Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 - Summary of Significant Accounting Policies (a) The Company and Basis of Consolidation Blonder Tongue Laboratories, Inc. (together with its consolidated subsidiaries, the “ Company (b) Cash and Cash Equivalents The Company considers all highly liquid debt investments with a maturity of less than three months at purchase to be cash equivalents. The Company did not have any cash equivalents at December 31, 2018 and 2017. Cash balances at financial institutions are insured by the Federal Deposit Insurance Corporation (“ FDIC (c) Accounts Receivable and Allowance for Doubtful accounts Accounts receivable are customer obligations due under normal trade terms. The Company sells its products primarily to distributors and private cable operators. The Company performs continuing credit evaluations of its customers’ financial condition and although the Company generally does not require collateral, letters of credit may be required from its customers in certain circumstances. Senior management reviews accounts receivable on a monthly basis to determine if any receivables will potentially be uncollectible. The Company includes any accounts receivable balances that are determined to be uncollectible, along with a general reserve based on historical experience, in its overall allowance for doubtful accounts. (d) Inventories Inventories are stated at the lower of cost, determined by the first-in, first-out (“ FIFO The Company periodically analyzes anticipated product sales based on historical results, current backlog and marketing plans. Based on these analyses, the Company anticipates that certain products will not be sold during the next twelve months. Inventories that are not anticipated to be sold in the next twelve months, have been classified as non-current. The Company continually analyzes its slow-moving and excess inventories. Based on historical and projected sales volumes and anticipated selling prices, the Company establishes reserves. Inventory that is in excess of current and projected use is reduced by an allowance to a level that approximates its estimate of future demand. Products that are determined to be obsolete are written down to net realizable value. (e) Property, Plant and Equipment Property, plant and equipment are stated at cost. The Company provides for depreciation generally on the straight-line method based upon estimated useful lives of 3 to 5 years for office equipment, 5 to 7 years for furniture and fixtures, 6 to 10 years for machinery and equipment, 10 to 15 years for building improvements and 40 years for the manufacturing and administrative office facility. (f) Goodwill and Other Intangible Assets The Company accounts for goodwill and intangible assets in accordance with Accounting Standards Codification (“ ASC ASC 350 Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combinations. Accounting principles generally accepted in the United States (“ GAAP The Company’s business includes one goodwill reporting unit. The Company annually reviews goodwill for possible impairment by comparing the fair value of the reporting unit to the carrying value of the assets. If the fair value exceeds the carrying value of the net asset, no goodwill impairment is deemed to exist. If the fair value does not exceed the carrying value, goodwill is tested for impairment and written down to its implied fair value if it is determined to be impaired. The Company performed its annual goodwill impairment test on December 31, 2018. Based upon its qualitative assessment, the Company determined that goodwill was not impaired. The Company considers its trade name to have an indefinite life and in accordance with ASC 350, will not be amortized and will be reviewed annually for impairment. The components of intangible assets that are carried at cost less accumulated amortization at December 31, 2018 are as follows: Description Cost Accumulated Net Amount Customer relationships $ 1,365 $ 944 $ 421 Proprietary technology 349 242 107 Non-compete agreements 248 248 - Amortized intangible assets 1,962 1,434 528 Non-Amortized Trade name 741 - 741 Total $ 2,703 $ 1,434 $ 1,269 The components of intangible assets that are carried at cost less accumulated amortization at December 31, 2017 are as follows: Description Cost Accumulated Net Amount Customer relationships $ 1,365 $ 808 $ 557 Proprietary technology 349 206 143 Non-compete agreements 248 248 - Amortized intangible assets 1,962 1,262 700 Non-Amortized Trade name 741 - 741 Total $ 2,703 $ 1,262 $ 1,441 Amortization is computed utilizing the straight-line method over the estimated useful lives of 10 years for customer relationships, 10 years for proprietary technology, and 3 years for non-compete agreements. Amortization expense for intangible assets was $171 for both years ended December 31, 2018 and 2017, respectively. Intangible asset amortization is projected to be approximately $171 per year in 2019, 2020 and 2021, respectively and $15 in 2022. (g) Long-Lived Assets The Company continually monitors events and changes in circumstances that could indicate carrying amounts of the long-lived assets, including intangible assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses recoverability by determining whether the carrying value of such assets will be recovered through the undiscounted expected future cash flows. If the future undiscounted cash flows are less than the carrying amount of these assets, an impairment loss is recognized based on the excess of the carrying amount over the fair value of the assets. The Company did not recognize any intangible asset impairment charges in 2018 and 2017. (h) Treasury Stock Treasury Stock is recorded at cost. Gains and losses on subsequent reissuance are recorded as increases or decreases to additional paid-in capital with losses in excess of previously recorded gains charged directly to retained earnings. During 2018 and 2017, 81 shares and 92 shares, respectively of common stock were reissued from treasury. (i) Significant Risks and Uncertainties The preparation of financial statements in conformity with GAAP 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 date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s significant estimates include stock compensation and reserves related to accounts receivable, inventory and deferred tax assets. Actual results could differ from those estimates. At December 31, 2018, approximately 28% of the Company’s employees were covered by a collective bargaining agreement, that is scheduled to expire in February 2023. The Company’s digital video headend products accounted for approximately 48% and 41% of the Company’s revenues in the years ended December 31, 2018 and 2017, respectively. (j) Royalty and License Expense The Company records royalty expense, as applicable, when the related products are sold. Royalty expense is recorded as a component of selling expenses. Royalty expense was $45 and $77 for the years ended December 31, 2018 and 2017, respectively. The Company amortizes license fees over the life of the relevant contract. The components of intangible assets consisting of license agreements that are carried at cost less accumulated amortization are as follows: December 31, 2018 2017 License agreements $ 6,005 $ 5,985 Accumulated amortization (5,993 ) (5,956 ) $ 12 $ 29 Amortization of license fees is computed utilizing the straight-line method over the estimated useful life of 1 to 2 years. Amortization expense for license fees was $38 and $150 in the years ended December 31, 2018 and 2017, respectively. Amortization expense for license fees is projected to be approximately $12 in the year ending December 31, 2019. (k) Foreign Exchange The Company uses the United States dollar as its functional and reporting currency since the majority of the Company’s revenues, expenses, assets and liabilities are in the United States and the focus of the Company’s operations is in that country. Assets and liabilities in foreign currencies are translated using the exchange rate at the balance sheet date. Revenues and expenses are translated at average rates of exchange during the year. Gains and losses from foreign currency transactions and translation for the years ended December 31, 2018 and 2017 and cumulative translation gains and losses as of December 31, 2018 and 2017 were not material. (l) Research and Development Research and development expenditures for the Company’s projects are expensed as incurred. (m) Revenue Recognition The Company generates revenue through the sale of products and services. Revenue is recognized based on the following steps: (i) identification of contract with customer; (ii) determination of performance obligations; (iii) measurement of the transaction price; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. Revenue from the sale of products and services is recorded when the performance obligation is fulfilled, usually at the time of shipment or when the service is provided, at the net sales price (transaction price). Estimates of variable consideration, such as volume discounts and rebates, are reviewed and revised periodically by management. The Company elected to present revenue net of sales tax and other similar taxes and account for shipping and handling activities as fulfillment costs rather than separate performance obligations. Payments are typically due in 30 days, following delivery of products or completion of services. The Company provides a three-year warranty on most products. Warranty expense was de minimis (n) Stock-based compensation The Company computes stock-based compensation in accordance with authoritative guidance. The Company uses the Black-Scholes-Merton option pricing model to determine the fair value of its stock options. The Black-Scholes-Merton option-pricing model includes various assumptions, including the fair market value of the common stock of the Company, expected life of stock options, the expected volatility and the expected risk-free interest rate, among others. These assumptions reflect the Company’s best estimates, but they involve inherent uncertainties based on market conditions generally outside the control of the Company. Forfeitures are recorded when they occur. As a result, if other assumptions had been used, stock-based compensation cost, as determined in accordance with authoritative guidance, could have been materially impacted. Furthermore, if the Company uses different assumptions on future grants, stock-based compensation cost could be materially affected in future periods. (o) Income Taxes The Company accounts for income taxes under the provisions of the Financial Accounting Standards Board (“ FASB ASC Topic 740 The Company will classify as income tax expense any interest and penalties recognized in accordance with ASC Topic 740. The Company files income tax returns primarily in the United States and New Jersey, along with certain other jurisdictions. (p) Earnings (loss) Per Share Earnings (loss) per share are calculated in accordance with ASC Topic 260 “Earnings Per Share,” which provides for the calculation of “basic” and “diluted” earnings (loss) per share. Basic earnings (loss) per share includes no dilution and is computed by dividing net earnings by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflect, in periods in which they have a dilutive effect, the effect of potential issuances of common shares. The diluted share base excludes incremental shares related to stock options, warrants and convertible debt of 1,157. 100 and 257 and 1,256, 100 and 1,156 for the year ended December 31, 2018 and 2017, respectively. These shares were excluded due to their antidilutive effect. (q) Other Comprehensive Income (loss) Comprehensive income (loss) is a measure of income which includes both net loss and other comprehensive income (loss). Other comprehensive income (loss) results from items deferred from recognition into the statement of operations and principally consists of unrecognized pension losses net of taxes. Accumulated other comprehensive loss is separately presented on the Company’s consolidated balance sheet as part of stockholders’ equity. (r) Subsequent Events The Company evaluates events that have occurred after the balance sheet date but before the financial statements are issued. Based upon the evaluation, the Company did not identify any additional recognized or non-recognized subsequent events that would require adjustment to or disclosure in the consolidated financial statements. (s) Adoption of Recent Accounting Pronouncements On January 1, 2018, the Company adopted Accounting Standards Update (“ ASU Revenue from Contracts with Customers (“Topic 606” Revenue Recognition Topic 605 In May 2017, the FASB issued ASU No. 2017-09, Compensation–Stock Compensation (Topic 718): Scope of Modification Accounting (t) Accounting Pronouncements Issued But Not Yet Effective In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation (“ Topic 718” ): Improvements to Nonemployee Share-Based Payment Accounting In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) Codification Improvements to Topic 842, Leases In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other Topic 350 Simplifying the Test for Goodwill Impairment In February 2018, the FASB issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income Topic 220 : Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ASU 2018-02 In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) changes the impairment model for most financial assets, and will require the use of an expected loss model in place of the currently used incurred loss method. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The update to the standard is effective for interim and annual periods beginning after December 15, 2019. The Company is currently evaluating the effect this new standard will have on its financial position, results of operations or financial statement disclosure.

Risks and Uncertainties [Abstract]
Concentration of Credit Risk	Note 10 - Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash deposits and trade accounts receivable. Credit risk with respect to trade accounts receivable was concentrated with three and four of the Company's customers in 2018 and 2017, respectively. These customers accounted for approximately 47% and 65% of the Company's outstanding trade accounts receivable at December 31, 2018 and 2017, respectively. The Company performs ongoing credit evaluations of its customers' financial condition, uses credit insurance and requires collateral, such as letters of credit, to mitigate its credit risk. The deterioration of the financial condition of one or more of its major customers could adversely impact the Company's operations. From time to time where the Company determines that circumstances warrant, such as when a customer agrees to commit to a large blanket purchase order, the Company extends payment terms beyond its standard payment terms.

The Company estimates the fair value of performance stock option awards using the Black-Scholes-Merton option pricing model. Compensation expense for stock option awards is amortized on a straight-line basis over the awards' vesting period. The expected term of the stock options represents the average period the stock options are expected to remain outstanding and is based on the expected term calculated using the approach prescribed by the Securities and Exchange Commission's Staff Accounting Bulletin No. 110 for "plain vanilla" options. The expected stock price volatility for the Company's stock options was determined by using an average of the historical volatilities of the Company. The Company will continue to analyze the stock price volatility and expected term assumptions as more data for the Company's common stock and exercise patterns become available. The risk-free interest rate assumption is based on the U.S. Treasury instruments whose term was consistent with the expected term of the Company's stock options. The expected dividend assumption is based on the Company's history and expectation of dividend payouts. The Company does not estimate forfeitures based on historical experience but rather reduces compensation expense when they occur. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service periods of the respective awards. The fair value of employee stock options was estimated using the following weighted-average assumptions: Years ended December 31, 2018 2017 Fair value of the company's common stock on date of grant $ 0.95 $ 0.54 Expected term 6.5 years 6.5 years Risk free interest rate 2.92 % 2.02 % Dividend yield 0.00 % 0.00 % Volatility 79.0 % 79.0 % Fair value of options granted $ 0.68 $ 0.38 The following table summarizes total stock-based compensation costs recognized for the years ended December 31, 2018 and 2017: Years ended December 31, 2018 2017 Cost of goods sold $ 38 $ 34 Selling expenses 74 33 General and administrative 263 274 Research and development 118 45 Total $ 493 $ 386 The following table summarizes information about stock-based awards outstanding for the year ended December 31, 2018: Plan Stock Restricted Total 2016 Employee Plan 1,452 48 1,500 2016 Director Plan 199 - 199 Other 500 500 2005 Employee Plan 1,181 88 1,269 2005 Director Plan 324 - 324 3,656 136 3,792 Stock-based awards available for grant as of December 31, 2018 1,271 Stock options award activity for the year ended December 31, 2018 is as follows: Number of Weighted- Weighted- Aggregate Outstanding at January 1, 2018 2,269 $ 0.83 Options granted 1,546 0.95 Options exercised (94 ) 0.70 Options forfeited (23 ) 0.80 Options expired (42 ) 1.23 Outstanding at December 31, 2018 3,656 $ 0.88 7.4 $ 1,023 Exercisable at December 31, 2018 1,592 $ 0.97 5.3 $ 397 During the year ended December 31, 2018, the Company granted options under the 2016 Employee Plan, the 2016 Director Plan, the 2005 Employee Plan as well as non plan grants to purchase 1,546 shares of common stock to its employees and directors. The fair value of these options was approximately $1,051. The aggregate intrinsic value of stock options is calculated as the difference between exercise price of the underlying stock options and the fair value of the Company's common stock or $1.11 per share at December 31, 2018. Restricted stock award activity is as follows: Number of Weighted- Unvested restricted stock awards outstanding at January1, 2018 381 $ 0.64 Restricted stock awards granted 476 1.06 Restricted stock awards vested (315 ) 0.66 Restricted stock awards forfeited (406 ) 1.10 Unvested restricted stock awards outstanding at December 31, 2018 136 $ 0.71 During the year ended December 31, 2018, the Company granted restricted stock awards under the 2016 Employee Plan, the 2016 Director Plan, the 2005 Employee Plan as well as non plan grants of 476 shares of common stock to its employees. The fair value of these awards was approximately $506. The Company does not capitalize any cost associated with stock-based compensation. The Company issues new shares of common stock (or reduces the amount of treasury stock) upon exercise of stock options or release of restricted stock awards.

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and taxing strategies in making this assessment. The decision to record this valuation allowance was based on management evaluating all positive and negative evidence. The significant negative evidence includes a loss for the current year, a cumulative pre-tax loss for the three years ended December 31, 2018, the inability to carryback the net operating losses, limited future reversals of existing temporary differences and the limited availability of tax planning strategies. The Company expects to continue to provide a full valuation allowance until, or unless, it can sustain a level of profitability that demonstrates its ability to utilize these assets. The Company had no change in its liability for uncertain tax position during 2018 and no liabilities for uncertain tax positions as of December 31, 2018. ASC 740 discusses the classification of related interest and penalties on income taxes. The Company's policy is to record interest and penalties incurred in connection with income taxes as a component of income tax expense. No interest or penalties were recorded during the years ended December 31, 2018 and 2017. The Company is required to file U.S. federal and state income tax returns. These returns are subject to audit by tax authorities beginning with the year ended December 31, 2015.

Accounts Receivable and Allowance for Doubtful accounts	(c) Accounts Receivable and Allowance for Doubtful accounts Accounts receivable are customer obligations due under normal trade terms. The Company sells its products primarily to distributors and private cable operators. The Company performs continuing credit evaluations of its customers’ financial condition and although the Company generally does not require collateral, letters of credit may be required from its customers in certain circumstances. Senior management reviews accounts receivable on a monthly basis to determine if any receivables will potentially be uncollectible. The Company includes any accounts receivable balances that are determined to be uncollectible, along with a general reserve based on historical experience, in its overall allowance for doubtful accounts.
Inventories	(d) Inventories Inventories are stated at the lower of cost, determined by the first-in, first-out (“ FIFO The Company periodically analyzes anticipated product sales based on historical results, current backlog and marketing plans. Based on these analyses, the Company anticipates that certain products will not be sold during the next twelve months. Inventories that are not anticipated to be sold in the next twelve months, have been classified as non-current. The Company continually analyzes its slow-moving and excess inventories. Based on historical and projected sales volumes and anticipated selling prices, the Company establishes reserves. Inventory that is in excess of current and projected use is reduced by an allowance to a level that approximates its estimate of future demand. Products that are determined to be obsolete are written down to net realizable value.
Property, Plant and Equipment	(e) Property, Plant and Equipment Property, plant and equipment are stated at cost. The Company provides for depreciation generally on the straight-line method based upon estimated useful lives of 3 to 5 years for office equipment, 5 to 7 years for furniture and fixtures, 6 to 10 years for machinery and equipment, 10 to 15 years for building improvements and 40 years for the manufacturing and administrative office facility.
Goodwill and Other Intangible Assets	(f) Goodwill and Other Intangible Assets The Company accounts for goodwill and intangible assets in accordance with Accounting Standards Codification (“ ASC ASC 350 Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combinations. Accounting principles generally accepted in the United States (“ GAAP The Company’s business includes one goodwill reporting unit. The Company annually reviews goodwill for possible impairment by comparing the fair value of the reporting unit to the carrying value of the assets. If the fair value exceeds the carrying value of the net asset, no goodwill impairment is deemed to exist. If the fair value does not exceed the carrying value, goodwill is tested for impairment and written down to its implied fair value if it is determined to be impaired. The Company performed its annual goodwill impairment test on December 31, 2018. Based upon its qualitative assessment, the Company determined that goodwill was not impaired. The Company considers its trade name to have an indefinite life and in accordance with ASC 350, will not be amortized and will be reviewed annually for impairment. The components of intangible assets that are carried at cost less accumulated amortization at December 31, 2018 are as follows: Description Cost Accumulated Net Amount Customer relationships $ 1,365 $ 944 $ 421 Proprietary technology 349 242 107 Non-compete agreements 248 248 - Amortized intangible assets 1,962 1,434 528 Non-Amortized Trade name 741 - 741 Total $ 2,703 $ 1,434 $ 1,269 The components of intangible assets that are carried at cost less accumulated amortization at December 31, 2017 are as follows: Description Cost Accumulated Net Amount Customer relationships $ 1,365 $ 808 $ 557 Proprietary technology 349 206 143 Non-compete agreements 248 248 - Amortized intangible assets 1,962 1,262 700 Non-Amortized Trade name 741 - 741 Total $ 2,703 $ 1,262 $ 1,441 Amortization is computed utilizing the straight-line method over the estimated useful lives of 10 years for customer relationships, 10 years for proprietary technology, and 3 years for non-compete agreements. Amortization expense for intangible assets was $171 for both years ended December 31, 2018 and 2017, respectively. Intangible asset amortization is projected to be approximately $171 per year in 2019, 2020 and 2021, respectively and $15 in 2022.
Long-Lived Assets	(g) Long-Lived Assets The Company continually monitors events and changes in circumstances that could indicate carrying amounts of the long-lived assets, including intangible assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses recoverability by determining whether the carrying value of such assets will be recovered through the undiscounted expected future cash flows. If the future undiscounted cash flows are less than the carrying amount of these assets, an impairment loss is recognized based on the excess of the carrying amount over the fair value of the assets. The Company did not recognize any intangible asset impairment charges in 2018 and 2017.
Treasury Stock	(h) Treasury Stock Treasury Stock is recorded at cost. Gains and losses on subsequent reissuance are recorded as increases or decreases to additional paid-in capital with losses in excess of previously recorded gains charged directly to retained earnings. During 2018 and 2017, 81 shares and 92 shares, respectively of common stock were reissued from treasury.
Significant Risks and Uncertainties	(i) Significant Risks and Uncertainties The preparation of financial statements in conformity with GAAP 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 date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s significant estimates include stock compensation and reserves related to accounts receivable, inventory and deferred tax assets. Actual results could differ from those estimates. At December 31, 2018, approximately 28% of the Company’s employees were covered by a collective bargaining agreement, that is scheduled to expire in February 2023. The Company’s digital video headend products accounted for approximately 48% and 41% of the Company’s revenues in the years ended December 31, 2018 and 2017, respectively.
Royalty and License Expense	(j) Royalty and License Expense The Company records royalty expense, as applicable, when the related products are sold. Royalty expense is recorded as a component of selling expenses. Royalty expense was $45 and $77 for the years ended December 31, 2018 and 2017, respectively. The Company amortizes license fees over the life of the relevant contract. The components of intangible assets consisting of license agreements that are carried at cost less accumulated amortization are as follows: December 31, 2018 2017 License agreements $ 6,005 $ 5,985 Accumulated amortization (5,993 ) (5,956 ) $ 12 $ 29 Amortization of license fees is computed utilizing the straight-line method over the estimated useful life of 1 to 2 years. Amortization expense for license fees was $38 and $150 in the years ended December 31, 2018 and 2017, respectively. Amortization expense for license fees is projected to be approximately $12 in the year ending December 31, 2019.
Foreign Exchange	(k) Foreign Exchange The Company uses the United States dollar as its functional and reporting currency since the majority of the Company’s revenues, expenses, assets and liabilities are in the United States and the focus of the Company’s operations is in that country. Assets and liabilities in foreign currencies are translated using the exchange rate at the balance sheet date. Revenues and expenses are translated at average rates of exchange during the year. Gains and losses from foreign currency transactions and translation for the years ended December 31, 2018 and 2017 and cumulative translation gains and losses as of December 31, 2018 and 2017 were not material.
Research and Development	(l) Research and Development Research and development expenditures for the Company’s projects are expensed as incurred.
Revenue Recognition	(m) Revenue Recognition The Company generates revenue through the sale of products and services. Revenue is recognized based on the following steps: (i) identification of contract with customer; (ii) determination of performance obligations; (iii) measurement of the transaction price; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. Revenue from the sale of products and services is recorded when the performance obligation is fulfilled, usually at the time of shipment or when the service is provided, at the net sales price (transaction price). Estimates of variable consideration, such as volume discounts and rebates, are reviewed and revised periodically by management. The Company elected to present revenue net of sales tax and other similar taxes and account for shipping and handling activities as fulfillment costs rather than separate performance obligations. Payments are typically due in 30 days, following delivery of products or completion of services. The Company provides a three-year warranty on most products. Warranty expense was de minimis
Stock-based compensation	(n) Stock-based compensation The Company computes stock-based compensation in accordance with authoritative guidance. The Company uses the Black-Scholes-Merton option pricing model to determine the fair value of its stock options. The Black-Scholes-Merton option-pricing model includes various assumptions, including the fair market value of the common stock of the Company, expected life of stock options, the expected volatility and the expected risk-free interest rate, among others. These assumptions reflect the Company’s best estimates, but they involve inherent uncertainties based on market conditions generally outside the control of the Company. Forfeitures are recorded when they occur. As a result, if other assumptions had been used, stock-based compensation cost, as determined in accordance with authoritative guidance, could have been materially impacted. Furthermore, if the Company uses different assumptions on future grants, stock-based compensation cost could be materially affected in future periods.
Income Taxes	(o) Income Taxes The Company accounts for income taxes under the provisions of the Financial Accounting Standards Board (“ FASB ASC Topic 740 The Company will classify as income tax expense any interest and penalties recognized in accordance with ASC Topic 740. The Company files income tax returns primarily in the United States and New Jersey, along with certain other jurisdictions.
Earnings (loss) Per Share	(p) Earnings (loss) Per Share Earnings (loss) per share are calculated in accordance with ASC Topic 260 “Earnings Per Share,” which provides for the calculation of “basic” and “diluted” earnings (loss) per share. Basic earnings (loss) per share includes no dilution and is computed by dividing net earnings by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflect, in periods in which they have a dilutive effect, the effect of potential issuances of common shares. The diluted share base excludes incremental shares related to stock options, warrants and convertible debt of 1,157. 100 and 257 and 1,256, 100 and 1,156 for the year ended December 31, 2018 and 2017, respectively. These shares were excluded due to their antidilutive effect.
Other Comprehensive Income (loss)	(q) Other Comprehensive Income (loss) Comprehensive income (loss) is a measure of income which includes both net loss and other comprehensive income (loss). Other comprehensive income (loss) results from items deferred from recognition into the statement of operations and principally consists of unrecognized pension losses net of taxes. Accumulated other comprehensive loss is separately presented on the Company’s consolidated balance sheet as part of stockholders’ equity.
Subsequent Events	(r) Subsequent Events The Company evaluates events that have occurred after the balance sheet date but before the financial statements are issued. Based upon the evaluation, the Company did not identify any additional recognized or non-recognized subsequent events that would require adjustment to or disclosure in the consolidated financial statements.

Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The update to the standard is effective for interim and annual periods beginning after December 15, 2019. The Company is currently evaluating the effect this new standard will have on its financial position, results of operations or financial statement disclosure.
