Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES  Description of Business  Communications Systems, Inc. (herein collectively called “CSI” or the “Company”) is a Minnesota corporation organized in 1969 that operates primarily as a holding company conducting its business through four business units having operations in the United States, Costa Rica, and the United Kingdom. CSI is principally engaged through its Suttle business unit in the manufacture and sale of connectivity infrastructure products for broadband and voice communications and through its Transition Networks business unit in the manufacture of core media conversion products, Ethernet switches, and other connectivity and data transmission products. Through its JDL Technologies business unit the Company provides technology solutions including virtualization, managed services, wired and wireless network design and implementation, HIPAA-compliant IT services, and converged infrastructure configuration and deployment. Through its Net2Edge business unit, the Company enables telecommunications carriers to connect legacy networks to high-speed services.   The Company classifies its businesses into four segments corresponding to the Suttle, Transition Networks, JDL Technologies and Net2Edge business units. Non-allocated general and administrative expenses are separately accounted for as “Other” in the Company’s segment reporting. Intersegment revenues are eliminated upon consolidation.  Financial Statement Presentation  The condensed consolidated balance sheets and condensed consolidated statement of changes in stockholders’ equity as of June 30, 2017 and the related condensed consolidated statements of loss and comprehensive loss, and the condensed consolidated statements of cash flows for the periods ended June 30, 2017 and 2016 have been prepared by Company management . In the opinion of management, all adjustments (which include only normal recurring adjustments, except where noted) necessary to present fairly the financial position, results of operations, and cash flows at June 30, 2017 and 2016 and for the periods then ended have been made.  Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted. We recommend these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s December 31, 2016 Annual Report to Shareholders on Form 10-K. The results of operations for the period ended June 30, 2017 are not necessarily indicative of operating results for the entire year.  The presentation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenues and expenses during the reporting period. The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates.  Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 , appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference.  Accumulated Other Comprehensive Loss  The components of accumulated other comprehensive loss, net of tax, are as follows:       Foreign Currency Translation Unrealized (loss)/gain on securities Accumulated Other Comprehensive Loss  December 31, 2016 $ (704,000) $ 17,000 $ (687,000)   Net current period change 33,000 (3,000) 30,000   June 30, 2017 $ (671,000) $ 14,000 $ (657,000)  The Company recognized $4,238,000 in foreign currency translation losses within the income statement during the first quarter of 2016 due to the substantial liquidation of our Austin Taylor facility in the U.K. Refer to Note 1 1 for further information regarding the pension liability adjustment recognized in income in the first quarter of 2016.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	NOTE 3 - STOCK-BASED COMPENSATION  Employee Stock Purchase Plan  Under the Company’s Employee Stock Purchase Plan (“ESPP”), employees are able to acquire shares of common stock at 85 % of the price at the end of each current quarterly plan term. The most recent term ended June 30, 2017 . The ESPP is considered compensatory under current Internal Revenue Service rules. At June 30, 2017 , after giving effect to the shares issued as of that date, 65,347 shares remain available for purchase under the ESPP.  2011 Executive Incentive Compensation Plan  On March 28, 2011 the Board adopted and on May 19, 2011 the Company’s shareholders approved the Company’s 2011 Executive Incentive Compensation Plan (“2011 Incentive Plan”). The 2011 Incentive Plan authorizes incentive awards to officers, key employees and non-employee directors in the form of options (incentive and non-qualified), stock appreciation rights, restricted stock, restricted stock units, performance stock units (“deferred stock”), performance cash units, and other awards in stock, cash, or a combination of stock and cash. The 2011 Incentive Plan, as amended, allows the issuance of up to 2,000,000 shares of common stock.  During 2017 , stock options covering 259,686 shares have been awarded to key executive employees and directors. These options expire seven years from the date of award and generally vest 25 % each year beginning one year after the date of award. The Company also granted deferred stock awards of 100,239 shares to key employees during the first quarter of 2017 under the Company’s long-term incentive plan for performance over the 2017 to 2019 period. The actual number of shares of deferred stock, if any, that are ultimately earned by the respective employees will be determined based on achievement against performance goals at the end of the three - year period ending December 31, 2019 and any shares earned will be issued in the first quarter of 2020 to those key employees still with the Company at that time.  At June 30, 2017 , 159,388 shares have been issued under the 2011 Incentive Plan, 1,302,763 shares are subject to currently outstanding options, deferred stock awards, and unvested restricted stock units, and 537,849 shares are eligible for grant under future awards.   Stock Option Plan for Directors  Shares of common stock are reserved for issuance to non-employee directors under options granted by the Company prior to 2011 under its Stock Option Plan for Non-Employee Directors (the “Director Plan”) . Under the Director Plan nonqualified stock options to acquire shares of common stock were automatically granted to each non-employee director concurrent with annual meetings of shareholders in 2010 and earlier years, with t he exercise price of options granted being the fair market value of the common stock on the date of the respective shareholder meetings. Options granted under the Director Plan expire 10 years from date of grant. No options have been granted under the Director Plan since 2011 when the Company amended the Director Plan to prohibit future option grants. As of June 30, 2017 , there were 51,000 shares subject to outstanding options under the Director Plan.  1992 Stock Plan  Under the Company’s 1992 Stock Plan (“the Stock Plan”), shares of common stock may be issued pursuant to stock options, restricted stock or deferred stock grants to officers and key employees. Exercise prices of stock options under the Stock Plan cannot be less than fair market value of the stock on the date of grant. Rules and conditions governing awards of stock options, restricted stock and deferred stock are determined by the Compensation Committee of the Board of Directors, subject to limitations in the Stock Plan . The Company amended the Stock Plan in 2011 to prohibit future equity awards. At June 30, 2017 , after reserving for stock options and deferred stock awards granted in prior years and adjusting for forfeitures and issuances during the year, there were 10,230 shares reserved for issuance under the Stock Plan.

Goodwill And Intangible Assets [Abstract]
Goodwill And Intangible Assets	NOTE 5 –GOODWILL AND INTANGIBLE ASSETS  Goodwill is required to be evaluated for impairment on an annual basis and between annual tests upon the occurrence of certain events or circumstances. In January 2017, the FASB issued new accounting guidance regarding the simplification of the test for goodwill impairment. The new standard eliminates the quantitative goodwill impairment analysis requirement to determine the fair value of individual assets and liabilities of a reporting unit to determine the amount of any goodwill impairment and instead permits an entity to recognize goodwill impairment loss as the excess of a reporting unit's carrying value over the estimated fair value of the reporting unit, to the extent this amount does not exceed the carrying amount of goodwill. The Company chose to adopt this standard early for the annual impairment analysis in 2017. The Company performed the first step of the previous two-step process, which requires that the fair value of the reporting unit be compared to its book value including goodwill. If the fair value is higher than the book value, no impairment is recognized. If the fair value is lower than the book value , an impairment adjustment must be recorded.  The Company performs its annual impairment analysis as of April 1 each year. The Company analyzed the reporting unit that had the goodwill and also analyzed the company as a whole, including the Company’s four separate reporting units. Although JDL Technologies had been profitable for the past eight quarters, the cyclicality and unpredictability of revenues from its education sector raises issues in forecasting cash flows in future quarters used to estimate the reporting unit’s fair value. Based on this analysis of comparing the fair value of each reporting unit to the book value, and comparing the Company’s overall book value with its market capitalization, the Company determined that the book value exceeds the overall fair value of the reporting units as well as the Company’s overall market value. As a result, the Company recorded a goodwill impairment charge totaling $ 1,463,000 during the second quarter of 2017.  The changes in the carrying amount of goodwill for the six months ended June 30, 2017 by segment are as follows:     JDL Technologies   January 1, 2017 $ 1,463,000   Impairment loss (1,463,000)   June 30, 2017 $ -   Gross goodwill 1,463,000  Accumulated impairment loss (1,463,000)  Balance at June 30, 2017 $ -   As part of the overall annual impairment analysis noted above, the Company also reviewed other intangible assets for potential impairment. Based on this analysis, the Company deemed the intangible assets related to customer relationships to be impaired and recorded a $ 154,000 impairment loss during the second quarter of 2017.  The Company’s identifiable intangible assets with finite lives , included in other assets, net on the condensed consolidated balance sheets, are being amortized over their estimated useful lives and were as follows:     June 30, 2017  Gross Carrying Amount Accumulated Amortization Impairment loss Foreign Currency Translation Net   Trademarks $ 93,000 $ (58,000) $ - $ (17,000) $ 18,000  Customer relationships 491,000 (230,000) (154,000) (107,000) -  Technology 229,000 (182,000) - (47,000) -  $ 813,000 $ (470,000) $ (154,000) $ (171,000) $ 18,000      December 31, 2016  Gross Carrying Amount Accumulated Amortization Impairment loss Foreign Currency Translation Net   Trademarks $ 91,000 $ (50,000) $ - $ (20,000) $ 21,000  Customer relationships 491,000 (200,000) - (122,000) 169,000  Technology 229,000 (172,000) - (57,000) -  $ 811,000 $ (422,000) $ - $ (199,000) $ 190,000   Amortization expense on these identifiable intangible assets was $ 24,000 and $ 47,000 for the six months ended 2017 and 2016 , respectively. The amortization expense is included in selling, general and administrative expenses. At June 30, 2017 , the estimated future amortization expense for definite-lived intangible assets for the remainder of 2017 and all of the following four fiscal years is as follows:      Year Ending December 31:  2017 $ 5,000  2018 7,000  2019 2,000  2020 2,000  2021 2,000

Warranty [Abstract]
Warranty	NOTE 6 – WARRANTY  We provide reserves for the estimated cost of product warranties at the time revenue is recognized. We estimate the costs of our warranty obligations based on our warranty policy or applicable contractual warranty, historical experience of known product failure rates, and use of materials and service delivery costs incurred in correcting product failures. Management reviews the estimated warranty liability on a quarterly basis to determine its adequacy. The actual warranty expense could differ from the estimates made by the Company based on product performance. The warranty liability is included in other accrued liabilities on the condensed consolidated balance sheet.  The following table presents the changes in the Company’s warranty liability for the six month periods ended June 30, 2017 and 2016 , respectively, the majority of which relates to a five -year obligation to provide for potential future liabilities for network equipment sales.     2017 2016  Beginning balance $ 600,000 $ 554,000  Amounts charged to expense 25,000 78,000  Actual warranty costs paid (35,000) (58,000)  Ending balance $ 590,000 $ 574,000

Debt [Abstract]
Debt	NOTE 8 – DEBT  Long-term Debt The mortgage on the Company’s headquarters building was payable in monthly installments and carried an interest rate of 6.83% . The mortgage matured on March 1, 2016 and the Company paid $104,000 in the first quarter of 2016 to fully settle the liability.  Line of Credit The Company has a $15,000,000 line of credit from Wells Fargo Bank. The Company had no outstanding borrowings against the line of credit at June 30, 2017 and December 31, 2016 . Due to the revolving nature of loans under our credit facility, additional borrowings and periodic repayments and re-borrowings may be made until the maturity date. The total amount available for borrowings under our credit facility at June 30, 2017 was $ 9,971,000 , based on the borrowing base calculation. Interest on borrowings on the credit line is at LIBOR plus 2.0% ( 3.2% at June 30, 2017 ). The credit agreement expires August 12, 2021 and is secured by assets of the Company. Our credit agreement contains financial covenants including a minimum liquidity balance of $10,000,000 . Liquidity is calculated as the sum of unrestricted cash, marketable securities and the availability on the line of credit. The Company was in compliance with its financial covenants at June 30, 2017 .

Income Taxes [Abstract]
Income Taxes	NOTE 9 – INCOME TAXES In the preparation of the Company’s consolidated financial statements, management calculates income taxes based upon the estimated effective rate applicable to operating results for the full fiscal year. This includes estimating the current tax liability as well as assessing differences resulting from different treatment of items for tax and book accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded on the balance sheet. Management analyzes these assets and liabilities regularly and assesses the likelihood that deferred tax assets will be recovered from future taxable income. At June 30, 2017 there was $ 222,000 of net uncertain tax benefit positions that would reduce the effective income tax rate if recognized. The Company records interest and penalties related to income taxes as income tax expense in the Condensed Consolidated Statements of Loss and Comprehensive Loss .  The Company is subject to U.S. federal income tax as well as income tax of multiple state and foreign jurisdictions. The tax years 2013-2016 remain open to examination by the Internal Revenue Service and the years 2012-2016 remain open to examination by various state tax departments. The tax years from 2013-2016 remain open in Costa Rica. In April 2016, we received notification from the Internal Revenue Service that they would be performing an examination of our 2012 and 2013 federal consolidated income tax returns. As of June 30, 2017, the examination was complete. The settlement and payment that resulted from the examination did not have a material effect on our results of operations. The Company’s effective income tax rate was ( 0.8% ) for the first six months of 2017. The effective tax rate differs from the federal tax rate of 35 % due to state income taxes, foreign tax rate differences, foreign losses not deductible for U.S. income tax purposes, provisions for interest charges for uncertain income tax positions, stock compensation shortfalls and changes in valuation allowances related to deferred tax assets . The foreign operating losses may ultimately be deductible in the countries in which they occurred; however the Company has not recorded a deferred tax asset for these losses due to uncertainty regarding the eventual realization of the benefit. The effect of the foreign operations was an overall rate decrease of approximately ( 18.2% ) for the six months ended June 30, 2017 . There were no additional uncertain tax positions identified in the first six months of 2017. The Company's effective income tax rate for the six months ended June 30, 2016 was ( 5.0% ), and differed from the federal tax rate due to state income taxes, foreign tax rate differences, foreign losses not deductible for U.S. income tax purposes, provisions for interest charges for uncertain income tax positions, and changes in valuation allowances related to deferred tax assets.

Net Loss Per Share [Abstract]
Net Loss Per Share	NOTE 12 – NET LOSS PER SHARE  Basic net income per common share is based on the weighted average number of common shares outstanding during each year. Diluted net income per common share takes into effect the dilutive effect of potential common shares outstanding. The Company’s only potential common shares outstanding are stock options and shares associated with the long-term incentive compensation plans, which resulted in no dilutive effect for the three and six month periods ended June 30, 2017 and 2016. The Company calculates the dilutive effect of outstanding options using the treasury stock method. Due to the net losses in the first three and six months of 2017 and 2016, there was no dilutive impact from stock options or unvested shares. Options totaling 888,042 were excluded from the calculation of diluted earnings per share for the three months and six ended June 30, 2017 because the exercise price was greater than the average market price of common stock during the period and deferred stock awards totaling 187,958 shares would not have been included for the three and six months ended June 30, 2017 because of unmet performance conditions. Options totaling 896,192 and 739,870 were excluded from the calculation of diluted earnings per share for the three and six months ended June 30 , 2016 because the exercise price was greater than the average market price of common stock during the period and deferred stock awards totaling 159,689 shares would not have been included for the three and six months ended June 30 , 201 6 because of unmet performance conditions.

Fair Value Measurements [Abstract]
Fair Value Measurements	NOTE 1 3 – FAIR VALUE MEASUREMENTS The accounting guidance establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 – Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date. Level 2 – Observable inputs such as quoted prices for similar instruments and quoted prices in markets that are not active, and inputs that are directly observable or can be corroborated by observable market data. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, such as treasury securities with pricing interpolated from recent trades of similar securities, or priced with models using highly observable inputs, such as commodity options priced using observable forward prices and volatilities. Level 3 – Significant inputs to pricing that have little or no observability as of the reporting date. The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation, such as the complex and subjective models and forecasts used to determine the fair value of financial instruments. As discussed in Note 5, we tested our goodwill for impairment as of April 1, 2017. As part of this impairment testing, the Company determined the fair value of the net assets of the JDL Technologies reporting unit, based primarily on discounted cash flows and forecasted future operating results, which represent Level 3 inputs. As a result of our analysis, the Company recorded a non-cash impairment charge of $ 1,463,000 to fully impair goodwill. A reconciliation of the beginning and ending balances of goodwill are included in Note 5. Financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2017 and December 31, 2016 , are summarized below:     June 30, 2017   Level 1 Level 2 Level 3 Total Fair Value   Cash equivalents:  Money Market funds $ 8,245,000 $ - $ - $ 8,245,000  Subtotal 8,245,000 - - 8,245,000   Short-term investments:  Certificates of deposit - 1,445,000 - 1,445,000  Subtotal - 1,445,000 - 1,445,000   Total $ 8,245,000 $ 1,445,000 $ - $ 9,690,000      December 31, 2016   Level 1 Level 2 Level 3 Total Fair Value   Cash equivalents:  Money Market funds $ 3,851,000 $ - $ - $ 3,851,000  Subtotal 3,851,000 - - 3,851,000   Short-term investments:  Certificates of deposit - 4,294,000 - 4,294,000  Corporate Notes/Bonds - 1,511,000 - 1,511,000  Subtotal - 5,805,000 - 5,805,000   Total $ 3,851,000 $ 5,805,000 $ - $ 9,656,000  We record transfers between levels of the fair value hierarchy, if necessary, at the end of the reporting period. There were no transfers between levels during the six months ended June 30, 2017 .

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	NOTE 15 – RECENT ACCOUNTING PRONOUNCEMENTS  In May 2014, the Financial Accounting Standards Board (FASB) issued a new accounting standard update on revenue recognition from contracts with customers. The new guidance will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. According to the new guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. As a result of the FASB’s July 2015 deferral of the standard’s required implementation date, the guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. We plan to adopt the modified retrospective approach. We are still evaluating the impact of this adoption and anticipate that the most significant impact will be within our JDL Technologies segment.  In July 2015, the FASB issued an accounting standard on inventory, which simplifies the subsequent measurement of inventory by requiring entities to measure inventory at the lower of cost or net realizable value, except for inventory measured using the last-in, first-out (LIFO) or the retail inventory methods. This standard requires entities to compare the cost of inventory to one measure – net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The standard is effective for the annual period beginning after December 15, 2016 and interim periods within those annual periods, with early adoption permitted, and is to be applied prospectively. The Company adopted this standard in the first quarter of 2017 with no material impact on its consolidated financial statements.  In November 2015, the FASB issued an accounting standard on deferred taxes, which removes the requirement to present deferred tax assets and liabilities as current and noncurrent on the balance sheet based on the classification of the related asset or liability, and instead requires classification of all deferred tax assets and liabilities as noncurrent. This guidance will be effective for interim and annual reporting periods beginning after December 15, 2016, and early adoption is permitted. The Company adopted this guidance in the first quarter of 2017 and other than the prescribed classification of all deferred tax assets and liabilities as noncurrent, there was no material impact on its consolidated financial statements.  In February 2016, the FASB issued new accounting requirements regarding accounting for leases, which requires an entity to recognize both assets and liabilities arising from financing and operating leases, along with additional qualitative and quantitative disclosures. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period, and early adoption is permitted. We have not yet determined the potential effects on our financial condition or results of operations.  In March 2016, the FASB issued a new accounting standard that changed certain aspects of accounting for share-based payments to employees, including the accounting for income taxes, forfeitures and statutory withholding requirements, as well as classification in the statement of cash flows. The new standard is effective for annual and interim periods beginning after December 15, 2016. The Company adopted this standard during the first quarter of 2017 with no material impact on our financial condition or results of operations.  In August 2016, the FASB issued new accounting guidance regarding the classification of cash receipts and payments in the Statement of Cash Flows. This guidance is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the Consolidated Statement of Cash Flows by providing guidance on eight specific cash flow issues. The new standard is effective retrospectively on January 1, 2018, with early adoption permitted. We have not yet determined the impact this standard will have on our financial condition or results of operations.  In January 2017, the FASB issued new accounting guidance regarding the simplification of the test for goodwill impairment. The new standard eliminates the quantitative goodwill impairment analysis requirement to determine the fair value of individual assets and liabilities of a reporting unit to determine the amount of any goodwill impairment and instead permits an entity to recognize goodwill impairment loss as the excess of a reporting unit's carrying value over the estimated fair value of the reporting unit, to the extent this amount does not exceed the carrying amount of goodwill. The new guidance continues to allow an entity to perform a qualitative assessment over goodwill impairment indicators in lieu of a quantitative assessment in certain situations. The standard will be effective for annual and interim periods beginning January 1, 2020, with early adoption permitted. The Company adopted this standard during 2017. As noted above in Note 5, the Company analyzed the reporting unit that had the goodwill and also analyzed the Company as a whole, including the Company’s four separate reporting units. Based on this analysis of comparing the fair value of each reporting unit to the book value and comparing the Company’s overall book value with its market capitalization, the Company determined that the book value exceeds the overall fair value of the reporting units as well as the Company’s overall market value. As a result, the Company recorded a goodwill impairment charge totaling $1,463,000 during the second quarter of 2017.

Summary Of Significant Accounting Policies [Abstract]
Description Of Business	Description of Business  Communications Systems, Inc. (herein collectively called “CSI” or the “Company”) is a Minnesota corporation organized in 1969 that operates primarily as a holding company conducting its business through four business units having operations in the United States, Costa Rica, and the United Kingdom. CSI is principally engaged through its Suttle business unit in the manufacture and sale of connectivity infrastructure products for broadband and voice communications and through its Transition Networks business unit in the manufacture of core media conversion products, Ethernet switches, and other connectivity and data transmission products. Through its JDL Technologies business unit the Company provides technology solutions including virtualization, managed services, wired and wireless network design and implementation, HIPAA-compliant IT services, and converged infrastructure configuration and deployment. Through its Net2Edge business unit, the Company enables telecommunications carriers to connect legacy networks to high-speed services.   The Company classifies its businesses into four segments corresponding to the Suttle, Transition Networks, JDL Technologies and Net2Edge business units. Non-allocated general and administrative expenses are separately accounted for as “Other” in the Company’s segment reporting. Intersegment revenues are eliminated upon consolidation.
Financial Statement Presentation	Financial Statement Presentation  The condensed consolidated balance sheets and condensed consolidated statement of changes in stockholders’ equity as of June 30, 2017 and the related condensed consolidated statements of loss and comprehensive loss, and the condensed consolidated statements of cash flows for the periods ended June 30, 2017 and 2016 have been prepared by Company management . In the opinion of management, all adjustments (which include only normal recurring adjustments, except where noted) necessary to present fairly the financial position, results of operations, and cash flows at June 30, 2017 and 2016 and for the periods then ended have been made.  Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted. We recommend these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s December 31, 2016 Annual Report to Shareholders on Form 10-K. The results of operations for the period ended June 30, 2017 are not necessarily indicative of operating results for the entire year.  The presentation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenues and expenses during the reporting period. The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates.  Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 , appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference.
Accumulated Other Comprehensive Loss	Accumulated Other Comprehensive Loss  The components of accumulated other comprehensive loss, net of tax, are as follows:       Foreign Currency Translation Unrealized (loss)/gain on securities Accumulated Other Comprehensive Loss  December 31, 2016 $ (704,000) $ 17,000 $ (687,000)   Net current period change 33,000 (3,000) 30,000   June 30, 2017 $ (671,000) $ 14,000 $ (657,000)  The Company recognized $4,238,000 in foreign currency translation losses within the income statement during the first quarter of 2016 due to the substantial liquidation of our Austin Taylor facility in the U.K. Refer to Note 1 1 for further information regarding the pension liability adjustment recognized in income in the first quarter of 2016.
