Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Dec. 31, 2020
Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).
Principles of Consolidation and Presentation | Principles of Consolidation and Presentation The consolidated financial statements include the accounts of the Company and its subsidiaries. In these consolidated financial statements, “subsidiaries” are companies that are over 50% controlled, the accounts of which are consolidated with those of the Company. Significant intercompany transactions and balances are eliminated in consolidation; profits from intercompany sales are also eliminated; non-controlling interests are included in equity.
Reclassification | Reclassification Certain reclassifications have been made to the Company’s consolidated financial statements for the year ended December 31, 2019 to conform to the current period’s consolidated financial statement presentation. There was no effect on total assets, equity and net loss. A reclassification of approximately $6,000 from finance expense to SG&A expense was recorded to reclass the Intuit processing fees for customer payments made through the Intuit portal via credit card or bank draft that was previously included in finance expense and is included in SG&A as of December 31, 2019.
Use of Estimates in Preparation of Financial Statements | Use of Estimates in Preparation of Financial Statements The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods. As applicable to these consolidated financial statements, the most significant estimates and assumptions relate to uncertainties with respect to income taxes, inventories, account receivable allowances, contingencies, revenue recognition, management’s projections and analyses of the possible impairments.
Accounts Receivable | Accounts Receivable Accounts receivable consists of trade receivables. Trade receivables are recorded at the invoiced amount.
Allowance for Doubtful Accounts | Allowance for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. This allowance is based on specific customer account reviews and historical collections experience. If the financial condition of the Company’s funding parties or customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company performs ongoing credit evaluations of its customers and does not require collateral. During the years ended December 31, 2020 and 2019, approximately $21,000 and $14,000 was charged to expense, respectively. At December 31, 2020 and 2019, the balance in allowance for doubtful accounts was approximately $9,000 and $11,000, respectively.
Inventory | Inventory Inventories are comprised of components (raw materials), work-in-process and finished goods, which are measured at net realizable value. Raw materials inventory is generally comprised of radios, cables, antennas, and electrical components. Finished goods inventory consists of fully assembled systems ready for final shipment to the customer. Costs are determined at cost of acquisition on a weighted average basis and include all outside production and applicable shipping costs. All inventories are periodically reviewed for impairment related to slow-moving and obsolete inventory. Management conducted an assessment and there were no impairment charges for the years ended December 31, 2020 or 2019.
Non-Controlling Interests | Non-Controlling Interests The Financial Accounting Standards Board (“FASB”) requires that non-controlling interests be reported as a component of equity, changes in a parent’s ownership interest while the parent retains its controlling interest be accounted for as equity transactions, and upon a loss of control, retained ownership interest be re-measured at fair value, with any gain or loss recognized in earnings. The Company attributes the applicable percentage of income and losses to the non-controlling interests associated with OmniMetrix (see Note 3).
Property and Equipment | Property and Equipment Property and equipment are presented at cost at the date of acquisition. Depreciation and amortization are calculated based on the straight-line method over the estimated useful lives of the depreciable assets, or in the case of leasehold improvements, the shorter of the lease term or the estimated useful life of the asset, a portion of which is allocated to cost of sales. Improvements are capitalized while repairs and maintenance are charged to operations as incurred.
Capitalization of Software | Capitalization of Software In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15 (“ASU 2018-15”), Intangibles - Goodwill and Other - Internal-Use Software (Topic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company elected to early adopt ASU 2018-15 for the period beginning in the second quarter of 2019, applying the guidance under ASU 2018-15 prospectively. During the years ended December 31, 2020 and 2019, the Company capitalized costs totaling approximately $87,000 and $163,000, respectively, related to such contracts.
Leases | Leases The Company determines if a contractual arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and noncurrent operating lease liabilities on the Company’s consolidated balance sheets. The Company evaluates and classifies leases as operating or finance leases for financial reporting purposes. The classification evaluation begins at the commencement date and the lease term used in the evaluation includes the non-cancellable period for which the Company has the right to use the underlying asset, together with renewal option periods when the exercise of the renewal option is reasonably certain and failure to exercise such option would result in an economic penalty. All the Company’s real estate leases are classified as operating leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date of the lease based on the present value of the lease payments over the lease term. The lease payments included in the present value are fixed lease payments. As most of the Company’s leases do not provide an implicit rate, the Company estimates its collateralized incremental borrowing rate, based on information available at the commencement date, in determining the present value of lease payments. The Company applies the portfolio approach in applying discount rates to its classes of leases. The operating lease ROU assets include any payments made before the commencement date. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company does not currently have subleases. The Company does not currently have residual value guarantees or restrictive covenants in its leases. The Company also made accounting policy elections by class of underlying asset to not apply the recognition requirements of the standard to leases with terms of 12 months or less and to not separate non-lease components from lease components. Consequently, each separate lease component and the non-lease components associated with that lease component will be accounted for as a single lease component for lease classification, recognition, and measurement purposes. The lease obligation liability was approximately $542,000 and $595,000 as of December 31, 2020 and December 31, 2019, respectively, which includes the original office space lease, an amendment to this lease entered into in November 2019 that became effective with the period beginning May 1, 2020, and an office equipment lease entered into in April 2019.
Treasury Stock | Treasury Stock Shares of common stock repurchased are recorded at cost as treasury stock. When shares are reissued, the cost method is used for determining cost. In accordance with GAAP, the excess of the acquisition cost over the reissuance price of the treasury stock, if any, is charged to additional paid-in capital, limited to the amount previously credited to additional paid-in capital, if any. Any excess is charged to accumulated deficit.
Revenue Recognition | Revenue Recognition The Company’s revenue recognition policy is consistent with applicable revenue recognition guidance and interpretations. The core principle of ASC 606 is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASC 606 defines a five-step process to achieve this core principle, which includes: (1) identifying contracts with customers, (2) identifying performance obligations within those contracts, (3) determining the transaction price, (4) allocating the transaction price to the performance obligation in the contract, which may include an estimate of variable consideration, and (5) recognizing revenue when or as each performance obligation is satisfied. The Company assesses whether payment terms are customary or extended in accordance with normal practice relative to the market in which the sale is occurring. The Company’s sales arrangements generally include standard payment terms. These terms effectively relate to all customers, products, and arrangements regardless of customer type, product mix or arrangement size. If revenue recognition criteria are not satisfied, amounts received from customers are classified as deferred revenue on the balance sheet until such time as the revenue recognition criteria are met. Sales of OmniMetrix monitoring systems include the sale of equipment (“HW”) and of monitoring services (“Monitoring”). The majority of the sales of OmniMetrix equipment do not qualify as a separate unit of accounting. As a result, revenue (and related costs) associated with sale of equipment are recorded to deferred revenue (and deferred charges) upon shipment for PG and CP monitoring units. Revenue and related costs with respect to the sale of equipment are recognized over the estimated life of the units which are currently estimated to be three years. In the rare instance that a specific sale of OmnMetrix equipment does qualify as a separate unit of accounting (the unit is custom designed and sold without monitoring), the revenue is recognized when the unit is shipped to the customer and not deferred. Revenues from the prepayment of monitoring fees (generally paid twelve months in advance) are initially recorded as deferred revenue upon receipt of payment from the customer and then amortized to revenue over the monitoring service period. See Notes 12 and 13 for the disaggregation of the Company’s revenue for the periods presented.
Warranty Provision | Warranty Provision OmniMetrix generally grants their customers a one-year warranty on their products. Estimated warranty obligations are provided for as a cost of sales in the period in which the related revenues are recognized, based on management’s estimate of future potential warranty obligations and limited historical experience. Adjustments are made to accruals as warranty claim data and historical experience warrant. The Company’s warranty obligations may be materially affected by product or service failure rates and other costs incurred in correcting a product or service failure. Should actual product or service failure rates or other related costs differ from the Company’s estimates, revisions to the accrued warranty liability would be required.
Concentration of Credit Risk | Concentration of Credit Risk The Company’s financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, escrow deposits and trade accounts receivable. The Company’s cash was deposited with a U.S. bank and amounted to approximately $2,063,000 at December 31, 2020. The Company does not believe there is significant risk of non-performance by these counterparties. See Note 12(d) with respect to revenue from significant customers and concentrations of trade accounts receivables.
Financial Instruments | Financial Instruments Fair values of financial instruments included in current assets and current liabilities are estimated to approximate their book values, due to the short maturity of such instruments.
Research and Development Expenses | Research and Development Expenses Research and development expenses consist primarily of labor and related expenses and are charged to operations as incurred.
Advertising Expenses | Advertising Expenses Advertising expenses are charged to operations as incurred. Advertising expense was approximately $15,000 and $17,000 for each of the years ended December 31, 2020 and 2019, respectively, and are included in selling, general and administrative expenses on the consolidated statements of operations.
Stock-Based Compensation | Stock-Based Compensation The Company accounts for stock-based awards to employees in accordance with applicable accounting principles, which requires compensation expense related to share-based transactions, including employee stock options, to be measured and recognized in the consolidated financial statements based on a determination of the fair value of the stock options. The grant date fair value is determined using the Black-Scholes-Merton (“Black-Scholes”) pricing model. For all employee stock options, the Company recognizes expense over the requisite service period on an accelerated basis over the employee’s requisite service period (generally the vesting period of the equity grant). Stock compensation expense is included in selling, general and administrative expenses. The Company’s option pricing model requires the input of highly subjective assumptions, including the expected stock price volatility, expected term, and forfeiture rate. Any changes in these highly subjective assumptions significantly impact stock-based compensation expense. Options awarded to purchase shares of common stock issued to non-employees in exchange for services are accounted for as variable awards in accordance with applicable accounting principles. Such options are valued using the Black-Scholes option pricing model. See Note 9(c) for the assumptions used to calculate the fair value of stock-based employee compensation. Upon the exercise of options, it is the Company’s policy to issue new shares rather than utilizing treasury shares.
Deferred Income Taxes | Deferred Income Taxes Deferred income taxes reflects the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, as well as operating loss, capital loss and tax credit carryforwards. Deferred tax assets and liabilities are classified as non-current in accordance with ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. Valuation allowances are established against deferred tax assets if it is more likely than not that the assets will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or laws is recognized in operations in the period that includes the enactment date. See Note 10(e) for the impact of the Tax Cuts and Jobs Act of 2017.
Income Tax Uncertainties | Income Tax Uncertainties The calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for uncertain tax positions based on the two-step process prescribed by applicable accounting principles. 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 on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax benefit as the largest amount that is more likely than not being realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as this requires the Company to determine the probability of various possible outcomes. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit, and new audit activity. Such a change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision in the period. The Company recognizes interest and penalties as incurred in finance income (expense), net in the consolidated statements of operations. As of December 31, 2020 and 2019, no interest or penalties were accrued on the consolidated balance sheets related to uncertain tax positions. During the years ending December 31, 2020 and 2019, the Company had no changes in unrecognized tax benefits or associated interest and penalties as a result of tax positions made during the current or prior periods with respect to its continuing or discontinued operations. The Company is subject to U.S. Federal and state income tax. As of January 1, 2020, the Company is no longer subject to examination by U.S. Federal taxing authorities for years before 2017, or for years before 2016 for state income taxes.
Basic and Diluted Net Income (loss) Per Share | Basic and Diluted Net Income (Loss) Per Share Basic net income (loss) per share is computed by dividing the net income (loss) attributable to Acorn Energy, Inc. by the weighted average number of shares outstanding during the year, excluding treasury stock. Diluted net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of shares outstanding plus the dilutive potential of common shares which would result from the exercise of stock options and warrants. The dilutive effects of stock options and warrants are excluded from the computation of diluted net loss per share if doing so would be antidilutive. The weighted average number of options and warrants that were excluded from the computation of diluted net loss per share, as they had an antidilutive effect, was approximately 409,626 (which have a weighted average exercise price of $0.84) and 3,368,013 for the years ending December 31, 2020 and 2019, respectively. The following data represents the amounts used in computing EPS and the effect on net income and the weighted average number of shares of dilutive potential common stock (in thousands):
|  | Year ended December 31, |
|  | 2020 |  |  | 2019 |

-Diluted |  |  | 39,713 |  |  |  | 35,495 |
Basic and diluted net loss per share |  | $ | 0.00 |  |  | $ | (0.02 | )
Fair Value Measurement | Fair Value Measurement The Company follows the provisions of the accounting standard which defines fair value, establishes a framework for measuring fair value and enhances fair value measurement disclosure. Under these provisions, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. The standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use on unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is described below: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.
Recently Issued Accounting Principles | Recently Issued Accounting Principles Other than the pronouncement noted below, there have been no recent accounting pronouncements or changes in accounting pronouncements during the year ended December 31, 2020, that are of material significance, or have potential material significance, to the Company. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (“ASC 326”), authoritative guidance amending how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance requires the application of a current expected credit loss model, which is a new impairment model based on expected losses. The new guidance is effective for interim and annual reporting periods beginning after December 15, 2022. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures.
Recently Adopted Accounting Principles | Recently Adopted Accounting Principles In June 2018, the FASB issued ASU 2018-07, which simplifies the accounting for nonemployee share-based payment transactions. 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. This standard was effective in the first quarter of fiscal year 2020, and the adoption did not have a material impact on the consolidated financial statements. Other recently issued accounting updates are not expected to have a material impact on the Company’s consolidated financial statements.
