On August 16, 2016, a wholly-owned subsidiary of revenue for fiscal 2014 and fiscal 2013. The Corporate and Other segment in fiscal 2012 represented a negative

During fiscal 2016 and the last five fiscal years,11-month period ended January 1, 2016, we have completed 13 acquisitions, most notably:

Substantially allThe majority of our revenues are generated in the United States. Our totalconsolidated revenues are largely attributable to prime contracts or to subcontracts with other contractors engaged in work for the U.S. Government, with the remaining beingattributable to international customers, including the U.K. MoD and Australian Department of Defense, and customers across a variety of commercial markets. Within the U.S. Government, our revenues are diversified across many agencies, including various intelligence agencies, the U.S. Army, Navy and Air Force, DHS, FAA, TSA, the Defense Health Agency, NASA, NSF, the Environmental Protection Agency and research agencies like the Defense Advanced Research Projects Agency (DARPA), the DepartmentAgency.

We generated over 78%84%, 81% and 76% of our total revenues during each offiscal 2017, fiscal 2016 and the last three fiscal years11-month period ended January 1, 2016, respectively, from contracts with the U.S. Government (including all branches of the U.S. military), either as a prime contractor or a subcontractor to other contractors engaged in work for the U.S. Government. We generated more than 10% of our total revenues during each offiscal 2017, fiscal 2016 and the last three fiscal years11-month period ended January 1, 2016, from the U.S. Army. We expect to continue to derive most of our revenues from work performed under U.S. Government contracts. Our reputation and relationship with the U.S. Government, and in particular with the agencies of the DoD and the U.S. intelligence community,Intelligence Community, are key factors in maintaining and growing our revenues. Negative press reports or publicity, which could pertain to employee or subcontractor misconduct, conflicts of interest, poor contract performance, deficiencies in services, reports, products or other deliverables, information security breaches or other aspects of our business, regardless of accuracy, could harm our reputation, particularly with these agencies. If our reputation is negatively affected, or if we are suspended or debarred from contracting with government agencies for any reason, the amount of business with government and other customers would decrease and our future revenues and growth prospects would be adversely affected.

Revenues under contracts with the DoD, either as a prime contractor or subcontractor to other contractors, represented approximately 68%47% of our total revenues infor fiscal 2014.2017. Levels of DoD spending are difficult to predict and subject to significant risk. Our operating results could be adversely affected by spending caps or changes in the budgetary priorities of the U.S. Government or the DoD, as well as delays in program starts or the award of contracts or task orders under contracts. Current U.S. Government spending levels for defense-related programs may not be sustained and future spending and program authorizations may not increase or may decrease or shift to programs in areas in which we do not provide services or are less likely to be awarded contracts. Such changes in spending authorizations and budgetary priorities may occur as a result of the rapid growth ofuncertainty surrounding the federal budget, deficit, increasing political pressure and legislation, shifts in spending priorities from defense-related programs as a result of competing demands for federal funds, the number and intensity of military conflicts or other factors.

The U.S. Government also conducts periodic reviews of U.S. defense strategies and priorities, which may shift DoD budgetary priorities, reduce overall U.S. Government spending or delay contract or task order awards for defense-

The funding of U.S. Government programs is subject to an annual congressional budget authorization and appropriation process. In years when the U.S. Government does not complete its budget process before the end of its fiscal year on September 30, government operations are typically funded pursuant to a “continuing"continuing resolution,”" which allows federal government agencies to operate at spending levels approved in the previous budget cycle, but does not authorize new spending initiatives. When the U.S. Government operates under a continuing resolution, delays can occur in the procurement of the products, services and solutions that we provide and may result in new initiatives being canceled. We have from time to time experienced a decline in revenues in our fourth quarter ending January 31 and beyond as a result of this annual budget cycle, and we could experience similar declines in revenues from future delays in the budget process. In years whenWhen the U.S. Government fails to complete its budget process or to provide for a continuing resolution, a federal government shutdown may result. A federal government shutdown could, in turn, result in our incurrence of substantial labor or other costs without reimbursement under customer contracts, or the delay or cancellation of key programs or the delay of contract payments, which could have a negative effect on our cash flows and adversely affect our future 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.

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 customers and may impose added costs on our business. Some significant statutes and regulations that affect us include:

The FAR and many of our U.S. Government contracts contain organizational conflict of interest clauses that may limit our ability to compete for or perform certain other contracts or other types of services for particular customers. Organizational conflicts of interest arise when we engage in activities that may make us unable to render impartial assistance or advice to the U.S. Government, impair our objectivity in performing contract work or provide us with an unfair competitive advantage. A conflict of interest issue that precludes our competition for or performance on a significant program or contract could harm our prospects.

Our industry has experienced, and we expect it will continue to experience, significant changes to business practices as a result of an increased focus on affordability, efficiencies and recovery of costs, among other items. U.S. Government agencies may face restrictions or pressure regarding the type and amount of services that they may obtain from private contractors. Legislation, regulations and initiatives dealing with procurement reform, mitigation of potential conflicts of interest and environmental responsibility or sustainability, as well as any resulting shifts in the buying practices of U.S. Government agencies, such as increased usage of fixed price contracts, multiple award contracts and small business set-aside contracts, could have adverse effects on government

contractors, including us. Any of these changes could impair our ability to obtain new contracts or renew our existing contracts when those contracts are recompeted. Any new contracting requirements or procurement methods could be costly or administratively difficult for us to implement and could adversely affect our future revenues, profitability and prospects.

U.S. Government agencies, including the DCAA, DCMA and others, routinely audit and review a contractor’scontractor's performance on government contracts, indirect rates and pricing practices and compliance with applicable contracting and procurement laws, regulations and standards. They also review the adequacy of the contractor’s compliance with government standards for its business systems, including:including; a contractor’scontractor's accounting system, earned value management system, estimating system, materials management and accounting system, property management system and purchasing system.

Both contractors and the U.S. Government agencies conducting these audits and reviews have come under increased scrutiny. As a result, the current audits and reviews have become more rigorous and the standards to which we are held are being more strictly interpreted, increasing the likelihood of an audit or review resulting in an adverse outcome. During the course of its current audits, the DCAA is closely examining and questioning several of our long established and disclosed practices that it had previously audited and accepted, increasing the uncertainty as to the ultimate conclusion that will be reached.

A finding of significant control deficiencies in our system audits or other reviews can result in decremented billing rates to our U.S. Government customers until the control deficiencies are corrected and our remediations are accepted by DCMA. Government audits and reviews may conclude that our practices are not consistent with applicable laws and regulations and result in adjustments to contract costs and mandatory customer refunds. Such adjustments can be applied retroactively, which could result in significant customer refunds. Our receipt of adverse audit findings or the failure to obtain an “approved”"approved" determination of our various business systems from the responsible U.S. Government agency could significantly and adversely affect our business, including our ability to bid on new contracts and our competitive position in the bidding process. A determination of non-compliance with applicable contracting and procurement laws, regulations and standards could also result in the U.S. Government imposing penalties and sanctions against us, including withholding of payments, suspension of payments and increased government scrutiny that could delay or adversely affect our ability to invoice and receive timely payment on contracts, perform contracts or compete for contracts with the U.S. Government.

Our indirectIndirect cost audits by the DCAA remain open for fiscal 20082012 and subsequent fiscal years.years for Leidos Inc., and fiscal 2011 and subsequent fiscal years for Leidos Innovations. Although we have recorded contract revenues subsequent to fiscal 2008 based upon our estimate of costs that we believe will be approved upon final audit or review, we do not knowcannot predict the outcome of any ongoing or future audits or reviews and adjustments and, if future adjustments exceed our estimates, our profitability wouldmay be adversely affected.

We are routinely subject to governmental investigations relating to compliance with various laws and regulations with respect to our role as a contractor to federal, state and local government customers and in connection with performing services in countries outside the United States. If a review or investigation identifies improper or illegal activities, we may be subject to civil or criminal penalties or administrative sanctions, including the termination of contracts, forfeiture of profits, the triggering of price reduction clauses, suspension of payments, fines and suspension or debarment from doing business with governmental agencies. We may suffer harm to our reputation if allegations of impropriety are made against us, which would impair our ability to win new contract awards or receive contract renewals. Penalties and sanctions are not uncommon in our industry. If we incur a material penalty or administrative sanction or otherwise suffer harm to our reputation, our revenues, profitability, cash position and future prospects could be adversely affected. More generally, increases in scrutiny and investigations from government organizations, legislative bodies or agencies into business practices and into major programs supported by contractors may lead to increased legal costs and may harm our reputation, revenues, profitability and growth prospects.

Misconduct could include fraud or other improper activities such as falsifying time or other records and violations of laws, including the Anti-Kickback Act. Other examples could include the failure to comply with our policies and procedures or with federal, state or local government procurement regulations, regulations regarding the use and safeguarding of classified or other protected information, legislation regarding the pricing of labor and other costs in government contracts, laws and regulations relating to environmental, health or safety matters, bribery of foreign government officials, import-export control, lobbying or similar activities and any other applicable laws or regulations. Any data loss or information security lapses resulting in the compromise of personal information or the improper use or disclosure of sensitive or classified information could result in claims, remediation costs, regulatory sanctions against us, loss of current and future contracts and serious harm to our reputation. Although we have implemented policies, procedures and controls to prevent and detect these activities, these precautions may not prevent all misconduct, and as a result, we could face unknown risks or losses. Our failure to comply with applicable laws or regulations or misconduct by any of our employees, subcontractors, agents or business partners could damage our reputation and subject us to fines and penalties, restitution or other damages, loss of security clearance, loss of current and future customer contracts and suspension or debarment from contracting with federal, state or local government agencies, any of which would adversely affect our business, reputation and our future results.

We expect that a majority of the business that we seek in the foreseeable future will be awarded through a competitive bidding process. The U.S. Government has increasingly relied on contracts that are subject to a continuing competitive bidding process, including IDIQ, GSA Schedule and other multi-award contracts, which has resulted in greater competition and increased pricing pressure. The competitive bidding process involves substantial costs and a number of risks, including significant cost and managerial time to prepare bids and proposals for contracts that may not be awarded to us, or that may be awarded but for which we do not receive meaningful task orders, and to the risk of inaccurately estimating the resources and costs that will be required to fulfill any contract we win. Following contract award, we may encounter significant expense, delay, contract modifications or even contract loss as a result of our competitors protesting the award of contracts to us in competitive bidding. Any resulting loss or delay of start upstart-up and funding of work under protested contract awards may adversely affect our revenues and/or profitability. In addition, multi-award contracts require that we make sustained post-award efforts to obtain task orders under the contract. As a result, we may not be able to obtain these task orders or recognize revenues under these multi-award contracts. Our failure to compete effectively in this procurement environment would adversely affect our revenues and/or profitability.

Many of the U.S. Government programs in which we participate as a contractor or subcontractor extend for several years and include one or more base years and one or more option years. These programs are normally funded on an annual basis. Under our contracts, the U.S. Government generally has the right to not to exercise options to extend or expand our contracts and may otherwise terminate, cancel, modify or curtail our contracts at its convenience. Any decisions by the U.S. Government to not to exercise contract options or to terminate, cancel, modify or curtail our major programs or contracts would adversely affect our revenues, revenue growth and profitability.

We have experienced and continue to experience periodic performance issues under certain of our contracts. Some of our contracts involve the development of complex systems and products to achieve challenging customer goals in a competitive procurement environment. As a result, we sometimes experience technological or other performance difficulties, which have in the past and may in the future result in delays, cost overruns and failures in our performance of these contracts. If a government customer terminates a contract for default, we may be exposed to liability, including for excess costs incurred by the customer in procuring undelivered services and products from another source. Depending on the nature and value of the contract, a performance issue or termination for default could cause our actual results to differ from those anticipated and could harm our reputation.

Our business is highly competitive and we compete with larger companies that have greater name recognition, financial resources and a larger technical staffs.staff. We also compete with smaller, more specialized companies that are able to concentrate their resources on particular areas. Additionally, we compete with the U.S. Government’s own capabilities and federal non-profit contract research centers.

The markets in which we operate are characterized by rapidly changing technology and the needs of our customers change and evolve regularly. Accordingly, our success depends on our ability to develop services and products that address these changing needs and to provide people and technology needed to deliver these services and products. To remain competitive, we must consistently provide superior service, technology and performance on a cost-effective basis to our customers. Our competitors may be able to provide our customers with different or greater capabilities or technologies or better contract terms than we can provide, including technical qualifications, past contract experience, geographic presence, price and the availability of qualified professional personnel. In addition, our competitors may consolidate or establish teaming or other relationships among themselves or with third parties to increase their ability to address customers’ needs. Accordingly, we anticipate that larger or new competitors or alliances among competitors may emerge, which may adversely affect our ability to compete.

Our business involves the development of tailored services and solutions for our customers, a process that relies heavily upon the expertise and services of our employees. Our continued success depends on our ability to recruit and retain highly trained and skilled engineering, technical and professional personnel. Competition for skilled personnel is intense and competitors aggressively recruit key employees. In addition, many U.S. Government programs require contractors to have security clearances. Depending on the level of required clearance, security clearances can be difficult and time-consuming to obtain and personnel with security clearances are in great demand. Particularly in highly specialized areas, it has become more difficult to retain employees and meet all of our needs for employees in a timely manner, which may affect our growth. Although we intend to continue to devote significant resources to recruit, train and retain qualified employees, we may not be able to attract, effectively train and retain these employees. Any failure to do so could impair our ability to perform our contractual obligations efficiently and timely meet our customers’ needs and win new business, which could adversely affect our future results. Additionally, we recently completed the relocation of our corporate functions and the spin-off of our former technical, engineering, and enterprise information technology services business into a separate company, which resulted in higher than typical employee turnover and the transfer of personnel to the spin-off company. While we have hired and are training replacement personnel, there is little redundancy or overlap of responsibilities in our corporate functions

In addition to attracting and retaining qualified engineering, technical and professional personnel, we believe that our success will also depend on the continued employment of a highly qualified and experienced senior management team and its ability to retain existing business and generate new business. Our senior management team is important to our business because personal reputations and individual business relationships are a critical element of retaining and obtaining customer contracts in our industry, particularly with agencies performing classified operations. In February 2014, we announced that our Chief Executive Officer plans to retire upon the appointment of his successor and that we have initiated a process to identify our next Chief Executive Officer. We have also recently undergone other changes in our senior management team. These changes in key management could create uncertainty among our employees, customers and other third parties with which we do business. In addition, we could be adversely affected if we fail to adequately plan for the succession of members of our senior management team. OurAn inability to retain appropriately qualified and experienced senior executives could cause us to lose customers or new business opportunities.

As of January 31, 2014,December 29, 2017, our total backlog was $9$17.5 billion, including $3$5.0 billion in funded backlog. Due to the U.S. Government’sGovernment's ability to not exercise contract options or to terminate, modify or curtail our programs or contracts and the rights of our non-U.S. Government customers to cancel contracts and purchase orders in certain circumstances, we may realize less than expected or in some casesmay never realize revenues from some of the contracts that

are included in our backlog. Our unfunded backlog, in particular, contains management’s estimate of amounts expected to be realized on unfunded contract work that may never be realized as revenues. If we fail to realize as revenues amounts included in our backlog, our future revenues, profitability and growth prospects could be adversely affected.

We generate revenues under various types of contracts, which include cost reimbursement,cost-reimbursement, FP-IF, T&M, FP-LOE and FFP contracts. Our earnings and profitability may vary materially depending on changes in the proportionate amount of revenues derived from each type of contract, the nature of services or products provided, as well as the achievement of performance objectives and the stage of performance at which the right to receive fees, particularly under incentive and award fee contracts, is finally determined. Cost reimbursementCost-reimbursement and T&M contracts are generally less profitable than FFP contracts. Our operating results in any period may also be affected, positively or negatively, by customer’scustomers' variable purchasing patterns of our more profitable proprietary products.

Our profitability is adversely affected when we incur contract costs that we cannot bill to our customers. To varying degrees, each of our contract types involves some risk that we could underestimate the costs and resources necessary to fulfill the contract. While FFP contracts allow us to benefit from cost savings, these contracts also increase our exposure to the risk of cost overruns. Revenues from FFP contracts represented approximately 27%28% of our total revenues for fiscal 2014.2017. When making proposals on these types of contracts, we rely heavily on our estimates of costs and timing to complete the associated projects, as well as assumptions regarding technical issues. In each case, our failure to accurately estimate costs or the resources and technology needed to perform our contracts or to effectively manage and control our costs during performance could result, and in some instances has resulted, in reduced profits or in losses. More generally, any increased or unexpected costs or unanticipated delays in the performance of our contracts, including costs and delays caused by contractual disputes or other factors outside of our control, such as performance failures of our subcontractors, natural disasters or other force majeure events, could make our contracts less profitable than expected or unprofitable.

Revenues from our contracts are primarily recognized using the percentage-of-completion method or on the basis of partial performance towards completion. These methodologies require estimates of total costs at completion, fees earned on the contract, or both. This estimation process, particularly due to the technical nature of the services performed and the long-term nature of certain contracts, is complex and involves significant judgment. Adjustments

We are subject to a number of lawsuits and claims described in “Legal Proceedings”"Legal Proceedings" in Part I of this Annual Report on Form 10-K, as may be updated in our future filings with the SEC, including our Quarterly Reports on Form 10-Q. We are also subject to, and may become a party to, a variety of other litigation or claims and suits that arise from time to time in the ordinary course of our business. Adverse judgments or settlements in some or all of these legal disputes may result in significant monetary damages, penalties or injunctive relief against us. Any claims or litigation could be costly to defend, and even if we are successful or if fully indemnified or insured, could damage our reputation and make it more difficult to compete effectively or obtain adequate insurance in the future. Litigation and other claims, including those described in “Legal"Legal Proceedings,”" are subject to inherent uncertainties and management’s view of these matters may change in the future.

We are subject to numerous federal, state and foreign legal requirements on matters as diverse as data privacy and protection, employment and labor relations, immigration, taxation, anticorruption, import/export controls, trade restrictions, internal and disclosure control obligations, securities regulation and anti-competition. Compliance with diverse and changing legal requirements is costly, time-consuming and requires significant resources. For example, the SEC’s adoption of a new rule requiring certain disclosures about “conflict minerals” in certain products may impact our procurement practices and increase our costs. We are also focused on expanding ourconduct business in certain identified growth areas, such as health information technology, energy and environment,environmental services, which are highly regulated and may expose us to increased compliance risk. Violations of one or more of these diverse legal requirements in the conduct of our business could result in significant fines and other damages, criminal sanctions against us or our officers, prohibitions on doing business and damage to our reputation. Violations of these regulations or contractual obligations related to regulatory compliance in connection with the performance of customer contracts could also result in liability for significant monetary damages, fines and/or criminal prosecution, unfavorable publicity and other reputational damage, restrictions on our ability to compete for certain work and allegations by our customers that we have not performed our contractual obligations.

As a U.S. Government contractor and a provider of information technology services operating in multiple regulated industries and geographies, we handle sensitive information. Therefore, we are continuously exposed to cyber attacks and other security threats, including physical break-ins. Any electronic or physical break-in or other security breach or compromise may jeopardize security of information stored or transmitted through our information technology systems and networks. This could lead to disruptions in mission-critical systems, unauthorized release of confidential or otherwise protected information and corruption of data. Although we have implemented policies, procedures and controls to protect against, detect and mitigate these threats, we face advanced and persistent attacks on our information systems and attempts by others to gain unauthorized access to our information technology systems are becoming more sophisticated. These attempts include covertly introducing malware to our computers and networks and impersonating authorized users, among others, and may be perpetrated by well-funded organized crime or state sponsored efforts. We seek to detect and investigate all security incidents and to prevent their occurrence or recurrence. We continue to invest in and improve our threat protection, detection and mitigation policies, procedures and controls. In addition, we work with other companies in the industry and government participants on increased awareness and enhanced protections against cybersecurity threats. However, because of the evolving nature and sophistication of these security threats, which can be difficult to detect, there can be no assurance that our policies, procedures and controls have or will detect or prevent any of these threats and we cannot predict the full impact of any such past or future incident. We may experience similar security threats to the information technology systems that we develop, install or maintain under customer contracts. Although we work cooperatively with our customers and other business partners to seek to minimize the impactsimpact of cyber and other security threats, we must rely on the safeguards put in place by those entities. Any remedial costs or other liabilities related to cyber or other security threats may not be fully insured or indemnified by other means. Occurrence of any of these security threats could expose us to claims, contract terminations and damages and could adversely affect our reputation, ability to work on sensitive U.S. Government contracts, business operations and financial results.

Any system or service disruptions, including those caused by ongoing projects to improve our information technology systems and the delivery of services, whether through our shared services organization or outsourced services, if not anticipated and appropriately mitigated, could have a material adverse effect on our business including, among other things, an adverse effect on our ability to bill our customers for work performed on our contracts, collect the amounts that have been billed and produce accurate financial statements in a timely manner. We are also subject to systems failures, including network, software or hardware failures, whether caused by us, third-party service providers, cybersecurity threats, natural disasters, power shortages, terrorist attacks or other events, which could cause loss of data and interruptions or delays in our business, cause us to incur remediation costs, subject us to claims and damage our reputation. In addition, the failure or disruption of our communications could cause us to interrupt or suspend our operations or otherwise adversely affect our business. Our property and

business interruption insurance may be inadequate to compensate us for all losses that may occur as a result of any system or operational failure or disruption and, as a result, our future results could be adversely affected.

Many of the systems and networks that we develop, install and maintain for our customers involve managing and protecting personal information and information relating to national security and other sensitive government functions. While we have programs designed to comply with relevant privacy and security laws and restrictions, if a system or network that we develop, install or maintain were to fail or experience a security breach or service interruption, whether caused by us, third-party service providers, cybersecurity threats or other events, we may experience loss of revenue, remediation costs or face claims for damages or contract termination. Any such event could cause serious harm to our reputation and prevent us from having access to or being eligible for further work on such systems and networks. Our errors and omissions liability insurance may be inadequate to compensate us for all of the damages that we may incur and, as a result, our future results could be adversely affected.

We design and develop technologically advanced and innovative products and services applied by our customers in a variety of environments. Problems and delays in development or delivery as a result of issues with respect to design, technology, licensing and patent rights, labor, learning curve assumptions or materials and components could prevent us from achieving contractual requirements.

In addition, our offerings cannot be tested and proven in all situations and are otherwise subject to unforeseen problems that could negatively affect revenue and profitability such as problems with quality and workmanship, country of origin, delivery of subcontractor components or services and unplanned degradation of product performance. Among the factors that may affect revenue and profits could be unforeseen costs and expenses not covered by insurance or indemnification from the customer, diversion of management focus in responding to unforeseen problems, loss of follow-on work, and, in the case of certain contracts, repayment to the government customer of contract cost and fee payments we previously received.

We derive a portion of our revenues from programs with the U.S. Government that are subject to security restrictions (classified programs), which preclude the dissemination of information that is classified for national security purposes. We are limited in our ability to provide information about these classified programs, their risks or any disputes or claims relating to such programs. As a result, investors have less insight into our classified programs than our other businesses and therefore less ability to fully evaluate the risks related to our classified business.

We selectively pursue strategic acquisitions, investments and joint ventures. These transactions require significant investment of time and resources and may disrupt our business and distract our management from other responsibilities. Even if successful, these transactions could reduce earnings for a number of reasons, including the amortization of intangible assets, impairment charges, acquired operations that are not yet profitable or the payment of additional consideration under earn-out arrangements if an acquisition performs better than expected. Acquisitions, investments and joint ventures pose many other risks that could adversely affect our reputation, operations or financial results, including:

If our acquisitions, investments or joint ventures fail, perform poorly or their value is otherwise impaired for any reason, including contractions in credit markets and global economic conditions, our business and financial results could be adversely affected.

In addition, we periodically 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 would adversely affect our financial results.

Intangible assets with indefinite lives, including goodwill, are tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Intangible assets with finite lives are assessed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Examples of events or changes in circumstances indicating that the carrying value of intangible assets may not be recoverable could include a significant adverse change in legal factors or in the business climate, an adverse action or assessment by a regulator, unanticipated competition, loss of key personnel, or a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or otherwise disposed. We face continued uncertainty in our business environment due to the substantial fiscal and economic challenges facing the U.S. Government, our primary customer, as well as challenges in the commercial healthcare industry, compounded by lower levels of U.S. Government reimbursements, including reductions in Medicare reimbursements which in turn impact hospital IT spending. Adverse changes in fiscal and economic conditions, such as the manner in which the budget cuts are implemented, including sequestration, and issues related to the nation’s debt ceiling, could adversely impact our future revenues and profitability. These circumstances could result in an impairment of goodwill and/or other intangibles. Also, adverse equity market conditions that result in a decline in market multiples and our stock price could result in an impairment of goodwill and/or other intangibles. Any future impairment of goodwill or other intangible assets would have a negative impact on our profitability and financial results.

We rely on our teaming relationships with other prime contractors and subcontractors, who are also often our competitors in other contexts, in order to submit bids for large procurements or other opportunities where we believe the combination of services and products provided by us and the other companies will help us to win and perform

the contract. Our future revenues and growth prospects could be adversely affected if other contractors eliminate or reduce their contract relationships with us, or if the U.S. Government terminates or reduces these other contractors’ programs, does not award them new contracts or refuses to pay under a contract. Companies that do not have access to U.S. Government contracts may perform services as our subcontractor and that exposure could enhance such companies’ prospect of securing a future position as a prime U.S. Government contractor which could increase competition for future contracts and impair our ability to perform on contracts.

We may have disputes with our subcontractors arising from, among other things, the quality and timeliness of work performed by the subcontractor, customer concerns about the subcontractor, our failure to extend existing task orders or issue new task orders under a subcontract, our hiring of a subcontractor’s personnel or the subcontractor’s failure to comply with applicable law. Uncertain economic conditions heighten the risk of financial stress of our subcontractors, which could adversely impact their ability to meet their contractual requirements to us. If any of our subcontractors fail to timely meet their contractual obligations or have regulatory compliance or other problems, our ability to fulfill our obligations as a prime contractor or higher tier subcontractor may be jeopardized. Significant losses could arise in future periods and subcontractor performance deficiencies could result in our termination for default. A termination for default could eliminate a revenue source, expose us to liability and have an adverse effect on our ability to compete for future contracts and task orders, especially if the customer is an agency of the U.S. Government.

Some of our services and operations involve the assessment or remediation of environmental hazards, as well as the use, handling or disposal of hazardous substances. These activities and our operations generally subject us to extensive foreign, federal, state and local environmental protection and health and safety laws and regulations, which, among other things, require us to incur costs to comply with these regulations and could impose liability on us for handling or disposing of hazardous substances. Furthermore, failure to comply with these environmental protection and health and safety laws and regulations could result in civil, criminal, regulatory, administrative or contractual sanctions, including fines, penalties or suspension or debarment from contracting with the U.S. Government. Our current and previous ownership and operation of real property also subjects us to environmental protection laws, some of which hold current or previous owners or operators of businesses and real property liable for hazardous substance releases, even if they did not know of and were not responsible for the releases. If we have any violations of, or incur liabilities pursuant to these laws or regulations, our financial condition and operating results could be adversely affected.

We design, develop, manufacture, sell, service and maintain various inspection systems that are designed to assist in the detection of bombs, explosives, weapons, contraband or other threats. In some instances, we also train operators of such systems. Many of these systems utilize software algorithms that are probabilistic in nature and subject to significant technical limitations. Many of these systems are also dependent on the performance of their operators. There are many factors, some of which are beyond our control, which could result in the failure of our products to help detect the presence of bombs, explosives, weapons, contraband or other threats. Some of these factors could include operator error, inherent limitations in our systems, and misuse or malfunction of our systems. The failure of our systems to help detect the presence of any of these dangerous materials could lead to injury, death and extensive property damage and may lead to product liability, professional liability, or other claims against us. Further, if our systems fail to, or are perceived to have failed to help detect a threat, the negative publicity from such incident could have a material adverse effect on our business.

We maintain insurance coverage with third-party insurers as part of our overall risk management strategy and because some of our contracts require us to maintain specific insurance coverage limits. However, not every risk or liability is or can be protected by insurance, and, for those risks we insure, the limits of coverage we purchase or that are reasonably obtainable in the market may not be sufficient to cover all actual losses or liabilities incurred. If any of our third-party insurers fail, cancel our coverage or otherwise are unable to provide us with adequate insurance coverage, then our overall risk exposure and our operational expenses would increase and the

significant product and other liability claims or losses. Moreover, there is a risk that commercially available liability insurance will not continue to be available to us at a reasonable cost, if at all. If liability claims or losses exceed our current or available insurance coverage, our business, financial position, operating results and prospects may be harmed. Regardless of the adequacy of our liability insurance coverages, any significant claim may have an adverse effect on our industry and market reputation, leading to a substantial decrease in demand for our products and services and reduced revenues.

Our international business operations may be subject to additional and different risks than our U.S. business. Failure to comply with U.S. Government and foreign laws and regulations applicable to international business, such as the Foreign Corrupt Practices Act or U.S. export control regulations, could have an adverse impact on our business with the U.S. Government and could expose us to administrative, civil or criminal penalties. Additionally, these risks relating to international operations may expose us to potentially significant contract losses.

In some countries, there is an increased chance for economic, legal or political changes that may adversely affect the performance of our services, sale of our products or repatriation of our profits. International transactions can also involve increased financial and legal risks arising from foreign exchange rate variability, imposition of tariffs or additional taxes, restrictive trade policies, any delay or failure to collect amounts due to us and differing legal systems. We provide services and products in support of U.S. Government customers in countries with governments that may be or may become unstable, which increases the risk of an incident resulting in injury or loss of life, or damage or destruction of property or inability to meet our contractual obligations. Although our international operations have historically generated a small proportion of our revenues, we do not know the impact thatare seeking to grow our international business, in which case these regulatory, geopolitical and other factors may have a greater impact on our business in the future and any of these factors could adversely affect our business.

We rely principally on trade secrets to protect much of our intellectual property in cases where we do not believe that patent protection is appropriate or obtainable. However, trade secrets are 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. We may be unable to detect unauthorized use of our intellectual property or otherwise take appropriate steps to enforce our rights. Failure to obtain or maintain trade secret protection could adversely affect our competitive business position. If we are unable to prevent third parties from infringing or misappropriating our copyrights, trademarks or other proprietary information, our competitive position could be adversely affected. In addition, in connection with the performance of services, the U.S. Government has certain rights to inventions, data, software codes and related material that we develop under government-funded contracts and subcontracts, which means that U.S. Government may disclose or license our information to third parties, including, in some instances, our competitors.

In the course of conducting our business, we may inadvertently infringe the intellectual property rights of others, resulting in claims against us or our customers. Our contracts generally indemnify our customers for third-party claims for intellectual property infringement by the services and products we provide. The expense of defending these claims may adversely affect our financial results.

Our financial results may fluctuate as a result of a number of factors, many of which are outside of our control. For these reasons, comparing our operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance. Our financial results may be negatively affected by any of the risk factors listed in this “Risk Factors”"Risk Factors" section and other matters described elsewhere in this Annual Report on Form 10-K.

Accounting for many of our programs requires judgment relative to assessing risks, including risks associated with estimating directed delays and reductions in scheduled deliveries, unfavorable resolutions of claims and contractual

matters, judgments associated with estimating contract revenues and costs, and assumptions for schedule and technical issues. Due to the size and nature of many of our contracts, the estimation of total revenues and cost at completion is complicated and subject to many variables. For example, we must make assumptions regarding the length of time to complete the contract because costs also include expected increases in wages and prices for materials, consider whether the intent of entering into multiple contracts was effectively to enter into a single project in order to determine whether such contracts should be combined or segmented, consider incentives or penalties related to performance on contracts in estimating revenue and profit rates, and record them when there is sufficient information for us to assess anticipated performance; and use estimates of award fees in estimating revenue and profit rates based on actual and anticipated awards. Because of the significance of the judgments and estimation processes involved in accounting for construction and production type contracts, materially different amounts could be recorded if we used different assumptions or if the underlying circumstances were to change. Changes in underlying assumptions, circumstances or estimates may adversely affect our future results of operations and financial condition.

In March 2012, our boardBoard of directorsDirectors approved the initiation of a quarterly dividend program. The timing, declaration, amount and payment of any future dividends fall within the discretion of our boardBoard of directorsDirectors and will depend on many factors, including our available cash, estimated cash needs, earnings, financial condition, operating results, capital requirements, as well as limitations in our contractual agreements, applicable law, regulatory constraints, industry practice and other business considerations that our boardBoard of directorsDirectors considers relevant. A change in our dividend program could have an adverse effect on the market price of our common stock.

Some provisions of our certificate of incorporation and bylaws may have the effect of delaying, discouraging or preventing a merger or acquisition that our stockholders may consider favorable, including transactions in which stockholders might receive a premium for their shares. These restrictions, which may also make it more difficult for our stockholders to elect directors not endorsed by our current directors and management, include the following:

As a Delaware corporation, we are also subject to certain restrictions on business combinations. Under Delaware law, a corporation may not engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years, or among other things, our boardBoard of directorsDirectors has approved the business combination or the transaction pursuant to which such person became a 15% holder prior to the time the person became a 15% holder.

This Annual Report on Form 10-K contains forward-looking statements that are based on our management’s belief and assumptions about the future in light of information currently available to our management. In some cases, you can identify forward-looking statements by words such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “continue,”"may," "will," "should," "expects," "intends," "plans," "anticipates," "believes," "estimates," "predicts," "potential," "continue," and similar words or phrases or the negative of these words or phrases. These statements relate to future events or our future financial performance, and involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements. These statements may include statements regarding the benefits and synergies of the Transactions and future opportunities for the combined company following the transaction. Although we believe that the expectations reflected in the forward-looking statements are reasonable when made, we cannot guarantee future results, levels of activity, performance or achievements. There are a number of important factors that could cause our actual results to differ materially from those results anticipated by our forward-looking statements, which include, but are not limited to:

We do not undertake any obligation to update or revise any of the forward-looking statements to reflect events, circumstances, changes in expectations, or the occurrence of unanticipated events after the date of those statements or to conform these statements to actual results.
