Basis of Presentation	(2) Basis of Presentation: Interim Financial Information – The condensed consolidated balance sheet as of July 31, 2017, the condensed consolidated statements of (loss)/income and comprehensive (loss)/income for the three months ended July 31, 2017 and 2016, the condensed consolidated statement of changes in stockholders’ equity for the three months ended July 31, 2017, and the condensed consolidated statements of cash flows for the three months ended July 31, 2017 and 2016 have been prepared by us without audit. 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 July 31, 2017 and for the periods presented, have been included. All intercompany transactions have been eliminated in consolidation. The consolidated balance sheet as of April 30, 2017 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, or GAAP, have been condensed or omitted. These condensed 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, 2017. The results of operations for the three months ended Recently Issued Accounting Standards – In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2014-09, (Topic 606), or ASU 2014-09. The core principle of ASU No. 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 No. 2014-09 is effective for interim reporting periods beginning December 15, 2017, and early adoption is permitted. In March 2016, the FASB issued ASU No. 2016-08, , which clarifies the guidance relating to principal versus agent considerations. Additionally, in April 2016, the FASB issued ASU No. 2016-10, , which clarifies the identification of performance obligations and licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, (Topic 606), which provides clarifying guidance in certain narrow areas and adds some practical expedients. The effective dates for these ASUs is the same as the effective date for ASU No. 2014-09. We have engaged third party specialists to assist us in evaluating the impact these ASUs will have on our consolidated financial statements, which we currently do not expect to be material. In July 2015, the FASB issued ASU 2015-11, Inventory - Simplifying the Measurement of Inventory In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), In March 2016, the FASB issued ASU No. 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting

Business Combinations [Abstract]
Acquisitions	(3) Acquisitions: In fiscal 2017, we acquired substantially all of the net assets of Taylor Brands, LLC and Ultimate Survival Technologies Inc., as well as all of the issued and outstanding stock of Crimson Trace Corporation for an aggregate purchase price of $211.1 million, net of cash acquired, subject to certain adjustments, utilizing cash on hand. In connection with the purchase of Ultimate Survival Technologies, Inc., up to an additional $2.0 million may be paid over a period of two years, contingent upon the financial performance of the acquired business. The valuation of this contingent consideration liability was established in accordance with ASC 805 — Business Combinations We are in the process of finalizing the valuations of the assets acquired and liabilities assumed related to the 2017 Acquisitions. Therefore, the fair values for these acquisitions are subject to further adjustments as we obtain additional information during the respective measurement periods, which will not exceed 12 months from the date of each acquisition. The 2017 Acquisitions will necessitate the use of this measurement period to adequately analyze and assess a number of factors used in establishing the asset and liability fair values as of each acquisition date, including the significant contractual and operational factors underlying the trade name, developed technology, and customer relationship intangible assets and the related tax impacts of any changes made. During the three months ended July 31, 2017, we increased goodwill by $83,000, primarily as a result of accounts receivable and payroll adjustments relating to the 2017 Acquisitions. The following table summarizes the estimated preliminary allocation of the purchase price for the 2017 Acquisitions (in thousands): 2017 Acquisitions Measurement (As Initially Period 2017 Acquisitions Reported) Adjustments (As Adjusted) Accounts receivable $ 11,635 $ (172 ) $ 11,463 Inventories 31,269 453 31,722 Income tax receivable — 68 68 Other current assets 430 (132 ) 298 Property, plant, and equipment 8,232 — 8,232 Intangibles 97,850 — 97,850 Goodwill 92,801 (58 ) 92,743 Total assets acquired 242,217 159 242,376 Accounts payable 6,214 18 6,232 Accrued expenses 973 158 1,131 Accrued payroll 1,500 (72 ) 1428 Accrued income taxes 6 (6 ) — Accrued warranty 98 96 194 Deferred income taxes 20,658 (35 ) 20,623 Total liabilities assumed 29,449 159 29,608 $ 212,768 $ — $ 212,768 Included in general and administrative costs are $1.3 million of acquisition-related costs incurred during the three months ended July 31, 2016 for the 2017 Acquisitions. The 2017 Acquisitions generated $15.5 million of revenue for the three months ended July 31, 2017. We amortize intangible assets in proportion to expected yearly revenue generated from the intangibles that we acquire. We amortize order backlog over the estimated life during which the backlog is fulfilled. The following are the identifiable intangible assets acquired (in thousands) in the 2017 Acquisitions and their respective weighted average lives: Weighted Average Amount Life (In years) Developed technology $ 3,000 4.1 Customer relationships 76,600 5.1 Trade names 17,000 4.8 Order backlog 1,150 0.3 Non-competition agreement 100 3.4 $ 97,850 Additionally, the following table reflects the unaudited pro forma results of operations assuming that the 2017 Acquisitions had occurred on May 1, 2015 (in thousands, except per share data): For the Three Months Ended July 31, 2016 Net sales $ 229,092 Income from operations 51,109 Net income per share - diluted 0.63 The unaudited pro forma income from operations for the three months ended July 31, 2016 has been adjusted to reflect increased cost of goods sold from the fair value step-up in inventory, which is expensed over the first inventory cycle, and the amortization of intangibles and order backlog recorded as if the 2017 Acquisitions had occurred on May 1, 2015. The unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of the actual results that would have been achieved had the 2017 Acquisitions occurred as of May 1, 2015 or the results that may be achieved in future periods.

Notes and Loans Payable	3 Months Ended

Debt Disclosure [Abstract]
Notes and Loans Payable	(5) Notes and Loans Payable: Credit Facilities – On June 15, 2015, we and certain of our domestic subsidiaries entered into an unsecured credit facility, or the Credit Agreement, with TD Bank, N.A. and other lenders, or the Lenders, which included a $175.0 million revolving line of credit, or the Revolving Line and a $105.0 million term loan, or the Term Loan, of which $92.4 million was outstanding as of July 31, 2017. The Revolving Line provides for availability until October 27, 2021 for general corporate purposes, with borrowings to bear interest at a variable rate equal to LIBOR or prime plus an applicable margin based on our consolidated leverage ratio, at our election. On October 27, 2016, we entered into a second amendment to the Credit Agreement, or the Second Amendment, with the Lenders. Among other things, the Second Amendment increased the Revolving Line, available from the Lenders to $350.0 million, increased the option to expand the credit commitment to an additional $150.0 million, and extended the maturity of the Revolving Line from June 15, 2020 to October 27, 2021. Other than the changes described in the Second Amendment, we otherwise remain subject to the terms of the Credit Agreement, as described below. We incurred $525,000 of debt issuance costs related to this amendment and have recorded these costs in notes and loans payable in the condensed consolidated balance sheet. As of July 31, 2017, we had $75.0 million of borrowings outstanding on the Revolving Line, which bore interest at 2.73%, equal to the LIBOR rate plus an applicable margin. The Term Loan, which bears interest at a variable rate, requires principal payments of $6.3 million per annum plus interest, payable quarterly. Any remaining outstanding amount on the maturity date of June 15, 2020 for the Term Loan will be due in full. We incurred $1.0 million of debt issuance costs related to the Credit Agreement, which are included in notes and loans payable in the accompanying condensed consolidated balance sheet. We were required to obtain fixed interest rate protection on the Term Loan covering not less than 75% of the aggregate outstanding principal balance of the Term Loan. Accordingly, on June 18, 2015, we entered into an interest rate swap agreement, which expires on June 15, 2020, that covered 100% of the $105.0 million of floating rate debt. On July 6, 2015, we executed an interest rate swap pursuant to such agreement, which requires us to pay interest at a defined rate of 1.56% while receiving interest at a defined variable rate of one-month LIBOR (0.188%). This swap, when combined with the applicable margin based on our consolidated leverage ratio, effectively fixed our interest rate on the Term Loan, which is subject to change based on changes in our consolidated leverage ratio. As of July 31, 2017, our interest rate on the Term Loan was 3.06%. As of July 31, 2017, the interest rate swap was considered effective and had no effect on earnings. The fair value of the interest rate swap on July 31, 2017 was an asset of $453,000 and was included in other assets on our condensed consolidated balance sheet. We do not expect the interest rate swap to have any material effect on earnings within the next 12 months. 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 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. On and after July 15, 2017, 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 a redemption price of 100% of the principal amount of the 5.000% Senior Notes to be redeemed plus accrued and unpaid interest 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 are (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 5.000% Senior Notes Indenture is only applicable at such time that the consolidated coverage ratio (as set forth in the 5.000% Senior Notes Indenture) for us and our restricted subsidiaries is less than 3.00 to 1.00. In general, as set forth in the 5.000% Senior Notes Indenture, 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 credit facility contains financial covenants relating to maintaining maximum leverage and minimum debt service coverage. The 5.000% Senior Notes Indenture contains a financial covenant relating to times interest earned. Letters of Credit – At July 31, 2017, we had outstanding letters of credit under our credit facility aggregating $1.1 million.

Our cash and cash equivalents, which are measured at fair value on a recurring basis, totaled $43.4 million and $61.5 million as of July 31, 2017 and April 30, 2017, respectively. We utilized Level 1 of the value hierarchy to determine the fair values of these assets. Level 2 — Financial assets and liabilities whose values are based on quoted prices in markets in which trading occurs infrequently or whose values are based on quoted prices of instruments with similar attributes in active markets. Level 2 inputs include the following: • quoted prices for identical or similar assets or liabilities in non-active markets (such as corporate and municipal bonds that trade infrequently); • inputs other than quoted prices that are observable for substantially the full term of the asset or liability (such as interest rate and currency swaps); and • inputs that are derived principally from or corroborated by observable market data for substantially the full term of the asset or liability (such as certain securities and derivatives). The carrying value of our Term Loan approximated the fair value as of July 31, 2017, in considering Level 2 inputs within the hierarchy. The fair value of our 5.000% Senior Notes as of July 31, 2017 approximated the carrying value in considering Level 2 inputs within the hierarchy as the Senior Notes are not frequently traded. The fair value of the interest rate swap was estimated by a third party using inputs that are observable or that can be corroborated by observable market data, such as interest rate yield curves, and, therefore, is classified within Level 2 of the valuation hierarchy. For more information regarding the interest rate swap, refer to Note 5 — Notes and Loans Payable Level 3 — Financial assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect our assumptions about the assumptions a market participant would use in pricing the asset or liability. The acquisition-related contingent consideration liability represents the estimated fair value of additional future earn-outs payable for acquisitions of businesses that included earn-out clauses. The valuation of the contingent consideration will be evaluated on an ongoing basis and is based on management estimates and entity-specific assumptions which are considered Level 3 inputs. In connection with the purchase of Ultimate Survival Technologies, Inc., up to an additional $2.0 million may be paid over a period of two years, contingent upon the financial performance of the acquired business. The valuation of this contingent consideration liability was established in accordance with ASC 805 — Business Combinations

The weighted-average periods of amortization by intangible asset class is approximately five years for customer relationships, six years for developed technology, and five years for patents, trademarks, and trade names. Amortization expense, excluding amortization of deferred financing costs, amounted to $5.7 million and $2.7 million for the three months ended July 31, 2017 and 2016, respectively. Estimated amortization expense of intangible assets for the remainder of fiscal 2018 and succeeding fiscal years is as follows: Fiscal Amount 2018 $ 17,208 2019 23,207 2020 20,374 2021 17,559 2022 14,843 Thereafter 41,677 Total $ 134,868 On an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired, we evaluate the fair value of the definite and indefinite-lived intangible assets to determine if an impairment charge is required. We performed our most recent annual impairment review as of February 1, 2017. Other than the reduction in the fair value of the contingent consideration liability mentioned above, there were no events or changes in circumstances that would indicate the fair value of intangible assets was reduced to below its carrying value during the three months ended July 31, 2017, and therefore intangible assets were not tested for impairment.

Equity [Abstract]
Stockholders' Equity	(10) Stockholders’ Equity: Treasury Stock During fiscal 2017, our board of directors authorized the repurchase of up to $50.0 million of our common stock, subject to certain conditions, in the open market or in privately negotiated transactions until March 28, 2019. This share repurchase authorization is similar to the $50.0 million authorization from June 2015 under which we repurchased 2.6 million shares of common stock for $50.0 million in fiscal 2017. As of July 31, 2017, there were no share repurchases under this stock repurchase program. Earnings per Share The following table provides a reconciliation of the net income amounts and weighted average number of common and common equivalent shares used to determine basic and diluted earnings per share for the three months ended July 31, 2017 and 2016 (in thousands, except per share data): For the Three Months Ended July 31, 2017 2016 Net Per Share Net Per Share Income Shares Amount Income Shares Amount Basic earnings $ (2,165 ) 53,905 $ (0.04 ) $ 35,222 56,049 $ 0.63 Effect of dilutive stock awards — — — — 834 (0.01 ) Diluted earnings $ (2,165 ) 53,905 $ (0.04 ) $ 35,222 56,883 $ 0.62 All of our outstanding stock options and restricted stock units, or RSUs, were included in the computation of diluted earnings per share for the three months ended July 31, 2016. 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 or four 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 three months ended July 31, 2017 and 2016 were as follows: For the Three Months Ended July 31, 2017 2016 Weighted Weighted Average Average Shares Exercise Price Shares Exercise Price Options outstanding, beginning of year 335,160 $ 6.58 389,360 $ 6.16 Exercised during the period — — — — Options outstanding, end of period 335,160 $ 6.58 389,360 $ 6.16 Weighted average remaining contractual life 3.76 years 4.79 years Options exercisable, end of period 335,160 $ 6.58 389,360 $ 6.16 Weighted average remaining contractual life 3.76 years 4.79 years The aggregate intrinsic value of outstanding and exercisable stock options as of July 31, 2017 and 2016 was $4.7 million and $9.1 million, respectively. There were no stock options exercised for the three months ended July 31, 2017 and 2016. At July 31, 2017, there were no unrecognized compensation costs of outstanding options. On September 26, 2011, our stockholders approved our Employee Stock Purchase Plan, or ESPP. Under the ESPP, each participant is granted an option to purchase our common stock on each subsequent exercise date during the offering period, (as such terms are defined in the ESPP) in accordance with the terms of the ESPP. The option to purchase shares is exercised automatically unless the participant withdraws from the plan in accordance with the terms of the ESPP or the participant’s employment is terminated. Neither plan contributions credited to a participant’s account nor any rights to exercise any option or receive shares of common stock may be assigned, transferred, pledged, or otherwise disposed of other than by will or the laws of descent and distribution. 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. 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 are 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 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, RSUs, and performance-based RSUs, or PSUs, was $1.9 million and $1.8 million for the three months ended July 31, 2017 and 2016, 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 and does not carry voting or dividend rights. Except in specific circumstances, RSU grants to employees generally vest over a period of three or four years with one-third or one-fourth of the units vesting, respectively, on each anniversary date of the grant date. We amortize the aggregate fair value of our RSU grants to compensation expense over the vesting period. We grant PSUs to our executive officers and our employees who are not executive officers. At the time of grant, we calculate the fair value of our 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 PSUs vest, and the fair value of such PSUs will be recognized, over the corresponding three-year performance period. Our PSUs have a maximum aggregate award potential equal to 200% of the target amount granted. Generally, the number of 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 RUT, over the three-year performance period. For PSUs, our stock must outperform the RUT by 5% in order for the target award to vest. In addition, there is a cap on the number of shares that can be earned under our PSUs, which is equal to six times the grant-date value of each award. In certain circumstances the vested awards will be delivered on the first anniversary of the applicable vesting date. We have applied a discount to the grant date fair value when determining the amount of compensation expense to be recorded for these RSUs and PSUs. During the three months ended July 31, 2017, we granted an aggregate of 164,180 service-based RSUs to non-executive officer employees. In addition, in connection with a 2014 grant, 105,500 PSUs vested (i.e. the target amount granted), which yielded 115.2% of the maximum award possible resulting in awards totaling 121,504 shares to certain of our executive officers. Compensation expense recognized related to grants of RSUs and PSUs was $1.7 million for the three months ended July 31, 2017. We delivered common stock to employees during the three months ended July 31, 2017 under vested RSUs and PSUs with a total market value of $5.5 million. During the three months ended July 31, 2016, we granted an aggregate of 159,321 service-based RSUs, including 129,321 RSUs to non-executive officer employees and 30,000 RSUs to a newly hired executive officer. In addition, in connection with a 2013 grant, 118,500 PSUs vested (i.e. the target amount granted), which yielded 200.0% of the maximum award possible resulting in awards totaling 237,000 shares to certain of our executive officers. Compensation expense recognized related to grants of RSUs and PSUs was $1.6 million for the three months ended July 31, 2016. We delivered common stock to employees during the three months ended July 31, 2016 under vested RSUs and PSUs with a total market value of $10.1 million. A summary of activity in unvested RSUs and PSUs for the three months ended July 31, 2017 and 2016 is as follows: For the Three Months Ended July 31, 2017 2016 Weighted Weighted Total # of Average Total # of Average Restricted Grant Date Restricted Grant Date Stock Units Fair Value Stock Units Fair Value RSUs and PSUs outstanding, beginning of period 1,428,848 $ 18.46 1,215,753 $ 15.38 Awarded 180,184 23.57 277,821 13.81 Vested (247,491 ) 16.94 (360,709 ) 11.50 Forfeited (92,902 ) 12.71 (9,695 ) 14.19 RSUs and PSUs outstanding, end of period 1,268,639 $ 19.91 1,123,170 $ 16.25 As of July 31, 2017, there was $13.1 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 1.9 years.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(11) Commitments and Contingencies: Litigation We are a defendant in three product liability cases and are aware of seven other product liability claims, which primarily allege 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 monetary damages, as well as injunctive relief, 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 $900,000. In our experience, initial demands do not generally bear a reasonable relationship to the facts and circumstances of a particular matter. We believe that our accruals for product liability cases and claims, as described below, are a reasonable quantitative measure of the cost to us of product liability cases and claims. 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 a review of the merit 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, we have not accrued for any such judgments. To the extent that circumstances change and 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 amounts due as reimbursement under existing policies from the insurance carriers as a receivable shown in other current assets and other assets. At this time, an estimated range of reasonably possible additional losses relating to unfavorable outcomes cannot be made.

Recently Issued Accounting Standards	Recently Issued Accounting Standards – In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2014-09, (Topic 606), or ASU 2014-09. The core principle of ASU No. 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 No. 2014-09 is effective for interim reporting periods beginning December 15, 2017, and early adoption is permitted. In March 2016, the FASB issued ASU No. 2016-08, , which clarifies the guidance relating to principal versus agent considerations. Additionally, in April 2016, the FASB issued ASU No. 2016-10, , which clarifies the identification of performance obligations and licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, (Topic 606), which provides clarifying guidance in certain narrow areas and adds some practical expedients. The effective dates for these ASUs is the same as the effective date for ASU No. 2014-09. We have engaged third party specialists to assist us in evaluating the impact these ASUs will have on our consolidated financial statements, which we currently do not expect to be material.
