	(1) Organization:
	We are one of the world’s leading manufacturers of firearms. We manufacture a wide array of handguns (including revolvers and pistols), long guns (including modern sporting, bolt action, and single shot rifles), handcuffs, and firearm-related products and accessories for sale to a wide variety of customers, including gun enthusiasts, collectors, hunters, sportsmen, competitive shooters, individuals desiring home and personal protection, law enforcement and security agencies and officers, and military agencies in the United States and throughout the world. We are one of the largest manufacturers of handguns, modern sporting rifles, and handcuffs in the United States and an active participant in the hunting rifle market. We sell our products under the Smith & Wesson®, M&P®, and Thompson/Center ArmsTM brands.
	We manufacture our firearm products at our facilities in Springfield, Massachusetts; Houlton, Maine; and Deep River, Connecticut. We plan to continue to offer products that leverage the over 160 year old “Smith & Wesson” brand and capitalize on the goodwill developed through our historic American tradition by expanding consumer awareness of the products we produce.
	On May 5, 2014, we purchased substantially all of the net assets of Tri Town Precision Plastics, Inc., or TTPP. See note 3 – Asset Purchase below for more information regarding this transaction.
	On November 25, 2014, we entered into a definitive agreement to acquire all the outstanding stock of Battenfeld Acquisition Company Inc., including its wholly owned subsidiary, Battenfeld Technologies, Inc., or BTI.

	(2) Basis of Presentation:
	Interim Financial Information - The consolidated balance sheet as of October 31, 2014, the consolidated statements of income for the three and six months ended October 31, 2014 and 2013, the consolidated statement of changes in stockholders’ equity for the six months ended October 31, 2014, and the consolidated statements of cash flows for the six months ended October 31, 2014 and 2013 have been prepared by us and are unaudited. In our opinion, all adjustments, which include only normal recurring adjustments necessary to fairly present the financial position, results of operations, changes in stockholders’ equity, and cash flows at October 31, 2014 and for the periods presented, have been included. All significant intercompany transactions have been eliminated in consolidation. The consolidated balance sheet as of April 30, 2014 has been derived from our audited consolidated financial statements.
	Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended April 30, 2014, filed with the SEC on June 19, 2014. The results of operations for the six months ended October 31, 2014 may not be indicative of the results that may be expected for the year ending April 30, 2015, or any other period.
	Discontinued Operations - SWSS LLC, formerly Smith & Wesson Security Solutions, Inc., or SWSS, our former security solutions division, is presented as discontinued operations in the consolidated statements of income for all periods presented. Unless stated otherwise, any reference to the consolidated statements of income items in the notes to the consolidated financial statements refers to results from continuing operations.
	Recently Issued Accounting Standards – In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606), or ASU 2014-09. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for interim reporting periods beginning October 1, 2017. Early adoption is not permitted. We are currently evaluating the impact, if any, that ASU 2014-09 will have on our consolidated financial statements.

Business Combinations [Abstract]	'
Asset Purchase	'
	(3) Asset Purchase:
	On May 5, 2014, we acquired substantially all of the net assets of TTPP for $24.1 million, including a $1.3 million working capital adjustment. We recorded this transaction in accordance with ASC 805-20, Business Combinations. TTPP was a provider of custom injection molding services, rapid prototyping and tooling, and was a long-standing supplier of polymer frames and related components for a large number of our firearms, including nearly all of our M&P models. Our acquisition of TTPP’s custom polymer injection molding capabilities was designed to vertically integrate a key component of our manufacturing operations providing us with increased flexibility within our supply chain.
	The initial estimated fair value asset and liability allocations made at the acquisition date were adjusted during the six months ended October 31, 2014 for inventory valuation and payroll accruals. We also recorded identifiable intangible assets relating to customer relationships and order backlog during the six months ended October 31, 2014. Additional information that existed as of the acquisition date but at that time was unknown may become known to us during the remainder of the measurement period, which will not exceed 12 months from the acquisition date. Adjustments in the purchase price allocation may require a recasting of the amounts allocated to goodwill retroactive to the period in which the acquisition occurred.
	The following table summarizes the estimated preliminary fair values of the assets acquired and liabilities assumed at the acquisition date, as well as measurement period adjustments as described above (in thousands):
		May 5, 2014 (As		Measurement

	Included in general and administrative costs is $442,000 of acquisition-related costs incurred during the six months ended October 31, 2014 related to the TTPP asset acquisition.
	Goodwill will be deductible for tax purposes and amortized over 15 years.
	We amortize customer relationships in proportion to expected yearly revenue generated from the customer lists acquired or products to be sold. We amortize order backlog over the contract lives as they are executed. The following are the identifiable intangible assets acquired and their respective estimated lives (dollars in thousands):
				Estimated Life
		Amount		(In years)
	Customer relationships	$	840		7
	Order backlog		150		1
		$	990
	Pro forma results of operations assuming that this acquisition had occurred on May 1, 2013 are not required because of the immaterial impact on our consolidated financial statements for all periods presented.

Debt Disclosure [Abstract]	'
Notes Payable and Financing Arrangements	'
	(4) Notes Payable and Financing Arrangements:
	Credit Facilities — As of October 31, 2014, we had a $75.0 million unsecured revolving credit facility that is expandable under an accordion feature that may be, in certain circumstances, increased in $25.0 million increments up to a maximum loan of $175.0 million. The credit facility matures on December 15, 2016 and bears interest at a variable rate equal to LIBOR or prime, at our election, plus an applicable margin based on our consolidated leverage ratio. As of October 31, 2014, there were no borrowings outstanding. Had there been borrowings, they would have borne an interest rate of 4.00% per annum if we had selected the prime rate option and a range of 1.90% to 2.07% per annum if we had selected the LIBOR rate option.
	On November 25, 2014, we amended our credit agreement with our lenders to expand our revolving credit facility to $125.0 million, in connection with entering into a definitive agreement to acquire BTI, leaving $50.0 million available under the accordion feature noted above. See Note 8 – Subsequent Events for more information regarding these transactions.
	5.875% Senior Notes — During fiscal 2014, we issued an aggregate of $47.1 million of 5.875% Senior Notes due 2017, or the 5.875% Senior Notes, to various qualified institutional buyers in exchange for approximately $42.8 million of our outstanding 9.5% senior notes due 2016, or the 9.5% Senior Notes, from existing holders of such notes. We also issued an additional $52.9 million of new 5.875% Senior Notes for cash. The remaining $712,000 of 9.5% Senior Notes outstanding after the exchange noted above were extinguished via legal defeasance during fiscal 2014. The 5.875% Senior Notes were sold pursuant to the terms and conditions of an indenture, or the 5.875% Senior Notes Indenture, and exchange and purchase agreements. The 5.875% Senior Notes bear interest at a rate of 5.875% per annum payable on June 15 and December 15 of each year, beginning on December 15, 2013. We recorded $4.3 million of interest expense related to bond premium and $795,000 of debt issuance write-off costs relating to the exchange and defeasance of the 9.5% Senior Notes during fiscal 2014.
	At any time prior to June 15, 2015, we may, at our option, (a) upon not less than 30 nor more than 60 days’ prior notice, redeem all or a portion of the 5.875% Senior Notes at a redemption price of 100% of the principal amount of the 5.875% Senior Notes, plus an applicable premium, plus accrued and unpaid interest as of the redemption date; or (b) redeem up to 35% of the aggregate principal amount of the 5.875% Senior Notes with the net cash proceeds of one or more equity offerings at a redemption price of 105.875% of the principal amount of the 5.875% Senior Notes, plus accrued and unpaid interest as of the redemption date; provided that in the case of the foregoing clause, at least 65% of the aggregate original principal amount of the 5.875% Senior Notes remains outstanding, and the redemption occurs within 60 days after the closing of the equity offering. On and after June 15, 2015, we may, at our option, upon not less than 30 nor more than 60 days prior notice, redeem all or a portion of the 5.875% Senior Notes at a redemption price of (a) 102.9375% of the principal amount of the 5.875% Senior Notes to be redeemed, if redeemed during the 12-month period beginning on June 15, 2015; or (b) 100% of the principal amount of the 5.875% Senior Notes to be redeemed, if redeemed during the 12-month period beginning on June 15, 2016, plus, in either case, accrued and unpaid interest on the 5.875% Senior Notes as of the applicable redemption date. Subject to certain restrictions and conditions, we may be required to make an offer to repurchase the 5.875% Senior Notes in connection with a change of control or disposition of assets. If not redeemed by us or repaid pursuant to the holders’ right to require repurchase, the 5.875% Senior Notes mature on June 15, 2017.
	The 5.875% Senior Notes are general, unsecured obligations of our company. The 5.875% Senior Notes Indenture contains certain affirmative and negative covenants, including limitations on restricted payments (such as share repurchases, dividends, and early payment of indebtedness), limitations on indebtedness, limitations on the sale of assets, and limitations on liens. Payments that would otherwise be characterized as restricted payments are permitted under the 5.875% Senior Notes Indenture in an amount not to exceed 50% of our consolidated net income for the period from the issue date to the date of the restricted payment, provided that at the time of making such payments, (a) no default has occurred or would result from the making of such payments, and (b) we are able to satisfy the debt incurrence test under the 5.875% Senior Notes Indenture, or the 5.875% Senior Notes Lifetime Aggregate Limit. In addition, the 5.875% Senior Notes Indenture provides for other exceptions to the restricted payments covenant, each of which are independent of the 5.875% Senior Notes Lifetime Aggregate Limit. Among such exceptions is the ability to make share repurchases each fiscal year in an amount not to exceed the lesser of (i) $30.0 million in any fiscal year or (ii) 75.0% of our consolidated net income for the previous four consecutive published fiscal quarters prior to the date of the determination of such consolidated net income. In addition, we purchased an additional $85.0 million of shares of our common stock in fiscal 2014 (including our $75.0 million tender offer), which purchases were permitted under various other exceptions.
	5.000% Senior Notes – During fiscal 2015, we issued an aggregate of $75.0 million of 5.000% Senior Notes due 2018, or the 5.000% Senior Notes, to various institutional investors pursuant to the terms and conditions of an indenture, or the 5.000% Senior Notes Indenture and collectively with the 5.875% Senior Notes Indenture, the Senior Notes Indentures, and purchase agreements. The 5.000% Senior Notes bear interest at a rate of 5.000% per annum payable on January 15 and July 15 of each year, beginning on January 15, 2015. We incurred $2.3 million of debt issuance costs related to the issuance of the 5.000% Senior Notes.
	At any time prior to July 15, 2016, we may, at our option (a) upon not less than 30 nor more than 60 days’ prior notice, redeem all or a portion of the 5.000% Senior Notes at the redemption price of 100% of the principal amount of the 5.000% Senior Notes, plus an applicable premium, plus accrued and unpaid interest as of the redemption date; or (b) redeem up to 35% of the aggregate principal amount of the 5.000% Senior Notes with the net cash proceeds of one or more equity offerings at a redemption price of 105.000% of the principal amount of the 5.000% Senior Notes, plus accrued and unpaid interest as of the redemption date; provided, that in the case of the foregoing clause, at least 65% of the aggregate original principal amount of the 5.000% Senior Notes remains outstanding, and the redemption occurs within 60 days after the closing of the equity offering. On and after July 15, 2016, we may, at our option, upon not less than 30 nor more than 60 days’ prior notice, redeem all or a portion of the 5.000% Senior Notes at the redemption price of (a) 102.500% of the principal amount of the 5.000% Senior Notes to be redeemed, if redeemed during the 12-month period beginning on July 15, 2016; or (b) 100% of the principal amount of the 5.000% Senior Notes to be redeemed, if redeemed during the 12-month period beginning on July 15, 2017, plus, in either case, accrued and unpaid interest on the 5.000% Senior Notes as of the applicable redemption date. Subject to certain restrictions and conditions, we may be required to make an offer to repurchase the 5.000% Senior Notes from the holders of the 5.000% Senior Notes in connection with a change of control or disposition of assets. If not redeemed by us or repaid pursuant to the holders’ right to require repurchase, the 5.000% Senior Notes mature on July 15, 2018.
	The 5.000% Senior Notes are general, unsecured obligations of our company. The 5.000% Senior Notes Indenture contains certain affirmative and negative covenants, including limitations on restricted payments (such as share repurchases, dividends, and early payment of indebtedness), limitations on indebtedness, limitations on the sale of assets, and limitations on liens. Payments that would otherwise be characterized as restricted payments are permitted under the 5.000% Senior Notes Indenture in an amount not to exceed 50% of our consolidated net income for the period from the issue date to the date of the restricted payment, provided that at the time of making such payments, (a) no default has occurred or would result from the making of such payments, and (b) we are able to satisfy the debt incurrence test under the 5.000% Senior Notes Indenture, or the 5.000% Senior Notes Lifetime Aggregate Limit. In addition, the 5.000% Senior Notes Indenture provides for other exceptions to the restricted payments covenant, each of which are independent of the 5.000% Senior Notes Lifetime Aggregate Limit. Among such exceptions is (i) the ability to make share repurchases each fiscal year in an amount not to exceed the lesser of (A) $50.0 million in any fiscal year or (B) 75.0% of our consolidated net income for the previous four consecutive published fiscal quarters prior to the date of the determination of such consolidated net income, and (ii) share repurchases over the life of the 5.000% Senior Notes in an aggregate amount not to exceed $75.0 million.
	The limitation on indebtedness in the Senior Notes Indentures is only applicable at such time that the consolidated coverage ratio (as set forth in the Senior Notes Indentures) for us and our restricted subsidiaries is less than 3.00 to 1.00. In general, as set forth in the Senior Notes Indentures, the consolidated coverage ratio is determined by comparing our prior four quarters’ consolidated EBITDA (earnings before interest, taxes, depreciation, and amortization) to our consolidated interest expense.
	The credit agreement for our revolving credit facility contains financial covenants relating to maintaining maximum leverage and minimum debt service coverage. The Senior Notes Indentures contain a financial covenant relating to times interest earned.
	Letters of Credit – At October 31, 2014, we had outstanding letters of credit under our credit facility aggregating $1.1 million.

	During fiscal 2014, our board of directors authorized the repurchase of up to $30.0 million of our common stock, subject to certain conditions, in the open market or privately negotiated transactions, commencing no earlier than May 1, 2014. During the six months ended October 31, 2014, we completed this stock repurchase program by repurchasing 2.1 million shares of our common stock for $30.0 million, utilizing cash on hand.
	Earnings per Share
	The following table provides a reconciliation of the income/(loss) amounts and weighted average number of common and common equivalent shares used to determine basic and diluted earnings per share for the three and six months ended October 31, 2014 and 2013 (in thousands, except per share data):

	For the three months ended October 31, 2014, there were 107,081 shares of common stock issuable upon the exercise of stock options and under our 2011 Employee Stock Purchase Plan, or ESPP, that were excluded from the computation of diluted earnings per share because the effect would be antidilutive. For the three months ended October 31, 2013, 88,839 shares of common stock issuable upon the exercise of stock options were excluded from the computation of diluted earnings per share because the effect would be antidilutive.
	For the six months ended October 31, 2014, there were 54,037 shares of common stock issuable upon the exercise of stock options and under our ESPP that were excluded from the computation of diluted earnings per share because the effect would be antidilutive. For the six months ended October 31, 2013, 124,930 shares of common stock issuable upon the exercise of stock options were excluded from the computation of diluted earnings per share because the effect would be antidilutive.
	Incentive Stock and Employee Stock Purchase Plans
	We have two Stock Plans: the 2004 Incentive Stock Plan and the 2013 Incentive Stock Plan. New grants under the 2004 Incentive Stock Plan have not been made since the approval of the 2013 Incentive Stock Plan at our September 23, 2013 annual meeting of stockholders. All new grants covering all participants are issued under the 2013 Incentive Stock Plan. Except in specific circumstances, grants vest over a period of three years and are exercisable for a period of 10 years. The plan also permits the grant of awards to non-employees, which our board of directors has authorized in the past.
	The number of shares and weighted average exercise prices of options for the six months ended October 31, 2014 and 2013 are as follows:
		For the Six Months Ended October 31,
		2014						2013
					Weighted-						Weighted-
					Average						Average
		Shares			Exercise Price			Shares			Exercise Price
	Options outstanding, beginning of year		2,258,349		$	6.15			3,019,127		$	5.31
	Exercised during the period		(166,886	)		4.77			(418,466	)		2.55
	Canceled/forfeited during period		(13,000	)		7.98			(28,000	)		5.59
	Options outstanding, end of period		2,078,463		$	6.25			2,572,661		$	5.76
	Weighted average remaining contractual life	5.49 years						6.22 years
	Options exercisable, end of period		1,986,465		$	6.18			2,013,974		$	5.79
	Weighted average remaining contractual life	5.40 years						5.73 years
	The aggregate intrinsic value of outstanding options as of October 31, 2014 and 2013 was $9.3 million and $14.0 million, respectively. The aggregate intrinsic value of outstanding options that were exercisable as of October 31, 2014 and 2013 was $9.1 million and $11.1 million, respectively. The aggregate intrinsic value of the options exercised for the six months ended October 31, 2014 and 2013 was $1.3 million and $3.9 million, respectively. At October 31, 2014, the total of unrecognized compensation cost of outstanding options was $81,000, which is expected to be recognized over the remaining weighted average vesting period of 0.43 years.
	On September 26, 2011, our stockholders approved our ESPP. All options and rights to participate in our ESPP are nontransferable and subject to forfeiture in accordance with our ESPP guidelines. In the event of certain corporate transactions, each option outstanding under our ESPP will be assumed or an equivalent option will be substituted by the successor corporation or a parent or subsidiary of such successor corporation. During the six months ended October 31, 2014 and 2013, 79,291 and 84,081 shares were purchased under our ESPP, respectively.
	The following assumptions were used in valuing our ESPP purchases during the six-month periods ended October 31, 2014 and 2013:
		For the Six Months Ended October 31,
		2014		2013
	Risk-free interest rate	0.04%		0.04%
	Expected term	6 months		6 months
	Expected volatility	36.00%		35.20%
	Dividend yield	0%		0%
	We measure the cost of employee services received in exchange for an award of an equity instrument based on the grant-date fair value of the award. We calculate the fair value of our stock options issued to employees using the Black-Scholes model at the time the options were granted. That amount is then amortized over the vesting period of the option. With our ESPP, fair value is determined at the beginning of the purchase period and amortized over the term of each exercise period.
	We estimate expected volatility using historical volatility for the expected term. The fair value of each stock option or ESPP purchase was estimated on the date of the grant using the Black-Scholes option pricing model (using the risk-free interest rate, expected term, expected volatility, and dividend yield variables). The total stock-based compensation expense, including stock options, purchases under our ESPP, restricted stock units, or RSUs, and performance-based RSUs, or PSUs, was $2.8 million and $4.8 million for the six months ended October 31, 2014 and 2013, respectively. Stock-based compensation expense is included in cost of sales, sales and marketing, research and development, and general and administrative expenses.
	We grant service-based RSUs to employees, consultants, and directors. The awards are made at no cost to the recipient. An RSU represents the right to acquire one share of our common stock but does not carry voting or dividend rights. Except in specific circumstances, RSU grants to employees generally vest over a period of three years with one-third of the units vesting on each anniversary date of the grant date. The aggregate fair value of our RSU grants is being amortized to compensation expense over the vesting period.
	We grant PSUs with market conditions to our executive officers. At the time of grant, we calculate the fair value of our market condition PSUs using the Monte-Carlo simulation (using the risk-free interest rate, expected volatility, the correlation coefficient utilizing the same historical price data used to develop the volatility assumptions and dividend yield variables).
	The market-condition PSUs vest, and the fair value of such PSUs will be recognized, over the corresponding three-year performance period. Our market-condition PSUs have a maximum aggregate award equal to 200% of the target amount granted. The number of market-condition PSUs that may be earned depends upon the total stockholder return, or TSR, of our common stock compared with the TSR of the Russell 2000 Index, or the RUT, or the NASDAQ Composite Index, or the IXIC, as applicable, over the three-year performance period. Our stock must outperform the RUT or the IXIC, as applicable, by 10% in order for the target award to be earned.
	During the six months ended October 31, 2014, we granted 237,100 service-based RSUs, including 20,000 RSUs to a newly appointed executive officer in connection with his hiring; 50,500 RSUs to our directors; and 166,600 RSUs to non-executive officer employees. In addition, in connection with a 2011 grant, we vested 46,600 market-condition PSUs (i.e., the target amount granted), which achieved the maximum aggregate award possible resulting in awards totaling 93,200 shares to certain of our executive officers and a former executive officer. Compensation expense recognized related to grants of RSUs and PSUs was $2.4 million for the six months ended October 31, 2014. We delivered common stock to employees and directors during the six months ended October 31, 2014 under vested RSUs and PSUs with a total market value of $3.6 million.
	During the six months ended October 31, 2013, we granted 450,656 service-based RSUs, including 250,000 RSUs to certain of our executive officers; 42,238 to our directors; and 153,418 RSUs to non-executive officer employees. In addition, in connection with a 2010 grant, we vested 30,000 market-condition PSUs (i.e., the target amount granted), which achieved the maximum aggregate award possible resulting in awards totaling 60,000 shares to an executive officer and former executive officer. Compensation expense recognized related to grants of RSUs and PSUs was $3.7 million for the six months ended October 31, 2013. We delivered common stock to employees and directors during the six months ended October 31, 2013 under vested RSUs and PSUs with a total market value of $2.4 million.
	A summary of activity in unvested RSUs and PSUs for the six months ended October 31, 2014 and 2013 is as follows:
		For the Six Months Ended October 31,
		2014						2013
		Total # of			Weighted Average			Total # of			Weighted Average
		Restricted			Grant Date			Restricted			Grant Date
		Stock Units			Fair Value			Stock Units			Fair Value
RSUs and PSUs outstanding, beginning of year		1,015,475		$	10.56			781,586		$	8.42
Awarded		283,700			11.18			480,656			10.3
Vested		(312,670	)		8.71			(210,230	)		8.18
Forfeited		(69,371	)		12.11			(12,518	)		8.61
RSUs and PSUs outstanding, end of period		917,134		$	12.25			1,039,494		$	9.23
As of October 31, 2014, there was $5.6 million of unrecognized compensation cost related to unvested RSUs and PSUs. This cost is expected to be recognized over a weighted average remaining contractual term of 1.4 years.

Commitments And Contingencies Disclosure [Abstract]	'
Commitments and Contingencies	'
	(7) Commitments and Contingencies:
	Litigation
	On January 19, 2010, the U.S. Department of Justice, or DOJ, unsealed indictments of 22 individuals from the law enforcement and military equipment industries, one of whom was our former Vice President-Sales, International & U.S. Law Enforcement. We were not charged in the indictment. We also were served with a Grand Jury subpoena for the production of documents. The DOJ then conducted an investigation to determine whether we had violated the Foreign Corrupt Practices Act, or FCPA. We have cooperated fully with the DOJ in this matter. On February 21, 2012, the DOJ filed a motion to dismiss with prejudice the indictments of the remaining defendants who were pending trial, including our former Vice President-Sales, International & U.S. Law Enforcement. On February 24, 2012, the district court granted the motion to dismiss.
	Following extensive investigation and evaluation, the DOJ declined to pursue any FCPA charges against us and closed its investigation. The DOJ noted our “thorough cooperation” in correspondence to us.
	In fiscal 2011, we received a subpoena from the staff of the SEC giving notice that the SEC was conducting a non-public, fact-finding inquiry to determine whether there had been any violations of the federal securities laws. It appears this civil inquiry was triggered in part by the DOJ investigation into potential FCPA violations. We undertook a comprehensive review of company policies and procedures. Effective July 28, 2014, we settled civil charges filed by the SEC in an administrative proceeding relating to the anti-bribery, internal controls, and books and records provisions of the FCPA. Under the terms of the settlement, in which we neither admitted nor denied the allegations made by the SEC, the SEC noted our cooperation with the inquiry. We consented to pay $2.0 million, and we agreed to undertake certain reporting obligations to the SEC concerning our FCPA compliance for two years following the settlement date.
	We are involved in a purported stockholder derivative lawsuit. This action was brought by a derivative plaintiff on behalf of our company against certain of our officers, directors, and employees. The lawsuit is based principally on a theory of breach of fiduciary duties arising from a 2007 class action lawsuit that has since been dismissed with prejudice. The derivative plaintiff seeks damages on behalf of our company from the individual defendants. Damages sought include equitable and/or injunctive relief, actions to improve corporate governance, and recovery of attorneys’ fees. The action was dismissed by the court in 2013, but is currently under review on appeal by the derivative plaintiff. A decision on the appeal is not expected until 2015.
	We are a defendant in nine product liability cases and are aware of approximately 10 other product liability claims, primarily alleging defective product design, defective manufacturing, or failure to provide adequate warnings. In addition, we are a co-defendant in a case filed on August 27, 1999 by the city of Gary, Indiana against numerous firearm manufacturers, distributors, and dealers seeking to recover damages allegedly arising out of the misuse of firearms by third parties. We believe that the various allegations as described above are unfounded, and, in addition, that any accident and any results from them were due to negligence or misuse of the firearm by the claimant or a third party.
	In addition, we are involved in lawsuits, claims, investigations, and proceedings, including commercial, environmental, and employment matters, which arise in the ordinary course of business.
	The relief sought in individual cases primarily includes compensatory and, sometimes, punitive damages. Certain of the cases and claims seek unspecified compensatory or punitive damages. In others, compensatory damages sought may range from less than $75,000 to approximately $1.5 million. In our experience, initial demands do not generally bear a reasonable relationship to the facts and circumstances of a particular matter.
	We are vigorously defending ourselves in the lawsuits to which we are subject. An unfavorable outcome or prolonged litigation could harm our business. Litigation of this nature also is expensive and time consuming and diverts the time and attention of our management.
	We monitor the status of known claims and the related product liability accrual, which includes amounts for defense costs for asserted and unasserted claims. After consultation with litigation counsel and the review of the merits of each claim, we have concluded that we are unable to reasonably estimate the probability or the estimated range of reasonably possible losses related to material adverse judgments related to such claims and, therefore have not accrued for any such judgments. In the future, should we determine that a loss (or an additional loss in excess of our accrual) is at least reasonably possible and material, we would then disclose an estimate of the possible loss or range of loss, if such estimate could be made, or disclose that an estimate could not be made. We believe that we have provided for adequate reserves for defense costs.
	We have recorded our liability for defense costs before consideration for reimbursement from insurance carriers. We have also recorded the amount due as reimbursement under existing policies from the insurance carriers as a receivable in other current assets and other assets.
	Environmental Remediation
	We are subject to numerous federal, state, and local laws that regulate both the health and safety of our workforce as well as our environmental liability, including those regulations monitored by the Occupational Health and Safety Administration (OSHA), the National Fire Protection Association (NFPA), and the Department of Public Health (DPH). Though not exhaustive, examples of applicable regulations include confined space safety, walking and working surfaces, machine guarding, and life safety.
	We are required to comply with regulations that mitigate any release into the environment. These laws have required, and are expected to continue to require, us to make significant expenditures of both a capital and expense nature. Several of the more significant federal laws applicable to our operations include the Clean Air Act, the Clean Water Act, the Comprehensive Environmental Response, Compensation and Liability Act, or CERCLA, and the Solid Waste Disposal Act, as amended by the Resource Conservation and Recovery Act.
	We have in place programs and personnel to monitor compliance with various federal, state, and local environmental regulations. In the normal course of our manufacturing operations, we are subject to governmental proceedings and orders pertaining to waste disposal, air emissions, and water discharges into the environment. We fund our environmental costs through cash flows from operations.
	We are required to remediate hazardous waste at our facilities. Currently, we own designated sites in Springfield, Massachusetts and are subject to two release areas, which are the focus of remediation projects as part of the Massachusetts Contingency Plan, or the MCP. The MCP provides a structured environment for the voluntary remediation of regulated releases. We may be required to remove hazardous waste or remediate the alleged effects of hazardous substances on the environment associated with past disposal practices at sites not owned by us. We have received notice that we are a potentially responsible party from the Environmental Protection Agency and/or individual states under CERCLA or a state equivalent at two sites.
	As of October 31, 2014 and April 30, 2014, we had recorded a $623,000 environmental reserve in non-current liabilities, which represents the net present value of the estimated obligation. Our estimate of these costs is based upon currently enacted laws and regulations, currently available facts, experience in remediation efforts, existing technology, and the ability of other potentially responsible parties or contractually liable parties to pay the allocated portions of any environmental obligations.
	When the available information is sufficient to estimate the amount of liability, that estimate has been used. When the information is only sufficient to establish a range of probable liability and no point within the range is more likely than any other, the lower end of the range has been used. We may not have insurance coverage for our environmental remediation costs. We have not recognized any gains from probable recoveries or other gain contingencies. The environmental reserve was calculated using undiscounted amounts based on independent environmental remediation reports obtained.
	Under the asset purchase agreement with TTPP, the former stockholder of TTPP has indemnified us for losses arising from, among other things, environmental conditions related to its manufacturing activities. Of the purchase price, $3.0 million has been placed in an escrow account, a portion of which will be applied to environmental remediation at the manufacturing site in Deep River, Connecticut. It is not presently possible to estimate the ultimate amount of all remediation costs and potential uses of the escrow. We believe the likelihood of environmental remediation costs exceeding the amount available in escrow to be remote.
	Based on information known to us, we do not expect current environmental regulations or environmental proceedings and claims to have a material adverse effect on our consolidated financial position, results of operations, or cash flows. However, it is not possible to predict with certainty the impact on us of future environmental compliance requirements or of the cost of resolution of future environmental proceedings and claims, in part because the scope of the remedies that may be required is not certain, liability under federal environmental laws is joint and several in nature, and environmental laws and regulations are subject to modification and changes in interpretation. There can be no assurance that additional or changing environmental regulation will not become more burdensome in the future and that any such development would not have a material adverse effect on our company.

	Interim Financial Information - The consolidated balance sheet as of October 31, 2014, the consolidated statements of income for the three and six months ended October 31, 2014 and 2013, the consolidated statement of changes in stockholders’ equity for the six months ended October 31, 2014, and the consolidated statements of cash flows for the six months ended October 31, 2014 and 2013 have been prepared by us and are unaudited. In our opinion, all adjustments, which include only normal recurring adjustments necessary to fairly present the financial position, results of operations, changes in stockholders’ equity, and cash flows at October 31, 2014 and for the periods presented, have been included. All significant intercompany transactions have been eliminated in consolidation. The consolidated balance sheet as of April 30, 2014 has been derived from our audited consolidated financial statements.
	Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended April 30, 2014, filed with the SEC on June 19, 2014. The results of operations for the six months ended October 31, 2014 may not be indicative of the results that may be expected for the year ending April 30, 2015, or any other period.
Discontinued Operations	'
	Discontinued Operations - SWSS LLC, formerly Smith & Wesson Security Solutions, Inc., or SWSS, our former security solutions division, is presented as discontinued operations in the consolidated statements of income for all periods presented. Unless stated otherwise, any reference to the consolidated statements of income items in the notes to the consolidated financial statements refers to results from continuing operations.
Recently Issued Accounting Standards	'
	Recently Issued Accounting Standards – In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606), or ASU 2014-09. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for interim reporting periods beginning October 1, 2017. Early adoption is not permitted. We are currently evaluating the impact, if any, that ASU 2014-09 will have on our consolidated financial statements
