| Summary of Significant Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements are prepared in accordance with the U.S. GAAP. The consolidated financial statements include the financial statements of the Company and its subsidiaries. All significant inter-company transactions and balances among the Company and its subsidiaries are eliminated upon consolidation. |
| Functional Currency | Functional Currency The functional currency of Micronet Enertec is the U.S. dollar. The functional currency of certain subsidiaries is their local currency. The financial statements of those companies are included in consolidation, based on translation into U.S. dollars. Assets and liabilities are translated at year-end exchange rates, while revenues and expenses are translated at monthly average exchange rates during the year. Differences resulting from translation are presented in the consolidated statements of comprehensive income. |
| Use of Estimates | Use of Estimates The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. |
| Principles of Consolidation | Principles of Consolidation The consolidated financial statements comprise the results and position of the Company and its subsidiaries. Control is the power to govern the financial and operating policies of an entity so as to obtain benefits from its operating activities. In assessing control, legal and contractual rights, are taken into account. The consolidated financial statements of subsidiaries are included in the consolidated financial statements from the date that control is achieved until the date that control is lost. Intercompany transactions and balances are eliminated upon consolidation. |
| Cash and Cash Equivalents | Cash and Cash Equivalents Cash equivalents are considered by the Company to be highly-liquid investments, including inter-alia, short-term deposits with banks, which do not exceed maturities of three months at the time of deposit and which are not restricted. |
| Revenue Recognition | Revenue Recognition On January 1, 2018, the Company adopted ASC 606, “Revenue from Contracts with Customers,” or ASC 606, and all the related amendments (“new revenue standard”) with respect to all contracts using the modified retrospective method. A contract with a customer exists only when: the parties to the contract have approved it and are committed to perform their respective obligations, the Company can identify each party’s rights regarding the distinct goods or services to be transferred (“performance obligations”), the Company can determine the transaction price for the goods or services to be transferred, the contract has commercial substance and it is probable that the Company will collect the consideration to which it will be entitled in exchange for the goods or services that will be transferred to the customer. Revenues are recorded in the amount of consideration to which the Company expects to be entitled in exchange for performance obligations upon transfer of control to the customer, excluding amounts collected on behalf of other third parties and sales taxes. The amount of consideration to which the Company expects to be entitled varies as a result of rebates, chargebacks, returns and other allowances. The cumulative effect of initially applying the new revenue standard was immaterial for the quarter ended March 31, 2018, based on the adoption of ASC 606. |
| Allowance for Doubtful Accounts | Allowance for Doubtful Accounts The Company establishes an allowance for doubtful accounts to ensure trade and financing receivables are not overstated due to uncollectability. The allowance for doubtful accounts was based on specific receivables, which their collection, in the opinion of Company’s management, is in doubt. Trade receivables are charged off in the period in which they are deemed to be uncollectible. As of March 31, 2018, and December 31, 2017, the allowance for doubtful accounts amounted to $314 and $0, respectively. |
| Reclassifications | Reclassifications Certain balance sheet amounts and cash flow amounts have been reclassified to conform with the current year presentation. |
| Inventories | Inventories Inventories of raw materials are stated at the lower of cost (first-in, first-out basis) or realizable value. Cost of work in process is comprised of direct materials, direct production costs and an allocation of production overhead based on normal operating capacity. |
| Property and Equipment | Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated by the straight-line method over their estimated useful lives. Annual rates of depreciation are as follows: Leasehold improvements Over the shorter of the lease term or Machinery and equipment 7-14 years Furniture and fixtures 10-14 years Transportation equipment 7 years Computer equipment 3 years |
| Stock Based Compensation | Stock-Based Compensation The Company accounts for stock-based compensation under the fair market value method under which compensation cost is measured at the grant date based on the value of the award and is recognized over the vesting period, which is usually the service period. For stock options, fair value is determined using an option-pricing model that takes into account the stock price at the grant date, the exercise price, the expected life of the option, the volatility of the underlying stock, the expected dividends on it, and the risk-free interest rate over the expected life of the option. |
| Research and Development Costs | Research and Development Costs Research and development costs are charged to statements of income as incurred net of grants from the Israel Innovation Authority (formerly known as the Israel Office of the Chief Scientist of the Ministry of Economy). |
| Loss per Share | Loss per Share Basic net earnings per share are computed based on the weighted average number of shares of common stock outstanding during each year. |
| Long-Lived Assets and Intangible assets | Long-Lived Assets and Intangible assets Intangible assets that are not considered to have an indefinite useful life are amortized using the straight-line basis over their estimated useful lives. The Company evaluates property and equipment and purchased intangible assets with finite lives for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. The Company assesses the recoverability of the assets based on the undiscounted future cash flow and recognizes an impairment loss when the estimated undiscounted future cash flow expected to result from the use of the asset plus the net proceeds expected from disposition of the asset, if any, are less than the carrying value of the asset. When the Company identifies an impairment, it reduces the carrying amount of the asset to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values. During the three months ended March 31, 2018, and the year ended December 31, 2017, no indicators of impairment have been identified. |
| Goodwill | Goodwill Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. Goodwill is not amortized, but rather is subject to an annual impairment test. The Company has one continued operation, consisting of the MRM segment, and the entire goodwill was allocated to this MRM segment. The goodwill impairment tests are conducted in two steps. In the first step, the Company determines the fair value of the reporting unit. If the net book value of the reporting unit exceeds its fair value, the Company would then perform the second step of the impairment test which requires allocation of the reporting unit’s fair value of all of its assets and liabilities in a manner similar to an acquisition cost allocation, with any residual fair value being allocated to goodwill. The implied fair value of the goodwill is then compared to the carrying value to determine impairment, if any. |
| Comprehensive Income (Loss) | Comprehensive Income (Loss) Financial Accounting Standards Board, or FASB, ASC 220-10, “Reporting Comprehensive Income,” requires the Company to report in its consolidated financial statements, in addition to its net income, comprehensive income (loss), which includes all changes in equity during a period from non-owner sources including, as applicable, foreign currency items and other items. The Company’s other comprehensive income for all periods presented is related to the translation from functional currency to the presentation currency. |
| Income Taxes | Income Taxes Deferred taxes are determined utilizing the “asset and liability” method, whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and the tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance when it is more likely than not that deferred tax assets will not be realized in the foreseeable future. The Company applied FASB ASC Topic 740-10-25, “Income Taxes,” which provides guidance for recognizing and measuring uncertain tax positions and prescribes a threshold condition that a tax position must meet for any of the benefits of the uncertain tax position to be recognized in the financial statements. It also provides accounting guidance on derecognizing, classification and disclosure of these uncertain tax positions. The Company’s policy on classification of all interest and penalties related to unrecognized income tax positions, if any, is to present them as a component of income tax expense. |
| Financial Instruments | Financial Instruments 1. Concentration of credit risks: Financial instruments that have the potential to expose the Company to credit risks are mainly cash and cash equivalents, bank deposit accounts, marketable securities and trade receivables. The Company holds cash and cash equivalents, securities and deposit accounts at large banks in Israel, thereby substantially reducing the risk of loss. With respect to trade receivables, the risk is limited due to the geographical spreading, nature and size of the entities that constitute the Company’s customer base. The Company assesses the financial position of its customers prior to the engagement with them. The Company performs ongoing credit evaluations of its customers for the purpose of determining the appropriate allowance for doubtful accounts and generally does not require collateral. An appropriate allowance for doubtful accounts is included in the accounts. 2. Fair value measurement: The Company measures fair value and discloses fair value measurements for financial and non-financial assets and liabilities. Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The accounting standard establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are 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. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and considers counterparty credit risk in its assessment of fair value. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update, or ASU, No. 2016-02, which supersedes the lease accounting guidance in ASC 840, “Leases.” The new guidance requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. For lessees, leases will continue to be classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. The guidance is effective for reporting periods (interim and annual) beginning after December 15, 2018, for public companies, with early adoption permitted. The new guidance must be adopted using a modified retrospective approach. We are currently assessing the potential impact of this ASU on our consolidated financial position and results of operations. |
