Notes to Condensed Consolidated Financial Statements (Unaudited)

A. Subsidiaries of the Registrant

The LGL Group, Inc. (the “Company”), incorporated in 1928 under the laws of the State of Indiana and reincorporated under the laws of the State of Delaware in 2007, is a diversified holding company with subsidiaries engaged in the designing, manufacturing and marketing of highly-engineered, highreliability frequency and spectrum control products used to control the frequency or timing of signals in electronic circuits, and in the design of high performance Frequency and Time Reference Standards that form the basis for timing and synchronization in various applications.

As of March 31, 2019, the subsidiaries of the Company were as follows:

	Owned By The LGL Group, Inc.
M-tron Industries, Inc.		100.0	%
Piezo Technology, Inc.		100.0	%
Piezo Technology India Private Ltd.		99.9	%
M-tron Asia, LLC		100.0	%
M-tron Industries, Ltd.		100.0	%
GC Opportunities Ltd.		100.0	%
M-tron Services, Ltd.		100.0	%
Precise Time and Frequency, LLC		100.0	%
Lynch Systems, Inc.		100.0	%

The Company operates through its two principal subsidiaries, M-tron Industries, Inc. (“MtronPTI”), which includes the operations of Piezo Technology, Inc. (“PTI”) and M-tron Asia, LLC (“Mtron”), and Precise Time and Frequency, LLC (“PTF”). The Company operates in two identified segments. The first segment, the electronic components segment, is focused on the design and manufacture of highly-engineered, high reliability frequency and spectrum control products. These electronic components ensure reliability and security in aerospace and defense communications, low noise and base accuracy for laboratory instruments, and synchronous data transfers throughout the wireless and Internet infrastructure. The second segment, the electronic instruments segment, is focused on the design and manufacture of high performance Frequency and Time Reference Standards that form the basis for timing and synchronization in various applications. The Company has operations in Orlando, Florida, Yankton, South Dakota, Wakefield, Massachusetts and Noida, India and sales offices in Austin, Texas and Hong Kong.

B. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Rule 8-03 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2019.

This interim information should be read in conjunction with the audited consolidated financial statements and related notes thereto set forth in the Company's Annual Report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission (the “SEC”) on March 21, 2019. The accompanying unaudited condensed consolidated financial statements should also be read in conjunction with Management's Discussion and Analysis of Financial Condition and Results of Operations contained in this Quarterly Report on Form 10-Q.

Revenue Recognition

The Company recognizes revenue from the sale of its products in accordance with the criteria in Accounting Standards Codification (“ASC”) 606, Revenue From Contracts with Customers, which are:

Step 1: Identify the contract(s) with a 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 in the contract.

Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

The Company meets these conditions upon the Company’s satisfaction of the performance obligation, usually at the time of shipment to the customer, because control passes to the customer at that time. Our standard terms for customers are net due within 30 days, with a few exceptions, none regularly exceeding 60 days.

5

The Company provides disaggregated revenue details by segment in Note J – Segment Information, and geographic markets in Note K – Domestic and Foreign Revenues.

The Company offers a limited right of return and/or authorized price protection provisions in its agreements with certain electronic component distributors who resell the Company's products to original equipment manufacturers or electronic manufacturing services companies. As a result, the Company estimates and records a reserve for future returns and other charges against revenue at the time of shipment consistent with the terms of sale. The reserve is estimated based on historical experience with each respective distributor. These reserves and charges are immaterial as the Company does not have a history of significant price protection adjustments or returns. The Company provides a standard assurance warranty that does not create a performance obligation.

Practical Expedients:

- The Company applies the practical expedient for shipping and handling as fulfillment costs.

- The Company expenses sales commissions as sales and marketing expenses in the period they are incurred.

Other Comprehensive Income

Our comprehensive income for the three months ended March 31, 2019 and March 31, 2018 consisted entirely of net income. Therefore a consolidated statement of comprehensive income is not presented for the three months ended March 31, 2019 and March 31, 2018.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842)”, to require lessees to recognize all leases, with limited exceptions, on the balance sheet. The objective of this update is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Subsequently, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842”, ASU 2018-11, “Targeted Improvements”, ASU 2018-20, “Narrow-Scope Improvements for Lessors”, and ASU 2019-01, “Codification Improvements”, to clarify and amend the guidance in ASU 2016-02. The Company adopted the ASUs effective January 1, 2019 resulting in the addition of $142,000 to other assets, with an equal offset to liabilities. The adoption of the ASUs did not have a material impact on the condensed consolidated statement of operations or the condensed consolidated statement of cash flows.

C. Related Party Transactions

Certain balances held and invested in various mutual funds are managed by a related entity (the "Fund Manager"), which is related through a director who is also a greater than 10% stockholder and currently serves as an executive officer of the Fund Manager. The brokerage and fund transactions in 2019 and 2018 were directed solely at the discretion of the Company’s management.

As of March 31, 2019, the balance with the Fund Manager totaled $17,615,000, including $8,775,000 which is classified within cash and cash equivalents on the accompanying unaudited consolidated balance sheets, and $8,840,000 which is classified within marketable securities on the accompanying unaudited consolidated balance sheets. Amounts invested generated $146,000 of realized and unrealized investment income during 2019 that is included within other income, net on the accompanying unaudited consolidated statements of operations. Fund management fees are anticipated to average less than 0.35% of the asset balances under management on an annual basis.

As of December 31, 2018, the balance with the Fund Manager totaled $16,270,000, including $12,506,000 which is classified within cash and cash equivalents on the accompanying unaudited consolidated balance sheets, and $3,764,000 which is classified as marketable securities on the accompanying unaudited consolidated balance sheets.

D. Fair Value Measurements

Fair value is defined as 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. Fair value guidance identifies three primary valuation techniques: the market approach, the income approach and the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts such as cash flows or earnings, to a single present amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to observable inputs such as quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The maximization of observable inputs and the minimization of the use of unobservable inputs are required.

Classification within the fair value hierarchy is based upon the objectivity of the inputs that are significant to the valuation of an asset or liability as of the measurement date. The three levels within the fair value hierarchy are characterized as follows:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 - Unobservable inputs for the asset or liability for which there is little, if any, market activity for the asset or liability at the measurement date. Unobservable inputs reflect the Company's own assumptions about what market participants would use to price the asset or liability. These inputs may include internally developed pricing models, discounted cash flow methodologies, as well as instruments for which the fair value determination requires significant management judgment.

Assets

To estimate the market value of its marketable securities, the Company obtains current market pricing from quoted market sources or uses pricing for identical securities. Assets measured at fair value on a recurring basis are summarized below (in thousands).

	Level 1		Level 2		Level 3		Total at March 31, 2019
Marketable Equity Security	$	12	$	—	$	—	$	12
Equity Mutual Fund		—		8,840		—		8,840
U.S. Treasury Mutual Fund		8,775		—		—		8,775
	$	8,787	$	8,840	$	—	$	17,627

	Level 1		Level 2		Level 3		Total at December 31, 2018
Marketable Equity Security	$	11	$	—	$	—	$	11
Equity Mutual Fund		—		3,764		—		3,764
U.S. Treasury Mutual Fund		12,506		—		—		12,506
	$	12,517	$	3,764	$	—	$	16,281

There were no transfers from level 2 to level 3 during the periods presented. There were no level 3 assets as of March 31, 2019 or December 31, 2018. The Company also has assets that may be subject to measurement at fair value on a non-recurring basis, including goodwill and intangible assets, and other long-lived assets. There were no liabilities subject to fair value on a non-recurring or recurring basis as of March 31, 2019 or December 31, 2018.

The Company reviews goodwill and the carrying value of long-lived assets at least annually or whenever events and circumstances indicate that the carrying amounts of the assets may not be recoverable. If it is determined that the assets are impaired, the carrying value would be reduced to estimated fair value.

7

E.Inventories

Inventories are valued at the lower of cost or net realizable value using the FIFO (first-in, first-out) method. The Company reduces the value of its inventories to net realizable value when the net realizable value is believed to be less than the cost of the item. The inventory reserve for obsolescence as of March 31, 2019 and December 31, 2018 was $1,341,000 and $1,266,000, respectively.

Inventories are comprised of the following (in thousands):

	March 31, 2019		December 31, 2018
Raw materials	$	2,247	$	1,719
Work in process		2,034		1,807
Finished goods		892		940
Total Inventories, net	$	5,173	$	4,466

F. Intangible Assets

Intangible assets are recorded at cost less accumulated amortization which is included in engineering, selling and administrative expenses in the accompanying unaudited condensed consolidated statements of operations. Amortization is computed for financial reporting purposes using the straight-line method over the estimated useful lives of the assets, which range up to 10 years. The intangible assets consist of intellectual property and goodwill. The net carrying value of the amortizable intangible assets was $418,000 and $437,000 as of March 31, 2019 and December 31, 2018, respectively. Goodwill, which is not amortizable, was $40,000 as of both March 31, 2019 and December 31, 2018.

G. Stock-Based Compensation

The Company measures the cost of employee services in exchange for an award of equity instruments based on the grant-date fair value of the award and recognizes the cost over the requisite service period, typically the vesting period.

The Company estimates the fair value of stock options on the grant date using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. There is no expected dividend rate. Historical Company information was the basis for the expected volatility assumption as the Company believes that the historical volatility is indicative of expected volatility over the life of the option. The risk-free interest rate is based on the U.S. Treasury zero-coupon rates with a remaining term equal to the expected term of the option.

Compensation expense related to share-based compensation is recognized over the applicable vesting periods. As of March 31, 2019, there was approximately $25,000 of total unrecognized compensation expense related to unvested share-based compensation arrangements that will be recognized over a weighted average period of 1.3 years.

H. Earnings Per Share

The Company computes earnings per share in accordance with ASC 260, Earnings Per Share. Basic earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding during the period. Diluted earnings per share adjusts basic earnings per share for the effects of stock options and other potentially dilutive financial instruments, only in the periods in which the effects are dilutive. The dilutive effect of share-based awards is reflected in earnings per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense required under the Compensation – Stock Compensation Topic of the ASC.

For the three months ended March 31, 2019 and 2018, there were options to purchase 6,067 shares and 9,541 shares, respectively, of the Company's common stock and for the three months ended March 31, 2018, there were warrants to purchase 519,241 shares of common stock that were excluded from the diluted earnings per share computation because the impact of the assumed exercise of such stock options or warrants would have been anti-dilutive during the respective periods.

The following table reconciles basic weighted average shares outstanding to diluted weighted average shares outstanding for the three months ended March 31, 2019 and 2018:

	Three Months Ended March 31,
	2019		2018
Weighted average shares outstanding - basic		4,838,568		4,696,415
Effect of diluted securities		121,068		109,781
Weighted average shares outstanding - diluted		4,959,636		4,806,196

I. Stockholders’ Equity

Share Repurchase Program

On August 29, 2011, the Company’s board of directors (the “Board”) authorized the Company to repurchase up to 100,000 shares of its common stock in accordance with applicable securities laws. This authorization increased the total number of shares authorized and available for repurchase under the Company's existing share repurchase program to 540,000 shares, at such times, amounts and prices as the Company shall deem appropriate. As of March 31, 2019, the Company had repurchased a total of 81,584 shares of common stock at a cost of $580,000, which shares are currently held in treasury.

J. Segment Information

The Company has two reportable business segments from operations: electronic components, which includes all products manufactured and sold by MtronPTI, and electronic instruments, which includes all products manufactured and sold by PTF. The Company's foreign operations in Hong Kong and India are subsidiaries of MtronPTI. The following table sets forth activity broken down by reportable business segment (in thousands):

	Three Months Ended March 31,
	2019			2018
Revenues from Operations
Electronic components	$	6,331		$	5,731

All other foreign countries		617		634
Total foreign revenues	$	1,709	$	1,434
Total domestic revenue	$	4,923	$	4,511

The Company allocates its foreign revenue based on the customer's ship-to location.

L. Commitments and Contingencies

In the ordinary course of business, the Company and its subsidiaries may become defendants in certain product liability, patent infringement, worker claims and other litigation. The Company records a liability when it is probable that a loss has been incurred and the amount is reasonably estimable.

Results of Operations

Three months ended March 31, 2019 compared to three months ended March 31, 2018

Consolidated Revenues, Gross Margin and Backlog

Total revenues for the three months ended March 31, 2019 were $6,632,000, an increase of $687,000, or 11.6%, from revenues of $5,945,000 for the three months ended March 31, 2018. Revenue growth was due primarily to increased filter sales of $345,000, and increased sales of $171,000 from our time and frequency products, along with increased sales of purchased products of $162,000.

Consolidated gross margin, which is consolidated revenues less manufacturing cost of sales, as a percentage of revenues decreased slightly to 36.4% for the three months ended March 31, 2019, from 37.5% for the three months ended March 31, 2018. The decrease reflects a shift in our product mix shipped during the quarter. The Company continues to execute its long-term strategic shift toward higher margin products, but there are still fluctuations of product mix in the short-term.

As of March 31, 2019, our order backlog was $21,301,000, which is an increase of 60.2% compared to the backlog of $13,294,000 as of March 31, 2018. The increase is indicative of a favorable market and LGL’s stronger execution in delivering design wins and building backlog. The backlog of unfilled orders includes amounts based on signed contracts as well as agreed letters of intent, which we have determined are firm orders likely to be fulfilled in the next 12 months.

Order backlog is adjusted quarterly to reflect project cancellations, deferrals, revised project scope and cost, and sales of subsidiaries, if any. We expect to fill our entire order backlog within the next twelve months, but cannot provide assurances as to what portion of the order backlog will be fulfilled in a given year.

Stock-Based Compensation

For the three months ended March 31, 2019 and 2018, stock-based compensation expense was $6,000 and $7,000, respectively. Compensation expense related to stock-based compensation is recognized over the applicable vesting periods. As of March 31, 2019, there was approximately $25,000 of total unrecognized compensation expense related to unvested stock-based compensation arrangements.

10

Operating Income

Operating income of $434,000 for the three months ended March 31, 2019 was an improvement of $276,000 from operating income of $158,000 for the three months ended March 31, 2018. This was primarily due to the increase in revenues, net of the reduction in gross margin from the changes in product mix noted above.

Other Income, Net

For the three months ended March 31, 2019, other income, net was $153,000 compared to $24,000 for the three months ended March 31, 2018. The current period other income, net consists of $146,000 gain from our investment portfolio, along with foreign currency translation gains from settled transactions of $7,000. The prior period other income, net includes a $16,000 gain from our investment portfolio and $4,000 from a recovery on a previously written down note receivable, along with foreign currency translation gains from settled transactions of $4,000.

Income Tax Provision

We recorded a tax provision of $6,000 and $1,000 for the three months ended March 31, 2019 and 2018, respectively. The increase resulted primarily from income in our foreign subsidiaries.

Based on our assessment of the uncertainty surrounding the realization of the favorable tax attributes in future tax returns in accordance with the provisions of ASC 740, Income Taxes, we have determined that it is more likely than not that certain deferred tax assets generated from foreign net operating losses (“NOLs”) can be utilized in the foreseeable future and a valuation allowance for these assets is not required. We also determined that a full valuation against the remaining U.S. net deferred tax assets is required and have recorded a valuation allowance to reduce deferred tax assets to the amount that is more likely than not to be realized.

The Company periodically undertakes a review of its valuation allowance and it evaluates all positive and negative factors that may affect whether it is more probable than not that the Company would realize its future tax benefits. As positive factors continue to be present given our recent economic performance, the potential result would be a full or partial release of the valuation allowance on the deferred tax asset recognized in prior periods. At March 31, 2019, the balance in the valuation allowance was approximately $4.9 million. Any release of the valuation allowance would be recognized in the statements of operations. The balance of the deferred tax asset was approximately $5 million and $5.2 million as of March 31, 2019 and December 31, 2018, with a related valuation allowance of $4.9 million and $5.1 million, respectively.

Net Income

Net income for the three months ended March 31, 2019 was $582,000 compared to $193,000 for the three months ended March 31, 2018 due to the factors noted above. Basic and diluted net income per share for the three months ended March 31, 2019 and 2018 was $0.12 and $0.04, respectively.

Liquidity and Capital Resources

As of March 31, 2019 and December 31, 2018, cash and cash equivalents were $10,298,000 and $15,508,000, respectively. In the first quarter of 2019, we invested $5,000,000 in an equity mutual fund, which is classified as marketable securities on our consolidated balance sheets.

Cash provided by operating activities was $122,000 and $158,000 for the three months ended March 31, 2019 and 2018, respectively. The $36,000 decrease was due primarily to a year-over-year increase in net income of $389,000, offset by a year-over-year change in working capital accounts of $(380,000), and decreases in non-cash adjustments for gain on marketable securities of $(65,000).

Cash used in investing activities for the three months ended March 31, 2019 and 2018 was $5,403,000 and $172,000, respectively. The increase in the use of cash was primarily due to the purchase of $5,000,000 in marketable securities in the first quarter, and $231,000 in increased capital expenditures.

For the three months ended March 31, 2019, cash provided by financing activities represented $71,000 received by the Company for the exercise of stock options. For the three months ended March 31, 2018, financing activities represented $22,000 received by the company for the exercise of stock options.

As of March 31, 2019, our consolidated working capital was $24,880,000 compared to $24,633,000 as of December 31, 2018. As of March 31, 2019, we had current assets of $29,017,000, current liabilities of $4,137,000 and a ratio of current assets to current liabilities of 7.01 to 1.00. As of December 31, 2018, we had current assets of $27,385,000, current liabilities of $2,752,000 and a ratio of current assets to current liabilities of 9.95 to 1.00. Management continues to focus on efficiently managing working capital requirements to match operating activity levels, and will seek to deploy the Company’s working capital where it will generate the greatest returns.

We believe that existing cash and cash equivalents and cash generated from operations will be sufficient to meet our ongoing working capital and capital expenditure requirements for the next 12 months from the date of this filing.

11

Our Board has adhered to a practice of not paying cash dividends.This policy takes into account our long-term growth objectives, including our anticipated investments for organic growth, potential technology acquisitions or other strategic ventures, and stockholders' desire for capital appreciation of their holdings.No cash dividends have been paid to the Company's stockholders since January 30, 1989, and none are expected to be paid for the foreseeable future.

Critical Accounting Policies

Our accounting policies and unaudited condensed consolidated financial statements have been established to conform with GAAP. The preparation of financial statements in conformity with GAAP requires us to use judgment in the application of accounting policies, including making estimates and assumptions. These judgments 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. We believe we have made these estimates and assumptions in an appropriate manner and in a way that accurately reflects our financial condition. We continually test and evaluate these estimates and assumptions using historical knowledge of the business, as well as other factors, to ensure that they are reasonable for reporting purposes. However, actual results may differ from these estimates and assumptions. We believe that the accounting policies related to the following accounts or activities are those that are most critical to the portrayal of our financial condition and results of operations and require the more significant judgments and estimates:

• Revenue recognition;

• Accounts receivable allowance;

• Inventory valuation;

• Intangible assets;

• Income taxes; and

• Segment information.

There have been no significant changes to our critical accounting policies from those described in Note A – Accounting and Reporting Policies to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Item 3.Quantitative and Qualitative Disclosures About Market Risk.

Not applicable.

Item 4.Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms, and that such information is accumulated and communicated to us, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and we necessarily were required to apply our judgment in evaluating whether the benefits of the controls and procedures that we adopt outweigh their costs.

As required by Rules 13a-15(b) and 15d-15(b) of the Exchange Act, an evaluation as of March 31, 2019 was conducted under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures, as of March 31, 2019, were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal controls over financial reporting during the three months ended March 31, 2019, or in other factors that could significantly affect these controls, that materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Basis of Presentation

B. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Rule 8-03 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2019.

This interim information should be read in conjunction with the audited consolidated financial statements and related notes thereto set forth in the Company's Annual Report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission (the “SEC”) on March 21, 2019. The accompanying unaudited condensed consolidated financial statements should also be read in conjunction with Management's Discussion and Analysis of Financial Condition and Results of Operations contained in this Quarterly Report on Form 10-Q.

Revenue Recognition

The Company recognizes revenue from the sale of its products in accordance with the criteria in Accounting Standards Codification (“ASC”) 606, Revenue From Contracts with Customers, which are:

Step 1: Identify the contract(s) with a 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 in the contract.

Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

The Company meets these conditions upon the Company’s satisfaction of the performance obligation, usually at the time of shipment to the customer, because control passes to the customer at that time. Our standard terms for customers are net due within 30 days, with a few exceptions, none regularly exceeding 60 days.

The Company provides disaggregated revenue details by segment in Note J – Segment Information, and geographic markets in Note K – Domestic and Foreign Revenues.

The Company offers a limited right of return and/or authorized price protection provisions in its agreements with certain electronic component distributors who resell the Company's products to original equipment manufacturers or electronic manufacturing services companies. As a result, the Company estimates and records a reserve for future returns and other charges against revenue at the time of shipment consistent with the terms of sale. The reserve is estimated based on historical experience with each respective distributor. These reserves and charges are immaterial as the Company does not have a history of significant price protection adjustments or returns. The Company provides a standard assurance warranty that does not create a performance obligation.

Practical Expedients:

- The Company applies the practical expedient for shipping and handling as fulfillment costs.

- The Company expenses sales commissions as sales and marketing expenses in the period they are incurred.

Other Comprehensive Income

Our comprehensive income for the three months ended March 31, 2019 and March 31, 2018 consisted entirely of net income. Therefore a consolidated statement of comprehensive income is not presented for the three months ended March 31, 2019 and March 31, 2018.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842)”, to require lessees to recognize all leases, with limited exceptions, on the balance sheet. The objective of this update is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Subsequently, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842”, ASU 2018-11, “Targeted Improvements”, ASU 2018-20, “Narrow-Scope Improvements for Lessors”, and ASU 2019-01, “Codification Improvements”, to clarify and amend the guidance in ASU 2016-02. The Company adopted the ASUs effective January 1, 2019 resulting in the addition of $142,000 to other assets, with an equal offset to liabilities. The adoption of the ASUs did not have a material impact on the condensed consolidated statement of operations or the condensed consolidated statement of cash flows.

Fair Value Disclosures [Abstract]

Fair Value Measurements

D. Fair Value Measurements

Fair value is defined as 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. Fair value guidance identifies three primary valuation techniques: the market approach, the income approach and the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts such as cash flows or earnings, to a single present amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to observable inputs such as quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The maximization of observable inputs and the minimization of the use of unobservable inputs are required.

Classification within the fair value hierarchy is based upon the objectivity of the inputs that are significant to the valuation of an asset or liability as of the measurement date. The three levels within the fair value hierarchy are characterized as follows:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 - Unobservable inputs for the asset or liability for which there is little, if any, market activity for the asset or liability at the measurement date. Unobservable inputs reflect the Company's own assumptions about what market participants would use to price the asset or liability. These inputs may include internally developed pricing models, discounted cash flow methodologies, as well as instruments for which the fair value determination requires significant management judgment.

Assets

To estimate the market value of its marketable securities, the Company obtains current market pricing from quoted market sources or uses pricing for identical securities. Assets measured at fair value on a recurring basis are summarized below (in thousands).

	Level 1		Level 2		Level 3		Total at March 31, 2019
Marketable Equity Security	$	12	$	—	$	—	$	12

U.S. Treasury Mutual Fund		12,506		—		—		12,506
	$	12,517	$	3,764	$	—	$	16,281

There were no transfers from level 2 to level 3 during the periods presented. There were no level 3 assets as of March 31, 2019 or December 31, 2018. The Company also has assets that may be subject to measurement at fair value on a non-recurring basis, including goodwill and intangible assets, and other long-lived assets. There were no liabilities subject to fair value on a non-recurring or recurring basis as of March 31, 2019 or December 31, 2018.

The Company reviews goodwill and the carrying value of long-lived assets at least annually or whenever events and circumstances indicate that the carrying amounts of the assets may not be recoverable. If it is determined that the assets are impaired, the carrying value would be reduced to estimated fair value.

F. Intangible Assets

Intangible assets are recorded at cost less accumulated amortization which is included in engineering, selling and administrative expenses in the accompanying unaudited condensed consolidated statements of operations. Amortization is computed for financial reporting purposes using the straight-line method over the estimated useful lives of the assets, which range up to 10 years. The intangible assets consist of intellectual property and goodwill. The net carrying value of the amortizable intangible assets was $418,000 and $437,000 as of March 31, 2019 and December 31, 2018, respectively. Goodwill, which is not amortizable, was $40,000 as of both March 31, 2019 and December 31, 2018.

Stock-Based Compensation

G. Stock-Based Compensation

The Company measures the cost of employee services in exchange for an award of equity instruments based on the grant-date fair value of the award and recognizes the cost over the requisite service period, typically the vesting period.

The Company estimates the fair value of stock options on the grant date using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. There is no expected dividend rate. Historical Company information was the basis for the expected volatility assumption as the Company believes that the historical volatility is indicative of expected volatility over the life of the option. The risk-free interest rate is based on the U.S. Treasury zero-coupon rates with a remaining term equal to the expected term of the option.

Compensation expense related to share-based compensation is recognized over the applicable vesting periods. As of March 31, 2019, there was approximately $25,000 of total unrecognized compensation expense related to unvested share-based compensation arrangements that will be recognized over a weighted average period of 1.3 years.

Earnings Per Share

H. Earnings Per Share

The Company computes earnings per share in accordance with ASC 260, Earnings Per Share. Basic earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding during the period. Diluted earnings per share adjusts basic earnings per share for the effects of stock options and other potentially dilutive financial instruments, only in the periods in which the effects are dilutive. The dilutive effect of share-based awards is reflected in earnings per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense required under the Compensation – Stock Compensation Topic of the ASC.

For the three months ended March 31, 2019 and 2018, there were options to purchase 6,067 shares and 9,541 shares, respectively, of the Company's common stock and for the three months ended March 31, 2018, there were warrants to purchase 519,241 shares of common stock that were excluded from the diluted earnings per share computation because the impact of the assumed exercise of such stock options or warrants would have been anti-dilutive during the respective periods.

The following table reconciles basic weighted average shares outstanding to diluted weighted average shares outstanding for the three months ended March 31, 2019 and 2018:
