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 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, 2021 and 2020. 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, Net Property, plant and equipment are stated at cost less accumulated depreciation. 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, 10 years for building improvements and 6 to 10 years for machinery and equipment. (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, 2021. 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. (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 2021 and 2020. (h) Use of Estimates 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. (i) 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 $18 and zero for the years ended December 31, 2021 and 2020, respectively. The Company amortizes license fees over the life of the relevant contract. License agreements are carried at cost less accumulated amortization as follows: December 31, 2021 2020 License agreements $ 6,139 $ 6,084 Accumulated amortization (6,132 ) (6,074 ) $ 7 $ 10 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 $58 and $36 in the years ended December 31, 2021 and 2020, respectively. Amortization expense for license fees is projected to be approximately $7 in the year ending December 31, 2022. (j) 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, 2021 and 2020 and cumulative translation gains and losses as of December 31, 2021 and 2020 were not material to the financial statements taken as a whole. (k) Research and Development Research and development expenditures for the Company’s projects are expensed as incurred. Research and development expenses include payroll, employee benefits, stock-based compensation expense, and other headcount-related expenses associated with product development. (l) 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 (m) 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. (n) 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. (o) Net Earnings oss) Per Share Net earnings (loss) per share is calculated in accordance with Accounting Standards Codification ( “ASC” The following table presents the computation of basic and diluted net income per share for the year ended December 31, 2021: Income Shares Per-Share Basic EPS $ 84 12,151 $ 0.01 Effect of dilutive securities Convertible debt 271 2,142 Warrants 48 Options 1,109 Diluted EPS $ 355 15,450 $ 0.02 The diluted share base excludes the following potential common shares due to their antidilutive effect for the years ended December 31, 2021 and 2020: December 31, 2021 2020 Stock options 712 2,848 Warrants - 737 Convertible debt - 1,337 712 4,922 (p) Other Comprehensive loss Comprehensive loss is a measure of income which includes both net loss and other comprehensive loss. Other comprehensive 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. (q) Leases The Company accounts for leases under FASB ASU No. 2016-02, Leases Topic 842 (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, except as disclosed in the financial statements. (s) Adoption of Recent Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes Topic 740 (t) Going Concern and COVID-19 Our business has been materially and adversely affected by the outbreak of the Coronavirus or COVID-19. COVID-19, which has been declared by the World Health Organization to be a “pandemic,” has spread to many countries, including the United States, and is impacting domestic and worldwide economic activity. Since being declared a “pandemic”, COVID-19 interfered with our ability to meet with certain customers during 2020 and continued into the first half of 2021. In addition, the COVID-19 outbreak has affected the supply chain for many types of products and materials, particularly those being manufactured in China and other countries where the outbreak has resulted in significant disruptions to ongoing business activities. Beginning in the second quarter of 2021 and continuing into the first quarter of 2022, we experienced a material disruption in our supply chain as it relates to the procurement of certain sole source and other multiple source components utilized in a material portion of several product lines. There are frequent developments regarding the COVID-19 outbreak that may impact our customers, employees and business partners. As a result, it is not possible at this time to estimate the duration or the scope of the impact COVID-19 could have on the Company’s business. The Company has experienced and is continuing to experience a significant reduction in sales as a result of its inability to procure parts necessary to manufacture products due to the supply chain issues related to the COVID-19 outbreak. It remains unclear when or whether our supply chain partners will resume their activities at a level where our sales will return to historical levels. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. During the year ended December 31, 2021, the Company reported reduced revenues, a loss from operations and net cash used in operating activities, in conjunction with liquidity constraints. The above factors raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments relating to the recoverability of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern. The Company’s primary sources of liquidity have been its existing cash balances, cash generated from operations, amounts available under the MidCap Facility (see Note 5 below), amounts available under the Subordinated Loan Facility (see Note 6 below) and cash generated from sales of common stock (see Note 15 below). As of December 31, 2021, the Company had approximately $2,400 outstanding under the MidCap Facility (as defined in Note 5 below) and $92 of additional availability for borrowing under the MidCap Facility. If anticipated operating results are not achieved and/or the Company is unable to obtain additional financing, it may be required to take additional measures to reduce costs in order to conserve its cash in amounts sufficient to sustain operations and meet its obligations, which measures could have a material adverse effect on the Company’s ability to achieve its intended business objectives and may be insufficient to enable the Company to continue as a going concern for at least twelve months from the date these financial statements are made available to be issued. (u) Reclassification of Prior Year Amounts Certain prior year amounts have been reclassified for consistency with the current year presentation.

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 2021 2020 Fair value of the company’s common stock on date of grant $ 1.513 $ 0.595 Expected term 6.5 years 6.5 years Risk free interest rate 1.13 % 0.44 % Dividend yield 0.00 % 0.00 % Volatility 79.0 % 79.0 % Fair value of options granted $ 1.06 $ 0.41 The following table summarizes total stock-based compensation costs recognized for the years ended December 31, 2021 and 2020: Years ended 2021 2020 Cost of goods sold $ 42 $ 40 Selling expenses 77 40 General and administrative 343 227 Research and development 100 97 Total $ 562 $ 404 The following table summarizes information about stock-based awards outstanding for the year ended December 31, 2021: Plan Stock Options 2016 Employee Plan 1,974 2016 Director Plan 649 Other 500 2005 Employee Plan 865 2005 Director Plan 261 4,249 Stock-based awards available for grant as of December 31, 2021 648 Stock options award activity for the year ended December 31, 2021 is as follows: Number of Weighted- Weighted- Aggregate Intrinsic Outstanding at January 1, 2021 3,998 $ 0.86 Options granted 616 1.44 Options exercised (99 ) 0.89 Options forfeited (54 ) 1.10 Options expired (212 ) 1.61 Outstanding at December 31, 2021 4,249 $ 0.90 5.2 $ 55 Exercisable at December 31, 2021 2,970 $ 0.85 5.3 $ 18 During the year ended December 31, 2021, the Company granted options under the 2016 Employee Plan and the 2016 Director Plan to purchase 616 shares of common stock to its employees and directors.

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, 2021, 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 2021 and no liabilities for uncertain tax positions as of December 31, 2021. 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, 2021 and 2020. 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, 2018 or tax years beginning with the year ended December 31,2003 as the Company utilizes net operating losses.

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, Net	(e) Property, Plant and Equipment, Net Property, plant and equipment are stated at cost less accumulated depreciation. 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, 10 years for building improvements and 6 to 10 years for machinery and equipment.
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, 2021. 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.
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 2021 and 2020.
Use of Estimates	(h) Use of Estimates 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.
Royalty and License Expense	(i) 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 $18 and zero for the years ended December 31, 2021 and 2020, respectively. The Company amortizes license fees over the life of the relevant contract. License agreements are carried at cost less accumulated amortization as follows: December 31, 2021 2020 License agreements $ 6,139 $ 6,084 Accumulated amortization (6,132 ) (6,074 ) $ 7 $ 10 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 $58 and $36 in the years ended December 31, 2021 and 2020, respectively. Amortization expense for license fees is projected to be approximately $7 in the year ending December 31, 2022.
Foreign Exchange	(j) 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, 2021 and 2020 and cumulative translation gains and losses as of December 31, 2021 and 2020 were not material to the financial statements taken as a whole.
Research and Development	(k) Research and Development Research and development expenditures for the Company’s projects are expensed as incurred. Research and development expenses include payroll, employee benefits, stock-based compensation expense, and other headcount-related expenses associated with product development.
Revenue Recognition	(l) 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	(m) 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.
Income Taxes	(n) 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.
Net Earnings (loss) Per Share	(o) Net Earnings oss) Per Share Net earnings (loss) per share is calculated in accordance with Accounting Standards Codification ( “ASC” The following table presents the computation of basic and diluted net income per share for the year ended December 31, 2021: Income Shares Per-Share Basic EPS $ 84 12,151 $ 0.01 Effect of dilutive securities Convertible debt 271 2,142 Warrants 48 Options 1,109 Diluted EPS $ 355 15,450 $ 0.02 The diluted share base excludes the following potential common shares due to their antidilutive effect for the years ended December 31, 2021 and 2020: December 31, 2021 2020 Stock options 712 2,848 Warrants - 737 Convertible debt - 1,337 712 4,922
Other Comprehensive loss	(p) Other Comprehensive loss Comprehensive loss is a measure of income which includes both net loss and other comprehensive loss. Other comprehensive 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.
Leases	(q) Leases The Company accounts for leases under FASB ASU No. 2016-02, Leases Topic 842
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, except as disclosed in the financial statements.
Adoption of Recent Accounting Pronouncements	(s) Adoption of Recent Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes Topic 740
Going Concern and COVID-19	(t) Going Concern and COVID-19 Our business has been materially and adversely affected by the outbreak of the Coronavirus or COVID-19. COVID-19, which has been declared by the World Health Organization to be a “pandemic,” has spread to many countries, including the United States, and is impacting domestic and worldwide economic activity. Since being declared a “pandemic”, COVID-19 interfered with our ability to meet with certain customers during 2020 and continued into the first half of 2021. In addition, the COVID-19 outbreak has affected the supply chain for many types of products and materials, particularly those being manufactured in China and other countries where the outbreak has resulted in significant disruptions to ongoing business activities. Beginning in the second quarter of 2021 and continuing into the first quarter of 2022, we experienced a material disruption in our supply chain as it relates to the procurement of certain sole source and other multiple source components utilized in a material portion of several product lines. There are frequent developments regarding the COVID-19 outbreak that may impact our customers, employees and business partners. As a result, it is not possible at this time to estimate the duration or the scope of the impact COVID-19 could have on the Company’s business. The Company has experienced and is continuing to experience a significant reduction in sales as a result of its inability to procure parts necessary to manufacture products due to the supply chain issues related to the COVID-19 outbreak. It remains unclear when or whether our supply chain partners will resume their activities at a level where our sales will return to historical levels. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. During the year ended December 31, 2021, the Company reported reduced revenues, a loss from operations and net cash used in operating activities, in conjunction with liquidity constraints. The above factors raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments relating to the recoverability of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern. The Company’s primary sources of liquidity have been its existing cash balances, cash generated from operations, amounts available under the MidCap Facility (see Note 5 below), amounts available under the Subordinated Loan Facility (see Note 6 below) and cash generated from sales of common stock (see Note 15 below). As of December 31, 2021, the Company had approximately $2,400 outstanding under the MidCap Facility (as defined in Note 5 below) and $92 of additional availability for borrowing under the MidCap Facility. If anticipated operating results are not achieved and/or the Company is unable to obtain additional financing, it may be required to take additional measures to reduce costs in order to conserve its cash in amounts sufficient to sustain operations and meet its obligations, which measures could have a material adverse effect on the Company’s ability to achieve its intended business objectives and may be insufficient to enable the Company to continue as a going concern for at least twelve months from the date these financial statements are made available to be issued.
Reclassification of Prior Year Amounts	(u) Reclassification of Prior Year Amounts Certain prior year amounts have been reclassified for consistency with the current year presentation.

Term loan, description					the Initial Lenders agreed to provide the Company with a Tranche A term loan facility of $800 of which $600 was advanced to the Company on April 8, 2020, $100 was advanced to the Company on April 17, 2020 and $100 was advanced to the Company on January 12, 2021. The Initial Lenders participating in the Tranche A term loan facility have the option of converting the principal balance of the loan held by each of them, in whole (unless otherwise agreed by the Company), into shares of the Company’s common stock at a conversion price equal to the volume weighted average price of the common stock as reported by the NYSE American, during the five trading days preceding April 8, 2020 (the “Tranche A Conversion Price”) which was calculated at $0.593.
Subordinated convertible loan and security agreement, description							the Company entered into the Third Amendment to Senior Subordinated Convertible Loan and Security Agreement and Joinder (the “LSA Third Amendment”) with the Tranche A Parties, the Tranche B Parties (that had not previously converted the loans attributable to each of them into shares of common stock), the Agent and certain other investors (the “Tranche C Parties”). Pursuant to the LSA Third Amendment, the parties agreed to increase the aggregate loan limit from $1,500 to $1,600 and the Tranche C Parties agreed to provide the Company with a commitment for a $600 term loan facility, all of which was advanced to the Company on January 29, 2021 (the “Tranche C Loans”). As is the case with the loans provided by the Tranche A Parties and Tranche B Parties, interest on the Tranche C Loans accrues at 12% per annum and is payable monthly in-kind, by the automatic increase of the principal amount of the loans on each monthly interest payment date, by the amount of the accrued interest payable at that time. The Company, at its option, may pay any interest due on the Tranche C Loans in cash on any interest payment date in lieu of PIK Interest. The Tranche C Parties also have the option, following the stockholder approval described in the next sentence, of converting the accreted principal balance of the Tranche C Loans attributable to each of them into shares of the Company’s common stock at a conversion price of $1.00.
