PART I

ITEM 1.    BUSINESS

        Alliant Techsystems Inc. ("ATK" or the "Company") is a premier aerospace and defense company with approximately 19,000 employees and operations in 22 states, Puerto Rico, and internationally.

        ATK was incorporated in Delaware in 1990 when Honeywell Inc. spun off its defense businesses to its stockholders. The spin-off became effective in September 1990, when Honeywell transferred to ATK substantially all of the assets and liabilities of those businesses. Honeywell subsequently distributed to its stockholders in October 1990 all of ATK's outstanding common stock on a pro rata basis. In 1995 we entered the aerospace market with the acquisition of Hercules Aerospace. Since then we have grown to become a leading supplier of aerospace and defense products to the U.S. government, allied nations, and prime contractors. We are also a major supplier of ammunition and related accessories to law enforcement agencies and commercial customers.

        We have grown significantly over the past several years as a result of both internal expansion and a series of acquisitions, including:

•

Thiokol Propulsion in April 2001.

•

The Sporting Equipment Group of Blount International, Inc. in December 2001.

•

The ordnance business of The Boeing Company in May 2002.

•

The assets of Science and Applied Technology, Inc. in October 2002.

•

Composite Optics, Inc. in January 2003.

•

Micro Craft and GASL in November 2003.

•

Mission Research Corporation in March 2004.

•

The PSI Group in September 2004.

•

Swales Aerospace in June 2007.

•

Eagle Industries in March 2009.

        We conduct our business through a number of separate legal entities that are listed in Exhibit 21 to this report. These legal entities are grouped into our operating segments which, as of March 31, 2009, were: ATK Armament Systems, ATK Mission Systems, and ATK Space Systems.

        Sales, income before interest, income taxes and minority interest, total assets, and other financial data for each segment for the three years ended March 31, 2009 are set forth in Note 15 to the consolidated financial statements, included in Item 8 of this report.

        During fiscal 2009, ATK realigned its business operations. As a result of this realignment, ATK combined the Space division of ATK Mission Systems with ATK Launch Systems into a single group now known as ATK Space Systems. Following this realignment, ATK has three segments: ATK Armament Systems, ATK Mission Systems, and ATK Space Systems. The fiscal 2009 realignment is reflected in the information contained in this report and the segment information for prior periods has been restated.

        References in this report to a particular fiscal year refer to the year ended March 31 of that calendar year.

ATK Armament Systems

        ATK Armament Systems develops and produces military ammunition and gun systems; commercial products; tactical accessories and equipment, and propellant and energetics. It also operates the U.S. Army ammunition plants in Independence, Missouri and Radford, Virginia.

Military Ammunition and Gun Systems

        We manufacture a variety of small-caliber training and tactical ammunition rounds at the Lake City Army Ammunition Plant in Independence, Missouri, where production totaled approximately 1.4 billion rounds in fiscal year 2009. The Lake City contract represented approximately 12% of ATK's total fiscal 2009 sales. ATK took over operation of this facility on April 1, 2000 and is responsible for the operation and management, including leasing excess space to third parties in the private sector. ATK has a 10-year production contract to supply the Army's small-caliber ammunition needs that expires April 1, 2010. ATK has reached agreement with the U.S. Army on a four-year supply contract as the primary supplier of small-caliber ammunition to the Department of Defense ("DoD"). Production on the new contract is expected to continue into fiscal 2014. During this same period, ATK will complete government funded projects for modernization of the facility. ATK also has a facilities-use contract for the plant that expires in April 2025. The facilities-use contract expires 11 years after the plant production contract and, if the plant production contract is not renewed, ATK believes the U.S. Army would relieve ATK of all of its obligations under the facilities-use contract. We also conduct small-caliber ammunition research, development, and test activities for the U.S. Army. Current projects include the development of caseless ammunition, and the technology to replace lead in training ammunition with more environmentally friendly materials.

        Medium-caliber ammunition products comprise various families of training and tactical ammunition fired from ground and air combat platforms like the Bradley Fighting Vehicle, Light Armored Vehicle, Apache and Blackhawk helicopters, A-10 close-combat support aircraft, and AC-130 gunship aircraft.

        We develop and manufacture a family of medium-caliber chain-gun systems that provides armament solutions for U.S. and allied combat vehicles, helicopters, and naval vessels. Our gun systems are used on the Bradley Fighting Vehicle, Light Armored Vehicle, Expeditionary Fighting Vehicle, and Apache helicopter. We have supplied more than 15,000 medium-caliber gun systems to the U.S. military and 20 allied nations, including Poland, Finland, Denmark, the Netherlands, Switzerland, Norway, and the Czech Republic. New products include the lightweight 25mm chain gun.

Commercial Products

        We develop and supply ammunition to law enforcement agencies and sport shooting enthusiasts under several different brands, including Federal Premium®, Fusion®, CCI®, Speer®, Blazer® and Estate Cartridge®. Our sport shooting products are distributed through mass merchants and specialty sporting equipment stores and distributors. Law enforcement products are sold to agencies such as the Federal Bureau of Investigation, the Federal Law Enforcement Training Center, and the Department of Homeland Security.

        Our accessory portfolio includes products and equipment for sport shooting enthusiasts who reload their own ammunition; gun care products; targets and traps; rifle scopes and mounts; and binoculars. Our accessories are marketed under a number of different brands, including RCBS®, Outers®, Champion®, Shooter's Ridge®, Weaver®, Redfield®, Simmons®, and Nitrex®, and are distributed through mass merchants and specialty sporting equipment stores and distributors.

Tactical Accessories and Equipment

        We develop and manufacture high-quality, individual operational nylon gear and equipment for military, homeland security, and law enforcement agencies. We manufacture more than 5,000 products which include tactical assault vests, load-bearing equipment, weapon transporting gear, holsters, personal gear carriers, and other high-quality accessories.

Propellant and Energetics

        We develop and manufacture solid extruded propellant for more than 25 types of military ammunition and rocket systems. Major production programs include propellant for medium-caliber and tank ammunition, artillery charge systems, and air and ground launched rockets. We also produce commercial gun powder for sporting ammunition manufacturers and hunters and sport shooters who reload their own ammunition.

        We are also the only North American supplier of military-specification nitrocellulose used in all small, medium, and large-caliber propellant, and rocket motors. We are the only supplier of TNT to the U.S. DoD. This product is used primarily as explosive material for bombs and artillery projectiles. ATK currently has a five-year facilities-use contract to operate the Radford Army ammunition plant. This contract expires on April 1, 2010.

ATK Mission Systems

        ATK Mission Systems operates in two areas: Weapon Systems and Aerospace Systems.

Weapon Systems

        We develop and produce advanced missile systems, precision-guided munitions, force protection systems, soldier weapon systems, barrier systems, and large-caliber direct fires for the U.S. government and its allies. We are also a subcontractor to prime contractors, supplying tactical and hypersonic propulsion systems, warheads, fuzes, and missile defense divert and control systems.

        As a prime contractor, we are developing low-cost, innovative advanced weapon systems that will provide precision and effectiveness for combat forces, artillery batteries, naval gun systems, tanks, and tactical aircraft. Major programs include the Precision Guidance Kit and Advanced Anti-Radiation Guided Missile. We also produce 120mm ammunition for main battle tanks and 105mm ammunition for mobile gun systems.

        Our force protection weapon systems are designed to protect military forces from ground and air threats. Key programs include the Spider combat barrier systems; anti-tank barrier systems; and the Individual High Explosive Air Burst Weapons System.

        As a subcontractor, our work in missile defense primarily includes production of the third-stage motor and the divert and attitude control system for the Standard Missile-3, the interceptor component of the U.S. Navy Aegis Ballistic Missile Defense System.

        We produce rocket motors for tactical weapons fired by aircraft, ships, ground platforms, and combat troops. Major programs include propulsion for the only two U.S. air-to-air missiles in production; the Sidewinder and the Advanced Medium-Range Air-to-Air Missile; propulsion for the Army's surface-to-surface, Non-Line of Sight—Precision Attack Missile; the Hellfire and Maverick air-to-surface missiles; and the Evolved Sea Sparrow surface-to-air missile. We also manufacture warheads for air-to-air and air-to-surface missiles.

        We develop and produce precision fuzes to detonate military munitions, including conventional and precision-guided air-delivered bombs; artillery rounds; medium-caliber ammunition and mortar projectiles; and training hand grenades.

5

        Our STAR™ orbit insertion motors place satellites into orbit, serve as upper stages for launch vehicles, and provide earth escape velocity for spacecraft. Our STAR™ retro/separation motors separate payloads from launch vehicles and decelerate spacecraft as they descend to land on planetary surfaces. We are also developing the Attitude Control Motor for the launch abort system for National Aeronautics and Space Administration's ("NASA") Orion Crew Exploration Vehicle.

Aerospace Systems

        We are a prime contractor on a variety of electronic warfare and aircraft integration programs. We also supply products to other prime contractors, including precision-engineered, low-observable structural components, high-temperature engine components, and high-performance radomes and apertures.

        Our lightweight, high-strength composite structures fly on aircraft, both commercial and military, and space launch vehicles. Commercial aircraft structures include fan containment cases for the General Electric GEnx aircraft engine, aft fan cases for the Rolls Royce Trent XWB engine, and stringers and frames for a new commercial aircraft program. Military aircraft structures include components for the F-22 Raptor, an extensive range of external skins and components for the F-35 Joint Strike Fighter, and various antennae and radomes for multiple aircraft types. Space launch structures fly on commercial rockets used to deploy satellites and on military rockets used for ballistic missile defense, prompt global strike, strategic nuclear deterrence, and satellite launch and deployment. We also provide specialized composite tubes to the United States Enrichment Corporation for use as part of its American Centrifuge Program.

        Electronic warfare products include the AN/AAR-47 Missile Warning System, designed to protect aircraft against surface-to-air and air-to-air missiles and laser-guided and laser-aided threats.

        We are integrating sensor, display, and radar systems on military and commercial aircraft used by the Air National Guard and the Department of Homeland Security. The aircraft perform a variety of missions, including border surveillance, drug enforcement, intelligence gathering, and search and rescue.

ATK Space Systems

        ATK Space Systems operates in two primary businesses: Launch Systems and Spacecraft Systems. The Launch Systems division produces solid rocket motor systems for human and cargo launch vehicles, conventional and strategic missiles, and missile defense interceptors, as well as ordnance decoys and illuminating flares. The Spacecraft Systems division produces small satellites and satellite subsystems and components for large satellites, as well as a variety of other spacecraft.

Launch Systems

        We are the nation's largest provider of solid rocket motors for human space flight, and cargo-carrying launch vehicles. We are the sole manufacturer of the Reusable Solid Rocket Motor ("RSRM") used to launch the NASA's Space Shuttle. In addition, we manufacture the booster separation systems that thrust the motors away from the Shuttle orbiter and the main liquid fuel tank. A set of two RSRMs provides propulsion, in tandem with a liquid propulsion system, for the Space Shuttle. The RSRM uses a metal case and nozzle components that are recovered from the ocean after each flight. The metal cases and nozzle components are then cleaned, refurbished, and manufactured for reuse. The RSRM program represented 9% of ATK's total fiscal 2009 sales.

        In 2006, we were selected by NASA to design, develop, and manufacture the first-stage of the next-generation Ares I Crew Launch Vehicle, which will support future missions to the International Space Station, as well as lunar and Mars missions using the Orion Crew Exploration Vehicle. As the prime contractor for the first-stage, we are responsible for the entire first stage, which includes a new

6

five-segment motor derived from the Space Shuttle's four-segment RSRM. We are also responsible for thrust vector control, stage separation motors, forward and aft interface structures, avionics, ordnance, and parachute recovery systems. The first test flight is scheduled for early fall 2009.

        We are also on a team selected by NASA to build the launch abort system for the Orion Crew Exploration Vehicle, the primary payload for the Ares I vehicle. We are designing, developing, and manufacturing the main separation motor that is located on top of the Orion spacecraft that is designed to pull the crew capsule safely away from the launch vehicle should problems develop during the launch phase. ATK's Mission Systems group is also participating in this effort.

        The five-segment reusable solid rocket motor we are developing for the Ares I Crew Launch Vehicle will also serve as the first-stage propulsion system for the NASA Ares V Cargo Launch Vehicle, the primary heavy lift launch vehicle supporting future missions beyond low earth orbit, to the Moon and beyond. Development activities to support application of the five-segment motor to the Ares V are expected to begin in the 2010 timeframe.

        We manufacture a variety of rocket motor systems for launch vehicles that place payloads into orbit for commercial and government customers. These include motors supporting Boeing Delta launch vehicles; Orion® motors for Orbital Science Corporation Pegasus®, Taurus®, and Minotaur launch vehicles; and CASTOR® motors for Japan's H-IIA rocket and the Orbital Taurus rocket.

        Our Launch Systems division provides most of the solid rocket motors for conventional and strategic missiles. We are refurbishing all three rocket motor stages for the U.S. Air Force silo-based Minuteman III Intercontinental Ballistic Missile under a contract from Northrop Grumman. Full-rate production is scheduled to end in fiscal 2010. We also manufacture rocket motor systems for all three stages of the U.S. Navy submarine-launched Trident II (D5) missile under a contract from Lockheed Martin Space Systems Company. We also recently won a contract to develop the first and third stage rocket motor systems for the Air Force Prompt Global Strike System. The Company does not expect additional revenue from the Kinetic Energy Interceptor program, due to the program's termination in the initial 2010 DoD budget.

        In addition to conventional and strategic missiles, we are a leading provider of propulsion technology for missile defense interceptor missiles. Under a contract from Orbital Sciences Corporation, we supply Orion® rocket motor systems for all three stages of the Ground-based Midcourse Defense system, which is designed to intercept and destroy long-range ballistic missiles during their midcourse phase of flight.

Spacecraft Systems

        We supply responsive spacecraft, components, sub-systems, and technical services to government customers (both classified and unclassified) as well as the large satellite prime contractors for military, civil, and commercial applications.

        We design and produce solar arrays and solar panel substrates that generate power during the life of spacecraft. Major products include the Puma Solar Array for Global Positioning System satellites; and the Ultraflex solar array successfully demonstrated on the Mars Phoenix mission and to be utilized on NASA's Orion Crew Exploration Vehicle (CEV), which will carry astronauts to the International Space Station, as well as to other outposts for space exploration.

        We supply instrument support structures that perform with precision in cryogenic temperatures for civil, military, and classified customers. The structures provide spacecraft telescopes and imaging systems like the James Webb Space Telescope (JWST) and Operational Land Imager (OLI) on the Landsat Data Continuity Mission, the stability required for astronomical observations.

7

        Our titanium propellant tanks for satellites, space launch vehicles, and space exploration vehicles are a critical weight saving component for the majority of domestic and some international satellite missions that have been launched.

        Major composite products include advanced lightweight, high-performance radio frequency antenna reflectors and antennas that enable spacecraft communications. We also produce composite bus structures, towers, and subsystems that house flight systems for satellites. The bus structures are integrated with our thermal control systems and are provided as a complete product to commercial and classified customers. The thermal control systems are also manufactured as stand-alone or customer integrated products enabling a wide variety of missions.

Customers

        Our sales come primarily from contracts with agencies of the U.S. Government and its prime contractors and subcontractors. As the various U.S. Government customers, including the U.S. Army, NASA, the U.S. Air Force, and the U.S. Navy, make independent purchasing decisions, we do not generally regard the U.S. Government as one customer. Instead, we view each agency as a separate customer.

        Fiscal 2009 sales by customer were as follows:

Sales to:			Percent of Sales
	U.S. Army			26	%
	NASA			20	%
	U.S. Air Force			12	%
	U.S. Navy			12	%
	Other U.S. Government customers			6	%
		Total U.S. Government customers		76	%
	Commercial and foreign customers			24	%
		Total		100	%

        Sales to U.S. Government and its prime contractors during the last three fiscal years were as follows:

Fiscal	U.S. Government sales	Percent of sales
2009	$3,486 million		76	%
2008	3,257 million		78	%
2007	2,817 million		79	%

        Our reliance on U.S. Government contracts entails inherent benefits and risks, including those particular to the aerospace and defense industry. We derived approximately 12% of our total fiscal 2009 sales from the military small-caliber ammunition contract at Lake City. No other single contract contributed more than 10% of our sales in fiscal 2009. Our top five contracts accounted for approximately 36% of fiscal 2009 sales.

        The breakdown of our fiscal 2009 sales to the U.S. Government as a prime contractor and a subcontractor was as follows:

Sales as a prime contractor		65	%
Sales as a subcontractor		35	%
	Total	100	%

8

        No single customer, other than the U.S. Government customers listed above, accounted for more than 10% of our fiscal 2009 sales.

        Foreign sales for each of the last three fiscal years are summarized below:

Fiscal	Foreign sales	Percent of sales
2009	$386 million		8.4	%
2008	258 million		6.2	%
2007	247 million		6.9	%

        Sales to foreign governments must be approved by the U.S. DoD and the U.S. State Department or U.S. Commerce Department. Our products are sold directly to U.S. allies as well as through the U.S. Government. Approximately 51% of these sales were in ATK Armament Systems, 37% were in ATK Mission Systems, and 12% were in ATK Space Systems.

        Our major law enforcement customers include large metropolitan police departments, the Department of Homeland Security, the Federal Bureau of Investigation, and the U.S. Secret Service. Major customers of our commercial products business include retailers such as Wal-Mart, Cabela's, and Gander Mountain, as well as large wholesale distributors.

Backlog

        Contracted backlog is the estimated value of contracts for which we are authorized to incur costs and orders have been recorded, but for which revenue has not yet been recognized. The total amount of contracted backlog was approximately $6.5 billion and $6.2 billion as of March 31, 2009 and 2008, respectively. Included in contracted backlog as of March 31, 2009 was $2.4 billion of contracts not yet funded consisting primarily of the Ares I Crew Launch Vehicle, which is discussed above. Approximately 61% of contracted backlog as of March 31, 2009 is not expected to be filled within fiscal 2010.

        Total backlog, which includes contracted backlog plus the value of unexercised options, was approximately $7.0 billion as of March 31, 2009 and $6.5 billion as of March 31, 2008.

Seasonality

        Sales of sporting ammunition have historically been lower in our first fiscal quarter. Our other businesses are not generally seasonal in nature.

Competition

        Our aerospace and defense businesses compete against other U.S. and foreign prime contractors and subcontractors, many of which have substantially more resources to deploy than we do in the pursuit of government and industry contracts. Our ability to compete successfully in this environment depends on a number of factors, including the effectiveness and innovativeness of research and development programs, our ability to offer better program performance than our competitors at a lower cost, our readiness with respect to facilities, equipment, and personnel to undertake the programs for which we compete, and our past performance and demonstrated capabilities. Additional information on the risks related to competition can be found under "Risk Factors" in Item 1A. of this report.

        Our commercial products business competes against manufacturers with well-established brand names and strong market positions. A key strategy in these highly competitive markets is the consistent flow of new and innovative products. We also attempt to control operating costs, particularly for raw materials, since retail consumer purchasing decisions are often driven by price. Enhanced product

9

performance is especially important to our law enforcement customers as they rely on our products to protect and serve the public.

        ATK generally faces competition from a number of competitors in each business area, although no single competitor competes along all of ATK's segments. ATK's principal competitors in each of its segments are as follows:

ATK Armament Systems:    General Dynamics Ordnance and Tactical Systems, Inc., a subsidiary of General Dynamics Corporation; BAE Systems; Winchester Ammunition of Olin Corporation; Remington Arms; and various smaller manufacturers and importers, including Hornady, Black Hills Ammunition, Wolf, Rio Ammunition, Fiocchi Ammunition, and Selliers & Belloitt.

ATK Mission Systems:    Aerojet-General Corporation, a subsidiary of GenCorp Inc.; General Dynamics Corporation; Lockheed Martin Corporation; Raytheon Company; Textron Inc.; Pratt & Whitney Space and Missile Propulsion of United Technologies Corporation; The Boeing Company; L-3 Communications Corporation; Northrop Grumman Corporation; GKN plc; AAR Corp.; Vought Aircraft Industries, Inc.; Goodrich Corporation; Applied Aerospace Structures Corporation; Science Applications International Corporation (SAIC); Ball Aerospace & Technologies Corporation, a subsidiary of Ball Corporation; and Georgia University of Technology.

ATK Space Systems:    Aerojet-General Corporation, a subsidiary of GenCorp Inc.; Kilgore Flares Company, LLC, a subsidiary of Chemring Group, PLC; Pratt & Whitney Rocketdyne, Inc., a subsidiary of United Technologies Corporation; Orbital Sciences Corporation; Ball Aerospace & Technologies Corporation; General Dynamics-Integrated Space Systems; Sierra Nevada Corporation; AASC; and Keystone & ARDE of United Technologies.

Research and Development

        We conduct extensive research and development ("R&D") activities. Company-funded R&D is primarily for the development of next-generation technology. Customer-funded R&D is comprised primarily of activities we conduct under contracts with the U.S. Government and its prime contractors. R&D expenditures in each of the last three fiscal years were as follows:

Fiscal	Company-funded Research and Development	Customer-funded Research and Development
2009	$81.5 million	$865.5 million
2008	68.3 million	785.7 million
2007	61.5 million	596.6 million

Raw Materials

        We use a broad range of raw materials in manufacturing our products, including aluminum, steel, copper, lead, graphite fiber, cotton linters, and epoxy resins and adhesives. We monitor the sources from which we purchase these materials in an attempt to ensure there are adequate supplies to support our operations. We also monitor the prices of materials, particularly commodity metals like copper, which have fluctuated dramatically over the past several years.

        We procure these materials from a variety of sources. In the case of our government contracts, we are often required to purchase from sources approved by the U.S. DoD. When these suppliers or others choose to eliminate certain materials we require from their product offering, we attempt to qualify other suppliers or replacement materials to ensure there are no disruptions to our operations. Additional information on the risks related to raw materials can be found under "Risk Factors" in Item 1A. of this report.

10

Intellectual Property

        As of March 31, 2009, we owned 424 U.S. patents and 326 foreign patents. We also had approximately 165 U.S. patent applications and approximately 160 foreign patent applications pending.

        Although we manufacture various products covered by patents, we do not believe that any single existing patent, license, or group of patents is material to our success. We believe that unpatented research, development, and engineering skills also make an important contribution to our business. The U.S. Government typically receives royalty-free licenses to inventions made under U.S. Government contracts. Consistent with our policy to protect proprietary information from unauthorized disclosure, we ordinarily require employees to sign confidentiality agreements as a condition of employment.

        As many of our products are complex and involve patented and other proprietary technologies, we face a risk of claims that we have infringed upon third-party intellectual property rights. Such claims could result in costly and time-consuming litigation, the invalidation of intellectual property rights, or increased licensing costs.

Regulatory Matters

U.S. Governmental Contracts

        We are subject to the procurement policies and procedures set forth in the Federal Acquisition Regulation ("FAR"). The FAR governs all aspects of government contracting, including competition and acquisition planning; contracting methods and contract types; contractor qualifications; and acquisition procedures. Every government contract contains a list of FAR provisions that must be complied with in order for the contract to be awarded. The FAR provides for regular audits and reviews of contract procurement, performance, and administration. Failure to comply with the provisions of the FAR could result in contract termination.

        The U.S. Government may terminate its contracts with its suppliers, either for convenience or in the event of a default as a result of our failure to perform under the applicable contract. If a cost-plus contract is terminated for convenience, we are entitled to reimbursement of our approved costs and payment of a total fee proportionate to the percentage of the work completed under the contract. If a fixed-price contract is terminated for convenience, we are entitled to payment for items delivered to and accepted by the U.S. Government and fair compensation for work performed plus the costs of settling and paying claims by terminated subcontractors, other settlement expenses, and a reasonable profit on the costs incurred or committed. If a contract termination is for default, we are paid an amount agreed upon for completed and partially completed products and services accepted by the U.S. Government and may be liable to the U.S. Government for repayment of any advance payments and progress payments related to the terminated portions of the contract, as well as excess costs incurred by the U.S. Government in procuring undelivered items from another source.

ITEM 1A.    RISK FACTORS

        ATK is subject to a number of risks, including those related to being a U.S. Government contractor. Some of the risks facing ATK are discussed below.

13

ATK's business could be adversely impacted by reductions or changes in NASA or U.S. Government military spending.

        As the majority of ATK's sales are to the U.S. Government and its prime contractors, ATK depends heavily on the contracts underlying these programs. Significant portions of ATK's sales come from a small number of contracts. ATK's top five contracts, all of which are contracts with the U.S. Government, accounted for approximately 36% of fiscal 2009 sales. ATK's military small-caliber ammunition contract contributed approximately 12% of total fiscal 2009 sales. The loss or significant reduction of a material program in which ATK participates could have a material adverse effect on ATK's operating results, financial condition, or cash flows.

        ATK's small-caliber ammunition operations for the U.S. military and U.S. allies are conducted at the Lake City Army Ammunition Plant (Lake City) in Independence, Missouri. Lake City is the Army's principal small-caliber ammunition production facility and is the primary supplier of the U.S. military's small-caliber ammunition needs. ATK took over operation of this facility on April 1, 2000 and is responsible for the operation and management, including leasing excess space to third parties in the private sector. ATK has a 10-year production contract to supply the Army's small-caliber ammunition needs that expires April 1, 2010. ATK has reached agreement with the U.S. Army on a four-year supply contract as the primary supplier of small-caliber ammunition to the U.S. DoD for both its training and tactical needs. Production on the new contract is expected to continue into fiscal 2014. During this same period, ATK will complete government funded projects for modernization of the facility. ATK also has a facilities-use contract for the plant that expires in April 2025. Although the facilities-use contract expires 11 years after the plant production contract, if the plant production contract is not renewed, ATK believes the U.S. Army would relieve ATK of all of its obligations under the facilities-use contract. Future ATK production under this contract or levels of government spending cannot be predicted with certainty.

        In 2006, ATK was chosen by NASA to design, develop, and manufacture the first-stage for the next-generation Ares I Crew Launch Vehicle, which will replace the Space Shuttle launch system scheduled for retirement from service as early as 2010. As the prime contractor for the first-stage, in addition to a new five-segment motor derived from the Space Shuttle's four-segment Reusable Solid Rocket Motor ("RSRM"), ATK is also responsible for thrust vector control, stage separation motors, forward and aft interface structures, ordnance, and parachute recovery systems. The first test flight is scheduled for fiscal 2010. ATK believes that its RSRM products used on the Space Shuttle and the Ares I Crew Launch Vehicle will be important to achieving affordable launch systems for NASA. On May 7, 2009, NASA announced its intention to conduct an independent review of its human space flight plans, including alternatives to current plans. The study's results will support the Administration's decision on how to proceed with the development of a next-generation launch vehicle for human space flight. If NASA reduces its budget, changes its development plan, or delays test flights, or if ATK is unable to provide its Ares components on time, there could be an adverse effect on ATK's operating results, financial condition, or cash flows.

        U.S. Government contracts are also dependent on the continuing availability of Congressional appropriations. Congress usually appropriates funds for a given program on a fiscal year basis even though contract performance may take more than one year. As a result, at the outset of a major program, the contract is usually incrementally funded, and additional monies are normally committed to the contract by the procuring agency only as Congress makes appropriations for future fiscal years. In addition, most U.S. Government contracts are subject to modification if funding is changed. Any failure by Congress to appropriate additional funds to any program in which ATK participates, or any contract modification as a result of funding changes, could materially delay or terminate the program. This could have a material adverse effect on ATK's operating results, financial condition, or cash flows.

14

ATK may not be able to react to increases in its costs due to the nature of its U.S. Government contracts.

        ATK's U.S. Government contracts can be categorized as either "cost-plus" or "fixed-price."

        Cost-Plus Contracts.    Cost-plus contracts are cost-plus-fixed-fee, cost-plus-incentive-fee, or cost-plus-award-fee contracts. Cost-plus-fixed-fee contracts allow ATK to recover its approved costs plus a fixed fee. Cost-plus-incentive-fee contracts and cost-plus-award-fee contracts allow ATK to recover its approved costs plus a fee that can fluctuate based on actual results as compared to contractual targets for factors such as cost, quality, schedule, and performance. The award or incentive fees that are typically associated with these programs are subject to uncertainty and may be earned over extended periods. In these cases, the associated financial risks are primarily in lower profit rates or program cancellation if cost, schedule, or technical performance issues arise.

        Fixed-Price Contracts.    Fixed-price contracts are firm-fixed-price, fixed-price-incentive, or fixed-price-level-of-effort contracts. Under firm-fixed-price contracts, ATK agrees to perform certain work for a fixed price and absorb any cost underruns or overruns. Fixed-price-incentive contracts are fixed-price contracts under which the final contract prices may be adjusted based on total final costs compared to total target cost, and may be affected by schedule and performance. Fixed-price-level-of-effort contracts allow for a fixed price per labor hour, subject to a contract cap. All fixed-price contracts present the inherent risk of unreimbursed cost overruns. If the initial estimates used to calculate the contract price and the cost to perform the work prove to be incorrect, there could be a material adverse effect on operating results, financial condition, or cash flows. In addition, some contracts have specific provisions relating to cost, schedule, and performance. If ATK fails to meet the terms specified in those contracts, the cost to perform the work could increase or ATK's price could be reduced, which would adversely affect the Company's financial condition. The U.S. Government also regulates the accounting methods under which costs are allocated to U.S. Government contracts.

        The following table summarizes how much each of these types of contracts contributed to ATK's U.S. Government business in fiscal 2009:

Cost-plus contracts:
	Cost-plus-fixed-fee		16	%
	Cost-plus-incentive-fee/cost-plus-award-fee		37	%
Fixed-price contracts:
	Firm-fixed-price		47	%
		Total	100	%

ATK's U.S. Government contracts are subject to termination.

        ATK is subject to the risk that the U.S. Government may terminate its contracts with its suppliers, either for convenience or in the event of a default by the contractor. If a cost-plus contract is terminated, the contractor is entitled to reimbursement of its approved costs. If the contractor would have incurred a loss had the entire contract been performed, then no profit is allowed by the U.S. Government. If the termination is for convenience, the contractor is also entitled to receive payment of a total fee proportionate to the percentage of the work completed under the contract. If a fixed-price contract is terminated, the contractor is entitled to receive payment for items delivered to and accepted by the U.S. Government. If the termination is for convenience, the contractor is also entitled to receive fair compensation for work performed plus the costs of settling and paying claims by terminated subcontractors, other settlement expenses, and a reasonable profit on the costs incurred or committed. If a contract termination is for default:

•

the contractor is paid an amount agreed upon for completed and partially completed products and services accepted by the U.S. Government,

15

•

the U.S. Government is not liable for the contractor's costs for unaccepted items, and is entitled to repayment of any advance payments and progress payments related to the terminated portions of the contract, and

•

the contractor may be liable for excess costs incurred by the U.S. Government in procuring undelivered items from another source.

ATK is subject to procurement and other related laws and regulations, non-compliance with which may expose ATK to adverse consequences.

        ATK is subject to extensive and complex U.S. Government procurement laws and regulations, along with ongoing U.S. Government audits and reviews of contract procurement, performance, and administration. ATK could suffer adverse consequences if it were to fail to comply, even inadvertently, with these laws and regulations or with laws governing the export of munitions and other controlled products and commodities; or commit a significant violation of any other federal law. These consequences could include contract termination; civil and criminal penalties; and, under certain circumstances, ATK's suspension and debarment from future U.S. Government contracts for a period of time. In addition, foreign sales are subject to greater variability and risk than ATK's domestic sales. Foreign sales subject ATK to numerous stringent U.S. and foreign laws and regulations, including regulations relating to import-export control, exchange controls, the Foreign Corrupt Practices Act, and the anti-boycott provisions of the U.S. Export Administration Act. Failure to comply with these laws and regulations could result in material adverse consequences to ATK.

Novation of U.S. Government contracts involves risk.

        When U.S. Government contracts are transferred from one contractor to another, such as in connection with the sale of a business, the U.S. Government may require that the parties enter into a novation agreement. A novation agreement generally provides that:

•

the transferring contractor guarantees or otherwise assumes liability for the performance of the acquiring contractor's obligations under the contract,

•

the acquiring contractor assumes all obligations under the contract, and

•

the U.S. Government recognizes the transfer of the contract and related assets.

Other risks associated with U.S. Government contracts may expose ATK to adverse consequences.

        In addition, like all U.S. Government contractors, ATK is subject to risks associated with uncertain cost factors related to:

•

scarce technological skills and components,

•

the frequent need to bid on programs in advance of design completion, which may result in unforeseen technological difficulties and/or cost overruns,

•

the substantial time and effort required for design and development,

•

design complexity,

•

rapid obsolescence, and

•

the potential need for design improvement.

ATK uses estimates in accounting for its programs. Changes in estimates could affect ATK's financial results.

        Contract accounting requires judgment relative to assessing risks, estimating contract revenues and costs, and making assumptions for schedule and technical issues. Due to the size and nature of many of

16

ATK's contracts, the estimation of total revenues and cost at completion is complex and subject to many variables. Assumptions are made regarding the length of time to complete the contract because costs also include expected increases in wages and prices for materials. Similarly, assumptions are made regarding the future impacts of efficiency initiatives and cost reduction efforts. Incentives or penalties related to performance on contracts are considered in estimating revenue and profit rates, and are recorded when there is sufficient information to assess anticipated performance. Estimates of award and incentive fees are also used in estimating revenue and profit rates based on actual and anticipated awards.

        Because of the significance of the judgments and estimation processes described above, it is likely that materially different amounts could be recorded if ATK used different assumptions or if the underlying circumstances were to change. Changes in underlying assumptions, circumstances or estimates may adversely affect future period financial performance. Additional information on ATK's accounting policies for revenue recognition can be found under "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the section titled "Critical Accounting Policies" in Item 7 of this report.

ATK has a substantial amount of debt, and the cost of servicing that debt could adversely affect ATK's business and hinder ATK's ability to make payments on its debt.

        As of March 31, 2009, ATK had total debt of $1.5 billion. In addition, ATK had $153.6 million of outstanding but undrawn letters of credit and, taking into account these letters of credit, an additional $346.4 million of availability under its revolving credit facility. Additional information on ATK's debt can be found under "Liquidity and Capital Resources" in Item 7 of this report.

        ATK has demands on its cash resources in addition to interest and principal payments on its debt including, among others, operating expenses. ATK's level of indebtedness and these significant demands on ATK's cash resources could:

•

make it more difficult for ATK to satisfy its obligations,

•

require ATK to dedicate a substantial portion of its cash flow from operations to payments on its debt, thereby reducing the amount of cash flow available for working capital, capital expenditures, acquisitions, share repurchases, and other general corporate purposes,

•

limit ATK's flexibility in planning for, or reacting to, changes in the defense and aerospace industries,

•

place ATK at a competitive disadvantage compared to competitors that have lower debt service obligations and significantly greater operating and financing flexibility,

•

limit, along with the financial and other restrictive covenants applicable to ATK's indebtedness, among other things, ATK's ability to borrow additional funds,

•

increase ATK's vulnerability to general adverse economic and industry conditions, and

•

result in a default event upon a failure to comply with financial covenants contained in ATK's senior credit facilities which, if not cured or waived, could have a material adverse effect on ATK's business, financial condition, or results of operations.

        ATK's ability to pay interest on and repay its long-term debt and to satisfy its other liabilities will depend upon future operating performance and ATK's ability to refinance its debt as it becomes due. ATK's future operating performance and ability to refinance will be affected by prevailing economic conditions at that time and financial, business and other factors, many of which are beyond ATK's control.

17

        If ATK is unable to service its indebtedness and fund operating costs, ATK will be forced to adopt alternative strategies that may include:

•

reducing or delaying expenditures for capital equipment and/or share repurchases,

•

seeking additional debt financing or equity capital,

•

selling assets, or

•

restructuring or refinancing debt.

        There can be no assurance that any such strategies could be implemented on satisfactory terms, if at all.

ATK is subject to intense competition and therefore may not be able to compete successfully.

        ATK encounters competition for most contracts and programs. Some of these competitors have substantially greater financial, technical, marketing, manufacturing, distribution, and other resources. ATK's ability to compete for these contracts depends to a large extent upon:

•

its effectiveness and innovativeness of research and development programs,

•

its ability to offer better program performance at a lower cost than the competitors,

•

its readiness with respect to facilities, equipment, and personnel to undertake the programs for which it competes, and

•

its past performance and demonstrated capabilities.

        In some instances, the U.S. Government directs a program to a single supplier. In these cases, there may be other suppliers who have the capability to compete for the programs involved, but they can only enter or reenter the market if the U.S. Government chooses to open the particular program to competition. ATK's sole-source contracts accounted for 52% of U.S. Government sales in fiscal 2009 and include the following programs: RSRM Space Shuttle boosters, Ares I first stage, Kinetic Energy Interceptor, Trident II missiles, Minuteman III Propulsion Replacement Program, Advanced Medium-Range Air-to-Air Missile, Hellfire, Sensor Fuzed Weapon propulsion systems, M830A1 multi-purpose tank ammunition rounds, M829A3 tank ammunition, Mk-90 propellant grains for the Hydra 70 and APKWS unguided and guided applications, M789 Lightweight 30 High Explosive Dual Purpose and M792 25mm High Explosive Incendiary—Traced with Self Destructing Fuze for medium-caliber ammunition, the AAR-47 missile warning system, Javelin launch tubes, Solid Divert and Attitude Control Systems and Third Stage Rocket Motors, STAR™ Motors, the American Centrifuge Program, Advanced Anti-Radiation Guided Missile ("AARGM"), Mobile Ground-to-Air Radar Jamming System, Spider barrier system, and the XM-8/XM-25 Family of Gun Systems.

        In the commercial ammunition and accessories markets, ATK competes against manufacturers that have well-established brand names and strong market positions. ATK has seen a spike in demand for commercial ammunition. Should this demand decrease, there may be an adverse effect on the results of operations within ATK Armament Systems.

        The downsizing of the munitions industrial base has resulted in a reduction in the number of competitors through consolidations and departures from the industry. This has reduced the number of competitors for some contracts and programs, but has strengthened the capabilities of some of the remaining competitors. In addition, it is possible that there will be increasing competition from the remaining competitors in business areas where they do not currently compete, particularly in those business areas dealing with electronics.

18

Failure of ATK's subcontractors to perform their contractual obligations could materially and adversely impact ATK's prime contract performance and ability to obtain future business.

        ATK relies on subcontracts with other companies to perform a portion of the services ATK provides its customers on many of its contracts. There is a risk that ATK may have disputes with its subcontractors, including disputes regarding the quality and timeliness of work performed by the subcontractor, customer concerns about the subcontract, ATK's failure to extend existing task orders or issue new task orders under a subcontract, or ATK's hiring of personnel of a subcontractor. A failure by one or more of ATK's subcontractors to satisfactorily provide on a timely basis the agreed-upon supplies or perform the agreed-upon services may materially and adversely impact ATK's ability to perform its obligations as the prime contractor. Subcontractor performance deficiencies could result in a customer terminating a contract for default. A default termination could expose ATK to liability and have a material adverse effect on the ability to compete for future contracts and orders.

Disruptions in the supply of key raw materials and difficulties in the supplier qualification process, as well as increases in prices of raw materials, could adversely impact ATK.

        Key raw materials used in ATK's operations include aluminum, steel, steel alloys, copper, zinc, lead, graphite fiber, prepreg, hydroxy terminated polybutadiene, epoxy resins and adhesives, ethylene propylene diene monomer rubbers, cotton fiber, wood pulp cellulose, diethylether, x-ray film, plasticizers and nitrate esters, impregnated ablative materials, various natural and synthetic rubber compounds, polybutadiene, acrylonitrile, and ammonium perchlorate. ATK also purchases chemicals; electronic, electro-mechanical and mechanical components; subassemblies; and subsystems that are integrated with the manufactured parts for final assembly into finished products and systems.

        ATK monitors sources of supply to attempt to assure that adequate raw materials and other supplies needed in manufacturing processes are available. As a U.S. Government contractor, ATK is frequently limited to procuring materials and components from sources of supply approved by the U.S. DoD. In addition, as business conditions, the DoD budget, and Congressional allocations change, suppliers of specialty chemicals and materials sometimes consider dropping low volume items from their product lines, which may require, as it has in the past, qualification of new suppliers for raw materials on key programs. The supply of ammonium perchlorate, a principal raw material used in ATK's operations, is limited to a single source that supplies the entire domestic solid propellant industry. This single source, however, maintains two separate manufacturing lines a reasonable distance apart, which mitigates the likelihood of a fire, explosion, or other problem impacting all production. ATK may also rely on one primary supplier for other production materials. Although other suppliers of the same materials may exist, the addition of a new supplier may require ATK to qualify the new source for use. The qualification process may impact ATK's profitability or ability to meet contract deliveries.

        Certain suppliers of materials used in the manufacturing of rocket motors have discontinued the production of some materials. These materials include certain insulation and resin materials for rocket motor cases and aerospace-grade rayon for nozzles. ATK has qualified new replacement materials for some programs. For other programs, ATK or ATK's customer has procured sufficient inventory to cover current program requirements and is in the process of qualifying new replacement materials to be qualified in time to meet future production needs. ATK's profitability may be affected if unforeseen difficulties in developing and qualifying replacement materials occur.

        ATK is also impacted by increases in the prices of raw materials used in production on commercial and fixed-price business. ATK has seen a significant fluctuation in the prices of commodity metals, including copper, lead, steel, and zinc. The fluctuating costs of natural gas and electricity also have an impact on the cost of operating ATK's factories.

        Prolonged disruptions in the supply of any of ATK's key raw materials, difficulty completing qualification of new sources of supply, implementing use of replacement materials or new sources of

19

supply, or a continuing increase in the prices of raw materials and energy could have a material adverse effect on ATK's operating results, financial condition, or cash flows.

ATK's future success will depend, in part, on its ability to develop new technologies and maintain a qualified workforce to meet the needs of its customers.

        Virtually all of the products produced and sold by ATK are highly engineered and require sophisticated manufacturing and system integration techniques and capabilities. Both the commercial and government markets in which the company operates are characterized by rapidly changing technologies. The product and program needs of ATK's government and commercial customers change and evolve regularly. Accordingly, ATK's future performance in part depends on its ability to identify emerging technological trends, develop and manufacture competitive products, and bring those products to market quickly at cost-effective prices. In addition, because of the highly specialized nature of its business, ATK must be able to hire and retain the skilled and appropriately qualified personnel necessary to perform the services required by its customers. ATK's operating results, financial condition, or cash flows may be adversely affected if it is unable to develop new products that meet customers' changing needs or successfully attract and retain qualified personnel.

Due to the volatile and flammable nature of its products, fires or explosions may disrupt ATK's business.

        Many of ATK's products involve the manufacture and/or handling of a variety of explosive and flammable materials. From time to time, these activities have resulted in incidents which have temporarily shut down or otherwise disrupted some manufacturing processes, causing production delays and resulting in liability for workplace injuries and fatalities. ATK has safety and loss prevention programs which require detailed pre-construction reviews of process changes and new operations, along with routine safety audits of operations involving explosive materials, to mitigate such incidents, as well as a variety of insurance policies. However, ATK cannot ensure that it will not experience similar incidents in the future or that any similar incidents will not result in production delays or otherwise have a material adverse effect on its results of operations, financial condition, or cash flows.

ATK is subject to environmental laws and regulations that govern both past practices and current compliance which may expose ATK to adverse consequences.

        ATK's operations and ownership or use of real property are subject to a number of federal, state, and local environmental laws and regulations, including those for discharge of hazardous materials, remediation of contaminated sites, and restoration of damage to the environment. At certain sites that ATK owns or operates or formerly owned or operated, there is known or potential contamination that ATK is required to investigate, remediate, or provide resource restoration. ATK could incur substantial costs, including remediation costs, resource restoration costs, fines, and penalties, or third party property damage or personal injury claims, as a result of liabilities associated with past practices or violations of environmental laws or non-compliance with environmental permits.

        ATK expects that a portion of its environmental compliance and remediation costs will be recoverable under U.S. Government contracts. Some of the remediation costs that are not recoverable from the U.S. Government that are associated with facilities purchased in a business acquisition may be covered by various indemnification agreements, as described below.

•

As part of its acquisition of the Hercules Aerospace Company in fiscal 1995, ATK assumed responsibility for environmental compliance at the facilities acquired from Hercules (the "Hercules Facilities"). ATK believes that a portion of the compliance and remediation costs associated with the Hercules Facilities will be recoverable under U.S. Government contracts, and that those environmental remediation costs not recoverable under these contracts will be covered by Hercules Incorporated, a subsidiary of Ashland Inc., ("Hercules") under environmental agreements entered into in connection with the Hercules acquisition. Under these agreements, Hercules has agreed to indemnify ATK for environmental conditions relating to releases or

20

hazardous waste activities occurring prior to ATK's purchase of the Hercules Facilities; fines relating to pre-acquisition environmental compliance; and environmental claims arising out of breaches of Hercules' representations and warranties. Hercules is not required to indemnify ATK for any individual claims below $50,000. Hercules is obligated to indemnify ATK for the lowest cost response of remediation required at the facility that is acceptable to the applicable regulatory agencies. ATK is not responsible for conducting any remedial activities with respect to the Kenvil, NJ facility or the Clearwater, FL facility. In accordance with its agreement with Hercules, ATK notified Hercules of all known contamination on non-federal lands on or before March 31, 2000, and on federal lands on or before March 31, 2005.

•

ATK generally assumed responsibility for environmental compliance at the Thiokol Facilities acquired from Alcoa Inc. ("Alcoa") in fiscal 2002. While ATK expects that a portion of the compliance and remediation costs associated with the acquired Thiokol Facilities will be recoverable under U.S. Government contracts, ATK has recorded an accrual to cover those environmental remediation costs at these facilities that will not be recovered through U.S. Government contracts. In accordance with its agreement with Alcoa, ATK notified Alcoa of all known environmental remediation issues as of January 30, 2004. Of these known issues, ATK is responsible for any costs not recovered through U.S. Government contracts at Thiokol Facilities up to $29 million, ATK and Alcoa have agreed to split evenly any amounts between $29 million and $49 million, and ATK is responsible for any payments in excess of $49 million.

With respect to the commercial products business' facilities purchased from Blount in fiscal 2002, Blount has agreed to indemnify ATK for certain compliance and remediation liabilities, to the extent those liabilities are related to pre-closing environmental conditions at or related to these facilities. Some other remediation costs are expected to be paid directly by a third party pursuant to an existing indemnification agreement with Blount. Blount's indemnification obligations relating to environmental matters, which extended through December 7, 2006, are capped at $30 million, less any other indemnification payments made for breaches of representations and warranties. The third party's obligations, which extended through November 4, 2007, are capped at approximately $125 million, less payments previously made.

        ATK cannot ensure that the U.S. Government, Hercules, Alcoa, Blount, or other third parties will reimburse it for any particular environmental costs or reimburse ATK in a timely manner or that any claims for indemnification will not be disputed. U.S. Government reimbursements for cleanups are financed out of a particular agency's operating budget and the ability of a particular governmental agency to make timely reimbursements for cleanup costs will be subject to national budgetary constraints. ATK's failure to obtain full or timely reimbursement from the U.S. Government, Hercules, Alcoa, Blount, or other third parties could have a material adverse effect on its operating results, financial condition, or cash flows.

        In December 2001, ATK received notice from the State of Utah of a potential claim against ATK under Section 107(f) of the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") for natural resource damages at Bacchus, one of the Hercules Facilities, in Magna, Utah. The notice letter, which was issued to preserve the State's rights under CERCLA, also expressly acknowledged the State's willingness to allow ATK to go forward with its currently-planned monitoring and remediation program. The State's preliminary estimate of damages contained in this claim was $139 million, which is based on known and alleged groundwater contamination at and near Bacchus and is related to Hercules' manufacturing operations at the site. ATK has had discussions with the State regarding this claim and entered into a tolling agreement with the State in fiscal 2002. In fiscal 2003, ATK entered into a similar tolling agreement with the State regarding the Promontory facility that was acquired from Alcoa in the acquisition of Thiokol. These agreements effectively defer the bringing of any potential claim against ATK by the State for a period of at least 10 years. These agreements allow ATK time to continue to identify and address the contamination by the normal and planned regulatory remediation processes in Utah. Although ATK has previously made accruals for its

21

best estimate of the probable and reasonably estimable costs related to the remediation obligations known to ATK with respect to the affected areas, ATK cannot yet predict if or when a suit may be filed against it, nor can ATK determine any additional costs that may be incurred in connection with this matter.

        While ATK has environmental management programs in place to mitigate risks, environmental laws and regulations have not had a material adverse effect on ATK's operating results, financial condition, or cash flows in the past, and it is difficult to predict whether they will have a material impact in the future.

The level of returns on pension and postretirement plan assets, changes in interest rates and other factors could affect ATK's earnings and cash flows.

        ATK's earnings may be positively or negatively impacted by the amount of expense or income recorded for employee benefit plans, primarily pension plans and other postretirement plans. Generally accepted accounting principles ("GAAP") in the United States of America require ATK to calculate income or expense for the plans using actuarial valuations. These valuations are based on assumptions made relating to financial market and other economic conditions. Changes in key economic indicators can result in changes in these assumptions. The key year-end assumptions used to estimate pension and postretirement benefit expense or income for the following year are the discount rate, the expected long-term rate of return on plan assets, the rate of increase in future compensation levels, mortality rates, and the health care cost trend rate. ATK is required to remeasure its plan assets and benefit obligations annually, which may result in a significant change to stockholders' equity through other comprehensive income (loss). ATK's pension and other postretirement benefit income or expense can also be affected by legislation or other regulatory actions. Additional information on how ATK's financial statements can be affected by pension plan accounting policies can be found under "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the section titled "Critical Accounting Policies" in Item 7 of this report.

Capital market volatility could adversely impact ATK's earnings because of ATK's capital structure.

        As of March 31, 2009, there was a total of $779 million of ATK's convertible senior subordinated notes outstanding, subject to the terms of various indentures. The indentures require ATK to satisfy up to the principal amount of these notes solely in cash. In addition, the indentures require ATK to pay any additional amounts above the principal amount of the notes in cash, common stock, or a combination of cash and common stock at ATK's discretion. Holders of ATK's $280 million aggregate principal amount of 2.75% Convertible Senior Subordinated Notes may require ATK to repurchase in cash some or all of these notes in August 2009. As the price of ATK's common stock increases above the conversion price of the notes, ATK includes the dilutive impact of the number of shares that would be issued if converted, which decreases earnings per share.

        ATK is also exposed to the risk of fluctuation in interest rates. If interest rates increase, ATK may incur increased interest expense on variable interest-rate debt or short-term borrowings, which could have an adverse impact on ATK's operating results and cash flows.

ATK is exposed to risks associated with diversification into new markets.

        ATK's long-term business growth strategy includes diversification into new markets such as commercial aerospace structures. Such efforts involve a number of risks, including increased capital expenditures, market uncertainties, schedule delays, extended payment terms, diversion of management attention, additional credit risk associated with new customers, and costs incurred in competing with companies with strong brand names and market positions. An unfavorable event or trend in any one or more of these factors could adversely affect ATK's operating results, financial condition, or cash flows.

22

Financial market disruptions or volatility in the United States and elsewhere may impact ATK's customers and vendors and create challenges that could have a material adverse effect on ATK's business and results of operations.

        Recent economic turmoil, including the failure of financial service companies and the related liquidity crisis has caused significant volatility within the capital and credit markets. This disruption has resulted in decreased economic activity and increased economic uncertainty. As a result, ATK's commercial customers' ability to make timely payments may be adversely impacted and there may be an increase in customer and vendor bankruptcies. A prolonged recession could result in a decline in demand within the commercial sector, which may adversely affect ATK's operating results, financial condition, or cash flows.

International sales are subject to greater risks that sometimes are associated with doing business in foreign countries.

        ATK's international business may pose greater risks than its business in the United States because in some countries there is increased potential for changes in economic, legal and political environments. ATK's international business is also sensitive to changes in a foreign government's national priorities and budgets. International transactions frequently involve increased financial and legal risks arising from foreign exchange rate variability and differing legal systems and customs in other countries. In addition, some international customers require contractors to agree to offset programs that may require in-country purchases or manufacturing or financial support arrangements as a condition to awarding contracts. The contracts may include penalties in the event the company fails to perform in accordance with the offset requirements. An unfavorable event or trend in any one or more of these factors could adversely affect ATK's operating results, financial condition, or cash flows.

ATK may pursue or complete acquisitions which represent additional risk and could impact future financial results.

        ATK's business strategy includes the potential for future acquisitions. Acquisitions involve a number of risks including integration of the acquired company with ATK's operations and unanticipated liabilities or contingencies related to the acquired company. ATK cannot ensure that the expected benefits of any future acquisitions will be realized. Costs could be incurred on pursuits or proposed acquisitions that have not yet or may not close which could significantly impact ATK's operating results, financial condition, or cash flows. Additionally, after the acquisition, unforeseen issues could arise which adversely affect the anticipated returns or which are otherwise not recoverable as an adjustment to the purchase price. Even after careful integration efforts, actual operating results may vary significantly from initial estimates. Goodwill accounts for approximately $1.2 billion of ATK's recorded total assets. ATK evaluates goodwill for impairment annually, or when evidence of potential impairment exists. The annual impairment test is based on several factors requiring judgment. Principally, a significant decrease in expected cash flows or changes in market conditions may indicate potential impairment of recorded goodwill. Changes in future estimated cash flows, the substantial reduction in the market multiples, and the implied valuation of this and comparable companies led to a non-cash charge of $108.5 million for impairment of goodwill in ATK's Spacecraft Systems division in fiscal 2009. If the current economic conditions continue to deteriorate causing further decline in ATK's stock price, additional impairments to one or more businesses could occur in future periods whether or not connected to ATK's annual impairment analysis. ATK will continue to monitor the recoverability of the carrying value of its goodwill and other long-lived assets.

23

ATK's profitability could be impacted by unanticipated changes in its tax provisions or exposure to additional income tax liabilities.

        ATK's business operates in many locations under government jurisdictions that impose income taxes. Changes in domestic or foreign income tax laws and regulations, or their interpretation, could result in higher or lower income tax rates assessed or changes in the taxability of certain revenues or the deductibility of certain expenses, thereby affecting income tax expense and profitability. In addition, audits by income tax authorities could result in unanticipated increases in income tax expense.

        There are no unresolved staff comments as of the date of this report.

ITEM 2.    PROPERTIES

        Facilities.    As of March 31, 2009, ATK occupied manufacturing, assembly, warehouse, test, research, development, and office facilities having a total floor space of approximately 20 million square feet. These facilities are either owned or leased, or are occupied under facilities-use contracts with the U.S. Government.

        As of March 31, 2009, ATK's operating segments had significant operations at the following locations:

ATK Armament Systems	Mesa, AZ; Oroville, CA; Santo Domingo, Dominican Republic; Lewiston, ID; Anoka, MN; Independence, MO; Fenton, MO; New Bedford, MA; Lares, Puerto Rico; Mayaguez, Puerto Rico; Radford, VA; Onalaska, WI

(1)

These facilities are occupied rent-free under facilities contracts that generally require ATK to pay for all utilities, services, and maintenance costs.

24

        Land.    ATK also uses land that it owns or leases for assembly, test, and evaluation, in Brigham City, Corrine, and Magna, UT, which is used by ATK Space Systems and ATK Mission Systems; and in Elk River, MN and Socorro, NM, which is used by ATK Mission Systems.

        ATK personnel also occupy space at the following facilities that are not owned or operated by ATK: Marshall Space Flight Center, Huntsville, AL; Kennedy Space Center, Cape Canaveral, FL; Vandenberg Air Force Base, Vandenberg, CA; and Picatinny Arsenal, Picatinny, NJ.

        ATK's properties are well maintained and in good operating condition and are sufficient to meet ATK's near-term operating requirements.

ITEM 3.    LEGAL PROCEEDINGS

        From time to time, ATK is subject to various legal proceedings, including lawsuits, which arise out of, and are incidental to, the conduct of ATK's business. ATK does not consider any of such proceedings that are currently pending, individually or in the aggregate, to be material to its business or likely to result in a material adverse effect on its future operating results, financial condition, or cash flows.

        On or about April 10, 2006, a former ATK employee filed a qui tam complaint in federal court in Utah alleging that ATK knowingly submitted claims for payment to the U.S. government for defective LUU series illuminating flares that failed to conform to certain safety specifications and falsely certified compliance with those specifications. The lawsuit was initially filed under seal. ATK was first informed of the lawsuit by the United States Department of Justice (DOJ) on March 13, 2007. Thereafter, the DOJ intervened in the qui tam action and filed an amended complaint on November 2, 2007. On May 29, 2008, ATK filed its answer to the complaint. The DOJ subsequently filed a motion to strike the affirmative defenses set forth in ATK's answer. On July 14, 2008, ATK filed its opposition to the motion to strike. On October 16, 2008, the court granted the motion in part and denied it in part. Discovery is underway in the case.

        ATK denies any allegations of improper conduct. Based on what is known to ATK about the subject matter of the complaint, ATK does not believe that it has violated any law or regulation and believes it has valid defenses to all allegations of improper conduct. Although it is not possible at this time to predict the outcome of the litigation, ATK believes, based on all available information, that the outcome will not have a material adverse effect on its operating results, financial condition or cash flows. Some potential, however, does remain for an adverse judgment that could be material to ATK's financial position, results of operations, or cash flows. As a result of the uncertainty regarding the outcome of this matter, no provision has been made in the financial statements with respect to this contingent liability.

        U.S. Government Investigations.    ATK is also subject to U.S. Government investigations from which civil, criminal, or administrative proceedings could result. Such proceedings could involve claims by the U.S. Government for fines, penalties, compensatory and treble damages, restitution, and/or forfeitures. Under government regulations, a company, or one or more of its operating divisions or subdivisions, can also be suspended or debarred from government contracts, or lose its export privileges, based on the results of investigations. ATK believes, based upon all available information, that the outcome of any such pending government investigations will not have a material adverse effect on its operating results, financial condition, or cash flows.

        Environmental Liabilities.    ATK's operations and ownership or use of real property are subject to a number of federal, state, and local laws and regulations, including those for discharge of hazardous materials, remediation of contaminated sites, and restoration of damage to the environment. Due in part to their complexity and pervasiveness, such laws and regulations have resulted in ATK being involved with a number of related legal proceedings, claims, and remediation obligations. ATK

25

routinely assesses, based on in-depth studies, expert analyses, and legal reviews, its contingencies, obligations, and commitments for remediation of contaminated sites and past practices, including assessments of ranges and probabilities of recoveries from other responsible parties. ATK's policy is to accrue and charge to expense in the current period any identified exposures related to environmental liabilities based on estimates of investigation, cleanup, monitoring, and resource restoration costs to be incurred.

        ATK could incur substantial costs, including cleanup costs, resource restoration, fines, and penalties or third-party property damage or personal injury claims, as a result of violations or liabilities under environmental laws or non-compliance with environmental permits. While environmental laws and regulations have not had a material adverse effect on ATK's operating results, financial condition, or cash flows in the past, and ATK has environmental management programs in place to mitigate these risks, it is difficult to predict whether they will have a material impact in the future.

        In late 2007, ATK discovered that a photographic development operation at its ATK Launch Systems facility in Magna, Utah had been intermittently discharging wastewater containing silver above regulated levels into a septic system, in violation of ATK's hazardous waste management permit. ATK immediately ceased discharging the wastewater and notified the State of Utah. In December 2007, ATK provided the State of Utah with a more detailed report of the matter. In response, the State of Utah issued a notice of violation in February 2008 ordering ATK to investigate and, if necessary, mitigate the hazardous waste discharge. In May 2008, the State of Utah issued a proposed stipulation and consent order. Discussions between ATK and the State of Utah resulted in agreement of a penalty of $131,310. In July 2008, the State of Utah issued a final stipulation and consent order settling the matter and sent this consent order for public comment. The public comment period is now complete and ATK paid the agreed-upon amount in fiscal 2009.

        The description of certain environmental matters contained in Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" under the heading "Contingencies" is incorporated herein by reference.

ITEM 4.    SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

        No matter was submitted to a vote of security holders during the fourth quarter of fiscal 2009.

PART II

ITEM 5.    MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITY SECURITIES

        ATK's common stock is listed and traded on the New York Stock Exchange under the symbol "ATK". The following table presents the high and low sales prices of the common stock for the periods indicated:

Period		High		Low
Fiscal 2009:
	Quarter ended March 31, 2009	$	87.79	$	60.76
	Quarter ended December 28, 2008		96.44		70.20
	Quarter ended September 28, 2008		111.67		94.35
	Quarter ended June 29, 2008		114.29		99.28
Fiscal 2008:
	Quarter ended March 31, 2008	$	115.41	$	95.00
	Quarter ended December 30, 2007		120.90		106.37
	Quarter ended September 30, 2007		115.95		98.32
	Quarter ended July 1, 2007		102.81		87.70

        The number of holders of record of ATK's common stock as of May 15, 2009, was 7,990.

        ATK has never paid cash dividends on its common stock. ATK's dividend policy is reviewed by the Board of Directors from time to time as may be appropriate in light of relevant factors existing at such times, including the extent to which the payment of cash dividends may be restricted by covenants contained in ATK's 6.75% Senior Subordinated Notes and Senior Credit Facility (as described under "Liquidity and Capital Resources" in Item 7 of this report). As of March 31, 2009, ATK's 6.75% Senior Subordinated Notes limit the aggregate sum of dividends, share repurchases, and other designated restricted payments to an amount based on ATK's net income, stock issuance proceeds, and certain other items, less restricted payments made, since April 1, 2001. As of March 31, 2009, this limit was approximately $352 million. As of March 31, 2009, the Senior Credit Facility allows ATK to make unlimited "restricted payments" (as defined in the credit agreement), which, among other items, would allow payments for future share repurchases, as long as ATK maintains certain senior debt limits, with an annual limit, when those debt limits are not met, of $50 million plus proceeds of any equity issuances plus 50% of net income since March 29, 2007. The Senior Credit Facility also prohibits dividend payments if loan defaults exist or the financial covenants contained in the Facility are not met.

(1)

No additional awards may be granted under this plan.

(2)

Shares reserved for payment of deferred stock units in accordance with the terms of the plan.

(3)

Under the 2005 Stock Incentive Plan, no more than 1,500,000 shares are available for performance awards, restricted stock awards, restricted stock units, dividend equivalents, and stock awards, and of that number only 50,000 shares may be issued as stock awards. No more than 76,618 shares in the aggregate may be granted pursuant to awards to non-employee directors of ATK.

(4)

Shares reserved for issuance in connection with outstanding performance awards. The amount shown assumes the maximum payout of the performance shares based on achievement of the highest level of performance. The actual number of shares to be issued depends on the performance levels achieved for the respective performance periods.

28

        The 2000 Stock Incentive Plan (the "2000 Plan") is administered by the Personnel and Compensation Committee (the "P&C Committee") of ATK's Board of Directors. ATK stopped granting options and all other awards under the 2000 Plan in January 2004 and is only continuing the plan for the exercise, payment or forfeiture of awards granted in or before January 2004. Under the 2000 Plan, all employees (other than officers and directors), consultants, and independent contractors providing services to ATK or its affiliates were eligible to receive awards. The P&C Committee designated the participants who received awards, determined the types and amounts of awards granted, and determined the terms and conditions of awards granted, subject to the provisions of the 2000 Plan. Awards granted under the 2000 Plan consisted of stock options, restricted stock, and performance awards. Options granted under the 2000 Plan have an exercise price equal to the fair market value of ATK's common stock on the date of grant. Options granted under the 2000 Plan prior to January 2004 vested in three equal annual installments and have a term of 10 years. Options granted in January 2004 vested after three years and have a term of seven years. Options may vest immediately in the event of a change in control of ATK (or, for ATK's executive officers, in the event of a qualifying termination of employment following a change in control) or in the event of a participant's death, disability or retirement. If an option holder's employment terminates, the option remains exercisable for a fixed period of time, as determined by the P&C Committee, up to the remainder of the option's term. Payment of the exercise price of an option may be made in cash or in shares of ATK common stock previously acquired by the option holder.

On August 5, 2008, ATK's Board authorized the repurchase of up to 5 million shares. The Board has currently determined that the repurchase program will serve primarily to offset dilution from the Company's employee and director benefit compensation programs, but it may also be used for other corporate purposes, as determined by the Board. During fiscal 2009, ATK repurchased 299,956 shares for $31.6 million. As of March 31, 2009, there were 4,700,044 remaining shares authorized to be repurchased.

        The discussion of limitations upon the payment of dividends as a result of the indentures governing ATK's debt instruments as discussed in Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" under the heading "Debt," is incorporated herein by reference.

STOCKHOLDER RETURN PERFORMANCE GRAPH

        The following graph compares, for the five fiscal years ended March 31, 2009, the cumulative total return for ATK common stock with the comparable cumulative total return of two indexes:

•

Standard & Poor's Composite 500 Index, a broad equity market index; and

•

Dow Jones U.S. Aerospace and Defense Index, a published industry index.

        The graph assumes that on April 1, 2004, $100 was invested in ATK common stock (at the closing price on the previous trading day) and in each of the indexes. The comparison assumes that all dividends, if any, were reinvested. The graph indicates the dollar value of each hypothetical $100 investment as of March 31 in each of the years 2005, 2006, 2007, 2008, and 2009.

In fiscal 2006, ATK made a cash tender offer for its outstanding $400 million principal aggregate amount 8.50% Senior Subordinated Notes. Fiscal 2006 interest expense reflects $18.8 million for the premium to extinguish the debt, $7.1 million related to deferred financing costs that were written off, and $6.0 million for termination of the related interest-rate swaps.

Overview

        ATK is a premier aerospace and defense company and leading supplier of products to the U.S. government, allied nations, and prime contractors. ATK is also a major supplier of ammunition and related accessories to law enforcement agencies and commercial customers. ATK is headquartered in Minneapolis, Minnesota and has operating locations throughout the United States, Puerto Rico, and internationally.

        During fiscal 2009, ATK realigned its business operations. As a result of this realignment, ATK combined the Space division of ATK Mission Systems with ATK Launch Systems into a single group now known as ATK Space Systems. Following this realignment, ATK has three segments: ATK Armament Systems, ATK Mission Systems, and ATK Space Systems. The fiscal 2009 realignment is reflected in the information contained in this report and the segment information for prior periods has been restated.

•

ATK Armament Systems, which generated 38% of ATK's external sales in fiscal 2009, develops and produces military ammunition and gun systems; commercial products; and propellant and energetic materials. It also operates the U.S. Army ammunition plants in Independence, Missouri and Radford, Virginia.

•

ATK Mission Systems, which generated 26% of ATK's external sales in fiscal 2009, operates in two business lanes, Weapon Systems and Aerospace Systems, across the following market areas: large-caliber direct fires, force protection, precision guided munitions, missiles, propulsion, missile defense, fuzes and warheads, composites, special mission aircraft, electronic warfare, military aircraft structures, commercial aircraft structures, and launch structures.

•

ATK Space Systems, which generated 36% of ATK's external sales in fiscal 2009, produces rocket motor systems for human and cargo launch vehicles, conventional and strategic missiles, missile defense interceptors, small and micro-satellites, satellite components, structures and subsystems, lightweight space deployables and solar arrays, and provides engineering and technical services. Other products include ordnance, such as decoy and illuminating flares.

33

        ATK is dependent on funding levels of the U.S. Department of Defense ("DoD") and NASA. The U.S. defense industry has experienced significant changes over the years. ATK management believes that the key to ATK's continued success is to focus on performance, innovation, simplicity, and affordability, and that ATK's future lies in being a leading provider of advanced weapon and space systems. ATK is positioning itself where management believes there will be continued strong defense funding, even as pressures mount on procurement and research and development accounts. ATK will concentrate on developing systems that will extend the life and improve the capability of existing platforms. ATK anticipates budget pressures will increasingly drive the life extension of platforms such as ships, aircrafts, and main battle tanks. ATK's transformational weapons such as Excalibur, Advanced Anti-Radiation Guided Missile, and the Precision Guidance Kit are aimed squarely at this growing market. At the same time, ATK believes it is on the leading edge of technologies essential to "generation after next" weapons and platforms—advanced sensor/seeker integration; directed energy; weapon data links; high-speed; long-range projectiles; thermal-resistant materials; reactive materials; and scramjet engines are examples.

Critical Accounting Policies

        ATK's discussion and analysis of its financial condition and results of operations are based upon ATK's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. In preparing the consolidated financial statements, ATK makes estimates and judgments that affect the reported amounts of assets, liabilities, sales, expenses, and related disclosure of contingent assets and liabilities. ATK re-evaluates its estimates on an on-going basis. ATK's estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

        ATK believes the following are its critical accounting policies that affect its more significant judgments and estimates used in the preparation of its consolidated financial statements.

Revenue Recognition

Long-Term Contracts—Sales under long-term contracts are accounted for under the percentage-of-completion method and include cost-plus and fixed-price contracts. Sales under cost-plus contracts are recognized as costs are incurred. Sales under fixed-price contracts are either recognized as the actual cost of work performed relates to the estimate at completion ("cost-to-cost") or based on results achieved, which usually coincides with customer acceptance ("units-of-delivery"). The majority of ATK's total revenue is accounted for using the cost-to-cost method of accounting.

        Profits expected to be realized on contracts are based on management estimates of total contract sales value and costs at completion. Estimated amounts for contract changes and claims are included in contract sales only when realization is estimated to be probable. Assumptions used for recording sales and earnings are adjusted in the period of change to reflect revisions in contract value and estimated costs. In the period in which it is determined that a loss will be incurred on a contract, the entire amount of the estimated gross margin loss is charged to cost of sales.

        Contracts may contain provisions to earn incentive and award fees if specified targets are achieved. Incentive and award fees that can be reasonably estimated and are probable are recorded over the performance period of the contract. Incentive and award fees that cannot be reasonably estimated are recorded when awarded.

        The complexity of the estimation process and all issues related to assumptions, risks, and uncertainties inherent with the application of the cost-to-cost method of accounting affect the amounts reported in ATK's financial statements. A number of internal and external factors affect the cost of sales estimates, including labor rate and efficiency variances, overhead rate estimates, revised estimates

34

of warranty costs, estimated future material prices, and customer specification and testing requirement changes. If business conditions were different, or if ATK had used different assumptions in the application of this and other accounting policies, it is likely that materially different amounts would be reported in ATK's financial statements. In the past, ATK's estimates and assumptions have been materially accurate.

Commercial Products—Sales are recognized when persuasive evidence of an arrangement exists, the product has been delivered and legal title and all risks of ownership have been transferred, written contract and sales terms are complete, customer acceptance has occurred, and payment is reasonably assured. Sales are reduced for allowances and price discounts.

Environmental Remediation and Compliance

        Costs associated with environmental compliance and preventing future contamination that are estimable and probable are accrued and expensed, or capitalized as appropriate. Expected remediation, resource restoration, and monitoring costs relating to the remediation of an existing condition caused by past operations, and which do not contribute to current or future revenue generation, are accrued and expensed in the period that such costs become estimable. Liabilities are recognized for remedial and resource restoration activities when they are probable and the cost can be reasonably estimated. As of March 31, 2009, the estimated discounted range of reasonably possible costs of environmental remediation, excluding potential recoveries as discussed under the "Contingencies" heading below, was $56,282 to $85,836.

        ATK's engineering, financial, and legal specialists estimate, based on current law and existing technologies, the cost of each environmental liability. Such estimates are based primarily upon the estimated cost of investigation and remediation required and the likelihood that other potentially responsible parties ("PRPs") will be able to fulfill their commitments at the sites where ATK may be jointly and severally liable. ATK's estimates for environmental obligations are dependent on, and affected by, the nature and extent of historical information and physical data relating to a contaminated site, the complexity of the site, methods of remediation available, the technology that will be required, the outcome of discussions with regulatory agencies and other PRPs at multi-party sites, the number and financial viability of other PRPs, changes in environmental laws and regulations, future technological developments, and the timing of expenditures. Accordingly, such estimates could change materially as ATK periodically evaluates and revises such estimates based on expenditures against established reserves and the availability of additional information.

Employee Benefit Plans

        Defined Benefit Pension Plans.    ATK's noncontributory defined benefit pension plans (the "Plans") cover substantially all employees hired prior to January 1, 2007. Eligible non-union employees hired on or after January 1, 2007 and certain union employees are not covered by a defined benefit plan but do receive an employer contribution through a defined contribution plan. Plans provide either pension benefits based on employee annual pay levels and years of credited service or based on stated amounts for each year of credited service. ATK funds the Plans in accordance with federal requirements calculated using appropriate actuarial methods. Plan assets for ATK are held in a trust and are invested in a diversified portfolio of equity investments, fixed income investments, real estate, timber, energy investments, hedge funds, private equity, and cash. For certain Plan assets where the fair market value is not readily determinable, estimates of the fair value are determined using the best available information including the most recent audited financial statements.

        ATK also sponsors nonqualified supplemental executive retirement plans which provide certain executives and highly compensated employees the opportunity to receive pension benefits in excess of those payable through tax qualified pension plans.

35

        ATK recorded pension expense for the Plans of $39,972 in fiscal 2009, a decrease of $10,221 from $50,193 of pension expense recorded in fiscal 2008. The expense related to these Plans is calculated based upon a number of actuarial assumptions, including the expected long-term rate of return on plan assets, the discount rate, and the rate of compensation increase. The following table sets forth ATK's assumptions used in determining pension expense for fiscal 2009, 2008, and 2007, and projections for fiscal 2010:

		Years Ending March 31
		2010			2009			2008			2007
Expected long-term rate of return on plan assets			8.00	%		9.00	%		9.00	%		9.00	%
Discount rate			8.15	%		6.80	%		6.10	%		5.80	%
Rate of compensation increase:
	Union		3.82	%		3.75	%		3.50	%		3.00	%
	Salaried		4.09	%		3.95	%		3.73	%		3.25	%

        In developing the expected long-term rate of return assumption, ATK considers input from its actuaries and other advisors, annualized returns of various major indices over 20-year periods, and ATK's own historical investment returns, which have been in excess of broad market indices. The expected long-term rate of return of 9.0% used in fiscal 2009 for the Plans was based on an asset allocation range of 30-60% in equity investments, 20-30% in fixed income investments, 5-15% in real estate/real asset investments, 10-25% collectively in hedge fund and private equity investments, and 0-5% in cash investments. The actual return in any fiscal year will likely differ from ATK's assumption, but ATK estimates its return based on long-term projections and historical results. Therefore, any variance in a given year does not necessarily indicate that the assumption should be changed.

        In determining its discount rate, ATK uses the current investment yields on high-quality corporate bonds (rated AA or better) that coincide with the cash flows of the estimated benefit payouts from ATK's plans. The model uses a yield curve approach to discount each cash flow of the liability stream at an interest rate specifically applicable to the timing of the respective cash flow. The model totals the present values of all cash flows and calculates the equivalent weighted average discount rate by imputing the singular interest rate that equates the total present value with the stream of future cash flows. This resulting weighted average discount rate is then used in evaluating the final discount rate. The discount rate was 8.15%, 6.80%, and 6.10% at March 31, 2009, March 31, 2008, and December 31, 2007, respectively. The discount rate as of March 31 impacts the following fiscal year's pension expense.

        Future actual pension expense can vary significantly depending on future investment performance, changes in future discount rates, legally required plan changes, and various other factors related to the populations participating in the Plans. If the assumptions of the discount rate, compensation increase, and/or expected rate of return for fiscal 2010 were different, the impact on fiscal 2010 expense would be as follows: each 0.25% change in the discount rate would change fiscal 2010 pension expense by approximately $5,500; each 0.25% change in the rate of compensation increase would change fiscal 2010 pension expense by approximately $4,000; each 0.25% change in the expected rate of return on plan assets would change fiscal 2010 pension expense by approximately $5,400.

        ATK bases its determination of pension expense or income on a market-related valuation of assets, which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return based on the market-related value of assets. Since the market-related value of assets recognizes gains or losses over a five-year period, the future value of assets will be impacted as previously deferred gains or losses are recorded.

36

        ATK did not make any contributions to the qualified pension trust fund during fiscal 2009. ATK made a qualified pension plan trust prepayment contribution of $150,000 in April 2009 (fiscal 2010) of which $45,000 was the legally required minimum contribution for fiscal 2010. ATK distributed $2,898 directly to retirees under its supplemental executive retirement plans during fiscal 2009, and expects to make distributions directly to retirees of approximately $3,137 in fiscal 2010. A substantial portion of ATK's Plan contributions are recoverable from the U.S. Government as allowable indirect contract costs at amounts generally equal to the pension plan contributions, although not necessarily in the same year the contribution is made.

        In September 2006, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 158, Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans—an amendment of FASB Statements No. 87, 88, 106 and 132(R) ("SFAS No. 158"), which required recognition of the funded status of defined benefit pension and other postretirement plans, with a corresponding after-tax adjustment to accumulated other comprehensive loss. Due to the adoption of these provisions of SFAS No. 158, differences between actual and expected returns on assets, changes in assumptions, and changes in plan provisions could significantly increase or decrease stockholders' equity.

        Effective April 1, 2007, ATK adopted the measurement provisions of SFAS No. 158 which required ATK to remeasure its Plan assets and benefit obligations as of March 31. Prior to that adoption, ATK remeasured its Plan assets and benefit obligations as of December 31. Other than a change in the discount rate from 5.90% to 6.10%, the assumptions used to remeasure the assets and liabilities remained unchanged from fiscal 2007. The after-tax cumulative effect changes of this adoption included a decrease of approximately $9,000 in retained earnings, a decrease of approximately $47,600 in accumulated other comprehensive loss, an increase of approximately $30,700 in total assets, and a decrease of approximately $7,900 in total liabilities.

        Other Postretirement Benefits.    ATK also provides postretirement health care benefits and life insurance coverage to certain employees and retirees.

        The following table sets forth ATK's assumptions used to determine net periodic benefit cost for other postretirement benefit ("PRB") plans for fiscal 2009, 2008, and 2007, and projections for fiscal 2010:

		Years Ending March 31
		2010			2009			2008			2007
Expected long-term rate of return on plan assets:
	Held solely in fixed income investments		6.00	%		6.00	%		6.00	%		6.00	%
	Held in pension master trust and fixed income investments		7.00	%		8.00	%		8.00	%		8.00	%
Discount rate			7.90	%		6.80	%		6.10	%		5.80	%
Weighted average initial health care cost trend rate			6.90	%		7.20	%		7.30	%		7.20	%

        Health care cost trend rates are set specifically for each benefit plan and design. Health care cost trend rates used to determine the net periodic benefit cost for employees during fiscal 2009 were as follows: under age 65 was 8.0%; over age 65 was 6.5%; and the prescription drug portion was 12.5%.

        The rates to which the health care cost trend rates are assumed to decline (the ultimate trend rates) are as follows:

Health care cost trend rate for employees under 65	5.5	%
Health care cost trend rate for employees over 65	5.0	%
Health care cost trend rate for prescription drugs	7.0	%
Weighted average health care cost trend rate	5.4	%

37

        Each category of cost declines at a varying rate. The ultimate trend rate will be reached in fiscal 2014 for employees under age 65, in fiscal 2016 for employees over age 65, and in fiscal 2017 for prescription drugs.

        In developing the expected long-term rate of return assumption for other PRB plans, ATK considers input from actuaries, historical returns, and annualized returns of various major indices over long periods. As of March 31, 2009, approximately 33% of the assets were held in a 401(h) account held within the pension master trust and are invested in the same manner as the pension assets. The expected long-term rates of returns are based on the weighted average asset allocation between the assets held within the 401(h) and those held in fixed income investments.

        Assumed health care cost trend rates have a significant effect on the amounts reported for health care plans. A one-percentage point increase or decrease in the assumed health care cost trend rates would have the following effects:

	One-Percentage Point Increase		One-Percentage Point Decrease
Effect on total service and interest cost	$	589	$	(527	)
Effect on postretirement benefit obligation		7,465		(6,689	)

        ATK made other PRB plan contributions of $13,792 in fiscal 2009 and expects to make contributions of approximately $14,700 in fiscal 2010.

        The Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Act) reduced ATK's accumulated projected benefit obligation ("APBO") measured as of December 31, 2005. One of ATK's other PRB plans is actuarially equivalent to Medicare, but ATK does not believe that the subsidies it will receive under the Act will be significant. Because ATK believes that participation levels in its other PRB plans will decline, the impact to ATK's results of operations in any period has not been and is not expected to be significant.

        Defined Contribution Plan.    ATK also sponsors a 401(k) defined contribution plan. Participation in this plan is available to substantially all employees.

Income Taxes

        Provisions for federal and state income taxes are calculated based on reported pre-tax earnings and current tax law. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions. ATK periodically assesses its liabilities and contingencies for all periods that are currently open to examination or have not been effectively settled based on the most current available information. Where it is not more likely than not that ATK's tax position will be sustained, the Company records the entire resulting tax liability and when it is more likely than not of being sustained, the Company records its best estimate of the resulting tax liability. Any applicable interest and penalties related to these positions are also recorded in the consolidated financial statements. To the extent ATK's assessment of the tax outcome of these matters changes, such change in estimate will impact the income tax provision in the period of the change. It is ATK's policy to record any interest and penalties related to income taxes as part of the income tax expense for financial reporting purposes.

Acquisitions

        In accordance with SFAS 141, Business Combinations, ATK uses the purchase method of accounting to account for its acquisitions, and, accordingly, the results of acquired businesses are

38

included in ATK's consolidated financial statements from the date of acquisition. The purchase price for acquisitions is allocated to the acquired assets and liabilities based on fair value. Estimates are used in determining the fair value and estimated remaining lives of intangible assets until the final purchase price allocation is completed. Actual fair values and remaining lives of intangible assets may vary from those estimates. The excess purchase price over the estimated fair value of the net assets acquired is recorded as goodwill.

        On March 31, 2009, ATK acquired Eagle Industries ("Eagle"), a leading manufacturer of high-quality, individual operational nylon gear and equipment for military, homeland security, and law enforcement agencies for $63,000 net of cash acquired, subject to purchase price contingencies. Eagle manufactures more than 5,000 products which include tactical assault vests, load-bearing equipment, weapon transporting gear, holsters, personal gear carriers, and other high quality accessories. ATK believes that the acquisition provides an opportunity to expand its position in the domestic and international tactical accessories markets serving military and law enforcement customers. Headquartered in Fenton, Missouri, Eagle employs approximately 2,300 employees and is included in ATK Armament Systems. The purchase price allocation has not yet been completed, pending final valuation of certain acquired assets and liabilities. The final purchase price allocation could be significantly different than the estimate currently recorded. A portion of the goodwill generated in this acquisition will be deductible for tax purposes.

        On June 8, 2007, ATK acquired Swales Aerospace ("Swales"), a provider of satellite components and subsystems, small spacecraft and engineering services for NASA, Department of Defense and commercial satellite customers, for $101,195 net of cash acquired. ATK believes that the acquisition strengthened ATK's satellite components, subsystems and small spacecraft portfolios and further increased ATK's position as a supplier to the U.S. Government and industry. ATK also believes the acquisition enhanced ATK's systems engineering as ATK pursues strategic initiatives in space exploration programs. Headquartered in Beltsville, Maryland, Swales employs approximately 626 employees and is included in ATK Space Systems.

        During fiscal 2003, ATK acquired the assets of Science and Applied Technology, Inc. (included in ATK Mission Systems). The sellers of this acquired business had the ability to earn up to an additional $7,500 of cash consideration if certain pre-specified milestones were attained with respect to one of the contracts acquired. The pre-specified milestones were met in September 2008 and the additional contingent consideration earned pursuant to the purchase agreement resulted in an increase to goodwill.

        ATK did not make any acquisitions during fiscal 2007.

Accounting for Goodwill

        In accordance with SFAS No. 142, Goodwill and Other Intangible Assets ("SFAS No. 142"), ATK tests goodwill and intangible assets with indefinite lives for impairment on an annual basis or upon the occurrence of events that may indicate possible impairment. SFAS 142 requires that goodwill be tested as of the same date every year; ATK's annual testing date is the first day of its fourth fiscal quarter, which was December 29, 2008, for our fiscal 2009 analysis. In accordance with SFAS No. 142, the Company determined that the reporting units for its goodwill impairment review are its operating segments, or components of an operating segment, that constitute a business for which discrete financial information is available, and for which segment management regularly reviews the operating results. Based on this analysis, the Company has identified ten reporting units within its reportable segments as of December 29, 2008.

        SFAS No. 142 prescribes a two-step process for determining goodwill impairment. In the first step, ATK determines the estimated fair value of each reporting unit and compares that estimated fair value to the carrying value of such reporting unit, including goodwill. If the results of the first step indicate

39

that the carrying amount of a reporting unit is higher than its fair value, the second step must be performed. Specifically, SFAS No. 142 prescribes that in the second step, ATK must determine the implied fair value of goodwill in the same manner as if ATK had acquired those reporting units in a business combination. In the second step, the potential impairment is computed by comparing the implied fair value of the reporting unit's goodwill with the carrying amount of goodwill. If the carrying amount of the reporting unit's goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess.

        ATK begins its assessment by using a discounted cash flow approach ("income approach"). ATK uses its three-year plan, as approved by the Board of Directors, and assumes a terminal growth rate thereafter. These cash flows are then discounted using ATK's composite discount rate. ATK ensures that the consolidated cash flows reconcile to the market capitalization at the test date using an assumed control premium. ATK then computes the break-even discount rate for each reporting unit and compares that to ATK's composite rate to determine if further analysis is needed for a particular reporting unit.

        For the initial assessment of fiscal 2009 impairment analysis, ATK calculated a composite discount rate of 10.1% using a 3% terminal growth rate and a 30% control premium. The results of ATK's initial assessment indicated that all reporting units except the Spacecraft Systems division could support a discount rate at least 300 basis points above the ATK composite discount rate and therefore there was no indicator of impairment in any reporting unit in the first step except the Spacecraft Systems reporting unit, for which additional analysis was performed.

        ATK engaged an independent valuation specialist to assist in the determination of the estimated fair value of the Spacecraft Systems reporting unit, using a discounted cash flow analysis ("income approach"), corroborated by comparative market multiples ("market approach"). The estimated fair value under each approach was weighted equally to compute one estimated fair value for the reporting unit, which was below the carrying value of the reporting unit. Accordingly, the second step of the impairment review was required. ATK allocated the estimated fair value of the reporting unit to all of the assets, including any unrecognized intangible assets, and liabilities of that unit, in a calculation that yielded the implied fair value of goodwill. The impairment loss is measured as the difference between the book value of the goodwill and the estimated fair value of the goodwill computed in step two. Based on the results of the second step of the impairment review, ATK recorded a non-cash goodwill impairment charge of $108,500 in our Spacecraft Systems reporting unit. The remaining goodwill recorded within the Spacecraft Systems reporting unit is $145,647 at March 31, 2009. The goodwill impairment charge was attributed to changes in future estimated cash flows, the substantial reduction in the market multiples, and the implied valuation of this and comparable companies.

        These calculations are based on inherent assumptions and estimates about future cash flows and appropriate benchmark peer companies or groups. Subsequent changes in these assumptions could result in future impairment. Although the Company consistently uses the same methods in developing the assumptions and estimates underlying the fair value calculations, such estimates are uncertain by nature and can vary from actual results. Each 0.5 change in the EBITDA multiple and 0.5% change in the discount rate would impact the Spacecraft reporting unit's impairment by approximately $15.0 million.

Results of Operations

        The following information should be read in conjunction with ATK's consolidated financial statements. The key performance indicators that ATK's management uses in managing the business are sales, income before interest and income taxes, and cash flows.

Total external sales	$	4,583,224	$	4,171,725	$	411,499		9.9	%

        The increase in sales was due to organic growth as well as the acquisition of Swales late in the first quarter of fiscal 2008, as previously discussed, which is reported within ATK Space Systems.

        ATK Armament Systems.    The increase in sales was driven by:

•

an increase of $111,100 in commercial products due to an increase in volume of law enforcement, international, and commercial sales,

•

a $103,900 increase in medium-caliber systems due to higher volume across multiple ammunition programs as well as higher demand in medium-caliber guns,

•

a $34,100 increase in military small-caliber ammunition sales at the Lake City Army ammunition plant as a result of continued strong customer requirements and modernization project sales, and

•

an increase of $11,900 in energetic systems at the Radford Army Ammunition Plant relating to modernization project sales and increased nitrocellulous sales.

        ATK Mission Systems.    The increase in sales was driven by:

•

an increase of $38,100 in tactical rocket motors due to higher volume across numerous programs,

•

a $20,900 increase due to the new contract for the attitude control motor on the Orion Crew Exploration Vehicle (CEV) launch abort system,

•

an increase of $20,300 due to higher volume in aircraft integration,

•

a new composite rotor tubes program for United States Enrichment Corporation (USEC) which added $21,000,

•

a $19,300 increase in commercial aircraft structures resulting primarily from a new commercial aircraft program, and

•

an increase of $17,700 due to a new international force protection system.

        These increases were partially offset by:

•

a decrease of $29,500 in technical services due to reduced volume,

•

a $17,600 decline in large-caliber direct fires due to lower volumes across multiple programs, and

•

a $12,900 decrease resulting from the successful completion of the Shielder Canister program.

41

        ATK Space Systems.    The increase in sales was driven by:

•

a net increase of $123,600 on ARES I and Space Shuttle programs,

•

an increase of $29,600 due to the inclusion of Swales which was acquired late in the first quarter of fiscal 2008,

•

a $17,800 increase for Trident II missile production and support timing, and

•

an increase of $16,400 relating to overlapping Orion production lots and additions to the scope of the Kinetic Energy Inceptor program.

        These increases were partially offset by:

•

a decrease in Minuteman volume of $38,000 due to the contract nearing successful completion,

•

a decrease of $23,500 due to lower customer demand and production delays in decoys and flares,

•

a $20,400 decrease on the Launch Abort System due to funding limitations,

•

a decrease in solar arrays of $18,100 as a result of decreased volume and performance issues, and

•

a $14,500 decrease in bus structures due to performance issues and schedule delays.

	Total	$	591,455		12.9	%	$	415,787		10.0	%	$	175,668

        Operating expenses increased primarily due to higher selling expenses consistent with higher sales over the prior year period, as well as increased program proposal efforts within ATK Mission Systems and ATK Space Systems and the non-cash goodwill impairment charge totaling $108,500 within Spacecraft Systems, as previously discussed. Research and development expenses were up due to increased spending on major launch vehicle programs within ATK Space Systems, increased volume within medium-caliber systems, as well as within ATK Mission Systems. General and administrative expenses were up as a result of increased spending to support increasing sales and a $13,000 increase in bad debt expense in fiscal 2009 within commercial products relating to increased customer credit risk. These increases were partially offset by the absence of a $6,567 charge for transaction-related costs

42

related to an acquisition that was terminated in fiscal 2008, and lower share-based compensation expenses compared to the prior year.

Income before Interest, Income Taxes, and Minority Interest

		Years Ended March 31
		2009			2008			Change
ATK Armament Systems		$	171,563		$	139,603		$	31,960
ATK Mission Systems			153,341			129,028			24,313

	Total	$	384,457		$	430,528		$	(46,071	)

        The decrease in income before interest, income taxes, and minority interest was due to the non-cash goodwill impairment charge within ATK Space Systems and higher operating expenses as discussed above, partially offset by higher sales. Significant changes within the operating segments are also described below.

        ATK Armament Systems.    The increase primarily relates to higher overall sales volume as well as improved margins in commercial products and medium-caliber guns and ammunition programs. These increases were partially offset by a $13,000 increase in bad debt expense in fiscal 2009 within commercial products relating to increased customer credit risk.

        ATK Mission Systems.    The increase was primarily driven by higher sales within aircraft integration, commercial aircraft structures, tactical rocket motors, and space stage motors, partially offset by margin declines within force protection and fuze operations due to technical issues on the FMU-139 bomb fuze program and the Spider advanced munitions program.

        ATK Space Systems.    The decrease was primarily due to the non-cash goodwill impairment charge totaling $108,500 within Spacecraft Systems, as previously discussed, as well as performance issues and schedule delays in the spacecraft structures business. These items were partially offset by higher sales volume.

        Corporate.    The net expense of Corporate primarily reflects expenses incurred for administrative functions that are performed centrally at the corporate headquarters, the elimination of intercompany profits, and stock option expense. The decrease is due primarily to the absence of a $6,567 charge for transaction-related costs related to an acquisition that was terminated in fiscal 2008, as well as a decrease in stock option expense from the prior year.

Net Interest Expense

        Net interest expense for fiscal 2009 was $62,487, a decrease of $17,660 compared to $80,147 in fiscal 2008. The decrease was primarily due to the accelerated noncash write-off of $5,600 of debt issuance costs which was the result of the 3.00% Convertible Senior Subordinated Notes and the 2.75% Convertible Senior Subordinated Notes due 2024 becoming convertible in fiscal 2008 as well as a decrease in the average borrowing rate and average outstanding debt balance.

        As discussed in Note 1, Summary of Significant Accounting Policies, to the consolidated financial statements, the Financial Accounting Standards Board (FASB) issued FASB Staff Position (FSP) No. APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement) (FSP No. APB 14-1). The provisions of this FSP apply to ATK's $200,000 aggregate principal amount of 3.00% Convertible Notes, the $280,000 aggregate principal

43

amount of 2.75% Convertible Notes due 2024, and the $300,000 aggregate principal amount of 2.75% Convertible Notes due 2011, discussed in Note 9, Long-Term Debt. This FSP is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years (ATK's fiscal 2010), and shall be applied retrospectively to all periods presented. Early adoption is not permitted. The adoption of the FSP will result in an increase to fiscal 2005 through fiscal 2009 non-cash interest expense in the range of $9,300 to $23,900 per year. The impact to fiscal 2010 non-cash interest expense is expected to be an increase of approximately $19,900 with a declining impact in future fiscal years.

Income Tax Provision

	Years Ended March 31
	2009		Effective Rate			2008		Effective Rate			Change
Income tax provision	$	166,664		51.8	%	$	127,658		36.4	%	$	39,006

        ATK's provision for income taxes includes both federal and state income taxes. The effective tax rate for fiscal 2009 of 51.8% differs from the federal statutory rate of 35% due to the non-deductibility for tax purposes of the non-cash goodwill impairment charge, valuation allowance related to capital loss carryovers, state income taxes, and other provision adjustments which increased the rate, and the domestic manufacturing deduction ("DMD") and research and development ("R&D") tax credits which decreased the rate.

        The effective tax rate for fiscal 2008 of 36.4% differs from the federal statutory rate of 35% due to state income taxes and other provision adjustments which increased the rate, and DMD, R&D tax credits, and changes in previous contingencies which decreased the rate.

        ATK or one of its subsidiaries files income tax returns in the U.S. federal, various U.S. state, and foreign jurisdictions. With few exceptions, ATK is no longer subject to U.S. federal, state and local, or foreign income tax examinations by tax authorities for years prior to 2002. The Internal Revenue Service has completed the audits of ATK through fiscal 2006. ATK is subject to examination in the U.S. federal tax jurisdiction for fiscal 2007 and fiscal 2008. We believe appropriate provisions for all outstanding issues have been made for all open years in all jurisdictions.

        As of March 31, 2009 and 2008, the total amount of unrecognized tax benefits was $25,828 and $19,561, respectively, of which $20,407 and $16,819, respectively, would affect the effective tax rate, if recognized. The remaining balance is related to deferred tax items which only impact the timing of tax payments. In the next 12 months it is reasonably possible that the gross liability for unrecognized tax benefits will decrease by $1,125 primarily as a result of the lapsing of statutes of limitations. See Note 11 to the consolidated financial statements for further details.

        ATK believes it is more likely than not that the recorded deferred benefits will be realized through the reduction of future taxable income. The valuation allowance of $7,608 at March 31, 2009 relates to capital loss carryovers and certain state net operating loss and credit carryforwards that are not expected to be realized before their expiration. The valuation allowance was increased by $4,700 during fiscal 2009 primarily related to the recognition of a valuation allowance for the deferred tax assets related to capital loss carryovers of $5,929. The amount was reduced by $1,229 due to the expiration of a capital loss carryforward, expiration of state credit carryforwards, and a change in the amount of state carryforward benefits expected to be utilized before expiration.

        The federal R&D tax credit was extended through December 31, 2009. If the federal R&D tax credit is not extended through the end of the fiscal year there would be an unfavorable impact on ATK's fiscal 2010 effective income tax rate.

44

Minority Interest

        The minority interest represents the minority owner's portion of the income of a joint venture in which ATK is the primary owner. This joint venture was acquired with Composite Optics, Inc. ("COI") and is consolidated into ATK's financial statements.

Net Income

        Net income for fiscal 2009 was $155,119, a decrease of $67,228 compared to $222,347 in fiscal 2008. The decrease was due to the non-cash goodwill impairment charge of $108,500, increases in operating expenses of $67,168, and the income tax provision of $39,006, partially offset by an increase of $129,597 in gross profit and a decrease in net interest expense of $17,660.

Fiscal 2008

Sales

        The following is a summary of each operating segment's external sales:

	Years Ended March 31
	2008		2007		$ Change		% Change
ATK Armament Systems	$	1,476,716	$	1,276,228	$	200,488		15.7	%

Total external sales	$	4,171,725	$	3,565,072	$	606,653		17.0	%

        The increase in sales was driven by the acquisition of Swales during fiscal 2008 and organic growth in the existing businesses.

        ATK Armament Systems.    The increase in sales was driven by:

•

an increase of $101,700 in commercial products due to an increase in volume of domestic, law enforcement, OEM, and international sales, along with price increases,

•

an increase of $50,500 in medium-caliber guns and ammunition due to various new programs, and

•

a $44,000 increase in military small-caliber ammunition sales at the Lake City Army Ammunition Plant as a result of continued strong customer requirements.

        ATK Mission Systems.    The increase in sales was driven by:

•

a $34,900 increase due to the new contract for the attitude control motor for the CEV launch abort system,

•

an increase of $26,200 in missile defense, primarily due to increased volume on the Standard Missile-3 program,

a $16,700 increase in barrier systems, due to the Spider advanced munition program transitioning to production, and

•

an increase of $11,000 due to increased volume on the Shielder anti-tank barrier system.

        These increases were partially offset by:

•

a $19,800 decline in technical services due to decreased orders,

•

a $19,400 decrease in missile systems, specifically the Advanced Anti-radiation Guided Missile (AARGM) due to program timing, and

•

a decrease of $16,700 in fuzes due to completion of a fuze program.

        ATK Space Systems.    The increase in sales was due to:

•

an increase of $133,600 due to the acquisition of Swales during fiscal 2008,

•

an increase of $133,600 on Ares I,

•

an increase of $41,900 on the new launch abort system for the Orion Crew Exploration Vehicle (CEV),

•

an increase of $12,700 for higher volume of solar array and deployable satellite components,

•

an $8,000 increase due to higher demand for Castor® rocket motor systems and favorable contract performance, and

•

a $6,500 increase due to the resolution of a prior year overhead rate matter.

        These increases were partially offset by:

•

a decrease of $18,000 due to decreased volumes of U.S. Air Force sales, and

•

a decrease of $15,700 on the Space Shuttle program due to synergies with the Ares I program.

	Total	$	415,787		10.0	%	$	346,633		9.7	%	$	69,154

        Operating expenses increased primarily due to higher selling expenses consistent with higher sales, specifically within the commercial products business, increased program proposal efforts primarily within ATK Mission Systems, and the acquisition of Swales. General and administrative expenses were

46

up as a result of a $6,567 charge for transaction-related costs related to an acquisition that was terminated in fiscal 2008, increased spending including higher headcount to support increasing sales partially offset by the absence of a charge of $9,300 related to the termination of an internal information systems project which occurred in fiscal 2007. Research and development expenses were up due to increased spending on major launch vehicle programs within ATK Space Systems.

Income before Interest, Income Taxes, and Minority Interest

		Years Ended March 31
		2008			2007			Change
ATK Armament Systems		$	139,603		$	112,614		$	26,989

Corporate			(31,098	)		(34,792	)		3,694
	Total	$	430,528		$	339,728		$	90,800

        The increase in income before interest, income taxes, and minority interest was due to higher sales and a reduction in pension expense, partially offset by increased operating expenses as discussed above. Significant changes within the operating segments are also described below.

        ATK Armament Systems.    The increase relates to higher sales in all areas along with margin improvement in the TNT program which incurred start up costs in the prior year, partially offset by an increase in the cost of materials.

        ATK Mission Systems.    The increase was driven by organic growth and improved contract performance in defense electronics, force protection, and missile defense. These increases were partially offset by cost growth due to technical issues and schedule delays in missile systems, as well as increased program proposal efforts.

        ATK Space Systems.    The increase was mainly due to the acquisition of Swales, as previously discussed, higher sales on Ares I and the launch abort system, along with the resolution of a prior year overhead rate matter, as previously discussed. These increases were partially offset by technical issues and schedule delays in bus structures and space launch vehicle structures, as well as favorable contract performance on the GEM motors that was recognized in the prior year.

        Corporate.    The net expense of Corporate primarily reflects expenses incurred for administrative functions that are performed centrally at the corporate headquarters, the elimination of intercompany profits, and stock option expense. The decrease is primarily due to a charge of $9,300 related to the termination of an internal information systems project in fiscal 2007 partially offset by the $6,567 charge for transaction-related costs in fiscal 2008, discussed above.

Net Interest Expense

        Net interest expense for fiscal 2008 was $80,147, an increase of $5,215 compared to $74,932 in fiscal 2007. The increase was primarily due to the accelerated non-cash write-off of $5,600 of debt issuance costs during fiscal 2008 discussed below in the "Liquidity and Capital Resources" section under the heading "Debt."

Income Tax Provision

	Years Ended March 31
	2008		Effective Rate			2007		Effective Rate			Change
Income Tax Provision	$	127,658		36.4	%	$	80,217		30.3	%	$	47,441

        ATK's provision for income taxes includes both federal and state income taxes. The effective tax rate for fiscal 2008 of 36.4% differs from the federal statutory rate of 35% due to state income taxes and other provision adjustments which increased the effective rate, and the following items which decreased the rate: DMD, R&D tax credits, and changes in previous contingencies.

        The effective tax rate for fiscal 2007 of 30.3% differs from the federal statutory rate of 35% due to state income taxes which increased the effective rate, and the following items which decreased the rate: the tax benefit from the favorable resolution of federal and state audit issues, extraterritorial income ("ETI") exclusion tax benefits, R&D tax credits, DMD, other provision adjustments, and a decrease in the valuation allowance.

        ATK or one of its subsidiaries files income tax returns in the U.S. federal, various U.S. state, and foreign jurisdictions. With few exceptions, ATK is no longer subject to U.S. federal, state and local, or foreign income tax examinations by tax authorities for years prior to 2001. The Internal Revenue Service has completed the audits of ATK through fiscal 2006.

        As of March 31, 2008 and April 1, 2007, the total amount of unrecognized tax benefits was $19,561 and $16,244, respectively, of which $16,819 and $13,554, respectively, would affect the effective tax rate, if recognized. In the next 12 months it is reasonably possible that the gross liability for unrecognized tax benefits will decrease by $1,602 primarily as a result of the lapsing of statutes of limitations.

        At March 31, 2008, ATK had gross deferred tax assets of $616,989, including $5,932 of state credit carryforwards and $6,386 of state loss carryforwards, which are subject to various limitations and will expire if unused within their respective carryforward periods. ATK has assessed the likelihood that the deferred tax assets will be realized in future years based on projected taxable income and, to the extent that recovery is not more likely than not, a valuation allowance has been established. The valuation allowance of $2,908 at March 31, 2008 relates to certain state net operating loss and credit carryforwards that are not expected to be realized before their expiration.

        The federal R&D tax credit expired on December 31, 2007. Congress is currently considering bills that would extend the credit. If the federal R&D tax credit is not retroactively enacted there could be an unfavorable impact on ATK's fiscal 2009 effective income tax rate.

Minority Interest

        The minority interest represents the minority owner's portion of the income of a joint venture in which ATK is the primary owner. This joint venture was acquired with Composite Optics, Inc. ("COI") and is consolidated into ATK's financial statements.

Net Income

        Net income for fiscal 2008 was $222,347, an increase of $38,219 compared to $184,128 in fiscal 2007. The increase was due to an increase of $159,954 in gross profit, offset by increases in operating expenses of $69,154, income tax provision of $47,441, and net interest expense of $5,215.

Cash Flows

Fiscal 2009

		Years Ended March 31
		2009			2008			Change
Cash flows provided by operating activities		$	424,987		$	382,751		$	42,236
Cash flows used for investing activities			(186,527	)		(204,032	)		17,505
Cash flows (used for) provided by financing activities			(21,533	)		(75,039	)		53,506
	Net cash flows	$	216,927		$	103,680		$	113,247

        Cash provided by operating activities totaled $424,987, compared to $382,751 in the prior year. The increase was primarily due to an increase in net income of $41,272 excluding the non-cash goodwill impairment charge of $108,500 in fiscal 2009. There was also a $29,718 increase in cash used for working capital (defined as net receivables plus net inventories less accounts payable less contract advances and allowances) due primarily to increasing sales driving higher accounts receivable balances. The change in working capital was offset by the cash generated from deferred and accrued tax balance changes of $11,507 and increased compensation accruals of $16,455.

        Cash used for investing activities decreased to $186,527 compared to $204,032 in the prior year primarily as a result of the acquisition of Swales for $101,195 during fiscal 2008, partially offset by the acquisition of Eagle in fiscal 2009 and a $10,772 increase in capital expenditures to expand operations primarily within ATK Space Systems and Corporate.

        Cash used for financing activities totaled $21,533, a decrease of $53,506 compared to $75,039 provided in the prior year. The decrease was driven by a $68,459 decrease in cash paid for the repurchase of treasury shares and a reduction in proceeds of $8,898 from employee compensation plans due to a reduction in stock options exercised.

        ATK expects its level of capital expenditures to increase in the future to maintain and expand its production facilities.

        ATK typically generates cash flows from operating activities in excess of its commitments. ATK has several opportunities for capital deployment, which may include debt repayments, stock repurchases, capital expenditures, funding acquisitions, and other alternatives.

Fiscal 2008

		Years Ended March 31
		2008			2007			Change
Cash flows provided by operating activities		$	382,751		$	44,468		$	338,283
Cash flows used for investing activities			(204,032	)		(80,483	)		(123,549	)
Cash flows (used for) provided by financing activities			(75,039	)		43,018			(118,057	)
	Net cash flows	$	103,680		$	7,003		$	96,677

        Cash provided by operating activities totaled $382,751, compared to $44,468 in the prior year. The increase was primarily due to a decrease in pension contributions of $402,905 and an increase in net income of $38,219 over the prior year period.

        These improvements were partially offset by an increase in cash paid for taxes of $87,372 primarily as a result of the funding of the pension plan during fiscal 2007 and timing of the related cash tax benefits. There was also a $4,932 increase in cash used for working capital (defined as net receivables plus net inventories less accounts payable less contract advances and allowances) due to liquidation of

49

contract advances received in the prior year and increasing sales driving higher accounts receivable balances, offset by higher accounts payable in connection with higher sales and timing of payment to vendors.

        Cash used for investing activities totaled $204,032 compared to $80,483 in the prior year primarily as a result of the acquisition of Swales Aerospace for $101,195 during fiscal 2008, as discussed above, and a $19,623 increase in capital expenditures to expand operations primarily within ATK Mission Systems and ATK Armament Systems, as well as increased information systems costs.

        Cash used for financing activities totaled $75,039, compared to $43,018 provided in the prior year. The use of cash was driven by the absence of debt issuance while the prior year included an issuance of $300,000 of 2.75% Convertible Senior Subordinated Notes due 2011, and a new Term A loan of $275,000 in connection with an amended and restated credit agreement entered in March 2007 partially offset by the corresponding extinguishment of the principal of the existing Term A Loan of $222,750 and scheduled payment made in fiscal 2007 of $20,250.

        These items were partially offset by:

•

a $107,959 decrease in cash paid for the repurchase of ATK common stock,

•

the purchase of call options for $50,850, which were offset by the sale of warrants for $23,220, in connection with ATK's debt issuance in the prior year, as discussed below,

•

no cash overdrafts compared to a decrease in the prior year of $63,036 due to the timing of payments, and

a $9,824 decrease in payments made for debt issuance costs.

        ATK expects its level of capital expenditures to increase in the future to maintain and expand its production facilities.

        ATK typically generates cash flows from operating activities in excess of its commitments. ATK has several opportunities for capital deployment, which may include debt repayments, stock repurchases, capital expenditures, funding acquisitions, and other alternatives.

Liquidity and Capital Resources

        ATK's principal sources of liquidity continue to be its cash and cash equivalents currently on-hand, cash generated by operations and borrowings under credit facilities. Based on ATK's current financial condition, management believes that ATK's cash position, combined with anticipated generation of cash flows and the availability of funding, if needed, under ATK's revolving credit facilities, as well as future sources of funding, including, additional bank financing and debt markets, will be adequate to fund future growth as well as to service ATK's currently anticipated long-term debt and pension obligations, make capital expenditures, and fund any share repurchases over the next 12 months. As discussed further below, at March 31, 2009, the Company's $500 million Revolving Credit Facility had no borrowings against it, and amounts available under the Facility (net of outstanding letters of credit) were $346 million. It is currently expected that there will be no borrowings against it at March 31, 2010. Consistent with historical trends, ATK anticipates using the revolver from time to time during the first half of fiscal 2010 but expects to have any balance paid off by the end of the fiscal year given that the Company's cash flow is stronger in the second half of the year. In the event that the $280,000 aggregate principal amount of 2.75% Convertible Senior Subordinated Notes would be put to (or called by) ATK in August 2009, the Company would expect to utilize the revolver to a greater extent than in the past; however, the Company would still anticipate that the balance will be paid off by March 31, 2010.

Less current portion			293,679		—
Long-term debt		$	1,160,703	$	1,455,000

        In March 2007, ATK entered into an amended and restated Senior Credit Facility dated March 29, 2007 (the "Senior Credit Facility"), which is comprised of a Term A Loan of $275,000 and a $500,000 Revolving Credit Facility, both of which mature in 2012. The Term A Loan is subject to quarterly principal payments of $0 in the year ending March 31, 2009; $3,438 in the years ending March 31, 2010 and 2011; and $6,875 in the year ending March 31, 2012; with the remaining balance due on March 29, 2012. Substantially all domestic, tangible and intangible assets of ATK and its subsidiaries are pledged as collateral under the Senior Credit Facility. Borrowings under the Senior Credit Facility bear interest at a rate equal to the sum of a base rate (currently equal to the bank's prime rate) or a Eurodollar rate plus an applicable margin, which is based on ATK's senior secured credit ratings. The weighted average interest rate for the Term A Loan was 1.40% at March 31, 2009. The annual commitment fee in effect on the unused portion of ATK's Revolving Credit Facility was 0.20% at March 31, 2009. As of March 31, 2009, ATK had no borrowings against its $500,000 revolving credit facility and had outstanding letters of credit of $153,570, which reduced amounts available on the revolving facility to $346,430. ATK's weighted average interest rate on short-term borrowings was 4.98% during fiscal 2009 and 6.60% during fiscal 2008. Debt issuance costs of approximately $3,100 are being amortized over the term of the Senior Credit Facility.

        During March 2006, ATK terminated its remaining $100,000 notional amount interest rate swap, resulting in a cash payout of $2,496. This amount was included in accumulated other comprehensive loss and was amortized to interest expense, at a rate of $936 per year, through November 2008, the original maturity date of the swap.

        In fiscal 2007, ATK issued $300,000 aggregate principal amount of 2.75% Convertible Senior Subordinated Notes (the "2.75% Convertible Notes due 2011") that mature on September 15, 2011. Interest on these notes is payable on March 15 and September 15 of each year. Holders may convert their notes at a conversion rate of 10.3617 shares of ATK's common stock per $1 principal amount of these notes (a conversion price of $96.51 per share) under the following circumstances: (1) when, if the last reported sale price of ATK stock is greater than or equal to 130% of the conversion price, or $125.46, for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter; (2) upon the occurrence of certain corporate transactions; or (3) during the last month prior to maturity. ATK is required to satisfy 100% of the principal amount of these notes solely in cash, with any amounts above the principal amount to be satisfied in cash, common stock, or a combination of cash and common stock, at the sole election of ATK. If certain fundamental changes occur prior to maturity, ATK will in certain circumstances increase the conversion

51

rate by a number of additional shares of common stock or, in lieu thereof, ATK may in certain circumstances elect to adjust the conversion rate and related conversion obligation so that these notes are convertible into shares of the acquiring or surviving company. These contingently issuable shares increased the number of ATK's diluted shares outstanding during fiscal 2008 by 259,237 shares because ATK's average stock price exceeded the conversion price during the year. There was no impact on the diluted shares outstanding for fiscal 2009 or 2007 because ATK's average stock price during those years was below the conversion price. Debt issuance costs of approximately $7,200 are being amortized to interest expense over five years. Approximately $100,000 of the net proceeds from the issuance of these notes was used to concurrently repurchase 1,285,200 shares of ATK's common stock.

        In connection with the issuance of the 2.75% Convertible Notes due 2011, ATK purchased, at a cost of $50,850, call options (the "Call Options") on its common stock. The Call Options, which become exercisable upon conversion of the related convertible notes, allow ATK to purchase approximately 3.1 million shares of ATK's common stock and/or cash from the counterparty at an amount equal to the amount of common stock and/or cash related to the excess conversion value that ATK would pay to the holders of the related convertible notes upon conversion. For income tax reporting purposes, the related convertible notes and the Call Options are integrated. This creates an original issue discount for income tax reporting purposes, and therefore the cost of the Call Options will be accounted for as interest expense over the term of the convertible notes for income tax reporting purposes. The associated income tax benefits will be recognized in the period in which the deduction is taken for income tax reporting purposes as an increase in additional paid-in capital (APIC) in stockholders' equity. In addition, ATK sold warrants (the "Warrants") to issue approximately 3.3 million shares of ATK's common stock at an exercise price of $116.75 per share. The proceeds from the sale of the Warrants totaled $23,220. In accordance with SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities ("SFAS No. 133"), and Emerging Issues Task Force ("EITF") Issue No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock, ATK recorded the net cost of the Call Options and the Warrants of $27,630 in APIC and will not recognize any changes in the fair value of the instruments. On a combined basis, the Call Options and the Warrants are intended to reduce the potential dilution of ATK's common stock in the event that the 2.75% Convertible Notes due 2011 are converted by effectively increasing the conversion price of these notes from $96.51 to $116.75. The Call Options are anti-dilutive and are therefore excluded from the calculation of diluted shares outstanding. The Warrants will result in additional diluted shares outstanding if ATK's average common stock price exceeds $116.75. The Call Options and the Warrants are separate and legally distinct instruments that bind ATK and the counterparty and have no binding effect on the holders of the convertible notes.

        In fiscal 2006, ATK issued $400,000 aggregate principal amount of 6.75% Senior Subordinated Notes (the "6.75% Notes") that mature on April 1, 2016. These notes are general unsecured obligations. Interest on these notes accrues at a rate of 6.75% per annum and is payable semi-annually on April 1 and October 1 of each year. ATK has the right to redeem some or all of these notes from time to time on or after April 1, 2011, at specified redemption prices. Prior to April 1, 2011, ATK may redeem some or all of these notes at a price equal to 100% of their principal amount plus accrued and unpaid interest to the date of redemption and a specified make-whole premium. In addition, prior to April 1, 2009, ATK may redeem up to 35% of the aggregate principal amount of these notes, at a price equal to 106.75% of their principal amount plus accrued and unpaid interest to the date of redemption, with the proceeds of certain equity offerings. Debt issuance costs related to these notes of $7,700 are being amortized to interest expense over ten years.

        In fiscal 2005, ATK issued $200,000 aggregate principal amount of 3.00% Convertible Senior Subordinated Notes (the "3.00% Convertible Notes") that mature on August 15, 2024. Interest on these notes is payable on February 15 and August 15 of each year. Starting with the period beginning on August 20, 2014 and ending on February 14, 2015, and for each of the six-month periods thereafter

52

beginning on February 15, 2015, ATK will pay contingent interest during the applicable interest period if the average trading price of these notes on the five trading days ending on the third day immediately preceding the first day of the applicable interest period equals or exceeds 120% of the principal amount of these notes. The contingent interest payable per note within any applicable interest period will equal an annual rate of 0.30% of the average trading price of a note during the measuring period. The contingent interest feature is treated as an embedded derivative under SFAS No. 133, and the fair value of this feature was insignificant at March 31, 2008 and 2007. ATK may redeem some or all of these notes in cash at any time on or after August 20, 2014. Holders of these notes may require ATK to repurchase in cash some or all of these notes on August 15, 2014 and August 15, 2019. Holders may also convert their 3.00% Convertible Notes at a conversion rate of 12.5392 shares of ATK's common stock per $1 principal amount of these notes (a conversion price of $79.75) under the following circumstances: (1) when, during any fiscal quarter, the last reported sale price of ATK stock is greater than or equal to 130% of the conversion price, or $103.68, for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter; (2) if ATK calls these notes for redemption; or (3) upon the occurrence of certain corporate transactions. The stock price condition was satisfied during ATK's second fiscal quarter ended September 30, 2007 and, accordingly, the unamortized debt issuance costs, which were previously being amortized through the first redemption date of these notes, of approximately $3,200 were written off. The stock price condition was met during the quarter ended September 28, 2008 and $547 of these notes were converted during ATK's third fiscal quarter ended December 28, 2008 (settlement occurred in January 2009). The stock price condition was not satisfied during ATK's fourth fiscal quarter of 2009; therefore the remaining principal amount of $199,453 as of March 31, 2009, was classified as long-term debt. In fiscal 2005, ATK amended the indenture to require ATK to satisfy 100% of the principal amount of these notes solely in cash, with any amounts above the principal amount to be satisfied in cash, common stock, or a combination of cash and common stock, at the sole election of ATK. If certain fundamental changes occur on or prior to August 15, 2014, ATK will in certain circumstances increase the conversion rate by a number of additional shares of common stock or, in lieu thereof, ATK may in certain circumstances elect to adjust the conversion rate and related conversion obligation so that these notes are convertible into shares of the acquiring or surviving company. These contingently issuable shares increased the number of ATK's diluted shares outstanding for fiscal 2009, fiscal 2008, and fiscal 2007 by 326,363, 608,324, and 19,040 shares, respectively, because ATK's average stock price exceeded the conversion price during those years.

        In fiscal 2004, ATK issued $280,000 aggregate principal amount of 2.75% Convertible Senior Subordinated Notes (the "2.75% Convertible Notes due 2024") that mature on February 15, 2024. Interest on these notes is payable on February 15 and August 15 of each year. Beginning with the period beginning on August 20, 2009 and ending on February 14, 2010, and for each of the six-month periods thereafter beginning on February 15, 2010, ATK will pay contingent interest during the applicable interest period if the average trading price of these notes on the five trading days ending on the third day immediately preceding the first day of the applicable interest period equals or exceeds 120% of the principal amount of these notes. The contingent interest payable per note within any applicable interest period will equal an annual rate of 0.30% of the average trading price of a note during the measuring period. The contingent interest feature is treated as an embedded derivative under SFAS No. 133, and the fair value of this feature was insignificant at March 31, 2009 and 2008. ATK may redeem some or all of these notes in cash at any time on or after August 20, 2009. Holders of these notes may require ATK to repurchase in cash some or all of these notes on August 15, 2009, February 15, 2014, or February 15, 2019. Holders may also convert these notes into shares of ATK's common stock at a conversion rate of 12.5843 shares per $1 principal amount of the notes (a conversion price of $79.46) under the following circumstances: (1) when, during any fiscal quarter, the last reported sale price of ATK stock is greater than or equal to 130% of the conversion price, or $103.30, for at least 20 trading days in the period of 30 consecutive trading days ending on the last

53

trading day of the preceding fiscal quarter; (2) if ATK calls these notes for redemption; or (3) upon the occurrence of certain corporate transactions. The stock price condition was satisfied during ATK's second fiscal quarter ended September 30, 2007 and, accordingly, the unamortized debt issuance costs, which were previously being amortized through the first redemption date of these notes, of approximately $2,400 were written off. The stock price condition was met during the quarter ended September 28, 2008 and $71 of these notes were converted during ATK's third fiscal quarter ended December 28, 2008 ($10 settled in November 2008 and the remaining $61 settled in January 2009). The stock price condition was not satisfied during ATK's fourth fiscal quarter of 2009. Because the remaining notes can be put to ATK at the option of each holder in August 2009, the remaining principal amount of $279,929 is classified as current as of March 31, 2009. In fiscal 2005, ATK amended the indenture to require ATK to satisfy 100% of the principal amount of these notes solely in cash, with any amounts above the principal amount to be satisfied in cash, common stock, or a combination of cash and common stock, at the sole election of ATK. These contingently issuable shares increased the number of ATK's diluted shares outstanding for fiscal 2009, fiscal 2008, and fiscal 2007 by 470,669, 864,282, and 39,283 shares, respectively, because ATK's average stock price exceeded the conversion price during those years.

        The 3.00% Convertible Notes, the 2.75% Convertible Notes due 2024, the 2.75% Convertible Notes due 2011, and the 6.75% Notes rank equal in right of payment with each other and all of ATK's future senior subordinated indebtedness and are subordinated in right of payment to all existing and future senior indebtedness, including the Senior Credit Facility. The outstanding notes are guaranteed on an unsecured basis, jointly and severally and fully and unconditionally, by substantially all of ATK's domestic subsidiaries. Subsidiaries of ATK other than the subsidiary guarantors are minor. All of these guarantor subsidiaries are 100% owned by ATK. These guarantees are senior subordinated obligations of the applicable subsidiary guarantors.

        The scheduled minimum loan payments on outstanding long-term debt are as follows:

Fiscal 2010	$	293,679
Fiscal 2011		13,750
Fiscal 2012		547,500
Fiscal 2013		—
Fiscal 2014		—
Thereafter		599,453
Total	$	1,454,382

        Although the 2.75% Convertible Notes due 2024 do not contractually mature until 2024, these notes are classified as current on the consolidated balance sheet and within the "Fiscal 2010" category above because the notes can be put to ATK at the option of each holder in August 2009.

        ATK's total debt (current portion of debt and long-term debt) as a percentage of total capitalization (total debt and stockholders' equity) was 70% as of March 31, 2009 and 66% as of March 31, 2008.

        ATK's Senior Credit Facility and the indentures governing the 6.75% Notes, the 2.75% Convertible Notes due 2011, the 2.75% Convertible Notes due 2024, and the 3.00% Convertible Notes impose restrictions on ATK, including limitations on its ability to incur additional debt, enter into capital leases, grant liens, pay dividends and make certain other payments, sell assets, or merge or consolidate with or into another entity. In addition, the Senior Credit Facility limits ATK's ability to enter into sale-and-leaseback transactions. The Senior Credit Facility also requires that ATK meet and maintain specified financial ratios, including a minimum interest coverage ratio and a maximum consolidated leverage ratio. ATK's ability to comply with these covenants and to meet and maintain the financial ratios may be affected by events beyond its control. Borrowings under the Senior Credit Facility are

54

subject to compliance with these covenants. As of March 31, 2009, ATK was in compliance with the financial covenants.

        As of March 31, 2009, Moody's Investors Service ("Moody's") had assigned ATK an issuer rating of Ba3, Standard & Poor's Ratings Services ("S&P") had assigned ATK a BB corporate credit rating and Fitch Ratings ("Fitch") had assigned ATK an issuer rating of BB.

        ATK has limited payment requirements under the Senior Credit Facility over the next few years. ATK's other debt service requirements consist principally of interest expense on its long-term debt. As discussed above, additional cash may be required to repurchase or convert any or all of the convertible notes under certain circumstances. ATK's short-term cash requirements for operations are expected to consist mainly of capital expenditures to maintain and expand production facilities and working capital requirements.

Interest Rate Swaps

        ATK may use interest rate swaps to hedge forecasted interest payments and the risk associated with changing interest rates of long-term debt. ATK did not have any outstanding interest rate swaps as of March 31, 2009 or 2008.

Commodity Forward Contracts

        ATK periodically uses derivatives to hedge certain commodity price risks. ATK entered into forward contracts for lead during fiscal 2009. During fiscal 2008, ATK had no such forward contracts. ATK did have such contracts for copper, zinc, and lead during fiscal 2007. The contracts essentially established a fixed price for the underlying commodities and were designated and qualified as effective cash flow hedges of purchases of these commodities. Ineffectiveness was calculated as the amount by which the change in the fair value of the derivatives exceeded the change in the fair value of the anticipated commodity purchases. The fair value of these contracts was recorded as a current asset and the effective portion was reflected in accumulated other comprehensive (loss) income (OCI) in the financial statements. The gains on these contracts were recorded in cost of sales as the commodities were purchased. The following table summarizes the pre-tax activity in OCI related to these forward contracts during fiscal 2009, 2008, and 2007:

	Years Ended March 31
	2009			2008		2007
Beginning of period unrealized gain in accumulated OCI	$	—		$	—	$	15,162
(Decrease) increase in fair value of derivatives		(1,837	)		—		14,446
Losses (gains) reclassified from OCI, increasing (offsetting) the price paid to suppliers		1,837			—		(29,608	)
End of period unrealized gain in accumulated OCI	$	—		$	—	$	—

        The amount of ineffectiveness recognized in earnings for these contracts was $0 during fiscal 2009 and 2008 and $(241) in fiscal 2007.

Share Repurchases

        On January 31, 2006, ATK's Board of Directors authorized the repurchase of 5,000,000 shares through January 31, 2008. In February and March 2006, ATK repurchased 1,315,104 shares for $100,000. During fiscal 2007, ATK repurchased 2,585,200 shares for $201,880. During fiscal 2008, ATK repurchased 942,200 shares for $100,068. The Board's authorization expired on January 31, 2008. On August 5, 2008, ATK's Board authorized the repurchase of up to an additional 5,000,000 shares. The Board has determined that the repurchase program will serve primarily to offset dilution from the

55

Company's employee and director benefit compensation programs, but it may also be used for other corporate purposes, as determined by the Board. During fiscal 2009, ATK repurchased 299,956 shares for $31,609. As of March 31, 2009, there were 4,700,044 remaining shares authorized to be repurchased.

        Any additional authorized repurchases would be subject to market conditions and ATK's compliance with its debt covenants. ATK's 6.75% Senior Subordinated Notes limit the aggregate sum of dividends, share repurchases, and other designated restricted payments to an amount based on ATK's net income, stock issuance proceeds, and certain other items, less restricted payments made, since April 1, 2001. As of March 31, 2009, this limit was approximately $352,000. As of March 31, 2009, the Senior Credit Facility allows ATK to make unlimited "restricted payments" (as defined in the credit agreement), which among other items, would allow payments for future stock repurchases, as long as ATK maintains certain senior debt limits, with an annual limit, when those debt limits are not met, of $50,000 plus proceeds of any equity issuances plus 50% of net income since March 29, 2007.

Contractual Obligations and Commercial Commitments

        The following table summarizes ATK's contractual obligations and commercial commitments as of March 31, 2009:

		Payments due by period
Contractual obligations:		Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Long-term debt		$	1,454,382	$	293,679	$	561,250	$	—	$	599,453
Interest on debt(1)			322,674		40,636		102,983		65,967		113,088
Operating leases			313,078		66,098		106,657		89,237		51,086
Environmental remediation costs, net			24,976		2,703		703		4,030		17,540
Pension and other PRB plan contributions			1,763,047		65,795		436,793		479,567		780,892
	Total contractual obligations	$	3,878,157	$	468,911	$	1,208,386	$	638,801	$	1,562,059

	Commitment Expiration by period
Other commercial commitments:	Total		Within 1 year		1-3 years
Letters of credit	$	153,570	$	35,190	$	118,380

(1)

Includes interest on variable rate debt calculated based on interest rates at March 31, 2009. Variable rate debt was approximately 19% of ATK's total debt at March 31, 2009.

        The total liability for uncertain tax positions under FASB Interpretation No. 48 ("FIN 48"), Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109, at March 31, 2009 was approximately $25,828. Of this amount, $25,570 is not expected to be paid within 12 months and is therefore classified within other long-term liabilities. ATK is not able to provide a reasonably reliable estimate of the timing of future payments relating to the non-current FIN 48 obligations.

        Pension plan contributions are an estimate of ATK's minimum funding requirements through fiscal 2019 to provide pension benefits for employees based on expected actuarial estimated service accruals through fiscal 2019 pursuant to the Employee Retirement Income Security Act, although ATK may make additional discretionary contributions. These estimates may change significantly depending on the actual rate of return on plan assets, discount rates, discretionary pension contributions, and regulations. A substantial portion of ATK's Plan contributions are recoverable from the U.S. Government as

56

allowable indirect contract costs at amounts generally equal to the pension plan contributions, although not necessarily in the same year the contribution is made.

Off-Balance Sheet Arrangements

        In connection with the issuance of the 2.75% Convertible Notes due 2011, ATK entered into call option and warrant transactions. The convertible note call option and warrant transactions are designed to increase the effective conversion price per share of ATK's common stock from $96.51 to $116.75 and, therefore, mitigate the potential dilution upon conversion of the 2.75% Convertible Notes due 2011 at the time of conversion. The convertible note call option and warrant transactions have been recorded at cost within stockholders' equity in the consolidated financial statements in accordance with EITF No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock and EITF No. 01-6, The Meaning of "Indexed to a Company's Own Stock." See further discussion under the heading "Debt" above.

Contingencies

        Litigation.    From time to time, ATK is subject to various legal proceedings, including lawsuits, which arise out of, and are incidental to, the conduct of ATK's business. ATK does not consider any of such proceedings that are currently pending, individually or in the aggregate, to be material to its business or likely to result in a material adverse effect on its future operating results, financial condition, or cash flows.

        On or about April 10, 2006, a former ATK employee filed a qui tam complaint in federal court in Utah alleging that ATK knowingly submitted claims for payment to the U.S. government for defective LUU series illuminating flares that failed to conform to certain safety specifications and falsely certified compliance with those specifications. The lawsuit was initially filed under seal. ATK was first informed of the lawsuit by the United States Department of Justice (DOJ) on March 13, 2007. Thereafter, the DOJ intervened in the qui tam action and filed an amended complaint on November 2, 2007. On May 29, 2008, ATK filed its answer to the complaint. The DOJ subsequently filed a motion to strike the affirmative defenses set forth in ATK's answer. On July 14, 2008, ATK filed its opposition to the motion to strike. On October 16, 2008, the court granted the motion in part and denied it in part. Discovery is underway in the case.

        ATK denies any allegations of improper conduct. Based on what is known to ATK about the subject matter of the complaint, ATK does not believe that it has violated any law or regulation and believes it has valid defenses to all allegations of improper conduct. Although it is not possible at this time to predict the outcome of the litigation, ATK believes, based on all available information, that the outcome will not have a material adverse effect on its operating results, financial condition or cash flows. Some potential, however, does remain for an adverse judgment that could be material to ATK's financial position, results of operations, or cash flows. As a result of the uncertainty regarding the outcome of this matter, no provision has been made in the financial statements with respect to this contingent liability.

        Environmental Liabilities.    ATK's operations and ownership or use of real property are subject to a number of federal, state, and local environmental laws and regulations, including those for discharge of hazardous materials, remediation of contaminated sites, and restoration of damage to the environment. At certain sites that ATK owns or operates or formerly owned or operated, there is known or potential contamination that ATK is required to investigate or remediate. ATK could incur substantial costs, including remediation costs, resource restoration costs, fines, and penalties, or third party property damage or personal injury claims, as a result of liabilities associated with past practices or violations of environmental laws or non-compliance with environmental permits.

57

        The liability for environmental remediation represents management's best estimate of the present value of the probable and reasonably estimable costs related to known remediation obligations. The receivable represents the present value of the amount that ATK expects to recover, as discussed below. Both the liability and receivable have been discounted to reflect the present value of the expected future cash flows, using a discount rate of 1.75% and 2.5% as of March 31, 2009 and 2008, respectively. ATK's discount rate is calculated using the 20-year Treasury constant maturities rate, net of an estimated inflationary factor of 1.9%, rounded to the nearest quarter percent. The following is a summary of the amounts recorded for environmental remediation:

	March 31, 2009						March 31, 2008
	Liability			Receivable			Liability			Receivable
Amounts (payable) receivable	$	(62,080	)	$	37,104		$	(64,204	)	$	39,253
Unamortized discount		5,798			(2,900	)		7,831			(3,811	)
Present value amounts (payable) receivable	$	(56,282	)	$	34,204		$	(56,373	)	$	35,442

        As of March 31, 2009, the estimated discounted range of reasonably possible costs of environmental remediation was $56,282 to $85,836.

        ATK expects that a portion of its environmental compliance and remediation costs will be recoverable under U.S. Government contracts. Some of the remediation costs that are not recoverable from the U.S. Government that are associated with facilities purchased in a business acquisition may be covered by various indemnification agreements, as described below.

•

As part of its acquisition of the Hercules Aerospace Company in fiscal 1995, ATK assumed responsibility for environmental compliance at the facilities acquired from Hercules (the "Hercules Facilities"). ATK believes that a portion of the compliance and remediation costs associated with the Hercules Facilities will be recoverable under U.S. Government contracts, and that those environmental remediation costs not recoverable under these contracts will be covered by Hercules Incorporated, a subsidiary of Ashland Inc., (Hercules) under environmental agreements entered into in connection with the Hercules acquisition. Under these agreements, Hercules has agreed to indemnify ATK for environmental conditions relating to releases or hazardous waste activities occurring prior to ATK's purchase of the Hercules Facilities; fines relating to pre-acquisition environmental compliance; and environmental claims arising out of breaches of Hercules' representations and warranties. Hercules is not required to indemnify ATK for any individual claims below $50. Hercules is obligated to indemnify ATK for the lowest cost response of remediation required at the facility that is acceptable to the applicable regulatory agencies. ATK is not responsible for conducting any remedial activities with respect to the Kenvil, NJ facility or the Clearwater, FL facility. In accordance with its agreement with Hercules, ATK notified Hercules of all known contamination on non-federal lands on or before March 31, 2000, and on federal lands on or before March 31, 2005.

•

ATK generally assumed responsibility for environmental compliance at the Thiokol Facilities acquired from Alcoa Inc. ("Alcoa") in fiscal 2002. While ATK expects that a portion of the compliance and remediation costs associated with the acquired Thiokol Facilities will be recoverable under U.S. Government contracts, ATK has recorded an accrual to cover those environmental remediation costs at these facilities that will not be recovered through U.S. Government contracts. In accordance with its agreement with Alcoa, ATK notified Alcoa of all known environmental remediation issues as of January 30, 2004. Of these known issues, ATK is responsible for any costs not recovered through U.S. Government contracts at Thiokol Facilities up to $29,000, ATK and Alcoa have agreed to split evenly any amounts between $29,000 and $49,000, and ATK is responsible for any payments in excess of $49,000.

58

•

With respect to the commercial products business' facilities purchased from Blount in fiscal 2002, Blount has agreed to indemnify ATK for certain compliance and remediation liabilities, to the extent those liabilities are related to pre-closing environmental conditions at or related to these facilities. Some other remediation costs are expected to be paid directly by a third party pursuant to an existing indemnification agreement with Blount. Blount's indemnification obligations relating to environmental matters, which extended through December 7, 2006, are capped at $30,000, less any other indemnification payments made for breaches of representations and warranties. The third party's obligations, which extended through November 4, 2007, are capped at approximately $125,000, less payments previously made.

        ATK cannot ensure that the U.S. Government, Hercules, Alcoa, Blount, or other third parties will reimburse it for any particular environmental costs or reimburse ATK in a timely manner or that any claims for indemnification will not be disputed. U.S. Government reimbursements for cleanups are financed out of a particular agency's operating budget and the ability of a particular governmental agency to make timely reimbursements for cleanup costs will be subject to national budgetary constraints. ATK's failure to obtain full or timely reimbursement from the U.S. Government, Hercules, Alcoa, Blount, or other third parties could have a material adverse effect on its operating results, financial condition, or cash flows. While ATK has environmental management programs in place to mitigate these risks, and environmental laws and regulations have not had a material adverse effect on ATK's operating results, financial condition, or cash flows in the past, it is difficult to predict whether they will have a material impact in the future.

        At March 31, 2009, the aggregate undiscounted amounts payable for environmental remediation costs, net of expected recoveries, are estimated to be:

Fiscal 2010	$	2,703
Fiscal 2011		372
Fiscal 2012		331
Fiscal 2013		2,287
Fiscal 2014		1,743
Thereafter		17,540
Total	$	24,976

        There were no material insurance recoveries related to environmental remediation during fiscal 2009, 2008, or 2007.

        Factors that could significantly change the estimates described in this section on environmental liabilities include:

•

the adoption, implementation, and interpretation of new laws, regulations, or cleanup standards,

•

advances in technologies,

•

outcomes of negotiations or litigation with regulatory authorities and other parties,

•

additional information about the ultimate remedy selected at new and existing sites,

•

adjustment of ATK's share of the cost of such remedies,

•

changes in the extent and type of site utilization,

•

the discovery of new contamination,

•

the number of parties found liable at each site and their ability to pay,

•

more current estimates of liabilities for these contingencies, or

59

•

liabilities associated with resource restoration as a result of contamination from past practices.

New Accounting Pronouncements

        See Note 1 to the consolidated financial statements in Item 8 of this report for discussion of new accounting pronouncements.

Inflation

        In management's opinion, inflation has not had a significant impact upon the results of ATK's operations. The selling prices under contracts, the majority of which are long term, generally include estimated costs to be incurred in future periods. These cost projections can generally be negotiated into new buys under fixed-price government contracts, while actual cost increases are recoverable on cost-type contracts.

        ATK, however, has been impacted by increases in the prices of raw materials used in production as well as rising oil and energy costs. The prices of commodity metals, such as lead, zinc, and especially copper, have significantly increased. These price increases generally impact our small-caliber ammunition business. ATK's risk management practices are discussed in Item 7A of this report.

60

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        ATK is exposed to market risk from changes in interest rates. To mitigate the risks from interest rate exposure, ATK occasionally enters into hedging transactions, mainly interest rate swaps, through derivative financial instruments that have been authorized pursuant to corporate policies. ATK uses derivatives to hedge certain interest rate and commodity price risks, but does not use derivative financial instruments for trading or other speculative purposes, and ATK is not a party to leveraged financial instruments. Additional information regarding the financial instruments is contained in Notes 1 and 3 to the consolidated financial statements. ATK's objective in managing exposure to changes in interest rates is to limit the impact of such changes on earnings and cash flow and to lower the overall borrowing costs.

        ATK measures market risk related to holdings of financial instruments based on changes in interest rates utilizing a sensitivity analysis. The sensitivity analysis measures the potential loss in fair values, cash flows, and earnings based on a hypothetical 10% change (increase and decrease) in interest rates. ATK used current market rates on the debt portfolio to perform the sensitivity analysis. Certain items such as lease contracts, insurance contracts, and obligations for pension and other postretirement benefits were not included in the analysis.

        Currently, ATK's primary interest rate exposures relate to variable rate debt. The potential loss in fair values is based on an assumed immediate change in the net present values of interest rate-sensitive exposures resulting from a 10% change in interest rates. The potential loss in cash flows and earnings is based on the change in the net interest income/expense over a one-year period due to the change in rates. Based on ATK's analysis, a 10% change in interest rates would not have a material impact on the fair values or ATK's results of operations or cash flows.

        With respect to ATK's commercial products business, ATK has improved manufacturing efficiencies and has initiated price increases to mitigate the impact of increased commodity costs. ATK will continue to evaluate the need for future price changes in light of these trends, ATK's competitive landscape, and its financial results. If commodity costs continue to increase, and if ATK is unable to offset these increases with ongoing manufacturing efficiencies and price increases, ATK's future results from operations and cash flows would be materially impacted.

        With respect to ATK's firm fixed-price contract to supply the DoD's small-caliber ammunition needs through April 1, 2010, significant increases in commodities can negatively impact operating results. Depending on market conditions, ATK has occasionally entered into futures contracts in order to reduce the impact of metal price fluctuations. The majority of ATK's copper purchases under the small-caliber ammunition contract were hedged through September 30, 2006. Since that time, ATK has purchased a majority of the copper for use in this contract at prevailing market prices. The balance of the copper requirements has been procured, which mitigates the copper risk for the contract ending April 1, 2010. Depending on market conditions, ATK will continue to evaluate commodity hedging as a means to reduce the impact of commodity price fluctuations on the new four-year supply contract, which is expected to continue into 2014. ATK is currently working within the terms of its contracts to mitigate the impact from price increases in metal commodities. The Company believes that the majority of the impact would be mitigated on the new four-year contract by the terms within that contract; however, if copper prices exceed pre-determined levels, ATK Armament Systems' operating results could be adversely impacted.

ITEM 8.    FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Alliant Techsystems Inc.:
Minneapolis, Minnesota

        We have audited the accompanying consolidated balance sheets of Alliant Techsystems Inc. and subsidiaries (the "Company") as of March 31, 2009 and 2008, and the related consolidated statements of income, stockholders' equity, and cash flows for each of the three years in the period ended March 31, 2009. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Alliant Techsystems Inc. and subsidiaries at March 31, 2009 and 2008, and the results of their operations and their cash flows for each of the three years in the period ended March 31, 2009, in conformity with accounting principles generally accepted in the United States of America.

        As discussed in Notes 1, 10, and 11 to the consolidated financial statements, the Company changed its method of accounting for uncertain tax benefits in the year ended March 31, 2008, and for defined benefit pension and postretirement benefit plans in the years ended March 31, 2008 and 2007.

        We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of March 31, 2009, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated May 21, 2009, expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

1. Summary of Significant Accounting Policies

        Nature of Operations.    Alliant Techsystems Inc. (ATK) is a premier aerospace and defense company and leading supplier of products to the U.S. government, allied nations, and prime contractors. ATK is also a major supplier of ammunition and related accessories to law enforcement agencies and commercial customers. ATK is headquartered in Minneapolis, Minnesota and has operating locations throughout the United States, Puerto Rico, and internationally.

        Basis of Presentation.    The consolidated financial statements of ATK include all majority-owned affiliates. All significant intercompany transactions and accounts have been eliminated.

        Fiscal Year.    References in this report to a particular fiscal year refer to the year ended March 31 of that calendar year. ATK's interim quarterly periods are based on 13-week periods and end on Sundays.

        Use of Estimates.    The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect amounts reported therein. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ from those estimates.

Revenue Recognition.

Long-Term Contracts—Sales under long-term contracts are accounted for under the percentage-of-completion method and include cost-plus and fixed-price contracts. Sales under cost-plus contracts are recognized as costs are incurred. Sales under fixed-price contracts are either recognized as the actual cost of work performed relates to the estimate at completion (cost-to-cost) or based on results achieved, which usually coincides with customer acceptance (units-of-delivery).

        Profits expected to be realized on contracts are based on ATK's estimates of total contract sales value and costs at completion. Estimated amounts for contract changes and claims are included in contract sales only when realization is estimated to be probable. Assumptions used for recording sales and earnings are adjusted in the period of change to reflect revisions in contract value and estimated costs. In the period in which it is determined that a loss will be incurred on a contract, the entire amount of the estimated loss is charged to cost of sales.

        Contracts may contain provisions to earn incentive and award fees if specified targets are achieved. Incentive and award fees that can be reasonably estimated and are probable are recorded over the performance period of the contract. Incentive and award fees that cannot be reasonably estimated are recorded when awarded.

Commercial Products—Sales are recognized when persuasive evidence of an arrangement exists, the product has been delivered and legal title and all risks of ownership have been transferred, written contract and sales terms are complete, customer acceptance has occurred, and payment is reasonably assured. Sales are reduced for allowances and price discounts.

        Operating Expenses.    Selling and general and administrative costs are expensed in the year incurred. Research and development costs include costs incurred for experimentation, design testing, and bid and proposal efforts related to products and services and are expensed as incurred unless the costs are related to certain contractual arrangements. Costs that are incurred pursuant to such

67

(Amounts in thousands except share and per share data and unless otherwise indicated)

1. Summary of Significant Accounting Policies (Continued)

contractual arrangements are recorded over the period that revenue is recognized, consistent with ATK's contract accounting policy.

        Environmental Remediation and Compliance.    Costs associated with environmental compliance, restoration, and preventing future contamination that are estimable and probable are accrued and expensed, or capitalized as appropriate. Expected remediation, restoration, and monitoring costs relating to an existing condition caused by past operations, and which do not contribute to current or future revenue generation, are accrued and expensed in the period that such costs become estimable. Liabilities are recognized for remedial and resource restoration activities when they are probable and the cost can be reasonably estimated.

        ATK's engineering, financial, and legal specialists estimate, based on current law and existing technologies, the cost of each environmental liability. Such estimates are based primarily upon the estimated cost of investigation and remediation required and the likelihood that other potentially responsible parties (PRPs) will be able to fulfill their commitments at the sites where ATK may be jointly and severally liable. ATK's estimates for environmental obligations are dependent on, and affected by, the nature and extent of historical information and physical data relating to a contaminated site, the complexity of the site, methods of remediation available, the technology that will be required, the outcome of discussions with regulatory agencies and other PRPs at multi-party sites, the number and financial viability of other PRPs, changes in environmental laws and regulations, future technological developments, and the timing of expenditures; accordingly, such estimates could change materially as ATK periodically evaluates and revises such estimates based on expenditures against established reserves and the availability of additional information.

        Cash Equivalents.    Cash equivalents are all highly liquid temporary cash investments purchased with original maturities of three months or less.

        Marketable Securities.    Investments in a common collective trust that primarily invests in fixed income securities are classified as available-for-sale securities and are recorded at fair value within deferred charges and other non-current assets. Unrealized gains and losses are recorded in other comprehensive (loss) income (OCI). When such investments are sold, the unrealized gains or losses are reversed from OCI and recognized in the consolidated income statement.

        Inventories.    Inventories are stated at the lower of cost or market. Inventoried costs relating to contracts in progress are stated at actual production costs, including factory overhead, initial tooling, and other related costs incurred to date, reduced by amounts associated with recognized sales. Raw materials, work in process, and finished goods are generally determined using the standard costing method.

1. Summary of Significant Accounting Policies (Continued)

        Inventories consist of the following:

	March 31
	2009		2008
Raw materials	$	60,545	$	50,964
Work in process		46,436		55,824
Finished goods		93,050		50,840
Contracts in progress		38,569		48,197
Net inventories	$	238,600	$	205,825

        Progress payments received from customers relating to the uncompleted portions of contracts are offset against unbilled receivable balances or applicable inventories. Any remaining progress payment balances are classified as contract advances. Inventories are shown net of reductions of $0 as of March 31, 2009 and $20,627 as of March 31, 2008 for customer progress payments received on uncompleted portions of contracts.

Accounting for Goodwill—In accordance with SFAS No. 142, Goodwill and Other Intangible Assets ("SFAS No. 142"), ATK tests goodwill and intangible assets with indefinite lives for impairment on an annual basis or upon the occurrence of events that may indicate possible impairment. SFAS 142 requires that goodwill be tested as of the same date every year; ATK's annual testing date is the first day of its fourth fiscal quarter, which was December 29, 2008, for our fiscal 2009 analysis. In accordance with SFAS No. 142, the Company determined that the reporting units for its goodwill impairment review are its operating segments, or components of an operating segment, that constitute a business for which discrete financial information is available, and for which segment management regularly reviews the operating results. Based on this analysis, the Company has identified ten reporting units within its reportable segments as of December 29, 2008.

        SFAS No. 142 prescribes a two-step process for determining goodwill impairment. In the first step, ATK determines the estimated fair value of each reporting unit and compares that estimated fair value to the carrying value of such reporting unit, including goodwill. If the results of the first step indicate that the carrying amount of a reporting unit is higher than its fair value, the second step must be performed. Specifically, SFAS No. 142 prescribes that in the second step, ATK must determine the implied fair value of goodwill in the same manner as if ATK had acquired those reporting units in a business combination. In the second step, the potential impairment is computed by comparing the implied fair value of the reporting unit's goodwill with the carrying amount of goodwill. If the carrying amount of the reporting unit's goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess.

        In the fourth quarter of fiscal 2009, ATK recorded a non-cash goodwill impairment charge of $108,500. See Note 7 for further details.

        Stock-Based Compensation.    ATK's stock-based employee compensation plans, which are described more fully in Note 14, provide for the grant of various types of stock-based incentive awards, including performance awards, restricted stock, and options to purchase common stock. ATK accounts for stock-based compensation under Statement on Financial Accounting Standards (SFAS) 123(R), Share-Based Payments, and related Securities and Exchange Commission (SEC) rules included in Staff Accounting

69

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Amounts in thousands except share and per share data and unless otherwise indicated)

1. Summary of Significant Accounting Policies (Continued)

Bulletin (SAB) No. 107, on a modified prospective basis. Prior to the adoption of SFAS 123(R), ATK accounted for those plans under the recognition and measurement principles of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations.

        The types and mix of stock-based incentive awards are evaluated on an ongoing basis and may vary based on ATK's overall strategy regarding compensation, including consideration of the impact of expensing stock awards on ATK's results of operations subsequent to the adoption of SFAS 123(R).

        Income Taxes.    Provisions for federal and state income taxes are calculated based on reported pre-tax earnings and current tax law. Such provisions differ from the amounts currently receivable or payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. Significant judgment is required in determining income tax provisions and evaluating tax positions. ATK periodically assesses its liabilities and contingencies for all periods that are currently open to examination or have not been effectively settled based on the most current available information. Where it is not more likely than not that ATK's tax position will be sustained, the Company records the entire resulting tax liability and when it is more likely than not of being sustained, the Company records its best estimate of the resulting tax liability. Any applicable interest and penalties related to those positions are also recorded in the consolidated financial statements. To the extent ATK's assessment of the tax outcome of these matters changes, such change in estimate will impact the income tax provision in the period of the change. It is ATK's policy to record any interest and penalties related to income taxes as part of the income tax expense for financial reporting purposes.

        Derivative Instruments and Hedging Activities.    From time to time, ATK uses derivatives, consisting mainly of commodity forward contracts to hedge forecasted purchases of certain commodities, interest rate swaps to hedge forecasted interest payments and the risk associated with changing interest rates of long-term debt, and foreign currency exchange contracts to hedge forecasted transactions denominated in a foreign currency. ATK does not hold or issue derivatives for trading purposes. At the inception of each derivative instrument, ATK documents the relationship between the hedging instrument and the hedged item, as well as its risk-management objectives and strategy for undertaking the hedge transaction. ATK assesses, both at the hedge's inception and on an ongoing basis, whether the derivative instrument is highly effective in offsetting changes in the hedged item. Derivatives are recognized on the balance sheet at fair value. If the derivative is designated as a cash flow hedge, the effective portion of the change in the fair value of the derivative is recorded to accumulated other comprehensive (loss) income (OCI), and recognized in earnings when the hedged item affects earnings.

        Commodity Forward Contracts.    ATK periodically uses derivatives to hedge certain commodity price risks. ATK entered into forward contracts for lead during fiscal 2009. During fiscal 2008, ATK had no such forward contracts. ATK did have such contracts for copper, zinc, and lead during fiscal 2007. The contracts essentially established a fixed price for the underlying commodities and were designated and qualified as effective cash flow hedges of purchases of these commodities. Ineffectiveness was calculated as the amount by which the change in the fair value of the derivatives exceeded the change in the fair value of the anticipated commodity purchases. The fair value of these contracts was recorded as a current asset and the effective portion was reflected in accumulated OCI in the financial statements. The gains on these contracts were recorded in cost of sales as the commodities were

purchased. The following table summarizes the pre-tax activity in OCI related to these forward contracts during fiscal 2009, 2008, and 2007:

	Years Ended March 31

End of period unrealized gain in accumulated OCI	$	—		$	—	$	—

        The amount of ineffectiveness recognized in earnings for these contracts was $0 during fiscal 2009 and $(241) in fiscal 2007.

        Earnings Per Share Data.    Basic earnings per share (EPS) is computed based upon the weighted-average number of common shares outstanding for each period. Diluted EPS is computed based on the weighted average number of common shares and common equivalent shares. Common equivalent shares represent the effect of stock-based awards (see Note 14) and contingently issuable shares related to ATK's Convertible Senior Subordinated Notes (see Note 9) during each period presented, which, if exercised, earned, or converted, would have a dilutive effect on earnings per share. In computing EPS for fiscal 2009, 2008, and 2007, earnings, as reported for each respective period, is divided by (in thousands):

	Years Ended March 31
	2009		2008		2007
Basic EPS shares outstanding		32,730		32,924		33,885
Dilutive effect of stock-based awards		486		552		648
Dilutive effect of contingently issuable shares		797		1,732		58
Diluted EPS shares outstanding		34,013		35,208		34,591
Shares excluded from the calculation of diluted EPS because the option exercise/threshold price was greater than the average market price of the common shares		—		—		34

        Contingently issuable shares related to ATK's 3.00% Convertible Senior Subordinated Notes and 2.75% Convertible Senior Subordinated Notes due 2024, as discussed in Note 9, are included in diluted EPS in fiscal 2009, 2008, and 2007. Contingently issuable shares related to ATK's 2.75% Convertible Senior Subordinated Notes due 2011, as discussed in Note 9, are included in diluted EPS in fiscal 2008 but are not included in diluted EPS in fiscal 2009 or 2007 because ATK's average stock price was below the conversion price of $96.51during those years. The Warrants, as discussed in Note 9, are not included in diluted EPS as ATK's average stock price during fiscal 2009, 2008, and 2007 did not exceed $116.75. The Call Options, also discussed in Note 9, are anti-dilutive and are therefore excluded from the calculation of diluted shares outstanding.

Total accumulated other comprehensive loss	$	(651,652	)	$	(376,636	)

        Fair Value of Nonfinancial Instruments.    The carrying amount of receivables, inventory, accounts payable and accrued liabilities approximates fair value because of the short maturity of these instruments. See Note 2 for additional disclosure regarding fair value of financial instruments.

        Adoption of New Accounting Pronouncements.    In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS No. 161). This statement establishes enhanced disclosures about derivative and hedging activities. ATK adopted SFAS No. 161 at the beginning of the quarter ended March 31, 2009. The adoption of this statement resulted in enhanced disclosures regarding ATK's derivatives and hedging activities. See Note 3 for additional disclosures.

        In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115. SFAS No. 159 permits entities to choose to measure eligible items at fair value at specified election dates and report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date. SFAS No. 159 was effective for ATK on April 1, 2008. ATK did not choose the fair value option; therefore, the adoption did not have a material impact on ATK's financial statements.

1. Summary of Significant Accounting Policies (Continued)

        In September 2006, the FASB issued SFAS No. 158, Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans—an amendment of FASB Statements No. 87, 88, 106, and 132(R), which requires recognition of the overfunded or underfunded status of a defined benefit postretirement plan (other than a multiemployer plan) as an asset or liability in the statement of financial position and requires recognition of changes in the funded status in the year in which the changes occur through comprehensive income. ATK adopted these provisions in fiscal 2007. SFAS No. 158 also requires measurement of the funded status of a plan as of the date of the year-end statement of financial position. ATK adopted the measurement provisions of SFAS No. 158 effective April 1, 2007 using the method which requires measurement of plan assets and benefit obligations as of the beginning of fiscal 2008. See Note 10.

        In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. In January 2008, the FASB deferred the effective date of SFAS No. 157 for certain nonfinancial assets and liabilities to the fiscal year beginning after November 15, 2008 (ATK's fiscal 2010). SFAS No. 157 is effective for financial assets and liabilities for fiscal years beginning after November 15, 2007 (ATK's fiscal 2009). The adoption of the applicable provisions of SFAS No. 157 on April 1, 2008 did not have a material impact on ATK's financial statements. See Note 2 for additional disclosures. On April 1, 2009 ATK adopted the previously deferred provisions of SFAS No. 157 for nonfinancial assets and liabilities recorded at fair value, as required. The adoption did not have a material impact on its financial statements.

        In June 2007, the FASB ratified Emerging Issues Task Force (EITF) Issue No. 07-03, Accounting for Nonrefundable Advance Payments for Goods and Services Received for Use in Future Research and Development Activities (EITF 07-03). EITF 07-03 requires companies to defer nonrefundable advance payments for goods and services and to expense that advance payment as the goods are delivered or services are rendered. If the company does not expect to have the goods delivered or services performed, the advance should be expensed. EITF 07-03 was effective for ATK on April 1, 2008 and the adoption did not have a material impact on ATK's financial statements.

        In September 2006, the FASB issued EITF 06-4, Accounting for Deferred Compensation and Postretirement Benefit Aspects of Endorsement Split-Dollar Life Insurance Arrangements, which requires an employer to recognize a liability for future benefits based on the substantive agreement with the employee. The adoption of EITF 06-4 had no impact on ATK's results of operations but increased total liabilities and decreased retained earnings by $2,387 as of April 1, 2007.

        In June 2006, the FASB issued FASB Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109. FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ATK must determine whether it is "more-likely-than-not" that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. FIN 48 applies to all tax positions related to income taxes subject to FASB Statement No. 109, Accounting for Income Taxes. FIN 48 was applicable for ATK as of April 1, 2007. See Note 11.

1. Summary of Significant Accounting Policies (Continued)

        Accounting Pronouncements Not Yet Adopted.    In December 2007, the FASB issued SFAS No. 160, Non-controlling Interest in Consolidated Financial Statements. This Statement amends Accounting Research Bulletin 51 to establish accounting and reporting standards for the non-controlling (minority) interest in a subsidiary and for the deconsolidation of a subsidiary. It clarifies that a non-controlling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. SFAS No. 160 is effective for fiscal years beginning after December 15, 2008 (ATK's fiscal 2010). ATK does not believe the adoption of SFAS No. 160 will have a material impact on its financial statements.

        In December 2007, the FASB issued SFAS No. 141(R), Business Combinations. This statement replaces SFAS No. 141, Business Combinations. This statement retains the fundamental requirements in SFAS No. 141 that the acquisition method of accounting (which SFAS No. 141 called the purchase method) be used for all business combinations and for an acquirer to be identified for each business combination. This statement also establishes principles and requirements for how the acquirer: a) recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree; b) recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase; and c) determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. SFAS No. 141(R) will apply prospectively to business combinations for which the acquisition date is after fiscal years beginning on or after December 15, 2008 (ATK's fiscal 2010). Adoption is not expected to materially impact the Company's consolidated financial statements when it becomes effective; however, adoption of this statement is expected to have a significant effect on how acquisition transactions subsequent to March 31, 2009 are reflected in the financial statements.

        In May 2008, the Financial Accounting Standards Board (FASB) issued FASB Staff Position (FSP) No. APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement) (FSP No. APB 14-1). This FSP specifies that issuers of such instruments should separately account for the liability and equity components in a manner that will reflect the entity's nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. The provisions of this FSP apply to ATK's $200,000 aggregate principal amount of 3.00% Convertible Notes, the $280,000 aggregate principal amount of 2.75% Convertible Notes due 2024, and the $300,000 aggregate principal amount of 2.75% Convertible Notes due 2011, discussed in Note 9. This FSP is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years (ATK's fiscal 2010), and shall be applied retrospectively to all periods presented. Early adoption is not permitted. The adoption of the FSP will result in an increase to fiscal 2005 through fiscal 2009 non-cash interest expense in the range of $9,300 ($5,600 net of tax or $0.15 diluted EPS impact) to $23,900 ($14,400 net of tax or $0.42 diluted EPS impact) per year. The impact to fiscal 2010 non-cash interest expense is expected to be an increase of approximately $19,900 ($11,900 net of tax or $0.35 diluted EPS impact assuming the March 31, 2009 dilutive share count) with a declining impact in future years.

        In June 2008, the FASB ratified the consensus reached on EITF Issue No. 07-5, Determining Whether an Instrument (or an Embedded Feature) is Indexed to an Entity's Own Stock (EITF No. 07-5). This EITF provides guidance for determining whether an equity-linked financial instrument (or embedded feature) is indexed to an entity's own stock. The EITF applies to any freestanding financial instrument or embedded feature that has all the characteristics of a derivative under paragraphs 6-9 of

74

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Amounts in thousands except share and per share data and unless otherwise indicated)

1. Summary of Significant Accounting Policies (Continued)

SFAS No. 133, for purposes of determining whether that instrument or embedded feature qualifies for the first part of the scope exception under paragraph 11(a) of SFAS 133. The EITF also applies to any freestanding financial instrument that is potentially settled in an entity's own stock, regardless of whether the instrument has all the characteristics of a derivative under paragraphs 6-9 of SFAS No. 133, for purposes of determining whether the instrument is within the scope of EITF No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock, which provides accounting guidance for instruments that are indexed to, and potentially settled in, the issuer's own stock. EITF No. 07-5 is effective for fiscal years beginning after December 15, 2008 and interim period within those fiscal years (ATK's fiscal 2010). The net cost of ATK's warrants and options are classified within equity (as discussed in Note 9) in accordance with SFAS 133 and EITF 00-19. The adoption of EITF 07-5 does not change this conclusion; therefore, ATK does not believe the adoption will have a material impact on its financial statements.

        In December 2008, the FASB issued FSP No. FAS 132(R)-1, Employer's Disclosures about Postretirement Benefit Plan Assets (FSP 132(R)-1). FSP 132(R)-1 amends the plan asset disclosures required under FASB Statement No. 132(R) to provide guidance on an employer's disclosures about plan assets of a defined benefit pension or other postretirement plan. Guidance provided by this FSP relates to disclosures about investment policies and strategies, categories of plan assets, fair value measurements of plan assets, and significant concentrations of risk. FSP 132(R)-1 is effective for fiscal years ending after December 15, 2009 (ATK's fiscal 2010). The adoption will require additional disclosure in ATK's fiscal 2010 financial statements.

2. Fair Value of Financial Instruments

        As discussed in Note 1, ATK adopted the applicable provisions of SFAS No. 157 related to financial instruments on April 1, 2008. SFAS No. 157 clarifies the definition of fair value, prescribes a framework for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value, and expands disclosures about the use of fair value measurements. SFAS No. 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

        The valuation techniques required by SFAS No. 157 are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy:

        Level 1—Quoted prices for identical instruments in active markets.

        Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

        Level 3—Significant inputs to the valuation model are unobservable.

        The following section describes the valuation methodologies used by ATK to measure its financial instruments at fair value.

2. Fair Value of Financial Instruments (Continued)

        Cash equivalents—The estimated fair value of cash equivalents approximates their carrying value due to the short-term maturities of these investments. Accordingly, cash equivalents are classified as Level 1.

        Investments in marketable securities—ATK's investments in marketable securities represent investments held in a common collective trust ("CCT") that primarily invests in fixed income securities as discussed in Note 1. Investments in a collective investment vehicle are valued by multiplying the investee company's net asset value per share with the number of units or shares owned at the valuation date as determined by the investee company. Net asset value per share is determined by the investee company's custodian or fund administrator by deducting from the value of the assets of the investee company all its liabilities and the resulting number is divided by the outstanding number of shares or units. Investments held by the CCT, including collateral invested for securities on loan, are valued on the basis of valuations furnished by a pricing service approved by the CCT's investment manager, which determines valuations using methods based on market transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders, or at fair value as determined in good faith by the CCT's investment manager.

        Derivative financial instruments and hedging activities—In order to manage its exposure to commodity pricing risk, ATK periodically utilizes commodity derivatives, which are considered Level 2 instruments. Commodity derivatives are valued using an income approach based on the present value of the commodity index price less the contract rate multiplied by the notional amount.

        Long-Term Debt—The fair value of the variable-rate long-term debt is calculated based on current market rates for debt of the same risk and maturities. The fair value of the fixed-rate debt is based on market quotes for each issuance.

        The following table presents ATK's assets and liabilities that are measured at fair value on a recurring basis:

		As of March 31, 2009
		Fair Value Measurements Using Inputs Considered as

2. Fair Value of Financial Instruments (Continued)

        The following table presents ATK's assets and liabilities that are not measured at fair value on a recurring basis. The carrying values and estimated fair values were as follows:

	As of March 31, 2009				As of March 31, 2008
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Fixed rate debt	$	1,179,382	$	1,154,304	$	1,180,000	$	1,434,196
Variable rate debt		275,000		254,375		275,000		275,000

3. Derivative Financial Instruments

        On December 29, 2008, ATK adopted SFAS No. 161, as discussed in Note 1, which requires enhanced disclosures regarding an entity's derivative and hedging activities.

        ATK is exposed to market risks arising from adverse changes in:

•

commodity prices affecting the cost of raw materials and energy,

•

interest rates, and

•

foreign exchange risks

        In the normal course of business, these risks are managed through a variety of strategies, including the use of derivative instruments. Commodity forward contracts are periodically used to hedge forecasted purchases of certain commodities, foreign currency exchange contracts are used to hedge forecasted transactions denominated in a foreign currency, and ATK periodically uses interest rate swaps to hedge forecasted interest payments and the risk associated with variable interest rates on long-term debt.

        During fiscal 2009 ATK entered into commodity forward contracts for lead. The contracts essentially established a fixed price for the underlying commodity and were designated and qualified as effective cash flow hedges. At March 31, 2009, ATK had no outstanding contracts and therefore there were no amounts recorded in the consolidated balance sheet related to any such derivative instruments.

        The derivative gains and losses in the consolidated income statements for the quarter ended March 31, 2009 related to commodity forward contracts were as follows:

	Pretax amount of gain (loss) recognized in Other Comprehensive Income (Loss)		Pretax amount of gain (loss) reclassified from Accumulated Other Comprehensive Income (Loss)
	Amount		Location	Amount
Commodity forward contracts	$	656	Cost of sales	$	(23	)

        All derivatives used by ATK in fiscal 2009 were designated as hedging instruments.

4. Acquisitions

        In accordance with SFAS No. 141, Business Combinations, the results of acquired businesses are included in ATK's consolidated financial statements from the date of acquisition. The purchase price for each acquisition is allocated to the acquired assets and liabilities based on fair value. The excess purchase price over estimated fair value of the net assets acquired is recorded as goodwill.

        On March 31, 2009, ATK acquired Eagle Industries (Eagle), a leading manufacturer of high-quality, individual operational nylon gear and equipment for military, homeland security, and law enforcement agencies for $63,000 net of cash acquired, subject to purchase price adjustments expected to be settled in fiscal 2010. The company manufactures more than 5,000 products which include tactical assault vests, load-bearing equipment, weapon transporting gear, holsters, personal gear carriers, and other high quality accessories. ATK believes that the acquisition provides an opportunity to expand its position in the domestic and international tactical accessories markets serving military and law enforcement customers. Headquartered in Fenton, Missouri, Eagle employs approximately 2,300 employees and is included in ATK Armament Systems. The purchase price allocation has not yet been completed pending final valuation of certain acquired assets and liabilities. At March 31, 2009, substantially all of the purchase price was recorded as goodwill. The final purchase price allocation could be significantly different than the estimate currently recorded. A portion of the goodwill generated in this acquisition will be deductible for tax purposes.

        ATK used the purchase method of accounting to account for this acquisition and, accordingly, the results of Eagle are included in ATK's consolidated financial statements at the date of acquisition. The purchase price for the acquisition will be allocated to the acquired assets and liabilities based on estimated fair value. Pro forma information on the results of operations for fiscal 2009 and 2008 as if the acquisition had occurred at the beginning of fiscal 2008 is not being presented because the acquisition is not material to ATK for that purpose.

        On June 8, 2007, ATK acquired Swales Aerospace (Swales), a provider of satellite components and subsystems, small spacecraft and engineering services for NASA, U.S. Department of Defense and commercial satellite customers for $101,195, net of cash acquired. ATK believes that the acquisition strengthened ATK's satellite components, subsystems and small spacecraft portfolios and further increased ATK's position as a supplier to the U.S. Government and industry. ATK also believes the acquisition enhanced ATK's systems engineering as ATK pursues strategic initiatives in space exploration programs. Headquartered in Beltsville, Maryland, Swales employs approximately 626 employees and is included in ATK Space Systems. The purchase price allocation for Swales was completed during fiscal 2008. A portion of the goodwill generated in this acquisition will be deductible for tax purposes. Pro forma information on results of operations for fiscal 2008 and 2007 as if the acquisition had occurred at the beginning of fiscal 2007 are not being presented because the acquisition is not material to ATK for that purpose.

        ATK made no acquisitions during fiscal 2007.

        During fiscal 2003, ATK acquired the assets of Science and Applied Technology, Inc. (included in ATK Mission Systems). The sellers of this acquired business had the ability to earn up to an additional $7,500 of cash consideration if certain pre-specified milestones were attained with respect to one of the contracts acquired. The pre-specified milestones were met in September 2008 and the additional contingent consideration earned pursuant to the purchase agreement resulted in an increase to goodwill.

5. Receivables

        Receivables, including amounts due under long-term contracts (contract receivables), are summarized as follows:

		March 31
		2009			2008
Billed receivables
	U.S. Government contracts	$	203,534		$	200,871
	Commercial and other		145,905			155,061
Unbilled receivables
	U.S. Government contracts		485,511			426,062
	Commercial and other		76,042			25,083
Less allowance for doubtful accounts			(11,449	)		(8,609	)
Net receivables		$	899,543		$	798,468

        Receivable balances are shown net of customer progress payments received of $320,826 as of March 31, 2009 and $316,022 as of March 31, 2008.

        Unbilled receivables represent the balance of recoverable costs and accrued profit, comprised principally of revenue recognized on contracts for which billings have not been presented to the customer because the amounts were earned but not contractually billable as of the balance sheet date. These amounts include expected additional billable general overhead costs and fees on flexibly priced contracts awaiting final rate negotiations, and are expected to be billable and collectible within one year.

        The following is a reconciliation of the changes in ATK's allowance for doubtful accounts during fiscal 2008 and 2009:

Balance at April 1, 2007	$	5,397
Expense		4,049
Write-offs		(938	)
Reversals and other adjustments		101
Balance at March 31, 2008		8,609
Expense		13,347
Write-offs		(10,341	)
Reversals and other adjustments		(166	)
Balance at March 31, 2009	$	11,449

6. Property, Plant, and Equipment

        Property, plant, and equipment is stated at cost and depreciated over estimated useful lives. Machinery and test equipment is depreciated using the double declining balance method at most of ATK's facilities, and using the straight-line method at other ATK facilities. Other depreciable property is depreciated using the straight-line method. Machinery and equipment are depreciated over one to 23 years and buildings and improvements are depreciated over one to 45 years. Depreciation expense was $80,137 in fiscal 2009, $71,511 in fiscal 2008, and $69,380 in fiscal 2007.

6. Property, Plant, and Equipment (Continued)

        ATK reviews property, plant, and equipment for impairment when indicators of potential impairment are present. When such impairment is identified, it is recorded as a loss in that period. During fiscal 2007, ATK recorded an impairment charge of approximately $9,300 related to the termination of an internal information systems project within general and administrative expense.

        Maintenance and repairs are charged to expense as incurred. Major improvements that extend useful lives are capitalized and depreciated. The cost and accumulated depreciation of property, plant and equipment retired or otherwise disposed of are removed from the related accounts, and any residual values are charged or credited to income.

        Property, plant, and equipment consists of the following:

	March 31
	2009			2008
Land	$	33,837		$	33,115
Buildings and improvements		334,837			311,470
Machinery and equipment		826,640			740,773
Property not yet in service		48,703			50,424
Gross property, plant, and equipment		1,244,017			1,135,782
Less accumulated depreciation		(703,976	)		(643,446	)
Net property, plant, and equipment	$	540,041		$	492,336

7. Goodwill and Deferred Charges and Other Non-Current Assets

        In accordance with SFAS No. 142, Goodwill and Other Intangible Assets, ATK tests goodwill and intangible assets with indefinite lives for impairment on an annual basis or upon the occurrence of events that may indicate possible impairment. Goodwill impairment testing under SFAS No. 142 is a two-step process. First, it requires a comparison of the book value of net assets to the fair value of the related operations that have goodwill assigned to them. ATK estimates the fair values of the related operations using discounted cash flows. If the fair value is determined to be less than the carrying value, a potential impairment is indicated and SFAS No. 142 prescribes the approach for determining the impairment amount, if any. SFAS No. 142 requires that goodwill be tested as of the same date every year; ATK's annual testing date is the first day of its fourth fiscal quarter. ATK determined during its fiscal 2009 impairment test that goodwill at Spacecraft Systems was impaired by $108,500. The non-cash goodwill impairment charge was recognized in the fourth quarter of fiscal 2009. The goodwill impairment charge was attributed to changes in future estimated cash flows and the substantial reduction in current market multiples.

Balance at March 31, 2009	$	232,127	$	362,476	$	601,383		$	1,195,986

        The fiscal 2009 acquisitions in ATK Armament Systems primarily related to Eagle and the fiscal 2008 acquisition in ATK Space Systems was Swales, as previously discussed.

        The adjustment within ATK Mission Systems relates to the fiscal 2003 acquisition of assets of Science and Applied Technology, Inc. The sellers of this acquired business were given the ability to earn up to an additional $7,500 of cash consideration if certain pre-specified milestones were attained with respect to one of the contracts acquired. The pre-specified milestones were met in September 2008 and the additional contingent consideration earned pursuant to the purchase agreement resulted in an increase to goodwill.

        Deferred charges and other non-current assets consist of the following:

			March 31

Other non-current assets				47,232			43,280
		Total deferred charges and other non-current assets	$	192,992		$	194,466

        Included in deferred charges and other non-current assets as of March 31, 2009 and 2008 are other intangible assets of $74,504 and $87,973, respectively, which consist primarily of trademarks, patented technology, and brand names that are not being amortized as their estimated useful lives are considered indefinite. During fiscal 2009, ATK began amortizing a tradename over an estimated useful

        ATK provides product warranties, which entail repair or replacement of non-conforming items, in conjunction with sales of certain products. Estimated costs related to warranties are recorded in the period in which the related product sales occur. The warranty liability recorded at each balance sheet date reflects the estimated liability for warranty coverage for products delivered based on historical information and current trends. The following is a reconciliation of the changes in ATK's product warranty liability during fiscal 2008 and 2009:

Less current portion			293,679		—
Long-term debt		$	1,160,703	$	1,455,000

        In March 2007, ATK entered into an amended and restated Senior Credit Facility dated March 29, 2007 (the Senior Credit Facility), which is comprised of a Term A Loan of $275,000 and a $500,000 Revolving Credit Facility, both of which mature in 2012. The Term A Loan is subject to quarterly principal payments of $0 in the year ending March 31, 2009; $3,438 in the years ending March 31, 2010 and 2011; and $6,875 in the year ending March 31, 2012; with the remaining balance due on March 29, 2012. Substantially all domestic, tangible and intangible assets of ATK and its subsidiaries are pledged as collateral under the Senior Credit Facility. Borrowings under the Senior Credit Facility bear interest at a rate equal to the sum of a base rate (currently equal to the bank's prime rate) or a Eurodollar rate plus an applicable margin, which is based on ATK's senior secured credit ratings. The weighted average interest rate for the Term A Loan was 1.40% at March 31, 2009. The annual commitment fee in effect on the unused portion of ATK's Revolving Credit Facility was 0.20% at March 31, 2009. As of March 31, 2009, ATK had no borrowings against its $500,000 revolving credit facility and had outstanding letters of credit of $153,570, which reduced amounts available on the revolving facility to $346,430. ATK's weighted average interest rate on short-term borrowings was 4.98% during fiscal 2009 and 6.60% during fiscal 2008. Debt issuance costs of approximately $3,100 are being amortized over the term of the Senior Credit Facility.

        During March 2006, ATK terminated its remaining $100,000 notional amount interest rate swap, resulting in a cash payout of $2,496. This amount was included in accumulated other comprehensive loss and was amortized to interest expense, at a rate of $936 per year, through November 2008, the original maturity date of the swap.

        In fiscal 2007, ATK issued $300,000 aggregate principal amount of 2.75% Convertible Senior Subordinated Notes (the 2.75% Convertible Notes due 2011) that mature on September 15, 2011. Interest on these notes is payable on March 15 and September 15 of each year. Holders may convert their notes at a conversion rate of 10.3617 shares of ATK's common stock per $1 principal amount of these notes (a conversion price of $96.51 per share) under the following circumstances: (1) when, if the last reported sale price of ATK stock is greater than or equal to 130% of the conversion price, or $125.46, for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter; (2) upon the occurrence of certain corporate transactions;

84

(Amounts in thousands except share and per share data and unless otherwise indicated)

9. Long-Term Debt (Continued)

or (3) during the last month prior to maturity. ATK is required to satisfy 100% of the principal amount of these notes solely in cash, with any amounts above the principal amount to be satisfied in cash, common stock, or a combination of cash and common stock, at the sole election of ATK. If certain fundamental changes occur prior to maturity, ATK will in certain circumstances increase the conversion rate by a number of additional shares of common stock or, in lieu thereof, ATK may in certain circumstances elect to adjust the conversion rate and related conversion obligation so that these notes are convertible into shares of the acquiring or surviving company. These contingently issuable shares increased the number of ATK's diluted shares outstanding during fiscal 2008 by 259,237 shares because ATK's average stock price exceeded the conversion price during the year. There was no impact on the diluted shares outstanding for fiscal 2009 or 2007 because ATK's average stock price during those years was below the conversion price. Debt issuance costs of approximately $7,200 are being amortized to interest expense over five years. Approximately $100,000 of the net proceeds from the issuance of these notes was used to concurrently repurchase 1,285,200 shares of ATK's common stock.

        In connection with the issuance of the 2.75% Convertible Notes due 2011, ATK purchased, at a cost of $50,850, call options (the Call Options) on its common stock. The Call Options, which become exercisable upon conversion of the related convertible notes, allow ATK to purchase approximately 3.1 million shares of ATK's common stock and/or cash from the counterparty at an amount equal to the amount of common stock and/or cash related to the excess conversion value that ATK would pay to the holders of the related convertible notes upon conversion. For income tax reporting purposes, the related convertible notes and the Call Options are integrated. This creates an original issue discount for income tax reporting purposes, and therefore the cost of the Call Options will be accounted for as interest expense over the term of the convertible notes for income tax reporting purposes. The associated income tax benefits will be recognized in the period in which the deduction is taken for income tax reporting purposes as an increase in additional paid-in capital (APIC) in stockholders' equity. In addition, ATK sold warrants (the Warrants) to issue approximately 3.3 million shares of ATK's common stock at an exercise price of $116.75 per share. The proceeds from the sale of the Warrants totaled $23,220. In accordance with SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities (SFAS No. 133), and Emerging Issues Task Force (EITF) Issue No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock, ATK recorded the net cost of the Call Options and the Warrants of $27,630 in APIC and will not recognize any changes in the fair value of the instruments. On a combined basis, the Call Options and the Warrants are intended to reduce the potential dilution of ATK's common stock in the event that the 2.75% Convertible Notes due 2011 are converted by effectively increasing the conversion price of these notes from $96.51 to $116.75. The Call Options are anti-dilutive and are therefore excluded from the calculation of diluted shares outstanding. The Warrants will result in additional diluted shares outstanding if ATK's average common stock price exceeds $116.75. The Call Options and the Warrants are separate and legally distinct instruments that bind ATK and the counterparty and have no binding effect on the holders of the convertible notes.

        In fiscal 2006, ATK issued $400,000 aggregate principal amount of 6.75% Senior Subordinated Notes (the 6.75% Notes) that mature on April 1, 2016. These notes are general unsecured obligations. Interest on these notes accrues at a rate of 6.75% per annum and is payable semi-annually on April 1 and October 1 of each year. ATK has the right to redeem some or all of these notes from time to time on or after April 1, 2011, at specified redemption prices. Prior to April 1, 2011, ATK may redeem some or all of these notes at a price equal to 100% of their principal amount plus accrued and unpaid

9. Long-Term Debt (Continued)

interest to the date of redemption and a specified make-whole premium. In addition, prior to April 1, 2009, ATK may redeem up to 35% of the aggregate principal amount of these notes, at a price equal to 106.75% of their principal amount plus accrued and unpaid interest to the date of redemption, with the proceeds of certain equity offerings. Debt issuance costs related to these notes of $7,700 are being amortized to interest expense over ten years.

        In fiscal 2005, ATK issued $200,000 aggregate principal amount of 3.00% Convertible Senior Subordinated Notes (the 3.00% Convertible Notes) that mature on August 15, 2024. Interest on these notes is payable on February 15 and August 15 of each year. Starting with the period beginning on August 20, 2014 and ending on February 14, 2015, and for each of the six-month periods thereafter beginning on February 15, 2015, ATK will pay contingent interest during the applicable interest period if the average trading price of these notes on the five trading days ending on the third day immediately preceding the first day of the applicable interest period equals or exceeds 120% of the principal amount of these notes. The contingent interest payable per note within any applicable interest period will equal an annual rate of 0.30% of the average trading price of a note during the measuring period. The contingent interest feature is treated as an embedded derivative under SFAS No. 133, and the fair value of this feature was insignificant at March 31, 2008 and 2007. ATK may redeem some or all of these notes in cash at any time on or after August 20, 2014. Holders of these notes may require ATK to repurchase in cash some or all of these notes on August 15, 2014 and August 15, 2019. Holders may also convert their 3.00% Convertible Notes at a conversion rate of 12.5392 shares of ATK's common stock per $1 principal amount of these notes (a conversion price of $79.75) under the following circumstances: (1) when, during any fiscal quarter, the last reported sale price of ATK stock is greater than or equal to 130% of the conversion price, or $103.68, for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter; (2) if ATK calls these notes for redemption; or (3) upon the occurrence of certain corporate transactions. The stock price condition was satisfied during ATK's second fiscal quarter ended September 30, 2007 and, accordingly, the unamortized debt issuance costs, which were previously being amortized through the first redemption date of these notes, of approximately $3,200 were written off. The stock price condition was met during the quarter ended September 28, 2008 and $547 of these notes were converted during ATK's third fiscal quarter ended December 28, 2008 (settlement occurred in January 2009). The stock price condition was not satisfied during ATK's fourth fiscal quarter of 2009 or 2008; therefore the remaining principal amount of $199,453 as of March 31, 2009, is classified as long-term. In fiscal 2005, ATK amended the indenture to require ATK to satisfy 100% of the principal amount of these notes solely in cash, with any amounts above the principal amount to be satisfied in cash, common stock, or a combination of cash and common stock, at the sole election of ATK. If certain fundamental changes occur on or prior to August 15, 2014, ATK will in certain circumstances increase the conversion rate by a number of additional shares of common stock or, in lieu thereof, ATK may in certain circumstances elect to adjust the conversion rate and related conversion obligation so that these notes are convertible into shares of the acquiring or surviving company. These contingently issuable shares increased the number of ATK's diluted shares outstanding for fiscal 2009, fiscal 2008, and fiscal 2007 by 326,363, 608,324, and 19,040 shares, respectively, because ATK's average stock price exceeded the conversion price during those years.

        In fiscal 2004, ATK issued $280,000 aggregate principal amount of 2.75% Convertible Senior Subordinated Notes (the 2.75% Convertible Notes due 2024) that mature on February 15, 2024. Interest on these notes is payable on February 15 and August 15 of each year. Beginning with the

period beginning on August 20, 2009 and ending on February 14, 2010, and for each of the six-month periods thereafter beginning on February 15, 2010, ATK will pay contingent interest during the applicable interest period if the average trading price of these notes on the five trading days ending on the third day immediately preceding the first day of the applicable interest period equals or exceeds 120% of the principal amount of these notes. The contingent interest payable per note within any applicable interest period will equal an annual rate of 0.30% of the average trading price of a note during the measuring period. The contingent interest feature is treated as an embedded derivative under SFAS No. 133, and the fair value of this feature was insignificant at March 31, 2009 and 2008. ATK may redeem some or all of these notes in cash at any time on or after August 20, 2009. Holders of these notes may require ATK to repurchase in cash some or all of these notes on August 15, 2009, February 15, 2014, or February 15, 2019. Holders may also convert these notes into shares of ATK's common stock at a conversion rate of 12.5843 shares per $1 principal amount of the notes (a conversion price of $79.46) under the following circumstances: (1) when, during any fiscal quarter, the last reported sale price of ATK stock is greater than or equal to 130% of the conversion price, or $103.30, for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter; (2) if ATK calls these notes for redemption; or (3) upon the occurrence of certain corporate transactions. The stock price condition was satisfied during ATK's second fiscal quarter ended September 30, 2007 and, accordingly, the unamortized debt issuance costs, which were previously being amortized through the first redemption date of these notes, of approximately $2,400 were written off. The stock price condition was met during the quarter ended September 28, 2008 and $71 of these notes were converted during ATK's third fiscal quarter ended December 28, 2008 ($10 settled in November 2008 and the remaining $61 settled in January 2009). The stock price condition was not satisfied during ATK's fourth fiscal quarter of 2009 or 2008. Because the remaining notes can be put to ATK at the option of each holder in August 2009, the remaining principal amount of $279,929 is classified as current as of March 31, 2009. In fiscal 2005, ATK amended the indenture to require ATK to satisfy 100% of the principal amount of these notes solely in cash, with any amounts above the principal amount to be satisfied in cash, common stock, or a combination of cash and common stock, at the sole election of ATK. These contingently issuable shares increased the number of ATK's diluted shares outstanding for fiscal 2009, fiscal 2008, and fiscal 2007 by 470,669, 864,282, and 39,283 shares, respectively, because ATK's average stock price exceeded the conversion price during those years.

        The 3.00% Convertible Notes, the 2.75% Convertible Notes due 2024, the 2.75% Convertible Notes due 2011, and the 6.75% Notes rank equal in right of payment with each other and all of ATK's future senior subordinated indebtedness and are subordinated in right of payment to all existing and future senior indebtedness, including the Senior Credit Facility. The outstanding notes are guaranteed on an unsecured basis, jointly and severally and fully and unconditionally, by substantially all of ATK's domestic subsidiaries. Subsidiaries of ATK other than the subsidiary guarantors are minor. All of these guarantor subsidiaries are 100% owned by ATK. These guarantees are senior subordinated obligations of the applicable subsidiary guarantors.

9. Long-Term Debt (Continued)

        The scheduled minimum loan payments on outstanding long-term debt are as follows:

Fiscal 2010	$	293,679
Fiscal 2011		13,750
Fiscal 2012		547,500
Fiscal 2013		—
Fiscal 2014		—
Thereafter		599,453
Total	$	1,454,382

        Although the 2.75% Convertible Notes due 2024 do not contractually mature until 2024, these notes are classified as current on the consolidated balance sheet and within the "Fiscal 2010" category above because the notes can be put to ATK at the option of each holder in August 2009.

        ATK's total debt (current portion of debt and long-term debt) as a percentage of total capitalization (total debt and stockholders' equity) was 70% as of March 31, 2009 and 66% as of March 31, 2008.

        ATK's Senior Credit Facility and the indentures governing the 6.75% Notes, the 2.75% Convertible Notes due 2011, the 2.75% Convertible Notes due 2024, and the 3.00% Convertible Notes impose restrictions on ATK, including limitations on its ability to incur additional debt, enter into capital leases, grant liens, pay dividends and make certain other payments, sell assets, or merge or consolidate with or into another entity. In addition, the Senior Credit Facility limits ATK's ability to enter into sale-and-leaseback transactions. The Senior Credit Facility also requires that ATK meet and maintain specified financial ratios, including a minimum interest coverage ratio and a maximum consolidated leverage ratio. ATK's ability to comply with these covenants and to meet and maintain the financial ratios may be affected by events beyond its control. Borrowings under the Senior Credit Facility are subject to compliance with these covenants. As of March 31, 2009, ATK was in compliance with the financial covenants.

        ATK has limited payment requirements under the Senior Credit Facility over the next few years. ATK's other debt service requirements consist principally of interest expense on its long-term debt. As discussed above, additional cash may be required to repurchase or convert any or all of the convertible notes under certain circumstances. ATK's short-term cash requirements for operations are expected to consist mainly of capital expenditures to maintain and expand production facilities and working capital requirements.

        Cash paid for interest totaled $60,019 in fiscal 2009, $70,807 in fiscal 2008, and $68,939 in fiscal 2007. Cash received for interest totaled $905 in fiscal 2009, $1,431 in fiscal 2008, and $1,212 in fiscal 2007.

Interest Rate Swaps

        ATK may use interest rate swaps to hedge forecasted interest payments and the risk associated with changing interest rates of long-term debt. As of March 31, 2009 and 2008, ATK did not have any outstanding interest rate swaps.

10. Employee Benefit Plans

        ATK provides defined benefit pension plans and defined contribution plans for the majority of its employees. ATK has tax qualified defined benefit plans, supplemental (nonqualified) defined benefit pension plans, and a defined contribution plan. A qualified plan meets the requirements of certain sections of the Internal Revenue Code and, generally, contributions to qualified plans are tax deductible. A qualified plan typically provides benefits to a broad group of employees and may not discriminate in favor of highly compensated employees in coverage, benefits or contributions. In addition, ATK provides medical and life insurance benefits to certain retirees and their eligible dependents through its postretirement plans.

Defined Benefit Plans

        Effective March 31, 2007, ATK adopted the recognition provisions of SFAS No. 158, which requires that the consolidated balance sheet reflect the funded status of the pension and other postretirement (PRB) plans. The funded status of the plans is measured as the difference between the plan assets at fair value and the projected benefit obligation. ATK has recognized the aggregate of all overfunded plans in prepaid pension assets and the aggregate of all underfunded plans within the accrued pension liability and postretirement and postemployment benefits liabilities. The portion of the amount by which the actuarial present value of benefits included in the projected benefit obligation exceeds the fair value of plan assets, payable in the next 12 months, is reflected in other accrued liabilities.

        Previously unrecognized differences between actual amounts and estimates based on actuarial assumptions are included in accumulated other comprehensive loss in our consolidated balance sheet as required by SFAS No. 158. Beginning in fiscal 2008, the difference between actual amounts and estimates based on actuarial assumptions has been recognized in other comprehensive income in the period in which they occur.

        Effective April 1, 2007, ATK adopted the measurement provisions of SFAS No. 158 and remeasured its plan assets and benefit obligations. This changed ATK's measurement date from December 31 to March 31. Other than a change in the discount rate from 5.90% to 6.10%, the assumptions used to remeasure the plan assets and benefit obligation remain unchanged from fiscal 2007. The after-tax cumulative effect changes of this adoption included a decrease of $9,009 in retained earnings; a decrease of $47,576 in accumulated other comprehensive loss, an increase of $30,690 in total assets, and a decrease of $7,877 in total liabilities.

        Pension Plans.    ATK has qualified noncontributory defined benefit pension plans that cover substantially all employees hired prior to January 1, 2007. Eligible non-union employees hired on or after January 1, 2007 and certain union employees are not covered by a defined benefit plan but do receive an employer contribution through a defined contribution plan, discussed below. The defined benefit plans provide either pension benefits based on employee annual pay levels and years of credited service or stated amounts for each year of credited service. ATK funds the plans in accordance with federal requirements calculated using appropriate actuarial methods. Depending on the plan they are covered by, employees generally vest after three or five years.

        ATK also sponsors nonqualified supplemental executive retirement plans which provide certain executives and highly compensated employees the opportunity to receive pension benefits in excess of

89

(Amounts in thousands except share and per share data and unless otherwise indicated)

10. Employee Benefit Plans (Continued)

those payable through tax qualified pension plans. The benefit obligation of these plans is included in the pension information below.

        Other Postretirement Benefit Plans.    Generally, employees who retired from ATK on or before January 1, 2004 and were at least age 55 with at least five or ten years of service, depending on pension plan provisions, are entitled to a pre- and/or post-65 healthcare company subsidy and retiree life insurance benefits. Employees who retired after January 1, 2004, but before January 1, 2006, are only eligible for a pre-65 company subsidy. The portion of the healthcare premium cost borne by ATK for such benefits is based on the pension plan they are eligible for, years of service, and age at retirement.

        The following table shows changes in the benefit obligation, plan assets, and funded status of ATK's qualified and non-qualified pension plans and other PRB plans. Benefit obligation balances presented below reflect the projected benefit obligation (PBO) for our pension plans and accumulated PRB obligations (APBO) or our other PRB plans.

The pension plan with an accumulated benefit obligation in excess of plan assets as of March 31, 2008 is ATK's defined benefit nonqualified supplemental executive retirement plan discussed above.

        During fiscal 2008 ATK recorded a curtailment gain of $778 to recognize the impact on other PRB plans associated with the elimination of future subsidized medical benefits under a negotiated union contract.

        The Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Act) reduced ATK's APBO measured as of December 31, 2005. One of ATK's other PRB plans is actuarially equivalent to Medicare, but ATK does not believe that the subsidies it will receive under the Act will be significant. Because ATK believes that participation levels in its other PRB plans will decline, the impact to ATK's results of operations in any period has not been and is not expected to be significant.

	Union		3.75	%		3.50	%		3.00	%
	Salaried		3.95	%		3.73	%		3.25	%

        In developing the expected long-term rate of return assumption, ATK considers input from its actuaries and other advisors, annualized returns of various major indices over 20-year periods, and ATK's own historical 5-year and 10-year compounded investment returns, which have been in excess of broad equity and bond benchmark indices. The expected long-term rate of return of 9.0% used in fiscal 2009 for the plans was based on an asset allocation range of 30-60% in equity investments, 20-30% in fixed income investments, 5-15% in real estate/real asset investments, 10-25% collectively in hedge fund and private equity investments, and 0-5% in cash investments. The actual return in any fiscal year will likely differ from ATK's assumption, but ATK estimates its return based on long-term projections and historical results. Therefore, any variance in a given year does not necessarily indicate that the assumption should be changed.

        In developing the expected long-term rate of return assumption for other PRB plans, ATK considers input from actuaries, historical returns, and annualized returns of various major indices over

        Since fiscal 2006, health care cost trend rates have been set specifically for each benefit plan and design. Assumed health care cost trend rates have a significant effect on the amounts reported for health care plans. A one-percentage point increase or decrease in the assumed health care cost trend rates would have the following effects:

Plan Assets

        Pension.    ATK's pension plan weighted-average asset allocations at March 31, 2009 and 2008, and the target allocations for fiscal 2010, by asset category are as follows:

		Target Range			Actual as of March 31
Asset Category		2010			2009			2008
Domestic equity			15-30	%		22.3	%		24.0	%

	Total		100	%		100	%		100	%

        Pension plan assets for ATK's qualified pension plans are held in a trust for the benefit of the plan participants and are invested in a diversified portfolio of equity investments, fixed income investments, real asset investments, real estate, timber, energy, hedge funds, private equity, and cash. For certain plan assets where the fair market value is not readily determinable, estimates of the fair value are determined using the best available information including the most recent audited financial statements. ATK's investment objectives for the pension plan assets are to minimize the present value of expected funding contributions and to meet or exceed the rate of return assumed for plan funding purposes over the long term. The nature and duration of benefit obligations, along with assumptions concerning asset class returns and return correlations, are considered when determining an appropriate asset allocation

to achieve the investment objectives. ATK has a Committee which, assisted by outside consultants, evaluates the objectives and investment policies concerning its long-term investment goals and asset allocation strategies. In 2008, ATK modified the pension asset strategy with the objective of reducing volatility relative to pension liabilities while still achieving a competitive investment return, achieving diversification between and within various asset classes, and managing other risks. In order to reduce the volatility between the value of pension assets and liabilities, ATK increased its allocation to fixed income as well as lengthened the duration of its fixed income holdings. ATK regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate. Target allocation ranges are guidelines, not limitations, and occasionally due to market conditions and other factors actual asset allocation may vary above or below a target.

        Plan assets are invested in various asset classes that are expected to produce a sufficient level of diversification and investment return over the long term. The investment goals are (1) to meet or exceed the assumed actuarial rate of return over the long term within reasonable and prudent levels of risk, and (2) to preserve the real purchasing power of assets to meet future obligations. During fiscal 2008, ATK conducted an asset/liability study to provide guidance in setting investment goals with an objective to balance risk. Risk targets are established and monitored against acceptable ranges. All investment policies and procedures are designed to ensure that the plans' investments are in compliance with the Employee Retirement Income Security Act. Guidelines are established defining permitted investments within each asset class.

        There was no direct ownership of ATK common stock included in plan assets as of March 31, 2009 or 2008.

        Other Postretirement Benefits.    ATK's other PRB obligations were 27% and 30% pre-funded as of March 31, 2009 and 2008, respectively.

        Portions of the assets are held in a 401(h) account held within the pension master trust and are invested in the same manner as the pension assets. Approximately 33% and 34% of the assets were held in the 401(h) account as of March 31, 2009 and 2008, respectively. The remaining assets are in fixed income investments. ATK's investment objective for the other PRB plan assets is the preservation and safety of capital.

Contributions

        ATK made a qualified pension plan trust prepayment contribution of $150,000 in April 2009 (fiscal 2010) of which $45,000 was the legally required minimum contribution for fiscal 2010. ATK is not required to make additional contributions to its qualified pension plan in fiscal 2010 but expects to distribute approximately $3,137 directly to retirees under its supplemental executive retirement plans, and contribute approximately $14,700 to its other postretirement benefit plans in fiscal 2010.

Expected Future Benefit Payments

        The following benefit payments, which reflect expected future service, are expected to be paid in the years ending March 31. The pension benefits will be paid primarily out of the pension trust. The postretirement benefit payments are shown net of the expected subsidy for the Medicare prescription drug benefit under the Medicare Prescription Drug, Improvement and Modernization Act of 2003 which are not material to be presented separately.

	Pension Benefits		Other Postretirement Benefits
2010	$	134,949	$	17,658
2011		154,626		16,824
2012		146,242		16,507
2013		150,966		15,829
2014		159,052		15,231
2015 through 2019		933,241		68,447

Termination

        In the event ATK terminates any of the plans under conditions in which the plan's assets exceed that plan's obligations, U.S. government regulations require that a fair allocation of any of the plan's assets based on plan contributions that were reimbursed under U.S. government contracts will be returned to the U.S. government.

Defined Contribution Plan

        ATK also sponsors a defined contribution plan. Participation in this plan is available to substantially all employees, except for those within Eagle. The defined contribution plan is a 401(k) plan to which employees may contribute up to 50% of their pay (subject to limitations). Employee contributions are invested, at the employees' direction, among a variety of investment alternatives including an ATK stock fund. Participants may transfer amounts into and out of the investment alternatives at any time. Effective January 1, 2004, the ATK matching contribution to this plan depends on a participant's years of service and certain other factors. Participants receive:

•

a matching contribution of 100% of the first 3% of the participant's contributed pay plus 50% of the next 2% (or, in certain cases, 3%) of the participant's contributed pay,

•

a matching contribution of 50% up to 6% of the participant's contributed pay,

•

an automatic 6% pre-tax contribution rate (of which participants can either change or opt out) along with a matching contribution of 100% of the first 3% of the participant's contributed pay plus 50% of the next 3% of the participant's contributed pay (subject to one-year vesting) and a non-elective contribution based on recognized compensation and age and service (subject to three-year vesting), or

•

no matching contribution.

10. Employee Benefit Plans (Continued)

        ATK's contributions to the plan were $33,745 in fiscal 2009, $26,411 in fiscal 2008, and $19,998 in fiscal 2007.

        Approximately 1,780, or 9%, of ATK's employees are covered by collective bargaining agreements.

11. Income Taxes

        ATK's income tax provision consists of:

		Years Ended March 31
		2009		2008			2007
Current:
	Federal	$	51,240	$	134,487		$	(1,531	)
	State		1,425		8,913			23
Deferred:
	Federal		103,423		(18,101	)		74,142
	State		10,576		2,359			7,583
Income tax provision		$	166,664	$	127,658		$	80,217

        The items responsible for the differences between the federal statutory rate and ATK's effective rate are as follows:

	Years Ended March 31
	2009			2008			2007
Statutory federal income tax rate		35.0	%		35.0	%		35.0	%
State income taxes, net of federal impact		4.5	%		3.2	%		2.3	%
Goodwill impairment		11.8	%		—	%		—	%
Extraterritorial income benefit		—	%		—	%		(2.0	)%
Domestic manufacturing deduction		(1.2	)%		(1.8	)%		(0.5	)%
Research and development credit		(0.9	)%		(0.5	)%		(1.3	)%
Changes in previous contingencies		—	%		(0.3	)%		(2.6	)%
Other non-deductible costs/(tax benefits), net		0.8	%		0.8	%		(0.5	)%
Change in valuation allowance		1.8	%		—	%		(0.1	)%
Income tax provision		51.8	%		36.4	%		30.3	%

        ATK's provision for income taxes includes both federal and state income taxes. The effective tax rate for fiscal 2009 of 51.8% differs from the federal statutory rate of 35% due to the non-deductibility for tax purposes of the non-cash goodwill impairment charge, valuation allowance related to capital loss carryovers, state income taxes, and other provision adjustments which increased the rate, and the domestic manufacturing deduction (DMD) and research and development (R&D) tax credits which decreased the rate.

        The effective tax rate for fiscal 2008 of 36.4% differs from the federal statutory rate of 35% due to state income taxes and other provision adjustments which increased the rate, and DMD, R&D tax credits, and changes in previous contingencies which decreased the rate.

11. Income Taxes (Continued)

        Deferred income taxes arise because of differences in the timing of the recognition of income and expense items for financial statement reporting and income tax purposes. As of March 31, 2009 and 2008 the components of deferred tax assets and liabilities were as follows:

	Years Ended March 31
	2009			2008
Deferred tax assets	$	798,958		$	616,989
Deferred tax liabilities		(676,727	)		(564,115	)
Valuation allowance		(7,608	)		(2,908	)
Net deferred tax assets	$	114,623		$	49,966

        As of March 31, 2009 and 2008, the deferred tax assets and liabilities resulted from temporary differences related to the following:

		March 31
		2009			2008
	Other comprehensive income provision	$	418,309		$	240,012
	Postretirement benefit obligations		63,645			68,313
	Reserves for employee benefits		53,729			53,578
	Other reserves		26,839			23,521
	State carryforwards		11,641			12,318
	Environmental reserves		8,948			8,405
	Other		9,323			9,788
	Pension		(274,534	)		(227,818	)
	Property, plant, and equipment		(69,010	)		(53,799	)
	Intangible assets		(68,103	)		(63,641	)
	Debt-related		(35,488	)		(26,239	)
	Long-term contract method of revenue recognition		(23,068	)		8,436
	Valuation allowance		(7,608	)		(2,908	)
Net deferred income tax asset		$	114,623		$	49,966

        ATK believes it is more likely than not that the recorded deferred benefits will be realized through the reduction of future taxable income. The valuation allowance of $7,608 at March 31, 2009 relates to capital loss carryovers and certain state net operating loss and credit carryforwards that are not expected to be realized before their expiration. The valuation allowance was increased by $4,700 during fiscal 2009 primarily related to the recognition of a valuation allowance of the outstanding capital loss carryovers of $5,929. The amount was reduced by $1,229 due to the expiration of a capital loss carryforward, expiration of state credit carryforwards, and a change in the amount of state carryforward benefits expected to be utilized before expiration.

        The deferred tax assets include $4,894 related to state tax credit carryforwards and $6,747 for state net operating loss carryforwards. These carryforwards expire as follows: $1,656 through fiscal 2015, $1,307 in fiscal 2016 through fiscal 2020, $2,622 in fiscal 2021 through fiscal 2025, and $4,731 in fiscal 2026 through 2029. The remaining $1,216 as well as alternative minimum tax credits of $109 can be carried forward indefinitely.

11. Income Taxes (Continued)

        The federal R&D tax credit was extended through December 31, 2009. If the federal R&D tax credit is not extended through the end of the fiscal year there would be an unfavorable impact on ATK's fiscal 2010 effective income tax rate.

        Income taxes paid, net of refunds, totaled $118,760 in fiscal 2009, $91,261 in fiscal 2008, and $3,889 in fiscal 2007.

FASB Interpretation No. 48

        As discussed in Note 1, effective April 1, 2007, ATK adopted FIN 48. The cumulative effects of applying this interpretation were recorded as a decrease of $7,676 to retained earnings, an increase of $2,693 to net deferred income tax assets and an increase of $10,369 to accrued income taxes as of April 1, 2007.

        In conjunction with the adoption of FIN 48, ATK classified uncertain tax positions as non-current income tax liabilities unless expected to be paid within one year. ATK also began reporting income tax-related interest income within the income tax provision. In prior periods, such interest income was reported in other income. Penalties and tax-related interest expense are reported as a component of the income tax provision. As of March 31, 2009 and 2008, $2,814 and $1,636 of income tax-related interest and $411and $564 of penalties were included in accrued income taxes, respectively.

        ATK or one of its subsidiaries files income tax returns in the U.S. federal, various U.S. state, and foreign jurisdictions. With few exceptions, ATK is no longer subject to U.S. federal, state and local, or foreign income tax examinations by tax authorities for years prior to 2002. The Internal Revenue Service has completed the audits of ATK through fiscal 2006. ATK is subject to examination in the U.S. federal tax jurisdiction for fiscal 2007 and fiscal 2008. We believe appropriate provisions for all outstanding issues have been made for all open years in all jurisdictions.

        A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

		Year Ended March 31, 2009			Year Ended March 31, 2008
Unrecognized Tax Benefits—beginning of period		$	19,561		$	16,244
	Gross increases—tax positions in prior periods		3,374			1,594
	Gross decreases—tax positions in prior periods		(533	)		(2,228	)
	Gross increases—current-period tax positions		4,841			5,204
	Gross decreases—current-period tax positions		(106	)		(1,253	)
	Lapse of statute of limitations		(1,309	)		—
Unrecognized Tax Benefits—end of period		$	25,828		$	19,561

        As of March 31, 2009 and 2008, the total amount of unrecognized tax benefits was $25,828 and $19,561, respectively, of which $20,407 and $16,819, respectively, would affect the effective tax rate, if recognized. The remaining balance is related to deferred tax items which only impact the timing of tax payments. In the next 12 months it is reasonably possible that the gross liability for unrecognized tax benefits will decrease by $1,125 primarily as a result of the lapsing of statutes of limitations.

12. Commitments

        ATK leases land, buildings, and equipment under various operating leases, which generally have renewal options of one to five years. Rent expense was $68,086 in fiscal 2009, $62,739 in fiscal 2008, and $61,410 in fiscal 2007.

        The following table summarizes ATK's contractual obligations and commercial commitments as of March 31, 2009:

				Payments due by period
		Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Contractual obligations:
Long-term debt		$	1,454,382	$	293,679	$	561,250	$	—	$	599,453
Interest on debt(1)			322,674	$	40,636		102,983		65,967		113,088

(1)

Includes interest on variable rate debt calculated based on interest rates at March 31, 2009. Variable rate debt was approximately 19% of ATK's total debt at March 31, 2009.

        The total liability for uncertain tax positions under FIN 48 at March 31, 2009 was approximately $25,828 (see Note 11). Of this amount, $25,570 is not expected to be paid within 12 months and is therefore classified within other long-term liabilities. ATK is not able to provide a reasonably reliable estimate of the timing of future payments relating to the non-current FIN 48 obligations.

        Pension plan contributions are an estimate of ATK's minimum funding requirements through fiscal 2019 to provide pension benefits for employees based on expected actuarial estimated service accruals through fiscal 2019 pursuant to the Employee Retirement Income Security Act, although ATK may make additional discretionary contributions. These estimates may change significantly depending on the actual rate of return on plan assets, discount rates, discretionary pension contributions, and regulations. A substantial portion of ATK's Plan contributions are recoverable from the U.S. Government as allowable indirect contract costs at amounts generally equal to the pension plan contributions, although not necessarily in the same year the contribution is made.

        ATK currently leases its facility in Magna, Utah from a private party. This facility is used in the production and testing of some of ATK's rocket motors. The current lease extends through September 2022. The lease requires ATK to surrender the property back to its owner in its original condition. While ATK currently anticipates operating this facility indefinitely, ATK could incur significant costs if ATK were to terminate this lease.

12. Commitments (Continued)

        ATK has known conditional asset retirement obligations, such as contractual lease restoration obligations, to be performed in the future, that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the consolidated financial statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability's fair value.

13. Contingencies

        Litigation.    From time to time, ATK is subject to various legal proceedings, including lawsuits, which arise out of, and are incidental to, the conduct of ATK's business. ATK does not consider any of such proceedings that are currently pending, individually or in the aggregate, to be material to its business or likely to result in a material adverse effect on its operating results, financial condition, or cash flows.

        On or about April 10, 2006, a former ATK employee filed a qui tam complaint in federal court in Utah alleging that ATK knowingly submitted claims for payment to the U.S. government for defective LUU series illuminating flares that failed to conform to certain safety specifications and falsely certified compliance with those specifications. The lawsuit was initially filed under seal. ATK was first informed of the lawsuit by the United States Department of Justice (DOJ) on March 13, 2007. Thereafter, the DOJ intervened in the qui tam action and filed an amended complaint on November 2, 2007. On May 29, 2008, ATK filed its answer to the complaint. The DOJ subsequently filed a motion to strike the affirmative defenses set forth in ATK's answer. On July 14, 2008, ATK filed its opposition to the motion to strike. On October 16, 2008, the court granted the motion in part and denied it in part. Discovery is underway in the case.

        ATK denies any allegations of improper conduct. Based on what is known to ATK about the subject matter of the complaint, ATK does not believe that it has violated any law or regulation and believes it has valid defenses to all allegations of improper conduct. Although it is not possible at this time to predict the outcome of the litigation, ATK believes, based on all available information, that the outcome will not have a material adverse effect on its operating results, financial condition or cash flows. Some potential, however, does remain for an adverse judgment that could be material to ATK's financial position, results of operations, or cash flows. As a result of the uncertainty regarding the outcome of this matter, no provision has been made in the financial statements with respect to this contingent liability.

        U.S. Government Investigations.    ATK is also subject to U.S. Government investigations from which civil, criminal, or administrative proceedings could result. Such proceedings could involve claims by the U.S. Government for fines, penalties, compensatory and treble damages, restitution, and/or forfeitures. Under government regulations, a company, or one or more of its operating divisions or subdivisions, can also be suspended or debarred from government contracts, or lose its export privileges, based on the results of investigations. ATK believes, based upon all available information, that the outcome of any such pending government investigations will not have a material adverse effect on its operating results, financial condition, or cash flows.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Amounts in thousands except share and per share data and unless otherwise indicated)

13. Contingencies (Continued)

        Environmental Liabilities.    ATK's operations and ownership or use of real property are subject to a number of federal, state, and local environmental laws and regulations, including those for discharge of hazardous materials, remediation of contaminated sites, and restoration of damage to the environment. At certain sites that ATK owns or operates or formerly owned or operated, there is known or potential contamination that ATK is required to investigate or remediate. ATK could incur substantial costs, including remediation costs, resource restoration costs, fines, and penalties, or third party property damage or personal injury claims, as a result of liabilities associated with past practices or violations of environmental laws or non-compliance with environmental permits.

        The liability for environmental remediation represents management's best estimate of the present value of the probable and reasonably estimable costs related to known remediation obligations. The receivable represents the present value of the amount that ATK expects to recover, as discussed below. Both the liability and receivable have been discounted to reflect the present value of the expected future cash flows, using a discount rate of 1.75% and 2.5% as of March 31, 2009 and 2008, respectively. ATK's discount rate is calculated using the 20-year Treasury constant maturities rate, net of an estimated inflationary factor of 1.9%, rounded to the nearest quarter percent. The following is a summary of the amounts recorded for environmental remediation:

	March 31, 2009						March 31, 2008
	Liability			Receivable			Liability			Receivable
Amounts (payable) receivable	$	(62,080	)	$	37,104		$	(64,204	)	$	39,253
Unamortized discount		5,798			(2,900	)		7,831			(3,811	)
Present value amounts (payable) receivable	$	(56,282	)	$	34,204		$	(56,373	)	$	35,442

        Amounts payable or receivable in periods beyond fiscal 2010 have been classified as non-current on the March 31, 2009 balance sheet. As such, of the $56,282 net liability, $8,363 is recorded within other current liabilities and $47,919 is recorded within other non-current liabilities. Of the $34,204 net receivable, $5,660 is recorded within other current assets and $28,544 is recorded within other non-current assets. As of March 31, 2009, the estimated discounted range of reasonably possible costs of environmental remediation was $56,282 to $83,836.

        ATK expects that a portion of its environmental compliance and remediation costs will be recoverable under U.S. Government contracts. Some of the remediation costs that are not recoverable from the U.S. Government that are associated with facilities purchased in a business acquisition may be covered by various indemnification agreements, as described below.

•

As part of its acquisition of the Hercules Aerospace Company in fiscal 1995, ATK assumed responsibility for environmental compliance at the facilities acquired from Hercules (the Hercules Facilities). ATK believes that a portion of the compliance and remediation costs associated with the Hercules Facilities will be recoverable under U.S. Government contracts, and that those environmental remediation costs not recoverable under these contracts will be covered by Hercules Incorporated, a subsidiary of Ashland Inc., (Hercules) under environmental agreements entered into in connection with the Hercules acquisition. Under these agreements, Hercules has agreed to indemnify ATK for environmental conditions relating to releases or hazardous waste activities occurring prior to ATK's purchase of the Hercules Facilities; fines relating to pre-acquisition environmental compliance; and environmental claims arising out of

102

(Amounts in thousands except share and per share data and unless otherwise indicated)

13. Contingencies (Continued)

breaches of Hercules' representations and warranties. Hercules is not required to indemnify ATK for any individual claims below $50. Hercules is obligated to indemnify ATK for the lowest cost response of remediation required at the facility that is acceptable to the applicable regulatory agencies. ATK is not responsible for conducting any remedial activities with respect to the Kenvil, NJ facility or the Clearwater, FL facility. In accordance with its agreement with Hercules, ATK notified Hercules of all known contamination on non-federal lands on or before March 31, 2000, and on federal lands on or before March 31, 2005.

•

ATK generally assumed responsibility for environmental compliance at the Thiokol Facilities acquired from Alcoa Inc. (Alcoa) in fiscal 2002. While ATK expects that a portion of the compliance and remediation costs associated with the acquired Thiokol Facilities will be recoverable under U.S. Government contracts, ATK has recorded an accrual to cover those environmental remediation costs at these facilities that will not be recovered through U.S. Government contracts. In accordance with its agreement with Alcoa, ATK notified Alcoa of all known environmental remediation issues as of January 30, 2004. Of these known issues, ATK is responsible for any costs not recovered through U.S. Government contracts at Thiokol Facilities up to $29,000, ATK and Alcoa have agreed to split evenly any amounts between $29,000 and $49,000, and ATK is responsible for any payments in excess of $49,000.

•

With respect to the commercial products business' facilities purchased from Blount in fiscal 2002, Blount has agreed to indemnify ATK for certain compliance and remediation liabilities, to the extent those liabilities are related to pre-closing environmental conditions at or related to these facilities. Some other remediation costs are expected to be paid directly by a third party pursuant to an existing indemnification agreement with Blount. Blount's indemnification obligations relating to environmental matters, which extended through December 7, 2006, are capped at $30,000, less any other indemnification payments made for breaches of representations and warranties. The third party's obligations, which extended through November 4, 2007, are capped at approximately $125,000, less payments previously made.

        ATK cannot ensure that the U.S. Government, Hercules, Alcoa, Blount, or other third parties will reimburse it for any particular environmental costs or reimburse ATK in a timely manner or that any claims for indemnification will not be disputed. U.S. Government reimbursements for cleanups are financed out of a particular agency's operating budget and the ability of a particular governmental agency to make timely reimbursements for cleanup costs will be subject to national budgetary constraints. ATK's failure to obtain full or timely reimbursement from the U.S. Government, Hercules, Alcoa, Blount, or other third parties could have a material adverse effect on its operating results, financial condition, or cash flows. While ATK has environmental management programs in place to mitigate these risks, and environmental laws and regulations have not had a material adverse effect on ATK's operating results, financial condition, or cash flows in the past, it is difficult to predict whether they will have a material impact in the future.

13. Contingencies (Continued)

        At March 31, 2009, the aggregate undiscounted amounts payable for environmental remediation costs, net of expected recoveries, are estimated to be:

Fiscal 2010	$	2,703
Fiscal 2011		372
Fiscal 2012		331
Fiscal 2013		2,287
Fiscal 2014		1,743

Total	$	24,976

        There were no material insurance recoveries related to environmental remediation during fiscal 2009, 2008, or 2007.

14. Stockholders' Equity

        ATK has authorized 5,000,000 shares of preferred stock, par value $1.00, none of which has been issued.

        ATK sponsors four stock-based incentive plans, which are the Alliant Techsystems Inc. 1990 Equity Incentive Plan, the Non-Employee Director Restricted Stock Plan, the 2000 Stock Incentive Plan, and the 2005 Stock Incentive Plan. As of March 31, 2009, ATK has authorized up to 1,532,360 common shares under the 2005 Stock Incentive Plan, of which 283,557 common shares are available to be granted. No new grants will be made out of the other three plans.

        There are four types of awards outstanding under ATK's stock incentive plans: performance awards, total stockholder return performance awards (TSR awards), restricted stock, and stock options. ATK issues treasury shares upon the payment of performance awards and TSR awards, grant of restricted stock, or exercise of stock options.

        As of March 31, 2009, there were up to 634,058 shares reserved for performance awards for key employees. Performance shares are valued at the fair value of ATK stock as of the grant date and expense is recognized based on the number of shares expected to vest under the terms of the award under which they are granted. Of these shares, 174,973 shares were earned during fiscal 2009 upon achievement of certain financial performance goals, including sales and EPS, for the fiscal 2007 through fiscal 2009 period and were distributed or deferred in May 2009; up to 198,327 shares will become payable only upon achievement of certain financial performance goals, including sales and EPS, for the fiscal 2008 through fiscal 2010 period; up to 151,680 shares will become payable only upon achievement of certain financial performance goals, including sales and EPS, for the fiscal 2009 through fiscal 2011 period; and up to 44,918 shares will become payable only upon achievement of certain performance goals, including sales, EPS, and return on invested capital, for the fiscal 2010 through fiscal 2012 period. In April 2008, 168,821 shares were distributed or deferred into ATK's non-qualified management deferred compensation plans upon achievement of a specified performance goal relating to supply chain management savings in fiscal 2008.

        As of March 31, 2009, there were up to 64,160 shares reserved for TSR awards for key employees. ATK uses an integrated Monte Carlo simulation model to determine the fair value of the TSR awards.

14. Stockholders' Equity (Continued)

The Monte Carlo model calculates the probability of satisfying the market conditions stipulated in the award. This probability is an input into the trinomial lattice model used to determine the fair value the awards as well as the assumptions of other variables, including the risk-free interest rate and expected volatility of ATK's stock price in future periods. The risk-free rate is based on the U.S. dollar-denominated U.S. Treasury strip rate with a remaining term that approximates the life assumed at the date of grant. The weighted average fair value of TSR awards granted was $30.56 during fiscal 2009. The weighted average assumptions used in estimating the value of the TSR award were as follows:

	Year Ended March 31,
	2009
Risk-free rate		1.17	%
Expected volatility		25.8	%
Expected dividend yield		0	%
Expected award life		3 years

        Restricted stock issued to non-employee directors and certain key employees totaled 67,526 shares in fiscal 2009, 37,713 shares in fiscal 2008, and 38,214 shares in fiscal 2007. Restricted shares vest over periods ranging from one to five years from the date of award and are valued at the fair value of ATK's common stock as of the grant date.

        Stock options may be granted periodically, with an exercise price equal to the fair market value of ATK's common stock on the date of grant, and generally vest from one to three years from the date of grant. Since fiscal 2004, options are generally granted with a seven-year term; most grants prior to that had a ten-year term.

        The weighted average fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model and represents the difference between fair market value on the date of grant and the estimated market value on the expected exercise date. The option pricing model requires ATK to make assumptions. The risk-free rate is based on U.S. Treasury zero-coupon issues with a remaining term that approximates the expected life assumed at the date of grant. Expected volatility is based on the historical volatility of ATK's stock over the past five years. The expected option life is based on the contractual term of the stock option and expected employee exercise and post-vesting employment termination trends. No options were granted during fiscal 2008. The weighted average fair value of options granted was $24.83 and $28.58 during fiscal 2009 and 2007, respectively. The following weighted average assumptions were used for grants:

	Years Ended March 31
	2009			2007
Risk-free rate		2.96	%		4.9	%
Expected volatility		19.11	%		30.9	%
Expected dividend yield		0	%		0	%
Expected option life		5 years			5 years

        Effective April 1, 2006, ATK adopted SFAS 123(R), Share-Based Payments, and related Securities and Exchange Commission (SEC) rules included in Staff Accounting Bulletin (SAB) No. 107. ATK adopted SFAS 123(R) on a modified prospective basis, which requires the application of the accounting

standard to all share-based awards issued on or after the date of adoption and any outstanding share-based awards that were issued but not vested as of the date of adoption. Accordingly, ATK did not restate the financial information for prior fiscal periods as a result of the adoption. SFAS 123(R) requires stock options and other share-based payments made to employees to be accounted for as compensation expense and recorded at fair value. ATK will continue to use the Black-Scholes option pricing model to estimate the fair value of stock options granted.

        Total pre-tax stock-based compensation expense of $18,952, $23,415, and $38,076, was recognized during fiscal 2009, 2008, and 2007, respectively. The total income tax benefit recognized in the income statement for share-based compensation was $7,514, $9,224, and $15,169 during fiscal 2009, 2008, and 2007, respectively.

        A summary of ATK's stock option activity is as follows:

	Year Ended March 31, 2009
	Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)		Aggregate Intrinsic Value (in 000s)
Outstanding at beginning of period		1,168,924		$	58.15
Granted		5,000			105.63
Exercised		(133,262	)		47.87
Forfeited/expired		(2,758	)		61.02
Outstanding at end of period		1,037,904		$	58.70		2.8	$	9.01
Options exercisable at end of period		1,015,153		$	58.12		2.7	$	9.21

        The total intrinsic value of options exercised was $6,379, $16,444, and $15,189 during fiscal 2009, 2008, and 2007, respectively. Total cash received from options exercised was $7,413, $16,310, and $17,452 during fiscal 2009, 2008, and 2007, respectively.

        A summary of ATK's performance share award, TSR award, and restricted stock award activity is as follows:

	Year Ended March 31, 2009
	Shares			Weighted Average Grant Date Fair Value
Nonvested at April 1, 2008		630,324		$	87.85
Granted		182,657			57.21
Canceled/forfeited		(23,210	)		91.32
Vested		(213,345	)		78.66
Nonvested at March 31, 2009		576,426		$	80.67

        As of March 31, 2009, the total unrecognized compensation cost related to nonvested stock-based compensation awards was $31,316 and is expected to be realized over a weighted average period of 1.6 years.

Share Repurchases

        On January 31, 2006, ATK's Board of Directors authorized the repurchase of an additional 5,000,000 shares through January 31, 2008. In February and March 2006, ATK repurchased 1,315,104 shares for $100,000. During fiscal 2007, ATK repurchased 2,585,200 shares for $201,880. During fiscal 2008, ATK repurchased 942,200 shares for $100,068. The Board's authorization expired January 31, 2008. On August 5, 2008, ATK's Board authorized the repurchase of up to an additional 5,000,000 shares. The Board has determined that the repurchase program will serve primarily to offset dilution from the Company's employee and director benefit compensation programs, but it may also be used for other corporate purposes, as determined by the Board. During fiscal 2009, ATK repurchased 299,956 shares for $31,609. As of March 31, 2009, there were 4,700,044 remaining shares authorized to be repurchased.

        Any additional authorized repurchases would be subject to market conditions and ATK's compliance with its debt covenants. ATK's 6.75% Senior Subordinated Notes limit the aggregate sum of dividends, share repurchases, and other designated restricted payments to an amount based on ATK's net income, stock issuance proceeds, and certain other items, less restricted payments made, since April 1, 2001. As of March 31, 2009, this limit was approximately $352,000. As of March 31, 2009, the Senior Credit Facility allows ATK to make unlimited "restricted payments" (as defined in the credit agreement), which among other items, would allow payments for future share repurchases, as long as ATK maintains certain senior debt limits, with an annual limit, when those debt limits are not met, of $50,000 plus proceeds of any equity issuances plus 50% of net income since March 29, 2007.

15. Operating Segment Information

        During fiscal 2009, ATK realigned its business operations. As a result of this realignment, ATK combined the Space division of ATK Mission Systems with ATK Launch Systems into a single group now known as ATK Space Systems. Following this realignment, ATK has three segments: ATK Armament Systems, ATK Mission Systems, and ATK Space Systems. These operating segments are defined based on the reporting and review process used by ATK's chief executive officer. Revenue by product line has not been provided as to do so would be impracticable.

•

ATK Armament Systems, which generated 38% of ATK's external sales in fiscal 2009, produces military ammunition and gun systems; commercial products; and propellant and energetic materials. It also operates the U.S. Army ammunition plants in Independence, Missouri and Radford, Virginia.

•

ATK Mission Systems, which generated 26% of ATK's external sales in fiscal 2009, operates in two business lanes, Weapon Systems and Aerospace Systems, across the following market areas: large-caliber direct fires, force protection, precision guided munitions, missiles, propulsion, missile defense, fuzes and warheads, composites, special mission aircraft, electronic warfare, military aircraft structures, commercial aircraft structures and launce structures.

•

ATK Space Systems, which generated 36% of ATK's external sales in fiscal 2009, produces rocket motor systems for human and cargo launch vehicles, conventional and strategic missiles, missile defense interceptors, small and micro-satellites, satellite components, structures and subsystems, lightweight space deployables and solar arrays, and provides engineering and technical services. Other products include ordnance, such as decoy and illuminating flares.

15. Operating Segment Information (Continued)

        All of ATK's segments derive the majority of their sales from contracts with, and prime contractors to, the U.S. Government. ATK's U.S. Government sales, including sales to U.S. Government prime contractors, during the last three fiscal years were as follows:

Fiscal	U.S. Government Sales		Percent of sales
2009	$	3,486,456		76	%
2008		3,257,000		78	%
2007		2,817,000		79	%

        The military small-caliber ammunition contract, which is reported within ATK Armament Systems, contributed approximately 12%, 12%, and 14% of total fiscal 2009, fiscal 2008, and fiscal 2007 sales, respectively. ATK's contract with NASA for the Reusable Solid Rocket Motors (RSRM) for the Space Shuttle, which is reported within ATK Space Systems, represented 9%, 9%, and 11%, of ATK's total fiscal 2009, fiscal 2008, and fiscal 2007 sales, respectively.

        No single commercial customer accounted for 10% or more of ATK's total sales during fiscal 2009, 2008, or 2007.

        ATK's foreign sales to customers were $385,829 in fiscal 2009, $257,655 in fiscal 2008, and $247,162 in fiscal 2007. Approximately 51% of these sales were in ATK Armament Systems, 37% were in ATK Mission Systems, and 12% were in ATK Space Systems. Sales to no individual country outside the United States accounted for more than 1% of ATK's sales in fiscal 2009. Substantially all of ATK's assets are held in the United States.

        Certain administrative functions are primarily managed by ATK at the corporate headquarters ("Corporate"). Some examples of such functions are human resources, pension and postretirement benefits, corporate accounting, legal, tax, and treasury. Significant assets and liabilities managed at Corporate include those associated with debt, pension and postretirement benefits, environmental liabilities, and income taxes. Pension and postretirement benefit expenses are allocated to each segment based on relative headcount and types of benefits offered in each respective segment. Environmental expenses are allocated to each segment based on the origin of the underlying environmental cost. Transactions between segments are recorded at the segment level, consistent with ATK's financial accounting policies. Intercompany balances and transactions involving different segments are eliminated at ATK's consolidated financial statements level. These eliminations are shown above in "Corporate" and were $26,001, $23,366, and $18,278 for fiscal 2009, 2008, and 2007.

        Quarterly financial data is summarized as follows:

	Diluted earnings (loss) per share		1.64		1.87		1.96		(1.00	)

		Fiscal 2008 Quarter Ended
		July 1		September 30		December 30		March 31
Sales		$	958,372	$	1,029,345	$	1,054,865	$	1,129,143
Gross profit			192,190		198,369		212,664		243,092
Net income			52,404		51,175		58,330		60,438
Earnings per share:
	Basic earnings per share		1.58		1.55		1.79		1.85
	Diluted earnings per share		1.50		1.44		1.65		1.72

        The sum of the per share amounts for the quarters may not equal the total for the year due to the application of the treasury stock method. Dilutive loss per share equals basic loss per share for the fourth quarter of fiscal 2009 due to the fact that dilutive shares outstanding for the quarter are anti-dilutive.

        During the fourth quarter of fiscal 2009, ATK recorded a non-cash goodwill impairment charge of $108,500, as discussed in Note 7. Additionally, ATK recorded additional tax expense for the valuation allowance related to its capital loss carryover of $5,398 as well as a $6,000 write-off of an accounts receivable balance related to a customer bankruptcy filing. During the fourth quarter of fiscal 2008, ATK recorded a pre-tax charge of $6,567 within general and administrative expenses for transaction costs related to an acquisition that was terminated in fiscal 2008.

ITEM 9A.    CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

        ATK's Chief Executive Officer and Chief Financial Officer evaluated the effectiveness of the design and operation of ATK's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934) as of March 31, 2009 and have concluded that ATK's disclosure controls and procedures are effective to ensure that information required to be disclosed by ATK in reports that ATK files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms. These disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports ATK files or submits is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

        During the quarter ended March 31, 2009, there was no change in ATK's internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) that has materially affected, or is reasonably likely to materially affect, ATK's internal control over financial reporting.

111

Management's Report on Internal Control over Financial Reporting

        The management of ATK prepared and is responsible for the consolidated financial statements and all related financial information contained in this Form 10-K. This responsibility includes establishing and maintaining adequate internal control over financial reporting. ATK's internal control over financial reporting was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

        To comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, ATK designed and implemented a structured and comprehensive assessment process to evaluate its internal control over financial reporting. The assessment of the effectiveness of ATK's internal control over financial reporting was based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable assurance and may not prevent or detect misstatements. Management regularly monitors ATK's internal control over financial reporting, and actions are taken to correct any deficiencies as they are identified. Based on our assessment, management has concluded that ATK's internal control over financial reporting is effective as of March 31, 2009.

        Our internal control over financial reporting as of March 31, 2009, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Alliant Techsystems Inc.:
Minneapolis, Minnesota

        We have audited the internal control over financial reporting of Alliant Techsystems Inc. and subsidiaries (the "Company") as of March 31, 2009, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

        Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2009, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

113

        We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended March 31, 2009 of the Company and our report dated May 21, 2009 expressed an unqualified opinion on those financial statements and included an explanatory paragraph regarding the Company's adoption of new accounting standards.

SEPARATION AGREEMENT

AND

GENERAL RELEASE OF CLAIMS

This Separation Agreement and General Release of Claims (“Agreement” or “General Release”) is made and entered into by and between Carl A.  Marchetto for himself and on behalf of his agents, assigns, heirs, executors, administrators, attorneys and representatives (“Mr.  Marchetto”), and Alliant Techsystems Inc., a Delaware corporation, any related corporations or affiliates, subsidiaries, predecessors, successors and assigns, present or former officers, directors, stockholders, board members, agents, employees, and attorneys, whether in their individual or official capacities, delegates, benefit plans and plan administrators, and insurers (“Company” or “ATK”).

WHEREAS, Mr.  Marchetto’s employment shall end as provided in this General Release.  In consideration of Mr.  Marchetto signing and complying with this General Release, ATK agrees to provide him with certain payments and other valuable consideration described below.  Further, ATK and Mr.  Marchetto desire to resolve and settle any and all potential disputes or claims related to his employment or termination of employment.

WHEREAS, ATK has expended significant time and money on promotion, advertising, and the development of goodwill and a sound business reputation through which ATK has developed a list of customers and spent time and resources to learn the customers’ needs for ATK’s services and products.  This information is a valuable, special and unique asset of ATK’s business, which Mr.  Marchetto acknowledges constitutes confidential and proprietary information.

WHEREAS, ATK has expended significant time and money on technology, research, and development through which it has developed products, processes, technologies and services that are valuable, special and unique assets of ATK’s business, which Mr.  Marchetto acknowledges constitute confidential and proprietary information.

WHEREAS, the disclosure to or use by third parties of any of ATK’s confidential or proprietary information, or trade secrets, or Mr.  Marchetto unauthorized use of such information or trade  secrets would seriously harm ATK’s business and cause monetary loss that would be difficult, if not impossible, to measure.

THEREFORE, ATK and Mr.  Marchetto (the “Parties”) mutually agree to the following terms and conditions:

1.Last Day of Employment.  Mr. Marchetto’s employment with ATK is terminated effective January 2, 2009.

(a)Final Paycheck.  ATK will pay Mr. Marchetto for all salary earned through the effective date of the termination of his employment with ATK.  ATK will also pay

for any accrued, but unused vacation/PTO.  Mr. Marchetto’s continuing right, if any, under all other ATK employee benefits plans will be governed by those plans.

(b)Restricted Stock.  Mr. Marchetto has one unvested restricted stock award which was granted on December 31, 2007, for 7300 shares.  Pursuant to the Restricted Stock Award Agreement, 3650 shares (which is 1/2 of the original grant) will vest on December 31, 2008.  Also pursuant to that agreement, the other 3650 shares will vest upon his termination date of January 2, 2009.

(c)Performance Share and Cash Incentive Payment.  Mr. Marchetto has a Performance Share Award Agreement for the Measuring Period of ATK fiscal year 2009 through 2011.  In accordance with that Performance Award Agreement, Mr. Marchetto will receive a prorated number of performance shares and a prorated cash incentive payment; this proration is 9/36.  The number of shares delivered and the amount of any cash payment depend on the plan terms and whether and to what extent ATK meets the objectives that were established when the performance award was granted.

ATK expects to make payment of this award following the completion of the performance period which ATK currently expects to be in May 2011; but in no event will the payment be later than the last day in the calendar year in which the performance period ends.  All payments will be taxed in accordance with the federal and state tax laws that apply and ATK practice and will be subject to the terms of the applicable Performance Award Agreements.

(d)Executive Incentive Plan.  Mr. Marchetto will be eligible to receive an Executive Incentive Plan (EIP) payment for ATK Fiscal Year 2009.  Such payment will be prorated based on his 9/12 months of employment in ATK FY09 and based on the performance and terms as established in the beginning of the fiscal year.  This amount will be paid in a single lump sum payment in cash at the time all other EIP participants receive payment

(e)Deferred Compensation.  Any compensation Mr.  Marchetto deferred under the Alliant Techsystems Inc. Nonqualified Deferred Compensation Plan shall be paid in accordance with his pre-selected distribution options and the terms of that plan.  All existing deferral elections will be governed by the Alliant Techsystems Inc.  Nonqualified Deferred Compensation Plan terms.

2.Severance Benefits.  In exchange for the promises of this Agreement, and after the applicable revocation period has ended, ATK will provide Mr. Marchetto with the severance benefits contained in the Executive Severance Plan and with any additional benefits identified in this Paragraph 2 (together referred to as “Severance Benefits”):

(a)Severance Pay.  ATK will pay Mr. Marchetto a single lump-sum severance payment in the amount of $420,000, which is equal to twelve months base pay.  This severance payment will be subject to all applicable withholdings and will be taxable as payroll wages and provided the seven day revocation period has expired (in accordance with paragraph 9) will be paid no later than January 23, 2009.  No 401(k) deductions will be taken from the

2

payment nor is it pensionable earnings (for example, it is not “Earnings” or “Recognized Compensation”) for purposes of any ATK qualified or non-qualified employee benefits plans.

(b)Additional Lump Sum.  Mr. Marchetto is eligible to receive a single lump-sum payment in the amount of $15,000, to offset the cost of continuing health care coverage.  This amount will be subject to all applicable withholdings and will be taxable as payroll wages.  No 401k deductions will be taken from the payment nor is it pensionable earnings (for example, it is not “Earnings” or “Recognized Compensation”) for purposes of any ATK qualified or non- qualified employee benefits plans.

(c)Outplacement Services.  Mr.  Marchetto will be entitled to participate in executive level outplacement services through Lee Hecht Harrison.

Mr.  Marchetto agrees that this General Release extends to all claims which he may have as of this date against ATK based upon statutory or common law claims for breach of contract, breach of employee handbooks or other policies, breach of promises, fraud, wrongful discharge,

4

defamation, emotional distress, whistleblower claims, negligence, assault, battery, or any other theory, whether legal or equitable.

Mr.  Marchetto agrees that this General Release includes all damages available under any theory  of recovery, including, without limitation, any compensatory damages (including all forms of  back-pay or front-pay), attorneys’ fees, liquidated damages, punitive damages, treble damages,  emotional distress damages, pain and suffering damages, consequential damages, incidental  damages, statutory fines or penalties, and/or costs or disbursements.  Except as stated in Paragraph 7, Mr.  Marchetto is completely and fully waiving any rights under the above stated statutes, regulations, laws, or legal or equitable theories.

6.Breach of Agreement and General Release of Claims.  If Mr.  Marchetto breaches any provision of this Agreement and General Release of Claims, then Mr.  Marchetto will not be entitled to, and shall return, the Severance Benefits provided in Paragraph 2.  Nor will he be entitled to the other benefits provided under this Agreement.  The prevailing party in any action to enforce this Agreement will be entitled to reasonable attorneys’ fees and costs, including in any action under this Paragraph to collect the repayment of applicable consideration.

7.Exclusions from General Release.  Nothing in this Agreement shall release any claims or rights that Mr. Marchetto might have to indemnity and/or contribution from ATK in a third-party claim against him in his capacity as an officer and employee of ATK.  Mr.  Marchetto also is not waiving any right to enforce the terms of this General Release or to challenge the knowing and voluntary nature of this General Release under the ADEA as amended, or his right to assert claims that are based on events that happen after this General Release becomes effective.  Mr.  Marchetto agrees that ATK reserves any and all defenses, which it has or might have against any claims brought by Mr.  Marchetto.  These defenses include, but are not limited to, ATK’s right to seek available costs and attorneys’ fees, and to have any money or other damages that might be awarded to Mr.  Marchetto, reduced by the amount of money paid to him under this Agreement and General Release.  Nothing in this General Release interferes with Mr.  Marchetto’s right to file a charge with the Equal Employment Opportunity Commission (“EEOC”) or to participate in an EEOC investigation or proceeding.  Nevertheless, Mr.  Marchetto understands that he has waived his right to recover any individual relief or money damages, which may be awarded on such a charge.

8.General Release of Claims By ATK.  ATK hereby releases and forever discharges Mr. Marchetto from all claims and causes of action, whether or not ATK currently has knowledge of such claims and causes of action, arising, or which may have arisen, out of or in connection with his employment or termination of employment with ATK.  This is a General Release and extends to all claims which ATK may have as of this date against Mr. Marchetto under any theory, whether legal or equitable.

9.Right to Revoke.  This General Release does not become effective for a period of seven (7) days after Mr.  Marchetto signs it and Mr.  Marchetto has the right to cancel it during that time.  Any decision to revoke this General Release must be made in writing and hand-delivered to ATK or, if sent by mail, postmarked within the seven (7) day time period and

5

10.Unemployment Compensation Benefits.  If Mr.  Marchetto applies for unemployment compensation, ATK will not challenge his entitlement to such benefits.  Mr.  Marchetto understands that ATK does not decide whether any person is eligible for unemployment compensation benefits, or the amount of the benefit.

12.No Adequate Remedy at Law.  Mr.  Marchetto acknowledges and agrees that his breach of the post-employment restrictions provided in Paragraph 3 would cause irreparable harm to the Company and the remedy at law would be inadequate.  Accordingly, if Mr.  Marchetto violates any of the provisions of Paragraph 3, ATK is entitled to injunctive relief in addition to any other legal or equitable remedies.

13.Choice of Law and Venue.  The terms of this General Release will be governed by the laws of Virginia (without regard to conflict of laws principles).  Any legal action to enforce this General Release shall be brought in a competent court of law in Fairfax County, VA.

14.Severability.  If any of the terms of this General Release are deemed to be invalid or unenforceable by a court of law, the validity and enforceability of the remaining provisions of this General Release will not in any way be affected or impaired.  In the event that any court having jurisdiction of the Parties should determine that any of the post-employment restrictions set forth in Paragraph 3 of this General Release are overbroad or otherwise invalid in any respect, Mr.  Marchetto acknowledges and agrees that the court so holding shall construe those provision to cover only that scope, duration or extent of those activities which may validly and enforceably be restricted, and shall enforce the restrictions as so construed.  The Parties acknowledge that uncertainty of the law in this respect and expressly stipulate that this Agreement shall be construed in a manner which renders its provisions valid and enforceable to the maximum extent (not exceeding its express terms) possible under applicable law.

15.No Assignment.  This General Release is personal to Mr.  Marchetto and cannot be assigned to any other person or entity.

16.Attorneys’ Fees.  Mr.  Marchetto understands that he is responsible to pay his own costs and attorneys’ fees, if any, which are incurred in consulting with an attorney about this General Release.

secret information, as well as his obligations to maintain the confidentiality of secret or top secret information.  This General Release supersedes and replaces all prior or contemporaneous discussions, negotiations or understandings regarding Mr.  Marchetto’s termination of employment and the subject matter of this Agreement, whether written or oral, except as set forth herein.  Any modification or addition to this General Release must be in writing, signed by an officer of ATK and Mr.  Marchetto.

18.Offer and Opportunity to Review.

19.Understanding and Acknowledgement.  Mr.  Marchetto understands all of the terms of this General Release and has not relied on any oral statements or explanation by ATK.  Mr.  Marchetto has had adequate time to consult with legal counsel and to consider whether to sign this General Release, and Mr.  Marchetto is signing it knowingly and voluntarily.
