Note 1. Basis of Presentation

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions and regulations of the Securities and Exchange Commission to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements.

This report should be read together with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, including the audited financial statements and footnotes therein.

Management believes that the unaudited financial statements include all adjustments, consisting of normal recurring accruals, necessary to fairly state the financial position and results of operations as of June 30, 2018 and for the three and six-month periods then ended in accordance with accounting principles generally accepted in the United States of America. The results of interim periods may not be indicative of results to be expected for the year.

Nature of Business

Electro-Sensors, Inc. manufactures and markets a complete line of monitoring and control systems for a variety of industrial machinery. The Company uses leading-edge technology to continuously improve its products and make them easier to use, with the goal of manufacturing the industry-preferred product for every market served. The Company sells these products through an internal sales staff, manufacturers’ representatives, and distributors to a wide variety of industries that use the products in a variety of applications to monitor process machinery operations. The Company markets its products to customers located throughout the United States, Canada, Latin America, Europe, and Asia.

Revenue Recognition

On January 1, 2018, the Company adopted Accounting Standards Codification (ASC) Revenue from Contracts with Customers and all related amendments (the Standard), for all contracts using the modified retrospective method. The Standard implements a five-step process for revenue recognition that focuses on transfer of control and defines a contract as “an agreement between two or more parties that creates legally enforceable rights and obligations." The adoption of the Standard did not materially impact the timing and measurement of revenue recognition. As a result, we did not recognize a cumulative effect adjustment to the opening balance of retained earnings.

At contract inception, the Company assesses the goods and services promised to a customer and identifies a performance obligation for each promised good or service that is distinct.In addition, the transaction price for each performance obligation is determined at contract inception.Our contracts, generally in the form of a purchase order, specify the product or service that is promised to the customer. The typical contract life is less than one month and contains a single performance obligation, to provide conforming goods or services to the customer. Product revenue is recognized at the point in time when control of the product is transferred to the customer, which typically occurs when products are shipped.Service revenue is recognized at the point in time when the service has been provided.

Fair Value Measurements 

The carrying value of trade receivables, accounts payable, and other financial working capital items approximates fair value at June 30, 2018 and December 31, 2017, due to the short maturity nature of these instruments.

Stock-Based Compensation

The Company records compensation expense for stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes-Merton (“BSM”) option pricing model. The Company uses historical data, among other factors, to estimate the expected price volatility, the expected option life, and the expected forfeiture rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. 

As of June 30, 2018, there was approximately $11 of unrecognized compensation expense related to unvested stock options. The Company expects to recognize this expense over the next two years.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant estimates, including the underlying assumptions, consist of economic lives of long-lived assets, realizability of trade receivables, valuation of deferred tax assets/liabilities, inventory, investments, contingent earn-out, and stock compensation expense. It is at least reasonably possible that these estimates may change in the near term.

Recently Adopted Accounting Pronouncement

In January 2016, the FASB issued Accounting Standards Update No. 2016-01 (ASU 2016-01) "Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which amends various aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The Company adopted ASU 2016-01 as of January 1, 2018 using the modified retrospective method for marketable equity securities. This resulted in a $7 reclassification of net unrealized losses from accumulated other comprehensive gain (AOCI) to retained earnings. The adoption of ASU 2016-01 increases the volatility of non-operating income, as a result of the remeasurement of the equity securities. For further information on unrealized gains from equity securities, see Note 2.

Net Loss per Common Share

Basic and diluted net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted-average common shares outstanding during the period. For all periods presented, the common shares underlying stock options have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted-average shares outstanding used to calculate both basic and diluted loss per common shares are the same.

For the three and six months ended June 30, 2018, 7,318 and 7,474 option share equivalents, respectively, have been excluded from the computations of diluted weighted-average shares outstanding.

Reclassification

Certain items related to freight costs in the 2017 financial statements have been reclassified to conform to the 2018 presentation. These reclassifications had no effect on stockholders' equity, net income, or cash flows.

Note 2. Investments

The Company has investments in commercial paper, Treasury Bills, and common equity securities of a private U.S. company.  The commercial paper investment is in U.S. debt with ratings of F1+.  The Treasury Bills have terms ranging from one month to six months at June 30, 2018. 

The Company classifies its investments in commercial paper and Treasury Bills as available-for-sale accounted for at fair value with unrealized gains and losses recognized in accumulated other comprehensive gain on the balance sheet.

Prior to January 1, 2018, the Company accounted for equity securities at fair value with unrealized gains and losses recognized in accumulated other comprehensive gain on the balance sheet. Realized gains and losses on equity securities sold or impaired were recognized in non-operating income on the statement of comprehensive loss.

On January 1, 2018, the Company adopted ASU 2016-01 which changed the way the Company accounted for equity securities. Equity securities are measured at fair value and starting January 1, 2018 unrealized gains and losses are recognized in non-operating income. Upon adoption, the Company reclassified $7 net unrealized losses related to equity securities from accumulated other comprehensive gain to retained earnings. 

The cost and estimated fair value of the Company’s investments are as follows:

	Cost		Gross unrealized gain		Gross unrealized loss			Fair value

Commercial Paper	$	272	$	0	$	0		$	272

The fair value of the commercial paper and treasury bills is based on quoted market prices in an active market. There is not a significant market for the available-for-sale equity security owned by the Company.  The Company has determined the fair value for this equity security based on financial and other factors that are considered level 3 inputs in the fair value hierarchy.

The contingent earn-out relates to the 2014 acquisition of the HazardPRO^TM product line. Management estimated the probability of meeting the revenue targets over the measurement period to determine the fair value of the contingent earn-out, which is considered a level 3 input in the fair value hierarchy.  The contingent earn-out was paid in full during the first quarter of 2018.

The change in level 3 liabilities at fair value on a recurring basis for the three and six months ended June 30, 2018 and 2017 are as follows:

	Three Months Ended June 30					Six Months  Ended June 30

CRITICAL ACCOUNTING ESTIMATES

The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make decisions based upon estimates, assumptions, and factors it considers relevant to the circumstances. These decisions include the selection of applicable accounting principles and the use of judgment in their application, and affect reported amounts and disclosures. Changes in economic conditions or other business circumstances may affect the outcomes of management’s estimates and assumptions. An in-depth description of our accounting estimates can be found in the interim financial statements included in this report and in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017. We have not developed new estimates subsequent to those discussed in our Annual Report.

The following paragraphs discuss the Company’s performance for thethree and six months ended June 30, 2018 and 2017.

RESULTS OF OPERATIONS (in thousands) 

Net Sales

Net sales for the second quarter of 2018 were $1,780, a decrease of $548, or 23.5% over the same period in 2017. Net sales for the six months ended June 30, 2018 were $3,496, a decrease of $502, or 12.6% over the same period in 2017.  The decrease in the second quarter was primarily due to a decline in the number of system orders in both our legacy and HazardPRO product lines.We believe our customers are deferring capital expenditures for larger system orders as they experience record low commodity prices and face the uncertainty of international tariffs.Furthermore, international sales decreased 55% predominantly as the result of decreased sales into Canada, Europe, and Mexico.

Gross Profit

Gross profit for the second quarter of 2018 decreased $352, or 26.6%, over the same period in 2017. Gross profit for the six months ended June 30, 2018decreased $335, or 15.1%, over the same period in 2017. Gross margin, as a percentage of net sales, decreased in the second quarter of 2018 to 54.6%, versus 56.9% in the same period in 2017. Gross margin, as a percentage of net sales, decreased in the six months ended June 30, 2018 to 54.0%, versus 55.6% in the same period in 2017.  The decrease in gross margin percentage during the first and second quarter of 2018 was due to a change in product mix.

12

Operating Expenses

Total operating expenses increased $59, or 6.0%, for the second quarter of 2018 compared to the same period in 2017 and also increased as a percentage of net sales to 58.8% from 42.5%. Total operating expensesincreased$214, or10.5%, for the six months ended June 30, 2018 compared to the same period in2017and alsoincreasedas a percentage of net sales to64.1% from50.7%.  The increases in operating expenses as a percentage of sales were due primarily to decreased revenues in the second quarter of 2018.

● Selling and marketing expenses in the second quarter of 2018 decreased $7, or 1.7%, from the same period in 2017, but increased as a percentage of net sales to 22.5% from 17.5%. Selling and marketing expenses in thesix months ended June 30, 2018increased$51, or6.5%, from the same period of2017, and also increasedas a percentage of net sales to23.9% from19.6%. The decrease in the second quarter resulted primarily from a decrease in commissions paid to outside sales representatives due to decreased sales, partially offset by increased expenses related to the hiring of a business development manager.  The increase for the six months ended June 30, 2018 2018, as compared to the same period in 2017, resulted primarily from the hiring of a business development manager, partially offset by a decrease in commissions paid to outside sales representatives due to decreased sales.

● General and administrative expenses increased $45, or 11.9%, for the second quarter of 2018 compared to the same period in 2017 and also increased as a percentage of net sales to 23.8% from 16.3%. General and administrative expenses increased $133, or 16.2%, for the six months ended June 30, 2018 compared to the same period in 2017 and also increased as a percentage of net sales to 27.3% from 20.5%. The increase for both periods was due to increases in legal and professional expenses and computer supplies, software, and testing.

● Research and development expenses increased $21, or 10.4%, in the second quarter of 2018 from the same period in 2017, and also increased as a percentage of net sales to 12.5% from 8.7%. Research and development expenses increased $30, or 7.1%, in the six months ended June 30, 2018 compared to the same period in 2017, and also increased as a percentage of net sales to 12.9% from 10.6%. The increase for both periods was due to the hiring of additional personnel and increased lab testing and certification expenses for a new product, partially offset by a decrease in contract engineering related to product enhancements.  

Non-Operating Income

Non-operating income increased by $20, or 285.7%, for the second quarter of 2018 compared to the same period in 2017. Non-operating income increased by $34, or 188.9%, for the six months ended June 30, 2018 compared to the same 2017 period. The increase was primarily due to higher interest income in both the first and second quarters of 2018, as compared to the respective prior year periods, primarily the result of higher interest rates on Treasury Bills.

Income (Loss) Before Income Taxes

Loss before income taxes was $48 for the second quarter of 2018, representing a decrease of $391, or 114.0%, compared to income before income taxes of $343 for the same period in 2017. Loss before income taxes was $304 for the six months ended June 30, 2018, representing a decrease of $515, or 244.1%, when compared to income before income taxes of $211 for the same period of 2017. The decrease for the period was the result of lower revenues in the second quarter of 2018 andhigher operating expenses as discussed above.

Income Taxes

The Company's income tax expense percentage decreased to 10.4% for the second quarter of 2018 from 35.0% in the second quarter of 2017 and decreased to 19.4% for the six months ended June 30, 2018 from 34.1% for the six months ended June 30, 2017 due to the enactment of the Tax Jobs and Cuts Act (the "Act") of 2017 in December 2017.  The Act decreased the highest corporate rate to 21% from 39%.

13

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $758 at June 30, 2018 and $963 at December 31, 2017. The decrease was primarily the result of an increase in cash used in operating activities and the payment of the contingent earn-out of $150 in the first quarter of 2018.

Cash used in operating activities was $80 for the six months ended June 30, 2018 as compared to cash generated from operations of $39 for the six months ended June 30, 2017. The $119 decrease was due to the net loss experienced in the first half of 2018 and a decrease in accrued income taxes, partially offset by a decrease in trade receivables. The increase in net loss in the first half of 2018, as compared to the prior year period, was primarily due to decreased revenue for that period.  The decrease in accrued income taxes is due to the net loss.  The decrease in trade receivables is due to the timing of sales and collections on accounts.  

Cash generated from investing activities was $25 and $16 for the six months ended June 30, 2018 and 2017, respectively. During the six months ended June 30, 2018 and 2017, the Company had net proceeds of Treasury Bills with a maturity date of more than three months of $53 and $28, respectively. In addition, we purchased $28 and $12 of property and equipment during the six months ended of 2018 and 2017, respectively.

Cash used in financing activities in the six months ended June 30, 2018 was $150 to pay the contingent earn-out for the technology purchased from Harvest Engineering, Inc. (Harvest) in 2014.  This was the final payment due to Harvest.  There was no cash used or provided by financing activities in the six months ended June 30, 2017.  

Our ongoing cash requirements will be primarily for capital expenditures, research and development, working capital, and growth initiatives. Management believes that our cash on hand and any cash generated from operations will be sufficient to meet our cash requirements through at least the next 12 months.

Future Business Development Activities

The Company continues to seek growth opportunities, both internally through the Company’s existing portfolio of products, technologies and markets, as well as externally through technology partnerships or related-product acquisitions.

Off-balance Sheet Arrangements

As of June 30, 2018, the Company had no off-balance sheet arrangements or transactions.

Nature Of Business And Significant Accounting Policies [Abstract]

Basis Of Presentation

Note 1. Basis of Presentation

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions and regulations of the Securities and Exchange Commission to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements.

This report should be read together with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, including the audited financial statements and footnotes therein.

Management believes that the unaudited financial statements include all adjustments, consisting of normal recurring accruals, necessary to fairly state the financial position and results of operations as of June 30, 2018 and for the three and six-month periods then ended in accordance with accounting principles generally accepted in the United States of America. The results of interim periods may not be indicative of results to be expected for the year.

Nature of Business

Electro-Sensors, Inc. manufactures and markets a complete line of monitoring and control systems for a variety of industrial machinery. The Company uses leading-edge technology to continuously improve its products and make them easier to use, with the goal of manufacturing the industry-preferred product for every market served. The Company sells these products through an internal sales staff, manufacturers’ representatives, and distributors to a wide variety of industries that use the products in a variety of applications to monitor process machinery operations. The Company markets its products to customers located throughout the United States, Canada, Latin America, Europe, and Asia.

Revenue Recognition

On January 1, 2018, the Company adopted Accounting Standards Codification (ASC) Revenue from Contracts with Customers and all related amendments (the Standard), for all contracts using the modified retrospective method. The Standard implements a five-step process for revenue recognition that focuses on transfer of control and defines a contract as “an agreement between two or more parties that creates legally enforceable rights and obligations." The adoption of the Standard did not materially impact the timing and measurement of revenue recognition. As a result, we did not recognize a cumulative effect adjustment to the opening balance of retained earnings.

At contract inception, the Company assesses the goods and services promised to a customer and identifies a performance obligation for each promised good or service that is distinct.In addition, the transaction price for each performance obligation is determined at contract inception.Our contracts, generally in the form of a purchase order, specify the product or service that is promised to the customer. The typical contract life is less than one month and contains a single performance obligation, to provide conforming goods or services to the customer. Product revenue is recognized at the point in time when control of the product is transferred to the customer, which typically occurs when products are shipped.Service revenue is recognized at the point in time when the service has been provided.

Fair Value Measurements 

The carrying value of trade receivables, accounts payable, and other financial working capital items approximates fair value at June 30, 2018 and December 31, 2017, due to the short maturity nature of these instruments.

Stock-Based Compensation

The Company records compensation expense for stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes-Merton (“BSM”) option pricing model. The Company uses historical data, among other factors, to estimate the expected price volatility, the expected option life, and the expected forfeiture rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. 

As of June 30, 2018, there was approximately $11 of unrecognized compensation expense related to unvested stock options. The Company expects to recognize this expense over the next two years.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant estimates, including the underlying assumptions, consist of economic lives of long-lived assets, realizability of trade receivables, valuation of deferred tax assets/liabilities, inventory, investments, contingent earn-out, and stock compensation expense. It is at least reasonably possible that these estimates may change in the near term.

Recently Adopted Accounting Pronouncement

In January 2016, the FASB issued Accounting Standards Update No. 2016-01 (ASU 2016-01) "Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which amends various aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The Company adopted ASU 2016-01 as of January 1, 2018 using the modified retrospective method for marketable equity securities. This resulted in a $7 reclassification of net unrealized losses from accumulated other comprehensive gain (AOCI) to retained earnings. The adoption of ASU 2016-01 increases the volatility of non-operating income, as a result of the remeasurement of the equity securities. For further information on unrealized gains from equity securities, see Note 2.

Net Loss per Common Share

Basic and diluted net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted-average common shares outstanding during the period. For all periods presented, the common shares underlying stock options have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted-average shares outstanding used to calculate both basic and diluted loss per common shares are the same.

For the three and six months ended June 30, 2018, 7,318 and 7,474 option share equivalents, respectively, have been excluded from the computations of diluted weighted-average shares outstanding.

Reclassification

Certain items related to freight costs in the 2017 financial statements have been reclassified to conform to the 2018 presentation. These reclassifications had no effect on stockholders' equity, net income, or cash flows.

Investments

Note 2. Investments

The Company has investments in commercial paper, Treasury Bills, and common equity securities of a private U.S. company.  The commercial paper investment is in U.S. debt with ratings of F1+.  The Treasury Bills have terms ranging from one month to six months at June 30, 2018. 

The Company classifies its investments in commercial paper and Treasury Bills as available-for-sale accounted for at fair value with unrealized gains and losses recognized in accumulated other comprehensive gain on the balance sheet.

Prior to January 1, 2018, the Company accounted for equity securities at fair value with unrealized gains and losses recognized in accumulated other comprehensive gain on the balance sheet. Realized gains and losses on equity securities sold or impaired were recognized in non-operating income on the statement of comprehensive loss.

On January 1, 2018, the Company adopted ASU 2016-01 which changed the way the Company accounted for equity securities. Equity securities are measured at fair value and starting January 1, 2018 unrealized gains and losses are recognized in non-operating income. Upon adoption, the Company reclassified $7 net unrealized losses related to equity securities from accumulated other comprehensive gain to retained earnings. 

The cost and estimated fair value of the Company’s investments are as follows:

	Cost		Gross unrealized gain		Gross unrealized loss			Fair value

The fair value of the commercial paper and treasury bills is based on quoted market prices in an active market. There is not a significant market for the available-for-sale equity security owned by the Company.  The Company has determined the fair value for this equity security based on financial and other factors that are considered level 3 inputs in the fair value hierarchy.

The contingent earn-out relates to the 2014 acquisition of the HazardPRO^TM product line. Management estimated the probability of meeting the revenue targets over the measurement period to determine the fair value of the contingent earn-out, which is considered a level 3 input in the fair value hierarchy.  The contingent earn-out was paid in full during the first quarter of 2018.

The change in level 3 liabilities at fair value on a recurring basis for the three and six months ended June 30, 2018 and 2017 are as follows:

	Three Months Ended June 30					Six Months  Ended June 30

The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. 

As of June 30, 2018, there was approximately $11 of unrecognized compensation expense related to unvested stock options. The Company expects to recognize this expense over the next two years.

Use Of Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant estimates, including the underlying assumptions, consist of economic lives of long-lived assets, realizability of trade receivables, valuation of deferred tax assets/liabilities, inventory, investments, contingent earn-out, and stock compensation expense. It is at least reasonably possible that these estimates may change in the near term.

Recently Adopted Accounting Pronouncement

Recently Adopted Accounting Pronouncement

In January 2016, the FASB issued Accounting Standards Update No. 2016-01 (ASU 2016-01) "Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which amends various aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The Company adopted ASU 2016-01 as of January 1, 2018 using the modified retrospective method for marketable equity securities. This resulted in a $7 reclassification of net unrealized losses from accumulated other comprehensive gain (AOCI) to retained earnings. The adoption of ASU 2016-01 increases the volatility of non-operating income, as a result of the remeasurement of the equity securities. For further information on unrealized gains from equity securities, see Note 2.

Net Loss per Common Share

Net Loss per Common Share

Basic and diluted net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted-average common shares outstanding during the period. For all periods presented, the common shares underlying stock options have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted-average shares outstanding used to calculate both basic and diluted loss per common shares are the same.

For the three and six months ended June 30, 2018, 7,318 and 7,474 option share equivalents, respectively, have been excluded from the computations of diluted weighted-average shares outstanding.

Reclassification

Reclassification

Certain items related to freight costs in the 2017 financial statements have been reclassified to conform to the 2018 presentation. These reclassifications had no effect on stockholders' equity, net income, or cash flows.
