NORTHROP GRUMMAN CORPORATION                        

PART I
Item 1. Business
HISTORY AND ORGANIZATION
History
Northrop Grumman Corporation (herein referred to as “Northrop Grumman,” the “company,” “we,” “us,” or “our”) is a leading global security company providing innovative systems, products and solutions in unmanned systems, cybersecurity; command, control, communications and computers (C4) intelligence, surveillance, and reconnaissance (C4ISR); and logistics and modernization to government and commercial customers worldwide through our four sectors: Aerospace Systems, Electronic Systems, Information Systems and Technical Services. We participate in many high-priority defense and government services programs in the United States (U.S.) and abroad. We offer a broad portfolio of capabilities and technologies that enable us to deliver innovative systems and solutions for applications that range from undersea to outer space and into cyberspace. We conduct most of our business with the U.S. Government, principally the Department of Defense (DoD) and intelligence community. We also conduct business with local, state, and foreign governments and domestic and international commercial customers. For a discussion of risks associated with our operations, see Risk Factors in Part I, Item 1A.
The company originally was formed in Hawthorne, California in 1939 as Northrop Aircraft Incorporated and was reincorporated in Delaware in 1985 as Northrop Corporation. Northrop Aircraft Incorporated was a principal developer of the flying wing technology, including the B-2 Stealth Bomber. The company developed into one of the largest defense contractors in the world through a series of acquisitions, as well as organic growth. Some of the most notable acquisitions during the last two decades included the acquisition of Grumman Corporation (Grumman) in 1994, after which time the company was renamed Northrop Grumman Corporation. Grumman was a premier military aircraft systems integrator and builder of the Lunar Module that first delivered men to the surface of the moon. In 1996, we acquired the defense and electronics businesses of Westinghouse Electric Corporation (Westinghouse), a world leader in the development and production of sophisticated radar and other electronic systems for the nation’s defense, civil aviation, and other international and domestic applications. In 2001, we acquired Litton Industries, a global electronics and information technology company, and one of the nation’s leading full-service design, engineering, construction, and life cycle supporters of major surface ships for the U.S. Navy, U.S. Coast Guard, and international navies. In 2002, we acquired TRW Inc. (TRW), a leading developer of military and civil space systems and satellite payloads, as well as a leading global integrator of complex, mission-enabling systems and services.
Effective as of March 31, 2011, the company completed the spin-off to its shareholders of Huntington Ingalls Industries, Inc. (HII). HII operates our former Shipbuilding business, which was acquired in 2001 through the acquisition of Newport News Shipbuilding and a portion of the Litton acquisition. The spin-off was the culmination of the company’s decision to explore strategic alternatives for Shipbuilding, as it was determined to be in the best interests of shareholders, customers, and employees by allowing the company and Shipbuilding to pursue more effectively their respective opportunities to maximize value. As a result of the spin-off, assets, liabilities and results of operations for the former Shipbuilding segment have been reclassified as discontinued operations for all periods presented. See Note 3 to our consolidated financial statements in Part II, Item 8 for further information.
Organization
From time to time, we acquire or dispose of businesses, and realign contracts, programs or business areas among and within our operating segments that possess similar customers, expertise, and capabilities. Internal realignments are designed to more fully leverage existing capabilities and enhance development and delivery of products and services. The operating results for all periods presented have been revised to reflect these changes made through December 31, 2012. We are currently aligned into four operating segments: Aerospace Systems, Electronic Systems, Information Systems, and Technical Services. See Note 4 to our consolidated financial statements in Part II, Item 8 for further information.

SELECTED FINANCIAL DATA AND SEGMENT OPERATING RESULTS
For a more complete understanding of our business, see Selected Financial Data in Part II, Item 6. For a more complete understanding of our segment financial information, see Segment Operating Results in Part II, Item 7, and Note 4 to the consolidated financial statements in Part II, Item 8.
CUSTOMER CONCENTRATION
Our primary customer is the U.S. Government. Revenue from the U.S. Government (which includes foreign military sales – a method to sell U.S. defense equipment and services to foreign governments through the DoD) accounted for 90 percent or more of total revenues in each of the years ended December 31, 2012, 2011 and 2010. No single product or service accounted for more than ten percent of total revenue during any period presented. See Risk Factors in Part I, Item 1A.
COMPETITIVE CONDITIONS
We compete with many companies in the defense industry and the intelligence and civil markets. Lockheed Martin Corporation, The Boeing Company, Raytheon Company, General Dynamics Corporation, L-3 Communications Corporation, SAIC, BAE Systems Inc., EADS, and Finmeccanica SpA are our primary competitors. Key characteristics of our industry include long operating cycles and intense competition, which is evident through the number of bid protests (competitor protests of U.S. government procurement awards) and the number of competitors bidding on program opportunities.
It is common in the defense industry for work on major programs to be shared among a number of companies. A company competing to be a prime contractor may, upon ultimate award of the contract to another competitor, become a subcontractor for the ultimate prime contracting company. It is not unusual to compete for a contract award with a peer company and, simultaneously, perform as a supplier to or a customer of that same competitor on other contracts, or vice versa.
SEASONALITY
No material portion of our business is considered to be seasonal.
BACKLOG
Total backlog includes both funded backlog (firm orders for which funding is contractually obligated by the customer) and unfunded backlog. Unexercised contract options and indefinite delivery indefinite quantity (IDIQ) contracts are not included in backlog, until the time the option or IDIQ task order is exercised or awarded. For multi-year service contracts with non-U.S. Government customers having no stated contract values, backlog includes only the amounts committed by the customer. Backlog is converted into sales as costs are incurred or deliveries are made. At December 31, 2012, total backlog was $40.8 billion, compared with $39.5 billion at the end of 2011. Approximately $21.4 billion of our backlog at December 31, 2012, is expected to be converted into sales in 2013. For backlog by segment, see Backlog in Part II, Item 7.
RESEARCH AND DEVELOPMENT
Our research and development activities primarily include independent research and development (IR&D) efforts related to U.S. Government programs. Company-sponsored IR&D efforts are included in general and administrative expenses and are generally allocated to U.S. Government contracts, while customer-sponsored research and development efforts are charged directly to the related contracts. Company-sponsored IR&D expenses totaled $520 million, $543 million, and $580 million in 2012, 2011, and 2010, respectively.
PATENTS
We routinely apply for and own a number of U.S. and foreign patents related to the products and services we provide. In addition to owning a large portfolio of proprietary intellectual property, we license some intellectual

4

Table of Contents

NORTHROP GRUMMAN CORPORATION

property rights to and from third parties. The U.S. Government generally holds licenses to patents developed in the performance of U.S. Government contracts, and may use or authorize others to use the inventions covered by these patents. Although these intellectual property rights are important to the operation of our business, no existing patent, license or other intellectual property right is of such importance that its loss or termination would, in our opinion, have a material impact on our business. See Risk Factors in Part I, Item 1A.
RAW MATERIALS
We have not experienced significant delays in the supply or availability of raw materials, nor have we experienced a significant price increase for raw materials, that would have a notable adverse effect on the company's consolidated financial position, results of operations, or cash flows. See Risk Factors in Part I, Item 1A and Overview – Outlook in Part II, Item 7.
EMPLOYEE RELATIONS
We believe that we maintain good relations with our 68,100 employees, of which approximately 3,300 are covered by 17 collective bargaining agreements. We negotiated or re-negotiated eight of our collective bargaining agreements in 2012 and expect to re-negotiate renewals for three of our collective bargaining agreements in 2013. These negotiations had no material adverse effect on our results of operations. For risks associated with collective bargaining agreements, see Risk Factors in Part I, Item 1A.
REGULATORY MATTERS
Government Contract Regulation
Our businesses are affected by numerous laws and regulations, including those relating to the award, administration and performance of U.S. Government contracts. The U.S. Government generally has the ability to terminate our contracts, in whole or in part, without prior notice, for convenience or for default based on performance. If a U.S. Government contract were to be terminated for convenience, we generally would be protected by provisions covering reimbursement for costs incurred on the contract and profit on those costs, but not the anticipated profit that would have been earned had the contract been completed. In the unusual circumstance where a U.S. Government contract does not have such termination protection, we attempt to mitigate the termination risk through other means. Termination resulting from our default may expose us to liability and could have a material adverse effect on our ability to compete for other contracts. The U.S. Government also has the ability to stop work under a contract for a limited period of time for its convenience. In the event of a stop work order, we generally would be protected by provisions covering reimbursement for costs incurred on the contract to date and for costs associated with the temporary stoppage of work on the contract. However, such temporary stoppages and delays could introduce inefficiencies for which we may not be able to negotiate full recovery from the U.S. Government, and could ultimately result in termination for convenience or reduced future orders on certain contracts. Additionally, we may be required to continue to perform for some period of time on certain of our U.S. Government contracts, even if the U.S. Government is unable to make timely payments. See Risk Factors in Part I, Item 1A.
Certain programs with the U.S. Government that are prohibited by the customer from being publicly discussed in detail are referred to as “restricted” in this Form 10-K. The consolidated financial statements and financial information in this Form 10-K reflect the operating results of our entire company, including such restricted programs under accounting principles generally accepted in the United States of America (GAAP).
Contracts
We generate the majority of our business from long-term contracts with the U.S. Government for development, production, and support activities. Due to the long-term nature of our contracts with the U.S. Government and the products and services covered by these contracts, we generally recognize revenue on the percentage of completion method of accounting. Under the percentage of completion method of accounting, revenues are generally recognized as costs are incurred (cost-to-cost method) or as units are delivered (units-of-delivery method). Unless otherwise specified in a contract, allowable and allocable costs are billed to contracts with the U.S. Government under the requirements of the Federal Acquisition Regulation (FAR) and Cost Accounting Standards (CAS) regulations. Examples of costs incurred by us and not billed to the U.S. Government in accordance with the requirements of the FAR and CAS regulations include, but are not limited to, certain legal costs, lobbying costs, charitable donations, advertising costs and interest expense. Our long-term contracts typically fall into one of two broad categories:
Cost-type contracts – Cost-type contracts include cost plus fixed fee, award fee, and incentive fee contracts. Cost-type contracts provide for reimbursement of the contractor’s allowable costs incurred plus a fee. Cost-type contracts generally require that the contractor use its best efforts to accomplish the scope of the work within some specified time and some stated dollar limitation. Fees on cost-type contracts can be fixed in terms of dollar value or

NORTHROP GRUMMAN CORPORATION

percentage of costs. Award fees are based on performance criteria such as cost, schedule, quality, and technical performance. Award fees are determined and earned based on an evaluation by the customer of the company's performance against negotiated criteria, and are intended to provide motivation for excellence in contract performance. Incentive fees provide for an initially negotiated fee to be adjusted later by a formula based on the relationship of total allowable costs to total target costs. Award fees and incentive fees that can reasonably be estimated and are deemed reasonably assured are recorded over the performance period of the contract.
Fixed-price contracts – A firm fixed-price contract is a contract in which the specified scope of work is agreed to for a price that is a pre-determined, negotiated amount and not generally subject to adjustment regardless of costs incurred by the contractor, absent changes in scope by the customer. Fixed-price incentive contracts provide for reimbursement of the contractor’s allowable costs plus a fee up to a ceiling amount, but are subject to a cost-share limit that affects profitability. Fixed-price incentive contracts effectively become firm fixed-price contracts once the cost-share limit is reached. Time-and-materials contracts are considered fixed-price contracts as they specify a fixed hourly rate for each labor hour charged.

Profit margins may vary materially depending on, among other things, the negotiated contract fee arrangements, 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.
We monitor our policies and procedures with respect to our contracts on a regular basis to enhance consistent application under similar terms and conditions, as well as compliance with all applicable government regulations and laws. In addition, costs incurred and allocated to contracts with the U.S. Government are routinely audited by the Defense Contract Audit Agency (DCAA).
Environmental
Our manufacturing operations are subject to and affected by federal, state, foreign, and local laws and regulations relating to the protection of the environment. The estimated cost to complete remediation is accrued when it is probable that the company will incur costs to address environmental impacts at sites where the company has been named a Potentially Responsible Party (PRP) and the costs are estimable. To assess the potential impact on the company’s financial statements, management estimates the range of reasonably possible remediation costs that could be incurred by the company, taking into account the facts currently available to the company regarding each site, as well as the current state of technology and prior experience. These estimates are reviewed periodically and adjusted to reflect changes in facts and circumstances. See Risk Factors in Part I, Item 1A, as well as Note 12 to the consolidated financial statements in Part II, Item 8.
In 2009, we established a goal of reducing our greenhouse gas emissions over a five-year period through December 31, 2014. In 2010, we established goals for water usage and solid waste generation. For information on the progress towards achieving our goals, refer to our Corporate Responsibility Report on our Web site. The information contained in our Corporate Responsibility Report should not be deemed to be incorporated by reference into this report.
We have incurred and expect to continue to incur capital and operating costs to comply with applicable environmental laws and regulations and satisfy green initiatives, including our goals. At this time, these costs have not had, and we do not expect that these costs will have, a material adverse effect on our consolidated financial position, results of operations or cash flows.

Item 1A. Risk Factors
Our consolidated financial position, results of operations and cash flows are subject to various risks, many of which are not exclusively within our control, that may cause actual performance to differ materially from historical or projected future performance. We urge you to carefully consider the risk factors described below in evaluating the information contained in this report.
We depend heavily on a single customer, the U.S. Government, for a substantial portion of our business. Changes in this customer’s priorities and spending could have a material adverse effect on our financial position, results of operations, or cash flows.
Our primary customer is the U.S. Government, from which we derived more than 90 percent of our total revenues during each of the past several years. The U.S. Government is implementing significant reductions in government spending and other significant program changes. We cannot predict the impact on existing, follow-on, replacement or future programs from potential changes in priorities due to changes in defense spending levels, military strategy and planning, and/or changes in social-political priorities. A shift in government priorities to programs in which we do not participate and/or reductions in funding for or the termination of programs in which we do participate, unless offset by other programs and opportunities, could have a material adverse effect on our financial position, results of operations and cash flows.
The U.S. Government generally has the ability to terminate contracts, in whole or in part, without prior notice, for its convenience or for default based on performance. In the event of termination for the U.S. Government’s convenience, contractors are generally protected by provisions covering reimbursement for costs incurred on the contracts and profit on those costs but not the anticipated profit that would have been earned had the contract been completed. In some circumstances, however, a U.S. government contract does not have such termination protection. In those cases, we attempt to mitigate the termination risk through other means. To the extent such means are unavailable or do not fully address the costs incurred or profit on those costs, we could face significant losses from the termination for convenience of a contract that lacks termination protection. Termination by the U.S. Government of a contract for convenience also could result in the cancellation of future work on that program. Termination by the U.S. Government of a contract due to our default could require us to pay for re-procurement costs in excess of the original contract price, net of the value of work accepted from the original contract, as well as other damages. Termination of a contract due to our default may expose us to material liability and could have a material adverse effect on our ability to compete for other contracts.
The U.S. Government also has the ability to stop work under a contract for a limited period of time for its convenience. It is possible that the U.S. Government could invoke this ability across a limited or broad number of contracts in this challenging fiscal environment. In the event of a stop work order, contractors are generally protected by provisions covering reimbursement for costs incurred on the contract to date and for costs associated with the temporary stoppage of work on the contract. However, such temporary stoppages and delays could introduce inefficiencies for which we may not be able to negotiate full recovery from the U.S. Government, and could ultimately result in termination for convenience or reduced future orders on certain contracts. In this

challenging environment, our industry could face a significant number of terminations, change orders and stop work orders, which by their volume could further delay and jeopardize our industry's ability to recover costs.
Significant delays or reductions in appropriations for our programs and U.S. Government funding more broadly may negatively impact our business and programs and could have a material adverse effect on our financial position, results of operations or cash flows.
U.S. Government programs are subject to annual congressional budget authorization and appropriation processes. For many programs, Congress appropriates funds on a fiscal year basis even though the program performance period may extend over several years. Consequently, programs are often partially funded initially and additional funds are committed only as Congress makes further appropriations. If we incur costs in excess of funds obligated on a contract, we may be at risk for reimbursement of those costs unless and until additional funds are obligated to the contract. We cannot predict the extent to which total funding and/or funding for individual programs will be included, increased or reduced as part of the annual budget process ultimately approved by Congress or in separate supplemental appropriations or continuing resolutions, as applicable. The impact, severity and duration of the current U.S. economic situation and plans adopted by the U.S. Government, along with pressures on, and uncertainty surrounding, the federal budget and the permissible federal debt limit, could adversely affect the funding for individual programs and delay purchasing or payment decisions by our customers. In the event that government funding for any of our programs becomes unavailable, or is reduced or delayed, our contract or subcontract under such program may be terminated or adjusted by the U.S. Government or the prime contractor, which could have a material adverse effect on our financial position, results of operations and/or cash flows.
In addition, if the existing statutory limit on the amount of permissible federal debt is not raised, we may be required to continue to perform for some period of time on certain of our U.S. Government contracts even if the U.S. Government is unable to make timely payments. An extended delay in the timely payment of billings by the U.S. Government would likely result in a material adverse effect on our financial position, results of operations and cash flows.
In August 2011, Congress enacted the Budget Control Act which, while raising the existing statutory limit on the amount of permissible federal debt, also committed the U.S. Government to significantly reducing the federal deficit over ten years. The Budget Control Act established caps on discretionary spending through 2021, reducing federal spending by approximately $1 trillion over that period relative to the fiscal year (FY) 2012 Presidential budget submission, and called for very substantial automatic spending cuts, known as "sequestration," split between defense and non-defense programs.
In January 2013, Congress enacted the American Taxpayer Relief Act of 2012. It addressed a number of tax code provisions and certain spending issues, but left in place the sequester (although delaying its implementation to March 1, 2013) and did not address other fiscal matters such as the debt ceiling. The delay in the sequester leaves the DoD less time to enact 2013 automatic spending cuts and adds to the uncertainty from such cuts. The nation's debt ceiling is currently expected to be reached during the first half of 2013. Congress and the Administration continue to debate these issues and the terms of a possible national fiscal approach. The outcome of that debate could have a significant impact on future defense spending plans. While the President's proposed FY 2014 Budget is scheduled for release in February 2013, its delivery may be delayed given these unresolved fiscal matters.
We are unable to predict the impact that the delayed automatic cuts or other defense spending cuts would have on funding for our individual programs. Long-term funding for certain programs in which we participate may be reduced, delayed or cancelled. In addition, these cuts could adversely affect the viability of our suppliers and subcontractors. While we believe that our business is well-positioned in areas that the DoD has indicated are areas of focus for future defense spending, the impact of the Budget Control Act and the ongoing fiscal debates remain uncertain and our business and industry could be materially adversely affected.
The President's proposed budget for FY 2013 represented a slight decline from FY 2012 levels. Although Congress passed a continuing resolution to fund U.S. Government operations through March 27, 2013, it is unclear whether annual appropriations bills will be passed during FY 2013. The U.S. Government may operate under a continuing resolution for all of FY 2013, potentially resulting in no new contract or program starts for that year.
The Congressional budget process has been marked by significant debate within the government regarding FY 2013 defense spending. Budget decisions made in this environment will likely have long-term consequences for our company and the entire defense industry. Should sequestration as currently mandated be implemented in March 2013, absent any other changes, we believe it would have serious negative consequences for the security of our country, the defense industrial base, including Northrop Grumman, and the customers, employees, suppliers,

investors, and communities that rely on the companies in the defense industrial base. There are many variables in how the law could be implemented that make it difficult to determine specific impacts; however, we expect that sequestration, as currently provided for under the Budget Control Act, would result in lower revenues, profits and cash flows for our company. Such circumstances may also result in an impairment of our goodwill.
As a U.S. Government contractor, we are subject to various procurement regulations and could be adversely affected by changes in regulations or any negative findings from a U.S. Government audit or investigation.
U.S. Government contractors must comply with many significant procurement regulations and other requirements. These regulations and requirements, although customary in government contracts, increase our performance and compliance costs. New regulations or procurement requirements (including, for example, counterfeit parts and conflict minerals) or changes to current ones, could increase our costs and risks and reduce our margins. Failure to comply with these regulations could, among other things, result in the withholding of payments and adversely impact our reputation and ability to participate in future U.S. Government contracts.
We operate in a highly regulated environment and are routinely audited and reviewed by the U.S. Government and its agencies, such as the Defense Contract Audit Agency (DCAA), Defense Contract Management Agency (DCMA) and DoD Inspector General. These agencies review performance under our contracts, our cost structure and our compliance with applicable laws, regulations and standards, as well as the adequacy of, and our compliance with, our internal control systems and policies. Costs ultimately found to be unallowable or improperly allocated to a specific contract will not be reimbursed or must be refunded if already reimbursed. If an audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties, sanctions or suspension or debarment from doing business with the U.S. Government. Whether or not illegal activities are alleged, the U.S. Government also has the ability to decrease or withhold certain payments when it deems systems subject to its review to be inadequate. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us. If such actions were to result in suspension or debarment, this could have a material adverse effect on our business.
We are from time to time subject to U.S. Government investigations relating to our operations, and we are subject to or expected to perform in compliance with a vast array of federal laws, including but not limited to the Truth in Negotiations Act, the False Claims Act, the Procurement Integrity Act, Cost Accounting Standards (CAS), Federal Acquisition Regulation (FAR), the International Traffic in Arms Regulations promulgated under the Arms Export Control Act, the Close the Contractor Fraud Loophole Act and the Foreign Corrupt Practices Act. If we are found to have violated the law, or are found not to have acted responsibly as defined by the law, we may be subject to reductions of the value of contracts, contract modifications or termination and the assessment of penalties, fines, or compensatory or treble damages, which could have a material adverse effect on our financial position, results of operations, or cash flows. Such matters could also result in suspension or debarment. Given our dependence on government contracting and authorizations, suspension or debarment could have a material adverse effect on our financial position, results of operations or cash flows.
Changes to business practices for U.S. Government contractors could have a significant adverse effect on current programs, potential new awards and the processes by which procurements are awarded and managed.
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, and a reprioritization of available defense funds to key areas for future defense spending. For example, the DoD’s Better Buying Power Initiative continues to evolve in its efforts to reduce costs, gain efficiencies, refocus priorities and enhance business practices used by the DoD, including those used to procure goods, services and solutions from defense contractors. In addition, the DCMA has implemented cost recovery initiatives designed to prioritize efforts to recover costs and close open audits. As a result of certain of these initiatives, we have experienced and may continue to experience an increased number of audits and/or a lengthened period of time required to close open audits. More recently, the thresholds for certain allowable costs are being challenged and refined.
These efforts have had, and we expect them to continue to have, a significant impact on the contracting environment in which we do business. In support of the implementation of the Better Buying Power Initiative, the U.S. Government is issuing new regulations and requirements that are shifting additional responsibility and performance risks to the contractor. While the impact to our business as a result of these changes remains uncertain, our business and industry could be materially adversely affected.

Competition within our markets and an increase in bid protests may reduce our revenues and market share.
We operate in highly competitive markets and our competitors may have more extensive or more specialized engineering, manufacturing and marketing capabilities or be willing to accept more risk or lower margins in competing for contracts. We have seen, and anticipate that we will continue to see, increased competition in some of our core markets, especially as a result of the reduction in budgets for many U.S. Government agencies and fewer new program starts. Changes in U.S. defense spending may limit certain future market opportunities. We are facing increasing competition in our domestic and international markets from U.S., foreign and multinational firms. Additionally, some customers, including the DoD, may turn to commercial contractors, rather than traditional defense contractors, for information technology and other support work, or may utilize small business contractors or determine to source work internally rather than hiring a contractor. If we are unable to continue to compete successfully against our current or future competitors, we will experience declines in revenues and market share, which would negatively impact our financial position, results of operations, or cash flows.
We also are seeing an increasing number of bid protests from unsuccessful bidders on new program awards. Bid protests could result in significant expense to the company, contract modifications or the award decision being overturned and loss of the contract award. Even where a bid protest does not result in the loss of an award, the resolution can extend the time until the contract activity can begin, and delay earnings.
Our future success depends, in part, on our ability to develop new products and new technologies and maintain technologies, facilities, equipment and a qualified workforce to meet the needs of current and future customers.
Many of the markets in which we operate are characterized by rapidly changing technologies. The product, program and service needs of our customers change and evolve regularly. Our success in the competitive defense industry depends upon our ability to develop and market our products and services, as well as our ability to provide the people, technologies, facilities, equipment and financial capacity needed to deliver those products and services with maximum efficiency. If we fail to maintain our competitive position, we could lose a significant amount of future business to our competitors, which would have a material adverse effect on our ability to generate favorable financial results and maintain market share.
Our operating results are heavily dependent upon our ability to attract and retain sufficient personnel with requisite skills and/or security clearances. If qualified personnel become scarce, we could experience higher labor, recruiting or training costs in order to attract and retain such employees. Failure to maintain a qualified workforce would result in difficulty in performing under our contracts.
Approximately 3,300 of our 68,100 employees are covered by an aggregate of 17 collective bargaining agreements, and we expect to negotiate or re-negotiate renewals for three of our collective bargaining agreements in 2013. Collective bargaining agreements generally expire after three to five years, and are subject to renegotiation upon expiration. We may experience difficulties with renewals and renegotiations of existing collective bargaining agreements. If we experience such difficulties, we could incur additional expenses and may be subject to work stoppages. Any such expenses or delays could adversely affect programs served by employees who are covered by collective bargaining agreements.
Many of our contracts contain performance obligations that require innovative design capabilities, are technologically complex, require state-of-the-art manufacturing expertise or are dependent upon factors not wholly within our control. Failure to meet these obligations could adversely affect our profitability and future prospects.
We design, develop and manufacture technologically advanced and innovative products and services, which are 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, inability to achieve learning curve assumptions, manufacturing materials or components could prevent us from achieving contractual requirements.
In addition, our products cannot be tested and proven in all situations and are otherwise subject to unforeseen problems. Examples of unforeseen problems that could negatively affect revenue and profitability include loss on launch of spacecraft, premature failure of products that cannot be accessed for repair or replacement, problems with quality and workmanship, country of origin, delivery of subcontractor components or services and degradation of product performance. These failures could result, either directly or indirectly, in loss of life or property. 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.

Certain contracts, primarily involving space satellite systems, contain provisions that entitle the customer to recover fees in the event of partial or complete failure of the system upon launch or subsequent deployment for less than a specified period of time. Under such terms, we could be required to forfeit fees previously recognized and/or collected. We have not experienced any material losses in the last decade in connection with such contract performance incentive provisions. However, if we were to experience launch failures or complete satellite system failures in the future, for example, such events could have a material adverse effect on our financial position, results of operations, or cash flows.
Contract cost growth on fixed-price and other contracts that do not result in increased contract value exposes us to reduced profitability and the potential loss of future business.
Our operating income is adversely affected when we incur certain contract costs or certain increases in contract costs that cannot be billed to customers. This cost growth can occur if estimates to complete increase or initial estimates used for calculating the contract cost were incorrect. The cost estimation process requires significant judgment and expertise. Reasons for cost growth may include unavailability or reduced productivity of labor, the nature and complexity of the work to be performed, technical or quality issues, the timeliness and availability of materials, major subcontractor performance and quality of their products, the effect of any delays in performance, availability and timing of funding from the customer, and natural disasters. Further, items affecting our contract value may include the inability to recover any claims included in the estimates to complete. A significant change in estimates on one or more programs could have a material adverse effect on our consolidated financial position, results of operations, or cash flows.
Our risk varies with the type of contract. Due to their nature, firm fixed-price contracts inherently have more risk than cost type contracts. In 2012, approximately 44 percent of our annual revenues were derived from fixed-price contracts. We typically enter into fixed-price contracts where costs can be reasonably estimated based on experience. In addition, our contracts contain provisions relating to cost controls and audit rights. Should the terms specified in our contracts not be met, then profitability may be reduced or a loss may be incurred. Fixed-price development work comprises a small portion of our fixed-price contracts and inherently has more uncertainty as to future events than production contracts and therefore more variability in estimates of the costs to complete the development stage. As work progresses through the development stage into production, the risks associated with estimating the total costs of the contract are generally reduced. While management uses its best judgment to estimate costs associated with fixed-price development contracts, future events could result in either upward or downward adjustments to those estimates.
Other contracts are also subject to risk, for example, under a fixed price incentive contract, the allowable costs incurred by the contractor are paid up to a ceiling, which can affect profitability. Further, under a cost type contract, the allowable costs incurred by the contractor are also subject to reimbursement plus a fee. We often enter into cost type contracts for development programs with complex design and technical challenges. These cost type programs typically have award or incentive fees that are subject to uncertainty and may be earned over extended periods. In these cases, the associated financial risks are primarily in lower profit rates or program cancellation if cost, schedule, or technical performance issues arise.
We use estimates when accounting for contracts. Changes in estimates could affect our profitability and our overall financial position.
When agreeing to contractual terms, we make assumptions and projections about future conditions and events, many of which extend over long periods. These assumptions and projections assess the cost, productivity and availability of labor, future levels of business base, complexity of the work to be performed, cost and availability of materials, impact of potential delays in performance and timing of product deliveries. Contract accounting requires judgment relative to assessing risks, estimating contract revenues and costs, and making assumptions for schedule and technical issues. Due to the size and nature of many of our contracts, the estimation of total revenues and costs at completion is complicated and subject to many variables. Incentives, awards or penalties related to performance on contracts are considered in estimating revenue and profit rates, and are recorded when there is sufficient information to assess anticipated performance. Suppliers’ assertions are also assessed and considered in estimating costs and profit rates.
Because of the significance of the judgment and estimation processes described above, it is possible that materially different amounts could be obtained if different assumptions were used or if the underlying circumstances were to change. Changes in underlying assumptions, circumstances or estimates may have a material adverse effect upon the profitability of one or more of the affected contracts and our performance. See Critical Accounting Policies, Estimates, and Judgments in Part II, Item 7.

Our earnings and margins depend, in part, on subcontractor performance as well as raw material and component availability and pricing.
We rely on other companies to provide raw materials and major components for our products and rely on subcontractors to produce hardware elements and sub-assemblies and perform some of the services that we provide to our customers. Disruptions or performance problems caused by our subcontractors and vendors could have an adverse effect on our ability to meet our commitments to customers. Our ability to perform our obligations on time as a prime contractor could be adversely affected if one or more of the vendors or subcontractors are unable to provide the agreed-upon products or materials or perform the agreed-upon services in a timely and cost-effective manner.
Our costs may increase over the term of our contracts. Through cost escalation provisions contained in some of our U.S. Government contracts, we may be protected from increases in costs to the extent that the increases in our costs are in line with industry indices. However, the difference in basis between our actual costs and these indices may expose us to cost uncertainty even with these provisions. A significant delay in supply deliveries of our key raw materials or components required in our production processes could have a material adverse effect on our financial position, results of operations, or cash flows.
In connection with our government contracts, we are required to procure certain materials, components and parts from supply sources approved by the U.S. Government. There are currently several components for which there may only be one supplier. If a sole source supplier cannot meet our needs, we may be unable to find a suitable alternative. Consistent with the industry’s efforts, our procurement practices are intended to reduce the likelihood of our procurement of counterfeit parts or materials. If we are unable to procure needed materials, components or parts, or if the parts we procure are counterfeit, our financial position, results of operations, or cash flows could be materially adversely affected.
Changes in economic conditions, as well as changes in the defense budget, can adversely affect the ability of our subcontractors and suppliers to perform and further increase this risk.
Changes in future business conditions could cause business investments and/or recorded goodwill and other long-lived assets to become impaired, resulting in substantial losses and write-downs that would reduce our operating income.
Goodwill accounts for approximately half of our recorded total assets. We test goodwill amounts for impairment at least annually and consider whether an interim test is required if we believe potential impairment exists. The annual impairment test is based on several factors requiring judgment. We face continued uncertainty in our business environment due to the substantial fiscal and economic challenges facing the U.S. Government, our primary customer, including the potential for sequestration and issues surrounding the national debt ceiling. Potential contract cancellations, modifications or terminations may arise from resolution of these issues and could cause our revenues, profits and cash flows to be substantially lower than our current projections. In addition, market-based inputs to the calculations in the impairment test, such as weighted average cost of capital and terminal value (based on market comparisons) could also be negatively impacted. Such circumstances may result in an impairment of our goodwill. Further, the carrying values of our reporting units are significantly influenced by a number of factors including the discount rate used to determine our net pension liability. Therefore an increase in the discount rate on our pension liability in 2013 or beyond could result in an impairment of goodwill absent any changes discussed above. We continue to monitor the recoverability of the carrying value of our goodwill and other long-lived assets.
As part of our overall strategy, we may, from time to time, acquire an interest in a business. Even after careful integration efforts, actual operating results may vary significantly from initial estimates and we may experience unforeseen issues that adversely affect the value of our goodwill or other long-lived assets.

Our international business exposes us to additional risks.
Our international business remains subject to numerous political and economic factors, regulatory requirements and other risks associated with doing business in foreign countries. Our international business is subject to U.S. and foreign laws and regulations, including, without limitation, regulations relating to import-export control, technology transfer restrictions, repatriation of earnings, exchange controls, the Foreign Corrupt Practices Act and certain other anti-corruption laws, and the anti-boycott provisions of the U.S. Export Administration Act. Failure by us, our employees, or others working on our behalf to comply with these laws and regulations could result in administrative, civil, or criminal liabilities, including suspension or debarment from government contracts or suspension of our export privileges, which could have a material adverse effect on us. Changes in regulations, political environments or security risks may affect our ability to conduct business in foreign markets, including those regarding investment, procurement and repatriation of earnings. Our international business may also be impacted by changes in foreign national priorities and government budgets and may be further impacted by global economic conditions and fluctuations in foreign currency exchange rates. In addition, our international contracts may include industrial cooperation agreements requiring specific in-country purchases, investments, manufacturing agreements or other financial obligations, known as offset obligations, and provide for penalties if we fail to meet such requirements.
The services and products we provide internationally, including those provided by subcontractors, are sometimes in countries with unstable governments, in areas of military conflict or at military installations. This increases the risk of an incident resulting in harm or loss of life to our employees, subcontractors or other third parties or damage to our products. We maintain insurance and take other steps to mitigate the risk and potential liabilities related to our international operations, but these steps may not be adequate to prevent loss or to cover resulting claims and liabilities, and we may be forced to bear substantial costs (see additional discussion of possible inadequacy of our insurance coverage below). In addition, any accidents or incidents that occur in connection with our international operations could result in negative publicity for the company, which may adversely affect our reputation and make it more difficult for us to compete for future contracts or attract and retain employees or result in the loss of existing and future contracts. The impact of these factors is difficult to predict, but one or more of them could adversely affect our financial position, results of operations, or cash flows.
Our reputation and our ability to do business may be impacted by the improper conduct of employees, agents or business partners.
We have implemented extensive policies, procedures, training and other compliance controls to prevent misconduct by employees, agents or others with whom we are doing business that would violate the applicable laws of the jurisdictions in which we operate, including laws governing improper payments to government officials, the protection of export controlled or classified information, cost accounting and billing, competition and data privacy. However, we cannot ensure that we will prevent all such misconduct committed by our employees, agents or others with whom we are doing business, and the risk of improper conduct may increase in the current environment. Such improper actions could subject us to administrative, civil or criminal investigations and monetary and non-monetary penalties, including suspension and debarment, which could negatively impact our reputation and ability to conduct business and could have a material adverse effect on our financial position, results of operations, or cash flows.

Our business could be negatively impacted by security threats, including physical and cybersecurity threats, and other disruptions.
As a defense contractor, we face various security threats, including cybersecurity threats to gain unauthorized access to sensitive information; threats to the safety of our directors, officers, and employees; threats to the security of our facilities and infrastructure; and threats from terrorist acts. Although we utilize various procedures and controls to monitor and mitigate these threats, there can be no assurance that these procedures and controls will be sufficient to prevent security threats from materializing. If any of these events were to materialize, they could lead to losses of sensitive information or capabilities, harm to personnel or infrastructure, or damage to our reputation, and could have a material adverse effect on our financial position, results of operations, or cash flows.
Cybersecurity threats are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data, denial of service attacks, and other electronic security breaches that could lead to disruptions in mission critical systems, unauthorized release of confidential or otherwise protected information and corruption of data. These events could damage our reputation and lead to financial losses from remedial actions, loss of business or potential liability.
We also manage information technology systems for various customers and other third parties. While we operate under information security policies and procedures for managing these systems, we generally face similar cybersecurity threats for these systems as for our own.
Unforeseen environmental costs could have a material adverse effect on our financial position, results of operations, or cash flows.
Our operations are subject to and affected by a variety of federal, state, local and foreign environmental laws and regulations. In addition, we could be affected by future laws or regulations, including those imposed in response to climate change concerns and other actions. Compliance with current and future environmental laws and regulations currently requires and is expected to continue to require significant operating and capital costs.
Environmental laws and regulations provide for substantial fines and criminal sanctions for violations, and may limit our operations or require the installation of costly pollution control equipment or operational changes to limit pollution emissions or discharges and/or decrease the likelihood of accidental hazardous substance releases. We also incur, and expect to continue to incur, costs to comply with current federal and state environmental laws and regulations related to the cleanup of pollutants previously released into the environment. In addition, if we were found to be in violation of the Federal Clean Air Act or the Clean Water Act, the facility or facilities involved in the violation could be placed by the EPA on the “Excluded Parties List” maintained by the General Services Administration. The listing could continue until the EPA concludes that the cause of the violation had been corrected. If we were listed on the Excluded Parties List it could have a material adverse effect on our financial position, results of operations and cash flows. Listed facilities generally cannot be used in performing any U.S. Government contract until the violation is corrected.
The adoption of new laws and regulations, stricter enforcement of existing laws and regulations, imposition of new cleanup requirements, discovery of previously unknown or more extensive contamination, litigation involving environmental impacts, sanctions or penalties, could negatively impact our ability to recover such costs under previously priced contracts or financial insolvency of other responsible parties could cause us to incur costs in the future that could have a material adverse effect on our financial position, results of operations, or cash flows.

We are subject to various claims and litigation that could ultimately be resolved against us.
The size, nature and complexity of our business make us highly susceptible to claims and litigation. We are and may become subject to various environmental claims, income tax matters, compliance matters, claims, investigations, and administrative, civil or criminal litigation, which could divert financial and management resources and result in fines, penalties, compensatory or treble damages or non-monetary relief. Government regulations also provide that certain allegations against a contractor may lead to suspension or debarment from government contracts or suspension of export privileges for the company or one or more of its components. Suspension or debarment could have a material adverse effect on the company because of the company's reliance on government contracts and authorizations. Investigations, claims or litigation, if ultimately resolved against us, could have a material adverse effect on our financial position, results of operations or cash flows. Any investigation, claim, or litigation, even if fully indemnified or insured, could negatively impact our reputation among our customers and the public, and make it more difficult for us to compete effectively or obtain adequate insurance in the future.
We may be unable adequately to protect our intellectual property rights, which could affect our ability to compete.
We own many U.S. and foreign patents, trademarks, copyrights, and other forms of intellectual property, and we license certain intellectual property rights to and from third parties. The U.S. Government generally holds licenses to certain intellectual property that we develop in performance of government contracts, and it may use or authorize others to use certain such intellectual property. The U.S. Government appears to be asserting or seeking to assert more extensive intellectual property rights. Our intellectual property is also subject to challenge, invalidation, misappropriation or circumvention by third parties.
We also rely significantly upon proprietary technology, information, processes and know-how that are not protected by patents. We seek to protect this information through trade secret or confidentiality agreements with our employees, consultants, subcontractors and other parties, as well as through other measures. These agreements and other measures may not provide adequate protection for our unpatented proprietary information. In the event of an infringement of our intellectual property rights, a breach of a confidentiality agreement or divulgence of proprietary information, we may not have adequate legal remedies to maintain our intellectual property. Litigation to determine the scope of intellectual property rights, even if ultimately successful, could be costly and could divert management’s attention away from other aspects of our business. In addition, our trade secrets may otherwise become known or be independently developed by competitors. In some instances, we have licensed the proprietary intellectual property of others, but we may be unable in the future to secure the necessary licenses to use such intellectual property on commercially reasonable terms. If we are unable adequately to protect our intellectual property rights, against claims by the U.S. Government or others our business could be adversely affected.
Our business is subject to disruption caused by natural disasters, environmental disasters and other factors that could adversely affect our profitability and our overall financial position.
We have significant operations located in regions of the U.S. that may be exposed to earthquakes, damaging storms, and other natural disasters, including environmental disasters. Although preventative measures may help to mitigate damage, the damage and disruption resulting from natural and environmental disasters may be significant. If insurance or other risk transfer mechanisms are unavailable or insufficient to recover all costs, our financial position, results of operations, or cash flows could be materially adversely affected.
Our suppliers and subcontractors are also subject to natural disasters that could affect their ability to deliver or perform under a contract. Performance failures by our subcontractors due to natural and environmental disasters may adversely affect our ability to perform our obligations on the prime contract. This could reduce our profitability due to damages or other costs that may not be fully recoverable from the subcontractor or from the customer, could result in a termination of the prime contract and could have an adverse effect on our ability to compete for future contracts.
Natural disasters could also disrupt our workforce, electrical and other power distribution networks, including computer and internet operation and accessibility, and the critical industrial infrastructure needed for normal business operations. These disruptions could cause adverse effects on our profitability and performance.

Our insurance coverage, customer indemnifications or other liability protections may be inadequate to cover all of our significant risks or our insurers may deny coverage of or be unable to pay for material losses we incur, which could adversely affect our profitability and overall financial position.
We endeavor to obtain insurance agreements from established markets to cover significant risks and liabilities (including, for example, natural disasters and product liability). Not every risk or liability can be insured, and, for risks that are insurable, the policy limits and terms of coverage reasonably obtainable in the market may not be sufficient to cover all actual losses or liabilities incurred. Even if insurance coverage is available, we may not be able to obtain it at a price or on terms acceptable to us.
Disputes with insurance carriers over policy terms or the insolvency of one or more of our insurers may significantly affect the amount or timing of cash flows and, if litigation over coverage terms with the insurer becomes necessary, an outcome unfavorable to us may have a material adverse effect on our financial position, results of operations, or cash flows.
In some circumstances we may be entitled to certain legal protections or indemnifications from our customers through contractual provisions, laws, regulations or otherwise. However, these protections are typically subject to certain terms or limitations and may not be sufficient to cover all losses or liabilities incurred.
Anticipated benefits of mergers, acquisitions, joint ventures, spin-offs or strategic alliances may not be realized.
As part of our overall strategy, we may, from time to time, merge with or acquire businesses, dispose of or spin-off businesses, form joint ventures or create strategic alliances. Whether we realize the anticipated benefits from these transactions depends, in part, upon the integration between the businesses involved, the performance of the underlying products, capabilities or technologies, the management of the operations and market conditions following these transactions. Accordingly, our financial results could be adversely affected from unanticipated performance issues, transaction-related charges, liabilities, amortization of expenses related to intangibles, charges for impairment of long-term assets, guarantees, partner performance and indemnifications. Divestitures may result in continued financial involvement in the divested business, such as through guarantees, indemnifications, or other financial arrangements, following the transaction. Although we have established procedures and processes to mitigate these risks, there is no assurance that these transactions will be successful.
Market volatility and adverse capital and credit market conditions may affect our suppliers' ability to access cost-effective sources of funding and expose us to risks associated with the financial viability of suppliers.
A tightening of credit could adversely affect our suppliers’ ability to obtain financing. Delays in suppliers’ ability to obtain financing, or the unavailability of financing, could cause us to be unable to meet our contract obligations and could adversely affect our financial position, results of operations, or cash flows. The inability of our suppliers to obtain financing could also result in the need for us to transition to alternate suppliers, which could result in significant incremental cost and delay or the need for us to provide other supplemental means to support our existing suppliers.
Pension and medical expenses associated with our retirement benefit plans may fluctuate significantly depending upon changes in actuarial assumptions, future investment performance of plan assets, future trends in health care costs and legislative or other regulatory actions.
A substantial portion of our current and retired employee population is covered by pension and other post-retirement benefit plans, the costs of which are dependent upon our various assumptions, including estimates of rates of return on benefit related assets, discount rates for future payment obligations, rates of future cost growth and trends for future costs. In addition, funding requirements for benefit obligations of our pension and post-retirement benefit plans are subject to legislative and other government regulatory actions. Variances from these estimates could have a material adverse effect on our financial position, results of operations, or cash flows.
Additionally, due to government regulations, pension plan cost recoveries under our government contracts occur in different periods from when those pension costs are recognized for financial statement purposes or when pension funding is made. These timing differences could have a material adverse effect on our cash flow from operations. In December 2011, the cost accounting rules were revised in order to partially harmonize the measurement and period of assignment of defined benefit pension plan costs allocable to U.S. Government contracts and the minimum required contribution under the Employee Retirement Income Security Act of 1974 (ERISA), as amended by the Pension Protection Act (PPA) of 2006. We anticipate that this rule will better align, but not eliminate, mismatches between ERISA funding requirements and CAS pension costs for U.S. Government CAS covered contracts.

Unanticipated changes in our tax provisions or exposure to additional income tax liabilities could affect our profitability and cash flow.
We are subject to income taxes in the U.S. and many foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of business, there are many transactions and calculations where the ultimate tax determination is uncertain. Furthermore, changes in applicable domestic or foreign income tax laws and regulations, or their interpretation, could result in higher or lower income tax rates assessed or changes in the taxability of certain sales or the deductibility of certain expenses, thereby affecting our income tax expense and profitability. Deferred tax assets are required to be measured at the statutory tax rate currently in effect, therefore a change in the U.S. corporate tax rate would result in a remeasurement of our net deferred tax asset through the income tax provision. The final determination of any tax audits or related litigation could be materially different from our historical income tax provisions and accruals. Additionally, changes in our tax rate as a result of a change in the mix of earnings in countries with differing statutory tax rates, changes in our overall profitability, changes in tax legislation, changes in the valuation of deferred tax assets and liabilities, changes in differences between financial reporting income and taxable income, the results of audits and the examination of previously filed tax returns by taxing authorities and continuing assessments of our tax exposures could impact our tax liabilities and significantly affect our income tax expense, profitability and cash flow.
Our nuclear-related operations subject us to various environmental, regulatory, financial and other risks.
Our nuclear-related operations subject us to various risks, including potential liabilities relating to harmful effects on the environment and human health that may result from nuclear-related operations and the storage, handling and disposal of radioactive materials. We are also subject to reputational harm and potential liabilities arising out of a nuclear incident, whether or not it is within our control. The U.S. Government and prime contractors provide certain indemnity protection under certain of our contracts pursuant to, or in connection with, Public Law 85-804 and the Price-Anderson Nuclear Industries Indemnity Act for certain nuclear-related risks. If there was a nuclear incident and that indemnity protection was not available to cover our losses and liabilities, it could have a material adverse effect on our financial position, results of operations, or cash flows.
If all or any portion of the spin-off of our former Shipbuilding business or certain internal transactions undertaken in anticipation of the spin-off transaction are determined to be taxable for U.S. federal income tax purposes, we and our shareholders that are subject to U.S. federal income tax may incur significant U.S. federal income tax liabilities.
In connection with the spin-off of our former Shipbuilding business, we received a letter ruling from the IRS and an opinion of counsel confirming that we and our shareholders would not recognize any taxable income, gain or loss for U.S. federal income tax purposes as a result of the merger, the internal reorganization or the distribution, except that our shareholders who receive cash in lieu of fractional shares would recognize gain or loss with respect to such cash. The ruling and the opinion relied on certain facts, assumptions, representations and undertakings from us and HII regarding the past and future conduct of the companies’ respective businesses and other matters.
We are not aware of any facts or circumstances that would cause any of the factual statements or representations in the IRS ruling or the opinion to be incomplete or untrue at the time of the spin-off transaction. Nevertheless, if the IRS determines that any of the factual statements or representations that the IRS ruling or the opinion was based on were incomplete or untrue, or if certain facts or circumstances upon which the IRS ruling or the opinion was based were materially different from those at the time of the spin-off, we and our shareholders may not be able to rely on the IRS ruling or the opinion of counsel and could be subject to significant tax liabilities.
Even if the spin-off transaction otherwise qualifies as tax-free for U.S. federal income tax purposes, the internal reorganization and distribution may be taxable to us (but not to our shareholders) if certain events occur, including, if before March 31, 2013 there are one or more acquisitions (including issuances) of the stock of either us or HII, representing 50% or more of the then-outstanding stock of either corporation and the acquisition or acquisitions are deemed to be part of a plan or series of related transactions that include the distribution; we cease to engage appropriately in the conduct of a substantial part of our existing business; or, we or HII repurchase shares in excess of specified levels before March 31, 2013. If such tax were incurred, the tax liability would be substantial. HII has agreed not to undertake transactions that would reasonably be expected to trigger such tax, and we intend to avoid any such transactions.

The spin-off of our former Shipbuilding business may expose us to potential claims and liabilities.
In connection with the spin-off transaction, we entered into a number of agreements with HII setting forth certain rights and obligations of the parties after the separation. For example, under the Separation and Distribution Agreement, from and after the spin-off transaction, each of HII and Northrop Grumman is generally responsible for the debts, liabilities and other obligations related to the business or businesses that it owns and operates following the consummation of the spin-off. It is possible that a court would disregard the allocation agreed to between us and HII, and require that we assume responsibility for certain obligations allocated to HII (for example, tax and/or environmental liabilities), particularly if HII were to refuse or were unable to pay or perform such obligations.
In addition, third parties could seek to hold us responsible for any of the liabilities or obligations for which HII has agreed to be responsible and/or to indemnify us, directly or indirectly. The indemnity related rights we have under our agreements with HII may not be sufficient to protect us against such liabilities. Even if we ultimately succeed in recovering from HII or the U.S. Government any amounts for which we are held liable, we may be required to record these losses ourselves until such time as the indemnity contribution is paid. In addition, certain indemnities that we may be required to provide HII are not subject to a cap, may be significant, and could negatively impact our business. These risks could negatively affect our business and could have a material adverse effect on our financial position, results of operations, or cash flows.

Item 3. Legal Proceedings
We have provided information about certain legal proceedings in which we are involved in Note 11 to the consolidated financial statements in Part II, Item 8.
We are a party to various investigations, lawsuits, claims and other legal proceedings, including government investigations and claims, that arise in the ordinary course of our business. These types of matters could result in fines, penalties, compensatory or treble damages or non-monetary relief. U.S. Government regulations also provide that certain allegations against a contractor may lead to suspension or debarment from future U.S. Government contracts or suspension of export privileges for the company or one or more of its components. Suspension or debarment could have a material adverse effect on the company because of the company's reliance on government contracts and authorizations. The nature of legal proceedings is such that we cannot assure the outcome of any particular matter. However, based on information available to us to date and other than as noted in Note 11 to the consolidated financial statements, we do not believe that the outcome of any matter pending against the Company is likely to have a material adverse effect on the company's consolidated financial position as of December 31, 2012 or its annual results of operations or cash flows. For further information on the risks we face from existing and future investigations, lawsuits, claims and other legal proceedings, please see Risk Factors in Part I, Item 1A, of this report.

In June 2010, our board of directors authorized a share repurchase program of up to $2.0 billion of the company’s common stock. Following this initial authorization, our board of directors increased the remaining repurchase authorization to $4.0 billion in April 2011. After further repurchases reduced the remaining authorization to less than $1 billion, the board of directors again increased the remaining authorization to $2.0 billion in September 2012. As of December 31, 2012, repurchases under the program totaled $3.9 billion and $1.5 billion remained under this share repurchase authorization. The repurchase program will expire when we have used all authorized funds for repurchase.
(2)
Includes commissions paid.
Share repurchases take place under pre-established programs, depending on market conditions, in the open market, or in privately negotiated transactions. The company retires its common stock upon repurchase and has not made any purchases of common stock other than in connection with these publicly announced repurchase program authorizations.
In connection with the spin-off of the former shipbuilding business (see Note 3 in Part II, Item 8), we obtained a Private Letter Ruling from the Internal Revenue Service that generally limits our share repurchases to approximately 88 million shares within two years of the spin-off. The limitation expires on March 31, 2013. Since the spin-off we have repurchased approximately 61 million shares of our common stock, and as of December 31, 2012, the company may repurchase approximately 27 million shares under the Private Letter Ruling limitation. Cash available from unusual transactions, such as the disposition of significant assets, should they arise, can be used to repurchase additional shares.
(f) Securities Authorized for Issuance Under Equity Compensation Plans.
For a description of securities authorized under our equity compensation plans, see Note 14 to our consolidated financial statements in Part II, Item 8.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
OVERVIEW
Political and Economic Environment
The U.S. Government continues to face substantial fiscal and economic challenges that affect funding for its non-discretionary and discretionary budgets. Part I of the Budget Control Act of 2011 (Budget Control Act) provided for a reduction in defense budgets by at least $487 billion over a ten year period. Part II provided the potential for substantial additional reductions, through a process known as “sequestration.” The President's proposed fiscal year (FY) 2013 budget represented a slight decline for defense from FY 2012. While Congress has not passed a FY 2013 budget, it did pass a six-month continuing resolution that funds the U.S. Government through March 27, 2013. This continuing resolution restricts new starts and provides for discretionary spending levels that represent a slight increase over the FY 2012 budget. It is unclear whether annual appropriations bills will be passed during FY 2013. The U.S. Government may operate under a continuing resolution for all of FY 2013, restricting new contract or program starts for that year.
The American Taxpayer Relief Act of 2012 was enacted in January 2013. It addressed a number of tax code provisions and certain spending issues but left in place the sequester (although delaying its implementation to March 1, 2013) and did not address other fiscal matters such as the debt ceiling. The nation's debt ceiling is currently expected to be reached during the first half of 2013. Congress and the Administration continue to debate these issues and the terms of a possible national fiscal approach. The outcome of that debate could have a significant impact on future defense spending plans. While the President's proposed FY 2014 budget is scheduled for release in February 2013, its delivery may be delayed given these unresolved broad fiscal matters.
The Congressional budget process to finalize FY 2013 defense spending also has been marked by continued uncertainty and significant debate, increasing the possibility of sequestration occurring. As noted above, the Budget Control Act calls for additional substantial defense spending reductions through sequestration, if Congress is unable to agree on a budget that conforms with the Budget Control Act requirements. Should sequestration, as currently mandated, be implemented in March 2013, absent any other changes, we expect it would have serious negative consequences for the security of our country, the defense industrial base, including Northrop Grumman, and the customers, employees, suppliers, investors, and communities that rely on the companies in the defense industrial base.
There continues to be much uncertainty also regarding how sequestration would be implemented, if it were to go into effect. There are many variables in how the law could be applied that make it difficult to determine the specific impacts. However, we expect that sequestration, as currently provided for under the Budget Control Act, would result in lower revenues, profits and cash flows for our company.
Members of Congress are discussing various options to address sequestration's automatic spending cuts. While we cannot predict the outcome of these efforts, it is likely that budget decisions made in this environment will have long-term consequences for our company and the entire defense industry.
In addition to fiscal and budgetary constraints, we expect defense spending to be affected by the drawdown of U.S. force levels tied to current major overseas deployments and other shifts in defense missions and priorities. As overall defense spending declines, the Department of Defense (DoD) is continuing to re-evaluate the role and structure of the U.S. military. In 2012, the DoD announced a new defense strategy intended to guide its priorities and budgeting decisions. The guidance calls for the U.S. military to project power globally and operate effectively in all domains, including cybersecurity, and it places particular emphasis on Asia Pacific as an area of strategic focus.
We believe that spending on recapitalization, modernization and maintenance of defense, intelligence, and homeland security assets will continue to be a national priority. Future defense spending is expected to include the development and procurement of new manned and unmanned military platforms and systems along with advanced electronics and software to enhance the capabilities of existing individual systems and provide real-time integration of individual surveillance, information management, strike, and battle management platforms. We expect significant new competitive opportunities to include long range strike, missile defense, command and control, network communications, enhanced situational awareness, satellite systems, restricted programs, cybersecurity, technical services and information technology contracts, as well as numerous international and homeland security programs.

Operating Performance Assessment and Reporting
We manage and assess the performance of our business based on our performance on contracts and programs (two or more closely-related contracts), with consideration given to the Critical Accounting Policies, Estimates and Judgments described later in this section. Revenue on our portfolio of long-term contracts is generally recognized using the percentage of completion method, primarily the cost-to-cost method, but in some cases the units-of-delivery method of percentage of completion accounting. As a result, sales tend to fluctuate in concert with costs across our large portfolio of contracts. Due to Federal Acquisition Regulations (FAR) rules that govern our business, most types of costs are allowable, and we do not focus on individual cost groupings (such as manufacturing, engineering, and design labor costs, subcontractor costs, material costs, overhead costs, and general and administrative costs), as much as we do on total contract costs, which is the key driver of both sales and operating income.
Our contract management process involves the use of contract estimates-at-completion (EACs) that are generally prepared and evaluated on a bottoms-up basis at least annually and reviewed on a quarterly basis over the contract's period of performance. These EACs include an estimated contract operating margin based initially on the contract award amount, adjusted to reflect estimated risks related to contract performance. These risks typically include technical risk, schedule risk and performance risk based on our evaluation of the contract effort. Similarly, the EACs include identified opportunities for operating margin rate improvement. Over the contract's period of performance, our program management organizations perform evaluations of contract performance and adjust the contract revenue and cost estimates to reflect the latest reliable information available.
Our business and program management organizations are comprised of skilled professional managers whose objective is to satisfy the customer's expectations, deliver high quality products and services, and manage contract risks and opportunities to achieve an appropriate operating margin rate on the contract. Our comprehensive business and contract management process is a coordinated process involving personnel with expertise from various disciplines including production control, contracts, cost management, mission assurance and quality, finance and supply chain, among others. As part of this overall contract management function, these personnel monitor compliance with our critical accounting policies related to contract accounting and compliance with U.S. Government regulations. Contract operating income and period-to-period contract operating margin rates are adjusted over the contract's period of performance to reflect the latest estimated revenue and cost for the contract, including changes in the risks and opportunities affecting the contract. Such adjustments may have a favorable or unfavorable effect on operating income depending upon the specific conditions affecting each contract.
In evaluating our operating performance, we look primarily at changes in sales and operating income, including the effects of meaningful changes in operating income as a result of changes in contract estimates. Where applicable, significant fluctuations in operating performance attributable to individual contracts or programs, or changes in a specific cost element across multiple contracts are described in our analysis. Based on this approach and the nature of our operations, the discussion of results of operations first focuses around our four segments before distinguishing between products and services. Changes in sales are generally described in terms of volume, deliveries or other indicators of sales activity, and contract mix. For purposes of this discussion, volume generally refers to increases or decreases in cost or sales from production/service activity levels or delivery rates. Performance refers to changes in contract margin rates for the period, primarily related to the changes in estimates referred to above.

For financial statement purposes, we account for our employee pension plans in accordance with GAAP under Financial Accounting Standards (FAS). We charge the costs of these plans to our contracts in accordance with the FAR and the related Cost Accounting Standards (CAS) that govern such plans. The net FAS/CAS pension adjustment is pension expense determined in accordance with GAAP less pension expense charged to contracts and included in segment operating income. Unallocated corporate expenses generally include the portion of corporate expenses, other than FAS pension costs, not considered allowable or allocable under applicable CAS and FAR rules, and therefore not allocated to the segments, such as a portion of management and administration, legal, environmental, certain compensation and retiree benefits, and other expenses.
Sales
2012 Sales for 2012 decreased $1.2 billion, or 5 percent, as compared to 2011, reflecting lower sales in three of our four operating segments.
2011 Sales for 2011 decreased $1.7 billion, or 6 percent, as compared to 2010, reflecting lower sales at all four operating segments.

Operating Costs and Expenses
Operating costs and expenses are primarily comprised of labor, material, subcontractor, and overhead costs, and are generally allocated to contracts as they are incurred. In accordance with industry practice and the regulations that govern cost accounting requirements for government contracts, most general management and corporate expenses incurred at the segment and corporate locations are considered allowable and allocable costs. These general and administrative costs are generally allocated on a systematic basis to contracts in progress.
Operating costs and expenses consist of the following:

2012 – Product and service costs for 2012 decreased $1.1 billion, or 6 percent, as compared to 2011. The primary driver of the reduction in product and service costs was reduced volume at Electronic Systems, Information Systems and Technical Services. General and administrative expenses as a percentage of total sales increased to 9.7 percent in 2012, from 8.9 percent in 2011; the increase includes the impact of lower sales, higher indirect costs related to compensation accruals and cost classification changes to standardize cost accounting practices at one of our segments, as well as higher bid and proposal expenses.
2011 – Product and service costs for 2011 decreased $2.1 billion, or 9 percent, as compared to 2010. The primary driver of the reduction in product and service costs is reduced volume at all four of our segments, with Aerospace Systems, Information Systems and Technical Services driving the majority of the decrease. General and administrative expenses as a percentage of total sales was comparable at 8.9 percent.
For the product and service costs detail, see the Product and Service Analysis section that follows.
Operating Income
We define operating income as sales less operating costs and expenses, which includes general and administrative expenses. Changes in estimated sales, operating costs and expenses, and the resulting operating income related to our contracts accounted for using the percentage-of-completion method are recorded using the cumulative catch-up method of accounting. The aggregate effects of these favorable and unfavorable changes in our estimated costs at completion, across our portfolio of contracts, can have a significant effect upon our reported sales and operating income in each of our reporting periods. Cumulative catch-up operating income adjustments are presented in the table below:

Cost reduction initiatives to increase our competitiveness contributed to the net favorable operating income adjustments. Our cost management activities have led to overall improved contract performance, reflected in both increased favorable adjustments and lower unfavorable adjustments.
Segment Operating Income
Segment operating income is defined as operating income less certain corporate-level expenses that are not considered allowable or allocable under applicable CAS and FAR and the net FAS/CAS pension difference.

2012 - Segment operating income in 2012 increased $121 million, or 4 percent, as compared to 2011, driven by a number of factors including improved performance, particularly at Electronic Systems. Improved performance reflects mitigation of contract risks and cost reduction initiatives, as well as portfolio shaping efforts. The increase in segment operating margin rate reflects this improved segment performance on lower revenue.
2011 - Segment operating income in 2011 increased $45 million, or 1 percent, as compared to 2010, driven by improved program performance, which more than offset the impact of lower sales.
Net Pension Adjustment
The net FAS/CAS pension adjustment in 2012 decreased $268 million, as compared to 2011, primarily due to increased GAAP pension expense resulting from amortization of prior year actuarial losses and decreased CAS pension expense allocated to the operating segments due to the design change in the company's defined benefit pension plans adopted in December 2011. The net FAS/CAS pension adjustment in 2011 increased $390 million, as compared to 2010, primarily due to decreased GAAP pension expense, primarily resulting from higher than estimated returns on a larger amount of pension plan assets as of the beginning of the year.
Unallocated Corporate Expenses
Unallocated corporate expenses for 2012 were comparable with the prior year. Unallocated corporate expenses for 2011 decreased $16 million, or 9 percent, as compared with 2010, primarily due to a decrease in stock-based compensation.
Interest Expense
Interest expense declined in both 2012 and 2011 by $9 million and $48 million, respectively, as compared to the respective prior years. The decrease from 2010 to 2011 is primarily due to a lower weighted average interest rate resulting from our debt refinancing in November 2010.
Federal and Foreign Income Taxes
2012 – Our effective tax rate on earnings from continuing operations for 2012 was 33.3 percent, as compared with 32.3 percent in 2011. The higher effective tax rate reflects the change in net tax benefits related to the absence of research tax credits, which expired at the end of 2011. Although the American Taxpayer Relief Act of 2012 extended the research tax credit through 2013, it was not enacted until January 2013. Therefore, the 2012 research credit will be recorded in the first quarter of 2013.
2011 – Our effective tax rate on earnings from continuing operations for 2011 was 32.3 percent, as compared with 19.5 percent in 2010. In 2010, we recognized net tax benefits of $298 million to reflect the final approval from the IRS and the U.S. Congressional Joint Committee on Taxation of the IRS’ examination of our tax returns for the years 2004 through 2006.
Diluted Earnings Per Share
2012 – Our diluted earnings per share increased by $0.29, or 4 percent. The higher diluted earnings per share reflects the full impact of 2011 share repurchases, which were largely purchased in the second half of 2011, the effect of our 2012 share repurchases and the higher segment operating income, partially offset by lower earnings reflecting the lower net FAS/CAS pension adjustment.
2011 – Our diluted earnings per share increased by $0.70, or 10 percent. The higher diluted earnings per share reflects higher earnings and the effects of our share repurchases.
Cash Provided by Continuing Operations
2012 – Cash provided by continuing operations for 2012 was $2.6 billion, as compared with $2.3 billion in 2011. Cash provided by continuing operations reflects lower pension contributions, partially offset by higher income taxes

paid. In 2012, we contributed $367 million to our pension plans, of which $300 million was voluntarily pre-funded, as compared with $1.1 billion in 2011, of which $1.0 billion was voluntarily pre-funded.
2011 – Cash provided by continuing operations in 2011 was $2.3 billion, as compared with $2.1 billion in 2010. The increase in 2011 reflects lower tax payments, timing of trade working capital and higher pension contributions. In 2011, we contributed $1.1 billion to our pension plans, of which $1.0 billion was voluntarily pre-funded, as compared with $789 million in 2010, of which $728 million was voluntarily pre-funded.
SEGMENT OPERATING RESULTS
Basis of Presentation
We are aligned in four reportable segments: Aerospace Systems, Electronic Systems, Information Systems and Technical Services. This section discusses sales, segment operating income and operating margin rates by segment. The reconciliation of segment sales to total sales is provided in Note 4 to the consolidated financial statements in Part II, Item 8, with the difference being intersegment sales eliminations. The reconciliation of segment operating income to total operating income, as well as a discussion of the reconciling items, is included in the Consolidated Operating Results section above. For purposes of the discussion in this Segment Operating Results section, references to operating income and operating income margin rate reflect segment operating income and segment operating margin rate.
On January 1, 2012, we transferred our missile business (primarily the Intercontinental Ballistic Missile (ICBM) program) from the Aerospace Systems segment to our Technical Services segment. The segment sales and segment operating income for the years ended December 31, 2011 and 2010, have been recast to reflect the missile business transfer. Sales of $494 million and $474 million, and segment operating income of $44 million and $43 million, were transferred from Aerospace Systems to Technical Services for the years ended December 31, 2011 and 2010, respectively.
For a more complete description of each segment’s products and services, see the business descriptions in Part I, Item 1.

2012 - Aerospace Systems sales for 2012 were comparable to the prior year. Sales of unmanned systems increased approximately $280 million, primarily related to ramping up on the NATO Alliance Ground Surveillance (AGS) and Fire Scout programs. Additionally, there was higher volume of approximately $200 million on the F-35 program due to deliveries on LRIP 5, the first F-35 contract accounted for under the units-of-delivery method. These increases were offset by the termination of a weather satellite program, which reduced sales by approximately $175 million, as well as lower sales on the Joint Surveillance Target Attack Radar System (JSTARS), F/A-18 and certain restricted space programs.
Operating income and margin rate for 2012 were comparable to the prior year. The operating income and margin rate reflect approximately $90 million lower operating income from the F/A-18 program's lower volume and transition from the multi-year 2 contract to the lower margin multi-year 3 contract, principally offset by performance improvements in space systems and higher margin rates and volume on sales of unmanned systems.
2011 - Aerospace Systems sales for 2011 decreased $472 million, or 5 percent, as compared with 2010. The decrease was primarily due to approximately $430 million lower sales in space systems due to reduced funding for weather satellite programs and the James Webb Space Telescope (JWST), as well as lower volume for several other space programs. Military aircraft systems declined approximately $130 million primarily due to lower volume on the F-35 program, which transitioned to a units-of-delivery revenue recognition method beginning with low rate initial production lot 5, the completion of the aerial targets program and lower volume on EA-18G Growler, offset by higher volume on Long Endurance Multi-Intelligence Vehicle (LEMV) and JSTARS. These decreases were partially offset by higher sales at advanced concepts and technology, primarily due to increased volume on restricted programs.

Operating income for 2011 was comparable with the prior year, and operating margin rate increased to 12.2 percent from 11.6 percent. The increase is primarily due to improved performance across several programs at Aerospace Systems and lower amortization expense on purchased intangibles, partially offset by an unfavorable adjustment for performance incentives on a space program and overall lower sales volume discussed above.

2012 - Electronic Systems sales for 2012 decreased $422 million, or 6 percent, as compared with 2011. The decrease was largely due to lower volume of approximately $160 million on infrared countermeasures sales and approximately $250 million lower postal automation sales, including approximately $150 million from our decision to de-emphasize our domestic postal automation business. These declines, as well as declines due to troop draw down and reduced overseas contingency operations funding, were partially offset by approximately $190 million higher volume on space programs.
Operating income for 2012 increased $117 million, or 11 percent, and operating margin rate increased to 17.1 percent from 14.5 percent. The higher operating income and operating margin rate reflect approximately $160 million of additional performance improvements over 2011, primarily on several combat avionics programs. These performance improvements include the effect of unfavorable adjustments of approximately $50 million on a domestic postal automation program in the prior year that did not recur in 2012.
2011 - Electronic Systems sales for 2011 decreased $241 million, or 3 percent, as compared with 2010. The decrease was primarily due to fewer deliveries on the Large Aircraft Infrared Countermeasures and Vehicular Intercommunications Systems (VIS) programs, offset by increased volume on restricted programs.
Operating income for 2011 increased $47 million, or 5 percent, and operating margin rate increased to 14.5 percent from 13.4 percent. The higher operating income is primarily due to performance improvements on several contracts nearing completion in Land & Self Protection Systems and Intelligence, Surveillance & Reconnaissance programs. The improved program performance was partially offset by reserves established in 2011 for reductions in workforce and a reserve on a program related to outstanding contractual issues as the contract nears completion and the overall lower sales volume described above.

2012 - Information Systems sales for 2012 decreased $565 million, or 7 percent, as compared with 2011, with no single program driving a significant portion. The decline in sales reflects the termination or wind-down on a number of programs, including the Joint Tactical Radio Systems Airborne, Maritime and Fixed (JTRS AMF), Installation Kits (I-KITS), Enterprise Network Management (ENM) and F-22 programs, partially offset by higher volume of approximately $110 million on the Encore II Information Technology support program, as well as higher volume on the Air and Space Operations Center, Enterprise System Development, and Ground Combat Vehicle programs. Further reducing sales was lower volume on restricted programs, as well as the sale of the County of San Diego IT outsourcing contract and the sale of Park Air Norway, which together reduced sales by approximately $100 million, as compared to 2011.
Operating income for 2012 decreased $5 million, or 1 percent, and operating margin rate increased to 10.3 percent from 9.7 percent. The higher operating margin rate is primarily driven by performance improvements across a number of contracts, which largely offset the impact of lower volume on operating income.
2011 - Information Systems sales for 2011 decreased $474 million, or 6 percent, as compared with 2010. The largest driver was lower sales for defense programs of $327 million, principally attributed to reduced volume on Force

Protection Security System, Saudi Arabian American Oil Company, Netcents DKO, F-22 and several other programs, partially offset by higher volume on Encore II and Trailer Mounted Support System programs. The lower civil sales volume is primarily due to the sale of the County of San Diego contract, which reduced sales by $70 million as compared to the same period in 2010, lower volume on the ENM program and completion of the Treasury Communications System program in 2010.
Operating income for 2011 increased $10 million, or 1 percent, and operating margin rate increased to 9.7 percent from 9.0 percent. The increase is primarily driven by improved performance on several civil programs, including the Virginia Information Technologies Agency Outsource contract and the effect of the sale of the County of San Diego contract, partially offset by the lower sales volume in defense programs described above.

2012 - Technical Services sales for 2012 decreased $174 million, or 5 percent, as compared with 2011. The decrease was primarily due to reduced volume from portfolio shaping of approximately $70 million as we focus our operations into core areas, lower KC-10 logistics activity of approximately $60 million and lower ICBM logistics and modernization activity of approximately $50 million.
Operating income for 2012 increased $8 million, or 3 percent, and operating margin rate increased to 8.9 percent from 8.1 percent. The higher operating income and operating margin rate were primarily due to improved performance on the KC-10 program, partially offset by lower sales volume as described above.
2011 - Technical Services sales for 2011 decreased $512 million, or 14 percent, as compared with 2010. The decrease is primarily due to $606 million lower sales in defense and government systems, primarily due to the reduced participation in the NSTec joint venture. Effective January 1, 2011, the company reduced its participation in this joint venture and deconsolidated it, resulting in no sales recorded for the joint venture for 2011, compared with sales of $579 million in 2010. The decrease was partially offset by increased activity on the KC-10 program, which began in February 2010.
Operating income for 2011 increased $11 million, or 4 percent, and operating margin rate increased to 8.1 percent from 6.7 percent. The increase in operating margin rate is primarily due to effects of the change in participation in the NSTec joint venture and performance improvements on several logistics and modernization and defense programs, partially offset by unfavorable program performance on KC-10.

The reconciliation of segment operating income to total operating income, as well as a discussion of the reconciling items, is included in the Consolidated Operating Results — Operating Income section above.
Product Sales and Product Costs
2012 - Product sales in 2012 decreased by $733 million, compared to 2011, primarily due to lower product sales at Electronic Systems and Technical Services, partially offset by higher product sales at Information Systems. The decrease at Electronic Systems primarily relates to lower volume of approximately $90 million in combat avionics and approximately $250 million in domestic and international postal automation programs. The decline at Technical Services was due to the change in classification of the ICBM program from product to service at the beginning of 2012, as the program transitioned from modernization to predominantly sustainment services. The increase at Information Systems was primarily driven by higher intercompany volume.
Product costs in 2012 decreased by $725 million, compared to 2011, primarily due to lower sales volume and increased performance improvement adjustments at Electronic Systems and the change in classification of the ICBM program at Technical Services, offset by higher product volume at Information Systems, as described above.
2011 - Product sales in 2011 decreased $1.0 billion, compared to 2010, primarily due to lower sales volume on space and military aircraft programs at Aerospace Systems and lower sales volume in Land and Self Protection Systems at Electronic Systems.

Product costs in 2011 decreased by $981 million, compared to 2010, due to the decline in sales volume. Specifically, Aerospace Systems sales decreased by approximately $600 million due to declines in space and military aircraft programs, partially offset by sales increases in advanced concepts and technology.
Service Sales and Service Costs
2012 - Service sales in 2012 decreased $415 million, compared to 2011, primarily due to lower service sales at Information Systems across a number of programs, partially offset by the transitioning of the ICBM program from product to service at Technical Services and higher service volume at Electronic Systems.
Service costs in 2012 decreased $544 million, due to lower sales at Information Systems, partially offset by the transitioning of the ICBM program from product to service at Technical Services, as described above, and higher service volume at Electronic Systems. The service activities at Aerospace Systems and Electronic Systems were at higher margin than the prior year, resulting in service costs decreasing more than service sales.
2011 - Service sales in 2011 decreased $684 million, compared to 2010, primarily due to the reduced participation by Technical Services in the NSTec joint venture, resulting in no sales recorded for the joint venture in 2011, compared to $579 million in 2010, and lower sales volume on defense and civil programs at Information Systems.
Service costs in 2011 decreased $790 million, due to the overall decline in sales for the period and margin rate improvements at Information Systems, Technical Services and Electronic Systems, offset somewhat by an unfavorable margin rate change at Aerospace Systems. Contributing to the overall decline in revenues was the company's reduced participation in the NSTec joint venture, which resulted in the deconsolidation of this business in 2011. NSTec contributed revenues of $579 million and segment cost of sales of $559 million in 2010 when it was included in Technical Service's sales, thus driving a 80 basis point improvement in margin rate for this segment. More modest margin rate improvements at Electronic Systems and Information Systems effectively offset the decline in margin rate at the Aerospace Systems business.
BACKLOG
Total backlog includes both funded backlog (firm orders for which funding is contractually obligated by the customer) and unfunded backlog. Unexercised contract options and indefinite delivery indefinite quantity (IDIQ) contracts are not included in backlog until the time the option or IDIQ task order is exercised or awarded. For multi-year service contracts with non-U.S. Government customers having no stated contract values, backlog includes only the amounts committed by the customer. Backlog is converted into sales as costs are incurred or deliveries are made.
On January 1, 2012, the company transferred its missile business, previously reported in Aerospace Systems to Technical Services. As a result of this realignment, $599 million of backlog was transferred from Aerospace Systems to Technical Services. Total backlog as of December 31, 2011, reflects this transfer.
Backlog consisted of the following at December 31, 2012 and 2011:

Approximately $21.4 billion of the $40.8 billion total backlog at December 31, 2012, is expected to be converted into sales in 2013. Total U.S. Government orders, including those made on behalf of foreign governments, comprised 82 percent of the total backlog at the end of 2012. International orders accounted for 12 percent of the total backlog at the end of 2012. Domestic commercial backlog represented 6 percent of total backlog at the end of 2012.
New Awards
2012The estimated value of contract awards booked during 2012 is $26.5 billion. Significant new awards during 2012 include $1.7 billion for the NATO AGS Unmanned System program, $1.4 billion for the JWST program, $1.3 billion for the F-35 program, $1.2 billion for the E-2D Advanced Hawkeye program, $1.0 billion for international air defense programs and $689 million for the Global Hawk program.

2011 -The estimated value of contract awards added to backlog during the year ended December 31, 2011, is $25.3 billion. Significant new awards in 2011 included $2.0 billion for the F/A-18 program, $1.1 billion for the E-2D Advanced Hawkeye program, $1.0 billion for the Global Hawk program, $1.1 billion for the B-2 program, $886 million for the F-35 program and $404 million for the KC-10 program.
LIQUIDITY AND CAPITAL RESOURCES
We endeavor to ensure the most efficient conversion of operating earnings into cash for deployment in our business and to maximize shareholder value. In addition to our cash position, we use various financial measures to assist in capital deployment decision-making, including, but not limited to, net cash provided by operations, free cash flow, net debt-to-equity and debt-to-capital. We believe these measures are useful to investors in assessing our financial performance and condition.
Cash balances and cash generated from continuing operations, supplemented by borrowings under credit facilities and/or in the capital markets, if needed, is expected to be sufficient to fund our operations for at least the next 12 months. As of December 31, 2012, the amount of cash, cash equivalents, and marketable securities held outside of the U.S. by foreign subsidiaries was $580 million. We do not anticipate repatriating these balances to fund domestic operations. Capital expenditure commitments at December 31, 2012, of approximately $258 million are expected to be paid with cash on hand.

Free Cash Flow from Continuing Operations
Free cash flow from continuing operations is defined as cash provided by operating activities from continuing operations less capital expenditures. We believe free cash flow from continuing operations is a useful measure for investors to consider as it represents the cash flow the company has available after capital spending to invest for future growth, strengthen the balance sheet and/or return to shareholders through dividends and share repurchases. Free cash flow is a key factor in our planning for and consideration of strategic acquisitions, the payment of dividends and stock repurchases.
Free cash flow from continuing operations is not a measure of financial performance under GAAP, and may not be defined and calculated by other companies in the same manner. This measure should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating results presented in accordance with GAAP as indicators of performance.

NORTHROP GRUMMAN CORPORATION                        

Operating Activities
2012 – Cash provided by continuing operations in 2012 increased $293 million, as compared to 2011, primarily due to lower pension contributions, partially offset by higher income taxes paid. In 2012, we contributed $367 million to our pension plans, of which $300 million was voluntarily pre-funded, as compared with $1.1 billion in 2011, of which $1.0 billion was voluntarily pre-funded.
2011 – Cash provided by continuing operations in 2011 increased $291 million, as compared to 2010, primarily due to lower tax payments and changes in trade working capital, partially offset by higher pension plan contributions. In 2011, pension plan contributions totaled $1.1 billion, of which $1 billion was voluntarily pre-funded. In 2010, pension plan contributions totaled $789 million, of which $728 million was voluntarily pre-funded.
Investing Activities
2012 – Cash used in investing activities from continuing operations in 2012 decreased $827 million, as compared to the cash provided by investing activities in 2011, reflecting a $1.4 billion contribution received from the spin-off of Shipbuilding business in 2011, partially offset by $250 million in proceeds from the maturity of short-term investments in 2012 that were purchased in 2011.
2011 – Cash provided by investing activities from continuing operations increased $1.3 billion as compared to 2010, reflecting a $1.4 billion contribution received from the spin-off of Shipbuilding business, partially offset by $250 million net purchases of a short-term investment in 2011.
Financing Activities
2012 – Net cash used in financing activities from continuing operations in 2012 decreased $1.8 billion, as compared to 2011, reflecting approximately $980 million lower repurchases of common stock and $768 of debt repayments in 2011 that did not recur in 2012.
2011 – Net cash used in financing activities from continuing operations in 2011 increased $2.4 billion, as compared to 2010, reflecting approximately $1.1 billion higher repurchases of common stock and $1.5 billion of debt proceeds in 2010.
Credit Facilities
In September 2011, the company entered into two senior unsecured credit facilities (the Credit Agreements) in an aggregate principal amount of $2 billion. The first Credit Agreement is for $1.5 billion with a maturity date of September 2016. The second Credit Agreement was a 364-day revolving credit facility in an aggregate principal amount of $500 million. In September 2012, the company entered into a new 364-day revolving credit facility in an aggregate principal amount of $500 million, replacing the previous $500 million 364-day revolving credit facility.
The Credit Agreements contain covenants which restrict the company’s ability to sell all or substantially all of its assets, merge or consolidate with another entity or undertake other fundamental changes and incur liens. The company also cannot permit the ratio of its consolidated debt to capitalization (as set forth in the Credit Agreements) to exceed 65 percent. The company is in compliance with all covenants under the Credit Agreements. At December 31, 2012, there was no balance outstanding under either of these credit facilities.
Other Sources and Uses of Capital
Additional Capital – We believe we can obtain additional capital, if necessary for long-term liquidity, from such sources as the public or private capital markets, the sale of assets, sale and leaseback of operating assets, and leasing rather than purchasing new assets. We have an effective shelf registration statement on file with the SEC, which allows us to access capital in a timely manner.
Financial Arrangements – In the ordinary course of business, the company uses standby letters of credit and guarantees issued by commercial banks and surety bonds issued principally by insurance companies to guarantee the performance on certain obligations. At December 31, 2012, there were $193 million of stand-by letters of credit, $295 million of bank guarantees, and $168 million of surety bonds outstanding.

A “purchase obligation” is defined as an agreement to purchase goods or services that is enforceable and legally binding on us and that specifies all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum, or variable price provisions; and the approximate timing of the transaction. These amounts are primarily comprised of open purchase order commitments to vendors and subcontractors pertaining to funded contracts.
(2)
Other long-term liabilities primarily consist of total accrued environmental reserves, deferred compensation, and other miscellaneous liabilities, of which $88 million is related to environmental reserves recorded in other current liabilities. It excludes obligations for uncertain tax positions of $175 million, as the timing of such payments, if any, cannot be reasonably estimated.
Further details regarding long-term debt and operating leases can be found in Notes 10 and 12, respectively, to the consolidated financial statements in Part II, Item 8.
CRITICAL ACCOUNTING POLICIES, ESTIMATES, AND JUDGMENTS
Revenue Recognition
Overview – We derive the majority of our business from long-term contracts for development, production and support activities for the U.S. Government. These contracts are accounted for in conformity with GAAP for construction-type and production-type contracts and federal government contractors, generally using the percentage-of-completion method accounting. We classify contract revenues as product or service depending on the predominant attributes of the contract. We consider the nature of these contracts and the types of products and services provided when determining the proper accounting method for a particular contract.
Percentage-of-Completion Accounting – The use of the percentage-of-completion method requires us to make reasonably dependable estimates for the design, manufacture, and delivery of our products and services. We generally recognize revenues from our long-term contracts under the cost-to-cost or the units-of-delivery measures of the percentage-of-completion method of accounting. The percentage-of-completion method recognizes revenue as work on a contract progresses. Most of our contracts use the cost-to-cost method, where revenue is calculated based on the percentage of total costs incurred in relation to total estimated costs at completion of the contract. The units-of-delivery measure recognizes revenues as deliveries are made to the customer, generally using unit sales values. Under both of these methods of percentage-of-completion accounting, we estimate profit as the difference between total estimated revenue and total estimated cost of a contract at completion, and recognize that profit as costs are incurred or as units are delivered.
Certain contracts contain provisions for price redetermination or for cost and/or performance incentives. These amounts are included in sales when they are reasonably estimable. Amounts representing un-priced change orders, claims, requests for equitable adjustment, or recovery of costs in excess of limitations in funding are included in estimated contract revenue only when they are reliably estimable and realization is probable. Changes in estimates of contract revenues, costs, or profits are recognized using the cumulative catch-up method of accounting. This method recognizes, in the current period, the cumulative effect of the changes on current and prior periods. Revenue and profit on future periods of contract performance are recognized as if the revised estimate had been used since contract inception. If it is determined that a loss will result from the performance of a contract, the entire amount of the estimable future loss is charged against income in the period the loss is identified. Loss provisions are first offset against costs that are included in unbilled accounts receivable or inventoried costs, and any remaining amount is reflected in liabilities.

NORTHROP GRUMMAN CORPORATION                        

Changes in contract estimates occur for a variety of reasons, including changes in contract scope, changes in estimated revenue, and changes in contract cost estimates. These changes are often driven by events such as changes in estimated incentive fees, unanticipated risks affecting contract costs, the resolution of risk at lower or higher cost than anticipated, and changes in indirect cost allocations, such as overhead and general and administrative expenses. We employ an extensive contract management process involving several functional organizations and numerous personnel who are skilled at managing contract activities. Changes in estimates are frequent; the company performs on a broad portfolio of long-term contracts, many of which include complex and customized aerospace and electronic equipment and software, that often includes technology at the forefront of science. Significant changes in estimates on a single contract could have a material effect on the company's consolidated financial position or annual results of operations, and where such changes occur, separate disclosure is made of the nature, underlying conditions and financial impact of the change. For the impacts of changes in estimates on our consolidated statement of earnings, see the Consolidating Operating Results section above and Note 1 to the consolidated financial statements in Part II, Item 8.
Cost Estimation – The cost estimation process is based on the professional knowledge of our engineers, program managers and financial professionals, and draws on their significant experience and judgment. Such costs are typically incurred over a period of several years, and estimation of these costs requires the use of judgment. Factors that are considered in estimating the cost of the work to be completed include the availability, productivity and cost of labor, the nature and complexity of the work to be performed, the effect of change orders, the availability and cost of materials, the effect of any delays in performance, and the level of indirect cost allocations. We update our contract estimates at least annually and more frequently as determined by the occurrence of events or changes in circumstances. We generally review and reassess our cost and revenue estimates for each significant contract on a quarterly basis.
Goodwill
Overview – We allocate the purchase price of acquired businesses to the underlying tangible and intangible assets acquired and liabilities assumed based upon their respective fair values, with the excess recorded as goodwill. Such fair value assessments require judgments and estimates that can be affected by contract performance and other factors over time, which may cause final amounts to differ materially from original estimates. Adjustments to the fair value of purchased assets and liabilities after the initial measurement period are recognized in net earnings.
Impairment Testing – We perform an annual impairment test of our goodwill as of November 30th, or between annual tests if events occur or circumstances change that suggest goodwill should be evaluated. When testing goodwill, we compare the fair value of each of our four reporting units to their carrying values.
To determine the fair value of our reporting units, we primarily use the income approach based on the cash flows that the reporting unit expects to generate in the future, consistent with our operating plans. This income valuation method requires management to project revenues, operating expenses, working capital, capital spending and cash flows for the reporting units over a multi-year period, as well as determine the weighted-average cost of capital (WACC) used as a discount rate and terminal value assumptions.
The WACC takes into account the relative weights of each component of our consolidated capital structure (equity and debt) and represents the expected cost of new capital adjusted as appropriate to consider lower risk profiles associated with longer-term contracts and barriers to market entry. The terminal value assumptions are applied to the final year of the discounted cash flow model. Impairment assessment inherently involves management judgments as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. Due to the many variables inherent in the estimation of a business’s fair value and the relative size of our recorded goodwill, differences in assumptions may have a material effect on the results of our impairment analysis.
We also corroborate the fair values determined under the income approach using the market valuation method to estimate the fair value of our reporting units, by utilizing industry multiples (including relevant control premiums) of operating earnings. If the carrying value exceeds the fair value, we determine the fair value of the reporting unit’s individual assets and liabilities and calculate the implied fair value of goodwill.
The results of our annual goodwill impairment test as of November 30, 2012, indicated that the estimated fair value of our reporting units exceed their carrying value. There were no impairment charges recorded in the years ended December 31, 2012, 2011 and 2010.
Fair values for three of our four reporting units substantially exceeded their respective carrying values as of our annual impairment testing on November 30, 2012. At our other reporting unit, Information Systems, fair value exceeds carrying value by approximately five percent. Information Systems carrying value includes goodwill of $5.3

billion as of December 31, 2012. We face continued uncertainty in our business environment due to the substantial fiscal and economic challenges facing the U.S. Government, our primary customer. Unresolved issues arising from these challenges include potential sequestration and action on the national debt ceiling. Potential contract cancellations or terminations may arise from resolution of these issues and could cause our revenues, profits and cash flows to be lower than our current projections. In addition, market-based inputs to the calculations in the impairment test, such as weighted average cost of capital and terminal value (based on market comparisons) could also be negatively impacted. Such circumstances may result in an impairment of our goodwill. Further, the carrying values of our reporting units are significantly influenced by a number of factors including the discount rate used to determine our net pension liability. Therefore, an increase in the discount rate on our pension liability in 2013 or beyond could result in an impairment of goodwill absent any changes discussed above. 
Retirement Benefits
Overview – For financial statement purposes, we account for our employee pension and other post-retirement plans in accordance with GAAP under FAS. We charge the costs of these plans to our contracts with customers in accordance with the FAR and the related CAS that govern such plans. In measuring periodic pension cost, both FAS and CAS recognize a normal service cost component, but there are differences in the way the remaining components of annual pension costs are calculated under each method, including the assumptions and methods used for measuring the plan obligations. As a result, retiree benefit plan expense amounts for FAS are different from the amounts for CAS. Further, differences result from dissimilar methodologies as to how estimated earnings on pension assets and interest expense on the pension obligations are measured, and the periods over which gains/losses related to pension assets and actuarial changes are amortized. CAS pension expense is charged to contracts and included in segment operating income, and the difference between the CAS and FAS pension expense is recorded in operating income at the consolidated company level.
For FAS purposes, we perform an annual review of the assumptions used in determining projected benefit obligations and the fair values of plan assets for our pension plans and other post-retirement benefit plans in consultation with our outside actuaries. In the event that we determine changes in the assumptions are warranted, or as a result of plan amendments, future FAS pension and post-retirement benefit expense could increase or decrease. The principal assumptions that have a significant effect on our consolidated financial position and results of operations are the discount rate, the expected long-term rate of return on plan assets, the health care cost trend rate and the estimated fair market value of plan assets.
Discount Rate – The discount rate represents the interest rate that is used to determine the present value of future cash flows currently expected to be required to settle the pension and other post-retirement benefit obligations. The discount rate is generally based on the yield of high-quality corporate fixed-income investments. At the end of each year, the discount rate is determined using a portfolio of high quality bonds matching the notional cash outflows related to benefit payments for each significant benefit plan. Taking into consideration the factors noted above, our weighted-average pension composite discount rate was 4.12 percent at December 31, 2012, and 5.03 percent at December 31, 2011.
The effects of hypothetical changes in the discount rate for a single year may not be representative and may be asymmetrical or nonlinear for future years because of the application of the accounting corridor. The accounting corridor is a defined range within which amortization of net gains and losses is not required. Holding all other assumptions constant, and since net actuarial gains and losses were in excess of the 10 percent accounting corridor in 2012, an increase or decrease of 25 basis points in the discount rate assumption for 2012 would have the following estimated effect to:

Expected Long-Term Rate of Return – The expected long-term rate of return on plan assets represents the average rate of earnings expected on funds invested. For 2012 and 2011, we assumed an expected long-term rate of return on plan assets of 8.25 percent and 8.5 percent, respectively. For 2013 pension and post-retirement benefit plan purposes, we have assumed an expected long-term rate of return on plan assets of 8.0 percent and 7.33 percent,

respectively. Holding all other assumptions constant, an increase or decrease of 25 basis points in the expected long-term rate of return assumption for 2012 would have the following estimated effect to:

Health Care Cost Trend Rate – The health care cost trend rate represents the annual rate of change in the cost of health care benefits based on external estimates of health care inflation, changes in health care utilization or delivery patterns, technological advances, and changes in the health status of the plan participants. For the years ended December 31, 2012 and December 31, 2011, we used a combination of market expectations and economic projections, including the effect of health care reform, to select an expected initial health care cost trend rate of 7 percent for 2013 and 7.5 percent for 2012, respectively. Additionally, we expect an ultimate health care cost trend rate of 5 percent to be reached in 2017 for both 2012 and 2011. Although our actual cost experience is much lower at this time, market conditions and the potential effects of health care reform are expected to increase medical cost trends in the next one to three years, thus our past experience may not reflect future conditions.
A one percentage-point change in the initial through the ultimate health care cost trend rates within the range would have had the following estimated effect on 2012 post-retirement benefit results:

Estimated Fair Market Value of Plan Assets – For certain plan assets where the fair market value is not readily determinable, such as real estate, private equity and hedge funds, estimates of fair value are determined using the best information available.
Litigation, Commitments, and Contingencies
We are subject to a range of claims, investigations, lawsuits, environmental matters, income tax matters, and administrative proceedings that arise in the ordinary course of business. Estimating liabilities and costs associated with these matters requires judgment based upon the professional knowledge and experience of management and counsel. We determine whether to record a charge to earnings and, if so, what amount based on consideration of the facts and circumstances of each matter as then known to us, including any settlement offers, and our assessment of the probability of the liabilities and whether the amount of the loss can be reasonably estimated. When we believe, based on the facts available to us, that a liability is probable and the loss is reasonably estimable, we record our best estimate of the amount of the ultimate loss. When a range of costs is reasonably estimable, but no amount within that range is a better estimate than another, we record what we estimate as the lower end of the range. Determinations whether to record a charge and, if so, of what amount, reflect management's assessment regarding what is likely to occur; they do not necessarily reflect what management believes should occur. The ultimate resolution of any such exposure to us may vary materially from earlier estimates as further facts and circumstances develop or become known to us. For further information on the treatment of these contingencies, see Note 1, Note 11 and Note 12 to the consolidated financial statements in Part II, Item 8.
Environmental Accruals - We are subject to environmental laws and regulations in the jurisdictions in which we conduct operations. Factors that could result in changes to the assessment of probability, range of estimated costs, and environmental accruals include: modification of planned remedial actions, increase or decrease in the estimated time required to remediate, discovery of more or less extensive contamination than anticipated, results of efforts to involve other responsible parties, financial capabilities of other responsible parties, changes in laws and regulations or contractual obligations affecting remediation requirements or other obligations, and improvements in remediation technology.

OTHER MATTERS
Accounting Standards Updates
Accounting standards updates effective after December 31, 2012, are not expected to have a material effect on the company's consolidated financial position or results of operations.
Business Dispositions
There were no material business dispositions in 2012 or 2010, however, in 2011 we completed the spin-off to our shareholders of HII effective March 31, 2011. HII operates the business that was previously the Shipbuilding segment (Shipbuilding) of the company prior to the spin-off. The spin-off was the culmination of the company’s decision to explore strategic alternatives for Shipbuilding as it was determined to be in the best interests of shareholders, customers, and employees to allow both the company and Shipbuilding to pursue more effectively their respective opportunities to maximize value. We made a pro rata distribution to our shareholders of one share of HII common stock for every six shares of our common stock held on the record date of March 30, 2011, or 48.8 million shares of HII common stock. There was no gain or loss recognized by the company as a result of the spin-off transaction. In connection with the spin-off, HII issued senior notes and entered into a credit facility with third-party lenders, and HII used a portion of the proceeds of the notes and credit facility to fund a $1.4 billion cash contribution to us. Sales for Shipbuilding for the three months ended March 31, 2011, were $1.6 billion and sales for the year ended December 31, 2010, were $6.7 billion. The assets, liabilities and operating results of this business unit are reported as discontinued operations in the consolidated financial statements for all periods presented.
Discontinued Operations – Results of operations for Shipbuilding, and an adjustment to the gain on a previous divestiture, were as follows:

Item 7A. Quantitative and Qualitative Disclosures about Market Risk
Market Risk –We are exposed to market risk with respect to our portfolio of trading and available-for-sale marketable securities with a fair value of $262 million at December 31, 2012.
Interest Rate Risk – We are exposed to interest rate risk with respect to our holdings of cash and cash equivalents of $3.9 billion at December 31, 2012, and we are also exposed to interest rate risk on variable-rate short-term credit facilities for which there were no borrowings outstanding at December 31, 2012. At December 31, 2012, we have $3.9 billion of long-term debt, primarily consisting of fixed rate debt, with a fair value of approximately $4.8 billion.
Derivatives – We do not hold or issue derivative financial instruments for trading purposes. From time to time, we may enter into interest rate swap agreements to manage our exposure to interest rate fluctuations. At December 31, 2012, we have no interest rate swap agreements in effect.
Foreign Currency Risk – We are exposed to foreign currency risk with respect to our foreign operations. We enter into foreign currency forward contracts to manage a portion of the exchange rate risk related to receipts from customers and payments to suppliers denominated in foreign currencies. At December 31, 2012, foreign currency forward contracts with a notional amount of $144 million were outstanding.
Inflation Risk – We have generally been able to anticipate increases in costs when pricing our contracts. Bids for longer-term firm fixed-price contracts typically include labor and other cost escalations in amounts that historically have been sufficient to cover cost increases over the period of performance.
A 10 percent change in interest rates or foreign currency exchange rates would not have a material impact to our consolidated financial position or results of operations.

Item 8. Financial Statements and Supplementary Data
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of
Northrop Grumman Corporation
Falls Church, Virginia
We have audited the accompanying consolidated statements of financial position of Northrop Grumman Corporation and subsidiaries (the “Company”) as of December 31, 2012 and 2011, and the related consolidated statements of earnings and comprehensive income, changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2012. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Northrop Grumman Corporation and subsidiaries at December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012, in conformity with accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 4, 2013 expressed an unqualified opinion on the Company’s internal control over financial reporting.
