Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Note R - Recent Accounting Pronouncements Recently Adopted In May 2014, the Financial Accounting Standards Board (the"FASB") issued new accounting guidance ("Topic 606"), Accounting Standards Update No. 2014-09 ("ASU 2014-09"), "Revenue from Contracts with Customers," on revenue recognition. The new standard is an update to Revenue Recognition Topic 605 and provides for a single five-step model to be applied to all revenue contracts with customers as well as requiring additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. Effective January 1, 2018, the Company adopted the requirements of Topic 606 using the cumulative effect adjustment approach. The impacts to the financial statements of this adoption are primarily related to balance sheet classification, including amounts associated with the change in balance sheet classification of the sales returns reserves, with no impact to the income statement as the Company's existing revenue recognition policies are in line with Topic 606. In January 2016, the FASB issued Accounting Standards Update 2016-01 ("ASU 2016-01"), "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 generally requires companies to measure investments in equity securities, except those accounted for under the equity method, at fair value and recognize any changes in fair value in net income. The new guidance must be applied using a modified-retrospective approach and is effective for periods beginning after December 15, 2017 and early adoption is not permitted. The Company adopted the provisions of ASU 2016-01 in the first quarter of 2018 and the adoption did not have a material impact on the Company's financial statements as the Company does not carry investments in equity securities. In August 2016, the FASB issued Accounting Standards Update 2016-15 ("ASU 2016-15"), "Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 clarifies how certain cash receipts and payments should be presented in the statement of cash flows. The main provisions are related to certain types of debt, contingent consideration, insurance proceeds and equity method investee distributions. The guidance is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years with early adoption permitted. The Company adopted the provisions of ASU 2016-15 in the first quarter of 2018. The adoption did not have a material impact on the Company's financial statements as the Company's current financial statements are in line with the provision. In August 2017, the FASB issued Accounting Standards Update 2017-12 ("ASU 2017-12"), "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." ASU 2017-12 changes the recognition and presentation requirements of hedge accounting. The guidance provides new alternatives for applying hedge accounting to additional hedging strategies and measuring the hedged item in fair value hedges of interest rate risk, as well as applies new alternatives for reducing the cost and complexity of applying hedge accounting by easing the requirements for effectiveness testing, hedge documentation and application of the critical terms match method, and reducing the risk of material error correction if a company applies the shortcut method inappropriately. The guidance is effective for annual and interim periods in fiscal years beginning after December 15, 2018 and early adoption is permitted any time after the issuance of ASU 2017-12, including in an interim period. The Company elected to early adopt the new standard in the fourth quarter of 2018 and applied the presentation and disclosure guidance on its forward contracts entered into described in Note L - Derivative Instruments. The adoption of the new standard did not have a material impact on the Company's consolidated financial statements. Not Yet Adopted In August 2018, the FASB issued Accounting Standards Update No. 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software (Topic 350): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract.” This new guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This new guidance is effective for the Company on a prospective or retrospective basis beginning on January 1, 2020, with early adoption permitted. While the Company is currently assessing the impact of the new guidance, it is not expected to have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued Accounting Standards Update No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” This new guidance removes certain disclosure requirements related to the fair value hierarchy, modifies existing disclosure requirements related to measurement uncertainty and adds new disclosure requirements. The new disclosure requirements include disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This new guidance is effective for the Company beginning on January 1, 2020, with early adoption permitted. Certain disclosures in the new guidance will need to be applied on a retrospective basis and others on a prospective basis. While the Company is currently assessing the impact of the new guidance, it is not expected to have a material impact on the Company’s consolidated financial statements. In February 2018, the FASB issued Accounting Standards Update No. 2018-02 ("ASU 2018-02"), "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which allows for stranded tax effects in accumulated other comprehensive income resulting from the U.S. Tax Cuts and Jobs Act to be reclassified to retained earnings. ASU 2018-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact of adopting the new standard and does not expect the new standard to have a material impact on the Company’s financial position or results of operations. In June 2016, the FASB issued Accounting Standards Update 2016-13 ("ASU 2016-13"), "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the effect that the new guidance will have on its financial statements and related disclosures. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 ("ASU 2016-02"), "Leases," as amended, which is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 with early adoption permitted. Under ASU 2016-02, lessees will be required to recognize for all leases with terms longer than twelve months, at the commencement date of the lease, a lease liability, which is a lessee’s obligation to make lease payments arising from a lease measured on a discounted basis, and a right-to-use asset, which is an asset that represents the lessee’s right to use or control the use of a specified asset for the lease term. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition. The Company will adopt the new standard on the effective date January 1, 2019. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. The Company will continue to apply ASC-840, including disclosure requirements, in the comparative periods in the year the Company adopts the new guidance. The new standard provides a number of optional practical expedients. The Company will elect the package of three practical expedients. As such, the Company will not reassess whether expired or existing contracts are or contain a lease and will not need to reassess the lease classifications or reassess the initial direct costs associated with expired or existing leases. The Company will not elect the hindsight practical expedient and the land easement practical expedient, neither of which are applicable to the Company. Also, the Company has elected to take the practical expedient to not separate lease and non-lease components for all asset classes. The Company expects that this standard will have a material effect on our financial statements. While the Company continues to assess all of the effects of adoption, the Company believes the most significant effects relate to: (i) the recognition of new right of use assets and lease liabilities on our balance sheet for primarily real estate operating leases and (ii) providing significant new disclosures about our leasing activities. The Company does not expect a significant change in our leasing activities between now and adoption. Based on our portfolio of leases as of December 31, 2018, approximately $195,000 of lease right-of-use assets and $210,000 of lease right-of use liabilities will be recognized on our balance sheet upon adoption, primarily relating to real estate. We are substantially complete with our implementation efforts.
