PART I


ITEM 1. BUSINESS

History and Organization

For more than a century, Huntington Ingalls Industries, Inc. ("HII", the "Company", "we", "us", or "our" and, as the context requires, including our predecessor business as a subsidiary of Northrop Grumman Corporation ("Northrop Grumman")) has been designing, building, overhauling, and repairing ships primarily for the U.S. Navy and the U.S. Coast Guard. We are the nation's sole designer, builder, and refueler of nuclear-powered aircraft carriers, a builder of amphibious assault and expeditionary warfare ships for the U.S. Navy, the sole builder of National Security Cutters ("NSCs") for the U.S. Coast Guard, one of only two companies currently designing and building nuclear-powered submarines for the U.S. Navy, and one of only two companies that builds the Navy's current fleet of DDG-51 Arleigh Burke-class destroyers. We are the exclusive provider of Refueling and Complex Overhaul ("RCOH") services for nuclear-powered aircraft carriers, a full-service systems provider for the design, engineering, construction, and life cycle support of major programs for surface ships, and a provider of fleet support and maintenance services for the U.S. Navy.
 
We conduct most of our business with the U.S. Government, principally the Department of Defense ("DoD"). As prime contractor, principal subcontractor, team member, or partner, we participate in many high-priority U.S. defense technology programs. We operate our shipbuilding business through our Huntington Ingalls Incorporated subsidiary, which is organized into two segments: Ingalls Shipbuilding ("Ingalls"), which includes our non-nuclear ship design, construction, repair, and maintenance businesses; and Newport News Shipbuilding ("Newport News"), which includes all of our nuclear ship design, construction, overhaul, refueling, and repair and maintenance businesses. We also provide a range of services to the energy and oil and gas industries, as well as government customers.
 
We became an independent, publicly-owned company on March 31, 2011, when we were spun off from Northrop Grumman. We have owned and operated the legacy Northrop Grumman shipbuilding business since the spin-off. We believe our product capabilities, heavy industrial facilities, and a workforce of approximately 36,000 employees position us well to continue to support the long-term objectives of the U.S. Navy and U.S. Coast Guard.

Ingalls
 
Through our Ingalls segment, we design and construct non-nuclear ships for the U.S. Navy and U.S. Coast Guard, including amphibious assault ships, surface combatants, and NSCs. We build amphibious assault ships for the U.S. Navy and have built 28 of the 62 DDG-51 Arleigh Burke-class of Aegis guided missile destroyers in active service. We are also the sole builder of the large multi-mission NSCs for the U.S. Coast Guard. Our Ingalls shipbuilding site is located in Pascagoula, Mississippi. This shipyard offers a collection of manufacturing capabilities that include a 660-ton gantry crane and a Land Based Test Facility.

In October 2014, we ceased shipbuilding construction operations at our Avondale, Louisiana shipyard ("Avondale") and consolidated that activity at our Pascagoula, Mississippi facility, which we believe enhances our competitive position by decreasing our fixed overhead expenses, improving facility utilization to provide a more cost-efficient construction process, centralizing our shipbuilding learning and increasing the benefits of serial production, and reducing program costs. In March 2015, we sold our Gulfport Composite Center of Excellence (the "Gulfport facility") in Gulfport, Mississippi, to the Mississippi State Port Authority, due to limited demand from the U.S. Navy for composite products provided by our Gulfport facility.

Amphibious Assault Ships
 
We supply the U.S. Navy with amphibious assault and expeditionary warfare ships, which include the U.S. Navy large deck amphibious ships ("LHA") and amphibious transport dock ships ("LPD"). The LHA is a key component of the U.S. Navy-Marine Corps requirement for 11 Expeditionary Strike Groups/Amphibious Readiness Groups, and design, construction, and modernization of LHAs are core to our Ingalls operations. In 2007, we were awarded the construction contract for LHA-6 America, the first in a new class of enhanced amphibious assault ships designed from the keel up to be an aviation optimized Marine assault platform. We delivered LHA-6 America in the second quarter of 2014 and are currently constructing LHA-7 Tripoli, scheduled for delivery in 2018.

1


 
The LPD program is a long-running production program in which we have generated efficiencies through ship-over-ship learning. We are currently constructing two LPD-17 San Antonio-class amphibious transport dock ships, LPD-26 John P. Murtha, scheduled for delivery in 2016, and LPD-27 Portland, scheduled for delivery in 2017. We delivered LPD-25 USS Somerset in 2013 and LPD-23 USS Anchorage and LPD-24 USS Arlington in 2012. In December 2015, we were awarded an advance procurement contract for LPD-28 (unnamed).

Surface Combatants
 
We are a design agent for and one of only two companies that constructs the DDG-51 Arleigh Burke-class guided missile destroyers. We have delivered 28 DDG-51 Arleigh Burke-class destroyers to the U.S. Navy. We are currently constructing DDG-113 John Finn and DDG-114 Ralph Johnson, scheduled for delivery in 2016 and 2017, respectively. In 2013, we were awarded a multi-year contract totaling $3.3 billion for construction of five additional DDG-51 Arleigh Burke-class destroyers as a part of a larger U.S. Navy order for nine DDG-51 Arleigh Burke-class destroyers. We began fabrication on DDG-117 Paul Ignatius in 2014 and DDG-119 Delbert D. Black in 2015, with deliveries scheduled in 2018 and 2019, respectively.

In 2008, the U.S. Navy truncated the DDG-1000 Zumwalt-class destroyer program when it restarted the DDG-51 Arleigh Burke-class destroyer production line. Our participation in the DDG-1000 Zumwalt-class program included detailed design and construction of the ships' integrated composite deckhouses and hangars, as well as portions of the ships' aft peripheral vertical launch systems. We completed our participation in this program with the delivery of the composite deckhouse of DDG-1001 Michael Monsoor in 2014.
 
National Security Cutters
 
The U.S. Coast Guard's recapitalization program is designed to replace aging and operationally expensive ships and aircraft used to conduct missions in excess of 50 miles from the shoreline. The flagship of this program is the Legend-class NSC, a multi-mission platform we designed and built. The U.S. Coast Guard ordered the first three NSC vessels from Integrated Coast Guard Systems ("ICGS"), a joint venture between Lockheed Martin and us. Beginning in 2010 with the construction contract for NSC-4 USCGC Hamilton, the NSC contracts have been awarded directly to us. NSC-4 USCGC Hamilton and NSC-5 USCGC James were delivered to the U.S. Coast Guard in 2014 and 2015, respectively. NSC-6 Munro and NSC-7 Kimball are currently under construction and are scheduled for delivery in 2016 and 2018, respectively. We were awarded the construction contract for NSC-8 Midgett in 2015, and it is scheduled for delivery in 2019.

Newport News

The capabilities of our Newport News segment extend from our core business of designing and constructing nuclear-powered ships, such as aircraft carriers and submarines, and the refueling and overhaul and the inactivation of such ships, to businesses that are focused on the construction of heavy manufacturing equipment for commercial nuclear power facilities and the operation, management, and cleanup of environmental hazard sites through Department of Energy ("DoE") programs. Our Newport News shipyard is one of the largest shipyards in the United States, located on approximately 550 acres near the mouth of the James River, which adjoins the Chesapeake Bay. The shipyard has two miles of waterfront property and heavy industrial facilities, which include seven graving docks, a floating dry dock, two outfitting berths, five outfitting piers, module outfitting facilities, and various other workshops. Our Newport News shipyard also has a 2,170-foot dry dock serviced by a 1,050-ton gantry crane capable of supporting two aircraft carriers at one time.
 
Design, Construction, and Refueling and Complex Overhaul of Aircraft Carriers

Engineering, design, and construction of U.S. Navy nuclear aircraft carriers are core to Newport News operations. Aircraft carriers are the largest ships in the U.S. Navy's fleet, with a displacement of over 90,000 tons. Newport News has delivered 30 aircraft carriers to the U.S. Navy since 1933, including all ten ships currently in active service.
 
We delivered the U.S. Navy's newest carrier and the last of the CVN-68 Nimitz-class, CVN-77 USS George H.W. Bush, in 2009. We have been engaged in design work on the next generation aircraft carrier, the CVN-78 Gerald R. Ford-class, for over ten years. In 2008, we were awarded a $5.1 billion contract for detail design and construction of the first ship of the class, CVN-78 Gerald R. Ford, which is scheduled for delivery in 2016. We also received awards

2


in 2009 through 2015 totaling $6.6 billion for construction preparation, detail design, and construction of the second CVN-78 Gerald R. Ford-class aircraft carrier, CVN-79 John F. Kennedy.
 
We continue to be the exclusive prime contractor for nuclear aircraft carrier RCOH. Each RCOH takes over three years to complete, and the work accounts for approximately 35% of all maintenance and modernization during an aircraft carrier's 50 year service life. RCOH services include propulsion work (refueling of reactors; propulsion plant modernization; and propulsion plant repairs), restoration of service life (dry docking, tank, and void maintenance; hull, shafting, propellers, and rudders; launch and recovery system; piping repairs; and component refurbishment), and modernization (electrical systems; aviation support systems; warfare; interoperability; and environmental compliance). We provide ongoing maintenance services for the U.S. Navy aircraft carrier fleet through both RCOH and on-site fleet repair work.

We completed the RCOH for CVN-71 USS Theodore Roosevelt and redelivered it to the U.S. Navy in 2013. We also received awards totaling $2.6 billion under an execution contract for the RCOH of CVN-72 USS Abraham Lincoln, which is scheduled for redelivery in 2016. We believe our position as the exclusive designer and builder of nuclear-powered aircraft carriers, as well as the fact that RCOH work requires a highly trained workforce, is capital-intensive, and has high barriers to entry due to its nuclear component, strongly position us for future RCOH contract awards on the U.S. Navy aircraft carrier fleet.
 
Aircraft Carrier Inactivation
 
The U.S. Navy awarded us a $745 million contract in 2013 to inactivate CVN-65 USS Enterprise, the world's first nuclear-powered aircraft carrier, which was built by us and commissioned in 1961. The CVN-65 USS Enterprise has a scheduled redelivery date in 2017. Aircraft carriers have a lifespan of approximately 50 years, and we believe the ten carriers delivered by us that are currently in active service, as well as those we will deliver in the future, present a significant opportunity for us with respect to their inactivation. We believe that the U.S. Navy will require inactivation of aircraft carriers in the naval fleet as they reach the end of their lifespans, and we intend to be positioned as the best choice for these contract awards.

Design and Construction of Nuclear-Powered Submarines
 
We are one of only two companies in the United States capable of designing and building nuclear-powered submarines for the U.S. Navy. Newport News has delivered 59 submarines to the U.S. Navy since 1960, comprised of 45 fast attack and 14 ballistic missile submarines. Of the 53 nuclear-powered fast attack submarines currently in active service, 26 were delivered by Newport News. Our nuclear submarine program, located at our Newport News shipyard, includes construction, engineering, design, research, and integrated planning.

In February 1997, we executed a teaming agreement with Electric Boat, a division of General Dynamics Corporation ("General Dynamics"), to build SSN-774 Virginia-class fast attack nuclear submarines cooperatively. Under the present arrangement, we build the stern, habitability and machinery spaces, torpedo room, sail, and bow, while Electric Boat builds the engine room, control room, and pressure hull structure. Work on the reactor plant and the final assembly, test, outfit, and delivery of the submarines alternate between Electric Boat and us.

The four submarines of the first block and six submarines of the second block of SSN-774 Virginia-class submarines have been delivered. In 2008, the team was awarded a construction contract for the third block of eight SSN-774 Virginia-class submarines. The multi-year contract increased construction from one submarine per year to two submarines per year from 2011 through 2013. The first submarine under this contract was delivered in 2014, the second was delivered in 2015, and the last submarine of the third block is scheduled for delivery in 2019. In 2014, the team was awarded a construction contract for the fourth block of ten SSN-774 Virginia-class submarines, continuing the two submarines per year production rate. The first submarine of the block IV contract is scheduled for delivery in 2019, and the last is scheduled for delivery in 2023.

Fleet Support: AMSEC and Continental Maritime of San Diego ("CMSD")
 
Fleet Support provides comprehensive life cycle services, including depot maintenance, modernization, repairs, logistics and technical support, and planning yard services for naval and commercial vessels through our AMSEC and CMSD subsidiaries. We have ship repair facilities in Newport News, Virginia, and San Diego, California, which are near the U.S. Navy's largest homeports of Norfolk, Virginia, and San Diego, respectively. AMSEC provides naval architecture and marine engineering, ship system assessments, maintenance engineering, and logistics services to the U.S. Navy and commercial maritime industry from 27 locations across the globe. On any given day, over 600 of our AMSEC employees are on board U.S. Navy ships, assessing equipment conditions, modernizing systems, and training sailors. Through CMSD, a Master Ship Repair contractor, we provide ship repair, regular overhaul, and selected restricted availability services (pier side or in customers' dry docks) for the U.S. Navy. We also perform emergent repair for the U.S. Navy on all classes of ships. Beginning in 2014, AMSEC and CMSD were transferred from the Ingalls segment to the Newport News segment.

SSBN(X) Ohio-Class Replacement Program
 
The U.S. Navy's shipbuilding plan for Fiscal Year 2015 states the U.S. Navy's intention to focus on the design and construction of replacement boats for the current aging Ohio-class nuclear ballistic and cruise missile submarines. The U.S. Navy has committed to designing a replacement class for the SSBN Ohio-class nuclear ballistic missile submarines ("SSBN"), which were first introduced into service in 1981. The SSBN Ohio-class includes 14 nuclear ballistic missile submarines and four nuclear cruise missile submarines ("SSGN"). The Ohio Replacement Program is a $100 billion program that currently anticipates 12 new ballistic missile submarines over a 15-year period at an annual budget of approximately $5 billion to $7 billion. The U.S. Navy has initiated the design process for the new class of submarine, and we have begun design work as a subcontractor to Electric Boat. We believe our experience and specialized workforce position us for a potential role in the construction effort. Congress has delayed the start of the first Ohio replacement submarine by two years, and construction is now expected to begin in 2021, with procurement of long-lead-time materials in 2017 and delivery in 2030. The first Ohio-class ballistic missile submarine is expected to be retired in 2027, with an additional submarine being retired each year thereafter. By 2030 the Ohio-class ballistic missile submarine fleet is expected to be down to ten. The current fiscal environment and uncertainty in defense budgets may cause additional delay to the start of construction or result in a reduction in the number of ships being procured, but we believe the Ohio Replacement Program may represent a significant opportunity for us in the future.
 
Energy
 
Our DoE and commercial nuclear programs leverage our core competencies in nuclear operations, program management, and heavy manufacturing. We selectively partner with experienced industry leaders, and we participate in active joint ventures. Through our subsidiary, Stoller Newport News Nuclear, Inc. ("SN3"), we provide technical, environmental, ecological, waste management, remediation, and consultation services to private sector companies and the DoE.

Newport News Industrial Corporation ("NNI") provides a range of support services to commercial nuclear power plants. Since it was founded in 1965, NNI has expanded its capabilities, continuing to provide support for nuclear energy facilities, as well as for fossil power plants and other industrial facilities. NNI focuses on fabrication services, construction services, equipment services, technical services, and product sales to its customers, which include both private industry and government entities such as the DoE and the DoD.

In January 2008, Savannah River Nuclear Solutions, LLC ("SRNS"), our joint venture with Fluor Federal Services, Inc. and Honeywell International Inc., was awarded a five-year $4 billion contract for site management and operations at the DoE's Savannah River Site located 12 miles south of Aiken, South Carolina, which would have expired in 2013. In 2012, the DoE exercised its option to extend the original contract for another three years through 2016. We have a 34% ownership interest in SRNS.

Other

Our Other segment was established in the second quarter of 2014 to account for certain of our non-shipbuilding commercial activities following our acquisition of UniversalPegasus International Holdings, Inc. ("UPI"). UPI has a 50 year history of providing project management, engineering, and construction management for the oil and gas industry. UPI has approximately 600 professionals, with major office locations in Houston, Texas; Calgary, Canada; Aberdeen, Scotland; and San Juan, Trinidad and Tobago.

Corporate

Huntington Ingalls Industries, Inc. was incorporated in Delaware on August 4, 2010. Our principal executive offices are located at 4101 Washington Avenue, Newport News, Virginia 23607. Our telephone number is (757) 380-2000, and our home page on the Internet is www.huntingtoningalls.com. References to our website in this report are provided as a convenience and do not constitute, and should not be viewed as, incorporation by reference of the information contained on, or available through, the website. Accordingly, such information should not be considered part of this report.

Summary Segment Financial Data

For a more complete understanding of our segment financial information, see Segment Operating Results in Item 7 and Note 9: Segment Information in Item 8.

Customers

Our revenues are primarily derived from the U.S. Government. In 2015, 2014, and 2013, approximately 89%, 88%, and 94%, respectively, of our revenues were generated from the U.S. Navy, and approximately 7%, 8%, and 6%, respectively, were generated from the U.S. Coast Guard. In 2015 and 2014, we generated approximately 3% and 2% of our revenues from commercial customers, respectively, and 1% and 2% from other government agencies, respectively.

Intellectual Property

We develop and incorporate into our vessels new technologies, manufacturing processes, and systems-integration practices. In addition to owning a large portfolio of proprietary intellectual property, we license intellectual property rights to and from others. The U.S. Government holds licenses to our patents developed in the performance of U.S. Government contracts and unlimited license rights in technical data developed under our U.S. Government contracts when such data is developed entirely at government expense. The U.S. Government may use or authorize others to use the technology covered by our patents licensed to the government. While our intellectual property rights are important to our operations, we do not believe that any existing patent, license, or other intellectual property right is of such importance that its loss or termination would have a material impact on our business.
    
Seasonality

No material portion of our business is seasonal. The timing of our revenue recognition is based on several factors, including the timing of contract awards, the incurrence of contract costs, contract cost estimation, and unit deliveries. See Critical Accounting Policies, Estimates, and Judgments - Revenue Recognition in Item 7.

Backlog

As of December 31, 2015 and 2014, our total backlog was approximately $22 billion and $21 billion, respectively. We expect approximately 29% of backlog at December 31, 2015, to be converted into sales in 2016.

Total backlog includes both funded backlog (firm orders for which funding is contractually obligated by the customer) and unfunded backlog (firm orders for which funding is not currently contractually obligated by the customer). Unfunded backlog excludes unexercised contract options and unfunded Indefinite Delivery/Indefinite Quantity ("IDIQ") orders. For contracts having no stated contract values, backlog includes only the amounts committed by the customer. Backlog is converted into sales as work is performed or deliveries are made. For backlog by segment, see Backlog in Item 7.

Raw Materials
 
The most significant material we use is steel. Other materials used in large quantities include paint, aluminum, pipe, electrical cable, and fittings. All of these materials are currently available in adequate supply. In connection with our U.S. Government contracts, we are required to procure certain materials and component parts from supply sources approved by the U.S. Government. Generally, for long-term contracts, we obtain price quotations for many of our materials requirements from multiple suppliers to ensure competitive pricing. We have not generally been dependent upon any one supply source; however, due to consolidation in the defense industry, we currently have only one supplier for certain component parts. We believe that these single source suppliers, as well as our overall supplier base, are adequate to meet our foreseeable needs. We have mitigated some supply risk by negotiating long-term agreements with certain raw material suppliers. In addition, we have mitigated price risk related to raw material purchases through certain contractual arrangements with customers.

Research and Development

To facilitate innovative product development and evolution, we conduct research and development activities as part of our normal business operations. Our research and development activities primarily include Independent Research and Development ("IR&D") related to government programs. We recover a significant portion of our IR&D expenditures through overhead charges to U.S. Government contracts, consistent with U.S. Government regulations. We include IR&D expenses in general and administrative expenses. Company-sponsored IR&D expenses totaled $19 million, $18 million, and $22 million for the years ended December 31, 2015, 2014, and 2013, respectively.
 
At our Virginia Advanced Shipbuilding and Carrier Integration Center ("VASCIC"), located in Newport News, Virginia, we conduct on-site warfare systems testing, training, and laboratory research for the next generation of aircraft carriers, submarines, and other ships. VASCIC serves as the focal point for the integration of ship systems and the application of new technologies. It has a classified facility and an integration area that facilitates research and development related to setup and testing of electronics, as well as hull, mechanical, and electrical systems, prior to introducing new equipment on board a ship. It also has modeling and simulation capability allowing for visualization using 3-D displays. We believe VASCIC benefits the U.S. Navy and represents a competitive advantage for us by developing future naval capabilities, reducing total ownership cost, and facilitating technology transfer.

Governmental Regulation and Supervision

Our business is affected by a variety of laws and regulations relating to the award, administration, and performance of U.S. Government contracts. See Risks Related to Our Business, in Risk Factors in Item 1A.

We operate in a heavily regulated environment and are routinely audited and reviewed by the U.S. Government and its agencies, including the U.S. Navy's Supervisor of Shipbuilding, the Defense Contract Audit Agency ("DCAA"), and the Defense Contract Management Agency ("DCMA"). These agencies review our contract performance, cost structures, and compliance with applicable laws, regulations, and standards, as well as the adequacy of, and our compliance with, our internal control systems and policies. Systems subject to audit or review include our accounting systems, purchasing systems, billing systems, property management and control systems, cost estimating systems, earned value management systems, compensation systems, and management information systems. If an audit uncovers improper or illegal activities, we may be subject to administrative, civil, or criminal proceedings, which could result in fines, penalties, repayments, or compensatory, treble, or other damages. Certain U.S. Government findings against a contractor can also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. In addition, any costs we incur that are determined to be unallowable or improperly allocated to a specific contract will not be reimbursed by a government customer or must be refunded if already reimbursed.

The U.S. Government has the ability to decrease or withhold contract payments if it determines significant deficiencies exist in one or more business systems subject to its review. The U.S. Government has, in certain instances, withheld payments on contracts upon its assessment that deficiencies exist with one or more of our business systems. When appropriate, we will modify our affected business systems to address the U.S. Government's concerns.
 

6


In addition, the U.S. Government generally has the ability to terminate contracts, in whole or in part, with little to no prior notice, for convenience or for default based on performance. In the event of termination for the government's convenience, contractors are generally protected by provisions that provide for reimbursement of costs already incurred on the contracts and profit on those costs up to the amount authorized under the contract, but not the anticipated profit that would have been earned had the contract been completed. Such a termination could also result in the cancellation of future work on the related program. Termination resulting from our default could expose us to various liabilities, including excess reprocurement costs, and could have a material effect on our ability to compete for future contracts.

Government contractors must comply with significant regulatory requirements, including those related to procurement. Our contracts with the U.S. Government may result in Requests for Equitable Adjustments ("REAs"), which represent requests for the U.S. Government to make appropriate adjustments to terms of a contract, including pricing, delivery schedule, technical requirements, or other affected terms, due to changes in the original contract requirements and resulting delays and disruption in contract performance for which the U.S. Government is responsible. We prepare, submit, and negotiate REAs in the ordinary course of business, and large REAs are not uncommon at the conclusion of both new construction and RCOH activities. Such REAs are not considered claims under the Contract Disputes Act of 1978, although they may be converted to such claims if good faith negotiations to resolve the REAs are not satisfactory.
 
In cases where there are multiple suppliers, contracts for the construction and conversion of U.S. Navy ships and submarines are generally subject to competitive bidding. In evaluating proposed prices, the U.S. Navy sometimes requires that each bidder submit information on pricing, estimated costs of completion, and anticipated profit margins in order to assess cost realism. The U.S. Navy uses this information and other data to determine an estimated cost for each bidder. Under U.S. Government regulations, certain costs, including certain financing costs and marketing expenses, are not allowable contract costs and, therefore, are not recoverable. The U.S. Government also regulates the methods by which all costs, including overhead, are allocated to government contracts.
 
Our business, our contracts with various agencies of the U.S. Government, and our subcontracts with other prime contractors are subject to a variety of laws and regulations, including, but not limited to, the Federal Acquisition Regulation ("FAR"), the Truth in Negotiations Act, the Procurement Integrity Act, the False Claims Act, Cost Accounting Standards, 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. A noncompliance determination by a government agency may result in reductions in the values of contracts, contract modifications or terminations, penalties, fines, repayments, compensatory, treble, or other damages, or suspension or debarment.

Competition

In our primary business of designing, building, overhauling, and repairing military ships, we primarily compete with General Dynamics and, to a lesser extent, smaller shipyards, one or more of which could team with a large defense contractor. Intense competition related to programs, resources, and funding, and long operating cycles are key characteristics of both our business and the shipbuilding defense industry in general. It is common industry practice to share work on major programs among a number of companies. A company competing to be a prime contractor may, upon ultimate award of the contract to another party, become a subcontractor for the prime contracting party. It is not uncommon to compete for a contract award with a peer company and, simultaneously, perform as a supplier to or a customer of such competitor on other contracts. The nature of major defense programs, conducted under binding contracts, allows companies that perform well to benefit from a level of program continuity not common in many industries.

We believe we are well-positioned in the market. Because we are the only company currently capable of building, refueling, and defueling the U.S. Navy's nuclear-powered aircraft carriers, we believe we are in a strong competitive position to be awarded each contract to perform such activities. Even so, the government periodically revisits whether refueling of nuclear-powered aircraft carriers should be performed in private or public facilities. In this regard, the National Defense Authorization Act for Fiscal Year 2012 ("2012 Act") required DoD to develop a core depot level maintenance capability to refuel nuclear aircraft carriers. The National Defense Authorization Act for Fiscal Year 2013 ("2013 Act") modified the 2012 Act by restoring an exception for the nuclear refueling of an aircraft carrier from the definition of core depot level maintenance. The 2013 Act also amended and clarified the exception to cover the concurrent refueling and overhaul of an aircraft carrier, as well as the defueling of an aircraft carrier.

Similarly, the 2013 Act restored an exclusion for nuclear aircraft carrier programs from the definition of core logistics capabilities that was found in previous law.

We are currently the only builder of large deck amphibious assault and expeditionary warfare ships for the U.S. Navy, including LHAs and LPDs. We are, however, currently engaged in a competition to build either the next amphibious assault ship ("LHA-8") or six fleet oilers ("T-AO(X)"). We are also the sole builder of NSCs for the U.S. Coast Guard, and are positioned to be awarded future contracts for these types of vessels. We are one of only two companies currently designing and building nuclear-powered submarines for the U.S. Navy, and we are party to a long-term teaming agreement with the other company for the production of such vessels. We are one of only two companies that builds the U.S. Navy's current fleet of DDG-51 Arleigh Burke-class destroyers and are positioned to be awarded future contracts for these types of ships as well.

Our success in the shipbuilding defense industry depends upon our ability to develop, market, and produce our products and services at a cost consistent with the U.S. Navy's budget, as well as our ability to provide the workforce, technologies, facilities, equipment and financial capacity needed to deliver those products and services with maximum efficiency.

We compete with a variety of companies in the provision of engineering services in the energy and oil and gas markets.

Environmental, Health, and Safety

Our manufacturing operations are subject to and affected by federal, state, and local laws and regulations relating to the protection of the environment. We accrue the estimated costs to complete environmental remediation when we determine it is probable we will incur expenses in the future, in amounts we can reasonably estimate, to address environmental conditions at currently or formerly owned or leased operating facilities, or at sites where we are named a Potentially Responsible Party ("PRP") by the U.S. Environmental Protection Agency ("EPA") or similarly designated by another environmental agency. The inherent difficulties in estimating future environmental remediation costs, resulting from uncertainties regarding the extent of required remediation, determination of legally responsible parties, and the status of laws and regulations and their interpretations, can cause our estimated remediation costs to change.

We assess the potential impact on our financial statements of future environmental remediation costs by estimating, on a site-by-site basis, the range of reasonably possible remediation costs that we could incur, taking into account currently available information at each site, the current state of technology, and our prior experience in remediating contaminated sites. We review our estimates periodically and adjust them to reflect changes in facts, technology, and legal circumstances. We record accruals for environmental remediation costs on an undiscounted basis in the accounting period in which it becomes probable we have incurred a liability and the costs can be reasonably estimated. We would record related insurance recoveries only when we determine that collection is probable, and we do not include any litigation costs related to environmental matters in our environmental remediation accrual.

We either expense or capitalize environmental expenditures as appropriate. Capitalized expenditures relate to long-lived improvements in current operating facilities. We accrue environmental remediation costs at sites involving multiple parties based upon our expected share of liability, taking into account the financial viability of other jointly liable parties. We may incur remediation costs exceeding our accrued amount if other PRPs do not pay their allocable share of remediation costs, which could have a material effect on our business, financial position, results of operations, or cash flows.

As of December 31, 2015, our probable future costs for environmental remediation were approximately $2 million, which is accrued in other current liabilities in the consolidated statement of financial position. Although information gained as projects progress may materially affect our accrued liability, we do not anticipate that future remediation expenditures will have a material effect on our financial position, results of operations, or cash flows.

We may incur environmental costs in the future related to our wind down of shipbuilding at Avondale. These costs are not reasonably estimable at this time due to insufficient information about the nature, timing, and extent of any potential environmental remediation we may be required to perform or the related costs that we may incur. Accordingly, potential environmental costs associated with the wind down of Avondale are not included in our $2 million accrual for environmental remediation costs or our $287 million estimate of Avondale asset write-downs and restructuring costs, or otherwise reflected in our consolidated financial statements. We expect that a significant

8


portion of any future environmental remediation costs we might incur at Avondale would be recoverable in accordance with government accounting practices under the Federal Acquisition Regulation ("FAR").
 
We believe that we are in material compliance with applicable environmental laws and regulations, and historical environmental compliance costs have not been material to our business. We could be affected by new environmental laws or regulations, including any enacted in response to concerns over climate change, other aspects of the environment, or natural resources. We have made the investments we believe are necessary to comply with environmental laws. We expect, however, to incur capital and operating costs in the future to comply with current and future environmental laws and regulations. At this time, we do not believe such costs will have a material effect on our financial position, results of operations, or cash flows.
 
With regard to occupational health and safety, the shipbuilding and ship repair industry involves work with hazardous materials and processes and remains one of the most hazardous industry segments. According to the Bureau of Labor Statistics, the shipbuilding and ship repair industry (NAICS 336611) ranks among the highest in several injury metrics. We have experienced one industrial related fatality in the past seven years. We strive to keep our Occupational Safety & Health Administration ("OSHA") compliance programs strong. In 1995, our Newport News shipyard became the first shipyard to be awarded the Star Award from OSHA's Voluntary Protection Program ("OSHA VPP"). To earn this award, we joined efforts with our unions and supported participation in the OSHA VPP, in which all parties assist each other to make our shipyard a safer place to work. Our CMSD facility and SN3's Grand Junction site have also been certified as OSHA VPP Star Sites.
 
The U.S. Navy, Nuclear Regulatory Commission, and DoE each regulate and control various matters relating to nuclear materials we handle. Subject to certain requirements and limitations, our contracts with the U.S. Navy and DoE generally provide for indemnity by the U.S. Government for losses resulting from our nuclear operations. For our commercial nuclear operations, we rely primarily on insurance carried by nuclear facility operators for risk mitigation, and we maintain limited insurance coverage for losses in excess of the coverage of facility operators.

Employees

We have approximately 36,000 employees. We are the largest industrial employer in Virginia and the largest private employer in Mississippi. We employ individuals specializing in 19 crafts and trades, with approximately 4,700 engineers and designers and approximately 2,300 employees with advanced degrees. Our workforce contains many third-, fourth- and fifth-generation employees, and approximately 1,100 employees have 40 or more years of continuous service. Employees in our shipbuilding divisions with more than 40 years of service achieve the honor of “Master Shipbuilder”.  As of December 31, 2015, there were 802 Master Shipbuilders at Newport News and 289 at Ingalls. We employ more than 5,000 veterans across the enterprise.

More than 1,400 apprentices are trained by our two shipbuilding units each year in more than 26 crafts and advanced programs. From nuclear pipe welders to senior executives, approximately 4,500 apprentice alumni, 3,000 at Newport News and 1,500 at Ingalls, continue to work with us.

Approximately 50% of our employees are covered by a total of eight collective bargaining agreements and two DoE site stabilization agreements. Newport News has three collective bargaining agreements covering represented employees, which expire in July 2017, August 2018, and December 2018. Newport News craft workers employed at the Kesselring Site near Saratoga Springs, New York are represented under an indefinite DoE site agreement. Newport News will begin negotiations in early 2016 with the International Association of Machinist and Aerospace Workers ("IAM"), which was recently determined to be the exclusive representative for approximately 200 Newport News radiological control, calibration, and laboratory technicians. Ingalls has five collective bargaining agreements covering represented employees, all of which expire in March 2018.  Approximately 35 SN3 craft employees at the Hanford Site near Richland, Washington are represented under an indefinite DoE site stabilization agreement. We believe that our relationship with our employees is satisfactory.

Item 1A. Risk Factors

An investment in our common stock or debt securities involves risks and uncertainties. We seek to identify, manage, and mitigate risks to our business, but risk and uncertainty cannot be eliminated or necessarily predicted. You should consider the following factors carefully, in addition to the other information contained in this Annual Report on Form 10-K, before deciding to purchase our securities.

Risks Related to Our Business
 
We depend heavily on a single customer, the U.S. Government, for substantially all of our business, and changes affecting this customer's priorities and spending could have a material adverse effect on our financial position, results of operations, or cash flows.

Our business consists primarily of the design, construction, repair, and maintenance of nuclear-powered ships, such as aircraft carriers and submarines, and non-nuclear ships, such as surface combatants and expeditionary warfare and amphibious assault ships, for the U.S. Navy and coastal defense surface ships for the U.S. Coast Guard, as well as the refueling and overhaul and inactivation of nuclear-powered ships for the U.S. Navy. Most of our revenues in 2015 were derived from products and services ultimately sold to the U.S. Government, and we expect this to continue in the foreseeable future. In addition, most of our backlog was U.S. Government related as of December 31, 2015. Our U.S. Government contracts are subject to various risks, including our customers' political and budgetary constraints and processes, changes in customers' short-range and long-range strategic plans, the timing of contract awards, significant changes in contract scheduling, intense contract and funding competition, difficulty in forecasting costs and schedules for bids on developmental and sophisticated technical work, delays in the timing of contract approval, and contractor suspension or debarment in the event of certain violations of legal or regulatory requirements. Any of these factors could affect our ability to do business with the U.S. Government, which would have a material adverse effect on our financial position, results of operations or cash flows.

Significant delays or reductions in appropriations for our programs, changes in customer priorities, and potential contract terminations could have a material adverse effect on our financial position, results of operations, or cash flows.

We are directly dependent upon congressional allocation of defense funds to the U.S. Navy and the U.S. Coast Guard. The funding of U.S. Government programs is subject to congressional budget authorization and appropriation processes. For certain programs, Congress appropriates funds on a fiscal year basis even though a program may be performed over several fiscal years. Consequently, programs are often partially funded initially and receive additional funding only as Congress makes additional appropriations. If we incur costs in excess of existing funding on a contract, we may be at risk for reimbursement of those costs unless and until additional funds are appropriated. We cannot predict the extent to which total funding or funding for individual programs will be included, increased, or reduced as part of the annual budget process, in continuing resolutions, or in individual supplemental appropriations.

The impact of Congressional actions to reduce the federal debt and resulting pressures on federal spending could adversely affect the total funding of individual ships or funding for individual programs and delay purchasing or payment decisions by our customers. In August 2011, the Budget Control Act (the "BCA") reduced the DoD top-line budget by $487 billion from fiscal years 2012 through 2021, representing approximately 8% of planned defense spending. Additionally, because Congress did not identify savings to reduce the U.S. deficit by up to $1.2 trillion prior to March 1, 2013, budgetary sequestration was implemented under the BCA. Sequestration requires an additional reduction from fiscal years 2012 through 2021 of $500 billion for defense spending, representing approximately 9% of planned defense spending, and $500 billion for non-defense discretionary spending, including the U.S. Coast Guard.

On December 26, 2013, the President signed into law the Bipartisan Budget Act of 2013 (the "BBA 2013"), which provided $63 billion in sequestration relief over two years, split evenly between defense and non-defense programs, and set overall discretionary spending at $1.012 trillion and $1.013 trillion for fiscal years 2014 and 2015, respectively. On November 2, 2015, the President signed into law the Bipartisan Budget Act of 2015 (the "BBA 2015"), which provided $80 billion in sequestration relief over two years, split evenly between defense and non-defense programs. The BBA 2015 provided sequestration relief of $50 billion and $30 billion for fiscal years 2016 and 2017, respectively, resulting in overall discretionary spending caps of $1.067 trillion and $1.070 trillion for fiscal years 2016 and 2017, respectively. Sequestration remains in effect under the BCA for fiscal years 2018 through

11


2021. Enactment of the BBA 2015 enabled the House and Senate Appropriations Committees to agree upon final appropriations levels and enabled final passage and enactment of the Consolidated Appropriations Act of 2016, which provided general spending for most of the U.S. federal government, including the DoD, DoE, and the Department of Homeland Security.

The Consolidated Appropriations Act of 2016 specifically provided funding for construction of CVN-79 John F. Kennedy, advance procurement funding for CVN-80 Enterprise, construction of two SSN-774 Virginia-class submarines, procurement for the CVN-73 USS George Washington RCOH, advance procurement for the CVN-74 USS John C. Stennis RCOH, continuation of DDG-51 Arleigh Burke-class destroyer production, advance procurement for LHA-8 (unnamed), procurement of an additional LPD-17 San Antonio-class warship, advance procurement to accelerate the LXR program, research, development, test, and evaluation (“RDT&E”) funding for the Ohio replacement program, procurement of a T-AO(X) fleet oiler, and procurement of an additional NSC for the U.S. Coast Guard.

While the BBA 2015 eliminated the implementation of sequestration reductions for fiscal years 2016 and 2017, uncertainty continues regarding the specific effects of sequestration in fiscal years 2018 through 2021, and related funding reductions that could result in the cancellation of or decreased funding for our existing programs and/or a lack of funding for future programs.

The impact of the continuing federal fiscal debates for fiscal year 2017 and beyond remains uncertain, and we cannot predict the impact that the sequestration cuts or other defense spending cuts may have on funding for our individual programs. Long-term funding for certain programs in which we participate may be reduced, delayed, or canceled. In addition, defense spending cuts and delays could adversely affect the viability of our suppliers and subcontractors and employee base. Our contracts or subcontracts under programs in which we participate may be terminated or adjusted by the U.S. Government or the prime contractor as a result of lack of government funding or reductions or delays in government funding. Significant reductions in the number of ships procured by the U.S. Navy or significant delays in funding our ship programs would have a material adverse effect on our financial position, results of operations, or cash flows.

The budget environment, including sequestration as currently mandated, remains a significant long-term risk. Considerable uncertainty exists regarding how future budget and program decisions will develop and what challenges budget reductions will present for the defense industry. We believe continued budget pressures will have serious negative consequences for the security of our country, the defense industrial base, including us, and the customers, employees, suppliers, subcontractors, investors, and communities that rely on companies in the defense industrial base. Although it is difficult to determine specific impacts, we expect that over the longer term, the budget environment may result in fewer contract awards and lower revenues, profits, and cash flows from our U.S. Government contracts. Congress continues to discuss various options to address sequestration in future budget planning, but we cannot predict the outcome of these efforts. It is likely budget and program decisions made in this environment will have long-term impacts on us and the entire defense industry.

Demand for our products and services can also be affected by potential changes in customer priorities due to changes in military strategy and planning. In response to the need for cheaper alternatives and the proliferation of "smart weapons," future strategy reassessments by the DoD may result in decreased demand for our shipbuilding programs, including our aircraft carrier programs. For the year ended December 31, 2015, our aircraft carrier programs accounted for approximately 35% of our consolidated revenue. We cannot predict the impact of changes in customer priorities on existing, follow-on, replacement, or future programs. A shift of priorities to programs in which we do not participate and related reductions in funding for or the termination of programs in which we do participate could have a material adverse effect on our financial position, results of operations, or cash flows.
 
The U.S. Government generally has the ability to terminate contracts, in whole or in part, with little to no prior notice, for convenience or for default based on performance. In the event of termination for the U.S. Government's convenience, contractors are normally protected by provisions covering reimbursement of costs already incurred on the contracts and profit on those costs up to the amount authorized under the contract, but not the anticipated profit that would have been earned had the contract been completed. Such a termination could also result in the cancellation of future work on the related program. Termination resulting from our default can expose us to various liabilities, including excess re-procurement costs, and could negatively affect our ability to compete for future contracts. Any contract termination could have a material adverse effect on our financial condition, results of operations, or cash flows.


12


Cost growth on fixed price and other contracts that cannot be justified as increases in contract value due from customers exposes us to reduced profitability and to 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. Cost growth can occur if expenses to complete a contract increase due to technical challenges, manufacturing difficulties, delays, workforce-related issues, or inaccurate initial estimates used for calculating contract costs. Reasons may include unavailability or reduced productivity of labor, the nature and complexity of the work performed, the timeliness and availability of materials, major subcontractor performance or product quality issues, performance delays, availability and timing of funding from the customer, and natural disasters. The process of estimating contract costs requires significant judgment and expertise. A significant increase in contract costs from our original cost estimates on one or more programs could have a material adverse effect on our financial position, results of operations, or cash flows.
 
Our ability to recover the costs we incur and realize profits on contracts with our U.S. Government customers depends on the type of contract under which we are performing. Our U.S. Government business is currently performed under firm fixed price ("FFP"), fixed price incentive ("FPI"), cost plus incentive fee ("CPIF"), cost plus fixed fee ("CPFF"), and cost plus award fee ("CPAF") contracts. Under FFP contracts, we retain all cost savings on completed contracts but are responsible for the full amount of all expenditures in excess of the contract price. FPI contracts, on the other hand, are flexibly priced agreements under which cost overruns and underruns to an agreed target cost are shared between the U.S. Government and us. The U.S. Government is liable for its share of allowable costs up to a ceiling price, and we are responsible for all costs incurred in excess of such ceiling price, typically 125-135% of target cost. Our profit on FPI contracts varies according to a formula set forth in the contract that generally compares the amount of costs incurred to the contract target cost. Under CPIF, CPFF and CPAF contracts, we are generally required to perform the contract only to the extent the U.S. Government makes funds available, and we recover all allowable costs incurred in the performance of the contract. Under CPIF contracts, our profit is determined by a contractually specified formula that compares allowable incurred costs to the contract target cost, subject in some instances to a maximum or minimum fee percentage. Under CPFF contracts, the dollar amount of profit received is the same without regard to the amount of costs incurred. Under CPAF contracts, the dollar amount of profit received is determined by the award fee provisions in the contract.

Of Ingalls' revenues in 2015, approximately 89% were generated from FPI contracts, approximately 4% were generated from FFP contracts, approximately 4% were generated from CPFF contracts, and approximately 3% were generated from CPAF contracts. Of Newport News' 2015 revenues, approximately 33% were generated from FPI contracts, consisting primarily of submarine construction contracts, approximately 32% were generated from CPFF contracts, approximately 31% were generated from CPIF contracts, consisting primarily of aircraft carrier construction and RCOH contracts, approximately 3% were generated from FFP contracts, and approximately 1% were generated from CPAF contracts. Substantially all of our Other segment's 2015 revenues were generated from FFP contracts. To the extent our mix of contract types change in the future, our ability to recover our costs and realize profits on our contracts can be negatively affected.
 
Our earnings and profitability depend upon our ability to perform under contracts.
 
When agreeing to contract terms, we make assumptions and projections about future conditions and events, many of which extend over long periods. Our assumptions and projections are based upon our assessments of the productivity and availability of labor, the complexity of the work to be performed, the cost and availability of materials, the impact of delayed performance, and the timing of product deliveries. We may experience significant variances from our assumptions and projections, delays in our contract performance, and variances in the timing of our product deliveries. If our actual experience differs significantly from one or more of our assumptions or projections, or, if we incur unanticipated contract costs, the profitability of the related contracts may be adversely affected.

Our earnings and profitability depend, in part, upon subcontractor performance and raw material and component availability and pricing.
 
We rely on other companies to provide raw materials, major components, and sub-systems for our products, and we rely on subcontractors to produce hardware elements and sub-assemblies and perform certain services that we provide to our customers. We are subject to potential delivery disruptions and performance problems caused by our suppliers and subcontractors. Our ability to perform our obligations as a prime contractor could be adversely

13


affected if one or more of our suppliers 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 to manufacture our products can increase over the terms of our contracts. We may be protected from increases in material costs through cost escalation provisions contained in some of our U.S. Government contracts, to the extent that such increases are consistent with industry indices. Even with these provisions, however, the difference in basis between our actual material costs and these indices may expose us to cost uncertainty. In addition, significant delays in deliveries of key raw materials, which may occur as a result of availability or price, could have a material adverse effect on our financial position, results of operations, or cash flows.
 
In connection with our U.S. Government contracts, we are required to procure certain raw materials, components and parts from supply sources approved by the U.S. Government. As a result of consolidation in the defense industry, only one supplier may exist for certain components and parts required to manufacture our products. The inability of a sole source supplier to provide a necessary component in a timely or cost-effective manner could have a material adverse effect on our financial position, results of operations, or cash flows.

Changes to Department of Defense business practices could have a material effect on DoD's procurement process and adversely impact our current programs and potential new awards.

The defense industry has implemented, and we expect will continue to implement, significant changes to business practices resulting from, among other causes, an increased focus by DoD on affordability, efficiencies, recovery of costs, and a reprioritization of available defense funds to key areas for future defense spending. The DoD continues to adjust its procurement practices, requirements criteria, and source selection methodology in an ongoing effort to reduce costs, gain efficiencies and enhance program management and control. In addition, the DCMA and DCAA have implemented cost recovery/cost savings initiatives to prioritize efforts to recover costs. As a result of certain of these initiatives, we have experienced and may continue to experience a higher number of audits and/or lengthened periods of time required to close open audits. In addition, the thresholds for certain allowable costs, including compensation costs, have been significantly reduced, and other thresholds are being challenged, debated, and, in certain cases, modified. Significant changes to the thresholds for allowable costs could adversely affect our financial position, results of operations or cash flows.

In September 2014, the DoD initiated Better Buying Power 3.0 ("BBP 3.0") to address its growing concern that the United States' technological superiority over potential adversaries is being threatened. BBP 3.0 includes eight focus areas: achieve affordable programs; achieve dominant capabilities while controlling life cycle costs; incentivize productivity in industry and government; incentivize innovation in industry and government; eliminate unproductive processes and bureaucracy; promote effective competition; improve tradecraft in acquisition of services; and improve the professionalism of the total acquisition workforce. While some of the larger objectives remained the same as those in Better Buying Power 2.0, their focus has narrowed and the circle of stakeholders has expanded.

We expect DoD's focus on business practices to impact the contracting environment in which we operate as we and others in the industry adjust our practices to address the new initiatives and the reduced level of spending by the DoD. We are assessing internally how we can respond to and support these changes, including how we can further reduce costs and increase productivity, modify how we respond to acquisition proposals, and revise our areas of focus. Depending on how these initiatives are implemented, they could have an impact on our current programs, as well as new business opportunities with the DoD.
 
Our future success depends, in part, on our ability to deliver our products and services at an affordable life cycle cost, requiring us to develop and maintain technologies, facilities, equipment and a qualified workforce to meet the needs of current and future customers.
 
Shipbuilding is a long cycle business, and our success depends on quality, cost, and schedule performance on our contracts. We must develop and maintain the workforce, technologies, facilities, equipment, and financial capacity needed to deliver our products and services at an affordable life cycle cost. If we fail to maintain our competitive position in these areas, we could lose future contracts to our competitors, which could have a material adverse effect on our financial position, results of operations or cash flows.


14


Our operating results are heavily dependent upon our ability to attract and retain at competitive costs a sufficient number of engineers and workers with the necessary skills and/or security clearances. At the same time, stable future revenues and costs are important for us to maintain a qualified workforce. Development and maintenance of the necessary nuclear expertise and the challenges of hiring and training a qualified workforce can be a limitation on our business. If qualified personnel become scarce, we could experience higher labor, recruiting, or training costs to attract and retain qualified employees, or, if we fail to attract and retain qualified personnel, we could incur difficulties in performing our contracts and attracting new contract awards.
 
Competition within our markets or an increase in bid protests may reduce our revenues and market share.
 
U.S. defense spending levels are uncertain and difficult to predict. The reduction in shipbuilding activity by the U.S. Navy, as evidenced by the reduction in fleet size from 566 ships in 1989 to 272 ships as of December 31, 2015, has resulted in workforce reductions in the industry but little infrastructure consolidation. The general result has been fewer contracts awarded to the same fixed number of shipyards. Six major private United States shipyards, three of which we own, plus numerous other smaller private shipyards compete for contracts to construct, overhaul, repair, and convert naval vessels. Additionally, our products, such as aircraft carriers, submarines, amphibious assault ships, surface combatants, and other ships, compete for funding with each other, as well as with other defense products and services. We expect competition for future shipbuilding programs to be intense.

We compete with another large defense contractor for construction contracts to build surface combatants and submarines, and we are currently engaged in a competition to build either the next amphibious assault ship (LHA-8) or six fleet oilers (T-AO(X)). We may in the future compete with the same and other defense contractors to build other ships for which we are currently the sole source, including expeditionary warfare and amphibious assault ships. Moreover, reductions in U.S. defense spending that reduce the demand for the types of ships we build and services we provide increase our risk exposure to market competition. If we are unable to continue to compete successfully against our current or future competitors, we may experience declines in revenues and market share, which could negatively impact our financial condition, results of operations, or cash flows.

Although we are the only company currently capable of refueling nuclear-powered aircraft carriers, two existing U.S. Government-owned shipyards may be able to refuel nuclear-powered aircraft carriers if substantial investments in facilities, personnel, and training were made. U.S. Government-owned shipyards engage in the refueling, overhaul, and inactivation of SSN-688 Los Angeles-class submarines and are capable of repairing and overhauling non-nuclear ships. The 2012 National Defense Authorization Act required DoD to develop a core depot level maintenance capability to refuel nuclear aircraft carriers. The 2013 Defense Authorization Act, however, modified the 2012 Act by restoring an exception for the nuclear refueling of an aircraft carrier from the definition of core depot level maintenance. The 2013 Act also amended and clarified the exception to cover the concurrent refueling and overhaul of an aircraft carrier, as well as the defueling of an aircraft carrier. Similarly, the 2013 Act restored an exclusion for nuclear aircraft carrier programs from the definition of core logistics capabilities that was contained in previous law. If a U.S. Government-owned shipyard were to become capable and engaged in the refueling of nuclear-powered aircraft carriers, our financial position, results of operations, or cash flows could be adversely affected.
 
We also compete in the shipbuilding engineering, planning, and design market with other companies that provide engineering support services. Such competition increases the risk that we may not be the successful bidder on future U.S. Navy engineering proposals, including aircraft carrier research and development, submarine design, and surface combatant and amphibious assault ship program contracts.
 
Our competitive environment is also affected by bid protests from unsuccessful bidders on new program awards. As the competitive environment intensifies, the number of bid protests may increase. Bid protests can result in an award decision being overturned, requiring a re-bid of the contract. Even when a bid protest does not result in a re-bid, resolution of the matter typically extends the time until contract performance can begin, which may reduce our earnings in the period in which the contract would otherwise be performed.

As a U.S. Government contractor, we are heavily regulated and could be adversely affected by changes in regulations or negative findings from a U.S. Government audit or investigation.
 
As a U.S. Government contractor, we must comply with significant regulatory requirements, including those relating to procurement, cyber security, and nuclear operations. Government contracting requirements increase our contract

performance and compliance costs and change on a consistent basis. In addition, our nuclear operations are subject to an enhanced regulatory environment, which results in increased performance and compliance efforts and costs. New laws, regulations, or procurement requirements, or changes to existing ones (including, for example, regulations related to allowability of compensation costs, cyber security, counterfeit parts, specialty metals, and conflict minerals), can increase our performance and compliance costs and reduce our profitability.
 
We operate in a heavily regulated environment and are routinely audited and reviewed by the U.S. Government and its various agencies, including the U.S. Navy's Supervisor of Shipbuilding, the DCAA, and the DCMA. These agencies review our contract performance, cost structures, and compliance with applicable laws, regulations, and standards, as well as the adequacy of, and our compliance with, our internal control systems and internal policies. Systems subject to audit or review include our accounting systems, purchasing systems, billing systems, property management and control systems, cost estimating systems, earned value management systems, compensation systems, and management information and cyber security systems. If an audit uncovers improper or illegal activities, we may be subject to administrative, civil, or criminal proceedings, which could result in fines, penalties, repayments, or compensatory, treble, or other damages. Certain U.S. Government findings against a contractor can also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. Allegations of impropriety can also cause us significant reputational harm.

Whether or not illegal activities are alleged, the U.S. Government has the ability to decrease or withhold contract payments if it determines significant deficiencies exist in business systems subject to its review. The U.S. Government has, in certain instances, withheld payments on certain of our contracts upon its assessment that deficiencies exist with one or more of our business systems. When appropriate, we will modify our affected business systems to address the U.S. Government's concerns.
 
The U.S. Government has, from time to time, recommended that certain of our contract prices be reduced, or that certain costs allocated to our contracts be disallowed. These recommendations sometimes involve substantial dollar amounts. In response to U.S. Government audits, investigations, and inquiries, we have also in the past made adjustments to our contract prices and the costs allocated to our government contracts. Such audits, investigations, and inquiries may result in future reductions of our contract prices. Any costs we incur that are determined to be unallowable or improperly allocated to a specific contract will not be reimbursed or must be refunded if previously reimbursed.
 
We must comply with a variety of federal laws and regulations, including the FAR, the Truth in Negotiations Act, the False Claims Act, the Procurement Integrity Act, the International Traffic in Arms Regulations promulgated under the Arms Export Control Act, the Close the Contractor Fraud Loophole Act, the Foreign Corrupt Practices Act, and Cost Accounting Standards, and we are subject, from time to time, to U.S. Government investigations relating to our operations. If we are convicted or otherwise found to have engaged in illegal activities, or are found not to have acted responsibly as defined by the law, we may be subject to reductions in the values of contracts, contract modifications or terminations, penalties, fines, repayments, compensatory, treble, or other damages, or suspension or debarment, any of which could have a material adverse effect on our financial position, results of operations, or cash flows.
 
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, and failure to meet these obligations could adversely affect our profitability and future prospects.
 
We design, develop, and manufacture products and provide services applied by our customers in a variety of environments. Problems and delays in product development or with delivery of subcontractor components or services as a result of issues with respect to design, technology, licensing and intellectual property rights, labor, learning curve assumptions, or materials and parts could prevent us from satisfying contractual requirements.
 
First-in-class ships, also known as lead ships, usually have new technology that is supplied by the U.S. Navy, other contractors, or us. Problems in developing these new technologies or design changes in the construction process can lead to delays in the design schedule needed for construction. The risks associated with new technology or mid-construction design changes can both increase the cost of a ship and delay delivery. Late delivery of information can also cause inefficiencies in the construction process, increase costs, and put the delivery schedule at risk, which could adversely affect our profitability and future prospects.
 

16


Our products cannot always be tested and proven and are otherwise subject to unforeseen problems, including premature failure of products that cannot be accessed for repair or replacement, substandard quality or workmanship, and unplanned degradation of product performance. These failures could result in loss of life or property and could negatively affect our results of operations by causing unanticipated expenses not covered by insurance or indemnification from the customer, diversion of management focus to respond to unforeseen problems, loss of follow-on work, and, in the case of certain contracts, repayment to the government customer of contract costs and fee payments previously received.
 
We have experienced quality issues in the past with respect to products and services that we sell to our U.S. Government customers. These issues have required significant resources to analyze the source of the deficiencies and implement corrective actions. We may discover quality issues in the future related to our products and services that require analysis and corrective action. Such issues and our responses and corrective actions could have a material adverse effect on our financial position, results of operations, or cash flows.
 
We may not recover all of our costs related to the wind down of shipbuilding at our Avondale shipyard.
 
In October 2014, we ceased shipbuilding construction operations at our Avondale, Louisiana shipyard and consolidated all Ingalls shipbuilding into our Pascagoula shipyard. In connection with and as a result of the wind down of shipbuilding at Avondale, we have incurred substantial restructuring costs and asset write-downs, which we currently estimate at $287 million. We believe that substantially all such expenses are recoverable under existing flexibly-priced contracts or future negotiated contracts in accordance with FAR provisions governing the treatment of restructuring and shutdown related costs.

We have engaged in communications and negotiations with the U.S. Navy since 2010 regarding the amount and recovery of our restructuring and shutdown costs. In August 2015, we received a letter from the Supervisor of Shipbuilding's Contracting Officer ("Contracting Officer"), with a preliminary determination that our method of allocating as indirect costs certain employee retention and incentive expenses, which could be up to $57 million, did not comply with cost accounting allocation regulations. We have responded with our basis supporting our cost allocation positions and sought a determination that supports our method of cost allocation.

We currently do not have an agreement with the U.S. Navy regarding the government contract accounting and pricing treatment of the restructuring and shutdown costs associated with our wind down of operations at Avondale. We may also incur environmental costs in connection with the wind down. Such costs, which we cannot reasonably estimate at this time, could be significant. The actual restructuring expenses we incur in connection with our wind down of Avondale, including potential environmental costs, may be greater than our current estimate, and any inability to recover our restructuring expenses substantially in accordance with our cost recovery expectations could result in a material adverse effect on our financial position, results of operations, or cash flows.

We use estimates when accounting for contracts. Changes in estimates could affect our profitability and our overall financial position.
 
Contract accounting requires judgment relative to assessing risks, estimating contract revenues and costs, and making assumptions for schedule and technical issues. The size and nature of many of our contracts make the estimation of total revenues and costs at completion complicated and subject to many variables. For new shipbuilding programs, we estimate, negotiate and contract for construction of ships that are not completely designed. Assessing risks, estimating contract revenues and costs, and making assumptions for schedule and technical issues for these ships are subject to the variability of the final ship design and evolving scope of work. Our assumptions on ship contracts include the length of time to complete the contract, because total costs include expected increases in wages and material prices. Similarly, our assumptions include the future impact of our efficiency initiatives and cost reduction efforts. We consider incentives, awards, and penalties related to contract performance in estimating revenues and profit rates, and we record them when sufficient information exists to assess anticipated contract performance.

The judgment and estimation processes described above are significant to our contract accounting, and materially different amounts can be generated if different assumptions are used or if actual events differ from our assumptions. Future changes in underlying assumptions, circumstances, or estimates may have a material adverse effect on our future financial position, results of operations, or cash flows. See Critical Accounting Policies, Estimates, and Judgments in Item 7.

Our business is subject to disruption caused by natural disasters, environmental disasters, and other events that could have a material adverse effect on our financial position, results of operations, or cash flows.
 
We have significant operations located in regions of the United States that have been and may in the future be exposed to damaging storms, such as hurricanes, floods, and environmental disasters, such as oil spills. The damage and disruption resulting from natural and environmental disasters may be significant. Natural disasters can disrupt our facilities, systems, or projects, which can interrupt operational processes and performance on our contracts. Should insurance or other risk transfer mechanisms be unavailable or insufficient to recover material costs associated with natural or environmental disasters, we could experience a material adverse effect on our financial position, results of operations, or cash flows. See Our insurance coverage may be inadequate to cover all of our significant risks or our insurers may deny coverage of material losses we incur, which could adversely affect our profitability and financial position.
 
Natural disasters can disrupt our workforce, electrical and other power distribution networks, computer and internet operations and accessibility, and the critical industrial infrastructure needed for normal business operations. These disruptions could adversely affect our contract performance and financial results. Environmental disasters, particularly oil spills in waterways and bodies of water used for the transport and testing of our ships, can disrupt the timing of performance under our contracts with the U.S. Navy and the U.S. Coast Guard.

Our suppliers and subcontractors are also subject to natural and environmental disasters that could affect their ability to deliver products or services or otherwise perform their contracts. Performance failures by our subcontractors due to natural or environmental disasters may adversely affect our ability to perform our contracts, which could reduce our profitability in the event damages or other costs are not recoverable from the subcontractor, the customer, or insurers. Such events could also result in a termination of the prime contract and have an adverse effect on our ability to compete for future contracts.

In addition to the types of events described above, operation of our facilities may be disrupted by civil unrest, acts of sabotage or terrorism, and other local security concerns. Such events may require us to incur greater costs for security or to shut down operations for a period of time.
 
Our insurance coverage may be inadequate to cover all of our significant risks or our insurers may deny coverage of material losses we incur, which could adversely affect our profitability and financial position.
 
We seek to negotiate and enter into insurance agreements to cover our significant risks and potential liabilities, including, among others, natural disasters, product liability, and business interruption resulting from an insured property loss. In some circumstances, we may be indemnified for losses by the U.S. Government, subject to the availability of appropriated funds. Not every risk or liability can be protected by insurance, and, for insurable risks, the limits of coverage reasonably obtainable in the market may not be sufficient to cover the full amount of actual losses or liabilities incurred, including, for example, in the case of a catastrophic hurricane. In addition, the nature of our business makes it difficult to quantify the disruptive impact of such events. Such limitations on the availability of insurance coverage may result in us bearing substantial costs for uninsured losses, which could have a material adverse effect on our financial position, results of operations, or cash flows. Even in cases where we have insurance coverage, disputes with insurance carriers over coverage may affect the timing of cash flows, and, if litigation with the insurance carrier becomes necessary, an outcome unfavorable to us may have a material adverse effect on our financial position, results of operations, or cash flows.
 
Our business could suffer if we are unsuccessful in negotiating new collective bargaining agreements.
 
Approximately 50% of our employees are covered by a total of eight collective bargaining agreements and two DoE site stabilization agreements. Newport News has three collective bargaining agreements covering represented employees, which expire in July 2017, August 2018, and December 2018. Newport News craft workers employed at the Kesselring Site near Saratoga Springs, New York are represented under an indefinite DoE site agreement. Newport News will begin negotiations in early 2016 with IAM, which was recently determined to be the exclusive representative for approximately 200 Newport News radiological control, calibration, and laboratory technicians. Ingalls has five collective bargaining agreements covering represented employees, all of which expire in March 2018.  Approximately 35 SN3 craft employees at the Hanford Site near Richland, Washington are represented under an indefinite DoE site stabilization agreement.


18


Collective bargaining agreements generally expire after three to five years, and we negotiate successor agreements as each of our collective bargaining agreements expires. While we believe we maintain good relationships with our represented workers, it is possible that we may experience difficulties renegotiating expiring collective bargaining agreements. We have, in the past, experienced work stoppages, strikes, and other labor disruptions associated with the collective bargaining of new labor agreements. If we experience such events in the future, we could incur additional expenses or work delays that could adversely affect programs served by employees who are covered by collective bargaining agreements.
 
Changes in key estimates and assumptions, such as discount rates and assumed long-term returns on assets, actual investment returns on our pension plan assets, and legislative and regulatory actions could significantly affect our earnings, equity, and contributions to our defined benefit pension and other postretirement benefit plans in future periods.
 
Our pension and retiree health care costs are dependent on significant judgment regarding various estimates and assumptions, particularly with respect to the discount rate and expected long-term rates of return on plan assets. Changes to these estimates and assumptions could have a material adverse effect on our financial position, results of operations, or cash flows. Differences between actual investment returns and our assumed long-term returns on assets will result in future changes in pension expense and the funded status of our plans, and could increase future funding of the plans.

Timing differences exist among the accrual of pension costs under accounting principles generally accepted in the United States of America ("GAAP"), pension funding requirements, and the recovery of pension costs that are allowable under our government contracts. Such timing differences could have a material adverse effect on our financial position, results of operations, or cash flows. On December 27, 2011, the U.S. Cost Accounting Standards ("CAS") Board issued its final CAS Harmonization Rule. The rule impacted pension costs on contracts beginning in 2013 and was effective for forward pricing purposes for contracts negotiated on or after February 27, 2012. Although we believe contractors are entitled to an equitable adjustment on CAS-covered contracts awarded prior to the February 27, 2012 effective date, the application of this rule could have a material adverse effect on our financial position, results of operations, or cash flows if we are unable to successfully recover such equitable adjustment.

For a complete discussion regarding how our consolidated financial statements can be affected by pension plan accounting policies and regulatory changes, see Critical Accounting Policies, Estimates, and Judgments in Item 7.
 
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 existing federal, state, and local environmental protection laws and regulations. In addition, we could be affected by future laws or regulations, including those imposed in response to concerns over climate change, other aspects of the environment, or natural resources. We expect to incur future capital and operating costs to comply with current and future environmental laws and regulations, and such costs could be substantial, depending on the future proliferation of environmental rules and regulations and the extent to which we discover currently unknown environmental conditions.
 
Shipbuilding operations require the use of hazardous materials. Our shipyards also generate significant quantities of wastewater, which we treat before discharging pursuant to various permits. To handle these materials, our shipyards have an extensive network of aboveground and underground storage tanks, some of which have leaked and required remediation in the past. In addition, our handling of hazardous materials has sometimes resulted in spills in our shipyards and occasionally in adjacent rivers and waterways in which we operate. Our shipyards maintain extensive waste handling programs that we periodically modify, consistent with changes in applicable laws and regulations. See Environmental, Health and Safety in Item 1.
 
Various federal, state, and local environmental laws and regulations impose restrictions on the discharge of pollutants into the environment and establish standards for the transportation, storage, and disposal of toxic and hazardous wastes. Substantial fines, penalties, and criminal sanctions may be imposed for noncompliance, and certain environmental laws impose joint and several "strict liability" for remediation of spills and releases of oil and hazardous substances. Such laws and regulations render a party liable for environmental cleanup and remediation costs and damage without regard to negligence or fault on the part of such party and could expose us to liability for the conduct of or conditions caused by third parties.

19


 
In addition to fines, penalties, and criminal sanctions, environmental laws and regulations may require the installation of costly pollution control equipment or operational changes to limit pollution emissions or discharges and/or to decrease the likelihood of accidental hazardous material releases. We have incurred, and expect to incur in the future, costs to comply with federal and state environmental laws and regulations related to the cleanup of pollutants released into the environment. In addition, if we are found to be in violation of the 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, which would continue until the EPA concluded that the cause of the violation was cured. Facilities on the "Excluded Parties List" are prohibited from working on any U.S. Government contract.
 
The adoption of new environmental 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, our inability to recover related costs under our government contracts, or the financial insolvency of other responsible parties could cause us to incur costs that could have a material adverse effect on our financial position, results of operations, or cash flows.

We ceased shipbuilding construction at our Avondale, Louisiana shipyard in 2014. Our wind down of operations at this shipyard may result in environmental costs, the amount of which we cannot currently estimate. Such costs could be significant and could have a material adverse effect on our financial position, results of operations, or cash flows.
 
Market volatility and adverse capital or credit market conditions may affect our ability to access cost-effective sources of funding and may expose us to risks associated with the financial viability of suppliers and subcontractors and the ability of counterparties to perform on financial agreements.
 
The financial markets can experience high levels of volatility and disruption, reducing the availability of credit for certain issuers. We may access these markets from time to time to support certain business activities, including funding acquisitions and capital expansion projects and refinancing existing indebtedness. We also access these markets to obtain credit support for our workers' compensation self-insurance program and arrange for letters of credit. A number of factors could cause us to incur increased borrowing costs and to have greater difficulty accessing public and private markets for debt. These factors include disruptions or declines in the global capital markets and/or a decline in our financial performance, outlook, or credit ratings. The occurrence of any or all of these events may adversely affect our ability to fund our operations, meet contractual or financing commitments, make future investments or desirable acquisitions, or respond to competitive challenges.
 
Tightening credit markets could also adversely affect our suppliers' and subcontractors' ability to obtain financing. Delays in suppliers' or subcontractors' ability to obtain financing, or the unavailability of financing, could negatively affect their ability to perform their contracts with us and cause our inability to perform our contracts. The inability of our suppliers and subcontractors to obtain financing could also result in the need for us to transition to alternate suppliers and subcontractors, which could result in significant incremental costs and delays.
 
We have existing agreements with counterparties in the financial markets, including brokers and dealers, commercial banks, and other institutional parties, and may in the future enter into agreements with such parties. These transactions expose us to potential credit risk in the event of default of a counterparty. In addition, our credit risk may be increased when collateral held by us to secure performance of a counterparty cannot be liquidated upon a sale or is liquidated at prices not sufficient to recover the full amount due to us under the related contract.
 
Our reputation and our ability to do business may be impacted by the improper conduct of employees, agents, or business partners.
 
Our compliance program includes detailed compliance plans and related compliance controls, policies, procedures, and training designed to prevent and detect misconduct by employees, agents, or business partners that would violate the laws of the jurisdictions in which we operate, including laws governing payments to government officials, the protection of export controlled or classified information, cost accounting and billing, competition, and data privacy. We may not, however, prevent all such misconduct committed by our employees, agents, or business partners, and the risk of improper conduct may be expected to increase as we expand into commercial markets and foreign jurisdictions. Any improper actions by our employees, agents, or business partners could subject us to administrative, civil, or criminal investigations and monetary and non-monetary penalties, including suspension or

20


debarment, which could have a material adverse effect on our financial position, results of operations, or cash flows. Any such improper actions could also cause us significant reputational harm.

Our business could be negatively impacted by security threats, including cyber security threats, and related disruptions.
 
As a defense contractor, we rely on our information technology infrastructure to process, transmit, and store electronic information, including classified and other sensitive information of the U.S. Government. While we maintain stringent information security policies and protocols, we face cyber security and other security threats to our information technology infrastructure, including threats to our and the U.S. Government's proprietary and classified information. We face unauthorized and unlawful attempts to gain access to our information technology infrastructure, including coordinated attacks from groups of hackers, and we could also face attempts to gain physical access to classified and other sensitive information located at our facilities. Our information technology infrastructure is critical to the efficient operation of our business and essential to our ability to perform day-to-day operations. Breaches of our information technology infrastructure or physical facilities could cause us to incur significant recovery and restoration expenses; degrade performance on existing contracts; and expose us to reputational damage, potential liability, or the loss of current or future contracts, including work on sensitive or classified systems for the U.S. Government, which could have a material adverse effect on our operations, financial position, results of operations, or cash flows.
 
Our nuclear operations subject us to various environmental, regulatory, financial, and other risks.
 
The design, construction, refueling and overhaul, repair, and inactivation of nuclear-powered aircraft carriers and nuclear-powered submarines, our nuclear facilities used to support such activities, our nuclear operations at DoE sites, and our activities in the commercial nuclear market subject us to various risks, including:

Potential liabilities relating to harmful effects on the environment and human health resulting from nuclear operations and the storage, handling, and disposal of radioactive materials, including nuclear assemblies and their components;
Unplanned expenditures relating to maintenance, operation, security, and repair, including repairs required by the U.S. Navy, the Nuclear Regulatory Commission or the DoE;
Reputational harm;
Potential liabilities arising out of a nuclear incident whether or not it is within our control; and
Regulatory noncompliance and loss of authorizations or indemnifications necessary for our operations.

Failure to properly handle nuclear materials could pose a health risk to humans or wildlife and could cause personal injury and property damage, including environmental contamination. If a nuclear accident were to occur, its severity could be significantly affected by the volume of the materials and the speed of corrective action taken by us and emergency response personnel, as well as other factors beyond our control, such as weather and wind conditions. Actions we might take in response to an accident could result in significant costs.

Our nuclear operations are subject to various safety related requirements imposed by the U.S. Navy, DoE, and Nuclear Regulatory Commission. In the event of noncompliance, these agencies may increase regulatory oversight, impose fines, or shut down our operations, depending on their assessment of the severity of the noncompliance. In addition, new or revised security and safety requirements imposed by the U.S. Navy, DoE, and Nuclear Regulatory Commission could necessitate substantial capital and other expenditures.

Subject to certain requirements and limitations, our contracts with the U.S. Navy and DoE generally provide for indemnity by the U.S. Government for costs arising out of or resulting from our nuclear operations. We may not, however, be indemnified for all liabilities we may incur in connection with our nuclear operations. To mitigate risks related to our commercial nuclear operations, we rely primarily on insurance carried by nuclear facility operators and our own limited insurance for losses in excess of the coverage of facility operators. Such insurance, however, may not be sufficient to cover our costs in the event of an accident or business interruption relating to our commercial nuclear operations, which could have a material adverse effect on our financial position, results of operations, or cash flows.
 

21


Changes in future business conditions could cause business investments, recorded goodwill, and/or purchased intangible assets to become impaired, resulting in substantial losses and write-downs that would reduce our operating income.
 
As part of our business strategy, we acquire non-controlling and controlling interests in businesses. We make acquisitions and investments following careful analysis and due diligence processes designed to achieve a desired return or strategic objective. Business acquisitions generally involve estimates, assumptions and judgments in determining acquisition prices, which prices are allocated among acquired assets, including goodwill, based upon fair market values. Notwithstanding our analyses, due diligence processes and business integration efforts, actual operating results of acquired businesses may vary significantly from initial estimates. In such events, we may be required to write down our carrying value of the related goodwill and/or purchased intangible assets. In addition, declines in the trading price of our common stock or the market as a whole can result in goodwill and/or purchased intangible asset impairment charges.

As of December 31, 2015, goodwill and purchased intangible assets generated from prior business acquisitions accounted for approximately 16% and 8%, respectively, of our total assets. We evaluate goodwill values for impairment annually on November 30, or when evidence of potential impairment exists. We also evaluate the values of purchased intangible assets when evidence of potential impairment exists. The impairment tests are based on several factors requiring judgment. As a general matter, a significant decrease in expected cash flows or changes in market conditions may indicate potential impairment of recorded goodwill or purchased intangible assets.

In the fourth quarter of 2015, the second quarter of 2015, and the fourth quarter of 2014, we recorded goodwill impairment charges at our Other segment of $16 million, $59 million, and $47 million, respectively. The Other segment, established in the second quarter of 2014 following the acquisition of UPI, is sensitive to developments in the oil and gas industry. The goodwill impairment charges were primarily driven by continuing declines in oil prices and the resulting decreases in industry market multiples. In the fourth quarter of 2015, we recorded an intangible asset impairment of $27 million at our Other segment as a result of declining market conditions and updated expectations.
 
Adverse equity market conditions that result in a decline in market multiples and the trading price of our common stock, or other events such as reductions in future contract awards or significant adverse changes in our operating margins or operating results of acquired businesses that vary significantly from projected results on which purchase prices are based, could result in an impairment of goodwill or other intangible assets. Any such impairments that result in us recording additional goodwill impairment charges could have a material adverse effect on our financial position or results of operations.
 
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 various jurisdictions. Significant judgment is required in determining our provision for income taxes. In the ordinary course of business, the ultimate tax determination of many of our transactions and calculations is uncertain. In addition, timing differences in the recognition of contract income for financial statement purposes and for income tax purposes can cause uncertainty with respect to the timing of income tax payments, which can have a significant impact on cash flow in a particular period. Changes in applicable income tax laws and regulations, or their interpretation, could result in higher or lower income tax rates or changes in the taxability of certain transactions or the deductibility of certain expenses, thereby affecting our income tax expense and profitability. In addition, the final results of any tax audits or related litigation could be materially different from our related historical income tax provisions and accruals. Changes in our tax rate as a result of changes in our overall profitability, changes in tax legislation, changes in the valuation of deferred tax assets and liabilities, changes in differences between financial statement income and taxable income, the examination of previously filed tax returns by taxing authorities, and continuing assessments of our tax exposures can also impact our tax liabilities and affect our income tax expense, profitability, and cash flow.


22


We conduct a portion of our operations through joint ventures and strategic alliances. We may have limited control over such arrangements and experience returns that are not proportional to the risks and resources we contribute.
 
We conduct some of our operations through joint ventures with business partners. In any joint venture arrangement, differences in views among the joint venture participants may result in delayed decisions or in failures to reach agreement on major issues. We and our joint venture partners may, in certain instances, fail to reach agreement on significant decisions on a timely basis, or at all. We also cannot control the actions of our joint venture partners, including any non-performance, default, or bankruptcy of our joint venture partners, and we typically share liability or have joint and/or several liability with our joint venture partners for joint venture matters. Any of these factors could potentially have a material adverse effect on our joint venture operations and the profitability of our joint ventures.
 
In joint ventures in which we hold a minority interest, we have limited control over many decisions relating to joint venture projects and internal controls relating to operations. These joint ventures may not be subject to the same requirements regarding internal controls and internal control reporting that apply to us. As a result, internal control issues may arise that could have a material adverse effect on the joint venture. In addition, in order to establish or preserve relationships with our joint venture partners, we may agree to assume risks and contribute resources that are proportionately greater than the returns we expect to receive in the related joint venture. Such agreements may reduce our income and returns on these investments compared to what we would have received if our assumed risks and contributed resources were proportionate to our returns.

Strategic acquisitions and investments we pursue involve risks and uncertainties.

In pursuing our business strategy, we review, evaluate, and consider potential acquisitions and investments. In evaluating such transactions, we have to make difficult judgments regarding the value of business opportunities, technologies, and other assets, the risks and costs of potential liabilities, and the future prospects of business opportunities. In addition, acquisitions and investments involve other risks and uncertainties, including the difficulty of integrating acquired businesses, challenges achieving strategic objectives and other benefits anticipated from acquisitions or investments, the diversion of management attention and resources from our existing operations and other initiatives, the potential impairment of acquired assets, and the potential loss of key employees of acquired businesses. Our financial results, business, and future prospects could be adversely affected by unanticipated performance issues at acquired businesses, transaction-related charges, liabilities, amortization of expenses related to purchased intangible assets, and charges for impairment of purchased intangible assets.
 
We are subject to various claims and litigation that could ultimately be resolved against us, requiring material future cash payments and/or future material charges against our operating income, materially impairing our financial position or cash flows.
 
The size, nature, and complexity of our business make it highly susceptible to claims and litigation. We are currently, and may in the future become, subject to various administrative, civil, or criminal litigation, environmental claims, income tax matters, compliance matters, claims, and investigations, which could divert financial and management resources and result in fines, penalties, compensatory, treble or other damages, or nonmonetary 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. Suspension or debarment could have a material adverse effect on us because of our reliance on government contracts and authorizations. Litigation, claims, or investigations, if ultimately resolved against us, could have a material adverse effect on our financial position, results of operations, or cash flows. Any litigation, claim, or investigation, 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.
 

23


We may be unable to adequately protect our intellectual property rights, which could affect our ability to compete.
 
We own certain 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 we develop in performance of government contracts, and it may use or authorize others to use such intellectual property. More recently, the U.S. Government has asserted or sought to obtain more extensive rights in intellectual property associated with its contracts. The U.S. Government's efforts could result in a decrease in our ability to control the use of certain of our intellectual property rights in a government contracting environment. Our intellectual property is also subject to challenge, invalidation, misappropriation, or circumvention by third parties.
 
We also rely 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, however, provide meaningful protection for our unpatented proprietary information.

In the event of infringement of our intellectual property rights, breach of a confidentiality agreement, or unauthorized disclosure of proprietary information, we may not have adequate legal remedies to maintain our rights in our intellectual property. Litigation to determine the scope of our rights, even if successful, could be costly and a diversion of management's attention from other aspects of our business. In addition, trade secrets may otherwise become known or be independently developed by competitors. If we are unable adequately to protect our intellectual property rights, our business could be adversely affected.
 
We have the right to use certain intellectual property licensed to us by third parties. In instances where third parties have licensed to us the right to use their intellectual property, we may be unable in the future to secure the necessary licenses to use such intellectual property on commercially reasonable terms.

Our debt exposes us to certain risks.

As of December 31, 2015, we had $1,273 million of debt and $1,223 million of additional borrowing capacity under our Second Amended and Restated Credit Agreement (the “Amended Credit Facility”). Our current level of debt could have important consequences, including:

Increasing our vulnerability to adverse economic or industry conditions;
Requiring us to dedicate a portion of our cash flow from operations to payments on our debt, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, strategic initiatives, and general corporate purposes;
Increasing our vulnerability to, and limiting our flexibility in planning for, or reacting to, changes in our business or the industries in which we operate;
Exposing us to the risk of higher interest rates, to the extent borrowings under our Amended Credit Facility are subject to variable rates of interest;
Placing us at a competitive disadvantage compared to our competitors that have less debt; and
Limiting our ability to borrow additional funds.

Because we use a portion of our cash flow from operations to service our debt, we could fail to generate sufficient cash to fund our liquidity needs or fail to satisfy the restrictive covenants and borrowing limitations to which we are subject under our various debt arrangements. Moreover, we have significant additional borrowing capacity and may be able to incur significant additional debt in the future. To the extent new debt is added to our current debt levels, the related risks that we face could be increased.

Restrictive covenants in the indentures governing our senior notes and our Amended Credit Facility may restrict our ability to pursue our business strategies.

The terms of our Amended Credit Facility limit our ability, among other things, to:

Incur additional debt;
Pay dividends or make other distributions on, or repurchase or redeem, our stock;
Prepay, redeem, or repurchase certain of our debt;

24


Make investments;
Consolidate, merge, sell, or otherwise dispose of all or substantially all of our assets; and
Incur liens.

The indentures governing our two tranches of 5.000% senior notes limit our ability, among other things, to:

Consolidate, merge, sell, or otherwise dispose of all or substantially all of our assets; and
Incur liens.

In addition, the terms of our Amended Credit Facility require us to maintain a maximum leverage ratio. These covenants may restrict our financial flexibility, limit our strategic initiatives, restrict our ability to grow, or limit our ability to respond to competitive changes. These covenants may affect how we conduct our business, and we may be unable to engage in favorable business activities or finance future operations or capital needs. These covenants may, therefore, affect our ability to successfully execute our business strategy and operate our business.

Our spin-off from Northrop Grumman exposes us to potential liabilities, including U.S. federal income tax liabilities.
 
Our spin-off from Northrop Grumman was structured to minimize the likelihood that Northrop Grumman, Northrop Grumman's stockholders, and we would be required to recognize any taxable income, gain, or loss for U.S. federal income tax purposes as a result of the spin-off, except with respect to cash received by Northrop Grumman's stockholders in lieu of fractional shares. If all or a portion of the spin-off does not qualify as a tax-free transaction, Northrop Grumman would recognize a substantial gain for U.S. federal income tax purposes. In such case, under IRS regulations, each member of Northrop Grumman's consolidated group at the time of the spin-off, including us and our subsidiaries, would be severally liable for the resulting U.S. federal income tax liability.

In connection with the spin-off, Northrop Grumman and we agreed that each of us would be responsible for the debts, liabilities, and other obligations related to the respective business or businesses that we own and operate following the spin-off. Although we do not expect to be liable for any such obligations not expressly assumed by us, it is possible that a court would disregard the agreed allocation and require that we assume responsibility for obligations allocated to Northrop Grumman, such as certain tax and/or environmental liabilities, particularly if Northrop Grumman were to refuse or be unable to pay or perform its allocated obligations.

Anti-takeover provisions in our organizational documents and Delaware law, as well as regulatory requirements, could delay or prevent a change in control.
 
Certain provisions of our Restated Certificate of Incorporation and Restated Bylaws may delay or prevent a merger or acquisition that stockholders may consider favorable. For example, our Restated Certificate of Incorporation and Restated Bylaws currently provide for a classified board of directors, require advance notice for stockholder proposals and director nominations, and authorize our board of directors to issue one or more series of preferred stock. These provisions may discourage acquisition proposals or delay or prevent a change in control, which could harm our stock price. Delaware law also imposes restrictions on mergers and other business combinations between any holder of 15% or more of our outstanding common stock and us.

Our nuclear shipbuilding operations are considered vitally important to the U.S. Navy. Consequently, the U.S. Navy has required us to include in our contracts with the Navy provisions regarding notice and approval rights in the event of a change of control of our nuclear shipbuilding operations and regarding the Navy's obligations to indemnify us for losses relating to our nuclear work for the Navy.  Such provisions require us to provide the U.S. Navy with notice of any potential change of control of our nuclear shipbuilding operations and obtain the Navy's consent for transferring certain related licenses, to facilitate the Navy's ability to ensure that a potential buyer would continue to conduct our operations in a satisfactory manner. We have included such provisions in solicitations for future U.S. Navy nuclear work, and we expect them to be included in future contracts with the Navy for nuclear work.
 
Provisions of our Restated Certificate of Incorporation and our Restated Bylaws and our existing contracts with the U.S. Navy may have the effect of discouraging, delaying, or preventing a change of control of our company that may be beneficial to our stockholders.

ITEM 1B. UNRESOLVED STAFF COMMENTS

There were no unresolved staff comments.

ITEM 2. PROPERTIES

Our principal properties are located in San Diego, California; Broomfield, Colorado; Avondale (New Orleans), Louisiana; Pascagoula, Mississippi; Houston, Texas; Hampton, Newport News, Suffolk, and Virginia Beach, Virginia; and Washington, D.C.
 
Ingalls - The properties comprising our Ingalls operating segment are located in Pascagoula, Mississippi, and Avondale and Waggaman, Louisiana. In March 2015, we sold the Gulfport Composite Center of Excellence to the Mississippi State Port Authority.

Our Pascagoula shipyard is a primary builder of major surface warships for the U.S. Navy and has modernized dozens of other naval ships. It is the only U.S. shipyard in recent years to be developing and building six different classes of ships for the U.S. Navy and U.S. Coast Guard. Our facilities in Pascagoula are located on approximately 800 acres on the banks of the Pascagoula River where it flows into the Mississippi Sound. We lease the west bank of our Pascagoula shipyard from the State of Mississippi pursuant to a 99-year lease, consisting of a 40-year base term plus six optional terms. We anticipate continued use of this facility for the remaining 51 years of the lease and beyond.
 
In October 2014, we ceased shipbuilding construction operations at the Avondale facility. Our Avondale shipyard is located on approximately 268 acres on the banks of the Mississippi River, approximately 12 miles upriver from downtown New Orleans. Approximately 20% of the Avondale shipyard is leased from several third parties. The leases have varying expiration dates and typically contain renewal rights. The Avondale shipyard site has the capacity to manufacture large amphibious assault ships and military and commercial transport vessels, and includes three outfitting docks totaling more than 6,000 linear feet. In addition to the shipyard, the Avondale facilities include the Maritime Technology Center of Excellence.

Newport News - The primary properties comprising our Newport News operating segment are located in Newport News, Virginia. 

Our facilities in Newport News are located on approximately 550 acres that we own near the mouth of the James River, which adjoins the Chesapeake Bay, the premier deep-water harbor on the east coast of the United States. Our Newport News shipyard is one of the largest in the United States. It is the sole designer, builder, and refueler of nuclear-powered aircraft carriers and one of only two shipyards capable of designing and building nuclear-powered submarines for the U.S. Navy. The shipyard also provides services for naval and commercial vessels.

Our Newport News shipyard includes seven graving docks, a floating dry dock, two outfitting berths, five outfitting piers, and various other shops. It also has a variety of other facilities, including an 18-acre all-weather steel fabrication shop, accessible by both rail and transporter, module outfitting facilities that enable us to assemble a ship's basic structural modules indoors and on land, machine shops totaling 300,000 square feet, and an apprentice school, which provides a four-year accredited apprenticeship program to train shipbuilders.

Our Newport News segment also includes CMSD facilities in San Diego, California, AMSEC facilities in Virginia Beach, Virginia, NNI facilities in Newport News, Virginia, and SN3 facilities in Broomfield, Colorado.
 
Other - The properties comprising our Other segment are located in Houston, Texas; Calgary, Canada; Aberdeen, Scotland; and San Juan, Trinidad and Tobago.

We believe that substantially all of our plants and equipment are, in general, well maintained and in good operating condition. We believe they are adequate for present needs and, as supplemented by planned construction, are expected to remain adequate for the foreseeable future.

ITEM 3. LEGAL PROCEEDINGS

U.S. Government Investigations and Claims - Departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of our company, and the results of such investigations may lead to administrative, civil, or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments, or compensatory, treble, or other damages. U.S. Government regulations provide that certain findings against a contractor may also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. Any suspension or debarment would likely have a material effect on us because of our reliance on government contracts.

In January 2013, we disclosed to the DoD, including the U.S. Navy, and the U.S. Department of Homeland Security, including the U.S. Coast Guard, pursuant to the FAR, that we had initiated an internal investigation regarding whether certain employees at Ingalls mischarged time or misstated progress on Navy and Coast Guard contracts. We conducted an internal investigation, led by external counsel, and have taken remedial actions, including the termination of employees in instances where we believed grounds for termination existed. We provided information regarding our investigation to the relevant government agencies. We agreed with the U.S. Navy and U.S. Coast Guard that they would initially withhold $24 million in payments on existing contracts pending receipt of additional information from our internal investigation. The U.S. Navy has reduced its portion of the withhold from $18.2 million to $4.7 million, while expressing its view that the gross amount of potential mischarging incurred by the Navy will likely not exceed $3.1 million. The U.S. Coast Guard informed us in June 2014 that it was provisionally reducing its withhold from $5.8 million to $3.6 million. Based on the results of our internal investigation, we estimate that the maximum amount of U.S. Navy and Coast Guard mischarging is approximately $4 million. We are continuing discussions with our U.S. Government customers regarding the potential release of an additional portion of the withheld funds, but we cannot predict whether or when these customers will agree to any additional release of the withhold amounts.

In June 2015, the DoJ informed us that it is investigating the matters we disclosed to the DoD in January 2013. In July 2015, the DoJ requested information from us, and we are cooperating with the DoJ’s requests and have provided certain information to the DoJ. Depending upon the outcome of this matter, which could result in litigation by the DoJ against us, we could be subject to civil penalties, damages, and/or suspension or debarment from future U.S. Government contracts, which could have a material effect on our consolidated financial position, results of operations, or cash flows. Given the early stage of our discussions with the DoJ, we are currently unable to estimate an amount or range of reasonably possible loss or to express an opinion regarding the ultimate outcome of this matter.

Litigation - We are party to various claims and legal proceedings that arise in the ordinary course of business. Although we believe that the resolution of any of these various claims and legal proceedings will not have a material effect on our consolidated financial position, results of operations, or cash flows, we cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of these matters.
 
In 2013, we resolved litigation against an insurance provider, Factory Mutual Insurance Company ("FM Global"), arising out of a disagreement concerning the coverage of certain losses related to Hurricane Katrina. In January 2011, we, through a predecessor-in-interest, filed suit in Superior Court in California against Aon Risk Insurance Services West, Inc. ("Aon"), which acted as broker to our predecessor-in-interest in connection with the insurance policy with FM Global, seeking damages for breach of contract, professional negligence and negligent misrepresentation, as well as declaratory relief. Those included damages unrecovered from FM Global plus costs, legal fees, and expenses incurred in the lawsuit against FM Global, as well as interest. In January 2014, we amended our complaint to allege fraud and seek punitive damages. In May 2015, we entered into a settlement agreement with Aon, pursuant to which Aon made a cash payment of $150 million to us and we released our claims against Aon.

In January 2011, the U.S. Department of Justice ("DoJ") first informed us through Northrop Grumman of a False Claims Act complaint (the "Complaint") that was filed under seal in the U.S. District Court for the District of Columbia. The redacted copy of the Complaint we received alleges that, through largely unspecified fraudulent means, we and Northrop Grumman obtained federal funds that were restricted by law for the consequences of Hurricane Katrina, and used those funds to cover costs under certain shipbuilding contracts that were unrelated to Katrina and for which Northrop Grumman and we were not entitled to recovery under the contracts. The Complaint

27


seeks monetary damages of at least $835 million, plus penalties, attorneys' fees and other costs of suit. Damages under the False Claims Act may be trebled upon a finding of liability.
 
In July 2012, the District Court entered an order permitting us to disclose certain information not included in the redacted copy of the Complaint received by us, including the date the Complaint was filed, the decision of the DoJ to decline intervention in the case, and the principal parties involved in the case. The Complaint was filed on June 2, 2010, by relators Gerald M. Fisher and Donald C. Holmes. In December 2011, the DoJ filed a Notice of Election to Decline Intervention in the case. As of August 29, 2012, Gerald M. Fisher was no longer a relator in or party to this case. In February 2013, the U.S. District Court for the District of Columbia granted the defendants' motion to transfer venue, and the case was transferred to the U.S. District Court for the Southern District of Mississippi. We filed a motion to dismiss the case and a motion to disqualify relator Holmes, and all other matters were stayed pending resolution of those motions. On June 3, 2015, the District Court granted our motion to disqualify Holmes as relator, dismissed the case as to Holmes, and entered final judgment in favor of us. Holmes has appealed the District Court's decision to the U.S. Court of Appeals for the Fifth Circuit.
Based upon a review to date of the information available to us, we believe that we have substantive defenses to the allegations in the Complaint, that the claims as set forth in the Complaint evidence a fundamental lack of understanding of the terms and conditions in our shipbuilding contracts, including the post-Katrina modifications to those contracts, and the manner in which the parties performed in connection with the contracts, and that the claims as set forth in the Complaint lack merit. We, therefore, believe that the claims as set forth in the Complaint will not result in a material effect on our consolidated financial position, results of operations, or cash flows. We intend to defend the matter vigorously, but we cannot predict what new or revised claims might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome.
We and our predecessors-in-interest are defendants in a longstanding series of cases that have been and continue to be filed in various jurisdictions around the country, in which former and current employees and various third parties allege exposure to asbestos-containing materials while on, or associated with, our premises or while working on vessels constructed or repaired by us. The cases allege various injuries, including those associated with pleural plaque disease, asbestosis, cancer, mesothelioma and other alleged asbestos-related conditions. In some cases, several of our former executive officers are also named as defendants. In some instances, partial or full insurance coverage is available to us for our liability and that of our former executive officers. Although we believe the ultimate resolution of these cases will not have a material effect on our consolidated financial position, results of operations, or cash flows, we cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of asbestos related litigation.

We and our predecessor-in-interest have been in litigation with the Bolivarian Republic of Venezuela (the “Republic”) since 2002 over a contract for the repair, refurbishment and modernization at Ingalls of two foreign-built frigates. The case proceeded towards arbitration, then appeared to settle favorably, but the settlement was overturned in court and the matter returned to litigation. In March 2014, we filed an arbitral statement of claim asserting breaches of the contract and $173 million in damages plus substantial interest and litigation expenses. In July 2014, the Republic filed in the arbitration a statement of defense denying all our allegations and a counterclaim alleging late redelivery of the frigates, unfinished work and breach of warranty and asserting damages of $61 million plus interest. An arbitration hearing was held in January 2015, and we cannot predict when the arbitration panel will render a decision. No assurances can be provided regarding the ultimate outcome of this matter.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

Our Business

For more than a century, we have designed, built, overhauled and repaired ships primarily for the U.S. Navy and the U.S. Coast Guard. We conduct business primarily with the U.S. Government, principally the Department of Defense ("DoD"). As prime contractor, principal subcontractor, team member, or partner, we participate in many high-priority U.S. defense technology programs. HII is organized into three reportable segments: Ingalls, Newport News, and Other. Through our Ingalls segment, we are a builder of amphibious assault and expeditionary warfare ships for the U.S. Navy, the sole builder of National Security Cutters ("NSC") for the U.S. Coast Guard, and one of only two companies that builds the Navy's current fleet of DDG-51 Arleigh Burke-class destroyers. Through our Newport News segment, we are the nation's sole designer, builder, and refueler of nuclear-powered aircraft carriers, and one of only two companies currently designing and building nuclear-powered submarines for the U.S. Navy. Our Other segment was established in the second quarter of 2014 to account for certain of our non-shipbuilding commercial activities.

The following discussion should be read along with the audited consolidated financial statements included in this Annual Report on Form 10-K.

Business Environment

In August 2011, the BCA reduced the DoD top line budget by $487 billion from fiscal year 2012 through 2021. Additionally, because Congress did not identify savings to reduce the U.S. deficit by up to $1.2 trillion prior to March 1, 2013, budgetary sequestration was implemented under the BCA. Sequestration requires an additional reduction from fiscal year 2012 through 2021 of $500 billion for defense spending and $500 billion for non-defense discretionary spending, including the U.S. Coast Guard.

In December 2013, the President signed into law the BBA 2013, which provided $63 billion in sequestration relief over two years, split evenly between defense and non-defense programs, and set overall discretionary spending at $1.012 trillion and $1.013 trillion for fiscal years 2014 and 2015, respectively. On November 2, 2015, the President signed into law the BBA 2015, which provided $80 billion in sequestration relief over two years, split evenly between defense and non-defense programs. The BBA 2015 provided sequestration relief of $50 billion and $30 billion for fiscal years 2016 and 2017, respectively, resulting in overall discretionary spending caps of $1.067 trillion and $1.070 trillion for fiscal years 2016 and 2017, respectively. Sequestration remains in effect under the BCA for fiscal years 2018 through 2021. Enactment of the BBA 2015 enabled the House and Senate Appropriations Committees to agree upon final appropriations levels and enabled final passage and enactment of the Consolidated Appropriations Act of 2016, which provided general spending for most of the U.S. federal government, including the DoD, DoE, and the Department of Homeland Security.

The Consolidated Appropriations Act of 2016 specifically provided funding for construction of CVN-79 John F. Kennedy, advance procurement funding for CVN-80 Enterprise, construction of two SSN-774 Virginia-class submarines, procurement for the CVN-73 USS George Washington RCOH, advance procurement for the CVN-74 USS John C. Stennis RCOH, continuation of DDG-51 Arleigh Burke-class destroyer production, advance procurement for LHA-8 (unnamed), procurement of an additional LPD-17 San Antonio-class warship, advance procurement to accelerate the LXR program, RDT&E funding for the Ohio replacement program, procurement of a T-AO(X) fleet oiler, and procurement of an additional NSC for the U.S. Coast Guard.

While the BBA 2015 eliminated the implementation of sequestration reductions for fiscal years 2016 and 2017, uncertainty continues regarding the specific effects of sequestration in fiscal years 2018 through 2021, and related funding reductions that could result in the cancellation of or decreased funding for our existing programs and/or a lack of funding for future programs.


35


The impact of the continuing federal fiscal debates for fiscal year 2017 and beyond remains uncertain, and we cannot predict the impact that the sequestration cuts or other defense spending cuts may have on funding for our individual programs. Long-term funding for certain programs in which we participate may be reduced, delayed, or canceled. In addition, defense spending cuts and delays could adversely affect the viability of our suppliers and subcontractors and employee base. Our contracts or subcontracts under programs in which we participate may be terminated or adjusted by the U.S. Government or the prime contractor as a result of lack of government funding or reductions or delays in government funding. Significant reductions in the number of ships procured by the U.S. Navy or significant delays in funding our ship programs would have a material effect on our financial position, results of operations, or cash flows.

The budget environment, including sequestration as currently mandated, remains a significant long-term risk. Considerable uncertainty exists regarding how future budget and program decisions will develop and what challenges budget reductions will present for the defense industry. We believe continued budget pressures will have serious negative consequences for the security of our country, the defense industrial base, including us, and the customers, employees, suppliers, subcontractors, investors, and communities that rely on companies in the defense industrial base. Although it is difficult to determine specific impacts, we expect that over the longer term, the budget environment may result in fewer contract awards and lower revenues, profits, and cash flows from our U.S. Government contracts. Congress continues to discuss various options to address sequestration in future budget planning, but we cannot predict the outcome of these efforts. It is likely budget and program decisions made in this environment will have long-term impacts on us and the entire defense industry.

Defense Industry Overview
 
The United States faces a complex, uncertain, and rapidly changing national security environment. The defense of the United States and its allies requires the ability to respond to constantly evolving threats, terrorist acts, regional conflicts, and cyber attacks, responses to which are increasingly dependent on early threat identification. National responses to such threats can require unilateral or cooperative initiatives that include dissuasion, deterrence, active defense, security and stability operations, and peacekeeping. We believe the U.S. Government will continue to place a high priority on the protection of its engaged forces and citizenry and on minimizing collateral damage when force must be applied in pursuit of national objectives.

The United States' engagement in combating terrorism around the world, coupled with the need to modernize U.S. military forces, has driven DoD funding levels since 2001. In March 2014, the DoD released its Report of the Quadrennial Defense Review ("QDR"), a legislatively-mandated review of military strategy and priorities that shapes defense funding over the ensuing four years. The QDR built upon the 2012 Defense Strategic Guidance, prioritizing three strategic pillars: defending the homeland; building security globally by projecting U.S. influence and deterring aggression; and remaining prepared to win decisively against any adversary should deterrence fail. Guided by this updated defense strategy, DoD plans to rebalance the military over the next decade and put it on a sustainable path to protect and advance U.S. interests and sustain U.S. global leadership.

We expect that the DoD execution of its strategy will require an affordable balance between investments in current missions and investments in new capabilities to meet future challenges. The DoD faces the additional challenge of recapitalizing equipment and rebuilding readiness at a time when the DoD is pursuing modernization of its capabilities, while facing additional major budget cuts that began in 2013. While the BBA 2015 established new budget caps and provided sequestration relief for fiscal years 2016 and 2017, it is unclear how sequestration could impact programs for 2018 and beyond. BCA spending caps could have a significant impact on future spending plans for defense and non-defense discretionary programs. Decreases in the proposed funding levels for our programs could negatively impact our financial position, results of operations, or cash flows, including revenues, goodwill, and long-lived assets.

In March 2015, the U.S. Navy released its 2016 Shipbuilding Plan, which anticipates a fleet of 308 ships comprised of 12 ballistic missile submarines, 11 nuclear-powered aircraft carriers, 48 nuclear-powered attack submarines, 88 large multi-mission surface combatants, 52 small multi-role surface combatants, 34 amphibious landing ships, 29 combat logistics force ships, and 34 support vessels. The 2016 Shipbuilding Plan also notes that the four SSGN currently in service will retire in the mid-2020s, and the U.S. Navy is exploring the possibility of inserting a quad-pack of large diameter payload tubes in Block V SSN-774 Virginia-class submarines to offset the loss of the SSGN strike capability. The 2016 Shipbuilding Plan also acknowledges that the DoD will encounter several challenges in executing the plan, particularly with regard to funding new submarines to replace the Ohio-class nuclear ballistic submarines. Significant reductions in the number of ships procured by the U.S. Navy would have a material effect

36


on our financial position, results of operations, or cash flows. It is anticipated that the U.S. Navy will submit a shipbuilding plan to Congress subsequent to submission of the Fiscal Year 2017 President's Budget Request, which will provide additional details regarding the force structure.

The shipbuilding defense industry, as characterized by its competitors, customers, suppliers, potential entrants, and substitutes, is unique in many ways. It is heavily capital and skilled labor intensive. The U.S. Navy, a large single customer with many needs and requirements, dominates the industry's customer base and is served by a supplier base that has trended toward exclusive providers. Smaller shipyards, however, have entered the market to build the U.S. Navy's new LCS. The U.S. Navy must compete with other national priorities, including other defense activities and entitlement programs, for a share of federal budget funding.

The DoD continues to adjust its procurement practices, requirements criteria, and source selection methodology in an ongoing effort to reduce costs, gain efficiencies, and enhance program management and control. The most recent initiatives, included in the September 2014 BBP 3.0, are organized into eight major areas: achieve affordable programs; achieve dominant capabilities while controlling lifecycle costs; incentivize productivity in industry and government; incentivize innovation in industry and government; eliminate unproductive processes and bureaucracy; promote effective competition; improve tradecraft in acquisition of services; and improve the professionalism of the total acquisition workforce. While the impact to our business resulting from these initiatives remains uncertain, they could have a material impact on current programs, as well as new business opportunities with the DoD. See Risks Related to Our Business in Item 1A.

Program Descriptions
 
For convenience, a brief description of certain programs discussed in this Annual Report on Form 10-K is included in the Glossary of Programs.

CONTRACTS

We generate most of our revenues from long-term U.S. Government contracts for design, production, and support activities. Government contracts typically include the following cost elements: direct material, labor and subcontracting costs, and certain indirect costs, including allowable general and administrative expenses. Unless otherwise specified in a contract, costs billed to contracts with the U.S. Government are treated as allowable and allocable costs under the FAR and CAS regulations. Examples of costs incurred by us that are not allowable under the FAR and CAS regulations include certain legal costs, lobbying costs, charitable donations, interest expense, and advertising costs.

We monitor our policies and procedures with respect to our contracts on a regular basis to ensure consistent application under similar terms and conditions as well as compliance with all applicable government regulations. In addition, the DCAA routinely audits the costs we incur that are allocated to contracts with the U.S. Government.

Our long-term contracts typically fall into one of two broad categories:

Flexibly-Priced Contracts - Includes both cost-type and fixed-price incentive contracts. Cost-type contracts provide for reimbursement of the contractor's allowable costs plus a fee that represents profit. Cost-type contracts generally require that the contractor use its reasonable efforts to accomplish the scope of the work within some specified time and some stated dollar limitation. Fixed-price incentive contracts also provide for reimbursement of the contractor's allowable costs, 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. Approximately 95%, 94% and 98% of our revenues for the years ended December 31, 2015, 2014 and 2013, respectively, were generated from flexibly-priced contracts, including certain fixed-price incentive contracts that have exceeded their cost-share limit.

Firm 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 predetermined by bid or negotiation and not generally subject to adjustment regardless of costs incurred by the contractor. Time and materials contracts, which specify a fixed hourly rate for each labor hour charged, are considered firm fixed-price contracts. Approximately 5%, 6% and 2% of our revenues for the years ended December 31, 2015, 2014 and 2013, respectively, were generated from firm fixed-price arrangements.


37


Contract Fees - Negotiated contract fee structures for both flexibly-priced and firm fixed-price contracts include: fixed fee amounts, cost sharing arrangements to reward or penalize contractors for under or over cost target performance, respectively, positive award fees and negative penalty arrangements. Profit margins may vary materially depending on the negotiated contract fee arrangements, percentage-of-completion of the contract, 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.

Award Fees - Certain contracts contain award fees 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 our performance against such negotiated criteria. Fees that we are reasonably assured of collecting and can be reasonably estimated are recorded over the performance period of the contract.

CRITICAL ACCOUNTING POLICIES, ESTIMATES, AND JUDGMENTS

Our consolidated financial statements are prepared in accordance with GAAP, which requires management to make estimates, judgments, and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Management considers an accounting policy to be critical if it is important to our financial condition and results of operations and requires significant judgment and estimates by management in its application. The development and selection of these critical accounting policies have been determined by our management. We have reviewed our critical accounting policies and estimates with the audit committee of our board of directors. Due to the significant judgment involved in selecting certain of the assumptions used in these areas, it is possible that different parties could choose different assumptions and reach different conclusions. We consider the policies relating to the following matters to be critical accounting policies:

Revenue recognition;
Purchase accounting, goodwill, and intangible assets;
Litigation, commitments, and contingencies;
Retirement related benefit plans; and
Workers' compensation.

Revenue Recognition
 
Overview - Most of our revenues are derived from long-term contracts for the production of goods and services provided to the federal government, which are accounted for in conformity with GAAP for construction-type and production-type contracts and federal government contractors. We have other types of contracts, such as services and commercial arrangements, for which revenues are recognized upon delivery or as services are rendered once persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectibility is reasonably assured. Costs related to these contracts are expensed as incurred. We classify contract revenues as product sales or service revenues depending on the predominant attributes of the relevant underlying contracts. 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 - We generally recognize revenues from our long-term contracts under the cost-to-cost measure of the percentage-of-completion method of accounting. The percentage-of-completion method recognizes income as work on a contract progresses. For most contracts, we calculate sales based on the percentage of costs incurred in relation to total Estimated Costs at Completion of the contract ("EAC"). For certain contracts with large up-front purchases of material, sales are calculated based on the percentage that direct labor costs incurred bear to total estimated direct labor costs at completion. For certain contracts that provide for deliveries of a substantial number of similar units, sales are accounted for using units of delivery as the basis to measure progress toward completion.

The use of the percentage-of-completion method depends on our ability to make reasonably dependable cost estimates for the design, manufacture, and delivery of our products and services. Such costs are typically incurred over a period of several years, and estimation of these costs requires the use of judgment. We record sales under cost-type contracts as costs are incurred.


38


Many contracts contain positive and negative profit incentives based upon performance relative to predetermined targets that may occur during or subsequent to delivery of the product. These incentives take the form of potential additional fees to be earned or penalties to be incurred. Incentives and award fees that we are reasonably assured of collecting and can be reasonably estimated are recorded over the performance period of the contract. Incentives and award fees that we are not reasonably assured of collecting or cannot be reasonably estimated are recorded when awarded or at such time as a reasonable estimate can be made.

At the start of each contract, we estimate an initial profit-booking rate that considers risks related to technical requirements and feasibility, schedule, and contract costs. Management then performs periodic reviews of our contracts in order to evaluate technical matters, schedule, and contract costs. During the life of a contract, the profit-booking rate may increase as we are able to retire risks in connection with technical matters, schedule, and contract costs. Conversely, if we are not able to retire these risks, our EAC may increase, resulting in a lower profit-booking rate.

Changes in estimates of contract sales, costs, and profits are recognized using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes in current and prior periods. Hence, the effect of the changes in future periods of contract performance is recognized as if the revised estimate had been the original estimate. A significant change in an estimate on one or more contracts in a period could have a material effect on our consolidated financial position or results of operations for that period.

For the years ended December 31, 2015, 2014 and 2013, favorable and unfavorable cumulative catch-up adjustments were as follows:

For the year ended December 31, 2015, favorable cumulative catch-up adjustments were primarily related to risk retirement on the SSN-774 Virginia-class submarine program, the Legend-class NSC program, and the LPD-17 San Antonio-class program, including delivered ships, the resolution of outstanding contract changes on the LHA-6 America-class program and the CVN-71 USS Theodore Roosevelt RCOH, and contract impacts of the Aon litigation settlement. During the same period, unfavorable cumulative catch-up adjustments included lower performance on CVN-78 Gerald R. Ford, as well as other individually insignificant adjustments.

For the year ended December 31, 2014, favorable cumulative catch-up adjustments were primarily related to risk retirement on the SSN-774 Virginia-class submarine program, the Legend-class NSC program, the LPD-17 San Antonio-class program, including delivered LPD ships, and the construction contract for CVN-78 Gerald R. Ford. During the same period, none of the unfavorable cumulative catch-up adjustments were individually significant.

For the year ended December 31, 2013, favorable cumulative catch-up adjustments were primarily related to the SSN-774 Virginia-class submarine program, driven by risk retirement, performance improvement, and the favorable resolution of outstanding contract changes, risk retirement on the execution contract for the CVN-71 USS Theodore Roosevelt RCOH, and risk retirement on the Legend-class NSC program. For the same period, unfavorable cumulative catch-up adjustments were primarily related to the closing of our Gulfport facility, costs and delays on LHA-6 America associated with the remediation of mechanical issues identified during testing, as well as unfavorable performance on LPD-25 Somerset, including costs and delays associated with repairing damage caused by underwater debris during preparation for sea trials.

Cost Estimation - The cost estimation process requires significant judgment and is based upon the professional knowledge and experience of our engineers, program managers, and financial professionals. Factors we consider in estimating the work to be completed and ultimate contract recovery 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 of materials, the effect of any delays in performance, the availability and timing of funding from the customer, and the recoverability of any claims included in the estimates to complete. A significant change in an estimate on one or more contracts in a period could have a material effect on our consolidated financial position or results of operations

39


for that period, and, where such changes occur, separate disclosure is made of the nature, underlying conditions, and financial impact of the change. We update our contract cost estimates at least annually and more frequently as determined by events or circumstances. We review and assess our cost and revenue estimates for each significant contract on a quarterly basis.

We record a provision for the entire loss on a contract in the period the loss is determined when estimates of total costs to be incurred on the contract exceed estimates of total revenues to be earned. We offset loss provisions first against costs that are included in unbilled accounts receivable or inventoried costs, with any remaining amount reflected in other current liabilities.

Purchase Accounting, Goodwill, and Intangible Assets
Goodwill - Goodwill represents the purchase price paid in excess of the fair value of identifiable net tangible and intangible assets acquired in a business combination. The amount of our goodwill as of December 31, 2015 and 2014, was $956 million and $1,026 million, respectively.

Tests for Impairment - We perform impairment tests for goodwill as of November 30 of each year, or when evidence of potential impairment exists. When testing goodwill, we first compare the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit is determined to be less than the carrying value, we perform a second step to estimate the fair value of goodwill, based in part on the fair value of the underlying operations. We record a charge to operations when we determine that the recorded amount of goodwill exceeds its fair value during this second step.

We estimate the fair value of each reporting unit using a combination of discounted cash flow analysis and market based valuation methodologies. Determining fair value requires the exercise of significant judgment, including judgments about projected revenues, operating expenses, working capital investment, capital expenditures, and cash flows over a multi-year period. The discount rate applied to our forecasts of future cash flows is based on our estimated weighted average cost of capital. In assessing the reasonableness of our determined fair values, we evaluate our results against our market capitalization. Changes in these estimates and assumptions could materially affect the determination of fair value and/or goodwill impairment for each reporting unit.

November 30, 2015 Impairment Test - In connection with our annual goodwill impairment test, we tested goodwill for each of our four reporting units. As a result of our annual goodwill impairment test, we determined that the estimated fair value of each reporting unit exceeded by more than 10% its corresponding carrying value as of November 30, 2015, except for the Oil and Gas reporting unit in our Other segment.

December 31, 2015 Impairment Test - While the November 30, 2015, annual impairment test did not result in an impairment, considering the limited excess fair value of goodwill over its carrying value in our Oil and Gas reporting unit and the continued decline in oil prices and related industry activity levels, we performed an interim assessment of goodwill as of December 31, 2015. Our determination of fair value as of December 31, 2015, considered industry events that occurred in the period since our annual goodwill impairment test, as well as the updated long term outlook for this reporting unit. Those events included continued deterioration in the oil and gas markets, numerous industry-wide project deferrals, and capital spending cuts announced by industry leaders. The analysis concluded the fair value of this reporting unit was less than its carrying value as of December 31, 2015, and we recorded a goodwill impairment charge of $16 million at our Other segment in the fourth quarter of 2015.

May 31, 2015 Impairment Test - We continuously monitor industry events and changes in circumstances in the industries in which our reporting units conduct business. In consideration of the Oil and Gas reporting unit’s sensitivity to developments within its industry, the continued decline in crude oil prices, significant reductions in its customer capital spending plans, and project delays, we concluded an interim goodwill impairment test was necessary to determine whether it was more likely than not that the fair value of our Oil and Gas reporting unit was still higher than its carrying value as of May 31, 2015. Our assessment considered the aforementioned changes to expectations that were considered as part of our annual goodwill impairment test as of November 30, 2014. As a result of our analysis, we recorded a $59 million goodwill impairment charge at our Other segment in the second quarter of 2015.

November 30, 2014 Impairment Test - We performed our annual goodwill impairment testing as of November 30, 2014, and determined that goodwill at our Other segment was impaired by $47 million. The goodwill impairment

40


charge was primarily driven by the drop in oil prices and the resulting decrease in industry market multiples. We determined that the estimated fair value of our remaining reporting units significantly exceeded their corresponding carrying values as of November 30, 2014.

Other Intangible Assets - We perform tests for impairment of amortizable intangible assets whenever events or circumstances suggest that amortizable intangible assets may be impaired.

December 31, 2015 Impairment Test - We performed an impairment test as of December 31, 2015, on the amortizable intangible assets that arose from the UPI acquisition, which reside in our Oil and Gas reporting unit within our Other segment. The Oil and Gas asset group’s long-lived intangible assets consist primarily of customer relationships and, to a lesser degree, trade name and developed technology. We performed our impairment test considering the latest market conditions and expectations, as well as lower anticipated revenue and profitability. Based on the nature of UPI's intangible assets, we performed the recoverability test at the reporting unit level. In connection with the recoverability test, we reevaluated the remaining useful lives of the intangible assets and determined the total undiscounted pretax cash flows generated by the reporting unit over the remaining useful life of the primary asset, customer relationships. The carrying amount of the reporting unit was greater than the total undiscounted pretax cash flows, and, as a result, the intangible assets were written down by $27 million, charged against cost of sales and service revenues within income from operations at our Other segment.
 
Litigation, Commitments and Contingencies
 
Overview - We are subject to a range of claims, lawsuits, environmental and income tax matters, and administrative proceedings that arise in the ordinary course of business. Estimating liabilities and costs associated with these matters requires judgment and assessment based upon professional knowledge and the experience of management and our internal and external legal counsel. In accordance with our practices relating to accounting for contingencies, we record amounts as charges to earnings when we determine, after taking into consideration the facts and circumstances of each matter, including any settlement offers, that it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. The ultimate resolution of any such exposure may vary from earlier estimates as further facts and circumstances become known.
 
Environmental Accruals - We are subject to the environmental laws and regulations of the jurisdictions in which we conduct operations. We record a liability for the costs of expected environmental remediation obligations when we determine that it is probable we will incur such costs and the amount of the liability can be reasonably estimated. When a range of costs is possible and no amount within that range is a better estimate than another, we record the minimum amount of the range.
 
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 extensive contamination than anticipated, results of efforts to involve other legally responsible parties, financial insolvency of other responsible parties, changes in laws and regulations or contractual obligations affecting remediation requirements, and improvements in remediation technology. Although we cannot predict whether new information gained as remediation projects progress will materially affect the accrued liability, we do not believe that future remediation expenditures will have a material effect on our financial position, results of operations, or cash flows.

Asset Retirement Obligations - We record all known asset retirement obligations for which the liability's fair value can be reasonably estimated, including certain asbestos removal, asset decommissioning, and contractual lease restoration obligations. Recorded amounts as of December 31, 2015 and 2014, were $18 million and $22 million, respectively, and consist primarily of obligations associated with the wind down of shipbuilding operations at our Avondale facility. See Note 2: Summary of Significant Accounting Policies in Item 8.
 
We also have known conditional asset retirement obligations related to assets currently in use, such as certain asbestos remediation and asset decommissioning activities to be performed in the future, that were not reasonably estimable as of December 31, 2015, due to insufficient information about the timing and method of settlement of the obligation. Accordingly, the fair value of these obligations has not been recorded in the consolidated financial statements. Environmental remediation and/or asset decommissioning of these facilities may be required when we cease to utilize these facilities. In addition, there may be conditional environmental asset retirement obligations that we have not yet discovered (for example, asbestos of which we have not become aware through normal business

41


operations may exist in certain buildings), and these obligations have, therefore, not been included in our consolidated financial statements.
 
Litigation Accruals - Litigation accruals are recorded as charges to earnings when management has determined, after taking into consideration the facts and circumstances of each matter, including any settlement offers, that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The ultimate resolution of any exposure may vary from earlier estimates as further facts and circumstances become known. Based upon the information available, we believe that the resolution of any of these various claims and legal proceedings will not have a material effect on our consolidated financial position, results of operations, or cash flows.
 
Uncertain Tax Positions - Uncertain tax positions meeting the more-likely-than-not recognition threshold, based on the merits of the position, are recognized in the financial statements. We recognize the amount of tax benefit that is greater than 50% likely to be realized upon ultimate settlement with the related tax authority. If a tax position does not meet the minimum statutory threshold to avoid payment of penalties, we recognize an expense for the amount of the penalty in the period the tax position is claimed or expected to be claimed in our tax return. Penalties and accrued interest related to uncertain tax positions are recognized as a component of income tax expense. See Note 13: Income Taxes in Item 8. Changes in accruals associated with uncertain tax positions are recorded in earnings in the period they are determined.

Retirement Related Benefit Plans

We recognize, on a plan-by-plan basis, the funded status of our retirement related benefit plans as an asset or liability on our balance sheet, with corresponding adjustments to after-tax accumulated other comprehensive income, and deferred tax assets or liabilities. The funded status represents the difference between the benefit obligation and the fair value of plan assets. See Note 18: Employee Pension and Other Postretirement Benefits in Item 8.

We calculate our retirement related benefit plan costs under both CAS and U.S. GAAP Financial Accounting Standards ("FAS"). The calculations under CAS and FAS require significant judgment. CAS prescribes the determination, allocation, and recovery of retirement related benefit plan costs on U.S. Government contracts through the pricing of products and services. FAS outlines the methodology used to determine retirement related benefit plan expense or income, as well as the liability, for financial reporting purposes. The CAS requirements for these costs and their calculation methodologies differ from FAS. As a result, while both CAS and FAS use assumptions in their calculation methodologies, each method results in different calculated amounts of retirement related benefit plan costs.

Retirement related benefit plan costs are allocated to our U.S. Government contracts as allowable costs based upon CAS. We recover our CAS costs through the pricing of products and services on U.S. Government contracts so that the CAS cost is recognized in segment product sales and service revenues and in the costs of those product sales and service revenues. In order to present our consolidated financial statements in accordance with FAS, we record the difference between our FAS expense and CAS cost (“FAS/CAS Adjustment”) as operating income (loss) within general and administrative expenses. For the years ended December 31, 2015 and 2014, our CAS costs in excess of FAS expenses were $104 million and $72 million, respectively, and for the year ended December 31, 2013, our FAS expense exceeded our CAS costs by $61 million.

The minimum funding requirements for our qualified pension plans are determined under the Employee Retirement Income Security Act of 1974 ("ERISA"), which is primarily based on the year's expected service cost and amortization of other previously unfunded liabilities. Effective January 1, 2011, we were subject to the funding requirements under the Pension Protection Act of 2006 ("PPA"), which amended ERISA. Under the PPA, we are required to fully fund our pension plans over a rolling seven-year period as determined annually based upon the funded status at the beginning of each year. PPA also introduced a variety of benefit restrictions that apply if a plan falls below different funded percentages, as defined by the Internal Revenue Code. In funding our plans, we consider various factors, including the minimum funding requirements, maintaining the funded status needed to avoid potential benefit restrictions and other adverse consequences, maintaining minimum CAS funding requirements, and the current and anticipated funding levels of each plan.

During 2012, the Moving Ahead for Progress in the 21st Century Act ("MAP-21") was enacted. MAP-21 included provisions for potential pension relief to plan sponsors in the form of higher interest rate assumptions that were

42


used to determine minimum funding requirements. The relief derived from these provisions was to be phased out to lower levels over the next few years. The enactment of the Highway and Transportation Funding Act (“HATFA”) in 2014 and BBA 2015 successively provided for the continuation of higher interest rate assumptions used to determine minimum funding requirements and extended the pension relief phase-out period. We consider the effects of legislation such as MAP-21, HATFA, and BBA 2015 in the context of current year and future projected funded status levels in deciding on the level of contributions to make to our plans each year.

Due to the differences in requirements and calculation methodologies between FAS and CAS, our FAS pension expense is not necessarily indicative of the funding requirements under PPA or the amounts we recover from the U.S. Government under CAS.

When PPA was enacted, it was anticipated that the amounts required to be funded would exceed government contractors' recovery of those costs under CAS. To remedy this cash flow misalignment, on December 27, 2011, the U.S. Cost Accounting Standards Board issued its final CAS Harmonization Rule ("Harmonization"). Harmonization is intended to improve the alignment of the pension cost recovered through contract pricing under CAS and the pension funding requirements under the PPA. Harmonization became effective for forward pricing purposes for contracts negotiated on or after February 27, 2012. Under Harmonization, only contracts entered into before the effective date qualify for an equitable adjustment. Price proposals for CAS covered contracts awarded on or after the effective date of February 27, 2012, reflect the effects of the rule. Harmonization affects pension costs on contracts over a phase-in period ending in 2017. Our CAS pension cost recoveries are expected to remain unaffected by the pension relief provisions offered under MAP-21, HATFA, and BBA 2015 because of the method permitted under Harmonization we use to determine the CAS interest rate, which is a current market rate.

Assumptions - We account for our retirement related benefit plans on the accrual basis under FAS. The measurements of obligations, costs, assets, and liabilities require significant judgment. We annually review our assumptions, which are set at each year end and are generally not changed during the following year unless there is a major plan event, such as an amendment, curtailment, or settlement that would trigger a remeasurement. The key assumptions in these measurements are the interest rate used to discount future benefit payments and the expected long-term rate of return on plan assets.

Discount Rate - The assumed discount rate under FAS is used to determine the retirement related benefit plan obligations and expense, and represents the hypothetical rate at which the plans' benefit obligations could be effectively settled at the measurement date. Consequently, the discount rate can be volatile from year to year. The discount rate assumption is determined for each plan by constructing a hypothetical portfolio of high quality bonds with cash flows that match the estimated outflows for future benefit payments to determine a single equivalent discount rate. Benefit payments are not only contingent on the terms of a plan, but also on the underlying participant demographics, including current age and assumed mortality. We use only bonds that are denominated in U.S. Dollars, are rated Aa or better by nationally recognized statistical rating agencies, have a minimum outstanding issue of $100 million as of the measurement date, and are not callable, convertible, or index-linked.

Taking into consideration the factors noted above, our weighted average discount rate for pensions was 4.73% and 4.34% as of December 31, 2015 and 2014, respectively. Our weighted average discount rate for other postretirement benefits was 4.58% and 4.22% as of December 31, 2015 and 2014, respectively.

Expected Long-Term Rate of Return - The expected long-term rate of return on assets is used to calculate net periodic expense, and is based on such factors as historical returns, targeted asset allocations, investment policy, duration, expected future long-term performance of individual asset classes, interest rates, inflation, portfolio volatility, investment management and administrative fees, and risk management strategies. Historical plan asset performance alone has inherent limitations in predicting future returns. While studies are helpful in understanding past and current trends and performance, the assumption is based more on long-term prospective views to avoid short-term market influences. Unless plan assets and benefit obligations are subject to remeasurement during the year, the expected return on pension assets is based on the fair value of plan assets at the beginning of the year. We used a 7.50% expected long-term rate of return assumption to record 2015 and 2014 pension expense. We will continue to use this 7.50% assumption for recording 2016 FAS pension expense.

Mortality - Mortality assumptions are used to determine the retirement related benefit obligations and expense, and represent the likelihood and duration of benefit payments to plan participants based on historical experience and projected longevity. As of December 31, 2014, we updated our mortality assumptions to reflect our recent mortality experience and the anticipated effects of future mortality improvements. The effect of the changes in the mortality

43


assumptions increased our December 31, 2014, pension related benefit obligations by approximately $54 million or 1%. The impact on other postretirement benefits was not material. The increase was treated as an actuarial loss and subject to amortization in future periods as described below. We reflected updated mortality assumptions in our CAS costs. If the IRS publishes updated mortality tables for funding purposes, our pension contributions could be affected.

Differences arising from actual experience or changes in assumptions might materially affect retirement related benefit plan obligations and the funded status. Actuarial gains and losses arising from differences from actual experience or changes in assumptions are deferred in accumulated other comprehensive income. This unrecognized amount is amortized as a component of net expense to the extent it exceeds 10% of the greater of the plan's benefit obligation or plan assets. The amortization period for actuarial gains and losses is the estimated average remaining service life of the plan participants. In 2015, the actual return on assets was approximately negative 1.00%, which was less than the expected return assumption of 7.50%. For the year ended December 31, 2015, the weighted average discount rates for our pension and other postretirement benefit plans increased by 39 and 36 basis points, respectively. These differences in asset returns and discount rates resulted in an actuarial loss of $398 million and an actuarial gain of $363 million, respectively, as of December 31, 2015.

An increase or decrease of 25 basis points in the discount rate and the expected long-term rate of return assumptions would have had the following approximate impacts on pensions:

Assuming a 7.50% expected return on asset assumption, a $50 million pension contribution is generally expected to favorably impact the current year expected return on assets by approximately $2 million, depending on the timing of the contribution.

Sensitivities to assumptions are not necessarily linear and are specific to the time periods noted.

CAS Cost - In addition to providing the methodology for calculating retirement related benefit plan costs, CAS also prescribes the method for assigning those costs to specific periods. While the ultimate liability for such costs under FAS and CAS is similar, the pattern of cost recognition is different. The key drivers of CAS pension cost include the funded status and the method used to calculate CAS reimbursement for each of our plans. A plan’s CAS pension cost can only be allocated until the plan is fully funded as defined under the CAS requirements.

Through 2013, CAS required the pension discount rate to be consistent with the expected long-term rate of return on assets assumption, which changed infrequently given its long-term nature. As a result, short-term changes in bond or other interest rates generally did not impact CAS costs. Under Harmonization the liability used to determine CAS cost is developed by comparing the liability under the previous CAS methodology and assumptions to a liability based on a discount rate derived from yields on high quality bonds. When Harmonization is fully phased in, the greater of the two liabilities will be used for CAS cost calculations. Generally, liabilities based on a discount rate of high quality bonds will be higher than liabilities calculated prior to Harmonization. The four year phase in period that commenced in 2014 requires the use of a blend of the pre and post Harmonization liabilities.

Other FAS and CAS Pension Considerations - A key driver of the difference between FAS expense and CAS cost (and consequently the FAS/CAS Adjustment) is the pattern of earnings and expense recognition for actuarial gains and losses that arise when our asset and liability experiences differ from our assumptions under each set of requirements. Under FAS, our net actuarial gains and losses exceeding the 10% corridor are amortized over the employee's average future service life of approximately 12 years. Under CAS, actuarial gains and losses were amortized over a 15-year period without regard to a corridor approach. Under Harmonization, the amortization period for CAS changed to 10 years for actuarial gains and losses beginning in 2013. Both FAS and CAS use a "market-related value" of plan assets approach to calculate the amount of deferred asset gains or losses to be amortized. Under CAS actual asset gains and losses are systematically smoothed over five years, subject to certain

44


limitations. For FAS, we do not use this smoothing method, and instead use fair value in determining our FAS expense. Accordingly, FAS expense generally reflects recent asset gains and losses faster than CAS.

Additionally, CAS cost is only recognized for plans that are not fully funded as defined under CAS. If a plan becomes or ceases to be fully funded due to our asset or liability experience, our CAS cost will change accordingly.

The FAS/CAS Adjustment in 2015 was a net benefit of $104 million, compared to a net benefit of $72 million in 2014. The favorable change was driven by the phase-in of Harmonization and better than expected 2014 asset returns, partially offset by higher FAS expense primarily due to lower discount rates at the end of 2014. The FAS/CAS Adjustment in 2013 was a net expense of $61 million. The favorable change from 2013 to 2014 was driven by lower FAS expense primarily due to higher discount rates and plan assets at the end of 2013, the full year effect of the 2013 postretirement benefits amendment, and the phase-in of Harmonization. Our projected 2016 FAS/CAS Adjustment is discussed in Consolidated Operating Results - Operating Income.

Retirement Plan Assets - Retirement plan assets are stated at fair value. Investments in equity securities (common and preferred) are valued at the last reported sales price when an active market exists. Investments in fixed-income securities are generally valued based on market transactions for comparable securities and various relationships between securities that are generally recognized by institutional traders. Investments in hedge funds, real estate investment funds, collective trust funds, and commingled funds are generally valued at their Net Asset Values ("NAV") or equivalent, which are based on the current fair value of the fund's underlying assets.

Management reviews independently appraised values, audited financial statements, and additional pricing information to evaluate the NAV or its equivalent. For the very limited group of investments for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value, additional information is obtained from the investment manager and evaluated internally to determine whether any adjustments are required to reflect fair value. See Note 18: Employee Pension and Other Postretirement Benefits, in Item 8.

Accumulated Other Comprehensive Income - Changes in assumptions and changes to plan assets and benefit obligations due to differences between actuarial assumptions and actual results are reported as actuarial gains and losses and recorded in accumulated other comprehensive income along with unrecognized prior service costs arising from plan amendments. As disclosed in Note 18: Employee Pension and Other Postretirement Benefits in Item 8, net pre-tax unrecognized actuarial losses as of December 31, 2015 and 2014 were $1,412 million and $1,447 million, respectively. The decrease in these actuarial losses in 2015 was primarily driven by an increase in the discount rates used to determine benefit obligations, which accounted for $363 million, offset by 2015 actual asset returns being less than expected by $398 million, partially offset by $88 million of amortization of previously unrecognized actuarial losses.

Net pre-tax unrecognized prior service costs (credits) as of December 31, 2015 and 2014 were $(19) million and $(20) million, respectively. These net deferred costs (credits) primarily originated from plan amendments, including those resulting from collective bargaining agreements. The decrease in unrecognized prior service costs (credits) in 2015 primarily resulted from amortization of previously accumulated prior service costs (credits).

Workers' Compensation
 
Our operations are subject to federal and state workers' compensation laws. We maintain self-insured workers' compensation plans, in addition to participating in federally administered second injury workers' compensation funds. We estimate the required liability for such claims and funding requirements on a discounted basis utilizing actuarial methods based on various assumptions, which include our historical loss experience and projected loss development factors. We periodically, and at least annually, update our assumptions based on an actuarial analysis. Related self-insurance accruals include the liability for reported claims and an estimated accrual for claims incurred but not reported. Our workers' compensation liability was discounted at 2.12% and 2.48% as of December 31, 2015 and 2014, respectively, based on future payment streams and a risk-free rate. We estimate a 100 basis points increase or decrease in the discount rate would change our workers' compensation liability by $(48) million and $57 million, respectively. The workers' compensation benefit obligation on an undiscounted basis was $825 million and $846 million as of December 31, 2015 and 2014, respectively.

Operating Performance Assessment and Reporting

We manage and assess the performance of our business based on our performance on individual contracts and programs using the financial measures referred to below, with consideration given to the Critical Accounting Policies, Estimates, and Judgments referred to in this section. Our portfolio of long-term contracts is largely flexibly-priced. Therefore, sales tend to fluctuate in concert with costs across our large portfolio of active contracts, with operating income being a critical measure of operating performance. Under FAR rules that govern our business with the U.S. Government, most types of costs are allowable, and we do not focus on individual cost groupings, such as cost of sales or general and administrative expenses, as much as we do on total contract costs, which are a key factor in determining contract operating income. As a result, in evaluating our operating performance, we look primarily at changes in sales and service revenues, as well as operating income, including the effects of significant changes in operating income as a result of changes in contract estimates and the use of the cumulative catch-up method of accounting in accordance with GAAP. This approach is consistent with the long-term life cycle of our contracts, as management assesses the bidding of each contract by focusing on net sales and operating profit and monitors performance in a similar manner through contract completion. Consequently, our discussion of business segment performance focuses on net sales and operating profit, consistent with our approach for managing our business.

Cost of sales for both product sales and service revenues consist of materials, labor and subcontracting costs, as well as an allocation of indirect costs for overhead. We manage the type and amount of costs at the contract level, which is the basis for estimating our total costs at completion of our contracts. Unusual fluctuations in operating performance driven by changes in a specific cost element across multiple contracts are described in our analysis.

Cost of Product Sales

2015 - Cost of product sales in 2015 decreased $170 million, or 4%, compared to 2014. Cost of product sales at our Ingalls segment decreased $225 million in 2015, primarily due to the settlement of the Aon litigation and the lower sales volumes described above. Cost of product sales at our Newport News segment increased $55 million in 2015, primarily due to the higher sales volumes described above and year-to-year variances in contract mix. Cost of product sales as a percentage of product sales declined from 78.6% in 2014 to 76.2% in 2015, primarily driven by the settlement of the Aon litigation, higher performance in Amphibious Assault Ships, and year-to-year variances in contract mix, partially offset by lower performance in Aircraft Carriers.

2014 - Cost of product sales in 2014 decreased $206 million, or 4%, compared to 2013. Cost of product sales at our Ingalls segment decreased $236 million in 2014, primarily due to performance improvement on the LPD-17 San Antonio-class program and the lower sales volumes described above. Cost of product sales at our Newport News segment increased $30 million in 2014, primarily due to higher sales volumes described above and year-to-year

47


variances in contract mix. Cost of product sales as a percentage of product sales declined from 80.9% in 2013 to 78.6% in 2014, primarily driven by performance improvement on the LPD-17 San Antonio-class program and risk retirement on the Legend-class NSC program.

Cost of Service Revenues

2015 - Cost of service revenues in 2015 increased $147 million, or 14%, compared to 2014. Cost of service revenues at our Ingalls segment increased $15 million in 2015, primarily as a result of the higher sales volumes described above. Cost of service revenues at our Newport News segment increased $98 million in 2015, primarily as a result of the higher sales volumes described above. Cost of service revenues at our Other segment increased $34 million in 2015, primarily as a result of an intangible asset impairment. Cost of service revenues as a percentage of service revenues increased from 84.4% in 2014 to 88.4% in 2015, primarily driven by the intangible asset impairment at the Other segment, year-to-year variances in contract mix, and lower performance in Aircraft Carriers and oil and gas services.

2014 - Cost of service revenues in 2014 increased $163 million, or 18%, compared to 2013. Cost of service revenues at our Ingalls segment decreased $20 million in 2014, consistent with the volume changes described above. Cost of service revenues at our Newport News segment increased $61 million in 2014, primarily as a result of the higher volumes described above, partially offset by the impact of a change in our contract mix following the acquisition of SN3. Cost of service revenues at our Other segment were $122 million in 2014, primarily resulting from the acquisition of UPI. Cost of service revenues as a percentage of service revenues increased from 87.1% in 2013 to 84.4% in 2014, due to year-to-year variances in contract mix primarily resulting from the acquisition of SN3.

Income (Loss) from Operating Investments, Net

The activities of our operating investments are closely aligned with the operations of the segments holding the investments. We therefore record income related to earnings from equity method investments in our operating income.

2015 - Income from operating investments, net decreased $1 million, or 9%, to $10 million in 2015 from $11 million in 2014. The decrease resulted from lower equity income from our Savannah River Nuclear Solutions, LLC investment.

2014 - Income from operating investments, net decreased $3 million, or 21%, to $11 million in 2014 from $14 million in 2013. The decrease resulted from lower equity income from our Savannah River Nuclear Solutions, LLC investment.

General and Administrative Expenses

In accordance with industry practice and the regulations that govern the cost accounting requirements for government contracts, most general and administrative expenses are considered allowable and allocable costs on government contracts. These costs are allocated to contracts in progress on a systematic basis and contract performance factors include this cost component as an element of cost.

2015 - General and administrative expenses in 2015 decreased $57 million, or 8%, compared to 2014. This decrease was primarily the result of a favorable change in the FAS/CAS Adjustment and lower overhead costs, offset by the inclusion of UPI and higher state tax expense.

2014 - General and administrative expenses in 2014 decreased $13 million, or 2%, compared to 2013. This decrease was primarily the result of a favorable change in the FAS/CAS Adjustment, partially offset by increases resulting from the amortization of Avondale restructuring costs, the inclusion of UPI and SN3, and higher state tax expense.

Impairment of Goodwill

As discussed above in Critical Accounting Policies, Estimates and Judgments, we perform impairment tests for
goodwill as of November 30 each year, or when evidence of potential impairment exists. We record a charge to operations when we determine that an impairment has occurred.


48


2015 - We recorded goodwill impairment charges in 2015 of $75 million in our Other segment. See Note 12: Goodwill and Other Purchased Intangible Assets in Item 8.

2014 - We recorded a goodwill impairment charge in 2014 of $47 million in our Other segment. See Note 12: Goodwill and Other Purchased Intangible Assets in Item 8.

2013 - We did not record any goodwill impairment charge during 2013.


Operating Income

We consider operating income to be an important measure for evaluating our operating performance, and, as is typical in the industry, we define operating income as revenues less the related cost of producing the revenues and general and administrative expenses.

We internally manage our operations by reference to "segment operating income," which is defined as operating income before the FAS/CAS Adjustment and deferred state income taxes, neither of which affects segment performance. Segment operating income is not a recognized measure under GAAP.  When analyzing our operating performance, investors should use segment operating income in addition to, and not as an alternative for, total operating income or any other performance measure presented in accordance with GAAP. It is a metric that we use to evaluate our core operating performance.  We believe that segment operating income reflects an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our business. We believe the measure is used by investors and is a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of segment operating income may not be comparable to similarly titled measures of other companies.

The following table reconciles segment operating income to total operating income:

Segment Operating Income

2015 - Segment operating income in 2015 was $667 million, compared to $585 million in 2014. The increase was primarily due to the settlement of the Aon litigation, higher performance and volumes in Submarines, and higher performance on Amphibious Assault Ships, partially offset by the goodwill and intangible asset impairment charges in the Other segment and lower performance on Aircraft Carriers.

2014 - Segment operating income in 2014 was $585 million, compared to $567 million in 2013. The increase was primarily due to performance improvement and risk retirement on the LPD-17 San Antonio-class program and the Legend-class NSC program, as well as the unfavorable impact in the prior year of the Gulfport facility closure, partially offset by the goodwill impairment charge described above and the favorable impact in the prior year of hurricane insurance recoveries.

Activity within each segment is discussed in Segment Operating Results below.

FAS/CAS Adjustment

The FAS/CAS Adjustment represents the difference between our pension and postretirement plan expense under FAS and under CAS.

2015 - The FAS/CAS Adjustment in 2015 was a net benefit of $104 million, compared to a net benefit of $72 million in 2014. The favorable change was driven by the phase-in of Harmonization and better than expected 2014 asset returns, partially offset by higher FAS expense primarily due to lower discount rates at the end of 2014.

2014 - The FAS/CAS Adjustment in 2014 was a net benefit of $72 million, compared to a net expense of $61 million in 2013. The favorable change was driven by lower FAS expense, due primarily to higher discount rates and plan assets at the end of 2013, the full year effect of the 2013 postretirement benefits amendment, and the phase-in of Harmonization.

We expect the FAS/CAS Adjustment in 2016 to be a net benefit of approximately $137 million ($161 million FAS and $298 million CAS), primarily driven by the continued phase-in of Harmonization and higher FAS discount rates, partially offset by lower than expected 2015 asset returns. The expected FAS/CAS Adjustment is subject to change during 2016, when we remeasure our actuarial estimate of the unfunded benefit obligation for CAS with updated census data and other items.

Deferred State Income Taxes

Deferred state income taxes reflect the change in deferred state tax assets and liabilities in the relevant period. These amounts are recorded within operating income, while the current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

2015 - The deferred state income tax expense remained constant at $2 million in 2015 and 2014. Deferred state tax expense in 2015 was primarily attributable to changes in the timing of contract taxable income and pension related adjustments, partially offset by a reduction in the valuation allowance for state tax credit carryforwards.

2014 - The deferred state income tax expense in 2014 was $2 million, compared to a benefit of $6 million in 2013. This change was primarily attributable to non-recurring adjustments related to establishing a valuation allowance for a state tax loss carryforward and the true-up of 2013 deferred taxes. These increases were partially offset by changes in the timing of contract taxable income and reserves that are not currently deductible for tax purposes.

Interest Expense

2015 - Interest expense in 2015 was $137 million, compared to $149 million in 2014. The decrease was primarily a result of refinancing 6.875% senior notes with 5.000% senior notes and repayment in full of the term loans, partially offset by loss on early extinguishment of debt. See Note 14: Debt in Item 8.

2014 - Interest expense in 2014 was $149 million, compared to $118 million in 2013. The increase was primarily a result of a loss on the early extinguishment of debt in the fourth quarter of 2014. See Note 14: Debt in Item 8.

Federal Income Taxes

2015 - Our effective tax rate on earnings from continuing operations was 36.1% in 2015, compared to 33.3% in 2014. The increase in our effective tax rate for 2015 was primarily attributable to adjustments to the domestic manufacturing deduction and an increase in the goodwill impairment that is not amortizable for tax purposes.


50


2014 - Our effective tax rate on earnings from continuing operations was 33.3% in 2014, compared to 33.8% in 2013. The decrease in our effective tax rate for 2014 was primarily attributable to an increase in the domestic manufacturing deduction, partially offset by the amount of the goodwill impairment that is not deductible for tax purposes.

SEGMENT OPERATING RESULTS

Basis of Presentation

We are aligned into three reportable segments: Ingalls, Newport News, and Other. We established the Other segment in the second quarter of 2014 to account for certain of our non-shipbuilding commercial activities. In the first quarter of 2014, we realigned our segments in order to optimize our operating structure. As a result of this realignment, our AMSEC and CMSD businesses were transferred from the Ingalls segment to the Newport News segment. We have reflected the 2014 realignment in prior financial reporting periods on an as-if basis, which has resulted in the transfer of revenue, operating profit, assets, and liabilities between the Ingalls and Newport News segments. None of these changes impacted our previously reported consolidated financial position, results of operations, or cash flows.

On January 30, 2015, we completed the acquisition of USG. USG's post-acquisition results of operations, financial position, and cash flows are reported within our Newport News segment. On May 30, 2014, we completed the acquisition of UPI. We report the post-acquisition results of operations, financial position, and cash flows of UPI as part of our Other segment. On January 2, 2014, we completed the acquisition of SN3. SN3's post-acquisition results of operations, financial position, and cash flows are reported within our Newport News segment.

KEY SEGMENT FINANCIAL MEASURES

Sales and Service Revenues

Period-to-period revenues reflect performance under new and ongoing contracts. Changes in sales and service revenues are typically expressed in terms of volume. Unless otherwise described, volume generally refers to increases (or decreases) in reported revenues due to varying production activity levels, delivery rates or service levels on individual contracts. Volume changes will typically carry a corresponding income change based on the margin rate for a particular contract.


51


Segment Operating Income

Segment operating income reflects the aggregate performance results of contracts within a segment. Excluded from this measure are certain costs not directly associated with contract performance, including the FAS/CAS Adjustment and deferred state income taxes. Changes in segment operating income are typically expressed in terms of volume, as discussed above, or performance. Performance refers to changes in contract margin rates. These changes typically relate to profit recognition associated with revisions to EAC that reflect improved (or deteriorated) operating performance on a particular contract. Operating income changes are accounted for on a cumulative to date basis at the time an EAC change is recorded. Segment operating income may also be affected by, among other things, contract performance, the effects of workforce stoppages, the effects of natural disasters such as hurricanes, resolution of disputed items with the customer, recovery of insurance proceeds, and other discrete events. At the completion of a long-term contract, any originally estimated costs not incurred or reserves not fully utilized, such as warranty reserves, could also impact contract earnings. Where such items have occurred and the effects are material, a separate description is provided.

Sales and Service Revenues

2015 - Ingalls revenues, including intersegment sales, decreased $98 million, or 4%, in 2015 compared to 2014, driven by lower revenues in Amphibious Assault Ships and the Legend-class NSC program, partially offset by higher revenues in Surface Combatants. The decrease in Amphibious Assault Ships revenues was due to lower volumes on LPD-26 John P. Murtha, LPD-27 Portland, and LHA-6 USS America, partially offset by higher volume on LHA-7 Tripoli. Revenues on the Legend-class NSC program decreased due to lower volumes on NSC-4 USCGC Hamilton and NSC-5 USCGC James, partially offset by higher volumes on NSC-7 Kimball and NSC-8 Midgett. Surface Combatants revenues increased due to higher volumes on DDG-119 Delbert D. Black and DDG-121 (unnamed), partially offset by lower volumes in the DDG-1000 Zumwalt-class destroyer program.

2014 - Ingalls revenues, including intersegment sales, decreased $155 million, or 6%, in 2014 compared to 2013, driven by lower revenues in Amphibious Assault Ships, partially offset by higher revenues in the Legend-class NSC program and Surface Combatants. The decrease in Amphibious Assault Ships revenues was due to lower volumes on LHA-6 USS America and LPD-25 USS Somerset, partially offset by higher volumes on LHA-7 Tripoli and LPD-26 John P. Murtha. Revenues on the Legend-class NSC program increased due to higher volumes on the construction contracts of NSC-6 Munro, NSC-7 Kimball, and NSC-5 James, partially offset by lower volumes on the construction of NSC-4 Hamilton. Surface Combatants revenues increased due to higher volumes on the construction contracts of DDG-117 Paul Ignatius, DDG-119 Delbert D. Black, and DDG-114 Ralph Johnson, partially offset by lower volumes on the DDG-1000 Zumwalt-class destroyer program.

Segment Operating Income

2015 - Ingalls operating income in 2015 was $379 million, compared to income of $229 million in 2014. The increase was primarily due to the Aon litigation settlement, the resolution of outstanding contract changes and higher performance on the LHA-6 America-class program, as well as higher performance on the Legend-class NSC program, partially offset by the lower volumes described above.

2014 - Ingalls operating income in 2014 was $229 million, compared to income of $165 million in 2013. The increase was primarily due to performance improvement and risk retirement on the LPD-17 San Antonio-class program and the Legend-class NSC program, as well as the unfavorable impact in the prior year of the Gulfport facility closure, partially offset by the favorable impact in the prior year of hurricane insurance recoveries.

Sales and Service Revenues

2015 - Newport News revenues, including intersegment sales, increased $164 million, or 4%, in 2015 compared to 2014, primarily driven by higher revenues in Submarines and Fleet Support services, partially offset by lower revenues in Aircraft Carriers and Energy services. Submarines revenues related to the SSN-774 Virginia-class submarine program were higher due to higher volumes on Block IV boats, partially offset by lower volumes on Block III boats. Higher revenues in Fleet Support services were primarily due to higher volumes associated with Aircraft Carrier support services. Aircraft Carriers revenues decreased due to lower volumes on the execution contract for the CVN-72 USS Abraham Lincoln RCOH and the construction contract for CVN-78 Gerald R. Ford, partially offset by higher volume on the construction contract for CVN-79 John F. Kennedy. Lower revenues in Energy services were due to lower volumes on environmental remediation programs.

2014 - Newport News revenues, including intersegment sales, increased $154 million, or 4%, in 2014 compared to 2013, primarily driven by the SN3 acquisition, as well as higher revenues in Submarines and Energy, partially offset by lower revenues in Aircraft Carriers and Fleet Support services. Submarines revenues related to the SSN-774 Virginia-class submarine program were higher due to higher volumes on Block IV advance procurement and Block III construction contracts, partially offset by lower volumes on Block II boats following the delivery of SSN-783 USS Minnesota. Higher Energy revenues were primarily driven by higher commercial volumes. Aircraft Carriers revenues decreased due to lower volumes on the execution contract for the CVN-71 USS Theodore Roosevelt RCOH and the construction contract for CVN-78 Gerald R. Ford, partially offset by higher volumes on the execution contract for the CVN-72 USS Abraham Lincoln RCOH and the inactivation contract for CVN-65 USS Enterprise. Lower revenues in Fleet Support services were primarily due to lower volumes associated with repair work on SSN-765 USS Montpelier.

Segment Operating Income

2015 - Newport News operating income in 2015 was $422 million, compared to income of $415 million in 2014. The increase was due to higher volumes and performance on the SSN-774 Virginia-class submarine program and the resolution of outstanding contract changes on the CVN-71 USS Theodore Roosevelt RCOH, partially offset by lower performance on the construction contract for CVN-78 Gerald R. Ford and lower volumes in Aircraft Carriers RCOH programs.

2014 - Newport News operating income in 2014 was $415 million, compared to income of $402 million in 2013. The increase was primarily related to the volume changes discussed above and higher risk retirement on the construction contract for CVN-78 Gerald R. Ford, offset by lower risk retirement on the CVN-71 USS Theodore Roosevelt RCOH.

Sales and Service Revenues

2015 - Revenues in the Other segment for the year ended December 31, 2015, decreased $3 million, or 2%, in 2015 compared to 2014, primarily due to lower volumes in oil and gas services.

2014 - Other revenues in 2014, were $137 million, primarily due to the acquisition of UPI on May 30, 2014.

Segment Operating Income

2015 - Operating loss in the Other segment for the year ended December 31, 2015, was $134 million, compared to an operating loss of $59 million in 2014. The decrease was primarily due to goodwill and intangible asset impairment charges and lower performance in oil and gas services.

2014 - Other operating loss for the year ended December 31, 2014, was $59 million, primarily due to the goodwill impairment charge of $47 million described above.

BACKLOG

Total backlog as of December 31, 2015, was approximately $22 billion. Total backlog includes both funded backlog (firm orders for which funding is contractually obligated by the customer) and unfunded backlog (firm orders for which funding is not currently contractually obligated by the customer). Backlog excludes unexercised contract options and unfunded Indefinite Delivery/Indefinite Quantity orders. For contracts having no stated contract values, backlog includes only the amounts committed by the customer.

We expect approximately 29% of the $22 billion total backlog as of December 31, 2015, to be converted into sales in 2016. U.S. Government orders comprised substantially all of the backlog as of December 31, 2015 and 2014.

Awards

2015 - The value of new contract awards during the year ended December 31, 2015, was approximately $7.6 billion. Significant new awards in 2015 included contracts for detail design and construction for CVN-79 John F. Kennedy, construction of NSC-8 Midgett, continued construction of CVN-78 Gerald R. Ford, and advance planning for the CVN-73 USS George Washington RCOH.

2014 - The value of new contract awards during the year ended December 31, 2014, was approximately $10.1 billion. Significant new awards in 2014 included contracts for Block IV of the SSN-774 Virginia-class submarine program, continued construction preparation for CVN-79 John F. Kennedy, and construction of NSC-7 Kimball.

LIQUIDITY AND CAPITAL RESOURCES

We endeavor to ensure the most efficient conversion of operating results into cash for deployment in operating our businesses and maximizing stockholder value. We use various financial measures to assist in capital deployment decision making, including net cash provided by operating activities and free cash flow. We believe these measures are useful to investors in assessing our financial performance.
