NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Quarter and Nine Months EndedDecember 29, 2013

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

1. Basis of Presentation and Responsibility for Interim Financial Statements

The unaudited condensed consolidated financial statements of Alliant Techsystems Inc. (“the Company” or “ATK”) as set forth in this quarterly report have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission for interim reporting. As permitted under those rules, certain footnotes and other financial information that are normally required by accounting principles generally accepted in the United States can be condensed or omitted. ATK’s accounting policies are described in the notes to the consolidated financial statements in its Annual Report on Form 10-K for the fiscal year ended March 31, 2013 (“fiscal 2013”). Management is responsible for the unaudited condensed consolidated financial statements included in this document. The condensed consolidated financial statements included in this document are unaudited but, in the opinion of management, include all adjustments necessary for a fair presentation of ATK’s financial position as of December 29, 2013, and its results of operations for the quarters and nine months ended December 29, 2013 and December 30, 2012, and cash flows for the nine months ended December 29, 2013 and December 30, 2012.

Sales, expenses, cash flows, assets, and liabilities can and do vary during the year. Therefore, the results and trends in these interim financial statements may not be the same as those for the full year.

This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s consolidated financial statements and notes included in its fiscal 2013 Annual Report on Form 10-K.

2. New Accounting Pronouncements

On February 5, 2013, the FASB issued ASU 2013-02 Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income requiring additional disclosure of items reclassified from other comprehensive income (loss) to net income. This guidance is effective for periods beginning after December 15, 2012 and early application was permitted. ATK has implemented this guidance. Refer to the Note 8 for further detail.

3. Fair Value of Financial Instruments

The current authoritative guidance on fair value 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. Fair value is defined 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 the current authoritative literature 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.

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 which are used to pay benefits under a nonqualified supplemental executive retirement plan for certain executives and highly compensated employees. 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,

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

3. Fair Value of Financial Instruments (Continued)

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. The fair value of these securities is included within other current assets and deferred charges and other non-current assets on the consolidated balance sheet.

Derivative financial instruments and hedging activities—In order to manage its exposure to commodity pricing, interest rate risk, and foreign currency risk, ATK periodically utilizes commodity, interest rate, and foreign currency derivatives, which are considered Level 2 instruments. As discussed further in Note 7, ATK has outstanding commodity forward contracts that were entered into to hedge forecasted purchases of copper and zinc. Commodity derivatives are valued based on prices of futures exchanges and recently reported transactions in the marketplace. During fiscal 2014, ATK entered into five interest rate swaps. These swaps are valued based on future LIBOR rates and the established fixed rate is based primarily on quotes from banks. Foreign currency derivatives are valued based on observable market transactions of spot currency rates and forward currency prices. No foreign currency derivatives were outstanding as of December 29, 2013.

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. We have considered these to be Level 2 instruments.

The following table sets forth by level within the fair value hierarchy ATK's financial assets and liabilities that are measured at fair value on a recurring basis:

4. Acquisitions

In accordance with the accounting standards regarding business combinations, the results of acquired businesses are included in ATK’s consolidated financial statements from the date of acquisition. For each acquisition, the purchase price 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.

Savage Acquisition

On June 21, 2013, ATK acquired Caliber Company, parent company of Savage Sports Corporation ("Savage"), a leading manufacturer of sporting long guns. Operating under the brand names of Savage Arms, Stevens and Savage Range Systems, the company designs, manufactures and markets centerfire and rimfire rifles, shotguns and shooting range systems used for hunting as well as competitive and recreational target shooting. The purchase price was $315,000 net of cash acquired, and is subject to purchase price adjustments expected to be settled in fiscal 2014. ATK believes the acquisition complements ATK's growing portfolio of leading consumer brands and will allow us to build upon our offerings with Savage's prominent, respected brands known for accuracy, quality, innovation, value and craftsmanship. Savage's sales distribution channels, new product development, and sophistication in manufacturing will significantly increase ATK's presence with a highly relevant product offering to distributors, retailers and consumers. Savage employs approximately 600 employees and is included in the Sporting Group. The purchase price allocation will be completed in fiscal 2014. None of the goodwill generated in this acquisition will be deductible for tax purposes.

ATK used the acquisition method of accounting to account for this acquisition and, accordingly, the results of Savage are included in ATK’s consolidated financial statements at the date of acquisition. The purchase price for the acquisition has been preliminarily allocated to the acquired assets and liabilities based on estimated fair value. The preliminary purchase price allocation is subject to further refinement and may require significant adjustments to arrive at the final purchase price allocation. These adjustments will primarily relate to intangible asset valuation, certain contingent liabilities and income tax-related items. We expect the purchase price allocation to be completed within 12 months of the acquisition date. Pro forma information on the results of operations for fiscal 2013 as if the acquisition had occurred at the beginning of fiscal 2013 is not being presented because the acquisition is not material to ATK for that purpose. Subsequent to June 21, 2013, ATK has recorded sales of approximately $116,908 for fiscal year 2014 and $53,920 for the quarter ended December 29, 2013 and income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest of approximately $18,887 for fiscal year 2014 and $13,266 for the quarter ended December 29, 2013 associated with the operations of this acquired business, which reflects the expense of the inventory step-up cost of $9,000 for inventory sold in fiscal year 2014 and none for inventory sold in the quarter ended December 29, 2013.

Bushnell Acquisition

On November 1, 2013, ATK acquired Bushnell Group Holdings, Inc. ("Bushnell"). Bushnell is a leading global designer, marketer and distributor of branded sports optics, outdoor accessories and performance eyewear. The purchase price was $985,000 net of cash acquired, subject to purchase price adjustments. ATK believes the acquisition broadens our existing capabilities in the commercial shooting sports market and expands our portfolio of branded shooting sports products. In addition, this transaction enables the Company to enter new sporting markets in golf and snow skiing. ATK will leverage Bushnell’s strong sourcing, marketing, branding and distribution capabilities and capitalize on Bushnell’s track record of successfully integrating acquisitions and delivering profitable growth. Bushnell employs approximately 1,100 employees and is included in the Sporting Group. The purchase price has been preliminarily allocated based on the estimated fair value of net assets acquired and liabilities assumed at the date of the acquisition. The preliminary purchase price allocation is subject to further refinement and may require significant adjustments to arrive at the final purchase price allocation. These adjustments will primarily relate to intangible asset valuation, certain contingent liabilities and income tax-related items. We expect the purchase price allocation to be completed within 12 months of the acquisition date. A portion of the goodwill generated in this acquisition will be deductible for tax purposes. Subsequent to November 1, 2013, ATK has recorded sales of approximately $85,074 for the quarter and nine months ended December 29, 2013 and income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest of approximately $3,123 for the quarter and nine months ended December 29, 2013 associated with the operations of this acquired business which reflects transition costs and $1,377 of inventory step-up costs. The income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest excludes transaction costs of $10,200 for the quarter ended December 29, 2013.

4. Acquisitions (Continued)

Preliminary Allocation of Consideration Transferred to Net Assets Acquired:

The following amounts represent the preliminary determination of the fair value of identifiable assets acquired and liabilities assumed from the Bushnell acquisition. The final determination of the fair value of certain assets and liabilities will be completed within the 12-month measurement period from the date of acquisition as required. The size and breadth of the Bushnell acquisition will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the asset and liability fair values as of the acquisition date, including the significant contractual and operational factors underlying the trade name and customer relationship intangible assets, the assumptions utilized on certain reserves such as those for inventory obsolescence, the assumptions used in transfer pricing analysis, and the related tax impacts of any changes made. Any potential adjustments made could be material in relation to the preliminary values presented below:

Purchase Price net of cash acquired:
Cash Paid			$	985,000
Cash Paid for additional working capital			4,065
Total purchase price			$	989,065
Fair value of assets acquired:
Net receivables	$	110,923
Net inventories	154,388
Tradename, technology, and customer relationship intangibles	370,727
Property, Plant, and Equipment	25,080
Other assets	10,110
Total assets	671,228
Fair value of liabilities assumed:
Accounts Payable	80,113
Deferred tax liabilities	79,108
Other liabilities	27,263
Total liabilities	$	186,484
Net assets acquired			$	484,744
Preliminary goodwill			$	504,321

Supplemental Pro Forma Data:

ATK used the acquisition method of accounting to account for this acquisition and, accordingly, the results of Bushnell are included in ATK’s consolidated financial statements for the period subsequent to the date of acquisition. The following unaudited supplemental pro forma data for the quarter and nine months ended December 29, 2013 and December 30, 2012 present consolidated information as if the acquisition had been completed on April 1, 2012. The pro forma results were calculated by combining the results of ATK with the stand-alone results of Bushnell for the pre-acquisition periods, which were adjusted to account for certain costs which would have been incurred during this pre-acquisition period:

	QUARTERS ENDED				NINE MONTHS ENDED
(Amounts in thousands except per share data)	December 29, 2013		December 30, 2012		December 29, 2013		December 30, 2012

4. Acquisitions (Continued)

The unaudited supplemental pro forma data above include the following significant non-recurring adjustments made to account for certain costs which would have been incurred if the acquisition had been completed on April 1, 2012, as adjusted for the applicable tax impact:

	QUARTERS ENDED					NINE MONTHS ENDED
(Amounts in thousands)	December 29, 2013			December 30, 2012		December 29, 2013			December 30, 2012

ATK/Bushnell fees for advisory, legal, accounting services2	(8,369		)	—		(11,031		)	11,031

1. Adjustment reflects the increased cost of goods sold expense which results from the fair value step-up in inventory of $3,500 which was expensed over the first inventory cycle.

2. Removed the ATK/Bushnell fees that were incurred in connection with the acquisition of Bushnell from fiscal 2014, and considered those fees as incurred during the first quarter of fiscal 2013. Costs were recorded in General and administrative expense.

There were no acquisitions during fiscal 2013.

5. Goodwill, Intangible Assets, and Deferred Charges and Other Non-Current Assets

The changes in the carrying amount of goodwill by segment were as follows:

	Aerospace Group		Defense Group		Sporting Group		Total
Balance, March 31, 2013	$	676,516	$	366,947	$	208,073	$	1,251,536
Acquisitions	—		—		660,913		660,913

Balance at December 29, 2013	$	676,516	$	366,947	$	870,203	$	1,913,666

The acquisitions in the Sporting Group related to the preliminary purchase price allocation for Savage and Bushnell as previously discussed.

The goodwill recorded within Aerospace Group above is presented net of $108,500 of accumulated impairment losses.

Included in Net intangible assets as of December 29, 2013 and March 31, 2013 are $204,665 and $38,998, respectively, of other intangible assets consisting of trademarks and brand names that are not being amortized as their estimated useful lives are considered indefinite and amortizing assets, as follows:

	December 29, 2013							March 31, 2013
	Gross carrying amount		Accumulated amortization			Total		Gross carrying amount		Accumulated amortization			Total
Trade name	$	188,317	$	(19,707	)	$	168,610	$	66,060	$	(13,531	)	$	52,529

The gross amount of amortizable and non-amortizable intangible assets increased from March 31, 2013 due to the acquisition of Savage and Bushnell. The assets in the table above are being amortized using a straight-line method over a weighted average remaining period of approximately 9.8 years. Amortization expense for the quarter and nine months ended December 29, 2013 was $10,133 and $17,239, respectively. Amortization expense for the quarter and nine months ended December 30, 2012 was $2,665 and $8,400, respectively. ATK expects amortization expense related to these assets to be as follows:

6. 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 and contingently issuable shares related to ATK's Convertible Senior Subordinated Notes (see Note 12) during each period presented, which, if exercised, earned, or converted, would have a dilutive effect on EPS. In computing EPS for the quarter and nine months ended December 29, 2013 and December 30, 2012 earnings, as reported for each respective period, is divided by (in thousands):

	Quarters Ended		Nine months ended
	December 29, 2013	December 30, 2012	December 29, 2013	December 30, 2012
Basic EPS shares outstanding	31,536	32,454	31,701	32,493
Dilutive effect of stock-based awards	256	198	241	148
Dilutive effect of contingently issuable shares	821	—	476	—
Diluted EPS shares outstanding	32,613	32,652	32,418	32,641
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	3	150	3	151

As discussed further in Note 12, contingently issuable shares related to ATK’s 3.00% Convertible Senior Subordinated Notes due 2024 are not included in diluted EPS for the three or nine months ended December 30, 2012 because ATK’s average stock price during these periods did not exceed the triggering price.

7. Derivative Financial Instruments

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 currency 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.

ATK entered into forward contracts for copper and zinc during fiscal 2014 and 2013. The contracts essentially establish a fixed price for the underlying commodity and are designated and qualify as effective cash flow hedges of purchases of the commodity. Ineffectiveness is calculated as the amount by which the change in the fair value of the derivatives exceeds the change in the fair value of the anticipated commodity purchases.

ATK entered into interest rate swaps in the second and third quarters of fiscal 2014 whereby we pay a fixed rate on a total notional amount of $400,000 and receive one-month LIBOR. The fair value of interest rate swap agreements approximates the amount at which they could be settled, based on estimates obtained from the counterparties. We perform assessments of the effectiveness of our hedge instruments on a quarterly basis and during fiscal 2014 determined the hedges to be highly effective. The counterparties to the interest rate swap agreements expose us to credit risk in the event of nonperformance. However, at December 29, 2013, three of the outstanding swap agreements were in a net liability position which would require us to make the net settlement payments to the counterparties, and two of the outstanding swap agreements were in a net asset position which would require the counterparties to make the net settlement payments to ATK. We do not anticipate nonperformance by our counterparties. We do not hold or issue derivative financial instruments for trading purposes.

ATK has not entered into any foreign currency forward contracts during fiscal 2014 or 2013. Contracts entered into prior to fiscal 2013 were used to hedge forecasted inventory purchases and subsequent payments, or customer receivables, denominated in foreign currencies and were designated and qualified as effective cash flow hedges. Ineffectiveness with respect to forecasted inventory purchases was calculated based on changes in the forward rate until the anticipated purchase occurs; ineffectiveness of the hedge of the accounts payable was evaluated based on the change in fair value of its anticipated settlement.

The fair value of the commodity, interest rate, and foreign currency forward contracts are recorded within other assets or liabilities, as appropriate, and the effective portion is reflected in accumulated Other Comprehensive Income (Loss) in the financial statements. The gains or losses on the commodity forward contracts are recorded in inventory as the commodities are purchased. The gains or losses on the foreign currency forward contracts are recorded in earnings when the related inventory is sold. The gains or losses on the interest rate swaps are recorded in interest expense when the interest payments are made.

As of December 29, 2013, ATK had the following outstanding commodity forward contracts that were entered into to hedge forecasted purchases:

	Number of Pounds
Copper	15,252,000
Zinc	5,478,000

As of December 29, 2013, ATK had three outstanding interest rate swaps with notional amounts of $100,000 each with maturity dates in August 2016, 2017, and 2018, as well as two interest rate swaps with notional amounts of $50,000 each with maturity dates in November 2016 and 2017. See footnote 12 for additional information.

As of December 29, 2013, ATK had no outstanding foreign currency forward contracts in place.

Due to the nature of ATK's business, the benefits associated with the commodity contracts may be passed on to the customer and not realized by ATK.

For the periods presented below, the derivative gains and losses in the consolidated income statements related to commodity forward contracts, interest rate swaps, and foreign currency forward contracts were as follows:

	Pretax amount of gain (loss) reclassified from Accumulated Other Comprehensive Income (Loss)				Gain or (loss) recognized in income on derivative (ineffective portion and amount excluded from effectiveness testing)

Interest rate contracts	Interest expense	—			Interest expense	—
Foreign currency forward contracts	Cost of Sales	(30		)	Cost of Sales	—

All derivatives used by ATK during the periods presented were designated as hedging instruments.

During the quarter and nine months ended December 29, 2013 there was a loss of $0 and $1,637, respectively, recognized in earnings as a result of ineffectiveness on forward contracts for copper and zinc. ATK expects that the remaining unrealized losses will be realized and reported in cost of sales as the cost of the commodities is included in cost of sales. Estimated and actual gains or losses will change as market prices change.

12. Long-Term Debt

On November 1, 2013, ATK refinanced its existing credit facility and also entered into $300,000 in Senior Notes, as further discussed below. As of December 29, 2013, long-term debt, including the current portion, consisted of the following:

(1) On November 1, 2013, ATK entered into a Third Amended and Restated Credit Agreement (the "2013 Senior Credit Facility"), which replaced its 2010 Senior Credit Facility. The 2013 Senior Credit Facility is comprised of a Term A Loan of $1,010,000 and a $700,000 Revolving Credit Facility, both of which mature in 2018, and a Term Loan B of $250,000, which matures in 2020. The Term A Loan is subject to quarterly principal payments of $12,625 beginning on March 31, 2014, with the remaining balance due on November 1, 2018. The Term B Loan is subject to quarterly principal payments of $625 beginning on March 31, 2014, with the remaining balance due on November 1, 2020. Substantially all domestic tangible and intangible assets of ATK and its subsidiaries are pledged as collateral under the 2013 Senior Credit Facility. Borrowings under the 2013 Senior Credit Facility bear interest at a rate equal to either the sum of a base rate plus a margin or the sum of a Eurodollar rate plus a margin. Each margin is based on ATK's senior secured credit ratings. Based on ATK's current credit rating, the current base rate margin is 1.00% and the current Eurodollar margin is 2.00%. The weighted average interest rate for the Term A Loan, after taking into account the interest rate swaps discussed below, was 2.60% at December 29, 2013. ATK pays an annual commitment fee on the unused portion of the Revolving Credit Facility based on its senior secured credit ratings. Based on ATK's current rating, this current fee is 0.30%. As of December 29, 2013, ATK had no borrowings against its $700,000 Revolving Credit Facility and had outstanding letters of credit of $124,554, which reduced amounts available on the Revolving Credit Facility to $575,446. Debt issuance costs totaling approximately $19,000 will be amortized over the term of each related Term Loan.

In fiscal 2011, ATK entered into a Second Amended and Restated Credit Agreement (the "2010 Senior Credit Facility"), which was comprised of a Term A Loan of $400,000 and a $600,000 Revolving Credit Facility, both of which were to mature in 2015. During the third quarter of fiscal 2014, the Company refinanced this agreement as noted above. The transaction resulted in the write-off of the remaining $6,166 of unamortized debt issuance costs in the quarter ended December 29, 2013.

(2) On November 1, 2013, ATK issued $300,000 aggregate principal amount of 5.25% Senior Notes (the "5.25% Notes") that mature on October 1, 2021. These notes are general unsecured obligations. Interest on these notes is payable on April 1 and October 1 of each year. ATK has the right to redeem some or all of these notes

12. Long-term Debt (Continued)

from time to time on or after October 1, 2016, at specified redemption prices. Prior to October 1, 2016, 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 October 1, 2016, ATK may redeem up to 35% of the aggregate principal amount of these notes with the net cash proceeds of certain equity offerings, at a price equal to 105.25% of their principal amount plus accrued and unpaid interest to the date of redemption. Debt issuance costs of approximately $3,000 related to these notes will be amortized to interest expense over the term of the notes.

(3) In fiscal 2011, ATK issued $350,000 aggregate principal amount of 6.875% Senior Subordinated Notes ("the 6.875% Notes") that mature on September 15, 2020. These notes are general unsecured obligations. Interest on these notes is payable on March 15 and September 15 of each year. ATK has the right to redeem some or all of these notes from time to time on or after September 15, 2015, at specified redemption prices. Prior to September 15, 2015, 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. Debt issuance costs of approximately $7,100 related to these notes are being amortized to interest expense over 10 years.

(4) 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. Under select conditions, ATK will pay contingent interest on these notes, which is treated as an embedded derivative; the fair value of this feature was insignificant at December 29, 2013 and March 31, 2013. ATK may redeem some or all of these notes in cash, for 100% of the principal amount plus any accrued but unpaid interest, at any time on or after August 20, 2014. Holders of these notes may require ATK to repurchase in cash, for 100% of the principal amount plus any accrued but unpaid interest, some or all of these notes on August 15, 2014 and August 15, 2019. Under specified conditions (including if, during any fiscal quarter, the last reported sale price of ATK’s common stock is greater than or equal to 130% of the conversion price 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), holders may also convert their 3.00% Convertible Notes into shares of ATK’s common stock. These notes had an initial conversion rate of 12.5392 shares per $1 principal amount (a conversion price of $79.75). Pursuant to provisions in the indenture requiring adjustment of the conversion rate upon the payment of dividends, the conversion rate for these notes is now 13.0717, which correspondingly has changed the conversion price per share to $76.50. The stock price condition was met during the quarter ended December 29, 2013; accordingly, the notes are now convertible at any time, at the option of the holder, through March 31, 2014, and will remain convertible so long as ATK’s stock price continues to meet the 130%-of-conversion-price condition, as described above. The stock price condition was also met in fiscal 2009 and $547 of these notes were converted. Because the notes are now convertible and also will be putable within the next year, the remaining principal amount of $199,453 is classified as short-term. The convertible shares had an impact on diluted shares outstanding for the quarter and nine-month periods ended December 29, 2013 of 821,000 and 476,000, respectively, because ATK's average stock price exceeded the conversion price during those periods. These shares had no impact on the diluted shares outstanding for the quarter and nine-month period ended December 30, 2012 as the average stock price did not exceed the conversion price during those periods.

The current authoritative accounting literature requires that issuers of convertible debt instruments that may be settled in cash upon conversion separately account for the liability and equity components in a manner that reflects the entity’s nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. This provision applies to the convertible debt instrument discussed above.

The unamortized discount is amortized through interest expense into earnings over the expected term of the convertible notes. The following table provides additional information about ATK’s 3.00% Convertible Notes:

Based on ATK's closing stock price of $122.05 on December 29, 2013, the if-converted value of these notes exceeded the aggregate principal amount of the notes by $118,755.

Interest Rate Swaps

During fiscal 2014, ATK entered into five floating-to-fixed interest rate swap agreements in order to manage interest costs and the risk associated with variable interest rates. As of December 29, 2013, ATK had the following cash flow hedge interest rate swaps in place:

	Notional		Fair Value			Pay Fixed		Receive Floating		Maturity Date
Non-amortizing swap	$	100,000	$	(661	)	0.87	%	0.16	%	August 2016
Non-amortizing swap	$	100,000	$	(805	)	1.29	%	0.16	%	August 2017
Non-amortizing swap	$	100,000	$	(820	)	1.69	%	0.16	%	August 2018
Non-amortizing swap	$	50,000	$	146		0.65	%	0.16	%	November 2016
Non-amortizing swap	$	50,000	$	193		1.10	%	0.16	%	November 2017

The amount to be paid or received under these swaps is recorded as an adjustment to interest expense.

See Note 9 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013 for additional information regarding the terms and conditions of the Company’s outstanding debt agreements.

Rank and Guarantees

The 5.25% Notes rank senior in right of payment to the 3.00% Convertible Notes and the 6.875% Notes (the latter two of which rank equal with each other), all of which are subordinated in right of payment to all existing and future senior secured 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. The parent company has no independent assets or operations. As a result of the acquisition of Bushnell during the third quarter, ATK's non-guarantor subsidaries become more than minor. See footnote 20 for consolidating financial information of the guarantor and non-guarantor subsidiaries. All of these guarantor subsidiaries are 100% owned by ATK. These guarantees are senior or senior subordinated obligations, as applicable, of the applicable subsidiary guarantors. The guarantee by any Subsidiary Guarantor of ATK’s obligations in respect of the 5.25% Notes and the 6.875% Notes will be released in each of the following circumstances:

• if, as a result of the sale of its capital stock, such Subsidiary Guarantor ceases to be a Restricted Subsidiary;

• if such Subsidiary Guarantor is designated as an “Unrestricted Subsidiary”;

• upon defeasance or satisfaction and discharge of the 5.25% Notes or the 6.875% Notes, as applicable; and

• if such Subsidiary Guarantor has been released from its guarantees of indebtedness under the Credit Agreement and all capital markets debt securities.

The guarantee by any Subsidiary Guarantor of the Company’s obligations in respect of the 3.00% Convertible Notes due 2024 will be released if such Subsidiary Guarantor is released from its guarantee of the 5.25% Notes and the 6.875% Notes.

12. Long-term Debt (Continued)

Scheduled Minimum Loan Payments

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

Remainder of fiscal 2014	$	13,250
Fiscal 2015	252,453
Fiscal 2016	53,000
Fiscal 2017	53,000
Fiscal 2018	53,000
Thereafter	1,684,750
Total	$	2,109,453

ATK's total debt (current portion of debt and long-term debt) as a percentage of total capitalization (total debt and stockholders' equity) was 55% and 42% as of December 29, 2013 and March 31, 2013, respectively.

Covenants and Default Provisions

ATK's Senior Credit Facility and the indentures governing the 5.25% Notes, the 6.875% Notes, 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. ATK’s 5.25% Notes and its 6.875% 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 December 29, 2013, this limit was approximately $839,000. The 2013 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 a certain amount of liquidity and maintains certain senior debt limits, with a limit, when those senior debt limits are not met, of $250,000 plus proceeds of any equity issuances plus 50% of net income since October 7, 2010. The Senior Credit Facility also requires that ATK meet and maintain specified financial ratios, including a minimum interest coverage ratio, a maximum consolidated senior leverage ratio, and a maximum consolidated leverage ratio. Many of ATK's debt agreements contain cross-default provisions so that non-compliance with the covenants within one debt agreement could cause a default under other debt agreements as well. 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 2013 Senior Credit Facility are subject to compliance with these covenants. As of December 29, 2013, ATK was in compliance with the financial covenants.

Cash Paid for Interest on Debt

Cash paid for interest totaled $27,757 in the nine months ended December 29, 2013, and $45,931 in the nine months ended December 30, 2012.

13. Employee Benefit Plans

During the nine months ended December 30, 2012, ATK recorded a settlement expense of $2,000 to recognize the impact of lump sum benefit payments made under the nonqualified supplemental executive retirement plan.

Employer Contributions. During the nine months ended December 29, 2013, ATK contributed $40,000 directly to the pension trust and $2,118 directly to retirees under its nonqualified supplemental executive retirement plan. ATK also contributed $9,559 to its other postretirement benefit plans. ATK anticipates making additional contributions of approximately $1,479 directly to retirees under the nonqualified plan and $2,403 to its other postretirement benefit plans during the remainder of fiscal 2014.

14. Income Taxes

ATK’s provision for income taxes includes federal, foreign, and state income taxes. Income tax provisions for interim periods are based on estimated effective annual income tax rates.

The income tax provisions for the quarters ended December 29, 2013 and December 30, 2012 represent effective tax rates of 32.7% and 31.9%, respectively. The increase in the rate from the prior year quarter is primarily due to current year nondeductible acquisition-related costs and decreased benefits from the domestic manufacturing deduction, partially offset by the favorable true-up of prior-year taxes and the retroactive extension of the research and development credit ("R&D credit") that occurred after the prior year quarter.

The income tax provisions for the nine months endedDecember 29, 2013 and December 30, 2012 represent effective tax rates of 32.7% and 30.0%, respectively. The increase in the rate from the prior year period is primarily due to the prior year period settlement of the examination by the Internal Revenue Service ("IRS") of the fiscal 2009 and 2010 tax returns and nondeductible acquisition-related costs, partially offset by the revaluation of unrecognized tax benefits due to proposed IRS regulations enacted in the second quarter of the current fiscal year.

The IRS released final regulations relating to the capitalization of tangible personal property on September 13, 2013. ATK is currently analyzing the impact of these new regulations. We do not believe they will have a material impact on our financial statements.

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

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 2007. The IRS has completed the audits of ATK through fiscal 2010 and is currently auditing ATK's tax returns for fiscal years 2011 and 2012. We believe appropriate provisions for all outstanding issues have been made for all remaining open years in all jurisdictions.

Although the timing and outcome of audit settlements are uncertain, it is reasonably possible that a $4,686 reduction of the uncertain tax benefits will occur in the next 12 months. The settlement of these unrecognized tax benefits could result in earnings from $0 to $4,294.

15. Stock-Based Compensation

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

Total pre-tax stock-based compensation expense of $3,129 and $4,441 was recognized during the quarters ended December 29, 2013 and December 30, 2012, respectively. Total pre-tax stock-based compensation expense of $9,437 and $10,878 was recognized during the nine months endedDecember 29, 2013 and December 30, 2012, respectively.

The total income tax benefit recognized in the income statement for share-based compensation was $1,199 and $1,246 during the quarters ended December 29, 2013 and December 30, 2012, respectively. The total income tax benefit recognized in the income statement for share-based compensation was $3,620 and $2,496 during the nine months endedDecember 29, 2013 and December 30, 2012, respectively.

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 December 29, 2013, ATK has authorized up to 3,982,360 common shares under the 2005 Stock Incentive Plan, of which 1,325,135 common shares are available to be granted. No new grants will be made out of the other three plans. Furthermore, as of December 29, 2013, no awards remained outstanding under the 2000 Stock Incentive Plan.

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 December 29, 2013, there were up to 418,836 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:

• up to 221,062 shares will become payable only upon achievement of certain financial performance goals, including sales and return on invested capital for the fiscal 2012 through fiscal 2014 period;

• up to 102,848 shares will become payable only upon achievement of certain performance goals, including sales and return on invested capital, for the fiscal 2013 through fiscal 2015 period; and

• up to 94,926 shares will become payable only upon achievement of certain performance goals, including sales and return on invested capital, for the fiscal 2014 through fiscal 2016 period.

There were 35,852 shares earned during fiscal 2013 upon achievement of certain financial performance goals, including EPS, for the fiscal 2011 through fiscal 2013 period, which were distributed or deferred in May 2013. As other financial performance goals were not met, 155,359 shares were forfeited during fiscal 2013.

As of December 29, 2013, there were up to 45,980 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. 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 of 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. There were no TSR awards granted during the nine months endedDecember 29, 2013.

Of the shares reserved for TSR awards for key employees,

15. Stock-based Compensation (Continued)

• 45,980 shares will become payable upon satisfaction of the market conditions stipulated for the fiscal 2012 through 2014 period.

No shares were earned during fiscal 2013 as the market conditions stipulated for the fiscal 2011 through 2013 period were not satisfied and, as such, 26,000 TSR awards were forfeited during fiscal 2013.

Restricted stock granted to non-employee directors and certain key employees totaled 80,834 shares during the nine months endedDecember 29, 2013. Restricted shares vest over periods generally ranging from one to three 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. Options are generally granted with seven-year or ten-year terms. 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 seven 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. The weighted average fair value of options granted was $23.00 during the nine months endedDecember 29, 2013. There were no stock options granted during the nine months endedDecember 30, 2012. The following weighted average assumptions were used for grants:

	Nine Months ended December 29, 2013
Risk-free rate	1.86%
Expected volatility	25.95%
Expected dividend yield	1.58%
Expected option life	7 years

16. 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, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings in any particular quarter, 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 July 30, 2013, Raytheon Company filed a lawsuit against ATK in the Superior Court of the State of Arizona.  The suit involves ATK's longstanding production of rocket motors used in Raytheon's Advanced Medium-Range Air-to-Air Missiles (AMRAAM).  In the filing, Raytheon's primary allegation is that ATK breached certain of the production contracts by not delivering rocket motors.  Raytheon is claiming damages exceeding $100,000.

ATK disputes the allegations of Raytheon's complaint. Although it is not possible at this time to predict the outcome of the litigation, ATK believes, based on all currently available information, that the outcome will not have a material adverse effect on its operating results, financial condition 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.

Claim Recovery.    Profits expected to be realized on contracts are based on management'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. At December 29, 2013, based on progress to date on certain contracts, there is approximately $34,490 included in unbilled receivables for contract claims compared to $27,797 as of March 31, 2013.

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 0.8% as of December 29, 2013 and March 31, 2013, 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:

	December 29, 2013						March 31, 2013
	Liability			Receivable			Liability			Receivable
Amounts (payable) receivable	$	(52,949	)	$	28,685		$	(61,227	)	$	35,638
Unamortized discount	5,863			(2,704		)	3,731			(1,925		)
Present value amounts (payable) receivable	$	(47,086	)	$	25,981		$	(57,496	)	$	33,713

16. Contingencies (Continued)

Amounts expected to be paid or received in periods more than one year from the balance sheet date are classified as non-current. Of the $47,086 discounted liability as of December 29, 2013, $5,049 was recorded within other current liabilities and $42,037 was recorded within other long-term liabilities. Of the $25,981 discounted receivable, ATK recorded $4,650 within other current assets and $21,331 within other non-current assets. As of December 29, 2013, the estimated discounted range of reasonably possible costs of environmental remediation was $47,086 to $75,526.

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 in Note 13 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013.

ATK has been identified as a potentially responsible party (“PRP”), along with other parties, in several regulatory agency actions associated with hazardous waste sites. As a PRP, we may be required to pay a share of the costs of the investigation and clean-up of these sites. While uncertainties exist with respect to the amounts and timing of the ultimate environmental liabilities, based on currently available information, we have concluded that these matters, individually or in the aggregate, will not have a material adverse effect on our operating results, financial condition, or cash flows.

17. Share Repurchases

On January 31, 2012, ATK's Board of Directors authorized a share repurchase program of up to $200,000 worth of shares of ATK common stock, executable over the next two years. On January 29, 2014, ATK's Board of Directors extended the share repurchase program through March 31, 2015. The shares may be purchased from time to time in open market, block purchase, or negotiated transactions, subject to compliance with applicable laws and regulations. The repurchase authorization also allows the Company to make repurchases under Rule 10b5-1 of the Securities Exchange Act of 1934. During the quarter ended December 29, 2013, ATK repurchased 35,253 shares for $3,871 compared to no shares during the quarter ended December 30, 2012. During the nine months endedDecember 29, 2013, ATK repurchased 609,922 shares for $52,130 compared to 482,044 shares for $25,000 during the nine months endedDecember 30, 2012.

18. Changes in Estimates

The majority of ATK’s sales are accounted for as long-term contracts, which are accounted for under the percentage-of-completion method (“POC”). Accounting for contracts under the POC method requires judgment relative to assessing risks and estimating contract revenues and costs. Profits expected to be realized on contracts are based on management’s estimates of total contract sales value and costs at completion. Estimated amounts for contract changes, including scope 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. Changes in estimates of contract sales, costs, or profits are recognized using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on current or prior periods. The effect of the changes on future periods of contract performance is recognized as if the revised estimate had been used since contract inception.

Changes in contract estimates occur for a variety of reasons including changes in contract scope, unforeseen changes in contract cost estimates, positive or negative, due to unanticipated cost growth or risks affecting contract costs and/or the resolution of contract risks at lower costs than anticipated, as well as changes in contract overhead costs over the performance period. Changes in estimates could have a material effect on the Company’s consolidated financial position or annual results of operations. Aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting increased operating income by $19,657 and $28,904 for the quarters ended December 29, 2013 and December 30, 2012, respectively. The current quarter adjustments were primarily driven by higher profit expectations in the Small Caliber Systems and Armament Systems divisions. The prior year quarter adjustments were primarily driven by changes in estimates in Small-Caliber Systems and Space System Operations offset by a reduction in Armament Systems divison.

Aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting increased operating income by $86,937 and $101,532 for the nine months endedDecember 29, 2013 and December 30, 2012, respectively. The current year nine-month period adjustments were primarily driven by higher profit expectations of $39,125 in the Small Caliber Systems division due to operational efficiencies, a successful in-sourcing initiative, and reduced operational risk as a contract nears completion, and for programs in the Space Systems Operations and Aerospace Structures divisions. The

18. Changes in Estimates (Continued)

prior year nine-month period adjustments were primarily driven by changes in estimates in Small Caliber Systems and Energetic Systems as contracts near completion, and changes in estimates in Space System Operations due to performance improvements.

19. Realignment Obligations

In April 2012, ATK commenced operations under a three-group structure. In conjunction with this realignment, ATK incurred realignment charges in the fourth quarter of fiscal 2012. In the quarter and nine months endedDecember 29, 2013, ATK incurred realignment expenses of approximately $2,600 and $8,000, respectively, associated with restructuring and facility rationalization costs in tactical military accessories within the Sporting Group. The charges related primarily to termination benefits offered to employees, asset impairment charges, and costs associated with the closure of certain facilities. ATK had no realignment liability as of March 31, 2013 and December 29, 2013. The following table summarizes ATK’s realignment liability activity during fiscal 2013 related to the termination benefits and facility closure and other costs:

	Termination Benefits			Asset Impairment		Facility Closure and Other Costs		Total

20. Condensed Consolidating Financial Statements

In accordance with the provisions of the 3.00% Convertible Notes, the 6.875% Notes, and the 5.25% Notes, the outstanding notes are guaranteed on an unsecured basis, jointly and severally and fully and unconditionally, by substantially all of ATK's domestic subsidiaries. The parent company has no independent assets or operations. All of these guarantor subsidiaries are 100% owned by ATK. These guarantees are senior or senior subordinated obligations, as applicable, of the applicable subsidiary guarantors. On November 1, 2013, ATK acquired Bushnell, a leading global designer, marketer and distributor of branded sports optics, outdoor accessories and performance eyewear. As a result of this acquisition and the increase in the number of non-guarantor subsidiaries, the subsidiaries of ATK other than the subsidiary guarantors are no longer considered minor and therefore the consolidating financial information of the guarantor and non-guarantor subsidiaries is presented prospectively on the following pages.

21. Operating Segment Information

ATK operates its business structure within three operating groups. These operating segments (“groups”) are defined based on the reporting and review process used by ATK’s chief executive officer and other management.  The operating structure aligns ATK’s capabilities and resources with its customers and markets and positions the Company for long-term growth and improved profitability. Each group is described below: 

• Aerospace Group, which generated 27% of ATK’s external sales in the nine months endedDecember 29, 2013, develops and produces rocket motor systems for human and cargo launch vehicles, conventional and strategic missiles, and missile defense interceptors. They also produce small and micro-satellites, satellite components, structures and subsystems, lightweight space deployables and solar arrays, and provide engineering and technical services.  Additionally, the Aerospace Group operates in the military and commercial aircraft and launch structures markets.  Other products include ordnance, such as decoy and illuminating flares.

• Defense Group, which generated 35% of ATK’s external sales in the nine months endedDecember 29, 2013, develops and produces military small-, medium-, and large-caliber ammunition, propulsion systems for tactical missiles and missile defense applications, strike weapons, precision munitions, gun systems, aircraft survivability systems, fuzes and warheads, energetic materials and special mission aircraft.

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

• Sporting Group, which generated 38% of ATK’s external sales in the nine months endedDecember 29, 2013, develops and produces commercial ammunition, accessories, rifles and shotguns for the hunting, shooting, law enforcement, outdoor and sporting markets.

The military small-caliber ammunition contract, which is reported within the Defense Group, contributed approximately 16% of total external sales during the nine months endedDecember 30, 2012. No contract contributed more than 10% of total external sales during the nine months endedDecember 29, 2013.

The following summarizes ATK's results by segment:

21. Operating Segment Information (Continued)

Costs related to the administrative functions managed by Corporate are either recorded at Corporate or allocated to the business units based on the nature of the expense. The difference between pension and postretirement benefit expense calculated under Financial Accounting Standards and the expense calculated under U.S. Cost Accounting Standards is recorded at the corporate level which provides for greater clarity on the operating results of the business segments. Administrative expenses, such as corporate accounting, legal, and treasury costs, are allocated out to the business segments. 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 $9,689 and $4,935 for the quarters ended December 29, 2013 and December 30, 2012, respectively, and $21,258 and $14,361 for the nine months endedDecember 29, 2013 and December 30, 2012, respectively.

Executive Summary

ATK is an aerospace, defense, and commercial products company and supplier of products to the U.S. Government, allied nations, and prime contractors. ATK is also a major supplier of ammunition, rifles and shotguns, and related accessories to commercial customers and law enforcement agencies. ATK is headquartered in Arlington, Virginia and has operating locations throughout the United States, Puerto Rico, and internationally.

As of December 29, 2013, ATK operated in three business segments. These operating segments are defined based on the reporting and review process used by ATK's chief executive officer and other management. As of December 29, 2013, ATK's three operating groups were:

• Aerospace Group, which generated 27% of ATK's external sales in the nine months endedDecember 29, 2013, develops and produces rocket motor systems for human and cargo launch vehicles, conventional and strategic missiles, and missile defense interceptors. They also produce small and micro-satellites, satellite components, structures and subsystems, lightweight space deployables and solar arrays, and provide engineering and technical services. Additionally, the Aerospace Group operates in the military and commercial aircraft and launch structures markets. Other products include ordnance, such as decoy and illuminating flares.

• Defense Group, which generated 35% of ATK's external sales in the nine months endedDecember 29, 2013, develops and produces military small-, medium-, and large-caliber ammunition, propulsion systems for tactical missiles and missile defense applications, strike weapons, precision munitions, gun systems, aircraft survivability systems, fuzes and warheads, energetic materials and special mission aircraft.

• Sporting Group, which generated 38% of ATK's external sales in the nine months endedDecember 29, 2013, develops and produces commercial ammunition, accessories, rifles and shotguns for the hunting, shooting, law enforcement, outdoor and sporting markets.

Financial Highlights and Notable Events

Certain notable events or activities affecting our fiscal 2014 financial results included the following:

Financial highlights for the quarter ended December 29, 2013

• Quarterly sales of $1.2 billion.

• Diluted earnings per share of $2.46.

• Orders for the quarter ended December 29, 2013 of $1.3 billion compared to $1.4 billion in the quarter ended December 30, 2012. Orders include orders in ATK's Sporting Group, which are cancelable and may not be indicative of future sales.

• Total backlog of $7.6 billion at December 29, 2013 compared to $6.7 billion at December 30, 2012. Backlog includes orders within the Sporting Group which are cancelable, and ATK believes there may have been a number of ammunition orders placed that exceeds actual customer requirements.

35

• Income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest as a percentage of sales was 12.1% and 10.1% for the quarters ended December 29, 2013 and December 30, 2012, respectively. The increase was driven by increases in the Sporting Group, and lower pension expense.

• The increase in the current quarter's tax rate to 32.7% from 31.9% in the quarter ended December 30, 2012 is primarily due to nondeductible acquisition-related costs and lower benefits from the domestic manufacturing deduction, partially offset by a favorable true-up of prior year taxes and extension of the federal R&D tax credit in 2013.

• On November 1, 2013, ATK acquired Bushnell Group Holdings, Inc., a leading global designer, marketer and distributor of branded sports optics, outdoor accessories and performance eyewear, for $985,000 in cash, net of cash acquired, and subject to a customary working capital adjustment.

• On November 1, 2013, ATK entered into a Third Amended and Restated Credit Agreement (the "2013 Senior Credit Facility"), which replaced the 2010 Senior Credit Facility and issued $300,000 aggregate principal amount of 5.25% Senior Notes (‘the "5.25% Notes’’) that mature on October 1, 2021 to pay for the Bushnell acquisition.

• On November 5, 2013, ATK’s Board of Directors declared a quarterly cash dividend of $0.26 per share to stockholders of record on November 20, 2013. The dividend was paid on December 12, 2013.

Other notable events for fiscal 2014

• On January 29, 2014, ATK’s Board of Directors declared a quarterly cash dividend of $0.32 per share, payable on March 27, 2014, to stockholders of record on March 4, 2014.

• On January 29, 2014 ATK's Board of Directors extended the share repurchase program through March 31, 2015.

• On June 21, 2013, ATK acquired Caliber Company, parent company of Savage Sports Corporation ("Savage"), a leading manufacturer of sporting long guns.

• During the nine months endedDecember 29, 2013, ATK repurchased 609,922 shares for $52,130.

• ATK's Board of Directors appointed Jay Tibbets, Senior Vice President and President Sporting Group effective July 31, 2013.

• ATK's Board of Directors appointed Stephen Nolan, Senior Vice President Strategy and Business Development effective July 31, 2013.

Outlook

Government Funding—ATK is dependent on funding levels of the U.S. Department of Defense ("DoD") and NASA.

The government budget structure remains constrained by the 2011 Budget Control Act which initially reduced the DoD topline budget by approximately $490 billion over 10 years starting in fiscal year 2012. In January 2013, the American Taxpayer Relief Act of 2012 was enacted, triggering further defense budget cuts of approximately $50 billion per year (or sequestration) beginning in March 2013. Until recently, Congress and the Administration had been unable to reach a broader fiscal agreement that would amend the Budget Control Act and avoid the impacts of sequestration. For GFY13, the first round of sequestration was triggered, reducing DoD accounts by $37 billion. The NASA budget was under similar sequestration pressure but had greater flexibility to manage the reductions across the portfolio and decided to preserve funding for key priorities such as the Space Launch System ("SLS").

In GFY14, the Administration faced the threat of an additional year of sequestration and deeper cuts requiring an additional reduction of $20 billion from the defense topline budget. The Budget Control Act Amendment adopted in December 2013 provided some relief to the deeper cuts required under sequestration in GFY14 and GFY15. For defense spending, the agreement effectively holds flat the topline budget at $499 billion for both GFY14 and GY15, providing over $30 billion in sequester relief. For NASA, similar relief provided for non-defense discretionary spending should allow the NASA budget to remain flat over the same period at approximately $17.5 billion annually.

On January 17, 2014, Congress approved, and the President signed, the Omnibus Appropriations Act replacing the Continuing Resolution for the remainder of GFY14 and removing the threat of future government shutdowns. Consistent with the budget deal, the Omnibus Appropriations Act funds the DoD at $499 billion and replaces the across-the-board sequester

36

cuts with specific reductions across most accounts. Total funding, and funding for most programs, remains flat at GFY13 levels. Overseas Contingency Operations funding was increased by $5 billion above the requested amount, providing some additional relief to the defense budget.

With the budget agreement now in place, sequestration (the after-the-fact across-the-board cuts) will be replaced in GFY15 with budget submissions expected to be in-line with these lower funding levels and programs adjusted to fit the lower expected funding levels. Budget pressures, such as rising personnel costs despite significant force reductions in the Army and Marine Corps, will present challenges to modernization and research and development accounts. ATK is preparing for a period where force reductions and a winding-down of overseas contingency operations, coupled with reduced training cycles and fairly healthy inventory levels for many ammunition and missile items, will result in less demand in some categories of products.

Given the lack of details provided by the DoD of how it plans to implement the new budget deal, and the expected delay in submission of the GFY15 budget plan, ATK is unable to predict the impact, which could be material, on its programs or financial outlook beyond FY14, including our revenues, operating earnings and margins, cash flow, orders and backlog and recovery of long-lived assets. Further refinement of these assessments will be made after reviewing the Administration’s budget submission, expected in March 2014.

The U.S. defense industry has experienced significant changes over the years. ATK's management believes that the key to ATK's continued success is to focus on performance, innovation, simplicity, and affordability. 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, aircraft and main battle tanks.

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.

The Bipartisan Budget Act of 2013, which was signed by President Obama on December 26, 2013, reduced the allowable compensation costs for employees of government contractors to $487 thousand from the current level of $952 thousand.  This Act will limit the amount of compensation that ATK can propose and bill on contracts awarded after the law is codified into the Federal Acquisition Regulation, expected to be sometime within the next 12 months.  This new limit will be phased in as old contracts that are subject to the old limit are completed and new contracts subject to the new limit are received.  Once fully phased in, ATK believes this Act will reduce the amount of cost ATK can bid and collect.

Critical Accounting Policies

ATK’s significant accounting policies are described in Note 1 to the consolidated financial statements included in ATK’s Annual Report on Form 10-K for the year ended March 31, 2013 (“fiscal 2013”). The accounting policies used in preparing ATK’s interim fiscal 2014 consolidated financial statements are the same as those described in ATK’s Annual Report.

In preparing the consolidated financial statements, ATK follows accounting principles generally accepted in the United States. The preparation of these financial statements requires ATK to make 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 its critical accounting policies are those related to:

• revenue recognition,

• employee benefit plans,

• income taxes,

• acquisitions, and

37

• accounting for goodwill.

More information on these policies can be found in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of ATK’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013.

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.

Group total net Sales, Cost of Sales, and Income before Interest, Loss on Extinguishment of Debt, Income Taxes, and Noncontrolling Interest include intergroup sales and profit. Corporate and Eliminations includes intergroup sales and profit eliminations and corporate expenses.

Acquisitions

On June 21, 2013, ATK acquired Caliber Company, parent company of Savage Sports Corporation ("Savage"), a leading manufacturer of sporting long guns. Operating under the brand names of Savage Arms, Stevens and Savage Range Systems, the company designs, manufactures and markets centerfire and rimfire rifles, shotguns and shooting range systems used for hunting as well as competitive and recreational target shooting. The purchase price was $315,000 net of cash acquired, and is subject to purchase price adjustments expected to be settled in fiscal 2014. ATK believes the acquisition will complement ATK's growing portfolio of leading consumer brands and will allow us to build upon our offerings with Savage's prominent, respected brands known for accuracy, quality, innovation, value and craftsmanship. Savage's sales distribution channels, new product development, and sophistication in manufacturing will significantly increase ATK's presence with a highly relevant product offering to distributors, retailers and consumers. Savage employs approximately 600 employees and is included in the Sporting Group. The purchase price allocation will be completed in fiscal 2014.  None of the goodwill generated in this acquisition will be deductible for tax purposes.

ATK used the acquisition method of accounting to account for this acquisition and, accordingly, the results of Savage 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 2013 as if the acquisition had occurred at the beginning of fiscal 2013 is not being presented because the acquisition is not material to ATK for that purpose. Subsequent to June 21, 2013, ATK has recorded sales of approximately $116,908 for fiscal year 2014 and $53,920 for the quarter ended December 29, 2013 and income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest of approximately $18,887 for fiscal year 2014 and $13,266 for the quarter ended December 29, 2013 associated with the operations of this acquired business which reflects the expense of the inventory step-up cost of $0 and $9,000 for inventory sold in the quarter and nine months ended December 29, 2013, respectively.

On November 1, 2013, ATK acquired Bushnell Group Holdings, Inc. Bushnell is a leading global designer, marketer and distributor of branded sports optics, outdoor accessories and performance eyewear. The purchase price was $985,000 in cash, subject to customary post-closing adjustments expected to be settled in fiscal 2014. ATK believes the acquisition will broaden our existing capabilities in the commercial shooting sports market and expand our portfolio of branded shooting sports products. In addition, this transaction will enable the Company to enter new sporting markets in golf and snow skiing. ATK will leverage Bushnell’s strong sourcing, marketing, branding and distribution capabilities and capitalize on Bushnell’s track record of successfully integrating acquisitions and delivering profitable growth. Bushnell employs approximately 1,100 employees and will be included in the Sporting Group. The purchase price allocation will be completed within 12 months of the acquisition date. A portion of the goodwill generated in this acquisition will be deductible for tax purposes.

ATK will use the acquisition method of accounting to account for this acquisition and, accordingly, the results of Bushnell will be included in ATK’s consolidated financial statements at the date of acquisition. Subsequent to November 1, 2013, ATK has recorded sales of approximately $85,074 for the quarter and nine months ended December 29, 2013, and income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest of approximately $3,123 for the quarter and nine months ended December 29, 2013 associated with the operations of this acquired business which reflects transition costs and the expense of the inventory step-up cost of $1,377 for inventory sold in the quarter and nine months ended December 29, 2013. The income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest excludes transaction costs of $10,200 for the quarter ended December 29, 2013. Pro forma financial statement information has been included within Footnote 4.

38

There were no acquisitions during fiscal 2013.

Sales

The military small-caliber ammunition contract, which is reported within the Defense Group, contributed approximately 16% of total external sales during the nine months endedDecember 30, 2012. No contract contributed more than 10% of total external sales during the nine months endedDecember 29, 2013.

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

Quarter:

Operating expenses increased by $30,427 from the prior-year period. Research and development costs decreased from the prior-year period due to timing of expenditures in the Defense Group. Selling expenses increased primarily due to increased commissions as a result of the acquisition of Bushnell and Savage. General and administrative costs increased due to transaction costs related to acquisitions and the addition of costs associated with Bushnell and Savage.

Nine Months:

Operating expenses increased by $29,333 from the prior-year period. Research and development costs decreased from the prior-year period due to timing of expenditures in Space Systems Operations and the Defense Group. Selling expenses increased primarily due to increased commissions as result of increased sales in the Sporting Group and as a result of the acquisition of Bushnell and Savage. General and administrative costs increased due to transaction costs related to acquisitions and the addition of costs associated with Bushnell and Savage.

The increase in income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest was due to increased sales. Significant changes within the operating segments are also described below.

Quarter:

Aerospace Group.    The decrease was primarily driven by the absence of an award fee in the Group's propulsion business in the prior-year period.

Defense Group.    The decrease is due to reduced sales volume,offset by a variety of operational improvements.

Sporting Group.    The increase primarily reflects higher sales volumes and prices, Bushnell and Savage results, as well as product mix. The increase is partially offset by lower military accessories sales, and inventory step-up and transition costs associated with the Savage and Bushnell acquisitions.

Corporate.    The income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest primarily reflects expenses incurred for administrative functions that are performed centrally at the corporate headquarters, the difference between pension and postretirement benefit expense calculated under the Financial Accounting Standards (FAS) and the expense calculated under U.S. Cost Accounting Standards (CAS), and the elimination of intercompany profits. The change from the prior year is driven by lower pension expenses, partially offset by transaction costs related to acquisitions and increased intercompany transaction eliminations.

Nine Months:

Aerospace Group.    The increase was primarily driven by improved profit expectations in the Aerospace Structures division.

Defense Group.    The decrease is due to the absence of a gain on the sale of residual assets as a result of the loss of the Radford facility management contract, partially offset by higher profit expectations in the Small Caliber Systems division due to operational efficiencies, a successful in-sourcing initiative, and reduced operational risk as a contract nears completion.

Sporting Group.    The increase primarily reflects higher sales volumes and prices, Bushnell and Savage results, as well as product mix. The increase is partially offset by lower military accessories sales, facility rationalization costs, and inventory step-up and transition costs associated with the Savage and Bushnell acquisitions.

Corporate.    The income before interest, income taxes, and noncontrolling interest primarily reflects expenses incurred for administrative functions that are performed centrally at the corporate headquarters, the difference between pension and postretirement benefit expense calculated under the Financial Accounting Standards (FAS) and the expense calculated under U.S. Cost Accounting Standards (CAS), and the elimination of intercompany profits. The change from the prior year is driven by lower pension expenses, partially offset by transaction costs related to acquisitions and increased intercompany transaction eliminations.

The majority of ATK’s sales are accounted for as long-term contracts, which are accounted for under the POC method. Accounting for contracts under the POC method requires judgment relative to assessing risks and estimating contract revenues and costs. Profits expected to be realized on contracts are based on management’s estimates of total contract sales value and costs at completion. Estimated amounts for contract changes, including scope 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. Changes in estimates of contract sales, costs, or profits are recognized using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on

42

current or prior periods. The effect of the changes on future periods of contract performance is recognized as if the revised estimate had been used since contract inception.

Changes in contract estimates occur for a variety of reasons including changes in contract scope, unforeseen changes in contract cost estimates, positive or negative, due to unanticipated cost growth or risks affecting contract costs and/or the resolution of contract risks at lower costs than anticipated, as well as changes in contract overhead costs over the performance period. Changes in estimates could have a material effect on the Company’s consolidated financial position or annual results of operations. During the quarters ended December 29, 2013 and December 30, 2012, the Company recognized favorable operating income adjustments of $42,552 and $55,592, and unfavorable operating income adjustments of $22,895 and $26,688, respectively. The current quarter adjustments were primarily driven by higher profit expectations in the Small Caliber Systems and Armament Systems divisions. The prior-year quarter adjustments were primarily driven by changes in estimates in Small-Caliber Systems and Space System Operations offset by a reduction in the Armament division.During the nine months endedDecember 29, 2013 and December 30, 2012, the Company recognized favorable operating income adjustments of $140,641 and $188,598, and unfavorable operating income adjustments of $53,704 and $87,066, respectively. The current year nine-month period adjustments were primarily driven by higher profit expectations of $39,125 in the Small Caliber Systems division due to operational efficiencies, a successful in-sourcing initiative, and reduced operational risk as a contract nears completion, and for programs in the Space Systems Operations and Aerospace Structures divisions. The prior year period adjustments were primarily driven by changes in estimates in Small Caliber Systems and Energetic Systems as contracts near completion, and changes in estimates in Space System Operations due to performance improvements.

Net Interest Expense

Quarter:

Net interest expense for the quarter ended December 29, 2013 was $26,708, an increase of $12,773 compared to $13,935 in the comparable quarter of fiscal 2013. The increase was due to an increase in the average amount of debt outstanding and the write-off of deferred financing costs due to debt refinancing activity, partially offset by a a decrease in the weighted average interest rate.

Nine Months:

Net interest expense for the nine months endedDecember 29, 2013 was $55,750, an increase of $4,090 compared to $51,660 in the comparable nine-month period of fiscal 2013. The increase was due to an increase in the average amount of debt outstanding and the write-off of deferred financing costs due to debt refinancing activity, partially offset by a decrease in the weighted average interest rate.

Income Tax Provision

	Quarters Ended										Nine Months Ended
	December 29, 2013		Effective Rate		December 30, 2012		Effective Rate		$ Change		December 29, 2013		Effective Rate		December 30, 2012		Effective Rate		$ Change
Income tax provision	$	38,954	32.7	%	$	29,693	31.9	%	$	9,261	$	118,991	32.7	%	$	85,330	30.0	%	$	33,661

ATK’s provision for income taxes includes federal, foreign, and state income taxes. Income tax provisions for interim periods are based on estimated effective annual income tax rates.

The IRS released final regulations relating to the capitalization of tangible personal property on September 13, 2013. ATK is currently analyzing the impact of these new regulations. We do not believe they will have a material impact on our financial statements.

Quarter:

The income tax provisions for the quarters ended December 29, 2013 and December 30, 2012 represent effective tax rates of 32.7% and 31.9%, respectively. The increase in the rate from the prior year quarter is primarily due to current year nondeductible acquisition-related costs and decreased benefits from the domestic manufacturing deduction, partially offset by the favorable true-up of prior-year taxes and the retroactive extension of the research and development credit ("R&D credit") that occurred after the prior-year quarter.

Nine Months:

43

The income tax provisions for the nine months endedDecember 29, 2013 and December 30, 2012 represent effective tax rates of 32.7% and 30.0%, respectively. The increase in the rate from the prior-year period is primarily due to the prior-year period settlement of the examination by the Internal Revenue Service ("IRS") of the fiscal 2009 and 2010 tax returns and nondeductible acquisition-related costs, partially offset by the revaluation of unrecognized tax benefits due to proposed IRS regulations enacted in the second quarter.

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 2007. The IRS had completed the audits of ATK through fiscal 2010 and is currently auditing ATK's tax returns for fiscal years 2011 and 2012. We believe appropriate provisions for all outstanding issues have been made for all remaining open years in all jurisdictions.

Although the timing and outcome of audit settlements are uncertain, it is reasonably possible that a $4,686 reduction of the uncertain tax benefits will occur in the next 12 months. The settlement of these unrecognized tax benefits could result in earnings from $0 to $4,294.

Net Income Before Noncontrolling Interest

Quarter:

Net income before noncontrolling interest for the quarter ended December 29, 2013 was $80,313, an increase of $17,082 compared to $63,231 in the third quarter of fiscal 2013. This change was driven by a $69,543increase in gross profit, partially offset by a $30,427increase in operating expenses, an increase of $12,773 in net interest expense, and an increase of $9,261 in income taxes over the prior-year period.

Nine Months:

Net income before noncontrolling interest for the nine months endedDecember 29, 2013 was $245,120, an increase of $45,779 compared to $199,341 in the comparable period of fiscal 2013. This increase was driven by a $101,090increase in gross profit, a $29,333increase in operating expenses, the absence of a loss on the extinguishment of debt of $11,773, and a decrease of $4,090 in net interest expense, partially offset by an increase of $33,661 income taxes over the prior year.

Noncontrolling Interest

The noncontrolling interest represents the noncontrolling 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.

Liquidity and Capital Resources

ATK manages its business to maximize operating cash flows as the primary source of liquidity. In addition to cash on hand and cash generated by operations, sources of liquidity include a committed credit facility, long-term borrowings, and access to the public debt and equity markets. ATK uses its cash to fund its investments in its existing core businesses and for debt repayment, cash dividends, share repurchases, and acquisition or other activities.

Cash Flow Summary

Cash from operations was $222,284 for the first nine months of fiscal 2014 compared to $118,400 for the first nine months of fiscal 2013. Cash flows provided by operations included the impact of a reduction in pension contributions of $100,000 over the prior year, the absence of a LUU flare settlement payment in the prior year, and decreased tax payments offset by increased working capital, primarily due to the timing of payments and collection of a significant receivable in the prior year. Capital expenditures in the first nine months of fiscal 2014 were $80,580.

44

ATK's cash flows from operating, investing and financing activities, as reflected in the Condensed Consolidated Statement of Cash Flows for the nine months endedDecember 29, 2013 and December 30, 2012 are summarized as follows:

	December 29, 2013			December 30, 2012
Cash flows provided by for operating activities	$	222,284		$	118,400
Cash flows used for investing activities	(1,376,851		)	(61,332		)
Cash flows provided by (used for) financing activities	926,700			(263,960		)
Effect of foreign currency exchange rate fluctuations on cash	335			—
Net cash flows	$	(227,532	)	$	(206,892	)

Operating Activities.

Net cash provided by operating activities increased $103,884 as compared to the prior year. This increase was driven by a $100,000 reduction in funding payment to the pension trust from $140,000 in the prior year to $40,000 during the current year, a reduction in income taxes of $62,500 over the prior year due to timing, and the absence of a $25,500 payment for the LUU flare settlement that was paid in fiscal 2013. These were partially offset by approximately $124,000 more cash required to fund working capital primarily driven by the absence of a significant receivable collection in the prior year and timing of collections and payments.

Cash used for working capital is defined as net receivables plus net inventories, less accounts payables and contract advances.

Investing Activities.

Net cash used for investing activities increased$1,315,519, primarily due to the acquisition of Savage and Bushnell.

Financing Activities.

Net cash provided by financing activities increased $1,190,660 as compared to a use of cash in fiscal 2013. This increase was due to the current year issuance of debt for the acquisition of Bushnell, partially offset by an increase in share repurchases.

Liquidity

In addition to ATK's normal operating cash requirements, the Company's principal future cash requirements will be to fund capital expenditures, debt repayments, employee benefit obligations, share repurchases, dividends, and any strategic acquisitions. 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. ATK's debt service requirements over the next two years consist of principal payments due under the Senior Credit Facility, as discussed further below. ATK's other debt service requirements consist of interest expense on its debt. Additional cash may be required to repurchase or convert any or all of the convertible notes under certain circumstances, including the potential premium above the principal amount of the notes.

During the first nine months ended December 29, 2013, ATK paid dividends totaling $24,951. On January 29, 2014, ATK's Board of Directors declared a quarterly cash dividend of $0.32 per share payable on March 27, 2014, to stockholders of record on March 4, 2014. The payment and amount of any future dividends are at the discretion of the Board of Directors and will be based on a number of factors, including our earnings, liquidity position, financial condition, capital requirements, credit ratings and the availability and cost of obtaining new debt. We cannot be certain that ATK will continue to declare dividends in the future and, as such, the amount and timing of any future dividends are not determinable.

During the third quarter ended December 29, 2013, ATK refinanced the Senior Credit Facility extending the debt maturities and adding additional capacity under our revolving credit facility, which increased our liquidity. 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, through ATK's revolving credit facilities, access to debt and equity markets, as well as potential future sources of funding including additional bank financing and debt markets, will be adequate to fund future growth and service ATK's currently anticipated long-term debt and pension obligations, make capital expenditures, and fund any share repurchases and payment of dividends over the next 12 months.

ATK does not expect that its access to liquidity sources will be materially impacted in the near future. There can be no assurance, however, that the cost or availability of future borrowings, if any, will not be materially impacted by capital market conditions. ATK believes the recent passage of the government FY14 appropriations and the budget agreement for GFY15 to have diminished the possibility of future government shutdowns or disruption in payments.

Long-Term Debt and Credit Facilities

On November 1, 2013, ATK refinanced its existing credit facility and entered into $300,000 in Senior Notes. Due to the refinancing, the Revolving Credit Facility increased by $100,000 from $600,000 to $700,000. See footnote 12 for additional details. As of December 29, 2013, ATK had actual total indebtedness of $2,109,453, and the $700,000 Revolving Credit Facility provided for the potential of additional borrowings up to $575,446. There were no borrowings under the Revolving Credit Facility as of December 29, 2013, and ATK had outstanding letters of credit of $124,554, which reduced the amount available under the facility.

ATK's indebtedness at December 29, 2013 consisted of the following:

	December 29, 2013		March 31, 2013
Senior Credit Facility dated November 1, 2013:

See Note 12 "Long-Term Debt" to the condensed consolidated financial statements in Part I, Item 1 for a detailed discussion of these borrowings.

Senior Credit Facility

On November 1, 2013, ATK entered into a Third Amended and Restated Credit Agreement (the "2013 Senior Credit Facility"), which replaced its 2010 Senior Credit Facility. The 2013 Senior Credit Facility is comprised of a Term A Loan of $1,010,000 and a $700,000 Revolving Credit Facility, both of which mature in 2018, and a Term Loan B of $250,000, which matures in 2020. The Term A Loan is subject to quarterly principal payments of $12,625 beginning on March 31, 2014, with the remaining balance due on November 1, 2018. The Term B Loan is subject to quarterly principal payments of $625 beginning on March 31, 2014, with the remaining balance due on November 1, 2020. As of December 29, 2013, ATK had no outstanding borrowings under the Revolving Credit Facility.

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 either the sum of a base rate plus a margin or the sum of a Eurodollar rate plus a margin. Each margin is based on ATK's senior secured credit ratings. Based on ATK's credit rating as of December 29, 2013, the base rate margin was 1.00% and the Eurodollar margin was 2.00%. ATK must also pay an annual commitment fee on the unused portion of the Revolving Credit Facility.

5.25% Notes due 2021

On November 1, 2013, ATK issued $300,000 aggregate principal amount of 5.25% Senior Notes (the "5.25% Notes") that mature on October 1, 2021. These notes are general unsecured obligations. Interest on these notes is payable 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 October 1, 2016, at specified redemption prices. Prior to October 1, 2016, 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 October 1, 2016, ATK may redeem up to 35% of the aggregate principal amount of these notes with the net

46

cash proceeds of certain equity offerings, at a price equal to 105.25% of their principal amount plus accrued and unpaid interest to the date of redemption.

6.875% Notes due 2020

ATK's 6.875% Notes mature on September 15, 2020. These notes are general unsecured obligations. Interest on these notes accrues at a rate of 6.875% per annum and is payable semi-annually on September 15 and March 15 of each year. ATK has the right to redeem some or all of these notes on or after September 15, 2015, at specified redemption prices. Prior to September 15, 2015, 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.

3.00% Convertible Notes due 2024

ATK's 3.00% Convertible Notes mature on August 15, 2024. Interest on these notes is payable on February 15 and August 15 of each year. Beginning August 20, 2014, ATK will be required to pay contingent interest at a rate driven by the average trading price of these notes if the trading price reaches specified levels during the measurement period.

ATK may redeem 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 the Notes on August 15, 2014 and August 15, 2019. Upon such note redemption or repurchase, ATK will also be required to satisfy certain deferred tax liabilities related to the notes. Based on the stock price as of the end of the third quarter, ATK does not expect there to be a tax liability if the redemption occurs on August 15, 2014. Holders may also convert their notes at a conversion rate of 13.0717 shares of ATK's common stock per $1 principal amount of these notes (a conversion price of $76.50 per share) in the event that the ATK stock price exceeds certain levels, if ATK were to call these notes for redemption, or upon the occurrence of certain corporate transactions. As of December 29, 2013 the conditions necessary for the holders to request their notes be converted has been met and holders will be allowed to convert at any time during ATK's fourth quarter. 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.

Rank and Guarantees

The 5.25% Notes rank senior in right of payment to the 3.00% Convertible Notes and the 6.875% Notes (the latter two of which rank equal with each other), all of which are subordinated in right of payment to all existing and future senior secured 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. The parent company has no independent assets or operations. See footnote 20 for consolidating financial information of the guarantor and non-guarantor subsidiaries, as subsidiaries of ATK other than the subsidiary guarantors are more than minor. All of these guarantor subsidiaries are 100% owned by ATK. These guarantees are senior or senior subordinated obligations, as applicable, of the applicable subsidiary guarantors.

Covenants

ATK's Senior Credit Facility imposes 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 the following financial ratios:

	Senior Leverage Ratio*	Leverage Ratio*	Interest Coverage Ratio†
Requirement	3.00	4.00	3.00
Actual at December 29, 2013	1.56	2.67	8.10
* Not to exceed the required financial ratio
† Not to be below the required financial ratio

The Leverage Ratio is the sum of ATK's total debt plus financial letters of credit and surety bonds, net of up to $100,000 of cash, divided by Covenant EBITDA (which includes adjustments for items such as non-recurring or extraordinary non-cash items, non-cash charges related to stock-based compensation, and intangible asset impairment charges, as well as inclusion of EBITDA of acquired companies on a pro forma basis) for the past four fiscal quarters. The Senior Leverage Ratio is the sum of ATK's senior debt plus financial letters of credit and surety bonds, net of up to $100,000 of cash, divided by Covenant EBITDA. The Interest Coverage Ratio is Covenant EBITDA divided by interest expense (excluding non-cash charges).

47

Many of ATK's debt agreements contain cross-default provisions so that non-compliance with the covenants within one debt agreement could cause a default under other debt agreements as well. 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. The indentures governing the 5.25% Senior Notes, the 6.875% Notes, and the 3.00% Convertible Notes also 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. As of December 29, 2013, ATK was in compliance with the covenants in all of its debt agreements and expects to be in compliance for the foreseeable future.

Share Repurchases

On January 31, 2012, ATK's Board of Directors authorized a share repurchase program of up to $200,000 worth of shares of ATK common stock, executable over the next two years. On January 29, 2014, ATK's Board of Directors extended the share repurchase program through March 31, 2015. The shares may be purchased in open market, block purchase, or negotiated transactions, subject to compliance with applicable laws and regulations. The repurchase authorization also allows the Company to make repurchases under Rule 10b5-1 of the Securities Exchange Act of 1934. During the nine months endedDecember 29, 2013, ATK repurchased 609,922 shares for $52,130 compared to 482,044 shares for $25,000 in the nine months endedDecember 30, 2012.

Any additional authorized repurchases would be subject to market conditions and ATK's compliance with its debt covenants. ATK's 6.875% 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 December 29, 2013, this limit was approximately $839,000. As of December 29, 2013, 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 a certain amount of liquidity and maintains certain senior debt limits. When those requirements are not met, the limit is equal to $250,000 plus proceeds of any equity issuances plus 50% of net income since October 7, 2010. The Senior Credit Facility also prohibits dividend payments if loan defaults exist or the financial covenants contained in the Facility are not met.

Shelf Registration

On September 10, 2013, ATK filed a shelf registration statement with the Securities and Exchange Commission allowing ATK to issue an unspecified aggregate amount of debt and/or equity securities from time to time.

Other Contractual Obligations and Commitments

There have been no material changes with respect to the contractual obligations and commitments or off-balance sheet arrangements described in ATK’s Annual Report on Form 10-K for fiscal 2013, except on November 1, 2013, ATK refinanced its existing credit facility and issued $300,000 in Senior Notes. See footnote 12 for additional detail.

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, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings in any particular quarter, 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.

In April 2012, ATK made a payment to settle the claim associated with the LUU flare litigation which was accrued for during fiscal 2012.

On July 30, 2013, Raytheon Company filed a lawsuit against ATK in the Superior Court of the State of Arizona.  The suit involves ATK's longstanding production of rocket motors used in Raytheon's Advanced Medium-Range Air-to-Air Missiles (AMRAAM).  In the filing, Raytheon's primary allegation is that ATK breached certain of the production contracts by not delivering rocket motors.  Raytheon is claiming damages exceeding $100,000.

ATK disputes the allegations of Raytheon's complaint. Although it is not possible at this time to predict the outcome of the litigation, ATK believes, based on all currently available information, that the outcome will not have a material adverse effect on its operating results, financial condition 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,

48

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 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 0.80% as of December 29, 2013 and March 31, 2013, 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:

	December 29, 2013						December 30, 2012
	Liability			Receivable			Liability			Receivable
Amounts (payable) receivable	$	(52,949	)	$	28,685		$	(61,227	)	$	35,638
Unamortized discount	5,863			(2,704		)	3,731			(1,925		)
Present value amounts (payable) receivable	$	(47,086	)	$	25,981		$	(57,496	)	$	33,713

As of December 29, 2013, the estimated discounted range of reasonably possible costs of environmental remediation was $47,086 to $75,526.

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 in Note 13 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2013.

ATK has been identified as a potentially responsible party (“PRP”), along with other parties, in several regulatory agency actions associated with hazardous waste sites. As a PRP, we may be required to pay a share of the costs of the investigation and clean-up of these sites. While uncertainties exist with respect to the amounts and timing of the ultimate environmental liabilities, based on currently available information, we have concluded that these matters, individually or in the aggregate, will not have a material adverse effect on our operating results, financial condition, or cash flows.

Other Contingencies. ATK is also subject to a number of other potential risks and contingencies. These risks and contingencies are described in Item 1A of Part I of ATK’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013.

New Accounting Pronouncements

See Note 2 to the unaudited condensed consolidated financial statements in Item 1 of Part I of this report.

Inflation and Commodity Price Risk

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. In particular, the prices of commodity metals, such as lead, steel, zinc, and copper, continue to be volatile. These prices generally impact our small-caliber ammunition and commercial ammunition businesses.

49

With respect to ATK's commercial ammunition business, ATK has a strategic sourcing and price strategy to mitigate risk from commodity price fluctuation. 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 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.

Significant increases in commodities can negatively impact operating results with respect to ATK's firm fixed-price contract to supply the DoD's small-caliber ammunition needs and ATK's sales within commercial ammunition. Depending on market conditions, ATK has entered into futures contracts in order to reduce the impact of metal price fluctuations. The majority of the impact has been mitigated on the four-year small-caliber ammunition supply contract, as well as the new seven-year contract with the U.S. Army by the terms within that contract, which is expected to continue into 2019. ATK has entered into futures contracts and purchase orders for the current expected production requirements for fiscal 2014 for both the small-caliber ammunition supply contract and the production of commercial ammunition, thereby mitigating near-term market risk; however, if metal prices exceed pre-determined levels, the Defense and Sporting Groups' operating results could be adversely impacted.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See discussion within Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in the section titled “Inflation and Commodity Price Risk.”

During the quarter ended December 29, 2013, ATK completed the acquisition of Bushnell. As a result of this acquisition, ATK conducts business in various locations throughout the world and is subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. ATK may use derivative financial instruments to manage these risks. The functional currencies of our foreign operating locations are the local currency in the country of domicile. We manage these operating activities at the local level, and revenues, costs, assets and liabilities are generally denominated in local currencies, thereby mitigating the risk associated with changes in foreign exchange rates. However, our results of operations and assets and liabilities are reported in U.S. dollars and thus will fluctuate with changes in exchange rates between those local currencies and the U.S. dollar. From time to time, we may enter in to short-duration foreign currency contracts to hedge foreign currency risks.

There have been no other material changes in ATK’s market risk during the quarter ended December 29, 2013. For additional information, refer to Item 7A of Part II of ATK’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013.

ITEM 4.    CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

As of December 29, 2013, 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) 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 Securities and Exchange Commission’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 December 29, 2013, ATK completed the acquisition of Bushnell, which is being integrated into ATK’s Sporting Group. As part of our ongoing integration activities, we are continuing to incorporate our controls and procedures into the Bushnell business and to augment our company-wide controls to reflect the risks inherent in an acquisition of this magnitude and complexity. There were no changes in ATK’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) that have materially affected, or are reasonably likely to materially affect, ATK’s internal control over financial reporting.

ATK’s report on our internal control over financial reporting in the Annual Report on Form 10-K for the year ending March 31, 2014 will include a scope exception that excludes the acquired Bushnell business in order for management to have sufficient time to evaluate and implement our internal control over financial reporting.

PART II—OTHER INFORMATION

ITEM 1.    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, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings in any particular quarter, 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.

ATK disputes the allegations of Raytheon's complaint.

The description of certain environmental matters contained in Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under the heading “Contingencies,” is incorporated herein by reference.

ITEM 1A.    RISK FACTORS

While ATK attempts to identify, manage and mitigate risks and uncertainties associated with its business to the extent practical under the circumstances, some level of risk and uncertainty will always be present. Item 1A of Part I of ATK’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013 describes all known material risks and uncertainties associated with its business. These risks and uncertainties have the potential to materially affect ATK’s business, financial condition, results of operations, cash flows, projected results, and future prospects.

The shares may be purchased from time to time in open market, block purchase, or negotiated transactions, subject to compliance with applicable laws and regulations. The repurchase authorization also allows the Company to make repurchases under Rule 10b5-1 of the Securities Exchange Act of 1934. In the nine months endedDecember 29, 2013, ATK repurchased 609,922 shares under this program for $52.1 million.

The unaudited condensed consolidated financial statements of Alliant Techsystems Inc. (“the Company” or “ATK”) as set forth in this quarterly report have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission for interim reporting. As permitted under those rules, certain footnotes and other financial information that are normally required by accounting principles generally accepted in the United States can be condensed or omitted. ATK’s accounting policies are described in the notes to the consolidated financial statements in its Annual Report on Form 10-K for the fiscal year ended March 31, 2013 (“fiscal 2013”). Management is responsible for the unaudited condensed consolidated financial statements included in this document. The condensed consolidated financial statements included in this document are unaudited but, in the opinion of management, include all adjustments necessary for a fair presentation of ATK’s financial position as of December 29, 2013, and its results of operations for the quarters and nine months ended December 29, 2013 and December 30, 2012, and cash flows for the nine months ended December 29, 2013 and December 30, 2012.

Sales, expenses, cash flows, assets, and liabilities can and do vary during the year. Therefore, the results and trends in these interim financial statements may not be the same as those for the full year.

This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s consolidated financial statements and notes included in its fiscal 2013 Annual Report on Form 10-K.

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, strategic growth costs, and income taxes.

Costs related to the administrative functions managed by Corporate are either recorded at Corporate or allocated to the business units based on the nature of the expense. The difference between pension and postretirement benefit expense calculated under Financial Accounting Standards and the expense calculated under U.S. Cost Accounting Standards is recorded at the corporate level which provides for greater clarity on the operating results of the business segments. Administrative expenses, such as corporate accounting, legal, and treasury costs, are allocated out to the business segments. 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 $9,689 and $4,935 for the quarters ended December 29, 2013 and December 30, 2012, respectively, and $21,258 and $14,361 for the nine months endedDecember 29, 2013 and December 30, 2012, respectively.

Nonrecurring Adjustments [Abstract]

Schedule of Purchase Price Allocation [Table Text Block]

The following amounts represent the preliminary determination of the fair value of identifiable assets acquired and liabilities assumed from the Bushnell acquisition. The final determination of the fair value of certain assets and liabilities will be completed within the 12-month measurement period from the date of acquisition as required. The size and breadth of the Bushnell acquisition will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the asset and liability fair values as of the acquisition date, including the significant contractual and operational factors underlying the trade name and customer relationship intangible assets, the assumptions utilized on certain reserves such as those for inventory obsolescence, the assumptions used in transfer pricing analysis, and the related tax impacts of any changes made. Any potential adjustments made could be material in relation to the preliminary values presented below:

Purchase Price net of cash acquired:
Cash Paid			$	985,000
Cash Paid for additional working capital			4,065
Total purchase price			$	989,065

Total liabilities	$	186,484
Net assets acquired			$	484,744

Business Acquisition, Pro Forma Information [Table Text Block]

ATK used the acquisition method of accounting to account for this acquisition and, accordingly, the results of Bushnell are included in ATK’s consolidated financial statements for the period subsequent to the date of acquisition. The following unaudited supplemental pro forma data for the quarter and nine months ended December 29, 2013 and December 30, 2012 present consolidated information as if the acquisition had been completed on April 1, 2012. The pro forma results were calculated by combining the results of ATK with the stand-alone results of Bushnell for the pre-acquisition periods, which were adjusted to account for certain costs which would have been incurred during this pre-acquisition period:

	QUARTERS ENDED				NINE MONTHS ENDED

Diluted earnings per common share	2.31		1.89		8.61		5.86

Business Acquisition, Pro Forma Information, Nonrecurring Adjustments [Table Text Block]

The unaudited supplemental pro forma data above include the following significant non-recurring adjustments made to account for certain costs which would have been incurred if the acquisition had been completed on April 1, 2012, as adjusted for the applicable tax impact:

	QUARTERS ENDED					NINE MONTHS ENDED
(Amounts in thousands)	December 29, 2013			December 30, 2012		December 29, 2013			December 30, 2012
Inventory Step-up, net1	$	(847	)	$	—	$	(847	)	$	2,153
ATK/Bushnell fees for advisory, legal, accounting services2	(8,369		)	—		(11,031		)	11,031

1. Adjustment reflects the increased cost of goods sold expense which results from the fair value step-up in inventory of $3,500 which was expensed over the first inventory cycle.

2. Removed the ATK/Bushnell fees that were incurred in connection with the acquisition of Bushnell from fiscal 2014, and considered those fees as incurred during the first quarter of fiscal 2013.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

ATK’s provision for income taxes includes federal, foreign, and state income taxes. Income tax provisions for interim periods are based on estimated effective annual income tax rates.

The income tax provisions for the quarters ended December 29, 2013 and December 30, 2012 represent effective tax rates of 32.7% and 31.9%, respectively. The increase in the rate from the prior year quarter is primarily due to current year nondeductible acquisition-related costs and decreased benefits from the domestic manufacturing deduction, partially offset by the favorable true-up of prior-year taxes and the retroactive extension of the research and development credit ("R&D credit") that occurred after the prior year quarter.

The income tax provisions for the nine months endedDecember 29, 2013 and December 30, 2012 represent effective tax rates of 32.7% and 30.0%, respectively. The increase in the rate from the prior year period is primarily due to the prior year period settlement of the examination by the Internal Revenue Service ("IRS") of the fiscal 2009 and 2010 tax returns and nondeductible acquisition-related costs, partially offset by the revaluation of unrecognized tax benefits due to proposed IRS regulations enacted in the second quarter of the current fiscal year.

The IRS released final regulations relating to the capitalization of tangible personal property on September 13, 2013. ATK is currently analyzing the impact of these new regulations. We do not believe they will have a material impact on our financial statements.

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 2007. The IRS has completed the audits of ATK through fiscal 2010 and is currently auditing ATK's tax returns for fiscal years 2011 and 2012. We believe appropriate provisions for all outstanding issues have been made for all remaining open years in all jurisdictions.

Although the timing and outcome of audit settlements are uncertain, it is reasonably possible that a $4,686 reduction of the uncertain tax benefits will occur in the next 12 months. The settlement of these unrecognized tax benefits could result in earnings from $0 to $4,294.

Loss Contingency [Abstract]

Contingencies

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, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings in any particular quarter, 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 July 30, 2013, Raytheon Company filed a lawsuit against ATK in the Superior Court of the State of Arizona.  The suit involves ATK's longstanding production of rocket motors used in Raytheon's Advanced Medium-Range Air-to-Air Missiles (AMRAAM).  In the filing, Raytheon's primary allegation is that ATK breached certain of the production contracts by not delivering rocket motors.  Raytheon is claiming damages exceeding $100,000.

ATK disputes the allegations of Raytheon's complaint. Although it is not possible at this time to predict the outcome of the litigation, ATK believes, based on all currently available information, that the outcome will not have a material adverse effect on its operating results, financial condition 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.

Claim Recovery.    Profits expected to be realized on contracts are based on management'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. At December 29, 2013, based on progress to date on certain contracts, there is approximately $34,490 included in unbilled receivables for contract claims compared to $27,797 as of March 31, 2013.

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 0.8% as of December 29, 2013 and March 31, 2013, 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:

	December 29, 2013						March 31, 2013
	Liability			Receivable			Liability			Receivable
Amounts (payable) receivable	$	(52,949	)	$	28,685		$	(61,227	)	$	35,638
Unamortized discount	5,863			(2,704		)	3,731			(1,925		)
Present value amounts (payable) receivable	$	(47,086	)	$	25,981		$	(57,496	)	$	33,713

Amounts expected to be paid or received in periods more than one year from the balance sheet date are classified as non-current. Of the $47,086 discounted liability as of December 29, 2013, $5,049 was recorded within other current liabilities and $42,037 was recorded within other long-term liabilities. Of the $25,981 discounted receivable, ATK recorded $4,650 within other current assets and $21,331 within other non-current assets. As of December 29, 2013, the estimated discounted range of reasonably possible costs of environmental remediation was $47,086 to $75,526.

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 in Note 13 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013.

ATK has been identified as a potentially responsible party (“PRP”), along with other parties, in several regulatory agency actions associated with hazardous waste sites. As a PRP, we may be required to pay a share of the costs of the investigation and clean-up of these sites. While uncertainties exist with respect to the amounts and timing of the ultimate environmental liabilities, based on currently available information, we have concluded that these matters, individually or in the aggregate, will not have a material adverse effect on our operating results, financial condition, or cash flows.

Business Combinations [Abstract]

Acquisitions

Acquisitions

In accordance with the accounting standards regarding business combinations, the results of acquired businesses are included in ATK’s consolidated financial statements from the date of acquisition. For each acquisition, the purchase price 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.

Savage Acquisition

On June 21, 2013, ATK acquired Caliber Company, parent company of Savage Sports Corporation ("Savage"), a leading manufacturer of sporting long guns. Operating under the brand names of Savage Arms, Stevens and Savage Range Systems, the company designs, manufactures and markets centerfire and rimfire rifles, shotguns and shooting range systems used for hunting as well as competitive and recreational target shooting. The purchase price was $315,000 net of cash acquired, and is subject to purchase price adjustments expected to be settled in fiscal 2014. ATK believes the acquisition complements ATK's growing portfolio of leading consumer brands and will allow us to build upon our offerings with Savage's prominent, respected brands known for accuracy, quality, innovation, value and craftsmanship. Savage's sales distribution channels, new product development, and sophistication in manufacturing will significantly increase ATK's presence with a highly relevant product offering to distributors, retailers and consumers. Savage employs approximately 600 employees and is included in the Sporting Group. The purchase price allocation will be completed in fiscal 2014. None of the goodwill generated in this acquisition will be deductible for tax purposes.

ATK used the acquisition method of accounting to account for this acquisition and, accordingly, the results of Savage are included in ATK’s consolidated financial statements at the date of acquisition. The purchase price for the acquisition has been preliminarily allocated to the acquired assets and liabilities based on estimated fair value. The preliminary purchase price allocation is subject to further refinement and may require significant adjustments to arrive at the final purchase price allocation. These adjustments will primarily relate to intangible asset valuation, certain contingent liabilities and income tax-related items. We expect the purchase price allocation to be completed within 12 months of the acquisition date. Pro forma information on the results of operations for fiscal 2013 as if the acquisition had occurred at the beginning of fiscal 2013 is not being presented because the acquisition is not material to ATK for that purpose. Subsequent to June 21, 2013, ATK has recorded sales of approximately $116,908 for fiscal year 2014 and $53,920 for the quarter ended December 29, 2013 and income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest of approximately $18,887 for fiscal year 2014 and $13,266 for the quarter ended December 29, 2013 associated with the operations of this acquired business, which reflects the expense of the inventory step-up cost of $9,000 for inventory sold in fiscal year 2014 and none for inventory sold in the quarter ended December 29, 2013.

Bushnell Acquisition

On November 1, 2013, ATK acquired Bushnell Group Holdings, Inc. ("Bushnell"). Bushnell is a leading global designer, marketer and distributor of branded sports optics, outdoor accessories and performance eyewear. The purchase price was $985,000 net of cash acquired, subject to purchase price adjustments. ATK believes the acquisition broadens our existing capabilities in the commercial shooting sports market and expands our portfolio of branded shooting sports products. In addition, this transaction enables the Company to enter new sporting markets in golf and snow skiing. ATK will leverage Bushnell’s strong sourcing, marketing, branding and distribution capabilities and capitalize on Bushnell’s track record of successfully integrating acquisitions and delivering profitable growth. Bushnell employs approximately 1,100 employees and is included in the Sporting Group. The purchase price has been preliminarily allocated based on the estimated fair value of net assets acquired and liabilities assumed at the date of the acquisition. The preliminary purchase price allocation is subject to further refinement and may require significant adjustments to arrive at the final purchase price allocation. These adjustments will primarily relate to intangible asset valuation, certain contingent liabilities and income tax-related items. We expect the purchase price allocation to be completed within 12 months of the acquisition date. A portion of the goodwill generated in this acquisition will be deductible for tax purposes. Subsequent to November 1, 2013, ATK has recorded sales of approximately $85,074 for the quarter and nine months ended December 29, 2013 and income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest of approximately $3,123 for the quarter and nine months ended December 29, 2013 associated with the operations of this acquired business which reflects transition costs and $1,377 of inventory step-up costs. The income before interest, loss on extinguishment of debt, income taxes, and noncontrolling interest excludes transaction costs of $10,200 for the quarter ended December 29, 2013.

Preliminary Allocation of Consideration Transferred to Net Assets Acquired:

The following amounts represent the preliminary determination of the fair value of identifiable assets acquired and liabilities assumed from the Bushnell acquisition. The final determination of the fair value of certain assets and liabilities will be completed within the 12-month measurement period from the date of acquisition as required. The size and breadth of the Bushnell acquisition will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the asset and liability fair values as of the acquisition date, including the significant contractual and operational factors underlying the trade name and customer relationship intangible assets, the assumptions utilized on certain reserves such as those for inventory obsolescence, the assumptions used in transfer pricing analysis, and the related tax impacts of any changes made. Any potential adjustments made could be material in relation to the preliminary values presented below:

Purchase Price net of cash acquired:
Cash Paid			$	985,000
Cash Paid for additional working capital			4,065
Total purchase price			$	989,065

Other liabilities	27,263
Total liabilities	$	186,484
Net assets acquired			$	484,744

Supplemental Pro Forma Data:

ATK used the acquisition method of accounting to account for this acquisition and, accordingly, the results of Bushnell are included in ATK’s consolidated financial statements for the period subsequent to the date of acquisition. The following unaudited supplemental pro forma data for the quarter and nine months ended December 29, 2013 and December 30, 2012 present consolidated information as if the acquisition had been completed on April 1, 2012. The pro forma results were calculated by combining the results of ATK with the stand-alone results of Bushnell for the pre-acquisition periods, which were adjusted to account for certain costs which would have been incurred during this pre-acquisition period:

	QUARTERS ENDED				NINE MONTHS ENDED
(Amounts in thousands except per share data)	December 29, 2013		December 30, 2012		December 29, 2013		December 30, 2012

Basic earnings per common share	2.39		1.90		8.80		5.89
Diluted earnings per common share	2.31		1.89		8.61		5.86

The unaudited supplemental pro forma data above include the following significant non-recurring adjustments made to account for certain costs which would have been incurred if the acquisition had been completed on April 1, 2012, as adjusted for the applicable tax impact:

	QUARTERS ENDED					NINE MONTHS ENDED
(Amounts in thousands)	December 29, 2013			December 30, 2012		December 29, 2013			December 30, 2012
Inventory Step-up, net1	$	(847	)	$	—	$	(847	)	$	2,153
ATK/Bushnell fees for advisory, legal, accounting services2	(8,369		)	—		(11,031		)	11,031

1. Adjustment reflects the increased cost of goods sold expense which results from the fair value step-up in inventory of $3,500 which was expensed over the first inventory cycle.

2. Removed the ATK/Bushnell fees that were incurred in connection with the acquisition of Bushnell from fiscal 2014, and considered those fees as incurred during the first quarter of fiscal 2013. Costs were recorded in General and administrative expense.

There were no acquisitions during fiscal 2013.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The current authoritative guidance on fair value 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. Fair value is defined 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 the current authoritative literature 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.

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 which are used to pay benefits under a nonqualified supplemental executive retirement plan for certain executives and highly compensated employees. 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. The fair value of these securities is included within other current assets and deferred charges and other non-current assets on the consolidated balance sheet.

Derivative financial instruments and hedging activities—In order to manage its exposure to commodity pricing, interest rate risk, and foreign currency risk, ATK periodically utilizes commodity, interest rate, and foreign currency derivatives, which are considered Level 2 instruments. As discussed further in Note 7, ATK has outstanding commodity forward contracts that were entered into to hedge forecasted purchases of copper and zinc. Commodity derivatives are valued based on prices of futures exchanges and recently reported transactions in the marketplace. During fiscal 2014, ATK entered into five interest rate swaps. These swaps are valued based on future LIBOR rates and the established fixed rate is based primarily on quotes from banks. Foreign currency derivatives are valued based on observable market transactions of spot currency rates and forward currency prices. No foreign currency derivatives were outstanding as of December 29, 2013.

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. We have considered these to be Level 2 instruments.

The following table sets forth by level within the fair value hierarchy ATK's financial assets and liabilities that are measured at fair value on a recurring basis:

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 December 29, 2013, ATK has authorized up to 3,982,360 common shares under the 2005 Stock Incentive Plan, of which 1,325,135 common shares are available to be granted. No new grants will be made out of the other three plans. Furthermore, as of December 29, 2013, no awards remained outstanding under the 2000 Stock Incentive Plan.

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 December 29, 2013, there were up to 418,836 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:

• up to 221,062 shares will become payable only upon achievement of certain financial performance goals, including sales and return on invested capital for the fiscal 2012 through fiscal 2014 period;

• up to 102,848 shares will become payable only upon achievement of certain performance goals, including sales and return on invested capital, for the fiscal 2013 through fiscal 2015 period; and

• up to 94,926 shares will become payable only upon achievement of certain performance goals, including sales and return on invested capital, for the fiscal 2014 through fiscal 2016 period.

There were 35,852 shares earned during fiscal 2013 upon achievement of certain financial performance goals, including EPS, for the fiscal 2011 through fiscal 2013 period, which were distributed or deferred in May 2013. As other financial performance goals were not met, 155,359 shares were forfeited during fiscal 2013.

As of December 29, 2013, there were up to 45,980 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. 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 of 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. There were no TSR awards granted during the nine months endedDecember 29, 2013.

Of the shares reserved for TSR awards for key employees,

• 45,980 shares will become payable upon satisfaction of the market conditions stipulated for the fiscal 2012 through 2014 period.

No shares were earned during fiscal 2013 as the market conditions stipulated for the fiscal 2011 through 2013 period were not satisfied and, as such, 26,000 TSR awards were forfeited during fiscal 2013.

Restricted stock granted to non-employee directors and certain key employees totaled 80,834 shares during the nine months endedDecember 29, 2013. Restricted shares vest over periods generally ranging from one to three 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. Options are generally granted with seven-year or ten-year terms. 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 seven 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. The weighted average fair value of options granted was $23.00 during the nine months endedDecember 29, 2013. There were no stock options granted during the nine months endedDecember 30, 2012. The following weighted average assumptions were used for grants:

	Nine Months ended December 29, 2013
Risk-free rate	1.86%
Expected volatility	25.95%
Expected dividend yield	1.58%
Expected option life	7 years

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

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 currency 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.

ATK entered into forward contracts for copper and zinc during fiscal 2014 and 2013. The contracts essentially establish a fixed price for the underlying commodity and are designated and qualify as effective cash flow hedges of purchases of the commodity. Ineffectiveness is calculated as the amount by which the change in the fair value of the derivatives exceeds the change in the fair value of the anticipated commodity purchases.

ATK entered into interest rate swaps in the second and third quarters of fiscal 2014 whereby we pay a fixed rate on a total notional amount of $400,000 and receive one-month LIBOR. The fair value of interest rate swap agreements approximates the amount at which they could be settled, based on estimates obtained from the counterparties. We perform assessments of the effectiveness of our hedge instruments on a quarterly basis and during fiscal 2014 determined the hedges to be highly effective. The counterparties to the interest rate swap agreements expose us to credit risk in the event of nonperformance. However, at December 29, 2013, three of the outstanding swap agreements were in a net liability position which would require us to make the net settlement payments to the counterparties, and two of the outstanding swap agreements were in a net asset position which would require the counterparties to make the net settlement payments to ATK. We do not anticipate nonperformance by our counterparties. We do not hold or issue derivative financial instruments for trading purposes.

ATK has not entered into any foreign currency forward contracts during fiscal 2014 or 2013. Contracts entered into prior to fiscal 2013 were used to hedge forecasted inventory purchases and subsequent payments, or customer receivables, denominated in foreign currencies and were designated and qualified as effective cash flow hedges. Ineffectiveness with respect to forecasted inventory purchases was calculated based on changes in the forward rate until the anticipated purchase occurs; ineffectiveness of the hedge of the accounts payable was evaluated based on the change in fair value of its anticipated settlement.

The fair value of the commodity, interest rate, and foreign currency forward contracts are recorded within other assets or liabilities, as appropriate, and the effective portion is reflected in accumulated Other Comprehensive Income (Loss) in the financial statements. The gains or losses on the commodity forward contracts are recorded in inventory as the commodities are purchased. The gains or losses on the foreign currency forward contracts are recorded in earnings when the related inventory is sold. The gains or losses on the interest rate swaps are recorded in interest expense when the interest payments are made.

As of December 29, 2013, ATK had the following outstanding commodity forward contracts that were entered into to hedge forecasted purchases:

	Number of Pounds
Copper	15,252,000
Zinc	5,478,000

As of December 29, 2013, ATK had three outstanding interest rate swaps with notional amounts of $100,000 each with maturity dates in August 2016, 2017, and 2018, as well as two interest rate swaps with notional amounts of $50,000 each with maturity dates in November 2016 and 2017. See footnote 12 for additional information.

As of December 29, 2013, ATK had no outstanding foreign currency forward contracts in place.

The table below presents the fair value and location of ATK's derivative instruments designated as hedging instruments in the consolidated balance sheet as of the periods presented.

		Asset Derivatives Fair value as of				Liability Derivatives Fair value as of

Due to the nature of ATK's business, the benefits associated with the commodity contracts may be passed on to the customer and not realized by ATK.

For the periods presented below, the derivative gains and losses in the consolidated income statements related to commodity forward contracts, interest rate swaps, and foreign currency forward contracts were as follows:

All derivatives used by ATK during the periods presented were designated as hedging instruments.

During the quarter and nine months ended December 29, 2013 there was a loss of $0 and $1,637, respectively, recognized in earnings as a result of ineffectiveness on forward contracts for copper and zinc. ATK expects that the remaining unrealized losses will be realized and reported in cost of sales as the cost of the commodities is included in cost of sales. Estimated and actual gains or losses will change as market prices change.

Earnings Per Share [Abstract]

Earnings Per Share Data

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 and contingently issuable shares related to ATK's Convertible Senior Subordinated Notes (see Note 12) during each period presented, which, if exercised, earned, or converted, would have a dilutive effect on EPS. In computing EPS for the quarter and nine months ended December 29, 2013 and December 30, 2012 earnings, as reported for each respective period, is divided by (in thousands):

	Quarters Ended		Nine months ended
	December 29, 2013	December 30, 2012	December 29, 2013	December 30, 2012
Basic EPS shares outstanding	31,536	32,454	31,701	32,493

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	3	150	3	151

As discussed further in Note 12, contingently issuable shares related to ATK’s 3.00% Convertible Senior Subordinated Notes due 2024 are not included in diluted EPS for the three or nine months ended December 30, 2012 because ATK’s average stock price during these periods did not exceed the triggering price.

Changes in Estimates [Abstract]

Changes in Estimates

Changes in Estimates

The majority of ATK’s sales are accounted for as long-term contracts, which are accounted for under the percentage-of-completion method (“POC”). Accounting for contracts under the POC method requires judgment relative to assessing risks and estimating contract revenues and costs. Profits expected to be realized on contracts are based on management’s estimates of total contract sales value and costs at completion. Estimated amounts for contract changes, including scope 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. Changes in estimates of contract sales, costs, or profits are recognized using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on current or prior periods. The effect of the changes on future periods of contract performance is recognized as if the revised estimate had been used since contract inception.

Changes in contract estimates occur for a variety of reasons including changes in contract scope, unforeseen changes in contract cost estimates, positive or negative, due to unanticipated cost growth or risks affecting contract costs and/or the resolution of contract risks at lower costs than anticipated, as well as changes in contract overhead costs over the performance period. Changes in estimates could have a material effect on the Company’s consolidated financial position or annual results of operations. Aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting increased operating income by $19,657 and $28,904 for the quarters ended December 29, 2013 and December 30, 2012, respectively. The current quarter adjustments were primarily driven by higher profit expectations in the Small Caliber Systems and Armament Systems divisions. The prior year quarter adjustments were primarily driven by changes in estimates in Small-Caliber Systems and Space System Operations offset by a reduction in Armament Systems divison.

Aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting increased operating income by $86,937 and $101,532 for the nine months endedDecember 29, 2013 and December 30, 2012, respectively. The current year nine-month period adjustments were primarily driven by higher profit expectations of $39,125 in the Small Caliber Systems division due to operational efficiencies, a successful in-sourcing initiative, and reduced operational risk as a contract nears completion, and for programs in the Space Systems Operations and Aerospace Structures divisions. The prior year nine-month period adjustments were primarily driven by changes in estimates in Small Caliber Systems and Energetic Systems as contracts near completion, and changes in estimates in Space System Operations due to performance improvements.

(1) On November 1, 2013, ATK entered into a Third Amended and Restated Credit Agreement (the "2013 Senior Credit Facility"), which replaced its 2010 Senior Credit Facility. The 2013 Senior Credit Facility is comprised of a Term A Loan of $1,010,000 and a $700,000 Revolving Credit Facility, both of which mature in 2018, and a Term Loan B of $250,000, which matures in 2020. The Term A Loan is subject to quarterly principal payments of $12,625 beginning on March 31, 2014, with the remaining balance due on November 1, 2018. The Term B Loan is subject to quarterly principal payments of $625 beginning on March 31, 2014, with the remaining balance due on November 1, 2020. Substantially all domestic tangible and intangible assets of ATK and its subsidiaries are pledged as collateral under the 2013 Senior Credit Facility. Borrowings under the 2013 Senior Credit Facility bear interest at a rate equal to either the sum of a base rate plus a margin or the sum of a Eurodollar rate plus a margin. Each margin is based on ATK's senior secured credit ratings. Based on ATK's current credit rating, the current base rate margin is 1.00% and the current Eurodollar margin is 2.00%. The weighted average interest rate for the Term A Loan, after taking into account the interest rate swaps discussed below, was 2.60% at December 29, 2013. ATK pays an annual commitment fee on the unused portion of the Revolving Credit Facility based on its senior secured credit ratings. Based on ATK's current rating, this current fee is 0.30%. As of December 29, 2013, ATK had no borrowings against its $700,000 Revolving Credit Facility and had outstanding letters of credit of $124,554, which reduced amounts available on the Revolving Credit Facility to $575,446. Debt issuance costs totaling approximately $19,000 will be amortized over the term of each related Term Loan.

In fiscal 2011, ATK entered into a Second Amended and Restated Credit Agreement (the "2010 Senior Credit Facility"), which was comprised of a Term A Loan of $400,000 and a $600,000 Revolving Credit Facility, both of which were to mature in 2015. During the third quarter of fiscal 2014, the Company refinanced this agreement as noted above. The transaction resulted in the write-off of the remaining $6,166 of unamortized debt issuance costs in the quarter ended December 29, 2013.

(2) On November 1, 2013, ATK issued $300,000 aggregate principal amount of 5.25% Senior Notes (the "5.25% Notes") that mature on October 1, 2021. These notes are general unsecured obligations. Interest on these notes is payable 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 October 1, 2016, at specified redemption prices. Prior to October 1, 2016, 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 October 1, 2016, ATK may redeem up to 35% of the aggregate principal amount of these notes with the net cash proceeds of certain equity offerings, at a price equal to 105.25% of their principal amount plus accrued and unpaid interest to the date of redemption. Debt issuance costs of approximately $3,000 related to these notes will be amortized to interest expense over the term of the notes.

(3) In fiscal 2011, ATK issued $350,000 aggregate principal amount of 6.875% Senior Subordinated Notes ("the 6.875% Notes") that mature on September 15, 2020. These notes are general unsecured obligations. Interest on these notes is payable on March 15 and September 15 of each year. ATK has the right to redeem some or all of these notes from time to time on or after September 15, 2015, at specified redemption prices. Prior to September 15, 2015, 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. Debt issuance costs of approximately $7,100 related to these notes are being amortized to interest expense over 10 years.

(4) 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. Under select conditions, ATK will pay contingent interest on these notes, which is treated as an embedded derivative; the fair value of this feature was insignificant at December 29, 2013 and March 31, 2013. ATK may redeem some or all of these notes in cash, for 100% of the principal amount plus any accrued but unpaid interest, at any time on or after August 20, 2014. Holders of these notes may require ATK to repurchase in cash, for 100% of the principal amount plus any accrued but unpaid interest, some or all of these notes on August 15, 2014 and August 15, 2019. Under specified conditions (including if, during any fiscal quarter, the last reported sale price of ATK’s common stock is greater than or equal to 130% of the conversion price 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), holders may also convert their 3.00% Convertible Notes into shares of ATK’s common stock. These notes had an initial conversion rate of 12.5392 shares per $1 principal amount (a conversion price of $79.75). Pursuant to provisions in the indenture requiring adjustment of the conversion rate upon the payment of dividends, the conversion rate for these notes is now 13.0717, which correspondingly has changed the conversion price per share to $76.50. The stock price condition was met during the quarter ended December 29, 2013; accordingly, the notes are now convertible at any time, at the option of the holder, through March 31, 2014, and will remain convertible so long as ATK’s stock price continues to meet the 130%-of-conversion-price condition, as described above. The stock price condition was also met in fiscal 2009 and $547 of these notes were converted. Because the notes are now convertible and also will be putable within the next year, the remaining principal amount of $199,453 is classified as short-term. The convertible shares had an impact on diluted shares outstanding for the quarter and nine-month periods ended December 29, 2013 of 821,000 and 476,000, respectively, because ATK's average stock price exceeded the conversion price during those periods. These shares had no impact on the diluted shares outstanding for the quarter and nine-month period ended December 30, 2012 as the average stock price did not exceed the conversion price during those periods.

(1) On November 1, 2013, ATK entered into a Third Amended and Restated Credit Agreement (the "2013 Senior Credit Facility"), which replaced its 2010 Senior Credit Facility. The 2013 Senior Credit Facility is comprised of a Term A Loan of $1,010,000 and a $700,000 Revolving Credit Facility, both of which mature in 2018, and a Term Loan B of $250,000, which matures in 2020. The Term A Loan is subject to quarterly principal payments of $12,625 beginning on March 31, 2014, with the remaining balance due on November 1, 2018. The Term B Loan is subject to quarterly principal payments of $625 beginning on March 31, 2014, with the remaining balance due on November 1, 2020. Substantially all domestic tangible and intangible assets of ATK and its subsidiaries are pledged as collateral under the 2013 Senior Credit Facility. Borrowings under the 2013 Senior Credit Facility bear interest at a rate equal to either the sum of a base rate plus a margin or the sum of a Eurodollar rate plus a margin. Each margin is based on ATK's senior secured credit ratings. Based on ATK's current credit rating, the current base rate margin is 1.00% and the current Eurodollar margin is 2.00%. The weighted average interest rate for the Term A Loan, after taking into account the interest rate swaps discussed below, was 2.60% at December 29, 2013. ATK pays an annual commitment fee on the unused portion of the Revolving Credit Facility based on its senior secured credit ratings. Based on ATK's current rating, this current fee is 0.30%. As of December 29, 2013, ATK had no borrowings against its $700,000 Revolving Credit Facility and had outstanding letters of credit of $124,554, which reduced amounts available on the Revolving Credit Facility to $575,446. Debt issuance costs totaling approximately $19,000 will be amortized over the term of each related Term Loan.

In fiscal 2011, ATK entered into a Second Amended and Restated Credit Agreement (the "2010 Senior Credit Facility"), which was comprised of a Term A Loan of $400,000 and a $600,000 Revolving Credit Facility, both of which were to mature in 2015. During the third quarter of fiscal 2014, the Company refinanced this agreement as noted above. The transaction resulted in the write-off of the remaining $6,166 of unamortized debt issuance costs in the quarter ended December 29, 2013.

(2) On November 1, 2013, ATK issued $300,000 aggregate principal amount of 5.25% Senior Notes (the "5.25% Notes") that mature on October 1, 2021. These notes are general unsecured obligations. Interest on these notes is payable 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 October 1, 2016, at specified redemption prices. Prior to October 1, 2016, 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 October 1, 2016, ATK may redeem up to 35% of the aggregate principal amount of these notes with the net cash proceeds of certain equity offerings, at a price equal to 105.25% of their principal amount plus accrued and unpaid interest to the date of redemption. Debt issuance costs of approximately $3,000 related to these notes will be amortized to interest expense over the term of the notes.

(3) In fiscal 2011, ATK issued $350,000 aggregate principal amount of 6.875% Senior Subordinated Notes ("the 6.875% Notes") that mature on September 15, 2020. These notes are general unsecured obligations. Interest on these notes is payable on March 15 and September 15 of each year. ATK has the right to redeem some or all of these notes from time to time on or after September 15, 2015, at specified redemption prices. Prior to September 15, 2015, 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. Debt issuance costs of approximately $7,100 related to these notes are being amortized to interest expense over 10 years.

(4) 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. Under select conditions, ATK will pay contingent interest on these notes, which is treated as an embedded derivative; the fair value of this feature was insignificant at December 29, 2013 and March 31, 2013. ATK may redeem some or all of these notes in cash, for 100% of the principal amount plus any accrued but unpaid interest, at any time on or after August 20, 2014. Holders of these notes may require ATK to repurchase in cash, for 100% of the principal amount plus any accrued but unpaid interest, some or all of these notes on August 15, 2014 and August 15, 2019. Under specified conditions (including if, during any fiscal quarter, the last reported sale price of ATK’s common stock is greater than or equal to 130% of the conversion price 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), holders may also convert their 3.00% Convertible Notes into shares of ATK’s common stock. These notes had an initial conversion rate of 12.5392 shares per $1 principal amount (a conversion price of $79.75). Pursuant to provisions in the indenture requiring adjustment of the conversion rate upon the payment of dividends, the conversion rate for these notes is now 13.0717, which correspondingly has changed the conversion price per share to $76.50. The stock price condition was met during the quarter ended December 29, 2013; accordingly, the notes are now convertible at any time, at the option of the holder, through March 31, 2014, and will remain convertible so long as ATK’s stock price continues to meet the 130%-of-conversion-price condition, as described above. The stock price condition was also met in fiscal 2009 and $547 of these notes were converted. Because the notes are now convertible and also will be putable within the next year, the remaining principal amount of $199,453 is classified as short-term. The convertible shares had an impact on diluted shares outstanding for the quarter and nine-month periods ended December 29, 2013 of 821,000 and 476,000, respectively, because ATK's average stock price exceeded the conversion price during those periods. These shares had no impact on the diluted shares outstanding for the quarter and nine-month period ended December 30, 2012 as the average stock price did not exceed the conversion price during those periods.

The current authoritative accounting literature requires that issuers of convertible debt instruments that may be settled in cash upon conversion separately account for the liability and equity components in a manner that reflects the entity’s nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. This provision applies to the convertible debt instrument discussed above.

The unamortized discount is amortized through interest expense into earnings over the expected term of the convertible notes. The following table provides additional information about ATK’s 3.00% Convertible Notes:

	December 29, 2013			March 31, 2013
Carrying amount of the equity component	$	56,849		$	56,849
Principal amount of the liability component	$	199,453		$	199,453
Unamortized discount of liability component	$	5,095		$	10,576
Net carrying amount of liability component	$	194,358		$	188,877
Remaining amortization period of discount	128			137
Effective interest rate on liability component	7.000		%	7.000		%

Based on ATK's closing stock price of $122.05 on December 29, 2013, the if-converted value of these notes exceeded the aggregate principal amount of the notes by $118,755.

Interest Rate Swaps

During fiscal 2014, ATK entered into five floating-to-fixed interest rate swap agreements in order to manage interest costs and the risk associated with variable interest rates. As of December 29, 2013, ATK had the following cash flow hedge interest rate swaps in place:

	Notional		Fair Value			Pay Fixed		Receive Floating		Maturity Date
Non-amortizing swap	$	100,000	$	(661	)	0.87	%	0.16	%	August 2016
Non-amortizing swap	$	100,000	$	(805	)	1.29	%	0.16	%	August 2017
Non-amortizing swap	$	100,000	$	(820	)	1.69	%	0.16	%	August 2018
Non-amortizing swap	$	50,000	$	146		0.65	%	0.16	%	November 2016
Non-amortizing swap	$	50,000	$	193		1.10	%	0.16	%	November 2017

The amount to be paid or received under these swaps is recorded as an adjustment to interest expense.

See Note 9 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013 for additional information regarding the terms and conditions of the Company’s outstanding debt agreements.

Rank and Guarantees

The 5.25% Notes rank senior in right of payment to the 3.00% Convertible Notes and the 6.875% Notes (the latter two of which rank equal with each other), all of which are subordinated in right of payment to all existing and future senior secured 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. The parent company has no independent assets or operations. As a result of the acquisition of Bushnell during the third quarter, ATK's non-guarantor subsidaries become more than minor. See footnote 20 for consolidating financial information of the guarantor and non-guarantor subsidiaries. All of these guarantor subsidiaries are 100% owned by ATK. These guarantees are senior or senior subordinated obligations, as applicable, of the applicable subsidiary guarantors. The guarantee by any Subsidiary Guarantor of ATK’s obligations in respect of the 5.25% Notes and the 6.875% Notes will be released in each of the following circumstances:

• if, as a result of the sale of its capital stock, such Subsidiary Guarantor ceases to be a Restricted Subsidiary;

• if such Subsidiary Guarantor is designated as an “Unrestricted Subsidiary”;

• upon defeasance or satisfaction and discharge of the 5.25% Notes or the 6.875% Notes, as applicable; and

• if such Subsidiary Guarantor has been released from its guarantees of indebtedness under the Credit Agreement and all capital markets debt securities.

The guarantee by any Subsidiary Guarantor of the Company’s obligations in respect of the 3.00% Convertible Notes due 2024 will be released if such Subsidiary Guarantor is released from its guarantee of the 5.25% Notes and the 6.875% Notes.

Scheduled Minimum Loan Payments

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

Remainder of fiscal 2014	$	13,250
Fiscal 2015	252,453
Fiscal 2016	53,000
Fiscal 2017	53,000
Fiscal 2018	53,000
Thereafter	1,684,750
Total	$	2,109,453

ATK's total debt (current portion of debt and long-term debt) as a percentage of total capitalization (total debt and stockholders' equity) was 55% and 42% as of December 29, 2013 and March 31, 2013, respectively.

Covenants and Default Provisions

ATK's Senior Credit Facility and the indentures governing the 5.25% Notes, the 6.875% Notes, 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. ATK’s 5.25% Notes and its 6.875% 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 December 29, 2013, this limit was approximately $839,000. The 2013 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 a certain amount of liquidity and maintains certain senior debt limits, with a limit, when those senior debt limits are not met, of $250,000 plus proceeds of any equity issuances plus 50% of net income since October 7, 2010. The Senior Credit Facility also requires that ATK meet and maintain specified financial ratios, including a minimum interest coverage ratio, a maximum consolidated senior leverage ratio, and a maximum consolidated leverage ratio. Many of ATK's debt agreements contain cross-default provisions so that non-compliance with the covenants within one debt agreement could cause a default under other debt agreements as well. 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 2013 Senior Credit Facility are subject to compliance with these covenants. As of December 29, 2013, ATK was in compliance with the financial covenants.

Cash Paid for Interest on Debt

Cash paid for interest totaled $27,757 in the nine months ended December 29, 2013, and $45,931 in the nine months ended December 30, 2012.
