Interim Financial Information	Interim Financial Information – The condensed consolidated balance sheet as of July 31, 2018, the condensed consolidated statements of income and comprehensive income for the three months ended July 31, 2018 and 2017, the condensed consolidated statement of changes in stockholders’ equity for the three months ended July 31, 2018, and the condensed consolidated statements of cash flows for the three months ended July 31, 2018 and 2017 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, 2018 and for the periods presented, have been included. All intercompany transactions have been eliminated in consolidation. The consolidated balance sheet as of April 30, 2018 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, 2018. The results of operations for the three months ended July 31, 2018 may not be indicative of the results that may be expected for the year ending April 30, 2019, or any other period.
Revenue Recognition	Revenue Recognition - We recognize revenue in accordance with the provisions of Accounting Standard Update, Revenue from Contracts with Customers (Topic 606), which became effective for us on May 1, 2018. Generally all performance obligations are satisfied and revenue is recognized when the risks and rewards of ownership have transferred to the customer, which is generally upon shipment but could be delayed until the receipt of customer acceptance. In some instances, sales include multiple performance obligations. The most common of these instances relates to sales promotion programs under which customers are entitled to receive free goods based upon their purchase of our products. The fulfillment of these free goods are our responsibility. In such instances, we allocate the revenue of the promotional sales based on the estimated level of participation in the sales promotional program and the timing of the shipment of all of the products included in the promotional program, including the free goods. Revenue is recognized proportionally as each performance obligation is satisfied, based on the relative transaction price of each product. The net change in contract liabilities for a given period is reported as an increase or decrease to sales. Our product sales are generally sold free on board, or FOB, shipping point and provide payment terms to most commercial customers ranging from 20 to 90 days of product shipment with a discount available to some customers for early payment. For contracts with discounted terms, the transaction price is determined upon establishment of the contract that contains the final terms of the sale, including the description, quantity, and price of each product purchased. We estimate variable consideration relative to the amount of cash discounts to which customers are likely to be entitled. In some instances, we provide longer payment terms, particularly as it relates to our hunting dating programs, which represent payment terms due in the fall for certain orders of hunting products received in the spring and summer. We do not consider these extended terms to be a significant financing component of the contract because the payment terms are less than one year. In all cases, we consider our costs related to shipping and handling to be a cost of fulfilling the contract with the customer.
Recently Issued Accounting Standards	Recently Issued Accounting Standards – In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, 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. We adopted the new standard on May 1, 2018 utilizing the modified retrospective approach. See Note 3 – Revenue Recognition and Contracts with Customers below for more information. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), or ASU 2016-02, which amends the existing guidance to require lessees to recognize lease assets and lease liabilities arising from operating leases in a classified balance sheet. The requirements of this ASU are effective for financial statements for annual periods beginning after December 15, 2018, and early adoption is permitted. We are in the process of implementing leasing software to assist us in the accounting and tracking of leases. Although we anticipate the effect of ASU 2016-02 will result in increasing our lease assets and lease liabilities on our condensed consolidated balance sheet, we are still evaluating the impact that it will have on our condensed consolidated financial statements. We plan to adopt ASU 2016-02 in our first quarter of fiscal 2020.
