Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), have been condensed or omitted pursuant to those rules and regulations. We believe that the disclosures made are adequate to make the information presented not misleading to the reader. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations and cash flows with respect to the audited consolidated financial statements have been included. These audited consolidated financial statements include the accounts of Pioneer and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Liquidity The accompanying financial statements have been prepared on a basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As shown in the accompanying financial statements as of the year ended December 31, 2021, the Company had $ 9.9 18.6 On June 1, 2021 0.12 June 22, 2021 July 7, 2021 0.12 0.001 1 On October 20, 2020, we entered into an At The Market Sale Agreement with H.C.

The following table provides a reconciliation of cash and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the audited consolidated statement of cash flows: December 31, 2021 2020 Cash $ 9,924 $ 7,567 Restricted cash 1,775 — Total cash and restricted cash as shown in the statement of cash flows $ 11,699 $ 7,567 COVID-19 On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus originating in Wuhan, China and the risks to the international community as the virus spreads globally beyond its point of origin. In March 2020, the WHO classified the COVID-19 outbreak as a pandemic (the “COVID-19 pandemic”), based on the rapid increase in exposure globally. The full impact of the COVID-19 pandemic continues to evolve as the date of this report. As such, it is uncertain as to the full magnitude that the pandemic will have on the Company’s financial condition, liquidity, and future results of operations. During the year ended December 31, 2021, the Company experienced an impact to productivity as a result of following social distancing guidelines and practicing personal protective measures. Notwithstanding, the Company has been able to operate substantially at capacity during the COVID-19 pandemic. Management is actively monitoring the global situation on its financial condition, liquidity, operations, suppliers, industry, and workforce. Given the daily evolution of the COVID-19 pandemic and the global responses to contain its spread, the Company is not able to estimate the full effects of the COVID-19 pandemic at this time, however, if the pandemic continues, it may continue to have an adverse effect on the Company’s results of operations, financial condition, or liquidity. On March 27, 2020, then President Trump signed into law the “Coronavirus Aid, Relief, and Economic Security (CARES) Act” (the “CARES Act”) The CARES Act, among other things, appropriates funds for the SBA Paycheck Protection Program loans that are forgivable in certain situations to promote continued employment. On April 13, 2020, after having determined that it met the qualifications for this loan program due to the impact that COVID-19 would have on our financial condition, results of operations, and/or liquidity and applying for relief, the Company received a loan under the SBA Paycheck Protection Program (the “PPP Loan”) in the amount of $ 1.4 million Under the terms of the PPP Loan, the Company was eligible for full or partial loan forgiveness. During the first quarter of 2021, the Company received full forgiveness of the PPP Loan and recognized a $ 1.4 million Rounding All dollar amounts (except share and per share data, and with respect to Item 11, Agreements with Executive Officers) presented are stated in thousands of dollars, unless otherwise noted. Amounts may not foot due to rounding.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES General The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in accordance with U.S. GAAP 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 and the reported amounts of revenues and expenses during the reporting period. The financial statements include estimates based on currently available information and management’s judgment as to the outcome of future conditions and circumstances. Significant estimates in these financial statements include allowance for doubtful accounts receivable, inventory provision, useful lives and impairment of long-lived assets and income tax provision. Changes in the status of certain facts or circumstances could result in material changes to the estimates used in the preparation of the financial statements and actual results could differ from the estimates and assumptions. Revenue Recognition Revenue is recognized when (1) a contract with a customer exists, (2) performance obligations promised in a contract are identified based on the products or services that will be transferred to the customer, (3) the transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer, (4) the transaction price is allocated to the performance obligations in the contract and (5) the Company satisfies performance obligations. The Company satisfies performance obligations either over time or at a point in time. Revenue is recognized at the time the related performance obligation is satisfied by transferring a promised product or service to a customer. Revenue from the sale of our products is predominantly recognized at a point in time. Revenues are recognized at the point in time that the customer obtains control of the good which is when it has taken title to the products and has assumed the risks and rewards of ownership specified in the purchase order or sales agreement. Certain sales of highly customized large equipment are recognized over time when such equipment has no alternative use and the Company has an enforceable right to payment for performance completed to date. Revenue for such agreements is recognized under the input method based on cost incurred relative to the estimated cost expected to be consumed to complete the project. Service revenues include maintenance contracts that are recognized over time based on the contract term and repair services which are recognized as services are delivered. Cost of Goods Sold Cost of goods sold for the T&D Solutions and Critical Power segments primarily includes charges for materials, direct labor and related benefits, freight (inbound and outbound), direct supplies and tools, purchasing and receiving costs, inspection costs, internal transfer costs, warehousing costs and utilities related to production facilities and, where appropriate, an allocation of overhead. Cost of goods sold also includes indirect labor and infrastructure cost related to the provision of field services. Financial Instruments The Company’s financial instruments consist primarily of cash, restricted cash, receivables, payables and debt instruments. The carrying values of these financial instruments approximate their respective fair values as they are either short-term in nature or carry interest rates which are periodically adjusted to market rates. Unless otherwise indicated, the carrying value of these financial instruments approximates their fair market value. Concentrations The Company manages its accounts receivable credit risk by performing credit evaluations and monitoring amounts due from the Company’s customers. The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows: At December 31, 2021 and 2020, two customers represented approximately 43 42 For the year ended December 31, 2021, two customers represented approximately 41 34 Cash and Cash Equivalents Cash and cash equivalents comprise cash on hand, demand deposits and investments with an original maturity at the date of purchase of three months or less. Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash deposits. Accounts at each institution are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $ 250 9.7 million 7.3 million Restricted Cash Restricted Cash consists of a cash collateral security agreement with a commercial bank which required the Company to pledge cash collateral as security for all unpaid reimbursement obligations owing to the commercial bank for an irrevocable standby letter of credit. Accounts Receivable The Company accounts for trade receivables at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. The Company writes off trade receivables when they are deemed uncollectible. The Company records recoveries of trade receivables previously written off when it receives them. Management considers the Company’s allowance for doubtful accounts, which was $ 140 69 Long-Lived Assets Depreciation and amortization for property, plant and equipment, and finite life intangible assets, is computed and included in cost of goods sold and in selling and administrative expense, as appropriate. Long-lived assets, consisting primarily of property, plant and equipment, are stated at cost less accumulated depreciation. Property, plant and equipment are depreciated using the straight line method, based on the estimated useful lives of the assets (buildings - 25 5 15 3 5 5 7 Historically, finite life intangible assets have consisted primarily of customer relationships in multiple categories that are specific to the businesses acquired and for which estimated useful lives were determined based on actual historical customer attrition rates. These finite life intangible assets were amortized by the Company over periods ranging from four to ten years. Long-lived assets and finite life intangible assets are reviewed for impairment whenever events or circumstances have occurred that indicate the remaining useful life of the asset may warrant revision or that the remaining balance of the asset may not be recoverable. Upon indications of impairment, or in the normal course of annual testing, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The measurement of possible impairment is generally estimated by the ability to recover the balance of an asset group from its expected future operating cash flows on an undiscounted basis. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value thereof. Determining asset groups and underlying cash flows requires the use of significant judgment. Income Taxes The Company accounts for income taxes under the asset and liability method, based on the income tax laws and rates in the countries in which operations are conducted and income is earned. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Developing the provision for income taxes requires significant judgment and expertise in federal, international and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and, if necessary, any valuation allowances that may be required for deferred tax assets. The Company records a valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized. The Company believes that the deferred asset, net recorded as of December 31, 2021 and 2020 is realizable through future reversals of existing taxable temporary differences. If the Company was to subsequently determine that it would be able to realize deferred tax assets in the future in excess of its net recorded amount, an adjustment to deferred tax assets would increase net income for the period in which such determination was made. The Company will continue to assess the adequacy of the valuation allowance on a quarterly basis. The Company’s tax filings are subject to audit by various taxing authorities. The objective of accounting for income taxes is to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences or events that have been recognized in the Company’s financial statements or tax returns. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position (see “Unrecognized Tax Benefits” below). Income tax related interest and penalties are grouped with interest expense on the consolidated statement of operations. Unrecognized Tax Benefits The Company accounts for unrecognized tax benefits in accordance with FASB ASC “Income Taxes” (“ASC 740”). ASC 740 prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements and provides guidance on de-recognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. ASC 740 contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon ultimate settlement with a taxing authority, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Additionally, ASC 740 requires the Company to accrue interest and related penalties, if applicable, on all tax positions for which reserves have been established consistent with jurisdictional tax laws. The Company’s policy is to recognize interest and penalties related to income tax matters as interest expense. See Note 14 - Income Taxes. Share-Based Payments The Company accounts for share based payments in accordance with the provisions of FASB ASC 718 “Compensation – Stock Compensation” and accordingly recognizes in its financial statements share based payments at their fair value. In addition, it recognizes in the financial statements an expense based on the grant date fair value of stock options granted to employees and directors. The expense is recognized on a straight line basis over the expected option life while taking into account the vesting period and the offsetting credit is recorded in additional paid-in capital. Upon exercise of options, the consideration paid together with the amount previously recorded as additional paid-in capital is recognized as capital stock. The Company estimates its forfeiture rate in order to determine its compensation expense arising from stock based awards. The Company uses the Black-Scholes Merton option pricing model to determine the fair value of the options. Non-employee members of the Board of Directors are deemed to be employees for the purposes of recognizing share-based compensation expense. Inventories Inventories are stated at the lower of cost or net realizable value using weighted average method and include the cost of materials, labor and manufacturing overhead. The Company uses estimates in determining the level of reserves required to state inventory at the lower of cost or market. The Company estimates are based on market activity levels, production requirements, the physical condition of products and technological innovation. Changes in any of these factors may result in adjustments to the carrying value of inventory. See Note 6 - Inventories. Income (Loss) Per Share Basic income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common and common equivalent shares outstanding during the period. (See Note 16 - Basic and Diluted Net Loss Per Share). Recent Accounting Pronouncements There have been no recent accounting pronouncements not yet adopted by the Company which would have a material impact on the Company’s financial statements.

Revenue from Contract with Customer [Abstract]
REVENUES	4. REVENUES Nature of our products and services Our principal products and services include electric power systems, distributed energy resources, used and new power generation equipment and mobile electric vehicle (“EV”) charging solutions. Products Our T&D Solutions business provides electric power systems, including e-Bloc, and distributed energy resources that help customers effectively and efficiently protect, control, transfer, monitor and manage their electric energy requirements Our Critical Power business provides customers with our suite of mobile e-Boost electric vehicle charging solutions and new and refurbished power generation equipment. Services Power generation systems represent considerable investments that require proper maintenance and service in order to operate reliably during a time of emergency. Our power maintenance programs provide preventative maintenance, repair and support service for our customers’ power generation systems. Our principal source of revenue is derived from sales of products and fees for services. We measure revenue based upon the consideration specified in the customer arrangement, and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as, the customer receives the benefit of the performance obligation. Customers typically receive the benefit of our products when the risk of loss or control for the product transfers to the customer and for services as they are performed. Under ASC 606, revenue is recognized when a customer obtains control of promised products or services in an amount that reflects the consideration we expect to receive in exchange for those products or services. To achieve this core principal, the Company applies the following five steps: 1) Identify the contract with a customer A contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the products or services to be transferred and identifies the payment terms related to these products or services, (ii) the contract has commercial substance and, (iii) the Company determines that collection of substantially all consideration for products or services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. The Company applies judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the products or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the products or services is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised products or services, the Company must apply judgment to determine whether promised products or services are capable of being distinct and distinct in the context of the contract. If these criteria are not met the promised products or services are accounted for as a combined performance obligation. 3) Determine the transaction price The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer. The customer payments are generally due in 30 days. 4) Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis or cost of the product or service. The Company determines standalone selling price based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. 5) Recognize revenue when or as the Company satisfies a performance obligation The Company satisfies performance obligations either over time or at a point in time. Revenue is recognized at the time the related performance obligation is satisfied by transferring a promised product or service to a customer. Revenue from the sale of our products is predominantly recognized at a point in time. Revenues are recognized at the point in time that the customer obtains control of the good which is when it has taken title to the products and has assumed the risks and rewards of ownership specified in the purchase order or sales agreement. Certain sales of highly customized large equipment are recognized over time when such equipment has no alternative use and the Company has an enforceable right to payment for performance completed to date. Revenue for such agreements is recognized under the input method based on cost incurred relative to the estimated cost expected to be consumed to complete the project. During the year ended December 31, 2021, the Company recognized $ 3.5 million of revenue over time and incurred costs of $ 3.1 million related to a single contract for a highly customized large equipment order. Additionally, the Company recognized $ 7.9 million of revenue at a point in time from the sale of our products during the year ended December 31, 2021. Service revenues include maintenance contracts that are recognized over time based on the contract term and repair services which are recognized as services are delivered. The Company recognized $ 6.9 million of service revenue during the year ended December 31, 2021. During the year ended December 31, 2021, the Company recognized approximately $ 714 1.4 million Return of a product requires that the buyer obtain permission in writing from the Company. When the buyer requests authorization to return material for reasons of their own, the buyer will be charged for placing the returned goods in saleable condition, restocking charges and for any outgoing and incoming transportation paid by the Company. The Company warrants title to the products, and also warrants the products on date of shipment to the buyer, to be of the kind and quality described in the contract, merchantable, and free of defects in workmanship and material. Returns and warranties during the years ended December 31, 2021 and 2020 were insignificant. The following table presents our revenues disaggregated by revenue discipline: For the Year Ended December 31, 2021 2020 Products $ 11,375 $ 11,831 Services 6,936 7,659 Total revenue $ 18,311 $ 19,490 See Note 15 - Business Segment, Geographic and Customer Information.

A total of 320,000 On May 11, 2011, the board of directors of the Company adopted the Pioneer Power Solutions, Inc. 2011 Long-Term Incentive Plan (the “2011 Plan”) which was subsequently approved by stockholders of the Company on May 31, 2011.

We are required to consider all available positive and negative evidence in evaluating the likelihood that we will be able to realize the benefit of our deferred tax assets in the future. Such evidence includes scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and the results of recent operations. Since this evaluation requires consideration of events that may occur some years into the future, there is an element of judgment involved. Realization of our deferred tax assets is dependent on generating sufficient taxable income in future periods. We do not believe that it is more likely than not that future taxable income will be sufficient to allow us to recover any of the value assigned to our deferred tax assets. Accordingly, we have provided for a valuation allowance of the Company’s foreign tax credits as we do not anticipate generating sufficient foreign source income. In addition, we have provided for a full valuation allowance on the domestic deferred tax assets as the combined effect of future domestic source income and the future reversals of future tax assets and liabilities will likely be insufficient to realize the full benefits of the assets. As of December 31, 2021, the Company has a net operating loss carryforward of $ 10.3 million 10.1 million 10.1 million 611 4.4 million 39 Section 382 of the Internal Revenue Code of 1986, as amended imposes an annual limitation on the amount of net operating loss carryforwards that may be used to offset federal taxable income and federal tax liabilities when a corporation has undergone significant changes in its ownership. If the Company experiences an ownership change as a result of future events, the use of tax attributes may be limited. Management believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. The tax years subject to examination by major tax jurisdiction include the years 2015 and forward by the U.S. Internal Revenue Service and most state jurisdictions, and the years 2016 and forward for the Canadian jurisdiction.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2021
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. GAAP 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 and the reported amounts of revenues and expenses during the reporting period. The financial statements include estimates based on currently available information and management’s judgment as to the outcome of future conditions and circumstances. Significant estimates in these financial statements include allowance for doubtful accounts receivable, inventory provision, useful lives and impairment of long-lived assets and income tax provision. Changes in the status of certain facts or circumstances could result in material changes to the estimates used in the preparation of the financial statements and actual results could differ from the estimates and assumptions.
Revenue Recognition	Revenue Recognition Revenue is recognized when (1) a contract with a customer exists, (2) performance obligations promised in a contract are identified based on the products or services that will be transferred to the customer, (3) the transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer, (4) the transaction price is allocated to the performance obligations in the contract and (5) the Company satisfies performance obligations. The Company satisfies performance obligations either over time or at a point in time. Revenue is recognized at the time the related performance obligation is satisfied by transferring a promised product or service to a customer. Revenue from the sale of our products is predominantly recognized at a point in time. Revenues are recognized at the point in time that the customer obtains control of the good which is when it has taken title to the products and has assumed the risks and rewards of ownership specified in the purchase order or sales agreement. Certain sales of highly customized large equipment are recognized over time when such equipment has no alternative use and the Company has an enforceable right to payment for performance completed to date. Revenue for such agreements is recognized under the input method based on cost incurred relative to the estimated cost expected to be consumed to complete the project. Service revenues include maintenance contracts that are recognized over time based on the contract term and repair services which are recognized as services are delivered.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold for the T&D Solutions and Critical Power segments primarily includes charges for materials, direct labor and related benefits, freight (inbound and outbound), direct supplies and tools, purchasing and receiving costs, inspection costs, internal transfer costs, warehousing costs and utilities related to production facilities and, where appropriate, an allocation of overhead. Cost of goods sold also includes indirect labor and infrastructure cost related to the provision of field services.
Financial Instruments	Financial Instruments The Company’s financial instruments consist primarily of cash, restricted cash, receivables, payables and debt instruments. The carrying values of these financial instruments approximate their respective fair values as they are either short-term in nature or carry interest rates which are periodically adjusted to market rates. Unless otherwise indicated, the carrying value of these financial instruments approximates their fair market value.
Concentrations	Concentrations The Company manages its accounts receivable credit risk by performing credit evaluations and monitoring amounts due from the Company’s customers. The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows: At December 31, 2021 and 2020, two customers represented approximately 43 42 For the year ended December 31, 2021, two customers represented approximately 41 34
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents comprise cash on hand, demand deposits and investments with an original maturity at the date of purchase of three months or less. Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash deposits. Accounts at each institution are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $ 250 9.7 million 7.3 million
Restricted Cash	Restricted Cash Restricted Cash consists of a cash collateral security agreement with a commercial bank which required the Company to pledge cash collateral as security for all unpaid reimbursement obligations owing to the commercial bank for an irrevocable standby letter of credit.
Accounts Receivable	Accounts Receivable The Company accounts for trade receivables at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. The Company writes off trade receivables when they are deemed uncollectible. The Company records recoveries of trade receivables previously written off when it receives them. Management considers the Company’s allowance for doubtful accounts, which was $ 140 69
Long-Lived Assets	Long-Lived Assets Depreciation and amortization for property, plant and equipment, and finite life intangible assets, is computed and included in cost of goods sold and in selling and administrative expense, as appropriate. Long-lived assets, consisting primarily of property, plant and equipment, are stated at cost less accumulated depreciation. Property, plant and equipment are depreciated using the straight line method, based on the estimated useful lives of the assets (buildings - 25 5 15 3 5 5 7 Historically, finite life intangible assets have consisted primarily of customer relationships in multiple categories that are specific to the businesses acquired and for which estimated useful lives were determined based on actual historical customer attrition rates. These finite life intangible assets were amortized by the Company over periods ranging from four to ten years. Long-lived assets and finite life intangible assets are reviewed for impairment whenever events or circumstances have occurred that indicate the remaining useful life of the asset may warrant revision or that the remaining balance of the asset may not be recoverable. Upon indications of impairment, or in the normal course of annual testing, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The measurement of possible impairment is generally estimated by the ability to recover the balance of an asset group from its expected future operating cash flows on an undiscounted basis. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value thereof. Determining asset groups and underlying cash flows requires the use of significant judgment.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method, based on the income tax laws and rates in the countries in which operations are conducted and income is earned. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Developing the provision for income taxes requires significant judgment and expertise in federal, international and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and, if necessary, any valuation allowances that may be required for deferred tax assets. The Company records a valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized. The Company believes that the deferred asset, net recorded as of December 31, 2021 and 2020 is realizable through future reversals of existing taxable temporary differences. If the Company was to subsequently determine that it would be able to realize deferred tax assets in the future in excess of its net recorded amount, an adjustment to deferred tax assets would increase net income for the period in which such determination was made. The Company will continue to assess the adequacy of the valuation allowance on a quarterly basis. The Company’s tax filings are subject to audit by various taxing authorities. The objective of accounting for income taxes is to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences or events that have been recognized in the Company’s financial statements or tax returns. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position (see “Unrecognized Tax Benefits” below). Income tax related interest and penalties are grouped with interest expense on the consolidated statement of operations.
Unrecognized Tax Benefits	Unrecognized Tax Benefits The Company accounts for unrecognized tax benefits in accordance with FASB ASC “Income Taxes” (“ASC 740”). ASC 740 prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements and provides guidance on de-recognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. ASC 740 contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon ultimate settlement with a taxing authority, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Additionally, ASC 740 requires the Company to accrue interest and related penalties, if applicable, on all tax positions for which reserves have been established consistent with jurisdictional tax laws. The Company’s policy is to recognize interest and penalties related to income tax matters as interest expense. See Note 14 - Income Taxes.
Share-Based Payments	Share-Based Payments The Company accounts for share based payments in accordance with the provisions of FASB ASC 718 “Compensation – Stock Compensation” and accordingly recognizes in its financial statements share based payments at their fair value. In addition, it recognizes in the financial statements an expense based on the grant date fair value of stock options granted to employees and directors. The expense is recognized on a straight line basis over the expected option life while taking into account the vesting period and the offsetting credit is recorded in additional paid-in capital. Upon exercise of options, the consideration paid together with the amount previously recorded as additional paid-in capital is recognized as capital stock. The Company estimates its forfeiture rate in order to determine its compensation expense arising from stock based awards. The Company uses the Black-Scholes Merton option pricing model to determine the fair value of the options. Non-employee members of the Board of Directors are deemed to be employees for the purposes of recognizing share-based compensation expense.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value using weighted average method and include the cost of materials, labor and manufacturing overhead. The Company uses estimates in determining the level of reserves required to state inventory at the lower of cost or market. The Company estimates are based on market activity levels, production requirements, the physical condition of products and technological innovation. Changes in any of these factors may result in adjustments to the carrying value of inventory. See Note 6 - Inventories.
Income (Loss) Per Share	Income (Loss) Per Share Basic income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common and common equivalent shares outstanding during the period. (See Note 16 - Basic and Diluted Net Loss Per Share).
