Accounting Policies [Abstract]
1. Summary of Significant Accounting Policies	Description of Business The primary business of BK Technologies, Inc. and its subsidiaries (collectively, the “Company”) is the designing, manufacturing and marketing of wireless communications equipment primarily consisting of two-way land mobile radios and related products, which are sold in two primary markets: (1) the government and public safety market, and (2) the business and industrial market. The Company has only one reportable business segment. Principles of Consolidation The accounts of the Company have been included in the accompanying consolidated financial statements. All significant intercompany balances and transactions have been eliminated in consolidation. The Company consolidates entities in which it has a controlling financial interest. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a variable interest entity (“VIE”) or a voting interest entity. VIEs are entities in which (i) the total equity investment at risk is not sufficient to enable the entity to finance its activities independently, or (ii) the at-risk equity holders do not have the normal characteristics of a controlling financial interest. A controlling financial interest in a VIE is present when an enterprise has one or more variable interests that have both (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The enterprise with a controlling financial interest is the primary beneficiary and consolidates the VIE. Voting interest entities lack one or more of the characteristics of a VIE. The usual condition for a controlling financial interest is ownership of a majority voting interest for a corporation or a majority of kick-out or participating rights for a limited partnership. When the Company does not have a controlling financial interest in an entity but exerts significant influence over the entity’s operating and financial policies (generally defined as owning a voting or economic interest of between 20% to 50%), the Company’s investment is accounted for under the equity method of accounting. If the Company does not have a controlling financial interest in, or exert significant influence over, an entity, the Company accounts for its investment at fair value, if the fair value option was elected, or at cost. The Company has an investment in 1347 Property Insurance Holdings, Inc., made through FGI 1347 Holdings, LP, a consolidated VIE. Inventories Inventories are stated at the lower of cost (determined by the average cost method) or net realizable value. Freight costs are classified as a component of cost of products in the accompanying consolidated statements of operations. The allowance for slow-moving, excess, or obsolete inventory is used to state the Company’s inventories at the lower of cost and net realizable value. Because the amount of inventory that will actually be recouped through sales cannot be known with certainty at any particular time, the Company relies on past sales experience, future sales forecasts, and its strategic business plans. Generally, in analyzing inventory levels, inventory is classified as having been used or unused during the past year. The Company then establishes an allowance based upon several factors, including, but not limited to, business forecasts, inventory quantities and historic usage profile. Supplemental to the aforementioned analysis, specific inventory items are reviewed individually by management. Based on the review, considering business levels, future prospects, new products and technology changes, management, using its business judgment, may adjust the valuation of specific inventory items to reflect an accurate valuation. Management also performs a determination of net realizable value for all finished goods with a selling price below cost. For all such items, the inventory is valued at not more than the selling price less cost, if any, to sell. Property, Plant and Equipment Property, plant and equipment is carried at cost. Expenditures for maintenance, repairs and minor renewals are expensed as incurred. When properties are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is reflected in operations for the period. Depreciation and amortization are generally computed on the straight-line method using lives of 3 to 10 years for machinery and equipment and 5 to 8 years for leasehold improvements. Impairment of Long-Lived Assets Management regularly reviews long-lived assets and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds their fair value, which considers the discounted future net cash flows. No long-lived assets were considered impaired at December 31, 2018 and 2017. Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Allowance for Doubtful Accounts The Company records an allowance for doubtful accounts based on specifically identified amounts that the Company believes to be uncollectible. The Company also records an additional allowance based on certain percentages of the Company’s aged receivables, which are determined based on historical experience and the Company’s assessment of the general financial conditions affecting the Company’s customer base. If the Company’s actual collections experience changes, revisions to the Company’s allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. Based on the information available, management believes the allowance for doubtful accounts as of December 31, 2018 and 2017 is adequate. Revenue Recognition Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” and the additional related ASUs (“ASC 606”), which replaces existing revenue guidance and outlines a single set of comprehensive principles for recognizing revenue under accounting principles generally accepted in the United States of America (“GAAP”). The Company elected the modified retrospective method upon adoption, with no impact to the opening retained earnings or revenue reported. These standards provide guidance on recognizing revenue, including a five-step method to determine when revenue recognition is appropriate: Step 1: Identify the contract with the customer; Step 2: Identify the performance obligations in the contract; Step 3: Determine the transaction price; Step 4: Allocate the transaction price to the performance obligations; and Step 5: Recognize revenue as the Company satisfies a performance obligation. ASC 606 provides that sales revenue is recognized when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The Company generally satisfies performance obligations upon shipment of the product or service to the customer. This is consistent with the time in which the customer obtains control of the product or service. For extended warranties, sales revenue associated with the warranty is deferred at the time of sale and later recognized on a straight-line basis over the extended warranty period. Some contracts include installation services, which are completed in a short period of time and the revenue is recognized when the installation is complete. Customary payment terms are granted to customers, based on credit evaluations. Currently, the Company does not have any contracts where revenue is recognized, but the customer payment is contingent on a future event. The Company periodically reviews its revenue recognition procedures to assure that such procedures are in accordance with GAAP. Surcharges collected on certain sales to government customers and remitted to governmental agencies are not included in revenues or in costs and expenses. Income Taxes The Company accounts for income taxes using the asset and liability method specified by GAAP. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply in the period in which the deferred tax asset or liability is expected to be realized. The effect of changes in net deferred tax assets and liabilities is recognized on the Company’s consolidated balance sheets and consolidated statements of operations in the period in which the change is recognized. Valuation allowances are provided to the extent that impairment of tax assets is more likely than not. In determining whether a tax asset is realizable, the Company considers, among other things, estimates of future earnings based on information currently available, current and anticipated customers, contracts and new product introductions, as well as recent operating results during 2018 and 2017 and certain tax planning strategies. If the Company fails to achieve the future results anticipated in the calculation and valuation of net deferred tax assets, the Company may be required to adjust the valuation allowance related to its deferred tax assets in the future. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “2017 Tax Act”). The 2017 Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35% to 21%; (2) eliminating the corporate alternative minimum tax (“AMT”) and changing how existing AMT credits can be realized; and (3) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017. In connection with the Company’s initial analysis of the impact of the 2017 Tax Act, the Company recorded a discrete net tax expense of $665 in the year ended December 31, 2017 for the effect of the corporate rate reduction, which was finalized as of December 31, 2018. The net tax expense primarily relates to a reduction in the deferred tax assets of $1,524 and a reduction in the deferred tax liability related to unrealized gain on available-for-sale securities of $(859). Concentration of Credit Risk The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. At December 31, 2018 and 2017, accounts receivable from governmental customers were approximately $3,331 and $2,663, respectively. Generally, receivables are due within 30 days. Credit losses relating to customers have been consistently within management’s expectations. The Company primarily maintains cash balances at one financial institution. Accounts are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250. From time to time, the Company has had cash in financial institutions in excess of federally insured limits. As of December 31, 2018, the Company had cash and cash equivalents in excess of FDIC limits of $11,050. Manufacturing and Raw Materials The Company relies upon a limited number of manufacturers to produce its products and on a limited number of component suppliers. Some of these manufacturers and suppliers are in other countries. Approximately 66.8% of the Company’s material, subassembly and product procurements in 2018 were sourced internationally, of which approximately 60.0% were sourced from two suppliers. For 2017, approximately 65.7% of the Company’s material, subassembly and product procurements were sourced internationally, of which approximately 61.6% were sourced from three suppliers. Purchase orders denominated in U.S. dollars are placed with these suppliers from time to time and there are no guaranteed supply arrangements or commitments. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of sales and expenses during the reporting period. Significant estimates include accounts receivable allowances, inventory obsolescence allowance, warranty allowance, and income tax accruals. Actual results could differ from those estimates. Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, trade accounts receivable, available-for-sale securities, investment in securities, accounts payable, accrued expenses and other liabilities. As of December 31, 2018 and 2017, the carrying amount of cash and cash equivalents, trade accounts receivable, accounts payable, accrued expenses and other liabilities approximated their respective fair value due to the short-term nature and maturity of these instruments. The Company uses observable market data or assumptions (Level 1 inputs, as defined in accounting guidance) that it believes market participants would use in pricing the available-for-sale securities and investment in securities. There were no sales of available-for-sale securities or investment in securities, as a result of an other-than-temporary impairment of the available-for-sale securities. There were no transfers of available-for-sale securities or investments in securities between Level 1 and Level 2 during the years ended December 31, 2018 and 2017. Available-For-Sale Securities Investments reported on the December 31, 2017 balance sheet consisted of marketable equity securities of a publicly held company. As of December 31, 2017, the investment cost was $2,402. On January 1, 2018, the Company adopted ASU 2016-01 “Financial Instruments,” which amended the guidance in GAAP regarding the classification and measurement of financial instruments. Changes to the prior guidance primarily affected the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. Upon its adoption, the Company applied the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance was effective. On January 1, 2018, the Company recognized approximately $4,300 of net unrealized gain in its accumulated deficit balance. During the first quarter of 2018, the Company sold 1,317,503 shares of Iteris, Inc. (Nasdaq: ITI), which cost $2,402, for approximately $8,335 of proceeds and reported a loss on the sale of approximately $849. Shipping and Handling Costs Shipping and handling costs are classified as a part of cost of products in the accompanying consolidated statements of operations for the years ended December 31, 2018 and 2017. Amounts billed to a customer, if any, for shipping and handling are reported as revenue. Advertising and Promotion Costs The cost for advertising and promotion is expensed as incurred. Advertising and promotion expenses are classified as part of selling, general and administrative (“SG&A”) expenses in the accompanying consolidated statements of operations. For the years ended December 31, 2018 and 2017, such expenses totaled $597 and $424, respectively. Engineering, Research and Development Costs Included in SG&A expenses for the years ended December 31, 2018 and 2017 are engineering, research and development costs of $7,768 and $5,000, respectively. Share-Based Compensation The Company accounts for share-based arrangements in accordance with GAAP, which requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award (with limited exceptions). That cost will be recognized over the period during which the employee is required to provide service in exchange for the award requisite service period (usually the vesting period). No compensation cost is recognized for equity instruments for which employees do not render the requisite service. Employee share purchase plans will not result in recognition of compensation cost if certain conditions are met. Restricted Stock Units On September 6, 2018, the Company granted to each non-employee director restricted stock units with a grant fair value of $20 per award (resulting in total aggregate grant-date fair value of $140), which will vest in five equal, annual installments beginning with the first anniversary of the grant date, subject to the director’s continued service through such date, provided that, if the director makes himself available and consents to be nominated by the Company for continued service as a director, but is not nominated for the Board for election by shareholders, other than for good reason, as determined by the Board in its discretion, then the restricted stock units shall vest in full as of the director’s last date of service as a director of the Company. On June 4, 2018, the Company granted to each non-employee director restricted stock units with a grant fair value of $20 per award (resulting in total aggregate grant-date fair value of $140), which will vest on June 4, 2019, subject to continued service through such vesting date. On June 15, 2017, the Company granted to each non-employee director restricted stock units with a grant fair value of $20 per award (resulting in total aggregate grant-date fair value of $140), which vested on June 15, 2018. The Company recorded non-cash restricted stock unit compensation expense of $153 and $76 for the years ended December 31, 2018 and 2017, respectively. Earnings (Loss) Per Share Earnings (loss) per share amounts are computed and presented for all periods in accordance with GAAP. Other Comprehensive Loss Other comprehensive loss consists of net loss and unrealized gain on available-for-sale securities, net of taxes. Product Warranty The Company offers two-year warranties to its customers, depending on the specific product and terms of the customer purchase agreement. The Company’s typical warranties require it to repair and replace defective products during the warranty period at no cost to the customer. At the time the product revenue is recognized, the Company records a liability for estimated costs under its warranties. The costs are estimated based on historical experience. The Company periodically assesses the adequacy of its recorded liability for product warranties and adjusts the amount as necessary. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications had no impact on previously reported net loss for the year ended December 31, 2017. Recently Adopted Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 on “Revenue from Contracts with Customers,” which provided for a single, principles-based model for revenue recognition and replaced the existing revenue recognition guidance. In August 2015, the FASB issued ASU 2015-14, which delayed the effective date of ASU 2014-09 by one year. The guidance became effective for annual and interim periods beginning on or after December 15, 2017, and replaced most existing revenue recognition guidance under GAAP when it became effective. This ASU required additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and estimates and changes in those estimates. It permitted the use of either a retrospective or cumulative effect transition method. The Company adopted ASU 2014-09 in the first quarter of 2018 and applied the modified retrospective approach. Because the Company’s primary source of revenues is from shipments of products, the adoption of ASU 2014-09 did not have a material impact on its consolidated financial statements. See Note 1, under “Revenue Recognition,” for additional information. In January 2016, the FASB issued ASU 2016-01 “Financial Instruments,” which amended the guidance in GAAP on the classification and measurement of financial instruments. Changes to the previous guidance primarily affected the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The new standard became effective for fiscal years and interim periods beginning after December 15, 2017, and upon adoption, an entity was required to apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. On January 1, 2018, the Company adopted the new guidance and, consequently, the Company recognized approximately $4,300 of net unrealized gain in its accumulated deficit balance. In August 2018, the FASB issued ASU 2018-15, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement) by providing guidance for determining when the arrangement includes a software license. The amendments in ASU 2018-15 align 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 (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in ASU 2018-15. The amendments in ASU 2018-15 will become effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period. The Company adopted the new guidance in the fourth quarter of 2018, with no material impact on its consolidated financial statements and related disclosures. Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, “Leases,” which amends leasing guidance by requiring companies to recognize a right-of-use asset and a lease liability for all operating and capital (finance) leases with lease terms greater than twelve months. The lease liability will be equal to the present value of lease payments. The lease asset will be based on the lease liability, subject to adjustment, such as for initial direct costs. For income statement purposes, leases will continue to be classified as operating or capital (finance), with lease expense in both cases calculated substantially the same as under the prior leasing guidance. The updated guidance is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company expects this will result in the recognition of right-of-use assets and lease liabilities not currently recorded on the consolidated financial statements under existing accounting guidance. Based on the Company’s evaluation of all of its contractual arrangements, the Company expects that the adoption of ASU 2016-02 will have a significant impact on the Company’s consolidated financial statements. After the adoption, the Company will first report the operating lease right-of-use assets and lease liabilities as of March 31, 2019 based on our lease portfolio as of that date. In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, “Disclosure Update and Simplification,” amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders’ equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders’ equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed. This final rule is effective for all filings made on or after November 5, 2018. Given the effective date and the proximity to most filers’ quarterly reports, the SEC is not objecting to filers deferring the presentation of interim changes in stockholders’ equity in their Forms 10-Q until the quarter that begins after the date of adoption, November 5, 2018. The Company intends to present interim changes in stockholders’ equity beginning with its quarterly report on Form 10-Q for the first quarter of 2019. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.

1. Summary of Significant Accounting Policies

Description of Business

The primary business of BK Technologies, Inc. and its subsidiaries (collectively, the “Company”) is the designing, manufacturing and marketing of wireless communications equipment primarily consisting of two-way land mobile radios and related products, which are sold in two primary markets: (1) the government and public safety market, and (2) the business and industrial market. The Company has only one reportable business segment.

Principles of Consolidation

The accounts of the Company have been included in the accompanying consolidated financial statements. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company consolidates entities in which it has a controlling financial interest. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a variable interest entity (“VIE”) or a voting interest entity.

VIEs are entities in which (i) the total equity investment at risk is not sufficient to enable the entity to finance its activities independently, or (ii) the at-risk equity holders do not have the normal characteristics of a controlling financial interest. A controlling financial interest in a VIE is present when an enterprise has one or more variable interests that have both (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The enterprise with a controlling financial interest is the primary beneficiary and consolidates the VIE.

Voting interest entities lack one or more of the characteristics of a VIE. The usual condition for a controlling financial interest is ownership of a majority voting interest for a corporation or a majority of kick-out or participating rights for a limited partnership.

When the Company does not have a controlling financial interest in an entity but exerts significant influence over the entity’s operating and financial policies (generally defined as owning a voting or economic interest of between 20% to 50%), the Company’s investment is accounted for under the equity method of accounting. If the Company does not have a controlling financial interest in, or exert significant influence over, an entity, the Company accounts for its investment at fair value, if the fair value option was elected, or at cost.

The Company has an investment in 1347 Property Insurance Holdings, Inc., made through FGI 1347 Holdings, LP, a consolidated VIE.

Inventories

Inventories are stated at the lower of cost (determined by the average cost method) or net realizable value. Freight costs are classified as a component of cost of products in the accompanying consolidated statements of operations.

The allowance for slow-moving, excess, or obsolete inventory is used to state the Company’s inventories at the lower of cost and net realizable value. Because the amount of inventory that will actually be recouped through sales cannot be known with certainty at any particular time, the Company relies on past sales experience, future sales forecasts, and its strategic business plans. Generally, in analyzing inventory levels, inventory is classified as having been used or unused during the past year. The Company then establishes an allowance based upon several factors, including, but not limited to, business forecasts, inventory quantities and historic usage profile.

Supplemental to the aforementioned analysis, specific inventory items are reviewed individually by management. Based on the review, considering business levels, future prospects, new products and technology changes, management, using its business judgment, may adjust the valuation of specific inventory items to reflect an accurate valuation. Management also performs a determination of net realizable value for all finished goods with a selling price below cost. For all such items, the inventory is valued at not more than the selling price less cost, if any, to sell.

Property, Plant and Equipment

Property, plant and equipment is carried at cost. Expenditures for maintenance, repairs and minor renewals are expensed as incurred. When properties are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is reflected in operations for the period.

Depreciation and amortization are generally computed on the straight-line method using lives of 3 to 10 years for machinery and equipment and 5 to 8 years for leasehold improvements.

Impairment of Long-Lived Assets

Management regularly reviews long-lived assets and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds their fair value, which considers the discounted future net cash flows. No long-lived assets were considered impaired at December 31, 2018 and 2017.

Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.

Allowance for Doubtful Accounts

The Company records an allowance for doubtful accounts based on specifically identified amounts that the Company believes to be uncollectible. The Company also records an additional allowance based on certain percentages of the Company’s aged receivables, which are determined based on historical experience and the Company’s assessment of the general financial conditions affecting the Company’s customer base. If the Company’s actual collections experience changes, revisions to the Company’s allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. Based on the information available, management believes the allowance for doubtful accounts as of December 31, 2018 and 2017 is adequate.

Revenue Recognition

Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” and the additional related ASUs (“ASC 606”), which replaces existing revenue guidance and outlines a single set of comprehensive principles for recognizing revenue under accounting principles generally accepted in the United States of America (“GAAP”). The Company elected the modified retrospective method upon adoption, with no impact to the opening retained earnings or revenue reported. These standards provide guidance on recognizing revenue, including a five-step method to determine when revenue recognition is appropriate:

Step 1: Identify the contract with the customer;

Step 2: Identify the performance obligations in the contract;

Step 3: Determine the transaction price;

Step 4: Allocate the transaction price to the performance obligations; and

Step 5: Recognize revenue as the Company satisfies a performance obligation.

ASC 606 provides that sales revenue is recognized when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The Company generally satisfies performance obligations upon shipment of the product or service to the customer. This is consistent with the time in which the customer obtains control of the product or service. For extended warranties, sales revenue associated with the warranty is deferred at the time of sale and later recognized on a straight-line basis over the extended warranty period. Some contracts include installation services, which are completed in a short period of time and the revenue is recognized when the installation is complete. Customary payment terms are granted to customers, based on credit evaluations. Currently, the Company does not have any contracts where revenue is recognized, but the customer payment is contingent on a future event.

The Company periodically reviews its revenue recognition procedures to assure that such procedures are in accordance with GAAP. Surcharges collected on certain sales to government customers and remitted to governmental agencies are not included in revenues or in costs and expenses.

Income Taxes

The Company accounts for income taxes using the asset and liability method specified by GAAP. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply in the period in which the deferred tax asset or liability is expected to be realized. The effect of changes in net deferred tax assets and liabilities is recognized on the Company’s consolidated balance sheets and consolidated statements of operations in the period in which the change is recognized. Valuation allowances are provided to the extent that impairment of tax assets is more likely than not. In determining whether a tax asset is realizable, the Company considers, among other things, estimates of future earnings based on information currently available, current and anticipated customers, contracts and new product introductions, as well as recent operating results during 2018 and 2017 and certain tax planning strategies. If the Company fails to achieve the future results anticipated in the calculation and valuation of net deferred tax assets, the Company may be required to adjust the valuation allowance related to its deferred tax assets in the future.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “2017 Tax Act”). The 2017 Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35% to 21%; (2) eliminating the corporate alternative minimum tax (“AMT”) and changing how existing AMT credits can be realized; and (3) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017.

In connection with the Company’s initial analysis of the impact of the 2017 Tax Act, the Company recorded a discrete net tax expense of $665 in the year ended December 31, 2017 for the effect of the corporate rate reduction, which was finalized as of December 31, 2018. The net tax expense primarily relates to a reduction in the deferred tax assets of $1,524 and a reduction in the deferred tax liability related to unrealized gain on available-for-sale securities of $(859).

Concentration of Credit Risk

The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. At December 31, 2018 and 2017, accounts receivable from governmental customers were approximately $3,331 and $2,663, respectively. Generally, receivables are due within 30 days. Credit losses relating to customers have been consistently within management’s expectations.

The Company primarily maintains cash balances at one financial institution. Accounts are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250. From time to time, the Company has had cash in financial institutions in excess of federally insured limits. As of December 31, 2018, the Company had cash and cash equivalents in excess of FDIC limits of $11,050.

Manufacturing and Raw Materials

The Company relies upon a limited number of manufacturers to produce its products and on a limited number of component suppliers. Some of these manufacturers and suppliers are in other countries. Approximately 66.8% of the Company’s material, subassembly and product procurements in 2018 were sourced internationally, of which approximately 60.0% were sourced from two suppliers. For 2017, approximately 65.7% of the Company’s material, subassembly and product procurements were sourced internationally, of which approximately 61.6% were sourced from three suppliers. Purchase orders denominated in U.S. dollars are placed with these suppliers from time to time and there are no guaranteed supply arrangements or commitments.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of sales and expenses during the reporting period. Significant estimates include accounts receivable allowances, inventory obsolescence allowance, warranty allowance, and income tax accruals. Actual results could differ from those estimates.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, trade accounts receivable, available-for-sale securities, investment in securities, accounts payable, accrued expenses and other liabilities. As of December 31, 2018 and 2017, the carrying amount of cash and cash equivalents, trade accounts receivable, accounts payable, accrued expenses and other liabilities approximated their respective fair value due to the short-term nature and maturity of these instruments. The Company uses observable market data or assumptions (Level 1 inputs, as defined in accounting guidance) that it believes market participants would use in pricing the available-for-sale securities and investment in securities. There were no sales of available-for-sale securities or investment in securities, as a result of an other-than-temporary impairment of the available-for-sale securities. There were no transfers of available-for-sale securities or investments in securities between Level 1 and Level 2 during the years ended December 31, 2018 and 2017.

Available-For-Sale Securities

Investments reported on the December 31, 2017 balance sheet consisted of marketable equity securities of a publicly held company. As of December 31, 2017, the investment cost was $2,402. On January 1, 2018, the Company adopted ASU 2016-01 “Financial Instruments,” which amended the guidance in GAAP regarding the classification and measurement of financial instruments. Changes to the prior guidance primarily affected the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. Upon its adoption, the Company applied the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance was effective. On January 1, 2018, the Company recognized approximately $4,300 of net unrealized gain in its accumulated deficit balance. During the first quarter of 2018, the Company sold 1,317,503 shares of Iteris, Inc. (Nasdaq: ITI), which cost $2,402, for approximately $8,335 of proceeds and reported a loss on the sale of approximately $849.

Shipping and Handling Costs

Shipping and handling costs are classified as a part of cost of products in the accompanying consolidated statements of operations for the years ended December 31, 2018 and 2017. Amounts billed to a customer, if any, for shipping and handling are reported as revenue.

Advertising and Promotion Costs

The cost for advertising and promotion is expensed as incurred. Advertising and promotion expenses are classified as part of selling, general and administrative (“SG&A”) expenses in the accompanying consolidated statements of operations. For the years ended December 31, 2018 and 2017, such expenses totaled $597 and $424, respectively.

Engineering, Research and Development Costs

Included in SG&A expenses for the years ended December 31, 2018 and 2017 are engineering, research and development costs of $7,768 and $5,000, respectively.

Share-Based Compensation

The Company accounts for share-based arrangements in accordance with GAAP, which requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award (with limited exceptions). That cost will be recognized over the period during which the employee is required to provide service in exchange for the award requisite service period (usually the vesting period). No compensation cost is recognized for equity instruments for which employees do not render the requisite service. Employee share purchase plans will not result in recognition of compensation cost if certain conditions are met.

Restricted Stock Units

On September 6, 2018, the Company granted to each non-employee director restricted stock units with a grant fair value of $20 per award (resulting in total aggregate grant-date fair value of $140), which will vest in five equal, annual installments beginning with the first anniversary of the grant date, subject to the director’s continued service through such date, provided that, if the director makes himself available and consents to be nominated by the Company for continued service as a director, but is not nominated for the Board for election by shareholders, other than for good reason, as determined by the Board in its discretion, then the restricted stock units shall vest in full as of the director’s last date of service as a director of the Company.

On June 4, 2018, the Company granted to each non-employee director restricted stock units with a grant fair value of $20 per award (resulting in total aggregate grant-date fair value of $140), which will vest on June 4, 2019, subject to continued service through such vesting date.

On June 15, 2017, the Company granted to each non-employee director restricted stock units with a grant fair value of $20 per award (resulting in total aggregate grant-date fair value of $140), which vested on June 15, 2018.

The Company recorded non-cash restricted stock unit compensation expense of $153 and $76 for the years ended December 31, 2018 and 2017, respectively.

Earnings (Loss) Per Share

Earnings (loss) per share amounts are computed and presented for all periods in accordance with GAAP.

Other Comprehensive Loss

Other comprehensive loss consists of net loss and unrealized gain on available-for-sale securities, net of taxes.

Product Warranty

The Company offers two-year warranties to its customers, depending on the specific product and terms of the customer purchase agreement. The Company’s typical warranties require it to repair and replace defective products during the warranty period at no cost to the customer. At the time the product revenue is recognized, the Company records a liability for estimated costs under its warranties. The costs are estimated based on historical experience. The Company periodically assesses the adequacy of its recorded liability for product warranties and adjusts the amount as necessary.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications had no impact on previously reported net loss for the year ended December 31, 2017.

Recently Adopted Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 on “Revenue from Contracts with Customers,” which provided for a single, principles-based model for revenue recognition and replaced the existing revenue recognition guidance. In August 2015, the FASB issued ASU 2015-14, which delayed the effective date of ASU 2014-09 by one year. The guidance became effective for annual and interim periods beginning on or after December 15, 2017, and replaced most existing revenue recognition guidance under GAAP when it became effective. This ASU required additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and estimates and changes in those estimates. It permitted the use of either a retrospective or cumulative effect transition method. The Company adopted ASU 2014-09 in the first quarter of 2018 and applied the modified retrospective approach. Because the Company’s primary source of revenues is from shipments of products, the adoption of ASU 2014-09 did not have a material impact on its consolidated financial statements. See Note 1, under “Revenue Recognition,” for additional information.

In January 2016, the FASB issued ASU 2016-01 “Financial Instruments,” which amended the guidance in GAAP on the classification and measurement of financial instruments. Changes to the previous guidance primarily affected the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The new standard became effective for fiscal years and interim periods beginning after December 15, 2017, and upon adoption, an entity was required to apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. On January 1, 2018, the Company adopted the new guidance and, consequently, the Company recognized approximately $4,300 of net unrealized gain in its accumulated deficit balance.

In August 2018, the FASB issued ASU 2018-15, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement) by providing guidance for determining when the arrangement includes a software license. The amendments in ASU 2018-15 align 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 (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in ASU 2018-15. The amendments in ASU 2018-15 will become effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period. The Company adopted the new guidance in the fourth quarter of 2018, with no material impact on its consolidated financial statements and related disclosures.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, “Leases,” which amends leasing guidance by requiring companies to recognize a right-of-use asset and a lease liability for all operating and capital (finance) leases with lease terms greater than twelve months. The lease liability will be equal to the present value of lease payments. The lease asset will be based on the lease liability, subject to adjustment, such as for initial direct costs. For income statement purposes, leases will continue to be classified as operating or capital (finance), with lease expense in both cases calculated substantially the same as under the prior leasing guidance. The updated guidance is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company expects this will result in the recognition of right-of-use assets and lease liabilities not currently recorded on the consolidated financial statements under existing accounting guidance. Based on the Company’s evaluation of all of its contractual arrangements, the Company expects that the adoption of ASU 2016-02 will have a significant impact on the Company’s consolidated financial statements. After the adoption, the Company will first report the operating lease right-of-use assets and lease liabilities as of March 31, 2019 based on our lease portfolio as of that date.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, “Disclosure Update and Simplification,” amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders’ equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders’ equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed. This final rule is effective for all filings made on or after November 5, 2018. Given the effective date and the proximity to most filers’ quarterly reports, the SEC is not objecting to filers deferring the presentation of interim changes in stockholders’ equity in their Forms 10-Q until the quarter that begins after the date of adoption, November 5, 2018. The Company intends to present interim changes in stockholders’ equity beginning with its quarterly report on Form 10-Q for the first quarter of 2019.

The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.
