated billing rates. Profit margins on well-managed time-and-materials contracts tend to be higher than profit margins on cost-reimbursable contracts as long as we are able to staff those contracts with people who have an appropriate skill set. Under fixed-price contracts, we are required to deliver the objectives under the contract for a predetermined price. Compared to time-and-materials and cost-reimbursable contracts, fixed-price contracts generally offer higher profit margin opportunities because we receive the full benefit of any cost savings but generally involve greater financial risk because we bear the impact of any cost overruns. In the aggregate, the contract type mix in our revenue for any given period will affect that period's profitability. Changes in contract type as a result of re-competes and new business could influence the percentage/mix in unanticipated ways.

50

The table below presents the percentage of total revenue for each type of contract:

	Fiscal Year Ended March 31,
	2019	2018	2017
Cost-reimbursable	53%	51%	50%
Time-and-materials	24%	25%	26%
Fixed-price	23%	24%	24%

Note: Upon the adoption of Topic 606 in fiscal 2019, the contract type descriptions noted above have been aligned to the Revenue by Contract Type descriptions found in Note 3 to our accompanying consolidated financial statements.

Contract Diversity and Revenue Mix

We provide services to our clients through a large number of single award contracts, contract vehicles, and multiple award contract vehicles. Most of our revenue is generated under indefinite delivery/indefinite quantity, or IDIQ, contract vehicles, which include multiple award government wide acquisition contract vehicles, or GWACs, and General Services Administration Multiple Award Schedule Contracts, or GSA schedules, and certain single award contracts. GWACs and GSA schedules are available to all U.S. government agencies. Any number of contractors typically compete under multiple award IDIQ contract vehicles for task orders to provide particular services, and we earn revenue under these contract vehicles only to the extent that we are successful in the bidding process for task orders. No single task order under any IDIQ contract represented more than 3.8% of our revenue in fiscal 2019. No single definite contract accounted for more than 2.8% of our revenue in fiscal 2019.

We generate revenue under our contracts and task orders through our provision of services as both a prime contractor and subcontractor, as well as from the provision of services by subcontractors under contracts and task orders for which we act as the prime contractor. For fiscal 2019, 2018, and 2017, 92%, 91%, and 91%, respectively, of our revenue was generated by contracts and task orders for which we served as a prime contractor; 8%, 9%, and 9%, respectively, of our revenue was generated by contracts and task orders for which we served as a subcontractor; and approximately 24%, 25%, and 25%, respectively, of our revenue was generated by services provided by our subcontractors. The mix of these types of revenue affects our operating margin. Substantially all of our operating margin is derived from direct consulting staff labor as the portion of our operating margin derived from fees we earn on services provided by our subcontractors is not significant. We view growth in direct consulting staff labor as the primary driver of earnings growth. Direct consulting staff labor growth is driven by consulting staff headcount growth, after attrition, and total backlog growth.

Our People

Revenue from our contracts is derived from services delivered by consulting staff and, to a lesser extent, from our subcontractors. Our ability to hire, retain, and deploy talent with skills appropriately aligned with client needs is critical to our ability to grow our revenue. We continuously evaluate whether our talent base is properly sized and appropriately compensated and contains an optimal mix of skills to be cost competitive and meet the rapidly evolving needs of our clients. We seek to achieve that result through recruitment and management of capacity and compensation. As of March 31, 2019, 2018, and 2017, we employed approximately 26,100, 24,600, and 23,300 people, respectively, of which approximately 23,400, 22,100, and 21,000, respectively, were consulting staff.

Contract Backlog

We define backlog to include the following three components:

• Funded Backlog. Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts.

• Unfunded Backlog. Unfunded backlog represents the revenue value of orders (including optional orders) for services under existing contracts for which funding has not been appropriated or otherwise authorized.

• Priced Options. Priced contract options represent 100% of the revenue value of all future contract option periods under existing contracts that may be exercised at our clients’ option and for which funding has not been appropriated or otherwise authorized.

Our backlog does not include contracts that have been awarded but are currently under protest and also does not include any task orders under IDIQ contracts, except to the extent that task orders have been awarded to us under those contracts.

51

The following table summarizes the value of our contract backlog at the respective dates presented:

	Fiscal Year Ended March 31,
	2019		2018		2017
	(In millions)
Backlog:
Funded	$	3,436	$	2,685	$	2,815
Unfunded	3,687		4,161		3,098
Priced options	12,198		9,174		7,679
Total backlog	$	19,321	$	16,020	$	13,592

Our total backlog consists of remaining performance obligations, certain orders under contracts for which the period of performance has expired, and unexercised option period and other unexercised optional orders. As of March 31, 2019, the Company has $5.8 billion of remaining performance obligations and we expect to recognize more than half of the remaining performance obligations as revenue over the next 12 months, and approximately three quarters over the next 24 months. The remainder is expected to be recognized thereafter. However, given the uncertainties discussed below, as well as the risks described in "Item 1A. Risk Factors", we can give no assurance that we will be able to convert our backlog into revenue in any particular period, if at all. Our backlog includes orders under contracts that in some cases extend for several years. The U.S. Congress generally appropriates funds for our clients on a yearly basis, even though their contracts with us may call for performance that is expected to take a number of years to complete. As a result, contracts typically are only partially funded at any point during their term and all or some of the work to be performed under the contracts may remain unfunded unless and until the U.S. Congress makes subsequent appropriations and the procuring agency allocates funding to the contract.

We view growth in total backlog and consulting staff headcount as the two key measures of our potential business growth. Growing and deploying consulting staff is the primary means by which we are able to achieve profitable revenue growth. To the extent that we are able to hire additional consulting staff and deploy them against funded backlog, we generally recognize increased revenue. Total backlog increased by 20.6% from March 31, 2018 to March 31, 2019 and increased by 17.9% from March 31, 2017 to March 31, 2018. Additions to funded backlog, during fiscal 2019 and 2018 totaled $7.4 billion and $6.0 billion, respectively, with the increase from fiscal 2018 to fiscal 2019 due to the conversion of unfunded backlog to funded backlog, the award of new contracts and task orders under which funding was appropriated, and the subsequent funding of priced options. We report internally on our backlog on a monthly basis and review backlog upon occurrence of certain events to determine if any adjustments are necessary.

We cannot predict with any certainty the portion of our backlog that we expect to recognize as revenue in any future period and we cannot guarantee that we will recognize any revenue from our backlog. The primary risks that could affect our ability to recognize such revenue on a timely basis or at all are: program schedule changes, contract modifications, and our ability to assimilate and deploy new consulting staff against funded backlog; cost-cutting initiatives and other efforts to reduce U.S. government spending, which could reduce or delay funding for orders for services; and delayed funding of our contracts due to delays in the completion of the U.S. government's budgeting process and the use of continuing resolutions by the U.S. government to fund its operations. The amount of our funded backlog is also subject to change, due to, among other factors: changes in congressional appropriations that reflect changes in U.S. government policies or priorities resulting from various military, political, economic or international developments; changes in the use of U.S. government contracting vehicles, and the provisions therein used to procure our services and adjustments to the scope of services, or cancellation of contracts, by the U.S. government at any time. In our recent experience, none of the following additional risks have had a material negative effect on our ability to realize revenue from our funded backlog: the unilateral right of the U.S. government to cancel multi-year contracts and related orders or to terminate existing contracts for convenience or default; in the case of unfunded backlog, the potential that funding will not be made available; and, in the case of priced options, the risk that our clients will not exercise their options.

In addition, contract backlog includes orders under contracts for which the period of performance has expired, and we may not recognize revenue on the funded backlog that includes such orders due to, among other reasons, the tardy submission of invoices by our subcontractors and the expiration of the relevant appropriated funding in accordance with a predetermined expiration date such as the end of the U.S. government's fiscal year. The revenue value of orders included in contract backlog that has not been recognized as revenue due to period of performance expirations has not exceeded approximately 4.6% of funded backlog as of the end of any of the four fiscal quarters preceding the fiscal quarter ended March 31, 2019.

52

We expect to recognize revenue from a substantial portion of funded backlog as of March 31, 2019 within the next twelve months. However, given the uncertainties discussed above, as well as the risks described in "Item 1A. Risk Factors", we can give no assurance that we will be able to convert our backlog into revenue in any particular period, if at all.

Operating Costs and Expenses

Costs associated with compensation and related expenses for our people are the most significant component of our operating costs and expenses. The principal factors that affect our costs are additional people as we grow our business and are awarded new contracts, task orders, and additional work under our existing contracts, and the hiring of people with specific skill sets and security clearances as required by our additional work.

Our most significant operating costs and expenses are described below.

• Cost of Revenue. Cost of revenue includes direct labor, related employee benefits, and overhead. Overhead consists of indirect costs, including indirect labor relating to infrastructure, management and administration, and other expenses.

• Billable Expenses. Billable expenses include direct subcontractor expenses, travel expenses, and other expenses incurred to perform on contracts.

• General and Administrative Expenses. General and administrative expenses include indirect labor of executive management and corporate administrative functions, marketing and bid and proposal costs, and other discretionary spending.

• Depreciation and Amortization. Depreciation and amortization includes the depreciation of computers, leasehold improvements, furniture and other equipment, and the amortization of internally developed software, as well as third-party software that we use internally, and of identifiable long-lived intangible assets over their estimated useful lives.

Seasonality

The U.S. government's fiscal year ends on September 30 of each year. While not certain, it is not uncommon for U.S. government agencies to award extra tasks or complete other contract actions in the weeks before the end of its fiscal year in order to avoid the loss of unexpended fiscal year funds. In addition, we also have historically experienced higher bid and proposal costs in the months leading up to the U.S. government's fiscal year end as we pursue new contract opportunities being awarded shortly after the U.S. government fiscal year end as new opportunities are expected to have funding appropriated in the U.S. government's subsequent fiscal year. We may continue to experience this seasonality in future periods, and our future periods may be affected by it. While not certain, changes in the government's funding and spending patterns have altered historical seasonality trends, supporting our approach to managing the business on an annual basis.

Seasonality is just one of a number of factors, many of which are outside of our control, which may affect our results in any period. See "Item 1A. Risk Factors."

Critical Accounting Estimates and Policies

Our 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 GAAP. The preparation of these consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the consolidated financial statements as well as the reported amounts of revenue and expenses during the reporting period. Management evaluates these estimates and assumptions on an ongoing basis. Our estimates and assumptions have been prepared on the basis of the most current reasonably available information. Actual results may differ from these estimates under different assumptions or conditions.

Our significant accounting policies, including the critical policies and practices listed below, are more fully described and discussed in the notes to the consolidated financial statements. We consider the following accounting policies to be critical to an understanding of our financial condition and results of operations because these policies require the most difficult, subjective or complex judgments on the part of our management in their application, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

Revenue Recognition and Cost Estimation

Our revenues from contracts with customers (clients) are derived from offerings that include consulting, analytics, digital solutions, engineering, and cyber services, substantially with the U.S. government and its agencies, and to a lesser extent, subcontractors. We also serve foreign governments, as well as domestic and international commercial clients. We perform under various types of contracts, which include cost-reimbursable-plus-fee contracts, time-and-material contracts, and fixed-price contracts.

53

We consider a contract with a customer to exist under Topic 606 when there is approval and commitment from us and the customer, the rights of the parties and payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. We will also consider whether two or more contracts entered into with the same customer should be combined and accounted for as a single contract. Furthermore, in certain transactions with commercial clients and with the U.S. government, we may commence providing services prior to receiving a formal approval from the customer. In these situations, we will consider the factors noted above, the risks associated with commencing the work, and legal enforceability in determining whether a contract with the customer exists under Topic 606.

Customer contracts are often modified to change the scope, price, specifications or other terms within the existing arrangement. Contract modifications are evaluated by management to determine whether the modification should be accounted for as part of the original performance obligation(s) or as a separate contract. If the modification adds distinct goods or services and increases the contract value proportionate to the stand-alone selling price of the additional goods or services, it will be accounted for as a separate contract. Generally, our contract modifications do not include goods or services which are distinct, and therefore are accounted for as part of the original performance obligation(s) with any impact on transaction price or estimated costs at completion being recorded as through a cumulative catch-up adjustment to revenue.

We evaluate each service deliverable contracted with the customer to determine whether it represents promises to transfer distinct goods or services. Under Topic 606, these are referred to as performance obligations. One or more service deliverables often represent a single performance obligation. This evaluation requires significant judgment and the impact of combining or separating performance obligations may change the time over which revenue from the contract is recognized. Our contracts generally provide a set of integrated or highly interrelated tasks or services and are therefore accounted for as a single performance obligation. However, in cases where we provide more than one distinct good or service within a customer contract, the contract is separated into individual performance obligations which are accounted for discretely.

Contracts with the U.S. government are subject to the Federal Acquisition Regulation ("FAR") and are priced based on estimated or actual costs of providing the goods or services. We derive a majority of our revenue from contracts awarded through a competitive bidding process. Pricing for non-U.S. government agencies and commercial customers is based on discrete negotiations with each customer. Certain of the our contracts contain award fees, incentive fees or other provisions that may increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and may be based upon customer discretion. Management estimates variable consideration as the most likely amount that we expect to achieve based on our assessment of the variable fee provisions within the contract, prior experience with similar contracts or clients, and management’s evaluation of the performance on such contracts. We may perform work under a contract that has not been fully funded if the work has been authorized by the management and the customer to proceed. We evaluate unfunded amounts as variable consideration in estimating the transaction price. We include the estimated variable consideration in our transaction price to the extent that it is probable that a significant reversal of revenue will not occur upon the ultimate settlement of the variable fee provision. In the limited number of situations where our contracts with customers contain more than one performance obligation, we allocate the transaction price of a contract between the performance obligations in the proportion to their respective stand-alone selling prices. We generally estimate the stand-alone selling price of performance obligations based on an expected cost-plus margin approach as allowed under Topic 606. Our U.S. government contracts generally contain FAR provisions that enable the customer to terminate a contract for default or for the convenience of the U.S. government.

We recognize revenue for each performance obligation identified within our customer contracts when, or as, the performance obligation is satisfied by transferring the promised goods or services. Revenue may either be recognized over time, or at a point in time. We generally recognize revenue over time as our contracts typically involve a continuous transfer of control to the customer. A continuous transfer of control under contracts with the U.S. government and its agencies is evidenced by clauses which require us to be paid for costs incurred plus a reasonable margin in the event that the customer unilaterally terminates the contract for convenience. For contracts where we recognize revenue over time, a contract cost-based input method is generally used to measure progress towards satisfaction of the underlying performance obligation(s). Contract costs include direct costs such as materials, labor and subcontract costs, as well as indirect costs identifiable with, or allocable to, a specific contract that are expensed as incurred. We do not incur material incremental costs to acquire or fulfill contracts. Under a contract cost-based input method, revenue is recognized based on the proportion of contract costs incurred to the total estimated costs expected to be incurred upon completion of the underlying performance obligation. We include generally both funded and unfunded portions of customer contracts in this estimation process.

For interim financial reporting periods, contract revenue attributable to indirect costs is recognized based upon agreed-upon annual forward-pricing rates established with the U.S. government at the start of each fiscal year. Forward pricing rates are estimated and agreed upon between us and the U.S. government and represent indirect contract costs required to execute and administer contract obligations. The impact of any agreed-upon changes, or changes in the estimated annual forward-pricing rates, will be recorded in the interim financial reporting period when such changes are identified. This change relates to the interim financial reporting period differences between the actual indirect cost incurred and allocated to customer contracts

54

compared to the estimated amounts allocated to contracts using the estimated annual forward-pricing rates established with the U.S. government.

On certain contracts, principally time-and-materials and cost-reimbursable-plus-fee contracts, revenue is recognized using the right-to-invoice practical expedient as we are contractually able to invoice the customer based on the control transferred. However, we did not elect to use the practical expedient which would allow us to exclude contracts recognized using the right-to-invoice practical expedient from the remaining performance obligations disclosed below. Additionally, for stand-ready performance obligations to provide services under fixed-price contracts, revenue is recognized over time using a straight-line measure of progress as the control of the services is provided to the customer ratably over the term of the contract. If a contract does not meet the criteria for recognition of revenue over time, we recognize revenue at the point in time when control of the good or service is transferred to the customer. Determining a measure of progress towards the satisfaction of performance obligations requires management to make judgments that may affect the timing of revenue recognition.

Many of our contracts recognize revenue under a contract cost-based input method and require an Estimate-at-Completion (EAC) process, which management uses to review and monitor the progress towards the completion of our performance obligations. Under this process, management considers various inputs and assumptions related to the EAC, including, but not limited to, progress towards completion, labor costs and productivity, material and subcontractor costs, and identified risks. Estimating the total cost at completion of performance obligations is subjective and requires management to make assumptions about future activity and cost drivers under the contract. Changes in these estimates can occur for a variety of reasons and, if significant, may impact the profitability of the our contracts. Changes in estimates related to contracts accounted for under the EAC process are recognized in the period when such changes are made on a cumulative catch-up basis. If the estimate of contract profitability indicates an anticipated loss on a contract, we recognize the total loss at the time it is identified. For fiscal years ended March 31, 2019, 2018 and 2017, the aggregate impact of adjustments in contract estimates was not material.

Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations do not include negotiated but unexercised options or the unfunded value of expired contracts.

Business Combinations

The accounting for the Company's business combinations consists of allocating the purchase price to tangible and intangible assets acquired and liabilities assumed based on their fair values, with the excess recorded as goodwill. Certain fair value measurements include inputs that are unobservable, requiring management to make judgments and estimates that can be affected by contract performance and other factors that may cause final amounts to differ materially from original estimates. We have up to one year from the acquisition date to use additional information obtained to adjust the fair value of the acquired assets and liabilities which may result in changes to the recorded values with an offsetting adjustment to goodwill.

Goodwill and Intangible Assets Impairment

We test goodwill and trade name for impairment at least annually as of January 1 of each year and more frequently if interim indicators of impairment exist. We perform our impairment testing of goodwill at the reporting level. As our business is highly integrated and all of our components have similar economic characteristics, we conclude that we have one reporting unit at the consolidated entity level, which is the same as our single operating segment. We test goodwill for impairment using the quantitative method (primarily based on market capitalization). We test the trade name for impairment using the relief from royalty method that requires management to make significant amount of judgments and estimates in the valuation. We do not consider goodwill, trade name, or any other amortizable intangible assets at risk of impairment.

Amortizable intangible assets are tested for impairment when an event occurs or circumstances change indicating that the carrying amount of the asset may not be recoverable. A significant amount of management judgment is required to determine if an event representing an impairment indicator has occurred during the year, including but not limited to: a decline in forecasted cash flows; a sustained, material decline in the stock price and market capitalization; a significant adverse change in the business climate or economy; or unanticipated competition. An adverse change in any of these factors could have a significant impact on the recoverability of other intangible assets.

During the fiscal year ended March 31, 2017, the Company recorded impairment charges related to intangible assets acquired in an acquisition. During the fiscal years ended March 31, 2019 and 2018, the Company did not record any impairment of intangible assets.

Share-Based Payments

We use the Black-Scholes option-pricing model to estimate the fair value for stock options. Critical inputs into the Black-Scholes option-pricing model include the following: option exercise price, fair value of the stock price, expected life of the option, annualized volatility of the stock, annual rate of quarterly dividends on the stock, and the risk-free interest rate.

During fiscal 2019, the Company’s Board of Directors authorized and declared recurring cash dividends in the amount of $0.19 per share (declared in the first three quarters) and $0.23 per share (declared in the fourth quarter) to holders of Booz Allen Holding’s Class A Common Stock. Therefore, an annualized dividend yield between 1.66% and 2.46% was used in the Black-Scholes option-pricing model for all grants made during the fiscal year. Implied volatility is calculated as of each grant date based on our historical volatility. Other than the expected life of the option, volatility is the most sensitive input to our option grants. The expected term is estimated using historical exercise patterns of our equity award recipients.

The risk-free interest rate used in the Black-Scholes option-pricing model is determined by referencing the U.S. Treasury yield curve rates with the remaining term equal to the expected life assumed at the date of grant.

Forfeitures for our stock option awards are estimated based on our historical analysis of attrition levels and updated annually. We do not expect this assumption to change materially, as attrition levels associated with new option grants have not materially changed.

As a public company, we use the closing price of our Class A Common Stock on the grant date for valuation purposes.

Accounting for Income Taxes

Provisions for federal, state, and foreign income taxes are calculated from the income reported on our consolidated financial statements based on current tax law and also include the cumulative effect of any changes in tax rates from those previously used in determining deferred tax assets and liabilities. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for purposes of preparing consolidated financial statements than for income tax purposes.

Significant judgment is required in determining income tax provisions and evaluating tax positions. We establish reserves for uncertain tax positions when, despite the belief that our tax positions are supportable, there remains uncertainty in a tax position taken in our previously filed income tax returns. For tax positions where it is more likely than not that a tax benefit will be sustained, we record the largest amount of tax benefit with a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. To the extent we prevail in matters for which accruals have been established or are required to pay amounts in excess of reserves, our effective tax rate in a given consolidated financial statement period may be materially impacted.

The 2017 Tax Act was enacted on December 22, 2017 and was generally effective beginning January 1, 2018. We were impacted in several ways as a result of the Tax Act including, but not limited to, provisions which include a reduction in the U.S. federal corporate income tax rate from 35% to 21%, the re-measurement of deferred tax assets and liabilities that was required as a result of the tax rate change and the application of a mandatory one time "transition tax" on unremitted earnings of certain foreign subsidiaries. During fiscal 2019 we completed our assessment for the income tax effects of the 2017 Tax Act, including a true up to all provisional amounts previously recorded, pursuant to SEC staff issues Staff Accounting Bulletin No. 118 ("SAB 118"). The final adjusted amount recorded related to the remeasurement of the deferred tax balances through the third quarter of fiscal 2019 was a decrease in the provision for income taxes of $27.9 million.

NM - Not meaningful

Fiscal 2019 Compared to Fiscal 2018

Revenue

Revenue increased to $6,704.0 million from $6,167.6 million, or an 8.7% increase, primarily due to continued strength in client demand, which led to increased client staff headcount, and an increase in client staff labor, as well as improved contract performance. Revenue growth was also driven by an increase in billable expenses, including subcontractors and direct expenses on behalf of our clients.

57

Cost of Revenue

Cost of revenue increased to $3,100.5 million from $2,866.3 million, or an 8.2% increase. This increase was primarily due to an increase in salaries and salary-related benefits of $176.2 million, higher incentive compensation of $24.6 million, and an increase in employer retirement plan contributions of $7.2 million. The increase in salaries and salary-related benefits was driven by an increase in headcount growth and annual base salary increases. Cost of revenue as a percentage of revenue was 46.2% and 46.5% in fiscal 2019 and fiscal 2018, respectively.

Billable Expenses

Billable expenses increased to $2,004.7 million from $1,861.3 million, or a 7.7% increase. The overall increase was primarily attributable to an increase in use of subcontractors in fiscal 2019 driven by client demand. In addition, contracts which require the Company to incur direct and travel expenses on behalf of clients increased over the prior year. Billable expenses as a percentage of revenue were 29.9% and 30.2% for fiscal 2019 and fiscal 2018, respectively.

General and Administrative Expenses

General and administrative expenses increased to $927.9 million from $855.5 million, or an 8.5% increase. The increase was primarily due to salaries and salary-related benefits of $32.0 million, driven by headcount growth as well as annual base salary increases. Incentive and stock compensation increased $14.6 million and other business expenses and professional fees increased $23.6 million. General and administrative expenses as a percentage of revenue were 13.8% and 13.9% for fiscal 2019 and fiscal 2018, respectively.

Depreciation and Amortization Expense

Depreciation and amortization expense increased to $68.6 million from $64.8 million, or a 5.9% increase, primarily due to increases in depreciation expense resulting from the effects of higher capital expenditures in fiscal 2018.

Interest Expense

Interest expense increased to $89.5 million from $82.3 million, or an 8.8% increase, primarily due to an increase in 1 Month LIBOR, the benchmark interest rate attached to our floating rate debt, which rose approximately 60 basis points throughout fiscal 2019.

Income Tax Expense

Income tax expense decreased to $96.9 million from $128.3 million, or a 24.5% decrease. The effective tax rate decreased to 18.8% in fiscal 2019 from 29.8% in fiscal 2018 primarily due to the 2017 Tax Act's reduction of the U.S. federal corporate tax rate and the re-measurement of deferred income taxes.

Fiscal 2018 Compared to Fiscal 2017

Revenue

Revenue increased to $6,167.6 million from $5,809.5 million, or a 6.2% increase, primarily due to increased client demand which led to increased client staff headcount, and an increase in client staff labor, as well as increases in billable expenses.

Cost of Revenue

Cost of revenue increased to $2,866.3 million from $2,678.7 million, or a 7.0% increase. This increase was primarily due to an increase in salaries and salary-related benefits of $168.8 million, higher incentive compensation of $9.6 million, and an increase in employer retirement plan contributions of $9.5 million. The increase in salaries and salary-related benefits was driven by an increase in headcount growth and annual base salary increases. Cost of revenue as a percentage of revenue was 46.5% and 46.1% in fiscal 2018 and fiscal 2017, respectively.

Billable Expenses

Billable expenses increased to $1,861.3 million from $1,751.1 million, or a 6.3% increase. The overall increase was primarily attributable to an increase in use of subcontractors in fiscal 2019 driven by client demand. In addition, contracts which require the Company to incur travel expenses on behalf of our clients increased over the prior year. Billable expenses as a percentage of revenue were 30.2% and 30.1% in fiscal 2018 and fiscal 2017, respectively.

General and Administrative Expenses

General and administrative expenses increased to $855.5 million from $814.1 million, or a 5.1% increase. The increase was primarily due to salaries and salary-related benefits of $43.0 million, driven by headcount growth as well as annual base salary increases, and occupancy costs of $5.1 million, partially offset by lower incentive compensation of $9.9 million. General and administrative expenses as a percentage of revenue were 13.9% and 14.0% for fiscal 2018 and fiscal 2017, respectively.

58

Depreciation and Amortization Expense

Depreciation and amortization expense increased to $64.8 million from $59.5 million, or an 8.8% increase, primarily due to increases in intangible asset amortization related to the Company's acquisition of Aquilent in fiscal 2017, partially offset by a decrease in amortization of other amortizable intangible assets that fully amortized in fiscal 2017.

Interest Expense

Interest expense increased to $82.3 million from $62.3 million, or a 32.1% increase, primarily as a result of interest expense related to the issuance of the Senior Notes in April 2017.

Income Tax Expense

Income tax expense decreased to $128.3 million from $164.8 million, or a 22.1% decrease. The effective tax rate decreased to 29.8% in fiscal 2018 from 38.7% in fiscal 2017, primarily due to the blended tax rate benefit of the 2017 Tax Act and provisional estimates for the re-measurement of the existing deferred tax balances. The effective tax rate also decreased with the recognition of excess tax benefits of $14.5 million being reflected in earnings as a reduction to income tax expense for fiscal 2018. This was driven by the Company's initial adoption of new accounting guidance in the first quarter of fiscal 2018 whereby excess tax benefits on employee share-based payment awards are now recognized in earnings as a reduction to income tax expense instead of as an adjustment to additional paid-in-capital, as was the case historically.

Liquidity and Capital Resources

As of March 31, 2019, our total liquidity was $1.2 billion, consisting of $284.0 million of cash and cash equivalents, $499.0 million available under the Revolving Credit Facility, and $400.0 million available under the Delayed Draw Facility (which was fully drawn on April 23, 2019). In the opinion of management, we will be able to meet our liquidity and cash needs through a combination of cash flows from operating activities, available cash balances, and available borrowing under the Revolving Credit Facility and Delayed Draw Facility. If these resources need to be augmented, additional cash requirements would likely be financed through the issuance of debt or equity securities.

The following table presents selected financial information for the periods presented:

	Fiscal Year Ended March 31,
	2019			2018			2017
	(In thousands)
Cash and cash equivalents	$	283,990		$	286,958		$	217,417
Total debt	$	1,759,761		$	1,818,579		$	1,663,324
Net cash provided by operating activities	$	499,610		$	369,143		$	382,277
Net cash used in investing activities	(89,212		)	(96,453		)	(300,896		)
Net cash used in financing activities	(413,366		)	(203,149		)	(51,493		)
Total increase (decrease) in cash and cash equivalents	$	(2,968	)	$	69,541		$	29,888

From time to time we evaluate alternative uses for excess cash resources once our operating cash flow and required debt servicing needs have been met. Some of the possible uses of our remaining excess cash at any point in time may include funding strategic acquisitions, further investment in our business, and returning value to shareholders through share repurchases, quarterly dividends, and special dividends. While the timing and financial magnitude of these possible actions are currently indeterminable, the Company expects to be able to manage and adjust its capital structure in the future to meet its liquidity needs.

Historically, we have been able to generate sufficient cash to fund our operations, mandatory debt and interest payments, capital expenditures, and discretionary funding needs. However, due to fluctuations in cash flows, including as a result of the trends and developments described above under "—Factors and Trends Affecting Our Results of Operations" relating to U.S. government shutdowns, U.S. government cost-cutting, reductions or delays in the U.S. government appropriations and spending process and other budgetary matters, it may be necessary from time-to-time in the future to borrow under our Secured Credit Facility to meet cash demands. While the timing and financial magnitude of these possible actions are currently indeterminable, we expect to be able to manage and adjust our capital structure to meet our liquidity needs. Our expected liquidity and capital structure may also be impacted by discretionary investments and acquisitions that we could pursue. We anticipate that cash provided by operating activities, existing cash and cash equivalents, and borrowing capacity under our Revolving Credit Facility will be sufficient to meet our anticipated cash requirements for the next twelve months, which primarily include:

• operating expenses, including salaries;

59

• working capital requirements to fund the growth of our business;

• capital expenditures which primarily relate to the purchase of computers, business systems, furniture and leasehold improvements to support our operations;

• the design, build-out, testing, and potential implementation and operation of new financial management systems;

• commitments and other discretionary investments;

• debt service requirements for borrowings under our Secured Credit Facility and interest payments for the Senior Notes; and

• cash taxes to be paid.

Our ability to fund our operating needs depends, in part, on our ability to continue to generate positive cash flows from operations or, if necessary, raise cash in the capital markets.

Cash Flows

Cash received from clients, either from the payment of invoices for work performed or for advances in excess of costs incurred, is our primary source of cash. We generally do not begin work on contracts until funding is appropriated by the client. Billing timetables and payment terms on our contracts vary based on a number of factors, including whether the contract type is cost-reimbursable, time-and-materials, or fixed-price. We generally bill and collect cash more frequently under cost-reimbursable and time-and-materials contracts, as we are authorized to bill as the costs are incurred or work is performed. In contrast, we may be limited to bill certain fixed-price contracts only when specified milestones, including deliveries, are achieved. In addition, a number of our contracts may provide for performance-based payments, which allow us to bill and collect cash prior to completing the work.

Accounts receivable is the principal component of our working capital and is generally driven by revenue growth with other short-term fluctuations related to the payment practices of our clients. Our accounts receivable reflects amounts billed to our clients as of each balance sheet date. Our clients generally pay our invoices within 30 days of the invoice date, although we experience a longer billing and collection cycle with our global commercial customers. At any month-end, we also include in accounts receivable the revenue that was recognized in the preceding month, which is generally billed early in the following month. Finally, we include in accounts receivable amounts related to revenue accrued in excess of amounts billed, primarily on our fixed-price and cost-reimbursable-plus-award-fee contracts. The total amount of our accounts receivable can vary significantly over time, but is generally sensitive to revenue levels and customer mix. Total accounts receivable (billed and unbilled combined, net of allowance for doubtful accounts) days sales outstanding, or DSO, which we calculate by dividing total accounts receivable by revenue per day during the relevant fiscal quarter, was 70 as of March 31, 2019 and 66 as of March 31, 2018. DSO increased primarily due to delays in the billing and collection of our revenue.

Operating Cash Flow

Net cash provided by operations is primarily affected by the overall profitability of our contracts, our ability to invoice and collect cash from clients in a timely manner, our ability to manage our vendor payments, and the timing of cash paid for income taxes. Continued uncertainty in global economic conditions may also affect our business as customers and suppliers may decide to downsize, defer, or cancel contracts, which could negatively affect the operating cash flows. Net cash provided by operations was $499.6 million in fiscal 2019 compared to $369.1 million in fiscal 2018, or a 35.3% increase. The improvement in operating cash flow over the prior year was primarily due to revenue growth and lower cash paid for taxes in fiscal 2019 as compared to fiscal 2018.

Investing Cash Flow

Net cash used in investing activities was $89.2 million in fiscal 2019 compared to $96.5 million in the prior year, or a 7.5%decrease. The decrease in net cash used in investing activities was primarily due to cash paid for an acquisition in the prior year, partially offset by an increase in capital expenditures over the prior year primarily related to investments in our facilities and infrastructure, financial management systems and information technology.

Financing Cash Flow

Net cash used in financing activities was $413.4 million in fiscal 2019 compared to $203.1 million in the prior year. The increase in net cash used in financing activities was primarily due to net proceeds of $343.3 million received in fiscal 2018 from the issuance of the Senior Notes. This was partially offset by $130 million in net borrowings on the Revolving Credit Facility in fiscal 2018 as well as a $17.5 milliondecrease in share repurchases in fiscal 2019 as compared to the prior year.

60

Dividends and Share Repurchases

The Company paid $0.80 in dividends per share to shareholders of record in fiscal 2019. On May 28, 2019, the Company announced a regular quarterly cash dividend in the amount of $0.23 per share. The quarterly dividend is payable on June 28, 2019 to stockholders of record on June 14, 2019.

The following table summarizes the cash distributions recognized in the consolidated statement of cash flows:

	Fiscal Year Ended March 31,
	2019		2018		2017
	(In thousands)
Recurring dividends (1)	$	114,234	$	103,411	$	92,925
Dividend equivalents (2)	280		951		2,254
Total distributions	$	114,514	$	104,362	$	95,179

(1) Amounts represent recurring dividends that were declared and paid for during each quarter of fiscal 2019, 2018, and 2017, respectively.

(2) Dividend equivalents are distributions made to option holders equal to the previously declared special dividends.

On December 12, 2011, the Board of Directors approved a $30.0 million share repurchase program, which was further increased by the Board of Directors on (i) January 27, 2015 to $180.0 million, (ii) January 25, 2017 to $410.0 million, (iii) November 2, 2017 to $610.0 million and (iv) May 24, 2018 to $910.0 million. On May 23, 2019, the Board of Directors approved an additional increase to our share repurchase authorization of $400.0 million to $1,310.0 million. During fiscal 2019 and 2018, the Company purchased 5.1 million and 7.2 million shares of the Company’s Class A Common Stock for an aggregate of $239.8 million and $257.6 million, respectively. As of May 23, 2019, taking into effect the increase in the share repurchase authorization, the Company may repurchase up to approximately $658.2 million of additional shares of common stock under its share repurchase program.

Any determination to pursue one or more of the above alternative uses for excess cash is subject to the discretion of our Board of Directors, and will depend upon various factors, including our results of operations, financial condition, liquidity requirements, restrictions that may be imposed by applicable law, our contracts, and our Credit Agreement, as amended, and other factors deemed relevant by our Board of Directors.

Indebtedness

Our debt totaled $1,759.8 million and $1,818.6 million as of March 31, 2019 and 2018, respectively. Our debt bears interest at specified rates and is held by a syndicate of lenders (see Note 12 to our consolidated financial statements).

On July 23, 2018 (the "Amendment Effective Date"), Booz Allen Hamilton Inc. ("Booz Allen Hamilton") and Booz Allen Hamilton Investor Corporation ("Investor"), and certain wholly-owned subsidiaries of Booz Allen Hamilton, entered into the Sixth Amendment (the "Sixth Amendment") to the Credit Agreement (as amended, the "Credit Agreement"), dated as of July 31, 2012 among Booz Allen Hamilton, Investor, certain wholly owned subsidiaries of Booz Allen Hamilton and Bank of America, N.A., as Administrative Agent, Collateral Agent and Issuing Lender and the other lenders and financial institutions from time to time party thereto (as previously amended by the First Amendment to Credit Agreement, dated as of August 16, 2013, the Second Amendment to Credit Agreement, date as of May 7, 2014, the Third Amendment to the Credit Agreement, dated as of July 13, 2016, the Fourth Amendment to the Credit Agreement, dated as of February 6, 2017, and the Fifth Amendment to the Credit Agreement, dated as of March 7, 2018). The Sixth Amendment provides for a new delayed draw (the "Delayed Draw Facility") on the tranche A term loan ("Term Loan A") facility in the amount of up to $400.0 million and extended the maturity of the Term Loan A and the revolving credit facility (the "Revolving Credit Facility") to July 2023. Additionally, the Sixth Amendment reduced the interest rate spread applicable to the Term Loan A and the Revolving Credit Facility from a range of 1.50% to 2.25% to a range of 1.25% to 2.00% based on consolidated net total leverage. The interest rate applicable to the Term Loan B ("Term Loan B" and, together with Term Loan A, the "Term Loans") remained unchanged.

Prior to the Sixth Amendment, approximately $1,079.5 million were outstanding under the Term Loan A. Pursuant to the Sixth Amendment, certain lenders converted their existing Term Loan A loans into a new tranche of Term Loan A loans in an aggregate amount, along with Term Loan A loans advanced by certain new lenders, of approximately $1,479.5 million, $400.0 million of which was available as the Delayed Draw Facility. The Delayed Draw Facility is accessible for nine months from the Amendment Effective Date (the "Delayed Draw Availability Period"). The Company was able to draw on the facility up to two times during the Delayed Draw Availability Period with a minimum of $100.0 million per draw. On April 23, 2019, we drew down the full $400 million of the Delayed Draw Facility. We expect that the proceeds will be used for general corporate purposes and other purposes not prohibited by the Credit Agreement.

61

Prior to the Sixth Amendment, $500.0 million was available under the Revolving Credit Facility. Pursuant to the Sixth Amendment, certain lenders under the Credit Agreement converted their existing revolving commitments into a new tranche of revolving commitments (the "New Revolving Commitments" and the revolving credit loans made thereunder, the "New Revolving Loans") in an aggregate amount, along with the New Revolving Commitments of certain lenders, of $500.0 million.

As of March 31, 2019, the Credit Agreement provided Booz Allen Hamilton with a $1,037.7 million Term Loan A, a $400.0 million Delayed Draw Facility, a $391.1 million Term Loan B, and a $500.0 million in New Revolving Commitments with a sub-limit for letters of credit of $100.0 million. As of March 31, 2019, the maturity date of Term Loan A and the termination date for the Revolving Credit Facility was June 23, 2023 and the maturity date of Term Loan B was June 30, 2023. Booz Allen Hamilton’s obligations and the guarantors’ guarantees under the Credit Agreement are secured by a first priority lien on substantially all of the assets (including capital stock of subsidiaries) of Booz Allen Hamilton, Investor and the subsidiary guarantors, subject to certain exceptions set forth in the Credit Agreement and related documentation. Subject to specified conditions, without the consent of the then-existing lenders (but subject to the receipt of commitments), the Term Loans or Revolving Credit Facility may be expanded (or a new term loan facility or revolving credit facility added to the existing facilities) by up to (i) greater of (x) $627 million and (y) 100% of consolidated EBITDA of Booz Allen Hamilton, as of the end of the most recently ended four quarter period for which financial statements have been delivered pursuant to the Credit Agreement plus (ii) the aggregate principal amount under which pro forma consolidated net secured leverage remains less than or equal to 3.50:1.00.

At Booz Allen Hamilton's option, borrowings under the Secured Credit Facility bear interest based either on LIBOR (adjusted for maximum reserves, and subject to a floor of zero) for the applicable interest period or, a base rate equal to the highest of (x) the administrative agent’s prime corporate rate, (y) the overnight federal funds rate plus 0.50% and (z) three-month LIBOR (adjusted for maximum reserves, and subject to a floor of zero) plus 1.00%), in each case plus an applicable margin, payable at the end of the applicable interest period and in any event at least quarterly. The applicable margin for Term Loan A and borrowings under the Revolving Credit Facility ranges from 1.25% to 2.00% for LIBOR loans and 0.25% to 1.00% for base rate loans, in each case based on Booz Allen Hamilton’s consolidated total net leverage ratio. The applicable margin for Term Loan B is 2.00% for LIBOR loans and 1.00% for base rate loans. Unused commitments under the Revolving Credit Facility were from the effective date of the Sixth Amendment until the delivery of financial statements for the first full fiscal quarter ending after the Sixth Amendment effective date pursuant to the Credit Agreement subject to a quarterly fee of 0.25% and are, following such delivery of financial statements, subject to a quarterly fee ranging from 0.20% to 0.35% based on Booz Allen Hamilton’s consolidated total net leverage ratio. Until the Delayed Draw Facility was drawn down on April 23, 2019, commitments under the Delayed Draw Facility were subject to a quarterly fee ranging from 0.20% to 0.35% based on Booz Allen Hamilton's consolidated total net leverage ratio.

Booz Allen Hamilton occasionally borrows under the Revolving Credit Facility in anticipation of cash demands. During fiscal 2019 and 2018, Booz Allen Hamilton accessed a total of $110.0 million and $125.0 million, respectively of its $500.0 million Revolving Credit Facility. As of March 31, 2019 and 2018, there was no outstanding balance on the Revolving Credit Facility.

The Credit Agreement requires quarterly principal payments of 1.25% of the stated principal amount of Term Loan A until maturity, and quarterly principal payments of 0.25% of the stated principal amount of Term Loan B until maturity.

Booz Allen Hamilton also has agreed to pay customary letter of credit and agency fees. As of March 31, 2019 and 2018, Booz Allen Hamilton were contingently liable under open standby letters of credit and bank guarantees issued by its banks in favor of third parties that totaled $9.5 million and $6.3 million, respectively. These letters of credit and bank guarantees primarily support insurance and bid and performance obligations. At March 31, 2019 and 2018, approximately $1.0 million and $1.4 million of these instruments reduce our available borrowings under the Revolving Credit Facility. The remainder is guaranteed under a separate $15.0 million facility established in fiscal 2015, of which $6.5 million and $10.1 million, respectively, was available to us at March 31, 2019 and 2018. As of March 31, 2019, we had $499.0 million of capacity available for additional borrowings under the Revolving Credit Facility.

The Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants include limitations on the following, in each case subject to certain exceptions: (i) indebtedness and liens; (ii) mergers, consolidations or amalgamations, liquidations, wind-ups or dissolutions, and disposition of all or substantially all assets; (iii) dispositions of property; (iv) restricted payments; (v) investments; (vi) transactions with affiliates; (vii) change in fiscal periods; (viii) negative pledges; (ix) restrictive agreements; (x) line of business; and (xi) speculative hedging. The events of default include the following, in each case subject to certain exceptions: (a) failure to make required payments under the Secured Credit Facility; (b) material breaches of representations or warranties under the Secured Credit Facility; (c) failure to observe covenants or agreements under the Secured Credit Facility; (d) failure to pay or default under certain other material indebtedness; (e) bankruptcy or insolvency; (f) certain ERISA events; (g) certain material judgments; (h) actual or asserted invalidity of the Guarantee and Collateral Agreements or the other security documents or failure of the guarantees or perfected liens thereunder; and (i) a change of control. In addition, we are required to meet certain

62

financial covenants at each quarter end, namely Consolidated Net Total Leverage and Consolidated Net Interest Coverage Ratios. As of March 31, 2019, we were compliant with these covenants.

During fiscal 2019, interest payments of $41.9 million and $16.8 million were made for the Term Loan A and Term Loan B facilities, respectively. During fiscal 2018, interest payments of $38.1 million and $14.9 million were made for the Term Loan A and Term Loan B facilities, respectively.

The total outstanding debt balance is recorded in the accompanying consolidated balance sheets net of unamortized discount and debt issuance costs of $19.0 million and $20.7 million as of March 31, 2019 and 2018, respectively.

On April 25, 2017, Booz Allen Hamilton issued $350 million aggregate principal amount of its 5.125% Senior Notes due 2025 under an Indenture, dated April 25, 2017, among Booz Allen Hamilton, certain subsidiaries of Booz Allen Hamilton, as guarantors (the "Subsidiary Guarantors"), and Wilmington Trust, National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, the Subsidiary Guarantors and the Trustee. A portion of the proceeds was used to repay all outstanding loans under the Revolving Credit Facility. During fiscal 2019 and 2018, interest payments of $17.9 million and $9.3 million, respectively, were made for the Senior Notes.

Borrowings under the Term Loans, and, if used, our Revolving Credit Facility, incur interest at a variable rate. In accordance with our risk management strategy between April 6, 2017 and May 24, 2017, Booz Allen Hamilton executed a series of interest rate swaps. As of March 31, 2019, we had interest rate swaps with an aggregate notional amount of $600 million. Between April 2, 2019 and April 4, 2019, Booz Allen Hamilton entered into eight interest rate swap agreements with six different financial institutions to fix the LIBOR portion of the interest rate on outstanding debt under the Credit Agreement, as amended. Each swap has a notional amount of $50 million and fixes LIBOR at rates ranging from 2.259% to 2.308% with an effective date of April 30, 2019 and maturity dates of June 30, 2024 and June 30, 2025. As of April 4, 2019, we had interest rate swaps with an aggregate notional amount of $1.0 billion. These instruments hedge the variability of cash outflows for interest payments on the floating portion of our debt. The Company's objectives in using cash flow hedges are to reduce volatility due to interest rate movements and to add stability to interest expense (see Note 13 in our consolidated financial statements).

Capital Structure and Resources

Our stockholders’ equity amounted to $675.4 million as of March 31, 2019, an increase of $112.9 million compared to stockholders’ equity of $562.5 million as of March 31, 2018. The increase was primarily due to net income of $418.5 million in fiscal 2019, stock-based compensation expense of $31.3 million, and stock option exercises of $12.1 million, partially offset by $250.0 million in treasury stock resulting from the repurchase of shares of our Class A Common Stock and $114.2 million in aggregate quarterly dividend payments in fiscal 2019.

Off-Balance Sheet Arrangements

As of March 31, 2019, we did not have any material off-balance sheet arrangements.

Contractual Obligations

The following table summarizes our contractual obligations that require us to make future cash payments as of March 31, 2019. For contractual obligations, we included payments that we have an unconditional obligation to make.

	Payments Due by Fiscal Periods
	Total		Less Than 1 Year		1 to 3 Years		3 to 5 Years		More Than 5 years
	(In thousands)
Long-term debt (a)	$	1,778,763	$	57,924	$	115,848	$	1,254,991	$	350,000
Operating lease obligations	422,911		70,614		127,213		99,685		125,399

Tax liabilities for uncertain tax positions (c)	11,509		78		10,856		575		—
Total contractual obligations	$	2,654,449	$	293,734	$	400,729	$	1,457,681	$	502,305

(a) See Note 12 to our consolidated financial statements for additional information regarding debt and related matters.

(b) Includes $80 million deferred payment obligation balance plus interest due within the next year.

63

(c) Includes a reserve of $10.2 million for income tax uncertainties created with the acquisition discussed in Note 5 to our consolidated financial statements.

In the normal course of business, we enter into agreements with subcontractors and vendors to provide products and services that we consume in our operations or that are delivered to our clients. These products and services are not considered unconditional obligations until the products and services are actually delivered, at which time we record a liability for our obligation.

Capital Expenditures

Since we do not own any of our facilities, our capital expenditure requirements primarily relate to the purchase of computers, management systems, furniture, and leasehold improvements to support our operations. Direct facility and equipment costs billed to clients are not treated as capital expenses. Our capital expenditures for fiscal 2019 and 2018 were $94.7 million and $78.4 million, respectively. The increase in capital expenditures over the prior year primarily relates to investments in our facilities and infrastructure, financial management systems, and information technology. We expect capital expenditures for fiscal 2020 to increase from fiscal 2019 as a result of continuing investments in these areas.

Commitments and Contingencies

We are subject to a number of reviews, investigations, claims, lawsuits, and other uncertainties related to our business. For a discussion of these items, refer to Note 22 to our consolidated financial statements.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

Market risk is the potential loss arising from adverse changes in market rates and market prices such as those related to interest rates. We actively monitor these exposures and manage such risks through our regular operating and financing activities or through the use of derivative financial instruments.

Our exposure to market risk for changes in interest rates relates primarily to our outstanding debt, cash equivalents, which consist primarily of funds invested in U.S. government money-market funds, our cash flow hedges and our Rabbi trust.

Our exposure to market risk for changes in interest rates related to our outstanding debt will impact our Secured Credit Facility. The interest expense associated with our term loans and any loans under our Revolving Credit Facility will vary with market rates. A hypothetical interest rate increase of 1% would have increased interest expense related to the term facilities under our Secured Credit Facility by approximately $14.8 million in fiscal 2019 and $14.9 million in fiscal 2018, and likewise decreased our income and cash flows. The year over year increase in interest expense is primarily due to an increase in 1 Month LIBOR, the benchmark interest rate attached to our floating rate debt, which rose approximately 60 basis points throughout fiscal 2019, further contributing to the Company’s increased interest expense. This increase in LIBOR was partially offset with a 25 basis point reduction in our Term Loan A and the Revolving Credit Facility credit spreads as part of the Sixth Amendment consummated on July 23, 2018, along with amounts reclassified into interest expense relating to our cash flow hedges.

As of March 31, 2019 and 2018, we had $284.0 million and $287.0 million, respectively, in cash and cash equivalents. The return on our cash and cash equivalents balance as of March 31, 2019 and 2018 was less than 3%. Therefore, the corresponding impact to our interest income, and likewise to our income and cash flow, was not material.

Pursuant to our interest rate risk management strategies, we began using interest rate cash flow hedges in April 2017 to add stability to our incurrence of interest rate expense and to manage our exposure to related interest rate movement. See Note 13 to our consolidated financial statements for further discussion. As of March 31, 2019, we had interest rate swaps with an aggregate notional amount of $600 million, $150 million of which are forward starting with a start date of April 30, 2019. These derivative instruments hedge the variability of cash outflows for interest payments on our variable rate debt and are recorded at fair value on our consolidated balance sheet. As of March 31, 2019, a 25 basis point increase in interest rates would increase the fair value of our interest rate swaps by approximately $1.2 million and a 25 basis point decrease in interest rates would decrease the fair value of our interest rate swaps by approximately $7.1 million.

We established a Rabbi trust to provide for the payment of benefits under our non-qualified deferred compensation plan that became effective in the first quarter of fiscal 2019. As of March 31, 2019, fund assets totaled $3.2 million which include mutual fund investments that are subject to fluctuations in market prices and interest rates. Cash distributions made to plan participants are recognized as operating cash flows in the consolidated statement of cash flows and have the effect of lowering both fund assets and the corresponding fund liabilities on a one-for-one basis. Changes in fair value on fund liabilities offset the changes in fair value of fund assets, and changes in fair value on both fund assets and fund liabilities are recognized in earnings on our consolidated statements of operations. See Notes 15 and 20 to our consolidated financial statements for further discussion.

Booz Allen Hamilton Holding Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Booz Allen Hamilton Holding Corporation (the Company) as of March 31, 2019 and 2018, the related consolidated statements of operations, comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended March 31, 2019, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company at March 31, 2019 and 2018, and the consolidated results of its operations and its cash flows for each of the three years in the period ended March 31, 2019, in conformity with U.S. generally accepted accounting principles.

We also have 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 March 31, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated May 28, 2019 expressed an unqualified opinion thereon.

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.

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

March 31, 2019

1. BUSINESS OVERVIEW

Our Business

Booz Allen Hamilton Holding Corporation, including its wholly owned subsidiaries, or the Company, we, us, and our, was incorporated in Delaware in May 2008. The Company provides management and technology consulting, analytics, engineering, digital solutions, mission operations, and cyber expertise to U.S. and international governments, major corporations, and not-for-profit organizations. The Company reports operating results and financial data in one reportable segment. The Company is headquartered in McLean, Virginia, with approximately 26,100 employees as of March 31, 2019.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP, and the rules and regulations of the U.S. Securities and Exchange Commission, or SEC. All intercompany balances and transactions have been eliminated in consolidation.

The consolidated financial statements and notes of the Company include its subsidiaries, and the joint ventures and partnerships over which the Company has a controlling financial interest. The Company uses the equity method to account for investments in entities that it does not control if it is otherwise able to exert significant influence over the entities' operating and financial policies.

The Company’s fiscal year ends on March 31 and unless otherwise noted, references to fiscal year or fiscal are for fiscal years ended March 31. The accompanying consolidated financial statements present the financial position of the Company as of March 31, 2019 and 2018 and the Company’s results of operations for fiscal 2019, fiscal 2018, and fiscal 2017.

Certain amounts reported in the Company's prior year consolidated financial statements have been reclassified to conform to the current year presentation. Effective April 1, 2018, the Company adopted Accounting Standards Codification (ASC) No. 606, Revenue from Contracts with Customers (Topic 606), and Accounting Standard Updates (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, on a full retrospective method for amounts and percentages presented and disclosures set forth in this Form 10-K for fiscal 2019, 2018, and 2017.

Accounting Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Areas of the consolidated financial statements where estimates may have the most significant effect include contractual and regulatory reserves, valuation and lives of tangible and intangible assets, contingent consideration related to business acquisitions, impairment of long-lived assets, accrued liabilities, revenue recognition, including the accrual of indirect costs, bonus and other incentive compensation, stock-based compensation, reserves for tax benefits and valuation allowances on deferred tax assets, provisions for income taxes, postretirement obligations, certain deferred costs, collectability of receivables, and loss accruals for litigation. Actual results experienced by the Company may differ materially from management's estimates.

Revenue Recognition

The Company's revenues from contracts with customers (clients) are derived from offerings that include consulting, analytics, digital solutions, engineering, and cyber services, substantially with the U.S. government and its agencies, and to a lesser extent, subcontractors. The Company also serves foreign governments, as well as domestic and international commercial clients. The Company performs under various types of contracts, which include cost-reimbursable-plus-fee contracts, time-and-material contracts, and fixed-price contracts.

The Company considers a contract with a customer to exist under Topic 606, when there is approval and commitment from both the Company and the customer, the rights of the parties and payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. The Company also will consider whether two or more contracts entered into with the same customer should be combined and accounted for as a single contract. Furthermore, in certain transactions with commercial clients and with the U.S. government, the Company may commence providing services

F-8

BOOZ ALLEN HAMILTON HOLDING CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

prior to receiving a formal approval from the customer. In these situations, the Company will consider the factors noted above, the risks associated with commencing the work and legal enforceability in determining whether a contract with the customer exists under Topic 606.

Customer contracts are often modified to change the scope, price, specifications or other terms within the existing arrangement. Contract modifications are evaluated by management to determine whether the modification should be accounted for as part of the original performance obligation(s) or as a separate contract. If the modification adds distinct goods or services and increases the contract value proportionate to the stand-alone selling price of the additional goods or services, it will be accounted for as a separate contract. Generally, the Company’s contract modifications do not include goods or services which are distinct, and therefore are accounted for as part of the original performance obligation(s) with any impact on transaction price or estimated costs at completion being recorded as through a cumulative catch-up adjustment to revenue.

The Company evaluates each service deliverable contracted with the customer to determine whether it represents promises to transfer distinct goods or services. Under Topic 606, these are referred to as performance obligations. One or more service deliverables often represent a single performance obligation. This evaluation requires significant judgment and the impact of combining or separating performance obligations may change the time over which revenue from the contract is recognized. The Company’s contracts generally provide a set of integrated or highly interrelated tasks or services and are therefore accounted for as a single performance obligation. However, in cases where we provide more than one distinct good or service within a customer contract, the contract is separated into individual performance obligations which are accounted for discretely.

Contracts with the U.S. government are subject to the Federal Acquisition Regulation ("FAR") and are priced based on estimated or actual costs of providing the goods or services. The Company derives a majority of its revenue from contracts awarded through a competitive bidding process. Pricing for non-U.S. government agencies and commercial customers is based on discrete negotiations with each customer. Certain of the Company’s contracts contain award fees, incentive fees or other provisions that may increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and may be based upon customer discretion. Management estimates variable consideration as the most likely amount that we expect to achieve based on our assessment of the variable fee provisions within the contract, prior experience with similar contracts or clients, and management’s evaluation of the performance on such contracts. The Company may perform work under a contract that has not been fully funded if the work has been authorized by the management and the customer to proceed. The Company evaluates unfunded amounts as variable consideration in estimating the transaction price. We include the estimated variable consideration in our transaction price to the extent that it is probable that a significant reversal of revenue will not occur upon the ultimate settlement of the variable fee provision. In the limited number of situations where our contracts with customers contain more than one performance obligation, the Company allocates the transaction price of a contract between the performance obligations in the proportion to their respective stand-alone selling prices. The Company generally estimates the stand-alone selling price of performance obligations based on an expected cost-plus margin approach as allowed under Topic 606. Our U.S. government contracts generally contain FAR provisions that enable the customer to terminate a contract for default or for the convenience of the U.S. government.

The Company recognizes revenue for each performance obligation identified within our customer contracts when, or as, the performance obligation is satisfied by transferring the promised goods or services. Revenue may either be recognized over time, or at a point in time. The Company generally recognizes revenue over time as our contracts typically involve a continuous transfer of control to the customer. A continuous transfer of control under contracts with the U.S. government and its agencies is evidenced by clauses which require the Company to be paid for costs incurred plus a reasonable margin in the event that the customer unilaterally terminates the contract for convenience. For contracts where the Company recognizes revenue over time, a contract cost-based input method is generally used to measure progress towards satisfaction of the underlying performance obligation(s). Contract costs include direct costs such as materials, labor and subcontract costs, as well as indirect costs identifiable with, or allocable to, a specific contract that are expensed as incurred. The Company does not incur material incremental costs to acquire or fulfill contracts. Under a contract cost-based input method, revenue is recognized based on the proportion of contract costs incurred to the total estimated costs expected to be incurred upon completion of the underlying performance obligation. The Company includes generally both funded and unfunded portions of customer contracts in this estimation process.

For interim financial reporting periods, contract revenue attributable to indirect costs is recognized based upon agreed-upon annual forward-pricing rates established with the U.S. government at the start of each fiscal year. Forward pricing rates are estimated and agreed upon between the Company and the U.S. government and represent indirect contract costs required to

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

execute and administer contract obligations. The impact of any agreed-upon changes, or changes in the estimated annual forward-pricing rates, will be recorded in the interim financial reporting period when such changes are identified. This change relates to the interim financial reporting period differences between the actual indirect cost incurred and allocated to customer contracts compared to the estimated amounts allocated to contracts using the estimated annual forward-pricing rates established with the U.S. government.

On certain contracts, principally time-and-materials and cost-reimbursable-plus-fee contracts, revenue is recognized using the right-to-invoice practical expedient as the Company is contractually able to invoice the customer based on the control transferred. However, we did not elect to use the practical expedient which would allow the Company to exclude contracts recognized using the right-to-invoice practical expedient from the remaining performance obligations disclosed below. Additionally, for stand-ready performance obligations to provide services under fixed-price contracts, revenue is recognized over time using a straight-line measure of progress as the control of the services is provided to the customer ratably over the term of the contract. If a contract does not meet the criteria for recognition of revenue over time, we recognize revenue at the point in time when control of the good or service is transferred to the customer. Determining a measure of progress towards the satisfaction of performance obligations requires management to make judgments that may affect the timing of revenue recognition.

In addition to the right-to-invoice practical expedient discussed above, the Company applied certain other practical expedients permitted by Topic 606, which include: a) using the portfolio approach where contracts with similar characteristics were assessed collectively to evaluate risk of being impacted by the adoption of Topic 606; b) applying the practical expedient allowing the Company to not restate completed contracts which began and ended in the same fiscal year prior to the date of the initial adoption; and c) electing to omit the disclosure related to remaining performance obligations for reporting periods presented before the date of the initial adoption.

Many of our contracts recognize revenue under a contract cost-based input method and require an Estimate-at-Completion (EAC) process, which management uses to review and monitor the progress towards the completion of our performance obligations. Under this process, management considers various inputs and assumptions related to the EAC, including, but not limited to, progress towards completion, labor costs and productivity, material and subcontractor costs, and identified risks. Estimating the total cost at completion of performance obligations is subjective and requires management to make assumptions about future activity and cost drivers under the contract. Changes in these estimates can occur for a variety of reasons and, if significant, may impact the profitability of the Company’s contracts. Changes in estimates related to contracts accounted for under the EAC process are recognized in the period when such changes are made on a cumulative catch-up basis. If the estimate of contract profitability indicates an anticipated loss on a contract, the Company recognizes the total loss at the time it is identified. For fiscal years ended March 31, 2019, 2018 and 2017, the aggregate impact of adjustments in contract estimates was not material.

Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations do not include negotiated but unexercised options or the unfunded value of expired contracts.

Cash and Cash Equivalents

Cash and cash equivalents include operating cash on hand and highly liquid investments having a weighted average maturity of 60 days or less and a weighted average life of 120 days or less. The Company’s cash equivalents consist primarily of government money market funds and money market deposit accounts. The Company maintains its cash and cash equivalents in bank accounts that, at times, exceed the federally insured FDIC limits. The Company has not experienced any losses in such accounts.

Valuation of Accounts Receivable

The Company maintains allowances for doubtful accounts against certain billed and unbilled receivables based upon the latest information regarding whether specific charges are recoverable or invoices are ultimately collectible. Assessing the recoverability of charges and collectability of customer receivables requires management judgment. The Company determines its allowance for doubtful accounts by specifically analyzing individual accounts receivable, historical bad debts, customer credit-worthiness, current economic conditions, accounts receivable aging trends for billed receivables, availability of funding, compliance with contractual terms and conditions, client satisfaction with work performed, and other factors impacting unbilled receivables. Valuation reserves are periodically re-evaluated and adjusted as more information about the ultimate recoverability

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

and collectability of accounts receivable becomes available. Upon determination that a receivable is uncollectible, the receivable balance and any associated reserve are written off.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents and accounts receivable. The Company’s cash equivalents are generally invested in U.S. government money market funds and money market deposit accounts. The Company believes that credit risk for accounts receivable is limited as the receivables are primarily with the U.S. government.

Property and Equipment

Property and equipment are recorded at cost, and the balances are presented net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. Furniture and equipment is depreciated over five to ten years, and computer equipment is depreciated over four years. Leasehold improvements are amortized over the shorter of the useful life of the asset or the lease term. Maintenance and repairs are charged to expense as incurred.

Rent expense is recorded on a straight-line basis over the life of the respective lease. The difference between the cash payment and rent expense is recorded as deferred rent in either accounts payable and other accrued expenses or other long-term liabilities in the consolidated balance sheets, depending on when the amounts will be recognized. The Company receives incentives for tenant improvements on certain of its leases. The cash expended on such improvements is recorded as property and equipment and amortized over the life of the associated asset, or lease term, whichever is shorter. Incentives for tenant improvements are recorded as deferred rent in either accounts payable and other accrued expenses or other long-term liabilities in the consolidated balance sheets depending on when the amounts will be recognized. Incentives for tenant improvements are amortized on a straight-line basis over the lease term

Business Combinations

The accounting for the Company’s 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. The Company has 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.

We have a contingent consideration arrangement in connection with a business acquisition which requires a fair value measurement determined using probability-weighted cash flows. See Note 20 to our consolidated financial statements for further information about the valuation of the contingent consideration liability and the inputs used in the fair value measurement.

Intangible Assets

Intangible assets primarily consist of the Company's trade name, customer relationships, software and other amortizable intangible assets. The Company capitalizes the following costs associated with developing internal-use computer software pertaining to upgrades in our business and financial systems: (i) external direct costs of materials and services consumed in developing or obtaining internal-use computer software and (ii) certain payroll and payroll-related costs for Company employees who are directly associated with the development of internal-use software, to the extent of the time spent directly on the project. Customer relationships are generally amortized on an accelerated basis over the expected life based on projected future cash flows of approximately three to twelve years. Software purchased or developed for internal use is amortized over three to six years. The Company's trade name is not amortized, but is tested for impairment on at least an annual basis as of January 1 and more frequently if interim indicators of impairment exist. The trade name is considered to be impaired if the carrying value exceeds its estimated fair value. The Company used the relief from royalty method to estimate the fair value. The fair value of the asset is the present value of the license fees avoided by owning the asset, or the royalty savings. During the fiscal year ended March 31, 2017, the Company recorded impairment charges related to intangible assets acquired in an acquisition. During the fiscal years ended March 31, 2019 and March 31, 2018, the Company did not record any impairment of intangible assets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

Goodwill

The Company assesses goodwill for impairment on at least an annual basis on January 1 unless interim indicators of impairment exist. Goodwill is considered to be impaired when the net book value of a reporting unit exceeds its estimated fair value. The Company operates as a single operating segment and as a single reporting unit for the purpose of evaluating goodwill. As of January 1, 2019, the Company performed its annual impairment test of goodwill by comparing the fair value of the Company (based on market capitalization) to the carrying value of the Company's net equity, and concluded that the fair value of the reporting unit was significantly greater than the carrying amount. During the fiscal years ended March 31, 2019, 2018, and 2017, the Company did not record any impairment of goodwill.

Long-Lived Assets

The Company reviews its long-lived assets, including property and equipment and amortizable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. If the total of the expected undiscounted future net cash flows is less than the carrying amount of the asset, a loss is recognized for any excess of the carrying amount over the fair value of the asset. During the fiscal years ended March 31, 2019, 2018, and 2017, the Company did not record any material impairment charges.

Income Taxes

The Company provides for income taxes as a “C” corporation on income earned from operations. The Company is subject to federal, state, and foreign taxation in various jurisdictions.

Deferred tax assets and liabilities are recorded to recognize the expected future tax benefits or costs of events that have been, or will be, reported in different years for financial statement purposes than for tax purposes. Deferred tax assets and liabilities are computed based on the difference between the consolidated financial statement carrying amount and tax basis of assets and liabilities using enacted tax rates and laws for the years in which these items are expected to reverse. If management determines that some portion or all of a deferred tax asset is not “more likely than not” to be realized, a valuation allowance is recorded as a component of the income tax provision to reduce the deferred tax asset to an appropriate level in that period. In determining the need for a valuation allowance, management considers all positive and negative evidence, including historical earnings, projected future taxable income, future reversals of existing taxable temporary differences, taxable income in prior carryback periods, and prudent, feasible tax-planning strategies.

The Company periodically assesses its tax positions for all periods open to examination by tax authorities based on the latest available information. Where it is not more likely than not that the Company’s tax position will be sustained, the Company records its best estimate of the resulting tax liability, penalties, and interest in the consolidated financial statements. These uncertain tax positions are recorded as a component of income tax expense. As uncertain tax positions in periods open to examination are closed out, or as new information becomes available, the resulting change is reflected in the recorded liability and income tax expense. Penalties and interest recognized related to the reserves for uncertain tax positions are recorded as a component of income tax expense.

See Note 14 to our consolidated financial statements for further information regarding the effects of U.S. tax law changes enacted during the third fiscal quarter of 2018 and financial reporting guidance issued by the SEC.

Comprehensive Income

Comprehensive income is the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, and is presented in the consolidated statements of comprehensive income. Accumulated other comprehensive loss as of March 31, 2019 and 2018 consisted of net unrealized losses on the Company’s defined and postretirement benefit plans and unrealized gains or losses on interest rate swaps designated as cash flow hedges.

Share-Based Payments

Share-based payments to employees are recognized in the consolidated statements of operations based on their grant date fair values with the expense for time vested awards recognized on an accelerated basis over the vesting period. The expense for performance awards is recognized straight line over the vesting period. The Company uses the Black-Scholes option-pricing model to determine the fair value of its option awards at the time of grant.

Defined Benefit Plan and Other Postretirement Benefits

The Company recognizes the underfunded status of defined benefit plans on the consolidated balance sheets within other long-term liabilities. Gains and losses, and prior service costs and credits that have not yet been recognized through net periodic

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

benefit cost are recognized in accumulated other comprehensive income (loss), net of tax effects, and will be amortized as a component of net periodic cost in future periods. The measurement date, the date at which the benefit obligations are measured, is the Company’s fiscal year-end.

The Company also offers medical and dental benefits to inactive employees (and their eligible dependents) on long-term disability. The Company accrues the costs of the benefits at the date the inactive employee becomes disability eligible and elects to participate in the benefit. The accrued cost for such benefits is calculated using an actuarial estimate of the present value of all future benefit payments for obligations at the end of the fiscal year.

Self-Funded Medical Plans

The Company maintains self-funded medical insurance. Self-funded plans include Consumer Driven Health Plans with a Health Savings Account option and traditional choice plans. Further, self-funded plans also include prescription drug and dental benefits. The Company records an incurred but unreported claim liability in the accrued compensation and benefits line of the consolidated balance sheets for self-funded plans based on an actuarial valuation. The estimate of the incurred but unreported claim liability was provided by a third-party valuation firm, primarily based on claims and participant data for the medical, dental, and pharmacy related costs.

Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, we consider the principal or most advantageous market in which the asset or liability would transact, and if necessary, consider assumptions that market participants would use when pricing the asset or liability.

The accounting guidance for fair value measurements establishes a three-level fair value hierarchy that prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3). Assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. See Note 20 to our consolidated financial statements for additional information on the Company’s fair value measurements.

Recently Adopted Accounting Standards

In March 2019, the SEC issued its Final Rule Release No. 33-10618, FAST Act Modernization and Simplification of Regulation S-K. The guidance in this Release revises certain disclosure requirements in SEC Regulation S-K, with the intent of improving the readability of filed documents and simplifying registrants' compliance efforts. The Company adopted certain aspects of this Release in the fourth quarter of fiscal 2019 which did not have a material impact on the consolidated financial statements. Other aspects not yet adopted are still being evaluated but are not expected to be material.

The Company completed its assessment for the tax effects of the Tax Cuts and Jobs Act, or the 2017 Tax Act, under the guidance of Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, or SAB 118, during the third quarter of fiscal 2019. The Company recorded adjustments to previously recognized provisional estimates primarily related to the re-measurement effects on certain deferred tax balances. The completion of its assessment resulted in a reduction in the provision for income taxes during the third quarter of fiscal 2019. See Note 14 to the consolidated financial statements for further information regarding the impact of the 2017 Tax Act on fiscal 2019.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The amendments set forth certain presentation requirements, including that such analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed with all significant reconciling items described by appropriate captions with contributions from and distributions to owners shown separately. The amendments became effective on November 5, 2018 and did not have a material effect on the Company's consolidated financial statements for fiscal 2019. According to the SEC’s Questions and Answers of General Applicability Question 105.09 dated September 25, 2018 and updated October 4, 2018, the SEC would not object if the filer’s first presentation of the changes in stockholders’ equity is included in its Form 10-Q for the

F-13

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

quarter that begins after the effective date of the amendments. The Company will first present such changes beginning with the first quarter of fiscal 2020.

In August 2018, the FASB issued ASU 2018-14, Compensation -Retirement Benefits -Defined Benefit Plans -General (Topic 715-20) - Disclosure Framework -Changes to the Disclosure Requirement for Defined Benefit Plans. This guidance is designed to improve the effectiveness of disclosures by removing and adding disclosures related to defined benefit plans. ASU 2018-14 is effective for reporting periods beginning after December 15, 2020 with early adoption permitted. In the fourth quarter of fiscal 2019 the Company early adopted this standard and adoption of this standard did not have a material impact on the consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. This guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Additionally, the guidance also expands an entity's ability to apply hedge accounting for nonfinancial and financial risk components, simplifies the hedge documentation and hedge effectiveness assessment requirements, and modifies certain disclosure requirements. ASU 2017-12 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. In the fourth quarter of fiscal 2019 the Company early adopted this standard using the modified retrospective approach. The adoption of this standard did not have a material impact on the consolidated financial statements.

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Codification No. 606, Revenue from Contracts with Customers (Topic 606). Topic 606, as amended, replaced existing revenue recognition standards by outlining a single set of comprehensive principles for recognizing revenue. The revenue standard also significantly expanded the disclosure requirements for revenue arrangements. Amendments to Topic 606 have generally focused on promoting a more consistent interpretation and application of the principles for recognizing revenue.

Topic 606 was effective for the Company beginning on April 1, 2018 (i.e., beginning with the first quarter fiscal 2019 interim financial statements). The Company adopted the new revenue standard using the full retrospective transition method, which requires that it be applied to each prior reporting period presented and that the cumulative effect of applying the standard be recognized at the earliest period presented (i.e., April 1, 2016, the beginning of the first quarter of fiscal 2017). During fiscal 2018, the Company completed its assessment of the cumulative effect of adopting Topic 606 and assessed the impact to be immaterial as of the date of adoption. The cumulative impact on our retained earnings for the earliest period presented of April 1, 2016 was an increase of $2.9 million. Thereafter, the adoption of Topic 606 increased our fiscal 2017 retained earnings by $8.4 million and decreased our fiscal 2018 retained earnings by $3.4 million, resulting in a cumulative impact on our retained earnings of$7.9 million as of April 1, 2018. The impact of Topic 606 on fiscal 2017 and 2018 results may not be representative of the impact on subsequent years’ results.

The Company also retrospectively adopted ASU 2017-07, which changed the presentation of net periodic benefit cost components on the condensed consolidated statement of operations. Under this guidance, the service cost component of net periodic benefit cost continues to be presented consistent with other employee compensation costs and within operating income, while the remaining components of net periodic benefit costs are excluded from operating income. As a result, net periodic benefit costs related to non-service components were reclassified to Other income (expense), net in the consolidated statement of operations for fiscal 2018 and 2017. See adoption impacts of ASU 2017-07 in the table below.

The Company's previously issued consolidated financial statements have been adjusted for the retrospective adoption of both Topic 606 and ASU 2017-07, as summarized in the following table:

Recent Accounting Pronouncements Not Yet Adopted

In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This guidance requires a customer in a cloud computing arrangement that is a service contract to follow existing internal-use software guidance to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 generally aligns the guidance on capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with that of implementation costs incurred to develop or obtain internal-use software, including hosting arrangements that include an internal-use software license. ASU 2018-15 is effective for interim reporting periods for fiscal years beginning after December 15, 2019. Early adoption is permitted. The standard may be adopted either retrospectively or prospectively. The Company is currently assessing the future impact of this update on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability of accounting for lease transactions. The new leasing standard requires lessees to recognize lease assets and lease liabilities on their balance sheet for all leases with a lease term of greater than 12 months. Lessor accounting is largely unchanged. Topic 842 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB provided an alternative transition method of adoption through ASU No. 2018-11, Targeted Improvements, which permits the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption. The Company will adopt the standard beginning in fiscal 2020 using the modified retrospective transition approach, specifically, using the alternative transition method provided by ASU 2018-11.

A dedicated implementation team has substantially completed its evaluation of the impact of the new standard. The Company's assessment efforts to date have included reviewing the provisions of Topic 842, gathering information to evaluate its lease population and portfolio, evaluating the nature of real and personal property and other arrangements that may meet the definition of a lease, designing and implementing one-time implementation controls as well as new post-adoption lease processes and controls, implementing a new lease accounting software solution, and evaluating certain accounting policy elections. As a result of our evaluation, the Company identified changes to and modified certain of our accounting policies and practices. While some modifications were complex to design and test, the effect of such changes are not expected to be significant upon adoption of Topic 842. The Company will elect certain practical expedients provided under Topic 842, including the option not to apply lease recognition for short–term leases; an election to not separate lease from non-lease components; and a package of practical expedients such that, upon the initial adoption of Topic 842, the Company will not reassess whether expired or existing contracts contain leases, nor will the Company reassess the lease classification for expired or existing leases.

The Company expects that upon adoption it will recognize a material right-of-use asset of approximately $270 million and a lease liability of approximately $330 million on the balance sheet, which is inclusive of required conforming balance sheet reclassifications. The Company does not expect the standard to have any other material impact on the consolidated financial statements or results of operations. Adoption of the standard is not expected to impact the Company’s ability to comply with the financial covenants as defined in the Credit Agreement discussed further in Note 12. The Company is continuing to refine its processes in order to meet the accounting and disclosure requirements upon adoption of Topic 842 in the first quarter of fiscal2020.

Other recent accounting pronouncements issued during fiscal 2019 and through the filing date are not expected to have a material impact on the Company's present or historical consolidated financial statements.

3. REVENUE

The Company's revenues from contracts with customers (clients) are derived from offerings that include consulting, analytics, digital solutions, engineering, and cyber services, substantially with the U.S. government and its agencies, and to a lesser extent, subcontractors. The Company also serves foreign governments, as well as domestic and international commercial clients. The Company performs under various types of contracts, which include cost-reimbursable-plus-fee contracts, time-and-material contracts, and fixed-price contracts.

Disaggregation of Revenue

We disaggregate our revenue from contracts with customers by contract type, customer, as well as whether the Company acts as prime contractor or sub-contractor, as we believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. The following series of tables presents our revenue disaggregated by these categories.

Revenue by Contract Type:

We generate revenue under the following three basic types of contracts:

• Cost-Reimbursable Contracts: Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract, up to a ceiling based on the amount that has been funded, plus a fixed fee or award fee.

• Time-and-Materials Contracts: Under contracts in this category, we are paid a fixed hourly rate for each direct labor hour expended, and we are reimbursed for billable material costs and billable out-of-pocket expenses inclusive of allocable indirect costs. We assume the financial risk on time-and-materials contracts because our costs of performance may exceed negotiated hourly rates.

• Fixed-Price Contracts: Under a fixed-price contract, we agree to perform the specified work for a predetermined price. To the extent our actual direct and allocated indirect costs decrease or increase from the estimates upon which the price was negotiated, we will generate more or less profit, respectively, or could incur a loss.

The table below presents the total revenue for each type of contract:

	Fiscal Year Ended March 31,
	2019			2018			2017
Cost-reimbursable	$	3,580,595	53%	$	3,155,049	51%	$	2,882,178	50%

	2019			2018			2017
Prime Contractor	$	6,159,918	92%	$	5,626,544	91%	$	5,261,499	91%

Total Revenue	$	6,704,037	100%	$	6,167,600	100%	$	5,809,491	100%

Performance Obligations

Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations do not include negotiated but unexercised options or the unfunded value of expired contracts.

As of March 31, 2019, the Company had $5.8 billion of remaining performance obligations and we expect to recognize more than half of the remaining performance obligations as revenue over the next 12 months, and approximately three quarters over the next 24 months. The remainder is expected to be recognized thereafter.

Contract Balances

As discussed in Note 2, the Company's performance obligations are typically satisfied over time and revenue is generally recognized using a cost-based input method. Fixed-price contracts are typically billed to the customer using milestone or fixed monthly payments, while cost-reimbursable-plus-fee and time-and-material contracts are typically billed to the customer at periodic intervals (e.g. monthly or weekly) as indicated by the terms of the contract. Disparities between the timing of revenue recognition and customer billings and cash collections results in net contract assets or liabilities being recognized at the end of each reporting period.

Contract assets primarily consist of unbilled receivables typically resulting from revenue recognized exceeding the amount billed to the customer and right to payment is not just subject to the passage of time. Contract liabilities primarily consist of advance payments, billings in excess of costs incurred and deferred revenue. Contract assets and liabilities are reported on a net contract basis at the end of each reporting period. The Company maintains an allowance for doubtful accounts to provide for an estimate of uncollected receivables. Refer to Note 7 for more information on receivables recognized from contracts accounted for under Topic 606.

The following table summarizes the contract balances recognized on the Company’s consolidated balance sheets:

	March 31, 2019		March 31, 2018
Contract assets:
Current	$	846,372	$	738,646
Long-term	61,391		59,633
Total	907,763		798,279
Contract liabilities:
Advance payments, billings in excess of costs incurred and deferred revenue	$	21,316	$	27,522

Changes in contract assets and contract liabilities are primarily due to the timing difference between the Company’s performance of services and payments from customers. For fiscal 2019, 2018 and 2017, we recognized revenue of $25.3 million, $16.2 million and $10.5 million, respectively, related to our contract liabilities on April 1, 2018, 2017 and 2016, respectively. To determine revenue recognized from contract liabilities during the reporting periods, the Company allocates revenue to individual contract liability balances and applies revenue recognized during the reporting periods first to the beginning balances of contract liabilities until the revenue exceeds the balances.

4. EARNINGS PER SHARE

The Company computes basic and diluted earnings per share amounts based on net income for the periods presented. The Company uses the weighted average number of common shares outstanding during the period to calculate basic earnings per share, or EPS. Diluted EPS adjusts the weighted average number of shares outstanding to include the dilutive effect of outstanding common stock options and other stock-based awards.

The Company currently has outstanding shares of Class A Common Stock. Unvested Class A Restricted Common Stock holders are entitled to participate in non-forfeitable dividends or other distributions. These unvested restricted shares participated in the Company's dividends declared and paid in each quarter of fiscal 2019, 2018, and 2017. As such, EPS is calculated using the two-class method whereby earnings are reduced by distributed earnings as well as any available undistributed earnings allocable to holders of unvested restricted shares. A reconciliation of the income used to compute basic and diluted EPS for the periods presented are as follows:

	Fiscal Year Ended March 31,
	2019		2018		2017
Earnings for basic computations (1)	$	416,664	$	299,824	$	258,495
Weighted-average Class A Common Stock outstanding	141,910,799		145,964,574		148,218,968
Total weighted-average common shares outstanding for basic computations	141,910,799		145,964,574		148,218,968
Earnings for diluted computations (1)	$	416,675	$	299,837	$	258,514
Dilutive stock options and restricted stock	1,245,377		1,785,448		2,055,672

Earnings per common share
Basic	$	2.94	$	2.05	$	1.74
Diluted	$	2.91	$	2.03	$	1.72

(1) During fiscal 2019, 2018, and 2017 approximately 0.6 million, 0.8 million, and 1.3 million shares of participating securities were paid dividends totaling $0.6 million, $0.8 million, and $0.9 million, respectively. For fiscal 2019, there were undistributed earnings of $1.2 million allocated to the participating class of securities in both basic and diluted earnings per share. For fiscal 2018, there were undistributed earnings of $1.1 million allocated to the participating class of securities in both basic and diluted earnings per share. For fiscal 2017, there were undistributed earnings of $1.4 million allocated to the participating class of securities in both basic and diluted earnings per share. The allocated undistributed earnings and the dividends paid comprise the difference between net income presented on the consolidated statements of operations and earnings for basic and diluted computations for fiscal 2019, 2018, and 2017.

The EPS calculation for fiscal 2019, 2018, and 2017 excludes 0.2 million, 0.3 million, and 0.05 million options, respectively, as their impact was anti-dilutive.

5. ACQUISITIONS

There were no material acquisitions or dispositions during fiscal 2019 and 2018 or through the period subsequent to the issuance of the current financial statements.

Fiscal 2017 Acquisition

On January 24, 2017, the Company acquired eGov Holdings, Inc., which we refer to as Aquilent. As a result of the transaction, Aquilent became a wholly owned subsidiary of the Company. Aquilent is an architect of IT solutions for the U.S. Federal government. The acquisition further expands the Company's ability to blend its consulting heritage with advanced technical expertise.

The total purchase consideration paid at closing was $253.6 million. As part of the acquisition, the Company recorded the assets acquired and liabilities assumed at their acquisition date estimated fair value, with the difference between the fair value of the net assets acquired and the acquisition consideration reflected as goodwill. The following table represents the final allocation of fair value of assets acquired and liabilities assumed:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

Current assets	$	15,809
Other tangible assets	1,144
Customer-relationship intangible assets	69,000
Goodwill	199,826
Current liabilities	(8,450		)
Tax liability	(13,554		)
Income tax uncertainty	(10,221		)
Total purchase consideration transfer at closing	$	253,554

The identifiable customer-relationship intangible assets of $69.0 million was valued using the excess earnings method discounted cash flow approach, incorporating Level 3 inputs as described under the fair value hierarchy of ASC 820 and it is being amortized over 12 years. An acquisition date tax of $13.6 million was relieved and paid during the first quarter of fiscal 2018. The Company continues to carry a related reserve of $10.2 million for income tax uncertainties created with the acquisition resulting from uncertainty in the sustainability of Aquilent's prior tax-return positions under examination with the relevant tax authorities. The goodwill of $199.8 million was primarily attributed to the specialized workforce and the expected synergies between the Company and Aquilent. The majority of the goodwill is expected to be deductible for tax purposes. Pro forma results of operations for this acquisition are not presented because it is not material to the Company's consolidated results.

6. GOODWILL AND INTANGIBLE ASSETS

Goodwill

As of March 31, 2019 and 2018, goodwill was $1,581.2 million and $1,581.1 million, respectively.

The Company performed an annual impairment test of the trade name as of January 1, 2019 and 2018, and did not identify any impairment. However, the Company recognized an impairment charge of $3.8 million in fiscal 2017 for acquired technology, customer relationships and other intangible assets associated with a historical business acquisition. During fiscal 2018, gross carrying value and accumulated amortization were reduced related to fully-amortized intangible assets.

11. DEFERRED PAYMENT OBLIGATION

Pursuant to an Agreement and Plan of Merger, or the Merger Agreement, dated as of May 15, 2008, and subsequently amended, The Carlyle Group indirectly acquired all of the issued and outstanding stock of the Company. In connection with this transaction, on July 31, 2008 the Company established a Deferred Payment Obligation, or DPO, of $158.0 million, payable 8.5 years after the Closing Date, or until settlement of all outstanding claims, less any settled claims. Pursuant to the Merger Agreement, $78.0 million of the $158.0 million DPO was required to be paid in full to the selling shareholders. On December 11, 2009, in connection with a recapitalization transaction, $100.4 million was paid to the selling shareholders, of which $78.0 million was the repayment of that portion of the DPO, with approximately $22.4 million representing accrued interest.

The remaining $80.0 million is available to indemnify the Company for certain pre-acquisition tax contingencies, related interest and penalties, and other matters pursuant to the Merger Agreement. Any amounts remaining after the settlement of all claims will be paid out to the selling shareholders. Remaining potential claims outstanding that may be indemnified pursuant to the Merger Agreement relate to former officers and stockholders’ suits that are still in litigation (See Note 22 to our consolidated financial statements).

During fiscal 2019, the Company accrued interest at a rate of 5% per six-month period on the unpaid DPO balance, net of any settled claims or payments, which was $80.0 million as of March 31, 2019 and 2018. Accordingly, $81.3 million was recorded within other current liabilities as of March 31, 2019 and 2018, representing the residual balances estimated to be paid to the selling shareholders subject to any remaining potential claims based on consideration of accrued interest and other matters.

Terms Loans and Revolving Credit Facility

On July 23, 2018 (the "Amendment Effective Date"), Booz Allen Hamilton Inc.("Booz Allen Hamilton") and Booz Allen Hamilton Investor Corporation ("Investor"), and certain wholly-owned subsidiaries of Booz Allen Hamilton, entered into the Sixth Amendment (the "Sixth Amendment") to the Credit Agreement (as amended, the "Credit Agreement"), dated as of July 31, 2012 among Booz Allen Hamilton, Investor, certain wholly owned subsidiaries of Booz Allen Hamilton and Bank of America, N.A., as Administrative Agent, Collateral Agent and Issuing Lender and the other lenders and financial institutions from time to time party thereto (as previously amended by the First Amendment to Credit Agreement, dated as of August 16, 2013, the Second Amendment to Credit Agreement, date as of May 7, 2014, the Third Amendment to the Credit Agreement, dated as of July 13, 2016, the Fourth Amendment to the Credit Agreement, dated as of February 6, 2017 and the Fifth Amendment to the Credit Agreement, dated as of March 7, 2018). The Sixth Amendment provides for a new delayed draw (the "Delayed Draw Facility") on the tranche A term loan ("Term Loan A") facility in the amount of up to $400.0 million and extended the maturity of the Term Loan A and the revolving credit facility (the "Revolving Credit Facility") to July 2023. Additionally, the Sixth Amendment reduced the interest rate spread applicable to Term Loan A and the Revolving Credit Facility from a range of 1.50% to 2.25% to a range of 1.25% to 2.00% based on consolidated net leverage. The interest rate applicable to the Term Loan B ("Term Loan B" and, together with Term Loan A, the "Term Loans") remained unchanged.

Prior to the Sixth Amendment, approximately $1,079.5 million was outstanding under Term Loan A. Pursuant to the Sixth Amendment, certain lenders converted their existing Term Loan A loans into a new tranche of Term Loan A loans in an aggregate amount, along with Term Loan A loans advanced by certain new lenders, of approximately $1,479.5 million, $400.0 million of which will be available as the Delayed Draw Facility. The Delayed Draw Facility is accessible for nine months from the Amendment Effective Date (the "Delayed Draw Availability Period"). The Company is able to draw on the facility up to two times during the Delayed Draw Availability Period in an amount per draw (x) of not less than $100.0 million per draw or (y) equal to the amount of unused commitments in respect of the Delayed Draw Facility remaining at the time of such borrowing. The proceeds from the new lenders were used to prepay in full all of the existing Term Loan A tranche. The proceeds of the Delayed Draw Facility will be used for general corporate purposes and other purposes not prohibited by the Credit Agreement.

Prior to the Sixth Amendment, $500.0 million was available under the revolving credit facility. Pursuant to the Sixth Amendment, certain lenders under the Existing Credit Agreement converted their Existing Revolving Commitments into a new tranche of revolving commitments (the "New Revolving Commitments" and the revolving credit loans made thereunder, the "New Revolving Loans") in an aggregate amount, along with New Revolving Commitments of certain new lenders, of $500.0 million.

As of March 31, 2019, the Credit Agreement provided the Company with a $1,037.7 million Term Loan A, a $400 million Delayed Draw Facility, and a $391.1 million Term Loan B and a $500.0 million revolving credit facility (the “Revolving Credit Facility”) with a sub-limit for letters of credit of $100.0 million. As of March 31, 2019, the maturity date of Term Loan A and the termination date for the Revolving Credit Facility was July 23, 2023 and the maturity date of Term Loan B was June 30, 2023. Booz Allen Hamilton’s obligations and the guarantors’ guarantees under the Credit Agreement are secured by a first priority lien on substantially all of the assets (including capital stock of subsidiaries) of Booz Allen Hamilton, Investor and the subsidiary guarantors, subject to certain exceptions set forth in the Credit Agreement and related documentation. Subject to specified conditions, without the consent of the then-existing lenders (but subject to the receipt of commitments), the Term Loans or Revolving Credit Facility may be expanded (or a new term loan facility or revolving credit facility added to the existing facilities) by up to greater of (x) $627 million and (y) 100% of consolidated EBITDA of Booz Allen Hamilton, as of the end of the most recently ended four quarter period for which financial statements have been delivered pursuant to the Credit Agreement plus (ii) the aggregate principal amount under which pro forma consolidated net secured leverage remains less than or equal to 3.50:1.00.

At Booz Allen Hamilton’s option, borrowings under the Secured Credit Facility bear interest based either at LIBOR (adjusted for maximum reserves, and subject to a floor of zero) for the applicable interest period or a base rate (equal to the highest of (x) the administrative agent’s prime corporate rate, (y) the overnight federal funds rate plus 0.50% and (z) three-month LIBOR (adjusted for maximum reserves, and subject to a floor of zero) plus 1.00%), in each case plus an applicable margin, payable at the end of the applicable interest period and in any event at least quarterly. The applicable margin for Term Loan A and borrowings under the Revolving Credit Facility ranges from 1.25% to 2.00% for LIBOR loans and 0.25% to 1.00% for base rate loans, in each case based on Booz Allen Hamilton’s consolidated total net leverage ratio. The applicable margin for Term Loan B is 2.00% for LIBOR loans and 1.00% for base rate loans. Unused commitments under the Revolving Credit Facility were, from the effective date of the Sixth Amendment until the delivery of financial statements for the first full fiscal quarter ending after the Sixth Amendment effective date pursuant to the Credit Agreement, subject to a quarterly fee of 0.25% and are, following such delivery of financial statements, subject to a quarterly fee ranging from 0.20% to 0.35% based on Booz Allen Hamilton’s consolidated total net leverage ratio. Until the Delayed Draw Facility was drawn down on April 23, 2019, commitments under the Delayed Draw Facility were subject to a quarterly fee ranging from 0.20% to 0.35% based on Booz Allen Hamilton's consolidated total net leverage ratio.

Booz Allen Hamilton occasionally borrows under the Revolving Credit Facility in anticipation of cash demands. During fiscal 2019 and 2018, Booz Allen Hamilton accessed a total of $110.0 million and $125.0 million, respectively, of its $500.0 million Revolving Credit Facility. As of March 31, 2019 and 2018, there was no outstanding balance on the Revolving Credit Facility.

The Credit Agreement, as amended, requires quarterly principal payments of 1.25% of the stated principal amount of Term Loan A until maturity, and quarterly principal payments of 0.25% of the stated principal amount of Term Loan B until maturity.

The Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants include limitations on the following, in each case subject to certain exceptions: (i) indebtedness and liens, (ii) mergers, consolidations or amalgamations, liquidations, wind-ups or dissolutions, and disposition of all or substantially all assets; (iii) dispositions of property; (iv) restricted payments; (v) investments; (vi) transactions with affiliates; (vii) change in fiscal periods; (viii) negative pledges; (ix) restrictive agreements; (x) line of business; and (xi) speculative hedging. The events of default include the following, in each case subject to certain exceptions: (a) failure to make required payments under the Secured Credit Facility; (b) material breaches of representations or warranties under the Secured Credit Facility; (c) failure to observe covenants or agreements under the Secured Credit Facility; (d) failure to pay or default under certain other material indebtedness; (e) bankruptcy or insolvency; (f) certain Employee Retirement Income Security Act, or ERISA events; (g) certain material judgments; (h) actual or asserted invalidity of the Guarantee and Collateral Agreements or the other security documents or failure of the guarantees or perfected liens thereunder; and (i) a change of control. In addition, Booz Allen Hamilton is required to meet certain financial covenants at each quarter end, namely

Consolidated Net Total Leverage and Consolidated Net Interest Coverage Ratios. As of March 31, 2019 and 2018, Booz Allen Hamilton was in compliance with all financial covenants associated with its debt and debt-like instruments.

During fiscal 2019, interest payments of $41.9 million and $16.8 million were made for Term Loan A and Term Loan B, respectively. During fiscal 2018, interest payments of $38.1 million and $14.9 million were made for Term Loan A and Term Loan B, respectively.

Senior Notes

On April 25, 2017, Booz Allen Hamilton issued $350 million aggregate principal amount of its 5.125% Senior Notes (the "Senior Notes"), under an Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, certain subsidiaries of Booz Allen Hamilton, as guarantors (the "Subsidiary Guarantors"), and Wilmington Trust, National Association, as trustee, (the "Trustee"), as supplemented by the First Supplemental Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, the Subsidiary Guarantors and the Trustee. Each of Booz Allen Hamilton's existing and future domestic restricted subsidiaries that guarantee its obligations under the Secured Credit Facility and certain other indebtedness guarantee the Senior Notes on a senior unsecured basis. Interest is payable semi-annually on May 1 and November 1 of each year, beginning on November 1, 2017, and principal is due at maturity on May 1, 2025. In connection with the Senior Notes, the Company recognized $6.7 million of issuance costs, which were recorded as an offset against the carrying value of debt and will be amortized to interest expense over the term of the Senior Notes. During fiscal 2019 and 2018, interest payments of $17.9 million and $9.3 million were made for the Senior Notes.

Borrowings under the Term Loans, and if used, the Revolving Credit Facility, incur interest at a variable rate. In accordance with Booz Allen Hamilton's risk management strategy, Booz Allen Hamilton executed a series of interest rate swaps. As of March 31, 2019, Booz Allen Hamilton had interest rate swaps with an aggregate notional amount of $600 million. These instruments hedge the variability of cash outflows for interest payments on the floating potion of the term loan debt. The Company's objectives in using cash flow hedges are to reduce volatility due to interest rate movements and to add stability to interest expense (See Note 13 in our consolidated financial statements).

The following table summarizes required future debt principal repayments (in thousands):

Credit Facility is recorded as a long-term asset on the consolidated balance sheet and amortized ratably over the term of the Revolving Credit Facility.

13. DERIVATIVES

The Company utilizes derivative financial instruments to manage interest rate risk related to its variable rate debt. The Company’s objectives in using these interest rate derivatives, which were designated as cash flow hedges, are to manage its exposure to interest rate movements and reduce volatility to interest expense. During the third quarter of fiscal 2019, the Company entered into three forward starting floating-to-fixed interest rate swap agreements with three financial institutions with a start date of April 30, 2019, with an aggregate notional amount of $150 million. The aggregate notional amount of all interest rate swap agreements increased to $600 million as of March 31, 2019. The swaps have staggered maturities, ranging from June 30, 2021 to June 30, 2023. These swaps mature within the last tranche of the Company's floating rate debt (July 23, 2023).

The floating-to-fixed interest rate swaps involve the exchange of variable interest amounts from a counterparty for the Company making fixed-rate interest payments over the life of the agreements without exchange of the underlying notional amount and effectively converting a portion of the variable rate debt into fixed interest rate debt.

Derivative instruments are recorded in the consolidated balance sheet on a gross basis at estimated fair value. As of March 31, 2019, $1.8 million, $0.6 million, $0.9 million, and $4.3 million were classified as other current assets, other long-term assets, other current liabilities, and other long-term liabilities, respectively, on the consolidated balance sheet. As of March 31, 2018, $0.7 million and $7.2 million were classified as other current assets and other long-term assets, respectively, on the consolidated balance sheet.

For interest rate swaps designated as cash flow hedges, the changes in the fair value of derivatives is recorded in Accumulated Other Comprehensive Income, or AOCI, net of taxes, and is subsequently reclassified into interest expense in the period that the hedged forecasted interest payments are made on the Company's variable-rate debt. The effect of derivative instruments on the accompanying consolidated financial statements for fiscal years ended March 31, 2019 and 2018 is as follows:

Derivatives in Cash Flow Hedging Relationships	Amount of Gain or (Loss) Recognized in AOCI on Derivative					Location of Gain or Loss Recognized in Income on Derivative	Amount of Gain or (Loss) Reclassified from AOCI into Income				Interest Expense on Consolidated Statements of Operations
	2019			2018			2019		2018		2019			2018
Interest rate swaps	$	(9,772	)	$	7,926	Interest expense	$	1,026	$	—	$	(89,517	)	$	(82,269	)

Over the next 12 months, the Company estimates that $0.9 million will be reclassified as a decrease to interest expense. Cash flows associated with periodic settlements of interest rate swaps will be classified as operating activities in the consolidated statement of cash flows.

The Company is subject to counterparty risk in connection with its interest rate swap derivative contracts. Credit risk related to a derivative financial instrument represents the possibility that the counterparty will not fulfill the terms of the contract. The Company mitigates this credit risk by entering into agreements with credit-worthy counterparties and regularly reviews its credit exposure and the creditworthiness of the counterparties.

14. INCOME TAXES

On December 22, 2017, Public Law No. 115-97, commonly referred to as the 2017 Tax Act, was enacted into law. The 2017 Tax Act included a number of changes to existing U.S. tax laws that impacted the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018. In addition, as a result of the tax rate change, the Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%.

In the third quarter of fiscal 2019 the Company completed its assessment for the income tax effects of the 2017 Tax Act, including true-up to all provisional amounts previously recorded, within the allowed one-year measurement period provided for under SAB118. Pursuant to SAB118, the Company finalized adjustments to provisional estimates as a reduction in the provision for income taxes of approximately $27.9 million that was primarily due to the measurement-period adjustment associated with an unbilled receivables methodology change effective as of March 31, 2018, which was approved by the IRS in the third quarter of fiscal 2019. All other adjustments to the provisional estimates that the Company recorded through the interim periods of fiscal 2019, such as the acceleration of depreciation and the limitation on the deductibility of certain executive compensation, were not material.

The components of income tax expense were as follows:

	Fiscal Year Ended March 31,

A reconciliation of the provision for income tax to the amount computed by applying the statutory federal income tax rate to income from continuing operations before income taxes for each of the three years ended March 31 is as follows:

(1) The U.S. federal statutory income tax rates for fiscal 2019, 2018 and 2017 are 21%, 31.5% and 35%, respectively.

Total deferred income tax liabilities	(211,833		)	(171,045		)
Net deferred income tax asset (liability)	$	(33,238	)	$	(7,274	)

Deferred tax balances arise from temporary differences between the carrying amount of assets and liabilities and their tax basis and are stated at the enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided against deferred tax assets when it is more likely than not that some or all of the deferred tax asset will not be realized. In determining if the Company's deferred tax assets are realizable, management considers all positive and negative evidence, including the history of generating financial reporting earnings, future reversals of existing taxable temporary differences, projected future taxable income, as well as any tax planning strategies.

As of March 31, 2019, the Company has available federal, state, and foreign net operating loss ("NOL carryforwards") of $2.3 million, $0.4 million and $1.9 million, respectively, that may be applied against future taxable income. The net operating losses are primarily attributable to an acquisition and will begin to expire in fiscal 2037. A valuation allowance of $2.9 million related to net operating losses, has been recorded due to the uncertainty regarding the realization of the asset.

Uncertain Tax Positions

The Company maintains reserves for uncertain tax positions related to unrecognized income tax benefits. These reserves involve considerable judgment and estimation and are evaluated by management based on the best information available including changes in tax laws and other information. As of March 31, 2019, 2018, and 2017, the Company has recorded $11.5 million, $11.8 million, and $11.6 million, respectively, of reserves for uncertain tax positions which includes potential tax benefits of $11.1 million, $11.6 million, and $1.4 million, respectively, that, when recognized, impact the effective tax rate.

A reconciliation of the beginning and ending amount of potential tax benefits for the periods presented is as follows:

	March 31,
	2019			2018			2017
Beginning of year	$	11,608		$	11,588		$	1,449

Lapse of statute of limitations	(462		)	(21		)	(266		)
End of year	$	11,083		$	11,608		$	11,588

The Company recognized (released) accrued interest and penalties of $0.2 million, $0.1 million and $(9) thousand for fiscal 2019, 2018, and 2017, respectively, related to the reserves for uncertain tax positions in the income tax provision. Included in the total reserve for uncertain tax positions are accrued penalties and interest of approximately $0.4 million, $0.2 million and $0.1 million at March 31, 2019, 2018, and 2017, respectively.

The Company is subject to taxation in the United States and various state and foreign jurisdictions. As of March 31, 2019, the Company's federal income tax returns and refund claims examination for fiscal years 2013 through 2015 has been completed by the IRS, resulting in an acceptance of the fully claimed amount of $10.9 million. The remaining jurisdictions' returns open for examination are not considered to be material.

The Company is currently contesting tax assessments from the District of Columbia Office of Tax and Revenue for fiscal years 2013 through 2015 at various stages of applicable administrative and judicial processes, with a combined amount at issue of approximately $11.4 million, net of associated tax benefits as of March 31, 2019. The Company has taken similar tax positions with respect to subsequent fiscal years, totaling in aggregate $27.4 million. As of March 31, 2019, the Company does not maintain reserves for any uncertain tax positions related to the contested tax benefits or the similar tax positions taken in the subsequent fiscal years. Given the Company's position on the recoverable nature of the state tax expense, it does not believe the resolution of these matters will have a material adverse effect on its results of operations, cash flows or financial condition.

15. EMPLOYEE BENEFIT PLANS

Defined Contribution Plan

The Company sponsors the Employees’ Capital Accumulation Plan, or ECAP, which is a qualified defined contribution plan that covers eligible U.S. and international employees. ECAP provides for distributions, subject to certain vesting provisions, to participants by reason of retirement, death, disability, or termination of employment. Effective April 1, 2014, the Company transitioned from a discretionary employer contribution to an annual matching contribution of up to 6% of eligible annual income as determined by the Internal Revenue Code for the ECAP. Total expense recognized under ECAP for fiscal 2019, 2018, and 2017 was $136.3 million, $126.9 million, and $116.6 million, respectively, and the Company-paid contributions were $130.9 million, $123.9 million, and $114.8 million, respectively.

Defined Benefit Plan and Other Postretirement Benefit Plans

The Company provides postretirement healthcare benefits to former officers under a medical indemnity insurance plan, with premiums paid by the Company. This plan is referred to as the Officer Medical Plan. The Company also established a non-qualified defined benefit plan for all officers in May 1995, or the Retired Officers' Bonus Plan, which pays a lump-sum amount of $10,000 per year of service as an officer, provided the officer meets retirement vesting requirements. In addition, the Company provides a fixed annual allowance after retirement to cover financial counseling and other expenses. The Retired Officers' Bonus Plan is not salary related, but rather is based primarily on years of service. During fiscal 2017, the Company adopted a new plan which will provide for a one-time, lump sum retirement payment of one month’s salary when a vice-president retires from the Company, effective April 1, 2017. This is referred to as the Retired Vice-President Bonus Plan.

The Company recognizes a liability for the defined benefit plans' underfunded status, measures the defined benefit plans' obligations that determine its funded status as of the end of the fiscal year, and recognizes as a component of accumulated other comprehensive income the changes in the defined benefit plans' funded status that are not recognized as components of net periodic benefit cost.

The components of net postretirement medical expense for the Officer Medical Plan were as follows:

Total defined benefit plan expense, consisting of service, interest, and net actuarial gain associated with the Retired Officers' Bonus Plan was $0.7 million for fiscal 2019, 2018, and 2017. Benefits paid associated with the Retired Officers’ Bonus Plan were $0.8 million, $1.5 million, and $0.9 million for fiscal 2019, 2018, and 2017, respectively. The end-of-period benefit obligation of $3.7 million and $3.8 million as of March 31, 2019 and 2018, respectively, is included in postretirement obligations within other long-term liabilities in the accompanying consolidated balance sheets.

Total defined benefit plan expense, consisting of service, interest, prior service cost, and net actuarial gain associated with the Retired Vice-President Bonus Plan was $0.2 million for fiscal 2019 and 2018. There was no defined benefit plan expense associated with the Retired Vice-President Bonus Plan for fiscal 2017. There were no benefits paid associated with the Retired Vice-President Bonus Plan for fiscal 2019, 2018, and 2017, respectively. The end-of-period benefit obligation associated with the Retired Vice-President Bonus Plan was $0.9 million as of March 31, 2019 and 2018, which are recorded as postretirement obligations within other long-term liabilities in the accompanying consolidated balance sheets.

Other comprehensive loss for fiscal 2019 includes unrecognized gross actuarial gain and prior service cost of $13.9 million, reduced by taxes of $3.6 million, that has not yet been recognized in net periodic pension cost for fiscal 2019 for the Retired Officers’ Bonus Plan, the Officer Medical Plan, and the Retired Vice-President Bonus Plan. Other comprehensive loss for fiscal 2018 includes unrecognized gross actuarial gain and prior service cost of $2.7 million, reduced by taxes of $1.0 million, that has not yet been recognized in net periodic pension cost for fiscal 2018 for the Retired Officers’ Bonus Plan, the Officer Medical Plan, and the Retired Vice-President Bonus Plan.

The changes in the benefit obligation, plan assets, and funded status of the Officer Medical Plan were as follows:

	Fiscal Year Ended March 31,
	2019			2018			2017
Benefit obligation, beginning of the year	$	126,886		$	118,089		$	114,008
Service cost	5,952			4,464			4,851
Interest cost	5,130			5,008			4,782
Net actuarial (gain) loss	(13,885		)	2,744			(2,219		)

Benefit obligation, end of the year	$	120,341		$	126,886		$	118,089

The net benefit obligation gain in fiscal 2019 was due mainly to the favorable medical cost experience in the past year as well as updates to demographic assumptions. The net benefit obligation loss in fiscal 2018 was due largely to a decrease in the discount rate and an updated outlook of higher future medical inflation offset by favorable medical cost experience in the past year. The net benefit obligation gain in fiscal 2017 was due to an increase in the discount rate as well as an update to mortality improvement assumptions.

As of March 31, 2019 and 2018, the unfunded status of the Officer Medical Plan was $120.2 million and $126.9 million, respectively, which is included in other long-term liabilities in the accompanying consolidated balance sheets.

Funded Status for Defined Benefit Plans

Generally, annual contributions are made at such times and in amounts as required by law and may, from time to time, exceed minimum funding requirements. The Retired Officers’ Bonus Plan and the Retired Vice-President Bonus Plan are unfunded plans and contributions are made as benefits are paid. As of March 31, 2019 and 2018, there were no plan assets for either the Retired Officers’ Bonus Plan or the Retired Vice-President Bonus Plan and therefore, the accumulated liability of $4.6 million and $4.7 million, respectively, is unfunded. The liability will be distributed in a lump-sum payment as each officer or vice-president retires.

2022	$	4,403
2023	$	5,231

Long-term Disability Benefits

The Company offers medical and dental benefits to inactive employees (and their eligible dependents) on long-term disability. These benefits do not vary with an employee's years of service; therefore, the Company is required to accrue the costs of the benefits at the date the inactive employee becomes disability eligible and elects to participate in the benefit. The accrued cost for such benefits is calculated using an actuarial estimate. The accrued cost for these benefits was $11.6 million and $22.8 million at March 31, 2019 and 2018, respectively, and are presented in other long-term liabilities in the accompanying consolidated balance sheets.

During the third quarter of fiscal 2019, the long-term disability plan was amended to make Medicare the first payer of eligible medical benefits, with any excess benefits becoming the obligation of the Company. The amendment caused a re-measurement of the plan liability during the period resulting in a reduction of $11.2 million recorded in general and administrative expenses.

Deferred Compensation Plan

The Company established a non-qualified deferred compensation plan (the "Plan") for certain executives and other highly compensated employees that was effective in fiscal 2018. Pursuant to the Plan, participants are eligible to defer up to 100% of their incentive cash compensation on a tax deferred basis in excess of the IRS limits imposed on 401(k) plans. The assets of the plan are held in a consolidated trust and are subject to the claims of the Company's general creditors under federal and state laws in the event of insolvency. Consequently, the trust qualifies as a Rabbi trust for income tax purposes.

As of March 31, 2019, $3.2 million of plan investments and obligations were recorded in other long term assets and in other long term liabilities, respectively, in the condensed consolidated balance sheets, representing the fair value related to the deferred compensation plan. Adjustments to the fair value of the plan investments and obligations are recorded in operating expenses.

derivative instruments as noted in Note 13 for the comparative periods. See also Notes 15 and 20, respectively, to our consolidated financial statements.

18. STOCKHOLDERS’ EQUITY

Common Stock

Holders of Class A Common Stock are entitled to one vote for each share.

Each share of common stock is entitled to participate equally in dividends, when and if declared by the Board of Directors from time to time, such dividends and other distributions in cash, stock, or property from the Company’s assets or funds become legally available for such purposes subject to any dividend preferences that may be attributable to preferred stock that may be authorized. The Company’s ability to pay dividends to stockholders is limited as a practical matter by restrictions in the credit agreements governing the Senior Credit Facilities.

The authorized and unissued Class A Common Stock shares are available for future issuance upon share option exercises, without additional stockholder approval.

Employee Stock Purchase Plan

In connection with the Company’s initial public offering in November 2010, the Company established a tax qualified Employee Stock Purchase Plan, or ESPP, which is designed to enable eligible employees to periodically purchase shares of the Company’s Class A Common Stock up to an aggregate of 10,000,000 shares at a five percent discount from the fair market value of the Company’s common stock. The ESPP provides for quarterly offering periods, the first of which commenced on April 1, 2011. For the year ended March 31, 2019, 242,706 Class A Common Stock shares were purchased by employees under the ESPP. Since the program's inception, 2,431,993 shares have been purchased by employees.

Share Repurchase Program

On December 12, 2011, the Board of Directors approved a $30.0 million share repurchase program, to be funded from cash on hand. A special committee of the Board of Directors was appointed to evaluate market conditions and other relevant factors and initiate repurchases under the program from time to time. On January 27, 2015, January 25, 2017, November 2, 2017, and May 24, 2018, the Board of Directors approved increases to the share repurchase authorization to $180.0 million, $410.0 million, $610.0 million, and $910.0 million, respectively. The share repurchase program may be suspended, modified or discontinued at any time at the Company’s discretion without prior notice. During fiscal 2019, the Company purchased 5.1 million shares of the Company’s Class A Common Stock in a series of open market transactions for $239.8 million. During fiscal 2018, the Company purchased 7.2 million shares of the Company’s Class A Common Stock in a series of open market transactions for $257.6 million. As of March 31, 2019, the Company had $258.2 million remaining under the repurchase program.

Dividends

Equity Incentive Plan

The Company's Equity Incentive Plan, or EIP, was adopted in connection with the Merger Agreement for employees and directors of Holding. The EIP was amended and restated in 2010 in connection with the Company’s initial public offering, and was again amended and restated on May 22, 2014. Awards under the EIP may be made in the form of stock options; stock purchase rights; restricted stock; restricted stock units; performance shares; performance units; stock appreciation rights; deferred share units; dividend equivalents; and other stock-based awards.

Stock Options

F-34

BOOZ ALLEN HAMILTON HOLDING CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

Stock options under the EIP are granted at the discretion of the Board of Directors or its Compensation Committee and expire ten years from the grant date. Stock options generally vest in equal installments over a five-year period subject to the grantee’s continued service on each applicable vesting. All options under the EIP are exercisable, upon vesting, for shares of Class A common stock of Holding. The following table summarizes options granted under the Amended and Restated Equity Incentive Plan, or EIP during fiscal 2019:

Grant Date	Options Granted	Estimated Fair Value per Option Grant		Total Fair Value
May 23, 2018	203,040	$	9.36	$	1,900
July 25, 2018	4,737	10.55		50
July 30, 2018	29,096	10.31		300

January 29, 2019	56,967	9.65		550
	356,679			$	3,450

The aggregate grant date fair value of the EIP Options issued during fiscal 2019 and 2018, was $3.5 million and $3.7 million, respectively, and is being recorded as expense over the vesting period. The total fair value of EIP Options vested during fiscal 2019 and 2018 was $2.5 million and $2.7 million, respectively. The total intrinsic value of EIP options exercised during fiscal 2019 and 2018 was $47.2 million and $36.7 million, respectively. As of March 31, 2019 and 2018, there were 10,708,159 and 11,434,181 options, respectively, available for future grant under the EIP.

Annual Incentive Plans

On October 1, 2010, the Board of Directors adopted an Annual Incentive Plan (or “AIP”) in connection with the initial public offering to more appropriately align the Company’s compensation programs with those of similarly situated companies. The amount of the annual incentive payment is determined based on performance targets established by the Board of Directors and a portion of the bonus may be paid in the form of equity (including stock and other awards under the EIP). For bonus periods prior to the 2018 fiscal year, if the Board of Directors elected to make a portion of the payments in equity, the value of the portion of the AIP award paid in equity was increased by 20%. Such equity awards vest over a three-year period subject to the employee’s continued service to the Company. The portion paid in the form of equity was recognized in the accompanying consolidated statements of operations based on grant date fair value over the vesting period of three years. The portion paid in cash was accrued ratably during the fiscal year in which the employees provide service and paid out during the first quarter of the subsequent fiscal year.

During fiscal 2018, the Company implemented a new annual incentive program for officers. The equity compensation would be issued in the form of restricted stock units of which a portion would vest based on the passage of time, and the other portion would vest based on specified performance conditions to be achieved over a specified time period. A restricted stock unit represents a contingent right to receive one share of Class A Common Stock upon vesting. Service-based restricted stock units vest in equal installments over a three-year period subject to the grantee's continued service on each applicable vesting date and are settled for shares of the Company's common stock. Dividend equivalents are paid in respect of the service-based restricted stock units when dividends are paid on the Company's common stock. Performance-based awards vest at the end of a three-year period subject to certain specified financial performance criteria and the grantee's continued service through the period. These awards are settled for Company Class A Common Stock and dividend equivalents. Compensation expense for performance-based awards during the performance period is estimated at each reporting date using management's expectation of the probable achievement of the specified performance criteria.

Grants of Class A Restricted Common Stock and Restricted Stock Units

During fiscal 2019, the Board of Directors granted an aggregate of 610,477 Restricted Stock Units with service-based and performance-based vesting conditions to existing officers and vice presidents of the Company, as well as to newly promoted and hired partners and vice presidents. A portion of these awards were issued in conjunction with the Annual Incentive Plan,

F-35

BOOZ ALLEN HAMILTON HOLDING CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

whereby a portion of the incentive payment was paid in the form of Restricted Stock Units. The awards issued to newly hired and promoted employees will vest over a three-year period subject to the employees' continued employment with the Company.

The Board of Directors also granted 44,420 shares of Class A Restricted Common Stock to members of the Board of Directors during fiscal 2019. These awards generally vest over one year.

The aggregate fair value of all awards issued during fiscal 2019 was $27.8 million and was based on the grant date stock price, which ranged from $41.28 to $51.82. This amount will be recognized in the accompanying consolidated statements of operations over the applicable vesting period of the awards.

The total fair value of restricted stock shares vested during fiscal 2019 and 2018 was $21.5 million and $26.7 million, respectively.

As permitted under the terms of the EIP, the Compensation Committee, as Administrator of the Plan, authorized the withholding of taxes not to exceed the minimum statutory withholding amount, through the surrender of shares of Class A common stock issuable upon the vesting or accelerated vesting of Restricted Stock. As a result of these transactions, the Company repurchased 198,231 shares and recorded them as treasury shares at a total cost of $10.2 million in fiscal 2019.

Methodology

The Company uses the Black-Scholes option-pricing model to determine the estimated fair value for stock-based awards. The fair value of the Company’s stock is based on the closing price on the New York Stock Exchange on the date of grant.

During fiscal 2019, the Company’s Board of Directors authorized and declared three quarterly cash dividends of $0.19 per share and one quarterly cash dividend of $0.23 per share. Therefore, an annualized dividend yield between 1.66% and 2.46% was used in the Black-Scholes option-pricing model for all grants issued during the fiscal year. The Company plans to continue paying recurring dividends in the near term and assessing its excess cash resources to determine the best way to utilize its excess cash flow to meet its objectives. One way the Company may utilize excess cash includes the payment of special dividends. The Company does not anticipate or forecast the payment of special dividends and therefore does not include special dividends in the annual dividend yield that the company uses to calculate the fair value of stock options, as the Company does not pay these special dividends on a regular basis.

Implied volatility is calculated as of each grant date based on our historical volatility. Other than the expected life of the option, volatility is the most sensitive input to our option grants.

The risk-free interest rate is determined by reference to the U.S. Treasury yield curve rates with the remaining term equal to the expected life assumed at the date of grant. The average expected life is calculated based on the Company's historical experience with respect to its stock plan activity in combination with an estimate of when vested and unexercised option shares will be exercised. Forfeitures were estimated based on the Company’s historical analysis of officer and vice-president attrition levels and actual forfeiture rates by grant date.

The weighted average assumptions used in the Black-Scholes option-pricing model for stock option awards were as follows:

	For The Fiscal Year Ended March 31,
	2019			2018			2017
Dividend yield	2.01		%	1.90		%	1.94		%
Expected volatility	25.83		%	33.04		%	29.65		%

20. FAIR VALUE MEASUREMENTS

The accounting standard for fair value measurements establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3).

A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The financial instruments measured at fair value in the accompanying consolidated balance sheets consist of the following:

	Recurring Fair Value Measurements as of March 31, 2019
	Level 1		Level 2		Level 3		Total

Current derivative instruments (1)	$	—	$	1,790	$	—	$	1,790

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

(1) The Company’s interest rate swaps are considered over-the-counter derivatives and fair value is estimated based on the present value of future cash flows using a model-derived valuation that uses Level 2 observable inputs such as interest rate yield curves. See Note 13 to our consolidated financial statements for further discussion on the Company’s derivative instruments designated as cash flow hedges.

(2) Investments in this category consist of primarily of mutual funds whose fair values are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. These assets represent investments held in a consolidated trust to fund the Company's non-qualified deferred compensation plan and are recorded in other long-term assets and other long-term liabilities on our consolidated balance sheets.

(3) The Company recognized a contingent consideration liability of 3.6 million in connection with the acquisition of Aquilent in fiscal 2017. As of March 31, 2019 and 2018, the estimated fair value of the contingent consideration liability was $1.2 million and $3.6 million, respectively, and was valued using probability-weighted cash flows, which is based on the use of Level 3 fair value measurement inputs. The fair value of the contingent consideration decreased by $2.4 million as the Company finalized the indemnification payments to the selling shareholders. During the third quarter of fiscal 2019, the Company recorded the decrease of payments in other income as a result of the fair value change and the liability is recorded in other long-term liabilities in the consolidated balance sheet.

The fair value of the Company's cash and cash equivalents, which are primarily Level 1 inputs, approximated its carrying values at March 31, 2019 and 2018. The fair value of the Company's debt instruments approximated its carrying value at March 31, 2019 and 2018. The fair value of debt is determined using quoted prices or other market information obtained from recent trading activity of each debt tranche in markets that are not active (Level 2 inputs). The fair value is corroborated by prices derived from the interest rate spreads of recently completed leveraged loan transactions of a similar credit profile, industry, and terms to that of the Company. The fair value of Senior Notes is determined using quoted prices or other market information from recent trading activity in the high-yield bond market (Level 2 inputs).

21. RELATED-PARTY TRANSACTIONS

In March 2018, the Company supported the formation of the Booz Allen Foundation, a nonprofit corporation organized and operated exclusively for charitable, scientific and educational purposes within the meaning of Section 501(c)(3) of the Code. The Company is the sole member of the foundation, which gives it the authority to appoint two out of five of the Booz Allen Foundation’s directors and consent rights regarding certain extraordinary corporate actions approved by the Company's Board of Directors. The Company has made a binding and irrevocable pledge of $5.0 million to the Booz Allen Foundation, payable in installments, and recorded the pledge obligation in other current liabilities on the consolidated balance sheet of the Company in March 2017. As of March 31, 2019, the Company has satisfied the pledge obligation in full. The final two installment payments made to the Booz Allen Foundation in the third quarter of fiscal 2019 totaling $3.3 million are classified as operating activities in the consolidated statement of cash flows.

Two of our directors currently serve on the board of directors of a subcontractor to which the Company subcontracted $55.3 million of services for the year ended March 31, 2019.

22. COMMITMENTS AND CONTINGENCIES

Leases

The Company leases office space under noncancelable operating leases that expire at various dates through fiscal 2031. The terms for the facility leases generally provide for rental payments on a graduated scale, which are recognized on a straight-line basis over the terms of the leases, including reasonably assured renewal periods, from the time the Company controls the leased property. Sometimes lease payments include payments for insurance, maintenance, and property taxes. There are no purchase options on operating leases at terms favorable to market rents. Lease incentives are recorded as a deferred credit and recognized as a reduction to rent expense on a straight-line basis over the lease term. Rent expense was approximately $82.7 million, net of $0.6 million of sublease income, $81.2 million, net of $0.6 million of sublease income, and $81.6 million, net of $0.5 million of sublease income, for fiscal 2019, 2018, and 2017, respectively.

Future minimum operating lease payments for noncancelable operating leases and future minimum income for noncancelable sublease rentals are summarized as follows:

For the Fiscal Year Ending March 31,	Operating Lease Payments		Operating Sublease Income
2020	$	70,614	$	129
2021	68,888		12
2022	58,325		5

Thereafter	125,399		—
	$	422,911	$	146

Rent expense is included in occupancy costs, a component of general and administrative expenses, as shown on the consolidated statements of operations, and includes rent, sublease income from third parties, real estate taxes, utilities, parking, security, repairs and maintenance, and storage costs.

Letters of Credit and Third-Party Guarantees

As of March 31, 2019 and 2018, the Company was contingently liable under open standby letters of credit and bank guarantees issued by our banks in favor of third parties that totaled $9.5 million and $6.3 million, respectively. These letters of credit and bank guarantees primarily support insurance and bid and performance obligations. At March 31, 2019 and 2018, approximately $1.0 million and $1.4 million, respectively, of these instruments reduce the available borrowings under the Revolving Credit Facility. The remainder is guaranteed under a separate $15.0 million facility established in fiscal 2015 of which $6.5 million and $10.1 million, respectively, was available to the Company at March 31, 2019 and 2018.

Government Contracting Matters

For fiscal 2019, 2018, and 2017, approximately 96%, 97%, and 97%, respectively, of the Company’s revenue was generated from contracts where the end user was an agency or department of the U.S. government, including contracts where the Company performed in either as a prime contractor or subcontractor, and regardless of the geographic location in which the work was performed. U.S. government contracts and subcontracts are subject to extensive legal and regulatory requirements. From time to time and in the ordinary course of business, agencies of the U.S. government audit our contract costs and conduct inquiries and investigations of our business practices with respect to government contracts to determine whether the Company’s operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government agencies, including the Defense Contract Audit Agency, routinely audit our contract costs, including allocated indirect costs, for compliance with the Cost Accounting Standards and the Federal Acquisition Regulation. These agencies also conduct reviews and investigations and make inquiries regarding our accounting and other systems in connection with our performance and business practices with respect to our government contracts and subcontracts. U.S. government audits, inquiries, or investigations of the Company, whether related to the Company’s U.S. government contracts or subcontracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including withholding of payments, suspension of payments, repayments, fines, or penalties being imposed upon the Company, or could lead to suspension or debarment from future U.S. government contracting. Management believes it has recorded the appropriate provision for any such audit, inquiry, or investigation of which it is aware. Management believes it has recorded the appropriate provision for the estimated losses that may be experienced from any such reductions and/or penalties. As of March 31, 2019 and 2018, the Company has recorded a liability of approximately $195.3 million and $168.6 million, respectively, for its current best estimate of amounts to be refunded to customers for potential adjustments from audits or reviews of contract costs incurred subsequent to fiscal year 2011, and for contracts not yet closed that are impacted by settlement of audits or reviews of contract costs incurred in prior fiscal years.

Litigation

The Company is involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with clients and contractors, intellectual property disputes, and other business matters. These legal proceedings seek various remedies, including claims for monetary damages in varying amounts, none of which are considered material, or are unspecified as to amount. Although the outcome of any such matter is inherently uncertain and may be materially adverse, based on current information, management does not expect any of the currently ongoing audits, reviews, investigations, or litigation to have a material adverse effect on the Company’s financial condition and results of operations. As of March 31, 2019 and 2018, there were no material amounts accrued in the consolidated financial statements related to these proceedings.

Six former officers and stockholders who had departed the company prior to the acquisition of the Company by the Carlyle Group (the "Carlyle Acquisition") have filed a total of nine suits in various jurisdictions, with original filing dates ranging from July 3, 2008 through December 15, 2009, against us and certain of our current and former directors and officers. Three of these suits were amended on July 2, 2010 and then further amended into one consolidated complaint on September 7, 2010. Another two of the original nine suits were consolidated into one complaint on September 24, 2014. Each of the suits arises out of the Carlyle Acquisition and alleges that the former stockholders are entitled to certain payments that they would have received if they had held their stock at the time of the Carlyle Acquisition. Some of the suits also allege that the acquisition price paid to stockholders was insufficient. The various suits assert claims for breach of contract, tortious interference with contract, breach of fiduciary duty, civil Racketeer Influenced and Corrupt Organizations Act, or RICO, violations, violations of the ERISA, and/or securities and common law fraud. Three of these suits have been dismissed with all appeals exhausted. The two suits that were consolidated into one action on September 24, 2014 were settled on April 16, 2015. One of the remaining suits has been dismissed by the United States District Court for the Southern District of California and such dismissal was upheld by the United States Court of Appeals for the Ninth Circuit. The plaintiff in this suit subsequently filed a Petition for Writ of Certiorari to the United States Supreme Court, which was denied by the United States Supreme Court on January 9, 2017. The other three remaining suits that were previously consolidated on September 7, 2010 have been dismissed by the United States District Court for the Southern District of New York and were on appeal before the United States Court of Appeals for the Second Circuit. On July 13, 2017, the United States Court of Appeals for the Second Circuit affirmed the ruling of the United States District Court for the Southern District of New York, except for one plaintiff’s securities fraud claim, which was remanded to the United States District Court for the Southern District of New York to give the plaintiff, Paul Kocourek, leave to file another amended complaint to attempt to plead a securities fraud claim. On April 6, 2018, the plaintiff filed an amended complaint in which Mr. Kocourek, individually, as Trustee of the Paul Kocourek Trust and on behalf of the putative class, alleges that the Company and certain former officers and directors violated Sections 10(b), 20(a) and 14(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). On April 25, 2018, the court entered an order postponing the deadline within which the defendants must answer or move to dismiss the amended complaint. A lead plaintiff has not been appointed. On August 2, 2018, the defendants filed a motion to dismiss the amended complaint. On September 17, 2018, the plaintiff filed an opposition to the defendants’ motion to dismiss the amended complaint. The defendants filed their reply to plaintiff's opposition on October 17, 2018.

As of March 31, 2019, the aggregate alleged damages that will be sought in the remaining suit is unknown. As of March 31, 2019, although the outcome of any of these cases is inherently uncertain and may be materially adverse, based on current information, management does not expect them to have a material adverse effect on our financial condition and results of operations.

On June 7, 2017, Booz Allen Hamilton Inc. was informed that the U.S. Department of Justice (DOJ) is conducting a civil and criminal investigation of the Company. In connection with the investigation, the DOJ has requested information from the Company relating to certain elements of the Company’s cost accounting and indirect cost charging practices with the U.S. government. Since learning of the investigation, the Company has engaged a law firm experienced in these matters to represent the Company in connection with this matter and respond to the government's requests. As is commonly the case with this type of matter, the Company has also been in contact with other regulatory agencies and bodies, including the Securities and Exchange Commission, which notified the Company that it is conducting an investigation that the Company believes relates to matters that are also the subject of the DOJ's investigation. The Company may receive additional regulatory or governmental inquiries related to the matters that are the subject of the DOJ's investigation. In accordance with the Company's practice, the company is cooperating with all relevant government parties. The total cost associated with these matters will depend on many factors, including the duration of these matters and any related findings. At this stage, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with these matters.

On June 19, 2017, a purported stockholder of the Company filed a putative class action lawsuit in the United States District Court for the Eastern District of Virginia styled Langley v. Booz Allen Hamilton Holding Corp., No. 17-cv-00696 naming the Company, its Chief Executive Officer and its Chief Financial Officer as defendants purportedly on behalf of all purchasers of the Company’s securities from May 19, 2016 through June 15, 2017. On September 5, 2017, the court named two lead plaintiffs and on October 20, 2017, the lead plaintiffs filed a consolidated amended complaint. The complaint asserts claims under Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 promulgated thereunder, alleging misrepresentations or omissions by the Company purporting to relate to matters that are the subject of the DOJ investigation described above. The plaintiffs seek to recover from the Company and the individual defendants an unspecified amount of damages. The Company believes the suit lacks merit and intends to defend against the lawsuit. Motions to dismiss were argued on January 12, 2018, and on February 8, 2018, the court dismissed the amended complaint in its entirety without prejudice. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

On November 13, 2017, a Verified Shareholder Derivative Complaint was filed in the United States District Court for the District of Delaware styled Celine Thum v. Rozanski et. al., C.A. No. 17-cv-01638, naming the Company as a nominal defendant and numerous current and former officers and directors as defendants. The complaint asserts claims for breach of fiduciary duties, unjust enrichment, waste of corporate assets, abuse of control, gross mismanagement, and violations of Sections 14(a), 10(b) and 20(a) of the Exchange Act, purportedly relating to matters that are the subject of the DOJ investigation described above. The parties have stipulated to a stay of the proceedings pending the outcome of the securities litigation (described above), which the court so ordered on January 24, 2018. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

Management’s Annual Report on Internal Control over Financial Reporting and Attestation Report of the Registered Public Accounting Firm

Our management is responsible for establishing and maintaining adequate internal control over financial reporting.

Our management conducted an assessment of the effectiveness of our internal control over financial reporting as of March 31, 2019. This assessment was based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control — Integrated Framework (2013 framework). Based on this assessment, management has concluded that, as of March 31, 2019, our internal control over financial reporting was effective.

Our independent registered public accounting firm has issued a report on the effectiveness of our internal control over financial reporting, which is below.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934, that occurred in the fourth fiscal quarter of the period covered by this Annual Report that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Ernst & Young LLP,

Independent Registered Public Accounting Firm,

Regarding Internal Control over Financial Reporting

To the Shareholders and Board of Directors of

Booz Allen Hamilton Holding Corporation

Opinion on Internal Control over Financial Reporting

We have audited Booz Allen Hamilton Holding Corporation’s internal control over financial reporting as of March 31, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Booz Allen Hamilton Holding Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of March 31, 2019, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of March 31, 2019 and 2018, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended March 31, 2019, and the related notes and our report dated May 28, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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

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

Exhibit 4.5

DESCRIPTION OF CAPITAL STOCK

The following descriptions of our capital stock and provisions of our third amended and restated certificate of incorporation, which we refer to as our amended and restated certificate of incorporation, and third amended and restated bylaws, which we refer to as our amended and restated bylaws, are summaries of their material terms and provisions. For a complete description of our capital stock, amended and restated certificate of incorporation and amended and restated bylaws, please refer to our amended and restated certificate of incorporation, amended and restated bylaws and the applicable provisions of the Delaware General Corporation Law.

All references to “Company”, “we”, “us”, and “our” refer to Booz Allen Hamilton Holding Corporation.

Common Stock

Our amended and restated certificate of incorporation authorizes the issuance of 646,000,000 shares of common stock, which includes:

• 600,000,000 shares of Class A common stock, par value $0.01 per share;

• 16,000,000 shares of Class B non-voting common stock, par value $0.01 per share;

• 5,000,000 shares of Class C restricted common stock, par value $0.01 per share; and

• 25,000,000 shares of Class E special voting common stock, par value $0.003 per share.

The shares of common stock issued and outstanding are as follows:

	As of May 22,
	2019
Class A common stock		140,030,725
Class B non-voting common stock		0
Class C restricted common stock		0
Class E special voting common stock		0
Total shares outstanding		140,030,725

The amended and restated certificate of incorporation currently authorizes the issuance of shares of Class A common stock, Class B non-voting common stock, Class C restricted common stock and Class E special voting common stock. At our annual meeting of stockholders held on July 31, 2014, our stockholders approved a proposal to amend and restate our certificate of incorporation, which had the effect of converting all issued and outstanding shares of Class B non-voting common stock and Class C restricted common stock into shares of Class A common stock on a one-for-one basis. The conversion was effected on August 13, 2014 when we filed our third amended and restated certificate of incorporation with the Secretary of State of the State of Delaware. As a result of the conversion, there were no shares of Class B non-voting common stock and Class C restricted common stock outstanding at the time that the third amended and restated certificate of incorporation was filed, and no shares of Class B non-voting common stock or Class C restricted common stock have been issued since such time.

On September 30, 2015, we purchased, at par value, all issued and outstanding shares of Class E special voting common stock in connection with the exercise of the final tranche of rollover options during the second quarter of fiscal 2016, and no shares of Class E special voting common stock have been issued since such purchase. Accordingly, there are no shares outstanding nor is there an established trading market for any of our Class B non-voting common stock, Class C restricted common stock, or Class E special voting common stock.

The rights and privileges of holders of our common stock are subject to any series of preferred stock that we may issue in the future.

Voting Rights. Holders of Class A common stock, Class C restricted common stock and Class E special voting common stock are entitled to one vote for each share on all matters to be voted on by stockholders. Except as otherwise provided by the Delaware General Corporation Law, the holders of the voting common stock, as such, shall vote together as a single class. Except as required by the Delaware General Corporation Law, the holders of Class B non-voting common stock will have no voting rights of any nature whatsoever.

Election of Directors. Directors are elected by the vote of the majority of the votes cast (as defined in Section 2.02 of the amended and restated bylaws) with respect to such director’s election; unless the director has been duly nominated by a stockholder in accordance with the amended and restated bylaws. Where a director has been duly nominated by a stockholder in accordance with the amended and restated bylaws, such directors shall be elected by the vote of a plurality of votes cast in connection with the election of directors at any meeting of stockholders. Any nominee who is an incumbent director and does not receive a majority of the votes cast in an election where the director was not duly nominated by a stockholder in accordance with the amended and restated bylaws must promptly tender his or her resignation contingent on the acceptance of that resignation by the Company’s Board of Directors (the “Board”) pursuant to the procedure established in the amended and restated bylaws.

Dividend Rights. Each share of common stock, except for Class E special voting common stock, is entitled to participate equally, when and if declared by the Board from time to time, in such dividends and other distributions in cash, stock, or property from the Company’s assets or funds as may become legally available for such purposes subject to any dividend preferences that may be attributable to preferred stock that may be authorized and outstanding.

Right to Receive Liquidation Distributions. In the event of our liquidation, dissolution or winding up, holders of our common stock, except for Class E special voting common stock (other than to the extent of its par value), will be entitled to receive proportionately any of our assets remaining after the payment of liabilities and subject to the prior rights of any outstanding preferred stock. Because we are a holding company, our ability to pay dividends is subject to our subsidiaries’ ability to pay dividends to us, which is in turn subject to the restrictions set forth in our debt agreements.

Conversion Rights. Shares of our Class A common stock are not convertible into any other series or class of securities.

Our Class A common stock is registered on the New York Stock Exchange under the symbol “BAH”.

Preferred Stock

Our amended and restated certificate of incorporation authorizes the issuance of 54,000,000 shares of preferred stock, par value $0.01  per share, the terms and conditions of which are determined by the Board

2

upon issuance. The rights, preferences and privileges of holders of 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. As of May 22, 2019, there were no shares of preferred stock outstanding. We have no present plans to issue any shares of preferred stock.

Change of Control Related Provisions of Our Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws and Delaware Law

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws, and in the Delaware General Corporation Law, may make it difficult, expensive and time-consuming for a third party to pursue a takeover attempt even if a change in control of the Company would be beneficial to the interests of our stockholders. Any provision of our amended and restated certificate of incorporation or amended and restated bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock. These provisions are intended to:

• enhance the likelihood of continuity and stability in the composition of our Board;

• discourage some types of transactions that may involve an actual or threatened change in control of the Company;

• discourage certain tactics that may be used in proxy fights;

• ensure that our Board will have sufficient time to act in what our Board believes to be the best interests of us and our stockholders; and

• encourage persons seeking to acquire control of our company to first consult with our Board to negotiate the terms of any proposed business combination or offer.

Unissued Shares of Capital Stock

As of May 22, 2019, 140,030,725 shares of our Class A common stock were issued and outstanding. The remaining shares of authorized and unissued Class A common stock are available for future issuance without additional stockholder approval, subject to the requirements of applicable law or regulation, including any listing requirement of the principal stock exchange on which our Class A common stock is then listed. While the additional shares are not designed to deter or prevent a change of control, under some circumstances we could use the additional shares to create voting impediments or to frustrate persons seeking to effect a takeover or otherwise gain control by, for example, issuing those shares in private placements to purchasers who might side with our Board in opposing a hostile takeover bid.

In addition, our amended and restated certificate of incorporation provides our Board with the authority, without any further vote or action by our stockholders, to designate and issue one or more series of preferred stock at their sole discretion and to fix the number of shares and the preferences, limitations and relative rights of the shares constituting any series. This provision makes it possible for our Board to issue preferred stock with super voting, special approval, dividend or other rights or preferences which could impede any attempt to acquire us. These and other provisions may have the effect of deferring, delaying or discouraging hostile takeovers or changes in control or management of our company, discouraging bids for

3

the Class A common stock at a premium over the market price of the common stock and may adversely affect the market price of, and the voting and other rights of the holder of, Class A common stock.

Classified Board; Vacancies and Removal of Directors

Our amended and restated certificate of incorporation and amended and restated bylaws provide that our Board is divided into three classes whose members serve three-year terms expiring in successive years. Any effort to obtain control of our Board by causing the election of a majority of the Board may require more time than would be required without such a staggered election structure.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that directors may only be removed from office for cause upon the affirmative vote of holders of at least a majority of the votes which all the stockholders would be entitled to cast. Our amended and restated certificate of incorporation and amended and restated bylaws also provide that vacancies in our Board may be filled only by our Board. Any director elected to fill a vacancy will hold office for the remainder of the full term of the class of directors in which the vacancy occurred (including a vacancy created by increasing the size of the Board) and until such director’s successor shall have been duly elected and qualified. No decrease in the number of directors will shorten the term of any incumbent director. The number of directors shall be fixed and modified, but not reduced to less than three, from time to time by resolution of our Board.

These provisions may have the effect of slowing or impeding a third party from initiating a proxy contest, making a tender offer or otherwise attempting a change in the membership of our Board that would effect a change of control.

Advance Notice Provisions for Stockholder Nominations of Directors and Stockholder Proposals

Our amended and restated bylaws establish an advance notice procedure for stockholders to make nominations of candidates for election as director or to bring other business before an annual meeting of our stockholders. This procedure provides that, except as otherwise required by applicable law, only persons who are nominated by the Board, a committee appointed by the Board, or by a stockholder who (i) is entitled to vote at the meeting, (ii) has given timely written notice to our secretary prior to the meeting and (iii) is a stockholder of record when the required notice is delivered and at the date of the meeting, will be eligible for election as directors, and only business that has been brought before an annual meeting by the Board, any committee appointed by the Board, or by a stockholder who has given timely written notice to our secretary prior to the meeting, may be conducted. Under the procedure, to be timely, notice must be received by the secretary at our principal executive offices not less than 90 days and not more than 120 days prior to the first anniversary date of the annual meeting of the preceding year. In addition, a stockholder’s notice proposing to nominate a person for election as director must, among other things, contain specific information about the nominating stockholder and the proposed nominee as well as the proposed nominee’s written consent to be named in the proxy statement as a nominee and to serving as a director if elected. A stockholder’s notice relating to the conduct of business other than the nomination of directors must contain, among other things, specific information about the proposing stockholder, the text of the proposal, the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and beneficial owner, if any, on whose behalf the proposal is made.

Requiring advance notice of nominations by stockholders allows our Board an opportunity to consider the qualifications of the proposed nominees and also provides a more orderly procedure for conducting annual meetings of stockholders. It also provides the Board with the opportunity to inform stockholders of proposed business prior to the meeting, so that stockholders can better decide whether to attend the meeting or to grant a proxy regarding the disposition of the business. These provisions may also have the effect of

4

precluding a contest for the election of directors or the consideration of stockholder proposals and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its own proposal without regard to whether consideration of the nominees or proposals might be harmful or beneficial to us or our stockholders.

Calling Special Stockholder Meetings; Stockholder Action by Written Consent

Our amended and restated certificate of incorporation and amended and restated bylaws provide that a special meeting of stockholders may only be called by our Board. Our amended and restated bylaws provide that any action taken by the stockholders must be effected at a duly called annual or special meeting, which may be called only by the Board.

These provisions make it procedurally more difficult for a stockholder to take action without a meeting and therefore may reduce the likelihood that a stockholder will seek to take independent action with respect to matters that are not supported by management.

Supermajority Voting Requirements for Amendment of Certain Provisions of Our Amended and Restated Bylaws

Our amended and restated bylaws provide that our bylaws may be amended, altered or repealed at any regular or special meeting of the stockholders only if the amendment is approved by the vote of holders of at least two-thirds of the shares then entitled to vote at a general election of directors. In addition, amendments may be instituted by resolutions adopted by a majority of the Board at any special or regular meeting of the Board. These provisions make it more difficult for stockholders to remove or amend any provisions that may have an anti-takeover effect.

Corporate Opportunities

Our amended and restated certificate of incorporation provides that The Carlyle Group (“Carlyle”) has no obligation to offer us an opportunity to participate in business opportunities presented to Carlyle or its affiliates, including its respective officers, directors, agents, members, partners and affiliates even if the opportunity is one that we might reasonably have pursued, and that neither Carlyle nor its respective officers, directors, agents, members, partners or affiliates is liable to us or our stockholders for breach of any duty by reason of any such activities unless, in the case of any person who is a director or officer of our company, such business opportunity is expressly offered to such director or officer in writing solely in his or her capacity as an officer or director of our company. Stockholders will be deemed to have notice of and consented to this provision of our amended and restated certificate of incorporation.

Limitation of Liability of Directors; Indemnification of Directors and Officers

Our amended and restated certificate of incorporation contains provisions permitted under Delaware General Corporation Law relating to the liability of directors. These provisions eliminate a director’s personal liability for monetary damages resulting from a breach of fiduciary duty, except in circumstances involving or related to:

5

• any breach of the director’s duty of loyalty;

• acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law;

• any violation of Section 174 of the Delaware General Corporation Law (including, among other things, unlawful payment of dividends); or

• any transaction from which the director derives an improper personal benefit.

The principal effect of the limitation on liability provision is that a stockholder will be unable to prosecute an action for monetary damages against a director unless the stockholder can demonstrate a basis for liability for which indemnification is not available under the Delaware General Corporation Law. These provisions, however, should not limit or eliminate our rights or any stockholder’s rights to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of director’s fiduciary duty. These provisions will not alter a director’s liability under federal securities laws. The inclusion of this provision in our certificate of incorporation may discourage or deter stockholders or management from bringing a lawsuit against directors for a breach of their fiduciary duties, even though such an action, if successful, might otherwise have benefited us and our stockholders.

Our amended and restated bylaws require us to indemnify and advance expenses to our directors and officers to the fullest extent not prohibited by the Delaware General Corporation Law and other applicable law, except in the case of a proceeding instituted by the director without the approval of our Board. Our amended and restated bylaws also provide that we are required to indemnify our directors and officers, to the fullest extent permitted by law, for all judgments, fines, settlements, legal fees and other expenses incurred in connection with pending or threatened legal proceedings because of the director’s or officer’s positions with us or another entity that the director or officer serves at our request, subject to various conditions, and to advance funds to our directors and officers to enable them to defend against such proceedings. To receive indemnification, the director or officer must have been successful in the legal proceeding or have acted in good faith and in what was reasonably believed to be a lawful manner in our best interest and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful.

We have entered into an indemnification agreement with each of our directors and officers. The indemnification agreements provide our directors and officers with contractual rights to the indemnification and expense advancement rights provided under our amended and restated bylaws, as well as contractual rights to additional indemnification as provided in the indemnification agreement.

Any costs we pay for legal expenses (see Defense coverages) are in addition to the amount of coverage.

Group Personal Excess Liability Coverage

(continued)

We cover damages for bodily injury and property damage a covered person is legally entitled to receive from the owner or operator of an uninsured motorized/underinsured motorized land vehicle. We cover these damages in excess of the underlying insurance or the Required Primary Underlying Insurance, whichever is greater, if they are caused by an occurrence during the policy period, unless otherwise stated.

Amount of coverage. The maximum amount of excess uninsured motorists/underinsured motorists protection available for any one occurrence is the excess uninsured motorists/underinsured motorists protection amount shown in the Coverage Summary regardless of the number of vehicles covered by the Required Primary Underlying Insurance. We will not pay more than this amount in any one occurrence for covered damages regardless of how many claims, vehicles or people are involved in the occurrence. This coverage will follow form.

Uninsured motorists/underinsured motorists protection arbitration

If we and a covered person disagree whether that person is legally entitled to recover damages from the owner or operator of an uninsured motor vehicle/underinsured motor vehicle, or do not agree as to the amount of damages, either party may make a written demand for arbitration. In this event, each party will select an arbitrator. The two arbitrators will select a third. If they cannot agree on a third arbitrator within 45 days, either may request that the arbitration be submitted to the American Arbitration Association. When the covered person's recovery exceeds the minimum limit specified in the applicable jurisdiction's financial responsibility law, each party will pay the expenses it incurs, and bear the expenses of the third arbitrator equally. Otherwise, we will bear all the expenses of the arbitration.

Unless both parties agree otherwise, arbitration will take place in the county and state in which the covered person lives. Local rules of law as to procedure and evidence will apply. A decision agreed to by two arbitrators will be binding unless the recovery amount for bodily injury exceeds the minimum limit specified by the applicable jurisdiction's financial responsibility law. If the amount exceeds that limit, either party may demand the right to a trial. This demand must be made within 60 days of the arbitrator's decision. If this demand is not made, the amount of damages agreed to by the arbitrators will be binding.

This coverage is excess over the total of any other collectible insurance that covers damages from the occurrence.

All the exclusions under the Group Personal Excess Liability Coverage are applicable to this Uninsured/underinsured liability coverage, and where used, the definition of you or a family member is extended to include negligent person. This coverage also does not apply to damages from an occurrence arising out of any business activities; any activities involving business property or the sale or transfer of property; or the ownership, maintenance, use, loading, unloading, or towing of any motor vehicle, watercraft, or aircraft.

(b)To the extent permitted by law or the applicable listing rules, if any, the Optionee may pay for the Shares with respect to which such Option or portion of such Option is exercised through (i) payment in cash; (ii) with the consent of the Administrator, the delivery of Shares which are owned by the Optionee, duly endorsed for transfer to the Company with a Fair Market Value on the date of delivery equal to the aggregate Exercise Price of the exercised portion of the Option; (iii) with the consent of the Administrator, through the surrender of Shares then issuable upon exercise of the Option having a Fair Market Value on the date of the exercise of the Option equal to the aggregate Exercise Price of the exercised portion of the Option; or (iv) with the consent of the Administrator, delivery of a notice that the Optionee has placed a market sell order with a broker with respect to Shares then-issuable upon exercise of the Option, and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in satisfaction of the aggregate Exercise Price; provided, that payment of such proceeds is then made to the Company upon settlement of such sale.

Any adverse consequences to the Optionee arising in connection with the Share withholding procedure set forth in the preceding sentence shall be the sole responsibility of the Optionee.

Section 2.9Change in Control. Upon the occurrence of a Change in Control, the Options shall vest, forfeit or continue as set forth in Article XIII of the Plan. At the discretion of the Administrator (as constituted immediately prior to the Change in Control), any or all vested Options may be canceled in exchange for an amount equal to the product of (A) the excess, if any, of the Fair Market Value of the Shares upon the Change in Control over the exercise price for such vested Options, multiplied by (B) the aggregate number of shares of Company Common Stock covered by such vested Options.

APPENDIX A TO PERFORMANCE RESTRICTED STOCK UNIT AGREEMENT

1.Grant of Restricted Stock Units. Subject to the terms, conditions, and restrictions set forth in this Agreement (including the Grant Notice made available to you by the Company) and in the Plan, the Company hereby evidences and confirms its grant to the Participant, effective as of the Grant Date, of the target number of performance restricted stock units (the “Target Award”) specified in the Grant Notice. Each performance restricted stock unit (a “Restricted Stock Unit”) represents the right to receive between zero and two shares of Company Common Stock, subject to the terms and conditions set forth in this Agreement (including the Grant Notice) and in the Plan. Except as otherwise provided in Section 2, the number of Restricted Stock Units that the Participant shall actually earn for the Performance Period (up to the maximum specified in the Grant Notice) will be determined by the Administrator based on the level of achievement of the performance goals specified in the Grant Notice (the “Performance Goals”). This Agreement is subordinate to, and the terms and conditions of the Restricted Stock Units granted hereunder are subject to, the terms and conditions of the Plan, which are incorporated by reference herein. If there is any inconsistency between the terms hereof and the terms of the Plan, the terms of the Plan shall govern. Any capitalized terms used herein without definition shall have the meanings set forth in the Plan.

2.Vesting of Restricted Stock Units.

(a)Vesting. For purposes of this Agreement, the term “Performance Period” shall mean the period set forth in the Grant Notice. The Restricted Stock Units are subject to forfeiture until they vest. Except as otherwise provided in this Section 2, the Restricted Stock Units shall become vested as of the vesting date specified in the Grant Notice (the “Vesting Date”), subject to the continued employment or service of the Participant by the Company or any Subsidiary thereof through the Vesting Date, and to the achievement of the Performance Goals set forth in the Grant Notice for the Performance Period as determined by the Administrator pursuant to Section 3(a). Restricted Stock Units that do not vest in accordance with this Section 2 shall be forfeited.

(b)Termination of Employment.

(i)Termination Due to Death. If a Participant’s employment or service terminates due to the Participant’s death prior to the Vesting Date, all unvested Restricted Stock Units shall vest on the effective date of such termination of employment or service at Target Award levels. Vested Restricted Stock Units shall be settled as set forth in Section 3.

(ii)Termination by Reason of a Company Approved Departure; Termination by Reason of Disability. If a Participant’s employment or service terminates prior to the Vesting Date (A) by reason of a Company Approved Departure (as defined below) or (B) by reason of the Participant’s Disability, then, in each case, the Participant’s unvested Restricted Stock Units shall vest as of the Vesting Date in a pro rata amount of the Restricted Stock Units that would have been earned and vested in accordance with Section 2(a) based on actual achievement of the

Performance Goals as if the Participant’s employment or service had not terminated, with such amount prorated for the portion of the Performance Period that lapsed prior to the Participant’s termination of employment or service; provided, that, any transition period (within the meaning of the Company’s Transition Policy, as may be amended from time to time) shall not be considered a period of employment or service for purposes of calculating the pro rata amount. Vested Restricted Stock Units shall be settled as set forth in Section 3. “Company Approved Departure” shall mean a termination of employment that the Company (through the members of its senior management), in its sole discretion, determines to be in the best interest of the Company and the Company’s approval of such termination as a Company Approved Departure is approved or ratified by the Board or the Administrator.

Vested Restricted Stock Units shall be settled as set forth in Section 3. “Qualifying Permanent Retirement” means a termination of the Participant’s employment or service by reason of a retirement (I) in accordance with the applicable Company retirement policy (as may be amended from time to time) and (II) that is a permanent retirement from all current and future employment, including but not limited to self-employment, unless such employment is approved by the Company in writing in advance of the Participant commencing such employment.

(iv)Termination for Cause. If a Participant’s employment or service terminates for Cause, all unvested Restricted Stock Units shall be immediately forfeited and canceled, effective as of the date of the Participant’s termination of service. In addition, any Restricted Stock Units that vested during the twelve (12) months prior to or any time after the Participant engaged in the conduct that gave rise to the termination for Cause (and any stock or cash issued in settlement of such Restricted Stock Units) shall upon demand by the Administrator be immediately forfeited and disgorged or paid to the Company together with all gains earned or accrued due to the sale of Stock issued in settlement of any Restricted Stock Units.

Vested Restricted Stock Units shall be settled as set forth in Section 3.

Notwithstanding anything contained in this Agreement to the contrary, subject to Article XIII of the Plan, the Administrator, in its sole discretion, may waive forfeiture provisions or accelerate the vesting with respect to any Restricted Stock Units under this Agreement, at such times and upon such terms and conditions as the Administrator shall determine; provided, however, that such waiver or acceleration of vesting shall not change the settlement date of the Restricted Stock Units provided in Section 3 of this Agreement.

(f)Post-Termination Informational Requirements. Before the settlement of any Restricted Stock Units following termination of employment or service, the Company may require the Participant (or the Participant’s Eligible Representative, if applicable) to make such representations and provide such documents as the Administrator deems necessary or advisable

to determine whether the provisions of Section 2(b)(iii), 2(b)(iv) or 2(d) apply. Such representations and documents may include tax returns and all other relevant information and records from which the Company can determine the current or former employment status of the Participant during the Performance Period. Notwithstanding anything in this Agreement to the contrary, the settlement of the Restricted Stock Units may be withheld until information deemed sufficient by the Company is delivered to it, and any unvested Restricted Stock Units shall be forfeited if the requested information is not provided in sufficient detail to the Company before the earlier of (i) ninety (90) calendar days after the issue of a request from the Company for such information and (ii) December 31 of the calendar year in which the Vesting Date occurs.

3.Administrator Certification; Settlement of Restricted Stock Units.

(a)Certification. As soon as practicable following completion of the Performance Period, the Administrator will review and determine (i) whether, and to what extent, the Performance Goals for the Performance Period have been achieved, in whole or in part, and (ii) the number of Restricted Stock Units that the Participant shall earn, if any, subject to compliance with the requirements of Section 2 (the “Administrator Certification”). All determinations of whether the Performance Goals have been achieved, the number of Restricted Stock Units earned by the Participant, and all other matters related to this Section 3(a) shall be made by the Administrator in its sole discretion and shall be final, conclusive and binding on the Participant.

(b)Settlement of Restricted Stock Units. Subject to Sections 8(d), 2(f) and 3(a), the Company shall deliver to the Participant one share of Company Common Stock (or the value thereof) in settlement of each Restricted Stock Unit that has become earned and vested as provided in Section 2 on the first to occur of the following: (i) on or as soon as practicable following the date of the Administrator Certification (but in no event later than 2½ months after the Vesting Date); (ii) in the event of a termination of employment or service due to death, as soon as practicable following the Participant’s termination of employment or service by reason of death; (iii) in the event of a Qualifying CIC Termination, within thirty (30) days following the effective date of the Participant’s Qualifying CIC Termination, in each case (A) in Company Common Stock by either, (x) issuing one or more certificates evidencing the Company Common Stock to the Participant or (y) registering the issuance of the Stock in the name of the Participant through a book entry credit in the records of the Company’s transfer agent, or (B) in the event of settlement upon a Change in Control, a cash payment equal to the Change in Control Price, multiplied by the number of vested Restricted Stock Units. No fractional shares of Company Common Stock shall be issued in settlement of Restricted Stock Units. Fractional Restricted Stock Units shall be settled through a cash payment equal to the Fair Market Value of the Company Common Stock on the settlement date.

4.Securities Law Compliance. Notwithstanding any other provision of this Agreement, the Participant may not sell the shares of Company Common Stock acquired upon vesting of the Restricted Stock Units unless such shares are registered under the Securities Act of 1933, as amended (the “Securities Act”), or, if such shares are not then so registered, such sale would be exempt from the registration requirements of the Securities Act. The sale of such

shares must also comply with other applicable laws and regulations governing the shares and Participant may not sell the shares of Company Common Stock if the Company determines that such sale would not be in material compliance with such laws and regulations.

5.Participant’s Rights with Respect to the Restricted Stock Units.

(a)Restrictions on Transferability. The Restricted Stock Units granted hereby are not assignable or transferable, in whole or in part, and may not, directly or indirectly, be offered, transferred, sold, pledged, assigned, alienated, hypothecated or otherwise disposed of or encumbered (including without limitation by gift, operation of law or otherwise) other than by will or by the laws of descent and distribution to the estate of the Participant upon the Participant’s death; provided that the deceased Participant’s beneficiary or representative of the Participant’s estate shall acknowledge and agree in writing, in a form reasonably acceptable to the Company, to be bound by the provisions of this Agreement and the Plan as if such beneficiary or the estate were the Participant.

(b)No Rights as Stockholder. The Participant shall not have any rights as a stockholder including any voting, dividend or other rights or privileges as a stockholder of the Company with respect to any Company Common Stock corresponding to the Restricted Stock Units granted hereby unless and until shares of Company Common Stock are issued to the Participant in respect thereof.

(c)Dividend Equivalents. If the Company declares a cash dividend on the shares of Company Common Stock, then the Participant shall be credited with Dividend Equivalents in the form of a right to a cash payment equal to (i) the amount of the dividend declared and paid for each share of Company Common Stock, multiplied by (ii) (x) the number of Restricted Stock Units earned by the Participant as determined by the Administrator pursuant to Section 3(a) or (y) in the case of a termination of employment or service by reason of Death or a Qualifying CIC Termination, the number of Restricted Stock Units equal to the Target Award. Dividend Equivalents shall be subject to the same forfeiture restrictions as the Restricted Stock Units to which they are attributable and shall be paid on the same date the Restricted Stock Units to which they are attributable are settled in accordance with Section 3 hereof. Dividend Equivalents credited to a Participant shall be distributed in cash or, at the discretion of the Administrator, in shares of Company Common Stock having a Fair Market Value equal to the amount of the Dividend Equivalents, if any.

6.Participant’s Representations, Warranties and Covenants.

(a)No Conflicts; No Consents. The execution and delivery by Participant of this Agreement, the consummation of the transactions contemplated hereby and the performance of Participant’s obligations hereunder do not and will not (i) materially conflict with or result in a material violation or breach of any term or provision of any Law applicable to either Participant or the Restricted Stock Units or (ii) violate in any material respect, conflict with in any material respect or result in any material breach of, or constitute (with or without notice or lapse of time or both) a material default under, or require either Participant to obtain any consent, approval or action of, make any filing with or give any notice to any Person as a result or under the terms of,

any contract, agreement, instrument, commitment, arrangement or understanding to which Participant is a party.

(b)Compliance with Rule 144. If any shares of Company Common Stock issued in respect of the Restricted Stock Units are to be disposed of in accordance with Rule 144, the Participant shall transmit to the Company an executed copy of Form 144 (if required by Rule 144) no later than the time such form is required to be transmitted to the Commission for filing and such other documentation as the Company may reasonably require to assure compliance with Rule 144 in connection with such disposition.

(c)Participant Status. The Participant represents and warrants that, as of the date hereof, the Participant is an officer, employee, director or Consultant of the Company or a Subsidiary.

7.Adjustment in Capitalization. The number, class or other terms of any outstanding Restricted Stock Units shall be adjusted by the Committee to reflect any stock dividend, stock split or share combination or any recapitalization, business combination, merger, consolidation, spin-off, exchange of shares, liquidation or dissolution of the Company or other similar transaction affecting the Company Common Stock in such manner as it determines in its sole discretion.

8.Miscellaneous.

(a)Binding Effect; Benefits. This Agreement shall be binding upon and inure to the benefit of the parties to this Agreement and their respective successors and assigns. Nothing in this Agreement, express or implied, is intended or shall be construed to give any person other than the parties to this Agreement or their respective successors or assigns any legal or equitable right, remedy or claim under or in respect of any agreement or any provision contained herein.

(b)No Right to Continued Employment. Nothing in the Plan or this Agreement shall interfere with or limit in any way the right of the Company or any of its Subsidiaries to terminate the Participant’s employment at any time, or confer upon the Participant any right to continue in the employ of the Company or any of its Subsidiaries.

(c)Interpretation. This Agreement is subject to the terms and conditions of the Plan. In the event of any inconsistency between the provisions of this Agreement and the Plan, the Plan shall govern. The Administrator, acting pursuant to the Plan, as constituted from time to time, shall, except as expressly provided otherwise herein, have the right to determine reasonably and in good faith any questions that arise in connection with this Agreement, and any such determination shall be final, binding and conclusive on all Participants and other individuals claiming any right under the Plan. The failure of the Company or the Participant to insist upon strict performance of any provision hereunder, irrespective of the length of time for which such failure continues, shall not be deemed a waiver of such party’s right to demand strict performance at any time in the future. No consent or waiver, express or implied, to or of any breach or default in the performance of any obligation or provision hereunder shall constitute a

consent or waiver to or of any other breach or default in the performance of the same or any other obligation hereunder.

(d)Tax Withholding. Whenever any cash or other payment is to be made hereunder or with respect to the Restricted Stock Units, the Company or any Subsidiary shall have the power to withhold an amount (in cash, Restricted Stock Units or in Company Common Stock issuable upon settlement of Restricted Stock Units or from other amounts paid to the Participant in cash (whether under the Plan or otherwise)) sufficient to satisfy federal, state, and local withholding tax requirements relating to such transaction. The Company may require the recipient of shares of Company Common Stock to remit to the Company an amount in cash sufficient to satisfy the amount of taxes required to be withheld as a condition to the issuance of shares in settlement of the Restricted Stock Units. The Committee may, in its discretion, require the Participant, or permit the Participant to elect, subject to such conditions as the Committee shall impose, to meet such obligations by having the Company withhold or sell the least number of whole shares of Company Common Stock having a Fair Market Value sufficient to satisfy all or part of the amount required to be withheld. The Company or such Subsidiary may defer the settlement of Restricted Stock Units until such withholding or other tax requirements are satisfied and if the Participant has not satisfied such withholding or other tax requirements as of the last day of the calendar year in which the Vesting Date occurs, the Restricted Stock Units shall be forfeited. The Participant shall be responsible for all withholding taxes and other tax consequences of this award of Restricted Stock Units.

(e)Applicable Law. The Participant acknowledges that the Company is organized under the laws of the State of Delaware, U.S.A. The Participant and the Company agree that this Agreement shall be construed in accordance with and governed by the laws of the State of Delaware, U.S.A., without reference to principles of conflict of laws that would apply the laws of any other jurisdiction.

(f)Forum Selection. The Participant acknowledges that the Company’s principal place of business is in, and a substantial portion of the Company’s business is based out of, the Commonwealth of Virginia, U.S.A. The Participant also acknowledges that, as such, during the course of the Participant’s service with the Company and its Subsidiaries, the Participant shall have substantial contacts with the Commonwealth of Virginia, U.S.A. Accordingly, the Participant and the Company agree that the exclusive forum for any action, demand, claim or counterclaim relating to the terms and provisions of this Agreement, or to their breach, shall be in the appropriate state or federal court located in the Commonwealth of Virginia, U.S.A. The Participant and the Company hereby consent to the personal jurisdiction of such courts over the parties to this Agreement. The Participant expressly waives any defense that such courts lack personal jurisdiction or are inconvenient. The Participant and the Company further agree that in any such action for breach or enforcement of this Agreement, no party will seek to challenge the validity or enforceability of any part of this Agreement.

(g)Amendment. This Agreement may not be amended, modified or supplemented orally, but only by a written instrument executed by the Participant and the Company.

(h)Assignability. Neither this Agreement nor any right, remedy, obligation or liability arising hereunder or by reason hereof shall be assignable by the Company or the Participant without the prior written consent of the other party, provided that the Company may assign all or any portion of its rights or obligations under this Agreement to one or more persons or other entities designated by it.

(i)Severability; Blue Pencil. In the event that any one or more of the provisions of this Agreement shall be or become invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not be affected thereby.

(j)Limitation on Rights; No Right to Future Grants; Extraordinary Item of Compensation. By entering into this Agreement and accepting the Restricted Stock Units evidenced hereby, the Participant acknowledges: (a) that the Plan is discretionary in nature and may be suspended or terminated by the Company at any time; (b) that the Award does not create any contractual or other right to receive future grants of Awards; (c) that participation in the Plan is voluntary; (d) that the value of the Restricted Stock Units is not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments; and (e) that the future value of the Company Common Stock is unknown and cannot be predicted with certainty.

(k)Employee Data Privacy. The collection, use, disclosure and transfer, in electronic or other form, of personally identifiable information to facilitate the grant of the Award and the administration of the Plan by and among, as applicable, the Company and the Participant’s employer, if different, any of the Company’s affiliates, any agent of the Company administering or providing Plan services is governed by the Employee Privacy Notice (the “Privacy Notice”) that Participant received in the course of his or her relationship with Company. The Participant understands that he or she may review the Privacy Notice or contact his or her local human resources representative to request a copy of the Privacy Notice. Please contact ethics@bah.com if you have any questions or concerns about how the Company or its subsidiaries and affiliates process personally identifiable information.

(l)Consent to Electronic Delivery. By entering into this Agreement and accepting the Restricted Stock Units evidenced hereby, Participant hereby consents to the delivery of information (including, without limitation, information required to be delivered to the Participant pursuant to applicable securities laws) regarding the Company and the Subsidiaries, the Plan, this Agreement and the Restricted Stock Units via Company website, the Fidelity NetBenefits website or any other online access system of the Company’s third party Plan administrator, email or other electronic delivery.

(m)Section 409A of the Code. This Agreement is intended to be administered in a manner consistent with the requirements, where applicable, of Section 409A of the Code and the regulations promulgated thereunder (“Section 409A”). Where reasonably practicable, the Agreement shall be administered in a manner to avoid the imposition on the Participant of immediate tax recognition and additional taxes pursuant to Section 409A. In addition, to the

extent permissible under Section 409A, any series of installment payments under this Agreement shall be treated as a right to a series of separate payments. Notwithstanding the foregoing, the Company shall not have any liability to any Person in the event Section 409A applies to any payment hereunder in a manner that results in adverse tax consequences to the Participant or any of the Participant’s beneficiaries.

(n)Specified Employee Delay. If the Participant is deemed a “specified employee” within the meaning of Section 409A, as determined by the Committee, at a time when the Participant becomes eligible for settlement of the Restricted Stock Units upon his or her “separation from service” within the meaning of Section 409A, then to the extent necessary to prevent any accelerated or additional tax under Section 409A, such settlement will be delayed until the earlier of: (a) the date that is six months following the Participant’s termination of service and (b) the Participant’s death. Notwithstanding anything to the contrary in this Agreement, if settlement is to occur upon a termination of service other than due to death or Disability and the Participant is a specified employee, to the extent necessary to comply with, and avoid imposition on the Participant of any additional tax or interest imposed under, Section 409A, settlement shall instead occur on the first business day following the six-month anniversary of the Participant’s termination of service (or, if earlier, upon the Participant’s death), or as soon thereafter as practicable (but no later than 90 days thereafter).

(o)Headings and Captions. The section and other headings contained in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

(p)Notices. All notices under this Agreement shall be (i) delivered by hand, (ii) sent by commercial overnight courier service, (iii) sent by registered or certified mail, return receipt requested, and first-class postage prepaid, (iv) sent by e-mail or any other form of electronic transfer or delivery approved by the Administrator, or (v) faxed, in each case to the parties at their respective addresses and facsimile numbers set forth in the records of the Company or at such other address or facsimile number as may be designated in a notice by either party to the other.

(q)Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original and all of which together shall constitute one and the same instrument.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP, and the rules and regulations of the U.S. Securities and Exchange Commission, or SEC. All intercompany balances and transactions have been eliminated in consolidation.

The consolidated financial statements and notes of the Company include its subsidiaries, and the joint ventures and partnerships over which the Company has a controlling financial interest. The Company uses the equity method to account for investments in entities that it does not control if it is otherwise able to exert significant influence over the entities' operating and financial policies.

The Company’s fiscal year ends on March 31 and unless otherwise noted, references to fiscal year or fiscal are for fiscal years ended March 31. The accompanying consolidated financial statements present the financial position of the Company as of March 31, 2019 and 2018 and the Company’s results of operations for fiscal 2019, fiscal 2018, and fiscal 2017.

Certain amounts reported in the Company's prior year consolidated financial statements have been reclassified to conform to the current year presentation. Effective April 1, 2018, the Company adopted Accounting Standards Codification (ASC) No. 606, Revenue from Contracts with Customers (Topic 606), and Accounting Standard Updates (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, on a full retrospective method for amounts and percentages presented and disclosures set forth in this Form 10-K for fiscal 2019, 2018, and 2017.

Accounting Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Areas of the consolidated financial statements where estimates may have the most significant effect include contractual and regulatory reserves, valuation and lives of tangible and intangible assets, contingent consideration related to business acquisitions, impairment of long-lived assets, accrued liabilities, revenue recognition, including the accrual of indirect costs, bonus and other incentive compensation, stock-based compensation, reserves for tax benefits and valuation allowances on deferred tax assets, provisions for income taxes, postretirement obligations, certain deferred costs, collectability of receivables, and loss accruals for litigation. Actual results experienced by the Company may differ materially from management's estimates.

Revenue Recognition

The Company's revenues from contracts with customers (clients) are derived from offerings that include consulting, analytics, digital solutions, engineering, and cyber services, substantially with the U.S. government and its agencies, and to a lesser extent, subcontractors. The Company also serves foreign governments, as well as domestic and international commercial clients. The Company performs under various types of contracts, which include cost-reimbursable-plus-fee contracts, time-and-material contracts, and fixed-price contracts.

The Company considers a contract with a customer to exist under Topic 606, when there is approval and commitment from both the Company and the customer, the rights of the parties and payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. The Company also will consider whether two or more contracts entered into with the same customer should be combined and accounted for as a single contract. Furthermore, in certain transactions with commercial clients and with the U.S. government, the Company may commence providing services prior to receiving a formal approval from the customer. In these situations, the Company will consider the factors noted above, the risks associated with commencing the work and legal enforceability in determining whether a contract with the customer exists under Topic 606.

Customer contracts are often modified to change the scope, price, specifications or other terms within the existing arrangement. Contract modifications are evaluated by management to determine whether the modification should be accounted for as part of the original performance obligation(s) or as a separate contract. If the modification adds distinct goods or services and increases the contract value proportionate to the stand-alone selling price of the additional goods or services, it will be accounted for as a separate contract. Generally, the Company’s contract modifications do not include goods or services which are distinct, and therefore are accounted for as part of the original performance obligation(s) with any impact on transaction price or estimated costs at completion being recorded as through a cumulative catch-up adjustment to revenue.

The Company evaluates each service deliverable contracted with the customer to determine whether it represents promises to transfer distinct goods or services. Under Topic 606, these are referred to as performance obligations. One or more service deliverables often represent a single performance obligation. This evaluation requires significant judgment and the impact of combining or separating performance obligations may change the time over which revenue from the contract is recognized. The Company’s contracts generally provide a set of integrated or highly interrelated tasks or services and are therefore accounted for as a single performance obligation. However, in cases where we provide more than one distinct good or service within a customer contract, the contract is separated into individual performance obligations which are accounted for discretely.

Contracts with the U.S. government are subject to the Federal Acquisition Regulation ("FAR") and are priced based on estimated or actual costs of providing the goods or services. The Company derives a majority of its revenue from contracts awarded through a competitive bidding process. Pricing for non-U.S. government agencies and commercial customers is based on discrete negotiations with each customer. Certain of the Company’s contracts contain award fees, incentive fees or other provisions that may increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and may be based upon customer discretion. Management estimates variable consideration as the most likely amount that we expect to achieve based on our assessment of the variable fee provisions within the contract, prior experience with similar contracts or clients, and management’s evaluation of the performance on such contracts. The Company may perform work under a contract that has not been fully funded if the work has been authorized by the management and the customer to proceed. The Company evaluates unfunded amounts as variable consideration in estimating the transaction price. We include the estimated variable consideration in our transaction price to the extent that it is probable that a significant reversal of revenue will not occur upon the ultimate settlement of the variable fee provision. In the limited number of situations where our contracts with customers contain more than one performance obligation, the Company allocates the transaction price of a contract between the performance obligations in the proportion to their respective stand-alone selling prices. The Company generally estimates the stand-alone selling price of performance obligations based on an expected cost-plus margin approach as allowed under Topic 606. Our U.S. government contracts generally contain FAR provisions that enable the customer to terminate a contract for default or for the convenience of the U.S. government.

The Company recognizes revenue for each performance obligation identified within our customer contracts when, or as, the performance obligation is satisfied by transferring the promised goods or services. Revenue may either be recognized over time, or at a point in time. The Company generally recognizes revenue over time as our contracts typically involve a continuous transfer of control to the customer. A continuous transfer of control under contracts with the U.S. government and its agencies is evidenced by clauses which require the Company to be paid for costs incurred plus a reasonable margin in the event that the customer unilaterally terminates the contract for convenience. For contracts where the Company recognizes revenue over time, a contract cost-based input method is generally used to measure progress towards satisfaction of the underlying performance obligation(s). Contract costs include direct costs such as materials, labor and subcontract costs, as well as indirect costs identifiable with, or allocable to, a specific contract that are expensed as incurred. The Company does not incur material incremental costs to acquire or fulfill contracts. Under a contract cost-based input method, revenue is recognized based on the proportion of contract costs incurred to the total estimated costs expected to be incurred upon completion of the underlying performance obligation. The Company includes generally both funded and unfunded portions of customer contracts in this estimation process.

For interim financial reporting periods, contract revenue attributable to indirect costs is recognized based upon agreed-upon annual forward-pricing rates established with the U.S. government at the start of each fiscal year. Forward pricing rates are estimated and agreed upon between the Company and the U.S. government and represent indirect contract costs required to execute and administer contract obligations. The impact of any agreed-upon changes, or changes in the estimated annual forward-pricing rates, will be recorded in the interim financial reporting period when such changes are identified. This change relates to the interim financial reporting period differences between the actual indirect cost incurred and allocated to customer contracts compared to the estimated amounts allocated to contracts using the estimated annual forward-pricing rates established with the U.S. government.

On certain contracts, principally time-and-materials and cost-reimbursable-plus-fee contracts, revenue is recognized using the right-to-invoice practical expedient as the Company is contractually able to invoice the customer based on the control transferred. However, we did not elect to use the practical expedient which would allow the Company to exclude contracts recognized using the right-to-invoice practical expedient from the remaining performance obligations disclosed below. Additionally, for stand-ready performance obligations to provide services under fixed-price contracts, revenue is recognized over time using a straight-line measure of progress as the control of the services is provided to the customer ratably over the term of the contract. If a contract does not meet the criteria for recognition of revenue over time, we recognize revenue at the point in time when control of the good or service is transferred to the customer. Determining a measure of progress towards the satisfaction of performance obligations requires management to make judgments that may affect the timing of revenue recognition.

In addition to the right-to-invoice practical expedient discussed above, the Company applied certain other practical expedients permitted by Topic 606, which include: a) using the portfolio approach where contracts with similar characteristics were assessed collectively to evaluate risk of being impacted by the adoption of Topic 606; b) applying the practical expedient allowing the Company to not restate completed contracts which began and ended in the same fiscal year prior to the date of the initial adoption; and c) electing to omit the disclosure related to remaining performance obligations for reporting periods presented before the date of the initial adoption.

Many of our contracts recognize revenue under a contract cost-based input method and require an Estimate-at-Completion (EAC) process, which management uses to review and monitor the progress towards the completion of our performance obligations. Under this process, management considers various inputs and assumptions related to the EAC, including, but not limited to, progress towards completion, labor costs and productivity, material and subcontractor costs, and identified risks. Estimating the total cost at completion of performance obligations is subjective and requires management to make assumptions about future activity and cost drivers under the contract. Changes in these estimates can occur for a variety of reasons and, if significant, may impact the profitability of the Company’s contracts. Changes in estimates related to contracts accounted for under the EAC process are recognized in the period when such changes are made on a cumulative catch-up basis. If the estimate of contract profitability indicates an anticipated loss on a contract, the Company recognizes the total loss at the time it is identified. For fiscal years ended March 31, 2019, 2018 and 2017, the aggregate impact of adjustments in contract estimates was not material.

Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations do not include negotiated but unexercised options or the unfunded value of expired contracts.

Cash and Cash Equivalents

Cash and cash equivalents include operating cash on hand and highly liquid investments having a weighted average maturity of 60 days or less and a weighted average life of 120 days or less. The Company’s cash equivalents consist primarily of government money market funds and money market deposit accounts. The Company maintains its cash and cash equivalents in bank accounts that, at times, exceed the federally insured FDIC limits. The Company has not experienced any losses in such accounts.

Valuation of Accounts Receivable

The Company maintains allowances for doubtful accounts against certain billed and unbilled receivables based upon the latest information regarding whether specific charges are recoverable or invoices are ultimately collectible. Assessing the recoverability of charges and collectability of customer receivables requires management judgment. The Company determines its allowance for doubtful accounts by specifically analyzing individual accounts receivable, historical bad debts, customer credit-worthiness, current economic conditions, accounts receivable aging trends for billed receivables, availability of funding, compliance with contractual terms and conditions, client satisfaction with work performed, and other factors impacting unbilled receivables. Valuation reserves are periodically re-evaluated and adjusted as more information about the ultimate recoverability and collectability of accounts receivable becomes available. Upon determination that a receivable is uncollectible, the receivable balance and any associated reserve are written off.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents and accounts receivable. The Company’s cash equivalents are generally invested in U.S. government money market funds and money market deposit accounts. The Company believes that credit risk for accounts receivable is limited as the receivables are primarily with the U.S. government.

Property and Equipment

Property and equipment are recorded at cost, and the balances are presented net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. Furniture and equipment is depreciated over five to ten years, and computer equipment is depreciated over four years. Leasehold improvements are amortized over the shorter of the useful life of the asset or the lease term. Maintenance and repairs are charged to expense as incurred.

Rent expense is recorded on a straight-line basis over the life of the respective lease. The difference between the cash payment and rent expense is recorded as deferred rent in either accounts payable and other accrued expenses or other long-term liabilities in the consolidated balance sheets, depending on when the amounts will be recognized. The Company receives incentives for tenant improvements on certain of its leases. The cash expended on such improvements is recorded as property and equipment and amortized over the life of the associated asset, or lease term, whichever is shorter. Incentives for tenant improvements are recorded as deferred rent in either accounts payable and other accrued expenses or other long-term liabilities in the consolidated balance sheets depending on when the amounts will be recognized. Incentives for tenant improvements are amortized on a straight-line basis over the lease term

Business Combinations

The accounting for the Company’s 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. The Company has 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.

We have a contingent consideration arrangement in connection with a business acquisition which requires a fair value measurement determined using probability-weighted cash flows. See Note 20 to our consolidated financial statements for further information about the valuation of the contingent consideration liability and the inputs used in the fair value measurement.

Intangible Assets

Intangible assets primarily consist of the Company's trade name, customer relationships, software and other amortizable intangible assets. The Company capitalizes the following costs associated with developing internal-use computer software pertaining to upgrades in our business and financial systems: (i) external direct costs of materials and services consumed in developing or obtaining internal-use computer software and (ii) certain payroll and payroll-related costs for Company employees who are directly associated with the development of internal-use software, to the extent of the time spent directly on the project. Customer relationships are generally amortized on an accelerated basis over the expected life based on projected future cash flows of approximately three to twelve years. Software purchased or developed for internal use is amortized over three to six years. The Company's trade name is not amortized, but is tested for impairment on at least an annual basis as of January 1 and more frequently if interim indicators of impairment exist. The trade name is considered to be impaired if the carrying value exceeds its estimated fair value. The Company used the relief from royalty method to estimate the fair value. The fair value of the asset is the present value of the license fees avoided by owning the asset, or the royalty savings. During the fiscal year ended March 31, 2017, the Company recorded impairment charges related to intangible assets acquired in an acquisition. During the fiscal years ended March 31, 2019 and March 31, 2018, the Company did not record any impairment of intangible assets.

Goodwill

The Company assesses goodwill for impairment on at least an annual basis on January 1 unless interim indicators of impairment exist. Goodwill is considered to be impaired when the net book value of a reporting unit exceeds its estimated fair value. The Company operates as a single operating segment and as a single reporting unit for the purpose of evaluating goodwill. As of January 1, 2019, the Company performed its annual impairment test of goodwill by comparing the fair value of the Company (based on market capitalization) to the carrying value of the Company's net equity, and concluded that the fair value of the reporting unit was significantly greater than the carrying amount. During the fiscal years ended March 31, 2019, 2018, and 2017, the Company did not record any impairment of goodwill.

Long-Lived Assets

The Company reviews its long-lived assets, including property and equipment and amortizable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. If the total of the expected undiscounted future net cash flows is less than the carrying amount of the asset, a loss is recognized for any excess of the carrying amount over the fair value of the asset. During the fiscal years ended March 31, 2019, 2018, and 2017, the Company did not record any material impairment charges.

Income Taxes

The Company provides for income taxes as a “C” corporation on income earned from operations. The Company is subject to federal, state, and foreign taxation in various jurisdictions.

Deferred tax assets and liabilities are recorded to recognize the expected future tax benefits or costs of events that have been, or will be, reported in different years for financial statement purposes than for tax purposes. Deferred tax assets and liabilities are computed based on the difference between the consolidated financial statement carrying amount and tax basis of assets and liabilities using enacted tax rates and laws for the years in which these items are expected to reverse. If management determines that some portion or all of a deferred tax asset is not “more likely than not” to be realized, a valuation allowance is recorded as a component of the income tax provision to reduce the deferred tax asset to an appropriate level in that period. In determining the need for a valuation allowance, management considers all positive and negative evidence, including historical earnings, projected future taxable income, future reversals of existing taxable temporary differences, taxable income in prior carryback periods, and prudent, feasible tax-planning strategies.

The Company periodically assesses its tax positions for all periods open to examination by tax authorities based on the latest available information. Where it is not more likely than not that the Company’s tax position will be sustained, the Company records its best estimate of the resulting tax liability, penalties, and interest in the consolidated financial statements. These uncertain tax positions are recorded as a component of income tax expense. As uncertain tax positions in periods open to examination are closed out, or as new information becomes available, the resulting change is reflected in the recorded liability and income tax expense. Penalties and interest recognized related to the reserves for uncertain tax positions are recorded as a component of income tax expense.

See Note 14 to our consolidated financial statements for further information regarding the effects of U.S. tax law changes enacted during the third fiscal quarter of 2018 and financial reporting guidance issued by the SEC.

Comprehensive Income

Comprehensive income is the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, and is presented in the consolidated statements of comprehensive income. Accumulated other comprehensive loss as of March 31, 2019 and 2018 consisted of net unrealized losses on the Company’s defined and postretirement benefit plans and unrealized gains or losses on interest rate swaps designated as cash flow hedges.

Share-Based Payments

Share-based payments to employees are recognized in the consolidated statements of operations based on their grant date fair values with the expense for time vested awards recognized on an accelerated basis over the vesting period. The expense for performance awards is recognized straight line over the vesting period. The Company uses the Black-Scholes option-pricing model to determine the fair value of its option awards at the time of grant.

Defined Benefit Plan and Other Postretirement Benefits

The Company recognizes the underfunded status of defined benefit plans on the consolidated balance sheets within other long-term liabilities. Gains and losses, and prior service costs and credits that have not yet been recognized through net periodic benefit cost are recognized in accumulated other comprehensive income (loss), net of tax effects, and will be amortized as a component of net periodic cost in future periods. The measurement date, the date at which the benefit obligations are measured, is the Company’s fiscal year-end.

The Company also offers medical and dental benefits to inactive employees (and their eligible dependents) on long-term disability. The Company accrues the costs of the benefits at the date the inactive employee becomes disability eligible and elects to participate in the benefit. The accrued cost for such benefits is calculated using an actuarial estimate of the present value of all future benefit payments for obligations at the end of the fiscal year.

Self-Funded Medical Plans

The Company maintains self-funded medical insurance. Self-funded plans include Consumer Driven Health Plans with a Health Savings Account option and traditional choice plans. Further, self-funded plans also include prescription drug and dental benefits. The Company records an incurred but unreported claim liability in the accrued compensation and benefits line of the consolidated balance sheets for self-funded plans based on an actuarial valuation. The estimate of the incurred but unreported claim liability was provided by a third-party valuation firm, primarily based on claims and participant data for the medical, dental, and pharmacy related costs.

Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, we consider the principal or most advantageous market in which the asset or liability would transact, and if necessary, consider assumptions that market participants would use when pricing the asset or liability.

The accounting guidance for fair value measurements establishes a three-level fair value hierarchy that prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3). Assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. See Note 20 to our consolidated financial statements for additional information on the Company’s fair value measurements.

Recently Adopted Accounting Standards

In March 2019, the SEC issued its Final Rule Release No. 33-10618, FAST Act Modernization and Simplification of Regulation S-K. The guidance in this Release revises certain disclosure requirements in SEC Regulation S-K, with the intent of improving the readability of filed documents and simplifying registrants' compliance efforts. The Company adopted certain aspects of this Release in the fourth quarter of fiscal 2019 which did not have a material impact on the consolidated financial statements. Other aspects not yet adopted are still being evaluated but are not expected to be material.

The Company completed its assessment for the tax effects of the Tax Cuts and Jobs Act, or the 2017 Tax Act, under the guidance of Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, or SAB 118, during the third quarter of fiscal 2019. The Company recorded adjustments to previously recognized provisional estimates primarily related to the re-measurement effects on certain deferred tax balances. The completion of its assessment resulted in a reduction in the provision for income taxes during the third quarter of fiscal 2019. See Note 14 to the consolidated financial statements for further information regarding the impact of the 2017 Tax Act on fiscal 2019.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The amendments set forth certain presentation requirements, including that such analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed with all significant reconciling items described by appropriate captions with contributions from and distributions to owners shown separately. The amendments became effective on November 5, 2018 and did not have a material effect on the Company's consolidated financial statements for fiscal 2019. According to the SEC’s Questions and Answers of General Applicability Question 105.09 dated September 25, 2018 and updated October 4, 2018, the SEC would not object if the filer’s first presentation of the changes in stockholders’ equity is included in its Form 10-Q for the quarter that begins after the effective date of the amendments. The Company will first present such changes beginning with the first quarter of fiscal 2020.

In August 2018, the FASB issued ASU 2018-14, Compensation -Retirement Benefits -Defined Benefit Plans -General (Topic 715-20) - Disclosure Framework -Changes to the Disclosure Requirement for Defined Benefit Plans. This guidance is designed to improve the effectiveness of disclosures by removing and adding disclosures related to defined benefit plans. ASU 2018-14 is effective for reporting periods beginning after December 15, 2020 with early adoption permitted. In the fourth quarter of fiscal 2019 the Company early adopted this standard and adoption of this standard did not have a material impact on the consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. This guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Additionally, the guidance also expands an entity's ability to apply hedge accounting for nonfinancial and financial risk components, simplifies the hedge documentation and hedge effectiveness assessment requirements, and modifies certain disclosure requirements. ASU 2017-12 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. In the fourth quarter of fiscal 2019 the Company early adopted this standard using the modified retrospective approach. The adoption of this standard did not have a material impact on the consolidated financial statements.

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Codification No. 606, Revenue from Contracts with Customers (Topic 606). Topic 606, as amended, replaced existing revenue recognition standards by outlining a single set of comprehensive principles for recognizing revenue. The revenue standard also significantly expanded the disclosure requirements for revenue arrangements. Amendments to Topic 606 have generally focused on promoting a more consistent interpretation and application of the principles for recognizing revenue.

Topic 606 was effective for the Company beginning on April 1, 2018 (i.e., beginning with the first quarter fiscal 2019 interim financial statements). The Company adopted the new revenue standard using the full retrospective transition method, which requires that it be applied to each prior reporting period presented and that the cumulative effect of applying the standard be recognized at the earliest period presented (i.e., April 1, 2016, the beginning of the first quarter of fiscal 2017). During fiscal 2018, the Company completed its assessment of the cumulative effect of adopting Topic 606 and assessed the impact to be immaterial as of the date of adoption. The cumulative impact on our retained earnings for the earliest period presented of April 1, 2016 was an increase of $2.9 million. Thereafter, the adoption of Topic 606 increased our fiscal 2017 retained earnings by $8.4 million and decreased our fiscal 2018 retained earnings by $3.4 million, resulting in a cumulative impact on our retained earnings of$7.9 million as of April 1, 2018. The impact of Topic 606 on fiscal 2017 and 2018 results may not be representative of the impact on subsequent years’ results.

The Company also retrospectively adopted ASU 2017-07, which changed the presentation of net periodic benefit cost components on the condensed consolidated statement of operations. Under this guidance, the service cost component of net periodic benefit cost continues to be presented consistent with other employee compensation costs and within operating income, while the remaining components of net periodic benefit costs are excluded from operating income. As a result, net periodic benefit costs related to non-service components were reclassified to Other income (expense), net in the consolidated statement of operations for fiscal 2018 and 2017. See adoption impacts of ASU 2017-07 in the table below.

The Company's previously issued consolidated financial statements have been adjusted for the retrospective adoption of both Topic 606 and ASU 2017-07, as summarized in the following table:

	Fiscal Year Ended March 31, 2018								Fiscal Year Ended March 31, 2017

Recent Accounting Pronouncements Not Yet Adopted

In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This guidance requires a customer in a cloud computing arrangement that is a service contract to follow existing internal-use software guidance to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 generally aligns the guidance on capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with that of implementation costs incurred to develop or obtain internal-use software, including hosting arrangements that include an internal-use software license. ASU 2018-15 is effective for interim reporting periods for fiscal years beginning after December 15, 2019. Early adoption is permitted. The standard may be adopted either retrospectively or prospectively. The Company is currently assessing the future impact of this update on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability of accounting for lease transactions. The new leasing standard requires lessees to recognize lease assets and lease liabilities on their balance sheet for all leases with a lease term of greater than 12 months. Lessor accounting is largely unchanged. Topic 842 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB provided an alternative transition method of adoption through ASU No. 2018-11, Targeted Improvements, which permits the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption. The Company will adopt the standard beginning in fiscal 2020 using the modified retrospective transition approach, specifically, using the alternative transition method provided by ASU 2018-11.

A dedicated implementation team has substantially completed its evaluation of the impact of the new standard. The Company's assessment efforts to date have included reviewing the provisions of Topic 842, gathering information to evaluate its lease population and portfolio, evaluating the nature of real and personal property and other arrangements that may meet the definition of a lease, designing and implementing one-time implementation controls as well as new post-adoption lease processes and controls, implementing a new lease accounting software solution, and evaluating certain accounting policy elections. As a result of our evaluation, the Company identified changes to and modified certain of our accounting policies and practices. While some modifications were complex to design and test, the effect of such changes are not expected to be significant upon adoption of Topic 842. The Company will elect certain practical expedients provided under Topic 842, including the option not to apply lease recognition for short–term leases; an election to not separate lease from non-lease components; and a package of practical expedients such that, upon the initial adoption of Topic 842, the Company will not reassess whether expired or existing contracts contain leases, nor will the Company reassess the lease classification for expired or existing leases.

The Company expects that upon adoption it will recognize a material right-of-use asset of approximately $270 million and a lease liability of approximately $330 million on the balance sheet, which is inclusive of required conforming balance sheet reclassifications. The Company does not expect the standard to have any other material impact on the consolidated financial statements or results of operations. Adoption of the standard is not expected to impact the Company’s ability to comply with the financial covenants as defined in the Credit Agreement discussed further in Note 12. The Company is continuing to refine its processes in order to meet the accounting and disclosure requirements upon adoption of Topic 842 in the first quarter of fiscal2020.

Other recent accounting pronouncements issued during fiscal 2019 and through the filing date are not expected to have a material impact on the Company's present or historical consolidated financial statements.

Revenue from Contract with Customer [Abstract]

Revenue

REVENUE

The Company's revenues from contracts with customers (clients) are derived from offerings that include consulting, analytics, digital solutions, engineering, and cyber services, substantially with the U.S. government and its agencies, and to a lesser extent, subcontractors. The Company also serves foreign governments, as well as domestic and international commercial clients. The Company performs under various types of contracts, which include cost-reimbursable-plus-fee contracts, time-and-material contracts, and fixed-price contracts.

Disaggregation of Revenue

We disaggregate our revenue from contracts with customers by contract type, customer, as well as whether the Company acts as prime contractor or sub-contractor, as we believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. The following series of tables presents our revenue disaggregated by these categories.

Revenue by Contract Type:

We generate revenue under the following three basic types of contracts:

• Cost-Reimbursable Contracts: Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract, up to a ceiling based on the amount that has been funded, plus a fixed fee or award fee.

• Time-and-Materials Contracts: Under contracts in this category, we are paid a fixed hourly rate for each direct labor hour expended, and we are reimbursed for billable material costs and billable out-of-pocket expenses inclusive of allocable indirect costs. We assume the financial risk on time-and-materials contracts because our costs of performance may exceed negotiated hourly rates.

• Fixed-Price Contracts: Under a fixed-price contract, we agree to perform the specified work for a predetermined price. To the extent our actual direct and allocated indirect costs decrease or increase from the estimates upon which the price was negotiated, we will generate more or less profit, respectively, or could incur a loss.

The table below presents the total revenue for each type of contract:

	Fiscal Year Ended March 31,
	2019			2018			2017
Cost-reimbursable	$	3,580,595	53%	$	3,155,049	51%	$	2,882,178	50%
Time-and-materials	1,576,673		24%	1,542,899		25%	1,500,851		26%
Fixed-price	1,546,769		23%	1,469,652		24%	1,426,462		24%
Total Revenue	$	6,704,037	100%	$	6,167,600	100%	$	5,809,491	100%

Revenue by Customer Type:    

	Fiscal Year Ended March 31,
	2019			2018			2017

Civil Clients	1,760,996		26%	1,644,860		27%	1,611,309		28%
Total U.S. government	6,442,437		96%	5,969,451		97%	5,655,499		97%
Global Commercial Clients	261,600		4%	198,149		3%	153,992		3%
Total Revenue	$	6,704,037	100%	$	6,167,600	100%	$	5,809,491	100%

Revenue by Whether the Company Acts as a Prime Contractor or a Sub-Contractor:    

	Fiscal Year Ended March 31,
	2019			2018			2017
Prime Contractor	$	6,159,918	92%	$	5,626,544	91%	$	5,261,499	91%
Sub-contractor	544,119		8%	541,056		9%	547,992		9%
Total Revenue	$	6,704,037	100%	$	6,167,600	100%	$	5,809,491	100%

Performance Obligations

Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations do not include negotiated but unexercised options or the unfunded value of expired contracts.

As of March 31, 2019, the Company had $5.8 billion of remaining performance obligations and we expect to recognize more than half of the remaining performance obligations as revenue over the next 12 months, and approximately three quarters over the next 24 months. The remainder is expected to be recognized thereafter.

Contract Balances

As discussed in Note 2, the Company's performance obligations are typically satisfied over time and revenue is generally recognized using a cost-based input method. Fixed-price contracts are typically billed to the customer using milestone or fixed monthly payments, while cost-reimbursable-plus-fee and time-and-material contracts are typically billed to the customer at periodic intervals (e.g. monthly or weekly) as indicated by the terms of the contract. Disparities between the timing of revenue recognition and customer billings and cash collections results in net contract assets or liabilities being recognized at the end of each reporting period.

Contract assets primarily consist of unbilled receivables typically resulting from revenue recognized exceeding the amount billed to the customer and right to payment is not just subject to the passage of time. Contract liabilities primarily consist of advance payments, billings in excess of costs incurred and deferred revenue. Contract assets and liabilities are reported on a net contract basis at the end of each reporting period. The Company maintains an allowance for doubtful accounts to provide for an estimate of uncollected receivables. Refer to Note 7 for more information on receivables recognized from contracts accounted for under Topic 606.

The following table summarizes the contract balances recognized on the Company’s consolidated balance sheets:

	March 31, 2019		March 31, 2018
Contract assets:
Current	$	846,372	$	738,646
Long-term	61,391		59,633
Total	907,763		798,279
Contract liabilities:
Advance payments, billings in excess of costs incurred and deferred revenue	$	21,316	$	27,522

Changes in contract assets and contract liabilities are primarily due to the timing difference between the Company’s performance of services and payments from customers. For fiscal 2019, 2018 and 2017, we recognized revenue of $25.3 million, $16.2 million and $10.5 million, respectively, related to our contract liabilities on April 1, 2018, 2017 and 2016, respectively. To determine revenue recognized from contract liabilities during the reporting periods, the Company allocates revenue to individual contract liability balances and applies revenue recognized during the reporting periods first to the beginning balances of contract liabilities until the revenue exceeds the balances.

Earnings Per Share [Abstract]

Earnings Per Share

EARNINGS PER SHARE

The Company computes basic and diluted earnings per share amounts based on net income for the periods presented. The Company uses the weighted average number of common shares outstanding during the period to calculate basic earnings per share, or EPS. Diluted EPS adjusts the weighted average number of shares outstanding to include the dilutive effect of outstanding common stock options and other stock-based awards.

The Company currently has outstanding shares of Class A Common Stock. Unvested Class A Restricted Common Stock holders are entitled to participate in non-forfeitable dividends or other distributions. These unvested restricted shares participated in the Company's dividends declared and paid in each quarter of fiscal 2019, 2018, and 2017. As such, EPS is calculated using the two-class method whereby earnings are reduced by distributed earnings as well as any available undistributed earnings allocable to holders of unvested restricted shares. A reconciliation of the income used to compute basic and diluted EPS for the periods presented are as follows:

	Fiscal Year Ended March 31,
	2019		2018		2017
Earnings for basic computations (1)	$	416,664	$	299,824	$	258,495
Weighted-average Class A Common Stock outstanding	141,910,799		145,964,574		148,218,968
Total weighted-average common shares outstanding for basic computations	141,910,799		145,964,574		148,218,968
Earnings for diluted computations (1)	$	416,675	$	299,837	$	258,514
Dilutive stock options and restricted stock	1,245,377		1,785,448		2,055,672
Average number of common shares outstanding for diluted computations	143,156,176		147,750,022		150,274,640
Earnings per common share
Basic	$	2.94	$	2.05	$	1.74
Diluted	$	2.91	$	2.03	$	1.72

(1) During fiscal 2019, 2018, and 2017 approximately 0.6 million, 0.8 million, and 1.3 million shares of participating securities were paid dividends totaling $0.6 million, $0.8 million, and $0.9 million, respectively. For fiscal 2019, there were undistributed earnings of $1.2 million allocated to the participating class of securities in both basic and diluted earnings per share. For fiscal 2018, there were undistributed earnings of $1.1 million allocated to the participating class of securities in both basic and diluted earnings per share. For fiscal 2017, there were undistributed earnings of $1.4 million allocated to the participating class of securities in both basic and diluted earnings per share. The allocated undistributed earnings and the dividends paid comprise the difference between net income presented on the consolidated statements of operations and earnings for basic and diluted computations for fiscal 2019, 2018, and 2017.

The EPS calculation for fiscal 2019, 2018, and 2017 excludes 0.2 million, 0.3 million, and 0.05 million options, respectively, as their impact was anti-dilutive.

Acquisitions

ACQUISITIONS

There were no material acquisitions or dispositions during fiscal 2019 and 2018 or through the period subsequent to the issuance of the current financial statements.

Fiscal 2017 Acquisition

On January 24, 2017, the Company acquired eGov Holdings, Inc., which we refer to as Aquilent. As a result of the transaction, Aquilent became a wholly owned subsidiary of the Company. Aquilent is an architect of IT solutions for the U.S. Federal government. The acquisition further expands the Company's ability to blend its consulting heritage with advanced technical expertise.

The total purchase consideration paid at closing was $253.6 million. As part of the acquisition, the Company recorded the assets acquired and liabilities assumed at their acquisition date estimated fair value, with the difference between the fair value of the net assets acquired and the acquisition consideration reflected as goodwill. The following table represents the final allocation of fair value of assets acquired and liabilities assumed:

Current assets	$	15,809
Other tangible assets	1,144
Customer-relationship intangible assets	69,000
Goodwill	199,826
Current liabilities	(8,450		)
Tax liability	(13,554		)
Income tax uncertainty	(10,221		)
Total purchase consideration transfer at closing	$	253,554

The identifiable customer-relationship intangible assets of $69.0 million was valued using the excess earnings method discounted cash flow approach, incorporating Level 3 inputs as described under the fair value hierarchy of ASC 820 and it is being amortized over 12 years. An acquisition date tax of $13.6 million was relieved and paid during the first quarter of fiscal 2018. The Company continues to carry a related reserve of $10.2 million for income tax uncertainties created with the acquisition resulting from uncertainty in the sustainability of Aquilent's prior tax-return positions under examination with the relevant tax authorities. The goodwill of $199.8 million was primarily attributed to the specialized workforce and the expected synergies between the Company and Aquilent. The majority of the goodwill is expected to be deductible for tax purposes. Pro forma results of operations for this acquisition are not presented because it is not material to the Company's consolidated results.

Deferred Payment Obligation

DEFERRED PAYMENT OBLIGATION

Pursuant to an Agreement and Plan of Merger, or the Merger Agreement, dated as of May 15, 2008, and subsequently amended, The Carlyle Group indirectly acquired all of the issued and outstanding stock of the Company. In connection with this transaction, on July 31, 2008 the Company established a Deferred Payment Obligation, or DPO, of $158.0 million, payable 8.5 years after the Closing Date, or until settlement of all outstanding claims, less any settled claims. Pursuant to the Merger Agreement, $78.0 million of the $158.0 million DPO was required to be paid in full to the selling shareholders. On December 11, 2009, in connection with a recapitalization transaction, $100.4 million was paid to the selling shareholders, of which $78.0 million was the repayment of that portion of the DPO, with approximately $22.4 million representing accrued interest.

The remaining $80.0 million is available to indemnify the Company for certain pre-acquisition tax contingencies, related interest and penalties, and other matters pursuant to the Merger Agreement. Any amounts remaining after the settlement of all claims will be paid out to the selling shareholders. Remaining potential claims outstanding that may be indemnified pursuant to the Merger Agreement relate to former officers and stockholders’ suits that are still in litigation (See Note 22 to our consolidated financial statements).

During fiscal 2019, the Company accrued interest at a rate of 5% per six-month period on the unpaid DPO balance, net of any settled claims or payments, which was $80.0 million as of March 31, 2019 and 2018. Accordingly, $81.3 million was recorded within other current liabilities as of March 31, 2019 and 2018, representing the residual balances estimated to be paid to the selling shareholders subject to any remaining potential claims based on consideration of accrued interest and other matters.

A reconciliation of the principal balance of the DPO to the amount recorded in the consolidated balance sheets for the periods presented are as follows:

	March 31,
	2019		2018

Terms Loans and Revolving Credit Facility

On July 23, 2018 (the "Amendment Effective Date"), Booz Allen Hamilton Inc.("Booz Allen Hamilton") and Booz Allen Hamilton Investor Corporation ("Investor"), and certain wholly-owned subsidiaries of Booz Allen Hamilton, entered into the Sixth Amendment (the "Sixth Amendment") to the Credit Agreement (as amended, the "Credit Agreement"), dated as of July 31, 2012 among Booz Allen Hamilton, Investor, certain wholly owned subsidiaries of Booz Allen Hamilton and Bank of America, N.A., as Administrative Agent, Collateral Agent and Issuing Lender and the other lenders and financial institutions from time to time party thereto (as previously amended by the First Amendment to Credit Agreement, dated as of August 16, 2013, the Second Amendment to Credit Agreement, date as of May 7, 2014, the Third Amendment to the Credit Agreement, dated as of July 13, 2016, the Fourth Amendment to the Credit Agreement, dated as of February 6, 2017 and the Fifth Amendment to the Credit Agreement, dated as of March 7, 2018). The Sixth Amendment provides for a new delayed draw (the "Delayed Draw Facility") on the tranche A term loan ("Term Loan A") facility in the amount of up to $400.0 million and extended the maturity of the Term Loan A and the revolving credit facility (the "Revolving Credit Facility") to July 2023. Additionally, the Sixth Amendment reduced the interest rate spread applicable to Term Loan A and the Revolving Credit Facility from a range of 1.50% to 2.25% to a range of 1.25% to 2.00% based on consolidated net leverage. The interest rate applicable to the Term Loan B ("Term Loan B" and, together with Term Loan A, the "Term Loans") remained unchanged.

Prior to the Sixth Amendment, approximately $1,079.5 million was outstanding under Term Loan A. Pursuant to the Sixth Amendment, certain lenders converted their existing Term Loan A loans into a new tranche of Term Loan A loans in an aggregate amount, along with Term Loan A loans advanced by certain new lenders, of approximately $1,479.5 million, $400.0 million of which will be available as the Delayed Draw Facility. The Delayed Draw Facility is accessible for nine months from the Amendment Effective Date (the "Delayed Draw Availability Period"). The Company is able to draw on the facility up to two times during the Delayed Draw Availability Period in an amount per draw (x) of not less than $100.0 million per draw or (y) equal to the amount of unused commitments in respect of the Delayed Draw Facility remaining at the time of such borrowing. The proceeds from the new lenders were used to prepay in full all of the existing Term Loan A tranche. The proceeds of the Delayed Draw Facility will be used for general corporate purposes and other purposes not prohibited by the Credit Agreement.

Prior to the Sixth Amendment, $500.0 million was available under the revolving credit facility. Pursuant to the Sixth Amendment, certain lenders under the Existing Credit Agreement converted their Existing Revolving Commitments into a new tranche of revolving commitments (the "New Revolving Commitments" and the revolving credit loans made thereunder, the "New Revolving Loans") in an aggregate amount, along with New Revolving Commitments of certain new lenders, of $500.0 million.

As of March 31, 2019, the Credit Agreement provided the Company with a $1,037.7 million Term Loan A, a $400 million Delayed Draw Facility, and a $391.1 million Term Loan B and a $500.0 million revolving credit facility (the “Revolving Credit Facility”) with a sub-limit for letters of credit of $100.0 million. As of March 31, 2019, the maturity date of Term Loan A and the termination date for the Revolving Credit Facility was July 23, 2023 and the maturity date of Term Loan B was June 30, 2023. Booz Allen Hamilton’s obligations and the guarantors’ guarantees under the Credit Agreement are secured by a first priority lien on substantially all of the assets (including capital stock of subsidiaries) of Booz Allen Hamilton, Investor and the subsidiary guarantors, subject to certain exceptions set forth in the Credit Agreement and related documentation. Subject to specified conditions, without the consent of the then-existing lenders (but subject to the receipt of commitments), the Term Loans or Revolving Credit Facility may be expanded (or a new term loan facility or revolving credit facility added to the existing facilities) by up to greater of (x) $627 million and (y) 100% of consolidated EBITDA of Booz Allen Hamilton, as of the end of the most recently ended four quarter period for which financial statements have been delivered pursuant to the Credit Agreement plus (ii) the aggregate principal amount under which pro forma consolidated net secured leverage remains less than or equal to 3.50:1.00.

At Booz Allen Hamilton’s option, borrowings under the Secured Credit Facility bear interest based either at LIBOR (adjusted for maximum reserves, and subject to a floor of zero) for the applicable interest period or a base rate (equal to the highest of (x) the administrative agent’s prime corporate rate, (y) the overnight federal funds rate plus 0.50% and (z) three-month LIBOR (adjusted for maximum reserves, and subject to a floor of zero) plus 1.00%), in each case plus an applicable margin, payable at the end of the applicable interest period and in any event at least quarterly. The applicable margin for Term Loan A and borrowings under the Revolving Credit Facility ranges from 1.25% to 2.00% for LIBOR loans and 0.25% to 1.00% for base rate loans, in each case based on Booz Allen Hamilton’s consolidated total net leverage ratio. The applicable margin for Term Loan B is 2.00% for LIBOR loans and 1.00% for base rate loans. Unused commitments under the Revolving Credit Facility were, from the effective date of the Sixth Amendment until the delivery of financial statements for the first full fiscal quarter ending after the Sixth Amendment effective date pursuant to the Credit Agreement, subject to a quarterly fee of 0.25% and are, following such delivery of financial statements, subject to a quarterly fee ranging from 0.20% to 0.35% based on Booz Allen Hamilton’s consolidated total net leverage ratio. Until the Delayed Draw Facility was drawn down on April 23, 2019, commitments under the Delayed Draw Facility were subject to a quarterly fee ranging from 0.20% to 0.35% based on Booz Allen Hamilton's consolidated total net leverage ratio.

Booz Allen Hamilton occasionally borrows under the Revolving Credit Facility in anticipation of cash demands. During fiscal 2019 and 2018, Booz Allen Hamilton accessed a total of $110.0 million and $125.0 million, respectively, of its $500.0 million Revolving Credit Facility. As of March 31, 2019 and 2018, there was no outstanding balance on the Revolving Credit Facility.

The Credit Agreement, as amended, requires quarterly principal payments of 1.25% of the stated principal amount of Term Loan A until maturity, and quarterly principal payments of 0.25% of the stated principal amount of Term Loan B until maturity.

The Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants include limitations on the following, in each case subject to certain exceptions: (i) indebtedness and liens, (ii) mergers, consolidations or amalgamations, liquidations, wind-ups or dissolutions, and disposition of all or substantially all assets; (iii) dispositions of property; (iv) restricted payments; (v) investments; (vi) transactions with affiliates; (vii) change in fiscal periods; (viii) negative pledges; (ix) restrictive agreements; (x) line of business; and (xi) speculative hedging. The events of default include the following, in each case subject to certain exceptions: (a) failure to make required payments under the Secured Credit Facility; (b) material breaches of representations or warranties under the Secured Credit Facility; (c) failure to observe covenants or agreements under the Secured Credit Facility; (d) failure to pay or default under certain other material indebtedness; (e) bankruptcy or insolvency; (f) certain Employee Retirement Income Security Act, or ERISA events; (g) certain material judgments; (h) actual or asserted invalidity of the Guarantee and Collateral Agreements or the other security documents or failure of the guarantees or perfected liens thereunder; and (i) a change of control. In addition, Booz Allen Hamilton is required to meet certain financial covenants at each quarter end, namely Consolidated Net Total Leverage and Consolidated Net Interest Coverage Ratios. As of March 31, 2019 and 2018, Booz Allen Hamilton was in compliance with all financial covenants associated with its debt and debt-like instruments.

During fiscal 2019, interest payments of $41.9 million and $16.8 million were made for Term Loan A and Term Loan B, respectively. During fiscal 2018, interest payments of $38.1 million and $14.9 million were made for Term Loan A and Term Loan B, respectively.

Senior Notes

On April 25, 2017, Booz Allen Hamilton issued $350 million aggregate principal amount of its 5.125% Senior Notes (the "Senior Notes"), under an Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, certain subsidiaries of Booz Allen Hamilton, as guarantors (the "Subsidiary Guarantors"), and Wilmington Trust, National Association, as trustee, (the "Trustee"), as supplemented by the First Supplemental Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, the Subsidiary Guarantors and the Trustee. Each of Booz Allen Hamilton's existing and future domestic restricted subsidiaries that guarantee its obligations under the Secured Credit Facility and certain other indebtedness guarantee the Senior Notes on a senior unsecured basis. Interest is payable semi-annually on May 1 and November 1 of each year, beginning on November 1, 2017, and principal is due at maturity on May 1, 2025. In connection with the Senior Notes, the Company recognized $6.7 million of issuance costs, which were recorded as an offset against the carrying value of debt and will be amortized to interest expense over the term of the Senior Notes. During fiscal 2019 and 2018, interest payments of $17.9 million and $9.3 million were made for the Senior Notes.

Borrowings under the Term Loans, and if used, the Revolving Credit Facility, incur interest at a variable rate. In accordance with Booz Allen Hamilton's risk management strategy, Booz Allen Hamilton executed a series of interest rate swaps. As of March 31, 2019, Booz Allen Hamilton had interest rate swaps with an aggregate notional amount of $600 million. These instruments hedge the variability of cash outflows for interest payments on the floating potion of the term loan debt. The Company's objectives in using cash flow hedges are to reduce volatility due to interest rate movements and to add stability to interest expense (See Note 13 in our consolidated financial statements).

The following table summarizes required future debt principal repayments (in thousands):

Derivatives

DERIVATIVES

The Company utilizes derivative financial instruments to manage interest rate risk related to its variable rate debt. The Company’s objectives in using these interest rate derivatives, which were designated as cash flow hedges, are to manage its exposure to interest rate movements and reduce volatility to interest expense. During the third quarter of fiscal 2019, the Company entered into three forward starting floating-to-fixed interest rate swap agreements with three financial institutions with a start date of April 30, 2019, with an aggregate notional amount of $150 million. The aggregate notional amount of all interest rate swap agreements increased to $600 million as of March 31, 2019. The swaps have staggered maturities, ranging from June 30, 2021 to June 30, 2023. These swaps mature within the last tranche of the Company's floating rate debt (July 23, 2023).

The floating-to-fixed interest rate swaps involve the exchange of variable interest amounts from a counterparty for the Company making fixed-rate interest payments over the life of the agreements without exchange of the underlying notional amount and effectively converting a portion of the variable rate debt into fixed interest rate debt.

Derivative instruments are recorded in the consolidated balance sheet on a gross basis at estimated fair value. As of March 31, 2019, $1.8 million, $0.6 million, $0.9 million, and $4.3 million were classified as other current assets, other long-term assets, other current liabilities, and other long-term liabilities, respectively, on the consolidated balance sheet. As of March 31, 2018, $0.7 million and $7.2 million were classified as other current assets and other long-term assets, respectively, on the consolidated balance sheet.

For interest rate swaps designated as cash flow hedges, the changes in the fair value of derivatives is recorded in Accumulated Other Comprehensive Income, or AOCI, net of taxes, and is subsequently reclassified into interest expense in the period that the hedged forecasted interest payments are made on the Company's variable-rate debt. The effect of derivative instruments on the accompanying consolidated financial statements for fiscal years ended March 31, 2019 and 2018 is as follows:

Derivatives in Cash Flow Hedging Relationships	Amount of Gain or (Loss) Recognized in AOCI on Derivative					Location of Gain or Loss Recognized in Income on Derivative	Amount of Gain or (Loss) Reclassified from AOCI into Income				Interest Expense on Consolidated Statements of Operations
	2019			2018			2019		2018		2019			2018
Interest rate swaps	$	(9,772	)	$	7,926	Interest expense	$	1,026	$	—	$	(89,517	)	$	(82,269	)

Over the next 12 months, the Company estimates that $0.9 million will be reclassified as a decrease to interest expense. Cash flows associated with periodic settlements of interest rate swaps will be classified as operating activities in the consolidated statement of cash flows.

The Company is subject to counterparty risk in connection with its interest rate swap derivative contracts. Credit risk related to a derivative financial instrument represents the possibility that the counterparty will not fulfill the terms of the contract. The Company mitigates this credit risk by entering into agreements with credit-worthy counterparties and regularly reviews its credit exposure and the creditworthiness of the counterparties.

Income Taxes

INCOME TAXES

On December 22, 2017, Public Law No. 115-97, commonly referred to as the 2017 Tax Act, was enacted into law. The 2017 Tax Act included a number of changes to existing U.S. tax laws that impacted the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018. In addition, as a result of the tax rate change, the Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%.

In the third quarter of fiscal 2019 the Company completed its assessment for the income tax effects of the 2017 Tax Act, including true-up to all provisional amounts previously recorded, within the allowed one-year measurement period provided for under SAB118. Pursuant to SAB118, the Company finalized adjustments to provisional estimates as a reduction in the provision for income taxes of approximately $27.9 million that was primarily due to the measurement-period adjustment associated with an unbilled receivables methodology change effective as of March 31, 2018, which was approved by the IRS in the third quarter of fiscal 2019. All other adjustments to the provisional estimates that the Company recorded through the interim periods of fiscal 2019, such as the acceleration of depreciation and the limitation on the deductibility of certain executive compensation, were not material.

The components of income tax expense were as follows:

	Fiscal Year Ended March 31,

Deferred tax balances arise from temporary differences between the carrying amount of assets and liabilities and their tax basis and are stated at the enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided against deferred tax assets when it is more likely than not that some or all of the deferred tax asset will not be realized. In determining if the Company's deferred tax assets are realizable, management considers all positive and negative evidence, including the history of generating financial reporting earnings, future reversals of existing taxable temporary differences, projected future taxable income, as well as any tax planning strategies.

As of March 31, 2019, the Company has available federal, state, and foreign net operating loss ("NOL carryforwards") of $2.3 million, $0.4 million and $1.9 million, respectively, that may be applied against future taxable income. The net operating losses are primarily attributable to an acquisition and will begin to expire in fiscal 2037. A valuation allowance of $2.9 million related to net operating losses, has been recorded due to the uncertainty regarding the realization of the asset.

Uncertain Tax Positions

The Company maintains reserves for uncertain tax positions related to unrecognized income tax benefits. These reserves involve considerable judgment and estimation and are evaluated by management based on the best information available including changes in tax laws and other information. As of March 31, 2019, 2018, and 2017, the Company has recorded $11.5 million, $11.8 million, and $11.6 million, respectively, of reserves for uncertain tax positions which includes potential tax benefits of $11.1 million, $11.6 million, and $1.4 million, respectively, that, when recognized, impact the effective tax rate.

A reconciliation of the beginning and ending amount of potential tax benefits for the periods presented is as follows:

	March 31,
	2019			2018			2017
Beginning of year	$	11,608		$	11,588		$	1,449
Increases in prior year position	93			41			127
Increases in current year position	575			—			10,278

Lapse of statute of limitations	(462		)	(21		)	(266		)
End of year	$	11,083		$	11,608		$	11,588

The Company recognized (released) accrued interest and penalties of $0.2 million, $0.1 million and $(9) thousand for fiscal 2019, 2018, and 2017, respectively, related to the reserves for uncertain tax positions in the income tax provision. Included in the total reserve for uncertain tax positions are accrued penalties and interest of approximately $0.4 million, $0.2 million and $0.1 million at March 31, 2019, 2018, and 2017, respectively.

The Company is subject to taxation in the United States and various state and foreign jurisdictions. As of March 31, 2019, the Company's federal income tax returns and refund claims examination for fiscal years 2013 through 2015 has been completed by the IRS, resulting in an acceptance of the fully claimed amount of $10.9 million. The remaining jurisdictions' returns open for examination are not considered to be material.

The Company is currently contesting tax assessments from the District of Columbia Office of Tax and Revenue for fiscal years 2013 through 2015 at various stages of applicable administrative and judicial processes, with a combined amount at issue of approximately $11.4 million, net of associated tax benefits as of March 31, 2019. The Company has taken similar tax positions with respect to subsequent fiscal years, totaling in aggregate $27.4 million. As of March 31, 2019, the Company does not maintain reserves for any uncertain tax positions related to the contested tax benefits or the similar tax positions taken in the subsequent fiscal years. Given the Company's position on the recoverable nature of the state tax expense, it does not believe the resolution of these matters will have a material adverse effect on its results of operations, cash flows or financial condition.

Retirement Benefits [Abstract]

Employee Benefit Plans

EMPLOYEE BENEFIT PLANS

Defined Contribution Plan

The Company sponsors the Employees’ Capital Accumulation Plan, or ECAP, which is a qualified defined contribution plan that covers eligible U.S. and international employees. ECAP provides for distributions, subject to certain vesting provisions, to participants by reason of retirement, death, disability, or termination of employment. Effective April 1, 2014, the Company transitioned from a discretionary employer contribution to an annual matching contribution of up to 6% of eligible annual income as determined by the Internal Revenue Code for the ECAP. Total expense recognized under ECAP for fiscal 2019, 2018, and 2017 was $136.3 million, $126.9 million, and $116.6 million, respectively, and the Company-paid contributions were $130.9 million, $123.9 million, and $114.8 million, respectively.

Defined Benefit Plan and Other Postretirement Benefit Plans

The Company provides postretirement healthcare benefits to former officers under a medical indemnity insurance plan, with premiums paid by the Company. This plan is referred to as the Officer Medical Plan. The Company also established a non-qualified defined benefit plan for all officers in May 1995, or the Retired Officers' Bonus Plan, which pays a lump-sum amount of $10,000 per year of service as an officer, provided the officer meets retirement vesting requirements. In addition, the Company provides a fixed annual allowance after retirement to cover financial counseling and other expenses. The Retired Officers' Bonus Plan is not salary related, but rather is based primarily on years of service. During fiscal 2017, the Company adopted a new plan which will provide for a one-time, lump sum retirement payment of one month’s salary when a vice-president retires from the Company, effective April 1, 2017. This is referred to as the Retired Vice-President Bonus Plan.

The Company recognizes a liability for the defined benefit plans' underfunded status, measures the defined benefit plans' obligations that determine its funded status as of the end of the fiscal year, and recognizes as a component of accumulated other comprehensive income the changes in the defined benefit plans' funded status that are not recognized as components of net periodic benefit cost.

The components of net postretirement medical expense for the Officer Medical Plan were as follows:

	Fiscal Year Ended March 31,
	2019		2018		2017
Service cost	$	5,952	$	4,464	$	4,851
Interest cost	5,130		5,008		4,782
Net actuarial loss	2,108		2,271		3,052
Total postretirement medical expense	$	13,190	$	11,743	$	12,685

The service cost component of net periodic benefit cost is included in cost of revenue and general and administrative expenses, and the non-service cost components of net periodic benefit cost (interest cost and net actuarial loss) is included as part of other income (expense), net in the accompanying consolidated statements of operations.

The weighted-average discount rate used to determine the year-end benefit obligations was as follows:

	Fiscal Year Ended March 31,
	2019		2018		2017
Officer Medical Plan	4.10	%	4.10	%	4.30	%
Retired Officers’ Bonus Plan	4.10	%	4.10	%	4.30	%
Retired Vice Presidents' Bonus Plan	4.10	%	4.10	%	4.30	%

Assumed healthcare cost trend rates for the Officer Medical Plan at March 31, 2019 and 2018 were as follows:    

Pre-65 initial rate	2019		2018
Healthcare cost trend rate assumed for next year	7.50	%	7.75	%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)	4.50	%	4.50	%
Year that the rate reaches the ultimate trend rate	2027		2027

Post-65 initial rate	2019		2018
Healthcare cost trend rate assumed for next year	7.75	%	8.00	%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)	4.50	%	4.50	%
Year that the rate reaches the ultimate trend rate	2027		2027

Total defined benefit plan expense, consisting of service, interest, and net actuarial gain associated with the Retired Officers' Bonus Plan was $0.7 million for fiscal 2019, 2018, and 2017. Benefits paid associated with the Retired Officers’ Bonus Plan were $0.8 million, $1.5 million, and $0.9 million for fiscal 2019, 2018, and 2017, respectively. The end-of-period benefit obligation of $3.7 million and $3.8 million as of March 31, 2019 and 2018, respectively, is included in postretirement obligations within other long-term liabilities in the accompanying consolidated balance sheets.

Total defined benefit plan expense, consisting of service, interest, prior service cost, and net actuarial gain associated with the Retired Vice-President Bonus Plan was $0.2 million for fiscal 2019 and 2018. There was no defined benefit plan expense associated with the Retired Vice-President Bonus Plan for fiscal 2017. There were no benefits paid associated with the Retired Vice-President Bonus Plan for fiscal 2019, 2018, and 2017, respectively. The end-of-period benefit obligation associated with the Retired Vice-President Bonus Plan was $0.9 million as of March 31, 2019 and 2018, which are recorded as postretirement obligations within other long-term liabilities in the accompanying consolidated balance sheets.

Other comprehensive loss for fiscal 2019 includes unrecognized gross actuarial gain and prior service cost of $13.9 million, reduced by taxes of $3.6 million, that has not yet been recognized in net periodic pension cost for fiscal 2019 for the Retired Officers’ Bonus Plan, the Officer Medical Plan, and the Retired Vice-President Bonus Plan. Other comprehensive loss for fiscal 2018 includes unrecognized gross actuarial gain and prior service cost of $2.7 million, reduced by taxes of $1.0 million, that has not yet been recognized in net periodic pension cost for fiscal 2018 for the Retired Officers’ Bonus Plan, the Officer Medical Plan, and the Retired Vice-President Bonus Plan.

The changes in the benefit obligation, plan assets, and funded status of the Officer Medical Plan were as follows:

	Fiscal Year Ended March 31,
	2019			2018			2017
Benefit obligation, beginning of the year	$	126,886		$	118,089		$	114,008
Service cost	5,952			4,464			4,851
Interest cost	5,130			5,008			4,782
Net actuarial (gain) loss	(13,885		)	2,744			(2,219		)
Benefits paid	(3,742		)	(3,419		)	(3,333		)
Benefit obligation, end of the year	$	120,341		$	126,886		$	118,089

The net benefit obligation gain in fiscal 2019 was due mainly to the favorable medical cost experience in the past year as well as updates to demographic assumptions. The net benefit obligation loss in fiscal 2018 was due largely to a decrease in the discount rate and an updated outlook of higher future medical inflation offset by favorable medical cost experience in the past year. The net benefit obligation gain in fiscal 2017 was due to an increase in the discount rate as well as an update to mortality improvement assumptions.

As of March 31, 2019 and 2018, the unfunded status of the Officer Medical Plan was $120.2 million and $126.9 million, respectively, which is included in other long-term liabilities in the accompanying consolidated balance sheets.

Funded Status for Defined Benefit Plans

Generally, annual contributions are made at such times and in amounts as required by law and may, from time to time, exceed minimum funding requirements. The Retired Officers’ Bonus Plan and the Retired Vice-President Bonus Plan are unfunded plans and contributions are made as benefits are paid. As of March 31, 2019 and 2018, there were no plan assets for either the Retired Officers’ Bonus Plan or the Retired Vice-President Bonus Plan and therefore, the accumulated liability of $4.6 million and $4.7 million, respectively, is unfunded. The liability will be distributed in a lump-sum payment as each officer or vice-president retires.

The expected future medical benefit payments and related contributions are as follows:

For the Fiscal Year Ending March 31,
2020	$	3,688
2021	$	4,013
2022	$	4,403
2023	$	5,231
2024	$	5,743
2025 - 2029	$	34,061

Long-term Disability Benefits

The Company offers medical and dental benefits to inactive employees (and their eligible dependents) on long-term disability. These benefits do not vary with an employee's years of service; therefore, the Company is required to accrue the costs of the benefits at the date the inactive employee becomes disability eligible and elects to participate in the benefit. The accrued cost for such benefits is calculated using an actuarial estimate. The accrued cost for these benefits was $11.6 million and $22.8 million at March 31, 2019 and 2018, respectively, and are presented in other long-term liabilities in the accompanying consolidated balance sheets.

During the third quarter of fiscal 2019, the long-term disability plan was amended to make Medicare the first payer of eligible medical benefits, with any excess benefits becoming the obligation of the Company. The amendment caused a re-measurement of the plan liability during the period resulting in a reduction of $11.2 million recorded in general and administrative expenses.

Deferred Compensation Plan

The Company established a non-qualified deferred compensation plan (the "Plan") for certain executives and other highly compensated employees that was effective in fiscal 2018. Pursuant to the Plan, participants are eligible to defer up to 100% of their incentive cash compensation on a tax deferred basis in excess of the IRS limits imposed on 401(k) plans. The assets of the plan are held in a consolidated trust and are subject to the claims of the Company's general creditors under federal and state laws in the event of insolvency. Consequently, the trust qualifies as a Rabbi trust for income tax purposes.

As of March 31, 2019, $3.2 million of plan investments and obligations were recorded in other long term assets and in other long term liabilities, respectively, in the condensed consolidated balance sheets, representing the fair value related to the deferred compensation plan. Adjustments to the fair value of the plan investments and obligations are recorded in operating expenses.

Equity [Abstract]

Stockholders' Equity

STOCKHOLDERS’ EQUITY

Common Stock

Holders of Class A Common Stock are entitled to one vote for each share.

Each share of common stock is entitled to participate equally in dividends, when and if declared by the Board of Directors from time to time, such dividends and other distributions in cash, stock, or property from the Company’s assets or funds become legally available for such purposes subject to any dividend preferences that may be attributable to preferred stock that may be authorized. The Company’s ability to pay dividends to stockholders is limited as a practical matter by restrictions in the credit agreements governing the Senior Credit Facilities.

The authorized and unissued Class A Common Stock shares are available for future issuance upon share option exercises, without additional stockholder approval.

Employee Stock Purchase Plan

In connection with the Company’s initial public offering in November 2010, the Company established a tax qualified Employee Stock Purchase Plan, or ESPP, which is designed to enable eligible employees to periodically purchase shares of the Company’s Class A Common Stock up to an aggregate of 10,000,000 shares at a five percent discount from the fair market value of the Company’s common stock. The ESPP provides for quarterly offering periods, the first of which commenced on April 1, 2011. For the year ended March 31, 2019, 242,706 Class A Common Stock shares were purchased by employees under the ESPP. Since the program's inception, 2,431,993 shares have been purchased by employees.

Share Repurchase Program

On December 12, 2011, the Board of Directors approved a $30.0 million share repurchase program, to be funded from cash on hand. A special committee of the Board of Directors was appointed to evaluate market conditions and other relevant factors and initiate repurchases under the program from time to time. On January 27, 2015, January 25, 2017, November 2, 2017, and May 24, 2018, the Board of Directors approved increases to the share repurchase authorization to $180.0 million, $410.0 million, $610.0 million, and $910.0 million, respectively. The share repurchase program may be suspended, modified or discontinued at any time at the Company’s discretion without prior notice. During fiscal 2019, the Company purchased 5.1 million shares of the Company’s Class A Common Stock in a series of open market transactions for $239.8 million. During fiscal 2018, the Company purchased 7.2 million shares of the Company’s Class A Common Stock in a series of open market transactions for $257.6 million. As of March 31, 2019, the Company had $258.2 million remaining under the repurchase program.

Equity Incentive Plan

The Company's Equity Incentive Plan, or EIP, was adopted in connection with the Merger Agreement for employees and directors of Holding. The EIP was amended and restated in 2010 in connection with the Company’s initial public offering, and was again amended and restated on May 22, 2014. Awards under the EIP may be made in the form of stock options; stock purchase rights; restricted stock; restricted stock units; performance shares; performance units; stock appreciation rights; deferred share units; dividend equivalents; and other stock-based awards.

Stock Options

Stock options under the EIP are granted at the discretion of the Board of Directors or its Compensation Committee and expire ten years from the grant date. Stock options generally vest in equal installments over a five-year period subject to the grantee’s continued service on each applicable vesting. All options under the EIP are exercisable, upon vesting, for shares of Class A common stock of Holding. The following table summarizes options granted under the Amended and Restated Equity Incentive Plan, or EIP during fiscal 2019:

Grant Date	Options Granted	Estimated Fair Value per Option Grant		Total Fair Value

The aggregate grant date fair value of the EIP Options issued during fiscal 2019 and 2018, was $3.5 million and $3.7 million, respectively, and is being recorded as expense over the vesting period. The total fair value of EIP Options vested during fiscal 2019 and 2018 was $2.5 million and $2.7 million, respectively. The total intrinsic value of EIP options exercised during fiscal 2019 and 2018 was $47.2 million and $36.7 million, respectively. As of March 31, 2019 and 2018, there were 10,708,159 and 11,434,181 options, respectively, available for future grant under the EIP.

Annual Incentive Plans

On October 1, 2010, the Board of Directors adopted an Annual Incentive Plan (or “AIP”) in connection with the initial public offering to more appropriately align the Company’s compensation programs with those of similarly situated companies. The amount of the annual incentive payment is determined based on performance targets established by the Board of Directors and a portion of the bonus may be paid in the form of equity (including stock and other awards under the EIP). For bonus periods prior to the 2018 fiscal year, if the Board of Directors elected to make a portion of the payments in equity, the value of the portion of the AIP award paid in equity was increased by 20%. Such equity awards vest over a three-year period subject to the employee’s continued service to the Company. The portion paid in the form of equity was recognized in the accompanying consolidated statements of operations based on grant date fair value over the vesting period of three years. The portion paid in cash was accrued ratably during the fiscal year in which the employees provide service and paid out during the first quarter of the subsequent fiscal year.

During fiscal 2018, the Company implemented a new annual incentive program for officers. The equity compensation would be issued in the form of restricted stock units of which a portion would vest based on the passage of time, and the other portion would vest based on specified performance conditions to be achieved over a specified time period. A restricted stock unit represents a contingent right to receive one share of Class A Common Stock upon vesting. Service-based restricted stock units vest in equal installments over a three-year period subject to the grantee's continued service on each applicable vesting date and are settled for shares of the Company's common stock. Dividend equivalents are paid in respect of the service-based restricted stock units when dividends are paid on the Company's common stock. Performance-based awards vest at the end of a three-year period subject to certain specified financial performance criteria and the grantee's continued service through the period. These awards are settled for Company Class A Common Stock and dividend equivalents. Compensation expense for performance-based awards during the performance period is estimated at each reporting date using management's expectation of the probable achievement of the specified performance criteria.

Grants of Class A Restricted Common Stock and Restricted Stock Units

During fiscal 2019, the Board of Directors granted an aggregate of 610,477 Restricted Stock Units with service-based and performance-based vesting conditions to existing officers and vice presidents of the Company, as well as to newly promoted and hired partners and vice presidents. A portion of these awards were issued in conjunction with the Annual Incentive Plan, whereby a portion of the incentive payment was paid in the form of Restricted Stock Units. The awards issued to newly hired and promoted employees will vest over a three-year period subject to the employees' continued employment with the Company.

The Board of Directors also granted 44,420 shares of Class A Restricted Common Stock to members of the Board of Directors during fiscal 2019. These awards generally vest over one year.

The aggregate fair value of all awards issued during fiscal 2019 was $27.8 million and was based on the grant date stock price, which ranged from $41.28 to $51.82. This amount will be recognized in the accompanying consolidated statements of operations over the applicable vesting period of the awards.

The total fair value of restricted stock shares vested during fiscal 2019 and 2018 was $21.5 million and $26.7 million, respectively.

As permitted under the terms of the EIP, the Compensation Committee, as Administrator of the Plan, authorized the withholding of taxes not to exceed the minimum statutory withholding amount, through the surrender of shares of Class A common stock issuable upon the vesting or accelerated vesting of Restricted Stock. As a result of these transactions, the Company repurchased 198,231 shares and recorded them as treasury shares at a total cost of $10.2 million in fiscal 2019.

Methodology

The Company uses the Black-Scholes option-pricing model to determine the estimated fair value for stock-based awards. The fair value of the Company’s stock is based on the closing price on the New York Stock Exchange on the date of grant.

During fiscal 2019, the Company’s Board of Directors authorized and declared three quarterly cash dividends of $0.19 per share and one quarterly cash dividend of $0.23 per share. Therefore, an annualized dividend yield between 1.66% and 2.46% was used in the Black-Scholes option-pricing model for all grants issued during the fiscal year. The Company plans to continue paying recurring dividends in the near term and assessing its excess cash resources to determine the best way to utilize its excess cash flow to meet its objectives. One way the Company may utilize excess cash includes the payment of special dividends. The Company does not anticipate or forecast the payment of special dividends and therefore does not include special dividends in the annual dividend yield that the company uses to calculate the fair value of stock options, as the Company does not pay these special dividends on a regular basis.

Implied volatility is calculated as of each grant date based on our historical volatility. Other than the expected life of the option, volatility is the most sensitive input to our option grants.

The risk-free interest rate is determined by reference to the U.S. Treasury yield curve rates with the remaining term equal to the expected life assumed at the date of grant. The average expected life is calculated based on the Company's historical experience with respect to its stock plan activity in combination with an estimate of when vested and unexercised option shares will be exercised. Forfeitures were estimated based on the Company’s historical analysis of officer and vice-president attrition levels and actual forfeiture rates by grant date.

The weighted average assumptions used in the Black-Scholes option-pricing model for stock option awards were as follows:

	For The Fiscal Year Ended March 31,
	2019			2018			2017
Dividend yield	2.01		%	1.90		%	1.94		%

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

Leases

The Company leases office space under noncancelable operating leases that expire at various dates through fiscal 2031. The terms for the facility leases generally provide for rental payments on a graduated scale, which are recognized on a straight-line basis over the terms of the leases, including reasonably assured renewal periods, from the time the Company controls the leased property. Sometimes lease payments include payments for insurance, maintenance, and property taxes. There are no purchase options on operating leases at terms favorable to market rents. Lease incentives are recorded as a deferred credit and recognized as a reduction to rent expense on a straight-line basis over the lease term. Rent expense was approximately $82.7 million, net of $0.6 million of sublease income, $81.2 million, net of $0.6 million of sublease income, and $81.6 million, net of $0.5 million of sublease income, for fiscal 2019, 2018, and 2017, respectively.

Future minimum operating lease payments for noncancelable operating leases and future minimum income for noncancelable sublease rentals are summarized as follows:

For the Fiscal Year Ending March 31,	Operating Lease Payments		Operating Sublease Income
2020	$	70,614	$	129
2021	68,888		12
2022	58,325		5
2023	53,463		—
2024	46,222		—
Thereafter	125,399		—
	$	422,911	$	146

Rent expense is included in occupancy costs, a component of general and administrative expenses, as shown on the consolidated statements of operations, and includes rent, sublease income from third parties, real estate taxes, utilities, parking, security, repairs and maintenance, and storage costs.

Letters of Credit and Third-Party Guarantees

As of March 31, 2019 and 2018, the Company was contingently liable under open standby letters of credit and bank guarantees issued by our banks in favor of third parties that totaled $9.5 million and $6.3 million, respectively. These letters of credit and bank guarantees primarily support insurance and bid and performance obligations. At March 31, 2019 and 2018, approximately $1.0 million and $1.4 million, respectively, of these instruments reduce the available borrowings under the Revolving Credit Facility. The remainder is guaranteed under a separate $15.0 million facility established in fiscal 2015 of which $6.5 million and $10.1 million, respectively, was available to the Company at March 31, 2019 and 2018.

Government Contracting Matters

For fiscal 2019, 2018, and 2017, approximately 96%, 97%, and 97%, respectively, of the Company’s revenue was generated from contracts where the end user was an agency or department of the U.S. government, including contracts where the Company performed in either as a prime contractor or subcontractor, and regardless of the geographic location in which the work was performed. U.S. government contracts and subcontracts are subject to extensive legal and regulatory requirements. From time to time and in the ordinary course of business, agencies of the U.S. government audit our contract costs and conduct inquiries and investigations of our business practices with respect to government contracts to determine whether the Company’s operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government agencies, including the Defense Contract Audit Agency, routinely audit our contract costs, including allocated indirect costs, for compliance with the Cost Accounting Standards and the Federal Acquisition Regulation. These agencies also conduct reviews and investigations and make inquiries regarding our accounting and other systems in connection with our performance and business practices with respect to our government contracts and subcontracts. U.S. government audits, inquiries, or investigations of the Company, whether related to the Company’s U.S. government contracts or subcontracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including withholding of payments, suspension of payments, repayments, fines, or penalties being imposed upon the Company, or could lead to suspension or debarment from future U.S. government contracting. Management believes it has recorded the appropriate provision for any such audit, inquiry, or investigation of which it is aware. Management believes it has recorded the appropriate provision for the estimated losses that may be experienced from any such reductions and/or penalties. As of March 31, 2019 and 2018, the Company has recorded a liability of approximately $195.3 million and $168.6 million, respectively, for its current best estimate of amounts to be refunded to customers for potential adjustments from audits or reviews of contract costs incurred subsequent to fiscal year 2011, and for contracts not yet closed that are impacted by settlement of audits or reviews of contract costs incurred in prior fiscal years.

Litigation

The Company is involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with clients and contractors, intellectual property disputes, and other business matters. These legal proceedings seek various remedies, including claims for monetary damages in varying amounts, none of which are considered material, or are unspecified as to amount. Although the outcome of any such matter is inherently uncertain and may be materially adverse, based on current information, management does not expect any of the currently ongoing audits, reviews, investigations, or litigation to have a material adverse effect on the Company’s financial condition and results of operations. As of March 31, 2019 and 2018, there were no material amounts accrued in the consolidated financial statements related to these proceedings.

Six former officers and stockholders who had departed the company prior to the acquisition of the Company by the Carlyle Group (the "Carlyle Acquisition") have filed a total of nine suits in various jurisdictions, with original filing dates ranging from July 3, 2008 through December 15, 2009, against us and certain of our current and former directors and officers. Three of these suits were amended on July 2, 2010 and then further amended into one consolidated complaint on September 7, 2010. Another two of the original nine suits were consolidated into one complaint on September 24, 2014. Each of the suits arises out of the Carlyle Acquisition and alleges that the former stockholders are entitled to certain payments that they would have received if they had held their stock at the time of the Carlyle Acquisition. Some of the suits also allege that the acquisition price paid to stockholders was insufficient. The various suits assert claims for breach of contract, tortious interference with contract, breach of fiduciary duty, civil Racketeer Influenced and Corrupt Organizations Act, or RICO, violations, violations of the ERISA, and/or securities and common law fraud. Three of these suits have been dismissed with all appeals exhausted. The two suits that were consolidated into one action on September 24, 2014 were settled on April 16, 2015. One of the remaining suits has been dismissed by the United States District Court for the Southern District of California and such dismissal was upheld by the United States Court of Appeals for the Ninth Circuit. The plaintiff in this suit subsequently filed a Petition for Writ of Certiorari to the United States Supreme Court, which was denied by the United States Supreme Court on January 9, 2017. The other three remaining suits that were previously consolidated on September 7, 2010 have been dismissed by the United States District Court for the Southern District of New York and were on appeal before the United States Court of Appeals for the Second Circuit. On July 13, 2017, the United States Court of Appeals for the Second Circuit affirmed the ruling of the United States District Court for the Southern District of New York, except for one plaintiff’s securities fraud claim, which was remanded to the United States District Court for the Southern District of New York to give the plaintiff, Paul Kocourek, leave to file another amended complaint to attempt to plead a securities fraud claim. On April 6, 2018, the plaintiff filed an amended complaint in which Mr. Kocourek, individually, as Trustee of the Paul Kocourek Trust and on behalf of the putative class, alleges that the Company and certain former officers and directors violated Sections 10(b), 20(a) and 14(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). On April 25, 2018, the court entered an order postponing the deadline within which the defendants must answer or move to dismiss the amended complaint. A lead plaintiff has not been appointed. On August 2, 2018, the defendants filed a motion to dismiss the amended complaint. On September 17, 2018, the plaintiff filed an opposition to the defendants’ motion to dismiss the amended complaint. The defendants filed their reply to plaintiff's opposition on October 17, 2018.

As of March 31, 2019, the aggregate alleged damages that will be sought in the remaining suit is unknown. As of March 31, 2019, although the outcome of any of these cases is inherently uncertain and may be materially adverse, based on current information, management does not expect them to have a material adverse effect on our financial condition and results of operations.

On June 7, 2017, Booz Allen Hamilton Inc. was informed that the U.S. Department of Justice (DOJ) is conducting a civil and criminal investigation of the Company. In connection with the investigation, the DOJ has requested information from the Company relating to certain elements of the Company’s cost accounting and indirect cost charging practices with the U.S. government. Since learning of the investigation, the Company has engaged a law firm experienced in these matters to represent the Company in connection with this matter and respond to the government's requests. As is commonly the case with this type of matter, the Company has also been in contact with other regulatory agencies and bodies, including the Securities and Exchange Commission, which notified the Company that it is conducting an investigation that the Company believes relates to matters that are also the subject of the DOJ's investigation. The Company may receive additional regulatory or governmental inquiries related to the matters that are the subject of the DOJ's investigation. In accordance with the Company's practice, the company is cooperating with all relevant government parties. The total cost associated with these matters will depend on many factors, including the duration of these matters and any related findings. At this stage, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with these matters.

On June 19, 2017, a purported stockholder of the Company filed a putative class action lawsuit in the United States District Court for the Eastern District of Virginia styled Langley v. Booz Allen Hamilton Holding Corp., No. 17-cv-00696 naming the Company, its Chief Executive Officer and its Chief Financial Officer as defendants purportedly on behalf of all purchasers of the Company’s securities from May 19, 2016 through June 15, 2017. On September 5, 2017, the court named two lead plaintiffs and on October 20, 2017, the lead plaintiffs filed a consolidated amended complaint. The complaint asserts claims under Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 promulgated thereunder, alleging misrepresentations or omissions by the Company purporting to relate to matters that are the subject of the DOJ investigation described above. The plaintiffs seek to recover from the Company and the individual defendants an unspecified amount of damages. The Company believes the suit lacks merit and intends to defend against the lawsuit. Motions to dismiss were argued on January 12, 2018, and on February 8, 2018, the court dismissed the amended complaint in its entirety without prejudice. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

On November 13, 2017, a Verified Shareholder Derivative Complaint was filed in the United States District Court for the District of Delaware styled Celine Thum v. Rozanski et. al., C.A. No. 17-cv-01638, naming the Company as a nominal defendant and numerous current and former officers and directors as defendants. The complaint asserts claims for breach of fiduciary duties, unjust enrichment, waste of corporate assets, abuse of control, gross mismanagement, and violations of Sections 14(a), 10(b) and 20(a) of the Exchange Act, purportedly relating to matters that are the subject of the DOJ investigation described above. The parties have stipulated to a stay of the proceedings pending the outcome of the securities litigation (described above), which the court so ordered on January 24, 2018. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

Fair Value Measurements

FAIR VALUE MEASUREMENTS

The accounting standard for fair value measurements establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3).

A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The financial instruments measured at fair value in the accompanying consolidated balance sheets consist of the following:

	Recurring Fair Value Measurements as of March 31, 2019

(1) The Company’s interest rate swaps are considered over-the-counter derivatives and fair value is estimated based on the present value of future cash flows using a model-derived valuation that uses Level 2 observable inputs such as interest rate yield curves. See Note 13 to our consolidated financial statements for further discussion on the Company’s derivative instruments designated as cash flow hedges.

(2) Investments in this category consist of primarily of mutual funds whose fair values are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. These assets represent investments held in a consolidated trust to fund the Company's non-qualified deferred compensation plan and are recorded in other long-term assets and other long-term liabilities on our consolidated balance sheets.

(3) The Company recognized a contingent consideration liability of 3.6 million in connection with the acquisition of Aquilent in fiscal 2017. As of March 31, 2019 and 2018, the estimated fair value of the contingent consideration liability was $1.2 million and $3.6 million, respectively, and was valued using probability-weighted cash flows, which is based on the use of Level 3 fair value measurement inputs. The fair value of the contingent consideration decreased by $2.4 million as the Company finalized the indemnification payments to the selling shareholders. During the third quarter of fiscal 2019, the Company recorded the decrease of payments in other income as a result of the fair value change and the liability is recorded in other long-term liabilities in the consolidated balance sheet.

The fair value of the Company's cash and cash equivalents, which are primarily Level 1 inputs, approximated its carrying values at March 31, 2019 and 2018. The fair value of the Company's debt instruments approximated its carrying value at March 31, 2019 and 2018. The fair value of debt is determined using quoted prices or other market information obtained from recent trading activity of each debt tranche in markets that are not active (Level 2 inputs). The fair value is corroborated by prices derived from the interest rate spreads of recently completed leveraged loan transactions of a similar credit profile, industry, and terms to that of the Company. The fair value of Senior Notes is determined using quoted prices or other market information from recent trading activity in the high-yield bond market (Level 2 inputs).

Interest Rate Swaps

Between April 2, 2019 and April 4, 2019, Booz Allen Hamilton entered into eight interest rate swap agreements with six different financial institutions to fix the LIBOR portion of the interest rate on outstanding debt under the Credit Agreement, as amended. Each swap has a notional amount of $50 million and fixes LIBOR at rates ranging from 2.2585% to 2.3075% with an effective date of April 30, 2019 and maturity dates of June 30, 2024 and June 30, 2025.

Delayed Draw Facility

On April 23, 2019, Booz Allen Hamilton drew down $400 million of the $400 million delayed draw Term Loan A available under the Company’s term loan facility. The Company did not incur any additional fees related to the borrowing of the loans. The Company expects that the proceeds will be used for general corporate purposes and other purposes not prohibited by the Credit Agreement.

Shares repurchased and withheld to cover taxes

The Company paid $6.3 million during the first quarter of fiscal 2020 for 108,617 shares of Class A Common Stock withheld to cover taxes related to Restricted Stock vesting during the fourth quarter of fiscal 2019 that had not settled in cash by March 31, 2019.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP, and the rules and regulations of the U.S. Securities and Exchange Commission, or SEC. All intercompany balances and transactions have been eliminated in consolidation.

The consolidated financial statements and notes of the Company include its subsidiaries, and the joint ventures and partnerships over which the Company has a controlling financial interest. The Company uses the equity method to account for investments in entities that it does not control if it is otherwise able to exert significant influence over the entities' operating and financial policies.

The Company’s fiscal year ends on March 31 and unless otherwise noted, references to fiscal year or fiscal are for fiscal years ended March 31.

Reclassification

Certain amounts reported in the Company's prior year consolidated financial statements have been reclassified to conform to the current year presentation.

Accounting Estimates

Accounting Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Areas of the consolidated financial statements where estimates may have the most significant effect include contractual and regulatory reserves, valuation and lives of tangible and intangible assets, contingent consideration related to business acquisitions, impairment of long-lived assets, accrued liabilities, revenue recognition, including the accrual of indirect costs, bonus and other incentive compensation, stock-based compensation, reserves for tax benefits and valuation allowances on deferred tax assets, provisions for income taxes, postretirement obligations, certain deferred costs, collectability of receivables, and loss accruals for litigation. Actual results experienced by the Company may differ materially from management's estimates.

Revenue Recognition

Revenue Recognition

The Company's revenues from contracts with customers (clients) are derived from offerings that include consulting, analytics, digital solutions, engineering, and cyber services, substantially with the U.S. government and its agencies, and to a lesser extent, subcontractors. The Company also serves foreign governments, as well as domestic and international commercial clients. The Company performs under various types of contracts, which include cost-reimbursable-plus-fee contracts, time-and-material contracts, and fixed-price contracts.

The Company considers a contract with a customer to exist under Topic 606, when there is approval and commitment from both the Company and the customer, the rights of the parties and payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. The Company also will consider whether two or more contracts entered into with the same customer should be combined and accounted for as a single contract. Furthermore, in certain transactions with commercial clients and with the U.S. government, the Company may commence providing services prior to receiving a formal approval from the customer. In these situations, the Company will consider the factors noted above, the risks associated with commencing the work and legal enforceability in determining whether a contract with the customer exists under Topic 606.

Customer contracts are often modified to change the scope, price, specifications or other terms within the existing arrangement. Contract modifications are evaluated by management to determine whether the modification should be accounted for as part of the original performance obligation(s) or as a separate contract. If the modification adds distinct goods or services and increases the contract value proportionate to the stand-alone selling price of the additional goods or services, it will be accounted for as a separate contract. Generally, the Company’s contract modifications do not include goods or services which are distinct, and therefore are accounted for as part of the original performance obligation(s) with any impact on transaction price or estimated costs at completion being recorded as through a cumulative catch-up adjustment to revenue.

The Company evaluates each service deliverable contracted with the customer to determine whether it represents promises to transfer distinct goods or services. Under Topic 606, these are referred to as performance obligations. One or more service deliverables often represent a single performance obligation. This evaluation requires significant judgment and the impact of combining or separating performance obligations may change the time over which revenue from the contract is recognized. The Company’s contracts generally provide a set of integrated or highly interrelated tasks or services and are therefore accounted for as a single performance obligation. However, in cases where we provide more than one distinct good or service within a customer contract, the contract is separated into individual performance obligations which are accounted for discretely.

Contracts with the U.S. government are subject to the Federal Acquisition Regulation ("FAR") and are priced based on estimated or actual costs of providing the goods or services. The Company derives a majority of its revenue from contracts awarded through a competitive bidding process. Pricing for non-U.S. government agencies and commercial customers is based on discrete negotiations with each customer. Certain of the Company’s contracts contain award fees, incentive fees or other provisions that may increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and may be based upon customer discretion. Management estimates variable consideration as the most likely amount that we expect to achieve based on our assessment of the variable fee provisions within the contract, prior experience with similar contracts or clients, and management’s evaluation of the performance on such contracts. The Company may perform work under a contract that has not been fully funded if the work has been authorized by the management and the customer to proceed. The Company evaluates unfunded amounts as variable consideration in estimating the transaction price. We include the estimated variable consideration in our transaction price to the extent that it is probable that a significant reversal of revenue will not occur upon the ultimate settlement of the variable fee provision. In the limited number of situations where our contracts with customers contain more than one performance obligation, the Company allocates the transaction price of a contract between the performance obligations in the proportion to their respective stand-alone selling prices. The Company generally estimates the stand-alone selling price of performance obligations based on an expected cost-plus margin approach as allowed under Topic 606. Our U.S. government contracts generally contain FAR provisions that enable the customer to terminate a contract for default or for the convenience of the U.S. government.

The Company recognizes revenue for each performance obligation identified within our customer contracts when, or as, the performance obligation is satisfied by transferring the promised goods or services. Revenue may either be recognized over time, or at a point in time. The Company generally recognizes revenue over time as our contracts typically involve a continuous transfer of control to the customer. A continuous transfer of control under contracts with the U.S. government and its agencies is evidenced by clauses which require the Company to be paid for costs incurred plus a reasonable margin in the event that the customer unilaterally terminates the contract for convenience. For contracts where the Company recognizes revenue over time, a contract cost-based input method is generally used to measure progress towards satisfaction of the underlying performance obligation(s). Contract costs include direct costs such as materials, labor and subcontract costs, as well as indirect costs identifiable with, or allocable to, a specific contract that are expensed as incurred. The Company does not incur material incremental costs to acquire or fulfill contracts. Under a contract cost-based input method, revenue is recognized based on the proportion of contract costs incurred to the total estimated costs expected to be incurred upon completion of the underlying performance obligation. The Company includes generally both funded and unfunded portions of customer contracts in this estimation process.

For interim financial reporting periods, contract revenue attributable to indirect costs is recognized based upon agreed-upon annual forward-pricing rates established with the U.S. government at the start of each fiscal year. Forward pricing rates are estimated and agreed upon between the Company and the U.S. government and represent indirect contract costs required to execute and administer contract obligations. The impact of any agreed-upon changes, or changes in the estimated annual forward-pricing rates, will be recorded in the interim financial reporting period when such changes are identified. This change relates to the interim financial reporting period differences between the actual indirect cost incurred and allocated to customer contracts compared to the estimated amounts allocated to contracts using the estimated annual forward-pricing rates established with the U.S. government.

On certain contracts, principally time-and-materials and cost-reimbursable-plus-fee contracts, revenue is recognized using the right-to-invoice practical expedient as the Company is contractually able to invoice the customer based on the control transferred. However, we did not elect to use the practical expedient which would allow the Company to exclude contracts recognized using the right-to-invoice practical expedient from the remaining performance obligations disclosed below. Additionally, for stand-ready performance obligations to provide services under fixed-price contracts, revenue is recognized over time using a straight-line measure of progress as the control of the services is provided to the customer ratably over the term of the contract. If a contract does not meet the criteria for recognition of revenue over time, we recognize revenue at the point in time when control of the good or service is transferred to the customer. Determining a measure of progress towards the satisfaction of performance obligations requires management to make judgments that may affect the timing of revenue recognition.

In addition to the right-to-invoice practical expedient discussed above, the Company applied certain other practical expedients permitted by Topic 606, which include: a) using the portfolio approach where contracts with similar characteristics were assessed collectively to evaluate risk of being impacted by the adoption of Topic 606; b) applying the practical expedient allowing the Company to not restate completed contracts which began and ended in the same fiscal year prior to the date of the initial adoption; and c) electing to omit the disclosure related to remaining performance obligations for reporting periods presented before the date of the initial adoption.

Many of our contracts recognize revenue under a contract cost-based input method and require an Estimate-at-Completion (EAC) process, which management uses to review and monitor the progress towards the completion of our performance obligations. Under this process, management considers various inputs and assumptions related to the EAC, including, but not limited to, progress towards completion, labor costs and productivity, material and subcontractor costs, and identified risks. Estimating the total cost at completion of performance obligations is subjective and requires management to make assumptions about future activity and cost drivers under the contract. Changes in these estimates can occur for a variety of reasons and, if significant, may impact the profitability of the Company’s contracts. Changes in estimates related to contracts accounted for under the EAC process are recognized in the period when such changes are made on a cumulative catch-up basis. If the estimate of contract profitability indicates an anticipated loss on a contract, the Company recognizes the total loss at the time it is identified. For fiscal years ended March 31, 2019, 2018 and 2017, the aggregate impact of adjustments in contract estimates was not material.

Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations do not include negotiated but unexercised options or the unfunded value of expired contracts.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents include operating cash on hand and highly liquid investments having a weighted average maturity of 60 days or less and a weighted average life of 120 days or less. The Company’s cash equivalents consist primarily of government money market funds and money market deposit accounts. The Company maintains its cash and cash equivalents in bank accounts that, at times, exceed the federally insured FDIC limits. The Company has not experienced any losses in such accounts.

Valuation of Accounts Receivable

Valuation of Accounts Receivable

The Company maintains allowances for doubtful accounts against certain billed and unbilled receivables based upon the latest information regarding whether specific charges are recoverable or invoices are ultimately collectible. Assessing the recoverability of charges and collectability of customer receivables requires management judgment. The Company determines its allowance for doubtful accounts by specifically analyzing individual accounts receivable, historical bad debts, customer credit-worthiness, current economic conditions, accounts receivable aging trends for billed receivables, availability of funding, compliance with contractual terms and conditions, client satisfaction with work performed, and other factors impacting unbilled receivables. Valuation reserves are periodically re-evaluated and adjusted as more information about the ultimate recoverability and collectability of accounts receivable becomes available. Upon determination that a receivable is uncollectible, the receivable balance and any associated reserve are written off.

Concentrations of Credit Risk

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents and accounts receivable. The Company’s cash equivalents are generally invested in U.S. government money market funds and money market deposit accounts. The Company believes that credit risk for accounts receivable is limited as the receivables are primarily with the U.S. government.

Property and Equipment

Property and Equipment

Property and equipment are recorded at cost, and the balances are presented net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. Furniture and equipment is depreciated over five to ten years, and computer equipment is depreciated over four years. Leasehold improvements are amortized over the shorter of the useful life of the asset or the lease term. Maintenance and repairs are charged to expense as incurred.

Rent expense is recorded on a straight-line basis over the life of the respective lease. The difference between the cash payment and rent expense is recorded as deferred rent in either accounts payable and other accrued expenses or other long-term liabilities in the consolidated balance sheets, depending on when the amounts will be recognized. The Company receives incentives for tenant improvements on certain of its leases. The cash expended on such improvements is recorded as property and equipment and amortized over the life of the associated asset, or lease term, whichever is shorter. Incentives for tenant improvements are recorded as deferred rent in either accounts payable and other accrued expenses or other long-term liabilities in the consolidated balance sheets depending on when the amounts will be recognized. Incentives for tenant improvements are amortized on a straight-line basis over the lease term

Business Combinations

Business Combinations

The accounting for the Company’s 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. The Company has 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.

We have a contingent consideration arrangement in connection with a business acquisition which requires a fair value measurement determined using probability-weighted cash flows.

Intangible Assets

Intangible Assets

Intangible assets primarily consist of the Company's trade name, customer relationships, software and other amortizable intangible assets. The Company capitalizes the following costs associated with developing internal-use computer software pertaining to upgrades in our business and financial systems: (i) external direct costs of materials and services consumed in developing or obtaining internal-use computer software and (ii) certain payroll and payroll-related costs for Company employees who are directly associated with the development of internal-use software, to the extent of the time spent directly on the project. Customer relationships are generally amortized on an accelerated basis over the expected life based on projected future cash flows of approximately three to twelve years. Software purchased or developed for internal use is amortized over three to six years. The Company's trade name is not amortized, but is tested for impairment on at least an annual basis as of January 1 and more frequently if interim indicators of impairment exist. The trade name is considered to be impaired if the carrying value exceeds its estimated fair value. The Company used the relief from royalty method to estimate the fair value. The fair value of the asset is the present value of the license fees avoided by owning the asset, or the royalty savings.

Goodwill

Goodwill

The Company assesses goodwill for impairment on at least an annual basis on January 1 unless interim indicators of impairment exist. Goodwill is considered to be impaired when the net book value of a reporting unit exceeds its estimated fair value. The Company operates as a single operating segment and as a single reporting unit for the purpose of evaluating goodwill. As of January 1, 2019, the Company performed its annual impairment test of goodwill by comparing the fair value of the Company (based on market capitalization) to the carrying value of the Company's net equity, and concluded that the fair value of the reporting unit was significantly greater than the carrying amount.

Long-Lived Assets

Long-Lived Assets

The Company reviews its long-lived assets, including property and equipment and amortizable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. If the total of the expected undiscounted future net cash flows is less than the carrying amount of the asset, a loss is recognized for any excess of the carrying amount over the fair value of the asset.

Income Taxes

Income Taxes

The Company provides for income taxes as a “C” corporation on income earned from operations. The Company is subject to federal, state, and foreign taxation in various jurisdictions.

Deferred tax assets and liabilities are recorded to recognize the expected future tax benefits or costs of events that have been, or will be, reported in different years for financial statement purposes than for tax purposes. Deferred tax assets and liabilities are computed based on the difference between the consolidated financial statement carrying amount and tax basis of assets and liabilities using enacted tax rates and laws for the years in which these items are expected to reverse. If management determines that some portion or all of a deferred tax asset is not “more likely than not” to be realized, a valuation allowance is recorded as a component of the income tax provision to reduce the deferred tax asset to an appropriate level in that period. In determining the need for a valuation allowance, management considers all positive and negative evidence, including historical earnings, projected future taxable income, future reversals of existing taxable temporary differences, taxable income in prior carryback periods, and prudent, feasible tax-planning strategies.

The Company periodically assesses its tax positions for all periods open to examination by tax authorities based on the latest available information. Where it is not more likely than not that the Company’s tax position will be sustained, the Company records its best estimate of the resulting tax liability, penalties, and interest in the consolidated financial statements. These uncertain tax positions are recorded as a component of income tax expense. As uncertain tax positions in periods open to examination are closed out, or as new information becomes available, the resulting change is reflected in the recorded liability and income tax expense. Penalties and interest recognized related to the reserves for uncertain tax positions are recorded as a component of income tax expense.

Comprehensive Income

Comprehensive Income

Comprehensive income is the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, and is presented in the consolidated statements of comprehensive income.

Share-Based Payments

Share-Based Payments

Share-based payments to employees are recognized in the consolidated statements of operations based on their grant date fair values with the expense for time vested awards recognized on an accelerated basis over the vesting period. The expense for performance awards is recognized straight line over the vesting period. The Company uses the Black-Scholes option-pricing model to determine the fair value of its option awards at the time of grant.

Defined Benefit Plan and Other Postretirement Benefits

Defined Benefit Plan and Other Postretirement Benefits

The Company recognizes the underfunded status of defined benefit plans on the consolidated balance sheets within other long-term liabilities. Gains and losses, and prior service costs and credits that have not yet been recognized through net periodic benefit cost are recognized in accumulated other comprehensive income (loss), net of tax effects, and will be amortized as a component of net periodic cost in future periods. The measurement date, the date at which the benefit obligations are measured, is the Company’s fiscal year-end.

The Company also offers medical and dental benefits to inactive employees (and their eligible dependents) on long-term disability. The Company accrues the costs of the benefits at the date the inactive employee becomes disability eligible and elects to participate in the benefit. The accrued cost for such benefits is calculated using an actuarial estimate of the present value of all future benefit payments for obligations at the end of the fiscal year.

Self-Funded Medical Plans

Self-Funded Medical Plans

The Company maintains self-funded medical insurance. Self-funded plans include Consumer Driven Health Plans with a Health Savings Account option and traditional choice plans. Further, self-funded plans also include prescription drug and dental benefits. The Company records an incurred but unreported claim liability in the accrued compensation and benefits line of the consolidated balance sheets for self-funded plans based on an actuarial valuation. The estimate of the incurred but unreported claim liability was provided by a third-party valuation firm, primarily based on claims and participant data for the medical, dental, and pharmacy related costs.

Fair Value Measurements

Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, we consider the principal or most advantageous market in which the asset or liability would transact, and if necessary, consider assumptions that market participants would use when pricing the asset or liability.

The accounting guidance for fair value measurements establishes a three-level fair value hierarchy that prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3). Assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

Recently Adopted Accounting Standards and Recent Accounting Pronouncements Not Yet Adopted

Recent Accounting Pronouncements Not Yet Adopted

In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This guidance requires a customer in a cloud computing arrangement that is a service contract to follow existing internal-use software guidance to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 generally aligns the guidance on capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with that of implementation costs incurred to develop or obtain internal-use software, including hosting arrangements that include an internal-use software license. ASU 2018-15 is effective for interim reporting periods for fiscal years beginning after December 15, 2019. Early adoption is permitted. The standard may be adopted either retrospectively or prospectively. The Company is currently assessing the future impact of this update on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability of accounting for lease transactions. The new leasing standard requires lessees to recognize lease assets and lease liabilities on their balance sheet for all leases with a lease term of greater than 12 months. Lessor accounting is largely unchanged. Topic 842 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB provided an alternative transition method of adoption through ASU No. 2018-11, Targeted Improvements, which permits the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption. The Company will adopt the standard beginning in fiscal 2020 using the modified retrospective transition approach, specifically, using the alternative transition method provided by ASU 2018-11.

A dedicated implementation team has substantially completed its evaluation of the impact of the new standard. The Company's assessment efforts to date have included reviewing the provisions of Topic 842, gathering information to evaluate its lease population and portfolio, evaluating the nature of real and personal property and other arrangements that may meet the definition of a lease, designing and implementing one-time implementation controls as well as new post-adoption lease processes and controls, implementing a new lease accounting software solution, and evaluating certain accounting policy elections. As a result of our evaluation, the Company identified changes to and modified certain of our accounting policies and practices. While some modifications were complex to design and test, the effect of such changes are not expected to be significant upon adoption of Topic 842. The Company will elect certain practical expedients provided under Topic 842, including the option not to apply lease recognition for short–term leases; an election to not separate lease from non-lease components; and a package of practical expedients such that, upon the initial adoption of Topic 842, the Company will not reassess whether expired or existing contracts contain leases, nor will the Company reassess the lease classification for expired or existing leases.

The Company expects that upon adoption it will recognize a material right-of-use asset of approximately $270 million and a lease liability of approximately $330 million on the balance sheet, which is inclusive of required conforming balance sheet reclassifications. The Company does not expect the standard to have any other material impact on the consolidated financial statements or results of operations. Adoption of the standard is not expected to impact the Company’s ability to comply with the financial covenants as defined in the Credit Agreement discussed further in Note 12. The Company is continuing to refine its processes in order to meet the accounting and disclosure requirements upon adoption of Topic 842 in the first quarter of fiscal2020.

Other recent accounting pronouncements issued during fiscal 2019 and through the filing date are not expected to have a material impact on the Company's present or historical consolidated financial statements.

Recently Adopted Accounting Standards

In March 2019, the SEC issued its Final Rule Release No. 33-10618, FAST Act Modernization and Simplification of Regulation S-K. The guidance in this Release revises certain disclosure requirements in SEC Regulation S-K, with the intent of improving the readability of filed documents and simplifying registrants' compliance efforts. The Company adopted certain aspects of this Release in the fourth quarter of fiscal 2019 which did not have a material impact on the consolidated financial statements. Other aspects not yet adopted are still being evaluated but are not expected to be material.

The Company completed its assessment for the tax effects of the Tax Cuts and Jobs Act, or the 2017 Tax Act, under the guidance of Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, or SAB 118, during the third quarter of fiscal 2019. The Company recorded adjustments to previously recognized provisional estimates primarily related to the re-measurement effects on certain deferred tax balances. The completion of its assessment resulted in a reduction in the provision for income taxes during the third quarter of fiscal 2019. See Note 14 to the consolidated financial statements for further information regarding the impact of the 2017 Tax Act on fiscal 2019.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The amendments set forth certain presentation requirements, including that such analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed with all significant reconciling items described by appropriate captions with contributions from and distributions to owners shown separately. The amendments became effective on November 5, 2018 and did not have a material effect on the Company's consolidated financial statements for fiscal 2019. According to the SEC’s Questions and Answers of General Applicability Question 105.09 dated September 25, 2018 and updated October 4, 2018, the SEC would not object if the filer’s first presentation of the changes in stockholders’ equity is included in its Form 10-Q for the quarter that begins after the effective date of the amendments. The Company will first present such changes beginning with the first quarter of fiscal 2020.

In August 2018, the FASB issued ASU 2018-14, Compensation -Retirement Benefits -Defined Benefit Plans -General (Topic 715-20) - Disclosure Framework -Changes to the Disclosure Requirement for Defined Benefit Plans. This guidance is designed to improve the effectiveness of disclosures by removing and adding disclosures related to defined benefit plans. ASU 2018-14 is effective for reporting periods beginning after December 15, 2020 with early adoption permitted. In the fourth quarter of fiscal 2019 the Company early adopted this standard and adoption of this standard did not have a material impact on the consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. This guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Additionally, the guidance also expands an entity's ability to apply hedge accounting for nonfinancial and financial risk components, simplifies the hedge documentation and hedge effectiveness assessment requirements, and modifies certain disclosure requirements. ASU 2017-12 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. In the fourth quarter of fiscal 2019 the Company early adopted this standard using the modified retrospective approach. The adoption of this standard did not have a material impact on the consolidated financial statements.

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Codification No. 606, Revenue from Contracts with Customers (Topic 606). Topic 606, as amended, replaced existing revenue recognition standards by outlining a single set of comprehensive principles for recognizing revenue. The revenue standard also significantly expanded the disclosure requirements for revenue arrangements. Amendments to Topic 606 have generally focused on promoting a more consistent interpretation and application of the principles for recognizing revenue.

Topic 606 was effective for the Company beginning on April 1, 2018 (i.e., beginning with the first quarter fiscal 2019 interim financial statements). The Company adopted the new revenue standard using the full retrospective transition method, which requires that it be applied to each prior reporting period presented and that the cumulative effect of applying the standard be recognized at the earliest period presented (i.e., April 1, 2016, the beginning of the first quarter of fiscal 2017). During fiscal 2018, the Company completed its assessment of the cumulative effect of adopting Topic 606 and assessed the impact to be immaterial as of the date of adoption. The cumulative impact on our retained earnings for the earliest period presented of April 1, 2016 was an increase of $2.9 million. Thereafter, the adoption of Topic 606 increased our fiscal 2017 retained earnings by $8.4 million and decreased our fiscal 2018 retained earnings by $3.4 million, resulting in a cumulative impact on our retained earnings of$7.9 million as of April 1, 2018. The impact of Topic 606 on fiscal 2017 and 2018 results may not be representative of the impact on subsequent years’ results.

The Company also retrospectively adopted ASU 2017-07, which changed the presentation of net periodic benefit cost components on the condensed consolidated statement of operations. Under this guidance, the service cost component of net periodic benefit cost continues to be presented consistent with other employee compensation costs and within operating income, while the remaining components of net periodic benefit costs are excluded from operating income. As a result, net periodic benefit costs related to non-service components were reclassified to Other income (expense), net in the consolidated statement of operations for fiscal 2018 and 2017.

(1) The Company’s interest rate swaps are considered over-the-counter derivatives and fair value is estimated based on the present value of future cash flows using a model-derived valuation that uses Level 2 observable inputs such as interest rate yield curves. See Note 13 to our consolidated financial statements for further discussion on the Company’s derivative instruments designated as cash flow hedges.

(2) Investments in this category consist of primarily of mutual funds whose fair values are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. These assets represent investments held in a consolidated trust to fund the Company's non-qualified deferred compensation plan and are recorded in other long-term assets and other long-term liabilities on our consolidated balance sheets.

(3) The Company recognized a contingent consideration liability of 3.6 million in connection with the acquisition of Aquilent in fiscal 2017. As of March 31, 2019 and 2018, the estimated fair value of the contingent consideration liability was $1.2 million and $3.6 million, respectively, and was valued using probability-weighted cash flows, which is based on the use of Level 3 fair value measurement inputs. The fair value of the contingent consideration decreased by $2.4 million as the Company finalized the indemnification payments to the selling shareholders. During the third quarter of fiscal 2019, the Company recorded the decrease of payments in other income as a result of the fair value change and the liability is recorded in other long-term liabilities in the consolidated balance sheet.
