Accounting Policies [Abstract]
Description of Company and Summary of Significant Accounting Policies	NOTE 1 - DESCRIPTION OF COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Organization and Basis of Presentation Wireless Telecom Group, Inc., a New Jersey corporation, together with its subsidiaries (“we”, “us”, “our” or the “Company”), is a global designer and manufacturer of advanced RF, microwave and millimeter wave components, modules, systems and instruments and currently markets its products and services worldwide under the Boonton, Microlab, Noisecom and CommAgility brands. Serving the wireless, telecommunication, satellite, military, aerospace, and semiconductor industries, Wireless Telecom Group products enable innovation across a wide range of traditional and emerging wireless technologies. With a unique set of high-performance products including peak power meters, signal analyzers, signal processing modules, long term evolution (“LTE”) physical layer (“PHY”) and stack software, power splitters and combiners, global positioning system (“GPS”) repeaters, public safety monitors, noise sources, and programmable noise generators, Wireless Telecom Group supports the development, testing, and deployment of wireless technologies around the globe. The consolidated financial statements include the accounts of Wireless Telecom Group, Inc., doing business as, and operating under the trade name, Noise Com, Inc. (“Noisecom”), and its wholly owned subsidiaries including Boonton Electronics Corporation (“Boonton”), Microlab/FXR (“Microlab”), Wireless Telecommunications Ltd. and CommAgility Limited (“CommAgility”). The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. The Consolidated Financial Statements have been prepared using accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany accounts and transactions have been eliminated in consolidation. The Company presents its operations in three reportable segments: (1) Network Solutions, (2) Test and Measurement and (3) Embedded Solutions. The Network Solutions segment is comprised of the operations of Microlab. The Test and Measurement segment is comprised of the operations of Boonton and Noisecom. The Embedded Solutions segment is comprised of the operations of CommAgility. Use of Estimates The accompanying financial statements have been prepared in accordance with U.S. GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Accordingly, actual results could differ from those estimates. The most significant estimates and assumptions include management’s analysis in support of inventory valuation, accounts receivable valuation, valuation of deferred tax assets, returns reserves, warranty accruals, intangible assets, estimated fair values of stock options and vesting periods of performance-based stock options and restricted stock. Concentrations of Credit Risk, Purchases and Fair Value Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable. Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated to a lesser extent through collateral such as letters of credit, bank guarantees or payment terms like cash in advance. For the years ended December 31, 2019 and 2018 one customer, from the Embedded Solutions segment, accounted for 24.8% and 22.0% of the Company’s total consolidated revenues, respectively. At December 31, 2019, one customer exceeded 10% of consolidated gross accounts receivable at 12.9%. At December 31, 2018 one customer exceeded 10% of consolidated gross accounts receivable at 32.1%. For the year ended December 31, 2019, three suppliers comprised or exceeded 10% of consolidated inventory purchases at 18%, 14%, and 10% respectively. For the year ended December 31, 2018 two suppliers comprised or exceeded 10% of consolidated inventory purchases at 15% and 13%, respectively. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with maturities of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist of operating accounts. Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. Estimated allowances for doubtful accounts are reviewed periodically taking into account the customer’s recent payment history, the customer’s current financial statements and other information regarding the customer’s credit worthiness. Account balances are charged off against the allowance when it is determined the receivable will not be recovered. Inventories Inventories are stated at the lower of cost (average cost) or net realizable value. Net realizable value is based upon an estimated average selling price reduced by estimated costs of completion, disposal and transportation. Reductions in inventory valuation are included in cost of revenues in the accompanying Consolidated Statements of Operations and Comprehensive Loss. Finished goods and work-in-process include material, labor and overhead expenses. The Company reviews inventory for excess and obsolescence based on best estimates of future demand, product lifecycle status and product development plans. The Company uses historical information along with these future estimates to reduce the inventory cost basis. Subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Inventory carrying value is net of inventory reserves of approximately $1.0 million as of December 31, 2019 and $1.9 million as of December 31, 2018. Inventories consist of (in thousands): December 31, 2019 December 31, 2018 Raw materials $ 4,023 $ 3,248 Work-in-process 406 557 Finished goods 2,896 3,079 $ 7,325 $ 6,884 Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets generally consist of income tax receivables, contract assets, prepaid insurance, prepaid maintenance agreements and the short term portion of debt issuance costs. The income tax receivable balance included in prepaid and other current assets was $1.1 million as of December 31, 2019 as compared to a balance of $0.8 million as of December 31, 2018. Property, Plant and Equipment Property, plant and equipment are reflected at cost, less accumulated depreciation. Depreciation and amortization are provided on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives for the property, plant and equipment are: Machinery and computer equipment 3-8 years Furniture and fixtures 5-7 years Transportation equipment 4 years Leasehold improvements are amortized over the shorter of the remaining term of the lease or the estimated economic life of the improvement. Repairs and maintenance are charged to operations as incurred; renewals and betterments are capitalized. Goodwill Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a purchase business combination. Goodwill is evaluated for impairment annually by first performing a qualitative evaluation of events and circumstances impacting the reporting unit to determine the likelihood of goodwill impairment. Based on that qualitative evaluation, if we determine it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, no further evaluation is necessary. Otherwise we perform a quantitative impairment test. As of December 31, 2019 the Company’s consolidated goodwill balance of $10.1 million is comprised of $1.4 million related to the Microlab reporting unit and $8.7 million related to the CommAgility reporting unit. The Company performed a qualitative assessment in the fourth quarter of 2019 of each reporting unit. The qualitative assessment of Microlab did not indicate any impairment of goodwill. As a result of declining future demand of the CommAgility’s signal processing hardware and the uncertainty associated with new product revenues to offset the signal processing hardware sale decline, the Company performed a quantitative impairment test of the goodwill of the CommAgility reporting unit. For goodwill impairment testing using the quantitative approach, the Company estimates the fair value of the selected reporting unit primarily through the use of a discounted cash flow model based on our best estimate of amounts and timing of future revenues and cash flows and our most recent business and strategic plans, and compares the estimated fair value to the carrying value of the reporting unit, including goodwill. If the fair value of the reporting unit exceeds the carrying value, no impairment charge is recorded. If the carrying value of the reporting unit exceeds the fair value an impairment charge is recorded to goodwill in the amount by which carrying value exceeds fair value. The discounted cash flow model requires judgmental assumptions about projected revenue growth, future operating margins, discount rates and terminal values over a multi-year period. There are inherent uncertainties related to these assumptions and management’s judgment in applying them to the analysis of goodwill impairment. While the Company believes it has made reasonable estimates and assumptions to calculate the fair value of its reporting units, it is possible a material change could occur. If actual results are not consistent with management’s estimates and assumptions, goodwill may be overstated and a charge would need to be taken against net earnings. Changes in our projections used in the discounted cash flow model could affect the estimated fair value of the Company’s reporting unit and could result in a goodwill impairment charge in a future period. In order to evaluate the sensitivity of the fair value calculations used in the quantitative goodwill impairment test, the Company applied a hypothetical 10% decrease to the fair value of the CommAgility reporting unit and compared those values to the carrying value. Based on this sensitivity analysis, the Company did not identify any goodwill impairment. Due to the many variables inherent in the estimation of a reporting unit’s fair value and the relative size of our recorded goodwill, differences in assumptions may have a material effect on the results of our impairment analysis. As of December 31, 2018 the Company’s consolidated goodwill balance of $9.8 million was comprised of $1.4 million related to the Microlab reporting unit and $8.4 million related to the CommAgility reporting unit. Management’s qualitative assessment performed in the fourth quarters of 2018 did not indicate any impairment of goodwill. Intangible and Long-lived Assets Intangible assets include patents, non-competition agreements, customer relationships and trademarks. Intangible assets with finite lives are amortized using the straight-line method over the estimated economic lives of the assets, which range from three to five years. Long-lived assets, including intangible assets with finite lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss for long-lived assets that management expects to hold and use is based on the estimated fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or estimated fair value less costs to sell. The estimated useful lives of intangible and long-lived assets are based on many factors including assumptions regarding the effects of obsolescence, demand, competition and other economic factors, expectations regarding the future use of the asset, and our historical experience with similar assets. The assumptions used to determine the estimated useful lives could change due to numerous factors including product demand, market conditions, technological developments, economic conditions and competition. Intangible assets determined to have indefinite useful lives are not amortized but are tested for impairment annually and more frequently if events occur or circumstances change that indicate an asset may be impaired. Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1 - Quoted prices in active markets for identical assets or liabilities. Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The carrying amounts of the Company’s financial instruments, including cash, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities. The Company’s term loan and revolving credit facility bear interest at a variable interest rate plus an applicable margin and, therefore, carrying amount approximates fair value. Foreign Currency Translation Assets and liabilities of non-U.S. subsidiaries that operate in a local currency environment, where the local currency is the functional currency, are translated from foreign currencies into U.S. dollars at period-end exchange rates while income and expenses are translated at the weighted average spot rate for the periods presented. Translation gains or losses related to net assets located outside the U.S. are shown as a component of accumulated other comprehensive income in the Consolidated Statements of Changes in Shareholders’ Equity. Gains and losses resulting from foreign currency transactions, which are denominated in currencies other than the Company’s functional currency, are included in the Consolidated Statements of Operations and Comprehensive Loss. Foreign exchange transaction losses were not material in fiscal 2019 and were $0.1 million in 2018. Other Comprehensive Income (Loss) Other comprehensive income (loss) is recorded directly to a separate section of shareholders’ equity in accumulated other comprehensive income and includes unrealized gains and losses excluded from net income/(loss). These unrealized gains and losses consist of changes in foreign currency translation. Research and Development Costs Research and development costs are charged to operations when incurred. The amounts charged to operations for the years ended December 31, 2019 and 2018 were $5.9 million and $4.9 million, respectively. Advertising Costs Advertising expenses are charged to operations during the year in which they are incurred and aggregated $0.1 million for the years ended December 31, 2019 and 2018. Stock-Based Compensation The Company follows the provisions of Accounting Standards Codification (“ASC”) 718, “Compensation – Stock Compensation” which requires that compensation expense be recognized, based on the fair value of the stock awards. The fair value of the stock awards is equal to the fair value of the Company’s stock on the date of grant. The fair value of options at the date of grant are estimated using the Black-Scholes option pricing model. When performance-based options are granted, the Company takes into consideration guidance under ASC 718 and SEC Staff Accounting Bulletin No. 107 (SAB 107) when determining assumptions. The expected option life is derived from assumed exercise rates based upon historical exercise patterns and represents the period of time that options granted are expected to be outstanding. The expected volatility is based upon historical volatility of our shares using daily price observations over an observation period that approximates the expected life of the options. The risk-free rate is based on the U.S. Treasury yield curve rate in effect at the time of grant for periods similar to the expected option life. The Company accounts for forfeitures when they occur. Management estimates are necessary in determining compensation expense for stock options with performance-based vesting criteria. Compensation expense for this type of stock-based award is recognized over the period from the date the performance conditions are determined to be probable of occurring through the implicit service period, which is the date the applicable conditions are expected to be met. If the performance conditions are not considered probable of being achieved, no expense is recognized until such time as the performance conditions are considered probable of being met, if ever. If the award is forfeited because the performance condition is not satisfied, previously recognized compensation cost is reversed. Management evaluates performance conditions on a quarterly basis. Income Taxes The Company records deferred taxes in accordance with ASC 740, “Accounting for Income Taxes”. This ASC requires recognition of deferred tax assets and liabilities for temporary differences between tax basis of assets and liabilities and the amounts at which they are carried in the financial statements, based upon the enacted rates in effect for the year in which the differences are expected to reverse. The Company establishes a valuation allowance when necessary to reduce deferred tax assets to the amount expected to be realized. The Company periodically assesses the value of its deferred tax asset, a majority of which has been generated by a history of net operating losses and determines the necessity for a valuation allowance. The Company evaluates which portion, if any, will more likely than not be realized by offsetting future taxable income, taking into consideration any limitations that may exist on its use of its net operating loss carry-forwards. Under ASC 740, the Company must recognize and disclose uncertain tax positions only if it is more-likely-than-not the tax position will be sustained on examination by the taxing authority, based on the technical merits of the position. The amounts recognized in the financial statements attributable to such position, if any, are recorded if there is a greater than 50% likelihood of being realized upon the ultimate resolution of the position. Based on the evaluations noted above, the Company has concluded that there are no significant uncertain tax positions requiring recognition or disclosure in its consolidated financial statements. Earnings (Loss) Per Common Share Basic earnings (loss) per share is calculated by dividing net income (loss) available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share is calculated by dividing net income (loss) available to common shareholders by the weighted average number of common shares outstanding for the period and, when dilutive, potential shares from stock options using the treasury stock method, the weighted average number of unvested restricted shares and the weighted-average number of restricted stock units outstanding for the period. Shares from stock options are included in the diluted earnings per share calculation only when options exercise prices are lower than the average market value of the common shares for the period presented. In periods with a net loss, the basic loss per share equals the diluted loss per share as all common stock equivalents are excluded from the per share calculation because they are anti-dilutive. In accordance with ASC 260, “Earnings Per Share”, the following table reconciles basic shares outstanding to fully diluted shares outstanding. For the Years Ended December 31, 2019 2018 Weighted average common shares outstanding 21,110,632 20,858,298 Potentially dilutive equity awards 522,996 707,492 Weighted average common shares outstanding, assuming dilution 21,633,628 21,565,790 The weighted average number of options to purchase common stock not included in diluted loss per share because the effects are anti-dilutive, or the performance condition was not met in 2019 was 1,324,548. The weighted average number of options to purchase common stock not included in diluted loss per share in 2018, because the effects are anti-dilutive or the performance condition was not met, was 285,000. Recent Accounting Pronouncements Adopted in 2019 In February 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) The Company adopted the requirements of the new standard effective January 1, 2019 using the modified retrospective transition method, which applies the provisions of the standard at the effective date without adjustment to the comparative periods presented. The Company adopted the following practical expedients and elected the following accounting policies related to this standard: ● Carry forward of historical lease classifications and accounting treatment; ● Short-term lease accounting policy election allowing lessees to not recognize right-of-use assets and liabilities for leases with a term of 12 months or less; and ● The option to not separate lease and non-lease components for certain equipment lease categories such as office printers and copiers. Adoption of this standard resulted in the recognition of operating lease right-of-use assets and corresponding lease liabilities of $1.9 million on the consolidated balance sheet as of January 1, 2019. The standard did not materially impact operating results or liquidity. Disclosures related to the amount, timing and uncertainty of cash flows arising from leases are included in Note 2. On June 20, 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.

Leases [Abstract]
Leases	NOTE 2 - LEASES The Company’s lease agreements consist of building leases for its operating locations and office equipment leases for printers and copiers with lease terms that range from less than 12 months to 8 years. At inception, the Company determines if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. The Company’s leases for office equipment such as printers and copiers contain lease and non-lease components (i.e. maintenance). The Company accounts for lease and non-lease components of office equipment as a single lease component. All of the Company’s leases are operating leases and are presented as right of use lease asset, short term lease liability and long term lease liability on the consolidated balance sheet as of December 31, 2019. These assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the lease term using the Company’s incremental borrowing rate. Short-term leases, which have an initial term of 12 months or less, are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the lease term and is included in cost of revenues and general and administrative expenses on the consolidated statement of operations and comprehensive income/(loss). An initial right-of-use asset of $1.9 million was recognized as a non-cash asset addition with the adoption of the new lease accounting standard. Subsequent to adoption of the new standard there were no new right-of-use assets recognized during the twelve months ended December 31, 2019. Cash paid for amounts included in the present value of operating lease liabilities was $0.5 million during the twelve months ended December 31, 2019 and is included in operating cash flows. Operating lease costs were $0.8 million during the twelve months ended December 2019. The following table presents information about the amount and timing of cash flows arising from the Company’s operating leases as of December 31, 2019.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	NOTE 3 – REVENUE Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for promised goods or services. The Company’s performance obligations are satisfied either over time or at a point in time. Revenue from performance obligations that transferred at a point in time accounted for approximately 99% and 95% of the Company’s total revenue for the twelve months ended December 31, 2019 and 2018, respectively. Nature of Products and Services Hardware The Company generally has one performance obligation in its arrangements involving the sales of radio frequency solutions in the Network Solutions segment, digital signal processing hardware in the Embedded Solutions segment and noise generators and components and power meter and analyzers in the Test and Measurement segment. When the terms of a contract include the transfer of multiple products, each distinct product is identified as a separate performance obligation. Generally, satisfaction occurs when control of the promised goods is transferred to the customer in exchange for consideration in an amount for which we expect to be entitled. Generally, control is transferred when legal title of the asset moves from the Company to the customer. We sell our products to a customer based on a purchase order, and the shipping terms per each individual order are primarily used to satisfy the single performance obligation. However, in order to determine control has transferred to the customer, the Company also considers: ● when the Company has a present right to payment for the asset ● when the Company has transferred physical possession of the asset to the customer ● when the customer has the significant risks and rewards of ownership of the asset ● when the customer has accepted the asset Software Arrangements involving licenses of software in the Embedded Solutions segment may involve multiple performance obligations, most notably subsequent releases of the software. The Company has concluded that each software release in a multiple deliverable arrangement in the Embedded Solutions segment is a distinct performance obligation and, accordingly, transaction price is allocated to each release when the customer obtains control of the software. Performance obligations that are not distinct at contract inception are combined. Specifically, with the Company’s sales of software, contracts that include customization may result in the combination of the customization services with the license as one distinct performance obligation and recognized over time. The duration of these performance obligations are typically one year or less. Services Arrangements involving calibration and repair services in the Company’s Test and Measurement segment are generally considered a single performance obligation and are recognized as the services are rendered. Shipping and Handling Shipping and handling activities performed after the customer obtains control are accounted for as fulfillment activities and recognized as cost of revenues. Significant Judgments For the Company’s more complex software and services arrangements significant judgment is required in determining whether licenses and services are distinct performance obligations that should be accounted for separately, or, are not distinct, and thus accounted for together. Further, in cases where we determine that performance obligations should be accounted for separately, judgment is required to determine the standalone selling price for each distinct performance obligation. Certain of the Company shipments include a limited return right. In accordance with Topic 606 the Company recognizes revenue net of expected returns. Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers and these timing differences result in contract assets or contract liabilities (deferred revenue) on the Company’s Consolidated Balance Sheet. The Company records a contract asset when revenue is recognized prior to invoicing, or deferred revenue when revenue is recognized subsequent to invoicing. Contract assets are recorded in prepaid expenses and other current assets and are $0.1 million and $0.3 million as of December 31, 2019 and 2018, respectively. Deferred revenue is $42,000 and $0.1 million as of December 31, 2019 and 2018, respectively. Disaggregated Revenue We disaggregate our revenue from contracts with customers by product family and geographic location for each of our segments as we believe it best depicts how the nature, timing and uncertainty of our revenue and cash flows are affected by economic factors.

Debt Disclosure [Abstract]
Debt	NOTE 4 - DEBT Debt consists of the following (in thousands): December 31, 2019 Revolver at LIBOR Plus Margin $ 2,354 Term Loan at LIBOR Plus Margin 342 Total Debt 2,696 Debt Maturing within one year (2,696 ) Non-current portion of long term debt $ - The Company entered into a Credit Facility with Bank of America, N.A. (the “Lender”) on February 16, 2017 (the “Credit Facility”), which provided for a term loan in the aggregate principal amount of $0.8 million (the “Term Loan”) and an asset based revolving loan (the “Revolver”), which is subject to a Borrowing Base Calculation (as defined in the Credit Facility) of up to a maximum availability of $9.0 million (“Revolver Commitment Amount”). The borrowing base is calculated as 85% of eligible accounts receivable and inventory, as defined, subject to certain caps and limits. The borrowing base is calculated on a monthly basis. The proceeds of the Term Loan and Revolver were used to finance the acquisition of CommAgility. In connection with the issuance of the Credit Facility, the Company paid lender and legal fees of $0.2 million which were primarily related to the Revolver and are capitalized and presented as other current and non-current assets in the Consolidated Balance Sheets. These costs are recognized as additional interest expense over the term of the related debt instrument using the straight line method which approximates the effective interest method. The Company must repay the Term Loan in installments of $38,000 per quarter due on the first day of each fiscal quarter beginning April 1, 2017 and continuing until the Term Loan maturity date, on which the remaining balance is due in a final installment. The future principal payments under the Term Loan are $0.3 million in 2020. The Term Loan and Revolver were both scheduled to mature on November 16, 2019. On February 26, 2019 the Company entered into Amendment No. 3 to the Credit Facility which extends the termination date of the Revolver from November 16, 2019 to March 31, 2020 (See Note 15). On November 8, 2019 the Company entered into Amendment No. 4 to the Credit Facility which extends the maturity date of the Term Loan to coincide with the extension of the Revolver at March 31, 2020, and then on February 7, 2020, entered into Amendment No. 5 (see Note 15 Subsequent Event), which, inter alia, extended the maturity date of the Revolver to March 31, 2023. The Term Loan and Revolver bear interest at the LIBOR rate plus a margin. The margin on the outstanding balance of the Company’s Term Loan and Revolver were fixed at 3.50% and 3.00% per annum, respectively, through September 30, 2017. Thereafter, the margins were subject to increase or decrease by Lender on the first day of each of the Borrowers’ fiscal quarters based upon the Fixed Charge Coverage Ratio (as defined in the Credit Facility) as of the most recently ended fiscal quarter falling into three levels. If the Company’s Fixed Charge Coverage Ratio is greater than or equal to 1.25 to 1.00, a margin of 3.25% and 2.75%, respectively, is added to LIBOR rate with a step up to 3.50% and 3.00%, respectively, if the ratio is greater than or equal 1.00 to 1.00 but less than 1.25 to 1.00 and another step up to 3.75% and 3.25%, respectively, if the ratio is less than 1.00 to 1.00. The Company is also required to pay a commitment fee on the unused commitments under the Revolver at a rate equal to 0.50% per annum and early termination fee of (a) 2% of the Revolver Commitment Amount and Term Loan if termination occurs before the first anniversary of the Credit Facility or (b) 1% of the Revolver Commitment Amount and Term Loan if termination occurs after the first anniversary of the Credit Facility but before the second anniversary of the Credit Facility. The Company’s interest rate plus margin as of December 31, 2019 was 4.63% and 5.13% for the Revolver and Term Loan, respectively. The Company’s interest rate plus margin as of December 31, 2018 was 5.38% and 5.88% for the Revolver and Term Loan, respectively. The Credit Facility is secured by liens on substantially all of the Company’s and its domestic subsidiaries’ assets including a pledge of 66 1/3% of the equity interests in the Company’s Foreign Subsidiaries (as defined in the Credit Facility). The Credit Facility contains customary affirmative and negative covenants for a transaction of this type, including, among others, the provision of annual, quarterly and monthly financial statements and compliance certificates, maintenance of property, insurance, compliance with laws and environmental matters, restrictions on incurrence of indebtedness, granting of liens, making investments and acquisitions, paying dividends, entering into affiliate transactions and asset sales. Events of default under the Credit Facility include but are not limited to: failure to pay obligations when due, breach or failure of any covenant, insolvency or bankruptcy, materially misleading representations or warranties, occurrence of a Change in Control (as defined) or occurrence of conditions that have a Material Adverse Effect (as defined). As of December 31, 2019, and the date hereof, the Company is in compliance with the covenants of the Credit Facility.

Accounting for Stock Based Compensation	NOTE 9 - ACCOUNTING FOR STOCK BASED COMPENSATION The Company follows the provisions of ASC 718. The Company’s results for the years ended December 31, 2019 and December 31, 2018 include stock based compensation expense totaling $0.6 million and $0.7 million, respectively. Such amounts have been included in the consolidated statement of operations and comprehensive loss within operating expenses. Incentive Compensation Plan In 2012, the Company’s Board of Directors and shareholders approved the 2012 Incentive Compensation Plan (the “Initial 2012 Plan”), which provides for the grant of equity, including restricted stock awards, restricted stock units, non-qualified stock options and incentive stock options in compliance with the Internal Revenue Code of 1986, as amended, to employees, officers, directors, consultants and advisors of the Company who are expected to contribute to the Company’s future growth and success. When originally approved, the Initial 2012 Plan provided for the grant of awards relating to 2 million shares of common stock, plus those shares subject to awards previously issued under the Company’s 2000 Stock Option Plan that expire, are canceled or are terminated after adoption of the Initial 2012 Plan without having been exercised in full and would have been available for subsequent grants under the 2000 Stock Option Plan. In June 2014, the Company’s shareholders approved the Amended and Restated 2012 Incentive Compensation Plan (the “2012 Plan”) allowing for an additional 1.6 million shares of the Company’s common stock to be available for future grants under the 2012 Plan. The 2012 Plan provides that if awards are forfeited, expire or otherwise terminate without issuance of the shares underlying the awards, or if the award does not result in issuance of all or part of the shares underlying the award, the unissued shares are again available for awards under the 2012 Plan. As a result of certain award forfeitures and cancellations, as of December 31, 2019, there are approximately 1.7 million shares available for issuance under the 2012 Plan. All service-based (time vesting) options granted have ten-year terms from the date of grant and typically vest annually and become fully exercisable after a maximum of five years. However, vesting conditions are determined on a grant by grant basis. Performance-based options granted have ten-year terms and vest and become fully exercisable when determinable performance targets are achieved. Performance targets are approved by the Company’s compensation committee of the Board of Directors. Under the 2012 Plan, options may be granted to purchase shares of the Company’s common stock exercisable only at prices equal to or above the fair market value on the date of the grant. The following summarizes the components of share-based compensation expense for the years ending December 31 (in thousands): 2019 2018 Service Based Restricted Stock Awards $ 278 $ 172 Service Based Restricted Stock Units 245 175 Performance Based Stock Options (90 ) 50 Service Based Stock Options 151 305 $ 584 $ 702 As of December 31, 2019, $0.1 million of unrecognized compensation costs related to unvested stock options is expected to be recognized over a remaining weighted average period of 1.8 years, $0.2 million of unrecognized compensation costs related to unvested restricted shares is expected to be recognized over a remaining weighted average period of 1.6 years and $0.1 million of unrecognized compensation costs related to unvested restricted stock units is expected to be recognized over 6 months. During the twelve months ended December 31, 2019 the Company reversed $0.1 million in share based compensation expense related to 240,000 unvested stock options that were forfeited as a result of employees exiting the company. The company had no stock option or restricted share forfeitures during the twelve months ended December 31, 2018.

Each RSU represents the Company’s obligation to issue one share of the Company’s common stock subject to the RSU award agreement and 2012 Plan. The RSU’s vest on the day before the first anniversary of the grant date or, if earlier, the effective date of a separation of service due to death or disability, provided the board member has rendered continuous service to the Company as a member of the board of directors from grant date to vesting date. Once vested, the RSU will be settled by delivery of shares to the board member no later than 30 days following: 1) the third anniversary of the grant date, 2) separation from service following, or coincident with, a vesting date, or 3) a change in control.

All of the aforementioned performance-based stock options were exercisable as of December 31, 2019. The range of exercise prices of outstanding performance-based options at December 31, 2019 is $0.78 to $1.83 with a weighted average exercise price of $1.61 per share. Under the terms of the performance-based stock option agreements, the awards will fully vest and become exercisable on the date on which the Company’s Board of Directors shall have determined that specific financial performance milestones have been met, provided the employee remains in the employ of the Company at such time; provided, however, upon a Change in Control (as defined in the stock option agreements and the 2012 Plan), the stock options shall automatically vest as permitted by the 2012 Plan. As of December 31, 2019 and 2018, the Company has determined that the performance conditions on 85,000 and 285,000 options, respectively, granted in 2013 and later are probable of being achieved by the year ending 2021. The Company’s performance-based stock options granted prior to 2013 (consisting of 20,000 options) are fully amortized.

Income Taxes	NOTE 12 - INCOME TAXES The components of income tax (benefit)/expense related to net income (loss) from operations are as follows: Years Ended December 31, 2019 2018 Current: Federal $ (9 ) $ - State 45 46 Foreign (859 ) (223 ) Deferred: Federal (188 ) 389 State (233 ) (41 ) Foreign (128 ) (123 ) Total $ (1,372 ) $ 48 The following is a reconciliation of the maximum statutory federal tax rate to the Company’s effective tax relative to operations: Years Ended December 31, 2019 2018 % of % of Statutory federal income tax rate (21.0 )% 21.0 % State income tax net of federal tax benefit 0.1 137.5 Foreign rate difference 7.2 (239.7 ) Change in valuation allowance (10.6 ) (138.2 ) Permanent differences 0.9 11.8 Research and development incentive (53.1 ) (342.7 ) Global intangible low-taxed income 1.3 607.6 Other (1.6 ) (0.2 ) Total (76.8 )% 57.1 % In 2019, the difference between the statutory and effective tax rate is due primarily to research and development deductions in the United Kingdom and a reduction in the state valuation allowance. In 2018, the difference between the statutory and effective tax rate is due to global intangible low-taxed income, research and development deductions in the United Kingdom, foreign tax rate differences and a reduction in the state valuation allowance. The components of deferred income taxes are as follows: Years Ended December 31, 2019 2018 Deferred tax assets: Net operating loss carryforwards $ 11,538 $ 11,259 Inventory 397 943 Research and development credit 648 648 Stock compensation 285 138 Other 326 73 Goodwill and intangible assets (757 ) (925 ) Fixed assets (275 ) (438 ) Gross deferred tax asset 12,162 11,698 Less valuation allowance (6,652 ) (6,722 ) Net deferred tax asset $ 5,510 $ 4,976 The Company has domestic federal and state net operating loss carryforwards at December 31, 2019 of approximately $18.2 million and $44.1 million, respectively, which begin to expire in 2029. $0.6 million of the federal net operating loss carryforward has no expiration. The Company also has foreign net operating loss carryforwards at December 31, 2019 of approximately $15.0 million for German trade tax purposes, which has no expiration. The Company has domestic federal interest expense carryforward at December 31, 2019 of approximately $0.2 million which has no expiration. Realization of the Company’s deferred tax assets is dependent upon the Company generating sufficient taxable income in the appropriate tax jurisdictions in future years to obtain benefit from the reversal of net deductible temporary differences and from utilization of net operating losses. The Company’s valuation allowances of $6.7 million at December 31, 2019 and 2018 are associated with the Company’s foreign net operating loss carryforward from an inactive foreign entity, state net operating loss carryforward and a state research and development credit. The amount of deferred tax assets considered realizable is subject to adjustment in future periods if estimates of future taxable income are changed. As of December 31, 2019, management believes that it is more likely than not that the Company will fully realize the benefits of its deferred tax assets associated with its domestic federal net operating loss carryforward. The Company does not have any significant unrecognized tax positions and does not anticipate a significant increase or decrease in unrecognized tax positions within the next twelve months. The Company has elected to record taxes related to the global intangible low-taxed income as a period cost.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 13 – FAIR VALUE MEASUREMENTS Fair value is defined by ASC 820 “Fair Value Measurement” as the price that would be received upon selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: ● Level 1 - Quoted prices in active markets for identical assets and liabilities. ● Level 2 - Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. ● Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. Payment of a portion of the CommAgility purchase price was contingent on the achievement of certain financial targets for the years ending December 31, 2017 and 2018. The Company estimated the fair value of contingent consideration at acquisition date to be $0.8 million. During the twelve months ended December 31, 2018 the Company reassessed the fair value of the contingent consideration and recorded a loss in the amount of $0.6 million as a result of the improved financial results at CommAgility as compared to prior estimates. The significant inputs used in the fair value estimate included anticipated gross revenues and Adjusted EBITDA, as defined, and scenarios for the earn-out periods for which probabilities are assigned to each scenario to arrive at a single estimated outcome. The estimated outcome was then discounted based on individual risk analysis of the liability which was 15% at December 31, 2018 and was paid in March 2019. The contingent consideration liability is considered a Level 3 fair value measurement.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 14 - COMMITMENTS AND CONTINGENCIES Warranties The Company typically provides one to three year warranties on all of its products covering both parts and labor. The Company, at its option, repairs or replaces products that are defective during the warranty period if the proper preventive maintenance procedures have been followed by its customers. Legal Proceeding On June 5, 2019 Harris Corporation (“Harris”) filed a request for arbitration before the American Arbitration Association in accordance with the terms of an executed purchase order, statement of work and software license agreement (collectively referred to as “Agreements”) with CommAgility entered into in 2014. Harris claims that CommAgility breached the Agreements by offering for sale, marketing, and promoting techniques, capabilities, products and services that incorporate Work Product, as defined in the Agreements, owned by Harris. Harris claims that CommAgility has caused Harris monetary damages, the sum of which cannot be determined until such time as discovery has been conducted, but is estimated by Harris to be less than $250,000. Harris is also seeking an injunction against CommAgility’s use of the Work Product which includes rights to certain technology used for air-to-ground communications. The Company believes the claims are without merit and intends to defend all of the claims vigorously. The Company has not accrued any amounts in respect of this matter and cannot estimate the possible loss, if any, that the Company may incur with respect to it. The ultimate outcome of this matter is unknown but, in the opinion of management, we do not believe this proceeding will have a material adverse effect upon our financial condition, cash flows or future results of operations. Legal expenses incurred in connection with the arbitration from August 2019 are covered by our professional indemnity insurance policy. Risks and Uncertainties Proprietary information and know-how are important to the Company’s commercial success. There can be no assurance that others will not either develop independently the same or similar information or obtain and use proprietary information of the Company. Certain key employees have signed confidentiality and non-compete agreements regarding the Company’s proprietary information. The Company believes that its products do not infringe the proprietary rights of third parties. There can be no assurance, however, that third parties will not assert infringement claims in the future. The Company’s deferred tax asset is recorded at tax rates expected to be in existence when those assets are utilized. Should the tax rates change materially in the future the amount of deferred tax asset could be materially impacted.

Subsequent Events [Abstract]
Subsequent Events	NOTE 15 – SUBSEQUENT EVENTS Holzworth Acquisition On November 13, 2019 the Company entered into a Share Purchase Agreement with Holzworth Instrumentation Inc., a Colorado corporation (“Holzworth”), Jason Breitbarth, Joe Koebel, and Leyla Bly (collectively, the “Sellers”), and Jason Breitbarth, as the designated representative of the Sellers, as amended by a First Amendment to Share Purchase Agreement, dated January 31, 2020 (collectively, the “Share Purchase Agreement”). On February 7, 2020, the Company completed the acquisition (the “Acquisition”) of all of the outstanding shares of Holzworth, from the Sellers. The Acquisition was completed pursuant to the terms of the Share Purchase Agreement. Holzworth instruments which include signal generators and phased noise analyzers are used by government labs, the semiconductor industry, and network equipment providers, among others, in research and automated test environments. Holzworth is a complimentary business for our Test and Measurement segment with a common customer base and channel partners. Holzworth revenues for the year end fiscal 2018 were $4.0 million and for the nine months ended September 30, 2019 were $4.3 million. For the fiscal year ended December 31, 2020, the Company will report the financial results of Holzworth in our Test and Measurement segment. The aggregate purchase price for the Acquisition is a maximum of $17.0 million, consisting of payments in cash and stock, deferred purchase price payments and contingent consideration in the form of an earnout. At the closing, the Company issued a promissory note, which required the Company to pay on the next business day $0.5 million of the purchase price by issuing 347,318 shares of its common stock (the “Stock Consideration”), and $8.0 million in cash (the “Cash Consideration”), reduced by an indemnification holdback of $0.8 million and payment of certain of Sellers’ transaction expenses and indebtedness of Holzworth. The parties intend to make a 338(h)(10) election to treat the Acquisition as a purchase and sale of assets, and the Company has agreed to pay any incremental taxes of Sellers resulting from that election. The first deferred purchase price payment of $750,000 is due in three equal quarterly installments on March 31, 2020, June 30, 2020 and September 30, 2020, respectively. The second deferred purchase price payment of $750,000 is payable on March 31, 2021. Each deferred payment may be reduced as provided in the Purchase Agreement if Holzworth’s EBITDA (as defined in the Purchase Agreement) for each fiscal year ending December 31, 2019 and December 31, 2020, respectively, is less than $1.25 million. The Company may also be required to pay additional amounts in cash and stock as earnout consideration. The first earnout payment will be equal to two times the amount, if any, by which Holzworth’s EBITDA for the fiscal year ending December 31, 2020 exceeds $1.25 million. The second earnout payment will be equal to two times the amount, if any, by which Holzworth’s EBITDA for the fiscal year ending December 31, 2021 exceeds the greater of $1.25 million or Holzworth’s EBITDA for the prior fiscal year. The aggregate earnout payments, if any, cannot exceed $7.0 million. Pursuant to the Purchase Agreement the Company entered into a lock-up and voting agreement (the “Lock-up and Voting Agreement”) with each of the Sellers. Pursuant to the Lock-up and Voting Agreement, each Seller agrees to restrict the sale, assignment, transfer, encumbrance or other disposition of its portion of the Stock Consideration (the “Lock-up Shares”). For a period commencing on the closing date of the Acquisition (the “Effective Date”) and ending on the date which is 36 calendar months following the Effective Date, each Seller agrees that, without prior written consent by the Company, such Seller shall not sell, assign, transfer, encumber or otherwise dispose of the Lock-up Shares or enter into any swap, option or short sale, among other transactions. Upon the prior written consent of the Company, a Seller may transfer Lock-up Shares as a bona fide gift, by will or intestacy or to a family member or trust for the benefit of the Seller or a family member; provided In addition, each Seller, subject to certain limitations, agrees, among other things, to appear at each meeting of the shareholders of the Company and vote all of such Seller’s Lock-up Shares (a) in favor or against any proposal presented to the shareholders in the same manner that the Company’s Board of Directors (the “Board”) recommends shareholders vote on such proposal and (b) in favor of any proposal presented to the shareholders with respect to an action of the Company, which the Board has approved, but as to which the Board has not made any recommendation, including in favor of any proposal to adjourn or postpone any meeting of the Company’s shareholders if such adjournment or postponement is conducted in accordance with the terms of the Lock-up and Voting Agreement. To the extent any shares of Company common stock are issued in payment of any Earnout Consideration (as defined in the Share Purchase Agreement) in accordance with the terms of the Share Purchase Agreement, such shares shall be subject to all applicable transfer restrictions, voting and other provisions set forth in the Lock-up and Voting Agreement, with the Effective Date with respect to such shares being the date such shares were issued; provided that, to the extent the portion of the first $1.5 million of Earnout Consideration that is paid in cash represents less than 30% of such Earnout Consideration, the portion of shares of Company common stock issued as Earnout Consideration constituting the difference between the cash percentage paid and 30% of the first $1.5 of Earnout Consideration shall not be considered Lock-Up Shares. New Term Loan Facility and Amended Credit Facility In connection with the Acquisition, on February 7, 2020, the Company, as borrower, and its subsidiaries, as guarantors, and Muzinich BDC, Inc., as lender (“Muzinich”), entered into the Term Loan Facility, which provides for a term loan in the principal amount of $8.4 million (the “Initial Term Loan”). Principal payments on the Initial Term Loan are $21,000 per quarter with a balloon payment at maturity. The term loan bears interest at LIBOR (subject to a floor of 1.0%) plus a margin of 7.25%. The Term Loan Facility includes an upfront fee of 2.50% of the aggregate principal amount of the Initial Term Loan. The Company may prepay the Initial Term Loan at any time. Prepayments made prior to (a) February 7, 2022 are subject to a prepayment premium in the amount of 2.0% of the prepaid principal amount and (b) February 7, 2023 are subject to a prepayment premium in the amount of 1.0% of the prepaid principal amount. The Company is required to make prepayments of the Initial Term Loan with the proceeds of certain asset dispositions, insurance recoveries and extraordinary receipts, subject to specified reinvestment rights. The Company is also required to make prepayments of the Initial Term Loan upon the issuance of certain indebtedness and to make an annual prepayment based upon the Company’s excess cash flow. Mandatory prepayments with asset sale, insurance or condemnation proceeds and excess cash flow may be made without penalty. Mandatory prepayments with the proceeds of indebtedness are subject to the same prepayment penalties as are applicable to voluntary prepayments. The maturity date for the Initial Term Loan is February 7, 2025. The Term Loan Facility provides for an additional $11.6 term loan (the “Second Term Loan”) to be used for a second unannounced acquisition for which the Company has entered into a confidential, non-binding letter-of-intent (the “Additional Acquisition”). There can be no assurance that the Additional Acquisition will be completed. In the event the Additional Acquisition is completed, the Second Term Loan will be made available to the Company on the same terms and conditions as the Initial Term Loan, including interest rate, amortization schedule and financial covenants, subject to the payment of an additional upfront fee and satisfaction of customary conditions to funding. The Term Loan Facility is secured by liens on substantially all of the Company’s and its subsidiaries’ assets including a pledge of the equity interests in the Company’s subsidiaries. The Term Loan Facility contains customary affirmative and negative covenants for a transaction of this type, including, among others, the provision of annual, quarterly and monthly financial statements and compliance certificates, maintenance of property, insurance, compliance with laws and environmental matters, restrictions on incurrence of indebtedness, granting of liens, making investments and acquisitions, paying dividends, entering into affiliate transactions and asset sales. In addition, the Company must maintain certain financial covenants typical for this type of arrangement, including a consolidated leverage ratio, a consolidated fixed charge coverage ratio and minimum liquidity of its foreign subsidiaries. The consolidated leverage ratio is defined as the ratio of total consolidated indebtedness, as defined, to consolidated EBITDA, as defined. The required leverage ratio starts at 4.75 to 1.0 for the twelve month periods ended March 31, 2020 and June 30, 2020, and decrease in various increments to 3.75 to 1.0 for the twelve months ended December 31, 2020, 2.75 to 1.0 for the twelve months ended December 31, 2021 and 2.0 to 1.0 for the twelve months ended December 31, 2022 and thereafter. The consolidated fixed charge coverage ratio is the ratio of consolidated EBITDA, as defined, less consolidated capital expenditures and cash income taxes paid to consolidated fixed charges, as defined, calculated on a twelve month basis. The consolidated fixed charge coverage ratio for the twelve month periods ended March 31, 2020, June 30 2020 and September 30, 2020 must be 1.35 to 1 and increases in various increments on a quarterly basis to 1.5 to 1.0 for the twelve month period ended December 31, 2020 and 2021, and to 1.75 to 1.0 for the twelve months ending December 31, 2022 and thereafter. Lastly, the Company must maintain minimum liquidity, defined as cash and availability under the UK borrowing base, as defined, of $1.0 million over any trailing four-week period until such time as the foreign subsidiary has positive EBITDA, as defined, for three consecutive quarters and the Holzworth deferred purchase price has been paid in full. The Term Loan Facility also provides for a number of events of default, including, among others, nonpayment, bankruptcy, inaccuracy of representations and warranties, breach of covenant, change in control, entry of final judgement or order, breach of material contracts, and as long as the Company’s consolidated leverage ratio is greater than 1.0 to 1.0 (as calculated in accordance with the terms of the Term Loan Facility), the cessation of service of any two of Tim Whelan, Michael Kandell or Daniel Monopoli as Chief Executive Officer, Chief Financial Officer or Chief Technology Officer, respectively, of the Borrower without a satisfactory replacement within 60 days. Any exercise of remedies by Muzinich is subject to compliance with the intercreditor agreement entered into at the closing of the Term Loan Facility among the Company, Muzinich and Bank of America, N.A., as lender under the Credit Facility referenced below. Also in connection with the Acquisition, on February 7, 2020, the Company and certain of its subsidiaries (the “Borrowers”), and Bank of America, N.A. entered into Amendment No. 5 (the “Amendment”) to the Credit Facility. By entering into the Amendment, Holzworth, together with CommAgility Limited, became borrowers under the Credit Facility. The obligations of the Borrowers under the Credit Facility are guaranteed by Wireless Telecom Group, Ltd., CommAgility Limited and Wireless Telecom Group, Ltd. are both wholly owned subsidiaries of the Company. The Amendment (a) effected certain modifications to the Credit Facility to accommodate the Acquisition, the Company’s incurrence of the Initial Term Loan and the granting of the related liens and security interests, (b) subject to the satisfaction of certain conditions precedent, made available to CommAgility an asset based revolving loan, subject to a borrowing base calculation applicable to CommAgility’s assets, of up to a maximum availability of $5.0 million (the “UK Revolver Commitment”), (c) reduced the interest rate margin applicable to revolving loans made under the Credit Facility from a range of 2.75% to 3.25% to a range of 2.00% to 2.50%, based on the Borrowers’ Fixed Charge Coverage Ratio (as defined in the Credit Facility) of the most recently completed fiscal quarter, (d) extended the Revolver Termination Date to March 31, 2023 and (e) conditioned the Borrowers’ ability to make certain debt payments under the Term Loan Facility (described above) upon compliance with a liquidity test. In all other material respects, the Credit Facility remains unchanged. Effectiveness of the Amendment was conditioned upon, among other things, the prepayment of the remaining principal balance (approximately $0.3 million) of the $0.8 million term loan made available under the Credit Facility and the payment of a closing fee in the amount of $25,000. The Borrowers satisfied all such conditions on February 7, 2020. Issuance of Stock Warrants Pursuant to the Term Loan Facility, the Company issued a Warrant, dated February 7, 2020 (the “Warrant”), to Muzinich. Under the Warrant, Muzinich has the right to purchase 266,167 shares of common stock of the Company at an exercise price of $1.3923 per share (an aggregate value of approximately $370,588), based on a 90-day volume weighted average price for shares of stock of the Company (the “Warrant Stock”). The Warrant is exercisable for an indefinite period from the date of the Warrant and may be exercised on a cashless basis. The number of shares of common stock deliverable upon exercise of the Warrant is subject to adjustment for subdivision or consolidation of shares and other standard dilutive events. In connection with the issuance of the Warrant, the Company granted Muzinich one demand registration right and piggyback registration rights with respect to the Warrant Stock, subject to certain exceptions. If the Additional Acquisition is consummated, the Company has agreed to issue to Muzinich at the closing of the Additional Acquisition an additional Warrant for the right to purchase 367,564 shares of common stock of the Company at an exercise price of $1.3923 per share (an aggregate value of approximately $511,765), based upon a 90-day volume weighted average price for shares of stock of the Company as of February 7, 2020 (the “Additional Warrant”). The Additional Warrant will contain the same terms and conditions as the Warrant, except that Muzinich will have only one demand registration right, subject to certain exceptions, with respect to shares of common stock of the Company issued under the Warrant and the Additional Warrant.

(“Noisecom”), and its wholly owned subsidiaries including Boonton Electronics Corporation (“Boonton”), Microlab/FXR (“Microlab”), Wireless Telecommunications Ltd. and CommAgility Limited (“CommAgility”). The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. The Consolidated Financial Statements have been prepared using accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany accounts and transactions have been eliminated in consolidation. The Company presents its operations in three reportable segments: (1) Network Solutions, (2) Test and Measurement and (3) Embedded Solutions. The Network Solutions segment is comprised of the operations of Microlab. The Test and Measurement segment is comprised of the operations of Boonton and Noisecom. The Embedded Solutions segment is comprised of the operations of CommAgility.
Use of Estimates	Use of Estimates The accompanying financial statements have been prepared in accordance with U.S. GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Accordingly, actual results could differ from those estimates. The most significant estimates and assumptions include management’s analysis in support of inventory valuation, accounts receivable valuation, valuation of deferred tax assets, returns reserves, warranty accruals, intangible assets, estimated fair values of stock options and vesting periods of performance-based stock options and restricted stock.
Concentrations of Credit Risk, Purchases and Fair Value	Concentrations of Credit Risk, Purchases and Fair Value Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable. Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated to a lesser extent through collateral such as letters of credit, bank guarantees or payment terms like cash in advance. For the years ended December 31, 2019 and 2018 one customer, from the Embedded Solutions segment, accounted for 24.8% and 22.0% of the Company’s total consolidated revenues, respectively. At December 31, 2019, one customer exceeded 10% of consolidated gross accounts receivable at 12.9%. At December 31, 2018 one customer exceeded 10% of consolidated gross accounts receivable at 32.1%. For the year ended December 31, 2019, three suppliers comprised or exceeded 10% of consolidated inventory purchases at 18%, 14%, and 10% respectively. For the year ended December 31, 2018 two suppliers comprised or exceeded 10% of consolidated inventory purchases at 15% and 13%, respectively.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments purchased with maturities of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist of operating accounts.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. Estimated allowances for doubtful accounts are reviewed periodically taking into account the customer’s recent payment history, the customer’s current financial statements and other information regarding the customer’s credit worthiness. Account balances are charged off against the allowance when it is determined the receivable will not be recovered.
Inventories	Inventories Inventories are stated at the lower of cost (average cost) or net realizable value. Net realizable value is based upon an estimated average selling price reduced by estimated costs of completion, disposal and transportation. Reductions in inventory valuation are included in cost of revenues in the accompanying Consolidated Statements of Operations and Comprehensive Loss. Finished goods and work-in-process include material, labor and overhead expenses. The Company reviews inventory for excess and obsolescence based on best estimates of future demand, product lifecycle status and product development plans. The Company uses historical information along with these future estimates to reduce the inventory cost basis. Subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Inventory carrying value is net of inventory reserves of approximately $1.0 million as of December 31, 2019 and $1.9 million as of December 31, 2018. Inventories consist of (in thousands): December 31, 2019 December 31, 2018 Raw materials $ 4,023 $ 3,248 Work-in-process 406 557 Finished goods 2,896 3,079 $ 7,325 $ 6,884
Prepaid Expenses and Other Current Assets	Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets generally consist of income tax receivables, contract assets, prepaid insurance, prepaid maintenance agreements and the short term portion of debt issuance costs. The income tax receivable balance included in prepaid and other current assets was $1.1 million as of December 31, 2019 as compared to a balance of $0.8 million as of December 31, 2018.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are reflected at cost, less accumulated depreciation. Depreciation and amortization are provided on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives for the property, plant and equipment are: Machinery and computer equipment 3-8 years Furniture and fixtures 5-7 years Transportation equipment 4 years Leasehold improvements are amortized over the shorter of the remaining term of the lease or the estimated economic life of the improvement. Repairs and maintenance are charged to operations as incurred; renewals and betterments are capitalized.
Goodwill	Goodwill Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a purchase business combination. Goodwill is evaluated for impairment annually by first performing a qualitative evaluation of events and circumstances impacting the reporting unit to determine the likelihood of goodwill impairment. Based on that qualitative evaluation, if we determine it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, no further evaluation is necessary. Otherwise we perform a quantitative impairment test. As of December 31, 2019 the Company’s consolidated goodwill balance of $10.1 million is comprised of $1.4 million related to the Microlab reporting unit and $8.7 million related to the CommAgility reporting unit. The Company performed a qualitative assessment in the fourth quarter of 2019 of each reporting unit. The qualitative assessment of Microlab did not indicate any impairment of goodwill. As a result of declining future demand of the CommAgility’s signal processing hardware and the uncertainty associated with new product revenues to offset the signal processing hardware sale decline, the Company performed a quantitative impairment test of the goodwill of the CommAgility reporting unit. For goodwill impairment testing using the quantitative approach, the Company estimates the fair value of the selected reporting unit primarily through the use of a discounted cash flow model based on our best estimate of amounts and timing of future revenues and cash flows and our most recent business and strategic plans, and compares the estimated fair value to the carrying value of the reporting unit, including goodwill. If the fair value of the reporting unit exceeds the carrying value, no impairment charge is recorded. If the carrying value of the reporting unit exceeds the fair value an impairment charge is recorded to goodwill in the amount by which carrying value exceeds fair value. The discounted cash flow model requires judgmental assumptions about projected revenue growth, future operating margins, discount rates and terminal values over a multi-year period. There are inherent uncertainties related to these assumptions and management’s judgment in applying them to the analysis of goodwill impairment. While the Company believes it has made reasonable estimates and assumptions to calculate the fair value of its reporting units, it is possible a material change could occur. If actual results are not consistent with management’s estimates and assumptions, goodwill may be overstated and a charge would need to be taken against net earnings. Changes in our projections used in the discounted cash flow model could affect the estimated fair value of the Company’s reporting unit and could result in a goodwill impairment charge in a future period. In order to evaluate the sensitivity of the fair value calculations used in the quantitative goodwill impairment test, the Company applied a hypothetical 10% decrease to the fair value of the CommAgility reporting unit and compared those values to the carrying value. Based on this sensitivity analysis, the Company did not identify any goodwill impairment. Due to the many variables inherent in the estimation of a reporting unit’s fair value and the relative size of our recorded goodwill, differences in assumptions may have a material effect on the results of our impairment analysis. As of December 31, 2018 the Company’s consolidated goodwill balance of $9.8 million was comprised of $1.4 million related to the Microlab reporting unit and $8.4 million related to the CommAgility reporting unit. Management’s qualitative assessment performed in the fourth quarters of 2018 did not indicate any impairment of goodwill.
Intangible and Long-lived Assets	Intangible and Long-lived Assets Intangible assets include patents, non-competition agreements, customer relationships and trademarks. Intangible assets with finite lives are amortized using the straight-line method over the estimated economic lives of the assets, which range from three to five years. Long-lived assets, including intangible assets with finite lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss for long-lived assets that management expects to hold and use is based on the estimated fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or estimated fair value less costs to sell. The estimated useful lives of intangible and long-lived assets are based on many factors including assumptions regarding the effects of obsolescence, demand, competition and other economic factors, expectations regarding the future use of the asset, and our historical experience with similar assets. The assumptions used to determine the estimated useful lives could change due to numerous factors including product demand, market conditions, technological developments, economic conditions and competition. Intangible assets determined to have indefinite useful lives are not amortized but are tested for impairment annually and more frequently if events occur or circumstances change that indicate an asset may be impaired.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1 - Quoted prices in active markets for identical assets or liabilities. Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The carrying amounts of the Company’s financial instruments, including cash, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities. The Company’s term loan and revolving credit facility bear interest at a variable interest rate plus an applicable margin and, therefore, carrying amount approximates fair value.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of non-U.S. subsidiaries that operate in a local currency environment, where the local currency is the functional currency, are translated from foreign currencies into U.S. dollars at period-end exchange rates while income and expenses are translated at the weighted average spot rate for the periods presented. Translation gains or losses related to net assets located outside the U.S. are shown as a component of accumulated other comprehensive income in the Consolidated Statements of Changes in Shareholders’ Equity. Gains and losses resulting from foreign currency transactions, which are denominated in currencies other than the Company’s functional currency, are included in the Consolidated Statements of Operations and Comprehensive Loss. Foreign exchange transaction losses were not material in fiscal 2019 and were $0.1 million in 2018.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss) Other comprehensive income (loss) is recorded directly to a separate section of shareholders’ equity in accumulated other comprehensive income and includes unrealized gains and losses excluded from net income/(loss). These unrealized gains and losses consist of changes in foreign currency translation.
Research and Development Costs	Research and Development Costs Research and development costs are charged to operations when incurred. The amounts charged to operations for the years ended December 31, 2019 and 2018 were $5.9 million and $4.9 million, respectively.
Advertising Costs	Advertising Costs Advertising expenses are charged to operations during the year in which they are incurred and aggregated $0.1 million for the years ended December 31, 2019 and 2018.
Stock-Based Compensation	Stock-Based Compensation The Company follows the provisions of Accounting Standards Codification (“ASC”) 718, “Compensation – Stock Compensation” which requires that compensation expense be recognized, based on the fair value of the stock awards. The fair value of the stock awards is equal to the fair value of the Company’s stock on the date of grant. The fair value of options at the date of grant are estimated using the Black-Scholes option pricing model. When performance-based options are granted, the Company takes into consideration guidance under ASC 718 and SEC Staff Accounting Bulletin No. 107 (SAB 107) when determining assumptions. The expected option life is derived from assumed exercise rates based upon historical exercise patterns and represents the period of time that options granted are expected to be outstanding. The expected volatility is based upon historical volatility of our shares using daily price observations over an observation period that approximates the expected life of the options. The risk-free rate is based on the U.S. Treasury yield curve rate in effect at the time of grant for periods similar to the expected option life. The Company accounts for forfeitures when they occur. Management estimates are necessary in determining compensation expense for stock options with performance-based vesting criteria. Compensation expense for this type of stock-based award is recognized over the period from the date the performance conditions are determined to be probable of occurring through the implicit service period, which is the date the applicable conditions are expected to be met. If the performance conditions are not considered probable of being achieved, no expense is recognized until such time as the performance conditions are considered probable of being met, if ever. If the award is forfeited because the performance condition is not satisfied, previously recognized compensation cost is reversed. Management evaluates performance conditions on a quarterly basis.
Income Taxes	Income Taxes The Company records deferred taxes in accordance with ASC 740, “Accounting for Income Taxes”. This ASC requires recognition of deferred tax assets and liabilities for temporary differences between tax basis of assets and liabilities and the amounts at which they are carried in the financial statements, based upon the enacted rates in effect for the year in which the differences are expected to reverse. The Company establishes a valuation allowance when necessary to reduce deferred tax assets to the amount expected to be realized. The Company periodically assesses the value of its deferred tax asset, a majority of which has been generated by a history of net operating losses and determines the necessity for a valuation allowance. The Company evaluates which portion, if any, will more likely than not be realized by offsetting future taxable income, taking into consideration any limitations that may exist on its use of its net operating loss carry-forwards. Under ASC 740, the Company must recognize and disclose uncertain tax positions only if it is more-likely-than-not the tax position will be sustained on examination by the taxing authority, based on the technical merits of the position. The amounts recognized in the financial statements attributable to such position, if any, are recorded if there is a greater than 50% likelihood of being realized upon the ultimate resolution of the position. Based on the evaluations noted above, the Company has concluded that there are no significant uncertain tax positions requiring recognition or disclosure in its consolidated financial statements.
Earnings (Loss) Per Common Share	Earnings (Loss) Per Common Share Basic earnings (loss) per share is calculated by dividing net income (loss) available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share is calculated by dividing net income (loss) available to common shareholders by the weighted average number of common shares outstanding for the period and, when dilutive, potential shares from stock options using the treasury stock method, the weighted average number of unvested restricted shares and the weighted-average number of restricted stock units outstanding for the period. Shares from stock options are included in the diluted earnings per share calculation only when options exercise prices are lower than the average market value of the common shares for the period presented. In periods with a net loss, the basic loss per share equals the diluted loss per share as all common stock equivalents are excluded from the per share calculation because they are anti-dilutive. In accordance with ASC 260, “Earnings Per Share”, the following table reconciles basic shares outstanding to fully diluted shares outstanding. For the Years Ended December 31, 2019 2018 Weighted average common shares outstanding 21,110,632 20,858,298 Potentially dilutive equity awards 522,996 707,492 Weighted average common shares outstanding, assuming dilution 21,633,628 21,565,790 The weighted average number of options to purchase common stock not included in diluted loss per share because the effects are anti-dilutive, or the performance condition was not met in 2019 was 1,324,548. The weighted average number of options to purchase common stock not included in diluted loss per share in 2018, because the effects are anti-dilutive or the performance condition was not met, was 285,000.
Recent Accounting Pronouncements Adopted in 2019	Recent Accounting Pronouncements Adopted in 2019 In February 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) The Company adopted the requirements of the new standard effective January 1, 2019 using the modified retrospective transition method, which applies the provisions of the standard at the effective date without adjustment to the comparative periods presented. The Company adopted the following practical expedients and elected the following accounting policies related to this standard: ● Carry forward of historical lease classifications and accounting treatment; ● Short-term lease accounting policy election allowing lessees to not recognize right-of-use assets and liabilities for leases with a term of 12 months or less; and ● The option to not separate lease and non-lease components for certain equipment lease categories such as office printers and copiers. Adoption of this standard resulted in the recognition of operating lease right-of-use assets and corresponding lease liabilities of $1.9 million on the consolidated balance sheet as of January 1, 2019. The standard did not materially impact operating results or liquidity. Disclosures related to the amount, timing and uncertainty of cash flows arising from leases are included in Note 2. On June 20, 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.
