The condensed consolidated balance sheet as of SeptemberJune 30, 2018,2019, the condensed consolidated statements of income and comprehensive incomeoperations for the three and ninesix months ended SeptemberJune 30, 20182019 and 20172018, and the condensed consolidated statements of cash flows for the ninesix months ended SeptemberJune 30, 20182019 and 20172018 have been prepared by BK Technologies Inc.Corporation (the “Company” or “we”), and are unaudited. On March 28, 2019, BK Technologies, Inc., the predecessor of BK Technologies Corporation, implemented a holding company reorganization, which resulted in BK Technologies Corporation becoming the direct parent company of, and the successor issuer to, BK Technologies, Inc. For the purpose of this report, references to “we” or the “Company” or its management or business at any period prior to the holding company reorganization (March 28, 2019) refer to those of BK Technologies, Inc. as the predecessor company and its subsidiaries and thereafter to those of BK Technologies Corporation and its subsidiaries, except as otherwise specified or to the extent the context otherwise indicates. In the opinion of management, all adjustments, which include normal recurring adjustments, necessary for a fair presentation have been made. All intercompany transactions and balances have been eliminated in consolidation. The condensed consolidated balance sheet at December 31, 20172018 has been derived from the Company’s audited consolidated financial statements at that date.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. It is suggested that these condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017,2018, as filed with the Securities and Exchange Commission (“SEC”). The results of operations for the three and ninesix months ended SeptemberJune 30, 20182019 are not necessarily indicative of the operating results for a full year.

Effective January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, and the additional related ASUs (ASC “606”(“ASC 606”), which replacesreplaced existing revenue guidance and outlines a single set of comprehensive principles for recognizing revenue under U.S. 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.appropriate:

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.

The Company’s financial instruments consist of cash and cash equivalents, trade accounts receivable, investment in securities, accounts payable, accrued expenses and other liabilities. As of SeptemberJune 30, 20182019 and December 31, 2017,2018, 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.

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 Accounting Standards Update (“ASU”)ASU 2016-01 “Financial Instruments,” which amended the guidance in U.S. 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 sales of approximately $849.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 “Revenue from Contracts with Customers,” which provided for a single, principles-based model for revenue recognition and replaced the existing revenue recognition guidance, became effective for annual and interim periods beginning on or after December 15, 2017, and replaced most existing revenue recognition guidance under U.S. GAAP. This ASU requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgements and estimates and changes in those estimates. It permits the use of either a modified 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 this new guidance did not have any impact on its consolidated financial statements and related disclosures. See Note 1 for additional information.

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 became 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 permitted deferring the presentation of interim changes in stockholders’ equity in Forms 10-Q until the quarter that began after the date of adoption, November 5, 2018. The Company adopted this rule in the first quarter of 2019, and its adoption did not have a material impact on its retained earnings, asconsolidated financial statements. Note 7 (Stockholders’ Equity) of the Company reclassified approximately $4,300 of unrealized gain on investment securities that was previously classifiedNotes to these condensed consolidated financial statements summarizes changes in other comprehensive income.stockholders’ equity.

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.

Pursuant to the Company’s capital return program, on September 6, 2018, the Company’s Board of Directors declared a quarterly dividend of $0.02 per share of the Company’s common stock on June 10, 2019 to stockholders of record as of OctoberJuly 1, 2018.2019.

The allowance for doubtful accounts on trade receivables was approximately $50 on gross trade receivables of $7,457$5,143 and $5,574$5,771 at SeptemberJune 30, 20182019 and December 31, 2017,2018, respectively. This allowance is used to state trade receivables at a net realizable value or the amount that the Company estimates will be collected of the Company’s gross trade receivables.

The components of inventories, net of allowances for slow-moving, excess or obsolete inventory, consist of the following:

Allowances for slow-moving, excess, or obsolete inventory are used to state the Company’s inventories at the lower of cost or net realizable value. The allowances were approximately $758$678 at SeptemberJune 30, 2018,2019, compared with approximately $789$629 at December 31, 2017.2018.

IncomeThe Company recorded an income tax expense totalingand benefit, respectively, of approximately $17$154 and $200 has been recorded$201 for the three and ninesix months ended SeptemberJune 30, 2018,2019, respectively, compared with $252an income tax expense of approximately $290 and $353,$183, respectively, for the same periods last year.

As of SeptemberJune 30, 2018 and December 31, 2017,2019, the Company’s net deferred tax assets totaled approximately $3,122 and $3,317, respectively,$3,659, and were primarily composed ofderived from research and development tax credits, accrued expenses and net operating loss carryforwards (“NOLs”) and research and development costs and tax credits.  As of September 30, 2018, these NOLs totaled approximately $5,216 for federal and $12,766 for state purposes, with expirations starting in 2018 through 2030..

In order to fully utilize the net deferred tax assets, the Company will need to generate sufficient taxable income in future years to utilize its NOLs prior to their expiration.years. The Company analyzesanalyzed all positive and negative evidence to determine if, based on the weight of available evidence, the Companyit is more likely than not to realize the benefit of the net deferred tax assets. The recognition of the net deferred tax assets and related tax benefits is based upon the Company’s conclusions regarding, among other considerations, estimates of future earnings based on information currently available and current and anticipated customers, contracts and product introductions, as well as historical operating results and certain tax planning strategies.

Based on management’sthe analysis of all available evidence, both positive and negative, the Company’s managementCompany has concluded that the Company does not haveit has the ability to generate sufficient taxable income in the necessary period to utilize the entire benefit for the deferred tax asset. Management estimated that as of September 30, 2018, it is more likely than not that approximately $83 of the Company’s deferred tax asset will not be realized due to the inability to generate sufficient Florida taxable income in the necessary period to fully utilize its Florida NOLs. The Company cannot presently estimate what, if any, changes to the valuation of its deferred tax assets may be deemed appropriate in the future. If the Company incurs future losses, it may be necessary to record additionala valuation allowance related to the deferred tax assets recognized as of SeptemberJune 30, 2018.

We continue to utilize contract manufacturing relationships for production efficiencies and to manage material and labor costs. We anticipate that our current contract manufacturing relationships or comparable alternatives will be available to us in the future. We may encounter product cost and competitive pricing pressures in the future. However, the extent of their impact on gross margins, if any, is uncertain.

We recorded an income tax expense of approximately $17,000 and $200,000, respectively,$154,000 for the three and nine months ended SeptemberJune 30, 2018,2019, compared with income tax expense of approximately $252,000 and $353,000, respectively,$290,000 for the same periodssecond quarter last year.

Our income tax provision is based on management’s estimate of the effective tax rate for the full year.  The tax provision in any period will be affected by, among other things, permanent, as well as temporary, differences in the deductibility of certain items, in addition to changes in tax legislation. As a result, we may experience significant fluctuations in the effective book tax rate (that is, tax expense divided by pre-tax book income) from period to period.  For 2018,2019, we generally expect our effective tax rate to decline comparedbe comparable to 2017, primarily due to the implementation of the Tax Cuts and Jobs Act enacted in December 2017, which, among other things, reduced the U.S. federal corporate tax rate from 35% to 21%.last year.

As of SeptemberJune 30, 2018,2019, our net deferred tax assets totaled approximately $3.1$3.7 million, and were primarily composed of NOLs.  These NOLs totaled approximately $5.2 million for federalderived from research and $12.7 million for state purposes, with expirations starting in 2018 through 2030.development tax credits and accrued expenses.

In order to fully utilize the net deferred tax assets, we will need to generate sufficient taxable income in future years to utilize our NOLs prior to their expiration.years. We analyze all positive and negative evidence to determine if, based on the weight of available evidence, we are more likely than not to realize the benefit of the net deferred tax assets. The recognition of the net deferred tax assets and related tax benefits is based upon our conclusions regarding, among other considerations, estimates of future earnings based on information currently available and current and anticipated customers, contracts and product introductions, as well as historical operating results and certain tax planning strategies.

Based on our analysis of all available evidence, both positive and negative, we have concluded that we do not have the ability to generate sufficient taxable income in the necessary period to utilize the entire benefit for the deferred tax asset. Management estimates that as of September 30, 2018, it is more likely than not that approximately $83,000 of the deferred tax asset will not be realized due to the inability to generate sufficient Florida taxable income in the necessary period to fully utilize the Florida NOLs. We cannot presently estimate what, if any, changes to the valuation of our deferred tax assets may be deemed appropriate in the future. If we incur future losses, it may be necessary to record additional valuation allowance related to the deferred tax assets recognized as of SeptemberJune 30, 2018.2019.

We haveOn March 28, 2019, BK Technologies, Inc., our wholly-owned subsidiary, and RELM Communications, Inc., a wholly-owned subsidiary of BK Technologies, Inc., entered into an Amended and Restated Loan and Security Agreement (the “Loan and Security Agreement”) with Silicon Valley Bank (“SVB”). The Loan and Security Agreement replaced BK Technologies, Inc.’s prior Loan and Security Agreement with SVB (the “Prior Agreement”) under which its secured revolving credit facility (the “Credit Facility”) was maintained.

Pursuant to the Loan and Security Agreement, the Credit Facility continues to provide BK Technologies, Inc. with Silicon Valley Bank witha maximum borrowing availability of $1.0 million, and aBK Technologies, Inc. continues to be subject to substantially the same customary borrowing terms and conditions under the Credit Facility as it was under the Prior Agreement, including the accuracy of representations and warranties, compliance with financial maintenance and restrictive covenants and the absence of events of default. Pursuant to the Loan and Security Agreement, payment of cash dividends, in the aggregate not to exceed $5.0 million during any twelve-month period, is permitted so long as an event of default does not exist at the time of such dividend and would not exist after giving effect to such dividend. Any borrowings under the Credit Facility will bear interest at the variable interest rate equal to 25 basis points above the Wall Street Journal prime rate. The maturity date of the Credit Facility has been extended to December 26, 2018. As2019.

 The financial maintenance covenants, required to be maintained at all times and tested quarterly (or, for the “Adjusted Quick Ratio” covenant, monthly, if any obligations are outstanding), include: (1) a ratio of September 30, 2018,“Quick Assets” to the sum of “Current Liabilities” plus outstanding borrowings to SVB to the extent not included in “Current Liabilities” minus the current portion of “Deferred Revenue” (all as defined in the Loan and Security Agreement) of at least 1.25:1.00; provided that “Net Cash” (defined as the datedifference between unrestricted cash on deposit with SVB minus any outstanding advances under the Credit Facility) is required to be at least $1.0 million; and (2) maximum “Total Leverage” (as defined in the Loan and Security Agreement) of this report, we wereno greater total consolidated “Indebtedness” than 3 times “Adjusted EBITDA” (all as defined in the Loan and Security Agreement). BK Technologies, Inc.’s obligations are collateralized by substantially all of its assets, principally accounts receivable and inventory.

 BK Technologies, Inc. was in compliance with all covenants under the loanLoan and security agreement,Security Agreement as amended, governing the revolving credit facility. For a description of such covenants and the other terms and conditions of the loan and security agreement, as amended, reference is made to Note 5 (Debt)date of our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

Our cash and cash equivalents balance at SeptemberJune 30, 20182019 was approximately $11.3$7.4 million.  We believe these funds combined with anticipated cash generated from operations and borrowing availability under our revolving credit facilityCredit Facility are sufficient to meet our working capital requirements for the foreseeable future. However, financial and economic conditions could limit our access to credit and impair our ability to raise capital, if needed, on acceptable terms or at all. We also face other risks that could impact our business, liquidity and financial condition. For a description of these risks, see “Item 1A. Risk Factors” set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

In response to the Securities and Exchange Commission’s financial reporting release, FR-60, Cautionary Advice Regarding Disclosure About Critical Accounting Policies, we have selected for disclosure our revenue recognition process and our accounting processes involving significant judgments, estimates and assumptions.  These processes affect our reported revenues and current assets and are, therefore, critical in assessing our financial and operating status.  We regularly evaluate these processes in preparing our financial statements.  The processes for revenue recognition, allowance for collection of trade receivables, allowance for excess or obsolete inventory, software development and income taxes involve certain assumptions and estimates that we believe to be reasonable under present facts and circumstances.  These estimates and assumptions, if incorrect, could adversely impact our operations and financial position. The Company adopted ASU No. 2014-09, "Revenue from Contracts with Customers", and all the related amendments (collectively “Topic 606”) in the first quarter of 2018 and applied the modified retrospective approach.  Under Topic 606, revenue is recognized when control of promised goods and services is transferred to customers, and the amount of revenue recognized reflects the consideration to which an entity expects to be entitled in exchange for the goods and services transferred.  The adoption of Topic 606 did not have, and is not expected to have, a material effect on the timing or amount of revenue recognized as compared with the Company’s previous revenue recognition practices because the Company’s primary source of revenues is from shipments of products.  

There were no other changes to our critical accounting policies during the quarter ended SeptemberJune 30, 2018,2019, as described in Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.
