Organization Consolidation And Presentation Of Financial Statements [Abstract]
Revenue Recognition	Revenue Recognition Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, "Revenue from Contracts with Customers," also known as the "New Revenue Standard" (“ASU 2014-09”), on a modified retrospective basis, with no cumulative effect of adoption to any of the financial statement line items. The Company’s revised policy is as follows: The Company recognizes revenue from the sale of its products in accordance with the criteria in Accounting Standards Codification (“ASC”) 606, Revenue From Contracts with Customers, which are: Step 1: Identify the contract(s) with a customer. Step 2: Identify the performance obligations in the contract. Step 3: Determine the transaction price. Step 4: Allocate the transaction price to the performance obligations in the contract. Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation. The Company meets these conditions upon the Company’s satisfaction of the performance obligation, usually at the time of shipment to the customer, because control passes to the customer at that time. Our standard terms for customers are net due within 30 days, with a few exceptions, none regularly exceeding 60 days. The Company provides disaggregated revenue details by segment in Note K – Segment Information, and geographic markets in Note L – Domestic and Foreign Revenues. The Company offers a limited right of return and/or authorized price protection provisions in its agreements with certain electronic component distributors who resell the Company's products to original equipment manufacturers or electronic manufacturing services companies. As a result, the Company estimates and records a reserve for future returns and other charges against revenue at the time of shipment consistent with the terms of sale. The reserve is estimated based on historical experience with each respective distributor. These reserves and charges are immaterial as the Company does not have a history of significant price protection adjustments or returns. The Company provides a standard assurance warranty that does not create a performance obligation. The Company applies the practical expedient for shipping and handling as fulfillment costs. Recent Accounting Pronouncements In March 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-05, “Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118,” to provide guidance for companies that may not have completed their accounting for the income tax effects of the Tax Cut and Jobs Act (“Tax Act”) in the period of enactment, which is the period that includes December 22, 2017. ASU 2018-05 provides for a provisional one year measurement period for entities to finalize their accounting for certain income tax effects related to the Tax Act. ASU 2018-05 requires disclosure of the reasons for incomplete accounting, additional information or analysis needed, among other relevant information. The Company expects to finalize its provisional amounts by the fourth quarter of fiscal 2018. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. The objective of this update is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods and is to be applied utilizing a modified retrospective approach. The Company does not expect this standard to have a material impact on its consolidated financial statements because there are no material operating leases. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825)”. ASU 2016-01 revises the classification and measurement of investments in certain equity investments and the presentation of certain fair value changes for certain financial liabilities measured at fair value. ASU No. 2016-01 requires the change in fair value of many equity investments to be recognized in net income. ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The Company adopted this guidance effective January 1, 2018 and made a cumulative effect adjustment to the Company's retained earnings of $35,000. In May 2014, the FASB issued ASU 2014-09. This update is the result of a collaborative effort by the FASB and the International Accounting Standards Board to simplify revenue recognition guidance, remove inconsistencies in the application of revenue recognition, and to improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. The core principle of the guidance 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 receive for those goods or services. ASU 2014-09 became effective for us on January 1, 2018 and was applied on a modified retrospective basis, with no cumulative effect of adoption to any of the financial statement line items.
