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. Reclassifications Certain reclassifications have been made in prior years’ financial statements to conform to the presentation used in the current year. These reclassifications have not resulted in any changes to the previously reported net income for any year. 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, income tax provision, and goodwill impairment. 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. Substantially all of our revenue is recognized at a point of time, as the promised product passes to the customer. 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 for Critical Power Solutions 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 and cash equivalents, 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. The carrying amount reported in the consolidated balance sheet for shares held in CleanSpark, Inc., which are accounted for in accordance with the adoption of ASU 2016-01, of $936 included within short term investment approximates fair value as the asset has a readily determinable market value and as such it is considered a Level 1 asset. The estimated fair value of the warrants held in CleanSpark, Inc. of approximately $531 is considered a Level 3 asset due to unobservable inputs. 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. 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 $77 and $123 as of December 31, 2019 and 2018, respectively, sufficient to cover any exposure to loss in its accounts receivable. 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 years, machinery and equipment - 5 to 15 years, computer hardware and software - 3 to 5 years, furniture & fixtures 5 to 7 years, leasehold improvements – term of lease). Depreciation commences in the year the assets are ready for their intended use. As a convention, in the initial year an asset is placed in service, the Company takes one half year of depreciation. Finite life intangible assets consist 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. The Company’s other finite life intangible assets consist of non-compete agreements, which have defined terms, certain trademarks which the Company has elected to gradually discontinue, and internally-developed software. These finite life intangible assets are 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. Goodwill and Indefinite Life Intangible Assets Goodwill was generated through the acquisitions made by the Company between 2010 and 2015. As the total consideration paid exceeded the value of the net assets acquired, the Company recorded goodwill for each of the completed acquisitions. At the date of acquisition, the Company performed a valuation to determine the value of the intangible assets, and the allocation of the purchase price to the assets and liabilities acquired. The goodwill is attributable to synergies and economies of scale provided to us by the acquired entity. The Company tests its goodwill and indefinite-lived intangible asset for impairment at least annually (as of October 1) and whenever events or circumstances change that indicate impairment may have occurred. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others: a significant decline in the Company’s expected future cash flows; a sustained, significant decline in the Company’s stock price and market capitalization; a significant adverse change in legal factors or in the business climate of its segments; unanticipated competition; and slower growth rates. Any adverse change in these factors could have a significant impact on the recoverability of goodwill, the indefinite-lived intangible assets and the Company’s consolidated financial results. As described in Note 11, the Company recorded impairment charges of $83 for intangible assets and $3.0 million against goodwill in 2019 and $870, $377 and $103 against technology-related industry accreditation, customer relationships and non-complete agreements, respectively, in 2018. The Company tests its goodwill for impairment at the reporting unit level, which is an operating segment or a segment that is one level below its operating segments. An operating segment is defined by ASC 280-10-50 as a component of an enterprise that earns revenue and incurs expenses, of which discrete financial information is available. The goodwill has been assigned to the reporting unit to which the value relates. Two of the Company’s four reporting units have goodwill. The Company tests goodwill by estimating the fair value of the reporting unit using a discounted cash flow model and other valuation techniques, but may elect to perform a qualitative analysis. A quantitative analysis is used to determine an estimated fair value representing the amount at which a reporting unit could be bought or sold in a current transaction between willing parties on an arms-length basis. The estimated fair value of each reporting unit is derived using a discounted cash flow method based on market and reporting unit-specific assumptions, including estimated future revenues and expenses, weighted average cost of capital, capital expenditures, the useful life over which cash flows will occur and other assumptions which are considered reasonable and inherent in discounted cash flow analysis. A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative assessment. As of December 31, 2019, the Company has written the value of all of its goodwill and intangible assets to zero because the Company determined they were impaired. 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 tax asset recorded as of December 31, 2019 and 2018 is realizable through future reversals of existing taxable temporary differences and future taxable income. 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“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. See Note 16 ‒ 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 first-in, first-out (FIFO) or weighted-average methods 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 8 - 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 18 ‒ Basic and Diluted Net Loss Per Share). Fair Value Measurements FASB ASC 820 “Fair Value Measurement and Disclosure” applies to all assets and liabilities that are being measured and reported on a fair value basis. ASC 820 establishes a framework for measuring fair value in U.S GAAP, and expands disclosure about fair value measurements. ASC 820 enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. ASC 820 requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to ASC 820. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs are classified as Level 3. The fair value represents management’s best estimates based on a range of methodologies and assumptions. The carrying value of receivables and payables arising in the ordinary course of business approximate fair value because of the relatively short period of time between their origination and expected realization. The Company’s financial instruments consist primarily of cash and cash equivalents, receivables, notes receivable in connection with the Equity Transaction, 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. The carrying amount reported in the consolidated balance sheet for shares held in CleanSpark, Inc. of $936 included within short term investment approximates fair value as the asset has a readily determinable market value and as such it is considered a Level 1 asset. The estimated fair value of the warrants held in CleanSpark, Inc. of approximately $531 is considered a Level 3 asset due to unobservable inputs. 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. Income Taxes. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740), which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The ASU is effective for all annual and interim periods beginning December 15, 2020, with early adoption permitted. The Company is currently evaluating the potential impact but does not anticipate there will be an impact of the adoption of this standard on its results of a material impact to the consolidated financial statements once implemented. Leases. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires, among other things, a lessee to recognize a liability representing future lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. For operating leases, a lessee will be required to recognize at inception a right-of-use asset and a lease liability equal to the net present value of the lease payments, with lease expense recognized over the lease term on a straight-line basis. For leases with a term of twelve months or less, ASU 2016-02 allows a reporting entity to make an accounting policy election to not recognize a right-of-use asset and a lease liability, and to recognize lease expense on a straight-line basis. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. Upon adoption, a reporting entity should apply the provisions of ASU 2016-02 at the beginning of the earliest period presented using a modified retrospective approach, which includes certain optional practical expedients that an entity may elect to apply. We adopted this standard in our first quarter of 2018 using the modified retrospective approach. Revenue from Contracts with Customers. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. Since then, the FASB has also issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606), Principals versus Agent Considerations, ASU 2016-04, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing, and ASU 2017-13 Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842), Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Recession of Prior SEC Staff Announcements and Observer Comments, which further elaborate on the original ASU No. 2014-09. The core principle of these updates is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgments and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. In July 2015, the FASB approved a one-year deferral of the effective date to January 1, 2018, with early adoption to be permitted as of the original effective date of January 1, 2017. Once this standard becomes effective, companies may use either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients; or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures) (the “modified retrospective approach”). We completed a review of our various revenue streams within our two reportable segments, T&D Solutions and Critical Power. We have gathered data to quantify the amount of sales by type of revenue stream and categorized the types of sales for our business units for the purpose of comparing how we currently recognize revenue to the new standard in order to quantify the impact of this ASU. We have made policy elections within the amended standard that are consistent with our current accounting. We adopted ASU 2014-09 in our first quarter of 2018 using the modified retrospective approach. We have performed a quantitative assessment of adopting ASU 2014-09 and concluded that there was no material impact to our financial statements other than enhanced disclosures and no changes to the opening retained earnings. Stock Compensation. In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. The amendments in this update expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The updated standard is effective for the Company beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption of the new guidance is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company adopted this guidance on January 1, 2019. The adoption of this ASU did not have a material impact on the consolidated financial statements. Fair Value Measurement. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement that eliminates, amends, and adds certain disclosure requirements for fair value measurements. The ASU is effective for all annual and interim periods beginning January 1, 2020, with early adoption permitted. The Company does not anticipate material impact of adopting this ASU on its consolidated financial statements. Measurement of Credit Losses on Financial Instrument. In June 2016, the FASB issued amended guidance to ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments that changes the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that will replace today’s “incurred loss” model and generally will result in the earlier recognition of allowances for losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses in a manner similar to current practice, except that the losses will be recognized as an allowance. This amended guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first effective reporting period. We do not expect that the amended guidance will have a material effect on our consolidated financial statements and related disclosures.

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.

Reclassifications

Certain reclassifications have been made in prior years’ financial statements to conform to the presentation used in the current year. These reclassifications have not resulted in any changes to the previously reported net income for any year.

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, income tax provision, and goodwill impairment.

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. Substantially all of our revenue is recognized at a point of time, as the promised product passes to the customer. 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 for Critical Power Solutions 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 and cash equivalents, 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.

The carrying amount reported in the consolidated balance sheet for shares held in CleanSpark, Inc., which are accounted for in accordance with the adoption of ASU 2016-01, of $936 included within short term investment approximates fair value as the asset has a readily determinable market value and as such it is considered a Level 1 asset. The estimated fair value of the warrants held in CleanSpark, Inc. of approximately $531 is considered a Level 3 asset due to unobservable inputs.

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.

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 $77 and $123 as of December 31, 2019 and 2018, respectively, sufficient to cover any exposure to loss in its accounts receivable.

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 years, machinery and equipment - 5 to 15 years, computer hardware and software - 3 to 5 years, furniture & fixtures 5 to 7 years, leasehold improvements – term of lease). Depreciation commences in the year the assets are ready for their intended use. As a convention, in the initial year an asset is placed in service, the Company takes one half year of depreciation.

Finite life intangible assets consist 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. The Company’s other finite life intangible assets consist of non-compete agreements, which have defined terms, certain trademarks which the Company has elected to gradually discontinue, and internally-developed software. These finite life intangible assets are 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.

Goodwill and Indefinite Life Intangible Assets

Goodwill was generated through the acquisitions made by the Company between 2010 and 2015. As the total consideration paid exceeded the value of the net assets acquired, the Company recorded goodwill for each of the completed acquisitions. At the date of acquisition, the Company performed a valuation to determine the value of the intangible assets, and the allocation of the purchase price to the assets and liabilities acquired. The goodwill is attributable to synergies and economies of scale provided to us by the acquired entity.

The Company tests its goodwill and indefinite-lived intangible asset for impairment at least annually (as of October 1) and whenever events or circumstances change that indicate impairment may have occurred. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others: a significant decline in the Company’s expected future cash flows; a sustained, significant decline in the Company’s stock price and market capitalization; a significant adverse change in legal factors or in the business climate of its segments; unanticipated competition; and slower growth rates. Any adverse change in these factors could have a significant impact on the recoverability of goodwill, the indefinite-lived intangible assets and the Company’s consolidated financial results. As described in Note 11, the Company recorded impairment charges of $83 for intangible assets and $3.0 million against goodwill in 2019 and $870, $377 and $103 against technology-related industry accreditation, customer relationships and non-complete agreements, respectively, in 2018.

The Company tests its goodwill for impairment at the reporting unit level, which is an operating segment or a segment that is one level below its operating segments. An operating segment is defined by ASC 280-10-50 as a component of an enterprise that earns revenue and incurs expenses, of which discrete financial information is available. The goodwill has been assigned to the reporting unit to which the value relates. Two of the Company’s four reporting units have goodwill. The Company tests goodwill by estimating the fair value of the reporting unit using a discounted cash flow model and other valuation techniques, but may elect to perform a qualitative analysis. A quantitative analysis is used to determine an estimated fair value representing the amount at which a reporting unit could be bought or sold in a current transaction between willing parties on an arms-length basis. The estimated fair value of each reporting unit is derived using a discounted cash flow method based on market and reporting unit-specific assumptions, including estimated future revenues and expenses, weighted average cost of capital, capital expenditures, the useful life over which cash flows will occur and other assumptions which are considered reasonable and inherent in discounted cash flow analysis. A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative assessment.

As of December 31, 2019, the Company has written the value of all of its goodwill and intangible assets to zero because the Company determined they were impaired.

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 tax asset recorded as of December 31, 2019 and 2018 is realizable through future reversals of existing taxable temporary differences and future taxable income. 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“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. See Note 16 ‒ 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 first-in, first-out (FIFO) or weighted-average methods 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 8 - 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 18 ‒ Basic and Diluted Net Loss Per Share).

Fair Value Measurements

FASB ASC 820 “Fair Value Measurement and Disclosure” applies to all assets and liabilities that are being measured and reported on a fair value basis. ASC 820 establishes a framework for measuring fair value in U.S GAAP, and expands disclosure about fair value measurements. ASC 820 enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. ASC 820 requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to ASC 820. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs are classified as Level 3.

The fair value represents management’s best estimates based on a range of methodologies and assumptions. The carrying value of receivables and payables arising in the ordinary course of business approximate fair value because of the relatively short period of time between their origination and expected realization.

The Company’s financial instruments consist primarily of cash and cash equivalents, receivables, notes receivable in connection with the Equity Transaction, 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.

The carrying amount reported in the consolidated balance sheet for shares held in CleanSpark, Inc. of $936 included within short term investment approximates fair value as the asset has a readily determinable market value and as such it is considered a Level 1 asset. The estimated fair value of the warrants held in CleanSpark, Inc. of approximately $531 is considered a Level 3 asset due to unobservable inputs.

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.

Income Taxes. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740), which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The ASU is effective for all annual and interim periods beginning December 15, 2020, with early adoption permitted. The Company is currently evaluating the potential impact but does not anticipate there will be an impact of the adoption of this standard on its results of a material impact to the consolidated financial statements once implemented.

Leases. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires, among other things, a lessee to recognize a liability representing future lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. For operating leases, a lessee will be required to recognize at inception a right-of-use asset and a lease liability equal to the net present value of the lease payments, with lease expense recognized over the lease term on a straight-line basis. For leases with a term of twelve months or less, ASU 2016-02 allows a reporting entity to make an accounting policy election to not recognize a right-of-use asset and a lease liability, and to recognize lease expense on a straight-line basis. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. Upon adoption, a reporting entity should apply the provisions of ASU 2016-02 at the beginning of the earliest period presented using a modified retrospective approach, which includes certain optional practical expedients that an entity may elect to apply. We adopted this standard in our first quarter of 2018 using the modified retrospective approach.

Revenue from Contracts with Customers. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. Since then, the FASB has also issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606), Principals versus Agent Considerations, ASU 2016-04, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing, and ASU 2017-13 Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842), Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Recession of Prior SEC Staff Announcements and Observer Comments, which further elaborate on the original ASU No. 2014-09. The core principle of these updates is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgments and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. In July 2015, the FASB approved a one-year deferral of the effective date to January 1, 2018, with early adoption to be permitted as of the original effective date of January 1, 2017. Once this standard becomes effective, companies may use either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients; or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures) (the “modified retrospective approach”). We completed a review of our various revenue streams within our two reportable segments, T&D Solutions and Critical Power. We have gathered data to quantify the amount of sales by type of revenue stream and categorized the types of sales for our business units for the purpose of comparing how we currently recognize revenue to the new standard in order to quantify the impact of this ASU. We have made policy elections within the amended standard that are consistent with our current accounting. We adopted ASU 2014-09 in our first quarter of 2018 using the modified retrospective approach. We have performed a quantitative assessment of adopting ASU 2014-09 and concluded that there was no material impact to our financial statements other than enhanced disclosures and no changes to the opening retained earnings.

Stock Compensation. In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. The amendments in this update expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The updated standard is effective for the Company beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption of the new guidance is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company adopted this guidance on January 1, 2019. The adoption of this ASU did not have a material impact on the consolidated financial statements.

Fair Value Measurement. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement that eliminates, amends, and adds certain disclosure requirements for fair value measurements. The ASU is effective for all annual and interim periods beginning January 1, 2020, with early adoption permitted. The Company does not anticipate material impact of adopting this ASU on its consolidated financial statements.

Measurement of Credit Losses on Financial Instrument. In June 2016, the FASB issued amended guidance to ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments that changes the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that will replace today’s “incurred loss” model and generally will result in the earlier recognition of allowances for losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses in a manner similar to current practice, except that the losses will be recognized as an allowance. This amended guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first effective reporting period. We do not expect that the amended guidance will have a material effect on our consolidated financial statements and related disclosures.
